Accommodating support shell, battery pack and vehicle

Abstract

The invention relates to the technical field of battery packs, and discloses an accommodating support shell, a battery pack and a vehicle. The accommodating support shell comprises an accommodating support shell side wall and an inner beam, the lower edge of the accommodating support shell side wall is provided with a support flanging extended inwards, one end of the inner beam is connected with the surface of the inner side of the accommodating support shell side wall, the other end of the inner beam is connected with the surface of the inner surface of the support flanging, an inner cavity is formed between the inner beam and the accommodating support shell side wall, and the inner beam comprises a transverse supporting beam portion. When assembling is performed, a battery module installation frame is located in the accommodating support shell and is lapped joint and fixed on the support flanging and the transverse supporting beam portion, when the battery pack is collided or extruded, the accommodating support shell can protect the installation frame to improve the protection and the safety, and the accommodating support shell is only needed to replace so as to reduce the latermaintenance cost, and the accommodating support shell can reduce the cost of the battery pack, can improve the safety and the replacement and can simplify the assembling flow.

Description

technical field [0001] The invention relates to the technical field of battery packs, in particular to an accommodating support case, a battery pack and a vehicle. Background technique [0002] With the improvement of people's quality of life, the penetration rate of vehicles is getting higher and higher. At the same time, with the improvement of environmental protection awareness, new energy vehicles such as hybrid vehicles and pure electric vehicles have been greatly developed. As the power source of new energy vehicles, the performance of power batteries is crucial to the cruising range and power performance of new energy vehicles. However, as a key component of electric vehicles, battery packs account for most of the cost of electric vehicles, which makes electric vehicles more expensive to purchase and maintain than traditional fuel vehicles, and is inconvenient to maintain. Therefore, reducing the cost of electric vehicles Production costs play a huge role in driving ...

However, as a key component of electric vehicles, battery packs account for most of the cost of electric vehicles, which makes electric vehicles more expensive to purchase and maintain than traditional fuel vehicles, and is inconvenient to maintain. Therefore, reducing the cost of electric vehicles Production costs play a huge role in driving electrification

[0003] At this stage, most of the power battery packs are made of aluminum profiles, the manufacturing process is complicated, and the production cost is high

For example, the lower casing of the battery pack has an integrated structure. Once the lower casing is damaged by collision or extrusion, it will directly endanger the electrical components and battery modules inside, causing safety hazards and increasing maintenance costs.
