Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] The UAV rotating ejection frame of the present invention comprises a base 1 , a rotating rocker arm 2 and a torsion spring 3 . The base 1 is composed of a tripod 101, a support rod 102, a fixed disc 103 and a limit block 104, as figure 1 As shown, the described tripod 101 is an adjustable mechanism, and is fixedly welded or screwed on the disc 103 together with the lower end of the support rod 102; the length and the angle of the three supporting legs of the adjustment tripod 101 can be varied The launch direction and launch pitch angle of the man-machine. A limit block 104 is fixed near the top of the support rod 102, usually the limit block 104 is a rubber material, and a fixed circular support is set at point A on the support rod 102 at a certain distance from the lower surface of the limit block 104. Plate 107; the lower surface of the limit block 104 has a cir...

Abstract

The invention discloses a rotary ejection frame for small-sized unmanned aerial vehicles, belonging to the aeronautical machinery technical field. The rotary ejection frame comprises a launcher base,a rotary rocker arm and a torsion spring, wherein two ends of the torsion spring are respectively fixed with the base and the rotary rocker arm; a tripod with height and angle adjustable is arranged on the base; a flying gripping mechanism, a releasing mechanism and a counterweight mechanism are arranged on the rotary rocker arm; and the formed rotary ejection frame has the advantages of simple structure and convenient operation. Moreover, the rotary ejection frame is small in occupied area, rapid to unfold and withdraw. Compared with common linear-type ejection frames, the size of the rotaryejection frame is greatly reduced, which provides convenience for the use of small-sized unmanned aerial vehicles.

Description

technical field [0001] The invention belongs to the technical field of aviation machinery, and in particular relates to an ejection launching frame of an unmanned aerial vehicle, which is especially suitable for launching small unmanned aerial vehicles. Background technique [0002] The traditional UAV ejection system can be divided into hydraulic ejection, air pressure ejection, elastic ejection, electromagnetic ejection and so on according to the different forms of launch energy. Small UAVs with a take-off speed of less than 25m / s and a take-off weight of less than 100kg usually use the elastic ejection method. No matter what kind of ejection method is used, the energy stored in the energy storage device must be converted into mechanical kinetic energy to accelerate the UAV to a safe take-off speed on a linear slide rail of a certain length. Therefore, the length of the slide rail determines the ejection. The minimum size of the system. The traditional ejection system is...
