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.
