Description
Technical field
The utility model relates to automobile technical field more particularly to a kind of automotive hoods of damping noise reduction.
Background technique
Automobile engine is the machine that the energy of a certain form is converted to mechanical energy, and function is by liquid or gas
Chemical energy mechanical energy and external output power, automobile are converted by expansion by being converted into thermal energy after burning, then thermal energy
Power come from engine, different according to fuel used, common engine can be divided into petrol engine and diesel engine
Two kinds.Engine is the heart of automobile, provides power for the walking of automobile, however the protective capability of existing automotive hood
Poor, the mainly ability of automotive hood damping and reduction noise is poor, causes in driving conditions, the noise of engine
It is diffused into cockpit, influences to drive indoor environment.
Summary of the invention
The utility model aims to solve the problem that the deficiencies in the prior art, and provides a kind of automotive hood of damping noise reduction, can
Reduce influence of the noise of engine in driving conditions for driving indoor environment.
In order to achieve the above object, the utility model adopts the following technical solutions:
A kind of automotive hood of damping noise reduction, including hood shell, the hood shell inside are equipped with
Buffer layer and noise reduction layer, the setting of noise reduction layer is at middle part, and buffer layer setting is in noise reduction layer periphery, and the buffer layer is from outside to inside successively
Comprising the first shock absorption strip, damping block and damping spring, the second shock absorption strip, first shock absorption strip is mounted on hood shell
On, damping block and damping spring are evenly arranged on the first shock absorption strip, and the damping block and damping spring are separately arranged, the second damping
Item is fixedly mounted on the other side of damping block and damping spring, and the central part of the buffer layer is equipped with lock, the noise reduction layer
Ecto-entad successively includes thermal insulation layer, noise reduction layer, puigging, and the noise reduction layer includes muffling hole plate layer and air layer, wherein
Air layer is close to thermal insulation layer.
The thermal insulation layer is glass fibre heat insulation foam.
The muffling hole plate is zinc-plated punched-plate.
The puigging is sound insulation cotton layer.
The beneficial effects of the utility model are: the utility model is provided with noise reduction layer and puigging to hair in hood
The noise that motivation generates carries out decrease absorption, provides relatively comfortable environment by bus, reduces driving conditions by setting buffer layer
In vibration.
Detailed description of the invention

It is described in detail below with reference to the embodiments of the present invention referring to attached drawing.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figure 1 to Figure 3, a kind of automotive hood of damping noise reduction, including hood shell 1, it is described to start
Buffer layer and noise reduction layer are equipped on the inside of hood shell 1, for the setting of noise reduction layer at middle part, buffer layer setting is described in noise reduction layer periphery
Buffer layer successively includes the first shock absorption strip 2, damping block 3 and damping spring 4, the second shock absorption strip 9, first damping from outside to inside
Item 2 is mounted on hood shell 1, and damping block 3 and damping spring 4 are evenly arranged on the first shock absorption strip 2,3 He of damping block
Damping spring 4 is separately arranged, and the second shock absorption strip 9 is fixedly mounted on the other side of damping block 3 and damping spring 4, the damping
The central part of layer is equipped with lock 5, and the noise reduction layer ecto-entad successively includes thermal insulation layer 8, noise reduction layer 7, puigging 6, institute
Stating noise reduction layer 7 includes muffling hole plate layer and air layer, and wherein air layer is close to thermal insulation layer 8.
The thermal insulation layer 8 is glass fibre heat insulation foam.
The muffling hole plate is zinc-plated punched-plate.
The puigging 6 is sound insulation cotton layer.
The noise that the utility model generates engine provided with noise reduction layer 7 and puigging 6 in hood subtracts
Weak absorbing provides relatively comfortable environment by bus, the vibration in driving conditions is reduced by setting buffer layer.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, if the method concept of the utility model and the various improvement of technical solution progress are used, or without
Improvement directly applies to other occasions, both is within the protection scope of the present invention.
