Referring to fig. 1, the present embodiment provides a mobile terminal, which includes a first display screen 10, a first turning mechanism 20 and a second turning mechanism 30 respectively disposed on two opposite sides of the first display screen 10, wherein the first turning mechanism 20 is further connected to a side of a second display screen 40, the second turning mechanism 30 is further connected to a side of a third display screen 50, the second display screen 40 can be rotated to overlap the first display screen 10 through the first turning mechanism 20, and the third display screen 50 can be rotated to overlap the first display screen 10 through the second turning mechanism 30. The mobile terminal can be folded or unfolded respectively in a double-shaft mode, has multiple folding and unfolding using states, and improves using diversity and environmental adaptability.
The first turning mechanism 20 is connected between the first display screen 10 and the second display screen 40, and is configured to allow the second display screen 40 to rotate relative to the first display screen 10 through the first turning mechanism 20, so that the second display screen 40 can be overlapped with the first display screen 10, and the mobile terminal of the embodiment is in a folded state of the second display screen 40, please refer to fig. 2; or, the second display screen 40 may be located on the same horizontal plane as the first display screen 10, so that the mobile terminal of this embodiment is located in a state where the second display screen 40 is unfolded relative to the first display screen 10, please refer to fig. 3 in combination, where fig. 3 shows that the mobile terminal is located in a completely unfolded state, and at this time, the second display screen 40 is located in an unfolded state relative to the first display screen 10.
Similarly, the second turning mechanism 30 is connected between the first display screen 10 and the third display screen 50, and is configured to allow the third display screen 50 to rotate relative to the first display screen 10 through the second turning mechanism 30, so that the third display screen 50 can be overlapped with the first display screen 10, and the mobile terminal of the embodiment is in a folded state of the third display screen 50; or, the third display screen 50 may be located on the same horizontal plane as the first display screen 10, so that the mobile terminal of the embodiment is located in an unfolded state of the third display screen 50 relative to the first display screen 10.
Also, the first folding mechanism 20 is connected between the side of the first display screen 10 and the side of the second display screen 40, and the second folding mechanism 30 is connected between the side of the first display screen 10 and the side of the third display screen 50. Alternatively, in the present embodiment, the rotation direction of the first turning mechanism 20 and the rotation direction of the second turning mechanism 30 may be parallel to each other, i.e., as shown in fig. 3, so that the first display screen 10, the second display screen 40 and the third display screen 50 may be collinear and suitable for information viewing of longer screens. In other embodiments, the rotation direction of the first turning mechanism 20 and the rotation direction of the second turning mechanism 30 may be perpendicular to each other (i.e. the first turning mechanism 20 and the second turning mechanism 30 are respectively disposed at two adjacent sides of the first display screen 10), so that when the three screens are in the fully unfolded state, a wider screen display can be formed, which is suitable for viewing information with a wider screen.
In addition, the first display 10, the second display 40, and the third display 50 may be defined by a single display through human division, or may be three independent displays. In addition, the first display screen 10, the second display screen 40, and the third display screen 50 may be single-screen independent displays, at this time, the three display screens may respectively display different pictures, and multiple screens operate respectively, or may display the same picture for different users to share display information; the display mode of the first display screen 10, the second display screen 40, and the third display screen 50 is not limited in this embodiment for different application scenarios, and those skilled in the art can select a suitable display mode according to a specific use scenario of the mobile terminal and a user requirement.
It should be understood that the first display screen 10, the second display screen 40, and the third display screen 50 of the mobile terminal provided in the present application may be single-sided display (i.e., only one display surface, and the surface opposite to the display surface is a non-display surface), or double-sided display (i.e., both opposite surfaces of the display screen are display surfaces), and are not limited herein. The first display screen 10, the second display screen 40, and the third display screen 50 are all single-sided displays as an example.
According to the above structure, the mobile terminal provided in this embodiment can realize that the second display screen 40 or the third display screen 50 is folded with respect to the first display screen 10, so that the three display screens are in a half-folded state; the three display screens can be completely unfolded to be displayed in a combined mode in the same plane, and therefore the three display screens are in a completely unfolded state; it is also possible to achieve that the second display screen 40 and the third display screen 50 are folded with respect to the first display screen 10, respectively, so that the three display screens are in a fully folded state.
When the mobile terminal is in a semi-folded state: referring to fig. 2, the mobile terminal has three display surfaces. When the user is at a first viewing angle (please refer to fig. 4, the first viewing angle refers to when the second display screen 40 faces the user, the same is true below), the user can view the display information of the mobile terminal through the second display screen 40; when the user is at the second viewing angle (please refer to fig. 5, the second viewing angle is when the second display screen 40 faces away from the user, the same is true below), the user can view the display information of the mobile terminal through the first display screen 10 and the third display screen 50. It should be understood that the first viewing angle and the second viewing angle are only two examples of the embodiment, and in practical applications, when one mobile terminal has multiple users, different users may also view display information of display screens at different viewing angles respectively. For example, when there are two users, one of the two users may be at a first viewing angle and the other may be at a second viewing angle. In this case, the display information of the display screens viewed by the two users may be the same information or different information at the viewing angles of the two users.
When the mobile terminal is in a fully unfolded state: referring to fig. 3, at this time, the mobile terminal still has three display surfaces. When the user is at the first viewing angle, please refer to fig. 6, at this time, the display surfaces of the first display screen 10, the second display screen 40 and the third display screen 50 all face the user, and the user can obtain the display information of the three display screens when using; when the user is at the second viewing angle, please refer to fig. 7, at this time, if the first display screen 10, the second display screen 40, and the third display screen 50 are double-sided display screens, the user can still obtain the display information, and if not, there is no display information.
When the mobile terminal is in a fully folded state: referring to fig. 1, the mobile terminal has only two display surfaces. If the second display screen 40 is located between the first display screen 10 and the third display screen 50 (as shown in fig. 1), at this time, both the first display screen 10 and the third display screen 50 can display corresponding display information, and the second display screen 40 cannot display the display information because it is folded; if the third display screen 50 is located between the first display screen 10 and the second display screen 40 (as shown in fig. 1), at this time, both the first display screen 10 and the second display screen 40 can display corresponding display information, and the third display screen 50 cannot be displayed because it is folded. Specifically, a person skilled in the art can select an appropriate folding manner according to actual needs, thereby determining that a certain display screen is hidden.
In summary, the mobile terminal provided in this embodiment includes a first display screen 10, a first turning mechanism 20 and a second turning mechanism 30 respectively disposed on two opposite sides of the first display screen 10, the first turning mechanism 20 is further connected to a side of a second display screen 40, the second turning mechanism 30 is further connected to a side of a third display screen 50, the second display screen 40 can be rotated to overlap with the first display screen 10 by the first turning mechanism 20, and the third display screen 50 can be rotated to overlap with the first display screen 10 by the second turning mechanism 30. In this way, in the practical application process, the user can select to rotate the second display screen 40 relative to the first display screen 10 through the first turning mechanism 20 according to the requirements of the use scene, so as to unfold or fold the second display screen 40 relative to the first display screen 10; alternatively, the third display screen 50 may be rotated relative to the first display screen 10 by the second turning mechanism 30, so that the third display screen 50 is unfolded or folded relative to the first display screen 10. Thus, various display states such as half-folding, full-folding or full-unfolding of the first display screen 10, the second display screen 40 and the third display screen 50 can be realized, so that the mobile terminal provided by the embodiment has various folding and unfolding use states, and the use diversity and the environmental adaptability of the terminal are improved.
Referring to fig. 8, alternatively, the first turning mechanism 20 includes a rotating shaft 21 and a shape memory alloy portion 22 disposed at an end of the rotating shaft 21, and the second turning mechanism 30 also includes a rotating shaft 21 and a shape memory alloy portion 22 disposed at two ends of the rotating shaft 21. When the shape memory alloy part 22 of the first turning mechanism 20 is in a memory state, a preset acute angle is formed between the non-display surfaces (the non-display surface refers to the surface opposite to the display surface) of the first display screen 10 and the second display screen 40; when the shape memory alloy portion 22 of the second turning mechanism 30 is in the memory state, a predetermined acute angle is formed between the third display screen 50 and the non-display surface of the first display screen 10.
The first turning mechanism 20 and the second turning mechanism 30 each include a rotating shaft 21 and a shape memory alloy portion 22. The rotating shaft 21 of the first turning mechanism 20 is located between the first display screen 10 and the second display screen 40, and the shape memory alloy portion 22 of the first turning mechanism 20 is disposed at an end of the rotating shaft 21 of the first turning mechanism 20, so that when the rotating shaft 21 of the first turning mechanism 20 drives the second display screen 40 to rotate relative to the first display screen 10, the shape memory alloy portion 22 of the first turning mechanism 20 can play an auxiliary role, and the second display screen 40 can be rotated to the memory state of the shape memory alloy portion 22 of the first turning mechanism 20 as soon as possible under the memory state effect of the shape memory alloy portion 22 of the first turning mechanism 20. The working principle of the rotating shaft 21 and the shape memory alloy portion 22 of the second turning mechanism 30 can be obtained in the same way, and will not be described herein.
In addition, the shape memory alloy part 22 of the first turning mechanism 20 and the shape memory alloy part 22 of the second turning mechanism 30 can be set by those skilled in the art, wherein the shape memory alloy part 22 of the first turning mechanism 20 and the shape memory alloy part 22 of the second turning mechanism 30 may be the same or different. Referring to fig. 9, fig. 9 shows that the shape memory alloy portion 22 of the present embodiment is in a memory state when the acute angle is preset, and in this case, the state is a stable state of the mobile terminal, and the second display 40 and the third display 50 can be kept relatively stable in this state. It should be understood that the preset value of the preset acute angle can be determined by one skilled in the art according to the needs, and the application is not limited thereto, for example, the preset acute angle can be 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, and the like.
When the shape memory alloy portions 22 of the first and second turning mechanisms 20 and 30 are in the memory shapes, the mobile terminal is in a relatively stable state, and at this time, the user can select the state shown in fig. 9 to view the display information of each display screen, or the state shown in fig. 10 to vertically place the mobile terminal, so as to conveniently view the display information of the three display screens.
The shape memory alloy portion 22 may be formed of a memory alloy, for example, a single piece of memory alloy connected to the end of the rotation shaft 21, or a single piece of memory alloy connected to the end of the rotation shaft 21.
Further, referring to fig. 8, the shape memory alloy portion 22 may be in a bar shape, in which case, two ends of the bar shape memory alloy portion 22 are respectively attached to the non-display surface of the first display screen 10 and the non-display surface of the second display screen 40 and respectively extend outward, and the shape memory alloy portions 22 disposed at two ends of the rotating shaft 21 are parallel to each other. Thus, the shape memory alloy part 22 can be made of a small amount of material, and the second display screen 40 can be easily rotated to the memory state of the first folding mechanism 20. Similarly, two ends of the bar-shaped shape memory alloy portion 22 may be respectively attached to the non-display surface of the first display screen 10 and the non-display surface of the third display screen 50 and respectively extend outward, and the shape memory alloy portions 22 disposed at two ends of the rotating shaft 21 are parallel to each other.
The shape memory alloy part 22 is attached to the end of the rotating shaft 21, so that the second display screen 40 can rotate relative to the first display screen 10 and the third display screen 50 can rotate relative to the first display screen 10. On the basis, in the embodiment, the two ends of the shape memory alloy portion 22 are further extended outward, so that the two opposite ends of the shape memory alloy portion 22 of the first turning mechanism 20 extend onto the first display screen 10 and the second display screen 40, and the two opposite ends of the shape memory alloy portion 22 of the second turning mechanism 30 extend onto the first display screen 10 and the third display screen 50, so that the stability of the memory state can be enhanced, and the stable state of each display screen can be maintained to a certain extent.

In other embodiments, other forms of memory state reinforcement may be implemented, for example, other locking structures may be provided, so that the second display screen 40 and the third display screen 50 are relatively fixed by way of locking, so that the first display screen 10, the second display screen 40 and the third display screen 50 form a stable triangular structure.
Further, in order to enable the mobile terminal to rotate to the memory state more stably, optionally, both ends of the rotating shaft 21 are provided with shape memory alloy portions 22, and both ends of the shape memory alloy portion 22 of the first turning and folding mechanism 20 are fixedly connected with the first display screen 10 and the second display screen 40, respectively; the shape memory alloy part 22 of the second hinge mechanism 30 has two ends respectively fixedly connected to the first display screen 10 and the third display screen 50.

or, a limiting part 222 is arranged on the periphery of the rotating shaft 21, the display surface of the first display screen 10 and the display surface of the second display screen 40 rotate to the same plane, and the limiting part 222 is abutted with the non-display surface of the second display screen 40 or the non-display surface of the first display screen 10; the display surface of the first display screen 10 and the display surface of the third display screen 50 are turned to the same plane, and the limiting portion 222 abuts against the non-display surface of the third display screen 50 or the non-display surface of the first display screen 10.
For example, referring to fig. 12, an example in which the limiting portion 222 is used for limiting the rotation of the second display screen relative to the first display screen 10 is illustrated. The limiting portion 222 may be connected to the rotating shaft 21 of the first turning mechanism 20, the stopping portion 80 may be disposed at an end of the second display screen 40, and when the second display screen 40 rotates to be located on the same plane as the first display screen 10, the stopping portion 80 is matched with the limiting portion 222, so that the limiting portion 222 limits the rotation of the stopping portion 80, and the second display screen 40 stops rotating and is kept on the same horizontal plane as the first display screen for displaying. Similarly, when the first display panel 10 and the third display panel 50 also need to be rotated for limiting, the limiting portion 222 may be connected to the rotating shaft 21 of the second hinge mechanism 30, and the stopper portion 80 may be provided at the end of the third display panel 50.
It should be understood that the above-mentioned arrangement of the position-limiting portion 222 and the matching manner thereof are only examples, and of course, in other embodiments, the stopping portion 80 may also be arranged on the back plate of the second display screen 40 (and/or the third display screen 50), and the position-limiting portion 222 limits the rotation of the second display screen 40 (and/or the third display screen 50) by limiting the rotation of the back plate of the second display screen 40 (and/or the third display screen 50).
In addition, in this embodiment, the mobile terminal further includes a buffer pad 90, and the buffer pad 90 is respectively disposed between the rotating shaft 21 of the first turning mechanism 20 and the end of the second display screen 40, and between the rotating shaft 21 of the second turning mechanism 30 and the end of the third display screen 50, for playing a buffering role, as shown in fig. 12.
In addition, in order to make the mobile terminal provided in this embodiment be in a relatively stable state when in the fully folded state, optionally, in this embodiment, the mobile terminal further has a locking mechanism, wherein a first matching portion of the locking mechanism may be disposed on the second display screen 40, a second matching portion of the locking mechanism may be disposed on the third display screen 50, and the first matching portion and the second matching portion may be fastened, so that, when in the fully folded state, the second display screen 40 and the third display screen 50 may be relatively fixed.
For example, referring to fig. 13 to 15, the first engaging portion and the second engaging portion may be in magnet attraction engagement. For example, referring to fig. 13 to 15, the first engaging portion may be a fixed magnet 95 disposed on the second display screen, and the second engaging portion may be a moving magnet disposed on the third display screen 50. The movable magnet is driven to move so as to be matched with the fixed magnet 95 for adsorption or to be away from the fixed magnet 95 for desorption, so that the mobile terminal is locked when being in a fully folded state or unlocked when being unfolded.
In order to facilitate the movement of the moving magnet, in this embodiment, a sliding groove may be further disposed on the third display screen 50, and a sliding button 93 is slidably mounted in the sliding groove, and the sliding button 93 may be connected to the moving magnet so as to drive the moving magnet to move. Correspondingly, the third display screen 50 is further provided with a channel for the movement of the moving magnet, so that the moving magnet can have two working positions (for example, a first position a and a second position B), when the moving magnet moves to the second position B, the moving magnet and the fixed magnet 95 attract each other, and the whole machine is in a completely folded and locked state; when the moving magnet moves to the first position a, it is deviated from the fixed magnet 95, the attraction force disappears, and the whole machine can be unfolded.
In addition, it should be noted that, when the mobile terminal is in a half-folded state, for example, when the second display 40 is folded on the first display 10, or when the third display 50 is folded on the first display 10, similarly, the latch mechanism as described above may also be provided to keep the half-folded state relatively stable.
In other embodiments, the first engaging portion may be disposed on the third display 50, and the second engaging portion may be disposed on the first folding mechanism 20, so that the second display 40 and the third display 50 may be relatively fixed when the foldable device is in the fully folded state. Wherein, the arrangement positions of the first matching part and the second matching part can be interchanged.
In this embodiment, a person skilled in the art can select the first display screen 10, the second display screen 40 and the third display screen 50 to be flexible display screens as required.
It should be understood that, the above description is given by taking the mobile terminal as an example, in other embodiments, on the basis of the first display screen 10, the second display screen 40 and the third display screen 50, the mobile terminal provided in this embodiment may further be provided with a fourth display screen, a fifth display screen and the like, and the specific number of the display screens is not limited in this application.
For example, when the mobile terminal provided in this embodiment further has a fourth display screen, optionally, a side of the third display screen 50 away from the second turning mechanism 30 is further rotatably connected with the fourth display screen through the third turning mechanism, and the fourth display screen can be rotated to overlap with the non-display surface of the third display screen 50 through the third turning mechanism. In this case, when the mobile terminal needs to be completely folded, the mobile terminal can be folded from two sides to the middle, the fourth display screen can be folded on the third display screen 50 through the third folding mechanism, the second display screen 40 is folded on the first display screen 10 through the first folding mechanism 20, and finally the third display screen 50 and the fourth display screen which are already folded together and the first display screen 10 and the second display screen 40 which are already folded together are folded.
The foregoing is illustrative of only alternative embodiments of the present application and is not intended to limit the present application, which may be modified or varied by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
