As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0023] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, the embodiment of the utility model provides a landing gear for a drone, comprising four anti-tilt components 101, a vibration reduction component 201 and a shell 30;

[0025] The four anti-tilt components 101 each include a fixing seat 10, a fixing column 11, a first slide slot 12, a first slide block 13, a screw rod 14, a driving motor 15, a fixing rod 16, a plate body 17 and a fixing plate 18;

[0026] The top of the fixed base 10 is fixedly connected to the bottom of the shell 30, the bottom of the fixed base 10 is fixedly connected to the top of the fixed column 11, the inner wall of the fixed column 11 is provided with a first slide groove 12, one side of the first slider 13 is slidably connected to the inside of the first slide groove 12, the outer wall of the screw rod 14 is threadedly connected to the inside of the first slider 13, the outer wall of the drive motor 15 is fixedly connected to the inner wall of the fixed column 11, and the output end of the drive motor 15 is fixedly connected to one end of the screw rod 14.

[0027] In one embodiment, one end of the fixing rod 16 is fixedly connected to one side of the first slider 13, and the other end of the fixing rod 16 is fixedly connected to the top of the plate body 17. The bottom of the plate body 17 is hinged to the top of the fixing plate 18. The first slider 13 and the plate body 17 are arranged to fix the fixing rod 16. The plate body 17 is arranged to fix the fixing plate 18. An anti-slip groove is provided at the bottom of the fixing plate 18. When the UAV lands on an uneven ground, the screw rod 14 is driven to rotate by controlling the drive motor 15 so that the fixing rod 16 extends out from the fixing column 11. By arranging four anti-tilt components 101, each anti-tilt component 101 can be controlled separately to avoid the risk of tilting and tipping over during landing, thereby reducing the probability of damage to the UAV and improving the service life of the UAV.

[0028] In one embodiment, the shock absorbing assembly 201 includes a second slide groove 20, a second slider 21, a damper 22, a spring 23, a connecting rod 24 and a mounting plate 25; the inner bottom wall of the shell 30 is provided with a second slide groove 20, and the bottom of the second slider 21 is slidably connected to the inside of the second slide groove 20. The second slide groove 20 is fixed by the setting of the shell 30.

[0029] In one embodiment, one end of the damper 22 is fixedly connected to the inner wall of the shell 30, and the other end of the damper 22 is fixedly connected to one side of the second slider 21. The outer wall of the damper 22 is sleeved with a spring 23. The setting of the shell 30 fixes the damper 22, and the setting of the damper 22 fixes the second slider 21 and the spring 23.

[0030] In one embodiment, the top of the second slider 21 is hinged to one end of the connecting rod 24, and the other end of the connecting rod 24 is hinged to the bottom of the mounting plate 25. The second slider 21 is arranged to fix the connecting rod 24, and the mounting plate 25 is fixed by the arrangement of the connecting rod 24. During landing, the mounting plate 25 squeezes the connecting rod 24, and the connecting rod 24 drives the second slider 21 to squeeze the damper 22 and the spring 23. The damper 22 and the spring 23 generate a reverse thrust, prompting the mounting plate 25 to reset, thereby reducing the vibration of the UAV and preventing the UAV from being damaged by vibration.

[0031] In one embodiment, a panoramic camera 31 is installed at the bottom of the shell 30 , and the panoramic camera 31 is fixed by the setting of the shell 30 .

[0032] During operation of the utility model: when the UAV is landing on an uneven ground, the landing location is observed through the panoramic camera 31, and the driving motor 15 is controlled to drive the screw 14 to rotate, so that the fixing rod 16 extends from the fixing column 11, and the fixing rod 16 drives the fixing plate 18 to be close to the ground. By setting four anti-tilt components 101, each anti-tilt component 101 can be controlled separately to avoid the risk of tilting and tipping over during landing, thereby reducing the probability of damage to the UAV. During landing, the mounting plate 25 squeezes the connecting rod 24, and the connecting rod 24 drives the second slider 21 to squeeze the damper 22 and the spring 23. The damper 22 and the spring 23 generate a reverse thrust, which prompts the mounting plate 25 to reset, thereby reducing the vibration of the UAV, avoiding damage to the UAV due to vibration, and thus increasing the service life of the UAV.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
