Patent number: 11941190Abstract: A full-area touch device includes a base plate of a support unit. Multiple resilient sheet sets are connected to the base plate. An adjusting unit is mounted to the supporting unit, and includes a limiting member and an adjusting member. The adjusting member is disposed under and abuts against the limiting member such that a top end of the limiting member is disposed above the base plate, and is movable to adjust a distance between the top end of the limiting member and the base plate. A touch control unit is mounted to the resilient sheet sets, includes a tact switch that is disposed above and aligned with the limiting member, and is downwardly movable relative to the supporting unit against a resilient force of the resilient sheet sets for contacting the limiting member.Type: GrantFiled: May 11, 2023Date of Patent: March 26, 2024Assignee: Sunrex Technology Corp.Inventors: Yin Chu, Chih-Po Ku

Patent number: 11908639Abstract: A character key device includes a bottom plate, a backlight module, a film module, a support module and a key cap. The backlight module includes a metal plate, an insulating layer, a backlight circuit and a light emitter. The metal plate includes a metal plate body, and a plurality of pivot seats extending upwardly from the metal plate body. The film module is disposed on the backlight circuit. The film module defines at least one accommodating space adjacent to the backlight circuit and allowing the at least one light emitter to extend therein. The film module is pressable to generate a trigger signal. The support module includes a support disposed on the film module and connected to the pivot seats of the metal plate, and an elastomer disposed on the film module. The key cap is disposed on the support module.Type: GrantFiled: January 4, 2023Date of Patent: February 20, 2024Assignee: Sunrex Technology Corp.Inventor: Chih-Po Ku

Patent number: 11726600Abstract: A full-area touch device including a supporting unit, a touch control unit and a plurality of limiting units. The supporting unit includes a base plate. The touch control unit is movable relative to the supporting unit between an unpressed original position and a pressed position. The limiting units are for limiting height position and travel distance of the touch control unit. Each of the limiting units includes a blocking portion disposed on the base plate, and a limiting portion disposed on a corresponding one of two support resilient sheet sets of the supporting unit. The limiting portions of the limiting units extend in a first axial direction or a second axial direction to be limited by the blocking portions of the limiting units.Type: GrantFiled: October 28, 2022Date of Patent: August 15, 2023Assignee: Sunrex Technology Corp.Inventors: Yin Chu, Chih-Po Ku
