The invention discloses a micro-nano motor structure propelled based on bubble collapse high-speed jet, and belongs to the technical field of micro-nano motors. The structure comprises a chemical fuel1, a working medium channel 2, a bubble discharge cavity 3, bubbles 4, an ultrasonic system 8, goods to be transported 9 and a motor outer shell 10; the goods to be transported 9 are mounted in the motor outer shell 10, and the chemical fuel 1 is filled in gaps; the bubbles 4 are positioned in the bubble discharge cavity 3; the bubble discharge cavity 3 is at the tail end of the chemical fuel 1;and the ultrasonic system 8 is positioned at the external of the motor outer shell 10. The chemical fuel 1 is reacted to generate the bubbles 4; when the bubbles 4 are deviated from the motor of the micro-nano motor, the ultrasonic system 8 generates ultrasonic waves to control collapse of the bubbles 4; and the bubbles are collapsed to generate micro jet and pressure waves to impact on the tail wall surface of the micro-nano motor, so that the micro-nano motor is driven to quickly move forwards. The structure is propelled through the micro jet and the pressure waves, so that the micro-nano motor can achieve a higher motion speed.
