Abstract
The utility model discloses a noise reduction device for an air compressor of a passenger car. The noise reduction device is a box body; the box body wraps a motor and an air pump of the air compressor; an alternating-current frequency conversion starter of the air compressor is arranged on the outer side of the box body; and a fan is arranged on one side of the box body, and an air outlet is formed on the other side of the box body, which is opposite to the fan. According to the noise reduction device, dispersed structures of the air compressor are integrated in the closed box body with a sound attenuation function, and a cooling system of the fan is arranged additionally to discharge heat in closed space.
Description
Technical field
The utility model relates to a kind of traffic tool annex, relates in particular to a kind of passenger vehicle air compressor denoising device.
Background technique
The size of automobile noise is to weigh the important indicator of automobile oeverall quality, and it often can reflect the height of automobile overall technology performance.In short; The give it the gun generation of pass-by noise of automobile is a result who comprises the concentrated expression of various heterogeneity noises, its during mainly by engine combustion working copy bulk noise, vent systems noise, gas handling system noise, cooling fan noise, engine operation body vibration noise, transmission system noise, tire running noise, vehicle body disturb noise that airborne noise, automotive body vibration produce etc.
The conventional air compressor that adopts of present pure electric car is to disperse exposed the installation, causes each parts of after engine room very messy and take up room greatlyyer, and car load looks not only dangerous but also lack of standardization attractive in appearance.And turn round automatically work and produce unpleasant noise of inflating pump when vehicle air pressure is lower than specified value, comfort of passenger in the influence of noise car.
The model utility content
Goal of the invention: the purpose of the utility model provides a kind of passenger vehicle air compressor denoising device, is used for the noise that the secluding air compressor sends.
Technological scheme: for realizing above-mentioned purpose; A kind of passenger vehicle air compressor denoising device of the utility model; This device is a casing, the motor and the air pump of said casing parcel air compressor, and the AC frequency conversion starter of said air compressor is installed in the casing outside; Said casing one side is installed blower fan, and said casing has exhaust port at the opposite side of relative blower fan.
Motor, the air pump of the air compressor that a kind of passenger vehicle compressor noise-reduction device of the utility model will disperse originally are integrated in the enclosed space, because the noise that motor and air pump take place is maximum; And the noise of AC converter and blower fan is very little, places casing not influence quiet effect outward.
The gentle pump-foot of respective motor place is provided with base support in the said casing, and said support is positioned at casing insulator is installed outward.
Maintenance of the utility model and use for ease, but a side of said casing is the movable access door of folding.Said movable access door is provided with the viewing window of observable air pump liquid level.
In order to realize the quiet design of the utility model, said interior is provided with puigging, the puigging that said puigging is processed for the sawtooth Sound-proof material.
Beneficial effect: a kind of passenger vehicle air compressor denoising device of the utility model; Be installed in the closed box with silencing function each structure of air compressor of originally disperseing is integrated, the cooling system that has a blower fan through increase is in addition realized the heat discharge of enclosed space is gone out.The utility model is simple in structure, and the Security of whole system is improved, and realizes the quiet design of air compressor.
Description of drawings
Fig. 1 is the generalized section of the utility model;
Fig. 2 is the structural representation of the utility model;
Fig. 3 is the schematic representation of the utility model puigging.
Embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
With reference to figure 1, Fig. 2, shown in Figure 3; The casing 1 that a kind of passenger vehicle air compressor denoising device of the utility model is processed for the 1.2mm steel plate; This casing length is 600mm, and width is 490mm, highly is 460mm; At the positive movable access door 2 that a door assembly with hinge and glass in right hand and left mechanism is installed of casing, movable access door 2 is provided with the viewing window 3 of observable air pump oil level.Accommodate air pump 4 and motor 5 in the casing 1, in casing 1 left upper portion AC frequency conversion starter 6 is installed, bottom, casing 1 left side is equipped with blower fan 7, and blower fan 7 is sent into cold wind in casing 1, discharges hot blast from the exhaust port 8 that casing 1 opposite side has.The place of corresponding air pump 4 and motor 5 is provided with support below the casing 1, and support extends outside casing 1 and is connected to ground through insulator 9.
Casing 1 internal surface is provided with puigging 10, the puigging that puigging is processed for the sawtooth Sound-proof material.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
