Description

The present invention relates to a mounting structure for a compressor.

The above compressor is provided with mounting feet. A bolt is inserted into the mounting foot. The bolt is threaded into a component of the vehicle. Thereby, the compressor is attached to a component of the vehicle. In the compressor described in Patent Document 1, vibration transmitted from the compressor to the vehicle component can be damped by providing one or more washers between the vehicle component and the mounting foot.

JP2020-67037A

However, the bolt and the mounting foot are in contact, and the bolt and the component of the vehicle are in contact. Therefore, the vibrations of the compressor are transmitted to the vehicle components via the bolts. Therefore, there is a possibility that the noise of the compressor will be diffused from the vehicle body.

A compressor mounting structure that solves the above problem is a compressor mounting structure for mounting a compressor on a component of a vehicle, which includes a mounting foot provided on the compressor and a mounting foot attached to the component. an outer cylindrical member; and an inner cylindrical member attached to the inside of the outer cylindrical member via an elastic member, a thread groove is provided on the inner circumferential surface of the inner cylindrical member, and a bolt is attached to the mounting leg. The compressor is attached to the component by being inserted into the formed insertion hole and screwed into the thread groove.

According to the above configuration, the compressor is attached to the component of the vehicle by fixing the mounting foot and the inner cylinder member with bolts while the elastic member is sandwiched between the outer cylinder member and the inner cylinder member. . In other words, the compressor can be attached to the vehicle component while the bolts are separated from the vehicle component. The vibration of the compressor transmitted to the bolt is transmitted to the elastic member via the inner cylindrical member and is absorbed by the elastic member. Therefore, vibrations of the compressor are suppressed from being transmitted to the outer cylinder member. This makes it difficult for the vibrations of the compressor to be transmitted to the structural members of the vehicle. Therefore, it is possible to suppress the noise of the compressor from being diffused from the structural members of the vehicle.

In addition, the bolt is screwed into the thread groove of the inner cylinder member. This simplifies the mounting structure of the compressor compared to fixing the mounting foot and the inner cylindrical member by screwing a fixing member such as a nut onto the bolt while the bolt is inserted through the mounting foot and the inner cylindrical member. It can be configured as follows.

In the compressor mounting structure described above, the outer cylinder member has an annular flange portion extending along the component member from an end opposite to the component member, and the flange portion It is preferable that the device has an annular opposing surface facing the component, and that the opposing surface is fixed to the component while being in surface contact with the component.

Vibrations from the compressor may cause the bolts to vibrate in a tilted manner. According to the above configuration, in this case, the bolt is supported by the elastic member together with the inner cylindrical member. When the bolt vibrates in an inclined manner due to vibrations of the compressor, the weight of the compressor is transmitted to the outer cylinder member via the elastic member, but the annular opposing surface is in surface contact with the component. Therefore, the stress acting on the outer cylinder member can be dispersed by the flange portion. Therefore, deformation of the outer cylinder member due to the weight of the compressor can be suppressed.

In the compressor mounting structure described above, the component may be a frame that constitutes a vehicle body.
According to the above configuration, vibrations of the compressor are less likely to be transmitted to the frame of the vehicle body via the bolts. Therefore, the vibrations of the compressor are less likely to be transmitted into the cabin of the vehicle, making it possible to improve the quietness of the cabin.

According to this invention, it is possible to suppress the noise of the compressor from being diffused from the structural members of the vehicle.

<Action of this embodiment>
The operation of this embodiment will be explained.
When the compressor 10 is driven, vibrations generated by the driving of the compression section 30 and the electric motor 40 are transmitted from the mounting foot 60 to the bolt 71. According to this embodiment, the compressor 1 is attached to the frame 101. That is, the compressor 10 can be attached to the frame 101 with the bolts 71 separated from the frame 101. The vibration of the compressor 10 transmitted to the bolt 71 is transmitted to the elastic member 73 via the inner cylinder member 74 and is absorbed by the elastic member 73. Therefore, vibrations of the compressor 10 are suppressed from being transmitted to the outer cylinder member 72. Therefore, vibrations of the compressor 10 are less likely to be transmitted to the frame 101.

In addition, the bolt 71 is screwed into a threaded groove 741d of the inner cylinder member 74. Compared to the case where the mounting foot 60 and the inner cylindrical member 74 are fixed by screwing a fixing member such as a nut onto the bolt 71 with the bolt 71 inserted through the mounting foot 60 and the inner cylindrical member 74, the compression is reduced. The mounting structure 70 of the machine 10 can have a simple configuration.

<Effects of this embodiment>
The effects of this embodiment will be explained.
(1) The attachment structure 70 allows the compressor 10 to be attached to the frame 101 without the bolts 71 coming into contact with the frame 101, and the elastic member 73 makes it difficult for vibrations of the compressor 10 to be transmitted to the frame 101. Therefore, the noise of the compressor 10 can be suppressed from being diffused from the frame 101.

(2) The outer cylinder member 72 has an annular flange portion 723 extending from the first end portion 721a. The flange portion 723 has an annular opposing surface 723a. The flange portion 723 is fixed to the frame 101 with the opposing surface 723a in contact with the mounting plane 101a of the frame 101. Vibrations of the compressor 10 may cause the bolts 71 to vibrate so as to tilt. According to this embodiment, in this case, the bolt 71 is supported by the elastic member 73 together with the inner cylinder member 74. When the bolts 71 vibrate in an inclined manner due to the vibrations of the compressor 10, the weight of the compressor 10 is transmitted to the outer cylinder member 72 via the elastic member 73, but the annular opposing surface 723a comes into surface contact with the frame 101. There is. Therefore, the stress acting on the outer cylinder member 72 can be dispersed by the flange portion 723. Therefore, deformation of the outer cylinder member 72 due to the weight of the compressor 10 can be suppressed.

(3) The mounting structure 70 is fixed to the frame 101. According to this embodiment, vibrations of the compressor 10 are less likely to be transmitted to the frame 101 of the vehicle body via the bolts 71. Therefore, the vibrations of the compressor 10 are less likely to be transmitted into the cabin of the vehicle, making it possible to improve the quietness of the cabin.

(4) When the vibrations of the compressor 10 are transmitted to the bolts 71, the vibrations are transmitted to the inner cylinder member 74. However, the vibration transmitted to the inner cylinder member 74 is absorbed by the elastic member 73. Therefore, compared to the case where the bolt 71 is fixed to the frame 101, deformation of the bolt 71 starting from the point where the bolt 71 is fixed to the inner cylinder member 74 is suppressed. Therefore, deformation of the bolts 71 due to vibrations of the compressor 10 is suppressed.

Furthermore, even if the compressor 10 attempts to move in the direction in which the mounting legs 60, bolts 71, and inner cylinder member 74 are removed from the outer cylinder member 72 due to breakage of the elastic member 73, etc., the second extending portion 742 At the same time, the elastic member 73 contacts the first extending portion 722 . Since the outer cylindrical member 72 is attached to the frame 101, the load from the elastic member 73 can be supported by the outer cylindrical member 72 via the first extension portion 722. Therefore, the bolt 71 and the inner cylinder member 74 can be prevented from coming off from the outer cylinder member 72. Therefore, the compressor 10 is prevented from coming off from the outer cylinder member 72. That is, the compressor 10 is prevented from moving away from the mounting position of the frame 101. Therefore, while suppressing deformation of the bolts 71, it is possible to prevent the compressor 10 from moving away from the mounting position of the frame 101.

(5) The first extending portion 722 and the second extending portion 742 are arranged to overlap in the axial direction of the inner cylinder member 74. Therefore, the area of the elastic member 73 sandwiched between the first extending portion 722 and the second extending portion 742 becomes wider. Therefore, even if the compressor 10 attempts to move in the direction in which the mounting legs 60, bolts 71, and inner cylinder member 74 are removed from the outer cylinder member 72, it is possible to further suppress the compressor 10 from leaving the mounting position of the frame 101.

(6) According to the present embodiment, the vibrations of the compressor 10 are not easily transmitted to the frame 101, which improves the quietness of the vehicle interior, and the vibrations of the compressor 10 are also prevented from being transmitted to the handlebars and seats in the vehicle interior. It can be suppressed. Therefore, it is possible to prevent the driver from feeling uncomfortable in the operation.

(7) As a structure that makes it difficult for the vibrations of the compressor 10 to be transmitted to the bolts 71 to be transmitted to the frame 101, the bolts 71 are fixed to the outer cylinder member 72, and there is an elastic force between the inner surface of the insertion hole 61 of the mounting leg 60 and the bolt 71. It is also conceivable to interpose a member 73. However, in order to insert it into the insertion hole 61, it is necessary to process the elastic member 73 into a small size.

In this regard, in this embodiment, the elastic member 73 is sandwiched between the outer cylinder member 72 and the inner cylinder member 74. Therefore, compared to a configuration in which the elastic member 73 is inserted into the insertion hole 61 of the mounting leg 60, a sufficient size of the elastic member 73 can be ensured. This improves the workability of the elastic member 73, such as making it easier to form the insertion hole 73a in the elastic member 73. Therefore, compared to a configuration in which the elastic member 73 is inserted into the insertion hole 61 of the mounting leg 60, the mounting structure 70 can be realized more simply.
