The hot melt post is positioned on the periphery of panel lower surface;
The keyboard fixed leg is positioned on the periphery of handset front case;
Described panel is fixed on the handset front case by described hot melt post;
Wherein, the user pushes described control button, causes panel to produce deformation, touches the PCB circuit board and sends control command.
Described mobile phone press-key construction also comprises: rubber layer is positioned under the described panel.
The center of described control button is 4.9mm to the distance at edge.
The thickness of described rubber layer is 0.6mm＜C＜1.2mm.
The computing formula of the space of described panel is D＞0.3I/A, and the I value is an outward appearance button length numerical value, and A is the distance of the center of control button to the edge.
The space of described panel is 0.7mm.
The thickness of described panel is 0.6-0.7mm.
The gap of described control button and peripheral structure spare is 0.3mm.
The height of described hot melt post is 0.8mm.
The diameter of described hot melt post is 0.7mm.
The beneficial effects of the utility model are:
Adopt mobile phone press-key construction of the present utility model, improve the internal structure layout, strengthen and press bond strength, make the key sense of user when button good.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, a kind of mobile phone press-key construction of the present utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Mobile phone press-key construction of the present utility model is realized the mobile phone press-key construction that the key sense is good, intensity is big by changing the factors such as gap at button area, plate thickness and button and edge.
Fig. 1 is the exploded view of mobile phone press-key construction of the present invention, Fig. 2 is the front view of handset front case among the present invention, as depicted in figs. 1 and 2, described mobile phone press-key construction, comprise: panel 1, a plurality of control button 2, fixedly band 3, hot melt post 4, keyboard fixed leg 5, handset front case 6, keyboard 7 and PCB circuit board 8, wherein:
A plurality of control buttons 2 are corresponding with described control area 11 respectively; Described control area is positioned on the keyboard 7, overlaps with the control button of keyboard 7;
Control button in the utility model does not comprise the digital button on the numeric keypad.
Fixedly band 3, are positioned on the control button 2, and described control button 2 relies on described fixedly band 3 to be bonded on the described control area 11;
Hot melt post 4, be positioned at panel 1 lower surface periphery on;
Keyboard fixed leg 5 is positioned on the periphery of handset front case 6;
Described panel 1 is fixed on the handset front case 6 by described hot melt post 4;
Wherein, the user pushes described control button 2, causes panel 1 to produce deformation, touches corresponding keyboard 7, and then touches PCB circuit board 8 to send control command.
Fig. 3 is the overall schematic of mobile phone press-key construction of the present invention, Fig. 4 is the profile of mobile phone press-key construction of the present invention along the A-A line, Fig. 5 is the profile of mobile phone press-key construction of the present invention along the B-B line, as Fig. 3, Fig. 4 and shown in Figure 5, described keyboard 7, comprise: rubber layer 9 is positioned at below the described keyboard 7.
Preferably, because the center of control button is far away more to the distance at edge, panel (Deco_Front) is easy deformation more, and key is sympathetic good more, as a kind of embodiment, and design A=4.9mm.
Preferably, because the altitude measurement of rubber layer (Rubber) is more little, key sense numerical value is big more, but too little key sense hardens, standard 0.6mm＜thickness C＜1.2mm, and as a kind of embodiment, design C=1.0mm.
The space of panel (Deco_Front), computing formula D＞0.3I/A, the I value is an outward appearance button length numerical value, the A value is the distance of the center of control button to the edge, as a kind of embodiment, design D=0.7mm.
Preferably, because the little easy deformation of thickness of panel (Deco_Front), can fracture, therefore, recommend H:0.6-0.7mm but hour do fall-down test very much.
Fig. 6 is the detail view of mobile phone press-key construction of the present invention, and is without hindrance at the volley for guaranteeing control button (Deco_Keypad) as shown in Figure 6, considers manufacturing tolerance and organizes tolerance, carries out gap design:
1.=0.3mm; 2.=0.3mm; 3.=0.3mm (gap of Deco_Keypad and peripheral structure spare)
The beneficial effects of the utility model are:
Adopt mobile phone press-key construction of the present utility model, improve the internal structure layout, strengthen and press bond strength, make the key sense of user when button good.
