The present invention proposes a non-slideway driving device for a translational window scraper, which includes a frame, a motor seat, a reduction motor, a
crank, a connecting rod, a rocker, a lower push-pull rod, an upper push-pull rod, a main short rod, a main long rod, a short rod, a long rod, an auxiliary long rod, a short connecting rod, a short horizontal connecting rod, a long connecting rod, an auxiliary long connecting rod, a translation seat and their connection relationship. A
crank rocker mechanism, a pair of upper and lower push-pull rod groups and three
parallelogram series-parallel mechanisms are adopted, so that the translation seat can perform reciprocating
translational motion without a slideway, and then the scraper can be translated to scrape the window, replacing the traditional fixed-point swing
crank rocker mechanism driving device and the slideway reciprocating translational
sprocket mechanism driving device, which can simultaneously meet the high technical requirements that the window glass has no
blind spot scraper and all the moving mechanisms of the driving device can be fully sealed to prevent
water seepage, dust, salt spray and wear, and has the unique characteristics of adapting to the window glass scraper and high reliability and long service life performance.
