Abstract
The invention belongs to the technical field of automobile parts, and particularly relates to an automobile engine hood which comprises a hood plate, wherein the hood plate adopts a double-layer structure and comprises a top-layer plate and an inside muffler orifice plate; the top-layer plate adopts a pyramid-type structure; the muffler orifice plate is an arc-shaped plate; a plurality of uniformly distributed conical noise reducing units are arranged between the top-layer plate and the muffler orifice plate; a layer of sound absorbing sponge is arranged on the inner wall surface of the top-layer plate; and a drainage pattern is formed on the outer wall surface of the top-layer plate. The automobile engine hood is simple in structure, relatively high in dust, water and oil resistance, and relatively good in sound absorbing and noise reducing performance.
Description
Technical field
The invention belongs to technical field of automobile components, be specifically related to a kind of automotive hood.
Background technology
Car bonnet is positioned at above engine case, driving engine can produce very large sound in operation process, in order to solve the impact of engine noise on surrounding environment, car bonnet generally arranges the structure of hollow bumps, play deadening, but effect is very limited, the noise of driving engine still can have considerable influence to surrounding environment, and start the important effect of the another one of cover to be exactly that dustproof and waterproof is grease proofing, protection driving engine, but the car bonnet of existing structure is owing to arranging bulge-structure, its cover body shape end face is irregular, the effect causing dustproof and waterproof grease proofing is not good.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned defect, and provide dustproof and waterproof oil preventing performance better and a kind of automotive hood that sound-deadening and noise-reducing is effective, structure is simple.
The technical scheme that the present invention solves the employing of its technical matters is as follows:
A kind of automotive hood, comprise cover plate, described cover plate is double-decker, comprise top plate and inboard muffling hole plate, top plate is rib tapered structure, and muffling hole plate is arc, is provided with multiple uniform taper noise reduction unit between top plate and muffling hole plate, top plate internal face is provided with one deck acoustical cotton, and face of keeping away outside top plate is provided with drainage lines.
Further, the large one end of described noise reduction unit diameter is towards top plate, and the noise reduction unit conical surface is helical structure, and helical structure is provided with multiple hole, fills silencing cotton between noise reduction unit.
Further, described top plate edge upwarps formation sluice way, is connection structure bottom sluice way.
Further, the cold tapered tapering of described top plate is 0.5 °-3 °.
Further, described top plate end face is provided with waterproof layer.
Beneficial effect acquired by the present invention is: adopt such scheme, pyramidal structure top plate makes the dust on cover body easily be washed out by water in conjunction with drainage lines, and says along edge's drainage, and its surface texture is regular, improve dustproof and waterproof grease proofness, noise reduction unit, in conjunction with muffling hole plate and silencing cotton, is carried out attraction noise reduction to the noise of driving engine, is greatly reduced noise, structure is simple, be convenient to manufacture, provide cost savings, economy is higher.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is cross section structure schematic diagram of the present invention.
Wherein: 1 is top layer version, 2 is muffling hole plate, and 3 is noise reduction unit.
Detailed description of the invention
A kind of automotive hood as shown in Figure 1, comprise cover plate, cover plate is double-decker, comprise top plate 1 and inboard muffling hole plate 2, top plate 1 is rib tapered structure, the cold tapered tapering of top plate 1 is 3 °, muffling hole plate 2 is arc, multiple uniform taper noise reduction unit 3 is provided with between top plate 1 and muffling hole plate 2, the large one end of noise reduction unit 3 diameter is towards top plate 1, the internal face of top plate 1 is provided with one deck acoustical cotton, noise reduction unit 3 conical surface is helical structure, helical structure is provided with multiple hole, silencing cotton is filled between multiple noise reduction unit 3, noise sound wave weakens after acoustical panel 2, enter into multiple noise reduction unit 3 subsequently, helical structure through taper noise reduction unit 3 stops segmentation, weakened to decompose by the aperture of noise reduction unit 3 again and absorbed by silencing cotton, reach noise reduction object, noise reduction is better, the outer of top plate 1 keeps away face waterproof layer, but also be provided with drainage lines, in conjunction with rib tapered structure, by good for profit water conservancy diversion, the edge of top plate 1 upwarps formation sluice way, it is connection structure bottom sluice way, connection structure is connected with driving engine place, water conservancy diversion lines coordinates with sluice way, profit is avoided to deposit oil and water carrying-off, flowing water can also wash away dust simultaneously, driving engine place is made to keep clean, dustproof and waterproof function of draining the oil is better.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification sheets of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
