Qingliang LANG 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.
    Type: Grant

  • Integrated electrical pump and oil pressure control method thereof
    Patent number: 10530286
    Abstract: An integrated electrical pump comprises a motor, an oil pump driven by the motor, and a pressure control system. The pressure control system controls a hydraulic pressure of the oil pump according to a motor speed of the motor, an oil temperature and a pressure command. An oil pressure control method of the integrated electrical pump is also provided.
