Technical Field

[0001] The utility model relates to a self-priming structure of a car door lock with a clutch function. Background Art

[0002] With the development of the automobile industry, the functions and types of automobile door locks are becoming increasingly diverse, passengers' knowledge of automobiles is increasing, and their requirements for automobile comfort are also getting higher and higher. Among them, for car doors, humanized opening and closing are receiving more and more attention from customers and vehicle companies.

[0003] Traditional car door locks have the following problems: First, when closing the door, due to the closing resistance of the car parts, a large force is required to close the door. In actual use, the door lock is often only in a half-locked state, not fully locked, which poses a great safety hazard. Second, during the door lock opening and closing process, the noise generated by the collision brings discomfort to people and affects its service life.

[0004] At the same time, in case of emergency or electrical failure, the power is suddenly cut off during the self-priming process, or the motor fails and needs to be unlocked. Because the self-priming motor cannot be reset, the ratchet will be pushed up by the self-priming push rod and cannot return to its position.

[0005] In view of the above problems, it is necessary to improve the existing automobile door locks and propose a self-priming structure of an automobile door lock with a clutch function. Utility Model Content

[0009] The utility model realizes the self-priming operation of the vehicle lock through the action of the self-priming mechanism, and completes the clutch operation of the vehicle lock through the action of the clutch mechanism.

[0010] Preferably, a self-priming rocker arm is provided with a self-priming rocker arm mortise shaft, and the self-priming rocker arm rotates around the self-priming rocker arm mortise shaft as the center of a circle. An extrusion structure is provided at one end of the self-priming rocker arm, and a fixed structure three is provided on one side of the self-priming conversion arm. The self-priming rocker arm pushes the fixed structure three through the extrusion structure to rotate the self-priming conversion arm.

[0011] This arrangement drives the self-priming conversion arm to rotate through the action of the self-priming rocker arm, thereby causing the self-priming push rod to move.

[0012] Preferably, the self-priming conversion arm is provided with a self-priming conversion arm shaft, the self-priming conversion arm shaft is provided with a self-priming reset torsion spring, the self-priming conversion arm is provided with a fixed structure 1, the self-priming push rod is provided with a fixed structure 2, and the two ends of the self-priming reset torsion spring are respectively connected to the fixed structure 1 and the fixed structure 2.

[0013] This arrangement, through the action of the self-priming reset torsion spring, allows the self-priming conversion arm and the self-priming push rod to always maintain a certain angle, and also allows the self-priming push rod to always move in the direction of the ratchet.

[0014] Preferably, a fixing structure four is provided at one end of the self-priming push rod, and a ratchet self-priming shaft matching with the fixing structure four is provided on the ratchet.

[0015] This arrangement, through the action of the fixing structure four and the ratchet self-priming shaft, increases the stability of the connection between the self-priming push rod and the ratchet, making it easier for the self-priming push rod to complete the self-priming operation.

[0016] Preferably, a ratchet limiting shaft is provided at one end of the clutch arm, and the clutch arm rotates around the ratchet limiting shaft as the axis. Clutch arm shaft one and clutch arm shaft two are installed on the clutch arm. Clutch arm shaft one cooperates with the self-priming push rod, and clutch arm shaft two cooperates with the unlocking transmission arm. The unlocking transmission arm pushes the clutch arm to move through the clutch arm shaft two.

[0017] This setting, by unlocking the transmission arm, pushes the clutch arm shaft 2 to move, so that the clutch arm shaft 1 of the clutch arm pushes the zizi push rod to move, so that the fixed structure 4 of the self-priming push rod is separated from the ratchet self-priming shaft, thereby releasing the self-priming function of the self-priming push rod, realizing the clutch of the ratchet, and allowing the car door to open normally.

[0018] Preferably, the lock sensor is arranged on one side of the pawl.

[0019] The sensor detects the motion state or rotation position of the pawl, which facilitates the subsequent operation of the self-priming mechanism.
