  • Publication number: 20200114881
    Abstract: An onboard sensor cleaning device includes a nozzle opening, a pump, a flow passage, an on-off valve, and a pressure accumulator. The nozzle opening ejects fluid to a sensing surface of an onboard sensor. The pump sends fluid to the nozzle opening. The flow passage connects the nozzle opening and the pump. The on-off valve is arranged in the flow passage to open and close the flow passage based on a control signal. The pressure accumulator is arranged in the flow passage in a pump-side portion that is a portion between the on-off valve and the pump.

  • Patent number: 8069527
    Abstract: A washer nozzle provided in a wiper blade has a first ejection hole ejecting a first washer fluid, and a second ejection hole ejecting a second washer fluid. A first ejection axis, which is a center line of a first ejection port angle of the first ejection hole, is define. A second ejection axis, which is a center line of a second ejection port angle of the second ejection hole, is defined. The washer nozzle is structured such that the first ejection axis and the second ejection axis intersect with each other as seen from a width direction of the wiper blade.

  • Patent number: 7836541
    Abstract: A lever of a wiper blade holds a blade rubber. A cover accommodates at least a part of the lever from an opening. A nozzle mechanism has a connecting portion connected to a supply passage. A nozzle portion receives washer liquid that has been sent from the supply passage under pressure and passed the connecting portion, and supplies the washer liquid to a surface to be wiped. An attachment member is integrated with the nozzle mechanism. In a state where the cover accommodates the nozzle mechanism, the attachment member is attached to the lever or the cover. Therefore, the wiper blade is capable of stably supplies washer liquid to the surface to be wiped for an extended period of time.

  • Patent number: 7757337
    Abstract: A pipe member is arranged along a wiper arm. A wiper blade has a lever rotatably coupled to the wiper arm and a blade rubber for wiping a surface to be wiped. A nozzle mechanism has an attachment member attached to the wiper arm, a nozzle member for supplying the washer liquid sent under pressure from the pipe member to the surface to be wiped, and an engaging portion provided in the nozzle member. The attachment member rotatably supports the nozzle member. The engaging portion engages with the wiper blade such that the nozzle member follows rotation of the wiper blade. Therefore, a vehicle wiper device facilitates replacement of the wiper blade, and allows washer liquid to be stably received by the surface to be wiped.

  • Patent number: 7735183
    Abstract: If a washer switch is turned on in a state in which a wiper determining portion determines that a wiper switch is in an OFF state, and a vehicle speed determining portion determines that a vehicle speed is equal to or more than a predetermined speed, a simultaneous operation control portion ejects the washer fluid in a state in which the wiper is positioned at a lower reversing position. The simultaneous operation control portion causes the wiper to reciprocate at least once simultaneously with the ejection. The simultaneous operation control portion additionally ejects the washer fluid at least once, in a state in which the wiper is positioned at an intermediate position between the lower reversing position and an upper reversing position. Accordingly, it is possible to inhibit a lack of the washer fluid from being generated on the surface to be wiped.

  • Patent number: 7615955
    Abstract: A washer controller controls a washer motor in accordance with a manipulation of a washer switch. A washer switch detector determines whether a manipulation of the washer switch is performed within a predetermined time period of a last manipulation of the washer switch. A spray time controller sets a spray time to a first set time when the manipulation of the washer switch is performed within the predetermined time period of the last manipulation, and to a second set time when the manipulation of the washer switch is performed after the predetermined time period, the second set time being greater than the first set time. A washer motor controller operates the washer motor for a time period corresponding to the spray time set by the spray time controller.
