Embodiment

Fig. 2 A represents this slide mechanism schematic diagram of one embodiment of the invention, and wherein slide mechanism is in opening.Fig. 3 A represents the slide mechanism schematic diagram of one embodiment of the invention, and wherein this slide mechanism is in closure state.See also Fig. 2 A, Fig. 3 A, aforementioned slide mechanism 500 is arranged in a slide electronic device, for example be movably connected as shown in Figure 1 input module 100 and display module 200 are used for avoiding input module 100 and display module 200 cause the distortion of flexible circuit board F buckling and damage at sliding process.For example, aforementioned electronic can be a mobile phone, personal digital assistant, palmtop computer (pocket PC), super removable computer (ultra mobile personal computer, UMPC) or plate computer (tablet PC) etc.What need to specify is, when slide mechanism is in opening, and input module 100 and display module 200 only overlap (similar Fig. 1); Yet when slide mechanism 500 was in closure state, input module 100 and display module 200 be state in an overlapping.

Slide mechanism 500 in the present embodiment mainly comprises one first member 10, a second component 20, a sliding part 30, a wires W, at least one elastic component S and a flexible circuit board F, wherein the first member 10 is fixed on

input module

100,20 of second components are fixed on display module 200, when input module 100 slided with respect to display module 200, the first member 10 can slide along Y direction with respect to second component 20.

What need special instruction is, separately be provided with a drive pulley P on second component 20, wherein the two ends of wires W connect respectively sliding part 30 and the first member 10, when the first relative second component 20 court-Y directions of member 10 are slided (as shown in Figure 3A), wires W can be subject to the first member 10 tractions and move around drive pulley P.in addition, by Fig. 2 B, can find out in Fig. 3 B, sliding part 30 is arranged at the first side 21 of second component 20 tops, the first 10 of members are arranged at the second side 22 of second component 20 belows, be formed with one first opening G between the body 31 of aforementioned sliding part 30 and the first body of rod R1, flexible circuit board F extends towards Y direction from the first side 21 of second component 20 tops, then sequentially pass one second opening H on aforementioned the first opening G and second component 20, and then arrive the second side 22 of second component 20 belows, be used for being electrically connected to aforementioned input module 100 and display module 200.Wherein, flexible circuit board F forms respectively first, second kink F1, F2 on the second body of rod R2 of the first body of rod R1 of sliding part 30 and second component 20, and makes flexible circuit board F have a S tee section.
