Description

Foldable electronic devices

[0001] This application claims priority to Chinese patent application No. 202410928197.9, filed on July 10, 2024, entitled "Foldable Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic device technology, and in particular to a foldable electronic device. Background Technology

[0003] In recent years, electronic devices have been updated at an increasingly rapid pace. Foldable electronic devices, which combine a larger display area with better portability, are becoming increasingly popular among users.

[0004] Foldable electronic devices typically include a display screen, a hinge, and two housings. The two housings are mounted on either side of the hinge via swing arms and can rotate relative to the hinge. The display screen is mounted on the two housings and the hinge. When the two housings are rotated so that they are facing each other, the display screen is folded, making the foldable electronic device easy to carry. When the two housings are rotated so that they are on the same plane, the display screen is unfolded, providing a larger display area.

[0005] In related technologies, the central area of ​​the display screen is prone to relatively uneven areas, which affects the display effect. Summary of the Invention

[0006] This application provides a foldable electronic device that can provide a flatter support for the display screen, thereby improving the display effect.

[0007] The technical solution is as follows:

[0008] This application provides a foldable electronic device, including a first housing, a second housing, a hinge mechanism, a display screen, and a support plate, wherein...

[0009] The first housing and the second housing are respectively connected to both sides of the rotating shaft mechanism in a first direction and can rotate relative to the rotating shaft mechanism. The first direction is the width direction of the rotating shaft mechanism.

[0010] The support plate covers at least a portion of the first housing, a portion of the rotating shaft mechanism, and a portion of the second housing. The support plate is fixedly connected to the first housing and slidably connected to the second housing.

[0011] The display screen is located on the side of the support plate away from the rotating shaft mechanism, and the display screen at least covers the support plate.

[0012] In the foldable electronic device provided in this application embodiment, since the support sheet covers a portion of the first housing, a portion of the hinge mechanism, and a portion of the second housing, the support sheet conceals the gap between the first housing and the hinge mechanism, as well as the gap between the second housing and the hinge mechanism. Furthermore, because the support sheet is made of sheet material, its surface has relatively high flatness. The support sheet supports the display screen, thereby providing a relatively flat support surface for the display screen, reducing screen deformation and improving the display effect.

[0013] In some implementations, the foldable electronic device also includes a fixed structure that is fixedly connected to the second housing, and a support plate having a sliding portion that is slidably mounted on the fixed structure.

[0014] In this configuration, the second housing is mounted on a fixed structure and slidably installed with the support plate, thus eliminating the need to modify the structure of the second housing itself and reducing manufacturing costs.

[0015] In some implementations, the fixed structure has a guide section, a sliding section, and a guide section, one of which is a slider and the other is a groove, with the slider slidably installed in the groove.

[0016] In this configuration, the fixed structure provides better guidance for the support plate, improving the stability of the support plate during its movement relative to the second housing.

[0017] In some implementations, the guide is a groove that passes through the fixed structure along a first direction.

[0018] This configuration facilitates the production and processing of the sliding groove on the fixed structure, thereby improving production efficiency.

[0019] In some implementations, the guide portion has a first opening located on the side of the guide portion facing the second housing. The first opening communicates with a slide groove and is used to allow the guide portion to enter the slide groove. The second housing covers the first opening.

[0020] In this configuration, the guide part can enter the slide groove through the first opening, which facilitates the sliding assembly of the guide part with the fixed structure.

[0021] In some implementations, a limiting part is provided on at least one side of the sliding part in the second direction, and the second direction is set at an angle to the first direction; the limiting part is located outside the slide groove and is used to limit the movement range of the sliding part in the first direction.

[0022] In this configuration, the limiting part limits the sliding part in the first direction.

[0023] In some implementations, the limiting part is located at the end of the sliding part away from the first housing.

[0024] In this configuration, the limiting part can prevent the sliding part from dislodging from the groove to a certain extent.

[0025] In some implementations, there are multiple sliding parts, which are spaced apart in a second direction, forming an angle with the first direction. The fixing structure includes multiple guide parts, and the multiple sliding parts are slidably connected to the multiple guide parts in a one-to-one correspondence.

[0026] In this configuration, there is a gap between adjacent guide sections, thereby reducing the weight of the support plate.

[0027] In some implementations, the length of the support plate is greater than half the length of the shaft mechanism along its longitudinal direction.

[0028] In this configuration, the support plate provides a larger support area for the display screen, resulting in better support.

[0029] In some implementations, the support sheet is connected to the first housing via a colloid.

[0030] In this configuration, the connection process between the support plate and the first housing is simple and convenient.

[0031] In some implementations, the side of the support sheet closest to the first housing has an adhesive-containing area, and the adhesive is at least partially located in the adhesive-containing area.

[0032] In this configuration, the support sheet can accommodate more adhesive through the adhesive-containing area, thereby improving the connection strength between the support sheet and the first housing.

[0033] In some implementations, the adhesive region extends through the support sheet in the thickness direction.

[0034] In this configuration, the support plate is relatively lighter.

[0035] In some implementations, the first housing is provided with a boss, at least a portion of which is located within the adhesive-containing area, and the adhesive is located between the inner wall of the adhesive-containing area and the boss.

[0036] In this configuration, the boss acts as a limit for the support piece, thereby providing initial positioning for the support piece during the connection process between the support piece and the first housing, facilitating the connection operation between the support piece and the first housing.

[0037] In some implementations, the support plate is welded and fixed to the first housing.

[0038] In this configuration, the connection process between the support plate and the first housing is simple, convenient, and has high connection strength.

[0039] In some implementations, a recessed structure is provided on the side of the first housing facing the support piece, and one end of the support piece in the first direction is located within the recessed structure.

[0040] In this configuration, the structure of the support plate and the first housing is more compact and occupies relatively less space.

[0041] In some implementations, the support sheet is a sheet made of thermally conductive material.

[0042] In this configuration, the support plate not only supports the display screen, but also conducts heat between the first and second housings, improving the heat dissipation effect of the first and second housings.

[0043] In some implementations, the foldable electronic device also includes a heat source device mounted on a first or second housing, with a support plate in contact with the heat source device.

[0044] In this configuration, the support plate can improve the heat dissipation effect on the heat source device. Attached Figure Description

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0064] It should be understood that "multiple" as mentioned in this application refers to two or more. In the description of this application, unless otherwise stated, " / " indicates "or," for example, A / B can mean A or B; "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist, for example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, to facilitate a clear description of the technical solutions of this application, the terms "first," "second," etc., are used to distinguish identical or similar items with essentially the same function and effect. Those skilled in the art will understand that the terms "first," "second," etc., do not limit the quantity or execution order, and that "first," "second," etc., do not necessarily imply differences.

[0065] In related technologies, foldable electronic devices include two housings, a hinge, and a display screen. The two housings are rotatably mounted on both sides of the hinge, and the display screen is laid on one side of the two housings and the hinge. The two sides of the display screen are supported by the two housings, and the foldable area of ​​the display screen is supported by the hinge. In these technologies, a certain gap exists between the housings and the hinge. This gap cannot support the display screen, causing the area of ​​the display screen opposite to the gap to easily sag towards the gap, thus degrading the surface flatness of the display screen and affecting its display effect. There is a height difference between the surface of the hinge facing the display screen and the surface of the housing facing the display screen; typically, the hinge is lower than the housing. This causes a depression to appear in the area between the two housings opposite the hinge when the foldable electronic device is in a flattened state, making the area of ​​the display screen opposite to the gap easily sag towards the gap, thus degrading the surface flatness of the display screen and affecting its display effect. It is worth noting that when the flatness of the display screen is relatively poor, not only will creases appear on the display screen, but the uneven areas on the display screen will also have multiple shadows and areas with strong reflections, thus affecting the display effect. Furthermore, the hinge contains a relatively large number of structures with varying heights, resulting in a relatively poor flatness of the hinge's surface facing the display screen, thus affecting the display's performance. Additionally, the hinge connects to the housing via a swing arm; if the foldable display device is dropped and impacted, the swing arm may bulge out relative to other structures within the hinge and strike the display screen, further compromising the reliability of the foldable display device.

[0066] The foldable electronic device provided in the embodiments of this application will be explained in detail below. In the various figures of this application, the leads with hollow arrows point to the surface of the device, the leads with dots point to a certain spatial area such as holes, slots, and cavities, and the leads with solid arrows point to the device itself.

[0067] Foldable electronic devices include, but are not limited to, cellphones, notebook computers, tablet computers, laptop computers, personal digital assistants, wearable devices, and mobile devices. In this embodiment, a cellphone is used as an example of a foldable electronic device for illustration.

[0068] Figure 1 shows the foldable electronic device in a folded state, Figure 2 shows the foldable electronic device in a semi-open state, and Figure 3 shows the foldable electronic device in an open state. The open angle α of the foldable electronic device in Figure 2 is 90 degrees, and the open angle β of the foldable electronic device in Figure 3 is 180 degrees.

[0069] It should be noted that the angles illustrated in the embodiments of this application are allowed to have slight deviations. For example, the unfolding angle α of the foldable electronic device 1 shown in Figure 2 being 90 degrees means that α can be 90 degrees, or approximately 90 degrees, such as 80 degrees, 85 degrees, 95 degrees, or 100 degrees. The unfolding angle β of the foldable electronic device 1 shown in Figure 3 being 180 degrees means that β can be 180 degrees, or approximately 180 degrees, such as 170 degrees, 175 degrees, 185 degrees, and 190 degrees. The angles illustrated in the following examples can be understood in the same way.

[0070] The foldable electronic device 1 shown in this embodiment is an electronic device that can be folded once. In some other embodiments, the foldable electronic device 1 can also be an electronic device that can be folded multiple times (more than twice). In this case, the foldable electronic device 1 may include multiple parts, with two adjacent parts folded relatively close together until the foldable electronic device 1 is in a folded state, and two adjacent parts unfolded relatively far apart until the foldable electronic device 1 is in an unfolded state.

[0071] For ease of description, the length, width, and thickness directions mentioned in this embodiment refer to the length, width, and thickness directions of the foldable electronic device 1. The width direction of the foldable electronic device 1 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular. It should be noted that the dimension in the width direction is not necessarily larger than the dimension in the length direction. It is also worth noting that the limiting terms for parallel and perpendicular positional relationships mentioned in this embodiment are relative to the current technological level, not absolute and strict mathematical definitions. Slight deviations are allowed; approximations of parallelism and perpendicularity are acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees. In this embodiment, the foldable electronic device 1 is described using directional terms such as "top," "bottom," "left," "right," "front," and "rear." The orientation is mainly based on the orientation of the foldable electronic device 1 shown in Figure 3. The positive Y-axis direction is "top," the negative Y-axis direction is "bottom," the positive X-axis direction is "left," the negative X-axis direction is "right," the positive Z-axis direction is "front," and the negative Z-axis direction is "rear."

[0072] Please refer to Figure 4, which is an exploded structural diagram of the foldable electronic device 1 shown in Figure 3. The foldable electronic device 1 includes a first housing 100, a second housing 200, a pivot mechanism 300, a display screen 700, and a support plate 400. The pivot mechanism 300 connects the first housing 100 and the second housing 200. Specifically, the first housing 100 and the second housing 200 are respectively mounted on both sides of the pivot mechanism 300 in a first direction, which is the width direction of the pivot mechanism 300. For example, the first housing 100 and the second housing 200 are respectively mounted on the left and right sides of the pivot mechanism 300. The first housing 100 and the second housing 200 rotate relative to each other via the pivot mechanism 300. The rotation directions of the first housing 100 and the second housing 200 are opposite.

[0073] The support plate 400 may be made of metal or composite material; exemplarily, the support plate 400 is a steel sheet. The support plate 400 is made of a sheet material capable of deformation and recovery to a certain extent, and can change between a folded state and a fully unfolded state. The support plate 400 is located on one side of the first housing 100, the second housing 200, and the pivot mechanism 300; specifically, the support plate 400 is located on the front side of the first housing 100, the second housing 200, and the pivot mechanism 300. The area of ​​the support plate 400 opposite the pivot mechanism 300 can be bent.

[0074] The display screen 700 is located on the side of the support plate 400 opposite to the hinge mechanism 300 in the thickness direction of the foldable electronic device 1, and the display screen 700 at least covers the support plate 400. When the support plate 400 is located in front of the hinge mechanism 300, the display screen 700 is located in front of the support plate 400, and the hinge mechanism 300 is located behind the support plate 400.

[0075] The display screen 700 includes a first portion 710, a second portion 720, and a foldable portion 730. The foldable portion 730 is located between the first portion 710 and the second portion 720, and the foldable portion 730 can be bent along the Y-axis direction. The first portion 710, the second portion 720, and the foldable portion 730 together constitute the display screen 700. In this embodiment, the display screen is a flexible display screen, such as an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MOLED) display screen, or a quantum dot light-emitting diode (QLED) display screen.

[0076] The foldable electronic device 1 folds by bringing the first housing 100 and the second housing 200 closer together. When the foldable electronic device 1 is in the folded state, the foldable portion 730 of the display screen 700 bends, with the first portion 710 and the second portion 720 positioned opposite each other. In the support piece 400, the area opposite to the pivot mechanism 300 bends, and the areas opposite to the first housing 100 and the second housing 200 are positioned opposite each other. At this time, both the display screen 700 and the support piece 400 are positioned between the first housing 100 and the second housing 200, which greatly reduces the probability of damage to the display screen 700 and effectively protects it.

[0077] Please refer to Figures 2 and 4. The first housing 100 and the second housing 200 rotate relative to each other via a pivot mechanism 300. The relative movement of the first housing 100 and the second housing 200 causes the display screen 700 to unfold, allowing the foldable electronic device 1 to unfold to a semi-unfolded state. When the foldable electronic device 1 is in the semi-unfolded state, the first housing 100 and the second housing 200 unfold to an angle α, the first part 710 and the second part 720 unfold relative to each other, and the foldable part 730 unfolds. At this time, the angle between the first part 710 and the second part 720 is α. During the process of the foldable electronic device 1 unfolding from a folded state to a semi-unfolded state, one end of the support piece 400 is fixedly connected to the first housing 100, and the other end moves relative to the second housing 200 along the width direction of the second housing 200, with the folded support piece 400 unfolding to an angle α.

[0078] Please refer to Figures 2 to 4. The first housing 100 and the second housing 200 rotate relative to each other via a pivot mechanism 300. The first housing 100 and the second housing 200 can have the same structure and can be mirror-symmetrically arranged with respect to the pivot mechanism 300. The support piece 400 is further unfolded as the first housing 100 and the second housing 200 move away from each other. During the unfolding process, one end of the support piece 400 connected to the first housing 100 is fixed to the first housing 100, while the other end of the support piece 400 opposite to the second housing 200 moves relative to the second housing 200. This further unfolds the display screen 700 until the foldable electronic device 1 is flattened. When the foldable electronic device 1 is flattened, the angle between the first housing 100 and the second housing 200 is β. After the support piece 400 is flattened, the angle is β. The foldable portion 730 unfolds, with the first portion 710 and the second portion 720 unfolding relative to each other. At this point, the included angles between the first part 710, the second part 720, and the foldable part 730 are all β. The display screen 700 has a large display area, realizing a large-screen display for the foldable electronic device 1 and improving the user experience. It should be noted that both included angles α and β are the included angles between the first housing 100 and the second housing 200. These are used only to distinguish the different angles between the first housing 100 and the second housing 200 in different states of the foldable electronic device 1. Specifically, included angle α refers to the angle between the first housing 100 and the second housing 200 when the foldable electronic device 1 is in its semi-open state; included angle β refers to the angle between the first housing 100 and the second housing 200 when the foldable electronic device 1 is in its open state.

[0079] It should be understood that the foldable electronic device 1 shown in this application embodiment is folded inward, and the display screen 700 of the foldable electronic device 1 in the folded state is located inside the pivot mechanism 300. In some other embodiments, the foldable electronic device 1 can also be folded outward. In this case, the display screen 700 of the foldable electronic device 1 in the folded state is located outside the support piece 400, and the support piece 400 is located outside the pivot mechanism 300.

[0080] The display screen 700 is laid on one side of the first housing 100, the second housing 200 and the pivot mechanism 300, and the display screen 700 is located on the side of the support plate 400 away from the pivot mechanism 300. The projection of the display screen 700 in the thickness direction completely covers the support plate 400. That is, the projection area of ​​the display screen 700 in the thickness direction can be greater than or equal to the projection area of ​​the support plate 400 in the thickness direction.

[0081] The area in the first housing 100 that supports the support plate 400 is designated as the first support surface, the area in the second housing 200 that supports the support plate is designated as the second support surface, and the area in the rotating shaft mechanism 300 that supports the support plate 400 is designated as the third support surface. The first support surface is at least a portion of the front side surface of the first housing 100, the second support surface is at least a portion of the front side surface of the second housing 200, and the third support surface is at least a portion of the front side surface of the rotating shaft mechanism 300.

[0082] When the projected area of ​​the display screen 700 in the thickness direction is equal to the projected area of ​​the support plate 400 in the thickness direction, the support plate 400 completely covers the first support surface, the second support surface and the third support surface. The first housing 100, the second housing 200 and the rotating shaft mechanism 300 respectively support the display screen 700 through the support plate.

[0083] When the projected area of ​​the display screen 700 in the thickness direction is larger than the projected area of ​​the support plate 400 in the thickness direction, the portion of the support plate 400 covering the first support surface means that the portion of the first housing 100 covered by the support plate 400 supports the display screen through the support plate 400, while the remaining portion of the first housing 100 supports the display screen through the first support surface not covered by the support plate 400. The portion of the support plate 400 covering the second support surface means that the portion of the second housing 200 covered by the support plate 400 supports the display screen through the support plate 400, while the remaining portion of the second housing 200 supports the display screen through the second support surface not covered by the support plate 400. The portion of the support plate 400 covering the third support surface means that the portion of the pivot mechanism 300 covered by the support plate 400 supports the display screen through the support plate 400, while the remaining portion of the pivot mechanism 300 supports the display screen through the third support surface not covered by the support plate 400.

[0084] When the support plate 400 covers a portion of the first housing 100, a portion of the pivot mechanism 300, and a portion of the second housing 200, exemplarily, as shown in FIG5, when the foldable electronic device 1 is in its fully unfolded state, the length of the front side of the foldable electronic device 1 is L1, the width is W1, the length of the support plate 400 is L2, and the width is W2, where L2 ≤ L1 and W2 ≤ W1. In FIG5, L2 < L1, and W2 < W1.

[0085] As shown in Figures 5 to 7, the support plate 400 is a complete sheet structure. Since the support plate 400 covers the first housing 100, the second housing 200, and the pivot mechanism 300, the left and right sides of the support plate 400 are located in front of the first housing 100 and the second housing 200, respectively. The width of the support plate 400 is at least greater than the width of the pivot mechanism 300. The support plate 400 covers at least a portion of the first gap 611 between the first housing 100 and the pivot mechanism 300, and at least a portion of the second gap 612 between the second housing 200 and the pivot mechanism 300. This reduces the area of ​​the display screen 700 relative to the gap after the display screen 700 is laid on the front side of the support plate 400, thereby improving the flatness of the display screen 700. Furthermore, after the foldable display device is dropped and impacted, the support plate 400 can disperse and transfer the impact force transmitted by the pivot mechanism 300 toward the display screen 700 to the first housing 100 and the second housing 200, thereby reducing the impact force on the display screen 700, improving the protection effect on the display screen 700, and improving the stability of the foldable display device after being impacted.

[0086] In some embodiments, as shown in Figures 5, 6, and 7, both the first housing 100 and the second housing 200 are mid-frames. The pivot mechanism 300 includes a base, a swing arm, and a door panel. The swing arm includes a first swing arm and a second swing arm, and the door panel includes a first door panel 310 and a second door panel 320. The first swing arm and the second swing arm are rotatably mounted on the base, respectively. The first swing arm is connected to the first housing 100 through the first door panel 310, and the second swing arm is connected to the second housing 200 through the second door panel 320. The first housing 100 rotates relative to the base via the first swing arm, and the second housing 200 rotates relative to the base via the second swing arm. A support plate is disposed on the front side of the first housing 100, the second housing 200, and the pivot mechanism 300. The width of the support plate 400 is greater than the width of the pivot mechanism 300. The width of the pivot mechanism 300 is such that when the foldable electronic device 1 is in its fully unfolded state, there is a first gap 611 between the first door panel 310 and the first housing 100, and a second gap 612 between the second door panel 320 and the second housing 200. The maximum distance between the sides of the first door panel 310 and the second door panel 320 away from each other is in the width direction of the foldable electronic device 1, such that the support plate can at least cover the first gap 611 between the first door panel 310 and the first housing 100, and the second gap 612 between the second door panel 320 and the second housing 200, and the support plate covers the first swing arm and the second swing arm. In this configuration, even if there is an assembly error at any point between the first swing arm and the first door panel 310, between the first door panel 310 and the first housing 100, between the second swing arm and the second door panel 320, or between the second door panel 320 and the second housing 200, resulting in a height difference on the front side, the support plate covers at least part of both the first gap 611 and the second gap 612. This reduces the area with a height difference in the support surface that contacts the display screen 700, thereby improving the flatness of the support surface used to support the display screen 700 in the foldable electronic device 1, so as to reduce the creases of the display screen 700 caused by the height difference of the support surface.

[0087] As shown in Figure 5, in the width direction of the foldable electronic device 1, the width W2 of the support piece 400 is greater than the width W3 of the pivot mechanism 300, and the width of the support piece 400 is less than the width W1 of the foldable electronic device 1.

[0088] In some embodiments, along the length of the foldable electronic device 1, the length L2 of the support piece 400 is less than the length L3 of the hinge mechanism 300, and the length L2 of the support piece 400 is greater than or equal to half the length L3 of the hinge mechanism 300. The length L3 of the hinge mechanism 300 is less than or equal to the length L1 of the foldable electronic device 1. Exemplarily, the length L2 of the support piece 400 may be 50%, 60%, 70%, 75%, 80%, or 90% of the length L3 of the hinge mechanism 300. In this configuration, since the length L2 of the support piece 400 is less than the length L3 of the hinge mechanism 300, the support piece 400 can be completely covered by the display screen 700. Since the length L2 of the support piece 400 is greater than or equal to half the length L3 of the hinge mechanism 300, the support piece 400 can cover a larger area of ​​the first gap 611 and a larger area of ​​the second gap 612.

[0089] In some implementations, a mating structure (not shown in the figure) is provided on the second housing 200, and the support piece 400 is slidably mounted on the mating structure. The mating structure can guide and limit the support piece 400. For example, the mating structure can be a slide rail, and a slider is provided on the support piece 400, which is mounted on the slide rail and can slide relative to the slide rail. In another example, the mating structure is a groove extending along a first direction. Two grooves can be provided relative to the support piece 400, with the top edge of the support piece 400 extending into one groove and the bottom edge of the support piece 400 extending into the other groove. The support piece 400 can move relative to the two grooves in the first direction.

[0090] As shown in Figures 8 and 9, in some implementations, the foldable electronic device 1 further includes a fixing structure 500, which is fixedly connected to the second housing 200. The support plate 400 has a sliding portion 410, which is slidably mounted on the fixing structure 500. The fixing structure 500 and the second housing 200 are separate structures, manufactured independently during the production process, and then connected together. The fixing structure 500 and the second housing 200 can be fixedly connected by means of bonding, welding, snap-fitting, screwing, riveting, etc. A fixed connection means that the relative positions of the fixing structure 500 and the second housing 200 remain unchanged after connection. The fixed connection can be detachable or non-detachable. The sliding portion 410 is a part of the support plate 400 that faces the second housing 200.

[0091] In this configuration, the second housing 200 is mounted on the fixing structure 500 and slidably installed with the support plate 400. This eliminates the need to modify the structure of the second housing 200 itself, meaning that there is no need to redesign the structure of the second housing 200, reducing design costs. Furthermore, the second housing 200 can be produced using the original manufacturing equipment and processes, thereby reducing the cost of updating the production equipment or adding production processes for the second housing 200.

[0092] In some implementations, the fixing structure 500 has a guide portion, a sliding portion 410, and a guide portion, one of which is a slider and the other is a groove, with the slider slidably mounted within the groove. For example, the guide portion is a slider, the sliding portion 410 is a groove, the slider is mounted within the groove, and the fixing structure 500 with the groove is movable relative to the slider along a first direction. Alternatively, the guide portion is a groove, the sliding portion 410 is a slider, the slider is mounted within the groove, and the fixing structure 500 with the slider is movable relative to the groove along a first direction. In this configuration, the fixing structure 500 provides relatively better guidance for the support piece 400, improving the stability of the support piece 400 during movement relative to the second housing 200.

[0093] For example, as shown in FIG10, the support plate 400 is a generally rectangular sheet. In a first direction, the support plate 400 is sequentially provided with a first region 421, a second region 422, and a third region 423. The first region 421 is used for fixed connection with the first housing 100, the third region 423 is used for fixed structure 500 to slide, and the second region 422 is located between the first region 421 and the third region 423, and can be bent and return to its original shape. The third region 423 is the slider in the sliding part 410 used to install into the sliding groove.

[0094] In some implementations, the fixed structure 500 can be a steel sheet. In the length direction of the rotating shaft mechanism 300, the length of the fixed structure 500 is greater than the length of the support sheet 400. The fixed structure 500 is fixedly connected to the second housing 200 at both ends in the length direction.

[0095] In some implementations, the guide is a groove 510, which extends along a first direction, and the width of the groove 510 may be less than or equal to the width of the fixed structure 500.

[0096] When the width of the slide groove 510 is less than the width of the fixed structure 500, the slide groove 510 has an inlet and a limiting wall, which is the inner wall of the slide groove 510 opposite to the inlet. The sliding part 410 extends into the slide groove 510 through the inlet. During the folding process of the foldable electronic device 1, the angle between the first housing 100 and the second housing 200 gradually decreases, and the sliding part 410 moves along the first direction toward the limiting wall. During the unfolding process of the foldable electronic device 1, the angle between the first housing 100 and the second housing 200 gradually increases, and the sliding part 410 moves along the first direction away from the limiting wall. The inner wall of the slide groove 510 in the thickness direction of the foldable electronic device 1 limits the sliding part 410 in the thickness direction of the foldable electronic device 1, and the limiting wall limits the sliding part 410 to the farthest position it moves toward the limiting wall, thereby limiting the range of movement of the sliding part 410.

[0097] When the width of the slide groove 510 is equal to the width of the fixed structure 500, the slide groove 510 penetrates the fixed structure 500 along the first direction. The slide groove 510 has an inlet and an outlet. The inlet is located on the side of the slide groove 510 closer to the first housing 100 in the first direction, and the outlet is located on the side of the slide groove 510 away from the first housing 100 in the first direction. The inlet and outlet are arranged opposite to each other in the first direction. The sliding part 410 extends into the slide groove 510 through the inlet, and the end of the sliding part 410 away from the first housing 100 extends through the outlet to the side of the slide groove 510 away from the first housing 100. During the folding process of the foldable electronic device 1, the angle between the first housing 100 and the second housing 200 gradually decreases, the sliding part 410 moves in the first direction away from the first housing 100, and the length of the sliding part 410 extending through the outlet to the outside of the slide groove 510 increases. During the unfolding of the foldable electronic device 1, the angle between the first housing 100 and the second housing 200 gradually increases, and the sliding part 410 moves along the first direction toward the first housing 100, reducing the length of the sliding part 410 extending outward through the outlet to the outside of the slide groove 510. The inner wall of the slide groove 510 in the thickness direction of the foldable electronic device 1 limits the sliding part 410 in the thickness direction of the foldable electronic device 1. Since the slide groove 510 penetrates the fixing structure 500 along the first direction, the sliding part 410 can extend out of the slide groove 510. Therefore, even if the width of the slide groove 510 is less than the moving distance of the sliding part 410 in the first direction, the slide groove 510 can still limit the sliding part 410 throughout its movement. That is to say, a relatively narrow fixing structure 500 can be used to achieve the limiting and guiding effect on the sliding part 410. The relatively smaller width of the fixing structure 500 results in a smaller structural size, less space occupation, and lighter weight. Furthermore, since the slide groove 510 penetrates the fixed structure 500, the fitting accuracy requirement between the sliding part 410 and the slide groove 510 in the first direction is relatively lower, and it is less affected by manufacturing errors and assembly errors, thereby reducing manufacturing costs and facilitating the assembly of the fixed structure 500 and the support plate 400.

[0098] In some implementations, as shown in Figure 11, the inner cavity of the slide 510 is cubic in shape. The slide 510 has two sidewalls arranged opposite each other along the length direction of the foldable electronic device 1 and two sidewalls arranged opposite each other along the thickness direction of the foldable electronic device 1. The four sidewalls are connected to form a closed annular inner wall of the slide 510. In this configuration, the two sidewalls arranged opposite each other along the thickness direction of the foldable electronic device 1 in the slide 510 serve to limit the sliding part 410 in the front-back direction.

[0099] In some implementations, as shown in Figure 12, the guide portion has a first opening 511 located on the side of the guide portion facing the second housing 200. The first opening 511 communicates with the slide groove 510 and is used for the guide portion to enter the slide groove 510. The second housing 200 covers the first opening 511. In this configuration, the slide groove 510 is fastened to the second housing 200, with the front side wall of the second housing 200 serving as the rear inner wall of the slide groove 510. The slide groove 510 has a front inner wall in the thickness direction of the foldable electronic device 1. The front inner wall and the second housing 200 respectively limit the sliding portion 410 in the front and rear directions. During the assembly of the foldable electronic device 1, the sliding portion 410 of the support piece 400 can be first placed into the slide groove 510 through the first opening 511, so that the support piece 400 and the fixed structure 500 are relatively positioned. Then, the fixed structure 500 is fixedly connected to the second housing 200, so that the sliding portion 410 of the support piece 400 is slidably assembled in the slide groove 510. The first opening 511 facilitates the assembly of the support piece 400 and the fixed structure 500, and the first opening 511 allows the second housing 200 to provide a rear-side limiting effect on the support piece 400, thus eliminating the need for a rear inner wall of the slide groove 510, and further reducing the thickness of the fixed structure 500, thereby reducing the weight of the fixed structure 500.

[0100] When the slide 510 penetrates the guide fixing structure 500 along the first direction, the sliding part 410 is provided with a limiting part 440 in the second direction. The second direction is set at an angle to the first direction, and the limiting part 440 is used to limit the movement distance of the sliding part 410 in the first direction. The second direction is not parallel to the first direction. For example, the angle between the second direction and the first direction is greater than 0° and less than 180°. For example, the angle between the second direction and the first direction can be 30°, 45°, 90°, 120° or 150°, etc. In a specific example, the first direction is the width direction of the foldable electronic device 1, the second direction is the length direction of the foldable electronic device 1, and the first direction is perpendicular to the second direction. The sliding part 410 can be provided with limiting parts 440 on both sides in the second direction. The limiting parts 440 are located on the outside of the slide 510, and at least a portion of the limiting part 440 is opposite to one of the two outer surfaces of the fixing structure 500 that are spaced apart in the first direction. For example, when the limiting part 440 is located between the fixing structure 500 and the first housing 100, at least a portion of the limiting part 440 is disposed opposite to the side of the fixing part close to the first housing 100 in the first direction. When the sliding part 410 moves away from the first housing 100 (the foldable electronic device 1 folds), the distance between the limiting part 440 and the fixing structure 500 gradually decreases. When the limiting part 440 comes into contact with the fixing structure 500, the sliding part 410 stops moving away from the first housing 100. That is, the limiting part 440 plays a limiting role for the sliding part 410 in the first direction. When the limiting part 440 is located on the side of the fixed structure 500 away from the first housing 100, at least a portion of the limiting part 440 is disposed opposite to the side of the fixed part away from the first housing 100 in the first direction. When the sliding part 410 moves toward the first housing 100 (the foldable electronic device 1 unfolds), the distance between the limiting part 440 and the fixed structure 500 gradually decreases. When the limiting part 440 comes into contact with the fixed structure 500, the sliding part 410 stops moving toward the first housing 100. That is, the limiting part 440 plays a limiting role for the sliding part 410 in the first direction.

[0101] The sliding portion 410 has two opposing sides in the second direction. The limiting portion 440 may be provided on only one side, or the limiting portion 440 may be provided on both opposing sides of the sliding portion 410 in the second direction.

[0102] The limiting portion 440 is located on the outer side of the fixing structure 500 in the first direction. At least one of the sides of the fixing structure 500 near the first housing 100 and away from the first housing 100 may be provided with the limiting portion 440. Exemplarily, the limiting portion 440 may be provided only on the side of the fixing structure 500 near the first housing 100, or only on the side of the fixing structure 500 away from the first housing 100. Alternatively, at least two limiting portions 440 may be provided on the sliding portion 410, with at least one limiting portion 440 located on the side of the fixing structure 500 away from the first housing 100 and at least one limiting portion 440 located on the side of the fixing structure 500 near the first housing 100.

[0103] In some implementations, the limiting part 440 is disposed at the end of the sliding part 410 and located at the end of the sliding part 410 away from the first housing 100. The limiting part 440 is located on the side of the fixing structure 500 away from the first housing 100. The limiting part 440 and the sliding part 410 can be an integral structure. The support sheet 400 can be manufactured by producing a sheet material, and the sliding part 410 and the limiting part 440 can be formed by cutting one end of the sheet material.

[0104] The number of sliding parts 410 can be one or more.

[0105] As shown in Figures 8 and 9, when there is only one sliding part 410, a portion of the end of the support piece 400 located on the front side of the second housing 200 can be used as the sliding part 410, without further processing, resulting in high production efficiency.

[0106] As shown in Figures 13 and 14, when there are multiple sliding portions 410, the multiple sliding portions 410 are spaced apart in the second direction. The fixing structure 500 includes multiple guide portions, and the multiple sliding portions 410 are slidably connected to the multiple guide portions one-to-one. Multiple sliding portions 410 can be formed by cutting on a sheet. In this arrangement, there are gaps between adjacent guide portions, thereby reducing the weight of the support sheet 400.

[0107] In some implementations, the support piece 400 is welded to the first housing 100. For example, the support piece 400 and the first housing 100 are connected by spot welding. In this configuration, the connection process between the support piece 400 and the first housing 100 is simple, convenient, and the connection stability is relatively strong.

[0108] In some implementations, the support sheet 400 is connected to the first housing 100 via an adhesive. The adhesive can be tape, adhesive paper, liquid adhesive, etc. For example, the adhesive is double-sided tape, which is applied to the area of ​​the support sheet 400 facing the first housing 100, bringing the support sheet 400 into contact with the first housing 100. This allows the double-sided tape to adhere to the first housing 100, thus connecting the support sheet 400 to the first housing 100. In another example, liquid adhesive is applied to the area of ​​the support sheet 400 facing the housing. The support sheet 400 is then brought into contact with the first housing 100, and after curing, the adhesive forms a bond between the support sheet 400 and the first housing 100, connecting them. The process of connecting the support sheet 400 and the first housing 100 via adhesive is simple, convenient, and low-cost.

[0109] As shown in Figures 15 and 16, in some implementations, the support sheet 400 has an adhesive-containing area 430 on the side near the first housing 100, and the adhesive is at least partially located in the adhesive-containing area 430. The adhesive-containing area 430 can be a hole structure, which can be a through hole or a blind hole. The hole structure allows the support sheet 400 to accommodate more adhesive, increasing the thickness of the adhesive between the support sheet 400 and the first housing 100, thereby improving the connection strength between the support sheet 400 and the first housing 100. By providing the adhesive-containing area 430 on the support sheet 400, the range of adhesive can be limited. When the adhesive is a liquid, the inner wall of the adhesive-containing area 430 limits the flow range of the liquid, thereby reducing the amount of liquid overflow to a certain extent.

[0110] As shown in Figures 15 and 16, in some implementations, the adhesive-containing area 430 penetrates the support sheet 400 along its thickness direction. In this configuration, the adhesive-containing area 430 has a hole structure, specifically a through hole. Since the thickness of the support sheet 400 is relatively small, making the adhesive-containing area 430 a through hole reduces the processing difficulty of the adhesive-containing area 430. Furthermore, the fact that the adhesive-containing area 430 penetrates the support sheet 400 also reduces the weight of the support sheet 400.

[0111] For example, as shown in FIG16, there are multiple adhesive regions 430, and the multiple adhesive regions 430 are spaced apart in the first direction.

[0112] As shown in Figure 17, in some implementations, the first housing 100 is provided with a boss 110, at least a portion of which is located within the adhesive-containing area 430, and the adhesive is located between the inner wall of the adhesive-containing area 430 and the boss 110. The boss 110 is a structure in the first housing 100 that protrudes forward along the thickness direction of the first housing 100. The boss 110 and the first housing 100 can be an integral structure.

[0113] When the adhesive-containing area 430 does not penetrate the support piece 400, there is adhesive between the front side of the boss 110 and the inner wall of the adhesive-containing area 430, and between the circumferential side of the boss 110 and the inner wall of the adhesive-containing area 430; when the adhesive-containing area 430 penetrates the support piece 400, there is adhesive between the circumferential side of the boss 110 and the inner wall of the adhesive-containing area 430.

[0114] In some examples, the front side of the boss 110 is located within the adhesive-receiving area 430, or, where the adhesive-receiving area 430 extends through the support piece 400, the front side of the boss 110 may be flush with the front side of the support piece 400. In this configuration, the boss 110 does not protrude beyond the front side of the support piece 400.

[0115] In this configuration, the boss 110 serves to limit the support piece 400, thereby providing initial positioning for the support piece 400 during the connection process between the support piece 400 and the first housing 100, facilitating the connection operation between the support piece 400 and the first housing 100.

[0116] In some implementations, as shown in Figure 7, a recessed structure 120 is provided on the side of the first housing 100 facing the support piece 400, and one end of the support piece 400 in a first direction is located within the recessed structure 120. There is a height difference between the front side of the recessed structure 120 and the front sides of other areas of the first housing 100; that is, the recessed structure 120 is formed by recessing rearward from the front side of the first housing 100. The recessed structure 120 can be formed by cutting or stamping. The recessed structure 120 provides a receiving space for the support piece 400, making the height difference between the front side of the support piece 400 and the front sides of other areas of the first housing 100 relatively smaller. The front side of the support piece 400 can be flush with the front side of the area of ​​the first housing 100 adjacent to the support piece 400. In this configuration, the structure of the support piece 400 and the first housing 100 is more compact, occupying relatively less space in the thickness direction.

[0117] When the first housing 100 is provided with a boss 110 and the first housing 100 is provided with a recessed structure 120, the boss 110 is provided in the recessed structure 120.

[0118] In some implementations, the support sheet 400 is a sheet made of a thermally conductive material. For example, the support sheet 400 is a steel sheet. In this configuration, the support sheet 400 not only supports the display screen 700 but also conducts heat between the first housing 100 and the second housing 200, improving the heat dissipation of the first housing 100 and the second housing 200. Because the support sheet 400 conducts heat between the first housing 100 and the second housing 200, it also reduces the temperature difference between the first housing 100 and the second housing 200.

[0119] In some implementations, the foldable electronic device 1 also includes a heat source device mounted on the first housing 100 or the second housing 200, with the support plate 400 in contact with the heat source device. The heat source device is a device that generates heat during operation, such as a chip.

[0120] For example, a System on Chip (SOC) is mounted on the second housing 200, and a support plate 400 covers at least a portion of the SOC. Heat generated by the SOC can be partially dissipated through the second housing 200, and some heat generated by the SOC can be conducted through the support plate 400 to the first housing 100 and dissipated therefrom. In this configuration, the support plate 400 improves heat dissipation for heat-generating devices.

[0121] In one specific embodiment, the foldable electronic device 1 includes a first housing 100, a second housing 200, a pivot mechanism 300, a support plate 400, a fixing structure 500, and a display screen 700. Both the support plate 400 and the fixing structure 500 are generally rectangular steel sheets. The width of the support plate 400 is greater than the width of the fixing structure 500, and the length of the support plate 400 is less than the length of the fixing structure 500. A sliding groove 510 is provided through the fixing structure 500 along its width direction. One end of the support plate 400 is a sliding portion 410, which passes through the sliding groove 510. The rotating shaft mechanism 300 includes a base, a first swing arm, a second swing arm, a first door panel 310, and a second door panel 320. The first door panel 310 and the second door panel 320 are rotatably mounted on both sides of the base in the width direction. The first door panel 310 is rotatably connected to the base via the first swing arm, and the second door panel 320 is rotatably connected to the base via the second swing arm. The first door panel 310 is connected to the first housing 100, and the second door panel 320 is connected to the second housing 200. There is a first gap between the first door panel 310 and the first housing 100, and a second gap between the second door panel 320 and the second housing 200. One end of the support piece 400 is fixedly connected to the first housing 100. The edge of the support piece 400 away from the second housing 200 is located on the side of the first gap away from the second housing 200. The other end of the support piece 400 has a sliding portion 410, which passes through the groove 510 of the fixing structure 500. The fixing structure 500 is fixedly connected to the second housing 200 at both ends in the longitudinal direction. Since the two ends of the support piece 400 are located on the front side of the first housing 100 and the front side of the second housing 200, respectively, the support piece 400 covers the front side of at least a portion of the first gap and the front side of at least a portion of the second gap. The support plate 400 has at least three sliding portions 410 along its length. Of these sliding portions 410, one is located at the top, one at the bottom, and the remaining portions are located in the middle, between the aforementioned two portions 410. The top and bottom surfaces of the top sliding portion 410 are respectively provided with limiting portions 440; the top surface of the bottom sliding portion 410 is provided with a limiting portion 440; and the top and bottom surfaces of the ends of one or more sliding portions 410 in the middle are respectively provided with limiting portions 440. The support plate 400 is located between the display screen 700 and the pivot mechanism 300, providing a certain degree of support for the display screen 700.
