Example Embodiment

[0043] Example 1

[0044] Such as Figure 1-Figure 9 As shown, a tailor-welded aluminum alloy module tray of this embodiment includes a first tray 100. The first tray 100 includes two first fixed beams 101 and a plurality of first cross beams 102. A fixed beam 101 is arranged in parallel and connected to the battery box 300 respectively, and two ends of the first cross beam 102 are welded to the two first fixed beams 101 respectively. By adopting the tailor-welded method of several first beams and the first fixed beams, the first tray can be easily adjusted according to actual needs by adjusting the number of the first beams or adjusting the gap between the first beams or adjusting the length of the first beams. To meet the needs of different projects, it is more widely used. At the same time, the first beams are not continuous, but independent of each other. There is a gap between the first beams, which can reduce the weight of a part of the first tray and increase the energy d...

Example Embodiment

[0052] Example 2

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

[0054] Such as Figure 1-Figure 9 As shown, in this embodiment, the second tray 200 includes two second fixed beams 201 and a number of second cross beams 202. The two second fixed beams 201 are arranged in parallel and are respectively connected to the battery box 300 The two ends of the second cross beam 202 are respectively welded to the two second fixed beams 201. By adopting the tailor-welded method of several second beams and second fixed beams, the second tray can be easily adjusted according to actual needs by adjusting the number of second beams or adjusting the gap between the second beams or adjusting the length of the second beams. To meet the needs of different projects, it is more widely used. At the same time,...

Example Embodiment

[0065] Example 3

[0066] Such as Picture 10 As shown, a battery pack of this embodiment includes a battery box 300, a battery module 400, and the module tray. The module tray is installed in the battery box 300, and the battery module 400 are respectively installed on the bottom beam of the battery box and the module tray. The battery box 300 is provided with a column 301, and the first connecting plate 108 on the first tray 100 or the second connecting plate 208 on the second tray 200 of this embodiment passes through the first mounting hole 109 or the second mounting hole 109 or the second mounting hole respectively. 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. The two-layer module tray plays a role in supporting the two-layer battery module or other devices in the battery pack in the enti...

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...
