Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a kind of notebook computer keyboard switch, and more particularly to a keyboard switch that can be easily assembled and disassembled, the interlocking rack can be smoothly rotated, and the keycap does not swing up and down or back and forth.

[0002]

[Prior art]

 FIG. 1 shows a kind of well-known notebook computer keyboard switch 10a, which includes a key cap 11a, an elastic trigger body 12a, a first interlocking support 13a, a second interlocking support 14a, a flexible circuit board 15a, and It is provided with a bottom plate 16a. The keycap 11a is located above the first interlocking support 13a and the second interlocking support 14a installed in a cross shape, and the keycap 11a is vertically moved under the guidance of the first interlocking support 13a and the second interlocking support 14a. When moving in parallel, the elastic trigger body 12a below the keycap 11a presses the flexible circuit board 15a or moves away from the flexible circuit board 15a, thereby causing the switch to perform on and off operations.

However, in the keyboard switch of the well-known notebook computer described above, many screws are usually used to fix many components such as the elastic trigger body 12a, the flexible circuit board 15a, and the bottom plate 16a. It was relatively inconvenient to assemble and disassemble. Also, the smoothness of rotation of the first interlocking support 13a and the second interlocking support 14a was affected by the sharp angles and fluffs of the fixing holes 17a and 18a of the bottom plate 16a. Further, since the fixing hole 18a of the bottom plate 16a is designed to have one slope, the keycap 11a may swing up and down and back and forth. In addition, the first interlocking support 13a and the second interlocking support 14a have a single relatively rigid body design between the shafts 19a and 20a, which is not a convenient design that has elasticity and can be deformed. Therefore, the keycap 11a may be broken due to pressure during assembly. Further, at the time of assembly, a slight front gap is provided below the key cap 11a for the entry of the shaft body 20a of the second interlocking support 14a, so that a specific angle is required when the key cap 11a is attached. Therefore, the keycap 11a was easily damaged due to an erroneous pressure applied to the keycap 11a. Moreover, the strength of the two sides of the first interlocking support 13a and the second interlocking support 14a, which have two U-shapes, is not sufficient, and the left and right swings of the keycap 11a are likely to occur, and the first interlocking support 13a and Since there is no function of guiding the elastic trigger body 12a to the two sides of the second interlocking support 14a, the elastic trigger body 12a was easy to move. Furthermore, the elastic trigger body 12a and the keycap 11a do not have a good positioning structure, and it is difficult to ensure stable electrical contact when the keycap 11a is pushed. Also, when the keyboard was attached to the notebook computer, its stability became poor due to the large amount of heat generated by the notebook computer during the operation process. As described above, the keyboard switch of the well-known notebook computer has obvious inconveniences and drawbacks in actual use, and its improvement has been awaited.

The two rotating shafts can elastically enter the two interlocking support hooks of the keycap, thereby facilitating the coupling of the first interlocking support and the keycap, and the keycap is damaged by pressing force during assembly. In addition, the opening-type elastically deformable arcuate cut of the second interlocking support allows the two slide shafts to elastically enter the fixing grooves of the two interlocking supports of the key cap. This makes it relatively easy to connect the second interlocking support and the keycap, and prevents the keycap from being damaged by forcing pressure when assembling. The problem is to prevent damage due to erroneous pressure on the key cap due to the elastic design of the slide shaft.

Fifthly, the present invention provides a keyboard switch of the notebook computer, wherein one arcuate connecting body is provided on the first interlocking rack to position the elastic trigger body and guide the elastic trigger body. By using this, the elastic trigger body is prevented from being displaced, and the elastic trigger body, the flexible circuit board and the bottom plate are provided with perforations, punch holes, etc., thereby generating the notebook computer main body.

It is possible to guide the connection between the first interlocking support frame 20 and the second interlocking support frame 30.

In addition, since the first interlocking frame 20 of the present invention is designed to have one opening elastically deformable between the two rotary shafts 24, the two rotary shafts 24 elastically move to the keycap 10. The two interlocking support hooks 13 of the key cap 10 can be inserted into the two interlocking support hooks 13 of the keycap 10, and therefore the first interlocking support frame 20 and the keycap 10 can be relatively easily coupled to each other. Moreover, due to the elastic design of the two rotating shafts 24, the keycap 10 is not damaged by the wrong pressure of the keycap 10. Further, since the arc-shaped connecting body 23 of the first interlocking support 20 has a function of facilitating the positioning of the elastic trigger body 40 and a function of guiding the elastic trigger body 40, it is positioned at the elastic trigger body 40. It is difficult to cause misalignment. Also, the arcuate cut 34 of the second interlocking support frame 30 elastically allows the two slide shafts 25 to enter the two interlocking support frame fixing grooves 14 of the keycap 10, so that the second interlocking support frame 30 and the keycap 10 are not locked. Of the keycap 10 is relatively easy to connect, and the fixing groove 14 of the keycap 10 is prevented from being broken due to excessive pressure when assembling, and the elastic design of the two slide shafts 35 also prevents the keycap 10 from being erroneously pressed. 10 damage is prevented.
