Abstract

The invention discloses a wing connecting structure of a sensor unmanned aerial vehicle, a wing and an unmanned aerial vehicle. The connecting structure comprises a plurality of stepped holes, a plurality of connecting holes, a plurality of connecting pieces and a plurality of plugging elements. The multiple stepped holes are distributed in the skin in the edge strip direction of a wing frameworkand keep away from an antenna unit, the large-diameter ends of the stepped holes sequentially penetrate through a glass fiber plate and a foam plate, and the small-diameter ends of the stepped holes penetrate through a main force bearing plate; the plurality of connecting holes are distributed in the edge strip of the wing framework and are in one-to-one correspondence with the stepped holes; eachconnecting piece is used for fixing the main force bearing plate of the skin on the wing framework through one stepped hole and one connecting hole; and each plugging element is put in one stepped hole, so that the surface of the skin is complete. On the premise of ensuring that the antenna assembly in the wing can work normally, the requirement for structural integrity of a wing is met, the skinand framework connecting process is feasible, and the connecting strength meets the requirement.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and more specifically relates to a wing connection structure of a sensor unmanned aerial vehicle, a wing and an unmanned aerial vehicle. Background technique [0002] The sensor UAV contains sensor components, which can scan within a certain angle range, and is used for the sensor UAV platform. Therefore, it is necessary to ensure that the wave transmission performance within the working radiation range of the UAV meets the requirements, and the reflective layer is electrically continuous. The wing structure must meet the integrity requirements, the skin and skeleton connection process is feasible, and the connection strength meets the requirements. The sensor components of traditional sensor UAVs are independent of the body components. Limited by the requirements of wave penetration, the antenna aperture area is relatively small and the working capacity is limited. If the anten...
