Patent number: 10008345Abstract: A keyswitch includes a board having a first magnetic portion and a pivot portion, a cap, a switch, and a support device including a first support member having first and second bodies connected to each other via an elastic connection arm. The first body has first and second end portions connected to the cap and the pivot portion respectively. The second body has a second magnetic portion and a triggering portion. A U-shaped slot is formed around the triggering portion to make the triggering portion form an elastic cantilever arm extending from the second body. When the cap is pressed to make the second magnetic portion away from the first magnetic portion at a specific distance, the triggering portion triggers the switch. When the cap is released, a magnetic force between the first and second magnetic portions drives the second magnetic portion to approach the first magnetic portion.Type: GrantFiled: March 20, 2017Date of Patent: June 26, 2018Assignees: DARFON ELECTRONICS (SUZHOU) CO., LTD., DARFON ELECTRONICS CORP.Inventor: Chien-Shih Hsu

Patent number: 9984840Abstract: A keyswitch structure includes a base, a keycap, a frame disposed between the base and the keycap for providing a supporting and moving mechanism to the keycap, and another frame interacting with the former frame through a magnetic attraction force. When the keycap is not pressed, the magnetic attraction force drives the two frames to stably stand on the base and form a stable supporting structure, so that the keycap is located at a farther position relative to the base. When the keycap is pressed with an external force to move toward the base, the magnetic attraction force is overcome so that the two frames depart from each other; that is, the above stable supporting structure is temporarily destroyed. Once the external force applied to the keycap is eliminated, the two frames will form the stable supporting structure again due to the magnetic attraction force.Type: GrantFiled: December 18, 2016Date of Patent: May 29, 2018Assignees: DARFON ELECTRONICS (SUZHOU) CO., LTD., DARFON ELECTRONICS CORP.Inventor: Chien-Shih Hsu

Patent number: 9508505Abstract: A keyswitch structure includes a bottom plate, a keycap, a first support, a second support, and a magnetic member. The bottom plate has a magnetic portion. The keycap is disposed above the bottom plate. The first support and the second support are disposed between the bottom plate and the keycap. The keycap is capable of moving up and down relative to the bottom plate through the first support and the second support. The magnetic member is disposed between the bottom plate and the keycap corresponding to the magnetic portion. The magnetic member and the magnetic portion induce an attractive force therebetween. The attractive force makes the magnetic member contact and apply force to the first support and the second support so that the first support and the second support tend to move the keycap away from the bottom plate.Type: GrantFiled: May 12, 2015Date of Patent: November 29, 2016Assignee: DARFON ELECTRONICS CORP.Inventor: Chien-Shih Hsu

Patent number: 9412535Abstract: A keyswitch structure includes a base, a keycap, a lift mechanism, and a magnetic member. The keycap is capable of moving up and down relative to the base through the lift mechanism. The lift mechanism includes a support that has a side edge portion, abutting against the base through a sharp edge, and a magnetic portion at the side edge portion. The magnetic portion extends outward from the side edge portion. The support is movably connected to the keycap through another side edge portion of the support. The magnetic member is disposed on the base corresponding to the magnetic portion. The magnetic portion and the magnetic member produce a magnetic attraction force therebetween. When an external force applied to the keycap is eliminated, the magnetic attraction force drives the support to rotate about the sharp edge relative to the base, so that the keycap moves away from the base.Type: GrantFiled: August 5, 2015Date of Patent: August 9, 2016Assignee: DARFON ELECTRONICS CORP.Inventor: Chien-Shih Hsu

Patent number: 9378903Abstract: A keyswitch structure includes a base plate, a keycap, a lift mechanism, and a balance link. The lift mechanism connects between the keycap and the base plate such that the keycap can move up and down relative to the base plate. The balance link is formed substantially in a U-shaped profile. The middle portion thereof is rotatably disposed on the base plate; the two ends thereof are respectively formed in an L-shaped profile and rotatably inserted into two slot structures on the keycap or the lift mechanism or both. Compared with a conventional balance link formed in an n-shaped profile connecting a keycap and a base plate, the invention provides more diverse structural connections, conducive to structural miniaturization. Furthermore, a support of the lift mechanism includes a protrusion capable of being blocked by a limitation structure disposed on the base plate for controlling the rotation angle of the support.Type: GrantFiled: December 16, 2013Date of Patent: June 28, 2016Assignees: DARFON ELECTRONICS (SUZHOU) CO., LTD., DARFON ELECTRONICS CORP.Inventor: Chien-Shih Hsu
