[0003] However, the existing shock absorber assembly also has significant defects: first, the base is made of metal, and if the contact surface of the rubber vulcanized to the metal seat is too large, it will require a larger size, and a smaller contact surface will affect the durability of the vulcanization point, so the contact area of ​​the vulcanization point should not be too large or too small. In addition, the mass block is embedded in the rubber, which can both reduce the vibration frequency and attenuate the vibration, but it is difficult to solve the vibration problem of different models by changing the weight of the mass block, and the scope of application is narrower.

[0026] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0027] Reference below Figure 1-Figure 3 A vibration absorber assembly 1 according to an embodiment of the present invention is described.

[0028] like Figure 1 As shown, the vibration absorber assembly 1 according to the embodiment of the utility model includes: a vibration absorber 10 and a mass block assembly 20. The vibration absorber 10 is a main component of the vibration absorber assembly 1. The vibration absorber 10 can attenuate the vibration of the body and the kinetic energy transmitted to itself through the vibration of the body part. The vibration absorber 10 is set to be cylindrical. The mass block assembly 20 is a component of the vibration absorber assembly 1, which can reduce the noise in the high frequency range.

[0029] like Figure 2As shown, the mass block assembly 20 includes: a first mass block 200 and a second mass block 201 . The first mass block 200 is disposed on one side of the vibration absorbing member 10 , and the first mass block 200 is provided with a mounting portion 202 . The second mass block 201 is disposed in the vibration absorbing member 10 . The first mass block 200 and the second mass block 201 are both components of the mass block assembly 20. The first mass block 200 is arranged on one side of the vibration absorber 10, which can reduce high-frequency noise, eliminate howling mutations, reduce transfer function, improve NVH performance of the whole vehicle, and widen the frequency range of use of the vibration absorber assembly 1. In addition, the vulcanization range of the vibration absorber 10 and the first mass block 200 can be increased to improve the durability of the vibration absorber assembly 1. The first mass block 200 is provided with a mounting portion 202, which can maintain the convenience of assembly on the basis of a wider frequency range of use. The second mass block 201 is arranged in the vibration absorber 10, so that the second mass block 201 plays the role of the vibration absorber 10, and absorbs vibrations together with the vibration absorber 10 to eliminate resonance, thereby further improving the vibration absorption effect of the vibration absorber assembly 1.

[0030] Therefore, by setting the first mass block 200 on one side of the vibration absorber 10 and the second mass block 201 inside the vibration absorber 10, high-frequency noise can be reduced, and at the same time, the howling mutation can be eliminated, the transfer function can be reduced, the NVH performance of the whole vehicle can be improved, and the frequency range of the vibration absorber assembly 1 can be widened. Secondly, the vulcanization range of the vibration absorber 10 and the first mass block 200 can be increased, and the durability of the vibration absorber assembly 1 can be improved. In addition, the first mass block 200 is provided with a mounting portion 202, so that the convenience of assembly can be maintained on the basis of a wider frequency range of use.

[0031] Specifically, Figure 2 As shown, the first mass block 200 includes: a main body section 203 and a mounting section 204, the main body section 203 is connected to the vibration absorbing member 10, the mounting section 204 is connected to one end of the main body section 203 away from the vibration absorbing member 10, the mounting section 204 is provided with a mounting portion 202, and a fastener passes through the vibration absorbing member 10 and the main body section 203 and is fixed to the mounting portion 202. It should be noted that the main section 203 is the main part of the first mass block 200 and can be used to connect and set other components. The mounting section 204 is mainly used for installation. The main section 203 is connected to the vibration absorbing member 10, and the mounting section 204 is connected to the end of the main section 203 away from the vibration absorbing member 10. At this time, the main section 203, the vibration absorbing member 10, and the mounting section 204 form a whole, which is convenient for the first mass block 200 to be set on one side of the vibration absorbing member 10. The mounting portion 202 can be mainly used for installation. At this time, the fastener passes through the vibration absorbing member 10 and the main section 203 and is fixed to the mounting portion 202, thereby setting the first mass block 200 on one side of the vibration absorbing member 10.

[0032] Among them, Figure 2As shown, the mounting section 204 is constructed as a nut structure, and the mounting portion 202 is constructed as a threaded hole structure. The nut structure has high precision, high load bearing capacity, good thermal conductivity and corrosion resistance, and can meet the needs of various industrial applications. The mounting section 204 is constructed as a nut structure, which can improve the convenience and firmness of assembly. The mounting portion 202 is constructed as a threaded hole structure. At this time, the fastener can be passed through the vibration absorbing member 10 and the main section 203 can be fixed to the mounting portion 202, so that the first mass block 200 is set on one side of the vibration absorbing member 10. Among them, the head of the mounting section 204 can be made into a flange hexagonal head shape, and the size of the flange hexagonal head should correspond to the size of the threaded hole. The fastener can be a double-headed stud, and the main section 203 is cylindrical.

[0033] In addition, if Figure 2 As shown, the mounting section 204 is integrally formed on the main section 203. That is, the mounting section 204 is integrated with the main section 203, so that the first mass block 200 can be formed into an integral structure, which can make the structure of the first mass block 200 more stable and firm, and is easy to install and set, and only one processing mold is needed, which is easy to produce.

[0034] Of course, if Figure 2 As shown, the first mass block 200 and the second mass block 201 are both steel structures. Steel structures have light weight, high bearing capacity, good sealing performance, good durability and good shock resistance. The first mass block 200 and the second mass block 201 are both set as steel structures, so that the structure of the mass block assembly 20 can be more in line with actual working conditions.

[0035] Furthermore, if Figure 2 As shown, there are multiple second mass blocks 201, and the multiple second mass blocks 201 are arranged at intervals in the vibration absorber 10. Multiple second mass blocks 201 can be arranged in the vibration absorber 10, and the multiple second mass blocks 201 play the role of the vibration absorber 10, absorb vibrations together with the vibration absorber 10, eliminate resonance, and further improve the vibration absorption effect of the vibration absorber assembly 1, which can reduce high-frequency noise, eliminate howling mutations, reduce transfer functions, improve the NVH performance of the whole vehicle, and widen the frequency range of the vibration absorber assembly 1. The multiple second mass blocks 201 are arranged at intervals in the vibration absorber 10, which can avoid interference between the multiple second mass blocks 201, and at the same time make the distribution range of the multiple second mass blocks 201 wider, which can better eliminate resonance to a certain extent. Of course, the second mass member 201 can also be one.

[0036] In addition, Figure 2As shown, the vibration absorbing member 10 is a rubber member. The rubber member has good comfort and durability, and can improve efficiency. The vibration absorbing member 10 is set as a rubber member, so that the vibration absorbing member 10 can attenuate the vibration of the rubber member body and the kinetic energy transmitted to itself through the vibration of the rubber member body, thereby solving the problem of high-frequency howling and sudden howling of the motor.

[0037] It should be noted that if Figure 3 As shown, the rubber member is vulcanized on the first mass block 200. In this way, the vulcanization range of the vibration absorber 10 and the first mass block 200 can be increased, the vibration absorber assembly 1 is integrated, and the durability of the vibration absorber assembly 1 is improved.

[0038] The power system according to the embodiment of the utility model comprises: a powertrain, a suspension and the vibration absorber assembly 1 described in the above embodiment, wherein the vibration absorber assembly 1 is arranged between the powertrain and the suspension. In this way, the vibration absorber assembly 1 can attenuate the vibration generated by the powertrain and transmitted to the suspension, thereby making the suspension work more stably and reliably.
