Abstract

The invention belongs to the field of automobile door lock systems, and specifically relates to a side door lock transmission mechanism, which includes a bottom plate, on which a ratchet riveting shaft and a pawl riveting shaft are fixed, and the ratchet is rotatably connected to the ratchet riveting shaft. The claw is rotatably connected to the ratchet riveting shaft, and the front claw end of the ratchet leans against the locking and engaging arc surface of the ratchet wheel; a drive shaft is arranged on the end of the bottom plate away from the ratchet riveting shaft to rotate. The cam is connected to the transmission shaft with an interference fit, and a slider positioning shaft is arranged on the bottom plate corresponding to the bottom of the transmission shaft. The structure of the product of the present invention is simple and compact, and the transmission force can be effectively reduced by setting the connecting rod slider cam structure on the bottom plate, the structure is simple, and the transmission efficiency and transmission stability are greatly improved.

Description

technical field [0001] The utility model 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 utility model 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...
