Abstract
The invention relates to a hydraulic wiper blade which comprises a rubber strip. The back surface of the rubber strip is fixedly connected to a pressure spring; a hydraulic chamber is formed by surrounding a cavity casing with rod-shaped outer appearance and groove-shaped cross section and the pressure spring and filled with liquid; a cylinder part for accommodating a piston is arranged on the cavity casing; and the piston is positioned at the exposed outer part and matched with a wiper rod in a clipping manner. The invention adopts the cavity casing to replace the prior framework structure and utilizes the principle of hydraulic power transmission to ensure that the pressure from a wiper arm uniformly acts on the rubber strip of the wiper blade, thereby reducing the generation of drain marks and greatly improving the scraping cleanliness and the service life of the wiper blade.
Description
Technical field
The present invention relates to automotive field, especially a kind of hydraulic wiper blade.
Background technology
At present, the windscreen wiper sheet is divided into two kinds of skeleton type windscreen wiper and no bone windscreen wipers (also being flat scraping blade), the transmission of pressure of the two all is to be delivered on the interface arrangment of scraping blade by point on the floating rule, and then by skeleton structure or stage clip (steel disc, or title elasticity sliver) power is delivered on the adhesive tape.
Skeleton structure or stage clip are because its rigidity is limited, and power can't well-proportionedly be delivered to each point on the scraping blade, and adhesive tape each point discontinuity on the scraping blade causes having produced a lot of water waves, and cleanliness is scraped in influence.Simultaneously, the pressure inequality also is the basic reason that shake, abnormal sound produce.
In addition, the cost of flat scraping blade is relatively more expensive, and the technical requirements height, and the processing technology complexity is mainly reflected on the stage clip (steel disc) that transmits pressure.The material of stage clip, shape and job operation all have very harsh requirement, satisfy simultaneously that the product of elasticity and Corrosion Protection is domestic not to be had substantially, external similar product also involves great expense, especially it must bend to arc through complicated processing methods such as bakingout process, difficulty is bigger, and the possibility of bounce-back is arranged with the prolongation of period of service.
Summary of the invention
The object of the present invention is to provide and a kind ofly guarantee that the scraping blade adhesive tape is stressed evenly, improve scraping blade and scrape the hydraulic wiper blade of cleanliness.
For achieving the above object, a kind of hydraulic wiper blade provided by the invention, comprise adhesive tape, the back side of adhesive tape is fixedly connected on the stage clip, chamber shell and stage clip that profile is shaft-like channel-section surround the formation hydraulic cavities, filling liquid in the chamber, chamber shell are provided with the cylinder portion that holds piston, and piston is in the outside that appears shape and cooperates with the floating rule clamping.
The present invention adopts the chamber shell to replace original skeleton structure, utilizes the principle of hydraulic pressure power transmission, and the pressure that comes from scraping arm is acted on the adhesive tape of scraping blade very equably, has reduced the generation of water wave, has improved scraping cleanliness and service life of scraping blade greatly.

The specific embodiment
A kind of hydraulic wiper blade, comprise adhesive tape 10, the back side of adhesive tape 10 is fixedly connected on the stage clip 20, the front of adhesive tape 10 is close on the windshield in the car outside, adhesive tape 10, stage clip 20 is the strip that the curved surface with windshield matches, the chamber shell 30 that profile is shaft-like channel-section surrounds the formation hydraulic cavities with stage clip 20, filling liquid 40 in the chamber, liquid 40 adopts the less liquid of thickness power, and as machine oil etc., chamber shell 30 is provided with the cylinder portion 35 that holds piston 31, between piston 31 and the chamber shell 30 sealing is set, to prevent that liquid 40 from flowing out in chamber shell 30, piston 31 is in the outside that appears shape and cooperates with floating rule 50 clampings, as Fig. 1,2, shown in 5.
In conjunction with Fig. 2,3,5, the appearance profile of described chamber shell 30 is roughly T-shaped, the side that chamber shell 30 is positioned at stage clip 20 is strip, described cylinder portion 35 is cylindrical, offer 40 through holes that flow through 32 for liquid on the position that connects with the chamber shell 30 of strip in the cylinder portion 35, the flow that through hole 32 on the other hand also can confined liquid 40 is set, guarantee that floating rule 50 is pressing down piston 31, in the time of liquid that piston 31 presses down 40, liquid 40 can be exerted pressure to stage clip 20 equably, and causing to avoid the position out of the ordinary unbalance stress on the stage clip 20 can't the scraping water wave.Described piston 31 is in and fixedly installs U-link 33 on the outside that appears shape, buckle 34 is connected on the U-link 33, and can on U-link 33, rotate up and down, the shape of the elastic opening formula bayonet socket 51 of the shape of buckle 34 opening parts and the club head setting of floating rule 50 matches.
In conjunction with Fig. 2,4, described chamber shell 30 is positioned at and offers the notch 36 that can move up and down for buckle 34 on the cell wall of floating rule 50 1 sides, the width of notch 36 is slightly larger than the width of buckle 34, the path of motion of the degree of depth of notch 36 and buckle 34 matches, this structure can be avoided when buckle 34 drives piston 31 up-and-down movements, and buckle 34 breaks away from U-link 33 or liquid 40 outer-flowing phenomenons take place.
Below in conjunction with Fig. 1,2,3,4,5, the present invention is further illustrated.
During work, the bayonet socket 51 and the buckle 34 of floating rule 50 blocked mutually, the spring 52 of floating rule 50 applies pressure to scraping arm 53, exert pressure to piston 31 by scraping arm 53, piston 31 presses down the liquid 40 in the chamber shell 30, and liquid 40 transfers the pressure on the stage clip 20 again, finally makes adhesive tape 10 stressed even.Because liquid possesses flowing power, shape arbitrariness and incompressibility, in the solid, liquid, gas three-state, liquid helps the transmission of power most.The present invention utilizes hydraulic principle, act on the pressure of scraping arm 53 on the adhesive tape 10 of scraping blade equably by the liquid in the chamber shell 30 40, reduce the generation of water wave, improve scraping cleanliness and service life of scraping blade, simultaneously, the present invention uses common steel bar can satisfy the pressure requirement, need not to use specific steel and bends to the stage clip of arc greatly, greatly reduces productive costs.
In sum, core of the present invention is to transmit by the liquid in the chamber shell 30 40 pressure of scraping arm 53, guarantees that adhesive tape 10 is stressed even, when cleanliness is scraped in raising, has reduced shake effectively, has prolonged the service life of scraping blade.
