The utility model discloses a smooth book support frame of embodiment is different completely with current cylindric support frame structure, the smooth book support frame of the embodiment of this disclosure has adopted the constitution of semicircle post and two arc splices to have become a new support frame structure, vice body and protection architecture parcel out a hollow structure, this hollow structure has protected the binding district that the vice body front portion was pasted, and can place flexible printed circuit board in this hollow structure, flexible printed circuit board has also been protected, after having set up the flexible display screen, the support end supports on the vice body that has the flexible screen, the stability of smooth book support frame has further been guaranteed, user experience has been promoted. The schematic structure of the roll support frame after being adhered to the flexible display 6 can be shown in fig. 2.
The structure of smooth book support frame that this disclosed embodiment provided not only can make bonding district and flexible printed circuit board can receive and release inside the pivot, has also protected the region near bonding district, and stress is dispersed, has solved the flexible display screen part damage or the demonstration inefficacy phenomenon that stress concentration leads to, has promoted the life of flexible display screen, has improved user experience.
The circle center 5 may be a hollow ring for supporting the rotation of the roll support frame in a manner of a central shaft, or may be a hollowed structure without a supporting manner of the central shaft.
During specific implementation, in order to ensure that the sliding roll supporting frame has a better effect, the radius of the circumference where the auxiliary body is located is smaller than that of the circumference where the protection shell is located, so that the protection shell is located outside the auxiliary body and wraps a flexible display screen to be arranged on the auxiliary body.
In order to make the roll support frame have a more rounded structure, the radius of the circle where the main body is located is preferably equal to the radius of the circle where the secondary body is located, but of course, the radius of the circle where the main body is located may also be larger than the radius of the circle where the secondary body is located.
As for the total length of the protective casing, if it is set shorter, for example, less than a predetermined length, the bezel area can be further reduced, and the area of the display region can be increased.
One end of the auxiliary body is detachably connected with one end of the semi-circumference of the main body, and/or one end of the protective shell is detachably connected with the other end of the semi-circumference of the main body; through the arrangement, the auxiliary body can be detached when the flexible display screen is lapped, the bonding area of the auxiliary body is connected with the bonding area of the flexible display screen, and the flexible printed circuit board 8 below the bonding area can be placed in the space between the rotating shafts. As shown in fig. 2 and 3, the bonding state is achieved in two cases, in fig. 2, the flexible printed circuit board is in a housed state, and in fig. 3, the flexible printed circuit board is in a state of being connected to the system board interface 9.
As shown in fig. 4, to further reduce the stress caused by the rolling of the flexible display, the supporting end 4 extends to the outer surface of the sub-body 2 with a predetermined inclination angle, as shown in fig. 5, so that the flexible display can be smoothly supported when being rolled. Of course, in order to reduce the surface area of the supporting end 4 and further reduce the area of the frame, the material used for the supporting end may be at least low modulus elastic material or foam material, so as to further reduce the stress concentration phenomenon caused by the break of the supporting end from the material aspect, and reduce the stress, and further the stress can be reduced when the supporting end without the inclined angle shown in fig. 1 is used, that is, the adjustment structure is changed by the improvement of the material.
The protective shell can use shape memory alloy, such as Au-Cd, ag-Cd, cu-Zn-Al, cu-Zn-Sn, cu-Zn-Si, cu-Sn, cu-Zn-Ga, in-Ti, au-Cu-Zn, niAl, fe-Pt, ti-Ni-Pd, ti-Nb, U-Nb and Fe-Mn-Si alloy systems, and the content of various metal elements can be defined according to actual requirements. The alloy can change the self lattice orientation under the condition of stress so as to reduce the elastic modulus, and can reduce the stress on the screen above the protective shell when being curled.
