Abstract
Description
Technical Field
[0001] This application relates to a handle assembly, particularly a handle assembly used in a concealed vehicle door. Background Technology
[0002] The concealed handle assembly has an outer surface that is roughly flush with the door panel, making the door panel surface smooth and aesthetically pleasing. To open the door, the operating part of the handle must first be protruded from the door panel by a drive mechanism or external force, making it easy for the operator to grip. The operator then applies force to the operating part to open the door panel. Summary of the Invention
[0003] When opening a door panel using a concealed handle, the handle needs to protrude from the door panel surface, a process that requires the application of external force. This application provides a handle assembly that reduces the external force required in this process.
[0004] The handle assembly provided in this application includes:
[0005] Handle base;
[0006] A rocker arm, which is connected to the handle seat via a rocker arm shaft and is capable of rotating around the rocker arm shaft;
[0007] The handle body is connected to the handle seat via a handle body shaft and is rotatable around the handle body shaft, so that the handle body has an initial position, a first open position and a second open position, wherein the handle body can drive the rocker arm to rotate, and the rocker arm can drive the handle body to rotate;
[0008] A first elastic device is disposed between the rocker arm and the handle seat, and the first elastic device is configured to provide a first deflection force relative to the handle seat to the rocker arm during the rotation of the handle body from an initial position to a first open position and from the first open position to a second open position.
[0009] A second elastic device is configured to provide a second deflection force relative to the handle seat to the rocker arm during the rotation of the handle body from the initial position to the first open position. The second deflection force is opposite in direction to the first deflection force provided by the first elastic device, so as to partially counteract the first deflection force applied to the rocker arm.
[0010] Furthermore, the handle assembly also includes:
[0011] A limiting device is disposed on the handle seat, and the limiting device is configured to: separate from the second elastic device during the movement of the handle body from the initial position to the first open position, so that the second elastic device can provide a second deflection force relative to the handle seat to the rocker arm; and engage with the second elastic device when the handle body rotates from the first open position to the second open position, thereby preventing the second elastic device from continuing to provide a second deflection force to the rocker arm.
[0012] Furthermore, the second elastic device is a second torsion spring, which has a first arm and a second arm. The first arm of the second torsion spring is connected to the handle body or the rocker arm, and the second arm is connected to the handle seat.
[0013] The limiting device can engage with the first arm to separate the second elastic device from the rotational movement of the handle body or the rocker arm, thereby preventing the second elastic device from continuing to provide a second deflection force to the rocker arm.
[0014] Furthermore, the limiting device is a limiting protrusion or a limiting claw extending from the handle seat.
[0015] Furthermore, the first arm of the second torsion spring is connected to the handle body, the handle body is provided with a receiving groove, the receiving groove has a certain length, and the first arm of the second elastic device can move within the receiving groove.
[0016] Furthermore, the elastic force of the second elastic device is less than that of the first elastic device.
[0017] Furthermore, the handle assembly also includes:
[0018] A slider is used to push the transmission part of the handle body, causing the handle body to rotate from the initial position to the first open position.
[0019] Furthermore, the handle assembly also includes:
[0020] A driving device is provided, which is capable of driving the handle body to rotate around the handle body axis, so that the handle body rotates from the initial position to the first open position.
[0021] Furthermore, the extending direction of the rocker arm shaft and the extending direction of the handle body shaft form an angle.
[0022] Furthermore, the handle seat has opposing front and rear sides, the front side has a handle body cavity, the handle body is at least partially accommodated in the handle body cavity, and a portion of the handle body is located on the rear side of the handle seat;
[0023] The rocker arm is connected to the rear side of the handle base via the rocker arm shaft.
[0024] The handle assembly provided in this application requires only minimal power to trigger the handle body to protrude from the door panel for operator operation. When the handle body protrudes from the door panel driven by a motor, the motor only needs to provide a small amount of power to the handle, reducing motor losses. When the handle body protrudes from the door panel manually, it requires less effort from the operator. Attached Figure Description

[0048] Various specific embodiments of the present invention will now be described with reference to the accompanying drawings, which form part of this specification. It should be understood that although terms indicating direction, such as "front," "rear," "upper," "lower," "left," and "right," are used herein to describe various exemplary structural parts and elements, their use is merely for ease of description and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed herein can be arranged in different orientations, these terms indicating direction are illustrative only and should not be considered limiting.
[0049] Figure 1A This is a front view of a handle assembly 100 according to an embodiment of this application. Figure 1B yes Figure 1A The diagram shown is an exploded view of the handle assembly 100. Figure 1C yes Figure 1A The rear view of the handle assembly shown below will be combined with... Figure 1A-1C This section describes the structure of the handle assembly 100. The handle assembly 100 is installed on the vehicle door and is used to unlock and open the door. When the handle assembly 100 is installed in place on the vehicle door... Figure 1A The front of the handle assembly shown faces the outside of the door, while Figure 1C The back of the handle assembly shown faces the inside of the door.
[0050] like Figure 1A-1C As shown, the handle assembly 100 includes a handle base 101, a handle body 102, a rocker arm 104, and a slider 103. The handle body 102 is connected to the handle body shaft 901 (see...). Figures 9A-9CA rocker arm 104 is mounted on the handle base 101 and is rotatable relative to the handle base 101 about a handle body shaft 901. The handle body shaft 901 can be a separate shaft, or it can be fixedly connected to the handle body 102, or fixedly connected to the handle base 101. A rocker arm 104 is connected to the back of the handle base 101 via a rocker arm shaft 132 and is rotatable relative to the handle base 101 about the rocker arm shaft 132. In this embodiment, the rocker arm shaft 132 is integrally formed with the handle base 101. Of course, in other embodiments, the rocker arm shaft 132 can also be a separate shaft, or an shaft integrally formed with the rocker arm 104. One end of the rocker arm 104 is connected to a latch (not shown in the figure) via a locking wire 140, so that when the rocker arm 104 rotates, the locking wire 140 can pull the latch to unlock. A slider 103 is mounted on the handle base 101. The slider 103 can drive the handle body 102 to rotate under the drive of the motor 105. When the handle body 102 rotates to a certain position, it can drive the rocker arm 104 to rotate, thereby unlocking the door. This will be described in detail later. The handle assembly 100 also includes a first torsion spring 108 and a second torsion spring 109. The first torsion spring 108 is used to provide a first deflection force required for the handle body 102 and the rocker arm 104 to reset. The first torsion spring 108 is disposed between the rocker arm 104 and the handle seat 101, and the second torsion spring 109 is disposed between the handle body 102 and the handle seat 101. During the rotation of the handle body 102 in the opening operation, the rocker arm 104 drives the first torsion spring 108 to twist, accumulating the first deflection force for reset. The second torsion spring 109 is used to provide a second deflection force for the rocker arm 104 relative to the handle seat 101. The direction of the second deflection force applied to the rocker arm 104 is opposite to the direction of the first deflection force, and is used to counteract part of the first deflection force in the first stage of the rotation process of the handle body 102 in the opening operation. The process of opening the door lock using the handle assembly 100 will be described in detail below.
[0051] In some embodiments, the first torsion spring 108 and the second torsion spring 109 form the first elastic device and the second elastic device, respectively. However, in other embodiments, the first elastic device and the second elastic device may be other types of elastic devices, not limited to torsion springs, as long as they can provide the required deflection force. In some embodiments, a trigger area may be provided on the surface of the front side of the handle body 102, and the operator can trigger the process of opening the door lock by triggering the area.
[0052] Figure 2A yes Figure 1B The perspective view of the handle seat 101 in the handle assembly 100 shown is a view taken from the front side 211 of the handle seat 101. Figure 2B yes Figure 2A The perspective view of the handle base 101 shown here, from another angle, shows the handle base 101 from the rear side 212. Figure 2C This is a perspective view of another embodiment of the handle base. (See diagram below.) Figure 2A As shown, the front side 211 of the handle base 101 is provided with a handle body cavity 217 for accommodating the handle body 102. The handle body cavity 217 is formed by a cavity sidewall 234 and a cavity bottom 232. The top end of the cavity sidewall 234 forms an inlet edge 230, and the bottom end of the cavity sidewall 234 is connected to the cavity bottom 232. The handle body cavity 217 is configured to have a certain depth, such that when the handle body 102 is accommodated in the handle body cavity 217 and is in its initial position, the outer surface of the handle body 102 is slightly higher than the inlet edge 230. The cavity bottom 232 is provided with a hollow portion 219, which communicates with the handle body cavity 217. The cavity sidewall 234 is annular and has a pair of parallel upper sidewalls 251 and lower sidewalls 252. A pair of handle body shaft mounting portions 226 are provided opposite to each other on the upper sidewalls 251 and lower sidewalls 252 for mounting the handle body shaft 901. The front side 211 of the handle base 101 is also provided with a slider channel 221 for accommodating the slider 103 and defining the movement path of the slider 103. The front side 211 of the handle base 101 also has a motor mounting part 225 for mounting the motor 105. The motor mounting part 225 is disposed adjacent to the slider channel 221, and the opening of the slider channel 221 faces the motor mounting part 225, so that after the motor 105 is mounted on the motor mounting part 225, the motor 105 can directly push the slider 103 accommodated in the slider channel 221 to move.
[0053] Handle base 101 includes a limiting device, such as Figure 2A-2B As shown, the limiting device is a limiting protrusion 201 extending from the upper edge 280 of the hollow portion 219 toward the rear side of the handle base 101, which is used to engage with the second torsion spring 109. The handle base 101 also includes a support protrusion 205 extending from the upper edge 280 of the hollow portion 219 toward the rear side of the handle base 101. One side of the support protrusion 205 is connected to the limiting protrusion 201, but the height of the support protrusion 205 relative to the upper edge 280 of the hollow portion 219 is lower than the height of the limiting protrusion 201, thereby forming a step between the support protrusion 205 and the limiting protrusion 201. A second torsion spring engaging portion 215 is formed on the side edge of the limiting protrusion 201 near the support protrusion 205, which is used to contact or separate from the second torsion spring 109. Figure 2CAs shown, in other embodiments, the limiting protrusion 201 can be other forms of limiting device, such as a claw 208 extending from the handle base 101. The claw 208 has a base 287, a support arm 286, and a hook 285. The base 287 extends outward from the handle base 101. One end of the support arm 286 is connected to the distal end of the base 287, and the other end is connected to the hook 285. The support arm 286 is generally parallel to the extending direction of the handle base 101 and has a gap between it and the rear side 212 of the handle base 101. The hook 285 is bent inward, so that the inner side of the hook 285 forms a second torsion spring engagement portion 215, which can also contact or separate from the second torsion spring 109. A rocker arm shaft 132 is also provided on the rear side of the handle base. The rocker arm shaft 132 is used to mount the rocker arm 104, so that the rocker arm 104 can rotate around the rocker arm shaft 132. The rocker arm shaft 132 is also provided with a second torsion spring connection part 268 for mounting a second torsion spring 109.
[0054] Figure 3A and Figure 3B yes Figure 1B The two perspective views of the handle body in the handle assembly are shown to illustrate the specific structure of the handle body 102. For example... Figure 3A and Figure 3B As shown, the handle body 102 includes a handle 301 and a transmission part 303 extending from the back of the handle 301, wherein the transmission part 303 can pass through the hollow portion 219 in the bottom 232 of the cavity on the handle seat 101 (see Figure 2A and Figure 2BThe transmission part 303 extends from the front side 211 of the handle base 101 to its rear side 212. Therefore, when the handle body 102 is installed on the handle base 101, the transmission part 303 is located at the rear side 212 of the handle base 101. The handle 301 includes an operating end 311 and a connecting end 312, with the transmission part 303 located between the operating end 311 and the connecting end 312, and close to the connecting end 312. The connecting end 312 has a handle body shaft mounting hole 321 for mounting the handle body shaft 901. The handle 301 can rotate around the handle body shaft 901 for unlocking and opening doors. The transmission part 303 is positioned close to the mounting hole 321 on the connecting end 312. One end of the transmission part 303 is connected to the handle 301, and the other end forms a free end. The transmission part 303 also has a top 331 and a bottom 332 disposed opposite to each other. The bottom 332 of the transmission unit 303 has a slope 323, which gradually slopes towards the handle 301 in the direction from the operating end 311 to the connecting end 312. The slope 323 is used to cooperate with the slider 103, so that the linear motion of the slider 103 is effectively converted into the rotational motion of the handle body 102. The transmission unit 303 also includes a protrusion 329 provided at the free end, which is provided on the side of the free end facing the operating end 311 of the handle 301, for cooperating with the rocker arm 104. The handle body 102 also includes a receiving groove 307 for mounting the second torsion spring 109. The receiving groove 307 is also provided on the back of the handle 301 and connected to the transmission unit 303. The receiving groove 307 receives the second torsion spring 109 and allows one end of the second torsion spring 109 to move within the receiving groove 307. The receiving groove 307 is provided on the side of the transmission unit 303 facing the connecting end 312 of the handle. In some embodiments, the receiving groove 307 may be configured to have a certain depth so that one end of the second torsion spring 109 can move within the space defined by the receiving groove 307.
[0055] Figure 4A yes Figure 1B The diagram shows a perspective view of the rocker arm 104 in the handle assembly. Figure 4B yes Figure 4A A three-dimensional view of the rocker arm from another angle. Figure 4A and Figure 4B The structure of rocker arm 104 is shown. (As previously described...) Figure 1A-1C The rocker arm 104 is connected to the back of the handle base 101 via a rocker arm shaft 132. For example... Figure 4A and Figure 4BAs shown, the rocker arm 104 has a front side 406 facing the handle seat 101 and a rear side 408 opposite to the front side 408. The rocker arm also has a left side 421 and a right side 423 opposite to each other, which connect the front side 406 and the rear side 408 respectively. The rocker arm 104 has a rocker arm shaft mounting hole 425 that passes through the front side 406 and the rear side 408 of the rocker arm 104 for mounting the rocker arm shaft 132. The right side of the rocker arm 104 has an actuating part 403, which includes an arc-shaped groove 407. The groove 407 is used to engage with the protrusion 329 on the handle body 102 (see...). Figure 3B The protrusion 329 is slidable in the groove 407. The groove 407 extends from the front side 406 to the rear side 408 of the rocker arm 104, and thus has a first end 471 near the rear side 408 of the rocker arm 104 and a second end 472 near the front side 406 of the rocker arm 104. The upper end of the rocker arm 104 is provided with a locking wire mounting part 429 for mounting the locking wire 140. The distance from the locking wire mounting part 429 to the rocker arm shaft mounting hole 425 is greater than the distance from the groove 407 to the rocker arm shaft mounting hole 425. The locking wire mounting part 429 has a sliding groove 450 with a front end 451 and a rear end 452, in which the locking wire can slide. The rocker arm 104 is also provided with a hole 461 for connecting the first elastic device 108.
[0056] Figure 5 yes Figure 1B A perspective view of the slider 103 in the handle assembly shown. Figure 5 As shown, the upper end of the slider 103 is provided with a contact portion 507 for contacting the transmission portion 303 of the handle body 102. The contact portion 507 contacts the inclined surface 323 on the transmission portion 303 of the handle body 102 (see...). Figure 3A In conjunction with the handle body 102, the handle body 102 is rotated around the handle body axis 901. The side of the slider 103 is provided with a motor connection part 509 for connecting with the motor 105, so that the motor 105 can drive the slider 103 to move.
[0057] Figure 6 yes Figure 1B A perspective view of the first torsion spring 108 in the handle assembly shown. Figure 6As shown, the first torsion spring 108 has a rocker arm connecting end 601 and a handle seat connecting end 602. The rocker arm connecting end 601 is used to connect with the rocker arm 104, and the handle seat connecting end 602 is used to connect with the handle seat 101, so that the first torsion spring 108 provides a reset deflection force between the rocker arm 104 and the handle seat 101. The rocker arm connecting end 601 has a bent portion 615, which is used to insert into the hole 461 on the rocker arm 104, so that the bent portion 615 can fit on the hole 461 of the rocker arm 104, making it difficult for the first torsion spring 108 to fall off the rocker arm 104. The handle seat connecting end 602 has an insertion portion 625 bent toward the handle seat 101, which can be inserted into the mounting hole 182 on the rear side of the handle seat 101.
[0058] Figure 7 yes Figure 1B A perspective view of the second torsion spring 109 in the handle assembly shown. Figure 7 As shown, the second torsion spring 109 includes a body 710, a first arm 701, and a second arm 702, which extend from the body 710. The second arm 702 is used to connect with the handle seat 101. The first arm 701 is used to connect with the handle body 102, with its proximal end 713 abutting against the limiting protrusion 201 and its distal end 714 entering the receiving groove 307 of the handle body 102. When the proximal end 713 of the first arm 701 moves away from the limiting protrusion 201, the distal end 714 of the first arm 701 abuts against the bottom of the receiving groove 307 of the handle body 102, thereby compressing the second torsion spring 109 to provide elastic force between the handle body 102 and the handle seat 101. The force on the handle body 102 can be transmitted to the rocker arm 104. The direction of the second deflection force transmitted by the second torsion spring 109 to the rocker arm 104 through the handle body 102 is opposite to the direction of the deflection force transmitted by the first torsion spring 108 to the rocker arm 104.
[0059] Figure 8 This is a perspective view of motor 105. Motor 105 includes motor drive rod 801, which is connected to slider 103 and can move to drive slider 103 to move.
[0060] Figures 9A-9C These are front perspective views of the handle 102 in the initial position, the first open position, and the second open position during the door lock opening process.
[0061] The process of the handle assembly 100 opening the door lock includes the process of opening the door lock through the handle body 102 and the process of resetting the handle body 102. The process of opening the door lock through the handle body 102 includes a first opening stage and a second opening stage, while the process of resetting the handle body 102 includes a first reset stage and a second reset stage. In the first opening stage, the operator presses the trigger area (not shown in the figure) on the handle body 102, activating the motor 105. The motor 105 causes the handle body 102 to move from its initial position (…). Figure 9A Change to the first open position ( Figure 9B In the second opening phase, the operator rotates the handle 301 outward to move the handle body 102 from the first open position. Figure 9B Change to the second open position ( Figure 9C During the first reset phase, the operator releases handle 301, moving handle 102 from the second open position. Figure 9C Return to the first open position ( Figure 9B In the second reset phase, the operator presses the trigger area on the handle body 102, causing the handle body 102 to move from the first open position. Figure 9B Return to the initial position. Figure 9A ).
[0062] Figure 10A and Figure 10B Is the handle assembly in Figure 9A The image shown is a rear view of the handle body in its initial position. Figure 10C and 10D These are rear perspective views of the handle assembly 100 when the handle body is in the first open position during the door lock opening process. Figure 10E and 10F This is a three-dimensional view of the rear side when the handle is in the second open position, where... Figure 10A , 10C The handle base 101 is retained in the 10E. Figure 10B , 10D In 10F, the handle base 101 is omitted to more clearly show the mating relationship between the components.
[0063] Figure 9A and Figure 10A , Figure 10B The initial position of the handle body 102 is shown, in which the door lock is not opened. Figure 9A As shown, when viewed from the front of the handle assembly 100, the outer surface of the handle body 102 is slightly higher than the entry edge 230 of the handle seat 101, so that when the handle assembly 100 is installed on the door, the outer surface of the handle body 102 is roughly flush with the outer sheet metal of the door, making the handle body 102 appear to be hidden in the door.
[0064] like Figure 10A and Figure 10B As shown, viewed from the rear of the handle assembly 100, the slider 103 is connected to the motor 105 via its motor connection portion 509. The contact portion 507 of the slider 103 abuts against the inclined surface 323 of the transmission portion 303 of the handle body 102, or the contact portion 507 is close to the inclined surface 323 of the transmission portion 303 of the handle body 102 and has a small distance between it and the inclined surface 323. At this time, the slider 103 is in the initial slider position.
[0065] The rocker arm connecting end 601 of the first torsion spring 108 is connected to the rocker arm 104, and the handle seat connecting end 602 of the first torsion spring 108 is connected to the handle seat 101. The first torsion spring 108 is in a compressed state, so that the rocker arm connecting end 601 can apply a first deflection force along the first horizontal direction M1 to the rocker arm 104.
[0066] The distal end of the first arm 701 of the second torsion spring 109 abuts against the handle body 102, and the second arm 702 abuts against the rocker arm shaft 132 on the handle seat 101, with the proximal end 713 of the first arm 701 a certain distance away from the limiting protrusion 201. The second torsion spring 109 is in a compressed state, thereby applying a second deflection force along the second horizontal direction M2 to the handle body 102, wherein the second deflection force is less than the first deflection force. At this time, the protrusion 329 of the handle body 102 abuts against the first end 471 of the groove 407 of the rocker arm 104. One end of the locking wire 140 is located at the front end 451 of the groove 450 of the locking wire mounting part 429.
[0067] Figure 9B , Figure 10C and Figure 10D The first open position of the handle body 102 is shown, in which the door lock is not opened. Figure 9B As shown, viewed from the front of the handle assembly 100, it is similar to... Figure 9A Compared to the initial position of the handle body 102, the handle body 102 has rotated a certain angle around the handle body axis 901 along the first rotation direction R1. The operating end 311 of the handle 301 has left the handle seat 101, forming an operating space 908 between the handle 301 and the handle seat 101. The operating space 908 facilitates the operator's grip on the handle 301 for subsequent second opening stage operations.
[0068] As the handle body 102 rotates along the first rotation direction R1, the transmission part 303 on the back of the handle 301 gradually moves toward the rocker arm 104. Specifically, as Figure 10C and Figure 10D As shown, viewed from the rear of the handle assembly 100, it is similar to... Figure 10A and 10BCompared to the initial position of the handle body 102, the slider 103, driven by the motor 105, moves the transmission part 303 of the handle body 102 a certain distance along the second horizontal direction M2, thereby reaching the slider working position. The protrusion 329 on the transmission part 303 of the handle body 102 moves a certain distance from the first end 471 of the arcuate groove 407 of the rocker arm 104 toward the second end 472. The rocker arm 104 is pushed by the handle body 102 to rotate a certain angle along the third rotation direction R3. The proximal end 713 of the first arm 701 of the second torsion spring 109 contacts the second torsion spring mating part 215 of the limiting protrusion 201. One end of the locking wire 140 is located at the rear end 452 of the groove 450 of the locking wire mounting part 429.
[0069] Figure 9C , Figure 10E and Figure 10F The second open position of the handle body 102 is shown, in which the door lock is unlocked. Figure 9C As shown, viewed from the front of the handle assembly 100, it is similar to... Figure 9B Compared to the first open position of the handle body 102 shown, the handle body 102 continues to rotate around the handle body axis 901 along the first rotation direction R1 by a certain angle, and the operating end 311 of the handle 301 reaches the farthest position relative to the handle seat 101.
[0070] like Figure 10E and Figure 10F As shown, viewed from the rear of the handle assembly 100, the slider 103 and the motor 105 maintain the same position. Figure 10C The slider is shown in its working position. As the handle body 102 continues to rotate around the handle body axis 901 in the first rotation direction R1, the handle body 102 drives the rocker arm 104 to rotate in the third rotation direction R3 to reach its farthest position, and the protrusion 329 of the handle body 102 reaches the second end 472 of the groove 407 of the rocker arm 104 (see...). Figure 4A At this time, the proximal end 713 of the first arm 701 of the second torsion spring 109 abuts against the limiting protrusion 201 on the second torsion spring mating part 215; while the distal end of the first arm 701 leaves the bottom of the receiving groove 307 of the handle body 102, thereby forming a certain distance between it and the handle body 102.
[0071] In the first opening stage, that is, from the handle 102... Figure 9A The initial position of the handle body 102 shown is reached Figure 9BDuring the first open position of the handle body 102, the motor 105 needs to be activated. The motor 105 drives the handle body 102 to rotate outward (i.e., along the first rotation direction R1) by a certain angle. More specifically, when the operator needs to unlock the door, the operator touches the trigger area on the handle body 102. The motor 105 receives the corresponding signal and starts. The drive rod 801 of the motor 105 moves linearly along the second horizontal direction M2, thereby pushing the slider 103 to move towards the rocker arm 104 along the second horizontal direction M2 in the slider channel. During the movement of the slider 103 along the second horizontal direction M2, the contact part 507 of the slider 103 contacts the inclined surface 323 of the transmission part 303 of the handle body 102. Since the handle body 102 is fixed to the handle base 101 by the handle body shaft 901, the linear motion of the slider 103 can be converted into the rotational motion of the handle body 102. Specifically, after the contact portion 507 of the slider 103 contacts the inclined surface 323 of the transmission portion 303 of the handle body 102, the slider 103 moves under the drive of the motor 105, pushing the inclined surface 323 of the transmission portion 303 of the handle body 102, causing the handle body 102 to rotate around the handle body axis 901 until the handle body 102 rotates to the first open position. At this time, the motor 105 stops, for example, upon receiving a signal from a sensor (not shown), and the slider 103 no longer moves, reaching the slider working position. During the process of the slider 103 being driven by the motor 105 to push the handle body 102 to rotate toward the first open position, the rotation of the handle body 102 pushes the rocker arm 104 to rotate along the third rotation direction R3. During this process, the motor 105 sequentially applies a thrust F3 along the second horizontal direction M2 to the rocker arm 104 via the slider 103 and the handle body 102. The second torsion spring 109 applies a second deflection force F2 along the second horizontal direction M2 to the rocker arm 104 via the handle body 102. F2 and F3 together overcome the first deflection force F1 along the first horizontal direction M1 applied to the rocker arm 104 by the first torsion spring 108, causing the rocker arm 104 to rotate along the third rotation direction R3. Due to the rotation of the rocker arm 104, one end of the locking wire 140 changes from the front end 451 of the groove 450 in the locking wire mounting part 429 to the rear end 452 of the groove 450 in the locking wire mounting part 429. During this process, the locking wire 140 remains stationary. Because of the second deflection force F2 contributed by the second torsion spring 109, the motor 105 only needs to apply a small thrust F3 to the rocker arm 104 to overcome the first deflection force F1 of the first torsion spring 108 and drive the rocker arm 104 to rotate. Compared with not having the second torsion spring 109, the handle assembly in this application can reduce the wear and tear on the motor 105 and extend the service life of the motor 105.
[0072] In the second opening stage, that is, from the handle 102... Figure 9B The handle body is shown in the first open position. Figure 9C During the process of the handle body 102 reaching the second open position, the operator needs to manually rotate the handle body 102 further outward. Specifically, when the handle body 102 reaches the first open position, an operating space 908 is formed between the handle body 102 and the handle seat 101. The operator can insert their hand into the operating space 908 and grasp the operating end 311 of the handle 301. Subsequently, the operator applies force to the handle 301 to rotate the handle body 102 along the first rotation direction R1 until the second open position of the handle body 102 is reached. During the process of the handle body 102 continuing to rotate along the first rotation direction R1, the protrusion 329 of the transmission part 303 of the handle body 102 also rotates along the first rotation direction R1. The protrusion 329 slides in the arc-shaped groove 407 of the rocker arm 104 to the second end 472 (see Figure 4A As the protrusion 329 slides toward the second end 472 of the groove 407, the protrusion 329 applies force to the actuating part 403 of the rocker arm 104, thereby overcoming the first deflection force applied to the rocker arm 104 by the first torsion spring 108, causing the actuating part 403 of the rocker arm 104 to move away from the handle body axis 901, thereby driving the rocker arm 104 to rotate in the third rotation direction R3. During this process, the proximal end 713 of the first arm 701 of the second torsion spring 109 abuts against the limiting protrusion 201, and the distal end of the first arm 701 moves away from the handle body 102, so the second torsion spring 109 can no longer apply a deflection force to the rocker arm 104 through the handle body 102. That is to say, in the second opening stage, the second torsion spring 109 separates from the rotational movement of the handle body 101 and no longer participates in the rotational movement of the handle body 101.
[0073] In the second opening phase, one end of the locking wire 104 is located in the rear end 452 of the slide groove 450 and abuts against the side wall of the rear end 452 of the slide groove 450. Thus, the rotation of the rocker arm 104 will drive the locking wire 104 to move simultaneously to pull the bolt to unlock. In the second open position, the transmission part 303 of the handle body 102 abuts against the rear side of the handle seat 101, so that the handle body 102 cannot continue to rotate.
[0074] As described above, during the process of the operator pulling the handle 102 from the initial position to the first open position, the force that needs to be overcome is the difference between the first deflection force provided by the first torsion spring 108 to the rocker arm 104 and the second deflection force provided by the second torsion spring 109 to the rocker arm 104. During this process, the first torsion spring 108 is compressed to accumulate the first deflection force for resetting. The slider 103 and the motor 105 remain in place. Figure 9B and Figure 10BThe position shown remains unchanged. During the process of the operator pulling the handle 102 from the first open position to the second open position, the force that needs to be overcome is the first deflection force provided by the first torsion spring 108 to the rocker arm 104. In the second opening phase, the force required for the movement of the handle 102 is provided entirely by the operator; the slider 103 and motor 105 do not participate in the movement of the handle 102 and rocker arm 104 during the second opening phase.
[0075] In the first reset phase, the operator releases the handle 301, and the rocker arm 104 is pushed by the first deflection force of the first torsion spring 108, thus rotating along a fourth rotation direction R4, which is opposite to the third rotation direction R3. Simultaneously with the rotation of the rocker arm 104, the actuating part 403 of the rocker arm 104 pushes the transmission part 303 of the handle body 102, causing the handle body 102 to rotate along a second rotation direction R2, which is opposite to the first rotation direction R1, until the handle body 102 returns to the first open position (i.e.,...). Figure 10C (as shown in the diagram). That is, during the process of the handle body 102 returning from the second open position to the first open position, the first torsion spring 108 provides the necessary power for the handle body 102 to reset. As the handle body 102 returns to the first open position, the transmission part 303 of the handle body 102 contacts the slider 103. However, the slider 103 is held in the slider working position by the power of the motor 105, thus preventing the handle body 102 from continuing to rotate. At this time, the first deflection force provided by the first torsion spring 108 to the rocker arm 104 is insufficient to overcome the force provided by the motor 105 to the rocker arm 104 through the slider 103 and the handle body 102, thereby holding the handle body 102 in the first open position.
[0076] In the second reset phase, the operator presses the trigger area, and the motor 105 receives the signal to retract the drive lever 801, causing the slider 103 to move along the first horizontal direction M1, so that the slider 103 returns to the initial position of the slider (i.e., Figure 10D (as shown in the image). Simultaneously, the first deflection force provided by the first torsion spring 108 to the rocker arm 104 is greater than the second deflection force provided by the second torsion spring 109 to the rocker arm 104, thereby causing the rocker arm 104 to rotate along the fourth rotation direction R4, thereby driving the handle body 102 to rotate along the second rotation direction R2 back to the initial position of the handle body (i.e.,...). Figure 9A (As shown in the figure), the handle 102 completes the reset process.
[0077] In the second opening phase of the handle body 102, which is the process of unlocking the car door, the return force provided by the elastic device to the handle body 102 is typically required to be within a certain range (e.g., approximately 10-25N when the rocker arm 104 is not connected to the latch, and 35-65N when the rocker arm 104 is connected to the latch) to ensure operator comfort and reliability. However, in the first opening phase of the handle body 102, the handle body is changed from a position flush with the car door to an easily operable position. During this process, the handle body 102 does not require excessive return force; otherwise, for handle assemblies containing a motor, the motor would have to overcome a large return force, reducing its durability. For handle assemblies without a motor, the operator would also need to apply significant force during this phase, making operation inconvenient. In the above embodiments of this application, by providing an additional second elastic device, only a portion of the force provided by the first elastic device can be offset by the second elastic device during the first opening phase of the handle body 102, reducing the total force that needs to be overcome during the first opening phase of the handle body 102. This reduces the load on the motor and helps extend its service life. Furthermore, since the elastic force of the reset elastic device that needs to be overcome in the first opening stage of the handle body 102 is small, the first opening stage can be performed manually by the operator (i.e., manually rotating the handle body 102). Therefore, even if the motor is not working or is not installed, the operator can conveniently perform the first opening stage of the handle body 102 manually.
[0078] In some embodiments, the ratio of the elastic force provided by the first torsion spring 108 and the second torsion spring 109 to the operating end 311 is approximately 1.5-3:1. In some embodiments, the ratio of the elastic force provided by the first torsion spring 108 and the second torsion spring 109 to the operating end 311 is 5:2.
[0079] In some embodiments, the second torsion spring 109 may also be disposed between the rocker arm 104 and the handle seat 101, as long as it can provide a force to the rocker arm 104 in the opposite direction to the deflection force provided by the first torsion spring 108.
[0080] In some embodiments, the extension direction of the handle body shaft 901, the extension direction of the rocker arm shaft 132, and the movement direction of the slider 103 are perpendicular to each other. In some embodiments, the actuating portion 403 of the rocker arm 104 is closer to the rocker arm shaft 132 than the locking wire mounting portion 429 of the rocker arm 104. In some embodiments, the transmission portion 303 of the handle body 102 is closer to the handle body shaft 901 than the operating end 311 of the handle 301. As a result, the handle assembly can be designed to be more compact.
[0081] Although only some features of this application have been illustrated and described herein, many modifications and variations will be apparent to those skilled in the art. Therefore, it should be understood that the appended claims are intended to cover all such modifications and variations that fall within the essential spirit and scope of the invention.
