The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle and a catapult thereof.The unmanned aerial vehicle comprises a catapulting frame, one side of the catapulting frame is fixedly connected with an air cylinder, the output end of the air cylinder is fixedly connected with a boosting rod, the side, away from the air cylinder, of the boosting rod is fixedly connected with a connecting block, and a connecting groove is formed in the connecting block. A push plate drives a push handle to move, the push handle drives a connecting rod to move, the connecting rod drives an ejector block to move, the ejector block ejects a clamping block into a fixing groove, a third spring drives a mounting block to restore, a moving plate drives two first gear plates to move upwards, and the two first gear plates drive gears to rotate; and two second gears drive two second gear plates to restore, so that the two second gear plates drive two square plates to move, the two square plates are separated from the insertion grooves, the insertion blocks continue to drive the unmanned aerial vehicle to move according to inertia, and the situation that the ejection effect of the unmanned aerial vehicle is reduced due to fixation of the supporting plates and the insertion blocks is avoided.

    本发明涉及无人机领域,具体的说是一种无人机及其弹射器,包括弹射架,弹射架一侧固定连接气缸,气缸输出端固定连接助推杆,助推杆远离气缸一侧固定连接连接块,连接块内开设有连接槽。通过推板带动推把移动,推把带动连接杆移动,使连接杆带动顶块移动,并使顶块将卡块顶入固定槽内,使第三弹簧带动安装块复原,使移动板带动两个第一齿轮板向上移动,两个第一齿轮板带动齿轮转动,两个第二齿轮带动两个第二齿轮板复原,使两个第二齿轮板带动两个方形板移动,从而使两个方形板与插槽分离,而插块会根据惯性继续带动无人机移动,从而避免因支撑板和插块的固定导致无人机的弹射效果下降。
