Patent number: 11566355Abstract: A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes. The strand carriers shuttle on both braiding routes respectively and incessantly. Two intersection points are defined when the two braiding routes intersect. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the two intersection points during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has two crossing points, which increases the practicability of the rope.Type: GrantFiled: July 6, 2021Date of Patent: January 31, 2023Inventor: Ming-Cheng Chen

Publication number: 20230007893Abstract: A braiding apparatus includes a platform, a base plate, a core unit, a transmission unit, a track assembly, and strand carriers. The track assembly is divided into two braiding track groups each provided with transmission discs. The transmission discs of both braiding track groups are sequentially connected to define two braiding routes directed in different directions. The strand carriers shuttle on both braiding routes respectively and incessantly. Four intersections are defined when the two braiding routes meets. Accordingly, carrier strands fed by the strand carriers are wound around a core strand fed by the core unit while shuttling incessantly and are interwoven with each other while passing through the four intersections during the incessant shuttling motion, thereby wrapping a multi-convolutional braided layer around the core strand to complete a rope. Each convolution of the braided layer has four crossing points, which increases the practicability of the rope.Type: ApplicationFiled: July 6, 2021Publication date: January 12, 2023Inventor: MING-CHENG CHEN

Publication number: 20220404101Abstract: A heat dissipation net disposed on a base plate of a vapor chamber unit includes a base net portion and conduction units formed on the base net portion. Each conduction unit has a protruding area, a recessed area, and a curved section formed between the protruding area and the recessed area. When the heat dissipation net is disposed on the base plate, the existence of the recessed area and the curved section prevents the base net portion from being unduly pressed and stuck to the base plate to thereby improve a capillary action of the heat dissipation net. A space formed between each protruding area and the base plate facilitates the quick conduction of vaporized working fluid of the vapor chamber unit. Thus, the entire heat dissipation efficiency is increased.Type: ApplicationFiled: June 18, 2021Publication date: December 22, 2022Inventor: MING-CHENG CHEN

Patent number: 8251183Abstract: In an electricity generating device by applying vehicle weight, a rolling vehicle wheel is weighting down on a pressure receiver to actuate a driving mechanism having a restoring function. It is then able to provide a unidirectional rotating torque to drive a generating device to produce electrical power. The mechanical power transmission is performed by a transmission gear unit composed of a driving wheel and a follower wheel interconnected each other with a transmission means therebetween. When the vehicle weight is applied to the driving mechanism by pressing the vehicle wheel on the pressure receiver, the driving mechanism is forced to downwardly urge a ratchet wheel and a driving wheel to rotate that in turn causes the rotation of the follower wheel through the transmission means thereby driving the generating device to operate to produce electricity.Type: GrantFiled: September 3, 2008Date of Patent: August 28, 2012Inventor: Ming-Cheng Chen
