Detailed Description

The embodiment of the application provides a folding electronic device, in particular to an inner folding electronic device. The foldable electronic device may be a mobile phone, a wearable device, a virtual reality device, or a mobile computing device, and other electronic devices with a display screen, which is not limited in this embodiment of the present application. For convenience of description, the foldable electronic device is exemplified as a mobile phone in the present application.

The following describes in detail a foldable electronic device provided in an embodiment of the present application with reference to fig. 1 to 9.

The folding electronic device includes a body and a flexible screen 200 attached to the body. Fig. 1 is a schematic view of a foldable electronic device according to an embodiment of the present disclosure when folded, and fig. 2 is a schematic view of the foldable electronic device according to the embodiment of the present disclosure when unfolded. As shown in fig. 1 and 2, the foldable electronic device includes two states of folding and unfolding, and the body drives the flexible screen 200 to fold when folded so as to reduce the size of the foldable electronic device, thereby facilitating holding and carrying; when the flexible screen is unfolded, the flexible screen 200 is driven by the body to be unfolded so as to increase the display area.

The flexible screen 200 refers to a display screen that can be bent, for example, the flexible screen 200 may be an OLED display screen, an AMOLED display screen, or the like. The internal structure of the flexible screen 200 can refer to the content in the related art, and will not be described in detail herein.

Fig. 3 is a schematic structural diagram of a foldable electronic device according to an embodiment of the present disclosure when a body is unfolded. Fig. 4 is a schematic structural diagram of a body of a foldable electronic device according to an embodiment of the present application when the body is folded. As shown in fig. 3 and 4, the body includes a first body 10 and a second body 20 that are foldably connected, and the first body 10 and the second body 20 serve as a framework of the foldable electronic device for supporting, connecting or accommodating other components of the foldable electronic device. For example, a battery, a processor, a memory, a main board, a communication module, a camera module, etc. may be provided in the first body 10 and the second body 20 as necessary.

Referring to fig. 3, the first body 10 is provided with a first supporting surface 11, the second body 20 is provided with a second supporting surface 21, when the foldable electronic device is unfolded, the first supporting surface 11 and the second supporting surface 21 are located on the same side of the foldable electronic device, and the flexible screen 200 covers the first supporting surface 11 and the second supporting surface 21.

When the user uses the flexible screen, for example, the first body 10 is held by the left hand, and the second body 20 is held by the right hand, so that the first supporting surface 11 and the second supporting surface 21 face the user, that is, the flexible screen 200 faces the user, so that the user can view the image displayed on the flexible screen 200.

Referring to fig. 4, when the folding electronic device is folded, the first supporting surface 11 and the second supporting surface 21 are opposite, that is, the first body 10 and the second body 20 are overlapped.

Illustratively, when the folding electronic device is unfolded, the first body 10 and the second body 20 are located on the same plane, so that the first supporting surface 11 and the second supporting surface 21 are coplanar, thereby forming a rectangular supporting surface, and the flexible screen 200 is also rectangular and covers the supporting surface. When the folding electronic device is folded, the first body 10 and the second body 20 are stacked such that the first supporting surface 11 and the second supporting surface 21 are opposed.

When the foldable electronic device is unfolded, the first supporting surface 11 and the second supporting surface 21 may not be coplanar, but may form an included angle, for example, the first supporting surface 11 and the second supporting surface 21 are V-shaped.

The first body 10 and the second body 20 may be foldably connected by a hinge structure or other flexible structures, and the connection structure for the foldable connection of the first body 10 and the second body 20 is not limited in this application.

In the related art, when the folding electronic device is folded, the first supporting surface 11 and the second supporting surface 21 are opposite to each other, and therefore the flexible screen 200 covered on the first supporting surface 11 and the flexible screen 200 covered on the second supporting surface 21 are also opposite to each other, that is, the flexible screen 200 is bent. Because the folding electronic device is an inner folding electronic device, the bending radius of the flexible screen 200 is small during folding, which causes the flexible screen 200 to generate plastic deformation at the bending position, thereby generating a crease at the bending position.

In view of this, the folding electronic device further includes a driving device connected to the flexible screen 200, and the driving device may drive the flexible screen 200 to move.

Specifically, when the folding electronic device is folded, the first end of the flexible screen 200 is driven by the driving device to bend to the side away from the first supporting surface 11, and the second end of the flexible screen 200 covers the first supporting surface 11. The first end of the flexible screen 200 is an end of the foldable electronic device that covers the first supporting surface 11 when the foldable electronic device is unfolded, and the second end of the flexible screen 200 is an end of the foldable electronic device that covers the second supporting surface 21 when the foldable electronic device is unfolded.

Optionally, an arc surface 12 is disposed at an end of the first body 10 away from the second body 20, and when the foldable electronic device is folded, the first end of the flexible screen 200 is driven by the driving device to bend along the arc surface 12 to a side away from the first supporting surface 11.

Fig. 5 is a schematic view of a foldable electronic device according to an embodiment of the present application when being unfolded, and fig. 6 is a schematic view of the foldable electronic device according to the embodiment of the present application when being folded. As shown in fig. 5 and 6, during the folding electronic device from the unfolded state to the folded state, the first end of the flexible screen 200 moves toward the arc 12 and bends to the side away from the first supporting surface 11 under the support of the arc 12, so that the second end of the flexible screen 200 moves from the second supporting surface 21 to the first supporting surface 11 through the junction 30 between the first body 10 and the second body 20.

Since the second end of the flexible screen 200 covers the first supporting surface 11, that is, the flexible screen 200 is not covered on the second supporting surface 21 and the boundary 30 between the first body 10 and the second body 20, the flexible screen 200 is not bent at the boundary 30 between the first body 10 and the second body 20, but only at the arc surface 12.

In the embodiment of the present application, the radius of the arc surface 12 is larger than the folding radius of the first body 10 and the second body 20. The folding radius of the first body 10 and the second body 20 refers to a radius of the first supporting surface 11 and the second supporting surface 21 when the folding electronic device is folded. Because the radius of the arc surface 12 is greater than the folding radius, the bending radius of the flexible screen 200 in the embodiment of the present application is greater than the bending radius of the flexible screen 200 in the related art, so that the flexible screen 200 is not easily subjected to plastic deformation, and the probability of the flexible screen 200 generating creases is reduced.

The arc surface 12 may be a circular arc surface, or may be another arc surface with smooth transition. When the arc 12 is a smooth transition arc, the radius of the arc 12 may be the radius of curvature of the arc. In summary, the purpose of the curved surface 12 is to bend the flexible screen 200 along the curved surface 12 to have a larger bending radius and less plastic deformation than the related art bending radius at the boundary 30 between the first body 10 and the second body 20.

It will be appreciated that the curved face 12 is convex towards the outside of the first body 10 to support the flexible screen 200 to bend to the side facing away from the first support face 11.

In order to make the flexible screen 200 fit to the first body 10 and the second body 20 during the movement process, the first body 10 and the second body 20 are further provided with a clamping groove extending along the movement direction of the flexible screen 200, and the side edge of the flexible screen 200 is embedded into the clamping groove, so that the side edge of the flexible screen 200 moves in the clamping groove, thereby limiting the position of the flexible screen 200.

Illustratively, as shown in fig. 7, the folding electronic device further includes a frame 70, the frame 70 is disposed at the periphery of the first body 10 and the second body 20, the frame 70 is provided with edges parallel to the first supporting surface 11 and the second supporting surface 21, a slot is formed between the edges and the space between the first supporting surface 11 and the second supporting surface 21, and the side of the flexible screen 200 is embedded in the slot.

It should be noted that, in order to make the first body 10 and the second body 20 more easily folded, no edge may be provided at the boundary 30 of the first body 10 and the second body 20.

In practical applications, when the foldable electronic device is unfolded, the flexible screen 200 covers the first supporting surface 11 and the second supporting surface 21 to form a main display area a. The main display area a has a large display area, and is generally used in scenes with many display contents, such as pictures, videos, and the like, or in multitask processing.

In the scenes with less display contents such as telephones, short messages, instant messaging software and the like, the required display area is smaller. Therefore, in order to reduce power consumption and to enable normal use even in a folded state, a separate display screen needs to be disposed on the other side of the first body 10 opposite to the first supporting surface 11, thereby forming the sub display region B. However, providing a separate display increases the manufacturing cost of the folding electronic device.

In this embodiment, a third supporting surface 13 may be disposed on the other side of the first body 10 opposite to the first supporting surface 11, and when the foldable electronic device is folded, the first end of the flexible screen 200 covers the third supporting surface 13, so that the flexible screen 200 covered on the third supporting surface 13 may serve as the secondary display area B.

Illustratively, the flexible screen 200 displays an image on a portion thereof overlaid on the third supporting surface 13, and does not display an image on the other portion thereof. Alternatively, the flexible screen 200 displays an image in a portion overlapping the third supporting surface 13 and the arc surface 12, and does not display an image in a portion overlapping the first supporting surface 11.

Of course, an opening communicating with the internal cavity of the first body 10 may also be provided between the first supporting surface 11 and the third supporting surface 13, and the first end of the flexible screen 200 is bent along the arc surface 12 and then extends into the internal cavity of the first body 10 through the opening.

The folding electronic device may further include a flexible member connecting the driving means and the flexible screen 200, and the driving means drives the flexible screen 200 to move by winding the flexible member.

The flexible member refers to a connecting member that can be bent along the arc 12, and the flexural modulus of the flexible member may be the same as or similar to the flexural modulus of the flexible screen 200, so that the flexible member and the flexible screen 200 have approximately the same bending performance.

The flexible member may be in the form of a sheet, a strip, a wire, etc., as long as it can be wound to draw the flexible screen 200 to move. For example, when the flexible member is in the form of a wire, the driving means may include a roller, one end of the wire-shaped flexible member is connected to the flexible screen 200, and the other end of the wire-shaped flexible member is wound on the roller, and the flexible member is wound or unwound on the roller when the roller rotates, thereby drawing the flexible screen 200 to move.

The flexible screen 200 driven by winding the flexible member has a simple structure, and the flexible member can be bent along the arc surface 12, so that the driving device can change the direction of the driving force through the flexible member. In addition, part of the flexible piece is wound on the driving device, so that the space is saved.

The flexible member and the flexible screen 200 may be connected by bonding or the like, or may be an integrated structure. When the flexible part and the flexible screen 200 are of an integrated structure, the flexible part and the flexible screen 200 are connected more firmly, connecting seams between the flexible part and the flexible screen 200 are eliminated, and the visual effect is better.

Illustratively, the flexible screen 200 includes a first flexible substrate layer, the flexible member includes a second flexible substrate layer, and the first flexible substrate layer and the second flexible substrate layer are disposed on the same layer and are of an integral structure. The flexible substrate layer may be a polyimide film, or may be made of other flexible materials.

When the flexible screen 200 and the flexible member are manufactured, a flexible substrate layer may be manufactured, a layer structure of the flexible display screen such as a driving circuit layer and a light emitting layer may be manufactured at a position corresponding to the flexible screen 200 on the flexible substrate layer, and the driving circuit layer and the light emitting layer may not be manufactured at a position corresponding to the flexible member on the flexible substrate layer.

When the flexible member lacks a layer structure of a driving circuit layer, a light emitting layer, and the like, compared to the flexible panel 200, the thickness of the flexible member may be thinner than that of the flexible panel 200. Of course, other layer structures may be provided on the flexible member at positions corresponding to the layer structures such as the driving circuit layer and the light emitting layer, so that the flexible member and the flexible panel 200 have the same thickness and the same bending modulus.

Fig. 8 is a schematic view of the first winding shaft in the embodiment of the present application when winding, and fig. 9 is a schematic view of the first winding shaft in the embodiment of the present application when unwinding. As shown in fig. 8 and 9, the driving means may include a rotatable first reel 51, the flexible member including a first flexible member 41, one end of the first flexible member 41 being connected to the first end of the flexible screen 200 at a first connection C, and the other end of the first flexible member 41 being wound on the first reel 51. The movement of driving the flexible screen 200 by winding the first flexible member 41 around the first winding shaft 51 is simple, and the first flexible member 41 can be bent along the arc 12, so that the first winding shaft 51 can change the direction of the driving force by the first flexible member 41. In addition, a part of the first flexible member 41 is wound on the first reel 51, saving space.

Illustratively, as shown in fig. 5 and 6, the first reel 51 is located in the first body 10, the junction 30 of the first body 10 and the second body 20 is parallel to the first reel 51, the first flexible member 41 is in a sheet shape, one end of the first flexible member 41 is wound on the first reel 51, and the other end of the first flexible member 41 is connected to the flexible screen 200. The first body 10 is provided with a first reel bin 61 corresponding to the position of the first reel 51, and the size of the first reel bin 61 is larger than that of the first reel 51, so that the first flexible member 41 wound on the first reel 51 can be accommodated in the first reel bin 61.

In addition, in an embodiment where the first body 10 is provided with the third supporting surface 13, in order to cover the first end of the flexible screen 200 on the third supporting surface 13, the first reel 51 may be provided adjacent to the boundary 30 of the first body 10 and the second body 20.

Of course, the first winding shaft 51 may be disposed at other positions, for example, away from the boundary 30 between the first body 10 and the second body 20, and in this case, a turning structure needs to be disposed near the boundary 30 between the first body 10 and the second body 20, so that the first flexible element 41 is bent through the turning structure.

When the folding electronic device is folded, the flexible screen 200 is driven by the first reel 51 to bend along the arc 12, and when the folding electronic device is unfolded, the flexible screen 200 needs to be driven by the driving device to move towards the second body 20, so that the flexible screen 200 covers the first supporting surface 11 and the second supporting surface 21.

Therefore, the driving device may further include a second reel 52 rotatable, and the flexible member further includes a second flexible member 42, one end of the second flexible member 42 is connected to the second end of the flexible screen 200 at a second connection D, and the other end of the second flexible member 42 is wound on the second reel 52.

Illustratively, the second reel 52 is disposed at an end of the second body 20 away from the first body 10, so that the second reel 52 can pull the flexible screen 200 to cover the second supporting surface 21.

The second reel 52 and the second flexible member 42 may have the same structure as the first reel 51 and the first flexible member 41, or may have different structures. When the same, reference may be made to the first reel 51 and the first flexible member 41 with respect to the structure and connection relationship of the second reel 52 and the second flexible member 42, which will not be described in detail herein.

The driving device further comprises a driving motor 53, and the driving motor 53 may comprise two driving motors, one driving motor is in driving connection with the first winding shaft 51, and the other driving motor is in driving connection with the second winding shaft 52, and is used for driving the first winding shaft 51 and the second winding shaft 52 to rotate.

For example, when the folding electronic device is folded, the driving motor 53 drives the first reel 51 to wind the first flexible member 41, and simultaneously the driving motor 53 drives the second reel 52 to unwind the second flexible member 42, so that the first end of the flexible screen 200 is bent along the arc 12. When the folding electronic device is unfolded, the driving motor 53 drives the second reel 52 to wind the second flexible member 42, and simultaneously the driving motor 53 drives the first reel 51 to unwind the first flexible member 41, so that the flexible screen 200 is covered on the first supporting surface 11 and the second supporting surface 21.

The driving motor 53 may also include one, the driving motor 53 is in transmission connection with one of the first reel 51 and the second reel 52, and the other of the first reel 51 and the second reel 52 is driven by a coil spring.

For example, the driving motor 53 is drivingly connected to the first spool 51, and the coil spring is connected to the second spool 52. When the folding electronic device is folded, the driving motor 53 drives the first reel 51 to wind the first flexible member 41, pulls the second flexible member 42 to unwind from the second reel 52, and the second reel 52 drives the coil spring to deform to generate an elastic force during rotation. When the folding electronic device is unfolded, the driving motor 53 drives the first reel 51 to unwind the first flexible member 41, and the second reel 52 rotates under the elastic force of the coil spring so that the second flexible member 42 is wound on the second reel 52.

Of course, when the driving motor 53 includes one driving motor 53, the driving motor 53 may also be connected to the first winding shaft 51 and the second winding shaft 52 in a driving manner, and the first winding shaft 51 and the second winding shaft 52 may rotate in opposite directions through a driving member such as a gear.

The output shaft of the driving motor 53 may be perpendicular to the first and second reels 51 and 52. When the output shaft of the driving motor 53 is perpendicular to the first winding shaft 51 and the second winding shaft 52, the size of the folding electronic device along the direction of the first winding shaft 51 can be reduced, thereby improving the screen occupation ratio of the folding electronic device.

Illustratively, as shown, a drive motor 53 is drivingly connected to the first and second spools 51, 52 via a bevel gear set 54. Of course, the driving motor 53 may also be in transmission connection through a worm gear.
