The invention relates to an automobile electric pedal mechanism which is mainly composed of a motor, a connecting rod mechanism and an anti-backlash spring which are installed in a base, a shell used as a pedal is installed over the base, a support cross beam is installed in the shell, and the lower portion of the support cross beam is connected with a fixed rotating shaft through a connecting piece. The connecting rod mechanism is composed of a transition push rod, a support rod and a rocker; a driving rod of the motor is connected with one end of the transition push rod, the other end of the transition push rod sleeves a fixed rotating shaft, two ends of the fixed rotating shaft are respectively hinged with the support rod and the rocker, one end of the anti-backlash spring is fixed on the base, and the other end of the anti-backlash spring sleeves the fixed rotating shaft. The mechanism is simple in structure, and the transition push rod can absorb part manufacturing and mounting errors to a certain extent; the opening angle can be controlled by the length of the motor screw, and a travel switch is not needed; the connecting rod mechanism decomposes/bears load, and the motor load is small; other locking and bearing structures do not need to be configured, and the cost is low; and the anti-backlash spring can effectively control the fit clearance of the automobile electric pedal mechanism at each working position.
本发明涉及一种汽车电动脚踏机构,主要由安装在基座内的电机、连杆机构和消隙弹簧组成,基座上方装有用于作为脚踏的壳体,壳体内装有支架横梁,其下方通过连接件与固定转轴相连;连杆机构由过渡推杆、支杆和摇杆组成,电机的驱动杆与过渡推杆的一端相连,过渡推杆的另一端套在固定转轴上,固定转轴的两端分别铰接支杆和摇杆,消隙弹簧一端固定在基座上,另一端套在固定转轴上。本发明结构简单,过渡推杆可一定程度的吸收对零件制造及安装误差;电机螺杆长度可控制开启角度,无需配置行程开关;连杆机构分解/承受载荷,电机负载小;无需配置其他锁止与承载结构,成本低;消隙弹簧可有效控制汽车电动脚踏机构在各工作位置时的配合间隙。
