In the existing folding display terminal, the edge of the display screen relative to the fixed shaft region is generally open outward, which affects the appearance effect of the folding display terminal, and is easily damaged in the use process due to collision and other problems, reducing the reliability of the folding display terminal. SUMMARY

[0004] In a first aspect, the present application provides an edge protection structure for protecting the edge of a bending area of a display screen. The edge protection structure comprises a hard piece, a connecting piece and a soft rubber piece, the strength of the hard piece is greater than the strength of the soft rubber piece, the soft rubber piece is an elastically deformable piece, and the hard piece is connected with the soft rubber piece through the connecting piece; the soft rubber piece comprises a protection part, the protection part comprises a first surface, a second surface arranged oppositely, and a third surface connected between the first surface and the second surface; the hard piece is located on one side of the first surface of the protection part; the connecting piece comprises a first part and a second part connected with the first part, the first part is connected with the protection part, and the second part is connected with the hard piece; the hard piece is arranged on one side of the bending area of the display screen, and the protection part of the soft rubber piece covers the edge of the bending area.

[0005] In the embodiments of the present application, the edge protection structure comprises a hard part and a soft rubber part. When the edge protection structure of the present application is applied to a folding display terminal, the hard part is arranged on one side of the bending area of the display screen, and the protection part of the soft rubber part covers the edge of the bending area, so that the edge of the bending area of the display screen can be wrapped by the hard part and the soft rubber part of the edge protection structure, avoiding the exposure of the edge of the bending area of the display screen, and improving the appearance effect of the folding display terminal. Moreover, when the folding display terminal is subjected to impact, since the edge of the bending area of the display screen is wrapped by the edge protection structure, the edge protection structure can protect the display screen, avoiding damage to the edge position of the bending area of the display screen due to impact.

[0006] In the embodiments of the present application, the edge protection structure is a structure obtained by combining a hard part and a soft rubber part. The soft rubber part can be bent synchronously with the bending of the bending area of the display screen, thereby protecting the edge of the display screen at all times and avoiding the influence of the edge protection structure on the bending of the bending area of the display screen. Moreover, the edge protection structure further comprises a hard part, which can play a better anti-impact role compared with the soft rubber part, thereby achieving good protection effect on the edge of the bending area of the display screen. In other words, in the present application, the edge protection structure obtained by combining the hard part and the soft rubber part protects the edge of the bending area of the display screen, which can achieve good protection effect on the edge of the bending area of the display screen without affecting the bending performance of the display screen, and can improve the appearance effect of the folding display terminal.

[0007] In some embodiments, the soft rubber part further comprises two fixing parts, and the two fixing parts are respectively connected to two ends of the protection part. Each fixing part is partially connected to the third surface of the protection part.

[0008] In the embodiments of the present application, the soft rubber part further comprises a fixing part. When the edge protection structure is applied to a folding display terminal, the fixing part can be fixed in position relative to the first body and the second body on both sides of the rotating shaft assembly of the folding display terminal. By fixing the relative position of the fixing part, the first body and the second body, the problem that the two ends of the protection part connected to the fixing part are lifted after the protection part is deformed after multiple bending of the display screen can be avoided. Moreover, when the fixing part moves with the first body and the second body, the protection part can be folded with the bending area of the display screen, thereby reducing the acting force between the protection part and the display screen, avoiding damage to the display screen, and improving the reliability of the folding display terminal.

[0009] In some embodiments, the edge protection structure further comprises two extension parts, each of which is connected to an end of the protection part. When the edge protection structure in this embodiment is applied to a folding display terminal, the extension parts at the two ends of the protection part are also fixed, so that the shape of the protection part can be further maintained, and the problem that the two ends of the protection part are raised after the protection part is deformed after being bent multiple times with the display screen can be avoided.

[0010] In some embodiments, the extension part comprises a contact surface connected between the first surface of the extension part and the second surface of the extension part, and the contact surface is smoothly connected with the third surface of the protection part. When the edge protection structure in this embodiment is applied to a folding display terminal, the contact surface of the extension part and the third surface of the protection part are both in contact with the display screen, and the contact surface of the extension part and the third surface of the protection part are smoothly connected, so that the contact surface and the third surface can be prevented from being raised due to a large change in the angle at the connection position, and the raised part generated at the contact surface and the third surface can be prevented from generating a large pressure on the display screen, so that the display screen can be prevented from being damaged due to the pressure of the soft glue part.

[0011] In some embodiments, the extension part comprises a fixed surface opposite to the contact surface, the protection part comprises a fourth surface opposite to the third surface, and the fixed surface is smoothly connected with the fourth surface, so that the fixed surface of the extension part and the fourth surface of the protection part can be prevented from being obviously changed in steps or angle at the connection position, the edge protection structure can be installed on the shaft assembly without high precision, and a good appearance effect of the outer surface of the folding display terminal can be ensured, and the fixed surface of the extension part and the fourth surface of the protection part can be prevented from being obviously changed in steps or angle at the connection position, so that the appearance is not symmetrical due to the low precision of the installation of the edge protection structure on the shaft assembly, or the installation of the first edge protection piece or the second edge protection piece is affected.

[0012] In some embodiments, the extension part and the soft glue part are in an integrated structure, so that the combination between the extension part and the soft glue part is more compact, and the extension part and the soft glue part can be prevented from being easily separated after being bent multiple times with the display screen.

[0013] In some embodiments, the hard part and the second part of the connecting part are in an integrated structure, so that the combination between the hard part and the second part of the connecting part is more compact, and the hard part and the second part of the connecting part can be prevented from being easily separated after being bent multiple times with the display screen.

[0014] In some embodiments, the hard part and the second part of the connecting part are connected by adhesive, screw, solder or buckle, so that the connection between the hard part and the soft glue part is simpler and has lower cost.

[0015] In some embodiments, the first part and the protection part are integrated, so that the combination between the protection part and the first part of the connecting piece is more compact, and the protection part and the first part of the connecting piece are not easily separated after the display screen is bent for many times. When the second part of the connecting piece and the hard piece are also integrated, that is, the hard piece, the soft rubber piece and the connecting piece are integrated, so that the connection between the hard piece and the soft rubber piece is more firm, and the problem that the soft rubber piece is separated from the hard piece after being bent for many times is avoided.

[0016] In some embodiments, the fixed part is embedded with a hard plate, and the strength of the hard plate is greater than that of the soft rubber part. In this embodiment, the strength of the fixed part is enhanced by embedding the hard plate in the fixed part, so that the fixed part is not deformed and stuck in the first body or the second body when the folding display terminal is bent, and the deformation of the fixed part stuck in the first body or the second body does not affect the protection of the edge of the bending area of the display screen by the protection part.

[0017] In some embodiments, the third surface of the protection part of the soft rubber piece is a concave arc surface. In this embodiment, when the bending area of the display screen is bent, the protection part of the soft rubber piece will be bent from the third surface of the protection part to the direction away from the display screen. After the protection part is bent for many times, the protection part is easily deformed plastically, so that the two ends of the protection part are raised away from the display screen. In this embodiment, by designing the third surface of the protection part as a concave arc surface, even if the protection part has an initial deformation towards the display screen, the deformation of the protection part away from the display screen after many bends can be partially neutralized, and the risk of the two ends of the protection part being raised after many bends is reduced.

[0018] In some embodiments, the protection part of the soft rubber piece includes a fourth surface opposite to the third surface, and the protection part of the soft rubber piece is provided with a groove recessed from the third surface to the fourth surface. By providing the groove, the shape of the outer surface of the protection part can be ensured unchanged, so that the folding display terminal has a good appearance effect, and the protection part can be deformed more easily, so that the protection part can better follow the bending deformation of the display screen, and the display screen is not easily damaged by a large force.

[0019] In some embodiments, the soft rubber piece is made of soft rubber material, and the hard piece and the connecting piece are made of metal material. The soft rubber material has the characteristics of softness and elastic deformation, and by using the soft rubber material to make the soft rubber piece, the edge protection structure can protect the edge of the bending area of the display screen, and the edge protection structure does not affect the bending of the bending area of the display screen. The metal material has a certain strength, so that the hard piece can have a good effect of resisting impact and protecting the display screen.

[0020] In a second aspect, the present application also provides a folding display terminal. The folding display terminal comprises a fixed shaft, a display screen and any one of the edge protection structures of the first aspect. The display screen comprises a bending area, and the bending area of the display screen is stacked on the fixed shaft. The display screen comprises a display surface and a side surface intersecting the display surface, and the display surface faces away from the fixed shaft. The edge protection structure comprises a hard piece, a connecting piece and a soft rubber piece. The strength of the hard piece is greater than that of the soft rubber piece. The soft rubber piece is an elastically deformable piece. The hard piece is connected to the soft rubber piece through the connecting piece. The soft rubber piece comprises a protection part. The protection part comprises a first surface and a second surface arranged oppositely, and a third surface connected between the first surface and the second surface. The hard piece is located on one side of the first surface of the protection part. The connecting piece comprises a first part and a second part connected to the first part. The first part is connected to the protection part, and the second part is connected to the hard piece. The hard piece is fixed to the fixed shaft. The hard piece is located on one side of the side surface of the display screen, and the hard piece is located in the length extension direction of the bending area. The protection part of the soft rubber piece is located on the side of the display screen facing away from the fixed shaft, and the protection part covers the edge of the bending area of the display screen.

[0021] In the embodiments of the present application, the hard piece of the edge protection structure is fixed to the rotating shaft assembly. The hard piece is located on one side of the side surface of the display screen, and the hard piece is located in the length extension direction of the bending area. The protection part of the soft rubber piece is located on the side of the edge of the bending area of the display screen facing away from the rotating shaft assembly. Thus, the edge of the bending area of the display screen is wrapped by the hard piece and the soft rubber piece of the edge protection structure, so as to avoid the edge of the bending area of the display screen from being exposed, and improve the appearance effect of the folding display terminal. Moreover, when the folding display terminal is subjected to a collision, since the edge of the bending area of the display screen is wrapped by the edge protection structure, the edge protection structure can protect the display screen, so as to avoid the edge position of the bending area of the display screen from being damaged by the collision.

[0022] In the embodiments of the present application, the edge protection structure is a structure obtained by combining a hard part and a soft rubber part. The soft rubber part can bend synchronously with the bending of the bending area of the display screen, so as to protect the edge of the display screen at all times and avoid the influence of the edge protection structure on the bending of the bending area of the display screen. In addition, the edge protection structure further comprises a hard part, which can play a better anti-collision role compared with the soft rubber part, thereby achieving a good protection effect on the edge of the bending area of the display screen. In other words, in the present application, the edge protection structure obtained by combining the hard part and the soft rubber part protects the edge of the bending area of the display screen, which can achieve a good protection effect on the edge of the bending area of the display screen without affecting the bending performance of the display screen, and can improve the appearance effect of the folding display terminal.

[0023] In some embodiments, the folding display terminal further comprises a first edge protection part and a second edge protection part. The soft rubber part further comprises two fixing parts, and the two fixing parts are respectively connected to the two ends of the protection part. Each fixing part is partially connected to the third surface of the protection part. The two fixing parts are respectively located on the side of the first edge protection part facing the display screen and the side of the second edge protection part facing the display screen, i.e. the two fixing parts of the soft rubber part are pressed by the first edge protection part and the second edge protection part, so as to avoid the problem of plastic deformation of the protection part and the lifting of the two ends after the protection part is folded and unfolded multiple times with the display screen.

[0024] In some embodiments, the folding display terminal further comprises a first main body and a second main body, and the fixing shaft is located between the first main body and the second main body and is rotationally connected to the first main body and the second main body. The display screen further comprises a first fixing area and a second fixing area, and the bending area is located between the first fixing area and the second fixing area. The first fixing area of the display screen is opposite to the first main body and is fixed to the first main body, and the second fixing area of the display screen is opposite to the second main body and is fixed to the second main body. Therefore, when the folding display terminal of the present application needs to be folded, the user applies force to the first main body and the second main body, so that the end of the first main body away from the fixing shaft and the end of the second main body away from the fixing shaft move close to each other, so that the first fixing area of the display screen and the second fixing area of the display screen are folded around the shaft area of the display screen.

[0025] In the embodiments of the present application, the periphery of the first edge protector is fixedly connected with the first main body, and the first edge protector covers the edge of the first fixed area of the display screen, so that the edge of the first fixed area of the display screen is not exposed, and damage to the edge of the first fixed area of the display screen caused by collision or impact is avoided.

[0026] In some embodiments, the soft rubber part further comprises two extension parts, and the two extension parts are respectively connected to the two ends of the protection part. The two extension parts are respectively located on the side of the first edge protector facing the display screen and the side of the second edge protector facing the display screen, i.e., the two extension parts are pressed by the first edge protector and the second edge protector. Because the two extension parts are respectively connected to the two ends of the protection part, the two extension parts are pressed by the first edge protector and the second edge protector, i.e., the two ends of the protection part can be further fixed, so that the shape of the protection part can be further maintained, and the problem of deformation of the protection part after multiple bending with the display screen is avoided.

[0027] In some embodiments, the extension part comprises a contact surface, the contact surface faces the display screen, the contact surface is connected between the first surface of the extension part and the second surface of the extension part, and the contact surface is smoothly connected with the third surface of the protection part. In the embodiments of the present application, the contact surface faces the display screen, and the contact surface of the extension part and the third surface of the protection part are in contact with the display screen during the bending process of the display screen. The contact surface of the extension part and the third surface of the protection part are smoothly connected, which can avoid the position angle of the contact surface and the third surface changing greatly and causing a protrusion, so that the protrusion generated by the contact surface and the third surface does not generate great pressure on the display screen, and the display screen is not damaged by the pressure of the soft rubber part.

[0028] In some embodiments, the extension part comprises a fixing surface opposite to the contact surface, the protection part comprises a fourth surface opposite to the third surface, and the fixing surface and the fourth surface are smoothly connected, so that the position where the fixing surface of the extension part is connected to the fourth surface of the protection part is not obviously stepped or angularly changed, and the edge protection structure can be installed on the shaft assembly without high precision and still ensure that the appearance of the folding display terminal has a good appearance effect. When the position where the fixing surface of the extension part is connected to the fourth surface of the protection part is obviously stepped or angularly changed, the appearance is not symmetrical due to the low precision of the installation of the edge protection structure on the shaft assembly, or the installation problem of the first edge protection piece or the second edge protection piece occurs.

[0029] In some embodiments, the extension part and the soft rubber piece are an integral structure, so that the combination between the extension part and the soft rubber piece is more compact, and the extension part and the soft rubber piece are not easily separated after the display screen is bent for many times.

[0030] In some embodiments, the hard piece and the second part of the connecting piece are an integral structure, so that the combination between the hard piece and the second part of the connecting piece is more compact, and the hard piece and the second part of the connecting piece are not easily separated after the display screen is bent for many times.

[0031] In some embodiments, the hard piece and the second part of the connecting piece are connected by adhesive, screw, solder or buckle, so that the connection between the hard piece and the soft rubber piece is more simple and has lower cost.

[0032] In some embodiments, the first part and the protection part are an integral structure, so that the combination between the protection part and the first part of the connecting piece is more compact, and the protection part and the first part of the connecting piece are not easily separated after the display screen is bent for many times. When the second part of the connecting piece and the hard piece are also an integral structure, i.e., the hard piece, the soft rubber piece and the connecting piece are an integral structure, so that the connection between the hard piece and the soft rubber piece is more firm, and the problem that the soft rubber piece is separated from the hard piece after being bent for many times is avoided.

[0033] In some embodiments, the fixing part is embedded with a hard plate, and the strength of the hard plate is greater than the strength of the soft rubber part. By embedding the hard plate in the fixing part, the strength of the fixing part is enhanced, so that the fixing part is not deformed and stuck in the first main body or the second main body when the folding display terminal is bent, and the protection of the edge of the bending area of the display screen by the protection part is not affected.

[0034] In some embodiments, the third surface of the protection part of the soft rubber piece is a concave arc surface. When the bending area of the display screen is bent, the protection part of the soft rubber piece will bend from the third surface of the protection part to the direction away from the display screen. After the protection part is bent multiple times with the display screen, the protection part is prone to plastic deformation, so that the two ends of the protection part are raised away from the display screen. In this embodiment, by designing the third surface of the protection part as a concave arc surface, even if the protection part has an initial deformation towards the display screen, the deformation of the protection part away from the display screen after multiple bending can be partially neutralized, reducing the risk of the two ends of the protection part being raised after multiple bending.

[0035] In some embodiments, the protection part of the soft rubber piece includes a fourth surface opposite to the third surface, and the protection part of the soft rubber piece is provided with a groove recessed from the third surface to the fourth surface. By providing the groove, the shape of the outer surface of the protection part can be ensured unchanged, so that the folding display terminal has a good appearance effect, and the protection part can be more easily deformed, so that the protection part can better follow the display screen to bend and deform, and is not prone to damaging the display screen by a large force.

[0036] In some embodiments, the soft rubber piece is made of soft rubber material, and the hard piece and the connecting piece are made of metal material. Soft rubber material has the characteristics of softness and elastic deformation. By using soft rubber material to make the soft rubber piece, the edge protection structure can protect the edge of the bending area of the display screen while avoiding affecting the bending of the bending area of the display screen.

[0037] In a third aspect, the application also provides another edge protection structure. The edge protection structure is used to protect the edge of the bending area of the display screen. The edge protection structure includes a hard piece and two rotating shaft pieces, one end of each of the two rotating shaft pieces being rotatably connected to the hard piece. The rotating shaft piece includes a connecting rod and a fixed part, one end of the connecting rod being rotatably connected to the hard piece, and the other end of the connecting rod being connected to the fixed part. The fixed part includes a first surface facing the hard piece, and a limiting protrusion is protruded on the first surface. The limiting protrusion is located at one end of the fixed part away from the connecting rod. The hard piece is arranged on one side of the bending area, and the rotating shaft piece of the soft rubber piece covers the edge of the bending area.

[0038] In the embodiments of the present application, the edge protection structure comprises a hard piece and a rotating shaft piece. When the edge protection structure of the present application is applied to a folding display terminal, the hard piece is arranged on one side of the bending area of the display screen, and the rotating shaft piece covers the edge of the bending area, so that the edge of the bending area of the display screen can be wrapped by the hard piece and the rotating shaft piece of the edge protection structure, avoiding the exposure of the edge of the bending area of the display screen, and improving the appearance effect of the folding display terminal. Moreover, when the folding display terminal is collided, since the edge of the bending area of the display screen is wrapped by the edge protection structure, the edge protection structure can protect the display screen, avoiding the damage of the edge position of the bending area of the display screen caused by collision.

[0039] In the embodiments of the present application, the rotating shaft piece can rotate relative to the hard piece. When the folding display terminal is folded, the rotating shaft piece can rotate relative to the hard piece, so that the edge protection structure can provide protection for the edge of the bending area of the display screen at all times, and can avoid the influence of the edge protection structure on the bending of the bending area of the display screen.

[0040] In some embodiments, the connecting rod comprises a first rod surface facing the hard piece, and there is a gap between the first rod surface and the hard piece, so that when the rotating shaft piece rotates, the connecting rod will not rub against the hard piece, ensuring the smoothness of the rotation of the rotating shaft piece, and avoiding damage caused by friction between the connecting rod and the hard piece.

[0041] In some embodiments, the fixing part further comprises a second surface opposite to the first surface, the second surface is located on the side of the first surface away from the hard piece, and the second surface is in contact with and connected to the first rod surface of the connecting rod, that is, the fixing part is located on the side of the connecting rod facing the hard piece. When the edge protection structure is installed on the folding display terminal, the connecting rod covers the edge of the bending area of the display screen. Since the fixing part is located on the side of the connecting rod facing the hard piece, the fixing part can always be located between the display screen and the frame, ensuring that the limiting protrusions on the fixing part can always be located in the sliding groove on the frame and can slide in the sliding groove.

[0042] In some embodiments, the first surface of the fixing part is coplanar with the surface of the hard piece away from the rotating shaft piece, so that during the folding process of the folding display terminal, the distance between each position of the fixing part and the hard piece and the frame is the same, which can ensure that the frame will not rub against the fixing part or the hard piece during the folding process of the folding display terminal, ensuring the smoothness of the folding of the folding display terminal, and at the same time, the gap between the fixing part and the hard piece and the frame can be minimized.

[0043] In some embodiments, the connecting rod further comprises a second rod surface opposite to the first rod surface, and a third rod surface connected between the first rod surface and the second rod surface, the third rod surface being a plane. When the edge protection structure is mounted on the folding display terminal, the third rod surface is in contact with the display screen of the folding display terminal. Since the third rod surface in contact with the display screen is a plane, the distance between the display screen and the third rod surface can be reduced, while avoiding the protrusion of a certain position of the third rod surface to press against the display screen and damage the display screen, thereby ensuring the quality of the display screen.

[0044] In some embodiments, the hard material comprises a connecting end and a fixed end connected to the connecting end, the connecting rod is connected to the connecting end of the hard material, the fixed part comprises a first end and a second end arranged oppositely, the first end of the fixed part is connected to the connecting rod, the limiting protrusion is arranged on the second end of the fixed part, the second end is closer to a reference plane than the first end, and the reference plane is located on a side of the fixed end away from the connecting end, so as to ensure that the fixed part is always located between the display screen and the frame during folding of the folding display terminal, and ensure that the limiting protrusion located on the fixed part is always located in the sliding groove on the frame and can slide in the sliding groove.

[0045] In some embodiments, the connecting end comprises a first surface and a second surface arranged oppositely; the fixed end comprises a third surface and a fourth surface arranged oppositely, the third surface and the first surface are directed to the same side, and the second surface and the fourth surface are directed to the same side; the first surface and the third surface are arranged non-coplanarly, and the first surface and the third surface are connected by a fifth surface. When the fixed end of the hard material is inserted into the slot of the fixed shaft of the folding display terminal to mount the edge protection structure on the folding display terminal, the fifth surface of the hard material can be in contact with the surface of the fixed shaft, so as to ensure that the fixed end of the hard material can be more stable when inserted into the fixed shaft, and ensure the stable installation of the edge protection structure in the folding display terminal.

[0046] In some embodiments, the width of the fixed end is smaller than the width of the connecting end, and the width direction of the fixed end is the same as the width direction of the connecting end, both being perpendicular to the direction from the first surface to the second surface. When the fixed end of the hard material is inserted into the slot of the fixed shaft of the folding display terminal to mount the edge protection structure on the folding display terminal, the part of the connecting end beyond the fixed end in the width direction abuts against the surface of the fixed shaft, which can further ensure that the fixed end of the hard material can be more stable when inserted into the slot of the fixed shaft, and is less likely to shake and fall off.

[0047] In some embodiments, the end surface of one end of the connecting rod connected with the hard piece is a circular arc surface, and the end surface is provided with engagement teeth, and the engagement teeth on the end surfaces of the two connecting rods are engaged. When one of the rotating shaft pieces is rotated, the other rotating shaft piece of the edge protection structure can be synchronously rotated due to the engagement of the engagement teeth on the end surfaces of the two connecting rods, thereby achieving a better rotating experience.

[0048] In some embodiments, the hard piece and the rotating shaft piece are metal pieces, i.e., the edge protection structure has greater strength, can achieve better anti-collision effect, and can achieve better protection effect on the edge of the bending area of the display screen.

[0049] In a fourth aspect, the application further provides another kind of folding display terminal. The folding display terminal comprises a screen support assembly, a display screen and two edge protection structures of any of the embodiments of the second aspect, the display screen is laminated on the screen support assembly; the screen support assembly comprises a first main body, a second main body and a fixed shaft, the fixed shaft is located between the first main body and the second main body; the display screen comprises a first fixed area, a second fixed area and a bending area, the bending area is located between the first fixed area and the second fixed area; the first fixed area is opposite to and fixed with the first main body, the second fixed area is opposite to and fixed with the second main body, and the bending area is opposite to the fixed shaft.

[0050] The hard pieces of the two edge protection structures are respectively fixed to the two ends of the fixed shaft; and the hard pieces of the two edge protection structures are respectively located on opposite sides of the bending area of the display screen, the connecting rod of the edge protection structure is located on the side of the display screen away from the fixed shaft and covers the edge of the bending area of the display screen; the first main body and the second main body each comprise a frame, the frame is arranged around the edge of the display screen, the frame is provided with a sliding groove, and the limiting protrusion on the fixed part of the edge protection structure slides in the sliding groove.

[0051] By fixing the edge protection structure to the rotating shaft assembly and locating the hard piece of the edge protection assembly on one side of the bending area of the display screen, the connecting rod covers the edge of the bending area of the display screen, i.e., the edge of the bending area of the display screen is wrapped by the hard piece and the connecting rod, thereby avoiding the exposure of the edge of the bending area of the display screen, improving the appearance effect of the folding display terminal, and preventing the edge of the bending area of the display screen from being damaged by collision. Moreover, the rotating shaft piece can rotate relative to the hard piece, and when the folding display terminal is folded, the rotating shaft piece can correspondingly rotate relative to the hard piece, so that the edge protection structure can provide protection to the edge of the bending area of the display screen at all times, and the influence of the edge protection structure on the bending of the bending area of the display screen can be avoided.

[0052] In some embodiments of the present application, the track of the sliding groove is designed according to the track of the limiting protrusion of the edge protection structure when the folding display terminal is bent, so that when the folding display terminal is bent, the bending area of the display screen is bent, and when the first body and the second body are folded around the hinge assembly, the limiting protrusion of the hinge member can slide in the sliding groove and drive the hinge member to rotate correspondingly, so that the rotation of the hinge member is always synchronized with the bending of the display screen during the bending process of the folding display terminal, and the display screen does not need to push the hinge member to make it rotate, that is, there is no force between the display screen and the hinge member, thereby avoiding the damage of the display screen caused by the force between the display screen and the hinge member.

[0053] In a fifth aspect, the present application provides another edge protection structure for protecting the edge of the bending area of the display screen. The edge protection structure comprises an elastic sheet and a flexible piece, the elastic sheet comprises a protection section and two fixed sections, the two fixed sections are respectively connected to the two sides of the protection section, and the flexible piece is laminated on the elastic sheet and covers the protection section of the elastic sheet. The elasticity of the elastic sheet is greater than that of the flexible piece, and the flexible piece and the protection section of the spring sheet are used to cover the edge of the bending area.

[0054] When the edge protection structure of the present application is installed on the folding display terminal, the protection section of the elastic sheet and the flexible piece of the edge protection structure are opposite to the bending area of the display screen and cover the edge of the bending area of the display screen, so as to cover the edge of the bending area of the display screen by the edge protection structure, avoid the exposure of the edge of the bending area, and improve the appearance effect of the folding display terminal. At the same time, since the bending area of the display screen is covered by the flexible piece and the protection section of the edge protection structure, when the bending area of the display screen is collided, the flexible piece and the protection section of the edge protection structure can protect the bending area of the display screen, so as to avoid the damage of the edge of the bending area of the display screen due to the collision. In the embodiments of the present application, the elasticity of the elastic sheet is greater than that of the flexible piece, so as to ensure that the edge protection structure will not be deformed greatly after being bent for many times, and the bending life of the edge protection structure is ensured.

[0055] In some embodiments, the flexibility of the elastic sheet is less than that of the flexible piece. The flexibility of the elastic sheet is less than that of the flexible piece, so as to provide good support effect for the flexible piece. Moreover, since the flexible piece has good flexibility, the influence of the flexible piece on the bending performance of the edge protection structure is reduced. Moreover, the flexible piece can achieve good buffering effect, avoid the force generated by the collision being conducted to the display screen through the elastic sheet, and achieve good protection effect on the display screen.

[0056] In some embodiments, the surface of the elastic sheet is smoother than the surface of the flexible piece. In the embodiments of the present application, when the edge protection structure is installed on the folding display terminal, the surface of the elastic sheet is in contact with the display screen. In the embodiments of the present application, the surface of the elastic sheet is relatively smooth, which can reduce the friction between the elastic sheet and the display screen, avoid the elastic sheet and the display screen being pulled due to the friction during the bending of the folding display terminal, and ensure the smooth bending of the folding display terminal, and avoid the damage of the display screen caused by the pulling between the elastic sheet and the display screen, thereby improving the reliability of the folding display terminal.

[0057] In some embodiments, the width of the middle position of the protection section is smaller than the width of the two sides close to the fixed section, so that the bending performance of the middle position of the protection section is better than the bending performance of the two end positions close to the fixed section, the bending position of the edge protection structure is at the middle position of the protection section when the folding display terminal is folded, thereby reducing the bending of the two end positions of the protection section connected with the fixed section, and reducing the pulling of the fixed section. In the embodiments of the present application, the bending performance of the middle position of the protection section is better than the bending performance of the two end positions close to the fixed section, and the middle position of the protection section is opposite to the middle position of the bending area, thereby ensuring that the edge protection structure can be deformed synchronously with the display screen, and the display screen is not damaged by the force.

[0058] In some embodiments, the width of the middle position of the flexible piece is smaller than the width of the two ends close to the fixed section, so that the bending performance of the middle position of the flexible piece is better than the bending performance of the two sides close to the fixed section, and the bending of the flexible piece occurs at the middle position of the flexible piece as much as possible, thereby avoiding the separation of the two ends of the flexible piece from the elastic sheet, avoiding the problem of the two ends of the flexible piece being lifted, and ensuring the appearance effect of the folding display terminal. In the embodiments of the present application, the bending performance of the middle position of the flexible piece is better than the bending performance of the two end positions close to the fixed section, and the middle position of the flexible piece is opposite to the middle position of the bending area, thereby ensuring that the edge protection structure can be deformed synchronously with the display screen, and the display screen is not damaged by the large force.

[0059] In some embodiments, the protection section includes a first surface and a second surface arranged opposite to each other in a width direction, and a notch is formed in a middle position of the first surface towards the second surface, so that the width of the middle position of the protection section is smaller than the width of the two sides of the fixed section, and the bending performance of the middle position of the protection section is better than the bending performance of the two end positions of the fixed section.

[0060] In some embodiments, the thickness of the middle position of the flexible piece is thinner than the thickness of the two ends of the fixed section, so as to further improve the bending performance of the middle position of the flexible piece.

[0061] In some embodiments, the flexible piece includes a third surface and a fourth surface arranged opposite to each other in a thickness direction, and the third surface is away from the elastic sheet relative to the fourth surface, and the third surface is a concave arc surface towards the fourth surface, so that the thickness of the middle position of the flexible piece is thinner than the thickness of the two ends of the fixed section.

[0062] In some embodiments, the width of the fixed section is the same as the width of the protection section, and the width direction of the fixed section and the protection section is perpendicular to the arrangement direction of the fixed section and the protection section. Since the fixed section is connected to the two sides of the protection section, the tension of the protection section can be realized by the fixation of the fixed section. Since the width of the fixed section is basically the same as the width of the protection section, the positions in the width direction of the protection section can be tensioned by the fixation of the fixed section, so as to avoid the problem of warping after multiple bending.

[0063] In some embodiments, the width of the protection section is smaller than the width of the protection piece. In other words, when the protection piece covers the protection section of the elastic sheet, the edges of the protection piece in the width direction protrude out of the edges of the protection section. When the edge protection structure is impacted, the impact force will act on the protection piece. Since the protection piece is a flexible structure with better flexibility than the elastic sheet, it can better buffer the impact force, so as to avoid the impact force acting on the elastic sheet, and then avoid the impact force being transmitted to the display screen to damage the display screen.

[0064] In some embodiments, an adhesive layer is stacked on the fixed section, and the adhesive layer is located on the same side of the flexible piece as the elastic sheet. The adhesive layer includes a glue layer and a release film layer, and the release film layer is located on the side of the glue layer away from the fixed section. By stacking the adhesive layer on the fixed section, the fixed section can be conveniently fixed to the folding display terminal.

[0065] In some embodiments, the elastic sheet and the flexible piece are formed as an integral structure. Specifically, the elastic sheet and the flexible piece can be formed as an integral structure by integral molding such as injection molding, thereby ensuring the stability of the connection between the elastic sheet and the flexible piece.

[0066] In some embodiments, the elastic sheet is a PET sheet, a PI sheet or a metal sheet, and the flexible piece is a rubber piece or a silica gel piece.

At the same time, since the bending area of the display screen is covered by the flexible piece and the protection section of the edge protection structure, when the bending area of the display screen is collided, the flexible piece and the protection section of the edge protection structure can protect the bending area of the display screen, thereby avoiding the damage of the edge of the bending area of the display screen due to the collision.

[0072] When the edge protection structure is installed in the folding display terminal, the second surface of the elastic sheet faces the display screen. In the embodiments of the present application, by covering the second surface of the elastic sheet with the smoothing layer with higher smoothness, when the edge protection structure is installed in the folding display terminal, the smoothing layer is in contact with the display screen, and since the smoothing layer has a relatively smooth surface, the frictional force between the edge protection structure and the display screen can be reduced, thereby ensuring that the bending and unfolding process of the folding display terminal is smoother and avoiding damage to the display screen caused by the frictional force between the elastic sheet and the display screen.

[0100] In the present application, the flexible piece of the edge protection structure can cover the edge position of the bending area of the display screen, avoiding the edge of the bending area to be exposed, thereby improving the appearance effect of the display terminal. At the same time, since the bending area of the display screen is covered by the flexible piece of the edge protection structure, when the bending area of the display screen is collided, the flexible piece of the edge protection structure can protect the bending area of the display screen, thereby avoiding the edge of the bending area of the display screen from being damaged due to collision.

When the edge protection structure is installed in the folding display terminal, the smoothing layer is in contact with the display screen. Since the smoothing layer has a smoother surface, the frictional force between the edge protection structure and the display screen can be reduced, so that the folding and unfolding process of the folding display terminal is smoother, and the display screen is prevented from being damaged due to the frictional force between the fixing block and the display screen.

[0109] In a tenth aspect, the present application further provides a folding display terminal, which comprises a display screen, a rotating shaft assembly, and the edge protection structure of any of the embodiments provided in the ninth aspect.

Detailed Implementation

[0194] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0195] It should be noted that the terms "first," "second," etc., used in this application are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0196] This application provides a foldable display terminal that can display images and also fold to change its size. In this application, the foldable display terminal can be a mobile phone, monitor, tablet computer, in-vehicle computer, or other product with a display interface. This application does not impose any special limitations on the specific form of the foldable display terminal described above. To facilitate understanding of the foldable display terminal provided in this application, a detailed description of the foldable display terminal is provided below with reference to the accompanying drawings.

[0197] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 The diagram shown is a structural schematic of a foldable display terminal 1000 in its unfolded state according to one embodiment of this application. Figure 2 As shown Figure 1 A schematic diagram of the structure of the foldable display terminal 1000 in the embodiment shown when folded to the intermediate state; Figure 3 As shown Figure 1 The illustrated embodiment shows a schematic diagram of the foldable display terminal 1000 in its fully folded state. In this embodiment, the foldable display terminal 1000 is a mobile phone, which can be folded or unfolded to change its size according to actual needs and usage scenarios. For example, when video viewing or file processing is required, the foldable display terminal 1000 can be unfolded to a size such that... Figure 1The folding display terminal 1000 is folded to the state shown in FIG. 10B, thereby increasing the size of the display screen of the folding display terminal 1000, so that better video watching effect or file processing experience can be achieved; when a call needs to be received or made, the folding display terminal 1000 can be folded to the state shown in FIG. 10C, thereby facilitating the user to hold the folding display terminal 1000 and improving the user experience. Figure 3

[0198] Please refer to Figure 4 , Figure 4 The exploded view of the folding display terminal 1000 is shown in FIG. 11. In this embodiment, the folding display terminal 1000 includes a display screen 200, a screen support assembly 300, and an edge protection assembly 1001. The display screen 200 is stacked on the screen support assembly 300, supported by the screen support assembly 300, and driven to fold by the screen support assembly 300. Figure 1

[0199] In this embodiment, the display screen 200 includes a display surface 203 and a side surface 204 intersecting the display surface 203. The display surface 203 is a surface of the display screen 200 for light emission, and the side surface 204 is a surface of the display screen 200 in the thickness direction. In this embodiment, the display screen 200 is an inner folding screen of the folding display terminal 1000, i.e., when the folding display terminal 1000 is folded, the display surface 203 of the display screen 200 is located on the inner side of the folding display terminal 1000. It can be understood that in some other embodiments of the present application, the display screen 200 can also be an outer folding screen of the folding display terminal 1000, i.e., when the folding display terminal 1000 is folded, the display surface 203 of the display screen 200 is located on the outer side of the folding display terminal 1000.

[0200] It should be noted that in this application, the thickness direction of the display screen 200 is the same as the thickness direction of the folding display terminal 1000, both being the Z-axis direction in the coordinate system shown in FIG. 9; Figure 4 The length direction of the display screen 200 is the same as the length direction of the folding display terminal 1000, both being the X-axis direction in the coordinate system shown in FIG. 9; Figure 4 The width direction of the display screen 200 is the same as the width direction of the folding display terminal 1000, both being the Y-axis direction in the coordinate system shown in FIG. 9. Figure 4

[0201] The edge protection assembly 1001 is located at the edge of the display screen 200 and is used to protect the edge position of the display screen 200, avoid the edge of the display screen 200 being open to the outside, so that the folding display terminal 1000 has a better appearance effect, and can avoid damage to the edge of the display screen 200 due to external problems such as collision, thereby improving the reliability of the folding display terminal 1000.

[0202] ​​​In this embodiment, the display screen 200 includes a first fixed area 200a, a second fixed area 200b, and a hinge area 200c connected between the first fixed area 200a and the second fixed area 200b. The first fixed area 200a and the second fixed area 200b are fixed with the screen support assembly 300, so that the display screen 200 is fixed with the screen support assembly 300 and supported by the screen support assembly 300. When the folding display terminal 1000 is folded, the hinge area 200c of the display screen 200 can be bent. In this embodiment, when the folding display terminal 1000 is folded, the bending area of the display screen 200 is the hinge area 200c of the display screen 200. During the folding process of the folding display terminal 1000, the hinge area 200c of the display screen 200 is bent, and the end of the first fixed area 200a away from the bending area 202b and the end of the second fixed area 200b away from the hinge area 200c are close to each other. During the unfolding process of the folding display terminal 1000, the hinge area 200c of the display screen 200 gradually becomes flat, and the end of the first fixed area 200a away from the hinge area 200c and the end of the second fixed area 200b away from the hinge area 200c are away from each other.

[0203] In this embodiment, the hinge area 200c of the display screen 200 includes a bending area 2001 and a connecting area 2002 connected to both sides of the bending area 2001. In this embodiment, the connecting area 2002 is two, and the two connecting areas 2002 are a first connecting area and a second connecting area. The first connecting area and the second connecting area are located on both sides of the bending area 2001, and the first connecting area connects the bending area 2001 and the first fixed area 200a, and the second connecting area connects the bending area 2001 and the second fixed area 200a. In this embodiment, when the folding display terminal 1000 is folded, the bending degree of the bending area 2001 is generally greater than the bending degree of the connecting area 2002. It can be understood that in some embodiments of the present application, the hinge area 200c can only include the bending area 2001, and the opposite sides of the bending area 2001 are connected to the first fixed area 200a and the second fixed area 200a, respectively. Alternatively, in some embodiments, the hinge area 200c includes the bending area 2001 and the connecting area 2002, and the number of connecting areas 2002 can be more than two. Part of the connecting areas in the more than two connecting areas are connected to one side of the bending area 2001 close to the first fixed area 200a, and the other part of the connecting areas are connected to one side of the bending area 2001 close to the second fixed area 200b. For example, in some embodiments, the hinge area 200c includes the bending area 2001 and four connecting areas 2002, two connecting areas 2002 are connected between the bending area 2001 and the first fixed area 200a, and the other two connecting areas 2002 are connected between the bending area 2001 and the second fixed area 200a.

[0204] Please refer toFigure 5 , Figure 5 As shown Figure 4 An exploded view of the display screen 200 according to the illustrated embodiment. Specifically, the display screen 200 includes a flexible screen 201. The flexible screen 201 is used for displaying images and has bendable characteristics. In this embodiment, the flexible screen 201 can be an organic light-emitting diode (OLED) display screen. It is understood that in other embodiments of this application, the flexible screen 201 can also be other screens with bendable properties and capable of displaying images.

[0205] In this embodiment, the display screen 200 may further include a support member 202 for supporting the flexible screen 201. The flexible screen 201 is stacked on the support member 202, meaning the support member 202 provides support for the flexible screen 201, thereby improving the service life of the flexible screen 201 without affecting the bending performance of the display screen 200. In this embodiment, the support member 202 includes two support areas 202a and a bending area 202b connecting the two support areas 202a. The two support areas 202a are respectively located in the first fixed area 200a and the second fixed area 200b of the display screen 200, and the bending area 202b of the support member 202 is located in the pivot area 200c of the display screen 200. The bending area 202b of the support member 202 has better bending performance relative to the support areas 202a, thereby preventing the support member 202 from affecting the bending performance of the bending area 200c of the display screen 200. In this embodiment, the support member 202 is a metal sheet, and a plurality of spaced strip grooves 202c are formed on the bending area 202b of the support member 202. The extending direction of the strip grooves 202c is the same as the length direction of the bending area 200c of the display screen 200 (i.e., Figure 4 (in the Y direction), so that the bending area 202b of the support member 202 has better bending performance than the support area 202a, thereby avoiding the influence of the support member 202 on the bending performance of the bending area 200c of the display screen 200.

[0206] It is understood that in other embodiments of this application, the support member 202 may also be of other structures to achieve a good supporting effect on the flexible screen 201 without affecting the bending performance of the pivot area 200c of the display screen 200. In some embodiments, the display screen 200 may not have the support member 202, that is, the display screen 200 may only include the flexible screen 201, and the support of the flexible screen 201 is achieved by the screen support assembly 300.

[0207] Please refer to the previous document. Figure 4In this embodiment, the screen support assembly 300 comprises a first body 301, a second body 302 and a hinge assembly 303. The hinge assembly 303 is rotatably connected between the first body 301 and the second body 302. The first fixed area 200a of the display screen 200 is opposite to and fixed to the first body 301, the second fixed area 200b of the display screen 200 is opposite to and fixed to the second body 302, and the bending area 202b of the display screen 200 corresponds to the hinge assembly 303. The first body 301 and the second body 302 can be folded with the hinge assembly 303 as the folding position, thereby driving the display screen 200 to fold at the hinge area 200c corresponding to the hinge assembly 303.

[0208] It can be understood that in other embodiments of the present application, the folding display terminal 1000 can further comprise a third body connected between the first body 301 and the second body 302, and the first body 301 and the third body are connected by the hinge assembly 303, and the second body 302 and the third body can be connected by another hinge assembly 303. In some other embodiments of the present application, the folding display terminal 1000 can further comprise a plurality of third bodies connected between the first body and the second body, and the plurality of third bodies can be connected by another hinge assembly 303, so that the folding display terminal 1000 can be folded multiple times.

[0209] In this embodiment, the hinge assembly 303 comprises a fixed shaft 3031 and two rotating shafts 3032, and the two rotating shafts 3032 are respectively located on both sides of the fixed shaft 3031 and are rotatably connected with the fixed shaft 3031. In this embodiment, the axial directions of the fixed shaft 3031 and the rotating shaft 3032 are parallel, and both are in the Y-axis direction shown in FIG. 8. Figure 4 The two rotating shafts 3032 are respectively arranged on both sides of the fixed shaft 3031 in the width direction of the fixed shaft 3031, wherein the width direction of the fixed shaft 3031 is the X direction in FIG. 8, which is perpendicular to the Y-axis direction. Figure 4 In this embodiment, the rotating connection between the fixed shaft 3031 and the rotating shaft 3032 can be achieved by a hinge, a gear or other structures or the cooperation between the structures, which will not be described in detail. Specifically, when the folding display terminal 1000 is folded at the hinge assembly 303, the rotating shaft 3032 will rotate relative to the fixed shaft 3031, thereby achieving the folding of the folding display terminal 1000. It should be noted that during the rotation of the rotating shaft 3032 relative to the fixed shaft 3031, the axial direction of the rotating shaft 3032 is always the same as that of the fixed shaft 3031, and the angle between the rotating shaft 3032 and the fixed shaft 3031 gradually changes.

[0210] Please refer toFigure 4a , Figure 4a As shown Figure 4 An exploded view of the pivot assembly 303 of the illustrated embodiment. In this embodiment, the pivot shaft 3032 of the pivot assembly 303 includes a pivot mechanism 3032a and a door panel 3032b stacked on the pivot mechanism 3032a. The pivot mechanism 3032a is formed by the cooperation of multiple pivoting structures, allowing the pivot shaft 303 to rotate relative to the fixed shaft 3031. The door panel 3032b is a flat plate structure fixed to the pivot mechanism 3032a. The display screen 200 is stacked on the pivot assembly 303, and the display screen 200 is in contact with the door panel 3032b, which supports the display screen 200.

[0211] In this embodiment, the two rotating shafts 3032 are a first rotating shaft and a second rotating shaft, respectively. The first main body 301 of the foldable display terminal 1000 is rotatably connected to the side of the first rotating shaft away from the fixed shaft 3031, and the second main body 302 is rotatably connected to the side of the second rotating shaft away from the fixed shaft 3031. In other words, the first rotating shaft is rotatably connected between the fixed shaft 3031 and the first main body 301, and the second rotating shaft is rotatably connected between the fixed shaft 3031 and the second main body 302. That is, the fixed shaft 3031 is rotatably connected to the first main body 301 via the first rotating shaft, and the fixed shaft 3031 is rotatably connected to the second main body 302 via the second rotating shaft. The rotatable connection between the first main body 301 and the first rotating shaft can be achieved through a rotating shaft, hinge, gear, or other structure, or through the cooperation of various structures; the rotatable connection between the second main body 302 and the second rotating shaft can also be achieved through a rotating shaft, hinge, gear, or other structure, or through the cooperation of various structures. This application will not describe these details here.

[0212] When the first body 301 is folded relative to the second body 302 with the folding assembly 303 as the axis, both the first rotation axis and the second rotation axis can rotate relative to the fixed axis 3031, and the first body 301 can rotate relative to the first rotation axis and the second body 302 can rotate relative to the second rotation axis.

[0213] In this embodiment, the pivot area 200c of the display screen 200 is opposite to the pivot assembly 303. Specifically, the bending area 2001 of the pivot area 200c is opposite to the fixed axis 3031 of the pivot assembly 303, and each connecting area 2002 of the pivot area 200c is opposite to a rotating axis 3032 of the pivot assembly 303.

[0214] In some embodiments of the present application, the connecting area 2002 of the rotation shaft area 200c can be fixed with the rotating shaft 3032 opposite thereto, so as to ensure that the rotating shaft assembly 303 rotates relative to the fixed shaft 3031, and when the rotation shaft area 200c of the display screen 200 is bent, the rotating shaft assembly 303 can better support the rotation shaft area 200c of the display screen 200, so as to avoid damage to the rotation shaft area 200c of the display screen 200 during the bending process. In the present embodiment, the connecting area 2002 of the rotation shaft area 200c can be fixed with the rotating shaft 3032 opposite thereto by means of adhesive bonding. Specifically, in the present embodiment, the first connecting area is opposite to the first rotating shaft and is bonded and fixed with the first rotating shaft by means of adhesive; and the second connecting area is opposite to the second rotating shaft and is bonded and fixed with the second rotating shaft by means of adhesive. It can be understood that in other embodiments of the present application, the connecting area 2002 of the rotation shaft area 200c can also be connected and fixed with the rotating shaft 3032 opposite thereto by means of screw fixing, welding, clamping connection or adhesive fixing, etc., which is not limited in the present application. Alternatively, in other embodiments of the present application, the connecting area 2002 of the display screen 200 and the rotating shaft 3032 can also be unfixed.

[0215] In some embodiments of the present application, the connecting area 2002 of the rotation shaft area 200c is two or more, and the rotating shaft 3032 of the rotating shaft assembly 303 can also be two or more. The connecting area 2002 of the rotation shaft area 200c and the rotating shaft 3032 of the rotating shaft assembly 303 are opposite to each other, i.e., each connecting area 2002 of the display screen 200 is arranged opposite to a rotating shaft 3032. For example, in some embodiments, the rotating shaft 3032 can be four, two rotating shafts 3032 are rotatably connected between the fixed shaft 3031 and the first main body 301, and the other two rotating shafts 3032 are rotatably connected between the fixed shaft 3031 and the second main body 302. In these embodiments, by increasing the number of rotating shafts 3032 of the rotating shaft assembly 303, the rotating performance of the rotating shaft assembly 303 can be improved, the bending performance of the rotation shaft area 200c of the display screen 200 can be improved, and the rotation shaft area 200c of the display screen 200 can have a more natural bending state.

[0216] It can be understood that in some embodiments, the rotating shaft assembly 303 can also only include the fixed shaft 3031, and the opposite sides of the fixed shaft 3031 are rotatably connected with the first main body 301 and the second main body 302, respectively.

[0217] Please refer to Figure 6 , Figure 6An exploded structural schematic view of the first body 301 according to an embodiment of the present application is shown. It should be noted that the first body 301 and the second body 302 are identical or mirror images of each other in the embodiments of the present application, and the first body 301 is taken as an example to describe the structure of the first body 301 and the second body 302. In the embodiments, the first body 301 and the second body 302 each include a middle frame 304 and a back cover 305. The middle frame 304 included in the first body 301 is a first middle frame, and the back cover 305 included in the first body 301 is a first back cover. The middle frame 304 included in the second body 302 is a second middle frame, and the back cover 305 included in the second body 302 is a second back cover.

[0218] In the embodiments, the middle frame 304 includes a bezel 3041 and a middle plate 3042. The middle plate 3042 is located in an area surrounded by the bezel 3041 and is connected to the inner surface of the bezel 3041. The back cover 305 is fixed to the bezel 3041, and the back cover 305 is arranged opposite to the middle plate 3042. In some embodiments, the back cover 305 is spaced apart from the middle plate 3042, and the back cover 305, the middle plate 3042, and the bezel 3041 enclose a receiving space in which the battery, the main board, and other components of the foldable display terminal 1000 are received.

[0219] In the embodiments, the bezel 3041 includes a first section 3041A and a second section 3041B arranged opposite to each other, and a third section 3041C connected between the first section 3041A and the second section 3041B. One end of each of the first section 3041A and the second section 3041B is located at one end of the rotating shaft 3032 of the hinge assembly 303, and the other end is connected to the other end of the third section 3041C.

[0220] In the embodiments of the present application, the back cover 305 can be fixed to the bezel 3041 by various fixing methods such as buckling and gluing. It can be understood that in some other embodiments of the present application, the back cover 305 can also be an integral structure formed by integral molding with the bezel 3041.

[0221] Specifically, please refer to Figure 6In the embodiment, the first middle frame includes a first frame 3041 and a first middle plate 3042. The first middle plate is located in an area surrounded by the first frame and is connected to an inner surface of the first frame. A first back cover is fixed to the first middle frame and is arranged opposite to the first middle plate. There is a space between the first back cover and the first middle plate. The first back cover, the first middle plate and the first frame form a first receiving space. The second middle frame includes a second frame 3041 and a second middle plate 3042. The second middle plate is located in an area surrounded by the second frame and is connected to an inner surface of the second frame. A second back cover is fixed to the second middle frame and is arranged opposite to the second middle plate. There is a space between the second back cover and the second middle plate. The second back cover, the second middle plate and the second frame form a second receiving space. The battery, the main board and other components of the folding display terminal 1000 are received in the first receiving space and / or the second receiving space.

[0222] In the embodiment, the first fixed area 200a of the display screen 200 is fixed to a side of the first middle plate away from the first back cover, and the second fixed area 200b of the display screen 200 is fixed to a side of the second middle plate away from the second back cover. In the embodiment, there is a certain distance between the edge of the first fixed area 200a of the display screen 200 and the first frame, and there is a certain distance between the edge of the second fixed area 200b of the display screen 200 and the second frame. In this way, when the folding display terminal 1000 is impacted, the force during the impact can be transmitted to the display screen 200 through the first frame or the second frame, so that the display screen 200 is not damaged.

[0223] When the foldable display terminal 1000 of this application needs to be folded, the user applies force to the first main body 301 and the second main body 302, causing the end of the first main body 301 away from the pivot assembly 303 to move closer to the end of the second main body 302 away from the pivot assembly 303. The pivot shaft 3032 of the pivot assembly 303 rotates relative to the fixed shaft 303b, and the first main body 301 and the second main body 302 rotate relative to the pivot shaft 3032 connected to them. This causes the first fixed area 200a and the second fixed area 200b of the display screen 200 to fold about the pivot area 200c of the display screen 200. When the foldable display terminal 1000 needs to be unfolded, the user applies force to the first main body 301 and the second main body 302, causing the end of the first main body 301 away from the pivot assembly 303 to move closer to and further away from the end of the second main body 302 away from the pivot assembly 303. The pivot axis 3032 of the pivot assembly 303 rotates and unfolds relative to the fixed axis 303b. The first main body 301 and the second main body 302 rotate and unfold relative to the pivot axis 3032 connected to them, thereby causing the first fixed area 200a and the second fixed area 200b of the display screen 200 to unfold with the pivot area 200c of the display screen 200 as the axis.

[0224] Please refer to the following: Figure 4 and Figure 7 , Figure 7 for Figure 4 The diagram shows an enlarged view of a portion of the hinge trim 306 fixed to the hinge assembly 303. In this embodiment, the hinge assembly 303 further includes the hinge trim 306, which covers the side of the fixed shaft 3031 facing away from the display screen 200, preventing the hinge assembly 303 from being exposed and protecting it. Furthermore, the hinge trim 306 can be matched with the structure, color, etc., of the back cover 305 of the first main body 301 and the second main body 302 to give the foldable display terminal 1000 a better aesthetic appearance.

[0225] Please refer to the following: Figure 1 and Figure 4In the embodiment, the folding display terminal 1000 further comprises an edge protection assembly 1001. The edge protection assembly 1001 comprises an edge protection piece and an edge protection structure 100. The edge protection piece can cover the edges of the first fixed area 200a, the second fixed area 200b and the connecting area 2002 of the hinge area 200c of the display screen 200, and the edge protection structure 100 can cover the edges of the bending area 2001 of the hinge area 200c. Thus, the edges of the display screen 200 are protected by the edge protection piece and the edge protection structure 100, and the edges of the display screen 200 are prevented from being exposed, so as to improve the appearance effect of the folding display device 1000 and prevent the edges of the display screen 200 from being damaged due to collision.

[0226] For your reference Figure 1 and Figure 4 In the embodiment, the edge protection piece comprises a first edge protection piece 101 and a second edge protection piece 102. The first edge protection piece 101 is located on the side of the display screen 200 away from the first main body 301, and covers the edges of the first fixed area 200a and the first connecting area of the hinge area 200c of the display screen 200. The first edge protection piece 101 is fixedly connected with the first bezel of the first main body 301, and the first bezel of the first main body 301 and the first edge protection piece 101 can wrap the edges of the first fixed area 200a and the first connecting area of the display screen 200, so as to prevent the edges of the first fixed area 200a and the first connecting area of the display screen 200 from being exposed. Thus, the edges of the first fixed area 200a and the first connecting area of the display screen 200 can be prevented from being damaged due to collision or impact, and water, dust and the like can be prevented from entering the display screen 200 or the folding display terminal 1000 through the edges of the first fixed area 200a and the first connecting area of the display screen 200, so as to ensure better reliability of the display screen 200 and the folding display terminal 1000. The periphery of the first edge protection piece 101 can be fixedly connected with the second bezel in a snap-fit manner, an adhesive manner or other fixed connection manners, which is not specifically limited in the present application.

[0227] Similarly, the second edge protector 102 is located on the side of the display screen 200 facing away from the second main body 302, and the second edge protector 102 covers the edges of the second fixed area 200b and the second connecting area of ​​the display screen 200. Furthermore, the periphery of the second edge protector 102 is fixedly connected to the second frame. Through the second frame and the second edge protector 102, the edges of the second fixed area 200b and the second connecting area of ​​the display screen 200 are wrapped around, preventing the edges of the second fixed area 200b and the second connecting area of ​​the display screen 200 from being exposed. This prevents damage to the edges of the second fixed area 200b and the second connecting area of ​​the display screen 200 from collisions or impacts, and prevents water, dust, etc., from entering the display screen 200 or the foldable display terminal 1000 through the edges of the second fixed area 200b and the second connecting area of ​​the display screen 200, ensuring better reliability for the display screen 200 and the foldable display terminal 1000. The periphery of the second edge protection member 102 can be fixedly connected to the second frame by snap-fit, adhesive or other fixed connection methods, and no specific restrictions are imposed in this application.

[0228] Please refer to the following: Figure 1 and Figure 4 In this embodiment, there are two edge protection structures 100. The two edge protection structures 100 are located at opposite ends of the pivot assembly 303, and along the length of the bending area 2001 of the display screen 200 (i.e.,...). Figure 4 The edge protection structure 100 protects the edge of the bending area 2001 of the display screen 200, preventing the edge of the bending area 2001 of the display screen 200 from being exposed, thereby improving the appearance of the folding display terminal 1000. It also prevents the edge of the bending area 2001 of the display screen 200 from being damaged by impact, and prevents water, dust, etc. from penetrating into the display screen 200 or the folding display terminal 1000 through the edge of the bending area 2001 of the display screen 200, ensuring higher reliability for both the display screen 200 and the folding display terminal 1000.

[0229] For details, please refer to Figure 8 , Figure 9 and Figure 10 , Figure 8 The diagram shown is a structural schematic of the edge protection structure 100 according to the first embodiment of this application. Figure 9 for Figure 8 The diagram shows a cross-sectional view of the edge protection structure 100 cut along direction II. Figure 10 for Figure 8An exploded structural schematic diagram of the edge protection structure 100 is shown. In this embodiment, the edge protection structure 100 includes a hard piece 110, a connecting piece 120, and a soft rubber piece 130. The hard piece 110 is connected to the soft rubber piece 130 through the connecting piece 120.

[0230] In this embodiment, the strength of the hard piece 110 and the connecting piece 120 is greater than that of the soft rubber piece 130. The soft rubber piece 130 is an elastically deformable piece.

[0231] Figure 10 In this embodiment, the hard piece 110 and the connecting piece 120 can be metal pieces formed of a metal material, which have relatively high strength. Specifically, the metal material forming the hard piece 110 and the connecting piece 120 can be various types of metal materials or alloy materials, such as stainless steel, cast iron, aluminum, etc. It can be understood that in other embodiments of the present application, the hard piece 110 and the connecting piece 120 can also be formed of other types of materials. For example, in some embodiments, the hard piece 110 or the connecting piece 120 can be a fine ceramic piece formed of a fine ceramic material.

[0232] In this embodiment, the hard piece 110 can be obtained by metal injection molding (MIM). In this embodiment, the hard piece 110 obtained by metal injection molding has relatively high dimensional accuracy, which facilitates the cooperation of the edge protection structure 100 with other structures of the foldable display terminal 1000. In addition, the hard piece 110 obtained by metal injection molding has uniform microstructure and high relative density at each position, thereby having relatively high strength, so that better protection effect on the edge of the display screen 200 can be achieved. In addition, the hard piece 110 has good surface finish, so that the foldable display terminal 1000 can have a better appearance effect. It can be understood that in other embodiments of the present application, the hard piece 110 can also be formed by other processes, such as computer numerical control (CNC) machining, die casting, etc.

[0233] Figure 10In the illustrated embodiment, the soft rubber part 130 is an elastically deformable part. The soft rubber part 130 has relatively low strength and can be bent and deformed. In some embodiments of this application, the soft rubber part 130 is made of an elastically deformable soft rubber material. Specifically, the soft rubber material forming the soft rubber part 130 can be silicone, thermoplastic elastomer (TPE), thermoplastic polyurethanes (TPU), polyvinyl chloride (PVC) soft rubber, or rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene-butadiene rubber, propylene rubber, etc.). It is understood that the soft rubber part 130 of this application can also be formed of other elastically deformable materials, which will not be listed here.

[0234] In some embodiments of this application, the surfaces of both the rigid component 110 and the flexible component 130 may be coated with a plating layer to further improve the appearance of the edge protection structure 100. For example, in some embodiments, the plating layer on the surface of the rigid component 110 has the same color as the back cover of the foldable display terminal 1000, thereby making the appearance color of the foldable display terminal 1000 uniform and thus having a better appearance. In some embodiments, the plating layer can also block external water, oxygen, and other substances from corroding the rigid component 110, thereby improving the quality of the foldable display terminal 1000.

[0235] In this application, the coating may be formed by vapor deposition or by vapor deposition, and no specific limitation is made on the formation method of the coating.

[0236] Figure 10 In the illustrated embodiment, the rigid component 110 includes a connecting end 111 and a fixed end 112 connected to the connecting end 111. Please refer to [link / reference]. Figure 11 , Figure 12 and Figure 13 , Figure 11 As shown Figure 10 The schematic diagram shows the portion of the edge protection structure 100 where the rigid component 110 is fixed to the rotating shaft assembly 303. Figure 12 As shown Figure 10 A partial exploded view of the rigid component 110 and the pivot assembly 303 of the edge protection structure 100 shown. Figure 13 As shown Figure 11The schematic diagram of the cross section at the middle position II-II. In this embodiment, the fixed end 112 of the hard piece 110 is fixed on the fixed shaft 3031 of the rotating shaft assembly 303, so as to fix the edge protection structure 100 and the rotating shaft assembly 303. In this embodiment, the fixed shaft 3031 is provided with a slot 307 at both ends, and the fixed end 112 of the hard piece 110 is inserted into the slot 307 and fixed. In this embodiment, the fixed end 112 of the hard piece 110 is inserted into the slot 307 and fixed with the slot wall of the slot 307 by adhesive. It can be understood that in other embodiments of the present application, the hard piece 110 can also be fixed with the fixed shaft 3031 by other ways. For example, the hard piece 110 can be fixed with the fixed shaft 3031 by various ways such as clamping, screwing, etc., which will not be described here.

[0237] Please refer to Figure 10 In some embodiments of the present application, the hard piece 110 is a plate structure. The connecting end 111 of the hard piece 110 includes oppositely arranged first and second surfaces 1111 and 1112, and the first surface 1111 is closer to the outside of the folding display terminal 1000 than the second surface 1112. The fixed end 112 of the hard piece 110 includes oppositely arranged third and fourth surfaces 1113 and 1114, and the third surface 1113 is closer to the outside of the folding display terminal 1000 than the fourth surface 1114. In this embodiment, the connecting end 111 and the fixed end 112 of the hard piece 110 are connected to form a stepped structure, i.e., the first surface 1111 of the connecting end 111 and the third surface 1113 of the fixed end 112 are arranged non-coplanarly, and the first surface 1111 of the connecting end 111 is closer to the outside of the folding display terminal 1000 than the third surface 1113 of the fixed end 112, and the first surface 1111 of the connecting end 111 and the third surface 1113 of the fixed end 112 are connected by a fifth surface 1115.

[0238] Please refer to Figure 11 In this embodiment, when the fixed end 112 of the hard piece 110 is inserted into the slot 307 of the fixed shaft 3031, the fifth surface 1115 of the hard piece 110 is in contact with the surface of the fixed shaft 3031, so as to ensure that the fixed end 112 of the hard piece 110 can be more stable when inserted into the fixed shaft 3031. In this embodiment, when the hard piece 110 is fixed with the fixed shaft 3031, the first surface 1111 of the connecting end 111 of the hard piece 110 is coplanar with one end surface 3033 of the fixed shaft 3031, so as to make the appearance of the folding display terminal 1000 more flat and have a better appearance effect.

[0239] Please refer to Figure 11 and Figure 13In this embodiment, the width of the fixed end 112 can be smaller than the width of the connecting end 111. When the rigid component 110 is fixed to the fixed shaft 3031, the width direction of the fixed end 112 of the rigid component 110 is the same as the width direction of the connecting end 111 and the width direction of the fixed shaft 3031. Figure 13 In the X direction. When the fixed end 112 of the rigid component 110 is inserted into the slot 307 of the fixed shaft 3031, the portion of the connecting end 111 that extends beyond the fixed end 112 in the width direction abuts against the surface of the fixed shaft 3031, which can further ensure that the fixed end 112 of the rigid component 110 is more stable when inserted into the slot 307 of the fixed shaft 3031, and is less likely to shake and fall off.

[0240] Please refer to them again. Figure 9 and Figure 10 In this embodiment, the flexible rubber component 130 includes a protective portion 131. The protective portion 131 includes a first surface 1311 and a second surface 1312 disposed opposite to each other, and a third surface 1313 and a fourth surface 1314 connected between the first surface 1311 and the second surface 1312. The third surface 1313 and the fourth surface 1314 are disposed opposite to each other. When the edge protection structure 100 is fixed to the pivot assembly 303, the third surface 1313 of the protective portion 131 faces the display screen 200. Figure 10 In the embodiment shown, the third surface 1313 is a plane.

[0241] Please see Figure 14 , Figure 14 This is a schematic diagram of the edge protection structure 100 according to the second embodiment of this application. The edge protection structure 100 in this embodiment is similar to... Figure 10 The edge protection structure 100 shown is basically the same, except that: Figure 14In the edge protection structure 100 of the illustrated embodiment, the third surface 1313 is an arc surface concave towards the fourth surface 1314. In this embodiment, when the pivot area 200c of the display screen 200 is bent, the protection part 131 of the soft gel piece 130 will bend along with the pivot area 200c of the display screen 200. When the protection part 131 is bent, the two ends of the protection part 131 will move closer to each other. The fourth surface 1314 is the inner surface of the protection part 131 when the protection part 131 is bent. After the protection part 131 is bent multiple times along with the display screen 200, the protection part 131 is prone to plastic deformation, so that the two ends of the protection part 131 will be raised away from the display screen 200. In this embodiment, by designing the third surface 1313 of the protection part 131 as an arc surface slightly concave towards the fourth surface 1314, even if the protection part 131 has an initial deformation towards the display screen 200, it can partially neutralize the deformation of the protection part 131 towards the fourth surface 1314 after multiple bending, reduce the risk of the two ends of the protection part 131 being raised after multiple bending, and prolong the service life of the edge protection structure 100.

[0242] It should be noted that, Figure 14 In the illustrated embodiment, the third surface 1313 has a small bending radius, so that when the protection part 131 covers the edge of the pivot area 200c of the display screen 200, the third surface 1313 of the protection part 131 can be substantially free of gaps with the display screen 200, thereby reducing the invasion of water, dust, etc. through the gap between the third surface 1313 and the display screen 200 into the display screen 200 or the folding display terminal 1000, and at the same time, the two ends of the third surface 1313 bent towards the display screen 200 have less pressure on the display screen 200, thereby avoiding damage to the display screen 200.

[0243] Figure 14 In the illustrated embodiment, the first surface 1311 and the second surface 1312 are both planar surfaces, the fourth surface 1314 is an arc surface, and the bending radius of the fourth surface 1314 is greater than that of the third surface 1313, so that the edge protection structure 100 can have a better appearance effect. It should be understood that in this application, the forms of the first surface 1311, the second surface 1312, the third surface 1313 and the fourth surface 1314 of the protection part 131 can also be changed, i.e., the forms of the first surface 1311, the second surface 1312, the third surface 1313 and the fourth surface 1314 of the protection part 131 in this application are not specifically limited. For example, in some embodiments, the first surface 1311 and the second surface 1312 of the protection part 131 can also be arc surfaces, and the third surface 1313 and the fourth surface 1314 can be planar surfaces.

[0244] Please refer back to Figure 9In some embodiments of the present application, the protection part 131 is further provided with a groove 1315 recessed from the third surface 1313 to the fourth surface 1314. By providing the groove 1315, the outer surface shape of the protection part 131 can be ensured unchanged, so that the protection part 131 can be more easily deformed to ensure that the folding display terminal 1000 has a good appearance effect, and the protection part 131 can better follow the display screen 200 to bend and deform without easily damaging the display screen 200 by a large force.

[0245] Please refer back to Figure 8 、 Figure 9 and Figure 10 In the embodiments of the present application, the hard piece 110 is located on one side of the first surface 1311 of the protection part 131. Figure 10 In the embodiments shown in the drawings, the first surface 1311 of the protection part 131 is recessed in the direction of the second surface 1312 with a groove 1316, and the connecting end 111 of the hard piece 110 is located in the groove 1316 of the protection part 131. The connecting end 111 of the hard piece 110 can be embedded in the groove 1316 of the protection part 131, and the groove wall of the groove 1316 can block the shaking of the hard piece 110 relative to the soft rubber piece 130 to ensure the stability of the connection between the hard piece 110 and the soft rubber piece 130. It can be understood that in other embodiments of the present application, the protection part 131 can also not have the groove 1316, the hard piece 110 is located on one side of the first surface 1311 of the protection part 131, and the second surface 1312 of the hard piece 110 is in contact with the first surface 1311 of the protection part 131.

[0246] Figure 10 In the embodiments shown in the drawings, the groove 1316 extends to the fourth surface 1314 of the protection part 131, so that one side of the fourth surface 1314 facing the first surface 1311 forms a gap. It can be understood that in some other embodiments of the present application, the groove 1316 can also not extend to the fourth surface 1314 of the protection part 131, that is, there can be a certain spacing between the groove 1316 and the fourth surface 1314. For example, please refer to Figure 15 , Figure 15 The structure shown in the drawings is a structure schematic view of the edge protection structure 100 of the third embodiment of the present application. The edge protection structure 100 in the embodiments of the present application is basically the same as the edge protection structure 100 shown in Figure 10 , the difference is that in the present embodiment, there is a certain spacing a between the groove 1316 and the fourth surface 1314, and the hard piece 110 is embedded in the groove 1316.

[0247] Please refer back to Figure 10In some embodiments of the present application, the soft rubber piece 130 further comprises two fixing parts 132 respectively connected to two ends of the protection part 131, and part of the fixing part 132 is connected to the third surface 1313 of the protection part 131. Specifically, the fixing part 132 comprises oppositely arranged first surface 1321 and second surface 1322, and the third surface 1323 connected between the first surface 1321 and the second surface 1322. In this embodiment, part of the third surface 1313 of the fixing part 132 is connected to the third surface 1313 of the protection part 131.

[0248] In this embodiment, the fixing part 132 and the protection part 131 can be an integral structure obtained by injection molding. In this embodiment, since the fixing part 132 and the protection part 131 are an integral structure, the combination between the fixing part 132 and the protection part 131 can be more firm, avoiding separation between the fixing part 132 and the protection part 131 in the folding process of the folding display terminal 1000, thereby ensuring the quality of the folding display terminal 1000. It can be understood that in some other embodiments of the present application, the fixing part 132 and the protection part 131 can also be fixed by other ways. For example, in some embodiments, the fixing part 132 and the protection part 131 can also be fixed by the way of gluing.

[0249] It should be noted that in some embodiments of the present application, the soft rubber piece 130 can only have the protection part 131 without the fixing part 132.

[0250] In some embodiments, the fixing part 132 further embeds a hard plate 133. The strength of the hard plate 133 is greater than that of the fixing part 132, which can enhance the strength of the fixing part 132 through the hard plate 133, avoiding deformation of the fixing part 132. In some embodiments of the present application, the hard plate 133 can be made of metal material or other materials.

[0251] In the embodiments of the present application, the connecting piece 120 is used to connect the hard piece 110 and the soft rubber piece 130. The connecting piece 120 is made of non-elastic deformation material and has a certain strength, so as to ensure that it can play a good connecting effect. In this embodiment, the connecting piece 120 can be made of metal material, metal alloy material or rigid material such as plastic material, ceramic material with high strength.

[0252] Please refer to Figure 9 and Figure 10 In this embodiment, the connecting piece 120 comprises intersecting first part 121 and second part 122, the first part 121 is connected to the protection part 131 of the soft rubber piece 130, and the second part 122 is connected to the hard piece 110, thereby realizing the connection between the hard piece 110 and the soft rubber piece 130.

[0253] Specifically, in the embodiment, the first part 121 of the connecting member 120 is perpendicular to the second part 122. The first part 121 of the connecting member 120 is embedded in the protection part 131 of the soft glue member 130. In the embodiment, the first part 121 of the connecting member 120 and the soft glue member 130 are an integrated structure formed by an integral molding process. It should be noted that the components A and B in the present application are an integrated structure formed by an integral molding process, which means that the components A and B are connected together during the forming process of the components A and / or B, and the components A and B do not need to be connected together by reprocessing (such as bonding, welding, buckle connection, screw connection). In the embodiment, the first part 121 of the connecting member 120 and the soft glue member 130 are an integrated structure formed by injection molding. Specifically, the formed connecting member 120 is placed in a mold, and then the molten soft glue material is filled into the mold. After the molten soft glue material cools and solidifies, the soft glue member 130 of the embodiment is formed, and the first part 121 of the connecting member 120 is embedded in the protection part 131 of the soft glue member 130 and forms an integrated structure with the protection part 131 of the soft glue member 130. In the embodiment, by forming the soft glue member 130 and the first part 121 of the connecting member 120 into an integrated structure, the connection between the soft glue member 130 and the connecting member 120 is stable, the quality of the edge protection structure 100 is guaranteed, and the quality of the foldable display terminal 1000 is improved.

[0254] Referring to Figure 10 In some embodiments, the first part 121 of the connecting member 120 is further provided with a positioning hole 1211. The positioning hole 1211 can facilitate the positioning of the connecting member 120 in the mold. Moreover, the first part 121 of the connecting member 120 and the protection part 131 of the soft glue member 130 form an integrated structure, and the positioning hole 1211 is also filled with the soft glue material forming the protection part 131. That is, the positioning hole 1211 can increase the contact area between the first part 121 of the connecting member 120 and the protection part 131 of the soft glue member 130, and further improve the stability of the connection between the first part 121 of the connecting member 120 and the protection part 131 of the soft glue member 130.

[0255] It can be understood that in other embodiments of the present application, the soft glue member 130 and the first part 121 of the connecting member 120 can also be connected by a bonding process. For example, in some embodiments, a groove recessed from the first surface 1311 to the second surface 1312 is provided on the protection part 131 of the soft glue member 130, and the first part 121 of the connecting member 120 is inserted into the groove, and the first part 121 of the connecting member 120 and the groove wall are fixed by adhesive.

[0256] Referring to Figure 16 , Figure 16 as shown alongFigure 8 In the embodiment, the first part 121 of the connecting member 120 is connected to the middle position of the protection part 131 of the soft rubber member 130. Since the connecting member 120 is a structural member with certain strength, the position where the protection part 131 is connected to the first part 121 of the connecting member 120 will not be elastically deformed, but other positions of the protection part 131 can still be elastically deformed. When the display screen 200 is folded, the two ends of the protection part 131 can be folded about the position where the protection part 131 is connected to the first part 121 of the connecting member 120.

[0257] In the embodiment, the second part 122 of the connecting member 120 is connected to the connecting end 111 of the hard member 110, so that the hard member 110 and the soft rubber member 130 are connected through the connecting member 120. Specifically, in the embodiment, the connecting member 120 is in contact with the second surface 1112 of the hard member 110, and the connecting member 120 is fixedly connected to the second surface 1112 of the hard member 110 through adhesive, so that the hard member 110 and the connecting member 120 are fixedly connected.

[0258] Please refer to Figure 10 In some embodiments of the present application, the second surface 1112 of the connecting end 111 of the hard member 110 is concavely provided with a groove 1116 towards the first surface 1111, and the second part 122 of the connecting member 120 can be embedded in the groove 1116, and the second part 122 of the connecting member 120 is adhered to the inner wall of the groove 1116. In the embodiment, by providing the groove 1116 in the connecting end 111 of the hard member 110, the adhesive used to glue the hard member 110 and the connecting member 120 can be accommodated in the groove 1116, and is not easy to flow to other positions which are not required to be connected to the second part 122 of the connecting member 120, so that the adhesive can effectively adhere and fix the second part 122 of the connecting member 120 to the inner wall of the groove 1116. In addition, since the groove 1116 is provided, the groove wall of the groove 1116 can limit the shaking of the second part 122 of the connecting member 120 in all directions in the groove 1116, so as to reduce the problem that the second part 122 and the hard member 110 can be separated when the folding display terminal 1000 is impacted.

[0259] It can be understood that in some other embodiments of the present application, the connecting mode of the second part 122 of the connecting member 120 and the connecting end 111 of the hard member 110 can also be screw connection, soldering or buckle connection, and the present application does not make specific limitation thereto.

[0260] Please refer to Figure 17 , Figure 18 andFigure 19 , Figure 17 FIG. 6 is an enlarged schematic view of the position I shown in FIG. 5; Figure 1 FIG. 7 is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in FIG. 5; Figure 18 FIG. 8 is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in FIG. 6; Figure 8 FIG. 9 is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in FIG. 7; Figure 19 FIG. 10 is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in FIG. 8; Figure 17 FIG. 11 is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in FIG. 9;

[0261] In addition, since the edge of the folding area of the display screen 200 is wrapped by the hard material 110 and the soft rubber 130, when the folding display terminal 1000 is subjected to a collision, the edge position of the folding area 2001 of the display screen 200 is not easily damaged by the collision due to the protection of the edge protection structure 100, further improving the reliability of the folding display terminal 1000. In some embodiments of the present application, there is a certain gap between the edge of the folding area 2001 of the display screen 200 and the hard material 110. When the folding display terminal 1000 is subjected to a collision, the collision force acts on the hard material 110 and is not easily transmitted to the display screen 200 to damage the display screen 200, further improving the reliability of the folding display terminal 1000.

[0262] In this embodiment, the rigid component 110 of the edge protection structure 100 is made of a high-strength material (such as metal), which can achieve a good anti-collision effect, thereby providing good protection for the flexible screen 200. Meanwhile, in this embodiment, the soft component 130 of the edge protection structure 100 is made of a soft rubber material with elastic deformation properties, and the protective portion 131 of the soft component 130 covers the edge of the bending area 2001 of the display screen 200. When the foldable display terminal 1000 is folded, the ends of the first main body 301 and the second main body 302 of the foldable display terminal 1000 that are away from the hinge assembly 303 move closer to each other, thereby causing the display screen 200, which is fixed to the first main body 301 and the second main body 302, to fold. In this embodiment, when the display screen 200 is folded, the protective portion 131 covering the edge of the hinge area 200c of the display screen 200 can bend and deform along with the display screen 200. In this embodiment, since the soft rubber component 130 is made of elastically deformable soft rubber material, it has virtually no impact on the bending state of the display screen 200. Instead, it can change shape accordingly with the bending state of the display screen 200. Therefore, when the display screen 200 of this embodiment is fully folded, the first fixing area 200a and the second fixing area 200b of the display screen 200 can fit together, and the pivot area 200c of the display screen 200 can naturally bend into a teardrop shape. In other words, in this embodiment, by providing an edge protection structure 100 in the foldable display terminal 1000, the edge of the bending area 100c of the display screen 100 of the foldable display terminal 1000 can be protected, and the appearance of the foldable display terminal 1000 can be improved without affecting the folding of the display screen 100 or the reliability of the display screen 200. Please refer to... Figure 20- Figure 22 , Figure 20 The image shown is a foldable display terminal 1000 according to one embodiment of this application. Figure 1 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 in the flattened state shown. Figure 21 The image shown is a foldable display terminal 1000 according to one embodiment of this application. Figure 2 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 when folded to the middle state. Figure 22 The image shown is a foldable display terminal 1000 according to one embodiment of this application. Figure 3 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 when it is folded to the fully closed state.

[0263] Please refer to the previous document. Figure 18 and Figure 19In the embodiments of the present application, the two fixing portions 132 of the soft rubber piece 130 are respectively a first fixing portion and a second fixing portion. The first fixing portion is arranged between the first rotating shaft of the rotating shaft assembly 303 and the first frame, and is located on the side of the first edge protection piece 101 facing the display screen 200. The second fixing portion is arranged between the second rotating shaft of the rotating shaft assembly 303 and the second frame of the second main body 302, and is located on the side of the second edge protection piece 102 facing the display screen 200. In the embodiments of the present application, since the two fixing portions 132 (i.e. the first fixing portion and the second fixing portion) of the soft rubber piece 130 are pressed by the first edge protection piece 101 and the second edge protection piece 102 respectively, the problem that the two ends of the protection portion 131 are raised after the protection portion 131 is folded and unfolded with the display screen 200 for multiple times can be avoided.

[0264] Referring to Figure 18 In some embodiments of the present application, there is a gap L between the first rotating shaft and the first frame of the first main body 301, and between the second rotating shaft and the second frame of the second main body 302. The gap L is greater than the thickness d of the fixing portion 132, so as to facilitate the assembly of the fixing portion 132. However, the gap L cannot be too large, so as to limit the fixing portion 132 in a certain space, avoid the deformation of the fixing portion 132 during the folding or unfolding of the folding display terminal 1000, and ensure the appearance effect of the folding display terminal 1000 and the protection effect of the edge of the rotating shaft area 200c of the display screen 200. In some embodiments of the present application, the gap L is less than twice the thickness d of the fixing portion 132.

[0265] Referring to Figure 23 , Figure 23 Fig. 4 is a sectional view of an edge protection structure 100 according to a fourth embodiment of the present application. The edge protection structure 100 of the fourth embodiment of the present application has basically the same structure as the edge protection structure 100 shown in Fig. 1, and the difference between the edge protection structure 100 of the fourth embodiment of the present application and the edge protection structure 100 shown in Fig. 1 is that the edge protection structure 100 of the fourth embodiment of the present application further comprises a third edge protection piece 103. Figure 10 Fig. 4 is a sectional view of an edge protection structure 100 according to a fourth embodiment of the present application. The edge protection structure 100 of the fourth embodiment of the present application has basically the same structure as the edge protection structure 100 shown in Fig. 1, and the difference between the edge protection structure 100 of the fourth embodiment of the present application and the edge protection structure 100 shown in Fig. 1 is that the edge protection structure 100 of the fourth embodiment of the present application further comprises a third edge protection piece 103. Figure 10The difference of the edge protection structure 100 shown is that in the embodiment, the second part 122 of the connecting piece 120 and the connecting end 111 of the hard piece 110 are an integral structure formed by integral molding, without the need to fix the molded hard piece 110 or connecting piece 120 together by adhesive, welding, screw, buckle or other fixing methods, so that the hard piece 110 and the connecting piece 120 can be connected more stably. In the embodiment, the soft glue piece 130 and the first part 121 of the connecting piece 120 are also an integral structure formed by integral molding, so that the soft glue piece 130 and the hard piece 110 are connected more stably through the connecting piece 120. Specifically, in the embodiment, the connecting piece 120 and the hard piece 110 are made of the same kind of metal material. The hard piece 110 and the connecting piece 120 are integrally molded by metal injection molding (MIM), so that the second part 122 of the connecting piece 120 and the connecting end 111 of the hard piece 110 become an integral structure, realizing the connection of the second part 122 of the connecting piece 120 and the connecting end 111 of the hard piece 110. At this time, the first part 121 of the connecting piece 120 protrudes from the surface of the hard piece 110. Then the connecting piece 120 and the hard piece 110 in an integral structure are put into a mold, and then the molten soft glue material is filled into the mold. After the molten soft glue material is cooled and solidified, the soft glue piece 130 of the embodiment is formed, and the first part 121 of the connecting piece 120 is embedded in the soft glue piece 130, and the soft glue piece 130 and the first part 121 of the connecting piece 120 form an integral structure. It should be noted that in the embodiment, since the connecting piece 120 and the hard piece 110 are structures of the same material, when the second part 122 of the connecting piece 120 and the hard piece 110 are integrally molded, an integral structure is formed. At this time, the second part 122 of the connecting piece 120 and the hard piece 110 are artificially divided structures for easy understanding, and there is no actual division interface. It can be understood that in other embodiments of the application, the integral structure of the connecting piece 120 and the hard piece 110 can also be formed by numerical control machining, die casting or other methods.

[0266] Please refer to Figure 24 and Figure 25 , Figure 24 The structure schematic diagram of the edge protection structure 100 of the fifth embodiment of the application is shown in Figure 25 The edge protection structure 100 shown in Figure 24 replaces the edge protection structure 100 in Figure 1 when the edge protection structure 100 is installed on the folding display terminal 1000. When the folding display terminal 1000 is cut along the position IV-IV shown in Figure 17 , the partial cross-sectional schematic diagram is shown. The edge protection structure 100 of the embodiment and Figure 8The edge protection structure 100 shown in the figure is basically the same as the edge protection structure 100 of the embodiment, and the difference between the edge protection structure 100 shown in the figure and the edge protection structure 100 of the embodiment is that the soft rubber part 130 of the edge protection structure 100 shown in the figure further comprises two extension parts 134, and the two extension parts 134 are respectively connected to the two ends of the protection part 131. When the edge protection structure 100 of the embodiment is applied to the folding display terminal 1000, one extension part 134 of the soft rubber part 130 is pressed against the side of the first edge protection part 101 facing the display screen 200, and the other extension part 134 is pressed against the side of the second edge protection part 102 facing the display screen 200, so that the shape of the protection part 131 can be further maintained, and the problem that the two ends of the protection part 131 are raised after the protection part 131 is bent multiple times along with the display screen 200 can be avoided. Figure 8 The edge protection structure 100 shown in the figure is basically the same as the edge protection structure 100 of the embodiment, and the difference between the edge protection structure 100 shown in the figure and the edge protection structure 100 of the embodiment is that the soft rubber part 130 of the edge protection structure 100 shown in the figure further comprises two extension parts 134, and the two extension parts 134 are respectively connected to the two ends of the protection part 131. When the edge protection structure 100 of the embodiment is applied to the folding display terminal 1000, one extension part 134 of the soft rubber part 130 is pressed against the side of the first edge protection part 101 facing the display screen 200, and the other extension part 134 is pressed against the side of the second edge protection part 102 facing the display screen 200, so that the shape of the protection part 131 can be further maintained, and the problem that the two ends of the protection part 131 are raised after the protection part 131 is bent multiple times along with the display screen 200 can be avoided.

[0267] In the embodiment, the width of the extension part 134 is basically the same as the width of the protection part 131. The width direction of the extension part 134 and the width direction of the protection part 131 are both the direction from the first surface 1311 to the second surface 1312 of the protection part 131. In the embodiment, since the width of the extension part 134 is basically the same as the width of the protection part 131, when the extension part 134 is pressed against the side of the first edge protection part 101 or the second edge protection part 102 facing the display screen 200, each position of the protection part 131 in the width direction is stretched by the extension part 134 connected to the two ends of the protection part 131, so that each position of the two ends of the protection part 131 is not easy to be raised.

[0268] The extension part 134 comprises a contact surface 1341 and a fixed surface 1342. The contact surface 1341 faces the display screen 200 and is in contact with the display screen 200. The fixed surface 1342 is opposite to the contact surface 1341 and is in contact with the first edge protection part 101 or the second edge protection part 102. In the embodiment, the contact surface 1341 is smoothly connected to the third surface 1313 of the protection part 131, so that the position where the contact surface 1341 is connected to the third surface 1313 does not have a large angle change and does not have a protrusion, so that the protrusion generated by the contact between the contact surface 1341 and the third surface 1313 does not generate a large pressure on the display screen 200, and the display screen 200 is not damaged by the pressure of the soft rubber part 30.

[0269] Please refer to Figure 26 and Figure 27 , Figure 26 The structure of the edge protection structure 100 of the sixth embodiment of the application is shown in the figure, Figure 27 The edge protection structure 100 shown in the figure is basically the same as the edge protection structure 100 of the embodiment, and the difference between the edge protection structure 100 shown in the figure and the edge protection structure 100 of the embodiment is that the soft rubber part 130 of the edge protection structure 100 shown in the figure further comprises two extension parts 134, and the two extension parts 134 are respectively connected to the two ends of the protection part 131. When the edge protection structure 100 of the embodiment is applied to the folding display terminal 1000, one extension part 134 of the soft rubber part 130 is pressed against the side of the first edge protection part 101 facing the display screen 200, and the other extension part 134 is pressed against the side of the second edge protection part 102 facing the display screen 200, so that the shape of the protection part 131 can be further maintained, and the problem that the two ends of the protection part 131 are raised after the protection part 131 is bent multiple times along with the display screen 200 can be avoided. Figure 26 The edge protection structure 100 shown in the figure is basically the same as the edge protection structure 100 of the embodiment, and the difference between the edge protection structure 100 shown in the figure and the edge protection structure 100 of the embodiment is that the soft rubber part 130 of the edge protection structure 100 shown in the figure further comprises two extension parts 134, and the two extension parts 134 are respectively connected to the two ends of the protection part 131. When the edge protection structure 100 of the embodiment is applied to the folding display terminal 1000, one extension part 134 of the soft rubber part 130 is pressed against the side of the first edge protection part 101 facing the display screen 200, and the other extension part 134 is pressed against the side of the second edge protection part 102 facing the display screen 200, so that the shape of the protection part 131 can be further maintained, and the problem that the two ends of the protection part 131 are raised after the protection part 131 is bent multiple times along with the display screen 200 can be avoided. Figure 1 When the edge protection structure 100 shown in the figure is installed on the folding display terminal 1000 instead of the edge protection structure 100 in the figure, the folding display terminal 1000 is folded along Figure 17The diagram shows a partial cross-section when position IV-IV is cut open. The edge protection structure 100 of this embodiment and... Figure 24 The edge protection structure 100 shown is basically the same as that in this embodiment. Figure 24 The difference in the edge protection structure 100 shown is that the fixing surface 341 of the extension 134 is smoothly connected to the fourth surface 1314 of the protection part 131, avoiding obvious step changes or angle changes in the connection position between the fixing surface 341 of the extension 134 and the fourth surface 1314 of the protection part 131. Therefore, when the edge protection structure 100 is installed on the hinge assembly 303, it does not need to have high precision to ensure that the outer surface of the folding display terminal 1000 has a good appearance. It avoids the problem of appearance asymmetry or affecting the installation of the first edge protection member 101 or the second edge protection member 102 when the fixing surface 341 of the extension 134 and the fourth surface 1314 of the protection part 131 are connected by obvious step changes or angle changes.

[0270] In this application, the edge protection structure 100 can also be other structures. Please refer to 28. Figure 29 and Figure 30 , Figure 28 The diagram shown is a structural schematic of the edge protection structure 100 according to the seventh embodiment of this application. Figure 29 for Figure 28 The diagram shows the exploded structure of the edge protection structure 100. Figure 30 As shown Figure 28 The diagram shows a cross-sectional view of the edge protection structure 100 cut along position AA. In this embodiment, the edge protection structure 100 includes a rigid component 210 and two pivot components 220. One end of each pivot component 220 is rotatably connected to the rigid component 210, and the other end is a free end. The pivot components 220 can rotate about the position where they are connected to the rigid component 210. In this embodiment, the rigid component 210 includes a connecting end 211 and a fixed end 212 connected to the connecting end 211. The fixed end 212 is used to fix the rigid component 210, and the connecting end 211 is used to connect the pivot components 220. In this embodiment, the fixed end 212 and the connecting end 211 are an integral structure. The fixed end 212 and the connecting end 211 are two parts defined for the convenience of describing the structure of the rigid component 210.

[0271] Please see Figure 31 , Figure 32 and Figure 33 , Figure 31 As shown Figure 28 This is a partial structural diagram showing the rigid component 210 of the edge protection structure 100 being fixed to the rotating shaft assembly 303. Figure 32As shown Figure 28 An exploded structural schematic diagram of the hard piece 210 of the edge protection structure 100 and part of the rotating shaft assembly 303, Figure 33 As shown Figure 31 A cross-sectional schematic diagram of the edge protection structure 100 along the position B-B. The fixed end 212 of the hard piece 210 is fixed on the fixed shaft 3031 of the rotating shaft assembly 303, so as to realize the fixation of the edge protection structure 100 and the rotating shaft assembly 303. In the embodiment, the two ends of the fixed shaft 3031 are also provided with the insertion slot 307, and the fixed end 212 of the hard piece 210 is inserted into the insertion slot 307 of the fixed shaft 3031 and fixed, so as to realize the fixation between the hard piece 210 and the fixed shaft 3031. In the embodiment, the fixed end 212 of the hard piece 210 is inserted into the insertion slot 307 and fixed with the slot wall of the insertion slot 307 through the adhesive. It can be understood that in other embodiments of the present application, the hard piece 210 can also be fixed with the fixed shaft 3031 through other ways. For example, the fixation of the hard piece 210 and the fixed shaft 3031 can be realized through various ways such as clamping, screw fixation, etc., which will not be described herein.

[0272] Please refer to Figure 30 the structure of the hard piece 210 in the embodiment is basically the same as Figure 10 the structure of the hard piece 110 in the embodiment. In the embodiment, the hard piece 210 is in a plate structure. The connecting end 211 of the hard piece 210 includes the oppositely arranged first surface 2111 and the second surface 2112, and the first surface 2111 is closer to the outside of the folding display terminal 1000 than the second surface 2112. The fixed end 212 of the hard piece 210 includes the oppositely arranged third surface 2113 and the fourth surface 2114, and the third surface 2113 is closer to the outside of the folding display terminal 1000 than the fourth surface 2114. In the embodiment, the connecting end 211 and the fixed end 212 of the hard piece 210 are connected to form a stepped structure, that is, the first surface 2111 of the connecting end 211 and the third surface 2113 of the fixed end 212 are arranged in a non-coplanar manner, and the first surface 2111 of the connecting end 211 is closer to the outside of the folding display terminal 1000 than the third surface 2113 of the fixed end 212, and the first surface 2111 of the connecting end 211 and the third surface 2113 of the fixed end 212 are connected through the fifth surface 2115. Please refer to Figure 31 and Figure 33 In the embodiment, when the fixed end 212 of the hard piece 210 is inserted into the insertion slot 307 of the fixed shaft 3031, the fifth surface 2115 of the hard piece 210 is in contact with the surface of the fixed shaft 3031, so as to ensure that the fixed end 212 of the hard piece 210 can be more stable when inserted into the fixed shaft 3031. And, please refer to Figure 31 and Figure 32In some embodiments, when the rigid component 210 is fixed to the fixed shaft 3031, the first surface 2111 of the connecting end 211 of the rigid component 210 is coplanar with one end face 3033 of the fixed shaft 3031, so that the appearance of the folding display terminal 1000 can be relatively flat and have a better appearance effect.

[0273] Please see Figure 33 In this embodiment, the width of the fixed end 212 is smaller than the width of the connecting end 211. When the rigid component 210 is fixed to the fixed shaft 3031, the width direction of the fixed end 212 of the rigid component 210 is the same as the width direction of the connecting end 211 and the width direction of the fixed shaft 3031. Figure 33 In the X direction. When the fixed end 212 of the rigid component 210 is inserted into the slot 307 of the fixed shaft 3031, the portion of the connecting end 211 that extends beyond the fixed end 212 in the width direction abuts against the surface of the fixed shaft 3031. This further ensures that the fixed end 212 of the rigid component 210 is more stable when inserted into the slot 307 of the fixed shaft 3031, and is less prone to shaking and falling off.

[0274] Please refer to the previous document. Figure 29 In this embodiment, two connecting posts 213 are protruding from the second surface 2112 of the rigid component 210 and arranged side by side with a distance between them. The arrangement direction of the two connecting posts 213 is the same as the width direction of the rigid component 210, as shown in the figure. Figure 29 The X-axis direction is shown in the figure. Furthermore, in this embodiment, the connecting post 213 is perpendicular to the second surface 2112 of the rigid component 210. In this embodiment, the rigid component 210 and the connecting post 213 protruding from the second surface 2112 of the rigid component 210 are integrally formed structures, ensuring a stable connection between the rigid component 210 and the connecting post 213.

[0275] In this embodiment, the pivot 220 includes a connecting rod 221 and a fixing part 222. The connecting rod 221 has a rod-shaped structure, with one end rotatably connected to the rigid component 210 and the other end connected to the fixing part 222. The connecting rod 221 is rotatably connected to the rigid component 210, thereby realizing the connection between the pivot 220 and the rigid component 210. When the foldable display terminal 1000 is as follows... Figure 1 In the unfolded state shown, the extension direction of the connecting rod 221 of the two pivot members 220 is the width direction of the rigid member 210 (i.e., as shown). Figure 8The rotation axis of the connecting rod 221 is perpendicular to the second surface 2112 of the hard material 210 (i.e., the direction of the X-axis shown in FIG. 2). In this embodiment, the rotation axis of the connecting rod 221 is perpendicular to the hard material 210, that is, the extension direction of the rotation axis of the connecting rod 221 is perpendicular to the second surface 2112 of the hard material 210. It can be understood that in other embodiments of the present application, the rotation axis of the connecting rod 221 can also be at an angle to the hard material 210, that is, the extension direction of the rotation axis of the connecting rod 221 is not perpendicular to the second surface 2112 of the hard material 210.

[0276] In this embodiment of the present application, the connecting rod 221 and the fixed portion 222 are an integral structure obtained by integral molding, and there is no obvious boundary between the connecting rod 221 and the fixed portion 222. The connecting rod 221 and the fixed portion 222 of the integral structure obtained by the molding method of integral molding can ensure a more firm connection relationship between the connecting rod 221 and the fixed portion 222, and can simplify the molding process of the rotation shaft 220.

[0277] In this embodiment, the connecting rod 221 includes oppositely arranged first and second rod surfaces 2211 and 2212. The first rod surface 2211 faces the hard material 210, and the second rod surface 2212 faces away from the hard material 210.

[0278] Please refer to Figure 29 and Figure 30 In this embodiment, the first rod surface 2211 is recessed in the direction of the second rod surface 2212 and the slot hole 224 is located at the end of the connecting rod 221 away from the fixed portion 222. The connecting column 213 on the hard material 210 can be inserted into the slot hole 224 and can rotate in the slot hole 224, thereby realizing the rotation of the hard material 210 of the rotation shaft 220, realizing the rotation of the connecting rod 221 relative to the hard material 210 with the connecting column 213 as the rotation axis, and realizing the rotation connection between the rotation shaft 220 and the hard material 210. In this embodiment, the connecting column 213 and the slot hole 224 on the rotation shaft 220 are both cylindrical, thereby facilitating the rotation of the connecting column 213 in the slot hole 224.

[0279] In this embodiment, the extension direction of the slot hole 224 is perpendicular to the second surface 2112 of the hard material 210, and the connecting column 213 is perpendicular to the second surface 2112 of the hard material 210. Therefore, the connecting column 213 is inserted into the slot hole 224 to realize the connection between the connecting rod 221 and the hard material 210, the rotation axis of the connecting rod 221 is the connecting column 213, and the rotation axis direction of the connecting rod 221 is perpendicular to the hard material 210.

[0280] It can be understood that, in some other embodiments of the present application, the rotary connection between the connecting rod 221 and the rigid piece 210 can also be connected through other ways. For example, in some embodiments, the connecting rod 221 and the rigid piece 210 can be connected through a hinge joint, so as to realize the connection between the connecting rod 221 and the rigid piece 210. Alternatively, in some embodiments, a connecting column 213 can be protruded on the second surface 2112 of the rigid piece 210, and a slot hole 224 can be provided on the end of the connecting rod 221 away from the fixed part 222, the connecting column 213 is inserted into the slot hole 224, and the connecting column 213 can rotate in the slot hole 224, so as to realize the rotary connection between the rotating shaft piece 220 and the rigid piece 210.

[0281] Referring to Figure 30 In some embodiments, a convex ring 2131 can be further protruded on the peripheral wall of the connecting column 213, and a concave ring 2241 matched with the convex ring 2131 can be recessed on the inner wall of the slot hole 224. The convex ring 2131 is embedded in the concave ring 2241, so as to limit the movement of the rotating shaft piece 220 in the axial direction of the connecting column 213, and ensure the stable connection between the rotating shaft piece 220 and the rigid piece 210, avoiding the separation of the rotating shaft piece 220 from the rigid piece 210 during the rotation, without affecting the rotation of the rotating shaft piece 220 relative to the rigid piece 210.

[0282] In some embodiments, the surface of the convex ring 2131 can be an arc surface, so that the connecting column 213 can be more easily installed into the slot hole 224.

[0283] Referring to Figure 30 In some embodiments, there is a gap between the first rod surface 2211 and the rigid piece 210, which can ensure that the connecting rod 221 will not rub against the rigid piece 210 when the rotating shaft piece 220 rotates, so as to ensure the smoothness of the rotation of the rotating shaft piece 220, and avoid the damage caused by the friction between the connecting rod 221 and the rigid piece 210. In some embodiments, the first rod surface 2211 of the connecting rod 221 is parallel to the second surface 2112 of the rigid piece 210, so as to ensure that the distance between each position of the first rod surface 2211 of the connecting rod 221 and each position of the second surface 2112 of the rigid piece 210 is the same, reduce the size of the gap between the connecting rod 221 and the rigid piece 210, and thus reduce the entry of water, dust and other impurities from the outside into the folding display terminal 1000 through the gap between the connecting rod 221 and the rigid piece 210.

[0284] The connecting rod 221 further comprises a third rod surface 2213 connected between the first rod surface 2211 and the second rod surface 2212.

[0285] Referring to Figure 34 , Figure 35 and Figure 36 , Figure 34For Figure 28 The edge protection structure 100 shown in FIG. 1 is used to replace the edge protection structure 100 in the folding display terminal 1000 shown in FIG. 1A. Figure 1 FIG. 1B is a schematic view of the position I of the folding display terminal 1000 after the edge protection structure 100 shown in FIG. 1 is used to replace the edge protection structure 100 in the folding display terminal 1000 shown in FIG. 1A.

[0286] Figure 35 FIG. 1C is a schematic view of the edge protection structure 100 shown in FIG. 1. Figure 28 The edge protection structure 100 shown in FIG. 1 is used to replace the edge protection structure 100 in the folding display terminal 1000 shown in FIG. 1A. Figure 1 FIG. 1D is a schematic view of the position relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 after the edge protection structure 100 shown in FIG. 1 is used to replace the edge protection structure 100 in the folding display terminal 1000 shown in FIG. 1A. Figure 36 FIG. 1E is a schematic view of the edge protection structure 100 shown in FIG. 1. Figure 34 FIG. 1F is a schematic view of the edge protection structure 100 shown in FIG. 1 along the position C-C. When the edge protection structure 100 is fixed to the rotating shaft assembly 303, the fixed end 212 of the hard piece 210 of the edge protection structure 100 is fixed to the fixed shaft 3031 of the rotating shaft assembly 303. The connecting end 211 of the hard piece 210 of each of the two edge protection structures 100 is located on one side of the side surface 204 of the display screen 200 and in the length extension direction of the bending area 2001 of the display screen 200. The connecting rod 221 of each of the two edge protection structures 100 is located on one side of the display surface 203 of the display screen 200, i.e., the connecting rod 221 is located on the side of the display screen 200 away from the fixed shaft 3031, and the third rod surface 2213 of the connecting rod 221 faces the display screen 200, and the connecting rod 221 covers the edge of the bending area 2001 of the display screen 200. In the embodiments of the present application, the hard piece 210 is located on one side of the side surface 204 of the display screen 200 and in the length extension direction of the bending area 2001 of the display screen 200. The connecting rod 221 covers the edge of the bending area 2001 of the display screen 200, i.e., the edge of the bending area 2001 of the display screen 200 is wrapped by the hard piece 210 and the connecting rod 221, so as to avoid the exposure of the edge of the bending area 2001 of the display screen 200, improve the appearance effect of the folding display terminal 1000, and prevent the edge of the bending area 2001 of the display screen 200 from being damaged by collision.

[0287] In addition, in some embodiments of the present application, there is a certain gap between the edge of the bending area 2001 of the display screen 200 and the hard piece 210. When the folding display terminal 1000 is subjected to collision, the collision force is applied to the hard piece 210 and is not easily transmitted to the display screen 200 to damage the display screen 200, further improving the reliability of the folding display terminal 1000.

[0288] Please refer to Figure 36In this embodiment, the third rod surface 2213 is a plane. When the bending area 2001 of the display screen 200 is unfolded, each position of the third rod surface 2213 can contact the surface of the display screen 200 facing away from the pivot assembly 303, reducing the gap between the display screen 200 and the connecting rod 221, and reducing the entry of water, dust, etc. into the folding display terminal 1000 through the gap between the display screen 200 and the connecting rod 221. Furthermore, it avoids the problem of the display screen 200 being damaged by a protrusion on the third rod surface 2213. It is understood that in some other embodiments of this application, the third rod surface 2213 may also be an arc surface that is slightly convex outward toward the display screen 200 or slightly concave inward away from the display screen 200. When the bending area 2001 of the display screen 200 is unfolded, there is a slight distance between each position of the third rod surface 2213 and the surface of the display screen 200 facing the connecting rod 221, ensuring that the third rod surface 2213 will not cause local pressure on the display screen 200 and damage the display screen 200.

[0289] Please refer to it again. Figure 36 In some embodiments of this application, the connecting rod 221 further includes an end face 2214, which is located at the end of the connecting rod 221 connected to the rigid member 210, and connects the first rod face 2211, the second rod face 2212, and the third rod face 2213. In this embodiment, the end face 2214 is an arc surface with the rotation axis of the connecting rod 221 as the central axis. The end faces 2214 of the connecting rods 221 of the two rotating members 220 connected to the rigid member 210 are arranged opposite to each other. In this embodiment, since the end face 2214 is an arc surface, it can be ensured that the distance between the end faces 2214 of the two connecting rods 221 remains the same during rotation, thereby ensuring that the two rotating members 220 connected to the rigid member 210 will not collide, achieving a good rotation effect.

[0290] Please see Figure 37 , Figure 37 As shown Figure 34 The diagram shows a partial cross-sectional view of the foldable display terminal 1000 after it has been cut open along position CC. The foldable display terminal 1000 of this embodiment is... Figure 36 The foldable display terminal 1000 shown has a basically the same structure, the difference being that in this embodiment, the end faces 2214 of the two connecting rods 221 of the edge protection structure 100 of the foldable display terminal 100 are provided with engaging teeth 2215, and the engaging teeth 2215 on the arc surfaces of the two connecting rods 221 mesh. Therefore, when one rotating shaft 220 is rotated, the other rotating shaft 220 can rotate synchronously, thereby achieving a better rotation experience.

[0291] Please refer to the previous document. Figure 28 and Figure 29The fixing part 222 includes a first surface 2221 and a second surface 2222 disposed opposite to each other, wherein the first surface 2221 faces the rigid member 210, and the second surface 2222 is located on the side of the first surface 2221 facing away from the rigid member 210. In this embodiment, the second surface 2222 of the fixing part 222 contacts and connects with the first rod surface 2211 of the connecting rod 221, that is, the fixing part 222 is located on the side of the connecting rod 221 facing the rigid member 210. When the edge protection structure 100 is installed on the folding display terminal 1000, the connecting rod 221 covers the edge of the bending area 200 of the display screen 200. Since the fixing part 222 is located on the side of the connecting rod 221 facing the rigid member 210, the fixing part 222 can always be located between the display screen 200 and the frame 304.

[0292] In this embodiment, the fixing part 222 and the connecting rod 221 of the rotating shaft 220 are made of the same material, and the fixing part 222 and the connecting rod 221 are an integral structure formed by integral molding. The molding process of the rotating shaft 220 is simple, and the connection between the fixing part 222 and the connecting rod 221 is more stable. It should be noted that in this embodiment, since the fixing part 222 and the connecting rod 221 of the rotating shaft 220 are an integral structure formed of the same material, there is no obvious connection interface between the fixing part 222 and the connecting rod 221. Therefore, in this embodiment, the fixing part 222 and the connecting rod 221 of the rotating shaft 220 are actually two artificially divided parts for ease of explanation. It is understood that in other embodiments of this application, the fixing part 222 and the connecting rod 221 can also be connected by other connection methods such as welding, bonding, or snap-fitting to form a separate structure.

[0293] In this embodiment, a limiting protrusion 223 is further provided on the first surface 2221 of the fixing part 222, and the limiting protrusion 223 is located at the end of the fixing part 222 away from the connecting rod 221. Please refer to the following: Figure 6 and Figure 37a , Figure 37a The first body 301 of the foldable display terminal 1000, which is another embodiment of this application, is in Figure 6 An enlarged view of position II shown. In the foldable display terminal 1000 of this application embodiment, the first section 3041A and the second section 3041B of the frame 3041 of the first main body 301 and the second main body 302 are each provided with a sliding groove 308 near the end of the pivot assembly 303, and the sliding groove 308 on the first section 3041A and the sliding groove 308 on the second section 3041B are arranged opposite to each other.

[0294] Please refer to it again. Figure 35 and Figure 36When the rigid component 210 of the edge protection structure 100 is fixed to the hinge assembly 303, the rigid component 210 is located on one side of the side 204 of the display screen 200 and in the length extension direction of the bending area 2001 of the display screen 200. The connecting rod 221 of the hinge component 220 is located on the side of the display screen 200 away from the hinge assembly 303. The fixing part 222 is located between the display screen 200 and the frame 3041, and the limiting protrusion 223 on the fixing part 222 is embedded in the sliding groove 308 on the frame 3041 and can slide within the sliding groove 308. In this application, since the fixing part 222 is located on the side of the connecting rod 221 facing the rigid component 210, the fixing part 222 can always be located between the display screen 200 and the frame 304, ensuring that the limiting protrusion 223 on the fixing part 222 can always be located within the sliding groove 308 on the frame 3041 and can slide within the sliding groove 308. In this embodiment, edge protection structures 100 are provided on both sides of the bending area 2001 of the display screen 200. The limiting protrusions 223 of the two pivot members 220 of the edge protection structure 100 on one side of the bending area 2001 are respectively located in the groove 308 of the first section 3041A of the first frame and the groove 308 of the first section 3041A of the second frame. The limiting protrusions 223 of the two pivot members 220 of the edge protection structure 100 on the other side of the bending area 2001 are respectively located in the groove 308 of the second section 3041B of the first frame and the groove of the second section 3041B of the second frame.

[0295] Please see Figure 38 , Figure 38 As shown Figure 29 The diagram shows an exploded view of the edge protection structure 100 from another perspective. In this embodiment, the fixing part 222 includes a first end 222a and a second end 222b disposed opposite to each other. The first end 222a of the fixing part 222 is connected to the connecting rod 221, and a limiting protrusion 223 is disposed at the second end 222b of the fixing end 212. In this embodiment, the second end 222b is closer to the reference plane than the first end 222a, and the reference plane is located on the side of the fixing end 212 away from the connecting end 211. In other words, when the foldable display terminal 1000 unfolds to... Figure 1 In the flattened state shown, the second end 222b extends relative to the first end 222a in the direction from the display screen 200 to the screen support assembly 300 (i.e., Figure 1The positive direction of the Z-axis is ensured to be always between the display screen 200 and the frame 3041 during the folding process of the folding display terminal 1000, and the limiting protrusion 223 on the fixing part 222 is embedded in the sliding groove 308 on the frame 3041. It should be noted that the reference plane in the present application is not an actually existing plane, but a virtual plane defined for the purpose of clearly indicating the relative positions of one end of the limiting protrusion 223 provided on the fixing part 222 and one end of the fixing part 222 connected with the connecting rod 221.

[0296] In the present embodiment, the track of the sliding groove 308 is designed according to the track of the movement of the limiting protrusion 223 of the edge protection structure 100 when the folding display terminal 1000 is bent, so that when the folding display terminal 1000 is bent, the bending area 2001 of the display screen 200 is bent, and the first main body 301 and the second main body 302 are folded around the hinge assembly 303 as the axis, the limiting protrusion 223 of the hinge part 220 can slide in the sliding groove 308 accordingly, and the hinge part 220 is driven to rotate accordingly, so that the rotation of the hinge part 220 is always synchronized with the bending of the display screen 200 during the bending process of the folding display terminal 1000, and the display screen 200 does not need to push the hinge part 220 to make the hinge part 220 rotate, that is, there is no force between the display screen 200 and the hinge part 220, so that the force between the display screen 200 and the hinge part 220 is avoided to cause damage to the display screen 200. In the present embodiment, the sliding groove 308 is a slightly curved free curve.

[0297] Please refer to Figures 39-41 , Figure 39 The edge protection structure 100 shown in Figure 28 The edge protection structure 100 shown in Figure 1 The edge protection structure 100 of the folding display terminal 1000 shown in Figure 1 The structure state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 shown in Figure 40 The edge protection structure 100 shown in Figure 28 The edge protection structure 100 shown in Figure 1 The edge protection structure 100 of the folding display terminal 1000 shown in Figure 2 The structure state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 shown in Figure 41 The edge protection structure 100 shown in Figure 28 The edge protection structure 100 shown in Figure 1 The edge protection structure 100 of the folding display terminal 1000 shown in Figure 3The structure state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 when folded to the fully closed state is shown in the middle. In this embodiment, there is no force between the display screen 200 and the shaft member 220 when the folding display terminal 1000 is in different states. When the folding display terminal 1000 is bent, the shaft area of the display screen 200 can be naturally bent. The limiting protrusion 223 of the shaft member 220 of the edge protection structure 100 slides in the sliding groove 308 of the first body 301 and the second body 302, so that the shaft member 220 of the edge protection structure 100 is driven to rotate relative to the hard member 210 by the first body 301 and the second body 302. In this embodiment, when the display screen 200 is fully folded, the first fixed area 200a and the second fixed area 200b of the display screen 200 can be attached, and the shaft area 200c of the display screen 200 can be naturally bent. This avoids damage to the display screen 200 caused by excessive folding, and can ensure the service life of the display screen 200.

[0298] In the present embodiment, the hard member 210 and the shaft member 220 are made of a material with a certain strength. Specifically, in this embodiment, the hard member 210 and the shaft member 220 can be metal members formed of metal materials. The metal materials forming the hard member 210 and the shaft member 220 can be various types of metal materials or alloy materials such as stainless steel, cast iron, aluminum, etc. It can be understood that in other embodiments of the present application, the hard member 210 and the shaft member 220 can also be formed of other types of structural members. For example, in some embodiments, the hard member 210 or the shaft member 220 can be a fine ceramic member formed of a fine ceramic material. In this embodiment, the hard member 210 and the shaft member 220 both have a certain strength, so as to have a good anti-collision effect, and to ensure that the bending area 2001 of the display screen 200 is not easily damaged by collision. Moreover, the hard member 210 or the shaft member 220 is made of a material with high strength, which can reduce damage caused by collision or wear and tear and improve the service life of the edge protection structure 100.

[0299] In this embodiment, the hard material 210 and the rotating shaft 220 can be obtained by metal injection molding (MIM). In this embodiment, the hard material 210 obtained by metal injection molding has high dimensional accuracy, which facilitates the cooperation of the edge protection structure 100 and other structures of the foldable display terminal 1000. In addition, the hard material 210 obtained by metal injection molding has uniform structure and high relative density at each position, thereby having high strength and being capable of achieving better protection effect on the edge of the display screen 200. In addition, the hard material 210 has good surface finish, so that the foldable display terminal 1000 can have better appearance effect. It can be understood that in other embodiments of the present application, the hard material 210 can also be formed by other processes, for example, by computer numerical control (CNC) machining, die casting, etc.

[0300] In some embodiments of the present application, the surfaces of the hard material 210 and the rotating shaft 220 can be coated with a plating layer to further improve the appearance effect of the edge protection structure 100. For example, in some embodiments, the plating layer on the surface of the hard material 210 has the same color as the back shell of the foldable display terminal 1000, so that the appearance color of the foldable display terminal 1000 is uniform, thereby having better appearance effect. In some embodiments, the plating layer can also block water, oxygen and other external factors from corroding the hard material 210, thereby improving the quality of the foldable display terminal 1000.

[0301] In the present application, the plating layer can be formed by evaporation process or deposition process, and the forming method of the plating layer is not limited herein.

[0302] In the embodiment, the edge protection structure 100 is fixed to the rotating shaft assembly 303, and the hard piece 210 of the edge protection structure 100 is located at one side of the side surface 204 of the display screen 200, and the hard piece 210 is located in the length extension direction of the bending area 2001 of the display screen 200, and the connecting rod 221 covers the edge of the bending area 2001 of the display screen 200, that is, the edge of the bending area 2001 of the display screen 200 is wrapped by the hard piece 210 and the connecting rod 221, so as to avoid the edge of the bending area 2001 of the display screen 200 from being exposed, improve the appearance effect of the folding display terminal 1000, and prevent the edge of the bending area 2001 of the display screen 200 from being damaged due to collision. In addition, the limiting protrusion 223 of the edge protection structure 100 is installed in the sliding groove 308 of the first main body 301 and the second main body 302, so that in the folding and unfolding process of the folding display terminal 1000, the rotating shaft piece 220 of the edge protection structure 100 is pushed to rotate by the first main body 301 and the second main body 302, so as to avoid the action force between the bending area 2001 of the display screen 200 and the rotating shaft piece 220, thereby ensuring that the bending area 2001 of the display screen 200 can be naturally bent, so as to ensure the service life of the display screen 200.

[0303] Please refer to Figure 42 、 Figure 43 and Figure 44 , Figure 42 which are structural schematic diagrams of the edge protection structure 100 according to the eighth embodiment of the present application; Figure 43 which is an exploded structural schematic diagram of the edge protection structure 100 shown in Figure 42 ; Figure 44 which is a sectional schematic diagram of the edge protection structure 100 shown in Figure 42 . In the embodiment, the edge protection structure 100 comprises an elastic sheet 310 and a flexible piece 320. The elastic sheet 310 comprises a first section 311, a second section 312 and a third section 313, and the second section 312 and the third section 313 are connected to the two sides of the first section 311, respectively. The flexible piece 320 is laminated on the elastic sheet 310 and covers the first section 311 of the elastic sheet 310.

[0304] Please refer to Figure 45 、 Figure 46 and Figure 47 , Figure 45 which are enlarged schematic diagrams of the position I of the folding display terminal 1000 shown in Figure 42 after the edge protection structure 100 shown in Figure 1 is replaced by the edge protection structure 100 shown in Figure 46 ; Figure 45 which is a schematic diagram of the positional relationship between the edge protection structure 100 and other structures of the folding display terminal 1000 shown in Figure 45 .Figure 47 is shown from Figure 45 The cross-sectional view is taken at position II-II. When the edge protection structure 100 is installed on the folding display terminal 1000, the edge protection structure 100 is located on the side of the display screen 200 away from the screen support assembly 300, and the edge protection structure 100 corresponds to the edge position of the display screen 200. Specifically, the first section 311 of the elastic sheet 310 and the flexible piece 320 are opposite to the bending area 2001 of the display screen 200 and cover the edge of the bending area 2001 of the display screen 200, so as to cover the edge of the bending area 2001 of the display screen 200 by the edge protection structure 100, avoid the edge of the bending area 2001 exposed, and improve the appearance effect of the folding display terminal 1000. At the same time, since the bending area 2001 of the display screen 200 is covered by the flexible piece 320 and the first section 311 of the edge protection structure 100, when the bending area 2001 of the display screen 200 is collided, the flexible piece 320 and the first section 311 of the edge protection structure 100 can protect the bending area 2001 of the display screen 200, so as to avoid the edge of the bending area 2001 of the display screen 200 damaged due to collision.

[0305] The second section 312 of the elastic sheet 310 is located on the side of the first edge protection piece 101 facing the display screen 200 and is fixed with the first edge protection piece 101; the third section 313 is located on the side of the second edge protection piece 102 facing the display screen 200 and is fixed with the second edge protection piece 102. In other words, the second section 312 of the elastic sheet 310 is inserted into the gap between the first edge protection piece 101 and the display screen 200 and is fixed with the first edge protection piece 101; the third section 313 of the elastic sheet 310 is inserted into the gap between the second edge protection piece 102 and the display screen 200 and is fixed with the second edge protection piece 102, so as to realize the installation of the edge protection structure 100 on the folding display terminal 1000.

[0306] Please refer to Figure 48 , Figure 48Fig. 9 is a structural schematic diagram of the edge protection structure 100 according to the ninth embodiment of the present application. In some embodiments of the present application, the edge protection structure 100 further comprises an adhesive layer 340, which is laminated to the side of the fixed part facing away from the display screen 200. In some embodiments, the adhesive layer 340 is laminated to the surfaces of the second section 312 and the third section 313 of the elastic sheet 310, and the adhesive layer 340 is on the same side of the elastic sheet 310 as the flexible piece 320. In some embodiments, the adhesive layer 340 comprises a glue layer 341 and a release film layer 342, which is on the side of the glue layer 341 facing away from the elastic sheet 310. When the edge protection structure 100 is installed on the folding display terminal 1000, the release film layer 342 of the adhesive layer 340 is removed, so that the second section 312 and the first edge protection piece 101 are fixedly bonded by the glue layer 341, and the third section 313 and the second edge protection piece 102 are fixedly bonded by the glue layer 341.

[0307] It can be understood that in other embodiments of the present application, the second section 312 and the third section 313 can also be fixed to the first edge protection piece 101 and the second edge protection piece 102 by other fixing methods such as clamping, screwing, etc.

[0308] In the embodiments of the present application, the lengths of the second section 312 and the third section 313 are within a certain range, so as to avoid that the lengths of the second section 312 or the third section 313 are too long to occupy too much internal space of the folding display terminal 1000, and also to avoid that the length of the second section 312 is too long to excessively pull the first edge protection piece 101 during the bending process, or the length of the third section 313 is too long to excessively pull the second edge protection piece 102 during the bending process. At the same time, it is also necessary to avoid that the lengths of the second section 312 and the third section 313 are too short, so as to avoid that the second section 312 is detached from the first edge protection piece 101 during the bending process, or the third section 313 is detached from the second edge protection piece 102 during the bending process.

[0309] When the folding display terminal 1000 is folded, the first body 301 and the second body 302 of the folding display terminal 1000 are close to each other from the one end of the rotating shaft assembly 303, so as to drive the display screen 200 fixed with the first body 301 and the second body 302 to fold, the first edge protection piece 10 far from the one end of the rotating shaft assembly 300 can be close to the one end of the second edge protection piece 20 far from the rotating shaft assembly 300, and the first edge protection piece 10 and the second edge protection piece 20 can drive the first section 311 of the elastic sheet 310 and the flexible piece 320 of the edge protection structure 100 to bend, so as to realize the synchronous bending of the edge protection structure 100 and the display screen 200. In the present application, the elastic sheet 310 and the flexible piece 320 of the edge protection structure 100 have good bending performance, and basically will not affect the state of the display screen 200 when bending, but can change the shape accordingly with the bending state of the display screen 200 when bending, so that the first fixed area 200a and the second fixed area 200b of the display screen 200 can be attached, and the rotating shaft area 200c of the display screen 200 can be naturally bent when the display screen 200 is completely folded in the present application. In other words, in the present application, the edge protection structure 100 provided in the folding display terminal 1000 can realize the protection of the edge of the bending area 100c of the display screen 100 of the folding display terminal 1000, and improve the appearance effect of the folding display terminal 1000, without affecting the folding of the display screen 100 of the folding display terminal 100 and the reliability of the display screen 200. Please refer to Figures 49-51 , Figure 49 , Figure 42 , Figure 1 , Figure 1 , Figure 50 , Figure 42 , Figure 1 , Figure 2 , Figure 51 , Figure 42 , Figure 1 , Figure 3A structural state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 when folded to a fully closed state is shown in FIG. 1C.

[0310] In the embodiments, the elasticity of the elastic sheet 310 is greater than the elasticity of the flexible member 320, so that the edge protection structure 100 does not deform greatly after being bent for many times, and the bending life of the edge protection structure 100 is ensured. In some embodiments, the flexibility of the elastic sheet 310 is less than the flexibility of the flexible member 320. The flexibility of the elastic sheet 310 is less than the flexibility of the flexible member 320, so that the flexible member 320 can be well supported. In addition, the flexibility of the flexible member 320 is good, so that the influence of the flexible member 320 on the bending performance of the edge protection structure 100 is reduced. In addition, when the edge protection structure 100 is installed on the folding display terminal 1000, the flexible member 320 is located on the side of the elastic sheet 310 away from the flexible member 320. That is, the flexible member 320 is close to the outside of the folding display terminal 1000 relative to the elastic sheet 310. When the folding display terminal 1000 is impacted, the impact position is generally on the flexible member 320. Because the flexible member 320 has good flexibility, a good buffering effect can be achieved, and the force generated by the impact can be prevented from being transmitted to the display screen 200 through the elastic sheet 310, so that the display screen 200 is well protected.

[0311] In the embodiments, the elastic sheet 310 can be a high-modulus plastic sheet or a metal sheet. For example, the elastic sheet 310 can be a high-modulus polyethylene terephthalate (PET) sheet, a high-modulus polyimide (PI) sheet, or a steel sheet. It can be understood that the elastic sheet 310 of the present application can also be formed of other materials that can achieve elastic deformation, which are not listed one by one here. By making the elastic sheet 310 relatively thin, the elastic sheet 310 can have a certain elasticity, so that the elastic sheet 310 can be bent many times with the folding display terminal 1000, and the service life of the elastic sheet 310 is ensured. In addition, by making the elastic sheet 310 relatively thin, the elastic sheet 310 can have a certain elasticity, and the edge protection structure 100 can be bent synchronously with the display screen 200, so that the interaction force between the edge protection structure 100 and the display screen 200 is avoided to damage the display screen 200, and the folding effect of the folding display terminal 1000 is also avoided. In some embodiments, the thickness of the elastic sheet 310 can be less than or equal to 0.1 mm.

[0312] In the present application, the flexible member 320 can be made of silica gel, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC) soft glue, rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene butadiene rubber, and isoprene rubber), or the like. It can be understood that the soft glue member 30 of the present application can also be formed of other flexible materials, which are not listed one by one here.

[0313] Please refer back to Figure 42 , Figure 43 and Figure 44 In the present embodiment, the elastic sheet 310 is a metal sheet, and the flexible member 320 is a plastic member. The flexible member 320 is adhered to the elastic sheet 310 by the adhesive layer 330. It can be understood that in other embodiments of the present application, the flexible member 320 and the elastic sheet 310 can also be fixed by other means. For example, in some embodiments of the present application, the flexible member 320 and the elastic sheet 310 can be obtained by integral molding. Specifically, the elastic sheet 310 is first formed, then the elastic sheet 310 is placed in a mold, and then a plastic material is injected into the mold to form the flexible member. That is, the elastic sheet 310 and the flexible member 320 are integrally molded to form an integral structure by injection molding. By integrally molding the flexible member 320 and the elastic sheet 310 to form an integral structure, the connection between the flexible member 320 and the elastic sheet 310 can be more secure.

[0314] In some embodiments, the surface of the edge protection structure 100 can be coated with a plating layer to improve the appearance effect of the edge protection structure 100. For example, in some embodiments, the surface of the edge protection structure 100 or the surface of the flexible member 320 of the edge protection structure 100 is coated with a plating layer, so that the edge protection structure 100 or the flexible member 320 of the edge protection structure 100 can have the same color as the back cover of the folding display terminal 1000, thereby making the appearance color of the folding display terminal 1000 uniform and having a better appearance effect. In some embodiments, the plating layer can also block water, oxygen, and the like from the outside from corroding the edge protection structure 100, thereby improving the quality of the folding display terminal 1000.

[0315] In the present application, the plating layer can be formed by evaporation deposition process or deposited by vapor deposition, and the formation method of the plating layer is not specifically limited here.

[0316] In some embodiments of the present application, the surface of the elastic sheet 310 is smoother than the surface of the flexible member 320. In the present application, when the edge protection structure 100 is mounted on the folding display terminal 1000, the elastic sheet 310 of the edge protection structure 100 is stacked on the display screen 200 and contacts the edge of the display screen 200. In the embodiments of the present application, when the surface of the elastic sheet 310 is smoother, the friction between the elastic sheet 310 and the display screen 200 can be reduced, so that the elastic sheet 310 and the display screen 200 are not pulled due to the friction during the bending of the folding display terminal 1000, thereby ensuring the smooth bending of the folding display terminal 1000 and avoiding damage to the display screen 200 caused by the pulling between the elastic sheet 310 and the display screen 200, and improving the reliability of the folding display terminal 1000.

[0317] In the embodiments of the present application, the elastic sheet 310 can be made of polyethylene terephthalate (PET), high-modulus polyimide (PI), or steel sheet, etc. by rolling or other forming methods, so that a higher surface smoothness and a thinner sheet can be obtained. In the embodiments of the present application, the flexible member 320 is made of rubber, silicone, etc. by injection molding or other forming methods, so that the flexible member 320 required by the present application can be obtained by a simple forming method. It can be understood that in the embodiments of the present application, the flexible member 320 and the elastic sheet 310 with a thinner thickness and a smoother surface can also be made by other manufacturing methods, which are not limited here.

[0318] Please refer back to Figure 42 , Figure 43 and Figure 44 In some embodiments of the present application, the width of the middle position of the first section 311 is smaller than the width of the two sides close to the second section 312 and the third section 313. In the present embodiment, the width direction of the first section 311 is the Y direction shown in Figure 42 , and the width direction of the second section 312 and the third section 313 is the X direction shown in Figure 4The width of the middle position of the first section 311 is smaller than the width of the two sides close to the second section 312 and the third section 313, so that the bending performance of the middle position of the first section 311 is better than the bending performance of the two end positions close to the second section 312 and the third section 313. When the folding display terminal 1000 is folded, the bending position of the edge protection structure 100 is at the middle position of the first section 311, so as to reduce the bending of the two end positions of the first section 311 connected with the second section 312 and the third section 313, reduce the pulling of the first section 311 to the second section 312 and the third section 313, and reduce the risk that the second section 312 is forced to separate from the first edge protection piece 101 and the risk that the third section 313 is forced to separate from the second edge protection piece 102. In addition, when the folding display terminal 1000 is bent, the bending degree of the middle position of the bending area 1001 of the display screen 100 is the largest. In the embodiment of the present application, the bending performance of the middle position of the first section 311 is better than the bending performance of the two end positions close to the second section 312 and the third section 313, and the middle position of the first section 311 is opposite to the middle position of the bending area 1001, so as to ensure that the edge protection structure 100 can be bent and deformed synchronously with the display screen 200, without generating a large force on the display screen 200 to damage the display screen 200.

[0319] Please refer to Figure 43 In some embodiments of the present application, the first section 311 includes a first surface 3111 and a second surface 3112 oppositely arranged in the width direction, and a notch 3113 is formed in the middle position of the first surface 3111 to the second surface 3112, so that the width of the middle position of the first section 311 is smaller than the width of the two sides close to the second section 312 and the third section 313. It can be understood that in some other embodiments of the present application, the first surface 3111 can be an arc surface concave to the second surface 3112, so that the width of the middle position of the first section 311 is smaller than the width of the two sides close to the second section 312 and the third section 313.

[0320] In some embodiments of the present application, the width of the second section 312 and the third section 313 is substantially the same as the width of the first section 311. It should be noted that the width of the second section 312 and the third section 313 is substantially the same as the width of the first section 311 in the present application, which means that the width of the second section 312 and the third section 313 can be substantially the same as the width of the first section 311, or the width of the second section 312 and the third section 313 can be slightly larger or slightly smaller than the width of the first section 311. Figure 42In the illustrated embodiment, the widths of the second segment 312 and the third segment 313 are slightly smaller than the width of the first segment 311. The width directions of the second segment 312 and the third segment 313 are the same as those of the first segment 311, all perpendicular to the connection direction between the second segment 312 / 313 and the first segment 311. Figure 4 The Y-axis direction is shown in the diagram. In this application, since the second segment 312 and the third segment 313 are connected to both sides of the first segment 311, when the second segment 312 on both sides of the first segment 311 is fixed to the side of the first edge protection member 101 facing the display screen 200, and the third segment 313 is fixed to the side of the second edge protection member 102 facing the display screen 200, the first segment 311 can be tensioned by the second segment 312 and the third segment 313. Furthermore, since the width of the second segment 312 and the third segment 313 is basically the same as the width of the first segment 311, the fixing of the second segment 312 and the third segment 313 can tension various positions in the width direction of the first segment 311, avoiding the problem of warping after multiple bends.

[0321] When the bending area 2001 of the display screen 200 is bent, the first segment 311 of the soft rubber component also bends synchronously with the display screen 200. After the first segment 311 undergoes multiple bends with the display screen 200, it is prone to plastic deformation, causing both ends of the first segment 311 to warp away from the display screen 200. In this embodiment, the two ends of the first segment 311 are fixed by the second segment 312 and the third segment 313, thereby avoiding the problem of warping after multiple bends.

[0322] In some embodiments, the width of the flexible member 320 at its middle position is smaller than the width of its ends near the second segment 312 and the third segment 313. In this embodiment, the flexible member 320 and the elastic sheet 310 have the same width direction. Figure 42The middle position of the flexible member 320 has a smaller width than the two sides close to the second section 312 and the third section 313, so that the bending performance of the middle position of the flexible member 320 is better than the bending performance of the two sides close to the second section 312 and the third section 313. Because the width of the middle position of the flexible member 320 is small, the bending of the flexible member 320 occurs in the middle position of the flexible member 320 as much as possible. After the edge protection structure 100 is bent for many times, the flexible member 320 in the bending position of the edge protection structure 100 can be separated from the second section 312 and the third section 313. In the embodiment of the present application, because the bending of the flexible member 320 occurs in the middle position of the flexible member 320 as much as possible, the separation of the two ends of the flexible member 320 from the elastic sheet 310 can be avoided, the problem of the two ends of the flexible member 320 being raised can be avoided, and the appearance effect of the folding display terminal 1000 can be ensured. Moreover, when the folding display terminal 1000 is bent, the bending degree of the middle position of the bending area 1001 of the display screen 100 is the largest. In the embodiment of the present application, the bending performance of the middle position of the flexible member 320 is better than the bending performance of the two end positions close to the second section 312 and the third section 313, the middle position of the flexible member 320 is opposite to the middle position of the bending area 1001, so that the edge protection structure 100 can be bent and deformed synchronously with the display screen 200, and a large force is not generated on the display screen 200 to damage the display screen 200.

[0323] Specifically, please refer to Figure 43 In some embodiments of the present application, the flexible member 320 includes a first surface 3201 and a second surface 3202 arranged opposite to each other in the width direction, and a notch 3205 is formed in the middle position of the first surface 3201 and recessed towards the second surface 3202, so that the width of the middle position of the flexible member 320 is smaller than the width of the two sides close to the second section 312 and the third section 313. It can be understood that in some other embodiments of the present application, the first surface 3201 can be an arc surface recessed towards the second surface 3202, so that the width of the middle position of the flexible member 320 is smaller than the width of the two sides close to the second section 312 and the third section 313.

[0324] In some embodiments, the thickness of the middle position of the flexible member 320 is thinner than the thickness of the two ends close to the second section 312 and the third section 313, so that the bending performance of the middle position of the flexible member 320 can be further improved. The thickness direction of the flexible member 320 is the Z-axis direction shown in FIG. 12. Figure 44 The thickness direction of the flexible member 320 is the Z-axis direction shown in FIG. 12. Please refer to Figure 52 , Figure 52 FIG. 13 is a cross-sectional schematic view of an edge protection structure 100 according to a tenth embodiment of the present application. In the embodiment, the thickness direction of the flexible member 320 is the Z-axis direction shown in FIG. 12. Figure 49The flexible member 320 includes a third surface 3203 and a fourth surface 3204 oppositely arranged in the thickness direction. The third surface 3203 is away from the fourth surface 3204 relative to the elastic sheet 310. The third surface 3203 is an arc surface concaved to the fourth surface 3204, so that the thickness of the middle position of the flexible member 320 is thinner relative to the thickness of the two ends of the second section 312 and the third section 313, and the bending performance of the middle position of the flexible member 320 is better relative to the bending performance of the two ends of the second section 312 and the third section 313. It can be understood that in some other embodiments of the present application, the fourth surface 3204 can be an arc surface concaved to the third surface 3203, so that the thickness of the middle position of the flexible member 320 is smaller relative to the thickness of the two sides of the second section 312 and the third section 313. In some embodiments, the first section 311 of the elastic sheet 310 can also be arc-shaped, and the first section 311 of the elastic sheet 310 is attached to the arc-shaped fourth surface 3204. It can be understood that in some other embodiments of the present application, the thickness of the middle position of the flexible member 320 can be thinner relative to the thickness of the two ends of the second section 312 and the third section 313 by other ways such as setting a slot or a perforation in the middle position of the flexible member, which will not be described here.

[0325] Please refer to Figure 45 and Figure 47 In some embodiments of the present application, when the edge protection structure 100 is installed on the folding display terminal 1000, the third surface 3203 of the flexible member 320 is coplanar with the surface of the first edge protection member 101 or the second edge protection member 102 away from the display screen 200, so that the folding display terminal 1000 can have a more flat outer surface, and the appearance effect of the folding display terminal 1000 is improved.

[0326] In some embodiments of the present application, the width of the first section 311 can be smaller than the width of the protection member 20. In other words, when the protection member 20 covers the first section 311 of the elastic sheet 310, the edge of the protection member 20 in the width direction protrudes out of the edge of the first section 311. When the edge protection structure 100 is impacted, the impact force will act on the protection member 20. Since the protection member 20 is a flexible structure with better flexibility than the elastic sheet 310, it can better buffer the impact force, so as to avoid the impact force acting on the elastic sheet 310, and then avoid the impact force transmitted to the display screen 200 to damage the display screen 200.

[0327] In this embodiment, by covering the edge of the bending area 2001 of the display screen 200 with the first section 311 of the flexible member 320 and the elastic sheet 310 of the edge protection structure 100, the bending area 2001 of the display screen 200 can be prevented from being exposed, thereby improving the appearance of the foldable display terminal 1000. Furthermore, by covering the edge of the bending area 2001 of the display screen 200 with the flexible member 320 and the first section 311 of the elastic sheet 310 of the edge protection structure 100, the edge of the bending area 2001 of the display screen 200 can be protected, preventing damage to the edge of the bending area 2001 from impacts, thus improving the reliability of the foldable display terminal 1000.

[0328] Please see Figure 53 , Figure 54 and Figure 55 , Figure 53 The diagram shown is a schematic diagram of the edge protection structure 100 according to the eleventh embodiment of this application; Figure 54 for Figure 53 A schematic diagram of the exploded structure of the edge protection structure 100 shown; Figure 55 for Figure 53 The diagram shows a cross-sectional view of the edge protection structure 100. In this embodiment, the edge protection structure 100 includes a rigid member 410 and an elastic sheet 420 connected to the rigid member 410.

[0329] In this embodiment, the rigid component 410 includes a rigid plate 410a and a protrusion 410b. The rigid plate 410a includes a connecting surface. When the edge protection structure 100 is mounted on the hinge assembly 303, the connecting surface of the rigid plate 410a faces the side 204 of the display screen 200. The protrusion 410b is fixed to the connecting surface and protrudes away from the connecting surface. In this embodiment, the rigid plate 410a and the protrusion 410b are integral structures made of the same material through an integral molding process, thereby ensuring a stronger connection between the rigid plate 410a and the protrusion 410b and simplifying the molding process of the rigid component 410. It is understood that in other embodiments of this application, the rigid plate 410a and the protrusion 410b may also be fixed by welding, bonding, or other methods, and no specific limitations are imposed here.

[0330] In this embodiment, the hard component 410 can be a metal component formed of a metallic material, possessing high strength. In some embodiments, the metallic material forming the hard component 410 can be various types of metallic materials or alloy materials such as stainless steel, cast iron, and aluminum. It is understood that in other embodiments of this application, the hard component 410 can also be a structural component formed of other types of materials. For example, in some embodiments, the hard component 410 can be a fine ceramic component formed of a fine ceramic material.

[0331] In the embodiment, the hard material 410 can be obtained by metal injection molding (MIM). In the embodiment, the hard material 410 obtained by metal injection molding has high dimensional accuracy, which facilitates the cooperation of the edge protection structure 100 and other structures of the foldable display terminal 1000. In addition, the hard material 410 obtained by metal injection molding has uniform structure and high relative density at each position, thereby having high strength, and thus can achieve better protection effect on the edge of the display screen 200. In addition, the hard material 410 has good surface finish, so that the foldable display terminal 1000 can have a better appearance effect. It can be understood that in other embodiments of the present application, the hard material 410 can also be formed by other processes, for example, by computer numerical control (CNC) machining, die casting, etc.

[0332] In some embodiments of the present application, the surface of the hard material 410 can be coated with a plating layer to further improve the appearance effect of the edge protection structure 100. For example, in some embodiments, the plating layer on the surface of the hard material 410 has the same color as the back cover 305 of the foldable display terminal 1000, so that the appearance color of the foldable display terminal 1000 is uniform, thereby having a better appearance effect. In some embodiments, the plating layer can also block the corrosion of water, oxygen, etc. from the outside to the hard material 410, thereby improving the quality of the foldable display terminal 1000.

[0333] In the present application, the plating layer can be formed by evaporation process or deposition process, and the forming method of the plating layer is not limited herein.

[0334] Please refer to Figure 53a and Figure 54 , Figure 53a the structure diagram of another view of the edge protection structure 100 shown in Figure 53 the structure diagram of another view of the edge protection structure 100 shown in Figure 10The rigid components 110 shown have essentially the same structure. The rigid plate 410a has a plate-like structure and includes a connecting end 411 and a fixing end 412 connected to the connecting end 411. The connecting end 411 of the rigid plate 410a includes a first surface 4111 and a second surface 4112 disposed opposite to each other. The first surface 4111 is closer to the outside of the foldable display terminal 1000 than the second surface 4112, and a protrusion 410b protrudes from the second surface 4112. The fixing end 412 of the rigid plate 410a includes a third surface 4113 and a fourth surface 4114 disposed opposite to each other. The third surface 4113 is closer to the outside of the foldable display terminal 1000 than the fourth surface 4114. In this embodiment, the connection position between the connecting end 411 and the fixed end 412 of the rigid plate 410a forms a stepped structure. That is, the first surface 4111 of the connecting end 411 and the third surface 4113 of the fixed end 412 are not coplanar, and the first surface 4111 of the connecting end 411 is closer to the outside of the foldable display terminal 1000 than the third surface 4113 of the fixed end 412. The first surface 4111 of the connecting end 411 and the third surface 4113 of the fixed end 412 are connected by a fifth surface 4115. In this embodiment, the second surface 4112 and the fourth surface 4114 both face the side of the display screen 200, and the second surface 4112 and the fourth surface 4114 together form the connecting surface of the rigid plate 410a.

[0335] Please see Figure 56 , Figure 57 and Figure 58 , Figure 56 As shown Figure 55 The schematic diagram shows the partial structure of the edge protection structure 100 where the rigid component 410 is fixed to the rotating shaft assembly 303. Figure 57 As shown Figure 55 A partial exploded view of the rigid component 410 and the pivot assembly 303 of the edge protection structure 100 shown. Figure 58 As shown Figure 56 A cross-sectional view at position II-II. In this embodiment, the fixed end 412 of the rigid component 410 is fixed to the fixed shaft 3031 of the rotating shaft assembly 303, thereby fixing the edge protection structure 100 to the rotating shaft assembly 303. In this embodiment, slots 307 are provided at both ends of the fixed shaft 3031, and the fixed end 412 of the rigid component 410 is inserted into and fixed in the slots 307. In this embodiment, the fixed end 412 of the rigid component 410 is inserted into the slots 307 and fixed to the groove wall of the slots 307 by adhesive. It is understood that in other embodiments of this application, the rigid component 410 can also be fixed to the fixed shaft 3031 in other ways. For example, the rigid component 410 can be fixed to the fixed shaft 3031 by various methods such as snap-fitting and screw fixing, which will not be elaborated here.

[0336] In this embodiment of the application, when the fixed end 412 of the rigid component 410 is inserted into the slot 307 of the fixed shaft 3031, the fifth surface 4115 of the rigid component 410 contacts the surface of the fixed shaft 3031, thereby ensuring that the fixed end 412 of the rigid component 410 is more stable when inserted into the fixed shaft 3031, and is less likely to shake and fall off.

[0337] Please see Figure 58 In some embodiments, the width of the fixed end 412 is smaller than the width of the connecting end 411, and the width direction of the fixed end 412 is the same as the width direction of the connecting end 411. Figure 58 The X-axis direction is shown in the figure. When the fixed end 412 of the rigid plate 410a is inserted into the slot 307 of the fixed shaft 3031, the portion of the connecting end 411 that extends beyond the fixed end 412 in the width direction abuts against the surface of the fixed shaft 3031. This further ensures that the fixed end 412 of the rigid component 410 is more stable when inserted into the slot 307 of the fixed shaft 3031, and is less prone to shaking and falling off.

[0338] Please see Figure 56 and Figure 57 In some embodiments, when the rigid component 410 is fixed to the fixed shaft 12, the first surface 4111 of the connecting end 411 of the rigid component 410 is coplanar with the end face 3033 of the fixed shaft 3031, so that the appearance of the folding display terminal 1000 can be relatively flat and has a better appearance effect.

[0339] Please refer to the previous document. Figure 53 and Figure 54 The protrusion 410b protrudes from the side of the second surface 4112 away from the fixed end 412. The protrusion 410b includes a fixing surface 4116. The fixing surface 4116 faces the display surface 203 of the display screen 200. In this embodiment, the fixing surface 4116 may be perpendicular to the second surface 4112. The elastic sheet 420 contacts and is fixed to the fixing surface 4116. In this embodiment, an adhesive layer 440 is provided between the elastic sheet 420 and the protrusion 410b, and the elastic sheet 420 and the protrusion 410b are fixed together by the adhesive layer 440. The adhesive layer 440 may be of various types of fixing adhesive. For example, in one embodiment of this application, the adhesive layer 440 is a hot melt adhesive film layer, which fixes the elastic sheet 420 and the protrusion 410b together. It is understood that in other embodiments of this application, the elastic sheet 420 may also be fixed by a snap-fit ​​component or other means, which are not specifically limited here.

[0340] In the embodiments of the present application, the elastic sheet 420 is a strip-shaped sheet, comprising a first surface 421 and a second surface 422 arranged oppositely. The fixing surface 4116 of the protrusion 410b is in contact with the first surface 421 of the elastic sheet 420 and is fixed at the middle position of the elastic sheet 420. In the present application, the elastic sheet 420 has elasticity and can be elastically deformed. The elasticity of the elastic sheet 420 is greater than that of the rigid member 410. The protrusion 410b is fixed at the middle position of the elastic sheet 420, and the elastic sheet 420 can be bent around the protrusion 410b, i.e., the elastic sheet 420 can be folded and bent around the position where the elastic sheet 420 and the protrusion 410b are fixed, so that the two ends of the elastic sheet 420 are close to or away from each other.

[0341] In the embodiments of the present application, the elastic sheet 420 has elasticity and can be made of super-elastic shape memory alloy or high-modulus plastic material. The super-elastic shape memory alloy (SMA) has the ability of super-elastic deformation, and the deformation can be easily restored after the external force is removed. In some embodiments, the martensitic transformation temperature (Ms) of the super-elastic shape memory alloy is ≤40℃, and more than 10% of the room temperature structure is parent austenite structure, and the elastic deformation is 1% to 10%. In the embodiments of the present application, the super-elastic shape memory alloy can include but is not limited to: nickel-titanium-based (nickel-titanium, nickel-titanium-niobium, nickel-titanium-palladium, etc.), copper-based (copper-gold-zinc, copper-aluminum, copper-tin, etc.), iron-based (iron-palladium, iron-manganese-silicon, iron-nickel-cobalt-titanium, iron-nickel-cobalt-aluminum-tantalum-boron, etc.), nickel-based (nickel-manganese-gallium, nickel-iron-gallium, etc.), cobalt-based alloy (cobalt-nickel, cobalt-manganese, etc.), and other alloy systems such as gold-cadmium super-elastic shape memory alloy.

[0342] In some embodiments, the elastic sheet 420 may also be made of a high-modulus plastic material. The elastic modulus Em of the elastic sheet 420 is ≥2000MPa. For example, in some embodiments of this application, the elastic sheet 420 may be a high-modulus polyethylene terephthalate (PET) sheet or a high-modulus polyimide (PI) sheet. It is understood that the elastic sheet 420 of this application may also be formed of other materials capable of elastic deformation, which will not be listed here. In this application, the elastic sheet 420 can be made relatively thin, thereby ensuring that the elastic sheet 420 has good elasticity, thus enabling the elastic sheet 420 to have better bending performance and to undergo multiple bends with the folding display terminal 1000, ensuring the service life of the elastic sheet 420. Furthermore, by making the elastic sheet 420 relatively thin, it is ensured that the elastic sheet 420 has a certain degree of elasticity, and that the edge protection structure 100 can be bent synchronously with the display screen 200. This avoids the interaction force between the edge protection structure 100 and the display screen 200, which could damage the display screen 200, and also avoids affecting the folding effect of the folding display terminal 1000. In some embodiments of this application, the thickness of the elastic sheet 420 can be less than or equal to 0.1 mm, that is, the thickness of the elastic sheet 420 is relatively thin, thereby avoiding increasing the thickness of the folding display terminal 1000.

[0343] Please see Figure 59 , Figure 60 and Figure 61 , Figure 59 for Figure 53 The edge protection structure shown is 100 replacements. Figure 1 The enlarged view of position I of the foldable display terminal 1000 after the edge protection structure 100 in the foldable display terminal 1000 shown;

[0344] Figure 60 As shown Figure 53 A schematic diagram showing the positional relationship between the edge protection structure 100 and other structures of the foldable display terminal 1000; Figure 61 As shown Figure 59The schematic diagram of the cross section of the folding display terminal 1000 along the position III-III. In the embodiment of the present application, when the edge protection structure 100 is installed on the folding display terminal 1000, the hard plate 410a of the edge protection structure 100 is arranged on one side of the side surface 204 of the display screen 200, the connecting surface of the hard plate 410a faces the side surface 204 of the display screen 200, and the hard plate 410a is located in the length extension direction of the bending area 2001. The elastic sheet 420 of the edge protection structure 100 covers the edge of the bending area 2001 and part of the connecting area 2002 of the display screen 200. The length extension direction of the bending area 2001 is the Y direction in the figure. Figure 60 In the embodiment of the present application, the arrangement direction of the first fixed area 200a, the bending area 2001 and the second fixed area 200b of the display screen 200 is perpendicular to the length extension direction of the bending area 2001. In the embodiment of the present application, the elastic sheet 420 of the edge protection structure 100 includes a first section 421, a second section 422 and a third section 423, and the second section 422 and the third section 423 are respectively connected to the two sides of the first section 421. It should be noted that in the embodiment of the present application, there is no obvious boundary between the first section 421, the second section 422 and the third section 423, and the first section 421, the second section 422 and the third section 423 are different regions of the elastic sheet 420 divided for the convenience of description. The first section 421 is the region of the elastic sheet 420 opposite to the bending area 2001 of the display screen 200, and the first section 421 covers the edge of the bending area 2001. The second section 422 is the region of the elastic sheet 420 opposite to one connecting area 2002 of the display screen 200. The third section 423 is the region of the elastic sheet 420 opposite to the other connecting area 2002 of the display screen 200. In the present application, the hard plate 410a is arranged on one side of the side surface 204 of the display screen 200, and the hard plate 410a is arranged in the length extension direction of the bending area 2001. The elastic sheet 420 is located on one side of the display surface 203 of the display screen 200, and the first section 421 of the elastic sheet 420 covers the edge of the bending area 2001 of the display screen 200. Therefore, the edge of the bending area 2001 of the display screen 200 can be wrapped by the hard plate 410a and the elastic sheet 420, so as to avoid the edge of the bending area 2001 exposed, and improve the appearance effect of the folding display terminal 1000. Moreover, when the bending area 2001 of the display screen 200 is collided, the hard plate 410a and the first section 421 of the edge protection structure 100 can protect the bending area 2001 of the display screen 200, so as to avoid the edge of the bending area 2001 of the display screen 200 damaged due to the collision, thereby improving the reliability of the display screen 200 and the folding display terminal 1000.

[0345] Please refer to Figure 59 and Figure 61In this embodiment of the application, the second section 422 of the elastic sheet 420 is located between the first edge protection member 101 and the display screen 200, and the third section 423 of the elastic sheet 420 is located between the second edge protection member 102 and the display screen 200. That is, the first edge protection member 101 and the second edge protection member 102 can press down both ends of the elastic sheet 420, thereby preventing the two ends of the elastic sheet 420 from lifting up.

[0346] In this embodiment, the lengths of the second segment 422 and the third segment 423 are within a certain range, which avoids the second segment 422 and the third segment 423 being too long and occupying too much internal space of the folding display terminal 1000. It also avoids the second segment 422 being too short and detaching from the first edge protection member 101 and the display screen 200 during the bending process, or the third segment 423 being too short and detaching from the second edge protection member 101 and the display screen 200 during the bending process.

[0347] Please see Figures 62-64 , Figure 62 As shown Figure 53 The edge protection structure shown is 100 replacements. Figure 1 The edge protection structure 100 of the foldable display terminal 1000 is a foldable display terminal 1000 for... Figure 1 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 in the flattened state shown. Figure 63 As shown Figure 53 The edge protection structure shown is 100 replacements. Figure 1 The edge protection structure 100 of the foldable display terminal 1000 is a foldable display terminal 1000 for... Figure 2 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 when folded to the middle state. Figure 64 As shown Figure 53 The edge protection structure shown is 100 replacements. Figure 1 The edge protection structure 100 of the foldable display terminal 1000 is a foldable display terminal 1000 for... Figure 3The structure state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 when folded to the fully closed state is shown in FIG. 1C. When the folding display terminal 1000 is folded, the first body 301 and the second body 302 of the folding display terminal 1000 are close to each other from the end away from the hinge assembly 303, thereby driving the display screen 200 fixed with the first body 301 and the second body 302 to fold. In the embodiment, when the display screen 200 is folded, the elastic sheet 420 covering the edge of the hinge area 200c of the display screen 200 can follow the display screen 200 to bend and deform. In the embodiment, since the elastic sheet 420 is made of an elastically deformable material, it basically does not affect the state of the display screen 200 when it is bent, but can change the shape accordingly with the bending state of the display screen 200 when it is bent. Therefore, when the display screen 200 of the folding display terminal 1000 according to the embodiment is fully folded, the first fixed area 200a and the second fixed area 200b of the display screen 200 can be attached, thereby realizing a better folding mode. In other words, in the embodiment, the edge protection structure 100 provided in the folding display terminal 1000 can realize the protection of the edge of the bending area 2001 of the display screen 200 of the folding display terminal 1000, improve the appearance effect of the folding display terminal 1000, and will not affect the folding effect of the display screen 200 of the folding display terminal 1000 and the reliability of the display screen 200.

[0348] Please refer to Figure 53 and Figure 54 In some embodiments of the application, the edge protection structure 100 further comprises a smoothing layer 430 covering the second surface 422 of the elastic sheet 420. The smoothness of the surface of the smoothing layer 430 away from the elastic sheet 420 is greater than that of the surface of the elastic sheet 420. When the edge protection structure 100 is installed in the folding display terminal 1000, the second surface 422 of the elastic sheet 420 faces the display screen 200, and the second surface 422 can contact the display screen 200. In the embodiment, by covering the second surface 422 of the elastic sheet 420 with the smoothing layer with higher smoothness, when the edge protection structure 100 is installed in the folding display terminal 1000, the smoothing layer 430 contacts the display screen 200. Since the smoothing layer 430 has a smoother surface, the frictional force between the edge protection structure 100 and the display screen 200 can be reduced, thereby ensuring that the folding and unfolding process of the folding display terminal 1000 is smoother, and preventing the display screen 200 from being damaged due to the frictional force between the elastic sheet 420 and the display screen 200.

[0349] Please refer to Figure 65 , Figure 66 and Figure 67 , Figure 65The diagram shown is a schematic diagram of the edge protection structure 100 according to the twelfth embodiment of this application; Figure 66 As shown Figure 65 An exploded view of the edge protection structure 100 shown; Figure 67 As shown Figure 65 A cross-sectional schematic diagram of the edge protection structure 100 shown. The edge protection structure 100 of this embodiment is similar to... Figure 53 The edge protection structure 100 shown is basically the same in structure as the one described above, including a rigid component 410, an elastic sheet 420, a smooth layer 430, and an adhesive layer 440. The edge protection structure 100 of this embodiment is similar to... Figure 53 The edge protection structure 100 shown differs in that it further includes a reinforcing member 450. The reinforcing member 450 includes a first portion 451, a second portion 452, and a connection between the first portion 451 and the second portion 452. The first portion 451 is fixed to the rigid component 410. The second portion 452 passes through the elastic sheet 420 and the adhesive layer 440 and contacts the protrusion 410b. The third portion 453 is located on the side of the elastic sheet 420 facing away from the protrusion 410b. In this embodiment, the elastic sheet 420 can be confined between the third portion 453 and the protrusion 410b, thereby preventing separation between the elastic sheet 420 and the rigid component 410 when the fixation between the elastic sheet 420 and the protrusion 410b fails. Furthermore, the elastic sheet 420 is provided with a through hole 423. The end of the second part 452 away from the third part 453 passes through the through hole 423 from the second surface 422 of the elastic sheet 420 to one side of the first surface 421 of the elastic sheet 420, and contacts the protrusion 410b, thereby further reinforcing the connection between the elastic sheet 420 and the rigid member 410 and preventing the elastic sheet 420 from separating from the rigid member 410. It is understood that in some embodiments of this application, the end of the second part 452 away from the third part 453 may also pass through the through hole 423 from the second surface 422 of the elastic sheet 420 to one side of the first surface 421 of the elastic sheet 420, but there is a certain gap between it and the protrusion 410b, but it can still ensure that the elastic sheet 420 and the rigid member 410 are fixed.

[0350] In this embodiment, the smoothing layer 430 only covers the area of ​​the second surface 422 of the elastic sheet 420 except for the area opposite to the protrusion 410b. In other words, the smoothing layer 430 covers the second surface 422 of the elastic sheet 420, but the area of ​​the smoothing layer 430 opposite to the protrusion 410b is cut out. Therefore, the smoothing layer 430 does not need to cover the third part 453, which makes it easier for the smoothing layer 430 to be formed on the elastic sheet 420.

[0351] Please see Figure 67 and Figure 68 , Figure 68 To be Figure 65 The edge protection structure shown is 100 replacements.Figure 59 Figure 6 is a schematic view of a cross section along position III-III after the edge protection structure 100 shown in Figure 5 is cut. In some embodiments of the present application, a recess 4117 is formed on the fixing surface 4116 of the protrusion 410b, the recess 4117 is concave in a direction away from the elastic sheet 420, and the second part 452 is inserted into the recess 4117 at an end away from the third part 453, so that the elastic sheet 420 can be further prevented from being separated from the protrusion 410b.

[0352] Please refer back to Figure 66 and Figure 68 , Figure 66 Figure 6 is a schematic view of a cross section along position III-III after the edge protection structure 100 shown in Figure 5 is cut. In some embodiments of the present application, a recess 4117 is formed on the fixing surface 4116 of the protrusion 410b, the recess 4117 is concave in a direction away from the elastic sheet 420, and the second part 452 is inserted into the recess 4117 at an end away from the third part 453, so that the elastic sheet 420 can be further prevented from being separated from the protrusion 410b.

[0353] In some embodiments of the present application, the flexible member 460 can be made of flexible materials such as foam, rubber, and silica gel, and can be deformed by pressing, so that when the display screen 200 is bent and deformed, the flexible member 460 will not generate a large force on the display screen 200, and the problem of damage to the display screen 200 due to the extrusion of the flexible member 460 can be avoided.

[0354] Please refer back to Figure 65In some embodiments of this application, a mounting groove 413 is recessed on the connecting surface of the rigid plate 410a, with the groove opening of the mounting groove 413 facing the side where the protrusion 410b is located. In this embodiment, the mounting groove 413 is located at the connecting end 411 of the rigid plate 410a and is recessed from the second surface 4112 of the connecting end 411 toward the first surface 11. The first part 451 of the reinforcement 450 is embedded in the mounting groove 413. In this embodiment, the first part 451 and the mounting groove 413 are interference-fitted, that is, the first part 451 is slightly larger than the mounting groove 413. After the first part 451 is installed in the mounting groove 413, elastic pressure is generated between the first part 451 and the mounting groove 413, thereby obtaining a tight connection. In some embodiments, the first part 451 can also be further fixed to the mounting groove 413 by means of adhesive fixing, welding fixing, etc., so that the first part 451 and the mounting groove 413 can have a more stable fixed relationship. It is understood that in some other embodiments of this application, the rigid plate 410a may not have a mounting groove 413, and the first part 451 may be fixed to the second surface 4112 of the rigid plate 410a by means of adhesive fixing, welding fixing, etc.

[0355] In this embodiment, a rigid plate 410a of the edge protection structure 100 is disposed on one side of the side surface 204 of the display screen 200, and the rigid plate 410a is located in the length extension direction of the bending area 2001. The length extension direction of the bending area 2001 is... Figure 65 In this embodiment, the arrangement direction of the first fixed area 200a, the bending area 2001, and the second fixed area 200b of the display screen 200 intersects perpendicularly with the length extension direction of the bending area 2001. The first segment 421 of the elastic sheet 420 of the edge protection structure 100 covers the edge of the bending area 2001 of the display screen 200, that is, the edge of the bending area 2001 of the display screen 200 can be wrapped by the rigid member 410 and the elastic sheet 420, preventing the edge of the bending area 2001 from being exposed, thereby improving the appearance of the foldable display terminal 1000. Furthermore, when the bending area 2001 of the display screen 200 is impacted, the rigid member 410 and the first segment 421 of the edge protection structure 100 can protect the bending area 2001 of the display screen 200, thereby preventing the edge of the bending area 2001 of the display screen 200 from being damaged due to impact, thereby improving the reliability of the display screen 200 and the foldable display terminal 1000.

[0356] Please see Figure 69 and Figure 70 , Figure 69 The diagram shown is a schematic diagram of the thirteenth edge protection structure 100 of this application. Figure 70 As shown Figure 69An exploded schematic view of the edge protection structure 100 is shown. In the embodiment, the edge protection structure 100 includes two fixed parts 510 and a flexible part 520 connected between the two fixed parts 510. In the embodiment, the two fixed parts 510 are a first fixed part and a second fixed part respectively. Each fixed part 510 includes a fixed plate 511 and a fixed block 512 fixedly connected to the fixed plate 511. In the embodiment, the two ends of the flexible part 520 are fixed to the fixed plates 511 of the two fixed parts 510 respectively, and the flexible part 520 is located on the side of the fixed plate 511 away from the fixed block 512.

[0357] In the embodiment, the flexible part 520 is a structure part with good flexibility, and can be bent arbitrarily. In the embodiment, the flexibility of the flexible part 520 is greater than that of the fixed part 510. The flexible part 520 includes two first regions 520a arranged at intervals and a second region 520b located between the two first regions 520a. The flexible part 520 further includes a first surface 521 and a second surface 522 arranged oppositely. In the embodiment, the fixed plate 511 is fixed to the first surface 521 and is fixed to the region of the first surface 521 located in the first region 520a. The fixed plate 511 of the first fixed part and the fixed plate 511 of the second fixed part are fixedly connected to the two first regions 520a of the flexible part 520 respectively. In the embodiment, the first fixed part and the second fixed part are arranged at intervals, and the interval region between the fixed plate 511 of the first fixed part and the fixed plate 511 of the second fixed part corresponds to the second region 520b of the flexible part 520 oppositely. When the edge protection structure 100 is folded with the folding display terminal 1000, the second region 520b of the flexible part 520 will not be affected by the fixed plate 511, so as to ensure that the flexible part 520 can have a good folding effect.

[0358] In the embodiment, when the edge protection structure 100 is installed on the folding display terminal 1000, the flexible part 520 is located outside the folding display terminal 1000. When the folding display terminal 1000 is collided, the collision position is generally located on the flexible part 520. Since the flexible part 520 has good flexibility, a good buffering effect can be achieved, so as to avoid the transmission of the force generated by the collision to the display screen 200, and a good protection effect on the display screen 200 is achieved.

[0359] In some embodiments of the present application, the flexible member 520 can be made of silica gel, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU), polyvinyl chloride (PVC) soft rubber, rubber (such as silicone rubber, natural rubber, butadiene rubber, styrene butadiene rubber, and isoprene rubber), or the like. It can be understood that the flexible member 520 of the present application can also be formed of other flexible materials, which are not listed one by one.

[0360] In some embodiments of the present application, the second area 520b of the first surface 521 is concave to the second surface 522, thereby thinning the thickness of the portion of the flexible member 520 corresponding to the first area 520a, so that the flexible member 520 can have a better bending effect, and avoid the influence of the edge protection structure 100 on the folding effect of the folding display terminal 1000. Figure 69 and Figure 70 In the illustrated embodiment, the second area 520b of the first surface 521 is an arc surface concave to the second surface 522.

[0361] In some embodiments of the present application, the width of the middle section of the flexible member 520 is smaller than the width of the two ends, so that the middle section of the flexible member 520 can have a better bending effect, and ensure the protection effect of the edge protection structure 100 on the display screen, while further avoiding the influence of the edge protection structure 100 on the folding effect of the folding display terminal 1000. Figure 70 In the illustrated embodiment, the flexible member 520 further includes oppositely arranged third and fourth surfaces 523 and 524, both of which are connected between the first and second surfaces 521 and 522. When the edge protection structure 100 is installed on the folding display terminal 1000, the third surface 523 of the flexible member 520 is closer to the outer side of the folding display terminal 1000 than the fourth surface 524. In this embodiment, the middle section of the third surface 523 is concave to the fourth surface 524 to form a gap 513, so that the width of the middle section of the flexible member 520 is smaller than the width of the two ends.

[0362] Please refer back to Figure 70In some embodiments of the present application, the fixed plate 511 can be an elastic member. The elasticity of the fixed plate 511 is greater than that of the fixed block 512 and the flexible member 520, so that when the fixed plate 511 is fixedly connected with the flexible member 520, the fixed plate 511 can provide certain support to the flexible member 520. Moreover, since the fixed plate 511 also has a structure with good elasticity, the fixed plate 511 also has good bending performance, that is, the first area 520a of the flexible member 520 fixedly connected with the fixed plate 511 can also be bent, so that the edge protection structure 100 can have better bending performance, avoiding the influence of the edge protection structure 100 on the folding effect of the folding display terminal 1000. Moreover, since the fixed plate 511 has good elasticity, it can ensure that the edge protection structure 100 will not have large deformation after being bent for many times, ensuring the bending life of the edge protection structure 100.

[0363] In the embodiments of the present application, the fixed plate 511 can be a thin plate-shaped structure with good elasticity. In some embodiments, the thickness of the fixed plate 511 can be less than or equal to 0.1 mm, that is, the thickness of the fixed plate 511 is thin, so that the fixed plate 511 can have good elasticity and can avoid increasing the thickness of the folding display terminal 1000. In some embodiments of the present application, the fixed plate 511 can be a high-modulus plastic sheet or a metal sheet. For example, the fixed plate 511 can be a high-modulus polyethylene terephthalate (PET) sheet, a high-modulus polyimide (PI) sheet or a steel sheet. It can be understood that the fixed plate 511 of the present application can also be formed of other materials that can realize elastic deformation, which will not be enumerated one by one here.

[0364] In some embodiments of the present application, the fixed plate 511 includes a first section 511a and a second section 511b connected with the first section 511a, the first section 511a is connected with the flexible member 520, and the second section 511b is connected with the fixed block 512. That is, in the present embodiment, the fixed block 512 and the flexible member 520 are fixed to different sections of the fixed plate 511, so as to avoid the influence of the strength of the fixed block 512 on the bending performance of the part of the fixed plate 511 connected with the flexible member 520, thereby ensuring that each position of the flexible member 520 can have good bending performance. It should be noted that in the present embodiment, the first section 511a and the second section 511b of the fixed plate 511 are actually an integral structure connected together, and there is no obvious boundary between them. The first section 511a and the second section 511b of the present application are defined as two parts for the convenience of description of the scheme.

[0365] Please refer to Figure 70In this embodiment, the edge protection structure 100 further comprises a glue layer 530 covering one side of the first section 511a of the fixing plate 511 facing the flexible piece 520. The flexible piece 520 can be fixed to the fixing plate 511 through the glue layer 530. It can be understood that in other embodiments of the present application, the flexible piece 520 and the fixing plate 511 can also be fixed through other ways. For example, in some embodiments of the present application, the fixing plate 511 is a metal sheet and the flexible piece 520 is a plastic piece. The flexible piece 520 and the fixing plate 511 are formed through one-piece molding. Specifically, the fixing plate 511 is first formed, then the fixing plate 511 is arranged in a mold, and then plastic material is injected into the mold to form the flexible piece 520, that is, the fixing plate 511 and the flexible piece 520 are fixed together through injection molding. The flexible piece 520 and the fixing plate 511 are formed through one-piece molding to form an integrated structure, which can make the connection between the flexible piece 520 and the fixing plate 511 more firm.

[0366] Please refer again to Figure 69 and Figure 70 In some embodiments of the present application, the fixing block 512 comprises a first plate 5121 opposite to the fixing plate 511, and a second plate 5122 connecting the first plate 5121 and the fixing plate 511. In this embodiment, the fixing block 512 is located on the side of the fixing plate 511 away from the flexible piece 520. Please refer to Figure 71 and Figure 72 , Figure 71 When the edge protection structure 100 shown in Figure 69 is fixed in the folding display terminal 1000, the structure diagram of the edge protection structure 100 and the hinge assembly 303 is shown in Figure 72 Figure 71 ​FIG. 12 is a structural schematic diagram of another perspective view of the edge protection structure 100 and the hinge assembly 303. In this embodiment, when the edge protection structure 100 is fixed in the folding display terminal 1000, the flexible member 520 and the fixed plate 511 are located on the side of the fixed shaft 3031 facing the display screen, and the first section 511a of the flexible member 520 and the fixed plate 511 is opposite the fixed shaft 3031 of the hinge assembly 303, and the second section 511b of the fixed plate 511 is opposite the rotating shaft. The fixed blocks 512 of the two fixed members 510 are respectively located in the length extension direction of the two rotating shafts 3032 of the hinge assembly 303, and the fixed member 510 is fixedly connected with the rotating shaft 3032 closest to it. In other words, the fixed block 512 of the first fixed member is located in the length extension direction of the first rotating shaft and is fixedly connected with the first rotating shaft; the fixed block 512 of the second fixed member is located in the length extension direction of the second rotating shaft and is fixedly connected with the second rotating shaft. When the folding display terminal 1000 is bent, both rotating shafts 3032 rotate relative to the fixed shaft 3031, thereby driving the two fixed blocks 512 fixedly connected with the two rotating shafts 3032, respectively, to move closer to or away from each other, and further driving the first section 511a of the flexible member 520 and the fixed plate 511 opposite the fixed shaft 3031 to bend, so that the edge protection structure 100 bends with the folding display terminal 1000, avoiding the influence of the edge protection structure 100 on the bending or unfolding of the folding display terminal 1000.

[0367] In some embodiments of the present application, the edge of the door plate 3032b of the rotating shaft 3032 can be inserted between the first plate 5121 and the fixing block 512, and the door plate 3032b can be in contact with and fixed to the first plate 5121, so as to realize the fixed connection between the fixing block 512 and the rotating shaft 3032. In the present embodiment, the fixing block 512 is fixedly connected with the door plate 3032b of the rotating shaft 3032, so that a better fixed connection effect can be realized, and the influence of the fixed connection between the fixing block 512 and the rotating shaft 3032 on the rotating effect of the rotating shaft 3032 relative to the fixed shaft 3031 can be avoided. It can be understood that in other embodiments of the present application, the fixing block 512 can also be fixed to the rotating shaft 3032 in other ways. For example, in some embodiments, the fixing block 512 is located in the length extension direction of the rotating shaft 3032 and has a certain distance from the fixing block 512, and the fixing block 512 is fixed to the rotating shaft 3032 through a connecting plate. That is, the two ends of the connecting plate are fixedly connected with the fixing block 512 and the rotating shaft 3032 respectively, so that the fixing block 512 and the rotating shaft 3032 are connected and fixed through the connecting plate. It can be understood that in the present application, the fixing block 512 and the rotating shaft 3032 can also be connected in other ways, and the connection manner is not specifically limited in the present application. In the present embodiment, the first section 511a of the fixing plate 511 is opposite to the fixed shaft 3031, and the second section 511b of the fixing plate 511 is opposite to the rotating shaft 3032.

[0368] Figure 73 、 Figure 74 and Figure 75 , Figure 73 for Figure 69 the edge protection structure 100 shown in the embodiment of Figure 1 is replaced by the edge protection structure 100 shown in Figure 74 is a schematic view of the position relationship between the edge protection structure 100 shown in Figure 73 and other structures of the folding display terminal 1000; Figure 75 is a schematic view of the position relationship between the edge protection structure 100 shown in Figure 73The schematic diagram of the cross section of the folding display terminal 1000 after cutting along the position IV-IV. In the embodiment of the present application, when the edge protection structure 100 is installed on the folding display terminal 1000, the flexible piece 520 and the fixed plate 511 of the edge protection structure 100 are located on one side of the display surface 203 of the display screen 200, i.e. the flexible piece 520 and the fixed plate 511 are located on the side away from the screen support assembly 300. And, the flexible piece 520 of the present embodiment is opposite to the fixed shaft 3031 of the rotating shaft assembly 303, i.e. the flexible piece 520 is opposite to the bending area 2001 of the display screen 200. And, in the present embodiment, the flexible piece 520 can cover the edge position of the bending area 2001 of the display screen 200, avoiding the edge of the bending area 2001 to be exposed, thereby improving the appearance effect of the display terminal 1000. At the same time, since the bending area 2001 of the display screen 200 is covered by the flexible piece 520 of the edge protection structure 100, when the bending area 2001 of the display screen 200 is collided, the flexible piece 520 of the edge protection structure 100 can protect the bending area 2001 of the display screen 200, thereby avoiding the edge of the bending area 2001 of the display screen 200 to be damaged due to collision.

[0369] In the present embodiment, the first section 511a of the fixed plate 511 and the fixed block 512 of the first fixing piece of the edge protection structure 100 are located on the side of the first edge protection piece 101 facing the display screen 200; the fixed block 512 and the second section 511b of the fixed plate 511 of the second fixing piece of the edge protection structure 100 are located on the side of the second edge protection piece 102 facing the display screen 200. In other words, the fixed block 512 and the fixed plate 511 of the first fixing piece can be pressed by the first edge protection piece 101, and when the connection between the first fixing piece and the first rotating shaft is invalid, the first fixing piece can also be pressed by the first edge protection piece 101; the fixed block 512 and the fixed plate 511 of the second fixing piece can be pressed by the second edge protection piece 102, and when the connection between the second fixing piece and the second rotating shaft is invalid, the second fixing piece can also be pressed by the second edge protection piece 102, thereby further effectively avoiding the edge protection structure 100 from falling off the folding display terminal 1000.

[0370] When the foldable display terminal 1000 is folded, the ends of the first main body 301 and the second main body 302 of the foldable display terminal 1000 that are away from the pivot assembly 303 move closer to each other, thereby causing the display screen 200, which is fixed to the first main body 301 and the second main body 302, to fold. The rotation shaft 3032 of the pivot assembly 303 can rotate relative to the fixed shaft 3031, thereby causing the display screen 200 to bend. Furthermore, the rotation shaft 3032 of the pivot assembly 303 can rotate relative to the fixed shaft 3031, causing the edge protection structure 100 to bend, thus achieving synchronous bending of the edge protection structure 100 and the display screen 200. This ensures that the edge protection structure 100 always covers the edge of the bending area 2001 of the display screen 200, guaranteeing that the edge of the bending area 2001 of the display screen 200 is always well protected, regardless of the state of the foldable display terminal 1000. In this application, the flexible component 520 and the fixing plate 511 of the edge protection structure 100 both have good bending performance and will not significantly affect the bending state of the display screen 200. Instead, they can change shape accordingly with the bending state of the display screen 200. Therefore, when the display screen 200 of this embodiment is fully folded, the first fixing area 200a and the second fixing area 200b of the display screen 200 can fit together, and the pivot area 200c of the display screen 200 can bend naturally. In other words, this application provides an edge protection structure 100 in the foldable display terminal 1000, which can protect the edge of the bending area 2001 of the display screen 200 of the foldable display terminal 1000, improve the appearance of the foldable display terminal 1000, and not affect the folding of the display screen 200 or the reliability of the display screen 200. Please refer to [link to relevant documentation]. Figures 76-78 , Figure 76 The image shown is a replacement for the edge protection structure 100 of this application. Figure 1 After the edge protection structure 100 shown, the foldable display terminal 1000 is Figure 1 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 in the flattened state shown. Figure 77 The image shown is a replacement for the edge protection structure 100 of this application. Figure 1 After the edge protection structure 100 shown, the foldable display terminal 1000 is Figure 2 The diagram shows the structural state of the display screen 200 and edge protection structure 100 of the foldable display terminal 1000 when folded to the middle state. Figure 78 The image shown is a replacement for the edge protection structure 100 of this application. Figure 1 After the edge protection structure 100 shown, the foldable display terminal 1000 is Figure 3A structural state diagram of the display screen 200 and the edge protection structure 100 of the folding display terminal 1000 when folded to a fully closed state is shown in FIG. 1C.

[0371] In some embodiments of the present application, the surface of the edge protection structure 100 can also be coated with a plating layer to improve the appearance of the edge protection structure 100. For example, in some embodiments, the surface of the edge protection structure 100 or the surface of the flexible piece 520 of the edge protection structure 100 is coated with a plating layer, so that the edge protection structure 100 or the flexible piece 520 of the edge protection structure 100 can have the same color as the back cover of the folding display terminal 1000, thereby making the appearance color of the folding display terminal 1000 uniform and having a better appearance effect. In some embodiments, the plating layer can also block water, oxygen and other external factors from corroding the edge protection structure 100, thereby improving the quality of the folding display terminal 1000.

[0372] In the present application, the plating layer can be formed by evaporation through an evaporation process, or can be formed by deposition through a vapor deposition method, and the formation method of the plating layer is not specifically limited herein.

[0373] In some embodiments of the present application, the surface of the fixed plate 511 has a high degree of smoothness. When the edge protection structure 100 is mounted on the folding display terminal 1000, the fixed plate 511 of the edge protection structure 100 is stacked on the display screen 200 and contacts the edge of the display screen 200. In the embodiments of the present application, when the surface of the fixed plate 511 has a high degree of smoothness, the friction between the fixed plate 511 and the display screen 200 can be reduced, and the pulling between the fixed plate 511 and the display screen 200 due to friction during the bending process of the folding display terminal 1000 can be avoided, thereby ensuring the smoothness of the bending of the folding display terminal 1000 and avoiding damage to the display screen 200 caused by the pulling between the fixed plate 511 and the display screen 200, thereby improving the reliability of the folding display terminal 1000.

[0374] In some other embodiments of the folding display terminal 1000 of the present application, the surface of the fixed plate 511 away from the flexible piece 520 can also be stacked with a smooth layer, and the surface of the smooth layer can have a degree of smoothness greater than that of the surface of the fixed plate 511. In the embodiments of the present application, when the folding display terminal 1000 is mounted on the folding display terminal 1000, the smooth layer contacts the display screen 200. Since the smooth layer has a smooth surface, the friction between the smooth layer and the display screen 200 can be reduced, and the pulling between the smooth layer and the display screen 200 due to friction during the bending process of the folding display terminal 1000 can be avoided, thereby ensuring the smoothness of the bending of the folding display terminal 1000 and avoiding damage to the display screen 200 caused by the pulling between the smooth layer and the display screen 200, thereby improving the reliability of the folding display terminal 1000.

[0375] Please refer to it again. Figure 69 In some embodiments of this application, the width of the flexible member 520 is larger than the width of the fixed plate 511. The width direction of the flexible member 520 and the width direction of the fixed block 512 are both the same as the extension directions of the fixed shaft 3031 and the rotating shaft 3032 in this embodiment. Figure 69 In the Y-axis direction. In this embodiment, since the width of the flexible member 520 is larger than the width of the fixed plate 511, when the flexible member 520 is fixed to the fixed plate 511, the edge of the flexible member 520 in the width direction will extend beyond the edge of the fixed plate 511. Therefore, when the edge protection structure 100 is impacted, the impact force will act on the flexible member 520. Since the flexible member 520 is a more flexible structure than the fixed plate 511, it can better buffer the impact force, thereby preventing the impact force from acting on the fixed plate 511, and thus preventing the impact force from being transmitted to the display screen 200 through the fixed plate 511 and damaging the display screen 200.

[0376] Please see Figure 73 and Figure 75 In some embodiments of this application, when the edge protection structure 100 is installed on the foldable display terminal 1000, the second surface 522 of the flexible member 520 is coplanar with the surface of the first edge protection member 101 or the second edge protection member 102 away from the surface of the display screen 200, thereby enabling the foldable display terminal 1000 to have a flatter outer surface and improving the appearance of the foldable display terminal 1000.

[0377] In this application, by covering the edge of the bending area 2001 of the display screen 200 with the fixing plate 511 of the fixing member 510 and the flexible member 520 of the edge protection structure 100, the bending area 2001 of the display screen 200 can be prevented from being exposed, thereby improving the appearance of the foldable display terminal 1000. Furthermore, by covering the edge of the bending area 2001 of the display screen 200 with the flexible member 520 and the fixing plate 511 of the elastic sheet 310 of the edge protection structure 100, the edge of the bending area 2001 of the display screen 200 can be protected, preventing damage to the edge of the bending area 2001 from impacts, thus improving the reliability of the foldable display terminal 1000.

[0378] The above are preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
