Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness connector technology, and in particular to a protective structure for vehicle wiring harness connectors and new energy commercial vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry, new energy commercial vehicles have been widely used in logistics transportation, urban public transportation, and other fields. Compared with traditional fuel-powered commercial vehicles, new energy commercial vehicles adopt a more complex electrical control system, containing a large number of controllers, sensors, and other electronic components. These components need to be connected through various high and low voltage wiring harnesses. Among them, high voltage wiring harnesses, due to carrying a large current, have higher requirements for safety and reliability.

[0003] Currently, the wiring harness layout of new energy commercial vehicles mainly has the following problems:

[0004] For vehicles with bottom-mounted battery packs, a large number of high-voltage wiring harnesses have to be arranged at the bottom of the frame and under the cab. To meet the requirements for wiring and connection, many wiring harness connectors have to be arranged downwards, which exposes the connectors directly to areas that are easily corroded by mud, water, and sand. For vehicles with rear-mounted battery packs, although the main high-voltage wiring harnesses are arranged relatively reasonably, since the controllers are mostly located under the cab, some connectors are still in positions that are easily corroded by mud, water, and sand.

[0005] In harsh operating environments, wiring harness connectors are subjected to long-term impact and erosion from sand, gravel, mud, and water, which can easily lead to malfunctions such as decreased insulation performance, poor contact, and corrosion of metal contact surfaces, seriously affecting the safety and reliability of the vehicle.

[0006] To address the above issues, existing technologies primarily employ two protection methods:

[0007] One option is to add a special protective sleeve to the connector. While this method offers good protection, it suffers from high costs and low assembly efficiency. More inconveniently, if the protective sleeve is damaged and needs replacement, the connector must be removed before the sleeve can be replaced, making maintenance cumbersome. Another option is to use metal materials such as steel plates to make a protective cover. While this method is relatively cheaper, the protective structure is heavy, increasing the overall vehicle weight. In addition, since there is still a gap between the metal protective cover and the connector, its protective effect is relatively limited. Utility Model Content

[0008] This utility model discloses a protective structure for vehicle wiring harness connectors and a new energy commercial vehicle, aiming to solve the technical problems existing in the prior art.

[0009] The present invention adopts the following technical solution:

[0010] In a first aspect, embodiments of this utility model provide a protective structure for a vehicle wiring harness connector, comprising:

[0011] - Protective plate, with wire-through holes on the protective plate;

[0012] - Fixing device for securing the protective plate to the vehicle;

[0013] - A sealing component is provided at the wire passage hole. The sealing component includes a barrier member that covers the wire passage hole and is capable of dynamically and flexibly fitting with the wire harness passing through the wire passage hole.

[0014] As a preferred technical solution, the protective panel comprises a composite material of reinforcing fibers and thermoplastic resin.

[0015] As a preferred technical solution, the reinforcing fiber includes braided fiber, which is arranged in a cross pattern in the transverse and longitudinal directions.

[0016] As a preferred technical solution, the barrier component includes flexible bristles, which are used to block external impurities and form a protective sealing layer, while allowing the wire harness to pass through freely.

[0017] As a preferred technical solution, the flexible bristles are sized to completely cover and seal the wire holes.

[0018] The density of the flexible bristles is configured to maintain an effective seal on the wire hole even when subjected to external forces.

[0019] As a preferred technical solution, the sealing component also includes a substrate that is adapted to the periphery of the wire hole, and flexible bristles are fixed on the substrate.

[0020] As a preferred technical solution, the substrate is detachably connected to the protective plate via fasteners.

[0021] As a preferred technical solution, the fixing device includes a first bracket and a second bracket, and the protective plate is fixed near the controller by the first bracket and the second bracket.

[0022] As a preferred technical solution, the shape of the protective plate is adapted to the placement of the controller.

[0023] Secondly, this utility model embodiment provides a new energy commercial vehicle, characterized in that it includes a vehicle wiring harness connector protection structure as described in any of the preceding claims.

[0024] One embodiment of the above-described utility model has the following advantages or beneficial effects:

[0025] This utility model mainly provides a protective structure for vehicle wiring harness connectors. The protective structure includes a protective plate, a fixing device, and a sealing component. The protective plate is preferably made of CFRT composite material sheet. This material can be cut into any flat shape required for protection. Compared with traditional metal materials, the density of CFRT composite material is only 1.5g / cm², which greatly reduces its weight. At the same time, since CFRT composite material is a standard sheet, it can be cut into the required shape using conventional processing equipment without the need for additional mold investment.

[0026] Furthermore, the barrier component is installed at the cable passage hole of the protective plate, enabling effective protection over a large area. When the wire harness is connected to the cable passage hole, the flexible bristles in the barrier component can maintain real-time protection of the interface under static or dynamic conditions to ensure the protective effect. In addition, the barrier component can be made of aluminum alloy strip brushes, which can be manufactured using a simple thermal cutting process, resulting in lower overall manufacturing costs.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. In the description of this utility model, it should be noted that the term "or" is generally used to include the meaning of "and / or," unless otherwise expressly stated otherwise.

[0035] In the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Existing vehicle wiring harness connectors typically employ a simple open design, making them susceptible to corrosion from external environmental factors such as dust, rain, and foreign objects during vehicle operation. Furthermore, the lack of effective protective measures can lead to short circuits, poor contact, and other malfunctions at the wiring harness connectors, affecting the vehicle's safety performance and lifespan.

[0038] refer to Figure 1 — Figure 4 To address the problems existing in the prior art, this utility model provides a protective structure for a vehicle wiring harness connector. The structure includes a protective plate 10, a fixing device, and a sealing component 20. The fixing device secures the protective plate 10 to the vehicle. The protective plate 10 has a wire-passing hole 11. The sealing component 20 is disposed at the wire-passing hole 11 and mainly includes a barrier component. The barrier component covers the wire-passing hole 11 and can flexibly fit with the wiring harness 42 passing through the wire-passing hole 11, sealing the gap. Through the synergistic effect of the above components, comprehensive protection of the vehicle wiring harness connector can be achieved. In particular, the barrier component has self-adjusting capability, adapting to different specifications of wiring harness 42, ensuring no exposed gaps around the wire-passing hole 11, thereby effectively blocking harmful substances such as high-pressure water flow, mud, and stones. Furthermore, the protective structure provided in this embodiment not only provides protection when the vehicle is stationary, but also maintains a sealed contact with the wiring harness 42 under vibration and bump conditions generated when the vehicle is in motion, thus maintaining a stable protective effect. By achieving continuous protection, the service life of the wiring harness 42 and the connector is significantly improved, the failure rate caused by environmental factors is reduced, and the operational reliability of the vehicle is enhanced.

[0039] In a preferred embodiment, the protective plate 10 employs a composite pressing structure of reinforcing fibers and thermoplastic resin. The reinforcing fibers are woven, arranged in a cross-sectional and longitudinal pattern to form a mesh-like fiber skeleton structure. This woven structure gives the protective plate 10 high strength and toughness in all directions, effectively resisting external impacts.

[0040] In a preferred embodiment, the protective plate 10 is preferably made of CFRT composite material, which is formed by high-temperature and high-pressure composite pressing of woven carbon fiber as reinforcement and thermoplastic resin as matrix. Specifically, CFRT composite material has excellent mechanical properties, with its tensile strength and flexural strength significantly higher than those of ordinary engineering plastics; it also has good corrosion resistance and aging resistance, and can be used for a long time in harsh environments with stable performance; in addition, this material has the characteristics of low density and light weight, which helps to reduce the overall vehicle weight.

[0041] In a preferred embodiment, the shape of the protective plate 10 can be customized according to the installation arrangement of the vehicle controller 41. Specifically, since the CFRT composite material sheet used in the protective plate 10 has good machinability, it can be cut into a shape that matches the arrangement position of the vehicle controller 41 using conventional cutting equipment, so that the protective plate 10 can fully cover the surrounding area of ​​the vehicle controller 41 and provide complete protective space for the wiring harness connector.

[0042] In practical applications, the protective plate 10 can be customized by simple machining processes such as drilling and trimming, based on the specific installation location of the vehicle controller 41, the routing of the wiring harness 42, and the layout characteristics of surrounding components, to ensure that its shape and contour are highly matched with the installation environment. Because CFRT composite material sheets have excellent machinability, rapid and precise shape customization can be achieved without the need for special molds or complex processing techniques, significantly expanding the applicable scenarios for the protective structure.

[0043] In a preferred embodiment, since the vehicle controller 41 is typically installed at the bottom of the vehicle body, in the engine compartment, or in other areas heavily influenced by the environment, the protective plate 10 needs to be designed with appropriate shapes depending on these different installation locations. When the vehicle controller 41 is located at the bottom of the vehicle body, the protective plate 10 can be designed as a regular shape such as a rectangle or trapezoid, with fixing points around its perimeter; when the vehicle controller 41 is installed in the engine compartment, the protective plate 10 may need to be designed as an irregular shape such as an L-shape or U-shape to avoid obstructing other components in the engine compartment.

[0044] In a preferred embodiment, the protective plate 10 can be planar in shape, such as... Figure 2The protective plate 10 can also be designed with folded edges, curved protrusions, or recesses to accommodate space constraints. For example, in confined spaces, bending at the edges of the protective plate 10 can increase structural strength while improving space utilization. When it needs to span multiple planes, the protective plate 10 can be designed as a stepped or multi-layered structure to adapt to complex installation environments. By configuring the specific shape of the protective plate 10 according to the specific scenario, the protective structure can fully adapt to the protection needs of different vehicle models and installation locations.

[0045] In a preferred embodiment, the fixing device employs a dual-support structure, including a first support 31 and a second support 32, for securely mounting the protective plate 10 near the vehicle controller 41. By configuring the dual-support structure, the protective plate 10 can be effectively prevented from shaking or deforming during vehicle operation, ensuring the continuity and reliability of the protective effect.

[0046] Preferably, the positions of the first bracket 31 and the second bracket 32 ​​can be reasonably arranged according to the size and stress conditions of the protective plate 10. Typically, the two brackets are set at different positions on the protective plate 10, forming a multi-point support structure that effectively disperses the force. This support method not only improves the installation stability of the protective plate 10 but also enhances the vibration resistance of the entire protective structure. Especially when the vehicle encounters bumps during driving, the dual-bracket structure can effectively absorb the impact to prevent the protective plate 10 from shifting or deforming.

[0047] In a preferred embodiment, the protective plate 10, the bracket, and the vehicle controller 41 are fixed together by bolts. Specifically, the first bracket 31 and the second bracket 32 ​​are provided with mounting holes at both ends, one of which corresponds to the pre-drilled fixing holes on the protective plate 10, and the other of which corresponds to the existing bolt fixing points on the vehicle controller 41.

[0048] In this embodiment, the installation steps are not specifically limited, and those skilled in the art can freely select and adjust them according to the specific model or structure of the vehicle.

[0049] In a preferred embodiment, the wire-passing holes 11 provided on the protective plate 10 correspond one-to-one with the wire harness plug positions of the vehicle controller 41, so as to ensure that the wire harness 42 can pass smoothly through the protective plate 10 and connect to the vehicle controller 41.

[0050] In a preferred embodiment, the wire through hole 11 can be configured with different structures and shapes according to actual installation requirements. Specifically, the wire through hole 11 can be circular, elliptical, square, or other irregular shapes. When a single wire harness 42 needs to be threaded through, a circular wire through hole 11 that matches the diameter of the wire harness 42 can be used; when multiple wire harnesses 42 need to be threaded through simultaneously, an elliptical or rectangular wire through hole 11 can be used to accommodate the concentrated arrangement of the wire harnesses 42; when the arrangement of the wire harnesses 42 is special, the wire through hole 11 can also be designed with other irregular shapes according to actual needs.

[0051] To effectively seal the wire passage hole 11, the sealing assembly 20 adopts a three-piece structure design consisting of a base 21, a barrier component, and a fastener 23. The shape and size of the base 21 are adapted to the peripheral contour of the wire passage hole 11, accurately covering the area of ​​the wire passage hole 11. The base 21 is detachably connected to the protective plate 10 via the fastener 23, facilitating disassembly and assembly during routine maintenance. When the wire harness 42 needs inspection, the sealing assembly 20 can be removed by disassembling the fastener 23, and reinstalled after maintenance, thus ensuring the integrity of the protective structure. Optionally, the fastener 23 can be a bolt.

[0052] Preferably, the barrier component is configured as flexible bristles 22 and fixedly mounted on the base 21, forming a sealed protective layer in the area of ​​the wire passage hole 11. Because the flexible bristles 22 have good deformability, they can closely conform to the surface of the wire harness 42 while allowing the wire harness 42 to pass freely without causing wear. Furthermore, the flexible bristles 22 can effectively prevent external impurities such as water, mud, and dust from entering, and can adapt to the slight displacement of the wire harness 42 during use.

[0053] In a preferred embodiment, the substrate 21 may be arranged in a strip or ring shape, and the extension direction of the flexible bristles 22 varies accordingly with the shape of the substrate 21.

[0054] When configured as a strip, the base 21 is an integrally formed elongated structure. Its length is consistent with or slightly larger than the diameter or size of the wire hole 11, and the width is determined according to actual installation requirements. Both ends of the base 21 are provided with fixing holes for fasteners 23. The base 21 is firmly installed on the protective plate 10 by the fasteners 23, thereby effectively covering the wire hole 11. At this time, the flexible bristles 22 extend along the width direction of the base 21, that is, the bristles are arranged perpendicular to the length direction of the base 21. This arrangement allows the bristles to evenly cover the area of ​​the wire hole 11, forming a dense protective layer that effectively blocks the intrusion of external impurities.

[0055] When configured in a ring shape, the base 21 adopts a closed ring structure, and its outer contour matches the outer contour of the wire hole 11. Multiple fixing holes for fastener 23 are distributed circumferentially on the ring-shaped base 21, and the base 21 is fixed to the protective plate 10 by the fastener 23. At this time, the flexible bristles 22 extend radially inward from the base 21, that is, the flexible bristles 22 are arranged to extend from the edge of the ring-shaped base 21 towards the center.

[0056] Regardless of whether a strip or ring configuration is used, the thickness and material of the substrate 21 should ensure sufficient strength and rigidity to withstand various stresses during installation and use. At the same time, the surface of the substrate 21 should have appropriate flatness to ensure a good fit with the protective plate 10 and avoid omissions or loosening.

[0057] Preferably, the size and density configuration of the flexible bristles 22 need to meet specific requirements. Specifically, the size configuration of the flexible bristles 22 is such that it can completely cover and seal the wire hole 11, and its density configuration is such that it can still maintain an effective seal on the wire hole 11 when subjected to external force.

[0058] In a preferred embodiment, when the substrate 21 is configured as a strip and is provided only on one side of the wire hole 11, the length of the flexible bristles 22 should be greater than the width of the wire hole 11 so that it can completely cover the entire opening area of ​​the wire hole 11, ensuring that there are no exposed gaps.

[0059] like Figures 3-4 In another preferred embodiment, when the substrate 21 is configured as a strip and is arranged opposite to each other on both sides of the wire passage hole 11, the length of the flexible bristles 22 should be greater than half the width of the wire passage hole 11, so that the flexible bristles 22 extending opposite to each other on both sides can jointly cover the entire opening area of ​​the wire passage hole 11, ensuring no exposed gaps. At this time, when the wire bundle 42 passes through the flexible bristles 22, any gaps that may appear will be sealed by the flexible bristles 22 on the other side to ensure sealing. Since the wire passage hole 11 may be irregular in shape, the bristle length in different areas should match the contour of the wire passage hole 11 at that location to ensure that there are no dead corners at the edges.

[0060] When the substrate 21 is configured in a ring shape, the length of the flexible bristles 22 should be greater than the distance between the inner side of the substrate 21 and the center of the wire hole 11, so that it can completely cover the area from the inner ring of the substrate 21 to the center of the wire hole 11. Since the wire hole 11 may have an irregular shape, the bristle lengths at different positions on the circumference of the annular substrate 21 should be adapted to the distance from the edge of the wire hole 11 to the inner ring of the substrate 21 at the corresponding positions, ensuring that the bristles can fully cover all parts of the wire hole 11 and avoid sealing blind spots. This radially inward bristle arrangement allows the bristles to converge evenly from all directions of the annular substrate 21 to the wire hole 11 area, forming a complete sealing and protective layer.

[0061] Regarding the bristle density configuration, the number of bristles per square centimeter should be sufficiently dense to form an effective barrier layer between adjacent bristles. Even when deformed under external force, the bristles can still maintain sufficient contact to maintain a continuous sealing effect on the wire passage 11. When the wire harness 42 passes through the bristle area, the bristles can adaptively deform and adhere tightly to the surface of the wire harness 42, forming a dynamic sealing effect.

[0062] By configuring the flexible bristles 22 with appropriate sizes and densities, the flexible bristles 22 can form a reliable seal on the wire hole 11 under static conditions and maintain the sealing effect under dynamic conditions (such as vehicle vibration or movement of the wiring harness 42), thereby achieving continuous and effective protection for the vehicle controller 41. At the same time, the reasonable bristle configuration also ensures that the wiring harness 42 will not encounter excessive resistance when passing through, facilitating installation and maintenance operations.

[0063] In a preferred embodiment, both the barrier component and the base 21 are preferably configured as aluminum alloy strip brushes, wherein the base 21 is made of aluminum alloy profile, and the flexible bristles 22 are fixed in the groove structure of the base 21 by mechanical pressing. Specifically, the aluminum alloy profile has a fixing groove along its length for installing the flexible bristles 22, and the roots of the flexible bristles 22 are fixed in the groove by binding with metal wire to form a strong integrated structure.

[0064] Since aluminum alloy profiles are inherently strip-shaped, the substrate 21 of the aluminum alloy strip brush is preferably configured as a strip to facilitate manufacturing through processes such as extrusion molding, avoiding custom mold making and thus reducing production difficulty and cost. Simultaneously, the strip structure also facilitates the creation of fixing grooves, simplifying the bristle installation process and improving production efficiency. Furthermore, aluminum alloy material is lightweight, high-strength, and corrosion-resistant, meeting the product's usage requirements in various environments.

[0065] By configuring an integrated aluminum alloy strip brush structure, the overall strength and stability of the barrier components are improved. Furthermore, the mechanical pressing connection method avoids the use of adhesives or other potentially aging connection methods, extending the product's lifespan. At the same time, the standardized aluminum alloy profiles facilitate mass production, helping to reduce manufacturing costs.

[0066] Compared with the prior art, the protective structure provided by this utility model embodiment, by setting a barrier component at the wire passage hole 11 of the protective plate 10 and sealing the wire passage hole 11 with flexible bristles 22, can effectively prevent external impurities from entering the vehicle controller 41 through the wire passage hole 11, and facilitates the installation and maintenance of the wiring harness 42. In particular, the flexible bristles 22 have the characteristic of self-adaptive deformation, which can maintain a good sealing effect on the wire passage hole 11 under both static and dynamic conditions. The protective plate 10 is preferably made of CFRT composite material sheet, which can be cut into any flat shape required according to the protection requirements. Compared with traditional metal materials, the density of CFRT composite material is only 1.5g / cm², which greatly reduces its own weight. At the same time, since CFRT composite material is a standard sheet, it can be cut into the required shape with only conventional processing equipment, without the need for additional mold investment.

[0067] Through the above technical solution, the protective structure provided by this utility model embodiment can achieve reliable protection for the vehicle controller 41, and has the advantages of simple structure, light weight, convenient installation and good maintainability, and is suitable for the protection needs of various vehicle controllers 41.

[0068] Furthermore, this utility model embodiment also provides a new energy commercial vehicle, wherein the vehicle controller 41 of the new energy commercial vehicle is equipped with the vehicle wiring harness plug interface protection structure described in the above embodiment.
