Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicle frames, in particular to an unmanned aerial vehicle frame. Background Art

[0002] Unmanned aircraft, referred to as "drones", are unmanned aircraft controlled by radio remote control equipment and self-contained program control devices, or are completely or intermittently autonomously operated by on-board computers. With the development of drone aircraft technology, drone aircraft have been widely used in agricultural plant protection, aerial photography, power inspection, environmental monitoring, forest fire prevention and disaster inspection due to their advantages such as flexibility, unmanned flight and low operating requirements.

[0003] For example, a drone frame disclosed in the utility model with authorization announcement number CN208264549U is formed by integrating the base and the arm of the drone frame, has high strength and light weight, so that the drone is relatively stable during flight, thereby reducing the error of shooting detection and improving the accuracy of drone use. Due to its own high flexibility, the drone has a wide range of applications. Therefore, when encountering some rugged terrain, it is not conducive to the take-off and landing of the drone, which will affect the subsequent normal use of the drone. Therefore, a drone frame is needed to facilitate the flight and landing of the drone. However, the existing drone frame is not easy to carry and is mostly assembled by bolts. Both assembly and disassembly are relatively laborious and have poor practicality. Utility Model Content

[0006] As a preferred technical solution of the utility model, the locking structure includes a placement groove, a guide groove and a locking groove. The placement groove is opened in the middle of the top end of the frame, the inner side wall of the top end of the frame is provided with a guide groove, and the top end of the frame is provided with a locking groove.

[0007] As a preferred technical solution of the utility model, a second spring is arranged on the inner side of the placement groove, and the other end of the second spring is fixedly connected to a buffer seat, a buffer pad is arranged on the upper surface of the buffer seat, a guide block is installed on the side wall of the buffer seat, and a second damper is distributed on one side of the second spring.

[0008] As a preferred technical solution of the present utility model, the extension legs are rotationally connected to the frame body via the rotating shaft, and the extension legs are symmetrically distributed along the vertical center line of the frame body.

[0009] As a preferred technical solution of the utility model, the locking rod is slidably connected to the extension leg through the auxiliary slide plate, and the locking rod and the extension leg are vertically distributed.

[0010] As a preferred technical solution of the present utility model, the second springs are equidistantly distributed at the bottom of the buffer seat, and the buffer seats are distributed in parallel.

[0011] Compared with the prior art, the utility model can achieve the following beneficial effects:
