Abstract
The utility model relates to an automobile part, in particular to a lower protecting sound-proof housing of an automobile engine. The utility model aims at provide a lower protecting sound-proof housing of an engine which can protect the engine from outside damage and control the engine noise. The sound-proof housing particularly comprises a cambered main body which is arranged below the engine. The main body comprises three layers of a sound reducing layer, a sound-proof layer and a protective layer from up to down. The sound reducing layer and the protective layer are fixedly connected. The lower protecting sound-proof housing of an automobile engine in the utility model is simple in structure and low in cost. The lower protecting sound-proof housing of an automobile engine can not only protect the engine from damage by outside foreign matters to ensure the normal working of the engine, but also have the sound-proof and sound-reducing effect and can reduce the noise pollution to the outside world of the engine.
Description
Technical field
The utility model relates to a kind of automobile component, is specifically related to protect acoustic cladding under a kind of automotive engine.
Background technology
The driving engine of automobile is usually located on the front frame of vehicle, in the vehicle traveling process, outside if driving engine is exposed to, although make the heat radiation of driving engine obtain good solution, in the process of moving, the foreign material such as the silt on the road, stone can enter in the vehicle frame, work to driving engine causes adverse effect, for example, foreign material enter belt affects engine operation, or foreign material enter driving engine engine life is reduced.And present engine lower guard board dispels the heat for convenient, usually can be not totally-enclosed, so still can cause entering of foreign matter.On the other hand, the operational sound of driving engine can spread out of the external world along with untight backplate, causes noise emission.
The utility model patent that by name " engine protecting ", a notification number are CN 201089433Y discloses a kind of engine protecting, this device comprises a main body and is located at aeration structure on the main body, aeration structure is netted vent window, by in main body vent window being set, solve the heat dissipation problem of automotive engine, but this set can not reduce the noise of driving engine.
The utility model content
In order to overcome the deficiency of present existing product, the purpose of this utility model provides under a kind of driving engine that can protect driving engine not to be subjected to extraneous infringement and can control motor noise and protects acoustic cladding.The utility model is carried out by following scheme:
Protect acoustic cladding under a kind of automotive engine, comprise the arc main body that is positioned at driving engine below, main body comprises three layers of noise reduction layer, sound isolating layer and protective layers from top to bottom, forms cavity between noise reduction layer and the protective layer, sound isolating layer is positioned at cavity, and the noise reduction layer is captiveed joint with protective layer.The arc main body can reduce resistance, reduces vehicle body because of the impact of resistance on the speed of a motor vehicle.Three-decker on the main body not only can stop external foreign matter to the infringement of driving engine, and has reduced the pollution of engine noise.The noise reduction layer reduces the intensity of sound of driving engine, and sound isolating layer deadens sound, and protective layer foreign matter to external world stops, and has protected driving engine to avoid infringement.
As preferred version, described noise reduction layer is trellis work, and the upper surface of noise reduction layer is provided with the sheet projection.Grid can increase the order of reflection of sound, reduces the intensity of sound.The sheet projection not only can reduce the intensity of sound, and can carry out choked flow to the air of ventilation inlet, air is contacted tightr with driving engine, fully reduces the temperature of driving engine.
As preferred version, sound isolating layer adopts Sound-proof material.Sound-proof material can intercept sound by actv..
As preferred version, body shape and driving engine match and complete covering engine bottom.The safety of whole driving engine can effectively be protected in the covering engine bottom.
As preferred version, the main body lower surface is provided with reinforced rib.Reinforced rib can increase the intensity of main body.
As preferred version, the noise reduction layer is connected by buckle with the periphery of protective layer.The noise reduction layer is connected with the protective layer bayonet socket can be so that the installation of sound isolating layer.
Owing to having adopted technique scheme; the protection acoustic cladding is simple in structure under the automotive engine of the present utility model; with low cost; not only can protect driving engine to avoid the injury of extraneous foreign matter; thereby guarantee the normal operation of driving engine; and have sound insulation, sound deadening, can effectively reduce the noise emission that driving engine causes to external world.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure: 1 main body, 2 noise reduction layers, 3 sound isolating layers, 4 protective layers, 5 sheets projection.
The specific embodiment
The utility model is described further with specific embodiment below in conjunction with accompanying drawing.
Protect acoustic cladding under a kind of automotive engine, as shown in Figure 1, the main body 1 that comprises the arc that is positioned at the driving engine below, main body 1 matches with the driving engine shape size and complete covering engine bottom, main body 1 comprises 4 three layers of noise reduction layer 2, sound isolating layer 3 and protective layers from top to bottom, form cavity between noise reduction layer 2 and the protective layer 4, sound isolating layer 3 is positioned at cavity, peripheral fixed by snap connection of noise reduction layer 2 and protective layer 4.Noise reduction layer 2 is trellis work, and the upper surface of noise reduction layer 2 is provided with sheet projection 5.Be filled with Sound-proof material in the sound isolating layer 3.In order to strengthen the intensity of main body 1, be provided with reinforced rib at protective layer 4 lower surfaces of main body.
