They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0016] Below is a combination of the embodiments and the attached Figure 1 , the technical solution of the utility model is further elaborated.

[0017] Example 1

[0018] A shock-absorbing and damping gasket comprises, from inside to outside, a metal support layer 1, a high elastic material energy-absorbing layer 2, a damping layer 3 and a protective layer 4, the metal support layer 1 comprises an upper metal sheet 11 and a lower metal sheet 12, the upper metal sheet 11 and the lower metal sheet 12 are connected by a magnetic attraction layer 13, protrusions 14 are arranged on the end surfaces of the upper metal sheet 11 and the lower metal sheet 12, the elastic material energy-absorbing layer 2 is provided with a friction hole 21 whose inner diameter is larger than the protrusion 14, and the protrusion 14 is located outside the friction hole 21.

[0019] like Figure 1 As shown, the working principle of the utility model is: through the cooperation of the multi-layer structure of the high-elastic material energy-absorbing layer 2, the damping layer 3 and the protective layer 4, the high-elastic material energy-absorbing layer 2 serves as the internal core layer to provide the main elasticity and energy absorption, and the damping layer is distributed around the core layer to increase the damping effect; the protective layer covers the outermost layer to provide wear resistance and protection; the innermost metal support layer connects the upper and lower layers to achieve the bidirectional shock-absorbing and damping effect of the gasket, and at the same time the metal support layer 1 increases the overall structural strength, and is convenient for connection and installation through magnetic connection, and can withstand complex loads, thereby improving the applicability and reliability of the gasket.

[0020] The friction holes 21 of the elastic material energy-absorbing layer 2 are arranged in coordination with the protrusions 14 to realize the positioning and installation of the elastic material energy-absorbing layer 2. When the elastic material energy-absorbing layer 2 is deformed during the shock absorption process, friction occurs between the elastic material energy-absorbing layer 2 and the protrusions 14, thereby consuming more energy when the material is deformed, thereby improving the damping effect.

[0021] As a further preferred embodiment, the lower surface of the upper metal sheet 11 is provided with a positioning protrusion 111 passing through the magnetic attraction layer 13, and the upper surface of the lower metal sheet 12 is provided with a positioning groove 121 passing through the magnetic attraction layer 13, and the positioning protrusion 111 is arranged inside the positioning groove 121. The positioning protrusion 111 and the positioning groove 121 are matched by magnetic connection to achieve precise positioning between the upper metal sheet 11 and the lower metal sheet 12, ensuring accurate alignment of the components during assembly, and the matching of the protrusion and the groove can prevent relative sliding or loosening between the metal sheets, thereby maintaining the structural stability of the gasket.

[0022] As a further preferred embodiment, the material of the high elastic material energy absorption layer 2 is natural rubber or synthetic rubber to provide good elasticity and energy absorption capacity; the material of the damping layer 3 is PVC or polyester to generate more friction inside the material, thereby consuming more energy when the material is deformed. By increasing the internal friction, the viscoelastic material can more effectively convert vibration energy into heat energy, thereby improving the overall damping effect; the material of the protective layer 4 is polyurethane or silicone to protect the gasket surface and extend the service life.

[0023] As a further preferred embodiment, an adhesive layer 15 is provided on the surface of the upper metal sheet 11 and the lower metal sheet 12, the protrusion 14 is arranged through the adhesive layer 15, the high elastic material energy absorption layer 2 is bonded to the adhesive layer 15, the damping layer 3 is connected to the outside of the high elastic material energy absorption layer 2 by hot melt bonding, and the protective layer 4 is connected to the outside of the damping layer 3 by hot melt bonding.

[0024] As a further preferred embodiment, the magnetic attraction layer 13 is made of a permanent magnetic material. The magnetic attraction layer 13 made of a permanent magnetic material can provide a stable connection force.

[0025] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
