Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of automobile rear venting device.
Background technology
Automobile, in order to regulate compartment wind tool air pressure, improve air in a car compartment, is designed with drafting apparatus at automobile rear usually.This device mainly comprises an air flue, and the front vent design of this air flue is in interior, and the rear vents of this air flue designs in vehicle side rear portion for being connected with car outer air.When compartment internal gas pressure increases, in compartment, gas can push blade open, makes gas in compartment discharge compartment, and then regulates the air pressure in compartment; When compartment inside and outside air pressure balance, the blade interlayer in rear vents can close rear vents, prevents dust from entering compartment.
China patent CN 202782584U discloses a kind of automobile rear vents structure of twi-tier blade structure, it comprises the wind frame being located at automobile rear vents, wind frame has the inner port be connected with automobile rear vents and the external port be communicated with outside car, the direction extended from the inner port of wind frame toward external port in wind frame is provided with the first blade interlayer and the second blade interlayer, first blade interlayer and the second blade interlayer are provided with some blades, and the upper end of blade is connected with wind frame rotationally.The good dustproof effect of this structure, and effectively can reduce noise into the car.
But, blade one end in above-mentioned automobile rear vents and wind frame hinged, the other end is only resisted against on wind frame, and automobile easily jolts in the process of moving and shakes, the above-mentioned blade other end due to be only resisted against on wind frame and between wind frame without annexation, blade is easy to open because of vibrations, and making an uproar and easily enter in compartment from rear vents in extraneous Feng Zaohe road, affects the ride comfort of passenger.
Summary of the invention
The utility model is the problems referred to above existed for existing technology, a kind of automobile rear venting device is provided, technical problem to be solved in the utility model is: how to make the blade in automobile rear venting device can not open because of vibrations, thus improve the anti-acoustic capability of this automobile rear venting device.
The purpose of this utility model realizes by following technical proposal:
A kind of automobile rear venting device, described rear venting device comprises framework, described framework offers the opening that several air feed flow through, it is characterized in that, described rear venting device also comprises several for hiding the blade of described opening, the upper end thereof of described blade is in framework, and the lower end of described blade is connected with described framework by magnetic.
This rear venting device is usually fixed on the gusset of automobile and is connected with the air outside compartment, and by the contact air in a breather pipe and compartment, when compartment internal gas pressure increases, in compartment, gas can push blade open, make gas in compartment discharge compartment, and then regulate the air pressure in compartment; When compartment inside and outside air pressure balance, the blade on rear venting device can close opening, avoids road to make an uproar and wind is made an uproar and entered compartment; Because the blade lower end in this device is connected with framework by magnetic, when automobile jolts or shake, blade lower end is not easily opened because of vibrations, thus is made an uproar in road and wind is made an uproar and not easily entered compartment, improves the anti-acoustic capability of this device.
In above-mentioned a kind of automobile rear venting device, as a kind of scheme, described blade adopts magnetic rubber to make, and the edge of described opening is fixed with several iron blocks.Magnetic rubber is the neoprene mixing magnetic metallic powder, blade adopt magnetic rubber make, both ensure that blade can with the adhesive of iron block phase.
In above-mentioned a kind of automobile rear venting device, alternatively, the lower end of described blade is fixed with several magnet, and the edge of described opening is fixed with iron plate that can be attracting with described magnet.Blade can, by the magnet on it and the iron plate phase adhesive at edge of opening place, make blade not easily open because of vibrations.
In above-mentioned a kind of automobile rear venting device, the lower end of described blade is fixed with several magnet, and described framework adopts iron to make.Blade is by magnet and the adhesive of iron blade phase, and blade adopts iron to make, and do not need separately to increase iron plate or iron block, and the intensity of self is higher.
In above-mentioned a kind of automobile rear venting device, be provided with horizontal grizzly bar and longitudinal grizzly bar in described opening, described horizontal grizzly bar is mutually vertical with longitudinal grizzly bar, and the two ends of described horizontal grizzly bar and the two ends of longitudinal grizzly bar are all fixed in described framework.Be designed with horizontal grizzly bar and longitudinal grizzly bar, the bulk strength of framework can be improved.
Compared with prior art, the utility model has the following advantages:
1, the blade lower end in this device is connected with framework by magnetic, and when automobile jolts or shake, blade lower end is not easily opened because of vibrations, thus is made an uproar in road and wind is made an uproar and not easily entered compartment, improves the anti-acoustic capability of this device.
Accompanying drawing explanation
Fig. 1 is the cutaway view of this rear venting device in embodiment.
Fig. 2 is the block diagram of this rear venting device in embodiment.
In figure, 1, framework; 2, opening; 3, horizontal grizzly bar; 4, longitudinal grizzly bar; 5, blade; 6, iron block.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1 and Figure 2, this automobile rear venting device is fixed on vehicle side, comprise framework 1, framework 1 offers the opening 2 that several air feed flow through, horizontal grizzly bar 3 and longitudinal grizzly bar 4 is provided with in opening 2, horizontal grizzly bar 3 is mutually vertical with longitudinal grizzly bar 4, and the two ends of horizontal grizzly bar 3 and the two ends of longitudinal grizzly bar 4 are all fixed in framework 1.Specifically, four longitudinal grizzly bars 4 and a horizontal grizzly bar 3 is provided with in an opening 2.
As shown in Figure 1 and Figure 2, rear venting device also comprises several for hiding the blade 5 of opening 2, and the upper end thereof of blade 5 is in framework 1, and the lower end of blade 5 is connected with described framework 1 by magnetic.In the present embodiment, blade 5 adopts magnetic rubber to make, and the edge of opening 2 is fixed with several iron blocks 6.Magnetic rubber is the neoprene mixing magnetic metallic powder, and blade 5 adopts magnetic rubber to make, both ensure that blade 5 can with the adhesive of iron block 6 phase, simultaneously because blade 5 has certain elasticity, good damping effect can be played when blade 5 closes.Alternatively, the lower end of blade 5 is fixed with several magnet, and the edge of opening 2 is fixed with iron plate that can be attracting with magnet.Or the lower end of blade 5 is fixed with several magnet, blade 5 adopts iron to make.Blade 5 is by magnet and the adhesive of iron blade 5 phase, and framework 1 adopts iron to make, and does not need separately to increase iron plate or iron block 6, and the intensity of self is higher.
The principle of work of this device is as follows: when compartment internal gas pressure increases, in compartment, gas can push blade 5 open, makes gas in compartment discharge compartment, and then regulates the air pressure in compartment; When compartment inside and outside air pressure balance, the blade 5 on rear venting device can close opening 2, avoids road to make an uproar and wind is made an uproar and entered compartment; Blade 5 in this device, by the magnetic of self and the iron block 6 phase adhesive in framework 1, is avoided opening because of vibrations.
