[0050] Here, the exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0051] A rollable screen, also known as a rollable display, is a flexible screen that can contract and expand like a scroll. Since the rollable screen has a smaller volume after contraction and the scroll screen can maintain better smoothness of the screen after expansion, the rollable screen has good application prospects.

[0052] In the related art, the expansion and contraction of the rollable screen are achieved by two motors respectively driving the movement of the upper and lower corners of the movable end of the rollable screen. Exemplarily, as Figure 1 shown, during the expansion process of the rollable screen, the two motors simultaneously drive the upper corner and the lower corner of the movable end of the screen to move in the expansion direction. This method requires two motors controlled by software synchronization. However, in actual applications, due to factors such as the wire length, the control signal transmission path, and the design of the control process, the upper corner and the lower corner of the movable end cannot achieve absolute synchronization, resulting in the rollable screen being unable to expand or contract smoothly and possibly causing damage to the rollable screen.

[0053] In addition, in the above method, since the number of motors for driving the contraction and expansion of the rollable screen is fixed, the ways of contracting and expanding the rollable screen are also relatively single, and users cannot adopt different control methods for the rollable screen according to different scenarios, resulting in the problem of inflexible control.

[0054] In view of the above problems, embodiments of the present disclosure provide a screen assembly, a screen assembly control method, an electronic device, and a storage medium. By connecting a push rod to the movable end of the curling screen and driving the push rod to move through a power device and a transmission device, the movable end of the curling screen can be driven to move at the same speed as the push rod, so that each position of the movable end of the curling screen can move synchronously, ensuring the smoothness of the unfolding and contraction of the curling screen.

[0055] Figure 2 is a schematic structural diagram of a screen assembly shown according to an exemplary embodiment, as Figure 2 shown, the screen assembly 100 may include a curling screen 110, a power device 120, a transmission device 130, and a push rod 140, wherein:

[0056] The curling screen 110 includes a fixed end 111 and a movable end 112, and the movable end 112 of the curling screen 110 may be connected to the push rod 140. Optionally, the movable end 112 of the curling screen 110 may be connected to the side surface of the push rod 140 and perpendicular to the end surface of the push rod 140.

[0057] The power device 120 is drivingly connected to the push rod 140 through the transmission device 130. The power device 120 is configured to provide power to the push rod 140 through the transmission device 130, so that the push rod 140 drives the movable end 112 of the curling screen 110 to move away from or close to the fixed end 111 of the curling screen 110, realizing the unfolding or contraction of the curling screen 110.

[0058] In practical applications, by way of example, as Figure 3 shown, during the process of the screen assembly 100 unfolding the curling screen 110, the power device 120 may apply a thrust to the middle position of the push rod 140 through the transmission device 130. This thrust can drive the push rod 140 to move in the unfolding direction of the curling screen 110. When the push rod 140 moves, it can drive the movable end 112 of the curling screen 110 to move away from the fixed end 111, thereby realizing the smooth unfolding of the curling screen 110. Similarly, when the push rod 140 moves in the contraction direction of the curling screen 110, it can drive the movable end 112 of the curling screen 110 to close to the fixed end 111, thereby realizing the smooth contraction of the curling screen 110.

[0059] Among them, the screen assembly 100 has two screen active tracks for setting the curling screen 110. The screen active tracks are arranged along the unfolding direction of the curling screen 110. The upper edge and the lower edge of the curling screen 110 are respectively located in the two screen active tracks. The two ends of the push rod 140 are respectively arranged in the two screen active tracks. When the push rod 140 moves in the two screen active tracks, it can drive the active end 112 of the curling screen 110 to move in the screen active tracks. Among them, the two screen active tracks are parallel to each other, and the screen active tracks are perpendicular to the push rod 140.

[0060] In some embodiments, the power device 120 includes at least one motor, and the output shaft of the at least one motor is drivingly connected to the transmission device 130.

[0061] Exemplarily, as Figure 4 shown, the power device 120 may further include gears, and the output shaft of the motor may be drivingly connected to the transmission device 130 through one or more gears. For example, when the number of motors is two, the gears connected to the output shafts of the two motors may be drivingly connected to the gears connected to the transmission device 130, so that the transmission device 130 can be driven by two motors. Similarly, the transmission device 130 may also be drivingly connected to more than two motors through a combination of gears.

[0062] In some embodiments, the transmission device 130 includes a telescopic rod. One end of the telescopic rod is connected to the power device 120, and the other end of the telescopic rod is connected to the middle of the push rod 140. The telescopic rod is perpendicular to the push rod 140.

[0063] Exemplarily, the telescopic rod may be a lead screw. In practical applications, please refer to Figure 4 again. When the two motors drive the gears connected to the telescopic rod to rotate forward, the telescopic rod can extend. When the two motors drive the gears connected to the telescopic rod to rotate in reverse, the telescopic rod can shorten. If the telescopic rod extends, the telescopic rod can drive the push rod 140 to move in the direction of the unfolding of the curling screen 110. If the telescopic rod shortens, the telescopic rod can drive the push rod 140 to move in the direction of the contraction of the curling screen 110. Optionally, the transmission device 130 may also be an elastic component, a magnetic component, etc.

[0064] In some embodiments, please refer to Figure 2 again. The screen assembly 100 may further include a pressure sensor 150. The pressure sensor 150 may be disposed on the push rod 140, and the pressure sensor 150 may detect the force on the push rod 140 in the direction opposite to the unfolding direction of the curling screen 110. Optionally, the number of the pressure sensors 150 may be multiple, and the multiple pressure sensors 150 may be evenly distributed on the push rod 140.

[0065] In some embodiments, the screen assembly 100 may further include a distance sensor for detecting the distance between the fixed end 111 and the movable end 112 of the curling screen 110. Optionally, the distance sensor may be a Hall sensor.

[0066] In some embodiments, the screen assembly 100 may further include a controller, which may be electrically connected to the pressure sensor 150, the distance sensor, and the power device 120 respectively. The controller may control the power device 120 according to the acquisition data of the pressure sensor 150 or / and the distance sensor.

[0067] In this embodiment, the screen assembly 100 is constituted by the curling screen 110, the power device 120, the transmission device 130, and the push rod 140. Among them, the curling screen 110 includes a fixed end 111 and a movable end 112, and the movable end 112 of the curling screen 110 is connected to the side surface of the push rod 140. During use, the power device 120 may be in transmission connection with the push rod 140 through the transmission device 130. The power device 120 may provide power to the push rod 140 through the transmission device 130, so that the push rod 140 drives the movable end 112 of the curling screen 110 to move away from or close to the fixed end 111 of the curling screen 110, realizing the unfolding or contraction of the curling screen 110. Since the movable end 112 of the curling screen 110 is driven by the push rod 140, the positions of the movable end 112 of the curling screen 110 can always be consistent with the speed of the push rod 140 during the unfolding or contraction process, so as to achieve synchronous movement, and further ensure that the curling screen 110 can be unfolded and contracted smoothly. In addition, the power device 120 may be composed of multiple motors, so that different combinations of motors can be used to provide power to the push rod 140, making the power supply method diversified and improving the control flexibility of the curling screen 110.

[0068] Figure 5 is a schematic structural diagram of an electronic device 200 including Figure 2 the screen assembly 100 shown. As Figure 5 shown, the electronic device 200 may include a device body 210 and the screen assembly 100 in the above embodiment. The screen assembly 100 is disposed on the device body 210 to serve as a display screen of the electronic device 200.

[0069] Optionally, the screen assembly 100 may be disposed along the length direction of the electronic device 200 or along the width direction of the electronic device 200. That is to say, the curling screen 110 of the electronic device 200 can be unfolded or contracted in the length direction of the electronic device 200, and can also be unfolded or contracted in the width direction of the electronic device 200. Among them, the length direction of the electronic device 200 includes Figure 5above and / or below the electronic device 200, the width direction of the electronic device 200 includes Figure 5 the left side and / or the right side of the electronic device 200.

[0070] Among them, the processor of the electronic device 200 can control the power device 120 according to the pressure sensor 150 and the distance sensor of the screen assembly 100.

[0071] Optionally, the electronic device 200 may include, but is not limited to: smart phones, tablet computers, smart TVs, smart wearable devices, and the like.

[0072] Figure 6 is a flowchart of a screen assembly control method shown according to an exemplary embodiment, as Figure 6 shown, the screen assembly control method may include the following steps:

[0073] In step S101, in response to a user's operation instruction, determine the target working mode of the screen assembly, where the power parameters of the power device are different in different working modes of the screen assembly.

[0074] Exemplarily, in the above embodiment Figure 2 the screen assembly shown or Figure 4 the electronic device shown can be used as an application environment of a screen assembly control method provided by the embodiments of the present disclosure. Hereinafter, the electronic device will be used as the execution subject of the screen assembly control method for description.

[0075] In some embodiments, when the electronic device receives an operation instruction made by the user for the screen assembly, it can respond to the operation instruction and find the working mode corresponding to the operation instruction in the instruction database as the target working mode, so as to determine the target working mode of the screen assembly.

[0076] Exemplarily, the operation instruction may include a touch operation of the user on the screen of the electronic device. For example, the user clicks an icon corresponding to different working modes of the screen assembly in the working mode selection interface. Optionally, the operation instruction may also be an operation made by the user on the corresponding key positions of the electronic device. For example, the user can long-press the unlock key of the electronic device to switch the screen assembly to the working mode corresponding to the operation. Optionally, the operation instruction may also include gesture instructions, voice instructions, etc., which are not limited herein.

[0077] Exemplarily, the working instructions of the screen assembly may include an expansion mode, a contraction mode, a quick expansion mode, a quick contraction mode, a pause mode, and the like.

[0078] In step S102, control the screen assembly to execute an action corresponding to the target working mode.

[0079] Exemplarily, the processor of the electronic device may control the screen assembly to perform actions corresponding to the target working mode. For example, when the target working mode is the unfolding mode, the processor may control the power device of the screen assembly to drive the push rod to move in the unfolding direction of the curling screen, thereby driving the movable end of the curling screen away from the fixed end of the movable curling screen to achieve the unfolding of the curling screen.

[0080] Wherein, in the unfolding mode of the screen assembly, the driving direction of the power device is consistent with the unfolding direction of the curling screen, and the magnitude of the driving force is the initial driving force.

[0081] It can be seen that in this embodiment, by responding to the user's operation instruction, the working mode of the screen assembly is determined. Among them, the power parameters of the power device are different in different working modes of the screen assembly, and the screen assembly is controlled to perform actions corresponding to the working mode, so that different working modes of the screen assembly can be flexibly selected according to different operation instructions of the user to control the screen assembly, and thus the control flexibility of the screen assembly can be improved.

[0082] Figure 7 is a flowchart of a screen assembly control method shown according to another exemplary embodiment. As Figure 7 shown, this method can be applied to a screen assembly as Figure 2 shown or an electronic device as Figure 5 shown. The screen assembly control method may include the following steps:

[0083] In step S201, in response to the user's operation instruction, the target working mode of the screen assembly is determined. Among them, the power parameters of the power device are different in different working modes of the screen assembly, and the power parameters include the driving direction and the driving force.

[0084] In step S202, according to the driving force and the driving direction in the power parameters in the target working mode, the power device is controlled to drive the push rod to move.

[0085] In some embodiments, the working mode of the screen assembly includes a screen unfolding mode, and the screen unfolding mode includes a first unfolding mode and a second unfolding mode. Among them, the driving direction in the power parameters in the first unfolding mode and the driving force direction in the power parameters in the second unfolding mode are both the unfolding direction of the curling screen, and the magnitude of the driving force in the power parameters in the first unfolding mode is different from the magnitude of the driving force in the power parameters in the second unfolding mode.

[0086] In some embodiments, the working modes of the screen assembly include a screen unfolding mode and a screen retracting mode. The driving direction in the power parameters in the screen unfolding mode is opposite to the driving direction in the power parameters in the screen retracting mode, and the driving force in the power parameters in the screen unfolding mode is greater than the driving force in the power parameters in the screen retracting mode.

[0087] In practical applications, the working modes of the screen assembly may include a first working mode, a second working mode, and a third working mode. Among them, the first working mode is a first unfolding mode, the second working mode is a screen retracting mode, and the third working mode is a second unfolding mode. As an implementation, if the target working mode is the first working mode, the power device is driven to drive the push rod to drive the movable end of the scroll screen away from the fixed end of the scroll screen, so as to realize the unfolding of the scroll screen.

[0088] Exemplarily, when the screen assembly is in the first mode, the processor of the electronic device can control the power device to drive the push rod to drive the movable end of the scroll screen away from the fixed end of the scroll screen, so as to realize the unfolding of the scroll screen. Among them, the magnitude of the driving force of the power device in the first working mode can be the initial driving force configured for the screen assembly at the time of factory shipment.

[0089] As another implementation, if the target working mode is the second working mode, the power device is driven to drive the push rod to drive the movable end of the scroll screen close to the fixed end of the scroll screen, so as to realize the retraction of the scroll screen. Among them, the driving force of the power device in the second working mode is less than the driving force of the power device in the first working mode.

[0090] Exemplarily, when the screen assembly is in the second mode, the processor of the electronic device can control the power device to drive the push rod to drive the movable end of the scroll screen close to the fixed end of the scroll screen, so as to realize the retraction of the scroll screen. Among them, the driving direction of the power device in the second mode is opposite to the driving direction of the power device in the first mode. In this embodiment, since the driving force of the power device in the second working mode is less than the driving force of the power device in the first working mode, the impact force of the push rod on the electronic device can be reduced when the screen assembly retracts into the electronic device.

[0091] As yet another implementation, if the target working mode is the third working mode, the power device is driven to drive the push rod to drive the movable end of the scroll screen away from the fixed end of the scroll screen, so as to realize the unfolding of the scroll screen. Among them, the driving force of the power device in the third working mode is greater than the driving force of the power device in the first working mode.

[0092] Exemplarily, when the screen component is in the third mode, the processor of the electronic device can control the power device to drive the push rod to drive the movable end of the curling screen to quickly move away from the fixed end of the curling screen, realizing the rapid unfolding of the curling screen. Among them, the driving direction of the power device in the third mode is the same as that in the first mode. In this embodiment, since the driving force of the power device in the third working mode is greater than that in the first working mode, the screen component can accelerate the unfolding speed of the curling screen according to the user's needs, thereby improving the user experience.

[0093] In some embodiments, the working mode of the screen component may further include a fourth working mode, etc., and the fourth working mode is a rapid contraction mode. When the screen component is in the fourth mode, the processor of the electronic device can control the power device to drive the push rod to drive the movable end of the curling screen to quickly approach the fixed end of the curling screen, realizing the rapid contraction of the curling screen. Among them, the driving direction of the power device in the fourth mode is the same as that in the second mode. In this embodiment, since the driving force of the power device in the fourth working mode is greater than that in the second working mode, the screen component can accelerate the contraction speed of the curling screen according to the user's needs, thereby improving the user experience.

[0094] In some embodiments, the working mode of the screen component may further include a fifth working mode, etc., and the fifth working mode is a pause mode. When the screen component is in the fifth mode, the processor of the electronic device can control the power device to be in an off or standby state. Thus, the movable end of the curling screen is in the current position. In this embodiment, the screen component can stop the movement of the movable end of the curling screen according to the user's needs, thereby improving the user experience.

[0095] In some ways, during the process when the screen component is in any working mode, if a new operation instruction is received, the processor of the electronic device can control the screen component to switch to the working mode corresponding to the new operation instruction, thereby further improving the flexibility of the user to use the screen component.

[0096] In some embodiments, the power device includes a plurality of motors, and the driving force of the power device is positively correlated with the number of motors started by the power device.

[0097] Exemplarily, different working modes of the screen component correspond to different motor combinations. For example, the number of motors started by the power device corresponding to the first mode is less than the number of motors started by the power device corresponding to the third mode. In this embodiment, by combining different numbers of motors to adjust the driving force of the power device, the situation of power waste or overload operation that may be caused by using a fixed motor can be avoided.

[0098] In some other embodiments, the electronic device can also adjust the driving force of the power device by adjusting the power of the starting motor of the power device.

[0099] In some embodiments, the screen assembly further includes a pressure sensor.

[0100] When the processor controls the screen assembly to perform actions corresponding to the working mode, the specific embodiments can be as follows:

[0101] If the pressure sensor is used to detect the pressure on the push rod in the direction opposite to the unfolding direction of the curling screen, and during the process of the power device driving the push rod to drive the movable end of the curling screen away from the fixed end of the curling screen or when the curling screen is in the unfolded state, the detected pressure value is greater than or equal to the pressure threshold, then the power device drives the push rod to drive the movable end of the curling screen to approach the fixed end of the curling screen. Among them, during the process of the movable end of the curling screen approaching the fixed end of the curling screen, the number of motors started by the power device is the maximum number of multiple motors.

[0102] Exemplarily, for example, when the curling screen is in the fully unfolded state or during the unfolding process, when the processor detects that the push rod is subjected to an external resistance, it can timely contract the curling screen back to the initial position at the maximum contraction speed, thereby avoiding damage to the screen.

[0103] In some embodiments, the screen assembly further includes a distance sensor. When the processor controls the screen assembly to perform actions corresponding to the working mode, the specific embodiments can be as follows:

[0104] The distance between the fixed end and the movable end is detected by the distance sensor. If the distance is less than or equal to the first distance or greater than or equal to the second distance, the power device is turned off. Among them, the first distance is less than the second distance. The first distance can be used to determine whether the movable end is close enough to the fixed end to determine whether the curling screen is fully retracted, and the second distance can be used to determine whether the movable end is far enough from the fixed end to determine whether the curling screen is fully unfolded.

[0105] Exemplarily, if the distance between the fixed end and the movable end is less than or equal to the first distance, it indicates that the curling screen has been fully retracted. If the distance between the fixed end and the movable end is greater than or equal to the second distance, it indicates that the curling screen has been fully unfolded. At this time, the electronic device can control the power device to be turned off in time to avoid damage to the electronic device caused by excessive movement of the push rod.

[0106] In some other embodiments, when the processor controls the screen assembly to perform actions corresponding to the working mode, the specific embodiments can be as follows:

[0107] The distance between the fixed end and the movable end is detected by a distance sensor. During the process that the power device drives the push rod to drive the movable end of the curling screen away from the fixed end of the curling screen, the driving force of the power device is adjusted according to the distance, wherein the distance is negatively correlated with the driving force.

[0108] Exemplarily, during the process that the power device drives the push rod to drive the movable end of the curling screen away from the fixed end of the curling screen, that is, during the unfolding process of the curling screen, when the electronic device detects that the distance between the fixed end and the movable end becomes larger, the power device can be controlled to synchronously reduce the driving force. When the curling screen is fully unfolded, the driving force of the power device just reduces to 0. Optionally, the power device can change the driving force by changing the number of starting motors. For example, the distance is negatively correlated with the number of starting motors of the power device. Thereby, when the screen assembly unfolds, it can be avoided that due to the too fast speed of the push rod, a large impact force is caused to the electronic device, and further the electronic device is damaged, ensuring the working safety and stability of the screen assembly.

[0109] In some other embodiments, the processor can detect the distance between the fixed end and the movable end through a distance sensor. During the process that the power device drives the push rod to drive the movable end of the curling screen close to the fixed end of the curling screen, that is, during the contraction process of the curling screen, the driving force of the power device is adjusted according to the distance, wherein the distance is positively correlated with the driving force. For example, when the distance between the movable end and the fixed end of the curling screen is smaller, the driving force of the power device is smaller. When the curling screen finishes contracting, the driving force of the power device just becomes 0. Thereby, when the screen assembly contracts, it can be avoided that due to the too fast speed of the push rod, a large impact force is caused to the electronic device, and further the electronic device is damaged, ensuring the working safety and stability of the screen assembly.

[0110] In this embodiment, by selecting different motor combination modes of the power device according to different working modes selected by the user to provide power, not only the flexibility of controlling the screen assembly can be improved, but also the power consumption in different scenarios can be greatly saved, and the risk of the motor overloading operation can be reduced, greatly increasing the working life of the motor.
