Abstract
The embodiment of the invention discloses an electric automobile battery box, and relates to the technical field of electric automobiles. The electric automobile battery box is used for enhancing the thermal insulation performance of the battery box. The battery box comprises a battery box shell, the internal surface layer and the external surface layer of the battery box shell adopt a glass fiber reinforced plastic, and the interlayer of the battery box shell adopts a foamed plastic. The battery box of the embodiment of the invention has a good thermal insulation performance.
Description
Technical field
The present invention relates to electric vehicle engineering, relate in particular to battery case of a kind of electric automobile and preparation method thereof.
Background technology
At present, the battery case of electric automobile adopts panel beating material more.But, adopt the heat-insulating property of battery case of this material poor.
Summary of the invention
The embodiment of the present invention provides battery case of a kind of electric automobile and preparation method thereof, to strengthen the heat-insulating property of battery case.
The embodiment of the present invention adopts following technical scheme:
A battery case for electric automobile, comprising: battery case housing, and the inside and outside surface layer of described battery case housing adopts fiberglass reinforced plastics, and the interlayer of described battery case housing adopts foamed plastics.
A manufacture method for the battery case of electric automobile, comprising:
Adopt semi-rigid mould and the processing of vacuum resin leading-in technique to obtain battery case housing, wherein, the inside and outside surface layer of described battery case housing adopts fiberglass reinforced plastics, and the interlayer of described battery case housing adopts foamed plastics.
Battery case of the electric automobile of the embodiment of the present invention and preparation method thereof, the inside and outside surface layer of described battery case housing adopts fiberglass reinforced plastics, the interlayer of described battery case housing adopts foamed plastics, due to these materials, makes battery case in heat-insulating property, obtain enhancing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the schematic diagram of battery case of the electric automobile of the embodiment of the present invention;
Fig. 2 is the processing technology figure of battery case of the electric automobile of the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, the battery case of the electric automobile of the embodiment of the present invention comprises battery case housing, and wherein, the inside and outside surface layer 11 of described battery case housing and 12 adopts fiberglass reinforced plastics, and the interlayer 13 of described battery case housing adopts foamed plastics.
Wherein, for further strengthening heat-insulating property, the thickness of the inside and outside surface layer of described battery case housing is 2mm, and the surface thickness of described battery case housing is 4mm.
Owing to having adopted heat insulating material, thereby the heat-insulating property of battery case is strengthened.The battery case of available technology adopting panel beating material, higher in the expense of batch production rear mold, and also the insulation property of panel beating material are poor.And, to compare with adopting the battery case of other materials, the battery case weight of the same volume of employing panel beating material is larger.And the battery case of the embodiment of the present invention, for panel beating material, weight is lighter, light and flexible.
Wherein, described battery case housing adopts semi-rigid mould and the processing of vacuum resin leading-in technique.Technological process shown in concrete Jing Guo Fig. 2 obtains.In the technological process shown in Fig. 2, mainly comprise die treatment (comprise mould prepare, utilize carbon fibre fabric dress mould mold closing, check mould air-tightness, mould is vacuumized etc.), case material process (comprise by resin and curing agent mix, by vacuum resin import mould, to mold heated, solidify, finally demould), three key steps such as processing detection, finally obtain goods.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; can expect easily changing or replacing, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of described claim.
Claims (4)
