To further illustrate the technical scheme of the present invention below with reference to the accompanying drawings and specific embodiments.
Referring to FIG. 1 to FIG. 7, the present embodiment provides a kind of electronics, including fold mechanism, 9 and of flexible display screenTwo liquid crystal displays 8.
Referring to FIG. 1 to FIG. 3, fold mechanism includes that center shrimp shell chain link 1, two is symmetrically set about the center shrimp shell chain link 1The first side shrimp shell chain link 2 for setting, universal coupling 4, two are about the symmetrically arranged second side shrimp shell of the center shrimp shell chain link 1Chain link 3, two is about the symmetrically arranged shell mould group 5 of the center shrimp shell chain link 1 and two slide hinges 6.Preferably, each describedThe inside of shell mould group 5 is fixedly connected with a liquid crystal display 8；Flexible display screen 9, the flexible display screen 9 and twoThe outside of the shell mould group 5 is fixedly connected.
The first side shrimp shell chain link 2 is equipped with the first crescent 201.The universal coupling 4 is installed on the center shrimpConnected on shell chain link 1 and respectively with the two first side shrimp shell chain links 2 so that the two first side shrimp shell chain links 2 withThe center shrimp shell chain link 1 is rotatablely connected.The first side shrimp shell chain link 2 is between two second side shrimp shell chain links 3；InstituteIt states the second side shrimp shell chain link 3 and is equipped with the first crescent moon boss 301 close to the side of the first side shrimp shell chain link 2；DescribedOne crescent moon boss 301 is inserted into first crescent 201.The second side shrimp shell chain link 3 is located at the two shell mould groups 5Between, the shell mould group 5 is equipped with oblique chute 501 close to one end of center shrimp shell chain link 1.One end of the slide hinge 6 withOne oblique chute 501 is slidably connected, and the other end and the center shrimp shell chain link 1 are rotatablely connected；When the slide hinge 6 and instituteWhen stating oblique chute 501 and being slidably connected, the first crescent moon boss 301 is synchronous to be slidably connected with first crescent 201 with realityThe existing fold mechanism unfolds and folds operation.
Specifically, referring to fig. 4, when fold mechanism is in unfolded state, five shrimp shell chain links are in one line, Flexible DisplaysThe available effective support in intermediate position of screen 9.Referring to Fig. 5, when being folded, by the shell mould group 5 at both ends intoRow infolding, slide hinge 6 can be slided along oblique chute 501, be synchronized to the first side shrimp shell chain link 2 and the second side shrimp shell chain link 3It is squeezed；First side shrimp shell chain link 2 due to by active force under the action of universal coupling 4 around center shrimp shell chain link 1 intoRow rotation inwards, while the second side shrimp shell chain link 3 is slided by active force along the first crescent 201 inwards with first bySide shrimp shell chain link 2 is rotated inwards, and final five shrimp shell chain links are accommodated the shape of similar sector.Each shrimp shell chain link aroundRespective rotation center is rotated, and the outside overall length of five shrimp shell chain links is constant after being unfolded and being closed, i.e. five shrimp shell chain linksConstant with the overall length of 9 bonding position of flexible display screen, this can greatly reduce institute during folding and unfolding of flexible display screen 9The tension and pressure received.Therefore, fold mechanism provided in this embodiment can play stable supporting role to flexible display screen 9,The stress of damage flexible display screen 9 will not be applied to flexible display screen 9 again.
Preferably, referring to Fig. 6~Fig. 7, universal coupling 4 can use existing universal coupling 4, can also use this implementationThe universal coupling 4 that example provides.The universal coupling 4 includes two rotation sections, and the rotation section includes L-type plate 401, L-type axis 402, ZType fixed part 403 and rotating shaft 404.One end of the L-type plate 401 is equipped with vertical holes, and the other end is equipped with lateral aperture；The LOne end of profile shaft 402 and the lateral aperture are rotatablely connected；One end of the Z-type fixed part 403 is another with the L-type axis 402End rotation connection, the other end of the Z-type fixed part 403 are fixedly connected with the first side shrimp shell chain link 2；Two rotationsThe vertical holes in portion is rotatablely connected with the rotating shaft 404.Further, one of L-type plate 401 is outward extended with fixationHole 4011, the universal coupling 4 are rotatablely connected by the fixation hole 4011 with the center shrimp shell chain link 1.Specifically, L-typeThe setting of axis 402 is so that Z-type fixed part 403 can be with multiple-directional rotating, to be conducive to the first side shrimp shell chain link 2 and center shrimp shellThe Positive rotational of chain link 1 connects.
In the present embodiment, positive stop lug boss is extended to side in described first crescent moon boss, 301 one end far from its root302；The side of first crescent 201 is hatch frame, and the top of the other side is equipped with for stopping the positive stop lug boss 302Postive stop baffle 202.Specifically, when positive stop lug boss 302 slides into postive stop baffle 202, five shrimp shell chain links just word rowIt opens, avoids bending that flexible display screen 9 is excessively caused to damage.
Fold mechanism further includes turning joint 7, one end of the turning joint 7 with described 2 turns of first side shrimp shell chain linkDynamic connection, the other end and the second side shrimp shell chain link 3 are rotatablely connected.Specifically, turning joint 7 is conducive to the first side shrimpShell chain link 2 is connected with the Positive rotational of the second side shrimp shell chain link 3.Further, in order to realize reliable rotation connection, this realityIt applies in example, the second side shrimp shell chain link 3 is equipped with the second crescent moon boss 303, the shell close to the side of the shell mould group 5Body mould group 5 is equipped with the second crescent 502 close to the side of the second side shrimp shell chain link 3, and the second crescent moon boss 303 is insertedEnter in second crescent 502.Preferably, the first crescent moon boss 301 and the second crescent moon boss 303 tilt upward and prolongIt stretches.The end of the center shrimp shell chain link 1 is equipped with third crescent moon boss 101, and the end of the first side shrimp shell chain link 2 is equipped withThird crescent 203, the third crescent moon boss 101 be inserted into the third crescent 203 and with the third crescent 203It is slidably connected.Specifically, when slide hinge 6 and oblique chute 501 are slided, synchronization is slided between each crescent moon boss and crescentIt is dynamic, it is ensured that stable rotation relation and rotation path are kept between each shrimp shell chain link.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodimentsInvention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementationTechnical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification orReplacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
