Technical Field

The invention relates to the technical field of wiper systems, in particular to an improved boneless wiper blade.

Background

With the continuous development and progress of automobile wiper systems, consumers have made higher and higher demands on wipers. From the previous boney wipers to the now popular boneless wipers. Both the boney wiper and the boneless wiper have their own disadvantages and drawbacks. The boned windscreen wiper has a firm structure, the whole wiper blade has strong rigidity, is not easy to deform and damage, but has an unattractive appearance, high whole height, multiple parts and troublesome assembly; the boneless wiper has good wiping effect, is easy to hide, has beautiful appearance, but has poor structural compactness, is easy to deform, and the overall pressure distribution of the wiper is not easy to control. The market has thus become more and more demanding for new boneless wipers.

At present, the traditional boneless wiper blade adopts an assembly mode of two spring pieces, and the structure is complex.

Disclosure of Invention

The invention aims to solve the technical problem of providing an improved boneless wiper blade aiming at the problems of the conventional boneless wiper blade. It has changed traditional spring leaf design, has cancelled the equipment mode of traditional boneless wiper blade two spring leaves, and changes into single spring leaf design, sets out fixing base pilot hole and a certain amount and evenly distributed's stopper mounting groove on the spring leaf, and the fixing base passes through rivet riveting on the spring leaf, and the stopper is pressed into behind the spring leaf through the frock interference and is prevented moving back the back-off bounce, guarantees to assemble firmly reliably. The number of the limiting blocks is set according to the length of the wiper blade. Still improve the assembly methods of traditional boneless wiper blade adhesive tape, wear the stopper of certain quantity for the adhesive tape with its design, stopper is more for pressure distribution is even, scrapes the brush effect better.

The technical problem to be solved by the invention can be realized by the following technical scheme:

an improved boneless wiper blade comprises a connecting piece, a fixed seat, a pair of turbulence wings, a pair of reeds and an adhesive tape, wherein the connecting piece is hinged on the fixed seat, and the pair of reeds are assembled in the adhesive tape to support the adhesive tape; it is characterized by also comprising a spring piece and a plurality of limiting blocks; the fixed seat is fixedly riveted on the middle position of the spring piece, and the pair of turbulence wings are respectively arranged on the left side and the right side of the fixed seat and assembled on the spring piece; the rubber strip is installed on the spring plate through the limiting blocks.

In a preferred embodiment of the present invention, each of the limiting blocks has a flat plate portion, vertical portions located at two opposite sides of the flat plate portion, and a hook portion of the adhesive tape located at the bottom of each of the vertical portions; the spring piece is followed the length direction interval of spring piece is equipped with a plurality of groups stopper mounting hole, and every group stopper mounting hole is two, and the concrete mode that the stopper assembled on the spring piece is: the two vertical parts penetrate through the corresponding mounting holes of the limiting blocks from top to bottom to finish assembly; after assembly, the flat plate part is positioned above the spring piece, and the adhesive tape hook part is positioned below the spring piece; the two sides of the adhesive tape along the length direction are respectively provided with a hook groove, and the hook parts of the adhesive tape are hooked into the corresponding hook grooves, so that the adhesive tape is installed on the spring plate through the plurality of limiting blocks.

In a preferred embodiment of the present invention, at least one anti-back tooth is disposed on the vertical portion to prevent the vertical portion from backing out of the stopper mounting hole.

In a preferred embodiment of the invention, two opposite surfaces of the vertical part parallel to the length direction of the spring piece are respectively provided with an anti-back tooth.

In a preferred embodiment of the present invention, a spring groove is provided on each of both sides of the adhesive tape in the longitudinal direction, and a pair of spring pieces are fitted in the corresponding spring grooves.

In a preferred embodiment of the present invention, a spring plate insertion groove is provided at a bottom of each spoiler, the spring plate insertion groove extending in a length direction of the spoiler, and the spring plate is inserted into the spring plate insertion groove such that the spoiler is fitted over the spring plate.

In a preferred embodiment of the present invention, the spoiler assembly further includes a pair of end heads, each end head has a spring plate end slot adapted to an end of the spring plate and a spoiler end slot adapted to an end of the spoiler, and the end of the spring plate and the end of the spoiler are respectively inserted into the spring plate end slot and the spoiler end slot.

By adopting the technical scheme, the spring leaf is a single spring leaf, the excellent characteristics of the boneless wiper and the boneless wiper are combined, the defects are overcome, and the novel boneless wiper structure is formed

The invention has the beneficial effects that: the whole lateral rigidity and the torsional rigidity of the scraping piece are greatly improved, the limiting blocks are more and uniformly distributed, the pressure distribution of the scraping piece is uniform, the scraping and brushing effect is optimized, the scraping and brushing effect on the car window is better, and the appearance of the scraping piece is attractive.

The boneless wiper blade is suitable for almost all glass curvatures in the current market, and solves the problem that the common boneless wiper blade is difficult to match under the conditions of large change of the glass curvatures and poor hydrophilic performance.
