Camera arm of a camera-based mirror substitute system for a motor vehicle
A camera arm of a camera system for a vehicle comprises a first structural element connecting the camera arm to the vehicle and a second structural element comprises at least one camera. A fastening for the at least one camera offers protection against external damaging influences on the fastening, the camera arm, and on all elements, devices, and modules arranged thereon. The camera arm comprises a variable-volume fluid vessel, connecting the first and the second structural element to one another. At least one restoring element connects the first and the second structural element to one another. The restoring element exerts a force on the second structural element in the direction of the first structural element. The force is varied as a result of the amount of fluid in the fluid vessel, such that the second structural element is moved relative to the first structural element by the varying force.
1. A camera arm of a camera-based mirror substitute system for a motor vehicle comprising:
a first structural element connecting the camera arm to the motor vehicle;
a second structural element, which comprises at least one camera;
a variable-volume fluid vessel, which connects the first structural element and the second structural element to one another directly or by at least one intermediary elements;
at least one restoring element, which connects the first structural element and the second structural element to one another directly or by way of at least one intermediary elements;
wherein the at least one restoring element exerts a force on the second structural element in the direction of the first structural element, and wherein the force exerted by the at least one restoring element is varied as a result of the amount of fluid located in the fluid vessel, such that the second structural element is moved relative to the first structural element by the varying force; and
wherein the first structural element further comprises at least one camera and the second structural element further comprises at least one camera.
2. The camera arm as claimed in claim 1 , wherein the fluid vessel further comprises a rolling bellows or a device acting as a rolling bellows.
3. The camera arm as claimed in claim 2 , wherein the rolling bellows is composed of an elastomer material.
4. The camera arm as claimed in claim 1 wherein the at least one restoring element is a spiral spring.
5. The camera arm as claimed in claim 1 , wherein the fluid vessel is double-walled, and wherein the fluid is located between the double-walls, and wherein the double-walls are shaped such that the fluid assumes the shape of a cylinder jacket.
6. The camera arm as claimed in claim 1 , wherein at least two cameras cover at least two different image areas.
