[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. The singular forms of "a", "said" and "the" used in this disclosure and the appended claims are also intended to include plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0036] At present, various folding screen mobile phone devices have emerged in the market. During the use of folding electronic devices, the two states of closed state and unfolded state need to be switched frequently. At present, the screen pressing block used to support the folding screen is mainly made of rigid and solid materials such as metal and plastic. The degree of fit with the screen is limited and it cannot cooperate well with the opening and closing of the folding screen, causing black spots and other damage to the screen at the hinge position, seriously affecting user use. In addition, when the screen is hit by external force, the screen pressing block cannot support and fit well, which is easy to cause large deformation, resulting in screen damage.

[0037] In this regard, the embodiments of the present disclosure provide a foldable electronic terminal device and a control method thereof. In order to facilitate understanding of the technical solution of the present disclosure, the foldable electronic terminal device and the control method thereof are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.

[0038] See also Figure 1 and Figure 2 As shown, the embodiment of the present disclosure provides a foldable electronic terminal device, which can be an electronic product such as a mobile phone, a tablet computer, a wearable device, a smart bracelet, a smart watch, etc. The foldable electronic terminal device may include a first body 1, a second body 2, a hinge assembly 11, a folding screen 12, and a screen pressing block 10. Among them, the hinge assembly 11 is arranged between the first body 1 and the second body 2. The folding screen 12 is arranged on the first body 1, the second body 2, and the hinge assembly 11. The first body 1 and the second body 2 can rotate relative to each other through the hinge assembly 11, and the folding screen 12 can follow the first body 1 or the second body 2 to achieve expansion or closure. The screen pressing block 10 is arranged between the folding screen 12 and the first body 1 and / or the second body 2 corresponding to the hinge assembly 11, and is arranged in contact with the folding screen 12. It can be understood that the screen pressing block 10 can be arranged between the folding screen 12 and the first body 1 corresponding to the hinge assembly 11, or it can be arranged between the folding screen 12 and the second body 2.

[0039] Under the control of electric current, the screen pressing block 10 can be converted between a flexible form and a solid state to achieve the fitting and pressing of the folding screen 12. In this way, the folding screen 12 can be more closely fitted, and better support and adhesion can be provided during the use of the folding screen 12. Optionally, the screen pressing block 10 may be made of electrorheological fluid material, and the flexible form may include a liquid state. It is understandable that the electrorheological fluid material is a suspension under normal conditions, which can undergo a liquid-solid transition under the action of an electric field. When the applied electric field strength is far below a certain critical value, the electrorheological fluid is in a liquid state. When the electric field strength is far above this critical value, it can be transformed into a solid state. Near the critical value of the electric field strength, the viscosity of the suspension increases with the increase of the electric field strength, and is in a solid-liquid mixed state.

[0040] In some optional embodiments, under current control, the screen pressing block 10 is in a flexible state during the opening and closing process of the folding screen 12, and is in a solid state when the folding screen 12 is in a stationary state. Figure 1 As shown, when the folding screen 12 is in the opening and closing process, the screen pressing block 10 can be in a liquid state, which improves the fit with the folding screen 12 and can well cooperate with the opening and closing of the folding screen 12. Figure 2 As shown, when the folding screen 12 is in a stationary state, such as an unfolded state, the screen pressing block 10 can be transformed from liquid to solid, which can provide better support and adhesion for the folding screen 12, thereby preventing it from undergoing large deformation due to external force and thereby damaging the screen, thereby improving the use efficiency and life of the folding screen.

[0041] It can be understood that the folding screen 12 being in a stationary state may include: the folding screen 12 being in a stationary state in the unfolded position, the folding screen 12 being in a stationary state in the closed position, or the folding screen 12 being in a stationary state in any hovering position between the unfolded position and the closed position. That is, when the folding screen 12 is moving, the screen pressing block 10 is in a flexible form, and is in contact with the folding screen as it moves. When the folding screen 12 is in a stationary state at any position, the screen pressing block 10 is in a solid state, and supports the folding screen.

[0042] Furthermore, when the folding screen 12 is off, the screen pressing block 10 may be in a solid-liquid mixed state. It is understandable that in practical applications, when the folding screen is off, the screen pressing block may only pass a small amount of current in a standby state, so that the screen pressing block can be in a state of waiting to be activated under the action of a small current, so that the screen pressing block can perform a corresponding state transition according to the next action of the folding screen.

[0043] In some optional embodiments, the current of the screen pressing block 10 is controlled to work in different situations according to the use state of the folding screen 12, so that the screen pressing block 10 works in a corresponding state. Optionally, the folding electronic terminal device may also include a main board, which is arranged in the first body 1 or the second body 2, and the main board is electrically connected to the screen pressing block 10, and is used to control the screen pressing block 10 to be powered on or off. It should be noted that controlling the current of the screen pressing block 10 to work in different situations may refer to controlling the screen pressing block 10 to work under different current intensities or current levels.

[0044] It can be understood that when the folding screen is in a stationary state at any position, the screen pressing block 10 can be powered on and in a solid state, playing the role of supporting the screen and preventing the screen from being damaged by large deformation due to external force. During the opening and closing process of the folding screen, the screen pressing block 10 is powered off and changes from a solid state to a liquid state, which can play the role of fitting the screen and prevent the folding screen from being damaged by black spots during use. When the folding screen 12 is off, a small amount of current can be passed through the screen pressing block 10 to convert the screen pressing block 10 into a solid-liquid mixed state, so that the screen pressing block 10 can be in a state of waiting to be stimulated under the action of a small current, which is convenient for the screen pressing block to perform a corresponding state transition according to the next action of the folding screen.

[0045] In some optional embodiments, the folding electronic terminal device may further include a controller and a sensor, and the controller is electrically connected to the sensor and the screen-pressing block 10. The sensor is arranged at the first body 1 or the second body 2 or the hinge assembly 11 or the folding screen 12, and is used to detect the use status of the folding screen 12 and output a detection signal to the controller, and the controller is used to control the control current of the screen-pressing block 10 according to the detection signal, so that the screen-pressing block 10 works in a corresponding state. Optionally, the controller can be the main board, or it can be a main control chip, a single-chip microcomputer, etc. The controller can sense whether the folding screen 12 is currently in the opening and closing process or in a static state, thereby controlling the screen-pressing block 10 to be powered on or off. It should be noted that in addition to setting the sensor, the use status of the folding screen can also be detected by means of a Hall element set at the hinge assembly, and the present disclosure does not limit this.

[0046] It is understandable that when the sensor detects that the folding screen 12 is in the process of opening and closing, the controller can control the screen pressing block 10 to be powered off, so that the screen pressing block 10 can be in a liquid state, improve the fit with the folding screen 12, and can cooperate well with the opening and closing of the folding screen 12. When the sensor detects that the folding screen 12 is in a stationary state, the controller can control the screen pressing block 10 to be powered on, so that the screen pressing block 10 changes from a liquid state to a solid state, which can better support and attach the folding screen 12, avoid it from causing a large deformation caused by external force, thereby damaging the screen, and can improve the use efficiency and life of the folding screen. When the sensor detects that the folding screen 12 is off, the controller can control the screen pressing block 10 to pass a small amount of current, so that the screen pressing block 10 is converted into a solid-liquid mixed state. It should be noted that when the folding screen is in the off or standby state, there are many ways to detect whether there is an operation behavior on the folding electronic terminal device, so as to wake up the folding screen, such as detecting that the folding screen receives a touch operation, an operation on a button, or using various sensors to detect an operation behavior, such as a pressure sensor set in the folding electronic terminal device detects pressure, etc., and the present disclosure does not limit this.

[0047] Furthermore, when the sensor detects that the folding screen 12 is in a collision state or a falling state, it sends an electrical signal to the controller. The controller controls the screen pressing block 10 to convert from a flexible form to a solid form according to the electrical signal, which can protect the folding electronic terminal device.

[0048] See also Figure 3 As shown, in some optional implementations, the sensor may include: a pressure sensor 22 , a resistance sensor 23 or an acceleration sensor 21 .

[0049] Among them, when the sensor adopts a pressure sensor 22, the pressure sensor 22 can be arranged at the four corners of the device body composed of the first body 1 and the second body 2. When the device body is bumped, collided, or squeezed, it senses the pressure and sends out an electrical signal, so that the controller controls the screen pressing block 10 to be energized, changing from liquid to solid, thereby supporting the screen and preventing the folding screen 12 from being damaged by a large deformation caused by the external force of the bump.

[0050] When the sensor adopts the resistance sensor 23, the resistance sensor 23 can be arranged on the edge parts on both sides of the device body composed of the first body 1 and the second body 2. When the device body is controlled by the opening and closing action of the finger, the action is sensed and an electrical signal is sent to make the controller control the screen pressing block 10 to cut off the power, so that the screen pressing block 10 is in liquid state during the opening and closing process of the folding screen 12, which can play the role of sticking to the folding screen 12 and prevent the folding screen from being damaged such as black spots during use.

[0051] When the sensor adopts an acceleration sensor 21, the acceleration sensor 21 can be arranged in the middle area of ​​the body of the device body composed of the first body 1 and the second body 2. When the device body is in a falling state, it can sense a large acceleration, and send out an electrical signal when there is a risk of falling and bumping, so that the controller controls the screen pressing block 10 to be energized and change from liquid to solid, thereby supporting the screen and preventing the folding screen 12 from being damaged by a large deformation caused by the external force caused by the fall.

[0052] In some optional embodiments, the screen pressing block 10 may include a wrapping layer and an inner component disposed in the wrapping layer, wherein the shape of the inner component can be switched between a flexible shape and a solid state. Optionally, the inner component may be made of an electrorheological fluid material. The wrapping layer may be made of a flexible wrapping material that can be flexibly deformed following the shape of the inner component.

[0053] The present disclosure also provides a control method for a foldable electronic terminal device. It should be noted that the control method is applicable to the foldable electronic terminal device described in the above embodiments and implementation methods. Figures 1 to 3 As shown, the control method includes: according to the use state of the folding screen 12, controlling the current of the screen pressing block 10 to work in different situations, so that the screen pressing block 10 can be converted between a flexible form and a solid state. In this way, the screen pressing block can fit the folding screen more closely, and can play a better supporting and attaching role during the use of the folding screen. It should be noted that controlling the current of the screen pressing block 10 to work in different situations may refer to controlling the screen pressing block 10 to work under different current intensities or current levels.

[0054] In some optional embodiments, according to the use state of the folding screen 12, the screen pressing block 10 is controlled to be powered on or off to switch between liquid and solid states, which may include at least one of the following situations:

[0055] (1) During the opening and closing process of the folding screen 12, the screen pressing block 10 is controlled to be in a flexible state.

[0056] (2) When the folding screen 12 is in a stationary state, the screen pressing block 10 is controlled to be converted into a solid state.

[0057] (3) When the folding screen 12 is off, the screen pressing block 10 is controlled to be converted into a solid-liquid mixed state.

[0058] (4) When the folding screen is in a collision state or a falling state, the screen pressing block 10 is controlled to be converted into a solid state.

[0059] It is understandable that the control of the above-mentioned various situations can be achieved through the cooperation of the sensor and the controller. When the sensor detects the use status of the folding screen and outputs a detection signal to the controller, the controller controls the screen pressing block 10 to be powered on or off according to the detection signal, thereby switching between the flexible form and the solid state.

[0060] Specifically, when the sensor detects that the folding screen is hit or that the folding screen is in a falling state and senses a large acceleration, etc., which meet the set conditions, the detection signal is sent to the controller, and the controller controls the screen pressing block 10 to be powered on according to the detection signal, so that the screen pressing block 10 can be transformed from a liquid state to a solid state, so as to better support, protect and attach the folding screen 12, and avoid it from being greatly deformed due to external forces and thus damaging the screen. When the sensor detects that the folding screen is opened and closed by fingers, that is, the folding screen is in the process of opening and closing, the detection signal is sent to the controller, and the controller controls the screen pressing block 10 to be powered off according to the detection signal, so that the screen pressing block 10 is transformed from a solid state to a liquid state, so as to improve the fit with the folding screen 12, and cooperate with the opening and closing of the folding screen 12, so as to improve the use efficiency and life of the folding screen 12. When the folding screen 12 is in a stationary state, the controller controls the screen pressing block 10 to be transformed into a solid state, so as to better support and attach the folding screen 12, and avoid it from being greatly deformed due to external forces and thus damaging the screen, so as to improve the use efficiency and life of the folding screen.

[0061] See also Figure 4 As shown, in actual application, the use process of the foldable electronic terminal device can be as follows:

[0062] 300 starts.

[0063] At 310 , the opening and closing action of the folding screen 12 begins. During the opening and closing process, the screen pressing block 10 is powered off and becomes liquid to fit the screen to cooperate with the opening and closing process.

[0064] 311 When the folding screen 12 is unfolded for use, the screen pressing block 10 is energized to turn it into a solid state to support the screen.

[0065] 312 When the folding screen 12 is off, a small amount of current is passed through the screen pressing block 10 to make it change into a solid-liquid mixed state and wait to be excited.

[0066] 313 When the folding screen 12 is closed, the closing action can be sensed by, for example, a resistance sensor 23, and the screen pressing block 10 is powered off, so that it becomes a liquid state to fit the screen to cooperate with the opening and closing process.

[0067] 314 It can be understood that when the folding screen 12 is in the process of opening and closing, the folding screen 12 is in a bent state, and the screen pressing block 10 is powered off to turn it into a liquid state to fit the screen to cooperate with the opening and closing process.

[0068] The opening and closing action of the 315 folding screen is completed.

[0069] 320 ends.
