Publication number: 20240160253Abstract: A hinge and a mobile terminal to resolve poor use effect of a foldable electronic device. The hinge includes a main body, and a first folding assembly and a second folding assembly that are symmetrically disposed along the main body. When the first folding assembly and the second folding assembly are rotated toward each other, a length of the hinge can be extended, and an accommodation space for accommodating the flexible display can be formed. When the first folding assembly and the second folding assembly are rotated away from each other, the length of the hinge can be reduced, and a support surface for supporting the flexible display can be formed, so that the flexible display cannot be stretched, compressed, or the like during folding and unfolding, thereby improving the use effect and safety of the mobile terminal.Type: ApplicationFiled: January 23, 2024Publication date: May 16, 2024Inventors: Changliang LIAO, Weifeng WU, Li LIAO, Kenji NAGAI, Ding ZHONG, Qiao DENG

Publication number: 20220303371Abstract: This application provides a rotation shaft structure and an electronic device. The rotation shaft structure includes a main shaft assembly, and two folding assemblies. The folding assembly includes a rotation assembly, a support plate, and a housing mounting bracket. The rotation assembly is rotationally connected to the main shaft assembly. The support plate is rotationally connected to the housing mounting bracket and slidably connected to the rotation assembly. When two housing mounting brackets rotate toward each other, two support plates rotate in a same direction relative to the housing mounting brackets on corresponding sides, so that the two support plates and the main shaft assembly can form a triangle-like display accommodation space. When the electronic device is in a closed state, the display accommodation space can be used for accommodating a bent portion of the flexible display, so that the flexible display is not damaged by extrusion.Type: ApplicationFiled: June 10, 2022Publication date: September 22, 2022Inventors: Changliang LIAO, Weifeng WU, Li LIAO, Kenji NAGAI, Ding ZHONG, Qiao DENG, Tao HUANG, Qiang ZHAN, Haiqiang TIAN, Yuehua HU, Feng ZHAO, Gang WANG, Bo HUANG, Zhixiao XU, Shangyun WANG

Publication number: 20130164652Abstract: Novel proton exchange membrane fuel cells and direct methanol fuel cells with nanostructured components are configured with higher precious metal utilization rate at the electrodes, higher power density, and lower cost. To form a catalyst, platinum or platinum-ruthenium nanoparticles are deposited onto carbon-based materials, for example, single-walled, dual-walled, multi-walled and cup-stacked carbon nanotubes. The deposition process includes an ethylene glycol reduction method. Aligned arrays of these carbon nanomaterials are prepared by filtering the nanomaterials with ethanol. A membrane electrode assembly is formed by sandwiching the catalyst between a proton exchange membrane and a diffusion layer that form a first electrode. The second electrode may be formed using a conventional catalyst. The several layers of the MEA are hot pressed to form an integrated unit.Type: ApplicationFiled: May 23, 2012Publication date: June 27, 2013Applicant: The Regents of the University of CaliforniaInventors: Yushan Yan, Xin Wang, Wenzhen Li, Mahesh Waje, Zhongwei Chen, William Goddard, Wei-Qiao Deng
