Description
Technical field
The present invention relates to a kind of press-key structures, more particularly to the press-key structure with frivolous external form.
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 scissor connecting element.
The framework of the press-key structure in the keyboard for including scissor connecting element will be illustrated next.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, scissor connecting element 12, elasticity
Rubber bodies 13, film switch circuit 14 and bottom plate 15, and bottom plate 15 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 connecting bottom board 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.
With the development of science and technology, user increasingly requires the lightening of keyboard, keyboard manufacturer is dedicated to researching and developing
More frivolous press-key structure out, however, the press-key structure that manufacturer is developed is still limited by connection button cap and bottom plate
The connecting elements such as scissor connecting element structure, the limited extent that thickness reduces.Therefore, a kind of use is provided on the market
The press-key structure of soft-keys cap, wherein soft-keys cap is made by elastic rubber material.Such press-key structure is not provided with
Scissor connecting element, therefore its thickness can be reduced.
However, not set scissor connecting element causes new problem: soft-keys cap is easy to happen the feelings of unbalance stress
Condition.For example, when user presses the corner of soft-keys cap, since soft-keys cap is with soft elastic rubber material
Be made and not set scissor connecting element cause the support force of soft-keys cap insufficient, thus user be applied to it is soft by
The touch pressure of keycap can not be conducted by corner to entire soft-keys cap.In other words, user presses soft-keys cap, is easy to make
The case where push button signalling can not be generated at soft-keys cap unbalance stress, cause malfunction.
Frivolous external form can be had both therefore, it is necessary to one kind and avoids the press-key structure of malfunction.
Summary of the invention
