The invention discloses a lifting device for a front cabin cover of an automobile. The ejector rod can extend out of the shell from the opening, and the ejector rod is provided with a first preset position and a second preset position; the elastic driving part can accumulate elastic potential energy and drive the ejector rod to move when the elastic potential energy is released, so that the ejector rod is kept at a first preset position; the locking piece can lock the ejector rod located at the second preset position so that the ejector rod can be kept at the second preset position. And the unlocking part can unlock the locking piece, so that the locking piece releases the ejector rod. According to the automobile front hatch cover lifting device, the elastic driving part replaces a gunpowder type trigger to serve as an executing mechanism of the ejector rod, and the elastic driving part can release accumulated elastic potential energy to drive the ejector rod to conduct lifting action; and meanwhile, through cooperation of the unlocking part and the locking piece, the elastic driving part can recover the state of accumulating the elastic potential energy again, so that repeated lifting actions can be completed, and repeated lifting is achieved.

    本发明公开了汽车前舱盖举升装置,包括:壳体;顶杆,顶杆能够自开口伸出壳体,顶杆具有第一预定位置和第二预定位置;弹性驱动部,弹性驱动部能够积蓄弹性势能,并在释放弹性势能时驱动顶杆移动,以使顶杆保持于第一预定位置;锁定件,能够锁定位于第二预定位置的顶杆,以使顶杆保持于第二预定位置;解锁部,能够解锁锁定件,以使锁定件释放顶杆。本发明中的汽车前舱盖举升装置,将弹性驱动部替代火药式触发器作为顶杆的执行机构,弹性驱动部能够释放积蓄的弹性势能以驱动顶杆进行举升动作,同时利用解锁部以及锁定件的配合使得弹性驱动部能够再次恢复积蓄弹性势能的状态,从而能够完成重复的举升动作,实现多次举升。
