Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and in particular to a frame-crossing wiring harness bracket. Background Technology

[0002] With the rapid development of the automotive industry, especially the accelerated iteration of new models in the heavy-duty truck sector, vehicle configurations are becoming increasingly sophisticated, leading to a significant increase in the number of sensors, electrical components, and wiring harnesses, resulting in increasingly limited chassis space. As the core connection carrier between the vehicle's electrical and hydraulic / pneumatic systems, the rational layout and reliable fixing of wiring harnesses directly affect the vehicle's safety, functionality, and service life. In most models, wiring harnesses need to traverse the frame flanges to connect to the inner and outer sides of the chassis. Therefore, designing a highly adaptable and reliable constraint structure for wiring harnesses that traverse the frame has become an urgent problem to be solved in the industry.

[0003] To address the issue of wiring harnesses crossing the vehicle frame, Chinese Patent No. CN203103860U discloses a wiring harness constraint structure for automotive chassis. This structure includes an inner guide box and an outer guide box, respectively, securely connected to the vehicle frame on the inner and outer sides. The wiring harness passes through these boxes, and both boxes contain a wiring harness guiding mechanism. This structure adds a guiding mechanism at the point where the wiring harness crosses the vehicle frame, effectively constraining the wiring harness's path and reliably securing it.

[0004] While the aforementioned existing technologies can address the interference issue when wiring harnesses cross the vehicle frame to some extent, they still have the following shortcomings in practical use: First, the structure lacks adaptability to size and space. The separate design of the inner and outer guide boxes requires them to be fixed to both sides of the frame, resulting in a large overall space requirement. This makes it difficult to meet the high-density layout requirements of heavy-duty truck chassis components, easily causing spatial conflicts with surrounding parts and limiting the flexibility of vehicle configuration. Second, the structure lacks reliability and detail protection. The structure mainly relies on the closed structure of the guide boxes for constraint, without a dedicated pull strap positioning mechanism. During vehicle vibration, the pull straps used to bind the wiring harness are prone to displacement or detachment, leading to loosening of the wiring harness. Furthermore, the edges of the guide boxes lack scratch-resistant design, which may scratch the wiring harness sheath due to friction during long-term use, affecting its insulation performance and service life. Third, the structure has limited toughness and fatigue resistance. The inner and outer guide boxes are mostly rigid connection structures, lacking buffer and shock absorption design. Under continuous vibration from complex road conditions, the connection between the guide box and the frame, as well as the structure itself, are prone to fracture due to stress concentration, reducing the stability of the constraint structure. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies, such as large space occupation, poor reliability, and limited applicability, and to provide a chassis-mounted cable harness bracket.

[0006] This utility model is achieved through the following technical solution: a frame-crossing cable harness bracket includes a fixing plate with connecting holes, which are connected to the frame. A frame-crossing mechanism capable of crossing the frame's wing surface is provided on one side of the fixing plate, with the side of the frame-crossing mechanism near the fixing plate connected to the edge of the fixing plate. A cable harness fixing plate for cable routing is connected to the side of the frame-crossing mechanism away from the fixing plate. The cable harness fixing plate has multiple strap fixing grooves for securing straps, and the cable harness fixing plate can fix the position of the cable harness through the straps and strap fixing grooves.

[0007] This invention achieves reliable fixing of the cable harness when it crosses the vehicle frame through the above-described structural design, solving the problem of unreliable cable harness fixing in the prior art. The connection method between the fixing plate and the vehicle frame is simple and effective, adaptable to different frame structures, and has strong versatility. Multiple strap fixing slots are provided, allowing for flexible selection of binding positions according to the actual number and location of the cable harness, improving the convenience and adaptability of fixing, while ensuring the stability of the cable harness during vehicle operation, effectively avoiding problems related to vehicle safety, functionality, and service life caused by loose cable harnesses.

[0008] A further improvement of this utility model is that the climbing frame is a U-shaped plate structure, and the end of the first upright plate on one side of the opening end of the climbing frame is connected to the edge of the fixing plate, and the end of the second upright plate on the other side of the opening end of the climbing frame is connected to the wire harness fixing plate.

[0009] This invention increases the structural strength and stability of the support structure through the aforementioned U-shaped plate structure design. Compared with other structural forms, the U-shaped structure can more effectively disperse stress when crossing the frame wing surface, reducing the risk of structural damage caused by vehicle vibration. At the same time, this structural form is simple, easy to manufacture and install, reduces production costs and installation difficulty, improves production efficiency, and is conducive to large-scale promotion and application.

[0010] A further improvement of this utility model is that the fixing plate is perpendicular to the first upright plate, and the fixing plate is located on the outside of the first upright plate.

[0011] This invention enhances the connection between the fixing plate and the frame through the aforementioned vertical and outer-positioned layout, allowing the entire bracket to be more stably fixed to the frame during vehicle operation, reducing the problem of wiring harness fixation failure caused by loose fixing plate. Simultaneously, this layout optimizes the use of space around the frame, avoids interference with surrounding components, improves the utilization rate of vehicle chassis space, and meets the requirements of high-density layout of heavy-duty truck chassis components.

[0012] A further improvement of this utility model is that the wire harness fixing plate is perpendicular to the second upright plate, and the wire harness fixing plate and the second upright plate are located in the same plane.

[0013] This invention, through its vertical and coplanar design, ensures the effective fixation of the wire harness by the fixing plate, preventing horizontal displacement or wobbling of the wire harness and further improving the reliability of its fixation. Simultaneously, this layout makes the entire bracket structure more compact and rational, reducing the space occupied by the bracket, adapting to situations with limited vehicle chassis space, and enhancing the flexibility of vehicle configuration.

[0014] A further improvement of this utility model is that the length H1 of the wire harness fixing plate is greater than the length H2 of the second upright plate, and the two ends of the wire harness fixing plate extend to the outer sides of the two ends of the second upright plate, respectively.

[0015] This invention increases the number and range of cable harnesses that can be fixed by using the aforementioned longer cable harness fixing plate, improving the adaptability of the bracket to different numbers and layouts of cable harnesses. The extension of both ends to the outer side of the upright plate provides more options for strap binding, further enhancing the stability of the fixation and preventing situations where cable harnesses are concentrated in a certain area, thus ensuring the stable operation of the vehicle's electrical and hydraulic / pneumatic systems.

[0016] A further improvement of this utility model is that one end of the wire harness fixing plate is connected to an inclined wire plate.

[0017] This invention, through the inclined design of the aforementioned guide plate, facilitates the installation and organization of cable bundles, avoiding problems such as tangling and knotting during the introduction of cable bundles, thus improving the efficiency and quality of cable bundle installation. Simultaneously, the guide plate provides a certain degree of protection for the cable bundles, reducing friction between the cable bundles and other components of the support, and extending the service life of the cable bundles.

[0018] A further improvement of this utility model is that the conductor plate is inclined downwards, and the included angle between the wire harness fixing plate and the conductor plate is an obtuse angle.

[0019] This invention optimizes the wiring harness routing direction through the aforementioned downward-sloping, obtuse-angle design, resulting in a more rational wiring harness arrangement and contributing to a cleaner and more orderly overall wiring configuration for the vehicle chassis. Simultaneously, it reduces the possibility of interference with other components due to improper wiring harness routing, thereby improving the safety and stability of vehicle operation.

[0020] A further improvement of this utility model is that both the end of the conductor plate away from the wire harness fixing plate and the end of the wire harness fixing plate away from the conductor plate are provided with rolled edges.

[0021] This invention effectively protects the outer sheath of the cable harness through the aforementioned rolled edge design, preventing damage caused by long-term friction, which would affect the insulation performance and service life of the cable harness. At the same time, the rolled edge increases the strength of the support edge, reduces the possibility of edge deformation and damage, and improves the overall durability of the support.

[0022] A further improvement of this utility model is that multiple pull strap fixing grooves are spaced apart on the top and bottom sides of the wire harness fixing plate and the wire guide plate, and multiple pull strap through holes are provided at the connection between the wire harness fixing plate and the second vertical plate.

[0023] This invention, through its multi-position design of strap fixing grooves and through holes, greatly improves the flexibility and reliability of securing the cable harness. The straps can be secured from different directions and positions according to the actual distribution of the cable harness, ensuring it is firmly fixed in all locations. This effectively prevents the straps from shifting or falling off during vehicle vibrations, thus guaranteeing the stable operation of the cable harness.

[0024] A further improvement of this utility model is that the wire harness fixing plate is located above the fixing plate.

[0025] This invention optimizes the wiring structure of the vehicle chassis by placing the wiring harness fixing plate at the top, making the connection of the wiring harness more convenient, reducing bending and twisting during the connection process, and lowering line loss and the risk of failure. At the same time, this layout also helps to improve the utilization rate of the vehicle chassis space, making the layout of various chassis components more rational and orderly, and improving the overall performance of the vehicle.

[0026] As can be seen from the above technical solutions, the beneficial effects of this utility model are:

[0027] 1. This utility model adopts an integrated structural design, forming a compact and highly adaptable wiring harness constraint solution through the organic combination of a fixing plate, a ramp frame, and a wiring harness fixing plate. Compared with the separate structure of inner and outer guide boxes in the prior art, its volume is significantly reduced, which can better adapt to the layout requirements of heavy truck chassis with limited space and effectively avoid interference with surrounding components. At the same time, compared with the two assembly processes that require the inner and outer guide boxes to be fastened to the frame separately, this utility model can complete the installation in one go through the integrated structure, greatly simplifying the assembly steps; and it is formed from a single steel plate using laser cutting and bending processes, eliminating the need for complex assembly processes and significantly reducing manufacturing costs.

[0028] 2. This utility model, through the rolled edge design on the outer side of the bracket, avoids sharp edges scratching the outer sheath of the wiring harness, solving the wear problem that may exist on the edge of the guide box in the prior art; the specially designed pull strap fixing groove can effectively position the pull strap, preventing it from falling off during vehicle vibration and ensuring that the wiring harness always remains stable. In addition, the U-shaped overpass frame's swivel and bending structure has a certain degree of flexibility, which can buffer the stress caused by vibration and reduce the risk of structural fracture. Compared with the rigid connection structure of the inner and outer guide boxes in the prior art, it has better fatigue resistance.

[0029] 3. This utility model expands the wiring harness laying range and ensures a smooth route by extending the wiring harness fixing plate and transitioning it at an obtuse angle with the conductor plate, thus avoiding damage caused by sharp bends. Compared with the layout conflicts that are easily caused by inner and outer guide boxes occupying the inner and outer spaces of the frame respectively, this utility model, by placing the wiring harness fixing plate above the fixing plate, can make full use of the difference in vertical space of the frame, thereby further reducing spatial interference with surrounding components.

[0035] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0036] Now refer to Figure 1 — Figure 3 The following is a description of a specific embodiment: The present invention provides a frame-crossing cable harness bracket, comprising a fixing plate 1, wherein the fixing plate 1 has a connecting hole 101, and the fixing plate 1 is connected to the frame through the connecting hole 101; a frame-crossing bracket 2 capable of crossing the frame wing surface is provided on one side of the fixing plate 1, and the side of the frame-crossing bracket 2 near the fixing plate 1 is connected to the edge of the fixing plate 1, and a cable harness fixing plate 3 for cable routing is connected to the side of the frame-crossing bracket 2 away from the fixing plate 1; the cable harness fixing plate 3 has multiple strap fixing grooves 301 for binding straps, and the cable harness fixing plate 3 can fix the position of the cable harness through the straps and the strap fixing grooves 301.

[0037] The fixing plate 1 is attached to the inner lower wing surface of the frame and connected to the frame through the connecting hole 101, providing a stable mounting base for the entire bracket. One side of the overpass 2 is connected to the edge of the fixing plate 1, allowing it to overpass the frame wing surface and cross from one side of the frame to the other. The wiring harness fixing plate 3 is connected to the side of the overpass 2 away from the fixing plate 1, providing a fixed position for the wiring harness. By binding the pull strap in the pull strap fixing groove 301, the wiring harness can be securely fixed to the wiring harness fixing plate 3.

[0038] This invention achieves reliable fixing of the wiring harness when it crosses the vehicle frame through the above-described structural design, solving the problem of unreliable wiring harness fixing in the prior art. The connection method between the fixing plate 1 and the vehicle frame is simple and effective, adaptable to different vehicle frame structures, and has strong versatility. Multiple strap fixing slots 301 are provided, allowing for flexible selection of binding positions according to the actual number and location of the wiring harness, improving the convenience and adaptability of fixing, while ensuring the stability of the wiring harness during vehicle operation, effectively avoiding problems related to vehicle safety, functionality, and service life caused by loose wiring harnesses.

[0039] Specifically, refer to Figure 1 and Figure 3 The overpass 2 is a U-shaped plate structure. The U-shaped groove 202 of the overpass 2 is used to overpass the vehicle frame wing surface. The end of the first upright plate 201 on one side of the opening end of the overpass 2 is connected to the edge of the fixing plate 1, and the end of the second upright plate 203 on the other side of the opening end of the overpass 2 is connected to the wire harness fixing plate 3.

[0040] The overpass 2 adopts a U-shaped plate structure, with its U-shaped groove 202 used to overpass the frame wing surface. Specifically, it uses the U-shaped groove 202 to overpass from the inner lower wing surface of the frame to the outer lower wing surface. The uprights closer to the fixing plate 1 are in contact with the inner lower wing surface of the frame, while the uprights farther from the fixing plate 1 are in contact with the outer lower wing surface of the frame. This U-shaped structure allows the overpass 2 to better adapt to the frame shape when crossing the frame wing surface. The uprights on both sides connect to the fixing plate 1 and the wiring harness fixing plate 3 respectively, providing support and connection, ensuring the continuity and stability of the entire support structure.

[0041] This invention increases the structural strength and stability of the support structure through the aforementioned U-shaped plate structure design. Compared with other structural forms, the U-shaped structure can more effectively disperse stress when crossing the frame wing surface, reducing the risk of structural damage caused by vehicle vibration. At the same time, this structural form is simple, easy to manufacture and install, reduces production costs and installation difficulty, improves production efficiency, and is conducive to large-scale promotion and application.

[0042] Specifically, refer to Figure 1 and Figure 3 The fixing plate 1 is perpendicular to the first upright plate 201, and the fixing plate 1 is located outside the first upright plate 201.

[0043] The fixing plate 1 is perpendicular to the upright plate on the corresponding side of the overpass 2 and is located on the outside. This layout makes the connection surface of the fixing plate 1 with the frame more closely fit, and can better withstand various forces from the frame. It also provides a stable support foundation for the overpass 2 and the wiring harness fixing plate 3.

[0044] This invention enhances the robustness of the connection between the fixing plate 1 and the vehicle frame through the aforementioned vertical and outer-positioned layout. This allows the entire bracket to be more stably fixed to the frame during vehicle operation, reducing the risk of wiring harness fixation failure due to loose fixing plate. Simultaneously, this layout optimizes the use of space around the vehicle frame, avoids interference with surrounding components, improves the utilization rate of the vehicle chassis space, and meets the requirements for high-density layout of heavy-duty truck chassis components.

[0045] Specifically, refer to Figure 2 and Figure 3The wire harness fixing plate 3 is perpendicular to the second upright plate 203, and the wire harness fixing plate 3 and the second upright plate 203 are located in the same plane.

[0046] The wire harness fixing plate 3 is perpendicular to the upright plate on the corresponding side of the overpass 2 and is located in the same plane. This design allows the wire harness fixing plate 3 to provide a stable fixing platform for the wire harness in the horizontal direction, and the connection with the overpass 2 is more secure.

[0047] This invention, through its vertical and coplanar design, ensures the effective fixation of the wire harness by the three fixing plates, preventing horizontal displacement or wobbling of the wire harness and further improving the reliability of the wire harness fixation. Simultaneously, this layout makes the entire bracket structure more compact and rational, reducing the space occupied by the bracket, adapting to situations with limited vehicle chassis space, and enhancing the flexibility of vehicle configuration.

[0048] Specifically, refer to Figure 1 and Figure 2 The length H1 of the wire harness fixing plate 3 is greater than the length H2 of the second upright plate 203, and both ends of the wire harness fixing plate 3 extend to the outer sides of both ends of the second upright plate 203.

[0049] The wire harness fixing plate 3 is longer than the vertical plate and extends to the outer sides of both ends of the vertical plate. This design allows the wire harness fixing plate 3 to have a wider fixing area when fixing the wire harness, accommodate more wire harnesses, and can be fixed by pulling and binding from multiple positions.

[0050] This invention increases the number and range of cable harnesses that can be fixed by using the aforementioned longer cable harness fixing plate 3, improving the adaptability of the bracket to different numbers and layouts of cable harnesses. The extension of both ends to the outer side of the upright plate provides more options for strap binding, further enhancing the stability of the fixation and preventing insecure fixing due to cable harnesses being concentrated in a certain area, thus ensuring the stable operation of the vehicle's electrical and hydraulic / pneumatic systems.

[0051] Specifically, refer to Figure 1 and Figure 2 One end of the wire harness fixing plate 3 is connected to an inclined wire guide plate 4.

[0052] An inclined guide plate 4 is connected to one end of the wire harness fixing plate 3. When the wire harness is introduced from one end of the wire harness fixing plate 3, the guide plate 4 can guide the direction of the wire harness, so that it can be arranged more smoothly on the wire harness fixing plate 3.

[0053] This invention, through the inclined arrangement of the guide plate 4, facilitates the installation and organization of the cable bundle, avoiding problems such as tangling and knotting during the introduction of the cable bundle, and improving the efficiency and quality of cable bundle installation. At the same time, the guide plate 4 provides a certain degree of protection for the cable bundle, reducing friction between the cable bundle and other components of the support, and extending the service life of the cable bundle.

[0054] In one embodiment, reference Figure 2 The conductor plate 4 is inclined downwards, and the angle between the wire harness fixing plate 3 and the conductor plate 4 is an obtuse angle.

[0055] The wire guide plate 4 is tilted downwards and forms an obtuse angle with the wire harness fixing plate 3. This design allows the wire guide plate to better guide the wire harness downwards, which meets the actual needs of wiring in most vehicle chassis and facilitates the connection of the wire harness with related components below.

[0056] This invention optimizes the wiring harness routing direction through the aforementioned downward-sloping, obtuse-angle design, resulting in a more rational wiring harness arrangement and contributing to a cleaner and more orderly overall wiring configuration for the vehicle chassis. Simultaneously, it reduces the possibility of interference with other components due to improper wiring harness routing, thereby improving the safety and stability of vehicle operation.

[0057] In one embodiment, reference Figure 2 and Figure 3 Both the end of the conductor plate 4 away from the wire harness fixing plate 3 and the end of the wire harness fixing plate 3 away from the conductor plate 4 are provided with rolled edges 5.

[0058] A rolled edge 5 is provided at the end of the conductor plate 4 away from the wire harness fixing plate 3 and at the end of the wire harness fixing plate 3 away from the conductor plate 4. This structure of the rolled edge 5 can prevent the wire harness from directly contacting the edge of the bracket, reducing the risk of friction and scratches.

[0059] This invention effectively protects the outer sheath of the cable harness through the aforementioned rolled edge design, preventing damage caused by long-term friction, which would affect the insulation performance and service life of the cable harness. At the same time, the rolled edge increases the strength of the support edge, reduces the possibility of edge deformation and damage, and improves the overall durability of the support.

[0060] In one embodiment, reference Figure 1 and Figure 2 Multiple pull strap fixing grooves 301 are spaced apart on the top and bottom sides of the wire harness fixing plate 3 and the wire guide plate 4, and multiple pull strap through holes 302 are provided at the connection between the wire harness fixing plate 3 and the second vertical plate 203.

[0061] Multiple pull strap fixing grooves 301 are spaced apart on the top and bottom sides of the wire harness fixing plate 3 and the conductor plate 4, which can bind and fix the wire harness from multiple directions. The pull strap through hole 302 opened at the connection between the wire harness fixing plate 3 and the upright plate can be used to pass pull straps through, further increasing the selection of pull strap fixing methods and positions.

[0062] This invention, through the design of multiple positions for the pull strap fixing groove 301 and the pull strap through hole 302, greatly improves the flexibility and reliability of fixing the pipeline harness. The pull straps can be tied from different directions and positions according to the actual distribution of the pipeline harness, ensuring that the pipeline harness is firmly fixed in all positions. This effectively prevents the pull straps from shifting or falling off during vehicle vibration, ensuring the stable operation of the pipeline harness.

[0063] In one embodiment, reference Figure 2 and Figure 3 The wire harness fixing plate 3 is located above the fixing plate 1.

[0064] The wiring harness fixing plate 3 is located above the fixing plate 1. This layout allows the wiring harness to be fixed at a higher position after it crosses the frame, which facilitates connection with relevant electrical components or hydraulic / pneumatic components on the frame and is beneficial to the overall wiring layout planning.

[0065] This invention optimizes the wiring structure of the vehicle chassis by positioning the wiring harness fixing plate 3 at the top, making the connection of the wiring harness more convenient, reducing bending and twisting during the connection process, and lowering line loss and the risk of failure. At the same time, this layout also helps to improve the utilization rate of the vehicle chassis space, making the layout of various components of the vehicle chassis more reasonable and orderly, and improving the overall performance of the vehicle.

[0066] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
