Abstract

The invention belongs to the field of automobile door lock systems, and particularly relates to a side door lock transmission mechanism. The mechanism comprises a baseplate, wherein a ratchet wheel riveting shaft and a ratchet pawl riveting shaft are fixed on the baseplate; a ratchet wheel is rotationally connected onto the ratchet wheel riveting shaft; the ratchet pawl is rotationally connected onto the ratchet pawl riveting shaft; the front part pawl end of the ratchet pawl is propped against the locking meshing cambered surface of the ratchet wheel; a transmission shaft is rotationally arranged at the end part on the side of the baseplate away from the ratchet pawl riveting shaft; a transmission cam is connected onto the transmission shaft in an interference fitting manner; a sliding block positioning shaft is arranged at the lower part, corresponding to the transmission shaft, of the baseplate. The mechanism is simple and compact in structure, can reduce the transmission force effectively through the arrangement of a connecting rod sliding block cam on the base plate, is simple in structure, and can improve the transmission efficiency and the transmission stability greatly.

Description

technical field [0001] The invention belongs to the field of automobile door lock systems, in particular to a side door lock transmission mechanism. 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. The lock ratchet drives the lock into a fully locked state. [0003] The existing functional mechanisms for dragging in the clamping plate 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. The gear reduction ratio accomplishes this function. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a simple, ingenious and reasonable side door lock transmission mechanism, which can greatly improve the transmission effi...
