However, the number of the pressing members 5, the keycaps 6, and the scissor foot modules 7 can be adjusted to one as needed, and is not limited to this embodiment. In order to briefly introduce the structure of the embodiment, the following description will take one of the pressing members 5, the keycaps 6, and the scissor foot modules 7 as an example for explanation where not specifically described.

[0028] See Figures 3 to 5 The base plate 1 includes a base plate body 11 and a plurality of support and limiting portions 12 connected to the top side of the base plate body 11. The base plate body 11 defines a lower adjustment hole 111.

[0029] The top plate 2 includes a top plate body 21 and a plurality of lower pivoting portions 22 extending upward from the top plate body 21. The top plate body 21 contacts the support stop 12 and defines a through hole 211 and an upper adjustment hole 212 corresponding in position to the lower adjustment hole 111. The top plate body 21 and the bottom plate body 11 jointly define a displacement space P1.

[0030] The adjustment module 3 includes a middle plate body 31 movably disposed in the displacement space P1, a receiving seat 32 fixedly connected to the top side of the middle plate body 31 and extending through the through hole 211, and a torsion elastic member 33 disposed within the receiving seat 32. It is worth noting that in variations of this embodiment, the number of the receiving seats 32 and the torsion elastic members 33 can be adjusted as needed and is not limited thereto.

[0031] The middle plate body 31 defines a plurality of stopper openings 311 for the support stopper 12 to pass through, three protruding holes 312, and an adjustment portion 313. The adjustment portion 313 is exposed through the upper adjustment hole 212 and the lower adjustment hole 111 and is configured to be driven by the adjustment column 9.

[0032] The receiving seat 32 has a receiving body 321 and three protrusions 322 connected to the receiving body 321 and respectively passing through the protrusion holes 312 to contact the bottom plate body 11. It is worth mentioning that the number of the protrusions 322 can be adjusted as needed and is not limited thereto.

[0033] The torsion elastic member 33 includes a torsion body 331 confined within the accommodating seat 32, and a deflection portion 332 connected to the torsion body 331. When the deflection portion 332 is compressed, torsion is stored in the torsion body 331. In this embodiment, the torsion elastic member 33 is a torsion spring.

[0034] The sensing module 4 is disposed on the top side of the top plate body 21 and below the keycap 6. It defines a plurality of pivot holes 41 through which the lower pivot portion 22 passes, and an auxiliary adjustment hole 42 corresponding to the lower adjustment hole 111 and the upper adjustment hole 212. The sensing module 4 is used to sense the pressure applied to the keycap 6. In this embodiment, the sensing module 4 is a sensing film.

[0035] The pressing member 5 is disposed on the top side of the top plate body 21 and below the keycap 6. The pressing member 5 is used to provide support for the keycap 6. In this embodiment, the pressing member 5 is a rubber cover.

[0036] The keycap 6 is located above the top plate 2 and the accommodating seat 32 and includes an outer side surface 61 , an inner side surface 62 opposite to the outer side surface 61 and contacting the top side of the pressing member 5 , and four upper pivot portions 63 connected to the inner side surface 62 .

[0037] The scissor leg module 7 is rotatably disposed between the upper pivot portion 63 and the lower pivot portion 22 and surrounds the pressing member 5. The scissor leg module 7 includes a first bracket 71 and a second bracket 72 pivotally connected to each other.

[0038] The first bracket 71 includes a first frame member 711 and a pressing block 715 fixed to the first frame member 711 and positioned corresponding to the deflection portion 332. In this embodiment, the second bracket 72 surrounds the first bracket 71 and is arranged in a cross pattern. The first frame member 711 includes a first frame body 712, two first upper pivot rods 713 connected to the first frame body 712 and spaced apart along a left-right direction D1, and two first lower pivot rods 714 connected to the first frame body 712 and spaced apart along the left-right direction D1. The first upper pivot rods 713 are rotatably mounted on two of the upper pivoting portions 63, and the first lower pivot rods 714 are rotatably mounted on two of the lower pivoting portions 22. The pressing block 715 is connected to the first frame body 712 and is located between the first upper pivot rods 713.

[0039] The second bracket 72 includes a second frame member 721, which includes a second frame body 722, two second upper pivot rods 723 connected to the second frame body 722 and spaced apart along the left-right direction D1, and two second lower pivot rods 724 connected to the second frame body 722 and spaced apart along the left-right direction D1. The second upper pivot rods 723 are rotatably mounted on the other two portions of the upper pivoting portion 63, and the second lower pivot rods 724 are rotatably mounted on the other two portions of the lower pivoting portion 22. In this embodiment, the second upper pivot rods 723 are integrally formed.

[0040] During actual operation, the middle plate body 31 is pre-set to switch between a first pressure-sensing position and a second pressure-sensing position relative to the displacement space P1. More specifically, the middle plate body 31 is slidably positioned relative to the support stopper 12 via the limit openings 311, allowing it to switch between the first and second pressure-sensing positions relative to the displacement space P1 along a front-to-back direction D2 perpendicular to the left-to-right direction D1.

[0041] See Figure 4 The adjusting column 9 drives the middle plate body 31 to move forward relative to the displacement space P1 to the first pressure-sensing position, and the deflection portion 332 of the torsion elastic member 33 is located away from the scissor leg module 7 along the front-to-back direction D2 relative to the displacement space P1 and is located in front of the pressing block 715.

[0042] See Figures 5 to 7 , the middle plate body 31 moves to the first pressure-sensing position. While the keycap 6 is being pressed, the deflection portion 332 is outside the movement range of the pressing block 715 and does not interfere with the pressing block 715. Therefore, during this period, only the pressing member 5 provides support force, providing the first pressing feel.

[0043] See Figure 8 The adjusting column 9 drives the middle plate body 31 to move rearward relative to the displacement space P1 to the second pressure-sensing position, and the deflection portion 332 of the torsion elastic member 33 is located closer to the scissor leg module 7 along the front-to-back direction D2 relative to the displacement space P1 and is located below the pressure block 715.

[0044] See Figures 9 to 11, the middle plate body 31 moves to the second pressure-sensing position. While the keycap 6 is being pressed, the deflection portion 332 is within the travel of the pressing block 715 and can be pressed by the pressing block 715. Therefore, during this period, the torsion elastic member 33 and the pressing member 5 jointly provide support force, providing a second, more resilient pressing feel that is different from the first.

[0045] Therefore, the keyboard device with a pressure-sensing switching function of the present invention pre-adjusts the position of the middle plate body 31 relative to the displacement space P1 along the front-to-back direction D2. When the middle plate body 31 is adjusted to the first pressure-sensing position, the deflection portion 332 is outside the moving range of the pressure block 715, and the supporting force is only provided by the pressing member 5. When the middle plate body 31 is adjusted to the second pressure-sensing position, the deflection portion 332 is within the moving range of the pressure block 715, and the supporting force is jointly provided by the torsion elastic member 33 and the pressing member 5, thereby having the effect of providing two different pressing feels.

[0046] In summary, the keyboard device with pressure-sensing switching function of the present invention can indeed achieve the purpose of the present invention.

[0047] The above descriptions are merely embodiments of the present invention and should not be used to limit the scope of the present invention. In other words, any simple equivalent changes and modifications made according to the claims and description of the present invention still fall within the scope of the present invention.
