Description

Technical Field

[0001] This application relates to the technical field of wiring harness installation, and more particularly to a wiring structure and vehicle. Background Technology

[0002] During vehicle production, wiring harnesses need to be installed. In particular, in some vehicles with a dual front bulkhead structure, the wiring harnesses in the engine compartment need to pass through the engine compartment heat insulation pad mounting plate. Since the diameter of the engine compartment wiring harnesses varies among different vehicle configurations, in order to adapt to the installation requirements of various wiring harnesses, existing technologies usually reserve through holes for the engine compartment wiring harness assembly on the engine compartment heat insulation pad mounting plate so that the wiring harnesses can be smoothly passed through and arranged, ensuring the normal connection and operation of the vehicle's electrical system.

[0003] However, the aforementioned existing technical solutions have obvious drawbacks: the wiring harness through holes reserved on the engine compartment heat insulation pad mounting plate will damage the integrity of the small front bulkhead structure. On the one hand, it will damage the structural sealing of the engine compartment area, thereby affecting the overall NVH (Noise, Vibration, Harshness) performance of the vehicle, and exacerbating the transmission of noise and vibration during vehicle operation. On the other hand, the exposed through holes and the messy arrangement of the surrounding wiring harness will seriously affect the aesthetics of the engine compartment interior and will not meet the requirements of the refined design of the overall vehicle appearance and structure. Utility Model Content

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a wiring structure and vehicle in which the wiring harness blocks the mounting groove on the engine compartment heat insulation pad, and the wiring harness passes through the wiring holes on the wiring harness, avoiding direct exposure or messy arrangement of the wiring harness. Compared with the existing technology of reserving through holes, this structure effectively makes up for the integrity defects of the small front bulkhead structure, significantly improves the sealing of the engine compartment area, reduces the transmission of noise and vibration during driving, optimizes the NVH performance of the whole vehicle, and improves the aesthetics.

[0006] To achieve the above objectives, in a first aspect, this application provides a threading structure, comprising: A wire threading component, wherein the wire threading component is made of a flexible sound-absorbing material; and a wire threading hole is provided through the wire threading component; Mounting section, the mounting section being used to mount the wiring component to the forward nacelle frame; The threading component is used to install in the mounting slot of the cabin heat insulation pad and to seal the mounting slot.

[0007] In this technical solution, the wiring harness structure utilizes flexible, sound-absorbing materials for the wiring components. This provides excellent flexibility, allowing for a tight seal within the engine compartment's heat insulation pad mounting slots, while also reducing noise transmission through sound absorption. The wiring holes provide a passageway for the wiring harness, preventing direct exposure or cluttered arrangement. The mounting mechanism ensures the wiring components are securely mounted to the front engine compartment frame, guaranteeing structural reliability. Compared to existing solutions with pre-drilled holes, this structure effectively compensates for the integrity deficiencies of the small front bulkhead structure, significantly improving the engine compartment's sealing performance, reducing noise and vibration transmission during driving, and optimizing the overall vehicle's NVH (noise, vibration, and harshness) performance. Simultaneously, it allows for a more organized wiring harness arrangement, avoiding exposed and cluttered issues, enhancing the engine compartment's aesthetics, meeting the refined requirements of the vehicle's structural design, and the flexible material adapts to different installation scenarios, increasing installation convenience.

[0008] In some embodiments of this application, the two opposite sides of the threading member have an inlet side and an outlet side, respectively, and the rest are peripheral sides; The wire hole passes through the inlet side and the outlet side; One of the peripheral sides has a through groove for wire passing through, which connects the wire through hole to the outside; the through groove passes through the wire inlet side and the wire outlet side.

[0009] In this technical solution, the wire harness can be quickly inserted into the through-hole via the wire channel during assembly, eliminating the need for overall threading and reducing operational difficulty. Subsequent maintenance also allows for convenient removal or adjustment of the wire harness through the wire channel, minimizing disassembly work. This design retains the sealing and sound-absorbing characteristics of the through-hole structure while solving the problems of cumbersome assembly and inconvenient maintenance associated with traditional through-hole wire harnesses. It further enhances the practicality and operability of the through-hole structure, while maintaining the overall structural integrity of the through-hole component, ensuring effective sealing of the mounting slot and NVH optimization.

[0010] In some embodiments of this application, multiple threading holes are provided, and the number of threading grooves is the same as the number of threading holes and they are configured in a one-to-one correspondence.

[0011] In this technical solution, the multiple through-holes allow the structure to simultaneously accommodate the installation of multiple wire harnesses, adapting to complex wiring harness layouts within the vehicle's engine compartment. This avoids tangling and wear issues caused by multiple wire harnesses being mixed and passed through the same hole, reducing the risk of short circuits and malfunctions, and improving the reliability of the electrical system. Each through-hole corresponds to a wire channel, ensuring that each wire harness can be independently assembled and maintained via its dedicated channel, further optimizing operational convenience. During assembly, wire harnesses with different functions can be inserted into their respective through-holes via their corresponding through-channels, enabling categorized wiring harness arrangement and facilitating subsequent troubleshooting and maintenance. During maintenance, only the through-channel corresponding to the target wire harness needs to be operated on, without affecting the normal operation of other wire harnesses. This design, while ensuring sealing, sound absorption, and aesthetics, enhances the adaptability of the wiring structure to multi-wire harness scenarios, making the wiring harness arrangement more organized and conforming to the standardized design requirements of the vehicle's electrical system.

[0012] In some embodiments of this application, when there are multiple threading holes, the diameter of at least one threading hole is different from the diameter of the remaining threading holes.

[0013] The technical solution enables the wiring structure to adapt to the needs of wire harnesses with different diameters. Wire harnesses in the vehicle's engine compartment vary in diameter due to different functions. Traditional uniform-diameter wiring holes either cannot accommodate thicker wire harnesses or leave large gaps for thinner wire harnesses, affecting sealing performance and NVH (noise, vibration, and harshness) performance. This design uses wiring holes of varying diameters, allowing each wire harness to fit tightly into its corresponding hole. This ensures smooth installation of thicker wire harnesses while avoiding gaps between thinner wire harnesses and the holes, enhancing sealing performance and further reducing noise transmission. Simultaneously, the varying diameter design eliminates the need for additional seals or adapter structures, simplifying the overall design and maintaining the simplicity and low cost advantages of the wiring structure while meeting diverse wire harness compatibility requirements.

[0014] In some embodiments of this application, the mounting portion is a mounting hole, which is opened on one circumference of the threaded member, and the mounting hole and the thread groove are located on different circumferences.

[0015] In this technical solution, due to the material of the wiring harness, it is unsuitable for installing other structures. Therefore, a clip can be installed on the forward engine compartment frame. The clip passes through and engages with the mounting hole, ensuring a stable connection between the wiring harness and the forward engine compartment frame. Simultaneously, the side with the mounting hole is necessarily the side of the wiring harness used to fit against the forward engine compartment frame. Therefore, after installing the wiring harness, to avoid the cable channel being blocked by the forward engine compartment frame, the cable channel and the mounting hole are placed on different sidewalls, preventing interference during wiring harness installation. Furthermore, the layout on different sides ensures more even stress distribution on the wiring harness, avoiding structural instability caused by too many openings on one sidewall, resulting in a more rational and compact overall design of the wiring structure.

[0016] In some embodiments of this application, the mounting hole communicates with the wire-passing hole; the mounting hole is located on the side of the wire-passing hole away from the wire-passing groove.

[0017] In this technical solution, the wiring harness is installed behind the front engine compartment frame via mounting holes. The cable tray is located on the side furthest from the front engine compartment frame, making it easier for manual installation of the wire harness through the cable tray into the cable hole. Furthermore, the mounting holes and cable holes are interconnected, simplifying the production process and saving production costs. The mounting holes in this application are through holes; if the length of the clips connected to them is too long, the excess clip length can extend into the cable hole without affecting the installation of the wiring harness. This ensures that the wiring harness fits snugly against the front engine compartment frame, enhancing the stability of the wire harness installation while guaranteeing sealing performance and NVH performance.

[0018] In some embodiments of this application, the threading component is made of sponge.

[0019] In this technical solution, sponge, as a typical flexible sound-absorbing material, possesses excellent sound absorption, sealing, and flexibility properties. In terms of sound absorption, the porous structure of sponge effectively absorbs noise generated during vehicle operation, further blocking the transmission path of noise through the mounting groove and wiring harness gaps, significantly improving the overall vehicle NVH performance. Regarding sealing, sponge has good elasticity, allowing it to tightly conform to the inner wall of the mounting groove and the surface of the wiring harness, maximizing gap filling and enhancing the sealing of the engine compartment area, preventing dust and moisture from entering and protecting the wiring harness and components within the engine compartment. In terms of flexibility, sponge is easy to bend and deform, adapting to the complex shape of the mounting groove, reducing installation difficulty. Simultaneously, when the vehicle vibrates during operation, the elasticity of the sponge can buffer the vibration impact on the wiring harness, reducing wear and fatigue damage and extending its service life. Compared to other flexible sound-absorbing materials, sponge is lower in cost, widely available, and has a simple processing technology, enabling cost reduction for the entire vehicle while ensuring technical effectiveness.

[0020] In addition, this application also provides a vehicle, including: a body and a wiring harness for mounting to the body, wherein the above-described wiring structure is mounted on the body; at least one strand of the wiring harness passes through the wiring hole of the wiring harness.

[0021] In this technical solution, the vehicle employs the aforementioned wiring harness structure, which significantly optimizes the overall NVH performance, reduces driving noise and vibration, and improves ride comfort. Regarding safety, the wiring harness is neatly arranged through the wiring holes, avoiding exposure, tangling, and wear, reducing the risk of short circuits and malfunctions, ensuring the stable operation of the vehicle's electrical system, and enhancing driving safety. In terms of aesthetics, the wiring harness components seal the mounting slots and organize the wiring harness, making the engine compartment layout cleaner and more orderly, meeting the refined requirements of the vehicle's exterior and structural design. In terms of economy, the wiring harness structure uses low-cost materials such as sponge, replacing the traditional cable box structure, achieving the goal of reducing overall vehicle cost and weight, and enhancing the product's market competitiveness. Simultaneously, the wiring harness structure has strong adaptability, meeting the wiring harness layout requirements of vehicles with different configurations, enhancing the versatility and flexibility of vehicle production, and reducing manufacturing costs.

[0022] In some embodiments of this application, a cabin heat insulation pad and a forward cabin frame are included; the cabin heat insulation pad is connected to the forward cabin frame; The cabin heat insulation pad has a through-hole, the wiring component is disposed in the mounting groove, and the two ends of the wiring hole are respectively located on both sides of the cabin heat insulation pad.

[0023] The technical solution specifies that the vehicle includes an engine compartment heat insulation pad and a front engine compartment frame, with the heat insulation pad connected to the front engine compartment frame, providing a stable assembly foundation for the installation of the wiring harness. The mounting grooves on the heat insulation pad provide dedicated installation positions for the wiring harness, allowing for precise insertion and sealing of the grooves, preventing displacement or loosening, and ensuring sealing and sound absorption effects. The two ends of the wiring holes are located on opposite sides of the heat insulation pad, allowing the wiring harness to enter from one side and exit from the other, facilitating smooth wiring arrangement in different areas of the engine compartment and adapting to the wiring harness installation requirements of vehicles with a dual front bulkhead structure. This design allows the wiring harness structure to be perfectly integrated with the vehicle's engine compartment structure. It utilizes the existing structure of the engine compartment's heat insulation pad, eliminating the need for significant modifications to the engine compartment and reducing vehicle production modification costs. Furthermore, the combination of the wiring harness and the mounting slot compensates for the incompleteness of the small front bulkhead structure caused by traditional pre-drilled holes, further enhancing the integrity and sealing of the engine compartment. At the same time, it allows the wiring harness arrangement to better fit the vehicle structure, improving assembly stability and reliability, and comprehensively optimizing the vehicle's overall performance.

[0024] In some embodiments of this application, the mounting part is a mounting hole; a buckle is provided on the front nacelle frame, and the buckle is used to be inserted into the mounting hole.

[0025] In this technical solution, the mounting section is designed as a mounting hole, and a buckle is installed on the front engine compartment frame. The wiring harness is fixed by inserting the buckle into the mounting hole, making the installation and disassembly of the wiring structure more convenient and efficient. During assembly, simply align the mounting hole of the wiring harness with the buckle on the front engine compartment frame and press it down to complete the fixation, eliminating the need for additional fasteners (such as bolts, screws, etc.), simplifying the assembly process and improving production efficiency. During disassembly, simply pull up the wiring harness to disengage the buckle from the mounting hole, and the wiring harness can be removed, facilitating subsequent maintenance and replacement. The engagement between the buckle and the mounting hole provides excellent connection stability, resisting vibrations generated during vehicle operation, preventing the wiring harness from falling off or shifting, and ensuring the sealing effect of the wiring harness in the mounting slot and the stable arrangement of the wiring harness. At the same time, this fixing method is simple in structure and low in cost, requiring no complex processing on the wiring harness or the front engine compartment frame, further reducing manufacturing costs. Moreover, the engagement between the buckle and the mounting hole does not damage the sealing and sound-absorbing structure of the wiring harness.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments. It should be noted that in the automotive industry, wiring harnesses need to be installed during vehicle production. Especially in some vehicles with a dual front bulkhead structure, the wiring harness in the engine compartment needs to pass through the engine compartment heat insulation pad mounting plate during the layout process. Since the diameter of the engine compartment wiring harness varies among different vehicle configurations, in order to adapt to the installation requirements of various wiring harnesses, existing technologies usually reserve through holes for the engine compartment wiring harness assembly on the engine compartment heat insulation pad mounting plate so that the wiring harness can be smoothly passed through and arranged, ensuring the normal connection and operation of the vehicle's electrical system.

[0031] In the existing technology, the wiring harness through holes reserved on the engine compartment heat insulation pad mounting plate will cause damage to the integrity of the small front bulkhead structure. On the one hand, it will damage the structural sealing of the engine compartment area, thereby affecting the NVH (noise, vibration and harshness) performance of the whole vehicle, and aggravating the transmission of noise and vibration during vehicle operation. On the other hand, the exposed through holes and the messy arrangement of the surrounding wiring harness will seriously affect the aesthetics of the engine compartment interior and will not meet the requirements of the refined design of the overall vehicle appearance and structure.

[0032] Based on this, this application proposes a wiring structure and vehicle. The wiring harness passes through the wiring holes on the engine compartment heat insulation pad by sealing the mounting groove with a wiring component, thus avoiding direct exposure or messy wiring arrangement. Compared to the existing technology's pre-drilled holes, this structure effectively compensates for the integrity deficiencies of the small front bulkhead structure, significantly improves the sealing performance of the engine compartment area, reduces the transmission of noise and vibration during driving, optimizes the overall vehicle NVH performance, and enhances aesthetics.

[0033] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0034] Please refer to all the accompanying drawings. In one schematic embodiment of the wiring structure and vehicle of this application, the wiring structure includes a wiring member 100, which is made of a flexible sound-absorbing material; a wiring hole 200 is provided through the wiring member 100. The wire harness can pass through the wiring member 100 through the wiring hole 200, thereby realizing the arrangement and fixation of the wire harness.

[0035] Furthermore, the wiring harness 100 is used to install in the mounting groove of the naval heat insulation pad and to seal the mounting groove. Since the wiring harness primarily passes through the naval heat insulation pad, this application places the wiring harness 100 on the naval heat insulation pad, eliminating the need for through holes in the pad. The sound-absorbing properties of the wiring harness 100 reduce noise transmission.

[0036] In some embodiments, the wiring structure further includes a mounting section for mounting the wiring member 100 to the forward nacelle frame.

[0037] This application utilizes the aforementioned solution, employing a flexible sound-absorbing wire harness 100 as the wiring structure. This design offers excellent flexibility, adapting to the installation requirements of the engine compartment heat insulation pad mounting slot and achieving a tight seal. Furthermore, its sound-absorbing properties reduce noise transmission paths. The wire harness hole 200 provides a passageway for the wiring harness, preventing direct exposure or cluttered arrangement. The mounting mechanism ensures the wire harness 100 is securely mounted to the front engine compartment frame, guaranteeing structural reliability. Compared to existing solutions with pre-drilled holes, this structure effectively compensates for the integrity deficiencies of the small front bulkhead structure, significantly improves the sealing of the engine compartment area, reduces noise and vibration transmission during driving, and optimizes the overall vehicle NVH (noise, vibration, and harshness) performance. Simultaneously, it allows for a more organized wiring harness arrangement, avoiding exposed and cluttered issues, enhancing the aesthetics of the engine compartment interior, meeting the refined requirements of the overall vehicle structural design, and the flexible material adapts to different installation scenarios, resulting in higher installation convenience.

[0038] In some embodiments, the wire threading member 100 has an inlet side and an outlet side on opposite sides, with the rest being peripheral sides. It is understood that the inlet side and outlet side of the wire threading member 100 are parallel to each other, and its structure is simple and easy to manufacture, such as a rectangular block, trapezoidal block, frustum, etc.

[0039] In some embodiments, the wire hole 200 extends through the inlet and outlet sides; a wire groove 300 extends through one of its peripheral sides, connecting the wire hole 200 to the outside; the wire groove 300 extends through the inlet and outlet sides. This design ensures that the wire groove completely extends through the wire guide 100 along its length, guaranteeing that the wire bundle can pass through the wire groove 300 and enter the wire hole 200.

[0040] During assembly, the wire harness can be quickly inserted into the wire hole 200 through the wire groove 300, eliminating the need for overall threading and reducing operational difficulty. For subsequent maintenance, the wire harness can be easily removed or adjusted through the wire groove 300, reducing disassembly workload. This design retains the sealing and sound-absorbing characteristics of the wire harness structure while solving the problems of cumbersome assembly and inconvenient maintenance associated with traditional wire hole 200 designs. This further enhances the practicality and operability of the wire harness structure, while maintaining the overall structural integrity of the wire harness component 100, ensuring effective sealing of the mounting groove and NVH optimization.

[0041] In some embodiments, multiple through holes 200 are provided, and the number of wire guide grooves 300 is the same as the number of through holes 200 and they are arranged one-to-one. The multiple through holes 200 allow the structure to simultaneously meet the needs of multiple wire harnesses, adapting to complex wire harness layout scenarios in vehicle engine compartments. This avoids tangling and wear problems caused by multiple wire harnesses passing through the same hole, reduces the risk of wire harness short circuits and failures, and improves the reliability of the electrical system. The wire guide grooves 300 correspond one-to-one with the through holes 200, ensuring that each wire harness can be independently assembled and maintained through its dedicated wire guide groove 300. This further optimizes operational convenience. During assembly, wire harnesses with different functions can be inserted into dedicated through holes 200 through their corresponding wire guide grooves 300, achieving classified arrangement of wire harnesses and facilitating subsequent troubleshooting and maintenance. During maintenance, only the wire guide groove 300 corresponding to the target wire harness needs to be operated on, without affecting the normal operation of other wire harnesses. While ensuring sealing, sound absorption, and aesthetics, this design improves the adaptability of the wiring structure to multi-wiring-harness scenarios, making the wiring harness layout more organized and in line with the standardized design requirements of the vehicle's electrical system.

[0042] Preferably, the wire hole 200 is a round hole, because most wire harnesses are circular, and a round wire hole 200 is easier to match with a circular wire harness. Furthermore, round holes are easier to create, reducing manufacturing costs.

[0043] In some embodiments, when there are multiple through holes 200, at least one through hole 200 has a different diameter than the others. This allows the wiring structure to adapt to the needs of wire harnesses with different diameters. Wire harnesses in the vehicle's engine compartment vary in diameter due to different functions. Traditional through holes 200 of uniform diameter either cannot accommodate thicker wire harnesses or leave large gaps for thinner wire harnesses, affecting sealing performance and NVH performance. This design, through through holes 200 of differentiated diameters, allows each wire harness to fit tightly with its corresponding through hole 200. This ensures smooth insertion of thicker wire harnesses while avoiding gaps between thinner wire harnesses and the through holes 200, enhancing sealing performance and further reducing noise transmission. Simultaneously, the differentiated diameter design eliminates the need for additional seals or adapter structures, simplifying the overall design and maintaining the simplicity and low cost advantages of the wiring structure while meeting diverse wire harness adaptation needs.

[0044] Furthermore, when there are multiple threading holes 200, the length directions of the multiple threading holes 200 can be parallel to each other, thereby ensuring that the spacing between any two threading holes 200 is constant, avoiding the situation where two threading holes 200 are too close at a certain position due to different directions of the threading holes 200, thus ensuring the overall structural strength of the threading component 100.

[0045] In some embodiments, the mounting part is a mounting hole 400, which is formed on one of the peripheral sides of the wiring member 100, and the mounting hole 400 and the cable passage 300 are located on different peripheral sides. Due to the material of the wiring member 100, it is not suitable for installing other structures. Therefore, a buckle can be provided on the forward engine compartment frame, which passes through and engages with the mounting hole 400, thus achieving a stable connection between the wiring member 100 and the forward engine compartment frame. At the same time, one side of the mounting hole 400 is necessarily the side of the wiring member 100 used to fit against the forward engine compartment frame. Therefore, after the wiring member 100 is installed, in order to avoid the cable passage 300 being blocked by the forward engine compartment frame, the cable passage 300 and the mounting hole 400 are set on different side walls, avoiding interference when installing the wire harness. At the same time, the layout of different peripheral sides makes the force on the wiring member 100 more even, avoiding structural instability caused by too many openings on one side wall, and making the overall design of the wiring structure more reasonable and compact.

[0046] Understandably, the shape and size of the mounting hole 400 can be determined according to the required clips to ensure stability after installation.

[0047] In another embodiment, the mounting part can be a separate structure, with one end fixed to the wiring member 100 and the other end used to fix to the front cabin frame.

[0048] Specifically, the mounting part can be a clip, which is fixed to the wiring component 100, and the other end is inserted into the forward engine compartment frame. Alternatively, the clip and the wiring component 100 can be detachably connected, and the clip and the forward engine compartment frame can also be detachably connected.

[0049] In a preferred embodiment, the mounting hole 400 communicates with the wire-passing hole 200; the mounting hole 400 is located on the side of the wire-passing hole 200 away from the wire-passing groove 300. The wire-passing component 100 is installed after the front engine compartment frame through the mounting hole 400, and the wire-passing groove 300 is located on the side furthest from the front engine compartment frame, making it easier for manual installation of the wire harness through the wire-passing groove 300 into the wire-passing hole 200. Furthermore, the communication between the mounting hole 400 and the wire-passing hole 200 simplifies the production process and saves production costs. In addition, the mounting hole 400 in this application is a through hole; when the length of the clip connected to it is too long, the excess clip length can extend into the wire-passing hole 200 without affecting the installation of the wire-passing component 100, ensuring that the wire-passing component 100 fits snugly against the front engine compartment frame, enhancing the stability of the wire harness installation, and simultaneously ensuring sealing effect and NVH performance.

[0050] In addition, the mounting hole 400 can be separated from the wiring hole 200 to avoid direct contact between the clips on the front engine compartment frame and the wiring harness inside the wiring hole 200. This effectively prevents the clips from squeezing or abrading the wiring harness, reduces the risk of insulation damage and short circuits caused by contact friction, and ensures the stable operation of the vehicle's electrical system.

[0051] In a preferred embodiment, the wiring component 100 is made of sponge. Sponge, as a typical flexible sound-absorbing material, possesses excellent sound absorption, sealing, and flexibility properties. In terms of sound absorption, the porous structure of the sponge effectively absorbs noise generated during vehicle operation, further blocking the transmission path of noise through the mounting groove and the gap in the wiring harness, significantly improving the overall NVH performance of the vehicle. In terms of sealing, the sponge has good elasticity, allowing it to tightly conform to the inner wall of the mounting groove and the surface of the wiring harness, maximizing the filling of gaps, enhancing the sealing of the engine compartment area, preventing dust and moisture from entering, and protecting the wiring harness and components inside the engine compartment. In terms of flexibility, the sponge is easy to bend and deform, adapting to the complex shape of the mounting groove, reducing installation difficulty. Simultaneously, when the vehicle vibrates during operation, the elasticity of the sponge can buffer the vibration impact on the wiring harness, reducing wear and fatigue damage, and extending the service life of the wiring harness. Compared to other flexible sound-absorbing materials, sponge is lower in cost, widely available, and has a simple processing technology, enabling cost reduction for the entire vehicle while ensuring technical effectiveness.

[0052] In another embodiment, the material of the threading member 100 can be soft rubber, which still has good sound absorption performance and good toughness.

[0053] Furthermore, this application also provides a vehicle, including: a vehicle body and a wiring harness for mounting to the vehicle body, wherein the aforementioned wiring structure is installed on the vehicle body; at least one wire harness passes through the wiring hole 200 of the wiring harness 100. The vehicle employing the aforementioned wiring structure significantly optimizes the overall NVH performance, reduces driving noise and vibration, and improves ride comfort. In terms of safety, the wiring harness is neatly arranged through the wiring hole 200, avoiding exposure, tangling, and wear, reducing the risk of short circuits and malfunctions, ensuring the stable operation of the vehicle's electrical system, and improving driving safety. In terms of aesthetics, the wiring harness 100 seals the mounting slot and neatly arranges the wiring harness, making the interior layout of the engine compartment cleaner and more orderly, meeting the refined requirements of the overall vehicle appearance and structural design. In terms of economy, the wiring structure uses low-cost materials such as sponge, replacing the traditional wire protection box structure, achieving the goal of reducing the cost and weight of the entire vehicle and enhancing the product's market competitiveness. At the same time, the wiring structure has strong adaptability, meeting the wiring harness layout requirements of vehicles with different configurations, enhancing the versatility and flexibility of vehicle production, and reducing manufacturing costs.

[0054] In some embodiments, the system includes a cabin heat insulation pad and a front cabin frame; the cabin heat insulation pad is connected to the front cabin frame; a mounting groove is provided through the cabin heat insulation pad, and a wiring harness 100 is disposed in the mounting groove, with the two ends of the wiring hole 200 located on both sides of the cabin heat insulation pad. The vehicle includes a cabin heat insulation pad and a front cabin frame, with the cabin heat insulation pad connected to the front cabin frame, providing a stable assembly foundation for the installation of the wiring structure. The mounting groove on the cabin heat insulation pad provides a dedicated installation position for the wiring harness 100, allowing it to be precisely embedded and sealed, preventing displacement or loosening, and ensuring sealing and sound absorption effects. The two ends of the wiring hole 200 are located on both sides of the cabin heat insulation pad, allowing the wiring harness to enter from one side of the cabin heat insulation pad and exit from the other side, achieving smooth wiring arrangement in different areas of the cabin and adapting to the wiring harness installation requirements of vehicles with a dual front bulkhead structure. This design allows the wiring harness structure to be perfectly integrated with the vehicle's engine compartment structure. It utilizes the existing structure of the engine compartment insulation pad, eliminating the need for major modifications to the engine compartment and reducing vehicle production modification costs. Furthermore, the cooperation between the wiring harness 100 and the mounting slot compensates for the incompleteness of the small front bulkhead structure caused by traditional pre-drilled holes, further enhancing the integrity and sealing of the engine compartment. At the same time, it allows the wiring harness arrangement to fit the vehicle structure more closely, improving the stability and reliability of assembly and comprehensively optimizing the overall performance of the vehicle.

[0055] In some embodiments, the mounting part is a mounting hole 400; a buckle is provided on the front engine compartment frame, which is used to insert into the mounting hole 400. Designing the mounting part as a mounting hole 400 and providing a buckle on the front engine compartment frame, the wiring harness 100 is fixed by inserting the buckle into the mounting hole 400, making the installation and disassembly of the wiring structure more convenient and efficient. During assembly, simply align the mounting hole 400 of the wiring harness 100 with the buckle on the front engine compartment frame and press it down to complete the fixation, without the need for additional fasteners (such as bolts, screws, etc.), simplifying the assembly process and improving production efficiency; during disassembly, simply pull up the wiring harness 100 gently to disengage the buckle from the mounting hole 400, and the wiring harness 100 can be removed, facilitating subsequent maintenance and replacement. The engagement method between the buckle and the mounting hole 400 provides good connection stability, resisting vibrations generated during vehicle operation, preventing the wiring harness 100 from falling off or shifting, and ensuring the sealing effect of the wiring harness 100 on the mounting groove and the stable arrangement of the wire harness. Meanwhile, this fixing method has a simple structure and low cost, and does not require complex processing on the wiring component 100 or the front engine compartment frame, further reducing the production and manufacturing cost. Moreover, the cooperation between the buckle and the mounting hole 400 will not damage the sealing and sound-absorbing structure of the wiring component 100.
