Mobile computing devices have been developed to increase the functionality that is made available to users in a mobile setting. For example, a user may interact with a mobile phone, tablet computer, or other mobile computing device to check email, surf the web, compose texts, interact with applications, and so on.
Because mobile computing devices are configured to be mobile, the devices are typically designed to be used in a handheld manner. Traditional ways of adapting mobile devices for other uses (e.g., on a table or other surface) tend to be awkward and detract from the mobile aesthetic associated with mobile devices.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
A hinge mechanism with multiple preset positions is described. According to various embodiments, the hinge mechanism enables a support component to be adjustably attached to an apparatus, such as a computing device. In at least some embodiments, the hinge mechanism utilizes preset hinge positions that enable the support component to be placed at different preset positions. For instance, the hinge mechanism is configured such that an attached support component tends to “snap” into various preset positions. In at least some embodiments, the hinge mechanism includes an emergency escape position that enables the support component to be rotated beyond normal operating positions without damaging the support component.

Overview
A hinge mechanism with multiple preset positions is described. In at least some implementations, the hinge mechanism enables a support component to be adjustably attached to an apparatus, such as a computing device. For example, the hinge mechanism can be employed to rotatably attach a kickstand to a mobile computing device. The kickstand can be rotated via the hinge mechanism to various positions to provide support for different orientations of the computing device. For example, the kickstand can be positioned to support the computing device in a typing orientation such that input can be provided via an associated input device. As another example, the kickstand can be positioned to enable viewing and/or interaction with the computing device, such as in a portrait viewing orientation.
In at least some implementations, a hinge mechanism utilizes preset hinge positions that enable a kickstand to be placed at different preset positions. Further, the hinge mechanism includes a center of rotation that is external to the hinge mechanism. Thus, the kickstand can conform to a contour of the computing device when in a closed position, and maintain a minimal external profile when moving between the different preset positions. According to various implementations, the hinge mechanism includes an emergency escape position that enables the kickstand to be rotated beyond normal operating positions without damaging the kickstand or detaching the kickstand from an associated device.
In at least some implementations, the hinge mechanism discussed herein is configured such that an attached support component tends to “snap” into various preset positions. Generally, snapping refers to movement of the hinge mechanism in response to force generated internally to the hinge mechanism, e.g., via a hinge spring and/or other component that provides elastic force for the hinge mechanism. In at least some implementations, snapping occurs when a user releases a support component, e.g., independent of user-applied force to the support component. For instance, torque forces that apply during movement of the hinge mechanism are such that the hinge mechanism typically does not rest at positions outside of the preset positions unless held there by a user. Thus, torque forces at work during movement of an attached support component provide a form of tactile feedback that indicates to a user whether the support component is positioned in a normal operating position, e.g., at a preset position for the hinge mechanism. Various attributes and components of example hinge mechanisms are presented in detail below.
In the following discussion, an example environment is first described that may employ the techniques described herein.

Next, example hinges for kickstand attachment are discussed in accordance with one or more embodiments. Following this, a section entitled “Hinge Responsiveness Profile” discusses an example torque profile for hinge movement in accordance with one or more embodiments. Finally, an example system and device are discussed that may implement various techniques described herein.
Example Environment
While embodiments presented herein are discussed in the context of a tablet device, it is to be appreciated that various other types and form factors of devices may be utilized in accordance with the claimed embodiments. Thus, the computing device 102 may range from full resource devices with substantial memory and processor resources, to a low-resource device with limited memory and/or processing resources. An example implementation of the computing device 102 is discussed below with reference to
The computing device 102 is illustrated as including an input/output module 108, which is representative of functionality relating to processing of inputs and rendering outputs of the computing device 102. A variety of different inputs may be processed by the input/output module 108, such as inputs relating to functions that correspond to keys of the input device 104, keys of a virtual keyboard displayed by the display device 110 to identify touch gestures and cause operations to be performed that correspond to the touch gestures that may be recognized through the input device 104 and/or touchscreen functionality of the display device 110, and so forth. Thus, the input/output module 108 may support a variety of different input techniques by recognizing and leveraging a division between types of inputs including key presses, touch gestures, touchless gestures recognized via a camera functionality of the computing device 102, and so on.
In the illustrated example, the input device 104 is configured as having an input portion that includes a keyboard having a QWERTY arrangement of keys and track pad although other arrangements of keys are also contemplated. Further, other non-conventional configurations are also contemplated, such as a game controller, configuration to mimic a musical instrument, and so forth. Thus, the input device 104 and keys incorporated by the input device 104 may assume a variety of different configurations to support a variety of different functionality.
As previously described, the input device 104 is physically and communicatively coupled to the computing device 102 in this example through use of a flexible hinge 106. The flexible hinge 106 is flexible in that rotational movement supported by the hinge is achieved through flexing (e.g., bending) of the material forming the hinge as opposed to mechanical rotation as supported by a pin, although that embodiment is also contemplated. Further, this flexible rotation may be configured to support movement in one or more directions (e.g., vertically in the figure) yet restrict movement in other directions, such as lateral movement of the input device 104 in relation to the computing device 102. This may be used to support consistent alignment of the input device 104 in relation to the computing device 102, such as to align sensors used to change power states, application states, and so on.
Example Device Orientations
According to various embodiments, a variety of different orientations of the computing device 102 are supported. For example, rotational movement may be supported by the flexible hinge 106 such that the input device 104 may be placed against the display device 110 of the computing device 102 and thereby act as a cover as shown in the example orientation 200 of
As shown in the example orientation 300 of
Naturally, a variety of other orientations other than those expressly illustrated and discussed herein are also supported.
Kickstand
The described kickstand can be employed as a support component to enable a variety of different orientations for the computing device 102. For instance, consider the following implementations of a kickstand in accordance with various embodiments.
In at least some implementations, the position 500 corresponds to a preset position for the kickstand 302. For instance, when a user applies pressure to the kickstand 302 away from the rear surface 402, the kickstand 302 can snap into the position 500. As detailed below, a hinge mechanism employed to attach the kickstand 302 to the computing device 102 can utilize spring pressure and detent settings to provide preset open positions for the kickstand 302. In this example, the position 500 is associated with an angle 504 between the rear surface of the computing device 102 and the kickstand 302. For instance, the angle 504 can range from 45 degrees (45°) to 55 degrees (55°). The angle 504, for example, is approximately 48°, +/−3°. Any suitable angle and/or range of angles may be employed, however.
According to various implementations, the position 500 places the front surface of the display device 110 at an angle 506 relative to a vertical line 508. The vertical line 508, for instance, is normal (i.e., 90°) to a surface 510 on which the computing device 102 and the kickstand 302 are disposed. In this particular example, the angle 506 is approximately 24°, +/−3°. The angle 506, for instance, is one-half of the angle 504.
As illustrated, the input device 104 can be rotated away from the computing device 102 and supported by the kickstand 302. The position 500, for instance, enables the display device 110 to be viewed and input to be provided to the computing device 102 via the input device 104. Alternatively or additionally, the position 500 enables a user to interact with a touchscreen of the computing device 102.
In at least some implementations, the position 600 corresponds to a further preset position for the kickstand 302. For example, when a user applies pressure to the kickstand 302 away from the rear surface 402 (e.g., past the position 500), the kickstand 302 can snap into the position 600. In this example, the position 600 is associated with an angle 602 between the rear surface of the computing device 102 and the kickstand 302. For instance, the angle 602 can range from 80 degrees (80°) to 85 degrees (90°). The angle 602, for example, is approximately 84°, +/−4°. Any suitable angle and/or range of angles may be employed, however. Further, the seam 502 can be maintained (e.g., the width of the seam) during rotation to the position 600.
With the kickstand 302 in the position 600, the computing device 102 supports a variety of different usage scenarios. For instance, consider the following two example scenarios.
According to various implementations, the orientation 700 places the front surface of the display device 110 at an angle 702 relative to a vertical line 704. The vertical line 704, for instance, is normal (i.e., 90°) to a surface 706 on which the computing device 102 and the kickstand 302 are disposed. In this particular example, the angle 702 is approximately 42°, +/−5°. The angle 702, for instance, is one-half of the angle 602.
With the kickstand 302 in the position 600, the computing device 102 can also be rotated sideways (e.g., to a portrait viewing position) and supported via the kickstand 302. For instance, consider an orientation 708 illustrated in
In
When separate from the input device 104, the computing device 102 can provide various functionality. For example, a user can view content via the computing device 102, such as movies and/or streaming content. Further, a user can interact with touch screen functionality of the display device 110.
Thus, placing the kickstand 302 in the position 600 can enable a user to place the computing device in a landscape and/or portrait orientation, and to view and/or interact with the computing device in such orientations.
In at least some implementations, the position 800 corresponds to a further preset position for the kickstand 302. For example, when a user applies pressure to the kickstand 302 away from the rear surface 402 (e.g., past the position 600), the kickstand 302 can snap into the position 800. In this example, the position 800 is associated with an angle 802 between the rear surface of the computing device 102 and the kickstand 302. For instance, the angle 802 can range from 113 degrees (113°) to 123 degrees (123°). The angle 602, for example, is approximately 118, +/−5°. Any suitable angle and/or range of angles may be employed, however.
According to various implementations, the position 800 places the front surface of the display device 110 at an angle 804 relative to a vertical line 806. The vertical line 806, for instance, is normal (i.e., 90°) to a surface 808 on which the computing device 102 and the kickstand 302 are disposed. In this particular example, the angle 804 is approximately 59°, +/−5°. The angle 804, for instance, is one-half of the angle 802.
Hinges for Component Attachment
A variety of different hinge mechanisms can be employed for attaching various components in accordance with various embodiments. Some example hinge mechanisms and hinge arrangements are discussed below.
The kickstand 302 can be attached to a pivoting portion of the hinges 1002a, 1002b via the hinge mounts 902a, 902b, discussed above with reference to
Components of the hinge 1100 include a hinge frame 1102 in which various other components of the hinge 1100 can be disposed. For example, the hinge frame 1102 can be mounted to and/or within a device (e.g., the computing device 102) and function as a support structure for other components of the hinge 1100.
Further included are a cam 1104, a cam follower 1106, a support plate 1108a, and a support plate 1108b. As detailed elsewhere herein, interaction between the cam 1104 and the cam follower 1106 within the hinge 1100 provides a particular responsiveness profile during user manipulation of a component attached to the hinge 1100, e.g., the kickstand 302. Further, the support plates 1108a, 1108b provide lateral support for the hinge 1100 in various open positions and enable the hinge 1100 to be positioned in various open positions. For purpose of discussion herein, the support plates 1108a, 1108b may be referred to as a support plate 1108.
The hinge 1100 also includes a hinge spring 1110, which applies pressure to the cam follower 1106 when the various components are placed in their respective positions within the hinge frame 1102. Further details concerning components and functionality of the hinge 1100 are now discussed.
The hinge frame 1102 further includes a cam follower mount 1202 into which the cam follower 1106 can be mounted. While not expressly illustrated here, the cam follower mount 1202 includes a similar portion on the opposite inside surface of the hinge frame 1102, thus forming a cradle into which a mounting portion of the cam follower 1106 can be attached.
Plate guides 1204a, 1204b represent raised portions on the inside surface of the hinge frame 1102 which are employed for mounting the support plates 1108a, 1108b into the hinge frame 1102. For instance, the plate guides 1204a, 1204b represent raised portions (e.g., curved rails) that are mirror images of one another on opposite inside surfaces of the hinge frame 1102. Generally, the support plates 1108a, 1108b engage with the plate guides 1204a, 1204b to hold the support plates 1108a, 1108b within the hinge frame 1102. During movement of a component attached to the hinge 1100 between one or more open positions, the plate guides 1204a, 1204b cause rotational movement of the support plates 1108a, 1108b. As further illustrated herein, rotational movement of the support plates 1108a, 1108b enables an attached component to be positioned in various different positions.
The hinge frame 1102 further includes a spring mount 1206, which represents a surface onto which the hinge spring 1110 is placed. As further detailed elsewhere herein, placement of the hinge spring 1110 onto the spring mount 1206 enables the hinge spring 1110 to exert pressure upon the cam follower 1106. Spring pressure on the cam follower 1106 holds the cam follower against the cam 1104 and thus enables the cam 1104 to be held in various preset positions.
An outer surface 1304 of the support plate 1108b includes a support channel 1306 that engages with the plate guide 1204b of the hinge frame 1102, introduced above. For instance, the dimensions of the support channel 1306 are such that the plate guide 1204b fits within the support channel 1306 when the support plate 1108b is mounted within the hinge frame 1102. During movement of the support plate 1108b relative to the hinge frame 1102, the support channel 1306 slides relative to the plate guide 1204b to enable rotational movement of the support plate 1108b relative to the hinge frame 1102. Although not illustrated here, an outer surface of the support plate 1108a similarly includes a respective plate channel 1306 that engages with the plate guide 1204a of the hinge frame 1102. Further features of the support plates 1108 are discussed below.
The outer cam surfaces 1402a, 1402b are positioned on either side of the inner cam surface 1400 and protrude above the inner cam surface 1400. According to various implementations, the outer cam surfaces 1402a, 1402b are mirror images of one another, and may be referred to herein as an outer cam surface 1402. As further detailed below, the inner cam surface 1400 and the outer cam surfaces 1402a, 1402b have specific surface profiles that interact with the cam follower 1106 to provide a particular response profile during movement of an attached component.
The cam 1104 further includes a cam channel 1404 and a component mounting portion 1406. The cam channel 1404 is formed such that when the cam 1104 is mounted within the hinge frame 1102 relative to the support plates 1108, the cam channel 1404 engages with the cam guide 1302 of the support plate 1108. Although not illustrated here, the opposite side of the cam 1104 includes a respective cam channel 1404. The dimensions of the cam guide 1302 of the support plate 1108, for instance, are such that the cam guide 1302 fits within the cam channel 1404. During movement of the cam 1104 relative to the hinge frame 1102, the cam channel 1404 slides relative to the cam guide 1302 to enable rotational movement of the cam 1104 relative to the support plates 1108a, 1108b.
The component mounting surface 1406 is representative of a portion of the cam 1104 to which a component (e.g., the kickstand 302) can be mounted. For instance, the component mounting surface 1406 includes surface attributes that engage and/or interlock with a component to stabilize the component relative to the cam 1104. Alternatively or additionally, the component mounting surface 1406 may include one or more apertures through which a fastening device such as a screw or bolt may be placed to fasten the hinge to a component.
The top surface 1500 of the cam follower 1106 further includes a spring platform 1504 which is configured to engage with the hinge spring 1110. For example, spring tension from the hinge spring 1110 against the spring platform 1504 holds the cam follower 1106 against the cam 1104. Thus, spring tension against the cam follower 1106 results in a reaction at the cam 1104 that provides a torque response at the cam 1104. As discussed herein, the torque response results at least in part from the shape of the cam 1104 and the cam follower 1106, and the interaction between their respective surfaces.
For instance, depending on the angular position of the cam 1104 and the direction of motion, movement of the cam 1104 may be either resisted (e.g., opposed) or driven. This interaction between the different elements of the hinge 1100 provides for a “snappy” response of an attached component, e.g., the kickstand 302.
The bottom surface 1600 further includes an inner follower surface 1602 and outer follower surfaces 1604a, 1604b. For purpose of discussion, the outer follower surfaces 1604a, 1604b may be referred to as an outer follower surface 1604. The inner follower surface 1602 protrudes from the bottom surface 1600 relative to the outer follower surfaces 1604a, 1604b. As detailed elsewhere herein, the inner follower surface 1602 and the outer follower surfaces 1604a, 1604b interact with surfaces of the cam 1104 to provide a particular torque response for a component attached to the hinge 1100.
In the section view 1802, the cam 1104 is sectioned lengthwise down the center, and thus the illustrated section of the cam 1104 illustrates a surface profile of the inner cam surface 1400, introduced above. The cam follower 1106 is also sectioned lengthwise down the center, and thus the illustrated section of the cam follower 1106 illustrates a surface profile of the inner follower surface 1602.
In the position 1800, force applied by the hinge spring 1110 holds the cam follower 1106 against the cam 1104. Further, the interface between the cam follower 1106 and the cam 1104 is such that movement of the kickstand 302 is resisted. For instance, the inner follower surface 1602 presses against an inner cam contact 1804, and the hinge spring 1110 resists rotational movement of the cam follower 1106 on the follower pivot 1502. Thus, absent force applied by a user to the kickstand 302, pressure from the cam follower 1106 against the cam 1104 holds the kickstand 302 in a closed position against the computing device 102.
Illustrated as part of the section view 1902 are the outer follower surface 1604 of the cam follower 1106, and the outer cam surface 1402 of the cam 1104. As illustrated, in the position 1800 (e.g., a closed position), the outer follower surface 1604 does not contact the outer cam surface 1402.
According to various implementations, movement of the kickstand 302 from the position 1800 to the position 2000 is initially resisted by pressure from the inner follower surface 1602 against the inner cam contact 1804. However, when movement of the inner cam contact 1804 proceeds past an inner follower point 2004, pressure from the inner follower surface 1602 against the inner cam contact 1804 drives the cam 1104 to the position 2000. For instance, if a user begins opening the kickstand 302 from the position 1800 but releases the kickstand 302 before the inner cam contact 1804 proceeds past the inner follower point 2004, the cam 1104 and thus the kickstand 302 will snap back into a closed position, e.g., the position 1800.
However, if the user manipulates the kickstand 302 such that the inner cam contact 1804 proceeds past the inner follower point 2004, pressure from the cam follower 1106 against the cam 1104 drives the cam 1104 into the position 2000, e.g., a first open position. For instance, if the user releases the kickstand 302 after the inner cam contact 1804 proceeds past the inner follower point 2004, the cam 1104 (and thus the kickstand 302) will snap into the position 2000.
According to various implementations, the hinge 1100 has a center of rotation 2006 this is external to the hinge itself. For instance, the center of rotation 2006 substantially coincides with the seam 502 between the kickstand 302 and stationary portions of the rear surface 402 of the computing device 102. Further, in at least some implementations, the center of rotation 2006 is consistent (e.g., does not change) when the hinge 1100 is repositioned among the various preset open positions discussed herein. This enables the kickstand 302 to maintain a consistent rotational profile and causes a width of the seam 502 to remain substantially consistent (e.g., within +/−0.050 millimeters) during rotation of the kickstand 302 among the different preset positions discussed herein.
Illustrated in the section view 2100 is the outer cam surface 1402 of the cam 1104 and the outer follower surface 1604 of the cam follower 1106. Further illustrated is that a first cam catch 2102 on the outer cam surface 1402 engages with a first follower catch 2104 on the outer follower surface 1604. Generally, the first cam catch 2102 and the first follower catch 2104 represent surface features on the outer cam surface 1402 and the outer follower surface 1604, respectively.
According to various implementations, engagement of the first cam catch 2102 with the first follower catch 2104 enables the kickstand 302 to persist in the position 2000. For instance, spring pressure from the hinge spring 1110 holds the first cam catch 2102 against the first follower catch 2104. In at least some implementations, absent external force directly and/or indirectly applied to the kickstand 302, the first cam catch 2102 will not disengage from the first follower catch 2104.
For example, the hinge 1100 is constructed such that unless a specified threshold force is applied to the kickstand 302, the hinge 1100 will not disengage from the position 2000. In at least some implementations, exceeding a threshold closing force against the kickstand 302 in one direction closes the kickstand, and exceeding a threshold opening force against the kickstand 302 in another direction opens the kickstand 302 further past the position 2000.
According to one or more implementations, contact between the cam 1104 and the cam follower 1106 occurs between the inner cam surface 1400 and the inner follower surface 1602 when the hinge 1100 is in a position from the closed position 1800 and up to the open position 2000. For instance, for a kickstand angle range of 0 degrees (e.g., position 1800) up to the position 2000, the outer cam surface 1402 does not contact the outer follower surface 1604.
However, starting with the position 2000 and continuing to further open positions such as those discussed below, contact between the cam 1104 and the cam follower 1106 transitions to the outer cam surface 1402 and the outer follower surface 1604. In these further open positions, for example, the inner cam surface 1400 is positioned away from and does not contact the inner follower surface 1602. Thus, as detailed herein, responsiveness of the hinge 1100 between at least some positions changes based on surface profiles of the different cam and cam follower surfaces, and also based on which surfaces are engaged at a particular position.
While the discussion herein is presented with reference to a particular outer follower surface 1604 and a particular outer cam surface 1402, it is to be appreciated that according to various implementations, similar features and interactions apply to the other outer follower surface and outer cam surface.
According to various implementations, movement of the kickstand 302 from the position 2000 to the position 2300 is initially resisted by pressure from the first follower catch 2104 against the first cam catch 2102. However, when movement of the first cam catch 2102 proceeds past an outer follower point 2304, pressure from the outer follower surface 1604 against the first cam catch 2102 drives the cam 1104 to the position 2300. In the position 2300, the first cam catch 2102 engages with a second follower catch 2306.
For instance, if a user begins opening the kickstand 302 further past the position 2000 but releases the kickstand 302 before the first cam catch 2102 proceeds past the outer follower point 2304, the cam 1104 and thus the kickstand 302 will snap back into the position 2000. However, when movement of the kickstand 302 proceeds past the position 2000 such that the first cam catch 2102 proceeds past the outer follower point 2304, the cam 1104 and thus the kickstand 302 will snap into the position 2300. For example, consider that a user releases the kickstand 302 when the first cam catch is between the outer follower point 2304 and the second follower catch 2306. In such a case, the sloped profile of the outer follower surface 1604 is such that pressure from outer cam follower 1604 (provided by the hinge spring 1110) drives the cam 1104 and thus the kickstand 302 into the position 2300 independent of an externally applied (e.g., user-applied) force.
According to various implementations, engagement of the first cam catch 2102 with the second follower catch 2306 enables the kickstand 302 to persist in the position 2300. For instance, spring pressure from the hinge spring 1110 holds the second follower catch 2306 against the first cam catch 2101 and thus prevents the cam 1104 and thus the kickstand 302 from disengaging from the position 2300 unless sufficient external force is applied. Thus, absent force directly and/or indirectly applied to the kickstand 302, the first cam catch 2102 will not disengage from the second follower catch 2306.
For example, the hinge 1100 is constructed such that unless a specified threshold force is applied to the kickstand 302, the hinge 1100 will not disengage from the position 2300. In at least some implementations, exceeding a threshold closing force against the kickstand 302 causes the kickstand 302 to transition back to the position 2000, and exceeding a threshold opening force against the kickstand 302 opens the kickstand 302 further past the position 2300.
Notice that in the position 2300, a second cam catch 2308 engages with a cam stop 2310 of the support plate 1108. As further detailed below, engagement of the second cam catch 2308 with the cam stop 2310 enables movement of the support plate 1108 to support further open positions for the kickstand 302.
The section view 2400 illustrates that when the kickstand 302 is in the position 2300, the inner cam surface 1400 is not in contact with the inner follower surface 1602. As mentioned above, contact between the cam 1104 and the cam follower 1106 in open positions after the open position 2000 occurs between the outer cam surface 1402 and the outer follower surfaces 1604 (illustrated in other Figures), and not between the inner cam surface 1400 and the inner follower surface 1602.
According to various implementations, movement of the kickstand 302 from the position 2300 to the position 2600 is initially resisted by pressure from the second follower catch 2306 against the first cam catch 2102. However, when movement of the first cam catch 2102 proceeds past an outer follower point 2604, pressure from the outer follower surface 1604 against the first cam catch 2102 drives the cam 1104 to the position 2600. In the position 2600, the first cam catch 2102 engages with the outer follower surface 1604.
For instance, if a user begins opening the kickstand 302 further past the position 2300 but releases the kickstand 302 before the first cam catch 2102 proceeds past the outer follower point 2604, the cam 1104 and thus the kickstand 302 will snap back into the position 2300. However, when movement of the kickstand 302 proceeds past the position 2300 such that the first cam catch 2102 proceeds past the outer follower point 2604, the cam 1104 and thus the kickstand 302 will snap into the position 2600. For example, consider that a user releases the kickstand 302 when the first cam catch 2102 is past outer follower point 2604. In such a case, the sloped profile of the outer follower surface 1604 is such that pressure from outer follower surface 1604 (provided by the hinge spring 1110) against the first cam catch 2102 drives the cam 1104 and thus the kickstand 302 into the position 2600 independent of an externally applied (e.g., user-applied) force.
For example, the hinge 1100 is constructed such that unless a specified threshold force is applied to the kickstand 302, the hinge 1100 will not disengage from the position 2600.
Further illustrated is that in moving from the position 2300 to the position 2600, engagement of the second cam catch 2308 with the cam stop 2310 causes the support plate 1108 to rotate with the cam 1104. Generally, movement of the support plates 1108 enables the hinge 1100 to provide stability to the kickstand 302 when open to various open positions.
As illustrated here, in the position 2600 the support plate 1108 partially protrudes from the hinge frame 1102. Movement of the support plate 1108 to the position 2600, for instance, is based on the interface between the plate guide 1204 of the hinge frame 1102 and the support channel 1306 of the support plate 1108. Further, a plate catch 2702 of the support plate 1108 engages with a follower contact 2704 of the cam follower 1106. According to various implementations, engagement of the plate catch 2702 with the follower contact 2704 prevents the support plate 1108 from rotating toward a further open position unless sufficient force is applied to the kickstand 302.
For instance, engagement of the plate catch 2702 with the follower contact 2704 enables the kickstand 302 to persist in the position 2600. Spring pressure from the hinge spring 1110, for example, holds outer follower surface 1604 against the first cam catch 2102 and thus prevents the cam 1104 and thus the kickstand 302 from disengaging from the position 2600 unless sufficient external force is applied. Thus, absent force directly and/or indirectly applied to the kickstand 302, the plate catch 2702 will not disengage from the follower contact 2704. For example, the hinge 1100 is constructed such that unless a specified threshold force is applied to the kickstand 302, the hinge 1100 will not disengage from the position 2600.
The position 2600, for instance, is considered a maximum open position for the kickstand 302 under normal operating conditions. A further illustrated below, movement of the hinge 1100 past the position 2600 is possible but is considered to be an emergency escape option that prevents damage to the kickstand 302 when excessive force is applied to the kickstand.
For example, consider that the computing device 102 is resting on a table or other surface with the kickstand in the position 2600. A user may accidentally place an object such as a book on the computing device 102, which exerts sufficient force on the kickstand 302 such that the kickstand 302 disengages from the position 2600 and rotates to the position 2900. As further detailed below, the force required to cause the kickstand 302 to rotate from the position 2600 to the position 2900 is significantly greater than the force required to transition between other open positions discussed above.
Further illustrated in
When the hinge 1100 is in the position 2900, the support plate 1108 compresses the cam follower 1108. For instance, a plate point 2906 of the support plate 1108 engages with a follower point 2908 of the cam follower 1106 and applies pressure to the cam follower 1106. According to various implementations, compressing the cam follower 1106 prevents the cam follower 1106 from engaging with the cam 1104 until the kickstand 302 is reset to a normal operating position.
The side view 3000 further illustrates engagement of the second cam catch 2308 with the cam stop 2310, which as discussed above, pulls the support plates 1108 out of the hinge frame 1102 to various open positions in response to user manipulation of the kickstand 302.
In at least some implementations, the contact surface of the cam stop 2310 that engages with the second cam catch 2308 is angled inward toward the second cam catch 2308, e.g., is not normal to the surface of the support plate 1108. Further, the opposing contact surface of the second cam catch 2308 is angled to provide a flat contact face between the cam stop 2310 and the second cam catch 2308. According to various implementations, this inward angling of the cam stop 2310 causes the second cam catch 2308 to pull the support plate 1108 inward and thus provide for stability of the interconnected components of the hinge 1100.
Having discussed some example kickstand and hinge positions and components, consider now a discussion of an example responsiveness profile associated with movement between the different positions.
Hinge Response Profile
Considering the different positions of the hinge 1100 and the kickstand 302 discussed above, the response profile experienced during movement of the kickstand 302 between the different positions is influenced by various factors. For instance, pressure from the hinge spring 1110 against the cam follower 1106 and thus the cam 1104 provides pressure against the various components. Depending on which position the components are in, the pressure either resists or encourages movement of the components of the hinge 1100.
Further, interaction between the different surfaces of the cam 1104 and the cam follower 1106 contributes to a responsiveness profile of the hinge 1100 and the kickstand 302. For instance, when the kickstand 302 moves from the closed position 1800 to the first open position 2000, responsiveness of the hinge 1100 is determined by contact between the inner cam surface 1400 and the inner follower surface 1602. When the kickstand moves past the first open position 2000 to the positions 2300, 2600, responsiveness of the hinge 1100 is determined by contact between the outer cam surfaces 1402a, 1402b and the outer follower surfaces 1604b, 1604a, respectively. Thus, a transition between guiding surfaces occurs at the first open position 2000.
According to various implementations, opening of the hinge 1100 after the third open position 2600 is based on interaction between the support plates 1108 and the cam follower 1106. For instance, torque required to move the hinge 1100 to the position 2900 (e.g., the emergency escape position) is based on interaction between the support plates 1108 and the cam follower 1106.
In at least some embodiments, responsiveness of the hinge 1100 can be characterized via a torque profile that indicates various forces that occur during movement of the kickstand 302 between various positions. For instance, interaction between the different cam surfaces and the different cam follower surfaces provides a detent mechanism that results in a tactile response profile for movement of the kickstand 302 between different preset positions. Consider, for example, the following example torque profiles.
According to one or more implementations, the opening torque curve 3402 represents torque transferred from the kickstand 302 to the cam 1104 when the kickstand is opened (e.g., via user manipulation) from a closed position to various open positions. The closing torque curve 3404 represents torque transferred from the kickstand 302 to the cam 1104 when the kickstand is moved (e.g., via user manipulation) from various open positions towards a closed position.
As further detailed below, the different torque curves are associated with certain “action points” or “action regions” that demonstrate the overall responsiveness profile of the hinge mechanisms discussed herein. The opening torque curve 3402, for instance, includes a first opening peak 3410, a first opening threshold 3412, a second opening peak 3414, a second opening threshold 3416, a third opening peak 3418, and a third opening threshold 3420. The closing torque curve 3404 includes, for example, a first closing peak 3422, a first closing threshold 3424, a second closing peak 3426, a second closing threshold 3428, a third closing peak 3430, and a third closing threshold 3432. Example attributes of these different points/regions are now discussed.
As an example implementation, consider that the kickstand 302 is in a closed position, e.g., 0 degrees on the torque graph 3400. A user manipulates the kickstand 302 from the closed position towards an open position. Following the opening torque curve 3402, torque against opening of the kickstand 302 gradually increases until the opening torque curve 3402 reaches the first opening peak 3410 at an open position of about 23 degrees. After the first opening peak 3410, torque values rapidly decrease until the opening torque curve 3402 intersects the angle axis 3406 at the first opening threshold 3412. In this particular example, the first opening threshold 3412 represents an open position of approximately 27 degrees.
According to one or more embodiments, if the kickstand 302 is released prior to reaching the third closing threshold 3432 (e.g., at less than 23 degrees open), the kickstand will snap back to closed, e.g., 0 degrees. Further, if the kickstand 302 is released after the first opening threshold 3412, the kickstand 302 will snap to a first preset open position, e.g., at 48 degrees. Thus, the first opening threshold 3412 represents a threshold open position for the kickstand 302 that when exceeded, allows the kickstand 302 to snap into a first preset open position. The first preset open position, for instance, corresponds to the position 2000 discussed above.
If the third closing threshold 3432 is not exceeded and the kickstand 302 is released, the kickstand will snap back into a closed position. For instance, if a user releases the kickstand at an open angle less than the third closing threshold 3432, torque active on the cam 1104 is characterized by the closing torque curve 3404.
Consider now that a user further manipulates the kickstand from the first open position (e.g., at 48 degrees) towards a further open position. Continuing from 48 degrees on the opening torque curve 2202, it can be seen that torque values rapidly increase to the second opening peak 3414. In at least some embodiments, this increase in torque represents a threshold torque required to move the kickstand from a first preset open position (e.g., the position 2000) to a second preset open position, e.g., the position 2300. For instance, the second opening peak 3414 represents the torque required to disengage the first cam catch 2102 from the first follower catch 2104, as illustrated above with reference to
If a user manipulates the kickstand 302 past the second opening peak 3414, it can be seen that the torque values of the opening torque curve 3402 rapidly decrease until the opening torque curve 3402 intersects the angle axis 3406 at the second opening threshold 3416. In this particular example, the second opening threshold 3416 represents an open position of approximately 65 degrees. According to one or more embodiments, if the kickstand 302 is released prior to reaching the second closing threshold 3428 (e.g., between the first preset open position and the second closing threshold 3428), the kickstand will snap back to the first preset open position. If the kickstand 302 is released after the second opening threshold 3416, the kickstand 302 will snap to a second preset open position, e.g., at 84 degrees. Thus, the second opening threshold 3416 represents a threshold open position that when exceeded, allows the kickstand 302 to snap into the second preset open position. In at least some embodiments, the second preset open position represents the position 2300 discussed above.
Consider now that a user further manipulates the kickstand from the second open position (e.g., at 84 degrees) towards a further open position. Continuing from 84 degrees on the opening torque curve 3402, it can be seen that torque values rapidly increase to a third opening peak 3418. In at least some embodiments, this increase in torque represents a threshold torque required to move the kickstand from a second preset open position (e.g., the position 2300) to a third preset open position, e.g., the position 2600. For instance, the third opening peak 3418 represents the torque required to disengage the first cam catch 2102 from the second follower catch 2306, as illustrated above with reference to
If a user manipulates the kickstand 302 past the third opening peak 3418, it can be seen that the torque values of the opening torque curve 3402 rapidly decrease until the opening torque curve 3402 intersects the angle axis 3406 at the third opening threshold 3420. In this particular example, the third opening threshold 3420 represents an open position of approximately 100 degrees. According to one or more implementations, if the kickstand 302 is released prior to reaching the first closing threshold 3424 (e.g., between the second preset open position and the first closing threshold 3424), the kickstand will snap back into the second preset open position. If the kickstand 302 is released after the third opening threshold 3420, the kickstand 302 will snap to a third preset open position, e.g., at 118 degrees. Thus, the third opening threshold 3420 represents a threshold open position that when exceeded, allows the kickstand 302 to snap into the third preset open position. In at least some embodiments, the third preset open position represents the position 2600 discussed above.
Continuing past the third preset open position at 118 degrees, it can be seen that the torque values rapidly increase past the previous opening torque values. In at least some embodiments, this indicates that the kickstand 302 is not intended to be opened past the third preset open position (e.g., 118 degrees) under normal operating scenarios. For instance, opening the kickstand past the third preset open position is based on an emergency release scenario, such as discussed above with reference to
When closing the kickstand 302 from the open position 2600 and/or other open position, torque acting on the cam 1104 is characterized by the closing torque curve 3404. Generally, the interpretation of the closing torque curve 3404 is opposite that of the opening torque curve 3402 since the direction of motion (e.g., closing vs. opening) is reversed. In at least some embodiments, for example, negative torque values on the closing torque curve 3404 represent closing torque applied by the user, and positive torque values on the closing torque curve 3404 represent the tendency of the kickstand to snap into a position (e.g., an open position or closed) absent resistance and/or force applied from a user.
For instance, consider that a user manipulates the kickstand 302 from the third preset open position of 118 degrees towards a closed position. Traversing the closing torque curve 3404 from the third preset open position, it can be seen that the torque forces that occur when closing the kickstand 302 are less than those that occur when opening the kickstand 302. This difference in torque profiles between opening toque and closing torque is caused at least in part by the differing profiles of the different surfaces of the cam 1104 and the cam follower 1106.
As referenced above, the closing torque curve 3404 includes the first closing peak 3422, which represents a threshold torque force required to move the kickstand 302 from the third preset open position to the second open position. When the kickstand is closed past the first closing peak 3422, the closing torque resistance decreases until the closing torque curve 3404 intersects the angle axis 3406 at the first closing threshold 3424. In this particular example, the first closing threshold 3424 represents an open angle of approximately 95 degrees. According to one or more implementations, if a user releases the kickstand 302 between the third preset open position and prior to reaching the third opening threshold 3420, the kickstand 302 will snap back into the third preset open position. However, if the user releases the kickstand 302 after reaching the first closing threshold 3424 (e.g., at or less than about 95 degrees), the kickstand 302 will snap into the second preset open position.
The second closing peak 3426 represents a threshold torque required to move the kickstand 302 from the second present open position to the first preset open position, e.g., to transition from the position 2300 to the position 2000. When the kickstand is closed past the second closing peak 3426, the closing torque resistance decreases until the closing torque curve 3404 intersects the angle axis 3406 at the second closing threshold 3428. In this particular example, the second closing threshold 3428 represents an open angle of approximately 61 degrees.
In at least some embodiments, if a user releases the kickstand 302 between the second preset open position and prior to reaching the second opening threshold 3416, the kickstand 302 will snap back into the second preset open position. However, if the user releases the kickstand 302 after reaching or exceeding the second closing threshold 3428 (e.g., at or less than about 61 degrees), the kickstand 302 will snap into the first preset open position.
The third closing peak 3430 represents a threshold torque required to move the kickstand 302 from the first present open position to a closed position, e.g., to transition from the position 2000 to the position 1800. When the kickstand is closed past the second closing peak 3430, the closing torque resistance rapidly decreases until the closing torque curve 3404 intersects the angle axis 3406 at the third closing threshold 3432. In this particular example, the third closing threshold 3432 represents an open angle of approximately 24 degrees.
In at least some embodiments, if a user releases the kickstand 302 between the second preset open position and prior to reaching the first opening threshold 3412, the kickstand 302 will snap back into the first preset open position. However, if the user releases the kickstand 302 after reaching or exceeding the third closing threshold 3432 (e.g., at or less than about 24 degrees), the kickstand 302 will snap into the closed position, e.g., 0 degrees.
As illustrated in
As further illustrated by the torque graph 3400, the hinge mechanism discussed herein is designed to minimize the torque required to maintain the “snappiness” response. In at least some embodiments, this minimum torque is approximately 20 N-mm. Further, the opening torque curve 3402 and the closing torque curve 3404 are trapezoidal in shape, for example, as opposed to sinusoidal curves. This illustrates the snappy transition between the different preset hinge positions.
Thus, according to various implementations, the torque curves characterize torque values that apply during movement of the kickstand 302. For instance, the opening torque curve 3402 represents the torque that is applied when opening the kickstand 302 from the closed position 1800 through the various different open positions. Further, the closing torque curve 3404 represents the torque that is applied when closing the kickstand 302 from various open positions to the closed position 1800.
It should be noted that in the closing torque curve 3404, a negative torque represents the user actively applying torque to close the kickstand, e.g., external force applied to the kickstand 302. A positive torque on the closing torque curve 3404 represents the kickstand tending to close itself due to force generated internally to the hinge 1100 (e.g., by the hinge spring 1110) to cause the hinge to “snap” between various positions.
The torque graph 3500 includes an emergency release peak 3510, which corresponds to an amount of torque required to disengage the kickstand 302 from the third preset open position to a further open position, e.g., to open the kickstand 302 to the position 2900. As discussed above, in at least some implementations the kickstand 302 is not intended to be opened past the third preset open position under normally operating conditions. Thus, the amount of torque required to further open past the third preset open position is considerably greater than the torque values discussed with regard to the previous open positions.
In this particular example, the emergency release peak 3510 indicates that approximately 1700 N-mm are required to open the kickstand 302 past the third preset open position. For instance, the emergency release peak 3510 specifies an amount of opening torque required on the kickstand 302 to disengage the plate catch 2702 form the follower catch 2704, discussed above with reference to
Notice in the torque graph 3500 that the closing torque curve 3504 differs from the closing torque curve 3404 discussed with reference to

Accordingly, embodiments discussed herein provide a stable hinge mechanism that enables an attached component (e.g., a kickstand) to be adjusted between multiple preset positions. It is to be appreciated that the example device orientations, kickstand positions, hinge positions, hinge preset positions, torque values, and so forth discussed above are presented for purposes of example only.

Further, example hinges can be attached at any suitable position and/or portion of a kickstand and/or computing device in accordance with the claimed embodiments.

Various techniques may be described herein in the general context of software, hardware elements, or program modules. Generally, such modules include routines, programs, objects, elements, components, data structures, and so forth that perform particular tasks or implement particular abstract data types. The terms “module,” “functionality,” and “component” as used herein generally represent software, firmware, hardware, or a combination thereof.

“Computer-readable storage media” may refer to media and/or devices that enable persistent storage of information in contrast to mere signal transmission, carrier waves, or signals per se. Thus, computer-readable storage media refers to non-signal bearing media. The computer-readable storage media includes hardware such as volatile and non-volatile, removable and non-removable media and/or storage devices implemented in a method or technology suitable for storage of information such as computer readable instructions, data structures, program modules, logic elements/circuits, or other data.

“Computer-readable signal media” may refer to a signal-bearing medium that is configured to transmit instructions to the hardware of the computing device 3602, such as via a network. Signal media typically may embody computer readable instructions, data structures, program modules, or other data in a modulated data signal, such as carrier waves, data signals, or other transport mechanism. Signal media also include any information delivery media. The term “modulated data signal” means a signal that has one or more of its characteristics set or changed in such a manner as to encode information in the signal. By way of example, and not limitation, communication media include wired media such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared, and other wireless media.
As previously described, hardware elements 3610 and computer-readable media 3606 are representative of modules, programmable device logic and/or fixed device logic implemented in a hardware form that may be employed in some embodiments to implement at least some aspects of the techniques described herein, such as to perform one or more instructions. Hardware may include components of an integrated circuit or on-chip system, an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a complex programmable logic device (CPLD), and other implementations in silicon or other hardware.

Combinations of the foregoing may also be employed to implement various techniques described herein. Accordingly, software, hardware, or executable modules may be implemented as one or more instructions and/or logic embodied on some form of computer-readable storage media and/or by one or more hardware elements 3610. The computing device 3602 may be configured to implement particular instructions and/or functions corresponding to the software and/or hardware modules. Accordingly, implementation of a module that is executable by the computing device 3602 as software may be achieved at least partially in hardware, e.g., through use of computer-readable storage media and/or hardware elements 3610 of the processing system 3604. The instructions and/or functions may be executable/operable by one or more articles of manufacture (for example, one or more computing devices 3602 and/or processing systems 3604) to implement techniques, modules, and examples described herein.
Implementations discussed herein include:

Implementations further include a mobile device as recited above, wherein the emergency escape position includes a 180 degree rotation of the support component from a closed position on the rear portion of the mobile device.
Implementations further include a mobile device as recited above, wherein the hinge mechanism comprises: a hinge frame; at least one support plate slidably engaged with the hinge frame; a cam slidably engaged with the at least one support plate, the cam being attached to the support component to enable attachment of the support component to the hinge mechanism; and a cam follower pivotably mounted within the hinge frame and positioned such that in at least some of the multiple preset open positions, the cam follower interfaces with the cam such that variable torque forces occur when transitioning between the at least some of the multiple preset open positions.
Implementations further include a mobile device as recited above, wherein in at least one of the multiple preset open positions, a first surface of the cam follower engages with a first surface of the cam, and wherein in at least one other of the multiple preset open positions, a second surface of the cam follower engages with a second surface of the cam.
Implementations further include a mobile device as recited above, wherein the hinge mechanism is configured such that during movement hinge mechanism from the at least one of the multiple preset open positions to the at least one other of the multiple preset open positions, contact between the cam and the cam follower transitions between contact between the first surface of the cam and the first surface of the cam follower, to contact between the second surface of the cam and the second surface of the cam follower.
Implementations further include a mobile device as recited above, wherein the hinge mechanism is configured such that in an event that a user manipulates the support component and releases the support component with the hinge mechanism not positioned in one of the multiple preset open positions, the hinge mechanism will snap into one of the multiple preset open positions independent of user interaction with the support component.
Implementations further include a hinge mechanism comprising: a hinge frame with at least one support plate slidably mounted on a plate guide on an interior surface of the hinge frame; a cam slidably mounted on a cam guide on an interior surface of the at least one support plate, the cam including an inner cam surface, at least one outer cam surface, and a mounting portion for mounting a moveable component to the cam; a cam follower pivotably mounted within the hinge frame and including an inner follower surface positioned to be engageable with the inner cam surface, and at least one outer follower surface positioned to be engageable with the at least one outer cam surface; and a hinge spring mounted within the hinge frame and that applies force to the cam follower such that the cam follower is held in contact with the cam in at least some positions of the hinge mechanism, the hinge mechanism being configured such that during movement of the cam, contact between the cam and the cam follower transitions between contact between the inner cam surface and the inner follower surface, to contact between the at least one outer cam surface and the at least one outer follower surface, thus enabling the hinge mechanism to snap into different preset open positions.
Implementations further include a hinge mechanism as described above, wherein the moveable component comprises a support component for an apparatus, and wherein the hinge mechanism enables the support component to be positioned at multiple positions relative to the apparatus.
Implementations further include a hinge mechanism as described above, wherein the inner follower surface and the at least one outer follower surface have different surface profiles.
Implementations further include a hinge mechanism as described above, wherein the at least one support plate includes a plate channel that is slidably engaged with the plate guide on the interior surface of the hinge frame.
Implementations further include a hinge mechanism as described above, wherein the hinge mechanism is configured with an emergency escape position that occurs in response to movement of the hinge mechanism beyond the different preset open positions.
Implementations further include a hinge mechanism as described above, wherein a torque applied to the cam to cause the hinge mechanism to transition to the emergency escape position is greater than a torque applied to the cam to transition the hinge mechanism between the different preset open positions.
Implementations further include an apparatus comprising: a chassis; and at least one hinge mechanism that attaches a component to the chassis and that is positionable in multiple preset open positions, the hinge mechanism including: a hinge frame with at least one support plate, a cam, and a cam follower mounted therein, a response profile of the hinge mechanism for at least some of the multiple preset open positions being based on interaction between the cam and the cam follower, and interaction between the at least one support plate and the hinge frame enabling the hinge mechanism to be positioned beyond the at least some of the multiple preset open positions independent of interaction between the cam and the cam follower.
Implementations further include an apparatus as described above, wherein the hinge mechanism is configured such that the component is positionable via the hinge mechanism at the multiple preset open positions, and such that if the component is released between a first preset open position and a second open preset position, the component snaps into one of the first present open position or the second preset open position independent of user interaction with the component.
Implementations further include an apparatus as described above, wherein the hinge mechanism is configured such that the at least one support plate engages with the hinge frame between the cam and the hinge frame, and the cam engages with the at least one support plate.
Implementations further include an apparatus as described above, wherein the hinge mechanism is configured such that positioning the hinge mechanism beyond the at least some of the multiple preset open positions causes the cam to disengage from the cam follower.
Implementations further include an apparatus as described above, wherein the hinge mechanism is configured such that positioning the hinge mechanism beyond the at least some of the multiple preset open positions causes the at least one support plate to compress the cam follower such that the cam follower does not engage the cam until the cam is reset to at least one of the multiple preset open positions.
Implementations further include an apparatus as described above, wherein a torque applied to the cam to cause the hinge mechanism to transition beyond the at least some of the multiple preset open positions is greater than a torque applied to the cam to transition the hinge mechanism between the at least some of the multiple preset open positions.
