Abstract
The utility model relates to a double-layer plastic automobile body structure comprising an automobile main body. The automobile main body comprises a hollow plastic shell integrally molded by a rotational moulding technique; and a plurality of reinforcing support ribs are formed between the inner side wall body and the outer side wall body of the hollow plastic shell. In the structure, as the hollow plastic shell is integrally molded by adopting the rotational moulding technique at one time, the moulding is convenient, and the manufacture is simple; simultaneously as the plastic shell is also moulded with a plurality of reinforcing ribs, the strength of the automobile body is ensured; and in addition, the automobile structure also has the effects of sound insulation and heat insulation.
Description
Technical field:
The utility model relates to the body structure of various power actuated vehicles such as automobile, elec. vehicle, particularly a kind of double-layer plastic vehicle body structure.
Background technology:
The disclosed a kind of plastic body structure of car of China utility model patent ZL01142849.X, it is decomposed into top cover, base, left-hand door, right car door, front apron, back shield six big parts with vehicle body, and each parts is formed in conjunction with the sandwich component of formation and aluminum alloy inner support and the foamed plastic of being located in the sandwich component by sheet in the rigid plastic and outer plate.The shortcoming of this structure is: though 1, the aluminum alloy inner support is set in sandwich component can proof strength, has also increased cost and manufacture craft simultaneously; 2, sheet and outer plate split production in the rigid plastic, not only moulding bothers, and also needs inside and outside is fixed together to form sandwich component after packaging the aluminum alloy inner support, and entire making process is very loaded down with trivial details.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of and can guarantee intensity, can simplify manufacture craft again, reduces production costs, alleviates tare and have the double-layer plastic vehicle body structure of effects such as sound-insulating and heat-insulating.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of double-layer plastic vehicle body structure comprises the vehicle body main body, and described vehicle body main body comprises a hollow plastic housing by the rotational molding technique global formation, is formed with many between the inboard wall body of described hollow plastic housing and the outside wall body and strengthens brace rod.
Foam layer in the middle of being folded with in the described hollow plastic housing.
The thickness of foam layer is 30～100mm in the middle of described, and the wall thickness of described hollow plastic housing is 5～10mm.
The width of described reinforcement brace rod is 25～100mm, highly is 20～80mm.
Foam layer is selected Polyurethane foam liquid or fluent material for use in the middle of described, injects after coagulation by high pressure or low pressure plastic pouring machine in described hollow plastic housing and forms.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
At first, vehicle body main body of the present utility model adopts the double-layer plastic structure, be about to the vehicle body main body and make the hollow plastic housing, and foam layer in the middle of folder is established in the hollow plastic housing, thereby for steel or iron vehicle body main body, it can alleviate tare significantly, satisfies the demand of people to the vehicle lightness, and reduction reduces cost to the consumption of the energy; Simultaneously, this structure also makes vehicle body main body of the present utility model have sound insulation, heat-insulating effect.
Secondly, because the hollow plastic housing adopts the rotational molding technique integral one-step molding, thereby convenient formation, and can save follow-up affixed, packaging technology, make simple; Simultaneously, owing to also form some reinforcement brace rods in the hollow plastic housing, thereby on the basis of saving aluminum alloy inner support, cost-cutting, effectively guaranteed the intensity of vehicle body main body.
Description of drawings:
Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
With reference to Fig. 1, with the automobile is example, vehicle body main body 1, base 2, car door (meaning not shown in the figures) and car bonnet 3 are all separately made, wherein, vehicle body main body 1 adopts the double-layer plastic structure, promptly is made up of hollow plastic housing 11 and clamping middle foam layer 12 within it, base 2, car door and car bonnet 3 are made with iron plate or steel plate respectively and are formed, during installation, by rivet each parts is riveted, thereby form complete vehicle body.
As mentioned above, vehicle body main body 1 comprises one by the hollow plastic housing 11 of rotational molding technique global formation and be folded in middle foam layer 12 in this hollow plastic housing 11, also be formed with many in the hollow plastic housing 11 and strengthen brace rod 14, the inside and outside both sides of strengthening brace rod 14 join with the inboard wall body 111 and the outside wall body 112 of hollow plastic housing respectively, to increase the intensity of vehicle body main body 1, during making, reinforced rib 14 is with inner wall 111 and outer wall 112 rotation moldings.And on the make during plastic layer, then select Polyurethane foam liquid or fluent material for use, in hollow plastic housing 11, inject foam layer 12 in the middle of after this liquid or fluent material solidify, forming by high pressure or low pressure plastic pouring machine.
The thickness of foam layer 12 is 30～100mm in the middle of described, and the wall thickness of hollow plastic housing 11 is 5～10mm.The width of described reinforcement brace rod 14 is 25～100mm, highly is 20～80mm.
The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
