Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of battery replacing device, especially relates to a power battery dismounting tool. BACKGROUND

[0002] With the continuous development of new energy vehicle technology, the market demand for electric buses is gradually increasing. As the core component of electric buses, the performance and reliability of power batteries directly affect the driving range and service life of the vehicle. In order to solve the space limitation problem in the process of battery replacement and maintenance, more and more electric buses adopt power battery modular design, which not only facilitates battery management, but also effectively prolongs the service life of the whole vehicle. However, the dismounting problem of power battery modules, especially for the battery modules arranged under the vehicle chassis, still faces technical challenges.

[0003] At present, most of the power batteries of electric buses are installed under the chassis or on the top of the vehicle body. The battery module usually has a large volume and weight, especially the battery module under the chassis, which needs to be extracted from the side compartment during replacement. The dismounting and mounting operation of such battery module needs to be carried out in a limited space, and the traditional operation mode often faces many difficulties. Especially when using a forklift for dismounting, due to the limited height and depth of the forklift arm, the forklift arm cannot be deeply inserted into the bottom of the battery module, making the dismounting operation of the battery module complicated and inconvenient.

[0004] Specifically, when the forklift dismounts the battery module, the depth of the forklift arm limits the extraction depth of the battery module, which cannot accurately take out or install the battery module from or to the battery compartment. Even if the forklift arm can be deeply inserted into the bottom of the battery module, after lifting the forklift arm, the opening of the battery compartment door may not be sufficient, which cannot smoothly extract or place the battery module to a new position. This problem seriously affects the replacement efficiency and safety of the operation of the battery module, especially in the case of frequent battery replacement and strict time requirement, which often leads to low production and maintenance efficiency.

[0005] Most of the battery dismounting tools on the market do not effectively solve this problem. The existing dismounting equipment generally uses manual or mechanical methods to extract or install the battery module, which usually cannot provide sufficient stability and safety in the case of limited space and heavy load. In addition, the operation of the traditional tool is complicated and needs more manual participation, which is easy to cause unnecessary safety hazards. Therefore, there is an urgent need for a tool that can efficiently, safely and conveniently complete the dismounting of the battery module in the case of narrow battery compartment space and inconvenient forklift operation.
