Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0026] A tripod for an unmanned aerial vehicle that is convenient for retracting and extending, comprising:

[0027] The body includes an unmanned aerial vehicle 1. The unmanned aerial vehicle 1 is an existing product and is not the technical protection point of this application, so no further description will be made here.

[0028] The storage mechanism includes a connecting block 2. The connecting block 2 is fixedly connected to the surface of the unmanned aerial vehicle 1 and is used to connect a rotating ball 21. The surface of the connecting block 2 is rotatably connected to the rotating ball 21, which is used to drive the first support leg 26 to rotate. The surface of the rotating ball 21 is fixedly connected with a limiting plate 22, which is used to limit the position of the rotating ball 21 to prevent the rotating ball 21 from falling off the surface of the connecting block 2. The surface of the rotating ball 21 is sleeved with a fixing threaded rod 23 through threads, which is used to fix the position of the rotating ball 21. The surface of the fixing threaded rod 23 is fixedly connected with a movable plate 24, which is used to limit the positions of the fixing threaded rod 23 and the rotating handle 25. The side of the movable plate 24 away from the fixing threaded rod 23 is fixedly connected with a rotating handle 25, which is used to drive the fixing threaded rod 23 to rotate. The surface of the rotating ball 21 is fixedly connected with a first support leg 26, which is used to be received into the second support leg 27 to reduce the storage volume. The surface of the first support leg 26 is sleeved with a second support leg 27 through threads, which is used to receive the first support leg 26. The surface of the second support leg 27 is fixedly connected with a connecting threaded rod 28, which is used to connect a connecting groove 29. The surface of the connecting threaded rod 28 is sleeved with the connecting groove 29 through threads, which is used to fix the support foot 3 on the surface of the second support leg 27.

[0029] The buffer mechanism includes a support foot 3. The support foot 3 is arranged on the surface of the unmanned aerial vehicle 1 and is used to support the whole. The surface of the support foot 3 is sleeved with a connecting ring 31, which is used to connect a guiding groove 32 and at the same time keep the guiding groove 32 always vertical. The surface of the connecting ring 31 is fixedly connected with the guiding groove 32, which is used to guide a buffer spring 33 and a support ball 34. The surface of the guiding groove 32 is fixedly connected with the buffer spring 33, which is used to buffer the support ball 34. The surface of the buffer spring 33 is fixedly connected with the support ball 34, which is used to support when touching the ground. The surface of the support foot 3 is fixedly connected with a limiting ring 35, which is used to connect a limiting rod 36. The surface of the limiting ring 35 is fixedly connected with the limiting rod 36, which is used to limit the rotation angle of the guiding groove 32.

[0030] Furthermore, two groups of connecting blocks 2 are distributed on the surface of the unmanned aerial vehicle 1. The two groups of connecting blocks 2 are staggeredly distributed on both sides of the unmanned aerial vehicle 1 to better receive the second support leg 27 and the support foot 3. An activity groove is opened inside the connecting block 2 for the movable plate 24 to move. The limiting plate 22 penetrates through the surface of the connecting block 2 and is fixedly connected to the surface of the rotating ball 21, so as to ensure that while the rotating ball 21 rotates, the position of the rotating ball 21 is limited to prevent the rotating ball 21 from falling off the surface of the connecting block 2.

[0031] Further, the rotating ball 21 is rotatably connected to the surfaces of the limiting plate 22 and the connecting block 2. Rotating the rotating ball 21 can drive the limiting plate 22 to rotate on the surface of the connecting block 2. The rotating handle 25 is movably connected to the surfaces of the connecting block 2 and the rotating ball 21. Rotating the rotating handle 25 drives the movable plate 24 and the fixed threaded rod 23 to rotate, so that the fixed threaded rod 23 is connected to the rotating ball 21, thereby fixing the position of the rotating ball 21.

[0032] Further, the movable plate 24 is movably connected inside the connecting block 2. The movable plate 24 moves in the movable groove inside the connecting block 2. The fixed threaded rod 23 is threadedly sleeved on the surface of the connecting block 2, thereby fixing the position of the rotating ball 21. The fixed threaded rod 23 is movably connected to the surfaces of the movable plate 24 and the connecting block 2. The rotating ball 21 is fixedly connected to the surface of the connecting block 2 through the fixed threaded rod 23. Rotating the rotating handle 25 drives the movable plate 24 to rotate and move, thereby driving the fixed threaded rod 23 to rotate and move, and then tightening it on the surface of the rotating ball 21 to fix the position of the rotating ball 21.

[0033] Further, the rotating ball 21 is movably connected to the surfaces of the first support leg 26 and the second support leg 27. Rotating the rotating ball 21 drives the first support leg 26 to rotate on the surface of the unmanned aerial vehicle 1. The second support leg 27 is fixedly connected to the surfaces of the connecting threaded rod 28 and the connecting groove 29. The connecting groove 29 can be tightened at the connecting threaded rod 28, thereby connecting the second support leg 27 to the support foot 3, and at the same time enabling the support foot 3 to rotate on the surface of the second support leg 27. The connecting groove 29 is fixedly connected to the surface of the support foot 3. Rotating the rotating ball 21 drives the support foot 3 to rotate. The support foot 3 is rotatably connected to the surface of the unmanned aerial vehicle 1 through the rotating ball 21. Rotating the rotating ball 21 drives the first support leg 26 to rotate, and further drives the second support leg 27 to rotate, thereby driving the support foot 3 to rotate.

[0034] Further, two sets of connecting rings 31 are symmetrically distributed on the surface of the support foot 3. The distribution of the two sets of connecting rings 31 performs buffering treatment from both ends of the support foot 3 to ensure the overall balance. The support ball 34 is movably connected to the surfaces of the buffer spring 33 and the guide groove 32. The support ball 34 contacts the ground, thereby compressing the buffer spring 33 and moving towards the support foot 3. The deformation of the buffer spring 33 forms a buffer for the support ball 34.

[0035] Furthermore, the limiting rings 35 are symmetrically distributed in two groups on the surface of the support feet 3. The two groups of limiting rings 35 limit the two groups of connecting rings 31. The limiting rods 36 are symmetrically distributed in two groups on the surface of the limiting rings 35 and are used to limit the rotation angle of the guiding grooves 32, avoiding excessive inclination after the supporting balls 34 contact the ground, which affects the buffering efficiency. The limiting rods 36 are connected by abutting against the surfaces of the limiting rings 35 and the guiding grooves 32. When the guiding grooves 32 rotate to the position of the limiting rods 36, they are abutted by the limiting rods 36, so that their positions are restricted to ensure the buffering efficiency.

[0036] Working principle: When using the unmanned aerial vehicle 1, first sleeve the connecting groove 29 on the connecting threaded rod 28 to fix the support feet 3 on the surface of the second support leg 27, and then sleeve the second support leg 27 on the surface of the first support leg 26 and tighten it. Then rotate the rotating ball 21 to expand the second support leg 27 and the support feet 3 to an appropriate support angle. After determining the expansion angle, rotate the rotating handle 25 to drive the movable plate 24 and the fixed threaded rod 23 to rotate and move, so that the fixed threaded rod 23 is tightened on the surface of the rotating ball 21 to fix the rotation angle of the rotating ball 21. Then the unmanned aerial vehicle 1 can be started for use. When the unmanned aerial vehicle 1 takes off, the connecting ring 31 drives the guiding groove 32 to rotate to make the guiding groove 32 vertical. When the unmanned aerial vehicle 1 lands after use, the supporting ball 34 contacts the ground and moves towards the guiding groove 32, thereby compressing the buffer spring 33. The buffer spring 33 deforms to buffer the supporting ball 34. The connecting ring 31 will drive the guiding groove 32 to rotate until it abuts against the surface of the limiting rod 36 to be restricted, and then the buffering is completed. After tightening the second support leg 27 so that the first support leg 26 is completely inside the second support leg 27, rotate the support feet 3 so that the support feet 3 rotate 90 degrees. Then rotate the rotating handle 25 to separate the rotating ball 21 and the fixed threaded rod 23. Then rotate the rotating ball 21 to place the support feet 3 on the upper end of the unmanned aerial vehicle 1, and then rotate the rotating handle 25 to fix the rotating ball 21, thus completing the storage.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
