Electric vehicle battery pack installation structure

Abstract

The invention aims at providing an electric vehicle battery pack installation structure for achieving fast replacing of battery packs. A battery pack of the electric vehicle battery pack installation structure comprises a front battery pack and a rear battery pack, the electric vehicle battery pack installation structure is characterized in that the front battery pack is slidably installed under a front-row chair of a vehicle through a sliding rail distributed in the length direction of a vehicle body, the rear battery pack is installed under a rear-row chair of the vehicle, and a cushion of the rear-row chair of the vehicle rotates around an axis of a fixed support shaft of the cushion of the rear-row chair of the vehicle, or the cushion of the rear-row chair of the vehicle and the fixed support shaft of the cushion of the rear-row chair of the vehicle are of a separable structure. The electric vehicle battery pack installation structure cannot influence the appearance, is convenient to process and manufacture, can achieve fast battery pack replacing, effectively improves the possibility of avoiding battery explosion and burning and other safety hazards caused by collision, does not need to be matched with a lifter, a trench and other device places and avoids the risk that water can enter the exposed battery pack and the battery pack can run into the ground.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to an installation structure of a battery pack of an electric vehicle. Background technique [0002] At present, with the improvement of people's awareness of environmental protection and the depletion of oil resources, various new energy vehicles have been developed rapidly under the control of national policies. As a representative of new energy vehicles, electric vehicles have the advantages of economy, energy saving, and environmental protection, but their short cruising range severely limits their development. Due to the limitations of the front and rear suspensions, seat beams, and interior parts, the space for battery layout is limited, and the current battery volume is relatively large, so it is difficult to increase the cruising range by increasing the number of batteries to a certain extent. Therefore, people think of setting up a quick-change batte...

AI Technical Summary

Problems solved by technology

Putting it in the front and rear compartments will cause a high load on the front axle or rear axle, resulting in uneven distribution of front and rear axle loads. If a frontal or rear collision occurs, it is likely to hit the battery pack, causing a safety hazard; The spare tire will be arranged, if the battery is placed, the position of the spare tire will be changed or canceled, which is unacceptable to many consumers

Placing it under the front and rear floor will cause problems of small distance from the ground or small indoor space. Because water is easy to enter the lower part of the vehicle body, the sealing requirements for the battery pack are higher, and the quick change is inconvenient, requiring a large quick change site and equipment. quick change possible

[0004] To sum up, the layout of traditional battery packs has the above-mentioned shortcomings and hidden dangers, and it cannot be replaced quickly
