Patent Description:
With development of communication technologies, electronic devices such as smart phones are becoming increasingly popular. Electronic devices tend to be flat with serious homogeneity. With increasingly diversified functions of electronic devices, an overall structure of the electronic devices has been unable to meet needs of different users.

<CIT> discloses an electronic apparatus control method and electronic apparatus. The electronic apparatus control method is applicable to an electronic apparatus having a flexible screen. The method includes: acquiring a press parameter with respect to a motor drive switch; and controlling, according to the press parameter, a motor to rotate to extend or retract the flexible screen. The method is employed to control extension and retraction of a flexible screen. Specifically, the electronic apparatus includes a flexible screen wound around a hollow winding tube. One end of the winding tube can be inserted into the battery, the other end of the winding tube can be installed motor. The flexible screen can be expanded or contracted by driving a motor to rotate.

<CIT> provides a rollable mobile terminal including a flexible display deformable to be rolled. The terminal includes: a body configured to accommodate various components, the flexible display being configured to be extended from or retracted into the body; and a controller detecting a relative disposition between the display and a user based on a detected extension direction of the display, the controller controlling a content to be oriented on the display in accordance with the detected disposition. Specifically, the mobile terminal has a display region for displaying a screen, and the display region can extend or reduce an externally exposed region by a rolling a deformable display unit. The mobile terminal further includes a display unit configured to be accommodated in the body in a first state or to be externally exposed from the body part in a second state. When an external force is applied to the flexible display unit, the flexible display unit may transition to the second state such that the flexible display unit is deformed into the flat state or into a more curved state.

<CIT> discloses a display control method of an electronic device. The electronic device includes a shell, a rotating mechanism, a driving mechanism, and a flexible display screen. The rotating mechanism and the driving mechanism are accommodated in the shell, and the flexible display screen is wound and connected with the rotating mechanism. A nonopaque area is arranged on the shell, and the part of the flexible display screen corresponding to the nonopaque area forms a first display area of the electronic device. The display control method includes: controlling the driving mechanism to drive the rotating mechanism to rotate towards a corresponding direction in response to a corresponding control signal, so that the flexible display screen is gradually wound and accommodated in the shell or extends from the shell along with the rotation of the rotating mechanism; controlling the first display area and the second display area of the flexible display screen extending from the shell to carry out a corresponding display according to the length of the flexible display screen extending from the shell. The display control method also provides an electronic device. The display control method can effectively increase the screen display size while ensuring that the electronic device is convenient to carry. Specifically, the rotating mechanism disclosed in <CIT> is a rotating drum rotatably coupled to an end surface of the housing that is perpendicular to an extending direction of the rotating cylinder. The flexible display screen is wound and connected to the outer wall of the rotating drum, and the motor of the driving mechanism is connected with the rotating drum to drive the rotating drum to rotate in different directions by changing the rotating direction. The controller is electrically connected to the driving mechanism and configured to control the driving mechanism to drive the rotating mechanism to rotate, so that the flexible display screen is gradually wound up as the rotating structure rotates.

Embodiments of the present disclosure provide an electronic device, which is capable of improving diversity of electronic devices.

The present disclosure provides an electronic device. The electronic device includes a main body, a rotating member, a flexible display screen and a flexible circuit board. The main body has a pillar shape, and an outer periphery of the main body has a groove provided thereon. The rotating member is sleeved on an outside of the main body. The flexible display screen has an end connected to the rotating member, and the rotating member is configured to drive the flexible display screen to be wound or unfolded relative to the rotating member. The flexible circuit board is connected to the flexible display screen. When the flexible display screen is unfolded, the flexible circuit board is unfolded along with the flexible display screen, and when the flexible display screen is wound, the flexible circuit board is wound into the groove of the second portion along with the flexible display screen. The electronic device is characterized in that the main body includes a first portion located at a first end and a second portion located at a second end, the first portion having a cross-sectional area greater than a cross-sectional area of the second portion, and the groove being provided in the second portion.

The first portion having the cross-sectional area greater than that of the second portion means that the first portion has a diameter greater than that of the second portion. When the rotating member is sleeved on an outer periphery of the housing, a space between the first portion and the rotating member is smaller than a space between the second portion and the rotating member. An extra part of the space between the second portion and the rotating member compared to the space between the first portion and the rotating member may be used for mounting other components of the electronic device. For example, a package of a flexible circuit board can be mounted on the second portion. In this way, a space between the main body and the rotating member may be effectively utilized, thereby facilitating mounting of other functional parts of the electronic device.

Referring to <FIG> is a schematic structural diagram of a main body of an electronic device according to an embodiment of the present disclosure. The main body <NUM> can have a shape of a cylinder, a cuboid, a polyhedron, or the like. That is, the main body <NUM> can have a cross-sectional area in various shapes such as a circle, a rectangle, a square, or a polygon. In an embodiment of the present disclosure, a specific shape of the cross-sectional area of the main body <NUM> is not specifically limited. In order to illustrate the embodiments of the present disclosure, unless otherwise specified, the main body <NUM> may be assumed to be a cylindrical body according to an embodiment of the present disclosure.

The main body <NUM> has a first end 10A and a second end 10B that are opposite to each other. In an embodiment of the present disclosure, directions pointed by the first end 10A and the second end 10B are interchangeable. In order to illustrate an embodiment of the present disclosure, unless otherwise specified in the present disclosure, the first end 10A generally refers to an upper end of the main body <NUM>, and the second end 10B refers to a lower end of the main body <NUM>. The main body <NUM> may include a plurality of portions. Specifically, the main body <NUM> may include one portion, two portions, three portions, or more portions. In an embodiment of the present disclosure, the number of the portions of the main body <NUM> is not limited herein.

The main body <NUM> includes a first portion <NUM> and a second portion <NUM>. The first portion <NUM> is located at the first end 10A of the main body <NUM>. The second portion <NUM> is located at the second end 10B of the main body <NUM>. The first portion <NUM> has a cross-sectional area greater than that of the second portion <NUM>. It is to be noted that the first portion <NUM> having the cross-sectional area greater than that of the second portion <NUM> means that the first portion <NUM> has a diameter greater than that of the second portion <NUM>. When the rotating member <NUM> is sleeved on an outer periphery of the housing <NUM>, a space between the first portion <NUM> and the rotating member <NUM> is smaller than a space between the second portion <NUM> and the rotating member <NUM>. An extra part of the space between the second portion <NUM> and the rotating member <NUM> compared to the space between the first portion <NUM> and the rotating member <NUM> may be used for mounting other components of the electronic device <NUM>. For example, a package <NUM> of a flexible circuit board <NUM> can be mounted on the second portion <NUM>. In this way, a space between the main body <NUM> and the rotating member <NUM> may be effectively utilized, thereby facilitating mounting of other functional parts of the electronic device <NUM>.

Referring to <FIG> is another schematic structural diagram of a main body of an electronic device according to an embodiment of the present disclosure. It is to be noted that the package <NUM> of the flexible circuit board <NUM> has an outer diameter identical to that of the first portion <NUM>. Alternatively, the package <NUM> of the flexible circuit board <NUM> can have an outer diameter different from that of the first portion <NUM>. It can be understood that the package <NUM> of the flexible circuit board <NUM> provided on the second portion <NUM> can be provided in various manners on the second portion <NUM> without interfering with rotation of the rotating member <NUM>.

Also referring to <FIG> is yet another schematic structural diagram of a main body of an electronic device according to an embodiment of the present disclosure. The main body <NUM> has a groove <NUM> provided thereon. The groove <NUM> can be configured to place the flexible circuit board <NUM>. It is to be noted that the groove <NUM> can be an annular groove <NUM>, or a rectangular groove <NUM>, or the like. A specific shape of the groove <NUM> is not limited in an embodiment of the present disclosure. The flexible display screen <NUM> needs to be unfolded or wound by the rotating member <NUM> to change a display area of the flexible display screen <NUM>. During unfolding or winding of the flexible display screen <NUM>, the flexible circuit board <NUM> and the flexible display screen <NUM> need to keep energized to provide a display function. Consequently, arranging the flexible circuit board <NUM> in the groove <NUM> can enable the flexible circuit board <NUM> to be unfolded or wound into the groove <NUM> during unfolding or winding of the flexible display screen <NUM>. Such an arrangement not only ensures that the flexible display screen <NUM> is maintained to be connected to the flexible circuit board <NUM>, but also ensures that the flexible circuit board <NUM> is not broken when being pulled. It can be understood that, in an embodiment of the present disclosure, the groove <NUM> being provided as an annular groove <NUM> can facilitate processing. Also, providing the flexible circuit board <NUM> in the annular groove <NUM> with no obtuse angle in the flexible circuit board <NUM> or the annular groove <NUM> can prevent the flexible circuit board <NUM> from being easily scratched by the obtuse angle while better protecting the flexible circuit board <NUM>.

It is to be noted that one, two or event more grooves <NUM> can be provided. A specific number of grooves <NUM> is not specifically limited in the embodiments of the present disclosure. Alternatively, the groove <NUM> can also be configured to place other functional parts, for example, an under-screen fingerprint module is arranged in the groove <NUM>.

The second portion <NUM> includes a first mounting housing <NUM> and a second mounting housing <NUM>. The first mounting housing <NUM> and the second mounting housing <NUM> are matched and fixed to form the second portion <NUM>. The first mounting housing <NUM> and the first portion <NUM> are formed into one piece. It is to be noted that the first mounting housing <NUM> and the second mounting housing <NUM> can be fixedly connected by a fixing thread. The first mounting housing <NUM> and the second mounting housing <NUM> can also be fixedly connected by snap-fitting. Alternatively, the first mounting housing <NUM> and the second mounting housing <NUM> can also be matched and fixed in other manners. In an embodiment of the present disclosure, a through hole <NUM> is further formed between the first mounting housing <NUM> and the second mounting housing <NUM>. The through hole <NUM> can allow a connecting plate <NUM> to pass through. In an embodiment of the present disclosure, the first mounting housing <NUM> and the second mounting housing <NUM> are matched and fixed to form the second portion <NUM>, thereby facilitating receiving functional parts in a receiving space formed in the second portion <NUM>.

It is to be noted that the first mounting housing <NUM> and the second mounting housing <NUM> can be formed into one piece, and the first portion <NUM> and the second portion <NUM> can also be formed into one piece.

Each of the first portion <NUM> and the second portion <NUM> of the main body <NUM> is provided with a receiving space therein. A first receiving space is provided inside the first portion <NUM>. The first receiving space may receive a battery. Alternatively, the first receiving space is not limited to receiving the battery, and may also receive other functional components, for example, a camera <NUM>, etc. A second receiving space can receive a circuit board <NUM>. Alternatively, the second receiving space is not limited to receiving the circuit board <NUM>, and may also receive other functional parts, for example, the under-screen fingerprint module. In an embodiment of the present disclosure, specific functional parts received in the first receiving space and the second receiving space are not specifically limited.

Referring to <FIG> is a schematic structural diagram of a transmission mechanism of an electronic device according to an embodiment of the present disclosure. The transmission mechanism <NUM> includes a drive motor <NUM> and a gear set <NUM>. The drive motor <NUM> is configured to drive the gear set <NUM> to move. The gear set <NUM> is configured to drive the rotating member <NUM> to rotate.

In some embodiments, the drive motor <NUM> is fixedly connected to the main body <NUM>. The drive motor <NUM> is fixedly connected to the gear set <NUM>. It can be understood that the drive motor <NUM> may be fixed to the main body <NUM> or the gear set <NUM> by a threaded connection. Alternatively, the drive motor <NUM> can also be fixed to the main body <NUM> or the gear set <NUM> in other manners, for example, by snap-fitting. Other manners of fixation will not be described in detail in an embodiment of the present disclosure.

In some embodiments, the drive motor <NUM> may be fixed to the main body <NUM> by a fixing portion <NUM>. Specifically, the fixing portion <NUM> includes a bayonet <NUM> and a mounting plate <NUM>. The mounting plate <NUM> may be located on two sides of the bayonet <NUM>. A shape of the bayonet <NUM> may match a shape of an outer periphery of the drive motor <NUM>. The bayonet <NUM> is used for stopping the drive motor <NUM>. The mounting plate <NUM> is fixedly connected to the main body <NUM>. The drive motor <NUM> securely stops the electronic device <NUM> by the bayonet <NUM>, and then the mounting plate <NUM> is fixedly connected to the main body <NUM> by a screw rod. In this manner, the drive motor <NUM> is fixed on the main body <NUM>, and such a manner of fixed connection makes fixation more firmly.

In some embodiments, the drive motor <NUM> is disposed on an outer periphery of the second portion <NUM>, and is located between the groove <NUM> and the gear set <NUM>. The drive motor <NUM> is arranged between the groove <NUM> and the gear set <NUM>, resulting in a small distance between the drive motor <NUM> and the gear set <NUM>, so that the drive motor <NUM> is allowed to occupy a space inside the electronic device <NUM> as small as possible.

It is to be noted that the drive motor <NUM> can include one drive motor <NUM>, two drive motors <NUM>, or even more drive motors <NUM>. There is no specific limit on the number of drive motors <NUM> in an embodiment of the present disclosure.

Referring to <FIG> is a schematic structural diagram of a gear set of a transmission mechanism according to an embodiment of the present disclosure. The gear set <NUM> includes a first gear <NUM> and a second gear <NUM>. The first gear <NUM> is engaged with the second gear <NUM>. The first gear <NUM> is a planetary gear. The second gear <NUM> is an internal gear. The first gear <NUM> has a diameter smaller than that of the second gear <NUM>. The first gear <NUM> is fixedly connected to the drive motor <NUM>. The second gear <NUM> is fixedly connected to the rotating member <NUM>. The gear set <NUM> formed by two gears is driven by the drive motor <NUM> to drive the rotating member <NUM> to rotate. Since a small gear drives a large gear, torque can be increased. In this way, driving of the rotating member <NUM> by the gear set <NUM> can be achieved in a case that the drive motor <NUM> is as small as possible and occupies a small space.

Specifically, the first gear <NUM> is a planetary gear, and the second gear <NUM> is an internal gear. Gear teeth of the planetary gear are engaged with an inside of the internal gear. An outer periphery of the internal gear is fixedly connected to the rotating member <NUM>. In an embodiment of the present disclosure, the first gear <NUM> is a planetary gear, and the second gear <NUM> is an internal gear. In this way, a movement of the planetary gear drives the internal gear to move, and the internal gear is fixedly connected to the rotating member <NUM>, thereby driving the rotating member <NUM> to complete rotation.

Referring to <FIG> is a schematic structural diagram of a rotating member of an electronic device according to an embodiment of the present disclosure. The rotating member <NUM> is of a cylindrical shape. Alternatively, the rotating member <NUM> can also have other shapes, such as a rectangle, etc. That is, the rotating member <NUM> can be a sleeve having a cross-sectional area of being a circle, rectangle, square, polygon, etc. A specific shape of the rotating member <NUM> will not be described in detail in the present disclosure.

In some embodiments, one, two, three, or even more rotating members <NUM> can be provided. In an embodiment of the present disclosure, a specific number of the rotating members <NUM> is not limited. The rotating member <NUM> includes a first sub-rotating member <NUM> and a second sub-rotating member <NUM>. The first sub-rotating member <NUM> and the second sub-rotating member <NUM> move independently. It can be understood that the first sub-rotating member <NUM> can be mounted with an independent flexible display screen <NUM>, and the second sub-rotating member <NUM> is mounted with an independent flexible display screen <NUM>. In this way, split-screen display of the electronic device <NUM> can be achieved by driving the first sub-rotating member <NUM> and the second sub-rotating member <NUM> correspondingly.

A specific application manner may be that, for example, when the electronic device <NUM> does not check too much information, only one of the sub-rotating members <NUM>, <NUM> needs to be rotated out, in order to unfold one flexible display screen <NUM> for displaying a picture. For example, when time or information needs to be checked only, only one flexible display screen <NUM> needs to be unfolded by one rotating member <NUM> for display. When a large area of a display region is required, the first sub-rotating member <NUM> and the second sub-rotating member <NUM> are rotated together, so that the flexible display screens <NUM> mounted on the first sub-rotating member <NUM> and the second sub-rotating member <NUM> are unfolded together to display a picture together. In an embodiment of the present disclosure, the rotating members <NUM> are rotated out one by one to implement the split-screen display of the electronic device <NUM>. Moreover, in this manner, the flexible display screen <NUM> can adjust a size of the display region on left and right sides, and can also adjust a size of the display region on upper and lower ends. The use of the split-screen display allows a user to adjust the display area of the flexible display screen <NUM> flexibly as needed when using the electronic device <NUM>.

In some embodiments, the first sub-rotating member <NUM> and the second sub-rotating member <NUM> are rotated in opposite directions. In this way, the flexible display screen <NUM> can be driven to be unfolded or wound in opposite directions. It is to be noted that the first sub-rotating member <NUM> and the second sub-rotating member <NUM> moving in the opposite directions can enable the flexible display screen <NUM> to be displayed in opposite directions after the flexible display screen <NUM> is divided into two screens. In this way, it may be very convenient for multiple users to use the electronic device <NUM>. For example, two people may sit face to face, watching a video with the electronic device <NUM> according to an embodiment of the present disclosure. When the two people sit and watch the video together, since the screen is small, the two people need to sit close to each other to watch the video. In this event, one of them tends to be farther away from the electronic device <NUM> when watching the video, which lowers viewing comfort. However, with the electronic device <NUM> according to an embodiment of the present disclosure, two people may sit opposite to each other, and each may watch one flexible display screen <NUM>. The electronic device <NUM> according to an embodiment of the present disclosure may be more convenient to use in certain scenarios.

In some embodiments, the first sub-rotating member <NUM> and the second sub-rotating member <NUM> may be arranged symmetrically. In a case that the first sub-rotating member <NUM> and the second sub-rotating member <NUM> are each provided with one flexible display screen <NUM>, the flexible display screen <NUM> can also be arranged symmetrically. In this way, the electronic device <NUM> can form two split screens having the same screen size.

Alternatively, a length of the first sub-rotating member <NUM> can be changed to "be greater than a length of the second sub-rotating member <NUM>, or smaller than the length of the second sub-rotating member <NUM>". In the case that the first sub-rotating member <NUM> and the second sub-rotating member <NUM> are each provided with one flexible display screen <NUM>, the two flexible display screens <NUM> can be formed with different mounting areas. In this way, the electronic device <NUM> may form two split screens of different sizes.

It can be understood that three, four or more rotating members <NUM> can be provided, and the specific number of the rotating members <NUM> is not limited according to an embodiment of the present disclosure. That is, one, two, three, or even more split screens can be formed.

The shape of the rotating member <NUM> can be a cylinder, a cuboid, a polyhedron, and the like. That is, the cross-sectional area of the rotating member <NUM> may be in various shapes such as a circle, a rectangle, a square, and a polygon. In an embodiment of the present disclosure, a specific shape of the cross-sectional area of the rotating member <NUM> is not specifically limited. In order to illustrate the embodiments of the present disclosure, unless otherwise specified, the rotating member <NUM> may be assumed to be cylindrical according to the embodiments of the present disclosure.

A gap is provided between the rotating member <NUM> and the main body <NUM>. Other components of the electronic device <NUM> can be mounted in the gap. Components mounted in the gap are not limited according to the embodiments of the present disclosure. It can be understood that the components mounted in the gap and the main body <NUM> cannot interfere with the rotating member <NUM>, so as to ensure that the rotating member <NUM> can rotate smoothly.

In some embodiments, a first sub-drive motor <NUM> is provided in the first portion <NUM> and a second sub-drive motor <NUM> is provided in the second portion <NUM>. Alternatively, mounting positions of the first drive motor <NUM> and the second drive motor <NUM> can be interchangeable. The embodiments of the present disclosure are not limited to any specific example thereof.

Referring again to <FIG>, the flexible display screen <NUM> can be mounted in the housing <NUM>, can be received in the housing <NUM>, or can extend from an inside of the housing <NUM> to an outside of the housing <NUM>. The flexible display screen <NUM> can display a picture. The flexible display screen <NUM> can display the picture inside the housing <NUM>. The flexible display screen <NUM> can also display the picture outside the housing <NUM>.

The flexible display screen <NUM> can be made of a flexible material. The flexible display screen <NUM> can be deformable. For example, the flexible display screen <NUM> can be bent, curved, and the like. The flexible display screen <NUM> can be received in the housing <NUM>, as illustrated in <FIG>. One end of the flexible display screen <NUM> may be located outside the electronic device <NUM>, or one end of the flexible display screen <NUM> may be located on the housing <NUM> of the electronic device <NUM>, and the other end of the flexible display screen <NUM> may be fixed inside the housing <NUM>.

The flexible display screen <NUM> can be a touch screen display incorporating an electrode layer of a conductive capacitive touch sensor or other touch sensor parts (for example, a resistive touch sensor part, an acoustic touch sensor part, a force-based touch sensor part, a light-based touch sensor part, etc.), or can be a non-touch flexible display screen <NUM>. Electrodes of the capacitive touch screen can be formed by an indium tin oxide pad or an array of other transparent conductive structures.

In some embodiments, when the flexible display screen <NUM> is received in the housing <NUM>, the flexible display screen <NUM> can be displayed through a display window <NUM> on the housing <NUM>. For example, when a part of the flexible display screen <NUM> is located at a position of the display window <NUM>, the flexible display screen <NUM> may be adjacent to a side portion 50C of the housing <NUM> at the position of the display window <NUM>, or may be far away from the side portion 50C of the housing <NUM> at the position of the display window <NUM>. It is to be noted that when the flexible display screen <NUM> is received in the housing <NUM>, the flexible display screen <NUM> may not be displayed, and other displays may be set at the position of the display window <NUM> for display.

Referring to <FIG> is another schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device <NUM> further includes an end cover <NUM>. The end cover <NUM> is configured to fix the drive motor <NUM> and to fix the first mounting housing <NUM> and the second mounting housing <NUM>. In some embodiments, the end cover <NUM> includes a bottom plate <NUM> and a mounting portion <NUM>. The bottom plate <NUM> is fixed at an end portion of the second end 10B. The mounting portion <NUM> extends from the bottom plate <NUM> to the outer periphery of the second portion <NUM>. The drive motor <NUM> is mounted on the mounting portion <NUM>. According to an embodiment of the present disclosure, the bottom plate <NUM> can be fixedly connected to the first mounting housing <NUM> and the second mounting housing <NUM> through threads, allowing the first mounting housing <NUM> and the second mounting housing <NUM> to be fixed firmly. The mounting portion <NUM> extends from the bottom plate <NUM> to the outer periphery of the second portion <NUM>, thereby providing a mounting base for the drive motor <NUM>. Such an arrangement is more convenient when the drive motor <NUM> is mounted on the outer periphery of the second portion <NUM>. Also, this arrangement ensures that the drive motor <NUM> is firmly mounted. Consequently, the drive motor <NUM> can be more stable when driving the gear set <NUM> to work. That is, the flexible display screen <NUM> may be more smoothly unfolded or wound.

Referring to <FIG> is a schematic structural diagram of an end cover of an electronic device according to an embodiment of the present disclosure. In some embodiments, a fixing opening <NUM> is provided on the bottom plate <NUM>. The fixing opening <NUM> is configured to fix a functional part of the electronic device <NUM>. It is to be noted that the functional part may be the circuit board <NUM>. The circuit board <NUM> is fixed in the fixing opening <NUM> by snap-fitting. Specifically, the fixing opening <NUM> includes a plurality of snapping openings. It can be understood that components to be fastened by each snapping opening can be different. A functional part specifically fastened to each of the plurality of snapping openings is not specifically limited according to the embodiments of the present disclosure.

<FIG> is a partially-enlarged schematic diagram of the electronic device illustrated in <FIG>. Referring to <FIG>, the electronic device <NUM> further includes a fixing cover <NUM> fixed on an end of the bottom plate <NUM> facing away from a first end portion 50A. The fixing cover <NUM> may fix the rotating member <NUM> on the gear set <NUM>. It can be understood that fixedly connecting the rotating member <NUM> to the gear set <NUM> through the fixing cover <NUM> enables the gear set <NUM>, when rotating, to drive the rotating member <NUM> to rotate, thereby driving the flexible display screen <NUM> to be unfolded or wound. Also, using the fixing cover <NUM> to connect the gear set <NUM> with the rotating member <NUM> may facilitate mounting without occupying internal space of the electronic device <NUM>.

In some embodiments, an avoiding notch <NUM> may be provided on the fixing portion <NUM>. The avoiding notch <NUM> may be configured to avoid the connecting plate <NUM>. Providing such avoiding notch on the fixing portion <NUM> may not only reduce an overall weight of the electronic device <NUM>, but also avoid interferences when the connecting plate <NUM> is connecting the circuit board <NUM> with the drive motor <NUM>.

Referring again to <FIG>, the electronic device <NUM> further includes a bracket <NUM>. The bracket <NUM> is disposed at the first end portion 50A of the main body <NUM>. It is to be noted that the bracket <NUM> may be fixed at an end portion of the first end 10A connected to the main body <NUM>. Specifically, the bracket <NUM> may be fixed to the end portion of the first end 10A through a threaded connection. Alternatively, the bracket <NUM> may also be fixed to the end portion of the first end 10A by a threaded connection. It can be understood that a specific mounting manner of the bracket <NUM> and the end portion of the first end 10A is not limited in the embodiments of the present disclosure.

In some embodiments, the camera <NUM> and a universal serial bus (USB) interface <NUM> may be provided on the bracket <NUM>.

The inside of the electronic device <NUM> can be seen from the outside of the electronic device <NUM> through the display window <NUM>.

When the flexible display screen <NUM> is wound into the housing <NUM>, the flexible display screen <NUM> can be displayed in the display window <NUM>. It can be understood that since the display window <NUM> opened on the housing <NUM> is relatively small, when the flexible display screen <NUM> is wound in the housing <NUM>, the flexible display screen <NUM> can display relatively simple information such as time and a short message. Also, when the flexible display screen <NUM> is controlled to be unfolded from the inside of the housing <NUM> to the outside of the housing <NUM>, a sliding operation may be performed in the display window <NUM> to generate a control instruction. According to an embodiment of the present disclosure, the housing <NUM> is opened with the display window <NUM>.

The cross-sectional view of the housing <NUM> taken along the direction B-B or the direction C-C forms at least two sides, including at least one arc-shaped side and at least one straight side. For example, the cross-sectional view of the housing <NUM> taken along the direction B-B or the direction C-C forms two sides, including one arc-shaped side and one straight side that are connected with each other.

In some embodiments, referring to <FIG>, which is a fifth cross-sectional view of a housing of an electronic device illustrated in <FIG> taken along a direction B-B or a direction C-C, the cross-sectional view of the housing <NUM> taken along the direction B-B or the direction C-C may also have other shape.

The housing <NUM> is provided with a button <NUM> on an outer surface of the housing <NUM> close to the second end 10B. The button <NUM> is electrically connected to the circuit board <NUM>. It is to be noted that it can be understood that the button <NUM> can be provided at the first end portion 50A or the second end portion 50B or can be provided at the side portion 50C. It can be understood that the button <NUM> may include a plurality of function buttons <NUM>, such as a sound adjustment button, or a trigger button <NUM>. The embodiments of the present disclosure do not limit a function of the button <NUM> specifically.

The housing <NUM> is provided with a sound hole <NUM> of an earpiece on the outer surface of the housing <NUM> close to the second end 10B. The sound hole <NUM> of the earpiece is arranged at <NUM>°. In view of this, sound signals may be transmitted in multiple directions.

The housing <NUM> is provided with a charging interface <NUM> on a bottom surface of the second end portion 50B of the housing <NUM>. It can be understood that the charging interface <NUM> can also be arranged on a side surface of the second end portion 50B, or on a top surface of the first end portion 50A. It is to be noted that "bottom", "side" and "top" according to the embodiments of the present disclosure are only used to introduce the present disclosure, rather than limiting orientations of the present disclosure.

According to an embodiment of the present disclosure, the side portion 50C of the housing <NUM> further includes an outlet <NUM>. The flexible display screen <NUM> is unfolded or wound from the outlet <NUM>. When the flexible display screen <NUM> is received in the housing <NUM> completely, an edge of the flexible display screen <NUM> will seal the outlet <NUM>.

Referring to <FIG> is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. In some embodiments, the edge of the flexible display screen <NUM> is provided with a flange <NUM>. When the flexible display screen <NUM> is received in the housing <NUM> completely, the flange <NUM> is clamped at the outlet <NUM>, and the flange <NUM> seals the outlet <NUM> simultaneously. It is to be noted that the flange <NUM> can be made of a silicone material, a rubber material, or the like. It should be acknowledged that the material for the flange <NUM> is not limited to the above examples. In an embodiment of the present disclosure, the flange <NUM> may play a limiting role to prevent the edge of the flexible display screen <NUM> from being entangled into the housing <NUM>, thereby ensuring that the flexible display screen <NUM> will be unfolded smoothly when the flexible display screen <NUM> is unfolded again. Also, the flange <NUM> may play a role of sealing the outlet <NUM>, thereby achieving a waterproof and dustproof effect.

In an embodiment of the present disclosure, a driving process of unfolding or winding the flexible display screen <NUM> is as follows. When the flexible display screen <NUM> is unfolded from the inside of the housing <NUM> to the outside of the housing <NUM>, the drive motor <NUM> moves to drive the planetary gear to move. The planetary gear is engaged with an inner gear of the internal gear so as to move the planetary gear. Thus, the planetary gear can drive an inner wheel to move. An outer periphery of the internal gear is connected to the rotating member <NUM>. When the internal gear is moving, the rotating member <NUM> will also move. The rotating member <NUM> is fixedly connected to the flexible circuit board <NUM>. A direction in which the rotating member <NUM> move is a direction in which the flexible circuit board <NUM> faces towards an opening. When the drive motor <NUM> stops moving, the flexible display screen <NUM> also stops continuing to be unfolded. An unfolded portion can be configured to display a screen. When the drive motor <NUM> continues moving, the flexible display screen <NUM> can continue to be unfolded until the flexible display screen <NUM> is unfolded fully to provide a largest display region that the electronic device <NUM> is capable of displaying.

When the flexible display screen <NUM> is wound from the outside of the housing <NUM> into the inside of the housing <NUM>, the drive motor <NUM> can relatively move in a direction in which the flexible display screen <NUM> is unfolded from the inside of the housing <NUM> to the outside of the housing <NUM>. The drive motor <NUM> drives the planetary gear to move. The planetary gear drives the inner wheel to move. The rotating member <NUM> moves accordingly. The rotating member <NUM> is fixedly connected to the flexible circuit board <NUM>. A direction in which the rotating member <NUM> moves is a direction in which the flexible circuit board <NUM> faces towards the outlet <NUM>. When the drive motor <NUM> stops moving, the flexible display screen <NUM> also stops continuing to be wound. When the drive motor <NUM> continues to move, the flexible display screen <NUM> may continue to be wound until the flexible display screen <NUM> is received in the housing <NUM> completely.

In an embodiment of the present disclosure, the main body <NUM> has a groove <NUM> provided therein. The gear set <NUM> is arranged at an end portion of either end of the main body <NUM>. The rotating member <NUM> is sleeved on the outer periphery of the main body <NUM>. The gear set <NUM> is connected to the rotating member <NUM>. The flexible display screen <NUM> is fixedly connected to the rotating member <NUM>. The flexible circuit board <NUM> is arranged in the groove <NUM>. The flexible circuit board <NUM> is electrically connected to the flexible display screen <NUM>. Movement of the gear set <NUM> can drive the rotating member <NUM> to move. The rotating member <NUM> can drive the flexible display screen <NUM> to be unfolded or wounded. The gear set <NUM> may be provided at an end portion of either end of the housing <NUM>. The rotating member <NUM> is sleeved on the outer periphery of the housing <NUM>. The gear set <NUM> is connected to the rotating member <NUM>. The gear set <NUM> drives the rotating member <NUM> to move to achieve flexible unfolding or winding. The display area of the flexible display screen <NUM> may be changed by unfolding and winding of the flexible display screen <NUM>, and thus the user can adjust the area of the display region as required. Also, since the gear set <NUM> is provided at an end portion of one end of the housing <NUM>, a transmission part will not occupy the space inside the housing <NUM>, which facilitates arranging other functional parts in the electronic device <NUM>. In addition, arranging the flexible circuit board <NUM> in the groove <NUM> enables the flexible circuit board <NUM> to be unfolded or wound into the groove <NUM> along with the flexible display screen <NUM> during unfolding or winding of the flexible display screen <NUM>. Such an arrangement not only ensures that the flexible display screen <NUM> is maintained to be connected to the flexible circuit board <NUM>, but also ensures that the flexible circuit board <NUM> will not be broken when being pulled.

It is to be noted that it is possible to wind the flexible display screen <NUM> from the outside of the housing <NUM> to the inside of the housing <NUM> by a reset mechanism instead of the drive motor <NUM>. The embodiments of the present disclosure do not limit a structure of the reset mechanism structure specifically.

In some embodiments, the electronic device <NUM> includes an acoustic device. The acoustic device is configured to transmit or receive a sound signal. The acoustic device is coupled to the processor <NUM>. The processor <NUM> is configured to generate the control instruction based on the received sound signal. It can be understood that when the acoustic device receives a sound signal, the processor <NUM> matches the received sound signal with a preset sound signal to obtain a matching result. If the received sound signal matches the preset sound signal, then the control instruction is generated. The control instruction can control an operation of the transmission mechanism <NUM>. Such a mode of operation is very convenient. In some occasions, the unfolding or winding of the flexible display screen <NUM> is controlled based on the sound signal, facilitating operations.

In some embodiments, with reference to <FIG>, the electronic device <NUM> further includes a trigger button <NUM>. The trigger button <NUM> is coupled to the processor <NUM>. When a signal from the trigger button <NUM> is transmitted to the processor <NUM>, the control instruction is generated. It is to be noted that the trigger button <NUM> may be arranged on the housing <NUM>. When the trigger button <NUM> is pressed, the signal from the trigger button <NUM> is transmitted to the processor <NUM>, which in turn generates the control instruction. Using such a control mode to control the transmission mechanism <NUM> can quickly unfold or wind the flexible display screen <NUM>.

In some embodiments, the sliding operation includes sliding at a preset position in a preset direction. A specific control method may be as follows. For example, the sliding operation is performed in a first direction, and then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member <NUM> to rotate in the first direction. The sliding operation is performed in a second direction, and then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member <NUM> to rotate in the second direction.

In some embodiments, the sliding operation includes sliding in the preset direction after time for contacting at the preset position reaches a threshold. A specific control method may be as follows. A long press is performed on the flexible display screen <NUM>, for example, after a long press of two seconds on the flexible display screen <NUM>, and then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member to rotate in the first direction. The sliding operation is performed in the second direction, and then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member to rotate in the second direction.

The first direction and the second direction may be directions perpendicular to an axial direction of the main body <NUM>. The first direction and the second direction may be opposite to each other. The first direction includes at least one opposite component that is opposite to at least one component of the second direction. It is to be noted that when both the first direction and the second direction are not perpendicular to the axial direction of the main body <NUM>, each of the first direction and the second direction at least includes a component perpendicular to the axial direction of the main body <NUM>. The rotating member <NUM> may rotate towards the component perpendicular to the axial direction of the main body <NUM>.

It is to be noted that when the rotating member <NUM> needs to unfold the flexible display screen <NUM>, the first direction may also be to draw a circle in a direction in which the rotating member <NUM> needs to be rotated. When the rotating member needs to wind the flexible display screen <NUM>, the second direction may be drawing a reverse circle opposite to the first direction.

In some embodiments, the processor <NUM> can be configured to control, based on a sliding distance of the sliding operation, an angle at which the rotating member is rotated with drive of the transmission mechanism <NUM>. The sliding distance can be a distance perpendicular to the axial direction of the main body <NUM>.

In some embodiments, the processor <NUM> can be configured to control, based on a sliding force of the sliding operation, a speed at which the rotating member is rotated with drive of the transmission mechanism <NUM>. The sliding force of the sliding operation can be a force of pressing the flexible display screen <NUM> of the electronic device <NUM>. The sliding force can be detected by a pressure sensor. For example, if the sliding force of the sliding operation is larger than as expected, then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member to rotate at a faster speed. If the sliding force of the sliding operation is smaller than as expected, then the processor <NUM> controls the transmission mechanism <NUM> to drive the rotating member <NUM> to rotate at a slower speed.

It is to be noted that the control instruction is not limited to any example thereof. For example, rotation of a drum is controlled in accordance with gravity, acceleration, acceleration direction, sound control, etc..
