Description

Technical Field

Multirotor UAVs have high requirements for take-off and landing sites, requiring the site to be relatively flat to ensure take-off and landing safety; searching for a suitable take-off and landing point will delay the rescue time.

[0003] Currently, in the prior art, generally, a take-off and landing platform is carried to conveniently and quickly obtain a flat site. For example, in the existing patent document "CN219447355U A Multirotor UAV Take-off and Landing Platform", it includes a platform body, a telescopic bracket, and a circular bubble level. Four connecting seats are fixedly installed on the lower surface of the platform body. The lower part of each connecting seat is rotatably connected to the telescopic bracket through a threaded rod. The lower end of the telescopic bracket is a pointed structure. By setting the connecting seats and the telescopic bracket, it is not only convenient to fold and easy to carry, but also can adjust the lifting and using height according to actual needs. With the use of the threaded rod and the tension nut, the opening and closing angle of the telescopic bracket can be adjusted, which facilitates the UAV operation of multirotor UAVs in areas such as rough ground, muddy, and weedy areas, and is convenient for fixing the UAV landing platform. By setting the circular bubble level, the angles and lengths of the four telescopic brackets can be adjusted in cooperation to make the platform body horizontal, with a simple structure and convenient operation.
