Description

A kind of key structure of touch panel

Technical field

The utility model relates to a kind of press-key structure, relates in particular to a kind of press-key structure that has touch pad, goes in the hand-held digital equipment such as mobile phone.

Background technology

The input keyboard of mobile phone generally comprises two kinds at present, a kind of is the mechanical type keyboard, as shown in Figure 1, this keyboard mainly must be out of shape by metal clips makes the key circuit contact realize the conducting or the disconnection of circuit, a kind of two-part feel is in use arranged, can not realize hand-written and touch importing but shortcoming is the keyboard face.Another is the touch pad keyboard, as shown in Figure 2, it mainly realizes that with PCB circuit is connected by connector by the capacitance/resistance tactile sensor, use pen or finger touch transducer, detect this position by circuit, realize the function input with special-purpose software, but shortcoming is the two-part feel that lacks button pressed.

In addition, day, are called in " stand hand-set of band keyboard and touch-screen " in Chinese utility model patent notification number CN2565217Y, Augusts 6 in 2003 day for announcing, a kind of mobile phone with keyboard and touch-screen is disclosed, it has general mechanical type keyboard simultaneously and has touch-screen simultaneously concurrently, but its shortcoming is, keyboard and touch-screen separately, and display screen and touch-screen adopt same screen, when adopting touch-screen, effective indication range of display screen is just very little.

The utility model content

Technical problem to be solved in the utility model has provided a kind of key structure of touch panel, and it not only can be realized hand-written and touch input, and have the button feel when touching input.

In order to solve above technical problem, the utility model provides a kind of key structure of touch panel, it comprises the touch pad input keyboard, below described touch pad input keyboard, comprise a mechanical type press-key structure, described mechanical type press-key structure comprises metal clips layer and key circuit, be equipped with corresponding metal clips on described metal clips layer and with the corresponding position of the button of described touch pad, described metal clips is corresponding with described key circuit.

Described mechanical type press-key structure also comprises key support, described key support be positioned at described metal clips layer above, its with the corresponding position of the button of described touch pad input keyboard on have groove, be provided with the contact with the corresponding position of the metal clips of described metal clips layer.

Because adopt the utility model below the touch pad input keyboard, to increase a mechanical type press-key structure, so not only can realize hand-written and touch importing, and when touching input, if button can pass through this mechanical type press-key structure, not only realized input downwards, also have feel simultaneously, increased key support in addition, it can be absorbed in the less pressure when realizing touch function, avoids producing simultaneously the faulty operation of signal.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.

Fig. 1 is the existing mobile phone schematic diagram that has the mechanical type input keyboard;

Fig. 2 is the existing mobile phone schematic diagram that has touch pad;

Fig. 3 is the utility model input keyboard structure exploded perspective view;

Fig. 4 is the utility model input keyboard section of structure;

Fig. 5 is a touch pad structure exploded perspective view of the present utility model;

Fig. 6 is a key support structure exploded perspective view of the present utility model.

Embodiment

As shown in Figure 3, it is the utility model input keyboard structure exploded perspective view.It comprises touch pad 1, touch inductor 2, key support 3, metal clips layer 4, wiring board (PCB) 5 from top to bottom successively.Wherein, dull and stereotyped button 1 and touch inductor 2 have been formed the touch pad input keyboard, and key support 3, metal clips layer 4 and wiring board 5 have been formed the mechanical type press-key structure.

As shown in Figure 4, it is the utility model input keyboard section of structure.At first, the user uses pen or during finger touch touch pad 1, to this position, and uses professional software to realize the function input by 2 circuit inductance on the touch inductor.Secondly, can also press down touch pad 1,, especially make metal clips 6 distortion of metal clips layer 4 by the contact 10 of key support 3 reverse side by the strain of key support 3, make with corresponding wiring board on 5 circuit connect and realize that circuit turn-on, this moment have the two-part feel.

As shown in Figure 5, it is the touch pad structure exploded perspective view of the utility model mobile phone.Described touch pad 1 is divided into two-layer up and down; the upper strata adopts the PET material to make; the spacing film of lower floor for making by the TPU material; have groove 7 on the upper strata; make button form elastic arm; can make button have deformability like this; the problem that button partly sink after can avoiding so repeatedly using; and spacing film can increase the deformability of PET, has stopper slot 8 simultaneously on spacing film, and it can prevent the slip of about the upper strata or front and back; spacing film also can absorb less pressure; avoid following mechanical type button is produced rub-out signal, it also has waterproof in addition; dustproof; electrostatic-proof function can also play the effect of protection touch inductor certainly.

As shown in Figure 6, it is the utility model key support structure exploded perspective view.Key support 3 has tow sides, has groove 9 in the front, forms elastic arm, makes its more easy deformation, after the distortion, presses down the metal clips 6 of metal clips layer by the contact 10 of reverse side, is connected the realization circuit turn-on with circuit on the wiring board; Certainly because the existence of key support is arranged, absorb the less pressure when realizing touch function, avoided producing simultaneously the faulty operation of signal.

In conjunction with Fig. 4-6 as can be known, the pass of the groove 9 on the groove 7 on the dull and stereotyped button 1 and the key support is corresponding design, and the size and the shape of groove 7 and groove 9 can be set as required, and contact 10 and metal clips 6 also are to adopt corresponding design.

Claims
