Description

Matching device for vehicle daytime running lights

The present invention relates to a lighting device for a car, and more particularly to a docking device for a daytime running light of a vehicle that can be installed by a user.

In recent years, the number of cars in the world has grown by an alarming number, which has made traffic safety problems more and more serious. For reasons of driving safety, only Canada and some Nordic countries have required vehicles to turn on the headlights during daytime driving. Lighting the headlights can cause attention and alertness to the incoming vehicles. It has been found by statistics that not only the number of accidents has been reduced, but also the death rate of the accidents has been reduced. In 2008, the EU also requested new cars for all cars and minivans since 2011. The model must be equipped with Daytime Running Light (DRL).

It is known that the daytime running light installed by the original automobile manufacturer in a new type of vehicle (generally called the daytime running light of the original factory) is automatically turned on when the automobile engine is started, when the driver turns on the headlight of the vehicle or When the general low beam is used, the daytime running light will be automatically extinguished. The driver can't interfere with the daytime running or turning off without control. Make sure that the vehicle is running after the engine is started or during the running, daytime running lights or headlights. It can be kept in a lit state to maintain driving safety. For older vehicles that have not yet installed daytime running lights in the early days, the daytime running lights and their controls used in vehicles have been sold on the market, and the driver or vehicle owner can purchase and install them on the vehicle. In order to distinguish it from the original daytime running lights, the following will be installed by the driver. The lamp and its control device are called "daytime running light components". Based on the characteristics that the daytime running lights should be automatically turned on or off, the general "daytime running light assembly" control device will still detect the operation information of the vehicle. The operation information of the vehicle automatically controls the daytime running light to be on or off.

A known "daytime running light assembly" that can be installed by the driver, wherein the control device is connected to the vehicle's on-board diagnostic system or the traveling computer through the OBD socket of the On Board Diagnostics (OBD). In order to obtain the operation signal of the vehicle, and further electrically connect with the power system of the vehicle through a power controller to obtain the power provided by the vehicle power system, the control device automatically controls the daytime running light according to the operation information of the current vehicle. Or the function of extinguishing. This known "daytime running light assembly" must be connected to the OBD socket and the power system of the vehicle separately during the installation process. Because it involves the power system of the car, it can be easily accomplished by a non-general driver or user. It is necessary to entrust a professional who is familiar with the structure of the automobile and has the knowledge of the automobile. The construction work is quite cumbersome and inconvenient, and the construction of the original vehicle must be damaged, and the vehicle manufacturer's warranty responsibility is not recognized; on the other hand, this is known. The power supply controller of the "daytime running light module" must convert the power provided by the vehicle's power system into a power source suitable for the daytime running light, and an appropriate power conversion circuit needs to be provided.
