Abstract
The utility model relates to an engine hood cover cap of a light truck. The engine hood cover cap comprises an engine cover cap body, a name board, a rubber ring, an iron tube and a sound-proof device, wherein the engine hood cover cap is mounted on the upper surface of an engine through bolts; the name board is connected to the outer surface of the engine cover cap body in a clamping manner; the sound-proof device is arranged on the inner surface of the engine cover cap body; the outer surface of the iron tube is combined with the inner surface of the rubber ring; the outer surface of the rubber ring is connected to a mounting hole in the engine cover cap body in a clamping manner. Through the technical scheme, the nose reduction performance can be effectively improved.
Description
Technical field
The utility model belongs to light card field, specifically refers to light card engine bonnet structure.
Background technology
The principal element that produces car noise is aerodynamic force, mechanical drive, electromagnetism three parts.Structure, can be divided into motor noise (being roughness noise), chassis noise (connection that is noise of driving system, each parts coordinates the noise causing), electric equipment noise (cooling fan noise, automobile current generator noise), body noise (noise causing as unreasonable in the installation of body structure, moulding and annex and noise source are imported structural vibration that noise in car and automobile each several part vibration pipeline the excite body panel noise composition internal car noise to radiation in operator's compartment into by various acoustics approach).Wherein driving engine is the Main Noise Sources of automobile, its contribution accounts for the more than 1/2nd of car noise, for reducing automotive engine noise level, on existing light card, generally adopt the technological means such as exhaust muffler, electromagnetic fan clutch, Double-layer oil bottom shell are set, these technological means noise reductions are better but cost is higher.
Utility model content
The purpose of this utility model is the demand in order to meet driving engine noise reduction, and existing light card engine bonnet structure is proposed to improve technical scheme, by the technical program, can improve anti-acoustic capability by actv..
The utility model is achieved through the following technical solutions:
A kind of light card engine bonnet, includes engine case body, nameplate, rubber ring, iron pipe and sound arrester; Described engine bonnet is installed on driving engine upper surface by bolt; On the outside face of described nameplate clamping and engine case body, described sound arrester is arranged at the inside face of engine case body; The outside face of described iron pipe is combined with the inside face of rubber ring; The outside face of described rubber ring is connected in the mounting hole on engine case body.
The mounting hole of described engine case body is groove structure, and the bottom surface of groove is provided with through hole, and the diameter of described through hole is less than the diameter of groove.
The inside face of described groove structure is cone platform shape.
The outside face of described rubber ring is I-shape construction, is connected in the through hole of mounting hole; The maximum outside diameter of described rubber ring is less than the minimum diameter of groove structure.
The outside face of described iron pipe and the inside face of rubber ring are interference fit.
On described engine case body, be provided with at least 5 mounting holes.
Advantage applies of the present utility model is in the following areas:
1, application engine cap assembly in light truck-type first, the engine case assembly that is installed on driving engine upper surface is handsome in appearance, has covered wire harness and the support of driving engine upper surface simultaneously, has promoted the exquisite technological level of car load;
2, by increasing engine case assembly and Sound-proof material 5, can effectively isolate a part of engine noise, can absorb again a part of engine noise, thereby improve the NVH level of car load.
3, increase engine case assembly is lower with respect to the cost such as exhaust muffler, electromagnetic fan clutch is set, and more can improve car load class simultaneously.
