[0002] In recent years, the electric vehicle industry has developed rapidly. At present, the body of electric vehicles is generally made of glass fiber reinforced plastic or metal sheet metal, and the chassis is all made of metal structure. The weight of the vehicle itself is relatively heavy, which has great influence on the battery life of the vehicle. Larger impact, the impact resistance of the car is poor, and the safety factor is low.
Some domestic manufacturers have done a lot of research on the lightweight of the car body. For example, the published patent (CN102601905A) mentioned a one-time molded three-layer plastic car shell. The plastic shell has light weight and good impact resistance. and other advantages, but there are few domestic innovations in plasticizing technology for automobile chassis

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 , figure 2 As shown, a rotomolded automobile chassis includes a chassis main body 1 . The chassis body 1 includes a surface layer and a central foam layer 2, the surface layer includes an inner surface layer 3 and an outer layer 4, a cavity is provided between the outer layer 4 and the inner surface layer 3, and the central foam layer 2 It is in the cavity between the outer skin 4 and the inner skin 3 . Therefore, the chassis body 1 of the present invention has a three-layer structure including the outer skin 4 , the central foam layer 2 and the inner skin 3 .
[0020] The chassis main body 1 includes a positioning structure 5, and the positioning structure 5 is provided with mounting holes 6 fixed to the vehicle body. The chassis main body 1 is provided with a rib structure 7 and a kiss structure 8 for enhancing rigidity and stre...

The invention belongs to the technical field of new energy vehicle, and particularly relates to a rotational moulding vehicle chassis which comprises a chassis body. The chassis body comprises surface layers and a center foaming layer, wherein the surface layers comprise an inner surface layer and an outer surface layer; a cavity is formed between the outer surface layer and the inner surface layer; the center foaming layer is positioned in the cavity between the outer surface layer and the inner surface layer; reinforcing rib structures and kiss-type structures, which are used for strengthening rigidity and strength, are arranged on the chassis body; a positioning structure is arranged on the chassis body; mounting hole sites fixed with a vehicle body are arranged on the positioning structure. Through the adoption of the rotational moulding formation technology, the vehicle chassis is formed in one time; the production process is reduced; the production cost is lowered; the weight of the vehicle is reduced; the energy consumption is lowered; the impact strength of the vehicle is enhanced; the sound insulation effect of the vehicle is enhanced.
