The invention discloses an electric adjusting mechanism for an automobile seat backrest. The electric adjusting mechanism includes a motor and a rack, the motor is fixedly connected with an automobilebody through a support. An output shaft of the motor is fixedly connected with a driving gear; a rotatable driven gear is further installed on the support, the driving gear is meshed with the drivengear, the driven gear is meshed with the rack to enable the rack to slide relative to the support, a lock catch plate is fixedly connected to the rack, a lock catch hole is formed in the lock catch plate, and the lock catch hole can be connected with a lock hook installed on an automobile seat in a hung mode. According to the technical scheme of the invention, the meshing position of the driven gear and the rack is changed through the output torque of the motor; automatic control over angle adjustment of the automobile seat backrest is achieved, time and labor are saved, abnormal sounds generated in the angle adjusting process of the automobile seat backrest are reduced through the measures that the silencing bush is arranged, and the convex teeth on the rack are arranged along the arc line, and the comfort degree of passengers is improved.

    本发明公开的一种汽车座椅靠背电动调节机构,包括电机和齿条,电机通过支架与汽车车身固定连接,电机输出轴上固定连接有主动齿轮,支架上还安装有可转动的从动齿轮,主动齿轮与从动齿轮相互啮合,从动齿轮与齿条相互啮合使齿条能够相对于支架滑动,齿条上固定连接有锁扣板,锁扣板上设置有锁扣孔,锁扣孔能够与安装在汽车座椅上的锁钩挂接在一起。采用本发明的技术方案,通过电机输出力矩来改变从动齿轮与齿条的啮合位置,实现了对汽车座椅靠背角度调节的自动化控制,省时省力,通过设置消音衬套、将齿条上凸齿设置为沿弧线排列等措施减少了汽车座椅靠背在调节角度过程中出现的异响,提升了乘客舒适度。
