The invention belongs to the technical field of new energy automobiles, particularly relates to a jacking device for new energy automobile maintenance. For solving the problems that when an existing new energy automobile is maintained, the automobile needs to be jacked up through a jacking device, however, a contact point between an existing supporting device for jacking and the bottom of the new energy automobile has the hidden danger of connection looseness, and therefore the problem of safety during maintenance of the new energy automobile exists, the following scheme is provided: the device comprises a bottom plate and a connecting arm, a supporting column is fixedly connected to the outer wall of the top of the connecting arm, and fixing plates are fixedly connected to the outer walls of the two sides, close to the supporting column, of the connecting arm. By arranging a supporting ring, a vacuum pump and an air hole, when the new energy automobile is supported and jacked up, a hydraulic rod is adjusted to drive the supporting ring to make contact with the bottom of the new energy automobile, then air at the connecting point of the supporting ring and the bottom of the automobile is pumped out through the air hole through the vacuum pump, negative pressure adsorption is formed, and the tightness of the connecting point is improved; and therefore, the safety performance of the jacking device is improved.

    本发明属于新能源汽车技术领域,尤其是一种新能源汽车维修用顶起装置,针对现有的新能源汽车在维修时,需要通过顶起装置将汽车顶起,但是现有的顶起用支撑装置与新能源底部接触点存在有连接上的松动的隐患,因此,在进行新能源汽车维修时存在有安全问题,现提出以下方案,包括底板和连接臂,所述连接臂的顶部外壁固定连接有支撑柱,且连接臂靠近支撑柱的两侧外壁均固定连接有固定板。本发明通过设置有支撑环、真空泵和气孔,进行新能源汽车支撑顶起时,调节液压杆带动支撑环与新能源汽车的底部接触,继而通过真空泵将支撑环和汽车底部连接点的空气通过气孔抽掉,形成负压吸附,提高连接点的紧密性,从而提高该顶起装置的安全性能。
