As shown in Figure 4 and Figure 5, when the user presses the keycap 32 of the button 2, the lifting support mechanism 34 drives the keycap 32 to approach the bottom plate 30 along the descending direction X1 shown in Figure 4, at this time the pivot connection of the connecting member 36 The portion 363 pivots relative to the pivot structure 42 , and the sliding slot structure 40 restricts the sliding portion 361 of the connecting member 36 to slide along the deformation direction Y2 . In this way, the keycap 32 can be moved from the reset position as shown in FIG. 4 to the pressing position as shown in FIG. The function that the user wants to input. It is worth mentioning that when the keycap 32 is pressed, the sliding portion 361 of the connecting member 36 compresses the elastic member 38 along the deformation direction Y2 so that the elastic member 38 stores elastic potential energy.

Furthermore, when the user completes the desired input function, the user no longer presses the key cap 32 of the key 2, and at this moment the elastic member 38 can release the elastic potential energy to generate an elastic restoring force along the reset direction Y1, thereby driving The sliding portion 361 of the connecting member 36 slides in the sliding groove structure 40 along the reset direction Y1, and makes the connecting member 36 pivot relative to the pivoting portion 363 .

It can be seen from experiments that the size of the angle θ is related to the peak force (peak force) produced by the button 2 during the pressing process. time is positively correlated. That is to say, when the angle θ is larger, the force feedback peak of the button 2 occurs earlier during the pressing process; on the contrary, when the angle θ is smaller, the force feedback peak of the button 2 occurs later during the pressing process. It is worth mentioning that the angle θ cannot be equal to ninety degrees, that is, the connecting member 36 is not perpendicular to the bottom plate 30 and the keycap 32 in design, so as to prevent the pivoting portion 363 of the connecting member 36 from being unable to pivot when the button 2 is pressed. Turn and the sliding part 361 cannot slide and cause the situation that the button 2 is stuck.

The above-mentioned structural design is simple in structure and small in size and does not occupy the volume of the key in the height direction, so the present invention helps to reduce the overall height of the key, thereby facilitating the development trend of thinning the keyboard.

The present invention has been described by the above-mentioned related embodiments, however, the above-mentioned embodiments are only examples for implementing the present invention. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, changes and modifications made without departing from the spirit and scope of the present invention all belong to the scope of patent protection of the present invention.
