An electronic device according to an embodiment of the present application is described below with reference to fig. 1 to 13.

As shown in fig. 1 to 4, an embodiment of the present application discloses an electronic device 100, the electronic device 100 has a folded state and an unfolded state, the electronic device 100 includes a support structure 10 and a flexible display 20, the support structure 10 supports the flexible display 20, the support structure 10 includes a first support body 1, a second support body 2, a third support body 3 and a traction assembly 4, the second support body 2 is slidably connected with the first support body 1, the third support body 3 is rotatably connected with the first support body 1 through a rotation shaft 5; the traction assembly 4 comprises a first traction rope 41 and a second traction rope 42, one end of the first traction rope 41 and one end of the second traction rope 42 are connected with the second supporting body 2, and the other end of the first traction rope 41 and the other end of the second traction rope 42 are wound on the peripheral side 2 of the rotating shaft 5 along opposite directions and are connected; when the first support 1 and the third support 3 rotate relatively, the electronic device 100 switches between an unfolded state and a folded state, and the traction assembly 4 drives the second support 2 to slide relative to the first support 1 so as to support the flexible display 20.

The electronic device 100 provided by the present application may be a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted device, a mobile internet device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), an internet book or a personal digital assistant (personal digital assistant, PDA), or may be a personal computer (personal computer, PC), a Television (TV), a teller machine or a self-service machine, etc., which is not limited in the embodiments of the present application.

One end of the flexible display 20 may be connected to the first support 1 and the other end may be connected to the third support 3 around the rotation shaft 5. The electronic device 100 provided by the application can adopt an outward folding structure, and when the supporting structure 10 is in a folding state, the front and back sides of the electronic device 100 are two independent display areas. Of course, an invagination scheme may be adopted, at this time, an additional display screen needs to be provided on the second support body 2 or the third support body 3, and in the case that the support structure 10 is in the folded state, the display operation may be performed by using the additionally provided display screen.

In the support structure 10 disclosed in the present application, the third support body 3 can relatively rotate to different positions with respect to the first support body 1, so as to realize switching between the folded state and the unfolded state of the electronic device 100.

Illustratively, the angle between the first support 1 and the third support 3 may be 0 ° in the folded state, and the angle between the first support 1 and the third support 3 may be 180 ° in the unfolded state. The angle between the first support 1 and the third support 3 may gradually increase from 0 ° to 180 °, and the angle between the first support 1 and the third support 3 may also gradually decrease from 180 ° to 0 °.

As shown in fig. 2, when the support structure 10 is in the folded state, the first support body 1 and the second support body 2 overlap the third support body 3 in the second direction Y, so that the volume of the support structure 10 is small; as shown in fig. 1, when the support structure 10 is in the unfolded state, the included angle between the first support body 1 and the third support body 3 increases, so that the volume of the support structure 10 increases. When the support structure 10 is in the folded state, the support structure 10 has a smaller volume, and only the areas on the first support 1 and the second support 2 or only the area on the third support 3 in the flexible display screen are displayed. When the support structure 10 is in the unfolded state, the volume of the support structure 10 is increased, and the areas on the first support body 1, the second support body 2 and the third support body 3 in the flexible display screen are displayed together, so that a larger display area is obtained.

The second support body 2 is in sliding connection with the first support body 1, and the third support body 3 is in rotary connection with the first support body 1 through a rotary shaft 5, so that the third support body 3 can realize rotary and translational movement relative to the second support body 2. When the electronic device 100 is switched between the folded state and the unfolded state, the third support body 3 and the first support body 1 relatively rotate, and the second support body 2 and the first support body 1 relatively slide, so that the support structure 10 can be adapted to flexible display screens in different states.

The traction assembly 4 comprises a first traction rope 41 and a second traction rope 42, the rotating shaft 5 is fixedly connected with the third support body 3, one end of the first traction rope 41 and one end of the second traction rope 42 are respectively connected with the second support body 2, and the first traction rope 41 and the second traction rope 42 are wound on the periphery side of the rotating shaft 5 along different directions, so that one of the first traction rope 41 and the second traction rope 42 can be wound and the other one can be unwound when the rotating shaft 5 rotates. Alternatively, the first traction rope 41 and the second traction rope 42 may be metal ropes, nonmetal ropes, or the like having flexibility, and the present application is not limited thereto. Both ends of the first traction rope 41 and the second traction rope 42 may be fixed to the second supporting body 2 and the rotating shaft 5 by means of riveting, welding, threading, or the like.

Referring to fig. 4 and fig. 5, with the first support 1 as a reference, in the process of switching the support structure 10 from the unfolded state to the folded state, an acting force may be applied to the third support 3, the third support 3 and the rotating shaft 5 rotate together along the first rotation direction Z1 about the central axis of the rotating shaft 5, the included angle between the third support 3 and the second support 2 is gradually reduced, the rotating shaft 5 winds at least part of the first traction rope 41, and the first traction rope 41 applies a traction force to the second support 2 in a direction approaching to the first support 1, so that the second support 21 moves in a direction approaching to the first support 1, which may also be understood as that the first support 1 and the second support 2 approach each other. The direction approaching the first support 1 may be defined as a first translation direction X1 for convenience of description herein. The first rotation direction Z1 here means that the third support body 3 rotates around the center axis of the rotation shaft 5 toward the side of the second support body 2. Since the first traction rope 41 and the second traction rope 42 can be wound around the rotation shaft 5 in opposite directions, respectively, during the switching of the support structure 10 from the unfolded state to the folded state, the rotation shaft 5 winds up at least part of the first traction rope 41, while the rotation shaft 5 unwinds at least part of the second traction rope 42.

Referring to fig. 6 and fig. 7, with the first supporting body 1 as a reference, in the process of switching the electronic device 100 from the folded state to the unfolded state, an acting force can be applied to the third supporting body 3, the third supporting body 3 and the rotating shaft 5 rotate around the central axis of the rotating shaft 5 along the second rotation direction Z2, the angle between the third supporting body 3 and the second supporting body 2 is gradually increased, the rotating shaft 5 winds at least part of the second traction rope 42, and the second traction rope 42 applies a traction force to the second supporting body 2 in a direction away from the first supporting body 1, so that the second supporting body 2 moves in a direction away from the first supporting body 1, which can also be understood as that the first supporting body 1 and the second supporting body 2 are far away. The direction in which it is directed away from the first support 1 may be defined herein as the second translation direction X2 for convenience of description. The second rotation direction Z2 here means that the third support body 3 rotates around the center axis of the rotation shaft 5 toward the side away from the second support body 2. The first rotation direction Z1 and the second rotation direction Z2 are opposite to each other, and the first translation direction X1 and the second translation direction X2 are opposite to each other. For example, the first rotational direction Z1 may be a counterclockwise direction and the second rotational direction Z2 may be a clockwise direction. The first translation direction X1 is a direction in which the second support 2 is retracted to the first support 1, and the second support 2 is retracted to the first support 1, so that an area in which the second support 2 and the first support 1 can support the flexible display 20 is reduced. The second translation direction X2 is a direction in which the second support body 2 protrudes to the first support body 1, so that an area in which the second support body 2 and the first support body 1 can support the flexible display screen 20 increases.

In the scheme disclosed by the application, the first support body 1 and the third support body 3 are rotatably connected, so that the third support body 3 can rotate relative to the first support body 1, the support structure 10 can be folded or unfolded along with the flexible display screen 20, and the first traction rope 41 and the second traction rope 42 are arranged, so that the first traction rope 41 and the second traction rope 42 can drag the second support body 2 to slide relative to the first support body 1 along with the relative rotation of the first support body 1, so that the flexible display screen 20 with different bending radiuses can be supported well by the support structure 10 in a folding state and an unfolding state, and the flexible display screen 20 is prevented or reduced from being pulled or extruded to a certain extent. Compared with the hinge assembly in the related art, the first traction rope 41 and the second traction rope 42 in the application have fewer parts and simple structure, and can reduce the weight of the support structure 10, thereby being beneficial to the development of the light and thin support structure 10. The first traction rope 41 and the second traction rope 42 are adopted to drag the first support body 1 to translate relative to the second support body 2, so that the phenomenon that a rotating structure connected with the hinge assembly rotates unsmoothly or is blocked due to small assembly gaps of the hinge assembly is avoided, and the phenomenon that the hinge assembly and the rotating structure connected with the hinge assembly are dislocated and loose due to large assembly gaps of the hinge assembly is avoided.

Referring to fig. 4 and 8, the first traction rope 41 may be a flexible rope, and the flexible rope may be directly connected to the second support body 2 after being fixed to the rotating shaft 5 and rotating around the rotating shaft 5. With the first supporting body 1 as a reference object, the rotating shaft 5 rotates along the first rotating direction Z1 to wind the first traction rope 41, the length of a part of the first traction rope 41 between the rotating shaft 5 and the second supporting body 2 is shortened, and the first traction rope 41 pulls the second supporting body 2 to be close to the first supporting body 1, namely, the first traction rope 41 pulls the second supporting body 2 to be close to the rotating shaft 5.

Referring to fig. 6 and 7, if the second traction rope 42 and the first traction rope 41 adopt the same layout path, are fixed to the rotating shaft 5, and are directly connected to the second support 2 after rotating around the rotating shaft 5, the second traction rope 42 is wound around the rotating shaft 5 along the second rotation direction Z2, the length of the portion of the second traction rope 42 between the rotating shaft 5 and the second support 2 is shortened, the second traction rope 42 still pulls the second support 2 to approach the first support 1, and it is impossible for the second traction rope 42 to apply a traction force to the second support 2 to drive the second support 2 to translate away from the rotating shaft 5. Therefore, the second traction rope 42 needs to adopt a different layout path from the first traction rope 41, and the second traction rope 42 can apply traction force for driving the second support body 2 to translate away from the rotating shaft 5 to the second support body 2 by laying structural members with reversing function. In some embodiments, the first support body 1 includes a guiding seat 11, and the second traction rope 42 is connected to the second support body 2 after winding an end of the guiding seat 11 facing away from the rotating shaft 5.

The second traction rope 42 is fixed with the rotating shaft 5, extends to the reversing hole 12 along the guide seat 11 after rotating around the rotating shaft 5, passes through the reversing hole 12 and is connected with the second support body 2. In the case where the second traction rope 42 pulls the second supporting body 2, the direction of the pulling force conducted by the portions of the second traction rope 42 located at both sides of the reversing hole 12 is opposite.
