High and low-beam integrated lamp switching device of automobile and high and low-beam switching method

Abstract

The invention discloses a high and low-beam integrated lamp switching device (100) of an automobile and a high and low-beam switching method. The high and low-beam integrated lamp switching device (100) of the automobile comprises a high and low-beam integrated lamp (20), a gradual switching structure (40), a lamplight collector (50) and a processor (60); the gradual switching structure (40) comprises a gradual switching shading plate (41) and a stepper motor (42), the gradual switching shading plate (41) has an initial position and a highest position, and the stepper motor (42) drives the gradual switching shading plate (41) to move between the initial position and the highest position; the lamplight collector (50) is used for transmitting collected lamplight signals of an oncoming automobile to the processor (60); the processor (60) computes the distance from the oncoming automobile to the automobile according to the collected lamplight signals, and determines a target position of the gradual switching shading plate (41) according to a computation result, and the stepper motor (42) drives the gradual switching shading plate (41) under the control of the processor (60), so that the gradual switching shading plate (41) can reach the target position.

Description

technical field [0001] The present invention relates to a vehicle lamp, and in particular to a switching device and a method for switching high and low beams of an automobile integrated lamp for high and low beams. Background technique [0002] Generally, the lights of vehicles need to have the function of switching high beam and low beam. There are two methods commonly used in the industry. One is to use separate designs for high beam and low beam, that is, to provide two sets of lights, one The car light provides low beam light, and another set of car lights provides high beam light, but this design will undoubtedly increase the cost and cause difficulties in space layout; Switch between high beam and low beam. [0003] figure 1 and figure 2 That is, a far and near beam integrated lamp is disclosed, which includes a lamp holder 11 , a luminous body 12 , a light-transmitting cover 13 , a light-shielding plate 15 , and a solenoid valve 16 . The illuminant 12 is disposed...
