[0023] A lithium battery pack with a heat dissipation structure comprises an upper shell 1, a lower shell 2 and a heat dissipation fan 5. The upper shell 1 and the lower shell 2 are abutted and connected. A connecting plate 3 is fixedly connected to the upper surface of the upper shell 1. A circular groove is provided on the surface of the connecting plate 3, and a partition net 4 is fixedly connected to the inner side of the circular groove. A heat dissipation hole 6 is provided on the surface of the upper shell 1, and a connecting groove 7 is provided on the surface of the lower shell 2. A supporting spring 8 is fixedly connected to the inner side of the connecting groove 7. A card plate 9 is slidably connected to the inner side of the connecting groove 7. A push plate 10 is fixedly connected to the surface of the card plate 9. A connecting spring 11 is fixedly connected to the surface of the push plate 10. A pull ring 12 is fixedly connected to the outer surface of the card plate 9. A heat dissipation auxiliary pipe 13 and a heat dissipation main pipe 14 are provided inside the upper shell 1. Through the abutting connection between the upper shell 1 and the lower shell 2, under the connection of the connecting groove 7 and the lower shell 2, and through the sliding connection of the connecting groove 7 and the card plate 9, the position of the card plate 9 on the upper shell 1 is adjusted, so that the upper shell 1 and the lower shell 2 can be quickly connected and separated.

[0024] Furthermore, the upper shell 1 and the lower shell 2 are abutted to form an enclosed space, the connecting plate 3 is in a block shape and acts on the outer surface of the upper shell 1, and the heat dissipation fan 5 acts in the circular groove opened on the surface of the connecting plate 3. Through the connection between the upper shell 1 and the connecting plate 3, under the action of the circular groove on the surface of the connecting plate 3, the supporting effect of the partition net 4 and the heat dissipation fan 5 is achieved.

[0025] Furthermore, the partition net 4 is in a plate shape and evenly distributed in the circular groove opened on the surface of the connecting plate 3. The partition net 4 acts on the top of the heat dissipation fan 5 through the connecting plate 3. The heat dissipation holes 6 are evenly distributed on the surface of the upper shell 1. The partition net 4 prevents debris from entering the circular groove and causing damage to the heat dissipation fan 5.

[0026] Furthermore, the cross-section of the connecting groove 7 is in a "T" shape, and the two ends of the support spring 8 are fixedly connected to the inner side of the connecting groove 7 and the surface of the clamping plate 9. Through the connection between the connecting groove 7 and the lower shell 2, under the action of the support spring 8, the clamping plate 9 can slide elastically in the connecting groove 7, thereby realizing the adjustment of the position of the clamping plate 9 on the lower shell 2.

[0027] Furthermore, the push plates 10 are connected to the inner side of the card plate 9 in two groups. The push plates 10 are connected to the upper shell 1 through the card plate 9. Through the connection between the card plate 9 and the push plates 10, under the action of the push plates 10, the card plate 9 achieves a pressing and supporting effect on the position of the upper shell 1 on the lower shell 2.

[0028] Furthermore, both ends of the connecting spring 11 are fixedly connected to the surfaces of the abutment plate 10 and the clamping plate 9. The connecting spring 11 is in two groups and connected to the abutment plate 10 accordingly. Through the connection between the connecting spring 11 and the abutment plate 10, under the action of the connecting spring 11, a tight fit effect between the abutment plate 10 and the upper shell 1 is achieved.

[0029] Furthermore, the heat dissipation hole 6 is connected to the heat dissipation auxiliary pipe 13, the heat dissipation main pipe 14 is connected to the heat dissipation auxiliary pipe 13, and the heat dissipation auxiliary pipe 13 is evenly opened on both sides of the heat dissipation main pipe 14. Under the connection between the heat dissipation hole 6 and the heat dissipation auxiliary pipe 13, the heat dissipation area of ​​the upper shell 1 to the lithium battery is increased through the connection between the heat dissipation auxiliary pipe 13 and the heat dissipation main pipe 14.

[0030] Working principle: When the lithium batteries in the upper shell 1 and the lower shell 2 are subjected to heat dissipation treatment, the heat dissipation fan 5 is started to rotate to complete the heat dissipation operation of the lithium batteries. Under the passage connection of the heat dissipation main pipe 14 and the heat dissipation auxiliary pipe 13, the heat dissipation area of ​​the upper shell 1 to the lithium batteries is increased through the connection of the heat dissipation auxiliary pipe 13 and the heat dissipation hole 6. When the upper shell 1 and the lower shell 2 are disassembled, the pull ring 12 is pulled to make the card plate 9 slide in the connecting groove 7, thereby separating the abutment plate 10 from the upper shell 1, and completing the separation effect of the upper shell 1 and the lower shell 2.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
