The invention relates to the technical field of accessories for vehicles and discloses an emergency jacking device for a vehicle. The emergency jacking device comprises a supporting seat. The supporting seat comprises a front half seat and a back half seat that are arranged symmetrically. Two ends and middle parts of the opposite surfaces of the front and back half seats are connected through adjustable telescopic rods, supporting plates are fixedly connected to two sides of the tops of the front and back half seats, threaded rods penetrate through the side surfaces of the supporting plates and are movably connected to the side surfaces of the supporting plates through bearings, a first thread bushing and a second thread bushing are in threaded connection to the outer surfaces of the threaded rods separately, and a first lifting rod and a second lifting rod are rotatably connected to the tops of the first and second thread bushings separately. By amplifying the area of the supporting seat, when the emergency jacking device is used on a soft pavement, the depth of being sunken into soil is reduced and the vehicle lifting stability is improved as the contact area with the pavement isrelatively large. By rotating a rotary handle, the threaded rods drive the first and second thread bushings to move in opposite directions, so that it is convenient to lift the vehicle.

    本发明涉及车用附件技术领域,公开了一种车用应急顶升装置,包括支撑座,支撑座包括对称设置的前半座和后半座,前半座与后半座相对面的两端及中部通过可调节伸缩杆相连接,前半座与后半座顶部的两侧均固定连接有支撑板,支撑板的侧面贯穿并通过轴承活动连接有螺纹杆,螺纹杆的外表面分别螺纹连接有第一螺纹套和第二螺纹套,第一螺纹套和第二螺纹套的顶部分别转动连接有第一抬升杆和第二抬升杆。本发明采用将支撑座的面积放大,在软质路面使用时,因与路面的接触面较大,降低陷在泥土里的深度,增加了对车辆抬升的稳定性,通过转动转把使螺纹杆带动第一螺纹套和第二螺纹套相向移动,方便了对车辆的抬升。
