Abstract

A mirror assembly for a vehicle is disclosed. The mirror assembly comprises a support bracket, a glass element operably coupled with the support bracket, and an actuator assembly. The actuator assembly is in connection with the support bracket, wherein the actuator assembly is adjustable to tilt the glass element to a first position and to a second position. A damper is in engagement with the actuator assembly and the support bracket. The damper controls a movement of the actuator assembly corresponding to the movement of the glass element from the first position to the second position. The mirror assembly further comprises a sensor configured to detect a position of the actuator assembly.

Claims

1. An actuator assembly for a vehicle mirror comprising:

a toggle switch configured to rotate about a pivotal axis;

a damper in connection with the toggle switch and configured to control the rotation about the pivotal axis; and

a support bracket in connection with the vehicle mirror and forming a pivotal interface with the damper and the toggle switch, wherein the pivotal interface is configured to toggle an orientation of the vehicle mirror between a first position and a second position, wherein the first position corresponds to an on-axis position wherein the mirror is oriented by the support bracket to direct a rearward directed reflection to an operator of the vehicle.

2. The actuator assembly according to claim 1, wherein the second position corresponds to an off-axis position wherein the mirror is oriented by the support bracket to direct a rearward directed reflection away from the operator of the vehicle.

3. The actuator assembly according to claim 1, wherein the damper is a rotational damper configured to engage a trough formed by the support bracket.

4. The actuator assembly according to claim 3, wherein the rotational damper comprises an engaging surface forming the pivotal interface in assembly with the trough of the support bracket.

5. The actuator assembly according to claim 4, wherein the damper comprises a locating feature configured to engage a receiving aperture formed in the support bracket.

6. The actuator assembly according to claim 5, wherein the locating feature is configured to retain an orientation of the engaging surface relative to the trough.

7. The actuator assembly according to claim 6, wherein the damper comprises a rotating portion in connection with the toggle switch.

8. The actuator assembly according to claim 7, wherein the rotating portion applies a damping force to the toggle switch through the engaging surface in response to a rotation of the pivotal interface from the first position to the second position.

9. A mirror assembly for a vehicle, comprising:

a support bracket;

a glass element operably coupled with the support bracket;

an actuator assembly in connection with the support bracket, wherein the actuator assembly is adjustable to tilt the glass element between a first position and a second position;

a damper in engagement with the actuator assembly and the support bracket, wherein the damper controls a movement of the actuator assembly between the first position and the second position; and

a sensor configured to detect a position of the actuator assembly.

10. The mirror assembly according to claim 9, wherein the sensor forms a channel configured to receive a protrusion of the actuator assembly.

11. The mirror assembly according to claim 10, wherein the protrusion extends outward from the actuator assembly and into the channel in the first position.

12. The mirror assembly according to claim 11, wherein the protrusion is withdrawn from the channel in the second position.

13. The mirror assembly according to claim 9, wherein the sensor corresponds to an optical sensor.

14. The mirror assembly according to claim 9, further comprising a control circuit in communication with the sensor, wherein the control circuit is configured to activate a display in response to the actuator assembly located in the second position.

15. The mirror assembly according to claim 14, wherein the control circuit is further configured to deactivate the display in response to the actuator assembly located in the first position.

16. A mirror assembly for a vehicle, comprising:

a support bracket;

a display screen comprising a display surface configured to display image data;

a glass element disposed on the display surface and operably coupled with the support bracket;

an actuator assembly in connection with the support bracket, wherein the actuator assembly is adjustable to tilt the glass element between a first position and a second position;

a damper in engagement with the actuator assembly and the support bracket, wherein the damper controls a movement of the actuator assembly between the first position and the second position; and

a sensor configured to detect a position of the actuator assembly.

17. The mirror assembly according to claim 16, wherein the actuator assembly comprises a protrusion, the protrusion extending outward from the actuator assembly and into a detection region of the sensor in the first position.

18. The mirror assembly according to claim 17, wherein the protrusion is withdrawn from the detection region in the second position.

19. The mirror assembly according to claim 17, further comprising a control circuit in communication with the sensor, wherein the control circuit is configured to deactivate the display screen in response to the detection of the protrusion in the detection region.
