The invention discloses a light-emitting skin structure of an automotive trim, which comprises a light-transmitting skin, a light-emitting layer and a fixing framework which are sequentially arranged from outside to inside. The light-emitting layer comprises a net-shaped layer which is of a net-shaped structure formed by fixing a plurality of optical fibers and flexible silk threads in a staggered mode. Each optical fiber comprises an optical fiber core and a light-proof protection layer wrapping the optical fiber core, and a pattern for exposing the optical fiber core is arranged on the light-proof protection layer. The invention further discloses a forming method of the light-emitting skin structure of an automotive trim. The forming method comprises the steps that optical fibers and flexible silk threads are woven into a net-shaped layer; the net-shaped layer is hot-melted to form a pattern required by design; and light-transmitting skin, a light-emitting layer, a flexible cushion layer and a fixing framework are sequentially connected and fixed. According to the structure, the number of layers of the structure and the number of layers of light-transmitting media are reduced, and the light transmittance is improved. The fixing framework can be made of a light-proof material, so that the cost of a light-transmitting ornament is reduced.
本发明公开了一种汽车内饰发光表皮结构,包括由外到内依次设置的透光表皮、发光层和固定骨架,发光层包括网状层,网状层为由多个光纤和柔性丝线交错固定形成的网状结构,光纤包括光纤芯和包裹在所述光纤芯外部的避光保护层,避光保护层上设有裸露出光纤芯的图案。本发明还公开了一种汽车内饰发光表皮结构的成型方法,包括将光纤和柔性丝线编织成网状层;对网状层进行热熔,形成设计所需的图案;依次连接固定透光表皮、发光层、柔性垫层和固定骨架。本发明结构减少了结构的层数和透光介质层数,提高了透光率。固定骨架可采用不透光材料,从而减少透光饰件成本。
