Description

Technical Field

[0001] This utility model relates to the field of vibration absorption component technology, and in particular to a vibration absorption component and a vehicle. Background Technology

[0002] Vertical resonance of the automotive axle is one of the major causes of vibration inside the vehicle. To address this issue, a rear axle vertical vibration absorber is typically designed during the vehicle development process. The absorber's modal frequency coincides with the rear axle's vertical pitch mode, thus absorbing the vibration energy generated during rear axle resonance.

[0003] In related technologies, during the automotive R&D process, the rear axle pitch mode frequency is obtained through simulation or experimentation, and a vibration absorber is designed based on this frequency characteristic. However, due to simulation or experimental errors, the vibration absorber's mode frequency may not perfectly match the rear axle pitch mode frequency. In this case, the frequency value needs to be corrected, and the vibration absorber needs to be redesigned and tested until a perfect match is achieved. This iterative process of correcting and refining the vibration absorber is time-consuming and labor-intensive, leading to a significant increase in R&D costs. Furthermore, for each new vehicle, a vibration absorber adapted to that specific vehicle needs to be repeatedly developed. The absorption frequency of the vibration absorber is difficult to adjust, resulting in further time and effort commitments and a substantial increase in R&D costs. Utility Model Content

[0030] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0031] The following is for reference. Figures 1-4 The present invention describes a vibration-absorbing component 100 according to an embodiment of the present invention, and also proposes a vehicle.

[0032] Reference Figure 1 and Figure 2As shown, the vibration-absorbing component 100 of this embodiment includes a counterweight 10, a connecting member 20, and an elastic member 30, used to adjust the frequency of the vibration-absorbing component 100. The connecting member 20 is disposed below the counterweight 10, and a receiving space is defined between the connecting member 20 and the counterweight 10. The elastic member 30 is disposed within the receiving space and is fixedly connected to the counterweight 10. The counterweight 10 is used to adjust the frequency of the vibration-absorbing component 100. The frequency of the vibration-absorbing component 100 can be adjusted by replacing the counterweight 10 with different weights as needed. The connecting member 20 is used to connect to the rear axle of the vehicle. When the frequency of the vibration-absorbing component 100 matches the modal frequency of the rear axle of the vehicle, the vibration of the vehicle is reduced, and the NVH performance of the vehicle is optimized.

[0033] In addition, the vibration damping assembly 100 also includes an adjusting member 40, which connects the counterweight 10 and the connecting member 20. The adjusting member 40 adjusts the distance between the counterweight 10 and the connecting member 20 to adjust the compression and stiffness of the elastic member 30. The adjusting member 40 passes through the counterweight 10 and the elastic member 30 in sequence and is connected to the connecting member 20. By turning the adjusting member 40, the compression of the elastic member 30 by the counterweight 10 and the connecting member 20 is changed, thereby changing the size and density of the elastic member 30, and thus adjusting the stiffness of the elastic member 30 to adjust the frequency of the vibration damping assembly 100.

[0034] Therefore, the vibration-absorbing component 100 can adjust the compression and stiffness of the elastic element 30 by adjusting the distance between the counterweight 10 and the connecting element 20, thereby adjusting the frequency of the vibration-absorbing component 100 so that the frequency of the vibration-absorbing component 100 matches the modal frequency of the rear axle of the vehicle, thus solving the problem of vibration inside the vehicle caused by axle vibration and improving the NVH performance of the vehicle. There is no need to replace the elastic element 30, reducing the cumbersome process of replacing the counterweight 10 or developing the elastic element 30. On the one hand, it reduces labor costs and R&D costs, making the cost of the vibration-absorbing component 100 more affordable and improving its competitiveness. On the other hand, it reduces the time spent developing the vibration-absorbing component 100, thereby improving work efficiency.

[0035] Among them, the elastic element 30 is a cuboid, and the upper and lower end faces of the elastic element 30 abut against the counterweight 10 and the connecting element 20 respectively.

[0036] Among them, reference Figure 1 and Figure 2 As shown, there are at least two elastic elements 30, which are spaced apart within the receiving space. Thus, by providing at least two elastic elements 30 within the receiving space, the energy absorption and vibration absorption effect of the vibration-absorbing assembly 100 can be improved, thereby enhancing the NVH performance of the vehicle.

[0037] In addition, refer to Figure 4As shown, the connector 20 includes two support plates 21 and a connecting portion 22. The connecting portion 22 is connected between the two support plates 21. The adjusting member 40 is connected to the connecting portion 22. At least two elastic members 30 are respectively disposed on the two support plates 21. That is, support plates 21 are respectively disposed on both sides of the connecting portion 22, and at least two elastic members 30 are respectively disposed on the two support plates 21. In other words, at least one elastic member 30 is disposed between the support plate 21 and the counterweight 10.

[0038] Furthermore, the connecting part 22 protrudes towards the counterweight 10 relative to the two support plates 21, which facilitates the connection between the connecting part 22 and the adjusting part 40, and the connecting part 22 can separate at least two elastic members 30 from each other.

[0039] Combination Figure 3 and Figure 4 As shown, the connecting part 22 has a first mounting hole, the counterweight 10 has a second mounting hole 11, and the adjusting member 40 includes an adjusting screw 41 and an adjusting nut 42. The adjusting screw 41 passes through the first mounting hole and the second mounting hole 11 and is connected to the adjusting nut 42. In other words, the first mounting hole on the connecting part 22 and the second mounting hole 11 on the counterweight 10 enable a fixed connection between the counterweight 10 and the connecting member 20 after the adjusting member 40 passes through the first mounting hole and the second mounting hole 11.

[0040] In addition, the adjusting member 40 includes an adjusting screw 41 and an adjusting nut 42. The relative position between the adjusting nut 42 and the adjusting screw 41 can be adjusted, thereby adjusting the distance between the counterweight 10 and the connecting member 20, and thus adjusting the compression and stiffness of the elastic member 30.

[0041] The adjusting nut 42 and the connecting part 22 are fixedly connected. In this way, the adjusting nut 42 and the connecting part 22 are integrated, which facilitates the fixed connection between the adjusting part 40 and the adjusting nut 42, thereby improving the assembly efficiency of the vibration absorption assembly 100.

[0042] Reference Figure 1 and Figure 2 As shown, the vibration damping assembly 100 further includes a protective pad 51, which is fitted onto the second mounting hole 11. An adjusting screw 41 passes through the protective pad 51, with one end of the adjusting screw 41 facing the counterweight 10 abutting against the protective pad 51. In other words, the protective pad 51, installed in the second mounting hole 11, protects the counterweight 10 and prevents the adjusting screw 41 from damaging it.

[0043] In addition, the protective pad 51 can be a rubber pad, which can play a role in shock absorption and cushioning.

[0044] Furthermore, a 2mm gap is designed between the adjusting screw 41 and the protective pad 51.

[0045] Reference Figure 2 As shown, a first adjusting rod 31 is provided above the elastic member 30, and a first adjusting groove 12 is provided on the counterweight 10. The first adjusting rod 31 is engaged within the first adjusting groove 12 and can move within the first adjusting groove 12. That is to say, by providing the first adjusting groove 12 on the counterweight 10, the first adjusting member 40 of the elastic member 30 can move within the first adjusting groove 12, so that the elastic member 30 can meet different installation positions.

[0046] Thus, the installation position of the elastic element 30 is adjustable, making it easy to adjust the installation position according to different spaces and boundaries.

[0047] And, combined Figure 1 and Figure 2 As shown, the vibration damping assembly 100 also includes a fixing nut 52, which is fixedly connected to the first adjusting rod 31. That is, the vibration damping assembly 100 is also provided with a fixing nut 52 for fixedly connecting to the first adjusting rod 31, so that the elastic element 30 can be fixed to the counterweight 10.

[0048] Furthermore, when adjusting the position of the elastic element 30 on the counterweight 10, the fixed connection between the elastic element 30 and the counterweight 10 is first canceled by unscrewing the fixing nut 52, and then the elastic element 30 is moved to the corresponding position by moving the first adjusting rod 31 in the first adjusting groove 12. Finally, the fixing nut 52 is tightened to achieve a fixed connection between the elastic element 30 and the counterweight 10.

[0049] Among them, combined Figure 2 and Figure 4 As shown, a second adjusting rod 32 is provided below the elastic member 30, and a second adjusting groove 24 is provided on the connecting member 20. The second adjusting rod 32 is engaged within the second adjusting groove 24 and can move within the second adjusting groove 24. That is, by providing a second adjusting groove 24 on the connecting member 20, the second adjusting member 40 of the elastic member 30 can move within the second adjusting groove 24, thus allowing the elastic member 30 to meet different installation positions.

[0050] In other words, a first adjusting rod 31 and a second adjusting rod 32 are respectively provided on the upper and lower sides of the elastic member 30, which can improve the stability of the elastic member 30 in the cooperation between the counterweight 10 and the connecting member 20.

[0051] Furthermore, the implementation principle of the vibration-absorbing component 100 is as follows: the frequency of the vibration-absorbing component 100 can be adjusted by replacing the counterweight 10 or the elastic element 30. When the weight of the counterweight 10 remains unchanged, the frequency of the vibration-absorbing component 100 can be adjusted by changing the appropriate elastic element 30; when the elastic element 30 remains unchanged, the frequency of the vibration-absorbing component 100 can be adjusted by changing the appropriate counterweight 10, i.e., changing the weight of the counterweight 10. The vibration-absorbing component 100 can also adjust its frequency by compressing the elastic element 30. When neither the counterweight 10 nor the elastic element 30 is replaced, the frequency of the vibration-absorbing component 100 can be adjusted by turning the adjusting component 40, which adjusts the distance between the counterweight 10 and the connecting component 20, thereby adjusting the compression amount and stiffness of the elastic element 30.

[0052] The vehicle according to a second aspect of the present invention includes a vibration-absorbing assembly 100.
