[0002] A UAV is an unpiloted aircraft that is controlled by a radio remote control device and a self - contained program control device, or is operated completely or intermittently autonomously by an on - vehicle computer. The UAV landing gear can, to a certain extent, reduce the vibration level of the UAV during landing or ground taxiing, and play a certain protective role for the hard components at the bottom of the UAV fuselage.

[0003] Chinese Patent with application number CN202323170139.4 discloses a landing gear of a UAV, which includes a device frame, universal wheels and a support base. Hinged seats are installed at four ends of the device frame, and connecting rods are fixedly connected inside the hinged seats. By setting the hinged seats under the device frame to install the connecting rods, when the device needs to be moved, the universal wheels at the lower end of the connecting rods will drive the device to move, and the shock absorbers at the upper end of the universal wheels can buffer the vibration to make the movement more stable. Then, when the device frame needs to be fixed or when the UAV needs to take off and land, the support base on its side can be moved to the bottom by rotating the grip, then the universal wheels are lifted off the ground, and then a fixing rod is inserted into the hole where the hinged seat and the support base overlap to fix it. After that, when the support base contacts the ground, it will effectively improve the friction and stability between the device and the ground, making the landing and receiving of the UAV more stable.

[0004] However, the above - mentioned prior art is not convenient for the landing gear to be used on uneven ground, has poor stability, and at the same time cannot protect the top of the UAV.

[0005] In view of this, the present utility model is specifically proposed. Summary of the Utility Model

Detailed description of the specific implementation

[0026] Now, the present utility model will be further described in detail with reference to the drawings.

[0027] Please refer to Figures 1-4 As shown, in this embodiment, an unmanned aerial vehicle landing gear is provided, including a fixed plate 1 and a mounting frame 2. The top of the mounting frame 2 is fixed to the bottom of the fixed plate 1. An adjustable support assembly 3 is rotatably installed inside the mounting frame 2. A buffer rod 4 is fixedly installed on the top of the fixed plate 1. The buffer rod 4 has a certain buffering effect on the lifting plate 5. The top of the buffer rod 4 is fixedly installed with a lifting plate 5. A groove is provided on the top of the lifting plate 5. A rotary clamping assembly 6 is fixedly installed inside the groove. A buffer foam board 7 is provided on the top of the lifting plate 5. A drawer 8 is fixed to the bottom of the lifting plate 5. The drawer 8 can centrally place maintenance tools, facilitating the timely maintenance of the unmanned aerial vehicle.

[0028] One application of this embodiment is as follows: The user can drive the landing gear to move by using the adjustable support assembly 3, which facilitates the adjustment of the position of the landing gear. Then, the user rotates the adjustable support assembly 3 to increase the contact area between the landing gear and the ground, making the landing gear more stable. The UAV starts and stops on the top of the buffer foam board 7. Then, the rotary clamping assembly 6 can clamp and fix both sides of the UAV. The buffer foam board 7 and the rotary clamping assembly 6 buffer the bottom and both sides of the UAV respectively, preventing the internal components of the UAV from loosening. The rotary clamping assembly 6 can also protect the top of the UAV.

[0029] The adjustable support assembly 3 includes a rotating shaft 301 and a turntable 302. One end of the rotating shaft 301 is rotatably installed on one side inside the mounting frame 2, and the turntable 302 is fixed to the other end of the rotating shaft 301. The turntable 302 is located on the other side outside the mounting frame 2 for convenient rotation adjustment. An adjustment cylinder 303 is fixed to the outer side of the rotating shaft 301. An adjustment rod 304 is installed in the adjustment cylinder 303 in a threaded manner. The other end of the adjustment rod 304 is fixed to a base 305. A shock absorber 306 is fixedly installed on the outer side of the rotating shaft 301. The shock absorber 306 and the adjustment cylinder 303 are arranged at a right angle, making it more convenient to replace the moving wheel 307 and the base 305. A moving wheel 307 is fixedly installed at the bottom of the shock absorber 306.

[0030] When this embodiment is in use, the user can drive the landing gear and the UAV to move by using the moving wheel 307, and the shock absorber 306 can damp the moving frame. After the movement is completed, rotating the turntable 302 can drive the rotating shaft 301 to rotate, thereby driving the adjustment cylinder 303, the adjustment rod 304, and the base 305 to rotate. The base 305 is in contact with the ground, increasing the contact area and improving the stability of the landing gear. Moreover, there are thread protrusions inside the adjustment cylinder 303 and thread grooves on the outer side of the adjustment rod 304, enabling the height of the base 305 to be adjusted according to the ground flatness.

[0031] The rotary clamping assembly 6 includes a servo motor 601 and a bidirectional screw 602. The servo motor 601 is fixedly installed on one side inside the groove, and the bidirectional screw 602 is installed at the output end of the servo motor 601. The other end of the bidirectional screw 602 is rotatably installed on the other side inside the groove. Sliders 603 are installed on the outer side of the bidirectional screw 602. The sliders 603 are threadedly connected to the bidirectional screw 602. The sliders 603 are located inside the groove. A fixing frame 604 is fixed to the top of the sliders 603. A mounting shaft 605 is rotatably installed at the top of the fixing frame 604, which can drive the protection plate 606 to rotate. A protection plate 606 is fixed to the outer side of the mounting shaft 605. A rubber column 607 is fixed to one side of the fixing frame 604.

[0032] In use, when the servo motor 601 operates, it can drive the bidirectional screw 602 to rotate. Both sides of the slider 603 are in contact with the inner side walls of the groove. The groove has a limiting effect on the slider 603, enabling the slider 603 to slide on the bidirectional screw 602 instead of rotating. Finally, the position of the fixing frame 604 can be adjusted to facilitate the clamping and fixing of the drone. The rubber column 607 has a buffering effect on the drone. Finally, the user rotates the mounting shaft 605 and the protective plate 606 to protect the top of the drone.

[0033] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, fall within the protection scope of the present utility model. The technologies, shapes, and structures not described in detail in the present utility model are all well-known technologies.
