The invention discloses a four-way waist support driver which comprises a support, an upper sliding plate and a lower sliding plate, the upper sliding plate and the lower sliding plate are arranged on the support from top to bottom and are both in up-down sliding fit with the support, a waist supporting piece is arranged between the upper sliding plate and the lower sliding plate, and first driving components are arranged on the upper sliding plate and the lower sliding plate. The first driving component is used for controlling the upper sliding plate to get close to or get away from the lower sliding plate, so that the waist supporting piece arches and falls back, a fixing base is arranged on the support below the lower sliding plate, a lifting lead screw is hinged to the fixing base through a pin shaft, the pin shaft is horizontally arranged and is parallel to the movement plane of the upper sliding plate and the movement plane of the lower sliding plate, and a small gear is in threaded connection with the lifting lead screw. The small gear and the lower sliding plate are vertically fixed and matched in a circumferential rotation mode, a transmission device used for driving the small gear to rotate is arranged on the lower sliding plate, and the effects of simplifying the machining technology, saving cost and expanding application occasions are achieved by hinging a certain end of the lifting lead screw.

    本发明公开了一种四向腰托驱动器,包括支架,支架上自上而下设置的上滑板和下滑板,上滑板和下滑板均与支架呈上、下滑动配合,上滑板和下滑板间有腰部支撑件,上滑板和下滑板上有第一驱动部件,第一驱动部件用于控制上滑板靠近、远离下滑板,使得腰部支撑件拱起、回落,下滑板下方的支架上设置有固定座,固定座通过销轴铰接有升降丝杆,销轴呈水平设置,且销轴与上滑板和下滑板的运动平面平行,升降丝杆上螺纹连接有小齿轮,小齿轮与下滑板呈竖向固定、周向转动配合,下滑板上设置有用于驱动小齿轮转动的传动装置,通过在升降丝杆上某一端进行铰接,实现简化加工工艺、节约成本和扩大应用场合的效果。
