no. 1 approach

[0107] figure 1 , figure 2 , Figure 3A , Figure 3B , Figure 3C , Figure 4 A first embodiment of a vibration isolator for a compressor for an in-vehicle air conditioner is shown. The anti-vibration device of the present embodiment performs anti-vibration for suppressing the transmission of vibration generated from the compressor 10 for an in-vehicle air conditioner to the vehicle body 20 .

[0108] Hereinafter, in order to simplify the description, the compressor 10 for an in-vehicle air conditioner is simply referred to as the compressor 10 . As the compressor 10 of the present embodiment, an electric compressor in which a compression mechanism is driven by a built-in electric motor is used.

[0109] like figure 1 , figure 2 As shown, the anti-vibration device of the present embodiment includes one compressor 10 and four elastic members 30a, 30b, 30c, and 30d. Hereinafter, the four elastic members 30a, 30b, 30c, and 30d are simply referred to as elastic members ...

no. 2 approach

[0245] In the above-described first embodiment, an example in which the compressor 10 is arranged on the upper side of the vehicle body 20 has been described, and refer to Figure 22 , Figure 23 The second embodiment of the present invention in which the compressor 10 is instead arranged on the lower side of the vehicle body 20 will be described.

[0246] In the present embodiment and the above-described first embodiment, only the arrangement relationship between the vehicle body 20 and the compressor 10 is different, and the other structures are substantially the same.

[0247] In this embodiment, the arrangement relationship of the end faces 31a, 31b, 31c, 31d of the elastic members 30a, 30b, 30c, 30d, the reference points A, B, C, D, the point P, and the point Q are as follows Figure 24 , Figure 25 shown.

[0248] In the present embodiment, the elastic member 30a is supported by the leg portion 11a of the compressor 10 via the attachment member 13a. The elastic membe...

no. 3 approach

[0258] In the third embodiment, refer to Figure 26 , Figure 27 An example in which the hammer portion 14 is provided in the compressor 10 of the first embodiment described above will be described.

[0259] The compressor 10 in this embodiment is the same as the compressor 10 in the above-described first embodiment except for the hammer portion 14, and therefore, the description of the structure other than the hammer portion 14 is omitted. exist Figure 26 , Figure 27 in, with figure 1 , figure 2 The same symbols denote the same components, and their descriptions are omitted.

[0260] The weight portion 14 is arranged on the lower side in the vertical direction in the compressor 10 . The hammer portion 14 serves to lower the position G of the center of gravity of the compressor 10 as compared with the compressor 10 in the above-described first embodiment.

[0261] Here, when it is higher than the center of gravity position G of the compressor 10 (refer to Figure 2...

Abstract

This vibration isolating device for isolating vibrations by suppressing transmission of vibrations generated by a vibration generating source (10) to a vibration transmitted portion (20) is provided with at least one resilient member (30a, 30b, 30c, 30d), wherein: at least one support member (40a, 40b, 40c, 40d) supporting the vibration generating source by way of the at least one resilient member is disposed on the vibration transmitted portion; the at least one resilient member is disposed between the vibration generating source and the at least one support member, and undergoes elastic deformation to suppress transmission, from the at least one support member to the vibration transmitted portion, of vibrations from the vibration generating source; and the vibration generating source and the at least one resilient member are set in such a way that when the vibration generating source vibrates, a resonant frequency in a plurality of vibration modes generated by the vibration generating source is caused to coincide with one prescribed frequency.

Description

[0001] Cross-reference to related applications [0002] The present application is based on Japanese Patent Application No. 2019-21775 filed on February 8, 2019 and Japanese Patent Application No. 2019-70842 filed on April 2, 2019, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an anti-vibration device. Background technique [0004] Conventionally, a technology has been proposed in which, in a vehicle anti-vibration device, transmission of vibration generated by torque of the engine to the vehicle body is suppressed by an engine mount arranged between the engine and the vehicle body (for example, refer to Patent Document 1). 1). Specifically, vibration in the vehicle width direction (ie, the left-right direction) and vibration in the vertical direction caused by the engine torque are problematic. Therefore, it is necessary to reduce the rigidity in the vehicle width direction and the rigidity in the ver...
