Problems solved by technology

There is also another similar keyboard on the market. The keycap adopts a combined structure, and the touch film is sandwiched in this combined structure, which can avoid the perforated structure, but increases the overall thickness of the keycap and increases the assembly effort. the complexity

Embodiment Construction

[0038] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0039] see Figure 1 to Figure 3 . figure 1 is a partial top view of a keyboard according to an embodiment, figure 2 for figure 1 The cross-sectional view along the line X-X, image 3 for figure 2 The cross-sectional view when the first keycap is pressed. The keyboard 1 according to one embodiment comprises a shell 10, a base 12, a first keycap 14, a first lifting mechanism 16, a second keycap 18 and a second lifting mechanism 20; the first keycap 14, the second keycap 18 Contours are drawn as hidden lines on figure 1 middle. The first keycap 14 and the second keycap 18 are disposed above the base 12 . The first lifting mechanism 16 is disposed between the base 12 and the first keycap 14 , and the first keycap 14 can move up and down relative to the base 12 ...

Abstract

The invention discloses a keyboard and a key structure thereof. The key structure comprises a base, a key cap, a lifting mechanism, a touch circuit part and an outer covering layer. The key cap is connected to the base through the lifting mechanism so as to move up and down relative to the base. The touch circuit part is arranged on the top surface of the key cap. A connection circuit part extends from the touch circuit part. The outer covering layer covers the touch circuit part and at least one part of the connecting circuit part at the same time. Therefore, the key structure can provide a touch function without excessively increasing the overall thickness. The keyboard provided by the invention comprises a plurality of key structures, so that a touch function can be provided without excessively increasing the overall thickness.

Description

technical field [0001] The present invention relates to a keyboard and a key structure, in particular to a keyboard and a key structure capable of providing a touch function. Background technique [0002] Generally, widely used human-computer input devices are mainly keyboards and mice. Generally, a notebook computer or a tablet computer has a touchpad or a touchable screen, so the mouse can be omitted. In principle, a desktop computer or a smart TV still needs a mouse. In this regard, there are keyboards combined with touch functions on the market to reduce the number of external devices. There is a keyboard on the market, which is provided with a touch film in the key area to provide key and touch functions in the key area at the same time. The touch film can be arranged under the keycap, but it needs to have a hole to avoid the structure of the keycap (such as the connection structure with the supporting frame). Holes will reduce the stiffness of the touch film and in...
