Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle (UAV) launching platforms, and in particular to a launching platform of an unmanned aerial vehicle (UAV) launching vehicle. Background Art

[0002] Drones are gaining more and more attention for their simple structure, convenient control and high safety performance. Existing small drones are generally made of metal or plastic for cost saving. The legs are also generally made of metal or plastic, or generally do not have legs. In many cases, drones cannot take off autonomously, so additional devices or technologies must be used to help drones take off. Currently, the main ways for drones to take off are taxiing takeoff, vertical takeoff, and catapult takeoff. The drone launcher is placed on a launch vehicle, which is convenient for carrying and can increase the launch height.

[0003] The existing UAV launcher is not convenient for fixing the UAV and the operation is cumbersome. The launch and release of the UAV requires the use of another independent control system, which increases the work cost. When the launch range is reached, manual operation is required, which increases the difficulty of operation. Summary of the invention

[0014] Furthermore, the locking mechanism includes a locking rod and a triangular block. The locking rod is slidably installed on the inner walls on both sides of the sliding hole. A triangular groove is opened at the bottom of the slider. The triangular block is unidirectionally clamped with the triangular groove.

[0019] The winding motor of this solution is started to wind up the wire rope through the winding roller provided with it. Through the cooperation of the pulley, the wire rope drives the ejection slider and the UAV to move forward. After a certain movement, the blocking block squeezes the push rod through the rubber ball, and the push rod pushes the elastic plate downward through the inclined rod. The elastic plate drives the insertion rod to leave the slot. At the same time, the elastic plate drives the two locking rods to move downward through the two connecting rods. The locking rod drives the corresponding triangular block to move downward and leave the triangular slot. Under the elastic force of the reset spring, the slider drives the clamping plate to leave the UAV. The UAV is in the ejection state. After the fixation is suddenly released, it can be launched instantly, and the use effect is good.
