Description

Technical Field

[0001] The present application belongs to the field of electronic technology, and specifically relates to an electronic device. Background Art

[0002] With the rapid development of electronic technology, people's use and demand for electronic devices are getting higher and higher. In order to adapt to users' usage needs in different scenarios such as games and video playback, the display screen size of electronic devices is also getting larger and larger. Curled screens are very popular among users due to their scalability and portability.

[0003] The screen of a roll-up screen generally adopts a flexible screen. In order to improve the supporting strength of the roll-up screen when it is expanded, the support is achieved under the screen through the comb-tooth structure of the shell on both sides.

[0004] Existing rollable displays use under-screen fingerprint unlocking, but the fingerprint recognition area is obscured by the comb-teeth structure. To prevent this from affecting the fingerprint recognition area, the comb-teeth in the steel sheet are often partially hollowed out. However, this solution leaves the fingerprint recognition area and its surroundings without the steel support, significantly reducing the support strength of the rollable display. Prolonged contact with this area can easily cause the screen to sag, potentially damaging it and impacting the user experience. Summary of the Invention

[0005] The present application aims to provide an electronic device that at least solves one of the problems in the prior art of low support strength near the fingerprint recognition area under the curved screen.

[0006] In order to solve the above technical problems, this application is implemented as follows:

[0007] In a first aspect, an embodiment of the present application provides an electronic device, including:

[0008] a housing, the housing comprising a first supporting structure, a second supporting structure, and an auxiliary supporting structure, the first supporting structure and the second supporting structure being movably connected, and an opening being defined between the first supporting structure and the second supporting structure;

[0009] a functional module, the functional module being arranged at the opening;

[0010] The auxiliary supporting structure is exposed at the opening, and when the first supporting structure moves relative to the second supporting structure, the area of the auxiliary supporting structure exposed at the opening increases.

[0011] In an embodiment of the present application, an opening is formed between the first supporting structure and the second supporting structure, and the auxiliary supporting structure and the functional module are both arranged at the opening, wherein the area of the auxiliary supporting structure exposed at the opening changes with the relative movement of the first supporting structure and the second supporting structure, ensuring that the functional module will not be blocked when the electronic device is in the expanded state and the closed state, and can form a strong support at the opening, thereby avoiding repeated operation of the functional module causing cracks at the corresponding opening of the display screen.

[0022] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] The features of the terms "first" and "second" in the specification and claims of this application may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, the meaning of "plurality" is two or more.

[0024] In the description of this application, it should be understood that the terms "up", "down", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on this application.

[0025] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0026] In existing technology, the screen of a rollable screen phone is generally supported by two casings with steel combs. To prevent the support structure from affecting the fingerprint recognition area, the steel combs in the fingerprint recognition area are often partially hollowed out. However, this means that the fingerprint recognition area and its surrounding area lack steel support, reducing the support strength of the rollable screen.

[0027] In order to solve the above problems, the following Figures 1-6 The electronic device according to the embodiments of the present application is described. The electronic device described in the embodiments of the present application includes, but is not limited to, any of a smartphone, tablet, computer, and smart wearable device. Those skilled in the art can select and configure the device according to the circumstances. Optionally, the electronic device is a roll-up screen mobile phone.

[0028] like Figure 1 and Figure 2 As shown, an electronic device according to some embodiments of the present application includes: a housing 10 and a functional module 30. The housing 10 includes a first supporting structure 11, a second supporting structure 12 and an auxiliary supporting structure 13, and the first supporting structure 11 and the second supporting structure 12 are movably connected. Specifically, the first supporting structure 11 and the second supporting structure 12 are slidably connected. There is an opening 20 between the first supporting structure 11 and the second supporting structure 12. The functional module 30 is provided at the opening 20. The auxiliary supporting structure 13 is exposed at the opening 20, and when the first supporting structure 11 moves away from the second supporting structure 12 relative to the second supporting structure 12, the area of the auxiliary supporting structure 13 exposed at the opening 20 increases.

[0029] The housing 10 is a supporting structure of the electronic device, and is used to mount the display screen 40. The first supporting structure 11 includes a plurality of first clamping claws 111, and the second supporting structure 12 includes a plurality of second clamping claws 121. The first clamping claws 111 and the second clamping claws 121 are arranged in an alternating manner. Figure 1 and Figure 2 As shown, the first clamping jaw 111 is inserted between two adjacent second clamping jaws 121, and the second clamping jaw 121 is inserted between two adjacent first clamping jaws 111. During the sliding process of the first support structure 11 relative to the second support structure 12, the electronic device switches between the folded state and the expanded state. The multiple first clamping jaws 111 and the multiple second clamping jaws 121 are interlocked to provide stable support for the electronic device.

[0030] To prevent the functional module 30 from affecting the travel of the first support structure 11 and the second support structure 12 when the first support structure 11 and the second support structure 12 move relative to each other, an opening 20 is provided between the first support structure 11 and the second support structure 12. The functional module 30 is a functional device such as a fingerprint module or a camera module, and is disposed in the opening 20. Optionally, the width of the opening 20 is the same as or slightly larger than the width of the functional module 30. Optionally, the first support structure 11 and the second support structure 12 are steel sheet structures, and correspondingly, the multiple first clamping jaws 111 and the multiple second clamping jaws 121 are each steel sheet comb teeth.

[0031] An auxiliary support structure 13 is provided at the opening 20 to provide support and prevent significant deformation of the display screen 40 of the electronic device during the pressing of the functional module 30, which could affect its service life. It is understood that the auxiliary support structure 13 can be independently driven or driven by the same drive as the relative movement of the first support structure 11 and the second support structure 12.

[0032] In an optional embodiment, when the first support structure 11 moves relative to the second support structure 12 in a direction away from the second support structure 12, the area of the opening 20 gradually increases, and the area of the auxiliary support structure 13 exposed at the opening 20 increases synchronously therewith. Specifically, there is a linear relationship between the increase in the area of the opening 20 and the area of the auxiliary support structure exposed. In another optional embodiment, when the first support structure 11 moves relative to the second support structure 12 in a direction away from the second support structure 12, the area of the opening 20 increases, and the area of the auxiliary support structure 13 increases only after the area of the opening 20 increases to a limit. That is, as long as the area of the auxiliary support structure 13 exposed at the opening 20 increases, it is sufficient, and it does not need to increase synchronously with the increase in the area of the opening 20. In another optional embodiment, the area of the auxiliary support structure 13 is simultaneously driven to increase during the relative movement of the first support structure 11 and the second support structure 12, thereby increasing the area of the auxiliary support structure 13 exposed at the opening 20.

[0033] Specifically, the functional module 30 is disposed near the right side of the opening 20. The auxiliary support structure 13 is disposed on the left side of the opening 20. Of course, the auxiliary support structures 13 may also be disposed on opposite sides of the functional module 30, as long as the exposed area of the auxiliary support structure 13 at the opening 20 can be increased when the first support structure 11 moves relative to the second support structure 12.

[0034] The electronic device provided in the embodiment of the present application forms an opening 20 between the first supporting structure 11 and the second supporting structure 12, and the auxiliary supporting structure 13 and the functional module 30 are both arranged at the opening 20, wherein the area of the auxiliary supporting structure 13 exposed at the opening 20 changes with the relative movement of the first supporting structure 11 and the second supporting structure 12, thereby ensuring that the functional module 30 will not be blocked when the electronic device is in the expanded state and the closed state, and can form a strong support at the opening 20, thereby preventing the functional module 30 from being broken at the opening 20 due to repeated use.

[0035] In a specific embodiment of the present application, when the first supporting structure 11 moves relative to the second supporting structure 12 in a direction away from the second supporting structure 12, the area of the opening 20 gradually increases, and the area of the auxiliary supporting structure 13 exposed by the opening 20 increases as the area of the opening 20 increases.

[0036] Among them, such as Figure 2 As shown, when the first support structure 11 moves relative to the second support structure 12 in a direction away from the second support structure 12, the area of the opening 20 increases, and the auxiliary support structure 13 expands to support the increased area of the opening 20. Figure 1 As shown, when the first supporting structure 11 moves relative to the second supporting structure 12 toward the second supporting structure 12 , the area of the opening 20 is reduced and the auxiliary supporting structure 13 contracts to avoid affecting the relative movement of the first supporting structure 11 and the second supporting structure 12 .

[0037] In the electronic device provided in the embodiments of the present application, the exposed area of the auxiliary support structure 13 at the opening 20 adjusts with the relative movement of the first support structure 11 and the second support structure 12. This allows timely support to be provided at the opening 20 as the area of the opening 20 increases, without affecting the relative movement of the first support structure 11 and the second support structure 12. Furthermore, during the relative movement of the first support structure 11 and the second support structure 12, the auxiliary support structure 13 adjusts synchronously with the changes in the area of the opening 20, providing real-time support and avoiding the potential safety hazard of lack of support at the opening 20 during the relative movement of the first support structure 11 and the second support structure 12.

[0038] like Figure 3 and Figure 5 As shown, the electronic device further includes a display screen 40, which is disposed within the housing 10 and covers the opening 20. The auxiliary support structure 13 includes a support belt 131 and a drive mechanism 132 for driving the support belt 131. The support belt 131 is exposed at the opening 20 to support the display screen 40. When the first support structure 11 moves relative to the second support structure 12, the drive mechanism 132 drives the support belt 131 to move, thereby increasing the area of the support belt 131 exposed at the opening 20.

[0039] Specifically, the display screen 40 is a rollable screen, and the display screen 40 is arranged on the housing 10 to cover the opening 20. The functional module 30 is located below the display screen 40, and the functional module 30 can be operated by touching the position corresponding to the functional module 30 on the display screen 40. When the first support structure 11 moves away from the second support structure 12 relative to the second support structure 12, the display screen 40 gradually unfolds, and the driving member 137 drives the support belt 131 to unfold to support the extended area of the display screen 40. When the first support structure 11 moves toward the second support structure 12 relative to the second support structure 12, the display screen 40 gradually closes, and the driving member 137 drives the support belt 131 to retract to avoid affecting the closure of the display screen 40.

[0040] In another specific embodiment of the present application, there is no need to set up a driving mechanism 132, and the first support structure 11 and the second support structure 12 move while driving the support belt 131 to move. For example, a mounting hole is provided on the first clamping jaw 111 of the first support structure 11. One end of the support belt 131 is fixedly connected to the second clamping jaw 121, and the other end is sleeved on the connecting shaft, and the opposite ends of the connecting shaft are respectively fixedly inserted into the mounting holes on the corresponding sides. The support belt 131 is retractable and can be extended and retracted with the relative movement of the first support structure 11 and the second support structure 12. Of course, other structural designs can also be adopted, as long as the support belt 131 can be extended and retracted with the movement of the first support structure 11 or the second support structure 12.

[0041] It can be understood that when the first support structure 11 and the second support structure 12 move relative to each other, the opening 20 increases, and the support belt 131 moves synchronously under the action of the driving mechanism 132, or, after the opening 20 increases to a limit value, the support belt 131 moves under the action of the driving structure.

[0042] In the electronic device provided in the embodiment of the present application, when the first supporting structure 11 and the second supporting structure 12 move relative to each other, the exposed area of the supporting belt 131 at the opening 20 increases, thereby providing support for the opening 20 with the help of the supporting belt 131.

[0043] In one embodiment of the present application, the support belt 131 includes a plurality of support plates 136. Two adjacent support plates 136 are rotatably connected to allow the support belt 131 to be flexibly accommodated within the housing 10. Alternatively, a support plate 136 can be telescopically mounted on another adjacent support plate 136, thereby allowing the support belt 131 to be extended and positioned within the opening 20. One end of the support belt 131 is connected to a drive mechanism 132, and the other end of the support belt 131 is connected to the housing 10. When the first support structure 11 moves relative to the second support structure 12, the drive mechanism 132 drives the support belt 131 to move, thereby increasing the number of support plates 136 exposed within the opening 20.

[0044] In a specific embodiment of the present application, Figure 4 and Figure 6As shown, the support belt 131 includes multiple support plates 136, which are rotatably connected in sequence via hinges. When the first support structure 11 moves relative to the second support structure 12 to unfold the display screen 40, the drive mechanism 132 drives one end of the support belt 131 to move beneath the display screen 40, so that the support belt 131 fills the increased space in the opening 20 during the unfolding of the display screen 40, providing support for the increased area of the display screen 40. Specifically, the ends of the support plates 136 are rotatably connected via hinges. The support plate 136 at one end of the support belt 131 is connected to the housing 10 to achieve relative fixation between the housing 10 and the support plate 136. The support plate 136 at the other end of the support belt 131 is connected to the drive mechanism 132. Under the action of the drive mechanism 132, the support plate 136 drives the next support plate 136 via the hinge to achieve the extension and bending of the support belt 131. It should be noted that the end of the support belt 131 can be connected to either the first support structure 11 or the second support structure 12 within the housing 10. When the first supporting structure 11 moves relative to the second supporting structure 12 , the number of the supporting plates 136 exposed at the opening 20 increases, thereby increasing the area of the auxiliary supporting structure 13 exposed at the opening 20 .

[0045] The sizes of the support plates 136 can be the same or different. For example, the support plates 136 provided at the portion where the support belt 131 is bent can be smaller, while the support plates 136 provided at the portion where the support belt 131 is not bent can be larger.

[0046] In another specific embodiment of the present application, the auxiliary support structure 13 includes a plurality of support plates 136 nested in sequence, wherein one support plate 136 has a hollow cavity. When the display screen 40 is in the folded state, another support plate 136 is embedded in the hollow cavity. When the display screen 40 is in the unfolded state, another support plate 136 extends from the hollow cavity. Of course, more support plates 136 nested in sequence can be provided according to the travel requirements, without limitation. In addition, the support plates 136 are steel structures to ensure high support strength. During the sliding process of the first support structure 11 relative to the second support structure 12, the relative movement of the plurality of support plates 136 compensates for the enlarged area of the opening 20 during the sliding process of the first support structure 11 and the second support structure 12, so as to provide stable support for the display screen 40 in all states. Among them, when the plurality of support plates 136 are in the folded state, some of the support plates 136 are completely accommodated in the previous support plate 136. When the first support structure 11 and the second support structure 12 move relative to each other, the number of support plates 136 exposed at the opening 20 increases, thereby increasing the area of the auxiliary support structure 13 at the opening 20. Of course, two adjacent support plates 136 can also be only partially embedded together. When the first support structure 11 and the second support structure 12 move relative to each other, the number of support plates 136 exposed at the opening 20 remains unchanged. By changing the extended area of each support plate 136 relative to the adjacent support plate 136, the area of the support strip 131 exposed at the opening 20 is adjusted. As long as the area of the support strip 131 exposed at the opening 20 increases when the first support structure 11 and the second support structure 12 move relative to each other, this application does not specifically limit the connection method between the multiple support plates 136.

[0047] Of course, the plurality of support plates 136 can also be partially connected by rotating in sequence, and the other parts can be connected by telescopic sleeves. The state change of the support belt 131 in the housing 10 is similar to the above, and will not be repeated.

[0048] Optionally, the driving mechanism 132 is a driving motor or a driving motor with a transmission mechanism.

[0049] The electronic device provided in the embodiment of the present application, the support belt 131 includes a plurality of support plates 136, and the plurality of support plates 136 are connected to achieve the extension or bending of the support belt 131. One end of the support belt 131 is connected to the shell 10, and the other end is connected to the driving structure. Therefore, under the action of the driving mechanism 132, the area of the support belt 131 exposed at the opening 20 changes, thereby supporting the extended area of the display screen 40, so that all areas below the display screen 40 can be supported, and there will be no weak areas.

[0050] like Figures 3 to 6As shown, in a specific embodiment of the present application, the auxiliary support structure 13 further includes a reel 133, which is fixed to the first support structure 11, and a support belt 131 is wound around the reel 133. One end of the support belt 131 is connected to the drive mechanism 132, and the other end of the support belt 131 is connected to the second support structure 12.

[0051] The reel 133 is used to pull the support belt 131 so that the support belt 131 remains flat during the movement. Figures 3 to 6 As shown, a reel 133 is disposed on a side of the first support structure 11 away from the functional module 30, and a support belt 131 is wound around the reel 133, which is disposed between the upper and lower portions of the support belt 131. Driven by a drive mechanism 132, the support belt 131 slides around the reel 133. As a result, the tension of the reel 133 ensures a more stable and uniform movement of the support belt 131, providing smoother support for the display screen 40. It should be noted that the length of the support belt 131 wound around the reel 133 is no less than the distance the first support structure 11 moves relative to the second support structure 12.

[0052] It should be noted that if Figure 1 and Figure 2 As shown, the functional module 30 corresponds to the longitudinal extension area of the second support structure 12. It is understandable that the reel 133 can also be fixed to the second support structure 12. Accordingly, one end of the support belt 131 is fixedly connected to the first support structure 11, and the other end is connected to the drive mechanism 132 by passing through the reel 133.

[0053] In the electronic device provided in the embodiment of the present application, the support belt 131 is wound on the reel 133, so that when the support belt 131 moves under the action of the driving mechanism 132, it can remain flat under the pulling of the reel 133, thereby preventing the support belt 131 from being wrinkled due to the force.

[0054] Based on the above embodiment, the reel 133 is disposed near the frame of the housing 10, the portion of the support belt 131 located on the first side of the reel 133 is disposed near the display screen 40, and the portion of the support belt 131 located on the second side of the reel 133 is disposed near the rear housing of the housing 10 opposite the display screen 40. The electronic device further includes a motherboard and / or a battery, which is disposed between the portion of the support belt 131 located on the first side of the reel 133 and the portion of the support belt 131 located on the second side of the reel 133.

[0055] like Figure 3 and Figure 5As shown, the support belt 131 is divided into two parts, upper and lower, by a reel 133. The upper part is located near the display screen 40, and the lower part is located near the rear cover of the housing 10. Specifically, the reel 133 is located near the frame of the housing 10 near the first support structure 11. One end of the support belt 131 is connected to the second support structure 12. When the first support structure 11 and the second support structure 12 move relative to each other, the distance between the reel 133 fixed to the housing 10 and the second support structure 12 changes, thereby causing the support belt 131 to expand or contract.

[0056] Among them, the motherboard and battery in the electronic device housing 10 occupy a large space. In order to avoid a significant increase in the size of the entire electronic device after the auxiliary support structure 13 is set, at least one of the motherboard and the battery is set between the upper and lower parts of the support belt 131. Compared with the layout method in which the motherboard and the battery are set above or below the support belt 131, the layout space can be fully utilized, the thickness of the electronic device can be reduced, and there will be no interference between each other.

[0057] In an optional embodiment of the present application, Figure 1 and Figure 2 As shown, the functional module 30 is arranged between the support belt 131 and the second support structure 12. Figure 4 and Figure 6 As shown, the auxiliary support structure 13 also includes a retractable first guide rail 134, the first end of the first guide rail 134 is connected to the second support structure 12, the second end of the first guide rail 134 is connected to the second end of the first support structure 11, and the first guide rail 134 is arranged on at least one side of the support belt 131.

[0058] The functional module 30 is arranged between the support belt 131 and the second support structure 12 and in the opening 20 between the second support structure 12 and the first support structure 11. Therefore, the functional module 30 is arranged in the blank area surrounded by the support belt 131, the second support structure 12 and the first support structure 11.

[0059] The first guide rail 134 comprises a multi-segment nested guide rail structure. Optionally, the first guide rail 134 comprises two nested guide rail segments. The support belt 131 can be positioned on either side of the width direction or on both sides simultaneously. The width direction of the support belt 131 is parallel to the display screen 40 and perpendicular to the direction in which the display screen 40 extends.

[0060] Because the first end of the first guide rail 134 is connected to the second support structure 12, and the second end of the second telescopic guide rail is connected to the first support structure 11, as the first support structure 11 slides relative to the second support structure 12, the first guide rail 134 expands and contracts with the changes in the support belt 131. For example, if the support belt 131 includes a plurality of support plates 136 that are sequentially telescopically nested together, as the first support structure 11 slides outward relative to the second support structure 12, the drive mechanism 132 drives the support belt 131 to extend, or the display screen 40 is deployed to drive the support belt 131 to extend, so that the multiple support plates 136 are relatively deployed and the multiple nested guide rail structures are deployed to adapt to the extended state of the support belt 131. For another example, as the first support structure 11 slides inward relative to the second support structure 12, the drive mechanism 132 drives the support belt 131 to contract, or the display screen 40 is closed to drive the support belt 131 to contract, so that the first guide rail 134 expands and contracts with the expansion and contraction of the support belt 131 to adapt to the contracted state of the support belt 131. When the support belt 131 includes a plurality of support plates 136 that are rotatably connected in sequence and the support belt 131 is capable of bending within the housing 10, the first guide rail 134 is provided on a portion of the support belt 131 that is adjacent to the display screen 40. The changing process of the support belt 131 is similar to that of the support belt 131 including a plurality of support plates 136 that are connected in a sleeve manner and will not be further described.

[0061] Specifically, both sides of the first end of the first guide rail 134 are connected to the second clamping jaws 121 on either side of the opening 20. Thus, the support belt 131 is securely connected to the right clamping jaw via the first guide rail 134, ensuring consistency with the overall clamping jaw structure and a completely flush support surface. Furthermore, both sides of the second end of the first guide rail 134 are connected to the first clamping jaws 111 on either side, securing both ends of the first guide rail 134 and allowing it to expand and contract as the display screen 40 changes state.

[0062] The electronic device provided in the embodiment of the present application uses the retractable first guide rail 134 to guide the movement of the support belt 131, thereby preventing the support belt 131 from deviating from its movement trajectory under the drive mechanism 132, and improving the smoothness and accuracy of the movement of the support belt 131.

[0063] Based on the above embodiment, the support belt 131 is fixedly connected to the first end of the first guide rail 134, and the functional module 30 is arranged between the first end of the first guide rail 134 and the second support structure 12. Figure 2 As shown, the side of the first guide rail 134 facing away from the supporting belt 131 is fixedly connected to the second supporting structure 12 via a connecting member 1341 .

[0064] Specifically, the first end of the first guide rail 134 refers to the end of the first guide rail 134 close to the functional module 30. The side of the first guide rail 134 facing away from the support belt 131 is fixedly connected to the second support structure 12 via a connector 1341. The first end of the first guide rail 134 is fixedly connected to the support belt 131, thereby fixing the support belt 131 to the second support structure 12.

[0065] In the electronic device provided in the embodiment of the present application, the support belt 131 is fixed to the first end of the first guide rail 134, and the connecting member 1341 fixedly connects the first guide rail 134 to the second support structure 12, so that the support belt 131 and the second support structure 12 are fixed without adjusting the structure of the end of the support belt 131 and the first guide rail 134. Compared with the method in which the support belt 131 and the first guide rail 134 are directly connected to the second support structure 12, the structural design of the support belt 131 and the first guide rail 134 is simpler and convenient to assemble.

[0066] like Figure 4 and Figure 6 As shown, in a specific embodiment of the present application, the auxiliary support structure 13 further includes a reel 133 and a second guide rail 135, and the second guide rail 135 is connected to the first support structure 11. The second guide rail 135 is provided on at least one side of the support belt 131. The support belt 131 is wound around the reel 133, and one end of the support belt 131 is fixed to the second support structure 12 via the first guide rail 134. At the other end of the support belt 131, only the second guide rail 135 is connected to the drive mechanism 132. The first guide rail 134 is provided near the display screen 40, and the second guide rail 135 is provided near the rear shell of the housing 10 opposite the display screen 40. The electronic device further includes a battery, which is provided between the first guide rail 134 and the second guide rail 135.

[0067] Specifically, the support belt 131 passes through the first guide rail 134, wraps around the reel 133, and passes through the second guide rail 135. As the support belt 131 moves, the second guide rail 135 simultaneously expands and contracts, allowing the support belt 131 to slide stably within the second guide rail 135. In other embodiments, the electronic device is equipped with a non-expandable internal guide rail, which is provided on the support housing 10 within the electronic device. The support belt 131 simply slides through the internal guide rail to achieve stable guided sliding.

[0068] In the electronic device provided in the embodiment of the present application, the reel 133 divides the support belt 131 into two parts, one part is arranged close to the display screen 40, and the other part is arranged close to the rear shell of the shell 10. The first guide rail 134 is arranged on the part of the support belt 131 close to the display screen 40, and the second guide rail 135 is arranged on the part of the support belt 131 close to the rear shell of the shell 10. Thus, through the cooperation of the first guide rail 134 and the second guide rail 135, stable guidance is provided for the support belt 131.

[0069] like Figure 4 and Figure 6 As shown, in an optional embodiment of the present application, the driving mechanism 132 includes a driving member 137, a gear assembly 138, and a rack 139. The driving end of the driving member 137 is connected to the input wheel of the gear assembly 138, the output wheel of the gear assembly 138 is engaged with the rack 139, and the rack 139 is connected to the support belt 131 to drive the support belt 131 to move.

[0070] It should be noted that the driving member 137 can be synchronized with the driving of the display screen 40 to expand and close, so that the electronic device has better stability, more uniform movement process and lower transmission failure rate.

[0071] Specifically, the gear assembly 138 includes a plurality of gears that mesh with each other. The display screen 40 moves slowly during the unfolding and closing process to avoid overly rapid operation that affects the service life of the display screen 40. To this end, in order to ensure that the display screen 40 and the support belt 131 operate synchronously, the output speed of the driving member 137 is adjusted by the gear assembly 138 to prevent the support belt 131 from moving too quickly and causing wrinkles or breakage. In addition, the driving member 137 is fixed in position. Under the action of the driving member 137, the rack 139 drives the support belt 131 to move. By providing the rack 139 connected to the support belt 131, it is convenient to adjust the position of the driving member 137 and the gear assembly 138 according to the space utilization in the housing 10. At the same time, the cooperation between the output wheel of the gear assembly 138 and the rack 139 can also provide guidance for the movement of the support belt 131.

[0072] Optionally, the driving member 137 determines the movement stroke according to the extreme position of the rack 139.

[0073] Optionally, the driving member 137 is a bidirectional driving motor, and the direction of the driving member 137 is determined according to the opening and closing state of the display screen 40 to cooperate with the operation of the display screen 40.

[0074] The electronic device provided in the embodiment of the present application, the driving mechanism 132 includes a driving member 137, a gear assembly 138 and a rack 139. The output speed of the driving member 137 is adjusted by the gear assembly 138, and the support belt 131 is guided and the stroke of the driving member 137 is conveniently limited by the cooperation of the gear assembly 138 and the rack 139.

[0075] In an optional embodiment, the electronic device further comprises a second drive member connected to the first support structure 11 to switch the electronic device between a folded state and an extended state. When the flexible screen is to be switched from the folded state to the extended state, the left half of the electronic device is extended to the left due to the control of the second drive member inside the electronic device, thereby achieving the expansion of the flexible screen. During this process, the drive member 137 that controls the support belt 131 rotates synchronously with the second drive member. The torque is transmitted from the output shaft of the drive member 137 to the gear at the input end of the gear reduction device. After two-stage gear reduction of the gear reduction device, it is transmitted to the rack 139. As the drive member 137 rotates, the rack 139 moves leftward along the body, driving the support belt 131 to move leftward together. At the same time, because the first end of the support belt 131 is fixedly connected to the second support structure 12, when the transmission rack 139 drives the support belt 131 and the flexible screen to move leftward, the portion of the support belt 131 located in the guide gap is subjected to a rightward pulling force, preventing the support belt 131 from getting stuck and ensuring the overall extension of the support belt 131 device to the left. Similarly, when the flexible screen is to be switched from the unfolded state to the folded state, it is sufficient to control the driving member 137 to rotate in the reverse direction.

[0076] In another optional embodiment, the driving member 137 is connected to the first support structure 11 to switch the electronic device between the folded state and the expanded state. When the driving member 137 drives the electronic device to be in the expanded state or the folded state, the support belt 131 can be driven to slide at the same time by the transmission module, eliminating the need for a separate drive, simplifying the structure of the electronic device, and reducing costs. In the embodiment of the present application, the driving member, transmission method, and operation of the electronic device that drives the device to switch between the expanded state and the closed state are known to those skilled in the art and will not be described in detail here.

[0077] like Figure 1 and Figure 2 In an optional embodiment of the present application, the functional module 30 is fixed relative to the second support structure 12, the functional module 30 has a second side facing the second support structure 12, and a fixed support plate 136 is provided between the second side of the functional module 30 and the second support structure 12.

[0078] In this embodiment, the functional module 30 does not move relative to the second support structure 12 during the transition between the expanded and closed states of the electronic device. Therefore, the fixed support plate 136 between the second side of the functional module 30 and the second support structure 12 ensures stable support of the rollable screen from the right side of the functional module 30. Specifically, the fixed support plate 136 is integrally formed with the second support structure 12. In other words, the fixed support plate 136 is actually the structure of the second support structure 12 itself.

[0079] In another optional embodiment of the present application, the housing 10 includes at least two auxiliary support structures 13, at least one of which is disposed between the functional module 30 and the first support structure 11, and at least one of which is disposed between the functional module 30 and the second support structure 12. When the first support structure 11 moves relative to the second support structure 12, the areas of the at least two auxiliary support structures 13 exposed by the opening 20 increase.

[0080] Specifically, the functional module 30 is disposed at the opening 20, and auxiliary support structures 13 are disposed on both sides of the functional module 30. When the first support structure 11 moves relative to the second support structure 12, the areas of the at least two auxiliary support structures 13 exposed by the opening 20 increase.

[0081] In a specific embodiment, the functional module 30 is movably installed at the opening 20, and its position relative to the second support structure 12 will change. When the display screen 40 of the electronic device is in the unfolded state, the functional module 30 will move to a central setting. The auxiliary support structure 13 arranged between the right side of the functional module 30 and the second support structure 12 can ensure that the right side of the functional module 30 provides stable support for the display screen 40. Specifically, unlike the above-mentioned fixed functional module 30, the auxiliary support structure 13 is directly or indirectly connected to the functional module 30 so that the auxiliary support structure 13 moves with the movement of the functional module 30. Optionally, the auxiliary support structure 13 is provided as a plurality of nested support plates 136 or a plurality of rotatably connected support plates 136, and specific reference is made to the above introduction. The specific forms of each auxiliary support structure 13 may be the same or different, and there is no specific limitation on this.

[0082] In another specific embodiment, both the left and right sides of the display screen 40 can curl, and accordingly, the auxiliary support structures 13 on the opposite sides of the functional module 30 change as the display screen 40 switches states. For example, when only one side of the display screen 40 is expanded or closed, the area of the auxiliary support structure 13 on that side increases. If both the left and right sides of the display screen 40 are expanded or closed, the area of the auxiliary support structures 13 on both sides exposed at the opening 20 increases. It can be understood that the multiple auxiliary support structures 13 provided on one side of the functional module 30 are arranged in parallel along a first direction perpendicular to the extension and contraction direction of the display screen 40.

[0083] The electronic device provided in the embodiment of the present application improves the operational flexibility of the electronic device by providing auxiliary support structures 13 on opposite sides of the functional module 30 .
