Windshield wiper structure for vehicles

Abstract

A windshield wiper structure for vehicles, comprises a truss saddle, a bow elastic stripe, a cover body, some detachable clamping devices, a strip scraper and a frame cover; wherein, some hollow pressure adjusting vents are created on said bow elastic stripe in order to keep nearly same elasticity at every sections of said bow elastic stripe. Hence, it can equilibrate force in every portions of whole wiper such that achieving in adjust-effect of even pressure distribution. Then, the contact between said strip scraper and the windshield glass is holistically even tight uniformly and hermetic closely to enhance the scraping effect of windshield wiper as well as the effect of prolonging service-lifetime with reducing expense in association with decreasing of replacing new product frequency in consequence of such even pressure distribution. Thus, it has more effect in economy and environmental protection.

Description

FIELD OF THE INVENTION [0001] The present invention relates to a windshield wiper structure for vehicles, More particularly the contact between the scraper of windshield wiper and the windshield glass is holistically even tight uniformly and hermetic closely to enhance the scraping effect of windshield wiper as well as the effect of no noise in scraping action. And it can simplify the assembly process and reduce the process time in production due to simple structure and fewer parts so that decreasing the waste in wearing and damage of trivial parts. Hence, it has much more effects in economy and environment protection. BACKGROUND OF THE INVENTION [0002] Referring to FIG. 1 to FIG. 3, the structure of the conventional first kind and second kind of windshield wiper comprises a master wiper 2, in which having a first holding arm 4 being jointed with each articulation 3 on both ends respectively. And, a second holding arm 6 is jointed on the articulation 5 of each inwards end of said bo...

AI Technical Summary

Benefits of technology

[0025] The primary objective of the present invention is to provide a windshield wiper structure for vehicles, which comprises a truss saddle, a bow elastic stripe, a cover body, some detachable clamping devices, a strip scraper and a frame cover; wherein, some hollow pressure adjusting vents are created on said bow elastic stripe in order to keep nearly same elasticity at every sections of said bow elastic stripe. Hence, it can equilibrate force in every portions of whole wiper such that achieving in adjust-effect of even pressure distribution. Thus, the contact between said strip scraper and the windshield glass is holistically even tight uniformly and hermetic closely to enhance the scraping effect of windshield wiper as well as the effect of prolonging service-lifetime with reducing expense in association with decreasing of replacing new product frequency in consequence of such even pressure distribution.

[0026] Another object of the present invention is to provide a windshield wiper structure for vehicles, wherein, said cover body is unitary-molded such that freeing from directionality as sleeve it with said bow elastic stripe up to completely matched. Hence, it substantially simplifies assembly process and decreases man-hour in production. Moreover, a pair of weather-stripping fasciae are contrived at bottom section of said cover body to prevent all detachable clamping devices from being battered by the wind and the rain as well as weathering such that prolonging its service-lifetime in consequence of promoting erosion-resistant capability.

[0027] The other object of the present invention is to provide a windshield wiper structure for vehicles, wherein, all said detachable clamping devices are directly riveted on said bow elastic stripe without any extra bracing design such that simplifying the structure of said cover body. Thus, total production cost can be substantially decreased in consequence of simplifying the production process.

Problems solved by technology

And, the discarded old products become garbage and pollute the environment.

It can be easily fallen off unexpectedly in consequence of being deformed in aforementioned motion.

Therefore, it not only causes extra expense in extruding process of mold but also increases the difficulty in production process, which also relatively resulting in elevation of production cost.

Hence, it causes the increase of damage rate in consequence of bad erosion-resistant capability.

Thus, its service lifetime is indirectly decreased and resulting in drawback of need to replace it early.
