Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a heat dissipation cover for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and their own programmed control devices. In recent years, they have experienced rapid technological advancements. Their applications have expanded and deepened, gradually extending from initial military reconnaissance to civilian sectors such as agricultural plant protection, logistics distribution, aerial photography, and environmental monitoring. The emergence of UAVs has not only changed traditional work patterns and improved work efficiency but has also played a crucial role in dangerous or inaccessible environments, bringing immense convenience to human production and daily life.

[0003] With the continuous advancement of drone technology, the market has placed higher demands on the miniaturization of drones. Miniaturized drones offer advantages such as portability, operational flexibility, and strong stealth capabilities, enabling them to better adapt to various complex environments and mission requirements. However, while pursuing miniaturization, drone functionality is becoming increasingly sophisticated, and the number of onboard devices is also growing. In particular, some high-powered devices, such as high-performance processors, high-resolution cameras, and high-power motors, generate significant heat during operation. The concentrated placement of these devices within a confined space exacerbates the problem of heat accumulation inside the drone.

[0004] The bottom cover of a drone not only serves to enclose, support, and secure the internal structure but also needs to provide some degree of heat dissipation. However, the current trend towards miniaturization in drones has resulted in limited structural space and difficult internal airflow, severely impacting the effectiveness of conventional air cooling. Consequently, localized overheating due to high power consumption within the cramped structure is becoming increasingly apparent. Traditional drone bottom covers often rely on ventilation holes for air exchange with the outside air. In the early stages of drone development, this method was sufficient to meet cooling requirements to some extent because the onboard equipment had relatively low power and generated little heat, and the internal space of the drone was relatively spacious. However, with the increasing miniaturization of drones, structural space has become extremely limited, hindering internal airflow. Poor airflow within the confined space prevents heat from being dissipated effectively and promptly, severely impacting the effectiveness of conventional air cooling. Therefore, localized overheating due to high power consumption is becoming increasingly pronounced within the cramped structure. For example, some high-performance aerial photography drones, which use high-resolution cameras and powerful image processing chips, generate a significant amount of heat during operation. If this heat cannot be dissipated in time, it can lead to excessively high camera temperatures, affecting image quality and potentially damaging the equipment. Meanwhile, high temperatures can also affect the performance of drone electronic components, reduce their lifespan, increase the probability of malfunctions, and pose potential risks to the safe flight of drones. Traditional heat dissipation methods are clearly unable to meet the heat dissipation requirements of upgraded drone products, becoming one of the key factors restricting the improvement of drone performance and reliability. Utility Model Content

[0005] This invention provides a heat dissipation cover for drones, which helps to solve the problem of poor heat dissipation performance of some drone bottom covers.

[0006] This utility model is implemented as follows:

[0007] A heat dissipation cover for a drone includes a cover body with an inner cavity that opens at the top. Several vertically arranged mounting posts are located within the inner cavity. These posts are used to connect to the drone body via connectors. A recessed sliding groove is provided on the outer wall of the longitudinal center of each mounting post. A tension spring is fitted at the bottom of the sliding groove, and a sliding sleeve is fitted at the top of the spring. A heat-conducting plate is connected to the sliding sleeves on each mounting post. After the cover body is connected to the drone body, the heat-conducting plate abuts against and supports the target heat dissipation component. Several perforated grooves are provided below the heat-conducting plate on the cover body. Several heat sinks are connected to the bottom of the heat-conducting plate, and the bottoms of the heat sinks extend through the perforated grooves into the outer space of the cover body.

[0008] Based on the above technical solution, the bottom of the cover is provided with a support foot, the length of which is greater than the outward extension of the heat sink relative to the bottom of the cover.

[0009] Based on the above technical solution, the mounting column has a mounting hole in the axial center. The mounting hole is a through hole with an internal thread structure, which can be used to connect and fix the UAV body with bolts.

[0010] Based on the above technical solution, a plug is detachably fitted at the bottom opening of the mounting hole.

[0011] Based on the above technical solution, several mounting columns are evenly distributed in the inner cavity, the heat-conducting plate is a horizontal plate structure, and the heat sink is a vertically arranged plate structure. Both the heat-conducting plate and the heat sink are made of heat dissipation material.

[0012] Based on the above technical solution, the bottom of the heat sink is provided with several serrated notches.

[0013] Based on the above technical solution, a sealing structure made of elastic material is provided between the heat sink and the hollowed-out groove.

[0014] Based on the above technical solution, the top of the heat-conducting plate is provided with a flange structure abutment platform, and the upper surface of the abutment platform is uniformly distributed with anti-slip texture.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. This utility model forms a highly efficient heat dissipation channel through the combination of a heat-conducting plate and a heat sink. The heat-conducting plate can quickly conduct heat from the target heat dissipation component to the heat sink, which then exchanges heat with the outside air through its large surface area, dissipating the heat. Compared with the traditional ventilation method using heat dissipation holes, this heat dissipation method can more effectively reduce the internal temperature of the UAV and solve the problem of heat accumulation in confined spaces.

[0017] 2. The design of the sliding groove, tension spring, and sliding sleeve on the mounting column in this utility model gives the heat-conducting plate a certain elastic buffering capacity. During the flight of the UAV, it may be subjected to vibration and impact. This elastic buffering effect can protect the target heat dissipation components and the heat-conducting plate, avoiding damage caused by hard contact. At the same time, it can also ensure that the heat-conducting plate and the heat dissipation components always maintain good contact, ensuring the stability of heat conduction.

[0018] 3. The bottom of the cover in this invention is provided with a support foot, the length of which is greater than the outward extension of the heat sink relative to the bottom of the cover. This design ensures that the heat sink, when extending into the external space of the cover, will not directly adhere to and seal against the external suspension at the bottom of the drone, preventing heat accumulation between the heat sink and the placement surface. It also facilitates airflow around the heat sink, further improving heat dissipation. Furthermore, the rational structural layout ensures the overall stability and reliability of the heat sink cover.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: Combination Figures 1 to 5 This embodiment discloses a heat dissipation cover for a drone, including a cover body 100, mounting posts 120, tension springs 123, support legs 130, heat-conducting plates 200, and heat sinks 220, etc., aiming to solve the problem of poor heat dissipation in some current drone base covers. Through innovative structural design, the heat dissipation performance of the drone is improved, ensuring that the onboard equipment can operate stably in a suitable temperature environment under the trend of miniaturization and high integration of drones, extending the service life of the drone, and improving its reliability and safety.

[0032] Specifically, in combination Figure 3 As shown, the cover 100 is the main structure of the entire heat dissipation bottom cover. Its outline is a square shell, and its interior has an inner cavity 110 with an opening at the top. The inner cavity 110 provides space for installing other components and also plays a role in heat conduction and dissipation. The shape and size of the cover 100 can be customized according to the specific design requirements of the UAV to ensure a good match with the UAV body 300.

[0033] The inner cavity 110 contains four evenly distributed and vertically arranged mounting posts 120. Each mounting post 120 has a mounting hole 121 with an internal thread at its axial center. These mounting posts 120 are used to connect with connectors (such as bolts) to the drone body 300. A removable plug 124 is provided at the bottom of each mounting hole 121. In this embodiment, the mounting posts 120 are distributed near the four corners of the housing, which makes the internal space more ample. The mounting posts 120 not only fix the heat dissipation base cover but also provide support for the installation of the heat conduction plate 200. A recessed sliding groove 122 is provided on the outer wall of the longitudinal center of the mounting post 120. The sliding groove 122 is actually formed by a variable diameter structure on the outer wall of the mounting post 120. The upper and lower ends of the sliding groove 122 have limiting misalignment steps, combined with… Figure 4 As shown, a tension spring 123 is fitted at the bottom of the sliding groove 122, and the extension and contraction direction of the tension spring 123 is vertical. A sliding sleeve 210 is fitted on top of the tension spring 123 in the sliding groove 122, and a heat-conducting plate 200 is connected to the sliding sleeves 210 on each mounting post 120. This design allows the heat-conducting plate 200 to move up and down within a certain range, providing a certain degree of elastic cushioning. When the cover 100 is connected to the UAV body 300, the heat-conducting plate 200 can abut against and support the target heat dissipation component, ensuring close contact between the heat-conducting plate 200 and the heat dissipation component, thereby improving heat transfer efficiency.

[0034] Furthermore, after the cover 100 is connected to the UAV body 300, the heat-conducting plate 200 can abut against and support the target heat dissipation component. The heat-conducting plate 200 adopts a horizontal plate structure and is made of heat-dissipating materials, such as copper, aluminum, and other metals with good thermal conductivity. In order to take into account economic costs, the heat-conducting plate 200 and the heat sink 220 in this embodiment adopt an integrated aluminum alloy structure. The function of the heat-conducting plate 200 is to quickly conduct the heat generated by the target heat dissipation component away, providing a basis for the subsequent heat dissipation process.

[0035] Combination Figure 3 and Figure 5 As shown, the cover 100 is provided with several hollowed-out grooves 140 below the heat-conducting plate 200. In this embodiment, the hollowed-out grooves 140 are strip-shaped through-hole structures. The design of the hollowed-out grooves 140 increases the contact area between the cover 100 and the external air, which is beneficial for heat dissipation. At the same time, the hollowed-out grooves 140 also provide a channel for the extension of the heat sink 220.

[0036] The number of perforated slots 140 is equal to or greater than the number of heat sinks 220. Several parallel heat sinks 220 are connected to the bottom of the heat-conducting plate 200, and the heat sinks 220 are vertically arranged plate structures. The bottom of the heat sinks 220 extends through the perforated slots 140 into the external space of the cover 100, greatly increasing the heat dissipation area. When the heat-conducting plate 200 conducts heat to the heat sinks 220, the heat sinks 220 dissipate the heat into the surrounding environment through natural convection with the outside air, thereby achieving effective heat dissipation.

[0037] Furthermore, the bottom of the heat sink 220 is provided with several serrated notches, which is another innovation in the heat dissipation design of this utility model. The serrated notches increase the contact area between the heat sink 220 and the air. According to the principle of heat conduction, the larger the heat dissipation area, the higher the heat dissipation efficiency. When air flows through the heat sink 220, the serrated notches cause more turbulence to form at the bottom of the heat sink 220, enhancing the convective heat transfer effect between the air and the heat sink 220. Compared with the traditional flat heat sink 220, this heat sink 220 with a serrated notch structure can more effectively dissipate heat to the surrounding environment, further improving the heat dissipation performance of the drone.

[0038] The bottom of the cover 100 is equipped with a support leg 130, the length of which is greater than the outward extension of the heat sink 220 relative to the bottom of the cover 100. This design ensures that the heat sink 220, when extending into the external space of the cover 100, will not directly adhere to and seal against the external suspension at the bottom of the drone, preventing heat accumulation between the heat sink 220 and the placement surface. It also facilitates airflow around the heat sink 220, further improving heat dissipation. Furthermore, the rational structural layout ensures the overall stability and reliability of the heat sink cover.

[0039] In this embodiment, a recessed sliding groove 122 is provided on the outer wall of the longitudinal center of the mounting column 120. A tension spring 123 is fitted at the bottom of the sliding groove 122, and a sliding sleeve 210 is fitted at the top. The sliding sleeves 210 on each mounting column 120 are connected to the heat-conducting plate 200. This innovative structure has many advantages. From the perspective of heat conduction, it ensures close contact between the heat-conducting plate 200 and the target heat dissipation component. During UAV assembly, the cover 100 is connected to the UAV body 300 through connectors. Under the action of the tension spring 123, the heat-conducting plate 200 abuts against the target heat dissipation component. Regardless of the height difference of the target heat dissipation component due to manufacturing errors or installation tolerances, the heat-conducting plate 200 can adaptively adjust to ensure good contact with each target heat dissipation component and improve heat conduction efficiency. From the perspective of mechanical performance, this structure provides elastic buffering for the heat-conducting plate 200. During flight, the UAV will be subjected to various vibrations and impacts, such as airflow disturbances and collisions during takeoff and landing. Traditional rigid connection heat dissipation structures are prone to relative displacement or collision between the heat-conducting plate 200 and the target heat dissipation component in these situations, which may damage the component or affect heat conduction. However, the elastic connection structure of this invention can effectively absorb and buffer these vibrations and impacts, protecting the target heat dissipation component and the heat-conducting plate 200, and extending their service life.

[0040] Example 2: Based on Example 1, combined with Figure 6 As shown, in this embodiment, the top of the heat-conducting plate is provided with a flanged contact platform 230, and the upper surface of the contact platform 230 is uniformly distributed with anti-slip textures 231. This design ensures stable contact between the heat-conducting plate 200 and the target heat dissipation component. During the flight of the UAV, the target heat dissipation component may have a slight tendency to move due to vibration and acceleration. The flanged contact platform 230 can increase the contact area between the heat-conducting plate 200 and the target heat dissipation component, improving the stability of the connection. The anti-slip textures 231 further increase the friction between the two, preventing the target heat dissipation component from sliding on the heat-conducting plate 200, ensuring the continuity and stability of heat conduction. In practical applications, thermal silicone can also be applied to the contact platform 230 to further improve the heat conduction efficiency.

[0041] In other embodiments, a sealing structure made of elastic material can be provided between the heat sink 220 and the perforated groove 140. This innovation is of great importance. On the one hand, it can prevent dust and moisture from entering the drone's interior. During flight, the drone passes through various environments, such as dusty construction sites and humid air. Without a sealing structure, dust and moisture can easily enter the drone's interior through the perforated groove 140, damaging onboard electronic components. On the other hand, the sealing structure does not affect the thermal expansion and contraction of the heat sink 220. The heat sink 220 expands and contracts due to temperature changes during operation. The elastic material sealing structure can adapt to this change, ensuring a sealing effect without restricting the normal deformation of the heat sink 220.

[0042] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
