[0006] A storage box is detachably connected to the bottom of the drone body. A connecting plate is detachably installed on the bottom of the drone body. Several fins are fixedly connected to the connecting plate and are located inside the storage box. A No. 1 motor is installed inside the storage box. An exhaust fan blade is fixedly connected to the output end of the No. 1 motor and is located on the outside of the fins. A sealing plate is installed on the storage box and is located on the outside of the No. 1 motor.

The threaded ring is threadedly connected to the positive and negative lead screw, and a set of threaded rings is symmetrically arranged. The extension rod is fixedly installed on the threaded ring, and one end of the extension rod extends through the carrier box. A dust shield is fixedly installed at one end of the extension rod, and the symmetrical dust shields are located in front of the filter screen.
[0008] Preferably, the carrier box is provided with a strip groove, and one end of the extension rod passes through the strip groove and extends out of the interior of the carrier box.
[0009] Preferably, a slide rod is fixedly installed on the sealing plate, and the slide rod is located at the bottom of the filter screen. A slip ring is movably connected to the slide rod, and the slip ring is fixedly connected to the bottom end of the dust cover plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model improves the heat dissipation efficiency of drones by installing fins and exhaust fan blades. First, both the connecting plate and the fins are made of highly thermally conductive materials. The connecting plate is in contact with the electronic components on the drone body that generate heat, and the heat is transferred to the fins through the connecting plate. The fins increase the heat dissipation area. Then, the dust cover is opened to block the filter, allowing outside air to circulate in the storage box through the filter. Next, the No. 1 motor is started to drive the exhaust fan blades to rotate. The rotation of the exhaust fan blades will draw air around the fins. The drawn air will flow through the fins to carry away the heat on the fins, so that the temperature of the fins is relatively lowered, thus forming a temperature difference. This cycle repeats, thereby quickly cooling the drone and ensuring that the drone will not malfunction due to excessive heat in the electronic components during long-term flight.
[0014] 2. This utility model can reduce the impact force of a drone during landing by installing a spring. When the drone lands, it will first contact the ground through the buffer base. The impact force when the ground contacts the drone will be transmitted to the spring through the buffer base. The elasticity of the spring will absorb part of the impact energy, preventing the impact force from acting directly on the drone. At the same time, the damper will control the spring speed. The combined use of the spring and the damper can effectively reduce the damage caused by the impact force to the drone, and further improve the service life of the drone. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1 - Figure 5 A miniature reconnaissance drone includes a drone body 1 and a camera 2. The camera 2 is mounted on the drone body 1. Multiple sets of wings 3 are fixedly mounted on the drone body 1. Rotating blades 4 are provided on the wings 3. Miniature reconnaissance drones are popular due to their small size, light weight, and portability. They are usually used to perform covert reconnaissance and surveillance missions. The drone flies by rotating blades 4. The wings 3 provide stability for the drone's flight. The camera 2 is a high-resolution surveillance device that can provide clear images and video data. However, during long-term flight, the internal temperature of the drone may become too high, which can cause the performance of the internal electronic components to degrade, thereby affecting the drone's flight stability and control accuracy.
[0023] A storage box 5 is detachably connected to the bottom of the drone body 1. A connecting plate 6 is detachably installed on the bottom of the drone body 1. Several fins 7 are fixedly connected to the connecting plate 6, and the fins 7 are located inside the storage box 5. A first motor 8 is installed inside the storage box 5. An exhaust fan blade 9 is fixedly connected to the output end of the first motor 8, and the exhaust fan blade 9 is located on the outside of the fins 7. A sealing plate 10 is installed on the storage box 5, and the sealing plate 10 is located on the outside of the first motor 8. A filter screen 11 is fixedly installed on the sealing plate 10. A dustproof component is provided on the sealing plate 10, and the dustproof component is used to cover the filter screen 11. When improving the heat dissipation efficiency of the drone, the heat dissipation efficiency of the drone can be improved by installing the fins 7 and the exhaust fan blade 9. First, the connecting plate 6 and the fins 7... All fins 7 are made of highly thermally conductive materials. The connecting plate 6 is in contact with the electronic components on the drone body 1 that generate heat. Heat is transferred to the fins 7 through the connecting plate 6. The fins 7 increase the heat dissipation area. Then, the dust cover 18 is opened to cover the filter 11, allowing outside air to circulate in the storage box 5 through the filter 11. Next, the first motor 8 is started to drive the exhaust fan blades 9 to rotate. The rotation of the exhaust fan blades 9 will draw air around the fins 7. The drawn air will flow through the fins 7 to carry away the heat on the fins 7, so that the temperature of the fins 7 is relatively reduced, thus forming a temperature difference. This cycle repeats, so as to quickly cool down the drone and ensure that the drone will not malfunction due to excessive heat of electronic components during long-term flight.
[0024] Please see Figure 2 , Figure 3 and Figure 4 The dustproof assembly includes a carrier box 12, a second motor 13, a forward and reverse lead screw 14, a threaded ring 15, an extension rod 17, and a dust shield 18. The carrier box 12 is fixedly installed on the sealing plate 10 and is located above the filter screen 11. The second motor 13 is fixedly installed inside the carrier box 12. The forward and reverse lead screw 14 is fixedly installed at the output end of the second motor 13. The threaded ring 15 is threadedly connected to the forward and reverse lead screw 14, and a set of threaded rings 15 is symmetrically arranged. The extension rod 17 is fixedly installed on the threaded ring 15, and one end of the extension rod 17 extends through the carrier box 12. A dust shield 18 is fixedly installed at one end of the extension rod 17, and the symmetrical dust shields 18 are located on the filter screen 11. In front of the filter screen 11, a slotted groove 16 is provided on the carrier box 12, and one end of the extension rod 17 passes through the slotted groove 16 and exits the interior of the carrier box 12. When it is not necessary to cool down the drone (especially when the drone is landing), the control device can start the second motor 13 to drive the positive and negative lead screws 14 to rotate. When the positive and negative lead screws 14 rotate, they will drive the extension rod 17 to move linearly in the slotted groove 16 through the threaded ring 15. When the extension rod 17 moves, it will drive the symmetrical dust cover 18 to move relative to each other. The symmetrical dust cover 18 can block the filter screen 11 by closing together, thereby preventing dust and impurities flying when the drone lands from clogging the filter screen 11.
[0025] Please see Figure 2 and Figure 4 A slide rod 19 is fixedly installed on the sealing plate 10, and the slide rod 19 is located at the bottom of the filter screen 11. A slip ring 20 is movably connected to the slide rod 19, and the slip ring 20 is fixedly connected to the bottom end of the dust cover plate 18. When the positive and negative screws 14 drive the dust cover plate 18 to move, the bottom end of the dust cover plate 18 will also slide synchronously on the slide rod 19 through the slip ring 20. The slide rod 19 and the slip ring 20 further limit the bottom end of the dust cover plate 18, providing stability for the movement of the dust cover plate 18.
[0026] Please see Figure 2 and Figure 3 A support plate 21 is fixedly installed inside the storage box 5, and the No. 1 motor 8 is fixedly installed on the support plate 21. The support plate 21 is used to support the No. 1 motor 8 so that the No. 1 motor 8 can be installed in a suitable position.
[0027] Please see Figure 1 and Figure 5Multiple support legs 22 are fixedly installed on the bottom of the drone body 1. The bottom end of the support legs 22 is movably connected to a buffer base 23, and the bottom end of the support legs 22 passes through the buffer base 23. A spring 24 is fixedly installed inside the buffer base 23, and the top end of the spring 24 is fixedly connected to the bottom end of the support leg 22. A damper 25 is fixedly installed inside the buffer base 23, and one end of the damper 25 passes through the interior of the spring 24 and is fixedly connected to the bottom end of the support leg 22. When mitigating the impact force of the drone during landing, the installation of the spring 24 can reduce the impact force of the drone during landing. When the drone lands, it will first contact the ground through the buffer base 23. The impact force when the ground contacts the drone will be transmitted to the spring 24 through the buffer base 23. The elasticity of the spring 24 will absorb part of the impact energy, preventing the impact force from acting directly on the drone. At the same time, the damper 25 will control the elastic speed of the spring 24. The combined use of the spring 24 and the damper 25 can effectively reduce the damage caused by the impact force to the drone, and further improve the service life of the drone.
[0028] The working principle is as follows: By installing fins 7 and exhaust fan blades 9, the heat dissipation efficiency of the drone can be improved. First, both the connecting plate 6 and the fins 7 are made of highly thermally conductive materials. The connecting plate 6 comes into contact with the electronic components on the drone body 1 that generate heat. Heat is transferred to the fins 7 through the connecting plate 6, increasing the heat dissipation area. Then, the dust cover 18 is opened to block the filter 11, allowing outside air to circulate in the storage box 5 through the filter 11. Next, the first motor 8 is started to drive the exhaust fan blades 9 to rotate. The rotation of the exhaust fan blades 9 draws air around the fins 7. The drawn air flows over the fins 7 to carry away the heat on the fins 7, causing the temperature of the fins 7 to decrease relatively, thus creating a temperature difference. This cycle continues. This allows for rapid cooling of the drone, ensuring it won't malfunction due to overheating of electronic components during extended flights. The spring 24 mitigates the impact force during landing. Upon landing, the drone first contacts the ground via the buffer base 23. The impact force is transmitted through the buffer base 23 to the spring 24, whose elasticity absorbs some of the impact energy, preventing direct impact on the drone. Simultaneously, the damper 25 controls the spring speed. The combined use of the spring 24 and damper 25 effectively reduces damage to the drone from impacts, further extending its lifespan.
