[0060] The exemplary embodiments will be described in detail below with reference to the drawings. The following description is only exemplary and is not intended to limit the present disclosure. Rather, the following description is intended to explain the exemplary embodiments consistent with the present disclosure, as claimed below.

[0061] In the description of the present disclosure, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship of the user when using the electronic device, and do not limit the present disclosure. Figure One Figure Five In the description of the present disclosure, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate the orientation or positional relationship based on the orientation or positional relationship of the user when using the electronic device, and do not limit the present disclosure.

[0062] Figure One is a structural schematic diagram of an electronic device according to an exemplary embodiment, which comprises:

[0063] The body part 100 comprises a first shell 110 and a first screen 120 mounted on the first shell 110; the first screen 120 is a hard screen;

[0064] The reel part 200 comprises a second shell 210 and a reel 230 located in the second shell 210;

[0065] A second screen, wherein the second screen is a flexible screen 300; the flexible screen 300 comprises a first end fixed on the reel 230 and a second end fixedly connected with the body part 100; wherein the second end is the opposite end of the first end;

[0066] The flexible screen 300 is in a hidden state, the flexible screen 300 is wound on the reel 230, and the second shell 210 and the first shell 110 are located on two sides of the first screen 120 respectively;

[0067] The flexible screen 300 is in an unfolded state, the second shell 210 and the first screen 120 are located on two sides of the flexible screen 300 respectively; the flexible screen 300 and the first shell 110 are located on two sides of the first screen 120.

[0068] In the embodiments of the present disclosure, the electronic device has two screens, i.e. a hard screen and a flexible screen 300. The hard screen covers one face of the first shell 110 and can be exposed on the outer surface of the first shell 110. The flexible screen 300 can be unfolded from the reel 230 as needed to increase the exposed area of the flexible screen 300, presenting the effect of a large screen; or the flexible screen 300 is wound on the reel 230 and is not exposed, and the electronic device is used as a common hard screen device, and various use modes enrich the user experience.

[0069] ​Generally, the body part 100 refers to a component having multiple functions such as communication function, playing function, game function, etc., including but not limited to core components such as central processing unit (CPU), memory, sensor, camera, wireless controller, graphics processor, etc. When the flexible screen 300 is in a hidden state, the body part 100 can be used alone, and the body part 100 is small in size, easy to carry, and has a high frequency of use.

[0070] The electronic device includes but is not limited to a mobile phone, a tablet computer, a notebook computer, a television, a wearable device, etc. When the flexible screen 300 is in a hidden state, the first screen 120 can be used to display information, send messages, play audio and video, and perform simple information processing and applications. The electronic device can be a cuboid display device, for example, a straight mobile phone. When the flexible screen 300 is in an unfolded state, the flexible screen 300 can present a large-screen display effect.

[0071] Optionally, when the flexible screen 300 is in an unfolded state, the display surface of the flexible screen 300 can be oriented to the same side as the display surface of the hard screen. At this time, the application scenarios of the electronic device can include that the flexible screen 300 is a display screen, and the hard screen is an operation screen. For example, the flexible screen 300 displays a video picture, and the hard screen displays controls such as a play key, a pause key, and / or a progress bar of the video. For another example, the flexible screen 300 displays content as a display screen, and the hard screen displays a virtual keyboard for use as a keyboard.

[0072] In another embodiment, the flexible screen 300 and the hard screen display different content information, for example, the flexible screen 300 plays multimedia information, and the hard screen displays a social interface.

[0073] In other optional embodiments, the electronic device further includes a rotating rod located between the flexible screen 300 and the first housing 110 and rotatable relative to the first housing 110. Through rotation of the rotating rod relative to the first housing 110, the flexible screen 300 and the hard screen can have different relative positional relationships. For example, one of the two end portions of the rotating rod is rotatably connected to the first housing 110, and the other end portion is fixed to the flexible screen 300. When the flexible screen 300 is in an unfolded state, the rotating rod can rotate the flexible screen 300 by 180 degrees relative to the hard screen, so that the display surfaces of the flexible screen 300 and the hard screen are opposite. At this time, the flexible screen 300 and the hard screen display different content information, and the electronic device can be used as two independent devices for use by two different users facing each other.

[0074] Therefore, the arrangement of the hard screen and the flexible screen 300 enriches the application scenarios of the electronic device, meets the use requirements of the user at different times, enhances the sense of technology, and improves the user experience.

[0075] Figures One to Four The electronic device structure diagram is shown in the hidden state of the flexible screen 300. Not only the reel 230 is located in the second shell 210, but also the flexible screen 300 wound on the reel 230 is located in the second shell 210, and the second shell 210 has the shielding and protection effect on the flexible screen 300. In the hidden state of the flexible screen 300, the exposed flexible screen 300 cannot be observed, and only the first screen 120 can be observed.

[0076] Figures Five to Eight The electronic device structure diagram is shown in the hidden state of the flexible screen 300. Not only the reel 230 is located in the second shell 210, but also the flexible screen 300 wound on the reel 230 is located in the second shell 210, and the second shell 210 has the shielding and protection effect on the flexible screen 300. In the hidden state of the flexible screen 300, the exposed flexible screen 300 cannot be observed, and only the first screen 120 can be observed.

[0077] In other optional embodiments, the reel part 200 further comprises:

[0078] The bearing 220 is connected at both ends of the reel 230.

[0079] The bearing 220 is provided with a sliding groove 221 on the end face opposite to the flexible screen 300, and the sliding groove 221 is used for guiding the movement of the flexible screen 300, and the side edge of the flexible screen 300 is embedded in the sliding groove 221.

[0080] As shown in Figure Ten , one bearing 220 is arranged at each end of the reel 230, and the bearing 220 is used for supporting the rotation of the reel 230, reducing the friction coefficient of the reel 230, and ensuring the rotation accuracy of the reel 230. When the flexible screen 300 is unwound from the reel 230 or wound on the reel 230, it moves along the sliding groove 221. The sliding groove 221 can control the motion trajectory of the flexible screen 300, and reduce the damage of the screen body caused by the inconsistent motion trajectory of the flexible screen 300 each time it is unwound or wound.

[0081] Non-limitingly, the sliding groove 221 is in a spiral involute shape. As shown in Figure Ten , the starting point of the sliding groove 221 can be the center of the bearing 220, and the sliding groove 221 extends to the edge of the bearing 220 along the circumferential direction of the bearing 220 in a spiral involute trajectory.

[0082] In other optional embodiments, the electronic device further comprises:

[0083] The support sheet 400 is attached to the back of the flexible screen 300, and the two ends are connected to the reel 230 and the first shell 110, respectively.

[0084] The support sheet 400 has a certain supporting effect on the flexible screen 300. Figure Seven ,Figure Ten and Figure Eleven The support sheet 400 is shown as an example located at the back of the flexible screen 300. The flexible screen 300 is attached to the support sheet 400, and the support sheet 400 moves with the flexible screen 300.

[0085] Further, the flexible screen 300 is connected to the reel 230 and the body part 100 through the support sheet 400. Specifically, one end of the support sheet 400 is fixed to the reel 230, and the other end is fixed to the body part 100.

[0086] For example, a first mounting hole 410 can be provided on the support sheet 400, and a second mounting hole can be provided on the reel 230 and the first housing 110. A fastener such as a screw is used to pass through the first mounting hole 410 and the corresponding second mounting hole, thereby achieving the fixation of the support sheet 400 to the reel 230 and the fixation of the support sheet 400 to the first housing 110. In addition, other fixation methods such as adhesion can also be used.

[0087] Without limitation, the material of the support sheet 400 is metal, such as steel, aluminum, or a plastic sheet with high strength, etc.

[0088] In other optional embodiments, the electronic device further comprises a connecting support mechanism 500 located at the back of the flexible screen 300, for supporting the flexible screen 300.

[0089] When the flexible screen 300 is in the hidden state, the connecting support mechanism 500 is hidden between the first housing 110 and the second housing 210.

[0090] When the flexible screen 300 is in the unfolded state, the connecting support mechanism 500 is exposed between the first housing 110 and the second housing 210.

[0091] The connecting support mechanism 500 is used to further improve the support effect on the flexible screen 300. When the flexible screen 300 is in the unfolded state, it will be curved due to its own weight, and cannot present the display interface in a relatively flat state, affecting the user experience. The setting of the connecting support mechanism 500 can reduce the occurrence of this condition. When the flexible screen 300 is in the unfolded state, the connecting support mechanism 500 can provide support through contact with the support sheet 400.

[0092] When the electronic device further comprises the above-mentioned support sheet 400, the connecting support mechanism 500 is located at the back of the support sheet 400, and supports the flexible screen 300 and the support sheet 400 through contact with the support sheet 400.

[0093] In other optional embodiments, the connecting support mechanism 500 comprises:

[0094] At least one folding rod, two ends of the folding rod are rotatably connected to the first housing 110 and the second housing 210 respectively;

[0095] The flexible screen 300 is in a hidden state, and the folding rod is folded;

[0096] The flexible screen 300 is fully unfolded, and the folding rod is unfolded to be a straight rod.

[0097] The folding rod can be folded with the winding of the flexible screen 300, or unfolded with the unfolding of the flexible screen 300. As shown in Figures One to Four When the flexible screen 300 is in a hidden state, the folding rod is folded and stored between the first housing 110 and the second housing 210, and the exposed folding rod cannot be seen from the outside of the electronic device. As shown in Figures Five to Seven , and Figure Eleven When the flexible screen 300 is in an unfolded state, the folding rod is unfolded. At this time, the folding rod is in contact with the support sheet 400, and has a supporting effect on the support sheet 400 and the flexible screen 300.

[0098] When the flexible screen 300 is fully unfolded, the unfolded folding rod has a preset included angle. It can be understood that the preset included angle of the unfolded folding rod is greater than the included angle of the folding rod in the folded state. Optionally, the preset included angle is 30-180°, further, the preset included angle is 90-180°, or 120-180°. For example, the preset included angle of the folding rod when unfolded is 120°, and the included angle of the folding rod when folded is 0°. In addition, the preset included angle of the folding rod when unfolded can also be 110°, 130°, 145°, and when the preset included angle of the folding rod is 180°, the folding rod is a straight rod.

[0099] Generally, the rotatable connection of the folding rod to the first housing 110 or the second housing 210 can be achieved by a pin. Specifically, a pin is installed on the first housing 110 and the second housing 210, and the corresponding end of the folding rod is connected to the pin and can rotate relative to the axis of the pin.

[0100] One or more folding rods can be provided on the electronic device, and two or more folding rods can be provided. When multiple folding rods are provided, the multiple folding rods can be arranged side by side and distributed equidistantly behind the flexible screen 300. As shown in Figures Five to Seven One folding rod is arranged at each of the upper and lower ends of the electronic device.

[0101] In other optional embodiments, the electronic device further comprises a protective layer located behind the folding rod and connected between the first housing and the second housing, and moving with the flexible screen 300, at least for shielding the folding rod or the rotating rod. The protective layer can be made of flexible materials such as fabric, rubber, etc., and can be selected comprehensively considering the decoration and protection.

[0102] In other optional embodiments, the folding rod comprises:

[0103] the connecting piece 530;

[0104] the first connecting rod 510, two ends of the first connecting rod 510 are respectively rotatably connected to the first shell 110 and the connecting piece 530;

[0105] the second connecting rod 520, two ends of the second connecting rod 520 are respectively rotatably connected to the connecting piece 530 and the second shell 210.

[0106] The first connecting rod 510 is rotatably connected to the first shell 110 through the pin 531, and the second connecting rod 520 is also rotatably connected to the second shell 210 through the pin 531. When the flexible screen 300 is in the unfolded state, the first connecting rod 510, the second connecting rod 520 and the connecting piece 530 can all contact the support sheet 400 to play a supporting role.

[0107] The first connecting rod 510 can be installed on the first shell 110 above the support sheet 400, and the second connecting rod 520 can be installed on the second shell 210 above the support sheet 400.

[0108] Alternatively, as shown in Figures Five to Eight and Figure Eleven , wherein, Figure Eight The double-headed arrow in the figure represents the moving direction of the folding rod, and the moving direction of the first connecting rod 510 or the second connecting rod 520 at the corresponding position. The first connecting rod 510 is installed on the first shell 110 outside the support sheet 400, and the second connecting rod 520 is installed on the second shell 210 outside the support sheet 400. This arrangement can provide more installation space for the pin 531, and also reduce the thickness of the first shell 110 and the second shell 210 to a certain extent.

[0109] The connecting piece 530 can be a shaft such as the pin 531. The shaft can be installed at the end of the first connecting rod 510 away from the first shell 110, and the second connecting rod 520 is rotatably connected to the shaft; or the shaft can be installed at the end of the second connecting rod 520 away from the second shell 210, and the first connecting rod 510 is rotatably connected to the shaft.

[0110] Alternatively, as shown in Figures Five to Eight and Figure Eleven , wherein, Figure Eleven The three circles in the figure respectively indicate the positions of the pins 531. The connecting piece 530 comprises a pin seat 532 and pins 531 arranged at both ends of the pin seat 532, the first connecting rod 510 is rotatably connected to one of the pins 531, and the second connecting rod 520 is rotatably connected to the other pin 531.

[0111] The folding rod can be formed by more links hinged to each other in addition to the two links mentioned above, i.e., the first link 510 and the second link 520. The links are generally rigid members, and the material can be metal, plastic, etc.

[0112] In addition, the connecting support mechanism 500 can adopt other structural forms in addition to the structure of the folding rod mentioned above.

[0113] For example, the connecting support mechanism 500 includes one or more support rods, one end of the support rod is rotatably connected to the first shell 110, and the other end is installed on the support sheet 400 and can move along a preset track relative to the support sheet 400; when the flexible screen 300 is in a hidden state, the support rod is folded; when the flexible screen 300 is unfolded, the support rod is unfolded.

[0114] For example, the support rod installed at the bottom of the first shell 110: when the flexible screen 300 is in a hidden state, the end of the support rod connected to the support sheet 400 is located at the top of the preset track, and the support rod is folded and hidden between the first shell 110 and the second shell 210. When the flexible screen 300 is in a hidden state, one end of the support rod rotates relative to the first shell 110, and the other end moves downward along the preset track, thereby unfolding the support rod.

[0115] The preset track is the track of the support rod moving on the support sheet 400, which can be a track groove provided on the support sheet 400, and the support rod is embedded in the track groove; or the preset track is a magnetic area provided on the support sheet 400, and the magnetic area attracts the support rod and the support sheet 400 through magnetic force. The preset track can be linear or curved.

[0116] In other optional embodiments, the edge of the second shell 210 opposite to the body part 100 has a baffle 211;

[0117] The side of the first shell 110 opposite to the second shell 210 has a clamping groove 1121;

[0118] The baffle 211 is located in the clamping groove 1121, and the second screen is in a hidden state.

[0119] For example, the connecting support mechanism 500 includes one or more support rods, one end of the support rod is rotatably connected to the first shell 110, and the other end is installed on the support sheet 400 and can move along a preset track relative to the support sheet 400; when the flexible screen 300 is in a hidden state, the support rod is folded; when the flexible screen 300 is unfolded, the support rod is unfolded. Figures Five to Eight , and Figure ElevenAs shown, the baffle 211 is protruding towards the first housing 110, and the baffle 211 has a channel groove 2111 with an opening facing the first housing 110, and the reel 230 is arranged in the channel groove 2111. One end of the second connecting rod 520 can be mounted in the channel groove 2111. The clamping groove 1121 on the first housing 110 has an opening facing the baffle 211, and one end of the first connecting rod 510 can be mounted in the clamping groove 1121. When the flexible screen 300 is in the hidden state, the baffle 211 is embedded in the clamping groove 1121, which can better protect the flexible screen 300 hidden in the second housing, and on the other hand, it makes the integrity of the first housing 110 and the second housing 210 better, and when the flexible screen 300 is hidden, it is more similar to ordinary hard screen devices, which meets the needs and past experience of users using hard screens and improves the user experience.

[0120] Further, as shown in the drawings, Figure Ten The second housing 210 includes a shell 212 and a bracket 213, and the bracket 213 is partially located in the shell 212 and partially located outside the shell 212 and protrudes towards the first housing 110 to form the baffle 211. The bracket 213 located in the shell 212 has a containing cavity 2131 for containing the reel 230 and the bearing 220, and the flexible screen 300 moves outward from the containing cavity 2131 through the channel groove 2111. The bearing 220 is fixed on the bracket 213 by the limiting action of the containing cavity 2131.

[0121] In other optional embodiments, the outer wall of the reel 230 is provided with a shaft groove;

[0122] The reel part 200 further includes a clamping spring embedded in the shaft groove and located outside the bearing 220 and abutting against the bearing 220 to limit the axial movement of the bearing 220.

[0123] Non-limitingly, the clamping spring is annular or C-shaped, and the clamping spring is partially embedded in the shaft groove and mounted, and the bearing 220 is coaxially assembled with the reel 230, and the clamping spring is limited by abutting against the end face of the bearing 220, which suppresses the axial movement of the bearing 220 along the reel 230 and reduces the relative movement of the bearing 220 relative to the reel 230.
