Abstract
An automatic turning headlight structure includes a headlight structure, a running gear and a server, the headlight structure being mounted through a rotatable main shaft at the front side of the car. The server is placed inside the headlight structure, and connected by a shaft with the main shaft. The server receives a signal to turn and to transmit a force to the shaft to drive the main shaft to make the headlight turn left or right, following the movement of the steering wheel.
Claims8
An automatic headlight turning structure, comprising:
- a headlight support structure defining an interior space for receiving a headlight, the support structure having a main shaft adapted for being rotatably mounted at a front end of an automobile;
- a server mounted in the interior space of the support structure, a secondary shaft coupled between the main shaft and the server, and means, including first and second variable resistors, for moving the secondary shaft to rotate the support structure and the headlight therewith from a straight-ahead lighting position, in a first light-turning direction with a change in the resistance of the first variable resistor, and for moving the secondary shaft to rotate the support structure and the headlight therewith from the straight-ahead lighting position in a second light-turning direction opposite the first light-turning direction with a change in the resistance of the second variable resistor;
- a compact gear wheel speed changing structure, coupled to the steering wheel of the automobile and the first variable resistor, so as to control the resistance of the first variable resistor with rotation of the steering wheel in a first steering direction from a straight-ahead steering position and so as to control the resistance of the second variable resistor with rotation of the steering wheel in a second steering direction opposite to the first steering direction, from the straight-ahead steering position, such that the headlight support structure rotates by an amount and in a direction corresponding to the rotation of the steering wheel;
- and
- means for altering responsiveness of the variable resistors to the rotation of the steering wheel when the automobile is backing up, so that the compact gear wheel speed changing structure controls the resistance of the second variable resistor with rotation of the steering wheel in the first steering direction from the straight-ahead steering position and controls the resistance of the first variable resistor with rotation of the steering wheel in the second steering direction from the straight-ahead steering position, so that the headlight support structure rotates with rotation of the steering wheel in an opposite direction relative to that when the automobile is not backing up.
