Abstract
The utility model discloses an engine body shielding cover for reducing the noise of the side faces of the engine body, which comprises a machine body, a tightening screw bolt, an engineering plastics sheet and a sponge lining. The utility model is characterized in that the utility model utilizes the characteristics of large damping of the engineering plastics and good sound-absorbing effect of the sponge to reduce the outdision of the noise produced by burning and piston knock. The utility model is made of the engineering plastics sheet in a shape which matches with the shape of the outer surfaces of the engine to make the shapes in consistency. The sponge lining with the sound-absorbing damping effect is stuck on the inner side of the engineering plastics sheet by AB glue or other glue. The engineering plastics sheet is provided with an installing hole corresponding to the installing position of the screw bolt which is arranged on the engine, and is tightly fixed on the outer side of the engine body by the tightening screw bolt. The sponge lining is clamped between the outer side of the engine and the engineering plastics sheet, and the noise of the engine is blocked and eliminated by the sponge which has the damping and sound absorbing effect. The utility model has the advantages of reduction of the noise, light weight, simple structure, easy molding and reliable operation.
Description
Technical field
The utility model relates to a kind of radome, especially produces the engine body radome that noise uses to the body side diffusion at engine body internal-combustion and engine knock.
Background technique
At present, domestic most of engine production merchants satisfy national legislation to the requirement by noise level limit of engine noise, car load, reduce engine noise as far as possible.For this reason, need carry out noise reduction optimization to each system of whole motor, workload is very big, and the construction cycle is long, and cost is high.Because the noise that engine body internal-combustion and engine knock produce has accounted for major component in whole engine noise, by install additional in the body side body radome can effectively reduce the burning and the engine knock noise to external diffusion, thereby effectively reduce the motor total noise of centrifuge.
Summary of the invention
Technical solution of the present utility model is: the purpose of this utility model is to provide a kind of with sponge liner engineering plastics plate and be close to the engine body outer side surface, and utilizing has the foam body of damping sound absorption to exclude noise reduction, to reduce the noise of motor.Comprise body, bolt on.The engine body outer side surface is equipped with engineering plastics plate and sponge liner.The sponge liner sticks on the inboard of engineering plastics plate.The shape in the shape of engineering plastics plate and the engine body outside manufactures.Clip the sponge liner between engine body outer side surface and the engineering plastics plate.The sponge liner is attached to the inboard of engineering plastics plate, and the thickness of engineering plastics plate is not less than 4mm, and the compressed thickness of sponge liner is not less than 2mm, and sponge is adopted the sponge with damping sound absorption.The utility model comprises engineering plastics plate and sponge liner, and the sponge liner is bonded in the inboard of engineering plastics plate, and the whole machine body radome tightens side at body with bolt.Shape according to the engine body side, adopt engineering plastics plate and sponge liner, design body radome, the engineering plastics plate thickness is not less than 4mm, the compressed thickness of sponge liner is not less than 2mm, be directly installed on the engine body surface, the sponge liner is close to body surface, and the external form profile of body radome is consistent with the body side as far as possible.Because of engineering plastics belong to the damping sound absorbing material, sponge has sound-absorbing effect simultaneously, and the noise that therefore can reduce the generation of burning and engine knock significantly is to external diffusion.
Compared with prior art, the beneficial effects of the utility model are:
1, significantly reduces the noise of engine body side;
2, simple in structure, easy for installation;
3, in light weight, meet motor and fall important asking,
4, adopt speed forming method, cost of production is low.

Fig. 2 is the cross-sectional figure of installation lug of the present utility model.
In Fig. 1～Fig. 2: engineering plastics plate (1), sponge liner (2), body (3),
Engineering plastics plate bolt on (4).
Embodiment
Best embodiment of the present utility model is, with the sponge liner that pastes the sound-absorbing damping material in the hard plate, cover in the engine body outer side surface, be fixed tightly in the motor outer side surface with bolt and nut then, the noise that makes motor does not allow its external world that sheds every limit, hard plate manufactures by the engine body profile, and the area that makes it not affect the appearance and take up space more reaches erasure effect again.Comprise engineering plastics plate and sponge liner, use AB glue that the sponge liner is bonded to the inside of engineering plastics plate, noise reducing plate is tightened in bolt on the screw hole that designs, after integral installation is good, other peripheral components are installed again.Engineering plastics plate (1) manufactures by engine body (3) external surface shape with PVC plate or other hard laminate, inner side surface at engineering plastics plate (1) is pasted sponge liner (2), sponge liner (2) is the sponge that the damping sound absorption is arranged, and there have AB glue to paste to be tight, and also available other glue is pasted.Engineering plastics plate (1) is installed on former bolt on (4) the outer corresponding mounting hole that has that is installed on bolt position of motor (3) outer surface, and (4) are fixed tightly in motor (3) outer surface to engineering plastics plate (1) by bolting on.Sponge liner (2) is clipped in engineering plastics plate (1) between engine body (3) outer surface, and is close on engine body (3) outer surface.The thickness of engineering plastics plate (1) is not less than 4mm, and the thickness of sponge liner (2) is not less than 2mm.During installation, sponge liner (1) is close to engine body (3) outer surface, and the external form profile of body radome makes every effort to consistent with body (3) external surface shape during making.Owing to be lined with damping sound-absorbing function in the sponge, so can play the sound insulation noise reduction, lower the engine noise effect, simple in structure, easy to install, cost is low, and the sound insulation noise reduction reaches 2 decibels.Being suitable for motor and using, is a kind of ideal engine body radome.
Claims (4)
1. an engine body radome comprises body, bolts on, and it is characterized in that engine body (3) outer surface is equipped with engineering plastics plate (1) and sponge liner (2).
2. cover the screen cover according to the described engine body of claim 1, it is characterized in that clipping between engine body (3) outer surface and the engineering plastics plate sponge liner (2).
