Technical field
The present invention about a kind of key board unit, especially about the key board unit with lighting function.
Background technology
Common computer peripheral equipment input media comprises mouse apparatus, key board unit and Trackball device etc., and wherein key board unit directly can key in word and symbol gives computer, is therefore quite subject to the attention of user and input media manufacturer.
Refer to Fig. 1, it is the surface structure schematic diagram of existing key board unit.The surface of existing key board unit 1 has multiple button 10, those buttons 10 are classified as general key 101, numerical key 102 and function key 103 etc., those buttons produce corresponding signal for user presses with finger and give computer, computer is made to perform touched keypress function, such as general key 101 is in order to symbols such as inputting English letters, numerical key 102 in order to input numeral, function key 103 then in order to provide various function, such as F1 ~ F12 etc.Wherein existing key board unit 1 is the key board unit of a notebook computer.
Along with the evolution of science and technology, keyboard manufacturer is devoted to research and develop the various key board unit with specific function to meet the various demands of different users, illustrates for lighting keyboard.The outward appearance of existing lighting keyboard is roughly the same with the outward appearance of existing key board unit 1, but provides the function of key light emitting because of lighting keyboard, therefore its inner structure is different from the existing key board unit without lighting function.The inner structure of existing lighting keyboard is below described.Refer to Fig. 2, it is the structural profile schematic diagram of existing lighting keyboard.Existing lighting keyboard 2 comprises multiple button 20, film switch circuit 21, light guide plate 22, backlight module 23, back up pad 24, reflector plate 25 and a base.Button 20 comprises button cap 201, scissor Connection Element 202 and a flexible member 203.In existing lighting keyboard 2, above-mentioned each element is basipetal to put in order as button cap 201, scissor Connection Element 202, flexible member 203, film switch circuit 21, back up pad 24, light guide plate 22, reflector plate 25 and base, backlight module 23 is positioned at the side of film switch circuit 22, wherein existing lighting keyboard 2 is the key board unit of a notebook computer (not being shown in figure), and base is arranged on this notebook computer.
In button 20, button cap 201 is revealed in outside existing key board unit 2 and can be pressed by user, scissor Connection Element 202 is in order to connect button cap 201 and back up pad 24, and flexible member 203 passes scissor Connection Element 202 and contacts with button cap 201 and film switch circuit 21 respectively.Film switch circuit 21 to comprise on one wiring board 211, separation layer 212 and once wiring board 213, wherein going up wiring board 211, separation layer 212 and line plate 213 is all with made by light transmissive material, and light transmissive material is polycarbonate (Polycarbonate, PC) made by material or tygon (polyethylene, PE) material.Upper wiring board 211 has multiple upper contact 2111, separation layer 212 is positioned at the below of wiring board 211, and the multiple separation layer perforates 2121 had corresponding to multiple upper contact 2111, and once wiring board 213 is positioned at the below of separation layer 212, has corresponding to the multiple lower contact 2131 of multiple upper contact 2111 and form multiple keyswitch 214 with multiple upper contact 2111.
Backlight module 23 comprises in a luminous circuit board 231 and multiple light-emitting component 232(figure and only shows two), luminous circuit board 231 is positioned at the below of film switch circuit 21, multiple light-emitting component 232 is given in order to provide an electric power, and multiple light-emitting component 232 to be arranged on luminous circuit board 231 and to stretch into multiple reflector perforate 251 of reflector plate 25 and multiple light guide plate perforates 221 of light guide plate 22, when multiple light-emitting component 232 obtains electric power, it is produced multiple light beam B, and multiple light beam B is projected to light guide plate 22, wherein multiple light-emitting component 232 is lateral LED.Light guide plate 22 makes it be projected to button cap 201 in order to guide multiple light beam B.In Fig. 2, back up pad 24 between film switch circuit 21 and light guide plate 22, in order to carry button cap 201, scissor Connection Element 202, flexible member 203 and film switch circuit 21.Reflector plate 25 is arranged at the below of light guide plate 22, in order to reflect multiple light beam B, multiple light beam B is up projected, and avoid light beam B to waste, wherein the dual side-edge 252 of reflector plate 25 up bends and multiple sides 222 of coated light guide plate 22, with the phenomenon avoiding light guide plate 22 that side 222 light leak occurs.
In existing lighting keyboard 2, each button cap 201 has a bright dipping region 2011, and bright dipping region 2011 is the position at letter or symbol place, wherein the position in bright dipping region 2011 corresponds to the position of the guide-lighting site 223 in light guide plate 22, so that light beam is up guided to its bright dipping region 2011 through guide-lighting site 223.In back up pad 24, it comprises multiple back up pad perforate 241, and multiple back up pad perforate 241 corresponds to multiple guide-lighting site 223 and multiple bright dipping region 2011.On the other hand, because film switch circuit 21 is with made by light transmissive material, multiple light beam B is able to through film switch circuit 21.By this, multiple light beam B is able in response to multiple guide-lighting site 223 sequentially through multiple back up pad perforate 241 and film switch circuit 21, to be projected to multiple bright dipping region 2011, the letter on its button cap 201 or symbol is made then to be able to printing opacity and to have illumination effect.
Specifically, because back up pad 24 is with made by light-proof material, generally speaking, back up pad 24 is with made by metal material, it will stop that multiple light beam B passes through, and therefore, back up pad 24 must be provided with multiple back up pad perforate 241 and pass through for multiple light beam B.
