Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment
It is clearly and completely described.
The utility model embodiment provides a kind of fold mechanism and the terminal with the fold mechanism.The fold mechanism
Support the flexible screen of the terminal.The terminal can be tablet personal computer, mobile phone, flexible display, electronic reader, remote control
Device, personal computer (Personal Computer, PC), notebook computer, mobile unit, Web TV, wearable device
Deng.In the present embodiment, illustrated by taking tablet personal computer as an example.
Also referring to Fig. 1, the fold mechanism includes the first supporter 11, the second supporter 12 and kink 15.Institute
State kink 15 to be connected between the supporter 12 of the first supporter 11 and second, to realize that first supporter 11 is relative
The turnover of second supporter 12.The kink 15 includes locating rotation part 17 and is connected to first supporter 11 and second
Be hinged tumbler 16 between supporter 12.
The be hinged tumbler 16 includes multiple hinge bars 163, and the lateral surface of the multiple hinge bar 163 is collectively forming use
In the loading end 160 for carrying the flexible screen, the multiple hinge bar 163 is sequentially connected to the locating rotation part 17 side by side.
Such as Fig. 2, gap is provided between hinge bar 163 described in any two in the multiple hinge bar 163.The locating rotation part 17 is curved
Length is constant during folding, and the be hinged tumbler 16 is bent with the locating rotation part 17, and the gap reduces, and carries
The total length of face 160 is constant, so that the length after the loading end 160 bending is equal to the length when loading end 160 flattens.
The constant locating rotation part 17 of length drives the be hinged tumbler 16 curved when described fold mechanism passes through bending
Folding makes a hinge bar 163 mutually draw close, and bends loading end 160 and does not stretch, so that after the be hinged tumbler 16 bending
The length of loading end 160 is equal to the length of loading end 160 when the be hinged tumbler 16 flattens, and then makes to be fixed on the folding machine
The kink that bending region of the flexible screen of structure in bending is not folded over mechanism is stretched, i.e., will not be kept away by force-extension
Exempt to damage flexible screen.
