Embodiment Construction

[0010] Below in conjunction with accompanying drawing description and example, the present invention is described in further detail

[0011] As shown in Figure 1, the front 1, the roof 2, the rear 3, and the side of the vehicle body 4 are heat-synthesized respectively by the above-mentioned method, and then the various parts are connected and fixed to form an airbag-type bus body structure, and the inflation valve is inflated respectively. Just form an airbag type passenger car.

[0012] As shown in Figure 2, before making the airbag body, the model is designed first, and then the mold is made, and then the composite rubber material is placed on the mold and hot-pressed. When hot pressing, the outer layer material can be placed in the mold for hot pressing, and then the drawstring (explosion-proof rib) is heat-sealed to the outer shell layer, and then the inner layer is heat-sealed to all the many drawstrings. This forms a rubber monolithic body shell. An inflation valve is ...

Abstract

The invention discloses a preparing method for vehicle body of airbag, mainly solving shortages of high preparing cost, complicated process, bad crashworthiness, easy distortion, uneasy repair and unsafe staff. The invention selects curtain cloth twined by high-elastic rubber and various fiber so on firstly. The curtain cloth is twisted and sulfured with rubber to form compression resistance material of high and strong elasticity. According to structure size of vehicle component the compression material is cut. Cut materials of high and strong elasticity are glued according to various parts. Finished products of configuration of various parts, angle setting, casting and gluing setting are tested in air tightness. On the internal layer a sealing glue film with high tightness (it is chlorinated butyl rubber in general) is coated. By the invention vehicle weight can be decreased greatly. Power demand and energy consumption can be decreased. Vehicle producing cost can also be decreased. Most importantly, the vehicle body like an airbag can absorb big impact and guarantee staff safety.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a manufacturing process of automobile body materials. Background technique [0002] At present, the body of traditional automobiles is mostly made of metal materials after forging, welding, and then assembled with engines, wheels and other accessories to form a complete vehicle; although the body made of metal has the advantages of high strength and toughness, its cost is high , The manufacturing process is complex, and the biggest disadvantage is poor crashworthiness, easy deformation, difficult repair, and unsafe for drivers and passengers. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a rubber elastic material or PVC composite material made of high elastic rubber and various fiber cords (nylon cords, polyester cords, steel cords, etc.). A manufacturing method of an airbag automobile body that replaces a ...
