In some embodiments, the first middle frame 10 and the second middle frame 20 can be relatively rotated to any angle of 0-360 °. Namely: the first side 13 and the third side 23 can be selectively moved toward or away from each other during the rotation of the first middle frame 10 relative to the second middle frame 20. And the second side 14 and the fourth side 24 can be selectively close to or away from each other during the rotation of the first middle frame 10 relative to the second middle frame 20.

The flexible laminate tape 70 is attached to the housing assembly 60 on the first side 13 and the third side 23. Referring to fig. 5, the flexible laminated tape 70 includes a buffer layer 75, a first adhesive layer 64 and a second adhesive layer 65, wherein the buffer layer 75 is made of a material having a forming function, and the buffer layer 75 can be made of an elastic material. It is understood that the buffer layer 75 has a deformation function, which means that the buffer layer 75 can be relatively deformed in a transverse direction, wherein the transverse direction refers to a laying direction of the flexible laminated tape 70. The buffer layer 75 has a first connection surface 711 and a second connection surface 721 opposite to each other, and the first connection surface 711 is away from the second connection surface 721. The first adhesive layer 64 is adhered to the first connecting surface 711, and the second adhesive layer 65 is adhered to the second connecting surface 721. The cushioning layer 75 may be made of foam, silicone, TPU plastic, etc.

in some embodiments, cushioning layer 75 may be foam due to its ability to deform. And the foam is of a laminated multi-layer structure, and relative slippage can be generated between every two layers of the laminated structure, so that the foam has the capability of generating relative slippage in the transverse direction. After the flexible laminated adhesive tape 70 is applied, the relative sliding connection between the flexible display screen 80 and the shell assembly 60 can be realized, the foam has a buffering effect, and when the flexible display screen 80 is bent, the foam can absorb partial stress generated in the bending process, so that the flexible display screen 80 is protected more favorably.

Meanwhile, the foam has a plurality of micropore channels, so that the foam has good air permeability. Like this flexible display screen 80 when bonding with flexible stromatolite sticky tape 70 large tracts of land, because there is the bubble in the viscose, do benefit to flexible display screen 80 when buckling, buffer layer 75 can be discharged the gas in the viscose through a plurality of micropore passageways at deformation in-process, make first connection face 711 and flexible display screen 80 when bonding like this, can avoid the unable exhaust of gas between the two to lead to becoming tired gas, in addition, also can reduce and take place the scheduling problem that comes unstuck between first connection face 711 and the flexible display screen 80.

It is understood that the flexible laminated tape 70 may be provided in a form of a stack of a plurality of layers of foam, which may be adhered to each other by, for example, an adhesive, so that the deformability of the flexible laminated tape 70 may be further improved, and the cushioning effect may be improved. It is understood that in some embodiments, the flexible laminate tape 70 may also be made of other materials such as silicone, TPU plastic, and the like. In some embodiments, if the flexible laminated tape 70 is made of a material without a micro-porous structure, the micro-porous channels can be formed on the flexible laminated tape 70 by manual means, for example, by injection molding. In addition, in some embodiments, the first adhesive layer 64 and the second adhesive layer 65 may be a mesh adhesive, which has a mesh structure, so that the mesh adhesive has a higher tensile strength, and at the same time, the mesh adhesive has good air permeability, and can effectively exhaust the gas in the adhesive.

In some embodiments, referring to fig. 6, buffer layer 75 may include first slip layer 71 and second slip layer 72, where first slip layer 71 and second slip layer 72 are disposed in a stacked manner. And first slip layer 71 and second slip layer 72 may produce relative sliding in the lateral direction. The first sliding layer 71 is used for connecting the housing assembly 60, and the second sliding layer 72 is used for connecting the flexible display screen 80.

In this embodiment, the first connecting surface 711 is disposed on the first sliding layer 71, and the second connecting surface 721 is disposed on the second sliding layer. The first sliding layer 71 is adhered to the flexible display 80. The second sliding layer 72 is adhered to the second joint surface 721. In this embodiment, the flexible laminated tape 70 is mounted on the first mounting element 11 and the second mounting element 21, i.e. the second connection surface 721 is adhered to the first mounting surface 111 and the second mounting surface 211.

In the bending process of the flexible laminated tape 70, the first slip layer 71 and the second slip layer 72 cannot be deformed synchronously in the transverse direction due to the different bending radii of the first slip layer 71 and the second slip layer 72, and at this time, the first slip layer 71 and the second slip layer 72 can slide relatively, so that the deformation of the first slip layer 71 and the deformation of the second slip layer 72 are not influenced by each other, thereby realizing the relative sliding between the flexible display screen 80 and the housing assembly 60, and protecting the flexible display screen 80 in the bending process of the flexible display screen 80.

In some embodiments, the buffer layer 75 may further include more than two slip layers, and the more than two slip layers are stacked on top of each other, and the adjacent slip layers may slide relative to each other in the lateral direction.

In some embodiments, at least one of the first connection surface 711 and the second connection surface 721 may be provided with the glue overflow slot 722, and it is understood that the glue overflow slot 722 may be separately provided on the first connection surface 711 or the second connection surface 721. The first connecting surface 711 and the second connecting surface 721 may also be provided with the glue overflow slot 722. It is understood that the glue overflow groove 722 can be formed by the first connection surface 711 and the second connection surface 721 being recessed. The glue overflow slot 722 has the functions of: the adhesive storage amount of the first connecting surface 711 and the second connecting surface 721 can be increased, and meanwhile, excessive adhesive overflow can be avoided.

Referring to fig. 7, in some embodiments, the glue overflow groove 722 may be disposed in a form of a circular groove formed around the edge of the first connection surface 711 or the second connection surface 721, which is advantageous: since the adhesive layer 64 has a certain fluidity, when the adhesive layer 64 is squeezed, the adhesive will flow toward the edge of the first connecting surface 711 or the second connecting surface 721, so that the excessive adhesive overflows into the adhesive overflow groove 722, and the adhesive overflow can be avoided.

In some embodiments, the flash groove 722 may be disposed around the periphery of the first connecting surface 711 or the second connecting surface 721 toward the central portion, for example: the glue-overflow groove 722 of the first connection face 711 may be provided in the form as shown in fig. 8, which provides the advantages of: the flash of glue can be better avoided, and the glue storage amount of the first connecting surface 711 or the second connecting surface 712 can be increased. In addition, the contact area of the first connection surface 711 and the adhesive layer 64 can be increased, thereby increasing the adhesive force between the adhesive layer 64 and the first connection surface 711.

In other embodiments, the position and form of the glue overflow groove 722 may be set according to actual requirements, for example, the cross-sectional shape of the glue overflow groove 722 may be set to any other shape such as U-shape, T-shape, semi-circular shape, rectangular shape, or semi-elliptical shape. In addition, the glue overflow slot 722 can be provided as a plurality of discontinuous slots, and the shape or position of each glue overflow slot 722 can be regular or irregular. In addition, the glue overflow slots 722 can be communicated with each other. It is understood that in some embodiments, the first connection surface 711 and the second connection surface 721 may not be provided with the glue overflow groove 722.

In some embodiments, referring to fig. 9, the flexible laminate tape 70 includes a first flexible laminate tape 73 and a second flexible laminate tape 74, wherein the first flexible laminate tape 73 is attached to the first bezel 10 and adhered to the first mounting surface 111, and the second flexible laminate tape 74 is attached to the second bezel 20 and adhered to the second mounting surface 211. The flexible display 80 is attached to the first and second flexible laminated tapes 73, 74, i.e., the mounting surface 82 of the flexible display 80 is adhered to the first and second flexible laminated tapes 73, 74.

The benefits of this arrangement: the first and second flexible laminate strips 73, 74 are positioned away from the pivotal connection 30 during the bending process so that the pivotal connection 30 moves without interference from the flexible laminate strips 70. In addition, different deformation amounts of the flexible display screen 80 in the first middle frame 10 and the second middle frame 20 can be adapted, for example, when the first middle frame 10 is kept still, the second middle frame 20 rotates relative to the first middle frame 10, the bending deformation of the flexible display screen 80 in the second middle frame 20 is larger than that of the flexible display screen 80 in the first middle frame 10, that is, the flexible display screen 80 can slide relative to the housing assembly 60 by the first flexible laminated adhesive tape 73 and the second flexible laminated adhesive tape 74.

The flexible display screen 80 has a bendable characteristic, and the flexible display screen 80 can be used for image display or man-machine operation. The flexible display 80 is continuously attached to the housing assembly 60 and attached to the flexible laminate tape 70, wherein there is no direct connection between the flexible display 80 and the housing assembly 60. In this embodiment, the flexible display screen 80 includes a display surface 81 and a mounting surface 82 opposite to the display surface 81, and the display surface 81 is exposed for a user to manipulate or view. In this embodiment, the flexible display screen 80 is continuously attached to the first middle frame 10, the second middle frame 20 and the rotation connecting member 30 and located on the first side 13 and the third side 23. Wherein the mounting surface 82 is adhered to the first connection surface 711. In this embodiment, the display surface 81 is flush with the first end surface 124 and the second end surface 224.

In this embodiment, during the relative rotation of the first middle frame 10 and the second middle frame 20 through the rotating connection member 30, the flexible display screen 80 is always exposed, that is, during the selective approaching or departing of the second side 14 and the fourth side 24, the flexible display screen 80 is always located outside the whole electronic device 100 and forms at least a part of an appearance surface of the electronic device 100, and can be operated by a user.

It is understood that in some embodiments, when the flexible display 80 is mounted on the first side 13 and the third side 23, the flexible display 80 may be located inside the electronic device 100 when the flexible display 80 is folded relative to the first middle frame 10 and the second middle frame 20, i.e., when the first middle frame 10 and the second middle frame 20 are in the folded state, the flexible display 80 is not exposed. At this time, the first side 13 and the third side 201 are selectively attached to and detached from each other during the relative rotation of the first middle frame 10 and the second middle frame 20.

When the first middle frame 10 and the second middle frame 20 are relatively rotated to the common plane of the first installation surface 111 and the second installation surface 211, the flexible display screen 80 is in a fully unfolded state; it is understood that when the first mounting surface 111 is not coplanar with the second mounting surface 211, the flexible display 80 is in a bent state. During the bending process, since the first sliding layer 71 and the second sliding layer 72 can slide relatively, the flexible display 80 slides along with the first sliding layer 71 relative to the second sliding layer 72. The benefits of this arrangement: the flexible display screen 80 can be fixed in the housing assembly 60 through the flexible laminated adhesive tape 70, in addition, in the bending process, the sliding between the flexible display screen 80 and the housing assembly 60 can be realized through the deformation of the flexible laminated adhesive tape 70, the flexible display screen 80 is effectively prevented from being stretched in the bending process of the housing assembly 60, in addition, the hard contact between the flexible display screen 80 and the housing assembly 60 can also be avoided, meanwhile, the friction between the flexible display screen 80 and the housing assembly 60 is avoided, and further the service life of the flexible display screen 80 can be prolonged.

In this embodiment, the flexible display 80 is disposed between the first frame 12 and the second frame 22, and gaps 25 are respectively formed between the flexible display 80 and the first frame 12 and between the flexible display 80 and the second frame 22. In the relative rotation process of the first middle frame 10 and the second middle frame 20, when the second side 14 and the fourth side 24 rotate to be relatively close to each other, the gap 25 is arranged, so that the flexible display screen 80 is not connected with the first frame 12 and the second frame 22, and in the bending process of the flexible display screen 80, two ends of the flexible display screen 80 in the transverse direction can be simultaneously far away from the first frame 12 and the second frame 22, so that the flexible display screen 80 is bent to form an arc shape; in addition, when the second side 14 is opposite to and separated from the fourth side 24, the two opposite ends of the flexible display 80 can be close to the first frame 12 and the second frame 22 at the same time, i.e., the gap 25 provides a certain expansion space for the flexible display 60. In addition, during the bending process, due to the existence of the gap 25, the hard contact between the flexible display screen 80 and the housing assembly 60 can be reduced, and the flexible display screen 80 and the housing assembly 60 are prevented from colliding.

In some embodiments, a protective spring washer 26 may be disposed within the gap 25, i.e., the protective spring washer 26 is located between the housing assembly 60 and the flexible display screen 80. The protective elastic pad 26 may be made of a material having an elastic function, and the protective elastic pad 26 may be made of an elastic material such as foam, sponge, silica gel, etc., wherein the protective elastic pad 26 may be adhered to the side of the flexible display 80, or the protective elastic pad 26 may be adhered to the housing assembly 60. Because the edge of flexible display screen 80 is fragile, through setting up protection bullet pad 26, at the in-process of buckling, can effectually avoid the edge of flexible display screen 80 and the direct touching between the casing subassembly 60 to lead to damaging.

In some embodiments, the electronic device may further include a flexible cover 40, the flexible cover 40 being used to provide protection for the flexible display screen 80. Wherein the flexible cover 40 is attached to the display surface 81 of the flexible display 80, i.e. the surface of the flexible display 80 facing away from the flexible laminate tape 70. Wherein the flexible cover 40 and the display surface 81 can be adhered by means of glue. By providing the flexible cover 40, the flexible display screen 80 can be protected, for example, from being scratched or bruised. In the present embodiment, the flexible cover 40 is made of a material having a flexible function, such as: plastic film or bendable glass and the like.

The flexible cover 40 is located on the same side of the flexible display 80 and on the first side 13 and the third side 23, i.e. on the side of the first bezel 12 and the second bezel 22 away from the flexible laminated tape 70. In some embodiments, the flexible cover sheet 40 may be flush with the first end face 124 and the second end face 224. The advantages of such an arrangement are: the flexible cover 40 and the housing assembly 60 can be kept flush and beautiful, and in addition, the flexible display 80 has a larger display area under the condition that the size of the flexible display 80 is ensured, wherein the display area refers to the area of the flexible display 80 which can be directly and visually observed by a user.

referring to fig. 2, in some embodiments, the flexible cover 40 may protrude from the first frame 12 and the second frame 22, that is, the flexible cover 40 protrudes from the first end surface 124 and the second end surface 224 in the direction toward the first side 13 and the third side 23, and has a gap with both the first end surface 124 and the second end surface 224, that is, the flexible cover 40 is not connected to the housing assembly 60, so that the flexible cover 40 slides freely relative to the first frame 12 and the second frame 22 during the bending process, and is not interfered by the first frame 12 and the second frame 22.

At this time, the housing assembly 60 may further include a decoration 50, wherein the decoration 50 may be used to cover the edge of the flexible cover 40 for decoration and beauty. Meanwhile, the electronic device 100 can be prevented from directly colliding with the ground during falling, and damage can be avoided. The decoration 50 is installed on the first middle frame 10 and the second middle frame 20 and is on the same side as the flexible display screen 80.

in some embodiments, referring to fig. 10, the decoration 50 includes a covering portion 54 and a fixing portion 53, wherein the fixing portion 53 is enclosed in a substantially frame shape and is continuously disposed on the first sub-frame 121, the second sub-frame 122, the third sub-frame 123, the fourth sub-frame 221, the fifth sub-frame 222 and the sixth sub-frame 223. The cover portion 54 is connected to the fixing portion 53, and forms a fitting gap 55 with the housing component 60, that is, the cover portion 54 forms the fitting gap 55 with the first end surface 124 and the second end surface 224.

In some embodiments, the width of the assembly gap 55 may be greater than or equal to the thickness of the flexible cover 40 so that the flexible cover 40 may extend into the assembly gap 55. The assembly gap 55 is accessible by the flexible cover 40, and it is understood that the end of the flexible cover 40 parallel to the rotational connection 30 may extend at least partially into the assembly gap 55, i.e., the portion of the flexible cover 40 protruding beyond the flexible display 80 extends into the assembly gap 55. The assembly gap 55 provides a sliding space for the flexible cover 40, so that when the first middle frame 10 and the second middle frame 20 rotate relatively, the flexible cover 40 slides relative to the housing assembly 60 and is shielded by the shielding portion 54 and is invisible to the outside, thereby preventing the user's attention from being shifted to the size change of the gap generated by the flexible cover 40 and the relative sliding between the flexible display 80 and the housing assembly 60. In addition, the portion of the flexible cover 40 extending into the assembly gap 55 is not connected to the trim piece 50 and is not connected to the housing assembly 60. So that the flexible cover 40 will not be pulled or interfered with the housing assembly 60 or the decoration 50 during sliding with the flexible display 80. The decorative element 50 may be looped and integrally attached to the housing member 60.
