Description

Technical Field

[0001] This application relates to the field of electronic device technology, and in particular to a foldable terminal. Background Technology

[0002] With the development of smart terminal devices, users' demand for large-screen terminal devices is constantly increasing. To ensure portability, the concept of foldable terminals has emerged. Taking foldable phones as an example, foldable phones typically include a mid-frame, hinge, flexible inner screen, and outer screen. The mid-frame is the skeleton of the foldable phone, mainly providing structural support for the various parts of the phone. It connects to the hinge to ensure that the foldable phone can stably switch between folded and unfolded states. The outer screen allows users to view and operate the phone when it is folded. The flexible inner screen is the main display area of ​​the foldable phone, which can fold and unfold with the mid-frame under the action of the hinge.

[0003] In related technologies, in order to increase the size of the flexible inner screen after unfolding, double folding or multiple folding (more than two folds) is usually adopted. The mid-frame and flexible inner screen of the foldable phone will have multiple layers stacked in the thickness direction, resulting in a thicker overall foldable phone, making it difficult to achieve a thinner and lighter design, and affecting the user experience. Summary of the Invention

[0004] This application provides a foldable terminal. The foldable terminal of this application uses an embedded method to splice the middle frame together, so that when the middle frame and the flexible display screen inside it are not stacked in multiple layers along the thickness direction when folded. Therefore, this application effectively reduces the thickness of the foldable terminal when folded, thereby achieving the requirement of a thinner and lighter foldable terminal.

[0005] This application provides a foldable terminal. The foldable terminal in the embodiments of this application adopts a double-fold or multi-fold (referring to more than two folds) design. This article uses a horizontal two-fold fold as an example for illustration, but a vertical two-fold fold can also be used, etc. This application does not limit this.

[0006] Specifically, the folding terminal includes: a first structural component, a second structural component, a third structural component, and a first display screen. The second structural component is rotatably connected to one side of the first structural component via a first pivot mechanism, and the third structural component is connected to the other side of the first structural component via a second pivot mechanism; that is, the second and third structural components are located on opposite sides of the first structural component. The first display screen includes a first display portion, a second display portion, and a third display portion, which are also located on opposite sides of the first display portion. The first display portion is located on the first structural component, the second display portion is located on the second structural component, and the third display portion is located on the third structural component.

[0007] Under the above structural layout, the second structural member can rotate relative to the first pivot mechanism along the first direction (the first folding point of the folding terminal), and the third structural member can rotate relative to the second pivot mechanism along the second direction (the second folding point of the folding terminal), so that the folding terminal of this embodiment is in a folded state, with the first and second directions being opposite; or, the second structural member can rotate relative to the first pivot mechanism along the second direction, and the third structural member can rotate relative to the second pivot mechanism along the first direction, so that the folding terminal of this embodiment is in an unfolded state.

[0008] In the unfolded state, the first display screen is located on the same side of the folding terminal, and the first structural component, the second structural component, and the third structural component jointly support the first display screen;

[0009] In the folded state, along the third direction, the second display portion is stacked on the first display portion, and the third display portion is stacked on the first display portion; along the fourth direction, the second display portion and the third display portion are spaced apart or attached together, and at least a portion of the third structural member is spaced apart or attached together with the second structural member; the third direction is perpendicular to the fourth direction and is consistent with the thickness direction of the folded terminal.

[0010] Specifically, the second and third structural components fold towards the first structural component in opposite directions to switch the foldable terminal to a folded state. At this time, at least a portion of the third structural component is spaced apart from or attached to the second structural component along a fourth direction (e.g., laterally). That is, at least a portion of the third structural component and the second structural component are laterally joined together, rather than being directly stacked along the thickness direction (i.e., the third direction) of the foldable terminal. Simultaneously, the third display portion located on the third structural component and the second display portion located on the second structural component are spaced apart or attached laterally; that is, the folded third and second display portions are also not directly stacked along the thickness direction (i.e., the third direction). Therefore, with the above-mentioned optimized structural layout of the foldable terminal, the overall thickness of the first, second, and third mid-frames and the flexible display screen after folding is reduced, making the foldable terminal thinner and lighter, resulting in better product performance and a better user experience.

[0011] Furthermore, in the folded state described above, along the thickness direction (i.e., the third direction), the third display portion and the second display portion are both stacked on top of the first display portion. That is, the first, second, and third display portions of the first display screen are enclosed internally by the first, second, and third structural components. At this time, along the fourth direction and with the first display screen as the boundary, the folded terminal presents a structure similar to a double layer. One layer is the third and second structural components assembled as described above, and the other layer is the first structural component that does not participate in the folding movement. This double-layer structure effectively achieves the thinning of the folded terminal in the folded state.

[0012] In some possible implementations, the folding terminal further includes: a second display screen; the second structural component includes a first part and a second part connected to each other, the first part being rotatably connected to a first rotating shaft mechanism, the second part having a first receiving portion, the second display screen being disposed in the second part and located in the first receiving portion, and the second display screen and the second display portion being located on opposite sides of the second part;

[0013] The third structural component includes a third part and a fourth part connected to each other. The third part is rotatably connected to the second rotating shaft mechanism. The third display part is disposed in the third part, and the fourth part has a second receiving portion.

[0014] In the folded state, the fourth part is housed in the first receiving part, the third part and the second part are spaced apart or attached to each other along the fourth direction, and the second display screen is housed in the second receiving part.

[0015] Using the above technical solution, firstly, the second structural component includes a first part and a second part, and the third structural component includes a third part and a fourth part. The first part is connected to a first rotating shaft mechanism, and the third part is connected to a second rotating shaft mechanism. The second part has a first receiving portion for accommodating the fourth part, so that in the folded state, the fourth part of the third structural component can be embedded into the first receiving portion in the second part of the first structural component. This allows the second and third structural components to be folded using an embedded splicing method rather than a complete stacking, achieving a thinner and lighter foldable phone in the folded state.

[0016] Secondly, the foldable terminal in this application embodiment also includes a second display screen (also referred to as an external screen) for user operation in the folded state. When the foldable terminal is in the folded state, the user can view and operate the terminal device through the second display screen. For example, the user can use the second display screen to view notifications, answer calls, take photos or record videos, etc., improving the portability of the foldable terminal and enhancing the user experience. Furthermore, the second display screen is disposed in the second part of the second structural member, and the fourth part of the third structural member is provided with a second receiving portion for accommodating the second display screen. That is to say, in the folded state, the second display screen can be embedded into the fourth part, thereby reducing the thickness of the foldable terminal and also improving the grip feel.

[0017] In some possible implementations, the second display screen includes a display surface, and the fourth part includes a first surface. In the folded state, the display surface is lower than the first surface, or the display surface is flush with the first surface.

[0018] By adopting the above technical solution, in the above folded state, when the display surface of the second display screen is lower than the first surface of the fourth part, that is, the second display screen embedded in the second receiving part of the fourth part is lower than the fourth part, thereby reducing the overall thickness of the folded terminal after folding, and also reducing the risk of accidental touch of the second display screen. Moreover, the fourth part, which is higher than the second display screen, can also provide additional protection for the second display screen, reducing wear and damage.

[0019] In the aforementioned folded state, when the display surface of the second display screen is flush with the first surface of the fourth part, the visual continuity of the folded terminal in the folded state can be improved, resulting in a smooth and neat aesthetic.

[0020] In some possible implementations, the display surface of the second display is higher than the first surface of the fourth part.

[0021] In some possible implementations, the first receiving portion includes a first recess and a second recess, with the second display screen located between the first and second recesses; the fourth portion includes a first convex portion and a second convex portion located on both sides of the second receiving portion; wherein, in the folded state, the first convex portion is received in the first recess, and the second convex portion is received in the second recess.

[0022] In some possible implementations, the first recess includes a first bottom wall, the second recess includes a second bottom wall, the first protrusion includes a second surface, the second protrusion includes a third surface, and the second surface, the third surface and the first surface of the fourth part are located on opposite sides; in the folded state, along the third direction, the second surface is spaced apart from or fitted to the first bottom wall, and the third surface is spaced apart from or fitted to the second bottom wall.

[0023] In some possible implementations, the second receiving portion includes a groove that extends through the fourth portion in a third direction and through the edge of the fourth portion in a fourth direction.

[0024] In some possible implementations, the second display screen includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall; the first portion includes a fifth sidewall; wherein,

[0025] Along the fifth direction, the first sidewall and the second sidewall are arranged opposite to each other; along the fourth direction, the third sidewall and the fourth sidewall are arranged opposite to each other; the fourth sidewall is connected to the fifth sidewall of the first part; the fifth direction is perpendicular to the fourth direction.

[0026] The first bottom wall, the first side wall, and the fifth side wall define the first recess, and the second side wall, the second bottom wall, and the fifth side wall define the second recess.

[0027] In some possible implementations, the groove includes a first inner wall, a second inner wall, and a third inner wall. Along the fifth direction, the first inner wall and the second inner wall are disposed opposite to each other, and the third inner wall is connected between the first inner wall and the second inner wall.

[0028] In the folded state, the first sidewall is spaced apart from or fitted to the first inner wall, the second sidewall is spaced apart from or fitted to the second inner wall, and the third sidewall is spaced apart from or fitted to the third inner wall.

[0029] In some possible implementations, the second receiving portion includes a through groove along a third direction, the through groove penetrating the fourth portion, and along a fifth direction and the fourth direction, the through groove does not penetrate the edge of the fourth portion; the fifth direction is perpendicular to the fourth direction.

[0030] In some possible implementations, the through groove includes a fourth inner wall, a fifth inner wall, a sixth inner wall, and a seventh inner wall connected together, with the fourth inner wall and the fifth inner wall arranged opposite each other along the fifth direction, and the sixth inner wall and the seventh inner wall arranged opposite each other along the fourth direction;

[0031] The second display screen includes a sixth sidewall, a seventh sidewall, an eighth sidewall, and a ninth sidewall. Along the fifth direction, the sixth and seventh sidewalls are arranged opposite to each other, and along the fourth direction, the eighth and ninth sidewalls are arranged opposite to each other.

[0032] In the folded state, the sixth side wall is spaced apart from or fitted to the fourth inner wall, the seventh side wall is spaced apart from or fitted to the fifth inner wall, the eighth side wall is spaced apart from or fitted to the sixth inner wall, and the ninth side wall is spaced apart from or fitted to the seventh inner wall.

[0033] In some possible implementations, the folding terminal further includes: a connector, which is connected to the second part and is part of the first receiving part, and a second display screen is disposed on the connector.

[0034] In some possible implementations, the second part is provided with a connecting slot for the connector to engage. The second display screen engages with the middle frame via the connecting slot, improving the reliability of the connection between the second display screen and the middle frame.

[0035] In some possible implementations, the connector is glued or magnetically attached to the second part.

[0036] In some possible implementations, the first display screen further includes: a first bendable portion and a second bendable portion, the first bendable portion being connected between the first display portion and the second display portion and corresponding to a first pivot mechanism, and the second bendable portion being connected between the first display portion and the third display portion and corresponding to a second pivot mechanism.

[0054] This application provides a foldable terminal. It can be understood that the foldable terminal is a smart terminal device with folding function. Specifically, the foldable terminal in the embodiments of this application includes, but is not limited to, foldable mobile phones, tablet computers, e-book readers, personal computers (PCs), laptops, personal digital assistants (PDAs), notebooks, in-vehicle devices, and other electronic devices that need to be folded.

[0055] Meanwhile, this application does not impose any special restrictions on the specific form of the above-mentioned electronic device. For example, the above-mentioned electronic device can be designed as any one of the following: horizontal double-fold form, vertical double-fold form, horizontal multi-fold form, and vertical multi-fold form. For ease of explanation, the following description takes a foldable mobile phone with a horizontal double-fold form as an example.

[0056] refer to Figure 1a and Figure 1b , Figure 1a A schematic diagram of a foldable mobile phone 1000 provided in some embodiments of this application is shown. Figure 1b A schematic diagram of the folded state of a foldable mobile phone 1000 provided in some embodiments of this application is shown.

[0057] like Figure 1a As shown, Figure 1a The foldable phone 1000 shown is in a transition state from an unfolded state to a folded state. At this time, the foldable phone 1000 is roughly Z-shaped. The foldable phone 1000 includes a first middle frame 1100, a second middle frame 1200, a third middle frame 1300, a flexible display screen 1200 (also called a "flexible foldable screen"), and two hinges (first hinge 1400 and second hinge 1500).

[0058] The first middle frame 1100 and the second middle frame 1200 are rotatably connected by the first pivot 1400, and the third middle frame 1300 and the second middle frame 1200 are connected by the second pivot 1500.

[0059] The flexible display screen 1200 includes a first flexible screen 1210, a second flexible screen 1220, and a third flexible screen 1230 connected to each other. Specifically, the first flexible screen 1210 is disposed in the first middle frame 1100, the second flexible screen 1220 is disposed in the second middle frame 1200, and the third flexible screen 1230 is disposed in the third middle frame 1300.

[0060] Furthermore, the foldable phone 1000 along Figure 1a Folding can continue in direction A (e.g., the thickness direction of the foldable phone 1000) as shown, thus enabling switching to... Figure 1b The folded state shown should be noted that... Figure 1b The first and second rotating shafts are not shown.

[0061] like Figure 1b As shown, in the foldable phone 1000 in the folded state, the first mid-frame 1100 and the first flexible screen 1210, the second mid-frame 1200 and the second flexible screen 1220, and the third mid-frame 1300 and the third flexible screen 1230 are in the thickness direction of the foldable phone 1000 (e.g., ...). Figure 1b A six-layer stack is generated along direction A (as shown in the diagram), for example, in Figure 1b In the design, the first mid-frame 1100, the first flexible screen 1210, the second flexible screen 1220, the second mid-frame 1200, the third mid-frame 1300, and the third flexible screen 1230 are stacked sequentially along the A1 direction, with the third flexible screen 1230 being used for viewing and operation by the user. It can be seen that the foldable phone 1000, which produces these six stacked layers, is relatively thick, which may affect the user's grip during use.

[0062] To solve this technical problem, refer to Figure 2a This application provides another foldable phone 100, in which two mid-frames (e.g., the second mid-frame 300 and the third mid-frame 500 described below) are spliced ​​together in an embedded manner in the folded state, instead of using the traditional multi-layer stacking method (e.g. Figure 1b (As shown). Based on this, the overall thickness of the foldable phone 100 in the folded state of this application embodiment is reduced, effectively achieving the thinness and lightness of the foldable phone 100 and improving the user's grip.

[0063] The foldable mobile phone 100 of this application is described below with reference to the accompanying drawings and specific embodiments.

[0064] Example 1

[0065] refer to Figure 2a and Figure 2b , Figure 2a A three-dimensional schematic diagram of the unfolded state of the foldable mobile phone 100 provided in an embodiment of this application is shown. Figure 2bA three-dimensional schematic diagram of the foldable mobile phone 100 provided in the embodiment of this application in its folded state is shown.

[0066] in, Figure 2a and Figure 2b The folding phone 100 shown is a horizontal two-fold design, that is, the left and right sides of the folding phone 100 fold towards the middle, but this is only one possible implementation method, and the embodiments of this application do not limit it.

[0067] For ease of subsequent description, before describing the specific structure of the foldable phone 100, this application embodiment first exemplarily defines the X, Y, and Z directions. For example... Figure 2a and Figure 2b As shown, the Y direction is the length direction (i.e., horizontal) of the foldable phone 100 when it is normally placed, which can also be understood as the direction in which the user holds the foldable phone 100; the X direction is the width direction of the foldable phone 100 when it is normally placed, which can also be understood as the direction perpendicular to the user's holding direction; the Z direction is the thickness direction of the foldable phone 100 when it is normally placed. The X, Y, and Z directions intersect each other. The following explanation will use an example where the X, Y, and Z directions are mutually perpendicular.

[0068] It should be further clarified that the mutual perpendicularity in this application is not absolute perpendicularity. Approximate perpendicularity due to processing and assembly errors (e.g., the included angle between two structural features is 89.9°) is also within the scope of mutual perpendicularity in this application. The limitation of mutual perpendicularity will not be repeated below.

[0069] In this embodiment of the application, the foldable phone 100 includes: a first mid-frame 200 (also referred to as a first structural component), a second mid-frame 300 (also referred to as a second structural component), a first pivot mechanism 400, a third mid-frame 500 (also referred to as a third structural component), a second pivot mechanism 600, and a flexible display screen 700.

[0070] like Figure 2a As shown, along the length direction of the foldable phone 100 (e.g., the fourth direction, such as...) Figure 2a (as shown in the Y direction) and towards the direction of the third middle frame 500 on the right (e.g.) Figure 2a As shown in the Y2 direction (in the diagram), the second middle frame 300, the first rotating shaft mechanism 400, the first middle frame 200, the second rotating shaft mechanism 600, and the third middle frame 500 are arranged sequentially. It can be seen that the first middle frame 200 is located in the middle position, and the second middle frame 300 is connected to one side of the first middle frame 200 via the first rotating shaft mechanism 400 (e.g., ...). Figure 2a The third middle frame 500 is rotatably connected to the left side of the first middle frame 200 via the second rotating shaft mechanism 600 (e.g., the left side of the Y1 direction). Figure 2aRotational connection (to the right of the Y2 direction).

[0071] The first middle frame 200, the second middle frame 300, and the third middle frame 500 constitute the supporting skeleton of the foldable phone 100, used to install the flexible display screen 700, battery panel, battery, and other electronic components (not shown in the figure). Specifically, the first middle frame 200, the second middle frame 300, the third middle frame 500, the first hinge mechanism 400, and the second hinge mechanism 600 are covered by the flexible display screen 700. The flexible display screen 700 can be an organic light-emitting diode (OLED) screen, a micro organic light-emitting diode (micro organic light-emitting diode) screen, a quantum dot light-emitting diode (QLED) screen, a liquid crystal display (LCD), etc.

[0072] Thus, the second middle frame 300 and the third middle frame 500 can rotate relative to the first pivot mechanism 400 and the second pivot mechanism 600, respectively, to drive the flexible display screen 700 to fold or unfold.

[0073] In other words, such as Figure 2a As shown, the second middle frame 300 located on the left can move along the first direction (such as...). Figure 2a The third middle frame 500, located on the right side, can rotate relative to the first rotating shaft mechanism 400 in the E direction shown in the diagram. Simultaneously, the third middle frame 500 can rotate along the second direction (e.g., the direction indicated by E). Figure 2a The folding phone 100 can rotate relative to the second pivot mechanism 600 in the direction F shown in the diagram, thereby enabling the folding phone 100 to be in such a position as Figure 2b The folded state shown.

[0074] like Figure 2b As shown, when the foldable phone 100 is in the folded state, the second middle frame 300 can move along the second direction (e.g., Figure 2b The third middle frame 500, after being folded, can rotate relative to the first pivot mechanism 400 in the F direction (as shown in the diagram). Simultaneously, the folded third middle frame 500 can rotate along the first direction (e.g., the direction indicated by F). Figure 2b The folding phone 100 rotates relative to the second pivot mechanism 600 in the direction E shown in the diagram, so that the folding phone 100 is in the position as shown in the diagram. Figure 2a The unfolded state is shown. The first and second directions are opposite, and both directions are set around the X direction (e.g., the fifth direction described later).

[0075] Continue to refer to Figure 2a and Figure 2bThe aforementioned second middle frame 300 includes a first portion 310 and a second portion 320, exemplarily, along a fourth direction (such as...). Figure 2a and Figure 2b (As shown in the Y direction), the size of the first part 310 is smaller than the size of the second part 320. For example... Figure 2a As shown, the first part 310 is rotatably connected to the first rotating shaft mechanism 400, and the second part 320 is connected to one side of the first part 310 (e.g., Figure 2a (the side indicated by the Y1 direction), and the second part 320 has a first receiving part 321.

[0076] Meanwhile, the aforementioned third middle frame 500 includes a third portion 510 and a fourth portion 520 connected together, exemplarily, along the fourth direction (such as... Figure 2a and Figure 2b (As shown in the Y direction), the size of the third part 510 is smaller than the size of the second part 520. For example... Figure 2a As shown, the third part 510 is rotatably connected to the second rotating shaft mechanism 600, the third display part 703 is disposed on the third part 510, and the fourth part 520 is connected to one side of the third part 510 (i.e., Figure 2a (The side indicated by the Y2 direction). Furthermore, the aforementioned first receiving portion 321 is used for, for example... Figure 2b The folded state shown is for accommodating the fourth part 520.

[0077] Continue to refer to Figure 2a and Figure 2b The foldable phone 100 in this embodiment also includes a second display screen 800, which, exemplarily, is the outer screen of the foldable phone 100. It can be seen that the second display screen 800 is disposed on the second mid-frame 300. Specifically, the second display screen 800 is disposed in the second portion 320 and located in the first receiving portion 321.

[0078] In addition, such as Figure 2a As shown, the fourth portion 520 of the third middle frame 500 also has a second receiving portion 521. In the case of... Figure 2b In the folded state shown, the second display screen 800 is housed in the second receiving portion 521.

[0079] Continue to refer to Figure 2a and Figure 2b The aforementioned fourth part 520 includes a first protrusion 523 and a second protrusion 524, along... Figure 2a In the X direction shown, the first protrusion 523 and the second protrusion 524 are located on both sides of the second receiving portion 521.

[0080] like Figure 2a As shown, the first receiving portion 321 includes a first recess 3211 and a second recess 3212, along... Figure 2a In the X direction shown, the first recess 3211 and the second recess 3212 are arranged opposite to each other, and the second display screen 800 is located between the first recess 3211 and the second recess 3212.

[0081] Continue to refer to Figure 2a and Figure 2b Furthermore, the aforementioned flexible display screen 700 includes: a first display portion 701, a second display portion 702, a third display portion 703, a first bendable portion 704, and a second bendable portion 705. Wherein, as... Figure 2a As shown, along the fourth direction and away from the aforementioned first receiving portion 321 (e.g.) Figure 2a (As shown in the Y2 direction), the second display portion 702, the first bendable portion 704, the first display portion 701, the second bendable portion 705 and the third display portion 703 are arranged in sequence.

[0082] As can be seen, the first display portion 701 is located in the middle and is positioned within the aforementioned first frame 200, while the second display portion 702 is located to the left of the first display portion 701 (e.g., Figure 2a The second display portion 702 is located on the side indicated by the Y1 direction and is disposed in the first portion 310 and the second portion 320, and the second display portion 702 is located on opposite sides of the second display screen 800; the third display portion 703 is located to the right of the first display portion 701 (e.g., on the right side of the first display portion 701). Figure 2a (The side pointed to by the Y2 direction) and set in the third part 510 of the third middle frame 500 mentioned above.

[0083] The first bendable portion 704 is connected between the first display portion 701 and the second display portion 702 and corresponds to the first pivot mechanism 400. The second bendable portion 705 is connected between the first display portion 701 and the third display portion 703 and corresponds to the second pivot mechanism 600.

[0084] Based on the above structural arrangement, refer to Figure 2a In the unfolded state of the foldable phone 100 of this application embodiment, the flexible display screen 700 is located on the same side of the foldable phone 100. For example, the flexible display screen 700 is located on the side of the foldable phone 100 along the Z1 direction, and the first middle frame 200, the second middle frame 300 and the third middle frame 500 jointly support the flexible display screen 700.

[0085] refer to Figure 2b and combined Figure 2a In the foldable phone 100 of this application embodiment, when folded, it can be seen that the first protrusion 523 is accommodated in the first recess 3211, and the second protrusion 524 is accommodated in the second recess 3212. Meanwhile, along a third direction (e.g.) Figure 2b (shown in the Z direction), the second display portion 702 is superimposed on one side of the first display portion 701 (e.g., in the Z direction). Figure 2b (On the side indicated by the Z1 direction), the third display portion 703 is also superimposed on the same side of the first display portion 701. Along the fourth direction (e.g. Figure 2b (As shown in the Y direction), the second display portion 702 and the third display portion 703 are spaced apart, and correspondingly, the third portion 510 of the third middle frame 500 and the second portion 320 of the second middle frame 300 are spaced apart.

[0086] refer to Figure 2a and Figure 2b Based on the folding design described above, at least the following technical effects can be achieved: the second middle frame 300 and the third middle frame 500 fold towards the first middle frame 200 in opposite directions, so that the folding phone 100 switches to the folded state. At this time, the third part 510 in the third middle frame 500 and the second part 320 in the second middle frame 300 are spaced apart along the fourth direction (lateral direction); the fourth part 520 in the third middle frame 500 is embedded in the first receiving portion 321 of the first part 310 of the second middle frame 300, that is, the first... The first protrusion 523 of the fourth part 520 is embedded in the first recess 3211 of the first receiving part 321, and the second protrusion 524 of the fourth part 520 is embedded in the second recess 3212 of the first receiving part 321. Simultaneously, the second display screen 800 in the second middle frame 300 is embedded in the second receiving part 521 of the third middle frame 500. That is, the third middle frame 500 and the second middle frame 300 are joined together by embedding, rather than being directly stacked as a whole along the thickness direction (i.e., the third direction) of the foldable phone 100. At the same time, the third display part 703 in the third middle frame 500 and the second display part 702 in the second middle frame 300 are spaced apart or attached together; that is, the third display part 703 and the second display part 702 after folding are not stacked as a whole along the third direction. For example, "overall stacking" can be understood as the stacking of structural components layer by layer, and the overall thickness of the resulting stacked structure is the sum of the thicknesses of each layer of structural components.

[0087] Therefore, with the above-mentioned structural layout optimization of the foldable terminal 100 in this application embodiment, the overall thickness of the first middle frame 200, the second middle frame 300, the third middle frame 500, and the flexible display screen 700 after folding is reduced, thereby making the foldable terminal 100 thinner and lighter, and achieving better product performance and consumer user experience.

[0088] Furthermore, in the folded state described above, along the third direction, the third display portion 703 and the second display portion 702 are both stacked on the first display portion 701. That is, the first display portion 701, the second display portion 702, and the third display portion 703 (i.e., the flexible display screen 700) are wrapped inside by the first middle frame 200, the second middle frame 300, and the third middle frame 500. At this time, along the fourth direction and with the flexible display screen 700 as the boundary, the folded terminal 100 presents a structure similar to a double layer.

[0089] Using the flexible display screen 700 as the boundary (e.g.) Figure 2b (as shown by dashed lines m and n), for example, first referencing dashed line m, along a third direction and away from the first middle frame 200 (such as... Figure 2b (As shown in the Z1 direction), one of the layers of the similar double-layer structure is: the third middle frame 500 and the second middle frame 300, which are spliced ​​together by the above-mentioned embedded components.

[0090] Referring again to the dashed line n, along the third direction and towards the first middle frame 200 (e.g. Figure 2b In the Z2 direction shown, the other layer in the similar double-layer structure is the first middle frame 200. Therefore, this double-layer-like structure effectively achieves the thinning of the foldable terminal 100 in the folded state.

[0091] The embodiments of the foldable phone described above will now be described in further detail with reference to the accompanying drawings.

[0092] refer to Figure 2a and Figure 2b In some possible implementations, the second display screen 800 described above includes a display surface 801 for displaying information for user operation. The fourth portion 520 includes a first surface 522. When the foldable phone 100 is in a folded state, as... Figure 2b As shown, the display surface 801 of the second display screen 800 is flush with the first surface 522 of the fourth portion 520. In some possible embodiments, although not shown in the figure, it is understood that the display surface 801 may also be lower than the first surface 522 of the fourth portion 520.

[0093] refer to Figure 3a and Figure 3b , Figure 3a A top view of the foldable phone 100 provided in this application embodiment in a folded state is shown. Figure 3b The image shows a bottom view of the foldable phone 100 provided in the embodiment of this application in its folded state.

[0094] As you can see, Figure 3aThe second display screen 800 shown above is rectangular, but the shape of the second display screen 800 is not limited in this embodiment. For example, the second display screen 800 can also be any shape such as circular, triangular, or trapezoidal.

[0095] For example, the second display screen 800 and the second middle frame 300 in this application embodiment can be connected by means of adhesive, mechanical fixation, magnetic attraction, embedding, splicing, etc. This application embodiment does not impose specific restrictions on the connection method of the second display screen 800.

[0096] For example, from a functional perspective, the second display screen 800 described in the embodiments of this application can be any one or more of the following: a notification screen, a touch screen, a full-function screen, or a smart screen; from a size perspective, the second display screen 800 in the embodiments of this application can be, for example, a small screen, a medium screen, a large screen, or an extra-large screen. The embodiments of this application do not impose specific limitations on the function and size of the second display screen 800.

[0097] refer to Figure 4 , Figure 4 A schematic diagram of the structure of the foldable mobile phone 100 provided in the embodiment of this application in the folded state is shown.

[0098] In some possible implementations, combined Figure 2a and Figure 4 The second receiving portion 521 is a rectangular groove 5211, see reference. Figure 4 and combined Figure 2a As can be seen, the groove 5211 is along the thickness direction of the foldable phone 100 (e.g., Figure 4 The rectangular groove 5211 extends through the fourth part 520 along the length direction of the folding phone 100 (e.g., the fourth direction, or, for example, the Z direction shown in the diagram). Figure 4 The Y2 direction shown in the figure runs through the edge of the fourth part 520.

[0099] For example, the groove 5211 includes a first inner wall 52111, a second inner wall 52112, and a third inner wall 52113 connected in sequence. It can be seen that along... Figure 4 In the X direction shown, the first inner wall 52111 and the second inner wall 52112 are arranged opposite to each other, and the third inner wall 52113 extends along the X direction and connects between the first inner wall 52111 and the second inner wall 52112.

[0100] For example, the second display screen 800 further includes a first sidewall 802, a second sidewall 803, a third sidewall 804, and a fourth sidewall 805 connected in sequence. Along Figure 4 In the X direction shown, the first sidewall 802 and the second sidewall 803 are arranged opposite each other, along the fourth direction (e.g. Figure 4(As shown in the Y direction), the third sidewall 804 and the fourth sidewall 805 are disposed opposite to each other. The fourth sidewall 805 is connected to the first portion 310 of the second middle frame 300 mentioned above.

[0101] Continue to refer to Figure 4 As can be seen, when the second display screen 800 is accommodated in the groove 5211, the first side wall 802 of the second display screen 800 corresponds to and is spaced apart from the first inner wall 52111, the second side wall 803 corresponds to and is spaced apart from the second inner wall 52112, and the third side wall 804 corresponds to and is spaced apart from the third inner wall 52113.

[0102] It should be noted that this is only one possible implementation. That is, although it is not shown in the figure, it can be understood that the first side wall 802 of the second display screen 800 can also correspond to and fit against the first inner wall 52111 of the groove 5211. Accordingly, the second side wall 803 corresponds to and fits against the second inner wall 52112, and the third side wall 804 corresponds to and fits against the aforementioned third inner wall 52113.

[0103] refer to Figure 4 and combined Figure 2a In some possible implementations, the first recess 3211 includes a first bottom wall 32111, and the second recess 3212 includes a second bottom wall 32121. The first protrusion 523 includes a second surface 5231, and the second protrusion 524 includes a third surface (not shown in the figure). The second surface 5231, the third surface, and the first surface 522 of the fourth portion 520 (as shown in the figure) Figure 2b (As shown) is located on the opposite sides of the third middle frame 500.

[0104] In the folded state, along a third direction (e.g.) Figure 2b and Figure 4 (shown in the Z direction), second surface 5231 (as shown in the figure) Figure 2a (as shown) and the first bottom wall 32111 (as shown) Figure 2a As shown, the third surface and the second bottom wall 32121 are spaced apart or bonded together.

[0105] refer to Figure 4 and combined Figure 2a The first part 310 includes a fifth sidewall 311, the fifth sidewall 311 (as shown in the image) Figure 2a As shown) along the width direction of the folding phone 100 (e.g., the fifth direction, or, for example...). Figure 2a (as shown in the X direction). The fourth sidewall 805 of the aforementioned second display screen 800 (as shown in the X direction) extends. Figure 4 (As shown) is connected to the fifth sidewall 311 of the first part 310. The fifth direction is perpendicular to the fourth direction mentioned above.

[0106] As can be seen, the first bottom wall 32111, the first side wall 802, and the fifth side wall 311 define the aforementioned first recess 3211, and the second side wall 803, the second bottom wall 32121, and the fifth side wall 311 define the aforementioned second recess 3212. When the foldable phone 100 is in the folded state, the ends of the first protrusion 523 and the second protrusion 524 of the fourth portion 520 are respectively spaced apart from or fitted against the fifth side wall 311 in the lateral direction.

[0107] Furthermore, it should be noted that the specific structure of the first pivot mechanism 400 and the second pivot mechanism 600 is not limited in the embodiments of this application. As long as the first pivot mechanism 400 and the second pivot mechanism 600 can dynamically switch between the folded state and the unfolded state of the foldable phone 100, they are all within the protection scope of the embodiments of this application.

[0108] In summary, the foldable phone 100 of this application uses an embedded method to splice the second middle frame 300 and the third middle frame 500 together, so that the second middle frame 300 and the third middle frame 500 and the flexible display screen 700 inside them will not be stacked in multiple layers along the thickness direction. Therefore, this application effectively reduces the thickness of the foldable phone 100 in the folded state, thereby achieving the requirement of a thinner and lighter foldable phone 100.

Example 2

[0110] Figure 5a and Figure 5b Three-dimensional schematic diagrams of the unfolded state of the foldable mobile phone 100 in this embodiment 2 are shown respectively.

[0111] Referring to Example 1 Figure 2a , Figure 2b And the second embodiment of this example Figure 5a and Figure 5b As can be seen, the foldable phone 100 in both Embodiment 2 and Embodiment 1 includes a first middle frame 200, a second middle frame 300, a first pivot mechanism 400, a third middle frame 500, a second pivot mechanism 600, and a flexible display screen 700. Meanwhile, the second middle frame 300 also includes a first part 310 and a second part 320. The second part 320 has a first receiving portion 321, which is used to accommodate the fourth part 520 of the third middle frame 500. The third middle frame 500 also includes a third part 510 and a fourth part 520. The arrangement and connection methods of the components mentioned above are the same and will not be repeated here. The differences between Embodiment 1 and Embodiment 2 will be explained below.

[0112] Referring to Example 1 Figure 2a , Figure 2b And the second embodiment of this example Figure 5a and Figure 5bIt can be seen that the shape of the second display screen 800 in this second embodiment is different from that in the first embodiment, and the second receiving portion 521 in this second embodiment is set as a through groove, which is different from the groove in the first embodiment. Specifically:

[0113] First refer to Figure 5a , Figure 5a The exemplary second receiving portion is a rectangular first through groove 5212, which differs from the groove 5211 in Embodiment 1 in that it extends along the fourth direction (e.g., Figure 5a The Y direction shown in the figure) and along the fifth direction (as shown in the figure) Figure 5a (As shown in the X direction), the first through slot 5212 does not penetrate the edge of the fourth portion 520; correspondingly, the second display 800 is also configured as a smaller rectangular outer screen 8000. In the folded state, the first through slot 5212 can accommodate the rectangular outer screen 8000.

[0114] For example, the first through groove 5212 includes a fourth inner wall 52121, a fifth inner wall 52122, a sixth inner wall 52123, and a seventh inner wall 52124 connected to each other, along a fifth direction (e.g., Figure 5a The fourth inner wall 52121 and the fifth inner wall 52122 are arranged opposite each other along the fourth direction (as shown in the X direction). Figure 5a (shown in the Y direction), the sixth inner wall 52123 and the seventh inner wall 52124 are arranged opposite to each other.

[0115] Accordingly, the rectangular outer screen 8000 includes a sixth side wall 8100, a seventh side wall 8200, an eighth side wall 8300 and a ninth side wall 8400. Along the fifth direction, the sixth side wall 8100 and the seventh side wall 8200 are arranged opposite each other, and along the fourth direction, the eighth side wall 8300 and the ninth side wall 8400 are arranged opposite each other.

[0116] It is understood that, in the folded state, the sixth side wall 8100 is spaced apart from or fitted to the fourth inner wall 52121, the seventh side wall 8200 is spaced apart from or fitted to the fifth inner wall 52122, the eighth side wall 8300 is spaced apart from or fitted to the sixth inner wall 52123, and the ninth side wall 8400 is spaced apart from or fitted to the seventh inner wall 52124.

[0117] refer to Figure 5b In some possible implementations, Figure 5b The exemplary second receiving portion is a second through groove 5213 (circular through hole), which differs from the groove 5211 in Embodiment 1 in that it is along the fourth direction (e.g. Figure 5a(As shown in the Y direction), the second through slot 5213 does not penetrate the fourth portion 520; correspondingly, the second display screen 800 is also configured as a smaller circular outer screen 8001. In the folded state, the through hole 8213 can accommodate the circular outer screen 8001.

[0118] It should be noted that the shape of the through groove is not limited to the above-mentioned circles and rectangles, but can also be other shapes, such as hexagons, ellipses, etc.

[0119]

Example 3

[0120] Figures 6a to 6c Schematic diagrams are shown of the unfolded state of the foldable phone 100 in this embodiment three. Among them, Figures 6a to 6c The flexible display screen 700 is not shown in the image.

[0121] Refer to Example 2 Figure 5b And the third embodiment of this example Figures 6a to 6c As can be seen, compared with the foldable phone 100 of Embodiment 2, the connection method between the second display screen (taking the circular outer screen 8001 as an example) and the second middle frame 300 is different in Embodiment 3, and the number of second display screens is also different. The structural parts that are the same between Embodiment 3 and Embodiment 2 will not be described again. (See reference...) Figure 6a In some possible implementations, the folding terminal also includes a connector 900, the top of which is provided with two circular outer screens 8001, such as... Figure 6a As shown, two circular outer screens 8001 are spaced apart. It should be noted that the number of circular outer screens 8001 is not specifically limited in this embodiment of the application; for example, one, three, or other numbers of circular outer screens 8001 can also be provided. The second part 320 of the second frame 300 is provided with a connecting groove 322, which is used for the connector 900 to be embedded and engaged.

[0122] Accordingly, in Example 2 Figure 5b The implementation shown differs from that of the one described. Figure 6a The exemplary illustration shows two second through slots 5213, which are spaced apart. In the folded state, the second through slots 5213 can accommodate the corresponding circular outer screen 8001.

[0123] refer to Figure 6b and Figure 6c In some possible implementations, the connector 900 may also be directly connected to the second part 320. Specifically, along the fourth direction (e.g. Figure 6b and Figure 6c (As shown in the Y direction), two circular outer screens 8001 are disposed on the connector 900 and spaced apart from each other. Figure 6cAs shown, by way of example, the connector 900 can be fixed to the second part 320 by means of adhesive or magnetic attraction, and the connector 900 constitutes part of the first receiving part 321 (i.e., the bottom wall of the first receiving part 321).

[0124]

Example 4

[0125] Figure 7a This is a three-dimensional schematic diagram of the unfolded state of the foldable mobile phone 100 provided in Embodiment Six of this application. Figure 7b A schematic diagram of the folded state of the foldable mobile phone 100 provided in Embodiment Six of this application is shown.

[0126] Referring to Example 1 Figure 2a and Figure 2b And the fourth embodiment of this example Figure 7a and Figure 7b It can be seen that the difference between this fourth embodiment and the foldable phone 100 in the first embodiment lies in the fact that, along the fourth direction (e.g., Figure 7b (shown in the Y direction), the first part 310, the second part 320, the third part 510 and the fourth part 520 have different sizes, and the second part 320 of the second middle frame 300 and the third part 510 of the third middle frame 500 are fitted together.

[0127] refer to Figure 7a and Figure 7b Specifically, this application does not limit the size of the first part 310, the second part 320, the third part 510, and the fourth part 520. For example, in this fourth embodiment, along the fourth direction, the size of the first part 310 of the second middle frame 300 is larger than the size of the second part 320, and the size of the third part 510 of the third middle frame 500 is larger than the size of the second part 520.

[0128] Alternatively, in some possible implementations, the size of the first portion 310 of the second middle frame 300 is equal to the size of the second portion 320, and the size of the third portion 510 of the third middle frame 500 is equal to the size of the second portion 520. Meanwhile, in the folded state, along a third direction (e.g.) Figure 7b (As shown in the Z direction), the second display portion 702 is stacked on top of the first display portion 701, and the third display portion 703 is also stacked on top of the first display portion 701. Along the fourth direction (e.g., Figure 7b As shown in the Y direction, the second display portion 702 and the third display portion 703 are fitted together. Correspondingly, the third portion 510 of the third middle frame 500 is fitted with the second portion 320, and the fourth portion 520 is fitted with the first portion 310.

[0129] Example 5

[0130] Figure 8a This is a three-dimensional schematic diagram of the unfolded state of the folding phone provided in Embodiment 5 of this application. Figure 8a The image shows a flexible display screen 700. Figure 8b This paper shows a schematic diagram of the folded state of the foldable phone provided in Embodiment 5 of this application. Figure 8b The image shows a flexible display screen 700. Figure 8c This document shows a schematic diagram of the folded state of the foldable phone provided in Embodiment 5 of this application. Figure 8c The image shows a flexible display screen 700.

[0131] Compared with the foldable phone 100 in Embodiment 1, the difference in Embodiment 5 of this application is that the second part 320 does not have a first receiving part, and the fourth part 520 does not have a second receiving part for receiving the flexible display screen 700. On this basis, the second middle frame 300 and the third middle frame 500 are spaced apart or attached along the fourth direction to splice the second middle frame 300 and the third middle frame 500 together.

[0132] refer to Figure 8a and Figure 8b In some possible implementations, in the folded state, along a third direction (e.g.) Figure 8b (As shown in the Z direction), the second display portion 702 of the flexible display screen 700 is stacked on top of the first display portion 701, and the third display portion 703 of the flexible display screen 700 is also stacked on top of the first display portion 701. Along the fourth direction (e.g., Figure 8b As shown in the Y direction, the second display portion 702 and the third display portion 703 of the flexible display screen 700 are spaced apart. Simultaneously, the third portion 510 of the third middle frame 500 is spaced apart from the second portion 320, and the fourth portion 520 of the third middle frame is also spaced apart from the second portion 320. That is, in this fifth embodiment, the second middle frame 300 and the third middle frame 500 are spaced apart along the fourth direction to splice the second middle frame 300 and the third middle frame 500 together.

[0133] refer to Figure 8a and Figure 8c In some possible implementations, in the folded state, along a third direction (e.g.) Figure 8b (As shown in the Z direction), the second display portion 702 of the flexible display screen 700 is stacked on top of the first display portion 701, and the third display portion 703 of the flexible display screen 700 is also stacked on top of the first display portion 701. Along the fourth direction (e.g., Figure 8bAs shown in the Y direction, the second display portion 702 and the third display portion 703 of the flexible display screen 700 are attached together. At the same time, the second middle frame 300 and the third middle frame 500 are attached together along the fourth direction to splice the second middle frame 300 and the third middle frame 500 together.

[0134] It should be noted that another difference between the foldable phone 100 of Embodiment 5 and Embodiment 1 is that, in Embodiment 5, the fourth part 520 of the third middle frame 500 can also be provided with a flexible display screen 700. That is, the third display part 703 of the flexible display screen 700 is located in the third part 510 and the fourth part 520.

[0135] For example, although Figures 8a to 8c The second display screen 800 is not shown in the figure, but in Embodiment 5 of this application, the second display screen 800 can still be provided. For example, the second display screen 800 can be embedded in the second middle frame 300. The second display screen 800 can switch between the folded state and the unfolded state with the second middle frame 300. This application embodiment does not limit this.

[0136] With this technical solution, the second middle frame 300 and the third middle frame 500 are set apart or attached along the fourth direction, and the two do not make contact or stack along the thickness direction, which effectively reduces the overall thickness of the foldable phone 100.

[0137] In summary, in this embodiment of the foldable phone, the second mid-frame 300 and the third mid-frame 500 are spliced ​​together in an embedded manner, and the two are not stacked together as a whole along the thickness direction. At the same time, the third display portion 702 and the second display portion 703, which are wrapped inside by the second mid-frame 300, the third mid-frame 500 and the first mid-frame 200, are relatively spaced apart or attached to each other. Therefore, compared with the traditional solution that produces multiple layers after folding, the foldable terminal 100 of this application achieves effective thinning in the folded state, thereby realizing the development of lightweight and thin development.
