Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soundproof box structure for an on-vehicle compressor for air conditioning of a vehicle.

[0002]

2. Description of the Related Art In recent years, there is an air conditioner for an automobile which is equipped with an electric compressor and which controls the rotation speed of a storage battery and which does not depend on the engine speed of the vehicle.

Conventionally, in the case of an electric compressor mounted on a leisure car, for example, a support for a vehicle of a compressor of an air conditioner for an automobile of this type has legs at the bottom of the compressor and the compressor itself. In order to prevent the vibration of the vehicle from being transmitted to the vehicle, an elastic material such as anti-vibration rubber is interposed, and it is supported and fixed to the vehicle by bolts or the like. Hereinafter, description will be given with reference to the drawings.

FIG. 4 shows a conventional compressor support structure. In the figure, the leg 2 is fixed to the bottom portion of the compressor body 1 by welding, the leg 2 has an insertion hole for the vibration isolating rubber 3, and the leg 2 is welded to the vehicle sheet metal 4 through the vibration isolating rubber 3. It is supported and fixed to the vehicle sheet metal 4 by the stud bolts 5 and the flange nuts 6 which are formed.

In the conventional example shown in FIG. 4, when the vehicle sheet metal 4 receives external vibrations such as when a vehicle is traveling, the upper part of the compressor body 1 is greatly vibrated because the upper part of the compressor body 1 is vibrated greatly. There is a problem with durability, and since high- and low-pressure pipes are connected to the compressor body, propagation vibration occurs. Moreover, since the compressor body is exposed, noise is loud. Also,
Condensation water on the low pressure side is easily scattered. Also, when a soundproof box is configured, it is difficult to fix it to the vehicle.

Further, as a conventional example, in which a compressor of a vehicle air conditioner is separated into a compressor chamber to reduce noise and propagation vibration, Japanese Utility Model Laid-Open No. 64-49411 discloses a compressor. The method of supporting the machine body is not described.

[0007]

[Problems to be Solved by the Invention]

 (1) Large vibration of the upper part of the compressor body due to external vibration.

(2) Vibration durability of the compressor and soundproof box. (3) Condensation water treatment.

(4) Noise. The above has been a problem in supporting a compressor of an automobile air conditioner in a soundproof box.

The present invention is intended to solve the above problems, and it is an object of the present invention to reduce vibration of the upper part of a compressor body, to securely fix a soundproof box to a vehicle in consideration of vibration durability, drain water treatment, and noise reduction. It is what

[0011]

[Means for Solving the Problems]

(Claim 1) In a compressor body and a compressor soundproof box having the compressor body built-in, a support metal fitting arranged on an upper part of the compressor body and the support metal fitting arranged on an inner surface of the compressor soundproof box. The receiving member is composed of an elastic material.

(Claim 2) In the vibration-proof rubber for fixing the legs of the compressor main body to the bottom plate of the soundproof box, the structure has a bolt portion penetrating the bottom plate of the soundproof box.

(Claim 3) The bottom plate of the soundproof box is inclined, and the bottom plate is provided with a drain hole.

[0014]

[Action]

(Claims 1, 2, 3) According to the present invention, the compressor main body is housed in a compressor soundproof box, and the upper part of the compressor main body is fixed to the compressor box with an elastic member interposed therebetween. It was possible to reduce noise. In addition, bolting out from the bottom of the soundproof box makes it easier to fix to the vehicle, and the compressor and vehicle are fixed with the same anti-vibration rubber, which improves vibration durability. In addition, since the bottom plate is provided with a drain hole, the treatment of condensed water is facilitated and the safety is improved.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of support in a soundproof box of a compressor for an automobile according to the present invention. In the compressor body 1, first, the legs 2 of the compressor body 1 are composed of the components of the vibration proof rubber 7, the flange nut 6 and the nut 8 in the compressor soundproof box 9 having the soundproof material 13 attached to the inner wall. It is supported and fixed via.
A support fitting 11 fixed on the upper circumference of the body shell of the compressor body 1 and a receiving member 12 installed on the inner surface of the compressor soundproof box 9 for receiving the support fitting 11 are provided. The receiving member 12 supports and fixes the upper portion of the compressor body 1 inside the compressor soundproof box 9 via an elastic material 10. The soundproof box bottom plate 14 is provided with an inclination so that the condensed water is discharged from the drain hole 15 at the center.

By supporting and fixing the upper part and the lower part of the compressor body 1 as described above, large vibration of the upper part of the compressor body 1 due to external vibration such as running is absorbed by the elastic material 10, and the compressor is compressed. It is possible to improve the durability of the main body and reduce the propagation vibration to the high and low pressure piping connected to the compressor main body 1.

Further, since the anti-vibration rubber 7 having the bolts adhered to both sides is used, the compressor body 1 can be directly fixed to the vehicle side via the soundproof box bottom plate 14. Therefore, mounting workability and vibration durability are improved.

Further, by housing the compressor body 1 in the compressor soundproof box 9, it is possible to improve the deterioration of the heating capacity due to the running wind cooling the compressor body 1 when the heat pump is heated.

The compressor body 1 or the compressor soundproof box 9
Since the soundproofing material 13 is attached to, the noise of the compressor body 1 is reduced and the heat pump heating capacity is further reduced.

Further, since the drain hole 15 is provided, the condensed water does not scatter around and is dropped from the bottom 14 of the soundproof box to the lower part of the vehicle. Therefore, it is possible to prevent electric leakage due to water splashing and improve safety.
