Two-layer module bracket and battery pack

Abstract

The invention relates to a two-layer module bracket and a battery pack. The two-layer module bracket is mounted in a battery box body. and comprises a tray and a bracket; the tray is integrally moulded by adopting an aluminium profile moulding process and is internally hollowed; the lower end of the bracket is fixed to the interior of the battery box body; the upper end of the bracket is fixedly connected with the bottom of the tray; a mounting space used for mounting battery modules is formed between the tray and the inner wall of the battery box body. The invention provides the module bracket which is simple in structure and process moulding, and is fixed seamlessly; the overall module bracket is light in weight, low in mould cost, simple in processing moulding process, and high in structural strength; the overall production process does not have a welding process, can reduce pollution to the environment in production and shortens production time; a good module bracket can be formedby simply cutting a semi-moulded piece; moreover, the tray is internally hollowed and is light and convenient, so that physical consumption of an operator can be reduced, and the production efficiencyis improved.

Description

technical field [0001] The invention relates to the technical field of new energy, in particular to a two-layer module bracket and a battery pack. Background technique [0002] At present, new energy vehicles are developing rapidly in my country.

Problems solved by technology

[0002] At present, new energy vehicles are developing rapidly in my country. In response to the national new energy vehicle "curve overtaking" instructions, new energy vehicles are developing rapidly. Major car manufacturers have worked hard on the assembly efficiency of battery packs. The production efficiency of new energy vehicle power battery systems Improvement determines the level of its production efficiency. At present, most of them use the traditional stamping process, the efficiency of installation and production is low, and the mold cost is high.

[0003] At present, sheet metal stamping and welding forming processes are mostly used in power battery systems. In the design and manufacturing process, in addition to the deformation caused by uneven stamping materials, the deformation caused by welding also needs to be considered. The processing is cumbersome, the production cost is high, and the product size is controlled. It is difficult and the product quality is heavy, which affects product performance. This process has seriously restricted the development of power battery systems
