[0025] Please refer to the reference. Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the interior door panel assembly of the vehicle according to an embodiment of the present application before assembly. Figure 2 yes Figure 1A schematic diagram of the assembled interior door panel assembly. In one aspect of this application, an interior door panel assembly 100 is provided, comprising an outer layer panel 1, an inner layer panel 2, a reinforcing component 3, and a sound insulation component 4. The inner layer panel 2 includes a panel body 21 and a connecting portion 22. The connecting portion 22 is disposed at the edge of the panel body 21, and together with the panel body 21, forms a receiving cavity 23 with an opening. The outer layer panel 1 is connected to the connecting portion 22 and seals the opening. The reinforcing component 3 is disposed within the receiving cavity 23, connected to the panel body 21, and abuts against the inner wall of the connecting portion 22 within the receiving cavity 23. The sound insulation component 4 is disposed within the receiving cavity 23, conforming to the shape of the receiving cavity 23, and the opposite sides of the sound insulation component 4 are respectively connected to the reinforcing component 3 and the outer layer panel 1. The reinforcing component 3 of this application embodiment can enhance the bending and impact resistance of the interior door panel assembly 100, thereby extending its service life; while the sound insulation component 4, which is designed to conform to the cavity 23, can reduce the transmission of external noise and improve the sound insulation effect.

[0026] Specifically, by providing a reinforcing component 3 and a sound-insulating component 4 between the outer layer 1 and the inner layer 2, the interior door panel assembly 100 of this application embodiment significantly improves the sound insulation effect while ensuring structural strength. The outer layer 1 is used to cover and protect the external structure of the interior door panel assembly 100. The inner layer 2 consists of a panel body 21 and a connecting part 22. The panel body 21 is the main supporting part of the inner layer 2, and the connecting part 22 is located at the edge of the panel body 21, forming an accommodating cavity 23 with an opening together with the panel body 21. This opening is sealed by the connection between the outer layer 1 and the connecting part 22, thereby forming a sealed structure. The reinforcing component 3 is disposed in the accommodating cavity 23, with one side connected to the panel body 21 and the other side abutting against the inner wall of the connecting part 22 located in the accommodating cavity 23, thereby enhancing the overall strength of the door panel assembly. The sound-insulating component 4 is disposed in the accommodating cavity 23 and matches the shape of the accommodating cavity 23 to improve its stability in the accommodating cavity 23, thereby improving the sound insulation effect. The two ends of the sound insulation component 4 are respectively connected to the reinforcing component 3 and the outer layer plate 1 to form a complete sound insulation structure.

[0027] In one specific embodiment, the thickness of the inner layer 2 plate 21 can be 2mm, and the height of the connecting part 22 relative to the plate 21 can be between 20mm and 26mm, so as to accommodate the reinforcing component 3 and the sound insulation component 4 and other structures.

[0028] In one embodiment of this application, as Figure 1 As shown, the reinforcing component 3 has a honeycomb structure.

[0029] Specifically, a honeycomb structure is composed of multiple hexagonal units. This structure is characterized by high strength and lightweight. By adopting a honeycomb structure, the strength and rigidity of the interior door panel assembly 100 can be significantly improved while reducing weight. This structure can effectively disperse stress when subjected to external forces, thereby improving safety. In addition, the honeycomb structure has a high material utilization rate, which helps to reduce production costs. These characteristics make the vehicle's interior door panel assembly 100 more durable and cost-effective.

[0030] Furthermore, the honeycomb structure also helps to disperse and absorb noise, improving the sound insulation of the interior door panel assembly 100. When noise strikes the surface of the honeycomb reinforcing component 3, the hexagonal grids break the sound waves into countless tiny sound waves, forcing them to change direction. These tiny sound waves repeatedly reflect and collide with each other between the dense honeycomb walls, causing the energy to gradually weaken through mutual cancellation. The originally orderly propagating sound waves become fragmented after passing through the honeycomb reinforcing component 3, ultimately achieving the effect of dispersing noise. In addition, each hexagonal unit is equivalent to a small anechoic chamber. When noise enters the honeycomb pores, it compresses the air inside the pores, causing friction between the air and the honeycomb walls or resonance vibration within the pores, converting the kinetic energy of the sound waves into heat energy, ultimately achieving the effect of absorbing noise.

[0031] In one embodiment of this application, the reinforcing component 3 includes a plurality of first reinforcing ribs 31 and a plurality of second reinforcing ribs 32. The plurality of first reinforcing ribs 31 are arranged at intervals along the width direction of the plate 21, and the plurality of second reinforcing ribs 32 are arranged at intervals along the length of the plate 21. Each first reinforcing rib 31 is connected to at least a portion of the second reinforcing ribs 32.

[0032] Specifically, the inner panel 2 is the main structural component of the interior door panel assembly 100. The first reinforcing rib 31 enhances the strength of the panel 21 in the width direction; it is spaced along the width of the panel 21 and can be made of metal materials such as high-strength steel or aluminum. The second reinforcing rib 32 enhances the strength of the panel 21 in the length direction; it is also spaced along the length of the panel 21 and can also be made of metal materials. The first reinforcing rib 31 and the second reinforcing rib 32 are interlocked to form a honeycomb structure, thereby improving the strength and rigidity of the entire interior door panel assembly 100.

[0033] Furthermore, the first reinforcing ribs 31 and the second reinforcing ribs 32 are of the same size, and the spacing between adjacent first reinforcing ribs 31 and the spacing between adjacent second reinforcing ribs 32 are equal, forming a honeycomb structure with a regular shape and neat arrangement, which can further improve the structural strength and enhance the effect of dispersing and absorbing noise.

[0034] In another embodiment, the honeycomb structure can also be achieved in other ways, such as using high-strength plastic or metal materials and manufacturing them through injection molding or stamping processes, so that the first reinforcing rib 31 and the second reinforcing rib 32 are integrally formed. The size of each hexagonal unit can also be adjusted according to actual needs to ensure the strength and rigidity of the overall structure.

[0035] In one embodiment of this application, as Figure 1 As shown, the sound insulation component 4 includes a sound-absorbing layer 41, a damping layer 42, and a foam layer 43. The foam layer 43, the damping layer 42, and the sound-absorbing layer 41 are sequentially stacked and installed between the outer layer plate 1 and the inner layer plate 2. The sound-absorbing layer 41 is connected to the outer layer plate 1, the foam layer 43 is connected to the reinforcing component 3, and the damping layer 42 connects the sound-absorbing layer 41 and the foam layer 43.

[0036] Specifically, the sound-absorbing layer 41 absorbs sound energy, effectively reducing noise transmission. The damping layer 42, located between the sound-absorbing layer 41 and the foam layer 43, primarily absorbs and disperses vibration energy, preventing structural resonance and reducing noise generation. The foam layer 43, connected to the reinforcing component 3, further blocks noise propagation and enhances the overall structural strength and stability. By utilizing the combined effects of the sound-absorbing layer 41, damping layer 42, and foam layer 43 to reduce noise, this layered structure allows each material to function optimally, achieving efficient noise control and vibration reduction, thus enhancing passenger comfort.

[0037] In one embodiment of this application, the sound-absorbing layer 41 includes polyester fiber sound-absorbing cotton, and the thickness of the sound-absorbing layer 41 is between 2 mm and 5 mm.

[0038] Specifically, sound-absorbing cotton made of polyester fiber can effectively reduce the noise level inside the vehicle and improve ride comfort. Polyester fiber sound-absorbing cotton is a commonly used sound-absorbing material that can effectively absorb mid-to-high frequency noise. The thickness range is set between 2mm and 5mm, which ensures sufficient sound absorption while avoiding installation difficulties or increased costs due to excessive thickness. In practice, different thickness values ​​can be selected according to actual needs, such as 2mm, 3mm, 4mm, and 5mm. Through the above structure, not only is the sound absorption performance of the interior door panel assembly improved, but it also has the characteristics of being environmentally friendly and lightweight, helping to reduce the overall vehicle weight and energy consumption. At the same time, the durability of polyester fiber material can improve the stability and reliability of long-term use.

[0039] Furthermore, the thickness of the sound-absorbing layer 41 can be precisely controlled through the manufacturing process, such as by cutting or pressing. In another embodiment, the thickness can also be adjusted according to the actual situation, and in addition to polyester fiber, other fiber materials such as ramie fiber or glass fiber can also be considered as alternatives for the sound-absorbing cotton.

[0040] In one embodiment of this application, the damping layer 42 includes a sound-insulating damping sheet made of butyl rubber and metal foil, and the thickness of the damping layer 42 is between 3 mm and 6 mm.

[0041] Specifically, the damping layer 42 is an important structure for reducing sound propagation and vibration. In this embodiment, the damping layer 42 uses a sound-insulating damping sheet composed of butyl rubber and metal foil. This material combination can effectively reduce sound transmission and has good durability and stability. Butyl rubber is a polymer material with excellent sound insulation performance and chemical stability; the metal foil can enhance structural strength and provide additional reflection, thereby further improving the sound insulation effect. The thickness of the damping layer 42 is controlled between 3mm and 6mm. This thickness range can ensure sufficient sound insulation while avoiding the increase in weight and cost caused by excessive thickness. In specific implementations, different thickness values ​​can be selected according to actual needs, such as 3mm, 4mm, 5mm, 6mm, etc. By adjusting the thickness, the optimal balance point can be found in different application scenarios.

[0042] In one embodiment of this application, the foam layer 43 includes a polyurethane foam board, and the thickness of the foam layer 43 is between 4 mm and 7 mm.

[0043] Specifically, the foam layer 43 is an important component of the sound insulation component 4, providing cushioning and sound absorption functions. Polyurethane foam board is a commonly used foam material with good cushioning performance, air permeability, processability, and sound and heat insulation properties. By connecting the polyurethane foam board to the reinforcing component 3, the overall structural strength and stability can be improved; on the other hand, it can also directly absorb noise or absorb the heat generated on the reinforcing component 3, thereby further blocking the transmission of noise. The thickness of the foam layer 43 is set between 4mm and 7mm, which can be achieved by adjusting the foaming process parameters, such as 4mm, 5mm, 6mm, 7mm, etc. This thickness range provides a cushioning effect without increasing costs or causing insufficient structural strength due to excessive thickness. In practical applications, different polyurethane formulations and foaming conditions can be selected to meet specific performance requirements.

[0044] Please refer to the reference. Figure 3 , Figure 3 This is a schematic diagram of the assembled structure of another embodiment of the vehicle interior door panel assembly of this application. In another embodiment of this application, the outer layer 1 includes an aluminum alloy plate, the thickness of the outer layer 1 is between 0.9 mm and 1.1 mm, and the surface of the outer layer 1 is provided with a sound insulation coating 11.

[0045] Specifically, the outer layer panel 1 is an important component of the interior door panel assembly 100. Aluminum alloy sheet is a high-strength and lightweight material that provides good structural support and impact resistance for the door panel. The thickness of the outer layer panel 1 can be controlled between 0.9mm and 1.1mm, such as 0.9mm, 0.95mm, 1mm, 1.05mm, and 1.1mm, etc., reducing material usage while increasing strength, thereby reducing overall weight and achieving cost reduction and efficiency improvement. Controlling the thickness range is an optimized design under the premise of meeting structural strength requirements, which can both improve the rigidity of the interior door panel assembly 100 and reduce or avoid excessive material waste. The sound-insulating coating 11 applied to the surface of the outer layer panel 1 can effectively reduce the transmission of external noise and improve the quietness of the vehicle interior. The coating process of the sound-insulating coating 11 can be sprayed or electrophoretically coated, ensuring that the coating adheres evenly to the surface of the outer layer panel 1 and improving the sound insulation effect. The choice of aluminum alloy sheet is based on its high strength and lightweight characteristics, which can improve the durability and safety of the door panel without adding excessive weight.

[0046] Furthermore, the outer panel 1 is also provided with a fastener 5, which may include bolts, screws and other structures, and is mainly used for installation and connection with the door frame.

[0047] In another aspect, this application also provides a vehicle door that includes the aforementioned interior door panel assembly 100. Specifically, since the vehicle door includes the interior door panel assembly 100 described in the above embodiments, it also has the beneficial effects of the aforementioned interior door panel assembly 100, which will not be elaborated further here.

[0050] The outer layer 1 is made of aluminum alloy and is formed into the required shape by stamping process, and then a sound insulation coating is sprayed on its surface; the inner layer 2 is made of fiber reinforced composite material and is formed by molding process.

[0051] Next, the reinforcing component 3 is installed inside the receiving cavity 23 of the inner layer plate 2, so that it is distributed in a honeycomb pattern;

[0052] The reinforcing component 3 can be formed by alternating connections of the first reinforcing rib 31 and the second reinforcing rib 32, or it can be integrally molded by processes such as injection molding.

[0053] Then, inside the accommodating cavity 23, according to the design requirements, the foam layer 43, the damping layer 42 and the sound-absorbing layer 41 are filled in sequence from the inside to the outside. The sound-absorbing layer 41 can be glued to the inside of the outer plate 1, the damping layer 42 can be glued to the inside of the sound-absorbing layer 41, and the foam layer 43 can be filled to the inside of the damping layer 42 using a filling mold.
