[0033] The connecting assembly includes a connecting frame 4 and two side frames 30. The connecting frame 4 is fixedly connected to the top of the outer wall of the drone body 3. The two side frames 30 are respectively fixedly connected to the two sides of the outer wall of the drone body 3. The ends of the connecting frame 4 and the two side frames 30 away from the drone body 3 are fixedly connected to the lower end of the main wing 5. Specifically, by setting the connecting frame 4 and the side frames 30, it is convenient to support and fix the main wing 5.

[0034] The driving mechanism includes a mounting block 16, which is fixedly connected to the inner front end of the aileron block 7, and a motor 15 is fixedly installed at the rear end of the mounting block 16, the motor 15 is parallel to the aileron piece 6, and a stud 9 is fixedly connected to the output shaft end of the motor 15, and the end of the stud 9 away from the motor 15 is rotatably connected to a fixed block 8, the fixed block 8 is fixedly connected to the inner wall of the aileron block 7 near the rear edge, and a sliding mechanism is provided between the stud 9 and the aileron piece 6.

[0035] The sliding mechanism includes a connecting block 12 and a sliding groove 24. The connecting block 12 is threadedly sleeved on the outer wall of the stud 9 near the front edge, and a slider 27 is fixedly connected to the middle of the upper end of the connecting block 12. The sliding groove 24 passes through the inner top of the aileron block 7 corresponding to the slider 27. The slider 27 and the sliding groove 24 are slidably matched, and the upper end of the slider 27 is fixedly connected to the lower end of the aileron piece 6.

[0036] A concave block 11 is fixedly connected to the upper end of the square groove 28 corresponding to the slide groove 24, the front end of the concave block 11 is fixedly connected to the front end of the square groove 28, and the rear end of the concave block 11 is flush with the rear end of the fixed block 8, and a concave groove 26 is provided on the inner wall of the aileron piece 6 corresponding to the concave block 11, and the concave block 11 and the concave groove 26 are slidably matched; specifically, by providing the concave block 11, when the aileron piece 6 slides on the square groove 28, it will slide on the outside of the concave block 11, and the concave block 11 is always in a fixed state with the square groove 28 and the aileron block 7, and the concave block 11 can always block the slide groove 24, so as to prevent a large amount of wind from entering the interior of the aileron block 7 along the slide groove 24, and to prevent external impurities from entering the interior of the aileron block 7 to avoid affecting the flight.

[0037] In this embodiment, first, the aileron block 7 and the aileron piece 6 form the aileron structure of the drone body 3. The rotating shaft 25 can be connected to the driving end inside the drone body 3, so that when the drone body 3 is flying, the rotating shaft 25 can be controlled by the remote control to rotate, which will drive the aileron block 7 to rotate in the concave groove 29 on the main wing 5. When the aileron block 7 rotates upward or downward, the aileron block 7 can drive the aileron piece 6 and the internal structure of the aileron block 7 to rotate together. At the same time, start the motor 15 (the remote control can be set to be electrically connected to the motor 15), then the motor 15 can drive the stud 9 to rotate on the fixed block 8, the stud 9 can drive the connecting block 12 to move backward away from the motor 15, the connecting block 12 can drive the slider 27 to slide in the slide groove 24, and the slider 27 can drive the aileron piece 6 to slide outward on the square groove 28 on the aileron block 7, thereby increasing the contact area between the aileron structure and the wind. The aileron structure's aerodynamic force is generated by its interaction with the airflow. When the aileron structure deflects, the direction and speed of the airflow are changed, thereby generating lift and torque. At this time, a larger aileron structure can have a larger surface area in contact with the airflow, so at the same deflection angle, it can generate a greater aerodynamic force. This enables the aileron structure to provide a stronger reaction force when the wind becomes stronger and resist wind disturbances. As a result, when flying in windy weather, the steering of the drone body 3 will increase sensitivity, thereby improving the flight experience.

[0038] It should be noted that, in normal weather, when the flap piece 6 does not need to slide outward, the motor 15 can be controlled to drive the stud 9 to reverse, so that the flap piece 6 will slide on the square groove 28 to return to its original position.

[0039] Example 2: Please refer to Figure 2-Figure 10 The present embodiment further explains the first embodiment. The blocking mechanism in the figure includes an L-shaped groove 21, which is opened at the upper edge of the front end of the concave groove 29, and the inner wall of the L-shaped groove 21 is provided with a plurality of evenly distributed cylindrical grooves 18, and connecting columns 20 are slidably inserted into the interior of the plurality of cylindrical grooves 18, and the upper ends of the plurality of connecting columns 20 are fixedly connected with a splicing block 22, and the lower ends of the plurality of connecting columns 20 are respectively fixedly connected with the inner bottom ends of the plurality of cylindrical grooves 18 with springs 19, and a rubber bag 23 is fixedly connected between the rear end of the splicing block 22 and the upper front end of the aileron block 7, and an inflation mechanism is provided between the rubber bag 23 and the aileron block 7.

[0040] The inflation mechanism includes a plurality of evenly distributed holes and grooves 17 and a plurality of evenly distributed connecting tubes 14, the plurality of connecting tubes 14 are all parallel to the aileron piece 6, and one end of the plurality of connecting tubes 14 are all connected to the inner front end corresponding to the rubber bag 23 of the aileron block 7, and the inner walls of the plurality of connecting tubes 14 are all fitted with rubber plugs 10, the rear ends of the plurality of rubber plugs 10 are all fixedly connected with connecting rods 13, the rear ends of the plurality of connecting rods 13 are all fixedly connected to the front end of the connecting block 12 near the upper edge, and a plurality of holes and grooves 17 are respectively opened on the outer wall of the rubber plug 10 corresponding to the plurality of connecting tubes 14.

[0041] In the present embodiment, when the connecting block 12 moves away from the motor 15, the connecting block 12 will also drive the multiple connecting rods 13 to move outward in the multiple connecting tubes 14 respectively. The multiple connecting rods 13 can drive the multiple rubber plugs 10 to slide outward in the multiple connecting tubes 14 respectively. Then, the rubber bag 23 can be evacuated through the hole groove 17, and the rubber bag 23 can gradually shrink. At this time, it will not affect the upward rotation of the aileron block 7, and the aileron block 7 will drive the rubber bag 23 to rotate together. The rubber bag 23 is a flexible, thin-walled and deformable material. The rubber bag 23 will then drive the splicing block 22 to slide downward on the L-shaped groove 21, and the splicing block 22 will drive the multiple connecting columns 20 to slide downward in the multiple columnar grooves 18 respectively and squeeze the spring 19. When the multiple rubber plugs 10 slide away from the multiple connecting tubes 14 respectively, the rubber bag 23 can be completely squeezed and shrunken by the aileron block 7, and the aileron block 7 can also rotate upward to the maximum distance.

[0042] When the connecting column 20 moves closer to the motor 15, the multiple connecting rods 13 will drive the multiple rubber plugs 10 to be inserted into the multiple connecting tubes 14 respectively, so as to continuously inflate the rubber bag 23, and the rubber bag 23 will continue to expand. At this time, when the aileron block 7 rotates downward to be flush with the main wing 5, the rubber bag 23 will be inflated to the most inflated state, sealing the upper gap between the aileron block 7 and the concave groove 29 (foreign objects are generally easy to get stuck in the upper gap between the aileron block 7 and the concave groove 29 from top to bottom, while the lower gap is generally not easy to get stuck in foreign objects). When the aileron block 7 rotates downward, it will pull the rubber bag 23, and the rubber bag 23 will drive the splicing block 22 to move upward, and the splicing block 22 will drive the multiple connecting columns 20 to slide upward in the multiple columnar grooves 18 and stretch the spring 19.

[0043] It should be noted that the rubber bag 23 is always in the upper gap between the aileron block 7 and the concave groove 29, so as to prevent foreign objects from getting stuck and affecting the rotation of the aileron block 7. The rubber bag 23 will also shrink as the aileron block 7 rotates upward, and will be stretched and deformed as the aileron block 7 rotates downward, and will not affect the rotation of the aileron block 7.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
