[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a wing mounting structure that is easy to disassemble. Background Technology

[0002] A drone is an unmanned aerial vehicle that can be controlled via radio remote control and pre-programmed control devices, or operated fully or partially autonomously by an onboard computer. Currently, drones are widely used in aerial photography, agricultural monitoring, plant protection, personal photography, express delivery and logistics, disaster relief, wildlife observation, infectious disease monitoring, geographic mapping, news gathering, power facility inspection, disaster response, and film and television production, among other fields. However, existing drone wing mounting structures still have certain defects, such as:

[0003] The patent application CN202120410249.5, entitled "An Interwing Plug Mounting Structure for a Fixed-Wing Unmanned Aerial Vehicle," includes a UAV body connection end and a wing body. Support rods are symmetrically mounted inside the UAV body connection end. A drive structure is fixedly mounted on one side of the support rods, and a connecting structure is provided on one side of the drive structure. A fixing structure is fixedly mounted on the connecting structure. However, this structure requires workers to manually tighten screws during installation, which is cumbersome, inefficient, and fails to meet usage requirements. Therefore, a wing mounting structure that is easy to disassemble is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a wing mounting structure that is easy to disassemble, so as to solve the problem mentioned in the background art that the installation of existing UAV wings requires workers to manually tighten screws, which is cumbersome and inefficient.

[0005] To achieve the above objectives, this utility model provides the following technical solution: It includes a drone body and a connecting flange, with the connecting flange fixedly connected to the connecting arm of the drone body; a mating flange is provided on the outer end face of the connecting flange, and a cylindrical holder is fixedly connected to the outer end face of the connecting flange; a thread is provided on the outer wall surface of the cylindrical holder, and a limit slider is connected to the cylindrical holder via the thread; a through groove is provided on the cylindrical holder, and a steel ball is provided in the through groove; the length of the through groove is adapted to the diameter of the steel ball, and the steel ball is entirely embedded in the through groove, with its outer surface not exceeding the groove opening plane.

[0006] The above technical solution facilitates the rapid installation and removal of drone wings.

[0007] As a preferred embodiment of this utility model, the inner end face of the mating flange is fixedly connected to a plug-in post, and the outer wall surface of the plug-in post is provided with a groove corresponding to the steel ball.

[0008] The above technical solution facilitates a stable connection between the mating flange and the connecting flange.

[0009] As a preferred embodiment of this utility model, the cylindrical brackets are evenly distributed about the center of the connecting flange, and the plug-in posts are evenly distributed about the center of the mating flange.

[0010] The above technical solution facilitates uniform force distribution on the drone wings during installation, avoiding tilting or misalignment, and further improving the installation efficiency and stability of the drone wings. At the same time, the evenly distributed cylindrical brackets and plug-in posts can also enhance the connection strength between the wings and the drone body, ensuring the safety of the drone during flight.

[0011] As a preferred embodiment of this utility model, a limiting post is fixedly connected to the connecting flange, and a slot corresponding to the limiting post is provided on the mating flange.

[0012] The above technical solution facilitates precise docking between the connecting flange and the mating flange, improving the convenience and stability of installation. The matching design of the limiting post and the slot further enhances the stability and reliability of the wing installation structure, making the wing less prone to loosening or falling off after installation, thereby ensuring the flight safety and stability of the UAV.

[0013] As a preferred technical solution of this utility model, the outer end face of the docking flange is fixedly connected to an organic wing arm assembly.

[0014] The above technical solution is adopted to prevent the wing arm assembly from shaking or shifting during installation, and to ensure a stable connection between the wing arm assembly and the docking flange.

[0015] As a preferred technical solution of this utility model, the outer end face of the limiting slider is provided with anti-slip texture.

[0016] The above technical solution facilitates manual disassembly or installation of the wing mounting structure by operators, and increases the friction between the hand and the limiting slider through the anti-slip texture.

[0017] As a preferred embodiment of this utility model, a locking block is fixedly connected to the inner end face of the connecting flange, and the locking blocks are symmetrically arranged about the center of the connecting flange; a support rod is rotatably connected to the locking block, and the corresponding locking blocks on two adjacent connecting flanges are rotatably connected to both ends of the same support rod.

[0018] The above technical solution facilitates the improvement of the overall stability and load-bearing capacity of the wing mounting structure.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the device achieves a quick and stable connection between the wing arm assembly and the UAV body through structural design, effectively shortening the installation time, improving work efficiency, and the overall structure is simple, stable and easy to implement.

[0020] 1. When the workers are performing the installation work, they insert the limiting post on the connecting flange into the slot on the mating flange. During this process, the insert post enters the cylindrical bracket. As the insert post enters the cylindrical bracket, it lifts the steel ball until the steel ball falls into the groove corresponding to the outer wall of the insert post. At this time, the upper end of the steel ball is flush with the groove surface of the through groove of the cylindrical bracket.

[0021] 2. The length of the cylindrical holder slot is matched with the diameter of the steel ball. The steel ball is embedded in the slot as a whole, and its outer surface does not exceed the slot opening plane. The steel ball is confined in the slot along the extension direction of the slot and maintains a matching gap with the inner walls on both sides of the slot to ensure that its position in the slot is stable and can move along the slot direction.

[0022] 3. Then rotate the limiting slider so that the limiting slider moves to the right side of the cylindrical bracket along the external thread, so that the end of the limiting slider abuts against the upper surface of the steel ball, thereby achieving a fixed connection between the cylindrical bracket and the plug-in column.

[0023] 4. The fixed connection between the cylindrical bracket and the plug-in column, as well as the connection between the limiting column and the corresponding slot on the docking flange, makes the wing mounting structure more stable during connection, avoiding the overly complicated problems in the traditional wing mounting structure.

[0024] 5. At the same time, when it is necessary to disassemble the wing, simply rotate the limit slider in the opposite direction to move the limit slider along the external thread to the left side of the cylindrical bracket until the end is separated from the steel ball. The plug can then be easily pulled out of the cylindrical bracket, thereby realizing the rapid disassembly of the wing mounting structure, greatly improving the efficiency of wing installation and disassembly, and reducing maintenance costs.
