Detailed Description

Fig. 1 is a top view of a first embodiment of the mechanical keyboard of the present invention. Fig. 2 is an exploded view of the first embodiment of the mechanical keyboard of the present invention. For clarity of description, the key cap 80 in the upper portion of FIG. 2 is omitted from FIG. 1. As shown in fig. 1 and 2, the mechanical keyboard 100 includes a switchable key 1 and a stepping motor 9.

As shown in fig. 2, the switchable key 1 includes a positioning plate 10, a lever assembly 20, a movable shaft 30, a key base 40, a fixed cover 50 and a mechanical shaft assembly 60. The positioning plate 10 has a positioning opening 11, a sliding opening 13 and an assembling opening 15, and the positioning opening 11 is communicated with the sliding opening 13. The lever assembly 20 includes a latch 21, a connecting rod 23 and a trigger 25. The engaging member 21 and the triggering member 25 extend from both ends of the link 23 substantially in the normal direction of the link 23, and "substantially" means that the angular deviation is basically allowed. The snap-in member 21 is snapped into 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, is disposed in the slide 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 a receiving groove 41, and the receiving groove 41 is communicated with the sliding opening 13 (see fig. 4 to 6 and 8 to 10). A spring 45 (see fig. 4 to 6 and 8 to 10) is disposed in the accommodating groove 41, and the spring 45 abuts against the movable shaft 30. In some embodiments, a buffer 47 is further disposed between the spring 45 and the movable shaft 30 to avoid wear of the movable shaft 30.

The fixing cover 50 is assembled with the key base 40 and has an upper opening 51, and the fixing cover 50 is assembled with the key base 40 and has a space for allowing the movable shaft 30 to enter and exit (see fig. 4 to 6 and 8 to 10). The mechanical shaft assembly 60 includes a mechanical shaft 61 and a resilient member 63, wherein the resilient member 63 is disposed in the key base 40 and is assembled with a lower end of the mechanical shaft 61 to provide a resilient force for the mechanical shaft 61 to return when pressed. The tip of the mechanical shaft 61 passes through the upper opening 51, and the mechanical shaft 61 includes the abutting portion 611. Further, the switchable key 1 further comprises a key cap 80, and the key cap 80 is assembled with the top end of the mechanical shaft 61.

The switchable button 1 can be switched to different states by the stepping motor 9. The key caps 80 are omitted below to clearly understand the correspondence between the mechanical structures. Fig. 3 is a top view of the switchable key in the first state. Fig. 4 to 6 are sectional views of the switchable key actuated in the first state. Fig. 7 is a top view of the switchable key in the second state. Fig. 8 to 10 are sectional views of the switchable key actuated in the second state. The stepping motor 9 receives the actuating signal, pushes the clip 21 to move in the assembling opening 15, and drives the movable shaft 30 to abut against the abutting portion 611 or move away from the abutting portion 611.

Referring to fig. 1 again, the mechanical keyboard 100 further includes a trigger button 71 and a circuit board 73, and the trigger button 71 and the circuit board 73 may be disposed in the housing 70 of the mechanical keyboard 100. The trigger button 71 and the stepping motor 9 are respectively connected to the circuit board 73, and when the trigger button 71 is pressed, the circuit board 73 generates an actuating signal and transmits the actuating signal to the stepping motor 9 to actuate the stepping motor 9 to start, so as to push the clip member 21 to translate in the assembly opening 15.

Here, the position of the switchable key 1 and the manner of generating the trigger are merely examples and are not intended to be limiting. For example, the stepping motor 9 may also directly receive an activation signal from a computer, or the trigger button 71 may be configured as a micro controller or mechanical press control, which directly generates a control signal.

As shown in fig. 3 to 6, in the first state of the switchable push button 1, the latch 21 is in the first position in the assembly opening 15, and at this time, the movable shaft 30 is away from the abutting portion 611, and when the mechanical shaft 61 is pressed and rebounded, the spring 45 is not affected. Therefore, in the first state, the switchable key 1 is restored only by the elasticity of the resilient element 63.

In addition, as shown in fig. 7 to 10, when the stepping motor 9 drives the clip 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 abutting against the abutting portion 611, so that the switchable key 1 is switched to the second state. At this time, when the mechanical shaft 61 is pressed, the mechanical shaft 61 drives the movable shaft 30 and the lever assembly 20 to move downward, and compresses the spring 45. In the second state, the switchable push button 1 is simultaneously subjected to the rebounding force of the rebounding element 63 and the rebounding force of the spring 45, so that the rebounding speed is increased, and the pressing touch feeling is changed.

Fig. 11 is a top view of a second embodiment of the mechanical keyboard of the present invention. Fig. 12 and 13 are perspective views of the switchable key of the second embodiment in the first state and the second state, respectively, and the difference from the previous embodiment is that the embodiment of fig. 11 has a plurality of switchable keys 1, a positioning plate 10, a shift lever assembly 20 and a stepping motor 9. In this embodiment, the mechanical keyboard 100 comprises a plurality of switchable keys 1. The difference from the previous embodiment is that the positioning plate 10 and the lever assembly 20 are used to drive the entire set of switchable keys 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 key 1 are substantially the same as those of the previous embodiment, and are not described again.

As shown in fig. 11 to 13, although not clearly shown in the perspective view, it can be understood by referring to the position of fig. 11 and referring to fig. 2, that the positioning plate 10 is provided with an assembly opening 15 and a plurality of key areas 10A, and each key area 10A includes a positioning opening 11 and a sliding opening 13. As shown in fig. 12 and 13, the lever assembly 20 includes a locking member 21, a linking member 27, and a plurality of triggering members 25. The clamping member 21 and the triggering member 25 extend along a normal direction of the linking member 27, the clamping member 21 is clamped in the assembling opening 15, and the triggering member 25 is located in the sliding opening 13 of the key area. The stepping motor 9 is connected to the linkage 27, receives the actuation signal, and pushes the clip 21 to move horizontally in the assembly opening 15, so as to drive each movable shaft 30 to abut against each abutting portion 611 or to move away from each abutting portion 611 through the linkage 27.

As shown in fig. 12, in this case, when the switchable key 1 is in the first state and all the movable shafts 30 are away from the abutting portion 611, the spring 45 is not affected when the single switchable key 1 is pressed and rebounded, as in the state of fig. 4 to 6.

As shown in fig. 13, the stepping motor 9 drives the trigger 25 and the movable shaft 30 to move integrally through the linking member 27, so that the movable shaft abuts against the abutting portion 611, and all the switchable keys 1 are switched to the second state. When the single switchable key 1 is pressed and rebounded, the state is the same as that of fig. 8 to 10.

In summary, the mechanical keyboard 100 can allow a user to selectively switch a specific key or a plurality of keys through the design of the switchable key 1, and can switch different use situations through the difference of touch feeling, and can also achieve the effects of avoiding erroneous touch and increasing efficiency.
