The technical scheme described in the embodiment of the application is suitable for the supporting device, the display device comprising the supporting device and the electronic equipment comprising the display device.

Fig. 1 is a schematic structural diagram of a rolling state I of an example of a supporting device 100 according to some embodiments of the present application. Fig. 2 is a schematic structural view of an expanded state II of an example of a support device 100 according to some embodiments of the present application. As shown in fig. 1 and 2, the supporting device 100 includes a winding member 1, a supporting plate body 2, and a supporting rod member 3. The supporting plate body 2 can be rolled in the rolling part 1, and the supporting rod part 3 is connected to the rolling part 1 and the supporting plate body 2.

Since the supporting device 100 is configured to support the flexible display panel 200, so that the flexible display panel 200 is connected to the supporting plate 2 that can be rolled in the rolling member 1, the flexible display panel 200 can be rolled in or unrolled from the rolling member 1 during use. The support rod member 3 is connected between the winding member 1 and the support plate body 2 to adjust the relative position between the winding member 1 and the support plate body 2, and when the support plate body 2 is wound to the winding member 1, the support rod member can also support the support plate body 2 when the support plate body 2 is unfolded.

Fig. 3 is a schematic structural diagram illustrating a shortened state i of the support bar 3 of the support device 100 according to some embodiments of the present application. Fig. 4 is a schematic structural view illustrating an extended state ii of the support bar 3 of the support device 100 according to some embodiments of the present application. As shown in fig. 3 and 4, in some embodiments of the present application, the support rod assembly 3 includes a plurality of telescopic rods 30, each telescopic rod 30 includes a first end 301 and a second end 302, the first end 301 of each telescopic rod 30 is connected to the winding member 1, and the second end 302 is connected to the support plate 2.

The plurality of extendable rods 30 are disposed between the roll-up member 1 and the support plate 2, and the extendable rods 30 are in a contracted state i when the support plate 2 is rolled up to the roll-up member 1, and in an extended state ii when the support plate 2 is unrolled from the flexible display panel 200. Since the extendable rod 30 is connected to the support plate 2 by the second end 302, that is, in case of rolling or unrolling the support plate 2, the extendable rod 30 is shortened from the second end 302 to the first end 301 and is extended from the first end 301 to the second end 302.

In some alternative embodiments, the retractable rod 30 includes several rod bodies 32 with decreasing diameters, and each rod body 32 is slidably connected. In the shortened state i, the rods 32 are sequentially sleeved from the largest to the smallest in diameter and are accommodated in the rod 32 with the largest diameter, and in the extended state ii, the rods 32 are sequentially connected from the largest to the tail in diameter. That is, the telescopic rod 30 forms a telescopic structure by the diameter difference of the rod bodies 32, and the two ends of the rod body 32 with the largest diameter and the rod body 32 with the smallest diameter, which are far away from each other, are the first end 301 and the second end 302. Alternatively, the rods 32 may be of equal length within the same telescoping rod 30.

In some embodiments of the present application, the retractable rod 30 comprises at least one engaging member 31, the engaging member 31 is disposed between the first end 301 and the second end 302, the engaging members 31 of the retractable rods 30 are engaged in the extended state II, and the engaging members 31 are disengaged in the retracted state I.

In the unfolding state II of the supporting device 100, if the supporting plate 2 is to be unfolded, a pulling force needs to be applied to the supporting rod 3, that is, the telescopic rod 30, so that each rod body 32 of the telescopic rod 30 is in the extension state II, and at this time, the engaging member 31 is engaged by the pulling force along the extension direction of the telescopic rod 30, so that each rod body 32 maintains the extension state II, so as to support the supporting plate 2 in the unfolding state II of the supporting device 100. In the rolling state I of the supporting device 100, if the supporting plate 2 is to be rolled, a pressure in the direction of the telescopic rod 30 needs to be applied to the telescopic rod 30, and at this time, the engagement of the engaging member 31 is released, so that the rod body 32 is restored from the extended state ii, and is shortened from the second end 302 to the first end 301, and enters the shortened state I, so that the supporting plate 2 is rolled in the rolling member 1.

Fig. 5 is a schematic structural view of the engaging member 31 of the support bar 3 of the support device 100 according to some embodiments of the present application. As shown in fig. 5, in some alternative embodiments, the engaging members 31 may be disposed at the end-to-end positions of the rods 32. For example, on the first rod 321 and the second rod 322 that are sleeved with each other, at two ends of the first rod 321 and the second rod 322 that are far away from each other, the first rod 321 includes a through hole 311, and the second rod 322 includes a bump 312 and a first elastic element 313. When the first rod 321 and the second rod 322 do not reach the extension state ii, the first elastic element 313 is in a pressed state, and when the first rod 321 and the second rod 322 reach the extension state ii, the first elastic element 313 is reset, so that the protrusion 312 is embedded into the through hole 311 and is engaged with each other. It should be understood that the edges of the through holes 311 and the surfaces of the bumps 312 are smooth to facilitate disengagement when pressure is applied. Alternatively, the engaging member 31 may have other structures.

Alternatively, the length of each extendable rod 30 in the extended state ii may be different due to the different positions of the support plate 2 to which each extendable rod 30 is connected, and thus, the length of each rod body 32 may be determined according to the position of the support plate 2 to which the extendable rod 30 is connected, within the plurality of extendable rods 30. In case the telescopic rod 30 comprises a multi-jointed rod body 32, the telescopic rod 30 may comprise a plurality of engaging members 31.

Referring again to fig. 1 and fig. 2, the supporting device 100 has a rolling state I in which the supporting plate 2 is rolled in the rolling member 1, the plurality of retractable rods 30 are located inside the rolling member 1, and an unfolding state II in which at least a portion of the plurality of retractable rods 30 extends out of the rolling member 1 to support the supporting plate 2, and the second ends 302 of at least a portion of the retractable rods 30 are spaced apart from each other in the first direction X on a side surface of the supporting plate 2 facing the rolling member 1.

In the winding state I, the retractable rod 30 is in the shortened state I, and the retractable rod 30 is located inside the winding member 1, i.e. the second end 302 of the retractable rod 30 connected to the supporting plate 2 is located at least on the surface of the winding member 1, so as to wind the supporting plate 2 on the winding member 1. In the extended state II, the retractable rod 30 is in the extended state II, such that the second ends 302 of the retractable rods 30 are spaced apart from each other in the first direction X on a side surface of the supporting plate 2 facing the roll-up member 1, i.e. such that the plurality of retractable rods 30 support the supporting plate 2 along the first direction X, thereby ensuring the flatness of the flexible panel 200.

In some embodiments of the present application, the winding element 1 is a winding shaft 10, the winding shaft 10 includes an inner shaft 11 and an outer shaft 12, the outer shaft 12 is disposed on the inner shaft 11 and is connected to the inner shaft 11 in a rotatable manner, the first end 301 of the retractable rod 30 is connected to the inner shaft 11, and at least a portion of the retractable rod 30 extends out of the outer shaft 12 in the unfolding state II.

The inner shaft 11 is connected to the telescopic rod 30, the outer shaft 12 is not connected to the telescopic rod 30, and the support plate 2 is wound on the outer shaft 12, that is, the reel 10 is rotated relative to the outer shaft 12 through the inner shaft 11, so that the support plate 2 is wound on the surface of the outer shaft 12 through the telescopic rod 30 and the change of the relative position between the inner shaft 11 and the outer shaft 12. In the embodiment of the present application, in the rolling state I, the plurality of telescopic rods 30 are disposed along the radial direction of the outer shaft 12, the length is equal to the radius of the outer shaft 12, and the included angles spaced from each other are equal, and in the unfolding state II, the plurality of telescopic rods 30 extend out of the outer shaft 12, the length thereof is increased, and the included angles spaced from each other are decreased. That is, the inner shaft 11 may be regarded as a fixed shaft and the outer shaft 12 may be regarded as a rotating shaft. By applying a force to the support plate 2, a pulling force is applied to the extendable rod 30, so that the extendable rod 30 is extended and simultaneously rotated relative to the inner shaft 11 and the support plate 2.

In the present embodiment, in the extended state II, the second ends 302 of the telescopic rods 30 are arranged at intervals in the first direction X on a side surface of the support plate 2 facing the roll-up member 1. Alternatively, the first ends 301 of the telescopic rods 30 may be spaced in other directions, and in this case, the reel 10 includes a plurality of sections of outer shafts 12, the plurality of sections of outer shafts 12 have the same diameter, and are sleeved on the inner shaft 11 at intervals and are connected to the inner shaft 11 in a relatively rotating manner. In the extended state II, the retractable rods 30 are spaced apart from the first direction X and are disposed on a side surface of the supporting plate 2 facing the winding member 1 in the extending direction of the winding shaft 10, so that the supporting plate 2 is stressed and dispersed, and a better supporting effect is achieved.

In some embodiments of the present application, the support plate body 2 comprises a first support portion 21 and a second support portion 22. The first support portions 21 are spaced apart from each other, and the winding member 1 includes a groove (not shown) for fitting the first support portions 21, and at least a part of the first support portions 21 is fitted into the groove, so that the support plate body 2 is fitted to the winding member 1.

The plurality of first supporting portions 21 are arranged on the track of the unfolded supporting plate body 2, and the plurality of extendable rods 30 are connected to the first supporting portions 21 to drive the first supporting portions 21 to move along the track, so that the supporting plate body 2 is in the unfolded state II. In the embodiment of the present application, the first supporting portion 21 is formed in a band shape and extends in the same direction as the reel 10, thereby supporting the flexible display panel 200 covered on the supporting plate body 2. The plurality of first supporting portions 21 and the plurality of grooves of the winding member 1 are engaged with each other so that the first supporting portions 21 are fittingly coupled with the winding member 1.

Optionally, the second end 302 of each telescopic rod 30 is connected to at least part of the first support 21. That is, the number of the first support parts 21 may be equal to or greater than the number of the extensible rods 30. Optionally, the first supporting portion 21 is made of a flexible material, for example, the first supporting portion 21 may be made of a material such as silicone or rubber. The flexible material also has a certain softness and flexibility, so that the first supporting portion 21 can be attached to the surface of the winding member 1 in the winding state I.

In some embodiments of the present application, a plurality of first supporting portions 21 and second supporting portions 22 are sequentially disposed, and the second supporting portions 22 extend along the first direction X and are connected to adjacent first supporting portions 21.

In the present embodiment, the second support portion 22 is formed in a plate shape, and relatively moves away from the roll 1 in the first direction X in the rolled state I and the unrolled state II. The second supporting plate can support the flexible display panel 200 which is not rolled in the rolling member 1. The second support part 22 is interconnected with the adjacent first support part 21 such that the second support part 22 can be moved in parallel in the first direction X by the extensible lever 30 connected with the first support part 21. Optionally, the second supporting portion 22 may be hollowed out to reduce the weight of the second supporting portion 22, so that the supporting device 100 is more convenient to carry.

As shown in fig. 6, in some embodiments of the present application, the display device 1000 further includes a limiting assembly 4, the limiting assembly 4 is disposed on the second supporting portion 22, and in the unfolding state II, the limiting assembly 4 limits a relative position between the second supporting portion 22 and the rolling member 1.

The arrangement of the limiting component 4 can avoid the damage to the structure of the supporting device 100 caused by the overlarge pulling force applied to the supporting plate body 2 in the using process. In this embodiment, the limiting component 4 is disposed at one end of the second supporting portion 22 far away from the rolling member 1, and in the using process, the limiting component 4 can also serve as a component that is pulled by a user to move the second supporting portion 22 so as to drive the supporting plate body 2 to unfold. Accordingly, the spacing assembly 4 may include a force sensor 43 therein.

For example, the position limiting assembly 4 may include a housing 41, a second elastic member 42 and a force sensor 43, the housing 41 is slidably connected to the second supporting portion 22, the force sensor 43 is connected to the second supporting portion 22, the second elastic member 42 is connected to the inner wall of the housing 41 and the force sensor 43, so as to transmit the pressure applied to the housing 41 to the force sensor 43, and alarm or otherwise stop the movement of the supporting plate body 2 when the pressure exceeds a threshold value. Alternatively, the limiting assembly 4 may have other structures.

In some alternative embodiments, the display device 1000 further includes a driving assembly (not shown), which is disposed on the rolling member 1 to roll or unroll the supporting plate 2.

In the present embodiment, the driving assembly may comprise a piezoelectric motor, which drives the inner shaft 11 and the outer shaft 12 of the reel 10 to move relatively through a transmission mechanism, so as to wind or unwind the support plate 2.

The driving assembly may include a measuring device for indicating the degree of expansion of the support panel 2, i.e., controlling the expansion area of the flexible display panel 200, by detecting the relative rotational positions of the inner shaft 11 and the outer shaft 12. Alternatively, the driving assembly may be electrically connected to the force sensor 43 and other components inside the limiting assembly 4, and the embodiment of the present application is not limited herein.
