A battery pack box body with high-strength guard plate for automobile

Abstract

The invention relates to the technical field of automobile batteries, in particular to a battery pack box with high-strength guard plates for cars, which includes a box with a rectangular structure, several guard plates and circulation components. The sides are provided with rectangular tooth-shaped docking grooves. The circulation assembly includes a circulation pipe, a water storage box and a water pump. The circulation pipe surrounds the box and fits in all the receiving grooves. The water storage box is connected, the other end of the circulation pipe is connected with the output end of the water pump, and the input end of the water pump is connected with the water storage box. The components and the frame inside the box improve the heat dissipation efficiency of the box. The MCU controller of the battery pack is installed on the inside of the switch cover, and the switch cover can be opened at any time for maintenance of the battery pack, which improves the maintenance efficiency. The contact area between the bottom of the body and the air.

Description

technical field [0001] The invention relates to the technical field of automobile batteries, in particular to a battery pack box with high-strength guard plates for automobiles. Background technique [0002] The existing car battery pack is composed of several batteries and boxes. The existing battery pack box is an empty box structure, which has poor compression resistance and is easy to be squeezed and deformed. Then the batteries are arranged in the box. The space is small, the heat dissipation efficiency is poor, and there are potential safety hazards. When the battery fault is repaired in the existing battery pack box, it needs to be completely opened to repair the box. There are many maintenance steps and low maintenance efficiency. [0003] In order to solve the above problems, a power battery pack box structure with a Chinese patent application number of CN201922406109.6 is disclosed. This solution has the following disadvantages: the liquid cooling plate is located ...

Problems solved by technology

[0002] The existing car battery pack is composed of several batteries and boxes. The existing battery pack box is an empty box structure, which has poor compression resistance and is easy to be squeezed and deformed. Then the batteries are arranged in the box. The space is small, the heat dissipation efficiency is poor, and there are potential safety hazards. When the existing battery pack box is overhauled for battery failure, it needs to be completely opened to overhaul the box. There are many maintenance steps and low maintenance efficiency.

[0003] In order to solve the above problems, a power battery pack box structure with a Chinese patent application number of CN201922406109.6 is disclosed. This solution has the following disadvantages: the liquid cooling plate is located at the bottom of the aluminum box and serves as the bottom plate of the box, and the cost is relatively high. The structure is relatively complicated. The setting of the pits and grooves on the stamping convex shell, although the outer surface of the flow channel becomes larger, and the setting of the pits and grooves on the stamping convex shell is equivalent to the rib structure, but it has a great impact on the heat dissipation efficiency and the box body. The strength has not improved much, and the steps for the maintenance of the box are very cumbersome
