[0029] In an embodiment of the present application, when the electronic device is in the unfolded state, the first body 2 and the second body 3 are arranged side by side, and the plurality of hinge units 5 are transformed into a flat plate structure, so that the side of the electronic device facing away from the flexible screen 1 is relatively flat, and the hinge mechanism 4 can support the flexible screen 1, so that the flexible screen 1 is relatively flat, which can improve the appearance of the electronic device in the unfolded state. When the electronic device is in the folded state, the first body 2 and the second body 3 can form a preset angle, and the plurality of hinge units 5 can be transformed into an arc structure smoothly connected between the first body 2 and the second body 3, so that the first body 2 and the second body 3 can be smoothly connected through the hinge mechanism 4, which can improve the appearance of the electronic device in the folded state. In the process of switching between the unfolded state and the folded state, the electronic device in the embodiment of the present application can effectively ensure the appearance of the electronic device.

[0030] The electronic devices in the embodiments of the present application include but are not limited to: mobile phones, tablet computers, laptop computers, smart wearable devices, etc.

[0031] The flexible screen 1 in the embodiment of the present application may refer to a display screen with various forms such as bendable, foldable, curlable, etc. and good flexibility.

[0032] The first body 2 and the second body 3 in the embodiment of the present application may be the basic component structures of the electronic device, and may include: a shell, a frame, and electrical components stacked inside the frame. The electrical components may be at least one of a motherboard, a battery, a controller, a chip, a processor, and a display module.

[0033] Specifically, the flexible screen 1 can cover the display sides of the first body 2 and the second body 3 , and can cover the display module in the first body 2 and the display module in the second body 3 .

[0034] Specifically, the flexible screen 1 can be connected to the first body 2 and the second body 3 respectively. The relative state between the first body 2 and the second body 3 changes, which can drive the state of the flexible screen 1 to change. For example, when the first body 2 and the second body 3 are folded relative to each other, the flexible screen 1 can be folded; when the first body 2 and the second body 3 are unfolded relative to each other, the flexible screen 1 can be unfolded.

[0035] The hinge mechanism 4 in the embodiment of the present application can be a flexible structure, and the multiple hinge units 5 are movably connected to each other, so as to realize the flexible change of the hinge structure 4. When the relative state between the first body 2 and the second body 3 changes, the multiple hinge units 5 can be correspondingly deformed into corresponding structures. For example: when the electronic device is in a folded state, the first body 2 and the second body 3 can be at a preset angle, and the multiple hinge units 5 can be deformed into an arc structure or a wavy structure, etc., to realize a smooth connection between the first body 2 and the second body 3. When the electronic device is in an unfolded state, the first body 2 and the second body 3 can be arranged side by side, and the multiple hinge units 5 can be deformed into a flat structure.

[0036] Specifically, the angle between the first body 2 and the second body 3 can be any angle between 0°-180°. For example, when the first body 2 and the second body 3 are parallel and spaced apart, the angle between the first body 2 and the second body 3 can be 0°; when the first body 2 and the second body 3 are side by side, the angle between the first body 2 and the second body 3 can be 180°.

[0037] Specifically, the hinge unit 5 may include a first rotating rod 51 and a first sleeve 52 having an opening. For different hinge units 5, the size of the opening on the first sleeve 52 and the centerline direction of the opening may be the same or different, such as Figure 4A , 4B As shown in FIG. 4C , three different ways of setting the hinge unit 5 are shown. Other situations may refer to the settings, and the embodiments of the present application do not make specific limitations on this.

[0038] Specifically, for different hinge units 5, customizing specific openings on the first sleeve 52 can effectively ensure that each folding or opening of the first hinge part 41 and the second hinge part 42 can be completed at a predetermined angle, thereby ensuring that the hinge mechanism 4 can be deformed into a predetermined shape.

[0039] Specifically, the cross-sectional shape of the first rotating rod 51 may be circular or square. For example, the first rotating rod 51 may be a cylindrical rod or a rectangular rod, etc. The configuration may be based on actual needs, and the embodiment of the present application does not specifically limit this.

[0040] Specifically, the first sleeve 52 of one hinge unit 5 can be sleeved on the outside of the first rotating rod 51 of another hinge unit 5. The structure of the first sleeve 52 can be adapted to the structure of the first rotating rod 51. The first sleeve 52 can be a circular tube or a square tube with an opening. It can be specifically set according to actual needs, and the embodiment of the present application does not make any specific limitations on this.

[0041] Specifically, the plurality of articulated units 5 may be arranged in sequence in the same direction. Alternatively, the plurality of articulated units 5 may be divided into two parts, one part of the articulated units 5 may be arranged in sequence in one direction, and the other part of the articulated units 5 may be arranged in sequence in the opposite direction. The arrangement may be made according to actual needs, and the embodiments of the present application do not specifically limit this.

[0042] Optionally, the hinge mechanism 4 may include a first hinge mechanism 45 and a second hinge mechanism 46. The first hinge mechanism 45 may be arranged between the second hinge mechanism 46 and the flexible screen 1. The first hinge mechanism 45 and the second hinge mechanism 46 may be respectively composed of multiple hinge units 5. In the unfolded state, the first hinge mechanism 45 can be used to support the flexible screen 1, and the side of the second hinge mechanism 46 away from the flexible screen 1 is flush with the side of the first body 2 away from the flexible screen 1 and the side of the second body 3 away from the flexible screen 1.

[0043] In the embodiment of the present invention, in the unfolded state, the first hinge mechanism 45 supports the flexible screen 1, which can improve the flatness of the flexible screen 1. The side of the second hinge mechanism 46 away from the flexible screen 1 is flush with the side of the first body 2 away from the flexible screen 1 and the side of the second body 3 away from the flexible screen 1, respectively, which can further improve the flatness of the side of the electronic device away from the flexible screen 1.

[0044] Specifically, the first hinge mechanism 45 can be arranged close to the flexible screen 1, and the first hinge mechanism 45 can be an inner hinge mechanism; the second hinge mechanism 46 can be arranged away from the flexible screen 1, and the second hinge mechanism 46 can be an outer hinge mechanism. Figure 1 and 3 As shown, the electronic device is in a folded state, the angle between the first body 2 and the second body 3 is 0°, and the external hinge mechanism can form a smooth curved appearance; combined with Figure 1 and 2As shown, when the electronic device is in the unfolded state, the angle between the first body 2 and the second body 3 can be 180°, and the external hinge mechanism can form a flat plate structure arranged side by side with the first body 2 and the second body 3.

[0045] Specifically, the first hinge mechanism 45 and the second hinge mechanism 46 can be arranged at intervals. When the electronic device is in a folded state, the first hinge mechanism 45 can also be transformed into a first arc-shaped groove, and the second hinge mechanism 46 can be transformed into a second arc-shaped groove; the first arc-shaped groove can be used to store the folded flexible screen 1, and the second arc-shaped groove can be used to accommodate the first arc-shaped groove.

[0046] Specifically, the first articulated mechanism 45 and the second articulated mechanism 46 may be respectively composed of a plurality of articulated units 5 , and the first articulated mechanism 45 and the second articulated mechanism 46 may be composed of the same or different numbers of articulated units 5 .

[0047] Specifically, the size of the first hinge mechanism 45 and the second hinge mechanism 46 can be the same, or the size of the first hinge mechanism 45 can be obtained by reducing the size of the second hinge mechanism 46 according to a certain ratio, which is not specifically limited in the embodiment of the present application. Further, the size of the hinge unit 5 in the first hinge mechanism 45 and the size of the hinge unit 5 in the second hinge mechanism 46 can be the same or different, which is not specifically limited in the embodiment of the present application.

[0049] In the embodiment of the present application, among two adjacent hinge units 5, the first sleeve 52 of one hinge unit 5 can be sleeved outside the first rotating rod 51 of the other hinge unit 5 and rotatably connected to the first rotating rod 51 of the other hinge unit 5, so as to realize the rotational connection between the two adjacent hinge units 5. Since the first hinge part 41 and the second hinge part 42 both include a plurality of hinge units 5 connected in sequence, the hinge mechanism 4 is convenient to deform, so that the electronic device can switch between the unfolded state and the folded state.

[0050] like Figure 3As shown, the first hinge portion 41 and the second hinge portion 42 can be connected to form an arc structure.

[0051] Specifically, taking the first hinge portion 41 as an example, a plurality of hinge units 5 may be arranged in sequence along a first direction, and the first direction may be Figure 2 Along the first direction, the first rotating rod 51 in the previous hinge unit 5 can be embedded in the first sleeve 52 in the next hinge unit 5. Since the first sleeve 52 is provided with an opening, the rotation range and angle of the first rotating rod 51 can be limited by the opening direction and opening angle of the first sleeve 52 sleeved thereon, so that the first hinged part 41 can be directional bent, effectively ensuring that the hinge mechanism 4 can be deformed into a predetermined shape.

[0052] Specifically, the hinge unit 5 in which the first hinge part 41 is connected to the second hinge part 42 may be a first sub-hinge unit, and the hinge unit 5 in which the second hinge part 42 is connected to the first hinge part 41 may be a second sub-hinge unit.

[0053] Furthermore, the arrangement order of the hinge units 5 in the first hinge part 41 is opposite to the arrangement order of the hinge units 5 in the second hinge part 42, and the first rotating rod 51 of the first sub-hinge unit can be connected to the first rotating rod 51 of the second sub-hinge unit, or the first sleeve 52 of the first sub-hinge unit can be connected to the first sleeve 52 of the second sub-hinge unit, and the embodiment of the present application does not make specific limitations on this.

[0058] Specifically, Figure 3 As shown, in the folded state, the third hinge part 43 can be connected with the first hinge part 41 and the second hinge part 42 to form an arc structure, so that the hinge mechanism 4 can be smoothly connected between the first body 2 and the second body 3, the inner hinge mechanism 4 can accommodate the folded part of the flexible screen 1, and the outer hinge mechanism 4 can improve the appearance of the electronic device in the folded state. Figure 2 As shown, in the unfolded state, the third hinge part 43 can be respectively connected with the first hinge part 41 and the second hinge part 42 to form a flat structure, and can be parallel to the flexible screen 1. In this way, the first hinge mechanism 45 can be used to support the flexible screen 1, and the second hinge mechanism 46 can be kept flush with the first body 2 and the second body 3, which can improve the appearance of the electronic device in the unfolded state.

[0059] Specifically, the second sleeve 431 can be sleeved outside the first rotating rod 51, and the structure of the second sleeve 431 can be adapted to the structure of the first rotating rod 51. The second sleeve 431 can be a circular tube or a square tube with an opening, which can be specifically set according to actual needs, and the embodiment of the present application does not make specific limitations on this.

[0060] Specifically, the structure of the second sleeve 431 can be the same as that of the first sleeve 52, which can improve the structural aesthetics of the hinge mechanism 4 and further improve the appearance of the electronic device. The structure of the second sleeve 431 can also be different from that of the first sleeve 52, which can be set according to actual needs, and the embodiment of the present application does not specifically limit this.

[0064] Specifically, Figure 2 and Figure 3 As shown, the first hinge part 41 and the second hinge part 42 are symmetrically arranged at both ends of the third hinge part 43.
