As shown in fig. 1, 2, and 3, the key 10 includes a base plate 12, a key cap structure 14, a lifting mechanism 16, a spring 18, and a snap ring 20. The lifting mechanism 16 is detachably connected to the base plate 12 and the key cap structure 14, whereby the key cap structure 14 can move up and down relative to the base plate 12 via the lifting mechanism 16.
In terms of the connection design between the key cap structure 14 and the spring 18 and the fastening ring 20, as shown in fig. 2 and 3, the key cap structure 14 has at least one fixing hook 22 (three are shown in fig. 2, but not limited thereto) and at least one limit stop 54, the spring 18 is hooked on the limit stop 54 and abuts against the bottom plate 12 to drive the key cap structure 14 to move away from the bottom plate 12, and the fastening ring 20 is detachably fastened to the fixing hook 22 to clamp the spring 18 together with the limit stop 54 on the key cap structure 14. In this embodiment, the key cap structure 14 may comprise a key cap engaging member 24, a key cap main body member 26, and a spring fixing base 28, the lifting mechanism 16 is preferably configured by a scissor leg supporting mechanism commonly used on keyboard keys (but not limited thereto, and may also be configured by other common key lifting supporting mechanisms, such as a magnetically attracted key mechanism, etc.) and is detachably connected to the key cap engaging member 24, for example, as shown in fig. 3, the key cap engaging member 24 may have a chute 30 and a slot 32, the lifting mechanism 16 may comprise a first supporting member 34 and a second supporting member 36, the first supporting member 34 and the second supporting member 36 are cross-pivoted, the first supporting member 34 has a sliding portion 38 and is rotatably connected to the bottom plate 12, the sliding portion 38 is slidably connected in the chute 30, and the second supporting member 36 has a pivoting portion 40 and is slidably connected to the bottom plate 12, and the pivoting portion 40 is rotatably connected to the slot 32, whereby the sliding movement of the first supporting member 34 relative to the key cap engaging member 24 and the second supporting member 36 relative to the bottom plate 12 and the lower key cap 24 and the lower key cap engaging member 24 relative to the bottom plate 12 can move relative to the bottom plate 12.
In practical applications, to enhance the convenience of assembly and disassembly, the key cap engaging member 24 is preferably detachably engaged under the key cap main body member 26 by a magnetic attraction design. In this embodiment, as can be seen from fig. 2, the key cap engaging member 24 may have a first magnetic member 42, and the key cap main body member 26 has a second magnetic member 44 corresponding to the first magnetic member 42, so that the first magnetic member 42 can magnetically attract the second magnetic member 44 to detachably engage the key cap engaging member 24 under the key cap main body member 26. Further, at least one side edge S of the key cap engaging member 24 may be formed with at least one first positioning structure 46 (preferably, but not limited to, a protruding slope structure is adopted), for example, as shown in fig. 2, one first positioning structure 46 may be formed on each of the side edges S of the key cap engaging member 24 on the left and right sides, two first positioning structures 46 (but not limited to) may be formed on each of the side edges S of the key cap engaging member 24 on the rear side, and a corresponding second positioning structure 48 (preferably, but not limited to, a protruding rib structure is adopted) may be formed at a position of the key cap main body member 26 corresponding to the first positioning structure 46, so that the first positioning structure 46 may be engaged with the second positioning structure 48 to enable the key cap engaging member 24 to be more firmly engaged under the key cap main body member 26. It should be noted that, as shown in fig. 2, in this embodiment, the side edge of the key cap main body 26 of the key cap structure 14 corresponding to the second magnetic member 44 may be preferably formed with a recess structure 27, so that a user can pull the key cap structure 14 via the recess structure 27 to perform a subsequent disassembling operation of the key cap structure 14.
In addition, as shown in fig. 2 and 3, in this embodiment, the through hole 50 may be formed at the position of the key cap joint member 24 corresponding to the spring 18, the spring fixing base 28 may be formed with the fixing hook 22 and connected to the position of the key cap main body member 26 corresponding to the through hole 50 (for example, the spring fixing base 28 may be attached under the key cap main body member 26 by using the adhesive layer 52 shown in fig. 2, but not limited thereto, other conventional connection designs, such as a structure snap design, etc.), so that the fastening ring 20 may be detachably fastened to the fixing hook 22 to clamp the spring 18 together with the spring fixing base 28 (as shown in fig. 3). Further, as shown in fig. 2, at least one limit stop 54 (three are shown in fig. 2, but not limited thereto) may be formed on the spring holder 28, and the limit stop 54 may laterally abut the spring 18 and be disposed in an annular arrangement with the fixing hook 22, such that the spring 18 may be more accurately positioned to the spring holder 28. Preferably, at least one of the limit stops 54 has a snap-hook structure thereon to more accurately position the spring 18 in a vertical direction to the key cap structure.
With the above design, after the key cap main body 26 with the spring 18 connected thereto and the key cap engaging member 24 connected to the lifting mechanism 16 are assembled (as shown in fig. 3), the key 10 can provide a linear pressing feeling without a feeling of falling by utilizing the linear deformation characteristic of the spring 18 during the process of pressing the key cap structure 14 by a user. As for the related description of the switch triggering design of the key 10 (such as the optical triggering design for detecting the pressing stroke of the key cap structure 14 by the optical sensor or the contact triggering design for pressing the trigger switch of the circuit board by the lifting mechanism 16), it is common in the prior art and will not be described herein.
Therefore, the step of sequentially positioning and connecting the spring and the key cap to the lifting mechanism of the key is omitted by directly fixing the spring to the key cap structure by the fastening ring, so that a user can complete the key assembly process after only assembling the key cap structure fixed with the spring to the lifting mechanism, the problem that the assembly and positioning process of the key cap and the elastic piece in the prior art is time-consuming and labor-consuming is effectively solved, and the convenience of assembling and disassembling the key is greatly improved.
It should be noted that the key cap structure provided by the present invention may not be limited to the three-piece detachable design mentioned in the above embodiment, for example, in another embodiment, the key cap engaging member 24 and the spring fixing base 28 may be integrally formed directly on the key cap main body member 26 to form a single key cap structure together, so as to simplify the key cap structure design of the present invention (the bonding structure between the components originally used for the integral forming may be omitted, for example, the first positioning structure 46 and the second positioning structure 48, the adhesive layer 52, etc.), as for other derivative variant embodiments (for example, only the design that the spring fixing base 28 is integrally formed on the key cap main body member, or only the design that the key cap engaging member 24 is integrally formed on the key cap main body member), which will not be repeated herein.
In addition, the key 10 of the present invention can further provide a function of changing the pressing feeling, for example, referring to fig. 3, 4, and 5, fig. 4 is a schematic perspective view of the connection of the paragraph sense elastomer 56 to the replacement key cap structure 58, and fig. 5 is a schematic cross-sectional view of the connection of the paragraph sense elastomer 56 and the replacement key cap structure 58 of fig. 4 to the lifting mechanism 16. As shown in fig. 4 and 5, the present invention provides a key assembly, which includes a segment-sensitive elastomer 56 and a replacement key cap structure 58, wherein one end of the segment-sensitive elastomer 56 is connected to the replacement key cap structure 58 (for example, but not limited to, by an adhesive bonding method). With the above design, when the user wants to switch the key 10 to provide a pressing feeling with a feeling of a paragraph, the user only needs to use the adjusting tool or the pliers tool to detach the spring 18 from the lifting mechanism 16 along with the key cap structure 14, and then assemble the replacement key cap structure 58 with the paragraph feeling elastomer 56 connected thereto to the lifting mechanism 16 (as shown in fig. 5), so that the key 10 can provide a pressing feeling with a feeling of a paragraph feeling with the paragraph feeling elastomer 56 in the process of pressing the replacement key cap structure 58 by the user. It should be noted that the above-mentioned design related to the key cap removing of the key cap main body and the key cap engaging member or the design of the single key cap structure can be applied to the replacement key cap structure 58, and the description thereof can be analogized with reference to the above description, which is not repeated herein, and what design is adopted depends on the practical application requirement of the key 10.
