The invention discloses a universal headlamp adjusting device and system, wherein, the device comprises a first power input terminal, a second power input terminal, an adjusting signal output terminal, an n-gear selection switch and n+1 resistors; Wherein n is a natural number and n >= 2, the first power supply input terminal and the second power supply input terminal are respectively used for connecting the power supply source electrodes, and the adjustment signal output terminal is used for outputting the adjustment signal to the headlamp motor; (n+1) resistor are serially connected betweenthat first power supply input terminal and the second power supply input terminal, and are symmetrically arranged between the first power supply input terminal and the second power supply input terminal according to the resistor resistance value; The n-gear selection switch comprises a common terminal and n selection terminals, wherein an adjustment signal output terminal is connected with the common terminal, and one of the selection terminals is connected between every two adjacent resistors. The invention realizes the wiring mode of exchanging the positive and negative poles of the power supply, that is, the headlamp adjusting motor can be adapted to different layout positions.
Description
technical field [0001] The invention relates to the field of vehicle lighting control, in particular to a general-purpose headlight adjustment device and system. Background technique [0002] The function of the headlight adjustment switch is to adjust the length of the motor output shaft inside the headlight through the headlight adjustment switch to adjust the irradiation angle of the headlight after turning on the headlight, thereby adjusting the irradiation height of the headlight. [0003] However, due to various reasons, the position of the motor inside the headlight is sometimes at the top, so the lowest gear output voltage ratio of the headlight adjustment switch is required to be the largest (for example, set to 0 gear to output 80% voltage), and the highest gear output voltage ratio is the smallest. (For example, it is set to output 20% voltage at gear 6); but when the motor is arranged at the bottom, it needs to be controlled with inverse logic: the voltage ratio ...
