Problems solved by technology

[0006] This prior art solution is ineffective against strongly attached foreign objects, such as: dried mud or insects, because the impact energy of the impinging cleaning fluid is wasted on surfaces other than the one to be cleaned

Embodiment Construction

[0043] figure 1An optical sensor 1 is shown with a cleaning device 10 suitable for mounting to an exterior surface of a vehicle. The cleaning device 10 is preferably made of plastic material and is configured to clean the optical surface 2 of the optical sensor 1 by expelling a cleaning liquid onto the optical surface 2 .

[0044] The optical sensor housing 3 and the housing 11 of the cleaning device 10 are mounted together such that the optical surface 2 is mounted at the opening 12 of the housing 11 of the cleaning device.

[0045] This opening 12 is surrounded by a protrusion 20 provided in the housing 11 , which defines an inner wall 21 surrounding the opening 12 . At least one fluid discharge opening 22 is provided in the housing 11 , preferably in the inner wall 21 of the protrusion 20 , and is arranged to discharge cleaning fluid onto the optical surface 2 in the operating state of the cleaning device 10 . In this embodiment, four fluid outlets 22 are provided in the ...

Abstract

A first aspect of the invention refers to a cleaning device (10) for cleaning a vehicle-mounted optic surface (2), comprising a housing (11), the housing (11) comprising an opening (12) adapted to fit an optic surface (2), a fluid inlet (13) arranged to take in washer fluid, an at least one fluid discharge port (22) arranged to discharge washer fluid onto the optic surface (2), a first passage (23) in fluidic communication with the fluid inlet (13) and the at least one fluid discharge port (22) so as to guide the washer fluid from the fluid inlet (13) towards the at least one fluid discharge port (22) and a protruding part (20) that substantially surrounds the opening (12) so as to define an inner wall (21). The invention also refers to a cleaning system and to a vehicle-mounted sensor (1) comprising an optic surface (2) and a cleaning device (10).

Description

technical field [0001] The invention relates to a cleaning device and a cleaning system for a vehicle-mounted optical surface and a vehicle-mounted optical sensor with the cleaning device. Background technique [0002] Currently, motor vehicles are often equipped with optical sensors to assist drivers in various traffic situations, such as, but not limited to, parking assistance, object detection in blind spots, lane departure, traffic signal recognition, or rearview mirror replacement. [0003] Typically, these optical sensors are mounted on the exterior surface of the vehicle so that the optical surface, eg a lens surface or a cover window provided in front of said lens surface, is exposed to foreign matter such as insects, raindrops, mud or dust. Therefore, it is necessary to remove foreign matter attached to the optical surface of the in-vehicle optical sensor. [0004] It is known in the art to provide a cleaning device for cleaning an optical surface of an optical sen...
