The invention provides a jacking device and a vehicle comprising the jacking device, the jacking device comprises a sleeve, a piston rod, a gas generator and a sealing cap, the piston rod is arranged in the sleeve in the axial direction of the sleeve, a through hole is formed in the top end of the sleeve, the sealing cap is fixed to the top end of the sleeve to seal the through hole, the gas generator is arranged in the bottom end of the sleeve, and the gas generator is arranged in the bottom end of the sleeve. The gas generator is used for ejecting the piston rod outwards from the through hole; the piston rod is sleeved with a guide part close to the through hole and a spring away from the through hole, the top end of the guide part is provided with a first annular boss extending outwards in the radial direction, the bottom end of the guide part is provided with a second annular boss extending outwards in the radial direction, and the first annular boss is provided with a pressure relief opening; when the piston rod is ejected outwards, the spring extrudes and cracks the second annular boss and then moves to abut against the first annular boss. According to the invention, rapid pressure relief of gas in the casing pipe after the jacking device is actuated can be realized.
本发明提供一种顶升器以及包括该顶升器的车辆,所述顶升器包括套管、活塞杆、气体发生器和密封帽,活塞杆沿套管的轴向设置于套管内,套管的顶端设有通孔并且固定有密封帽以对通孔进行密封,套管的底端内部设有气体发生器,气体发生器用于使活塞杆自通孔向外顶出;活塞杆上套设有邻近通孔的导向件以及远离通孔的弹簧,导向件的顶端设有径向向外延伸的第一环状凸台,导向件的底端设有径向向外延伸的第二环状凸台,且第一环状凸台上设有泄压开口;当活塞杆向外顶出时,弹簧将第二环状凸台挤压破裂后运动至与第一环状凸台抵接。本发明能够实现顶升器致动后套管内气体的快速泄压。
