Description

Technical Field

[0001] This utility model relates to the field of vehicle interior technology, specifically to a carpet assembly and a vehicle. Background Technology

[0002] Heavy truck cabs have large spaces, resulting in a correspondingly large carpet area. Existing carpet designs typically divide a large carpet area into three independent sections (left, center, and right) along the left-right direction, with adjacent sections secured by overlapping. Some designs, due to the long front-to-back distance of the cab, divide the carpet into two sections, front and back, also using an overlapping method. However, this overlapping method has significant drawbacks: firstly, the large gaps between the overlapping sections cause the carpet to easily shift laterally or forward-backward while the driver is walking, affecting not only walking comfort but also potentially causing wrinkles and affecting the appearance; secondly, when vehicle body parts need to be inspected, maintenance personnel must first remove the carpet, but the numerous pressing parts around the carpet make disassembly difficult and increase maintenance time.

[0003] In conclusion, how to improve existing carpet designs is a question worth exploring. Utility Model Content

Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] The following is for reference. Figures 1-7 The carpet assembly 10 according to an embodiment of the present utility model is described.

[0024] like Figure 1 As shown, the carpet assembly 10 according to an embodiment of the present utility model includes: a carpet body 1, a maintenance cover 2, and a decorative pad 3.

[0025] like Figure 1 , Figure 8 As shown, the carpet body 1 is used to cover the vehicle floor 101. The carpet body 1 has a carpet opening 11, which is used to avoid the maintenance opening 1011 on the vehicle floor 101. At least a portion of the maintenance cover 2 is located inside the carpet opening 11 to open and close the maintenance opening 1011. A decorative pad 3 is provided on the carpet body 1 and completely covers the maintenance cover 2. The decorative pad 3 is detachably connected to the carpet body 1.

[0026] The overall shape of the carpet body 1 matches the outline of the vehicle floor 101 in the cab of the vehicle 200. After being laid, the carpet body 1 can completely cover the surface of the vehicle floor 101. A maintenance port 1011 is provided on the vehicle floor 101. A carpet opening 11 is specially made on the carpet body 1. The position, size and shape of the carpet opening 11 correspond to the maintenance port 1011. This allows the carpet opening 11 to avoid the maintenance port 1011 when the carpet body 1 is laid flat on the vehicle floor 101. Therefore, unlike the traditional solution, it is not necessary to remove a large area of ​​carpet for maintenance. Instead, the wiring harness, pipeline or control module and other components that require regular inspection or maintenance can be directly inspected or maintained through the carpet opening 11. This greatly simplifies the operation process of maintenance personnel and shortens the maintenance preparation time.

[0027] The maintenance cover 2, as a key functional component for opening and closing the maintenance opening 1011, has at least a portion located within the carpet opening 11. The periphery of the maintenance cover 2 is connected to the vehicle floor 101 via a suitable connecting structure; the maintenance cover 2 can be removed to expose the maintenance opening 1011 simply by disassembling the connecting structure. When the vehicle 200 is in normal use, the maintenance cover 2, in its closed state, remains flush with or smoothly transitions to the upper surface of the carpet body 1, ensuring the cleanliness and flatness of the carpet assembly 10 in the driver's cab. When it is necessary to inspect the components below the maintenance opening 1011, maintenance personnel only need to remove the maintenance cover 2 to expose the maintenance opening 1011, allowing for convenient inspection, maintenance, or replacement of the components below the maintenance cover 2. After inspection, the maintenance cover 2 is reinstalled on the vehicle floor 101 to cover the maintenance opening 1011. This design of the maintenance cover 2 effectively prevents dust, debris, or foreign objects from entering the maintenance opening 1011, and its independent design also significantly reduces maintenance time during inspections.

[0028] The decorative pad 3 is laid on the upper surface of the carpet body 1. The shape of the decorative pad 3 is designed to completely cover the area where the maintenance cover 2 is located (i.e., the carpet opening 11 and the maintenance cover 2 itself), thus achieving the function of concealing the maintenance area while matching the overall style of the carpet body 1. The decorative pad 3 is fixed to the carpet body 1 through a detachable connection structure. While covering the maintenance area, the decorative pad 3 further enhances the overall aesthetics of the carpet assembly 10.

[0029] Optionally, the decorative pad 3 has a two-layer structure. The surface of the decorative pad 3 can be designed as a rigid polyethylene surface or a tufted soft surface, depending on the specific situation. The bottom layer can be made of lightweight cross-linked polyethylene foam. The perimeter of the decorative pad 3 is designed with practical edging.

[0030] In some embodiments, refer to Figure 1 The carpet assembly 10 also includes a strip 4, which is located at the edge of the decorative pad 3; the carpet body 1 is provided with a first clearance hole 12, and the strip 4 is provided with a first connecting part 41 located at the first clearance hole 12 to connect to the vehicle floor 101; a part of the strip 4 presses on the decorative pad 3 and a part presses on the carpet body 1.

[0031] Specifically, such as Figure 1 , Figure 2 , Figure 8 As shown, the carpet body 1 has a first clearance hole 12 at a position corresponding to the edge of the decorative pad 3. The position and size of the first clearance hole 12 are precisely matched with the first connecting part 41 provided on the pressure strip 4. The first connecting part 41 of the pressure strip 4 can pass through the first clearance hole 12 and reliably connect with the preset installation position on the vehicle floor 101, so that there is no gap between the decorative pad 3 and the carpet body 1.

[0032] like Figure 2 , Figure 3 As shown, during actual assembly, one side of the pressure strip 4 is tightly pressed against the upper surface of the carpet body 1, while the other side of the pressure strip 4 is pressed against the edge of the decorative pad 3. By pressing both sides of the pressure strip 4 against the upper surfaces of the decorative pad 3 and the carpet body 1, a firm fit between the decorative pad 3 and the carpet body 1 is achieved. This also ensures that the edge of the decorative pad 3 is firmly fixed to the upper surface of the carpet body 1, thereby effectively preventing the decorative pad 3 from curling, lifting, or shifting due to people stepping on it or friction during use.

[0033] In summary, the contact area between the strip 4 and the carpet body 1 and the decorative pad 3 is designed to ensure that the surfaces of the carpet body 1 and the decorative pad 3 are flat and tightly fitted, eliminating gaps between them. This ensures the smoothness and consistency of the carpet assembly 10's appearance and further enhances the connection stability between the components. As a result, the carpet assembly 10 can maintain good structural integrity and aesthetics during long-term use, improving the user experience and interior quality.

[0034] In some embodiments, refer to Figure 1 , Figure 2 The first connecting portion 41 is a recessed platform formed on the pressure strip 4, and a first connecting hole 411 is provided on the recessed platform. The carpet assembly 10 also includes a first fastener 5 fitted into the first connecting hole 411, and the carpet assembly 10 also includes a cap 6 connected to the pressure strip 4 and covering the recessed platform.

[0035] like Figure 2 , Figure 8 As shown, the carpet body 1 has a first clearance hole 12, and the strip 4 has a recessed platform, which is also the first connecting part 41, formed on it. The recessed platform passes through the first clearance hole 12 of the carpet body 1, and a first connecting hole 411 is provided on the recessed platform. The first connecting hole 411 is used to pass through the first fastener 5. The first fastener 5 is passed through the first connecting hole 411 and fastened to a preset mounting position on the vehicle floor 101 (such as a pre-embedded nut, welded stud, or connecting hole on a metal bracket). The first fastener 5 tightly connects the carpet assembly 10 to the vehicle floor 101, preventing the carpet assembly 10 from moving around in the cab and misaligning with surrounding parts.

[0036] In addition, to maintain the cleanliness and aesthetics of the carpet assembly 10, a cover 6 is installed on the pressure strip 4. The cover 6 covers the lower recess 41 and completely covers the first connecting hole 411 and the first fastener 5. This ensures that the first fastener 5 is not contaminated by dust or other contaminants, and also cleverly hides the connection structure between the pressure strip 4 and the vehicle floor 101. This ensures the smoothness and consistency of the overall appearance of the carpet assembly 10, further improves the connection stability and assembly reliability between the components, and makes the carpet assembly 10 meet the requirements of convenient maintenance and aesthetics while also having excellent structural stability and durability.

[0037] In other specific embodiments, such as Figure 1 , Figure 3As shown, the upper surface of the pressure strip 4 is provided with an anti-slip structure 42 (such as anti-slip texture, raised dots, or frosted surface). This anti-slip structure 42 can effectively increase the friction between the sole of the foot and the surface of the pressure strip 4 under extreme weather conditions (such as when the soles of people's shoes are wet or muddy in rainy or snowy weather), thereby ensuring the safety of people walking, getting in and out of the vehicle, or moving in the cab and preventing slipping or falling. In addition, the lower surface of the pressure strip 4 is provided with reinforcing support ribs 43. The bottom of these reinforcing support ribs 43 is tightly connected to the upper surface of the carpet body 1. This not only improves the structural rigidity and bending resistance of the pressure strip 4 itself, ensuring that the pressure strip 4 is not easily deformed under long-term stepping or pressure, but also enhances the bonding stability between the pressure strip 4 and the carpet body 1 and the decorative pad 3, effectively preventing the pressure strip 4 from warping, shifting, or loosening, and further improving the overall durability and reliability of the carpet assembly 10 in the cab.

[0038] In some embodiments, refer to Figure 4 The carpet body 1 has two spaced seating areas 13, a portion of the decorative pad 3 is located between the two seating areas 13, and the strip 4 is located between the two seating areas 13 and extends along the arrangement direction of the two seating areas 13.

[0039] The two seat mounting areas 13 provide a direct mounting base for the subsequent fixing of the seats. The seat mounting areas 13 usually need to be directly connected to the mounting brackets at the bottom of the seats. Therefore, a portion of the carpet body 1 needs to be exposed on its surface to ensure that the seat mounting components can be smoothly inserted.

[0040] In other specific embodiments, such as Figure 4 , Figure 8 As shown, the installation point 131 of the seat installation area 13 can be partially cut at the carpet body 1, while the carpet body 1 is retained at the non-installation point of the seat base. This design can ensure that the seat installation point is fixed on the vehicle body 100, and also ensure that the non-installation point area of ​​the seat base is also covered by the carpet body 1.

[0041] The area between the two seat mounting areas 13 is usually a high-traffic area prone to dirt accumulation, such as when the driver gets in and out of the vehicle, they may kick or rub against it, and dust, mud, and other dirt carried by shoes during daily use can easily fall into this area. Part of the decorative pad 3 covers the area between the seat mounting areas 13, which can effectively protect the carpet body 1 in this area from direct wear and tear, reduce dirt adhesion, and facilitate cleaning and maintenance. Stains can be easily removed by treating the decorative pad 3 separately.

[0042] The pressure strip 4 extends along the arrangement direction of the two seat mounting areas 13 and is located between the two seat mounting areas 13. On the one hand, the pressure strip 4 cooperates with the first fastener 5 through the first connecting hole 411 of the pressure strip 4 to firmly connect the pressure strip 4 to the vehicle floor 101, thereby clamping and fixing the edge of the decorative pad 3 (the part covering the two seat mounting areas 13) and the corresponding area of ​​the carpet body 1, ensuring that the decorative pad 3 will not shift due to vibration during seat installation or personnel movement. On the other hand, the extension layout of the pressure strip 4 matches the spacing arrangement direction of the two seat mounting areas 13, which can cover the key transition area between the two seat mounting areas 13 and enhance the integrity of the seat mounting area 13 area.

[0043] In some embodiments, refer to Figure 1 The carpet assembly 10 also includes at least one of the following snap-fit ​​structures: a first snap-fit ​​assembly 7 disposed between the decorative pad 3 and the carpet body 1; a second snap-fit ​​assembly 8 disposed on the carpet body 1 to connect the vehicle floor 101; and a third snap-fit ​​assembly 9 disposed on the maintenance cover 2 to connect the vehicle floor 101.

[0044] The first snap-fit ​​assembly 7 is located between the decorative pad 3 and the carpet body 1. If multiple snap-fit ​​parts 71 (such as protrusions or claws) are provided on the surface of the decorative pad 3, a matching snap-fit ​​part 72 (such as a slot, groove, or limiting hole) is provided on the carpet body 1. Alternatively, multiple snap-fit ​​parts 71 (such as protrusions or claws) are provided on the carpet body 1, and a matching snap-fit ​​part 72 (such as a slot, groove, or limiting hole) is provided on the decorative pad 3.

[0045] For ease of explanation, let's use Figure 5 For example, the carpet body 1 is provided with a snap-fit ​​part 71, and the decorative pad 3 is provided with a snap-fit ​​mating part 72. By pressing the carpet body 1, the snap-fit ​​part 71 is inserted into the snap-fit ​​mating part 72 on the decorative pad 3, thus completing the stable connection between the decorative pad 3 and the carpet body 1. When disassembling the decorative pad 3, only appropriate external force needs to be applied to separate it, realizing the quick disassembly and assembly of the decorative pad 3, which is convenient for cleaning or replacement.

[0046] like Figure 6 , Figure 8 As shown, the second snap-fit ​​assembly 8 is provided on the carpet body 1 to connect to the vehicle floor 101. A snap-fit ​​point of the second snap-fit ​​assembly 8 is provided on the surface of the carpet body 1, and a corresponding snap-fit ​​part is provided on the corresponding location of the vehicle floor 100. After the carpet body 1 is laid on the vehicle floor 101, the second snap-fit ​​assembly 8 securely locks the carpet body 1 to the vehicle floor 101, preventing the carpet assembly 10 from sliding or shifting due to bumps or foot traffic during vehicle operation.

[0047] like Figure 6 , Figure 8As shown, the third latching assembly 9 is provided on the maintenance cover 2 to connect to the vehicle floor 101. When it is necessary to repair the parts under the vehicle floor 101, the maintenance personnel only need to remove the third latching assembly 9 to open the maintenance cover 2 to expose the maintenance port 1011, which facilitates the maintenance personnel to carry out the repair.

[0048] Through the combined application of the first snap-fit ​​component 7, the second snap-fit ​​component 8, and the third snap-fit ​​component 9, the carpet assembly 10 achieves efficient and stable assembly of the decorative pad 3, the carpet body 1, and the maintenance cover 2 with the corresponding connecting parts (vehicle floor 101 or other components): the first snap-fit ​​component 7 ensures that the decorative pad 3 can be quickly disassembled and reliably fixed, the second snap-fit ​​component 8 ensures that the carpet body 1 and the vehicle floor 101 fit tightly together, and the third snap-fit ​​component 9 assists the maintenance cover 2 in convenient opening and closing and stable closure. The three components work together to improve the overall reliability and ease of operation of the carpet assembly 10.

[0049] In some embodiments, refer to Figure 6 At least a portion of the snap-fit ​​structure is arranged along the edge of the carpet opening 11.

[0050] like Figure 1 , Figure 5 , Figure 6 , Figure 8 As shown, when the carpet assembly 10 includes a first snap-fit ​​assembly 7 between the decorative pad 3 and the carpet body 1, a second snap-fit ​​assembly 8 between the carpet body 1 and the vehicle floor 101, and a third snap-fit ​​assembly 9 between the service cover 2 and the vehicle floor 101, at least some of the snap-fit ​​units are arranged to be distributed along the edge of the carpet opening 11.

[0051] The connecting structures in the first snap-fit ​​assembly 7 are spaced apart at the edge of the decorative pad 3 near the carpet body 1, and cooperate with the corresponding structures on the upper surface of the carpet body 1 to tightly fix the opening edge of the decorative pad 3 to the opening edge of the carpet body 1; such as Figure 6 As shown, the fixing structure in the second buckle assembly 8 can be set along the middle of the carpet body 1 and connected to the corresponding mating part on the vehicle floor 101 to ensure that the carpet body 1 will not move easily when laid on the vehicle floor 101; the closing structure in the third buckle assembly 9 is set at the edge of the maintenance cover 2 so that when the maintenance cover 2 is closed, a continuous pressing force is formed along the edge of the carpet opening 11.

[0052] In some embodiments, refer to Figure 1 , Figure 7 , Figure 8 At least one of the carpet body 1 and the maintenance cover 2 includes: a first hard layer 14 and a soft layer 15, wherein the soft layer 15 is disposed at the bottom of the first hard layer 14 and is a porous sound-absorbing layer.

[0053] Specifically, both the carpet body 1 and the maintenance cover 2 include a first hard layer 14 and a soft layer 15. The carpet body 1 is provided with the first hard layer 14 and the soft layer 15 from top to bottom and is tightly attached to the vehicle floor 101 to form a sandwich composite structure of "hard support - porous sound absorption - rigid reflection".

[0054] For ease of explanation, let's take carpet body 1 as an example, such as... Figure 7 As shown, when noise travels from the bottom of the cab to the cab, it is initially attenuated by the vehicle floor 101. The penetrating sound waves then enter the soft layer 15. The porous sound-absorbing layer 15, with its numerous interconnected tiny pores, causes intense viscous friction and thermal conduction between air molecules and pore walls during propagation, converting sound energy into internal energy and thus achieving noise attenuation. Subsequently, the remaining unabsorbed sound waves are reflected from the first hard layer 14 back to the soft layer 15. The soft layer 15, with its porous structure, absorbs the sound waves a second time, forming a spring-like sound-absorbing mechanism. After this cycle, the noise ultimately entering the cab is significantly reduced, and this design effectively achieves noise reduction.

[0055] In some embodiments, refer to Figure 1 , Figure 7 Both the carpet body 1 and the maintenance cover 2 include: a first hard layer 14 and a soft layer 15; and the maintenance cover 2 also includes: a second hard layer 21, which is connected to the bottom of the soft layer 15; the soft layer 15 is a foam layer and is fixedly connected to the first hard layer 14 by foaming.

[0056] When the maintenance cover 2 and the carpet body 1 have the same first hard layer 14 and soft layer 15, the maintenance cover 2 also includes a second hard layer 21. The second hard layer 21, soft layer 15, and first hard layer 14 form a three-layer structure: the second hard layer 21 is the load-bearing layer, the soft layer 15 is the middle layer, and the first hard layer 14 is the surface layer. The materials of the first hard layer 14 and soft layer 15 in the carpet body 1 and the maintenance cover 2 can be the same. The material of the second hard layer 21 of the maintenance cover 2 is metal, ensuring that the structure has reliable load-bearing capacity when people step on the second hard layer 21.

[0057] In other specific embodiments, the first rigid layer 14 is typically made of nitrile rubber or ethylene, formed by a roll forming process. To effectively block sound sources, this surface layer is designed as a multi-layered structure with a high density, typically with a mass per unit area of ​​2000 g / m². 2 Up to 5000g / m 2 The soft layer 15 is made of polyurethane foam or cross-linked polyethylene foam through a foaming process. The soft layer 15 has a high-density and porous structure, typically with a density range of 90 kg / m³. 3 Up to 150kg / m3 .

[0058] During the molding process, the first rigid layer 14 needs to be made with a specific profile according to the matching requirements of surrounding components—first, the required profile is formed through a molding process, and then it is placed into a foaming mold so that the foam material is foamed and molded on the other side of the first rigid layer 14 (i.e., the side in contact with the soft layer 15). This process ensures a strong bond between the foam layer and the rigid surface layer, avoiding delamination problems. In addition, the back of the carpet assembly 10 is designed to perfectly match the shape of the cab floor 101, allowing it to fit tightly against the floor surface, thereby further improving the noise reduction effect.

[0059] In some embodiments, refer to Figure 4 , Figure 8 A portion of the carpet body 1 constitutes a seat cover 16, at least one side of the seat cover 16 is connected to the rest of the carpet body 1; at least three connected sides of the seat cover 16 are cut away from the rest of the carpet body 1 so that the seat cover 16 can be lifted and covered at the junction of the seat and the vehicle floor 101.

[0060] It should be noted that, to meet maintenance needs, the rule for disassembling parts is: remove the parts installed later first. The carpet has a lower disassembly rate compared to the seats; therefore, to ensure convenient seat installation and removal, the carpet is usually installed first, followed by the seats. However, for safety reasons, the seats are installed on the vehicle floor 101 and cannot be fixed to the carpet: the carpet has a certain thickness and is a soft component, making the seats unstable when installed on it. Therefore, considering both maintenance and installation needs, this embodiment cuts a slit in the carpet body 1 for the seat cover 16, lifting the seat cover 16 from one side of the slit to expose the seat installation area 13 for seat installation.

[0061] In other words, at least one side of the seat cover 16 (such as the rear side or one of the side sides) remains connected to the rest of the carpet body 1, while the remaining at least three sides (such as the front side and the two side sides) are separated from the rest of the carpet body 1 by a cutting process, forming a liftable movable part. When the seat is installed, the operator can lift the seat cover 16 from one of the notches to expose the installation space for the seat; after installation, the lifted seat cover 16 is reset and naturally covers the connection between the seat and the vehicle floor 101, which not only effectively covers the connection area, but also avoids the exposure of the seat mounting point, eliminating the need for the additional mounting point cover in the traditional solution, reducing the number of parts and assembly costs, while also ensuring that the non-mounting points under the seat are also covered by the carpet body 1, reducing noise transmission.

[0062] The vehicle 200 according to this utility model includes a body 100 and a carpet assembly 10.

[0063] like Figure 1 , Figure 8 As shown, the vehicle body 100 has a vehicle body floor 101, on which a maintenance port 1011 is provided; the carpet assembly 10 is provided on the vehicle body floor 101, and the carpet opening 11 of the carpet body 1 is positioned directly opposite the maintenance port 1011.
