Publication number: 20230187147Abstract: A keyswitch assembly includes a base, a pressable plate, a first magnetic acting member and a second magnetic acting member. An accommodating space is defined within the base, and an upper surface of the base is provided with a connecting portion. The pressable plate includes a pressing portion, an acting portion and a pivotal connection portion located between the pressing portion and the acting portion and pivotally connected to the connecting portion. The first magnetic acting member is disposed on the acting portion; the second magnetic acting member is disposed on the base corresponding to the first magnetic acting member. The keyswitch assembly is configured such that the first magnetic acting member and the second magnetic acting are attracted or repulsed each other by a magnetic force, so as to provide or change a pressing resistance of the pressing portion.Type: ApplicationFiled: August 24, 2022Publication date: June 15, 2023Inventors: Chih-Yao CHI, Ling-Hsi CHAO, Da-Shan HSU, Shao-Lun HSIAO, Yu-Chun HSIEH

Patent number: 11604518Abstract: A tactile-adjustable keyboard includes plural keyswitches, an adjustment frame and a hybrid operation button. The adjustment frame is disposed corresponding to the keyswitches to move and interfere at least one of the keyswitches. The hybrid operation button includes a tactile switch, a non-tactile knob disposed at least partially surrounding the tactile switch, and a lens disposed at least partially surrounding the non-tactile knob. The tactile switch includes a switch shaft and a switch bar. The switch shaft is disposed in rotatable connection with the adjustment frame to move the adjustment frame. The switch bar extends externally from the switch shaft. A tactile feedback of said one keyswitch changes in response to the rotation of the tactile switch, while a non-tactile signal is generated in response to the rotation of the non-tactile knob, and the lens is illuminated in response to the rotation of the tactile switch.Type: GrantFiled: November 9, 2021Date of Patent: March 14, 2023Assignee: DARFON ELECTRONICS CORP.Inventors: Chen Yang, Chih-Yao Chi, Shao Lun Hsiao, Chih-Hao Chen

Publication number: 20220083151Abstract: A keyboard includes a cover plate having a plurality of first keyholes, an adjustment mechanism disposed under the cover plate, and a plurality of keyswitches. The adjustment mechanism includes an adjustment frame and a plurality of adjustment portions. The adjustment frame includes a plurality of ribs defining a plurality of second keyholes corresponding to the plurality of first keyholes, respectively. Each of the adjustment portions is proximate to a corresponding one of the second keyholes. Each of the keyswitches includes a tactile feedback member and is located in corresponding first and second keyholes, so that the adjustment portion corresponds to the tactile feedback member of its corresponding keyswitch. The adjustment frame is movable relative to the cover plate, so that each of the adjustment portions drives a portion of the tactile feedback member to move, to change tactile feedback of the keyswitches.Type: ApplicationFiled: November 9, 2021Publication date: March 17, 2022Inventors: Chen YANG, CHIH-YAO CHI, Shao Lun HSIAO, Chih-Hao CHEN

Patent number: 10937610Abstract: A keyboard includes a plurality of keyswitch structures and an adjusting plate movably disposed under the keyswitch structures. Each of the keyswitch structures includes a tactile feedback member. The adjusting plate includes a plate body and a plurality of adjusting bars protruding from the plate body toward the keyswitch structures and respectively corresponding to the tactile feedback members of the keyswitch structures. When the adjusting plate moves relative to the keyswitch structures, the adjusting bars drive the tactile feedback members to change tactile feedback of the keyswitch structures.Type: GrantFiled: August 7, 2019Date of Patent: March 2, 2021Assignee: DARFON ELECTRONICS CORP.Inventors: Yung-Chih Wang, Chia-Hung Liu, Yu-Chun Hsieh, Chen Yang, Chih-Yao Chi

Patent number: 7714245Abstract: The invention discloses a keyswitch, which includes a keycap and a balance member. The keycap thereof defines a lower surface, which has at least one mounting portion. The balance member has an axle thereof defines a first end and a second end opposite to the first end. Additionally, the axle is folded with a first angle and elongated from the first end to form a first side, and folded with a second angle and elongated from the second end to form a second side. The axle is mounted in the at least one mounting portion. Particularly, the second angle is between 30° and 60°.Type: GrantFiled: May 8, 2008Date of Patent: May 11, 2010Assignee: Darfon Electronics Corp.Inventor: Chih-Yao Chi

Patent number: 7572996Abstract: The invention discloses a keyswitch, which includes a substrate, a plurality of switches, a keycap, and at least one support. The switches are fixed on the substrate. The keycap thereof defines a bottom surface, which has a plurality of protruding portions, each of which corresponds to one of the switches. In addition, the at least one support is used for supporting the keycap to move vertically relative to the substrate, and each of the at least one support corresponds to one of the switches. Particularly, when the keycap is pressed, the protruding portions and/or the at least one supporting portion can trigger at least one of the switches.Type: GrantFiled: May 8, 2008Date of Patent: August 11, 2009Assignee: Darfon Electronics Corp.Inventor: Chih-Yao Chi
