Description

Technical Field

[0001] The utility model relates to the technical field of automobile battery repair, in particular to an automobile battery repair device. Background Art

[0002] New energy vehicles are vehicles that use new energy to replace traditional fuels, usually electric vehicles. Electric vehicles mainly rely on batteries to store electrical energy to drive the motor. The car battery is the most important component of an electric vehicle. It is generally installed at the bottom of the body of a new energy vehicle, usually located in the chassis between the front and rear axles of the vehicle to ensure the low center of gravity and good stability of the vehicle. During the use of electric vehicles, regular battery inspection and maintenance is particularly important, which can timely detect and solve battery problems, reduce damage to the battery, and extend the battery life.

[0003] The lifting platform is one of the commonly used tools in the maintenance of new energy vehicle batteries. The lifting platform can provide a stable working platform to assist in the disassembly and assembly of the battery, making it convenient for technicians to perform maintenance work on the battery pack. Existing lifting platforms generally include hydraulic lifts or scissor lifts. The top of the lifting mechanism is fixed with a lifting platform, and the bottom is equipped with walking wheels to facilitate the transfer of the battery pack.

[0004] However, the existing lifting platform still has the following shortcomings when used for new energy vehicle battery maintenance:

[0005] New energy vehicle batteries are generally battery packs installed on the chassis. The battery packs are composed of multiple neatly arranged single cells. During the inspection and maintenance of new energy vehicle batteries, the single cells need to be disassembled, repaired or replaced in most cases. The existing lifting platform transfers the disassembled battery pack to the maintenance area for maintenance. After the maintenance is completed, the chassis and battery pack need to be reset and installed on the lifting platform. During the process, the staff needs to make multiple fine adjustments to the position of the lifting platform body to align the connection and installation positions between the chassis and the vehicle, which causes inconvenience in installation.
