In order to better tightly fix the anti-collision beam of the battery pack on the fixing bracket, at least one fixing block is respectively arranged on the symmetrical positions of the second fixing plates of the two fixing brackets facing away from each other. The shape, size and position can be adjusted according to the space between the anti-collision beam and the fixing bracket after they contact each other, so as to achieve the effect of close contact and fixing.

In order to prevent the battery pack from falling during the vibration process and damage the components on the battery pack, at least one front support component is provided on the front bottom plate of the base, and at least one rear support component is provided on the rear bottom plate, and the front support component and The rear supporting parts are all stepped structures.

In order to avoid the suspension of the base and the vibrating table surface and increase the contact area between the base and the vibrating table surface, several support pads are provided on the bottom of the front bottom plate and the rear bottom plate of the base.

The vehicle power battery pack vibrating support of the utility model has simple structure and convenient operation. The enclosure can prevent the battery pack from moving forward and backward, and can prevent the battery pack from turning over and falling on the vibrating table to damage the components of the battery pack. The front and rear bottom plates of the base A number of support pads are set on the top to prevent the base and the vibrating table from being suspended in the air, and strengthen the stability of the entire vehicle power battery pack vibrating support. The vehicle power battery pack vibration support of the utility model has high strength and rigidity, is safe and reliable, and can better meet the requirements of the power battery pack vibration test.
