And it is unclear to thicken, potential safety hazard is considerably increased.
Occur rearview mirror wiper blade device on the market, but because rear-vision mirror face is in irregular shape, wiper on the market
The rainwater of mirror edges can not all be struck off.
The content of the invention
For mirror with this, the utility model proposes rearview mirror wiper blade device, thoroughly removes the rainwater on rear-vision mirror face.
What the technical solution of the utility model was realized in：
Rearview mirror wiper blade device, including some scraping blades and the telescopic expansion link of length, the expansion link is by connecting together
The first bar and the second bar form, scraping blade head and the tail are be hinged and junction is provided with flexible member, divide on the first bar and the second bar
Not She You the first rod guide and the second rod guide, some scraping blades are connected to first rod guide and described by movable block
On second rod guide, first bar and the second bar are cavity structure and interior are provided with spring mountings, the first bar and second
Bar is connected by spring, and the spring free length is more than the expansion link maximum elongation length.
Further, the flexible member is torque spring.
Further, the expansion link is elastic circular arc type expansion link.
Further, the second bar end is provided with end cap.
Further, the end cap is provided with roller.
Compared with prior art, the beneficial effects of the utility model are：Because the length of expansion link can be with rearview mirror side
What the shape of frame changed, so the rainwater of mirror edges can be effectively struck off in the rainwater on striking off minute surface, after raising
The visual field of visor, eliminate driving safety hidden danger.The utility model includes some scraping blades, and only damage need to be changed after some scrapes pad wear
That bad, maintenance cost is reduced, and scraping blade is bonded closely with minute surface, and performance is good, long lifespan.

In figure, 1 is scraping blade, and 101 be torque spring, and 2 be expansion link, and 201 be the first bar, and 2011 be the first rod guide, 202
For the second bar, 2021 be the second rod guide, and 203 be spring mountings, and 3 be movable block, and 4 be spring, and 5 be end cap, and 6 be roller, 4
It is roller for end cap, 5.
Embodiment
In order to be best understood from the utility model technology contents, specific embodiment is provided below, and with reference to accompanying drawing to this practicality
It is new to be described further.
Embodiment 1
Referring to Fig. 1 to 3, rearview mirror wiper blade device provided by the utility model, including some scraping blades 1 and length is telescopic stretches
Contracting bar 2, the expansion link are made up of the first bar 201 to connect together and the second bar 202, and the scraping blade 1 is hinged and connected from beginning to end
Meet place and be provided with flexible member, the first rod guide 2011 and the second rod guide are respectively equipped with the first bar 201 and the second bar 202
2021, some scraping blades 1 by movable block 3 be connected to first rod guide 2011 and second rod guide 2021 it
On, the bar 202 of the first bar 201 and second is cavity structure and interior is provided with spring mountings 203, the first bar 201 and second
Bar 202 is connected by spring 4, and the drift of spring 4 is more than the maximum elongation length of expansion link 2.Due to the spring 4
Effect, the expansion link 2 be in tend to elongation state, Gu the end of the first bar 201 is adjacent to the picture frame of rearview mirror all the time.
In the presence of flexible member, the end to end scraping blade 1 tends to open configuration all the time.During work, expansion link 2 is along picture frame
Flexible, flexible with expansion link, the lower movable block 3 of the effect of flexible member 101 between scraping blade 1 slides on guide rail, scraping blade 1 it
Between subtended angle constantly change, but the total length of scraping blade 1 is consistently equal to the length of expansion link 2.Guarantee effectively to strike off mirror edges
Rainwater, improve the visual field of rearview mirror, eliminate driving safety hidden danger.Can be by first institute in some specific implementation processes
State the length reduction's half of scraping blade 1, and by the movable block 3 with first scraping blade 1 be fixed on the first bar 201 end, it is necessary to
What is illustrated is remote first bar 201 and the end that the junction of the second bar 202 is the first bar 201 in the first bar 201, equally will be last
Movable block 3 with the last a piece of scraping blade 1 is simultaneously fixed on second bar 202 by a piece of length reduction's half of the scraping blade 1
Head end is, it is necessary to which explanation is remote first bar 201 and the head end that the junction of the second bar 202 is the first bar 202 in the second bar 202.
So as to be further ensured that the total length of scraping blade 1 is consistently equal to length of telescopic bar, and device aesthetic property is improved, also save material.
Further, the flexible member is torque spring 101.Flexible member can be selected as shell fragment or torque spring
101 etc., every flexible member for being used to open scraping blade 1 should be in the scope of protection of the utility model, and the utility model is excellent
Choosing is torque spring 101, and torque spring 101 has the advantages that torque arm small volume, torsion are big.
Further, the expansion link 2 is circular arc type and flexible, because rearview mirror is convex mirror, circular arc type and tool
Scraping blade 1 can be tightly pressed against on minute surface by flexible expansion link 2, and it is cleaner to strike off rainwater.
Embodiment 2
Referring to Fig. 4, the difference of the present embodiment and embodiment 1 is that the end of the first bar 202 is provided with end cap 5, increase dress
That puts is attractive in appearance, and end cap 5 can be fabricated to the smooth ball-type in surface, reduces expansion link 2 and swings resistance.After the abrasion of end cap 5
New end cap 5 is changed, reduces maintenance cost.
Further, the end cap 5 is provided with roller 6, further reduces expansion link 2 and swings resistance, replaces sliding with rolling
The dynamic abrasion for also reducing part simultaneously, increases the service life.
It is well known that wiper drive system includes motor, decelerator, quadric chain, rotating shaft, resetting means etc..
The utility model need to coordinate drive system to be used together, when driver presses the switch of rearview mirror wiper blade device, motor start-up, and electricity
The rotating speed of motivation increases torsion effect driving swing arm by the deceleration of worm and gear, and swing arm drives quadric chain, quadric chain band
Turn axle swings, and finally the second bar of rearview mirror wiper blade device 202 is driven by rotating shaft, so as to drive expansion link 2 to swing, after sweeping
Endoscopy glass.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc., the utility model should be included in
Protection domain within.
