, the sound absorbing layer being made of porous materials, and the sound absorbing layer close to the side of the engine, because be molded it is oriented described in
The protrusion of engine side evagination and be rough surface.
Further, the sound absorbing layer is made of hard polyurethane foam.
Further, the protrusion is spaced apart multiple tracks, and makes the sound-absorbing layer surface in wavy.
Further, the protrusion is in pyramid.
Further, the shell is made of plastics.
Further, in being formed with storage tank on the shell, the sound absorbing layer is flush-mounted in the storage tank.
Further, interval is placed with the fixed column that multiple free ends are bulb shape in the storage tank, corresponds to each
The fixed column is equipped with the mounting hole that can be sheathed on the fixed column bottom, and the hole of the mounting hole on the sound absorbing layer
Diameter is less than the outer diameter of the fixed column bulb shape end.
Compared with the existing technology, the utility model has the advantage that：
(1) engine decorative lid described in the utility model by the way that the sound absorbing layer being made of porous materials is arranged, and is being inhaled
Choppiness structure is constructed in sound-absorbing layer, can be effectively isolated and be absorbed the noise that engine generates, so as to improve the NVH of engine
Energy.
(2) sound absorbing layer is made of hard polyurethane foam, and the sound-absorbing effect of sound absorbing layer can be improved.
(3) sound-absorbing layer surface is in wavy, and be capable of selectivity crosses noise filtering, and improves using effect.
(4) storage tank is set, can be convenient for clamping sound absorbing layer.
(5) sound-absorbing slot can be improved in the clamping stability on shell in setting fixed column.
The another object of the utility model is to propose a kind of vehicle, including is formed with the vehicle body of enging cabin, and in institute
State and be installed with engine in enging cabin, be provided at the enging cabin be buckled on it is as described above above the engine
Engine decorative lid.
The vehicle of the utility model had the advantage that compared with the existing technology with engine decorative lid it is identical, herein not
It repeats again.

Specific implementation mode
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.
The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
Embodiment one
The utility model is related to a kind of engine decorative lids, and as shown in fig. 1, which includes shell 1, with
And be connected in shell 1 close to sound absorbing layer 2 on 3 one side end face of engine, being made of porous materials, and sound absorbing layer 2 leans on
It is bordering on the side of engine 3, is rough surface because being molded the protrusion 21 of oriented 3 side evagination of engine.
Specifically, the shell 1 in the present embodiment is made of plastics, and sound absorbing layer 2 is made of hard polyurethane foam, with
It being capable of preferably sound insulating and absorbing using the multiple-void structure characteristic of its material itself.Above-mentioned raised 21 for arranged for interval in suction
Multiple tracks in sound-absorbing layer 2, to make 2 surface of sound absorbing layer be in wavy, the noise that can be so generated to engine 3 carry out absorption resistance
Every can have good noise reduction.Certainly, protrusion 21 is in addition to using the above structure, can be configured as pyramid, this knot
Structure can also play the role of sound insulating and absorbing.
It in the present embodiment, fixes in the installation on shell 1 for ease of sound absorbing layer 2, as shown in fig. 1, is formed on shell 1
There is storage tank, sound absorbing layer 2 is i.e. in storage tank.Further, to improve the mounting stability of sound absorbing layer 2, such as institute in Fig. 2
Show, interval is placed with the fixed column 4 that multiple free ends are bulb shape in storage tank, and corresponds to each fixed column 4, in sound absorbing layer
2 are equipped with the mounting hole that can be sheathed on 4 bottom of fixed column, and the aperture of mounting hole is less than the outer diameter of 4 bulb shape end of fixed column,
It is detached from fixed column 4 to avoid sound absorbing layer 2.The free end of fixed column 4 is configured to ball head structure, sound absorbing layer 3 can be convenient in accommodating
Being embedded in slot, meanwhile, when sound absorbing layer 3 is because being adsorbed with dust, moisture etc., its sound absorption effect is caused to reduce and need replacing
When, ball head structure can also be convenient for the disengaging at 3 self-retaining column 4 of sound absorbing layer, can smoothly tear out sound absorbing layer 2 out of storage tank.
It, need to be according to the test knot of its noise in the present embodiment for the engine of different type of machines 3 when specifically used
Structure is designed optimization to the integral hardness of 2 polyurethane material of sound absorbing layer, density and the size in gap, optimal to realize
Sound insulating and absorbing effect.Meanwhile the parameters such as the Wave crest and wave trough height to wavy shaped configuration, wave wavelength and wave density also can basis
Concrete application conditions need to adjust accordingly, and retain low frequency exhaust voice that pointedly can eliminate high-frequency noise, reach
Preferable using effect.
This engine decorative lid is by using the polyurethane material with noise elimination function and combines wavy shaped configuration, can be effective
The noise that ground separate absorption engine 3 generates, and the NVH performances of engine 3 can be improved.
Embodiment two
The utility model is related to a kind of vehicles comprising be formed with the vehicle body of enging cabin, and installed in enging cabin
There is engine 3, the engine decorative lid as described in embodiment one being buckled on above engine 3 is equipped at enging cabin.This
The vehicle of embodiment can carry out the noise that engine 3 generates effective by the way that the engine decorative lid such as embodiment one is arranged
Ground separate absorption, to which vehicle riding comfort can be improved.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection domain within.
