Abstract
The utility model discloses a passenger car engine blimp which comprises an engine blimp body (1). A sealing strip (3) is mounted at the bottom inside the engine blimp body (1). The engine blimp body (1) is filled with sound insulation foamed materials (4). An engine blimp buckle (2) is further arranged on the outer side face of the engine blimp body (1). Compared with the prior art, the sealing strip is arranged in a circle at the bottom of the engine blimp body, therefore, the airtightness between the engine blimp body and a car body floor is enhanced, and noise generated by an engine can be effectively isolated outside a driving cab; the engine blimp body is filled with the sound insulation foamed materials which are provided with holes, and therefore the noise generated by the engine can be effectively absorbed.
Description
Technical field
The utility model relates to a kind of bus engine acoustic cladding, belongs to driving engine acoustic cladding technical field.
Background technology
Flourish along with Domestic Automotive Industry, automobile pollution increases sharply in recent years, and the car noise problem is more and more outstanding, has become topmost noise source in city environment.Internal car noise mainly comes from driving engine, internal car noise is easy to make chaufeur and passenger to produce the psychoreactions such as anxiety, mood be irritated, tired, absent minded, reduce the travelling comfort of automobile, to people's health generation chronic hazard, and brought potential safety hazard for travelling of automobile.
Summary of the invention
The purpose of this utility model is: a kind of bus engine acoustic cladding is provided, solves the larger problem of noise in present bus with front-mounted engine car.
The technical solution of the utility model: a kind of bus engine acoustic cladding, include the driving engine acoustic cladding, driving engine acoustic cladding inner bottom part is equipped with sealing band, in the driving engine acoustic cladding, is filled with noise deadening foam.
Above-mentioned bus engine acoustic cladding, described driving engine acoustic cladding lateral surface also is provided with driving engine acoustic cladding buckle.
Above-mentioned bus engine acoustic cladding, arrange porose on described noise deadening foam.
The beneficial effects of the utility model: the utility model compared with prior art, in driving engine acoustic cladding bottom, be provided with a circle sealing band, increase the leak tightness of driving engine acoustic cladding and body platform, the noise that can effectively driving engine be produced is isolated in outside operator's compartment, sound insulation by filling foamed materials have hole on noise deadening foam in the driving engine acoustic cladding, can absorb the noise that driving engine produces effectively.
The accompanying drawing explanation
Accompanying drawing 1 is inner structure schematic diagram of the present utility model;
Reference numeral: 1-driving engine acoustic cladding, 2-driving engine acoustic cladding buckle, 3-sealing band, 4-noise deadening foam.
The specific embodiment
Embodiment of the present utility model: a kind of bus engine acoustic cladding, as shown in Figures 1 and 2, include driving engine acoustic cladding 1, at driving engine acoustic cladding 1 inner bottom part, one circle sealing band 3 is installed, in driving engine acoustic cladding 1, also be filled with noise deadening foam 4 simultaneously.
At driving engine acoustic cladding 1 lateral surface, also be provided with driving engine acoustic cladding buckle 2.
Also on noise deadening foam 4, arrange simultaneously porosely, circular hole, taper hole, square hole that this hole can be cellular aperture, a plurality of arrays all can.
In use procedure, driving engine acoustic cladding 1 is hinged by hinge with body platform, and driving engine acoustic cladding buckle 2 is corresponding with the buckle on body platform, when killing engine acoustic cladding, by driving engine acoustic cladding 1 and body platform locking, gets final product.
In manufacturing process, driving engine acoustic cladding 1 adopts glass-reinforced plastic material to make, and not only can improve the intensity of driving engine acoustic cladding, and can also effectively alleviate the weight of driving engine acoustic cladding.
Claims (3)
1. bus engine acoustic cladding, it is characterized in that: include driving engine acoustic cladding (1), driving engine acoustic cladding (1) inner bottom part is equipped with sealing band (3), in driving engine acoustic cladding (1), is filled with noise deadening foam (4).
2. bus engine acoustic cladding according to claim 1, it is characterized in that: described driving engine acoustic cladding (1) lateral surface also is provided with driving engine acoustic cladding buckle (2).
