Abstract
An improved automotive casing structure comprises a vehicle body and a chassis, which are integrally formed through rotational moulding process, wherein the chassis is a hollow shell, a metal framework is arranged in the chassis, furthermore, and a metal support from is arranged on the inner edges of the vehicle body along the inner outline of the vehicle body. The improved automotive casing structure simplifies the production process and the die structure, reduces the production cost, lightens the weight of the vehicle body, effectively guarantees the strength and rigidity of an automotive casing, and improves the use safety.
Description
Technical field:
The utility model relates to the car housing structure of various power actuated vehicles such as automobile, elec. vehicle.
Background technology:
The automobile case body was made by glass-felt plastic or iron plate mostly in the past, thereby there are defectives such as Heavy Weight, cost height, complex process, mould be various, for this reason, overall plastic car housing structure with the reinforced plastics making has appearred in the prior art, though this car housing has solved many defectives of above-mentioned steel or iron car housing, but still not enough to some extent aspect intensity and rigidity, thereby be badly in need of improving.
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 simplify manufacture craft and mould structure, reduces production costs, alleviates tare, can effectively guarantee the car housing structure of intensity and rigidity again.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of improved car housing structure comprises vehicle body and chassis, and described vehicle body and chassis are one-body molded by rotational molding technique, and described chassis is a hollow housing, is laid with metallic framework in it, in addition, is provided with metal supporting frames along profile in it in the described vehicle body.
Described metal supporting frames is fixed together with vehicle body from vehicle body is inboard by rivet or bolt, and described metal supporting frames inboard also is provided with decorative layer.
Described metal supporting frames comprises longitudinal ligament frame and cross-tie frame, and described longitudinal ligament frame is along the dual-side setting of profile in the described vehicle body, and described cross-tie frame is arranged respectively along front end, middle part, the rear end of profile in the described vehicle body.
The integrated member of described metallic framework for being welded according to described chassis profile by several metal rods.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
At first, car housing of the present utility model is made of plastics, thereby for the car housing that adopts glass-felt plastic or iron plate to make, not only weight saving satisfied the demand of people to the vehicle lightness, and cost reduces greatly; Simultaneously, owing to be laid with metal supporting frames and metallic framework respectively in vehicle body inboard and inside, chassis, thereby for overall plastic car housing, have better intensity and rigidity, use also more safe and reliable.
Secondly, chassis of the present utility model and vehicle body are one-body molded by rotational molding technique, can improve the globality of car housing on the one hand, more can simplify manufacture craft and mould structure on the other hand, reduce cost of manufacture, enhance productivity.
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, the car crust that provides according to the utility model, comprise vehicle body 1 and chassis 2, vehicle body 1 is one-body molded by rotational molding technique with chassis 2, chassis 2 is a hollow housing, be laid with metallic framework 3 in it, the integrated member of metallic framework 3 for being welded according to chassis 2 profiles by several metal rods, during making, earlier metallic framework 3 is carried out, rotational moulding is carried out in the bottom that then it is installed in the Plastic Rolling Molds with car hull shape, can obtain a vehicle body and the chassis is connected as a single entity and metallic framework is encapsulated in car housing structure in the cavity of chassis behind rotational molding technique.
Be provided with metal supporting frames 4 along profile in it in the vehicle body 1, owing to need to cool off at normal temperatures a period of time typing after moulding system vehicle body rotation molding, at this moment, vehicle body 1 will have a certain amount of shrinkage distortion, therefore, producers before can taking advantage of and moulding the complete cooling and shaping of system vehicle body 1 do not set up metal supporting frames 4 in vehicle body 1 inside, so that vehicle body 1 can tightly be rolled on the metal supporting frames 4 after cooling off fully, thereby improve both bonded assembly fastnesses, avoid occurring loosening.
Metal supporting frames 4 is fixed together with vehicle body 1 from vehicle body is inboard by rivet or bolt, and to influence vehicle body attractive in appearance in order to avoid expose, and attractive in appearance in the compartment, clean and tidy for making simultaneously, metal supporting frames 4 inboards also are provided with the decorative layer 5 that is made of cloth.
Metal supporting frames 4 comprises longitudinal ligament frame 41 and cross-tie frame 42, longitudinal ligament frame 41 has two, and along the dual-side setting of profile in the vehicle body 1, cross-tie frame 42 has the six roots of sensation, and arranges respectively that along front end, middle part, the rear end of profile in the vehicle body 1 be specially: front end Windshield place is provided with one, front end Windshield downside is provided with one, the vehicle body middle part is provided with two, and Windshield place in rear end is provided with one, and rear end Windshield downside is provided with one.To sum up, metal supporting frames is arranged with such frame mode, can reduce consumptive material to greatest extent, reduces cost, can effectively guarantee vehicle body intensity and rigidity everywhere again.
In addition, car door, car bonnet need to make separately, and it can adopt iron plate or steel plate to make moulding, also can be by rotational molding technique moulding respectively, when adopting the rotational molding technique moulding, preferably an also metallic support also is set, to improve the intensity at this place along the car door whole body.
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.
