Description

Technical Field

[0001] The present invention relates to the field of automobile manufacturing, and in particular to a high-voltage wire harness assembly for new energy vehicles. Background Art

[0002] The overall automotive wiring harness can be divided into two types: low-voltage wiring harness and high-voltage wiring harness. Traditional fuel vehicles mainly use low-voltage wiring harnesses, while new energy vehicles mainly use high-voltage wiring harnesses. High-voltage wiring harnesses can be configured in the internal and external wiring harness connections of electric vehicles according to different voltage levels. It is mainly used for internal wiring harness signal distribution in the distribution box, efficient and high-quality transmission of electrical energy, shielding of external signal interference, etc. High-voltage wiring harnesses are the neural network of the high-voltage system of new energy vehicles, which is very important. The high-voltage wiring harness of new energy vehicles is mainly composed of connectors, terminals, wires, coverings and other parts.

[0003] When the high-voltage wire harness used in new energy vehicles is powered on, the structure of the high-voltage wire harness itself can effectively shield external signal interference. When the high-voltage wire harness is damaged, a strong magnetic field will be generated around it. Over time, it is easy to affect the operation of new energy vehicles. In addition, when the vehicle is running, there will be certain bumps. Over time, the high-voltage wire harness and the vehicle body are prone to serious wear and tear, reducing its service life. When installing the existing high-voltage wire harness, in order to avoid the deviation of the wire harness due to vibration, the wire harness needs to be clamped. However, the clamping installation will cause the high-voltage wire harness to be squeezed and deformed, resulting in a smaller cross-sectional area of ​​the high-voltage wire harness, increased resistance, and reduced current transmission efficiency, which not only increases energy loss, but also easily causes the operating temperature of the high-voltage wire harness to increase, reducing the service life of the high-voltage wire harness.

[0019] Compared with the prior art, the present invention provides a high-voltage wiring harness assembly for new energy vehicles, which has the following beneficial effects:

[0020] 1. A high-voltage wire harness assembly for new energy vehicles is provided with a retracting and releasing mechanism.

When the vibration exceeds a certain amplitude, the second motor drives the second threaded rod to rotate, and the second threaded rod drives the adjustment block to move.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, this application proposes a high-voltage wire harness assembly for new energy vehicles.

[0034] like Figure 1-7 As shown, a high-voltage wiring harness assembly for new energy vehicles includes:

[0035] A wiring harness body 1, with connectors 2 installed at both ends of the wiring harness body 1. The wiring harness body 1 is provided with a conductor layer 3, an insulating layer 4, a protective layer 5, a shielding layer 6 and a sheath layer 7 from the inside to the outside. It should be noted that the conductor layer 3 is made of a bare copper conductor material for transmitting high voltage electricity, the insulating layer 4 is made of a cross-linked polyolefin material for preventing high voltage electricity leakage, the protective layer 5 is made of a polyester fiber material, and has the functions of high temperature resistance, waterproofness and moisture resistance, the shielding layer 6 is made of a tinned copper wire material for isolating electromagnetic interference, and the sheath is made of a cross-linked polyolefin material for protecting the inside of the wiring harness body 1;

[0036] In order to avoid excessive friction between the wiring harness body 1 and the vehicle body due to vehicle body vibration, a retracting and releasing mechanism 8 is provided for retracting and releasing the wiring harness body 1. The retracting and releasing mechanism 8 includes a sleeve 9 fixedly sleeved outside the wiring harness body 1, a slip ring 10 is slidably sleeved outside the sleeve 9, a support plate 11 is fixedly welded on the upper end of the slip ring 10, and a vibration sensor is embedded in the support plate 11. It should be noted that the vibration sensor is electrically connected to the second motor 33, and a mounting plate 12 is slidably connected to the upper end of the support plate 11. The mounting plate 12 is provided with an adjusting mechanism 13 for adjusting the support plate 11. It is worth mentioning that the adjusting mechanism 13 includes an adjusting groove provided at the lower end of the mounting plate 12, a second threaded rod 32 is rotatably connected in the adjusting groove, a second motor 33 is installed in the adjusting groove, a driving shaft of the second motor 33 is coaxially fixedly connected to the second threaded rod 32, an adjusting block 34 is provided on the outer thread of the second threaded rod 32, the adjusting block 34 is slidably connected to the inner side wall of the adjusting groove, and the adjusting block 34 is fixedly connected to the support plate 11;

[0037] Through the above technical features: when the vehicle is bumpy, the vibration sensor detects the amplitude of the vehicle vibration. When the vibration exceeds a certain amplitude, the second motor 33 drives the second threaded rod 32 to rotate, and the second threaded rod 32 drives the adjustment block 34 to move. The adjustment block 34 moves through the support plate 11 and the slip ring 10, and the slip ring 10 drives the wiring harness body 1 to move through the sleeve 9, so that the wiring harness body 1 fixed at two points and in contact with the vehicle is appropriately extended. When the wiring harness body 1 vibrates with the vehicle, the length of the wiring harness body 1 between the two fixed points is extended, and the wiring harness body 1 is relatively loose. When vibrating at this time, the wiring harness body 1 changes from the original high-frequency vibration to low-frequency vibration. On the one hand, the friction frequency between the wiring harness body 1 and the vehicle is reduced, and wear is reduced. On the other hand, the length of the wiring harness body 1 is changed, so that the position of the wiring harness body 1 in contact with the vehicle body is changed, thereby extending the service life of the wiring harness body 1.

[0038] In order to maintain the transmission efficiency of the high-voltage wire harness, it is not stuck when it is fixed. When it is subjected to vibration for a long time, the wire harness at the fixed point will have a certain offset. In order to compensate for the offset, a compensation mechanism 14 is provided to compensate for the offset of the wire harness body 1 caused by vibration. The compensation mechanism 14 includes two grooves 15 arranged outside the sleeve 9, and first threaded rods 16 are rotatably installed in the two grooves 15. Threaded blocks 17 are threadedly sleeved on the outside of the two first threaded rods 16. The two threaded blocks 17 are fixedly connected to the sleeve 9, and the two threaded blocks 17 are slidably connected to the inner wall of the groove 15. One end of the two first threaded rods 16 rotates through the sleeve 9. And it is connected by transmission mechanism 18. Further, the transmission mechanism 18 includes two transmission gears 35, and the two transmission gears 35 are respectively coaxially fixedly connected with the two first threaded rods 16. A transmission ring 36 is rotatably connected outside the sleeve 9. The transmission ring 36 is provided with an annular tooth groove meshing with the two transmission gears 35. A first motor 19 is fixedly installed outside the sleeve 9. It should be noted that the first motor 19 is electrically connected to the distance sensor 20. The driving shaft of the first motor 19 rotates through the sleeve 9 and is coaxially fixedly connected with one of the first threaded rods 16. A distance sensor 20 is installed outside the wiring harness body 1 for detecting the distance between the distance sensor 20 and the slip ring 10;

[0039] Through the above technical features: through the distance sensor detection, when the wiring harness body 1 is offset and the distance is far or close, the first motor 19 drives one of the first threaded rods 16 to rotate, and the first threaded rod 16 drives the other first threaded rod 16 to rotate through the transmission ring 36 and the two transmission gears 35. During the rotation of the first threaded rod 16, the sleeve 9 will drive the movement of the sleeve 9 relative to the threaded block 17, and the sleeve 9 drives the wiring harness body 1 to move until it reaches a suitable position, thereby compensating for the length of the wiring harness body 1.

[0040] In order to monitor whether the wiring harness body 1 is damaged in real time and to repair it in time, a monitoring mechanism 21 is set up to monitor whether the wiring harness body 1 is damaged. The monitoring mechanism 21 includes a plurality of rings 22 sleeved on the outside of the wiring harness body 1, and a same T-rail 23 is fixedly sleeved outside the plurality of rings 22. It should be noted that the T-rail 23 is made of soft rubber material and can be deformed along with the bending deformation of the wiring harness body 1. A U-shaped plate 24 is slidably sleeved outside the T-rail 23, and a groove matching the T-rail 23 is provided on the inner wall of the U-shaped plate 24. A rotating groove 25 is provided on the inner walls of both arms of the U-shaped plate 24. A rotating rod 26 is rotatably connected in the rotating groove 25, and a gear 27 is coaxially fixedly connected outside the rotating rod 26. A tooth groove meshing with the gear 27 is provided on the T-rail 23, and a cavity 28 is provided in the U-shaped plate 24. , one end of the two rotating rods 26 rotates through the U-shaped plate 24 and extends to the cavity 28, and the two rotating rods 26 are connected by a gear set 29. It is worth mentioning that the gear set 29 includes two mutually meshing first gears 37, and the two first gears 37 are rotatably connected to the inner wall of the cavity 28. The two rotating rods 26 are coaxially fixedly connected with a second gear 38, and the two second gears 38 are respectively meshed with the two first gears 37. A third motor 39 is installed in the cavity 28. Furthermore, the third motor 39 is electrically connected to the car power supply, and the drive shaft of the third motor 39 is coaxially fixedly connected to one of the first gears 37. The end of the U-shaped plate 24 away from the T-shaped rail 23 is fixedly connected to a cross plate 30, and a probe 31 is installed on the cross plate 30. It should be noted that the probe 31 is connected to an external magnetometer.

[0041] Through the above technical features: when the vehicle power is turned on, the power of the third motor 39 is turned on at the same time, the third motor 39 drives the two first gears 37 to rotate relative to each other, the two first gears 37 drive the two rotating rods 26 to rotate relative to each other through the two second gears 38, the two rotating rods 26 drive the U-shaped plate 24 to move on the T-shaped rail 23 through the two gears 27, the U-shaped plate 24 drives the probe 31 to move through the cross plate 30, the probe 31 can monitor the magnetic field near the wiring harness body 1, when the probe 31 moves to a certain place, when the magnetic field nearby suddenly increases, it means that the wiring harness body 1 here is damaged, and the wiring harness body needs to be repaired and replaced in time to realize real-time monitoring of the wiring harness body 1.

[0042] 1) Operation: When the vehicle is bumpy, the vibration sensor detects the amplitude of the vehicle vibration. When the vibration exceeds a certain amplitude, the second motor 33 drives the second threaded rod 32 to rotate, and the second threaded rod 32 drives the adjustment block 34 to move. The adjustment block 34 moves through the support plate 11 and the slip ring 10, and the slip ring 10 drives the wire harness body 1 to move through the sleeve 9, so that the wire harness body 1 fixed at two points and in contact with the vehicle is appropriately extended.

[0043] 2) Compensation: Through the detection of the distance sensor, when the wiring harness body 1 is offset and the distance is far or close, the first motor 19 drives one of the first threaded rods 16 to rotate, and the first threaded rod 16 drives the other first threaded rod 16 to rotate through the transmission ring 36 and the two transmission gears 35. During the rotation of the first threaded rod 16, the sleeve 9 will drive the movement of the relative thread block 17, and the sleeve 9 drives the wiring harness body 1 to move until it reaches a suitable position, so that the length of the wiring harness body 1 can be compensated.

[0044] 3) Monitoring: When the vehicle power is turned on, the power of the third motor 39 is turned on at the same time. The third motor 39 drives the two first gears 37 to rotate relative to each other. The two first gears 37 drive the two rotating rods 26 to rotate relative to each other through the two second gears 38. The two rotating rods 26 drive the U-shaped plate 24 to move on the T-shaped rail 23 through the two gears 27. The U-shaped plate 24 drives the probe 31 to move through the cross plate 30. The probe 31 can monitor the magnetic field near the wiring harness body 1. When the probe 31 moves to a certain place, it is observed that the magnetic field near the magnetometer display suddenly increases, indicating that the wiring harness body 1 here is damaged and needs to be repaired and replaced in time to realize real-time monitoring of the wiring harness body 1.
