Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, and specifically relates to an electronic device. Background Technology

[0002] With the rapid development of smart electronic device technology, people have increasingly higher demands for electronic devices. They want electronic devices not only to have sufficiently large displays for convenient office work, but also to be foldable for easy portability. Therefore, flexible screen electronic devices have emerged, such as foldable screen phones.

[0003] The flexible screen electronic device includes a device body and a flexible screen, with the flexible screen connected to the top of the device body. The device body includes a first frame, a second frame, and a hinge connecting the first frame and the second frame. The hinge drives the first frame and the second frame to fold against each other, thereby causing the flexible screen to fold.

[0004] However, when flexible screen electronic devices are folded, an arching phenomenon occurs, which affects the display effect at the fold and may even cause damage to the fold. Summary of the Invention

[0005] This application aims to provide an electronic device to solve, or at least partially solve, the problem in the prior art where, when a flexible screen electronic device is folded, the flexible screen exhibits an anti-arching phenomenon, thereby affecting the display effect at the folded part of the flexible screen and even causing damage to the folded part of the flexible screen.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows:

[0007] This application provides an electronic device, including: a device body comprising two frames and a hinge assembly connecting the two frames, the hinge assembly enabling the electronic device to switch between a folded state and an unfolded state; the hinge assembly having a hinge arm assembly and a base, one end of the hinge arm assembly being rotatably connected to the base, and the other end of the hinge arm assembly being connected to the frames; a flexible screen connected to the device body, with a first end and a second end of the flexible screen respectively connected to opposite ends of the two frames; and a support assembly disposed between the hinge arm assembly and the base, wherein when the electronic device is in the unfolded state, the support assembly is at least partially connected to the frames, causing the frames to extend in a direction away from the hinge assembly.

[0008] This application provides an electronic device comprising: a device body including two frames and a hinge assembly connecting the two frames, the hinge assembly enabling the electronic device to switch between a folded state and an unfolded state; the hinge assembly having a hinge arm assembly and a base, one end of the hinge arm assembly being rotatably connected to the base, and the other end of the hinge arm assembly being connected to the frames; a flexible screen connected to the device body, with a first end and a second end of the flexible screen respectively connected to opposite ends of the two frames; and a support assembly disposed between the hinge arm assembly and the base, wherein when the electronic device is in the unfolded state, the support assembly is at least partially connected to the frames, causing the frames to extend in a direction away from the hinge assembly. In this embodiment, a support component is disposed between the hinge arm assembly and the base. When the electronic device is in the unfolded state, the support component is at least partially connected to the frame, thereby causing the frame to extend away from the hinge assembly, moving the frame and the hinge assembly away from each other, and keeping the flexible screen in a taut state, thereby preventing the flexible screen from arching.

[0033] The following will be combined with the appendix Figures 1 to 12 The electronic devices provided in this application will be described in detail through specific embodiments and application scenarios.

[0034] like Figure 1 As shown in the prior art, when a flexible screen electronic device is folded, an arching phenomenon occurs, which affects the display effect at the folded part of the flexible screen and may even cause damage to the folded part of the flexible screen.

[0035] like Figures 2 to 12 As shown in the figure, this application provides an electronic device, which includes: a device body, the device body including two frames 10 and a hinge assembly 20 connected between the two frames 10, the hinge assembly 20 enabling the electronic device to switch between a folded state and an unfolded state; the hinge assembly 20 having a hinge arm assembly and a base 23, one end of the hinge arm assembly being rotatably connected to the base 23, and the other end of the hinge arm assembly being connected to the frame 10; a flexible screen 30, the flexible screen 30 being connected to the device body, and the first end and the second end of the flexible screen 30 being respectively connected to the two opposite ends of the two frames 10; and a support assembly 40, the support assembly 40 being disposed between the hinge arm assembly and the base 23, wherein when the electronic device is in the unfolded state, the support assembly 40 is at least partially connected to the frame 10, so that the frame 10 extends in a direction away from the hinge assembly 20.

[0036] The electronic device in this application embodiment can be a flexible screen mobile phone, i.e., a foldable mobile phone, a flexible screen tablet computer, i.e., a foldable tablet computer, or any other flexible screen electronic device. This application does not impose excessive restrictions on the specific type of flexible screen electronic device. The following description will use a foldable mobile phone as an example of a flexible screen electronic device.

[0037] like Figures 2 to 12 As shown, the electronic device provided in this application embodiment is a flexible screen electronic device. The flexible screen electronic device includes a device body, which includes a hinge assembly 20 and two frames 10. One frame 10 is connected to one side of the hinge assembly 20, and the other frame 10 is connected to the other side of the hinge assembly 20.

[0038] The hinge assembly 20 in this embodiment can switch the flexible screen electronic device between an unfolded state and a folded state. When the flexible screen electronic device is in the unfolded state, it has a large display screen, making it easy for users to operate, for example, for office work. When the flexible screen electronic device is in the folded state, it is smaller in size and easier to carry.

[0039] The hinge assembly 20 in this embodiment includes a hinge arm assembly and a base 23. The hinge arm assembly is disposed between the base 23 and the frame 10. One end of the hinge arm assembly is rotatably connected to the base 23, allowing it to rotate around the base 23. The other end of the hinge arm assembly is connected to the frame 10, and its rotation around the base 23 causes the frame 10 to rotate around the base 23.

[0040] The flexible screen 30 in this embodiment is also referred to as a flexible OLED display. The flexible screen 30 features bendability, good flexibility, and low power consumption. The flexible screen 30 is connected to the device body and includes a first end and a second end disposed opposite each other. One end of the flexible screen 30 is connected to the end of a frame 10 away from the hinge assembly 20, and the other end of the flexible screen 30 is connected to the end of another frame 10 away from the hinge assembly 20, thereby allowing the flexible screen 30 to cover the upper surface of the device body. Furthermore, the flexible screen 30 is electrically connected to the device body.

[0041] The electronic device in this embodiment further includes a support assembly 40, which is disposed between the hinge arm assembly and the base 23. Figures 5 to 6 as well as Figures 9 to 10 As shown, when the electronic device is in the unfolded state, the support component 40 is at least partially connected to the frame 10, thereby causing the frame 10 to extend in a direction away from the hinge component 20, so that the frame 10 and the hinge component 20 are moved away from each other, and the flexible screen 30 is in a taut state, thereby preventing the flexible screen 30 from arching.

[0042] like Figures 7 to 8 as well as Figures 11 to 12 As shown, when the electronic device is in a folded state, the frame 10 and the hinge assembly 20 are separated, and the support assembly 40 no longer provides force to the frame 10. Therefore, the folding effect of the electronic device is not affected.

[0043] It should be noted that, in this embodiment, the hinge arm assembly includes two components: a first hinge arm assembly and a second hinge arm assembly. The first hinge arm assembly is rotatably connected to one side of the base 23, and the second hinge arm assembly is rotatably connected to the other side of the base 23. The two frames 20 are the first frame and the second frame, respectively. The first frame is connected to the side of the first hinge arm assembly away from the base 23, and the second frame is connected to the other side of the second hinge arm assembly away from the base 23.

[0044] The support assembly 40 may include at least two components. The at least two support assemblies 40 may include at least one first support assembly and at least one second support assembly. The at least one first support assembly is disposed between the first hinge arm assembly and the base 23, and the at least one second support assembly is disposed between the second hinge arm assembly and the base 23.

[0045] When the electronic device is in the unfolded state, the first support component is at least partially connected to the first frame, causing the first frame to extend in a direction away from the hinge component 20. Simultaneously, the second support component is at least partially connected to the second frame, causing the second frame to extend in a direction away from the hinge component 20. Both sides of the flexible screen 30 are in a taut state, thereby better preventing the flexible screen 30 from arching.

[0046] Of course, in this embodiment, the specific number of support components 40 is not limited. In actual use, technicians can set a corresponding number of support components 40 between the first hinge arm assembly and the base 23, and between the first hinge arm assembly and the base 23, as needed.

[0047] This application provides an electronic device comprising: a device body including two frames 10 and a hinge assembly 20 connected between the two frames 10, the hinge assembly 20 enabling the electronic device to switch between a folded state and an unfolded state; the hinge assembly 20 having a hinge arm assembly and a base 23, one end of the hinge arm assembly being rotatably connected to the base 23, and the other end of the hinge arm assembly being connected to the frame 10; a flexible screen 30 connected to the device body, the first end and the second end of the flexible screen 30 being respectively connected to the two opposite ends of the two frames 10; and a support assembly 40 disposed between the hinge arm assembly and the base 23, wherein when the electronic device is in the unfolded state, the support assembly 40 is at least partially connected to the frame 10, so that the frame 10 extends in a direction away from the hinge assembly 20. In this embodiment, the support component 40 is disposed between the hinge arm assembly and the base 23. When the electronic device is in the unfolded state, the support component 40 is at least partially connected to the frame 10, thereby causing the frame 10 to extend in a direction away from the hinge assembly 20, so that the frame 10 and the hinge assembly 20 are moved away from each other, and the flexible screen 30 is in a taut state, thereby avoiding the arching phenomenon of the flexible screen 30.

[0048] Additionally, in some alternative embodiments, such as Figures 5 to 12 As shown, the hinge arm assembly includes a hinge arm body 21 and a hinge bracket 22. The hinge arm body 21 is rotatably connected to the base 23, the hinge bracket 22 is connected to the hinge arm body 21, the frame 10 is connected to the hinge bracket 22, and a support assembly 40 is disposed between the hinge arm body 21 and the hinge bracket 22. When the electronic device is in the unfolded state, the support assembly 40 is at least partially connected to the hinge bracket 22 so that the hinge bracket 22 extends in a direction away from the hinge arm body.

[0049] In the embodiments of this application, such as Figures 5 to 12 As shown, the hinge arm assembly includes a hinge arm body 21 and a hinge bracket 22. The hinge arm body 21 is rotatably connected to one side of the base 23. The hinge bracket 22 is connected to the side of the hinge arm body 21 away from the base 23. The frame 10 is connected to the side of the hinge bracket 22 away from the hinge arm body 21.

[0050] It should be noted that the hinge arm body 21 in this embodiment of the invention includes two parts: a first hinge arm body and a second hinge arm body. The first hinge arm body is rotatably connected to one side of the base 23, and the second hinge arm body is rotatably connected to the other side of the base 23. The hinge bracket 22 also includes two parts: one hinge bracket 22 is connected to the side of the first hinge arm body away from the base 23, and the other hinge bracket 22 is connected to the side of the second hinge arm body away from the base 23.

[0051] Of course, the frame 10 also includes a first frame and a second frame. The first frame is detachably connected to a hinge bracket 22 on the side away from the first hinge arm body by bolts, and the second frame is detachably connected to another hinge bracket 22 on the side away from the second hinge arm body by bolts.

[0052] like Figures 5 to 12 As shown, the support assembly 40 is positioned between the hinge arm body 21 and the hinge bracket 22. When the electronic device is in the deployed state, the support assembly 40 is at least partially connected to the hinge bracket 22, causing the hinge bracket 22 to extend away from the hinge arm body 21. This moves the hinge bracket 22 and the hinge arm body 21 away from each other, thereby causing the frame 10 and the hinge arm body 21 to move away from each other, keeping the flexible screen 30 in a taut state and preventing the flexible screen 30 from arching.

[0053] like Figures 7 to 8 as well as Figures 11 to 12 As shown, when the electronic device is in a folded state, the hinge bracket 22 and the hinge arm body 21 are separated, and the support assembly 40 no longer provides force to the hinge bracket 22. Therefore, the folding effect of the electronic device is not affected.

[0054] Additionally, in some alternative embodiments, the support component 40 includes an elastic component 41, which is movably connected to the hinge bracket 22 and reciprocates on the hinge bracket 22; wherein, when the electronic device is in the unfolded state, the hinge bracket 22 moves toward the hinge arm body 21, and the elastic component 41 abuts against the hinge arm body 21 and the hinge bracket 22, so that the hinge bracket 22 extends toward the direction away from the hinge arm body 21.

[0055] In this embodiment of the application, the support component 40 can be configured as an elastic component 41, and the elastic component 41 can be movably connected to the hinge bracket 22, and the elastic component 41 can reciprocate on the hinge bracket 22.

[0056] When the electronic device is in the unfolded state, the hinge bracket 22 moves toward the hinge arm body 21, causing the elastic component 41 to abut against the hinge arm body 21 and the hinge bracket 22, and causing the hinge bracket 22 to extend away from the hinge arm body 21. This causes the frame 10 and the hinge arm body 21 to move away, keeping the flexible screen 30 in a taut state, thereby preventing the flexible screen 30 from arching.

[0057] like Figures 7 to 8 as well as Figures 11 to 12 As shown, when the electronic device is in a folded state, the hinge bracket 22 and the hinge body 21 are separated, and the elastic component 41 no longer provides elastic force to the hinge bracket 22. Therefore, the folding effect of the electronic device is not affected.

[0058] It should be noted that the elastic component 41 in this embodiment can be a spring or other elastic structural member. In this embodiment, no specific restrictions are placed on the specific structure of the elastic component 41; any elastic structural member is acceptable. In practical use, those skilled in the art can configure the specific structure of the elastic component 41 as needed.

[0059] Additionally, in some alternative embodiments, such as Figures 5 to 8 As shown, the support assembly 40 includes a connecting rod and a spring 413. A first through hole is provided on the hinge bracket 22, through which the connecting rod passes and can slide. The connecting rod stops at the hinge bracket 22. The spring 413 is sleeved on the connecting rod, with one end abutting against the hinge bracket 22 and the other end abutting against the stop of the connecting rod, the stop being close to the hinge arm body 21. When the electronic device is in the unfolded state, one end of the connecting rod abuts against the hinge arm body 21, and the other end abuts against the hinge bracket 22.

[0060] In the embodiments of this application, such as Figures 5 to 8 As shown, the support assembly 40 includes a connecting rod and a spring 413. A first through hole is provided on the hinge bracket 22, through which the connecting rod passes and can slide along the first through hole. Stops are provided at both ends of the connecting rod to stop it in the hinge bracket 22 and prevent it from slipping out of the first through hole.

[0061] The spring 413 is sleeved on the connecting rod, with one end of the spring 413 abutting against the hinge bracket 22 and the other end abutting against the stop of the connecting rod, which is the stop of the connecting rod near the hinge arm body 21. When the electronic device is in the unfolded state, one end of the connecting rod can abut against the hinge arm body 21, and the other end of the connecting rod can abut against the hinge bracket 22.

[0062] The above structure, such as Figures 5 to 6 As shown, when the electronic device is in the unfolded state, the spring 413 can provide an elastic force to the hinge bracket 22 away from the hinge arm body 21, causing the hinge bracket 22 to extend in a direction away from the hinge arm body 21. The hinge bracket 22 can drive the frame 10 to extend in a direction away from the hinge arm body 21, and the flexible screen 30 is in a taut state, thereby avoiding the arching phenomenon of the flexible screen 30.

[0063] like Figures 7 to 8 As shown, when the electronic device is in a folded state, the hinge bracket 22 and the hinge arm body 21 are separated, and the connecting rod no longer abuts against the hinge arm body 21 and / or the hinge bracket 22. Therefore, the spring 413 will not provide an elastic force to the hinge bracket 22 away from the hinge arm body 21, thus not affecting the folding effect of the electronic device.

[0064] In some alternative embodiments, the connecting rod includes a screw 411 and a nut 412, wherein the screw 411 passes through the first through hole and can slide along the first through hole, and the nut 412 is connected to the end of the screw 411 near the hinge arm body 21; a spring 413 is sleeved on the screw 411, and one end of the spring 413 abuts against the hinge bracket 22, and the other end of the spring 413 abuts against the nut 412; when the electronic device is in the unfolded state, one end of the screw 411 abuts against the hinge arm body 21, and the other end of the screw 411 abuts against the hinge bracket 22.

[0065] In the embodiments of this application, such as Figures 5 to 8 As shown, the connecting rod includes a screw 411 and a nut 412. The screw 411 passes through a first through hole provided on the hinge bracket 22, and the screw 411 can slide along the first through hole. The nut 412 is connected to the end of the screw 411 near the hinge arm body 21.

[0066] In this design, spring 413 is fitted onto the screw shank of screw 411, with one end of spring 413 abutting against hinge bracket 22 and the other end abutting against nut 412. When the electronic device is in the unfolded state, one end of screw 411 can abut against hinge arm body 21, and the other end of screw 411 can abut against hinge bracket 22. Thus, spring 413 provides an elastic force to hinge bracket 22 away from hinge arm body 21, causing hinge bracket 22 to extend in a direction away from hinge arm body 21. This allows hinge bracket 22 to drive frame 10 to extend in a direction away from hinge arm body 21, keeping flexible screen 30 taut and preventing anti-arching of flexible screen 30.

[0067] like Figures 7 to 8 As shown, when the electronic device is in a folded state, the hinge bracket 22 and the hinge arm body 21 are separated, and the screw 411 no longer abuts against the hinge arm body 21 and / or the hinge bracket 22. Therefore, the spring 413 no longer provides an elastic force to the hinge bracket 22 away from the hinge arm body 21. This does not affect the normal folding of the electronic device.

[0068] It should be noted that, in this embodiment of the application, as an optional implementation, one end of the spring 413 may abut against the hinge bracket 22, and the other end of the spring 413 may abut against the head of the screw 411. This embodiment of the application does not impose excessive limitations on this; in actual use, those skilled in the art can configure it as needed.

[0069] Additionally, in some alternative embodiments, such as Figures 9 to 12 As shown, the support assembly 40 includes a magnetic assembly 42, wherein the magnetic assembly 42 includes at least two magnetic elements, wherein at least one magnetic element is disposed on the hinge arm body 21, and at least another magnetic element is disposed on the hinge bracket 22, and the magnetic poles of the at least two magnetic elements that are close to each other are the same magnetic poles; when the electronic device is in the unfolded state, the at least two magnetic elements repel each other, so that the hinge bracket 22 extends in a direction away from the hinge arm body 21.

[0070] In the embodiments of this application, such as Figures 9 to 12 As shown, the support assembly 40 can be configured as a magnetic assembly 42, and the magnetic assembly 42 includes at least two magnetic elements. At least one magnetic element is disposed on the hinge arm body 21; specifically, at least one magnetic element can be disposed on the side of the hinge arm body 21 near the hinge bracket 22. At least one additional magnetic element is disposed on the hinge bracket 22; specifically, at least another magnetic element can be disposed on the side of the hinge bracket 22 near the hinge arm body 21. The magnetic poles of the at least two magnetic elements that are close to each other are configured to have the same magnetic pole.

[0071] When the electronic device is in the unfolded state, since the magnetic poles of at least two magnetic components that are close to each other are the same, the at least two magnetic components repel each other. This allows a magnetic force to be provided to the hinge bracket 22 away from the hinge arm body 21, causing the hinge bracket 22 to extend in a direction away from the hinge arm body 21. This, in turn, causes the frame 10 to extend in a direction away from the hinge arm body 21, keeping the flexible screen 30 in a taut state and preventing the flexible screen 30 from arching.

[0072] When the electronic device is in a folded state, the hinge bracket 22 and the hinge arm body 21 are separated. At least two magnetic components are far apart, which reduces the magnetic force between the magnetic components, making the magnetic force insufficient to push the hinge bracket 22 to extend away from the hinge arm body 21.

[0073] The magnetic component can be a magnet or other magnetic structural component. In this embodiment, no specific restrictions are placed on the type of magnetic component.

[0074] Additionally, in some alternative embodiments, such as Figures 9 to 12 As shown, the magnetic component 42 includes multiple sets, each set of magnetic components 42 including a first magnetic element 421 and a second magnetic element 422, wherein the first magnetic element 421 is disposed on the hinge arm body 21, and the second magnetic element 422 is disposed on the hinge bracket 22. The first magnetic element 421 and the second magnetic element 422 are at least partially opposite to each other; and the magnetic poles of the first magnetic element 421 near the second magnetic element 422 and the magnetic poles of the second magnetic element 422 near the first magnetic element 421 are the same magnetic poles.

[0075] like Figures 9 to 12 As shown, the magnetic components 42 include multiple sets, which are spaced apart. The multiple sets of magnetic components 42 provide a magnetic force to the hinge bracket 22 away from the hinge arm body 21, thereby providing a stronger magnetic force to the hinge bracket 22, enabling the hinge bracket 22 to quickly extend in a direction away from the hinge arm body 21.

[0076] Each set of magnetic components 42 includes a first magnetic element 421 and a second magnetic element 422. The first magnetic element 421 is disposed on the side of the hinge arm body 21 near the hinge bracket 22, and the second magnetic element 422 is disposed on the side of the hinge bracket 22 near the hinge arm body 21.

[0077] Furthermore, in this embodiment, the first magnetic element 421 and the second magnetic element 422 are at least partially opposite to each other, and the magnetic poles of the first magnetic element 421 near the second magnetic element 422 and the magnetic poles of the second magnetic element 422 near the first magnetic element 421 are set to be the same. This makes the magnetic force between the first magnetic element 421 and the second magnetic element 422 stronger, thereby providing a stronger magnetic force to the hinge bracket 22, allowing the hinge bracket 22 to extend in a direction away from the hinge arm body 21.

[0078] In some alternative embodiments, a first groove is provided on the side of the hinge arm body 21 near the hinge bracket 22, and a first magnetic element 421 is embedded in the first groove; a second groove is provided on the side of the hinge bracket 22 near the hinge arm body 21, and a second magnetic element 422 is embedded in the second groove.

[0079] In this embodiment, a first groove can be provided on the side of the hinge arm body 21 near the hinge bracket 22, and the first magnetic element 421 can be embedded in the first groove to fix the first magnetic element 421. A second groove can be provided on the side of the hinge bracket 22 near the hinge arm body 21, and the second magnetic element 422 can be embedded in the second groove to fix the second magnetic element 422.

[0080] In this configuration, along the axis perpendicular to the hinge arm body 21, the first groove and the second groove can be at least partially arranged opposite each other, so that the first magnetic element 421 embedded in the first groove and the second magnetic element 422 embedded in the second groove are at least partially arranged opposite each other.

[0081] In some alternative embodiments, the hinge bracket 22 is slidably connected to the hinge arm body 21 along a direction perpendicular to the axis of the base 23, and the frame 10 is fixedly connected to the hinge bracket 22.

[0082] like Figures 5 to 12 As shown, along a direction perpendicular to the axis of the base 23, the hinge arm body 21 is rotatably connected to the base 23, the hinge bracket 22 is slidably connected to the hinge arm body 21, and the frame 10 is fixedly connected to the hinge bracket 22. The hinge arm body 21 drives the frame 10 to rotate around the base 23, and the hinge bracket 22 drives the frame 10 to slide from a direction close to the base 23 towards a direction away from the base 23, or vice versa. This allows the electronic device to switch between an unfolded state and a folded state.

[0083] Additionally, in some alternative embodiments, such as Figure 4 As shown, the support assembly 40 includes multiple components, wherein the multiple support assemblies 40 are spaced apart along the axial direction of the base 23.

[0084] In the embodiments of this application, such as Figure 4 As shown, the support components 40 include multiple components. These multiple support components 40 are spaced apart along the axial direction of the base 23. The multiple support components 40 provide a force to the frame 10 away from the hinge component 20, causing the frame 10 to extend in a direction away from the hinge component 20. The arrangement of multiple support components 40 makes the force on the frame 10 more even, thus ensuring that different positions of the flexible screen 30 can be in a taut state.

[0085] It should be noted that the multiple support components 40 in this embodiment can be divided into two groups. One group of support components 40 can be disposed between the first hinge arm assembly and the base 23, so as to provide a force away from the hinge assembly 20 to the first frame, causing the first frame to extend in a direction away from the hinge assembly 20. The other group of support components 40 can be disposed between the second hinge arm assembly and the base 23, so as to provide a force away from the hinge assembly 20 to the second frame, causing the second frame to extend in a direction away from the hinge assembly 20.

[0086] For example, the number of support components 40 can be set to 10, divided into two groups of 5 support components 40 each. Along the axial direction of the base 23, 5 support components 50 are spaced apart between the first hinge arm assembly and the base 23. The other 5 support components 40 are positioned between the second hinge arm assembly and the base 23. This ensures that the force acting on the first frame away from the hinge assembly 20 and the force acting on the second frame away from the hinge assembly 20 are the same or similar.

[0087] This application provides an electronic device comprising: a device body including two frames and a hinge assembly connecting the two frames, the hinge assembly enabling the electronic device to switch between a folded state and an unfolded state; the hinge assembly having a hinge arm assembly and a base, one end of the hinge arm assembly being rotatably connected to the base, and the other end of the hinge arm assembly being connected to the frames; a flexible screen connected to the device body, with a first end and a second end of the flexible screen respectively connected to opposite ends of the two frames; and a support assembly disposed between the hinge arm assembly and the base, wherein when the electronic device is in the unfolded state, the support assembly is at least partially connected to the frames, causing the frames to extend in a direction away from the hinge assembly. In this embodiment, a support component is disposed between the hinge arm assembly and the base. When the electronic device is in the unfolded state, the support component is at least partially connected to the frame, thereby causing the frame to extend away from the hinge assembly, moving the frame and the hinge assembly away from each other, and keeping the flexible screen in a taut state, thereby preventing the flexible screen from arching.
