In actual use, if the operator operates the UAV to land too fast, the impact force of the fast landing will be transmitted to the UAV body through the landing bracket. The circuit connectors, sensors, flight control and camera structures in the UAV body are easily damaged under the impact force, which affects the usability of the UAV.

The lower sleeve and the buffer spring part are designed with three groups, which are distributed in a ring at the bottom of the lower buffer part. The triangular layout structure can absorb the impact of landing in multiple directions. The subsequent force generated during the absorption will be transmitted from the three groups of contact feet and the lower sleeve to the lower buffer part, and then transmitted to the bottom of the drone body through the upper frame. Through the design of this mechanism, the impact force generated by landing can be effectively absorbed, reducing the negative impact of the impact force on the equipment in the main body of the drone, and improving the usability of the drone;

The sleeve member is in sliding contact with the guide rod member through the groove, and the guide rod member is used to guide the position of the sleeve member.

[0029] Working principle: The UAV landing bracket in the prior art lacks a buffer mechanism. In actual use, if the operator operates the UAV to land too fast, the impact force of the rapid landing will be transmitted to the UAV body 01 through the landing bracket. The line connectors, sensors, flight control and camera structures in the UAV body 01 are easily damaged under the impact force, affecting the usability of the UAV. In the corresponding designed buffer bracket component group 02, when landing, multiple groups of contact feet 25 will first contact the ground. The recoil force received after contact will be transmitted to the buffer spring member 26, and the buffer spring member 26 will absorb the impact force of landing. The impact force absorbed by the buffer spring member 26 is transmitted to the drone body 01. The lower sleeve 24 and the buffer spring member 26 are designed to be three groups, which are distributed in a ring shape at the bottom of the lower buffer member 23. The triangular layout structure can absorb the impact of landing in multiple directions. The subsequent force generated during the absorption will be transmitted from the three groups of contact feet 25 and the lower sleeve 24 to the lower buffer member 23, and then will be transmitted to the bottom of the drone body 01 through the upper frame 21. Through the design of this mechanism, the impact force generated by the landing can be effectively absorbed, reducing the negative impact of the impact force on the equipment in the drone body 01, and improving the usability of the drone. The current drone landing bracket lacks an adjustable mechanism. In actual use, the height of the landing bracket cannot be adjusted according to the height position of items mounted on the bottom of the drone, such as cameras and other equipment, which reduces the applicability of the landing bracket. In the corresponding designed adjustment component group 03, by rotating the adjustment knob 33, the threaded rod 31 will be driven to rotate, and the rotation of the threaded rod 31 through the thread will drive the sleeve member 22 to move up and down. The sleeve member 22 is in sliding contact with the guide rod 35 through the groove. The guide rod 35 is used to guide the position of the sleeve member 22. Adjusting the position of the sleeve member 22 allows the buffer bracket component group 02 structure to adjust the support height of the buffer bracket component group 02 according to the items mounted on the bottom of the drone body 01, so that the buffer bracket component group 02 can contact the ground and avoid the equipment mounted on the bottom from contacting the ground. The adjustable structure is simple to set up and can be adjusted quickly and effectively, thereby improving the adjustability and applicability of the overall drone bottom bracket.
