The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention is further illustrated with reference to the accompanying figures 1 to 5:

in a first mode

The invention provides a vehicle lock clutch structure, which combines with figures 1 to 5, a rotating piece 1, a clutch piece 2 driven by the rotating piece 1 and a lock tongue 8 positioned on the travel track of the clutch piece 2,

the clutch piece 2 is rotatably arranged on the first side surface of the rotating piece 1; the position of the clutch part 2 rotates, and the clutch part is contacted with the lock tongue 8 on the stroke track to form a first toggle structure, or is separated from the lock tongue 8 on the stroke track to form a separation structure.

The mode can solve the problems that the traditional motor vehicle door lock transmission structure is complex, the occupied space on the vehicle door is more, and the installation and maintenance are very inconvenient.

The vehicle lock clutch structure enables the motor vehicle door lock to have higher integration level, and is convenient for installation, maintenance and inspection of the motor vehicle door lock, wherein the vehicle lock clutch structure omits a complex transmission connecting rod part, the clutch part 2 is directly arranged on the rotating part 1, and can transmit the action energy of the lock bolt, thereby being beneficial to reducing the volume and the weight of the whole vehicle lock, and being convenient and practical; with the aid of the clutch 2, the entire process of locking and unlocking the door does not rely too much on the drive motor, and the door can be used even if the drive motor fails or is damaged.

It will be appreciated that "rotatable" in the sense that the clutch member 2 is rotatably arranged on the first side of the rotary member 1, it will be appreciated that the clutch member 2 does not rotate without intervention, i.e. the transfer of kinetic energy between the clutch member 2 and the bolt is not interrupted.

It should be noted that the form of the clutch structure of the present lock is various, and we provide several alternatives below.

Mode two

The difference between the present mode and the first mode is that, with reference to fig. 1 to 5, the rotating member 1 is coaxially and movably connected to the lock tongue 8 having a clamping platform 9, and the lock tongue 8 and the rotating member 1 are arranged in a stacked manner;
