[0009] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0010] Please refer to Figures 1 to 3 , an arm disassembly and assembly structure, comprising a casing 2, an arm rod 1 and a motor 3, wherein the motor 3 is installed at one end of the arm rod 1, the casing 2 is provided with a plug hole 21, and the other end of the arm rod 1 is provided with a plug portion 11, and the plug portion 11 is used to be plugged into the plug hole 21; the plug portion 11 is provided with a first electrical connector 4 and a fastening portion 111, the first electrical connector 4 is electrically connected to the motor 3, and a second electrical connector 5 is provided in the plug hole 21, and the second electrical connector 5 is used to be electrically connected to the first electrical connector 4; a fastening hole 22 and a fastener are provided outside the casing 2, and when the plug portion 11 is plugged into the plug hole 21, the fastening hole 22 is aligned with the fastening portion 111, and the fastener is used to penetrate the fastening hole 22 and be connected to the fastening portion 111.

[0011] From the above description, it can be seen that the beneficial effects of the present invention are: through the cooperation of the plug-in part 11 and the plug-in hole 21, the arm and the casing 2 can be quickly plugged in; the direct docking of the first electrical connector 4 and the second electrical connector 5 ensures the instant conduction between the arm motor 3 and the control circuit, eliminating the need for additional wiring steps; after plugging in, the fasteners penetrate the fastening holes 22 and the fastening part 111 to lock them, thereby making up for the lack of structural strength of the pure plug-in structure and enhancing the arm's anti-displacement ability in a high vibration environment; the plug-in structure makes the arm an independent module, which is convenient for mass production, maintenance, replacement or upgrading.

[0012] Furthermore, an indicator light structure 6 is provided on the arm 1 , and the indicator light structure 6 is electrically connected to the first electrical connector 4 .

[0013] From the above description, it can be seen that the indicator light is directly related to the status of the electrical connector. When the arm is installed in place and the electrical signal is conducted, the indicator light will light up, and the user can intuitively judge whether the installation is successful, reducing the risk of misoperation; if the indicator light is not on, the user can quickly check the arm plug-in or circuit connection problems, shortening the maintenance time.

[0014] Furthermore, the indicator light structure 6 includes a lamp board 61, a lamp bead 62 and a light guide 63, the lamp board 61 is electrically connected to the first electrical connector 4, the lamp bead 62 is installed on the lamp board 61, one end of the light guide 63 is arranged opposite to the lamp bead 62, and the other end of the light guide 63 is exposed on the arm 1.

[0015] From the above description, it can be seen that the light guide 63 guides the light from the lamp bead 62 to the outside of the arm 1, so that the status can be clearly displayed even in a strong light environment, thereby improving the user interaction experience; the light board 61 and the light guide 63 are integrated inside the arm 1 to avoid the influence of the external indicator light on the aerodynamic shape of the arm and ensure flight stability.

[0016] Furthermore, the housing 2 is provided with a buckle 23 , and the arm 1 is provided with a slot 121 . When the plug-in portion 11 is plugged into the plug-in hole 21 , the buckle 23 is engaged with the slot 121 .

[0017] Furthermore, the housing 2 is provided with a slot 121 , and the arm 1 is provided with a buckle 23 . When the plug-in portion 11 is plugged into the plug-in hole 21 , the buckle 23 is engaged with the slot 121 .

[0018] From the above description, it can be seen that through the cooperation between the buckle 23 and the slot 121, the structural strength of the plug-in portion 11 and the plug-in hole 21 is further improved, and the position of the buckle 23 and the slot 121 can be set according to actual application requirements, which enriches the diversity of the structure and enhances the flexibility of the design.

[0019] Furthermore, the arm 1 is further provided with a limit baffle 12 . When the plug-in portion 11 is plugged into the plug-in hole 21 , the limit baffle 12 covers the plug-in hole 21 and contacts the outer wall of the housing 2 .

[0020] From the above description, it can be seen that the limit baffle 12 covers the plug-in hole 21, preventing dust and rain from entering the interior of the casing 2, thereby extending the life of the electrical connector; the baffle contacts the outer wall of the casing 2, limiting the insertion depth of the arm and avoiding structural damage caused by excessive insertion.

[0021] Furthermore, the plug-in portion 11 is provided with a first elastic clamping arm 112 and a second elastic clamping arm 113 extending in the same direction, an elastic clamping groove 114 is formed between the first elastic clamping arm 112 and the second elastic clamping arm 113 , and the first electrical connector 4 is installed in the elastic clamping groove 114 .

[0022] From the above description, it can be seen that the first elastic clamping arm 112 and the second elastic clamping arm 113 form an elastic clamp, applying continuous pressure to the electrical connector to offset the poor contact caused by flight vibration; the deformation of the elastic clamping groove 114 can cause micro-friction of the electrical connector contacts, remove the oxide layer or stains, and improve the reliability of signal transmission.

[0023] Furthermore, the motor 3 is electrically connected to the first electrical connector 4 via a conductive wire 31 .

[0024] As can be seen from the above description, the conductive wire 31 directly connects the motor 3 and the electrical connector, avoiding the lengthy external cables in traditional drones and reducing electromagnetic interference; and the modular cable design eliminates the need for rewiring when replacing the motor 3, reducing maintenance complexity.

[0025] Furthermore, the arm 1 is provided with a wire groove 15 , and the conductive wire 31 is installed in the wire groove 15 .
