Abstract
An illumination axis adjusting apparatus includes a stepping motor integrally having in turn an automatic angle adjusting structure for automatically adjusting the angle of the illumination axis of an automotive headlamp by driving the motor and a manual angle adjusting structure for manually adjusting the angle of the illumination axis of the headlamp.
Claims16
An illumination axis adjusting apparatus for automotive headlamps comprising:
- an automatic illumination axis adjustor having an automatic angle adjusting structure, comprising a motor with a rotor, for automatically adjusting the angle of the illumination axis of an automotive headlamp and a manual angle adjusting structure for manually adjusting the angle of the illumination axis of said automotive headlamp, said automatic angle adjusting structure and said manual angle adjusting structure being integrated together, and connected to an output shaft that effects movement of a portion of the headlamp, wherein said rotor extends along a longitudinal axis that is parallel to a longitudinal axis of said output shaft;
- and
- a manual angle adjustor for manually adjusting the angle of the illumination axis of said automotive headlamp, said automatic illumination axis adjustor being adapted for adjusting the angle of said illumination axis in vertical directions, and said manual angle adjustor being adapted for adjusting the angle of said illumination axis in horizontal directions.
An illumination axis adjusting apparatus for automotive headlamps comprising:
- a first automatic illumination axis adjustor having a first automatic angle adjusting structure for automatically adjusting the angle of the illumination axis of an automotive headlamp in horizontal directions and a first manual angle adjusting structure for manually adjusting the angle of the illumination axis of said automotive headlamp, said first automatic angle adjusting structure and said first manual angle adjusting structure being integrated together;
- and
- a second automatic illumination axis adjustor having a second automatic angle adjusting structure for automatically adjusting the angle of the illumination axis of said automotive headlamp in vertical directions and a second manual angle adjusting structure for manually adjusting the angle of the illumination axis of said automotive headlamp, said second automatic angle adjusting structure and said second manual angle adjusting structure being integrated together.
An illumination axis adjusting apparatus for automotive headlamps, comprising:
- a stepping motor, said stepping motor comprising a rotor;
- an automatic angle adjusting structure, for automatically adjusting the angle of the illumination axis of an automotive headlamp, connected to said motor;
- and
- a manual angle adjusting structure for manually adjusting the angle of the illumination axis of said automotive headlamp;
- wherein said automatic angle adjusting structure and said manual angle adjusting structure are integrated together, and are connected to an output shaft that effects movement of a portion of the headlamp, and
- further wherein said rotor extends along a longitudinal axis that is parallel to a longitudinal axis of said output shaft.
