The embodiment of the present application mainly describes the hinge assembly 1 as being connected to the first support 4 and the second support 5 through a sliding combination, and those skilled in the art can easily think that the hinge assembly 1 is connected to the first support 4 and the third support 6 through a sliding combination through the description of the embodiment of the present application, so that detailed description of the connection of the first support 4, the hinge assembly 1 and the third support 6 is omitted.

Still alternatively, the hinge assembly 1 may include a slide rail, the first sliding assembly 2 includes a slide groove, and the slide rail of the hinge assembly 1 is disposed in the slide groove of the first sliding assembly 2 and slidably connected to the first sliding assembly 2.

Referring to fig. 9 and 10, fig. 9 is an exploded schematic view of a sliding mechanism according to an embodiment of the present application. Fig. 10 is an enlarged partial schematic view of a dashed line region of one of the slide mechanisms provided in fig. 9. The first sliding component 2 is provided with a first sliding chute 21. Alternatively, the first slide groove 21 is a slide groove extending in the Y-axis direction. Specifically, both ends of the first sliding slot 21 are open.

Referring to fig. 9 and 10, in an embodiment, the second sliding assembly 3 is slidably connected to the hinge assembly 1 along the Y-axis direction. Alternatively, the second slider assembly 3 may be directly slidably coupled to the hinge assembly 1, or may be indirectly slidably coupled to the hinge assembly 1 via other structures, such as the first slider assembly 2. When the second sliding assembly 3 is directly slidably connected to the hinge assembly 1, the sliding connection between the first sliding assembly 2 and the hinge assembly 1 can be referred to, and will not be described herein.

Referring to fig. 8 to 10, the second sliding member 3 is at least partially accommodated in the first sliding slot 21 of the first sliding member 2. Optionally, the second sliding member 3 is slidably connected to a groove wall of the first sliding groove 21. The first sliding assembly 2 is slidably coupled to a groove wall of the sliding groove of the hinge assembly 1. In other words, the second sliding assembly 3, the first sliding assembly 2 and the hinge assembly 1 are nested and slidably connected from inside to outside in sequence.

In another embodiment, the sliding track of the hinge module 1 is located in the first sliding slot 21 of the first sliding module 2 and slidably connected to the slot wall of the first sliding slot 21, and the second sliding module 3 is located in the sliding track of the hinge module 1 and slidably connected to the sliding track.

Alternatively, referring to fig. 4, 5 and 8, the first support 4 may be a support plate, and the first support 4 at least partially covers the hinge assembly 1. In an embodiment, the first support 4 covers the hinge assembly 1. The first support 4 is connected to the first sliding member 2. In this embodiment, the first supporting member 4 is fixedly connected to the first sliding component 2, and in other embodiments, the first supporting member 4 and the first sliding component 2 may also be elastically connected through an elastic member. When the first support 4 is fixedly connected to the first sliding component 2, the specific connection manner thereof includes, but is not limited to, welding, adhesive connection, snap connection, screw connection, and the like.

Further, referring to fig. 5, the first sliding member 2 is used for tensioning the first support 4. Optionally, the first sliding assembly 2 at least includes an elastic member and a sliding block, wherein the sliding block of the first sliding assembly 2 is slidably connected to the hinge assembly 1, the elastic member of the first sliding assembly 2 elastically abuts between the sliding block of the first sliding assembly 2 and the hinge assembly 1, and the sliding block of the first sliding assembly 2 is further fixedly connected to the first supporting member 4, so that the first sliding assembly 2 can slide relative to the hinge assembly 1 and drive at least a portion of the first supporting member 4 to slide relative to the hinge assembly 1. In particular, the elastic member is kept in a compressed state at all times, and therefore, the slider of the first sliding assembly 2 tends to move away from the hinge assembly 1, thereby tightening the first support 4.

Optionally, referring to fig. 4 and 5, the second supporting member 5 and the third supporting member 6 are supporting plates. The second support 5 at least partially covers the housing to which the hinge assembly 1 is connected. Specifically, opposite sides of the hinge assembly 1 are connected to the first and

second housings

10 and 20, respectively. In an embodiment, the second support 5 covers the first housing 10. The third support 6 covers the first housing 10. The second support 5 is connected to the second sliding component 3 of the first sliding assembly 40a, and the connection manner includes, but is not limited to, a fixed connection or an elastic connection. The second sliding member 3 of the first sliding assembly 40a can slide relative to the hinge assembly 1, and drives the second supporting member 5 to slide relative to the hinge assembly 1. The second sliding member 3 of the first sliding unit 40a slides together with the second supporting member 5 in a direction approaching or departing from the hinge assembly 1. Further, there is no direct contact connection between the first support 4 and the second support 5, and the second support 5 can slide in a direction approaching or departing from the first support 4 under the action of the second sliding assembly 3.

The third support member 6 is connected to the second slide module 3 of the second slide assembly 50 a. The second sliding member 3 of the second sliding assembly 50a can slide relative to the hinge assembly 1, and drives the third supporting member 6 to slide relative to the hinge assembly 1. The second sliding member 3 of the second sliding unit 50a slides together with the third supporting member 6 in a direction approaching or separating from the hinge member 1. There is no direct contact connection between the third support 6 and the first support 4. The third support 6 can slide in a direction towards or away from the first support 4 under the action of the second sliding assembly 3.

Optionally, when the bendable support mechanism 200 is in the flat state, the second support member 5, the first support member 4, and the third support member 6 are coplanar and abutted against each other, and are spliced to form a coplanar support surface to support the flexible screen 100. The second support 5, the first support 4 and the third support 6 are arranged along the sliding direction of the first sliding component 2 or the second sliding component 3. Namely, the second support 5, the first support 4 and the third support 6 are sequentially arranged along the Y-axis direction.

Referring to fig. 2 and 4, the first casing 10 is fixedly connected to the second supporting member 5, and the first casing 10 and the first supporting member 4 enclose a space for accommodating the electronic component. The second housing 20 is fixedly connected to the third support 6. The second housing 20 and the second support 5 enclose a receiving space for receiving the electronic components. The first sliding combination 40a is connected to a side of the hinge assembly 1 facing the first housing 10. The second sliding combination 50a is connected to a side of the hinge assembly 1 facing the second housing 20. The hinge assembly 1 is coupled between the first housing 10 and the second housing 20. The first and

second housings

10 and 20 may be relatively rotated by the hinge assembly 1 to be unfolded or folded. The first support 4 is at least partially disposed on the hinge assembly 1. The second support 5 is disposed on the first housing 10. The third support 6 is disposed on the second housing 20. The first support member 4, the second support member 5 and the third support member 6 form an integral support surface, the first housing 10, the hinge assembly 1 and the second housing 20 are disposed on one side of the integral support surface, and the flexible screen 100 is disposed on the other side of the integral support surface.

When the foldable support mechanism 200 is moved from the flat state to the folded state or from the flat state to the folded state, the first support 4, the second support 5, and the third support 6 slide at least partially with respect to the hinge assembly 1.

Specifically, in the process of the bendable supporting mechanism 200 from the flat state to the folded state, the flexible screen 100 is gradually bent from the flat state, the length (along the length in the bending arc direction, which is not described later) of the bending outer side of the flexible screen 100 is unchanged, the length of the bending inner side of the flexible screen 100 is reduced, the first supporting member 4 is clamped between the flexible screen 100 and the hinge assembly 1, the first supporting member 4 is bent along with the bending of the flexible screen 100, and the length of the bent first supporting member 4 in the bending arc direction is reduced. In other words, the portion of the first support 4 on the side of the bending axis slides in a direction close to the central axis of the hinge assembly 1 (the central axis is in the Y-axis direction). The portion of the first support 4 on the other side of the bending axis also slides in a direction close to the central axis of the hinge assembly 1 (the central axis is in the Y-axis direction).

The first sliding component 2 of the first sliding assembly 40a and the first sliding component 2 of the second sliding assembly 50a are both close to the hinge assembly 1 under the driving of the first supporting member 4, so as to adapt to the reduction of the length of the first supporting member 4 along the bending arc direction. Moreover, as the length of the bent inner side of the flexible screen 100 is reduced, the second support 5 and the third support 6 are driven to slide towards the hinge assembly 1, the second sliding component 3 of the first sliding combination 40a slides towards the hinge assembly 1 under the action of the second support 5, and the second sliding component 3 of the second sliding combination 50a slides towards the hinge assembly 1 under the action of the third support 6.

In the process of the bendable supporting mechanism 200 from the folded state to the unfolded state, the flexible screen 100 is gradually unfolded from the folded state, and the length of the bent inner side of the flexible screen 100 is gradually increased. The first support member 4 is flattened along with the flattening of the flexible screen 100, and the length of the first support member 4 along the bending arc direction is gradually increased in the flattening process. In other words, the portion of the first support 4 on the side of the bending axis slides in a direction away from the central axis of the hinge assembly 1 (the central axis is in the Y-axis direction). The portion of the first support 4 on the other side of the bending axis also slides in a direction away from the central axis of the hinge assembly 1 (the central axis is in the Y-axis direction).

Referring to fig. 8, the first sliding component 2 of the first sliding assembly 40a and the first sliding component 2 of the second sliding assembly 50a are respectively connected to the first supporting member 4 at two opposite sides of the bending axis, so that the first sliding component 2 of the first sliding assembly 40a and the first sliding component 2 of the second sliding assembly 50a are both away from the hinge assembly 1 under the action of the first supporting member 4.

The length of the inner side gradually increases due to the bending of the flexible screen 100. The second support 5 and the third support 6 are subjected to a thrust generated by the flexible screen 100 outwards from the bending axis. The second support 5 drives the second sliding component 3 of the first sliding assembly 40a to slide away from the hinge assembly 1 under the pushing force, and the third support 6 drives the second sliding component 3 of the second sliding assembly 50a to slide away from the hinge assembly 1 under the pushing force.

As can be seen from the above, in the process of the bendable support mechanism 200 from the flat state to the folded state or the bendable support mechanism 200 from the folded state to the flat state, the size of the portion of the inner side of the flexible screen 100 that bends corresponding to the first support member 4 changes, the size of the first support member 4 changes corresponding to the flexible screen 100, and the first sliding assembly 2 can slide toward or away from the hinge assembly 1 in compliance with the length change of the first support member 4 (so as to change the length of the inner side of the flexible screen 100 that bends), so as to compensate the size change of the flexible screen 100 in the bending process.

Moreover, the second sliding component 3 of the first sliding assembly 40a and the second sliding component 3 of the second sliding assembly 50a can slide to accommodate the sliding of the first support 4 and the second support 5, so as to accommodate the size change of the flexible screen 100 during the bending process, so as to ensure that the flexible display device 1000 is smoothly bent.

The following provides a specific structural example of the first slider assembly 2 and the second slider assembly 3 of the first slider assembly 40a with reference to the drawings. Of course, the structure of the first sliding member 2 and the second sliding member 3 provided in the embodiments of the present application includes, but is not limited to, the following embodiments.

In a first embodiment, referring to fig. 8 to 10, the first sliding assembly 2 includes a first sliding block 22 and a first elastic element 23. The first slider 22 is fixedly connected to the first support 4. The first elastic member 23 elastically abuts between the first slider 22 and the hinge assembly 1.

Specifically, referring to fig. 8 to 10, the hinge assembly 1 includes a fixing base 11 extending toward the first housing 10 at a side facing the first housing 10, and the fixing base 11 includes a second sliding slot 110. The second chute 110 extends in the Y-axis direction.

Referring to fig. 8 to 10, the fixing base 11 includes a bottom wall 111, a first side wall 112 and a second side wall 113 oppositely disposed on two sides of the bottom wall 111, and a third side wall 114 connected between the first side wall 112 and the second side wall 113. The third side wall 114 is also connected to the bottom wall 111. The first side wall 112, the second side wall 113, the third side wall 114, and the bottom wall 111 enclose the second chute 110. The first and

second sidewalls

112 and 113 are aligned in the X-axis direction. The third side wall 114 faces the side of the first casing 10. The second chute 110 includes a first opening 110a opposite to the bottom wall 111, and a second opening 110 opposite to the third side wall 114.

Referring to fig. 8 to 10, the first slider assembly 2 is located in the second sliding slot 110. Specifically, the first sliding block 22 is located in the second sliding slot 110, and the first sliding block 22 can slide in the second sliding slot 110. Specifically, the first slide 22 and the two opposite sides of the first side wall 112 and the second side wall 113 are both provided with a first guide rail 221 extending along the Y-axis direction in a protruding manner, and the first side wall 112 and the second side wall 113 are both provided with a first guide groove 222 adapted to the first guide rail 221, so that the first slide 22 can stably slide in the second sliding groove 110 along the Y-axis direction. Further, a first intermediate member 24 is disposed in the first guide groove 222, the first intermediate member 24 is located between the first guide groove 222 and the first guide rail 221, and the first intermediate member 24 plays a role of lubrication and wear resistance.

Specifically, the first intermediate member 24 is made of a material including polyoxymethylene (also called "steal"), polypropylene (also called "PP plastic"), or the like.

The first slider 22 may be located entirely within the second sliding groove 110 or partially within the second sliding groove 110, which is not specifically limited in this application.

In this embodiment, referring to fig. 6 and 10, the first opening 110a faces a side away from the first supporting member 4. The fixing base 11 further includes a first through hole 115 penetrating the bottom wall 111. The first through-hole 115 is a strip-shaped hole extending in the sliding direction of the first slider 22. The sliding mechanism 30 further comprises a connecting member 7. The connection member 7 passes through the first through hole 115 and connects the first support member 4 and the first slider 22. Specifically, the connecting member 7 is a bolt and a nut. The bolt penetrates the fixing base 11 from the side of the second sliding groove 110 through the first through hole 115, then penetrates the first supporting member 4, and then is in threaded connection with the nut, so as to fixedly connect the first supporting member 4 with the first sliding block 22. Since the first through hole 115 is a strip-shaped hole, the bolt can slide in the first through hole 115 when the first slider 22 slides.

In other embodiments, the first opening 110a may also face the side of the first support 4, so that the first slider 22 is disposed opposite to the first support 4, and the first slider 22 and the first support 4 can be fixedly connected without disposing the first through hole 115 on the bottom wall 111 of the fixing base 11.

Referring to fig. 8 and 10, the first elastic element 23 is disposed in the first sliding groove 21 and elastically abuts between the end of the first sliding block 22 and the third side wall 114.

In this embodiment, the first elastic member 23 may be a spring. In other embodiments, the first elastic element 23 may also be a spring sheet or elastic plastic, elastic rubber, etc. with better elastic performance.
