During the flight of the drone, the landing gear can be completely stored at the bottom, the wind-receiving area is reduced during flight, the kinetic energy required is reduced, and the endurance is increased. The horizontally arranged long support plate increases the fulcrum to avoid tilting and falling when inserted into the soft ground, thereby improving the safety of the drone.

[0005] However, the above device can only be used on flat ground during takeoff. In other complex environments such as sandy ground or muddy ground with slopes, it is impossible to ensure that the drone is in a horizontal state during takeoff, resulting in failure of the drone to take off.

A handle is fixedly connected below the recovery bolt, and an auxiliary disk is rotatably connected to the surface of the handle. A plurality of connecting grooves are opened on the surface of the auxiliary disk, and a plurality of auxiliary blocks are rotatably connected in the plurality of connecting grooves.

[0010] Preferably, the self-locking assembly includes multiple springs, one ends of the multiple springs are fixedly connected to the slide grooves opened on the inner walls of the multiple bases, and the other ends are fixedly connected to multiple protrusions, one ends of the multiple protrusions are slidably connected to the slide grooves opened on the inner walls of the multiple bases, and the other end surfaces are hemispherical, and the hemispherical shapes are slidably engaged in the fixed grooves opened at the bottoms of the multiple support rods.

[0011] Preferably, a plurality of fixed cones are arrayed under each of the plurality of bases.

[0012] Preferably, an anti-slip groove is provided on the surface of the handle.

[0013] Preferably, anti-slip grooves are provided on the surfaces of the adjusting bolts.

[0014] The working principle and use principle of the utility model are as follows: the drone body is placed in a complex environment such as sand or a muddy ground surface with a slope, and then a plurality of adjusting bolts are rotated to make the adjusting bolts disengage from the inner wall of the connecting rod, and the distance between the connecting rod and the adjusting bolt is increased, so that the connecting rod drives the support rod to move outward, and at the same time, one end of the support rod is flipped on the inner wall of the connecting block, and the angle of the support rod is adjusted so that the angle of the support rod can adapt to the muddy ground surface with a slope. At the same time, the support rod drives the base to move, and a plurality of bases contact the ground, and a plurality of fixed cones on the surfaces of the plurality of bases penetrate into the ground to prevent the device from slipping. When the bracket mechanism needs to be recovered, the handle is rotated to make the handle drive the recovery bolt to rotate, so that the recovery bolt is recovered into the threaded hole opened under the connecting block, so that the handle drives the auxiliary plate to move, and at the same time the auxiliary plate drives the auxiliary block upward, so that the auxiliary block drives the adjusting bolt and the connecting rod to flip, and then drives the support rod to flip, so that the support rod contacts the surface below the drone body, saving space and facilitating the storage of the drone body.

[0015] The beneficial technical effect of the utility model is that the support mechanism can be conveniently folded to save space through the folding mechanism, and the angle of the support rod can be changed by increasing the distance between the connecting rod and the adjusting bolt when the adjusting bolt is separated from the inner wall of the connecting rod, so that the support mechanism can adapt to complex environments such as sandy land or muddy land with slopes, etc., to ensure that the drone body is in a horizontal state when taking off.

[0022] The specific implementation of the utility model will be further described in detail below with reference to the accompanying drawings.

[0023] A drone landing gear under this specific implementation method, such as Figure 1-5As shown, a drone landing gear includes a drone body 1, a connecting block 2 is fixedly connected to the bottom of the drone body 1, a folding mechanism is movably installed under the connecting block 2, the folding mechanism is convenient for folding the bracket mechanism to save space, the surface of the connecting block 2 is rotatably connected to the bracket mechanism, the bracket mechanism supports the drone body 1, the bracket mechanism includes a plurality of support rods 6, one end of the plurality of support rods 6 is rotatably connected to the bottom of the connecting block 2, and the other end is rotatably connected to a plurality of bases 10, and a plurality of fixed cones are arrayed under the plurality of bases 10, which can be used on a sandy surface. The high grip of the base 10 makes the base 10 more stable to the drone body 1. The inner walls of the multiple bases 10 are movably connected with multiple self-locking components, which facilitate real-time adjustment of the angle of the base 10. One side of the middle of the multiple support rods 6 is rotatably connected with multiple connecting rods 7. The inner walls of the multiple connecting rods 7 are threadedly connected with one end of multiple adjusting bolts 8. When the adjusting bolts 8 are rotated, the adjusting bolts 8 are separated from the inner walls of the connecting rods 7. The other ends of the multiple adjusting bolts 8 are rotatably connected with multiple auxiliary blocks 9. The surfaces of the adjusting bolts 8 are provided with anti-slip grooves to facilitate the rotation of the adjusting bolts 8.

[0024] Through the above technical solution, the drone body 1 is placed in a complex environment such as sand or a muddy surface with a slope. The staff places a spirit level on the drone body 1, and then rotates multiple adjusting bolts 8 to disengage the adjusting bolts 8 from the inner wall of the connecting rod 7. The distance between the connecting rod 7 and the adjusting bolt 8 increases, so that the connecting rod 7 drives the support rod 6 to move outward, and at the same time, one end of the support rod 6 is flipped on the inner wall of the connecting block 2, and the angle of the support rod 6 is adjusted. By observing the spirit level, it is ensured that the drone body 1 is in a horizontal state when taking off, so that the angle of the support rod 6 can adapt to the muddy surface with a slope. At the same time, the support rod 6 drives the base 10 to move, and multiple bases 10 contact the ground. Multiple fixed cones on the surface of multiple bases 10 penetrate into the ground to prevent the device from slipping.

[0025] The drone body 1 is a prior art, and has the same internal structure as the drone for sand prevention and control disclosed in Chinese Patent Publication No. CN218703898U, and will not be described in detail here.

[0026] like Figure 1-5 As shown, the folding mechanism includes a recovery bolt 3, which is threadedly connected to a threaded hole opened below the connecting block 2, and a handle 4 is fixedly connected below the recovery bolt 3. An anti-slip groove is opened on the surface of the handle 4, and an auxiliary plate 5 is rotatably connected to the surface of the handle 4. A plurality of connecting grooves are opened on the surface of the auxiliary plate 5, and a plurality of auxiliary blocks 9 are rotatably connected in the plurality of connecting grooves.

[0027] Through the above technical solution, when the bracket mechanism needs to be recovered, the handle 4 is rotated to make the handle 4 drive the recovery bolt 3 to rotate, so that the recovery bolt 3 is recovered into the threaded hole opened under the connecting block 2, and the handle 4 drives the auxiliary plate 5 to move. At the same time, the auxiliary plate 5 drives the auxiliary block 9 upward, so that the auxiliary block 9 drives the adjusting bolt 8 and the connecting rod 7 to flip, and then drives the support rod 6 to flip, so that the support rod 6 contacts the lower surface of the drone body 1, saving space and facilitating the storage of the drone body 1.

[0028] like Figure 1-5 As shown, the self-locking assembly includes multiple springs 11, one end of each of the multiple springs 11 is fixedly connected to a slide groove opened on the inner wall of a plurality of bases 10, and the other end is fixedly connected to a plurality of protrusions 12, one end of each of the multiple protrusions 12 is slidably connected to the slide groove opened on the inner wall of the plurality of bases 10, and the other end surface is hemispherical, and the hemispherical shapes are slidably engaged in the fixed groove opened at the bottom of the plurality of support rods 6.

[0029] Through the above technical solution, the protrusion 12 in the base 10 is driven by the spring 11, and the hemispherical end of the protrusion 12 will be engaged in the fixed groove opened at the bottom of the support rod 6. When the base 10 is flipped, the support rod 6 squeezes the protrusion 12, so that the protrusion 12 compresses the spring 11 and returns to the slide groove of the base 10. Then, when passing through the fixed groove opened at the bottom of the next support rod 6, the spring 11 drives the protrusion 12, so that the hemispherical end of the protrusion 12 is engaged in another fixed groove at the bottom of the support rod 6, thereby completing the real-time adjustment of the angle of the base 10.
