[0001] The utility model relates to the technical field of batteries, and in particular to a damage-resistant battery pack cooling mechanism. Background Art

[0002] A battery pack is a large-capacity battery group composed of multiple batteries. It is the core power source of electric vehicles. The battery pack will heat up during use and a cooling mechanism is required to cool it down.

[0003] The existing cooling mechanism uses liquid cooling tubes for cooling, but the liquid cooling tubes lack a protection mechanism, which causes the liquid cooling tubes to be easily damaged during the use or collision of the battery pack, resulting in leakage problems, affecting the safety of the battery pack. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the liquid cooling tube lacks a protection mechanism in the prior art, which causes the liquid cooling tube to be easily damaged, and to propose a damage-resistant battery pack cooling mechanism.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A damage-resistant battery pack cooling mechanism comprises a shell and a battery pack body, wherein the top of the shell is rotatably connected to a top cover, the bottom inner wall of the shell is fixedly connected to a plurality of support plates, liquid cooling tubes are inserted between the plurality of support plates, both ends of the liquid cooling tubes pass through the shell and are on the outside of the shell, the bottom inner wall of the shell is fixedly connected to a protective cover and covers the liquid cooling tube, the inner side of the protective cover is provided with a plurality of through holes, the battery pack body is arranged in the shell, and the liquid cooling tubes are arranged around the battery pack body.

[0007] Furthermore, a buffer pad is fixedly connected to the inner side of the top cover.

[0008] Furthermore, a lock buckle is fixedly connected to an outer wall of one side of the shell.

[0009] Furthermore, a plurality of limit blocks are fixedly connected to the bottom inner wall of the shell, and the limit blocks are arranged on the inner side of the liquid cooling tube.

[0010] The beneficial effects of the utility model are:

[0011] 1. Protect the liquid cooling pipe with a protective cover to avoid damage to the liquid cooling pipe and avoid leakage.

[0012] 2. The flow of liquid in the liquid cooling tube takes away the temperature generated by the battery pack body during operation, thereby cooling the battery pack body to ensure the operation of the battery pack.

[0013] 3. By putting the top cover on the shell and locking the top cover with the lock, the battery pack body and the liquid cooling pipe can be better protected, thereby improving the protection effect. BRIEF DESCRIPTION OF THE DRAWINGS
