Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, and in particular to an unmanned aerial vehicle rotor edge protection device and the unmanned aerial vehicle. Background Art

[0002] UAVs are unmanned aerial vehicles controlled by radio remote control equipment and self-contained program control devices. They are widely used in mineral resource exploration, emergency rescue, environmental protection, aerial photography, marine environment monitoring, land use surveys, forest fire and pest prevention and monitoring, etc. UAVs can carry a variety of payloads to complete various complex tasks, such as aerial observation and filming, package and cargo delivery, etc. During the actual flight of UAVs, birds, tall buildings, trees, high-voltage cables, etc. in the air can easily be entangled in the rotor or collide with the rotor, causing damage to the high-speed rotating rotor. The rotor edge protection device can effectively protect the rotor edge of the UAV.

[0003] However, most of the current UAV rotor edge protection devices have the following problems:

[0004] For example, a UAV flight protection device with application number CN202123175328.1 can protect the wings of the UAV through the installed protective plate, but when the protective plate is hit or collided, the protective plate is prone to deformation and loss. The deformed protective plate will also damage the wings of the UAV, and it is inconvenient to disassemble and install the damaged protective plate; at the same time, when the UAV descends, if the landing is too fast, it is easy for the UAV bracket to hit the ground. The impact force generated by the impact is easy to affect the landing stability of the UAV, causing the UAV to tilt and damage the wings, which is inconvenient to buffer and shock the impact force generated by the landing of the UAV.

[0005] Therefore, we made improvements to this and proposed a UAV rotor edge protection device. Summary of the invention

[0012] The bidirectional threaded rod is sleeved with a first moving block and a second moving block, the top of the first moving block is provided with a first clamping plate, the top of the second moving block is provided with a second clamping plate, and the first moving block and the second moving block can move towards or away from each other.

[0013] The utility model also has the following technical features:

[0014] A first anti-skid pad is arranged on the side of the first clamping plate, and a second anti-skid pad is arranged on the side of the second clamping plate. The first anti-skid pad and the second anti-skid pad are arranged opposite to each other.

[0015] The arc-shaped protective plate is also provided with ventilation slots at equal distances.

[0016] The utility model also provides a drone, comprising a drone body and drone wings installed on both sides of the drone body, wherein the drone wings are installed with the above-mentioned drone rotor edge protection device.

[0017] The arc-shaped protective plate is located on the outer side of the propeller of the UAV wing.

[0021] The support box further comprises a through hole formed on the top surface of the support box body, the through hole being connected to the sliding damping installation groove;

[0022] The buffer shock absorber comprises a longitudinal damper and a sliding damper;
