[0030] The preferred embodiments of the present application will be described below in detail with reference to the accompanying drawings.

[0031] As shown in Figure 1 , the automobile seat according to the present application comprises a seat frame 1, a slide rail 6 and a seat damping member. The seat frame 1 is used for supporting the hip of a passenger and is fixedly installed on the slide rail 6 through the seat damping member. The seat damping member penetrates through the seat frame 1 and the slide rail 6 to provide a vibration suppression function, effectively reducing the shaking of the seat frame 1, thereby improving the comfort of the automobile seat. When the vehicle is running on a bumpy road, the seat damping member can significantly weaken the vibration transmitted to the seat frame 1, reduce the discomfort of the passenger and avoid the dizziness phenomenon caused by the vibration.

[0032] Embodiment 1

[0033] As shown in Figures 2 to 5 ​​​​​​​​​As shown, the seat frame 1 comprises a mounting bracket (i.e. sheet metal part) 1-1 with a through hole 1-0, and the seat damping member comprises a nut 2, a first washer 3, a damping member 4, a metal sleeve 5 and a bolt 7. The damping member 4 comprises a first damping part 41, a second damping part 42 and a third damping part 43, wherein the first damping part 41 and the second damping part 42 are integrally formed, and the third damping part 43 is independently mounted on the first washer 3. The metal sleeve 5 is inserted into the through hole 1-0 for installation, the bolt 7 passes through the slide rail 6, the metal sleeve 5 and the first washer 3, and the metal sleeve 5, the damping member 4 and the first washer 3 are locked and fixed by the nut 2. In this way, the stress path of the utility model is direct conduction between the metals, which has a more optimal stress effect compared to the prior art in which the damping member 4 is arranged on the conduction path.

[0034] In the utility model, the metal sleeve 5 is designed as an annular component with a through hole in the center for the smooth passage of the bolt 7. Specifically, the metal sleeve 5 comprises an annular wall and a lower flange extending radially outward from the lower end of the annular wall, the lower flange is supported on the top surface of the slide rail 6, and the annular wall passes through the through hole 1-0 to support the first washer 3 located above the through hole 1-0. In the installed state, the annular wall of the metal sleeve 5 maintains a certain radial spacing with the bolt 7 passing through its interior to ensure the free rotation of the bolt and reduce friction, while ensuring a larger assembly tolerance through the larger gap to meet the multi-assembly point tolerance requirements of the large-opening seat frame.

[0035] In the utility model, the first damping part 41 is sleeved outside the annular wall of the metal sleeve 5 so that the inner and outer sides of the first damping part 41 are respectively attached to the outer peripheral surface of the annular wall and the inner wall of the through hole 1-0 to achieve effective damping and stable support.

[0036] In this embodiment, the first damping part 41 is interference-fitted with the through hole 1-0 on the mounting bracket 1-1 for easy assembly. To prevent the first damping part 41 from coming out of the through hole 1-0, the top of the first damping part 41 is specially designed with at least two circumferentially uniformly arranged lugs 5-0, as shown in Figure 4 These lugs 5-0 can be lapped with the upper surface of the mounting bracket 1-1 after the first damping part 41 is inserted into the through hole 1-0 to prevent the first damping part 41 from falling out of the through hole 1-0 during assembly.

[0037] In the utility model, the second damping part 42 is arranged between the lower flange of the metal sleeve 5 and the mounting bracket 1-1 so that the upper and lower sides of the second damping part 42 are respectively attached to the lower surface of the mounting bracket 1-1 and the upper surface of the lower flange of the metal sleeve 5, further ensuring the close fit and stability of the structure.

[0038] In the present embodiment, the second damping portion 42 extends radially outward from the lower end of the first damping portion 41 so as to be integrally formed with the first damping portion 41 and the second damping portion 42. In one variant of the present embodiment, the second damping portion 42 is independently mounted on the lower flange of the metal sleeve 5.

[0039] In the present utility model, the third damping portion 43 is arranged between the first gasket 3 and the mounting bracket 1-1, and the upper surface of the third damping portion 43 is attached to the lower surface of the first gasket 3.

[0040] In the present embodiment, the third damping portion 43 is mounted on the first gasket 3 through its extension portion 43-1. That is, the third damping portion 43 and its extension portion 43-1 form a ring structure to wrap the first gasket 3, ensuring a close fit between the third damping portion 43 and the first gasket 3. In another variant of the present embodiment, the extension portion 43-1 is omitted, and the third damping portion 43 is in a sheet structure. The third damping portion 43 can also be connected to the first gasket 3 by adhesion. The upper and lower surfaces of the third damping portion 43 are respectively attached to the lower surface of the first gasket 3 and the upper surface of the mounting bracket 1-1. In yet another variant of the present embodiment, a gap is formed between the lower surface of the third damping portion 43 and the upper surface of the mounting bracket 1-1. In yet another variant of the present embodiment, the third damping portion 43 is integrally formed with the first damping portion 41 and extends radially outward from the upper end of the first damping portion 41.

[0041] In the present embodiment, the top surface of the first damping portion 41 can be kept attached to the lower surface of the first gasket 3. In one variant of the present embodiment, the top surface of the first damping portion 41 can also be kept spaced apart from the lower surface of the first gasket 3. In yet another variant of the present embodiment, the third damping portion 43 is omitted, and the top surface of the first damping portion 41 is attached to the lower surface of the first gasket 3, so that the first damping portion 41 assumes the function of the third damping portion 43.

[0042] As shown in Figures 2 to 3 , the seat damping member further comprises a second gasket 8 arranged between the mounting bracket 1-1 and the third damping portion 43 to compensate for the gap between the first gasket 3 and the mounting bracket 1-1. In the case where the mounting bracket 1-1 has sufficient thickness, the second gasket 8 can be omitted.

[0043] Embodiment 2

[0044] Unlike the embodiment 1, the first damping portion 41, the second damping portion 42 and the third damping portion 43 are integrally formed to form the damping member 4, as shown in Figures 6-7 .

[0045] As shown in Figure 8As shown, the third damping part 43 of the damping member 4 is designed with multiple slits. The design of these slits allows the third damping part 43 to be set to extend upwardly obliquely before the damping member 4 is installed into the mounting bracket 1-1, thereby facilitating its smooth passage through the through-hole 1-0. After the damping member 4 is installed into the mounting bracket 1-1, the first gasket 3 exerts pressure from above, and the slits facilitate the third damping part 43 to be flattened, so that the upper and lower sides of the third damping part 43 respectively adhere to the lower surface of the first gasket 3 and the upper surface of the mounting bracket 1-1. This unique slit design not only simplifies the installation process of the damping member 4, but also enables the third damping part 43 to function similarly to the lug 5-0 of Embodiment 1, effectively preventing the damping member 4 from being dislodged from the through-hole 1-0 during installation, improving the reliability of installation and the stability of the damping member, and ensuring the overall performance of the seat damping member.

[0046] In the present utility model, the through-hole 1-0 is designed with a press hole bright band. The press hole bright band refers to a smooth area formed around the hole of a stamped part. This smooth area is achieved through a carefully designed stamping die and a precisely controlled stamping process, with the purpose of ensuring that the hole edge has no burrs or cracks, thereby improving the quality of the hole. The extension length of the press hole bright band of the through-hole 1-0 is preferably greater than 70%, reducing the friction coefficient between the damping member 4 and the mounting bracket 1-1. By reducing friction, not only can the convenience of installation and removal of the damping member be improved, but also wear caused by friction can be reduced, thereby prolonging the service life of the seat damping member.

[0047] In the present utility model, the annular wall of the damping member 4 is designed to include a plurality of radially outwardly locally thickened reinforcing ribs. Preferably, the number of these reinforcing ribs is set to be between 10 and 20, and the outer surface of each reinforcing rib is designed to be arc-shaped and outwardly convex. This design not only increases the contact area between the damping member 4 and the through-hole 1-0, thereby improving the stability of installation and the damping effect, but also enhances the structural strength of the second damping member itself. The provision of reinforcing ribs helps to more evenly distribute pressure when subjected to external forces, reducing the risk of damage caused by local stress concentration. In addition, by optimizing the number and distribution of reinforcing ribs, significant improvement in the performance of the damping member can be achieved without significantly increasing the cost of materials. This design not only improves the structural strength, but also ensures the lightweight of the damping member, achieving a balance between cost-effectiveness and performance.

[0048] In the utility model, the damping component 4 is preferably made of high-elasticity materials such as EPDM (ethylene propylene diene rubber), NR (natural rubber), and VMQ (silicone). These materials are very suitable for manufacturing damping parts due to their excellent elasticity and durability. In order to further improve the hardness and toughness of the product, the content of carbon black in the material is preferably adjusted by increasing the amount. The addition of carbon black not only improves the mechanical properties of the material, but also improves its aging resistance and wear resistance. By precisely controlling the amount of carbon black added, the overall performance and service life of the damping part can be improved while ensuring the required elasticity.

[0049] In the utility model, with reference to Figure 3a , the perforation 1-0 on the mounting bracket 1-1 is defined with a diameter d and a thickness t. With reference to Figure 5a , the third damping part 43 is in contact with the mounting bracket 1-1 and has a first contact width L1. With reference to Figure 4a , the first damping part 41 has an outer diameter D, and the second damping part 42 extends upward to form a protrusion defined with a height H. The top surface of the protrusion is in contact with the mounting bracket 1-1 and has a second contact width L2. In order to optimize the contact area and improve the compression limit displacement, the outer diameter D, the contact width L1 / L2, and the height H are matched with the diameter d and the thickness t of the perforation 1-0. This design not only improves the impact energy absorption capacity of the damping part, but also enhances its durability.

[0050] In summary, the utility model can significantly improve the shaking and abnormal noise problems of the seat through the damping component, greatly improving the comfort of riding. Compared with the prior art, the damping component of the utility model has fewer parts while ensuring sufficient strength and function, thereby saving costs and improving the competitiveness of the product. The utility model adopts a lightweight module design, which not only reduces the overall weight of the seat, but also improves the stability and durability of the structure. The design of the utility model has good universality and expandability, and can be easily installed in various seat systems with similar mounting structures. This universality means that the damping component of the utility model is not only suitable for specific seat models, but can also be widely used in seats produced by different manufacturers, as long as these seats have compatible mounting interfaces and similar functional requirements.

[0051] The above is only a preferred embodiment of the utility model, not to limit the scope of the utility model, the above embodiment of the utility model can also make various changes. That is, any simple, equivalent changes and modifications made according to the content of the claims and description of the utility model application fall within the scope of protection of the claims of the utility model patent. The utility model is not described in detail.
