Design structure of battery box for electromobile

Abstract

The invention provides a design structure of a battery box for an electromobile. The design structure comprises a battery box and a fixing bracket which are integrally made, wherein a power wire, a collection wire and battery modules of a power battery are arranged inside the battery box; wires between battery modules are connected together by using annealed copper sheets; a manual repairing switch of the battery box is arranged in the middle of a high voltage loop of the battery; the fixing bracket comprises two side coamings and a front coaming; pulley installing surfaces are formed at the bottoms of the side coamings; pulley blocks are fixedly installed on the pulley installing surfaces; turnups at the two sides of a box body plate of the battery box are fixedly connected with the side coamings of the fixing bracket; the front and back of a cover plate of the battery box turn downwards; pulley guide tracks are fixedly installed on box body walls at the two sides of the battery box; and the pulley guide tracks are matched with the pulley blocks so as to fix the battery box inside the fixing bracket. The design structure has the advantages of being simple and reliable in overall structure, light in weight, high in dustproof and waterproof grade, and good in ventilation and heat radiation, and is capable of being rapidly mounted and dismounted.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to the design structure of a battery box for an electric automobile. Background technique [0002] Pure electric vehicles use power battery packs as the power source of the vehicle. The power battery pack is bulky and heavy, and requires a certain amount of space and a certain strength of the installation structure to be installed on the vehicle. At present, the battery packs of pure electric vehicles are mainly divided into box type and integrated type, and the main layout positions are the chassis, under the seat or the trunk. The sub-box type can make full use of the spare space of the vehicle for layout, but the installation structure and wiring harness layout are complicated and diverse, which increases the cost of the vehicle. The integrated battery pack can optimize the installation structure, reduce the wiring harness, and save costs, but it requires a large layout ...

AI Technical Summary

Problems solved by technology

[0004] Due to the lack of layout space of existing electric vehicles, most of the battery box designs divide the battery box into multiple boxes, which is not conducive to the lightweight design of the battery box, and is not conducive to reducing the number of high and low voltage wiring harnesses of the battery box, thus increasing the battery box design. Manufacturing cost increases vehicle safety risk

The battery box installed in the pure electric mini-car has great safety hazards, especially the dustproof and waterproof level of the battery box and the ventilation and heat dissipation cannot be satisfied at the same time, and there are fatal flaws in the low insulation safety level and low fixing strength. There are disadvantages such as inconvenient replacement, installation and maintenance

If these factors cannot be effectively resolved in the process of designing the battery box, it will seriously limit the use of the battery box in electric vehicles
