The invention discloses a pneumatic device for cleaning an automobile window and exchanging air in an automobile. The pneumatic device comprises a machine body, the machine body is a transmission device which is arranged in the automobile and can utilize wind energy, a first fan cavity is formed in the machine body, the pneumatic device is provided with a wind energy transmission device, and the position of a sliding push plate can be changed through centrifugal rotation of a push block; therefore, the meshing center distance between a left variable-speed belt wheel, a right variable-speed belt wheel, a driven variable-speed belt wheel and a stepless variable-speed belt is changed, namely, the transmission ratio is changed, so that a driven shaft keeps a certain unchanged rotating speed under different rotating speeds of a power fan, and a windshield wiper can clean front side glass at a constant speed; therefore, the optimal cleaning effect is achieved, and the sight condition of a driver is not influenced; and air in the automobile can be purified to a certain degree through rotation of the power fan, the purification speed cannot be changed at will according to the running speed, and therefore the automobile cannot feel uncomfortable when running on rainy days.
本发明公开了一种用于汽车车窗清洗和车内换气的风动装置,包括机身,机身是汽车内部设置的一种能够对风能利用的传动装置,机身内设有风扇腔一,本装置设有风能传动装置,能够通过推动块的离心转动改变滑动推板位置,从而改变左变速带轮、右变速带轮和从动变速带轮与无级变速带之间啮合的中心距,即改变传动比,使动力风扇在不同的转动速度下,从动轴保持一定不改变的转动速度,从而使雨刷能够对前侧玻璃进行恒定的清洗速度,从而达到最佳的清洗效果,且不影响行驶人的视线状况;且能够通过动力风扇转动对车内的空气进行一定的净化,且净化速度不会根据行驶速度进行任意改变,从而使车能在雨天行驶时不会产生不适。
