Description

Technical Field

[0001] The invention relates to the technical field of automobile wiring harnesses, and in particular to a vehicle connection wiring harness and a vehicle. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the automotive wiring harness, there would be no automotive circuit. Its role in the whole vehicle is to transmit or exchange the power signal or data signal of the electrical system to realize the functions and requirements of the electrical system. Due to the harsh use environment of the automobile, the temperature resistance, oil resistance, and anti-interference requirements of the wiring harness are high. The automotive wiring harness is made of copper multi-core soft wires. Some soft wires are as thin as hair. Several or even dozens of soft copper wires are wrapped in a plastic round insulating tube polyvinyl chloride. The wiring harness assembly is wrapped with sticky plastic tape. At present, the functions of automobiles are constantly increasing, the electronic control technology is widely used, and there are more and more electrical parts. The number of circuits and power consumption in automobiles have increased significantly. The automotive wiring harness needs to adapt to the multifunctionality of vehicles and the diversification of user needs. The wiring of the body is huge and the processing and assembly process is complicated. The wiring harness becomes thicker and heavier, and the space occupied on the car is gradually expanding. With the continuous development of science and technology and the birth of new energy vehicles, the future development of automotive wiring harnesses will inevitably need to be more lightweight and modular, so that it is more suitable for the internal circuit network of new energy vehicles.

[0003] The existing wiring harnesses are mainly laid out with conventional wires, and there is a situation where they are assembled on the roof interior. As the number of functions increases, the diameter of the wiring harness is getting larger and larger, and the gap requirements between the roof interior and the sheet metal are getting higher and higher, which is not conducive to the passage of the wiring harness. In order to ensure that there is no collision between the wiring harness and the roof interior and cause abnormal noise, the commonly used method is to glue the entire path, which significantly increases the weight of the roof and is not conducive to the dissipation of odors. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a vehicle connection harness and a vehicle, aiming to solve the problems in the prior art that the lines on the roof interior are difficult to route, the harness is heavy, and the amount of glue applied is large.

[0005] The vehicle connection wiring harness proposed in the present invention includes a flat main line composed of FFC or FPC, a partial area of ​​the flat main line is divided into multiple flat branch lines, and the multiple flat branch lines are folded toward one side of the flat main line. One end of the multiple flat wiring harnesses is provided with a connector for connecting to an electrical component in the car, and the other end is connected to the flat branch line.

[0006] The above-mentioned vehicle connection harness replaces the circular harness in the prior art with a flat main line composed of FFC or FPC, so that the wiring space required for the vehicle connection harness on the top of the roof interior is smaller, which is more convenient for the wiring distribution of the harness. Specifically, the lines required for various electrical appliances in the roof interior are gathered and routed through the flat main line. When reaching the corresponding positions of each electrical appliance, the flat main line is divided into multiple flat branches and routed to the corresponding electrical appliance positions. When reaching the corresponding electrical appliance positions, multiple flat harnesses are extended from the flat branches, which are connected to different ports on the electrical appliances through different connectors, thereby realizing the wiring distribution and connection of the vehicle wiring harness. Corresponding to the circular harness, a large area of ​​glue is required to cover the area of ​​the lower half of the circular harness to ensure the connection area and connection strength of the circular harness and the connection. The use of a flat harness can adjust the amount of glue according to the needs, thereby reducing the amount of glue used and reducing the weight. The use of customized tape can also control the amount of glue used, so that the smell of glue is easily dissipated, thereby more effectively controlling the odor properties in the car. Therefore, the present invention solves the problems in the prior art that the lines on the roof interior are difficult to route, the wiring harness is heavy, and the amount of glue applied is large.

[0007] In addition, the vehicle connection harness proposed in the present invention may also have the following additional technical features:

[0024] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] See also Figures 1 to 4 , shown is a vehicle connection harness in an embodiment of the present invention, including a flat main line 10 composed of FFC or FPC, wherein:

[0028] Part of the flat main line 10 is divided into a plurality of flat branch lines 20 , which are folded toward one side of the flat main line 10 . A plurality of flat wire harnesses 30 are provided with a connector 40 for connecting to electrical components in the car at one end, and are connected to the flat branch lines 20 at the other end.

[0029] It can be understood that by replacing the circular wiring harness in the prior art with the flat main line 10 composed of FFC or FPC, the wiring space required for the vehicle connection wiring harness on the top of the roof 60 interior is smaller, which is more convenient for the wiring distribution of the wiring harness. Specifically, the lines required for various electrical appliances in the roof 60 interior are gathered and routed through the flat main line 10. When they reach the corresponding positions of each electrical appliance, the flat main line 10 is divided into multiple flat branch lines 20 for routing to the corresponding electrical appliance positions. When they reach the corresponding electrical appliance positions, multiple flat wiring harnesses 30 are extended from the flat branch lines 20, which are connected to different ports on the electrical appliance through different connectors 40, thereby realizing the routing distribution and connection of the vehicle wiring harness. Corresponding to the circular wiring harness, a large area of ​​glue is required to cover the area of ​​the lower half of the circular wiring harness, ensuring the connection area and connection strength of the circular wiring harness and the connection. The flat wiring harness 30 can be used to adjust the amount of glue according to the needs, thereby reducing the amount of glue and reducing the weight. The use of customized tape can also control the amount of glue, making the smell of glue easily dissipated, thereby more effectively controlling the odor properties in the car. Therefore, the present invention solves the problems of the difficulty of wiring the lines on the interior of the roof 60 in the prior art, the heavy weight of the wiring harness, and the large amount of glue applied.

[0030] It should be noted that by using FFC or FPC as a signal transmission carrier, the overall structure is flat, the layout is flexible, and the space occupancy is small, and the gap between the roof 60 interior and the roof 60 sheet metal can be fully utilized for layout. In the specific implementation, the FFC or FPC is pre-assembled with tape, and the covering layer on the tape can be peeled off during assembly and then it can be bonded to the roof 60 interior. The roof 60 interior and the pre-pressed groove of about 1mm are used for path positioning during FFC / FPC assembly.

[0031] Specifically, the flat main line 10, the flat branch line 20 and the flat wiring harness 30 are provided with adhesives near the side of the car to fix the flat main line 10, the flat branch line 20 and the flat wiring harness 30 on the car. In the specific implementation, the adhesive can be one or more of glue, adhesive, tape and Velcro. The line is fixed to a specific position of the car by setting the adhesive to ensure the stability of the line transmission and prevent the line from being damaged by shaking. In addition, when setting the circular wiring harness in the prior art, it is necessary to first apply glue to the wiring. When setting the circular wiring harness, since the circular wiring harnesses are independent of each other and the outer side of the circular wiring harness is an arc surface with less contact surface with the wiring, it is necessary to set a larger amount of glue so that the glue covers the lower semicircle of the circular wiring harness to increase the contact area between the circular wiring harness and the glue, thereby ensuring the adhesion effect between the circular wiring harness and the wiring. Since the flat main line 10, the flat branch line 20 and the flat wiring harness 30 are composed of multiple flat wires, the main part is coated with glue and connected to the wiring, which can ensure the adhesion effect. In addition, the contact area between their outer side and the wiring is large, which avoids the need to accumulate excess connection transition glue on both sides when the glue contacts the arc contact surface, thereby reducing the amount of glue.

[0032] In addition, a protective member 50 is provided at the connection between the flat main line 10 and the flat branch line 20 and at the connection between the flat branch line 20 and the flat wire harness 30. By way of example and not limitation, in some optional embodiments, a protective member 50 may also be provided at the connection between the flat main line 10 and the flat branch line 20, and the flat main line 10 extends into the protective member 50 from one end of the protective member 50, and is divided into a plurality of flat branch lines 20 in the protective member 50 to extend out of the protective member 50. Since the routing directions of the flat branch line 20 and the flat main line 10 are different, there is a bend at the connection between the flat main line 10 and the flat branch line 20, which makes the structural strength of the connection between the two relatively fragile, so the connection between the two is protected by providing a protective member 50 to increase the service life of the wire harness.

[0033] Specifically, the protective member 50 includes a rectangular shell 51, and through slots 52 are provided at opposite ends of the shell 51. A plurality of partitions 53 are provided on one side of the shell 51 near any through slot 52 to divide the through slot 52 near the side of the partition 53 into a plurality of openings. In a specific implementation, the protective member 50 can be set as a rectangular shell 51 structure, and a plurality of partitions 53 are provided in the shell 51, so that the flat main line 10 extends into the protective member 50 from the end where the partition 53 is not provided, and the flat branch line 20 is allowed to go out from the plurality of openings separated by the partition 53, so that the plurality of flat branch lines 20 are separated from each other and will not interfere with each other to affect the routing distribution.

[0034] In addition, the housing 51 is provided with symmetrically arranged grooves 54 on both sides adjacent to the through slot 52. The grooves 54 are located near one end of the partition 53. The grooves 54, the through slot 52, the opening and the partition 53 divide the interior of the housing 51 into multiple channels with one entrance, and the multiple channels have the same volume. In addition, in the specific implementation, the direction of the flat branch line 20 is not only consistent with the general trend of the flat main line 10, but also has a situation where the flat branch line 20 is very different from the flat main line 10 due to the structural distribution and the length of the line. Therefore, by providing the grooves 54 on both sides of the housing 51, the direction angle of the flat branch line 20 has a large degree of freedom, and the bending part at the connection between the flat branch line 20 and the flat main line 10 is also protected by the protective member 50. There is no need to forcibly press the bending part tightly against the flat main line 10 or the flat branch line 20 so that the deformation of the bending part is too large to affect the service life of the line, and the protective member 50 will limit the activity space of the bending part to ensure the stability of the line.

[0035] Specifically, part of the flat main line 10 is folded to one side to form a flat branch line 20, and the flat branch line 20 partially overlaps with the flat main line 10. In the specific implementation, the flat branch line 20 is formed by dividing part of the flat main line 10 and folding it to one side, so as to ensure that the overall line routing distribution is consistent and reasonable. In addition, the flat wire harness 30 is staggered and vertically connected to the flat branch line 20. Specifically, in actual use, in order to ensure that the connecting harness is as short as possible, reduce the overall weight of the harness, and facilitate the connection of the harness to the electrical appliance, a flat wire harness 30 is usually additionally provided to be vertically connected to the flat branch line 20 to minimize the length of the harness. In addition, in order to avoid excessive bending angles at the vertical connection, which affects the line quality, an additional flat wire harness 30 is provided, rather than the flat branch line 20 being divided and staggered, thereby leaving enough buffer distance to reduce the bending amplitude at the connection between the two, so as to increase the service life of the harness.

[0036] Specifically, each flat wire harness 30 is provided with a fuse near the flat branch line 20, and the fuse is used to connect the corresponding flat wire harness 30 and the flat branch line 20. By providing the fuse, each electrical circuit is separated, and a short circuit or damage to a single electrical circuit has no effect on the adjacent circuit and its corresponding electrical appliance. In addition, the fuse is provided on one side of the flat branch line 20 to avoid excessive concentration of fuses, which leads to a decrease in the strength of the wiring harness, and to reduce the phenomenon that a single fuse affects the normal operation of adjacent fuses when it is blown and causes the fuse to blow.

[0037] In addition, the vehicle connection harness includes a plurality of flat main lines 10, which are stacked up and down, and adhesives are provided between adjacent flat main lines 10. In addition, in actual use, there are also situations where a vehicle is provided with more functions and a corresponding number of power modules, so a plurality of flat main lines 10 can be stacked up and down to reduce the difficulty of wiring, avoid too many wiring grooves 54 in the door, and increase the difficulty of vehicle design and processing.

[0038] In summary, the vehicle connection harness in the above-mentioned embodiment of the present invention replaces the circular harness in the prior art with a flat main line 10 composed of FFC or FPC, so that the wiring space required for the vehicle connection harness on the top of the roof 60 interior is smaller, which is more convenient for the wiring distribution of the harness. Specifically, the lines required for various electrical appliances in the roof 60 interior are gathered and routed through the flat main line 10, and then when they reach the corresponding positions of each electrical appliance, the flat main line 10 is divided into multiple flat branch lines 20 for routing to the corresponding electrical appliance positions, and then when they reach the corresponding electrical appliance positions, multiple flat wiring harnesses 30 are extended from the flat branch lines 20, which are respectively connected to different ports on the electrical appliance through different connectors 40, thereby realizing the routing distribution and connection of the vehicle wiring harness. Corresponding to the circular wiring harness, a large area of ​​glue is required to cover the area of ​​the lower half of the circular wiring harness, ensuring the connection area and connection strength of the circular wiring harness and the connection. The flat wiring harness 30 can be used to adjust the amount of glue according to the needs, thereby reducing the amount of glue and reducing the weight. The use of customized tape can also control the amount of glue, making the smell of glue easily dissipated, thereby more effectively controlling the odor properties in the car. Therefore, the present invention solves the problems of the difficulty of wiring the lines on the interior of the roof 60 in the prior art, the heavy weight of the wiring harness, and the large amount of glue applied.

[0039] In addition, the present invention also provides a vehicle, which includes the above-mentioned vehicle connection harness and a roof 60, wherein the top plate of the roof 60 is recessed inwardly to have a recessed groove adapted to the connection harness, so that the connection harness can be routed on the roof 60 through the recessed groove.
