[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, a folding mechanism of a drone with an interlocking function comprises an overall structure 1 and an auxiliary structure 2, wherein the auxiliary structure 2 is located at both sides of the bottom of the overall structure 1; the overall structure 1 comprises a casing 101, and the outer surfaces of both sides of the casing 101 are fixedly connected with a fixing frame 112 near the front side, and the inner surface of the fixing frame 112 is rotatably connected with a rotating shaft 104, the outer surface of the rotating shaft 104 is fixedly connected with a frame 103, and the top center of the frame 103 is fixedly connected with a wing 102, and a first bolt 114 is threadedly provided through the bottom of the rotating shaft 104, and the top and bottom front and rear positions of the outer surfaces of both sides of the casing 101 are fixedly connected with connecting blocks 105, the inner surface of the connecting block 105 is slidably connected with a connecting rod 106, and the outer surface of the connecting rod 106 is fixedly connected with a limiting member 107.

[0025] The effect achieved by the entire embodiment 1 is as follows: Figure 1 and Figure 2As shown, in the subsequent actual use, the frame 103 can be swung to between the two limit members 107 through the cooperation of the rotating shaft 104. After swinging, the first bolt 114 is screwed into the corresponding first threaded hole 113, so that the frame 103 can be stably located at an angle, which also indirectly ensures that the frame 103 can be stably located between the two limit members 107.

[0026] Embodiment 2, as Figure 1-Figure 4 As shown, the bottom of the rotating shaft 104 is located at the position of the first bolt 114 and is provided with a plurality of evenly distributed first threaded holes 113. The inner surface wall of the first threaded hole 113 is threadedly connected to the outer surface of the first bolt 114. The top end surface of the first bolt 114 is threadedly penetrated through the outer surface of the fixing frame 112. A compression spring 111 is provided on the opposite side of the connecting block 105 and the connecting rod 106. One end of the compression spring 111 is fixedly connected to the inner surface of the connecting block 105, and the other end of the compression spring 111 is fixedly connected to the outer surface of the connecting rod 106. Anti-skid pads 109 are fixedly connected at the inner top and inner bottom centers of the positioning member 107, blocks 110 are fixedly connected at both sides of the bottom of one of the limiting members 107, a second bolt 108 is threadedly penetrated on the outer surface of the limiting member 107 near the bottom, and the outer surface of the second bolt 108 is threadedly penetrated through the outer surface of the block 110, the auxiliary structure 2 includes a landing gear 201, a buffer pad 202 is fixedly connected at the bottom center of the landing gear 201, and the top surface of the landing gear 201 is fixedly connected to the bottom surface of the casing 101.

[0027] The effect achieved by the entire embodiment 2 is that the limiting member 107 can utilize the expansion force of the compression spring 111 to effectively apply force to the frame 103, and then increase the friction through the cooperation of the anti-slip pad 109 to play a role of preliminary restriction, and then through the cooperation of the second bolt 108 and the block 110, the frame 103 can be restricted for a secondary time. Then, the wing 102 is set on the frame 103. When the frame 103 is restricted to be stable and immovable, it is also indirectly prevented from shaking the wing 102, ensuring that it will not be damaged due to shaking.

[0028] Working principle: when folding is required, the user manually swings the frame 103 through the rotating shaft 104. After swinging to a certain position, the swinging user screws the first bolt 114 into the first threaded hole 113 to limit the rotating shaft 104 and prevent it from rotating further. Finally, the frame 103 can move between the two limit members 107. While moving, the limit member 107 is subjected to force to drive the connecting rod 106 to slide up and down in the connecting block 105. At this time, the compression spring 111 is subjected to force to change its own state. After the movement is completed, the limit member 107 can use the expansion force of the compression spring 111 to make its own surface fully contact with the outer surface of the frame 103, and through the cooperation of the anti-slip pad 109, it can achieve preliminary restriction of the frame 103. Figure 1 and Figure 4 As shown, the frame 103 is also provided with screw holes, so through the cooperation of the second bolt 108 and the block 110, the frame 103 can be restricted for the second time to complete the interlocking, ensuring that the frame 103 can be stably located between the two limit members 107, and the wing 102 is arranged on the frame 103. When the frame 103 is stably restricted, the wing 102 will not be subjected to force and shake, thereby avoiding damage due to shaking.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
