Description

Amphibious vehicle stern pterygoid lamina linking bridge Technical Field The utility model belongs to the technical field of amphibious vehicles, and particularly relates to a stern wing plate connecting bracket of an amphibious vehicle. Background The stern wing plate of the amphibious vehicle is used for controlling the pitch angle of the amphibious vehicle running in water. The angle change of the stern wing plate is controlled by controlling the extension and retraction of the stern wing plate oil cylinder, so that the pitch angle of the amphibious vehicle when the amphibious vehicle runs in water is controlled, and the running posture of the amphibious vehicle in water is ensured. The stern wing plates are usually mounted on a stern wing plate holder which is welded to the frame. Because the existing stern wing plate bracket is provided with two thinner lug plates, the strength is weaker, the stress at the welding seam between the lug plates and the frame is larger, the welding seam is easy to tear, and accidents are caused in the actual use process. The defects of the prior art are that the stern wing plate bracket has weak strength, the stress at the welding seam between the lug plate and the frame is larger, and the problems of fatigue, welding seam tearing and the like are easy to occur. The prior art is named as a miniature amphibious individual combat vehicle and has a publication number of CN110774846A, and the miniature amphibious individual combat vehicle comprises a frame, a support frame, a rotary control panel, a conical sliding-in panel, a rotary table rotary body, an engine, a gearbox, a main wing, a tail wing, a conveyor, a ground pedaling device, a bullet magazine and a shooting controller.
