Portable electronic devices can be constructed using a variety of different approaches. For example, a “bucket” type approach can be used in which a first housing component serves as a bucket into which electronic device components are placed, and a second housing component serves as a cover for the bucket. This arrangement secures the electronic device components between the first and second housing components. As a variation of this, some or all of the electronic device components can be assembled into the cover for the bucket, and the cover can subsequently be rotated into the bucket to close the device.
Other known portable electronic devices can be constructed by inserting components into a hollow housing element. For example, an electronic device can be constructed using a tubular structure (e.g., a flattened tube or a hollow rectangular tube) into which electronic device components can be inserted. The electronic device components can be inserted into the tubular structure from one or both ends, and connected within the structure. For example, one or more circuits inserted from opposite ends of the tubular structure can be connected through an opening for a window in the structure. The structure can be capped at one or both ends to ensure that the components remain fixed within the tubular structure, and to provide interface components (e.g., connectors, buttons, or ports) for the device.
Unfortunately, however, as portable electronic device continue to be made smaller, thinner and/or more powerful, there remains a continuing need to provide improved techniques and structures for providing housings for portable electronic devices.
Embodiments are described herein in the context of housings for electronic devices. According to one aspect, adjoining surfaces of electronic device housings can be mounted or arranged such that adjoining surfaces are flush to a high degree of precision. The electronic devices can be portable and in some cases handheld.
The invention pertains to apparatus, systems and methods for assembling electronic devices, namely, portable or handheld electronic devices.
The invention may be implemented in numerous ways, including, but not limited to, as a method, system, device, or apparatus. Several embodiments of the invention are discussed below.
As a method for assembling a device housing of an electronic device, one embodiment can, for example, provide an outer glass member for the device housing, and provide a protective side structural member having a receptive plane that is to receive the outer glass member. A liquid adhesive can be applied to a portion of the outer glass member and/or a portion of the protective side structural member. The outer glass member can be positioned adjacent to the receptive plane of the protective side structural member. A first a first force can be applied to push the outer glass member against a planar reference surface, and a second force can be applied to push the protective side structural member against the planar reference surface. The second force is independently applied from the first force. Still further, the liquid adhesive can be cured into a solid bonding material that bonds together the outer glass member and the protective side structural member, thereby assembling the outer glass member with the protective side structural member. Subsequently, the first force and the second force can be removed.
As a method for assembling a device housing of an electronic device, one embodiment can, for example, provide an outer housing member for the device housing, and provide a protective side structural member. A first force can then be applied to push the outer housing member against a planar reference surface, and a second force can be applied to push the protective side structural member against the planar reference surface. The second force is independently applied from the first force. The outer housing member and the protective side structural member can then be secured together, thereby assembling a portion of the device housing including at least the outer housing member with the protective side structural member. The assembled portion of the device housing can then be removed from the planar reference surface.
As an electronic device enclosure, one embodiment can, for example, include at least an outer periphery member defining a side surface for the electronic device enclosure, and an internal structure secured to an inner surface of the outer periphery member. The internal structure can be offset from front and back planar boundaries of the outer periphery member. The electronic device enclosure can further include a front cover assembly placed and secured adjacent the front planar boundary of the outer peripheral boundary, thereby providing a front surface for the electronic device enclosure. The front cover assembly can include a front cover member and a protective side member, the protective side member being provided against and around the sides of the front cover member.
According to one aspect of the present invention, an apparatus includes a cover part that includes at least one attachment protruding therefrom. The apparatus also includes a housing part and at least one electronic component. The housing part includes at least one receptacle configured to receive the attachment. The receptacle is defined at least partially on a first side and is configured to capture the attachment. The cover part is interfaced with a second side of the housing part when the attachment is captured in the receptacle. Finally, the electronic component is arranged within an inner volume defined by at least the housing part. In one embodiment, the cover part is in substantially direct contact with the second side of the housing part when the attachment is captured in the receptacle.
Other aspects and advantages of the invention will become apparent from the following detailed description taken in conjunction with the accompanying drawings which illustrate, by way of example, the principles of the invention.
The accompanying drawings, which are incorporated into and constitute a part of this specification, illustrate one or more example embodiments and, together with the description of example embodiments, serve to explain the principles and implementations associated with the specification.
Embodiments are described herein in the context of a housing for an electronic device. The housing can make use of an outer member. The outer member can be aligned, protected and/or secured with respect to other portions of the housing for the electronic device. The electronic device can be portable and in some cases handheld.
According to one aspect, adjoining surfaces of electronic device housings can be mounted or arranged such that adjoining surfaces are flush to a high degree of precision. Edges of portable electronic devices are susceptible to impact force, such as when dropped. According to another aspect, protective sides can be provided on edges of electronic device housings so to dissipate impact forces and thus reduce damage to electronic device housings. According to still another embodiment, an electronic device housing can have one or more of its exposed major surfaces (e.g., front or back surfaces) formed of glass. The glass surfaces can be protected by the protective sides and/or can be aligned so that the top surfaces of the glass surfaces and the protective sides can be substantially flush.
According to another aspect, apparatus, systems and methods for robustly attaching a cover portion of an electronic device to a bottom portion, e.g., a housing portion, of the electronic device are described. The cover portion may generally include a frame (e.g., interface member) into which n outer member (e.g., glass member) has been inserted. Attachment members (e.g., arms, tabs) can be coupled to, e.g., insert molded into, a cover portion, and can be arranged to substantially engage with a housing portion such that the cover portion is effectively held against the housing portion. The attachment members can be used to fasten the cover portion to the housing. In general, receptacles of the housing portion are arranged to substantially capture, mate or otherwise engage attachment members of the cover portion.
According to another aspect, a cover assembly can be configured to support and protect an outer glass member. The cover assembly can form part of a housing for an electronic device. The cover assembly can also include a distinct glass lens, attachment members, structural support.
According to still another aspect, an optical lens can be formed from a formed optical adhesive. The optical lens can, for example, be used as a lens for a camera flash of a portable electronic device. The optical lens can be provided between the camera flash and the cover member A mold can be used to form a lens from the optical adhesive.
The following detailed description is illustrative only, and is not intended to be in any way limiting. Other embodiments will readily suggest themselves to skilled persons having the benefit of this disclosure. Reference will now be made in detail to implementations as illustrated in the accompanying drawings. The same reference indicators will generally be used throughout the drawings and the following detailed description to refer to the same or like parts. It should be appreciated that the drawings are generally not drawn to scale, and at least some features of the drawings have been exaggerated for ease of illustration.
In the interest of clarity, not all of the routine features of the implementations described herein are shown and described. It will, of course, be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made in order to achieve the developer's specific goals, such as compliance with application and business related constraints, and that these specific goals will vary from one implementation to another and from one developer to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking of engineering for those of ordinary skill in the art having the benefit of this disclosure.
According to one aspect, a housing for an electronic device can include an outer periphery member that forms the sides of the electronic device. The outer periphery member can define a volume into which electronic device components can be placed. To obtain the components within the device, front and back covers can be placed over the front and back surfaces of the outer periphery member.
An outer periphery member can provide a variety of attributes to the electronic device including for example, structural, functional, cosmetic, or combinations of these. The outer periphery member may for example form at least a portion of the right, left, top and bottom sides of the device. As such, the outer periphery member may surround components that are placed in the device back to front, front to back or center to back and front (e.g., components inserted within the volume defined by the outer periphery member). The outer periphery member may be formed from one or more elements. The elements may be similar or different depending on the dimensions or shape of the device, as well as functional or structural considerations (e.g., outer periphery member elements serving as an antenna for tuning electromagnetic waves). If several elements are combined to form the outer periphery members, the elements can be connected in any suitable manner to form a single unit having adequate structural, functional, or cosmetic properties. In some cases, the outer periphery member can be formed from several elements that act as a single integral unit (e.g., a unitary part). For example, the elements can be integrally formed together.
In some embodiments, the outer periphery member can define a band that forms an enclosed volume having a front and back open area. The band may define a ring-like structure that wraps around some or all of the components of the electronic device. The electronic device can include a variety of components such as housing elements, electronics, structural members, or combinations of these. In some cases, one or more structural members (e.g., a mid-plate) can be connected to the outer periphery member within the volume enclosed by the outer periphery member to receive and support components, or enhance the structural properties of the outer periphery member.
In some embodiments, the electronic device can include front and/or back cover assemblies operative to cap the volume defined by the outer periphery member. The cover assemblies can be positioned relative to the open areas of the outer periphery member such that the front and back cover assemblies are placed adjacent to the front and back surfaces of the outer periphery member, respectively. The cover assemblies can include any suitable feature, including for example housing portions, access points, electronics, structural members, aesthetic members, or combinations of these. In some cases, the cover assemblies can include one or more features for securing or retaining electronic device components within the volume enclosed by the outer periphery member.
The outer periphery member and the front and back cover assemblies can provide some or all of the exterior surfaces of the device, and thus define the outer periphery form or look and feel of the electronic device. In particular, the front cover can substantially form the front surface of the device, the back cover can substantially form the back surface of the device, and the outer periphery member can substantially form the top, bottom, left and right surfaces of the device. It will be understood, however, that some or all of the cover assemblies can instead or in addition provide part of the top, bottom, left or right surfaces of the device, and that some or all of the outer periphery member can provide part of the front or back surfaces of the device.
Because the cover assemblies can define exposed surfaces of the electronic device, one or both of the cover assemblies can include components, coatings or finishes that enhance the functional, cosmetic and/or aesthetic characteristics of the assemblies. For example, one or both of the cover assemblies can include a transparent or translucent window through which input/output components are able to be used by the user. For example, one output component that can be used is a display device that can present information to the user via the cover assembly. As another example, one input component that can be used is a touch sensor (e.g., touch sensor) that can receive user input from the user via the cover assembly. As another example, one or both of the cover assemblies can include a cosmetic component for enhancing the aesthetic appeal of the device. In some embodiments, the cosmetic component can cause the cover assembly to be substantially opaque in some areas (e.g., on a back cover assembly), yet transparent or translucent in other areas (e.g., on a front cover assembly through which content generated by the display device is provided). In other words, the cover assembly can include a transparent or translucent window that is provided on a portion of the cover assembly. The cover assemblies can also support other function features, such as a camera opening, a lens, a light, a sensor, etc.
Internal components of the electronic device can be assembled using any suitable approach. In some embodiments, the internal components can define one or more layers that are placed within the outer periphery member. For example, layers can initially be placed near the center of the volume defined by the outer periphery member, and subsequently be added towards one or both of the front and back surfaces of the device. Each layer added to the device can be coupled or fit to a layer previously inserted and attached to the device.
To further retain component layers, the electronic device can include an internal platform providing a structural element for the outer periphery member and to which component layers can be coupled. In some embodiments, the internal platform can provide attachment points for the various layers placed within the electronic device. The internal platform may be placed within the height of the outer periphery member such that it is substantially near the middle of the outer periphery member (e.g., at half the height of the outer periphery member), thus defining a mid-plate. In particular, the mid-plate can form a substantially H-shape cross-section with the outer periphery member, thus providing enhanced structural properties. Electronic device components or layers can be assembled to both the front and back surfaces of the mid-plate (e.g., the mid-plate separates the internal volume of the outer periphery member into two distinct regions or pockets). The mid-plate can be secured to the outer periphery member (e.g., using welding, or formed with or made integral with the outer periphery member. Although called a plate or platform it will be understood that the internal platform can take a variety of non-planar forms, including various formations that include steps, offsets, curved surfaces, or combinations of these.
Electronic device 100 can have any suitable shape, including for example a shape delimited by front surface 110, back surface 112, left surface 114, right surface 116, top surface 118 and bottom surface 119 (not shown in the cross-section). Each surface can be substantially planar, curved, or combinations of these. The surfaces can include one or more chamfers, detents, openings, dips, extensions, or other features modifying the smoothness of the surfaces.
Electronic device 100 can be constructed using any suitable structure, including for example using outer periphery member 120. Outer periphery member 120 can surround or wrap some or all of the electronic device such that the outer periphery member defines an internal volume 122 into which electronic device components can be placed. For example, outer periphery member 120 can wrap around the device such that the external surfaces of outer periphery member 120 define left surface 114, right surface 116, as well as top surface 118 and bottom surface 119 of the device. To provide a desired functionality to a user, the electronic device can include several components placed within the device, for example within volume 122.
The outer periphery member can have a particular height (e.g., the device height h) such that the outer periphery member encloses volume 122 into which electronic device components can be assembled. The thickness (e.g., outer periphery member thickness t), length (e.g., device length l), height (e.g., device height h), and cross-section of the outer periphery member can be selected based on any suitable criteria including for example based on structural requirements (e.g., stiffness, or resistance to bending, compression, tension or torsion in particular orientations). In some embodiments, the outer periphery member can serve as a structural member to which other electronic device components can be mounted. The outer periphery member can include one or more depressions, recesses, channels, protrusions, or openings for supporting components or for providing structural support for the device. In some embodiments, an opening can be used to provide access to one or more internal components contained within the outer peripheral member.
Outer periphery member 120 (or device 100) can have any suitable cross-section. For example, outer periphery member 120 can have a substantially rectangular cross-section. In some embodiments, outer periphery member 120 can instead or in addition have a cross-section in a different shape, including for example a circular, oval, polygonal, or curved cross-section. In some embodiments, the shape or size of the cross-section can vary along the length or width of the device (e.g., an hourglass shaped cross-section).
Electronic device components can be placed within volume 122 using any suitable approach. For example, electronic device 100 can include components 130 and 132 can be inserted into volume 122. Each of components 130 and 132 can include individual components, or several components assembled together as a component layer or stack, or include several distinct layers of components to insert within volume 122. In some embodiments, components 130 and 132 can each represent several components stacked along the height of the device. The component layers can be electrically coupled to each other to enable data and power transfers, as required for the proper operation of electronic device 100. For example, the component layers can be electrically coupled using one or more of a PCB, flex, solder, SMT, wires, connectors, or combinations of these. The component layers can be inserted into outer periphery member 120 using any suitable approach. For example, components 130 and 132 can all be inserted from front surface 110 or from back surface 112 (e.g., back to front, front to back, or middle to front and back). Alternatively, the components can be inserted from both front surface 110 and back surface 112.
In some embodiments, one or more of the components can serve as a structural element. Alternatively, electronic device 100 can include a distinct structural element placed within volume 122 and coupled to outer periphery member 120. For example, electronic device 100 can include one or more internal member or platform 140, which can serve as a mounting points or regions for helping secure, hold or pack one or more component layers (e.g., attaching component 130 to the back surface of internal platform 140, and component 132 to the front surface of internal platform 140). Internal platform 140 can be coupled to outer periphery member 120 using any suitable approach, including for example using snaps, fasteners, flexures, welds, glue, or combinations of these. Alternatively, internal platform 140 may even be part of the outer periphery member (e.g., machined, extruded, or cast, or integrally formed as a single unit). The internal platform can have any suitable size, including for example a size that is smaller than the internal volume of outer periphery member 120.
Internal platform 140 can be positioned at any suitable height within outer periphery member 120, including for example substantially at half the height of outer periphery member 120. The resulting structure (e.g., outer periphery member 120 and internal platform 140) can form an H-shaped structure that provides sufficient stiffness and resistance to tension, compression, torsion and bending.
The internal platform, inner surfaces of the outer periphery members, or both can include one or more protrusions, depressions, shelves, recesses, channels, or other features for receiving or retaining electronic device components. In some cases, the internal platform, outer periphery member or both can include one or more openings for coupling components located in the front and back regions. The size of each region can be selected based on any suitable criteria, including for example operational needs of system, numbers and types of electrical components in the device, manufacturing constraints of the internal platform, or combinations of these. The internal platform can be constructed as a distinct component constructed from any suitable material (e.g., plastic, metal or both), or instead defined from an existing electronic device component placed within the volume defined by the outer periphery member. For example, the internal platform can be formed by a printed circuit board or chip used by the device.
In some embodiments internal platform 140 and/or opening 122 can include one or more electrically conductive elements for providing electrical connections between the components. For example, internal platform 140 and/or opening 122 can include one or more PCB, flex, wire, solder pad, cable, connector, or other electrically conductive mechanism for connecting components within the electronic device.
Electronic device 100 can include front cover assembly 150 and back cover assembly 160 defining the front and back surfaces, respectively, of electronic device 100. The front and back cover assemblies can include one or more components, or can include at least a front member and a back member that form some or all of the outer front and back surfaces of the device. Front and back cover assemblies 150 and 160 can be flush, recessed or protruding relative to the front and back surfaces of outer periphery member 120. In some embodiments, one or both of front and back cover assemblies 150 and 160 can include delicate or fragile components. To protect the components from damage during use or when dropped, one or both of the cover assemblies can be flush or sub-flush relative to the outer periphery member to prevent edges from engaging other surfaces. Alternatively, the one or more of the cover assemblies can be “proud” (i.e., protrude above the edge of the outer peripheral member). In some embodiments, one or both of front cover assembly 150 and back cover assembly 160 can include one or more display regions through which one or more display devices can be viewed. The one or more display regions can be defined by boarders provided by coating or finish can be applied the front member or the back member. Similarly, the coating or finish can also be applied to the front member or the back member can also provide a masking effect to hide internal components.
In some embodiments, the electronic device can be substantially made of glass. For example, portions of the electronic device housing can have at least 75% of its exterior as glass. In one implementation, one or both of the cover assemblies can be glass while side surface are some material other than glass (e.g., metal, plastic).
In some embodiments, the housing a portable electronic device can be banged or rub against various surfaces. When plastic or metal housing surfaces are used, the surfaces can tend to become scratched. On the other hand, glass housing surfaces (e.g., glass cover assemblies) can be more scratch resistant. Moreover, glass housing surfaces can offer radio transparency, while metal housing surfaces can disturb or hinder radio communications. In one embodiment, an electronic device housing can use glass housing members (e.g., glass cover assemblies) for a front surface and a back surface of the electronic device housing. For example, a front surface formed from a glass housing member can be transparent to provide visual access to a display device positioned behind the glass housing member at the front surface, while a back surface formed from a glass housing member can be transparent or non-transparent. Non-transparency, if desired, can conceal any interior components within the electronic device housing. In one embodiment, a surface coating or film can be applied to the glass housing member to provide non-transparency or at least partial translucency. Such a surface coating or film can be provided on an inner surface or an outer surface of the glass housing member.
In some embodiments, one or both of front and back cover assemblies 150 and 160 can provide side protection for the front and back members. When the front member is formed of glass, the side protection can serve to protect the front member from damage if subjected to impact forces. When the back member is formed of glass, the side protection can serve to protect the back member from damage if subjected to impact forces.
In some embodiments, one or both of front and back cover assemblies 150 and 160 can provide attachment members that can serve to attach front and back cover assemblies 150 and 160. For example, front cover assembly 150 can include attachment members to attach front cover assembly 150 to internal platform 140 and/or outer periphery member 120. Back cover assembly 160 can include attachment members to attach back cover assembly 160 to internal platform 140 and/or outer periphery member 120.
In some embodiments, one or both the front and back members of front and back cover assemblies 150 and 160 can be formed of glass. The front or back member formed primarily of glass can include one or more pieces of glass. For example, the different pieces of glass can have different configurations, optical properties, and/or cosmetic appearance.
Outer periphery member 220 can have any suitable size, which can be determined based on any suitable criteria (e.g., aesthetics or industrial design, structural considerations, components requires for a desired functionality, or product design). The outer periphery member can have any suitable cross-section, including for example a variable cross-section or a constant cross-section. In some embodiments, the cross-section of the ring can be selected based on desired structural properties for the outer periphery member. For example, the cross-section of outer periphery member 220 can be substantially rectangular, such that the height of the outer periphery member is substantially larger than the width of the outer periphery member. This can provide structural stiffness in compression and tension, as well as bending.
In some embodiments, the dimensions of the outer periphery member cross-section can be determined relative to the dimensions of the internal platform cross section. For example, the outer periphery member height can be in a range of 5 to 15 times the height of the internal platform, for example 8 to 12 times, 9 to 11 times, or approximately 10 times the height of the internal platform. In one implementation, the height of the outer periphery member can be approximately 9 mm, and the height of the internal platform can be approximately 0.9 mm.
As another example, the width of the outer periphery member can be in a range of 8 to 25 times the width of the internal platform, for example 12 to 20 times, 15 to 18 times, or approximately 16 times the internal platform width. For example, the width of the outer periphery member can be 3 mm and the width of the internal member can be 50 mm. In some embodiments, the height of the internal platform can be related to the width of the outer periphery member. For example, the width of the outer periphery member can be 1 to 8 times the height of the internal platform, such as 2 to 6 times or approximately 4 times the height of the internal platform. In one implementation, the height of the internal platform can be approximately 0.7 mm and the width of the outer periphery member can be approximately 2.5 mm. In some embodiments, the height of the outer periphery member can be related to the width of the internal platform. For example, the width of the internal platform can be 3 to 10 times the height of the outer periphery member, such as 4 to 8 times, 5 to 7 times, or approximately 6 times the height of the outer periphery member. For example, the width of the internal platform can be approximately 5.5 mm and the height of the outer periphery member can be approximately 0.9 mm.
In some embodiments, outer periphery member 220 can include one or more openings, knobs, extensions, flanges, chamfers, or other features for receiving components or elements of the device. The features of the outer periphery member can extend from any surface of the outer periphery member, including for example from internal surfaces (e.g., to retain internal components or component layers), or from external surfaces. In particular, outer periphery member 220 can include a slot or opening 224 for receiving a card or tray within the device. Opening 224 can be aligned with one or more internal components operative to receive and connect to an inserted component (e.g., an inserted SIM card). As another example, outer periphery member 220 can include connector opening 225 (e.g., for a 30-pin connector) through which a connector can engage one or more conductive pins of electronic device 200. Outer periphery member 220 can include openings 226 and 227 for providing audio to a user (e.g., an opening adjacent to a speaker), or receiving audio from a user (e.g., an opening adjacent to a microphone). Outer periphery member 220 can instead or in addition include an opening for an audio connector or power supply (e.g., opening 228), or features 229 for retaining and enabling a button such as a volume control or silencing switch.
The various features of outer periphery member 220 can be constructed using any suitable approach and at any suitable time. In some embodiments, the features can be constructed as part of a process that creates outer periphery member 220 from a single piece of material that is manufactures into the final shape of outer periphery member 220 (e.g., using a machining process). In some embodiments, several pieces of material can instead or in addition be shaped individually and combined into outer periphery member 220. The various features can then be created as part of each individual piece, or once the entire outer periphery member has been assembled. Outer periphery member 220 can be constructed from any suitable material, including for example a metal (e.g., steel or aluminum), plastic (e.g. polyurethane, polyethylene or polycarbonate), composite material, or any combination thereof. In some embodiments, outer periphery member 220 can be constructed from the combination of several materials.
In some embodiments, outer periphery member 220 can have a functional use or purpose in addition to serving as a cosmetic component or as a structural component. For example, outer periphery member 220 can be used as part of an antenna for capturing electromagnetic waves radiated as part of a communications network. In some cases, outer periphery member 220 can be used as parts of more than one antenna.
In some embodiments, one or more portions of outer periphery member 220 can be treated to provide an aesthetically pleasing component. In particular, left surface 214, right surface 216, top surface 218, and bottom surface 219 can be treated using a cosmetic surface treatment such as, for example, polishing, coating (e.g., using a dye or coloring material, or a material providing an optical effect), glazing, thin film deposition, grinding, superfinishing, or any other suitable process. In some embodiments, front or back surfaces of outer periphery member 220 can instead or in addition be provided with a cosmetic treatment (e.g., for regions of the outer periphery member that may not be covered by back and front cover assemblies 250 and 260).
To reduce the overall weight, size or both of electronic device 200, the thickness of outer periphery member 220 can be selected such that outer periphery member 220 is only minimally resistant to one or more of bending, torsion, tension, compression, or other deformation of the band. For example, outer periphery member 220 can be more resistant to tension and compression, but less resistant to bending or torsion. To provide sufficient resistance to all types of deformation, electronic device 200 can include a structural component placed within volume 222. In some embodiments, one or more of the internal components of the electronic device can be connected to the outer periphery member and serve as a structural component. For example, a circuit board (with or without a separate stiffening element) can be connected to opposite portions of outer periphery member 220. Alternatively, a distinct and dedicated structural component can be coupled to outer periphery member 220. In the example of
Internal platform 240 can cover any suitable area within volume 222. Internal platform 240 can include any suitable features for securing or connecting electronic device components, such as one or more snaps, prongs, chamfers, extends, openings, access points, doors, or combinations of these. In some cases, internal platform 240 can include one or more dedicated features for receiving or securing specific electrical components, such as speakers, microphones, audio jacks, cameras, light sources, chips, or combinations of these.
Internal platform 240 can be constructed using any suitable approach. In some embodiments, internal platform 240 can be constructed from a single material or as a combination of several materials. For example, internal platform 240 can include one or more metal elements (e.g., included in extensions used to connect internal platform 240 to outer periphery member 220) around which a plastic can be molded to form internal platform 240. Some portions of the metal elements of internal platform 240 can extend beyond the edges of the plastic periphery so that the internal platform can be coupled to the outer periphery member via the metal elements. For example, the exposed metal elements can be connected to the outer periphery member using welding, soldering, heat staking, an adhesive, tape, a fastener, or any other connection mechanism. The outer periphery member can include one or more counterpart features on internal surfaces of the outer periphery member for retaining or receiving internal platform 240. The connection between the metallic portions of internal platform 240 and outer periphery member 220 can serve to ground particular electronic device components (e.g., components 230 and 232).
Internal platform 240 can be coupled to any suitable portion of outer periphery member 220. For example, internal platform 240 can be assembled within the height of outer periphery member 220 (e.g., based on the position of contact points or regions of the outer periphery member). The distribution of the contact points can be selected based on structural considerations, including for example based on a desired resistance to torsion or bending. In particular, the electronic device can include at least four contact points or regions distributed within outer periphery member 220 (e.g., near the corners of the outer periphery member). As another example, internal platform 240 can include contact regions along the straight portions of outer periphery member 220. As still another example, stepped regions of internal platform 240 can be coupled to the front or back surfaces of outer periphery member 220 (e.g., on opposite portions of the front or back surfaces).
In some embodiments, internal platform 240 can be placed within the height of outer periphery member 220 such that components 230 and 232 can be placed on both the front and back surfaces of internal platform 240. For example, components 230 can be inserted from back surface 212, and components 232 can be inserted from front surface 210. Components 230 and 232 can be coupled to internal platform 240 for security, and can instead or in addition be electrically connected to each other through an opening in internal platform 240. In some embodiments, some components 230 and 232 can first be coupled to back and front cover assemblies 250 and 260, respectively, before being inserted in volume 222 and coupled to outer periphery member 220. In effect, by its position internal platform 240 can define back and front pockets or regions within volume 222 in which electronic device components can be placed. The size of each pocket or region can be determined based on any suitable criteria, including for example the number and size of components to place in each region, the required position of internal platform 240 relative to outer periphery member 220 (e.g., if available positions are limited due to structural requirements), or combinations of these.
To retain components within volume 232, electronic device 200 can include front cover assembly 250 and back cover assembly 260 providing the back and front surfaces of the electronic device, respectively. Each cover assembly can be coupled to outer periphery member 220 using any suitable approach, including for example using an adhesive, tape, mechanical fastener, hooks, tabs, or combinations thereof. In some embodiments, one or both of cover assemblies 250 and 260 can be removable, for example for servicing or replacing electronic device components (e.g., a battery). In some embodiments, cover assemblies 250 and 260 can include several distinct parts, including for example a fixed part and a removable part. The inner surfaces of front cover assembly 250 and back cover assembly 260 can include any suitable feature, including for example one or more ridges, hooks, tabs, extensions, or any combination thereof for retaining the covers or ensuring proper alignment of the covers. The features of cover assemblies 250 and 260 can interact with corresponding features of outer periphery member 220) or other components of the electronic device to ensure proper placement of the covers. Front cover assembly 250 and back cover assembly 260 can be positioned in any suitable manner relative to outer periphery member 220.
Back cover assembly and front cover assembly can be coupled to any suitable portion of outer periphery member. In some embodiments, back cover assembly and front cover assembly can be connected relative to outer periphery member in the same or different manners. In the example of electronic device, both back cover assembly and front cover assembly can be positioned over the back and front surfaces, respectively, of outer periphery member. In some embodiments, one or both of back cover assembly and front cover assembly can only partially cover back surface and front surface, respectively. For example, one or both of back cover assembly and front cover assembly can be placed within the periphery of outer periphery member (e.g., recessed within the outer periphery member).
Returning to electronic device 200 (
In the example of
In some embodiments, glass plate 254 can include a cosmetic finish hiding from view internal components of the electronic device. For example, an opaque layer can be applied region 259 surrounding display 255 to hide from view the non-display portions of the display circuitry. Because one or more sensors may receive signals through glass plate 254, the opaque layer can be selectively removed, or selected to allow signals to pass through the glass plate to the sensor behind the plate. For example, glass plate 254 can include regions 259a and 259b through which sensors (e.g., a camera, infrared sensor, proximity sensor, or ambient light sensor) can receive signals.
In some embodiments, front cover assembly 250 can support or enable one or more interfaces by which a user can use the electronic device. For example, glass plate 254 can support a touch interface (e.g., a touch pad or a touch screen) for controlling electronic device processes and operations. As another example, front cover assembly 250 can include one or more buttons or sensors (described above) for interacting with the device. In some cases, buttons, switches or other interface elements can be instead or in addition incorporated in outer periphery member 220 or back cover assembly 260. Electronic device 200 can include any other suitable interface for interacting with a user, including for example display circuitry, a projector, audio output circuitry (e.g., speakers or a an audio port), a haptic interface (e.g., a motor for creating vibrations, or a power source for providing an electrical stimulus), or combinations of these.
To enhance the cosmetic or aesthetic appeal of electronic device 200, one or all of outer periphery member 220, front cover assembly 250 and back cover assembly 260 can be finished using an appropriate process. For example, one or more of polishing, coating (e.g., using a dye or coloring material, or a material providing an optical effect), glazing, thin film deposition, grinding, superfinishing, or any other suitable process can be applied to electronic device components. In some embodiments, one or more glass surfaces (e.g., of front cover assembly 250 or of back cover assembly 260) can be finished to provide an aesthetically pleasing appearance, for example using one or more masks, coatings (e.g., photochromatic or dichroic), ink layers, or combinations of these. The particular finishes applied to the glass surfaces of front cover assembly 250 and back cover assembly 260 can be selected so that front and back surfaces 214 and 216 have similar or different appearances. In some embodiments, a glass surface can be treated to resist wear or impacts (e.g., scratch resistance), oils from touching, or any other external force applied to the device.

With parts of an electronic device housing being arrangement in a stack, there can be cumulative tolerances which can make alignment less precise. According to one aspect, adjoining surfaces of electronic device housings can be mounted or arranged such that adjoining surfaces are flush to a high degree of precision. Edges of portable electronic devices are susceptible to impact force, such as when dropped. According to another aspect, protective sides can be provided on edges of electronic device housings so to dissipate impact forces and thus reduce damage to electronic device housings. According to still another embodiment, an electronic device housing can have one or more of its exposed major surfaces (e.g., front or back surfaces) formed of glass. The glass surfaces can be protected by the protective sides and can be aligned so that the top surfaces of the glass surfaces and the protective sides can be substantially flush.
The housing member alignment process 400 provides 402 an outer housing member for a device housing, namely, an electronic device housing, can be provided at an assembly region (e.g., assembly station). In addition, a protective side structural member having a receptive plane for receiving the outer housing member can be provided 404.
The outer housing member can be positioned 406 adjacent to the receptive plane of the protective side structural member. In order to ensure proper alignment to a high degree of flushness, a first force is applied 408 to push the outer housing member against a planer reference surface. Here, the planer reference surface can pertain to a flat steel surface provided at the assembly region. In one implementation, the planer reference surface can be coated with a non-stick coating (e.g. Teflon). Further, a second force can be applied 410 to push the protective side structural member against the planar reference surface. Typically, the second force can also push the protective side structural member against the outer housing member. The protective side structural member can then be secured 412 to the outer housing member. As a result, the outer housing member and the protective side structural member, once secured 412, can represent an assembled portion of the device housing. Thereafter, the assembled portion can be removed 414 from the assembly region. After the assembled portion has been removed 414, the housing member alignment process 400 can end.
The housing member alignment process 600 can provide 602 an outer class member for an electronic device housing. A protective side structural member having a receptive plane for receiving the outer glass member can also be provided. A liquid adhesive can then be applied 606 to a portion of the outer glass member and/or a portion of the protective side structural member. The outer glass member can then be positioned 608 adjacent to the receptive plane of the protective side structural member. To impose accurate alignment that yields a high degree of flushness, a first force can be applied 610 to push the outer glass member against a planar reference surface. A second force can also be applied 612 to push the protective side structural member against the planar reference surface. This ensures that the outer glass member and the protective side structural member are positioned such that a top surface of both are tightly adjacent and flush. Thereafter, the liquid adhesive can be cured 614. For example, the members being assembled together into an assembled part can be placed in an oven to accelerate the curing of the liquid adhesive. Once the protective side structural member and the outer glass member are secured by the cured adhesive, the assembled part can be removed 606 from the oven and the first and second forces can be removed. At this point, the assembled part includes the outer glass member together with the protective side structural member. Additionally, given the manner in which the members were assembled into the assembled part, the top surface of the outer glass member is flush with new top surface of the protective side structural member. Following the block 616, a housing member alignment process 600 can end.
In one embodiment, the flushness provided by the alignment processing can be not more than at most 80 mm from being precisely plush. In another embodiment, the flushness provided by the alignment processing can be not more than 60 mm from being precisely flush. In still another embodiment, the flushness provided by the alignment processing can be not more than 40 mm from being precisely flush.
The assembled part can have parts of glass, polymer and/or metal. In one particular embodiment, the outer glass member 700 is glass, such as alumino-silicate glass; the protective side structural member 702 is polymer, such as polyarylamide; and the outer periphery member 716, the internal structure 718 and the attachment arms can be metal, such as stainless steel.
The various members, parts or assemblies of the electronic device housing 900 can be formed of any of a variety of materials, e.g., glass, polymers or metal. In one embodiment, the outer housing member 902 is glass, the outer periphery member 908 is formed from metal or polymer (e.g., plastic), and the another outer housing member 912 is formed from glass, polymer (e.g., plastic) or metal. The interface member 904 can be formed of a polymer or from a combination of materials. For example, the protective side members 906 are to be strong; hence, a structurally strengthened polymer, such as polyarylamide, can be utilized. Also as an example, the securing features 910 can be formed from metal for increased strength. The securing features 910 if formed of metal can be combined with the balance of the interface member 904 by an over-molding process.
The electronic device housing 1000 can also include an internal structure 1012 that is integral with or secured to the outer peripheral member 1008. In one embodiment, the internal structure 1012 can be secured to an inner surface of the outer periphery member 1008 such that it is offset from front and back planar boundaries of the outer periphery member 1008. As shown in
In this embodiment, the electronic device housing 1000 also includes similar structure on an opposite side of the electronic device housing 1000. Namely, the electronic device housing 1000 can further include a second outer housing member 1016 supported and protected by a second interface member 1018. The second interface member 1018 provides protective side members 1020 (e.g., protective side bumpers) positioned tightly adjacent sides of the second outer housing member 1016. The second interface member 1018 also supports the second outer housing member 1016 and serves to secure the second outer housing member 1016 to other portions of the electronic device housing 1000. In this embodiment, the second interface member 1018 can be secured to the outer periphery member 1008 on the opposite side from the first interface member 1004. More particularly, in this embodiment, the second interface member 1018 includes second securing features 1022 (e.g., attachment arm) that are used to secure the second interface member 1018 (and thus the second outer housing member 1016) to the outer periphery member 1008. Further, a second internal space 1024 is provided internal to the electronic device housing 1000 (between the internal structure 1012 and the second interface member 1018) whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device.
In one embodiment, the first outer housing member 1002 can represent a top outer surface for the portable electronic device, and the second outer surface housing 1016 can represent a bottom outer surface housing. In one embodiment, both the first outer housing member 1002 and the second outer housing member 1016 are glass (e.g., class covers).
In
In still other embodiments, the protective side materials can be formed from multiple materials that can be alternated, intertwined or layered. The later of material against the edges of the outer housing member of glass can have a CTE relatively close to that of glass while an outer layer can have a higher CTE can permit a greater range of material, such as polymers (e.g., plastics).
The protective side members are able to be thin yet be cosmetically unintrusive. For example, in some embodiments, the thickness (t1) for the protective side member can be less than 1 mm (e.g., 0.8 mm). Also, in some embodiments, the thickness (t2) of the outer housing member can be less than 5 mm (e.g., 1 mm). However, these thicknesses are exemplary and vary with the size of the electronic device housing and with desired strength. Using a strengthened material for the protective side members as noted above can also be advantageous. Nevertheless, the provisioning of thin protective side members for outer housing members, such as glass covers, facilitates providing portable electronic device housings that are compact and thin yet resistant to side impact damage to the outer housing members.
The various members, parts or assemblies of the electronic device housing 1100 can be formed of any of a variety of materials, e.g., glass, polymer or metal. In one embodiment, the outer housing member 1102 is glass, the outer periphery member 1108 is formed from metal or polymer (e.g., plastic), and the another outer housing member 1112 is formed from glass, polymer (e.g., plastic) or metal. The interface member 1104 can be formed of a polymer or from a combination of materials. For example, the protective side members 1106 are to be strong; hence, a structurally strengthened polymer, such as polyarylamide, can be utilized. The polyarylamide can be strengthened by containing glass fibers. Also as an example, the securing features 1110 can be formed from metal for increased strength. The securing features 1110 if formed of metal can be combined with the balance of the interface member 1104 by an over-molding process.
The electronic device housing 1200 can also include an internal structure 1212 that is integral with or secured to the outer peripheral member 1208. In one embodiment, the internal structure 1212 can be secured to an inner surface of the outer periphery member 1208 such that it is offset from front and back planar boundaries of the outer periphery member 1208. As shown in
In this embodiment, the electronic device housing 1200 also includes similar structure on an opposite side of the electronic device housing 1200. Namely, the electronic device housing 1200 can further include a second outer housing member 1216 supported and protected by a second interface member 1218. The second interface member 1218 provides protective side members 1220 (e.g., protective side bumpers) positioned tightly adjacent sides of the second outer housing member 1216. The second interface member 1218 also supports the second outer housing member 1216 and serves to secure the second outer housing member 1216 to other portions of the electronic device housing 1200. In this embodiment, the second interface member 1218 can be secured to the outer periphery member 1208 on the opposite side from the first interface member 1204. More particularly, in this embodiment, the second interface member 1218 includes second securing features 1222 (e.g., attachment arms) that are used to secure the second interface member 1218 (and thus the second outer housing member 1216) to the outer periphery member 1208. Further, a second internal space 1224 is provided internal to the electronic device housing 1200 (between the internal structure 1212 and the second interface member 1218) whereby various electrical components can be attached, affixed or placed so as to provide electronic operations for the electronic device.
In one embodiment, the first outer housing member 1202 can represent a top outer surface for the portable electronic device, and the second outer surface housing 1216 can represent a bottom outer surface housing. In one embodiment, both the first outer housing member 1202 and the second outer housing member 1216 are glass (e.g., class covers).
In
After the outer glass member has been secured 1302 to the protective side member, the glass assembly can be positioned 1304 in an opening of an outer periphery member. After the glass assembly has been positioned, the glass assembly at the opening of the outer periphery member can be secured 1306. The glass assembly, namely, the outer glass member, can thus operate as an outer surface for the electronic device housing. Following the block 1306, the outer member assembly process 1300 can end.
In one embodiment, the outer glass member can represent a front (or top) surface of the electronic device housing. In another embodiment, the outer glass member can represent a back (or bottom) surface of the electronic device housing. In general, the outer member assembly process 1300 can represent processing suitable for any exposed surface of an electronic device housing that is formed of a glass member. In still another embodiment, the electronic device housing may utilize an outer glass member for a front surface of the electronic device housing and may utilize an outer glass member for a back surface of the electronic device housing.
As discussed above, such as in
In the case of portable electronic devices, housings are banged against or rub against various surfaces. When plastic or metal housing surfaces are used, the surfaces tend to become scratched. On the other hand, with glass housing surfaces (e.g., glass covers), the surfaces are much more scratch resistant. Moreover, glass housing surfaces offer radio transparency, while metal housing surfaces disturb or hinder radio communications. In one embodiment, an electronic device housing can use glass housing members (e.g., glass covers) for a front surface and a back surface of the electronic device housing. For example, a front surface formed from a glass housing member can be transparent to provide visual access to a display device positioned behind the glass housing member at the front surface, while a back surface formed from a glass housing member can be transparent or non-transparent. Non-transparency, if desired, can conceal any interior components within the electronic device housing. In one embodiment, a surface coating or film can be applied to the glass housing member to provide non-transparency or at least partial translucency. Such a surface coating or file can be provided on an inner surface or an outer surface of the glass housing member. The protective side members and the interface members discussed herein can be optionally used to protect and/or assembly the glass housing members.
Although only a single attachment device 1416 is shown for the attachment member 1408, it should be understood that several attachment devices would ordinarily be used to reliable secure the first interface assembly 1402 to the side member 1414. Likewise, although only a single attachment device 1418 is shown for the attachment member 1412, it should be understood that several attachment devices would ordinarily be used to reliable secure the second interface assembly 1404 to the side member 1414. Also, although the embodiment illustrated in
According to another aspect, apparatus, systems and methods for robustly attaching a cover portion of an electronic device to a bottom portion, e.g., a housing portion, of the electronic device are described. The cover portion may generally include a frame (e.g., interface member) into which a glass member has been inserted. Attachment members (e.g., arms, tabs) can be coupled to, e.g., insert molded into, a cover portion, and can be arranged to substantially engage with a housing portion such that the cover portion is effectively held against the housing portion. The attachment members can be used to screw or otherwise fasten the cover portion to the housing. In general, receptacles of the housing portion are arranged to substantially capture, mate or otherwise engage attachment members of the cover portion.
In one embodiment, the cover portion is held against the housing portion such that a contact surface of the cover portion interfaces with a contact surface of the housing portion, e.g., such that there is effectively no gap between the contact surfaces. More generally, the cover portion may be held against the housing portion such that the size of any space between the contact surface of the cover portion and the contact surface of the housing portion may be controlled. For example, to hold the cover portion against the housing portion, a protrusion that is a part of or is otherwise attached to the cover portion can be engaged with a receptacle that is a part of or is otherwise attached on the housing portion.
The apparatus, systems, and methods of the present invention allow for the formation of a robust coupling between a cover of a device, such as a handheld electronic device, and a housing of such a device. Handheld electronic devices may generally include, but are not limited to including, mobile phones, media players, user input devices (e.g., mouse, touch sensitive devices), personal digital assistants, remote controls, electronic book readers, etc. The apparatus, systems, and methods may also be used for covers (e.g., covers with glass members), or displays for other relatively larger form factor electronic devices such as portable computers, tablet computers, displays, monitors, televisions, etc.
In general, a device that includes a cover which is securely held to a housing is relatively durable or robust. A secure coupling between the cover and the housing may be arranged in an interior volume of a device such that the coupling does not interfere with the exterior of the device. The aesthetic qualities of a device can be enhanced. In one embodiment, a cover and a housing interface together with substantially no gap space therebetween. More generally, the aesthetic or visual qualities of a device may be substantially improved by controlling the size of a gap between a cover and a housing when the cover and the housing are assembled. In addition, when the size of a gap between a cover and a housing may be substantially minimized, the profile of a device formed from the cover and the housing may be relatively thin.
With reference to
In step 1609, a cover is formed. Forming a cover may include, but is not limited to including, obtaining a frame, and attaching a glass member to the frame. It should be appreciated that forming a cover may also include effectively attaching or otherwise creating attachment features, as for example using an injection molding process, to the cover that are configured to facilitate mounting the cover to the housing. When attachment features are attached to the cover using an insert molding process, cover can be formed at least partially from a plastic material.
Once the housing and the cover are formed, internal structural components, e.g., an internal platform that can include electronic components, can be substantially connected to the housing in step 1613. For example, an internal member may be inserted within the housing and connected to several portions of the housing to define a structural component.
After the internal structural components are substantially connected to the housing, components may be inserted in step 1617 into the housing. For example, components, such as electrical components may be inserted from both sides of the housing. The cover may then be mounted on the housing in step 1621. Mounting the cover on the housing may include, but is not limited to including, engaging attachment features of the cover and the housing. The method of assembling an electronic device can be completed once the cover is mounted on the housing.
In one embodiment, a cover may be mounted on a housing through the use of screws. Referring next to
When screws 1736 are used to secure tabs 1732 and, thus, cover 1708 to housing 1712, washers 1740 may be positioned between heads of screws 1736 and tabs 1732. Tabs 1732 are secured to housing 1712 when screws 1736 are screwed into screw receptacles (not shown) created in housing 1712. Tabs 1732, as shown, are secured to a surface of housing 1712 that is different from a surface of housing 1712 that essentially comes into contact with cover 1708.
In lieu of using screws to robustly mount a cover to a housing, other types of couplings may be used to robustly mount a cover to a housing. Another coupling that may be used to mount a cover to a housing includes a lobster snap and an internal structure (e.g., midplate).
Midplate 1952, which may be formed from metal, may be coupled to housing 1912 using any suitable method. By way of example, midplate 1952 may be welded into an interior surface of housing 1912. Referring next to
Another suitable coupling that allows a cover to be mounted on a housing is a snap arrangement that includes a bracket configured to accommodate a tab. Such a bracket may be mounted on a housing, and may include a complaint snap which is arranged to engage a tab coupled to a cover.
A compliant snap 2168 is formed in bracket 2164, and is configured to engage with tab 2160 when tab 2160 is inserted through an opening 2172, e.g., a “doghouse” snap opening,” defined by bracket 2164 and an interior surface of housing 2112. A compressive force is generally applied by compliant snap 2168 against tab 2160 to secure tab 2160 within opening 2172 and, thus, to hold cover 2108 substantially against housing 2112.
Once brackets are welded or, more generally, attached to the perimeter of the sides of the housing, tabs or hooks can be insert molded to cover support in step 2209. Then, in step 2213, a glass piece is coupled to the cover support to form an overall cover part. In one embodiment, the cover support may be a frame within which the glass piece may be secured. Any suitable method may typically be used to couple the glass piece to the cover piece.
After the overall cover part is formed, process flow moves to step 2217 in which internal components are placed within an interior volume defined within the housing. The internal components generally include, but are not limited to including, electronic components. The overall cover part is assembled against the housing in step 2221 such that the tabs in the cover piece are substantially inserted through doghouse openings in the brackets welded to the housing. When tabs are inserted through doghouse openings, complaint snaps of the brackets may engage the tabs to hold the overall cover part against the housing. Upon assembling the overall cover part against the housing such that tabs go through doghouse openings in brackets, the method of creating a device is completed.
Although only a few embodiments of the invention have been described, it should be understood that the invention may be embodied in many other specific forms without departing from the spirit or the scope of the present invention. By way of example, a cover has generally been described as being removably coupled to a housing. Screws may be unscrewed to remove a cover from a housing, snaps may be disengaged from a midplate, and tabs may be disengaged from a snap. The ability to substantially disengage or decouple a cover from a housing may enable maintenance and repairs to be performed on components held by the housing. In some embodiments, however, cover may be substantially irremovably coupled to a housing.
While a cover has generally been described as including a cover support (e.g., frame) to which a glass member is attached, it should be appreciated that the cover itself may be a glass member. In an embodiment in which the cover itself is a glass member, attachment features such as tabs and snaps may be glued directly to the glass member or indirectly to the glass member. When attachment features are glued indirectly to the glass member, the attachment features may be insert molded into pieces of plastic, and the pieces of plastic may be glued or otherwise attached to the glass member.
As shown for example in
Any number of coupling arrangements that allow a cover to be mounted to a housing may generally be included in an electronic device. Coupling arrangements are generally arranged along an interior periphery of an electronic device, and the number of coupling arrangements in an electronic device may be dependent upon factors including, but not limited to including, the size of the electronic device and the space available in the interior of the electronic device. In one embodiment, between approximately ten and approximately twenty coupling arrangements may be included in an electronic device. It should be appreciated, however, that fewer than ten and more than twenty coupling arrangements may generally be included in an electronic device.
According to still another aspect, an optical lens can be formed from a formed optical adhesive. The optical lens can, for example, be used as a lens for a camera flash of a portable electronic device. A mold can be used to form a lens from an optical adhesive that can be cured while being molded. For example, the optical adhesive can be a liquid adhesive that can be cured by ultraviolet (UV) radiation. In one embodiment, a mold (e.g., steel mold) having a lens configuration can be applied to the uncured optical adhesive, and then UV radiation applied to cure the optical adhesive. Once cured, the mold can be removed and the optical lens has been formed. In one particular embodiment, the optical lens can be formed on an inner surface of a glass housing member for a portable electronic device, and the curing of the optical adhesive to form the optical lens can be performed by UV radiation that is directed to the optical adhesive through the glass housing member. In another particular embodiment, the optical lens can be formed on an optical substrate (e.g., clear plastic carrier), and then the optical substrate can later be mounted in a portable electronic device, such as on an inner surface of a glass housing member for the portable electronic device.
In one embodiment, the portable electronic device having the optical lens formed from the optical adhesive can be configured to include a housing surface that has at least an opening or transparent portion. The portable electronic device can also include a camera and a camera flash light element for producing light. The optical lens receives at least a portion of light produced by the camera flash light element, and directs the received light through the opening or transparent portion of the housing surface. The optical lens can be formed from an optical adhesive that is molded and cured into a predetermined lens configuration.
According to still another aspect, a cover assembly, such as a back cover assembly, can be configured to support and protect an outer glass member. The cover assembly can form part of a housing for an electronic device. The cover assembly can also include a distinct glass lens, attachment members, and structural support.
The back cover assembly 2300 can be secured to the base housing in any of a variety of ways. In the embodiment of the interface member 2302 illustrated in
The glass member 2304 is a thin glass sheet that is configured to fit within a recess provided by the interface member 2302. In one embodiment, while within the recess, the sides (e.g., edges) of the glass member 2304 can be protected by protective side structural members. A glass piece 2310 and an optical barrier 2312 can be coupled to the glass member 2304. The glass piece 2310 can be provided for an image acquisition device (e.g., camera) that is provided within the base housing for the electronic device. The glass piece 2310 is separate from the glass member 2304. The glass piece 2310 can also provide different optical properties than those of the glass member 2304. For example, the glass piece 2310 may (itself or via a coating) provide optical filtering (e.g., infrared filtering) or magnification. In other words, the glass piece 2310 can act as a lens, a filter or both.
The size, dimensions and materials for the components of the housing for the electronic device can vary with different embodiments. In the case of portable electronic devices, the thickness of the back cover assembly 2300 (excluding the one or more tabs 2306 and the one or more hooks 2308) can be about 5 millimeters or less. For thin, portable electronic devices (such as handheld electronic devices), the thickness of the back cover assembly 2300 (excluding the one or more tabs 2306 and the one or more hooks 2308) can be about 2 millimeters or less millimeters. Moreover, the thickness of the glass member 2304 can be about 1 millimeter or less. For example, the thickness of the glass of the glass member 2304 can be about 0.3 to 0.6 micrometers. The glass member 2304 is glass (e.g., alumina silicate or soda lime glass). However, in alternative embodiments, the glass member 2304 could be replaced by a member that is made (in whole or in part) of metal, ceramic and/or plastic material.
Additionally, a back cover assembly can also include one or more features to facilitate image acquisition. In one embodiment, the back cover assembly 2300 can also include an opening 2322 in the interface member 2302 for image acquisition components.
