Patent number: 9683617Abstract: A self-locking mechanism has a driving member, a driven member, a stationary member, a lock holder and a number of lock elements. The lock holder encircles the driving member and the driven member. The lock holder has a support base and ribs extending from the support base. A lock element is coupled to the axial end portion of each rib. The lock elements are radially positioned between a radially outer surface of the driven member and the inner wall of the stationary member. The distance between the radially outer surface and the inner wall gradually decreases from a center to opposite circumferential sides. The maximum distance between the radially outer surface and the inner wall is greater than the diameter of the lock element, and the minimum distance is less than the diameter of the lock element.Type: GrantFiled: December 30, 2015Date of Patent: June 20, 2017Assignee: JOHNSON ELECTRIC S.A.Inventors: Yuan Chun Zhang, Fa Yun Qi, Jin An Nie, Rui Feng Qin

Publication number: 20160223040Abstract: An actuator for an electric parking brake system includes a motor, an output member, and a speed reduction device. The speed reduction device includes a transmission mechanism and a self-locking mechanism. The self-locking mechanism includes a fixed member, first and second rotating bodies, and a spring. The second rotating body transmits torque to the output member via a planetary gear mechanism. The spring prevents the brake from driving the motor.Type: ApplicationFiled: January 29, 2016Publication date: August 4, 2016Inventors: Michael WATZEK, Yuan Chun ZHANG, Jin An NIE, Fa Yun QI, Ya Jie CHEN, Rui Feng QIN, Michael KAESER

Publication number: 20160190757Abstract: A brush for an electric motor has a brush body having a front end surface configured to make sliding electrical contact with a commutator of the motor. First and second side surfaces are connected to the front end surface. The first side surface and the second side surface are positioned on opposite sides of the brush body in a rotational direction of the commutator. The front end surface has a first contact surface and a second contact surface that contact the commutator earlier than other regions of the front end surface, and are respectively positioned on diametrically opposed corners of the front end surface. In an initial state, the width of the contact area between the brush and the commutator is increased to extend the commutation time.Type: ApplicationFiled: December 21, 2015Publication date: June 30, 2016Inventors: Fa Yun QI, Shu Dan ZHAO, Cheng Shun DU, Rui Feng QIN

Publication number: 20150335661Abstract: The present invention refers to a medicament which activates gastrointestinal movement. The medicament consists essentially of Cucurbitacin D and one or more substances form the group including Cucurbitacin A, Cucurbitacin B, Cucurbitacin E, Isocucurbitacin B and Isocucurbitacin D. The medicament is made from an extract obtained from Muskmelon Base, the fruit stem of Cucumis melo L. The medicament can promote enterokinesia in both normal animals and in animal models where gastrointestinal movement is inhibited. It has also been demonstrated to activate the movements of the stomach, small and large intestines. The extract may be used alone or in combination with the other botanical ingredients or chemical substances to form the pharmaceutical preparation.Type: ApplicationFiled: June 10, 2015Publication date: November 26, 2015Inventors: Chen Xie, Xiuzhen Luo, Yun Qi
