[0037] This application discloses an electronic device for improving the stability of flexible screens.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] The inventors discovered that the rotating shaft currently used to support the screen causes the frequency and amplitude of the screen sliding relative to the two ends (top and bottom) of the rotating shaft to be inconsistent. This makes the screen prone to shaking during the extension and retraction process. In severe cases, the screen may not extend and retract smoothly and may even get stuck. In addition, screen shaking can also generate noise.

[0040] like Figure 1 As shown in the figure, this application provides an electronic device, which may be a laptop computer, a mobile phone, etc.; the electronic device may include a main body, a flexible screen 400, a hinge component 500, and an elastic component 600.

[0041] The flexible screen 400 can be movably connected to the main body. Through the relative movement of the flexible screen 400 and the main body, the electronic device can take on different forms, allowing the flexible screen 400 to easily meet various usage needs. Different forms of electronic devices can result in different unfolded areas of the flexible screen 400 or different positions of the flexible screen 400 relative to the main body. The hinge component 500 supports the flexible screen 400, and the relative movement of the flexible screen 400 and the main body can be driven by the hinge component 500; that is, the movement of the hinge component 500 relative to the main body drives the movement of the flexible screen 400 relative to the main body.

[0042] The rotating shaft component 500 is rotatably connected to the main body; the elastic component 600 is fixedly connected to the rotating shaft component 500. The elastic component 600 includes a target portion that can contact the flexible screen 400. That is, the target portion of the elastic component 600 can be located between the rotating shaft component 500 and the flexible screen 400. As the rotating shaft component 500 moves relative to the main body to provide support for the flexible screen 400, the position of the rotating shaft component 500 supporting the flexible screen 400 moves. The flexible screen 400 can drive the rotating shaft component 500 to rotate through the target portion of the elastic component 600, thereby avoiding relative movement between the flexible screen 400 and the target portion of the elastic component 600 (and between the rotating shaft component 500 and the flexible screen 400).

[0043] That is, while the rotating shaft component 500 supports the flexible screen 400, the flexible screen 400 needs to move synchronously with the rotation of the rotating shaft component 500 to prevent relative sliding displacement between the flexible screen 400, the rotating shaft component 500, and the elastic component 600. Specifically, during the movement of the flexible screen 400 relative to the main body driven by the rotating shaft component 500, the target part can be elastically deformed by the pressure of the flexible screen 400, creating a first target frictional force between the target part and the flexible screen 400, thus ensuring synchronous movement between the elastic component 600 and the flexible screen 400. In other words, the linear velocity of the target part of the elastic component 600 as it rotates with the rotating shaft component 500 is consistent with the movement velocity of the flexible screen 400. The target portion can be elastically deformed by the pressure of the flexible screen 400, so that the target portion of at least the elastic member 600 is located between the flexible screen 400 and the pivot member 500. The flexible screen 400 applies pressure to the pivot member 500 through its tension or tension force, so that the pivot member 500 can support the flexible screen 400. And because the flexible screen 400 applies pressure to the pivot member 500, the target portion can be elastically deformed by the pressure of the flexible screen 400.

[0044] The target part can be elastically deformed by the pressure of the flexible screen 400, so that the pressure between the target part and the flexible screen 400 can include at least the elastic restoring force of the target part. Under the condition that the roughness of the contact surface between the target part and the flexible screen 400 remains unchanged, the elastic restoring force applied by the target part to the flexible screen 400 effectively increases the pressure between the target part and the flexible screen 400. This makes the first target friction force between the target part and the flexible screen 400 greater than the friction force between the flexible screen 400 and the component without elastic restoring force, so as to ensure the synchronous movement of the elastic component 600 and the flexible screen 400. This effectively avoids the relative sliding displacement between the flexible screen 400 and the rotating shaft component 500 and the elastic component 600, thereby improving the stability of the flexible screen 400 during the change of electronic device form and improving or even avoiding the shaking phenomenon of the flexible screen 400.

[0045] Taking a rollable screen device as an example, the flexible screen 400 can be a rollable screen supported by a hinge component 500. The hinge component 500 can drive the flexible screen 400 to move relative to the main body. That is, by changing the position of the hinge component 500 relative to the main body, the hinge component 500 can be supported at different positions on the flexible screen 400, thereby realizing the movement of the flexible screen 400 relative to the main body, changing the orientation and position of at least a part of the flexible screen 400 relative to the main body, and thus adjusting the unfolded area (display area) of the flexible screen 400. The hinge component 500 can move relative to the main body so that it can be supported at different positions on the flexible screen 400. Since the pivot component 500 can support the flexible screen 400 at different positions, the axis of the pivot component 500 can move relative to the flexible screen 400. In order to ensure the stability of the pivot component 500 in supporting the flexible screen 400, the elastic component 600 fixedly connected to the pivot component 500 moves synchronously with the flexible screen 400 to avoid the elastic component 600 (pivot component 500) and the flexible screen 400 from sliding displacement (slippage), thereby avoiding the vibration of the flexible screen 400, making the extension and retraction of the flexible screen 400 smooth, and reducing the noise generated by the vibration of the flexible screen 400 during the extension and retraction process.

[0046] In some embodiments, the elastic member 600 may have a first side and a second side facing away from each other. The first side is fixedly connected to the rotating shaft member 500, and the second side has a target portion for contacting the flexible screen 400. The second side of the elastic member 600 can be entirely composed of target portions to increase the contact area between the elastic member 600 and the flexible screen 400. Alternatively, the second side of the elastic member 600 may have both target portions and non-target portions, arranged in a certain pattern (e.g., alternating along a straight line or distributed in a matrix).

[0047] The elastic component 600 can be sleeved onto the rotating shaft component 500. The inner wall of the elastic component 600 is the first surface, and the outer wall of the elastic component 600 is the second surface. That is, the elastic component 600 can be a sleeve structure, with its inner wall fixedly connected to the rotating shaft component 500 and its outer wall used to contact the flexible screen 400. Alternatively, the elastic component 600 can be a sheet-like structure or a block-like structure, and the elastic component 600 can be located between the rotating shaft component 500 and the flexible screen 400.

[0048] To facilitate the fixed connection between the first surface of the elastic member 600 and the rotating shaft member 500, the inner diameter of the elastic member 600 can be smaller than the diameter of the rotating shaft member 500. That is, in the state where the elastic member 600 has not undergone elastic deformation, its inner diameter is smaller than the diameter of the rotating shaft member 500, making it impossible for the elastic member 600 to be fitted onto the rotating shaft member 500 without elastic deformation. Only by using external force to cause elastic deformation of the elastic member 600 to expand its inner diameter can it be fitted onto the rotating shaft member 500. Therefore, when the elastic member 600 is fitted onto the rotating shaft member 500, it maintains elastic deformation under the pressure of the rotating shaft member 500 on its first surface, creating a second target frictional force between the elastic member 600 and the rotating shaft member 500, thus achieving a fixed connection between the elastic member 600 and the rotating shaft member 500. That is, since the inner diameter of the elastic member 600 is smaller than the diameter of the rotating shaft member 500, when the elastic member 600 is fitted onto the rotating shaft member 500, the rotating shaft member 500 applies pressure to the first surface of the elastic member 600, causing the elastic member 600 to elastically deform. This increases the inner diameter of the elastic member 600 to match the diameter of the rotating shaft member 500. Compared to an elastic member that does not undergo the aforementioned elastic deformation and has an inner diameter greater than or equal to the diameter of the rotating shaft member 500, the second target frictional force between the elastic member 600 and the rotating shaft member 500 in this embodiment is larger, thereby facilitating the fixed connection between the first surface of the elastic member 600 and the rotating shaft member 500.

[0049] Of course, the inner diameter of the elastic component 600 can also be greater than or equal to the diameter of the rotating shaft component 500. This can be achieved by using adhesive or adding connecting parts such as rivets to fix the first surface of the elastic component 600 to the rotating shaft component 500. No specific restrictions are imposed here, and all are within the scope of protection.

[0050] In some embodiments, the pivot component 500 may have a first region and a second region along its extending direction; the elastic component 600 may be connected to the first region, and the second region may be used to cooperate with the flexible screen 400. Through the above arrangement, the first region and the second region are alternately arranged along the extending direction (axial direction) of the pivot component 500, enabling the elastic component 600 to contact the flexible screen 400 in segments along the extending direction of the pivot component 500, thereby effectively improving off-center load adaptability and further enhancing the stability of the flexible screen 400.

[0051] In some embodiments, when the elastic member 600 is in contact with the flexible screen 400, the target portion may protrude from the outer surface of the pivot member 500; along the extending direction of the pivot member 500, the flexible screen 400 may have a first portion corresponding to the first region and a second portion corresponding to the second region, the first portion being in contact with the elastic member 600, and the second portion having a gap with the pivot member 500. That is, only the elastic member 600 is in contact with the flexible screen 400, and the pivot member 500 is in clearance fit with the flexible screen 400.

[0052] The pivot component 500 can be cylindrical or conical, and the elastic component 600 can be directly disposed on the outer surface of the pivot component 500. Since the elastic component 600 has a certain thickness, the target portion of the elastic component 600 (located on the side of the elastic component 600 facing away from the pivot component 500) protrudes from the outer surface of the pivot component 500. Alternatively, the outer surface of the pivot component 500 can have a groove structure, and the elastic component 600 can be partially embedded in this groove structure. Even if the elastic component 600 contacts the flexible screen 400 and undergoes elastic deformation, the elastic component 600 still has a portion located outside the groove structure, and the target portion of the elastic component 600 is located in this portion, ensuring that the target portion can protrude from the outer surface of the pivot component 500.

[0053] In other embodiments, when the elastic member 600 is in contact with the flexible screen 400, the target portion can be aligned with the outer surface of the pivot member 500. This allows the target portion to be smoothly connected to the outer surface of the pivot member 500. Specifically, when the elastic member 600 is in contact with the flexible screen 400, the outer surface of the combined structure of the elastic member 600 and the pivot member 500 is a flat arc surface structure, and the combined structure of the elastic member 600 and the pivot member 500 can be a cylinder or a cone, etc. Along the extending direction of the pivot member 500, the flexible screen 400 has a first portion corresponding to the first region and a second portion corresponding to the second region. The first portion contacts the elastic member 600, and the second portion contacts the pivot member 500. To achieve the above design, a groove can be provided on the outer surface of the pivot member 500, so that the elastic member 600 is partially embedded in the groove in its non-elastically deformed state, and is fully embedded in the groove when the elastic member 600 is in contact with the flexible screen 400 and elastically deformed.

[0054] The number of elastic components 600 can be at least two; the pivot component 500 has at least two first regions, and the at least two first regions are correspondingly connected to at least two elastic components 600. Through the above arrangement, the combined structure of the pivot component 500 and the elastic components 600 forms a multi-segment elastic support structure for the flexible screen 400, which further improves the off-center load adaptability, thereby improving the stability of the flexible screen 400 during changes in the form of the electronic device. For example, the above arrangement can effectively improve the stability of the flexible screen 400 as a rollable screen during its expansion and contraction.

[0055] In some embodiments, at least one first region may be disposed at a first end of the pivot component 500 and at least one first region may be disposed at a second end of the pivot component 500, wherein the first end and the second end of the pivot component 500 may be opposite to each other. That is, both the first end and the second end of the pivot component 500 have elastic members 600, such that the first edge of the flexible screen 400 corresponding to the first end of the pivot component 500 and the second edge corresponding to the second end of the pivot component 500 are in contact with the elastic members 600, thereby improving the flatness of the flexible screen 400 in the extension direction of the pivot component 500 (the arrangement direction of the first end and the second end of the pivot component 500).

[0056] like Figure 1 , Figure 2 and Figure 3 As shown, in the first embodiment, the main body may include a first body 100, a second body 200, and a third body 300. The second body 200 and the third body 300 are movable relative to the first body 100 along a first direction X. The flexible screen 400 may have a first end and a second end, which are able to move closer and further apart relative to each other along the first direction X. The pivot component 500 is rotatably engaged with the second body 200 and / or the third body 300. The target portion of the elastic component 600 can contact the area of ​​the flexible screen 400 located between the first end and the second end. The electronic device in this embodiment can be a double-sided telescopic rollable screen device.

[0057] It is understandable that during the movement of the second body 200 and the third body 300 relative to the first body 100 along the first direction X, the area supported by the pivot component 500 on the flexible screen 400 changes, so that the pivot component 500 can support different positions of the flexible screen 400, and the unfolded area of ​​the flexible screen 400 is adapted to the structural deformation of the main body.

[0058] In some embodiments, there may be two pivot components 500, one of which is rotatably engaged with the second body 200, and the other is rotatably engaged with the third body 300. The unfolded area of ​​the flexible screen 400 is the area supported between the two pivot components 500. Figure 1 As shown, the electronic device has a first form and a second form (such as...). Figure 3 (The solid line structure represents the first form, and the dashed line structure represents the second form). When the electronic device is in the first form, the unfolded area of ​​the flexible screen 400 is the first region; when the electronic device is in the second form, the unfolded area of ​​the flexible screen 400 is the second region, and the second region is larger than the first region. For example... Figure 2 As shown, Figure 2 This is a schematic diagram of an electronic device with at least a portion of the flexible screen 400 removed and in a second configuration. To maximize the screen-to-body ratio, a hinge component 500 is provided on the side of the second body 200 away from the third body 300, and a hinge component 500 is also provided on the side of the third body 300 away from the second body 200, thereby increasing the unfolded length of the flexible screen 400 in the first direction X.

[0059] In this embodiment, during the switching process between the first and second forms of the electronic device, both the first and second ends of the flexible screen 400 move relative to the first body 100. The first and second ends of the flexible screen 400 are located... Figure 1 , Figure 2 and Figure 3 The back side of the shown surface. Taking the switching of an electronic device from the first form to the second form as an example, because the two pivot components 500 are relatively far apart, the first end and the second end of the flexible screen 400 are relatively far apart, so that more of the flexible screen 400 can move to... Figure 1 , Figure 2 and Figure 3 The surface shown is located between two pivot components 500. Taking the switching of an electronic device from the second state to the first state as an example, because the two pivot components 500 are relatively close, the first end and the second end of the flexible screen 400 are relatively close, so that more of the flexible screen 400 can move to... Figure 1 , Figure 2 and Figure 3 The back side of the face shown.

[0060] In other embodiments, the number of pivot components 500 can be one. Taking the pivot component 500 rotating in conjunction with the second body 200 as an example, the first end of the flexible screen 400 can be relatively fixed to the third body 300. During the switching process between the first and second forms of the electronic device, the first end of the flexible screen 400 moves with the third body 300, and the second end also moves relative to the first body 100. The first and second ends of the flexible screen 400 are located at... Figure 1 , Figure 2 and Figure 3 The back side of the shown surface. Taking the switching of an electronic device from the first form to the second form as an example, because the hinge component 500 is moved away from the third body 300, the first and second ends of the flexible screen 400 are relatively moved away, so that more of the flexible screen 400 can move to... Figure 1 , Figure 2 and Figure 3 The surface shown is located between two hinge components 500. Taking the switching of an electronic device from the second form to the first form as an example, since the hinge component 500 is close to the third body 300, the first and second ends of the flexible screen 400 are relatively close, so that more of the flexible screen 400 can move to... Figure 1 , Figure 2 and Figure 3 The back side of the face shown.

[0061] In other embodiments where the number of pivot components 500 can be one, taking the pivot component 500 rotating with the second body 200 as an example, the first end of the flexible screen 400 can be fixed relative to the first body 100. The third body 300 has a support edge (such as a sliding edge that engages with the flexible screen 400) that slides with it. Figure 2 The third body 300 (located on the edge away from the second body 200) can also adjust the unfolded area of ​​the flexible screen 400.

[0062] like Figure 8 and Figure 9 As shown, in the second embodiment, the main body may include a first body 100 and a second body 200 that can move relative to each other along a first direction X. The flexible screen 400 may have a first end and a second end. The first end may be positioned and connected to the first body 100, and the second end may move along the first direction X with the first body 100. The rotating shaft component 500 may be rotatably disposed on the second body 200, and the target portion of the elastic component 600 may contact the area of ​​the flexible screen 400 located between the first end and the second end. The electronic device in this embodiment may be a rollable screen device that can extend and retract on one side.

[0063] Similarly, it can be understood that during the relative movement of the first body 100 and the second body 200 along the first direction X, the area supported by the pivot component 500 on the flexible screen 400 changes, so that the pivot component 500 can support different positions of the flexible screen 400, and the unfolded area of ​​the flexible screen 400 is adapted to the structural deformation of the main body.

[0064] like Figure 8 As shown, the electronic device has a first form and a second form. In the first form, the unfolded area of ​​the flexible screen 400 is the first region; in the second form, the unfolded area of ​​the flexible screen 400 is the second region, which is larger than the first region. Figure 9 As shown, Figure 2 This is a schematic diagram of an electronic device with at least a portion of the flexible screen 400 removed and in a second configuration. To maximize the screen-to-body ratio, a pivot component 500 is provided on the side of the second body 200 away from the first body 100 to increase the unfolded length of the flexible screen 400 in the first direction X.

[0065] In this embodiment, during the switching process between the first and second forms of the electronic device, the second end of the flexible screen 400 moves relative to the first body 100. The first and second ends of the flexible screen 400 are located at... Figure 8 and Figure 9 The back side of the shown surface. Taking the switching of an electronic device from the first form to the second form as an example, because the hinge component 500 is far away from the first body 100, the first end and the second end of the flexible screen 400 are relatively far apart, so that more of the flexible screen 400 can move to... Figure 8 and Figure 9 As shown in the diagram. Taking the switching of an electronic device from the second state to the first state as an example, because the hinge component 500 is close to the first body 100, the first end and the second end of the flexible screen 400 are relatively close, so that more of the flexible screen 400 can move to... Figure 8 and Figure 9 The back side.
