Description

Technical Field

[0001] The utility model relates to the field of unmanned aerial vehicles, in particular to a foldable unmanned aerial vehicle. Background Art

[0002] Foldable drones, as the name implies, are a type of drone that can be folded or stored to reduce its size, making it easier to carry and store. Foldable drones have the characteristics and functions of traditional drones, while also having greater flexibility and portability, and have a wide range of applications and uses.

[0003] In the prior art, a Chinese utility model patent with publication number "CN216003047U" and patent name "A Foldable UAV" discloses a UAV with foldable arms. The patent records the following technical solutions: "In order to meet different rotation angles and limit them, the utility model adopts a variety of clamps and corner pieces for practical use, so that the support rods in different positions can be folded at different angles and limited, and the fixing effect and stability of the locking piece during use are good";

[0004] However, in actual use, although the arms of the foldable drone can be folded, the landing gear is fixed on the belly of the drone and cannot be folded. As a result, when the drone is subsequently stored and carried, the landing gear cannot be folded, so the foldable drone still has a certain carrying height, and the landing gear is prone to breakage after being compressed during carrying, which not only brings inconvenience to the portable operation of the foldable drone, but also affects the subsequent normal use.

[0005] Therefore, in order to solve the above technical problems, the utility model proposes a foldable drone. Utility Model Content

In the process of change, the connecting rod will further tilt the bracket through the concave block on the bracket and flip it inward until the bracket is changed from a vertical state to a horizontal state, so that the bracket can be quickly folded and stored in the belly of the folding drone, and then when carrying it, not only the overall height of the folding drone is reduced to make it more convenient to carry the folding drone, but also the bracket can be prevented from being broken due to pressure when carrying, so as to ensure the normal use of the folding drone in the future.
