The invention belongs to the technical field of jacks, and relates to an electric jack for a motor home, which comprises two obliquely arranged sliding rails, the downwards inclined ends of the two sliding rails are fixedly connected with positioning rings, the positioning rings and the corresponding sliding rails form annular rails, the interiors of the two rails are slidably connected with sliding shafts, an outer cylinder is fixedly connected between the two sliding shafts, and the outer cylinder is fixedly connected with the sliding rails. A driving assembly is arranged on the outer barrel and drives the inner barrel located in the outer barrel to slide on the outer barrel, a transmission assembly is arranged on one sliding rail and matched with the inner barrel, when the inner barrel slides, the transmission assembly drives the outer barrel to slide synchronously, and the end, extending out of the outer barrel, of the inner barrel is fixedly connected with a lifting base. The touring car has the advantages that the outer cylinder moves between the two sliding rails, the outer cylinder and the inner cylinder can be stored between the two sliding rails, and the outer cylinder is horizontally placed, so that the outer cylinder is transversely arranged on a chassis of the touring car and is far away from the ground, and the influence on the trafficability of the touring car is reduced.
本发明属于千斤顶技术领域,涉及房车用电动千斤顶,包括两个倾斜设置的滑轨,两个滑轨向下倾斜的一端均固定连接有定位环,定位环与对应的滑轨组成一个环形的轨道,两个轨道的内部均滑动连接有滑轴,两个滑轴之间固定连接有外筒,所述外筒上设置有驱动组件,驱动组件驱动位于外筒内的内筒在外筒上滑动,其中一个滑轨上设置有传动组件,传动组件与内筒配合,当内筒滑动时传动组件驱动外筒同步滑动,所述内筒伸出至外筒外部的一端固定连接有升降底座。本发明的优点在于:外筒向两个滑轨之间移动,能够将外筒和内筒均收纳至两个滑轨之间,使得外筒水平放置,从而横向设置在房车的底盘上,离地面较远,减少对房车通过性的影响。
