Technical Field

[0001] The utility model belongs to the technical field of energy storage PACK boxes and relates to an energy storage PACK box which is convenient for fixing a battery pack. Background Art

[0002] Battery PACK is widely used in new energy electric vehicles. The battery PACK system of electric vehicles uses a mechanical structure to connect many single cells in series, and is connected to the microcontroller of the electric vehicle through the battery management system and communication frame of the battery PACK. In order not to occupy precious space in the car, more and more power battery PACKs are installed in the PACK box, which can effectively protect the power battery.

[0003] When installing batteries in traditional energy storage PACK boxes, operators are required to use fixing bars and screws to fix the batteries to prevent the batteries from shaking when the PACK moves and to improve the connection stability. However, there are a large number of fixing bars and screws, which makes installation time-consuming and laborious, and the assembly efficiency is low.

[0004] Based on this, we designed an energy storage PACK box that is easy to fix the battery pack. Utility Model Content

At this time, the support block provides support for the battery, and then the cover body is covered and the fixing bolts are tightened. Under the action of the fixing bolts, the connecting piece will drive the lifting plate to lift upward. At this time, the vertical rod will be inserted into the gap between the grid plate and the battery to fix the battery. The operation is convenient and the assembly efficiency is further improved.

[0012] The front and rear sides of the box body and the inner guard plate are respectively provided with an air outlet and an air inlet, a heat dissipation fan is fixed on the inner side of the box body, and the heat dissipation fan is aligned with the air outlet.

Moreover, under the action of the grid plate, there is a certain gap between each battery, further improving the heat dissipation effect.

[0014] A gasket is arranged inside the cover body, and the gasket and the supporting block are made of high temperature resistant rubber material.

[0015] With the above structure, in the assembled energy storage PACK box, the top of the battery abuts against the gasket, which can prevent short circuits between the batteries. In addition, the gasket and the support block can provide buffering when the battery is vibrated, thereby improving the protection effect on the battery.

[0016] Compared with the prior art, the energy storage PACK box for fixing the battery pack has the following advantages:

[0017] 1. After assembling the batteries, all batteries can be fixed by fixing the cover body through the box body, inner guard plate, grille plate, lifting plate, vertical rod and lifting mechanism. No additional fixing strips and screws are needed to fix the batteries. The operation is more convenient and can effectively improve the assembly efficiency of the energy storage PACK box.

[0018] 2. Through the connecting plate, when the box is deformed by external impact, the connecting plate can deform to absorb the impact force and provide protection for the battery inside the inner guard plate.

[0019] 3. Through the cooling fan and grille plate, there is a certain gap between each battery, so that the hot air inside the box is exchanged with the outside air, improving the heat dissipation effect of the battery. BRIEF DESCRIPTION OF THE DRAWINGS
