The invention relates to a supporting structure for supporting a keycap of a keyswitch, and more particularly, the invention relates to a novel scissor-type supporting structure, keyswitch, and keyboard using the supporting structure.
A keyboard is an essential device for operating a computer. Generally, the keyboard is constituted by a plurality of keyswitches. Each keyswitch includes a base, a keycap, a supporting structure, an elastic object, and a switch. The switch isconfigured on the base, and the keycap is configured on the base and connected to the base through the supporting structure. The elastic object is configured between the keycap and the base, and normally above the switch.
When the keycap is pressed by a user, it moves toward the base and oppresses the elastic object to make the elastic object to trigger the switch. When the keycap is no longer pressed, the restoring force of the elastic object pushes the keycapback to the original position, and the elastic object stops triggering the switch. Besides, the supporting structure can assist the keycap to move in a predetermined range to prevent the keycap from deviating caused by pressing.
One of the popular supporting structures is the scissor-type supporting structure including two supporting members pivotally connected to each other. Please refer to FIG. 1A and FIG. 1B. FIG. 1A is a schematic diagram illustrating thesupporting structure 1 in the prior art, and FIG. 1B is a schematic diagram illustrating the structure in the scope of the dotted line of the supporting structure 1 in FIG. 1A. The supporting structure 1 has two supporting member: the first supportingmember 11 and the second supporting member 13. One terminal of the first supporting member 11 includes a first pivotal part 112 connected to the base of the keyswitch (not shown in the figures), and another terminal the first supporting member 11includes two first connecting parts 114 and 115 connected to the keycap of the keyswitch (not shown in figures). One terminal of the second supporting member 13 includes two second pivotal parts 132 and 133 connected to the base of the keyswitch, andanother terminal of the second supporting member 13 includes a second connecting part 134 connected to the keycap of the keyswitch.
Besides, the first supporting member 11 has a first arm 111 with a shaft 1110, and the second supporting member 13 has a second arm 131 with a hole 1310. When the supporting structure 1 is assembled, the shaft 1110 of the first arm 111 isaligned and pivotally connected to the hole 1310 of the second arm 131. Accordingly, the first supporting member 11 and the second supporting member 13 can rotate relative the shaft 1110 and the hole 1310, and then support the keycap to moveperpendicularly to the base.

In this embodiment, the first shaft 2111 passes through the first opening 2313 and is rotatably contained in the first containing space 2311 by the first hook part 2310, so that the first supporting member 21 and the second supporting member 23are capable of rotating relative to the first shaft 2111. Besides, the second shaft 2131 passes the second opening 2330 and is rotatably contained in the second containing space by the second hook part, so that the first supporting member 21 and thesecond supporting member 23 are capable of rotating relative to the second shaft 2131. In practice, the first shaft 2111 and the second shaft are located on an axis, so the first supporting member 21 and the second member 23 can rotate relative to theline connecting the first shaft 2111 and the second shaft 2131.
It should be noted that the second opening can face the same as or different direction from that of the first opening 2131 in practice. For example, if the first opening 2313 faces the first direction, the second opening can face the firstdirection or the second direction opposite to the first direction. Therefore, the first shaft 2111 and the second shaft 2131 can pass through the first opening 2313 and the second opening along the same direction or along different directions to becontained in the first containing space 2311 and the second containing space.
Besides, as shown in FIG. 2B, in this embodiment, the second arm 231 forms a buffering space 2315 around the first hook part 2310. The buffering space 2315 is used for buffering for the elastic deformation of the first hook part 2310 when thefirst shaft 2111 passes the first opening 2313. Similarly, the fourth arm 233 can form a buffering space with the same effect around the second hook part 2330.
Please further refer to FIG. 2C. FIG. 2C is a schematic diagram illustrating another structure in the scope of the dotted line of the supporting structure 2 in FIG. 2A according to another embodiment of the invention. As shown in FIG. 2C, thesecond arm 231 of the supporting structure 2 forms a first hole 2317 corresponding to the first containing space 2311 of the first hook part 2310. Therefore, when the first shaft 2111 is rotatably contained in the first containing space 2311 of thefirst hook part 2310, a part of the first shaft 2111 is contained in the first hole 2317. In practice, the fourth arm 233 of the supporting structure 2 can form a second hole corresponding to the second containing space of the second hook part 2330. Therefore, when the second shaft 2131 is rotatably contained in the second containing space of the second hook part 2330, a part of the second shaft 2131 is contained in the second hole. Accordingly, the first supporting member 21 can be pivotallyconnected to the second supporting member 23 more strongly to prevent the first shaft 2111 from dropping from the first containing space 2311 or to prevent the second shaft 2131 from dropping from the second containing space.
Besides, as shown in FIG. 2C, the second arm 231 can further form a first groove 2319 near the first hole 2317. The first groove 2319 can guide the first shaft 2111 to pass through the first opening 2313 to be contained in the first containingspace 2311 and the first hole 2317. Similarly, the fourth arm 233 of the supporting structure 2 of the invention can further form a second groove near the second hole in practice. The second groove can guide the second shaft 2131 to pass through thesecond opening to be contained in the second containing space and the second hole. Through the configuration of the first groove 2319 and the second groove, the supporting structure 2 of the invention could be assembled easily.
