Problems solved by technology

The current power button is mostly an independent button, which is designed separately from the keyboard buttons, so that it cannot be integrated with the keyboard, resulting in poor space utilization of the keyboard
In addition, the structural design of the power button is also different from that of the keyboard. It is necessary to set the power button on the main board of the notebook computer, and occupy the space of the main board, so further improvement is needed.

Abstract

The invention discloses a key structure, comprising a bottom plate, a pivot structure, a key cap, a thin film circuit board and a dome structure. The bottom plate has a limiting unit. The pivot structure is slidably provided on the bottom plate and includes a first pivot member and a second pivot member. A key cap is disposed on the pivot structure and is connected to the pivot structure, and thekey cap moves up and down with respect to the base plate by rotation of the first pivot member relative to the second pivot member. A membrane circuit board is arranged on that bottom plate, and the membrane circuit board comprises a switch element. The dome structure is abutted between the pivot structure and the thin film circuit board. The dome structure comprises a metal film elastic piece, and the metal film elastic piece is positioned above the switching element. The invention can increase the pressing feel of the keys.

Description

technical field [0001] The invention relates to a key structure, and in particular to a key structure for improving the pressing feeling. Background technique [0002] As the technology becomes more and more mature, the performance and design of notebook computers are getting better and better, and the requirements for keyboards are relatively higher. Regarding the quality of the keyboard, in addition to requiring each key to have a uniform backlight, it is also required to provide a comfortable feel and a short pressing stroke when the key is pressed, so as to meet the thin and light requirements of the notebook computer. [0003] At present, the power button of the notebook computer mostly adopts a rubber dome to support under the keycap, and the keycap of the power button is usually printed with special characters for users to identify. Most of the current power buttons are independent buttons, which are designed separately from the buttons of the keyboard, so that they ...
