Abstract

The invention discloses a seat cover based on a heterogeneous material 3D printing technology and a forming method thereof. The seat cover comprises a middle piece, side wing pieces and skirt side pieces, and the two side wing pieces and the two skirt side pieces are symmetrically arranged at the two sides of the middle piece; the middle piece and the side wing pieces are connected through first fasteners, and the seat cover is fixedly connected with a fastening device embedded in seat foaming through first fasteners; the hardness of the parts, far away from the seat foaming side, of the middle piece, the side wing pieces and the skirt side pieces is smaller than that of the parts, close to the seat foaming side, of the middle piece, the side wing pieces and the skirt side pieces; and the middle piece, the side wing pieces, the skirt side pieces and the first fasteners are integrally formed. By means of the seat cover, different cutting pieces of the seat cover and the fasteners are integrally formed by applying the heterogeneous material 3D printing technology, meanwhile, different materials are used at different positions according to the use requirements of the seat cover, the functional requirements of different areas of the cover are met on the basis that the production process of the cover is simplified, and the seat cover has great application prospects.

Description

technical field [0001] The invention belongs to the technical field of automotive supplies, and relates to a seat cover based on heterogeneous material 3D printing technology and a forming method thereof. Background technique [0002] With the development of society, more and more cars have entered every family in China, and the car seat is the most contacted interior of the driver and passengers. Compared with other parts, the comfort of the seat has a great impact on driving And riding have a vital experience. The material used for the seat cover has a direct feedback on the feeling of riding. [0003] The current face cover is mainly composed of three types of materials, namely main fabric, auxiliary fabric and other parts. The main fabric is also called the surface material, which constitutes the main exposed key part of the face cover. This part is in direct contact with the human body, generally the insert, insert upper, and bolster areas, mainly including fabric mat...
