[0002] With the popularization of electric vehicles, pure electric vehicles do not have the masking effect of engine noise, and the road noise problem is more prominent. The road noise problem of models on the market ranks high in the IQS (Initial Quality Survey), and user complaints are relatively strong. Especially for sedans, in order to meet attributes such as drivability, harder tires will be used, inevitably sacrificing some comfort performance. The tire noise radiates to the entire rear quarter panel through the rear quarter panel sheet metal, and then is transmitted into the vehicle, affecting the overall vehicle comfort.

[0003] As Figure 1 shown, the dotted line in the figure is the propagation path of noise in the vehicle. The main path for road noise to reach the human ear when the vehicle is driving is: tire 4 → outer wheelhouse 5 → cavity formed by the rear quarter panel sheet metal and the side trim panel 7 of the vehicle body sheet metal 3 → gap between the trim panel body 1 and the triangular window 2 → vehicle headrest 6 (at the human ear).

[0004] Currently, there are some corresponding improvements on the market for related problems. For example, expansion blocks are added to the body cavity outside the C-pillar to block the path of tire noise transmission, or L-shaped sound-absorbing cotton is filled in the rear quarter cavity through interference fit to achieve the suppression of road noise at the vehicle headrest 6 (at the human ear of the rear seat).

[0005] These methods can alleviate the current noise problem in the rear quarter of the vehicle, but these methods are complex in process, significantly increase the cost, and require higher requirements for production line assembly. Summary of the Utility Model

[0041] Terms such as "first", "second", "third", etc. are only used to distinguish elements with similar attributes, rather than indicating or implying relative importance or a specific order.

[0042] The term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion. In addition to the listed elements, it may also include other elements not specifically listed.

[0043] As Figure 2 and Figure 3 shown, this embodiment provides a sound-insulating triangular window trim, which includes a trim body 1. An opening 11 is provided on the trim body 1. When the trim body 1 is installed, the opening 11 is aligned with the triangular window, achieving a light-transmitting effect. A flange 12 extends from the periphery of the opening 11 on the trim body 1 towards the interior of the vehicle, and a sound-insulating member 13 is sleeved on the flange 12.

[0044] The sound-insulating triangular window trim provided in this embodiment is installed on the side of the triangular window 2 inside the vehicle. During installation, the opening 11 of the trim body 1 is aligned with the triangular window 2, and the light at the triangular window 2 is transmitted into the vehicle through the opening 11. The trim body 1 is installed on the vehicle sheet metal 3 parallel to the triangular window 2. At this time, the sound-insulating member 13 on the flange 12 of the trim body 1 abuts against the vehicle sheet metal 3, and the vehicle sheet metal 3 abuts against the sound-insulating member 13 so that there is no gap between the vehicle sheet metal 3 and the trim body 1. As Figure 1 shown in, the gap between the trim body 1 and the triangular window 2 leading to the vehicle headrest 6 is filled, so that the noise is converted from air transmission to transmission by the sound-insulating member 13 at this point. When the noise propagates in the sound-insulating member 13, the sound waves are greatly absorbed, so that the propagation of the noise is blocked by the sound-insulating member 13 at the interval between the triangular window 2 and the trim body 1, achieving the purpose of reducing the noise inside the vehicle and improving the riding comfort of passengers.

[0045] Specifically, the sound-insulating member 13 can be a foam, or a sound-absorbing foam or a sound-absorbing object made of pure cotton material, etc.

[0046] In this embodiment, the foam is bonded to the flange 12 of the trim body 1 by glue. Using foam has a low cost, and the production by bonding is simple without complex processes. When mass-producing the trim, the foam can be bonded to the trim body 1, and then the trim body 1 with the bonded foam can be transported to the next process in batches, with high production efficiency.

[0047] As Figure 4 shown, a plurality of buckles 14 for connecting with the vehicle sheet metal are provided on the trim body 1. The connection by the buckles 14 can be convenient and fast when installing the trim body 1, and can be quickly disassembled when replacement and maintenance are required.

[0048] Please further refer to Figure 5 , further, an installation portion 15 extending above the sound-insulating member 13 is provided on the trim body 1. The installation portion 15 includes an extension seat 151 and an installation plate 152. The extension seat 151 is provided above the opening 11, and its extending direction is perpendicular to the axis of the opening 11 of the trim body 1. The installation plate 152 is provided on the side of the extension seat 151 close to the opening 11 and is perpendicular to the extension seat 151, so that the installation plate 152 is located above the sound-insulating member 13. The buckle 14 is located on the installation plate 152 of the installation portion 15. When the trim body 1 is installed on the vehicle sheet metal, the side of the trim body 1 with the sound-insulating member 13 faces the triangular window. The buckle 14 is installed directly above the sound-insulating member 13 through the installation portion 15. Through the buckle 14 above the sound-insulating member 13 and the buckle of the triangular frame, the trim body 1 can be closer to the triangular window, reducing the distance between the trim body 1 and the triangular window, so as to better achieve the effect of blocking the propagation of noise.

[0049] Specifically, as Figure 5As shown, the buckle 14 includes a first inclined surface 141 and a second inclined surface 143. The second inclined surface 143 is closer to the triangular window than the first inclined surface 141. One end of the first inclined surface 141 is connected to the mounting portion 15, and the other end of the first inclined surface 141 is connected to one end of the second inclined surface 143. One end of the second inclined surface 143 is connected to the first inclined surface 141, and the other side of the second inclined surface 143 is connected to the mounting portion 15. This makes the first inclined surface 141 and the second inclined surface 143 distributed in a triangle, and the angle between the first inclined surface 141 and the second inclined surface 142 is greater than 90° and less than 180°. When installing the trim body 1 on the automotive sheet metal, the buckle 14 of the trim body 1 is pushed outward towards the automotive sheet metal. A corresponding slot is provided on the automotive sheet metal. The second inclined surface 143 of the buckle 14 of the trim body 1 presses the automotive sheet metal around the slot and gradually moves into the slot of the automotive sheet metal. When the highest point of the second inclined surface 143 slides into the slot, one side wall of the slot abuts against the first inclined surface 141 of the buckle 14, thereby realizing the connection between the trim body 1 and the automotive sheet metal. When disassembling the trim body 1 from the automotive sheet metal, the trim body 1 is pulled inward in the opposite direction of installing the trim body 1. The first inclined surface 141 of the trim body 1 gradually slides out of the slot of the automotive sheet metal. When the highest point of the first inclined surface 141 slides out of the slot of the automotive sheet metal, the trim body 1 can be removed. Preferably, the connection 142 between the first inclined surface 141 and the second inclined surface 143 is a smooth curved surface, which facilitates the installation and disassembly of the trim body 1.

[0050] In summary, the sound-insulating triangular window trim provided in this embodiment has the advantages of good sound insulation effect, low production cost, and simple structure, and is also convenient for installation and disassembly.

[0051] As Figures 6 to 10 As shown, this embodiment also provides a triangular window installation structure, including a triangular window 2, an automotive sheet metal 3, and the sound-insulating triangular window trim as described above. An installation slot for installing the triangular window 2 is provided on the automotive sheet metal 3, and the triangular window 2 is installed in the installation slot. The trim body 1 is installed on the automotive sheet metal 3, and the surface of the trim body 1 where the sound-insulating member 13 is installed is aligned with the triangular window 2. A butting portion 31 is provided on the automotive sheet metal 3 along the periphery of the sound-insulating member 13. When installing the trim body 1, the butting portion 31 of the automotive sheet metal 3 abuts against the sound-insulating member 13, and the sound-insulating member 13 is clamped between a plurality of butting portions 31.

[0052] That is, as described above, the trim panel body 1 is installed on the vehicle sheet metal 3. In the figure, the vehicle sheet metal 3 is marked at one place. However, it should be understood that the vehicle sheet metal 3 mentioned in this article generally refers to the vehicle sheet metal around the triangular window 2, and it can be composed of multiple vehicle sheet metals. These vehicle sheet metals 3 all have abutting portions 31, and these abutting portions 31 enclose to block the gap between the trim panel body 1 and the vehicle sheet metal 3 along the periphery of the sound insulation member 13, thereby blocking the noise propagation path. The vehicle sheet metal 3 abuts against the sound insulation member 13 of the trim panel body 1 through the abutting portion 31, thereby blocking the noise propagation path and making the interior noise of the vehicle small.

[0053] Preferably, the sound insulation member is deformable. For example, the material of the foam is soft and can be deformed. The abutting portion 31 can be inserted into the sound insulation member 13, and the insertion depth is 3 mm to 4 mm. This can make the connection between the abutting portion 31 and the sound insulation member 13 tight, and has the advantage of sound insulation effect.

[0054] As Figure 11 shown, Figure 11 It is a comparison chart of noise data before and after installing the triangular window installation structure provided in this embodiment. The sound level curve located entirely below in the figure is the sound level curve collected after applying the structure provided in this embodiment. It can be seen from the figure that after installing the triangular window installation structure provided in this embodiment, the interior noise of the vehicle has decreased.

[0055] This embodiment also provides a vehicle, including the triangular window installation structure as described above.

[0056] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
