[0079] The following is a detailed description of the embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0080] like Figure 1 and Figure 2 As shown, the embodiment of the present application discloses a vehicle, comprising a vehicle body, a door, and a handle 10. The vehicle body and the door are fixedly connected via a lock body. The handle 10 is fixed to the door and is used to drive the door to rotate relative to the vehicle body and to unlock the locked position of the lock body. Furthermore, a rocker arm 100 is provided in the handle 10. The rocker arm 100 is connected to the lock body via a cable, and the rocker arm 100 operates the unlocking operation of the lock body via the cable (the specific principle and structure are prior art and are not described in detail here).

[0081] The handle 10 further includes a base 200 and a handle frame 300. The rocker arm 100 is fixed to the base 200 via a first rotating shaft 700 and is connected to a portion of the handle frame 300.

[0082] Specific, combined Figure 1-Figure 3As shown, the base 200 is fixedly connected to the door body, and the handle frame 300 can be rotatably connected to one end of the base 200. The base 200 includes a positioning channel 210. The handle frame 300 includes a holding arm 310 and an extension arm 320. The extension arm 320 is connected to the holding arm 310, and the end of the holding arm 310 away from the extension arm 320 is rotatably connected to the base 200. At the same time, the extension arm 320 is located in the positioning channel 210, and the extension arm 320 passes through the positioning channel 210. The end of the extension arm 320 away from the holding arm 310 is connected to the rocker arm 100 for unlocking the lock body. When the holding arm 310 rotates relative to the base 200, the extension arm 320 is used to slide in the positioning channel 210 along the first direction X, and drive the rocker arm 100 to rotate, thereby driving the pull wire to unlock the lock body (automatic Figure 1 The displayed status switches to Figure 2 In other words, when the extension arm 320 is slidably disposed on the base 200, the rocker arm 100 is used to drive the lock body to unlock.

[0083] It should be noted that the first direction X is parallel to the extending direction of the extension arm 320 , and the second direction Y is perpendicular to the first direction X.

[0084] The inventors have found that when the vehicle is hit from the side, the handle frame 300 will rotate relative to the base 200 (from Figure 1 The displayed status switches to Figure 2 The extending arm 320 will extend and slide in the positioning channel 210, thereby driving the rocker arm 100 to rotate and unlock, causing a mis-locking situation.

[0085] In order to improve the above problems, Figure 4 As shown, the inventors have added a stopper 400 to the handle 10. The stopper 400 is fixedly connected to the extension arm 320 along the first direction X. Along the first direction X, the base 200 includes an outer side 201 and an inner side 202 that are oppositely disposed. The side of the base 200 that is closer to the vehicle interior is referred to as the inner side 202, and the side of the base 200 that is farther from the vehicle interior is referred to as the outer side 201.

[0086] Combine Figure 4-Figure 8 As shown, the limiting member 400 includes a limiting state 401 and a free state 402 .

[0087] like Figure 4 and Figure 7 As shown, when the limiting member 400 is in the free state 402 , the limiting member 400 is located in the positioning channel 210 and is configured to slide in the positioning channel 210 along the first direction X. In this state, the limiting member 400 moves along the first direction X with the extension arm 320 without affecting the movement of the extension arm 320 , that is, without affecting the movement of the rocker arm 100 .

[0088] like Figure 4 and Figure 8 As shown, when the limiting member 400 is in the limiting state 401, the limiting member 400 abuts against the wall of the positioning channel 210 away from the outer side 201 and is used to securely connect the base 200 and the handle frame 300 along the first direction X. In this state, the limiting member 400 can prevent the extension arm 320 from moving in the positioning channel 210, thereby preventing the rocker arm 100 from moving, thereby preventing accidental unlocking of the lock body.

[0089] During use, when the handle 10 is no longer needed to unlock and open the door, the limiting member 400 needs to be switched to the limiting state 401 to actively limit the movement of the rocker arm 100. This arrangement can reduce or prevent relative movement of the handle frame 300 in the handle 10 relative to the base 200 in the event of a side impact, thereby preventing accidental unlocking of the lock body and ensuring that the door and vehicle body remain effectively locked.

[0090] In this embodiment, the base 200 is provided with two parallel positioning plates 220 extending along the first direction X. The two positioning plates 220 are spaced apart along the second direction Y and form a positioning channel 210. In the above arrangement, the original structure of the base 200 is retained to achieve cooperation with the limiting member 400.

[0091] like Figure 3 and Figure 4 As shown, the handle 10 further includes a pulling assembly 500. A portion of the pulling assembly 500 is located within the extension arm 320 and is configured to move relative to the extension arm 320 in a first direction X. The limiting member 400 is rotatably coupled to the pulling assembly 500. When the structure of the pulling assembly 500 located within the extension arm 320 moves relative to the extension arm 320 in the first direction X, the limiting member 400 rotates and switches between a restricted state 401 and a free state 402.

[0092] Through the above arrangement, the user can control the position of the limiting member 400 by operating the movement of the pulling component 500 .

[0093] Specifically, such as Figure 3-10 As shown, in this embodiment, the pulling assembly 500 includes a pulling rod 510 and a swing arm 520 .

[0094] One end of the pull rod 510 is located in the extension arm 320 and is rotatably connected to the limit member 400. The other end extends out of the extension arm 320 and is connected to the swing arm 520. The swing arm 520 is used to drive the pull rod 510 to move in the first direction X and to drive the limit member 400 to switch from the restricted state 401 to the free state 402. In this arrangement, the movement of the pull rod 510 is controlled by swinging the swing arm 520, thereby controlling the rotation of the limit member 400.

[0095] In this embodiment, the housing 330 includes a front cover 311 and a rear cover 312, which together form a housing space 313. Part of the structure of the swing arm 520 is located within the housing space 313 in the housing 330. One end of the swing arm 520 is rotatably connected to the housing 330 via a second rotating shaft 800, and the other end is connected to the pull rod 510. In other words, the swing arm 520 can rotate relative to the housing 330, driving the pull rod 510 to move, thereby changing the state of the stopper 400. In this arrangement, the movement of the pull rod 510 can be controlled by driving the swing arm 520 to rotate, providing convenient operation. When the force application point is away from the second rotating shaft 800, the swing arm 520 and the pull rod 510 can be easily driven to move. In this embodiment, the swing arm 520 drives the pull rod 510 to move by rotating relative to the housing 330, thereby changing the state of the stopper 400. Of course, in other embodiments, the swing arm 520 may drive the pull rod 510 to move by moving along the first direction X relative to the housing 330 , thereby changing the state of the limiting member 400 .

[0096] like Figure 3 、 Figure 4 、 Figures 9-11 As shown, refer to Figure 7 and Figure 8 The handle 10 further includes a reset member 600, one end of which is fixed to the handle frame 300 and the other end of which is connected and fixed to the pulling assembly 500. The reset member 600 is used to drive the pulling assembly 500 to exert motion in the first direction X and to drive the limiting member 400 to switch from the free state 402 to the limited state 401.

[0097] In this embodiment, the reset member 600 is a spring. The reset member 600 is located on the side of the pulling assembly 500 away from the base 200. In other words, one end of the limiting member 400 abuts against the end of the pulling assembly 500 away from the base 200, and the other end abuts against the front housing 311. When an external force is applied to the swing arm 520 in a direction from the inner side 202 toward the outer side 201, the swing arm 520 rotates forward, thereby moving the pull rod 510 and switching the limiting member 400 from the restricted state 401 to the free state 402. During this process, the reset member 600 is compressed. When the external force on the swing arm 520 is removed, the reset member 600, under the action of its elastic potential energy, applies a force from the outer side 201 toward the inner side 202 to the swing arm 520, causing the swing arm 520 to rotate in the opposite direction, thereby driving the pull rod 510 in the opposite direction and switching the limiting member 400 from the free state 402 to the restricted state 401. Specifically, the reset member 600 may be fixed to the end of the pull rod 510 away from the limiting member 400. Alternatively, the reset button may also be fixed to the swing arm 520.

[0098] Of course, in other embodiments, the reset member 600 may also be located on the side of the pulling assembly 500 close to the base 200 . In other words, one end of the limiting member 400 abuts against the end of the pulling assembly 500 close to the base 200 , and the other end abuts against the rear end cover 312 .

[0099] It should be noted that the movements of the swing arm 520 and the pull rod 510 referred to here are the movements of the two relative to the handle frame 300.

[0100] like Figure 5 and Figure 6 As shown, at least portions of the base 200 and the handle frame 300 are spaced apart along a first direction X, forming a gripping area 301. A hollowed-out area 302 is provided on the handle frame 300, through which at least portions of the swing arm 520 are exposed to the gripping area 301. Furthermore, the swing arm 520 located in the gripping area 301 is movable along the first direction X. In this embodiment, the hollowed-out area 302 is provided on the rear end cover 312. In this arrangement, portions of the swing arm 520 are exposed through the hollowed-out area 302. When a user needs to unlock the handle 10, they first need to reach into the gripping area 301 and apply a force directed from the inner side 202 toward the outer side 201 to the gripping arm 310 located in the hollowed-out area 302, causing the swing arm 520 to rotate, thereby driving the pull rod 510 to move, thereby driving the limiting member 400 to switch from the restricted state 401 to the free state 402. When the user does not apply force to the holding arm 310, under the action of the reset member 600, the limit member 400 always remains in the limit state 401, thereby ensuring that the pull rod 510 cannot move along the first direction X, and further making the extension arm 320 unable to move in this state and drive the rocker arm 100 to perform an erroneous unlocking action.

[0101] In order to ensure effective fixation of the pull rod 510 and the swing arm 520, the inventors have made the following design:

[0102] like Figure 4 、 Figures 9-11 As shown, a positioning block 511 is provided at one end of the pull rod 510 away from the stopper 400. The positioning block 511 includes an abutment surface 512 facing the stopper 400. The abutment surface 512 abuts against the swing arm 520, which is used to apply a force from the inner side 202 to the outer side 201 to the pull rod 510. In this embodiment, the reset member 600 applies a force from the outer side 201 to the inner side 202 to the positioning block 511. Through the abutment relationship between the pull rod 510 and the swing arm 520, the force is transmitted to the swing arm 520, causing the swing arm 520 to rotate in the opposite direction.

[0103] The swing arm 520 includes a contact surface 521, which is used to abut against the abutting surface 512, and the shape of the contact surface 521 is compatible with the shape of the abutting surface 512. At least part of the structure of the abutting surface 512 is raised in the direction from the positioning block 511 to the limit member 400, and accordingly, a corresponding depression is formed on the contact surface 521. Alternatively, in other embodiments, at least part of the structure of the abutting surface 512 may be recessed in the direction from the limit member 400 to the positioning block 511, and accordingly, a corresponding depression is formed on the contact surface 521. Through the above arrangement, the pull rod 510 can be prevented from rotating during the movement, thereby affecting the drive of the pull rod 510.

[0104] In this embodiment, combined with Figure 3-Figure 8 As shown, refer to Figure 9 and Figure 10 As shown. A movement space 321 is provided inside the extension arm 320, and the pull rod 510 is located in the movement space 321. A penetrating limiting hole 322 is provided on the side wall of the extension arm 320, and the limiting hole 322 is connected to the movement space 321. The limiting member 400 includes an annular portion 410 and a raised portion 420. The annular portion 410 is located in the movement space 321 and is sleeved on the pull rod 510. The pull rod 510 and the annular portion 410 are threadedly connected and can achieve relative rotation. The raised portion 420 extends out of the movement space 321 from the limiting hole 322 and is used to abut against the wall of the positioning channel 210 away from the outer side 201. Through the cooperation of the limiting hole 322 and the raised portion 420, the movement of the raised portion 420 along the first direction X can be limited, that is, the movement of the limiting member 400 along the first direction X can be limited. With the above arrangement, when the swing arm 520 and the reset member 600 push the pull rod 510 to move along the first direction X, the limit member 400 can rotate relative to the pull rod 510 to switch between the free state 402 and the limit state 401 .

[0105] Furthermore, the inventors discovered that when the length of the raised portion 420 is too small, and when the limiting member 400 is in the limiting state 401, the limiting member 400 and the positioning channel 210 are not conducive to maintaining a stable abutment relationship between the limiting member 400 and the wall surface of the positioning channel 210. When the length of the raised portion 420 is too large, it is not conducive to ensuring the stability of the overall structure of the limiting member 400. In order to balance the above problems, the inventors conducted a large number of experiments and found that when the length of the raised portion 420 is greater than or equal to 3 mm and less than or equal to 10 mm, the above problems can be effectively balanced, ensuring the structural stability of the limiting member 400 while ensuring that when the limiting member 400 is in the limiting state 401, the limiting member 400 and the positioning channel 210 can maintain a relatively stable connection relationship. In this embodiment, the length of the raised portion 420 is 7 mm. At the same time, the inventor found that when the limit member 400 is in the limit state 401, the contact area between the limit member 400 and the wall of the positioning channel 210 away from the outer side 201 needs to be greater than or equal to 3 square meters to ensure that the two have a sufficiently large contact surface 521 area, thereby ensuring that the pull rod 510 cannot move along the first direction X, and thus the extension arm 320 cannot move in this state and drive the rocker arm 100 to perform an erroneous unlocking action.

[0106] The above description is merely a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with this profession can make slight changes or modifications to equivalent embodiments with equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present application. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
