Description

Hot air backflow preventing structure and commercial vehicle

Technical Field

The utility model relates to a hot-blast proof reflux structure and commercial car belongs to the commercial automobile field.

Background

The hot wind reflux unit that prevents in current commercial car mostly is rubber cushion or sponge piece, and the assembly of upper end is in driver's cabin floor panel beating department, and the lower extreme laminating is in engine radiator department, nevertheless has following defect:

1. the rubber material is soft as a whole, and can deform along with the jolt of a cab in the driving process, so that the hot wind backflow prevention device fails, the sponge block is easy to accumulate dust and water, the service life is short, and the appearance quality is poor.

2. The effective shielding area of the hot wind backflow prevention device is small, and the effect is poor.

Disclosure of Invention

To the problem that above-mentioned prior art exists, the utility model provides a hot-blast proof structure that flows back, hot-blast proof backflow is effectual, is difficult for deposition ponding, longe-lived, and appearance quality is good.

The utility model also provides an install commercial car of this solar heat protection wind backflow structure.

In order to realize the purpose, the utility model discloses a prevent hot-blast backward flow structure, hang the skin under installing support, deep bead body, layering, this internal pre-buried nut plate of deep bead, hang the skin down and pass through layering and this body coupling of deep bead, the installing support passes through bolt and this body coupling of deep bead, and the installing support is installed on the floor panel beating.

As an improvement, the wind deflector body adopts a PHC honeycomb plate.

The air baffle comprises a first air baffle body and a second air baffle body, wherein the first air baffle body is provided with a first air inlet, a second air inlet and a second air inlet, and the first air inlet and the second air inlet are respectively provided with a second air inlet and a second air outlet.

As a further improvement, the first pressing strip and the second pressing strip are both made of metal materials.

As an improvement, the lower hanging skin adopts any one of TPE, XPE, EVA and PVC.

Additionally, the utility model also provides a commercial car, install on the commercial car hot-blast prevention backflow structure.

Compared with the prior art, the utility model discloses a prevent hot-blast backward flow structure, appearance quality is good, and the structure is light, and intensity is high, can laminate closely with peripheral, and the hot-blast backward flow that fully prevents the radiator and blow off leads to the heat balance inefficacy to the engine compartment.

FIG. 2 is an exploded view of the assembly of the present invention;

FIG. 3 is a schematic view of the present invention in cooperation with a front floor insulation mat;

in the figure: 1. the mounting bracket comprises a mounting bracket body 2, a wind shield body 3, a first pressing strip 4, a lower hanging skin 5, a second pressing strip 6, a bolt 7 and a front floor heat insulation pad.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is for purposes of illustration only and is not intended to limit the scope of the present disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.

As shown in fig. 1, 2 and 3, the hot wind backflow prevention structure comprises a mounting support 1, a wind shield body 2, a pressing strip and a lower hanging skin 4, wherein a nut plate is embedded in the wind shield body 2, the lower hanging skin 4 is connected with the wind shield body 2 through the pressing strip, the mounting support 1 is connected with the wind shield body 2 through a bolt 6, and the mounting support 1 is mounted on a floor metal plate.

As an improvement of the embodiment, the wind deflector body 2 is made of paper honeycomb, PP honeycomb or aluminum honeycomb processed by a PHC honeycomb plate process, and the nut plate is embedded in the wind deflector body 2, so that no visible standard part exists on an exposed surface, and the appearance quality is improved.

The batten comprises a first batten 3 and a second batten 5 as improvement of the embodiment, and the first batten 3 and the second batten 5 are fixed on the wind deflector body 2 through bolts 6. The first pressing strip 3 and the second pressing strip 5 are made of metal materials, such as carbon steel, nonferrous metals and the like, and can ensure that the lower hanging skin 4 is tightly attached to the wind shield body 2.

As the improvement of embodiment, under hang skin 4 and be soft high temperature resistant non-metallic material, like non-metallic material such as TPE, XPE (chemical crosslinking polyethylene expanded material), EVA, PVC, can guarantee that parts such as hot-blast reflux prevention structure and radiator, water tank are flexible contact, prevent that the driver's cabin from beating to lead to parts to damage.

Finally, the utility model also provides a commercial car, install on the commercial car solar heat protection wind backflow structure, it is concrete, solar heat protection wind backflow structure passes through installing support 1 to be fixed on driver's cabin floor panel beating, guarantees that solar heat protection wind backflow structure's outward appearance does not have any visual standard, has promoted appearance quality.

In addition, in order to perfect the boundary of the wind deflector body 2, the matching clearance between the wind deflector body 2 and the front floor heat insulation pad 7 is controlled to be about 3mm, and the anti-backflow effect of the hot air backflow prevention structure is improved to the maximum extent.

The utility model discloses a prevent hot-blast backward flow structure, appearance quality is good, and the structure is light, and intensity is high, can laminate closely with peripheral, fully prevents that the hot-blast backward flow that the radiator blew off to the engine compartment and lead to the heat balance inefficacy.
