Description

Technical Field

[0001] The utility model relates to the technical field of automobile wires, in particular to a multifunctional optical fiber integrated wire structure applied to new energy vehicles. Background Art

[0002] With the continuous development of the "new four modernizations" of automobiles and the increasing demand of consumers for "intelligence, automation, and networking", automobile manufacturers are constantly adding new services to meet the needs of users. The higher the degree of automation of automobiles, the more ECUs need to be installed on the automobile to meet the needs. The addition of a large number of ECUs will lead to an increase in the number of automobile network ports and the amount of data transmitted, making the traditional vehicle communication bus unable to meet the transmission requirements; in addition, under the premise that the volume of the whole vehicle remains unchanged, with the increase in the number of ECUs, the connection harnesses between ECUs and sensors will also increase, which will cause increasing pressure on the space inside the car, resulting in a reduction in the space inside the car. At the same time, as the "nerves and blood vessels" that connect the functions of the whole vehicle in series, the automobile wiring harness is also facing more stringent environmental challenges and cost requirements. On the one hand, the increase in the automation functions of automobiles will lead to an increase in the number of wiring harnesses, an increase in volume, and compression of the space inside the car. On the other hand, due to the pressure of cost, the wiring harness is also required to reduce production costs through the "automated" production mode.

[0003] Patent No. CN207397738U discloses a comprehensive cable, which includes a cable skeleton, optical fibers and wires arranged in the cable skeleton, a waterproof layer coated on the outside of the cable skeleton, a reinforcement layer coated on the outside of the waterproof layer, and a sheath layer arranged on the outside of the reinforcement layer; the optical fiber includes an optical fiber skeleton, an optical fiber ribbon arranged in the optical fiber skeleton, a fixed sleeve coated on the outside of the optical fiber skeleton, and a nylon sheath arranged on the outside of the fixed sleeve; the wire includes a positive wire and a negative wire, the positive wire and the negative wire have the same structure, and the positive wire and the negative wire both include a water pipe, a conductor arranged along the circumference of the water pipe, and a wire sheath coated on the outside of the conductor. However, when the wires are arranged on the car, the cross-sectional area of ​​the wires is large and cannot pass through the narrow area on the car, resulting in the wires being unsuitable for car wire arrangement. In addition, when the wires are arranged and assembled, the wires are loose and soft, which makes it inconvenient to assemble the wires, affecting the assembly efficiency. Utility Model Content

[0004] The utility model provides a multifunctional optical fiber integrated conductor structure for new energy vehicles, which solves the problems in the prior art that the cable has a large cross-sectional area and cannot pass through a narrow area on the vehicle, and the conductor is loose and soft and is not conducive to conductor assembly.

[0005] The technical solution of the utility model is achieved in this way:

[0006] A multifunctional optical fiber integrated wire structure used in new energy vehicles includes an injection molded body, on which ordinary wires and / or optical fiber wires are integrally connected, and two adjacent injection molded bodies are detachably connected.

[0013] The positioning protrusion structure is a dovetail guide rail, the positioning groove structure is a dovetail groove, the dovetail guide rail is slidably connected to the dovetail groove, and the cooperation between the dovetail guide rail and the dovetail groove can realize the fixation of the relative positions of the two injection molding bodies.

[0014] The common wires and the optical fiber wires are arranged in parallel with each other. The common wires and the optical fiber wires extend out of the front and back of the injection molded body, which facilitates the subsequent connection of the common wires and the optical fiber wires with other electrical components.

[0015] The beneficial effects of the utility model are as follows: ordinary wires and optical fiber wires are integrated together by injection molding, wherein the optical fiber wires are used to realize data transmission requirements, and a communication architecture of an all-optical network is created for application in the whole vehicle network, which can support higher bandwidth (>25Gbps), lower latency, lower cost, longer life, and shorter development cycle; other electrical performance requirements are realized by ordinary wires, and the growing data transmission and electrical performance requirements of new energy vehicles are met; in addition, the detachable connection of two adjacent injection-molded bodies can quickly assemble and fix the wires, which is convenient for improving the wire assembly efficiency; and the injection-molded body has a smaller cross-sectional area than the existing wiring harness structure, and can pass through a narrower area in layout, which can effectively reduce the requirements of the wiring harness for the wiring space in the vehicle, and at the same time, after integrated injection molding, it can provide the prerequisite for realizing the "automatic" production and assembly of the wiring harness.

[0016] The integrated wire is assembled by cooperating with the positioning protrusion structure and the positioning groove structure, thereby overcoming the problem of loose and soft wires and inconvenient assembly, improving the wire assembly efficiency, and further improving the automation rate of wire assembly.

In this embodiment, ordinary wires 2 and optical fiber wires 3 are provided on the injection molded body 1 at the same time, and the ordinary wires 2 and optical fiber wires 3 are combined into a whole to achieve an integrated connection of the wiring harness. Compared with the traditional wiring harness, it has a smaller volume, and the structure of the injection molded body 1 can be designed according to the wiring harness installation environment, so as to meet the installation needs of the wiring harness in an irregular environment, and has strong environmental adaptability.

[0026] In addition, the integrated conductor structure realizes data transmission requirements through optical fiber conductors 3 and realizes other electrical performance requirements through ordinary conductors 2, which can meet the growing data transmission and electrical performance requirements of new energy vehicles; the detachable connection of two adjacent injection-molded bodies 1 can quickly assemble and fix the conductors, thereby improving the efficiency of conductor assembly.

In addition, the cooperation between the positioning protrusion structure 4 and the positioning groove 5 can ensure the stability of the radial relative position between two adjacent injection-molded bodies 1, thereby ensuring the accurate assembly position of the wires.

[0029] Furthermore, a positioning step is provided in the positioning groove structure 5, and the end of the positioning protrusion structure 4 cooperates with the positioning step.
