[0024] Some embodiments of this disclosure will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. Various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will become apparent upon understanding this disclosure. For example, the order of operations described herein is merely illustrative and is not limited to those orders set forth herein, but can be changed as will become apparent upon understanding this disclosure, except for operations that must be performed in a particular order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0025] The embodiments described in the following examples of this disclosure are not representative of all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0026] Foldable electronic devices, due to their smaller single-sided frame, inherently suffer from insufficient heat dissipation. To ensure adequate heat dissipation, related technologies typically employ a graphite sheet along the hinge to conduct heat between the two parts of the foldable device, ensuring even heat distribution and improving overall cooling. Furthermore, to avoid affecting screen flatness, the graphite sheet is routed beneath the hinge. However, the area beneath the hinge contains numerous transmission structures, resulting in limited space for the graphite sheet to pass through, restricting its width and impacting its heat conduction capacity.

[0027] In view of this, some embodiments of the present disclosure provide a foldable electronic device that improves the heat conduction effect by extending a heat-conducting element through a support assembly located between the screen and the hinge, thereby increasing the width of the through-axis portion of the heat-conducting element.

[0028] Figure 1 This is a schematic diagram of the structure of a foldable electronic device according to some embodiments of the present disclosure. Figure 2 yes Figure 1 A cross-sectional view along direction A. Figure 3 yes Figure 1 A sectional view along direction B. For example... Figures 1 to 3 As shown, the foldable electronic device includes: a housing assembly 1, a flexible screen 2, a support assembly 4, and a heat-conducting component 3. The housing assembly 1 includes a pivot (not shown), and the housing assembly 1 is folded or unfolded relative to each other via the pivot. The flexible screen 2 is disposed on the housing assembly 1 and includes a bending area that covers the pivot. The support assembly 4 is connected to both the pivot and the flexible screen 2, and is located between the flexible screen 2 and the pivot, providing support for the bending area. The heat-conducting component 3 is disposed within the housing assembly 1 and spans both sides of the pivot, penetrating the support assembly 4 and being isolated from the flexible screen 2 by the support assembly 4.

[0029] The back of the flexible screen 2 is bonded to the housing assembly 1 with adhesive 13, allowing it to bend as the housing assembly 1 is folded or unfolded. A support assembly 4, connected to a pivot, corresponds to the bending area of ​​the flexible screen 2. Located between the flexible screen 2 and the pivot, the support assembly 4 supports the bending area of ​​the flexible screen 2, improving its flatness in the unfolded state. A heat-conducting component 3 extends through the support assembly 4, providing ample space to span both sides of the pivot, thus enhancing its thermal conductivity. Furthermore, the support assembly 4 isolates the heat-conducting component 3 from the flexible screen 2, preventing any impact on their flatness.

[0030] For example, by setting the heat-conducting component 3 through the support component 4, the problem of the heat-conducting component 3 deforming or floating upwards after long-term folding of the foldable electronic device base, thus lifting the flexible screen 2, can be solved. At the same time, it can also absorb the impact of the thickness tolerance of the heat-conducting component 3 on the crease of the flexible screen 2.

[0031] In some embodiments, the heat-conducting element 3 comprises sheet-like bendable graphite.

[0032] In some embodiments, the support assembly 4 includes a float plate and a support plate. The float plate is movably connected to a pivot. One side of the support plate is connected to the flexible screen 2, and the other side of the support plate faces the float plate. At least a portion of the heat-conducting element 3 is located between the float plate and the support plate.

[0033] During the folding or unfolding of the housing assembly 1, the rotating shaft moves. The floating plate, movably connected to the rotating shaft, shifts with the shaft's movement. For example, during the folding of the housing assembly 1, the floating plate provides storage space for the flexible screen 2 through displacement; or during the unfolding of the housing assembly 1, the floating plate shifts to a preset position to support the flexible screen 2. A support plate is provided on one side of the floating plate, which supports the flexible screen 2, further improving its flatness. Furthermore, no complex connecting or transmission mechanisms are needed between the support plate and the floating plate, allowing for a larger space between them for the heat-conducting component 3 to span both sides of the rotating shaft.

[0034] For example, the housing assembly 1 includes a first housing 11 and a second housing 12, which are connected by a pivot. The heat-conducting component 3 includes a first part, a second part, and a third part arranged sequentially. The first part is disposed within the first housing 11, the third part is disposed within the second housing 12, the second part covers the pivot, and the second part is located between the float plate and the support member.

[0035] By using a support plate and a floating plate, the problem of uneven light and shadow at the adhesive application point can be solved in related technologies where localized adhesive application on both sides of the graphite on the hinge or direct application of double-sided tape to attach the flexible screen 2 to the hinge floating plate is used. At the same time, the support plate can effectively absorb the impact of the floating plate's flatness on creases, especially the impact of localized unevenness on creases.

[0036] It should be noted that this disclosure does not specifically limit the structure and connection relationship of the floating plate. Those skilled in the art can configure the floating plate according to actual needs or specific pivot structure, so that the floating plate is connected to the pivot and can support the flexible screen 2.

[0037] like Figure 2 and Figure 3 As shown, in some embodiments, the floating plate includes a first floating plate 41, and the support piece includes a first support piece 42 that matches the first floating plate 41. In the unfolded state of the housing assembly 1, the heat-conducting element 3 at least partially covers the first floating plate 41. One side of the first support piece 42 is bonded to the screen, and the other side of the first support piece 42 abuts against the heat-conducting element 3, or abuts against both the heat-conducting element 3 and the first floating plate 41 respectively. By providing a first support piece 42 that matches the first floating plate 41, the impact of unevenness on the support surface of the flexible screen 2 caused by the flatness, step difference, and tolerance of the heat-conducting element 3 on creases can be effectively resolved.

[0038] The first support plate 42 abuts against the first float plate 41, making the space between the first support plate 42 and the first float plate 41 larger for the heat-conducting component 3 to pass through, thereby improving the heat conduction performance of the heat-conducting component 3.

[0039] In some embodiments, there are two or more first float plates 41 to accommodate more complex shaft drive structures. Two or more first float plates 41 are provided corresponding to one first support plate 42 to eliminate the step difference between the two or more first float plates 41.

[0040] Figure 4 This is a schematic diagram illustrating the structure of the first buffer sheet 45 according to some embodiments of the present disclosure. Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the support component 4 further includes a first buffer sheet 45. The opposite sides of the first buffer sheet 45 are bonded to the flexible screen 2 and the first support sheet 42, respectively. The first buffer sheet 45 has multiple through holes 451. The first buffer sheet 45 has a certain amount of interference compression, further eliminating unevenness on the support surface of the flexible screen 2 caused by the flatness, step difference, and tolerance of the heat-conducting component 3 of the first floating plate 41. Furthermore, the design of the multiple through holes 451 allows the first buffer sheet 45 to stretch to a certain extent as the flexible screen 2 bends, avoiding affecting the bending force of the flexible screen 2.

[0041] In some embodiments, the support component 4 further includes a first double-sided adhesive 46. The first buffer sheet 45 is bonded to the first support sheet 42 via the first double-sided adhesive 46, and the width of the first double-sided adhesive 46 is smaller than the width of the first support sheet 42. While ensuring the bonding strength of the first double-sided adhesive 46, the first double-sided adhesive 46 is made as narrow as possible to reduce the bonding width between the first double-sided adhesive 46 and the first support sheet 42, thereby avoiding excessive bonding that could affect the bending of the flexible screen 2.

[0042] In some embodiments, the first float plate 41 has a groove on the side facing the first support plate 42. The groove provides clearance for the heat-conducting element 3 between the first float plate 41 and the first support plate 42. This is to avoid the problem of uneven support between the first float plate 41 and the first support plate 42 when the heat-conducting element 3 covers part of the first float plate 41.

[0043] In some embodiments, the floating plate further includes a second floating plate 43, and the support sheet further includes a second support sheet 44 that matches the second floating plate 43. In the unfolded state of the housing assembly 1, the heat-conducting element 3 covers a portion of the second floating plate 43, one side of the second support sheet 44 is bonded to the flexible screen 2, and the other side of the second support sheet 44 abuts against the heat-conducting element 3 and is bonded to the second floating plate 43. The heat-conducting element 3 covers the middle portion of the second floating plate 43, such as... Figure 2 As shown. The portion of the second floating plate 43 not covered by the heat-conducting component 3 is used for bonding to the second support plate 44, as shown. Figure 3 As shown, the space between the second support plate 44 and the second floating plate 43 is made larger so that the heat-conducting component 3 can pass through, thereby improving the thermal conductivity of the heat-conducting component 3.

[0044] In some embodiments, there are two second floating plates 43. When the housing assembly 1 is in the unfolded state, the two second floating plates 43 are symmetrically arranged about the first floating plate 41, so that the floating plate formed by the first floating plate 41 and the two second floating plates 43 is more adapted to the bending area of ​​the flexible screen 2 and improves the support effect.

[0045] In some embodiments, the support assembly 4 further includes a second double-sided adhesive 49. The second support sheet 44 is bonded to the second float plate 43 by the second double-sided adhesive 49, which is applied to the portion of the second float plate 43 not covered by the heat-conducting component 3. This is to prevent uneven support of the second float plate 43 on the second support sheet 44 when the heat-conducting component 3 covers the portion of the second float plate 43.

[0046] In some embodiments, the support assembly 4 further includes a second buffer sheet. The second buffer sheet 48 is disposed between the second support sheet 44 and the second float plate 43, and the second buffer sheet 48 is located at the edge of the second support sheet 44 near the first float plate 41.

[0047] On the side of the second support piece 44 facing the second floating plate 43, the outer side is bonded with the second double-sided adhesive 49, and the inner side is supported by the second buffer piece 48 to reduce the impact of unevenness of the support surface of the flexible screen 2 caused by the flatness, step difference, and tolerance of the heat-conducting component 3 of the second floating plate 43 on the creases. Furthermore, after prolonged closed creep of the flexible screen 2, the bending area of ​​the flexible screen 2 corresponding to the second floating plate 43 tends to arch upwards. The second buffer piece 48 supports the bottom inner side of the second support piece 44, avoiding direct fixing with double-sided adhesive / application. This effectively weakens the downward pull of the double-sided adhesive on the top of the second support piece 44 on the flexible screen 2, effectively solving the problem of surface imprints at the adhesive location of the flexible screen 2 and the impact of the floating plate's flatness on the creases, thus effectively improving the appearance of the bending area of ​​the flexible screen 2.

[0048] In some embodiments, the support component 4 further includes a third double-sided adhesive 47. The second support sheet 44 is bonded to the screen via the third double-sided adhesive 47, the width of which is smaller than the width of the second support sheet 44. While ensuring the adhesive strength of the third double-sided adhesive 47, it is made as narrow as possible to reduce the bonding width between the third double-sided adhesive 47 and the second support sheet 44, thereby preventing excessive bonding from affecting the bending of the flexible screen 2.

[0049] The third double-sided adhesive 47 extends through the length of the second support piece 44, effectively fixing the flexible screen 2 and preventing it from arching during bending.

[0050] In some embodiments, a preset gap L is provided between the second float plate 43 and the housing assembly 1, and at least a portion of the heat-conducting element 3 is bent and disposed within the preset gap L. By setting the preset gap L, deformation space is provided for the heat-conducting element 3 during bending, thereby improving the service life of the heat-conducting element 3.

[0051] The foldable electronic device of this disclosure, while ensuring the heat conduction capacity of the heat-conducting component 3, achieves the following: 1. Significantly reduces the impact of the upward arching of the heat-conducting component 3, the flatness of the pivot plate, or the step difference on the crease, effectively improving the consistency of the crease. 2. Overcomes the downward force of creep deformation after the flexible screen 2 is closed for a long time, effectively reducing the crease depth and ensuring that the crease depth remains within a shallow range even after long-term closed use. 3. Effectively reduces surface imprints at the adhesive location of the flexible screen 2, improving the overall appearance of the device. 4. Solves the problem of the risk of reverse arching when the flexible screen 2 is bent.

[0062] In the above detailed description, reference has been made to the accompanying drawings, which illustrate specific aspects of this disclosure by way of illustration. In this regard, terms indicating direction or positional relationship, such as “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential,” are used with reference to the orientation of the described figures. Since components of the described device can be positioned in multiple different orientations, directional terms are used for illustrative purposes and not for limitation. It should be understood that other aspects can be utilized and structural or logical changes can be made without departing from the concept of this disclosure. Therefore, the following detailed description should not be considered limiting.

[0063] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any of the associated listed items and any combination of any two or more; it should be understood that, unless otherwise expressly specified and limited, the terms "joining," "attaching," "mounting," "connecting," "linking," "fixing," etc., used in the embodiments of this disclosure should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral part; as a mechanical connection, an electrical connection, or a communicative connection; as a direct connection or an indirect connection through an intermediate medium; as a connection within two elements or an interaction between two elements, unless otherwise expressly limited. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.

[0064] Furthermore, the term "above" as used herein with respect to components, elements, or material layers formed or located "above" a surface may be used to indicate that the component, element, or material layer is "indirectly" positioned (e.g., placed, formed, deposited, etc.) on the surface such that one or more additional components, elements, or layers are arranged between the surface and the component, element, or material layer. However, the term "above" as used with respect to components, elements, or material layers formed or located "above" a surface may also optionally have a specific meaning: that the component, element, or material layer is "directly" positioned (e.g., placed, formed, deposited, etc.) on the surface, for example, in direct contact with the surface.

[0065] It should be understood that spatial relative terms, such as “above,” “upper,” “below,” and “lower,” are used herein to describe the relationship between one element and another shown in the figures. In addition to the orientation depicted in the figures, these spatial relative terms are also intended to encompass different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as “above” or “upper” relative to another element would be “below” or “lower” relative to that other element. Thus, depending on the spatial orientation of the device, the term “above” encompasses both above and below orientations. Devices may have other orientations (e.g., rotated 90 degrees or in other orientations), and the spatial relative terms used herein should be interpreted accordingly.

[0066] Although terms such as “first,” “second,” and “third” may be used herein to describe various components, parts, regions, layers, or sections, these components, parts, regions, layers, or sections are not limited to these terms. Rather, these terms are used only to distinguish one component, part, region, layer, or section from another. Therefore, without departing from the teachings of the examples described herein, a first component, part, region, layer, or section mentioned in the examples may also be referred to as a second component, part, region, layer, or section. Furthermore, the terms “first” and “second” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as “first” or “second” may explicitly or implicitly include at least one of that feature.

[0067] It is further understood that the terms "first," "second," etc., are used to describe various types of information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another, and do not indicate a specific order or degree of importance. In fact, the expressions "first," "second," etc., are completely interchangeable. For example, without departing from the scope of this disclosure, first information can also be referred to as second information, and similarly, second information can also be referred to as first information.

[0068] In this description, "multiple" means at least two, referring to two or more, such as two, three, etc., unless otherwise explicitly specified. Other quantifiers are similar. The singular forms "a," "the," and "the" are also intended to include the plural forms unless the context clearly indicates otherwise. Furthermore, unless otherwise specified or clearly indicated from the context, the articles "a" and "an" as used in this application and the appended claims are generally understood to mean "one or more."

[0069] It should be understood that, unless otherwise specifically indicated, features of various embodiments of this disclosure described herein can be combined with each other. As used herein, the term "and / or" includes any one of the related listed items and any combination of two or more; "and / or" describes the association relationship between related objects, indicating that three relationships may exist, for example, A and / or B can represent: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. Similarly, "at least one of..." includes any one of the related listed items and any combination of two or more.

[0070] Furthermore, the term "exemplary" is used herein to indicate that it serves as an example, instance, or illustration. Any aspect or design described herein as "exemplary" is not necessarily to be construed as advantageous compared to other aspects or designs.
