Description

The adapter that is used for swept area of wiper blade

Technical field

The present invention relates to a kind of being used for the main segmental support of swept area of wiper blade and the suitable adapter of linkage section of the wiper arm of the wiper device that is used for flat swept area of wiper blade.

Background technology

The automobile that has the wiper device with so-called flat swept area of wiper blade is subjected to increasing popularization.The feature of flat swept area of wiper blade is, it does not have the segmental support system of tandem type, but has the elastic supporting element of one or more correspondingly prebucklings along the swept area of wiper blade longitudinal extension.Be fitted on the glass port surface to be cleaned on its whole length with its water wiping lip mouth at this swept area of wiper blade under the thrust effect.At this moment produce a stress in elastic supporting element, it is used for making wiper strip to be fitted on the glass port suitably on its whole length.

For this flat swept area of wiper blade is fixed on the free end of wiper arm, known by WO00/73113A1, the linkage section of wiper arm is done to such an extent that make the boss of L shaped or U-shaped with the swivel pin and of a single-ended installation in cross-sectional plane.Here boss has a side backstop that distributes perpendicular to the swivel pin longitudinal axis, and it vertically is arranged on axis a distance from swivel pin along wiper arm.By this special construction of wiper arm adaptor union and the complementary structure of swept area of wiper blade canned paragraph, described in WO 00/73113A1, can reach rapidly and easily by the revolution of swept area of wiper blade and unclamp.

Yet actual showing, the flat swept area of wiper blade that is specifically designed to it can only be installed on the linkage section of this wiper arm.Because the width of flat swept area of wiper blade is smaller, they can only be used under the certain condition.

Summary of the invention

Therefore the objective of the invention is, make a kind of terms of settlement that is used for this situation, make and in the time can not using flat swept area of wiper blade, scrub normally with custom-designed canned paragraph assurance glass port.

This purpose realizes by such adapter, this adapter has the bearing pin that extends perpendicular to the swept area of wiper blade longitudinal axis that is used to peg graft between the sidewall of main cambered plate, one has the single-ended section of the being fixedly coupled swivel pin side direction insertion and the cylinder shape groove that as far as possible seamlessly supports perpendicular to the extension of the swept area of wiper blade longitudinal axis that be used for of an insertion mouth, wherein in inserting port area, be provided with one first applying section, so that and fit in the zone of the pin that is fixedly hinged of linkage section, and adapter has one and is arranged on dorsad and inserts the section of fitting of second on the inlet side, so that and the fitting in the backstop that confined state is local at least and adapter is overlapping of linkage section.

The known arc swept area of wiper blade that whole world general-duty uses in decades advantageously reaches thus, even also can be installed in the wiper arm of the wiper device that is used for flat swept area of wiper blade always.Therefore because the flat swept area of wiper blade that adapter of the present invention need not itself be provided with by operational arc swept area of wiper blade also can reach the reliability of corresponding vehicle operating.For installation adapter with adapter from the top that is from being enclosed within on the bearing pin of main segmental support back to a side of Windshield plug socket with its transversal slotting.At this moment plug socket tightens with bearing pin goodly.

For swept area of wiper blade can be turned round conditionally with respect to wiper arm, if first and/or second section of fitting is done along horizontal projection in this wise, make the respective side walls that under confined state, protrudes in main segmental support, this is favourable.Realize the contact point stipulated between adapter and the linkage section thus.Here the first applying section is preferably disposed on along swept area of wiper blade vertically from second an applying section a distance.

Here the cylinder shape groove that is used to install the wiper arm swivel pin can be made for example through hole or blind hole.The swivel pin of wiper arm adopts blind hole because can only insert cylinder shape groove from a direction.The reliability that helps assembling.It is favourable when blind hole is set as cylinder shape groove one deflation hole being set in the blind hole bottom section.Can drain the rainwater of for example invading in the blind hole thus.

For assurance power symmetry is also imported swept area of wiper blade into, cylinder shape groove is preferably disposed on the plug socket top.Here the axis of the axis of cylinder shape groove and the plug socket distribution that preferably is parallel to each other.

If adapter to small part is arranged between the sidewall or in the suspension basket of main segmental support, installs just obtain the adapter failure-free so under confined state.

According to the opening size of main segmental support width or wiper arm canned paragraph, the second applying section of adapter has the side plate of at least one projective table type, and it surrounds a sidewall of main segmental support at least conditionally at confined state.The side force that acts on the swept area of wiper blade is imported in the wiper arm reliably.

According to the form of implementation of main segmental support and wiper arm linkage section, the section of fitting is made L shaped or U-shaped in cross-sectional plane.

For zero-lash guiding between the linkage section that reaches adapter and wiper arm and/or main segmental support, in another kind of form of implementation of the present invention, imagine, the section of fitting along the width of lateral extent under confined state by the boss of the linkage section of wiper arm and backstop as far as possible shape surround sealedly.

Adapter is under confined state or can rotate and be fixed on regularly on the main segmental support, perhaps rotation is fixed on the wiper arm regularly, if the adapter rotation is fixed on the wiper arm regularly, this has such advantage so, i.e. wearing and tearing appear on the part of the motion between swept area of wiper blade and the adapter.Therefore wear-out part is to change part.The linkage section of wiper arm is just not frayed.

Can consider in order to rotate regularly fixing adapter, make adapter have at least one and be used for kayser section with the boss or the backstop kayser of main segmental support or wiper arm.If wherein this kayser section or these kayser sections are arranged on second to fit at least one side plate of the section or the section of fitting are favourable.

In order to reach the reliable kayser on main segmental support or boss, it is contemplated that this kayser section or these kayser sections are arranged on the free end or each free end of side plate of the corresponding section of fitting.

If adapter has a ring edge on its end face, it hides a suspension basket that exists especially fully being contained on main segmental support under the state of main segmental support.Prevent that thus dirt or particulate from entering in the suspension basket, and may the function of swept area of wiper blade be had a negative impact.
