Abstract
The present invention relates to a kind of cabin heat shield and automobiles, cabin heat shield includes the flange that the base plate being connected for the cabin rear wall with engine nacelle, lower edge extend back with the front of the base plate along the inclined plate portion being connected and from the upper edge in the inclined plate portion, for being connected with the sealing strip mounting platform on windscreen wiper decoration, the inclined plate portion gradually upwardly extends the flange from rear to preceding.Cabin heat shield proposed by the present invention can slow down the aging speed of sealing strip and windscreen wiper decoration after front shroud.
Description
Technical field
The present invention relates to automobile engine nacelles, and in particular to a kind of cabin heat shield and automobile.
Background technique
High temperature can be generated when turbocharger operation, causes the air themperature around turbocharger also very high, and high temperature is empty
Gas will affect the normal use of other components in enging cabin, therefore the vehicle with turbocharger needs to alleviate heat evil and asks
Topic.As depicted in figs. 1 and 2, supercharger heat shield 9 on the one hand is set to stop in the periphery of turbocharger 8 in the prior art
On the other hand the diffusion of heat arranges airflow channel in enging cabin 1, start the air introducing of Chinese herbaceous peony in running car
Heat is taken away in cabin 1, to realize cooling.Turbine increasing can be alleviated to a certain extent by above-mentioned two ways
The heat damage of depressor 8, but in the windscreen wiper decoration 3 for finding 1 rear portion of enging cabin in actual use of automobile with before
5 aging of sealing strip is very fast after cover, and service life does not meet design requirement.
As depicted in figs. 1 and 2, by analyzing existing automobile, the turbocharging of advance heel row engine is found
Device 8 is located at the rear portion of enging cabin 1, and the top of the cabin rear wall 2 of enging cabin 1 is equipped with gutter channel 6, and windscreen wiper decoration 3 is installed
On gutter channel 6, sealing strip 5 is then mounted on the sealing strip mounting platform 4 of 3 front of windscreen wiper decoration after front shroud, and front shroud is total
It is covered on enging cabin 1 at 7, the overlap joint of sealing strip 5 is behind the rear portion of front shroud assembly 7 and front shroud to form sealing.After automobile stops,
The high temperature air that turbocharger 8 distributes can diffuse up, and high temperature air flow to front shroud assembly 7 and takes with sealing strip 5 after front shroud
It connects position slowly to accumulate and then spread down, this results in sealing strip 5 and 3 long-time of windscreen wiper decoration after front shroud to be immersed in high temperature
In air, since sealing strip 5 is rubber parts after front shroud, windscreen wiper decoration 3 is immersed in meeting in high temperature air by plastic part for a long time
The aging of sealing strip 5 and windscreen wiper decoration 3 after acceleration front shroud, reduces the use longevity of sealing strip 5 and windscreen wiper decoration 3 after front shroud
Life.
Summary of the invention
The purpose of the present invention is to propose to a kind of cabin heat shield, which can slow down sealing strip and rain after front shroud
Scrape the aging speed of decoration.
A kind of cabin heat shield of the present invention, including be connected for the cabin rear wall with engine nacelle base plate, under

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
A kind of cabin heat shield as shown in Figure 3 and Figure 4, including what is be connected for the cabin rear wall 2 with engine nacelle 1
Base plate 10, lower edge extend back with the front of base plate 10 along the inclined plate portion 11 being connected and from the upper edge in inclined plate portion 11
Flange 12, flange 12 for being connected with the sealing strip mounting platform 4 on windscreen wiper decoration 3, inclined plate portion 11 from it is rear to preceding gradually
It upwardly extends.By adopting the above technical scheme, base plate 10 plays heat-insulated effect, and inclined plate portion 11 plays heat-insulated and to high temperature air
Carry out the effect of water conservancy diversion；Turbocharger is formed by high temperature air under the guidance in inclined plate portion 11, can reduce stream of hot air
After to front shroud at sealing strip 5, high temperature air can be reduced and assembled at sealing strip 5 after windscreen wiper decoration 3 and front shroud, reduce and occur
A possibility that 5 long-time of sealing strip is immersed in high temperature air after windscreen wiper decoration 3 and front shroud, the heat-blocking action of cabin heat shield
The evil of heat suffered by sealing strip 5 after windscreen wiper decoration 3 and front shroud can be reduced with guide functions, to seal after slowing down front shroud
The aging speed of item 5 and windscreen wiper decoration 3.
As an improvement reducing high temperature air in order to reduce the gap between flange 12 and front shroud assembly 7 and flowing to front shroud
Possibility at sealing strip 5 afterwards, flange 12 are equipped with the lug boss 13 that upward convex and length extends in left-right direction.Further, convex
Portion 13 is played along the front of flange 12 along extension.Retain safety clearance between lug boss 13 and front shroud assembly 7, so that lug boss
13 do not influence the opening and closing of front shroud assembly 7.
As a preference, cabin heat shield is equipped with metallic reflection outer layer.Metallic reflection outer layer can be high temperature resistant aluminium
