The electronic device and the screen adjusting method of the electronic device provided by the embodiment of the application are described in detail below by means of specific embodiments and application scenes thereof with reference to the accompanying drawings.

Fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present application. As shown in fig. 1, the electronic device includes a housing 10, a center frame 20, a first screen 30, and a second screen 40; the middle frame 20 is movably connected with the shell 10; the middle frame 20 is provided with a rotating shaft 21; a motor 52 is arranged in the shell 10, the motor 52 is in transmission connection with the rotating shaft 21, the first screen 30 is covered on the shell, one end of the second screen 40 is fixedly connected with one end of the middle frame 20, and the other end of the second screen 40 is fixedly connected with the rotating shaft 21;

when the motor 52 rotates, the motor 52 drives the rotating shaft 21 to rotate along the first direction, the second screen 40 is wound on the rotating shaft 21, and the middle frame 20 moves along the direction approaching the housing 10.

Fig. 2 is a schematic structural diagram of an electronic device according to another embodiment of the present application. As shown in fig. 2, the motor 52 and the rotating shaft 21 are connected through a variable-length transmission assembly 51, and when the motor 52 rotates, the length of the transmission assembly 51 becomes shorter, so that the rotating shaft 21 is driven to rotate in a first direction, and the middle frame 20 moves in a direction approaching the housing 10.

The transmission assembly 51 comprises a pulley block and a variable-length transmission piece 511, and the pulley block is connected with the rotating shaft 21 in a matching way through a transmission mechanism (not shown in the figure); one end of the transmission member 511 is connected to the rotation shaft 21, and the other end of the transmission member 511 is connected to the pulley block. When the motor 52 rotates, the motor 52 drives the pulley block to move along the direction approaching the shell 10 through the transmission piece 511, and the pulley block drives the rotating shaft 21 to rotate along the first direction through the transmission mechanism; the length of the transmission 511 becomes short, and the degree of shortening matches the number of turns of the motor 52.

Optionally, the pulley block comprises at least two pulleys, namely a first pulley 512 and a second pulley 513, one end of the transmission member 511 is connected with the rotating shaft 21, and the other end of the transmission member is sequentially wound on the first pulley 512 and the second pulley 513; the second pulley 513 is connected with the rotating shaft 21 in a matching way through a transmission mechanism. When the motor 52 rotates, the motor 52 drives the second pulley 513 to move in a direction approaching the housing 10 through the transmission member 511, and the second pulley 513 drives the rotation shaft 21 to rotate.

In this embodiment, when the motor 52 drives the rotating shaft 21 to rotate along the second direction, the motor 52 drives the pulley block to slide along the direction away from the housing 10 through the transmission member 511, so that the length of the transmission member 511 is increased, and the length is matched with the moving distance of the middle frame 20. Specifically, when the pulley block includes the first pulley 512 and the second pulley 513, the motor 52 drives the second pulley 513 to slide along a direction away from the housing 10 through the transmission member 511, and the second pulley 513 drives the second rotating shaft to rotate through the transmission mechanism. Wherein the second direction is opposite to the first direction.

When the motor 52 drives the rotating shaft 21 to rotate along the first direction, the motor 52 drives the pulley block to slide along the direction close to the shell 10 through the transmission piece 511, so that the pulley block drives the rotating shaft 21 to rotate through the transmission piece 511, and the second screen is wound on the rotating shaft 21. At this time, the length of the transmission 511 becomes short, and the degree of shortening matches the moving distance of the center 20. Specifically, when the pulley block includes the first pulley 512 and the second pulley 513, the motor 52 drives the second pulley 513 to slide along the direction approaching the housing 10 through the transmission member 511, and the second pulley 513 drives the rotating shaft 21 to rotate through the transmission mechanism.

In this embodiment, the motor 52 may be structured as shown in fig. 3. The motor 52 is provided with a rotating shaft, two ends of the rotating shaft on the motor 52 are respectively provided with a transmission head 521 and 522 for connecting with the transmission member 511, and the motor 52 may be further provided with two wires 523 and 524 for connecting the transmission head and a calculation module, wherein the function of the calculation module will be described in detail in the following embodiments.

In one embodiment, the middle frame 20 includes two shafts 21; each rotating shaft 21 is respectively positioned at two sides of the first screen; the motor 52 includes a rotating shaft and driving heads 521 and 522 (shown in fig. 3) disposed at two ends of the rotating shaft, and each driving head drives one side of the rotating shaft 21 to rotate through a driving member 511 connected to each driving head.

In the embodiments shown in fig. 1 and 2 described above, the first screen may be a rigid screen and the second screen may be a flexible screen.

Fig. 4 schematically illustrates a screen state in which the second screen 40 is wound out of the first rotation shaft 21 when the user pulls the middle frame 20 to the left and right sides, respectively. As can be seen from fig. 3, in the case that the middle frame 20 moves in a direction away from the middle frame 20, the left rotary shaft 21 rotates to the left and drives the second pulley 513 through the transmission mechanism with the lower left pulley 513, at this time, the motor 52 releases the transmission member 511 by the rotation of the rotary shaft on the motor 52, so that the length of the transmission member 511 between the transmission member 522 and the first pulley 512 becomes longer. At the same time, the right rotary shaft 21 rotates rightward and drives the second pulley 513 to move rightward through the transmission mechanism with the first pulley 512 at the upper right corner, and at this time, the motor 52 releases the transmission member 511 by the rotation of the rotary shaft on the motor 52, so that the length of the transmission member 511 between the transmission member 521 and the first pulley 512 becomes longer. At this time, the second screen 40 is wound out of the rotation shaft 21, and the screen size of the electronic device becomes large.

Similarly, when the motor 52 rotates to drive the middle frame 20 to move in a direction approaching the housing 10, the first rotating shaft 21 on the left side rotates rightward, and the second pulley 513 is driven to move rightward by the transmission mechanism between the second pulley 513 and the lower left corner, at this time, the motor 52 rotates via the rotating shaft on the motor 52 to enable the transmission head 522 to recover the transmission member 511, so that the length of the transmission member 511 between the transmission head 522 and the first pulley 512 becomes shorter. At the same time, the first rotating shaft 21 on the right side rotates leftwards, and drives the second pulley 513 to move leftwards through the transmission mechanism between the first pulley 512 on the upper right corner, at this time, the motor 52 enables the transmission head 521 to recover the transmission member 511 through the rotation of the rotating shaft on the motor 52, so that the length of the transmission member 511 between the transmission head 521 and the first pulley 512 is shortened. At this time, the second screen 40 is rewound onto the first rotation shaft 21, and the screen size of the electronic device becomes smaller.

In one embodiment, the transmission 511 may be a track that is wound around a rotating shaft on the motor 52. When the motor 52 rotates to make the track wind out of the transmission head on the rotating shaft of the motor 52, the length of the track between the transmission head and the second pulley becomes longer, and the middle frame 20 moves in a direction away from the housing 10; when the motor 52 rotates, the track wraps around the drive head on the shaft of the motor 52, the track length between the drive head and the second pulley becomes shorter, and the center frame 20 moves in a direction approaching the housing 10.

In one embodiment, the motor 52 further includes a computing module that is connected to the motor 52 by wires, as shown in FIG. 3. The calculation module is used for determining a first rotation amount of the rotating shaft on the motor 52 when the second screen 40 is wound out of the rotating shaft 21, calculating a second rotation amount of the rotating shaft on the motor 52 according to the first rotation amount and the first input when the first input of the target screen display size is received, and controlling the rotating shaft on the motor 52 to rotate according to the second rotation amount. Wherein, the first rotation amount and the second rotation amount can be characterized by rotation turns.

Based on the structure of the electronic device in the above embodiment, a user can adjust the screen display size of the electronic device by pulling the middle frame outside the electronic device, and according to the difference of the distances of the user pulling the middle frame, the screen display size of the electronic device can be adjusted at will between the two states that the second screen is not unfolded and is completely unfolded, so that the use experience of the user is improved.

Fig. 5 is a schematic flowchart of a screen adjusting method of an electronic device according to an embodiment of the present application. As shown in fig. 5, the method is applied to the electronic device provided in any of the foregoing embodiments, and includes the following steps:

s502, when the second screen of the electronic device is unfolded, determining the first rotation amount of the rotating shaft on the motor along the third direction.

Wherein the third direction comprises a counterclockwise direction or a clockwise direction. If the movement direction of the middle frame is taken as the horizontal direction, the component of the third direction in the horizontal direction should be consistent with the direction away from the housing.

The first rotation amount may be a first rotation number, for example, when the second screen of the electronic device is unfolded, the rotation shaft on the middle frame moves along a direction away from the housing, and the second pulley fixedly connected with the rotation shaft on the middle frame also moves along with the rotation shaft and drives the rotation shaft on the motor to rotate along a third direction, so that the first rotation number of the rotation shaft on the motor along the third direction can be determined.

S504, a first input to a target screen display size is received.

S506, determining a second rotation amount of the rotating shaft on the motor along a fourth direction according to the first rotation amount and the first input, and controlling the rotating shaft on the motor to rotate according to the second rotation amount.

Wherein the fourth direction is opposite to the third direction, including a clockwise direction or a counterclockwise direction. For example, when the third direction is clockwise, the fourth direction is counterclockwise. By controlling the rotation of the rotating shaft on the motor in a fourth direction opposite to the third direction, the second screen of the electronic device can be wound back onto the first rotating shaft, so that the screen display size of the electronic device is reduced.

In this embodiment of the present application, when the second screen of the electronic device is unfolded, by determining the first rotation amount of the rotation shaft on the motor along the third direction, and when the first input of the target screen display size is received, determining the second rotation amount of the rotation shaft on the motor along the fourth direction (i.e., the direction opposite to the third direction) according to the first rotation amount and the first input, and further controlling the second rotation shaft to rotate according to the second rotation amount, so that the electronic device can controllably shrink the second screen according to the input of the user to the target screen display size, thereby achieving the effect of intelligently shrinking the screen size, and improving the use experience of the user.

In one embodiment, there is a mapping relationship between the amount of rotation of the spindle on the motor and the screen display size of the electronic device. Assuming that the screen display size is smallest when the second screen is fully wound around the rotation axis of the center frame, i.e., the second screen is not unfolded, the screen display size can be characterized as the following formula (1):

when the second screen is wound out of the rotation shaft (i.e., unwound) on the center, the mapping relationship between the rotation amount of the rotation shaft on the motor and the screen display size of the electronic device can be characterized as the following formula (2):

wherein S represents the screen size (i.e. the size of the initial screen) when the second screen is not unfolded, sx represents the screen size when the second screen is wound out of the rotating shaft on the middle frame, a is the length of the initial screen, b is the width of the initial screen, C is the circumference of the rotating shaft on the motor, and Q1 and Q2 are the rotation amounts of the transmission heads at two ends of the rotating shaft on the motor respectively.

Therefore, after determining the first rotation amount of the rotating shaft on the motor along the third direction, according to the above formula (2), an initial screen display size corresponding to the first rotation amount can be calculated, where the initial screen display size is the screen display size corresponding to the state that the second screen is wound out of the rotating shaft on the middle frame.

In one embodiment, the first input comprises: and adjusting the progress bar for determining the display size of the target screen. Based on this, when receiving the first input to the target screen display size, a second input to the electronic device may be received first, where the second input may be a click operation on a specified physical key on the electronic device, a selection operation on a virtual key on the first screen, and so on. And then displaying the progress bar according to the second input and receiving the adjustment operation of the user on the progress bar.

Fig. 6 is an interface schematic diagram of a progress bar provided according to an embodiment of the present application. As shown in fig. 6, the progress bar includes progress nodes, and the user can adjust the progress bar by dialing the progress nodes. The progress node on the progress bar may be located at the rightmost side of the progress bar, i.e., the progress of the progress bar is 100%, before the user adjusts the progress bar. After the user adjusts the progress bar, the electronic device can calculate the progress reduction ratio corresponding to the progress bar according to the position of the progress node on the progress bar. For example, when the progress node is shifted to the middle position on the progress bar, the progress bar corresponds to 50% of the progress, and the progress reduction ratio is 50%.

After the user adjusts the progress bar, the screen scaling of the electronic equipment can be determined according to the adjustment operation, and then the target screen display size of the electronic equipment is calculated according to the initial screen display size and the screen scaling; then, according to the mapping relation represented by the formula (2), determining a second rotation amount corresponding to the display size of the target screen.

The screen scaling of the electronic device may be determined according to a progress reduction scale of the progress bar. Optionally, the screen scaling of the electronic device is equal to the progress reduction of the progress bar. For example, if the progress bar is 100% before the user adjusts the progress bar, 50% after the user adjusts the progress bar, and the progress reduction ratio is 50%, the screen scaling ratio of the electronic device is also 50%.

The determination of the initial screen display size may be performed immediately after S502 is performed, or may be performed after receiving the user' S adjustment operation of the progress bar, which is not limited in this embodiment.
