These switches 14 are fixed on this substrate 12, and this keycap 16 limits a lower surface 162, and this lower surface 162 convexes with two protuberances 164, one of correspond to respectively in these switches 14.18 of this bracing or strutting arrangements can be in order to supporting the vertical moving that this keycap 16 is done with respect to this substrate 12, and this bracing or strutting arrangement 18 corresponds to one of them switch 14.When this keycap 16 was pressed, these protuberances 164 and/or this bracing or strutting arrangement 18 can trigger at least one switch in these switches 14.
In this specific embodiment, aforesaid bracing or strutting arrangement 18 comprises a scissors kenel supporting member 182 and an elastic component (elastic device) 184.The last junction of this scissors kenel supporting member 182 engages with the lower surface 162 of this keycap 16, and junction then engages with this substrate 12 under it.In addition, the lower surface 162 of this keycap 16 of last end in contact of this elastic component 184, its lower end then contacts this switch 14.When this keycap 16 was pressed, this scissors kenel supporting member 182 can support the vertical moving that this keycap 16 is done with respect to this substrate 12, and this elastic component 182 then can trigger this switch 14.
In actual applications, when button of the present utility model is the long multiple button of length, as blank key, SHIFT key; Or the button with abnormal shape (non-square) outward appearance, as the ENTER key, the time, it further comprises a balance component (balance device).This balance component has an axial region, and limits one first end and with respect to one second end of this first end.This axial region extends a first side from this first end with one first angle bending, and this second end extends a second side with one second angle bending certainly.Further, this axial region is fixed in the lower surface of this keycap and this first side and this second side and is articulated in one first Pivot component and one second Pivot component on this substrate respectively.When this keycap 16 was pressed, this balance component can be made vertical moving with respect to substrate with scissors kenel supporting member together support keycap, and can drive the action of keycap more completely.
In actual applications, keycap of the present utility model is to make with plastic material.But note that keycap of the present utility model also can be made by other suitable materials, be not limited to plastic material.
Another preferred embodiment of the present utility model then provides a kind of keyboard (keyboard) that comprises aforementioned keys.This keyboard comprises a substrate, is fixed in a plurality of switches on this substrate, a plurality of keycap and a plurality of bracing or strutting arrangement.
Each keycap in these keycaps all limits a lower surface, and one first keycap in these keycaps corresponds to N first switch in these switches, and the lower surface of this first keycap convexes with M protuberance, one of correspond to respectively in this N first switch, N is greater than a positive integer of 1, and M is more than or equal to 1 and less than the positive integer of N.These bracing or strutting arrangements one of then correspond to respectively in these keycaps and these switches in one of, make vertical moving in order to support these keycaps with respect to this substrate.Especially, at least one bracing or strutting arrangement in these bracing or strutting arrangements one of corresponds to respectively in this N first switch.When pushing this first keycap, this M protuberance and/or this at least one bracing or strutting arrangement can trigger this N at least one first switch in first switch.
For example, aforesaid first keycap can correspond to five first switches, and has wherein three first switches of three protuberance correspondences, and two other first switch is then by two bracing or strutting arrangement correspondences.
In actual applications, these bracing or strutting arrangements comprise scissors kenel supporting member and elastic component.The last junction of this scissors kenel supporting member and the lower surface engages of keycap, junction then engages with substrate under it.In addition, the lower surface of the upper end of this elastic component contact keycap, its lower end is contact-making switch then.When this keycap was pressed, this scissors kenel supporting member can support the vertical moving of this keycap work with respect to substrate, and this elastic component then can trigger switch.
As previously mentioned, when aforesaid first keycap is the long multiple button of length, as blank key, SHIFT key; Or the button with abnormal shape (non-square) outward appearance, during as the keycap of ENTER key, this keyboard can further comprise a balance component.This balance component has an axial region, and limits one first end and with respect to one second end of this first end.This axial region extends a first side from this first end with one first angle bending, and this second end extends a second side with one second angle bending certainly.Further, this axial region is fixed in the lower surface of this first keycap and this first side and this second side and is articulated in one first Pivot component and one second Pivot component on this substrate respectively.When first keycap was pressed, this balance component can be made vertical moving with respect to substrate with scissors kenel supporting member together support first keycap, and can drive the action of first keycap more completely.
In actual applications, aforesaid first keycap is to make with plastic material.But note that this first keycap also can be made by other suitable materials, be not limited to plastic material.In addition, other keycaps outside first keycap also can be to make with plastic material or other suitable materials.
In sum, correspond to a plurality of switches owing to of the present utility model by bond energy, and the keycap lower surface of this button has a plurality of protuberances and corresponds to these switches, and therefore, no matter at least one switch in these a plurality of switches all can effectively be triggered in user any position of pushing this keycap.
