[0039] It is to be understood that the specific embodiments described herein are merely illustrative of the application and should not be used to limit the scope of the application.

[0040] In the following description, the suffixes used for elements such as "module", "part", or "unit" are used only to facilitate the description of the present application, and have no particular meaning by themselves. Thus, "module", "part", or "unit" can be mixedly used.

[0041] The folding screen device includes a folding screen and a hinge mechanism, the hinge mechanism includes a base and two swing arms rotationally connected with the base, and the folding screen is connected with the two swing arms on opposite sides respectively, and folding and unfolding of the folding screen are realized by rotation of the swing arms. When the folding screen is folded, due to a certain height difference between the base and the swing arms, the part of the folding screen corresponding to the base will move away from the base and bend, that is, the phenomenon of reverse bending, which affects the service life of the folding screen.

[0042] To solve the above technical problems, the embodiments of the present application provide a folding screen assembly and a folding screen device. The folding screen device includes a hinge mechanism, and the folding screen assembly includes a folding screen and a stop piece. The folding screen device includes a support layer and a display layer. The support layer is used to be connected with the hinge mechanism, and the display layer is arranged on the side of the support layer away from the hinge mechanism. The support layer includes a bending area and support areas arranged on the opposite sides of the bending area along a first direction. The bending area and the two support areas are on the same plane when the folding screen is unfolded, and the bending area bends when the folding screen is folded, so that the two support areas overlap.

[0043] However, when the folding screen switches from the unfolded state to the folded state, the bending area will move away from the hinge mechanism along a third direction first and then move towards the hinge mechanism and bend. The phenomenon that the bending area moves away from the hinge mechanism along the third direction first is the phenomenon of reverse bending. Frequent occurrence of the phenomenon of reverse bending will increase the bending frequency of the folding screen and affect the service life of the folding screen.

[0044] Therefore, the stop piece is arranged on the hinge mechanism, and the bending area extends out of the stop part along the second direction, so that the stop piece and the stop part abut in the third direction. In this way, when the bending area has a tendency to reverse, the stop piece applies a force in the opposite direction to the stop part to prevent the bending area from reversing, thereby effectively avoiding the occurrence of the phenomenon of reverse bending and being conducive to improving the service life of the folding screen.

[0045] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail in specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0046] It should be noted that the folding screen assembly provided by the embodiments of the present application can be applied to various different folding screen devices.

[0047] Referring to FIGS. 1 and 2, Figures 1 to 6 and Figures 9 to 11 As shown in FIGS. 1 and 2, the folding screen assembly provided by the embodiments of the present application is used in a folding screen device, and the folding screen device includes a hinge mechanism. The folding screen assembly includes: a folding screen 100 including a support layer 110 and a display layer 120, the support layer 110 being configured to be connected to the hinge mechanism, and the display layer 120 being arranged on a side of the support layer 110 away from the hinge mechanism; the support layer 110 including a bending region 111 and two support regions 112, the two support regions 112 being symmetrically arranged on opposite sides of the bending region 111 along a first direction, and the bending region 111 extending a stop portion 1111 along a second direction; and a stop piece 200 arranged on the hinge mechanism and abutting against the stop portion 1111 along a third direction, the first direction, the second direction and the third direction being perpendicular to each other.

[0048] It should be noted that, Figure 4 In the embodiments of the present application, the X direction is the first direction, the Y direction is the second direction, and the Z direction is the third direction.

[0049] In the embodiments of the present application, the folding screen device includes a hinge mechanism, and the hinge mechanism includes a base 10 and two swing arms 20, the two swing arms 20 being arranged on opposite sides of the base 10 along a first direction and being rotatably connected to the base 10. The folding screen assembly includes a folding screen 100 and a stop piece 200. The folding screen 100 includes a support layer 110 and a display layer 120, the display layer 120 being arranged on the support layer 110, the support layer 110 including a bending region 111 and support regions 112 arranged on opposite sides of the bending region 111 along the first direction, the two support regions 112 being correspondingly connected to the two swing arms 20, and the bending region being located above the base 10. When the folding screen 100 switches between the folded and unfolded states, the swing arms 20 and the support regions 112 rotate relative to the base 10 at the same time. The display layer 120 is arranged as a flexible display screen and can change with the change in the shape of the support layer 110. When the folding screen 100 is unfolded, the support regions 112 and the bending region 111 are located on the same plane. When the folding screen 100 is folded, the bending region is bent, and the two support regions 112 overlap.

[0050] However, due to the limitation of the assembly process, there is a certain height difference between the swing arms 20 and the base 10 that is difficult to eliminate. This results in that, when the folding screen 100 switches from the unfolded state to the folded state, the bending region 111 of the support layer 110 moves and bends away from the base 10 along the third direction first, and then moves and reversely bends toward the base 10 along the third direction to finally realize the folding of the folding screen 100.

[0051] The folding area 111 of the support layer 110 moves and bends away from the base 10 along the third direction, which is a reverse bending phenomenon. Frequent reverse bending phenomenon can increase the bending times and bending angle of the folding area 111, and increase the bending times of the display layer 120, thereby affecting the service life of the foldable screen 100 as a whole.

[0052] Optionally, a stop piece 200 is mounted on the base 10, and the folding area 111 extends out of a stop portion 1111 along the second direction. The stop portion 1111 is not covered by the display layer 120, and the stop piece 200 abuts against the stop portion 1111 along the third direction. When the folding area 111 has a reverse bending trend, the stop portion 1111 presses the stop piece 200 along the third direction, and the stop piece 200 applies pressure to the stop portion 1111 towards the base 10, thereby hindering the folding area 111 from moving away from the base 10. Thus, the possibility of reverse bending phenomenon can be reduced, thereby saving the bending times of the foldable screen 100 and improving the service life of the foldable screen 100.

[0053] Optionally, the stop piece 200 can be one on one side of the foldable screen 100 along the second direction, or two on opposite sides of the foldable screen 100 along the second direction. The folding area 111 extends out of a corresponding stop portion 1111 on each side along the second direction. Two stop pieces 200 are arranged correspondingly with the two stop portions 1111, thereby applying pressure to the support layer 110 from both sides to ensure the uniformity of the force applied to the folding area 111 and prevent the foldable screen 100 from reverse bending. The specific number and position of the stop piece 200 are not limited in the embodiments of the present application, as long as the stop piece 200 can hinder the folding area 111 from moving away from the base 10.

[0054] In some implementable manners, referring to FIGS. 1 to 5, Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 , the stop piece 200 of the present application includes a protection portion 210 and a shielding portion 220.

[0055] Optionally, the shielding portion 220 is connected with the protection portion 210. The protection portion 210 extends along the first direction, and the shielding portion 220 extends along the second direction.

[0056] Optionally, in the third direction, the display layer 120 is partially located between the shielding portion 220 and the hinge mechanism, and a gap is formed between the shielding portion 220 and the display layer 120.

[0057] In some embodiments, the length of the hinge mechanism in the second direction is greater than the length of the folding screen 100 in the second direction, which results in the connection structure between part of the hinge mechanism and the folding screen 100 being exposed, so the protection part 210 and the shielding part 220 are needed to cover the internal connection structure to avoid damage to the internal structure of the folding screen device while maintaining the aesthetics of the appearance of the folding screen device.

[0058] Optionally, the protection part 210 extends in the second direction and is located on one side of the folding screen 100 in the second direction, which is beneficial to avoid the bending area 111 from being impacted from the second direction. The shielding part 220 extends in the second direction, and part of the folding screen 100 in the third direction is located between the shielding part 220 and the hinge mechanism, so as to cover the stop part 1111 and other internal connection structures under the shielding part 220, which is beneficial to improve the aesthetics of the folding screen device.

[0059] Optionally, a certain gap needs to be left between the shielding part 220 and the display layer 120 to avoid interference of the stop piece 200 with the unfolding and folding of the folding screen 100.

[0060] In some implementable manners, referring to FIGS. 1 to 5, Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 , the stop piece 200 of the embodiment of the present application further includes a first limiting part 230.

[0061] The first limiting part 230 is arranged on the side of the shielding part 220 facing the display layer 120 in the third direction, and the first limiting part 230 abuts against the stop part 1111.

[0062] Optionally, the stop piece 200 abuts against the stop part 1111 in the third direction through the first limiting part 230, and the first limiting part 230 is fixed on the shielding part 220. When the folding screen 100 switches from unfolding to folding, the bending area 111 has a tendency to move away from the base 10, so that the stop part 1111 extrudes the first limiting part 230 in the third direction. The first limiting part 230 exerts a force in the opposite direction on the stop part 1111, thereby effectively hindering the movement of the bending area 111, which is beneficial to reduce the possibility of the occurrence of the reverse bending phenomenon, thereby playing a role in protecting the folding screen 100 and prolonging the service life of the folding screen 100.

[0063] Optionally, the first limiting portion 230 can be provided as an elastic member, when the stop portion 1111 extrudes the first limiting portion 230, the first limiting portion 230 generates a greater elastic force, thereby hindering the movement of the stop portion 1111, the first limiting portion 230 can also be provided as a flexible member with lower hardness, which can apply pressure to the stop portion 1111 while playing a certain buffering role, avoiding excessive pressure causing the bending area 111 to break, the specific structure and material of the first limiting portion are not limited in the embodiments of the application, and the first limiting portion can only apply a force to the stop portion 1111 towards the base 10.

[0064] Optionally, the width of the stop portion 1111 of the support layer 110 in the first direction can be slightly greater than the width of the first limiting portion 230 in the first direction, to ensure that the first limiting portion 230 can fully apply pressure to the stop portion 1111, and ensure the limiting effect of the stop member 200 on the folding screen 100.

[0065] In some implementable manners, as shown in Figure 1 , Figure 2 and Figure 4 , the first limiting portion 230 of the embodiment of the application is provided with an avoiding gap 231 on the side close to the display layer 120, to prevent the first limiting portion 230 from contacting the display layer 120.

[0066] Optionally, the avoiding gap 231 needs to be provided on the first limiting portion 230, to prevent the first limiting portion 230 from contacting the display layer 120 on the premise that the first limiting portion 230 can abut against the stop portion 1111, and to prevent friction between the first limiting portion 230 and the display layer 120 when the folding screen 100 is folded or unfolded, hindering the rotation of the folding screen 100 or damaging the display layer 120.

[0067] In some implementable manners, as shown in Figure 1 , Figure 3 and Figure 7 , the first limiting portion 230 of the embodiment of the application is a flexible member.

[0068] Optionally, the first limiting portion 230 can be provided as a flexible member, for example, the first limiting portion 230 is soft glue, so that when extrusion occurs between the first limiting portion 230 and the stop portion 1111, the first limiting portion 230 has a certain buffering effect when applying pressure to the stop portion 1111, avoiding the problem of the stop portion 1111 being pressed off, further protecting the folding screen 100 from damage and improving the service life of the folding screen 100.

[0069] In some implementable manners, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the stop piece 200 of the embodiment of the present application further comprises a plug-in part 240, which is connected with the protection part 210.

[0070] Optionally, the plug-in part 240 is used for plugging with the hinge mechanism.

[0071] Optionally, the plug-in part 240 is arranged on the stop piece 200, and the plug-in part 240 is connected with the protection part 210 and extends along the third direction. The plug-in part 240 is inserted into the mounting groove of the base 10 along the third direction, so as to fix the stop piece 200 on the base 10.

[0072] In some implementable manners, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the stop piece 200 of the embodiment of the present application further comprises two second limiting parts 250, which are connected with the protection part 210, and the second limiting parts 250 are used for limiting cooperation with the hinge mechanism.

[0073] In some embodiments, the second limiting part 250 is further arranged on the stop piece 200, and the second limiting part 250 is inserted into the limiting hole of the hinge mechanism along the third direction, so as to avoid the first limiting part 230 from being extruded by the stop part 1111 to cause the rotation or dislocation of the stop piece 200, and to facilitate the stability of the connection between the stop piece 200 and the hinge mechanism.

[0074] Referring to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 11 The embodiment of the present application further provides a folding screen device, which comprises a hinge mechanism and any folding screen assembly described above.

[0075] Optionally, the hinge mechanism can further comprise the base 10 and two swing arms 20, which are arranged on the two sides of the base 10 opposite along the first direction, and the swing arm 20 is rotationally connected with the base 10.

[0076] Optionally, the two swing arms 20 are correspondingly connected with the two support areas 112 of the support layer 110; and the stop piece 200 is arranged on the base 10.

[0077] Optionally, the structure and working principle of the folding screen assembly are described in detail in the above embodiments, which will not be repeated here.

[0078] In the embodiment of the present application, the two swing arms 20 are rotationally connected with the hinge mechanism, and the two swing arms 20 are correspondingly connected with the two support areas 112 of the support layer 110. When the folding screen 100 is switched between folding and unfolding, an external force is applied to the folding screen 100, so that the support areas 112 and the swing arms 20 are simultaneously rotated relative to the hinge mechanism. The bending area 111 of the support layer 110 is correspondingly arranged above the base 10. The stop piece 200 is fixed on the base 10, and the stop portion 1111 on the bending area 111 is located between the first limiting portion 230 of the stop piece 200 and the base 10 in the third direction. When the folding screen 100 is switched between folding and unfolding, the stop piece 200 can prevent the bending area 111 from being bent back, while not affecting the rotation of the swing arm 20, so as to ensure that the folding screen 100 can be smoothly rotated.

[0079] In some implementable manners, as shown in Figure 1 、 Figure 3 and Figure 4 , the base 10 of the embodiment of the present application sequentially arranges the protection area 11 and the connecting area in the second direction.

[0080] Optionally, the bending area 111 of the support layer 110 is arranged in the connecting area.

[0081] Optionally, the mounting groove is arranged on the protection area 11, and the insertion portion 240 of the stop piece 200 is inserted into the mounting groove.

[0082] Optionally, the length of the base 10 in the second direction is longer than the length of the folding screen 100 in the second direction. After the folding screen 100 is mounted on the hinge mechanism, the bending area 111 of the support layer 110 covers the connecting area of the base 10, and the protection area 11 is exposed. The mounting groove is arranged on the protection area 11, and the insertion portion 240 of the stop piece 200 is inserted into the mounting groove, so as to be fixed on the mounting base. In this way, the stop piece 200 can be provided with a certain mounting space, and interference of the stop piece 200 with folding and unfolding of the folding screen 100 can be avoided.

[0083] In some implementable manners, as shown in Figure 1 、 Figure 3 and Figure 4 , two limiting holes are arranged on the protection area 11 of the embodiment of the present application, and the second limiting portion 250 on the stop piece 200 is limitedly matched with the limiting holes.

[0084] Optionally, two limiting holes can be respectively arranged on two sides of the stop portion 1111 opposite in the first direction, and the second limiting portion 250 on the stop piece 200 is inserted into the limiting hole, and the second limiting portion 250 is matched with the shape of the limiting hole, wherein the second limiting portion 250 can be clamped with the limiting hole, or can be connected by other ways, and the specific connection manner is not limited in the embodiment of the application, and the stop piece 200 can be effectively prevented from being dislocated.

[0085] In summary, the folding screen assembly and the folding screen device provided by the embodiment of the application, the folding screen assembly and the hinge mechanism of the folding screen device, the hinge mechanism includes a base 10 and two swing arms 20, the two swing arms 20 are arranged on two sides of the base 10 opposite in the first direction and are rotationally connected with the base 10, the folding screen assembly includes a folding screen 100 and a stop piece 200, the folding screen 100 includes a support layer 110 and a display layer 120, the support layer 110 includes a bending area 111 and two support areas 112, the two support areas 112 are arranged on two sides of the bending area 111 opposite in the first direction, the two support areas 112 are correspondingly connected with the two swing arms 20, and the bending area 111 is correspondingly arranged above the base 10, and the display layer 120 is covered on a side of the support layer 110 away from the hinge mechanism.

[0086] Due to the limitation of the assembly process, there is a height difference between the swing arm 20 and the base 10 that is difficult to eliminate, thereby causing the bending area 111 to move away from the base 10 and appear a reverse bending phenomenon during the process of switching from unfolding to folding of the folding screen 100, and the frequent occurrence of the reverse bending phenomenon can affect the service life of the folding screen 100. Therefore, the stop piece 200 is arranged on the base 10, the bending area 111 extends the stop portion 1111 in the second direction, the stop portion 1111 is located between the stop piece 200 and the base 10 in the third direction, and the stop portion 1111 abuts against the stop piece 200.

[0087] In this way, when the folding screen 100 is switched from unfolding to folding, the stop portion 1111 has a tendency to move away from the base 10, thereby causing the stop portion 1111 to press the stop piece 200, the stop piece 200 applies a force to the stop portion 1111 towards the base 10, thereby hindering the bending area 111 from appearing a reverse bending phenomenon, thereby effectively reducing the number of times of reverse bending of the folding screen 100, and being conducive to improving the service life of the folding screen device.
