Problems solved by technology
[0002] The locking devices of modern UAV ejection and launch mostly adopt electronic control or hydraulic control for locking and automatic unlocking, especially the requirement of automatic unlocking during ejection, the required structure is more complicated, the weight is larger, and the installation space is larger
At the same time, the electric control or hydraulic control unlocking system is adopted. The design of the electric control and hydraulic control wiring and pipe layout makes the whole structure limited by electric power and hydraulic pressure, and the installation and debugging are more complicated.

Embodiment Construction
[0018] The technical solution of the present invention is further described below, but the scope of protection is not limited to the description.
[0019] Such as Figure 1-2 As shown, the device is in a locked state and is mainly composed of a rotating arm 1, an intermediate arm 4, a triangular arm 7, a counterweight 6, a tension spring 2, a spring latch 8, a fixed shaft 3, a rotating shaft 5, and a frame body 9. The rotating arm 1 and the triangular arm 7 are hinged on the frame body 9 through two fixed shafts 3 and can rotate around the fixed shafts 3 . The middle arm 4 articulates the rotating arm 1 and the triangular arm 7 through two rotating shafts 5 . The counterweight 6 is hinged on the triangular arm 7 through the rotating shaft 5 . The extension spring 2 is connected to the fixed shaft 3 of the hinged rotating arm 1 while being connected to the triangular arm 7 . The spring latch 8 is compressed on the triangular arm 7 by the elastic force of the compression spri...

A light-weight locking device for unmanned aerial vehicle ejection mainly comprises a rotating arm, a middle arm, a triangular arm, a balancing weight, an extension spring, fixing shafts, a spring cotter and a frame body, the rotating arm and the triangular arm are hinged to the frame body through the two fixing shafts and can rotate around the fixing shafts, the rotating arm and the triangular arm are hinged through the middle arm through two rotating shafts. The balancing weight is hinged to the triangular arm through the rotating shaft, one side of the extension spring is connected to a fixed shaft hinged to the rotating arm, the other side of the extension spring is connected to the triangular arm, the spring cotter is pressed on the triangular arm through elastic force of the compression spring, and the functions of locking and automatic unlocking by setting acceleration are achieved. The device is simple in structure, light in weight and small in needed installation space, meanwhile, a pure mechanical structure is adopted, and the design of wiring and pipe arrangement of electric control and hydraulic control is eliminated, so that the whole structure is not limited by electric power and hydraulic pressure; in addition, through the dead point characteristic of the connecting rod, the stress environment of the structure is greatly optimized, and the reliability of the device is enhanced.
Description
technical field [0001] The invention belongs to the technical field of unmanned aerial vehicle launching, and in particular relates to a lightweight locking device for unmanned aerial vehicle ejection. Background technique [0002] The locking devices of modern UAV ejection and launch mostly adopt electronic control or hydraulic control for locking and automatic unlocking, especially the requirement of automatic unlocking during ejection, the required structure is more complicated, the weight is larger, and the installation space is larger. At the same time, the electric control or hydraulic control unlocking system is adopted, and the design of the electric control and hydraulic control wiring and pipe layout makes the whole structure limited by electric power and hydraulic pressure, and the installation and debugging are more complicated. Therefore, there is an urgent need to provide a light-weight locking device that does not use electronic control and hydraulic pressure,...
