Automobile rear view window windscreen wiper device capable of assisting in water removal

Abstract

The invention relates to the related field of automobile electronic control, and discloses an automobile rear window windscreen wiper device capable of assisting in water removal. The automobile rearview window windscreen wiper device comprises a main body box; a windscreen wiper box is fixedly connected to the upper end surface of the main body box; a corrugated pipe cavity with an upward opening and positioned on the right side of the windscreen wiper box is arranged in the main body box; trigger rod cavities with upward openings are formed in the main body box in a front-and-back symmetrical mode with the corrugated pipe cavity as the center; and the rear end walls of the trigger rod cavities are provided with water valve magnetic block cavities in a communicating mode. According to the automobile rear view window windscreen wiper device, reciprocating motion of a piston realizes the air exhaust effect of a rainwater cavity, so that certain pressure difference exists between the rainwater cavity and the external world; and meanwhile, the left-right reciprocating rotation of a windscreen wiper rod is matched, so that the water absorption effect of the rainwater cavity is intermittently triggered at the end points of the two moving sides of the windscreen wiper rod, rainwater gathered on the two sides of the rear view window is continuously absorbed into the rainwater cavityon the premise that the normal reciprocating work of the windscreen wiper rod is not affected, and the definition of the rear view window is guaranteed.

Description

technical field [0001] The invention relates to the related field of automobile electronic control, in particular to an automobile rear window wiper device capable of assisting water removal. Background technique [0002] At present, in order to ensure a clear view of the rear window when driving in rainy days, most vehicles will install a rear window wiper at the rear of the car. As a result, more rainwater will accumulate on both sides, and since most of the rear windows of automobiles have a certain slope, it will take a certain time for the accumulated rainwater to flow down due to gravity, so it is easy to gather on both sides when the wiper reciprocates. The rainwater is brought back to the rear window again, thereby reducing the clarity of the rear window. Contents of the invention [0003] The object of the present invention is to provide an automobile rear window wiper device capable of assisting water removal, which can overcome the above-mentioned defects of th...
