The utility model relates to the technical field of liquid cooling loops of internal
combustion engines of fuel vehicles, in particular to an electronic water pump structure which comprises a rubber support, a shell, a
stator winding, an
impeller rotor and a sealing
assembly, and the sealing
assembly comprises a waterproof sleeve, a waterproof sleeve sealing ring, a
front cover sealing ring, a rear cover sealing ring, a protection component and a control component. The waterproof sleeve sealing ring, the
front cover sealing ring, the rear cover sealing ring, the protection component and the control component are installed in the shell, the
stator winding is installed in the shell, the
impeller rotor is located at the front end of the
stator winding, and the rear cover sealing ring is located at the rear end of the stator winding. The waterproof sleeve is located between the stator winding and the
impeller rotor to play a waterproof role, and the sealing performance is improved through the
front cover sealing ring and the waterproof sleeve sealing ring, so that in the using process of the water pump, liquid cannot enter the shell due to poor sealing performance, and a motor is protected against damage.
