Description

Technical Field

[0001] The utility model relates to the technical field of drone batteries, in particular to a drone battery that is convenient for heat dissipation. Background Art

[0002] A drone is an unmanned aircraft that is controlled by a radio remote control device and a self-contained program control device. Drones can be divided into fixed-wing drones, unmanned helicopters and multi-rotor drones according to different platform configurations. The technical characteristics of drones include autonomous flight capability, mission payload carrying capacity, remote control capability, etc. Drones can fly according to preset programs or remote commands to complete various tasks such as reconnaissance, monitoring, filming, and transportation.

[0003] Currently, drones are usually equipped with batteries for flight power. Since drones consume a lot of power during flight, the battery discharge current is very large, so the battery generates a lot of heat. Most batteries on the market are not specially designed for battery heat dissipation, which will cause heat accumulation inside the battery, affecting the battery life and even flight safety. To this end, we propose a drone battery that is easy to dissipate heat. Utility Model Content

[0004] The main purpose of the present invention is to provide a drone battery that is easy to dissipate heat. A heat dissipation mechanism is set at the existing drone body, battery compartment and battery block. The battery block dissipates heat from the point heat dissipation holes of the heat dissipation mechanism into the inner cut groove. Then, a bottom embedded plate is provided in the inner cut groove below the battery block and cooperates with a thermally conductive silicone sheet to transfer heat to the fins. The fins encounter airflow during the flight of the drone body to dissipate wind heat, thereby taking away the heat dissipated from the battery block. In addition, the side through grooves outside the battery block enable the heat of the battery block to be better dissipated. The U-shaped compartment wall groove and the bottom through groove in the battery compartment are interconnected, so that the heat in the battery compartment is transferred to the fins, assisting the battery compartment and the battery block to perform efficient external conduction heat dissipation when the drone body takes off, which can effectively solve the problems in the background technology.

The thermally conductive silicone sheet is glued to the groove wall of the inner groove, and an array of fins is fixed on the lower plate surface of the bottom panel away from the partition groove. A bottom through groove is provided through the lower wall of the battery compartment, and fins are provided in the bottom through groove to pass downward out of the battery compartment and the drone body. U-shaped compartment wall grooves are symmetrically provided on both sides of the battery compartment outside the battery block, and side through grooves are provided on the vertical block surfaces on both sides of the battery block.

[0009] Furthermore, an array of point-type heat dissipation holes is provided on the wide groove wall surface of the inner cut groove, and the groove wall of the inner cut groove below the battery block contacts the thermal conductive silicone sheet through the point-type heat dissipation holes;

[0010] By adopting the above technical solution, point-type heat dissipation holes are opened on the groove wall of the inner groove, thereby partially weakening the shell thickness of the battery block, thereby increasing the heat dissipation capacity of the battery block.

[0011] Furthermore, the groove cavity of the surface cutting groove is a rectangular groove cavity with a partition plate in the middle;

[0012] By adopting the above technical solution, a partition plate is reserved in the groove cavity of the surface cut groove as a rib structure to ensure the strength of the outer shell of the drone body at the surface cut groove.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model sets a heat dissipation mechanism on the existing drone body, battery compartment and battery block. The battery block dissipates heat from the point heat dissipation holes of the heat dissipation mechanism into the inner cut groove. Then, a bottom embedded plate in the inner cut groove below the battery block cooperates with a heat-conducting silicone sheet to transfer heat to the fins.
