Description
Technical Field
The utility model belongs to the technical field of auto-parts technique and specifically relates to an engine bonnet is related to.
Background
The engine of car produces great heat, vibrations and noise at the in-process of operation, produces certain influence to other spare part parts in the car, need install the thermal-insulated aircraft bonnet of engine additional on the engine and effectively protect other parts, adopts double-deck steel sheet thermal-insulated among the prior art among the automobile engine more, and thermal-insulated, anti-vibration and noise reduction effect are limited, can not satisfy the thermal-insulated demand of making an uproar of falling of current engine.
Publication No. CN 104879172A's literature provides a car engine heat-insulating protective cover, the car engine heat-insulating protective cover of this literature, including the metal heat-insulating cover body, the outside of metal heat-insulating cover body be provided with the puigging, the puigging outside be provided with the asbestos board insulating layer, the inboard of metal heat-insulating cover body be provided with a set of circulating pipe of establishing ties together, circulating pipe connect cooling water tank's inlet tube and outlet pipe respectively, this car engine heat-insulating protective cover is thermal-insulated effectual, nevertheless falls to make an uproar and the anti-vibration effect is relatively poor, remains further to improve.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at prior art not enough, provide an engine bonnet, solved among the prior art engine thermal-insulated, fall make an uproar and the relatively poor technical problem of anti-vibration effect.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an engine bonnet, includes thermal-insulated aircraft bonnet body, thermal-insulated aircraft bonnet body is from outer to interior in proper order including thermal-insulated cover skin, thermal-insulated heat preservation and thermal-insulated cover inlayer, thermal-insulated cover outer size is greater than thermal-insulated cover inlayer's size just the edge of thermal-insulated cover inlayer is by thermal-insulated cover outer parcel, it has the reinforcing pad to press the riveting on the outer surface of thermal-insulated cover, be equipped with the bolt hole on the thermal-insulated aircraft bonnet body.
Further, the number of the bolt holes is 3.
Furthermore, the outer layer of the heat shield is made of an aluminum-plated steel plate.
Furthermore, the inner layer of the heat shield is made of stainless steel.
Furthermore, the longitudinal section of the heat shield body is in a C shape.
The utility model has the advantages that:
the utility model provides an engine bonnet, thermal-insulated aircraft bonnet body adopt by outer to interior three layer construction, and thermal-insulated cover surface is pressed and is riveted and is strengthened the pad, and thermal-insulated, fall make an uproar and the anti-vibration effect is better, and the security performance is than higher.
Drawings
Fig. 1 is a schematic view of the overall structure of an engine cover according to the present invention;
FIG. 2 is a cross-sectional view of the engine hood of the present invention taken along plane A-A;
fig. 3 is an enlarged schematic structural diagram of the engine cover of the present invention at a position B.
Detailed Description
The invention is further described with reference to the following figures and examples.
Examples
As shown in fig. 1, 2 and 3, an engine hood comprises a heat-insulating hood body 1, the structure of the heat-insulating hood body 1 is similar to a sandwich structure, the whole body is irregular, the longitudinal section of the heat-insulating hood body is in a C shape, and the heat-insulating hood body 1 sequentially comprises a heat-insulating hood outer layer 2, a heat-insulating layer 3 and a heat-insulating hood inner layer 4 from outside to inside.
Wherein: the outer layer of the heat shield is made of an aluminum-plated steel plate, the aluminum-plated steel plate is EN10346DX53D-DX57D AS120, the thickness of the aluminum-plated steel plate is 0.4mm, and the aluminum-plated steel plate has good heat resistance.
The model of the heat insulation layer is Novaplan 03000, the thickness of the heat insulation layer is 1.0mm, the material of the inner layer of the heat insulation cover is a stainless steel plate, the model of the inner layer is SUS304 JIS G4305-2012, and the thickness of the inner layer is 0.25 mm.
The outer layer 2 of the heat shield is larger than the inner layer 4 of the heat shield in overall dimension, the edge of the outer layer 2 of the heat shield is folded to wrap the edge of the inner layer 4 of the heat shield, and the inner layer 4 of the heat shield is wrapped, so that the three-layer structure ensures that the engine hood body 1 can well insulate heat and reduce noise for the engine.
And a reinforcing pad 5 is pressed and riveted on the outer surface of the heat shield outer layer 2 through a riveting press, the type of the reinforcing pad 5 is SUS JIS G4305-2012, and the thickness of the reinforcing pad is 1.5 mm. The reinforcing pad 5 can prevent the shattering of the heat shield during the operation of the engine.
The outer surface of the heat insulation hood body 1 is provided with bolt holes 6, the number of the bolt holes 6 is 3, the bolt holes 6 are through holes, screws are installed in the through holes and fixed on an engine, and the reinforcing pad 5 is located and fixed on the circumferential edge of one bolt hole 6.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and other modifications or equivalent replacements made by the technical solutions of the present invention by those of ordinary skill in the art should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solutions of the present invention.
