The invention belongs to the field of automobile seat adjustment, and particularly relates to an automobile seat backrest angle adjusting mechanism which comprises a base, supporting plates are fixed to the front side and the rear side of the top of the base, a vertical plate is arranged between the two supporting plates, and the tail end of the vertical plate is fixedly sleeved with the outer wall of a rotating shaft. The two ends of the rotating shaft are rotationally connected with the inner walls of the two vertical plates correspondingly. A weighing sensor and a pressure sensor are used for doubly feeding back the weight of a user and the pressure of the thickness on a vertical plate, so that a lead screw motor can be automatically started to drive a lead screw sliding block to move, a spur rack drives a second gear to rotate, and then a first gear is driven to rotate; therefore, the rotating shaft can drive the vertical plate for adjustment, the angle of the seat can be adjusted, automatic adjustment is achieved, operation is convenient and fast, manual adjustment is not needed, driving danger is reduced, meanwhile, adjustment buttons do not need to be installed, and the situation that the buttons are frequently damaged due to operation is avoided.
本发明属于汽车座椅调节领域,具体为一种汽车座椅靠背角度调节机构,包括底座,所述底座的顶部前后侧均固定有支板,两组所述支板之间置有竖板,所述竖板的尾端固定套装有转轴的外壁,所述转轴的两端分别与两组所述竖板的内壁转动连接。本发明通过称重传感器和压力传感器进行双重反馈使用者的体重以及厚度对竖板的压力,从而能够实现自动启动丝杆电机带动丝杆滑块移动,从而使得直齿条带动第二齿轮转动,进而带动第一齿轮转动,从而能够使得转轴带动竖板进行调节,从而实现调节座椅的角度,自动化调节,操作方便快捷,无需人工手动调节,降低了驾驶的危险性,同时无需安装调节按钮,避免按钮操作频繁损坏的情况发生。
