[0034] New energy technologies have begun to rise in recent years, and more and more related industries have emerged, and a steady stream of people have begun to engage in the new energy industry. The main characteristics of new energy are energy saving and green. Especially for electric vehicles, the battery pack is the heart of the entire energy source, and the design requirements for the battery pack are getting higher and higher. Not only does it require an increase in energy density, but safety is also crucial. Therefore, before the battery pack is installed on the vehicle, many experiments are required to verify the safety of the battery pack. Usually, various air tightness, vibration, impact, charging and discharging, falling, flipping, collision, extrusion and other experiments are carried out on the battery pack to verify the reliability of the battery pack. However, most of the current battery pack vibration tooling may interfere with the battery pack hoist tooling, and the installation steps are cumbersome.

[0035] Based on this, see Figure 1 The battery pack vibration tool 1000 provided in the embodiment of the utility model can effectively improve the above-mentioned technical problems.

The plurality of first support columns 200 and the plurality of second support columns 300 are respectively arranged on both sides of the symmetry axis of the base plate 100; the plurality of first support columns 200 are arranged at intervals along the length direction of the base plate 100; the plurality of first support columns 200 and the plurality of second support columns 300 are arranged one by one. That is, the first support columns 200 and the corresponding second support columns 300 are symmetrically arranged along the symmetry axis of the base plate 100. One end of the crossbeam 400 is detachably connected to the first support column 200 at the edge, and the other end of the crossbeam 400 is detachably connected to the corresponding second support column 300; the plurality of first support columns 200, the plurality of second support columns 300 and the crossbeam 400 are used together to fix and place the battery pack that needs to undergo a vibration test.

[0037] The battery pack can be fixed in position by setting a plurality of first support columns 200 and a plurality of second support columns 300. By setting a detachably connected crossbeam 400, the battery pack can be first hoisted onto the bottom plate 100 and fixed in position with the support columns, and then the crossbeam 400 can be installed after the hoisting tooling is removed, so that the support columns and the crossbeam 400 can fix the entire battery pack together, thereby avoiding interference between the hoisting rope of the hoisting tooling and the vibration tooling. In addition, the design has a simple structure and is easy to install, which simplifies the installation process of the battery pack vibration detection and shortens the installation time.
