The lifting driving mechanism comprises a telescopic outer sleeve, an opening is formed in the bottom of the telescopic outer sleeve, and a driving unit is arranged at the top of the telescopic outer sleeve; the lead screw is arranged in the telescopic outer sleeve, the top end of the lead screw is connected with the driving unit, and the lead screw is sleeved with a lead screw nut; and the telescopic inner sleeve is arranged in the telescopic outer sleeve and can only axially move relative to the telescopic outer sleeve, and the telescopic inner sleeve is connected with the lead screw nut. Compared with the prior art, the telescopic sleeve structure driven by the lead screw is designed, after the driving unit works, the lead screw is driven to rotate, a lead screw nut on the lead screw converts rotary motion into vertical linear motion, the telescopic inner sleeve is driven to extend or retract from the bottom of the telescopic outer sleeve, and linear driving is achieved; the structure is integrally compact, small in occupied space, high in operation precision and high in bearing capacity.
本发明涉及一种升降驱动机构,包括伸缩外套管,所述伸缩外套管的底部开口,顶部设置有驱动单元;丝杆,设置于所述伸缩外套管内部,并且顶端连接所述驱动单元,所述丝杆上套设有丝杠螺母;伸缩内套管,设置于所述伸缩外套管内,且仅可相对所述伸缩外套管轴向移动,所述伸缩内套管连接所述丝杠螺母。与现有技术相比,本发明设计了由丝杆驱动的伸缩套管结构,驱动单元工作后,带动丝杆旋转,丝杆上的丝杠螺母将旋转运动转变为上下直线运动,驱动伸缩内套管从伸缩外套管底部伸长或者回缩,实现直线驱动;该结构整体紧凑,占用空间小,运行精度高而且承重能力强。
