Abstract (en)

[origin: EP4180596A1] The present disclosure relates to a transmission structure of a smart lock cylinder and a smart lock, including a lock shell assembly, a cylinder cam and a first transmission shaft. A first transmission member connected with the first transmission shaft and a first electric clutch device driving the first transmission member to connect or separate with the cylinder cam are arranged in the first transmission shaft. The first electric clutch device includes a drive motor, a worm fixedly connected with the output shaft of the drive motor, a nut sleeved on the worm and connected with the worm thread, and a double-layer spring. The worm, the nut and the double-layer spring are used to convert the kinetic energy of the motor into elastic potential energy to promote the connection or separation of the first transmission member and the cylinder cam.
