[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figures 1-6In this embodiment of the utility model, a folding structure for the wings of a surveying drone includes a fixed arm 1. A rotating groove 4 is provided on the outer side of one end of the fixed arm 1. A rotating seat 3 is rotatably installed on the inner wall of the rotating groove 4. A rotating arm 2 is integrally formed on one end of the rotating seat 3. A docking mechanism is distributed at the docking end of the rotating arm 2 and the fixed arm 1 and inside the fixed arm 1. A tension mechanism is provided at the end of the fixed arm 1 away from the rotating seat 3. The tension mechanism is connected to a locking mechanism through a connecting rod 14. A guide groove 15 is provided inside the fixed arm 1 for the connecting rod 14 to slide.

[0015] In this embodiment: when the rotating arm 2 is rotated and folded, an outward pulling force is applied to the pulling mechanism. At this time, the pulling mechanism drives the locking mechanism to move synchronously. At this time, the locking mechanism releases the restriction on the rotating arm 2, so the rotating arm 2 can be rotated and folded. It should be noted that: a friction rubber pad is provided at the contact position between the rotating seat 3 and the rotating groove 4. Therefore, the rotating arm 2 after rotation and folding is in a relatively stable state and will not shake randomly. When the folded rotating arm 2 is opened, a pulling force is applied to the rotating arm 2, causing the docking mechanism part on the rotating arm 2 to dock with the other part of the docking mechanism on the fixed arm 1. At this time, by pulling the pulling mechanism, the pulling mechanism drives the pulling mechanism to activate, avoiding the problem of incomplete docking of the two parts of the docking mechanism. After the two parts of the docking mechanism are fully docked, the force applied to the pulling mechanism is removed. At this time, the locking mechanism resets and limits the rotating arm 2 to prevent it from rotating.

[0016] Please refer to the figure carefully. The docking mechanism includes a docking groove 6 integrally formed on the docking end of the rotating arm 2 and a docking block 5 opened inside the fixed arm 1. The center of the docking groove 6 and the center of the docking block 5 coincide with the rotation center of the rotating seat 3. A locking groove 7 is opened on the outer periphery of the docking groove 6.

[0017] In this embodiment: during the rotation of the rotating arm 2, the rotating arm 2 drives the docking block 5 on its docking end to dock with or separate from the docking groove 6. Since the docking block 5 rotates in the docking groove 6, and since the center of the docking block 5 and the docking groove 6 coincides with the rotation center of the rotating arm 2, the rotating docking block 5 can dock with or separate from the docking groove 6.

[0018] Please refer to this carefully. Figure 4 , Figure 5 and Figure 6 The engaging mechanism includes a sliding groove 8 inside the fixed arm 1. The sliding groove 8 is located at the outer end of the docking block 5. The sliding groove 8 is connected to the inner cavity of the docking block 5. The inner wall of the sliding groove 8 is slidably connected to the engaging block 9. A spring 10 is fixedly connected between the engaging block 9 and the sliding groove 8. The top end of the vertical part of the connecting rod 14 is fixedly connected to the ground end of the engaging block 9.

[0019] In this embodiment: by pulling the pulling mechanism, the pulling mechanism pulls the locking block 9 along the sliding groove 8 through the connecting rod 14. At this time, the spring 10 is compressed until the locking block 9 is completely inserted into the interior of the sliding groove 8. At this time, the docking block 5 can be completely inserted into the docking groove 6, or the docking block 5 can be rotated out from the inner wall of the docking groove 6. After the docking block 5 is fully rotated into the docking groove 6, the locking groove 7 and the locking block 9 are aligned. At this time, the tension applied to the pulling mechanism is removed, and the spring 10 pushes the locking block 9 into the locking groove 7, thus completing the purpose of opening the rotating arm 2.

[0020] Please refer to this carefully. Figure 4 and Figure 6 The tensioning mechanism includes a connecting block 11 fixedly connected to the crossbar of the connecting rod 14 at one end, a rotating handle 12 rotatably mounted on the top of the connecting block 11, and a receiving groove 13 provided on the outer side of the fixed arm 1 to accommodate the connecting block 11 and the rotating handle 12.

[0021] In this embodiment: before pulling the pulling mechanism, the rotating handle 12 is rotated downward from the vertical position and rotated out of the receiving groove 13. At this time, the rotating handle 12 can be pulled. The rotating handle 12 drives the connecting rod 14 through the connecting block 11 to move the locking mechanism.

[0022] Please refer to this carefully. Figure 6 The contact point between the receiving groove 13 and the inner wall of the rotating handle 12 is a magnetic structure, and the rotating handle 12 is made of ferrous metal.

[0023] In this embodiment: after the tension mechanism is reset, the handle 12 is rotated upwards to a vertical position and located in the receiving groove 13. At this time, the magnet structure on the inner wall of the receiving groove 13 magnetically attracts the handle 12, preventing the handle 12 from rotating downwards.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
