雨刮器连杆结构、雨刮器总成及轨道交通车辆
By designing the wiper linkage structure and utilizing the cooperation of the sliding component and the transmission rod, full-coverage wiping of the windshield of rail transit vehicles is achieved. This solves the problem that the brush blade cannot contact the upper and lower adhesive seams, increases the wiping area, and moves the stop position of the brush arm outward to ensure that visibility is not affected.

AI Technical Summary
The windshields of rail transit vehicles are relatively wide, and the wiper blades cannot reach the upper and lower adhesive seams of the windshield when wiping, resulting in the wiping area only covering the middle area, which affects the driver's view.
The wiper arm adopts a linkage structure, including two parallel brush arms, a first linkage, a transmission rod, and a second linkage. Through the cooperation of the sliding component and the transmission rod, the dynamic reciprocating motion of the brush blade is realized, which increases the wiping area and moves the stop position of the brush arm outward.
Dynamic scraping was achieved, increasing the scraping area. The stop position of the brush arm was moved further outward, so as not to affect the driver's cab's view, thus solving the problem of incomplete scraping in the existing technology.
