[0002] As we all know, with the rapid development of drone technology, drones are being used more and more widely. However, drone batteries generate a lot of heat during charging, which will affect the performance and life of the battery if it cannot be dissipated in a timely and effective manner.

[0003] Although the existing drone battery cooling box can dissipate heat to a certain extent, the cooling effect is not ideal. During long-term use, the cooling fan is prone to accumulate dust and dirt, which will hinder air flow and reduce cooling efficiency. Regular disassembly, cleaning or maintenance is required. If the cooling fan cannot be easily disassembled and replaced, cleaning will become difficult, which may lead to a decrease in cooling effect. If the cooling fan fails and needs to be repaired or replaced, the design that is not easy to disassemble will increase the difficulty and time cost of maintenance. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] See also Figure 1-4A battery heat dissipation box for unmanned aerial vehicles comprises a box body 1, a box cover 2, a heat dissipation fan 3 and a locking device. The top of the box body 1 is hingedly connected to the box cover 2, and the four corners of the bottom end of the box body 1 are equipped with supporting legs 4. The inner cavity of the box body 1 is provided with a battery charging slot 5, and grooves 6 are provided above the left and right sides of the box body 1. A heat dissipation frame 7 is installed in the groove 6 through a locking device, and a heat dissipation fan 3 is installed in the heat dissipation frame 7. The locking device comprises a spring 8, a movable plate 9, a positioning column 10, a positioning groove 11 and a pulling column 12. A accommodating cavity 13 is provided in the box body 1. The movable plate 9 is slidably installed in the accommodating cavity 13, two groups of the springs 8 are installed at one end of the movable plate 9, and two groups of the positioning columns 10 are symmetrically connected to the other end of the movable plate 9. Two groups of positioning grooves 11 are opened on the side wall of the heat dissipation frame 7 close to the positioning columns 10, and the positioning grooves 11 are adapted to the positioning columns 10. The pulling column 12 is installed at the center position of one end of the movable plate 9 close to the spring 8. A through hole 14 penetrating the accommodating cavity 13 is opened on the side wall of the box body 1, and the pulling column 12 penetrates the through hole 14 and extends to the outside of the box body 1. In this embodiment, when in use, before installing the heat dissipation fan 3 into the box body 1, first pull the pulling column 12 outward, and the pulling column 12 drives the movable plate 9. When the movable plate 9 moves toward the pulling column 12, it drives the two sets of springs 8 to be compressed, so that the two sets of positioning columns 10 installed at the other end of the movable plate 9 are stored in the accommodating cavity 13, and then the heat dissipation frame 7 drives the heat dissipation fan 3 to be inserted into the groove 6. Then, when the heat dissipation frame 7 is adapted to the groove 6, release the pulling column 12. When the pulling column 12 is released, the spring 8 stretches, driving the movable plate 9 to move in the direction of the heat dissipation frame 7 until the positioning column 10 is moved in. The cooling fans 3 are inserted into the positioning groove 11 to lock the heat dissipation frame 7 with the locking device, so that the cooling fans 3 can be quickly installed and removed. Then, when the UAV battery is placed in the battery charging slot 5 in the box body 1 for charging, the two sets of cooling fans 3 are started to work. The forced convection effect of the two sets of cooling fans 3 can speed up the heat transfer speed and improve the heat dissipation efficiency. Compared with relying solely on natural convection heat dissipation, the installation of the cooling fans 3 can reduce the battery temperature more quickly and reduce the risk of thermal runaway of the battery. The cooling fans 3 installed on the left and right sides can better adapt to different environments and ensure that the battery can be effectively cooled under various conditions.

[0026] During actual use, the installation of the heat dissipation frame 7 is further limited. In this embodiment, a limiting block 15 is fixedly installed on the top of the heat dissipation frame 7, and a limiting groove 16 is provided on the top of the groove 6. The limiting groove 16 is adapted to the limiting block 15. When the heat dissipation frame 7 drives the heat dissipation fan 3 to be installed into the groove 6, the limiting block 15 enters the limiting groove 16, and the limiting block 15 serves to limit the heat dissipation frame 7.

[0027] During actual use, it further guides the installation of the heat dissipation frame 7. In this embodiment, a guide bar 17 is installed on the side of the heat dissipation frame 7 away from the locking device, and a guide groove 18 is opened on the side of the groove 6 away from the locking device. The guide groove 18 is adapted to the guide bar 17. Before the heat dissipation frame 7 enters the groove 6, the guide bar 17 is first aligned with the guide groove 18, and the guide bar 17 is inserted into the guide groove 18, which can guide the installation of the heat dissipation frame 7 and facilitate the locking of the heat dissipation frame 7 by the locking device at a later time.

[0028] In actual use, the heat dissipation effect of the bottom wall of the box body 1 is further improved. In this embodiment, the bottom wall of the box body 1 is symmetrically arranged on the left and right or front and back, and four groups of heat dissipation areas 19 are arranged. Air ducts 20 are arranged between the four groups of heat dissipation areas 19. A number of heat dissipation fins 21 are inclined and evenly arranged in the four groups of heat dissipation areas 19. An air flow channel 22 is arranged between each group of the heat dissipation fins 21. The four groups of heat dissipation areas 19 allow air to flow into the heat dissipation fins 21 from four directions through the air flow channel 22. The heat on the bottom wall of the box body 1 can generate convection with the air from four directions to accelerate the heat dissipation. The air enters from one side and can flow out from any one of the other three directions, and the air can also flow freely in all directions in the heat dissipation fins 21. The area of ​​the heat dissipation fins 21 through which the air flows is increased, which can take away more heat, so that the four heat dissipation areas 19 can better cooperate with each other, and the heat dissipation effect of the bottom wall of the box body 1 is further improved.

[0029] Preferably, in this embodiment, the plurality of heat sink fins 21 are made of copper, which is an excellent thermal conductive material having high thermal conductivity, low resistivity and good plasticity, and can quickly transfer the heat absorbed by the heat sink fins 21 to the surrounding environment.

[0030] Preferably, in this embodiment, a plurality of ventilation slots 23 penetrating the inner cavity of the box body 1 are provided at the top of the box cover 2. The ventilation slots 23 allow external air to enter the interior of the box body 1, thereby increasing the air circulation in the box body 1. Together with the two sets of cooling fans 3, this helps to take away the heat generated by the battery and improve the heat dissipation effect.

[0031] In actual use, in order to further ensure the stability of the support leg 4, in this embodiment, a shock-absorbing pad is installed on the bottom wall of the support leg 4. The installation of the shock-absorbing pad can increase the friction between the support leg 4 and the ground, reduce the movement or tilt of the support leg 4 caused by ground movement or vibration, and thus increase the support stability of the support leg 4.

[0032] In actual use, in order to further facilitate pulling the pulling column 12, in this embodiment, a pulling plate 24 is installed at the end of the pulling column 12. The pulling plate 24 facilitates pulling the pulling column 12 and limits the pulling column 12 to prevent the pulling column 12 from entering the accommodating cavity 13 through the through hole 14.

[0033] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.
