Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic equipment and a protective film set. Background Art

[0002] As the technology of flexible display screens matures, more and more types of foldable phones are available. Foldable phones can be folded to have a smaller size and a larger display area, providing a better user experience.

[0003] However, when using a foldable phone, the user may drop the phone, which may easily cause damage to the screen such as bright lines on the screen. Utility Model Content

[0004] The purpose of the embodiment of the present application is to provide an electronic device and a protective film set. The electronic device of the embodiment of the present application protects the flexible display screen through the protective film, thereby increasing the service life of the flexible display screen and thus increasing the service life of the electronic device.

[0005] In a first aspect, an embodiment of the present application provides an electronic device, including:

[0006] The housing device comprises a first housing, a second housing and a folding assembly, wherein the folding assembly is connected between the first housing and the second housing, and the first housing and the second housing can be relatively unfolded or folded through the movement of the folding assembly;

[0007] A flexible display screen, comprising a first part, a second part and a third part, wherein the third part is connected between the first part and the second part, the first part is mounted on a first shell, the second part is mounted on a second shell, and the third part is deformed during the relative unfolding or folding of the first shell and the second shell; and

[0008] A protective film continuously covers at least a portion of the first portion, at least a portion of the third portion and at least a portion of the second portion, and the protective film includes a protrusion, which is at least partially protruding from the end side of the third portion in the length direction of the folding component.

[0009] In electronic devices, the third part of the flexible display screen needs to be deformed to adapt to the folding and unfolding of the electronic device, and therefore it is difficult to protect it directly by wrapping the shell device. In addition, during the use of the electronic device, there are situations where it is subject to large impacts such as falling. The side of the third part usually has wiring, and if it is damaged, the display of the third part may easily fail (such as bright lines). Therefore, a gap needs to be left between the side of the third part and the large end or small end of the shell device to prevent the side of the third part from being directly impacted and failing.

[0010] In this embodiment, by providing a protrusion on the protective film and making the protrusion protrude relative to the third part, the protrusion of the protective film can block the end side of the third part of the flexible display screen, which can prevent the impact of external force on the third part, thereby protecting the third part, improving the service life of the flexible display screen, and thus improving the service life of the electronic device. In addition, the protrusion of the protective film can block part of the gap between the third part and the shell device, improve the aesthetics of the electronic device, and reduce the entry of external dust into the interior of the electronic device. In addition, the protrusion of the protective film can also prevent the user from digging the side of the third part during use and damaging the third part, which can also improve the service life of the electronic device.

[0011] In some embodiments, the protective film further includes a main body portion, which is fixed to the first portion, the third portion, and the second portion in sequence along the first direction;

[0012] There are multiple protrusions, and every two protrusions are arranged in a group. The two protrusions in the same group are arranged in the length direction of the folding component and are respectively fixed on opposite sides of the main body. The length direction of the folding component is perpendicular to the first direction, and the protrusions are protruding relative to the main body.

[0013] In this embodiment, the main body protects the flexible display screen by fitting most of the structure of the flexible display screen, and the protrusion is arranged to correspond to the third part of the flexible display screen that needs to be bent to protect the end side of the third part, thereby better and specifically protecting the flexible display screen.

[0014] In some embodiments, the protrusion includes a first side surface and a transition surface, the main body includes a second side surface, the first side surface and the second side surface are both planes and parallel to each other, and the first side surface is smoothly connected to the second side surface through the transition surface.

[0015] In this embodiment, the first side surface is a plane, which can make the protrusion roughly in the shape of a long strip, which is beneficial for the protrusion to evenly cover the end side of the third part of the flexible display screen, thereby improving the protective performance of the protective film; by setting the transition surface, the protrusion is easier to shape, and the stress of the protrusion during bending and deformation can be reduced, thereby improving the service life of the protective film.

[0016] In some embodiments, the transition surface includes a first arc surface, a connecting surface and a second arc surface, the connecting surface is located between the first arc surface and the second arc surface, the first arc surface is fixedly connected to the first side surface, and the second arc surface is fixedly connected to the second side surface.

[0017] Exemplarily, the center of the first arc surface can be located inside the protective film, and the center of the second arc surface can be located outside the protective film, so that the bending direction of the first arc surface is toward the outside of the protective film, and the bending direction of the second arc surface is toward the inside of the protective film. In addition, the connecting surface can be a plane.

[0018] In this embodiment, by setting the structure of the transition surface, the overall curvature of the transition surface is small, the extension of the transition surface is smoother, the stress distribution of the structure where the transition surface is located is more uniform when the protrusion is bent, and the service life of the protective film is longer.

[0019] In some embodiments, a protruding distance of the protrusion relative to the end side of the third portion of the flexible display screen is less than or equal to 0.5 mm; or a protruding distance of the protrusion relative to the end side of the third portion of the flexible display screen is in a range of 0.1 mm to 0.2 mm.

[0020] In this embodiment, by reasonably setting the protruding distance of the protrusion relative to the third part of the flexible display screen, the protrusion can protect the end side of the third part of the flexible display screen, and the protrusion is not easy to warp up and contact with the shell device, thereby improving the service life of the protective film.

[0021] In some embodiments, the electronic device further includes a buffer component, which is fixedly connected to the end side surface of the third portion and abuts against the bottom surface of the protruding portion.

[0022] In this embodiment, the buffer component can protect the end side of the third part so that external force cannot directly contact the end side of the third part, thereby protecting the flexible display screen; the buffer component can provide support for the protrusion by abutting the bottom surface of the protrusion to prevent the protrusion from warping or collapsing relative to the flexible display screen.

[0023] In some embodiments, in the arrangement direction of the first part, the second part and the third part, the protrusion protruding relative to the third part has a first length, and the buffer has a second length; the second length is greater than or equal to half of the first length.

[0024] In this embodiment, by setting the length of the buffer component, the buffer component has a better protection capability for the end side of the third portion and is easy to manufacture.

[0025] In some embodiments, the buffer is a colloid; or, the buffer is an ultraviolet curing glue or a hot melt glue.

[0026] In this embodiment, by setting the material of the buffer, the buffer can be bonded to the flexible display screen according to its own material characteristics, without the need for additional adhesives, making the manufacturing process more convenient and ensuring that the buffer has good protection performance.

[0027] In some embodiments, on the side of the flexible display along the length direction of the folding component, a partial area or the entire area of ​​the end side of the third part forms a recessed area, and the recessed area is concave relative to the side of the first part and the side of the second part.

[0028] In this embodiment, when the flexible display screen is mounted on the housing device, a gap is formed between the recessed area and the housing device, preventing the housing device from directly contacting the end side of the third part, thereby facilitating protection of the end side of the third part.

[0029] In some embodiments, in the arrangement direction of the first portion, the second portion, and the third portion, the wall surface of the recessed area includes a first wall surface, a bottom wall surface, and a second wall surface;

[0030] In a direction perpendicular to the flexible display screen, the side surface of the protruding portion intersects with the first wall surface and the second wall surface, and the protruding portion covers the bottom wall surface.

[0031] In this embodiment, the protruding portion of the protective film can at least block the bottom wall surface of the recessed area of ​​the flexible display screen and partial areas of the first wall surface and the second wall surface, so that the covered portion of the end side surface of the third part cannot be directly exposed to the external space, thereby protecting the bottom wall surface and partial areas of the first wall surface and the second wall surface, and increasing the protection area of ​​the protruding portion for the third part.

[0032] In some embodiments, the folding assembly includes a main shaft, a first support plate and a second support plate, the first support plate and the second support plate are both movably connected to the main shaft, and in the process of relative expansion or folding of the first shell and the second shell, the first support plate and the second support plate can be relatively expanded or folded;

[0033] In the arrangement direction of the first part, the second part and the third part, the ratio of the length of the protrusion to the width of the arrangement area of ​​the main axis, the first support plate and the second support plate is greater than or equal to 1.

[0034] The arrangement area of ​​the main axis, the first support plate and the second support plate is the main deformation area of ​​the shell device. Correspondingly, the third part of the flexible display screen needs to cover the deformation area so that the flexible display screen can deform along with the deformation of the shell device.

[0035] In this embodiment, a gap is left between the end side of the third part and the ends of the main shaft, the first support plate and the second support plate to reduce the contact between the third part and the main shaft, the first support plate and the second support plate, thereby reducing damage to the third part and improving the service life of the flexible display screen.

[0036] In some embodiments, the housing device further includes a first protective frame and a second protective frame. The first protective frame is fixed to the first housing and covers at least part of the edge of the first part; the second protective frame covers at least part of the edge of the second part;

[0037] The edge of the protective film is exposed relative to the first protective frame and the second protective frame.

[0038] Exemplarily, the first protective frame is in a "匚" shape, and the second protective frame is in an inverted "匚" shape.

[0039] In this embodiment, the protective film is not covered by the first protective frame. A gap can be left between the edge of the protective film and the first protective frame so that the protective film does not directly contact the first protective frame, while the edge of the flexible display screen can be covered by the first protective frame. At this time, the first protective frame and the second protective frame can fix and protect the edge of the flexible display screen, facilitate the installation of the protective film, and during the later use of the electronic device, it is easy to replace the protective film; when replacing, the original protective film on the electronic device can be torn off, and then a new protective film can be attached to the flexible display screen to complete the replacement of the protective film.

[0040] In a second aspect, an embodiment of the present application provides a protective film set, including a protective film and a release film. The protective film is used to be fixed to the flexible display screen of the electronic device, and the release film is attached to the protective film;

[0041] The protective film includes a main body portion and a protruding portion. The protruding portion protrudes from the side surface of the main body portion; the protruding portion includes a first side surface and a transition surface, and the main body portion includes a second side surface. Both the first side surface and the second side surface are flat surfaces, and the first side surface is smoothly connected to the second side surface through the transition surface.

[0042] In this embodiment, the release film can protect the protective film and facilitate the storage and transportation of the protective film set. The protective film is provided with a protruding portion. When the protective film is applied to the flexible display screen, the protruding portion of the protective film can block a part of the flexible display screen, so as to provide more targeted protection and make the protection performance of the protective film better.

[0043] In some embodiments, the number of protruding portions is multiple, and every two protruding portions are set in a group. The two protruding portions in the same group are arranged in a second direction and are respectively fixed to opposite sides of the main body portion.

[0044] In this embodiment, by setting the protruding portions in groups, it is beneficial to make the protruding portions correspond to the parts of the flexible display screen that need to be bent, so as to protect the end side surfaces of the parts of the flexible display screen that need to be bent.

[0045] In some embodiments, the protective film includes a substrate layer and a colloid layer. The substrate layer is fixedly connected to the colloid layer, and the release film is attached to the colloid layer.

[0046] In this embodiment, the protective film is used to connect the flexible display screen through the colloidal layer. Since the colloidal layer of the protective film can be torn off from the flexible display screen, the protective film can be easily removed from the flexible display screen, and the protective film can be easily replaced, thereby extending the service life of the electronic device.

[0067] In the embodiments of the present application, the limitations of the relative position relationship mentioned, such as parallel, vertical, aligned, etc. These limitations are all for the current state of the art, rather than absolutely strict limitations, and a small amount of deviation is allowed, and it is possible to be approximately parallel, approximately vertical, approximately aligned, etc. For example, A and B are parallel, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. For example, A and B are perpendicular, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0068] In the embodiments of the present application, the terms "first", "second", "third", and "fourth" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", "third", and "fourth" may explicitly or implicitly include one or more of the features.

[0069] Please also read Figure 1 to Figure 2 , Figure 1 is a structural diagram of an electronic device 10 provided in an embodiment of the present application when it is in an open state. Figure 2 yes Figure 1 An exploded schematic diagram of the electronic device 10 is shown.

[0070] In some embodiments, the electronic device 10 includes a housing device 1, a flexible display screen 2, and a protective film 3. The flexible display screen 2 is fixed to the housing device 1, and the protective film 3 is fixed to the flexible display screen 2.

[0071] The electronic device 10 may be a foldable electronic product such as a mobile phone, a tablet computer, a laptop computer, a wearable device, etc. The wearable device may be a smart watch, a smart bracelet, etc. For example, the electronic device 10 may be a two-fold folding mobile phone that folds inward or a two-fold folding mobile phone that folds outward, or a three-fold folding mobile phone with two outward folding parts, a three-fold folding mobile phone with two inward folding parts, or a three-fold folding mobile phone with an inward folding part and an outward folding part, which is not strictly limited in this embodiment. This embodiment is described by taking the electronic device 10 as a two-fold folding mobile phone that folds outward as an example.

[0072] In some examples, the housing device 1 includes a first housing 11, a folding assembly 12, and a second housing 13 connected in sequence. The folding assembly 12 is connected between the first housing 11 and the second housing 13. Through the deformation movement of the folding assembly 12, the first housing 11 and the second housing 13 can be relatively unfolded or folded.

[0073] like Figure 1 As shown, the first shell 11 and the second shell 13 can be relatively unfolded to an open state, so that the electronic device 10 is in an open state. For example, when the first shell 11 and the second shell 13 are in an open state, the angle between the two can be approximately 180°, but a slight deviation can be allowed, such as 165°, 177° or 185°. At this time, the electronic device 10 has a larger width dimension, the plane dimension of the electronic device 10 is large, and the user experience is better.

[0074] It is understandable that the first housing 11 and the second housing 13 can also be folded relative to each other to a closed state, so that the electronic device 10 is in a closed state. Exemplarily, when the first housing 11 and the second housing 13 are in a closed state, the two can be completely folded to be parallel to each other, but a slight deviation can be allowed.

[0075] In addition, the electronic device 10 can also be in an intermediate state between the open state and the closed state, and at this time, the angle between the first shell 11 and the second shell 13 can be greater than the angle between the two in the closed state and smaller than the angle between the two in the open state. Therefore, the electronic device 10 can switch between the open state, the intermediate state and the closed state by deforming the folding component 12.

[0076] In some examples, the flexible display screen 2 may include a first portion 21, a third portion 22, and a second portion 23 arranged in sequence. The third portion 22 is connected between the first portion 21 and the second portion 23, the first portion 21 is mounted on the first housing 11, the second portion 23 is mounted on the second housing 13, and the third portion 22 may be deformed during the relative unfolding or folding of the first housing 11 and the second housing 13.

[0077] Exemplarily, the electronic device 10 may include an adhesive layer 4, and the flexible display screen 2 may be bonded to the housing device 1 through the adhesive layer 4. For example, the first part 21, the third part 22, and the second part 23 may be respectively arranged in a one-to-one correspondence with the first housing 11, the folding component 12, and the second housing 13, and bonded in a one-to-one correspondence through the adhesive layer 4. For another example, the first part 21 and the second part 23 may be respectively arranged in a one-to-one correspondence with the first housing 11 and the second housing 13, and bonded in a one-to-one correspondence through the adhesive layer 4, and the third part 22 may not be bonded to the folding component 12. In addition, the adhesive layer 4 may be made of materials such as foam glue, which is not strictly limited in this example.

[0078] Wherein, the flexible display screen 2 is used to display images. Exemplarily, the flexible display screen 2 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a microorganic light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, or a quantum dot light-emitting diode (QLED) display screen.

[0079] The flexible display screen 2 may have a first surface 24 and a second surface 25 opposite to each other. The first surface 24 may be used for fixed connection with the housing device 1, and the second surface 25 may be used for facing outward to display images to the outside.

[0080] The flexible display screen 2 may be formed by stacking multiple layers of films. For example, the flexible display screen 2 may have a glass substrate, a light-emitting layer, and an encapsulation layer, and the encapsulation layer may be used to protect the light-emitting layer and other structures. The present embodiment does not strictly limit the layers constituting the flexible display screen 2.

[0081] Exemplarily, when the first shell 11 and the second shell 13 are in an open state, the flexible display screen 2 is in an open state. At this time, the first part 21, the third part 22 and the second part 23 can be coplanar, so that the flexible display screen 2 can be flat or approximately flat in shape, with a large display area and a better user experience.

[0082] It is understandable that when the first shell 11 and the second shell 13 are in a closed state, the flexible display screen 2 is in a closed state. At this time, the first part 21 and the second part 23 can be in a parallel or approximately parallel state, and the third part 22 is in a bent state. At this time, the flexible display screen 2 faces the outside of the electronic device 10, and the flexible display screen 2 can be double-sided display (i.e., the first part 21 and the second part 23 both display images) according to the usage scenario, or it can be single-sided display (i.e., the first part 21 or the second part 23 displays images) to improve the user experience. It is understandable that this embodiment does not strictly limit the specific display mode of the flexible display screen 2 when it is in various forms.

[0083] In some embodiments, when the first shell 11 and the second shell 13 are in an intermediate state, the flexible display screen 2 is in an intermediate state between the open state and the closed state.

[0084] In some examples, the protective film 3 can be fixed to the surface of the top side of the flexible display screen 2. For example, the protective film 3 can be fixed to the second surface 25 of the flexible display screen 2.

[0085] Exemplarily, the protective film 3 may cover most of the area of ​​the flexible display screen 2. For example, the protective film 3 may continuously cover at least part of the first part 21, at least part of the third part 22, and at least part of the second part 23. The protective film 3 is used to protect the area covered by it to prevent the impact and scratching of the flexible display screen 2 by external forces, thereby improving the service life of the flexible display screen 2. In some other embodiments, the protective film 3 may fully cover one or more of the first part 21, the second part 23, and the third part 22 of the flexible display screen 2, which is not strictly limited in this embodiment.

[0086] The protective film 3 may include a base layer and a colloid layer. The base layer faces the outside of the electronic device 10, and the colloid layer is located between the flexible display screen 2 and the base layer. The base layer and the colloid layer may be fixedly connected, and the colloid layer may be bonded to the flexible display screen 2, thereby fixing the protective film 3 to the flexible display screen 2. The colloid layer may be made of OCA (Optically Clear Adhesive) glue, and this example does not strictly limit the material of the colloid layer. At this time, the protective film 3 is connected to the flexible display screen 2 through the colloid layer. Since the colloid layer of the protective film 3 can be torn off from the flexible display screen 2, it is convenient to remove the protective film 3 from the flexible display screen 2, and it is convenient to replace the protective film 3, so that the service life of the electronic device 10 is longer.

[0087] The protective film 3 may be made of a flexible material. When the flexible display screen 2 is folded or unfolded, the protective film 3 can be folded or unfolded synchronously with the flexible display screen 2, so that the electronic device 10 can be folded or unfolded as a whole.

[0088] In this embodiment, the flexible display screen 2 can be unfolded or folded with the housing device 1. When the electronic device 10 is in an open state, the flexible display screen 2 is in a flattened state and can be displayed in full screen, so that the electronic device 10 has a larger display area to improve the user's viewing experience. When the electronic device 10 is in a closed state, the plane size of the electronic device 10 is small (with a small width dimension), which is convenient for users to carry and store. The protective film 3 covers the flexible display screen 2 to prevent external forces from impacting and scratching the flexible display screen 2, thereby protecting the flexible display screen 2 and improving the service life of the flexible display screen 2.

[0089] In some embodiments, the electronic device 10 may further include multiple modules (not shown in the figure), and the multiple modules may be housed inside the housing device 1. The multiple modules of the electronic device 10 may include but are not limited to a mainboard, a processor, a memory, a battery, a camera module, an earpiece module, a speaker module, a microphone module, an antenna module, a sensor module, etc. The embodiment of the present application does not specifically limit the number, type, position, etc. of the modules of the electronic device 10.

[0090] It is understandable that when the user holds the electronic device 10, the position of the earpiece module of the electronic device 10 can be defined as the upper side of the electronic device 10, the position of the microphone module of the electronic device 10 can be defined as the lower side of the electronic device 10, and the two sides of the electronic device 10 held by the left and right hands of the user can be defined as the left and right sides of the electronic device 10. In some embodiments, the electronic device 10 can be folded in half left and right. In some other embodiments, the electronic device 10 can be folded in half up and down.

[0091] It is understandable that this embodiment is described by taking "the rotation axis of the electronic device 10 is parallel to the length direction of the electronic device 10" as an example. In this case, the electronic device 10 can rotate left and right, and the folding and unfolding of the electronic device 10 affects the width dimension of the electronic device 10. In the relevant description of the electronic device 10, the side of the electronic device 10 with the flexible display screen 2 is the "top", and the side of the electronic device 10 away from the flexible display screen 2 is the "bottom". In some other embodiments, the rotation axis of the electronic device 10 may also be parallel to the width direction of the electronic device 10. In this case, the electronic device 10 can rotate up and down, and the folding and unfolding of the electronic device 10 affects the length dimension of the electronic device 10.

[0092] It can be understood that the width direction of the electronic device 10 is the X direction, the length direction of the electronic device 10 is the Y direction, and the thickness direction of the electronic device 10 is the Z direction.

[0093] Please refer to Figure 2 and Figure 3 , Figure 3 yes Figure 1 An enlarged view of point A of the housing device 1 is shown.

[0094] In some embodiments, the folding assembly 12 may include a first connection portion 121, a first support plate 122, a main shaft 123, a second support plate 124, and a second connection portion 125. The first connection portion 121, the first support plate 122, the main shaft 123, the second support plate 124, and the second connection portion 125 are arranged in sequence. The first connection portion 121, the first support plate 122, and the main shaft 123 may be connected by a first connection mechanism so that the three can move relative to each other. The main shaft 123, the second support plate 124, and the second connection portion 125 may be connected by a second connection mechanism so that the three can move relative to each other.

[0095] Exemplarily, the main shaft 123 can have a large end 1231, and the large end 1231 of the main shaft 123 can be located at both ends of the main shaft 123 and protrude radially of the main shaft 123, so that the large end 1231 has a larger area, which can be used to protect the end of the main shaft 123, thereby protecting the end of the folding component 12, preventing external forces from damaging the inside of the folding component 12, and preventing external dust and the like from entering the folding component 12.

[0096] Exemplarily, the first connection portion 121 and the second connection portion 125 may be a plate-like structure. The first connection portion 121 may be rotatably connected to the main shaft 123 and may rotate relative to the main shaft 123. The first connection portion 121 is used to be fixedly connected to the first shell 11. The second connection portion 125 may be rotatably connected to the main shaft 123 and may rotate relative to the main shaft 123. The second connection portion 125 is used to be fixedly connected to the second shell 13. By rotating the first connection portion 121 and the second connection portion 125 relative to the main shaft 123, the deformation of the folding assembly 12 is realized, thereby driving the first shell 11 and the second shell 13 to rotate, and realizing the unfolding and folding of the shell device 1.

[0097] Exemplarily, the first support plate 122 and the second support plate 124 are both movably connected to the main shaft 123 , and when the first shell 11 and the second shell 13 are relatively unfolded or folded, the first support plate 122 and the second support plate 124 can be relatively unfolded or folded.

[0098] The first support plate 122 and the second support plate 124 may have a curved surface on one side close to the flexible display screen 2 to better support the flexible display screen 2. The first support plate 122 and the second support plate 124 may have small ends 1221, which may be located at both ends of the first support plate 122 and the second support plate 124, respectively, and protrude radially from the first support plate 122 and the second support plate 124. The small ends 1221 may be used to respectively protect the first support plate 122 and the second support plate 124, thereby protecting the folding assembly 12.

[0099] The first support plate 122 can be rotatably connected to the main shaft 123 and can rotate relative to the main shaft 123. The second connection portion 125 can be rotatably connected to the main shaft 123 and can rotate relative to the main shaft 123. By making the first support plate 122 and the second support plate 124 both rotatably connected to the main shaft 123, when the folding assembly 12 is deformed, the first support plate 122 and the second support can continue to support the flexible display screen 2.

[0100] In some examples, the first connection part 121, the first support plate 122, the main shaft 123, the second support plate 124 and the second connection part 125 can be linked together, and this embodiment does not strictly limit the structure of the first connection part 121, the first support plate 122, the main shaft 123, the second support plate 124 and the second connection part 125 and the connection method therebetween.

[0101] In some embodiments, the first housing 11 may be substantially in a plate-like structure. The first housing 11 may be fixedly connected to the first connecting portion 121 of the folding assembly 12 by means of fasteners such as screws, so that the first housing 11 is fixedly connected to the folding assembly 12. The first housing 11 may be made of metal or plastic material, which is not strictly limited in this embodiment.

[0102] The first housing 11 may have a first supporting surface 111. The first supporting surface 111 may be located on the top side of the first housing 11, the first supporting surface 111 may be a plane, and the first supporting surface 111 may be used to support the first portion 21 of the flexible display screen 2. The first supporting surface 111 may be fixedly connected with an adhesive layer 4 so that the adhesive layer 4 is bonded to the first portion 21 of the flexible display screen 2.

[0103] In some embodiments, the second housing 13 may be a substantially plate-shaped structure. The second housing 13 may be fixedly connected to the second connecting portion 125 of the folding assembly 12 by means of fasteners such as screws, so that the second housing 13 is fixedly connected to the folding assembly 12. The second housing 13 may be made of metal or plastic material, which is not strictly limited in this embodiment.

[0104] The second housing 13 may have a second supporting surface 131. The second supporting surface 131 may be located on the top side of the second housing 13, the second supporting surface 131 may be a plane, and the second supporting surface 131 may be used to support the second portion 23 of the flexible display screen 2. The second supporting surface 131 may be fixedly connected with an adhesive layer 4 so that the adhesive layer 4 is bonded to the second portion 23 of the flexible display screen 2.

[0105] In some embodiments, the housing device 1 further includes a first protective frame 5 and a second protective frame 6 .

[0106] Exemplarily, the first protective frame 5 can be in a "C" shape. The first protective frame 5 can be formed by sequentially connecting three side strips to form a "C" shape structure. Among the three side strips, the two adjacent side strips can be approximately at a 90° angle. The first protective frame 5 can be an integral structural member to increase its overall strength.

[0107] Exemplarily, the first protective frame 5 can be fixed to the first housing 11. The first protective frame 5 can be fixed to the first support surface 111 of the first housing 11. For example, the three side strips of the first protective frame 5 can respectively correspond to the three outer sides of the first housing 11, and the first protective frame 5 and the first housing 11 can be fixedly connected by glue.

[0108] Exemplarily, the first protective frame 5 can cover at least part of the edge of the first part 21. For example, a first installation groove can be formed between the edge of the first housing 11 and the first protective frame 5. A gap can be left between the bottom surface of the first protective frame 5 and the first support surface 111 to form the accommodation space of the first installation groove. The first installation groove can be used to install the edge of the first part 21 of the flexible display screen 2 to better protect the flexible display screen 2. In some other examples, the first installation groove can also be used to accommodate part of the edge of the third part 22, and this embodiment does not strictly limit this.

[0109] Among them, referring to Figure 3 , the edge of the protective film 3 can be exposed relative to the first protective frame 5. Among them, the protective film 3 is equivalent to not being covered by the first protective frame 5, and a gap can be left between the edge of the protective film 3 and the first protective frame 5 so that the protective film 3 does not directly contact the first protective frame 5, while the edge of the flexible display screen 2 can be covered by the first protective frame 5. At this time, the first protective frame 5 can fix and protect the edge of the flexible display screen 2, and facilitate the installation of the protective film 3. And during the later use of the electronic device 10, it is easy to replace the protective film 3; when replacing, the original protective film 3 on the electronic device 10 can be torn off, and then the new protective film 3 can be attached to the flexible display screen 2 to complete the replacement of the protective film 3.

[0110] Exemplarily, the second protective frame 6 can be in an inverted "C" shape. The second protective frame 6 can be formed by sequentially connecting three side strips to form an inverted "C" shape structure. Among the three side strips, the two adjacent side strips can be approximately at a 90° angle. The second protective frame 6 can be an integral structural member to increase its overall strength.

[0111] Exemplarily, the second protective frame 6 can be fixed to the second housing 13. The second protective frame 6 can be fixed to the first support surface 111 of the second housing 13. For example, the three side strips of the second protective frame 6 can respectively correspond to the three outer sides of the second housing 13, and the second protective frame 6 and the second housing 13 can be fixedly connected by glue.

[0112] Exemplarily, the second protective frame 6 may cover at least a portion of the edge of the second portion 23. For example, a second mounting groove may be formed at the edge of the second shell 13 and the second protective frame 6. A gap may be left between the bottom surface of the second protective frame 6 and the first supporting surface 111 to form a receiving space for the second mounting groove. The second mounting groove may be used to mount the edge of the second portion 23 of the flexible display 2 to better protect the flexible display 2. In some other examples, the second mounting groove may also be used to accommodate a portion of the edge of the third portion 22, which is not strictly limited in this embodiment.

[0113] For example, the edge of the protective film 3 may be exposed relative to the second protective frame 6. At this time, the protective film 3 is equivalent to not being covered by the second protective frame 6, and a gap may be left between the edge of the protective film 3 and the second protective frame 6, so that the protective film 3 does not directly contact the second protective frame 6, so as to facilitate the installation of the protective film 3, and also facilitate the replacement of the protective film 3 during the later use of the electronic device 10; when replacing, the original protective film 3 in the electronic device 10 can be torn off, and then the new protective film 3 can be attached to the flexible display screen 2, so that the replacement of the protective film 3 can be completed.

[0114] In this embodiment, by providing the first protective frame 5 and the second protective frame 6, the first protective frame 5 and the second protective frame 6 respectively cover the edges of the first part 21 and the second part 23, so as to better fix and protect the flexible display screen 2, and improve the reliability and service life of the flexible display screen 2; by exposing the edge of the protective film 3 relative to the first protective frame 5 and the second protective frame 6, and exposing the protective film 3 relative to the shell device 1, the protective film 3 is easy to disassemble and assemble, thereby facilitating users or maintenance personnel to replace the protective film 3 of the electronic device 10.

[0115] See also Figure 4 , Figure 4 yes Figure 1 The schematic diagram of the structure of the flexible display screen 2 and the protective film 3 is shown.

[0116] In some embodiments, the protective film 3 may continuously cover at least a portion of the first portion 21, at least a portion of the third portion 22, and at least a portion of the second portion 23; and the protective film 3 may include a protrusion 31, and the protrusion 31 is at least partially protruding relative to the end side surface of the third portion 22. It can be understood that the end side surface of the third portion 22 refers to the side surfaces of the two ends of the third portion 22 in the length direction (i.e., the Y direction).

[0117] In the electronic device 10, the third part 22 of the flexible display screen 2 needs to be deformed to adapt to the folding and unfolding of the electronic device 10, so it is difficult to protect it directly by wrapping the shell device 1; and during the use of the electronic device 10, there is a situation where there is a large impact such as falling, and the side of the third part 22 usually has wiring, which is easy to cause the third part 22 to display failure (such as bright lines) after being damaged, so it is necessary to connect the side of the third part 22 with the large end 1231 or the small end 1221 of the shell device 1 (see Figure 2 ) to prevent the side of the third part 22 from being directly impacted and failing.

[0118] In this embodiment, by providing a protrusion 31 on the protective film 3 and making the protrusion 31 protrude relative to the third part 22, the protrusion 31 of the protective film 3 can block the end side of the third part 22 of the flexible display screen 2, and can prevent the impact of external force on the third part 22, thereby protecting the end side of the third part 22, improving the service life of the flexible display screen 2, and thus improving the service life of the electronic device 10. In addition, the protrusion 31 of the protective film 3 can block part of the gap between the third part 22 and the housing device 1, improve the aesthetics of the electronic device 10, and reduce external dust and the like from entering the interior of the electronic device 10. In addition, the protrusion 31 of the protective film 3 can also prevent the user from scratching the end side of the third part 22 during use and damaging the third part 22, and can also improve the service life of the electronic device 10.

[0119] Exemplarily, the area of ​​the protective film 3 may be smaller than the area of ​​the flexible display screen 2. For example, the edge of the first portion 21 of the flexible display screen 2 may protrude relative to the edge of the corresponding position of the protective film 3, the edge of the second portion 23 of the flexible display screen 2 may protrude relative to the edge of the corresponding position of the protective film 3, and part of the edge of the third portion 22 of the flexible display screen 2 may be retracted relative to the protective film. Since the areas of the first portion 21 and the second portion 23 are relatively large, the overall area of ​​the flexible display screen 2 may be larger than the area of ​​the protective film 3. At this time, most of the structure of the protective film 3 is retracted relative to the flexible display screen 2 to facilitate the installation of the protective film 3. In some other examples, the area of ​​the protective film 3 may also be greater than or equal to the area of ​​the flexible display screen 2, which is not strictly limited in this embodiment.

[0120] See also Figure 5 , Figure 5 yes Figure 4 The structure of the flexible display screen 2 shown is a schematic diagram in some embodiments.

[0121] In some embodiments, on the side of the flexible display screen 2 along the length direction (i.e., the Y direction) of the folding assembly, a recessed area 221 may be formed on the end side of the third part 22. The recessed area 221 is recessed relative to the side of the first part 21 and the side of the second part 23. The width direction of the flexible display screen 2 may be parallel to the X direction, the length direction of the flexible display screen 2 may be parallel to the Y direction, and the thickness direction of the flexible display screen 2 may be parallel to the Z direction. Two recessed areas 221 may be formed on the two sides of the third part 22 in the Y direction. At this time, when the flexible display screen 2 is mounted on the housing device 1 (see Figure 2 ), a gap is formed between the recessed area 221 and the shell device 1, preventing the shell device 1 from directly contacting the end side of the third part 22, thereby facilitating the protection of the end side of the third part 22.

[0122] Exemplarily, in the X direction, the wall surface of the recessed area 221 includes a first wall surface 2211, a bottom wall surface 2212, and a second wall surface 2213. The first wall surface 2211, the bottom wall surface 2212, and the second wall surface 2213 are smoothly connected in sequence, the first wall surface 2211 is also smoothly connected to the side surface of the first part 21, and the second wall surface 2213 is also smoothly connected to the side surface of the second part 23. Exemplarily, the first wall surface 2211 and the second wall surface 2213 can be curved surfaces, and the bottom wall surface 2212 can be a plane.

[0123] Exemplarily, the bottom wall surface 2212 may be parallel to the side surfaces of the first part 21 and the second part 23. On the side surface of the flexible display screen 2 along the length direction (i.e., the Y direction) of the folding assembly, the side walls of the first part 21 and the second part 23 may be coplanar, and the distance between the bottom wall surface 2212 and the side surfaces of the first part 21 and the second part 23 may be less than 0.5 mm, for example, 0.3 mm, which may be specifically set according to requirements, and this embodiment is not strictly limited thereto.

[0124] In some other embodiments, the third portion 22 of the flexible display screen 2 may not form a recessed area 221 , and the end side of the third portion 22 may be flush with the side of the first portion 21 and the side of the second portion 23 .

[0125] Please refer to Figure 4 and Figure 6 , Figure 6 yes Figure 4 The protective film 3 is a schematic structural diagram in some embodiments.

[0126] In some embodiments, the protective film 3 may further include a main body 32. The main body 32 and the protruding portion 31 are fixedly connected, for example, the main body 32 and the protruding portion 31 may be integrally formed. At this time, when the protective film 3 is fixed to the flexible display screen 2, the main body 32 is fixed to the first portion 21, the third portion 22 and the second portion 23 in sequence along the first direction, wherein the first direction may be parallel to the X direction, and the width direction of the protective film 3 is parallel to the X direction.

[0127] Exemplarily, the number of the protrusions 31 can be multiple. For example, every two protrusions 31 can be arranged in a group, and the two protrusions 31 of the same group of protrusions 31 are arranged in the length direction of the folding component and are respectively fixed on the opposite sides of the main body 32. The length direction of the folding component is perpendicular to the first direction, and the protrusions 31 are protruding relative to the main body 32. Among them, the second direction can be parallel to the Y direction. Among them, the number of groups of protrusions 31 may not be limited to one group, and can be set according to the structure of the flexible display 2. This example is not strictly limited to this. In some examples, the two protrusions 31 of the same group of protrusions 31 can be roughly symmetrical structures. In this example, the main body 32 protects the flexible display 2 by fitting most of the structure of the flexible display 2, and the protrusions 31 are set correspondingly to the third part 22 of the flexible display 2 that needs to be bent to protect the end side of the third part 22, so as to better and specifically protect the flexible display 2.

[0128] Exemplarily, the protrusion 31 may include a first side surface 311 and a transition surface 312, and the main body 32 may include a second side surface 321. The first side surface 311 and the second side surface 321 may both be planes and parallel to each other, and the first side surface 311 is smoothly connected to the second side surface 321 through the transition surface 312. At this time, the first side surface 311 is a plane, which can make the protrusion 31 roughly in the shape of a long strip, which is conducive to the uniform shielding of the end side surface of the third part 22 of the flexible display 2 by the protrusion 31, thereby improving the protective performance of the protective film 3; by setting the transition surface 312, the protrusion 31 is easier to shape, and the stress of the protrusion 31 during bending and deformation can be reduced, thereby improving the service life of the protective film 3. In some other examples, the first side surface 311 and the second side surface 321 may also be cylindrical, for example, the first side surface 311 and the second side surface 321 may both extend in a straight line in the X direction and extend in a curve in the Z direction.

[0129] For example, the transition surface 312 may include a first arc surface 3121, a connecting surface 3122, and a second arc surface 3123. The connecting surface 3122 is located between the first arc surface 3121 and the second arc surface 3123, that is, the first arc surface 3121, the connecting surface 3122, and the second arc surface 3123 are arranged in sequence. The first arc surface 3121 may be fixedly connected to the first side surface 311, and the second arc surface 3123 may be fixedly connected to the second side surface 321. The center of the first arc surface 3121 may be located inside the protective film 3, and the center of the second arc surface 3123 may be located outside the protective film 3, so that the bending direction of the first arc surface 3121 is toward the outside of the protective film 3, and the bending direction of the second arc surface 3123 is toward the inside of the protective film 3. In addition, the connecting surface 3122 may be a plane. In this embodiment, by setting the structure of the transition surface 312, the overall curvature of the transition surface 312 is small, the extension of the transition surface 312 is smoother, and the stress distribution of the structure where the transition surface 312 is located is more uniform when the protrusion 31 is bent, and the service life of the protective film 3 is longer. In some other examples, the transition surface 312 may not include the connecting surface 3122, and the first arc surface 3121 and the second arc surface 3123 of the transition surface 312 may be connected.

[0130] In this embodiment, the protruding distance of the protruding portion 31 relative to the main body portion 32 is not strictly limited.

[0131] Please refer to Figure 7 , Fig. 8A and Figure 8B , Figure 7 yes Figure 4 The cross-sectional view of the flexible display screen 2 and the protective film 3 taken along BB is shown. Fig. 8A yes Figure 4 The enlarged image of point C in the middle. Figure 8B yes Figure 4 The structure diagram of the flexible display screen 2 and the protective film 3 shown in another viewing angle.

[0132] In some embodiments, the electronic device 10 may further include a buffer 7. The buffer 7 may be fixedly connected to the end side of the third portion 22 and abut against the bottom surface of the protrusion 31. At this time, the buffer 7 may protect the end side of the third portion 22, so that the external force cannot directly contact the end side of the third portion 22, thereby protecting the flexible display screen 2; the buffer 7 may provide support for the protrusion 31 by abutting against the bottom surface of the protrusion 31, thereby preventing the protrusion 31 from warping or collapsing relative to the flexible display screen 2.

[0133] Exemplarily, the buffer 7 may be fixed to the bottom wall 2212 of the recessed area 221, and the buffer 7 may substantially cover the bottom wall 2212, for example, the buffer 7 may cover more than 90% of the bottom wall 2212, thereby protecting the bottom wall 2212 as a whole. In some other examples, the buffer 7 may also cover a portion or the entire area of ​​the first wall 2211 and / or the second wall 2213, thereby protecting the first wall 2211 and / or the second wall 2213.

[0134] Exemplarily, the buffer member 7 may abut against a portion of the bottom surface of the protrusion 31. The protrusion 31 may partially protrude from the end side of the third portion 22, and the buffer member 7 may support the protrusion 31 relative to the end side of the third portion 22. Since the protective member may have a colloid layer, the protrusion 31 and the buffer member 7 may be bonded via the colloid layer.

[0135] Exemplarily, the material of the buffer 7 can be a colloid. For example, the buffer 7 can be a UV curable glue or a hot melt glue. The buffer 7 can be formed by injecting glue on the end side of the third part 22 before the flexible display screen 2 is installed. Figure 7 As shown, the buffer 7 can be roughly in a triangular prism structure. By setting the material of the buffer 7, the buffer 7 can be bonded to the flexible display screen 2 according to its own material characteristics, without the need for additional adhesives, and is relatively easy to manufacture. It can also ensure that the buffer 7 has good protection performance.

[0136] Exemplarily, the buffer 7 may be a substantially rectangular parallelepiped structure. For example, in the arrangement direction of the first portion 21, the second portion 23, and the third portion 22, i.e., the X direction, the portion of the protrusion 31 protruding relative to the third portion 22 has a first length a, and the buffer 7 has a second length b, which may be greater than or equal to half of the first length a. In this example, by setting the length of the buffer 7, the buffer 7 has a better ability to protect the end side of the third portion 22 and is easy to manufacture.

[0137] In some embodiments, a protrusion distance d of the protrusion 31 relative to the end side surface of the third portion 22 of the flexible display screen 2 may be less than or equal to 0.5 mm.

[0138] For example, in a direction parallel to the flexible display screen 2, the distance between the first side surface 311 of the protrusion 31 of the protective film 3 and the bottom wall surface 2212 of the recessed area 221 of the flexible display screen 2 is the protrusion distance d, and the protrusion distance d can be in the range of 0.1 mm to 0.2 mm.

[0139] In this embodiment, by reasonably setting the protrusion distance of the protrusion 31 relative to the third portion 22 of the flexible display screen 2, the protrusion 31 can protect the end side of the third portion 22 of the flexible display screen 2, and the protrusion 31 is not easy to be lifted up and is not easy to be in contact with the housing device 1 (see Figure 2 ) contact, thereby improving the service life of the protective film 3.

[0140] In some embodiments, in a direction perpendicular to the flexible display screen 2, i.e., in the Z direction, the side surface of the protrusion 31 intersects with the first wall surface 2211 and the second wall surface 2213, and the protrusion 31 covers the bottom wall surface 2212. Figure 8B As shown, a portion of the transition surface 312 corresponding to the first wall 2211 is suspended outside the first wall 2211, and the remaining portion extends to the inside of the first wall 2211 and is located above the third portion 22, that is, the transition surface 312 intersects with the first wall 2211. A portion of the transition surface 312 corresponding to the second wall 2213 is suspended outside the second wall 2213, and the remaining portion extends to the inside of the second wall 2213 and is located above the third portion 22, that is, the transition surface 312 intersects with the second wall 2213. At this time, the protrusion 31 of the protective film 3 can at least cover the entire area of ​​the bottom wall 2212 of the recessed area 221 of the flexible display 2 and partial areas of the first wall 2211 and the second wall 2213, so that the covered part of the end side of the third part 22 cannot be directly exposed to the external space, thereby protecting the bottom wall 2212 and partial areas of the first wall 2211 and the second wall 2213, and increasing the protection area of ​​the protrusion 31 for the third part 22.

[0141] Exemplarily, in a direction perpendicular to the flexible display screen 2, i.e., the Z direction, a transition surface 312 of the protrusion 31 may intersect with the first wall surface 2211, another transition surface 312 of the protrusion 31 may intersect with the second wall surface 2213, and the first side surface 311 of the protrusion 31 may be parallel to the bottom wall surface 2212.

[0142] See also Fig. 9 , Fig. 9 yes Figure 1 The structure of the electronic device 10 is shown in another perspective.

[0143] In some embodiments, in the arrangement direction of the first portion 21, the second portion 23 and the third portion 22, i.e., the X direction, the ratio of the length e of the protrusion 31 to the width f of the arrangement area of ​​the main axis 123, the first support plate 122 and the second support plate 124 is greater than or equal to 1.

[0144] The arrangement area of ​​the main shaft 123, the first support plate 122 and the second support plate 124 refers to the area occupied by the main shaft 123, the first support plate 122 and the second support plate 124 when the electronic device is in a flat state, and the width of this area is the width f.

[0145] The arrangement area of ​​the main shaft 123, the first support plate 122 and the second support plate 124 forms the main deformation area of ​​the housing device 1. The large end 1231 of the main shaft 123, the small end 1221 of the first support plate 122 and the small end 1221 of the second support plate 124 can be located between the first housing 11 and the second housing 13, and exposed relative to the first housing 11, the second housing 13 and the protective film 3. The small end 1221 of the first support plate 122 and the small end 1221 of the second support plate 124 can be located on both sides of the main shaft 123, and during the unfolding and folding process of the electronic device 10, the small end 1221 of the first support plate 122 and the small end 1221 of the second support plate 124 can rotate relative to the large end 1231 of the main shaft 123.

[0146] Correspondingly, the third part 22 of the flexible display screen 2 needs to cover the deformation area so that the flexible display screen 2 can deform along with the deformation of the housing device 1. The width of the third part 22 can be equal to or greater than the width of the deformation area, and the end side of the third part 22 can be designed to be retracted or avoided, so that a gap is required between the end side of the third part 22 and the ends of the main shaft 123, the first support plate 122 and the second support plate 124, so as to reduce the contact between the third part 22 and the main shaft 123, the first support plate 122 and the second support plate 124, thereby reducing the damage to the third part 22 and improving the service life of the flexible display screen 2.

[0147] Exemplarily, the distance between the bottom wall 2212 of the third portion 22 and the large end 1231 of the main shaft 123, the small end 1221 of the first support plate 122 or the small end 1221 of the second support plate 124 may be less than 0.5 mm, which is not strictly limited in this example.

[0148] At this time, the protrusion 31 of the protective film 3 needs to be adaptively designed according to the third part 22, and the protrusion 31 needs to cover the part of the end side of the third part 22 within the arrangement area of ​​the main shaft 123, the first support plate 122 and the second support plate 124. Therefore, the length of the protrusion 31 of the protective film 3 is at least greater than or equal to the width of the arrangement area of ​​the main shaft 123, the first support plate 122 and the second support plate 124.

[0149] In this embodiment, by setting the length of the protrusion 31, the arrangement of the shell device 1, the flexible display screen 2 and the protective film 3 is made more reasonable, the layout is more compact and beautiful, and the service life of the flexible display screen 2 is improved, thereby improving the service life of the electronic device 10.

When the electronic device 10 is folded to a closed state, the first portion 21, the second portion 23 and the third portion 22 of the flexible display screen 2 are all facing the inside of the electronic device 10.

[0154] In addition, the folding assembly 12 may include a first connecting portion, a first support plate, a main shaft, a second support plate and a second connecting portion. The first connecting portion, the first support plate, the main shaft, the second support plate and the second connecting portion are arranged in sequence. The first connecting portion, the first support plate and the main shaft may be connected by a first connecting mechanism so that the three can move relative to each other. The main shaft, the second support plate and the second connecting portion may be connected by a second connecting mechanism so that the three can move relative to each other. Among them, the first support plate and the second support plate may be of hidden design, and the main shaft may be exposed relative to the first shell and the second shell. In some other embodiments, the folding assembly may not be provided with the first support plate and the second support plate.

[0155] The following mainly uses the electronic device 10 as a tri-fold folding mobile phone for exemplary description.

Fig.11 The electronic device 10 shown may include Figure 1 Most of the technical features of the electronic device 10 shown are the same as those of the two devices. This embodiment will not repeat them in detail, and the differences between the two devices will be mainly described below. Fig.11 The electronic device 10 is shown with Figure 1 The main difference between the electronic devices 10 shown is the number of folders 12 .

[0157] In some embodiments, Fig.11 The electronic device 10 shown may be a tri-fold foldable mobile phone having two outer-folding foldable components 12 .

[0158] Exemplarily, the housing device 1 of the electronic device 10 includes a first housing 11, a second housing 13, a third housing 14 and two folding components 12. One folding component 12 connects the first housing 11 and the second housing 13, and the other folding component 12 connects the second housing 13 and the third housing 14.

[0159] Exemplarily, the flexible display screen 2 of the electronic device 10 may include a first part 21, a second part 23, a third part 22, a fourth part 26 and a fifth part 27. The first part 21, the third part 22, the second part 23, the fifth part 27 and the fourth part 26 are connected in sequence. The flexible display screen 2 can be installed corresponding to the housing device 1. For example, the first part 21 corresponds to the first housing 11, the second part 23 corresponds to the second housing 13, the third part 22 corresponds to the folding component 12 between the first housing 11 and the second housing 13, the fourth part 26 corresponds to the third housing 14, and the fifth part 27 corresponds to the folding component 12 between the second housing 13 and the third housing 14.

[0160] For example, the protective film 3 may have two groups of protrusions 31, and the two groups of protrusions 31 are correspondingly located at the two folding components 12. For details, please refer to Figure 1 Alternatively, the protective film 3 may also have a group of protrusions 31, and a group of protrusions 31 is correspondingly located at one of the folding components 12. This example does not strictly limit the number of groups of protrusions 31 of the protective film 3.

[0161] In this embodiment, when the electronic device 10 is in the folded state, multiple parts of the flexible display screen 2 may face the outside of the electronic device 10 , which is not strictly limited in this embodiment.

[0162] See also Fig.12 , Fig.12 1 is a partial view of another electronic device 10 provided by the present application. Fig.12The electronic device 10 shown may include Fig.11 Most of the technical features of the electronic device 10 shown are the same as those of the two devices. This embodiment will not repeat them in detail, and the differences between the two devices will be mainly described below.

[0163] In some embodiments, Fig.12 The electronic device 10 shown may be a tri-fold foldable mobile phone having two inwardly folding folding mechanisms. Fig.12 The electronic device 10 is shown with Fig.11 The general structure and connection method of the electronic device 10 shown are basically the same, and the main difference lies in the different folding methods of the folding assembly 12.

[0164] For example, the two folding components 12 of the electronic device 10 are both inward-folding folding components 12. The inward-folding folding components 12 can refer to Fig.10 The relevant schemes in the embodiments are not described in detail in this embodiment.

[0165] For example, the flexible display screen 2 and the protective film 3 of the electronic device 10 can refer to Fig.11 The relevant description of the embodiment will not be repeated in this embodiment.

[0166] See also Fig.13 , Fig.13 1 is a partial view of another electronic device 10 provided by the present application. Fig.13 The electronic device 10 shown may include Fig.11 Most of the technical features of the electronic device 10 shown are the same as those of the two devices. This embodiment will not repeat them in detail, and the differences between the two devices will be mainly described below.

[0167] In some embodiments, Fig.13 The electronic device 10 shown may be a tri-fold foldable mobile phone having an inner folding mechanism and an outer folding mechanism. Fig.13 The electronic device 10 is shown with Fig.11 The general structure and connection method of the electronic device 10 shown are basically the same, and the main difference lies in the different folding methods of the folding assembly 12.

[0168] For example, of the two folding components 12 of the electronic device 10, the folding component 12 between the first housing 11 and the second housing 13 is of an inner folding type, and the folding component 12 between the second housing 13 and the third housing 14 is of an outer folding type. Fig.10 For the related schemes in the embodiments, the outward folding assembly 12 can refer to Figure 1 The related schemes in the embodiment will not be described in detail in this embodiment.

[0169] For example, the flexible display screen 2 and the protective film 3 of the electronic device 10 can refer to Fig.11The relevant description of the embodiment will not be repeated in this embodiment.

[0170] See also Fig.14 and Fig.15 , Fig.14 is a schematic structural diagram of a protective film group 20 provided in the present application, Fig.15 yes Fig.14 The protective film assembly 20 is a partial cross-sectional view taken along line DD in some embodiments.

[0171] In some embodiments, the protective film set 20 includes a protective film 3 and a release film 201. The protective film 3 is used to be fixed to the flexible display screen 2 of the electronic device 10, and the release film 201 is attached to the protective film 3. In this embodiment, the release film 201 can protect the protective film 3, which is convenient for the storage and transportation of the protective film set 20.

[0172] The release film 201 can be attached to the protective film 3 or can be torn off from the protective film 3. When the release film 201 is attached to the protective film 3, the protective film 3 can be protected to prevent the protective film 3 from being damaged. When the protective film 3 needs to be used, the release film 201 can be torn off from the protective film 3 and the protective film 3 can be attached to the flexible display screen 2 of the electronic device 10 (see Figure 2 ), used to protect the flexible display screen 2. The application of the protective film 3 in the electronic device 10 can refer to the above Figures 1 to 13 The corresponding embodiments are not described in detail in this embodiment.

[0173] In some examples, the protection film 3 may include a base layer 33 and a colloid layer 34 .

[0174] For example, the base layer 33 and the colloid layer 34 can be fixedly connected. The colloid layer 34 can be made of OCA (Optically Clear Adhesive) glue, and this example does not strictly limit the material of the colloid layer 34. Figure 2 When the protective film 3 is fixed to the electronic device 10 (see FIG. 1 ), the protective film 3 can be connected to the flexible display screen 2 through the colloid layer 34. Since the colloid layer 34 of the protective film 3 can be torn off from the flexible display screen 2, it is convenient to remove the protective film 3 from the flexible display screen 2 and replace the protective film 3, thereby extending the service life of the electronic device 10. Figure 2 ), the base layer 33 can face the outside of the electronic device 10, the surface of the base layer 33 is in contact with the external environment, and is used to interact with the user and protect the flexible display 2, and the colloid layer 34 can be located between the flexible display 2 and the base layer 33, and is used to connect the flexible display 2 and the base layer 33.

[0175] Exemplarily, the release film 201 may have one layer, and the release film 201 may be bonded to the colloid layer 34. The release film 201 may be torn off from the colloid layer 34. The release film 201 may cover the colloid layer 34, thereby protecting the colloid layer 34. In some other examples, the release film 201 may also have two layers, one of which is attached to the colloid layer 34 and the other is attached to the base layer 33, thereby providing double-sided protection for the protective film 3.

[0176] In some examples, the protective film 3 may include a main body 32 and a protruding portion 31, wherein the protruding portion 31 is protruding relative to the side of the main body 32. The main body 32 and the protruding portion 31 are fixedly connected. In this example, when the protective film 3 is applied to the flexible display screen 2 (see Figure 2 ), the protruding portion 31 of the protective film 3 can partially shield the flexible display screen 2, thereby providing more targeted protection and improving the protective performance of the protective film 3.

[0177] Exemplarily, the number of the protrusions 31 may be multiple. For example, every two protrusions 31 may be arranged in a group, and the two protrusions 31 of the same group of protrusions 31 are arranged in the second direction and are respectively fixed on opposite sides of the main body 32, and the protrusions 31 are arranged to protrude relative to the main body 32. The second direction may be the length direction of the protective film 3, the second direction may be parallel to the Y direction, and the width direction of the protective film 3 may be parallel to the X direction. Fig.14 In the embodiment, the protective film 3 is provided with a group of protrusions 31 as an example. In other embodiments, the number of groups of protrusions 31 is not limited to one group, and can be provided according to the structure of the flexible display screen 2. For example, two groups or three groups can be provided, and this example is not strictly limited to this. In some examples, two protrusions 31 of the same group of protrusions 31 can be substantially symmetrical structures.

[0178] In this example, the main body 32 is used to adhere to the flexible display screen 2 (such as Figure 2 The flexible display screen 2 is protected by arranging the protrusions 31 in groups, so that the protrusions 31 and the portions of the flexible display screen 2 that need to be bent are arranged correspondingly, so as to protect the end sides of the portions of the flexible display screen 2 that need to be bent, thereby better and specifically protecting the flexible display screen 2.

[0179] Exemplarily, the protrusion 31 may include a first side surface 311 and a transition surface 312, and the main body 32 may include a second side surface 321. Among them, the first side surface 311 and the second side surface 321 may both be planes and parallel to each other, and the first side surface 311 is smoothly connected to the second side surface 321 through the transition surface 312. In some other examples, the first side surface 311 and the second side surface 321 may also be straight curved surfaces in the X direction. At this time, the first side surface 311 is a plane, which can make the protrusion 31 roughly in the shape of a long strip, which is conducive to the uniform shielding of the end side surface of the third part 22 of the flexible display screen 2 by the protrusion 31, thereby improving the protective performance of the protective film 3; by setting the transition surface 312, the protrusion 31 is easier to form, and the stress of the protrusion 31 during bending and deformation can be reduced, thereby improving the service life of the protective film 3.

[0180] For example, the transition surface 312 may include a first arc surface 3121, a connecting surface 3122 and a second arc surface 3123. The first arc surface 3121, the connecting surface 3122 and the second arc surface 3123 are fixedly connected in sequence, the first arc surface 3121 is fixedly connected to the first side surface 311, and the second arc surface 3123 is fixedly connected to the second side surface 321. The center of the first arc surface 3121 may be located inside the protective film 3, and the center of the second arc surface 3123 may be located outside the protective film 3, so that the bending direction of the first arc surface 3121 is toward the outside of the protective film 3, and the bending direction of the second arc surface 3123 is toward the inside of the protective film 3. In addition, the connecting surface 3122 may be a plane. In this embodiment, by setting the structure of the transition surface 312, the overall curvature of the transition surface 312 is small, the extension of the transition surface 312 is smoother, and the stress distribution of the structure where the transition surface 312 is located when the protrusion 31 is bent is more uniform, and the service life of the protective film 3 is longer. In some other examples, the transition surface 312 may not include the connecting surface 3122 , and the first arc surface 3121 and the second arc surface 3123 of the transition surface 312 may be connected.

[0181] In some examples, the shape of the release film 201 may be substantially consistent with the shape of the protective film 3, so as to fully cover the protective film 3. The shape of the release film 201 is not strictly limited in this example.
