Keyboard with touchpad buttons

Abstract

The invention relates to a keyboard with touchpad buttons. The keyboard with the touchpad buttons comprises a keyboard shelf, a mainboard and a plurality of keys. The mainboard and the plurality of keys are disposed on the keyboard shelf. The keys are opposite to a plurality of switches on the surface of the mainboard. On the basis, the touchboard and the keys of a conventional keyboard are combined together in a mechanical structure. The above at least one key comprises a key body disposed on the keyboard shelf, the touchpad adjacent to the key body and a touch chip which is electrically connected with the touchpad and the mainboard and is used for monitoring operations of the touchpad and outputting position information to the mainboard. The operations of the touchpad are still controlled by an independent touch chip but not a controller chip of the keyboard, so as to prevent response sensitivity of the keyboard from reducing. The touchpad is used for providing an orientation function, so that a hand of a user can operate a mouse without leaving the keyboard.

Description

technical field [0001] The present invention relates to a keyboard, in particular to a keyboard with keys on a touch panel. Background technique [0002] Due to space constraints, notebook computers are usually equipped with smaller keyboards, and some notebook computers use a touchpad or a trackpoint to implement mouse functions in order to provide more convenient operations. figure 1 It is a schematic diagram of a notebook computer equipped with a pointing stick 10 and a touchpad 12 at the same time. Usually, the position of the pointing stick 10 is arranged in the gap between the keys of the keyboard, and the position of the touchpad 12 is arranged on the lower side of the keyboard key area. A left button 14 and a right button 16 configured with a mouse function are adjacent to the touchpad 12 . Some notebook computers only use the pointing stick 10 instead of the touchpad 12 in order to reduce the size of the keyboard as much as possible, but the operation of the pointi...

Some notebook computers only use the pointing stick 10 instead of the touchpad 12 in order to reduce the size of the keyboard as much as possible, but the operation of the pointing stick 10 is not as convenient as the touchpad 12

Although using a touchpad or pointing stick is beneficial for users to work for a long time, the hardware cost is high and additional space is required

[0003] Guan Guo Patent No. 5,841,423 digs long grooves on the blank keys of the keyboard and embeds cylindrical rod sensors to detect sliding, rotating or pressing to control the cursor on the screen. Although the space can be reduced, the structure is very complicated and It is easy to move the cursor
