Problems solved by technology

[0003] The two-layer tray of the traditional power battery pack is mostly made of sheet metal tailor welding. It is made by manual laser blanking and bending by a bending machine. The product consistency is low, the surface is not smooth enough, the production efficiency is low, and it is not conducive to mass production.
In addition, the second-layer tray of the traditional power battery pack is heavy due to the sheet metal tailor welding method. With the increase in energy density requirements, it is difficult to meet customer requirements

Embodiment 1

[0044] Such as Figure 1-Figure 9 As shown, a tailor-welded aluminum alloy module tray in this embodiment includes a first tray 100, and the first tray 100 includes two first fixed beams 101 and several first beams 102, and the two first A fixed beam 101 is arranged in parallel and is respectively connected to the battery box 300 . Both ends of the first beam 102 are respectively welded to the two first fixed beams 101 . The first pallet can be conveniently adjusted according to actual needs by adjusting the number of first beams or adjusting the gap between the first beams or adjusting the length of the first beams by tailor-welding several first beams and the first fixed beam In order to meet the needs of different projects, the application is more extensive. At the same time, the first beams are not continuous, but independent of each other. There are gaps between the first beams, which can reduce part of the weight of the first pallet and increase the energy density. The ...

Embodiment 2

[0053] In fact, a tailor-welded aluminum alloy module tray in this embodiment includes a second tray 200. The first tray 100 and the second tray 200 in this embodiment are generally similar in structure, but the specific details are different.

[0054] Such as Figure 1-Figure 9 As shown, in this embodiment, the second tray 200 includes two second fixed beams 201 and several second beams 202, the two second fixed beams 201 are arranged in parallel and connected to the battery box 300 respectively , two ends of the second beam 202 are respectively welded to the two second fixed beams 201 . The second pallet can be conveniently adjusted according to actual needs by adjusting the number of second beams or the gap between the second beams or the length of the second beams by adjusting the number of second beams and the second fixed beam. In order to meet the needs of different projects, the application is more extensive. At the same time, the second beams are not continuous, but ...

Embodiment 3

[0066] Such as Figure 10 As shown, a battery pack in this embodiment includes a battery case 300, a battery module 400 and the module tray, the module tray is installed in the battery case 300, and the battery module 400 are installed on the bottom beam of the battery box and the module tray respectively. The battery box 300 is provided with a column 301, and the first connecting plate 108 on the first tray 100 of this embodiment or the second connecting plate 208 on the second tray 200 respectively passes through the first mounting hole 109 or the second mounting hole 109. The hole 209 is connected to the upper end of the column 301, and the lower end of the column is connected to the battery box.

[0067] In the battery pack of this embodiment, a two-layer module tray is arranged inside the battery box, and the two-layer module tray plays a role in supporting the two-layer battery module or other components in the battery pack in the entire battery pack, and can make full ...

Abstract

The invention relates to a tailor-welded type aluminum alloy module tray and a battery pack. The tailor-welded aluminum alloy module tray comprises two fixed beams and a plurality of beams; two fixedbeams are arranged in parallel and connected with a battery box body; two ends of each beam are respectively welded on two fixed beams; the fixed beams and the beams are molded through an extrusion mold by adopting aluminum alloy material and are in tailor-welded connection. The tailor-welded type aluminum alloy module tray disclosed by the invention is formed by performing the tailor-welded on the parts molded through the extrusion mold by adopting the aluminum alloy material; the mold is cheap and easy to acquire; the development cots is reduced, the production efficiency is high, the tray can be suitable for the large-scale production demand, and the economic benefit is increased.

Description

technical field [0001] The invention relates to the field of new energy technology, in particular to a tailor-welded aluminum alloy module tray and a battery pack. Background technique [0002] At present, the global automobile industry is facing the huge challenge of energy and environmental issues; pure electric vehicles with high energy utilization rate and no pollution to the environment are increasingly becoming the development direction of the future automobile industry. As the core component of a pure electric vehicle, the structural design and safety performance of the power battery pack will directly affect the overall performance of the pure electric vehicle. Since the installation space reserved for battery packs in pure electric vehicles is small and irregular in shape, in order to make full use of the limited space of battery packs, it is often necessary to arrange two-layer modules, and the design of two-layer module trays becomes particularly necessary. [00...
