Please refer to shown in Fig. 5 to 9, the key switch device of first embodiment of the present utility model comprises substrate 20, keycap 22, first coupling member 24, second coupling member 26 and elastic component 28.
Have film circuit board 21 on this substrate 20, and substrate 10 can be respectively equipped with first axis hole 202 and first guide groove 204, respectively in order to first coupling member 24 and second coupling member 26 to be set.
This keycap 22 is positioned at standby primary importance (as shown in Figure 8) in leaving this substrate 20 and is positioned between the second place (as shown in Figure 9) that is depressed and moves.And as shown in Figure 6, this keycap 22 can have second axis hole 222 and second guide groove 224, respectively in order to first coupling member 24 and second coupling member 26 to be set.This keycap 22 can be provided with backstay 226 again, in order to engage location (as shown in Figure 7) with first coupling member 24.
This first coupling member 24 can become ㄈ font, square shape or other shapes substantially, and present embodiment is an example with the ㄈ font.And its both ends (that is, first end and the second end) can be respectively equipped with first rotating shaft 242 and first guide rod 244, be arranged at first axis hole 202 of this substrate 20 and second guide groove 224 of this keycap 22 with rotating manner and move mode respectively.This first coupling member 24 can have pivot or pivot hole again, and present embodiment is an example with pivot hole 246, can be in order to articulate with second coupling member 26.In addition, this first coupling member 24 can be provided with location notch 248, engages location (as shown in Figure 7) with the backstay 226 of keycap 22 in order to move to above-mentioned primary importance when keycap 22 when (as shown in Figure 8).
This second coupling member 26 becomes ㄈ font, square shape or other shapes substantially, and present embodiment is example with the square shape.And its both ends (that is the 3rd end and the 4th end) is respectively equipped with second guide rod 264 and second rotating shaft 262, is arranged at first guide groove 204 of this substrate 20 and second axis hole 222 of this keycap 22 with move mode and rotating manner respectively.This second coupling member 26 can have pivot or pivot hole again, and present embodiment is an example with pivot 266, is articulated in order to the pivot hole 246 with first coupling member 24.In addition, first guide groove 204 of this substrate 20 is along the little groove of moving direction convergent, and the direction (direction shown in arrow A among Fig. 8) that this moving direction moves for second guide rod 264 when keycap 22 moves to primary importance by said second position.That is first guide groove 204 can be made of (shown in Fig. 5 and 8) the inclined plane, this second guide rod 264 can be positioned in first guide groove 204, and then more can not produce and rock.
This elastic component 28 can be made of rubber, and is arranged between this substrate 20 and the keycap 22, makes keycap 22 move to above-mentioned primary importance (as shown in Figure 8) by its elasticity.And when keycap 22 is depressed and moves to said second position when (as shown in Figure 9), this elastic component 28 touches in this circuit board 21 and makes circuit board 21 conductings.
Please refer to shown in Figure 10 to 14, wherein identical or suitable with Fig. 5 to 9 part is put on identical symbol, to omit its explanation.The difference of the key switch device of the key switch device of second embodiment of the present utility model and first embodiment is: first coupling member 24 of second embodiment is provided with backstay 226a, and first coupling member 24 of first embodiment is provided with location notch 248, and the keycap 22 of second embodiment is provided with location notch 248a, and the keycap 22 of first embodiment is provided with backstay 226; Other parts are identical with first embodiment, so can obtain and the first embodiment identical functions.
Please refer to shown in Figure 15 to 19, wherein identical or suitable with Fig. 5 to 9 part is put on identical symbol, to omit its explanation.The difference of the key switch device of the key switch device of the 3rd embodiment of the present utility model and first embodiment is: the key switch device of the 3rd embodiment is not established location notch 248 and backstay 226, but 2 second guide grooves 224 of keycap 22 are along the relative little groove (shown in Figure 16 and 17) of convergent of first moving direction (direction shown in arrow B among Figure 18), and the direction (as shown in figure 18) that first moving direction shown in the arrow B moves for first guide rod 244 of first coupling member 24 when keycap 22 moves to primary importance by the second place.And this second guide groove 224 can be made of the inclined plane, and the free end of first guide rod 244 can have the portion of chamfering (for example forming chamfering, shown in Figure 15 and 17).So, when keycap 22 moved to primary importance, first guide rod 244 was stuck between second guide groove 224 (as shown in figure 17), keycap 22 can be located, and then not produce and rock.
Other parts as for the 3rd embodiment are identical with first and second embodiment, for example, first guide groove 204 of substrate 20 is along the little groove of the second moving direction convergent, and the direction (direction shown in arrow A among Figure 18) that this second moving direction moves for second guide rod 264 when keycap 22 moves to primary importance by the second place.That is this first guide groove 204 can be made of (shown in Figure 15 and 18) the inclined plane, second guide rod 264 can be positioned in first guide groove 204, and then more can not produce and rock.Certainly if second coupling member 26 is the ㄈ font, then first guide groove 204 also can have two, and be along the relative little groove of convergent of second moving direction (direction shown in arrow A among Figure 18) as second guide groove 224, otherwise, second guide groove 224 can be along first moving direction (direction shown in arrow B among Figure 18) groove that convergent is little as first guide groove 204 also, therefore, also have and first and second embodiment identical functions.
According to the utility model key switch device, because keycap has backstay or location notch, and first coupling member has location notch or backstay, when keycap is positioned at primary importance, backstay is sticked in location notch, and then keycap is located, and rocks so can reduce keycap.And because second guide groove is along the little groove of the relative convergent of first moving direction, and first moving direction is the direction that first guide rod moves when keycap moves to primary importance by the second place, rocks so also can reduce keycap.First guide groove is along the little groove of the second moving direction convergent again, and second moving direction is the direction that second bar moves when keycap moves to primary importance by the second place, does not rock so more can not produce.
