[0002] A drone is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or operated autonomously by an onboard computer, either completely or intermittently. It is generally equipped with a camera, which allows the operator to clearly observe the drone's perspective.

[0003] A drone, as disclosed in Chinese Patent Publication No. CN221081444U, includes a drone frame. A mounting plate is provided on the lower outer surface of the drone frame. A first connecting plate is provided at the lower end of the mounting plate. A protective cover is provided on the outer wall of the lower outer surface of the first connecting plate. First grooves are formed on both sides of the upper outer surface of the first connecting plate. A telescopic rod is provided inside the first groove. A second connecting plate is provided on the lower outer surface of the telescopic rod. This drone, according to this utility model, features a protective cover that can shield against rain, providing waterproofing. Absorbent cotton absorbs water, preventing rainwater from flowing along the camera and affecting image quality. The camera height can be adjusted, and the first connecting plate and mounting plate can be easily and quickly assembled and disassembled. The operation is simple, facilitating the installation and disassembly of the protective cover with the camera, leading to better application prospects.

[0004] In the process of realizing this application, the inventors discovered that the technology has at least the following problems: the drone arm in the above technical solution adopts an integrated design, so the arm and the body are fixedly installed, which makes it inconvenient to store after use. Moreover, when storing, the protruding arm may be broken by external objects. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a folding assembly for a drone arm, comprising a fuselage, a base plate fixedly mounted on the bottom side of the fuselage, supports fixedly mounted on both sides of the base plate, a fixed shaft fixedly mounted inside the supports, a bushing sleeve sleeved on the outer side of the fixed shaft and located inside the fixed shaft, a self-locking assembly restricting the rotation of the bushing sleeve being provided inside the bushing sleeve, a folding arm fixedly mounted on the outer side of the bushing sleeve, a blade provided at the other end of the folding arm, and a support leg fixedly mounted on the bottom side of the other end of the folding arm for support.

[0006] As an optimization, the folding arm consists of a support frame and a support plate, with one end of the support plate hinged to the support frame, and the hinged end of the support plate also having a self-locking component.

[0007] As an optimization, a reinforcing plate is fixedly installed on one side of the support frame, and both the support frame and the support plate are made of lightweight carbon fiber material, thereby improving the strength of the support frame.

[0008] As an optimization, the self-locking assembly includes a toothed ring fixedly installed on the outside of the fixed shaft. The inside of the bushing is provided with an installation groove around the toothed ring array, and a self-locking component for limiting and locking the toothed ring is provided in the installation groove.

[0009] As an optimization, the self-locking component includes a fixed frame fixedly installed in the mounting groove, a sliding plate slidably connected inside the fixed frame, a locking head fixedly installed on the side of the sliding plate opposite to the locking ring, and the locking head slidably inserted into the fixed frame, and a spring fixedly installed between the sliding plate and the side wall of the fixed frame.

[0010] As an optimization, an electromagnet is fixedly installed on the bottom wall of the fixed frame, and a magnetic block is fixedly installed on the side of the slide plate opposite to the electromagnet.

[0011] As an optimization, the electromagnet is electrically connected to the internal power supply of the drone, and its power is switched on and off wirelessly.

[0012] The beneficial effects of this utility model are: This folding assembly for drone arms, when folded via the support frame and support plate, causes the locking head to rotate around the locking tooth ring, which in turn slides into the sliding plate under pressure. Then, the spring itself returns to its original position, thus not hindering normal folding and turning. This facilitates folding and storage and prevents accidental damage to the outward-protruding arms.

[0013] This folding assembly for drone arms works by activating an electromagnet, which repels a magnetic block and moves a sliding plate. This, in turn, secures the locking head between two teeth on the outside of the locking ring, thus enabling self-locking and limiting the rotation of the bushing. This ensures the stability of the folding arm after it is unfolded, thereby guaranteeing the stability of the drone during flight. Attached Figure Description

[0016] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-2 A folding assembly for a drone arm includes a body 1, a base plate 2 fixedly mounted on the bottom side of the body 1, supports 3 fixedly mounted on both sides of the base plate 2, a fixed shaft 4 fixedly mounted inside the supports 3, a bushing 5 sleeved on the outside of the fixed shaft 4 and located inside the fixed shaft 4, a self-locking assembly for restricting the rotation of the bushing 5 is provided inside the bushing 5, a folding arm fixedly mounted on the outside of the bushing 5, a blade 6 provided at the other end of the folding arm, and a support leg 7 fixedly mounted on the bottom side of the other end of the folding arm for support. Please see Figure 1-2 The folding arm consists of a support frame 8 and a support plate 9. One end of the support plate 9 is hinged to the support frame 8. The end of the support plate 9 that is hinged to the support frame 8 also has a self-locking component. By turning the support frame 8 around the fixed shaft 4, it can be close to the outside of the body 1. Then, by rotating the support plate 9 into the support frame 8, the arm can be folded for easy storage. Please see Figure 1-2 A reinforcing plate is fixedly installed on one side of the support frame 8. Both the support frame 8 and the support plate 9 are made of lightweight carbon fiber. The strength of the support frame 8 is improved by the reinforcing plate. The carbon fiber material has strength without being too heavy. Please see Figure 3-4The self-locking assembly includes a toothed ring 10 fixedly installed on the outside of the fixed shaft 4. The inside of the bushing 5 is provided with an array of mounting grooves around the toothed ring 10, and a self-locking component 11 for limiting and locking the toothed ring 10 is provided in the mounting groove. By locking the toothed ring 10 with the self-locking component 11, the rotation of the bushing 5 can be restricted, and the locking restriction can be performed after adjusting the angle of the folding arm. Please see Figure 3-4 The self-locking component 11 includes a fixed frame 12 fixedly installed in the mounting groove. A sliding plate 13 is slidably connected inside the fixed frame 12. A locking head 14 is fixedly installed on the side of the sliding plate 13 opposite to the locking tooth ring 10, and the locking head 14 is slidably inserted into the fixed frame 12. A spring 15 is fixedly installed between the sliding plate 13 and the side wall of the fixed frame 12. The spring 15 will drive the locking head 14 to insert between two adjacent locking teeth on the outside of the locking tooth ring 10 through its own elastic force, thereby playing a limiting role. Please see Figure 3-4 An electromagnet 16 is fixedly installed on the bottom wall of the fixed frame 12. A magnetic block 17 is fixedly installed on the side of the slide plate 13 opposite to the electromagnet 16. The electromagnet 16 is electrically connected to the internal power supply of the drone and is powered on and off wirelessly. When the electromagnet 16 is activated, it will generate magnetism, which will repel the magnetic block 17. Therefore, the slide plate 13 will be pushed to drive the locking head 14 into the two outer teeth of the locking ring 10, thus achieving the locking function.

[0019] When folding, rotate the support frame 8 close to the side of the body 1, and then rotate the support plate 9 into the support frame 8 to fold the arm for easy storage. When rotating, the locking head 14 will rotate around the locking tooth ring 10 and then slide into the slide plate 13 under pressure. Then, the spring 15 will return to its original position by its own elasticity, so as not to hinder normal folding. In use, simply pull out the support frame 8 and the support plate 9, and then energize the electromagnet 16 via wireless control. This will repel the magnetic block 17, causing the slide plate 13 to slide along the inner wall of the fixed frame 12. This will cause the locking head 14 to be stably locked in the two teeth on the outside of the locking ring 10, thus achieving a locking effect and stabilizing the unmanned flight.

[0020] In summary, when the folding assembly for the drone arm is folded via the support frame 8 and the support plate 9, the locking head 14 will rotate around the locking tooth ring 10, and then be pressed into the slide plate 13. It will then be reset by the elastic force of the spring 15, thus not hindering normal folding and thus facilitating folding and storage, and preventing accidental damage to the outward-extending arm.

[0021] By activating the electromagnet 16, the repulsive force repels the magnetic block 17, causing the slide plate 13 to move. This, in turn, stably locks the locking head 14 between the two teeth on the outside of the locking ring 10, thus enabling self-locking and restricting the rotation of the bushing 5. This ensures the stability of the folding arm after it is unfolded, thereby ensuring the stability of the drone during flight.
