Document Type and Number:
WIPO Patent Application WO/2023/051602
Kind Code:
A1
Abstract:
An electronic lock transmission structure, an electronic lock, and a motor vehicle. The electronic lock transmission structure comprises: a driving device (1), provided with an output shaft (2); a transmission mechanism, comprising an input end and an output end, the input end being a transmission component connected to the output shaft (2), and the output end being a cam device (4); and a lock rod (5), having one end being a free end, and the other end connected to the cam device (4). Rotation of the output shaft (2) is converted into reciprocating motion of the lock rod (5) by means of the transmission mechanism. According to the electronic lock transmission structure, a first worm (3) and a second worm (62) are used for transmission, such that a large reduction ratio can be provided, thereby outputting large ejection force. Moreover, the electronic lock is provided with a rack (8), and the rack (8) can drive a first gear (61) to be separated from the first worm (3) when the transmission mechanism of the whole electronic lock is stuck, such that the electronic lock is reset.
