Description

Technical Field

[0001] This utility model relates to the field of automotive air supply unit technology, specifically to a vibration damping installation structure for an automotive air supply unit. Background Technology

[0002] With the rapid development of new energy vehicles, the installation requirements for air supply units inside automobiles are becoming increasingly stringent. The integration level of air supply units is also increasing, requiring specific installation structures to be used in automobiles. In order to reduce the vibration of the air supply unit as the vehicle moves, vibration damping structures are needed for its installation. However, existing vibration damping structures only use conventional vibration damping bushings for vibration damping connections. Since air supply units mostly use a bidirectional plunger structure to generate high-pressure gas, they themselves will also generate relatively large vibrations during operation. Existing vibration damping bushings can no longer meet the vibration damping installation requirements of air supply units. Utility Model Content

[0003] This invention provides a vibration damping mounting structure for an automotive air supply unit, which can solve the problem that existing vibration damping structures cannot meet the vibrations generated during the operation of the air supply unit and the driving of the vehicle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vibration damping mounting structure for an automotive air supply unit, comprising a mounting bracket, a first vibration damping pad mounted on one side of the mounting bracket, a second vibration damping pad disposed on the other side of the mounting bracket, a first bracket pad disposed on the outer side of the first vibration damping pad, a second bracket pad connected to the outer side of the second vibration damping pad, a plurality of bracket springs disposed between the first vibration damping pad and the first bracket pad, and a plurality of springs sequentially passing through the first bracket pad, the first vibration damping pad, the mounting bracket, and the second vibration damping pad mounted on the mounting bracket. The mounting bracket has bracket bolts for the first and second bracket pads. Several vibration damping bushing assemblies are provided at the edge of the mounting bracket. By setting the first bracket pad, the first vibration damping pad, the bracket spring, the second vibration damping pad, and the second bracket pad, the air supply unit can be supported for vibration damping. The first and second vibration damping pads can absorb the vibration generated when the air supply unit is working. The vibration damping bushing assemblies install the mounting bracket and the air supply unit into the vehicle with vibration damping. It can simultaneously control the vibration generated when the air supply unit is working and the vibration when the vehicle is driving, thus meeting the installation and use requirements of the air supply unit.

[0005] Preferably, a spring seat is installed on the inner side of the first support pad, corresponding to the position of the support spring. The support spring is disposed between the spring seat and the first damping pad. The spring seat can limit the support spring and prevent the support spring from deflecting.

[0006] Preferably, the spring seat is connected to the first bracket pad by passing through the first bracket pad with the first snap-fit ​​post, which facilitates quick disassembly and installation of the spring seat and the first bracket pad.

[0007] Preferably, the second vibration damping pad is connected to the second support plate through several second snap-fit ​​posts passing through the second support plate. The second snap-fit ​​posts facilitate the quick disassembly and installation of the second vibration damping pad and the second support plate.

[0008] Preferably, the first vibration damping pad is provided with an annular seat through a hole in the mounting bracket, and the bracket bolt passes through the annular seat. The annular seat can realize the connection and installation of the first vibration damping pad and the mounting bracket without the need for other separate fasteners, making installation convenient. At the same time, the annular seat can also limit the position of the bracket bolt.

[0009] Preferably, a support column is sleeved on the outside of the bracket bolt, and the two ends of the support column abut against the first bracket pad and the second bracket pad, respectively. The support column can protect and guide the bracket bolt, and can limit the distance between the first bracket pad and the second bracket pad, thereby improving the vibration damping connection effect.

[0010] Preferably, the first damping pad has several supporting protrusions arranged on the side facing the first support plate and the second damping pad has several supporting protrusions on the side facing the mounting bracket. The supporting protrusions can improve the strength of the first damping pad and the second damping pad, and play a buffering role when the first damping pad collides with the first support plate and when the second damping pad collides with the mounting bracket.

[0011] Preferably, the vibration damping bushing assembly includes a vibration damping bushing core and a vibration isolation bushing kit axially embedded inside the vibration damping bushing core. The vibration isolation bushing kit allows connecting bolts to pass through, and the vibration damping bushing core plays a vibration damping role.

[0012] Preferably, the mounting bracket has a flanged portion at the opening corresponding to the inner core of the vibration damping bushing. The flanged portion is embedded in the groove on the outer side of the inner core of the vibration damping bushing. The flanged portion can improve the installation strength of the inner core of the vibration damping bushing and prevent deformation.

The system includes a first damping pad 6, a mounting bracket 1, a second damping pad 3, and a second bracket pad 7, with bracket bolts 4. Several damping bushing assemblies 5 are provided at the edge of the mounting bracket 1. By using the first bracket pad 2, the first damping pad 6, the bracket spring 9, the second damping pad 3, and the second bracket pad 7, the air supply unit can be provided with damping support. The first damping pad 6 and the second damping pad 3 can absorb the vibration generated during the operation of the air supply unit. The damping bushing assemblies 5 install the mounting bracket 1 and the air supply unit into the vehicle with damping, simultaneously controlling the vibration generated during the operation of the air supply unit and the vibration during vehicle travel, thus meeting the installation and usage requirements of the air supply unit.

[0026] Specifically, the vibration damping bushing assembly 5 can be installed on the adjacent sides of the mounting bracket 1 respectively. The vibration damping bushing assembly 5 has an axially passing mounting bolt, which can be installed inside the car. The air supply unit is installed on the upper side of the mounting bracket 1 and is installed by the bracket bolt 4. The first vibration damping pad 6 and the second vibration damping pad 3 wrap around the mounting bracket 1. The bracket spring 9 can dampen the vibration between the first vibration damping pad 6 and the first bracket pad 2.

[0027] Meanwhile, in this embodiment, such as Figure 4-6 As shown, a spring seat 10 is installed on the inner side of the first support pad 2 at a position corresponding to the support spring 9. The support spring 9 is positioned between the spring seat 10 and the first damping pad 6. The spring seat 10 can limit the position of the support spring 9 to prevent it from deflecting. The spring seat 10 is connected to the first support pad 2 via a first snap-fit ​​post 15 passing through it, facilitating quick disassembly and installation of the spring seat 10 and the first support pad 2.

[0028] In this embodiment, as Figure 6 As shown, the second vibration damping pad 3 is connected to the second support pad 7 by several second snap-on posts 14 passing through the second support pad 7.

The support column 8 can protect and guide the bracket bolt 4, and can limit the distance between the first bracket pad 2 and the second bracket pad 7, improving the vibration damping connection effect.

[0030] In this embodiment, as Figure 7 As shown, the first damping pad 6 facing the first support plate 2 and the second damping pad 3 facing the mounting bracket 1 are both provided with a number of supporting protrusions 16. The supporting protrusions 16 can improve the strength of the first damping pad 6 and the second damping pad 3, and play a buffering role when the first damping pad 6 collides with the first support plate 2 and the second damping pad 3 collides with the mounting bracket 1.

[0031] In this embodiment, as Figure 5 As shown, the vibration damping bushing assembly 5 includes a vibration damping bushing inner core 12 and a vibration isolation bushing 17 axially embedded inside the vibration damping bushing inner core 12. The vibration isolation bushing 17 can be passed through by connecting bolts, and the vibration damping bushing inner core 12 plays a vibration damping role.

[0032] The mounting bracket 1 has a flange 13 at the opening corresponding to the inner core 12 of the vibration damping bushing. The flange 13 is embedded in the groove on the outside of the inner core 12 of the vibration damping bushing. The flange 13 can improve the installation strength of the inner core 12 of the vibration damping bushing and prevent deformation.

[0033] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0034] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.
