Abstract
Description
Technical Field
[0001] This application relates to a handle assembly, particularly a handle assembly applied to the outside of a vehicle door. Background Technology
[0002] The vehicle's handle assembly includes a housing, a handle, a linkage assembly, and an actuator. The handle has an open position and a closed position, and can rotate between the two positions. When the handle is in the closed position, it is flush with the door; when the handle is in the unlocked position, it is above the door surface for easy operation. The actuator drives the linkage assembly to move, thereby moving the handle. Utility Model Content
[0003] Some existing handle assemblies use linear motion actuators to drive the linkage assembly, which can generate relatively high noise.
[0004] To address this problem, this application provides a handle assembly, including: a housing, a handle, a linkage assembly, and a transmission unit. The handle is configured to move relative to the housing and has a closed position and an open position. The linkage assembly connects the handle to the housing and includes a first link. The transmission unit is configured to drive the first link to move a certain distance, thereby moving the handle from the closed position to the open position.
[0005] In the handle assembly described above, the transmission unit is configured to rotate to drive the first link to move in a linear direction.
[0006] As described above, the handle assembly further includes a second link and a third link, one end of each of the second link and the third link being rotatably connected to the handle, and the other end of each of the second link and the third link being rotatably connected to the first link, with a gap between the second link and the third link.
[0007] In the handle assembly described above, the second link is closer to the transmission unit than the third link. The second link is rotatably connected to the housing. When the transmission unit drives the first link to move, the second link rotates relative to the housing to move the handle from the closed position to the open position.
[0008] As described above, in the handle assembly, the first link has a link ramp, and the second link has a contact portion. The link ramp extends obliquely in a direction away from the transmission unit and away from the handle. The link ramp and the contact portion are configured such that when the transmission unit drives the first link to move, the contact portion slides relative to the link ramp, thereby causing the second link to rotate relative to the housing. The contact portion protrudes from the surface of the second link.
[0009] In the handle assembly described above, the inclination angle of the inclined surface of the connecting rod relative to the direction of movement of the first connecting rod ranges from 5° to 80°.
[0010] The handle assembly as described above includes a first reset device disposed between the first link and the housing. The first reset device is configured to apply a spring force toward the first link so that the first link can rotate to drive the handle from the open position back to the closed position.
[0011] The handle assembly as described above further includes a second reset device disposed between the first link and the second link. The second reset device is configured to apply a spring force to the second link, causing the second link to return to its initial position as the handle moves from the open position to the closed position.
[0012] In the handle assembly described above, the first link includes a contact surface facing the transmission part, the contact surface being configured to contact the transmission part; the contact surface is perpendicular to the direction of movement of the first link.
[0013] The handle assembly described above further includes an actuator, the transmission part including an eccentric cam, and the actuator capable of driving the eccentric cam to rotate.
[0014] Specifically, the actuator is a rotary actuator, which has low noise.
[0015] The handle assembly of this application includes a handle, a linkage assembly, a first reset device, a second reset device, a transmission part, and an actuator. The transmission part can be driven to rotate by the actuator and can drive the linkage assembly to move, thereby moving the handle from the closed position to the open position. The linkage assembly includes a first link, a second link, and a third link, with each of the second and third links connected at both ends to the handle and the first link, respectively. The transmission part can rotate to drive the first link to move in a linear direction, and the movement of the first link can drive the second link to rotate, thereby moving the handle from the closed position to the open position. The first reset device is disposed between the housing and the second link, and the second reset device is disposed between the first and third links. The first link has a linkage ramp, and the second link has a contact part.
[0016] In this application, the transmission unit drives the third linkage to move linearly to open the handle, resulting in a simple structure with few parts. The cooperation between the linkage's inclined surface and the contact part reduces the force required for the actuator to drive the handle. Attached Figure Description

Figure 2A and Figure 2B As shown, the housing 101 includes a main body 201 and a bottom cover 202. The main body 201 has a side wall 211, a bottom 212, and a top 213. The side wall 211, bottom 212, and top 213 form a cavity 205. The cavity 205 has a bottom opening 251 and a top opening 252. The cavity 205 can accommodate components such as the handle 102 and the linkage assembly 103. The bottom cover 202 is used to close the bottom opening 251 to facilitate the installation of components such as the handle 102 and the linkage assembly 103. The handle 102 can move relative to the housing 101, thereby extending out of the top opening 252 to reach an open position, or approximately flush with the top opening 252 to reach a closed position. A limiting portion 288 extending along the length direction of the handle assembly is provided in the side wall 211 for cooperating with the first linkage 131.
[0055] Figure 3 yes Figure 1B A perspective view of the handle 102. (See image below.) Figure 3 As shown, the handle 102 includes a handle panel 302 and a handle connecting portion 303. The handle panel 302 is generally a strip-shaped flat plate with an upper surface 321a and a lower surface 321b. The handle connecting portion 303 includes a front section 381, a middle section 382, and a rear section 383. The middle section 382 extends generally parallel to the handle panel 302. The front section 381 and the rear section 383 extend from both ends of the middle section 382 toward the handle panel 302 and connect to the lower surface 321b of the handle panel 302. Thus, the handle panel 302 and the handle connecting portion 303 form a hollow space 330, which is used to facilitate the operator to insert their hand into the hollow space 330 to operate the handle 102. The handle connecting portion 303 includes a first connecting end 331 and a second connecting end 332. The first connecting end 331 and the second connecting end 332 are respectively provided with shaft mounting mating parts 334 and 335 for mounting shafts. The handle connector 303 is pivotally connected to the linkage assembly 103 via a shaft. The shape of the handle panel 302 matches the shape of the housing 101 and can cover the top opening 252.
[0056] Figure 4A yes Figure 1B A 3D view of the first link 131 in the diagram. Figure 4B yes Figure 4A Side view of the first link 131. Combined with... Figure 4A and Figure 4B as well as Figure 1BAs shown, the first link 131 includes a head 411 and a rod portion 412. The rod portion 412 is generally a strip-shaped flat plate and extends along the length direction L and width direction W of the handle assembly 100. The rod portion 412 has an upper side 421a facing the handle 102 and a lower side 421b facing the bottom 212 of the housing. The head 411 extends from one end of the rod portion 412 toward the handle 102 along the thickness direction D of the handle assembly, thereby being higher than the upper side 421a of the rod portion. The head 411 is disposed at the end of the rod portion 412 near the transmission part 104. The head 411 has a contact surface 441 and a connecting rod ramp 442, wherein the contact surface 441 is located on the side facing the transmission part 104, and the connecting rod ramp 442 is located on the side away from the transmission part 104 (see [reference]). Figure 1B , Figures 8A-8C The contact surface 441 extends approximately along a direction perpendicular to the rod portion 412, that is, along the thickness direction D of the handle assembly. The connecting rod ramp 442 extends obliquely from the upper side 421a of the rod portion 412 along the thickness direction D of the handle assembly toward the contact surface 441. Viewed from the side of the first connecting rod 131, the cross-section of the head 411 is approximately trapezoidal.
[0057] The rod portion 412 has a hollow portion 469 extending through the upper side 421a and the lower side 421b to accommodate the second connecting rod 132. The rod portion 412 also has a groove 471 and a reset device mounting portion 472 disposed in the groove 471. The groove 471 extends from the end of the rod portion 412 away from the head 411 toward the head 411. The reset device mounting portion 472 is disposed in the groove 471, with its two ends connected to a pair of inner sidewalls 481 and 482 of the groove 471, and has a gap between it and the bottom wall 483 of the groove. The reset device mounting portion 472 is used to mount the second reset device 109 (see...). Figure 1B One end of the rod 412. A pair of protrusions 491 and 492 are provided on both sides of the rod 412. The pair of protrusions 491 and 492 cooperate with the limiting part 288 of the housing 101 to limit the movement direction of the first connecting rod 131.
[0058] Figure 5A yes Figure 1B A 3D view of the second link in the middle. Figure 5B yes Figure 1B Side view of the second link in the middle. (See image) Figure 5A and Figure 5B As shown, the second link 132 includes a first link portion 511, a second link portion 512, and a contact portion 513. The proximal ends of the first link portion 511 and the second link portion 512 are connected to each other, forming an included angle. The distal ends of the first link portion 511 and the second link portion 512 are respectively provided with a first shaft 561 and a second shaft 562 of the second link. The second link 132 is rotatably connected to the housing 101 via the first shaft 561 and rotatably connected to the handle 102 via the second shaft 562.
[0059] The first rod portion 511 has a first side 541a and a second side 542b disposed opposite to each other. A contact portion 513 extends from the second side 542b and protrudes from the surface of the second side 542b. The contact portion 513 gradually decreases in size in the direction away from the second side 542b, and a contact end 556 is formed at the distal end of the contact portion 513. The contact end 556 is capable of contacting the inclined surface 442 of the connecting rod.
[0060] Figure 6 yes Figure 1B A three-dimensional diagram of the third link, as shown below. Figure 6 As shown, the third link 133 has a first shaft 661 and a second shaft 662 at its two ends, and is rotatably connected to the handle 102 via the second shaft 662. The third link 133 also includes a recess 655 near the first shaft 661 for mounting the second reset device 109 (see [reference]). Figure 1B The third link 133 is connected to the first link 131 via the second reset device 109.
[0061] Figure 7 for Figure 1B A three-dimensional view of the central transmission unit, such as Figure 7 As shown, the transmission unit 104 is an eccentric cam 701. The eccentric cam 701 has a central shaft 711 and a transmission surface 722. The actuator 105 can drive the eccentric cam 701 to rotate around the central shaft 711. The transmission surface 722 is arranged around the central shaft 711 and extends from a first end 741a to a second end 741b. In the extension direction from the first end 741a to the second end 741b, the distance of the transmission surface 722 from the central shaft 711 gradually increases. The transmission surface 722 can contact the contact surface 441 of the first connecting rod 131.
[0062] Figure 8A yes Figure 1A The center handle assembly is hidden behind the housing and is in a closed side view. Figure 8B yes Figure 1A Side view of the center handle assembly hidden in the housing and in the middle position. Figure 8C yes Figure 1A Side view of the center handle assembly in the open position after it is hidden in the housing.
[0063] like Figures 8A-8C As shown, the two ends of the handle 102 are fitted with mating parts 334 and 335 via shafts (see...). Figure 3The first link 131 is connected to one end of the second link 132 and the third link 133, respectively, and the other end of the second link 132 and the third link 133 is connected to both ends of the first link 131. Thus, the handle 102, the second link 132, the third link 133, and the first link 131 form a roughly quadrilateral structure. The bottom of the first link 131 abuts against the bottom 212 of the housing 101 (the housing is not shown in figures 8A-8C, see [reference]). Figure 2A On the handle assembly, the first link 131 and the bottom 212 of the housing 101 both extend along the length direction L. The first link 131 cooperates with the housing 101 and can move linearly along the length direction L. The contact portion 513 of the second link 132 abuts against the connecting ramp 442 of the first link 131, and the second link 132 is pivotally connected to the housing 101 via the second link first shaft 561. A first reset device 108 is also provided between the second link first shaft 561 and the housing 101. In one embodiment of this application, the first reset device 108 is a torsion spring, used to provide elastic force to the second link 132 so that the second link 132 can return to its initial position, that is, the position where the second link 132 is when the handle 102 is in the closed position. The second reset device 109 is disposed between the third link 133 and the first link 131. The second reset device provides tension between the third link 133 and the first link 131, so that the third link can return to its initial position, that is, the position where the second link 132 is when the handle 102 is in the closed position. In one embodiment of this application, the second reset device 109 is a spring, and the two ends of the second reset device 109 are respectively connected to the reset device mounting part 472 (see...). Figure 4A ) and the first shaft of the second link 561 (see Figure 5A The transmission unit 104 is disposed on one side of the first connecting rod 131 and contacts the contact surface 441 of the first connecting rod 131. The actuator is connected to the transmission unit 104 and is capable of driving the transmission unit 104 to rotate.
[0064] Combining 8A and Figure 1A As shown, when the handle 102 is in the closed position, the handle 102 is housed within the housing 101, and the handle panel 302 of the handle 102 is approximately flush with the top opening 252 of the housing 101. Figure 8A As shown, the first reset device 108 applies a spring force to the second connecting rod 132, causing the second connecting rod 132 to have a clockwise rotational tendency, thereby enabling the second connecting rod 132 to apply a force to the first connecting rod 131 in the direction of the transmission part 104. At this time, the portion of the transmission surface 722 of the transmission part 104 that is closer to the central axis 711 contacts the contact surface 441 of the first connecting rod 131. That is, the first connecting rod 131 is in a position closer to the central axis 711. A portion of the second connecting rod 132 is located in the hollow portion 469 of the first connecting rod 131 (see...). Figure 4AIn the middle, the second reset device 109 applies a pulling force to the third link, so that the third link 133 is in a position approximately parallel to the first link 131.
[0065] exist Figure 8A In the closed position shown, the extension direction of the first rod portion 511 of the second link 132 is approximately parallel to the extension direction of the connecting rod inclined surface 442 of the first link 131.
[0066] like Figure 8B As shown, when the handle 102 needs to be opened, the actuator drives the transmission unit 104 to rotate clockwise. The contact point between the transmission surface 722 of the transmission unit 104 and the contact surface 411 of the first connecting rod 131 moves away from the central axis 711, thereby pushing the first connecting rod 131 to move away from the central axis 711 along the length L of the handle assembly. The first connecting rod 131 pushes the second connecting rod 132 to move through the connecting rod inclined surface 442. The contact portion 513 of the second connecting rod 132 slides relative to the connecting rod inclined surface 442, and the second connecting rod 132 rotates counterclockwise relative to the housing 101. The second axis 562 of the second connecting rod moves away from the first connecting rod 131, thereby driving the handle 102 away from the closed position. During the above movement, the handle 102 extends from the top opening 252 of the housing 101, and its handle panel 302 is approximately parallel to the top opening 252 of the housing 101.
[0067] Figure 8C The open position of the handle is shown. Figure 8B At the intermediate position shown, the actuator drives the transmission unit 104 to rotate further clockwise, achieving the following: Figure 8C As shown in the diagram. Driven by the actuator, the transmission unit 104 pushes the first link 131 to continue moving along the length direction L of the handle assembly away from the central axis 711, while the second link 132 continues to rotate counterclockwise. During this movement, in the thickness direction D of the handle assembly, the second axis 562 of the second link exceeds the first axis 561 of the second link and moves a small distance away from the first link 131 or remains stationary. In the length direction L of the handle assembly, the second axis 562 of the second link moves a certain distance towards the transmission unit 104. The first link 131 pushes the third link 133 to move, and the second axis 662 of the third link continues to move away from the first link 131. During the aforementioned movement, in the thickness direction of the handle assembly, the movement distance of the second shaft 662 of the third link is greater than the movement distance of the second shaft 562 of the second link, so that the second end 332 of the connecting part of the handle 102 is higher than the first end 331 of the connecting part, and the handle panel 302 is tilted relative to the top opening 252 of the housing to facilitate the operator's operation, and the handle 102 reaches the open position.
[0068] When the handle needs to return from the open position to the closed position, the actuator drives the transmission unit to rotate counterclockwise. Under the elastic force of the first reset device, the first link moves towards the central axis and returns to its initial position. At the same time, the second reset device drives the third link to move back to its initial position.
[0069] During the movement of the handle from the closed position to the open position, the first link moves a certain distance along a straight line. This means that each part of the first link has a displacement relative to the housing compared to its initial and final positions. The first link pushes the second link through the inclined plane of the link, converting the force along the handle's length L into a force perpendicular to the inclined plane. This force perpendicular to the inclined plane acts on the second link, causing it to rotate. Since the force perpendicular to the inclined plane is greater than the force along the handle's length L, the actuator only needs to apply a smaller force to rotate the second link.
[0070] The thrust acting on the second link is related to the angle of the link's inclined plane. In one embodiment of this application, the angle between the inclined plane and the direction of motion of the first link is 5° to 80°. In another embodiment of this application, the angle between the inclined plane and the direction of motion of the first link is 30° to 60°.
[0071] In this application, the handle is opened by an actuator that drives the transmission unit. The actuator is a rotary actuator located on one side of the handle, resulting in lower noise compared to a linear actuator. The first link pushes the second link via a connecting rod ramp. No shaft is needed between the first and second links, simplifying the structure and making it easy to manufacture. Furthermore, the ramp design allows the actuator to provide only a small driving force.
