Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a quick-replacement rotor structure of an unmanned aerial vehicle. Background Art

[0002] Unmanned aerial vehicle, or UAV for short, is a non-manned aerial vehicle that uses advanced radio remote control technology and built-in program control devices for autonomous or remote control. UAVs have a wide range of applications and can be roughly divided into two categories: military and civilian.

[0003] Most existing drones use multi-rotor mechanisms. When flying, their rotors are easily damaged by collisions with the external environment, resulting in poor flight performance. The rotors need to be replaced, but the rotors are generally integrated with the fuselage mounting frame, making it impossible to quickly disassemble and replace the rotors, affecting their efficiency.

[0004] The rotor and the fuselage mounting frame are often connected in an integrated manner. The rotor is tightly integrated with the fuselage mounting frame of the drone, which limits the ability to quickly disassemble and replace the rotor. Once the rotor is damaged, the entire drone may need to be sent back to the maintenance center for a long period of maintenance, which brings great inconvenience. Although the rotors and fuselages of some drones can be disassembled, when replacing the rotors, the operator must carry the corresponding disassembly tools to complete the disassembly and assembly work. This not only increases the complexity and time cost of the operation, but also there are certain safety hazards when using professional tools for rotor replacement. If not used correctly, the operator may damage the rotor, fuselage and other components, and may even cause self-injury, affecting the efficiency of the drone.

[0005] Therefore, those skilled in the art provide a method for quickly replacing a rotor structure of a drone to solve the problems raised in the above background technology. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings existing in the prior art and to propose a UAV rotor structure for quick replacement. By moving the adjusting ring, the limit block is moved inside the rotating block, thereby releasing the lock on the rotating shaft, and then the rotating shaft is made to slide inside the rotating block, thereby realizing the quick replacement of the UAV rotor. No special tools are required during the replacement process, and the disassembly and assembly of the rotor can be completed only by manual operation, which reduces the difficulty of operation and improves efficiency.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A drone quick-change rotor structure comprises a drone body, two brackets are fixedly provided on both sides of the drone body, driving devices are fixedly provided on opposite sides of four brackets, rotating blocks are rotatably provided on the upper ends of the four driving devices, two springs are fixedly provided inside the four rotating blocks, limiting blocks are fixedly provided at the lower ends of the eight springs, and adjusting rings are slidably provided on the outside of the four rotating blocks;

[0009] The four rotating blocks are each provided with a rotating shaft inside, two fixed blocks are each fixedly provided outside the four rotating shafts, and limiting holes are each provided inside the eight fixed blocks;

[0010] Through the above technical solution, the rotating shaft is slid into the rotating block, and the fixed block outside it will slide inside the rotating block synchronously. Then, the rotating shaft is rotated inside the rotating block, so that the fixed block squeezes the limit block, causing the limit block to be forced to squeeze the spring at its upper end, so that the limit block slides into the limit hole opened inside the fixed block, thereby realizing the fixing operation of the rotating shaft, making the rotor replacement extremely quick and without the need for additional tools.

[0011] Furthermore, the exteriors of the eight fixed blocks are respectively slidably arranged inside the four rotating blocks, and the exteriors of the eight limiting blocks are respectively clamped and arranged inside the eight limiting holes;

[0012] Through the above technical solution, when the fixed block slides to a suitable position inside the rotating block, the limit block inside the rotating block will be snapped into the inside of the limit block, thereby achieving the fixing operation of the rotor.

[0013] Furthermore, four propellers are fixedly arranged on the upper ends of the four rotating shafts, and two supporting legs are fixedly arranged on the lower end of the drone body;

[0014] Through the above technical solution, when the rotating shaft rotates, it will drive the propeller outside it to rotate synchronously, and the support legs provide stable support for the drone on the ground.

[0015] Furthermore, the insides of the four adjustment rings are fixedly arranged on opposite sides of the eight limit blocks, and the outsides of the eight limit blocks are slidably arranged inside the four rotating blocks.

[0016] Through the above technical solution, when the adjusting block moves, it will drive the outer part of the limiting block to slide inside the rotating block, thereby realizing the rapid replacement operation of the UAV rotor.

[0017] Furthermore, two slots are provided inside the four rotating blocks, and the exteriors of the eight fixed blocks are slidably disposed inside the eight slots respectively;

[0018] Through the above technical solution, when installing, first align the fixed block with the slot inside the rotating block, and then insert it, so the whole installation process is relatively convenient.

[0019] Furthermore, an adjustment block is rotatably provided at the lower end of the drone body, and a camera is rotatably provided inside the adjustment block;

[0020] Through the above technical solution, the camera can be adjusted at multiple angles through the adjustment block to meet different shooting requirements, thereby improving the application flexibility of the drone.

[0021] Furthermore, two anti-sliding blocks are fixedly provided at the lower ends of the two supporting legs, and the four anti-sliding blocks are all made of rubber material;

[0022] Through the above technical solution, the anti-sliding block at the lower end of the supporting leg is made of rubber material to increase the friction with the ground, thereby improving the stability of the drone.

[0023] The utility model has the following beneficial effects:

[0024] 1. The utility model proposes a quick-change rotor structure for a UAV. When the rotor needs to be installed, align the fixed block on the rotating shaft with the slot in the rotating block and insert it. When the fixed block reaches the appropriate position, rotate the fixed block inside the rotating block. As the fixed block rotates, the limit block is squeezed and slides upward. Then, the spring pushes the limit block to move so that it is embedded in the limit hole in the fixed block, thereby fixing the rotor. The operation is convenient, thereby improving the replacement efficiency. 2. The utility model proposes a quick-change rotor structure for a UAV. When the rotor needs to be replaced, slide the adjustment ring outside the rotating block. The adjustment ring will drive the limit block connected to it to move synchronously, so that the limit block gradually moves out of the limit hole, and then rotate the rotating shaft. At this time, the rotating shaft can be taken out of the rotating block. The entire installation process does not require any tools and can be completed manually, simplifying the operation steps.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-4 , an embodiment provided by the utility model:

[0033] A drone quick-change rotor structure comprises a drone body 1, two brackets 7 are fixedly arranged on both sides of the drone body 1, driving devices 2 are fixedly arranged on opposite sides of four brackets 7, rotating blocks 4 are rotatably arranged on the upper ends of the four driving devices 2, two springs 12 are fixedly arranged inside the four rotating blocks 4, and limited blocks 16 are fixedly arranged at the lower ends of the eight springs 12, and adjusting rings 6 are slidably arranged on the outside of the four rotating blocks 4, rotating shafts 5 are arranged inside the four rotating blocks 4, and two fixed blocks 14 are fixedly arranged on the outside of the four rotating shafts 5, and eight fixed The fixed blocks 14 are provided with limit holes 13 inside, the eight fixed blocks 14 are slidably arranged outside the four rotating blocks 4, the eight limit blocks 16 are respectively clamped inside the eight limit holes 13, the four rotating shafts 5 are fixedly provided with four propellers 3 on the upper ends, the four adjusting rings 6 are respectively fixed on the opposite sides of the eight limit blocks 16, the eight limit blocks 16 are respectively slidably arranged inside the four rotating blocks 4, the four rotating blocks 4 are provided with two slots 15 inside, and the eight fixed blocks 14 are respectively slidably arranged inside the eight slots 15;

[0034] During the installation of the rotor, the fixed block 14 at the end of the rotating shaft 5 must first be accurately aligned with the slot 15 located in the rotating block 4, and then it must be smoothly inserted until the fixed block 14 reaches its predetermined position. At this time, the fixed block 14 is rotated inside the rotating block 4. When the fixed block 14 contacts the limit block 16, the limit block 16 is forced to slide upward inside the rotating block 4 and squeeze the spring 12, causing the spring 12 to contract inside the rotating block 4. Once the fixed block 14 is rotated to the correct position, the spring 12 moves downward until it is accurately embedded in the limit hole 13 on the fixed block 14, thereby forming a firm lock. Then the driving device 2 on the bracket 7 drives the rotating block 4 and the rotating shaft. 5 and the propeller 3 rotate, thereby generating lift and thrust to achieve flight control of the drone. When replacing the rotor, first slide the adjusting ring 6 outside the rotating block 4 to move the limit block 16 connected to the adjusting ring 6, so that the limit block 16 is gradually separated from the originally embedded limit hole 13. As the limit block 16 is withdrawn, the lock originally applied to the rotating shaft 5 is released. Then, by rotating the rotating shaft 5, since the limit mechanism has been effectively released, the rotating shaft 5 can be smoothly separated from the rotating block 4 and disassembled together with the rotor thereon. The whole process does not require any special tools, which not only simplifies the replacement process, but also reduces the technical threshold of operation, while also improving the user's operating experience and maintenance efficiency.

[0035] An adjusting block 11 is rotatably provided at the lower end of the drone body 1, and a camera 10 is rotatably provided inside the adjusting block 11. By rotating the adjusting block 11, the shooting angle of the camera 10 can be changed, and all-round angle adjustment can be achieved to meet different shooting and monitoring needs, thereby enhancing the application flexibility of the drone. Two supporting legs 9 are fixedly provided at the lower end of the drone body 1, and two anti-sliding blocks 8 are fixedly provided at the lower ends of the two supporting legs 9. The four anti-sliding blocks 8 are all made of rubber material. The drone body 1 is stably placed on the ground through the supporting legs 9. The anti-sliding blocks 8 at the lower ends of the supporting legs 9 provide stable support when the drone lands, and the rubber material can increase the friction with the ground, thereby improving the stability and safety of the drone.

[0036] Working principle: When assembling the rotor, the fixing block 14 at the lower end of the rotating shaft 5 is inserted into the slot 15, and then the rotating shaft 5 is rotated to make the fixing block 14 reach the preset position. When the fixing block 14 meets the limit block 16, the limit block 16 will be pushed and moved upward. When the fixing block 14 is rotated into place, the spring 12 rebounds, prompting the limit block 16 to be embedded in the limit hole 13, thereby forming a stable lock. If the rotor needs to be replaced, the limit block 16 connected to the adjusting ring 6 is linked to slide on the outside of the rotating block 4, so that it is gradually withdrawn from the limit hole 13. As the limit block 16 rises, the locking state originally implemented on the rotating shaft 5 is released. At this time, only the rotating shaft 5 needs to be rotated to separate the rotating shaft 5 from the rotating block 4 and remove the rotor together. The entire disassembly and assembly process does not require the intervention of any special tools, which simplifies the operation process, reduces the difficulty of operation, and at the same time improves the replacement efficiency.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
