A vehicle tray assembly for installing a power battery and a vehicle

Abstract

The invention provides a vehicle tray assembly for installing a power battery. The vehicle tray assembly comprises a tray bottom plate and an installation cross beam, wherein the installation cross beam is arranged around the tray bottom plate, the tray bottom plate comprises at least one sub bottom plate, the sub bottom plate comprises an upper plate, a lower plate and a buffer cavity, the buffer cavity is arranged between the upper plate and the lower plate, and cooling fins are arranged at a lower surface of the tray bottom plate. In the vehicle tray assembly for installing the power battery, provided by the invention, the buffer cavity can have a good buffer effect during the travelling process of the automobile and when collision occurs, the influence of collision on the power battery is reduced, and the application safety of the power battery is improved; meanwhile, a runner or other assemblies also can be arranged in the buffer cavity, the safety performance is improved, and the space is also saved to a certain extent; and moreover, due to the arrangement of the cooling fins, heat transferred from the tray bottom plate can be dissipated very well by an air-cooling mode during the travelling process of the automobile.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a vehicle tray assembly for installing a power battery. Background technique [0002] With the continuous development of new energy vehicles, the requirements for the installation and safety performance of power batteries in new energy vehicles are becoming higher and higher; especially how to install power batteries on vehicles while taking into account the use of power batteries The safety performance in the process and the response to some special problems are a difficult problem hindering the development of new energy vehicles. [0003] In new energy vehicles, the current general practice is to install the power battery (module or module) on the car tray; it not only saves space, but also concentrates the weight of the power battery on the bottom of the car, improving the stability of the car At the same time, through the exposed characteristics of the bottom of the tray, the natur...

AI Technical Summary

Problems solved by technology

During the use of the car, since the pallet bottom plate 10 is generally arranged at the bottom of the car, it is similar to the role of the car chassis; in the process of driving, it is inevitable to collide; while the conventional steel pallet is a single-layer structure, when it is hit When there is no buffer function, it is easy to damage the battery, cause the battery to run out of heat or even catch fire, threatening the safety of the driver

In addition, the strength and rigidity of conventional steel trays are insufficient, and it is difficult to meet the long-term vibration requirements for installation on automobiles

Moreover, the heavy weight of the steel pallet is not conducive to the lightweight requirements of new energy vehicles

Moreover, due to the limitation of the material of the steel tray and its own strength, in the process of making the steel tray, the edge needs to be designed with a beveled edge, which not only takes up a lot of space, but also is not conducive to the placement of the internal power battery
