Abstract

The invention relates to a self-protection opening and closing driving device. The device comprises a motor, an output shaft and a self-protection transmission assembly, wherein the self-protection transmission assembly further comprises a driving gear, a second gear and an elastic arm, and the elastic arm is clamped to a first gear with certain retention force. Compared with the prior art, an original possible tooth sliding phenomenon is replaced by deformation of the elastic arms, protection measures are provided for the whole self-protection opening and closing driving device, the whole self-protection opening and closing driving device can repeatedly deal with the sudden change force situation, meanwhile, normal use of the whole device is not affected, phenomena of gear tooth sliding abrasion and the like are avoided, and the service life is greatly prolonged, and good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of drive components, in particular to a self-protection switch drive device. Background technique [0002] Many articles in life need to be opened in a rotating manner, such as revolving doors, windows, washing machines, storage boxes in cars, etc., which usually have an opening and closing part like a clamshell and a driving device that drives its motion. The driving device generally uses an electric motor as a power source for generating torque. The electric motor is connected to an output shaft through a multi-stage gear transmission, and the rotation of the opening and closing parts is controlled by the output shaft. [0003] For example, Chinese invention patent CN111743446B discloses an opening and closing member driving device and a toilet lid opening and closing unit. Miniaturization in the direction orthogonal to the direction. At the same time, its motor is configured such that the rotating shaft...
