Device for Cleaning an Optical Lens of a Parking Assistance Camera

摘要

A cleaning device for an optical lens of a parking assistance camera includes an inner annular body arranged on the optical lens immovably and so as to partially surround the optical lens radially on the outside, on which inner annular body a receptacle is arranged which is configured annularly and so as to be open towards the object space of the optical lens, and an outer annular body which is arranged coaxially with respect to the inner annular body and at least partially within the receptacle. The outer body is arranged such that it can be moved axially relative to the inner body between an extended cleaning position and a retracted rest position. The outer body is loaded in the direction of the rest position thereof with a restoring force. A fluid chamber is arranged between the inner body and the outer body. The outer ring body is configured such that, when the outer body is situated in the rest position, the fluid chamber is closed with respect to the surroundings of the device, and when the outer body is situated in the cleaning position, the fluid chamber is open with respect to the surroundings of the device such that a fluid introduced into the fluid chamber exits toward the optical lens.
