Description

Folding catapult

This creation mainly reveals a type of ejection frame, especially a folding type ejection frame.

When the existing unmanned aerial vehicle is taken off, it must accelerate to the take-off speed like a normal airplane before the aircraft can generate enough lift to take off the aircraft. In order to enable the unmanned aircraft to take off without being restricted by the size or terrain of the site, The ejection frame is usually used to give the unmanned aerial vehicle auxiliary power, so that the unmanned aerial vehicle accelerates to take-off speed and take off in a short time.

Please refer to the Patent No. CN101367438 of the People's Republic of China for the "Unmanned Flight Platform Take-off Ejection System" patent case, which is an ejection system for an unmanned aerial vehicle, which includes a bracket, a slide rail system, a power system and a control system, and a slide rail system. On the rack, the rail system includes a guide rail and a pulley. The power system includes a traction cable, a plurality of pulleys and a winch. After the drone is fixed on the trolley, the trolley is located at one end of the starting end of the guide rail, on the trolley and on the guide rail. The exit end has a pulley, and the traction cable is arranged on the winch through the pulley block. After the winch rotates and the traction cable is stretched, the traction cable can pull the trolley to move in the direction of the exit end of the slide rail, and the drone can obtain the take-off time. The required takeoff speed.

However, the ejection system of such an unmanned aerial vehicle has a fixed shape after assembly, and it is necessary to split into a plurality of parts separately when used for storage, and must be reassembled again when it is to be used next time, if it is not disassembled Direct storage will take up a considerable amount of space, causing space waves Fees are also inconvenient when carrying.

In view of the above-described deficiencies in the conventional structure, the present author is working to design a folding type ejection frame that overcomes all of the disadvantages of the above-described conventional structure.

The main purpose of the creation of the folding type ejection frame is to provide a folding type ejection frame. The ejection frame comprises a plurality of support rods, and the respective support rods can be pivoted or connected relative to each other, so that the ejection frame can be folded and unfolded. When switching between, the two support rods can be placed at an acute angle with the ground, and the unmanned flying vehicle will take off and take off. When the folding state is closed, all the support rods are folded on the same plane, so that the ejection rack is in the storage. The space occupied by the time is minimized.
