Figure 1 is a top view of the first embodiment of the mechanical keyboard of this invention. Figure 2 is an exploded view of the first embodiment of the mechanical keyboard of this invention. For clarity of description, FIG. 1 omits the upper key cap 80 in FIG. 2. As shown in FIGS. 1 and 2, the mechanical keyboard 100 includes a switchable button 1 and a stepping motor 9.

As shown in FIG. 2, the switchable button 1 includes a positioning plate 10, a lever assembly 20, a movable shaft 30, a button base 40, a fixed cover 50 and a mechanical shaft assembly 60. The positioning plate 10 is provided with a positioning opening 11, a sliding opening 13 and an assembly opening 15, and the positioning opening 11 is in communication with the sliding opening 13. The shift lever assembly 20 includes a clamping member 21, a connecting rod 23 and a trigger member 25. The clamping member 21 and the triggering member 25 respectively extend from the two ends of the connecting rod 23 approximately along the normal direction of the connecting rod 23. Here, "approximately" means basically, but allows partial angular deviation. The clamping member 21 is clamped in the assembly opening 15, and the trigger member 25 is located in the sliding opening 13. The movable shaft 30 is connected to the trigger 25 and is disposed in the sliding opening 13 and is substantially orthogonal to the trigger 25.

The key base 40 is partially disposed in the positioning opening 11, and the key base 40 is provided with an accommodating groove 41, and the accommodating groove 41 is connected to the sliding opening 13 (see FIGS. 4 to 6 and 8 to 10). A spring 45 (see FIGS. 4 to 6 and FIGS. 8 to 10) is provided in the accommodating groove 41, and the spring 45 abuts against the movable shaft 30. In some embodiments, a buffer 47 is further provided between the spring 45 and the movable shaft 30 to avoid the abrasion of the movable shaft 30.

The fixed cover 50 is assembled with the key base 40 and has an upper opening 51. After the fixed cover 50 and the key base 40 are assembled, there is a space allowing the movable shaft 30 to enter and exit (see FIGS. 4 to 6 and 8 to 10). The mechanical shaft assembly 60 includes a mechanical shaft 61 and a resilient element 63. The resilient element 63 is installed in the key base 40 and assembled with the lower end of the mechanical shaft 61 to provide elastic force for the mechanical shaft 61 to recover when pressed. The top end of the mechanical shaft 61 passes through the upper opening 51, and the mechanical shaft 61 includes a contact portion 611. Further, the switchable key 1 further includes a key cap 80, which is assembled with the top end of the mechanical shaft 61.

The switchable button 1 can be switched through the stepping motor 9. The keycap 80 is omitted below to clearly understand the correspondence between the mechanical structures. Figure 3 is a top view of the switchable button in the first state. 4 to 6 are cross-sectional views of the switchable key operating in the first state. Figure 7 is a top view of the switchable button in the second state. 8 to 10 are cross-sectional views of the switchable key operating in the second state. The stepping motor 9 receives the actuation signal and pushes the clip 21 to move in the assembly opening 15 to drive the movable shaft 30 to abut against the abutting portion 611 or to move away from the abutting portion 611.

Referring again to FIG. 1, the mechanical keyboard 100 further includes a trigger button 71 and a circuit board 73. The trigger button 71 and the circuit board 73 can be installed in the casing 70 of the mechanical keyboard 100. The trigger button 71 and the stepping motor 9 are respectively connected to the circuit board 73. When the trigger button 71 is pressed, the circuit board 73 generates an actuation signal and transmits it to the stepping motor 9 to activate the stepping motor 9 to start and push the card connection The piece 21 translates in the assembly opening 15.

Here, the position of the switchable button 1 and the way of generating the trigger are only examples, not for limitation. For example, the stepping motor 9 can also directly receive an actuation signal from a computer, or the trigger button 71 can also be set as a micro-controller or a mechanical pressing control, and the control signal is directly generated by it.

As shown in Figures 3 to 6, the switchable button 1 is in the first state, and the clamping member 21 is in the first position in the assembly opening 15. At this time, the movable shaft 30 is away from the abutting portion 611, and when the mechanical shaft 61 is During pressing and rebounding, the spring 45 is not affected. Therefore, in the first state, the switchable button 1 only relies on the elasticity of the resilient element 63 to recover.

In addition, as shown in FIGS. 7 to 10, when the stepper motor 9 drives the clamping member 21 to translate from the first position to the second position in the assembly opening 15. The trigger 25 drives the movable shaft 30 to slide in the sliding opening 13 until it abuts the abutting portion 611, so that the switchable button 1 is converted into the second state. At this time, when the mechanical shaft 61 is pressed, the mechanical shaft 61 drives the movable shaft 30 and the shift lever assembly 20 to move down and compress the spring 45. Since the switchable button 1 in the second state receives the resilience of the resilience element 63 and the spring 45 at the same time, the resilience speed increases and the tactile sensation of pressing also changes.

Figure 11 is a top view of the second embodiment of the mechanical keyboard of the present invention. Figures 12 and 13 are three-dimensional views of the switchable button in the second embodiment in the first state and the second state, respectively. The difference from the previous embodiment is that the embodiment of Figure 11 has a plurality of switchable buttons 1, Positioning plate 10, shift lever assembly 20 and stepping motor 9. In this embodiment, the mechanical keyboard 100 includes a plurality of switchable keys 1. The difference from the previous embodiment is that the positioning plate 10 and the lever assembly 20 have been used to drive the entire set of switchable buttons 1. The structures of the movable shaft 30, the key base 40, the fixed cover 50, and the mechanical shaft assembly 60 of the switchable button 1 are substantially the same as those of the previous embodiment, and will not be repeated.

As shown in FIGS. 11 to 13, although not clearly shown in the three-dimensional view, it can be understood by referring to the position of FIG. 11 and also referring to FIG. 2 that the positioning plate 10 is provided with an assembly opening 15 and a plurality of key areas 10A. Each key zone 10A includes a positioning opening 11 and a sliding opening 13. As shown in FIGS. 12 and 13, the shift lever assembly 20 includes a clamping member 21, a linkage member 27, and a plurality of trigger members 25. The clamping member 21 and the triggering member 25 extend substantially along the normal direction of the linkage member 27. The clamping member 21 is clamped in the assembly opening 15 and the triggering member 25 is respectively located in the sliding opening 13 of the key zone. The stepping motor 9 is connected to the link 27, receives the actuation signal, pushes the clip 21 to move in the assembly opening 15, and synchronously drives the movable shafts 30 to abut against each abutment portion 611 through the link 27, or to move away from each abutment.部611.

As shown in FIG. 12, at this time, the switchable button 1 is in the first state, and all the movable shafts 30 are far away from the abutting portion 611. When a single switchable button 1 is pressed and rebounds, it is similar to FIGS. 4 to 6 The state is the same, the spring 45 is not affected.

As shown in FIG. 13, the stepping motor 9 integrally drives the trigger 25 and the movable shaft 30 to move through the link 27, so that the movable shaft abuts the abutting portion 611, and all the switchable buttons 1 are converted to the second state. When the single switchable button 1 is pressed and bounced, its state is the same as that of FIGS. 8 to 10.

In summary, the mechanical keyboard 100 is designed with the switchable button 1, allowing the user to selectively switch between specific buttons or multiple buttons, and can be used for different applications through the difference in touch Switching between situations can also achieve the effect of avoiding false touches and increasing efficiency.
