Referring to fig. 6, fig. 6 is a schematic flowchart of an apparatus control method according to an embodiment of the present disclosure. The device control method can be applied to electronic equipment, and the electronic equipment can comprise a telescopic display screen. The flow of the device control method may include:
101. and acquiring the motion instruction, and determining the information of the target position from the motion instruction.
With the continuous development of the technology, the form of the electronic device is also changing. The development from a small screen to a large screen, the development from a simple display screen for displaying images and characters to a touch display screen that can receive a user touch operation, the development from a display screen that cannot be expanded to a display screen that can be expanded, and the like. However, in the related art, in the process of performing the telescopic movement on the telescopic display screen, the problem of low positioning accuracy may occur.
It should be noted that, in the embodiment of the present application, the electronic device may have a retractable display screen. The Retractable Display screen may be a Display screen (The Retractable Display Panel) which can be retracted. The retractable display screen may be a flexible display screen that may be bent, rolled, folded, etc. On an electronic device configured with a retractable display screen, the visible size of the screen can be increased by stretching the retractable display screen, and the visible size of the screen can also be reduced by retracting the retractable display screen. For example, the flexible display 30 of fig. 1-5 is a retractable display.
In this embodiment, for example, the electronic device may obtain a motion instruction, and by analyzing the motion instruction, information of a target position may be determined from the motion instruction, where the target position refers to a destination position to which the retractable display screen needs to be moved in a retractable manner.
102. And controlling the telescopic display screen to perform corresponding telescopic motion according to the information of the target position.
For example, after the information of the target position is determined, the telescopic display screen may be controlled to perform corresponding telescopic motion according to the current position of the telescopic display screen, that is, the telescopic display screen is controlled to perform telescopic motion towards a direction close to the target position.
103. And collecting parameter information of the telescopic display screen in the telescopic motion process.
For example, in the process of performing telescopic motion on the telescopic display screen towards the direction close to the target position, the parameter information of the telescopic display screen in the telescopic motion process can be collected in real time, so that the specific position of the telescopic display screen can be determined according to the parameter information subsequently.
104. And determining the position information corresponding to the telescopic display screen according to the parameter information.
For example, a curve of the correspondence between the parameter information and the position information may be stored in advance. In the process of performing telescopic motion on the telescopic display screen, acquiring parameter information of the telescopic display screen in the telescopic motion process in real time, and matching the parameter information with a curve stored in advance according to the acquired parameter information, so that the position information corresponding to the parameter information can be determined, namely the position information corresponding to the telescopic display screen is determined according to the parameter information.
105. And controlling the telescopic display screen to update the display area according to the position information.
For example, after the position information corresponding to the telescopic display screen is determined, that is, after the telescopic position information of the telescopic display screen is determined, the electronic device may control the telescopic display screen to update the display area according to the position information, for example, when the telescopic display screen performs the contraction motion, the telescopic display screen is controlled to correspondingly reduce the display area, and when the telescopic display screen performs the extension motion, the telescopic display screen is controlled to correspondingly expand the display area. The size of the display area is the same as that of the touchable area, and when the display area is updated, the size of the touchable area is updated accordingly.
In the embodiment of the application, the electronic equipment can acquire the information of the target position from the motion instruction, and then control the telescopic display screen to perform corresponding telescopic motion according to the information of the target position; in the telescopic motion process of the telescopic display screen, parameter information can be collected, and the position information corresponding to the telescopic display screen can be determined according to the parameter information; the electronic device can control the retractable display screen to update the display area according to the position information. In the process of performing telescopic motion on the telescopic display screen, the position of the telescopic display screen can be directly determined according to the collected parameter information, and the telescopic display screen is positioned. Therefore, the positioning accuracy of the electronic equipment can be improved.
Referring to fig. 7, fig. 7 is a second flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method can be applied to electronic equipment, and the electronic equipment can comprise a telescopic display screen. The flow of the device control method may include:
201. and acquiring the motion instruction, and determining the information of the target position from the motion instruction.
The specific implementation of step 201 can refer to the embodiment of step 101, and is not described herein again.
202. And determining the target direction of the telescopic display screen for telescopic motion according to the information of the target position.
For example, the electronic device may further include a driving member, and the driving member may drive the retractable display screen to perform a telescopic motion. For example, the driver is the driver 50 shown in fig. 1 to 5. Referring to fig. 8, fig. 8 is a schematic position diagram of a movement of a driving member according to an embodiment of the present disclosure. Fig. 8 illustrates the movement of the driver from the left end to the right end position. After the information of the target position is determined, namely the terminal position of the telescopic movement of the telescopic display screen is determined, the target direction of the telescopic display screen for the telescopic movement can be determined according to the information of the target position and the current position of the telescopic display screen, and the target direction can be the contraction direction or the extension direction. If the target direction is the contraction direction, the telescopic display screen needs to perform contraction movement, and if the target direction is the extension direction, the telescopic display screen needs to perform extension movement.
For example, in an embodiment, when the driver needs to be driven by the driving mechanism, for example, the driving mechanism may be a motor, such as a stepping motor, and after the target direction of the telescopic movement of the retractable display screen is determined, it may be determined whether the motor rotates forward or backward according to the target direction. If when this telescopic display screen is stretched, the motor is in corotation, when this telescopic display screen is carried out the shrink, the motor is in the reversal, or, when this telescopic display screen is carried out the extension, the motor is in the reversal, when this telescopic display screen is carried out the shrink, the motor is in corotation, etc.
It is understood that the movement command includes an end position of the telescopic movement (i.e., information on the target position), and it is possible to determine whether the direction of rotation of the motor is normal rotation or reverse rotation based on the end position. It should be noted that, the motor rotates a circle, can drive telescopic display screen concertina movement certain distance through driving piece, and the number of circles that the motor rotated and telescopic display screen concertina movement's distance have certain corresponding relation promptly. Therefore, the movement distance of the telescopic display screen can be obtained according to the information of the current position and the target position of the telescopic display screen, and the number of turns of the motor can be converted according to the corresponding relation between the number of turns of the motor and the telescopic movement distance of the telescopic display screen.
203. And controlling the driving piece to drive the telescopic display screen to perform telescopic motion along the target direction.
For example, after the target direction of the telescopic display screen is determined, the electronic device can control the driving part to drive the telescopic display screen to perform telescopic motion along the target direction. If the target direction is the contraction direction, the driving piece is controlled to drive the telescopic display screen to perform contraction movement, and if the target direction is the extension direction, the driving piece is controlled to drive the telescopic display screen to perform extension movement. If need drive the motion of driving member such as motor, this drive the telescopic display screen and carry out concertina movement, then the motor can rotate according to the direction of rotation of confirming and the number of turns of calculating this moment, if when control drives the telescopic display screen and extends, the motor reversal 5 circles, if again when control drives the telescopic display screen and contracts, motor corotation 5 circles etc..
204. In the process that the driving part drives the telescopic display screen to do telescopic motion along the target direction, the magnetic parameters of the magnetic part are collected.
For example, referring to fig. 8, the driving member may be provided with a magnetic member, for example, the magnetic member may be a magnet, and the magnetic member moves along with the driving member during the movement of the driving member. When a driving mechanism such as a motor is required to drive, the motor drives the driving piece to rotate spirally, and when the driving piece rotates spirally, the driving piece can rotate spirally according to the contraction direction of the telescopic display screen or rotate spirally according to the extension direction of the telescopic display screen. Specifically, the direction in which the spiral rotation is performed depends on the target direction of the telescopic movement of the telescopic display screen. If the telescopic display screen does the contraction motion, the driving piece rotates spirally according to the contraction direction of the telescopic display screen, and if the telescopic display screen does the extension motion, the driving piece rotates spirally according to the extension direction of the telescopic display screen.
For example, in an embodiment, the electronic device may further include a housing assembly and a driving mechanism, the housing assembly may include a first housing and a second housing, the first housing and the second housing are capable of moving relatively, the driving member may be disposed on the second housing, the first housing and the second housing together form an accommodating space, and the driving member, the driving mechanism and the plurality of hall sensors are disposed in the accommodating space, as shown in fig. 8, which only shows the hall sensor S1, the hall sensor S2 and the hall sensor S3, and since the magnetic member just moves to the position of the hall sensor S4, the hall sensor S4 is not illustrated.
Referring to fig. 9, fig. 9 is a schematic position diagram of a hall sensor when the retractable display screen provided in the embodiment of the present application is in an extended state. The number of the hall sensors may be plural, and only the positions of four hall sensors are illustrated in fig. 9 as an example, and the positions of the hall sensors are fixed. The spacing between each hall sensor may be the same or different. The four hall sensors are respectively a hall sensor S1, a hall sensor S2, a hall sensor S3 and a hall sensor S4. The center point between the hall sensor S2 and the hall sensor S3 is taken as a reference point O, the distance between the hall sensor S1 and the hall sensor S2 is a, the distance between the hall sensor S2 and the reference point O is b, the distance between the hall sensor S3 and the reference point O is c, and the distance between the hall sensor S3 and the hall sensor S4 is d. For example, the reference point O is represented by a negative number on the left side and a positive number on the right side to distinguish the positions of the different hall sensors. For example, a may be-9.5 mm, b may be-4.5 mm, c may be 4.5mm, and d may be 9.5 mm.
In the process that the driving part drives the telescopic display screen to contract or extend along the target direction, the magnetic parameters of the magnetic part can be acquired in real time, for example, the magnetic parameters can be magnetic field intensity, magnetic flux density and the like. According to the corresponding relation between the magnetic parameters and the position information stored in advance, the position information corresponding to the currently acquired magnetic parameters can be matched. The magnetic parameters may include magnetic flux density, etc.
For example, in an embodiment, the acquiring the magnetic parameters of the magnetic member during the process that the driving member drives the retractable display screen to perform the retractable movement along the target direction in 204 may include:
the driving mechanism is controlled to drive the driving piece to rotate spirally, and the driving piece drives the telescopic display screen to do telescopic motion along the target direction in the spiral rotating process;
and in the process of performing telescopic motion on the telescopic display screen along the target direction, controlling the plurality of Hall sensors to acquire the magnetic flux density of the magnetic part in the spiral rotation process along with the driving part.
For example, actuating mechanism can drive the driving piece spiral and rotate, and when driving the driving piece spiral and rotating, can drive the motion of second casing, simultaneously, can also drive the telescopic display screen and carry out concertina movement when driving the driving piece spiral and rotating, can drive the telescopic display screen and carry out shrink or extension movement when driving the driving piece spiral and rotating. If drive the telescopic display screen when the driving piece spiral rotates and carry out the motion of contracting, then the second casing also moves to the direction that the telescopic display screen contracts, if drive the telescopic display screen when the driving piece spiral rotates and extend the motion, then the second casing also moves to the direction that the telescopic display screen extends.
205. And matching the acquired magnetic flux density with a target magnetic flux density curve to obtain the position of the magnetic part corresponding to the magnetic flux density.
For example, in the process that the driving part drives the telescopic display screen to perform telescopic motion along the target direction, the hall sensors can be used for acquiring the magnetic flux density of the magnetic part in real time, and the magnetic flux density acquired by each hall sensor can change along with the change of the position of the magnetic part.
It should be noted that the hall sensor may be a three-axis hall sensor, and the three axes may be an X axis, a Y axis, and a Z axis. A target magnetic flux density curve is stored in advance, and the target magnetic flux density curve includes a first curve, which may be a corresponding curve of the position of the magnetic member to the magnetic flux density of the X axis, and a second curve, which may be a corresponding curve of the position of the magnetic member to the magnetic flux density of the Z axis. The two curves are stored in advance as reference curves for subsequent use.
Referring to fig. 10, fig. 10 is a schematic diagram of a target magnetic flux density curve provided in the embodiment of the present application. The abscissa is the position of the magnetic member with respect to the reference point O, and the ordinate is the X-axis magnetic flux density and the Z-axis magnetic flux density, respectively. It should be noted that the position of the reference point O may be changed, for example, the reference point O is disposed between the hall sensor S1 and the hall sensor S2.
For example, a stepping motor is adopted to drive the driving piece, and a plurality of Hall sensors are matched to position the magnetic piece. Because the step loss phenomenon can occur in the rotating process of the stepping motor, the Hall sensor is required to be used for collecting the magnetic flux density of the magnetic part for auxiliary positioning. In the moving process of the magnetic part, each Hall sensor respectively collects the magnetic flux density of the magnetic part on the X axis and the Z axis, the collected magnetic flux density of the magnetic part on the X axis and the Z axis is matched with a target magnetic flux density curve, and the position of the magnetic part relative to a reference point can be obtained. If the positions of the magnetic members obtained by matching the two curves are different, the average value of the two curves can be obtained, and the average value can be used as the position of the magnetic member relative to the reference point. It will be appreciated that the position of the magnetic member may be considered to be the position of the second housing.
206. And determining the current position information corresponding to the telescopic display screen according to the position of the magnetic piece.
For example, after the acquired magnetic flux density is matched with the target magnetic flux density curve and the position of the magnetic member corresponding to the magnetic flux density is obtained, the current position information corresponding to the telescopic display screen can be determined according to the position of the magnetic member. According to the magnetic flux density sampling values of the Hall sensor in the X axis and the Z axis, the sampling values are matched with a target magnetic flux density curve to obtain the position information of the magnetic part, and the expansion position of the telescopic display screen can be fitted by combining the target magnetic flux density curve.
207. And controlling the telescopic display screen to update the display area according to the position information.
For example, after the position information corresponding to the telescopic display screen is obtained, the electronic device may control the telescopic display screen to update the display area in real time according to the position information, and may update the touchable area in real time, where the touchable area and the display area are the same size. Namely, through hall sensor assistance-localization real-time, at the real-time concertina movement's of telescopic display screen in-process, can update display area and tangible area in real time. For example, the original curled position of the retractable display screen cannot be touched, and after the retractable display screen is subjected to stretching movement, the stretched part can be updated to be touchable.
In the embodiment of the application, the electronic device can acquire the information of the target position from the motion instruction, and can determine the target direction of the telescopic display screen for telescopic motion according to the information of the target position. Then, the electronic equipment controls the driving piece to drive the telescopic display screen to perform telescopic motion along the target direction; in the process that the driving part drives the telescopic display screen to do telescopic motion along the target direction, the magnetic parameters of the magnetic part can be collected. Then, matching the acquired magnetic flux density with a target magnetic flux density curve to obtain the position of the magnetic part corresponding to the magnetic flux density; determining position information corresponding to the telescopic display screen according to the position of the magnetic piece; and controlling the telescopic display screen to update the display area according to the position information. In the process of performing telescopic motion on the telescopic display screen, the position of the telescopic display screen can be directly determined according to the collected magnetic parameters of the magnetic part, and the telescopic display screen can be positioned. Therefore, the positioning accuracy of the electronic equipment can be improved.
Referring to fig. 11, fig. 11 is a third flowchart illustrating an apparatus control method according to an embodiment of the present disclosure. The device control method can be applied to electronic equipment, and the electronic equipment can comprise a telescopic display screen. The flow of the device control method may include:
301. and acquiring the motion instruction, and determining the information of the target position from the motion instruction.
The specific implementation of step 301 can refer to the embodiment of step 101, and is not described herein again.
302. And controlling the telescopic display screen to perform corresponding telescopic motion according to the information of the target position.
The specific implementation of step 302 can refer to the embodiment of step 102, and is not described herein again.
303. And collecting parameter information of the telescopic display screen in the telescopic motion process.
The specific implementation of step 303 can refer to the embodiment of step 103, and is not described herein again.
304. And determining the position information corresponding to the telescopic display screen according to the parameter information.
The specific implementation of step 304 can refer to the embodiment of step 104, and is not described herein again.
305. And controlling the telescopic display screen to update the display area according to the position information.
The specific implementation of step 305 can refer to the embodiment of step 105, which is not described herein again.
306. And if the telescopic movement time of the telescopic display screen is greater than or equal to the first preset time, controlling the telescopic display screen to stop telescopic movement.
For example, after the information of the target position is obtained, the target direction and the movement distance of the telescopic movement of the telescopic display screen can be correspondingly obtained, so that the movement direction and the movement distance of the magnetic member can also be obtained, the number of turns of the motor can be converted according to the movement distance of the telescopic display screen or the movement distance of the magnetic member, the theoretical rotation time of the motor can be obtained by dividing the number of turns of the motor by the theoretical rotation speed of the motor according to the theoretical rotation speed and the number of turns of the motor, and the theoretical rotation time of the motor is multiplied by a preset ratio to be used as the first preset time. Wherein the preset ratio is greater than 1, such as the preset ratio may be 1.5.
It should be noted that, in the motor rotation in-process, the motor can take place to lose the step phenomenon when rotating very fast, can take place to skid when taking place to lose the step, the system probably thinks the motor still normally rotates, under the condition that does not have hall sensor to gather magnetic flux density, the system does not know the present telescopic motion's of telescopic display screen position this moment, after setting up hall sensor, gather magnetic flux density through hall sensor, just can determine the position that magnetic part is located, and then determine telescopic display screen telescopic motion's position, so that whether arrive the target location in the affirmation. The movement time of the motor is set to be larger than the theoretical rotation time, so that a certain time margin is reserved when the motor loses steps.
If the telescopic display screen does not reach the target position when the telescopic movement time of the telescopic display screen is greater than or equal to the first preset time in the telescopic movement process, the motor is controlled to stop rotating at the moment when the motor is abnormal, and correspondingly, the telescopic display screen also stops telescopic movement.
307. If the distance between the telescopic display screen and the target position is smaller than or equal to the preset distance, reducing the telescopic movement speed of the telescopic display screen to the preset speed, and reducing the residual telescopic movement time of the telescopic display screen to second preset time, wherein the second preset time is smaller than the first preset time.
For example, if the distance between the retractable display screen and the target position is less than or equal to the preset distance, the retractable display screen is considered to be close to the target position at the moment, for example, the distance is 0.4mm away from the target position, because the retractable display screen is close to the target position, the retractable movement speed of the retractable display screen is reduced to the preset speed, for example, the retractable movement speed of the retractable display screen can be reduced by reducing the rotation speed of the motor, after the rotation speed of the motor is reduced, a step loss phenomenon does not occur in the rotation process of the motor at the moment, so that a time margin is not needed any more, the remaining time of the rotation of the motor can be reduced to a second preset time, the second preset time is less than the first preset time, and the second preset time is the theoretical rotation time of the motor during subsequent rotation. It can be understood that the theoretical rotation time of the motor can be converted according to the distance between the current position and the target position of the telescopic display screen.
If the motor is close to the target position and still rotates according to the remaining time in the original first preset time, the telescopic display screen can be caused to exceed the target position, and the problem that the motor cannot stop when moving to the target position due to the positioning error of the Hall sensor can be avoided by reducing the rotating speed of the motor and adjusting the rotating time, so that the first shell and the second shell are prevented from colliding. Therefore, the positioning assistance is carried out by using a plurality of Hall sensors, and the positioning error of the Hall sensors is restrained by adjusting the rotation time of the motor. In addition, the motor can be controlled to stop rotating at any position by adjusting the rotating time of the motor.
308. And if the telescopic display screen telescopically moves to the target position, controlling the telescopic display screen to stop the telescopic movement.
For example, if the retractable display screen moves to the target position in a retractable manner, the retractable display screen can be controlled to stop the retractable movement at this time, specifically, the motor can be controlled to stop rotating, and after the motor stops rotating, the motor cannot drive the electric part to perform spiral movement, so that the retractable display screen also stops the retractable movement correspondingly.
309. And if the telescopic display screen does not move to the target position in a telescopic mode and the telescopic movement time is longer than or equal to the first preset time, controlling the telescopic display screen to stop the telescopic movement.
For example, if the telescopic display screen does not telescopically move to the target position, and the telescopic movement time is greater than or equal to a first preset time, that is, the telescopic movement time reaches the first preset time, which indicates that the motor is abnormal, the motor is controlled to stop rotating at this time, and after the motor stops rotating, the motor cannot drive the electric part to spirally move, so that the telescopic display screen also correspondingly stops telescopic movement, so as to solve the abnormal problem of the motor.
It can be understood that in the embodiment of the application, in the process of the telescopic movement of the telescopic display screen, the magnetic flux density of the magnetic member is collected in real time through the hall sensor, and the position information of the telescopic display screen can be acquired. If the telescopic movement time of the telescopic display screen is greater than or equal to the first preset time, the telescopic display screen is controlled to stop telescopic movement, so that the abnormal problem of the motor is conveniently solved. If the distance between the telescopic display screen and the target position is smaller than or equal to the preset distance, the telescopic movement speed of the telescopic display screen is reduced to the preset speed, the residual telescopic movement time of the telescopic display screen is reduced to second preset time, the second preset time is smaller than the first preset time, positioning assistance is carried out by using a plurality of Hall sensors, and the positioning error of the Hall sensors is inhibited by adjusting the rotation time of the motor, so that the positioning precision of the electronic equipment is improved. In addition, the motor can be controlled to stop rotating at any position by adjusting the rotating time of the motor. If the telescopic display screen telescopically moves to the target position, controlling the telescopic display screen to stop telescopic movement; if the telescopic display screen does not move to the target position in a telescopic mode, and the telescopic movement time is longer than or equal to first preset time, the telescopic display screen is controlled to stop telescopic movement, so that the abnormal problem of the motor can be conveniently solved.
