Structure of notebook computer keyboard

Abstract

The invention discloses a structure of a notebook computer keyboard, comprising a substrate, a flexible circuit board with key functions, silicone rubber keys, shear pins and key caps; the silicone rubber keys are directly adhered on the substrate; the key caps are connected with the substrate through the shear pins; the flexible circuit board is arranged below the substrate; and avoidance holes for assembling a computer are arranged on the flexible circuit board. According to the structure of the notebook computer keyboard, because the flexible circuit board which plays the roles of the keys is arranged at the bottom of the substrate, mechanism holes which are matched with key position mechanisms do not need to be arranged on the flexible circuit board, so that the number of the mechanical holes is greatly reduced, and the manufacturing of the circuit board is simpler. According to the structure of the notebook computer keyboard, a light guiding plate can be integrated with the circuit board, a conductive line which realizes the key functions is arranged on the light guiding plate, and a light-emitting diode (LED) lamp which provides a light source is adhered, so that a backlight plate, a power supply line, a shade chip and other materials in an original keyboard design are reduced, and simultaneously elements and devices of a computer main board for providing power supplies are reduced.

Description

[0001] technical field [0002] The invention relates to the field of notebook computers, in particular to a structure of a notebook computer keyboard. Background technique [0003] The flexible circuit board with button function of the existing notebook computer keyboard is attached to the metal substrate of the keyboard, and it is necessary to provide mechanism holes for matching the key mechanism. Due to the large number of mechanism holes, the production of the circuit board is relatively complicated. [0004] If the existing laptop keyboard needs to be illuminated, a backlight module must be attached. The backlight module is a flexible circuit board (FPC) with a metal substrate plus a light source (SMD LED lamp) plus auxiliary materials such as a light guide plate. Attached to the back of the ordinary keyboard, not only the cost is high, but also the thickness of the keyboard is increased. Since the light source needs to be powered separately, the computer motherboard a...

[0003] The flexible circuit board with button function of the existing notebook computer keyboard is attached to the metal substrate of the keyboard, and it is necessary to set the mechanism holes for the key mechanism. Due to the large number of mechanism holes, the production of the circuit board is more complicated.

[0004] If the existing laptop keyboard needs to be illuminated, a backlight module must be attached. The backlight module is a flexible circuit board (FPC) with a metal substrate plus a light source (SMD LED lamp) plus auxiliary materials such as a light guide plate. Attached to the back of the ordinary keyboard, not only the cost is high, but also the thickness of the keyboard is increased. Since the light source needs to be powered separately, the computer motherboard also needs a module to provide power and connection positions for it, and it also occupies the design space of the motherboard to varying degrees.
