Problems solved by technology

[0007] 2. The plastic connecting rod structure is relatively small, there is a hole shaft structure, and the production process is relatively complicated
[0008] 3. The production and assembly process of the existing keyboard is complicated: injection molding production of plastic connecting rods--stamping production of support plate sheet metal--assembling plastic connecting rods into plastic X support structure devices--assembling X support structure devices on support plates , the existing keyboard assembly process has low efficiency and high cost
[0012] 6. Although the plastic connecting rod is made of high-strength engineering plastics to improve the rigidity, the rigidity is still not enough to further improve the operability. As a result, when the finger hits the edge of the keycap, there will be a side of the keycap that is hit by about 0.5mm. Empty stroke of displacement

Embodiment 1

[0116] see image 3 , The sheet metal connecting rod structure of the present invention is made of keycap 1, rubber elastic ring 11, support plate 15, membrane switch sheet 12, inner connecting rod 4, outer and inner connecting rod 8.

[0117] see figure 1 , figure 2 , image 3 1. The keycap 1 is in the shape of a traditional keycap. There is a keycap connection part on the concave bottom surface of the keycap 1 . The keycap connection part is composed of a sliding part 3 and a rotating part 2 .

[0118] see Figure 4 1. There is an inner connecting rod through hole 16 near the middle part of the inner connecting rod plate surface 18 of the inner connecting rod 4, and there is a flanging and bending edge 17 along the edge of the inner connecting rod through hole 16, and on the left and right sides of the flanging and bending edge 17 There is an inner connecting rod bending edge 19 perpendicular to the inner connecting rod plate surface 18, and an upper hinge shaft 10 is a...

Embodiment 2

[0135] see Figure 18 1. There is an inner connecting rod through hole 16 near the middle part of the inner connecting rod plate surface 18 of the inner connecting rod 4, and there is a flanging and bending edge 17 along the edge of the inner connecting rod through hole 16, and on the left and right sides of the flanging and bending edge 17 There is an inner connecting rod bending edge 19 perpendicular to the inner connecting rod plate surface 18,

[0136] There is an inner sliding shaft 7 on the upper outer side of the bending edges 19 of the two inner connecting rods. The inner sliding shaft 7 directly stretches the circular boss on the plate surface or directly before the bending edges 19 of the two inner connecting rods are bent. It is fixed on the board by automatic riveting, welding and other processes. There is 21 of inner connecting rod giving way space below flanging bending edge 17.

[0137] see Figure 19 1. The support plate 15 formed with the support plate rota...

Embodiment 3

[0145] see Figure 21 , Figure 22 1. Near the middle part of the outer link plate surface 22 of the outer link 8, there is an approximate outer link through hole 23, and there is an upper flange 33 on the outer link above the outer link through hole 23, and the upper flange 33 of the outer link is oblique Upwards, the outer upper sliding shaft 6 that protrudes left and right symmetrically is formed at its end, and the outer upper sliding shaft 6 is formed by the process of flanging 33 end coils on the outer connecting rod.

[0146] All the other are the same with embodiment 1.

Abstract

The invention discloses a sheet metal rigid link structure which comprises a keycap (1), a rubber elastic ring (11) located between the keycap (1) and a thin film switch piece (12), the thin film switch piece (12) connected with the surface of a support plate (15), the support plate (15), connecting parts through which an inside connecting rod (4) and an outside connecting rod (8) are respectively connected with the keycap (1) and the support plate (15), connecting rod supports respectively formed by linkage between the outside connecting rod (8) and the inside connecting rod (4), and a linkage part which keeps synchronous linkage of the outside connecting rod (8) and the inside connecting rod (4). The sheet metal rigid link structure is characterized in that the structures of the outside connecting rod (8) and the inside connecting rod (4) are respectively that the outside connecting rod face (22) and the inside connecting rod face (18) are respectively connected with two left and right outside connecting rod outward bending edges (25) and two inside connecting rod bending edges (19). The sheet metal rigid link structure is high in structural strength, durable in use, better in hand feeling, high in production efficiency, low in material cost, low in process cost, and low in production energy consumption, and can be widely applied to computer keyboards, and various embedded keyboards.

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 notebook computers or palmtop computers, it is required to reduce 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-profile keyboard is provided with: a support plate (for example, a metal sheet or the lower bottom plate of the keyboard); a keycap arranged above the support plate; The upper pair of plastic link parts that guide and support the keycap in the vertical direction; the switch mechanism corresponding t...
