Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness technology, specifically to an automotive door wiring harness arrangement device. Background Technology

[0002] With the rapid advancement of automotive technology and the increasing number of onboard electrical devices, wiring harnesses are playing an increasingly important role. Among these, the number of wiring harnesses on car doors is also growing, and their condition directly affects the normal operation of the entire vehicle, thus impacting its performance. Compared to other automotive wiring harnesses, door wiring harnesses have a unique characteristic: their position changes as the door opens and closes, making them prone to damage during use.

[0003] A search revealed Chinese Patent Publication No. CN210591716U, which discloses a door wiring harness arrangement device, belonging to the field of automotive parts. This device hinges the butterfly door and side panel of the vehicle. It includes a door connecting part and a side panel connecting part, which are fixedly connected to the door and side panel respectively. The extensions of the door connecting part and the side panel connecting part away from the fixed connection point are movably connected to form a link segment. A wiring groove is provided on one side of the link segment. Holes adapted to the wiring groove are formed on the door connecting part and the side panel connecting part. The wiring harness passes through the hole on the door connecting part, exits through the wiring groove, and enters the hole in the side panel connecting part, thus arranging the butterfly door wiring harness. This solution is suitable for butterfly door wiring harness arrangement, offering a convenient, practical, and highly adaptable arrangement method.

[0004] Existing automotive door wiring harness arrangement devices cannot effectively organize the wiring during use. When multiple wires are installed in a crisscross pattern, they become messy and affect the installation of door parts. Furthermore, the change in wire length when the door is opened or closed can easily pull on the connecting wires, causing damage to the wire connection points and wear at the bending points. Therefore, an automotive door wiring harness arrangement device is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automotive door wiring harness arrangement device, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automotive door wiring harness arrangement device, comprising an installation plate, a fixed wire groove fixedly connected to the surface of the installation plate, wire pressing mechanisms provided on both sides of the fixed wire groove, a sorting groove fixedly connected to the surface of the installation plate, the wire pressing mechanisms located inside the sorting groove, a wire splitting mechanism bolted to the surface of the installation plate, a wrapping cage rotatably connected to the surface of the installation plate, a bundled conduit provided inside the wrapping cage, a connecting line provided inside the bundled conduit, the connecting line passing through the fixed wire groove and under the wire pressing mechanism, a wiring bracket fixedly connected to the surface of the installation plate, one end of the bundled conduit fixedly connected to the installation plate, the other end slidably connected to the wiring bracket, and a traction mechanism rotatably connected to the free end of the wrapping cage for pulling the wrapping cage to rotate.

The bundled pipe is S-shaped and wound around the outside of the first and second rotating shafts. Both the upper and lower ends of the first and second rotating shafts are provided with conduit cover plates. Both ends of the upper and lower sets of conduit cover plates are provided with cover rods. The cover rods wrap around the outside of the bundled pipe and are used to push the bundled pipe to prevent it from slipping off the outside of the second rotating shaft when the packaging cage rotates. A rocker plate is fixedly connected to the lower conduit cover plate near the second rotating shaft. The rocker plate is slidably connected to the installation arrangement plate.

[0008] Preferably, the cable routing bracket includes a positioning support plate, a guide rod is fixedly connected to the surface of the positioning support plate, a door connecting plate is fixedly connected to the end of the guide rod away from the positioning support plate, a limit strip is fixedly connected to the door connecting plate, and the limit strip is sleeved on the outside of the traction mechanism for limiting the position.

[0009] Preferably, the bundled pipe is a bendable circular pipe, and a conversion joint is connected to the end face of the bundled pipe. The conversion joint disperses the connecting lines that form a circular cross-section inside the bundled pipe into long strips. One end of the bundled pipe near the conversion joint is fixedly connected to the installation plate, and a traction ring is fixedly connected to the outer side of the other end of the bundled pipe. The traction ring slides on the surface of the guide rod.

[0010] Preferably, the traction mechanism includes a rocker column, which is rotatably connected to the surface of a rocker plate. A traction line is fixedly connected to the surface of the rocker column, and the traction line passes through a limiting strip. A return spring is sleeved on the outside of the traction line, and a limiting plate is provided on the end face of the return spring. The limiting plate is fixedly connected to the surface of the mounting plate, and the return spring is located between the limiting plate and the rocker column. The traction line passes through the limiting plate.

[0011] Preferably, the branching mechanism includes a branching frame, which is connected to the mounting plate by bolts. The branching frame is generally square in shape. A pad is provided on the bottom surface of the inner side of the branching frame. Grooves are arranged in an array on the surface of the pad. A guide groove is opened at the upper end of the branching frame. A positioning block is slidably connected to the inner side of the guide groove. A tightening through hole groove is opened on the upper end face of the branching frame. A positioning bolt is threaded to the end face of the positioning block and passes through the inner side of the tightening through hole groove.

[0012] Preferably, the fixed wire trough includes a wire trough frame, a wire trough pressure plate is slidably connected to the upper end of the inner side of the wire trough frame, an adjusting screw is threadedly connected to the upper end of the wire trough frame, and the bottom end of the adjusting screw is rotatably connected to the wire trough pressure plate.

[0013] Preferably, the pressing mechanism includes a pressing frame, which is rotatably connected to the wire trough frame. Pressing rods are fixedly connected to both sides of the wire trough frame.

[0014] Preferably, a groove is provided above the sorting groove, and the wire pressing mechanism can press the connecting wire into the groove above the sorting groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This automotive door wiring harness arrangement device, by setting a fixed wire groove that can press and fix the connected wires, makes it easier for the two ends of the wires to be connected to the control box. By setting a wire pressing mechanism, the connected wires can be pressed and organized into the inner side of the organizing groove. By setting a wire branching mechanism, the wires connected at various positions on the inside of the door can be fixed and organized, making the wiring arrangement more reasonable and preventing the door installation from being interfered with by the wiring. It achieves the effect of organizing and fixing the wiring and solves the problem of wiring crossing affecting the installation of door parts.

[0017] 2. This automotive door wiring harness arrangement device, by setting a rotatable cage, allows the second rotating shaft to rotate around the first rotating shaft. This allows the bundled tubes surrounding the first and second rotating shafts to change length as the cage rotates, thereby addressing the difference in wire length when the door is opened. When the door is opened, the bundled tubes wrapped inside the cage can actively rotate and extend, preventing the connected wires inside the bundled tubes from being pulled. This achieves the effect of actively extending the bundled tubes to compensate for the difference in wire length when the door is opened, solving the problem that the change in wire length when the door is opened can easily pull on the connected wires and cause damage to the wire connection positions.

[0018] 3. This automotive door wiring harness arrangement device connects the traction wire to the door frame and is fixedly connected to the door by an installation plate. When the door is opened, the traction wire is pulled, causing the bundled cage to rotate. This coordinates with the door opening to deliver the bundled pipe, allowing the bundled pipe to slide along the guide rod when the door is open, thus avoiding the problem of wire bending and wear caused by the door opening and closing.

[0032] like Figure 1-8 As shown, an automotive door wiring harness arrangement device includes a mounting plate 1. A fixed wire trough 2 is fixedly connected to the surface of the mounting plate 1. The fixed wire trough 2 includes a wire trough frame 21. A wire trough pressure plate 22 is slidably connected to the upper end of the inner side of the wire trough frame 21. An adjusting screw 23 is threadedly connected to the upper end of the wire trough frame 21. The bottom end of the adjusting screw 23 is rotatably connected to the wire trough pressure plate 22 to fix the wire trough 2. By setting the wire trough frame 21, the wiring inside the door panel can be gathered and organized, making it convenient to bundle scattered wiring. By setting the wire trough pressure plate 22, whose height can be adjusted by the adjusting screw 23, the wire trough pressure plate 22 can play the role of fixing the wiring.

[0033] The fixed cable tray 2 is provided with a cable pressing mechanism 3 on both sides. The cable pressing mechanism 3 includes a pressing frame 31, which is rotatably connected to the cable tray frame 21. The cable tray frame 21 is fixedly connected to both sides of the pressing rod 32. The pressing frame 31 and the pressing rod 32 are slidably connected. The surface of the pressing rod 32 is provided with a spring for squeezing and pushing the pressing frame 31. The cable pressing mechanism 3 squeezes the cable into the inner side of the organizing groove 4 by pressing the pressing frame 31. The organizing groove 4 restricts the cable so that it can be collected for easy wiring and organization.

[0034] A tidying groove 4 is fixedly connected to the surface of the mounting plate 1. A wire pressing mechanism 3 is located inside the tidying groove 4. A wire dividing mechanism 5 is bolted to the surface of the mounting plate 1. The wire dividing mechanism 5 includes a wire dividing frame 51, which is bolted to the mounting plate 1. The wire dividing frame 51 is generally square in shape. A pad 56 is provided on the bottom surface of the inner side of the wire dividing frame 51. Grooves are arranged in an array on the surface of the pad 56. A guide groove 52 is opened at the upper end of the wire dividing frame 51. A positioning block 53 is slidably connected inside the guide groove 52. Above the wire dividing frame 51... The end face is provided with a tightening through hole groove 54, and the end face of the positioning block 53 is threaded with a positioning bolt 55. The positioning bolt 55 passes through the inside of the tightening through hole groove 54. The wire splitting mechanism 5 can use the sliding positioning block 53 to make the separated wires be snapped onto the surface of the pad 56. By setting the positioning bolt 55 to pass through the tightening through hole groove 54, the positioning block 53 can be fixed in a proper position. The wire splitting mechanism 5 fixes and controls the scattered wires, making the door installation more convenient and quick and preventing the wires from blocking the installation parts.

[0035] A wrapping cage 6 is rotatably connected to the surface of the installation arrangement plate 1. A bundled pipe 7 is provided inside the wrapping cage 6. The wrapping cage 6 includes a first rotating shaft 61, which is rotatably connected to the installation arrangement plate 1. The wrapping cage 6 also includes a second rotating shaft 62. The bundled pipe 7 is S-shaped and winds around the outside of the first rotating shaft 61 and the second rotating shaft 62. Both the upper and lower ends of the first rotating shaft 61 and the second rotating shaft 62 are provided with conduit cover plates 63. Both ends of the upper and lower sets of conduit cover plates 63 are provided with cover bends 64. The cover bends 64 wrap around the outside of the bundled pipe 7 and are used to wrap the wrapping cage. When rotating, the bundled pipe 7 is pushed to prevent it from slipping off the outside of the second rotating shaft 62. The lower end of the conduit cover plate 63 near the second rotating shaft 62 is fixedly connected to a rocker plate 65. The rocker plate 65 is slidably connected to the installation arrangement plate 1. The wrapping cage 6 can wrap the bundled pipe 7 inside through the conduit cover plate 63 and the cover bending rod 64, so that the bending of the bundled pipe 7 can be controlled by the wrapping cage 6. By rotating the wrapping cage 6 around the first rotating shaft 61, the bundled pipe 7 around the first rotating shaft 61 can change its position when the wrapping cage 6 rotates, thereby changing the distance away from the fixed cable tray 2.

[0036] A connecting line 8 is provided inside the bundled pipe 7, and a groove is provided above the sorting groove 4. The pressing mechanism 3 can press the connecting line 8 into the groove above the sorting groove 4, and the sorting groove 4 can collect the three connecting lines 8 inside.

[0037] The connecting line 8 passes through the fixed cable tray 2 and runs under the wire pressing mechanism 3. A cable routing bracket 9 is fixedly connected to the surface of the mounting plate 1. One end of the bundled pipe 7 is fixedly connected to the mounting plate 1, and the other end is slidably connected to the cable routing bracket 9. A traction mechanism 10 is rotatably connected to the free end of the package cage 6 to pull the package cage 6 to rotate. The cable routing bracket 9 includes a positioning support plate 91. A guide rod 92 is fixedly connected to the surface of the positioning support plate 91. A door connecting plate 93 is fixedly connected to the end of the guide rod 92 away from the positioning support plate 91. The door connecting plate 93 is fixedly connected to... A limiting strip 94 is connected to the outside of the traction mechanism 10 to limit the position. The cable routing bracket 9 is provided with a door connecting plate 93, which allows the device to be directly connected to the inner wall of the door, so that the device can be fixed on the side of the door, making the bundled pipe 7 more aesthetically pleasing as it passes through the door. By providing a guide rod 92, the bundled pipe 7 can slide along a predetermined setting, preventing the problem of the bundled pipe 7 being squeezed and damaged when the door is rotated after long-term use. By providing a limiting strip 94, the traction mechanism 10 can be restricted in position, which is convenient for installation and management.

[0038] The bundled pipe 7 is a bendable circular tube. A conversion joint 71 is connected to the end face of the bundled pipe 7. The conversion joint 71 disperses the connecting lines 8, which form a circular cross-section inside the bundled pipe 7, into long strips. One end of the bundled pipe 7 near the conversion joint 71 is fixedly connected to the mounting plate 1. A traction ring 72 is fixedly connected to the outer side of the other end of the bundled pipe 7. The traction ring 72 slides on the surface of the guide rod 92. The bundled pipe 7 is used to wrap around the outside of the connecting lines 8, so that the scattered connecting lines 8 can be organized and concentrated to pass through the door, making the wiring layout neater and easier to manage. By setting the traction ring 72 on the surface of the bundled pipe 7, the bundled pipe 7 can slide along the guide rod 92 when it moves.

[0039] The movable corners of the bundled pipe 7 are made of a softer material, while the areas without movable requirements are made of a harder material. This is to accommodate the sliding of the conversion joint 71 on the surface of the guide rod 92 when the wrapping cage 6 rotates.

[0040] The traction mechanism 10 includes a rocker column 101, which is rotatably connected to the surface of the rocker plate 65. A traction line 102 is fixedly connected to the surface of the rocker column 101. The traction line 102 passes through the limiting strip 94. A return spring 103 is sleeved on the outside of the traction line 102. A limiting plate 104 is provided on the end face of the return spring 103. The limiting plate 104 is fixedly connected to the surface of the mounting plate 1. The return spring 103 is located between the limiting plate 104 and the rocker column 101. The traction line 102 passes through the limiting plate 104. By setting the traction line 102, the traction mechanism 10 can pull the wrapping cage 6 first when the car door is opened, so that the bundled pipe 7 is pushed out. When the car door moves, the bundled pipe 7 can follow and extend, preventing the problem of damage to the wiring connection position caused by pulling the connecting line 8 when the car door is opened.

[0041] In use, first, fix the mounting plate 1 inside the car door. Rotate the adjusting screw 23 to slide the wire trough pressure plate 22 inside the wire trough frame 21, pressing down to fix the connecting wire 8. A spring pushes the pressing frame 31 to slide along the pressing rod 32, pressing and confining the connecting wire 8 within the organizing groove 4. By moving the connecting wires 8 to different positions, slide the positioning block 53 inside the guide groove 52 of the wire splitting frame 51, engaging the separated wire harness surfaces. Tighten the positioning bolt 55 inside the through-hole groove 54 by rotating it, fixing the positioning block 53 to the surface of the pad 56. This ensures that each separated wire harness is fixed to the pad 56, thus securing the separated wire harnesses. The location makes door installation more convenient. After the connection line 8 is connected and installed, the door connecting plate 93 is connected to the outer wall of the door where the door and door frame are connected. The traction line 102 is passed through the door and fixedly connected to the door frame. When the door is opened, the traction line 102 is pulled first. The traction line 102 pulls the rocker arm column 101 to squeeze the reset spring 103. Through the pulling of the traction line 102, the wrapping cage 6 is pulled to rotate around the first rotating shaft 61. The rotation of the wrapping cage 6 drives the inner bundled pipe 7. The bundled pipe 7 relaxes under the rotation of the wrapping cage 6 to assist in pushing the traction ring 72 to rotate on the surface of the guide rod 92. This allows the bundled pipe 7 to assist in pushing when the door rotates, avoiding the problem of the door rotating pulling the line and causing damage to the line connection.
