Can there are a variety of, such as rock wool, polyurethane, foamed material etc. in the selection of insulation layer material.And due to Carbon fiber thermal insulation cotton
Material, its thickness are limited by self-characteristic, and the general thickness of general Carbon fiber thermal insulation cotton layer is within 50 millimeters, wherein on the market
The thickness of common Carbon fiber thermal insulation cotton layer is about 10 millimeters, 20 millimeters and 50 millimeters.But for the sky of filling heat insulating wall
The cross-sectional width of chamber 400 is typically up to 50 millimeters, therefore in order to ensure the heat-insulating property of car body, and in actual installation, the 3rd protects
After the warm installation of layer 330, the free end of the 3rd heat-insulation layer 330 exceeds inner liner 200, at this moment using inner liner 200 to protecting
Warm layer is compressed so that heat-insulation layer is tightly arranged in cavity 400.That is, due to thick by market insulation material
The limitation of selection is spent, it is necessary to set insulation by using the mode of three layers of Carbon fiber thermal insulation cotton layer of stack paving in the present embodiment
Layer, so as to effectively increase integral heat insulation thickness degree so that insulation layer thickness is up to 80 millimeters.For example, the first insulation of stack paving
The thickness of layer, the second heat-insulation layer and the 3rd heat-insulation layer is respectively 10 millimeters, 20 millimeters and 50 millimeters, so whole heat-insulation layer
Thickness is i.e. up to 80 millimeters, so as to effectively meet the insulation layer thickness needed for car body.Simultaneously by being stacked different-thickness
Heat-insulation layer can also rationally avoid gaps in market, be purchased with convenient material, improve production installation effectiveness.
In one embodiment, the thickness of first heat-insulation layer 310 is less than the thickness of second heat-insulation layer 320.For example,
The thickness of second heat-insulation layer 320 is less than the thickness of the 3rd heat-insulation layer 330, i.e., the thickness of three layers heat-insulation layer increases successively
Add.For example, the thickness of the 3rd heat-insulation layer 330 is typically chosen the insulation material of 50 millimeters, the milli of the second insulation material selection 20
The insulation material of rice or so.For example, insulation material of the thickness selection of the first heat-insulation layer 310 for 10 millimeters.Specifically, exist
When heat-insulation layer is installed, the first heat-insulation layer 310 of thinner thickness is attached on the perisphere 100 of car body building enclosure first, because
When starting installation, because the internal structure of car body hollow 400 is complex, more raised class formation and corner portion to be present
Point, when being installed in advance using thicker insulation material, because the extensional of insulation material can reduce because thickness is high, so as to unfavorable
In flatly arranging insulation material in car body hollow.When therefore, using the insulation layer material compared with Thin Specs, due to thinner thickness
Insulation material there is preferable extensional, easily realize that bending overlays so that installation attach work be more easy to realize, be advantageous to
Start the various loci of cavity to be closely sticked heat-insulation layer first in installation heat-insulation layer, to reduce fixing clearance, avoid
Heat bridge produces.
Above-mentioned car body building enclosure and its car body, pass through the cavity formed in the perisphere 100 of car body with inner liner 200
Three layers of heat-insulation layer 300 of filling in 400, be on the one hand advantageous to the limitation for overcoming the thickness of market insulation material to select, convenient insulation
Material purchases, in order to lift the installation production efficiency of insulation material.On the other hand by using the different-thickness being stacked
Three layers of heat-insulation layer 300, can effectively meet to be filled up completely with insulation material in the cavity 400 in car body building enclosure will
Ask.The first heat-insulation layer 310, the second heat-insulation layer 320 and the 3rd heat-insulation layer 330 i.e. by being cascading so that insulation
The processing thickness of layer 300 is more than installation thickness when it is filled in cavity 400, so as to effectively lift whole car body heat-insulation layer
Thickness, so that after cavity 400 is filled with insulation material safely, the heat-insulating property of car body can obtain effective lifting.
Heat-insulation layer 300 is set in baroque cavity 400 in order to facilitate realizing, further lifts car body building enclosure
Heat-insulating property.For example, first heat-insulation layer 310 includes multiple the first heat insulating blocks 311 being sequentially connected, second insulation
Layer 320 includes multiple the second heat insulating blocks 321 being sequentially connected, each first heat insulating block 311 and each second heat insulating block 321
Interlaced fold sets.For example, the first heat-insulation layer 310 and the second heat-insulation layer 320 are tailored to multiple heat insulating blocks respectively, i.e., no longer adopt
Disposably it is arranged in cavity 400 with by whole heat-insulation layer, but by multiple first heat insulating blocks 311 cut and multiple
Two heat insulating blocks 321 are attached in the cavity 400 of car body building enclosure respectively.Due to the first heat-insulation layer 310 and the second heat-insulation layer 320
It is cascading when mounted, for the cavity structure that commensurate structure is complicated, the first selected heat-insulation layer 310 and second is protected
The thickness of warm layer 320 is relatively thin, consequently facilitating preferably enabling heat-insulation layer be compacted be attached at cavity 400 everywhere.Compared to
It is integrally formed for heat-insulation layer, is attached using small block heat insulating block advantageously in realization in baroque cavity 400
Carry out effective heat-insulation layer and attach work.Further, since influenceed by working environment and illumination, each position of car body by enthusiasm
Condition is uneven, and when insulation material is en-block construction, due to the heated difference in each position, easily cause local heating to become
Shape, local crowning, stress concentration etc. is caused to influence sticking effect of heat-insulation layer etc..Therefore heat-insulation layer is cut into after bulk can be with
The problem of being effectively prevented from insulation material temperature distortion.
Wherein the second heat insulating block 321 and the first heat insulating block 311 it is interlaced it is folded set and its be in the mode being staggered,
So that the gap between each first heat insulating block 311 of the first heat-insulation layer 310 of composition is staggered the second insulation being stacked at thereon
The effectively gear of block 321 is set.In a preferred embodiment, the medium position of the second heat insulating block 321 and be arranged under it two
The link position of close-connected first heat insulating block 311 is corresponding.That is, by way of misplacing and pasting, can utilize down
One layer of heat insulating block fills up the vacancy of last layer heat insulating block.Because gap area is formed with air cavity, and exist inside and outside car body
The temperature difference, therefore can form the weak region of insulation, causes the generation of heat bridge so that most of heat in car body is from heat bridge region
Transmission.Therefore by way of the heat insulating block that is staggered, the transmission of heat can be effectively prevented, avoids the formation of heat bridge, to add
The heat insulation effect of strong heat-insulation layer.
Further, the 3rd heat-insulation layer 330, example are entirely attached on the second heat-insulation layer 320 after laying in order to realize
Such as, the 3rd heat-insulation layer 330 includes multiple the 3rd heat insulating blocks 331 being sequentially connected, each 3rd heat insulating block 331 and each institute
321 interlaced fold of the second heat insulating block is stated to set.Because the cavity structure gone along with sb. to guard him by car body is influenceed, after using heat insulating block laying
The first heat-insulation layer 310 and the second heat-insulation layer 320 after, still there may be some mounting structure projections not by the first heat-insulation layer
310 and second heat-insulation layer 320 be completely covered, for example, not covered completely by the first heat-insulation layer 310 and the second heat-insulation layer 320
