Problems solved by technology

[0004] This X supporting structure device has realized thin profile namely low height and good hand feel consistency, but because the outer frame central hole 5 on the outer frame connecting rod 6 is perpendicular to the drawing direction, the mold structure is complicated (one outer frame connecting rod 6 must Set a left-right symmetrical side core-pulling structure), in the production process, in order to improve efficiency, one mold is often used to produce multiple parts at a time, and multiple small-sized (6mmX10mm) outer frame connecting rods 6 must be designed in one pair of molds. On the one hand It will lead to a complex mold structure and a sharp rise in costs. On the other hand, the addition of multiple sets of small-sized side core-pulling moving parts will seriously affect the service life of the mold
At the same time, the center hole 5 of the outer frame in the form of a through hole is opened on the two arms of the outer frame connecting rod 6, which weakens the strength and rigidity of the outer frame connecting rod 6 (the outer frame central hole 5 with a diameter of ¢0.8mm is opened at a width of only 1.3mm. On the two arms of the outer frame connecting rod 6), the diameter of the inner frame pivot 2 on the inner frame connecting rod 3 is usually designed as a small cylinder with a diameter of ¢0.8mm. The strength and rigidity of this small cylinder are also poor. When the keycap moves up and down relative to the su

Example Embodiment

[0032] Example 1

[0033] See image 3 , Figure 4 The X support structure device of the present invention consists of a keycap 14 with a keycap rotating part 15 and a keycap sliding part 16, a rubber elastic ring 17, a support plate 9 with a rotating part 8 and a sliding part 10, a membrane switch sheet 11, and a bottom plate 12. And under the key cap 14, the inner frame connecting rod 3 and the outer frame connecting rod 6 rotate and cooperate with the X bracket in the middle.

[0034] See Figure 4 , The inner frame pivot 2 on the inner frame connecting rod 3 is hinged with the outer frame pivot hole 5 on the outer frame connecting rod 6, the lower hinge shaft 13 of the outer frame and the lower shaft 4 of the inner frame are respectively connected to the rotating part 8 on the support plate 9 The sliding part 10 is in a rotation fit and a sliding fit. The upper hinge shaft 1 of the inner frame and the upper sliding shaft 7 of the outer frame respectively form a rotation and sl...

[0045] Example 2

[0046] See Figure 14 , Figure 15 , Figure 16 , Figure 17 , The sliding center shaft 28 is located near the upper middle of the arms of the inner frame link 3, the pivoting shaft 31 is located obliquely below the sliding center shaft 28, the pivot slot 26 is located near the lower center of the arms of the outer frame link 6, the pivot slot 26 The opening is downward, and the central sliding groove 19 opens upward and is located near the upper middle of the arms of the outer frame link 6.

[0047] When the keycap 14 is pressed, the keycap 14 pushes the rubber elastic ring 17 to elastically deform and move downward, and the sliding center shaft matching portion 29 on the sliding center shaft 28 slides down along the sliding circular surface 20 of the center groove, sliding The central shaft fitting portion 29 slides along the central groove circular surface 20 to restrict the pivot shaft fitting surface 30 from rotating on the central groove circular arc surfac...

Abstract

The invention discloses an X-shaped support structure device, which comprises a rubber elastic ring 17, a membrane switch sheet 11 and an inner frame connecting rod 3, wherein the upper end and the lower end of an outer frame connecting rod 6 are connected with the membrane switch sheet 11, a keycap 14 and a support plate 9. The device is characterized in that: a sliding middle shaft fitting part 29 on a sliding middle shaft 28 which is positioned on a connecting rod and a rotating pivot shaft fitting surface 30 on a rotating pivot shaft 31 are in sliding fit with a pivot groove sliding circular surface 20 on another connecting rod and in running fit with a pivot groove arc surface 25; and the pivot groove sliding circular surface 20 shares a circle center with the pivot groove arc surface 25. The X-shaped support structure device greatly simplifies a mold structure, greatly lowers mold manufacturing cost, greatly enhances the intensity and rigidity of a pivot shaft of an X-shaped support structure, greatly enhances the durability, overcomes the influence of sticky liquid on the X-shaped support structure device, further enhances product quality and can be widely applied to computer keyboards and key switch devices for key pressing operation.

Description

Technical field [0001] The present invention relates to a key switch device for performing keystroke operations, and more particularly to a key switch device incorporated in a keyboard as an input device of an electronic device. The invention also relates to a keyboard provided with a plurality of such key switch devices. Background technique [0002] In thin, low-profile keyboards that are installed in portable electronic devices such as notebooks or palmtop computers, it is required to promote the reduction of the height of the key switch device for typing operations, and to improve its operability, that is, to feel good--- --. In general, a key switch device that can be used in a low-height keyboard is provided with: a support plate (for example, a metal sheet or a lower bottom plate of a keyboard), and a keycap arranged on the support plate, interlocking with each other so as to be on the support plate. A pair of link members that support the keycap are guided upward a...
