Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV flight collision avoidance device. Background Technology

[0002] Unmanned aerial vehicles (UAVs), also known as drones, are unmanned aircraft controlled by radio remote control equipment and onboard program control devices. They have no cockpit but are equipped with autopilots, program control devices, and other equipment. Ground personnel, personnel on ships, or at mothership remote control stations track, locate, control, telemetry, and transmit data to them using radar and other equipment. They can be used repeatedly and are widely used for aerial reconnaissance, surveillance, communication, anti-submarine warfare, and electronic jamming. To improve the safety of UAVs, collision avoidance devices need to be installed.

[0003] Existing technologies, such as CN213566519U, describe a collision avoidance device for unmanned aerial vehicles (UAVs). This device uses an airbag on the outer wall of the fuselage to cushion the impact and protect the fuselage from damage. This solves the problem of existing UAVs lacking protective devices. Furthermore, a sealed box and air pump are installed inside the fuselage. During an impact, the sealed box inflates the airbag, thus protecting the fuselage. An adjustment mechanism is also included inside the fuselage to facilitate the opening and closing of the airbag's gas channel, allowing for easy inflation of the airbag.

[0004] However, the device still has some shortcomings in use. The drone is protected by airbags, but the airbags cannot protect the blades. In addition, the airbags need to be inflated. In the event of a collision, the situation can change in an instant, so the protection is still limited. After the drone lands, the support does not have a shock absorption effect, which reduces safety. Utility Model Content

[0005] The purpose of this utility model is to provide a drone flight anti-collision device to solve the problems mentioned in the background art, which is that the drone is protected by airbags, but the airbags cannot protect the blades. In addition, the airbags need to be inflated. Collisions are unpredictable, so there are still certain limitations in protection. After the drone lands, the support does not have a shock absorption effect, which reduces safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

The first fixing bolt is threadedly connected to the first protective plate. A second fixing bolt is provided on the bottom of the second protective plate, which passes through the second protective plate and extends into the drone body. The second fixing bolt is threadedly connected to the second protective plate.

[0009] The shock-absorbing component includes a support base at the bottom of the second protective plate. A guide groove is provided on the top of the support base. A guide rod is provided in the guide groove. A shock-absorbing spring is sleeved on the outer surface of the guide rod. A movable block is slidably connected to the outer surface of the guide rod. The movable block abuts against the shock-absorbing spring.
