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.
