Abstract
The utility model discloses a combined car body structure which includes a moulded car body shell formed by rotational moulding and a metal skeleton distributed along the inner profile of the moulded car body shell. The metal skeleton is fixedly connected with the moulded car body shell by a rivet or a bolt. The structure leads the car body to have the advantages of simple manufacture, lower production cost, improved intensity and lightened weight, etc.
Description
Technical field:
The utility model relates to the body structure of various power actuated vehicles such as automobile, elec. vehicle, the body structure of particularly a kind of plastics and metallic framework combination.
Background technology:
Existing auto body is made by glass-felt plastic or iron plate mostly, thereby has following shortcoming: 1, tare is heavy, can not satisfy people to vehicle weight-saving demand, has also aggravated the consumption of the energy simultaneously; 2, the expensive and complex manufacturing technology of the prices of raw and semifnished materials, mould are various etc. causes productive costs very high; 3, the energy-absorbing buffering ability of vehicle body is relatively poor, and its strength under shock and yield tensile strength all await improving; 4, fiber glass reinforced plastics (FRP) body does not have the distortion restorability, produces when distortion in case vehicle body is collided, and all needs usually to change or by the external force reparation.
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, and can guarantee intensity again, alleviates tare and have the unitized body structure of distortion restorability.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of unitized body structure comprises that moulding of rotation molding made body shell and the metallic framework of outline in the system body shell is moulded on the edge.
Described metallic framework is fixed together by rivet or bolt and the described system body shell of moulding.
Described metallic framework inboard also is provided with internal decorative layer.
Described internal decorative layer is a trimming cloth.
Described metallic framework is brandreth, steelframe or aluminium alloy frame.
Described metallic framework comprises vertical skeleton and horizontal skeleton, and described vertical skeleton is along the dual-side setting of moulding the system body shell, and described horizontal skeleton is arranged respectively along front end, middle part, the rear end of moulding the system body shell.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
At first, body shell of the present utility model is made of plastics, several metallic frameworks are only set up as supporting along profile in the plastic casing in inside, therefore for the vehicle body that vehicle body all adopts glass-felt plastic or iron plate making, not only weight saving, satisfied the demand of people, and cost reduces greatly, improved the price competitiveness of product the vehicle lightness.Simultaneously, the body shell of moulding system also makes it have the distortion restorability, and it is collided and produces when distortion at vehicle body, can restore to the original state automatically by patterned heat, and does not need by external force.
Secondly, the system body shell of moulding of the present utility model adopts the rotational molding technique moulding, can process at one time, and makes simply, and used number of molds seldom thereby has further reduced the productive costs of vehicle body when making.In addition, the energy-absorbing function of moulding the system body shell is apparent in view, and impact resistance is strong, adds inside and is provided with metallic framework and supports, and makes it form the body structure that plastics and metallic framework make up, thereby has improved the strength under shock of vehicle body and yield tensile strength etc. greatly.
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 unitized body structure that provides according to the utility model, comprise that moulding of rotation molding made body shell 1 and the metallic framework 2 of outline in the system body shell 1 is moulded on the edge, metallic framework 2 by rivet or bolt and mould the system body shell 1 be fixed together, when affixed, rivet or bolt be from the installed inside of metallic framework 2, and to influence vehicle body attractive in appearance in order to avoid expose.Simultaneously, attractive in appearance in the compartment, clean and tidy for making, metallic framework 2 inboards also are provided with the internal decorative layer 3 that is made of trimming cloth.
As mentioned above, mould system body shell 1 and behind rotation molding, need to cool off at normal temperatures a period of time typing, at this moment, body shell 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 body shell 1 do not set up metallic framework 2 in body shell 1 inside, so that body shell 1 can tightly be rolled on the metallic framework after cooling off fully, thereby improve both bonded assembly reliability, avoid occurring loosening.Metallic framework 2 can adopt brandreth, steelframe or aluminium alloy frame, can certainly adopt other to meet the bracing frame of intensity and rigidity requirement.Metallic framework 2 comprises vertical skeleton 21 and horizontal skeleton 22, wherein, vertically skeleton 21 has two, and is provided with respectively along the dual-side of moulding system body shell 1, and laterally skeleton 22 has the six roots of sensation, and along mould the system body shell 1 front end, middle part, rear end arrange respectively, be specially: front end Windshield place is provided with one, and front end Windshield downside is provided with one, and the vehicle body middle part is provided with two, Windshield place, rear end is provided with one, and rear end Windshield downside is provided with one.To sum up, vertically skeleton 21 and horizontal skeleton 22 are arranged with such frame mode, can reduce consumptive material to greatest extent, reduce cost, can effectively guarantee vehicle body intensity 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 internal metal rack 4 (as shown in Figure 1) also is set, to improve the intensity at this place along the car door whole body; And the body shell 1 that comprises outer covering piece in body bottom panel, the vehicle body etc. except that car door and car bonnet adopts the rotational molding technique integral one-step molding.
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.
