Description

Technical Field

[0001] This utility model relates to the field of truck frame wiring harness fixing technology, and in particular to a truck frame built-in wiring harness integrated groove structure. Background Technology

[0002] Currently, the mainstream fixing structure for truck frame wiring harnesses revolves around the design of "external additional constraints." The core form is to directly fix the wiring harness to the outside of the frame beam using cable ties, external brackets, or corrugated tubing. The advantage of this structure is its simple design and low initial cost, which can meet basic fixing requirements. However, under long-term heavy loads, complex road conditions (such as dirt roads in mining areas and mountain roads), and high-frequency vibration conditions, it exposes multiple technical defects, as follows: Firstly, disassembly and maintenance are inconvenient; cable ties are semi-permanent connections, requiring cutting for maintenance and cannot be reused; external brackets require removing multiple bolts to open; corrugated pipes need to be pre-cut, and additional wiring harnesses require destructive disassembly, which can easily damage components.

[0003] Secondly, the reliability of the fixed position is poor; the chassis vibrates frequently during truck operation, the cable ties are prone to aging and breakage under temperature changes, and the gap between the corrugated pipe and the clamp can cause displacement and wear, all of which may damage the insulation layer of the wire harness.

[0004] Thirdly, the protection and functions are insufficient; the cable ties are not protective, and the wire harness is easily scratched by gravel and welding spatter; the corrugated pipe has poor heat dissipation, and the heat accumulation of the wire harness accelerates the aging of the insulation; in addition, there is no zoning design, and the wire harnesses of multiple systems are mixed and arranged, making it difficult to troubleshoot.

[0005] Fourth, low integration and space occupation; traditional structures are all external attachments, occupying chassis space; with the development of intelligent and new energy trucks, the number of components such as battery packs and radars has increased, the wiring harness layout path has been forced to be extended, affecting signal stability and increasing the difficulty of overall vehicle design. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide an integrated groove structure for the wiring harness built into the truck frame, which solves the problem of inconvenient disassembly and maintenance of the traditional external fixing structure for the wiring harness of the truck frame.

[0007] The technical solution of this utility model is as follows: The truck frame has a built-in integrated wiring harness channel structure, including a U-shaped frame beam. The frame beam has a U-shaped wiring channel inside, which extends along the length of the frame beam and the openings of the two are facing each other. By embedding the wiring channel inside the frame beam, the disadvantages of traditional external fixing structures, such as occupying additional chassis space and being susceptible to external environmental interference, are avoided. After installation, the opening end of the wiring channel fits against the inner sidewall of the frame beam to form a wire passage, providing a closed space for the wiring harness. Dividing rods are spaced along the length of the side wall of the frame beam. The dividing rods extend along the opening direction of the frame beam and pass through the wiring channel and the wire trough. The dividing rods divide the wiring channel into an upper channel and a lower channel. The wire trough can slide horizontally along the dividing rods. The dividing rods realize the upper and lower partitioning of the wiring channel, which facilitates the classification and arrangement of different types of wire harnesses (such as power wire harnesses and signal wire harnesses), and also provide sliding support for the wire trough. The dividing rod section through the wire trough is equipped with fasteners for fixing the position of the wire trough during installation and use, which can adapt to different needs of wire harness installation and long-term fixation. The upper end face of the wire groove forms an upper mounting gap with the upper end face inside the vehicle frame beam, and the lower end face of the wire groove forms a lower mounting gap with the lower end face inside the vehicle frame beam. When the wire groove is located in the end area of ​​the separator bar away from the vehicle frame beam, there is a vertical gap between the open end of the wire groove and the side wall of the vehicle frame beam. The vertical gap and the upper mounting gap are connected to form an upper mounting channel, and the vertical gap and the lower mounting gap are connected to form a lower mounting channel. The mounting channel can be flexibly formed by sliding and adjusting the position of the wire groove.

[0008] Furthermore, the wire trough includes an upper plate, a lower plate, and a connecting plate that connects the two vertically. The free ends of the upper plate and the lower plate are integrally extended with C-shaped limiting plates towards the inner wall of the wire trough. The two limiting plates are symmetrically arranged, and the end faces of the free ends of the two limiting plates face away from the inner wall of the wire trough and are perpendicular to the upper plate and the lower plate. The limiting plates can initially limit the wire harness that passes through the wire trough during installation, and the C-shaped structure can avoid scratching the insulation layer of the wire harness. Multiple elongated heat dissipation holes are arrayed along the length of the upper plate, the lower plate, and the connecting plate.

[0009] Furthermore, the separator rod includes a connecting rod and an octagonal rod head. The end region of the connecting rod away from the frame beam is provided with a threaded section. The length of the threaded section is not less than the width of the vertical gap. The threaded section can adapt to the sliding distance of the groove along the connecting rod. The frame beam and the cable tray have corresponding through holes. The connecting rod passes through the through holes of the U-shaped frame beam and the cable tray in sequence and is screwed with a nut. The octagonal rod head is attached to the side of the frame beam away from the cable tray.

[0010] Furthermore, a silicone deformation component is fitted around the outer periphery of the separator rod located between the side wall of the frame beam and the side wall of the wire groove. The deformation component includes a left connecting cylinder and a right connecting cylinder arranged at intervals along the axis of the separator rod. The two are connected by an arc-shaped cylinder. The axes of the left connecting cylinder, the right connecting cylinder and the arc-shaped cylinder are collinear. The arc-shaped cylinder and the separator rod form a deformation cavity. When the groove is located at the end of the separator bar away from the frame beam, i.e., in the initial state before the deformation component has deformed, the free end of the left connecting cylinder abuts against the inner wall of the frame beam, and the free end of the right connecting cylinder abuts against the inner wall of the groove.

[0011] Furthermore, the arc-shaped cylinder is teardrop-shaped, with the tip of the teardrop facing the inner wall of the wire groove. The teardrop-shaped structure allows the arc-shaped cylinder to guide the wire harness through its own slope in the initial state, assisting the wire harness in returning to the wire passage. The wall thickness of the arc-shaped cylinder near the left connecting cylinder is greater than that near the right connecting cylinder and changes linearly. The gradual change in wall thickness ensures that the arc-shaped cylinder can deform in an orderly manner when compressed, preferentially starting to deform from the thinner side, avoiding irregular deformation that could damage the wire harness, while ensuring that the gap can be filled evenly after deformation, thus enhancing the reliability of the wire harness fixation.

[0012] Furthermore, at least one annular guide groove is provided at the connection between the arc-shaped cylinder and the left connecting cylinder and the right connecting cylinder. The guide groove can guide the deformation direction of the arc-shaped cylinder, so that the arc-shaped cylinder deforms along a preset path during extrusion. The outer wall of the arc-shaped cylinder is provided with a guide rib group along its extension direction. The guide rib group includes multiple strip-shaped guide ribs distributed at intervals along the circumference of the arc-shaped cylinder. The guide rib group can enhance the regularity of the deformation of the arc-shaped cylinder, improve the contact stability between the arc-shaped cylinder and the wire harness after deformation, reduce the relative displacement between the wire harness and the arc-shaped cylinder during vibration, and further ensure the wire harness fixing effect.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model integrates a U-shaped wire trough into a U-shaped vehicle frame beam. The connecting rod of the separator has a threaded section at its end away from the vehicle frame beam, and the wire trough can slide along the connecting rod. It works in conjunction with the upper mounting gap formed by the upper end face of the wire trough and the upper inner end face of the vehicle frame beam, the lower mounting gap formed by the lower end face of the wire trough and the lower inner end face of the vehicle frame beam, and the vertical gap formed when the wire trough is located in the area of ​​the separator away from the end face of the vehicle frame beam. The vertical gap and the upper and lower mounting gaps are connected to form upper and lower mounting channels, respectively. Unlike traditional methods, there is no need to cut cable ties, corrugated pipes, or remove multiple bolts from external brackets. The wire trough can be slid by simply loosening / tightening the nut on the threaded section of the separator, which allows for the installation, addition, or maintenance of wire harnesses.

[0014] 2. This utility model uses a silicone deformation component fitted around the outer periphery of the separator between the vehicle frame beam and the wire trough. The arc-shaped cylinder of the deformation component is teardrop-shaped and its wall thickness gradually changes linearly from the left connecting cylinder to the right connecting cylinder. When the wire trough slides along the separator towards the vehicle frame beam, the left connecting cylinder abuts against the inner wall of the vehicle frame beam and the right connecting cylinder abuts against the inner wall of the wire trough. After being squeezed, the arc-shaped cylinder deforms in an orderly manner along the preset path of the guide groove. The guide rib group enhances the regularity of deformation, fully fills the gap, and avoids the displacement and wear of the wire harness caused by truck vibration. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-5As shown, the truck frame has an integrated wiring harness channel structure, including a U-shaped frame beam 1. Inside the frame beam 1 is a U-shaped wiring channel 2, which extends along the length of the frame beam 1 with its openings facing each other. By embedding the wiring channel 2 inside the frame beam 1, the drawbacks of traditional external fixing structures—such as occupying additional chassis space and being susceptible to external environmental interference—are avoided. The opening end of the wiring channel 2 fits snugly against the inner sidewall of the frame beam 1 after installation, forming a wiring channel 3, providing a closed space for the wiring harness. Multiple dividing rods 4 are spaced along the length of the sidewall of the frame beam 1. These dividing rods extend along the opening direction of the frame beam 1 and penetrate the wiring channel 3 and the wiring channel 2, dividing the wiring channel 3 into an upper channel 3-1 and a lower channel 3-2. The wiring channel 2 can slide horizontally along the dividing rods 4, thus enabling the wiring to pass through. The upper and lower partitions of channel 3 facilitate the classified arrangement of different types of wire harnesses (such as power wire harnesses and signal wire harnesses) and provide sliding support for wire trough 2. The partition rod 4 has fasteners on the partition rod section passing through wire trough 2 to fix the position of wire trough 2 during installation and use, adapting to different needs of wire harness installation and long-term fixation. The upper end face of wire trough 2 forms an upper installation gap 5 with the upper end face inside the frame beam 1, and the lower end face of wire trough 2 forms a lower installation gap 6 with the lower end face inside the frame beam 1. When wire trough 2 is located in the end area of ​​partition rod 4 away from frame beam 1, there is a vertical gap 7 between the open end of wire trough 2 and the side wall of frame beam 1. The vertical gap 7 and the upper installation gap 5 are connected to form an upper installation channel, and the vertical gap 7 and the lower installation gap 6 are connected to form a lower installation channel. The installation channel can be flexibly formed by sliding and adjusting the position of wire trough 2. Furthermore, the cable tray 2 includes an upper plate, a lower plate, and a connecting plate that connects the two vertically. The free ends of the upper plate and the lower plate extend integrally with C-shaped limiting plates 2-1 towards the inner wall of the cable tray 2. The two limiting plates 2-1 are symmetrically arranged, and the free end faces of the two limiting plates 2-1 face away from the inner wall of the cable tray 2 and are perpendicular to the upper plate and the lower plate. The limiting plates 2-1 can initially limit the wire harness that passes through the cable tray 2 during installation, and the C-shaped structure can avoid scratching the insulation layer of the wire harness. Multiple elongated heat dissipation holes 2-2 are arrayed along the length of the upper plate, the lower plate, and the connecting plate. Furthermore, the separator 4 includes a connecting rod 4-1 and an octagonal rod head. The end region of the connecting rod 4-1 away from the frame beam 1 is provided with a threaded section. The length of the threaded section is not less than the width of the vertical gap 7. The threaded section can adapt to the sliding distance of the wire groove 2 along the connecting rod 4-1. The frame beam 1 and the wire groove 2 are respectively provided with through holes. The connecting rod 4-1 passes through the through holes of the U-shaped frame beam 1 and the wire groove 2 in sequence and is screwed with a nut 4-2. The octagonal rod head is attached to the side of the frame beam 1 away from the wire groove 2.Furthermore, a silicone deformable element 8 is fitted around the outer periphery of the separator rod 4 located between the side wall of the frame beam 1 and the side wall of the wire groove 2. The deformable element 8 includes a left connecting cylinder 8-1 and a right connecting cylinder 8-2 arranged at intervals along the axis of the separator rod 4. The two are connected by an arc-shaped cylinder 8-3. The axes of the left connecting cylinder 8-1, the right connecting cylinder 8-2 and the arc-shaped cylinder 8-3 are collinear, and the arc-shaped cylinder 8-3 and the separator rod 4 form a deformable cavity. When the wire groove 2 is located in the end area of ​​the separator rod 4 away from the frame beam 1, that is, in the initial state where the deformable element 8 has not deformed, the free end of the left connecting cylinder 8-1 abuts against the inner side wall of the frame beam 1, and the free end of the right connecting cylinder 8-2 abuts against the inner side wall of the wire groove 2. Furthermore, the arc-shaped cylinder 8-3 is teardrop-shaped, with the tip of the teardrop facing the inner wall of the wire groove 2. The teardrop-shaped structure allows the arc-shaped cylinder 8-3 to guide the wire harness through its own slope in the initial state, assisting the wire harness in returning to the wire channel 3. The wall thickness of the arc-shaped cylinder 8-3 near the left connecting cylinder 8-1 is greater than that near the right connecting cylinder 8-2 and changes linearly. The gradual change in wall thickness ensures that the arc-shaped cylinder 8-3 can deform in an orderly manner when it is squeezed, preferentially starting the deformation from the thinner side, avoiding irregular deformation that could damage the wire harness, while ensuring that the gap can be filled evenly after deformation, thus enhancing the reliability of the wire harness fixation. Furthermore, at least one annular guide groove 8-4 is provided at the connection between the arc-shaped cylinder 8-3 and the left connecting cylinder 8-1 and the right connecting cylinder 8-2. The guide groove 8-4 can guide the deformation direction of the arc-shaped cylinder 8-3, so that the arc-shaped cylinder 8-3 deforms along a preset path during extrusion. The outer wall of the arc-shaped cylinder 8-3 is provided with a guide rib group protruding along its extension direction. The guide rib group includes multiple strip-shaped guide ribs 8-3.1 distributed circumferentially along the arc-shaped cylinder 8-3. The guide rib group can enhance the regularity of the deformation of the arc-shaped cylinder 8-3, and at the same time improve the contact stability between the arc-shaped cylinder 8-3 and the wire harness after deformation, reduce the relative displacement between the wire harness and the arc-shaped cylinder 8-3 during vibration, and further ensure the wire harness fixing effect.

[0023] Working principle of this utility model: 1. Component Pre-assembly and Positioning: First, insert the connecting rod 4-1 of the separator rod 4 through the outside of the frame beam 1, so that the octagonal rod head fits against the outside of the frame beam 1 to achieve positioning; then, install the deformable part 8 on the section of the connecting rod 4-1 located inside the frame beam 1, ensuring that the left connecting cylinder 8-1 of the deformable part 8 abuts against the inner wall of the frame beam 1, and that the teardrop-shaped tip of the arc-shaped cylinder 8-3 faces away from the frame beam 1; then, adjust the opening direction of the wire groove 2 to face the opening of the frame beam 1, so that the through hole of the wire groove 2... Align the free end of the connecting rod 4-1 and push it in until the inner wall of the wire trough 2 abuts against the right connecting cylinder 8-2 of the deformable part 8. At this time, both ends of the deformable part 8 are respectively attached to the inner wall of the frame beam 1 and the wire trough 2. Finally, screw on the nut 4-2 to complete the initial fixation. At this time, the wire trough 2 is located in the end area of ​​the separator rod 4. Its open end forms a vertical gap 7 with the side wall of the frame beam 1, which is connected with the upper installation gap 5 and the lower installation gap 6 to form the upper installation channel and the lower installation channel, which are reserved for the wire harness to pass through.

[0024] 2. Wire harness classification and installation: Different types of wire harnesses (such as power wire harnesses and signal wire harnesses) are placed into the upper channel 3-1 and lower channel 3-2 of the wiring channel 3 through the upper and lower installation channels. During the wiring process, the C-shaped limiting plate 2-1 of the wire groove 2 provides initial constraint on the wire harness to prevent it from slipping. At the same time, the C-shaped structure prevents scratches on the insulation layer. The slope of the teardrop-shaped arc cylinder 8-3 of the deformation component 8 guides the wire harness and helps it to be placed in the corresponding channel section. 3. Final Fixing and Wire Harness Locking: Use a wrench or other tools to fix the octagonal rod head at one end, then tighten the nut 4-2, causing the wire groove 2 to slide along the separator rod 4 toward the frame beam 1 until the open end of the wire groove 2 is in contact with the inner wall of the frame beam 1; during the sliding process, the deformable part 8 is squeezed, and the arc-shaped cylinder 8-3 deforms along the preset path under the action of the guide groove 8-4. Because the wall thickness gradually changes linearly from left to right, the thinner right part deforms first and shrinks toward the deformation cavity, which, together with the guide rib group, ensures regular deformation; finally, the deformed arc-shaped cylinder 8-3 fills the gap and tightly fixes the wire harness in the wire passage 3.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
