[0001] The present invention relates to the technical field of fixing devices, and particularly relates to a fixing device for an automotive wiring harness on a vehicle frame. Background Art

[0002] The automotive wiring harness is the network main body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. A wiring harness refers to a component formed by crimping contact terminals made of copper material onto electric wires and cables, and then externally molding an insulator or adding a metal shell, etc., and bundling the wiring harness to form a component for connecting circuits. The wiring harness industrial chain includes electric wires and cables, connectors, processing equipment, wiring harness manufacturing, and downstream application industries. The wiring harness is widely used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and generally has an H-shaped configuration. The fixing device for an automotive wiring harness on a vehicle frame is a device used to fix the automotive wiring harness on the vehicle frame, aiming to ensure that the wiring harness remains stable during vehicle operation and avoid loosening or damage due to vibration or collision.

[0003] In the prior art, the automotive wiring harness fixing device is prone to loosening due to vibration or the failure of the buckle structure under bumpy road conditions, resulting in wiring harness displacement, frictional abnormal noise, and even interference with surrounding components, leading to risks such as insulation layer breakage and short circuit, directly affecting the functional safety and durability of the vehicle. Summary of the Invention

[0004] The present invention discloses a fixing device for an automotive wiring harness on a vehicle frame, aiming to solve the technical problem that the existing automotive wiring harness fixing device in the background art is prone to loosening due to vibration or the failure of the buckle structure under bumpy road conditions, affecting the functional safety and durability of the vehicle.

[0005] A fixing device for an automotive wiring harness on a vehicle frame proposed by the present invention includes a fixed base. A fixed collar is fixedly connected to the top of the fixed base. A locking and fixing module is arranged on the fixed collar, and a movable ring member is slidably connected to the inner wall of the fixed collar. The same reverse locking module is arranged on the fixed base and the movable ring member. The reverse locking module includes an installation rod frame, the installation rod frame is connected to the top of the fixed base by bolts, and a slide rail member is connected to one side of the installation rod frame by bolts. A sliding block is slidably connected to the inner wall of the slide rail member. The locking and fixing module includes a fixed ring member, the fixed ring member is fixedly connected to the outside of the fixed collar, and a guide rail member is fixedly connected to the outer wall of one side of the fixed ring member.

[0006] In a preferred solution, an arc-shaped rack is fixedly connected to the inner wall of one side of the movable ring member, and a limiting ring member is fixedly connected to the top of the installation rod frame. The movable ring member slides inside the limiting ring member. Round holes are formed in both the installation rod frame and the limiting ring member, and the same rotating shaft is rotatably connected in the two round holes through bearings. A locking gear is fixedly connected to the outer part of one end of the rotating shaft, and the locking gear meshes with the arc-shaped rack.

[0007] In a preferred embodiment, a rotating disk is fixedly connected to one end of the rotating shaft away from the locking gear. A fixed rod is fixedly connected to one side of the rotating disk. A rotating frame is fixedly connected to the top of the sliding block. A fixing hole is formed in the rotating frame. A thin rod is fixedly connected in the fixing hole. A connecting rod is movably connected to the outside of the thin rod. One end of the connecting rod away from the rotating frame is movably connected to the fixed rod.

[0008] In a preferred embodiment, a sliding member is slidably connected to the inner wall of the sliding block. A limiting rod is fixedly connected to one side of the sliding member. A limiting spring is fixedly connected to one side of the sliding member. One end of the limiting spring away from the sliding member is fixedly connected to the inner wall of the sliding block.

[0009] In a preferred embodiment, a counterweight is fixedly connected to the bottom of the sliding block. A ratchet groove is formed in the slide rail member. The limiting rod slides in the ratchet groove.

[0010] By providing a reverse locking module, when the vehicle jolts during driving, the counterweight will drive the sliding block to slide in the slide rail member under the action of gravity. The rotating disk is rotated by pulling the connecting rod, driving the locking gear to rotate. By the meshing of the arc-shaped rack and the locking gear, the movable ring member is tightened. At the same time, when the sliding block slides downward, the limiting rod drives the sliding member to compress the limiting spring and slide smoothly under the action of the ratchet groove. Reverse sliding is prevented due to the blocking of the ratchet groove. Progressive tightening can be achieved by using the vibration generated by the jolt, effectively suppressing the displacement and loosening tendency of the wire harness, significantly reducing the risk of frictional noise and insulation wear, and overall improving the safety protection performance and system durability performance during vehicle driving.

[0011] In a preferred embodiment, a winding wheel is movably connected to the inner wall of one side of the fixed collar. A winding rope is wound around the outside of the winding wheel. One end of the winding rope away from the winding wheel is fixedly connected to the movable ring member. A fixed frame is fixedly connected to the inner wall of the fixed collar. A guiding wheel is movably connected to the fixed frame. The winding rope slides on the outside of the guiding wheel. An installation rod is fixedly connected to the inner wall of the fixed collar.

[0012] In a preferred embodiment, a rotating rod is fixedly connected to one side of the winding wheel away from the inner wall of the fixed collar. A locking gear is fixedly connected to the outer wall of one end of the rotating rod away from the winding wheel. Rotating holes are formed in both the installation collar and the guide rail member. The rotating rod is movably connected in the two rotating holes.

[0013] In a preferred solution, the guide rail member is internally slidably connected with a sliding frame 1 and a sliding frame 2, and two spring rods are fixedly connected to the inner walls on both sides of the opposite sides of the guide rail member, and one end of the multiple spring rods away from the inner wall of the guide rail member is respectively fixedly connected to the sliding frame 1 and the sliding frame 2, and the opposite sides of the sliding frame 1 and the sliding frame 2 are fixedly connected with a locking gear ring.

[0014] In a preferred embodiment, two elastic sheets are fixedly connected to one side of the guide rail member, and locking rods are fixedly connected to the opposite sides of the two elastic sheets. Locking sliding holes are provided on sliding frame one and sliding frame two, and the two locking rods slide in the corresponding locking sliding holes.

[0015] In a preferred embodiment, the movable ring is provided with a mounting hole, a sliding rod is fixedly connected in the mounting hole, and a sliding slot is provided on the fixed ring, the sliding rod slides in the sliding slot, and a toggle piece is fixedly connected to one side outer wall of the movable ring.

[0016] By providing a locking and fixing module, the elastic sheets on both sides are pushed toward the center to make the locking rods on both sides disengage from the locking sliding holes, and the sliding frame 1 and the sliding frame 2 respectively slide to both sides under the elastic action of the corresponding spring rods, driving the locking tooth ring to disengage from the locking gear, so that the rotating rod and the winding wheel can rotate freely, and the winding spring elastically recovers while tightening, driving the winding wheel to rotate and gather the winding rope to the outside. After the automobile wiring harness is fixed, the sliding frame 1 and the sliding frame 2 are pushed to reset, and locked again by the elastic sheet and the locking rod, so that the wiring harness can be locked and reinforced for the second time, reducing the risk of accidental loosening under external force impact, further enhancing the long-term reliability of the device, and increasing the convenience during disassembly and assembly.

[0017] From the above, it can be seen that the fixing device of the automobile wiring harness frame provided by the present invention uses the reverse locking module to achieve progressive tightening by utilizing the vibration generated by the bumps when the automobile is bumpy during driving, thereby effectively suppressing the displacement and loosening trend of the wiring harness, significantly reducing the risk of friction noise and insulation wear, and improving the overall safety protection performance and system durability during vehicle driving. In addition, when fixing the wiring harness, the locking and fixing module can be used for secondary locking and reinforcement, reducing the risk of accidental loosening under external force impact, and further enhancing the long-term reliability of the device.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0027] A fixing device for an automotive wiring harness disclosed by the present invention is mainly applied to scenarios where existing automotive wiring harness fixing devices are prone to loosen due to vibration or failure of the buckle structure under bumpy road conditions, affecting the functional safety and durability of the vehicle.

[0028] Refer to Figures 1 - 7, A fixing device for an automotive wire harness frame, comprising a fixing base 1. A fixing collar 2 is fixedly connected to the top of the fixing base 1. A locking and fixing module 7 is arranged on the fixing collar 2. An active ring member 3 is slidably connected to the inner wall of the fixing collar 2. The same reverse locking module 6 is arranged on the fixing base 1 and the active ring member 3. The reverse locking module 6 includes a mounting rod frame 601. The mounting rod frame 601 is bolted to the top of the fixing base 1. A slide rail member 606 is bolted to one side of the mounting rod frame 601. A sliding block 610 is slidably connected to the inner wall of the slide rail member 606. The locking and fixing module 7 includes a fixed ring member. The fixed ring member is fixedly connected to the outside of the fixing collar 2. A guide rail member 710 is fixedly connected to the outer wall of one side of the fixed ring member.

[0029] Refer to Figure 1 , Figure 2 and Figure 3 , An arc-shaped rack 602 is fixedly connected to the inner wall of one side of the active ring member 3. A limiting ring member 607 is fixedly connected to the top of the mounting rod frame 601. The active ring member 3 slides inside the limiting ring member 607. Round holes are formed in both the mounting rod frame 601 and the limiting ring member 607. The same rotating shaft 603 is rotatably connected through bearings in the two round holes. A locking gear 604 is fixedly connected to the outside of one end of the rotating shaft 603. The locking gear 604 meshes with the arc-shaped rack 602.

[0030] Refer to Figure 1 , Figure 3 and Figure 4 , A rotating disc 605 is fixedly connected to the end of the rotating shaft 603 away from the locking gear 604. A fixed rod member 608 is fixedly connected to one side of the rotating disc 605. A rotating frame 612 is fixedly connected to the top of the sliding block 610. A fixing hole is formed in the rotating frame 612. A thin rod is fixedly connected in the fixing hole. A connecting rod 613 is movably connected to the outside of the thin rod. One end of the connecting rod 613 away from the rotating frame 612 is movably connected to the fixed rod member 608.

[0031] Refer to Figure 1 , Figure 4 and Figure 5 , A sliding member 614 is slidably connected to the inner wall of the sliding block 610. A limiting rod member 615 is fixedly connected to one side of the sliding member 614. A limiting spring 616 is fixedly connected to one side of the sliding member 614. One end of the limiting spring 616 away from the sliding member 614 is fixedly connected to the inner wall of the sliding block 610.

[0032] Refer to Figure 1 , Figure 4 and Figure 5 , A counterweight block 611 is fixedly connected to the bottom of the sliding block 610. A ratchet groove 609 is formed in the slide rail member 606. The limiting rod member 615 slides in the ratchet groove 609.

[0033] In a specific application scenario, when the vehicle jolts during driving, the counterweight 611 will drive the sliding block 610 to slide within the slide rail member 606 under the action of gravity. The rotating disk 605 is rotated by pulling through the connecting rod 613, driving the locking gear 604 to rotate. By using the meshing of the arc-shaped rack 602 and the locking gear 604, the movable ring member 3 is driven to tighten. At the same time, when the sliding block 610 slides downward, the limiting rod member 615 drives the sliding member 614 to compress the limiting spring 616 to slide smoothly under the action of the ratchet groove 609. When sliding in the reverse direction, it cannot proceed due to the blockage of the ratchet groove 609. It can achieve progressive tightening by using the vibration generated by the jolts, effectively suppressing the displacement and loosening trend of the wire harness, significantly reducing the risks of frictional abnormal noise and insulation wear, and overall improving the safety protection performance and system durability performance during vehicle driving.

[0034] Refer to Figure 1 、 Figure 2 and Figure 6 As shown in FIGS.

[0035] Refer to Figure 1 、 Figure 6 and Figure 7 One inner wall side of the fixed collar 2 is movably connected with a winding wheel 704. A winding rope 703 is wound around the outside of the winding wheel 704. One end of the winding rope 703 away from the winding wheel 704 is fixedly connected to the movable ring member 3. And an inner wall of the fixed collar 2 is fixedly connected with a fixed bracket 701. A guiding wheel 702 is movably connected to the fixed bracket 701. The winding rope 703 slides outside the guiding wheel 702. An inner wall of the fixed collar 2 is fixedly connected with a mounting rod member 705. A mounting groove is formed in the mounting rod member 705. A torsion spring 706 is fixedly connected in the mounting groove. One end of the torsion spring 706 away from the mounting rod member 705 is fixedly connected to the inner wall of the winding wheel 704.

[0036] Refer to Figure 1 、 Figure 6 and Figure 7 As shown in FIGS.

[0037] Refer to Figure 1 、 Figure 6 andFigure 7 Two elastic sheets 715 are fixedly connected to one side of the guide rail member 710, and locking rods 716 are fixedly connected to the opposite sides of the two elastic sheets 715. Locking sliding holes are opened on the sliding frame 1 712 and the sliding frame 2 713, and the two locking rods 716 slide in the corresponding locking sliding holes.

[0038] Reference Figure 1 and Figure 2 A mounting hole is provided on the movable ring 3, a sliding rod 5 is fixedly connected in the mounting hole, and a sliding slot 4 is provided on the fixed ring 2, the sliding rod 5 slides in the sliding slot 4, and a toggle member 8 is fixedly connected to the outer wall of one side of the movable ring 3.

[0039] In a specific application scenario, the elastic sheets 715 on both sides are pushed toward the center to disengage the locking rods 716 on both sides from the locking slide holes, and the sliding frame 1 712 and the sliding frame 2 713 slide to both sides under the elastic action of the corresponding spring rods 711, respectively, driving the locking tooth ring 714 to disengage the locking gear 709, so that the rotating rod 708 and the winding wheel 704 can rotate freely, and the winding spring 706 elastically recovers while tightening, driving the winding wheel 704 to rotate and gather the winding rope 703 to the outside. After the automobile wiring harness is fixed, the sliding frame 1 712 and the sliding frame 2 713 are pushed to reset, and locked again by the elastic sheet 715 and the locking rod 716, so that the wiring harness can be locked and reinforced for the second time, reducing the risk of accidental loosening under external force impact, further enhancing the long-term reliability of the device, and increasing the convenience during disassembly and assembly.

[0040] It should be noted that the restoring elastic force of the fixed collar 2 and the movable ring 3 is greater than the elastic force of the coil spring 706, so that when the fixed collar 2 and the movable ring 3 are relaxed and restored, the winding wheel 704 will be driven to rotate through the winding rope 703, so that the coil spring 706 stores energy.

[0041] Working principle: Pass the automobile wiring harness through and place it between the fixed ring 2 and the movable ring 3, and push the elastic sheets 715 on both sides toward the center to disengage the locking rods 716 on both sides from the locking sliding holes. The sliding frame 1 712 and the sliding frame 2 713 slide to both sides under the elastic action of the corresponding spring rods 711, respectively, driving the locking gear ring 714 to disengage from the locking gear 709, so that the rotating rod 708 and the winding wheel 704 can rotate freely. At this time, push the toggle member 8 to drive the movable ring 3 to slide, tighten the automobile wiring harness, and at the same time, the winding spring 706 elastically recovers, driving the winding wheel 704 to rotate and gather the winding rope 703 to the outside. After the automobile wiring harness is fixed, push the sliding frame 1 712 and the sliding frame 2 713 in the opposite direction to reset them, and then re-engage the wiring harness. The reverse locking module 6 is installed to the specified position by locking through the elastic sheet 715 and the locking rod 716. When the car is bumpy during driving, the counterweight block 611 will drive the sliding block 610 to slide in the sliding rail 606 under the action of gravity, and pull the rotating disk 605 to rotate through the connecting rod 613, driving the locking gear 604 to rotate, and utilizing the meshing of the arc-shaped rack 602 and the locking gear 604 to drive the movable ring 3 to tighten. At the same time, when the sliding block 610 slides downward, the limiting rod 615 drives the sliding member 614 to compress the limiting spring 616 under the action of the ratchet groove 609, and slides smoothly. Reverse sliding cannot be carried out due to the obstruction of the ratchet groove 609, and progressive locking is performed to prevent the device from loosening due to bumps.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
