Description

Folding screen device

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to a folding screen device.

Background

With the explosive growth of electronic devices, the functions of electronic devices are increasing. The display screen of the electronic device is used to present image information to the user. In some use scenarios, a user desires that the display of the electronic device have a larger display area. Currently, electronic devices are displayed on a single screen, and a larger display area means that the electronic device is larger in size, so that the portability of the electronic device is lost.

In order to balance the size and display area of the electronic device, the electronic device may employ a folder type structure. For example, the two frames may be relatively rotatable about a rotational axis in the rotational axis assembly. And covering the two frames with flexible display screens. When the two frames rotate to the same plane around the rotating shaft, the flexible display screen is in an unfolding state and has a larger display area. When the two frames rotate around the rotating shaft to be mutually folded, the flexible display screen is in a folded state, and the electronic equipment has a small volume. Electronic devices are arranged in the two frames. The electronic devices in the different frames are electrically connected by flexible electrical connection wires spanning the rotational axis.

In order to accommodate the morphological changes in the folding and unfolding of the electronic device, the flexible electrical connection lines need to have redundant lengths. When the two frames are in a folded state, the flexible electrical connection wire can be in a tensed state. When the two frames are in the unfolded state, the flexible electric connecting wire is in a loose and free state, and length redundancy is generated. However, when the electronic device is folded and unfolded each time, the flexible electrical connection wire presents different bending states, and the problem that the bending angle is too small to cause bending broken lines easily occurs.

The electric connection wire passes through the rotating shaft assembly. When the two frames are switched between the folded state and the unfolded state, the form of the electrical connection line is changed. When the two frames are in the unfolded state, the electric connecting wires generate length redundancy and are in a free bending state. However, for each folding and unfolding of the frame body, the electric connecting wires can be in different bending states, so that the electric connecting wires are easy to have the problems of abrasion and wire breakage caused by too small bending radius, the electric connecting wires are invalid, and the electronic equipment is failed.

The folding screen equipment that this embodiment provided can guide the design to the form variation of electric connecting wire to can effectively absorb the redundant length of electric connecting wire, be favorable to the framework at every turn folding, when expanding, electric connecting wire bending state can keep unanimous, reduces the electric connecting wire and appears bending radius and undersize and lead to electric connecting wire to take place wearing and tearing or broken wire's possibility. The following describes the realizations provided by embodiments of the present application.

Fig. 1 schematically shows a structure of an unfolded state of a folding screen apparatus 10 of an embodiment. Fig. 2 schematically shows the structure of the folding screen apparatus 10 in a semi-folded state. Fig. 3 schematically shows the structure of the folding screen apparatus 10 in a folded state. Referring to fig. 1-3, the folding screen apparatus 10 includes a housing 20 and a flexible display screen 30. The housing 20 includes a rotary shaft assembly 21 and a frame 22. The frame 22 is rotatably connected to the rotating shaft assembly 21. The opposite sides of the rotating shaft assembly 21 are respectively provided with a frame 22. The flexible display screen 30 is attached to the housing 22.

The frame 22 can rotate and turn over relative to the rotating shaft assembly 21. In this application, the folding screen apparatus 10 is described by taking an example in which two housings 22 are included. When the two housings 22 are stacked on each other, the folding screen apparatus 10 is in a folded state. When the two frames 22 are away from each other from the stacked state and are unfolded to the same plane, the folding screen apparatus 10 is in the unfolded state. The frame 22 is unfolded from the folded state to the unfolded state, and folded from the unfolded state to the folded state.

Fig. 4 schematically shows a partially exploded structure of the folding screen apparatus 10 of the present application. Referring to fig. 4, the flexible display screen 30 includes a display portion for displaying image information. When the folding screen apparatus 10 is in the unfolded state, the display portion of the flexible display screen 30 is unfolded so as to present image information to the user. The display section includes a first display area 31, a second display area 32, and a third display area 33. The first display area 31 and the second display area 32 are provided corresponding to the two housings 22, respectively. The third display area 33 is disposed corresponding to the spindle assembly 21. The flexible display screen 30 has bending performance and can be folded after being acted by external force.

When the two housings 22 are in the folded state, the display portion is in the folded state. The first display area 31 and the second display area 32 of the display section are stacked on each other, and the third display area 33 may be bent into an arc-shaped state.

When the two frames 22 are in the unfolded state, the display portion is in the unfolded state, and the first display area 31, the second display area 32, and the third display area 33 are in the flat state. When the display portion of the flexible display 30 is in the unfolded state, the whole has good flatness.

The folding screen device 10 can change its overall size by folding or unfolding, and can have a larger display area in the unfolded state.

As shown in fig. 4, the two housings 22 of the folding screen apparatus 10 may be provided with electronic devices 80, respectively, for example, the electronic devices 80 may include, but are not limited to, a processor, a memory, or a camera module. The folding screen apparatus 10 also includes electrical connection wires 40. An electrical connection wire 40 is disposed through the spindle assembly 21. The two ends 41 of the electrical connection wire 40 are disposed in the frame 22 at both sides of the rotating shaft assembly 21. Illustratively, opposite ends 41 of the electrical connection wire 40 are respectively connected to the frame 22 on opposite sides of the spindle assembly 21. The connection of the end 41 of the electrical connection wire 40 to the housing 22 may be that the end 41 of the electrical connection wire 40 is directly connected to the housing 22, or that the end 41 of the electrical connection wire 40 is connected to another structural member in the housing 22, so as to be indirectly connected to and fixed in the housing 22 through the structural member. The respective electronics 80 in the two housings 22 may be electrically connected by electrical connection wires 40 to transmit electrical signals. In some examples, a printed circuit board 70 (Printed Circuit Board, PCB) is disposed within the housing 22. The electronic device 80 is disposed on the printed circuit board 70. The electrical connection lines 40 may be electrically connected to the printed circuit board 70. The ends 41 of the electrical connection wires 40 may be indirectly secured within the housing 22 via a printed circuit board 70.

In some implementations, the electrical connection lines 40 may include a flexible circuit board (Flexible Printed Circuit, FPC). The flexible circuit board may include a plurality of traces for transmitting a plurality of different electrical signals. In some examples, the electrical connection lines 40 may include more than two flexible circuit boards. More than two flexible circuit boards are stacked on each other. More than two flexible circuit boards may be connected at respective ends, while respective other areas may be free of connection.

In some implementations, the electrical connection wire 40 may include at least one single, independently disposed cable. The cable may be used to electrically connect two electronic devices 80 disposed within the two housings 22, respectively.

Fig. 5 schematically shows a partially cut-away structure of a folding screen apparatus of the related art. Referring to fig. 5, the electrical connection wire 40 itself is a flexible structure. When the position of the frame 22 changes, the electrical connection wire 40 may be deformed accordingly. When the two housings 22 are in the folded state, the electrical connection wire 40 may be in a taut state. Fig. 6 schematically shows a partially cut-away structure of a folding screen apparatus of the related art. Referring to fig. 6, when the frame 22 is in the unfolded state, the electrical connection wire 40 may become loose and redundant in length, and thus free bending deformation may occur itself, so that a bending region with a smaller bending radius may easily occur in the electrical connection wire 40.

Fig. 7 schematically shows a partially cut-away structure of the folding screen apparatus 10 of the present application. Referring to fig. 7, the housing 20 further includes a receiving portion 23. The housing 23 is provided on the rotary shaft assembly 21 and the frame 22. The accommodating portion 23 penetrates the rotating shaft assembly 21 and extends into the frame 22, so that the accommodating portion 23 can form a routing channel. At least part of the electrical connection wire 40 is located within the receiving portion 23. An electrical connection wire 40 is disposed through the spindle assembly 21. The folding screen apparatus 10 also includes a styling member 50. The setting member 50 is disposed in the receiving portion 23 and is connected to the housing 20. At least part of the styling member 50 is located between the housing 20 and the electrical connection wire 40. The shaping member 50 serves to guide shaping of the portion of the electrical connection wire 40 located in the receiving portion 23. The setting member 50 may be provided at a surface of the housing 20 facing the receiving portion 23. When the two frames 22 are switched from the folded state to the unfolded state, the shaping member 50 can guide and shape the shape change of the electrical connection wire 40 during bending, so that the electrical connection wire 40 can deform towards the expected bending state. In addition, the shaping member 50 may be abutted against the electrical connection wire 40, so that the corresponding area on the electrical connection wire 40 forms a bending area, thereby increasing the number of bending areas on the electrical connection wire 40, and then absorbing the redundant length of the electrical connection wire 40.

In the folding screen apparatus 10 of the embodiment of the present application, the two ends 41 of the electrical connection wire 40 are respectively disposed in the two frames 22. An electrical connection wire 40 is disposed through the spindle assembly 21. At least a portion of the electrical connection wire 40 is located within the receptacle 23 of the housing 20. The folding screen apparatus 10 further includes a setting member 50 disposed in the receiving portion 23. When the two housings 22 are switched from the folded state to the unfolded state, the electrical connection lines 40 are redundant in length. The shaping member 50 may guide the shaping of the portion of the electrical connection wire 40 located in the receiving portion 23 such that the electrical connection wire 40 may be deformed toward a desired bent state. The shaping member 50 may contact the electrical connection wire 40 such that the corresponding region of the electrical connection wire 40 forms a inflection region, increasing the number of inflection regions, thereby absorbing the redundant length of the electrical connection wire 40. Therefore, when the two frames 22 are folded and unfolded each time, the bending state of the electric connection wire 40 can be kept consistent under the guiding and shaping effect of the shaping component 50, and the shaping component 50 can absorb the redundant length of the electric connection wire 40, so that the bending radius of a bending area formed on the electric connection wire 40 is increased, the possibility that the electric connection wire 40 is worn or broken due to the fact that the electric connection wire 40 is bent and deformed randomly due to the length redundancy and the bending radius is too small is reduced, and the reliability of the electric connection wire 40 and the folding screen device 10 is improved.

In some usage scenarios, for example, the folding screen device 10 is generally in a folded state when the folding screen device 10 is in a carrying state, such that the overall thickness dimension of the folded state of the folding screen device 10 has a large impact on the convenience and experience of the usage process. The setting part 50 that this folding screen device 10 set up can guarantee in limited space that electric connection line 40 forms the great district of buckling of radius to can be favorable to reducing the thickness of folding screen device 10 under the circumstances that electric connection line 40 crooked form satisfies the requirement, in order to promote folding screen device 10's convenience and experience.

In some implementations, since the electrical connection wire 40 may contact the surface of the shaped member 50 facing the electrical connection wire 40, after the contact, there is a compressive stress between the shaped member 50 and the electrical connection wire 40. The surface of the shaping member 50 facing the electrical connection line 40 may be curved. Therefore, when the shaping member 50 contacts the electrical connection wire 40, the contact area between the shaping member 50 and the electrical connection wire 40 is smoothly transited, which is favorable for dispersing the compressive stress existing between the shaping member 50 and the electrical connection wire 40, and reduces the possibility that the shaping member 50 generates stress concentration to generate breakage or disconnection of the electrical connection wire 40 due to the local application of large pressure to the electrical connection wire 40. When the electrical connection wire 40 contacts the shaping member 50, the surface of the shaping member 50 facing the electrical connection wire 40 can better guide the electrical connection wire 40 to bend, so as to form a bending region with a larger bending radius.

In some examples, the surface of the shaping member 50 facing the electrical connection wire 40 is arcuate. Illustratively, the surface of the styling member 50 facing the electrical connection wire 40 includes a plurality of arcuate surfaces. And the arc surfaces are in smooth transition.

In some implementations, the surface of the spindle assembly 21 facing the receptacle 23 is provided with a shaped member 50. The shaping members 50 protrude toward the receiving portion 23 so that portions of the electrical connection lines 40 at the shaft assembly 21 may form bending regions under the guiding of the protruding shaping members 50 to absorb the redundant length generated by the electrical connection lines 40. The portion of the electrical connection wire 40 located in the rotating shaft assembly 21 is in a free state, that is, the electrical connection wire 40 is in a non-connection state with the rotating shaft assembly 21, so that the electrical connection wire 40 is not constrained by the pulling of the rotating shaft assembly 21, and the portion of the electrical connection wire 40 located in the rotating shaft assembly 21 is easy to change in shape along with the folding or unfolding of the frame 22.

In some examples, referring to fig. 7, the spindle assembly 21 includes a spindle cover 211. The shaft cover 211 may be located between the two frames 22. The shaft cover 211 can shield other structural components inside the rotating shaft assembly 21, so that the appearance of the electronic equipment is neat and attractive. The position of the shaft cover 211 can be kept relatively fixed when the two frames 22 are rotated relative to the rotating shaft assembly 21. In some examples, when the two frames 22 are in the expanded state, the two frames 22 may conceal the shaft cover 211 such that the shaft cover 211 is in the invisible state. When the two frames 22 are in the folded state, at least part of the shaft cover 211 can be exposed to the two frames 22 to be in a visible state.

The electrical connection wires 40 are disposed across the shaft cover 211. The two ends 41 of the electrical connection wire 40 are located on either side of the shaft cover 211. The setting member 50 may be provided to an inner wall of the shaft cover 211 facing the receiving portion 23. The setting member 50 is disposed between the shaft cover 211 and the electrical connection wire 40. The shaping member 50 is used for guiding and shaping the portion of the electrical connection wire 40 located in the shaft cover 211, so that the electrical connection wire 40 forms a bending region under the action of the shaping member 50. The electrical connection lines 40 may form a bending region with a large radius in a limited space at the shaft cover 211 to absorb the redundant length generated by the electrical connection lines 40.

In some examples, fig. 8 schematically illustrates a partial cross-sectional structure of the folding screen apparatus 10 of the present application. Referring to fig. 8, the shaft cover 211 may include a recess 211a. The recess 211a of the shaft cover 211 is formed as a part of the space of the accommodation portion 23. Since the shaft cover 211 includes the recess portion 211a, the space of the accommodating portion 23 at the shaft cover 211 is large, so that a portion of the electrical connection wire 40 can be accommodated in the recess portion 211a of the shaft cover 211 in a curved form when the frame 22 is in the unfolded state. The shaping member 50 may guide the shaping of the electrical connection wire 40 such that the electrical connection wire 40 may be received in the recess 211a of the shaft cover 211 in a desired bent configuration.

In some examples, the rounded transition between the surface of the shaped member 50 facing the electrical connection wire 40 and the inner wall of the shaft cover 211 provides a gentle, smooth transition between the shaped member 50 and the shaft cover 211, reducing the likelihood that the electrical connection wire 40 will be susceptible to structural failure or scoring due to the presence of sharp raised structures between the shaped member 50 and the shaft cover 211.

In some examples, a middle portion of the electrical connection wire 40 is located within the shaft cover 211. When the frame 22 is switched from the folded state to the unfolded state, the electrical connection wire 40 is redundant in length, and the intermediate portion of the electrical connection wire 40 moves toward the intermediate region 211b of the shaft cover 211 due to the stress in itself. Accordingly, the middle region 211b of the shaft cover 211 is provided with the fixing member 50 such that the middle portion of the electrical connection wire 40 can be brought into contact with the fixing member 50 earlier, and the middle portion of the electrical connection wire 40 forms a bending region having a large radius by the fixing member 50 to absorb the redundant length of the electrical connection wire 40, so that the bending region having a large radius can be formed between the middle portion of the electrical connection wire 40 and the portions located at both sides of the middle portion.

In some examples, fig. 9 schematically illustrates a partial cross-sectional structure of the folding screen apparatus 10 of the present application. As shown in fig. 9, the shaft cover 211 is provided with the shaping members 50 at both edge regions 211c located on both sides of the intermediate region 211 b. The setting member 50 provided in the edge region 211c may be provided near the opening of the recess 211 a. The shaped member 50, which is disposed relative to the intermediate region 211b, may be closer to the end 41 of the electrical connection wire 40. The shaping members 50 provided in the middle region 211b and the edge region 211c can guide shaping of the portion of the electrical connection wire 40 located at the shaft cover 211, further allowing the electrical connection wire 40 to deform toward a desired bent configuration. The shaping members 50 disposed in the middle region 211b and the edge region 211c can form bending regions in corresponding regions on the electrical connection line 40, which is favorable for further increasing the number of bending regions, so as to absorb the redundant length of the electrical connection line 40 in a limited space more and increase the radius of each bending region, thereby being favorable for further reducing the thickness of the folding screen device 10, and being not easy to cause the problem that the space of the accommodating part 23 is compressed due to the reduced thickness of the folding screen device 10, so that the redundant length of the electrical connection line 40 is too large and the radius of the bending region is too small.

In some examples, the arcuate transition between the shaping members 50 and the shaft cover 211 results in an arcuate recess between the shaping members 50 disposed in the middle region 211b and the shaping members 50 disposed in the edge region 211 c. A portion of the electrical connection wire 40 may be located within the arcuate recess.

In some examples, referring to fig. 9, the electrical connection lines 40 comprise more than two flexible circuit boards. More than two flexible circuit boards are laminated. During the unfolding of the frame 22, delamination between the flexible circuit boards may occur if the flexible circuit boards are not uniformly bent. When the layered flexible circuit boards are mutually attached again, the problem that the folding screen device 10 generates abnormal sound due to mutual beating is easy to occur, and user experience is affected. The shaping component 50 arranged in the middle area 211b and the edge area 211c can effectively limit the movable space of each flexible circuit board, and the shaping component 50 can guide and shape the bending form of each flexible circuit board in the unfolding process of the frame 22, so that the redundant length of each flexible circuit board is absorbed in the same form, the change trend of the bending form of each flexible circuit board is kept consistent, the possibility of layering among each flexible circuit board caused by inconsistent bending forms of each flexible circuit board is reduced, and the problem of abnormal sound caused by the mutual beating of the flexible circuit boards is further solved. In some examples, the shaping member 50 may be a bar-shaped structure extending in the width direction of the flexible circuit board, so that the flexible circuit board as a whole may be sufficiently guided in the width direction of the flexible circuit board.

In some examples, the middle region 211b may be provided with one shaping member 50, and the edge regions 211c on both sides may be provided with one shaping member 50, respectively, i.e., three shaping members 50 are provided on the shaft cover 211. It will be appreciated that the intermediate region 211b and the edge region 211c may be provided with other numbers of styling members 50, as not specifically limited in this application.

In some examples, the protruding height of the shaping member 50 disposed in the middle region 211b is greater than the protruding height of the shaping member 50 disposed in the edge region 211c, so that, on one hand, the shaping member 50 disposed in the edge region 211c may occupy less space, so that there is enough receiving space at the shaft cover 211 to receive the electrical connection wire 40; on the other hand, if the protruding height of the shaping member 50 provided in the edge region 211c is too high, there is a possibility that the electrical connection wire 40 is pressed by the shaping member 50 provided in the edge region 211c, resulting in that the electrical connection wire 40 fails to make contact with the shaping member 50 provided in the intermediate region 211b or the contact area is small, thereby resulting in that the shaping member 50 provided in the intermediate region 211b fails to function effectively, and the solution of the present embodiment may be advantageous in reducing the possibility of occurrence of the above-mentioned problem.

In some examples, the shape and size of each of the shaped members 50 disposed in the two side edge regions 211c may be the same, so that uniformity of the bending form of the electrical connection wire 40 in the region corresponding to the two side shaped members 50 may be improved, and uniformity of the radius of the bending region formed by the electrical connection wire 40 in the region corresponding to the two side shaped members 50 may be improved.

In some examples, the shaft cover 211 and the sizing component 50 are an integrally formed structure. The connection strength between the shaft cover 211 and the shaping member 50 is high, so that the shaping member 50 is not easily separated from the shaft cover 211 when the electric connection wire 40 applies force to the shaping member 50. In addition, the shaft cover 211 and the shaping member 50 can be manufactured simultaneously, which is beneficial to reducing the procedures of later assembly and improving the production efficiency.

In some examples, referring to fig. 9, the setting member 50 provided in the intermediate region 211b may protrude from the bottom wall of the shaft cover 211 by a height H1. The height from the bottom wall to the top end surface of the shaft cover 211 may be H2. Wherein H1 is more than or equal to 0.5 and less than 0.5H2. Illustratively, the H2 may range from 1 millimeter to 4 millimeters.

In some examples, fig. 10 schematically illustrates a partial cross-sectional structure of a folding screen apparatus 10 of the present application. Referring to fig. 10, the shaping member 50 may be a flexible member. The setting member 50 is connected to the shaft cover 211. Illustratively, the sizing member 50 may be adhered to the inner wall of the shaft cover 211, for example, the sizing member 50 may be adhered to the inner wall of the shaft cover 211 by an adhesive or double-sided tape. The flexible shaping member 50 has good softness, so that when the electric connection wire 40 contacts with the shaping member 50, abrasion is not easy to occur between the shaping member 50 and the electric connection wire 40, and the possibility of structural damage or broken wire failure of the electric connection wire 40 caused by long-term abrasion of the shaping member 50 on the electric connection wire 40 is reduced. Illustratively, the material of the sizing component 50 may be foam.

In some implementations, referring to fig. 10, the frame 22 includes a screen support plate 221 and a flexible guard 222. The flexible display screen 30 is disposed on the screen support plate 221. The screen support plate 221 serves to provide a support force for the flexible display screen 30, preventing the flexible display screen 30 from collapsing. When the frame 22 is in the unfolded state, the two screen support plates 221 can maintain the flexible display screen 30 in a flat state. The flexible guard 222 is disposed on a surface of the screen support plate 221 facing the electrical connection line 40. The flexible display screen 30 and the flexible guard 222 are disposed on opposite sides of the screen support plate 221, respectively. The flexible guard 222 is disposed facing the spindle assembly 21. The electrical connection wire 40 is disposed between the spindle assembly 21 and the flexible guard 222. When the electrical connection wire 40 is bent and deformed, the electrical connection wire 40 can be contacted with the flexible protection piece 222, and the flexible protection piece 222 can play a role in buffering and protecting the electrical connection wire 40, so that the possibility that the electrical connection wire 40 is damaged due to the fact that the electrical connection wire 40 is directly contacted with a sharp corner structure existing on the screen support plate 221 is reduced. In some examples, the material of the flexible guard 222 may be foam.

In some realizable forms, fig. 11 schematically shows a partial cross-sectional structure of the folding screen of the present application. As shown in fig. 11, the surface of the frame 22 facing the accommodating portion 23 is provided with a shaping member 50. The space of the accommodation portion 23 inside the housing 22 can accommodate the electrical connection wire 40. The shaping member 50 serves to guide shaping of the portion of the electrical connection wire 40 located at the frame 22. The shaped member 50 provided on the housing 22 is closer to the end 41 of the electrical connection wire 40. When the frame 22 is switched from the folded state to the unfolded state, the portion of the electrical connection wire 40 located in the frame 22 is subjected to length redundancy, and the portion of the electrical connection wire 40 located in the frame 22 is subjected to bending deformation under the action of stress in itself. Therefore, the shaping member 50 disposed on the frame 22 can bend the corresponding region of the electrical connection wire 40 and form a bending region with a larger radius, so as to absorb the redundant length of the electrical connection wire 40, and the shaping member 50 can guide the electrical connection wire 40 to bend and deform, thereby being beneficial to improving the uniformity of the bending form of the electrical connection wire 40 when repeatedly bending.

In some examples, referring to fig. 11, the frame 22 is provided with a shaped member 50 at each of the regions on both sides of the electrical connection line 40. The electrical connection wires 40 pass between the shaped members 50 on both sides. The shaping members 50 on both sides can guide and shape the portion of the electrical connection wire 40 located at the frame 22, so as to further ensure that the electrical connection wire 40 deforms toward the expected bending shape. The shaping components 50 on both sides can form bending areas in corresponding areas on the electric connection wire 40, which is favorable for further increasing the number of the bending areas, so as to absorb the redundant length of the electric connection wire 40 in a limited space more and increase the radius of each bending area, thereby being favorable for reducing the thickness of the folding screen device 10, and being difficult for compressing the space of the containing part 23 due to the reduction of the thickness of the folding screen device 10, thereby causing the problem that the radius of the bending area is too small due to the overlarge redundant length of the electric connection wire 40.

In some examples, a middle portion of the electrical connection wire 40 is connected to the spindle assembly 21. Illustratively, the intermediate portion of the electrical connection wire 40 is bonded to the spindle assembly 21. For example, the middle portion of the electrical connection wire 40 may be adhered to the shaft assembly 21 by an adhesive or a double-sided tape. The intermediate portion of the electrical connection wire 40 is constrained by the shaft assembly 21 such that the intermediate portion of the electrical connection wire 40 cannot move or bend freely relative to the shaft assembly 21. The shaping member 50 provided on the frame 22 guides and shapes the portion of the electrical connection wire 40 extending from the rotating shaft assembly 21.

In some examples, referring to fig. 11, the housing 20 further includes a support 60. The support 60 is disposed corresponding to the shaft cover 211 of the shaft assembly 21. The intermediate portion of the electrical connection wire 40 may pass between the support 60 and the shaft cover 211. When the frame 22 and the flexible display 30 are in the folded state, the supporting member 60 is used for providing support for the third display area 33 bent on the flexible display 30, so that the third display area 33 bent on the flexible display 30 can take a water drop shape, and the possibility that the third display area 33 of the flexible display 30 has folds or cracks due to too small bending radius is reduced.

In some examples, the frame 22 and the sizing component 50 are an integrally formed structure. The connection strength between the frame 22 and the shaping member 50 is high, so that the shaping member 50 is not easily separated from the frame 22 when the electric connection wire 40 applies a force to the shaping member 50. In addition, the frame 22 and the shaping member 50 can be manufactured simultaneously, which is advantageous in reducing the number of steps in the later assembly and improving the production efficiency.

In some examples, referring to fig. 12, a distance between opposite surfaces of the frame 22 facing the receiving portion 23 may be H0. The protruding height of the shaping member 50 provided on one surface may be H3 and the protruding height of the shaping member 50 provided on the other surface may be H4. The electrical connection lines 40 may be flexible circuit boards. The thickness of the flexible circuit board may be h. The protruding height H3 of the shaping member 50 provided on one surface may be within the range of: 0.5H0 > H3 > 2H. The protruding height H4 of the setting member 50 provided on the other surface may have a range of values: 0.5H0 > H4 > 2H.

In some examples, fig. 13 schematically illustrates a partial cross-sectional structure of the folding screen apparatus 10 of the present application. Referring to fig. 13, the shaping member 50 may be a flexible member. The shaping member 50 is attached to the frame 22. Illustratively, the sizing component 50 may be adhered to the frame 22, for example, the sizing component 50 may be adhered to the frame 22 by an adhesive or double sided tape. The flexible shaping member 50 has good softness, so that when the electric connection wire 40 contacts with the shaping member 50, abrasion is not easy to occur between the shaping member 50 and the electric connection wire 40, and the possibility of structural damage or broken wire failure of the electric connection wire 40 caused by long-term abrasion of the shaping member 50 on the electric connection wire 40 is reduced. Illustratively, the material of the sizing component 50 may be foam.
