Description

Technical Field

[0001] This utility model relates to a wire harness installation device, and more particularly to a wire harness constraint structure. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. Without wiring harnesses, there would be no automotive circuits. A wiring harness is an assembly that connects circuits by crimping copper contact terminals (connectors) with wires and cables, and then molding an insulator or adding a metal shell on the outside.

[0003] The existing installation structure lacks adjustment and fixation, and the fixing sleeve cannot apply appropriate pressure to the wiring harness, resulting in continuous shaking and friction during operation of the wiring harness, accelerated wear of the insulation layer, a surge in the risk of short circuit and leakage, and the wiring harness is very easy to loosen and fall off when the vehicle vibrates, affecting the wiring harness connection and causing frequent equipment malfunctions.

[0004] Therefore, this case aims to provide a wire harness constraint structure that allows the fixing sleeve to apply appropriate pressure to the wire harness, avoiding the risks of running vibration and friction, insulation layer wear and short circuit leakage, preventing loosening and falling off when the vehicle vibrates, and ensuring the technical effect of wire harness connection and equipment operation. Utility Model Content

[0005] This invention provides a wire harness constraint structure that can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A wire harness constraint structure includes a fixing sleeve, with multiple wire harness materials fixedly connected to the inner side of the fixing sleeve, and symmetrical adjustment fixing components provided on the outer side of the fixing sleeve. A telescopic adjustment component is provided at the bottom end of the adjustment fixing component, and a symmetrical bottom frame is provided at the bottom end of the telescopic adjustment component. A main magnetic plate is fixedly connected to the bottom end of the bottom frame, and fixing frames are provided at both ends of the bottom frame. A secondary magnetic plate is fixedly connected to the bottom end of each fixing frame.

[0008] The adjusting and fixing assembly includes a fixing ring, a fixing rod is fixedly connected to the inner side of the fixing ring, and an adjusting ring is movably connected to the outer side of the fixing rod.

[0009] The telescopic adjustment assembly includes symmetrical annular components, with the inner side of the annular components and the outer side of the adjustment link being movably connected, and the bottom end of each annular component being fixedly connected to a base.

[0010] In a preferred embodiment, the adjusting and fixing assembly further includes a motor frame, the bottom end of which is fixedly connected to the front end of the fixing ring. A servo motor is fixedly connected to the inner side of the motor frame, and the power output shaft of the servo motor is connected to a movable component via a coupling. The bottom end of the movable component is movably connected to the front end of the fixing ring. An adjusting rope is fixedly connected to the inner side of the movable component, and a limit ring is movably connected to the outer side of the adjusting rope. The bottom end of the limit ring is fixedly connected to the front end of the fixing ring. A positioning component is fixedly connected to the front end of the adjusting rope, and a sliding component is fixedly connected to the bottom end of the positioning component. The bottom end of the sliding component is connected to the adjusting ring. The front ends of the components are fixedly connected. A sliding groove is provided on the upper side of the front end of the fixed ring component, and the sliding component is movably connected inside the sliding groove. A round rod is fixedly connected to the inner side of the front end of the fixed ring component, and a gear cylinder is movably connected to the outer side of the round rod. An annular gear plate is movably connected to the outer side of the gear cylinder. The annular gear plate and the gear cylinder mesh with each other through tooth grooves. The inner side of the annular gear plate is fixedly connected to the outer side of the adjusting ring component. A compression spring is fixedly connected to the opposite side of the fixed ring component and the adjusting ring component. An auxiliary retaining plate is fixedly connected to the front end of each compression spring. The inner side of the auxiliary retaining plate is in contact with the outer side of the fixed sleeve.

[0011] When the automotive wiring harness is adjusted using an adjustable fixing component, a servo motor drives a movable part to rotate. Because an adjusting rope is fixedly connected to the inner side of the movable part, and a limit ring (which guides the rope's movement) is movably connected to the outer side of the adjusting rope, the rotation of the movable part causes the adjusting rope to move. A positioning component is fixedly connected to the front end of the adjusting rope, and a sliding component is fixedly connected to the bottom end of the positioning component. The sliding component is movably connected within a groove hole on the upper side of the front end of the fixed ring. As the adjusting rope moves, it pulls the positioning component and the sliding component to move within the groove hole. Since the bottom end of the sliding component is fixedly connected to the front end of the adjusting ring, the adjusting ring moves along the inner side of the fixed ring as the sliding component moves. When the adjusting ring moves, it drives the ring gear plate to move, which in turn causes the gear cylinder to rotate on the round rod through the meshing relationship of the tooth grooves. This gear transmission structure allows the adjusting ring to... The movement is smoother and more precise, and the adjustment force and stability are increased to a certain extent. During the movement of the adjusting ring, the compression springs on the opposite side of the fixed ring and the adjusting ring are further compressed. After being compressed, the compression springs generate elastic force, which is applied to the outside of the fixed sleeve through the auxiliary retaining plate, thereby achieving clamping and fixing of the outside of the fixed sleeve. The presence of the compression spring can make a certain degree of adaptive adjustment according to the size and shape of the fixed sleeve, ensuring the tightness and stability of the fixation. During the process, by adjusting the fixation, the fixed sleeve can provide appropriate pressure to the wire harness, ensuring that the wire harness will not rub against other parts due to shaking when the equipment is running, preventing the insulation layer from wearing down, reducing the risk of short circuit and leakage. In the vibration environment of the vehicle, the adjustment fixation can make the fixed sleeve tightly bind the wire harness, preventing it from loosening or falling off due to vibration, ensuring the wire harness connection is stable and the equipment is operating normally.

[0012] In a preferred embodiment, symmetrical telescopic rods are fixedly connected to the top of the base frame, and symmetrical buffer springs are fixedly connected to the top of the base frame. The buffer springs are all located on the outside of the telescopic rods, and the tops of the buffer springs and telescopic rods are fixedly connected to the bottom of the base. Fixing members are provided between the symmetrical telescopic rods, and the tops of the fixing members are fixedly connected to the bottom of the base. A bidirectional telescopic drive rod is fixedly connected to the inside of the fixing member, and the two ends of the bidirectional telescopic drive rod are fixedly connected to the opposite side of the symmetrical fixed frame. A symmetrical bidirectional telescopic rod is fixedly connected to the inside of the base frame, and the two ends of the bidirectional telescopic rod are fixedly connected to the opposite side of the symmetrical fixed frame.

[0013] The system comprises a fixing component, a bidirectional telescopic drive rod, a telescopic bidirectional rod, a telescopic rod, and a buffer spring. After the wiring harness is fixed, when the magnetic plate is attracted to the interior of the car, the main magnetic plate at the bottom of the base frame and the auxiliary magnetic plate at the bottom of the fixing frame are in an initial attraction state. When it is necessary to increase the magnetic attraction area, the bidirectional telescopic drive rod is activated and extends. As the bidirectional telescopic drive rod extends, it pushes the two fixing frames to move away from each other. At the same time, the telescopic bidirectional rod also extends with the movement of the fixing frames, ensuring the stability and synchronicity of the movement of the fixing frames. As the fixing frames move outward, the auxiliary magnetic plate also moves accordingly, increasing the distance between the main magnetic plate and the auxiliary magnetic plate. The increased distance increases the overall magnetic coverage area, allowing it to better adhere to a larger area inside the car and enhance the stability of the fixed installation structure. During the movement of the fixed frame, the telescopic rod and buffer spring at the top of the bottom frame play a role. The telescopic rod can guide the movement direction of the fixing parts and the base, ensuring the linearity and stability of the movement. The buffer spring can absorb the impact force generated when the fixed frame moves, preventing structural damage or magnetic instability caused by sudden external forces. Furthermore, after the magnetic area is adjusted, the buffer spring can also provide a certain buffering effect, reducing the impact of vibration on the fixed installation structure during car driving.

[0014] In a preferred embodiment, the telescopic adjustment assembly further includes a drive motor. The power output shaft of the drive motor is connected to a rotating rod via a coupling. The bottom end of the rotating rod is movably connected to the top end of one of the bases. A rotating gear is fixedly connected to the outer side of the rotating rod, and a gear ring is movably connected to the outer side of the rotating gear. The rotating gear and the gear ring mesh with each other through tooth grooves. A rotating shaft is fixedly connected to the inner side of the gear ring, and a pull rope is fixedly connected to the inner side of the rotating shaft. A through hole is opened on the inner side of one of the bases, and the pull rope is movably connected inside the through hole. The front end of the pull rope is fixedly connected to the rear end of the other base. A spring rod is fixedly connected to opposite sides of the symmetrical bases. An auxiliary seat is movably connected to the outer side of both the spring rod and the pull rope. The outer side of the auxiliary seat is in contact with the outer side of the fixed sleeve, and telescopic springs are fixedly connected to both sides of the auxiliary seat. The telescopic springs are all located outside the pull rope, and the ends of the telescopic springs away from the auxiliary seat are fixedly connected to one side of the base.

[0015] The device features a telescopic adjustment component for fixing the wire harness according to its length or bends. When the wire harness is long and requires a wider fixing range, the drive motor starts, causing the rotating rod to rotate. As the rotating rod rotates, the outer rotating gear also rotates. Because the rotating gear and gear ring mesh through tooth grooves, the gear ring rotates along with the rotating gear. The rotation of the gear ring drives the inner rotating shaft to rotate, which in turn winds a pull rope. The pull rope passes through a hole in one of the bases and is pulled, causing the other base to move closer to the base where the drive motor is located. This increases the distance between the symmetrical bases. During this process, the spring rod is stretched, and the auxiliary seat slides on the pull rope and spring rod as the bases move. The telescopic spring is also stretched, and the auxiliary seat remains in contact with the outer side of the fixing sleeve, allowing for a wider fixing range for the wire harness. The system is designed to accommodate longer cable harnesses. When the cable harness bends, it exerts pressure on the fixing sleeve, which is then transmitted to the auxiliary seat. Under pressure, the auxiliary seat slides on the pull rope and spring rod, compressing the telescopic spring on one side and stretching the telescopic spring on the other side. The spring rod also deforms to adapt to the bending shape of the cable harness. The elastic deformation of the telescopic spring and spring rod buffers the stress generated by the bending of the cable harness, ensuring the fixing effect without excessively restricting it. This allows the cable harness to maintain a certain degree of bending freedom, completing the fixing adjustment of the cable harness according to its length or bending. During the process, the fixing position can be adjusted according to the actual length of the cable harness. Whether it is long-distance wiring or short-distance connection, the cable harness can be properly fixed through adjustment, avoiding loose and messy cable harnesses for excessively long cable harnesses or stretched cable harnesses for excessively short cable harnesses.

[0016] As can be seen from the above, the fixed installation structure for automotive wiring harnesses provided by this utility model allows the fixing sleeve to apply appropriate pressure to the wiring harness, avoiding the risks of shaking and friction during operation, insulation wear, and short circuit leakage. It also prevents loosening and falling off when the vehicle vibrates, thus ensuring the technical effect of wiring harness connection and equipment operation. Attached Figure Description

A servo motor 1312 is fixedly connected to the inner side of the motor frame 1313, and the power output shaft of the servo motor 1312 is connected to a movable member 1311 via a coupling. The bottom end of the movable member 1311 is movably connected to the front end of the fixing ring 1301. An adjusting rope 1309 is fixedly connected to the inner side of the movable member 1311, and a limiting ring 1310 is movably connected to the outer side of the adjusting rope 1309. The bottom end of the limiting ring 1310 is fixedly connected to the front end of the fixing ring 1301.

The bottom end of the sliding member 1307 is connected to the adjusting rope 1309. The front ends of the joint ring 1303 are fixedly connected. The upper side of the front end of the fixed ring 1301 is provided with a sliding groove hole, and the sliding member 1307 is movably connected inside the sliding groove hole. A round rod 1305 is fixedly connected to the inner side of the front end of the fixed ring 1301. A gear cylinder 1306 is movably connected to the outer side of the round rod 1305. A ring gear plate 1304 is movably connected to the outer side of the gear cylinder 1306. The ring gear plate 1304 and the gear cylinder 1306 mesh with each other through a tooth groove.

[0033] Specifically, when fixing and adjusting the automotive wiring harness, the servo motor 1312 drives the movable part 1311 to rotate. Since the movable part 1311 is connected to the adjusting rope 1309, the rotation of the movable part 1311 causes the adjusting rope 1309 to move. The adjusting rope 1309 pulls the positioning part 1308 and the sliding part 1307 to move in the sliding hole of the fixed ring 1301, which drives the adjusting ring 1303 to move along the inner side of the fixed ring 1301. The movement of the adjusting ring 1303 drives the ring gear plate 1304, and through the meshing of the gear teeth, the gear cylinder 1306 rotates on the round rod 1305, making the adjustment more stable and precise, and enhancing the force and stability. The movement of the adjusting ring 1303 compresses the spring 1314. The spring force acts on the outside of the fixed sleeve 1 through the auxiliary fixing plate 1315 to achieve clamping and fixing. It can also adaptively adjust according to the size and shape of the fixed sleeve 1 to ensure tight and stable fixing.

[0034] Reference Figure 1 Figure 2 , Figure 3 and Figure 4In a preferred embodiment, symmetrical telescopic rods 11 are fixedly connected to the top of the bottom frame 8, and symmetrical buffer springs 12 are fixedly connected to the top of the bottom frame 8. The buffer springs 12 are all located outside the telescopic rods 11, and the tops of the buffer springs 12 and the telescopic rods 11 are fixedly connected to the bottom of the base 1002. Fixing members 3 are provided between the symmetrical telescopic rods 11, and the top of the fixing members 3 is fixedly connected to the bottom of the base 1002. A bidirectional telescopic drive rod 4 is fixedly connected to the inner side of the fixing members 3, and the two ends of the bidirectional telescopic drive rod 4 are fixedly connected to the opposite side of the symmetrical fixed frame 5. A symmetrical telescopic bidirectional rod 7 is fixedly connected to the inner side of the bottom frame 8, and the two ends of the telescopic bidirectional rod 7 are fixedly connected to the opposite side of the symmetrical fixed frame 5.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 In a preferred embodiment, the telescopic adjustment assembly 10 further includes a drive motor 1004. The power output shaft of the drive motor 1004 is connected to a rotating rod 1003 via a coupling. The bottom end of the rotating rod 1003 is movably connected to the top end of one of the bases 1002. A rotating gear 1005 is fixedly connected to the outer side of the rotating rod 1003, and a gear ring 1006 is movably connected to the outer side of the rotating gear 1005. The rotating gear 1005 and the gear ring 1006 are meshed through tooth grooves. A rotating shaft 1007 is fixedly connected to the inner side of the gear ring 1006, and a pulling rope 1008 is fixedly connected to the inner side of the rotating shaft 1007. An opening is provided on the inner side of one of the bases 1002. There is a perforation, and the pull rope 1008 is movably connected inside the perforation. The front end of the pull rope 1008 is fixedly connected to the rear end of another base 1002. A spring rod 1010 is fixedly connected to the opposite side of the symmetrical base 1002. An auxiliary seat 1011 is movably connected between the spring rod 1010 and the outer side of the pull rope 1008. The outer side of the auxiliary seat 1011 is in contact with the outer side of the fixed sleeve 1. A telescopic spring 1009 is fixedly connected to both sides of the auxiliary seat 1011. The telescopic springs 1009 are all located outside the pull rope 1008. The end of the telescopic spring 1009 away from the auxiliary seat 1011 is fixedly connected to one side of the base 1002.

[0036] Specifically, when adjusting the wire harness fixation, if the wire harness is long, the fixation range needs to be increased. The drive motor 1004 drives the rotating rod 1003 and the rotating gear 1005 to rotate, which in turn causes the gear ring 1006 and the rotating shaft 1007 to rotate, winding the pull rope 1008 and pulling the other base 1002 closer, increasing the distance between the bases 1002. The spring rod 1010 is stretched, and the auxiliary seat 1011 moves accordingly and stretches the telescopic spring 1009, always in contact with the fixing sleeve 1, achieving a wide range of fixation to accommodate long wire harnesses. When the wire harness bends, the pressure is transmitted to the auxiliary seat 1011, causing it to slide on the pull rope 1008 and the spring rod 1010, compressing and stretching the telescopic spring 1009. The spring rod 1010 deforms, buffering the stress, ensuring the fixation effect while giving the wire harness the freedom to bend, thus completing the fixation adjustment.

[0037] Working principle: When fixing and adjusting the automotive wiring harness, the servo motor 1312 drives the movable part 1311 to rotate. Since the movable part 1311 is connected to the adjusting rope 1309, the rotation of the movable part 1311 causes the adjusting rope 1309 to move. The adjusting rope 1309 pulls the positioning part 1308 and the sliding part 1307 to move in the sliding hole of the fixed ring 1301, which drives the adjusting ring 1303 to move along the inner side of the fixed ring 1301. The movement of the adjusting ring 1303 drives the ring gear plate 1304. Through the meshing of the teeth, the gear cylinder 1306 rotates on the round rod 1305, making the adjustment more stable and precise, and enhancing the force and stability. The movement of the adjusting ring 1303 compresses the spring 1314. The spring force acts on the outside of the fixed sleeve 1 through the auxiliary fixing plate 1315 to achieve clamping and fixing. It can also adaptively adjust according to the size and shape of the fixed sleeve 1 to ensure tight and stable fixing.

[0038] When adjusting the wire harness fixation, if the wire harness is long, the fixation range needs to be increased. The drive motor 1004 drives the rotating rod 1003 and the rotating gear 1005 to rotate, which in turn causes the gear ring 1006 and the rotating shaft 1007 to rotate, winding the pull rope 1008 and pulling the other base 1002 closer, increasing the distance between the bases 1002. The spring rod 1010 is stretched, and the auxiliary seat 1011 moves accordingly and stretches the telescopic spring 1009, always in contact with the fixing sleeve 1, achieving a wide range of fixation to accommodate long wire harnesses. When the wire harness bends, the pressure is transmitted to the auxiliary seat 1011, causing it to slide on the pull rope 1008 and the spring rod 1010, compressing and stretching the telescopic spring 1009. The spring rod 1010 deforms, buffering the stress, ensuring both the fixation effect and giving the wire harness the freedom to bend, thus completing the fixation adjustment.

[0039] After the wiring harness is fixed, the magnetic plate is adsorbed inside the car. The main magnetic plate 9 and the auxiliary magnetic plate 6 are initially adsorbed. When it is necessary to increase the magnetic attraction area, the bidirectional telescopic drive rod 4 extends and pushes the fixing frame 5 to move outward. The telescopic bidirectional rod 7 extends synchronously to ensure stability and synchronization. The auxiliary magnetic plate 6 moves outward with the fixing frame 5, increasing the distance between the main magnetic plate 9 and the auxiliary magnetic plate 6, expanding the magnetic attraction coverage area, and enhancing the fixing stability. During the movement of the fixing frame 5, the telescopic rod 11 guides the fixing part 3 and the base 1002 to move linearly, and the buffer spring 12 absorbs the impact force of the movement.
