Description

Technical Field

[0001] The present application relates to the technical field of foldable electronic products, and in particular to a protective device and an electronic device. Background Art

[0002] The foldable electronic device has a rotating shaft and a bendable screen, and the rotating shaft drives the screen to fold or unfold. In order to protect the screen, the foldable electronic device also includes a protective device. The protective device covers the edge of the part of the screen that is arranged opposite to the rotating shaft.

[0003] However, there is a gap between the protective device and the screen in the direction perpendicular to the screen. During the use of foldable electronic devices, foreign matter such as sweat, oil droplets, water vapor or dust may enter the interior of the foldable electronic device through the gap, corrode the edge of the screen, and cause problems such as internal film peeling or bending noise on the screen, which seriously affects the reliability of the electronic device. Utility Model Content

[0004] The embodiments of the present application provide a protective device and an electronic device, which are used to reduce the gap between the protective device and the screen and improve the reliability of the electronic device.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an electronic device is provided, which includes a screen, a rotating shaft and a protective device. The screen includes a first non-bending portion, a second non-bending portion and a bending portion, and the bending portion is located between the first non-bending portion and the second non-bending portion. The rotating shaft is arranged on the back of the bending portion. The protective device includes a first connecting portion, a second connecting portion and a blocking portion. The first connecting portion is connected to the rotating shaft, and along the axial direction of the rotating shaft, the first connecting portion is located on one side of the bending portion. The second connecting portion is connected to the first connecting portion; at least part of the second connecting portion is located on the front side of the bending portion, and there is a gap between the second connecting portion and the bending portion. The blocking portion is connected to the second connecting portion and is located in the gap.

[0007] In the embodiment of the present application, the first connection part is connected to the rotating shaft, so that the position of the protective device is fixed, and the protective device is not easy to move during the folding or unfolding of the electronic device, thereby ensuring the stability of the protective device. At least part of the second connection part of the protective device is located on the front of the bending part, and along the axial direction of the rotating shaft, the first connection part of the protective device is located on one side of the bending part. The first connection part and the second connection part can block impurities such as sweat, oil droplets, water vapor or dust, and prevent impurities such as sweat, oil droplets, water vapor or dust from entering the electronic device and damaging the screen.

[0008] Although there is a gap between the part of the second connection part located on the front side of the bending part and the bending part, the blocking part is located in the gap. In this way, no matter the electronic device is in the unfolded state, the intermediate state or the closed state, the maximum distance from the blocking part to the bending part can be smaller than the maximum distance from the second connection part to the bending part, and the blocking part can even completely close the gap. The gap between the protective device and the screen can be smaller or even 0, so that impurities such as sweat, oil droplets, water vapor or dust are not easy to enter the electronic device through the gap between the second connection part and the screen, thereby improving the problem that impurities such as sweat, oil droplets, water vapor or dust enter the electronic device, corrode the edge of the screen, cause the screen film layer to peel off or bend abnormally, etc., improve the reliability of the electronic device, and help to extend the service life of the electronic device.

[0009] In some embodiments, the angle between the blocking portion and the second connecting portion is greater than 0 degrees and less than or equal to 90 degrees.

[0010] In some embodiments, the blocking portion includes a first boundary away from the second connecting portion, and the distances from different points on the first boundary to the bent portion are the same. In this way, the minimum distances from different positions of the blocking portion to the bent portion are the same, and different positions of the blocking portion have the same blocking effect on impurities such as sweat, oil droplets, water vapor or dust, which is conducive to improving the overall blocking ability of the blocking portion to impurities such as sweat, oil droplets, water vapor or dust, and further protecting the screen.

[0011] In some embodiments, the end of the blocking portion away from the second connecting portion abuts against the front side of the bent portion. In this way, the blocking portion is in contact with the bent portion, and there is no gap between the blocking portion and the bent portion. The blocking portion can effectively block impurities such as sweat, oil droplets, water vapor or dust, thereby preventing impurities such as sweat, oil droplets, water vapor or dust from damaging the screen.

[0012] In some embodiments, the electronic device includes two protective devices, and the bent portion is located between the first connecting portions of the two protective devices in the axial direction of the rotating shaft. In this way, both ends of the bent portion in the axial direction of the rotating shaft can be protected by a protective device respectively, so that both ends of the bent portion in the axial direction of the rotating shaft are not easily corroded by impurities such as sweat, oil droplets, water vapor or dust.

[0013] In some embodiments, in the axial direction of the rotating shaft, the second connecting portion includes a first edge and a second edge, the first edge is closer to the first connecting portion than the second edge, and the blocking portion is located between the first edge and the second edge.

[0014] In this way, the projection of the blocking part on the screen is located inside the projection of the second connecting part on the screen. Except for the part of the screen blocked by the second connecting part, the blocking part will not block other parts of the screen. The area of ​​the part of the screen blocked by the protective device is small, and the protective device is not likely to affect the normal display of the screen.

[0015] In some embodiments, the second connecting portion is arched, and the end of the blocking portion connected to the second connecting portion is arc-shaped. In this way, the contact area between the blocking portion and the second connecting portion can be larger, and the connection stability between the blocking portion and the second connecting portion can be better.

[0016] In some embodiments, the second connection part and the blocking part are an integrated structure. In this way, during the preparation of the protective device, the second connection part and the blocking part can be formed in one piece, which is conducive to simplifying the preparation steps of the protective device and reducing the preparation cost. At the same time, the connection stability between the second connection part and the blocking part can be better, and the structural stability of the protective device can be better.

[0017] In some embodiments, the thickness of the blocking portion is less than or equal to 0.5 mm. In this case, the thickness of the blocking portion is small, the strength of the blocking portion can be weak, and the blocking portion is not easy to affect the bending of the second connecting portion, nor is it easy to squeeze the screen.

[0018] In some embodiments, the protective device further includes a third connecting portion, the third connecting portion includes a first sub-portion and a second sub-portion connected to each other, the first sub-portion extends in a direction perpendicular to the screen, and the second sub-portion extends in a direction parallel to the screen; the first sub-portion is connected to the first connecting portion, and the second sub-portion is connected to the second connecting portion. The second connecting portion has a groove on its surface facing the third connecting portion, and the second sub-portion extends into the groove.

[0019] The first sub-section extends in a direction perpendicular to the screen, and the first sub-section is connected to the first connecting section. The contact area between the first sub-section and the first connecting section can be large, and the connection stability between the first sub-section and the first connecting section is good. The second sub-section extends in a direction parallel to the screen, and the second sub-section extends into the groove of the second connecting section. The contact area between the second sub-section and the second connecting section can also be large, and the connection between the second sub-section and the second connecting section can be relatively stable. In this way, the third connecting section can be relatively stably connected to the first connecting section and the second connecting section, so that the overall stability of the protective device is better.

[0020] In some embodiments, the electronic device further includes a protective layer covering a side of the screen.

[0021] In the embodiment of the present application, a protective layer is also provided on the side of the screen while providing the protective device. In this way, even if impurities such as sweat, oil droplets, water vapor or dust enter the interior of the electronic device through the gap between the blocking portion and the bending portion, the protective layer can separate the impurities such as sweat, oil droplets, water vapor or dust from the side of the screen, further improving the problem that impurities such as sweat, oil droplets, water vapor or dust corrode the screen and affect the screen display, and damage the adhesive layer to cause the separation of multiple film layers inside the screen or abnormal bending and noise.

[0022] In some embodiments, the protective layer includes at least one of a fluorinated liquid coating, a glue coating, and an ink layer. In this way, on the one hand, the fluorinated liquid coating, the glue coating, and the ink layer have better ability to block grease and water vapor, which is conducive to improving the ability of the protective layer to block impurities such as sweat, oil droplets, water vapor or dust. On the other hand, the fluorinated liquid, the glue, and the ink are all fluid, and the uniformity of the protective layer formed by the fluorinated liquid, the glue, and the ink can be better, and the protective layer can evenly cover the side of the screen, thereby better protecting the side of the screen.

[0023] In a second aspect, a protective device is provided, which is applied to an electronic device. The electronic device includes a screen and a hinge. The screen includes a first non-bending portion, a second non-bending portion and a bending portion. The bending portion is located between the first non-bending portion and the second non-bending portion. The hinge is arranged on the back side of the bending portion.

[0024] The protective device includes a first connecting portion, a second connecting portion and a blocking portion. The first connecting portion is connected to the rotating shaft, and along the axial direction of the rotating shaft, the first connecting portion is located at one side of the bending portion. The second connecting portion is connected to the first connecting portion; at least part of the second connecting portion is located on the front side of the bending portion, and there is a gap between the second connecting portion and the bending portion. The blocking portion is connected to the second connecting portion and is located in the gap.

[0025] In some embodiments, the angle between the blocking portion and the second connecting portion is greater than 0 degrees and less than or equal to 90 degrees.

[0026] In some embodiments, in the axial direction of the rotating shaft, the second connecting portion includes a first edge and a second edge, the first edge is closer to the first connecting portion than the second edge, and the blocking portion is located between the first edge and the second edge.

[0027] In some embodiments, the second connecting portion is arched, and one end of the blocking portion connected to the second connecting portion is arc-shaped.

[0028] In some embodiments, the second connecting portion and the blocking portion are an integrated structure.

[0029] In some embodiments, the thickness of the barrier portion is less than or equal to 0.5 mm.

[0030] In some embodiments, the third connecting portion includes a first sub-portion and a second sub-portion connected to each other, the first sub-portion extending in a direction perpendicular to the screen, and the second sub-portion extending in a direction parallel to the screen; the first sub-portion is connected to the first connecting portion, and the second sub-portion is connected to the second connecting portion; the second connecting portion has a groove on the surface facing the third connecting portion, and the second sub-portion extends into the groove.

[0031] Among them, the technical effects brought about by any design method in the second aspect can refer to the technical effects brought about by the corresponding design method in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0047] In the following, in the embodiments of the present application, the terms "first", "second", etc. are only used for convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "plurality" means two or more.

[0048] In the embodiments of the present application, "upper", "lower", "left" and "right" are not limited to being defined relative to the positions of the components schematically placed in the drawings. It should be understood that these directional terms may be relative concepts. They are used for relative description and clarification, and may change accordingly according to the changes in the positions of the components in the drawings.

[0049] In the embodiments of the present application, unless the context requires otherwise, throughout the specification and claims, the term "including" is interpreted as an open, inclusive meaning, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "exemplarily" or "some examples" and the like are intended to indicate that specific features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the specific features, structures, materials or characteristics described may be included in any one or more embodiments or examples in any appropriate manner.

[0050] An embodiment of the present application provides an electronic device. The electronic device may be any electronic device having a foldable screen and capable of changing the unfolding or folding state of the foldable screen and the electronic device itself.

[0051] Under different usage requirements, the electronic device can be unfolded to a flat state, folded to a closed state, or in an intermediate state between the flat state and the closed state. It is understandable that the intermediate state does not have only one state, and can be any one or more states between the flat state and the closed state.

[0052] For example, the electronic device may include but is not limited to a mobile phone, a tablet computer, a laptop computer, an e-book reader, a camera, a wearable device, a home electronic device, etc. For ease of understanding, in each embodiment of the present application, the electronic device is described by taking a mobile phone as an example.

[0053] Figure 1 Schematic diagram of the electronic device 100 provided in the embodiment of the present application. Figure 1 As shown, the electronic device 100 includes a screen 10 and a hinge 20 .

[0054] The screen 10 is used to display information such as images or videos. The screen 10 has a front side S1 and a back side S2, wherein the front side S1 is used to display information such as images or videos, while the back side S2 cannot display information such as images or videos.

[0055] To display information such as images or videos, the screen 10 may include a flexible display panel. Exemplarily, the flexible display panel may be an organic light-emitting diode (OLED) panel, a micro organic light-emitting diode (micro organic light-emitting diode) panel, a quantum dot light emitting diode (QLED) panel, etc.

[0056] In order to protect the flexible display panel, the screen may further include a covering layer and a supporting layer, wherein the covering layer may be located on the display side (ie, the light emitting side) of the flexible display panel, and the supporting layer may be located on the non-display side of the flexible display panel.

[0057] The covering layer and the supporting layer may be a single-layer structure or a multi-layer structure. When the covering layer is a single-layer structure, the material of the covering layer may include polyimide (PI), polyethylene terephthalate (PET), thermoplastic urethane (TPU), etc. When the supporting layer is a single-layer structure, the material of the supporting layer may include stainless steel (SUS), titanium, carbon fiber, etc.

[0058] In the case where the covering layer and the supporting layer are multi-layer structures, the materials and functions of the multiple film layers in the covering layer and the supporting layer are not limited in the embodiments of the present application and can be set according to actual needs.

[0059] The screen may further include an adhesive layer, which may be located between the flexible display panel and the cover layer to connect the flexible display panel and the cover layer, and the adhesive layer may also be located between the flexible display panel and the support layer to connect the flexible display panel and the support layer. Of course, in the case where the cover layer and the support layer are multi-layer structures, the adhesive layer may also be located between multiple film layers of the cover layer and between multiple film layers of the support layer.

[0060] For example, the material of the adhesive layer may include optical clear adhesive (OCA). In this case, the adhesive layer is a transparent material, and the adhesive layer will not affect the light emission of the flexible display panel.

[0061] It can be understood that the film layer included in the screen 10 in the embodiment of the present application is not limited to the above example, and the film layer included in the screen 10 can be designed according to actual needs.

[0062] Continue reading Figure 1 The screen 10 may include a first non-bending portion A1, a second non-bending portion A2 and a bending portion A3. The bending portion A3 is located between the first non-bending portion A1 and the second non-bending portion A2. The bending portion A3 connects the first non-bending portion A1 and the second non-bending portion A2.

[0063] When the electronic device 100 is in the unfolded state, the first non-bending portion A1, the second non-bending portion A2 and the bending portion A3 are all in a straight state. When the electronic device 100 is in the folded state or the intermediate state, the bending portion A3 is bent and deformed, while the first non-bending portion A1 and the second non-bending portion A2 remain straight.

[0064] It is understandable that the screen 10 provided in the embodiment of the present application may have not only one bending portion A3 but also multiple bending portions A3. When the screen 10 has multiple bending portions A3, the two non-bending portions on both sides of any bending portion A3 may be referred to as the first non-bending portion A1 and the second non-bending portion A2.

[0065] Continue reading Figure 1 The rotating shaft 20 is disposed on the back of the bending portion A3. The back of the bending portion A3 is also the portion of the back side S2 of the screen corresponding to the bending portion A3. Exemplarily, the rotating shaft 20 can be connected to the bending portion A3 to drive the bending portion A3 to bend or unfold.

[0066] like Figure 1 As shown, the rotating shaft 20 may include a first door panel 21 and a second door panel 22, and the first door panel 21 and the second door panel 22 may be bonded to the bending portion A3. During the folding process of the screen 10, the first door panel 21 and the second door panel 22 may protect the screen 10. Of course, in some possible examples, the rotating shaft 20 may also include a third door panel, which is located between the first door panel 21 and the second door panel 22 and is used to support the screen 10.

[0067] In some embodiments, the electronic device 100 may further include a first middle frame 30 and a second middle frame 40. The first middle frame 30 and the second middle frame 40 are both located on the side of the screen 10 that is away from the display surface S1. The hinge 20 is located between the first middle frame 30 and the second middle frame 40, and connects the first middle frame 30 and the second middle frame 40. In the case where the hinge 20 includes a first door panel 21 and a second door panel 22, the first door panel 21 may be connected to the first middle frame 30, and the second door panel 22 may be connected to the second middle frame 40, or the first door panel 21 may be connected to the second middle frame 40, and the second door panel 22 may be connected to the first middle frame 30.

[0068] The first middle frame 30 can also be connected to the first non-bending portion A1, and the second middle frame 40 can also be connected to the second non-bending portion A2. During the folding and unfolding process of the electronic device 100, the rotating shaft 20 can drive the first middle frame 30 and the second middle frame 40 to move, the first middle frame 30 drives the first non-bending portion A1 to move, and the second middle frame 40 drives the second non-bending portion A2 to move. During the folding and unfolding process of the electronic device 100, the first middle frame 30 can support the first non-bending portion A1, and the second middle frame 40 can support the second non-bending portion A2, so that the first non-bending portion A1 and the second non-bending portion A2 remain in a straight state.

[0069] In some embodiments, Figure 1As shown, the electronic device 100 may further include a first decorative member 50 and a second decorative member 60. The first decorative member 50 is arranged around the edge of the first non-bending portion A1, and at least a portion of the first decorative member 50 is located on the front of the first non-bending portion A1, and the first decorative member 50 is used to protect the first non-bending portion A1. The second decorative member 60 is arranged around the edge of the second non-bending portion A2, and at least a portion of the second decorative member 60 may be located on the front of the second non-bending portion A2, and the second decorative member 60 is used to protect the second non-bending portion A2.

[0070] In order to prevent the first and second decorative members 50 and 60 from affecting the bending of the bending portion A3, the first and second decorative members 50 and 60 do not cover the edge of the bending portion A3. At this time, in order to protect the edge of the bending portion A3, the electronic device 100 may further include a protective device.

[0071] Figure 2 FIG. 8 is a schematic diagram showing the structure of a protective device 70 ′. Figure 2 As shown, the protection device 70 ′ includes a first connection portion 71 ′ and a second connection portion 72 ′ connected to each other, and the second connection portion 72 ′ is located at one side of the first connection portion 71 ′.

[0072] Figure 3 is a schematic diagram of a partial structure of the electronic device 100 when it is in an unfolded state, Figure 4 FIG. 1 is a schematic diagram of a partial structure of the electronic device 100 when it is in an intermediate state. Figure 3 and Figure 4 As shown, when the protective device 70' is applied to the electronic device 100, along the axial direction X of the rotating shaft 20, the first connection portion 71' of the protective device 70' is located on one side of the bent portion A3, and at least part of the second connection portion 72' of the protective device 70' is located on the front of the screen 10. Whether the electronic device is in the unfolded state, the intermediate state or the closed state, the protective device 70' can protect the edge of the bent portion A3.

[0073] Figure 5 It is a partial cross-sectional diagram of an electronic device. Figure 5 As shown, although the protective device 70' can protect the edge of the bent portion A3, there is a gap Q between the second connecting portion 72' and the screen 10. During the use of the electronic device, foreign matter such as grease, sweat, and dust may enter the electronic device through the gap Q. Figure 3 and Figure 4 , the size of the gap Q when the electronic device is in the middle state or even in the closed state is larger than the size when the electronic device is in the unfolded state. In this way, foreign matter such as grease, sweat, dust, etc. can more easily enter the interior of the electronic device when the electronic device is in the middle state or in the closed state.

[0074] Figure 6Another protective device 70" is shown. The protective device 70" includes a first connecting part 71" and a second connecting part 72" that are connected to each other. The first connecting part 71" includes a first supporting part 711" and a second supporting part 712", and the second connecting part 72" is located between the first supporting part 711" and the second supporting part 712". When the protective device 70" is applied to the electronic device 100, at least a part of the second connecting part 72" is located on the screen 10 to protect the screen 10. However, there is also a gap Q between the second connecting part 72" and the screen 10. During the use of the electronic device, foreign matter such as grease, sweat, and dust may enter the electronic device through the gap Q.

[0075] Figure 7 A physical picture of a screen is shown. Figure 7 It can be seen that the screen has multiple different film layers, and there are obvious dividing lines between adjacent film layers. For example, the screen may include the above-mentioned flexible display panel, a covering layer, a supporting layer and an adhesive layer, and the adhesive layer is used to connect two adjacent film layers. When foreign matter such as grease, sweat, and dust enters the electronic device through the gap Q, the foreign matter such as grease, sweat, and dust may contact the side of the screen, thereby reacting with the adhesive layer in the screen, corroding the adhesive layer, and causing peeling problems of multiple film layers in the screen. Figure 7 FIG. 2 shows a situation where two pairs of adjacent film layers in the screen peel off from each other, and gaps W1 and W2 appear in the screen.

[0076] To solve the above problems, Figure 8 As shown, the embodiment of the present application provides another protective device 70, which includes a first connecting portion 71, a second connecting portion 72 and a blocking portion 73. The second connecting portion 72 is located on one side of the first connecting portion 71 and is connected to the first connecting portion 71. The blocking portion 73 is connected to the second connecting portion 72.

[0077] For example, the material of the first connection part 71 may include metal, and the materials of the second connection part 72 and the blocking part 73 may both include polyimide, rubber, metal, etc. The material of the second connection part 72 may be the same as that of the blocking part 73, or may be different.

[0078] like Fig. 9 As shown, when the protective device 70 is set in the electronic device 100, the first connecting portion 71 is connected to the rotating shaft 20, and along the axial direction X of the rotating shaft 20, the first connecting portion 71 is located on one side of the bending portion A3. At least part of the second connecting portion 72 is located on the front side of the bending portion A3, and there is a gap L between the second connecting portion 72 and the bending portion A3. The blocking portion 73 is located in the gap. Among them, the front side of the bending portion A3 is also the side of the bending portion A3 used to display information such as images or videos.

[0079] The above-mentioned “at least part of the second connection part 72 is located on the front side of the bending part A3” may include the case where the entire connection part 72 is located on the front side of the bending part A3, and may also include the case where part of the connection part 72 is located on the front side of the bending part A3.

[0080] For example, the second connection portion 72 may be elastic, so that when the bending portion A3 is bent, the portion of the second connection portion 72 located on the front side of the bending portion A3 may be bent and deformed, and when the bending portion A3 is unfolded, the second connection portion 72 may return to its original state.

[0081] In some examples, such as Fig. 9 As shown, the blocking portion 73 may extend in a direction close to the bending portion A3.

[0082] In the embodiment of the present application, the first connecting portion 71 is connected to the rotating shaft 20, so that the position of the protective device 70 is fixed, and the protective device 70 is not easy to move during the folding or unfolding of the electronic device 100, thereby ensuring the stability of the protective device 70 in use.

[0083] At least a portion of the second connection portion 72 of the protective device 70 is located on the front side of the bending portion A3, and along the axial direction X of the rotating shaft 20. The first connection portion 71 of the protective device 70 is located on one side of the bending portion A3. Both the first connection portion 71 and the second connection portion 72 can block impurities such as sweat, oil droplets, water vapor or dust, thereby preventing impurities such as sweat, oil droplets, water vapor or dust from entering the electronic device and damaging the screen 10.

[0084] Although there is a gap L between the portion of the second connection portion 72 located on the front side of the bent portion A3 and the bent portion A3, the blocking portion 73 is located within the gap L. Fig. 9 and Fig.10 When the electronic device 100 is in the unfolded state and the intermediate state, the maximum distance from the blocking portion 73 to the bent portion A3 can be smaller than the maximum distance from the second connection portion 72 to the bent portion A3, and the blocking portion 73 can even completely close the gap L, and the gap between the protective device 70 and the screen 10 can be smaller or even 0, so that sweat, oil droplets, water vapor, dust and other impurities are not easy to enter the electronic device 100 through the gap between the second connection portion 72 and the screen 10. Of course, when the electronic device 100 is in the closed state, the protective device 70 is provided with the blocking portion 73 to also block sweat, oil droplets, water vapor, dust and other impurities, so that it is not easy to enter the interior of the electronic device 100.

[0085] Compared with the case where the electronic device 100 is in the unfolded state, when the electronic device 100 is in the intermediate state or the closed state, the blocking portion 73 will be squeezed, so that the end of the blocking portion 73 away from the second connecting portion 72 can approach the direction of the bending portion A3, thereby further reducing the gap between the blocking portion 73 and the bending portion A3, and further reducing the gap between the protective device 70 and the screen 10, making it more difficult for impurities such as sweat, oil droplets, water vapor or dust to enter the electronic device 100.

[0086] The protective device provided in the embodiment of the present application can block impurities such as sweat, oil droplets, water vapor or dust, no matter when the electronic device is in the unfolded state, the intermediate state or the closed state, so that impurities such as sweat, oil droplets, water vapor or dust are not easy to enter the electronic device 100 through the gap between the second connecting portion 72 and the bending portion A3 of the screen 10, thereby improving the problem of impurities such as sweat, oil droplets, water vapor or dust entering the electronic device and corroding the edge of the screen, causing the screen film layer to peel off or abnormal noise due to bending, etc., thereby improving the reliability of the electronic device 100 and helping to extend the service life of the electronic device 100.

[0087] In some embodiments, the electronic device 100 may include a protective device 70, and the first connection portion 71 of the protective device 70 may be located on either side of the bent portion A3 in the axial direction X parallel to the rotating shaft 20. The protective device 70 may protect either end of the bent portion A3 in the axial direction X of the rotating shaft 20.

[0088] In other embodiments, Figure 1 As shown, the electronic device 100 may include two protective devices 70. At this time, in the axial direction X parallel to the rotating shaft 20, the bent portion A3 may be located between the first connecting portions 71 of the two protective devices 70. In this way, both ends of the bent portion A3 in the axial direction X of the rotating shaft 20 may be protected by a protective device 70 respectively, and both ends of the bent portion A3 in the axial direction of the rotating shaft 20 are not easily corroded by impurities such as sweat, oil droplets, water vapor or dust.

[0089] It is understandable that, when the screen 10 includes a plurality of bent portions A3, the electronic device 100 may include a plurality of protective devices 70. At this time, one bent portion A3 may correspond to one protective device 70, or may correspond to two protective devices 70 at the same time.

[0090] In some examples, such as Fig. 9As shown, a portion of the second connection portion 72 may also extend to the front of the first non-bending portion A1 and the front of the second non-bending portion A2. At this time, one end of the second connection portion 72 may be located between the first decorative piece 50 and the first non-bending portion A1, and the other end of the second connection portion 72 may be located between the second decorative piece 60 and the second non-bending portion A2. The first decorative piece 50, the second decorative piece 60 and the second connection portion 72 can completely cover the edge of the screen 10, thereby protecting the edge of the screen 10.

[0091] In some embodiments, continue to refer to Fig. 9 The blocking portion 73 includes a first boundary 731 away from the second connecting portion 72, and the distances from different points on the first boundary 731 to the bending portion A3 are the same. It can be understood that the distance from a point on the first boundary 731 to the bending portion A3 can be zero or greater than zero.

[0092] In this way, the minimum distance from different positions of the blocking portion 73 to the bending portion A3 is the same, and the different positions of the blocking portion 73 have the same blocking effect on impurities such as sweat, oil droplets, water vapor or dust, which is beneficial to improve the overall blocking ability of the blocking portion 73 against impurities such as sweat, oil droplets, water vapor or dust, and further protect the screen 10.

[0093] In some embodiments, one end of the blocking portion 73 away from the second connecting portion 72 may abut against the front surface of the bending portion A3, wherein the front surface of the bending portion A3 is also the surface of the bending portion A3 for displaying information such as images or videos.

[0094] In this way, the blocking part 73 contacts the bending part A3, and there is no gap between the blocking part 73 and the bending part A3. The blocking part 73 can effectively block impurities such as sweat, oil droplets, water vapor or dust, thereby preventing impurities such as sweat, oil droplets, water vapor or dust from damaging the screen 10.

[0095] Combine the following Fig. 9 and Fig.11 , the structure of the protection device 70 provided in the embodiment of the present application is described in detail.

[0096] In some embodiments, the thickness of the blocking portion 73 is less than or equal to 0.5 mm. At this time, the thickness of the blocking portion 73 is small, the strength of the blocking portion 73 can be weak, and the blocking portion 73 is not easy to affect the bending of the second connecting portion 72, and is not easy to squeeze the screen 10.

[0097] For example, the thickness of the blocking portion 73 may be 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc.

[0098] In some embodiments, Fig. 9As shown, there is an angle α between the blocking portion 73 and the second connecting portion 72, and the angle α is greater than 0 degrees and less than or equal to 90 degrees. For example, the angle α can be 20 degrees, 30 degrees, 45 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, etc.

[0099] In some examples, the angle α can be greater than or equal to 30 degrees and less than or equal to 70 degrees. In this way, when the size of the blocking portion 73 in the axial direction X of the rotating shaft 20 is fixed, the distance between the blocking portion 73 and the bending portion A3 in the direction perpendicular to the screen 10 can be smaller, so that the blocking portion 73 can better block impurities such as sweat, oil droplets, water vapor or dust. When the blocking portion 73 and the bending portion A3 are against each other, the angle between the blocking portion 73 and the bending portion A3 can be smaller, and the pressure applied by the blocking portion 73 to the bending portion A3 can be smaller, which is conducive to avoiding the problem that the blocking portion 73 squeezes the screen and affects the screen yield.

[0100] like Fig. 9 As shown, in some embodiments, in the axial direction X of the rotating shaft 20, the second connecting portion 72 includes a first edge 721 and a second edge 722, the first edge 721 is closer to the first connecting portion 71 than the second edge 722, and the blocking portion 73 is located between the first edge 721 and the second edge 722.

[0101] In this way, the projection of the blocking portion 73 on the screen 10 is located inside the projection of the second connecting portion 72 on the screen 10. Except for the portion of the screen 10 blocked by the second connecting portion 72, the blocking portion 73 will no longer block other portions of the screen 10. The area of ​​the portion of the screen 10 blocked by the protective device 70 is relatively small, and the protective device 70 is not likely to affect the normal display of the screen 10.

[0102] Fig.11 Schematic diagram of the structure of the second connecting portion 72 and the blocking portion 73 provided in the embodiment of the present application. Figure 8 and Fig.11 As shown, the second connecting portion 72 is arched, and one end of the blocking portion 73 connected to the second connecting portion 72 is arc-shaped.

[0103] In this way, the contact area between the blocking portion 73 and the second connecting portion 72 can be larger, and the connection stability between the blocking portion 73 and the second connecting portion 72 can be better.

[0104] In some examples, the second connection portion 72 and the blocking portion 73 may be an integrated structure. In this way, during the preparation process of the protective device 70, the second connection portion 72 and the blocking portion 73 may be integrally formed, thereby simplifying the preparation steps of the protective device 70 and reducing the preparation cost. At the same time, the connection stability between the second connection portion 72 and the blocking portion 73 may be better, and the structural stability of the protective device 70 may be better.

[0105] Of course, the second connecting portion 72 and the blocking portion 73 can also be formed separately and then fixedly connected together.

[0106] In some embodiments, Fig. 9 As shown, the protective device 70 may further include a third connecting portion 74, the third connecting portion 74 includes a first sub-portion 741 and a second sub-portion 742 connected to each other, the first sub-portion 741 extends in a direction Y perpendicular to the screen 10, and the second sub-portion 742 extends in a direction parallel to the screen 10. The first sub-portion 741 is connected to the first connecting portion 71, and the second sub-portion 742 is connected to the second connecting portion 72. The second connecting portion 72 has a groove T on its surface facing the third connecting portion 74, and the second sub-portion 742 extends into the groove T.

[0107] Exemplarily, the material of the third connection portion 74 may include metal, such as steel, etc. The first sub-portion 741 may be welded on the first connection portion 71 to be fixedly connected to the first connection portion 71 .

[0108] The first sub-portion 741 extends in a direction perpendicular to the screen 10, and the first sub-portion 741 is connected to the first connecting portion 71. The contact area between the first sub-portion 741 and the first connecting portion 71 can be large, and the connection stability between the first sub-portion 741 and the first connecting portion 71 is good. The second sub-portion 742 extends in a direction parallel to the screen 10, and the second sub-portion 742 extends into the groove T of the second connecting portion 72. The contact area between the second sub-portion 742 and the second connecting portion 72 can also be large, and the connection between the second sub-portion 742 and the second connecting portion 72 can be relatively stable. In this way, the third connecting portion 74 can be relatively stably connected to the first connecting portion 71 and the second connecting portion 72, so that the overall stability of the protective device 70 is good.

[0109] like Fig.12 As shown, in some embodiments, the electronic device 100 may further include a protective layer 80 , which covers the side of the screen 10 .

[0110] In the embodiment of the present application, a protective layer 80 is also provided on the side of the screen 10 while the protective device 70 is provided. In this way, even if impurities such as sweat, oil droplets, water vapor or dust enter the interior of the electronic device 100 through the gap between the blocking portion and the bending portion, the protective layer 80 can separate the impurities such as sweat, oil droplets, water vapor or dust from the side of the screen 10, further improving the problem that impurities such as sweat, oil droplets, water vapor or dust corrode the screen and affect the screen display, and damage the adhesive layer to cause the separation of multiple film layers inside the screen or abnormal bending and noise.

[0111] In some examples, the protective layer 80 may include at least one of a fluorinated liquid coating, a glue coating, and an ink layer. In this way, on the one hand, the fluorinated liquid coating, the glue coating, and the ink layer have better ability to block grease and water vapor, which is conducive to improving the ability of the protective layer 80 to block impurities such as sweat, oil droplets, water vapor, or dust. On the other hand, the fluorinated liquid, the glue, and the ink are all fluid, and the uniformity of the protective layer 80 formed by the fluorinated liquid, the glue, and the ink can be better, and the protective layer 80 can evenly cover the side of the screen 10, thereby better protecting the screen 10.

[0112] Taking the protective layer 80 as an example, the protective layer 80 includes a fluorinated liquid coating. Fig.13 A side view of the screen is shown before spraying the fluorinated liquid and after spraying the fluorinated liquid multiple times. Fig.13 The side of the screen shown in (a) is not sprayed with fluorinated liquid. Fig.13 It can be seen from (a) that the screen 10 has multiple different film layers, which may include the flexible display panel, cover layer, support layer and adhesive layer mentioned in the above embodiment, and may also include other film layers. There is a clear dividing line between adjacent film layers.

[0113] Fig.13 The sides of the screens shown in (b), (c), and (d) are all sprayed with fluoride liquid, and the number of times the fluoride liquid is sprayed on the sides of the screens shown in (b), (c), and (d) gradually increases. Fig.13 From (b), (c), (d) and (a), it can be seen that as the number of times the fluorinated liquid is sprayed increases, the boundaries between the various film layers in the screen 10 become less and less obvious, which means that the fluorinated liquid coating has a good covering effect on the sides of the various film layers in the screen and the boundaries between the various film layers, thereby effectively preventing sweat, oil droplets, water vapor or dust and other impurities from eroding the various film layers of the screen, especially the adhesive layer in the screen, and protecting the screen.

[0114] In some examples, the thickness of the protective layer 80 may be less than or equal to 0.02 micrometers. For example, the thickness of the protective layer 80 may be 0.005 micrometers, 0.01 micrometers, 0.015 micrometers, or 0.02 micrometers, etc. In this way, the thickness of the protective layer 80 may be smaller, and the preparation cost of the protective layer 80 may be lower.

[0115] See also Fig.12 The embodiment of the present application may also provide another electronic device 200 . The electronic device 200 includes a screen 10 and a protective layer 80 , wherein the protective layer 80 covers the side of the screen 10 .

[0116] For example, Fig.12As shown, the screen 10 may include a flexible display panel 11, a cover layer 12, a support layer 13 and an adhesive layer 14. The flexible display panel 11 is located between the cover layer 12 and the support layer 13. An adhesive layer 14 is provided between the flexible display panel 11 and the cover layer 12, and between the flexible display panel 11 and the support layer 13. The structures and materials of the display panel 11, the cover layer 12, the support layer 13 and the adhesive layer 14 can refer to the above embodiments, and the present application will not repeat them here.

[0117] Of course, in addition to the flexible display panel 11, the covering layer 12, the supporting layer 13 and the adhesive layer 14, the screen 10 may also include other film layers, which is not limited in the present application and can be configured according to actual needs.

[0118] In the electronic device 200 provided in the embodiment of the present application, the protective layer 80 covers the side of the screen 10, thereby protecting the side of the screen 10, preventing sweat, oil droplets, water vapor, dust and other impurities from corroding the side of the screen and affecting the screen display, and preventing sweat, oil droplets, water vapor, dust and other impurities from damaging the adhesive layer, causing problems such as separation or bending of multiple film layers inside the screen and abnormal noise.

[0119] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0120] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
