The bottom wall 231 of the support 23 is provided with a folding portion 233 corresponding to the above-described folding region 201 so that the folding portion 233 is folded in synchronization with the folding region 201 when the display screen 21 is folded. In other words, the support 23 serves to support the display screen 21 and to be folded synchronously when the display screen 21 is folded. As in the previous embodiments, in the present embodiment, the support 23 may be made of steel sheet, which has a thickness of about 0.15mm. It will be appreciated that the folding mechanism provided on the housing assembly 10 of the electronic device is provided in correspondence with the folding portion 233 to enable synchronous folding when the display screen 21 is folded.
The supporting member 23 made of the steel sheet having the above thickness is realized by forming the through hole in the folded portion 233 in order to provide a good folding effect. Referring to fig. 6 in combination, fig. 6 is a schematic structural diagram of the supporting member 23 in the embodiment of fig. 5, in which the X direction is substantially the A-A direction shown in fig. 2, the Y direction is substantially the B-B direction shown in fig. 2, and the Z direction is substantially the thickness direction of the electronic device 100 in fig. 2. The electronic device 100 in the embodiment of the present application is configured as a foldable electronic device that is foldable around the X direction.
Further, the folded portion 233 of the support 23 is provided with a plurality of through holes 2331. It should be noted that in the description of the embodiments of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless explicitly defined otherwise. Specifically, the through holes 2331 are sequentially arranged at intervals in the X direction, and/or the through holes 2331 are arranged in a row in the Y direction. For example, the through holes 2331 may be arranged in one row or in a plurality of rows in the Y direction. Here, the plurality of columns is at least two columns, for example, two columns, three columns, and the like. When the through holes 2331 are arranged in a plurality of rows along the Y direction, the through holes 2331 are alternately arranged along the Y direction. The staggered distribution of the through holes 2331 in the Y direction can avoid affecting the structural strength of the support 23 due to the open holes. Of course, in other embodiments, the through holes 2331 may be distributed in a queue to have better appearance.
Further, the pitch of the holes of the through holes 2331 arranged in the X direction is 50-1000 μm, and the pitch of the columns of the through holes 2331 arranged in the Y direction is 50-1000 μm. It will be appreciated that too small a hole spacing of the through holes 2331 is detrimental to folding and too large a hole spacing of the through holes 2331 can affect the overall structural strength of the support 23. In the embodiment of the present application, in order to maintain a good folding effect and ensure a good structural strength of the supporting member 23, the through holes 2331 are sequentially arranged at a hole pitch of 150 μm along the X direction, and the through holes 2331 are arranged at a column pitch of 150 μm along the Y direction in a plurality of columns.
Further, the through hole 2331 has a first length L1 in the X direction, and the through hole 2331 has a second length L2 in the Y direction, wherein the first length L1 is substantially not less than the second length L2. For example, the first length L1 is approximately 5-35mm and the second length L2 is approximately 50-1000 μm. It will be appreciated that the size of the through holes 2331 is directly related to the overall structural strength of the support 23 and the stability of the filling of the resilient material in the subsequent embodiments. In the present embodiment, in order to maintain the support 23 with good structural strength and stability of the filling elastic material in the subsequent embodiment, the first length L1 is approximately 20mm, and the second length L2 is approximately 150 μm. It should be noted that, in the embodiment of the present application, when the thickness of the supporting member 23 is about 0.15mm, it is verified through a plurality of folding simulation tests that the hole pitch of the through holes 2331 sequentially arranged along the X direction is 150 μm, the column pitch of the through holes 2331 sequentially arranged along the Y direction is 150 μm, and at the same time, when the first length L1 is 20mm and the second length L2 is 150 μm, the supporting member 23 has better supporting strength, and the folding effect of the display screen assembly 20 is better.
It will be appreciated that the cross-section of the through bore 2331 is generally rectangular, i.e., has a longer side and a shorter side. In the present embodiment, the longer side of the through hole 2331 is substantially parallel to the X-direction, and the shorter side of the through hole 2331 is substantially parallel to the Y-direction.
Of course, in other embodiments, the cross-section of the through-hole 2331 may be other shapes, for example, the cross-section of the through-hole 2331 may be shaped like one or more of a rectangle, an oval, a circle, a polygon, etc. Generally, the cross section of the through hole 2331 along the XY-plane generally has a relatively longer side and a relatively shorter side, and the relatively longer side is generally parallel to the X-direction and the relatively shorter side is generally parallel to the Y-direction.
It should be noted that, the position of the through hole 2331 of the supporting member 23 is in a hollow state, which is not beneficial to the uniform stress of the display screen 21. In the embodiment of the present application, the through hole 2331 is filled with an elastic material, so that the display screen 21 can be uniformly stressed. Specifically, the elastic material filled in the through hole 2331 may be silica gel, rubber or other flexible colloid material, so that the through hole 2331 may be completely filled, and the surface of the through hole 2331 is easy to process so that the surface of the through hole 2331 is flush with the surface of the folded portion 233. In other words, the elastic material is flush with the surface of the bottom wall 231 of the support 23 at the end position of the through hole 2331. Of course, in other embodiments, the through holes 2331 may be filled with a material having slight elasticity similar to foam, or the like.
It should be noted that the supporting member 23 may use a rigid spacer to enhance the structural strength of the entire display screen assembly 20. For example, the support 23 may be made of steel sheet. Of course, in other embodiments, the support 23 may be made of an alloy material, such as an aluminum alloy. The support 23 may be a sheet-like structure having a certain thickness. In the present embodiment, the thickness of the support 23 is about 0.15mm. Of course, in other embodiments, the support 23 may be selected with other thickness according to the size of the whole machine, the thickness requirement, and the folding requirement, for example, the thickness of the support 23 may be one of 0.08mm, 0.10mm, 0.15mm, 0.25mm, 0.28mm, etc.
It will be appreciated that when the thickness of the support 23 is in the range of 0.08-0.28mm, the support 23 provides better support for the display 21 and better improves the structural strength of the display assembly 20. In addition, when the supporting member 23 is a sheet structure with a smaller thickness, the overall structure thickness of the electronic device 100 can be further reduced, and the user experience is improved.
With continued reference to fig. 5, the display screen assembly 20 may also include a buffer 25. The buffer member 25 is disposed between the display screen 21 and the supporting member 23, and the buffer member 25 can effectively absorb impact from internal or external pressure of the whole machine, so as to avoid imprinting on the display surface of the display screen 21, and further influence normal display of the whole machine.
Specifically, the buffer member 25 is fully attached to one side of the display screen 21, which is close to the bottom wall 231 of the support member 23, that is, the buffer member 25 is attached to the entire surface of the display screen 21 and the attaching surface is flat, so that when the display screen 21 is impacted by pressure from the inside or the outside of the whole machine, the buffer member 25 can effectively absorb the impact, thereby avoiding the display screen 21 from being impacted by the pressure to generate display embossing and affecting the display effect. In other words, the buffer member 25 is provided on the side of the base film 211 near the bottom wall 231 of the support member 23, and is adhesively fixed to the bottom wall 231 by the second adhesive layer 60.
Further, the buffer member 25 may be made of a flexible material having a certain elasticity, and in this embodiment, the buffer member 25 is made of a high-modulus glue material, such as a glue material like polyurethane sealant. Of course, in other embodiments, the cushioning member 25 may be made of other materials, such as foam, a blend of one or more of the materials.
Referring to fig. 5 and 6 in combination, the side wall 232 of the support 23 generally includes a first side wall 2321, a second side wall 2322, and a third side wall 2323 connected in sequence. The first sidewall 2321 and the third sidewall 2323 are disposed opposite, and the second sidewall 2322 is disposed between the first sidewall 2321 and the third sidewall 2323. The first sidewall 2321, the second sidewall 2322, and the third sidewall 2323 are respectively connected with adjacent three sides of the bottom wall 231 in a bending manner.
Specifically, the bottom wall 231 may include a support portion 2311 and an inflection portion 2312 connected in a bent manner. The first side wall 2321, the second side wall 2322 and the third side wall 2323 are respectively connected with adjacent three sides of the supporting portion 2311 in a bending manner, and form the accommodating space 230 for accommodating the display screen 21. The inflection portion 2312 is disposed on a side of the support portion 2311 away from the sidewall 232, and can be used for mounting the IC chip 80 or other components of the electronic device 100, so as to improve the internal space utilization of the electronic device. Meanwhile, the IC chip 80 is provided at the reverse turn portion 2312 to enhance the impact resistance of the IC chip 80. The display panel 212 may be configured to be folded and extended to the reverse folded portion 2312 and connected to the IC chip 80. The support portion 2311 and the reverse folding portion 2312 are integrally formed, and an edge of the support portion 2311, to which the side wall 232 is not connected, is reverse folded toward a side of the support portion 2311, which is away from the side wall 232, to form the reverse folding portion 2312.
Wherein the folding portion 233 is formed at a middle region of the supporting portion 2311 and is bendable and foldable about the X-direction. The first and third sidewalls 2321 and 2323 are provided at opposite sides of the folded portion 233, and can be folded synchronously about the X direction as the folded portion 233 is folded. The first sidewall 2321 and the third sidewall 2323 are respectively provided with a avoidance groove 2320 located at opposite ends of the folded portion 233, that is, the region where the first sidewall 2321 and the third sidewall 2323 are respectively connected with the folded portion 233 is hollowed out to form the avoidance groove 2320, so as to reduce the internal stress of bending and folding of the support member 23.
It is appreciated that the second sidewall 2322 may correspond to a top region of the electronic device 100, the first sidewall 2321 and the third sidewall 2323 may correspond to side regions of the electronic device 100, respectively, and the inflection 2312 corresponds to a bottom region of the electronic device 100. Of course, in other embodiments, the support 23 may also have other corresponding relationships with the electronic device 100, and the corresponding relationships between the support 23 and the electronic device 100 are not intended to limit the scope of the present application.

The magnetic member 1221 may generate a magnetic force acting on the sidewall 232, and the magnetic force continuously acts on the sidewall 232 to exert an outward pulling force on the sidewall 232, thereby preventing the display screen assembly 20 from generating a crease or dent or arching phenomenon during the folding process.
Specifically, the support 23 may be made of a magnetic material, so that the magnetic member 1221 may attract the sidewall 232. Alternatively, the side wall 232 of the support 23 may be magnetized, thereby enabling the magnetic member 1221 to attract the side wall 232. Alternatively, a magnet may be provided on the side wall 232 of the support 23 to attract the side wall 232 by magnetic force with the magnetic member 1221. In this embodiment, the magnetic member 1221 may be a permanent magnet or an electromagnet.

The elastic member 1222 is disposed between the sidewall 232 and the side frame 122, and can generate elastic force acting on the sidewall 232. The spring force continues to act on the side walls 232 to exert an outward pulling force on the side walls 232, thereby avoiding creasing or dent or arching of the display screen assembly 20 during folding.
It is understood that the elastic member 1222 may be disposed between at least one of the first, second, and third sidewalls 2321, 2322, and the side frame 122 corresponding thereto.
It will be appreciated that the folding area of the display screen assembly 20 is creased or notched or arching in essence, as the display screen assembly 20 is folded, the edge areas of the folding screen assembly 20 shrink toward the middle area, forming creases or notches or arching over time. In this embodiment, the elastic member 1222 can apply continuous pulling force to the sidewall 232, so as to reduce the crease or dent. The elastic member 1222 may be a spring or foam.
