The invention provides an energy-saving ultrasonic wave invisible automobile windshield wiper system which comprises an ultrasonic wave transmitting device and an ultrasonic wave receiving device which are arranged on the two sides of automobile windshield respectively. The ultrasonic wave transmitting device amplifies sinusoidal signals and then outputs the amplified sinusoidal signals to an ultrasonic wave transmitting transducer to drive the ultrasonic wave transmitting transducer to emit ultrasonic waves, and ultrasonic travelling waves are generated in the whole windshield. The ultrasonic wave receiving device receives the ultrasonic waves sent by the ultrasonic wave transmitting transducer, converts sound signals to electrical signals and consumes electric power through a power consumption device, or is connected with a power source of the ultrasonic wave transmitting device through a charging circuit, and an ultrasonic wave receiving transducer converts the sound signals to the electrical signals and then charges an automobile power source, that is, part of electric energy is recycled. The energy-saving ultrasonic wave invisible automobile windshield wiper system has the advantages of being simple in structure, convenient to operate, stable in performance, wide in cleaning range, capable of hiding the ultrasonic wave transmitting transducer and the ultrasonic wave receiving transducer into columns A on the two sides of an automobile and achieving the invisibility effect, free of blocking the sight of a driver and the like.
