Intelligent steering system of vehicle lamp

Abstract

The invention relates to an intelligent steering system of a vehicle lamp. The intelligent steering system comprises a smooth spherical supporting seat, a left-and-right steering magnetostriction rod, an up-and-down moving magnetostriction rod and a light emitting diode (LED) lamp set, wherein the left-and-right steering magnetostriction rod is arranged at the lower part of a machine frame of the LED lamp set, and the up-and-down moving magnetostriction rod is arranged at the upper part of the machine frame of the LED lamp set; a spherical bracket is arranged at the lower part of a lamp bowl of the LED lamp set; a ball head is arranged at the lower part of the spherical bracket, and can rotate in the smooth spherical supporting seat; the left-and-right steering magnetostriction rod is driven to extend or shorten by an electromagnetic control device, so that the left-and-right movement of the LED lamp set is realized; and the up-and-down moving magnetostriction rod is driven to extend or shorten by the electromagnetic control device, so that the up-and-down movement of the LED lamp set is realized. According to the intelligent steering system disclosed by the invention, a magnetostriction principle is utilized, and according to the amplifying effect that the freedom degree in the contact movement direction of a spherical surface is high, the "up-and-down" adjustment and the "left-and-right" adjustment of the lamp are realized; besides, the transmission of the magnetostriction rods is sensitive, stable and reliable; and the automatic steering system has a good application prospect in vehicles, and is worth widely popularizing and applying.

Description

technical field [0001] The invention relates to a steering mechanism, and more specifically, the invention relates to an intelligent steering system for adjusting left and right, up and down light beams of automobile headlights using magnetostrictive effect. Background technique [0002] Existing automotive lighting devices mainly include: headlights (low beam, high beam), front fog lamps, etc. In actual use, there are many problems in the traditional headlight system. Since the housing of the lamp is fixed on the car body without rotation function, the irradiation direction of the headlight is consistent with the car body. When the vehicle is turning, especially when the roadside is more dangerous, such as mountain roads or urban roads without street lights at night, because the lights cannot adjust the lighting angle, they usually cannot shine on the inside of the curve, especially when encountering In rainy and foggy weather, the lighting of the curved road ahead is eve...
