A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

A wiper including wiper bracket which couples a wiper arm to blade carrier which carries one or more blades and includes an internal flow path which conducts fluid from a wiper bracket inlet through a hollow passage in a wiper blade carrier cover to plurality of outlets aligned with passthroughs in the blade carrier through which fluid egresses from the wiper.

The disclosure is a wiper structure. The main wiper frame includes a fixing seat. A pair of secondary wiper frames is connected to two ends of the main wiper frame. Each secondary wiper frame includes a flexible sheet. The flexible sheet is disposed with sliding troughs. A length of the sliding trough is greater than a width of the sliding trough. Multiple engaging frames are evenly disposed on each secondary wiper frame. Each engaging frame includes a pressing wing and a sliding block. The sliding block includes a neck bar with a passing diameter. The passing diameter is less than the trough width. The sliding block of each engaging frame passes through the opening and abuts against each sliding trough through the neck bar. The sliding block is slidable in each sliding trough with a change of an external force exerted on corresponding one of the secondary wiper frames.

The technology relates to a system for clearing a sensor cover. The system may comprise a wiper comprising a wiper support, a wiper blade, and a sensor cover. The wiper blade may be configured to clear the sensor cover of debris, and the sensor cover may be configured to house one or more sensors. A wiper motor may rotate the wiper and a sensor motor may rotate the sensor cover. The system wiper blade may comprise a first edge attached to the wiper support and a second edge which may be configured to be in contact with the sensor cover. The wiper blade may extend in a corkscrew shape around the wiper support. The wiper motor may be configured to rotate the wiper in a first direction and the sensor motor may be configured to rotate the sensor cover in a second direction opposite the first direction.

A vehicular windshield wiper control system includes a camera disposed at a vehicle and viewing through a windshield of the vehicle and an electronic control unit (ECU). Electronic circuitry of the ECU includes an image processor. The system, based on processing of image data captured by the camera, is operable to determine presence of a substance at an outer surface of the windshield. The system includes a windshield wiper having a rubber wiping blade and a cleaning element. The system is operable to (i) cause the rubber wiping blade to engage the windshield and/or (ii) cause the cleaning element to engage the windshield. Responsive to determining presence of the substance, the system causes the cleaning element to engage the windshield. With the rubber wiping blade and/or cleaning element engaging the outer surface of the windshield, the system moves the rubber wiping blade and/or cleaning element along the windshield.

Described is a windshield wiper apparatus that is formed to dispense fluid. The wiper apparatus includes an elongate body member having a length with a sealable channel therein that runs along the length. At least one blade protrudes downward along the length of the elongate body member. Further, a series of holes are formed such they pass from the sealable channel and through the elongate body member proximate the at least one blade. Thus, a fluid passing through the sealable channel is dispensed onto a surface proximate the at least one blade.

The present invention relates to a windshield wiper blade device primarily comprised of a body further comprised of at least one channel, a first blade insert, a second blade insert, a cleaning attachment that is received by the second blade insert and a wiper attachment mechanism. The first and second blade inserts are generally T-shaped and can each be placed into a T-shaped channel within the body. The first blade insert acts as a traditional windshield wiper blade and the second blade insert comprises a generally cylindrical cleaning attachment. The cleaning attachment is positioned in front of (i.e., closer to the windshield than) the first blade insert, such that the cleaning attachment dislodges any insects or heavy debris on the windshield before the first blade insert cleans precipitation off of a windshield.

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.
