Referring to fig. 1 to 3, fig. 1is a schematic structural diagram of an electronic device 10 according to an embodiment of the application, fig. 2 is a schematic structural diagram of a flexible display assembly 200 in fig. 1, and fig. 3 is another schematic structural diagram of the flexible display assembly 200 in fig. 2.

The electronic device 10 provided in the embodiment of the present application may be a mobile phone, a tablet computer, an intelligent bracelet, and the like, and the following description will only use the electronic device 10 as a mobile phone. As shown in fig. 1, the electronic device 10 may include: the housing assembly 100 and the flexible display assembly 200. The housing assembly 100 may be connected to the flexible display assembly 200, and both may enclose an accommodating space formed therein to accommodate various electronic devices required by the electronic apparatus 10. Meanwhile, both the housing assembly 100 and the flexible display assembly 200 may have flexibility such that both may be bent to change the form of the electronic device 10. In this embodiment, the flexible display assembly 200 may drive the housing assembly 100 to bend for multiple times, so that the electronic device 10 can have multiple different usage modes, so that a user can select a suitable mode to use the electronic device 10 according to his own needs, and the playability of the electronic device 10 is improved.

The case assembly 100 may be used to protect the flexible display assembly 200, and the case assembly 100 may also have flexibility in order not to affect bending of the flexible display assembly 200. For example, the housing assembly 100 may be made of flexible materials such as leather, rubber, silicone, and soft plastic, so that the housing assembly 100 may have flexibility to bend with bending of the flexible display assembly 200. Alternatively, the housing assembly 100 may be split into a plurality of sub-housings, and the plurality of sub-housings are connected by a hinge, so that the housing assembly 100 is folded by rotating the plurality of sub-housings. The material of the plurality of sub-shells can be metal, plastic, glass or ceramic and other hard materials. Furthermore, the housing assembly 100 may not be limited to designs employing the two approaches described above, which are merely exemplary illustrations of the housing assembly 100. In some embodiments, the housing assembly 100 may be designed in other ways, and the housing assembly 100 is only required to have flexibility, which is not limited in this embodiment.

The flexible display assembly 200 may be used to provide image display functionality, and the flexible display assembly 200 may be bent multiple times to provide a variety of different use configurations so that a user may select an appropriate configuration for use of the flexible display assembly 200 in different scenarios. As shown in fig. 2 to 3, the flexible display assembly 200 may include: flexible screen 210 and chain structure 220. Wherein the flexible screen 210 may be connected to the chain structure 220 and the chain structure 200 may be located on a non-display side of the flexible screen 210. Meanwhile, the chain structure 220 can support the flexible screen 210 to assist the flexible screen 210 to flatten, and the chain structure 220 can also drive the flexible screen 210 to bend for a plurality of times so as to fully exert the flexibility of the flexible screen 210, so that the flexible screen 210 can have a plurality of different use forms, and a user can conveniently select a proper form to use the flexible screen 210 according to the self requirement.

In particular, the flexible screen 210 may be an OLED (Organic Light-Emitting Diode) display screen, which may have flexibility. Meanwhile, the flexible screen 210 may include a protective film layer, a touch layer, and a display layer, which are sequentially stacked. The protective film layer is mainly used for protecting the display layer, and can be used as an outer surface of the electronic device 10, and can be made of flexible materials such as Polyimide (PI), colorless Polyimide (Colorless Polyimide, CPI) and the like, so as to improve the flexibility of the flexible screen 210. The touch layer may be disposed between the protective film layer and the display layer, and may be used to respond to a touch operation by a user on the protective film layer, so that the electronic device 10 can respond to the touch operation by the user. The display layer is mainly used for displaying pictures and can be used as an interactive interface for indicating a user to perform the touch operation on the protective film layer. In this embodiment, the flexible screen 210 may be flattened or bent with the aid of the chain structure 220, so as to fully exert the flexibility of the flexible screen 210, so that the flexible screen 210 may have a plurality of different use modes, so that a user can select a suitable mode to use the flexible screen 210 according to his own needs.

For example, when the user is using the electronic device 10 normally, the chain structure 220 may be in a flattened state (as shown in FIG. 2), which may be used to support the flexible screen 210 for flattening, so that the user may observe the image displayed on the flexible screen 210. When the user needs to carry the electronic device 10, the chain structure 220 may be in a bending state (as shown in fig. 3), and the head and tail ends of the chain structure 220 may be connected and enclose to form the wearing space 201, so as to drive the flexible screen 210 to be in an annular bending arrangement, and the flexible screen 210 may be located at one side of the chain structure 220 away from the wearing space 201, so that the user may wear the flexible screen 210 on the wrist through the wearing space 201, and use the flexible screen 210 as an intelligent bracelet. So configured, the flexible screen 210 may have two use configurations, flattened and in a ring-shaped folded configuration, such that a user selects an appropriate configuration to use the flexible screen 210 according to his own needs.

It will be appreciated that the flexible screen 210 may have a variety of different configurations in addition to the two configurations shown in fig. 2 and 3. For example, only a partial area of the chain structure 220 may be bent, and the end-to-end ends of the chain structure 220 may not be connected, so that the flexible screen 210 may be U-shaped or L-shaped in shape. That is, the user can impart various different usage forms to the flexible screen 210 by controlling the bending area and the bending times of the chain structure 220, not only the aforementioned ring shape, U shape or L shape, so as to achieve the purpose of facilitating the user to use the flexible screen 210 in a proper form according to his own needs. The specific configuration of the chain structure 220 will be described below with respect to only two configurations of the flexible screen 210 shown in fig. 2 and 3, and other configurations that the flexible screen 210 may have are not specifically illustrated herein.

The chain structure 220 may be used to support the flexible screen 210 and to carry the flexible screen 210 to flatten or bend to impart a variety of different use configurations to the flexible screen 210. As shown in fig. 2-3, the chain structure 220 may include: a plurality of the movable members 221 are connected in sequence. Two adjacent movable members 221 may be inserted into each other, and the plurality of movable members 221 may be arranged in a line, so that the chain structure 220 may be in a flattened state to support the flexible screen 210 for flattening. Meanwhile, the two adjacent movable pieces 221 can also relatively rotate, so that the head end and the tail end of the chain structure 220 can be connected and enclosed to form a wearing space 201, and the flexible screen 210 is driven to be in annular bending arrangement. So set up, chain structure 220 not only can assist flexible screen 210 to flatten and buckle, can also give flexible screen 210 a plurality of different use forms for the user can select suitable form to use according to self demand.

All directional indications (such as up, down, left, right, front, back … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a particular gesture (as shown in the drawings), and if the particular gesture changes, the directional indication changes accordingly. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Referring to fig. 4 to 5, fig. 4 is a schematic diagram illustrating a connection structure of two adjacent movable members 221 in fig. 2, and fig. 5 is a schematic diagram illustrating a connection structure of two adjacent movable members 221 in fig. 3.

The two adjacent movable members 221 can rotate relatively, so that the chain structure 220 can be bent for a plurality of times to change the shape of the flexible screen 210. As shown in fig. 4 to 5, in order to provide a space for avoiding rotation between the adjacent two movable members 221, one of the adjacent two movable members 221 is provided with a first mating surface 2201, the other one is provided with a second mating surface 2202, and both the first mating surface 2201 and the second mating surface 2202 may be inclined surfaces (the length direction of the chain structure 220 in the flattened state is a horizontal direction). When the chain structure 220 is in the flattened state, the first mating surface 2201 and the second mating surface 2202 may be connected, and an included angle may be formed between the first mating surface 2201 and the second mating surface 2202, so that a gap may be formed between the first mating surface 2201 and the second mating surface 2202. When the chain structure 220 is in a bent state, the first mating surface 2201 and the second mating surface 2202 can be engaged with each other, such that the gap can provide clearance for rotation between adjacent movable members 221.

Specifically, when the chain structure 220 is in a flattened state, the first mating surface 2201 and the second mating surface 2202 meet, and a common edge 2203 may also be formed. When the chain structure 220 is converted from the flattened state to the bent state, the first mating surface 2201 can rotate with the common edge 2203 as an axial direction and toward a direction approaching to the second mating surface 2202, so as to be attached to the second mating surface 2202 after rotating, so that relative rotation between two adjacent movable members 221 can occur. So set up, not only can realize the buckling of chain structure 220 through the relative rotation between the adjacent movable part 221, can also improve the compactibility and the steadiness of chain structure 220 when being in the state of buckling through first mating surface 2201 and the laminating of second mating surface 2202 mutually, reduce chain structure 220 and receive the probability of external force influence inefficacy under the state of buckling.

Alternatively, the first mating surface 2201 and the second mating surface 2202 may also be mated when the chain structure 220 is in the flattened state, and an included angle may also be formed between the first mating surface 2201 and the second mating surface 2202 when the chain structure 220 is in the bent state. Or, when the chain structure 220 is in the flattened state and the bent state, an included angle is formed between the first mating surface 2201 and the second mating surface 2202, and only the first mating surface 2201 can rotate with the common edge 2203 as the axis direction, so that the two adjacent movable members 221 can rotate relatively.

The terms "first," "second," "third," and the like in this disclosure are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

Referring to fig. 6 to fig. 7 in combination with fig. 4 to fig. 5, fig. 6 is a schematic structural view of the movable member 221 in fig. 4, and fig. 7 is another schematic structural view of the movable member 221 in fig. 4.

Two adjacent movable pieces 221 can be inserted and connected, so that a plurality of movable pieces 221 can be inserted and connected in sequence to form a straight line. As shown in fig. 4 to 7, one of the two adjacent movable members 221 is provided with a plug portion 2211, and the other is provided with a slot 2212. Wherein, the insertion portion 2211 may be located on the first mating surface 2201, the insertion groove 2212 may be formed on the second mating surface 2202, and the insertion portion 2211 may be inserted into the insertion groove 2212. Meanwhile, when the chain structure 220 is converted from the flattened state to the bent state, the insertion portion 2211 can also slide in the slot 2212, and the sliding track of the insertion portion 2211 may be an arc in which the arc center overlaps the common edge 2203. That is, the insertion portion 2211 can also rotate with the common side 2203 as an axis direction, so as to drive the first mating surface 2201 to rotate with the common side 2203 as an axis direction and be attached to the second mating surface 2202, so that the two adjacent movable members 221 can rotate relatively, thereby flattening or bending the chain structure 220.

In order to avoid the insertion portion 2211 from being separated from the insertion slot 2212, one of the two adjacent movable members 221 is further provided with a rotating shaft 2213, and the other is further provided with a sliding groove 2214. As shown in fig. 4 to 7, the rotating shaft 2213 may be disposed on the insertion portion 2211, the sliding groove 2214 may be disposed on two inner side walls disposed in the slot 2212, and two opposite ends of the rotating shaft 2213 may be respectively disposed in the two sliding grooves 2214. The rotating shaft 2213 can be clamped with the inner wall of the sliding groove 2214 in the direction that the inserting portion 2211 is separated from the inserting groove 2212, so as to prevent the inserting portion 2211 from separating from the inserting groove 2212 when sliding in the inserting groove 2212, and improve the connection stability of two adjacent movable pieces 221. Meanwhile, when the chain structure 220 is changed from the flattened state to the bent state, the rotating shaft 2213 can also slide in the sliding groove 2214, and the sliding track of the rotating shaft 2213 can also be an arc with an arc center overlapped with the common side 2203. That is, the rotating shaft 2213 can also rotate with the common side 2203 as an axis direction, so as to drive the first mating surface 2201 to rotate with the common side 2203 as an axis direction and be attached to the second mating surface 2202, so that the two adjacent movable members 221 can rotate relatively, thereby flattening or bending the chain structure 220.

As shown in fig. 4, when the spindle 2213 is positioned in the first position in the slide groove 2214, the first mating surface 2201 and the second mating surface 2202 may be connected to form an included angle. At this time, the plurality of movable members 221 inserted in sequence, that is, the chain structure 220 may be in a flattened state. Meanwhile, in order to avoid the first mating surface 2201 rotating in a direction away from the second mating surface 2202 in the flattened state, the rotating shaft 2213 can be clamped with an inner wall of the sliding groove 2214, so that the first mating surface 2201 can only rotate in a direction close to the second mating surface 2202, thereby limiting the overall bending direction of the chain structure 220.

Alternatively, when the rotating shaft 2213 is located in the first position in the sliding groove 2214, it may not be engaged with the inner wall of the sliding groove 2214, so that the first mating surface 2201 can also rotate in a direction away from the second mating surface 2202. By means of the arrangement, the chain structure 220 can have two opposite bending directions in the flattened state, so that the chain structure 220 can assist the flexible screen 210 to bend in the two opposite directions, and therefore the bending variability of the flexible screen 210 is improved, and the bending performance of the flexible screen 210 is fully exerted.

As shown in fig. 5, when the rotating shaft 2213 slides in the sliding groove 2214 from the first position to the second position, the first mating surface 2201 and the second mating surface 2202 may be abutted. At this time, the plurality of movable members 221 inserted in sequence, that is, the chain structure 220, may be in a bent state, and enclose a wearing space 201. Meanwhile, the rotating shaft 2213 can be clamped with the other inner wall of the sliding groove 2214, so that the first mating surface 2201 cannot continue to rotate towards the direction approaching to the second mating surface 2202. The sliding travel of the rotating shaft 2213 in the sliding groove 2214 can correspond to the rotating travel between the two adjacent movable pieces 221, so that the rotating direction and the travel of the two adjacent movable pieces 221 can be limited by the rotating shaft 2213 and the sliding groove 2214.

Alternatively, when the rotating shaft 2213 is located in the second position in the sliding groove 2214, it may not be engaged with another inner wall of the sliding groove 2214. At this time, the first mating surface 2201 and the second mating surface 2202 are also abutted to restrict rotation between the adjacent two movable members 221. It will be appreciated that the first and second positions of the spindle 2213 shown in fig. 4-5 are but one of the embodiments that can be employed with the present application. In some embodiments, the first and second positions may be changed when the chain structure 220 needs to be changed to other configurations than the flattened and bent states shown in fig. 2 and 3, which is not limited in this embodiment.

In order to improve the convenience of assembly, the slide groove 2214 may also penetrate the movable member 221 in a direction perpendicular to the inner side wall of the insertion groove 2212 to form openings on opposite side surfaces of the movable member 221 connected to the second mating surface 2202. So set up, when assembling two adjacent movable pieces 221, can insert the grafting portion 2211 into the slot 2212 first, then insert the pivot 2213 into the slot 2214 and the slot 2212 from the opening formed by the slot 2214 on the movable piece 221, and wear to locate on the grafting portion 2211, thereby realizing the assembly of two adjacent movable pieces 221. The rotating shaft 2213 may be a pin.

Alternatively, the sliding groove 2214 may not penetrate the movable member 221, and the rotating shaft 2213 may be designed like a pin, so that the rotating shaft 2213 may retract and avoid under the pushing of the inner sidewall of the slot 2212 when the inserting portion 2211 is inserted into the slot 2212. After the insertion portion 2211 is inserted into the corresponding position, the rotating shaft 2213 can be extended and inserted into the sliding groove 2214 under the action of elastic force, so as to realize the assembly of two adjacent movable pieces 221. The specific structure and principle of the rotating shaft 2213 can be referred to the existing ear-generating needle, and the description of this embodiment is omitted here.

Referring to fig. 8 to fig. 9 in combination with fig. 3, fig. 8 is a schematic view of a part of the connection structure of the end-to-end ends of the chain structure 220 in fig. 3, and fig. 9 is a schematic view of another connection structure of the end-to-end ends of the chain structure 220 in fig. 8.

In order to enable the chain structure 220 to enclose the wearing space 201 in a bent state, so that a user wears the flexible screen 210 on a wrist, the front end and the rear end of the chain structure 220 can be detachably connected. As shown in fig. 3 and 8 to 9, one of the two movable members 221 of the chain structure 220 at the head end and the tail end is provided with a clamping groove 2001, and the other is provided with a clamping member 2002. The clamping piece 2002 can be inserted into the clamping groove 2001 and can be clamped with the inner wall of the clamping groove 2001 in the direction of exiting the clamping groove 2001, so that the head end and the tail end of the chain structure 220 are fixedly connected, and the chain structure 220 can be surrounded to form the wearing space 201. Meanwhile, the clamping piece 2002 can also be contracted to release the clamping state of the clamping piece 2002 and the inner wall of the clamping groove 2001, so that the clamping piece 2022 can be withdrawn from the clamping groove 2001 after being contracted, and the disassembly of the head end and the tail end of the chain structure 220 is realized.

For example, the clip 2002 may be a auricular needle, and the inner wall of the clip groove 2001 may be provided with a groove. When the clip 2002 is inserted into the clip groove 2001, the clip 2002 can be elastically deformed and contracted by the pressing force of the inner wall of the clip groove 2001. When the clamping piece 2002 is inserted into the clamping groove 2001 to the groove, the clamping piece 2002 can be reset and inserted into the groove under the action of the elastic force, so that the clamping piece 2002 and the inner wall of the clamping groove 2001 are clamped in the direction of exiting the clamping groove 2001. Accordingly, when the chain structure 220 needs to be disassembled, the user can additionally use the ear needle by pressing, poking or pulling, that is, the clamping piece 2002 contracts, so that the clamping piece 2002 can withdraw from the groove, and the clamping state with the inner wall of the clamping groove 2001 is released, so that the end-to-end two ends of the chain structure 220 can be disassembled. The specific structure and principle of the clip 2002 can be referred to the existing ear acupuncture needle and will not be described herein.

Further, in order to improve the compactness of the chain structure 220 after the movable members 221 at the front and rear ends are connected, the clamping member 2002 can also slide in the clamping groove 2001, so that the movable members 221 at the front and rear ends can be attached to each other. As shown in fig. 8 to 9, one of the two movable members 221 at the leading end and the trailing end is provided with a third mating surface 2003, and the other is provided with a fourth mating surface 2004. The clamping groove 2001 is formed in the third mating surface 2003, and the clamping member 2002 is formed in the fourth mating surface 2004. When the clip 2002 is inserted into the clip groove 2001, the third mating surface 2003 and the fourth mating surface 2004 may be in a separated state. When the clamping member 2002 is inserted into the clamping groove 2001 and slid to a predetermined position, the third mating surface 2003 and the fourth mating surface 2004 can be attached to each other, so as to maintain the compactness of the structure after the two movable members 221 at the front and rear ends are connected. Of course, in some embodiments, the design of the third mating surface 2003 and the fourth mating surface 2004 may be omitted, and only the clamping member 2002 needs to be inserted into the clamping slot 2001 for clamping, so as to achieve detachable connection of the front end and the rear end of the chain structure 220.

To lock the flexible screen 210 when the flexible screen 210 is flattened to maintain the flattened state of the flexible screen 210 for user use, the flexible screen 210 may also be provided with a connector 211 that mates with the chain structure 220. As shown in fig. 10 to 12, the connecting member 211 may be sleeved on the plurality of movable members 221 of the chain structure 220, and the movable members 221 may rotate relative to the connecting member 211 when the chain structure 220 is in the flattened state. When the chain structure 220 is in a flattened state and the movable member 221 is not rotated relative to the connecting member 211, the rotation axis direction of the adjacent two movable members 221, that is, the extending direction of the common edge 2203, can be parallel to the flattened display surface of the flexible screen 210, so that when the adjacent two movable members 221 rotate, the flexible screen 210 can be bent under the driving of the movable member 221. When the chain structure 220 is in a flattened state, and the movable members 221 rotate relative to the connecting member 211, the extending direction of the common edge 2203 of two adjacent movable members 221 may intersect the flattened display surface of the flexible screen 210, so that the bending direction of the flexible screen 210 is not matched with the bending direction of the chain structure 220, and the flattened flexible screen 210 is locked by using the rotated chain structure 220, so that the user uses the flexible screen 210. In this embodiment, the number of the connecting pieces 211 may be multiple, and the number of the connecting pieces may be the same as the number of the movable pieces 221, and one connecting piece 211 may be sleeved on one movable piece 221 only, that is, the connecting pieces 211 and the movable pieces 221 are in one-to-one correspondence, so that the plurality of movable pieces 221 may drive the flexible screen 210 to bend through the connecting pieces 211.

As shown in fig. 11 to 12, in order to limit the rotation of the movable member 221 relative to the connecting member 211, a mating member 212 is further disposed on a side of the connecting member 211 facing the flexible screen 210, and a first limiting member 2215 and a second limiting member 2216 are further disposed on the movable member 221. When the chain structure 220 is in a flattened state and does not rotate relative to the connecting element 211, the engaging element 212 may be disposed opposite to the first limiting element 2215 and may generate a magnetic force that is attracted to the first limiting element 2215, so as to limit the rotation of the movable element 221 by using the magnetic force. When the chain structure 220 is in a flattened state and rotates relative to the connecting member 221, the engaging member 212 can be disposed opposite to the second limiting member 2216 and can generate a magnetic force absorbed by the second limiting member 2216 so as to control the rotation of the moving member 221 by using magnetic force lines. By the arrangement, the rotation of the chain structure 220 can be limited, and the probability of locking failure of the flexible screen 210 caused by the rotation of the chain structure 220 under the action of external force is reduced. In this embodiment, the mating member 212, the first limiting member 2215 and the second limiting member 2216 may be magnets. Alternatively, the mating member 212 may be a magnet, and the first and second limiting members 2215 and 2216 are objects that can be attracted by magnetic force, such as metal, etc. Alternatively still, the first and second stoppers 2215 and 2216 may be magnets, and the mating member 212 may be an object that can be attracted by a magnetic force. In this embodiment, the engaging member 212 may be disposed opposite to the second limiting member 2216 after the movable member 221 is rotated 90 ° relative to the connecting member 211.

Alternatively, in some embodiments, besides using a magnet to generate a magnetic force to limit the rotation of the movable member 221, a mechanical structure may be used to limit the rotation of the movable member 221, for example, a corresponding stop position and a telescopic engaging member may be provided, which only needs to limit the rotation of the movable member 221. Alternatively, in some embodiments, the chain structure may not be limited to be used for assisting bending or flattening of the flexible screen, but may be used for other structural members that need to be bent or flattened, for example, the chain structure may also be used on the housing assembly 100 to assist bending or flattening of the housing assembly 100, which is not limited in this embodiment.

In the chain structure 200 provided by the embodiment of the application, by arranging the plurality of movable pieces 221 which are inserted in sequence, one of the two adjacent movable pieces 221 is provided with the sliding groove 2214, the other is provided with the rotating shaft 2213 which is inserted in the sliding groove 2214 and can slide in the sliding groove 2214, the first matching surface 2201 of one of the two adjacent movable pieces 221 can be connected with the second matching surface 2202 of the other to form the common side 2203, and when the rotating shaft 2213 slides in the sliding groove 2214, the first matching surface 2201 can rotate relative to the second matching surface 2202 by taking the common side 2203 as the axial direction, so that the two adjacent movable pieces 221 can rotate relatively. When the flexible screen 210 is connected with the movable pieces 221 of the chain structure 220, the flexible screen 210 can be bent for a plurality of times under the driving of the movable pieces 221, so that the flexibility of the flexible screen 210 is fully exerted, and more using forms are given to the flexible screen 210.

The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent processes using the descriptions and the drawings of the present application or directly or indirectly applied to other related technical fields are included in the scope of the present application.
