Description

[0001] The present disclosure relates to the technical field of vehicles, and in particular to a wire harness filter device and a vehicle. Background Art

[0002] During the operation of the entire vehicle, the high-voltage DC wiring harness on the electric vehicle will generate or couple to low-frequency interference (hundreds of kHz) and high-frequency interference (tens of MHz). In order to suppress the low-frequency interference and high-frequency interference on the high-voltage DC wiring harness, magnetic materials of different materials are required for comprehensive filtering.

Generally, multiple different filtering devices are required to achieve this. The magnetic permeabilities of the internal magnetic materials of the multiple filtering devices are different, so that different filtering devices can suppress different frequency interferences, thereby taking into account high and low frequency filtering.

[0029] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0031] The wiring harness filter device and the vehicle disclosed in the present invention are described in detail below through specific embodiments:

[0032] Reference Figures 1 to 3 As shown, a wiring harness filter device and a vehicle provided by an embodiment of the utility model include a shell 1, on which a plurality of wiring harness vias 11 are arranged, and the plurality of wiring harness vias 11 all pass through both ends of the shell 1 in the axial direction so that different wiring harnesses can pass through different wiring harness vias 11 accordingly.

[0033] In specific implementation, a partition 12 is provided inside the shell 1 to separate the internal space of the shell 1 into a first filter layer 13 and a second filter layer 14 sequentially distributed along the axial direction of the shell 1, that is, the shell 1 forms a double-layer filter structure.

[0034] Furthermore, a first magnetic ring 2 and a second magnetic ring 3 are formed on the first filter layer 13 and the second filter layer 14. There are multiple first magnetic rings 2 and they are arranged one by one corresponding to the multiple wiring harness vias 11. Each first magnetic ring 2 is arranged around the periphery of the corresponding wiring harness via 11 to suppress the differential mode interference between different wiring harnesses through the first magnetic ring 2. The second magnetic ring 3 is arranged around the periphery of all the first magnetic rings 2, that is, the second magnetic ring 3 is arranged around the periphery of all the wiring harness vias 11, so that the common mode interference on all wiring harnesses can be suppressed by the second magnetic ring 3, thereby taking into account both the common mode interference and the differential mode interference on the wiring harness.

[0035] Specifically, the first magnetic ring 2 and the second magnetic ring 3 on the first filter layer 13 and the second filter layer 14 can select different magnetic materials and combine the magnetic materials according to actual needs, so as to achieve targeted filtering, so as to achieve common-differential mode integrated filtering while taking into account high and low frequency filtering interference. The wire harness filter device disclosed in the present invention can achieve full-band targeted filtering and common-differential mode integrated filtering only by forming the first magnetic ring 2 and the second magnetic ring 3 on the first filter layer 13 and the second filter layer 14, so as to reduce the electromagnetic interference generated by the high-voltage DC system, ensure the normal operation of the surrounding low-voltage sensitive equipment, and thus reduce the external radiation of the whole vehicle. Compared with the solution of using multiple different wire harness filter devices, it can save space, have high filtering efficiency and low cost.

[0036] It should be noted that when filtering is required for three, four or more frequency bands, it can be achieved by superimposing multiple wire beam filtering devices. Specifically, the wire beam filtering device can only fill one of the first filter layer 13 and the second filter layer 14 to meet the use requirements of multi-band filtering.

[0037] In some embodiments, reference Figure 1 As shown, the first filter layer 13 and the second filter layer 14 are both provided with a plurality of first wall surfaces 15 and a plurality of second wall surfaces inside, the plurality of first wall surfaces 15 and the plurality of second wall surfaces are annular wall surfaces and are arranged one by one, the second wall surface is formed as the inner wall surface of the harness via hole 11, and each first wall surface 15 is arranged around the periphery of the corresponding second wall surface. It can be understood that the shape of the second wall surface, i.e., the harness via hole 11, is adapted to the shape of the harness, and the harness via hole 11 is formed as a cylindrical barrel hole, and the first wall surface 15 is formed as an annular sleeve structure, so that the first wall surface 15 can be arranged around the periphery of the second wall surface, i.e., the harness via hole 11.

[0038] In a specific implementation, each second wall surface, i.e., the periphery of the harness via hole 11, is surrounded by a first wall surface 15, and a first cavity is formed between each first wall surface 15 and the corresponding second wall surface, and each first cavity is filled with a first magnetic material to form a first magnetic ring 2. In other words, each harness via hole 11 is surrounded by a first magnetic ring 2, so that the differential mode interference between the harnesses in the plurality of harness via holes 11 can be suppressed by a plurality of first magnetic rings 2. Specifically, the first magnetic material is an iron powder material or an amorphous material, etc., and is used to suppress low-frequency differential mode interference.

[0039] Of course, it should be noted that the second wall surface can also be spaced apart from the inner wall surface of the wiring harness via 11, and a plastic filler 6 can be filled between the second wall surface and the inner wall surface of the wiring harness via 11. The present disclosure does not limit this, as long as a first magnetic ring 2 can be formed between the first wall surface 15 and the second wall surface and the first magnetic ring 2 can be sleeved on the periphery of the wiring harness via 11 to suppress differential mode interference between the wiring harnesses in multiple wiring harness vias 11.

[0040] Furthermore, a third wall 16 is provided inside the first filter layer 13 and the second filter layer 14. The third wall 16 is an annular wall and is arranged around the periphery of all the first walls 15. In specific implementation, the first wall 15, the second wall and the third wall 16 are all extended along the axial direction of the multiple wiring harness vias 11, so that the third wall 16 can be arranged around the periphery of all the first walls 15.

[0041] The third wall surface 16 is arranged around the periphery of all the first wall surfaces 15, that is, the third wall surface 16 is arranged around the periphery of all the wiring harness via holes 11, and a second cavity is formed between each third wall surface 16 and the outer wall surface of the housing 1, and each second cavity is filled with a second magnetic material to form a second magnetic ring 3. In this way, the second magnetic ring 3 can suppress the common mode interference on all wiring harnesses, and then combined with the first magnetic ring 2, the common mode interference and differential mode interference on the wiring harness can be taken into account.

[0042] Specifically, the second magnetic material is a material such as manganese zinc ferrite with high magnetic permeability, a high magnetic permeability nanocrystalline material, or a material such as nickel zinc ferrite with low magnetic permeability, a low magnetic permeability nanocrystalline material, etc., which can be diversified according to actual needs to achieve targeted filtering. In specific implementation, the first wall surface 15 and the third wall surface 16 on the first filter layer 13 and the second filter layer 14 can be aligned, or the size can be specifically set according to actual needs, which is not limited in the present disclosure.

[0043] Reference Figure 1 As shown, the outer wall surface of the shell 1 is formed into a columnar structure with an elliptical cross-section, so that multiple wiring harnesses can pass through the wiring harness vias 11 on the shell 1. Correspondingly, the second magnetic ring 3 is formed into an annular magnetic ring adapted to the shape of the shell 1, and the cross-section of the second magnetic ring 3 is formed into an elliptical circular ring to surround the periphery of the multiple wiring harness vias 11, that is, to surround the periphery of the multiple first magnetic rings 2.

[0044] It should be noted that the first wall 15 and the third wall 16 can also be wall structures of other shapes, and the present disclosure does not limit this. As long as a first cavity can be formed between the first wall 15 and the wiring harness via 11 to form a first magnetic ring 2, and a second cavity can be formed between the third wall 16 and the outer wall of the shell 1 to form a second magnetic ring 3, common and differential mode integrated filtering can be achieved.

[0045] In some embodiments, reference Figure 2 As shown, a plastic filler 6 is filled between the first wall 15 and the third wall 16 to improve the structural strength of the housing 1 of the wiring harness filter device through the plastic filler 6. That is, a plastic filler 6 is provided between the first wall 15 and the third wall 16, a first magnetic material is provided between the first wall 15 and the wiring harness via 11, and a second magnetic material is provided between the third wall 16 and the outer wall of the housing 1, so that the interior of the housing 1 is formed into a solid structure to ensure the structural strength of the wiring harness filter device and ensure the service life.

[0046] In a specific implementation, the gaps of the first magnetic material filled in the first cavity and the gaps of the second magnetic material filled in the second cavity are filled with solidified materials. It can be understood that by filling the solidified materials into the gaps of the first magnetic material and the gaps of the second magnetic material respectively, the first magnetic material can be fixed in the first cavity and the second magnetic material can be fixed in the second cavity, so as to prevent the first magnetic material and the second magnetic material from shaking or leaking out of the housing 1 due to bumps during the driving of the vehicle, thereby ensuring the performance of the wiring harness filter device. Specifically, the solidified material is a material such as resin.

[0047] Specifically, the housing 1 and the separator 12 are injection molded into an integrated plastic structure to prevent leakage problems. Specifically, the separator 12 is a plate-like structure formed inside the housing 1 to separate the internal space of the housing 1 into a first filter layer 13 and a second filter layer 14. It should be noted that the wire harness filter device disclosed in the present invention needs to be filled twice during production. First, the first filter layer 13 is placed upward, and the first magnetic material is filled in the first cavity of the first filter layer 13, and the second magnetic material is filled in the second cavity of the first filter layer 13. After the filling is completed, the first magnetic material and the second magnetic material are fixed by filling the solidifying material, and then the upper cover 4 is covered, thereby forming the first magnetic ring 2 and the second magnetic ring 3 on the first filter layer 13.

[0048] Then, the shell 1 is turned over so that the second filter layer 14 is set upward, and the first cavity of the second filter layer 14 is filled with the first magnetic material and the second cavity of the second filter layer 14 is filled with the second magnetic material. After the filling is completed, the first magnetic material and the second magnetic material are fixed by filling with solidifying material, and then the upper and lower covers are covered to form the first magnetic ring 2 and the second magnetic ring 3 on the second filter layer 14.

[0049] In specific implementation, the magnetic permeabilities of the magnetic materials of the first filter layer 13 and the second filter layer 14 are different, so that the first filter layer 13 and the second filter layer 14 can filter high-frequency interference and low-frequency interference respectively. It can be understood that the first magnetic material and the second magnetic material of the first filter layer 13 and the second filter layer 14 can select different magnetic materials according to actual needs, and targeted filtering of the entire frequency band can be achieved through the selection and combination of different magnetic materials.

[0050] Furthermore, the plastic filler 6 can be formed integrally during the injection molding of the shell 1 and the partition 12, or can be formed again by injection molding after the shell 1 and the partition 12 are molded. The present disclosure does not limit this, as long as the plastic filler 6 can be used to fill the internal space of the shell 1 to improve the structural strength of the wiring harness filter device.

[0051] Specifically, the wiring harness via 11 has an interference fit with the wiring harness passing through the wiring harness via 11, that is, the diameter of the wiring harness via 11 is the same as the diameter of the wiring harness passing through the wiring harness via 11, or the diameter of the wiring harness via 11 can also be slightly smaller than the diameter of the wiring harness, so as to increase the friction between the wiring harness and the wiring harness via 11, so as to prevent the housing 1 from shaking relative to the wiring harness when the wiring harness passes through the wiring harness via 11, thereby making the position of the wiring harness and the wiring harness filter device relatively fixed, avoiding the shaking of the wiring harness during vehicle driving.

[0052] It should be noted that the diameter of the wire harness via 11 may be larger than the diameter of the wire harness so that the wire harness can pass through the wire harness via 11 . The present disclosure does not limit this and it may be specifically set according to actual needs.

[0053] In some embodiments, reference Figure 3 As shown, the wiring harness filtering device also includes an upper cover 4 and a lower cover. The upper cover 4 is detachably arranged on the top of the shell 1, and the lower cover is detachably arranged on the bottom of the shell 1, so that the interior of the shell 1 is formed into a closed space, and then the first magnetic material and the second magnetic material are filled in the shell 1 to form a first magnetic ring 2 and a second magnetic ring 3, so as to realize full-band targeted filtering and common-differential mode integrated filtering.

[0054] Specifically, the upper cover 4 and the lower cover are both provided with openings 41 at positions corresponding to the harness through-holes 11, so that the harness can pass through the openings 41 and the harness through-holes 11, and then the housing 1 is fixed on the harness, and then the harness is filtered through the first magnetic ring 2 and the second magnetic ring 3. In specific implementation, the upper cover 4 and the lower cover can be respectively arranged on the top and bottom of the housing 1 by means of snap connection or bonding, and the present disclosure does not limit this, as long as the upper cover 4 and the lower cover can be fixed on the housing 1, and the first magnetic material and the second magnetic material can be prevented from leaking out to ensure the service life of the harness filter device.

[0055] In some embodiments, the wire harness filter device also includes a mounting angle 5, which is arranged on the outer wall of the shell 1, and a mounting through hole 51 is arranged on the mounting corner 5. The wire harness filter device is fixed by a fastener passing through the mounting through hole 51. When the wire harness filter device is fixed to the body of the vehicle, the shell 1 and the wire harness can be prevented from shaking during the driving of the vehicle, thereby improving the space utilization.

[0056] It should be noted that the housing 1 can also be fixed to the vehicle body by other fixing methods, such as bonding or clamping, etc., and the present disclosure does not limit this, as long as the housing 1 and the wiring harness can be prevented from shaking during the driving of the vehicle.

[0057] Other embodiments of the present disclosure provide a vehicle, including a wire harness and a wire harness filter device as described in any of the above embodiments, wherein the wire harness passes through a wire harness through hole 11 of the wire harness filter device and can provide running power to the vehicle.

[0058] The vehicle provided in the embodiment of the present disclosure includes the wiring harness filter device of any of the above embodiments, and thus has the beneficial effects of the wiring harness filter device of any of the above embodiments, which will not be described in detail here.

[0059] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the term "comprises" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0060] The above description is only a specific embodiment of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
