The invention discloses a helicopter pedal electromagnetic shielding and dustproof structure, belongs to the field of helicopter tail rotor and airplane wheel operation control, and aims to solve the problems that a traditional dustproof cover is easy to age and has temperature requirements on a working environment. Comprising a dust cover pressing plate, a pedal supporting arm, a dust cover body and a main body frame. The dustproof cover body is sewn to be in a conical cylinder shape, two first long-strip-shaped holes are formed in the main body frame, a second long-strip-shaped hole is formed in the dustproof cover pressing plate, the fixing ring is connected to the upper portion of the pedal supporting arm in a sleeving mode, the dustproof cover body is connected to the pedal supporting arm in a sleeving mode, and the closing-in end of the dustproof cover body is bound to the fixing ring through the binding band. The edge of the flaring end of the dust cover body is clamped and fixed through the dust cover pressing plate and the sliding plate. The electromagnetic shielding effect is achieved by utilizing the material characteristics of the conductive cloth, and the dustproof effect is achieved by utilizing the structure of the protective cover body. The cable is simple in structure, easy to manufacture, not prone to aging, wide in adaptive temperature range, resistant to acid atmosphere, salt spray corrosion, damp heat and mould.
一种直升机脚蹬电磁屏蔽及防尘结构,属于直升机尾桨及机轮操纵控制领域,本发明为了解决传统防尘罩易老化,对工作环境有温度要求的问题。包括防尘罩压板、脚蹬支臂、防尘罩本体和主体框架;防尘罩本体缝制呈锥筒形,主体框架上设有两个第一长条孔,防尘罩压板上设有第二长条孔,固定环套接在脚蹬支臂的上部,防尘罩本体套接在脚蹬支臂上,并通过捆绑扎带将防尘罩本体的收口端绑在固定环上,防尘罩压板和滑板将防尘罩本体的扩口端边缘夹合固定。利用导电布自身材料特性起到电磁屏蔽的作用,利用防护罩本体自身结构起到防尘作用。本发明结构简单、制作容易,不易老化、适应温度范围为大,耐酸性大气、耐盐雾腐蚀、耐湿热、耐霉菌。
