Description

electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202411017258.2, filed on July 27, 2024, entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal equipment technology, and more particularly to an electronic device. Background Technology

[0003] Foldable electronic devices include a flexible display screen and a housing device for supporting the flexible display screen. The housing device folds or unfolds relative to each other through deformation, thereby causing the flexible display screen to fold or unfold, thus realizing the folding and unfolding of the foldable electronic device. When the foldable electronic device is in the closed state, it occupies a relatively small space; when it is in the unfolded state, it can display a relatively large screen.

[0004] In the existing technology, there are tri-fold foldable electronic devices, which can achieve a small size by folding twice. However, improving the reliability of tri-fold phones during use is a problem that needs to be solved. Summary of the Invention

[0005] The purpose of this application is to provide an electronic device.

[0006] The electronic device provided by an embodiment of the present application includes a housing device and a flexible display screen; the housing device includes a first housing, a second housing, a third housing, a first rotating shaft, and a second rotating shaft. The first rotating shaft connects the first housing and the second housing, and the second rotating shaft connects the second housing and the third housing; the first housing and the second housing can be relatively folded and opened through the first rotating shaft, and the second housing and the third housing can be relatively folded and opened through the second rotating shaft; the first housing includes a first middle plate and a first frame, the first frame is fixedly connected to the first middle plate, the second housing includes a second middle plate and a second frame, the second frame is fixedly connected to the second middle plate, the third housing includes a third middle plate and a third frame, and the third frame is fixedly connected to the third middle plate; the flexible display screen includes a first part, a first bending part, a second part, a second bending part, and a third part connected in sequence; the first part is installed on the first middle plate and is located inside the first frame; the second part is installed on the second middle plate and is located inside the second frame; the third part is installed on the third middle plate and is located inside the third frame; when the electronic device is in an open state, the first housing, the second housing, and the third housing are arranged in a first direction, and the first part, the first bending part, the second part, the second bending part, and the third part are in a flat plate structure. When the electronic device is in a closed state, the third housing is located between the first housing and the second housing, the first bending part and the second bending part are respectively in a bent structure, and the second part and the third part are arranged facing each other; when the first housing is folded relative to the second housing to a first angle and the third housing is folded relative to the second housing to a second angle, the third frame abuts against the first frame and is relatively and spaced apart from the first part.

[0007] Exemplarily, the first angle a satisfies 0° < a < 180°, the second angle b satisfies 0° < c < 180°. In addition, there may be a third angle c between the first housing and the third housing, and the first angle c satisfies 0° < c < 180°, and a + b + c = 180°. It can be understood that the first angle a and the second angle b indicate that the first housing, the second housing, and the third housing of the electronic device can be folded to a certain extent so that the first housing and the third housing can contact each other, rather than a limitation on the form or structure of the electronic device.

[0008] Exemplarily, the third housing may be located between the first housing and the second housing; and the first housing and the third housing can respectively rotate relative to the second housing. Thus, when the first housing and the second housing are folded to a first angle a and the second housing and the third housing are folded to a second angle b; that is, both the first housing and the third housing are folded relative to the second housing, and the folding degree of the second housing and the third housing is greater, there are some angle combinations of the first angle a and the second angle b that make the third housing and the first housing approach and contact each other, so that the first housing, the second housing, and the third housing contact each other to form a triangular structure.

[0009] For example, when the first angle 'a' is greater than the second angle 'b', the degree of bending of the second and third shells is greater than that of the first and second shells, making it easier for the third shell to come into contact with the first shell. In addition, when the length of the third shell is less than that of the first shell, there are some combinations of the first angle 'a' and the second angle 'b', where the first angle 'a' is less than the second angle 'b' and the degree of bending of the second and third shells is greater than that of the first and second shells, thereby enabling the third shell to come into contact with the first shell.

[0010] For example, the third border being relative to the first part can mean that, in a direction perpendicular to the first part, the projection of the portion of the first part that is exposed above the first border coincides with the projection of the third border.

[0011] In this embodiment, since the third frame can abut against the first frame, and there is a gap between the third frame and the first part in the direction perpendicular to the first part, the first frame provides support to the third frame, while the third frame cannot contact the first part. Therefore, during the use of the electronic device, such as when folding the electronic device or when the electronic device is impacted, the third frame will not impact the first part of the flexible display screen, thereby improving the service life of the flexible display screen and thus improving the service life of the electronic device.

[0012] In some embodiments, the first frame may include a first side strip, a second side strip, and a third side strip connected in sequence, with the first side strip and the second side strip of the first frame being arranged opposite to each other; the third frame may include a first side strip, a second side strip, and a third side strip connected in sequence, with the first side strip and the second side strip of the third frame being arranged opposite to each other; the second side strip of the third frame has a first side surface located on the side opposite to the second pivot, and the highest point of the second side strip of the third frame is located on the first side surface along the length direction of the first side strip of the third frame.

[0013] The first edge strip of the third frame includes a first end face facing away from the second pivot. In the length direction of the first edge strip of the third frame, the highest point of the first edge strip of the third frame is located on the first end face, and the height of the first end face is higher than or equal to the height of the first side face; and / or, the third edge strip of the third frame has a second end face facing away from the second pivot. In the length direction of the third edge strip of the third frame, the highest point of the third edge strip of the third frame is located on the second end face, and the height of the second end face is higher than or equal to the height of the first side face.

[0014] In this embodiment, the distance between the first end face and the first edge strip of the first frame is always less than the distance between the first side face and the first part. Therefore, when the electronic device is folded from the open state to the first housing folded relative to the second housing at a first angle 'a', and the third housing folded relative to the second housing at a second angle 'b', the first end face will first abut against the first edge strip of the first frame, while simultaneously ensuring that the first side face and the first part are spaced apart in the direction perpendicular to the first part, thus preventing the first part from being collided with. In addition, this embodiment has fewer restrictions on the first side face and the first end face, which is beneficial for designing the surface shape of the first side face and the first end face according to requirements.

[0015] Similarly, by setting a second end face, when the electronic device folds from the open state to the point where the first housing is folded relative to the second housing at a first angle 'a', and the third housing is folded relative to the second housing at a second angle 'b', the second end face will first abut against the third edge strip of the first frame, while simultaneously ensuring that the first side and the first part are spaced apart in the direction perpendicular to the first part, thus preventing the first part from being collided with. Furthermore, since both the first and second end faces abut against the first frame, it helps to balance the forces on the third frame, preventing the third frame from twisting, reducing the probability of the third frame colliding with the first part, and improving the reliability of the electronic device.

[0016] In some implementations, when the electronic device is in the open state, the surface of the first frame is higher than or equal to the surface of the first portion in a direction perpendicular to the flexible display screen.

[0017] In this embodiment, a portion of the first part is surrounded by a first frame, and a portion of the third part is surrounded by a third frame, thereby facilitating the protection of the flexible display screen by the first and third frames.

[0018] In the direction perpendicular to the first part, the first part is flush with or recessed relative to the first frame. When the first frame comes into contact with the third frame, it helps to increase the distance between the first side and the first part, thereby avoiding collision between the third frame and the first part to a greater extent and improving the reliability of the electronic device.

[0019] In some implementations, the first side surface is flush with the first end surface, and the first side surface is flush with the second end surface.

[0020] In this embodiment, the first side surface and the first end surface are flush, making the surface of the third frame smoother and the shape simpler. The first side surface and the first end surface can be formed simultaneously, which facilitates the production of the third frame.

[0021] In some embodiments, the first edge strip of the third frame has a second side surface located on the side of the third edge strip away from the third frame, and the second side surface intersects with the first end face.

[0022] In this embodiment, the first and second sides can be directly connected, and the first and third sides can be directly connected, which is equivalent to not chamfering or rounding the corners of the third frame. When the third frame contacts the first frame, the first end face can abut against the first edge strip of the first frame, and the second end face can abut against the third edge strip of the first frame. Since there is no transition surface between the first end face and the second side, and no transition surface between the second end face and the third side, the areas of the first and second end faces can be larger. This is beneficial to have a larger contact area or contact size between the first end face and the first frame, as well as between the second end face and the first frame, thereby reducing the impact on the structure of the first and third frames when they collide.

[0023] In some embodiments, the first edge strip of the third frame has a second side surface and a first transition surface, the second side surface being located on the side of the third edge strip away from the third frame, and the first transition surface connecting the second side surface and the first end surface.

[0024] In this embodiment, the first end face and the second side face are connected by a first transition surface, making the transition between the first end face and the second side face smoother. This avoids the sharp corners of the first edge strip of the third frame, which helps to reduce the stress when the first end face comes into contact with other objects. This helps to protect the third frame, improve the service life of the housing device and electronic equipment, and also improve the user's handling experience.

[0025] In some implementations, the first transition surface is a plane; or, the first transition surface is a curved surface.

[0026] For example, the dimension of the first transition surface along the length of the first edge strip of the third frame can be larger than the dimension of the second edge strip of the third frame along the length of the first edge strip of the third frame. Conversely, the dimension of the first transition surface along the length of the second edge strip of the third frame can be smaller than the dimension of the first edge strip of the third frame along the length of the second edge strip of the third frame. This allows the first transition surface to have a larger dimension, thereby facilitating a smooth transition between the first end face and the second side face.

[0027] In this embodiment, the first transition surface is a plane, which simplifies the structure of the first edge strip of the third frame and facilitates molding. The first transition surface is a curved surface, which makes the surface of the first edge strip of the third frame smoother.

[0028] In some embodiments, the first edge strip of the first frame has a first top surface, which is perpendicular to the thickness direction of the first portion and is located on the same side of the first middle plate as the first portion; the first top surface is a plane.

[0029] In this embodiment, the shape of the first top surface is more compatible with the shape of the first end surface. When the first end surface abuts against the surface of the first edge strip of the first frame, that is, when the first end surface abuts against the first top surface, the first top surface can have a larger contact area with the first end surface. On the one hand, this can improve the reliability of the abutment between the first end surface and the first top surface, and on the other hand, it can reduce the abutment stress of the first edge strip of the first frame and the first edge strip of the third frame, thereby reducing the collision damage to both.

[0030] In some embodiments, when the first housing and the second housing are folded relative to each other and the second housing and the first housing are opened relative to each other, the first housing is located away from the edge of the second housing and on the side of the center of the second pivot that is away from the first pivot.

[0031] For example, the width of the first housing can be greater than the width of the second housing.

[0032] In this embodiment, since the first housing is wider and its end is close to the second pivot, the third housing can directly abut against the end of the first housing, or the third housing can abut against the end of the first housing after rotating a small angle (degrees to degrees), so that the third housing cannot continue to fold relative to the second housing, thereby reducing damage to the housing device.

[0033] In some embodiments, when the first housing and the second housing are folded relative to each other and the second housing and the first housing are opened relative to each other, the first housing is located away from the edge of the second housing and on the side of the second pivot away from the first pivot.

[0034] In this embodiment, since the first housing is wider and its end is close to the second pivot, the first housing can directly abut against the third housing, preventing the second and third housings from rotating relative to each other (i.e., they cannot be folded), thereby avoiding excessive force on the second pivot and thus improving the reliability of the electronic device.

[0035] In some embodiments, the first housing further includes a protrusion fixed to the first middle plate, the protrusion being located on the same side of the first middle plate as the first portion, and the protrusion being located on the side of the first frame away from the first portion; the protrusion protrudes relative to the first middle plate, and the protrusion height of the protrusion is higher than that of the first frame.

[0036] For example, the protrusion may have a light-transmitting hole. This light-transmitting hole may be located on the top surface of the protrusion. The protrusion can be used to mount a camera, and the light-transmitting hole allows light to enter the camera for image formation. There can be multiple light-transmitting holes to facilitate imaging through different lenses.

[0037] For example, the protrusion may also have button holes. These button holes may be located on the side of the protrusion facing away from the first frame, but are not strictly limited to this. There may be multiple button holes. The button holes are used to accommodate buttons, such as volume buttons, power buttons, etc.

[0038] In this embodiment, the protrusion extends beyond the first middle plate, resulting in a higher height for the first housing. This facilitates the installation of larger components inside the protrusion. The protrusion also helps to differentiate the structures of the first and third housings, thereby preventing user misoperation.

[0039] In some embodiments, when the electronic device is in a closed state, in the arrangement direction of the first housing, the second housing, and the third housing, the top surface of the protrusion is higher than the third housing, and the top surface of the protrusion and the first part are located on the same side of the first middle plate.

[0040] In this embodiment, the protrusion protects the sides of the third housing and part of the sides of the second housing, preventing the sides of the third housing from being collided with by other objects and reducing the probability of the second housing being accidentally opened. Furthermore, the protrusion, the first housing, and the second housing surround the third housing, thereby jointly protecting it and improving the reliability of the electronic device.

[0041] In some embodiments, when the first housing and the second housing have a first angle, the second housing and the third housing have a second angle, and the first angle is less than the second angle, the protrusion abuts against the third frame.

[0042] In this embodiment, the bending degree of the first housing and the second housing is greater than that of the second housing and the third housing, and the length of the protrusion is longer, which is beneficial for the protrusion to abut against the third frame, thereby avoiding collision with the third part, thus helping to protect the third part and improve the service life of the electronic device.

[0043] In some embodiments, the top surface of the protrusion is a plane, and in the arrangement direction of the first housing, the second housing, and the third housing, the highest point of the protrusion is located on the top surface of the protrusion; when the protrusion contacts the third frame, a portion of the top surface of the protrusion abuts against the first edge strip of the third frame, and a portion of the top surface of the protrusion abuts against the third edge strip of the third frame.

[0044] In this embodiment, since the top surface of the protrusion can simultaneously abut against the first edge strip of the third frame and the third edge strip of the third frame, the length of the protrusion is relatively long, the abutment between the protrusion and the third frame is relatively stable, and the top surface of the protrusion is flat, which helps to prevent other structures on the protrusion from impacting the third part, thus providing more reliable protection for the flexible display screen.

[0045] In some embodiments, a camera is mounted on the protrusion, with the camera protruding from the top surface of the protrusion.

[0046] In this embodiment, the camera is mounted on the protrusion, which allows for the installation of a larger or more numerous camera, thereby enhancing the camera's performance. Attached Figure Description

[0063] The embodiments of this application are described below with reference to the accompanying drawings.

[0064] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Multiple" refers to at least two.

[0065] The directional terms mentioned in the embodiments of this application, such as "upper", "lower", "inner", "outer", "top", "bottom", "side", etc., are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0066] In the embodiments of this application, the relative positional relationships mentioned, such as parallel, perpendicular, and aligned, are defined in relation to the current technological level, rather than being absolutely strict. Slight deviations are permissible; approximations of parallelism, perpendicularity, or alignment are all acceptable. For example, "A and B are parallel" means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 and 10 degrees. Similarly, "A and B are perpendicular" means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 and 100 degrees.

[0067] In the embodiments of this application, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0068] Please refer to Figures 1, 2 and 3. Figure 1 is a structural schematic diagram of an electronic device 100 in an open state according to an embodiment of this application. Figure 2 is a structural schematic diagram of the electronic device 100 in an intermediate state as shown in Figure 1. Figure 3 is a structural schematic diagram of the electronic device 100 in a closed state as shown in Figure 1.

[0069] In some embodiments, the electronic device 100 is a foldable device, having an open state and a closed state. For example, the electronic device 100 includes a housing device 10 and a flexible display screen 20, the flexible display screen 20 being mounted on the housing device 10. As shown in FIG1, the housing device 10 can be unfolded to the open state; as shown in FIG3, the housing device 10 can also be folded to the closed state; as shown in FIG2, the housing device 10 can also be unfolded or folded to an intermediate state, the intermediate state being any state between the open and closed states. The flexible display screen 20 is a bendable structure, and the flexible display screen 20 moves with the housing device 10. The housing device 10 can drive the flexible display screen 20 to unfold or fold, so that the electronic device 100 can unfold or fold to the open state, closed state, or intermediate state. When the electronic device 100 is in the closed state, the flexible display screen 20 is located inside the housing device 10, and the electronic device 100 is an inward-folding device.

[0070] In this embodiment, when the electronic device 100 is in the open state, the flexible display screen 20 unfolds and can display in full screen, giving the electronic device 100 a larger display area to improve the user's viewing and operating experience. When the electronic device 100 is in the closed state, its planar dimensions are smaller, making it easier for users to carry and store.

[0071] In some embodiments, the electronic device 100 may further include multiple components (not shown in the figures), which are mounted inside the housing device 10. These components may include, for example, a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc. The electronic device 100 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. The various components may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application-specific integrated circuits.

[0072] It is understood that when a user holds the electronic device 100, the position of the earpiece module of the electronic device 100 can be defined as the top of the electronic device 100, the position of the microphone module of the electronic device 100 can be defined as the bottom of the electronic device 100, and the two sides of the electronic device 100 held by the user's left and right hands can be defined as the left and right sides of the electronic device 100. In some embodiments, the electronic device 100 can be folded horizontally. In other embodiments, the electronic device 100 can be folded vertically.

[0073] Please refer to Figures 1 to 5. Figure 4 is a cross-sectional view taken along point AA in Figure 3, and Figure 5 is an exploded structural diagram of the electronic device 100 shown in Figure 1.

[0074] In some embodiments, the housing device 10 includes a first housing 1, a second housing 2, a third housing 3, a first rotating shaft 4, and a second rotating shaft 5. The first rotating shaft 4 connects the first housing 1 and the second housing 2, and the second rotating shaft 5 connects the second housing 2 and the third housing 3.

[0075] The first pivot 4 can deform so that the first housing 1 and the second housing 2 can be folded relative to each other, and the second pivot 5 can deform so that the second housing 2 and the third housing 3 can be folded relative to each other, so that the first housing 1, the second housing 2 and the third housing 3 can be unfolded relative to each other to an open state or folded relative to each other to a closed state, and can also be unfolded relative to each other or folded relative to each other to an intermediate state.

[0076] It should be understood that when the electronic device 100 is in the open state, the flexible display screen 20, the housing device 10, and each component of the housing device 10 are correspondingly in the open state; when the electronic device 100 is in the closed state, the flexible display screen 20, the housing device 10, and each component of the housing device 10 are correspondingly in the closed state; when the electronic device 100 is in the intermediate state, the flexible display screen 20, the housing device 10, and each component of the housing device 10 are correspondingly in the intermediate state.

[0077] As shown in Figure 1, when the electronic device 100 is in the open state, the first housing 1, the second housing 2, and the third housing 3 can be arranged along a first direction. This first direction can be parallel to the X-direction.

[0078] The angle between the first housing 1 and the second housing 2 can be approximately 180°, and the angle between the second housing 2 and the third housing 3 can also be approximately 180°. When the first housing 1, the second housing 2, and the third housing 3 are flattened, the flexible display screen 20 also correspondingly flattens out. At this time, the first housing 1, the second housing 2, and the third housing 3 can be spliced ​​together. The splicing of the first housing 1, the second housing 2, and the third housing 3 includes situations where the three housings abut against each other, and situations where there are small gaps between adjacent two housings. In this embodiment, by splicing the first housing 1, the second housing 2, and the third housing 3, the unfolding action of the housing device 10 can be stopped, preventing the housing device 10 from over-folding during unfolding, thereby reducing the stress on the flexible display screen 20 and improving the reliability of the flexible display screen 20 and the electronic device 100.

[0079] In some other embodiments, when the electronic device 100 is in the open state, the angle between the first housing 1 and the second housing 2 may deviate slightly from 180°, for example, by 165°, 177°, or 185°, and in this case, the first housing 1 and the second housing 2 are also considered to be flat. Similarly, the angle between the second housing 2 and the third housing 3 may also deviate slightly from 180°, for example, by 165°, 177°, or 185°, and in this case, the second housing 2 and the third housing 3 are also considered to be flat. The included angle between the first housing 1 and the second housing 2 is defined as the angle between the upper side of the first housing 1 and the upper side of the second housing 2; the included angle between the second housing 2 and the third housing 3 is defined as the angle between the upper side of the first housing 1 and the upper side of the second housing 2.

[0080] As shown in Figure 3, when the electronic device 100 is in a closed state, the first housing 1, the third housing 3, and the second housing 2 are arranged along a second direction, with the third housing 3 located between the first housing 1 and the second housing 2. The second direction can be parallel to the Z-direction.

[0081] The angle between the first housing 1 and the second housing 2 can be approximately 0°, and the first housing 1 and the second housing 2 are folded into a closed state; the angle between the second housing 2 and the third housing 3 can also be approximately 0°, and the second housing 2 and the third housing 3 are folded into a closed state; the flexible display screen 20 presents a folded shape. For example, when the second housing 2 and the third housing 3 are in the closed state, they can contact each other to achieve positioning; when the first housing 1 and the second housing 2 are folded into a closed state, the third housing 3 is placed between them, and the first housing 1 and the third housing 3 contact each other to achieve positioning. In some other embodiments, when the second housing 2 and the third housing 3 are in the closed state, they can also be close to each other, and there is a small gap between them; when the first housing 1 and the second housing 2 are in the closed state, there is a gap between them, and the third housing is located in this gap; there is a gap between the first housing 1 and the third housing 3, which is not strictly limited in this application. When there is a small gap between the second housing 2 and the first housing 1 and the second housing 2, some foreign objects (such as nails, paper clips, glass shards, etc.) outside the electronic device 100 will not enter between the first housing 1, the second housing 2 and the third housing 3 through the gap, so as to avoid foreign objects damaging the flexible display screen 20, thereby improving the reliability of the electronic device 100.

[0082] It is understood that the first housing 1, the second housing 2, and the third housing 3 are housing components used to install and fix other components of the electronic device 100, and have diverse structures. The embodiments of this application provide exemplary descriptions of some structures of the first housing 1, the second housing 2, and the third housing 3, and simplified schematic diagrams are also provided in the accompanying drawings.

[0083] In some embodiments, referring to Figures 1 and 4, the flexible display screen 20 may include a first portion 201, a first bent portion 202, a second portion 203, a second bent portion 204, and a third portion 205 arranged sequentially. The first bent portion 202 is fixedly connected to the first portion 201 and the second portion 203, and the second bent portion 204 is fixedly connected to the second portion 203 and the third portion 205.

[0084] The first part 201 is fixedly connected to the first housing 1, the second part 203 is fixedly connected to the second housing 2, and the third part 205 is fixedly connected to the third housing 3. The first bending part 202 is positioned corresponding to the first rotating shaft 4, and deforms during the relative folding or unfolding of the first housing 1 and the second housing 2. The second bending part 204 is positioned corresponding to the second rotating shaft 5, and deforms during the relative folding or unfolding of the second housing 2 and the third housing 3. During the relative folding or unfolding of the first housing 1, the second housing 2, and the third housing 3, the first housing 1 drives the first part 201 to move, the second housing 2 drives the second part 203 to move, and the third housing 3 drives the third part 205 to move. The first part 201 and the second part 203 fold or unfold relative to each other, and the second part 203 and the third part 205 fold or unfold relative to each other, thereby causing the electronic device 100 to fold or unfold.

[0085] In this embodiment, since the first part 201 is fixedly connected to the first housing 1, the second part 203 is fixedly connected to the second housing 2, and the third part 205 is fixedly connected to the third housing 3, when the first housing 1, the second housing 2, and the third housing 3 are folded or unfolded relative to each other, the relative folding and unfolding actions between the first part 201, the second part 203, and the third part 205 can be accurately controlled, making the deformation process and movement shape of the flexible display screen 20 controllable and highly reliable.

[0086] As shown in Figure 1, when the first housing 1, the second housing 2, and the third housing 3 are unfolded to the open state, the first part 201, the first bending part 202, the second part 203, the second bending part 204, and the third part 205 of the flexible display screen 20 are relatively flattened and form a flat plate structure, and the flexible display screen 20 is in a flattened state.

[0087] As shown in Figure 2, when the first housing 1, the second housing 2, and the third housing 3 are in an intermediate state, the first housing 1 and the second housing 2 are open relative to each other, and the second housing 2 and the third housing 3 are folded relative to each other. It should be understood that in other cases, such as the first housing 1 and the second housing 2 being folded relative to each other and the second housing 2 and the third housing 3 being open relative to each other, this can also be an intermediate state of the electronic device 100. Additionally, an angle is formed between the first portion 201 and the second portion 203 of the flexible display screen 20, causing the first bending portion 202 to bend; or an angle is formed between the second portion 203 and the third portion 205 of the flexible display screen 20, causing the second bending portion 204 to bend; this can also be an intermediate state of the electronic device 100. This embodiment will not provide examples of all intermediate states of the electronic device 100.

[0088] As shown in Figures 3 and 4, when the first housing 1, the second housing 2, and the third housing 3 are folded to a closed state, the flexible display screen 20 is located inside the housing assembly and is in a folded state. The first portion 201 faces the second housing 2, while the second portion 203 and the third portion 205 face each other. For example, the first bending portion 202 undergoes bending deformation, and can be approximately U-shaped, creating a gap between the first portion 201 and the second portion 203, thus facilitating the accommodation of the third housing 3. The second bending portion 204 undergoes bending deformation, and can be approximately teardrop-shaped, creating a smaller gap between the second portion 203 and the third portion 205, thus facilitating the close proximity of the second housing 2 and the third housing 3, thereby reducing the thickness of the electronic device 100 in the closed state.

[0089] It is understood that during the process of the electronic device 100 transforming from the open state shown in Figure 1 to the closed state shown in Figure 3, the second housing 2 and the third housing 3 can be folded first, that is, the second housing 2 and the third housing 3 first form the intermediate state shown in Figure 2, and then the first housing 1 and the second housing 2 are folded to form the closed state shown in Figure 3. During this folding process, the first housing 1 and the third housing 3 are less likely to collide, which helps to protect the housing device 10 of the electronic device 100 and the flexible display screen 20. It is understood that the process of the electronic device 100 transforming from the closed state to the open state is the reverse of the above process.

[0090] The flexible display screen 20 may include a display module and a support plate (not shown). The display module is the flexible display screen 20, and the support plate is located below the display module to support the display module and increase its structural rigidity. The rigidity of the support plate at the first bending portion 202 and the second bending portion 204 is less than the rigidity of the support plate at the first portion 201, the second portion 203, and the third portion 205. That is, the rigidity of the support plate at the first bending portion 202 and the second bending portion 204 is smaller, while the rigidity of the support plate at the first portion 201, the second portion 203, and the third portion 205 is larger. This allows the flexible display screen 20 to balance structural rigidity and high flatness, while also allowing the bending portions of the flexible display screen 20 to bend smoothly.

[0091] The display module can integrate display and touch sensing functions. The flexible display screen 20 displays images and videos, while its touch sensing function detects user touch actions to enable human-computer interaction. The display module can utilize various display technologies, including liquid crystal displays (LCDs), organic light-emitting diode (OLED) displays, active-matrix organic light-emitting diode (AMOLED) displays, flexible light-emitting diode (FLED) displays, MiniLED displays, MicroLED displays, Micro-OLED displays, and quantum dot light-emitting diode (QLED) displays.

[0092] In some embodiments, please refer to Figures 4 and 5, the housing device 10 may have a mounting groove 101, and the flexible display screen 20 may be mounted in the mounting groove 101.

[0093] The mounting groove 101 can be formed by the first housing 1, the second housing 2 and the third housing 3; the mounting groove 101 can be recessed relative to the surface of the housing device 10.

[0094] For example, the mounting groove 101 is a first slot 11 in the first housing 1, a second slot 21 in the second housing 2, and a third slot 31 in the third housing 3. The bottom surface of the first slot 11 is a first support surface 111, the bottom surface of the second slot 21 is a second support surface 211, and the bottom surface of the third slot 31 is a third support surface 311. The first portion 201 of the flexible display screen 20 is mounted in the first slot 11, and the first support surface 111 supports the first portion 201. The second portion 203 of the flexible display screen 20 is mounted in the second slot 21, and the second support surface 211 supports the second portion 203. The third portion 205 of the flexible display screen 20 is mounted in the third slot 31, and the third support surface 311 supports the third portion 205.

[0095] When the flexible display screen 20 is installed in the mounting groove 101, the surface height of the flexible display screen 20 is lower than the side wall height of the mounting groove 101. The side wall of the mounting groove 101 can wrap around the edge of the flexible display screen 20, thereby reducing the impact of other objects on the edge of the flexible display screen 20 and helping to protect the flexible display screen 20.

[0096] The first portion 201 of the flexible display screen 20 can be fixedly connected to the first housing 1. For example, the first portion 201 can be fixed to the first support surface 111 by adhesive bonding. For example, the first portion 201 can be bonded to the support surface of the first housing 1 by an adhesive layer. The second portion 203 is fixedly connected to the second housing 2. For example, the second portion 203 can be fixed to the second support surface 211 by adhesive bonding. The third portion 205 of the flexible display screen 20 can be fixedly connected to the support surface of the third housing 3. For example, the third portion 205 can be fixed to the third support surface 311 by adhesive bonding.

[0097] It is understood that the first support surface 111 of the first housing 1, the second support surface 211 of the second housing 2, and the third support surface 311 of the third housing 3 can be continuous and complete surfaces, or they can be surfaces including multiple recessed areas or hollow areas. This application embodiment does not strictly limit this.

[0098] In some embodiments, referring to Figures 1 and 3, the electronic device 100 may further include a rear camera 6. The rear camera 6 may be mounted on the side of the second housing 2 opposite to the second portion 203. The rear camera 6 can be used for taking pictures. When the electronic device is in a folded state, the rear camera 6 may be located on the top side of the electronic device in a second direction. This embodiment does not specifically limit the structure or shape of the rear camera 6.

[0099] Please refer to Figure 6, which is an exploded structural diagram of the housing device 10 shown in Figure 5.

[0100] In some embodiments, the first housing 1 may include a first middle plate 12 and a first frame 13. The first frame 13 may be fixedly connected to the first middle plate 12. The first housing 1 may have a width direction, a length direction, and a thickness direction. The width direction may be parallel to the X direction, the length direction may be parallel to the Y direction, and the thickness direction may be parallel to the Z direction.

[0101] For example, the first intermediate plate 12 may be generally rectangular in shape. The first intermediate plate 12 may be a thin shell, and its interior may have mounting space (not shown) for mounting components of the electronic device 100. A first mating groove 121 may be provided on one side of the first intermediate plate 12.

[0102] For example, the first frame 13 may include a first edge strip 131, a second edge strip 132, and a third edge strip 133. The first edge strip 131, the second edge strip 132, and the third edge strip 133 are connected sequentially. The first frame 13 may be installed at the edge of the first middle plate 12. For example, the first edge strip 131, the second edge strip 132, and the third edge strip 133 are respectively located on the three sides of the first middle plate 12, with the first edge strip 131 and the third edge strip 133 being opposite and parallel to each other, and the second edge strip 132 being located on the side of the first middle plate 12 away from the first mating groove 121. In this case, the first frame 13 has a roughly "C" shaped structure, and the first frame 13 protrudes at least partially from the first middle plate 12 in the Z direction, forming the first groove 11.

[0103] It should be understood that the first housing 1 can be made of materials such as metal and plastic, but is not limited to them. The first housing 1 can be formed by splicing or assembling different parts, such as by bonding, threaded connection, welding, embedding, etc. This embodiment does not strictly limit this.

[0104] In some embodiments, the first housing 1 may further include a protrusion 14. The protrusion 14 may be fixed to the first middle plate 12 and protrude relative to the first middle plate 12. Since the protrusion 14 protrudes from the first middle plate 12, the height of the first housing 1 is relatively high, which is beneficial for installing larger components inside the protrusion 14.

[0105] In the electronic device 100, the protrusion 14 and the first portion 201 can be located on the same side of the first middle plate 12. In the electronic device 100, the protrusion 14 is located on the side of the first frame 13 opposite to the first portion 201 (see FIG. 1). The protrusion 14 can be disposed adjacent to the second side strip 132 of the first frame 13, and the protrusion 14 can be located on the outer side of the first frame 13. The length of the protrusion 14 can be approximately the same as the length of the first middle plate 12.

[0106] For example, the top surface 140 of the protrusion 14 may be a plane. In the thickness direction (Z direction) of the first housing 1, the highest point of the protrusion 14 is located on the top surface 140 of the protrusion 14.

[0107] In some other examples, the first housing 1 may not have the protrusion 14. In this case, the thickness of the first housing 1 can be substantially uniform throughout, and the thickness of the first housing 1 can depend on the first middle plate 12 and the first frame 13.

[0108] In some embodiments, the first rotating shaft 4 may include a first connecting portion 41, a first main shaft 42, and a second connecting portion 43. The first connecting portion 41 and the second connecting portion 43 are rotatably connected to the first main shaft 42. The first connecting portion 41 and the second connecting portion 43 are each rotatable relative to the first main shaft 42, and they can also rotate synchronously relative to the first main shaft 42. This embodiment does not strictly limit the structure and motion principle of the first rotating shaft 4.

[0109] In some embodiments, the second housing 2 may include a second middle plate 22 and a second side frame 23. The second side frame 23 may be fixedly connected to the second middle plate 22. The second housing 2 may have a width direction, a length direction, and a thickness direction. The width direction may be parallel to the X direction, the length direction may be parallel to the Y direction, and the thickness direction may be parallel to the Z direction.

[0110] For example, the second intermediate plate 22 may be generally rectangular in shape. The second intermediate plate 22 may be a thin shell, and its interior may have mounting space (not shown) for mounting components of the electronic device 100. The second intermediate plate 22 may be provided with a second mating groove 221 and a third mating groove 222, which are located on two opposite sides of the second intermediate plate 22.

[0111] For example, the second frame 23 may include a first edge strip 231 and a second edge strip 232. The second frame 23 may be installed at the edge of the second middle plate 22, such that the first edge strip 231 and the second edge strip 232 are located on two sides of the second middle plate 22, and the first edge strip 231 and the second edge strip 232 are arranged opposite to each other and parallel to each other. In this case, the second frame 23 protrudes at least partially from the second middle plate 22 in the thickness direction (Z direction). The second frame 23 may form a second groove 21.

[0112] It should be understood that the second housing 2 can be made of materials such as metal and plastic, but is not limited to them. The second housing 2 can be formed by splicing or assembling different parts, such as by bonding, threaded connection, welding, embedding, etc. This embodiment does not strictly limit this.

[0113] In some embodiments, the second rotating shaft 5 may include a third connecting portion 51, a second main shaft 52, and a fourth connecting portion 53. The third connecting portion 51 and the fourth connecting portion 53 are rotatably connected to the second main shaft 52. The third connecting portion 51 and the fourth connecting portion 53 can rotate relative to the second main shaft 52, and they can also rotate synchronously relative to the second main shaft 52. This embodiment does not strictly limit the structure and motion principle of the second rotating shaft 5.

[0114] In some embodiments, the third housing 3 may include a third middle plate 32 and a third frame 33. The third frame 33 is fixedly connected to the third middle plate 32. The third housing 3 may have a width direction, a length direction, and a thickness direction. The width direction may be parallel to the X direction, the length direction may be parallel to the Y direction, and the thickness direction may be parallel to the Z direction.

[0115] For example, the third intermediate plate 32 may be generally rectangular in shape. The third intermediate plate 32 may be a thin shell, and its interior may have mounting space (not shown) for mounting components of the electronic device 100. A fourth mating groove 321 may be provided on one side of the third intermediate plate 32.

[0116] For example, the third frame 33 may include a first edge strip 331, a second edge strip 332, and a third edge strip 333. The first edge strip 331, the second edge strip 332, and the third edge strip 333 are connected sequentially. The first frame 13 may be installed at the edge of the third middle plate 32. For example, the first edge strip 331, the second edge strip 332, and the third edge strip 333 are respectively located on the three sides of the third middle plate 32, and the first edge strip 331 and the third edge strip 333 are arranged opposite to each other and parallel to each other, while the second edge strip 332 is located on the side of the third middle plate 32 away from the fourth mating groove 321. At this time, the third frame 33 has a roughly "C" shaped structure, and the third frame 33 protrudes from the third middle plate 32 at least partially in the thickness direction (Z direction), and the third frame 33 can form the third groove 31.

[0117] It should be understood that the third housing 3 can be made of materials such as metal and plastic, but is not limited to them. The third housing 3 can be formed by splicing or assembling different parts, such as by bonding, threaded connection, welding, embedding, etc. This embodiment does not strictly limit this.

[0118] In some embodiments, the first housing 1, the first rotating shaft 4, the second housing 2, the second rotating shaft 5, and the third housing 3 can be connected in sequence.

[0119] For example, the first connecting part 41 of the first rotating shaft 4 can be fixedly connected to the first docking groove 121 of the first housing 1, the second connecting part 43 of the first rotating shaft 4 can be fixedly connected to the second docking groove 221 of the second housing 2, the third connecting part 51 of the second rotating shaft 5 can be fixedly connected to the third docking groove 222 of the second housing 2, and the fourth connecting part 53 of the second rotating shaft 5 can be fixedly connected to the fourth docking groove 321 of the third housing 3. Through the movement of the first rotating shaft 4 and the second rotating shaft 5, the first housing 1, the second housing 2 and the third housing 3 can be folded and unfolded relative to each other, and the relative movement between the first housing 1 and the second housing 2 and the relative movement between the second housing 2 and the third housing 3 can be independent of each other.

[0120] For example, when the housing device 10 is opened, in the first direction (X direction), the length of the second side strip 332 of the third frame 33 is the same as the spacing between the first side strip 331 and the third side strip 333 of the third frame 33. The spacing between the first side strip 331 and the third side strip 333 of the third frame 33 can be the spacing between the portions of the two strips protruding from the third middle plate 32.

[0121] At this time, the first edge strip 131 of the first frame 13, the first edge strip 231 of the second frame 23, and the first edge strip 331 of the third frame 33 can be located on the same side of the housing device 10. For example, when the housing device 10 is in the unfolded state, the three can be collinear. Similarly, the third edge strip 133 of the first frame 13, the second edge strip 232 of the second frame 23, and the third edge strip 333 of the third frame 33 can be located on the same side of the housing device 10. For example, when the housing device 10 is in the unfolded state, the three can be collinear. The first slot 11, the second slot 21, and the third slot 31 can be interconnected to form the mounting slot 101.

[0122] In the electronic device 100, referring to FIG1, the first part 201 of the flexible display screen 20 can be located inside the first frame 13, the second part 203 can be located inside the second frame 23, and the third part 205 can be located inside the third frame 33.

[0123] In this configuration, in the direction perpendicular to the flexible display screen 20 (i.e., the Z-direction), the surface of the first frame 13 can be higher than the surface of the first portion 201, and the surface of the third frame 33 is higher than or equal to the surface of the third portion 205. In this case, a portion of the side surface of the first portion 201 is surrounded by the first frame 13, and a portion of the side surface of the third portion 205 is surrounded by the third frame 33, thus facilitating the protection of the flexible display screen 20 by the first frame 13 and the third frame 33. Similarly, the surface of the second frame 23 can be higher than the surface of the second portion 203. In this case, a portion of the side surface of the second portion 203 is surrounded by the second frame 23, thus facilitating the protection of the flexible display screen 20 by the second frame 23.

[0124] In some other embodiments, the height of the flexible display screen 20 may be flush with the height of the first frame 13, the second frame 23, and the third frame 33, or the height of the flexible display screen 20 may be higher than the height of the first frame 13, the second frame 23, and the third frame 33.

[0125] Please refer to Figures 4 and 5. In some embodiments, when the electronic device 100 is in a closed state, the top surface 140 of the protrusion 14 may be higher than the third housing 3 in the arrangement direction of the first housing 1, the second housing 2, and the third housing 3. In this case, the protrusion 14 can protect the side of the third housing 3 and part of the side of the second housing 2, preventing the side of the third housing 3 from being collided with by other objects, and also reducing the probability of the second housing 2 being accidentally opened. Furthermore, the protrusion 14, the first housing 1, and the second housing 2 can surround the third housing 3, thereby jointly protecting the third housing 3 and improving the reliability of the electronic device 100.

[0126] In some embodiments, when the electronic device 100 is in a closed state, the top surface 140 of the protrusion 14 may be higher than or equal to the second housing 2 to protect the second housing 2. In other embodiments, the top surface 140 of the protrusion 14 may be lower than the second housing 2.

[0127] Please refer to Figure 7, which is a schematic diagram of the structure of the electronic device 100 shown in Figure 1 in some embodiments.

[0128] In some embodiments, the corners of the third housing 3 may be chamfered.

[0129] For example, the connection between the first side strip 331 and the second side strip 332 of the third border 33 can form an arc-shaped structure.

[0130] For example, the third frame 33 may have a first side 334, a second side 335, and a third side 336. The second side 335, the first side 334, and the third side 336 may be connected sequentially. The second side 335 and the third side 336 may be arranged opposite to each other. Specifically, the first side 334 is located on the side of the second side strip 332 of the third frame 33 that is away from the second pivot 5; the second side 335 is located on the side of the first side strip 331 of the third frame 33 that is away from the third side strip 333 of the third frame 33; and the third side 336 is located on the side of the third side strip 333 of the third frame 33 that is away from the first side strip 331 of the third frame 33. Specifically, the first side 334 may extend along the length direction of the third housing 3, and the second side 335 and the third side 336 may extend along the width direction of the third housing 3; the height direction of the first side 334, the height direction of the second side 335, and the height direction of the third side 336 are the same as the height direction of the third housing 3.

[0131] The first edge strip 331 of the third frame 33 has a first end 3311, which is the end of the first edge strip 331 away from the second pivot 5. The first end 3311 has a first end face 3312, which is connected to the first side face 334.

[0132] The third edge strip 333 of the third frame 33 has a second end 3331, which is the end of the third edge strip 333 away from the second pivot 5. The second end 3331 has a second end face 3332, which is connected to the first side face 334.

[0133] At this point, the sides of the third shell 3 can transition smoothly. When the third shell 3 collides with other objects, the force-bearing area of ​​the third shell 3 is larger, the contact stress is smaller, and the damage to the third shell 3 and other objects is less.

[0134] In some embodiments, the corners of the third housing 3 have larger rounded corners, resulting in a greater degree of transition.

[0135] For example, the first end face 3312 may form part of the arc surface between the second side strip 332 and the first side strip 331 of the third frame 33. When the electronic device 100 is in the open state, in a first direction, the height of the first end face 3312 is lower than the height of the first side surface 334. At this time, it is equivalent to a large amount of material removal from the corners of the third housing 3, with the rounded corners intruding into the second side strip 332 of the third frame 33, and a portion of the structure at the end of the first side strip 331 of the third frame 33 being removed.

[0136] Similarly, the second end face 3332 can also form part of the arc surface between the second edge strip 332 and the third edge strip 333 of the third frame 33. The structure of the second end face 3332 will not be described in detail in this embodiment. In some examples, the structure of the second end face 3332 can be symmetrical to the structure of the first end face 3312.

[0137] Please refer to Figure 8, which is a structural schematic diagram of the electronic device 100 shown in Figure 7 in some embodiments of its usage.

[0138] In some embodiments, as shown in FIG8, when a user opens and closes the electronic device 100, or folds the electronic device 100, if the operation is too fast or the electronic device 100 falls, the third housing 3 may collide with the first housing 1 or the first part 201 of the flexible display screen 20.

[0139] At this time, the first housing 1 and the second housing 2 of the electronic device 100 are folded relative to each other to a first angle α, and the second housing 2 and the third housing 3 of the electronic device 100 are folded relative to each other to a second angle β. The first angle α is greater than the second angle β, that is, the degree of folding of the second housing 2 and the third housing 3 is greater than the degree of folding of the first housing 1 and the second housing 2. Referring to Figure 7, the first side 334 of the third housing 3 faces the first part 201 and corresponds to the first part 201.

[0140] When the flexible display screen 20 is flush with the first frame 13 of the first housing 1, and when the corner radius of the third housing 3 is large, neither the first end 3311 nor the second end 3331 can contact the first frame 13 of the first housing 1 in time, and the third frame 33 cannot be supported by the first frame 13 in time. Therefore, the second edge strip 332 of the third frame 33 will contact the first part 201 first, thereby impacting the first part 201 and easily causing the first part 201 to be damaged and fail. As shown in Figure 8, after the second edge strip 332 of the third frame 33 interferes with the first part 201 (the dotted area in Figure 8 is the interference area), the first edge strip 331 of the third frame 33 has not yet contacted the first frame 13, and the first edge strip 131 of the first frame 13 cannot support the first edge strip 331 of the third frame 33.

[0141] To address the technical problems arising from the above embodiments, the technical solution will be further optimized below.

[0142] This application provides an electronic device, which includes a housing and a flexible display screen, with the flexible display screen fixed to the housing. The housing includes a first housing, a second housing, a third housing, a first pivot, and a second pivot. The first pivot connects the first housing and the second housing, and the second pivot connects the second housing and the third housing. The first housing and the second housing can be folded and opened relative to each other via the first pivot, and the second housing and the third housing can be folded and opened relative to each other via the second pivot.

[0143] The first housing includes a first middle plate and a first frame, with the first frame fixedly connected to the first middle plate. The second housing includes a second middle plate and a second frame, with the second frame fixedly connected to the second middle plate. The third housing includes a third middle plate and a third frame, with the third frame fixedly connected to the third middle plate.

[0144] The flexible display screen includes a first part, a first bent part, a second part, a second bent part, and a third part connected in sequence; the first part is installed on a first middle plate and located inside the first frame; the second part is installed on a second middle plate and located inside the second frame; the third part is installed on a third middle plate and located inside the third frame.

[0145] When the electronic device is in the open state, the first housing, the second housing, and the third housing are arranged along the first direction. The first part, the first bend, the second part, the second bend, and the third part are flat plate structures. When the electronic device is in the closed state, the third housing is located between the first housing and the second housing. The first bend and the second bend are respectively bent structures. The second part and the third part are arranged facing each other.

[0146] When the first housing is folded relative to the second housing to a first angle a and the third housing is folded relative to the second housing to a second angle b, the third frame abuts against the first frame and is disposed opposite and spaced apart from the first portion, wherein the first angle a is greater than the second angle b.

[0147] Wherein, the first angle a satisfies 0° < a < 180°, the second angle b satisfies 0° < c < 180°. In addition, there may be a third angle c between the first housing and the third housing, and the third angle c satisfies 0° < c < 180°, and a + b + c = 180°. It can be understood that the first angle a and the second angle b indicate that the first housing, the second housing, and the third housing of the electronic device can be folded to a certain extent so that the first housing and the third housing can contact, rather than a limitation on the form or structure of the electronic device.

[0148] Wherein, the third frame being opposite to the first portion may mean that in the direction perpendicular to the first portion, the projection of the portion of the first portion exposed from the first frame coincides with the projection of the third frame.

[0149] In this embodiment, since the third frame can abut against the first frame and is spaced apart from the first portion in the direction perpendicular to the first portion, at this time, the first frame generates a supporting force on the third frame, and the third frame cannot contact the first portion. Therefore, during the use of the electronic device by the user, such as when folding the electronic device or when the electronic device is impacted, the third frame will not impact the first portion of the flexible display screen, which is beneficial to improving the service life of the flexible display screen and further improving the service life of the electronic device.

[0150] The following is illustrated by specific but non-limiting examples.

[0151] Please refer to FIG. 9, which is a schematic structural diagram of the electronic device 100 shown in FIG. 1 in some other embodiments.

[0152] In some embodiments, when the electronic device 100 is in the open state, in the first direction (X direction), the height of the highest point of the first side strip 331 of the third frame 33 may be equal to the height of the highest point of the second side strip 332 of the third frame 33.

[0153] For example, the second side strip 332 of the third frame 33 may have a first side surface 334, and the first side surface 334 is located on the side of the second side strip 332 of the third frame 33 facing away from the second pivot 5. The first side surface 334 may be the outermost surface of the second side strip 332 of the third frame 33 in the X direction. For example, the length of the first side surface 334 may be the same as the length of the second side strip 332 of the third frame 33. For example, the first side surface 334 may be a plane, in which case the first side surface 334 is easy to shape. In some other examples, the first side surface 334 may be a curved surface; for example, the first side surface 334 may be formed by an arc extending along the Y direction.

[0154] For example, the first strip 331 of the third frame 33 may have a first end 3311. The first end 3311 is the end of the first strip 331 of the third frame 33 that is away from the second pivot 5. The first end 3311 has a first end face 3312, which faces away from the second pivot 5. In the length direction of the first strip 331 of the third frame 33, i.e., the first direction (X direction), the highest point of the first strip 331 of the third frame 33 is located at the first end face 3312, and the height of the first end face 3312 is equal to the height of the first side face 334. In some other examples, in the length direction of the first strip 331 of the third frame 33, the height of the first end face 3312 may be higher than the height of the first side face 334, which is equivalent to the first end face 3312 protruding relative to the first side face 334. In this case, the first end 3311 protrudes from the second strip 332 of the third frame 33, and the first end face 3312 and the first side face 334 can be connected by other surfaces.

[0155] For example, the first end face 3312 can be a plane. For example, the first end face 3312 is perpendicular to the X direction. In some other examples, the first end face 3312 can also be a curved surface.

[0156] For example, the first side surface 334 and the first end surface 3312 can be flush. The first end surface 3312 and the first side surface 334 are located on the same side of the third frame 33, and the first end surface 3312 is connected to the first side surface 334. In this case, the first side surface 334 and the first end surface 3312 are flush, making the surface of the third frame 33 smoother and the shape simpler. Furthermore, the first side surface 334 and the first end surface 3312 can be formed simultaneously, facilitating the manufacturing of the third frame 33.

[0157] In some embodiments, when the electronic device 100 is in the open state, in the first direction (X direction), the height of the highest point of the third side strip 333 of the third frame 33 is equal to the height of the highest point of the second side strip 332 of the third frame 33.

[0158] For example, the third edge strip 333 of the third frame 33 has a second end 3331, which is the end of the third edge strip 333 of the third frame 33 away from the second pivot 5. The second end 3331 has a second end face 3332, and the first end face 3312 faces away from the second pivot 5. The second end face 3332 is connected to the first side face 334. For example, the second end face 3332 can be a plane. For example, the second end face 3332 is perpendicular to the X direction. In the length direction of the third edge strip 333 of the third frame 33, the highest point of the third edge strip 333 of the third frame 33 is located at the second end face 3332, and the height of the second end face 3332 is equal to the height of the first side face 334. In some other examples, the height of the second end face 3332 can be higher than the height of the first side face 334 in the length direction of the third edge strip 333 of the third frame 33. In some other examples, the second end face 3332 can also be a curved surface.

[0159] For example, the first side surface 334 and the second end surface 3332 can be set flush.

[0160] In some embodiments, the first end face 3312 and the second end face 3332 can be symmetrically arranged to make the shape of the third border 33 more regular.

[0161] In some embodiments, the first edge strip 331 of the third frame 33 has a second side surface 335 and a first transition surface 3313. The second side surface 335 is located on the side of the first edge strip 331 of the third frame 33 that is opposite to the third edge strip 333 of the third frame 33, and the first transition surface 3313 connects the second side surface 335 and the first end face 3312. In this embodiment, the first end face 3312 and the second side surface 335 are connected by the first transition surface 3313, making the transition between the first end face 3312 and the second side surface 335 smoother, avoiding sharp corners of the first edge strip 331 of the third frame 33, which helps to reduce the stress when the first end face 3312 comes into contact with other objects, thereby protecting the third frame 33, improving the service life of the housing device 10 and the electronic device 100, and also improving the user's feel.

[0162] For example, the second side surface 335 can be a plane to facilitate shaping. The second side surface 335 can be perpendicular to the Y direction. The length of the second side surface 335 can be approximately equal to the width of the third portion 205. This embodiment does not strictly limit the shape and size of the second side surface 335. In some other examples, the second side surface 335 can also be a curved surface.

[0163] For example, the dimension of the first transition surface 3313 in the length direction (X direction) of the first edge strip 331 of the third frame 33 can be larger than the dimension of the second edge strip 332 of the third frame 33 in the length direction (X direction) of the first edge strip 331 of the third frame 33. The dimension of the first transition surface 3313 in the length direction (Y direction) of the second edge strip 332 of the third frame 33 can be smaller than the dimension of the first edge strip 331 of the third frame 33 in the length direction (Y direction) of the second edge strip 332 of the third frame 33. In this case, it is advantageous to have a larger dimension for the first transition surface 3313, thereby facilitating a smooth transition between the first end face 3312 and the second side face 335. In some examples, the first transition surface 3313 can be a plane, making the structure of the first edge strip 331 of the third frame 33 simpler and thus easier to form. In other embodiments, the first transition surface 3313 can be a curved surface, making the surface of the first edge strip 331 of the third frame 33 smoother.

[0164] In some embodiments, the third edge strip 333 of the third frame 33 has a third side surface 336 and a second transition surface 3333. The third side surface 336 is located on the side of the third edge strip 333 of the third frame 33 that is opposite to the first edge strip 331 of the third frame 33. The second transition surface 3333 connects the third side surface 336 and the second end face 3332. The specific structure of the third side surface 336 and the second transition surface 3333 can refer to the relevant schemes of the second side surface 335 and the first transition surface 3313, which will not be described in detail in this embodiment. For example, the third side surface 336 and the second side surface 335 can be symmetrically arranged, and the second transition surface 3333 and the first transition surface 3313 can be symmetrically arranged.

[0165] In some embodiments, the first edge strip 131 of the first frame 13 may have a first top surface 134. The first top surface 134 is perpendicular to the thickness direction of the first portion 201 and is located on the same side of the first middle plate 12 (see FIG. 6) as the first portion 201. The first top surface 134 may be planar to facilitate molding.

[0166] It should be understood that the other sides of the first top surface 134 and the first frame 13 can be smoothly transitioned by small curved surfaces or small planes to avoid the junction between different surfaces being too sharp.

[0167] Additionally, the third edge strip 133 of the first frame 13 may also have a second top surface. The second top surface is perpendicular to the thickness direction of the first portion 201 and is located on the same side of the first middle plate 12 as the first portion 201. The second top surface may be planar to facilitate molding.

[0168] Please refer to Figures 9 and 10. Figure 10 is a structural schematic diagram of the electronic device 100 shown in Figure 9 in some embodiments of its usage.

[0169] In some embodiments, when the first housing 1 and the second housing 2 of the electronic device 100 are folded to a first angle a and the second housing 2 and the third housing 3 are folded to a second angle b, the third housing 3 can abut against the first housing 1.

[0170] As mentioned above, referring to Figure 3, the third shell 3 can be located between the first shell 1 and the second shell 2; and the first shell 1 and the third shell 3 can rotate relative to the second shell 2. Therefore, when the first shell 1 and the second shell 2 are folded to the first angle α, and the second shell 2 and the third shell 3 are folded to the second angle β; that is, when both the first shell 1 and the third shell 3 are folded relative to the second shell 2, and the degree of folding of the second shell 2 and the third shell 3 is greater, there are some angle combinations of the first angle α and the second angle β that bring the third shell 3 and the first shell 1 closer together and into contact, thereby causing the first shell 1, the second shell 2 and the third shell 3 to contact each other and form a triangular structure.

[0171] At this time, the first end face 3312 is directly opposite the first side strip 131 of the first frame 13, while the first side face 334 faces the first part 201.

[0172] Specifically, when the first angle 'a' is greater than the second angle 'b', the bending degree of the second shell 2 and the third shell 3 is greater than that of the first shell 1 and the second shell 2, making it easier for the third shell 3 to come into contact with the first shell 1. In addition, when the length of the third shell 3 is less than that of the first shell 1, there are some combinations of the first angle 'a' and the second angle 'b', where the first angle 'a' is less than the second angle 'b', and the bending degree of the second shell 2 and the third shell 3 is greater than that of the first shell 1 and the second shell 2, thus enabling the third shell 3 to come into contact with the first shell 1.

[0173] In this embodiment, since the third frame 33 can abut against the first frame 13, and there is a gap between the third frame 33 and the first portion 201 in the direction perpendicular to the first portion 201, the first frame 13 generates a supporting force on the third frame 33. The second edge strip 332 of the third frame 33 cannot contact the first portion 201, meaning the third frame 33 cannot contact the first portion 201. Therefore, during the use of the electronic device 100, such as when folding the electronic device 100 or when the electronic device 100 is impacted, the third frame 33 will not impact the first portion 201 of the flexible display screen 20, thereby improving the service life of the flexible display screen 20 and consequently, the service life of the electronic device 100.

[0174] In some embodiments, as described above, the highest point of the second side strip 332 of the third frame 33 is located on the first side surface 334 along the length of the first side strip 331 of the third frame 33; the highest point of the first side strip 331 of the third frame 33 is located on the first end face 3312 along the length of the first side strip 331 of the third frame 33, and the first end face 3312 is higher than or equal to the height of the first side surface 334. At this time, the distance between the first end face 3312 and the first side strip 131 of the first frame 13 is always less than the distance between the first side surface 334 and the first portion 201. Therefore, when the electronic device 100 is folded from the open state to the first housing 1 folded relative to the second housing 2 at a first angle a, and the third housing 3 folded relative to the second housing 2 at a second angle b, the first end face 3312 will first abut against the first side strip 131 of the first frame 13, while simultaneously ensuring that the first side surface 334 and the first portion 201 are spaced apart in a direction perpendicular to the first portion 201, thus preventing the first portion 201 from being collided with. In addition, this embodiment has fewer restrictions on the first side surface 334 and the first end surface 3312, which is conducive to designing the surface shape of the first side surface 334 and the first end surface 3312 according to requirements.

[0175] Furthermore, since the first edge strip 331 of the third frame 33 has a first transition surface 3313, by setting the first transition surface 3313, the connection between the first edge strip 331 and the second edge strip 332 of the third frame 33 can be made smoother, which is beneficial to improving the user experience of the electronic device 100 and can also prevent the third frame 33 from colliding with the first part 201.

[0176] Similarly, along the length of the third edge strip 333 of the third frame 33, the highest point of the third edge strip 333 of the third frame 33 is located at the second end face 3332, and the second end face 3332 is higher than or equal to the height of the first side face 334. At this time, when the electronic device 100 is folded from the open state to the first housing 1 folded relative to the second housing 2 at a first angle a, and the third housing 3 folded relative to the second housing 2 at a second angle b (as shown in Figure 10), the second end face 3332 will first abut against the third edge strip 133 of the first frame 13, while simultaneously ensuring that the first side face 334 and the first part 201 are spaced apart in a direction perpendicular to the first part 201, thus preventing the first part 201 from being collided with. Furthermore, since both the first end face 3312 and the second end face 3332 abut against the first frame 13, it helps to balance the force on the third frame 33, preventing the third frame 33 from twisting, reducing the probability of the third frame 33 colliding with the first part 201, and improving the reliability of the electronic device 100.

[0177] Furthermore, since the third edge strip 333 of the third frame 33 has a second transition surface 3333, by setting the second transition surface 3333, the connection between the third edge strip 333 and the second edge strip 332 of the third frame 33 can be made smoother, which is beneficial to improving the user experience of the electronic device 100 and can also prevent the third frame 33 from colliding with the first part 201.

[0178] In some embodiments, as described above, in the direction perpendicular to the first portion 201, the surface of the first portion 201 is lower than the height of the first frame 13, or the surface of the first portion 201 is flush with the first frame 13. In this case, in the direction perpendicular to the first portion 201, the first portion 201 is flush with or recessed relative to the first frame 13. When the first frame 13 contacts the third frame 33, it helps to increase the distance between the first side 334 and the first portion 201, thereby further preventing the third frame 33 from colliding with the first portion 201 and improving the reliability of the electronic device 100.

[0179] Furthermore, as mentioned above, the first side surface 334 and the first end surface 3312 can be coplanar. The first end surface 3312 and the first side surface 334 form a plane. The first side surface 334 and the second end surface 3332 can be flush. The second end surface 3332 and the first side surface 334 form a plane. At this time, the first end surface 3312 can contact the first edge strip 131 of the first frame 13, and the second end surface 3332 can contact the third edge strip 133 of the first frame 13. When the third frame 33 is slightly twisted relative to the first frame 13, the first end face 3312 may be slightly misaligned with the first edge strip 131 of the first frame 13, and the second end face 3332 may be slightly misaligned with the third edge strip 133 of the first frame 13 (see Figure 6). However, the second edge strip 332 of the third frame 33 can continue to abut against the first frame 13. Therefore, the second edge strip 332 of the third frame 33 and the surface of the first part 201 are always spaced apart, thereby avoiding collision between the third frame 33 and the first part 201 of the flexible display screen 20, thereby improving the lifespan of the flexible display screen 20.

[0180] In some embodiments, as described above, the first top surface 134 of the first edge strip 131 of the first frame 13 can be a plane. The shape of the first top surface 134 is more adapted to the shape of the first end face 3312. When the first end face 3312 abuts against the surface of the first edge strip 131 of the first frame 13, that is, when the first end face 3312 abuts against the first top surface 134, the first top surface 134 can have a larger contact area with the first end face 3312. On the one hand, this can improve the reliability of the abutment between the first end face 3312 and the first top surface 134. On the other hand, it can also reduce the abutment stress of the first edge strip 131 of the first frame 13 and the first edge strip 331 of the third frame 33, and reduce the collision damage of both.

[0181] In some other examples, in the thickness direction of the first part 201, when the surface of the first part 201 is flush with the surface of the first frame 13, when the first end 3311 and the first edge strip 131 of the first frame 13 are in contact, the second edge strip 332 of the third frame 33 is in contact with the surface of the first part 201, but can be regarded as not being under force, and can also avoid the third frame 33 from hitting the first part 201, thereby improving the life of the electronic device 100.

[0182] In some other examples, the first end face 3312 is higher than the height of the first side face 334 in the length direction of the third border 33, and / or the second end face 3332 is higher than the height of the first side face 334.

[0183] For example, in the thickness direction of the first portion 201, the surface of the first portion 201 may be lower than or flush with the surface of the first frame 13. In this case, when the first end 3311 contacts the first edge strip 131 of the first frame 13, the second edge strip 332 of the third frame 33 is spaced from the surface of the first portion 201, which helps to further reduce the possibility of the third frame 33 impacting the first portion 201, further improve the reliability of the electronic device 100, and thus improve the lifespan of the electronic device 100.

[0184] For example, in the thickness direction of the first portion 201, the surface of the first portion 201 may be higher than the surface of the first frame 13. In this case, the distance between the surface of the first portion 201 and the surface of the first frame 13 is less than the distance between the first end face 3312 and the first side face 334, so as to ensure that the first frame 13 does not collide with the first portion 201. The restriction on the first portion 201 is small, which is conducive to the diversified design of the flexible display screen 20.

[0185] Please refer to Figures 11 and 12. Figure 11 is a structural schematic diagram of the electronic device 100 shown in Figure 1 in some embodiments, and Figure 12 is a structural schematic diagram of the electronic device 100 shown in Figure 11 in some embodiments in its usage state.

[0186] The electronic device 100 shown in Figure 11 includes most of the technical features of the electronic device 100 shown in Figure 9. The following mainly describes the differences between the two, and the technical features that are the same in both will not be described again.

[0187] In some embodiments, the main difference between the electronic device 100 shown in FIG11 and the electronic device 100 shown in FIG9 lies in the configuration of the third border 33. Specifically, the first edge strip 331 of the third border 33 may not include the first transition surface 3313, and the first edge strip 331 of the third border 33 may not include the second transition surface 3333.

[0188] For example, the second side surface 335 and the first end surface 3312 can intersect, that is, the two are directly connected. The first end surface 3312 can be a plane, the first side surface 334 can be a plane, the second side surface 335 can be perpendicular to the first end surface 3312, and the first end surface 3312 can be flush with the first side surface 334.

[0189] For example, the third side surface 336 may intersect with the second end surface 3332, the second end surface 3332 may be a plane, the first side surface 334 may be a plane, and the second end surface 3332 and the first side surface 334 may be flush.

[0190] In this embodiment, the first side 334 and the second side 335 can be directly connected, and the first side 334 and the third side 336 can be directly connected, which is equivalent to not chamfering or rounding the corners of the third frame 33. As shown in Figure 12, when the third frame 33 contacts the first frame 13, the first end face 3312 can abut against the first edge strip 131 of the first frame 13, and the second end face 3332 can abut against the third edge strip of the first frame 13. Since there is no transition surface between the first end face 3312 and the second side 335, and there is no transition surface between the second end face 3332 and the third side 336, the areas of the first end face 3312 and the second end face 3332 can be larger. This is beneficial to have a larger contact area or contact size between the first end face 3312 and the first frame 13, and between the second end face 3332 and the first frame 13, thereby reducing the impact on the structure of the first frame 13 and the third frame 33 when they collide.

[0191] Please refer to Figures 13 and 14. Figure 13 is a structural schematic diagram of another electronic device 100 provided in an embodiment of this application, and Figure 14 is a structural schematic diagram of the electronic device 100 shown in Figure 13 in some embodiments in its usage state. The electronic device 100 of the embodiment in Figure 13 includes most of the technical features of the electronic device 100 of the embodiment in Figure 1. The same technical features between the two will not be described again in this embodiment. The following mainly describes the differences between the two.

[0192] The electronic device 100 of the embodiment shown in Figure 13 differs from the electronic device 100 of the embodiment shown in Figure 1 mainly in the arrangement of the housing device 10. In some embodiments, the electronic device 100 has a reverse closed state. In this case, the first angle α between the first housing 1 and the second housing 2 is smaller than the second angle b between the second housing 2 and the third housing 3, that is, the first housing 1 folds relative to the second housing 2 before the third housing 3. If the third housing 3 continues to be folded at this time, it is easy to damage the structure of the second pivot 5. Therefore, the second housing 2 and the third housing 3 should be folded after the electronic device 100 has been mistakenly folded to avoid damaging the electronic device 100.

[0193] In some embodiments, the housing device 10 is configured such that when the first housing 1 is folded relative to the second housing 2 and the second housing 2 is opened relative to the first housing 1, the first housing 1 is located on the side away from the edge of the second housing 2 and the center of the second pivot 5, away from the first pivot 4. The second pivot 5 is generally approximately symmetrical, and its centerline is generally located on its second main axis 52 (see Figure 6). For example, in the direction perpendicular to the second portion 203, the projection of the third housing 3 overlaps the projection of the second housing 2. In this case, because the first housing 1 is wider, its end is close to the second pivot 5, allowing the third housing 5 to directly abut against the end of the first housing 1, or the third housing 3 to abut against the end of the first housing 1 after rotating a small angle (0 to 90 degrees), thus preventing the third housing 3 from continuing to fold relative to the second housing 2, thereby reducing damage to the housing device 10. For example, the width of the first housing 1 can be greater than the width of the second housing 2 to achieve the above technical solution, but this is not strictly limited to this.

[0194] In some embodiments, the housing device 10 may be further configured such that when the first housing 1 is folded relative to the second housing 2 and the second housing 2 is opened relative to the first housing 1, the first housing 1 is located away from the edge of the second housing 2 and on the side of the second pivot 5 away from the first pivot 4. The side of the second pivot 5 away from the first pivot 4 may be the space between the fourth connecting portion 53 of the second pivot 5 (see FIG. 6) and the second side strip 332 of the third frame 33.

[0195] For example, in the direction perpendicular to the second part 203, the projection of the third housing 3 covers the projections of the second housing 2 and the second rotating shaft 5. At this time, since the first housing 1 is wider and its end is close to the second rotating shaft 5, the first housing 1 can directly abut against the third housing 3, preventing the second housing 2 and the third housing 3 from rotating relative to each other (i.e., preventing them from folding), thereby avoiding excessive force on the second rotating shaft 5 and thus improving the reliability of the electronic device 100.

[0196] In some embodiments, the first housing 1 further includes a protrusion 14, the arrangement of which can be referred to the relevant arrangements in the embodiments of Figures 1 to 12. In this embodiment, by providing the protrusion 14, it is beneficial to distinguish the structures of the first housing 1 and the third housing 3, thereby helping to avoid user misoperation.

[0197] In some embodiments, the top surface 140 of the protrusion 14 can be a plane, and the highest point of the protrusion 14 is located on the top surface 140 of the protrusion 14 in the thickness direction of the first housing 1. Referring to FIG14, when the protrusion 14 contacts the third frame 33, a portion of the top surface 140 of the protrusion 14 abuts against the first edge strip 331 of the third frame 33, and a portion of the top surface 140 of the protrusion 14 abuts against the third edge strip 333 of the third frame 33. For example, when the protrusion 14 contacts the third frame 33, a portion of the top surface 140 of the protrusion 14 abuts against the first edge strip 331 of the third frame 33, and a portion of the top surface 140 of the protrusion 14 abuts against the third edge strip 333 of the third frame 33. At this time, the first angle α between the first housing 1 and the second housing 2 can be smaller than the second angle b between the second housing 2 and the third housing 3, but is not limited thereto.

[0198] In this embodiment, the length of the protrusion 14 is basically the same as the length of the third housing 3. In this embodiment, the bending degree of the first housing 1 and the second housing 2 is greater than that of the second housing 2 and the third housing 3, which is beneficial for the protrusion 14 to abut against the third frame 33, thereby avoiding collision with the third part 205, thus protecting the third part 205 and improving the service life of the electronic device 100. In addition, since the top surface 140 of the protrusion 14 can abut against both the first edge strip 331 and the third edge strip 333 of the third frame 33 at the same time, the length of the protrusion 14 is relatively long, the abutment between the protrusion 14 and the third frame 33 is more stable, and the top surface 140 of the protrusion 14 is flat, which is beneficial for preventing other structures on the protrusion 14 from impacting the third part 205, making the protection of the flexible display screen 20 more reliable.

[0199] In some examples, the protrusion 14 may have a light-transmitting hole 141. The light-transmitting hole 141 may be located on the top surface 140 of the protrusion 14. The protrusion 14 can be used to mount a camera, with the camera exposed through the light-transmitting hole 141, i.e., on the top surface 140 of the protrusion 14. The light-transmitting hole 141 allows light to pass through, facilitating image formation by the camera. There can be multiple light-transmitting holes 141 to allow different lenses of the camera to capture images. Furthermore, mounting the camera on the protrusion 14 allows for the installation of larger or more cameras, thereby improving camera performance.

[0200] In some examples, the protrusion 14 may also have button holes 142. The button holes 142 may be located on the side of the protrusion 14 opposite to the first frame 13, but are not strictly limited to this. There may be multiple button holes 142. The button holes 142 are used to accommodate buttons, such as volume buttons, power buttons, etc.

[0201] It is understood that the protrusion 14 in this embodiment can be applied to the electronic device 100 in the embodiments of FIG1 to FIG12.

That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
