The top layer of chassis body of the present invention is to pass through Plastic Rolling Molds outside steel structure framework by the one-time formed hollow plastic product of rotational molding technique.
Center of the present invention foaming layer is the center foaming layer adding PU expanded material in the cavity on top layer.
Center of the present invention foaming layer is the center foaming layer by disposable rotational foaming material rotational moulding.
Inserts of the present invention is located at chassis body to be needed to install at part, and inserts has mounting hole site.
Inserts of the present invention is connected with needing the steel structure framework at installation part, and inserts has mounting hole site.
Chassis body of the present invention is provided with multiple inserts, and inserts has mounting hole site；Also including inserts fixed plate, inserts fixed plate is fixing with inserts to be connected, and described inserts fixed plate and multiple inserts are integral type structure.
Chassis body of the present invention is provided with multiple inserts, and inserts has mounting hole site, and the plurality of inserts is separate type structure, is distributed on chassis body.
Compared to the prior art the invention have the characteristics that and beneficial effect:
1, it is provided with steel structure framework in chassis, keeps the rigid on chassis, extend chassis service life.
2, rotation molding disposable to automobile chassis top layer, can simplify production process, improves production efficiency, reduces cost.
2, top layer internal cavity adds middle foaming layer, alleviates the weight of automobile, reduces energy consumption, saves source environmental protection.
3, on the one hand middle foaming layer enhances rigidity, on the other hand adds the effect of the energy-absorbing of automobile chassis, reduces impact, and the soundproof effect of automobile can be more preferably.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further details.
As shown in Figures 1 to 4, a kind of rotational-molded automobile chassis with steel structure framework, including chassis body 1, described chassis body 1 includes top layer 2, steel structure framework 3 and center foaming layer 4；Being provided with cavity in described top layer 2, described center foaming layer 4 is in top layer internal cavities；Described steel structure framework 3 is located in top layer 2, and steel structure framework 3 includes total profile skeleton 5, the cross bar 6 being connected on total profile skeleton 5 and vertical pole 7.On chassis body 1, end face and bottom surface are respectively provided with the reinforcing rib structure 8 of convex type and groove type；Chassis body 1 is provided with the inserts 9 installing parts.
The top layer 2 of chassis body 1 of the present invention is by the one-time formed hollow plastic product of rotational molding technique in the outer Plastic Rolling Molds of passing through of steel structure framework 3.
Center of the present invention foaming layer 4 can be added PU expanded material in the cavity on top layer and form.Can also be by the center foaming layer 4 of disposable rotational foaming material rotational moulding.
Need to install at part as it is shown in figure 5, inserts 9 of the present invention is located at chassis body 1, inserts 9 has mounting hole site 10.When needs install small parts on chassis body 1, directly inserts 9 is set on chassis body 1 top layer 2, small parts is arranged in the mounting hole site 10 of inserts 9.
As shown in Figure 6, inserts 9 of the present invention is connected with needing the steel structure framework 3 at installation part, and inserts 9 has mounting hole site 10.When need to install the bigger auto parts and components of the stress such as vehicle body on chassis body 1 time, inserts 9 is connected with the steel structure framework 3 in chassis body 1, inserts 9 can be connected more firm with automobile chassis main body 1, it is provided that enough power, makes the parts such as vehicle body firmly connect with chassis body 1.
As shown in Figure 6, Figure 7, chassis body 1 of the present invention is provided with multiple inserts 9, and inserts 9 has mounting hole site 10；Also including inserts fixed plate 11, inserts fixed plate 11 is fixing with inserts 9 to be connected, and described inserts fixed plate 11 is integral type structure with multiple inserts 9.The location comparison installed when parts is intensive, the stress such as body of a motor car are such as installed heavier, during the parts of mounting hole site 10 comparatively dense, inserts fixed plate 11 is used to be fixed together by the inserts 9 being closely located together, when chassis surface 2 is fluted, inserts fixed plate 11 and chassis body 1 surface groove compact siro spinning technology.Making inserts 9 can bear bigger power, parts are more firmly connected with chassis body 1.
As shown in Figure 5, chassis body 1 of the present invention is provided with multiple inserts 9, mounting hole site 10 is had on inserts 9, the plurality of inserts 9 is separate type structure, is distributed on chassis body 1, when installing parts and more disperseing, inserts 9 only need to be fixed on automobile chassis 1 and need to install the position of part, need not link together these inserts 9, save material, it is to avoid automobile chassis is overweight.
It is provided with steel structure framework 3 in chassis body 1 of the present invention, maintains the rigid of chassis body 1, extend the service life of chassis body.The disposable rotation molding in automobile chassis top layer 2, can simplify production process, improves production efficiency, reduces cost.Top layer 2 internal cavity adds middle foaming layer 4, and rotational moulding top layer 2 and middle foaming layer 4 alleviate the weight of automobile simultaneously, reduces energy consumption, saves source environmental protection.Middle foaming layer 4 one aspect enhances rigidity, on the other hand adds the effect of the energy-absorbing of automobile chassis 1, reduces impact, and the soundproof effect of automobile can be more preferably.
