[0001] The utility model relates to the technical field of automobile seats, in particular to a noise reduction structure for a side guard plate of an automobile seat. Background Art

[0002] In order to improve the driving experience, car seats are now mostly covered with leather materials. Leather materials have a better touch, but leather materials will produce a sharp sound when friction occurs, causing discomfort to the driver.

[0003] The friction of the leather material on the surface of the car seat mainly occurs when the driver sits on the seat. The shape of the seat changes and rubs against the side guard plate of the car seat. The existing method to deal with the noise generated by this friction is to improve the surface smoothness of the side guard plate, reduce friction, and thus reduce the size of the noise. However, it is still impossible to suppress the generation of noise. Noise will still be generated during each use, and the noise reduction effect is limited. Utility Model Content

[0004] The purpose of the utility model is to provide a noise reduction structure for a car seat cover side guard plate, which can utilize a contact layer to provide a larger friction force to suppress the friction movement between the car seat and the silent layer, thereby suppressing the generation of friction noise; at the same time, when noise is generated, the silent layer will absorb the noise and reduce the volume of the noise, thereby achieving a better noise reduction effect.

[0027] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined. In addition, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Combination Figures 1 to 5As shown, the utility model provides a noise reduction structure for a car seat cover side guard plate, which includes a quiet layer 1 and a contact layer 2.

[0031] Combination Figures 1 to 5 As shown, the sound-proof layer 1 is attached to the side of the side guard plate close to the car seat, and a sound-proof structure is provided inside the sound-proof layer 1; the contact layer 2 includes contact points 21, and the contact points 21 are distributed on the outer surface of the sound-proof layer 1; the contact layer 2 suppresses the friction movement between the car seat and the sound-proof layer 1 through friction force.

[0032] In this embodiment, the frictional movement between the car seat and the silent layer 1 is suppressed by the friction force between the contact layer 2 and the car seat, thereby suppressing the generation of friction noise. When the driver's movement amplitude is too large, friction noise will still be generated. At this time, the design of the contact point 21 reduces the area of ​​friction of the contact layer 1, and the friction noise is controlled within a smaller range. The friction noise is then adsorbed by the silent layer 1, and the volume of the friction noise is reduced, ultimately achieving a better noise reduction effect.

[0033] In this embodiment, the silent layer 1 replaces the side guard plate and rubs against the car seat. Since the silent layer 1 is designed with a silent structure, the noise generated can be reduced. At the same time, the contact layer 2 is designed to increase the friction between the car seat and the silent layer 1, and the friction is used to suppress the friction between the car seat and the silent layer 1. The design of the contact point 21 ensures that the friction noise is mainly generated by the friction between the car seat and the silent layer 1, and at the same time, the friction generated by the evenly distributed contact points 21 is used to suppress the friction between the car seat and the silent layer 1, thereby reducing the noise from the source.

[0034] In some embodiments, in combination Figure 3 As shown, the silent structure includes a silent plate 11, the silent plate 11 is fixedly connected to the side guard plate, echo holes are distributed on the silent plate 11, a plurality of sound wave rebound planes are arranged in the echo holes, the contact point 21 is fixedly connected to the silent plate 11, the silent plate 11 utilizes its own shape to design the echo holes to absorb noise, and at the same time, the silent plate 11 replaces the side guard plate and the car seat for friction, and then utilizes its own ability to absorb noise to achieve noise reduction.

[0035] In some embodiments, in combination Figure 4 As shown, the sound-absorbing structure includes a sound-absorbing fabric 12, and the sound-absorbing fabric 12 is fixedly connected to the side guard plate. The sound-absorbing fabric 12 is a soft and porous structure. The sound-absorbing fabric 12 utilizes the structural characteristics of its own material to absorb noise, and can also replace the friction between the side guard plate and the car seat. At the same time, the effect of the sound-absorbing fabric 12 is independent of its appearance. The surface of the sound-absorbing fabric 12 is smoother, which is conducive to reducing friction, reducing the volume of friction noise, and can also be aesthetically pleasing.

[0036] In some embodiments, the sound-absorbing fabric 12 is a textile, which is woven by warp and weft threads. Due to the production process, the internal structure of the finished textile product has the characteristics of being soft and porous, and has good performance in absorbing noise.

[0037] In some embodiments, the sound-absorbing fabric 12 is sound-absorbing cotton. The sound-absorbing cotton material has a soft and porous internal structure, which can be used to absorb noise due to the material's own characteristics.

[0038] In some embodiments, in combination Figure 4 As shown, the contact point 21 passes through the sound-absorbing fabric 12, one end of the contact point 21 is fixedly connected to the side guard plate, and the other end of the contact point 21 is abutted against the car seat. The soft porous structure inside the sound-absorbing fabric 12 makes it exhibit the characteristic of insufficient rigidity. When the contact point 21 is fixed on the sound-absorbing fabric 12, it not only fails to provide a good fixing effect for the contact point 21, but may also cause damage to the sound-absorbing fabric 12. Therefore, the contact point 21 is designed to pass through the sound-absorbing fabric 12 and be fixedly connected to the side guard plate to ensure the fixing effect of the contact point 21.

[0039] In some embodiments, in combination Figure 1 , 2 As shown, the area of ​​the contact layer 2 does not exceed the contact area between the car seat and the side guard plate, and the highest point height of the contact layer 2 does not exceed the height of the top surface of the car seat base. The design of the side guard plate will take into account the appearance, touch and other designs to improve the user experience. The contact layer 2 is difficult to be compatible with related design contents. Limiting the distribution of the contact layer 2 can protect these design contents. At the same time, the ability of the contact layer 2 to suppress noise generation through friction requires contact to produce an effect. The contact layer 2 that exceeds a specific range will lose its ability to suppress noise generation, resulting in the design of the contact layer 2 that exceeds a specific range becoming meaningless.

[0040] In some embodiments, the contact point 21 is made of rubber material, which is the most commonly used material for the contact point 21. In addition to economic benefits, the high friction coefficient and soft properties of the rubber material are highly adapted to the function of the contact point 21. The high friction coefficient can provide greater friction under the same area, and the soft property can ensure that the contact point 21 will not damage the car seat.

[0041] In some embodiments, in combination Figure 4 As shown, the contact point 21 is hemispherical. The hemispherical shape design can ensure the size of the contact surface while improving the edge smoothness, thereby reducing the damage of the contact point 21 to the car seat and increasing the service life.

[0042] In some embodiments, in combination Figure 5As shown, a sinking groove 21 is provided on the side of the side guard plate close to the car seat, and the sound-absorbing layer 1 and the contact layer 2 are both located in the sinking groove 21, and the depth of the sinking groove 21 is equal to the sum of the thicknesses of the sound-absorbing layer 1 and the contact layer 2. The design of the sinking groove 21 can embed the sound-absorbing layer 1 and the contact layer 2 into the side guard plate, thereby reducing the influence of the sound-absorbing layer 1 and the contact layer 2 on the appearance design of the side guard plate, and at the same time can eliminate the influence of the thickness of the sound-absorbing layer 1 and the contact layer 2 on the distance between the car seat and the side guard plate. The distance between the car seat and the side guard plate is one of the important design contents that affect the user experience.

[0043] Working process: When the driver sits on the car seat, the car seat is deformed by the pressure, and the deformation is transferred from the sitting position to the edge of the car seat. The edge of the car seat is against the contact layer 2. When the deformation is small, the contact layer 2 successfully suppresses the friction between the car seat and the side guard plate through friction force, fundamentally solving the friction noise.

[0044] When the deformation is large, the car seat and the side guard plate overcome the friction force and rub against each other, generating friction noise. However, the design of the contact point 21 reduces the friction area of ​​the contact layer 2, and the friction noise generated by the contact layer 2 is controlled within a smaller range. At this time, the silent layer 1 absorbs the noise through the silent structure, further reducing the volume of the noise.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
