Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a UAV with a photovoltaic endurance function. Background Art

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or operated completely or intermittently autonomously by an onboard computer. Existing UAVs have different flight times due to different application industries, but the average flight time of a UAV is 20-40 minutes. The flight time of a UAV determines the execution time of the flight mission. How to improve the flight time of UAVs and ensure that UAVs can perform missions in a long-term manner is an important issue to be solved in the current field.

[0003] In the prior art, Chinese invention patent CN113320701B discloses a solar-powered high-endurance drone, comprising a medicine storage box, a body and a sprayer, wherein a medicine storage box is provided at one end of the body, and sprayers are provided at both ends of the medicine storage box, and fixing plates corresponding to the medicine storage box are provided at both ends of the body, and a power generation mechanism is provided at the other end of the body, which comprises a power generation component for generating electricity and a protective component for protecting the body, and a mixing mechanism is provided inside the medicine storage box, which comprises a spoiler component for mixing the medicine liquid stored in the medicine storage box and a pump component for driving the medicine liquid stored in the medicine storage box to flow; the present invention has a simple structure and is easy to use. When in use, the medicine liquid stored in the medicine storage box is fully mixed without dead angles through the linkage cooperation of the spoiler component and the pump component, thereby avoiding the unsatisfactory efficacy of the medicine liquid in the medicine storage box due to uneven mixing.

[0004] However, the power generation mechanism carried by the drone in this solution includes two solar panels in different directions, where the solar panels receive light at an inclined angle. However, when the panel is tilted as a whole, it is not conducive to the flight of the drone. The panel is subjected to greater air resistance during the flight of the drone, which will increase the load of the drone. In the case of wind interference, the airflow passing through the panel will also interfere with the movement of the drone.

[0009] Preferably, both ends of the bottom rotating rod, the middle rotating rod and the top rotating rod are provided with bevel gears, and the bevel gears are located inside the bottom fixing block, the middle fixing block and the top fixing block.

[0010] Preferably, the power mechanism includes several ear plates, and the ear plates are all located on the outside of the outer wall of the top plate.

[0012] Preferably, a hand-grip gap is provided on one side of the top mounting plate.

[0013] Preferably, both ends of the bottom mounting plate, the middle mounting plate and the top mounting plate are spliced ends, and an oblique air intake gap is formed between the spliced ends.

[0014] Preferably, a positive air intake gap is formed between the bottom mounting plate and the middle mounting plate, and a positive air intake gap is formed between the middle mounting plates and the top mounting plate.

[0015] Preferably, the bottom mounting tube, the middle mounting tube and the top mounting tube are each provided with a plurality of spring pieces, and one end of the spring piece is provided with a plurality of buckles.

[0017] Therefore, the present invention adopts a UAV with photovoltaic endurance function using the above structure, which has the following beneficial effects:

[0018] (1) The solar panels used in the drone of the present invention are multiple, wherein multiple bottom photovoltaic energy storage panels, middle photovoltaic energy storage panels, and top photovoltaic energy storage panels can be spliced to form an integral solar panel. The bottom photovoltaic energy storage panel, middle photovoltaic energy storage panel, and top photovoltaic energy storage panel can all be switched to a tilted state.

During flight of the drone, the gaps can provide flow space for part of the airflow, reduce the air resistance of the bottom photovoltaic energy storage panel, middle photovoltaic energy storage panel, and top photovoltaic energy storage panel during the forward movement, and are more conducive to the flight of the drone and reduce the load of the drone. In the case of wind interference, even if the drone is in a hovering state, the air permeable gaps can limit the impact on the entire body of the drone.

[0019] (2) The bottom photovoltaic energy storage panel, the middle photovoltaic energy storage panel and the top photovoltaic energy storage panel carried by the present invention are stored in a flat manner on the top of the drone body when the drone is closed. The overall endurance structure has little effect on the appearance of the drone, and the volume after storage has little effect on the portability of the drone, making the drone more stable during flight and achieving the significant effect of extending the endurance time. In the case of relatively harsh operating environment (such as high flight space restrictions or bad weather), the solar panel can be kept horizontal and its flight volume can be reduced to ensure that it can perform flight missions more reliably and reduce the many disadvantages caused by the solar panel body to the drone.

[0036] The interiors of the bottom mounting tube 5 , the middle mounting tube 6 and the top mounting tube 10 are all hollow structures.

[0037] Bevel gears 15 are provided at both ends of the bottom rotating rod 4 , the middle rotating rod 9 and the top rotating rod 13 . The bevel gears 15 are located inside the bottom fixing block 3 , the middle fixing block 8 and the top fixing block 12 .

[0038] The power mechanism includes several ear plates 16, which are all located on the outside of the outer wall of the top plate 1. A driving member 17 is provided at the bottom of the ear plate 16, and the driving member 17 is connected to the bottom of the driving shaft 18. The fan blades 19 are sleeved on the outside of the outer wall of the top of the driving shaft 18.

[0039] The energy storage structure includes several bottom installation plates 20, several middle installation plates 21, several top installation plates 22, several bottom photovoltaic energy storage panels 23, several middle photovoltaic energy storage panels 24 and several top photovoltaic energy storage panels 25. The bottom installation plate 20 is connected to the bottom photovoltaic energy storage panel 23, the middle installation plate 21 is connected to the middle photovoltaic energy storage panel 24, and the top installation plate 22 is connected to the top photovoltaic energy storage panel 25.

[0040] A hand gap is provided on one side of the top mounting plate 22 .

[0041] Both ends of the bottom mounting plate 20 , the middle mounting plate 21 and the top mounting plate 22 are splicing ends 26 , and an oblique air intake gap 27 is formed between the splicing ends 26 .

[0042] A positive air intake gap 28 is formed between the bottom mounting plate 20 and the middle mounting plate 21 , and a positive air intake gap 28 is formed between the middle mounting plates 21 and the top mounting plate 22 .

[0043] A plurality of spring pieces 29 are provided on each of the bottom mounting tube 5 , the middle mounting tube 6 and the top mounting tube 10 , and a plurality of buckles 30 are provided at one end of the spring piece 29 .

[0044] Shock absorbers 31 are installed at the four corners of the bottom end of the top plate 1 , and a plurality of pulleys 32 are provided at the bottom ends of the shock absorbers 31 .

[0045] Working principle: When the drone body 2 is in use, the user starts to rotate the top mounting tube 10 upward, and the top mounting tube 10 moves from the outside of the middle mounting tube 6. In the process of the top mounting tube 10 moving upward, the top support plate 11 moves upward, further driving the top fixing block 12 and the top rotating rod 13 to move upward. After moving a certain distance, the middle mounting tube 6 also moves upward on the outside of the bottom mounting tube 5, driving the middle support plate 7 and the middle fixing block 8 to move, and further driving the energy storage structure to move respectively. The energy storage structure can rotate on the rotating top rotating rod 13, the middle rotating rod 9 and the top rotating rod 13, thereby tilting the energy storage structure, making the energy storage structure in an inclined state, maintaining a state perpendicular to the solar energy to the greatest extent, and then absorbing the solar energy efficiently, so as to maximize the function of achieving endurance.

[0046] The interiors of the bottom mounting tube 5, the middle mounting tube 6, and the top mounting tube 10 are all hollow structures, which are used to reduce the weight of the bottom mounting tube 5, the middle mounting tube 6, and the top mounting tube 10, thereby reducing the load. The hand gap 14 is used to pull the top mounting tube 10.

[0047] The bottom rotating rod 4, the middle rotating rod 9 and the top rotating rod 13 can be rotated by the bevel gear 15. At the same time, the bottom rotating rod 4, the middle rotating rod 9 and the top rotating rod 13 can stop freely during rotation. The principle of their free stop can refer to the principle of the notebook shaft.

[0048] When the drone body 2 is flying, the energy storage mechanism provides electrical energy to the driving member 17, and then the driving member 17 starts to rotate, driving the driving shaft 18 to start rotating, and further rotating the fan blades 19, so that the drone body 2 can achieve the flight effect.

[0049] The top mounting plate 22, the middle mounting plate 21 and the bottom mounting plate 20 are distributed in a stepped manner under the pull of the top mounting tube 10 and the middle mounting tube 6. Then the user rotates the top photovoltaic energy storage panel 25 by hand to rotate the top photovoltaic energy storage panel 25. When one of the top mounting plates 22 is pulled, the top rotating rod 13, the middle rotating rod 9 and the bottom rotating rod 4 can be driven to rotate respectively through the cooperation of the bevel gears 15, thereby causing the top mounting plate 22, the middle mounting plate 21 and the bottom mounting plate 20 to rotate at an angle, thereby driving the bottom photovoltaic energy storage panel 23 and the middle photovoltaic energy storage panel 24 and the top photovoltaic energy storage panel 25 rotate. After the drone body 2 is used, it needs to be stored. At this time, the user presses the top mounting tube 10, and the top mounting tube 10 begins to descend and wraps around the outside of the middle mounting tube 6. Then, the user continues to press, and the middle mounting tube 6 begins to move downward. Then, the middle mounting tube 6 is inserted into the outside of the bottom mounting tube 5. At this time, the bottom ends of the middle support plate 7 and the top support plate 11 are in contact with the upper surface of the top plate 1, thereby completing the storage of the top photovoltaic energy storage panel 25, the middle photovoltaic energy storage panel 24, and the bottom photovoltaic energy storage panel 23, making it easier to store the drone body 2. The ends of the multiple bottom mounting plates 20, the multiple middle mounting plates 21, and the multiple top mounting plates 22 are set as splicing ends 26, and the splicing ends 26 are separated by oblique air intake gaps 27.

[0050] The oblique air intake gaps 27 formed between the spliced ends 26 facilitate air flow when the drone body 2 is in flight and the top photovoltaic energy storage panel 25, the middle photovoltaic energy storage panel 24, and the photovoltaic energy storage panel are tilted, thereby reducing the flight resistance of the drone body 2. Positive air intake gaps 28 are formed between the bottom mounting plate 20 and the middle mounting plate 21, and between the middle mounting plates 21 and the top mounting plate 22.

[0051] The positive short-term gap facilitates the passage of gas and reduces flight resistance. The bottom mounting tube 5, the middle mounting tube 6 and the top mounting tube 10 are respectively provided with a plurality of spring pieces 29, and one end of the plurality of spring pieces 29 is provided with a plurality of buckles 30.

[0052] When the middle mounting tube 6 and the top mounting tube 10 are stretched, the spring 29 pushes the block, allowing it to connect with the top mounting tube 10 and the middle mounting tube 6, respectively, thereby achieving a fixed support effect. Shock absorbers 31 are mounted at the four corners of the bottom end of the top plate 1, and the bottom ends of the shock absorbers 31 are equipped with several pulleys 32. The shock absorbers 31 are used to reduce vibration when the drone body 2 is stopped, and the pulleys 32 facilitate the sliding of the drone body 2.

[0053] Therefore, the present invention utilizes the aforementioned photovoltaic endurance drone to facilitate flight and reduce the drone's load. In the presence of wind interference, even when the drone is in a hovering state, the provision of ventilation gaps limits the impact on the entire drone, ensuring more reliable flight missions and reducing the many adverse effects of solar panels on the drone.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solutions of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
