Specifically, the electronic device 100 provided by the embodiment of the invention may be a mobile phone, a tablet, a game machine or other terminal electronic products with a folding screen. The first body 1 and the second body 2 may have the same structure, but the two bodies may have the same or different sizes, for example, the portions of the first body 1 and the second body 2 connected to the flexible display 3 may have the same or different sizes, but both the first body 1 and the second body 2 need to have a portion connected to the flexible display 3, and a first supporting portion 11 and a second supporting portion 12, and hereinafter, the first body 1 is mainly described in the embodiments of the present invention, and the second body 2 may be similar to the first body 1. The first body 1 and the second body 2 may be both flat plates, and one end of the first body 1 is rotatably connected to one end of the second body 2, and the specific rotational connection manner may be through a hinge, a rotating shaft, a flexible bendable connector (e.g., a flexible plastic body), and the like, and the specific rotational connection structure is not limited in the embodiment of the present invention. The rotation connection between first organism 1 and the second organism 2 can set up to 180 rotations, makes first organism 1 can rotate to the horizontally state of expansion from the state of lock with second organism 2, relative from 0 degree rotation to 180 degrees promptly to accord with the mode of buckling that current flexible display screen 3 can realize. Hardware for realizing the operation, control, and communication functions of the electronic apparatus 100 is provided in the first body 1 and the second body 2.
The flexible display screen 3 may be any type of display screen known to the skilled person, for example, the flexible display screen 3 may be formed by sequentially stacking a cover plate, a first optical adhesive layer, a touch layer, a display panel layer, a second optical adhesive layer, and an austenitic stainless steel plate layer.
The first side 33 of the flexible display 3 is the side facing away from the display light and the second side 34 is the side displaying the light. The fixed area 31 and the bending area 32 of the flexible display 3 are connected together, the division of the two areas is defined according to the work capacity of each part of the flexible display 3 when the electronic device 100 is bent, the fixed area 31 is respectively located at two sides of the bending area 32, the boundary between the fixed area 31 and the bending area 32 can be a straight line, during the specific work, the fixed area 31 is respectively fixed with the first body 1 and the second body 2 and rotates along with the fixed area, and in order to ensure that the bending area 32 can be bent along with the first body 1 when the first body 1 is rotatably fastened or horizontally unfolded relative to the second body 2, the bending area 32 should correspond to the position where the first body 1 and the second body 2 are rotatably connected, specifically, the central line of the bending area 32 when bent (i.e. the bending area 32 is a symmetrical bend) is parallel to the rotation axes of the first body 1 and the second body 2 (i.e. the axes of any rotating connection structure), and the midline is parallel to the plane of the axis and the first side surface 33 corresponding to the fixed area 31, i.e. the plane formed by the midline and the axis is parallel to the flexible display screen 3 when horizontally unfolded, so that the bending area 32 can be ensured to synchronously rotate with the first body 1 and the second body 2. In the process of relatively rotating and buckling the first body 1 and the second body 2, the bending region 32 bends under the propping action of the first supporting portion 11 and the second supporting portion 12, and the section of the bending region 32, which is perpendicular to the first side surface 33 and the rotation axis at the same time, is in a drop shape as shown in fig. 1.
The bending area 32 is bent to form a water drop-shaped section, so the bending area comprises an inward bending area 321 and an outward bending area 322, the inward bending area 321 corresponds to the head of a water drop bent to approximate an arc, the outward bending area 322 is the part of the inward bending area 321 in transition connection with the fixed area 31 and corresponds to the tail of the water drop, the bending directions of the outward bending area 322 and the inward bending area 321 are opposite, and the inward bending area 321 and the outward bending area 322 are both cambered surfaces. By making a tangent plane at the edge of the inward-bending region 321 and making a tangent plane at the edge of the outward-bending region 322, the intersection of the two tangent planes is the boundary between the inward-bending region 321 and the outward-bending region 322, and the boundary is a straight line, i.e., the boundary line 323. Since the inward bending area 321 corresponds to the head of the water drop, that is, the inward bending area 321 is bent to be approximately circular, as shown in fig. 1, the inward bending area 321 has a position with the largest diameter in the direction perpendicular to the first side surface 33 in the cross section, that is, the position with the largest diameter Φ of the water drop, when the first body 1 and the second body 2 are fastened to sandwich the bent flexible display screen 3, the position with the largest diameter Φ of the water drop corresponding to the inward bending area 321 is in contact with the first body 1 and the second body 2, and the contact position is a straight line, so the straight line is called a contact line 324. Supporting the second support portion 12 in the region where the line of contact 324 to the boundary 323 is part of the in-turned area 321 reduces the outward tension in this part of the in-turned area 321 and thus provides a smooth transition to the out-turned area 322. And as can be known from simulation after bending and stressing of the water drops of the flexible display screen 3, the second supporting portion 12 is arranged at the position from the contact line 324 to the boundary line 323, so that the stretching of the optical adhesive layer of the flexible display screen in the thickness direction during bending can be effectively reduced, and the cracking problem of the optical adhesive is further effectively solved.
In the technical solution of the present invention, the first body 1 and the second body 2 of the electronic device 100 are respectively and fixedly connected to the fixing area 31 of the flexible display screen 3, and the first body 1 and the second body 2 are both provided with the first supporting portion 11 and the second supporting portion 12, so that when the first body 1 and the second body 2 are relatively rotated and fastened, the fixing area 31 of the flexible display screen 3 is not deformed, and the bending area 32 is bent into a water droplet shape under the supporting and supporting actions of the first supporting portion 11 and the second supporting portion 12. The first support part 11 is correspondingly supported at the position of the maximum diameter of the water drops of the water drop-shaped bending area 32, namely, the maximum bending position of the inward bending area 321 of the bending area 32 is supported by the first support part 11, and the second support part 12 is correspondingly supported on the first side surface 33 of the flexible display screen 3 between the boundary line 323 and the contact line 324, namely, the position of the inward bending area 321 close to the connection outward bending area 322 is supported by the second support part 12, so that the transition of the inward bending area 321 of the bending area 32 to the outward bending area 322 is gentle under the supporting action of the first support part 11 and the second support part 12, the stretching ratio of the optical cement in the thickness direction of the outward bending area 322 can be effectively reduced, and the problem of the stripping of the optical cement in the prior art is solved.
In a specific implementation, the length from the boundary line 323 of the inward bending area 321 to the first side surface 33 corresponding to the portion of the contact line 324 can be regarded as 1, the length from the middle position between the boundary line 323 of the first side surface 33 and the contact line 324 to the boundary line 323 is 1/2, and simulation results show that the first side surface 33 is supported within the length 1/2, so that the optical cement is prevented from cracking better. The intermediate position between the line of intersection 323 of the first side face 33 and the line of contact 324 is taken as a first support line and the line of support of the second support part 12 and the first side face 33 is preferably arranged between the line of intersection 323 and said first support line.
In a specific implementation, the first body 1 includes a connection area 13 and a support area 14, the connection area 13 is connected to the first side surface 33 corresponding to the fixing area 31, the support area 14 is curved, a cross-sectional thickness of the support area is smaller than a cross-sectional thickness of the connection area 13, and the first support portion 11 and the second support portion 12 are disposed in the support area 14; the first body 1 and the second body 2 have the same structure, and when the first body 1 and the second body 2 are rotatably engaged, the support region 14 of the first body 1 and the second body 2 forms a space for accommodating the droplet-shaped bending region 32.
Specifically, both the first body 1 and the second body 2 may be flat plates, the connection area 13 and the support area 14 of the first body 1 are both located on one side surface of the first body 1, the side surface is a side surface opposite to the side surface when the first body 1 and the second body 2 are buckled, one side of the support area 14 is connected to the connection area 13, the other side of the support area is located at one end of the first body 1, the end of the first body 1 is an end rotatably connected to the second body 2, the support area 14 is curved, so as to form the first support portion 11 and the second support portion 12, and the specific structure of the curved surface is not limited. The second body 2 has the same structure as the first body 1, and is not described herein.
Further, the first body 1 may be provided with the above-mentioned connecting area 13 and the supporting area 14 on one side of the housing, and when the structure inside the housing of the first body 1 is required, the structure also needs to be adaptively arranged according to the shape of the outside of the housing, so that the problem that the device arrangement inside the first body 1 is inconvenient is easily caused. Therefore, as shown in fig. 4, the first body 1 may be provided as a body portion 15 and a holding plate 16 which are separated from each other, and the connecting region 13 and the supporting region 14 may be provided on one side of the holding plate 16, and the other side of the holding plate 16 may be connected to the body portion 15, so that the body portion 15 may be provided in a relatively regular manner, thereby facilitating the arrangement of internal devices. The structure of the second body 2 may be the same as or different from that of the first body 1.

Specifically, dividing the support area 14 into the two areas of the inclined area 141 and the planar area 142 described above can produce the technical effects of facilitating the curved arrangement of the support area 14 and facilitating the manufacturing. It should be noted that, because the water drop shape formed after the bending area of the flexible display screen 3 is bent has the position with the largest water drop diameter corresponding to the position of the plane area 142, the cross-sectional thickness of the inclined area 141 can be set to be greater than the cross-sectional thickness of the plane area 142, so as to ensure that after the first body 1 and the second body 2 are fastened, the accommodating space formed by fastening the supporting area 14 of the first body 1 and the second body 2 can be used for putting down the water drop-shaped bending area 32.
The circular arc protrusion formed on the second side of the inclined plane area 141 may be a continuous approximately semi-cylindrical shape, or may be a plurality of discontinuous semi-cylindrical shapes, wherein a continuous circular arc approximately semi-cylindrical shape is preferred.
Further, it is known from simulation that the included angle R between the surface of the inclined plane region 141 and the first side surface 33 may be 10 to 20 degrees, wherein 10 degrees is preferred, and the effect of preventing the optical cement from cracking is good at this time.
In another specific embodiment, the number of the second supporting portions 12 may be multiple, that is, the supporting region 14 may also include a slant region 141 and a planar region 142, and the slant region 141 and the second side form a plurality of spaced circular arc protrusions to form a plurality of the second supporting portions 12. It should be noted that all the supporting lines of the second supporting portion 12 formed by the circular arc protrusions and the first side surface 33 corresponding to the outer bending area 322 are located between the boundary line 323 of the first side surface 33 corresponding to the outer bending area 322 and the contact line 324.
In a specific implementation, the radius of the circular arc bulge is 1-3mm, and the preferred radius is 2 mm.
