The guide member 130 moves downward; the wedge-shaped transmission member 100 pushes the adapter member 300 (such as a booster) during the downward movement; the adapter member 300 pushes the clutch member 400 (such as the lock body transmission gear) along the guide rod 200 moves so as to leave the plane where its meshing position is located, and is disengaged from the lock body switch lock gear (not shown in the figure); after disengagement, the key drives the lock body switch lock gear to rotate, thereby realizing unlocking. During the process that the adapter member 300 pushes the clutch member 400 to move, the clutch member 400 compresses the elastic member 500 .

After the unlocking is completed, the key is reversed, which drives the wedge-shaped transmission member 100 to move upward; the clutch member 400 is driven by the restoring force of the elastic member 500, moves in the opposite direction, is pushed back to the plane where the fitting position is located, and is pressed into the lock body again. How to achieve homing in the switch lock gear. In this process, even if there is a tolerance (for example, the optional error angle caused by the slight rotation of the motor), the clutch member 400 can realize the connection between the transmission gear and the lock body switch lock gear under the action of the restoring force of the elastic member. Correctly homing.

According to the exemplary embodiment of the present application, the clutching process of the lock body 2000 through the second side (eg, the door inner handle) is as follows: the rotation of the door inner handle drives the second transmission member 142 on the wedge-shaped transmission member 100 along the transmission mechanism through the transmission mechanism. The guide member 130 moves upward; the wedge-shaped transmission member 100 pushes the adapter member 300 (such as a booster) during the upward movement; the adapter member 300 pushes the clutch member 400 (such as the lock body transmission gear) along the guide rod 200 Move, so as to leave the plane where its meshing position is located, and disengage from the lock body switch lock gear (not shown in the figure); after disengagement, the key drives the lock body switch lock gear to rotate, thereby realizing unlocking. During the process that the adapter member 300 pushes the clutch member 400 to move, the clutch member 400 compresses the elastic member 500 .

After the unlocking is completed, the inner handle of the door rebounds, driving the wedge-shaped transmission member 100 to move downward during the rebounding process; the clutch member 400 moves in the opposite direction and is pushed back to the plane where the fitting position is located under the push of the restoring force of the elastic member 500 , is pressed into the lock gear of the lock body switch again, and how can it achieve homing. In this process, even if there is a tolerance (for example, the optional error angle caused by the slight rotation of the motor), the clutch member 400 can realize the connection between the transmission gear and the lock body switch lock gear under the action of the restoring force of the elastic member. Correctly homing.

According to another aspect of the present application, there is also provided an automatic lock, comprising the above lock body.

Compared with the traditional gear transmission clutch structure, the wedge-shaped transmission component, the clutch structure, the lock body and the automatic lock for the lock body provided by the present application have simpler structure and more convenient installation; there is no safety dead point, and can stop at the The key and the door handle can be opened quickly in any state, thereby improving safety and enhancing the user experience; through a set of clutch mechanisms, the key and the door handle can be opened at the same time, making the structure more compact and the cost further reduced; The reducer adopts the gearbox structure, the internal sealing and lubrication, the life is more guaranteed, and the precision control is good; the clutch components are driven by the large gear structure, and the lubrication and transmission coordination accuracy requirements are lower, and the service life is longer.
