Description

The preposition assistive device of windshield wiper

The utility model is the relevant preposition sweeping device of a kind of rain brush, especially the assistive device that refers to a kind of independent moulding combines with the windshield wiper seat, this assistive device is positioned at the lead position place of the cleaning approach of rain brush seat, but get high rain brush of frame and Windshield and keep a gap, avoid the rain brush scraping blade chapped by sunshine, cause shorten service life, and can be when windshield be struck off in cleaning, bristle on it can be earlier with particle type dirt or dust cleaning, so that strike off other dirts of Windshield at rain brush after, avoid the hard dirty grain of rain brush pressure zone and scratch Windshield and rain brush body, again, when brushing backhaul, can make the scraping blade established in addition on this assistive device again row once strike off water wave on glass, the auxiliary deficiency that strengthens the rain brush water-repellancy.

Common general rain brush seat major part all only is provided with rubber-type rain brush scraping blade, after will removing the dirt that windshield attaches, cause the sticking Windshield that is attached to of winged insect, birds droppings when having the graininess dust that falls in the air or driving in the dirt down with the wind, dial with simple blade insert and to produce the situation that filth is smeared when scraping, the phenomenon that frequent generation is scraped dirtier and dirtier, and the extreme hardness of part dust, dial the process of scraping at Wiper blade easily, by pressure zone in glass surface and scratch Windshield and rain brush scraping blade thereof; A kind of rain brush seat was once arranged for this reason, was to establish individual layer rain brush scraping blade on single rain brush seat, and both sides are provided with vertical single can earlier birds droppings, winged insect or dust removings when removing windshield before or after it, strike off other dirts again; Right this kind rain brush seat, to scrape hair too near at interval with rain brush brush sheet because of its hairbrush, and it is limited that single hairbrush bar is not only cleared away effect, and sweep move past the forward bent Zhe of Cheng Huiyin and cramping below Wiper blade, in the time of promptly can causing striking off Windshield, cause hairbrush to suffer the situation of rain brush scraping blade cramping, so not only can't expect and remove dust on the Windshield, the effect that the opposite effects rain brush takes out stains, and hairbrush and rain brush seat are one-body molded, when damaging, the part can't separate replacing, whole renewing then forms unnecessary waste, and the device that bristle is set in the place ahead of rubber rain brush is arranged again recently, yet though this bristle can preposition removing dust, but when sweeping to backhaul, bristle but stays the water wave that can't clear away because of its clearance, and is carrying water wave and dust secretly because of bristle when brushing backhaul, and causes Windshield to brush dirtier and dirtier, have a strong impact on sight line, be necessary to be improved for this reason.

The purpose of this utility model is promptly providing a kind of windshield wiper preposition assistive device.

The purpose of this utility model is achieved in that the utility model mainly is made up of institutes such as assistive device, cohesive frames.It can be by a detachable preposition assistive device; installation is bonded on the rain brush seat of automobile; press the preposition orientation of sweeping with the control bristle in Wiper blade; make when removing windshield; its bristle can be earlier with particle dust or birds droppings on the windscreen surface; winged insect is removed; in order to subsequently and the row the rain brush scraping blade strike off Windshield printing ink and other more tiny dirts; and when brushing backhaul, can make the scraping blade on the assistive device strike off water wave on glass again at last; the auxiliary deficiency that strengthens the rain brush water-repellancy; avoid the above-mentioned damage Windshield of scraping; the situation that random sheet of rain brush and water wave influence sight line takes place; and, can reduce unnecessary waste because it can upgrade separately for separate component design.

As for detailed construction of the present utility model, application principle, effect and effect, then the explanation of doing with reference to following accompanying drawing can be understood completely:
