DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

It is arranged at the four corners between the placement plate 1 and the card plate 6, and the spring 5 is arranged between the placement plate 1 and the card plate 6. The battery pack is installed in the placement slot 2, and then the card plate 6 is pressed to compress the telescopic rod 4 and the spring 5, so that the card plate 6 is stuck on the upper side of the battery pack. Then, the bolt 9 is passed through the first connecting block 7 and the second connecting block 8, and the nut on the bolt 9 is tightened to fix the placement plate 1 and the card plate 6 to clamp and fix the battery pack, so that the structure can adjust the distance between the placement plate 1 and the card plate 6, and can be used in combination with battery packs of different sizes.

[0020] In one aspect of the present embodiment, after the card plate 6 contacts the battery pack and fixes the battery, heat is generated when the battery pack is charged and discharged. At this time, the motor 13 fixed by the fixing rod 12 can drive the fan blades 14 to rotate. When the fan blades 14 rotate, suction is generated. This suction is directed toward the battery pack, so that the heat generated by the battery pack is quickly absorbed by the fan blades 14. The heat is drawn away from the mounting frame 11 in the heat dissipation groove 10, so that the heat is finally dissipated into the repair groove 15, thereby dissipating the heat from the repair groove 15. At the same time, the heat generated by the battery pack is also dissipated from the ventilation groove 16.

[0021] In one aspect of the present embodiment, the cover plate 18 is fixed in the card slot 17 by screws, so that the cover plate 18 can cover the repair slot 15, and the setting of the gauze 20 fixed in the connecting slot 19 allows heat to be dissipated through the gauze 20. When the cover plate 18 covers the repair slot 15, it will not affect the heat dissipation. When in use, the placement plate 1 is placed at the position where it needs to be installed. At the same time, when the motor 13 needs to be inspected, the cover plate 18 can be removed to allow the motor 13 to leak out, which is convenient for the inspection and treatment of the motor 13. Thereafter, a fixing part such as a screw is screwed through the fixing hole 23 to the position where it needs to be fixed, so that the structure can be fixed by the fixing plate 22. Through the setting of the rubber pad 21, the two sides of the structure can be anti-collision.

[0022] Working principle of the utility model: when the heat dissipation structure for charging and discharging a battery pack is used, a fixing part such as a screw is passed through the fixing hole 23 and screwed into the position to be fixed, so that the structure can be fixed by the fixing plate 22, and then the battery pack is installed in the placement groove 2, and then the card plate 6 is pressed to compress the telescopic rod 4 and the spring 5, so that the card plate 6 is stuck on the upper side of the battery pack, and then the bolt 9 is passed through the first connecting block 7 and the second connecting block 8, and the nut on the bolt 9 is tightened, so that the placement plate 1 and the card plate 6 are fixed to fix the battery pack, and the battery pack is fixed by fixing The motor 13 fixed by the rod 12 drives the fan blades 14 to rotate. When the fan blades 14 rotate, suction is generated. This suction is directed toward the battery pack, so that the heat generated by the battery pack will be quickly absorbed through the fan blades 14, and the heat will be drawn out from the mounting frame 11 in the heat dissipation groove 10, and finally dissipated through the gauze 20. At the same time, the heat generated by the battery pack will also be dissipated from the ventilation groove 16. When the motor 13 needs to be inspected and repaired, the cover 18 can be removed to allow the motor 13 to leak out, which is convenient for the inspection and treatment of the motor 13. In this solution, all electrical equipment are powered by an external power supply.
