The invention discloses an electric vehicle overspeed limiting device for students, which comprises a rear frame and a wheel axle, a sound production cavity is arranged in the rear frame, a pluralityof reeds are fixed on the inner wall of the sound production cavity at equal intervals in the circumferential direction, and a plurality of impact balls are fixed on the outer wall of the wheel axle in the sound production cavity. A device groove communicated with the sounding cavity is formed in the rear frame, a horizontally-arranged tuning fork is installed at the bottom in the device groove, aglass rod and a rubber rod are fixed to the two tail ends of the tuning fork through insulating pads respectively, silk cloth and a fur pad are fixed to the inner wall of the device groove, the silkcloth makes contact with the glass rod, The fur pad is in contact with the rubber rod, a liquid storage cavity is formed in the inner side of the sound production cavity, the liquid storage cavity isfilled with electrorheological fluid, and a positive plate and a negative plate are fixed to the opposite inner walls of the liquid storage cavity respectively. The device is reasonable in structure,can apply resistance when students drive the electric vehicle overspeed, reduces the vehicle speed, and reduces the occurrence of accidents.
