The invention discloses a cover body structure of a protective cover and a production process, and belongs to the field of special vehicles, the cover body structure comprises a left cover body and a right cover body, the left cover body and the right cover body are each provided with a foam structure layer, a reinforcing rib layer and an outer skin laying layer, and the outer skin laying layers cover the peripheries of the foam structure layers and the reinforcing rib layers. The reinforcing rib layer comprises a foam sandwich, buried iron and an inner skin laying layer, the buried iron is embedded in the two sides of the foam sandwich, and the inner skin laying layer wraps the periphery of the foam sandwich. The outer skin, the foam structure layer and the reinforcing rib layer with the foam sandwich wrapped by the inner skin laying layer are integrally formed through the vacuum infusion technology, so that reinforcing ribs of special-shaped structures and the cover body can be integrally formed, and forming of reinforcing ribs of various modeling curved surfaces such as reinforcing rib turning and arc shapes can be achieved; and the reinforcing rib strength and the product combination degree are not different from those of a plane product. The light weight of the protective cover is met, and meanwhile the structural strength of the protective cover is guaranteed.
本发明公开了一种防护罩的罩体结构及生产工艺,属于特种车辆领域,包括左罩体以及右罩体,左罩体以及右罩体均布置有泡沫结构层、加强筋层以及外蒙皮铺层,外蒙皮铺层包覆于泡沫结构层和加强筋层的外围。加强筋层包括泡沫夹芯、埋铁以及内蒙皮铺层,埋铁嵌设于泡沫夹芯的两侧,内蒙皮铺层包覆于泡沫夹芯的外围。将外蒙皮、泡沫结构层以及由内蒙皮铺层包覆泡沫夹芯的加强筋层通过真空导入工艺一体成型,能够实现异形结构的加强筋与罩体一体成形,包括加强筋转弯、弧形等各个造型曲面的加强筋成型,且加强筋强度以及产品结合度与平面产品比较无区别。满足防护罩轻量化的同时保证了防护罩的结构强度。
