Description

Vehicle-mounted high-voltage battery pack of unmanned aerial vehicle Technical Field The utility model relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle-mounted high-voltage battery pack. Background Along with the rapid development of unmanned aerial vehicle technology, the unmanned aerial vehicle is increasingly widely applied to the fields of agricultural plant protection, electric power inspection, emergency rescue and the like. However, the cruising ability of the unmanned aerial vehicle becomes a key factor limiting the working efficiency of the unmanned aerial vehicle when performing a long-time task. To solve this problem, a vehicle-mounted mobile power supply scheme has been developed, that is, a high-voltage battery pack is carried on a vehicle, and an electric wire is used for continuously supplying power to an unmanned aerial vehicle in flight. However, when the vehicle-mounted battery pack is in outdoor operation, the vehicle-mounted battery pack is often exposed to rainwater, high humidity or muddy environment, the waterproof performance of the traditional battery pack is insufficient, the battery is easy to short-circuit, corrode or even thermally run away due to moisture infiltration, and the power supply safety and the service life of equipment are seriously affected. Continuous vibration and shock during vehicle travel can cause the internal connections of the battery pack to loosen, causing poor contact or risk of disconnection. In addition, the high-voltage battery pack can generate a large amount of heat in the long-time discharging process, and if the heat dissipation design is unreasonable, the aging of the battery can be accelerated, and even potential safety hazards are caused. In the prior art, the waterproof design of the battery pack mostly adopts simple sealant or waterproof membrane, but the waterproof design can block part of water vapor, but lacks an active drainage mechanism, and once the sealing is failed or condensed water is accumulated, the internal circuit can be damaged. In the patent CN220628051U, the prior art 1 discloses a lithium battery case, and the prior art 1 includes three main components of the case, namely a base, a protective shell and a top cover. The parts are combined together in a designed connection mode, so that the whole shell is stable and convenient to detach. Specifically, the base is connected with the protective shell through the limiting column and the reinforcing nut, and the top cover is fixed with the protective shell through the fixing screw. The quick assembly disassembly has been realized, the convenience of maintaining and changing has been improved greatly. Particularly, when the lithium battery pack needs to be taken out, the lithium battery pack can be quickly disassembled, and the problem that the traditional integral shell is inconvenient to replace is solved. However, for battery protection, the prior art 1 is not specifically designed for the special requirements of the vehicle-mounted high-voltage battery pack of the unmanned aerial vehicle in outdoor operation, especially in terms of water resistance, shock resistance and heat dissipation.
