Abstract

The invention belongs to the field of automobile door lock systems, and particularly relates to a transmission mechanism of a self-suction tail door lock. The transmission mechanism of the self-suction tail door lock comprises a bottom plate, and a drive plate rivet shaft, a pawl rivet shaft and a ratchet wheel rivet shaft are formed on one side surface of the bottom plate. A drive plate is rotatably connected to the drive plate rivet shaft through a mounting hole formed in the end of the drive plate. An arc-shaped protrusion is arranged at the outer end, corresponding to the drive plate rivet shaft, of the bottom plate. A transmission rocker arm is rotatably connected to an external driving motor gear case through a transmission rocker arm shaft which is integrally connected at the end of the transmission rocker arm, and the outer side cambered surface of the transmission rocker arm abuts against a first protruding shoulder of the drive plate. A transmission gasket shaft is fixed on the inner side, corresponding to the drive plate rivet shaft, of the drive plate, and a transmission gasket is connected to the transmission gasket shaft in a rotating mode. The transmission mechanism of the self-suction tail door lock is simple and compact in structure, a connecting rod and cam structure is arranged on the bottom plate, driving force can be effectively lowered, the structure is simple, and the transmission efficiency and the transmission stability are greatly improved.

Description

technical field [0001] The invention belongs to the field of automobile door lock systems, in particular to a transmission mechanism of a self-priming tailgate lock. Background technique [0002] The function of electric dragging into the clamp is a new type of car door lock function produced with the development of control technology. Its principle is that when the door is not completely closed (in a half-lock state), the motor on the tailgate lock The ratchet of the door lock drives the buckle into a fully locked state. [0003] The existing functional mechanisms for dragging in the pallet are all rotated through the center of the connecting rod, and finally realize this function by driving the ratchet. The structure is complex, the work reliability is poor, and the required transmission force is large, so a larger motor is required. And gear reduction ratio to achieve this function. Contents of the invention [0004] The purpose of the present invention is to overcome...
