The invention discloses an electric quick folding mechanism for an automobile seat backrest, which belongs to the technical field of automobile parts and comprises a folding assembly and a driving assembly which are arranged on the inner side of a seat backrest frame, one end of the folding assembly penetrates out of the seat backrest frame to be connected with an automobile body, and the other end of the folding assembly is connected with an output shaft of the driving assembly. According to the electric quick folding mechanism for the automobile seat backrest, the planet wheel principle is adopted, the speed reducing and torque increasing functions can be achieved, for the seat backrest with the large weight, by setting the corresponding transmission ratio, the output torque of the mechanism can be increased, backrest overturning is achieved, and the phenomena of too low motor generation efficiency and heating are avoided. Through the cooperation with the torsional spring, the time difference between putting down and lifting up of the seat backrest can be reduced, the lifting time is shortened, the output torque of the overall folding mechanism can be further increased, and rapid folding of the backrest with larger weight is achieved.

    本发明公开了一种汽车座椅靠背电动快速翻折机构,属于车辆零部件技术领域,包括设置在座椅靠背框架内侧的翻折总成和驱动总成,所述翻折总成一端穿出座椅靠背框架与车身连接,另一端与驱动总成的输出轴连接。本发明提供一种汽车座椅靠背电动快速翻折机构,采用行星轮原理,可以实现降速增扭功能,对于重量较大的座椅靠背,通过设置相应的传动比,可以使机构的输出力矩增大,实现靠背翻转,避免了电机产生效率过低、发热的现象。通过与扭簧配合,能够减小座椅靠背放倒和抬起的时间差,使抬起时间缩短,能够进一步增加此整体翻折机构的输出力矩,实现重量更大靠背的快速翻折。
