[0021] The following combination Figures 1-6 An electronic device according to an embodiment of the present application is described.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the electronic device according to some embodiments of the present application includes: at least two frames 1; a hinge assembly 2, at least two frames 1 are rotatably connected through the hinge assembly 2 so that the electronic device has an unfolded state and a folded state, the hinge assembly 2 includes a hinge bracket 20 and a support plate 22, the support plate 22 is arranged on two opposite sides of the hinge bracket 20 and is rotatably connected to the hinge bracket 20; a display screen 3, covering the hinge assembly 2 and the at least two frames 1, a first channel 202 is provided between the hinge bracket 20 and the display screen 3, and a second channel 222 is provided between the support plate 22 and the display screen 3; a flexible circuit board 4 is passed through the first channel 202 and the second channel 222, and extends to the at least two frames 1.

[0023] In an embodiment of the present application, at least two frames 1 are rotatably connected via a hinge assembly 2, and a display screen 3 covers the hinge assembly 2 and at least two frames 1 and can move with the folding or unfolding of the electronic device to achieve the unfolding and folding of the electronic device. Among them, there is a first channel 202 between the display screen 3 and the hinge bracket 20, and a second channel 222 between the support plate 22 and the display screen 3. The flexible circuit board 4 is arranged in the first channel 202 and the second channel 222, and the two ends of the flexible circuit board 4 extend into at least two frames 1 respectively, thereby realizing signal interconnection in at least two frames 1. At the same time, the flexible circuit board 4 is arranged in the first channel 202 between the display screen 3 and the hinge bracket 20, and the second channel 222 between the support plate 22 and the display screen 3, thereby realizing the limitation of the flexible circuit board 4. When the electronic device switches between the unfolded state and the folded state, the part of the flexible circuit board 4 arranged in the first channel 202 and the second channel 222 can rotate with the movement of the electronic device, so that the flexible circuit board 4 will not form a hard contact with the support plate 22 and the hinge bracket 20, thereby avoiding affecting the service life of the flexible circuit board 4 and the hinge assembly 2 due to the folding of the electronic device, thereby ensuring the reliability of the folding and unfolding of the electronic device.

[0024] like Figure 1 As shown, according to some embodiments of the present application, optionally, the electronic device further includes: at least two fixed brackets 5, at least two fixed brackets 5 are respectively provided on at least two frames 1, and in the unfolded state, at least two fixed brackets 5 are respectively located on opposite sides of the hinge assembly 2; the flexible circuit board 4 includes a first plate body 40 and a second plate body 42, the first plate body 40 is passed through the first channel 202 and the second channel 222, the second plate body 42 is connected to both ends of the first plate body 40, and is bent from the first plate body 40 to the side away from the display screen 3; wherein, a part of the second plate body 42 is located on the side of the fixed bracket 5 facing the hinge bracket 20 and is connected to the fixed bracket 5, and the other part of the second plate body 42 extends from the side of the fixed bracket 5 away from the display screen 3 to the frame 1.

[0025] In this embodiment, the electronic device further includes at least two fixing brackets 5, which are respectively disposed within at least two frames 1 to limit the position of the flexible circuit board 4 and thereby maintain the fixed shape of the flexible circuit board 4. Specifically, the flexible circuit board 4 includes a first plate 40 and a second plate 42. The first plate 40 is disposed within the first channel 202 and the second channel 222. The second plate 42 is bent from the end of the first plate 40 in a direction away from the display screen 3. As a result, a portion of the second plate 42 is bent and disposed on the side of the fixing bracket 5 facing the hinge bracket 20. The other portion of the second plate 42 bypasses the end of the fixing bracket 5 and extends from the bottom of the fixing bracket 5 into the frame 1, thereby connecting with the circuit board within the frame 1. During the process of switching the electronic device between the unfolded state and the folded state, the first plate 40 rotates around the fixed point as the frame 1 moves, and the second plate 42 is located on the side of the fixed bracket 5 facing the hinge bracket 20 and is connected to the fixed bracket 5, so that this part of the plate can move relative to the fixed bracket 5, and the other parts are fixed relative to the frame 1. That is, through this arrangement, the movable part of the flexible circuit board 4 is reduced, and the movement trajectory becomes simple, thereby avoiding local extrusion or friction between the flexible circuit board 4 and the structural parts, greatly reducing the stress and strain on the flexible circuit board 4 during movement, and improving the fatigue life of the flexible circuit board 4. Moreover, the thickness of the fixed bracket 5 is adjustable. As the thickness of the fixed bracket 5 is reduced, the thickness of the whole machine can also be reduced, thereby achieving a lightweight design.

[0026] like Figure 2 and Figure 4 As shown, according to some embodiments of the present application, optionally, the second plate body 42 includes: a bending portion 420, which is connected to the first plate body 40 and is bent from the first plate body 40 in a direction away from the display screen 3, the bending portion 420 is connected to the fixed bracket 5, the bending portion 420 is arc-shaped, and the two ends of the bending portion 420 enclose an opening 422, and the opening 422 is set toward the hinge bracket 20; a connecting portion 424, the connecting portion 424 is connected to an end of the bending portion 420 away from the first plate body 40, and after bypassing the end of the fixed bracket 5, extends from the side of the fixed bracket 5 away from the display screen 3 into the frame 1.

[0027] In this embodiment, the second plate 42 includes a connecting portion 424 and an arc-shaped bent portion 420. The bent portion 420 is connected to the fixed bracket 5, and the connecting portion 424 is connected to the end of the bent portion 420 away from the first plate 40. It is understandable that the bent portion 420 can deform during the process of switching the electronic device between the unfolded state and the folded state. Specifically, during the process of the electronic device switching between the unfolded state and the folded state, the first plate 40 rotates around the fixed point with the movement of the frame 1, and the bent portion 420 deforms with the movement of the frame 1. One end of the connecting portion 424 is fixed to the fixed bracket 5 through the bent portion 420, and the other end is fixed to the frame 1 through the bottom of the fixed bracket 5. Therefore, the connecting portion 424 does not move, which reduces the movable area of ​​the flexible circuit board 4, thereby reducing the degree of deformation of the flexible circuit board 4, avoiding hard contact between the flexible circuit board 4 and other structural components, and ensuring the service life of the flexible circuit board 4.

[0028] In addition, the opening 422 enclosed by the two ends of the bending portion 420 is set toward the hinge bracket 20, which increases the angle between the first plate body 40 and the bending portion 420, so that the bending portion 420 transitions smoothly from the first plate body 40, thereby avoiding the occurrence of fracture between the first plate body 40 and the bending portion 420.

[0029] It is understandable that, when the electronic device switches between the unfolded state and the folded state, the first plate 40 rotates around the rotation axis of the hinge assembly 2 as the frame 1 moves.

[0030] like Figure 2 and Figure 4 As shown, according to some embodiments of the present application, optionally, the fixed bracket 5 includes: a first support portion 50, the first support portion 50 is located on one side of the hinge bracket 20 and is arranged opposite to the display screen 3, and the first support portion 50 is connected to the frame 1; a second support portion 52, one end of the second support portion 52 is connected to the end of the first support portion 50 away from the hinge bracket 20, and the other end of the second support portion 52 is supported on the bottom of the display screen 3, the bending portion 420 is located in the space surrounded by the display screen 3, the first support portion 50 and the second support portion 52, the bending portion 420 is connected to the side of the first support portion 50 facing the display screen 3, and the connecting portion 424 bypasses the end of the first support portion 50 and extends from the side of the first support portion 50 away from the display screen 3 to the inside of the frame 1.

[0031] In this embodiment, the fixed bracket 5 includes a first support portion 50 and a second support portion 52. The first support portion 50 is connected to the frame 1 and is arranged opposite the display screen 3. The second support portion 52 is connected to the end of the first support portion 50 away from the hinge bracket 20 and is supported on the bottom of the display screen 3. The bending portion 420 is located in the area between the display screen 3, the first support portion 50, and the second support portion 52, thereby limiting the bending portion 420, reducing the range of deformation of the bending portion 420, and preventing the bending portion 420 from contacting other structural components. The connecting portion 424 bypasses the end of the first support portion 50 and extends from the side of the first support portion 50 away from the display screen 3 into the frame 1, allowing a smooth transition between the connecting portion 424 and the bending portion 420.

[0032] Specifically, when the electronic device switches between the unfolded state and the folded state, the first plate 40 rotates with the movement of the frame 1, and the bent portion 420 moves closer to or further away from the second support portion 52. That is, the bent portion 420 performs a sliding-like movement relative to the second support portion 52. Specifically, when the electronic device switches from the unfolded state to the folded state, as the frame 1 folds, the distance between the second support portion 52 and the hinge bracket 20 gradually increases, and the bent portion 420 gradually moves away from the second support portion 52. When the electronic device switches from the folded state to the unfolded state, as the frame 1 moves, the distance between the second support portion 52 and the hinge bracket 20 gradually decreases, and the bent portion 420 gradually moves closer to the second support portion 52.

[0033] Optionally, in both the unfolded state and the folded state, the bent portion 420 is in an arc-shaped structure with the opening 422 facing the hinge bracket 20 .

[0034] Optionally, one end of the bending portion 420 away from the first plate body 40 is fixedly connected to the first supporting portion 50 .

[0035] Optionally, there is a gap between the fixing bracket 5 and the frame 1 , and the connecting portion 424 extends from the gap into the frame 1 .

[0036] Optionally, a portion of the connecting portion 424 is bonded between the frame 1 and a side of the fixing bracket 5 facing away from the display screen 3 .

[0037] According to some embodiments of the present application, optionally, the portion of the connecting portion 424 that passes around the end of the first supporting portion 50 is arranged in an arc shape.

[0038] In this embodiment, the portion of the connecting portion 424 that passes around the end of the first supporting portion 50 is arranged in an arc shape, so that the connecting portion 424 has a smooth transition, thereby avoiding the problem of stress concentration on the flexible circuit board 4 .

[0039] like Figure 2 and Figure 4As shown, according to some embodiments of the present application, optionally, in the unfolded state, there is a gap or they fit together between the bending portion 420 and the second support portion 52 , and in the folded state, there is a gap between the bending portion 420 and the second support portion 52 .

[0040] In this embodiment, during the process of switching the electronic device from the unfolded state to the folded state, the bent portion 420 gradually moves away from the second support portion 52; during the process of switching the electronic device from the folded state to the unfolded state, the bent portion 420 gradually approaches the second support portion 52. Therefore, in the unfolded state, a gap is set between the bent portion 420 and the second support portion 52 or the two are fitted together, so that the bent portion 420 does not rub or squeeze with the second support portion 52 during movement, thereby improving the reliability and service life of the flexible circuit board 4.

[0041] According to some embodiments of the present application, optionally, the bending portion 420 is adhesively connected to the fixing bracket 5; and / or the fixing bracket 5 and the frame 1 are an integrated structure.

[0042] In this embodiment, the bent portion 420 is adhesively connected to the fixing bracket 5, which not only allows the connection portion 424 of the bent portion 420 to have a certain degree of deformation ability, but also ensures that the bent portion 420 is fixed, so that the bent portion 420 maintains a fixed shape, thereby preventing the electronic device from malfunctioning due to the position movement of the bent portion 420. When the fixing bracket 5 and the frame 1 are an integrated structure, the difficulty of processing and assembly is reduced.

[0043] According to some embodiments of the present application, optionally, the electronic device further includes: a circuit board bracket, which is arranged in the frame 1, and a third channel is provided between the circuit board bracket and the display screen 3, and both ends of the flexible circuit board 4 are respectively passed through the third channel and fixed to the circuit board bracket.

[0044] In this embodiment, the electronic device further includes a circuit board holder, which is mounted on the frame 1. The mainboard within the frame 1 is mounted on the circuit board holder. A third channel is provided between the circuit board holder and the display screen 3. The end of the flexible circuit board 4 extending into the frame 1 is positioned within the third channel, thereby limiting the position of the flexible circuit board 4 within the frame 1. This allows the flexible circuit board 4 to fold or unfold with the display screen 3, reducing hard contact, compression, or friction between the flexible circuit board 4 and other structural components. Furthermore, the end of the flexible circuit board 4 located within the frame 1 is fixed to the circuit board holder, thereby connecting the flexible circuit board 4 to the mainboard.

[0045] like Figure 6As shown, according to some embodiments of the present application, optionally, a first avoidance groove 204 is provided on the side of the hinge bracket 20 facing the display screen 3, and a second avoidance groove 224 is provided on the side of the support plate 22 facing the display screen 3. The display screen 3 and the first avoidance groove 204 together enclose a first channel 202, and the display screen 3 and the second avoidance groove 224 together enclose a second channel 222.

[0046] In this embodiment, a first escape groove 204 is provided on the side of the hinge bracket 20 facing the display screen 3. The first escape groove 204 and the display screen 3 together form a first channel 202 for accommodating the flexible circuit board 4. A second escape groove 224 is provided on the side of the support plate 22 facing the display screen 3. The second escape groove 224 and the display screen 3 together form a second channel 222 for accommodating the flexible circuit board 4. Slots are formed in the hinge bracket 20 and support plate 22, allowing the flexible circuit board 4 to be positioned within the pre-designed first channel 202 and second channel 222 between the display screen 3, the hinge bracket 20, and the support plate 22. The flexible circuit board 4 is positioned in the gap between the frame 1 and the display screen 3, restricting it to sliding or rotating within the pre-designed space between the display screen 3, the hinge assembly 2, and the frame 1. This effectively prevents interference between the flexible circuit board 4 and the support plate 22, the hinge back cover, and the frame 1, reducing the overall thickness of the device, achieving a lightweight and thin product design, and extending the life of the folded terminal.

[0047] It can be understood that the display screen 3 is a flexible screen.

[0048] Optionally, the electronic device further includes a secondary screen, which is provided on at least one side of the frame 1 facing away from the display screen 3 .

[0049] According to some embodiments of the present application, optionally, along the rotation axis direction of the support plate 22, the difference between the width of the first channel 202 and the width of the flexible circuit board 4 is greater than or equal to 1 mm and less than or equal to 5 mm, and the difference between the width of the second channel 222 and the width of the flexible circuit board 4 is greater than or equal to 1 mm and less than or equal to 5 mm.

[0050] In this embodiment, the width of the first channel 202 along the support plate 22 is 1 mm to 5 mm longer than the width of the flexible circuit board 4 disposed therein. Correspondingly, the width of the second channel 222 along the rotation axis of the support plate 22 is 1 mm to 5 mm longer than the width of the flexible circuit board 4 disposed therein. On the one hand, this facilitates the installation of the flexible circuit board 4, and on the other hand, it can also prevent the edge of the flexible circuit board 4 from making hard contact with the hinge bracket 20 or the support plate 22.

[0051] Specifically, the difference between the width of the first channel 202 and the width of the flexible circuit board 4 is equal to any value among 1mm, 2mm, 3mm, 4mm, and 5mm; the difference between the width of the second channel 222 and the width of the flexible circuit board 4 is equal to any value among 1mm, 2mm, 3mm, 4mm, and 5mm.

[0052] According to some embodiments of the present application, optionally, the flexible circuit board 4 is movably connected to the first channel 202 and the second channel 222 respectively.

[0053] In this embodiment, the flexible circuit board 4 is movably connected to the first channel 202 and the second channel 222, respectively, so that the flexible circuit board 4 can bend with the display screen 3 and slide freely, reducing the possibility of hard contact between the flexible circuit board 4 and other structural parts.

[0054] In a specific application, the hinge keel (such as the hinge bracket 20) and the hinge door panel (such as the support plate 22) are partially grooved at the layout position of the hinge FPC (such as the flexible circuit board 4, used to realize signal interconnection between at least two frames 1), and the hinge FPC is arranged in a pre-designed channel between the main screen (such as the display screen 3) and the hinge keel and the hinge door panel. The hinge FPC is partially arranged in the gap space between the middle frame (such as the frame 1) and the main screen, so that the hinge FPC can only slide or rotate in the pre-designed space between the main screen and the hinge assembly 2 and the middle frame. This can effectively avoid movement interference between the hinge FPC and the hinge door panel, the hinge back cover and the middle frame, alleviate the problem of force concentration on the hinge FPC during bending, and improve the fatigue resistance of the hinge FPC. This structure changes the movement form of the hinge FPC, which is conducive to reducing the thickness of the whole machine, realizing a lightweight design of the product, and at the same time improving the folding life of the terminal.

[0055] Specifically, grooves about 0.2 mm deep (such as the first avoidance groove 204 and the second avoidance groove 224) are opened at the hinge door panel and the position where the hinge keel passes the shaft FPC. The groove width depends on the width of the shaft FPC and is usually about 1 mm wider than the width of the shaft FPC. These grooves and the main screen form a reserved channel (such as the first channel 202 and the second channel 222) that allows the shaft FPC to bend with the screen and slide freely. This channel allows the shaft FPC to slide freely inside it. The shaft FPC is then connected to the middle frame through a fixing bracket 5. The fixing bracket 5 plays the role of keeping the shape of the shaft FPC fixed. Since the shaft FPC and the middle frame do not produce relative movement during the movement of the shaft FPC, only stable and reliable fixation is required.

[0056] The motion trajectory of the rotating shaft FPC can be roughly divided into two intervals. In the first interval (such as Figure 5 As shown in the A section, the shaft FPC rotates around the fixed point as the main screen is folded and unfolded. In the second section (as shown in the Figure 5 In the B interval shown in the figure, the shaft FPC only slides relatively; therefore, compared with the existing design scheme, the movement trajectory of the FPC becomes simpler, and local interference between the shaft FPC and the structural parts can be avoided, which greatly reduces the stress and strain on the shaft FPC during movement and improves the fatigue life of the FPC. In addition, the thickness of the fixing bracket 5 is adjustable. As the fixing bracket 5 is thinner, the thickness of the entire machine can also be reduced, thereby realizing a lightweight design of the product.

[0057] For the sake of convenience, the hinge FPC in this application is fixed to the main and auxiliary bodies (for example, two frames 1) through the middle frame, and then connected to the main and auxiliary boards. However, the fixation and interconnection of the hinge FPC and the main and auxiliary bodies are not limited to the method proposed in this application. The hinge FPC can also be directly fixed through structures such as main and auxiliary board brackets (for example, circuit board brackets) to achieve the connection between the hinge FPC and the main and auxiliary boards.
