In the embodiment, the battery module 200 can be taken as an example of an air-cooled battery module.

[0038] The vibration tool 100 includes a vibration table 110, a front end fixing assembly 120, a rear end fixing assembly 130, and two side end fixing assemblies 140.

[0039] The rear end fixing assembly 130 is used to fix the rear end 220 of the battery module 200 to the vibration table 110.

[0040] The two side end fixing assemblies 140 are located close to the front end 210 of the battery module 200, and are respectively used to fix the two side ends 230 of the battery module 200 to the vibration table 110.

[0041] The front end fixing assembly 120 is used to connect the front end 210 of the battery module 200 to the side end fixing assemblies 140, so as to fix the front end 210 of the battery module 200 to the vibration table 110.

[0042] Specifically, when the battery module 200 without a cover is subjected to a vibration test, the front end 210, the rear end 220, and the two side ends 230 of the battery module 200 are fixed to the vibration table through the front end fixing assembly 120, the rear end fixing assembly 130, and the two side end fixing assemblies 140, respectively, and then the battery module 200 without a cover is subjected to a vibration test.

[0043] The vibration tool for the battery module without a cover in the embodiment of the present disclosure can fix the battery module to the vibration table through the front end fixing assembly, the rear end fixing assembly, and the two side end fixing assemblies, respectively, so as to control the degrees of freedom of the battery module in each direction, and thus ensure that the battery module without a cover can smoothly pass the vibration test of the battery module.

[0044] As shown, Figure 2 As shown, the rear end 220 of the battery module 200 has a first flange structure 221.

[0045] The rear end fixing assembly 130 includes a first pressing block 131 and a plurality of first fasteners 132.

[0046] As shown, Figure 3 As shown, the first pressing block 131 is provided with a first groove 133 at the edge area of the side facing the vibration table 110, and the first groove 133 matches the first flange structure 221. Specifically, in the embodiment, the first groove 133 is in a stepped shape.

[0047] The first pressing block 131 is provided with a plurality of first fixing holes 134 at intervals along the length direction of the first pressing block 131, and the vibration table 110 is provided with a plurality of second fixing holes corresponding to the first fixing holes 134.

[0048] The first recess 133 is clamped on the first flange structure 221, and the first fastener 132 sequentially passes through the first fixing hole 134 and the second fixing hole corresponding thereto, so as to fix the rear end 220 of the battery module 200 to the vibration table 110, thereby limiting the movement of the rear end 220 of the battery module 200 in the X-axis, Y-axis and Z-axis directions.

[0049] It should be noted that in the present embodiment, the first fastener 132 can adopt a fastening bolt.
