The present invention relates to a docking station for an electronic device. More particularly, the present invention relates to a docking station having a compliant connector mount that is more durable and flexible.
Portable electronic devices (such as phones, media players, notebook/netbook computers, tablet computers) are becoming ubiquitous in today's society. Portable electronic devices commonly have display screens (e.g. a touch screen) on which users view and/or select data and functionality. For example, a user may select a video or other presentation to watch. In such circumstances, it is more convenient for the user to have the device in an upright (viewable) position by placing the device in some sort of holder so the user is not forced to hold the device during viewing.
Additionally, users would like to interface the display devices with other electronics. For example, a user may want to play music through speakers, or simply charge the device. However, during such interfacing or charging, the user would still like to be able to view the display and/or controls of the device.
To provide such features, manufacturers provide docking stations (docks) in which a user can plug the device. Often the docks will have a connector rising out from a surface, with the connector being in a position such that the device can be viewed and/or used. However, connectors can be weak points, especially when devices become large and additional stresses are placed on the connector, particularly in connectors of relatively small size. The connector may also provide most of the support of the device. Accordingly, the connectors of such docking stations can be damaged by misuse, e.g. being pulled in improper direction.
Embodiments of the present invention provide docking stations having a connector with a compliant mount that is more flexible and durable. Some embodiments allow the connector to move when connected to a portable electronic device. This movement of the connector can absorb undesirable forces, thereby reducing a likelihood of the connector breaking from misuse. Examples of movement include sliding, translation, flexures, rotation and/or some combination thereof. For example, in some embodiments, if the portable electronic device is pushed forward, the connector can rotate, thereby reducing the likelihood of breakage from such a push.
In one aspect, the invention provides a mount configured to flex when the connector is stressed so as to pivot the connector at a projected or virtual pivot point a distance away from where the flexure occurs. In some embodiments, the mount is configured to provide at least two flexures or flexure hinges so that the flexural movement of the at least two flexures, in combination, pivots the connector about the virtual or projected pivot point, the pivot point being disposed a distance away from either point of flexure. The flexures of the compliant mount may also be configured to provide sufficient rigidity to the connector to support a portable device when mounted on the connector within the dock in an upright position, sufficient flexibility to allow angular displacement of a mounted portable device, and sufficient elasticity to provide a resilient biasing force to return a mounted portable device from a displaced position to the upright position. The flexures may be configured to provide controlled movement within a desired range of movement. For example, the flexures may allow a portable device mounted on the connector to tilt forward from a non-stressed mounted plane with increasing resistance to a maximum angular displacement within a range of 90 degrees or less, or in some embodiments, 45 degrees to 10 degrees. The flexures may be configured to distribute and absorb stresses associated with displacement of the connector, thereby reducing the likelihood of damage to the devices or associated connectors.
In another aspect, the compliant mount may be configured with a bias toward a particular position, such as an upright position, such that the electronic device is supported by the compliant mount (or alternatively by a rear reference surface of the docking station), thereby preventing undue strain on the rotatable connector in the non-deflected position. The bias of the compliant mount can be controlled by the shape and material properties of the compliant mount. For example, in some embodiments, the compliant mount is configured to support the connector in an upright position that is tilted back slightly, when the compliant mount is unstressed and unflexed so as to facilitate viewing or operation of the portable device by a user when mounted in the dock. The connector may be disposed partly below and partly above an outer shell of a base of the docking station, and pivot at a location on the connector near an opening in the outer shell of the dock base through which the connector protrudes, thereby reducing movement of the connector near the opening. This aspect allows the opening in the housing to be minimized, and reduces the likelihood of interference between the connector and the docking housing as the connector pivots.
According to one embodiment, a docking station can include a base, a rear reference surface for at least partly supporting a portable electronic device in the upright position, and a movable connector that is configured to receive and electrically couple to a receptacle connector of the portable device. The movable connector can be coupled to the base by a compliant mount and biased toward the upright position. The rear reference surface can be mechanically coupled to the base and adapted to support the portable electronic device when the electronic device is coupled to the rotatable connector in its upright position. The compliant mount may include one or more flexures or flexure hinges to provide pivotal movement of the connector. In some embodiments, the compliant mount includes at least two flexure hinges so that the flexural movements, in combination, move the connector about a virtual pivot point a distance away from either point of flexure. In other embodiments, the compliant mount includes three or more flexure hinges, so that overlapping of the range of movement associate with flexure occurs at a desired pivot point location, such as near where the connector protrudes from an opening in a housing of a device, such as a docking station.
In some embodiments, the compliant mount includes at least two flexure hinges and one or both of at least two flexure hinges includes a series of undulations, such as a series of S-shaped or sinusoidal curves, to provide increased flexibility and elasticity to the compliant mount. A flexure hinge may also include a thinned plate having a plurality of opening, such as a series of elongate opening therein, so as to allow flexure of the plate, or a cantilever hinge. The at least two flexure hinges may be configured in series, in parallel or any combination so that the combined flexure movement of the at least two flexure hinges provides a desired movement of a connector attached thereto. Although various types and configures of flexure hinges are described herein, it is appreciated the flexure hinges of a compliant mount may include hinges of the same or differing types and configuration, including any combination of configurations or types of flexures.
Embodiments of the present invention provide a docking station (dock) having a connector with a compliant mount that allows for improved durability, flexibility and control of movement of the connector. These objectives can be accomplished, in part, by allowing the connector to move so that the connected portable electronic device does not put a significant amount of force on the connector. For example, with limited reference surfaces (surfaces that can touch the electronic device when it is connected with the connector), a joint of a fixed connector may weaken if the portable electronic device is forced off its attachment/detachment axis. Such a force may occur inadvertently when a user reaches for the device. The force of the push and/or the force of the weight of the device, which may weaken the joint, instead simply moves the connector.
In one aspect, the connector may be configured to move or pivot relative to the dock base in order to better distribute the forces when an off axis force is applied, e.g., it moves with the force rather than completely resisting the force by not moving. In some embodiments, the connector is attached to the dock base through a compliant mount of which flexure allows the connector attached thereto to pivot about a projected or virtual pivot point from an upright position to an angularly displaced or tilted position, thereby accommodating a force applied to the connector through a portable device mounted in the docking station. The compliant mount may be configured with a bias towards a natural position in which the connector is supported upright, the bias providing a resilient force when displaced so as to inhibit forward tilt movement of the portable device beyond a maximum angular displacement and to resiliently return the connector to the upright position when the applied force is removed. The precise motion of the connector and forces from any biasing mechanism can be tuned to provide a desired motion and feel when a user moves the electronic device.
As used herein, a portable electronic device is of such size and proportion that it may be carried in the hand(s) of a person. Examples of portable electronic devices include but are not limited to media players that play or otherwise transmit audio and/or visual (video or picture) signals (e.g., iPod) and phones that allow users to communicate remotely through wireless connections. Portable electronic devices may also correspond to mini-computers, tablet computers, PDAs, internet or email based devices. In fact, portable electronic devices may be a combination of specific or dedicated devices mentioned above (e.g., a smart phone such as the iPhone™), manufactured and sold by Apple Inc. of Cupertino, Calif., the assignee of the present application.
Embodiments of the invention are discussed below with reference to figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes as the invention extends beyond these embodiments. For example, embodiments may be used with various types of connectors between device, including non-portable devices.
Docking stations may be a stand-alone unit that communicates with other devices or systems through wired (e.g., cables) or wireless (e.g., Bluetooth) connections, or alternatively, a docking station may be integrated directly into the other devices or systems. In one embodiment, connector 110 may be connected to other electronics housed within the docking station via a flexible or movably-enabled connection, such as swiping contacts, wires, traces, flexible circuits and/or the like. Some of these examples may include slack so that the connector can move between positions. The electronics may be widely varied. The electronics may for example include circuit boards, controllers, connectors, and the like. The electronics can be fixed within the body or configured to be movable to help manage the connection between the electronics and connector 110, as connector 110 moves. For example, a printed circuit board may slide along rails. Certain embodiments are described in more detail below.
Docking station 300 can also hold electronic device 200 in a position suitable for viewing a display 213 of the electronic device. Docking station 300 may include a base, which may contain various electronics, ballast, and the like. The base can serve to keep docking station 300 balanced and supported on a surface such as a table, as well as keep electronic device 200 balanced and supported when mounted thereto. Docking station 300 may also provide one or more reference surfaces for helping support the electronic device in an upright position.
Connector 110 may be coupled to other connectors, ports, jacks, transceivers, or cables of the docking station, thereby providing external connections to the other devices or systems. In the case of an integrated docking station, connector 110 may be wired directly to the components of the host device or system. In some cases, connector 110 is substantially on its own while in other cases the connector may be part of a module that includes a secondary structure, such as a housing.
In various embodiments, connector 110 can correspond to USB, Firewire, or other standardized connector formats. In one example, connector 110 is an 8-pin connector compatible with the Apple iPod® and iPhone™ devices. In an embodiment, the 8-pin connector has a thin low profile (as shown) with spaced apart side by side pins, which may be in a single row. In one embodiment, the electronic device can have a female connector receptacle connector that connects with connector 110, which may be a male connector plug. In alternative embodiments, the electronic device can have a male connector receptacle that connects with a female connector plug of a dock. In this embodiment, the female receptacle may be situated in a housing.
In one embodiment, an insertable tab of connector 110 protrudes through an opening 330 in an outer housing 310 of the docking station 300, the insertable tab portion 114 having a plurality of electrical contacts 122 disposed thereon being exposed and substantially free from external walls and surfaces (e.g. no or limited walls that surround or are adjacent to the connector) to facilitate mating engagement within the corresponding receptacle 210 of the portable device 200. As such, connector 110 may be configured to support electronic devices coupled thereto via a corresponding mating connector with limited or no reference surfaces provided for the electronic device. While in various embodiments connector 110 protrudes from an opening 330 within a docking well 320 of a dock 300, connector 110 need not be disposed within a recess or cavity and instead may extend outward from a surface such that its sides are exposed. As shown in
Because connector 110 can be exposed and substantially free from reference surfaces, undesirable off-axis forces may be exerted on connector 110 especially when an electronic device is connected thereon. For example, during a removal event, the electronic device may be rotated, pushed, pulled away from the mating axis thereby imparting undesirable forces on connector 110. By way of example, if mating axis 130 is in the direction of the z axis, undesirable forces may be imparted on the connector by translating the electronic device in x and y as well as rotations about x, y and z axes. In addition, there may even be some forces pulling/pushing on the connector along the z axis due to friction between the mating connectors. Certain configurations of connector 110 may lead to more susceptible areas of undesirable forces.
Of particular concern, are torques and bending stresses that may be applied to connector 110 through manual articulation of a portable device 200 mounted thereon, such as shown in
In one aspect, to achieve the above noted objectives, the connector 110 is attached to a base of the dock 300 by a compliant mount 100 that allows for movement of the connector 110 at a virtual pivot point relative to the base at or near where the connector 110 protrudes from a housing of the dock 300 by providing flexural movement a distance below the virtual pivot point. By projecting the pivot point a distance away from the flexure that provide for the pivotal movement, the compliant mount 100 can avoid interference with the housing of the dock. The compliant mount 100 may also be configured to allow for movement of the connector 100 about a pivotal axis substantially parallel to the x-axis, such as shown by the arrow in
In the embodiment of
Coupling the base of the connector 110 to a connector plate 107 having a width greater than a width of the connector 110 allows the compliant mount to distribute forces applied through the connector 110 over a greater distance so as to provide improved resistance to rotational forces about each of the x, y and z-axes. In addition, distributing the forces over a first and second flexure hinge having a width along the x-axes greater than that of the connector 110 assists in reducing the stresses to allow the flexure of the hinges to remain below plastic deformation so that the flexure hinges can accommodate flexural movement while still maintain sufficient elasticity to provide a resilient bias towards the upright position.
FIGS. 10 and 11A-11C shows a cut-away view of alternative example of a connector and compliant mount within a docking station. Similar to the embodiment in
It is appreciated that although in various embodiments the compliant mount is described as including at least a first and second flexure or flexure hinge, the complaint mount is not so limited and may include additional flexure hinges or varying combinations of flexure hinges, as desired, to provide additional flexibility or improved control over the movement of the connector relative to the dock. The specific details of particular embodiments may be combined in any suitable manner or varied from those shown and described herein without departing from the spirit and scope of embodiments of the invention. Moreover, the invention may also provide other features of docking stations, such as speakers, a video screen computers, and charging mechanisms.
The above description of exemplary embodiments of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form described, and many modifications and variations are possible in light of the teaching above. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications to thereby enable others skilled in the art to best utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated.
