Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a structure for an intelligent driving light for automobiles. Background Technology

[0002] With the development of intelligent driving technology in the automotive industry, the era of intelligent driving has arrived. When a vehicle activates intelligent driving mode, a signal is needed to alert surrounding vehicles to the intelligent driving mode. To this end, intelligent driving mode indicator lights have emerged. The intelligent driving mode is indicated by the ADS intelligent driving blue light, which automatically illuminates after the ADS intelligent driving blue light activation switch is touched. However, while integrating intelligent driving lights into newly manufactured or designed turn signal assemblies is relatively easy, for vehicles already on the market, the size limitations of the turn signal structure make it difficult to integrate intelligent driving lights into the existing turn signal structure. Directly replacing the turn signal assembly is costly, causing inconvenience for vehicles already on the market and reducing the user experience. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent driving light structure for automobiles, so as to solve the problem that it is difficult to integrate or add intelligent driving lights to existing automobile turn signals.

[0005] As an optimization, the yellow LED and the blue LED are each a single LED, integrated on the same LED driver chip or on separate LED driver chips. The LED driver chip is mounted on the side of the PCB circuit board facing the light guide strip. The yellow LED and the blue LED are connected to the first circuit component and the second circuit component respectively through their respective contacts.

The yellow and blue LEDs are integrated on the same LED driver chip, or the yellow and blue LEDs are each integrated on an independent LED driver chip. The yellow and blue LEDs are electrically connected to the first circuit component and the second circuit component through their respective contacts.

[0008] Compared with the prior art, this utility model has the following advantages: by integrating yellow and blue LED beads on the PCB circuit board of the turn signal, the coexistence of yellow turn signals and blue intelligent driving lights is achieved. The additional electronic components required for the intelligent driving lights are solved by using a double-sided PCB circuit board. Thus, the integration or addition of intelligent driving lights is achieved without changing the original turn signal structure and PCB circuit board size, and with minimal cost changes.

[0013] Example: See Figures 1 to 2A vehicle intelligent driving light structure includes a turn signal assembly, which includes a lamp holder 5 and a lamp cover 6. The lamp holder 5 has a mounting groove 1 on the side near the lamp cover 6. The lamp cover 6 has a light guide strip 2. A PCB circuit board 3 is vertically mounted in the mounting groove 1 to reduce space occupation. An LED lamp bead assembly 4 is provided on the PCB circuit board 3. When the lamp cover 6 is fastened to the lamp holder 5, the LED lamp bead assembly 4 faces the light guide strip 2. The LED lamp bead assembly 4 includes at least one blue LED bead and one yellow LED bead. The blue LED bead is electrically connected to the vehicle power supply through a first circuit assembly, and the yellow LED bead is electrically connected to the vehicle power supply through a second circuit assembly. The electronic components used in the first and second circuit assemblies are distributed on both sides of the PCB circuit board 3. Of course, if the number of electronic components used is small and heat dissipation is considered, the electronic components can also be distributed on one side and a heat sink can be installed on the other side for heat dissipation. For a double-sided layout, full copper plating heat dissipation is adopted. Specifically, this embodiment uses a dual-channel transistor constant current circuit. One channel is connected to the yellow LED bead for the turn signal indicator (i.e., the first circuit component), and the other channel is connected to the blue LED bead for the intelligent driving indicator (i.e., the second circuit component). The circuit component is a conventional circuit structure. As needed, a TVS + capacitor filter + LED indicator can be added to provide power management, and / or a diode + resistor for level matching or signal isolation, and / or a TVS + resistor to prevent overvoltage or electrostatic discharge. These details will not be elaborated here.

[0014] Specifically, in this embodiment, each of the yellow and blue LED beads is a single bead, integrated onto the same LED driver chip or separately onto independent LED driver chips. The LED driver chip is mounted on the side of the PCB circuit board 3 facing the light guide strip 2. The yellow and blue LED beads are electrically connected to the first and second circuit components respectively through their respective contacts. The yellow and blue LED beads are arranged horizontally or vertically on the LED driver chip, depending on the light distribution requirements of the light guide strip 2. The LED driver chip is a mature existing product; in this embodiment, the BC847C,215SOT-23 chip or the BCP5616TA SOT-223-4 chip from JCET Group is used.

[0015] In another embodiment, there is one yellow LED and multiple blue LEDs evenly distributed around the yellow LED; or there is one blue LED and multiple yellow LEDs evenly distributed around the blue LED. The yellow and blue LEDs are integrated on the same LED driver chip, or the yellow and blue LEDs are each integrated on a separate LED driver chip. The yellow and blue LEDs are connected to the first circuit component and the second circuit component respectively through their respective contacts.

[0016] In summary, this utility model 1. The structure of the turn signal housing remains unchanged, and the PCB board dimensions are not altered. The ADS blue intelligent driving light is integrated onto the turn signal PCB board. The blue ADS intelligent driving light and the yellow turn signal can use independent yellow and blue LEDs; alternatively, a single LED with integrated yellow and blue light can be used (this type of LED is existing technology). The LED arrangement can be horizontal or vertical. Whether using independent yellow and blue LEDs or integrated yellow and blue LEDs, the arrangement and number of LEDs can be determined based on the turn signal housing shape and the turn signal's light distribution analysis. One or more LEDs can be used.

[0017] 2. Without changing the external dimensions of the circuit board, the design of the circuit board is adjusted to achieve the coexistence of blue and yellow light. The heat dissipation and heat resistance requirements of the circuit board are met through the heat dissipation technology of the PCB. At the same time, the reverse protection, voltage reduction surge protection, and electrostatic high voltage protection functions are achieved through capacitors, resistors and packaging technology.

[0018] Therefore, this utility model achieves the coexistence of yellow turn signals and blue intelligent driving lights by integrating yellow and blue LED beads on the PCB circuit board of the turn signal. The additional electronic components required for the intelligent driving lights are solved by using a double-sided PCB circuit board. Thus, the integration or addition of intelligent driving lights is achieved without changing the original turn signal structure and PCB circuit board size, and with minimal cost changes. This allows for a low-cost upgrade of intelligent driving turn signals for existing cars on the market, improving the user experience.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and not to limit the technical solutions. Those skilled in the art should understand that any modifications or equivalent substitutions to the technical solutions of this utility model that do not depart from the spirit and scope of this technical solution should be covered within the scope of the claims of this utility model.
