Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts, and in particular to a vehicle-mounted integrated signal harness connection system. Background Technology

[0002] Traditional in-vehicle infotainment system wiring harnesses typically use multiple harnesses, several meters long, to connect various devices and circuit boards. These harnesses usually consist of multiple cables and wires, connected according to the functional requirements of the devices and circuit boards. These cables transmit various signals and power, supporting data and power transmission between multiple devices such as display modules, audio systems, navigation systems, and central control units. However, existing in-vehicle infotainment system signal harness connection methods have the following technical drawbacks:

[0003] 1. Lengthy and complex wiring: Traditional wiring harness solutions require multiple long cables, which not only increases the overall complexity of the vehicle-mounted integrated system but also increases the difficulty of installation, maintenance, and debugging. Excessively long wiring can easily lead to signal attenuation, noise interference, and other problems, affecting the stability and performance of the system.

[0004] 2. Large space occupation and inconvenient installation: Due to the complexity and length of traditional wiring harnesses, they usually require a certain amount of space in the vehicle, which increases the difficulty of installing the vehicle-mounted integrated unit. Especially in the limited space of the vehicle, the wiring method of the wiring harness often makes the system assembly and subsequent maintenance more complicated.

[0005] 3. High cost and difficulty in quality control: Traditional wiring harness connections require a large number of cables and connectors, which not only increases production and assembly costs but also makes quality control more difficult. Unstable wiring harness quality can lead to problems such as short circuits, poor contact, and overheating, thereby affecting the reliability and lifespan of the vehicle-mounted integrated unit.

[0006] 4. Electromagnetic Interference (EMI) and Signal Noise: The electromagnetic compatibility of each wire in a traditional wire harness often fails to meet the requirements of high-frequency signal transmission, which may lead to signal attenuation and electromagnetic interference, especially affecting the transmission of video signals, audio signals and data buses. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vehicle-mounted integrated signal harness connection system that occupies little space, is easy to maintain, and is resistant to interference.

[0008] The technical solution adopted by this utility model is as follows: This utility model includes a motherboard, a first electronic module, and a second electronic module. The motherboard is connected to an expansion board via a motherboard connection harness. The expansion board is connected to a motherboard power harness and a motherboard signal harness. A power harness is detachably connected to the motherboard power harness, and a signal harness is detachably connected to the motherboard signal harness. The power harness has multiple first connection ports, including turn and reverse signal wiring ports, a host power wiring port, an ACC signal wiring port, and multiple camera wiring ports. The first electronic module includes a first camera, a second camera, a driver monitoring camera, and a forward-looking AI, all detachably connected to camera extension cables. The camera includes multiple camera extension cables that are detachably connected to multiple camera wiring ports. The signal harness has multiple second connection ports. The second electronic module includes a right radar extension harness, a front radar extension harness, a front-view AI camera extension harness, an OBD extension harness, a function switch extension harness, and a brake actuator extension harness that are detachably connected to multiple second connection ports. The right radar extension harness and the front radar extension harness are detachably connected to the right radar and the front radar, respectively. The front-view AI camera extension harness is detachably connected to the front-view AI camera. The function switch extension harness and the brake actuator extension harness are detachably connected to the in-vehicle control switch and the brake actuator, respectively.

[0009] Furthermore, the outer layers of the motherboard connection harness, the motherboard power harness, the motherboard signal harness, the power harness, the signal harness, the camera extension cable, the right radar extension harness, the front radar extension harness, the front-view AI camera extension harness, the OBD extension harness, the function switch extension harness, and the brake actuator extension harness are all covered with a shielding layer.

[0010] Furthermore, the connection ends of the motherboard power harness, the motherboard signal harness, the power harness, the signal harness, and the camera extension cable are all provided with connector interfaces.

[0011] Furthermore, the front radar extension harness is detachably connected to the front radar.

[0012] Furthermore, it also includes a host housing, in which the motherboard and the expansion board are located.

[0014] Furthermore, the motherboard is equipped with a SIM card and a TF memory card, and is connected to an alarm, GPS, and 4G antenna.

[0015] The beneficial effects of this utility model are:

[0016] In contrast to the shortcomings of existing technologies, this invention, by splitting a single long wire harness into multiple detachable short wire harnesses, not only significantly reduces the length and complexity of traditional wire harnesses but also improves the flexibility of system wiring. Each short segment can be adjusted according to different needs, avoiding the layout limitations caused by excessively long wire harnesses, optimizing the entire installation process, reducing the failure rate, and improving maintenance efficiency. Moreover, since the multiple short wire harnesses are detachably connected, it is easy to replace damaged parts individually without replacing the entire wire harness. The independence of each segment simplifies quality management, especially during the production and maintenance phases. Any problems in system operation can be accurately located to individual short wire harnesses, thereby reducing maintenance costs and resource waste, while improving stability and reliability in long-term use. Furthermore, by adding a shielding layer to the outer layer of each wire harness segment, the shielding layer can effectively isolate interference from external electromagnetic sources while ensuring clear signal transmission within the wire harness. This structural optimization significantly improves electromagnetic compatibility (EMI), reduces signal distortion, and enhances the overall system stability, giving this invention the advantages of small footprint, easy maintenance, and anti-interference capabilities.

[0027] In contrast to the shortcomings of existing technologies, this invention, by breaking down a single long wire harness into multiple detachable short wire harnesses, not only significantly reduces the length and complexity of traditional wire harnesses but also improves the flexibility of system wiring.

This shielding layer effectively isolates interference from external electromagnetic sources while ensuring clear signal transmission within the harness. This structural optimization significantly improves electromagnetic compatibility (EMI), reduces signal distortion, and enhances the overall system stability.

[0029] In some embodiments, the connection ends of the motherboard power harness 5, the motherboard signal harness 6, the power harness 7, the signal harness 8, and the camera extension cable 13 are all provided with connector interfaces 31.
