Abstract

A direction turning device for headlights of an automobile comprises two operation mechanisms, namely, direct operation mechanism and electromagnetic operation mechanisms. For the direct operation mechanism, if an automobile with lefthand drive, the device is connected to the left headlight; if an automobile with righthand drive, the device is connected to the right headlight. Where, the electromagnetic operation mechanism is connected to both left and right headlights and activated synchronously with the steering system. This disclosure has been characterized in the simplized structure and the longevity of use because the electromagnetic mechanism is turned off during daytime driving.

Claims

1. A direction turning system for a left and right headlight of an automobile comprising:

a left and right headlight assembly, each headlight assembly comprising;

a curved cover inside a housing of said headlight;

a movable frame having an upper rotating axis and a lower rotating axis pivotally connected to said curved cover respectively,

a reflector having a light bulb in a center of the reflector and being fixed to said movable frame,

a spool perpendicularly fixed on said lower rotating axis of said movable frame;

a spring underneath said spool and surrounding said lower rotating axis, said spring having an upper end secured at said spool and a lower end secured adjacent an inside of said curved cover;

said turning system further comprising;

a pair of control cables having their first ends connected to said spools of said left and right headlight assemblies and their second ends extending outside said curved covers and around a respective turning point at a bottom of said automobile and then connected to an electromagnetic actuator, said electromagnetic actuator comprising a seat member set at a bottom end of a positioning clamp, having a fitting cavity, a rocking rod hingedly connected to said seat member in said fitting cavity, a moving member slidingly connected to said rocking rod, and a base member connected to said rocking rod and said control cables, and

an oscillating arm being held by said positioning clamp and connected to a steering system of said automobile, wherein said oscillating arm sways said movable frame of said headlights toward a direction of a turn of said automobile.

2. A direction turning device according to claim 1, wherein said fitting cavity of said seat member is tapered shaped.

3. A direction turning device according claims 1 or 2 further has an electrical coil inside said seat member above said fitting cavity.

4. A direction turning device according to claim 1, wherein said movable member is a tapered shaped magnet having a central bore therein.

5. A direction turning device according to claim 1, said electromagnetic actuator is electrically connected with said headlights.
