Description

Unlocking device, door assembly and car

[0001] This application claims priority to Chinese patent applications filed on July 11, 2024, with application number 202410933452.9 entitled "Unlocking Device, Door Assembly and Automobile" and application number 202421646945.6 entitled "Unlocking Device, Door Assembly and Automobile", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of vehicle door assembly technology, and more particularly to an unlocking device, a vehicle door assembly, and an automobile. Background Technology

[0003] An unlocking device is a device used to unlock a lock. Currently, many devices are equipped with unlocking devices, but the inventors realized that most existing unlocking devices operate by rotating around an axis, which occupies a lot of space and has limited operation. For example, the unlocking device on a current car door assembly includes an unlocking mechanism and an inward-opening handle. The inward-opening handle rotates around an axis to control the unlocking mechanism to unlock the lock. This results in a large amount of exposed structure on the inward-opening handle, which limits its operation. Summary of the Invention

[0004] This application provides an unlocking device, a door assembly, and an automobile to solve the problems that most existing unlocking devices operate by rotating around an axis, which occupies a large space and has a relatively limited operation.

[0005] An unlocking device includes a support base, a sliding mechanism, an unlocking mechanism, and a handle;

[0006] The sliding mechanism and the unlocking mechanism are mounted on the support base;

[0007] The handle is slidably connected to the sliding mechanism and connected to the unlocking mechanism, and is used to control the unlocking mechanism to unlock the lock body when the handle slides in the first direction.

[0008] A vehicle door assembly includes a vehicle door, a lock body, and the aforementioned unlocking device;

[0009] Both the unlocking device and the lock body are installed on the vehicle door, and the unlocking device is used to unlock the lock body.

[0010] An automobile includes the aforementioned door assembly.

[0011] The unlocking device provided in this application embodiment is a device for unlocking a lock body and can be applied to many devices, such as a car door assembly, to unlock the lock body of the car door. The unlocking device specifically includes a support base, a sliding mechanism, an unlocking mechanism, and a handle. During installation, the support base serves as a reference component to support other mechanisms. The sliding mechanism and the unlocking mechanism are mounted on the support base, and the handle is slidably connected to the sliding mechanism, allowing the handle to move along a first direction (i.e., the sliding direction). The handle is also connected to the unlocking mechanism; when the user operates the handle to slide it along the first direction, the unlocking mechanism connected to it can be controlled to unlock the lock body. Compared to the traditional rotational operation method, the sliding operation method of the unlocking device in this example is more compact, occupies less space, has a novel appearance, and offers greater design freedom. It is easier to operate and more novel, increasing the product's attractiveness and uniqueness. The space required for the handle to slide is smaller, reducing the structural design space requirements and limitations of the handle. Attached Figure Description

[0022] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] This application provides an unlocking device. Referring to FIG1, the unlocking device includes a support base 1, a sliding mechanism 2, an unlocking mechanism 3, and a handle 4. The sliding mechanism 2 and the unlocking mechanism 3 are disposed on the support base 1. The handle 4 is slidably connected to the sliding mechanism 2 and connected to the unlocking mechanism 3, and is used to control the unlocking mechanism 3 to unlock the lock body when the handle 4 slides in a first direction.

[0024] The first direction is the sliding direction of the handle 4. When the unlocking device is applied to the door assembly, the first direction is the front-to-back direction of the vehicle.

[0025] As an example, this unlocking device is used to unlock a lock body and can be applied to many devices, such as car door assemblies, to unlock the lock body of the car door. Specifically, the unlocking device includes a support base 1, a sliding mechanism 2, an unlocking mechanism 3, and a handle 4. During installation, the support base 1 serves as a reference component to support the other mechanisms. The sliding mechanism 2 and the unlocking mechanism 3 are mounted on the support base 1. The first end of the unlocking mechanism 3 is connected to the handle 4, and the second end is connected to the lock body. The handle 4 is slidably connected to the sliding mechanism 2, allowing the handle 4 to move along a first direction (i.e., the sliding direction). The handle 4 is also connected to the unlocking mechanism 3. When the user operates the handle 4 to slide it along the first direction, the unlocking mechanism 3 connected to it can be controlled to unlock the lock body. Compared to the traditional rotational operation method, the sliding operation method of the unlocking device in this example is more compact, occupies less space, has a novel appearance, and allows for greater design freedom. It is easier to operate and more novel, increasing the product's attractiveness and uniqueness. The handle 4 requires less space to slide, reducing the structural design space requirements and limitations of the handle 4.

[0026] For example, the unlocking device is applied to the door assembly. The support base 1 is installed on the decorative panel 8 of the door assembly. The sliding mechanism 2 and the unlocking mechanism 3 are set on the support base 1. The handle 4 is slidably connected to the sliding mechanism 2, so that the handle 4 can move along the first direction (i.e., the sliding direction). The handle 4 is also connected to the unlocking mechanism 3. When the user operates the handle 4 and slides it along the first direction, the unlocking mechanism 3 connected to it can be controlled to unlock the lock body, thereby unlocking the door. Compared with the traditional solution, the unlocking device in this example can reduce the space occupation by the horizontal movement of the handle 4, avoid restricting the seating space of other components or passengers, and improve the space utilization rate. It has a compact structure, occupies little space, has a novel appearance, and has greater freedom of design, increasing the creative space inside the door. It has a more unique shape and aesthetics, which can increase the attractiveness and uniqueness of the product.

[0027] In one embodiment, referring to FIG1, the sliding mechanism 2 includes a guide rod 21 disposed on the support base 1 along a first direction; the handle 4 is provided with a sliding hole, and the guide rod 21 passes through the sliding hole.

[0028] As an example, a first method of sliding the handle 4 is introduced. The sliding mechanism 2 includes a guide rod 21, which is arranged on the support base 1 along a first direction. The handle 4 is provided with a sliding hole, which is arranged along the first direction. The guide rod 21 matches the sliding hole. The handle 4 can be slidably mounted on the guide rod 21 through the sliding hole. In this way, the handle 4 can move along the first direction on the guide rod 21 to control the unlocking mechanism 3 to unlock the lock body.

[0029] In one embodiment, referring to FIG1, the sliding mechanism 2 includes a slide rail disposed on the support base 1 along a first direction; the handle 4 is slidably connected to the slide rail.

[0030] As an example, a second method of sliding the handle 4 is introduced. The sliding mechanism 2 includes a slide rail (not shown in the figure), which is set on the support base 1 along a first direction. The handle 4 itself has a protrusion that matches the slide groove in the slide rail. In this way, the handle 4 can reciprocate within the slide rail along the first direction to control the unlocking mechanism 3 to unlock the lock body. For example, when the unlocking device is applied to a car door assembly, and the first direction is the forward and backward direction of the vehicle, when the user operates the handle 4 to slide forward along the slide rail, the unlocking mechanism 3 can be controlled to unlock the lock body. Conversely, when the user operates the handle 4 to slide backward along the slide rail, the unlocking mechanism 3 can be controlled to reset.

[0031] In one embodiment, referring to FIG1, the sliding mechanism 2 further includes a slider, which is slidably mounted in the slide rail, and the handle 4 is connected to the slider.

[0032] As an example, a third way of sliding the handle 4 is introduced. The sliding mechanism 2 also includes a slider, which is slidably installed in the slide rail. Then the handle 4 is connected to the slider, and the handle 4 can drive the slider to move in the slide rail in the first direction to control the unlocking mechanism 3 to unlock the lock body.

[0033] In one embodiment, referring to FIG1, the handle 4 includes a handle body 41 and a push-pull portion 42 disposed on the side of the handle body 41 away from the support base 1; the handle body 41 is slidably connected to the sliding mechanism 2 and the handle body 41 is connected to the unlocking mechanism 3.

[0034] As an example, the handle 4 includes a handle body 41 and a push-pull portion 42. The handle body 41 is slidably connected to the sliding mechanism 2, and the push-pull portion 42 is located on the side of the handle body 41 away from the support base 1. This configuration allows the user to hold the push-pull portion 42 and push or pull the handle body 41, causing the handle body 41 to slide along the sliding mechanism 2. During the sliding process of the handle body 41, a portion of the unlocking mechanism 3 connected to it will move along a first direction to control the unlocking mechanism 3 to unlock the lock body. For example, on a car door assembly, the handle 4 is an occupant operating structure, allowing the occupant to control the handle 4 to slide along the vehicle's front-to-back direction to unlock the door.

[0035] In one embodiment, referring to Figures 1, 2 and 3, the unlocking mechanism 3 includes a cable 31, a cable ball head 32 and a limiting guide sleeve 33; the cable ball head 32 is fixed to the first end of the cable 31 and connected to the handle 4; the limiting guide sleeve 33 is disposed on the support base 1, the first end of the limiting guide sleeve 33 is fixed to the second end of the cable 31, and the second end of the limiting guide sleeve 33 is connected to the lock body.

[0036] As an example, the unlocking mechanism 3 includes a cable 31, a cable ball head 32, and a limiting guide sleeve 33. During installation, the cable ball head 32 is fixed to the first end of the cable 31 and connected to the handle 4. The limiting guide sleeve 33 is set on the support base 1, and the first end of the limiting guide sleeve 33 is fixed to the second end of the cable 31. The second end of the limiting guide sleeve 33 is used to unlock the lock body. When the handle 4 moves in the first direction (i.e., the sliding direction), it can drive the cable ball head 32 to move, and the cable 31 pulls the limiting guide sleeve 33 to move, so that the limiting guide sleeve 33 unlocks the lock body. Among them, the cable ball head 32 is a metal part, and the rest are injection molded parts.

[0037] In one embodiment, referring to FIG1, the unlocking device further includes a transmission mechanism 5 for connecting the handle 4 and the unlocking mechanism 3.

[0038] As an example, the unlocking device also includes a transmission mechanism 5, which connects the handle 4 and the unlocking mechanism 3. This allows the handle 4 to control the movement of the unlocking mechanism 3 via the transmission mechanism 5, thereby controlling the unlocking mechanism 3 to unlock the lock body.

[0039] In one embodiment, referring to Figures 1 and 4, the transmission mechanism 5 is rotatably mounted on the support base 1. The first end of the transmission mechanism 5 is connected to the handle 4, and the second end of the transmission mechanism 5 is connected to the unlocking mechanism 3. The handle 4 drives the transmission mechanism 5 to rotate, thereby driving the unlocking mechanism 3 to move.

[0040] As an example, during installation, the transmission mechanism 5 is rotatably mounted on the support base 1. The transmission mechanism 5 can rotate around its central axis connected to the support base 1. The first end of the transmission mechanism 5 is connected to the handle 4, and the second end of the transmission mechanism 5 is connected to the unlocking mechanism 3. By sliding the handle 4 along the first direction, the transmission mechanism 5 can be driven to rotate around its central axis connected to the support base 1, thereby driving the unlocking mechanism 3 to move and unlock the lock body. Specifically, when the handle 4 moves along the first direction (i.e., the sliding direction), the transmission mechanism 5 drives the cable ball head 32 to move, and the cable 31 pulls the limiting guide sleeve 33 to move, so that the limiting guide sleeve 33 unlocks the lock body.

[0041] In one embodiment, referring to Figures 3 and 4, the support base 1 is provided with a fixed shaft 9 arranged along the second direction; the transmission mechanism 5 includes a fork 51 and a pull rod 52; the pull rod 52 is fitted on the fixed shaft 9; the first end of the fork 51 is connected to the handle 4, the first end of the pull rod 52 is connected to the second end of the fork 51, and the second end of the pull rod 52 is connected to the unlocking mechanism 3; the handle 4 is used to drive the pull rod 52 to rotate around the fixed shaft 9 in the unlocking direction through the fork 51, so as to drive the unlocking mechanism 3 to unlock the lock body.

[0042] The second direction is the direction perpendicular to the first direction.

[0043] As an example, the support base 1 is provided with a fixed shaft 9 arranged in the second direction, and the transmission mechanism 5 includes a fork 51 and a pull rod 52. During installation, the pull rod 52 is fitted onto the fixed shaft 9, and the pull rod 52 can rotate around the fixed shaft 9. The first end of the fork 51 is connected to the handle 4, the first end of the pull rod 52 is connected to the second end of the fork 51, and the second end of the pull rod 52 is connected to the unlocking mechanism 3. With this arrangement, the fork 51 slides along the slide rail arrangement direction, i.e., the first direction, under the drive of the handle 4. While sliding along the first direction, the fork 51 drives the pull rod 52 to rotate around the fixed shaft 9 in the unlocking direction, so as to drive the unlocking mechanism 3 to move, so that the unlocking mechanism 3 unlocks the lock body.

[0044] In one embodiment, referring to Figures 3 and 5, the fork 51 includes a fork body 511, a first connecting arm 512 extending from one side of the fork body 511 in a direction perpendicular to the fork body 511, and a second connecting arm 513 extending from one end of the first connecting arm 512 in a direction perpendicular to the first connecting arm 512. The second connecting arm 513 has a fork groove 514 in the middle. The fork body 511 is connected to the handle 4, and the first end of the pull rod 52 is installed in the fork groove 514 through the adapter shaft 7.

[0045] As an example, the fork 51 includes a fork body 511, a first connecting arm 512, a second connecting arm 513, and a fork groove 514. During installation, the fork body 511 is connected to the handle 4. The first connecting arm 512 extends from one side of the fork body 511 in a direction perpendicular to the fork body 511. The second connecting arm 513 extends from one end of the first connecting arm 512 in a direction perpendicular to the first connecting arm 512. The fork groove 514 is located in the middle of the second connecting arm 513. The first end of the lever 52 is mounted in the fork groove 514 via a connecting shaft 7. The fork groove 514 provides space for rotation between the lever 52 and the fork 51. In this example, the lever 51 moves along the first direction within the slide rail by the handle 4, causing the fork 51 to move in the first direction, changing the angle between the fork 51 and the lever 52, thus causing the lever 52 to rotate. The lever 52 rotates around the fixed shaft 9 in the unlocking direction, thereby moving the unlocking mechanism 3 and unlocking the lock body.

[0046] In one embodiment, referring to Figures 3 and 5, the pull rod 52 includes a pull rod body 521 and a connecting section 522 extending from one side of the pull rod body 521; the pull rod body 521 is connected to the unlocking mechanism 3, the connecting section 522 is provided with a first mounting groove 523 arranged in a second direction, the fixed shaft 9 passes through the first mounting groove 523, one end of the connecting section 522 is provided with a second mounting groove 524 arranged in a third direction, and the second end of the fork 51 is movably connected in the second mounting groove 524.

[0047] As an example, the lever 52 includes a lever body 521 and a connecting section 522. The lever body 521 is connected to the unlocking mechanism 3. The connecting section 522 extends from one side of the lever body 521. Specifically, the connecting section 522 has a first mounting groove 523 at its corner, which is arranged in a second direction. The fixed shaft 9 passes through the first mounting groove 523. One end of the connecting section 522 has a second mounting groove 524, which is arranged in a third direction. The second end of the fork 51 is movably connected to the second mounting groove 524. With this configuration, when the fork 51 moves in the first direction, it can drive the connecting section 522 to rotate clockwise or counterclockwise around the fixed shaft 9 in the first mounting groove 523, i.e., rotate in the unlocking direction, so as to drive the lever body 521 to move in the first direction, thereby controlling the unlocking mechanism 3 to unlock the lock body. Specifically, the second mounting groove 524 and the fork groove 514 are cross-fitted to provide room for rotation between the lever 52 and the fork 51.

[0048] In one embodiment, referring to Figures 1, 2 and 3, the unlocking device further includes a reset member 10, which is disposed on the fixed shaft 9 and connected to the transmission mechanism 5, for controlling the reset of the transmission mechanism 5.

[0049] As an example, the unlocking device also includes a reset member 10. During installation, the reset member 10 is placed on the fixed shaft 9 and connected to the transmission mechanism 5. Specifically, it is installed on the fixed shaft 9 in the first mounting groove 523 of the connecting section 522. One end of the reset member 10 is connected to the connecting section 522, and the other end is connected to the fixed shaft 9. In use, the handle 4 moves in the slide rail along the first direction, thereby driving the fork 51 to move along the first direction, changing the angle between the fork 51 and the pull rod 52, thereby causing the pull rod 52 to rotate, so as to control the unlocking mechanism 3 to unlock the lock body. During this process, the connecting section 522 of the pull rod 52 rotates clockwise or counterclockwise around the fixed shaft 9, that is, it rotates in the unlocking direction, and the reset member 10 is pressed to generate a reset force. Using the reset capability provided by the reset member 10, the connecting section 522 rotates counterclockwise or clockwise around the fixed shaft 9 of the first mounting groove 523, that is, it rotates in the reset direction, so as to drive the pull rod body 521 to move in the opposite direction of the first direction, thereby realizing the reset of the transmission mechanism 5.

[0050] In one embodiment, referring to Figures 1, 2 and 3, the reset member 10 includes a return spring, which is sleeved on the fixed shaft 9. One end of the return spring is connected to the support seat 1, and the other end of the return spring is connected to the pull rod 52. The return spring is used to drive the pull rod 52 to rotate around the fixed shaft 9 in the reset direction, so as to drive the unlocking mechanism 3 to reset. The reset direction is opposite to the unlocking direction.

[0051] As an example, the reset component 10 includes a return spring; during installation, the return spring is sleeved on the fixed shaft 9, with one end of the return spring connected to the support base 1 and the other end connected to the pull rod 52. Specifically, the return spring is installed on the fixed shaft 9 within the first mounting groove 523 of the connecting section 522, with one end of the return spring connected to the connecting section 522 and the other end connected to the fixed shaft 9. In use, the handle 4 moves along the slide rail in the first direction, thereby driving the fork 51 to move in the first direction, changing the angle between the fork 51 and the lever 52, causing the lever 52 to rotate around the fixed shaft 9 in the unlocking direction, thereby driving the unlocking mechanism 3 to move and controlling the unlocking mechanism 3 to unlock the lock body. During this process, the connecting section 522 of the lever 52 rotates clockwise or counterclockwise around the fixed shaft 9, i.e., rotates in the unlocking direction, while the return spring is compressed to generate elastic force. Using the elastic force provided by the return spring, the connecting section 522 rotates counterclockwise or clockwise around the fixed shaft 9 of the first mounting groove 523, i.e., rotates in the reset direction, thereby driving the lever body 521 to move in the opposite direction of the first direction, thereby resetting the transmission mechanism 5.

[0052] In one embodiment, referring to FIG1, the unlocking device includes a damping component 6; the damping component 6 is disposed between the support base 1 and the handle 4.

[0053] As an example, the unlocking device includes a damping component 6; during installation, the damping component 6 is placed between the support base 1 and the handle 4, which can dampen the pushing and pulling process of the handle 4, improve the operating feel and the return effect of the handle 4.

[0054] In one embodiment, referring to FIG1, the damping assembly 6 includes a matching damping wheel 61 and a rack structure 62; the damping wheel 61 is mounted on the handle 4, and the rack structure 62 is disposed on the support base 1 along a first direction; or, the rack structure 62 is mounted on the handle 4, and the damping wheel 61 is disposed on the support base 1 along a first direction.

[0055] As an example, the damping assembly 6 includes a damping wheel 61 and a rack structure 62. During installation, the damping wheel 61 is mounted on the handle 4, and the rack structure 62 is arranged on the support base 1 along the first direction. The damping wheel 61 and the rack structure 62 match to achieve the damping function, playing a damping role in the pushing and pulling process of the handle 4, improving the operating feel and the return effect of the handle 4.

[0056] In one example, the rack structure 62 is mounted on the handle 4, and the damping wheel 61 is arranged on the support 1 along the first direction, which can also achieve the above function.

[0057] This application provides a vehicle door assembly, referring to Figures 1 and 6, including a vehicle door, a lock body, and an unlocking device; both the unlocking device and the lock body are installed on the vehicle door, and the unlocking device is used to unlock the lock body.

[0058] As an example, the door assembly includes a door, a lock body, and an unlocking device. Both the unlocking device and the lock body are mounted on the door, positioned opposite each other, allowing the door lock body to be unlocked via the unlocking device. The unlocking device specifically includes a support base 1, a sliding mechanism 2, an unlocking mechanism 3, and a handle 4. During installation, the sliding mechanism 2 and the unlocking mechanism 3 are mounted on the support base 1, and the handle 4 is slidably connected to the sliding mechanism 2, allowing the handle 4 to move along a first direction (i.e., the sliding direction). The handle 4 is also connected to the unlocking mechanism 3. When the user operates the handle 4 to slide it along the first direction, the unlocking mechanism 3 connected to it can be controlled to unlock or unlock the lock body, thereby unlocking the door lock body. Compared to traditional solutions, the unlocking device in this example reduces space occupation through the horizontal movement of the handle 4, avoiding restrictions on other components or passenger seating space, and improving space utilization. It has a compact structure, occupies little space, has a novel appearance, and offers greater design freedom, increasing the creative space inside the door. It also has a more unique shape and aesthetic appeal, increasing the product's attractiveness and uniqueness.

[0059] In one embodiment, referring to FIG1, the door assembly further includes a trim panel 8, which is mounted on the door; an unlocking device is mounted on the trim panel 8.

[0060] As an example, the door assembly also includes a trim panel 8, which is mounted on the door; an unlocking device is mounted on the trim panel 8, so that the door lock can be unlocked by controlling the unlocking device. The trim panel 8 can cover and decorate the unlocking device, improving its appearance visibility. The unlocking device specifically includes a support base 1, a sliding mechanism 2, an unlocking mechanism 3, and a handle 4. During installation, the sliding mechanism 2 and the unlocking mechanism 3 are mounted on the support base 1, and the handle 4 is slidably connected to the sliding mechanism 2, allowing the handle 4 to move along a first direction (i.e., the sliding direction). The handle 4 is also connected to the unlocking mechanism 3. When the user operates the handle 4 to slide it along the first direction, the unlocking mechanism 3 connected to it can be controlled to unlock or unlock the lock body, thereby unlocking the car door. Compared with traditional solutions, the unlocking device in this example can reduce space occupation through the horizontal movement of the handle 4, avoiding restrictions on the seating space of other components or passengers, and improving space utilization. It has a compact structure, occupies little space, has a novel appearance, and allows for greater freedom in design, increasing the creative space inside the car door. It has a more unique shape and aesthetics, which can increase the product's attractiveness and uniqueness.

[0061] The specific implementation process in this example is as follows: the handle 4 is connected to the fork 51 and is locked on the slide rail. When the passenger operates the handle 4, the fork 51 moves forward along the slide rail. The fork 51 drives the lever 52 to rotate around the fixed shaft 9. The lever 52 rotates and presses the return spring. The lever 52 rotates and drives the cable ball head 32 to move forward, which in turn drives the cable 31 and the limit guide sleeve 33 to unlock the door lock. After the passenger unlocks the door, the handle 4 is released, the pressure of the return spring is released, and the lever 52 returns to its original position. The return of the lever 52 drives the fork 51 and the cable ball head 32 to move backward. At this time, the cable 31 and the limit guide sleeve 33 are reset, and the handle 4 also returns to its original position.

[0062] This application provides an automobile, including a door assembly.

[0063] As an example, the door assembly includes a door, a lock body, and an unlocking device. Both the unlocking device and the lock body are mounted on the door, positioned opposite each other, allowing the door lock body to be unlocked via the unlocking device. The unlocking device specifically includes a support base 1, a sliding mechanism 2, an unlocking mechanism 3, and a handle 4. During installation, the sliding mechanism 2 and the unlocking mechanism 3 are mounted on the support base 1, and the handle 4 is slidably connected to the sliding mechanism 2, allowing the handle 4 to move along a first direction (i.e., the sliding direction). The handle 4 is also connected to the unlocking mechanism 3. When the user operates the handle 4 to slide it along the first direction, the unlocking mechanism 3 connected to it can be controlled to unlock or unlock the lock body, thereby unlocking the door lock body. Compared to traditional solutions, the unlocking device in this example reduces space occupation through the horizontal movement of the handle 4, avoiding restrictions on other components or passenger seating space, and improving space utilization. It has a compact structure, occupies little space, has a novel appearance, and offers greater design freedom, increasing the creative space inside the door. It also has a more unique shape and aesthetic appeal, increasing the product's attractiveness and uniqueness.

[0064] The specific implementation process in this example is as follows: the handle 4 is connected to the fork 51 and is locked on the slide rail. When the passenger operates the handle 4, the fork 51 moves forward along the slide rail. The fork 51 drives the lever 52 to rotate around the fixed shaft 9. The lever 52 rotates and presses the return spring. The lever 52 rotates and drives the cable ball head 32 to move forward, which in turn drives the cable 31 and the limit guide sleeve 33 to unlock the door lock. After the passenger unlocks the door, the handle 4 is released, the pressure of the return spring is released, and the lever 52 returns to its original position. The return of the lever 52 drives the fork 51 and the cable ball head 32 to move backward. At this time, the cable 31 and the limit guide sleeve 33 are reset, and the handle 4 also returns to its original position.
