Abstract
The utility model provides a heat insulation structure for an automobile top cover, which comprises a first heat insulation layer, a second heat insulation layer and a fabric layer; and the first heatinsulation layer, the second heat insulation layer and the fabric layer are arranged in sequence. The automobile top cover heat insulation structure has lower cost under the condition of the same heat insulation property; the automobile top cover heat insulation structure is mainly made of foam materiel, so that the weight is lighter and the empty weight of the automobile can be reduced; moreover, the occupy volume is small; the automobile top cover heat insulation structure is favorable for vehicle transportation; and the transportation cost is reduced.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of automobile top-cap heat insulation structural.
Background technology
Existing automobile is parked in the open, and is sultry hard to bear in the car because roof structure is not heat insulation when especially a day hot sun is exposed to the sun, and is the most vexatious thing of vast automobile driver.
At occurring in nature, the mode of interchange of heat has three kinds: convection current, conduction and radiation.Three kinds of modes always interact, simultaneous, and be to carry out interchange of heat by height to lower along the gradient fields of temperature.Car roof top cover cover panel generally is the interchange of heat that stops conduction pattern.
Present automobile car internal head cover cover panel is for resisting stubbornly, resist stubbornly is to be that the lining that strengthens sheet material such as structure polyurethane (PU) foamed plastic and surface constitutes by material, the coefficient of thermal conductivity of its polyurethane (PU) foamed plastic is 0.019W/ (m.k)～0.023W/ (m.k), and the heat that produces in the time of can stoping sun direct projection roof is transmitted in the car by resisting stubbornly.
But, hard cap need heat sheet material, put into the die part of mould then together with lining, the punch of mould partly separates after a period of time with die part one matched moulds subsequently, and this structure is unfavorable for reducing the weight of unit body and the cost of operation.
The utility model content
The utility model is in order to overcome above-mentioned the deficiencies in the prior art, and the utility model provides a kind of automobile top-cap heat insulation structural that can reduce production costs greatly.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile top-cap heat insulation structural is provided, and it comprises first thermal insulation layer, second thermal insulation layer and precoat, and described first thermal insulation layer, second thermal insulation layer and precoat set gradually.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer is the EVA layer, and second thermal insulation layer is the PU layer.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer and second thermal insulation layer are the PU spongy layer.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer and second thermal insulation layer are foam works or honeycomb structure thing.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer and second thermal insulation layer are respectively foam works and honeycomb structure thing.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer and car internal head cover bonding.
The scheme that the utility model solves further technical matters is: described first thermal insulation layer, tight bond between second thermal insulation layer and the precoat.
Compared to prior art, automobile top-cap heat insulation structural of the present utility model is under identical heat-proof quality condition, and cost is lower; Because this automobile top-cap heat insulation structural institute constituent material mainly is a foamed materials, weight is lower, can alleviate the deadweight of vehicle, and it is little to take volume, is beneficial to vehicular transport, reduces traffic cost.
Description of drawings
Fig. 1 is the structural representation of automobile top-cap heat insulation structural of the present utility model.
Fig. 2 is the running condition scheme drawing of automobile top-cap heat insulation structural of the present utility model.
The specific embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
As shown in Figure 1, automobile top-cap heat insulation structural of the present utility model comprises EVA layer 11, PU layer 12 and precoat 13, and described EVA layer 11, PU layer 12 and precoat 13 set gradually.Described EVA layer 11 is Ethylene/vinyl acetate foams, and described PU layer 12 is isocyanurate foams.
The coefficient of thermal conductivity of described PU layer 12 is 0.022W/ (m.k), and the coefficient of thermal conductivity of EVA layer 11 is 0.038W/ (m.k).
The color of described precoat 13 matches with tone in the car, only EVA layer 11 directly need be sticked on during use on the top cover in the car.
The running condition scheme drawing of automobile top-cap heat insulation structural of the present utility model as shown in Figure 2.
The foam density of PU is 15～30Kg/m3, the foam density of EVA is 30～50Kg/m3, use in the prior art to resist stubbornly with the density that strengthens the structure polyurethane foamed plastic be 470～530Kg/m3, density between two kinds of cover panels differs 10 times, and such structure makes unit body weight saving.
The textural association of described EVA layer 11 in addition and PU layer 12 also can be simple PU sponge or other similar foam works, or the honeycomb structure thing.Above material has softness equally, and the advantage that density is little can be utilized the cavity body in himself structure, realizes that every the heat-insulating function, the part overall weight is less simultaneously.
Automobile top-cap heat insulation structural forming process of the present utility model is comparatively simple, during moulding, environmental protection glue evenly need be coated with, pressurization is composited then, do not need to develop forming mould, need the exploitation forming mould than existing resisting stubbornly: punching block, glass punching block are compared, and have saved the part cost of development greatly.
Automobile top-cap heat insulation structural of the present utility model is in light weight, and the vehicle of certain load-carrying can transport more automobile top-cap heat insulation structural thing; On the other hand, automobile top-cap heat insulation structural softness, tiling type are molded into certain shape unlike resisting stubbornly, have saved transport space, have reduced the traffic cost of part simultaneously.
