A wiper device for a small and curved surface such as a spherical surface of an optical element includes at least one elongate wiper element with two ends, two drive units to which the ends of the wiper element are attached so that the wiper element can be moved on the surface of the optical element using the two drive units, and at least one contacting means for bringing the wiper element into contact with a surface of the optical element, the contacting means shapes the wiper element around at least that part of the surface which is exposed to the environment due to an opening provided by the housing and is to be cleaned.

A vehicle camera protection and cleaning system is disclosed in which at least one wiper is positioned on an underside surface of a camera cover to clean a lens of a vehicle camera. In one embodiment, the system includes an inner ring fixedly attached to an underside surface of the cover, and a plurality of aperture members pivotally connected to the inner ring on one end and pivotally connected on another end to an outer gear that is movable relative to the inner gear, where at least one of the plurality of aperture members comprises a wiper configured to clean a lens of the camera when the aperture members are moved over the lens. In other embodiments, the wiper may be positioned on an underside surface of a cover of the camera that either rotates in a circular manner or translates over the lens of the camera.

A camera cleaning system for a vehicle includes a camera including a lens cover and a motor. A cleaning assembly includes an arm including a cleaning material. The motor selectively adjusts a position of the arm and the cleaning material relative to the lens cover of the camera. The motor selectively adjusts a position of the arm and the cleaning material relative to vehicle from a first position to a second position. The camera selectively generates video signals when the camera is in the first position. The cleaning assembly is in contact with the lens cover when the camera is in the second position

The present disclosure relates to vehicle technology, and more particularly, to an unmanned vehicle and its sensor device and cleaning mechanism. The cleaning mechanism includes: a housing, a cleaning element, a driving component transmissively connected to the cleaning element and a control unit installed within a receiving cavity. The housing has a light transmissive element provided on a side surface thereof. The cleaning element is pivotable about one end thereof and mounted to the housing. The cleaning element, when pivoting, frictionally interacts with a surface of the light transmissive element that is away from the receiving cavity to clean the light transmissive element. The control unit is communicatively connected to the driving component for controlling the driving component.

The subject disclosure relates to features that facilitate the automatic cleaning of optical sensors and in particular Light Detection and Ranging (LiDAR) sensors used in autonomous vehicle deployments. In some aspects, the disclosed technology includes a sensor cleaning apparatus having a housing, wherein the housing is configured to be rotatably coupled to an optical sensor, a wiper blade coupled to the housing, wherein the wiper blade is disposed at a downward angle relative to a top-surface of the optical sensor, and one or more nozzles disposed within the wiper blade, wherein the nozzles are configured to apply compressed gas to a surface of the optical sensor.

A wiper system for clearing a surface of a dome includes a plurality of wiper blades that are configured to move around a circumference of the dome. Rotation of the wiper blades in a first direction around the circumference of the dome deploys the wiper blades into an upright position and rotation of the wiper blades in a second direction opposite the first direction stows the wiper blades into a collapsed position.

A contaminant removal apparatus for windshields includes: driving belts located at both side surfaces of a windshield; a drive unit configured to apply driving force to the driving belts; a wiper assembly located on the windshield; rotary rollers configured to be shifted along the driving belts; idle gears located at ends of the driving belts to change a rotating direction of the rotary rollers; frame connection shafts coupled to both ends of the wiper assembly and located within the rotary rollers so as to contact the idle gears to change the rotating direction of the rotary rollers; and a controller configured to change a rotating direction of the rotary rollers when the idle gears and the frame connection shafts contact.

There is disclosed a viewing system coupled to a motor vehicle having a frame having a roof, at least one support, and a body with the at least one support supporting the roof over the body. The system can comprise at least one camera, at least one screen coupled to the support. In addition each camera is coupled to the at least one support and wherein said at least one screen is in communication with the first set of cameras, wherein said at least one screen displays images presented by the first set of cameras. This device can provide additional view in the blind spot of the vehicle.

The present invention relates to a telescopic cleaning device (100) for cleaning a glass surface (300) of a motor vehicle, comprising at least one hollow body (110) and a movable piston (120) configured to slide in the hollow body (110) along a deployment direction (D) between an extended position and a folded position, the movable piston being configured to support a member for cleaning the glass surface, the device being characterised in that it comprises two cleaning members consisting of a member for projecting (140) a cleaning fluid (FN) conveyed through the hollow body (110) and a wiper blade (130), the two cleaning members being rigidly connected to the movable piston.

A rotating window sensor cleaning system according to the disclosure includes: a frame having a space therein; a camera or a sensor fixed inside the frame; a transparent window arranged in front of the camera or the sensor and mounted to be rotatable with respect to the frame; and a wiper blade fixed to the frame and mounted to be in sliding contact with the window, wherein the window is configured to be rotated by a motor fixed to the frame.
