Abstract
An exterior mirror assembly with an actuator is provided. The actuator comprises: a gear element, a driving unit and a limiting element. The driving unit is configured to impart a rotation of the gear element. The limiting element is adjacent to a circumference of the gear element. The gear element has a teeth portion with a first end and a second end and the teeth portion extends along the circumference of the gear element. The limiting element leans against the first end or the second end of the teeth portion when the driving unit drives the gear element to rotate by an angle.
Claims13
An exterior rearview mirror assembly for a vehicle, comprising
- a mounting portion mountable at a side of the vehicle;
- a mirror head portion adjustably mounted at said mounting portion;
- a reflective element at said mirror head portion;
- and
- an actuator operable to impart pivotal movement of said mirror head portion relative to said mounting portion;
- wherein the actuator comprises:
- a gear element having a teeth portion and a missing teeth region,
- a driving unit configured to drive the gear element to pivot said mirror head portion relative to said mounting portion;
- and
- a limiting element located to corresponding to the missing teeth region and configured to engage with the teeth portion in order to prevent the gear element from causing any pivoting movement between the mirror head portion and the mounting portion,
- wherein the actuator comprises an axle portion configured to receive the gear element, and wherein the limiting element is disposed at the axle portion, and wherein the axle portion has an inner wall and an outer wall and the gear element is disposed in a groove between the inner wall and the outer wall, and wherein the limiting element is disposed at the outer wall of the axle portion.
An actuator for an exterior rearview mirror assembly for a vehicle, comprising:
- a gear element;
- a driving unit configured to impart a rotation of the gear element;
- and
- a limiting element adjacent to a circumference of the gear element;
- wherein the gear element has a teeth portion with a first end and a second end and the teeth portion extends along the circumference of the gear element;
- wherein the limiting element leans against the first end or the second end of the teeth portion when the driving unit drives the gear element to rotate by an angle,
- wherein the limiting element is disposed between the first end and the second end of the teeth portion, and wherein the limiting element has a wing portion extending along the circumference of the gear element and configured to come into contact with the first end or the second end of the teeth portion when the driving unit drives the gear element to rotate by the angle.
