Description

Technical Field

[0001] This application relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with folding arms. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously by an onboard computer, either completely or intermittently.

[0003] An existing patent (publication number: CN216140171U) discloses a folding arm for a drone, belonging to the field of drone assembly. The folding arm includes a first connecting arm, with toothed plates fixed to its left and right sides. A second connecting arm is located in front of the first connecting arm, with square holes on its left and right sides. Two hinge seats are fixed to the left and right sides of the second connecting arm in a symmetrical structure. A rotating shaft is fixed to the inner wall of each hinge seat. Torsion springs are fitted at the upper and lower ends of the rear rotating shaft. A retaining plate is rotatably connected to the outer surface of the rear rotating shaft, and a gear is rotatably connected to the outer surface of the front rotating shaft. By connecting the connecting block to the second connecting arm, the second connecting arm can be folded, thereby changing the size of the drone for easier storage and carrying. Inserting the connecting block into the second connecting arm and connecting it with a threaded rod improves the strength of the connection between the second connecting arm and the connecting block.

[0004] The aforementioned drone arm can change its length to facilitate storage and carrying, but it cannot protect the blades on the arm. During carrying and transfer, the blades are easily damaged, causing deformation. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a folding-arm drone, which has advantages such as good folding and protection, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a folding-arm drone, including a connecting base, a storage box fixedly connected to one side of the connecting base, an inner arm fixedly connected to one side of the connecting base, a rotating shaft rotatably connected to the other end of the inner arm, an outer arm fixedly connected to the outer surface of the rotating shaft, and a fan blade provided at the end of the outer arm away from the inner arm.

[0007] The outer arm is provided with a limiting component at one end near the inner arm. The limiting component includes a sleeve, which is fixedly connected to the end of the outer arm near the inner arm. A plug rod is slidably connected inside the sleeve. A spring is fixedly connected between the plug rod and the inner arm of the sleeve. A limiting hole is opened at the end of the inner arm away from the connecting seat, and the plug rod is inserted into the limiting hole.

[0008] The above solution, through the design of a folding arm structure with a storage box, allows the blades to be located inside the storage box after folding, effectively avoiding the risk of the blades being squeezed or collided with by external forces during carrying and transfer. This design not only protects the integrity of the blades, preventing deformation or damage, but also ensures the safety and stability of the drone in the folded state. The outer arm and inner arm are rotatably connected by a pivot, and with the insertion rod and spring design in the limiting component, the folding and unfolding operation of the arm becomes simple and quick, improving the convenience of operation. The magnet embedded in the bottom arm inside the storage box and the iron plate embedded in the bottom of the outer arm work together to provide additional fixing force after the arm is folded, effectively preventing the outer arm from being accidentally unfolded or loosened during carrying.

[0009] Furthermore, one end of the insertion rod is rounded.

[0010] The above solution, with the rounded corner at one end of the insertion rod, facilitates insertion of the insertion rod into the limiting hole.

[0011] Furthermore, the inner arm edge near the outer arm is rounded.

[0012] The above scheme and settings facilitate the compression of the rounded ends of the insertion rod.

[0013] Furthermore, a pull rod is fixedly connected to the outer surface of the insertion rod.

[0014] The above solution, with the addition of a lever, allows users to easily release the limit.

[0015] Furthermore, a magnet is fixedly embedded in the inner bottom arm of the storage box, and an iron sheet is fixedly embedded in the bottom of the outer arm at the end away from the connecting seat.

[0016] The above solution and setup can secure the outer arm after folding, preventing the blades from detaching from the storage box during transport.

[0017] Furthermore, a set of connection holes are provided on the surface of the connector.

[0018] The above solution, with its connection holes, facilitates connection to external devices.

[0019] Furthermore, the surfaces of both the outer arm and the inner wall are covered with a wear-resistant coating.

[0020] The above solution, through the application of a wear-resistant coating, can reduce frictional wear between the outer arm and the inner arm or other components during unfolding and folding, thereby extending the service life of the drone.

[0021] Furthermore, the radius of the storage box is greater than the length of the blade fan.

[0022] The above scheme and settings can achieve the purpose of protecting the blades.

[0023] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0024] This type of folding-arm drone features a folding arm structure with a storage box. When folded, the blades are housed inside the storage box, effectively preventing the blades from being squeezed or collided during transport and transfer. This design not only protects the integrity of the blades, preventing deformation or damage, but also ensures the safety and stability of the drone in its folded state. The outer and inner arms are connected by a pivot, and the insertion rod and spring design in the limiting component make the folding and unfolding of the arms simple and quick, improving operational convenience. The magnet embedded in the bottom arm inside the storage box works in conjunction with the iron plate embedded in the bottom of the outer arm to provide additional fixing force after the arm is folded, effectively preventing the outer arm from accidentally unfolding or loosening during transport.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a folding-arm drone includes a connecting base 1. A storage box 2 is fixedly connected to one side of the connecting base 1, and an inner arm 3 is fixedly connected to one side of the connecting base 1. A rotating shaft 4 is rotatably connected to the other end of the inner arm 3. An outer arm 5 is fixedly connected to the outer surface of the rotating shaft 4. A blade 6 is provided at the end of the outer arm 5 away from the inner arm 3. The rotatable connection between the outer arm 5 and the inner arm 3 enables the folding of the inner arm 3. A magnet 9 is fixedly embedded in the inner bottom arm of the storage box 2, and an iron plate 10 is fixedly embedded in the bottom of the end of the outer arm 5 away from the connecting base 1. With the above settings, the outer arm 5 can be fixed after folding, preventing the blade 6 from detaching from the storage box 2 during carrying.

[0034] Please see Figure 1 , Figure 2 and Figure 5 A limiting component 7 is provided at one end of the outer arm 5 near the inner arm 3. The limiting component 7 includes a sleeve 701, which is fixedly connected to the end of the outer arm 5 near the inner arm 3. An insert rod 702 is slidably connected inside the sleeve 701. A spring 703 is fixedly connected between the insert rod 702 and the inner arm 3 of the sleeve 701. A limiting hole 704 is opened at the end of the inner arm 3 away from the connecting seat 1. The insert rod 702 is inserted into the limiting hole 704. Through the above settings, the purpose of fixing the outer arm 5 can be achieved. One end of the insert rod 702 is rounded. The rounded corner of one end of the insert rod 702 makes it easy for the insert rod 702 to be inserted into the limiting hole 704.

[0035] Please see Figure 1 , Figure 3 and Figure 4 The inner arm 3 has a rounded corner at the inner edge of the arm closest to the outer arm 5. This design facilitates the compression of the rounded end of the insertion rod 702. A pull rod 8 is fixedly connected to the outer surface of the insertion rod 702. The pull rod 8 allows the user to release the limit. The radius of the storage box 2 is greater than the length of the blade fan 6. This design achieves the purpose of protecting the blade fan 6.

[0036] Please see Figure 1 , Figure 2 and Figure 3The surface of the connector 1 is provided with a set of connection holes 11. The connection holes 11 facilitate connection with the external body. The surfaces of the outer arm 5 and the inner wall are covered with a wear-resistant coating. The wear-resistant coating reduces frictional wear between the outer arm 5 and the inner arm 3 or other components during unfolding and folding, thus extending the service life of the drone.

[0037] This embodiment of a folding-arm drone features a folding arm structure with a storage box 2. After folding, the blades 6 are housed inside the storage box 2, effectively preventing the blades 6 from being squeezed or collided during transport and transfer. This design not only protects the integrity of the blades 6, preventing deformation or damage, but also ensures the safety and stability of the drone in the folded state. The outer arm 5 and inner arm 3 are rotatably connected by a pivot 4. Combined with the insertion rod 702 and spring 703 in the limiting component 7, the folding and unfolding of the arm becomes simple and quick, improving operational convenience. The magnet 9 embedded in the bottom arm of the storage box 2 and the iron plate 10 embedded in the bottom of the outer arm 5 work together to provide additional fixing force after the arm is folded, effectively preventing the outer arm 5 from accidentally unfolding or loosening during transport.

[0038] It should be noted that the folding-arm drone in this embodiment also has high reliability and durability. Key components such as the connecting seat 1, inner arm 3, and outer arm 5 are all made of high-strength, lightweight materials to ensure the stability and durability of the drone during flight. At the same time, through precise processing and assembly, the fit between the components is tight, reducing the possibility of loosening and wear. In addition, the wear-resistant coating not only reduces friction loss but also improves the corrosion resistance and anti-aging performance of the components, further extending the service life of the drone.

[0039] The working principle of the above embodiment is as follows: First, when the drone is in the folded state, the outer arm 5 is connected to the inner arm 3 through the pivot 4 and is kept in the unfolded position. The insertion rod 702 is kept inside the limiting hole 704 under the action of the spring 703, effectively preventing the outer wall from shaking during flight. When it is necessary to fold the drone, the user first pulls the insertion rod 702 outward through the pull rod 8 to overcome the elastic force of the spring 703, so that the insertion rod 702 is disengaged from the limiting hole 704. Then, the user folds the outer arm 5 towards the connecting seat 1, so that the outer arm 5 is close to the inner arm 3, shortening the overall length. After folding, the fan blade 6 can enter the interior of the storage box 2, and the bottom arm of the storage box 2... The embedded magnet 9 attracts the iron plate 10 embedded at the bottom of the outer arm 5, providing additional fixing force for the folded arm and preventing the outer arm 5 from accidentally unfolding or loosening during carrying. When the drone needs to be unfolded for flight, the outer arm 5 is opened and moved away from the storage box 2. The rounded corner design of the inner edge of the inner arm 3 will contact the rounded end of the insertion rod 702 and squeeze the insertion rod 702, causing the insertion rod 702 to slide along the inside of the sleeve 701. When the outer arm 5 is flipped into place, the insertion rod 702 will be aligned with the limiting hole 704 on the inner arm 3 and quickly inserted into the limiting hole 704 under the action of the spring 703, thus fixing the outer arm 5.
