Description
The utility model relates to a kind of button, the keyboard that particularly relates to a kind of shear-type key and comprise this button.
Keyboard is applied in various equipment or equipment at large, and computing machine for example is in order to input characters or numeral.
And the button on the keyboard, for the balance user by the application of force on each button, even the application of force is at the side or the side of button, also the application of force can be dispersed in fifty-fifty on the whole button face, press whole button easilier, allow the easy operation push-button of user, therefore, below the cap of button, generally can design a kind of scissor structure.The keyboard that the mancarried device of strict requirement for restriction is particularly arranged for the space, for example ultrathin notebook, the button height can not be too high, often needs especially to use the scissor structure of this kind in order to operation.
On the other hand, for some button, particularly has button than long side, for example blank key or shift key are for balance is applied to the strength of long side two ends, even make that the button application of force is at two ends, also can press whole button, usually under cap a kind of balance stem can be set, the application of force of coming balance two ends increases the convenience of operation fifty-fifty whole button is pressed.
The prior art button is in conjunction with above-mentioned scissor construction and balance stem the time, and in the scissor construction outside of a support arm wherein, this support arm is separated from each other, is not connected mutually with balance stem with balance bar device.
As shown in Figures 1 and 2, the scissor structure button of prior art that it comprises balance stem shows backplan and side view respectively.
Existing shear-type key structure generally comprises a base, a keycap, a scissor construction, a flexible member and a switch element, also comprise a balance stem being provided with of long key, and being set to of flexible member and switch element is existing, does not repeat them here.The shortcoming of prior art button 10 is, is positioned at the scissor construction 2 of cap below 1 and must sacrifices one apart from d, for yielding to balance stem 3 is set, and can dwindles the entire area of the scissor construction 2 balance application of forces like this; Particularly, be positioned at the second end 22 of a support arm 2a of scissor construction 2, must shrink back, to move between clearancen for balance stem 3 is set apart from d.So, will be unfavorable for that scissor construction 2 is scattered in whole cap 1 with the application of force.In addition and since the wherein support arm 2a of scissor construction 2 must shrink back one apart from d for balance stem 3 is set, and the stroke of shear mechanism is again fixed range, so can't effectively reduce the height of button 10.Such shortcoming is unfavorable for producing ultrathin device.
At the shortcoming of above-mentioned prior art, be necessary to provide a scheme, addressing the above problem, and provide better button and keyboard.
The purpose of this utility model is to provide a kind of button, and it can solve because the problem that scissor construction that balance stem causes dwindles and the button height can't further reduce is set.
The purpose of this utility model is achieved in that promptly provides a kind of shear-type key, comprising: a base; One keycap is located on this base; One balance stem is arranged between this keycap and this base, and this balance stem comprises one first end and one second end, and first end is connected in this keycap, and this second end is connected in this base; An and scissor construction, be arranged between this base and this keycap, this scissor construction comprises a first end, one the second end, one the 3rd end and one the 4th end, this first end is connected in this keycap, and this second end is connected in first end of this balance stem, and the 3rd and the 4th end is connected in this base.Wherein, by this scissor construction and this balance stem, this keycap this base is relatively done the oscilaltion campaign.
The utility model also provides a kind of shear-type key, comprising: a base; One keycap is arranged on this base; One balance stem is arranged between this keycap and this base, and this balance stem comprises one first end and second end, and this second end is connected in this base; An and scissor construction, be arranged between this base and this keycap, this scissor construction comprises a first end, one the second end, one the 3rd end and one the 4th end, this first end and this second end are connected in this keycap, and the 3rd and the 4th end is connected in this base, and this keycap is done the oscilaltion campaign with respect to this base thus; Wherein, first end of this balance stem is connected with this second end.
In a preferred embodiment more, the second end is connected in keycap.
Preferable, the second end also comprises a holding part, seizes balance stem on both sides by the arms and is connected with the formation of the second end to reach balance stem.
The advantage of the utility model device is, it is connected by balance stem is constituted with the second end of scissor construction, make scissor construction not need to shrink back a segment distance for balance stem is set, the height that so can reach peak use rate on the space, button is minimized and makes that the operation of button is more convenient.
