Detailed Implementation

[0028] The terms "first," "second," and "third," etc., used in this application specification, claims, and drawings are used to distinguish different objects, not to limit a specific order.

[0029] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0030] As related software and hardware technologies continue to develop and mature, more and more consumers are starting to use electronic devices such as foldable screen phones, and the market share of foldable screen phones and similar devices is likely to increase. However, there is still room for continuous improvement in the related technologies of foldable screen phones and similar electronic devices.

[0031] Among these technologies, foldable electronic devices, while achieving a larger display area when unfolded, have a screen ratio close to 1:1, which differs significantly from the original 16:9 ratio of typical videos, indicating that the screen's overall aspect ratio needs improvement.

[0032] Therefore, this application provides an electronic device and its housing assembly to improve the screen-to-body ratio. The electronic device can be configured as a mobile phone, tablet computer, etc.

[0033] In one implementation, Figure 1 This diagram illustrates the use of an embodiment of the electronic device 100 in the forward-looking direction. Figure 2This diagram illustrates the use of an embodiment of the electronic device 100 in the rear-viewing direction. The front-viewing direction can be understood as the direction from which the entire screen or more screens can be observed in a relatively unfolded state, while the rear-viewing direction is opposite to this front-viewing direction. It is understood that the front-viewing direction and the rear-viewing direction are relative concepts, primarily used to facilitate understanding of the corresponding implementation method. (Refer to...) Figure 1 , Figure 2 and Figure 3 The electronic device 100 includes a device housing 110 and a rollable screen 130; see reference Figure 3 and Figure 4 The device housing 110 may include a first housing 111, a second housing 112, a foldable mechanism 113, and an extension structure 120; wherein, the foldable mechanism 113 is connected between the first housing 111 and the second housing 112 so that the first housing 111 and the second housing 112 can be unfolded or overlapped relative to each other; wherein, the foldable mechanism 113 may be configured as a hinge mechanism, etc., and the hinge mechanism may include a swing arm, a synchronization mechanism, and a damping mechanism, etc.

[0034] The first housing 111 includes two opposing first housing surfaces and a second housing surface, wherein Figure 1 , Figure 2 The first and second shell surfaces are parallel to the plane of the drawing. Figure 3 The first shell surface and the second shell surface are arranged opposite to each other in the Z-axis direction; the first shell 111 also includes a shell side connecting the first shell surface and the second shell surface, for example... Figure 2 The left side and Figure 3 The upper position (see X1 position); wherein, the housing side is located on the side of the first housing 111 away from the foldable mechanism 113, for example, located at the upper end position (see X1 position); Figure 4 The right side of the figure. The extended structure 120 includes an abutting side, which can be seen, for example, at position X1 in the figure. The extended structure 120 is movably connected to the first housing 111, for example, by means of a guide rail structure; the extended structure 120 is configured to move along a first direction so that the abutting side moves away from the housing side of the device housing 110, the first direction intersecting the normal of the first housing surface; wherein, the normal of the first housing surface can be set to be perpendicular to the normal of the first housing surface. Figure 1 , Figure 2 In the diagram, the normal to the first shell surface can also be set to... Figure 3 The Z-axis direction in the figure; correspondingly, the first direction can be set as the X-axis direction in the figure. (Refer to...) Figure 1 , Figure 2 and Figure 3 The extended structural member 120 is configured to move along a first direction X so that the abutting side moves away from the housing side of the device housing 110, for example, from position X1 to position X2 in the figure.

[0035] The rollable screen 130 is rolled up outside the abutting side. This can be understood as the rolled portion of the rollable screen 130 covering a portion of the abutting side of the extended structural member 120, so that the rollable screen 130 forms a first screen portion 131 and a second screen portion 132 on the first and second shell surfaces, respectively. It is understood that the portion of the rollable screen 130 rolled up outside the abutting side can be configured as a flexible screen. The rollable screen 130 also includes a third screen portion 133 connected to the first screen portion 131. The third screen portion 133 is opposite to and connected to the second shell 112. The connection between the third screen portion 133 and the second shell 112 can be a fixed connection or a connection with a relatively small range of motion. Furthermore, the first screen portion 131 and the third screen portion 133 can be integrally formed. It is understood that the third screen portion 133, the first screen portion 131, and the second screen portion 132 can be sequentially connected using integral forming or other methods. The second screen portion 132 is movably connected to the extended structure 120. This can be understood as the second screen portion 132 having a relatively large range of motion relative to the extended structure 120. For example, a guide rail structure or a sliding groove structure can be used to achieve the movable connection between the second screen portion 132 and the extended structure 120. The abutting side of the extended structure 120 is used to abut against the inner side of the rolled portion of the rollable screen 130 along the first direction. For example, the rolled portion of the rollable screen 130 is pushed from position X1 in the figure to position X2 by abutting.

[0036] The connection between the third screen portion 133 and the first screen portion 131 is configured to be foldable and positioned opposite the foldable mechanism 113. For example, the connection between the third screen portion 133 and the first screen portion 131 can be configured as a flexible screen, or the entire rollable screen 130, including the first screen portion 131, the second screen portion 132, and the third screen portion 133, can be configured as a flexible screen. (Refer to...) Figure 3In the left-hand diagram, with the first housing 111 and the second housing 112 stacked relative to each other, the second housing 112 is positioned opposite to the surface of the second housing and covers at least a portion of the second screen portion 132. This can be understood as the electronic device 100 being configured as an outward-folding device, with most of the screen of the electronic device 100 located on the outer side in the stacked state. For example, in the stacked state, at least the first screen portion 131 and the third screen portion 133 are located on the outer side. Of course, in the stacked state, the second screen portion 132 can also be pushed outward by extending the outward-extending structural member 120 to increase the display area in the stacked state. The camera module of the electronic device 100 can be at least partially located on the side of the second housing 112 facing the third screen portion 133, so that in the stacked state, the second screen portion 132 can be used to display the viewfinder image of the camera module, utilizing both the first screen portion 131 and the second screen portion 132, which is beneficial for magnifying the details of the scene in the viewfinder image. For example, the rear camera can be positioned on the side of the second housing 112 facing the third screen portion 133, and the front camera can be positioned on the side of the first housing 111 facing the first screen portion 131 or on the side of the first housing 111 facing the second screen portion 132.

[0037] In addition, refer to Figure 1 When the first screen portion 131 faces the user, the rear camera can be positioned on the left side of the first screen portion 131. Of course, in other embodiments, when the first screen portion 131 faces the user, the rear camera can also be positioned on the right side of the first screen portion 131, and this embodiment does not limit this.

[0038] In this embodiment, by connecting the foldable mechanism 113 between the first housing 111 and the second housing 112, and configuring the connection portion between the third screen portion 133 and the first screen portion 131 as foldable and disposed opposite to the foldable mechanism 113, the electronic device 100 can have a large display area through the first screen portion 131 and the third screen portion 133 in a relatively unfolded state; in a state where the first housing 111 and the second housing 112 are relatively stacked, the second housing 112 is disposed opposite to the second housing surface and the second housing 112 covers at least a portion of the second screen portion 132, thereby enabling the first screen portion 131 and the third screen portion 132 to be stacked in a relatively stacked state. The third screen portion 133 faces outwards and can provide display images to the user, increasing the overall display area in the relatively stacked state; the abutting side is used to abut the inner side of the rolled portion of the rollable screen 130 along the first direction, so that the second screen portion 132 can be extended to be coplanar with the first screen portion 131 and the third screen portion 133 through the extension action of the extension structure 120. This is beneficial to improve the display ratio of the electronic device 100 through the first screen portion 131, the second screen portion 132 and the third screen portion 133, for example, changing the display ratio of the screen from close to 1:1 to close to the original ratio of general video 16:9, which is beneficial to increase the screen ratio of the display.

[0039] In addition, the abutting side of the extended structural member 120 abuts against the inner side of the rolled portion of the rollable screen 130, which improves space utilization between the first screen portion 131 and the second screen portion 132 and helps to reduce the overall thickness of the electronic device 100.

[0040] In some implementations, refer to Figure 2 The electronic device 100 also includes a connecting strip 180, which extends along the extension direction of the side of the housing, for example along... Figure 2 The Y-direction extension is provided; the connecting strip 180 is fixedly connected to the edge of the second screen portion 132, for example, by adhesive bonding or snap-fit ​​connection. The connecting strip 180 is movably connected to the extended structural member 120, thereby reducing the risk of the second screen portion 132 being damaged by pulling through the connecting strip 180. The movable connection between the second screen portion 132 and the extended structural member 120 can be achieved using a guide rail structure, a sliding groove structure, or other similar structures.

[0041] In some embodiments, the second housing 112 has a third housing surface, for example Figure 3 The left side surface of the shell; in the state where the first shell 111 and the second shell 112 are unfolded relative to each other, the third shell surface is located on the same side of the first shell 111 as the first shell surface, for example... Figure 3In the middle diagram, the third shell surface and the first shell surface are respectively located on the left side of the first shell 111; wherein, the third screen part 133 is arranged opposite to the third shell surface, thereby improving the installation convenience of the third screen part 133; wherein, the third screen part 133 can be attached to the third shell surface, including the form in which the third screen part 133 and the third shell surface can move relative to each other, or the third screen part 133 and the third shell surface are bonded and fixed.

[0042] In some embodiments, the device housing 110 further includes an abutment protrusion disposed on one of the first housing 111 and the second housing 112; when the first housing 111 and the second housing 112 are stacked relative to each other, the abutment protrusion abuts against the other of the first housing 111 and the second housing 112, so that at least a portion of the second screen portion 132 is spaced apart from the second housing 112. The abutment protrusion may be disposed on the first housing 111, and when the first housing 111 and the second housing 112 are stacked relative to each other, the abutment protrusion abuts against the second housing 112; alternatively, the abutment protrusion may be disposed on the second housing 112, and when the first housing 111 and the second housing 112 are stacked relative to each other, the abutment protrusion abuts against the first housing 111. In this embodiment, refer to... Figure 3 As shown in the left figure, when the electronic device 100 is in a relatively stacked state and the second screen portion 132 is relatively retracted (which can be understood as the second screen portion 132 not being pushed outward by the outward structure 120), the second screen portion 132 can reduce the risk of being damaged by bumps by abutting the protrusion.

[0043] In some implementations, refer to Figure 4 and Figure 5 The device housing 110 is provided with at least two circuit elements 140. In a second direction intersecting the normal and the first direction of the first housing surface, at least one of the circuit elements 140 and the device housing 110, or between two adjacent circuit elements 140, forms a first receiving gap 151. For example, the first receiving gap 151 can be formed between the circuit element 140 and the device housing 110, or it can be formed between two adjacent circuit elements 140. For example, the first housing surface can be configured to be parallel to... Figure 4 In the diagram, the normal to the first shell surface can be set to be perpendicular to... Figure 4 In the diagram, the first direction can be set along the X direction, and the second direction can be set along the Y direction. Furthermore, circuit element 140 can be configured as a battery, circuit board, speaker, microphone, camera module, etc.; for example, in... Figure 4In the circuit, the circuit element 140 may include components such as the first battery 141, the first circuit board 142, the second circuit board 143, and the second battery 144. A drive assembly 160 is provided on the device housing 110. The drive assembly 160 can be understood as a component that provides driving force to external components. The drive assembly 160 is connected to the device housing 110, for example, the drive assembly 160 is mounted on the device housing 110. The drive assembly 160 is at least partially disposed within the first receiving gap 151, including both partially and completely disposed within the first receiving gap 151. The drive assembly 160 is driveably connected to the extended structural member 120, for example, through a gear structure, linkage mechanism, etc., so that the abutting side of the extended structural member 120 moves away from the outer side of the device housing 110, for example, so that the abutting side of the extended structural member 120 moves away from the housing side. Figure 3 The X1 position is moved to the X2 position. In this embodiment, the drive component 160 is at least partially disposed within the first receiving gap 151, which improves the space utilization of the electronic device 100 and helps to further reduce the overall thickness of the electronic device 100. Since the rollable screen 130 is rolled around the abutting side of the extended structure 120 to form the first screen body portion 131 and the second screen body portion 132, the first receiving gap 151 can be disposed on the first housing 111, and the drive component 160 can be correspondingly connected to the first housing 111. Compared with the first receiving gap 151 being disposed on the second housing 112 and the drive component 160 being connected to the second housing 112, the first receiving gap 151 being disposed on the first housing 111 and the drive component 160 being connected to the first housing 111 can reduce the overall length of the transmission structure between the drive component 160 and the extended structure 120, and can reduce the need for the transmission structure to pass through the aforementioned foldable mechanism 113, thereby reducing structural complexity and improving the reliability of the electronic device 100.

[0044] In some implementations, refer to Figure 4 and Figure 5 ,or Figure 6 , Figure 7 and Figure 8 In the first direction X, at least one of the circuit element 140 and the device housing 110, and at least one of the side regions of the device housing 110, forms a second receiving gap 152, including the formation of the second receiving gap 152 between the circuit element 140 and the device housing 110, and the formation of the second receiving gap 152 in the side regions of the device housing 110. For example, Figure 5The second receiving gap 152 is formed on the side area of ​​the first housing 111. It can be understood that the second receiving gap 152 is set on the first housing 111, thereby reducing the overall length of the transmission structure between the drive assembly 160 and the extension structure 120, and reducing the need for the transmission structure to pass through the foldable mechanism 113, thus reducing the structural complexity and improving the reliability of the electronic device 100.

[0045] The second accommodating gap 152 is connected to the first accommodating gap 151; a part of the driving component 160 is disposed in the first accommodating gap 151, and another part of the driving component 160 is disposed in the second accommodating gap 152, thereby further improving the space utilization of the electronic device 100 and helping to further reduce the overall thickness of the electronic device 100.

[0046] In some implementations, refer to Figure 5 The drive assembly 160 includes a first guide body 161 and a moving block 162. The first guide body 161 can be configured as a lead screw, and the moving block 162 can be configured as a nut; or the first guide body 161 can be configured as a linear slide, and the moving block 162 can be configured as a slide seat. The first guide body 161 is disposed within a first receiving gap 151. The first guide body 161 and the first receiving gap 151 extend along a first direction X, which can be understood as the length direction of the first guide body 161 and the length direction of the first receiving gap 151 being along the first direction X, respectively. The moving block 162 is movably connected to the first guide body 161 and is configured to move along the extension direction of the first guide body 161. The moving block 162 is connected to the extended structural member 120, thereby enabling the movement of the extended structural member 120 through the first guide body 161 and the moving block 162, further improving the space utilization of the electronic device 100 and helping to further reduce the overall thickness of the electronic device 100.

[0047] In some embodiments, the drive assembly 160 further includes a second guide body 163, which may be correspondingly configured as a guide rod, another linear slide, etc.; the second guide body 163 is disposed within the first receiving gap 151, and extends along the first direction X, which can be understood as the length direction of the second guide body 163 being along the first direction X; in addition, the moving block 162 is also movably connected to the second guide body 163 along the first direction X, which can be understood as the moving block 162 being movable relative to the second guide body 163; the first guide body 161 and the second guide body 163 are arranged side by side along the arrangement direction of the first shell surface and the second shell surface, for example, the first shell surface and the second shell surface are arranged along... Figure 3 , Figure 5 The first guide body 161 and the second guide body 163 are arranged in the Z direction, and are arranged along the Z direction. Figure 5The Z-direction arrangement further improves the space utilization of the electronic device 100, which is conducive to further reducing the overall thickness of the electronic device 100. Of course, the first guide body 161 and the second guide body 163 can also be arranged side by side along the surface of the first shell and respectively disposed in the first receiving gap 151, which is also conducive to improving the space utilization of the electronic device 100 and reducing the overall thickness of the electronic device 100.

[0048] In some implementations, refer to Figure 5 The drive assembly 160 also includes a drive body 164, which can be configured as a drive motor, drive cylinder, etc. The drive body 164 is connected to the moving block 162 via a transmission, for example, through a gear set, linkage mechanism, cam mechanism, crank-slider mechanism, etc. The length direction of the drive body 164 is set along the first direction X, and the drive body 164 is set within the first accommodating gap 151, thereby further improving the space utilization of the electronic device 100 and helping to further reduce the overall thickness of the electronic device 100.

[0049] In some alternative implementations, refer to Figure 6 , Figure 7 and Figure 8 When the first guide body 161 extends along the first direction X, the length direction of the drive body 164 can be set along the second direction Y. The drive body 164 is set in the second accommodating gap 152, thereby further improving the space utilization of the electronic device 100 and helping to further reduce the overall thickness of the electronic device 100.

[0050] In some embodiments, the drive body 164 is connected to the end of the first guide 161 away from the housing side, for example, with Figures 5 to 8 The left side of the first housing 111 is connected, allowing it to be closer to the foldable mechanism 113. The circuit element 140 includes a first battery 141 and a first circuit board 142 disposed on the first housing 111, and a second circuit board 143 disposed on the second housing 112. The first circuit board 142 and the second circuit board 143 can be configured as printed circuit boards (PCBs). The first battery 141 is electrically connected to the drive body 164 to supply power to the drive body 164. The second circuit board 143, the first circuit board 142, and the drive body 164 are sequentially connected to transmit drive signals to the drive body 164, thereby reducing the number of wires required for the drive body 164, which helps to improve the simplicity of the electrical connections of the electronic device 100 and improves electrical safety.

[0051] In some implementations, refer to Figure 4The second circuit board 143 has a first notch 145, which can be understood as the second circuit board 143 being C-shaped or open in general; the second battery 144 is at least partially disposed within the first notch 145, thereby further improving space utilization.

[0052] In some embodiments, the second circuit board 143 may be configured as a strip and disposed next to the second battery 144, thereby further improving space utilization.

[0053] In some implementations, refer to Figure 9 A rotating shaft 121 is provided on the abutting side, and the rotating shaft 121 is rotatably connected to the extended structural member 120; the axis of rotation of the rotating shaft 121 is parallel to the extension direction of the abutting side, for example, after the rotating shaft 121 is rotatably connected to the extended structural member 120, the axis of rotation of the rotating shaft 121 is perpendicular to the direction of rotation of the abutting side. Figure 9 The peripheral wall of the pivot 121 is used to abut against the rolled portion of the rollable screen 130, thereby reducing frictional wear on the rolled portion of the rollable screen 130 and improving the service life of the rollable screen 130 and the electronic device 100.

[0054] In some implementations, refer to Figure 9 The second screen portion 132 includes a screen side 134, which is located on the side of the second screen portion 132 away from the first screen portion 131; wherein the connecting strip 180 can be connected to the screen side 134. A synchronization mechanism 170 is provided on the device housing 110, which connects the device housing 110 and the second screen portion 132 respectively, for example, connecting the first housing 111 and the second screen portion 132 respectively. Specifically, it can be configured to connect the shell structure member 114 on the first housing 111 and the connecting strip 180 on the screen side 134 of the second screen portion 132 respectively; the synchronization mechanism 170 is configured such that when it moves closer to the foldable mechanism 113 (e.g., towards the side), it... Figure 9 In the case of the lower side moving), the screen side 134 moves toward the foldable mechanism 113 (e.g., toward the lower side). Figure 9 The lower side of the device moves (the second screen portion 132 moves), allowing it to retract smoothly along with the retraction of the extended structure 120, thus improving the ease of use of the electronic device 100. Of course, without this synchronization mechanism 170, the user can manually retract the second screen portion 132 to reduce the overall cost of the electronic device 100.

[0055] In some implementations, refer to Figure 9The synchronization mechanism 170 includes a first rope assembly, which includes a first rope body 171 and a first pulley assembly 172. The first pulley assembly 172 includes at least one pulley. The two ends of the first rope body 171 are respectively connected to the device housing 110 and the second screen portion 132. The first rope body 171 abuts against the peripheral wall of the first pulley assembly 172 (which can be understood as the first rope body 171 changing the direction of the rope and the direction of the force by passing through the peripheral wall of the first pulley assembly 172), so that when it moves closer to the foldable mechanism 113 on the abutment side (e.g., towards...). Figure 9 In the case of the lower side moving), the first rope 171 causes the screen side 134 to move in the direction of the foldable mechanism 113 (e.g., towards). Figure 9 (Moves to the lower side of the middle), thereby enabling the second screen portion 132 to retract smoothly with the retraction of the extended structure 120 via the first rope 171 and the first pulley group 172, and facilitating the reduction of the overall volume of the electronic device 100 via the first rope 171 and the first pulley group 172.

[0056] In some implementations, refer to Figure 10 The synchronization mechanism 170 includes a second rope assembly; the second rope assembly includes a second rope body 173 and a second pulley group 174, the second pulley group 174 includes at least one pulley, and the two ends of the second rope body 173 are respectively connected to the device housing 110 and the second screen body portion 132; the second rope body 173 abuts against the peripheral wall of the second pulley group 174 (which can be understood as the second rope body 173 changing the direction of the rope and the direction of the force through the peripheral wall of the second pulley group 174), so that when the abutment side moves away from the foldable mechanism 113 (e.g., towards...). Figure 9 In the case of the upper side moving), the second rope 173 causes the screen side 134 to move in a direction away from the foldable mechanism 113 (e.g., towards). Figure 9 (Move the upper side of the middle), which helps to improve the movement stability of the second screen part 132 during the extension process.

[0057] In some implementations, refer to Figure 9 , Figure 10 and Figure 11 The device housing 110 is also provided with an end cover 175, which is located on one end of the extended structure 120 along the extension direction of the abutting side. The synchronization mechanism 170 is at least partially located between the extended structure 120 and the end cover 175, thereby reducing the risk of dust accumulation and scratching of the user by the synchronization mechanism 170.

[0058] In some embodiments, the first rope assembly and the second rope assembly are provided at the same end of the extended structure 120 along the extension direction of the abutting side. The end cap 175 covers at least a portion of the first rope assembly and at least a portion of the second rope assembly, which helps to further reduce the risk of dust accumulation and user scratches in the synchronization mechanism 170. In addition, the provision of the first rope assembly and the second rope assembly at the same end of the extended structure 120 can improve the overall movement stability of the second screen portion 132 during extension and retraction.

[0059] In some embodiments, the aforementioned synchronization mechanism 170 is provided at both ends of the extended structural member 120 along the extension direction of the abutting side, and the end cap 175 is fixedly connected to the extended structural member 120, thereby improving the movement stability of the second screen body portion 132 during the retraction and extension processes. The end cap 175 and the extended structural member 120 can be fixedly connected by means of adhesive bonding, screws, or other fasteners.

[0060] In some embodiments, one of the extension structure 120 and the shell structure 114 is provided with a second notch, and the other of the extension structure 120 and the shell structure 114 is at least partially disposed within the second notch, thereby reducing the overall thickness of the electronic device 100.

[0061] In some embodiments, the device housing 110 includes the aforementioned shell structure 114, wherein the shell structure 114 may be disposed on the first housing 111; the shell structure 114 is provided with a first battery 141, and the extended structure 120 is movably connected to the shell structure 114, thereby improving the overall connection stability of the first housing 111.

[0062] In some implementations, refer to Figure 12 The extended structural member 120 is disposed on the side of the shell structural member 114 facing away from the first battery 141. This can be understood as the shell structural member 114 and the extended structural member 120 being arranged in layers, for example, the shell structural member 114 and the extended structural member 120 being respectively configured as plates. The side of the extended structural member 120 facing the shell structural member 114 abuts against the shell structural member 114, thereby increasing the movement stability of the extended structural member 120 and the shell structural member 114 during relative movement, thus improving the movement stability of the extended structural member 120 and the second screen portion 132 during the retraction and extension processes.

[0063] In some embodiments, a second battery 144 is also provided on the second housing 112, and the second battery 144 is connected to the second housing 112; the second housing 112 includes a cover 190, which is separately disposed from the second housing 112 and is connected to the side of the second housing 112 facing away from the third screen portion 133. In this embodiment, it is advantageous to prioritize the installation of the third screen portion 133 onto the second housing 112 during installation, and to perform maintenance by removing the cover 190, thereby reducing the need to disassemble the third screen portion 133 and lowering the risk of damage to the rollable screen 130.

[0064] Furthermore, referring to the above analysis, this application also provides a housing assembly for the aforementioned electronic device 100, the housing assembly including the aforementioned device housing 110. The device housing 110 may include a first housing 111, a second housing 112, a folding mechanism 113, and an extension structure 120; wherein, the folding mechanism 113 is connected between the first housing 111 and the second housing 112, so that the first housing 111 and the second housing 112 can be unfolded or overlapped relative to each other. The first housing 111 includes two opposing first housing surfaces and a second housing surface. The first housing 111 also includes a housing side connecting the first housing surface and the second housing surface. The extended structural member 120 includes an abutting side, which is located on the side of the first housing 111 away from the foldable mechanism 113. The extended structural member 120 is movably connected to the first housing 111 and configured to move along a first direction X so that the abutting side moves away from the housing side towards the outside of the device housing 110. The first direction X intersects the normal of the first housing surface, and the abutting side is used to abut against the inner side of the rolled portion of the rollable screen 130 along the first direction X. When the first housing 111 and the second housing 112 are stacked, the second housing 112 is disposed opposite to the second housing surface of the first housing 111, thereby covering at least a portion of the second screen portion 132.

[0065] In this embodiment, by connecting the foldable mechanism 113 between the first housing 111 and the second housing 112, the housing assembly can, in its relatively unfolded state, allow the corresponding electronic device 100 to have a larger display area through the first screen portion 131 and the third screen portion 133. When the first housing 111 and the second housing 112 are stacked, the second housing 112 is positioned opposite to the second housing surface, thereby enabling the corresponding first screen portion 131 and third screen portion 133 to face outwards and provide a display screen to the user in the stacked state, which is beneficial for increasing the display area in the stacked state. The overall display area; the abutting side is used to abut the inner side of the rolled portion of the rollable screen 130 along the first direction, so that the corresponding second screen portion 132 can be extended to be coplanar with the first screen portion 131 and the third screen portion 133 through the extension action of the extension structure 120. This is beneficial for the corresponding electronic device 100 to improve the display ratio of the electronic device 100 through the first screen portion 131, the second screen portion 132 and the third screen portion 133, for example, changing the display ratio of the screen from close to 1:1 to close to the original ratio of general video 16:9, which is beneficial to increase the screen ratio.

Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the protection scope of this application. The protection scope of this application should be determined by the protection scope of the claims.
