[0026] The present invention is described in detail below in conjunction with the accompanying drawings so that ordinary technicians in the field can implement it according to the instructions.

[0027] like Figure 1-4 As shown, the landing stable drone comprises: a drone body 1,

[0028] A mounting plate 2 is arranged below the drone body 1, and the mounting plate 2 is fixedly connected to the drone body 1 by screws. Two mounting plates 2 are provided, and the two mounting plates 2 are symmetrically arranged. The front end and the rear end below the mounting plate 2 are symmetrically fixedly installed with connecting plates 3, and a landing rod 5 is installed below the connecting plate 3;

[0029] The stabilizing block 6 is arranged below the descending rod 5, and a block cavity 601 is arranged inside the stabilizing block 6. A buffer rubber block 7 is arranged above the block cavity 601, and the buffer rubber block 7 is fixedly connected to the stabilizing block 6 by screws. A buffer column 8 is bonded and installed below the buffer rubber block 7, and the lower end of the buffer column 8 passes through the interior of the stabilizing block 6. A bottom plate 9 is fixedly installed below the buffer column 8, and a rubber pad is bonded and installed below the bottom plate 9.

[0030] In the above scheme, the landing rod is set to be tilted as a whole. When the drone lands and contacts the ground, the force generated by the landing is transmitted to the buffer column through the bottom plate. The buffer rubber block absorbs and disperses the force, which can reduce the force generated by the drone landing and increase the stability of the drone landing.

[0031] In a preferred embodiment, the drop rod 5 includes a straight tube 501, a straight rod 502 and a bottom column 503. The straight tube 501 is rotatably connected to the connecting plate 3. The bottom column 503 is fixedly connected to the stabilizing block 6 by screws. The bottom column 503 is fixedly installed below the straight rod 502. The straight rod 502 is inserted into the interior of the straight tube 501. A fixing bolt 10 is threadedly installed on one side of the straight tube 501. The screw end of the fixing bolt 10 penetrates into the interior of the straight tube 501 and contacts with the straight rod 502. Scale lines are provided on the outer surface of the straight rod 502.

[0032] In the above scheme, the length of the landing rod can be adjusted by adjusting the extension and retraction of the straight rod in the straight tube, which increases the flexibility of using the landing rod, and the position of the straight rod can be fixed by the set fixing bolts, so that the overall length of the landing rod can be stably maintained after adjustment, and the telescopic size of the straight rod can be checked through the scale lines on the surface of the straight rod, so that the four landing rods of the drone can be adjusted to the same length.

[0033] In a preferred embodiment, a connecting arm 4 is installed on one side below the mounting plate 2. The connecting arm 4 includes an upper connecting piece 401, an upper arm tube 402, a buffer rubber ring 403, a lower arm tube 404 and a lower connecting piece 405. The upper connecting piece 401 is rotatably connected to the mounting plate 2, and the lower connecting piece 405 is rotatably connected to the straight tube 501.

[0034] In the above scheme, the upper connecting piece and the lower connecting piece are rotatably connected to the mounting plate and the straight tube respectively, so that the connecting arm is rotatably installed between the mounting plate and the straight tube, which is beneficial to the buffering work of the connecting arm.

[0035] In a preferred embodiment, the upper arm tube 402 is fixedly installed below the upper connecting piece 401 , the buffer rubber ring 403 is fixedly installed below the upper arm tube 402 , the lower arm tube 404 is fixedly installed below the buffer rubber ring 403 , and the lower connecting piece 405 is fixedly installed below the lower arm tube 404 .

[0036] In the above scheme, the buffer rubber ring is respectively bonded to the upper arm tube and the lower arm tube by glue. The setting of the buffer rubber ring can not only provide buffering capacity, but also seal between the upper arm tube and the lower arm tube to prevent dust from entering the connecting arm.

[0037] In a preferred embodiment, a compression spring 11 is fixedly installed on the upper part of the upper arm tube 402, a guide column 12 is fixedly installed below the compression spring 11, the lower end of the guide column 12 extends into the interior of the lower arm tube 404, a connecting rod 13 is fixedly installed below the guide column 12, a bottom block 14 is fixedly installed below the connecting rod 13, and the bottom block 14 is fixedly connected to the lower arm tube 404 by screws.

[0038] In the above scheme, when the drone lands too fast and generates too much impact force, the landing rod is installed in an inclined and rotating manner, so that the landing rod is subjected to the impact force of the fall, and the bottom of the landing rod can slide outward, at which time the connecting arm will be pressed. The impact force can be buffered by the action of the buffer rubber ring and the compression spring in the connecting arm, thereby improving the stability and safety of the drone's landing.

[0039] In a preferred embodiment, a stabilizing rubber ring 15 is provided on the outer side of the connecting rod 13 .

[0040] In the above scheme, by setting the stable rubber ring, the rebound force of the compression spring can be buffered and absorbed, thereby increasing the landing stability of the drone.
