The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

The vehicle may be classified into a mini-vehicle, a light-vehicle, a medium-vehicle, a high-vehicle, etc. according to the displacement of the engine, and is not particularly limited.

Alternatively, the vehicle body is made of a material with high structural strength, specifically, a metal material, such as aluminum, aluminum alloy, magnesium alloy, iron alloy, and the like, high-strength plastic, ceramic, carbon fiber, and the like.

Optionally, the damper assembly is adapted to be coupled to a suspension of the vehicle body and may also function to dampen vibrations in a passive response state of the active suspension. The passive response state of the active suspension refers to that when the active suspension system fails or fails, the suspension system is degraded into a traditional passive suspension system, i.e. the active adjustment and control capability is no longer provided, and the road impact can be absorbed and buffered only by the inherent characteristics of the suspension.

Alternatively, the orthographic projection of the second shim 26 onto the first shim 22 is entirely within the first shim 22.

Optionally, since the load of the shock absorber 10 in the jump up is far greater than the load of the jump down, the first gasket 22 plays a bearing role when the shock absorber 10 jumps up, and the second gasket 26 plays a bearing role when the shock absorber 10 jumps down, so the area of the second gasket 26 is smaller than that of the first gasket 22 (in the direction along the orthographic projection of the second gasket 26 on the first gasket 22), the load of the shock absorber 10 in the jump up/down can be well borne, and the service life of the top glue structure 20 is effectively prolonged.

At the same time, mounting plate 24 prevents first spacer 22 from directly contacting second spacer 26, preventing the two from affecting each other, and reducing the damping effect of shock absorber 10.

By providing the area of the orthographic projection of the mounting plate 24 on the first shim 22 to be larger than the area of the orthographic projection of the second shim 26 on the first shim 22, the first shim 22 and the second shim 26 are made to bear the load of the shock absorber 10 when jumping up/down, respectively, while preventing the first shim 22 and the second shim 26 from affecting each other.

Alternatively, the inner wall surface of the fixing hole 233 is fixed to the connection structure 12 by screw-coupling.

Through setting up the cylinder portion 231 and having seted up fixed orifices 233, fixed orifices 233 and connection structure 12 cooperation are connected to make retaining member 23 and connection structure 12 fixed, and then fixed top glued structure 20's position, avoid top glued structure 20 to float and influence the damping effect.

Optionally, the top glue structure 20 further includes a buffer layer (not shown in the figure) disposed on a side of the bottom plate 21 facing the top plate 11.

Alternatively, the material of the buffer layer may be Butadiene Rubber (BR), natural Rubber (NR), styrene-butadiene rubber (SBR), or the like, which is not particularly limited.

Optionally, the buffer layer is integrally connected with the surface of the bottom plate 21, which faces the top plate 11, through a vulcanization process, and the buffer layer contacts with the top plate 11, so that the influence of assembly gaps caused by the contact between the bottom plate 21 and the top plate 11 and the process errors of the processing of parts per se can be eliminated, and meanwhile, the noise between the top glue structure 20 and the shock absorber 10 can be reduced.

The following describes a top-pressure structure 20 and its working principle in an embodiment of the present application.

Referring to fig. 1 and 5, fig. 1 is a ball screw motor damper assembly 100. In the running process of the vehicle, the shock absorber 10 is not in a working state at all times, when the whole vehicle is impacted and bears the amplitude of high-frequency low vibration, the spring 13 of the shock absorber 10 is not compressed or only slightly compressed, at the moment, vibration is transmitted to the top rubber structure 20 from the shock absorber 10 through the connecting structure 12 at the top, and after the top rubber structure 20 absorbs and buffers part of force through the first gasket 22 and the second gasket 26, the residual part of tiny force after attenuation is transmitted to the vehicle body, so that the energy absorption effect is achieved. Under this action, when the active electromagnetic suspension is in a passive response state, the top rubber structure 20 can also play a role in assisting the vibration reduction of the vibration absorber 10, and the adjustment of the suspension posture is easier while the riding comfort of passengers is improved.

In the description of the embodiments of the present application, it should be noted that, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like refer to the orientation or positional relationship described based on the drawings, which are merely for convenience of description and simplification of the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

The above disclosure is only a preferred embodiment of the present application, and it should be understood that the scope of the application is not limited thereto, but all or part of the procedures for implementing the above embodiments can be modified by one skilled in the art according to the scope of the appended claims.
