Description
Technical field
The present invention relates to the fields of input equipment, especially with respect to a kind of key board unit.
Background technology
The input equipment of common computer peripheral includes mouse apparatus, key board unit 1 and Trackball device etc., wherein key
Word and symbol are directly input to computer by disk device 1 for user, therefore are quite taken seriously.
The structure and function for illustrating existing key board unit 1 first, please refer to Fig.1~Fig. 2, and Fig. 1 is existing key board unit
Structural schematic diagram, Fig. 2 be Fig. 1 shown in key board unit mechanical open be pressed about keycap after schematic diagram.Key board unit 1
Including multiple a mechanical key structures 12 and circuit board 11, each mechanical key structure 12 includes keycap 121 and sets
The mechanical switch 124 being placed between keycap 121 and circuit board 11, and mechanical switch 124 includes shell 1241, push piece
1242, moving part 1243, the first shrapnel 1244, the second shrapnel 1245 and elastomer 1246, and shell 1241 can be used to house
Moving part 1243, elastomer 1246, at least part push piece 1242, at least partly the first shrapnel 1244 and at least part second
Shrapnel 1245.
In detail, shell 1241 includes pedestal 12411 and is covered on pedestal 12411 and has upper cover trepanning 12413
Upper cover 12412, and one end of push piece 1242 is upward through upper cover trepanning 12413 and contacts keycap 121, and the other end is then located at
In shell 1241 and be connected to moving part 1243, and moving part 1243 be set to pedestal 12411 centre and can be the bottom of relative to
Seat 12411 moves up and down, and moving part 1243 has and interlocks protrusion 12431, from the side wall of moving part 1243 toward the first bullet
The direction of piece 1244 extends and is formed.In addition, elastomer 1246 is set to the lower section of moving part 1243, one end is connected to gearing
Part 1243, the other end are fixed on pedestal 12411, and moving part 1243 is given to provide elastic force.
Furthermore the first shrapnel 1244 is adjacent to the side wall of pedestal 12411, there is the first electrical connection section 12441, springing part
12442 and the first fixed part 12443 for being fixed on pedestal 12411, the first fixed part 12443 be located at the first electrical connection section
Between 12441 and springing part 12442, and springing part 12442 is located in shell 1241, and can be protruded with the gearing of moving part 1243
Portion 12431 contacts and is swung relative to fixed part；And the first electrical connection section 12441 is then passed down through pedestal 12411 to contact simultaneously
It is electrically connected to circuit board 11；Also, the second shrapnel 1245 is set between moving part 1243 and the first shrapnel 1244, have second
Electrical connection section 12451, conducting portion 12452 and the second fixed part 12453 being fixed on pedestal 12411, the second fixed part
12453 between the second electrical connection section 12451 and conducting portion 12452, and conducting portion 12452 is located in shell 1241, and the
Two electrical connection sections 12451 are passed down through pedestal 12411 to contact and be electrically connected at circuit board 11.
During user presses keycap 121, keycap 121 can first push push piece 1242 down so that connect with it
The moving part 1243 connect, which synchronizes, to move down, meanwhile, elastomer 1246 generates elastic force by compression, and the company of moving part 1243
Dynamic protrusion 12431 contacts the springing part 12442 of the first shrapnel 1244 and moves down with respect to springing part 12442 and push against springing
Portion 12442 so that springing part 12442 is swung relative to the first fixed part 12443；Then, continue past move down in moving part 1243
After dynamic, the springing part 12442 in swing contacts and hits the conducting portion 12452 of the second shrapnel 1245 in which can take advantage of a situation, at this time circuit
Plate 11 can generate the corresponding push button signalling of output in response to the first shrapnel 1244 and the second being in contact for shrapnel 1245, such as figure
Shown in 2；Wherein, since the conducting portion 12452 that the springing part 12442 of the first shrapnel 1244 hits the second shrapnel 1245 will produce sound
It rings, therefore user's feedback feel for pressing keycap 121 can be provided.In addition, after user stops pressing keycap 121, moving part
1243 and push piece 1242 can be moved up in response to elastic force caused by elastomer 1246 so that keycap 121 sets back
As shown in Figure 1.
However, the shortcomings that existing key board unit 1, is, the keycap 121 of press-key structure 12 because with 1242 contact surface of push piece
Product is too small to be uniformly supported, therefore keycap 121 itself is whether suffered from front-rear direction or in the lateral direction
Shamble fixed phenomenon, and then influences the feel of user operationally, and the periphery of keycap 121 is especially pressed in user
When place, keycap 121 to rock degree more obvious.Therefore, existing key board unit and its press-key structure have improved space.
