Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment support technology, and in particular to a shock-absorbing support. Background Technology
[0002] In automotive braking systems, vacuum boosters generate an assist effect through negative pressure within their chambers, making them a core component for ensuring safe braking of vehicles. Vacuum pumps, as the power source for vacuum boosters, function to expel air from the booster chambers, creating a negative pressure environment within the chambers, thereby amplifying the force of the brake pedal and reducing the driver's workload.
[0003] However, during vehicle operation, the vacuum pump motor inevitably generates regular vibrations under high-frequency operating conditions. These vibrations and the resulting noise will form a transmission path through rigid connecting components such as the vacuum pump bracket and the car chassis, and will eventually be transmitted to the cockpit. This not only reduces driving comfort but also poses potential safety hazards. Utility Model Content
[0004] The purpose of this invention is to provide a shock-absorbing bracket that effectively suppresses the vibration transmission of a vacuum pump motor and reduces noise interference, thereby effectively solving the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A shock absorber bracket includes a bracket body, which further includes a frame connection portion and a vacuum pump connection portion. A connecting pad is fixedly installed on one side of the frame connection portion, and a plurality of frame connection shock absorbers are fixedly installed on one side of the connecting pad. Two of the frame connection shock absorbers are fixedly connected to the connecting pad, and two other frame connection shock absorbers are fixedly connected to the connecting pad, respectively, to a first connecting block. A vacuum pump vent hole is provided in the vacuum pump connection portion, and a plurality of first fixing holes are also provided in the vacuum pump connection portion. The plurality of first fixing holes are arranged in a ring along the outline of the vacuum pump vent hole. A vacuum pump connection shock absorber is fixedly installed in the first fixing hole. The vacuum pump connection shock absorber includes two first pads, and a third connecting block is fixedly connected between the two first pads.
[0007] As a further preferred embodiment of this utility model, the frame connecting part and the vacuum pump connecting part are in an L-shaped structure. Two second fixing holes are provided on one side of the frame connecting part. The second fixing holes are pill-shaped. Two third fixing holes are provided on the other side of the frame connecting part. The provision of the second fixing holes and the third fixing holes allows the frame connecting part to be installed on the frame with bolts. The pill-shaped second fixing holes can compensate for the deviation of the frame mounting hole position, so that the frame connecting part can be stably installed on the frame.
[0008] As a further preferred embodiment of this utility model, two reinforcing ribs are fixedly connected at the inner angle between the frame connection part and the vacuum pump connection part. Connecting the frame connection part and the vacuum pump connection part with reinforcing ribs can improve the connection strength between the frame connection part and the vacuum pump connection part, and improve the stability of the vacuum pump connection part after the vacuum pump is installed.
[0009] As a further preferred embodiment of this utility model, a fourth fixing hole is provided between the two frame connecting shock-absorbing pads and the second connecting block and connecting gasket, respectively. The longitudinal section of the second connecting block is the same as the second fixing hole. A fifth fixing hole is provided between the other two frame connecting shock-absorbing pads and the first connecting block and connecting gasket, respectively. The longitudinal section of the first connecting block is the same as the third fixing hole. The fourth fixing hole is the same as the second fixing hole. The second connecting block is fitted into the corresponding second fixing hole, and the first connecting block is fitted into the corresponding third fixing hole. The connecting gasket and the frame connecting shock-absorbing pad are provided on one side of the frame connecting part, which can reduce the vibration transmission of the bracket body to the frame. The semi-enclosed setting of the connecting gasket relative to the side of the frame connecting part can increase the contact area between the frame connecting part and the frame, distribute the bolt preload to a larger range, and avoid excessive local pressure. This can prevent the connecting gasket from deforming under force when the frame connecting part is connected to the frame, which would cause the frame connecting part to contact the frame and transmit vibration.
[0010] As a further preferred embodiment of this utility model, the first pad has multiple hollow cavities, a second pad is fixedly installed at one end of the first pad, and a third connecting block is snapped into the corresponding first fixing hole. The two first pads are located at the top and bottom of the vacuum pump connection part, respectively. The third connecting block and the two first pads and the second pad have a connected sixth fixing hole. By setting multiple vacuum pump connection damping pads between the vacuum pump connection part and the vacuum pump mounting bracket, the transmission of vacuum pump vibration to the vacuum pump connection part can be reduced. Moreover, the first pad of the vacuum pump connection damping pad has multiple hollow cavities, which reduces the amount of material used and the weight of the vacuum pump connection damping pad. At the same time, the synergistic effect of the hollow cavities and the vacuum pump connection damping pad material achieves efficient vibration reduction.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] In this invention, by setting a connecting gasket and multiple frame connecting shock-absorbing pads at the frame connection part of the bracket body, along with a first connecting block and a second connecting block, the vibration transmission between the bracket body and the frame can be reduced. At the same time, the hollow cavity opened in the vacuum pump connecting shock-absorbing pad of the vacuum pump connection part reflects and interferes with the vibration wave, which can reduce the transmission of vibration generated by the operation of the vacuum pump to the bracket body, thereby realizing a two-stage shock absorption process and effectively reducing the transmission of vibration from the operation of the vacuum pump to the frame.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figures 1-5 As shown, the present invention provides a shock-absorbing bracket, including a bracket body 1. The bracket body 1 also includes a frame connection part 19 and a vacuum pump connection part 20. A connecting gasket 2 is fixedly installed on one side of the frame connection part 19. Multiple frame connection shock-absorbing pads 4 are fixedly installed on one side of the connecting gasket 2. Two frame connection shock-absorbing pads 4 and the connecting gasket 2 are respectively fixedly connected to a first connecting block 3. The other two frame connection shock-absorbing pads 4 and the connecting gasket 2 are respectively fixedly connected to a first connecting block 3. A vacuum pump vent hole 6 is opened in the vacuum pump connection part 20. Multiple first fixing holes 7 are also opened in the vacuum pump connection part 20, and the multiple first fixing holes 7 are arranged in a ring along the outline of the vacuum pump vent hole 6. A vacuum pump connection shock-absorbing pad 8 is fixedly installed in the first fixing hole 7. The vacuum pump connection shock-absorbing pad 8 includes two first pads 9. A third connecting block 10 is fixedly connected between the two first pads 9.
[0021] like Figures 1-2As shown, two reinforcing ribs 11 are fixedly connected at the inner angle between the frame connection part 19 and the vacuum pump connection part 20. Connecting the frame connection part 19 and the vacuum pump connection part 20 with the reinforcing ribs 11 can improve the connection strength between the frame connection part 19 and the vacuum pump connection part 20 and improve the stability of the vacuum pump connection part 20 after the vacuum pump is installed.
[0022] like Figures 2-5 As shown, the frame connection part 19 and the vacuum pump connection part 20 have an L-shaped structure. Two second fixing holes 12, shaped like pills, are provided on one side of the frame connection part 19. Two third fixing holes 13 are provided on the other side of the frame connection part 19. The provision of the second fixing holes 12 and third fixing holes 13 allows the frame connection part 19 to be installed onto the frame using bolts. The pill-shaped second fixing holes 12 can compensate for deviations in the frame mounting hole positions, ensuring that the frame connection part 19 can be stably installed onto the frame. The two frame connecting shock absorbers 4 and the second connecting block 5 are connected... A fourth fixing hole 14 is provided between the connecting pads 2. The longitudinal section of the second connecting block 5 is the same as that of the second fixing hole 12. A fifth fixing hole 15 is provided between the two frame connecting shock absorbers 4 and the first connecting block 3 and connecting pads 2. The longitudinal section of the first connecting block 3 is the same as that of the third fixing hole 13. The fourth fixing hole 14 is the same as that of the second fixing hole 12. The second connecting block 5 is fitted into the corresponding second fixing hole 12, and the first connecting block 3 is fitted into the corresponding third fixing hole 13. A connecting pad 2 and a frame connecting shock absorber 4 are provided on one side of the frame connecting part 19, which can reduce the height of the bracket body. The vibration transmission of the frame is controlled by the semi-enclosed arrangement of the connecting gasket 2 relative to the side of the frame connection 19, which increases the contact area between the frame connection 19 and the frame, and distributes the bolt preload over a wider range, avoiding excessive local pressure. This prevents the connecting gasket 2 from deforming under stress when the frame connection 19 is connected to the frame, thus preventing vibration transmission due to contact between the frame connection 19 and the frame. The first gasket 9 has multiple hollow cavities 16, and a second gasket 17 is fixedly installed at one end of the first gasket 9. The third connecting block 10 is snapped into the corresponding first fixing hole 7. The two first gaskets 9 are respectively located at... At the top and bottom of the vacuum pump connection part 20, the third connecting block 10 and the two first pads 9 and the second pad 17 are provided with a sixth fixing hole 18. Multiple vacuum pump connection damping pads 8 are set between the vacuum pump connection part 20 and the vacuum pump mounting bracket, which can reduce the transmission of vacuum pump vibration to the vacuum pump connection part 20. In addition, the first pad 9 of the vacuum pump connection damping pad 8 is provided with multiple hollow cavities 16. The hollow cavities 16 reduce the amount of material used and reduce the weight of the vacuum pump connection damping pad 8. At the same time, the synergistic effect of the hollow cavity 16 and the vacuum pump connection damping pad 8 material achieves efficient vibration reduction.
[0023] It should be noted that this utility model is a shock-absorbing bracket. First, the third connecting block 10 between the two first pads 9 of the vacuum pump connecting shock-absorbing pad 8 is snapped into the corresponding first fixing hole 7. Then, the remaining vacuum pump connecting shock-absorbing pads 8 are operated in the same manner as described above, so that four sets of first pads 9 and second pads 17 are respectively provided at the top and bottom of the vacuum pump connecting part 20. Then, the vacuum pump is inserted into the vacuum pump clearance hole 6, and the outer mounting bracket of the vacuum pump is placed on the four second pads 17, and the vacuum... The mounting holes of the pump mounting bracket are aligned with the corresponding sixth fixing hole 18. Then, the vacuum pump can be connected and fixed by passing through the outer mounting bracket of the vacuum pump and the corresponding sixth fixing hole 18, thereby completing the connection between the vacuum pump and the vacuum pump connection part 20. Then, place one side of the frame connection part 19 on the frame and make the connecting gasket 2 side abut against the frame. Then, first, two bolts can be passed through the fifth fixing hole 15 and fixed on the frame. Then, the other two bolts can be passed through the fourth fixing hole 14 and installed on the frame.
[0024] When the vacuum pump motor vibrates, the vibration is first transmitted to multiple vacuum pump connection damping pads 8. Each vacuum pump connection damping pad 8 consists of two first pads 9, two second pads 17, and a third connecting block 10. Multiple hollow cavities 16 within the first pads 9 can dissipate energy through air compression and expansion, vibration wave reflection and interference, and extend the propagation path. Combined with the internal friction of material deformation, this reduces the transmission of vibration to the vacuum pump connection part 20. Subsequently, a small amount of vibration that is not completely absorbed is transmitted to the frame connection part 19. The frame connection damping pads 4 on both sides of the connecting pad 2 further dissipate vibration energy through elastic deformation. Furthermore, the semi-enclosed structure of the connecting pad 2 increases the contact area with the frame, disperses the bolt preload, avoids excessive local pressure, and prevents the frame connection part 19 from directly contacting the frame and transmitting vibration.
