[0026] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the present invention and does not strictly limit the scope of protection specifically claimed by the present invention.

[0027] like Figure 1 and Figure 5 As shown, a foldable-wing drone includes a body 1, with fixing frames 2 provided at each corner of the body 1, each of which is equipped with a vertically distributed control component 3, and a wing panel 4 connected to the fixing frame 2 via the control component 3, and the control component 3 is used to control and limit the rotation angle of the wing panel 4;

[0028] The control assembly 3 includes an operating rod 301 , a movable plate 302 and a limit block 303 . The operating rod 301 is connected to the limit block 303 via the movable plate 302 , and when the operating rod 301 moves, the limit block 303 moves along with the operating rod 301 .

[0029] In this embodiment, when the wings of the drone are to be folded, the operating rod 301 in the control assembly 3 is pressed, so that the operating rod 301 moves downward along the movable through hole 202, thereby driving the movable plate 302 below the operating rod 301 to move downward along the cylindrical groove 203. As the movable plate 302 moves downward, the limit block 303 on one side of the movable plate 302 moves downward along the rectangular through hole 204, and the movable plate 302 squeezes the return spring 304 below, while the other end of the limit block 303 moves along the limit slot. 402 moves downward, and stops when the limit block 303 moves downward into the rectangular groove 205. At this time, the propeller and the wing panel 4 are rotated around the fixed axis 201. When rotated to a suitable angle, the pressed operating rod 301 is released. Due to the elastic characteristics of the return spring 304, the limit block 303, the movable plate 302 and the operating rod 301 move upward, so that the limit block 303 moves upward along the limit slot 402, which can fix the folded wing panel 4 and the propeller, thereby completing a series of tasks.

[0030] like Figure 3 As shown, the movable plate 302 is provided at the lower end of the operating rod 301, and the limiting block 303 is provided on the side ring surface of the movable plate 302;

[0031] A return spring 304 is fixedly connected to the bottom of the movable plate 302 , and the return spring 304 is fixedly connected to the fixing frame 2 .

[0032] In the above method, when the wings of the drone are ready to be folded, the operating lever 301 in the control component 3 is pressed to move the operating lever 301 downward, thereby driving the movable plate 302 below the operating lever 301 to move downward. As the movable plate 302 moves downward, the limit block 303 on one side of the movable plate 302 moves downward, and the movable plate 302 squeezes the return spring 304 below.

[0033] like Figure 3 and Figure 4 As shown, a cylindrical groove 203 is opened inside the fixing frame 2, a movable through hole 202 is opened above the cylindrical groove 203, a rectangular through hole 204 is opened on one side of the cylindrical groove 203, and a rectangular groove 205 is opened below the rectangular through hole 204;

[0034] The rectangular through hole 204 and the rectangular groove 205 are communicated with the cylindrical groove 203 .

[0035] like Figure 3 and Figure 4 As shown, the moving plate 302 and the return spring 304 are both disposed in the cylindrical groove 203 , and the operating rod 301 passes upward through the moving through hole 202 ;

[0036] The stop block 303 passes through the rectangular through hole 204 and moves up and down in the cavity of the rectangular through hole 204. When the stop block 303 moves down, the stop block 303 fits in the interior of the rectangular groove 205.

[0037] In the above method, when the operating rod 301 is pressed, the operating rod 301 moves downward along the moving through hole 202, thereby driving the moving plate 302 below the operating rod 301 to move downward along the cylindrical groove 203. As the moving plate 302 moves downward, the limit block 303 on one side of the moving plate 302 moves downward along the rectangular through hole 204, and the moving plate 302 squeezes the return spring 304 below, and stops when the limit block 303 moves downward into the rectangular groove 205.

[0038] like Figure 3 As shown, the fixing frame 2 is composed of two upper and lower clamping plates facing each other, and the empty slot formed between the two clamping plates is used to install the wing panel 4. A fixed shaft 201 is provided in the empty slot of the fixing frame 2.

[0039] like Figure 2 and Figure 3As shown, a rotating through hole 401 matching the fixed shaft 201 is opened at one end of the wing plate 4, and multiple groups of limit slots 402 are opened on the outer ring side of the wing plate 4 that matches the fixing frame 2, and the multiple groups of limit slots 402 respectively match the limit blocks 303.

[0040] In the above method, when the limit block 303 in the control component 3 is disengaged from the limit slot 402, the propeller and the wing panel 4 are rotated around the fixed axis 201. When rotated to a suitable angle, the operating lever 301 in the control component 3 is released, so that the limit block 303 can move upward under the action of the return spring 304 and enter the limit slot 402, thereby fixing the position of the propeller and the wing panel 4 after rotating around the fixed axis 201.

[0041] The multiple sets of limit slots 402 can adjust the angle of the drone's wings according to the flight environment when the drone's wings are flying, thereby enabling the drone to perform flight missions faster and greatly improving work efficiency.

[0042] The working principle of the utility model is as follows: when the wings of the drone are to be folded, the operating rod 301 in the control assembly 3 is pressed, so that the operating rod 301 moves downward along the moving through hole 202, thereby driving the moving plate 302 below the operating rod 301 to move downward along the cylindrical groove 203. As the moving plate 302 moves downward, the limit block 303 on one side of the moving plate 302 moves downward along the rectangular through hole 204, and the moving plate 302 squeezes the return spring 304 below. At the same time, the other end of the limit block 303 moves along the limit card The slot 402 moves downward, and the limit block 303 stops when it moves downward into the rectangular groove 205. At this time, the propeller and the wing panel 4 are rotated around the fixed axis 201. When it is rotated to a suitable angle, the pressed operating rod 301 is released. Due to the elastic characteristics of the return spring 304, the limit block 303, the movable plate 302 and the operating rod 301 move upward, so that the limit block 303 moves upward along the limit slot 402, which can fix the folded wing panel 4 and the propeller, thereby completing a series of tasks.

[0043] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
