Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction and noise reduction technology, specifically relating to a novel high-elasticity rubber vibration damping pad structure. Background Technology

[0002] The background technology of vibration damping pads can be traced back to the early 20th century. With the development of industrialization and transportation, people's demand for vibration control and noise reduction has been increasing. In the early days, materials such as rubber and cork were used as damping media. In the course of development, after the mid-20th century, breakthroughs in polymer materials and composite materials technology promoted the improvement of vibration damping pad performance. For example, the application of elastic materials such as polyurethane and silicone has made them both durable and adaptable. Today, vibration damping pads are widely used in construction, automobiles, electronic equipment, rail transportation and home furnishings, becoming a key component for vibration control and noise management.

[0003] In existing technologies, traditional damping pads generally suffer from problems such as insufficient elastic recovery force, easy plastic deformation after long-term compression, and low energy absorption efficiency under high-frequency vibration. In particular, damping pads with single material structures often cannot take into account both stiffness and damping characteristics, resulting in a sharp decline in damping performance under complex working conditions.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example

[0025] Reference Figures 1-4 This is an embodiment of the present invention, which provides a novel high-elasticity rubber shock-absorbing pad structure, comprising:

[0026] Mounting plate 101, mounting hole 102 formed on the side wall of mounting plate 101, base 103 fixedly connected to the side wall of mounting plate 101, air chamber 104 disposed on the side wall of base 103, connecting component 105 disposed on the side wall of base 103, and shock-absorbing component 106 disposed in the inner cavity of connecting component 105.

[0027] Specifically, the connecting component 105 includes a housing 105a movably connected to the side wall of the base 103, and a reserved hole 105b provided on the side wall of the housing 105a. The connecting component 105 also includes a connecting plate 105c fixedly connected to the inner wall of the housing 105a, and a threaded pipe 105d communicating with the side wall of the connecting plate 105c.

[0028] Furthermore, the housing 105a serves as the protective shell of the shock absorber 106, allowing limited displacement between the housing 105a and the shock absorber 106 to provide a buffer space for shock absorption. The reserved holes 105b on the side wall are used to balance the air pressure inside and outside the air chamber 104 to avoid negative pressure affecting elastic deformation.

[0029] Preferably, the damping component 106 includes a dispersion layer 106a fixedly connected to the side wall of the connecting plate 105c, and an absorption layer 106b disposed on the surface of the dispersion layer 106a. The damping component 106 also includes a filling layer 106c fixedly connected to the surface of the absorption layer 106b, and a support layer 106d fixedly connected to the surface of the filling layer 106c.

[0030] It should be noted that the dispersion layer 106a is made of rubber material and has dense pores inside. The absorption layer 106b is made of polyethylene granules. The filling layer 106c is made of honeycomb aluminum material. The support layer 106d is made of highly elastic rubber material.

[0031] In use, when external vibrations are transmitted to the mounting plate 101, the vibration energy is transmitted through the base 103 to the air chamber 104 and the connecting component 105. The sleeve 105a generates limited displacement on the side wall of the base 103 to provide initial buffering. At the same time, the air pressure in the air chamber 104 achieves dynamic balance through the reserved hole 105b. In the damping component 106, the dispersion layer 106a disperses the vibration energy in multiple directions through internal small holes. The polyethylene particles of the absorption layer 106b consume part of the energy through inter-particle friction. The honeycomb aluminum filling layer 106c of the filling layer 106c further absorbs and disperses the vibration. Finally, the high elasticity rubber material of the support layer 106d provides the final elastic support and converts the residual vibration energy into elastic potential energy for release, thereby achieving a multi-level damping effect.

[0032] In summary, the air pressure is dynamically adjusted through the cooperation of the air chamber 104 and the reserved hole 105b, effectively avoiding negative pressure interference. At the same time, the multi-layer composite vibration reduction structure utilizes the small hole structure of the dispersion layer 106a to evenly disperse vibration energy. Combined with the particle friction energy dissipation mechanism of the absorption layer 106b and the honeycomb aluminum energy absorption characteristics of the filling layer 106c, the vibration attenuation efficiency is greatly improved. Finally, the high elastic support layer 106d provides stable rebound support. The overall structure has excellent buffering performance and durability, and can be widely used in machinery, vehicles, construction and other fields to effectively reduce vibration and noise and extend the service life of equipment.
