Then the U-shaped hook on the end part of the sweep arm is clamped into the U-shaped groove of the connecting clip; in the assembling process, the connection structure can be conveniently assembled only by rotating the doctor blade and carrying out corresponding push-pull action; and the structure is convenient to disassemble.
Description
Technical field
The invention belongs to the automobile water wiper system, be specifically related to the connection structure of Windshield Wiper scraping arm and scraping blade.
Background technology
Along with automotive market constantly develops, the customer requires increasingly high to the details of automobile design.It is less that at present general common scraping blade Connection Card outside and windscreen wiper sheet skeleton edge joint touch area, the scraping blade easy shaking, and during installation and removal need with the hole clipping of Connection Card subcard button from scraping arm by going out.It is very inconvenient when scraping arm is installed.
Scraping arm generally adopts a kind of clamp that connects to realize with being connected of scraping blade in the wiper system of automobile.Inconvenient problem when common connection clamp ubiquity and scraping arm installation and removal, as shown in Figure 5, comprise press handle 10 in the common connection clamp, its effect be for snap close 11 from the hole of scraping arm by going out.The effect of snap close 11 is to connect on the clamp for scraping arm is fixed on.The effect of rotating hole 12 is to be connected on the scraping blade in order to connect clamp, when the scraping arm installation and removal, can rotate along rotating hole.When dismounting, need will connect earlier clamp along rotating hole 12 rotations, the press handle 10 that will connect then on the clamp is inwardly pushed, so that withdraw from the hole of snap close 11 from scraping arm on the clamp to accomplish dismounting.Inconvenient, as shown in Figure 6 during the scraping blade dismounting.
Summary of the invention
The objective of the invention is to be connected clamp installation and removal problem not too easily to what connect scraping arm and scraping blade in the existing wiper system.A kind of connection structure of scraping arm and scraping blade of new structure is provided.
Technical scheme of the present invention is following
A kind of scraping arm of automobile water wiper and scraping blade connection structure, the connection clamp that it comprises scraping arm, scraping blade and is connected both, said connection clamp is a U-shaped spare.Be formed with the deep-slotted chip breaker of a pair of symmetry on the two side, middle part of the U-shaped opening of said connection clamp, as with the scraping blade S. A. bonded assembly axis hole of lacing film.The outer wall on the U-shaped limit of said connection clamp inwardly is formed with the U-shaped groove one, as the end bonded assembly draw-in groove hook-shaped with the U-shaped of scraping arm.The notch inner wall position that is positioned at U-shaped spare bottom at said draw-in groove is symmetrically arranged with buckle, sticks into and is fixed in the draw-in groove through the end of buckle with scraping arm.
Further, the bottom land position that is positioned at U-shaped spare bottom at said draw-in groove is provided with the elastic compression piece, pushes down scraping arm from the inside of the U-shaped hook of scraping arm end.
Further again, said draw-in groove is provided with symmetrical spacing rib at the notch inner wall position of a side of U-shaped, through terminal spacing be blocked in draw-in groove in of spacing rib with the U-shaped hook of scraping arm end.
In addition, said buckle is shaped as outer low and inner high cammed surface.
During installation, connect clamp and be connected with the scraping blade S. A. of lacing film through axis hole earlier, promptly install on the scraping blade.U-shaped dogging with the scraping arm end advances to connect in the U-shaped draw-in groove of clamp then, in fitting process, as long as rotate scraping blade and and carry out corresponding push pull maneuver and just assemble very easily, dismounting is very convenient.
Therefore, connection structure has easy accessibility, advantage of simple structure through improving the Connection Card substructure of scraping arm and scraping blade.

The specific embodiment
Referring to Fig. 2, this scraping arm comprises scraping arm 7, scraping blade 9 with the scraping blade connection structure and is connected both connection clamps 8.
Referring to Fig. 1, connecting clamp 8 is the U-shaped spare of integrated injection molding, has certain thickness.Connect the deep-slotted chip breaker that is formed with a pair of symmetry on the two side, middle part of U-shaped opening of clamp 8, as with the scraping blade S. A. 13 bonded assembly axis holes 3 of scraping blade 9.The outer wall that connects the U-shaped limit of clamp 8 inwardly is formed with the U-shaped groove one, as the end bonded assembly draw-in groove 2 hook-shaped with the U-shaped of scraping arm 7.The notch inner wall position that is positioned at U-shaped spare bottom at draw-in groove 2 is symmetrically arranged with buckle 1, buckle 1 be shaped as outer low and inner high cammed surface, stick into and be fixed in the draw-in groove 2 through the end of buckle 1 scraping arm 7.The bottom land position that is positioned at U-shaped spare bottom at draw-in groove 2 is provided with elastic compression piece 5, pushes down scraping arm 7 from the inside of the U-shaped hook of scraping arm 7 ends.Draw-in groove 2 is provided with symmetrical spacing rib 4 at the notch inner wall position of a side of U-shaped, is blocked in draw-in groove 2 through the terminal spacing of U-shaped hook of spacing rib 4 with scraping arm 7 ends.
The assembling of scraping arm 7, scraping blade 9, connection clamp 8 is as shown in Figure 3: the axis hole 3 that connects in the clamp 8 is connected with scraping blade S. A. 13, connects clamp 8 and can rotate along axis hole 3 in scraping blade 9 junctions, to guarantee that scraping blade 9 is fully fitted with glass in the wiper process.During assembling, the axis hole 3 that at first will connect in the clamp is connected to scraping blade S. A. 13.So just can accomplish and connect being connected of clamp 8 and scraping blade 9.Again scraping arm 7 is assembled on the U-shaped draw-in groove 2 that connects clamp 8.When mounted, will connect clamp 8 earlier and rotate certain angle along axis hole 3.The front end of the end U-shaped hook portion of scraping arm 7 being aimed at the fluting 2 that connects clamp pulls back, and shown in Fig. 4, the cammed surface that at this moment connects the buckle 1 of draw-in groove 2 on the clamp 8 is opened to both sides by scraping arm 7 extruding.Scraping arm 7 can get into the inboard of buckle 1.Buckle 1 returns to original state, when scraping arm 7 is installed to the draw-in groove 2 that connects on the clamp 8, scraping blade 9 is returned to initial position.Since connect between clamp 8 and the scraping arm 7 gapped, so, be provided with a compression blocks 6 at the bottom land of the draw-in groove 2 that connects clamp 8 with spring function, when scraping arm 7 when being connected clamp 8 and being seated, compression blocks 6 is compressed with the elimination gap by scraping arm 7.Simultaneously, through fixing scraping arm 7 ends of two on the draw-in groove 2 spacing ribs 4, rock to prevent scraping arm 7.
Scraping arm 7 is anti-operations of its installation with the dismounting of scraping blade 9.At first will connect clamp 8 and be the axle rotating certain angle along axis hole 3
,Directly to extrapolation, the buckle 1 that scraping arm 7 will connect clamp 8 two ends this moment pushes so that it outwards opens with scraping arm 7.Scraping arm 7 can take out from connect clamp 8, promptly accomplishes its dismounting.
