Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, in particular to an electronic equipment, a display screen assembly, a supporting assembly and a reinforcing plate. BACKGROUND

[0002] At present, with the development of electronic equipment technology, users have higher and higher requirements for electronic equipment with large size and easy to carry, therefore, electronic equipment with folding display screen has attracted widespread attention. Among them, the folding screen can be unfolded when in use to provide a larger display area, and switched to a folded state when not in use, which is convenient for users to carry.

[0003] The existing electronic equipment usually has a hole design on both sides of the rotating shaft for avoidance or connection and fixation. The hole is insufficient in supporting the display screen, which may cause problems such as bright spots and black spots, and cannot meet the normal use requirements. CONTENT OF THE UTILITY MODEL

[0004] The purpose of the present application is to provide an electronic equipment, a display screen assembly, a supporting assembly and a reinforcing plate, which can improve the situation of display screen bright spots and black spots.

[0005] In a first aspect of the present application, an electronic equipment is provided, comprising: a display screen, a supporting member, a reinforcing plate and a rotating shaft mechanism which are arranged in layers. The supporting member is arranged on the side away from the light-emitting surface of the display screen. The supporting member comprises: a bendable part, a first non-bendable part and a second non-bendable part. When the display screen is in a flat state, the bendable part is located between the first non-bendable part and the second non-bendable part. The bendable part is arranged opposite to the rotating shaft mechanism.

[0006] The bendable part comprises a first area, and the first area comprises a first hole. The rotating shaft mechanism comprises a rotating shaft door plate, and the rotating shaft door plate comprises a second area opposite to the first area. The second area comprises a second hole. The first area is opposite to the second area. The reinforcing plate comprises: a first part. The first part is arranged in layers between the first area and the second area, and the first part is used to cover the first hole and the second hole.

[0007] The first area of the supporting member has the first hole, so that the supporting ability of the first area to the display screen is poor. The second area of the rotating shaft door plate has the second hole, so that the supporting ability of the second area to the first area and the display screen is also poor. The first part of the reinforcing plate of the present application is arranged between the first area and the second area, so that the first area of the supporting member and the display screen can be supported by means of the reinforcing plate. Especially when the display screen is in a half-folded state or the display screen is subjected to extrusion, the supporting effect of the display screen provided by the first part of the reinforcing plate can improve the situation that the display screen in this part of the area has bright spots and black spots due to insufficient support of the display screen. In addition, the supporting effect of the display screen provided by the first part of the reinforcing plate can also improve the extrusion resistance and impact resistance of the electronic equipment.

[0008] In an optional implementation, the hinge mechanism includes two hinge door plates. The first part includes a first sub-region on the hinge door plates and a second sub-region between the two hinge door plates. The hinge mechanism further includes a hinge arc arm. The hinge arc arm is connected with the two hinge door plates. At least a part of the projection of the hinge arc arm on the reinforcing plate is located in the second sub-region. The hinge arc arm can rotate with the two hinge door plates, thereby driving the display screen to fold or unfold. The two first sub-regions of the first part on the two hinge door plates can cover the first opening and the second opening. The second sub-region of the first part between the two hinge door plates can cover at least a part of the hinge arc arm. When the electronic device falls in a hovering scenario, the impact between the bendable part and the hinge arc arm caused by the swing of the bendable part can be avoided, and the occurrence of display screen mura or bright spot defects can be avoided.

[0009] In an optional implementation, along the folding line of the display screen, the hinge mechanism includes opposite first and second ends. The first and second ends are arranged at the edges of the electronic device. The first part includes a first sub-part and a second sub-part. The first sub-part is arranged close to the first end, and the second sub-part is arranged close to the second end. In order to avoid or connect the fixing, along the folding line of the display screen, the part close to the first end and the part close to the second end of the hinge door plate are provided with a plurality of second openings. The first sub-part arranged close to the first end can shield the second openings close to the first end. The second sub-part arranged close to the second end can shield the second openings close to the second end. The reinforcing plate can shield a plurality of second openings, thereby improving the support provided by the reinforcing plate to the bendable part and the display screen.

[0010] In an optional implementation, the first part further includes a third sub-part. The third sub-part is arranged between the first sub-part and the second sub-part. The bendable part includes a third region, and the third region includes a third opening. The third sub-part is used to cover the third opening. By covering the third opening in the third region of the bendable part through the third sub-part, the support of the reinforcing plate to the bendable part is further improved.

[0011] In an optional implementation, the electronic device further includes a first middle frame and a second middle frame. The first middle frame is arranged opposite to the first non-bendable part, and the first middle frame can provide support to the first non-bendable part. The second middle frame is arranged opposite to the second non-bendable part. The first middle frame can provide support to the first non-bendable part.

[0012] The reinforcing plate comprises a second part connected with the first part. The second part comprises opposite first and second surfaces. The first surface of the second part is connected with the first non-bending part, and / or the second surface of the second part is connected with the first middle frame. The reinforcing plate is fixed to enable the reinforcing plate to be stably arranged between the support and the rotating shaft mechanism. When the display screen is bent, the first part is bent, and the first part can slide relative to the support. The rebound force in the bending is reduced, and the electronic device cannot be closed due to excessive bending stress of the reinforcing plate.

[0013] In an optional implementation, the reinforcing plate further comprises a third part. The third part is connected with the first part. When the display screen is in the flat state, the third part is located on the side of the first part away from the second part. The third part of the reinforcing plate can increase the friction between the reinforcing plate and the support or the second middle frame. The stress mutation of the reinforcing plate during the bending is prevented, and the bending deformation is out of sync. The width of the third part is smaller than the width of the first part. Then, the third part is facilitated to avoid other components in the electronic device.

[0014] In an optional implementation, the electronic device comprises a glue layer. The glue layer is arranged on the surface of the bendable part away from the display screen. The reinforcing plate comprises an avoiding hole, and the glue layer is arranged in the avoiding hole. The glue layer is avoided through the avoiding hole on the reinforcing plate. The bendable part on both sides of the reinforcing plate and the rotating shaft mechanism can be connected through the glue layer. In addition, the stress of the reinforcing plate during the bending is reduced after the avoiding hole is arranged on the reinforcing plate, and then the rebound force of the reinforcing plate during the bending is reduced, and the influence of the reinforcing plate on the bending of the electronic device is reduced.

[0015] In an optional implementation, the reinforcing plate comprises a lubricating layer and a supporting layer arranged in layers. The lubricating layer is arranged on the surface of the supporting layer facing or away from the display screen and connected with the supporting layer. The friction between the reinforcing plate and the support or the rotating shaft mechanism during the bending is reduced through the lubricating layer arranged on the surface of the supporting layer, so as to facilitate the bending of the reinforcing plate. The lubricating layer can also improve the wear resistance of the reinforcing plate.

[0016] In an optional implementation, the material of the lubricating layer comprises Teflon or polyethylene terephthalate (PET). Both Teflon coating film and PET film have a low friction coefficient, so that the friction between the reinforcing plate and the support or the rotating shaft mechanism is small when the reinforcing plate slides. Teflon has excellent wear resistance and corrosion resistance, so as to ensure the service life of the lubricating layer.

[0017] In an 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. The thickness of the lubricating layer is greater than or equal to 0.01mm, which can avoid the damage of the lubricating layer when the electronic device is bent, thereby ensuring the lubricating effect. The thickness of the lubricating layer is less than or equal to 0.1mm, which prevents the increase of the size of the electronic device due to the too large thickness of the lubricating layer.

[0018] In an optional embodiment, the material of the supporting layer includes a metal material. Exemplarily, the material of the supporting layer can be stainless steel, titanium alloy, etc. The metal material (such as stainless steel and titanium alloy material) has a large hardness, which can meet the required supporting capacity of the reinforcing plate.

[0019] In an optional embodiment, the thickness of the supporting layer is 0.01mm-0.1mm. Exemplarily, the thickness of the supporting layer can be 0.01mm, 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc. The thickness of the supporting layer is greater than or equal to 0.01mm, which can ensure the rigidity of the supporting layer, thereby ensuring the supporting capacity of the reinforcing plate to the supporting member and the display screen. The thickness of the supporting layer is less than or equal to 0.1mm, which avoids the increase of the stress of the reinforcing plate when it is bent due to the too large thickness of the supporting layer, thereby reducing the influence of the reinforcing plate on the bending of the electronic device. The thickness of the supporting layer is less than or equal to 0.1mm, which can prevent the increase of the size of the electronic device due to the too large thickness of the supporting layer.

For ease of illustration, the following embodiments are described by taking a foldable mobile phone as an example.

[0051] Referring to Figure 1 , the electronic device 100 can include a display screen assembly 10. The display screen assembly 10 includes a display screen 01. The display screen 01 can be a flexible display screen, which has the characteristics of strong flexibility and bendability, and can provide a new interaction mode based on the bendable characteristics for a user. The display panel of the display screen 01 can be, for example, any one of a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a quantum dot light emitting diode (QLED), and the like, which is not limited in the embodiments of the present application.

[0052] For ease of description of the following embodiments, with reference to Figure 1 , the XYZ coordinate system is established for the electronic device 100 in the unfolded state, the length direction of the electronic device 100 is defined as the X-axis direction, the width direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It can be understood that the coordinate system of the electronic device 100 can be flexibly set according to actual needs, which is not specifically limited herein.

[0053] In addition, referring to Figure 1 , the electronic device 100 includes a first middle frame 20, a second middle frame 30, and a rotating shaft mechanism 40 arranged 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 carry the display screen 01, so that the display screen 01 can be kept as flat as possible during use and protected.

[0054] In addition, other electronic elements such as a camera, earphone, receiver, key, battery, etc. can also be arranged on the first middle frame 20 and the second middle frame 30, and the present application does not limit the other electronic elements arranged on the first middle frame 20 and the second middle frame 30.

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

[0056] The above embodiments are illustrated by taking the electronic device 100 as a double-screen electronic device as an example. The electronic device 100 involved in the embodiments of the present application can also be a more-screen device, such as a three-screen folding, four-screen folding, etc. electronic device 100. The embodiments of the present application do not make specific limitations. Figure 1

[0057] Figure 1 The electronic device 100 shown in Figure 1 The display screen 01 in the unfolded state shown in

[0058] Alternatively, in some other embodiments of the present application, when the display screen 01 is in the unfolded state, the first non-foldable display part 12, the foldable display part 11, and the second non-foldable display part 13 can also be arranged in sequence along the Y-axis direction. In this way, the electronic device 100 can be folded in the vertical direction. When the display screen 01 is in the unfolded state, large-screen display can be realized to provide more abundant information for the user.

[0059] Referring to Figure 2 ( Figure 1 The structure schematic diagram of the electronic device 100 in the folded state), the inward folding state of the electronic device 100 is shown, that is, the electronic device 100 is folded towards the display screen 01 (such as Figure 1 ​In some embodiments of the present application, the electronic device 100 can be inwardly folded, i.e. the electronic device 100 is bent towards the side where the display screen 01 is located. When the electronic device 100 is inwardly folded, the first middle frame 20 and the second middle frame 30 can be close to each other, so that the first non-folded display part 12 (as shown in FIG. 1A) and the second non-folded display part 13 (as shown in FIG. 1A) can be close to each other. Figure 1 Figure 1

[0060] In some other embodiments of the present application, the electronic device 100 can also be outwardly folded, i.e. the electronic device 100 is bent away from the side where the display screen 01 is located. When the electronic device 100 is outwardly folded, the first non-folded display part 12 and the second non-folded display part 13 can be close to each other.

[0061] Referring to Figure 3 Figure 1 FIG. 1C is an exploded schematic view of the electronic device 100), the display screen assembly 10 can further include a support assembly 02. The support assembly 02 includes a support piece 21. The support piece 21 is arranged on the side of the display screen 01 opposite to the light-emitting surface L of the display screen 01. The display screen 01, the support piece 21 and the pivot mechanism 40 are arranged in layers. The support piece 21 is used to increase the structural strength of the display screen 01, and the support piece 21 can be folded together with the display screen 01. The support piece 21 can also be referred to as a bamboo book. The material of the bamboo book can be carbon fiber. Alternatively, the support piece 21 can also be a metal thin material, such as a stainless steel thin material, a titanium alloy thin material, a copper alloy thin material or an aluminum alloy thin material, etc. The support piece 21 can provide a supporting force for the display screen 01, which is conducive to ensuring the overall flatness of the display screen 01, and further conducive to ensuring the anti-extrusion performance of the electronic device 100. The support piece 21 can include a foldable part 211, a first non-foldable part 212 and a second non-foldable part 213. When the display screen 01 is in the unfolded state, the foldable part 211 is located between the first non-foldable part 212 and the second non-foldable part 213. The foldable part 211 is arranged opposite to the pivot mechanism 40. The pivot mechanism 40 can drive the foldable part 211 and the display screen 01 to be folded or unfolded, so as to switch the display screen 01 between the unfolded state and the folded state.

[0062] Referring to Figure 4 Figure 3 FIG. 1D is an enlarged view of the electronic device 100 at A shown in FIG. 1C), in order to facilitate the folding of the support piece 21 (as shown in FIG. 1C), a first opening 2112 is formed on a first region 2111 (as shown in the dashed line part in the figure) of the foldable part 211. In this way, the rebound force of the support piece 21 when the electronic device 100 is folded can be reduced, and the folding of the electronic device 100 is facilitated. Figure 3

[0063] Referring to Figure 3 ​​​​​The hinge mechanism 40 may include a hinge door panel 41. For example, the hinge mechanism 40 may include two hinge door panels 41, which are configured to move toward 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 hinge door panels 41 may be rotatably connected by a hinge, a hinge, or the like, which is not specifically limited in this application.

[0064] See Figure 5 ( Figure 3 The electronic device 100 is shown in the enlarged view at B), the hinge door panel 41 includes a second area 411 (shown as a dotted line portion in the figure). Along the Z-axis direction, the second area 411 and the first area 2111 (shown as a dotted line portion in the figure) are connected. Figure 4 The second opening 412 is usually designed on the second area 411 of the hinge door panel 41. The second opening 412 is used to avoid or connect and fix other components (such as a hinge, a hinge, etc., not shown in the figure). Since the second opening 412 cannot be used to connect the support member 21 (such as Figure 3 As shown in FIG. 4 ), the second region 411 provides support to the bendable portion 211 of the support member 21 (as shown in FIG. Figure 3 As shown) and display screen 01 (as shown Figure 3 The support capacity of the Figure 4 Furthermore, since the first area 2111 of the bendable portion 211 has the first opening 2112 , the supporting performance of the first area 2111 on the display screen 01 is limited.

[0065] In such Figure 5 The second area 411 shown is Figure 4 The first area 2111 shown is not sufficiently supported, and the first area 2111 is not sufficiently supported on the display screen 01 (e.g. Figure 3 If the support (as shown) is insufficient, the second opening 412's ability to squeeze the display screen 01 is significantly lower than at other locations. When the display screen 01 is half-folded or squeezed, the display screen 01 located on the side of the first area 2111 may exhibit bright spots and dark spots, failing to meet normal usage requirements. In the folded area of ​​the display screen 01, the number of bright spots and dark spots can account for over 60% of the total number of bright spots and dark spots.

[0066] To solve the above problems, see Figure 3 The supporting assembly 02 of the electronic device 100 provided in the embodiment of the present application may further include a reinforcing plate 22. Figure 6 ( Figure 1As shown in the cross-sectional view of the electronic device 100 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 from 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. 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 reinforcing plate 22 can support the first region 2111 of the support member 21 and the display screen 01. In particular, when the display screen 01 is in a half-folded state or is squeezed, the problem of bright spots or dark spots appearing in the portion of the display screen 01 due to insufficient support for the display screen 01 can be improved. Furthermore, the support provided by the first portion 221 of the reinforcing plate 22 to the display screen 01 can also improve the anti-extrusion and anti-impact capabilities of the electronic device 100 .

[0067] In the embodiment of the present application, the bending line M (eg Figure 1 When the tip extrusion capacity test is performed on the areas on both sides of the bending line M of the display screen 01 of the electronic device 100 (i.e., the area along the Z-axis direction where the display screen 01 is located directly above the rotating shaft door panel 41), the tip extrusion capacity of the electronic device 100 provided in the embodiment of the present application can be increased from 1.8kg to 5.6kg. The tip extrusion capacity is improved by 211%. When the straight-end extrusion capacity test is performed on the areas on both sides of the bending line M of the display screen 01 of the electronic device 100, the straight-end extrusion capacity of the electronic device 100 provided in the embodiment of the present application can be increased from 1.755kg to 4.5kg. The straight-end extrusion capacity is improved by 139%.

[0068] As another example, the second region 411 may also have features such as steps or screws (not shown). These features render the second region 411 a non-complete planar structure. Consequently, the second region 411's support for the first region 2111 and the display screen 01 is discontinuous. 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 problem of bright spots and dark spots on the display screen 01.

[0069] See Figure 6The hinge mechanism 40 further comprises a gap G between the two hinge door plates 41. The second area 411 can comprise at least part of the gap G. The support ability of the support member 21 and the display screen 01 at the gap G is also poor. The reinforcing plate 22 can cover at least part of the gap G and support the support member 21 and the display screen 01. The support effect of the reinforcing plate 22 on the display screen 01 is further improved, and the display screen 01 bright spot and black spot defects are improved.

[0070] Referring to Figure 7 (Sectional view of the electronic device 100 in the half-folded state), the first part 221 comprises two first sub-areas 2211 on the two hinge door plates 41 and a second sub-area 2212 between the two hinge door plates 41. The hinge mechanism 40 further comprises a hinge arc arm 42. The hinge arc arm 42 is connected with the two hinge door plates 41. At least part of the projection of the hinge arc arm 42 on the reinforcing plate 22 is located in the second sub-area 2212. The hinge arc arm 42 can rotate in cooperation with the two hinge door plates 41, thereby driving the display screen 01 to fold or unfold. The two first sub-areas 2211 of the first part 221 on the two hinge door plates 41 can cover the first opening 2112 and the second opening 412. The second sub-area 2212 of the first part 221 between the two hinge door plates 41 can cover at least part of the hinge arc arm 42. When the electronic device 100 falls in the hovering scenario, the impact of the bendable part 211 on the hinge arc arm 42 after the swing of the bendable part 211 is avoided, and the occurrence of the display screen 01 black spot or bright spot defects is avoided.

[0071] In the hovering scenario drop test of the electronic device 100 provided by the embodiment of the present application, the black spot or bright spot defect caused by the swing of the bendable part 211 and the impact of the bendable part 211 on the hinge arc arm 42 is avoided when the electronic device 100 falls from 1.2m hovering. The black spot or bright spot defect caused by the impact of the bendable part 211 on the hinge arc arm 42 is avoided when the electronic device 100 falls from 1.5m hovering. The hovering scenario drop performance of the electronic device 100 is greatly improved.

[0072] Referring to Figure 8 (Partial schematic view of the electronic device 100 after removing the display screen 01 and the support member 21), along the folding line M (as Figure 3 indicated) of the display screen 01 (as Figure 1As shown), the hinge mechanism 40 includes a first end a and a second end b relative to each other. The first end a and the second end b are arranged 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 arranged close to the first end a, and the second sub-part 2214 is arranged close to the second end b. In order to avoid or connect and fix, along the bending line M of the display screen 01, the part of the hinge mechanism 40 close to the first end a and the part close to the second end b will have more second openings 412. The first sub-part 2213 is arranged close to the first end a, and can block the second opening 412 close to the first end a. The second sub-part 2214 is arranged close to the second end b, and can block the second opening 412 close to the second end b. The reinforcement plate 22 can block more second openings 412, thereby improving the support of the bendable portion 211 (such as Figure 3 As shown) and the support provided by the display screen 01.

[0073] See 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-shaped opening.

[0074] See Figure 9 (Partial schematic diagram of another electronic device 100 after removing the display screen 01 and the support member 21), the first portion 221 also includes a third sub-portion 2215. The third sub-portion 2215 is arranged between the first sub-portion 2213 and the second sub-portion 2214. The third sub-portion 2215 is used to cover the third opening 2114 (such as Figure 4 The bendable portion 211 is covered by the third sub-portion 2215 (as shown). Figure 4 The third area 2113 (as shown) Figure 4 The third opening 2114 in the reinforcing plate 22 further enhances the supporting effect of the bendable portion 211.

[0075] The above embodiment Figure 9 The illustration shows an example in which the third subsection 2215 is connected to the first subsection 2213 and the second subsection 2214, so that the reinforcing plate 22 extends from the first end a to the second end b. In other embodiments of the present application, the third subsection 2215 may be spaced apart from the first subsection 2213 and the second subsection 2214. The number of third subsections 2215 may be one or more, and this is not specifically limited in the present embodiment.

[0076] See Figure 10 (like Figure 1As shown in the cross-sectional view of the electronic device 100 along the P1-P2 direction), the reinforcing plate 22 includes a second portion 222 connected with the first portion 221. The second portion 222 includes opposite first and second surfaces S1 and S2. The first surface S1 of the second portion 222 is connected with the first non-bending portion 212. The reinforcing plate 22 is fixed so as to be stably arranged between the support 21 and the hinge mechanism 40. Referring to Figure 11 (Structure schematic diagram of the display screen assembly 10 in the folded state), when the display screen 01 is bent, the first portion 221 is bent. During the bending process, the first portion 221 can slide relative to the support 21. When the electronic device 100 is bent, the part of the reinforcing plate 22 between the bendable portion 211 and the hinge mechanism 40 can slide relative to the support 21, so as to reduce the rebound force in the bending process and prevent the electronic device 100 from being unable to close due to excessive bending stress of the reinforcing plate 22.

[0077] The above embodiments are Figure 10 and Figure 11 As shown, the second portion 222 of the reinforcing plate 22 is connected with the first non-bending portion 212. In other embodiments of the present application, the second portion 222 of the reinforcing plate 22 can also be connected with the second non-bending portion 213. The embodiments of the present application are not limited in particular.

[0078] As an example, referring to Figure 10 , the first surface S1 and the first non-bending portion 212 can be fixed by the adhesive 50. The adhesive 50 can include at least one of double-sided tape, hot melt adhesive, back adhesive, thermosetting adhesive, shadowless adhesive, etc. The adhesive 50 composed of any one or more of the above adhesives has good adhesion, so as to improve the connection stability of the second portion 222 and the first non-bending portion 212.

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

[0080] Referring to Figure 11After the second portion 222 of the reinforcing plate 22 is bonded to the support member 21, a colloid (not shown in the figure) may also be applied to the second surface S2 of the second portion 222 facing away from the support member 21, and a separation paper (not shown in the figure) may be applied to the surface of the colloid facing away from the second portion 222 to form the display screen assembly 10. When the display screen assembly 10 is connected to the hinge mechanism 40, the separation paper may be removed, and the colloid may be applied to the first middle frame 20 (e.g., Figure 3 As shown), forming Figure 12 (like Figure 1 The electronic device 100 is shown as a cross-sectional view of another electronic device 100 along the P1-P2 direction. The first surface S1 of the second portion 222 of the electronic device 100 is connected to the first non-bending portion 212, and the second surface S2 of the second portion 222 is connected to the first middle frame 20. This allows the reinforcing plate 22 to be fixed on both sides, further improving the fixing reliability of the reinforcing plate 22.

[0081] In some other embodiments, see Figure 13 (like Figure 1 In the cross-sectional view of another electronic device 100 along the direction P1 - P2 , the second surface S2 of the second portion 222 is connected to the first middle frame 20 to fix the reinforcing plate 22 .

[0082] For example, the second portion 222 and the first middle frame 20 may be fixed by means of a colloid 50 or by screws (not shown in the figure), which is not specifically limited in the present application.

[0083] The above embodiment Figure 12 or Figure 13 The figures shown are all examples of the connection between the second portion 222 of the reinforcing plate 22 and the first middle frame 20. In other embodiments of the present application, the second portion 222 of the reinforcing plate 22 may also be connected to the second middle frame 30. This embodiment of the present application is not specifically limited.

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

[0085] See Figure 15(Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the width w1 of the third part 223 is less than the width w2 of the first part 221. This facilitates the third part 223 to avoid other components (such as the mainboard, the battery, etc.) in the electronic device 100.

[0086] The above embodiments are all based on the second area 411 (as shown in Figure 6 ) which can include at least part of the gap G (as shown in Figure 6 ). The above description is based on the example that the second area 411 is covered by the reinforcing plate 22. In other embodiments of the present application, referring to Figure 16 , the second area 411 can not include the gap G, and the reinforcing plate 22 only covers the second opening 412 and the peripheral area. The present application is not limited in this embodiment.

[0087] Referring to Figure 17 (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to Figure 18 (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to Figure 1 (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to

[0088] (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to Figure 18 (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to

[0089] (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to

[0090] (Further partial view of the electronic device 100 after removing the display screen 01 and the support 21), the reinforcing plate 22 includes the avoiding hole 224. Referring to Figure 18The reinforcing plate 22 may include a laminated lubricating layer 225 and a supporting layer 226. The lubricating layer 225 is disposed on the surface of the supporting layer 226 facing toward 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 friction between the reinforcing plate 22 and the support member 21 or the rotating shaft mechanism 40 during bending, thereby facilitating bending of the reinforcing plate 22. The lubricating layer 225 can also improve the wear resistance of the reinforcing plate 22.

[0091] See Figure 18 Along the Z-axis direction, the avoidance hole 224 can penetrate the support layer 226 and the lubricating layer 225 to ensure that the adhesive layer 60 can be connected to the bendable portion 211 and the rotating shaft mechanism 40 on both sides of the reinforcing plate 22.

[0092] The above embodiment Figure 18 The illustration shows an example in which the lubricating layer 225 is provided on both sides of the support layer 226, facing or facing away from the display screen 01. In other embodiments of the present application, the lubricating layer 225 may be provided only on the side of the support layer 226 facing the display screen 01. Alternatively, the lubricating layer 225 may be provided only on the side of the support layer 226 facing away from the display screen 01.

[0093] For example, Figure 18 The lubricating layer 225 can be made of Teflon or polyethylene terephthalate (PET). Both Teflon and PET films have a low coefficient of friction, ensuring minimal friction between the reinforcing plate 22 and the support member 21 or the rotating shaft mechanism 40 when the reinforcing plate 22 slides. Teflon also offers excellent wear and corrosion resistance, ensuring a long service life for the lubricating layer 225.

[0094] like Figure 19 ( Figure 18 The thickness h1 of the lubricating layer 225 shown in the enlarged view at C can be 0.01mm-0.1mm. For example, the thickness h1 of the lubricating layer 225 can be 0.01mm, 0.02mm, 0.04mm, 0.06mm, 0.08mm, 0.1mm, etc. The thickness h1 of the lubricating layer 225 is greater than or equal to 0.01mm, which can prevent the lubricating layer 225 from being damaged when the electronic device 100 is bent, thereby ensuring the lubrication effect. The thickness h1 of the lubricating layer 225 is less than or equal to 0.1mm, which prevents the size of the electronic device 100 from being increased due to the excessive thickness h1 of the lubricating layer 225.

[0095] For example, Figure 19The material of the support layer 226 shown includes a metal material. For example, the material of the support layer 226 can be stainless steel, titanium alloy, etc. Metal materials (such as stainless steel and titanium alloy materials) are relatively hard and can meet the support capacity required by the reinforcement plate 22.

[0096] like Figure 19 The thickness h2 of the support layer 226 shown 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. The thickness h2 of the support layer 226 is greater than or equal to 0.01mm, which can ensure the rigidity of the support layer 226 and further ensure that the reinforcement plate 22 can support the support member 21 (such as Figure 3 As shown) and display screen 01 (as shown Figure 3 The thickness h2 of the support layer 226 is less than or equal to 0.1 mm, so as to avoid the stress of the reinforcing plate 22 being increased when the reinforcing plate 22 is bent due to the thickness of the support layer 226 being too large. Figure 3 The thickness of the support layer 226 is less than or equal to 0.1 mm, which can prevent the size of the electronic device 100 from increasing due to the thickness h2 of the support layer 226 being too large.

[0097] The present application provides an electronic device, a display screen assembly, a support assembly and a reinforcement plate. The electronic device includes: a stacked display screen assembly and a hinge mechanism. The display screen assembly includes: a display screen and a support assembly.

By providing a reinforcement plate, support is provided for the display screen to improve the situation where the display screen has bright spots and black spots in this area due to insufficient support of the display screen. The first part includes: two first sub-areas located on the two pivot door panels, and a second sub-area located between the two pivot door panels. The pivot mechanism also includes a pivot arc arm, which is connected to the two pivot door panels, and at least a portion of the projection of the pivot arc arm on the reinforcement plate is located in the second sub-area. The second sub-area prevents the bendable portion from colliding with the pivot arc arm, which may cause black spots or bright spots on the display screen. The reinforcement 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 middle frame, and the second part is connected to the first middle frame. The reinforcement plate is then fixed so that the reinforcement plate can be stably arranged between the support member and the pivot mechanism.
