Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further described.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and without
It is of the invention in limiting.
Refering to Fig. 1, curvature governor motion of the invention is used for the curvature for adjusting curved-surface display device, curved-surface display device bag
Curvature governor motion 10 and flexible display screen 20 are included, curvature governor motion 10 mainly includes bottom plate 11 and is fixed on bottom plate 11
Traction component 12, preferably bottom plate 11 be display device support, the two ends of the width of display screen 20 are fixed on bottom plate 11
On, it can specifically set support feet 111 to clamp the two ends of display screen 20 respectively at the two ends of bottom plate 11.Traction component 12 is connected to
The middle part at the back of display screen 20, is pulled to the middle part of display screen 20, can caused towards the rear by traction component 12
The medial recess of display screen 20, so as to change the curvature of display screen 20.
As shown in figs. 2 to 4, traction component 12 specifically includes rotating shaft 121, cam 122 and translating element 123, cam 122 it is convex
Wheel face has a variety of apart from the distance of its center of rotation, preferred cam face by two ends arc surface and connection two ends arc surface it is oblique
Face so that cam 122 relative to its center of rotation during rotating, with the maximum radius of clean-up and minimum work half
Footpath.Cam 122 is fixed on one end of rotating shaft 121 by the axis hole of its center of rotation, and the other end of rotating shaft 121 is rotatably arranged in
On bottom plate 11, translating element 123 includes being used to be connected to the shaft-like connecting portion 1230 of the back intermediate region of flexible display screen 20
With the barrier rib 1231 perpendicular to connecting portion 1230, rotating shaft 121 is located between the free end of connecting portion 1230 and barrier rib 1231, and
The cam surface of cam 122 is connected to barrier rib 1231 towards the surface of connecting portion 1230.
Because the two ends of flexible display screen 20 are fixed on bottom plate 11, the middle part at the back of display screen 20 passes through connecting portion
1230 connection barrier ribs 1231, cam 122 is installed in rotation between barrier rib 1231 and display screen 20 by rotating shaft 121,
And it is connected to the inner surface of barrier rib 1231.As shown in Fig. 2 under original state, the minimum radius of clean-up of cam 122 is corresponding convex
Wheel face is connected to the inner surface of barrier rib 1231, or has certain interval with the inner surface of barrier rib 1231, and now, display screen 20 is in
Plane dispaly state；During cam 122 is rotated with rotating shaft 121, (the dorsad direction of display surface) is pushed away cam 122 towards the rear
Dynamic barrier rib 1231, connecting portion 1230 is the middle part for pulling display screen 20 so that display screen 20 is bent, with the reality of cam surface
The radius of clean-up becomes larger, i.e., the position and the distance of rotating shaft 121 that cam surface is abutted with barrier rib 1231 become larger, display screen
20 bending curvature is increasing, when cam 122, which turns to its maximum working radius, to be abutted with barrier rib 1231, display screen 20
With maximum bending curvature, user can need to be fixed on cam 122 into different angles, make convex according to different viewings
Barrier rib 1231 is abutted, so as to meet diversified usage scenario each site selective of the cam surface of wheel 122.In display
Screen 20 is from during plane switches to curved surface, and translating element 123 is promoted towards the rear, the reverse drawing of the display screen 20 suffered by it
Power gradually increases；In display screen 20 from during curved surface switches to plane, translating element 123 is made in the reversal interlocking relay of display screen 20
Under, pulled towards display surface direction, the reversal interlocking relay of the display screen 20 suffered by it is tapered into.
The translating element 123 of the present embodiment includes connecting portion 1230 and the cyclic structure being connected with connecting portion 1230, cam 122
It is contained in the cyclic structure, and cyclic structure is not less than cam 122 most in the width on the direction of connecting portion 1230
Twice of the big radius of clean-up, barrier rib 1231 is ring-type in cyclic structure in the part away from connecting portion 1230, such as Fig. 2~4
Structure is the framework of rectangle, and barrier rib 1231 is frame side of the framework away from connecting portion 1230, and the width of the framework must can not be small
In twice of maximum working radius of cam 122, it just can guarantee that cam 122 can be with normal rotation.In other embodiments, put down
The cyclic structure for moving part 123 can also be annular framework, and barrier rib 1231 is a part of arc of the framework away from connecting portion 1230
Shape block.
The type of drive of rotating shaft 121 can be designed freely, for example, driven gear can be arranged with rotating shaft 121, be driven
The drive gear of motor is rotated by the drive rotating shaft 121 of engaging with driven gear.Or, end and the driving horse of rotating shaft 121
The drive shaft coupling reached, is rotated by drive motor rotating shaft 121.
With reference to shown in Fig. 1 and Fig. 5, the curvature governor motion of the present embodiment also has supporting plate 13, and supporting plate 13 is located at aobvious
Between display screen 20 and rotating shaft 121, the one end of supporting plate 13 is fixed on bottom plate 11, and its other end offers through hole (figure is not marked),
Connecting portion 1230 stretches out after being passed through from the through hole, then the back fixed to display screen 20, the process rotated in cam 122
In, connecting portion 1230 correspondingly can reciprocatingly slide along through hole, the presence of supporting plate 13, can prevent from connecting during curvature is adjusted
There is crooked phenomenon in socket part 1230, and guiding connecting portion 1230 is only moved in fore-and-aft direction.
In addition, as shown in fig. 6, curvature governor motion can also have compression spring 14, by the way that compression spring 14 is arranged
In on connecting portion 1230, and its two ends is distinguished Elastic pusher translating element 123 and supporting plate 13, can prevent connecting portion 1230 from going out
It is existing stuck, make its slip in supporting plate 13 more smooth.The end of connecting portion 1230 can offer keyway, display screen 20
Back is convexly equipped with the mounting ring 21 of annular, and connecting portion 1230 is inserted in the groove that mounting ring 21 is surrounded, and recycles flat key T to pass through and turns
It is fastened in after axle mounting ring 21 in keyway, you can complete the installation of connecting portion 1230.
As shown in fig. 7, as another embodiment, curvature governor motion also has the installing plate 15 of strip, the peace
Dress plate 15 extends perpendicularly to bottom plate 11, and is fixed on the end of connecting portion 1230, for fitting in flexible display in the vertical
The back of screen so that the force of connecting portion 1230 can be equably applied on display screen 20, during curvature regulation, display
The deformation uniformity of screen 20 is more preferable.
It is understood that the structure of translating element 123 can also be as shown in figure 8, only need to pass through connection by barrier rib 1231
Portion 1230 is connected to the back of display screen 20, and cam 122 is connected to the inner surface of barrier rib 1231.
The curvature of the display screen of the curved-surface display device of the present invention can be adjusted by special curvature governor motion,
Under the rotation of rotating shaft, actuated by cams translating element drive flexible display screen medial recess, using cam surface different parts with
Being engaged for translating element can realize a variety of bending curvatures of flexible display screen, meet the viewing requirement of varying environment.
Described above is only the embodiment of the application, it is noted that for the ordinary skill people of the art
For member, on the premise of the application principle is not departed from, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as the protection domain of the application.
