Description

An electronic device, a display assembly, a support assembly, and a reinforcing plate.

[0001] This application claims priority to Chinese Patent Application No. 202422243362.5, filed with the State Intellectual Property Office of China on September 12, 2024, entitled "An electronic device, display assembly, support assembly and reinforcing plate", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and in particular to an electronic device, a display assembly, a support assembly, and a reinforcing plate. Background Technology

[0003] With the rapid development of electronic device technology, users have an increasing demand for large-sized and portable electronic devices. Therefore, electronic devices with foldable displays have received widespread attention. Foldable screens can be unfolded when in use to provide a larger display area, and folded when not in use for easy portability.

[0004] Existing electronic devices typically have openings on both sides of the hinge for clearance or connection / fixing. These openings provide insufficient support for the display screen, potentially leading to issues such as bright spots and dark patches, thus failing to meet normal usage requirements. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device, a display assembly, a support assembly, and a reinforcing plate for improving the bright spots and black spots on the display screen.

[0006] A first aspect of this application provides an electronic device, comprising: a display screen, a support member, a reinforcing plate, and a hinge mechanism stacked together. The support member is disposed on a side opposite to the light-emitting surface of the display screen. The support member includes: a bendable portion, a first non-bendable portion, and a second non-bendable portion. When the display screen is in a flattened state, the bendable portion is located between the first non-bendable portion and the second non-bendable portion. The bendable portion is disposed opposite to the hinge mechanism.

[0007] The bendable portion includes a first region, which includes a first opening. The pivot mechanism includes a pivot panel, which includes a second region opposite to the first region. The second region includes a second opening. The first region and the second region are opposite to each other. The reinforcing plate includes a first portion. The first portion is stacked between the first region and the second region, and the first portion is used to cover the first opening and the second opening.

[0008] The first region of the support member has a first opening, resulting in poor support for the display screen. The second region of the hinge panel has a second opening, further reducing its support for both the first region and the display screen. The reinforcing plate of this application has a first portion positioned between the first and second regions, thereby providing support for both the first region of the support member and the display screen. Especially when the display screen is in a semi-folded state or under pressure, the support provided by the reinforcing plate improves the situation where insufficient support causes bright spots or black spots on the display screen in that area. Furthermore, the support provided by the first portion of the reinforcing plate also enhances the electronic device's resistance to compression and impact.

[0009] In one optional embodiment, the hinge mechanism includes two hinge panels. A first portion includes a first sub-region located on the hinge panel and a second sub-region located between the two hinge panels. The hinge mechanism also includes a hinge arc arm. The hinge arc arm is connected to the two hinge panels. At least a portion of the projection of the hinge arc arm onto the reinforcing plate is located in the second sub-region. The hinge arc arm and the two hinge panels can rotate in coordination, thereby causing the display screen to fold or unfold. The two first sub-regions on the two hinge panels can cover the first opening and the second opening. The second sub-region between the two hinge panels can cover at least a portion of the hinge arc arm. When the electronic device falls while suspended, this prevents the flexible part from impacting the hinge arc arm after the flexible part swings, thus avoiding black spots or bright spots on the display screen.

[0010] In one optional embodiment, along the bend line of the display screen, the hinge mechanism includes opposing first and second ends. The first and second ends are located at the edge of the electronic device. The first part includes a first sub-part and a second sub-part. The first sub-part is located near the first end, and the second sub-part is located near the second end. To avoid obstruction or for connection and fixation, multiple second openings are provided on both the portion of the hinge panel near the first end and the portion near the second end along the bend line of the display screen. The first sub-part, located near the first end, can block the second openings near the first end. The second sub-part, located near the second end, can block the second openings near the second end. The reinforcing plate can block multiple second openings, improving the support provided to the bendable part and the display screen.

[0011] In one optional embodiment, the first portion further includes a third sub-portion. The third sub-portion is disposed between the first sub-portion and the second sub-portion. The bendable portion includes a third region, and the third region includes a third opening. The third sub-portion is used to cover the third opening. By covering the third opening in the third region of the bendable portion with the third sub-portion, the supporting effect of the reinforcing plate on the bendable portion is further improved.

[0012] In one optional embodiment, the electronic device further includes: a first middle frame and a second middle frame. The first middle frame is disposed opposite to the first non-bending portion, and the first middle frame is capable of providing support for the first non-bending portion. The second middle frame is disposed opposite to the second non-bending portion. The first middle frame is capable of providing support for the first non-bending portion.

[0013] The reinforcing plate includes a second portion connected to the first portion. The second portion includes opposing first and second surfaces. The first surface of the second portion is connected to the first non-bending portion, and / or the second surface of the second portion is connected to the first middle frame. This is to fix the reinforcing plate so that it can be stably positioned between the support member and the pivot mechanism. When the display screen bends, the first portion bends, and the first portion can slide relative to the support member. This reduces the rebound force during bending and prevents the electronic device from failing to close due to excessive bending stress of the reinforcing plate.

[0014] In one optional embodiment, the reinforcing plate further includes a third portion. The third portion is connected to the first portion. When the display screen is in a flattened state, the third portion is located on the side of the first portion facing away from the second portion. The third portion of the reinforcing plate increases the friction between the reinforcing plate and the support member or the second frame, preventing sudden changes in force during bending and causing asynchronous bending deformation. The width of the third portion is smaller than the width of the first portion, thus facilitating the avoidance of the third portion from other components in the electronic device.

[0015] In one optional embodiment, the electronic device includes an adhesive layer. The adhesive layer is disposed on the surface of the bendable portion away from the display screen. A reinforcing plate includes clearance holes, in which the adhesive layer is disposed. The adhesive layer is cleared through the clearance holes on the reinforcing plate, ensuring that the bendable portions located on both sides of the reinforcing plate can be connected to the pivot mechanism via the adhesive layer. Furthermore, the clearance holes on the reinforcing plate reduce the stress during bending, thereby reducing the rebound force during bending and minimizing the impact of the reinforcing plate on the bending of the electronic device.

[0016] In one optional embodiment, the reinforcing plate includes a lubricating layer and a supporting layer stacked together. The lubricating layer is disposed on the surface of the supporting layer facing or away from the display screen and is connected to the supporting layer. The lubricating layer disposed on the surface of the supporting layer can reduce the friction between the reinforcing plate and the supporting member or rotating mechanism when bent, thereby facilitating the bending of the reinforcing plate. The lubricating layer can also improve the wear resistance of the reinforcing plate.

[0017] In one optional embodiment, the lubricating layer is made of Teflon or polyethylene terephthalate (PET). Both Teflon coatings and PET films have low coefficients of friction, ensuring minimal friction between the reinforcing plate and the support or rotating mechanism when the reinforcing plate slides. Teflon has excellent wear resistance and corrosion resistance, ensuring the service life of the lubricating layer.

[0018] In one optional embodiment, the thickness of the lubricating layer is 0.01mm-0.1mm. Exemplarily, the thickness of the lubricating layer can be 0.01mm, 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc. A lubricating layer thickness greater than or equal to 0.01mm can prevent damage to the lubricating layer when the electronic device is bent, thereby ensuring lubrication effectiveness. A lubricating layer thickness less than or equal to 0.1mm prevents an increase in the size of the electronic device due to an excessively thick lubricating layer.

[0019] In one optional embodiment, the support layer is made of a metallic material. For example, the support layer can be made of stainless steel, titanium alloy, etc. Metallic materials (such as stainless steel and titanium alloy) have high hardness, which can meet the support capacity required by the reinforcing plate.

[0020] In one optional embodiment, the thickness of the support layer is 0.01mm-0.1mm. For example, the thickness of the support layer can be 0.01mm, 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc. A support layer thickness greater than or equal to 0.01mm ensures the rigidity of the support layer, thereby guaranteeing the reinforcing plate's support capacity for the support component and the display screen. A support layer thickness less than or equal to 0.1mm avoids increasing the stress on the reinforcing plate during bending due to excessive support layer thickness, thus reducing the impact of the reinforcing plate on the bending of the electronic device. A support layer thickness less than or equal to 0.1mm prevents an increase in the size of the electronic device due to excessive support layer thickness.

[0021] A second aspect of this application provides a display screen assembly. The display screen assembly is used to connect with a hinge mechanism. The display screen assembly includes: a display screen, a support member, and a reinforcing plate stacked together. The support member is disposed on the side opposite to the light-emitting surface of the display screen. The support member includes: a bendable portion, a first non-bendable portion, and a second non-bendable portion. When the display screen is in a flattened state, the bendable portion is located between the first and second non-bendable portions, and the bendable portion is disposed opposite to the hinge mechanism. The bendable portion includes a first region. The first region includes a first opening. The hinge mechanism includes a hinge door plate. The hinge door plate includes a second region opposite to the first region. The second region includes a second opening. The first region and the second region are opposite to each other. The reinforcing plate includes: a first portion. The first portion is stacked between the first and second regions. The first portion is used to cover the first and second openings. The above-described display screen assembly has the same technical effects as the aforementioned electronic device, and will not be repeated here.

[0022] A third aspect of this application provides a support assembly. The support assembly is disposed between a display screen and a hinge mechanism. The support assembly includes: a support member and a reinforcing plate stacked together. The support member is disposed on the side opposite to the light-emitting surface of the display screen. The reinforcing plate is disposed between the support member and the hinge mechanism. The support member includes: a bendable portion, a first non-bendable portion, and a second non-bendable portion. When the display screen is in a flattened state, the bendable portion is located between the first and second non-bendable portions, and the bendable portion is disposed opposite to the hinge mechanism. The bendable portion includes a first region. The first region includes a first opening. The hinge mechanism includes a hinge door plate. The hinge door plate includes a second region opposite to the first region. The second region includes a second opening. The first region and the second region are opposite to each other. The reinforcing plate includes: a first portion. The first portion is stacked between the first and second regions. The first portion is used to cover the first and second openings. The above-described support assembly has the same technical effects as the aforementioned electronic device, and will not be repeated here.

[0023] A fourth aspect of this application provides a reinforcing plate. The reinforcing plate is used in an electronic device. The electronic device includes: a display screen, a support member, and a hinge mechanism stacked together. The support member is disposed on a side opposite to the light-emitting surface of the display screen. The support member includes: a bendable portion, a first non-bendable portion, and a second non-bendable portion. When the display screen is in a flattened state, the bendable portion is located between the first and second non-bendable portions. The bendable portion is disposed opposite to the hinge mechanism. The bendable portion includes a first region. The first region includes a first opening. The hinge mechanism includes a hinge door plate. The hinge door plate includes a second region opposite to the first region. The second region includes a second opening. The first region and the second region are opposite to each other. The reinforcing plate includes: a first portion. The first portion is stacked between the first and second regions. The first portion is used to cover the first and second openings.

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0049] In the accompanying drawings of the embodiments of this application, components are represented by straight guide lines with arrows; parts are represented by only straight guide lines; hollow structures such as cavities and openings, as well as surfaces, are represented by curved guide lines.

[0050] This application provides an electronic device. The electronic device can be a mobile phone, tablet computer, personal digital assistant (PDA), watch, e-reader, laptop, wearable device, or other foldable electronic device. For ease of explanation, the following embodiment uses a foldable mobile phone as an example.

[0051] Referring to Figure 1, the electronic device 100 may include a display assembly 10. The display assembly 10 includes a display screen 01. The display screen 01 may be a flexible display screen, which has the characteristics of high flexibility and bendability, and can provide users with a new interaction method based on its bendability. The display panel of the display screen 01 may be any one of the following: liquid crystal display (LCD), organic light-emitting diode (OLED), active-matrix organic light-emitting diode (AMOLED), flexible light-emitting diode (FLED), quantum dot light-emitting diode (QLED), etc., and this application embodiment does not limit this.

[0052] For the sake of clarity in the description of the embodiments below, an XYZ coordinate system is established for the electronic device 100 in its unfolded state as shown in Figure 1. The length direction of the electronic device 100 is defined as the X-axis, the width direction as the Y-axis, and the thickness direction as the Z-axis. It is understood that the coordinate system settings of the electronic device 100 can be flexibly set according to actual needs, and no specific limitations are made here.

[0053] Furthermore, referring to Figure 1, the electronic device 100 includes a first middle frame 20, a second middle frame 30, and a pivot mechanism 40 disposed between the first middle frame 20 and the second middle frame 30. The first middle frame 20 and the second middle frame 30 can be used to support the display screen 01, ensuring that the display screen 01 remains as flat as possible during use and protecting the display screen 01.

[0054] In addition, other electronic components, such as cameras, headphones, earpieces, buttons, batteries, etc., may be provided on the first middle frame 20 and the second middle frame 30. This application embodiment does not limit the other electronic components provided on the first middle frame 20 and the second middle frame 30.

[0055] Referring to Figure 1, the display screen 01 may include a foldable display section 11, a first non-foldable display section 12, and a second non-foldable display section 13. The foldable display section 11 is correspondingly disposed with the pivot mechanism 40. The first non-foldable display section 12 is correspondingly disposed with the first middle frame 20. The second non-foldable display section 13 is correspondingly disposed with the second middle frame 30. When the display screen 01 is in a flattened state, the first non-foldable display section 12, the foldable display section 11, and the second non-foldable display section 13 are distributed along a direction perpendicular to the thickness direction of the display screen 01 (X-axis direction). The first non-foldable display section 12 can be connected to the first middle frame 20, and the second non-foldable display section 13 can be connected to the second middle frame 30.

[0056] The above embodiments, as shown in Figure 1, are illustrative examples using a dual-screen electronic device 100. The electronic device 100 involved in these embodiments can also be a device with more screens, such as a three-screen foldable device, a four-screen foldable device, etc. These embodiments are not specifically limited.

[0057] The electronic device 100 shown in Figure 1 is in an unfolded state. In the unfolded state, the angle between the first non-folding display unit 12 and the second non-folding display unit 13 can be approximately 180°. That is, in the unfolded state of the display screen 01 shown in Figure 1, the first non-folding display unit 12, the foldable display unit 11, and the second non-folding display unit 13 are arranged sequentially along the X-axis. In this way, the electronic device 100 can be folded laterally.

[0058] Alternatively, in some other embodiments of this application, when the display screen 01 is in the unfolded state, the first non-foldable display section 12, the foldable display section 11, and the second non-foldable display section 13 may be arranged sequentially along the Y-axis. In this way, the electronic device 100 can be folded vertically. When the display screen 01 is in the unfolded state, a large-screen display can be achieved to provide users with richer information.

[0059] Referring to Figure 2 (a structural schematic diagram of the electronic device 100 in the folded state in Figure 1), the inward folded state of the electronic device 100 is shown, that is, the electronic device 100 bends towards the side where the display screen 01 (as shown in Figure 1) is located. When the electronic device 100 is in the inward folded state, the first middle frame 20 and the second middle frame 30 can move closer to each other, so that the first non-folding display part 12 (as shown in Figure 1) and the second non-folding display part 13 (as shown in Figure 1) can move closer to each other.

[0060] In some other embodiments of this application, the electronic device 100 may also fold outward, that is, the electronic device 100 bends away from the side where the display screen 01 is located. When the electronic device 100 folds outward, the first non-folding display unit 12 and the second non-folding display unit 13 may move closer to each other.

[0061] Referring to Figure 3 (an exploded view of the electronic device 100 in Figure 1), the display assembly 10 may further include a support assembly 02. The support assembly 02 includes a support member 21. The support member 21 is disposed on the side of the display 01 opposite to the light-emitting surface L of the display 01. The display 01, the support member 21, and the pivot mechanism 40 are stacked. The support member 21 is used to increase the structural strength of the display 01, and the support member 21 can be folded together with the display 01. The support member 21 may also be called a bamboo book, and the bamboo book material may be carbon fiber. Alternatively, the support member 21 may also be a thin metal material, such as stainless steel, titanium alloy, copper alloy, or aluminum alloy. The support member 21 can provide support for the display 01, which helps ensure the overall flatness of the display 01, and thus helps ensure the compression resistance of the electronic device 100. The support member 21 may include a bendable portion 211, a first non-bendable portion 212, and a second non-bendable portion 213. When the display screen 01 is in the flattened state, the bendable portion 211 is located between the first non-bendable portion 212 and the second non-bendable portion 213. The bendable portion 211 is disposed opposite to the pivot mechanism 40. The pivot mechanism 40 can drive the bendable portion 211 and the display screen 01 to bend or flatten, thereby allowing the display screen 01 to switch between the flattened state and the folded state.

[0062] Referring to Figure 4 (an enlarged view of the electronic device 100 shown in Figure 3 at point A), a first opening 2112 is provided on the first region 2111 of the bendable portion 211 (the dotted line portion in the figure) to facilitate folding of the support member 21 (as shown in Figure 3). This reduces the rebound force of the support member 21 when the electronic device 100 is bent, making it easier to bend the electronic device 100.

[0063] Referring to Figure 3, the pivot mechanism 40 may include pivot door panels 41. Exemplarily, the pivot mechanism 40 may include two pivot door panels 41, which are used to move towards or away from each other to switch the display screen 01 between an unfolded state and a folded state along the bending line M. The two pivot door panels 41 can be rotatably connected by a pivot, hinge, etc., which is not specifically limited in this application.

[0064] Referring to Figure 5 (an enlarged view of the electronic device 100 shown in Figure 3 at point B), the hinge panel 41 includes a second region 411 (as shown by the dashed line in the figure). Along the Z-axis, the second region 411 and the first region 2111 (as shown in Figure 4) are opposite each other. A second opening 412 is typically designed on the second region 411 of the hinge panel 41. The second opening 412 is used to avoid or connect and fix other components (such as hinges, etc., not shown in the figure). Because the second opening 412 cannot provide support for the support member 21 (as shown in Figure 3), the support capacity of the second region 411 for the bendable portion 211 of the support member 21 (as shown in Figure 3) and the display screen 01 (as shown in Figure 3) is poor. Referring to Figure 4, since the first region 2111 of the bendable portion 211 has a first opening 2112, the support performance of the first region 2111 for the display screen 01 is limited.

[0065] When the second region 411 (as shown in Figure 5) provides insufficient support to the first region 2111 (as shown in Figure 4), and the first region 2111 also provides insufficient support to the display screen 01 (as shown in Figure 3), the compressive force exerted by the second opening 412 on the display screen 01 is significantly lower than in other locations. When the display screen 01 is in a semi-folded state or is subjected to compression, the display screen 01 located on the first region 2111 side may exhibit bright spots or black spots, failing to meet normal usage requirements. In the bending area of ​​the display screen 01, the proportion of bright spots and black spots exceeding 60% of the total number of bright spots and black spots can reach over 60%.

[0066] To address the aforementioned issues, referring to FIG3, the support assembly 02 of the electronic device 100 provided in this embodiment may further include a reinforcing plate 22. Referring to FIG6 (a cross-sectional view of an electronic device 100 shown in FIG1 along the P1-P2 direction), the reinforcing plate 22 may include a first portion 221. The first portion 221 is stacked between the first region 2111 and the second region 411. The reinforcing plate 22 separates the second region 411 and the first region 2111 of the bendable portion 211. The first portion 221 is used to cover the first opening 2112 and the second opening 412. This ensures that when the first region 2111 of the bendable portion 211 is subjected to a force along the Z-axis toward the pivot door panel 41, the force can be transmitted to the reinforcing plate 22. This ensures that the reinforcing plate 22 can provide support for the bendable portion 211 and the display screen 01. Thus, the first region 2111 of the support member 21 and the display screen 01 can be supported by means of the reinforcing plate 22. Especially when the display screen 01 is in a semi-folded state or is compressed, it improves the situation where bright spots or black spots appear in the area of ​​the display screen 01 due to insufficient support. Furthermore, the support provided to the display screen 01 by the first part 221 of the reinforcing plate 22 can also improve the compression and impact resistance of the electronic device 100.

[0067] When a point-pinch capability test is performed on the areas on both sides of the bend line M (as shown in FIG. 1) of the electronic device 100 provided in this application embodiment (i.e., the area along the Z-axis where the display screen 01 is located directly above the hinge door panel 41), the point-pinch capability of the electronic device 100 provided in this application embodiment can be increased from 1.8 kg to 5.6 kg. This represents an increase of 211%. When a single-line crushing capability test is performed on the areas on both sides of the bend line M of the electronic device 100's display screen 01, the single-line crushing capability of the electronic device 100 provided in this application embodiment can be increased from 1.755 kg to 4.5 kg. This represents an increase of 139%.

[0068] As an example, the second region 411 described above may also have features such as steps or screws (not shown in the figure). Because of these features, the second region 411 is a non-complete planar structure. This results in discontinuous support between the second region 411 and the first region 2111 and the display screen 01. The first portion 221 of the reinforcing plate 22 is disposed between the first region 2111 and the second region 411, providing support for the first region 2111 and the display screen 01. This improves the problems of bright spots and black spots on the display screen 01.

[0069] Referring to Figure 6, the hinge mechanism 40 also includes a gap G between the two hinge panels 41. The second region 411 may include at least a portion of the gap G. The support capacity for the support member 21 and the display screen 01 at the gap G is also relatively poor. The reinforcing plate 22 can cover at least a portion of the gap G and support the support member 21 and the display screen 01. This further improves the support provided by the reinforcing plate 22 to the display screen 01 and improves the bright spots and black spots on the display screen 01.

[0070] Referring to Figure 7 (a cross-sectional view of the electronic device 100 in a semi-bent state), the first part 221 includes two first sub-regions 2211 located on the two pivot panels 41, and a second sub-region 2212 located between the two pivot panels 41. The pivot mechanism 40 also includes a pivot arc arm 42. The pivot arc arm 42 is connected to the two pivot panels 41. At least a portion of the projection of the pivot arc arm 42 onto the reinforcing plate 22 is located in the second sub-region 2212. The pivot arc arm 42 and the two pivot panels 41 can rotate in coordination, thereby causing the display screen 01 to fold or unfold. The two first sub-regions 2211 of the first part 221 located on the two pivot panels 41 can cover the first opening 2112 and the second opening 412. The second sub-region 2212 of the first part 221 located between the two pivot panels 41 can cover at least a portion of the pivot arc arm 42. When the electronic device 100 falls while hovering, it is to prevent the flexible part 211 from colliding with the pivot arm 42 after the flexible part 211 swings, which could cause black spots or bright spots on the display screen 01.

[0071] When conducting a drop test on the electronic device 100 provided in this application embodiment, a drop from 1.2m would result in black spots or bright spots due to the bending portion 211 swinging and colliding with the pivot arm 42. This performance has been improved to the point that a drop from 1.5m will not result in black spots or bright spots due to the impact of the bending portion 211 with the pivot arm 42. The drop performance of the electronic device 100 in a hovering scenario has been greatly improved.

[0072] Referring to Figure 8 (a partial schematic diagram of the electronic device 100 after removing the display screen 01 and the support member 21), along the bending line M of the display screen 01 (as shown in Figure 3) (as shown in Figure 1), the pivot mechanism 40 includes a first end a and a second end b. The first end a and the second end b are located at the edge of the electronic device 100. The first part 221 includes a first sub-part 2213 and a second sub-part 2214. The first sub-part 2213 is located near the first end a, and the second sub-part 2214 is located near the second end b. To avoid obstruction or for connection and fixation, along the bending line M of the display screen 01, the portion of the pivot mechanism 40 near the first end a and the portion near the second end b are provided with multiple second openings 412. The first sub-part 2213, located near the first end a, can cover the second openings 412 near the first end a. The second sub-part 2214, located near the second end b, can cover the second openings 412 near the second end b. The reinforcing plate 22 can block more of the second opening 412, improving the support provided to the bendable part 211 (as shown in Figure 3) and the display screen 01.

[0073] Referring to Figure 4, the bendable portion 211 may include a third region 2113, and the third region 2113 may include a third opening 2114. In some embodiments, the first opening 2112 and the third opening 2114 may be different regions of a strip opening.

[0074] Referring to Figure 9 (a partial schematic diagram of another electronic device 100 after removing the display screen 01 and the support member 21), the first part 221 also includes a third sub-part 2215. The third sub-part 2215 is disposed between the first sub-part 2213 and the second sub-part 2214. The third sub-part 2215 is used to cover the third opening 2114 (as shown in Figure 4). By covering the third opening 2114 in the third region 2113 (as shown in Figure 4) of the bendable part 211 (as shown in Figure 4) with the third sub-part 2215, the supporting effect of the reinforcing plate 22 on the bendable part 211 is further improved.

[0075] The above embodiment, as shown in Figure 9, is an example illustrating how the third sub-part 2215 is connected to the first sub-part 2213 and the second sub-part 2214, allowing the reinforcing plate 22 to extend from the first end a to the second end b. In other embodiments of this application, the third sub-part 2215 may also be spaced apart from the first sub-part 2213 and the second sub-part 2214. The number of third sub-parts 2215 may be one or more. This application does not impose specific limitations on the embodiments.

[0076] Referring to Figure 10 (a cross-sectional view of another electronic device 100 along the P1-P2 direction as shown in Figure 1), the reinforcing plate 22 includes a second portion 222 connected to the first portion 221. The second portion 222 includes opposing first surfaces S1 and second surfaces S2. The first surface S1 of the second portion 222 is connected to the first non-bending portion 212. This fixes the reinforcing plate 22 so that it can be stably positioned between the support member 21 and the pivot mechanism 40. Referring to Figure 11 (a structural schematic diagram of the display assembly 10 in a folded state), when the display 01 is bent, the first portion 221 bends. During the bending process, the first portion 221 can slide relative to the support member 21. When the electronic device 100 is bent, the portion of the reinforcing plate 22 located between the bendable portion 211 and the pivot mechanism 40 can slide relative to the support member 21 to reduce the rebound force during bending and prevent the electronic device 100 from failing to close due to excessive bending stress of the reinforcing plate 22.

[0077] The above embodiments, as shown in Figures 10 and 11, are illustrative examples illustrating the connection between the second portion 222 of the reinforcing plate 22 and the first non-bending portion 212. In other embodiments of this application, the second portion 222 of the reinforcing plate 22 may also be connected to the second non-bending portion 213. The embodiments of this application are not specifically limited.

[0078] For example, continuing to refer to FIG10, the first surface S1 and the first non-bending portion 212 can be bonded and fixed by adhesive 50. Adhesive 50 may include at least one of double-sided adhesive, hot melt adhesive, backing adhesive, thermosetting adhesive, and shadowless adhesive. Adhesive 50 composed of any one or more of the above adhesives provides a more reliable bond, thereby improving the connection stability between the second portion 222 and the first non-bending portion 212.

[0079] Referring to Figure 11, the reinforcing plate 22 can be connected to the first non-bending portion 212 to form a support assembly 02. The support assembly 02 and the display screen 01 together constitute the display screen assembly 10. During the manufacturing process, the second part 222 of the reinforcing plate 22 can be glued to the first non-bending portion 212. Then, the entire display screen assembly 10 is connected to the first middle frame 20 (as shown in Figure 3).

[0080] Referring to Figure 11, after the second part 222 of the reinforcing plate 22 is bonded to the support member 21, an adhesive (not shown in the figure) can also be applied to the second surface S2 of the second part 222 facing away from the support member 21, and a separation paper (not shown in the figure) can be applied to the surface of the adhesive facing away from the second part 222 to form the display assembly 10. When the display assembly 10 is connected to the pivot mechanism 40, the separation paper can be removed, and then the adhesive can be applied to the first middle frame 20 (as shown in Figure 3) to form the electronic device 100 as shown in Figure 12 (a cross-sectional view of another electronic device 100 along the P1-P2 direction as shown in Figure 1). The first surface S1 of the second part 222 of the electronic device 100 is connected to the first non-bending part 212, and the second surface S2 of the second part 222 is connected to the first middle frame 20. This double-sided fixation of the reinforcing plate 22 further improves the fixation reliability of the reinforcing plate 22.

[0081] In some other embodiments, referring to FIG13 (a cross-sectional view of another electronic device 100 as shown in FIG1 along the P1-P2 direction), the second surface S2 of the second part 222 is connected to the first middle frame 20 to fix the reinforcing plate 22.

[0082] For example, the second part 222 and the first middle frame 20 can be fixed by adhesive 50 or by screws (not shown in the figure). This application does not make specific limitations.

[0083] The above embodiments, as shown in Figure 12 or Figure 13, are illustrative examples illustrating the connection between the second portion 222 of the reinforcing plate 22 and the first middle frame 20. In other embodiments of this application, the second portion 222 of the reinforcing plate 22 may also be connected to the second middle frame 30. The embodiments of this application are not specifically limited.

[0084] Referring to Figure 14 (a cross-sectional view of another electronic device 100 shown in Figure 1 along the P1-P2 direction), the reinforcing plate 22 also includes a third part 223. The third part 223 is connected to the first part 221. When the display screen 01 is in a flattened state, the third part 223 is located on the side of the first part 221 facing away from the second part 222. The third part 223 of the reinforcing plate 22 can increase the friction between the reinforcing plate 22 and the support member 21 or the second middle frame 30. This prevents the reinforcing plate 22 from experiencing sudden changes in force during bending, which could lead to asynchronous bending deformation.

[0085] Referring to Figure 15 (a partial schematic diagram of another electronic device 100 after removing the display screen 01 and the support member 21), the width w1 of the third part 223 is smaller than the width w2 of the first part 221. This facilitates the third part 223 to avoid interference with other components in the electronic device 100 (such as the motherboard, battery, etc.).

[0086] The above embodiments are illustrative examples assuming that the second region 411 (as shown in FIG. 6) may include at least a portion of the gap G (as shown in FIG. 6), and the reinforcing plate 22 covers the second region 411. In other embodiments of this application, referring to FIG. 16, the second region 411 may not include the gap G, and the reinforcing plate 22 may only cover the second opening 412 and the surrounding area. The embodiments of this application are not specifically limited.

[0087] Referring to Figure 17 (a partial schematic diagram of another electronic device 100 after removing the display screen 01 and the support member 21), the reinforcing plate 22 includes clearance holes 224. Referring to Figure 18 (a cross-sectional view of another electronic device 100 shown in Figure 1 along the P1-P2 direction), the electronic device 100 includes an adhesive layer 60. The adhesive layer 60 is disposed on the surface of the bendable portion 211 away from the display screen 01. The adhesive layer 60 is disposed in the clearance holes 224. The adhesive layer 60 is cleared by the clearance holes 224 on the reinforcing plate 22. This ensures that the bendable portions 211 located on both sides of the reinforcing plate 22 and the pivot mechanism 40 can be connected through the adhesive layer 60. In addition, the clearance holes 224 on the reinforcing plate 22 can reduce the stress when the reinforcing plate 22 is bent, thereby reducing the rebound force when the reinforcing plate 22 is bent and reducing the impact of the reinforcing plate 22 on the bending of the electronic device 100.

[0088] Referring to Figure 18, the adhesive layer 60 can be bonded to the fixing region 2115 of the bendable portion 211. Along the Y-axis direction, the fixing region 2115 can be located on one side of the first region 2111. Alternatively, the bendable portion 211 includes two fixing regions 2115 located on opposite sides of the first region 2111. Each fixing region 2115 is fixed to the rotating shaft mechanism 40 by at least one adhesive layer 60.

[0089] For example, the adhesive layer 60 described above may include at least one of hot melt adhesive, backing adhesive, thermosetting adhesive, and UV-curing adhesive. The adhesive layer 60 composed of one or more of the above adhesives provides a more reliable bond, thereby improving the connection stability between the bendable portion 211 and the rotating shaft mechanism 40.

[0090] Referring to Figure 18, the reinforcing plate 22 may include a lubricating layer 225 and a supporting layer 226 stacked together. The lubricating layer 225 is disposed on the surface of the supporting layer 226 facing or away from the display screen 01 and is connected to the supporting layer 226. The lubricating layer 225 disposed on the surface of the supporting layer 226 can reduce the friction between the reinforcing plate 22 and the supporting member 21 or the rotating shaft mechanism 40 when the reinforcing plate 22 is bent, thereby facilitating the bending of the reinforcing plate 22. The lubricating layer 225 can also improve the wear resistance of the reinforcing plate 22.

[0091] Referring to Figure 18, along the Z-axis, the clearance hole 224 can penetrate the support layer 226 and the lubrication layer 225. This ensures that the adhesive layer 60 can be connected to the bendable portion 211 located on both sides of the reinforcing plate 22 and the rotating shaft mechanism 40, respectively.

[0092] The above embodiment, as shown in Figure 18, is an example illustrating that the support layer 226 has lubrication layers 225 on both sides facing or away from the display screen 01. In other embodiments of this application, the lubrication layer 225 may be provided only on the side of the support layer 226 facing the display screen 01. Alternatively, the lubrication layer 225 may be provided only on the side of the support layer 226 away from the display screen 01.

[0093] For example, the material of the lubricating layer 225 shown in FIG18 may include Teflon or polyethylene terephthalate (PET). Both the Teflon coating and the PET film have a low coefficient of friction, ensuring that the friction between the reinforcing plate 22 and the support member 21 or the rotating shaft mechanism 40 is small when the reinforcing plate 22 slides. Teflon has excellent wear resistance and corrosion resistance, ensuring the service life of the lubricating layer 225.

[0094] As shown in Figure 19 (an enlarged view of Figure 18 at point C), the thickness h1 of the lubricating layer 225 can be 0.01 mm to 0.1 mm. For example, the thickness h1 of the lubricating layer 225 can be 0.01 mm, 0.02 mm, 0.04 mm, 0.06 mm, 0.08 mm, 0.1 mm, etc. A thickness h1 greater than or equal to 0.01 mm can prevent damage to the lubricating layer 225 when the electronic device 100 is bent, thus ensuring lubrication effectiveness. A thickness h1 less than or equal to 0.1 mm prevents an increase in the size of the electronic device 100 due to an excessively large thickness h1.

[0095] For example, the support layer 226 shown in FIG19 is made of a metallic material. For example, the support layer 226 can be made of stainless steel, titanium alloy, etc. Metallic materials (such as stainless steel and titanium alloy) have high hardness, which can meet the support capacity required by the reinforcing plate 22.

[0096] As shown in Figure 19, the thickness h2 of the support layer 226 is 0.01mm-0.1mm. For example, the thickness h2 of the support layer 226 can be 0.01mm, 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc. A thickness h2 greater than or equal to 0.01mm ensures the rigidity of the support layer 226, thereby guaranteeing the supporting capacity of the reinforcing plate 22 for the support member 21 (as shown in Figure 3) and the display screen 01 (as shown in Figure 3). A thickness h2 less than or equal to 0.1mm avoids increasing the stress on the reinforcing plate 22 during bending due to excessive thickness of the support layer 226, thus reducing the impact of the reinforcing plate 22 on the bending of the electronic device 100 (as shown in Figure 3). A thickness h2 less than or equal to 0.1mm prevents an increase in the size of the electronic device 100 due to excessive thickness of the support layer 226.

[0097] This application provides an electronic device, a display assembly, a support assembly, and a reinforcing plate. The electronic device includes a stacked display assembly and a hinge mechanism. The display assembly includes a display screen and a support assembly. The support assembly includes a support member and a reinforcing plate. The support member is disposed on the side opposite to the light-emitting surface of the display screen.

The hinge mechanism includes a hinge panel, which includes a second region, which includes a second opening. The first region and the second region are opposite to each other. The electronic device includes a reinforcing plate, with a first portion of the reinforcing plate disposed between the first region and the second region. By providing the reinforcing plate, the display screen is supported, thereby improving the situation where bright spots or black spots appear in the relevant area of ​​the display screen due to insufficient support. The first part includes: two first sub-regions located on the two hinge door panels, and a second sub-region located between the two hinge door panels. The hinge mechanism also includes a hinge arc arm connected to the two hinge door panels, and at least a portion of the projection of the hinge arc arm onto the reinforcing plate is located in the second sub-region. The second sub-region prevents the bendable part from colliding with the hinge arc arm, thus avoiding black spots or bright spots on the display screen. The reinforcing plate also includes a second part. The second part is connected to the first non-bending part; and / or, the electronic device includes a first mid-frame, and the second part is connected to the first mid-frame. This further secures the reinforcing plate, allowing it to be stably positioned between the support member and the hinge mechanism.
