The invention provides a jacking device, a vehicle front cover assembly and a vehicle, and the jacking device comprises a shell which forms a cavity; the jacking piece is arranged in the cavity; the adjusting structure is arranged in the cavity and connected with the jacking piece, and the adjusting structure is in heat conduction contact with the shell; the gas generator is arranged in the cavity; when the gas generator pushes the jacking piece to move, the adjusting structure provides resistance positively correlated with the temperature. In the embodiment of the invention, the performance fluctuation of the gas generator caused by the temperature influence can be reduced or eliminated by the resistance provided by the adjusting structure, so that the performance reliability of the jacking device can be improved.

    本申请提供了一种顶升器、车辆前盖组件和车辆,其中,顶升器包括:壳体,所述壳体形成一空腔;顶升件,设置于所述空腔内;调节结构,设置于所述空腔内且与所述顶升件连接,所述调节结构与所述壳体热传导接触;气体发生器,设置于所述空腔内;其中,所述气体发生器推动所述顶升件移动时,所述调节结构提供与温度正相关的阻力。本申请实施例中,气体发生器受温度影响而产生的性能波动能够被调节结构提供的阻力减轻或消除,从而能够提高顶升器的性能可靠性。
