DETAILED DESCRIPTION

[0030] In order to make the person skilled in the art to which the present application belongs more clearly understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] In addition, the reference numbers and / or reference letters can be repeated in different examples in the present application, and such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but the person skilled in the art can realize the application of other processes and / or the use of other materials.

[0032] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0033] The embodiment of the present application discloses a harness fixing device 1000, which can solve the technical problem that the existing high-voltage harness fixing device is easily damaged by vibration due to rigid fixation, improve the service life and performance of the harness, and enhance the safety and stability of vehicle operation.

[0034] The technical solutions of the present application will be described in detail below through specific embodiments:

[0035] Reference Figure 1 In the first aspect of the present application, a harness fixing device 1000 is disclosed, which comprises a center positioning ring 100, a connecting structure 300 and two or more support rings 200. The support rings 200 are arranged at intervals on the outer circumferential side of the center positioning ring 100. The connecting structure 300 comprises a connecting piece 310 and an elastic support 320, the two ends of the elastic support 320 are connected with the adjacent two support rings 200 respectively, and the two ends of the connecting piece 310 are connected with the positioning ring and the elastic support 320 respectively.

[0036] The wire harness fixing device 1000 disclosed in the embodiment connects each support ring 200 and the center positioning ring 100 together through the connecting structure 300. Since the connecting structure 300 includes the elastic support 320 with a certain elasticity, the position between the support ring 200 and the center positioning ring 100 can be finely adjusted. The high-voltage wire harness 2000 is arranged in the center positioning ring and the support ring 200 respectively. When the high-voltage wire harness 2000 slides due to the influence of external factors when the vehicle is jolted, the elastic support 320 allows each high-voltage wire harness 2000 to swing within a certain range, thereby avoiding that the high-voltage wire harness 2000 directly damages the wire harness fixing device 1000 when swinging. After the vehicle stops jolting, the elastic support 320 quickly brings the high-voltage wire harness 2000 back to the original position in order to restore the original shape.

[0037] Referring to Figure 1 and Figure 2 In an embodiment, the elastic support 320 is made in an arc shape, so that the support rings 200 connected to the two ends of the elastic support 320 can be symmetrically arranged relative to the center positioning ring 100. When the elastic support 320 is arranged in more than three, the arc-shaped elastic support 320 can arrange each support ring 200 in a ring shape along the circumference of the center positioning ring 100, so as to make each high-voltage wire harness 2000 more compact and reduce the space occupied by the high-voltage wire harness 2000.

[0038] In an embodiment, the connecting member 310 is a telescopic structure. When the connecting member 310 is elongated, the elastic support 320 drives the two support rings 200 to move towards the center positioning ring 100. Initially, the connecting member 310 is in a shortened state, at this time, the support ring 200 has a certain distance from the center positioning ring 100, which is convenient for installing the high-voltage wire harness 2000. After the high-voltage wire harness 2000 is installed, the connecting member 310 is elongated, at this time, the support ring 200 drives the high-voltage wire harness 2000 to move towards the high-voltage wire harness 2000 located in the center positioning ring 100.

[0039] Referring to Figure 1 and Figure 3 In an embodiment, the connecting member 310 includes a mounting seat 311, a first adjusting rod 312, a second adjusting rod 313 and a connecting block 314. The mounting seat 311 is mounted on the center positioning ring 100, and the first adjusting rod 312 is mounted on the mounting seat 311. The second adjusting rod 313 is in sliding fit with the first adjusting rod 312, the connecting block 314 is connected with one end of the second adjusting rod 313 away from the first adjusting rod 312, and the connecting block 314 is connected with the elastic support 320.

[0040] By controlling the relative position of the first adjusting rod 312 and the second adjusting rod 313, the overall length of the connecting member 310 can be changed, so as to achieve the purpose of elongation or contraction.

[0041] In one embodiment, the first adjusting rod 312 is rotationally connected with the mounting base 311, and the rotation axis between the first adjusting rod 312 and the mounting base 311 is parallel to the axis of the center positioning ring 100. When the high-voltage wire harness 2000 is installed, since each high-voltage wire harness 2000 is installed in sequence, the elastic support 320 may be offset during the installation process. The rotation of the first adjusting rod 312 and the mounting base 311 can adapt to the offset of the elastic support 320, thereby avoiding damage to the connecting piece 310 or the elastic support 320, and at the same time, the offset elastic support 320 also makes the installation of the high-voltage wire harness 2000 more convenient.

[0042] In one embodiment, the end of the first adjusting rod 312 away from the mounting base 311 is provided with a threaded hole, the outer wall of the second adjusting rod 313 is provided with an external thread, the second adjusting rod 313 is threadedly connected with the first adjusting rod 312, and the connecting block 314 is rotationally connected with the second adjusting rod 313. When the total length of the connecting piece 310 needs to be adjusted, the second adjusting rod 313 is only needed to be rotated to realize the elongation or shortening of the connecting piece 310, and the thread generally has self-locking property. After the total length of the connecting piece 310 is adjusted to the appropriate position, the position of the second adjusting rod 313 and the first adjusting rod can be fixed by using the self-locking property of the thread, thereby realizing the position fixation of the elastic support 320 and the support ring 200.

[0043] Of course, the threaded connection between the first adjusting rod 312 and the second adjusting rod 313 is only one embodiment in the present embodiment, and in other embodiments, a sliding groove and a sliding block or the like can be arranged between the second adjusting rod 313 and the first adjusting rod 312 to realize the sliding between the second adjusting rod 313 and the first adjusting rod 312.

[0044] In one embodiment, the number of elastic support members 320, support rings 200, and connectors 310 are all the same. In this case, each support ring 200 and each elastic support member 320 is sequentially distributed along the circumference of the center positioning ring 100, and the support rings 200 and the elastic support members 320 are staggered, that is, each support ring 200 is connected to an elastic support member 320 on both sides, and each elastic support member 320 is also connected to a support ring 200 at both ends, and each elastic support member 320 is connected to the center positioning ring 100 via a connector 310. When the connecting member 310 is shortened, the arc-shaped elastic support member 320 tends to straighten, and therefore, the support rings 200 located at both ends of the elastic support member 320 tend to move away from the center positioning ring 100; and when the connecting member 310 is extended, the connecting member 310 causes the elastic support member 320 to have a tendency to increase the bending amplitude, and therefore, the support rings 200 located at both ends of the elastic support member 320 tend to move toward the direction ring close to the center positioning.

[0045] In one embodiment, the elastic support member 320 is made of rubber. The elastic support member 320 made of rubber has a certain degree of deformation capability and tends to automatically restore its original shape after a certain deformation, thereby preventing the elastic support member 320 from being directly damaged when the high-voltage wire harness 2000 swings. When the length of the connecting member 310 changes, the elastic support member 320 made of rubber can also quickly change shape according to the length of the connecting member 310.

[0046] See Figure 1 and Figure 2 In another embodiment, the elastic support member 320 includes a flexible column 321 and a spring 322. The end of the connecting member 310 facing away from the center positioning ring 100 is connected to the flexible column 321. The spring 322 is sleeved outside the flexible column 321, and the two ends of the spring 322 are respectively connected to the two support rings 200. The spring 322 can be used to drive the two support rings 200 away from each other.

[0047] The provision of spring 322 can achieve the same effect as the rubber elastic support member 320. However, since the direction of the thrust of the curved spring 322 is uncertain, a flexible column 321 is provided to guide the elastic force of the spring 322, ensuring that the elastic force of the spring 322 acts precisely on the two support rings 200. This allows the wiring harness to swing within a certain range when the vehicle is jolted, and the high-voltage wiring harness 2000 to quickly return to its predetermined position after the vehicle stops jolting.

[0048] See Figure 1 、 Figure 3 and Figure 4In one embodiment, the outer support 130 and the inner support 120 are arranged on the center positioning ring 100. The inner support 120 is mounted on the outer wall of the center positioning ring 100, the outer support 130 is connected with the inner support 120, and the outer support 130 is located between the center positioning ring 100 and the support ring 200, and the outer surface of the outer support 130 abuts against the support ring 200. The inner support 120 is deformed by heat to drive the outer support 130 to move away from the center positioning ring 100.

[0049] The inner support 120 is in the shape of a strip or a plate, and the two ends thereof are connected with the center positioning ring 100 respectively, but the middle part thereof is arranged in a spaced manner with the center positioning ring 100, and the outer support 130 is connected with the middle part of the inner support 120. When the inner support 120 is deformed by heat, the middle part thereof will protrude outward because the two ends thereof are fixed, thereby pushing the outer support 130 to move outward and further pushing the support ring 200 to move away from the center positioning ring 100. At this time, the gap between the high-voltage wire harnesses 2000 can be increased, thereby increasing the heat dissipation efficiency.

[0050] In one embodiment, the two ends of the inner support 120 are welded on the outer wall of the center positioning ring 100. The welding can make the inner support 120 and the center positioning ring 100 more firmly connected, and make the inner support 120 and the center positioning ring 100 form an integral structure, so that the heat of the center positioning ring 100 can be transferred to the inner support 120 more quickly.

[0051] The center positioning ring 100 and other components in the wire harness fixing device 1000 can be made of metal. The metal material has higher structural strength, and only needs to be non-magnetic.

[0052] In one embodiment, the inner support 120 can be a copper sheet with good ductility and large thermal expansion coefficient, and the outer support 130 can be a steel sheet with high structural strength and small thermal expansion coefficient. In addition to pushing the support ring 200 away from the center positioning hole, the outer heat dissipation sheet also has the effect of heat insulation, avoiding the support ring 200 from absorbing the heat of the inner support 120, so that the inner support 120 can maintain sufficient curvature and avoid affecting the heat dissipation of the center positioning ring 100.

[0053] In an embodiment, the center positioning ring 100 is provided with heat dissipation holes 110, and the positions of the heat dissipation holes 110 correspond to the positions of the inner support 120. The heat dissipation holes 110 can help the high-voltage wire harness 2000 in the center positioning ring 100 dissipate heat faster, and the heat in the center positioning ring 100 can flow in a specified direction through the heat dissipation holes 110. The heat dissipation holes 110 arranged towards the inner support 120 can make the heat be absorbed by the inner support 120 more directly and quickly, so that the inner support 120 deforms quickly and pushes the support ring 200 away from the center positioning ring 100.

[0054] In an embodiment, each support ring 200 corresponds to at least one inner support 120 and one outer support 130, that is, the center positioning ring 100 is provided with at least one inner support 120 and one outer support 130 at the position corresponding to each support ring 200, and one heat dissipation hole 110 is arranged at the position of each inner support 120. When the high-voltage wire harness 2000 works and heats up, the inner support 120 and the outer support 130 can simultaneously push each support ring 200 away from the center positioning ring 100, thereby improving the heat dissipation efficiency.

[0055] In an embodiment, a plurality of heat dissipation holes 110, inner supports 120 and outer supports 130 are uniformly arranged on the peripheral wall of the center positioning ring 100. After the high-voltage wire harness 2000 is installed in the center positioning ring 100 and the support rings 200, the position of the support ring 200 may

[0056] In an embodiment, the inner support 120 and the outer support 130 are both arc-shaped, and the center of the inner support 120 is located in the heat dissipation hole 110. The curvature radius of the outer support 130 is greater than that of the inner support 120.

[0057] The center of the inner support 120 located in the heat dissipation hole 110 can make the heat sprayed from the heat dissipation hole 110 be sprayed more uniformly on the inner support 120, so that the temperature of each part of the inner support 120 is more uniform, thereby making the inner support 120 push the outer support 130 and the support ring 200 away from the center positioning ring 100 more accurately when deforming, avoiding that the inner support 120 pushes the outer support 130 to other directions due to uneven heating, so that the position between the support ring 200 and the center positioning ring 100 does not change or the distance away is limited.

[0058] The curvature radius of the outer support member 130 is greater than the curvature radius of the inner support member 120, which can ensure that the outer support member 130 is connected to the inner support member 120 only in the middle position, and its end is not connected to the center positioning ring 100, thereby ensuring that the inner support member 120 can quickly push the outer support member 130 to move when deformation occurs.

[0059] In one embodiment, a rotating ring 210 is provided in the support ring 200, and the rotating ring 210 is rotatably connected to the support ring 200. During the operation of the vehicle, when the vehicle is bumpy and the charging harness is affected by external factors and shakes, the high-voltage harness 2000 will not only have a certain degree of displacement, but also a distortion. The rotating ring 210 rotatably connected to the support ring 200 allows the high-voltage harness 2000 in the support ring 200 to rotate relative to the support ring 200, thereby reducing the force exerted by the high-voltage harness 2000 on the support ring 200, thereby preventing the high-voltage harness 2000 from damaging the support ring 200 when the vehicle is bumpy.

[0060] Through the above-described embodiments, the present application has the following beneficial effects or advantages: The wire harness fixture 1000 disclosed in the present application, through the elastic support member 320 and the retractable connector 310, can effectively buffer the vibration caused by the shaking of the high-voltage wire when the vehicle encounters bumps during driving, thereby preventing damage to the wire harness fixture 1000 due to rigid fixation, thereby improving the reliability and service life of the device. The heat dissipation holes 110 provided on the center positioning ring 100 and the special design of the inner and outer support members 130 allow heat generated by the wire harness to be transferred to the inner support member 120 through the heat dissipation holes 110. The deformation of the inner support member 120 due to heat drives the movement of the outer support member 130, increasing air circulation space, facilitating heat dissipation from the wire harness, preventing safety issues caused by overheating, and improving the performance and service life of the wire harness. The retractable function of the connector 310 and the rotating connection design of the support ring 200 and the rotating ring 210 enable the wire harness fixture 1000 to adapt to different wire harness fixation requirements, reduce stress caused by torsion in the wire harness, further protect the wire harness, and improve the versatility and adaptability of the device.

[0061] See Figure 5 and Figure 6 Based on the same inventive concept, the second embodiment of the present application discloses a vehicle, which includes a vehicle body, a high-voltage electrical device, a high-voltage wire harness 2000, and the wire harness fixture 1000 disclosed in any embodiment of the first aspect. One end of the high-voltage wire harness 2000 is electrically connected to the high-voltage electrical device via a compatible connector 3000. The high-voltage wire harness 2000 is disposed within the wire harness fixture 1000. The other end of the high-voltage wire harness 2000 is fixed to the vehicle body via an electronic control assembly 5000. The high-voltage wire harness 2000 is electrically connected to the electronic control assembly 5000 via a connecting connector 4000.

[0062] The vehicle provided with the wire harness fixing device 1000 disclosed in the embodiment can effectively protect the high-voltage wire harness 2000, reduce electrical faults caused by damage of the wire harness fixing device 1000 or overheating of the wire harness, and enhance the safety and stability of vehicle operation.

[0063] When the high-voltage wire harness 2000 is installed on the wire harness fixing device 1000 disclosed in the application, the center positioning ring 100 is first fixed at a suitable position of one high-voltage wire harness 2000, and the remaining high-voltage wire harnesses 2000 are also respectively passed through the corresponding support rings 200. By adjusting the connecting piece 310 fixedly connected outside the center positioning ring 100, the elastic support piece 320 connecting the two support rings 200 is deformed, and the support ring 200 is tightly attached to the outer support piece 130 and the center positioning ring 100 by the tension provided by the deformed flexible column 321 and the tension spring 322 sleeved outside the flexible column 321. Then, the two ends of the high-voltage wire harness 2000 are connected with the compatible connector 3000 and the connecting connector 4000, respectively, and the connecting connector 4000 is connected with the electronic control assembly 5000.

[0064] During the charging of the vehicle, the high-voltage wire harness 2000 transmits high voltage and large current, and dissipates heat through the heat dissipation holes 110 in the center positioning ring 100. The heat generated by the high-voltage wire harness 2000 is effectively transferred to the inner support piece 120 and the outer support piece 130 through the heat dissipation holes 110. Due to the different thermal expansion coefficients and structural strengths of the inner support piece 120 and the outer support piece 130, the inner support piece 120 expands and bulges, while the outer support piece 130 supports the support ring 200, thereby expanding the gap between the support ring 200 and the center positioning ring 100, and achieving the purpose of dynamic adjustment of the spacing between the plurality of high-voltage wire harnesses 2000, thereby improving the heat dissipation efficiency.

[0065] During the operation of the vehicle, when the vehicle bounces and the high-voltage wire harness 2000 is affected by external factors to produce shaking, the high-voltage wire harness 2000 will displace to a certain extent, including the twisting movement. At this time, the flexible column 321, the tension spring 322 and the connecting piece 310 can play a certain buffering role for the rotating ring 210 and the support ring 200 outside, so as to avoid damage of the high-voltage wire harness 2000 or the wire harness fixing device 1000 due to vibration.
