Publication number: 20240139990Abstract: An internal rotor type nail drive device of electric nail gun, comprising a nailing rod and an internal rotor type rotary actuator that can output a specific rotation angle and can drive the nailing rod to move downward for nailing. Specifically, the rotary actuator comprises a stator and a rotor arranged inside the stator, even groups of electromagnetic mutual action components are configured in pairs between the stator and the rotor, to generate a tangential force to drive the rotor to rotate for a specific rotation angle, and to drive the nailing rod to move for a nailing stroke. The nailing stroke can be determined by a specific rotation angle. Thus, through the above configuration of the rotary actuator, the structure of the electric nail gun can be simplified, and the kinetic energy for nailing can be increased.Type: ApplicationFiled: August 22, 2023Publication date: May 2, 2024Inventors: I-TSUNG WU, CHIA-SHENG LIANG, YU-CHE LIN, WEN-CHIN CHEN

Patent number: 8820692Abstract: A motor casing includes a frame assembly and a motor base. The frame assembly includes a frame having an inner face defining an air channel, and a plurality of connection members disposed in the air channel. Each connection member has first and second ends. The first ends of the connection members are coupled to the inner face of the frame. The motor base includes a supporting member and a covering member. The supporting member has an inner surface defining a through-hole, and an outer surface coupled with the second ends of the connection members. An opening portion and a coupling portion are formed at two sides of the through-hole. The covering member is coupled to the opening portion of the supporting member and has first and second surfaces. The first surface faces the through-hole of the supporting member. The covering member includes at least one vent.Type: GrantFiled: March 13, 2012Date of Patent: September 2, 2014Assignee: Sunonwealth Electric Machine Industry Co., Ltd.Inventors: Alex Horng, Chia-Chin Wu, Shou-Chien Chang, Hung-Jen Chuan

Patent number: 8514560Abstract: A rotate-to-retract type storing apparatus including a U-shaped protective casing, a shell body and a storing arrangement. A disk member is protrudes adjacent to an open side at the surface of protecting casing, and a protrusion member is provided at a partial position of the disk member. The shell body defines a receiving cavity and includes an insertion hole at a front end thereof for a second end portion of the storing arrangement to get into the receiving cavity and a retention hole penetrating a bottom surface of the shell body for coupling with the disk member so that the shell body is capable of rotating with respect to the protective casing and directing the coupling slot to rotate with respect to the protrusion member. This defines a moving distance—just enough for a first end portion of the storing arrangement to move between an application position and a retraction position. The result is a minimized size of the storing apparatus.Type: GrantFiled: December 22, 2010Date of Patent: August 20, 2013Assignee: Dong Wei Industry Limited CompanyInventor: Chia Chin Wu

Publication number: 20110260032Abstract: A motor base comprises a supporting member and an enclosure member. The supporting member has an outer surface and an inner surface, wherein the inner surface defines a through-hole. One side of the through-hole forms an opening portion and another side of the through-hole forms a coupling portion. The enclosure member is coupled to the opening portion of the supporting member and has a first surface and a second surface opposing to the first surface. The first surface faces the through-hole of the supporting member. The enclosure member further comprises at least one vent extending from the first surface to the second surface thereof.Type: ApplicationFiled: April 23, 2010Publication date: October 27, 2011Inventors: Alex Horng, Chia-Chin Wu, Shou-Chien Chang, Hung-Jen Chuan

Publication number: 20100315004Abstract: A lamp includes a lighting module having a lighting element and a control circuit electrically connected to the lighting element. The lamp further includes a control unit having a temperature sensor and a processor electrically connected to the temperature sensor and the control circuit. The temperature sensor senses a temperature of the lighting element and generates a temperature sensing result. The processor controls brightness of the lighting element based on the temperature sensing result of the temperature sensor. Since the brightness of the lighting element can be controlled by the processor through the control circuit using the temperature sensing result, overheating of the lighting element during operation can be avoided. The service life of the lighting element is, thus, prolonged.Type: ApplicationFiled: June 11, 2009Publication date: December 16, 2010Inventors: Alex Horng, Chi-Hung Kuo, Chia-Chin Wu
