Abstract

The invention relates to the technical field of household appliances, and provides a transmission structure, a motor driving device and an intelligent door lock. The transmission structure comprises an engagement and disengagement assembly. The engagement and disengagement assembly comprises a first engagement and disengagement piece, a second engagement and disengagement piece and an elastic piece. The first engagement and disengagement piece and the second engagement and disengagement piece can be movably assembled in a manner of getting close to or away from each other relatively, and the elastic piece pushes against at least one of the first engagement and disengagement piece and the second engagement and disengagement piece, so that contact transmission of the first engagement and disengagement piece and the second engagement and disengagement piece is kept by the elastic piece. During use, the structure is simple, and the universality is high.

Description

technical field [0001] The present application relates to the field of household appliances, in particular to a transmission structure, a motor drive device and an intelligent door lock. Background technique [0002] With the rapid development of the smart home industry, smart single products have attracted widespread attention from consumers, among which smart door locks have great potential. Most of the current automatic door locks use programs to control the number of turns of the motor, and basically do not have a structural design to prevent motor stalling. Under normal circumstances, the motor drives the dead bolt of the lock body to rotate through the transmission structure. After reaching the limit position, the motor should stop working. If the motor still inputs the working current, the motor will stall, and the working current will double and cause the motor to be damaged. [0003] Therefore, the anti-blocking design plays a very important role in the life of th...
