Description

Technical Field

[0001] This invention relates to the technical field of aerospace engineering, and more particularly to a solar-powered unmanned aerial vehicle. Background Technology

[0002] In recent years, with the development of solar cell technology, a more powerful energy source has been provided for solar-powered unmanned aerial vehicles (UAVs). These high-efficiency solar cells can better convert sunlight into electrical energy, thereby increasing the flight time of the aircraft. Many solar-powered UAVs use lightweight and high-strength materials such as carbon fiber composites, making the structure of the fuselage lighter and stronger, which helps to improve flight efficiency and payload capacity.

[0003] Some existing solar-powered unmanned aerial vehicles (UAVs) typically retract their landing gear into the fuselage. While this method reduces air resistance, improves flight efficiency, and increases endurance, it can take up valuable internal space for solar-powered aircraft that rely on high-efficiency batteries for extended flight, thus affecting battery installation space. Furthermore, the landing gear tires of some solar-powered UAVs often have the drawback of being difficult to replace flexibly. Different landing environments may require different types of tires (e.g., smooth tires on hard surfaces to reduce rolling resistance, and tires with deep treads on soft ground to increase traction). If the tires are not easy to replace, it may limit the aircraft's adaptability to various ground conditions. Summary of the Invention

Therefore, the invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0029] Example 1 Reference Figures 1-5This is the first embodiment of the present invention, which provides a solar-powered unmanned aerial vehicle, the device comprising: The aircraft body 100 includes a fuselage 101, wings 102 respectively adapted to be installed on the outer surfaces of both sides of the fuselage 101, a photovoltaic panel 103 fixedly connected to the top of the fuselage 101, a camera 104 fixedly installed on the inner surface of the fuselage 101, legs 105 respectively fixedly connected to the bottom of both sides of the fuselage 101, and tires 106 respectively disposed on the lower sides of both sides of the fuselage 101. It should be noted that the fuselage 101 is the main structure of the entire aircraft body 100 and is used to install other components. The wings 102 are used to provide lift, the photovoltaic panels 103 are used to collect solar energy and convert it into electrical energy, the camera 104 is used for shooting and monitoring, the outriggers 105 are used to support the fuselage 101 when the tires 106 are retracted, and the tires 106 are used to cushion the take-off, landing and movement of the aircraft body 100.

[0030] The take-up and take-down mechanism 200 includes a support component 201 fixedly connected to the bottom of the body 101, a drive component 202 disposed on the surface of the body 101 and used to take up and put down the tire 106 from the back of the body 101, and a disassembly and assembly component 203 disposed on the outer surface of the drive component 202 and used to quickly change different types of tires 106. The load-bearing component 201 includes a connecting column 201a fixedly installed at the bottom of the body 101, and a fixing plate 201b fixedly connected to the other end of the connecting column 201a.

[0031] The drive assembly 202 includes an inlet cylinder 202a adapted to be installed on the top of the connecting column 201a, a connecting block 202b fixedly installed on the output end of the inlet cylinder 202a, a rack 202c fixedly connected to the outer end face of the connecting block 202b, a gear 202d meshing with the outer surface of the rack 202c, a drive rod 202e fixedly connected to the inner surface of the gear 202d, a universal joint 202f fixedly connected to both ends of the drive rod 202e, a transmission rod 202g fixedly installed on the other end of the universal joint 202f, a swing arm 202h fixedly connected to the inner surface of the transmission rod 202g, and support blocks 202i fixedly connected to the bottom of both sides of the connecting column 201a and used in conjunction with the transmission rod 202g. It should be noted that the connecting column 201a is used to connect the fixing plate 201b, and the fixing plate 201b is used to support the drive assembly 202. When the output end of the jacking cylinder 202a extends, it can drive the rack 202c to move linearly along the limiting groove 201c. The rack 202c drives the gear 202d and the drive rod 202e to rotate. Then, the support block 202i limits the transmission rod 202g, so that the drive rod 202e drives the transmission rod 202g, the swing arm 202h, the disassembly assembly 203 and the tire 106 to rotate synchronously through the universal joint 202f.

[0032] When the output end of the jacking cylinder 202a is fully extended, it can drive the swing arm 202h to move to a position parallel to the bottom of the fuselage 101, and drive the tire 106 to the back of the fuselage 101 through the disassembly and assembly component 203 to reduce wind resistance during flight.

[0033] Specifically, the inner cavity of the fuselage 101 is equipped with a battery for use with the photovoltaic panel 103, and the outriggers 105 are used to support the fuselage 101 when the tires 106 are retracted.

[0034] Furthermore, the connecting post 201a also includes a limiting groove 201c opened at the top of the connecting post 201a and used in conjunction with the rack 202c, and a sliding groove 201d opened at the bottom of the connecting post 201a and used in conjunction with the connecting block 202b.

[0035] The outer surface of the connecting block 202b is in sliding contact with the inner surface of the slide groove 201d, and the rack 202c is slidably connected to the inner wall of the limiting groove 201c.

[0036] Preferably, a rotating bearing sleeve is installed at the connection between the drive rod 202e and the connecting column 201a, and the outer end face of the transmission rod 202g is fixedly installed on the outer surface of the support block 202i by the bearing.

[0037] During use, in the flight preparation phase: before flight, the tires 106 are located on both sides of the fuselage 101. At this time, the outriggers 105 are suspended in the air, while the photovoltaic panels 103 begin to collect solar energy and convert it into electrical energy, which is stored in the battery inside the fuselage 101 to provide energy support for subsequent flight. When the aircraft body 100 takes off: the jacking cylinder 202a is activated, so that the output end of the jacking cylinder 202a is fully extended, and the connecting block 202b is driven to move linearly along the limiting groove 201c. The connecting block 202b drives the rack 202c to move synchronously, and the rack 202c drives the gear 202d to rotate accordingly. The rotation of the gear 202d is transmitted to the universal joints 202f at both ends through the drive rod 202e, and then the universal joints 202f drive the transmission rod 202g to rotate. The rotation of the transmission rod 202g finally drives the disassembly and assembly assembly 203 and the tire 106 to rotate synchronously through the swing arm 202h. During this process: the support block 202i limits the transmission rod 202g, ensuring that the transmission rod 202g can only rotate around the predetermined axis and will not deviate from the track; As the output end of the top-mounted cylinder 202a is fully extended, the swing arm 202h and the disassembly assembly 203 are moved to a position parallel to the bottom of the fuselage 101. At this time, the disassembly assembly 203 will drive the tire 106 to move to the back of the fuselage 101 to reduce air resistance during flight and improve flight efficiency. When the aircraft body 100 completes its mission and needs to land: the output end of the control jacking cylinder 202a retracts, a process opposite to that during takeoff: the rack 202c slides in the opposite direction along the limiting groove 201c, driving the gear 202d to rotate in the opposite direction, thereby causing the drive rod 202e, universal joint 202f, transmission rod 202g, and swing arm 202h to rotate in the opposite direction in sequence. Finally, the disassembly and assembly assembly 203 moves the tires 106 back to their original positions on both sides of the fuselage 101 to facilitate a smooth landing of the aircraft body 100. After the aircraft body 100 stops gliding, the outriggers 105 take over the task of supporting the fuselage, enabling the aircraft body 100 to remain stable on the ground.

[0038] In summary, through the cooperation of the support component 201 and the drive component 202, the tires 106 can be moved to the back of the fuselage 101 during the flight of the aircraft body 100, which significantly reduces air resistance during flight. By reducing air resistance, the energy consumed by the aircraft body 100 during flight is reduced, thereby improving the flight efficiency and endurance of the aircraft body 100.

[0039] Example 2 Reference Figure 3 , Figure 4 , Figure 6 and Figure 7 This is a second embodiment of the present invention, which differs from the first embodiment in that: this embodiment provides a disassembly and assembly assembly 203 that can quickly replace different types of tires 106 according to different landing environments.

[0040] It should be noted that the disassembly and assembly assembly 203 includes a mounting shaft 203a fixedly mounted on the outer surface of the swing arm 202h via a bearing, a star-shaped guide rail 203b fixedly connected to the other end of the mounting shaft 203a, a fixing block 203c fixedly mounted on the outer surface of the star-shaped guide rail 203b, and a worm gear 203d rotatably connected to the inner surface of the fixing block 203c.

[0041] It should also be noted that the mounting shaft 203a serves as a bridge connecting the swing arm 202h and the star-shaped guide rail 203b, ensuring that the entire assembly 203 can rotate synchronously under the drive of the swing arm 202h. The fixing block 203c is used to install the worm gear 203d.

[0042] Furthermore, the disassembly and assembly assembly 203 also includes a worm wheel 203e meshing with the outer surface of the worm 203d, a plurality of arc-shaped grooves 203f arranged in a circumferential array on the outer surface of the worm wheel 203e, a limiting post 203g located inside the arc-shaped groove 203f, and a sliding rod 203h fixedly connected to the outer end face of the limiting post 203g and located inside the star-shaped guide rail 203b.

[0043] The rotation of the worm 203d directly drives the worm wheel 203e meshing with it, thereby triggering the subsequent extension and retraction of the support plate 203i. The arc-shaped groove 203f changes position with the rotation of the worm wheel 203e and provides a sliding path for the limiting post 203g, ensuring that the limiting post 203g moves along a predetermined trajectory. The shape of the star-shaped guide rail 203b is used to limit the sliding rod 203h, so that the sliding rod 203h can only expand or contract in a circular manner within it through the movement of the limiting post 203g, thereby achieving the effect of driving the support plate 203i to extend and retract.

[0044] Furthermore, the assembly / disassembly assembly 203 also includes a support plate 203i fixedly connected to the outer end face of the sliding rod 203h and used in conjunction with the tire 106, and a positioning column 203j fixedly installed on the outer surface of the star-shaped guide rail 203b and used in conjunction with the worm gear 203e.

[0045] It should be explained that the sliding rod 203h is responsible for transmitting the linear motion of the limiting post 203g to the support plate 203i, enabling it to extend and retract to load and unload the tire 106. The extension and retraction of the support plate 203i can achieve the effect of installing and removing the tire 106, allowing the aircraft body 100 to quickly change to a tire 106 type suitable for the current landing environment according to the actual situation.

[0046] Specifically, the outer surface of the limiting post 203g slides in contact with the inner wall of the arc groove 203f, and the outer surface of the sliding rod 203h slides in contact with the inner wall of the star-shaped guide rail 203b.

[0047] Preferably, the outer surface of the support plate 203i contacts the inner surface of the tire 106, and the worm gear 203e is rotated and sleeved on the outer surface of the positioning post 203j.

[0048] In use, manually rotating the worm 203d causes the worm wheel 203e to rotate, and the arc groove 203f moves accordingly, so that the limiting post 203g slides along the inner wall of the arc groove 203f, causing the sliding rod 203h to move inward. As the sliding rod 203h moves, the support plate 203i gradually detaches from the currently installed tire 106. At this time, the old tire 106 can be easily removed. After the new tire 106 is fitted onto the outside of the support plate 203i, the direction of the worm 203d is reversed, causing the worm wheel 203e to rotate in the opposite direction. Through the cooperation of the arc groove 203f and the limiting post 203g, the sliding rod 203h is pushed back to its original position, so that the support plate 203i can firmly support and fix the new tire 106.

[0049] In summary, by disassembling and assembling component 203, operators can quickly adjust the type of tires 106 according to different landing environments of the aircraft body 100. Whether performing tasks such as environmental monitoring, geographic mapping or emergency rescue, the tires 106 of the aircraft body 100 can be replaced in a short time, thereby greatly improving the adaptability and mission execution flexibility of the aircraft body 100.
