Description
Technical field
It the utility model is related to a kind of car engine cover.
Background technology
Engine soundproof effect is an important indicator for weighing car mass, and soundproof effect often represents the shelves of automobile
Secondary, way general at present is to lay Sound-proof material at the motor cover back side, but the sound deadening of Sound-proof material is limited, with people couple
The pursuit more and more higher of automobile quietness, the motor cover with more preferable soundproof effect should be developed.
Utility model content
In order to solve problem present in background technology, the utility model provides a kind of low-noise automobile motor cover, should
Motor cover has superior soundproof effect.
To reach above-mentioned purpose, the utility model adopts the following technical scheme that：
A kind of low-noise automobile motor cover, including Shell Plate, it is characterised in that：The top of Shell Plate is provided with from Shell Plate
Upper raised sandwich plate, the surrounding of the edge opposite shell plate of sandwich plate inside contract, and are hollow between sandwich plate and Shell Plate
Space；The sound panel to raise up is provided with sandwich plate, the front end of sound panel is along with being provided with inclined gear between sandwich plate
Plate, the center of baffle plate eliminate area for resonance, and resonance eliminates in area and is provided with multiple dampening foams plates being fixed on baffle plate, sound insulation
Multiple noise reductions projections are provided with the upper surface of plate, the raised surface of noise reduction, which is set, is pasted with Sound-proof material.
Dampening foams plate is fixed on baffle plate by way of stickup.
Multiple dampening foams plate size shapes are different.
The both sides that resonance eliminates area are respectively arranged with reinforcement connection sheet, strengthen connection sheet one end and are fixed on sound panel, separately
One end is fixed on Shell Plate.
The beneficial effects of the utility model are：
1st, by the dual sound insulation of hollow space between the Sound-proof material and sandwich plate and Shell Plate of sound insulation plate surface, so as to have
There is preferable soundproof effect；
2nd, noise caused by motor cover and motor resonance is eliminated by being provided with special resonance elimination area.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings
Fig. 1 is the overall schematic of automobile motor lid described in the utility model；
Embodiment
Explanation and embodiment are further described to the utility model below in conjunction with the accompanying drawings：
Embodiment 1
As shown in figure 1, a kind of low-noise automobile motor cover, including Shell Plate 1, the top of Shell Plate 1 are provided with from shell
Raised sandwich plate 2 on plate 1, the surrounding of the edge opposite shell plate 1 of sandwich plate 2 inside contract, sandwich plate 2 and Shell Plate 1 it
Between be hollow space.
The sound panel 6 to raise up is provided with sandwich plate 2, the front end edge of sound panel 6 is inclined with being provided between sandwich plate 2
Oblique baffle plate 3, the center of baffle plate 3 eliminate area 7 for resonance, and resonance eliminates in area 7 and is provided with multiple dampening foams plates 5, multiple to disappear
The size shape of sound cystosepiment 5 is different, and dampening foams plate 5 is pasted onto on baffle plate 3.The both sides that resonance eliminates area 7 are set respectively
Have and strengthen connection sheet 8, strengthen the one end of connection sheet 8 and be fixed on sound panel 2, the other end is fixed on Shell Plate 1.
