Abstract
Description
Technical Field
[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a lightweight UAV shell. Background Technology
[0002] As an important aerial operation platform, drones have been widely used in many fields such as aerial photography, logistics transportation, agricultural plant protection, and environmental monitoring due to their high mobility, low cost, and flexible operation. In the airframe structure of drones, the lightweight drone shell is the core component that protects the internal precision electronic components, such as flight controllers, batteries, and sensors. The rationality of its structural design directly affects the overall performance and service life of the drone.
[0003] During prolonged high-intensity operation, the internal components of a drone, such as the processor, battery, and motor, generate a significant amount of heat. To ensure stable drone performance and the safety of electronic components, this heat must be dissipated promptly and effectively. Currently, common lightweight drone shells typically dissipate heat by opening ventilation holes or incorporating small fans. However, this design has significant limitations. When the drone is hovering, flying at slow speeds, or flying in crosswinds, the natural airflow through the ventilation holes is greatly reduced, resulting in decreased heat dissipation efficiency. While built-in fans can provide active cooling, their fixed airflow direction cannot always adapt to the complex and ever-changing airflow direction during drone flight, leading to unstable cooling performance and additional consumption of valuable electrical energy, thus shortening the drone's flight time.
[0004] Furthermore, when the internal components of a drone need to be inspected, cleaned, or replaced, most existing lightweight drone shells use an integrated or multi-piece shell structure fastened with screws. This structure makes the maintenance process very cumbersome. Operators need to remove a large number of screws and carefully separate the shell, which is not only time-consuming and laborious, but also very easy to damage the shell clips or the delicate internal wiring during disassembly and assembly, increasing the difficulty and risk of maintenance.
[0005] Therefore, this utility model proposes a lightweight drone shell to address the shortcomings of existing technologies. Utility Model Content
[0006] In view of the problems in the existing lightweight drone shell, such as the heat dissipation efficiency being easily affected by the flight direction, resulting in unstable heat dissipation, and the inconvenience and cumbersome operation of internal equipment maintenance and disassembly, this utility model aims to provide a lightweight drone shell with an improved structure that can effectively solve the above problems.
[0007] This utility model provides a lightweight drone shell, including: a high-strength outer shell; a maintenance mechanism, the maintenance mechanism including a movable door hinged to the high-strength outer shell and a mounting plate disposed inside the movable door; and a heat dissipation mechanism.
[0008] The lightweight drone housing also includes a spring rod and a rotating cover.
[0009] The spring rod, as part of the maintenance mechanism, is used to push the mounting plate out of the high-strength outer shell after the movable door is opened.
[0010] Furthermore, the rotating cover, as part of the heat dissipation mechanism, is rotatably mounted on the high-strength outer shell. The rotating cover is provided with a fan plate and an air inlet, and fan blades are provided inside the rotating cover. Both the maintenance mechanism and the heat dissipation mechanism are located on the high-strength outer shell.
[0011] Preferably, the air deflector is disposed on the outer wall of the rotating cover, and the air deflector is used to drive the rotating cover to rotate under the action of airflow.
[0012] Preferably, the fan blades are used to rotate under the blowing of airflow through the air inlet to enhance heat dissipation inside the high-strength housing.
[0013] Preferably, the heat dissipation mechanism further includes a filter screen disposed inside the rotating cover, and a vent for discharging impurities that connects the inside and outside of the rotating cover.
[0014] Furthermore, the filter is located on the airflow path between the air inlet and the fan blade.
[0015] Preferably, the maintenance mechanism further includes a plug-in plate disposed on the high-strength outer shell, the plug-in plate being used to detachably engage with the movable door.
[0016] Preferably, one end of the spring rod is connected to the mounting plate, and the other end abuts against the interior of the high-strength housing.
[0017] Preferably, the lightweight drone shell also includes feet, which are fixed to the bottom of the high-strength shell.
[0018] This utility model has the following beneficial effects:
[0019] 1. This utility model, by setting up a heat dissipation mechanism composed of a wind vane, a rotating cover, and fan blades, utilizes the airflow during the flight of the drone to blow the wind vane and drive the rotating cover to rotate, so that the air inlet is always aligned with the direction of the incoming flow. This solves the problem in the prior art that the heat dissipation effect of the drone is affected by the flight attitude and direction, resulting in unstable heat dissipation efficiency. It achieves the beneficial effect of omnidirectional, efficient and stable heat dissipation of the drone's interior.
[0020] 2. This utility model, by setting up a maintenance mechanism consisting of a movable door, a mounting plate, and a spring rod, allows the mounting plate containing the internal equipment to be pushed out of the shell by unlocking the movable door and using the extension and retraction of the spring rod when maintenance is required. This solves the problems of cumbersome disassembly and assembly process, limited operating space, and difficulty in comprehensive maintenance when inspecting the internal equipment of UAVs in the prior art. It achieves the beneficial effect of quickly and conveniently removing core components and facilitating comprehensive maintenance and cleaning. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0029] Example:
[0030] Please refer to Figure 1 and Figure 2The lightweight drone shell comprises a high-strength outer shell 1, a heat dissipation mechanism 2 and a maintenance mechanism 3 mounted on the high-strength outer shell 1, and feet 4 fixedly connected to the bottom of the high-strength outer shell 1. The feet 4 provide stable ground support for the drone, and the maintenance mechanism 3 serves to support and maintain the internal equipment. Specifically, refer to... Figure 3 and Figure 5 The maintenance mechanism 3 includes a hinged door 32 that is connected to the rear end of the high-strength housing 1 via a hinge 31. The door 32 can be opened by rotating around the hinge 31. A mounting plate 33 is detachably fixed to the inner side of the door 32, serving as a platform for supporting internal electronic equipment. The maintenance mechanism 3 also includes a plug-in plate 34 disposed on the high-strength housing 1, which engages with the front end of the door 32 to lock the door 32 closed. In addition, the maintenance mechanism 3 is provided with a spring rod 35 connecting the mounting plate 33 and the interior of the high-strength housing 1. The heat dissipation mechanism 2 provides cooling. Specifically, refer to... Figure 4 The heat dissipation mechanism 2 includes a rotating cover 21 that is rotatably mounted on the front side of the high-strength outer shell 1. A fan plate 22 is fixedly connected to the outer wall of the rotating cover 21. An air inlet 24 is provided on the rotating cover 21. A fan blade 23 is rotatably connected to the inside of the rotating cover 21 through a rotating shaft. A filter screen 25 and a waste discharge port 26 are also provided inside the rotating cover 21.
[0031] Please refer to Figure 1 , Figure 2 and Figure 4 The rotating cover 21 of the heat dissipation mechanism 2 is rotatably mounted on the front of the high-strength outer shell 1. The fan plate 22 is fixedly connected to the outer wall of the rotating cover 21. When the drone is in flight, the airflow blows the fan plate 22, which drives the rotating cover 21 to rotate, so that the air inlet 24 on the rotating cover 21 can automatically face the direction of the airflow. The airflow enters the interior of the rotating cover 21 through the air inlet 24 and passes through the filter 25 located in the airflow path between the air inlet 24 and the fan blade 23. The filter 25 filters impurities in the air, and the filtered airflow blows the fan blade 23 to rotate. The rotation of the fan blade 23 enhances the heat dissipation effect on the interior of the high-strength outer shell 1 of the drone. The impurities intercepted by the filter 25 are discharged through the exhaust port 26. At the same time, please refer to Figure 3 and Figure 5 The movable door 32 of the maintenance mechanism 3 is hinged to the high-strength housing 1 via a hinge 31. The plug plate 34 is disposed on the high-strength housing 1 and is detachably engaged with the movable door 32 to lock the movable door 32. One end of the spring rod 35 is connected to the mounting plate 33, and the other end abuts against the inside of the high-strength housing 1. When the movable door 32 is closed, the spring rod 35 is in a compressed state. When the plug plate 34 is released and the movable door 32 is opened, the spring rod 35 releases its elastic force and pushes the mounting plate 33 disposed on the inside of the movable door 32 outward.
[0032] As a preferred embodiment, refer to Figure 4 In order to enable the rotating cover 21 to respond sensitively to the airflow direction, multiple wind vanes 22 are preferably distributed evenly on the outer wall of the rotating cover 21. The surface of the wind vanes 22 can be set as an arc surface to increase the windward area and improve the rotation efficiency. The fan blades 23 are rotatably connected to the inside of the rotating cover 21 through bearings and face the inside of the air inlet 24 to ensure that the incoming airflow can drive the fan blades 23 to rotate with maximum efficiency.
[0033] As another preferred implementation, refer to the following: Figure 4 In order to filter the air entering the high-strength outer shell 1 and keep the heat dissipation channel unobstructed, the filter 25 inside the heat dissipation mechanism 2 is a detachable structure, which is convenient for cleaning or replacement. The mesh size of the filter 25 is selected according to the usage environment of the UAV. The impurity discharge port 26 is opened on the lower side wall of the rotating cover 21 so that heavier impurities intercepted by the filter 25 can be smoothly discharged under the action of gravity.
[0034] As another preferred implementation, refer to Figure 3 and Figure 5 In order to achieve reliable locking and quick release of the movable door 32, the plug plate 34 is integrally formed on the opening edge of the high-strength outer shell 1. The movable door 32 is provided with a corresponding slot that matches the plug plate 34. Locking is achieved by the elastic engagement of the plug plate 34 and the slot. At the same time, the spring rods 35 are preferably two, symmetrically arranged on both sides of the mounting plate 33, to ensure that a smooth and uniform pushing force can be provided to push the mounting plate 33 out after unlocking.
[0035] As a preferred embodiment, refer to Figure 1 and Figure 2 To ensure the stability of the drone when it is parked on the ground, there are four feet 4, which are fixedly connected to the four corners of the bottom of the high-strength shell 1. The bottom of the feet 4 can also be equipped with rubber anti-slip pads to increase friction and absorb the impact during landing.
[0036] Working principle: The foot 4 provides support for the device when the high-strength shell 1 of the drone is placed. When the drone is in use, the airflow blows the fan plate 22 in the heat dissipation mechanism 2. The airflow guided by the fan plate 22 can drive the rotating cover 21 to rotate along the high-strength shell 1, so that the air inlet 24 always faces the airflow direction when the drone is moving. At this time, the airflow will enter the rotating cover 21 and blow the fan blade 23 to rotate. Through the further guidance of the fan blade 23 and the filtration of the filter screen 25, the device inside the high-strength shell 1 can be cooled when the drone is in motion. At the same time, the impurities intercepted by the filter screen 25 can be discharged through the impurity outlet 26.
[0037] Furthermore, the hinge 31 in the maintenance mechanism 3 can open and close the movable door 32 to perform preliminary maintenance on the internal structure of the high-strength outer shell 1. At this time, the connection between the internal equipment and the surrounding drone propellers is disconnected, and the locking and fixing between the movable door 32 and the plug plate 34 is also released. The mounting plate 33 and the equipment installed on it can be ejected from the outside of the device by the extension and retraction of the spring rod 35, so as to facilitate comprehensive maintenance and cleaning operations.
