The present invention provides a cap structure suitable for being movably connected to a first support member and a second support member of a keyswitch. An end portion of the first support member is connected to the cap structure and has at least one shaft structure. The cap structure includes a cap body, a slot structure, and a limiting structure. The cap body has a bottom surface extending along an X-axis and a Y-axis. The X-axis, the Y-axis and a Z-axis are perpendicular to each other. The first support member and the second support member pivotably intersect with each other. The second support member is rotatably connected to the cap body and slidably connected to a board of the keyswitch, and the first support member is rotatably connected to the board, so as to make the cap structure movable upward and downward relative to the board. The slot structure protrudes from the bottom surface along the Z-axis and has a first slot corresponding to a first end of the at least one shaft structure along the X-axis for allowing the first end to be movably inserted into the first slot. The limiting structure protrudes from the bottom surface along the Z-axis to block movement of the at least one shaft structure along the Y-axis for limiting the first end in the first slot.

More detailed description for the sliding design of the cap structure 108 and the first support member 104 is provided as follows. As shown in
In such a manner, via the design of utilizing the first block 122 to block movement of the shaft structure 110 along the Y-axis and utilizing the second block 124 to block inward movement of the shaft structure 110 along the X-axis for increasing the pulling force between first support member 104 and the cap structure 108, the present invention can surely prevent the first end S1 of the shaft structure 110 from falling out of the first slot 120 accidentally when deformation of the cap structure 108 occurs (e.g. when the user pulls a corner of the cap structure 108 corresponding to the shaft structure 110) . As such, the shaft structure 110 can be limited between the slot structure 114 and the limiting structure 116 steadily, so as to efficiently solve the prior art problem that the cap is easy to fall off.
Furthermore, since the cap structure 108 only utilizes the limiting structure 116 to prevent the shaft structure 110 from falling off the first slot 120 without increasing a slot depth of the first slot 120 to enhance the pulling force between the first support member 104 and the cap structure 108, the slot depth of the first slot 120 can be further reduced (accordingly, the structural thickness of the slot structure 114 can be increased to enhance the pulling force between the first support member 104 and the cap structure 108), so that the user can press the shaft structure 110 of the first support member 104 vertically into the first slot 120 of the cap structure 108 effortlessly.
The sliding design of the cap structure and the first support member is not limited to the aforesaid embodiment. For example, please refer to
In such a manner, via the design of utilizing the second slot 158 to block movement of the shaft structure 110 along the Y-axis and utilizing the second block 160 to block inward movement of the shaft structure 110 along the X-axis for increasing the pulling force between first support member 104 and the cap structure 152, the present invention can surely prevent the shaft structure 110 from falling out of the first slot 120 and the second slot 158 accidentally when deformation of the cap structure 152 occurs (e.g. when the user pulls a corner of the cap structure 152 corresponding to the shaft structure 110) . As such, the shaft structure 110 can be limited between the slot structure 114 and the limiting structure 154 steadily, so as to efficiently solve the prior art problem that the cap is easy to fall off.
Moreover, since the cap structure 152 adopts the design of utilizing the first slot 120 and the second slot 158 to increase the pulling force between the first support member 104 and the cap structure 152 without adjusting the slot depth of the first slot 120, the slot depths of the first slot 120 and the second slot 158 can be further reduced (accordingly, the structural thickness of the slot structure 114 and the first block 156 can be increased for enhancing the pulling force between the first support member 104 and the cap structure 152) , so that the user can press the shaft structure 110 of the first support member 104 vertically into the first slot 120 and the second slot 158 of the cap structure 152 effortlessly.
To be noted, the sliding design of the slot of the slot structure and the shaft end of the shaft structure adopted by the present invention is not limited to the aforesaid embodiments, meaning that the present invention could adopt the design that the slot and the shaft end swap their positions. For example, please refer to

More detailed description for the sliding design of the cap structure 206 and the first support member 202 is provided as follows, and the related description for the sliding design of the cap structure 206 and the second support member 204 could be reasoned by analogy according to the following description. As shown in
To be more specific, in this embodiment, the limiting structure 210 has an avoiding surface 212 facing a second end S6 of the shaft structure 208. The avoiding surface 212 matches with the second end S6 along a motion track of the first support member 202, so as to make the cap structure 206 spaced apart from the second end S6 at a predetermined gap D when the cap structure 206 moves upward and downward relative to the board 102. The predetermined gap D could be preferably between 0.02 mm and 0.05 mm or between 0.05 mm and 0.15 mm (but not limited thereto). Accordingly, during upward and downward movement of the cap structure 206, the limiting structure 210 can be spaced apart from the first support member 202 for improving motion smoothness of the cap structure 206, meaning that the aforesaid gap can inhibit or prevent abrasion between the cap structure 206 and the first support member 202. As for the other related description for the keyswitch 200, it could be reasoned by analogy according to the aforesaid embodiments and omitted herein.
It should be mentioned that the connection design of the cap structure and the first support member is not limited to the aforesaid sliding designs, meaning that the present invention could adopt the pivotal connection design in another embodiment. For example, please refer to
