The support structure 01 of the embodiment of the application includes a support assembly 10, the support assembly 10 includes a first support 11 and a second support, the second support includes a carrying portion 12 and a bendable portion 13, the bendable portion 13 is located between the first support 11 and the carrying portion 12; the support assembly 10 comprises an unfolded state and a folded state, and the transition of the support assembly 10 between the folded state and the unfolded state can be achieved by the bending of the bendable portion 13. When the supporting assembly 10 is in the unfolded state, the first supporting member 11, the bendable portion 13 and the carrying portion 12 are distributed along the first direction X and disposed in the same layer.

The flexible display panel 02 is disposed at one side of the support structure 01 and covers the support structure 01, the flexible display panel 02 may include a first display part 021, a second display part 022, and a bending display part 023 connected between the first display part 021 and the second display part 022, the first display part 021 may be connected to the first support member 11, the second display part 022 is connected to the carrying part 12, and the bending display part 023 is disposed corresponding to the bendable part 13; by folding and unfolding the support structure 01, folding and unfolding of the flexible display panel 02 can be achieved.

Display device has fold condition and expansion state, and is optional, and at display device's fold condition, bearing structure 01 can be located flexible display panel 02's inboard, and flexible display panel 02 is located the bearing structure 01 outside promptly, and display device is the outer formula of rolling over, and convenient to use, display device also can show the use at fold condition.

Of course, in the folded state of the display device, the supporting structure 01 may also be located outside the flexible display panel 02, that is, the flexible display panel 02 is located inside the supporting structure 01, and the display device is of the inward folded type, which is more beneficial to protecting the flexible display panel 02 and is also within the protection scope of the present application.

It can be understood that the first support 11 has a mounting surface 11a, when the support assembly 10 is applied to a display device, the flexible display panel 02 can be connected to the mounting surface 11a of the first support 11, and the carrying portion 12 can be turned over to a side of the first support 11 away from the mounting surface 11a through the bendable portion 13, so that when the display device is in a folded state, the flexible display panel 02 can be located outside the support structure 01.

Because in the folded state of display device, if display device is the formula of rolling over, the radius of buckling of the display part 023 of flexible display panel 02 is greater than the radius of buckling of the bendable part 13 of support structure 01, so when display device changes from folded state to unfolded state, the display part 023 of bending of flexible display panel 02 has the compression deformation trend, and the display part 023 of bending easily appears the fold phenomenon. If the display device is of the inward folding type, the bending radius of the bending display portion 023 of the flexible display panel 02 is smaller than the bending radius of the bendable portion 13 of the supporting structure 01, so when the display device is changed from the folding state to the unfolding state, the bending display portion 023 of the flexible display panel 02 has a tendency of tensile deformation, and the bending display portion 023 is prone to crack.

In order to solve the problem that the flexible display panel 02 is prone to be uneven or cracked when the display device is unfolded, the support structure 01 provided in the embodiment of the present application further includes a compensation assembly 20, the compensation assembly 20 is connected between the first support 11 and the second support, and the compensation assembly 20 is used for driving the support assembly 10 to switch between the first state and the second state. In the first state, the minimum distance between the first support 11 and the bendable portion 13 in the first direction X is a first distance d1, and in the second state, the minimum distance between the first support 11 and the bendable portion 13 in the first direction X is a second distance d2, and the first distance d1 is smaller than the second distance d2. Optionally, the support assembly 10 is in a first state and a second state, and the first support 11, the bendable portion 13 and the carrying portion 12 are distributed along the first direction X and disposed in the same layer.

According to the supporting structure 01 provided by the embodiment of the application, the supporting component 10 is driven to be switched between the first state and the second state through the compensation component 20, the distance between the first supporting component 11 and the bendable part 13 in the first direction X is adjusted, and further the length of the supporting component 10 in the first direction X can be changed, when the supporting structure 01 is applied to a display device, the length of the supporting component 10 in the first direction X can be matched with the unfolding size of the flexible display panel 02, so that wrinkles or cracks of the bending display part 023 of the flexible display panel 02 can be avoided, the flatness of the display device in the unfolding state is improved, and the appearance and the service life of the display device are improved. The minimum distance between the first support 11 and the bendable portion 13 in the first direction X may be the minimum distance between the ends of the first support 11 and the bendable portion 13 close to each other in the first direction X, or may be the minimum distance between the end of the first support 11 away from the bendable portion 13 and the end of the bendable portion 13 close to the first support 11 in the first direction X.

It can be understood that, for the external folding display device, when the display device is unfolded, after the supporting structure 01 is converted from the folded state to the unfolded state, the supporting assembly 10 may be in the first state first, and then the supporting assembly 10 is converted to the second state through the compensating assembly 20, so as to increase the distance between the first supporting member 11 and the bendable portion 13 in the first direction X, increase the length of the supporting assembly 10 in the first direction X, and further reduce or eliminate the wrinkle occurring at the bendable display portion 023 of the flexible display panel 02; correspondingly, when the display device is folded after being unfolded, the distance between the first supporting piece 11 and the bendable part 13 in the first direction X can be reduced through the compensating assembly 20, the length of the supporting piece 10 in the first direction X is shortened, the supporting piece 10 is changed from the second state to the first state, and then the bearing part 12 is turned to one side of the first supporting piece 11, which is back to the mounting surface 11a, through the bending of the bendable part 13, so that the display device is folded, and the phenomenon that the flexible display panel 02 is excessively stretched and deformed when the display device is folded can be avoided.

Optionally, the difference between the second distance d2 and the first distance d1 may be in a folded state of the display device, and the absolute value of the difference between the arc length corresponding to the bending display portion 023 of the flexible display panel 02 and the arc length corresponding to the bending portion 13 of the support assembly 10 may be used, so that the flexible display panel 02 may not wrinkle or crack when the display device is unfolded, and the flexible display panel 02 may be prevented from stretching and deforming when the display device is folded, thereby further improving the appearance and the service life of the display device.

Alternatively, the first support 11 may include a first housing 111 and a cover plate 112, the first housing 111 has a mounting surface 11a, the cover plate 112 is disposed on a side of the first housing 111 away from the mounting surface 11a, and a cavity for mounting and accommodating an electronic device 03 such as a circuit board, a battery, etc. may be formed between the first housing 111 and the cover plate 112.

Optionally, in the folded state of the supporting assembly 10, and in the second state and the first state during the process of being unfolded to the folded state, the distance Δ d between the second boss 245 and the rail 243 in the first direction X may be the folded state of the display device, and the difference between the arc length corresponding to the bending display portion 023 of the flexible display panel 02 and the arc length corresponding to the bendable portion 13 of the supporting assembly 10 is used to better realize the limiting.

Alternatively, the bendable portion 13 may include a plurality of hinge units 130 connected in sequence, in order to prevent the flexible display panel 02 from being wrinkled when the display device is unfolded and simultaneously prevent the flexible display panel 02 from being stretched and deformed when the display device is folded, in the folded state of the support assembly 10 and the second state and the first state when the display device is unfolded and folded, a distance Δ d between the second boss 245 and the rail 243 in the first direction X may be equal to a difference Δ L between the second distance d2 and the first distance d1, that is, Δ d = pi R-n × 2rsin (90/n), where n is the number of hinge units 130 of the bendable portion 13, R is a bending radius of the bendable portion 13, and R is a bending radius of the bending display portion 023 of the flexible display panel 02 disposed on the support structure 01.

Alternatively, the protruding direction of the second boss 245 with respect to the connecting rod 241 may be opposite to the protruding direction of the first boss 242 to avoid the second boss 245 from affecting the reciprocating movement of the guide rod 244 and the push-pull member 22 in the first direction X.

In some optional embodiments, to facilitate the connection between the connecting rod 241 and the bendable portion 13, the second adaptor may further include a second connecting member 246, the second connecting member 246 connects the connecting rod 241 and the bendable portion 13, and the hinge rod 131 at one end of the bendable portion 13 near the first support 11 can rotate relative to the second connecting member 246. Optionally, the first connecting member 122 has a protrusion, which is at least partially inserted into the receiving groove 1313 of the hinge rod 131 and is rotatably connected to the hinge rod 131.

In bearing structure 01's fold condition, first mounting and second mounting magnetic adsorption, bearing portion 12 is connected through fixed subassembly with first support piece 11, can avoid bearing structure 01 to open by accident, and when bearing structure 01 need expand, with first mounting and the separation of second mounting, upset bearing portion 12 makes bearing portion 12, bendable portion 13 and first support piece 11 set up with the layer.

Alternatively, the first fixing member and the second fixing member may be magnets.

Fig. 17 is a flowchart of a working method of the support structure according to an embodiment of the present disclosure.

The embodiment of the present application further provides a working method of the support structure 10, where the support structure 10 may be the support structure 10 described in any of the above embodiments, and the working method of the support structure 10 provided in the embodiment of the present application includes steps S100 to S400.

In step S100, the bendable portion 13 is changed from a bent state to a flattened state, so that the first supporting member 11, the bendable portion 13, and the carrying portion 12 are distributed along the first direction X and disposed in the same layer.

In step S200, the minimum distance between the first support 11 and the bendable portion 13 in the first direction X is adjusted by the compensation assembly 20 in a first manner. Wherein the first manner comprises increasing or decreasing.

In step S300, the compensation assembly 20 adjusts the minimum distance between the first support 11 and the bendable portion 13 in the first direction X in a manner opposite to the first manner.

In step S400, the bendable part 13 is changed from the flattened state to the bent state.

After the bendable part 13 is changed into the flat state by the bending state, adjust the distance of the first support part 11 and the bendable part 13 on the first direction X through the compensation component 20, and then can change the length of the support component 10 on the first direction X, then when the support structure 01 is applied to the display device, the length of the support component 10 on the first direction X can be matched with the expansion size of the flexible display panel 02, and then the fold appears in the bending display part 023 of the flexible display panel 02, improve the flatness under the unfolding state of the display device, and improve the appearance and the service life of the display device.

When the support structure 10 is applied to a fold-out display device (i.e. the flexible display panel 02 is located outside the support structure 01 in a folded state of the display device), the working method of the support structure 10 provided by the embodiment of the present application may include:

changing the bendable part 13 from a bent state to a flattened state, so that the first support 11, the bendable part 13 and the bearing part 12 are distributed along the first direction X and are arranged in the same layer; increasing the minimum distance between the first support 11 and the bendable part 13 in the first direction X by the compensation assembly 20; reducing the minimum distance between the first support 11 and the bendable portion 13 in the first direction X by the compensation assembly 20; the bendable portion 13 is changed from the flattened state to the bent state.

For the external folding display device, because the bending radius of the bendable part 13 of the support structure 10 is smaller than the bending radius of the bendable display part 023 of the flexible display panel 02 when the support structure 01 is converted from the folding state to the unfolding state to unfold the display device, the position of the bendable display part 023 of the flexible display panel 02 is wrinkled, at this time, the distance between the first support part 11 and the bendable part 13 in the first direction X is increased through the compensation assembly 20, the length of the support assembly 10 in the first direction X is increased, and the wrinkles appearing at the position of the bendable display part 023 of the flexible display panel 02 can be reduced or eliminated; correspondingly, when the display device is folded, the distance between the first support part 11 and the bendable part 13 in the first direction X can be reduced through the compensation component 20, the length of the support component 10 in the first direction X is shortened, and then the bearing part 12 is turned to one side of the first support part 11, which is opposite to the mounting surface 11a, through the bending of the bendable part 13, so that the display device is folded, and the flexible display panel 02 can be prevented from being stretched and deformed excessively when the display device is folded.

When the support structure 10 is used in a foldable display device (i.e. when the flexible display panel 02 is located inside the support structure 01 in a folded state of the display device), the working method of the support structure 10 provided by the embodiment of the present application may include:

changing the bendable part 13 from a bent state to a flattened state, so that the first support 11, the bendable part 13 and the bearing part 12 are distributed along the first direction X and are arranged in the same layer; reducing the minimum distance between the first support 11 and the bendable portion 13 in the first direction X by the compensation assembly 20; increasing the minimum distance between the first support 11 and the bendable part 13 in the first direction X by the compensation assembly 20; the bendable portion 13 is changed from the flattened state to the bent state.

For the foldable display device, because the bending radius of the bendable portion 13 of the supporting structure 10 is greater than the bending radius of the bendable display portion 023 of the flexible display panel 02 when the supporting structure 01 is converted from the folded state to the unfolded state to unfold the display device, the bendable display portion 023 of the flexible display panel 02 is over-stretched, and at this time, the compensation assembly 20 reduces the distance between the first supporting member 11 and the bendable portion 13 in the first direction X, reduces the length of the supporting member 10 in the first direction X, and further can reduce or avoid the over-stretched deformation of the bendable display portion 023 of the flexible display panel 02; correspondingly, when the display device is folded, the distance between the first supporting piece 11 and the bendable part 13 in the first direction X can be increased through the compensating assembly 20, the length of the supporting assembly 10 in the first direction X is increased, and then the bearing part 12 is turned over to one side of the first supporting piece 11, which is opposite to the mounting surface 11a, through the bending of the bendable part 13, so that the display device is folded, and the fold of the bending display part 023 of the flexible display panel 02 can be avoided.

In some alternative embodiments, when the compensating assembly 20 comprises the driving member 21, the push-pull member 22, and the adapter assembly; in the working method of the support structure 10 provided in the embodiment of the present application, the step S100 may include:

the driving member 21 drives the pushing and pulling member 22 to slide away from the first supporting member 11, so that the pushing and pulling member 22 pushes the foldable portion 13 to change from the bending state to the flattening state.

The driving part 21 drives the pushing and pulling part 22 to move towards the direction far away from the first supporting part 11, so that the bendable part 13 is converted into a flattening state from a bending state, and then the supporting structure 10 is converted into an unfolding state from a folding state.

The working method of the support structure 10 provided in the embodiment of the present application may further include, between step S200 and step S300: the driving member 21 drives the push-pull member 22 to slide toward the first supporting member 11 until the end of the push-pull member 22 away from the first supporting member 11 slides to the end of the foldable portion 13 close to the first supporting member 11.

Before the compensation assembly 20 adjusts the minimum distance between the first supporting member 11 and the bendable portion 13 in the first direction X in a manner opposite to the first manner, the driving member 21 drives the push-pull member 22 to move in the first direction X toward the direction close to the first supporting member 11, so as to reset the push-pull member 22, thereby preventing the push-pull member 22 from affecting the bending of the bendable portion 13.
