Description

Technical Field

[0001] This utility model relates to the field of support structure technology, and in particular to a high-modality compressor support structure. Background Technology

[0002] In some vehicles, due to the extremely close proximity of the compressor and motor and the limited design space, the compressor bracket uses a rigid connection method, meaning the compressor and motor are directly connected via the compressor bracket, without any padding structure on the bracket (see the attached manual). Figure 7 In this hard-connection situation, the first-order modal frequency of the compressor bracket will directly affect the NVH performance of the compressor system. For example, the existing bracket material currently under study is made of high-pressure cast aluminum, and its first-order modal frequency is 218.967Hz.

[0003] The first-order modal frequency is the lowest vibration frequency of the support structure. Increasing the first-order modal frequency can enhance the structural stiffness, avoid resonance, and thus improve the stability and service life of the structure. In order to meet the market demand for vehicle vibration isolation and noise reduction, a systematic analysis of the compressor support revealed that a high-modal compressor support is needed to assemble the compressor in order to obtain better NVH performance. Utility Model Content

[0004] This invention provides a high-modal compressor support structure, which can solve the problem of low first-order modal frequency in existing compressor supports.

[0005] A high-modality compressor support structure includes a support body, which includes an inner mounting part, an outer mounting part, and an L-shaped reinforcing part. The outer mounting part is disposed on the outer surface of the inner mounting part, and a mounting hole one and a mounting hole two are provided through the upper end surface of the outer mounting part. The L-shaped reinforcing part is disposed on one side of the outer mounting part and close to the mounting hole one.

[0006] As a further technical solution of this utility model, the end of the L-shaped reinforcing part extends in a direction away from the inner mounting part.

[0007] As a further technical solution of this utility model, the L-shaped reinforcing part is provided with a chamfer one at the end near the first mounting hole, and the L-shaped reinforcing part is provided with a chamfer two at the end near the second mounting hole.

[0008] As a further technical solution of this utility model, the lower surface of the inner mounting part is provided with connecting boss three, connecting boss five and connecting boss six.

[0009] As a further technical solution of this utility model, the upper surface of the inner mounting part is provided with mounting hole three, mounting hole five and mounting hole six, mounting hole three is connected through boss three, mounting hole five is connected through boss five and mounting hole six is ​​connected through boss six.

[0010] As a further technical solution of this utility model, mounting holes three, five and six are all countersunk holes.

[0011] As a further technical solution of this utility model, the upper surface of the inner mounting part is provided with a connecting boss four, and the upper surface of the inner mounting part is provided with a plurality of vertical reinforcing ribs that cooperate with the connecting boss four.

[0012] As a further technical solution of this utility model, the upper end face of the connecting boss four is provided with a mounting hole four, and the upper end face of the peripheral mounting part is provided with a mounting hole seven.

[0013] As a further technical solution of this utility model, the mounting hole one, mounting hole four and mounting hole seven are threaded holes.

[0014] As a further technical solution of this utility model, the upper surface of the inner mounting part is provided with multiple notches.

[0015] The beneficial effects of this utility model are:

[0016] 1. Since the location of mounting hole one is used for the installation connection between the bracket body and the compressor body, and this location is closest to the center of mass of the compressor body, this location is most affected by the vibration of the compressor body. The location of mounting hole two is used for the installation connection between the bracket body and the motor body. The vibration generated by the compressor body is transmitted to the area where mounting hole one is located through the area where mounting hole two is located. The L-shaped reinforcement is provided to improve the modal vibration of the bracket body.

[0017] 2. Only if the end of the L-shaped reinforcing part extends vertically upward (towards the compressor body) can it improve the modality of the support body; otherwise, it will not help the modality of the support body. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0027] Reference Figures 1-7 A high-modality compressor support structure includes a support body 100. The support body 100 includes an inner mounting part 101, an outer mounting part 102, and an L-shaped reinforcing part 103. The outer mounting part 102 is disposed on the outer surface of the inner mounting part 101. The upper end surface of the outer mounting part 102 is provided with a first mounting hole 104 and a second mounting hole 105. The L-shaped reinforcing part 103 is disposed on one side of the outer mounting part 102 and close to the first mounting hole 104.

[0028] The bracket body 100 is a one-piece molded structure, and the material used is high-pressure die-cast aluminum.

[0029] The bracket body 100 is mounted above the motor body, and the compressor body is mounted above the bracket body 100.

[0030] Since the mounting hole 104 is located at the position used for the mounting connection between the bracket body 100 and the compressor body, and this position is closest to the center of mass of the compressor body, this position is most affected by the vibration of the compressor body. The mounting hole 105 is located at the position used for the mounting connection between the bracket body 100 and the motor body. The vibration generated by the compressor body is transmitted to the region where the mounting hole 104 is located. If we want to increase the first-order modal frequency of the bracket body 100, we must strengthen the structure of the region from the mounting hole 104 to the mounting hole 105. Since the compressor body is above the outer mounting part 102 corresponding to the mounting holes 104 and 105, there is not enough space to extend the outer mounting part 102 of the region where the mounting holes 104 and 105 are located upwards. Therefore, we can only provide an L-shaped reinforcing part 103 on the side of the outer mounting part 102 of the region where the mounting holes 104 and 105 are located to improve the modal frequency of the bracket body 100.

[0031] After performing a first-order modal frequency analysis on the support body 100 of this application, the result is 241.69Hz.

[0032] The end of the L-shaped reinforcing part 103 extends in a direction away from the inner mounting part 101.

[0033] The L-shaped reinforcing part 103 can only improve the mode of the support body 100 if the end extends vertically upward (towards the direction close to the compressor body); otherwise, it will not help the mode of the support body 100.

[0034] The L-shaped reinforcing part 103 has a chamfer 200 at one end near the mounting hole 104, and a chamfer 201 at the other end near the mounting hole 105.

[0035] The chamfers 200 and 201 are designed to enhance the modality of the support body 100 and improve the overall strength of the support body 100.

[0036] The lower surface of the inner mounting part 101 is provided with connecting boss three 106, connecting boss five 107 and connecting boss six 108.

[0037] The connecting bosses 106, 107, and 108 are used to facilitate the installation connection between the bracket body 100 and the motor body.

[0038] The upper surface of the inner mounting part 101 is provided with mounting hole 3 109, mounting hole 5 110 and mounting hole 6 111. Mounting hole 3 109 is connected to boss 3 106 through mounting hole 110, boss 5 107 through mounting hole 111 and boss 6 108 through mounting hole 111.

[0039] Mounting holes 2 (105), 3 (109), 5 (110), and 6 (111) are used to connect the motor body. They are connected with M8 bolts, and the motor body has matching M8 threaded holes.

[0040] Mounting holes 3.109, 5.110, and 6.111 are all countersunk holes used to fit and install the motor body.

[0041] The upper surface of the inner mounting part 101 is provided with a connecting boss 4 112, and the upper surface of the inner mounting part 101 is provided with a plurality of vertical reinforcing ribs 113 that cooperate with the connecting boss 4 112. The plurality of vertical reinforcing ribs 113 have different structural dimensions in order to match the bracket body 100.

[0042] The multiple vertical reinforcing ribs 113 are mainly used to strengthen the modality of the support body 100, and secondly, to improve the overall strength of the support body 100.

[0043] A mounting hole 114 is provided through the upper end face of the connecting boss 112, and a mounting hole 115 is provided through the upper end face of the peripheral mounting part 102.

[0044] Mounting holes 104, 114, and 115 are used to connect the compressor body.

[0045] Mounting hole 104, mounting hole 414, and mounting hole 715 are threaded holes, suitable for use with M8 bolts.

[0046] Multiple notches 202 are provided through the upper surface of the inner mounting part 101.

[0047] The multiple slots 202 have different shapes and sizes. The purpose of setting multiple slots 202 is to avoid the compressor body and motor body during installation and use.

[0048] In use, the mounting hole 104 is located at the position used for the installation connection between the bracket body 100 and the compressor body, and this position is closest to the center of mass of the compressor body. Therefore, this position is most affected by the vibration of the compressor body. The mounting hole 105 is located at the position used for the installation connection between the bracket body 100 and the motor body. The vibration generated by the compressor body is transmitted to the area where the mounting hole 104 is located to the area where the mounting hole 105 is located. The L-shaped reinforcing part 103 is provided to improve the modal characteristics of the bracket body 100.

[0049] The above-disclosed embodiments are merely preferred embodiments of the present utility model. However, the embodiments of the present utility model are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
