Embodiment Construction

[0039] 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.

[0040] See first figure 1 , figure 1 It is a schematic diagram of an electronic device according to an embodiment of the present invention. In the embodiment of the present invention, one or more key devices 10 can be disposed on the input module 21 of the electronic device 20 (such as a keyboard of a notebook computer or a personal computer) to provide input signals to the aforementioned electronic device 20 . For example, when the user presses the button mechanism 10, the input signal can be transmitted to the display module 22 (such as a screen) of the electronic device 20, so that the display module 22 displays a corresponding image.

Abstract

The invention discloses a key device, which comprises a key cap, a bottom plate, a first support, a second support, a first clamping seat and a second clamping seat, wherein the bottom plate is arranged below the key cap; the first support and the second support are rotatably connected with the key cap and the bottom plate; the first clamping seat and the second clamping seat are arranged on the bottom plate, protrude towards the key cap, and are rotatably connected with the first clamping seat and the second clamping seat respectively; the first clamping seat is provided with a first protruding section, a first non-right-angle section and a first lower straight section, the first protruding section protrudes most and faces the direction away from the second clamping seat, the first lowerstraight section is connected with the bottom plate, and the first non-right-angle section is connected with the first protruding section and the first lower straight section; and when the key cap moves relative to the bottom plate, the first support is limited by the first non-right-angle section and the first lower straight section of the first clamping seat, and then the maximum height of the key cap is limited. According to the key device, the maximum height of the key cap can be reduced only by utilizing the design of the first clamping seat and the second clamping seat, and the two design targets of key cap height reduction and height sharing are both considered.

Description

technical field [0001] The invention relates to a key device. More specifically, the present invention relates to a key device with a deck. Background technique [0002] Many electronic devices contain key devices for input. At present, many mechanical key devices use pivoted supports as lifting mechanisms to support the keycaps and provide a mechanism for the keycaps to move up and down. For example, the scissor foot bracket is used as the lifting mechanism. . When assembling the lifting mechanism, its supporting parts generally require moderate deformation to connect smoothly. [0003] However, in order to meet the miniaturization requirements of today's electronic equipment, the height of the key caps of the aforementioned key device needs to be lowered accordingly. Therefore, how to provide a key device with a low height becomes an important issue. Contents of the invention [0004] In view of the problems in the prior art, the present invention provides a button d...
