Unmanned aerial vehicle launching frame

Abstract

An unmanned aerial vehicle launching frame is characterized in that the unmanned aerial vehicle launching frame comprises a base frame, a front supporting assembly and a rear supporting assembly; the front supporting assembly is arranged at the front end of the base frame to support the front portion of an unmanned aerial vehicle, and the rear supporting assembly is arranged at the rear end of the base frame and can support the tail portion of the unmanned aerial vehicle; the rear supporting assembly comprises a rear supporting column, a U-shaped support and a self-locking spring, the rear supporting column is fixed to the base frame, and the two ends of the U-shaped support are hinged to the rear supporting column; the self-locking spring is connected with the base frame and the U-shaped support, the self-locking spring acts the elastic effect on the U-shaped support which is further provided with a placement frame matched with the an unmanned aerial vehicle tail cross beam, and the top end of the placement frame is provided with a U-shaped groove; and the unmanned aerial vehicle tail cross beam can be placed in the U-shaped groove. The unmanned aerial vehicle launching frame is of a pure mechanical structure, a control circuit does not need to be controlled, the structure is simple, the weight is low, carrying is convenient, the use range is wide, the requirements for unmanned aerial vehicle launching under different bad conditions can be met, and a launching controller is not needed.

Description

technical field [0001] The invention relates to the field of design of unmanned aerial vehicle launching devices, in particular to an unmanned aerial vehicle launcher. technical background [0002] At present, the launch methods of UAVs can be divided into: sliding takeoff, catapult takeoff, rocket-assisted launch, hand throw launch, air launch and vertical takeoff. [0003] Rolling take-off refers to the process in which the drone is equipped with a rolling device. After the drone is started, the drone takes off on the runway through the rolling device. The advantage of roll takeoff is that the cost of this method is relatively low, the required support equipment is relatively small, and the overload during acceleration is relatively small; its disadvantage is that it has high requirements on the runway ground environment and the landing gear is onboard. At present, the UAVs that use taxiing to take off mainly include the American Predator, the Australian Kindivic UAV and ...

AI Technical Summary

Problems solved by technology

The launchers used in the current rocket-assisted launch technology generally use various electrical control devices such as sensors, which greatly reduces the range of use of the rocket-assisted launch technology in extreme conditions, such as in the case of no electricity, cold areas, rainwater, etc. Weather, etc. may affect the stability of drone launches
