Detailed Implementation

[0018] Various specific embodiments of this application will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although directional terms such as "front," "rear," "upper," "lower," "left," "right," "top," and "bottom" are used in this application to describe various exemplary structural parts and elements, their use is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these directional terms are for illustrative purposes only and should not be considered as limiting.

[0019] Figure 1 An exploded view of a handle device 100 according to a first embodiment of this application.

[0020] like Figure 1 As shown, the handle assembly 100 includes a handle base 102, a handle 116, a first linkage arm 108, a connecting rod 110, a second linkage arm 112, and a drive device 104. The handle 116 has an extended position and a retracted position relative to the handle base 102, and is capable of translating between the retracted and extended positions. The first linkage arm 108 is rotatably connected to the handle 116 at its first end 108a and rotatably connected to the handle base 102 via a pivot 132 at its second end 108b. The first linkage arm 108 can rotate relative to the handle base 102 under the drive of the drive device 104. The second linkage arm 112 is rotatably connected to the handle 116 at its first end 112a and rotatably connected to the first end 110a of the connecting rod 110 at its second end 112b. The connecting rod 110 is linearly movably connected to the handle seat 102, and its second end 110b is operably connected to the first linkage arm 108 so as to move linearly under the drive of the first linkage arm 108 when the first linkage arm 108 is driven to rotate. Thus, the handle 116, the first linkage arm 108, the connecting rod 110, and the second linkage arm 112 together form a four-bar linkage mechanism for realizing the unfolding and retraction of the handle 116 relative to the handle seat 102.

[0021] Still as Figure 1 As shown, the connecting rod 110 has a pin 114 at its second end 110b for receiving in the arcuate groove 204 of the first connecting rod arm 108 (see details). Figure 2A-2B The first linkage arm 108 can move within the arcuate groove 204, thereby driving the connecting rod 110 to move linearly. The linear movement of the connecting rod 110 drives the second linkage arm 112 to move. Under the combined action of the first linkage arm 108 and the second linkage arm 112, the handle 116 can be translated from the retracted position to the extended position. Limiting devices are provided on the handle seat 102 and the connecting rod 110 for linearly movably connecting the connecting rod 110 to the handle seat 102. In some embodiments, the limiting device includes a slide rail disposed on one of the handle seat 102 and the connecting rod 110, and a slider disposed on the other of the handle seat 102 and the connecting rod 110.

[0022] In the illustrated embodiment, the limiting device 122 includes a first slide rail 122a and a second slide rail 122b disposed on the handle base 102, and a first slider 124a and a second slider 124b disposed on the connecting rod 110. The first slider 124a is positioned near the first end 110a of the connecting rod 110, and the second slider 124b is positioned near the second end 110b of the connecting rod 110. The first slider 124a and the second slider 124b are respectively housed in the first slide rail 122a and the second slide rail 122b, so that the connecting rod 110 can move linearly relative to the handle base 102. As those skilled in the art will appreciate, the limiting device is not limited to the above-described configuration.

[0023] Continue as Figure 1 As shown, the drive device 104 includes an actuator 105 and a transmission member 106, the actuator 105 being capable of driving the transmission member 106 to rotate. The transmission member 106 is connected, for example, to the output shaft of the actuator 105. The first linkage arm 108 includes a joint 111, and the transmission member 106 is operatively connected to the joint 111 of the first linkage arm so that the actuator 105 can drive the first linkage arm 108 to rotate via the transmission member 106. The transmission member 106 and the joint 111 of the first linkage arm 108 form a speed reduction transmission mechanism. The joint 111 of the first linkage arm 108 includes a protrusion 141 and a wheel 142 rotatably disposed on the protrusion 141. The wheel 142 is, for example, a roller. The rotation of the wheel 142 causes a rolling contact to be formed between the joint 111 of the first linkage arm 108 and the transmission member 106.

[0024] Figure 2A-2B for Figure 1 The front view of the handle assembly is shown to illustrate the unfolding process of the handle. Figure 2A This is a front view of the handle assembly with the handle in the retracted position. Figure 2B This is a front view of the handle assembly with the handle in the extended position. To more clearly show the position and connection relationship of the various components of the handle assembly, the handle base 102 is omitted in the figure.

[0025] like Figure 2A-2B As shown, the first link arm 108 is provided with an arc-shaped groove 204, and the pin 114 on the connecting rod 110 is accommodated in the arc-shaped groove 204 and can move within the arc-shaped groove 204. The connecting rod 110 and the first link arm 108 are operably connected by the pin 114 and the arc-shaped groove 204, so that the first link arm 108 can drive the connecting rod 110 to move linearly. As those skilled in the art will know, the first link arm 108 driving the connecting rod 110 is not limited to the above-described engagement of the arc-shaped groove 204 and the pin 114. In other embodiments, a cam with a specific curvature can be provided on the first link arm 108, and the rotation of the cam can drive the connecting rod 110 to move linearly.

[0026] Still as Figure 2A-2B As shown, the transmission member 106 includes a transmission portion and a holding portion adjacent to each other in its circumferential direction. The transmission member 106 drives the first linkage arm 108 to rotate through the engagement of the transmission portion with the engagement portion 111 of the first linkage arm 108, and holds the handle 116 in the extended position through the engagement of the holding portion with the engagement portion 111 of the first linkage arm 108. Figure 2B As shown in the enlarged view, the transmission part of the transmission member 106 includes a cam surface 206, and the holding part of the transmission member 106 includes an arc surface 207. The rotation radius r1 of the cam surface 206 gradually increases counterclockwise in the figure. The cam surface 206 connects to the arc surface 207 at its end with the largest rotation radius r1 (i.e., point A), and the rotation radius r2 of the arc surface 207 is approximately the same as the maximum rotation radius of the cam surface 206. Therefore, when the cam surface 206 of the transmission member 106 contacts the wheel 142 of the first link arm 108, the clockwise rotation of the transmission member 106 in the figure can drive the first link arm 108 to rotate. However, when the transmission member 106 rotates to the point where the arc surface 207 contacts the wheel 142 of the first link arm 108, the rotation of the transmission member 106 no longer drives the first link arm 108 to rotate. In other words, when the arc surface 207 of the transmission component 106 contacts the joint portion 111 of the first linkage arm 108, the transmission component 106 can rotate, but it cannot drive the first linkage arm 108 to move. Instead, the arc surface 207 keeps the handle 116 in the extended position.

[0027] like Figure 2A As shown, the handle 116 is in the retracted position, and the cam surface 206 is in contact with the wheel 142 of the engagement portion 111 of the first linkage arm 108. When the drive unit 104 drives the handle 116 to move from the retracted position to the extended position, the transmission member 106 moves downward under the drive of the actuator 105. Figure 2A The cam rotates clockwise, driving the first linkage arm 108 to rotate via the cam surface 206. The first linkage arm 108 engages with the pin 114 on the connecting rod 110 via the arcuate groove 204 on it, driving the connecting rod 110 to move linearly relative to the handle seat. During this linear movement, the connecting rod 110 pushes the second linkage arm 112 to move. Thus, under the combined action of the first linkage arm 108 and the second linkage arm 112, the handle 116 translates approximately in the direction indicated by arrow D in the figure toward the unfolded position.

[0028] like Figure 2B As shown, as the transmission component 106 rotates, when the position of the transmission component 106 in contact with the wheel 142 changes from the cam surface 206 to the arc surface 207 (for example, at point A), the handle 116 is in the state of just reaching the unfolded position.

[0029] When handle 116 reaches such Figure 2BAfter being deployed, the wheel 142 of the engagement portion 111 of the first link arm 108 contacts the arc surface 207 of the transmission member 106. Since the radius of rotation r2 of the arc surface 207 of the transmission member 106 remains constant, even if the transmission member 106 continues to rotate, the actuator 105 cannot continue to drive the first link arm 108 to rotate via the transmission member 106. Correspondingly, the connecting rod 110 and the second link arm 112 also cease to move. Therefore, subsequent rotation of the transmission member 106 will not change the position of the handle 116, but will instead hold the handle 116 in the deployed position via the arc surface 207, as shown. Figure 2C As shown.

[0030] Figures 3A-3C A second embodiment of this application is shown, wherein Figure 3A This is a front view of the handle assembly with the handle in the retracted position. Figure 3B This is a front view of the handle assembly when the handle has just reached the extended position. Figure 3C This is a front view of the handle assembly when the handle is held in the extended position. The handle assembly 300 in the second embodiment differs from the handle assembly 100 in the first embodiment in that the structure of the transmission member and the structure of the first linkage arm portion cooperating with the transmission member in the handle assembly 300 are different from the corresponding structures on the handle assembly 100. The same parts will not be described again.

[0031] like Figures 3A-3C As shown, the handle device 300 has a transmission member 306 and a first linkage arm 308 that differ from those in the first embodiment. The transmission part of the transmission member 306 includes a first partial gear 303. The first partial gear 303 is not a complete gear; it has teeth in only one section in the circumferential direction, while another section is toothless. The first partial gear 303 is generally fan-shaped.

[0032] The retaining portion of the transmission member 306 includes a locking lever 324, which is connected to and rotates synchronously with the first partial gear 303. The locking lever 324 is aligned with the toothless area of ​​the first partial gear 303. The locking lever 324 includes a locking pin 328 located at its distal end.

[0033] The engagement portion 311 of the first linkage arm 308 includes a second gear 314, which is not a complete gear but only has a segment of teeth. The second gear 314 is generally fan-shaped. A locking groove 326 is provided on the second gear 314, and the locking pin 328 on the locking rod 324 can move in and out of the locking groove 326. The shape of the locking groove 326 is designed to match the movement trajectory of the locking pin 328 as the locking rod 324 rotates. The locking groove 326 is, for example, an arc-shaped groove.

[0034] When the first gear 303 meshes with the second gear 314, the actuator 105 can drive the first linkage arm 308 to rotate via the transmission member 306. When the first gear 303 disengages from the second gear 314, a portion of the locking rod 324 (i.e., the locking pin 328) enters the locking groove 326, and the actuator 105 cannot drive the first linkage arm 308 to rotate via the transmission member 306.

[0035] like Figure 3A As shown, the handle 116 is in the retracted position, and the first gear 303 and the second gear 314 are meshed. When the drive device 104 drives the handle 116 from the retracted position to the extended position, the transmission member 306 moves downward under the drive of the actuator 105. Figure 3A The first linkage arm 108 rotates clockwise, driving the second linkage arm 314 to rotate via the first gear 303. The first linkage arm 108, through the engagement of its arcuate groove 204 with the pin 114 on the connecting rod 110, drives the connecting rod 110 to move linearly relative to the handle seat. During this linear movement, the connecting rod 110 pushes the second linkage arm 112, causing it to move. Thus, under the combined action of the first linkage arm 108 and the second linkage arm 112, the handle 116 translates approximately in the direction indicated by arrow D in the figure towards the unfolded position.

[0036] like Figure 3B As shown, as the transmission component 306 rotates, when the first gear 303 and the second gear 314 disengage, the handle 116 is in the state of just reaching the unfolded position, and the locking pin 328 begins to enter the locking groove 326.

[0037] Arrive at handle 116 Figure 3B After the lock is in the extended position, because the shape of the locking groove 326 matches the movement trajectory of the locking pin 328 as it rotates with the locking rod 324, the movement of the locking pin 328 in the locking groove 326 will not cause the first linkage arm 308 to rotate. Correspondingly, the connecting rod 110 and the second linkage arm 112 also cease to move. Therefore, subsequent rotation of the transmission member 306 will not change the position of the handle 116, but will instead hold the handle 116 in the extended position via the locking pin 328, as shown. Figure 3C As shown.

[0038] Figures 4A-4B The use case of the handle device is shown, in which, Figure 4A This is a schematic diagram of a vehicle with handles. Figure 4B This is a diagram of a car door.

[0039] like Figures 4A-4BAs shown, this application also protects a vehicle 400 having a door 402, on which a handle cavity 404 is provided for mounting the aforementioned handle device 100 / 300. When not in use, the handle 116 of the handle device is in a retracted position, with the outer surface 412 of the handle flush with the outer surface of the door 402. When an opening operation is required, the handle 116 can be driven from the retracted position to... Figure 4B The extended position shown allows the user to pull handle 116.

[0040] The structural design of the handle device in this application allows the connecting rod, which is directly driven by the first linkage arm of the drive mechanism, to move linearly during the handle unfolding process. The operating space required for the movement of the components in the handle device is small, thus the structure of the handle device is more compact and the movement of the handle is more stable.

[0041] Furthermore, the handle device of this application, by setting the transmission component of the drive mechanism, allows the actuator of the drive mechanism to not drive the first linkage arm to rotate at its drive end (i.e., the stage from deceleration to complete stop), thereby avoiding the tolerance of the actuator drive end during the unfolding process of the handle, making the unfolding distance of the handle more accurate and consistent each time.

[0042] Furthermore, the transmission component of the handle device and the joint on the first linkage arm together form a speed reduction mechanism, which can provide a large driving force to the handle.

[0043] Although this application has been described with reference to examples of embodiments outlined above, various alternatives, modifications, variations, improvements, and / or substantially equivalents, whether known or currently or soon to be foreseen, will likely be apparent to those skilled in the art. Furthermore, the technical effects and / or technical problems described herein are exemplary and not limiting, and the disclosures herein may be used to solve other technical problems and have other technical effects and / or can solve other technical problems. Therefore, the examples of embodiments of this application as set forth above are intended to be illustrative and not limiting. Various changes can be made without departing from the spirit or scope of this application. Therefore, this application is intended to include all known or previously developed alternatives, modifications, variations, improvements, and / or substantially equivalents.
