Patent number: 11450492Abstract: A key structure includes a switch circuit layer, a pedestal and a keycap. The pedestal includes a protrusion part and a hollow part. The keycap includes a buffering hook and a locking hook. The pedestal is disposed on the switch circuit layer. The keycap is disposed within the hollow part of the pedestal. The buffering hook and the locking hook of the keycap are aligned with the protrusion part of the pedestal. While the keycap is moved in a direction away from the switch circuit layer, the buffering hook is contacted with the protrusion part and then the locking hook is contacted with the protrusion part.Type: GrantFiled: September 23, 2021Date of Patent: September 20, 2022Assignee: PRIMAX ELECTRONICS LTD.Inventors: Xiao-Jun Chu, Li-Qiang Chen

Patent number: 11094479Abstract: A key structure includes a keycap, a pedestal and an elastic element. The keycap includes a main body and a coupling shaft. The pedestal includes a key slot. The key slot has an upper part and a lower part. The coupling shaft is penetrated through the upper part of the key slot and movable within the key slot upwardly or downwardly. The elastic element is installed in the lower part of the key slot. After an external force applied to the keycap is released, the elastic element is elastically restored, so that the keycap is returned to an original position. At the same time, the buffering elements in the key slot interfere with the coupling shaft. Consequently, an ascending speed of the keycap is reduced, and a click sound generated from the collision between keycap and the pedestal is reduced.Type: GrantFiled: May 28, 2020Date of Patent: August 17, 2021Assignee: PRIMAX ELECTRONICS LTD.Inventors: Xiao-Jun Chu, Li-Qiang Chen, Liu-Bing Cai, Sheng-An Tsai, Chun-Che Wu
