In order to be applied to the mobile phone of various moulding, the key groups of various different shapings is just constantly weeded out the old and bring forth the new.Yet, the key groups excessive height of prior mobile phone, the development trend light, thin, short, little with mobile phone is not inconsistent, the key groups structure of prior art is: a circuit board, the number of metal key is arranged on the circuit board, be an electro-insulating rubber layer on it, it contacts with metallic bond and is ad hoc little fore-set, and this fore-set makes things convenient for button; More have, the special plastic key that is provided with of metallic bond is placed on the above-mentioned rubber layer relatively.The key mode of said structure is: during button, press plastic key, it will be pressed into the electro-insulating rubber layer, and the little fore-set of this rubber layer is depressed metallic bond, produces signal on circuit board, and button is finished.
The shortcoming of above-mentioned press-key structure is that the little fore-set of above-mentioned metallic bond and rubber layer need occupy than large space, makes keypad blocked up, and the development trend light, thin, short, little with mobile phone is not inconsistent.
Summary of the invention
For addressing the above problem, the utility model proposes a kind of hand-hold electronic equipments of touch-controlled key, reduce hand-hold electronic equipments thickness.
One of the utility model purpose is, a kind of hand-hold electronic equipments of touch-controlled key is provided, this hand-hold electronic equipments comprises a housing, enclosure interior forms a space, be provided with a circuit board in the space, this circuit board group is located on the shell bottom wall, and this circuit board top is provided with a touch panel, this touch panel and the electric connection of this circuit board; One printed layers is arranged at the corresponding surface of this touch panel and this circuit board opposite face, and is printed with corresponding key position; Wherein, special design has an impedance circuit on the above-mentioned Trackpad, and the control chip of a processing signals, and this circuit and chip all have electric connection with this Trackpad.The user can import by contact panel whereby, and the press-key structure in the prior art need be set, and so can make this hand-hold electronic equipments more frivolous.
One of the utility model purpose, for a kind of hand-hold electronic equipments of touch-controlled key is provided, it sets up thinfilm protective coating on printed layers, with protection touch panel and printed layers.
One of the utility model purpose, for a kind of hand-hold electronic equipments of touch-controlled key is provided, the sidewall of its housing is provided with supporting bracket above circuit board, and this supporting bracket is to extend towards the space relative direction, and this supporting bracket is parallel with circuit board, with the convenient touch panel that supports.
One of the utility model purpose for a kind of hand-hold electronic equipments of touch-controlled key is provided, forms one at interval between its touch panel and the circuit board.
Compared to prior art, the utility model utilizes a touch panel and is printed in its surperficial key position and forms a touch-controlled key plate, so directly utilize the key groups in this touch-controlled key plate replacement prior art, thereby be beneficial to the thickness that reduces hand-hold electronic equipments, make hand-hold electronic equipments more frivolous and increase attraction.Can pass through to adjust the distance between circuit board and the touch-controlled key plate simultaneously, thereby make the space on the circuit board utilize fully, thereby be beneficial to arranging of circuit board, reduce its manufacture difficulty thereby be beneficial to.
Description of drawings
Fig. 1 the utility model product structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing in detail an embodiment of the present utility model is described in detail.
Present embodiment will illustrate design of the present utility model with the structure of mobile phone.
As shown in Figure 1, the utility model is a kind of hand-hold electronic equipments of touch-controlled key, this hand-hold electronic equipments comprises a housing 10, the housing 10 inner spaces that form, be provided with a circuit board 20 in the space, the main electronic building brick of this action phone all is mounted on this circuit board as processor, radio-frequency module etc., this circuit board 20 is mounted on the shell bottom wall, as directly being locked together on the diapire of housing 10 by screw etc.
And these circuit board 20 tops are provided with a touch panel 30, this touch panel 30 electrically connects with this circuit board 20, be the convenient touch panel 30 that supports, the sidewall of above-mentioned housing 10 extends relatively in the above-mentioned space above circuit board 20 and is provided with supporting bracket 110, and this supporting bracket 110 is parallel with circuit board 20.
This touch panel 30 is provided with a printed layers 40 with the corresponding surface of these circuit board 20 opposite faces, is printed with corresponding key position on these printed layers 40 surfaces; And set up thinfilm protective coating 50 on this printed layers 40, with protection touch panel 30 and printed layers 40.
In addition, special design has an impedance circuit on this above-mentioned touch panel 30, and the control chip 60 of a processing signals, and this circuit and control chip 60 all have electric connection with this touch panel 30.The impedance circuit of present embodiment can use the technology such as Quantum Corporation (Quantum), shifts induction pipe with two electric charges, works on the easy linear resistance assembly; The control chip 60 of processing signals uses the QSlideTM chip of Quantum Corporation (Quantum).The user can import by touch panel 30 whereby, and the press-key structure in the prior art need be set, and so can make this hand-hold electronic equipments more frivolous.
This kind mode is compared with prior art, the utility model utilizes touch panel 30 and the printed layers 40 of being located at touch panel 30 1 surfaces to form the touch-controlled key plate, so do not need the key groups of prior art included press structure such as keyframe, can effectively reduce the height of button on the one hand, thereby make electronic equipments such as this mobile phone more frivolous, also can reduce the component count of electronic equipments such as this mobile phone on the other hand, thereby be more conducive to make and reduce product cost; Simultaneously, since reduced the key groups of prior art included press structure such as keyframe, make and form a spacing distance between this touch panel 30 and the circuit board 20, circuit board surface like this also is regardless of to be limited to and is arranged the electronic building brick of establishing as prior art than low height, the electronic building brick that is the big height of tool also can be assembled on this circuit board 20, therefore the space of selecting in the design of circuit board is bigger, thereby reduces the difficulty that circuit board is made.
