Description
Technical field
The present invention relates to a kind of input units, more particularly to include the keyboard of multiple press-key structures.
Background technique
Common computer peripheral input unit includes mouse, keyboard and trace ball etc., and wherein keyboard can directly key in text
Word and symbol give computer, therefore the attention quite by user and input unit manufacturer.Wherein, relatively conventional is one
Kind includes the keyboard of multiple press-key structures.
The framework that the press-key structure in keyboard will be illustrated next, for including the press-key structure of scissor connecting element
Explanation.Referring to Fig. 1, it is the diagrammatic cross-sectional side elevation of existing press-key structure.Existing press-key structure 1 includes button cap 11, cuts
Blade connecting element 12, elastic rubbery body 13, film switch circuit 14 and bottom plate 15, and bottom plate 15 is to carry button cap
11, scissor connecting element 12, elastic rubbery body 13 and film switch circuit 14.Wherein scissor connecting element 12 is to even
Connect bottom plate 15 and button cap 11.
Scissor connecting element 12 is between bottom plate 15 and button cap 11 and is separately connected the two.Scissor connection member
Part 12 includes the first frame 121 and the second frame 122.The first end of first frame 121 is connected to button cap 11, and the first frame
The second end of frame 121 is then connected to bottom plate 15.Elastic rubbery body 13 is surround by scissor connecting element 12, and film switch circuit
14 have multiple press-button contacts (not shown in the figures).The press-button contact exports corresponding push button signalling when being triggered.Bullet
Property rubber bodies 13 be set on film switch circuit 14 and elastic rubbery body 13 corresponds to a press-button contact, when elastic rubber
When colloid 13 is touched, deformation occurs and presses corresponding press-button contact in film switch circuit 14 and produces for elastic rubbery body 13
Raw push button signalling.
The operation situation that existing press-key structure 1 is pressed by user will be illustrated next.In Fig. 1, when user presses key
When cap 11,11 stress of button cap and pushing against scissor connecting element 12 makes its movement, therefore button cap 11 can be past relative to bottom plate 15
Lower movement and press corresponding elastic rubbery body 13.At this point, deformation occurs and presses film switch circuit for elastic rubbery body 13
14 to trigger the press-button contact of film switch circuit 14, so that film switch circuit 14 exports corresponding push button signalling.And work as
User stops when pressing button cap 11, the no longer stress of button cap 11 and stop pressing elastic rubbery body 13 so that elastic rubber
Body 13 restores to the original state in response to its elasticity, while providing elastic restoring force up, therefore button cap 11 is pushed back touched
Position before.Above-mentioned structure and operation situation for existing press-key structure.
However, during button cap 11 is touched, the situation that scissor connecting element 12 can inevitably rock,
The shaking of entire press-key structure 1 will be caused, to influence the running stability of keyboard.Running can be promoted therefore, it is necessary to one kind to stablize
The keyboard of degree.

Signal.During connecting element 23 is swung, the shape of 2522 arc strip of protrusion is contacted, connecting shaft 25 can be assisted swimmingly to turn
It is dynamic, and contact plane 2523 can then be contacted with switching circuit board 22, and the supporting point of connecting element 23 is formed, make connecting element 23
It can steadily swing, to promote the running stability of button cap 20.And when user no longer presses button cap 20, button cap 20
Generated elastic force can be restored by deformed state in response to elastic element 24 and up be moved relative to bottom plate 21, to push against key
Cap 20 up moves, while driving connecting element 23 to swing and reverting to folding condition by closed state, and the meeting of button cap 20 is extensive
The multiple position to before being touched.
Specifically, although this preferred embodiment only discloses the structure that connecting shaft is set on the first frame,
Connecting shaft is set to the structure on the side wall of the second frame also without departing from spirit disclosed in keyboard of the present invention, and also belongs to this hair
The claims of bright keyboard.
In addition, the present invention also provides from the second preferred embodiment of the above-mentioned different practices.Referring to Fig. 5, it is the present invention
Partial structural diagram of the keyboard in the second preferred embodiment.Keyboard 3 of the present invention includes that multiple button caps (are not depicted in figure
In), bottom plate 31, switching circuit board 32, multiple connecting elements 33 (one is only shown in figure), multiple elastic elements (be not depicted in
In figure), multiple connecting shafts 35 (one is only shown in figure) and diaphragm 36.Connecting element 33 include the first frame 331 and
Second frame 332, and connecting shaft 35 is set on the side wall 3311 of corresponding first frame 331 comprising main shaft 351 with
And outrigger shaft 352.The structure of keyboard 3 in this preferred embodiment is generally identical as the keyboard 2 in aforementioned preferred embodiment, and
Something in common repeats no more.And the rwo the difference is that, diaphragm 36 is provided in keyboard 3.
In Fig. 5, diaphragm 36 corresponds to connecting shaft 35 and is set on switching circuit board 32, is located at connecting shaft 35 and opens
It closes between circuit board 32.That is, the main shaft 351 of connecting shaft 35 can be contacted with bottom plate 31, and outrigger shaft 352 then with film
Piece 36 contacts.Diaphragm 36 can provide defencive function, contacts and occurs with connecting shaft 35 to avoid 32 long-time of switching circuit board
The situation of abrasion.In this preferred embodiment, diaphragm 36 is the plastic slice that size is slightly larger than connecting shaft 35, is only to illustrate
It is used, rather than as limit.In another preferred embodiment, diaphragm also be can be used with switching circuit board with size or any ruler
Very little plastic slice.In addition, the operation situation of the keyboard 3 of this preferred embodiment and aforementioned preferred embodiment are similarly, thus it is no longer superfluous
It states.
As described above, keyboard of the present invention is in being arranged connecting shaft in connecting element, so that connecting shaft can simultaneously and bottom plate
And switching circuit board (or diaphragm) contact.In response to the local shape of connecting shaft, the swing of connecting element can be assisted, meanwhile,
Connecting shaft can contact and be formed the supporting point of connecting element with switching circuit board (or diaphragm), put connecting element can steadily
It is dynamic, to promote the running stability of key.
The foregoing is merely presently preferred embodiments of the present invention, the claim being not intended to limit the invention, thus it is all its
It is intended to be limited solely by the claim of this case without departing from the lower equivalent change or modification completed of spirit disclosed in this invention
It is interior.
