Description

Technical Field

[0001] The present invention relates to the technical field of automotive wiring harnesses, and particularly to a fixed installation structure for an automotive wiring harness. Background Art

[0002] An automotive wiring harness is the network main body of an automotive circuit. Without a wiring harness, there would be no automotive circuit. A wiring harness refers to a component formed by crimping contact terminals (connectors) made of copper material onto electric wires and cables, and then molding an insulator outside or adding a metal shell, etc., and bundling the wiring harness to form a component for connecting circuits.

[0003] The existing installation structure lacks adjustment and fixation. It is difficult for the fixing sleeve to apply appropriate pressure to the wiring harness, resulting in continuous shaking and friction of the wiring harness during operation, increased wear of the insulating layer, soaring risk of short circuit and leakage, and the wiring harness is extremely likely to loosen and fall off when the vehicle vibrates, affecting the wiring harness connection and causing frequent errors in equipment operation. Summary of the Invention

[0004] The present invention discloses a fixed installation structure for an automotive wiring harness, aiming to solve the technical problems of the existing fixed installation structure being unable to adjust and fix, difficult to apply appropriate pressure to the wiring harness, shaking and wear of the wiring harness, increased leakage risk, easy to fall off when the vehicle vibrates, and affecting the wiring harness connection and equipment operation.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A fixed installation structure for an automotive wiring harness includes a fixing sleeve. A plurality of wiring harness materials are fixedly connected to the inner side of the fixing sleeve. Symmetrical adjustment and fixation components are arranged on the outer side of the fixing sleeve. A telescopic adjustment component is arranged at the bottom end of the adjustment and fixation component. Symmetrical bottom frames are arranged at the bottom end of the telescopic adjustment component. A main magnetic plate is fixedly connected to the bottom end of the bottom frame. Fixing frames are arranged at both ends of the bottom frame, and secondary magnetic plates are fixedly connected to the bottom ends of the fixing frames;

[0007] The adjustment and fixation component includes a fixed ring member. A fixed rod is fixedly connected to the inner side of the fixed ring member, and an adjustment ring member is movably connected to the outer side of the fixed rod;

[0008] The telescopic adjustment component includes symmetrical annular members. The inner sides of the annular members are movably connected to the outer sides of the adjustment links, and bases are fixedly connected to the bottom ends of the annular members.

[0009] In a preferred embodiment, the adjusting and fixing assembly further includes a motor mount. The bottom end of the motor mount is fixedly connected to the front end of the fixed ring member. A servo motor is fixedly connected to the inner side of the motor mount. The power output shaft of the servo motor is connected to a movable member through a coupling. The bottom end of the movable member is movably connected to the front end of the fixed ring member. An adjusting rope is fixedly connected to the inner side of the movable member. A limiting ring member is movably connected to the outer side of the adjusting rope. The bottom end of the limiting ring member is fixedly connected to the front end of the fixed ring member. The front end of the adjusting rope is fixedly connected to a positioning member. The bottom end of the positioning member is fixedly connected to a sliding member. The bottom end of the sliding member is fixedly connected to the front end of the adjusting ring member. A chute hole is formed in the upper side of the front end of the fixed ring member. The sliding member is movably connected inside the chute hole. A round rod is fixedly connected to the inner side of the front end of the fixed ring member. 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 are meshed with each other through a first tooth groove. The inner side of the annular gear plate is fixedly connected to the outer side of the adjusting ring member. Compression springs are fixedly connected between the opposite sides of the fixed ring member and the adjusting ring member. Auxiliary retaining plates are fixedly connected to the front ends of the compression springs. The inner sides of the auxiliary retaining plates are in contact with the outer side of the fixed sleeve.

[0010] By setting up an adjusting and fixing component, when fixing and adjusting the automotive wire harness, the servo motor drives the moving part to rotate. Since the adjusting rope is fixedly connected to the inner side of the moving part, and the outer side of the adjusting rope is movably connected with a limiting ring part (which plays a role in guiding the movement direction of the rope), the rotation of the moving part will cause the adjusting rope to start moving. The front end of the adjusting rope is fixedly connected with a positioning part, and the bottom end of the positioning part is fixedly connected with a sliding part. The sliding part is movably connected in the chute hole on the upper side of the front end of the fixed ring part. As the adjusting rope moves, it will pull the positioning part and the sliding part to move in the chute hole. Since the bottom end of the sliding part is fixedly connected to the front end of the adjusting ring part, the adjusting ring part will move along the inner side of the fixed ring part as the sliding part moves. When the adjusting ring part moves, it will drive the annular gear plate to move, and then through the meshing relationship of the first tooth groove, the gear cylinder will rotate on the round rod. This gear transmission structure can make the movement of the adjusting ring part more stable and precise, and to a certain extent increase the adjustment force and stability. During the movement of the adjusting ring part, the compression springs on the opposite sides of the fixed ring part and the adjusting ring part will be further compressed. After being compressed, the compression springs will generate elastic force, and this elastic force is applied to the outer side of the fixed sleeve through the auxiliary retaining plate, so as to realize the clamping and fixing of the outer side of the fixed sleeve. The existence of the compression springs can be adaptively adjusted to a certain extent according to the size and shape of the fixed sleeve to ensure the tightness and stability of the fixation. During the process, through adjustment and fixation, the fixed sleeve can provide an appropriate pressure on the wire harness to ensure that the wire harness will not rub against other components due to shaking during the operation of the equipment, prevent the wear of the insulating layer, and reduce the risks of short circuit and electric leakage. In the vibration environment of the vehicle, the adjustment and fixation can make the fixed sleeve tightly bind the wire harness to prevent it from loosening and falling off due to vibration, ensure the stable connection of the wire harness, and the normal operation of the equipment.

[0011] In a preferred solution, symmetric telescopic rods are fixedly connected to the top end of the bottom frame, and symmetric buffer springs are fixedly connected to the top end of the bottom frame. The buffer springs are all located outside the telescopic rods, and there are fixed connections between the top ends of the buffer springs and the telescopic rods and the bottom end of the base. A fixing part is arranged between the symmetric telescopic rods, and there is a fixed connection between the top end of the fixing part and the bottom end of the base. A bidirectional telescopic driving rod is fixedly connected to the inner side of the fixing part, and there are fixed connections between the two ends of the bidirectional telescopic driving rod and the opposite sides of the symmetric fixing frames. Symmetric telescopic bidirectional rods are fixedly connected to the inner side of the bottom frame, and there are fixed connections between the two ends of the telescopic bidirectional rods and the opposite sides of the symmetric fixing frames.

[0012] By being provided with a fixing member, a bidirectional telescopic driving rod, a telescopic bidirectional rod, a telescopic rod and a buffer spring, after the wire harness is fixed and the magnetic plate is adsorbed inside the vehicle, the main magnetic plate at the bottom end of the bottom frame and the secondary magnetic plate at the bottom end of the fixing frame are in the initial adsorption state. When it is necessary to increase the magnetic adsorption area, the bidirectional telescopic driving rod starts and extends. As the bidirectional telescopic driving rod extends, it will push the two fixing frames to move away from each other. At the same time, the telescopic bidirectional rod will also extend as the fixing frame moves, ensuring the stability and synchronization of the movement of the fixing frame. As the fixing frame moves outwards, the secondary magnetic plate also moves accordingly, increasing the distance between the main magnetic plate and the secondary magnetic plate, thereby increasing the overall magnetic adsorption coverage area, enabling better adsorption on a larger area inside the vehicle, and enhancing the stability of the fixed installation structure. During the movement of the fixing frame, the telescopic rod and the buffer spring at the top end of the bottom frame play a role. The telescopic rod can guide the movement direction of the fixing member and the base, ensuring the linearity and stability of the movement. The buffer spring can absorb the impact force generated when the fixing frame moves, preventing structural damage or unstable magnetic adsorption caused by sudden external forces. And after the magnetic adsorption area adjustment is completed, the buffer spring can also provide a certain buffering effect, reducing the impact of vibrations during vehicle driving on the fixed installation structure.

[0013] In a preferred solution, the telescopic adjustment assembly further includes a driving motor. The power output shaft of the driving motor is connected to a rotating rod through a coupling. The bottom end of the rotating rod is movably connected to the top end of one of the bases, and a rotating gear is fixedly connected to the outer side of the rotating rod. A gear ring is movably connected to the outer side of the rotating gear. The rotating gear and the gear ring are engaged with each other through tooth grooves. A rotating shaft is fixedly connected to the inner side of the gear ring, and a pulling rope is fixedly connected to the inner side of the rotating shaft. A through hole is formed in the inner side of one of the bases, and the pulling rope is movably connected inside the through hole. The front end of the pulling rope is fixedly connected to the rear end of the other base. A spring rod is fixedly connected between the opposite sides of the symmetric bases. An auxiliary seat is movably connected between the outer sides of the spring rod and the pulling rope. The outer side of the auxiliary seat is in contact with the outer side of the fixed sleeve. Both sides of the auxiliary seat are fixedly connected with telescopic springs. The telescopic springs are all located on the outer side of the pulling rope, and the ends of the telescopic springs away from the auxiliary seat are fixedly connected to one side of the base respectively.

[0014] By setting a telescopic adjustment component, when fixing and adjusting according to the length or bending of the wire harness, when the wire harness is long and the fixing range needs to be increased, the driving motor is started to drive the rotating rod to rotate. When the rotating rod rotates, the outer rotating gear rotates accordingly. Since the rotating gear meshes with the gear ring through the tooth grooves, the gear ring will rotate with the rotation of the rotating gear. When the gear ring rotates, it drives the inner rotating shaft to rotate. The rotating shaft winds and pulls the pulling rope, and the pulling rope passes through the perforation of one of the bases and is pulled. The pulling rope pulls the other base to move towards the base where the driving motor is located, increasing the distance between the symmetric bases. During this process, the spring rod is stretched, and the auxiliary seat slides on the pulling rope and the spring rod as the base moves. The telescopic spring is also stretched. The auxiliary seat always contacts the outside of the fixing sleeve to fix the wire harness in a wider range to adapt to the longer wire harness. When the wire harness is bent, the wire harness will exert a certain pressure on the fixing sleeve, which is then transmitted to the auxiliary seat. After the auxiliary seat is subjected to the pressure, it will slide on the pulling rope and the spring rod, compressing the telescopic spring on one side and stretching the telescopic spring on the other side. The spring rod will also undergo a certain deformation to adapt to the bending shape of the wire harness. The elastic deformations of the telescopic spring and the spring rod can buffer the stress generated by the bending of the wire harness, ensure the fixing effect of the wire harness, and at the same time will not cause excessive restraint on the wire harness, enabling the wire harness to maintain a certain degree of bending freedom, completing the fixing and adjustment of the wire harness according to its length or bending. During the process, the fixing position can be adjusted according to the actual length of the wire harness. Whether it is long-distance wiring or short-distance connection, the wire harness can be reasonably fixed through adjustment, avoiding the slack and mess of the too-long wire harness or the stretching of the too-short wire harness.

[0015] As can be seen from the above, a fixed installation structure of an automotive wire harness provided by the present invention has the technical effects of adjusting and fixing to make the fixing sleeve exert an appropriate pressure on the wire harness, avoiding risks such as running shaking and friction, insulation layer wear, and short-circuit leakage, preventing loosening and falling off during vehicle vibration, and ensuring the connection of the wire harness and the operation of the equipment.

[0028] The adjusting and fixing component 13 includes a fixing ring member 1301. A fixing rod 1302 is fixedly connected to the inner side of the fixing ring member 1301. And an adjusting ring member 1303 is movably connected to the outer side of the fixing rod 1302;

[0029] The telescopic adjusting component 10 includes symmetrical annular members 1001. The inner sides of the annular members 1001 are movably connected to the outer sides of the adjusting links. And bases 1002 are fixedly connected to the bottom ends of the annular members 1001.

[0030] Refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 6, in a preferred embodiment, the adjusting and fixing component 13 further includes a motor frame 1313. The bottom end of the motor frame 1313 is fixedly connected to the front end of the fixed ring member 1301. A servo motor 1312 is fixedly connected to the inner side of the motor frame 1313. The power output shaft of the servo motor 1312 is connected to a movable member 1311 through a coupling. The bottom end of the movable member 1311 is movably connected to the front end of the fixed ring member 1301. An adjusting rope 1309 is fixedly connected to the inner side of the movable member 1311. A limiting ring member 1310 is movably connected to the outer side of the adjusting rope 1309. The bottom end of the limiting ring member 1310 is fixedly connected to the front end of the fixed ring member 1301. The front end of the adjusting rope 1309 is fixedly connected to a positioning member 1308. The bottom end of the positioning member 1308 is fixedly connected to a sliding member 1307. The bottom end of the sliding member 1307 is fixedly connected to the front end of the adjusting ring member 1303. A chute hole is formed in the upper side of the front end of the fixed ring member 1301. The sliding member 1307 is movably connected inside the chute hole. A round rod 1305 is fixedly connected to the inner side of the front end of the fixed ring member 1301. A gear cylinder 1306 is movably connected to the outer side of the round rod 1305. An annular gear plate 1304 is movably connected to the outer side of the gear cylinder 1306. The annular gear plate 1304 and the gear cylinder 1306 are meshed with each other through a first tooth groove. The inner side of the annular gear plate 1304 is fixedly connected to the outer side of the adjusting ring member 1303.

The front ends of the compression springs 1314 are fixedly connected to auxiliary retaining plates 1315. The inner sides of the auxiliary retaining plates 1315 are in contact with the outer side of the fixed sleeve 1.

[0031] Specifically, when adjusting and fixing the automotive wire harness, the servo motor 1312 drives the movable member 1311 to rotate. Since the movable member 1311 is connected to the adjusting rope 1309, the rotation of the movable member 1311 causes the adjusting rope 1309 to move. The adjusting rope 1309 pulls the positioning member 1308 and the sliding member 1307 to move in the chute hole of the fixed ring member 1301, driving the adjusting ring member 1303 to move along the inner side of the fixed ring member 1301. The movement of the adjusting ring member 1303 drives the annular gear plate 1304. Through the tooth groove meshing, the gear cylinder 1306 rotates on the round rod 1305, making the adjustment smoother and more precise, enhancing the strength and stability. The movement of the adjusting ring member 1303 compresses the compression spring 1314. The spring force acts on the outer side of the fixed sleeve 1 through the auxiliary retaining plate 1315 to achieve clamping and fixing, and can also adaptively adjust according to the size and shape of the fixed sleeve 1 to ensure tight and stable fixation.

[0032] Refer to Figure 1 Figure 2 、 Figure 3 and Figure 4, in a preferred embodiment, symmetric telescopic rods 11 are fixedly connected to the top end of the bottom frame 8, and symmetric buffer springs 12 are fixedly connected to the top end of the bottom frame 8. The buffer springs 12 are all located outside the telescopic rods 11, and both the buffer springs 12 and the top ends of the telescopic rods 11 are fixedly connected to the bottom end of the base 1002. A fixing member 3 is arranged between the symmetric telescopic rods 11. The top end of the fixing member 3 is fixedly connected to the bottom end of the base 1002. A bidirectional telescopic driving rod 4 is fixedly connected to the inner side of the fixing member 3. Both ends of the bidirectional telescopic driving rod 4 are fixedly connected to the opposite sides of the symmetric fixing frames 5. And symmetric telescopic bidirectional rods 7 are fixedly connected to the inner side of the bottom frame 8. Both ends of the telescopic bidirectional rods 7 are fixedly connected to the opposite sides of the symmetric fixing frames 5.

[0033] Referring to 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 driving motor 1004. The power output shaft of the driving motor 1004 is connected to a rotating rod 1003 through a coupling. The bottom end of the rotating rod 1003 is movably connected to the top end of one of the bases 1002. And a rotating gear 1005 is fixedly connected to the outer side of the rotating rod 1003. 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. A pulling rope 1008 is fixedly connected to the inner side of the rotating shaft 1007. A through hole is formed in the inner side of one of the bases 1002. The pulling rope 1008 is movably connected between the insides of the through hole. And the front end of the pulling rope 1008 is fixedly connected to the rear end of the other base 1002. A spring rod 1010 is fixedly connected between the opposite sides of the symmetric bases 1002. An auxiliary seat 1011 is movably connected between the outer sides of the spring rod 1010 and the pulling rope 1008. The outer side of the auxiliary seat 1011 is in contact with the outer side of the fixed sleeve 1. And telescopic springs 1009 are fixedly connected to both sides of the auxiliary seat 1011. The telescopic springs 1009 are all located outside the pulling rope 1008. The ends of the telescopic springs 1009 away from the auxiliary seat 1011 are fixedly connected to one side of the base 1002.

[0034] Specifically, when adjusting the fixing of the wire harness, if the wire harness is relatively long, the fixing range needs to be increased. The driving motor 1004 drives the rotating rod 1003 and the rotating gear 1005 to rotate, thereby causing the gear ring 1006 and the rotating shaft 1007 to rotate, winding the pulling rope 1008, pulling another base 1002 closer, increasing the distance between the bases 1002, stretching the spring rod 1010, and the auxiliary seat 1011 follows and stretches the telescopic spring 1009, always contacting the fixing sleeve 1, achieving a wide-range fixing to adapt to the long wire harness. When the wire harness is bent, the pressure is transmitted to the auxiliary seat 1011, causing it to slide on the pulling rope 1008 and the spring rod 1010, compressing and stretching the telescopic spring 1009, deforming the spring rod 1010, buffering the stress, ensuring the fixing effect while giving the wire harness the freedom to bend, and completing the fixing adjustment.

[0035] Working principle: When adjusting the fixing of the automotive wire harness, the servo motor 1312 drives the moving part 1311 to rotate. Since the moving part 1311 is connected to the adjusting rope 1309, the rotation of the moving 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 groove holes of the fixed ring part 1301, driving the adjusting ring part 1303 to move along the inner side of the fixed ring part 1301. The movement of the adjusting ring part 1303 drives the annular gear plate 1304, and through the meshing of the tooth grooves, the gear cylinder 1306 rotates on the round rod 1305, making the adjustment smoother and more precise, enhancing the strength and stability. The movement of the adjusting ring part 1303 compresses the spring 1314, and the spring force acts on the outer side of the fixing sleeve 1 through the auxiliary fixing plate 1315 to achieve clamping and fixing, and it can also adaptively adjust according to the size and shape of the fixing sleeve 1 to ensure tight and stable fixing.

[0036] When adjusting the fixing of the wire harness, if the wire harness is relatively long, the fixing range needs to be increased. The driving motor 1004 drives the rotating rod 1003 and the rotating gear 1005 to rotate, thereby causing the gear ring 1006 and the rotating shaft 1007 to rotate, winding the pulling rope 1008, pulling another base 1002 closer, increasing the distance between the bases 1002, stretching the spring rod 1010, and the auxiliary seat 1011 follows and stretches the telescopic spring 1009, always contacting the fixing sleeve 1, achieving a wide-range fixing to adapt to the long wire harness. When the wire harness is bent, the pressure is transmitted to the auxiliary seat 1011, causing it to slide on the pulling rope 1008 and the spring rod 1010, compressing and stretching the telescopic spring 1009, deforming the spring rod 1010, buffering the stress, ensuring the fixing effect while giving the wire harness the freedom to bend, and completing the fixing adjustment.

[0037] After the wire harness is fixed, the magnetic plate is adsorbed inside the vehicle. When the main magnetic plate 9 and the auxiliary magnetic plate 6 are initially adsorbed and it is necessary to increase the magnetic adsorption area, the bidirectional telescopic drive rod 4 extends, pushing the fixed frame 5 to move outward. The telescopic bidirectional rod 7 extends synchronously to ensure stability and synchronism. The auxiliary magnetic plate 6 moves outward with the fixed frame 5, increasing the distance between the main magnetic plate 9 and the auxiliary magnetic plate 6, expanding the magnetic adsorption coverage area, and enhancing the fixing stability. During the movement of the fixed frame 5, the telescopic rod 11 guides the fixing member 3 and the base 1002 to move linearly, and the buffer spring 12 absorbs the moving impact force.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
