[0032] The sound insulating member 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0033] Reference Figure 1-Figure 4 As shown, the sound insulation element 100 according to the embodiment of the present invention may include: a sound insulation body 10 .

[0034] Specifically, the sound insulation body 10 is provided with a mounting hole, through which the assembly requirements of the vehicle can be achieved, and the sound insulation component 100 is arranged in the vehicle, which can reduce the propagation and interference of various noises when the vehicle is driving, improve the interior environment of the vehicle, and enhance driving comfort.

[0035] In addition, if Figure 1-Figure 4 As shown, the sound insulation member 100 further includes a virtual cut hole 20, which is removably disposed in the mounting hole, and an operation entrance 21 is disposed on the virtual cut hole 20. The operation entrance 21 is disposed in the thickness direction (eg Figure 3 ) passes through the virtual cut hole 20 in the up and down directions shown in . Therefore, when the final assembly process needs to use the mounting hole, the production personnel's fingers or operating tools can be inserted into the operating entrance 21 to pull out the virtual cut hole 20, so as to achieve quick removal, facilitate the mounting hole to achieve the required assembly requirements, and avoid directly pushing the virtual cut hole 20 so that the hole wall of the mounting hole causes scratches to the production personnel, effectively reducing the harm to the production personnel and ensuring the stability of the production rhythm. At the same time, when the mounting hole is not needed, there is no need to remove the virtual cut hole 20, which can avoid weakening the sound insulation performance of the sound insulation component 100, thereby avoiding affecting the noise, vibration and acoustic roughness performance (Noise, Vibration, Harshness, NVH performance) of the vehicle, and meeting different usage requirements.

[0036] It should be noted that, for the convenience of description, the directions such as “upper” and “lower” in the present invention are based on the directions shown in the accompanying drawings, and are not limitations on the directions in actual application.

[0037] In some embodiments, the sound insulation member 100 may be a polyethylene terephthalate (PET) and glass fiber member, a PET and polyurethane (PU) member, or a cotton felt member, all of which can meet the sound insulation requirements of the sound insulation member 100 and ensure a better sound insulation effect.

[0038] In some embodiments, the operating inlet 21 is cut into a desired shape by a water jet or a mold blade, ensuring that the cut shape is accurate and meets the requirements, thereby facilitating the disassembly of the virtual cut hole 20 .

[0039] According to the sound insulation member 100 of the embodiment of the utility model, the sound insulation body 10 is provided with a mounting hole, and the virtual cut hole position 20 is removably provided in the mounting hole. The virtual cut hole position 20 is provided with an operation entrance 21 that penetrates the virtual cut hole position 20 in the thickness direction. The virtual cut hole position 20 can be quickly removed through the operation entrance 21, which is convenient for the mounting hole to achieve the required assembly requirements, and can reduce the harm to the production personnel and ensure the stability of the production rhythm. At the same time, when the mounting hole is not needed, the virtual cut hole position 20 does not need to be removed, ensuring the NVH performance of the vehicle and meeting different usage requirements.

[0040] In some embodiments of the present invention, Figure 2-Figure 4 As shown, at least a portion of the virtual cut hole 20 is formed toward one side of the thickness direction of the sound insulation body 10 (for example Figure 3 The operation boss 22 protrudes from the upper side (as shown in the figure), and the operation entrance 21 is arranged on the operation boss 22. The operation boss 22 can increase the operation space at the operation entrance 21, which is convenient for operation and makes the removal of the virtual cut hole 20 more convenient.

[0041] According to some embodiments of the present invention, Figure 3 As shown, the side of the operating boss 22 facing the sound insulation body 10 (eg Figure 3 ) and one side of the sound insulation body 10 facing the operating boss 22 (e.g. Figure 3 The spacing between the side of the operating boss 22 facing the sound insulation body 10 and the side of the sound insulation body 10 facing the operating boss 22 is 15mm-20mm, that is, the spacing between the side of the operating boss 22 facing the sound insulation body 10 and the side of the sound insulation body 10 facing the operating boss 22 is H and satisfies 15mm≤H≤20mm. Within the above-mentioned size range, the required operating space requirements can be met, for example, the thickness requirements of the fingers can be met, the convenience of operation is improved, and the structural strength of the virtual cut hole 20 and the sound insulation body 10 can be ensured. For example, in some specific embodiments, the spacing between the side of the operating boss 22 facing the sound insulation body 10 and the side of the sound insulation body 10 facing the operating boss 22 can be 15mm, 16mm, 17mm, 18mm, 19mm, 20mm, etc.

[0042] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the width of the operation entrance 21 is 5mm-10mm, that is, the width of the operation entrance 21 is W and satisfies 5mm≤W≤10mm, and the length of the operation entrance 21 is 20mm-25mm, that is, the length of the operation entrance 21 is L and satisfies 20mm≤L≤25mm. Within the above-mentioned size range, the required operating space requirements can be met, for example, the width requirements of the fingers can be met, the convenience of operation is improved, and the operation entrance 21 can be prevented from being too large and affecting the overall structural strength of the sound insulation member 100. For example, in some specific embodiments, the width of the operation entrance 21 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. For example, in some specific embodiments, the length of the operation entrance 21 can be 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, etc.

[0043] In some embodiments, Figure 4 As shown, the sound insulation member 100 further includes a shielding portion 31 and a connecting portion 32. The shielding portion 31 covers the operating entrance 21. The connecting portion 32 is used to connect the shielding portion 31 and the virtual cut hole 20. The connecting portion 32 can be bent. Therefore, when the mounting hole needs to be used in the final assembly process, the fingers or operating tools of the production personnel can press the shielding portion 31 to make the connecting portion 32 bend and deform, so that the fingers or operating tools of the production personnel can reach into the operating entrance 21 to pull and remove the virtual cut hole 20, thereby achieving rapid removal. At the same time, when the mounting hole is not needed, the virtual cut hole 20 does not need to be removed, and the shielding portion 31 can shield the operating entrance 21, thereby avoiding the reduction of the sound insulation performance of the sound insulation member 100, ensuring the integrity of the sound insulation member 100, and improving the NVH performance.

[0044] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the virtual cut hole 20 includes a virtual cut body 201 and a connecting rib 203. The virtual cut body 201 is removably arranged in the mounting hole. A virtual cut slit 202 is formed between the outer peripheral wall of the virtual cut body 201 and the hole wall of the mounting hole. The connecting rib 203 is arranged in the virtual cut slit 202. The connecting rib 203 can connect the sound insulation body 10 and the virtual cut body 201 located on both sides of the virtual cut slit 202, so that the virtual cut body 201 can cover the mounting hole and ensure the integrity of the sound insulation component 100. The operation entrance 21 is arranged on the virtual cut body 201, so that it is more convenient to pull the virtual cut body 201. At the same time, the virtual cut body 201 can be removed by only disconnecting the connecting rib 203, which can be quickly removed and is conducive to improving assembly efficiency.

[0045] In some embodiments, Figure 2 and Figure 4As shown, there are multiple connecting ribs 203, and a virtual slit 204 is defined between any two adjacent connecting ribs 203. When there is no need to use the mounting hole, the multiple connecting ribs 203 can ensure that the virtual cut body 201 is reliably fixed in the mounting hole. When the mounting hole is needed, the virtual cut body 201 can be removed more conveniently through the virtual slit 204, making the connecting ribs 203 easier to break, which is beneficial to improving assembly efficiency.

[0046] In some embodiments, Figure 2 and Figure 4 As shown, the virtual slits 204 are evenly distributed along the circumferential direction of the mounting hole, which is convenient for processing and manufacturing and makes disassembly more convenient.

[0047] In the embodiment of the present invention, the number of sub-shearing slits can be flexibly set according to actual conditions. For example, the sub-shearing slits can be Figure 2 Three are shown, but there may also be two, four, five, six or more, all of which are within the protection scope of the present utility model.

[0048] In some embodiments, the virtual cut slit 204 is formed into a desired shape by cutting with a water jet or a mold blade, ensuring that the cut shape is accurate and meets the requirements, thereby facilitating the disassembly of the virtual cut hole 20 .

[0049] In some embodiments, Figure 2 As shown, the width of the virtual cut slit 202 is 0.5mm-2mm, that is, the width of the virtual cut slit 202 is B and satisfies 0.5mm≤B≤2mm. Within the above size range, it is easy to remove the virtual cut body 201, and avoid the virtual cut slit 202 being too wide to affect the sound insulation performance of the sound insulation member 100. For example, in some specific embodiments, the width of the virtual cut slit 202 can be 0.5mm, 0.8mm, 1mm, 1.2mm, 1.5mm, 1.8mm, 2mm, etc.

[0050] In some embodiments of the present invention, the sound insulation member 100 may be an integral part, in other words, the sound insulation body 10 and the virtual cut hole 20 may be an integral part, which is simple to manufacture, has high connection strength, reduces assembly steps, and has high production efficiency. For example, the sound insulation body 10 and the virtual cut hole 20 are an integral molded part.

[0051] According to some embodiments of the utility model, there can be multiple (greater than or equal to two) mounting holes, and the multiple mounting holes are arranged at intervals on the sound insulation body 10, and the virtual cut hole positions 20 are multiple and correspond to the mounting holes one by one. Therefore, when the mounting holes are required in the final assembly process, multiple mounting holes can meet a variety of different installation requirements, and the virtual cut hole positions 20 can be quickly removed to meet the required assembly requirements; when the mounting holes are not needed, there is no need to remove the virtual cut hole positions 20, which can avoid weakening the sound insulation performance of the sound insulation component 100, thereby avoiding affecting the NVH performance of the vehicle and meeting different usage requirements. For example, the mounting holes can include wiring harness holes, electronic control unit (ECU) bracket mounting holes, air conditioning pipe mounting holes, etc.

[0052] In the related art, different vehicles have different configurations, and different vehicle configurations correspond to a sound insulation component, that is, regardless of whether there are configuration components that need to be installed, corresponding installation holes are added to the sound insulation components, which will result in additional installation holes in places where there are no configuration components, greatly weakening the sound insulation performance and affecting the NVH performance of the entire vehicle; or, different configurations correspond to different sound insulation components, that is, there are as many types of sound insulation components as there are types of configuration components that need to be installed, resulting in a large number of types of sound insulation components, inconvenient production management, increased production management costs, and prone to problems such as wrong installation and repairs.

[0053] Therefore, in the present invention, virtual cut holes 20 are provided on multiple mounting holes. When the mounting holes are needed in the final assembly process, the virtual cut holes 20 can be quickly removed to meet the required assembly requirements; when the mounting holes are not needed, the virtual cut holes 20 do not need to be removed, which can avoid weakening the sound insulation performance of the sound insulation member 100, thereby avoiding affecting the NVH performance of the vehicle. In this way, the problem of universalization of the sound insulation member 100 caused by the rich configuration and diversified optional equipment of the vehicle is solved, and the NVH performance of the vehicle is avoided. The universality of the sound insulation member 100 can be achieved, and the flexibility of the sound insulation member 100 to cope with multiple configurations is achieved, which reduces the production management cost of differentiated parts, simplifies the production management process, and effectively avoids the problems of wrong installation and rework that are easy to occur in the final assembly process, thereby significantly improving production efficiency and product quality.

[0054] In some embodiments, the vehicle includes a cabin front panel, and the sound insulation 100 is opposite to or in contact with the cabin front panel, which can effectively reduce the vibration in the engine compartment and the transmission of noise into the cockpit, thereby improving the user experience. In addition, the cabin front panel has different installation holes according to the differentiated configuration parts, and the sound insulation 100 removes the corresponding virtual cut hole positions 20 according to the different installation holes set to meet the required assembly requirements, and there is no need to remove the virtual cut hole positions 20 at the position where the cabin front panel is not provided with the installation hole, so that the virtual cut hole positions 20 can block the unnecessary installation holes, thereby ensuring the NVH performance of the vehicle.

[0055] In the embodiment of the utility model, the specific structure of the sound insulation member 100 can be set according to the actual situation. For example, the sound insulation member 100 can be pressed and formed by a mold according to the shape structure of the sheet metal parts and peripheral parts of the vehicle to meet the required shape requirements.

[0056] The vehicle according to the embodiment of the utility model includes the sound insulation 100 according to the embodiment of the utility model. Since the sound insulation 100 according to the embodiment of the utility model has the above-mentioned beneficial technical effects, the vehicle according to the embodiment of the utility model has a mounting hole provided on the sound insulation body 10, and the virtual cut hole position 20 is removably provided in the mounting hole, and the virtual cut hole position 20 is provided with an operation entrance 21 that penetrates the virtual cut hole position 20 in the thickness direction, and the virtual cut hole position 20 can be quickly removed through the operation entrance 21, which is convenient for the mounting hole to achieve the required assembly requirements, and can reduce the harm to the production personnel, and ensure the stability of the production rhythm. At the same time, when the mounting hole is not needed, the virtual cut hole position 20 does not need to be removed, ensuring the NVH performance of the vehicle and meeting different usage requirements.
