Description

Technical Field

[0001] This utility model relates to the field of automotive shock absorber technology, and in particular to an automotive flat sawtooth integrated module H-beam shock absorber. Background Technology

[0002] In the field of automotive shock absorption, I-beam damping pads have become a widely used key component due to their simple structure and good load-bearing capacity. Traditional I-beam damping pads typically employ a uniformly symmetrical wave-shaped or planar support structure design, and their damping principle mainly relies on the deformation of elastic materials to absorb and disperse vibration energy.

[0003] However, traditional I-shaped shock-absorbing pads have the following significant shortcomings: Firstly, uneven stress distribution and fatigue risk: Traditional symmetrical wave-shaped or planar support structure designs are prone to stress concentration in specific local areas under high-frequency vibration or extreme load conditions. This uneven stress distribution can easily lead to premature local fatigue fracture of the material, seriously affecting the service life and reliability of the shock-absorbing pad.

[0004] Secondly, there is insufficient adaptability to multi-directional vibration and low energy dissipation efficiency: conventional wave-shaped or planar support structures are poorly adaptable to vibrations from different directions (especially vibrations from non-primary force directions). Their energy dissipation paths are relatively simple and fixed, making it difficult to effectively cope with complex and changing road conditions, resulting in poor overall vibration reduction performance, especially in suppressing multi-directional composite vibrations.

[0005] In summary, the existing I-shaped vibration damping pads suffer from uneven stress distribution and fatigue risk, insufficient adaptability to multi-directional vibration, and low energy dissipation efficiency. Utility Model Content

[0006] This utility model provides an automotive flat sawtooth integrated module H-beam shock absorber pad, which can solve the problems of uneven stress distribution and fatigue risk, insufficient multi-directional vibration adaptability and low energy dissipation efficiency of existing H-beam shock absorber pads.

[0007] A car flat sawtooth integrated module H-beam shock absorber pad includes an annular shock absorber pad body, with annular protruding units distributed on both end faces of the annular shock absorber pad body, and the annular protruding units are concentrically arranged with the annular shock absorber pad body. The annular protrusion unit is composed of several independently arranged serrated protrusions.

[0008] Furthermore, the vertical cross-section of the annular shock-absorbing pad body is I-shaped.

[0009] Furthermore, the annular protrusions on the two end faces of the annular shock-absorbing pad body are symmetrically distributed.

[0010] Furthermore, each corner of the annular shock-absorbing pad body is provided with a rounded transition.

[0011] Furthermore, in the annular protrusion unit, the connection position between two adjacent sawtooth protrusions is arranged in an arc shape.

[0012] Furthermore, in the annular protrusion unit, the height of each of the serrated protrusions is equal.

[0013] Furthermore, the serrated protrusions extend from the inner surface of the annular damping pad body to the outer surface of the annular damping pad body.

[0014] Furthermore, the extending direction of the serrated protrusions matches the radial direction of the annular shock-absorbing pad body.

[0015] Furthermore, each corner of the serrated protrusion is provided with a rounded transition.

[0016] Furthermore, the number of the serrated protrusions is 10-20.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides an automotive flat sawtooth integrated module I-beam shock absorber. Both end faces of the annular shock absorber body are distributed with annular protrusion units, and the annular protrusion units are composed of several independently arranged sawtooth protrusions. In this automotive flat sawtooth integrated module I-beam shock absorber structure, each arranged sawtooth protrusion can serve as a small buffer unit. When subjected to impact or pressure, each sawtooth protrusion can independently undergo elastic deformation and absorb energy. Attached Figure Description

[0020] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0021] like Figures 1 to 2 As shown, the present invention provides an automotive flat sawtooth integrated module H-beam shock absorber, including an annular shock absorber body 1, with annular protrusion units 2 distributed on both end faces of the annular shock absorber body 1, and the annular protrusion units 2 and the annular shock absorber body 1 being concentrically arranged. The annular protrusion unit 2 is composed of several independently set serrated protrusions 21; in this automotive flat serrated integrated module I-beam shock absorber structure, each set serrated protrusion 21 can serve as a small buffer unit. When subjected to impact or pressure, each serrated protrusion 21 can independently undergo elastic deformation to absorb energy. That is, the annular protrusion unit 2 is composed of several independently arranged sawtooth protrusions 21 and arranged in a ring. Specifically, the annular protrusion unit 2 is formed by connecting several independently arranged sawtooth protrusions 21 end to end. Furthermore, the serrated protrusion 21 has a serration angle of 20-40°, preferably 30°, and the serration angle refers to the wedge angle of the serrated protrusion 21. Multiple serrated protrusions 21 connected end-to-end form an annular protrusion unit. This annular structure allows the impact force of the automotive flat serrated integrated modular I-beam shock absorber to be transmitted and dispersed along the annular path between adjacent serrated protrusions 21 when subjected to impact. This structure effectively distributes concentrated loads across a larger area of ​​protrusions (i.e., multiple serrated protrusions 21), avoiding excessive local stress and significantly improving overall buffering and energy absorption efficiency. Since grooves are naturally formed between two adjacent serrated protrusions 21, the serrated protrusions 21 are provided with sufficient deformation space when under pressure, which enhances the elastic recovery ability and energy absorption capacity. In addition, the annular protrusion units 2 distributed on the two end faces of the annular shock-absorbing pad body 1 increase the friction with the contact surface, provide a good anti-slip effect, and enhance the stability of the shock-absorbing pad during use. The annular damping pad body 1 and the annular protrusion unit 2 are designed as a single piece, which enhances the consistency of the damping pad structure.

[0022] like Figures 1 to 2 As shown, in some embodiments of this utility model, the material of the annular shock-absorbing pad body 1 and the annular protrusion unit 2 can be rubber or thermoplastic elastomer to ensure its wear resistance and anti-aging performance.

[0023] like Figures 1 to 2As shown, in some embodiments of this utility model, the cross-section of the serrated protrusion 21 is trapezoidal. Specifically, the end of the serrated protrusion 21 that is close to the annular shock-absorbing pad body 1 is designated as the proximal end, and the end of the serrated protrusion 21 that is far from the annular shock-absorbing pad body 1 is designated as the distal end; the area of ​​the trapezoid gradually increases from the distal end to the proximal end. The side of the serrated protrusion 21 away from the end face of the annular shock-absorbing pad body 1 is the tip, and the tip is set in an arc shape. That is, the serrated protrusion 21 has a serrated shape and a trapezoidal cross-section. The area of ​​the trapezoid gradually increases from the far end to the near end. This allows the serrated protrusion 21 to deform in stages along the height direction during impact. At the initial contact, the small cross-section deforms first to alleviate high-frequency impact. As the load increases, the large cross-section gradually participates in bearing the load to avoid sudden stress changes. The plurality of sawtooth protrusions 21 form a ring layout. Combined with the fact that the area of ​​the trapezoid gradually increases from the far end to the near end, the sawtooth protrusions 21 have inclined surfaces. When subjected to impact force, the inclined surfaces of the sawtooth protrusions 21 provide structural support and suppress their deformation. That is, the gradual area change design of the sawtooth protrusions 21 optimizes the energy transfer path under asymmetric loads. This design reduces the risk of localized deformation, thereby extending the service life of the shock-absorbing pad.

[0024] like Figures 1 to 2 As shown, in some embodiments of this utility model, the vertical cross-section of the annular shock-absorbing pad body 1 is I-shaped; That is, the overall shape of the annular shock-absorbing pad body 1 adopts the traditional I-shaped shock-absorbing pad.

[0025] like Figures 1 to 2 As shown, in some embodiments of this utility model, the annular protrusion units 2 on the two end faces of the annular shock-absorbing pad body 1 are symmetrically distributed. Since the annular protrusions 2 on the two end faces of the annular damping pad body 1 are symmetrically distributed, when one of the annular protrusions 2 is compressed, the other annular protrusion 2 expands synchronously through mirroring, forming a bidirectional energy transfer channel; under alternating load, the two symmetrically distributed annular protrusions 2 can take turns bearing the load, avoiding continuous fatigue of the material on one side, thereby extending the service life of the damping pad.

[0026] like Figures 1 to 2 As shown, in some embodiments of this utility model, in the annular protrusion unit 2, the connection position between two adjacent sawtooth protrusions 21 is arranged in an arc shape. In the annular protrusion unit 2, the height of each serrated protrusion 21 is equal; Since the height of each serrated protrusion 21 in the annular protrusion unit 2 is equal, and the connection position between two adjacent serrated protrusions 21 is set in an arc shape, forming a continuous connection band, the early cracking problem caused by right angle connection is avoided, and the wave energy can be dissipated in a coordinated manner.

[0027] like Figures 1 to 2 As shown, in some embodiments of this utility model, each corner of the annular shock-absorbing pad body 1 is provided with a rounded transition; this setting can effectively reduce the stress concentration coefficient of the edge, so that the external impact force can be uniformly transmitted through the continuous curved surface.

[0028] like Figures 1 to 2 As shown, in some embodiments of this utility model, the serrated protrusions 21 extend from the inner surface of the annular shock-absorbing pad body 1 to the outer surface of the annular shock-absorbing pad body 1. The serrated protrusions 21 extend in the same direction as the radial direction of the annular damping pad body 1. Since the serrated protrusions 21 extend from the inner surface of the annular damping pad body 1 to the outer surface of the annular damping pad body 1, they help to distribute the load applied to the annular damping pad body 1 more evenly across the entire contact surface, reduce pressure peaks, and prevent local collapse or damage to the annular damping pad body 1.

[0029] like Figures 1 to 2 As shown, in some embodiments of this utility model, each corner of the serrated protrusion 21 is provided with a rounded transition; this arrangement, when subjected to pressure deformation, better forms a gradual contact surface and avoids abrupt deformation.

[0030] like Figures 1 to 2 As shown, in some embodiments of this utility model, the number of serrated protrusions 21 is 10-20; the number of serrated protrusions 21 is preferably 12.

[0031] This utility model provides an automotive flat sawtooth integrated module H-beam shock absorber pad, which effectively suppresses high-frequency resonance and low-frequency vibration through multi-directional energy dissipation; the design of several independently set sawtooth protrusions 21 avoids stress concentration and significantly enhances fatigue resistance.
