Description

Technology Field

[0001] The present disclosure relates to a fender outer pad. Specifically, it relates to a fender outer pad provided between a fender and a fender liner. Background Technology

[0002] Generally, fender liners are attached to the car fender panels (body). Fender liners function to block vibrations and noise generated during driving from entering the vehicle's interior. Additionally, they prevent dirt, stones, water, and other foreign substances from entering the cabin, helping to extend the lifespan of the vehicle and its components. Furthermore, fender liners are equipped with thin insulators to enhance sound absorption and insulation performance.

[0003] However, conventional fender liners have a problem in that, when mounted on a fender, the sound absorption and insulation issues cannot be completely resolved by the insulator alone due to the cavity formed between the fender and the fender liner. Prior art literature

[0005] (Patent Document 0001) KR 10-2017-0038948 B1 (Published April 10, 2017) The problem to be solved

[0006] The problem that the present disclosure aims to solve is to provide a fender outer pad capable of minimizing road noise generated during vehicle operation. means of solving the problem

[0008] A fender outer pad according to an embodiment comprises: a first nonwoven fabric layer provided along the fender; a sound-absorbing layer laminated to the first nonwoven fabric layer; and a second nonwoven fabric layer laminated to the sound-absorbing layer.

[0009] In addition, the sound-absorbing layer of the fender outer pad according to the embodiment is characterized by comprising at least one of a vertical nonwoven fabric, FELT, and PU SLAB.

[0010] In addition, the first nonwoven fabric layer of the fender outer pad according to the embodiment is characterized by being made of a water-repellent nonwoven fabric. Effects of the invention

[0012] The fender outer pad according to the embodiment is provided in a cavity formed between the fender and the fender liner, and can minimize road noise and vibration caused by contact between the tire and the road surface during vehicle driving.

[0013] In addition, the fender outer pad according to the embodiment is made of a material that allows the thickness of the sound-absorbing layer to be easily changed. Accordingly, the thickness of the sound-absorbing layer can be changed according to the vehicle model, so the fender outer pad according to the embodiment can be installed in the cavity formed between the fender and the fender liner regardless of the vehicle model. Brief explanation of the drawing

[0014] Figure 1 shows a cross-section of a fender outer pad according to an embodiment. Figure 2 shows a fender with a fender outer pad installed according to an embodiment. Figure 3 shows the appearance of the fender before the fender outer pad according to the embodiment is mounted. FIG. 4 is a graph showing the decibels by frequency when a vehicle is driven at 60 KPH with the fender outer pad according to the embodiment installed. Specific details for implementing the invention

[0015] The advantages and features of the present disclosure and the methods for achieving them will become clear by referring to the embodiments described below in detail together with the accompanying drawings. However, the present disclosure is not limited to the embodiments disclosed below but may be implemented in various different forms. These embodiments are provided merely to make the present disclosure complete and to fully inform those skilled in the art of the scope of the invention, and the present disclosure is defined only by the scope of the claims. Throughout the specification, like reference numerals refer to like components.

[0017] Referring to FIG. 1, which shows a cross-section of a fender outer pad (10) [hereinafter referred to as 'fender outer pad (10)'] according to an embodiment, and FIG. 2, which shows the fender outer pad (10) mounted on a fender (F), the fender outer pad (10) is provided between the fender (F) and the fender liner and includes a first non-woven fabric layer (100), a sound-absorbing layer (200), and a second non-woven fabric layer (300). In particular, the fender outer pad (10) is located in a cavity formed between the fender (F) and the fender liner.

[0018] The first nonwoven fabric layer (100) is provided along the fender (F). Additionally, the first nonwoven fabric layer (100) may be composed of a water-repellent nonwoven fabric having the property of repelling water. As a result, it has the effect of preventing contamination or corrosion of the fender (F).

[0019] The sound-absorbing layer (200) is laminated onto the first nonwoven fabric layer (100). The sound-absorbing layer (200) may be composed of at least one of a vertical nonwoven fabric, FELT, and PU SLAB (Polyurethane Sound, Light, and Anti-vibration Material). Additionally, the sound-absorbing layer (200) may be manufactured to have various three-dimensional shapes.

[0020] Vertical nonwoven fabric is produced by stacking fibers vertically; due to its greater thickness compared to standard nonwoven fabric, it offers superior compressibility, elasticity, and durability. Consequently, it is effective in blocking noise and vibration.

[0021] FELT is a soft fabric made by compressing various fibers, and it has excellent sound absorption and shock absorption effects.

[0022] PU SLAB is a polyurethane-based sound-absorbing and vibration-damping material that is effective in reducing noise and minimizing vibration inside a vehicle.

[0023] In addition, the sound-absorbing layer (200) can have various 3D shapes by changing the thickness according to the vehicle type.

[0024] The second nonwoven layer (300) is laminated onto the sound-absorbing layer (200). The second nonwoven layer (300) may be composed of a breathable ordinary nonwoven fabric. This prevents water from accumulating inside the fender outer pad (10).

[0026] FIG. 3 shows the appearance of the fender (F) before the fender outer pad (10) is mounted, and FIG. 2 shows the appearance of the fender (F) with the fender outer pad (10) mounted.

[0027] Before installing the fender outer pad (10), the thickness of the sound-absorbing layer (20) is adjusted according to the vehicle model, and then the fender outer pad (10) is installed on the fender (F) as shown in FIG. 2. Afterwards, the fender liner is installed.

[0029] Referring to FIG. 5, which is a graph showing decibels by frequency when the vehicle is driven at 60 KPH with the fender outer pad (10) installed, the solid line represents the decibels by frequency before installing the fender outer pad (10), and the dotted line represents the decibels by frequency after installing the fender outer pad (10).

[0030] When the vehicle is driven at 60 KPH with the fender outer pad (10) installed, it can be seen that the noise level is reduced by 1.3 dB in the 250 to 500 Hz range.

[0032] The expressions (terms, visualized images, etc.) used in describing the embodiments of the present disclosure are merely selected for instrumental purposes to enhance understanding of the technology.

[0033] Furthermore, due to circumstances, the present disclosure has been described by a limited number of embodiments, and a person skilled in the art will be able to come up with new embodiments based on the described embodiments without departing from the technical spirit of the present disclosure.

[0034] Accordingly, the claims of the present disclosure should not be limited by some expressions appearing in the ‘description of the invention’ and ‘drawings,’ but should be broadly interpreted based on the fundamental technical concept inherent throughout the specification.
