[0002] The assembly and disassembly of drones is a crucial part of drone instruction, aiming to familiarize students with the drone's structure and improve their hands-on skills. Since drone instruction primarily targets teenagers, who may not yet be proficient in piloting drones, collisions can easily occur, causing damage. To reduce maintenance costs, the drones used in instruction are simple, modular products that are easy to assemble and disassemble. This not only facilitates learning about drone construction but also allows for easy replacement of faulty modules.

[0003] For the aforementioned modular drone products, the circuit board and power supply are typically located at the center of the fuselage. The fuselage extends in four directions to form arms, with motors installed at the ends of the arms. The circuit board and motors are connected via wiring harnesses. In educational detachable drones, the wiring harnesses are arranged along the arms and exposed outside the arms. To prevent collisions and interference between the propellers and the wiring harnesses during flight, they need to be temporarily bundled together with cable ties during product assembly. While cable ties provide temporary fixation, the excess length of the cable ties still needs to be cut off, making the process somewhat inconvenient. Utility Model Content

[0042] Please refer to the following: Figures 1 to 7 The structure and working principle of an easily detachable and assembleable teaching drone provided in the embodiments of this application will be described below.

[0043] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6This application provides an easily detachable and assembleable teaching drone, including a fuselage assembly 10, a battery 20, a control circuit board 30, a motor 40, and propellers 50. The fuselage assembly 10 includes a fuselage body 11 and a plurality of arms 12 arranged circumferentially along the fuselage body 11. Each arm 12 has a plurality of limiting members 14 spaced apart along its length. The limiting members 14 are rotatably connected to the arms 12, and a torsion spring 13 is connected between the rotation axis of the limiting member 14 and the arm 12. The torsion spring 13 is configured with a preload force to cause the limiting member 14 to abut against the arm 12. When the limiting member 14 abuts against the arm 12, the limiting member 14 and the arm 12... The space is enclosed to form a wiring channel; the battery 20 is detachably mounted on the main body 11; the control circuit board 30 is mounted on the main body 11 and electrically connected to the battery 20; multiple motors 40 are correspondingly mounted on the end of the arm 12 away from the main body 11, the motors 40 are detachably connected to the arm 12, and the motors 40 are electrically connected to the control circuit board 30 through a wiring harness 41, which is threaded through the wiring channel; multiple blades 50 are correspondingly mounted on the shaft of the motor 40.

[0044] Compared with the prior art, the beneficial effects of the easily detachable and assembleable teaching drone provided in this application embodiment are:

[0045] This application provides an easily detachable and assembleable teaching drone, comprising a fuselage assembly 10, a battery 20, a control circuit board 30, a motor 40, and propellers 50. The fuselage assembly 10 consists of a main body 11 and multiple arms 12. The battery 20 and the control circuit board 30 are respectively mounted on the main body 11. Each arm 12 is equipped with a motor 40 and a propeller 50 at its end. The battery 20 supplies power to the control circuit board 30 and the motors 40. The control circuit board 30 controls the rotation speed and direction of the motors 40 to complete the drone's flight maneuvers.

[0046] In this embodiment, the motor 40 and the control circuit board 30 are connected by an exposed wiring harness 41. The wiring harness 41 is laid along the arm 12, which allows trainees to intuitively understand the structure of the drone and facilitates wiring or disconnection during assembly and disassembly. A limiting member 14 on the arm 12 constrains the wiring harness 41. In its natural state, the limiting member 14 is tightly fastened to the arm 12 under the preload of the torsion spring 13, confining the wiring harness 41 within the wiring channel and preventing it from colliding with the propeller 50 during drone flight. When assembling the drone, trainees only need to rotate the limiting member 14 to overcome the preload to insert the wiring harness 41 into the wiring channel. When disassembling the drone, trainees can also release the constraint on the wiring harness 41 by rotating the limiting member 14. Compared with the existing method of using cable ties to bind the wiring harness 41, this method is more convenient and easier to assemble and disassemble. Furthermore, it eliminates the need to use scissors or other tools to cut the cable ties, resulting in higher safety and making it more suitable for drone teaching for teenagers.

There are no restrictions on the shape of the fuselage body 11 and the robotic arms 12; they can be shapes and structures found in existing technologies. Common shapes for the fuselage body 11 include circular and square, while the robotic arms 12 can be long and rod-shaped. The robotic arms 12 and the fuselage body 11 can be integrally formed and connected, or they can be detachably connected using screws or other connecting parts.

[0049] Multiple limiting members 14 are installed on the arm 12 along its length direction. The limiting members 14 are connected by... Figure 7 The torsion spring 13 shown is rotatably connected. The torsion spring 13 is an existing structure, sleeved on the rotating shaft of the limiting member 14, and has two mounting ends.
