Description

Technical Field

[0001] The utility model relates to the technical field of automobile electronic control, in particular to a flash unit assembly. Background Art

[0002] One of the core functions of the flash unit assembly is controlling the vehicle's exterior lighting, including headlights, taillights, and turn signals. Through a built-in control module, it automatically adjusts the brightness and on / off status of the lights based on ambient light conditions. For example, at night or in low light, the system automatically activates the low beams. When the vehicle turns, the turn signals flash to alert other road users. This intelligent control not only improves driving safety but also reduces the driver's operational burden.

[0003] Publication No. CN201158339Y discloses a flash unit assembly designed to overcome the shortcomings of existing flash units with trailer detection circuits, complex control circuits, and excessive cost, simplifying the circuit structure, improving reliability, and reducing costs. The assembly is characterized by comprising a flash control chip, five relays, nine transistors, and their accessories. Two sampling circuits, Rs1 and Rs2, are connected in parallel via relay contacts. When a trailer is attached, resistors Rs1 and Rs2 jointly provide load current, improving load capacity. When no trailer is attached, the transistors control the relay's operating state. Sampling resistor Rs1 is connected to the relay's static contacts, providing power for three 21W (63W) bulbs on each side. When a trailer is attached, the relay connects sampling resistor Rs2 in parallel with sampling resistor Rs1. The relay contacts connect the left and right trailer lights, connecting the left and right vehicle and trailer lights in parallel and ensuring synchronous flashing. However, this circuit design is complex and production costs are high, so improvements have been made to this circuit. Summary of the Invention
