Patents by Inventor Zhanqi ZHANG

Zhanqi ZHANG has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Motor
    Patent number: 11025139
    Abstract: A motor includes a stator, a rotor rotatable relative to the stator, a circuit board fixed to the stator, and a heat sink disposed on the circuit board, a side surface of the circuit board facing the heat sink has an insulating region and a metal heat dissipation region without solder mask. The thermal resistance between the circuit board and the heat sink can be reduced by the metal heat dissipation region, thereby improving the heat dissipation of the circuit board.

  • PRINTED CIRCUIT BOARD AND MOTOR INCLUDING THE SAME
    Publication number: 20200128671
    Abstract: A printed circuit board includes a substrate and an inductor, a first through hole defined in the substrate, the inductor including a magnetic core with a middle leg, the middle leg passes through the first through hole, and a conductive trace on at least one conductive layer of the printed circuit board spirally surrounds the first through hole to form conductive coil of the inductor. The present disclosure also provides a motor including a stator, a rotor, and the above described printed circuit board. The inductor is integrated with the printed circuit board, which reduces the size of the board and the motor and reduces material cost and power consumption.

  • MOTOR, PRINTED CIRCUIT BOARD, AND ENGINE COOLING FAN MODULE INCLUDING THE MOTOR
    Publication number: 20200100393
    Abstract: A printed circuit board includes a substrate and at least one heat generating electronic component mounted on the substrate. At least one ceramic heat conducting member is embedded into the printed circuit board at positions corresponding to the at least one heat generating electronic component. Side surfaces of the ceramic heat conducting member in contact with the printed circuit board are rough surfaces. Heat dissipation effect of the motor is improved.
