The present invention relates to a docking station for an electronic device. More particularly, the present invention relates to a docking station having a connector that is more durable.
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. 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 with a connector that is more 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. In one example, if the portable electronic device is pushed forward, the connector can rotate, thereby reducing the likelihood of breakage from such a push.
Additionally, the rotatable connector may be biased with a biasing mechanism to keep a portable electronic device in an upright position such that the electronic device is supported by a rear reference surface of the docking station, thereby preventing undue strain on the rotatable connector in the upright position. The biasing mechanism can act by opposing movement forward to keep the electronic device in a position to be supported by the rear reference surface. The rotatable connector may be partly below and partly above an outer shell of a base of the docking station, and pivot at the outer shell of the base, thereby reducing possible damage to parts (e.g. a rotation mechanism) below the outer shell. The rotatable connector may also retract when rotated, which can remove the connector from the device, and thus can stop the force from acting on the connector.
According to one embodiment, a docking station can include a base, a rear reference surface, and a rotatable connector that is configured to receive and electrically couple to a receptacle connector of a portable electronic device. The rotatable connector can be coupled to the base and biased toward an 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.
According to another embodiment, a docking station can include a base with an outer shell having an opening and a rotatable connector that is configured to receive and electrically couple to a receptacle connector of a portable electronic device. The rotatable connector can be coupled to the base and protrudes through the opening in the outer shell of the base. The rotatable connector can have a first section below the outer shell and a second section above the outer shell. During at least a portion of a rotation, the rotatable connector pivots about a point of contact between a surface of the rotatable connector and the outer shell.
According to yet another embodiment, a docking station can include a base with an outer shell having an opening and a rotatable connector that is configured to receive and electrically couple to a receptacle connector of a portable electronic device. The rotatable connector protrudes through the opening in the outer shell such that the rotatable connector has a first section below the outer shell and a second section above the outer shell. The docking station also includes at least one guide post coupled with the rotatable connector and at least one guiding surface that is in contact with the at least one guide post. The at least one guiding surface guides a position of the rotatable connector during rotation of the rotatable connector.
According to yet another embodiment, a docking station includes a base, rotatable connector (configured to receive and electrically couple to a receptacle connector of a portable electronic device), and a retraction mechanism. The base has a bottom surface and a top outer shell that has an opening. The rotatable connector protrudes through an opening in the top outer shell such that the rotatable connector has a first section below the top outer shell and a second section above the top outer shell. The retraction mechanism causes the second section of the rotatable connector that is above the outer shell to decrease as the rotatable connector rotates from a position perpendicular to the bottom surface towards a front of the docking station.

Embodiments of the present invention provide a docking station (dock) that provides a connector that is more durable. Such durability 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 embodiment, for example, the connector may be configured to rotate relative to the dock base in order to better distribute the forces when an off axis force is applied, i.e., it moves with the force rather than completely resisting the force by not moving. Other features, which help to provide a more durable connector, include a rear reference surface of the docking station that supports the portable electronic device when the connector is in an upright position, a pivot mechanism that protects certain moving parts by keeping them within the base of the dock, and a retraction mechanism that can help discharge the connector from the portable electronic device prior to the connector rotating all the way forward also help to provide a more durable connector. The exact 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.
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 non-portable devices.
FIG. 1 is a perspective view of a connector assembly 100 according to embodiments of the present invention. The connector assembly 100 includes a connector 120 that protrudes away from a surface 140. The connector 120 generally defines a mating axis 130 along which a corresponding mating connector can be attached and removed. The corresponding mating connector may for example be a connector carried by an electronic device. The connectors can slide on/off along an axis 130 in order to couple and decouple the electrical contacts associated with the connectors.
In one embodiment, connector 120 may be exposed and substantially free from external walls and surfaces (e.g. no or limited walls that surround or are adjacent to the connector). As such, connector 120 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. For example, in one embodiment, connector 120 is not disposed within a recess or cavity and instead extends outward from a surface such that its sides are exposed.
Because connector 120 can be exposed and substantially free from reference surfaces, undesirable off-axis forces may be exerted on connector 120 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 120. 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. A configuration of connector 120 may lead to more susceptible areas of undesirable forces. For example, in cases where connector 120 is wide in x dimension and thin in y dimension (as shown), the connector may be more susceptible to rotations about the x axis.
In order to minimize these types of forces on connector 120 while using limited or no reference surfaces, in one embodiment, connector assembly 100 further includes a force distribution joint 160 that is coupled with connector 120. Force distribution joint 160 may be configured to allow an absorbing of these forces (e.g. by allowing connector 120 to move), especially off-axis forces caused by rotating the electronic device off of connector 120. For example, tilting the electronic device can impart a bending moment on connector 120, which can then tilt in conjunction with force distribution joint 160.
Force distribution joint 160 may be widely varied. In some cases, it may be configured to absorb undesirable forces in specific directions (e.g., rotations about x); while in other cases, it may be configured to absorb undesirable forces in multiple directions (translations in x,y,z and/or rotations about x,y,z). Force distribution joint 160 may for example allow connector 120 to move such that the forces are no longer imparted on a fixed joint, i.e., the forces are distributed.
Force distribution joint 160 can include one or more flexures, rotational mechanisms, translational mechanisms, etc. In one implementation, force distribution joint 160 may be formed from a compliant or flexible material that yields when undesirable forces are imparted on the connector. For example, foams, springs, and the like may be used. Alternatively or additionally, force distribution joint 160 may be formed from one or more motion mechanisms that yield when undesirable forces are imparted on the connector. For example, pivots, slides and the like may be used. In various embodiments, a bottom section of connector 120 may be embedded in a compliant or flexible material to form force distribution joint 160 or a bottom surface of connector 120 may be attached to the compliant or flexible material to form force distribution joint 160.
In some embodiments, limited reference surfaces may be used in addition to force distribution joint 160. For example, a single reference surface may be used to help guide and support an electronic device, such as a flat portable electronic device (e.g. a phone). The single reference surface may for example help support the back surface of the electronic device. The reference surface may even help position the electronic device in a desired position (e.g., upright or substantially upright viewing position). Unfortunately, the reference surface may instigate unwanted forces. For example, a user may pull the device away from the reference surface during a removal event (thereby causing the connector to rotate). In this particular case, force distribution joint 160 may be especially geared to absorb these rotational forces. In one example, force distribution 160 joint may allow connector 120 to rotate in the direction away from the reference surface.
It should be appreciated that force distribution joint 160 can be tuned or dampened to provide a desired counter force to the undesirable force. For example, springs may be used to help bias the connector in a direction against the direction of the undesirable forces (e.g., off-axis forces). It should also be appreciated that force distribution joint 160 may be hidden from view as for example within or underneath the surface 140 (as shown by dotted lines).
In one embodiment, surface 140 may be a top surface of a docking station to which the electronic device is designed to be coupled. Such a docking station can provide a platform for quickly and easily coupling a portable electronic device to another system or device as for example a computer, a power source, or peripheral devices such as a monitor, a keyboard, speakers, etc. The docking station can also hold the electronic device in a position suitable for viewing a display of the electronic device.
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 120 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 120, as connector 120 moves. For example, a printed circuit board may slide along rails. Certain embodiments are described in more detail below.
Connector 120 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 120 may be wired directly to the components of the host device or system. In some cases, connector 120 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 120 can correspond to USB, Firewire, or other standardized connector formats. In one example, connector 120 is a 30-pin connector compatible with the Apple iPod� and iPhone™ devices. In an embodiment, the 30-pin connector has a long 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 120, 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.
Moveable connector 120 may move between a closed position and one or more open positions for engaging a corresponding connector of the electronic device. In one embodiment, the corresponding connector is incapable of engaging connector 120 in the closed position. In some cases, the connector movement may be a combination of different movements such as for example translation and rotation. For example, connector 120 may rotate forward from the upright position while sliding to be placed in a closed position.
In the closed position, connector 120 may be at least partially within the confines of the docking station and in some cases entirely within the confines of the docking station. Connector 120 may be housed in a recess or void or cavity in the docking station when connector 120 is in the closed position. In some cases, the arrangement may provide a substantially flush surface on the top surface 140 when connector 120 is in the closed position. In addition, in some arrangements, connector 120 may even be hidden from view.
In the upright position, on the other hand, connector 120 may extend outward from surface 140. This may be beneficial in that connector 120 may need to be completely or partly exposed outside of the body in order to connect with certain devices. As used herein, the term “upright position” includes any position of connector 120 in which a user can use a device when connected to connector 120. Although the term upright position may be a single position, in some cases, it may refer to a plurality of upright positions. For example, connector 120 may have multiple upright positions that place the connector at different orientations/locations/distance away from the body. These positions may be at a number of designated points.
A docking station according to embodiments of the present invention may also include a biasing mechanism, which be part of or separate from force distribution joint 160. The biasing mechanism may be configured to keep connector 120 in an upright position (where the device can be supported and available for viewing). The biasing mechanism may, for example, include a spring (any object with a spring constant) that continuously biases connector 120 toward an upright position. A locking mechanism can keep connector 120 in a closed position. The lock may, for example, be released via a button positioned on the docking station, which when activated allows the biasing mechanism to move connector 120 to an upright position. Once released, connector 120 may be repositioned within the body by simply forcing connector 120 back into surface 140 against the spring force until the lock reengages connector 120. In one embodiment, detents may be used to hold, or at least stabilize, connector 120 in various upright positions. In embodiments where connector 120 rotates, the biasing mechanism can also prevent connector 120 from rotating past an end point (e.g. full rotation forward) where connector 120 does not rotate any further.
Regarding embodiments where a movement of connector 120 is rotation, connector 120 moves using a rotation mechanism that links the connector and a body of the dock together. In one example, force distribution joint 160 can be the rotation mechanism. In one embodiment, connector 120 can pivot at surface 140 with other parts of the rotation mechanism protected underneath surface 140. In another embodiment, connector 120 and the rotation mechanism may be formed into a single integral unit. The amount of rotation that is provided may vary and can depend on the desired orientation of the electronic device when it is docked, and/or other features of the dock. For example, the amount of rotation can permit the electronic device to be placed in a substantially upright position (exposing its display and/or user interface). The rotation mechanism can include gears, cams, followers, and the like.
FIGS. 2A-2E show a cross-sectional side view of a docking station 200 according to an embodiment of the present invention. As mentioned above, docking stations such as docking station 200 can provide a platform for quickly and easily coupling an electronic device 212 to another system or device as for example a computer, a power source, or peripheral devices such as a monitor, a keyboard, speakers, etc. Docking station 200 can also hold electronic device 212 in a position suitable for viewing a display 213 of the electronic device.
Docking station 200 may include a base 230, which may contain various electronics, ballast, and the like. Base 230 can serve to keep docking station 200 balanced and supported on a surface such as a table, as well as keep electronic device 212 balanced and supported when mounted thereto. Docking station 200 may also provide one or more reference surfaces for helping support the electronic device in an upright position. In the illustrated embodiment, docking station 200 can include a rear reference surface 240 that protrudes upwardly from base 230 and that helps define the desired position of electronic device 212 when electronic device 212 is mounted to docking station 200. For example, the back surface of electronic device 212 contacts with rear reference surface 240. In some cases, additional reference surfaces may be provided. For example, one or more side support members may help mate the connector of electronic device 212 with connector 214.
The angle of rear reference surface 240 may generally define the angle of the electronic device when mounted. The angle may for example be about 0-30 degrees and more particularly between about 10 and 15 degrees. Rear reference surface 240 may be widely varied. For example, it may consist of one or more rear support members that are coupled to base 230. Base 230 and the rear support members may be formed as a single integral unit or they may be separated parts that are attached together. In most cases, the base and rear support members are fixed to one another. However, it is contemplated that the position of the rear support members may be adjustable relative to the base (thereby enabling multiple positions for viewing or even a retracted position for travelling). In some cases, the rear support members may be detachable from base 230. The length of the rear support members generally correspond to that which is required to properly support the electronic device in an upright position. In some cases, it may extend higher than electronic device 212 while in other cases it may extend below electronic device 212 (as shown). Of course, it may even have a similar length such that the top edge are about the same height. In some cases, the rear support members may be height adjustable so that different devices can be supported by docking station 200.
Docking station 200 may include at least one connector 214. Connector 214 may protrude upwardly from base 230 and may be configured to interface with a corresponding connector(s) of the electronic device when the electronic device is positioned relative to the docking station and more particularly the rear reference surface. In some embodiments, connector 214 can be partly within an interior of base 230 and protrude through an opening 215 in an exterior surface. In other embodiments, rotatable connector 214 can be completely above an exterior surface. The connector may protrude upwardly at an angle similar to the rear support members. As such, rear reference surface 240 may be used as a reference surface during placement of the electronic device relative to the connector. The connectors may for example interface along an axis 205. That is, they may be coupled/decoupled to/from each other along axis 205. Axis 205 provides the direction into which the contacts of the connector mate with one another.
In one embodiment, connector 214 may be rotatably coupled to base 230 via a rotation mechanism (not shown). Connector 214 can for example rotate between the upright position (FIG. 2B) that is substantially parallel to the rear support member and various rotated positions (FIGS. 2C and 2D) that are angled away from the upright position. The rotation mechanism can allows electronic device 212 to rotate forward from an upright position (which may be used for viewing a display) to other positions when electronic device 212 is forced forward as for example in a removal or inadvertent knock event. As a result, undue stress on the connector is reduced or prevented, which over time may lead to failure at the joint of connector 214.
The rotation mechanism may be widely varied. In some embodiments, the rotation mechanism can include a pivot such as a cylindrical or other shaped rod that can be attached to, or be part of, the bottom of connector 214 and that interfaces with pivot holes in the base (or vice versa). As examples, the rod may attach to a side of base 230 or rest on or within a cavity that holds the rod while allowing the rod to rotate. In another embodiment, the rotation is about an edge at an outer shell of base 230.
Docking station 200 may also include biasing mechanism 226, which biases connector 214 to reside in an upright position. In the embodiment shown, biasing mechanism 226 is a spring (e.g. a solid springy material such as rubber or similar synthetic materials) that pushes back with greater force when its length is made shorter. In another embodiment, biasing mechanism 226 pulls connector 214 to reside in an upright position when its length is made longer. In one aspect, at least one part (e.g., the end farther from the connector) of biasing mechanism 226 is held into place, such that at least one dimension of the biasing mechanism is reduced when the bottom of connector 214 moves to the right. Biasing mechanism 226 may use various spring materials to tune and dampen the motion of connector 214 as it rotates forward. An operation of biasing mechanism according to one embodiment is discussed further below, e.g., with relation to FIGS. 3A and 3B.
Docking station may also include connection 224 configured to electrically couple the connector with the electronics 222. Connection 224 may provide an electrical connection from contacts at the bottom end of the connector 214 to electronics 222, which may be a data and/or power connector. For example, connection 224 may be a flexible member that provides some slack to enable movement of the connector. The flexible member may for example be a ribbon cable or a flexible circuit, which is not always taught. Alternatively, swiping contacts may be used.
To elaborate, FIG. 2B shows the docking station 200 coupled with a portable electronic device 212 that is supported by back 240 when rotatable connector 214 is in an upright position according to an embodiment of the present invention. As shown, rotatable connector 214 is configured to receive a receptacle connector of portable electronic device 214. Contacts at the top end of connector 214, which are part of or are electrically coupled with the contacts at the bottom end of connector 214, may couple connection 224 to the receptacle connector, thereby providing electrical connection between receptacle and electronics 222.
As shown, rear reference surface 240 is adapted to support portable electronic device 212 when the electronic device is coupled to rotatable connector 14 in its upright position. In one embodiment, rear reference surface 240 supports portable electronic device 212 prior to rotatable connector 14 reaching its full rotation backward (clockwise as shown). In another embodiment, rear reference surface 240 supports portable electronic device 212 when it is fully rotated backward. Rear reference surface 240 can support the weight of the connected portable electronic device 212 so that this weight does not continue to put a force on connector 214, e.g., when device 212 is being viewed. In this manner, strain on connector 214 can be reduced, and connector 214 can be more durable.
Although strain on connector 214 in the backward direction can be reduced by rear reference surface 240, there may be instances where portable electronic device 212 is inadvertently pushed or moved forward. For example, when attempting to remove portable electronic device 212 from docking station 200, a user might knock portable electronic device 212 forward. Such motion could put strain on the connector 214. However, since the connector 14 can rotate forward, such a strain can be reduced or potentially eliminated when the force is first applied.
Biasing mechanism 226 can ensure that connector 214 is in the proper location such that electronic device 212 is supported by rear reference surface 240 once attached. Biasing mechanism 226 can also provide an opposing force that makes it easier to attach device 212. Additionally, when device 212 is moved forward, biasing mechanism 226 can provide a force to return device 212 against the rear reference surface 240. Otherwise, device 212 may fall forward, which could break connector 214. FIGS. 2C and 2D illustrate such a biasing force.
FIG. 2C shows docking station 200 connected to rotatable connector 214 where portable electronic device 214 is moved forward relative to the rear reference surface 240. For example, device 212 may have been pushed or pulled forward as a user's hand is grabbing for the device. As shown, device 212 no longer rests against rear reference surface 240.
As device 212 has moved forward, biasing mechanism 226 provides a force 260 that pushes the connector 14 backward (clockwise as shown). In one aspect, this force 260 may be strong enough to counteract the counterclockwise (i.e. forward) force on the connector from device 212. Note that the forward force may be of a short duration, e.g., when the device is being lifted up or just slightly nudged. If device 212 is no longer attached, then connector 214 may return to an upright position. If the device is still attached, but the forward force from device 212 is not stronger (or is no longer existing) than the backward force 260, then device 212 may return to resting against rear reference surface 240.
In the embodiment shown, the bottom of connector 214 moves as connector 214 rotates. Counterclockwise rotation of connector 214 pushes its bottom portion against biasing mechanism 226, which causes biasing mechanism 226 to push back to the left with an increasing amount of force as the length of the biasing material (e.g. a spring) decreases. In one embodiment, connector 214 pivots about one or more edges of an outer shell of base 230 during at least a portion of a rotation.
In another embodiment, pivoting of a connector occurs below an outer shell of a base of a docking station, e.g., at the bottom of the connector. In yet another embodiment, pivoting of a connector occurs above a top surface of an outer shell, e.g., when the entire connector is above a top surface of the base. In these embodiments, the connector may have a fixed axis of rotation at a rod that is mechanically coupled to the connector. For example, the rod may pass through a cylindrical hole near the bottom of the connector, or the rod may be attached to a surface of the connector. In various embodiments, the rod can be attached to sides, an inner bottom surface, or an inner top surface of the base so that the rod rotates, but does not translate. In some embodiments, a biasing mechanism can be a curved spring with a first end attached to the base (e.g. at a point forward from the connector) and a second end attached to a surface of the connector. In this manner, when the connector rotates in one direction (e.g. forward), the spring's length decreases as the surface of the connector becomes closer to the point of attachment of the first end and a biasing force backward can be provided. As another example, the biasing mechanism may be a spring that loops around and attaches to the rod that is part of a rotation mechanism. As the rod rotates, the spring deforms, thereby producing a biasing force.
In one aspect, biasing mechanism 226 can prevent device 212 from becoming vertical after a small push forward. For example, if the push has only a small magnitude and is only for a small duration, backward force 260 can prevent the device from rotating past the vertical. As long as the forward rotation is counteracted, the weight of the device and the continued restoring action of backward force 260 can return device 212 to being supported by rear reference surface 240. However, if device 212 moves past the vertical position, then force 260 may need to be increased significantly.
FIG. 2D shows docking station 200 connected to the rotatable connector 214 where portable electronic device 212 is moved past a vertical position. Device 212 is shown in a more forward position than in FIG. 2C. Correspondingly, backward force 260 has increased (as depicted with a larger arc length). In one embodiment, a decrease in the length of biasing mechanism 226 causes force 260 to become larger.
This increase in force 260 may be made to be larger than the component of the weight of the device 212. Thus, if an external force (e.g. from a user's hand) is no longer pushing on the device 212, it may be possible to return the device to an upright position, e.g., where the device 212 is supported by the rear reference surface 240.
In embodiments where connector 214 is partly within an interior of body 230 and where a bottom of connector 214 is allowed to move, connector 214 may have additional features which keep connector 214 from being pulled out of body 230.
FIG. 2E shows an aerial view of docking station 200 according to embodiments of the present invention. Connecter 214 is shown in a substantially vertical position in opening 215 of body 230. One or more restraint members 219 (such as pins, rods, protrusions, or the like) extend from sides of connector 214 past edges of opening 215. Thus, if connector 214 is pulled in upward direction, restraint members 219 prevent connector 214 from being pulled completely out of the interior of body 230. In one embodiment, the downward force on restrain members 219 may be provided by the exterior surface in which the opening 215 resides. In another embodiment, the downward force may be applied by another surface or edge that is between the restraint members and the exterior surface. Restraint members 219 may also be supported below by a surface (which may be a bottom exterior surface of body 230) such that connector 214 does not fall completely within an interior of body 230.
Other features of connector 214 can also extend beyond the edges of opening 215. For example, members may extend forward (left as drawn) or backward (right as drawn) beyond edges of opening 215. In another embodiment, connector 214 may have an angled shape such that a bottom within the interior of body 230 is larger than opening 215.
Besides protecting the connector from damage as forces are applied to connector 214 via device 212, some embodiments protect the rotation mechanism from damage. For example, if the rotation mechanism was exposed, it may be hit or particles may contaminate the rotation mechanism. Additionally, a flat or relatively uniform surface of the base may be desired for functional or aesthetic reasons. To provide these features, embodiments have the rotatable connector pivot at an outer shell of the body.
FIGS. 3A and 3B show a cross-sectional side view of a connector assembly 300 according to an embodiment of the present invention. The connector assembly 300 may generally correspond to the system shown in FIGS. 2A-2E. Connector assembly 300 shows a rotation mechanism where a connector pivots about an edge of a body of a docking station.
The connector assembly 300 may include a rotatable connector 314 that is disposed through an opening 333 in an outer shell 334 (such as the upper wall of the base of the docking station). Opening 333 has a shape that enables the rotatable connector 314 to rotate between a nominal upright position (as shown in FIG. 3A) and a tilted position (as shown in FIG. 3B). Outer shell 334 has a section 334 a to the left of connector 314 and a section 334 b to the right of connector 314. The outer shell is shown to have a thickness (t). The thickness (t) is not drawn to any particular scale, e.g., it could be larger or smaller in relation to the height of connector 314 of height of the base. The base also has a bottom 332, e.g., which can rest upon a supporting surface when the docking station is in use. This bottom surface 332 may be formed integrally with the outer shell 334 and may also have a same thickness t.
When the connector is substantially rotating from tilted position to nominal position the rotatable connector may be configured to pivot about edge 337 b of section 334 b. When the connector is substantially rotating from the nominal position to the tilted position the rotatable connector may be configured to pivot about the edge 337 a of section 334 a. In so doing, opening 333 may be sized or dimensioned to be substantially similar to the size of the connector (with minimal gap for tolerance). In this embodiment, the bottom of the connector 314 is allowed to move during its rotation.
In FIG. 3A, connector 314 is shown in an upright position. In one embodiment, a biasing mechanism 326 (which can be similar to biasing mechanism 226 of FIG. 2A) is at or near its relaxed length. In various embodiments, connector 314 may be prevented from further rotation in the backward direction (clockwise as shown), e.g., by an edge 337 b, an edge 337 c, a surface 336 a, or by another object (such as a fixed stop) below the section 334 a, or by any combination thereof.
In the position shown in FIG. 3A, connector 314 is prevented from further clockwise rotation by edge 337 b of surface 336 b and edge 337 c of the surface 336 a. FIG. 3B shows connector 314 rotated fully in the forward (counterclockwise) direction. As shown in FIG. 3B, connector 314 is now prevented from further counterclockwise rotation by edge 337 a of surface 336 a and the whole surface 336 b. In other embodiments, a bottom portion of surface 336 b can act as a stop to prevent the rotation. Having the whole surface 336 b act as a stop can provide a larger stopping force and greater durability.
In the embodiment shown, opening 333 in outer shell 334 is large enough that connector 314 is not in contact with both edges 337 a and 337 b in the fully rotated clockwise position of FIG. 3A. In one aspect, this is because connector 314 can rotate further in counterclockwise direction from the vertical (i.e. perpendicular to the bottom surface 332) than it can clockwise. Surfaces 336 a and 336 b may have different slopes to allow for such asymmetric range of motion. If connector 314 can rotate the same in both directions, then there may be none or a reduced space between edges 337 a,337 b when connector 314 is fully rotated in either direction. At other positions, connector 314 is generally not touching both sections 334 a and 334 b, and may be touching neither section.
As the bottom of connector 314 is allowed to move backward (to the right as drawn), the top of connector 314 can move to the left (e.g. as a result of the connected portable electronic device 212 moving). Also, as the bottom of connector 314 moves, biasing mechanism 326 also moves, thereby providing a force that tries to move connector 314 back into the upright position in FIG. 3A (although in some embodiments the force may not be strong enough to overcome the force imparted from the portable electronic device).
Accordingly, edges of outer shell 334 can act as pivots during various portions of the rotation of connector 314. Having edges of outer shell 334 acting as a pivot allows the sections 334 a and 334 b to be close to the connector 314. Thus, opening 333 can be quite small. Having a small opening can prevent dirt, crumbs, or other foreign objects from falling onto the internal components of the base. Additionally, in one embodiment, when connector 314 is in the nominal upright position, a seal can be formed by connector 314 touching edge 337 c and edge 337 b. Thus, even a liquid may be prevented from entering the dock through opening 333.
In one embodiment, connector 314 can be attached to an edge (e.g. one of edges 337 a or 337 b), while other embodiments do not have such an attachment. Such attachment may be formed from a hinge or other rotary mechanism and can allow for a fixed axis of rotation in some embodiments, while other embodiments do not have a fixed axis of rotation.
In one embodiment, the amount of rotation allowed can be controlled in part by selecting the angles 338 a and 338 b of the respective surfaces 336 a and 336 b. The angles of the surfaces 336 a and 336 b may be varied. In one embodiment, angle 338 a is smaller than angle 338 b. In such an embodiment, connector 314 can rotate further in the counterclockwise direction from the vertical position than in the clockwise direction. In another embodiment, the amount of rotation allowed can be controlled in part by the size of the gap between edge 337 a and edge 337 b. Also in various embodiments, the bottom of connector 314 can be supported by biasing mechanism 326, a guide surface (e.g. the bottom 332 or another surface between surfaces 334 and 332), notches on sides of the base (e.g. where a rod extending from connector 314 can attach), or other suitable supports. In one embodiment, a guide surface can be relatively flat while in other embodiments a guide surface can have features, e.g., curves or notches for providing different stable upright positions for connector 314.
FIGS. 4A and 4B are cross-sectional side views showing a connector assembly 400 according to an embodiment of the present invention. In this embodiment, a rotatable connector 414 may be supported by a supporting surface 455 that has a stabilizing feature(s), which can allow for multiple upright positions. Note that features of different embodiments shown in the figures may be combined with other features of other embodiments shown in other figures. For example, features of the embodiment of FIGS. 4A and 4B may be combined with features of other embodiments (e.g. embodiments shown FIGS. 3A and 3B).
In FIG. 4A, connector 414 has a curved part 450 (e.g. cylindrical) at the bottom which moves along supporting surface 455. Curved part 450 may be a separate piece or formed integrally with the connector 414 (e.g. with a housing of the connector). In one embodiment, curved part 450 can be a wheel that rotates. In another embodiment, curved part 450 slides. In various embodiments, curved part 450 is coupled with just the side edges of connector 414, just coupled with bottom edges of connector 414, or both. For example, supporting (guiding) surface 455 may be two separate surfaces that exist beyond the edges of connector 414, where curved part 450 attaches or extends beyond a side edge of connector 414.
In one embodiment, curved part 450 slides across surface 455. In another embodiment, curved part 450 rotates as it moves along the surface 450, e.g. when curved part 450 is part of a wheel, cylinder, or sphere. Curved part 450 and supporting surface 455 may be or be part of a rotation mechanism that allows connector 414 to rotate. Outer shell sections 434 a and 434 b or just parts of the outer shell sections 434 a and 434 b (such as edges and surfaces) may also be part of the rotation mechanism.
Supporting surface 455 may have contours, detents, or other such features to provide different upright positions. For example, in FIG. 4A, curved part 450 sits in a trough 455 a of supporting surface 455. As the connector 414 is rotated forward (counterclockwise), the rise in the peak to the right of the trough will oppose such motion. In such embodiments, supporting surface 455 may act as the biasing mechanism or in concert with another biasing mechanism.
As connector 414 rotates under a sufficient force, curved part 450 can move into trough 455 b. Trough 455 b may act as another detent for holding connector 414 in a different upright position than was achieved by trough 455 a. As shown in FIG. 4B, curved part 450 resides in a trough 455 c, which roughly corresponds with connector 414 being fully rotated forward as allowed by the shape of sections 434 a and 434 b of outer shell 434.
Although shown as having 3 troughs in FIGS. 4A and 4B, surface 455 may have more, fewer, or no troughs. Also, the troughs may be at the same height or different heights, e.g., a gradually increasing/decreasing slope. Additionally, supporting surface 455 may continue to increase after trough 455 b (or at least flatten out after the peak), and thus would not have a trough 455 c that corresponds to the full forward rotation. Having such an increased height of supporting surface 455 at the full rotation can provide a greater biasing force to push connector 414 backward (clockwise).
An electrical connection between the rotatable connector and electronics of the docking station may be configured in various ways, as is mentioned above. In one embodiment, a biasing mechanism and the electrical connection may reside in the same plane. Some of these embodiments are now described.
FIG. 5A shows a cross-sectional side view of a rotatable connector 514 that has a biasing mechanism 526 and an electronic connection 524 according to an embodiment of the present invention. In FIG. 5A, electrical connection 524 and biasing mechanism 526 reside at least partly in a same plane. This may be accomplished in a variety of different ways. For example, electrical connection 524 could go through the biasing mechanism 526 or be separated laterally.
In this embodiment, electrical connection 524 couples to connector 514 at a back surface 502 of connector 514 (although it is near the bottom of the connector). In other embodiments, connection 524 may be made on a bottom surface of the connector 514.
FIG. 5A also illustrates an embodiment where the amount of rotation can be controlled by a stop 590. A bottom of connector 514 can be in contact with stop 590, which prevents further rotation in the clockwise direction (e.g. backward). In the embodiment shown, connector 514 is pinned between stop 590 and edge 537 so that further rotation in the clockwise direction is prevented.
FIGS. 5B and 5C show a bottom view of the connector 514, biasing mechanism 526, and electrical connection 524 of FIG. 5A according to an embodiment of the present invention. The bottom surface of connector 514 is shown coupled to electrical connection 524. Electrical connection 524 can be a ribbon cable, although the connection may be accomplished in a different manner. An exterior shape 580 of a body of the docking station is provided as a reference to compare the differences in positions between FIGS. 5B and 5C.
Biasing mechanism 526 can include two separate members: a first biasing member 526 a and a second biasing member 526 b. As one can see, the biasing members 526 a,526 b rest against connector 514 at positions that are outside the edges of connection 524. Having two biasing members at either side can provide for a more uniform force than having just one. Alternatively, the biasing mechanism can be placed in the middle with two electrical connections at the ends. When the bottom of connector 514 is moved, the back end of biasing mechanism 526 is held in place with fixed elements 527.
FIG. 5B shows connector in a first position (e.g. an upright position). As the connector rotates forward, the bottom of connector 514 moves towards the back of the docking station, as shown in FIG. 5C. This movement along with fixed elements 527 causes the length of biasing members 527 to decrease, which increases a biasing force.
In another embodiment, electrical connection 524 can also act as biasing mechanism 526. For example, connection 524 may be flexible to allow movement of connector 514, but have a stiffness, thereby acting as a spring.
The outer shell of the base of the docking station can have various shapes consistent with embodiments of the present invention. For example, FIGS. 6A and 6B show cross-sectional side views of a rotatable connector 614 that pivots about edges of an outer shell having various shapes according to embodiments of the present invention. In FIG. 6A, outer shell 634 has sections 634 a and 634 b disposed next to the front and back sides of connector 614, respectively. The left section 634 a has a top surface 631 a and a bottom surface 633 a. The right section 634 b has a top surface 631 b and a bottom surface 633 b. In FIG. 6A, top surfaces 631 a,631 b are curved while bottom surfaces 633 a,633 b are flat. In FIG. 6B, top surfaces 631 c,631 d have curved surfaces and bottom surfaces 638 c and 638 d are also curved or otherwise non-flat. In other embodiments, just the bottom surfaces 638 c and 638 d may be curved.
In the embodiments of FIG. 6A, sections 634 a,634 b may be formed separately from the rest of the base 639 a and 639 b, e.g., as a trim that fits into a recess in the base. The part of the outer shell having the opening through which the connector rises of any embodiment mentioned herein may also be composed of a trim that fits into a recess of the base. Additionally, the surfaces and points that contact the connector may have various shapes, as is described below.
FIGS. 7A and 7B shows cross-sectional side views of a rotatable connector 714 that pivots about edges of an outer shell 734 having the edges at different heights according to an embodiment of the present invention.
In FIG. 7A, connector 714 is shown fully rotated backward (clockwise as shown). Connector 714 is in contact with an edge 737 b, as well as a surface section 736 b, which is above edge 737 b. Having surface section 736 b allows a surface 731 b to be higher, and also provides a greater surface area for stopping a rotation of connector 714, which can reduce the wear and tear on edge 737 b. In particular, if the upright position is the most frequent position of operation, such durability is more important than the fully forward (counterclockwise) position.
To provide a more regular slope from surface 731 b to a surface 731 a, an edge 737 a of section 734 a of the outer shell can be at a higher height than edge 737 b. As shown, the trend from surface 731 b to surface 731 a is a downward slope. Having a higher edge 737 a can not only provide a consistent slope from surface 731 b to surface 731 a, but also can allow section 734 to be thicker and stronger where it contacts and resists movement of connector 714.
In another embodiment, a surface 736 a may also have an upper section above edge 737 a, in a similar orientation as surface 736 b. As mentioned above, the upper portion of surface 736 a can also provide for greater durability, and also allow for a thicker and stronger surface 734 a. In FIG. 7B, connector 714 is shown fully rotated forward (counterclockwise as shown). Connector 714 is stopped in the rotation by a lower section of surface 736 b that is below edge 737 b and stopped by edge 737 a. In one aspect, connector 714 could rotate further forward, if edge 737 b were lowered in the vertical direction or moved farther from edge 737 b. Having a consistent slope from surface 731 b to surface 731 a can also give the docking station relatively more weight towards the back of the docking station, as the base of the docking station would be thicker towards the back. Since more weight would be toward the back, if there is enough force on the connector in the forward direction, the docking station can then (by design) tip over so that all of the force does not remain on the connector, which might otherwise break the connector.
Some embodiments can also prevent the rotatable connector from breaking by helping the connector to be removed (ejected) from the portable electronic device when the connector is rotated too far. In this manner, the connector will no longer experience the force from a portable electronic device that has been rotated too far, since the portable electronic device will no longer be coupled to the connector. In some embodiments, this ejection can be accomplished by retracting at least a portion of the connector into the body of the docking station.
FIGS. 8A-8C show cross-sectional side views of a rotatable connector 814 that retracts into the docking station during rotation according to an embodiment of the present invention.
FIG. 8A shows the connector fully rotated backward (clockwise) into an upright position, e.g., where a connected portable electronic device can be received by a rear reference surface (not shown) of the docking station. A guide post 850 is coupled to or formed as part of the connector 814. For example, cylindrical rods may be attached to side edges of connector 814. In other embodiments, the guideposts may be rectangular, oblong, or any other suitable geometric shape. A biasing mechanism 826 is used as in other embodiments to bias connector 814 into an upright position.
Guide planes 855 (composed of two surfaces 855 a and 855 b in this embodiment) can guide the motion of the guidepost 850 as connector 814 rotates. This guiding of the motion of the bottom or other part of connector 814 can provide a retraction motion during rotation. Although guide planes 855 are shown parallel and horizontal, other shapes and orientations may be used. For example, the bottom guide plane 855 b may have the same shape as the supporting surface 455 of FIGS. 4A and 4B.
Guide post 850 and the guiding surfaces 855 may provide a retraction mechanism that retracts connector 814 as it rotates away from the vertical. Guide post 850 and guiding surfaces 855 may also be or be part of a rotation mechanism that allows connector 814 to rotate. Outer shell sections 834 a and 834 b or just parts of outer shell sections 834 a and 834 b (such as edges and surfaces) may also be part of the rotation mechanism.
FIG. 8B shows connector 814 rotated to a more vertical orientation. In this position, connector 814 is shown as contacting an edge 837 a of the section 834 a of the outer shell. In one aspect, this position of connector 814 may occur when connector 814 has been rotated forward. When moving backward from this position, connector 814 may contact and pivot about an edge of the section 834 b of the outer shell.
In FIG. 8B, the portion of connector 814 extending above a top surface 831 b of the outer shell has increased relative to the position shown in FIG. 8A. This is because the distance from the bottom guide plane 855 b to the surface 831 b along connector 814, is shorter than in FIG. 8A. The distance is shorter because the connector is more vertical.
Since the portion of connector 814 below top surface 831 b is smaller, more of the connector is above surface 831 b. Thus, the bottom guide plane 855 b can push up connector 814 by keeping the guidepost 850 at the same height. However, as connector 814 rotates forward (counterclockwise) beyond the vertical, more of connector 814 will be below top surface 831 b, and less will be above. This motion effectively retracts connector 814.
FIG. 8C shows connector 814 fully rotated forward (counterclockwise as shown). As connector 814 rotates forward, guidepost 850 moves backward (to the right as drawn), and the angle of connector 814 from the vertical increases. Since guide plane 855 a prevents guidepost 850 from moving closer to surface 831 b, the portion of connector 814 below surface 831 b increases. As the portion of connector 814 below the top surface 8831 b increases, the portion above the top surface 831 b decreases, which causes a retraction of connector 814.
In other words, once connector 814 is rotated past the vertical, the connector 814 is pulled by guide plane 855 a farther into the body of the docking station. If a small enough portion of connector 814 is above top surface 831 b, connector 814 is not able to remain coupled with the portable electronic device, and thus connector 814 can be ejected from the portable electronic device.
Such ejection may be helpful in embodiments where the connector cannot rotate all the way to being horizontal in the forward direction. In such situations, when the connector is fully rotated forward, the connector is vulnerable to breaking by a continuing force in the forward direction. The embodiments of FIGS. 8A-8C can prevent connector 814 from being continually pushed forward by promoting the ejection (disengaging) of connector 814 from the portable device prior to connector 814 reaching the position of full rotation forward.
Embodiments described herein provide docking stations with a connector that couples with a portable electronic device. A connector can move (e.g. rotate) when a forward force is applied, which helps to prevent the connector from breaking. In some embodiments, a biasing mechanism may be used to keep the connector in an upright position. A rear reference surface can be provided to support the electronic device with the connector in the upright position. Additionally, in some embodiments, the connector may retract into the body when rotated forward, thereby promoting ejection from a connected device before strain damages the connector.
In some embodiments, an edge of an outer shell of the dock can act as a pivot for the connector. In such embodiments, the opening through which the connector extends can be smaller, reducing a likelihood of debris falling inside 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.
