Description

Wiper head

The utility model relates to a kind of self-propelled vehicle annex, refers to that especially there is hairbrush a kind of scraping blade both sides, and the rain brush that can swing automatically,

General rain brush is to drive Wiper head by fork to swing, and wipes rainwater or dust on the glass for vehicle window off.Wiper head is made up of press strip and blade insert.When swinging, scraping blade overturns automatically by the elasticity of rubber.Because rubber is aging, the root of scraping blade very easily ruptures under the situation that repeats to bend; In addition, fine dust and the sandstone that on glass and scraping blade, accumulates, glass and scraping blade can scratch and wear and tear when starting rain brush the rainy day.

The purpose of this utility model is that a kind of inlay card seat that can swing automatically that has will be provided, the Wiper head of scraping blade both sides band wool top brush.It is hinged on the fork of rain brush, can improves the service life and the protection glass for vehicle window of scraping blade effectively.

The purpose of this utility model is achieved in that Wiper head mainly is made up of beam column, inlay card seat, wool top brush, scraping blade.There are one and fork pivotally attached through hole in the centre of beam column, on the symmetrical center line of bottom surface, be fixed with several columniform positioning seats, each positioning seat has identical eccentric through-hole, and have the symmetry groove, it is characterized in that: the top of inlay card seat is a columniform beam, be inserted in the positioning seat and can swing, the groove of a reversed convex type is arranged in the middle of the bottom, respectively there is a through hole that has symmetrical channels both sides, the brush body of wool top brush is columniform,, build-in has bristle side by side above, and it is inserted in the through hole of inlay card seat both sides and can swings, scraping blade is a Rubber Parts, there is Baltimore groove the both sides, top, can snap in exactly in the reversed convex type groove of inlay card seat, and the bottom is triangular prism shaped tongue piece, the tongue piece front end is very thin, the tip of the tongue rounding off.

When Wiper head is hinged to bearing pin on the fork of rain brush, when swinging with it, the inlay card seat is swing thereupon also, makes the root of tongue piece no longer bear the bending of repetition; Because when the shutoff of wool top brush, rain brush startup; between glass and tongue piece, there are not dust and sandstone; in the swing; dust on glass and sandstone are brushed by the wool top brush in advance; do not have the scuffing of dust and sandstone and wearing and tearing glass and tongue piece yet; thereby can improve the service life of tongue piece effectively, also protect glass for vehicle window simultaneously.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is a lateral plan of the present utility model.

Fig. 3 is an action scheme drawing of the present utility model.

Mainly form referring to Fig. 1,2 Wiper heads by beam column 1, inlay card seat 2, wool top brush 3, scraping blade 4.There are one and fork pivotally attached through hole 11 in the centre of beam column 1, on the symmetrical center line of bottom surface, be fixed with several columniform positioning seats 12, each positioning seat 12 has identical eccentric through-hole 13, and have the symmetry groove, it is characterized in that: the top of inlay card seat 2 is that a columniform beam 21 is inserted in the positioning seat 12 and can swings, and the groove 22 of a reversed convex type is arranged in the middle of the bottom, and respectively there is a through hole 23 that has symmetrical channels both sides.The brush body of wool top brush 3 is columniform, and build-in has bristle side by side above, and it is inserted into through hole 23 interior can the swings of inlay card seat 2 both sides.Scraping blade 4 is Rubber Parts, and there is Baltimore groove 41 both sides, top, can snap in exactly in the reversed convex type groove 22 of inlay card seat 2, and the bottom is triangular prism shaped tongue piece 42, and tongue piece 42 front ends are very thin, the tip of the tongue rounding off.

Referring to Fig. 1,3, when swinging with it on the fork that Wiper head is hinged to rain brush with bearing pin, inlay card seat 2 is swung thereupon, makes the root of tongue piece 42 no longer bear the bending of repetition; Owing to a mao shutoff of washing brush 3, when rain brush starts, between glass and tongue piece 42, there are not dust and sandstone, in the swing, dust on glass and sandstone are brushed by wool top brush 3 in advance, also do not have the scuffing of dust and sandstone and wearing and tearing glass and tongue piece 42.Thereby can improve the service life of scraping blade 42 effectively, also protect glass for vehicle window simultaneously.
