Description
Technical field
The utility model relates to a kind of chain hinge, specially a kind of chain hinge of flexible screen belongs to chain hinge
Technical field.
Background technique
Screen is in electronic equipment for showing the device of image and color.With the continuous development of science and technology, flexible
Screen is gradually current electronic equipments.It is growing for electronic equipment small size, large screen in order to meet people
Requirement, by flexible screen be used for collapsible display become current research staff research and development focus.
The application utility model people has found that collapsible display is soft at folding when opening in R&D process
Property screen is often difficult to sufficiently flatten, while in a folded configuration, inevitably can be to being in if flexible screen also further folds
Flexible screen at folding causes a degree of damage, to further influence the display quality of collapsible display, it is difficult to
Meet the use demand of user.
Continuous universal with what is shielded comprehensively, mobile terminal is while pursuing large-size screen monitors visual experience, also balanced better
Portability, the physics limit of single screen are the screen accounting that 100% is realized in the case where that can hold size.In portable premise
Under, in order to pursue bigger screen, folding mobile is developed, current folding mobile is realized using double screen, exhibition
Have between two pieces of screens after opening and significantly isolate sense, cannot achieve the perfection of visual effect.
Flexible screen technology is quickly grown, and in addition to flexible flexible screen, folding flexible screen also occurs, foldable soft
Property screen is due to there was only one piece of screen, and whole visual effect is more perfect after expansion.Flexible screen Foldable mobile terminal is according to folding
Position where poststack screen can be divided into interior bending flexible screen mobile terminal and outer bending flexible screen mobile terminal, wherein occurring curved
Bent screen area is known as deformable screen area.For interior bending mobile terminal, after folding screen in the inside of mobile terminal,
It is protected by the shell of mobile terminal, has better shock resistance.Though but bending mobile terminal can be real in the prior art
Existing jackknife action cannot achieve under folded state due to the non-stretchable characteristic of screen entirety to the receipts of deformable screen area
Hold the support function under function and unfolded state to deformable screen area.
Chinese Patent Application No. 201810078223.8 discloses a kind of Foldable mobile terminal, including flexible screen, flexibility
Transparent cover plate and shell are provided with the first glue all over the screen between one side surface of the flexible screen and the flexible and transparent cover board
Layer, folding edges at two ends of the flexible screen away from a side surface of the flexible and transparent cover board are corresponding with the shell
Edges at two ends be respectively arranged with the second local glue-line.The Foldable mobile terminal of the utility model is steady in folding process
Fixed to fix and damage to screen itself, structure is reliable, and stability is good, injures to screen small；And flexible screen and
Shell is locally bonded, so that flexible screen and shell have the fold domain of contact to have relative displacement, it is curved can to effectively reduce flexible screen
Tensile stress of the shell to screen when folding.
But these fold mechanisms are there is during opening and closing, and having for lateral surface and medial surface is certain
Gap；Or the distance of lateral surface and medial surface changes, and is not able to maintain inside and outside synchronous problem.
Utility model content
The purpose of this utility model is to provide for a kind of chain hinge of flexible screen, to solve the above-mentioned of the prior art
Technical problem.
The purpose of this utility model is achieved through the following technical solutions.
A kind of chain hinge of flexible screen, including there are two axis holes for two and half gears, two hinge pins and two bands
Fixed plate；The fixed plate is placed in the both ends of half gear, and two and half gears pass through axis in two hinge pins and fixed plate
Hole is coupled and is intermeshed；Half gear is extended with a linking arm along a tangential direction, and the end of linking arm is provided with
Sliding pin；Balladeur train is installed, balladeur train is U-shaped structure, and inner wall is provided with to match with sliding pin on the elastic sheet
Sliding slot；The chain hinge and the bindiny mechanism of flexible screen, the supporting mechanism of flexible screen or flexible screen are fixed.Due to
In half gear rotation process, relative displacement occurs between balladeur train and sliding pin, therefore, passes through movement of the sliding pin in sliding slot
To eliminate the influence of relative displacement.
Further, at least one is fixed between plate end face and hinge pin and is equipped with the friction pad coaxial with pin shaft
Piece.
The chain hinge is provided with two groups, is respectively arranged at flexible screen, the supporting mechanism of flexible screen or flexibility
Close to the position at both ends in the bindiny mechanism of screen.
The supporting mechanism of the flexible screen is the elastic sheet or installation frame that humidification is played under flexible screen；
The bindiny mechanism of the flexible screen is other known bindiny mechanism.
The utility model has the following beneficial effects: chain hinge guarantees that two frames are synchronous, simultaneously in closing course
In order to guarantee that outer lateral extent is constant, therefore hinge two sides sliding equipment will start to inside contract along sliding trace, uncompensation distance.
