[0033] In order to more clearly understand the above-mentioned purposes, features and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The specific embodiments described herein are merely intended to explain the present application, rather than limit the present application. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present application are within the scope of protection of the present application.

[0034] The present embodiment provides a mobile terminal, which aims to solve the problem that the screen of the mobile terminal in the prior art is not large enough to meet the user experience requirements. The core idea of the present embodiment is to roll up the flexible display screen by using a rolling device, and then unroll the flexible display screen when in use, so as to increase the use area of the display screen.

[0035] In combination Figures 1-3 , the mobile terminal provided by the embodiment includes a shell 3, a battery 1, a display unit, and a control unit 2; the battery 1 and the control unit 2 are both arranged in the shell 3, the display unit and the control unit 2 are both electrically connected with the battery 1, and the control unit 2 is electrically connected with the display unit; the display unit includes a flexible display screen 10, both ends of the flexible display screen 10 are connected on two rotating components 20 respectively, and the flexible display screen 10 can be wound on the rotating components 20, the two rotating components 20 are arranged on two telescopic assemblies 30 respectively, and the two telescopic assemblies 30 are both connected on the shell 3; the flexible display screen 10 has a winding state and an unfolding state, in the winding state, the two telescopic assemblies 30 are contracted, and at least part of the flexible display screen 10 is wound on the two rotating components 20; in the unfolding state, the two telescopic assemblies 30 are elongated, and the flexible display screen 10 is completely unfolded.

[0036] The mobile terminal can be a mobile phone, a tablet computer, an MP4, or other devices with a display screen. Through the above scheme, the screen display area of the mobile terminal is increased, and the increased proportion is relatively large, which can be 2-3 times of the original area. For watching videos, reading news and novels, video calls, etc., it is more panoramic, and a full-screen exceeding 100% is realized. In addition, it can be folded and unfolded. When it is not unfolded, it can be shrunk for normal mobile phone use, which does not affect the convenience of carrying. When the flexible display screen 10 is shrunk, it is as shown in Figure 1 , 3 ; when it is shrunk and becomes a normal mobile phone, it is also a 3D curved surface display, that is, the two ends of the screen are arc surfaces.

[0037] In a specific embodiment, each telescopic assembly 30 includes two second telescopic rods 4, one end of each second telescopic rod 4 is hinged with the shell 3, and the other end is connected with the end of the corresponding rotating component 20. In the winding state, the flexible display screen 10 is partially wound on the rotating component 20 (as shown in Figure 1 ; in the unfolding state, the flexible display screen 10 is completely unfolded (as shown in Figure 2 ). The switching between the two states can be realized by manually winding, for example, from the winding state to the unfolding state, the user can pull the rotating components 20 at both ends, and the rotating components 20 are unfolded outward while rotating; from the unfolding state to the winding state, the user can wind the two rotating components 20 respectively, so that part of the flexible display screen 10 is wound up, and the winding state is restored. Figure 1

[0038] ​Further, in order to ensure the stability of the mobile terminal in the rolled-up state or the unfolded state, in the embodiment, the telescopic assembly 30 further comprises a locking member connected with the second telescopic rod 4, which is used to lock the length of the second telescopic rod 4 in the rolled-up state and the unfolded state. That is, when the positions of the rolled-up state and the unfolded state are adjusted, the second telescopic rod 4 is fixed by the locking member, so that the second telescopic rod 4 cannot freely extend or retract, thereby ensuring the stability of the flexible display 10 in the current position.

[0039] In the embodiment, the housing 3 is formed with a circular arc groove 5 at both ends, and the rolled-up part of the flexible display 10 is located in the circular arc groove 5 in the rolled-up state. The circular arc groove 5 can provide a placement space for the flexible display 10 in the rolled-up state, thereby avoiding damage from the outside.

[0040] In the embodiment, the width of the part of the flexible display 10 that can be rolled up accounts for at least 1 / 2 of the entire width of the flexible display 10. Thus, the screen of the mobile terminal can be expanded by more than twice the original size.

[0041] Referring to Figures 4-6 , in order to improve the convenience of use of the mobile terminal, in another embodiment, each telescopic assembly 30 comprises two telescopic members 31 electrically connected with the control unit 2, the two telescopic members 31 are respectively connected to both ends of the corresponding rotating member 20, and the two telescopic members 31 can drive the rotating member 20 to rotate in the process of extension or retraction. The control unit 2 can control the telescopic members 31 to extend or retract, and at the same time control the rotating member 20 to rotate, so that the user does not need to manually control the unfolding and retraction of the flexible display 10.

[0042] Specifically, referring to Figure 5 and Figure 6 , each telescopic member 31 comprises a driving member 311, a screw rod 312, a first telescopic rod 313, and a push rod 314. The control unit 2 is electrically connected with the driving member 311, and the control unit 2 can control the driving member 311 to start. The driving member 311 is connected with the screw rod 312 to drive the screw rod 312 to rotate. The screw rod 312 has external threads on the outside and a central hole formed in the inside. The push rod 314 has a hollow structure and is formed with internal threads matched with the screw rod 312. The push rod 314 can move along the axial direction of the screw rod 312 in the process of rotation of the screw rod 312. One end of the first telescopic rod 313 is arranged in the central hole and connected with the screw rod 312 or the driving member 311, so that the first telescopic rod 313 can rotate synchronously with the screw rod 312. The other end of the first telescopic rod 313 is provided with a gear turntable 315, which rotates synchronously with the first telescopic rod 313. The end of the rotating member 20 is provided with a rack 23, and the gear turntable 315 is matched with the rack 23, so that the gear turntable 315 can drive the rotating member 20 to rotate.

[0043] Referring to Figure 5 In the winding state, the first telescopic rod 313 is in the contracted state. When it is needed to unfold the flexible display screen 10, the control unit 2 controls the driving component 311 to start, and further drives the screw rod 312 to rotate. Since the screw rod 312 and the push rod 314 are in cooperation through the thread, the push rod 314 moves outward when the screw rod 312 rotates, thereby driving the first telescopic rod 313 to elongate. Meanwhile, the gear turntable 315 rotates with the screw rod 312, and drives the rotating component 20 to rotate through the rack 23, thereby unfolding the part of the flexible display screen 10 wound on the rotating component 20. After being unfolded, it is as shown in FIG. 5. This scheme does not need to set the locking component, and the rotating component 20 can always be in the self-locking state under the cooperation of the gear turntable 315 and the rack 23. The elongation and contraction of the first telescopic rod 313 are controlled by the driving component 311, and therefore the use convenience is greatly improved for the user. Figure 6

[0044] Further, the hollow structure of the push rod 314 includes a screwing-in section and a non-screwing-in section, and the barrier 316 is arranged between the screwing-in section and the non-screwing-in section. The inner thread is arranged in the screwing-in section, the first telescopic rod 313 passes through the barrier 316 and only has the circumferential freedom degree under the constraint of the barrier 316, and the gear turntable 315 is located in the non-screwing-in section. The barrier 316 functions to constrain the first telescopic rod 313, avoids the gear turntable 315 from moving relative to the push rod 314, and meanwhile ensures that the first telescopic rod 313 can rotate synchronously with the screw rod 312.

[0045] The non-screwing-in section mainly serves as the placement space of the gear turntable 315. The push rod 314 is provided with a gap in the non-screwing-in section, which is used for making the gear turntable 315 extend from the hollow structure of the push rod 314 and cooperate with the rack 23. For the person skilled in the art, the gear turntable 315 and the rack 23 are mainly arranged to realize the transmission between the first telescopic rod 313 and the rotating component 20. In addition to this transmission mode, the worm and gear mode can also be adopted, for example, the worm is arranged at the end of the first telescopic rod 313, the worm wheel is arranged at the end of the rotating component 20, and the worm and the worm wheel are meshed with each other, thereby realizing the transmission between the first telescopic rod 313 and the rotating component 20.

[0046] In this embodiment, the rotating component 20 includes the rotating shaft 21 and the rotating body 22. The two ends of the rotating shaft 21 are respectively arranged on the corresponding push rod 314, the rotating body 22 is arranged on the rotating shaft 21 and can rotate around the rotating shaft 21, and the rack 23 is arranged on the rotating body 22. The driving component 311 is a stepping motor.

[0047] ​It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
