The automobile windscreen wiper is used for removing rain, snow or dust on automobile glass so as to ensure good visibility of a driver. The common electric windscreen wiper mainly comprises a direct current motor, a worm gear box, a crank, a connecting rod, a swing rod, a wiper blade and the like. The wiper blade is directly contacted with windshield glass, the utility model discloses mainly improve to the wiper blade. Referring to fig. 1 to 3, the wiper arm of the present invention is provided with the following embodiments:
in some embodiments, a wiper arm comprises a rubber strip mounting member, a framework 200 and a wiper blade assembly, wherein the rubber strip mounting member comprises a plurality of mounting bars 100 which are movably connected in sequence; the bottom of the framework 200 is provided with a plurality of connecting ends which are respectively connected with the mounting bars 100; the doctor blade subassembly includes the rubber strip body 300, sets up shell fragment 400 in the rubber strip body 300, and the rubber strip body 300 is installed on a plurality of mounting bars 100.
When the installation strip is used, the framework 200 is connected with the swing rod of the windscreen wiper, the plurality of supporting points of the framework 200 are pressed towards the installation strip 100, and the installation strip 100 transmits force to the rubber strip body 300 so that the rubber strip body 300 is pressed on glass. Along with the swing of the swing rod, the rubber strip body 300 swings relative to the windshield, so that the function of cleaning the windshield is achieved. The utility model discloses a skeleton 200 can make the pressure of each strong point on the adhesive tape body 300 average, and can increase the windscreen wiper arm and bear the pressure, set up many mounting bars 100 that contain shell fragment 400 and the swing joint in the adhesive tape body 300 simultaneously, when meetting different radian and barrier, adhesive tape body 300 can take place bending deformation correspondingly with swing joint's mounting bar 100 in proper order, skeleton 200 has again to provide sufficient pressure, the adhesive tape can closely laminate with windshield more, the cleaning performance is better.
Specifically, there are nine mounting bars 100, and mounting bar 100 is arranged from left to right in proper order, roughly is a straight line, swing joint between mounting bar 100 and the mounting bar 100, specifically accessible hinge structure swing joint. In other embodiments, the mounting bars 100 and the mounting bars 100 may also be movably connected by a snap structure, for example, two of the mounting bars 100 are provided with a snap groove, the other mounting bar 100 is provided with a snap block, the snap block is movably snapped in the snap groove, the snap groove is slightly larger than the snap block, and the snap block is loosely snapped in the snap groove. The plurality of substantially linear mounting bars 100 may be partially curved when encountering an obstacle or a curved glass surface.
It should be noted that the utility model discloses do not do the restriction to the specific quantity of mounting bar 100, increase the quantity of mounting bar 100, can take place less bending deformation between mounting bar 100 and the mounting bar 100 to when making the colloid body 300 meet the barrier, the local emergence can bending deformation, and be exactly that the bending deformation takes place for a segment in the linear arrangement, other sections can still be the arc or the linear better laminating is on glass.
The plurality of mounting bars 100 are used for mounting and fixing the adhesive tape body 300, the elastic sheet 400 arranged along the extending direction of the adhesive tape body 300 is arranged in the adhesive tape body 300, and the adhesive tape body 300 is in direct contact with a windshield. The rubber strip body 300 is made of rubber, and the elastic piece 400 is made of a stainless steel elastic piece, so that the elasticity is better. Furthermore, the contact surface of the rubber can be attached to the glass surface less, so that wiping residues are reduced; and the glass surface will not present water film state and generate fine stripe, fog and linear residue after wiping. Further, the lower extreme personally submitting of adhesive tape body 300 is the arc, laminates with windshield better to can be complete scrape sweep work to glass, clear away rainwater and dirt on the glass.
Furthermore, the rubber strip 300 can not be used for cleaning the windshield well after being used for a long time, the cleaning of the windshield is very important, especially in rainy days, the effect of cleaning the windshield is poor, the visual field of a driver is blurred, driving is affected, and more serious traffic accidents can be caused. The wiper arm is therefore replaced in good time. The utility model discloses a reduce and change the old book, with the adhesive tape body 300 demountable installation in mounting bar 100. Can need not wholly change the wiper arm, only change the doctor-bar subassembly alone can, adhesive tape installed part and skeleton 200 can use repeatedly, prolong adhesive tape installed part and skeleton 200's life. Specifically, mounting bar 100 is provided with the mounting groove, and the adhesive tape body 300 joint in the mounting groove, adhesive tape body 300 have certain elasticity, and the joint is fixed more steady.
The framework 200 comprises a main bone 210, a plurality of secondary bones 220 and a plurality of small arms 230, wherein the main bone 210, the secondary bones 220 and the small arms 230 are all arranged in an arched bending mode, two ends of each small arm 230 are connected with the rubber strip mounting pieces, the top ends of the small arms 230 are connected with two ends of each secondary bone 220, and two ends of the main bone 210 are connected with the top ends of the secondary bones 220. The pressure to provide the adhesive strip body 300 is increased by the double-layer skeleton stack structure.
More specifically, there are eight small arms 230, and both ends of the small arms 230 are connected to two of the mounting bars 100, respectively. The main bone 210 is provided with one main bone, and the middle position of the top end of the main bone 210 is provided with a connecting structure, wherein the connecting structure comprises a snap fastener structure, a threaded connecting structure and the like; the number of the secondary bones 220 is two, the number of the small arms 230 is eight, and the rubber strip body 300 has eight stress points. Wherein, the top end of the small arm 230 is hinged with the two ends of the secondary bone 220, and the two ends of the main bone 210 are hinged with the top end of the secondary bone 220. Without rigid connection, the connection part can be slightly deformed, which is beneficial for the adhesive tape body 300 to press to the glass.
In other embodiments, the both ends joint of forearm 230 is in the adhesive tape installed part, and the both ends of forearm 230 are provided with the mounting groove promptly, and the mounting groove joint is in the adhesive tape body 300 to still connect through rivet fixed, make the both ends of forearm 230 more firm with the installed part of adhesive tape installed part.
