specific Embodiment

[0033] Such as Figure 1 to Figure 3 Shown, a kind of synchronous unfolding system of ejecting unmanned aerial vehicle folding wing, comprises the connection unit of left and right wing (such as Figure 4 shown), fix the upper and lower cover plates of the wing connection unit in the vertical direction (such as Figure 5 and Image 6 shown), synchronously deploying the gear train actuating mechanism (such as Figure 8 shown) and the gear shaft retaining plug (as Figure 10 shown).

[0034] image 3 The left and right wing connection unit bodies shown are made of polypropylene material, where the size of the channel for housing the compression spring is determined by the size of the spring, which in turn is sized according to the elastic restoring force required for wing deployment to make sure. The radius of the through hole of the gear shaft is 8mm, and there are cylindrical pin through holes with a radius of 1mm every 90 degrees in the circumferential direction, such as...

Abstract

The invention relates to a wing synchronous unfolding system of catapult unmanned aerial vehicle folding wings and a using method. The wing synchronous unfolding system comprises two wing extending units and a synchronous gear mechanism, and the wing extending units of left and right wings are enabled to rotate by 0-90 degrees around axis of a main gear through elastic resilience generated by compressing springs in the process of folding the wings to complete a folding and unfolding function of the wings; left and right cover plates are fixedly connected with a fuselage through retaining blocks with lugs; and by designing the synchronous gear mechanism, synchronous unfolding of the left and right wings is guaranteed. In order to reduce structural weight and improve flying efficiency, weight of each unit is reduced on the premise that structural strength is guaranteed. By the wing synchronous unfolding system, accurate positioning and reliable unfolding of the left and right wings of a folding wing unmanned aerial vehicle can be realized reliably, and catapult success rate of the unmanned aerial vehicle is increased, so that reliability of the whole unmanned aerial vehicle is improved substantially. The wing synchronous unfolding system has the advantages that the system is reasonable in design, easy to implement, low in cost and simple and quick in folding mode, and the wings after being folded are regular and attractive in appearance and convenient to carry.

Description

technical field [0001] The invention belongs to the design technology of a folding-wing unmanned aerial vehicle for catapult take-off, and in particular relates to a wing synchronous unfolding system and a use method of a folding wing of an unmanned aerial vehicle for ejection. Background technique [0002] Flying robots with ejected folding wings have many advantages over traditional missiles and large unmanned aerial vehicles. Compared with traditional missiles, it is small in size and strong in maneuverability, suitable for anti-terrorism and urban warfare. Compared with reconnaissance unmanned aerial vehicles, it has the advantages of miniaturization, individual portability, rapid access to combat areas, and flexible tactics. Compared with offensive unmanned aerial vehicles, it can accurately drop bombs, reduce innocent casualties, reduce the negative impact of war, and has the characteristics of good portability, low cost, and strong concealment. It is worth noting th...
