Problems solved by technology
[0005] The purpose of the present invention is to provide a tripping mechanism for the trolley of the unmanned aerial vehicle ejection frame. The linkage and disengagement between the transmission device and the trolley are precisely controlled through the tripping mechanism, which solves the problem that the motor of the ejection frame cannot be used after the UAV is ejected. Immediate braking causing damage to the catapult rack

Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0023] like figure 1 As shown in the UAV ejection frame, the UAV ejection frame includes a slide rail 01, a trolley 05, a motor 02, and a transmission pulley 03. The UAV 06 is placed on the trolley 05, and the motor 02 transmits the traction force through the transmission pulley 03 and the transmission belt 4. Pass it to the trolley 05, and the trolley 05 is locked and disengaged from the transmission belt 4 through the release mechanism. The drone 06 is placed on...

The invention relates to the technical field of launching of unmanned aerial vehicles and particularly discloses a launching cradle cart tripping mechanism for an unmanned aerial vehicle. In the initial stage of launching the unmanned aerial vehicle, a slot of a movable fixture block is clamped on a front limiting bolt of a vertical plate under the action of two springs, and meanwhile, a transmission belt splint and transmission teeth of the transmission belt are in a mutually fastened state; at the moment, the launching cradle tripping mechanism and the transmission belt are in a completely locked state; when a cart and the unmanned aerial vehicle slide to the top end of a launching cradle, the movable fixture block collides with a striker and then quickly bounces backward to the position of a limiting rod, so that the slot of the movable fixture block is completely disengaged from the front limiting bolt; and meanwhile, under the double action of the transmission belt and the movable fixture block, a connecting rod is rotated to enable the transmission belt splint to move forward and downward, so that the transmission belt splint and the transmission teeth of the transmission belt are completely disengaged, and the launching cradle cart is completely disengaged from transmission. The tripping mechanism disclosed by the invention has the advantages that the tripping mechanism can be locked with and disengaged from the transmission belt through the movable fixture block and can realize accurate tripping within a very short period of time in the launching process.
Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a tripping mechanism for a trolley of an unmanned aerial vehicle ejection frame. Background technique [0002] The ejection modes of the existing ejection racks on the market mainly contain pneumatic, steel wire traction, rubber band elastic force and the like. [0003] Among them, the pneumatic ejection frame pushes the piston rod by the high-pressure gas in the cylinder, and pushes out the cylinder together with the UAV in an instant, so that the UAV can obtain a certain take-off speed; The UAV obtains a certain take-off speed; the rubber band elastic type catapult uses the elastic force of the rubber band or spring to pull the car and the UAV, so that the UAV obtains a certain take-off speed. [0004] For the existing ejection racks currently on the market, the power devices used are not unique, and mainly include methods such as pneumatic transmission, motor...
