[0032] It has been found through long-term practice that the rocker arm 1 in the door lock block is usually connected with rivets, which are non-detachable. As a result, when a failure occurs, the rivets can only be replaced, resulting in increased maintenance costs and waste of the door lock assembly; some structures also use a detachable structure, but the structure is relatively complex, and usually has a special limiting component to prevent the rocker arm 1 from detaching, resulting in a large number of components and complicated disassembly; the purpose of the utility model is to provide a rocker arm structure, a car door lock and a car, which can solve the problems existing in the prior art.

[0033] In view of this, the utility model aims to propose a rocker arm structure, comprising: a shell 3, a rocker arm 1 and a mounting member 2, the mounting member 2 comprising a connecting shaft 21 and a limiting portion 22; the connecting shaft is connected to the shell 3, and the limiting portion 22 is connected to the shell 3 through the connecting shaft 21; the rocker arm 1 is provided with a connecting hole 11, the connecting hole 11 is sleeved on the connecting shaft 21, and the limiting portion 22 is connected to the other side of the connecting shaft 21 relative to the shell 3; when the rocker arm 1 is configured, when the rocker arm 1 is in a working state, the rocker arm 1 can move relative to the connecting shaft 21 between the positions where the connecting hole 11 and the limiting portion 22 form an intersecting angle, and the limiting portion 22 can prevent the rocker arm 1 from disengaging from the connecting shaft 21; when the rocker arm 1 is in a non-working state, the rocker arm 1 can rotate to a disengagement position, the connecting hole 11 can pass through the limiting portion 22, and the rocker arm 1 can disengage from the mounting member.

[0034] The utility model provides a rocker arm 1 structure. When the rocker arm needs to be repaired, the position of the rocker arm is adjusted to make the rocker arm 1 in a non-working state, that is, the rocker arm 1 is adjusted back to the initial position, and the rocker arm 1 can be easily taken out without requiring to remove any extra fasteners. Therefore, the convenience of disassembly can be improved, thereby realizing rapid replacement and reducing the time and cost of repair. In the working state, the rocker arm 1 and the limiting portion 22 are always staggered through the cooperation of the cable 4 and the rocker arm 1, so that the stability of the rocker arm 1 can be ensured, and the rocker arm 1 can be prevented from being separated from the connecting shaft 21.

[0035] In the disclosed embodiment, a rocker arm structure is proposed for realizing a transmission function in a door lock block, specifically, for transmission between a cable 4 and an unlocking structure; the rocker arm structure includes a rocker arm 1 and a mounting member 2, the mounting member 2 includes a connecting shaft 21 and a limiting portion 22; the connecting shaft 21 is in the shape of a circular shaft, and the limiting portion 22 is in the shape of a sheet, connected to one end of the connecting shaft 21 to limit the axial position of the rocker arm 1 matched with the connecting shaft 21; the rocker arm 1 is formed with a connecting hole 11, and the shape of the connecting hole 11 is consistent with the shape of the limiting portion 22, so when installed, the connecting hole 11 is passed through the limiting portion 22 and is rotatably connected to the connecting shaft 21, specifically, when the connecting hole 11 passes through the limiting portion 22, the rocker arm is at a matching angle, and the rocker arm 1 is rotated by a specified angle so that the rocker arm 1 reaches a specified position, wherein the specified angle is an arbitrary angle not equal to zero, so that the connecting hole 11 and the limiting portion 22 form a staggered angle, so that the limiting portion 22 can prevent the rocker arm 1 from disengaging from the axial direction of the connecting shaft 21. Thus, it can be easily disassembled in case of maintenance, and when in use, the first end of the rocker arm 1 is used to connect with the cable 4 to achieve stable cooperation. Specifically, a cable installation hole 15 is formed at the first end of the rocker arm 1, and the cable installation hole 15 is used for hooking the cable 4; the second end of the rocker arm 1 is transmission-connected with the unlocking structure 5 through the connecting arm. When the first end of the rocker arm 1 is connected with the cable 4, the rocker arm 1 is at a first angle; the rocker arm 1 is at an initial angle when the door lock block is in use; when the user pries the door handle, thereby pulling the cable 4 connected to the door handle, when the cable 4 is pulled to the unlocking position, the rocker arm 1 is driven by the cable 4 to rotate to the unlocking angle, and the rotation direction to the unlocking angle is consistent with the direction of the matching angle to the specified angle, which can be counterclockwise.

[0036] The specific angle is calculated by the length of the cable 4 and the length of the rocker arm 1. When the rocker arm 1 is rotated to the opening angle, the second end of the rocker arm 1 cooperates with the unlocking structure 5 to open the door lock through transmission cooperation. The unlocking structure may refer to a component in the door lock block that controls the position of the lock tongue through the rocker arm structure. When disassembly is required, the rocker arm 1 is rotated back to the initial position so that the connection hole 11 of the rocker arm 1 corresponds to the position of the limit portion 22, and then the rocker arm 1 can be taken out from the axial direction of the connecting shaft 21, thereby realizing rapid replacement of parts without directly replacing the door lock block. The shell 3 may include a first shell and a second shell, and the connection and assembly are realized by snap-fitting between the first shell and the second shell. Specifically, the first shell may be an upper cover, and the second shell may be a mounting seat. After the components are assembled, the upper cover is closed on the mounting seat to achieve cooperation, wherein, as Figure 3 The housing shown is the first housing, i.e., the upper cover. Figure 4 The housing shown is a second housing, namely a mounting seat.

[0037] Among them, the inner contour of the connecting hole 11 and the outer contour of the limiting portion 22 have the same shape, and the area enclosed by the inner contour of the connecting hole 11 is larger than the area included by the outer contour of the limiting portion 22, thereby ensuring that the connecting hole 11 can pass through the limiting portion 22.

[0038] Furthermore, the limiting portion 22 includes a limiting protrusion, and a connecting groove is provided in the connecting hole 11; the connecting groove can pass through the limiting protrusion to achieve cooperation; when the rocker arm 1 is in a working state, the limiting protrusion and the connecting groove are alternately arranged; when the rocker arm 1 is in a non-working state, the rocker arm 1 rotates to the corresponding position of the protrusion and the connecting groove, and the rocker arm 1 can be separated from the limiting portion 22; or, the limiting portion 22 includes a limiting groove, and a connecting protrusion is provided on the inner wall of the connecting hole 11, which can also play the same role, that is, when the rocker arm 1 is in a working state, the limiting groove and the connecting protrusion are alternately arranged; when the rocker arm 1 is in a non-working state, the rocker arm 1 rotates to the corresponding position of the connecting protrusion and the limiting groove, and the rocker arm 1 can be separated from the limiting portion 22.

Correspondingly, when the cable 4 is pulled to the extreme position, the rocker arm 1 rotates to a second angle, the rocker arm 1 is located in the second position, and the second side 13 abuts against the second side wall 32 of the housing 3. Among them, the first angle and the second angle are the range of motion of the rocker arm, at this time, the corresponding door handle is at the maximum angle, and the car door lock is in an open state. Further, in order to ensure the stability of the rocker arm 1 during the rotation process, a support wall 33 is formed on the housing 3; one side of the rocker arm 1 abuts against the support wall 33, and the other side abuts against the connecting arm 16, thereby providing support for the rocker arm 1, which can improve its stability during rotation.
