Abstract: A vehicle power supply device is provided. The vehicle power supply device includes: a fixed base; a scissor-fork lifting mechanism, where the scissor-fork lifting mechanism is mounted on the fixed base; a power supply head, where the power supply head is mounted on the scissor-fork lifting mechanism and is driven by the scissor-fork lifting mechanism to ascend or descend; and a drive device, where the drive device includes a drive unit and a transmission unit configured to convert rotational movement into linear movement. The drive unit and the transmission unit are stacked along a lifting direction of the scissor-fork lifting mechanism. The drive unit is connected with the scissor-fork lifting mechanism by the transmission unit to drive the scissor-fork lifting mechanism to ascend or descend.

Abstract: A vehicle power supply device is provided. The vehicle power supply device includes: a fixed base; a scissor-fork lifting mechanism, where the scissor-fork lifting mechanism is configured to be driven by a drive device to ascend or descend; and the scissor-fork lifting mechanism includes at least one scissor-fork swing rod set, the scissor-fork swing rod set includes at least one pair of swing rods, each pair of swing rods includes two swing rods that are cross-arranged and are hinged with each other, and two swing rods in a pair of swing rods that is closest to the fixed base are separately mounted on the fixed base; and a power supply head, where the power supply head is mounted on two swing rods in a pair of swing rods that is farthest from the fixed base, and the power supply head is driven by the scissor-fork lifting mechanism to ascend or descend.
