Abstract

A dynamically deployable side-view camera mount includes a support body that is movable between a deployed position and a retracted position. The support body in the retracted position allows the camera to at least partially include the angular range captured when the support body is in the deployed position.

First claim

The invention claimed is:

1. A dynamically deployable side-view camera mount, comprising:
a support body having a proximal end that attaches to a motorized vehicle, and a distal end that connects to a side-view camera, wherein
the support body includes two support arms arranged in parallel and interconnected at respective ends via support links attached at pivot points, so the two support arms remain in parallel when in a deployed position and when in a retracted position, and
the support body is mounted such that:
when the support body is in the deployed position, the distal end is positioned away from the motorized vehicle, and an image scene captured by the side-view camera is from a rearward perspective with respect to a forward-moving direction of the motorized vehicle, wherein the image scene-spans an angular range, and
when the support body is in the retracted position, the distal end of the support body is positioned closer to the motorized vehicle than when the support body is in the deployed position, and the side-view camera is positioned to at least partially include the angular range captured by the side-view camera when the support body is in the deployed position.

2. The dynamically deployable side-view camera mount according to claim 1 , further comprising a retraction device comprising a biasing member that, in response to a contact force on at least one of the support body or the side-view camera, is configured to apply a retraction force that urges the support body toward the motorized vehicle to the retracted position.

3. The dynamically deployable side-view camera mount according to claim 1 , wherein an optical axis of the side-view camera when the support body is in the deployed position is not parallel to the optical axis of the side-view camera when the support body is in the retracted position.

4. The dynamically deployable side-view camera mount according to claim 3 , wherein at least a part of the support body is configured to rest within a recessed portion of a body of the motorized vehicle when the support body is in the retracted position.

5. The dynamically deployable side-view camera mount according to claim 1 , wherein the support body includes a plurality of meshed gear plates configured to rotate relative to one another when the support body is moved between the deployed position and the retracted position.

6. The dynamically deployable side-view camera mount according to claim 2 , wherein the support body includes an extendable arm attached to the biasing member that is connected at one end to the support body and to the motorized vehicle at other end so as to exert the retraction force on the support body when the support body is in the retracted position or the deployed position.

7. The dynamically deployable side-view camera mount according to claim 1 , further comprising a first motor configured to respond to a user-initiated control signal to at least one of deploy the support body or retract the support body.

8. The dynamically deployable side-view camera mount according to claim 1 , further comprising a lock configured to keep the support body in the deployed position if a torque generated by a contact force is less than a predetermined torque, but permits the support body to move to the retracted position if the torque is greater than the predetermined torque.

9. The dynamically deployable side-view camera mount according to claim 1 , further comprising a second motor configured to move the side-view camera to a first user-selectable preset position when the support body is in the deployed position, and move the side-view camera to a second user-selectable preset position when the support body is in the retracted position.

10. The dynamically deployable side-view camera mount according to claim 1 , further comprising a cover disposed on the support body on an opposite side of the side-view camera so as to avoid blocking the image scene captured by the side-view camera.

11. The dynamically deployable side-view camera mount according to claim 10 , wherein the cover includes a fin configured to reduce wind loading on the support body and the side-view camera when the motorized vehicle is moving in the forward-moving direction.

12. The dynamically deployable side-view camera mount according to claim 10 , wherein the cover comprises an elastic material.

13. A dynamically deployable side-view camera system, comprising:
a side-view camera; and
a side-view camera mount, comprising:
a support body having a proximal end that attaches to a motorized vehicle, and a distal end that connects to the side-view camera, wherein
the support body includes two support arms arranged in parallel and interconnected at respective ends via support links attached at pivot points, so the two support arms remain in parallel when in a deployed position and when in a retracted position,
the support body is mounted such that:
when the support body is in the deployed position, the distal end is positioned away from the motorized vehicle, and an image scene captured by the side-view camera is from a rearward perspective with respect to a forward-moving direction of the motorized vehicle, wherein the image scene spans an angular range, and
when the support body is in the retracted position, the distal end of the support body is positioned closer to the motorized vehicle than when the support body is in the deployed position, and the side-view camera is positioned to at least partially include the angular range captured by the side-view camera when the support body is in the deployed position.

14. The dynamically deployable side-view camera system according to claim 13 , further comprising a retraction device comprising a biasing member that, in response to a contact force on at least one of the support body or the side-view camera, is configured to apply a retraction force that urges the support body toward the motorized vehicle to the retracted position.

15. The dynamically deployable side-view camera system according to claim 13 , further comprising a light source disposed on the support body or the side-view camera.

16. The dynamically deployable side-view camera system according to claim 15 , wherein the light source is configured to have a different emission state when the support body is in the deployed position than when in the retracted position.

17. The dynamically deployable side-view camera system according to claim 14 , further comprising a motor configured to controllably retract the support body to the retracted position.

18. The dynamically deployable side-view camera system according to claim 17 , further comprising:
a sensor that is supported by the distal end of the support body and oriented to the forward-moving direction; and
a processor configured to identify an object approaching the sensor and actuates the motor to retract the support body to avoid the object striking at least one of the support body or the side-view camera.

19. The dynamically deployable side-view camera system according to claim 18 , wherein:
the sensor is a forward-view camera configured to capture a forward-looking scene; and
the processor is further configured to identify the object in the forward-looking scene approaching the forward-view camera.

20. An apparatus, comprising:
a dynamically deployable side-view camera system including a first side-view camera;
a first support body having a proximal end that attaches to a motorized vehicle, and a distal end that connects to the first side-view camera,
