The folding scheme can solve this problem, which is convenient to carry and can realize large screen display. Therefore, folding electronic equipment gradually emerges.

[0003] However, the display screen of the current folding electronic equipment will be stretched and compressed in the stacking position of the folding position, and the folding position will appear a folding phenomenon, which affects the display effect and needs to be improved. SUMMARY

[0004] The embodiments of the present application provide a folding terminal and a control method to solve the problem that the folding terminal affects the display effect due to the folding on the display screen.

[0005] In a first aspect, the embodiments of the present application provide a folding terminal, comprising: a support part, two support parts are arranged at intervals along a first direction, and a bending area is arranged between the two support parts; a screen body connected to one side of the two support parts in a second direction and covering the bending area, a connecting piece is arranged in the bending area to make the screen body foldably arranged around the bending area, the first direction is the length direction of the screen body, and the second direction is the thickness direction of the screen body, wherein at least one cavity is arranged in the bending area, a storage device is arranged on at least one support part, the storage device and the cavity are communicated, and the storage device injects fluid medium into the cavity when the screen body is in an unfolded state.

[0006] In a second aspect, the embodiments of the present application provide a control method for controlling the folding terminal of any one of the first aspect, comprising:

[0007] Detecting the state of the screen body;

[0008] When the screen body is in an unfolded state, the storage device is filled with fluid medium into the cavity, and when the screen body is in a folded state, the cavity discharges fluid medium into the storage device.

[0009] In this way, the folding terminal provided by the embodiment of the present application comprises support parts and a screen body. The two support parts are arranged at intervals along a first direction. A bending area is arranged between the two support parts.

[0028] The first direction X, the second direction Y, and the third direction Z mentioned below are specifically indicated by the arrows in the figure. The setting of the first direction X, the second direction Y, and the third direction Z is only to more clearly illustrate the structure of the connecting member and electronic device provided in the embodiments of this application, and does not limit the direction of the embodiments of this application.

[0029] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a foldable terminal according to some embodiments of this application; Figure 2 This is a cross-sectional view of the folding terminal at point AA, representing some embodiments of this application.

[0030] Firstly, such as Figure 1 and Figure 2 As shown, this application embodiment provides a folding terminal 100, which includes a support portion 110 and a screen 120. Two support portions 110 are spaced apart along a first direction X, and a bending area 130 is provided between the two support portions 110. The screen 120 is connected to one side of the two support portions 110 in a second direction Y and covers the bending area 130. A connector 132 is provided in the bending area 130 to allow the screen 120 to be folded around the bending area 130. The first direction X is the length direction of the screen 120, and the second direction Y is the thickness direction of the screen 120. At least one chamber 131 is provided in the bending area 130, and a storage device 111 is provided on at least one support portion 110. The storage device 111 communicates with the chamber 131. When the screen 120 is in the unfolded state, the storage device 111 injects a fluid medium into the chamber 131.

[0031] The foldable terminal 100 with a flexible screen often develops creases (in the form of indentations or protrusions) on its screen body 120 after repeated bending. In existing technologies, mechanical structures such as connectors 132 are often used to press against the two side walls of the bending area 130, i.e., the surfaces of the opposing support portions 110, to assist the screen body 120 in extending and reduce the risk of crease formation. However, in this embodiment, a fluid medium is filled into the chamber 131 located in the bending area 130 by a storage device 111. This fluid medium presses against the two support portions 110 to assist the screen body 120 in extending. Compared to mechanical structures such as connectors 132, the method of injecting fluid medium into chamber 131 is more controllable. By adjusting the injection volume, the pressure of the fluid medium on the support 110 can be precisely adjusted; it can make the support 110 more uniformly stressed; and the fluid medium can provide support force to the screen 120 in the second direction Y, so as to alleviate the problem of creases caused by the screen 120 collapsing into the bending area 130 when the screen 120 is in the unfolded state.

[0032] Optionally, the support part 110 is provided with a folding terminal 100 function assembly, and the support part 110 is provided with a containing space for containing the storage device 111.

[0033] Optionally, the connecting piece 132 is arranged in the cavity 131, and / or the connecting piece 132 is arranged outside the cavity 131.

[0034] Optionally, the connecting piece 132 is a hinge.

[0035] Optionally, the fluid medium is a liquid or a gas, and examples of the fluid medium are paraffin oil, glycerol, compressed air and other liquids or gases with good fluidity, non-corrosiveness and non-toxicity.

[0036] Optionally, the bending area 130 is provided with one or more cavities 131, and the cavity 131 is a closed cavity 131, which has no other openings except an opening in communication with the storage device 111.

[0037] Optionally, the folding terminal 100 in the embodiment of the application includes but is not limited to a mobile phone, a personal digital assistant (PDA), a tablet computer, an electronic book, a smart fixed telephone and the like.

[0038] In the folding terminal 100 provided by the embodiment of the application, the folding terminal 100 includes a support part 110 and a screen body 120, two support parts 110 are arranged at intervals along a first direction X, a bending area 130 is arranged between the two support parts 110, the screen body 120 is connected to one side of the two support parts 110 in a second direction Y and covers the bending area 130, a connecting piece 132 is arranged in the bending area 130, the screen body 120 is arranged to be folded around the bending area 130, a storage device 111 is arranged on at least one support part 110, the storage device 111 contains a fluid medium, at least one cavity 131 is arranged in the bending area 130, the storage device 111 and the cavity 131 are in communication, when the screen body 120 is in an unfolded state, the storage device 111 injects the fluid medium into the cavity 131, the support part 110 is pressed in the first direction X by the fluid medium, and the screen body 120 is stretched by the support part 110, thereby reducing the risk of creases of the screen body 120 in the bending area 130, and the fluid medium in the cavity 131 can provide support to the screen body 120 in the second direction Y, thereby reducing the risk of creases of the screen body 120 in the bending area 130.

[0039] Therefore, in the embodiments of the present application, the fluid medium is injected into the cavity 131 in the bending area 130 through the storage device 111, so that the fluid medium can provide support to the screen body 120 in the second direction Y, and the fluid medium can also realize the effect of stretching the screen body 120 by extruding the support part 110, so as to reduce the risk of creases in the bending area 130 and improve the display effect of the folding terminal 100. In some embodiments, as shown in Figure 2 The bending area 130 includes a bottom wall 135 opposite to the screen body 120 in the first direction X, and side walls (not shown in the figure) arranged at both ends of the bending area 130 in the third direction Z, the two side walls, the bottom wall 135, the two support parts 110 and the screen body 120 enclose the cavity 131, and the third direction Z is the width direction of the screen body 120, wherein the length of the cavity 131 and the length of the support part 110 are the same in the third direction Z.

[0040] Optionally, the bottom wall 135 is made of flexible material. In the embodiments of the present application, the cavity 131 arranged in the bending area 130 and the storage device 111 communicating with the cavity 131 can alleviate the crease problem of the screen body 120. Similarly, the embodiments of the present application can also alleviate the crease problem of the bottom wall 135.

[0041] Optionally, the cavity 131 is a capsule cavity of a flexible capsule arranged in the bending area 130. After the storage device 111 fills the fluid medium into the cavity 131, the capsule wall of the flexible capsule can be attached to the surface of the bending area 130. By arranging the flexible capsule, the risk of direct contact of the fluid medium with the screen body 120, causing corrosion of the screen body 120 or short circuit of the screen body 120, can be reduced.

[0042] Optionally, the surface of the bending area 130 is coated with a sealing layer to reduce the corrosiveness of the fluid medium to the support part 110 and the screen body 120.

[0043] Optionally, a plurality of cavities 131 are arranged in the bending area 130 in the third direction Z, and each cavity 131 communicates with a separate storage device 111, so that when the sealing property of one of the cavities 131 is damaged, only the separate storage device 111 can be closed, so that the overall function of the folding terminal 100 is reduced but not completely lost.

[0044] In these embodiments, the length of the cavity 131 in the third direction Z is the same as the length of the support part 110, so as to increase the contact area of the cavity 131 and the screen body 120, improve the stretching effect of the cavity 131 on the screen body 120, reduce the risk of creases of the screen body 120, and improve the display effect of the folding terminal 100.

[0045] In some embodiments, as shown in Figure 2As shown, at least two storage devices 111 are arranged in the support part 110, and a communicating port (not shown) is arranged on the chamber 131, and the storage device 111 communicates with the chamber 131 through the communicating port.

[0046] In some embodiments, as shown in Figure 2 As shown, the storage device 111 is arranged on each of the two support parts 110.

[0047] Optionally, one or more storage devices 111 are arranged on each of the two support parts 110, or only one or more storage devices 111 are arranged on one of the support parts 110.

[0048] Optionally, the chamber 131 communicates with one storage device 111 through the communicating port, so as to improve the injection rate of the storage device 111 into the chamber 131, or the chamber 131 communicates with multiple storage devices 111 through the communicating port, so as to reduce the number of communicating ports and improve the sealing performance of the chamber 131.

[0049] In these embodiments, at least two storage devices 111 are arranged in the support part 110, and a communicating port is arranged on the chamber 131, and the storage device 111 communicates with the chamber 131 through the communicating port, and multiple storage devices 111 are arranged, so as to improve the injection rate of the storage device 111 into the chamber 131, improve the filling speed of the chamber 131, and improve the reliability of the folding terminal 100. In addition, the storage device 111 is arranged on each of the two support parts 110, so as to balance the stress of the two support parts 110.

[0050] Please refer to Figure 2 and Figure 3 , Figure 3 for the cross-sectional structure schematic diagram of the folding terminal of some other embodiments of the present application.

[0051] In some embodiments, as shown in Figure 2 and Figure 3 , a flow sensor 112 is arranged in the storage device 111, and the flow sensor 112 is used to detect the volume information of the fluid medium injected by the storage device 111 into the chamber 131, and / or detect the volume information of the fluid medium sucked out of the chamber 131 by the storage device 111.

[0052] In some other embodiments, as shown in Figure 2 and Figure 3 , the storage device 111 comprises a storage tank 113 and a driving member 114, the storage tank 113 is used to store the fluid medium, and the driving member 114 is used to control the storage tank 113 to inject the fluid medium into the chamber 131 or control the storage tank 113 to suck out the fluid medium from the chamber 131.

[0053] The storage device 111 comprises a storage tank 113 and a driving member 114. Exemplarily, one or more flow sensors 112 are arranged in the storage tank 113 or at an opening of the storage tank 113, or a flow sensor 112 is arranged at the communicating port 133 of the cavity 131. The flow sensor 112 can detect the volume of the fluid medium injected into the cavity 131 from the storage tank 113 or the volume of the fluid medium sucked out of the cavity 131.

[0054] First, a preset fluid medium volume value V1 is set. When the screen body 120 is in the unfolded state, the driving member 114 drives the storage tank 113 to inject the fluid medium into the cavity 131 until the cavity 131 is filled with the fluid medium. When the actual volume value V2 of the fluid medium entering the cavity 131 detected by the flow sensor 112 is equal to the preset fluid medium volume value V1, the driving member 114 and the storage tank 113 stop. When the actual volume value V2 of the fluid medium entering the cavity 131 detected by the flow sensor 112 is greater than the preset fluid medium volume value V1, the driving member 114 sucks part of the fluid medium in the cavity 131 into the storage tank 113. When the actual volume value V2 of the fluid medium entering the cavity 131 detected by the flow sensor 112 is less than the preset fluid medium volume value V1, the driving member 114 fills part of the fluid medium in the storage tank 113 into the cavity 131.

[0055] Please refer to Figure 4 and Figure 5 , Figure 4 A cross-sectional structure schematic view of the folding terminal of some other embodiments of the present application at A-A; Figure 5 A cross-sectional structure schematic view of the folding terminal of some other embodiments of the present application at A-A.

[0056] Exemplarily, as shown in Figure 4 , due to multiple folding of the folding terminal 100, the screen body 120 appears a folding crease in the form of concave or convex. When the screen body 120 appears a folding crease convexly away from the bending area 130, the volume of the cavity 131 is increased. When the cavity 131 is filled with the fluid medium, the flow sensor 112 detects that the actual volume value V2 of the fluid medium entering the cavity 131 is greater than the preset fluid medium volume value V1. The flow sensor 112 controls the driving member 114 to suck the fluid medium in the cavity 131 into the storage tank 113. The part of the screen body 120 convexly in the cavity 131 is corresponding to the part of the fluid medium sucked back into the storage tank 113. The part of the screen body 120 convexly will be subjected to a suction force towards the inside of the cavity 131, which alleviates the convex folding crease in the screen body 120.

[0057] Exemplarily, as shown in Figure 5As shown, when the screen 120 has a crease that is recessed toward the bending area 130, the volume of the chamber 131 decreases. After the chamber 131 is filled with fluid medium, the flow sensor 112 detects that the actual volume value V2 of the fluid medium entering the chamber 131 is less than the preset fluid medium volume value V1. The flow sensor 112 controls the drive unit 114 to fill the chamber 131 with the fluid medium in the storage tank 113. The recessed part of the screen 120 will be pushed toward the outside of the chamber 131, which will alleviate the recessed crease in the screen 120.

[0058] Optionally, the drive unit 114 is a micro motor.

[0059] Optionally, the sum of the volumes of all storage tanks 113 should be greater than the volume of chamber 131.

[0060] Optionally, the storage tank 113 has a regular three-dimensional shape, which reduces the difficulty of manufacturing the storage tank 113. For example, the storage tank 113 is an elliptical storage tank 113.

[0061] Optionally, the support 110 is provided with several functional components and gaps between each functional component. The storage tank 113 is designed to match the shape of each gap in order to reduce the overall volume of the support 110 and improve the space utilization of the folding terminal 100.

[0062] Optional, such as Figure 3 As shown, one or more pressure sensors 134 are provided on the inner wall of the chamber 131. The pressure sensors 134 are used to detect the pressure information of the fluid medium in the chamber 131.

[0063] First, a preset pressure value P1 is set. When the screen 120 is in the unfolded state, the drive unit 114 drives the storage tank 113 to fill the chamber 131 with fluid medium. Then, the pressure sensor 134 obtains an actual pressure value P2. When P2 = P1, the drive unit 114 and the storage tank 113 stop. When P2 > P1, the drive unit 114 draws part of the fluid medium from the chamber 131 into the storage tank 113. When P2 < P1, the drive unit 114 fills the chamber 131 with part of the fluid medium from the storage tank 113.

[0064] Pressure sensor 134 and flow sensor 112 can be set simultaneously to improve the control accuracy of the fluid medium in chamber 131; or only pressure sensor 134 or only flow sensor 112 can be set.

[0065] In the embodiments, the storage device 111 is provided with a flow sensor 112 for detecting the volume information of the fluid medium injected and sucked by the storage device 111 into the chamber 131, and the flow sensor 112 can accurately detect the volume of the fluid medium in the chamber 131, thereby improving the control accuracy and solving the problem of overfilling or underfilling of the chamber 131 by the storage device 111. The storage device 111 includes a storage tank 113 for storing the fluid medium and a driving member 114 for controlling the injection of the fluid medium from the storage tank 113 into the chamber 131 or controlling the suction of the fluid medium from the chamber 131 into the storage tank 113. Through the cooperation of the flow sensor 112, the storage tank 113 and the driving member 114, the volume of the fluid medium in the chamber 131 can be further accurately adjusted, so that when a crease appears on the screen body 120, the volume of the fluid medium in the chamber 131 is adjusted to relieve the crease on the screen body 120, thereby improving the display effect of the folding terminal 100.

[0066] Please refer to Figure 6 , Figure 6 for the structural schematic diagram of the folding terminal of some embodiments of the present application.

[0067] In some embodiments, as shown in Figure 6 , when the screen body 120 is in the folded state, the fluid medium is injected from the chamber 131 into the storage device 111.

[0068] When the screen body 120 is changed from the unfolded state to the folded state, the fluid medium gradually enters the storage device 111, that is, during the folding process of the screen body 120, the fluid medium can still provide support for the bending area 130 to reduce the creases generated during the folding process of the screen body 120.

[0069] Or after the fluid medium enters the storage device 111, the screen body 120 is changed from the unfolded state to the folded state. Since the chamber 131 has been emptied of the fluid medium, the force required for the folding process is smaller, and the operation is convenient.

[0070] Alternatively, when the screen body 120 is in the folded state, the fluid medium is entirely injected from the chamber 131 into the storage device 111. Or when the screen body 120 is in the folded state, the chamber 131 still contains part of the fluid medium, and this part of the fluid medium can fill the gap left in the bending area 130 after folding, thereby providing support for the surface of the bending area 130 and reducing the creases generated during the folding process of the screen body 120. In the embodiments, when the screen body 120 is in the folded state, the fluid medium is injected from the chamber 131 into the storage device 111, so as to reduce the risk of creases generated on the screen body 120 in the bending area 130 during the folding process of the screen body 120.

[0071] Please refer to Figure 2 and Figure 7 ,Figure 7 A flow chart of a folding terminal control method according to some embodiments of the present application.

[0072] In a second aspect, the present application provides a control method for controlling the folding terminal 100 according to any of the embodiments of the first aspect, comprising: Figure 2 And Figure 7 In some embodiments, the present application provides a control method for controlling the folding terminal 100 according to any of the embodiments of the first aspect, comprising:

[0073] Step S1: make the screen body 120 in an unfolded state;

[0074] Step S2: when the screen body 120 is in an unfolded state, make the storage device 111 fill the chamber 131 with fluid medium, and when the screen body 120 is in a folded state, make the chamber 131 discharge the fluid medium into the storage device 111.

[0075] Optionally, the storage device 111 injects the fluid medium into the chamber 131 after the screen body 120 is in an unfolded state, or the storage device 111 injects the fluid medium into the chamber 131 during the process of the screen body 120 changing from a folded state to an unfolded state.

[0076] Optionally, in step S2, a pressure sensor (not shown in the figure) is arranged in the chamber 131, a preset pressure value P3 is arranged in the pressure sensor, and when the storage device 111 injects the fluid medium into the chamber 131, the pressure sensor detects the actual pressure value P4 in the chamber in real time. When P3=P4, it is judged that the storage device 111 has filled the chamber 131 with fluid medium, and the storage device 111 stops running.

[0077] In these embodiments, the storage device 111 fills the chamber 131 located in the bending area 130 with fluid medium, so that the fluid medium can provide support to the screen body 120 in the second direction Y, and the fluid medium can also realize the effect of stretching the screen body 120 by extruding the support part 110, so as to reduce the risk of creases in the bending area 130 and improve the display effect of the folding terminal 100.

[0078] In some embodiments, as shown in Figure 2 The storage device 111 is provided with a flow sensor 112, which is used to detect the volume information of the fluid medium injected and sucked by the storage device 111 into the chamber 131, and after step S2, further comprising:

[0079] Step S3: make the flow sensor 112 detect the volume value V2 of the fluid medium injected by the storage device 111 into the chamber 131,

[0080] When V2 is equal to the preset fluid medium volume value V1, the storage device 111 stops running,

[0081] When V2 is greater than the preset fluid medium volume value V1, the storage device 111 absorbs fluid medium from the chamber 131,

[0082] When V2 is less than the preset fluid medium volume value V1, the storage device 111 injects fluid medium into the chamber 131.

[0083] In these embodiments, the storage device 111 is provided with a flow sensor 112, and the volume information of the fluid medium injected by the storage device 111 into the chamber 131 is detected by the flow sensor 112, so as to accurately detect the volume of the fluid medium in the chamber 131, improve the control accuracy, and improve the problem of overfilling or underfilling of the storage device 111 into the chamber 131.

[0084] In some embodiments, as shown in Figure 2 and Figure 4 After step S3, the following steps are included:

[0085] The storage device 111 is allowed to absorb fluid medium from the chamber 131;

[0086] When V2 is equal to the preset fluid medium volume value V1, the storage device 111 stops running.

[0087] In these embodiments, after the screen body 120 is bent for multiple times, creases will inevitably appear. The creases can be protrusions away from the bending area 130. Due to the protruding creases, the volume of the chamber 131 is increased. When the storage device 111 fills the chamber 131 with fluid medium, the flow sensor 112 detects that the volume value V2 of the fluid medium actually injected into the chamber 131 is greater than the preset fluid medium volume value V1. At this time, the driving member 114 absorbs the fluid medium in the chamber 131 into the storage tank 113, and the protruding part of the screen body 120 is subjected to suction force towards the bending area 130, so as to alleviate the problem of the protruding creases on the screen body 120 and improve the display effect of the folding terminal 100.

[0088] In some embodiments, as shown in Figure 2 and Figure 5 After step S3, the following steps are included:

[0089] The storage device 111 is allowed to continue to inject fluid medium into the chamber 131;

[0090] When V2 is equal to the preset fluid medium volume value V1, the storage device 111 stops running.

[0091] In these embodiments, creases inevitably appear after the screen 120 is bent multiple times. The creases may be indentations facing the bending area 130. Due to the indentation creases, the volume of the chamber 131 decreases. When the storage device 111 fills the chamber 131 with fluid medium, the flow sensor 112 detects that the actual volume value V2 of the fluid medium injected into the chamber 131 is less than the preset fluid medium volume value V1. At this time, the fluid medium in the storage tank 113 of the drive component 114 fills the chamber 131. The indented part of the screen 120 is subjected to a thrust away from the bending area 130 to alleviate the problem of indentation creases on the screen 120 and improve the display effect of the folding terminal 100.
