Description

Technical Field

[0001] The utility model belongs to the technical field of seat foam sponges, in particular to a car seat foam sponge structure with sound insulation effect. Background Art

[0002] Car seats are an important part of the car interior, providing support for the driver and passengers' bodies, including support for the back, hips, and legs to maintain a comfortable sitting posture. During driving, especially on bumpy roads or when turning, good support can help passengers stay stable and reduce body shaking.

[0003] Car seat foam is a key component that directly affects seat comfort. High-quality foam has good elasticity and resilience, and can adaptively adjust its shape according to the passenger's sitting posture and weight to relieve body pressure. Its density and hardness can be adjusted according to the needs of different car models. For example, in luxury cars, the seat sponge may be softer and denser to provide ultimate comfort; while in sports cars, the sponge may be slightly harder to provide better support for the driver during intense driving.

[0004] Currently, existing technologies have the problem that during driving, external traffic noise, such as the engine noise of other vehicles, horn sounds, tire friction with the road, and the noise of the vehicle itself, can easily enter the vehicle. If the seats are poorly soundproofed, these noises can directly affect passengers through the seats. Especially when passengers are sitting for a long time, the continuous noise interference can make people feel irritated and tired, reducing the ride comfort.

[0005] In order to solve the above problems, the present application proposes a car seat foam sponge structure with sound insulation effect. Utility Model Content

[0009] Furthermore, the bottom surface of the support mounting plate is provided with an anti-wear plate, and the anti-wear plate needs to be in a soft rubber shape.

[0010] Furthermore, two groups of fixing pins are provided above the support mounting plate, and the bottom end of each fixing pin passes through the support mounting plate and extends to the interior of the wear-resistant plate.

[0011] Furthermore, a protective sleeve is fixedly connected to the upper surface of the support mounting plate, and the protective sleeve is arranged on the outside of the foam cotton body, sound-absorbing cotton, sound-insulating cotton and sound-insulating soft board.

[0012] Furthermore, two groups of limit frames are provided above the protective cover, and the bottom surface of each limit frame passes through the protective cover, sound insulation cotton, sound absorbing cotton and foam cotton body in sequence and is fixedly connected to the upper surface of the support mounting plate.

[0013] Furthermore, a protective cushion is fixedly connected to the upper surface of the protective sleeve, and an inner wall of the protective cushion is fixedly connected to the outer surface of the limiting frame.

[0014] Furthermore, the upper surface and the bottom surface of the sound insulation soft board are fixedly connected with limit plates arranged at equal distances, and the outer surface of each limit plate is fixedly connected to the inner wall of the foam body.

[0015] The utility model has the following beneficial effects:

[0016] The utility model is provided with a support mounting plate, which can support the foam cotton body, sound-absorbing cotton and sound insulation cotton. At the same time, the foam cotton body can make the ride comfortable, and the sound insulation cotton is composed of a high-density and compact cotton body, which can block the direct penetration of sound. At the same time, the sound-absorbing cotton uses a porous material such as polyester fiber, which can cause multiple reflections and friction when the sound waves propagate in the gap, thereby absorbing the sound passing through the sound insulation cotton, and then the foam cotton body can be soundproofed.

[0017] The utility model provides a sound insulation soft board inside the foam cotton body, which can provide a certain support for the foam cotton body and enhance its stability when it is subjected to pressure or vibration. During the driving process of the vehicle, the foam cotton body inside the seat foam cotton can reduce the deformation of the foam cotton caused by vibration, and the sound insulation soft board blocks the direct penetration and transmission of sound, thereby maintaining a stable sound insulation effect.

[0018] To sum up, the sound insulation cotton can be used to block the sound and reduce the noise transmitted into the foam cotton body, and the sound-absorbing cotton can be used to absorb and reduce the sound passing through the sound insulation cotton, so that the foam cotton body can reduce the absorbed noise, and then the porous structure of the foam cotton body itself can be used to reduce the noise, and the sound insulation soft board can be used to support the foam cotton body and reduce the direct penetration of noise, so that the foam cotton body can have a good sound insulation effect.

When using the seat, the user sits on the protective cushion 4, so that the protective cushion 4 is stressed, and when the protective cushion 4 is stressed, the foam cotton body 7 and the protective cushion 4 are supported by the supporting mounting plate 1 and the sound insulation soft plate 10, and the noise generated by vibration is reduced by the support. At the same time, the noise reaches the sound insulation cotton 9 through the protective cushion 4 and the protective cover 3, and the sound insulation cotton 9 itself The compact and high-density material blocks noise and improves the effect of noise isolation. When a small amount of noise enters the sound insulation cotton 9, it passes through the sound-absorbing cotton 8 and the large number of interconnected pores inside. When the sound is transmitted, the pores cause the sound waves to reflect and rub multiple times in it, thereby converting the sound energy into heat energy and effectively absorbing medium and high frequency sounds. When a small amount of noise is transmitted into the foam cotton body 7, the holes in the foam cotton body 7 itself cause the noise to be reflected and rubbed multiple times again, and the noise in the foam cotton body 7 is isolated and blocked by the sound insulation soft board 10, so that the foam cotton body 7 of the car seat has a sound insulation effect when in use.
