Slabstone etc..The protection to touch sensing 32 may be implemented in touch cover 33, and does not influence the sensitivity of touch sensing 32.
Touch sensing 32 is close to the setting of touch cover lower surface, it can be ensured that the stabilization of the touching signals acquired and accurate so that touches
Control cover board 33 does not influence the sensitivity of touch sensing 32.
Pedestal 31 includes substrate 311 and basic ring 312, and basic ring 312 is arranged along a circumferential edges protrusion of substrate 311, touch-control lid
Plate 33 fastens the top open part mounted on basic ring 312, to facilitate pedestal 31 and touch cover 33 and touch sensing 32 it
Between assembly connection so that touch control component 3 formed an entirety module, to facilitate the connection between other component.Herein, exist
In other embodiment, pedestal may be tabular, and the periphery of touch cover is buckled to towards flange, touch cover is bent to form
On pedestal, so as to form accommodating chamber between pedestal and touch cover.
Preferably, touch sensing 32 is capacitance sensor, to improve sensitivity, the dynamic response of touch signal induction
Speed and stability.Herein, in other implementations, touch sensing 32 may be electric resistance sensor or other can
Detect the sensor of touch signal.The upper surface of touch sensing 32 is viscous by the first fixed double-sided glue 35 and touch cover 33
Gu so that touch sensing 32 is close to be arranged with the lower surface of touch cover 33, avoid occurring gap therebetween, into one
Step ensures the stabilization of acquired capacitance signal and accurate.The lower surface of touch sensing 32 by the second fixed double-sided glue 36 with
311 cementation of substrate, to facilitate being fixedly connected between capacitance sensor and its touch cover 33 and substrate 311.
The material of pedestal 31 is metal material, to improve structural strength.Pedestal 31 can be integrally formed, such as pass through punching
Pressure mode is formed, in order to machine-shaping.When pedestal 31 is metal material, to avoid generating the electrostatic to touch sensing 32
Interference, needs pedestal 31 being electrically connected with touch sensing 32, therefore touch sensing 32 passes through 36 cementation of the second fixed double-sided glue
In pedestal 31, the second fixed double-sided glue 36 is conductive double sided adhesive tape, and touch sensing 32 is connected with flexible PCB (FPC) 34,
Hard contact 341 (golden finger) is provided on flexible PCB 34, flexible PCB 34 is stretched out by pedestal 31 and touched by metal
Point 341 is inconsistent with the metal clips 342 on mainboard 104.It is connected to mainboard by the flexible PCB 34 of touch sensing 32
Pedestal 31 is grounded by mainboard 104 on 104, certainly, pedestal 31 can not also be grounded in other embodiments, flexible electrical
Road plate 34 can also be realized by various electrical connectors between mainboard 104 it is detachable be fixedly connected, to maintain easily, profit
In replacement touch control component.
Opening 310 is equipped on substrate 311 and in the region of basic ring 312, the outer ledge of substrate 311 corresponds to opening
310 are equipped with notch 310a, and one end of touch sensing 32 is connected with flexible PCB 34, flexible PCB 34 by opening 310 and
Notch 310a stretches out in pedestal 31.By the 310 and notch 310a that is open, flexible PCB 34 can be conveniently set up, makes it will
Touch sensing 32 is electrically connected with mainboard 104.It can be generated to avoid between flexible PCB 34 and support element 2 using notch 310a
Interference.Certain deformation can occur in the moving process that touch control component 3 is pressed and bounced and be electrically connected without influencing for flexible PCB 34
Link, it is easy to use, prolong the service life.It herein, in other embodiments, can also be by being arranged on basic ring 312
Opening, to facilitate setting flexible PCB 34.
Pressing of the switch 1 for user inputs, and when user's pressing keys device 200, touch control component 3 is in user's pressing force
It is moved to close to 1 direction of switch under effect, switch 1 is triggered.Mechanical press-key apparatus switching function can be realized to keep away by switch 1
Exempt from accidentally to touch.
Preferably, switch 1 can be fixed on mainboard 104, to make switch be connected to other electronic components of mainboard 104
On, to realize the control function of switch.Preferably, switch 1 can be an integral structure with mainboard 104, to make switch connect
To other electronic components of mainboard 104, to realize the control function of switch, while mainboard 104 and key device can be improved
200 integrated level is convenient for terminal miniaturization, and conducive to assembly.Herein, in other embodiments, switch 1 can also be arranged
On the first interior structural support part 103 or other component in terminal.
Switch 1 be preferably film key device, in other embodiments, switch can also be patch type touch-switch or
Other mechanical switch key devices such as conductive rubber switch.Utilize switch and touch control component 3 so that key device is provided simultaneously with
Mechanical key and touch function, the touch of user and push can provide two different electric signals, realize in a portion
Various control function is realized on part.When user's pressing keys device, touch sensible signal and switch 1 can be triggered simultaneously, from
And realize and realize various control function on one component, save structure space.Two of touch sensing 32 and switch 1 generation
Control signal may be respectively used for control different function, can also control identical function simultaneously, such as control signal when two
Just start a certain function when generating simultaneously, so as to effectively avoid accidentally touching.
Support element 2 is silica gel seat so that it is supported on the lower section of touch control component 3 with certain deformation nature, when touch-control group
When part 3 is moved to switch 1, support element 2 can deform upon, and touch control component 3 is enable to move down, and simultaneously support part 2 and may be used also

As shown in Fig. 3 and Fig. 7, the medium position of support element 2 is provided with through-hole 20, and the lower surface of pedestal 31 is equipped with convex block
314;Convex block 314 passes through through-hole 20 and contradicts onto switch.When support element 2 touch control component 3 by pressure in deformed state when,
Convex block 314 is resisted against switch 1, with trigger switch 1.Since convex block 314 is extended to form by pedestal 31, convex block 314 is pedestal 31
A part is also made of metal, convenient to apply pressure against switch 1 and to switch 1 with certain degree of hardness.In the present embodiment,
Switch 1 be film key device, metal dome switch 1 can be made to be triggered when being depressed by convex block 314 and provide the user with by
Pressure feedback, to generate switching signal.It, can phase mutual connection between convex block 314 and switch 1 when touch control component 3 is not pressed
It touches, since switch is thin film switch, the restoring force of 3 upward sliding of touch control component can be provided using its metal dome.
In present embodiment, as shown in figure 3, support element 2 is fixed on mainboard 104, and the first interior structural support part 103
By 2 pressing of support element on mainboard 104, touch control component 3 is fixed on support element 2, and switch 1 is fixed on mainboard 104 corresponding
At the bump position of 31 bottom of pedestal, when pressing touch control component 3, convex block touch switch so that switch is triggered, to real
The pressing at current family inputs.Touch control component 3 is supported on to the top of switch 1 using support element 2, in favor of trigger switch 1.Touch-control
The pedestal 31 of component 3 can be fixed on support element 2 by glue so that touch control component 3 and support element 2 connect into one it is whole
Body positions touch control component 3 by mounting hole 110, while the first interior structural support part 103 presses support element 2, can be with
So that fixed connection structure need not be used between support element 2 and mainboard 104, directly so that support element 2 is resisted against mainboard 104 i.e.
Can, to connection convenient for assembly.
The above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also considered as
Protection scope of the present invention.
