    摘要: Disclosed is an optical window cleaning device, including: a cleaning brush; and a wiper arm. The wiper arm includes a first link, a torsion mechanism, a second link and a wiper arm drive system. A second end of the first link is hinged to a first end of the second link. The cleaning brush is hinged to a first end of the first link, a rotation trajectory of the cleaning brush and a rotation trajectory of a hinge joint between the second end of the first link and the first end of the second link are both located in a first plane. A rotation trajectory of the second link and the rotation trajectory of the hinge joint are located in the first plane. The torsion mechanism provides the first link and the second link with a force that rotates the first link relative to the second link.

    摘要: An electroplating method for producing magnetic conducting materials, such as charging coils used in induction charging of electronic devices, comprising the following steps: constant tension releasing conducting material, such as cooper wire, the conducting material then undergo these process: alkaline washing then clean water washing, degreasing, acidic washing then clean water washing, continuous plating, clean water washing, drying, infrared measuring the diameter and retracting the conducting material. The method allows electroplating preparation of uniform and dense distribution of iron and nickel coating layer on the surface of conducting material, wherein, the thickness of the coating layer is 2˜10 μm. Since the conducting material is non-magnetic, but through the electroplating preparation, the entire charging coil is magnetized to become magnetic material, which when used during induction charging provides the coil with electro resistance that reducing high-frequency skin effect and improving electro induction.
