[0024] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0025] In the related art, in order to allow the support plate of the screen to be bent in coordination with the screen, a plurality of through holes are often provided at the portion of the support plate that needs to be bent, and the support plate is partially hollowed out, so that the support plate has better bending performance. However, this also causes the impact resistance of the portion of the support plate that can be bent to be greatly weakened.

[0026] Parts such as rotating shafts are often set under the support plate, and there are many gaps and step differences between the parts. When the front of the screen is impacted, the bendable part of the support plate contacts the parts below and deforms, causing the support plate under the screen to be uneven and damage the screen.

[0027] In order to solve the above technical problems, according to an embodiment of the present disclosure, a board body, a screen assembly and an electronic device are provided, wherein the board body includes: a first supporting layer, the first supporting layer supports the folding screen, the first supporting layer is provided with a first bending portion and a first supporting portion; and a second supporting layer, the second supporting layer is stacked with the first supporting layer, the second supporting layer is provided with a second supporting portion, wherein the first bending portion and the second supporting portion are overlapped in the thickness direction of the board body; the first supporting portion and the second supporting portion are overlapped in the thickness direction of the board body and are fixedly connected.

[0028] The present invention divides a plate body into a first supporting layer and a second supporting layer which are stacked, and overlaps the second supporting portion of the second supporting layer with the first bending portion of the first supporting layer in the thickness direction of the plate body, so that the second supporting portion provides support for the first bending portion, thereby improving the impact resistance of the first bending portion while ensuring the bending performance of the first bending portion.

[0029] It can be understood that the board involved in the present disclosure can be applicable to any terminal listed below.

[0030] It is understandable that the terminal involved in the present disclosure may also be referred to as a terminal device, a user equipment (User Equipment, UE), a mobile station (Mobile Station, MS), a mobile terminal (Mobile Terminal, MT), etc., which is a device that provides voice and / or data connectivity to users. For example, the terminal may be a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminals are: a smart phone (Mobile Phone), a pocket computer (Pocket Personal Computer, PPC), a handheld computer, a personal digital assistant (Personal Digital Assistant, PDA), a laptop computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device may also be a vehicle-mounted device. It should be understood that the embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0031] Figure 1 It is a schematic structural diagram of a plate body according to an exemplary embodiment. Figure 2 is a schematic structural diagram of a plate body according to another exemplary embodiment.

[0032] In some embodiments, Figure 1 and Figure 2 As shown, the plate body includes: a first supporting layer 10 and a second supporting layer 20 .

[0033] The plate body can be a plate-like component used to support the folding screen. By arranging the plate body under the folding screen, the plate body can provide support and limiting effects for the folding screen, limit the deformation of the folding screen, and enhance the user experience of using the folding screen.

[0034] Exemplarily, the plate body may be a stainless steel plate body, a titanium alloy plate body or a carbon fiber plate body, and the first supporting layer 10 and the second supporting layer 20 may be a stainless steel layer, a titanium alloy layer or a carbon fiber layer.

[0035] The first supporting layer 10 may be a component that contacts the folding screen and directly supports the folding screen, and the first supporting layer 10 may be provided with a first bending portion 11 and a first supporting portion 12 .

[0036] Since the folding screen can be changed into a folded state or an unfolded state by bending, in order to enable the plate to provide support for the folding screen in real time, a first bending portion 11 with high bendability is provided on the first supporting layer 10, so that the first supporting layer 10 can bend along with the folding screen to adapt to different bending states of the folding screen and can still provide support for the folding screen when the folding screen is bent to different angles.

[0037] The first support portion 12 may be the portion of the first support layer 10 excluding the bent portion. The first support portion 12 has high rigidity and can provide good support for the folding screen.

[0038] The second supporting layer 20 may be stacked with the first supporting layer 10 , and the first supporting layer 10 and the second supporting layer 20 may be two layers stacked on the plate.

[0039] The second supporting layer 20 may be provided with a second supporting portion 22. The second supporting portion 22 has high rigidity and can provide good support for the folding screen.

[0040] The first support portion 12 and the second support portion 22 may be overlapped and fixedly connected in the thickness direction of the plate body, so that the first support layer 10 and the second support layer 20 are stacked and fixedly connected through the connection relationship between the first support portion 12 and the second support portion 22 .

[0041] The first bending portion 11 and the second supporting portion 22 can be overlapped in the thickness direction of the plate, so that the second supporting portion 22 provides support for the first bending portion 11, thereby improving the impact resistance of the first bending portion 11 while ensuring the bending performance of the first bending portion 11.

[0042] The present invention divides a plate body into a first supporting layer 10 and a second supporting layer 20 which are stacked, and overlaps the second supporting portion 22 of the second supporting layer 20 with the first bending portion 11 of the first supporting layer 10 in the thickness direction of the plate body, so that the second supporting portion 22 provides support for the first bending portion 11, thereby improving the impact resistance of the first bending portion 11 while ensuring the bending performance of the first bending portion 11.

[0043] In some embodiments, the second supporting side layer is separately arranged from the first bending portion 11, so as to avoid the second supporting layer 20 affecting the bending performance of the first bending portion 11, thereby ensuring that the first supporting layer 10 can bend along with the folding screen to adapt to different bending states of the folding screen. When the folding screen is bent to different angles, the plate body can still provide support for the folding screen.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, the second support layer 20 may include a second bending portion 21, and the second bending portion 21 may be a portion with higher bending performance on the second support layer 20. By providing the second bending portion 21 with higher bendability on the second support layer 20, the second support layer 20 can be bent along with the folding screen, and will not hinder the bending effect of the first support layer 10, so that the plate body can adapt to different bending states of the folding screen, and can still provide support for the folding screen when the folding screen is bent to different angles.

[0045] The second bending portion 21 can be overlapped with the first supporting portion 12 in the thickness direction of the plate, so that the first supporting portion 12 provides support for the second bending portion 21, while ensuring the bending performance of the second bending portion 21, and improving the impact resistance of the second bending portion 21.

[0046] In some embodiments, since the first bending portion 11 is the part with the greatest bending degree of the plate body and the folding screen, the second bending portion 21 is arranged near the first bending portion 11 on the orthographic projection of the first supporting layer 10. This can ensure that the second bending portion 21 is still supported by the first supporting portion 12 while the second bending portion 21 of the second supporting layer 20 is as close as possible to the part with the greatest bending degree of the plate body, thereby ensuring the overall bending performance of the plate body and allowing the plate body to bend along with the folding screen to adapt to different bending states of the folding screen. When the folding screen is bent to different angles, the plate body can still provide support for the folding screen.

[0047] Figure 4 The figure is a schematic diagram of a top view structure of a second supporting layer of a plate body according to an exemplary embodiment.

[0048] In some embodiments, Figure 4 As shown, the second bending portion 21 may be provided with a break 40, thereby dividing the second supporting layer 20 into two spaced apart plate-like parts. By dividing the second supporting layer 20 into two separate parts, the overall bending performance of the second supporting layer 20 is improved.

[0049] Figure 5 The figure is a schematic diagram of a top view structure of a second supporting layer of a plate body according to another exemplary embodiment.

[0050] In some embodiments, Figure 5 As shown, the second bending portion 21 may be provided with a plurality of through holes 30 penetrating the second supporting layer 20. The through holes 30 may hollow out a portion of the second supporting layer 20, so that the portion of the second supporting layer 20 provided with the through holes 30 may have better bending performance, thereby ensuring the bending performance of the entire plate body, so that the plate body may bend along with the folding screen to adapt to different bending states of the folding screen. When the folding screen is bent to different angles, the plate body may still provide support for the folding screen.

[0051] In other embodiments, the second bending portion 21 may also be provided with a plurality of through holes 30 and slits 40 penetrating the second supporting layer 20 .

[0052] Figure 3 The figure is a schematic top view of the structure of a first supporting layer of a plate body according to an exemplary embodiment.

[0053] In some embodiments, Figure 3As shown, the first support layer 10 may further include a third bending portion 13, and the third bending portion 13 may be arranged at intervals on both sides of the first bending portion 11. The third bending portion 13 may be a portion of the first support layer 10 with good bending performance, so that the first support layer 10 can be bent along with the folding screen to adapt to different bending states of the folding screen, and can still provide support for the folding screen when the folding screen is bent to different angles.

[0054] The third bending portion 13 can be overlapped with the second supporting portion 22 in the thickness direction of the plate body, and the third bending portion 13 and the second supporting portion 22 can be overlapped in the thickness direction of the plate body, so that the second supporting portion 22 provides support for the third bending portion 13, while ensuring the bending performance of the third bending portion 13, the impact resistance of the third bending portion 13 is improved.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 is 115 microns to 125 microns, that is, the thickness of the plate is 115 microns to 125 microns. Exemplarily, the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 can be 120 microns.

[0056] Setting the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 to 115 microns to 125 microns can ensure that the plate body maintains sufficient supporting strength while maintaining the bending performance of the bending portion and minimize the increase in screen thickness caused by the plate body.

[0057] The present disclosure is not limited thereto, and the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 may also be adjusted according to the materials of the first supporting layer 10 and the second supporting layer 20 .

[0058] In some embodiments, Figure 1 and Figure 2 As shown, the thickness H2 of the second support layer 20 can be less than 30 microns. Since the second support portion 22 of the second support layer 20 overlaps with the first bending portion 11 of the first support layer 10 in the thickness direction of the plate body, the thickness H2 of the second support layer 20 is configured to be less than 30 microns, so that the second support portion 22 has a certain bending performance, thereby preventing the second support portion 22 from hindering the bending of the first bending portion 11, thereby ensuring the bending performance of the entire plate body, so that the plate body can bend with the folding screen to adapt to different bending states of the folding screen, and the plate body can still provide support for the folding screen when the folding screen is bent to different angles.

[0059] In some embodiments, Figure 1As shown, the first support portion 12 and the second support portion 22 can be connected by welding. Welding can reduce the size of the cross section of the component, thereby saving metal materials, reducing the weight of the structure, and improving the economic benefits of the product.

[0060] In some embodiments, Figure 2 As shown, the board body may include an adhesive layer 50 .

[0061] The adhesive layer 50 may be an adhesive component and may be disposed between the first support portion 12 and the second support portion 22 so that the adhesive layer 50 may bond and connect the first support portion 12 and the second support portion 22 , thereby enabling the first support layer 10 and the second support layer 20 to be stacked, connected and fixed.

[0062] The bonding connection is easy to process, which helps to reduce the intermediate links in the board production process, simplify the production process and reduce production costs.

[0063] In some embodiments, Figure 2 As shown, the thickness H3 of the adhesive layer 50 can be 8 microns to 12 microns, and the sum of the thickness H1 of the first supporting layer 10, the thickness H2 of the second supporting layer 20 and the thickness H3 of the adhesive layer 50 is 115 microns to 125 microns, that is, the thickness of the plate is 115 microns to 125 microns. Exemplarily, the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 can be 120 microns.

[0064] Setting the sum of the thickness H1 of the first supporting layer 10, the thickness H2 of the second supporting layer 20 and the thickness H3 of the adhesive layer 50 to 115 microns to 125 microns can ensure that the board body maintains sufficient supporting strength while maintaining the bending performance of the bending portion and minimize the increase in screen thickness caused by the board body.

[0065] The present disclosure is not limited thereto, and the sum of the thickness H1 of the first supporting layer 10 and the thickness H2 of the second supporting layer 20 may also be adjusted according to the materials of the first supporting layer 10 and the second supporting layer 20 .

[0066] Based on the same concept, the embodiment of the present disclosure also provides a screen assembly, which may include: a folding screen; a plate body, the folding screen may be arranged on the surface of the first supporting layer 10, the plate body may provide support and limiting effects for the folding screen, limit the deformation of the folding screen, and enhance the user experience of using the folding screen.

[0067] Among them, the folding screen can be a bendable flexible screen, or the folding screen can be a combination of multiple rigid screens.

[0068] The present invention divides a plate body into a first supporting layer 10 and a second supporting layer 20 which are stacked, and overlaps the second supporting portion 22 of the second supporting layer 20 with the first bending portion 11 of the first supporting layer 10 in the thickness direction of the plate body, so that the second supporting portion 22 provides support for the first bending portion 11. While ensuring the bending performance of the first bending portion 11, the impact resistance of the screen assembly corresponding to the first bending portion 11 is improved, thereby improving the reliability of the screen assembly.

[0069] Based on the same concept, an embodiment of the present disclosure also provides an electronic device.

[0070] The electronic device may be a laptop computer, a desktop computer, a mobile phone, a digital broadcast terminal, a message transceiver, a game console, a tablet device, a medical device, a fitness device, a personal digital assistant, a translator, and a wearable device such as a watch or a bracelet, and may be any electronic device having a plate body.

[0072] The present invention divides a plate body into a first supporting layer 10 and a second supporting layer 20 which are stacked, and overlaps the second supporting portion 22 of the second supporting layer 20 with the first bending portion 11 of the first supporting layer 10 in the thickness direction of the plate body, so that the second supporting portion 22 provides support for the first bending portion 11. While ensuring the bending performance of the first bending portion 11, the impact resistance of the folding screen corresponding to the first bending portion 11 is improved, thereby improving the reliability of the electronic device.
