Description

Technical Field

[0001] This utility model relates to the field of shock absorption components, specifically to a multi-cavity buffer double-layer shock absorber rubber component. Background Technology

[0002] Shock absorber rubber components are key basic components in the machinery, automotive and other fields. Relying on the good elasticity and damping properties of rubber, they can effectively absorb and buffer the vibration and impact during equipment operation, reduce noise, improve the smoothness of equipment operation, and ensure the safety and reliability of structural components.

[0003] Utility model patent CN222436904U discloses a combined shock-absorbing rubber. This combined shock-absorbing rubber includes a rubber body with a ring-shaped structure. An annular storage groove is formed on the outer surface of the rubber body, and a plurality of internal support blind holes are formed on the inner surface of the annular storage groove. This combined shock-absorbing rubber, through its combined structural design, allows for adjustment of the shock-absorbing return stroke as needed, greatly improving the shock-absorbing effect. Its detachable design facilitates the use of shock-absorbing components as needed, expanding its applicability. The varying depths of the design allow for easy storage or unfolding as required. Furthermore, the hollow shock-absorbing chamber at the bottom of the support column enhances shock absorption while ensuring anti-loosening performance, resulting in superior safety.

[0004] This combined damping rubber achieves damping solely through the insertion and connection of a single rubber body and an auxiliary support ring. Its damping structure mainly relies on the deformation of the rubber body and the hollow damping chamber inside the support column. It does not have independent elastic components to enhance the buffering effect, resulting in a single overall buffering level that is difficult to meet the multi-dimensional damping requirements under complex working conditions. Utility Model Content

[0005] The purpose of this invention is to provide a multi-cavity buffer double-layer shock absorber rubber component to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-cavity, double-layer shock absorber rubber component includes a rubber assembly. The rubber assembly includes a bottom shock-absorbing rubber pad located below and a top shock-absorbing rubber pad mounted on top of the bottom shock-absorbing rubber pad. The bottom shock-absorbing rubber pad has a through hole at its axial center, and the top shock-absorbing rubber pad has a through hole at its axial center. The through hole and the through hole are used to fix the rubber assembly to the desired position using bolts. The top surface of the bottom shock-absorbing rubber pad has a plurality of equally spaced concave cavities in an annular shape, and the bottom surface of the top shock-absorbing rubber pad has a plurality of concave holes corresponding to the positions of the concave cavities. An elastic component is provided between the concave cavities and the concave holes. The elastic component includes a spring and two base plates fixed at the top and bottom ends of the spring. The two base plates abut against the bottom of the concave cavity and the bottom of the concave hole, respectively.

[0008] Preferably, the top surface of the bottom shock-absorbing rubber pad has several grooves arranged in a ring at equal intervals around the axis of the bottom shock-absorbing rubber pad;

[0009] In this design, the groove increases the deformation space of the bottom shock-absorbing rubber pad, improving its shock absorption performance, while also facilitating its engagement with the annular groove of the top shock-absorbing rubber pad.

[0010] Preferably, a plurality of concentrically distributed annular grooves are formed on the bottom surface of the top shock-absorbing rubber pad with the axis of the top shock-absorbing rubber pad as the center. When the bottom surface of the top shock-absorbing rubber pad is in contact with and aligned with the top surface of the bottom shock-absorbing rubber pad, the annular grooves and the grooves are intersected.

[0011] In this design, the interlocking of the annular groove and the recessed groove further disperses the pressure, optimizes the stress state of the rubber component, and enhances the shock absorption effect.

[0012] Preferably, the top surface of the bottom shock-absorbing rubber pad has a plurality of upwardly protruding hanging posts arranged in a ring at equal intervals around the axis of the bottom shock-absorbing rubber pad. The top of the hanging posts is mushroom-shaped. The bottom surface of the top shock-absorbing rubber pad has a plurality of hanging holes corresponding to the positions of the hanging posts. The internal shape of the hanging holes is adapted to the shape of the hanging posts. When the hanging post is inserted into the hanging hole, the hanging post is hooked into the hanging hole.

[0013] In this design, the combination of the hanging post and the hanging hole enables precise positioning and a stable connection between the top and bottom shock-absorbing rubber pads, preventing relative displacement between the two during use.

[0014] Preferably, a protrusion is provided on the end face of the base plate near the spring, the protrusion extends into the inside of the spring, and the protrusion is used to limit the spring;

[0015] In this configuration, the protruding post restricts the deformation direction of the spring, preventing it from tilting or shifting under force and ensuring the stable operation of the elastic component.

[0016] Preferably, a plurality of through holes are provided circumferentially at the bottom position of the outer surface of the bottom shock-absorbing rubber pad and at the top position of the outer surface of the top shock-absorbing rubber pad.

[0017] In this design, the through holes help to disperse the stress at the edges of the rubber pad, reduce stress concentration, and improve the structural strength and service life of the rubber assembly.

[0018] Preferably, metal end plates are bonded and fixed to both the top and bottom end faces of the rubber assembly, and a central hole is provided in the middle of the end plate to allow passage through the through hole and the via hole to be cleared.

[0019] In this configuration, the end plates allow for more even stress distribution on the rubber assembly, while also enhancing the stability and reliability of its connection to external structures.

[0020] Preferably, a protrusion is integrally formed on the end plate near the center of the end face of the rubber assembly. The protrusion has a hollow cylindrical structure. The protrusions on the two end plates extend into the through hole and the through hole, respectively. The height of the protrusion is less than the thickness of the bottom shock-absorbing rubber pad or the top shock-absorbing rubber pad.

[0021] In this configuration, the convex sleeve enhances the connection strength between the end plate and the rubber assembly, while also serving as a guide and positioning element during installation.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This multi-cavity, double-layer shock absorber rubber component incorporates an elastic element between the recessed cavity of the bottom shock-absorbing rubber pad and the recessed hole of the top shock-absorbing rubber pad. This adds the elastic buffering effect of the spring to the original elastic buffering of the rubber material itself. Through the synergistic effect of the rubber and the spring, a double buffering structure is formed, which can improve the buffering adaptability to vibrations of different forces and frequencies, enrich the damping levels, and adapt to more complex damping scenarios.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figures 1-5 The multi-cavity buffer double-layer shock absorber rubber component includes a rubber assembly 100. The rubber assembly 100 includes a bottom shock-absorbing rubber pad 110 located below and a top shock-absorbing rubber pad 120 installed on top of the bottom shock-absorbing rubber pad 110. The bottom shock-absorbing rubber pad 110 has a through hole 111 at its axial center, and the top shock-absorbing rubber pad 120 has a through hole 121 at its axial center. The through hole 111 and the through hole 121 are used to fix the rubber assembly 100 to the required position using bolts, so as to facilitate the stable installation of the rubber component on the equipment or structure that needs shock absorption, and enable the rubber assembly 100 to play a shock absorption role.

[0035] like Figures 2-5As shown, in this invention, the top surface of the bottom shock-absorbing rubber pad 110 has a plurality of annularly spaced recesses 112, and the bottom surface of the top shock-absorbing rubber pad 120 has a plurality of recesses 122 corresponding to the positions of the recesses 112. An elastic component 130 is provided between the recesses 112 and the recesses 122. The elastic component 130 includes a spring 131 and two base plates 132 fixed at the top and bottom ends of the spring 131. The two base plates 132 abut against the bottom of the recesses 112 and the bottom of the recesses 122, respectively. By providing the elastic component 130 between the recesses 112 and the recesses 122, when the rubber component 100 is subjected to pressure, the spring 131 can undergo elastic deformation, which, combined with the elasticity of the rubber pad itself, achieves multi-cavity buffering and effectively absorbs and disperses vibrations. A protrusion 1321 is provided on the end face of the base plate 132 near the spring 131. The protrusion 1321 extends into the inside of the spring 131 and serves to limit the movement of the spring 131. The protrusion 1321 can limit the displacement of the spring 131 during deformation, ensuring that the spring 131 is always in a stable working state and improving the reliability of the shock absorption structure.

[0036] like Figures 2-4 As shown, specifically, the top surface of the bottom damping rubber pad 110 has several grooves 114 arranged in a ring at equal intervals around the axis of the bottom damping rubber pad 110. The bottom surface of the top damping rubber pad 120 has several concentrically distributed annular grooves 124 arranged around the axis of the top damping rubber pad 120. When the bottom surface of the top damping rubber pad 120 is in contact with and aligned with the top surface of the bottom damping rubber pad 110, the annular grooves 124 and the grooves 114 intersect. The interlacing arrangement of the grooves 114 and the annular grooves 124 can increase the deformation path of the rubber assembly 100 when the rubber assembly 100 is under pressure, further enhancing the damping capacity of the rubber assembly 100, and at the same time, it can adapt to forces in different directions.

[0037] like Figure 3 and Figure 4 As shown, furthermore, the top surface of the bottom shock-absorbing rubber pad 110 is provided with several upwardly protruding hanging posts 113 arranged in a ring at equal intervals around the axis of the bottom shock-absorbing rubber pad 110. The top of the hanging posts 113 is mushroom-shaped. The bottom surface of the top shock-absorbing rubber pad 120 is provided with several hanging holes 123 corresponding to the positions of the hanging posts 113. The internal shape of the hanging holes 123 is adapted to the shape of the hanging posts 113. When the hanging posts 113 are inserted into the hanging holes 123, the hanging posts 113 are hooked into the hanging holes 123. The cooperation between the hanging posts 113 and the hanging holes 123 enables the top shock-absorbing rubber pad 120 and the bottom shock-absorbing rubber pad 110 to be accurately positioned and firmly connected during installation, preventing relative sliding of the two rubber pads during use and ensuring the stability of the shock-absorbing structure.

[0038] like Figures 1-4As shown, in addition, several through holes 140 are circumferentially provided at the bottom position of the outer surface of the bottom shock-absorbing rubber pad 110 and the top position of the outer surface of the top shock-absorbing rubber pad 120. The through holes 140 can cause the rubber material to deform into the holes when the rubber pad is compressed, thereby reducing the stress concentration on the surface of the rubber pad. At the same time, it is beneficial for the rubber pad to be evenly stressed in different directions, thereby improving the overall shock absorption performance and service life of the rubber assembly 100.

[0039] In this embodiment, the multi-cavity buffer double-layer shock absorber rubber component is used in the following ways: First, the rubber assembly 100 is fixed to the equipment or structure requiring shock absorption using bolts through the through hole 111 and the through hole 121. Then, when the equipment or structure vibrates, the rubber elasticity of the bottom shock-absorbing rubber pad 110 and the top shock-absorbing rubber pad 120 first absorbs part of the vibration energy. Next, the vibration is transmitted to the elastic component 130 between the cavity 112 and the hole 122, and the spring 131 undergoes elastic deformation, further buffering the vibration. Finally, the staggered structure of the groove 114 and the annular groove 124, the cooperation between the hanging column 113 and the hanging hole 123, and the setting of the through hole 140 work together to enhance the shock absorption effect, so that the rubber assembly 100 effectively reduces the vibration transmitted to the equipment or structure.

[0040] Example 2

[0041] To ensure that the rubber assembly 100 experiences more uniform stress when compressed after installation, such as Figure 1 and Figure 2 As shown, metal end plates 200 are bonded and fixed on both the top and bottom end faces of the rubber assembly 100. The end plates 200 have a central hole with a clearance hole 111 and a through hole 121 in the middle. The end plates 200 can distribute the pressure evenly on the rubber assembly 100, avoid excessive local stress, and improve the stability and durability of the rubber components.

[0042] like Figure 2 As shown, specifically, a protrusion 210 is integrally formed on the end plate 200 near the center of the end face of the rubber assembly 100. The protrusion 210 has a hollow cylindrical structure. The protrusions 210 on the two end plates 200 extend into the through hole 111 and the through hole 121, respectively. The height of the protrusion 210 is less than the thickness of the bottom shock-absorbing rubber pad 110 or the top shock-absorbing rubber pad 120. The protrusions 210 extending into the through hole 111 and the through hole 121 further enhance the connection strength between the end plate 200 and the rubber assembly 100. At the same time, when the rubber assembly 100 is under pressure, the protrusion 210 can play a certain guiding role to ensure the stability of the force direction of the rubber assembly 100.
