Abstract

The present invention relates to a blow motor sound insulation of an automobile equipped with a noise prevention and dustproof means to prevent the driving sound of the blow motor and to block the vibration sound.

The conventional blow motor 12 is fastened to the support plate 40 of the unit wall by the mounting screw 42 as shown in FIG. 3, and air is blown into the room through the blow wheel 44.

However, the conventional method of fastening the blow motor 12 as shown in FIG. 3 is that the blow motor 12 itself is exposed to the room, and therefore, the driving sound of the motor is transmitted to the vehicle, thereby countering the development of an improved automobile that pursues low noise. In addition, this may increase the dissatisfaction of the user (operator) to reduce the reliability of the producer.

In addition, since the blow motor 12 rotates at a high speed, vibration is generated according to a long time of use, and this vibration generates a vibration sound that is different from the above-mentioned driving sound, thereby causing a consumer complaint.

Therefore, in the present invention, a rubber band is formed between the case and the blow motor to surround the part exposed to the inside of the blow motor with the case so that the driving sound is not heard and the vibration is also prevented.

In addition, since the motor covered with the case may be overheated, one side of the case is opened to have a heat dissipation function.

The present invention for this purpose in the blow motor 12 is fastened with a mounting screw 42 to the support plate 40 as shown in Figure 3, extending the support plate 40 to surround the case 44 surrounding the blow motor 12 Forming a noise blocking material 46 between the case 44 and the blow motor 12, and forming a straight through hole 48 between the case 44 and the noise blocking material 46. The dustproof ground rubber 50 is formed between the 46 and the blow motor 12.

The present invention relates to a blow motor sound insulation of an automobile, and more particularly, to a blow motor sound insulation of an automobile provided with noise prevention and dustproof means for preventing the driving sound of the blow motor and blocking the vibration sound.

The air circulation principle adopted to comfortably supply the indoor air of the vehicle and to protect the safety and health of the occupants, as shown in FIG. 1, the external air introduced through the cow grip 10 is blown motor ( Passed through the bet inlet 14 of 12) to the evaporator 16, the heater core 18 is installed to supply hot air, the two doors 20, 22 open and close at the driver's option Hot air and cold air are mixed and supplied properly. Therefore, air selected and mixed at an appropriate temperature is supplied to the side ventilator 26 and the defrost 28 through the doors 20 and 22 according to the mode switch operation selected by the driver, and is blown into the vehicle interior.

The configuration of a so-called auto air conditioner of a vehicle which achieves this principle is as shown in FIG. 2, and the reference numeral 13, which is not described here, is an air hose, 30 is an upper case, 32 is a lower case, and 34 is left. Case 36 represents the right case and 38 represents the intake door.

Meanwhile, in connection with the present invention, the conventional blow motor 12 is fastened to the support plate 40 of the unit wall with a mounting screw 42, as shown in FIG. 3, and air is blown through the blow wheel. It is made of a structure that is blown indoors.

However, the conventional fastening method of the blow motor 12 is reversed to the development of an improved automobile that pursues low noise by transmitting the driving sound of the motor because the blow motor 12 itself is exposed to the interior. This increases the dissatisfaction of the user (operator) and may also cause a decrease in the reliability of the producer.

In addition, since the conventional blow motor 12 rotates at a high speed, vibration is generated according to a long time use, and such vibration generates vibration noise that is different from the above-mentioned driving sound, causing a customer complaint. This has been.

An object of the present invention is to solve the conventional problems as described above, by wrapping the part exposed to the interior of the blow motor in the case so that the driving sound is not heard, and the vibration between the case and the blow motor to prevent vibration It is to provide a blow motor sound insulation of the automobile that formed the stage.

In this case, the motor covered with the case may be overheated, so that one side of the case is opened to have a heat dissipation function.

To this end, the blow motor case is formed by extending the support plate to cover the blow motor, or by providing a separate case and fastening and assembling it on the support plate using a screw. The point is the same as before. Accordingly, the present invention is very low noise and vibration even during the operation of the blow motor, the quiet car is provided with an effect that can contribute to the product preference to the satisfaction of the consumer.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the technical idea of the present invention. Shall be.

The configuration of the blow motor soundproof opening according to the embodiment of the present invention, in the blow motor 12 is fastened to the support plate 40 with a mounting screw 42, to extend the support plate 40 to surround the blow motor 12 A case 44 is formed, and a noise blocking material 46 is embedded between the case 44 and the blow motor 12, and a straight through hole 48 is provided in the case 44 and the noise blocking material 46. And a dustproof ground rubber 50 is formed between the noise blocking material 46 and the blow motor 12.

4 is a view showing the configuration of the present invention is assembled, the blow motor 12 is no change in appearance compared to the conventional, but the blow motor 12 is the case 44 extending the support plate 40 ) Is fastened to the screw 52, and the noise blocking material 40 and the anti-vibration ground rubber 50 are installed into the case 44.

Here, the through-hole 48 is formed in the air conditioner use mode to prevent the leakage of cold and in the heater use mode is upward to facilitate the dissipation of the heat of the blow motor 12, dust-proof ground rubber 50 is blow motor 12 Since it is installed in order to prevent the shaking (vibration) of the) as shown in Figure 5, the support portion is arranged in the saga point in the east, west, north and south directions in a plan view, or may be formed at equal intervals in the form of a triangular point or more. .

On the other hand, the noise blocking material 46 is a foam seal (form seal) on which the adhesive is applied, the noise blocking effect is very large, and is not separated after adhesion.

According to the above configuration, the case 44 integrally formed with the support plate 40 is assembled with the blow motor 12 fixed to the support plate 40 by a screw 52 while the noise blocking material 46 is built therein. Between the blocking material 46 and the blow motor 12 is installed as the dustproof rubber 50 is fitted, the noise blocking material 46 and the blower motor 12 are mutually except the portion that the dustproof rubber 50 is in contact with each other. It stays floating without being in contact.

Therefore, the space around the blow motor 12 can be blown in and out through the through hole 48.

The blow motor 12 installed on the support plate 40 is fastened to the blow wall with a screw so that the blow motor 12 is installed at the same position as in the prior art and there is no change of other parts.

According to the present invention having the configuration as described above, the noise blocking effect is large, the quietness of the interior of the vehicle is increased, the vibration of the motor is suppressed and the vibration sound is also blocked to help the driver's pleasant safety operation, thus eliminating consumer complaints. There is an effect that can improve the reliability for the producer.
