In the second state, the fixing portion 100, the first chain 200 and the second chain 300 are connected end to form a sleeved space. When the support assembly 20 is used to support the flexible display panel 10 to form a display device, a user can sleeve the display device on the wrist through the sleeve space. Therefore, the support assembly 20 provided by the embodiment of the application not only can realize large-screen display of the display device, but also can enable the display device to be folded and wound on the wrist.

There are various ways in which the first chain 200 and the second chain 300 can move relative to each other, and in some alternative embodiments, the first chain 200 and the second chain 300 are stacked, and the second chain 300 is movably disposed relative to the first chain 200 along the extending direction of the chain assembly, so that the second chain 300 can move to an end of the second chain 300 facing away from the fixing portion 100, and the second chain 300 can be connected between the first end 110 of the fixing portion 100 and the first chain 200. Alternatively, both the first chain 200 and the second chain 300 may be bent to be able to change the shape of the sheathing space.

Alternatively, the first chain 200 has oppositely disposed third and fourth ends 200a, 200b, and the second chain 300 has oppositely disposed fifth and sixth ends 300a, 300b. In the first state, the third end 200a and the sixth end 300b are connected to the second end 120. During the transition from the first state to the second state, the second chain 300 moves relative to the first chain 200, the sixth end 300b moves along the first chain 200 to the fourth end 200b, and the fifth end 300a moves out and is able to interconnect with the first end 110. Thus, in the second state, the sixth end 300b is connected to the fourth end 200b and the fifth end 300a is connected to the first end 110. The second chain 300 is connected between the fixing portion 100 and the second chain 300 and encloses a housing space.

Optionally, the third end 200a is rotatably connected to the second end 120. In the second state, the sixth end 300b is rotatably connected to the fourth end 200b to enable changing the shape of the nesting space.

In these alternative embodiments, first chain 200 may be folded when adjacent two first links 210 are rotated, so that first chain 200 may better fit around the wrist of a user, etc.

Alternatively, the extension dimension of the first link 210 in the second direction Y is equal to the extension dimension of the fixing portion 100, so that the first chain 200 and the fixing portion 100 have the same width, and the first chain 200 and the fixing portion 100 can provide better support to the flexible display panel 10.

With continued reference to fig. 3, in some alternative embodiments, second chain 300 includes a plurality of second links 310, and plurality of second links 310 are disposed side-by-side in an extending direction of second chain 300 and rotatably coupled to one another such that second chain 300 is flexibly deformable relative to first direction X. In the first state, second chain 300 extends in first direction X, fifth end 300a and sixth end 300b are oppositely disposed in first direction X, and a plurality of second links 310 are disposed side-by-side in first direction X.

In these alternative embodiments, second chain 300 may be configured to bend as adjacent two second links 310 rotate, allowing second chain 300 to better fit around the wrist of a user, etc.

Alternatively, the extension dimension of second link 310 in second direction Y is equal to the extension dimension of fixed portion 100, so that second chain 300 and fixed portion 100 have the same width, and second chain 300 can be stably connected to second end 120.

Optionally, an extension dimension of second link 310 in second direction Y is equal to an extension dimension of first link 210 in second direction Y, i.e., second chain 300 and first chain 200 are disposed at the same width. In the second state, when the wrist and other parts of the user are sleeved in the sleeved space, the first chain 200 and the second chain 300 are arranged with the same width, so that more edges and corners can be prevented from being generated, and the comfort level of the user can be improved.

Alternatively, in the first state, the extension dimension of the first chain 200 and the second chain 300 in the thickness direction Z is equal to the extension dimension of the fixing portion 100, so that it is possible to ensure that the non-display side surface of the support assembly 20 is smoother.

Referring to fig. 7, fig. 7 is a schematic view of a partial enlarged structure of a support assembly 20 according to an embodiment of the application.

In some alternative embodiments, as shown in fig. 7, a magnetic attraction assembly is disposed on the second chain link 310, and at least two adjacent second chain links 310 are disposed in a mutually attracted manner by the magnetic attraction assembly. By providing a magnetic attraction assembly, the second chain 310 is enabled to secure a straightened state in the first state. The second chain 300 in a straightened state provides support for the first chain 200, so that the problem that the first chain 200 is easy to bend in the first state can be solved, the supporting surface formed by the first chain 200 and the fixing portion 100 is smoother, and better support can be provided for the flexible display panel 10.

Alternatively, the magnetic attraction assembly includes a first magnetic attraction portion 320 and a second magnetic attraction portion 330 that are opposite in polarity and are disposed side by side along the extending direction of the second chain 300.

Alternatively, when the plurality of second links 310 are arranged side by side, the first magnetic attraction portion 320 of one of the adjacent two second links 310 and the second magnetic attraction portion 330 of the other are arranged adjacent, and in the first state, the adjacent two second links 310 are attracted to each other by the first magnetic attraction portion 320 and the second magnetic attraction portion 330. As shown in fig. 7, the second chain 300 extends in the first direction X, which is the extending direction of the second chain 300, and thus the first magnetic attraction portions 320 and the second magnetic attraction portions 330 are disposed side by side in the first direction X.

In these alternative embodiments, in the first state, when two adjacent second links 310 are attracted to each other by the first magnetic attraction portions 320 and the second magnetic attraction portions 330, the second chain 300 is kept in a straightened state. The second chain 300 in a straightened state provides support for the first chain 200, so that the problem that the first chain 200 is easy to bend in the first state can be solved, the supporting surface formed by the first chain 200 and the fixing portion 100 is smoother, and better support can be provided for the flexible display panel 10.

Optionally, two sets of first magnetic attraction portions 320 and second magnetic attraction portions 330 are disposed on the second link 310, and the two sets of first magnetic attraction portions 320 and second magnetic attraction portions 330 are distributed at intervals along the width direction of the second chain 300. The second chain 300 has two sets of first and second magnetic attraction portions 320 and 330 spaced apart along the second direction Y on the second link 310, so that different portions of the second link 310 in the second direction Y can be attracted to adjacent second links 310.

Referring to fig. 7 and fig. 8 together, fig. 8 is a schematic structural diagram of part of a supporting assembly 20 according to an embodiment of the application. For better illustration of the structure of the support assembly 20 of the present application, a non-display side structural schematic of the support assembly 20 is shown in fig. 8, and the first chain 200 is not shown in fig. 8.

In some alternative embodiments, as shown in fig. 7 and 8, a third magnetic attraction portion 340 is provided on at least one of the first chain 200 and the second chain 300, and in the first state, the second chain 300 is attracted to the first chain 200 by the third magnetic attraction portion 340. The stability of the relative positions of the first chain 200 and the second chain 300 in the first state is ensured.

Alternatively, as shown in fig. 7 and 8, when the third magnetic attraction portion 340 is disposed on the second chain 300 and the first magnetic attraction portion 320 and the second magnetic attraction portion 330 are further disposed on the second chain 300, the third magnetic attraction portion 340 is located at a side of the first magnetic attraction portion 320 and the second magnetic attraction portion 330 facing the first chain 200. In these alternative embodiments, on the one hand, the distance between the third magnetic attraction portion 340 and the first chain 200 can be reduced, and the stability of the relative positions of the first chain 200 and the second chain 300 can be ensured. On the other hand, the influence of the third magnetic attraction portion 340 on the first magnetic attraction portion 320 and the second magnetic attraction portion 330 can be improved.

Alternatively, the third magnetic attraction portion 340 is an electromagnetic component, and in the first state, the third magnetic attraction portion 340 is energized to generate magnetic attraction force, so that the first chain 200 and the second chain 300 are attracted to each other by the magnetic component. In the second state, the third magnetic attraction portion 340 is powered off to generate no magnetic attraction force, so that the user can conveniently restore the second chain 300 in the first state to the first state with respect to the first chain 200.

Alternatively, the first magnetic attraction portion 320 and the second magnetic attraction portion 330 are electromagnetic components, and in the first state, the first magnetic attraction portion 320 and the second magnetic attraction portion 330 are electrified and attracted to each other, so that two adjacent second chain links 310 are attracted to each other through the first magnetic attraction portion 320 and the second magnetic attraction portion 330, and the second chain 300 is in a straight state. In the second state, the first magnetic attraction portion 320 and the second magnetic attraction portion 330 are powered off to generate no magnetic attraction force, and the second chain 300 can be bent and deformed.

Referring to fig. 7 to 9, fig. 9 is a schematic diagram of a partial enlarged structure of fig. 4.

In some alternative embodiments, as shown in fig. 7-9, a first spacing gap 220 is formed between two adjacent first links 210, and in the first state, at least a portion of second links 310 are positioned in first spacing gap 220, which, on the one hand, reduces the overall thickness of first chain 200 and second chain 300, reducing the thickness dimension of support assembly 20. On the other hand, when at least part of the second links 310 fills the first limiting gap 220, it is also possible to avoid that two adjacent first links 210 change their relative positions through the first limiting gap 220, which results in bending of the first chain 200, and improve the stability of the first chain 200 structure in the first state. Limiting at least part of second link 310 to first limiting gap 220 also increases the contact area between first chain 200 and second chain 300, ensuring stability of the relative positions of first chain 200 and second chain 300.

In some alternative embodiments, referring to fig. 7 and 9, first link 210 includes a first top surface 211 facing away from second chain 300 and a first bottom surface 212 facing toward second chain 300, and a first side surface 213 connecting first top surface 211 and first bottom surface 212, first top surface 211 having a larger dimension than first bottom surface 212 to form a first spacing gap 220 between adjacent two first links 210, at least a portion of second links 310 being inserted into first spacing gap 220.

In these alternative embodiments, the first top surface 211 is used to provide support to the flexible display panel 10 when the support assembly 20 is used to support the flexible display panel 10. The first top surfaces 211 have a larger size, which can reduce the space between the first top surfaces 211 of adjacent two first links 210, reduce the gap of the supporting surface, and enable the first top surfaces 211 to provide better support to the flexible display panel 10. The first limiting gap 220 is located between the adjacent two first side surfaces 213, so that the adjacent two first links 210 can mutually rotate around the connection between the first top surface 211 and the first side surfaces 213, and bending deformation of the first chain 200 is realized by changing the size of the first limiting gap 220.

In some alternative embodiments, referring still to fig. 7 and 9, in the first state, the spacing between two adjacent first links 210 increases gradually in the direction from first top surface 211 to first bottom surface 212, i.e., first side edges 213 are disposed obliquely, and the spacing between two oppositely disposed first side edges 213 increases gradually in the direction from first top surface 211 to first bottom surface 212, so as to form first spacing gap 220 between two oppositely disposed first side edges 213. The two first side surfaces 213 disposed opposite to each other refer to two first side surfaces 213 disposed adjacent to the two first links 210 and disposed adjacent to each other to form the first limiting gap 220.

In these alternative embodiments, the spacing between the two opposite first side surfaces 213 increases gradually along the direction from the first top surface 211 to the first bottom surface 212, so that the first limiting gap 220 has a larger opening size, so that the second chain 300 is convenient to be inserted into the first limiting gap 220.

With continued reference to fig. 7 and 9, in some alternative embodiments, the second link 310 includes a first portion 311 and a second portion 312 located on a side of the first portion 311 facing the first chain 200, where in the first state, the second portion 312 is inserted into the first limiting gap 220.

Optionally, the first part 311 and the second part 312 are integrally formed, so as to improve the stability of the relative positions of the first part 311 and the second part 312.

Alternatively, when the third magnetic attraction portion 340 for attracting the first chain 200 is provided on the second chain 300, the third magnetic attraction portion 340 is provided at the second sub portion 312 to reduce the interval between the third magnetic attraction portion 340 and the first chain 200. Optionally, the third magnetic attraction portion 340 is located at an end of the second sub portion 312 facing the first chain 200, so that in the first state, the third magnetic attraction portion 340 can extend into the first limiting gap 220 and attract the two first links 210 located at two sides thereof in the first direction X, so as to ensure stability of a relative position between the first chain 200 and the second chain 300.

Alternatively, with continued reference to fig. 7 and 9, the first portions 311 of two adjacent second links 310 are rotatably connected to each other, and the extension dimension of the first portions 311 is larger than the extension dimension of the second portions 312 in the first direction X. The second portion 312 is configured to be inserted into the second limiting gap 350, and the first portion 311 is configured to implement rotational connection between two adjacent second links 310. In the first direction X, when the extension dimension of the first portion 311 is greater than the extension dimension of the second portion 312, the spacing between the first portions 311 of the adjacent second links 310 is smaller, so as to ensure the stability of the relative position between the adjacent two second links 310.

Optionally, in the first state, referring to fig. 7 and 9, at least a portion of the first portion 311 abuts against the first bottom surface 212 to reduce the distance between the first chain 200 and the second chain 300, reduce the overall thickness of the support assembly 20, increase the contact area between the first chain 200 and the second chain 300, and ensure the stability of the relative positions of the first chain 200 and the second chain 300.

Alternatively, referring to fig. 7 and 9, the first magnetic attraction portion 320 and the second magnetic attraction portion 330 are disposed on the first sub portion 311. The two adjacent second chain links 310 are rotatably connected with each other through the first subsection 311, and the distance between the first subsections 311 of the two adjacent second chain links 310 is smaller, and the first magnetic attraction part 320 and the second magnetic attraction part 330 are arranged on the first subsection 311, so that enough magnetic attraction force between the two adjacent second chain links 310 can be ensured.

Alternatively, in the first state, the first sections 311 have two abutment surfaces disposed opposite to each other in the first direction X, and the adjacent two first sections 311 are in abutting connection with each other through the abutment surfaces. In the same first subsection 311, the first magnetic attraction portion 320 is arranged close to one of the abutting surfaces, the second magnetic attraction portion 330 is arranged close to the other abutting surface, and the two abutting surfaces are mutually abutted by the magnetic attraction force generated between the first magnetic attraction portion 320 and the second magnetic attraction portion 330 of the two adjacent first subsections 311.

Optionally, referring to fig. 7 and 8, second spacing gap 350 is provided between second portions 312 of two adjacent second links 310, and in the first state, at least a portion of first links 210 are inserted into second spacing gap 350. The first chain 200 and the second chain 300 are inserted into each other, so that the contact area of the first chain 200 and the second chain 300 can be increased, and the stability of the relative positions of the first chain 200 and the second chain 300 is ensured.

In some alternative embodiments, referring to fig. 7 and 9, the first side 213 includes a limiting step, the limiting step includes a limiting surface 213a disposed parallel to the first top 211, and the second portion 312 is limited to a side of the limiting surface 213a facing away from the first top 211.

In these alternative embodiments, the limiting surface 213a can provide a limit to the second portion 312 on one hand, so as to avoid the second portion 312 from being inserted too deeply into the second limiting gap 350 to cause the spacing between two adjacent first links 210 to increase, which affects the support of the flexible display panel 10 by the first chain 200. The limiting surface 213a can increase the contact area between the first chain 200 and the second chain 300, and ensure the stability of the relative positions of the first chain 200 and the second chain 300.

There are various ways in which two adjacent first links 210 are rotatably connected to each other, and in some alternative embodiments, a first limiting groove is provided on a surface of at least one of the two adjacent first links 210 facing the other, and a first rotating member 230 is provided in the first limiting groove, so that the two adjacent first links 210 are rotatably connected to each other by the first rotating member 230.

Optionally, in two adjacent first chain links 210, a first limiting groove is disposed on a surface of one of the two adjacent first chain links facing the other, and the two first limiting grooves enclose a first space for limiting the first rotating member 230, and the first rotating member 230 is rotatably connected with the first chain links 210 in the first limiting groove. For example, two first through holes extending along the second direction Y and arranged side by side along the first direction X are disposed in the first rotating member 230, two opposite inner wall surfaces of the first limiting groove in the second direction Y are provided with first grooves, the first rotating shaft is disposed through the first through holes and limited in the two first grooves so that the first rotating member 230 is rotatably disposed relative to the first chain links 210, and two first rotating shafts can be disposed on the first rotating member 230 in a penetrating manner and cooperate with the two first chain links 210, so that two adjacent first chain links 210 can be rotatably connected through the two first rotating shafts on the first rotating member 230.

There are various ways in which two adjacent second links 310 are rotatably connected to each other, and in some alternative embodiments, a second limiting groove is provided on a surface of at least one of the two adjacent second links 310 facing the other, and a second rotating member 360 is provided in the second limiting groove, so that the two adjacent second links 310 are rotatably connected to each other by the second rotating member 360.

Optionally, in two adjacent second chain links 310, a second limiting groove is disposed on a surface of one of the two adjacent second chain links facing the other, and the two second limiting grooves enclose a second space for limiting the second rotating member 360, and the second rotating member 360 is rotatably connected with the second chain links 310 in the second limiting groove.

For example, two second through holes extending along the second direction Y and arranged side by side along the first direction X are arranged in the second rotating member 360, two opposite inner wall surfaces of the second limiting groove in the second direction Y are provided with second grooves, the second rotating shaft is arranged through the second through holes and limited in the two second grooves in a penetrating manner so that the second rotating member 360 can be rotatably arranged relative to the second chain links 310, and the second rotating member 360 can be provided with two second rotating shafts in a penetrating manner and is matched with the two second chain links 310, so that two adjacent second chain links 310 can be rotatably connected through the two second rotating shafts on the second rotating member 360.
