[0027] Embodiment:

[0028] As shown in the attached Figure 1 to the attached Figure 5 figure:

[0029] The present utility model provides a drone battery module, which includes a battery housing 1 and a battery module 2. The battery module 2 is installed inside the battery housing 1. A plurality of cooling fans 3 are installed on one side of the battery housing 1, and the cooling fans 3 are installed inside the battery housing 1. By active heat dissipation, the temperature of the battery body 5 is reduced, improving the performance and lifespan of the battery body 5. On the side of the battery housing 1 away from the cooling fans 3, there is a BMS balanced battery information acquisition port 4. The battery module 2 includes a plurality of battery bodies 5, battery brackets 6, and battery elastic connection sheets 7. A pair of battery brackets 6 are installed on the upper and lower end faces of the plurality of battery bodies 5. A plurality of battery elastic connection sheets 7 are installed on the upper end face of the battery bracket 6 located above. On one side of the upper end face of the battery elastic connection sheet 7, a pair of elastic mechanisms 701 are installed, and on the other side of the upper end face of the battery elastic connection sheet 7, three groups of elastic mechanisms 702 are installed. Through the combined use of the battery elastic connection sheet 7, the elastic mechanism 701, and the elastic mechanism 702, the design of the battery elastic connection sheet 7 has a structure with tensile elasticity, thus being able to adapt to the thermal expansion and contraction of the battery, preventing the battery elastic connection sheet 7 from breaking and the solder joints from falling off. The battery body 5, the battery bracket 6, the battery elastic connection sheet 7, and the battery housing 1 are bonded together by soft silicone. The soft silicone can provide shock absorption and reinforcement, thereby reducing the impact of vibration on the battery module 2.

[0030] Among them, on one side of the battery housing 1 near the BMS balanced battery information acquisition port 4, a pair of high-current plugs 8 are installed. Through the high-current plugs 8, the battery body 5 can be charged.

[0031] Among them, on one side of the battery housing 1 below the BMS balanced battery information acquisition port 4, a control switch 9 is installed. Through the control switch 9, the turning on and off of the cooling fans 3 can be controlled.

[0032] Among them, on one side of the battery housing 1 near the control switch 9, a pair of voltage and temperature meters 10 are installed. Through the voltage and temperature meters 10, the voltage and temperature of the battery module 2 can be displayed.

[0034] Among them, the material of the battery housing 1 is aluminum alloy. Aluminum alloy has a relatively low density and high strength, with a lighter weight than many other structural materials such as steel. Aluminum alloy has good corrosion resistance, and its surface can be further enhanced in corrosion resistance through anodic oxidation or other surface treatment technologies, enabling it to maintain stable performance in harsh environments (or other materials with relatively high specific strength, engineering plastics, composite materials).

[0035] Among them, a pair of heat dissipation grooves 12 are provided on both sides of the battery housing 1. Quick self-locking limit buckles (which are prior arts and will not be elaborated here) are respectively installed at the edges on both sides of the heat dissipation grooves 12. The cooling fan 3 blows the external cold air onto the surface of the battery body 5 for heat dissipation, and the hot air inside the battery housing 1 is discharged through the heat dissipation grooves 12.

[0036] The working principle of this embodiment:

[0037] Through the combined use of the BMS balanced battery information acquisition port 4 and the battery module 2, the battery module 2 adopts an external battery protection system. The charger current enters the battery module 2 after passing through the battery protection system. The battery protection system collects the information of the battery module 2 through the BMS balanced battery information acquisition port 4, thereby reducing the overall weight and improving the load capacity of the drone. Through the use of the cooling fan 3, the cooling fan 3 is installed inside the battery housing 1, and the temperature of the battery body 5 is reduced by active heat dissipation, improving the performance and lifespan of the battery body 5. Through the combined use of the battery elastic connecting piece 7, the elastic mechanism one 701, and the elastic mechanism two 702, the design of the battery elastic connecting piece 7 has a structure with tensile elasticity, so as to be able to adapt to the thermal expansion and contraction of the battery, prevent the battery elastic connecting piece 7 from breaking and the solder joints from falling off. At the same time, the battery body 5, the battery bracket 6, the battery elastic connecting piece 7, and the battery housing 1 are bonded together by soft silicone, which can perform shock absorption and reinforcement, and thus can reduce the impact of vibration on the battery module 2.
