A new single-motor-driven unlocking and folding mechanism and its application

Abstract

The novel single-motor-driven unlocking and folding mechanism disclosed by the present invention comprises a drive motor fixedly mounted on the upper connection plate in the seat back, the drive motor has an output shaft, and a stroke is fixed on the output shaft Control module: a stroke control bracket fixed on the lower connecting plate in the seat cushion, before unlocking, the stroke control module is idling relative to the stroke control bracket, after unlocking, the stroke control bracket generates resistance to the rotation of the stroke control module, using The reaction force forces the drive motor to drive the upper connecting plate in the seat back to fold over. The novel single-motor-driven unlocking and folding mechanism of the present invention only needs to fix the stroke control module on the output shaft of the drive motor and the stroke control bracket installed on the lower connecting plate in the seat cushion to realize the unlocking of the seat It has the advantages of less mechanism parts, simple transmission relationship, which is beneficial to the layout of the whole chair and reduces the cost of quality control.

Description

technical field [0001] The invention relates to the technical field of car seat design, in particular to a novel single-motor unlocking and folding mechanism and its application. Background technique [0002] At present, with the development of the automobile industry and the changes in the automobile market, the demand for seven-seater cars is increasing. The seven-seater cars of the seven-seater models of major automobile manufacturers have been pushed to the market one after another. Among the seven-seater models, the user-friendly functional configuration of the middle and rear seats has become a means for OEMs to attract end consumers under the new normal. Such as the electric folding function of the middle and rear seats. [0003] At present, there are mainly two adjustment methods for the fold-flat function of the middle and rear seats: [0004] 1. Manual adjustment to realize the action of unlocking and laying down. [0005] In the actual use process, manual oper...

AI Technical Summary

Problems solved by technology

[0023] One of the technical problems to be solved by the present invention is that the existing single-motor-driven unlocking and folding mechanism has many mechanism parts, the transmission relationship is complicated, and the arrangement on the seat requires a large space, which is not conducive to the arrangement of the whole chair. A novel single-motor-driven unlocking and folding mechanism with fewer mechanical parts, a simple transmission relationship, which facilitates the layout of the entire chair and reduces quality control costs is provided to solve problems such as bringing more quality control costs.
