Abstract
A vehicle lamp includes an optical means whereof the direction of irradiation is change by rotation, a motor, an output shaft for driving the optical means, and a rotation transmitting mechanism for transmitting rotation from the motor to the output shaft. The motor, the output shaft, and the rotation transmitting mechanism are accommodated in the case body, and a revolving shaft of the motor is supported by the case body.
Claims16
A vehicle lamp comprising:
- an optical system whereof the direction of irradiation is changed by rotation;
- a first shaft coupled to the optical system to rotate the optical system;
- a brushless motor;
- and
- a rotation transmitting mechanism coupled to the brushless motor and the first shaft for transmitting rotation from the brushless motor to the first shaft;
- wherein the brushless motor and the rotation transmitting mechanism are accommodated in a case body, and a second shaft of the brushless motor is supported by the case body, the second shaft is preloaded with an urging force, and the urging force exerted on the second shaft is received by a thrust bearing interposed between the second shaft and the case body.
A rotary driving apparatus for rotating an optical means to change the direction of irradiation comprising:
- a brushless motor;
- a first shaft to rotate the optical means;
- and
- a rotation transmitting mechanism coupled to the brushless motor and the first shaft for transmitting rotation from the brushless motor to the first shaft:
- wherein the brushless motor and the rotation transmitting mechanism are accommodated in a case body, and a second shaft of the brushless motor is supported by the case body, the second shaft is preloaded with an urging force, and the urging force exerted on the second shaft is received by a thrust bearing interposed between the second shaft and the case body.
A vehicle lamp comprising:
- an optical system for emitting light;
- a bracket with extending arms to pivotally hold the optical system;
- a first shaft coupled to the optical system through one of the arms to pivot the optical system;
- a contact plate disposed around the first shaft below one of the arms of the bracket, said contact plate being coupled to the first shaft to pivot integrally with the optical system;
- a rotation transmitting mechanism coupled to the first shaft to transmit rotating force to the first shaft;
- a motor coupled to the rotation transmitting mechanism;
- and
- a case to integrally accommodate the motor and the rotation transmitting mechanism, and the case supporting the first shaft.
A vehicle lamp comprising:
- a bracket;
- a lamp body being rotatably and horizontally supported by the bracket;
- an optical means, the direction of irradiation of which is changed by rotation;
- and
- a rotary driving apparatus being supported by the bracket for rotating the optical means, the rotary driving apparatus including:
- a motor;
- a first shaft for driving the optical means, said first shaft being directly connected to the lamp body;
- and
- a rotation transmitting mechanism coupled to the motor and the first shaft for transmitting rotation from the motor to the first shaft,
- wherein the motor, the first shaft, and the rotation mechanism are accommodated in a case body, and a second shaft of the motor is supported by the case body.
