It is easier for installation by position.Meanwhile by the setting of heating device, can wiper arm be added to glass for vehicle window
Heat, remaining small water droplet on rapid evaporation glass for vehicle window, guarantees the clear of vehicle window.
The windscreen wiper axis is in cylindrical, and the side wall of windscreen wiper axis lower part is equipped with positioning key, windscreen wiper axis top
Equipped with external screw thread, the center of the interconnecting piece opens up cylindrical hole, and cylindrical hole opens up determine with what positioning key matched outward
Position slot, when installation, the interconnecting piece is set in outside windscreen wiper axis, and positioning key is located in locating slot, the windscreen wiper axis
Top fixture nut, after being installed, the bottom end of interconnecting piece is connected to the bottom of windscreen wiper axis, and the top of interconnecting piece abuts nut
Bottom end.
Be respectively equipped with the contact being mutually matched and contact in the positioning key and locating slot, the contact by route with
Automobile controller and power supply connection, the contact are connect by route with heating unit.The positioning key of the utility model and positioning
Slot is also used to transmit control signal and electric current other than for Fast Installation wiper arm, so that the operation of heating unit is controlled,
The contact that uses in the utility model, contact is common commercially available contact contacts.
The heating unit includes micro-blower and the heating wire that micro-blower air outlet is arranged in, the electric heating
Silk and micro-blower are connect by route with contact.On the one hand the wiper arm of the utility model has and is close to glass for vehicle window
Scraper plate, this with existing wiper arm be it is identical, on the other hand, open up in windscreen wiper arm body towards the side of glass for vehicle window more
Hot wind is blown out from ventilation opening and is blowed to glass for vehicle window, heatable vehicle window glass by heating wire and micro-blower by a ventilation opening
Glass is that remaining small water droplet is quickly issued additional.
The interconnecting piece is equipped with gasket with windscreen wiper axis bottom and the nut place of abutting, the setting be in order to avoid water with
And dust enters the junction of interconnecting piece Yu windscreen wiper axis, so as to cause the poor contact of contact and contact.
The section of the positioning key is in isosceles trapezoid.The shape can make the contact area of contact and contact larger,
Guarantee the transmitting of electric energy and signal.
Compared with prior art, the beneficial effects of the utility model are embodied in following several respects:
(1) cooperation for passing through positioning key and locating slot, enables wiper arm to be accurately mounted on glass theoretical position, pacifies
It fills more convenient；
(2) by the setting of heating device, wiper arm can be allowed to heat glass for vehicle window, rapid evaporation vehicle window glass
Remaining small water droplet, guarantees the clear of vehicle window on glass.
