Abstract

The present invention provides a lockable rotary drive mechanism, an electric rotary seat and an automobile. The rotary drive mechanism of the present invention includes a fixed bracket, a rotary bearing plate fixedly connected with the fixed bracket and having an inner ring, and a The locking disc with several protrusions is fixedly connected, and a wedge-shaped space is formed between the adjacent protrusions, which is jointly surrounded by the locking disc and the fixing bracket, and the wedge-shaped space is provided with a rigid sealing body and an elastic reset piece and the rotary drive mechanism also includes a rotary drive module fixedly connected to the fixed bracket, and a shift fork connected to the power output end of the rotary drive module. The rotary driving mechanism of the present invention has a locking function and can provide relatively large locking torque, thereby overcoming the shortcoming of insufficient locking torque in the prior art.

Description

technical field

[0001] The present invention relates to the technical field of electric swivel seats, in particular to a lockable rotary drive mechanism that can be used to drive the seat to rotate. Cars with this seat. Background technique

[0002] In order to improve the convenience of car seats, electric swivel seats have become the research and development direction of some car companies. At present, in the concept electric swivel seats, the motor drives the seat frame to rotate through the gear and ring gear structure. The rotatable adjustment of the seat is realized, and the locking feature of the worm-worm mechanism inside the motor is also used in the rotating direction of the seat, so as to indirectly realize the locking of the seat.

[0003] In the existing gear transmission structure, there are more or less gaps in the meshing between the gears, but for the electric rotating seat using gear transmission, due to the increase of the force arm, the gear meshing gap ...
