Abstract
An electronic lock transmission structure, an electronic lock and a motor vehicle, including: a drive device with an output shaft; a transmission mechanism including an input end and an output end, and the input end is a transmission assembly connected to the output shaft, and the output end is a cam device; a lock rod, and one end of which is a free end, and the other end of which is connected to the cam device; and rotation of the output shaft is converted into a reciprocating movement of the lock rod through the transmission mechanism. The disclosed electronic lock transmission structure adopts a first worm and a second worm for transmission, which may provide a larger speed reduction ratio, thereby outputting a larger ejection force.
Claims16
An electronic lock transmission structure, comprising:
