Specific embodiment
Below in conjunction with attached drawing, invention is further described in detail.
The embodiment of the invention discloses a kind of press-key structures, as depicted in figs. 1 and 2 comprising conductive film 1, positioned at leading
The bracket 2 of the top of conductive film 1, the movable button axle 3 for being plugged in bracket 2 and the keycap 4 set on the upper end of button axle 3, key
It is movable mating between cap 4 and button axle 3.The lower end of button axle 3 is equipped with spring contact 5, and bracket 2 is equipped with feel torsional spring
6, reset spring 7 is equipped between button axle 3 and bracket 2.When keycap 4 is in not by the free state of external force, spring contact 5
Bottom is higher than the bottom of bracket 2, i.e. spring contact 5 is packed up completely in bracket 2.When in use, by pressing keycap 4,
Keycap 4 drives button axle 3 mobile close to conductive film 1 downwards, and spring contact 5, which is moved to, squeezes corresponding touching on conductive film 1
Point 11, so that contact 11 is connected, during button axle 3 is mobile, feel torsional spring 6 and reset spring 7 are generated elasticity by pressure
Deformation, feel torsional spring 6 generate elastic deformation and make have mechanical feel, the elastic force that 7 elastic deformation of reset spring generates when key
For driving button axle 3 to move up reset.This press-key structure is different from thin film type keyboard press-key structure, has mechanical feel,
It is different from existing mechanical keyboard press-key structure simultaneously, under the free state not by external force, existing mechanical keyboard is pressed
Mobile central spindle (button axle 3 quite in this present embodiment) lower end of key in bond structure is below its pedestal and (is equivalent to this reality
Apply the bracket 2 in example) lower end, while the structure of this press-key structure is relatively easy, and cost is relatively low, while having when in use
There is mechanical feel.In addition, the key triggering stroke of this press-key structure is bigger, the key of this press-key structure triggering stroke be greater than or
Equal to 3.5mm.
As shown in Figures 2 and 3, bracket 2 is equipped with accommodating chamber 21,3 entirety of shapes and sizes and button axle of accommodating chamber 21
Shapes and sizes are adapted, and 3 mass activity formula of button axle is plugged in accommodating chamber 21, and can move up and down along accommodating chamber 21.Bracket 2
It is equipped with limited post 22 in the middle of accommodating chamber 21, the middle of limited post 22 offers perforative limit hole 221.Button axle 3
Equipped with positioning column 31, spring contact 5 is set to the lower end of positioning column 31, spring contact 5 and positioning column 31 be it is movable mating,
Positioning column 31 and spring contact 5 is movable is plugged in limit hole 221.When keycap 4 is in not by the free state of external force, elasticity touching
Part 5 is fully located in limit hole 221；When pressing keycap 4, button axle 3 is moved down along accommodating chamber 21, positioning column 31 and elasticity touching
Part 5 is moved down along limit hole 221, and limit hole 221 plays positioning and position-limiting action to positioning column 31, during effectively reducing key
Shaking.Bracket 2 is equipped with limiting slot 23 in two opposite side walls of accommodating chamber 21, and button axle 3 is equipped with limited block 32, limited block
32 slidings are in limiting slot 23.When pressing keycap 4 moves down button axle 3, limited block 32 is moved down along limiting slot 23.Limit
The cooperation of position block 32 and limiting slot 23 limits, and shaking when button axle 3 moves down in accommodating chamber 21 is further reduced, into one
Step is so that key stability is more preferable.The upper end of reset spring 7 is arranged and is fixed on positioning column 31, and lower end is set in limited post
22, the lower end of reset spring 7 can both be fixed on 21 bottom of accommodating chamber, and can also be not fixed only is contradicted with 21 bottom of accommodating chamber.It presses
When key axis 3 moves down, reset spring 7 is generated elastic deformation by the extruding of 21 bottom of accommodating chamber and button axle 3.
As shown in Figures 2 and 3, this press-key structure further includes limit base 8, and limit base 8 is fixed on the upper end of bracket 2,
Limit base 8 offers the through-hole 81 to match with button axle 3, and button axle 3 is movable to be plugged at through-hole 81.Button axle 3 and limit
Fit clearance between the through-hole 81 of position seat 8 levels off to as far as possible under the premise of meeting button axle 3 can move up and down
Zero, limit base 8 is further reduced shaking when button axle 3 moves down for playing position-limiting action to button axle 3.Limit base 8 is set
There are two opposite mounting rack 82, mounting rack 82 has installation limit plane 821, and the opposite side of the two of bracket 2 is equipped with peace
Spacing block set 24 is filled, after limit base 8 is mounted on bracket 2, installation limit plane 821 and the lower end surface for installing spacing block set 24
Inconsistent, the installation limit of spacing block set 24 is so that limit base 8 can not move up, so that relatively solid between limit base 8 and bracket 2
It is fixed.When needing to split limit base 8 and bracket 2, installation limit plane 821 can be made to be staggered with installation spacing block set 24 by tool
Afterwards, limit base 8 can be removed.Spacing block set 24 is installed and is equipped with supplemental slanted surface 241, the upper end of supplemental slanted surface 241 and limit base 8 it
Between horizontal distance be less than horizontal distance of the lower end between limit base 8 of supplemental slanted surface 241.Supplemental slanted surface 241 to limit
When 8 installation of seat is fixed, supplemental slanted surface 241 can push mounting rack 82 to generate certain deformation when pressing limit base 8, so that peace
Dress limit plane 821 and the lower end surface for installing spacing block set 24 are inconsistent.
As shown in Figures 2 and 3, bracket 2 is set there are two fixed fixture block 25 is installed, and the fixed fixture block 25 of two installations is located at
Two sides perpendicular with installation 24 place side of spacing block set of bracket 2, the fixed fixture block 25 of installation is used for and keyboard body
Cooperate by key mapping and limit, realizes that bracket 2 is mounted on keyboard body.Bracket 2 is that active installation is fixed on keyboard body
By in key mapping, in the correlated parts damage of press-key structure, the press-key structure of damage can be removed, be replaced.Installation is solid
Determine the cross section of fixture block 25 be it is trapezoidal, two inclined-planes for installing fixed fixture block 25 are located at both ends vertically and two inclined-planes are separate
2 end of bracket is wanted to draw close setting, so that bracket 2 can carry out auxiliary force by inclined-plane when mounting and dismounting.
This press-key structure can be not only used for the keyboard of high shaft type, it can also be used to the keyboard of low shaft type.This press-key structure is for height
When the keyboard of shaft type, whole free height is less than or equal to 17.8mm, and preferably 17.8mm, whole height is after pressing
17.1mm；When this press-key structure is used for the keyboard of low shaft type, whole free height is less than or equal to 11.9mm, preferably
11.9mm, whole height is 8.8mm after pressing.According to keyboard industry internal standard, the free height of the keyboard of high shaft type is greater than
Or it is equal to 17mm, the free height of the keyboard of low shaft type is less than or equal to 12mm.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
