[0024] Example 2

[0025] A kind of battery pack underpinning vibration tooling, mainly through tooling reproduces the vibration that the bump, road surface impact (such as stone road, deceleration zone) such as encountered in vehicle driving, verifies the performance of battery pack under long-term mechanical stress, this embodiment aims at realizing the stable limit of different size battery pack.

[0026] As Figs. 1-3 Shown in a kind of battery pack underpinning vibration tooling, including bottom plate 1, bottom plate 1 is used to install limiting component and the battery pack of limiting component stable limit, the bottom plate 1 of installing battery pack can be vibrated, and battery pack is vibrated and detected.The top front side of bottom plate 1 is symmetrically equipped with first fixed frame 2, and first fixed frame 2 is symmetrically arranged left and right, and first fixed frame 2 rear side is equipped with first positioning block 3, while the top right side of bottom plate 1 is equipped with second fixed frame 4, and second fixed frame 4 left side is equipped with second positioning block 5, i.e.first positioning block 3 and second positioning block 5 can realize the positioning of both sides of battery pack.

[0027] In addition, the top left rear diagonal of bottom plate 1 is equipped with third fixed frame 6, and the top left and right of third fixed frame 6 is symmetrically equipped with fourth fixed frame 7, and fourth fixed frame 7 is slidably connected with mounting plate 8, i.e.mounting plate 8 can move forward and backward on fourth fixed frame 7, and mounting plate 8 is rotatably connected with mounting frame 10 through mounting block 9, it can be understood that mounting frame 10 can be horizontally rotated left and right on mounting block 9;The front side of mounting frame 10 is symmetrically equipped with third positioning block 11.

[0028] The first positioning block 3, the second positioning block 5 and the third positioning block 11 are plastic blocks arranged to rotate around the shaft, and can rotate vertically. The first positioning block 3, the second positioning block 5 and the third positioning block 11 are narrow and small at the top and bottom, and wide in the middle. The middle part is hollow. The battery pack can be initially placed in contact with the first positioning block 3 and the second positioning block 5, i.e. at the angle between the first positioning block 3 and the second positioning block 5. At this time, the first positioning block 3, the second positioning block 5 and the third positioning block 11 are only in contact with each other. Then the mounting plate 8 is driven to move inward, thereby driving the third positioning block 11 on the mounting frame 10 to contact the other corner of the battery pack, i.e. the third positioning block 11 clamps the other corner of the battery pack. The mounting plate 8 continues to move inward, and the mounting frame 10 is appropriately rotated according to the different states of the battery pack, so that the third positioning block 11 completely fits the corner of the battery pack.
