Battery compartment lifting device

Abstract

The invention provides a battery compartment lifting device. The battery compartment lifting device comprises a battery compartment body. The battery compartment body comprises a battery compartment frame. The battery compartment frame is movably connected with an automobile body through guide posts with the upper ends fixedly connected with the automobile body, and the left side and the right side of the battery compartment frame are each provided with a lifting mechanism with the upper end fixedly connected with the automobile body and the lower end fixedly connected with the battery compartment frame, wherein the lifting mechanisms drive the battery compartment body to vertically move. The lifting mechanisms are electric lifting mechanisms. Each lifting mechanism comprises a drive screw, a front moving block, a rear moving block, a motor in transmission connection with the drive screw, an upper fixed block, a lower fixed block, two upper arms and two lower arms, wherein the upper arms are hinged to the upper fixed block and the front moving block or the rear moving block, the lower arms are hinged to the lower fixed block and the front moving block or the rear moving block, and a rhombic structure is formed by the two upper arms and the two lower arms. The battery compartment lifting device has the advantages that a traditional method for connecting the battery compartment body with the automobile body is changed, the height of the battery compartment body is reduced, the difficulty for replacing a storage battery is lowered, the replacement speed of the storage battery can be increased, and the use experience of an electric automobile can be improved.

Description

technical field [0001] The invention relates to a battery compartment device for an electric vehicle, in particular to a battery compartment lifting device. Background technique [0002] The existing storage battery used to drive the electric vehicle is usually installed in the battery compartment at the lower part of the electric vehicle body. The frame of the battery compartment is fixedly connected with the vehicle body. The frame of the battery compartment cannot move up and down. Battery quick change mechanism for battery replacement. The battery compartment is arranged at the lower part of the electric vehicle body, which is conducive to reducing the height of the center of gravity of the electric vehicle and improving the driving stability of the vehicle. But fixing the battery compartment frame provided with the battery quick-changing mechanism on the bottom of the electric vehicle body, the moving channel of the battery is easily affected by the vehicle body when c...

AI Technical Summary

Problems solved by technology

However, if the battery compartment frame equipped with a battery quick-change mechanism is fixed on the lower part of the electric vehicle body, the moving channel of the battery is easily affected by the vehicle body when replacing the battery, which increases the difficulty of quickly replacing the battery.
