[0042] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) are relative rather than absolute when describing the structure and movement of the various components, and are not intended to limit the direction of the product during actual use.

[0043] Furthermore, in the description of this application, ordinal numbers, such as "first" and "second," are used only to distinguish related objects and should not be construed as indicating or implying the relative importance or order between related objects.

[0044] like Figures 1 to 4As shown, in one or more embodiments, this disclosure provides a dual-screen electronic device, including a host 100, a bracket 200, an adjustment component 300, and a secondary screen 400; the bracket 200 is detachably disposed on the host 100; the adjustment component 300 includes a flip shaft 310 and a rotating component 320, the rotating component 320 being movably connected to the bracket 200 via the flip shaft 310, and the rotation axis of the rotating component 320 being perpendicular to the axis of the flip shaft 310; the secondary screen 400 is connected to the rotating component 320; when the flip shaft 310 rotates, it drives the secondary screen 400 to flip relative to the bracket 200; when the rotating component 320 rotates, it drives the secondary screen 400 to rotate relative to the flip shaft 310.

[0045] In this embodiment, the stand 200 is detachably mounted on the host 100, and the secondary screen 400 is connected to the stand 200 via the adjustment component 300. When the stand 200 is mounted on the host 100, the secondary screen 400 and the host 100 are integrated. When the stand 200 is detached from the host 100, the secondary screen 400 is separated from the host 100, and then the secondary screen 400 can be placed on a desktop or other location required by the user via the stand 200. This embodiment does not limit the specific working mode of the secondary screen 400 after it is separated from the host 100. For example, after the secondary screen 400 is detached from the host 100, it can maintain a communication connection with the host 100, enabling the secondary screen 400 and the host 100 to display simultaneously on different screens; or the secondary screen 400 and the host 100 can display different images, achieving different display on different screens.

[0046] The adjustment component 300 includes a flip shaft 310 and a rotating component 320. The rotating component 320 is connected to the bracket 200 via the flip shaft 310. The flip shaft 310 is horizontally oriented, and the rotating component 320 flips around the flip shaft 310, allowing it to rotate relative to the bracket 200. Simultaneously, the rotating component 320 is rotatable relative to the flip shaft 310. The secondary screen 400 is connected to the rotating component 320. When the flip shaft 310 rotates, it drives the secondary screen 400 to flip, thereby adjusting the pitch angle of the secondary screen 400. To fix the angle of the secondary screen 400, in this embodiment, the flip shaft 310 is a damping shaft. When the rotating component 320 rotates, it drives the secondary screen 400 to rotate relative to the flip shaft 310, enabling the secondary screen 400 to be displayed in landscape or portrait mode, or to rotate the secondary screen 400 to any angle between landscape and portrait mode.

[0047] In this embodiment, when the secondary screen 400 is mounted on the host 100 via the bracket 200 or on a desktop via the bracket 200, the tilt angle of the secondary screen 400 can be adjusted via the flip axis 310 to meet the usage needs of different users; the display angle of the secondary screen 400 can be adjusted via the rotating component 320. For example, the secondary screen 400 can be adjusted to a horizontal display or a vertical display, which not only improves the flexibility and adaptability of the secondary screen 400 to meet different usage scenarios, but also improves the display effect by adjusting the display direction of the secondary screen 400 according to different content.

[0048] In some embodiments, such as Figures 4 to 6 As shown, the adjustment assembly 300 also includes a lower fixing member 330, which is movably connected to the bracket 200 via a flip shaft 310. A rotating member 320 is connected to the lower fixing member 330, meaning the rotating member 320 is connected to the flip shaft 310 via the lower fixing member 330. When the flip shaft 310 rotates relative to the bracket 200, it drives the lower fixing member 330 and the rotating member 320 to rotate together relative to the bracket 200, thereby adjusting the pitch angle of the sub-screen 400 connected to the rotating member 320. In this embodiment, the rotating member 320 is connected to the flip shaft 320 via the lower fixing member 330. Compared to directly connecting the rotating member 320 to the flip shaft 320, this not only facilitates the installation and connection of the rotating member 320 and the flip shaft 310, but also improves the stability and reliability of the connection between the rotating member 320 and the flip shaft 310, effectively reducing the possibility of loosening and failure of the connection.

[0049] In this embodiment, to facilitate the connection between the lower fixing member 330 and the flip shaft 310, two connecting portions 331 protrude from the side of the lower fixing member 330 near the bracket 200. The two connecting portions 331 are spaced apart. The flip shaft 310 passes through the bracket 200 and is rotatable relative to the bracket 200. Both ends of the flip shaft 310 are fixedly connected to one of the connecting portions 331, thereby achieving a fixed connection between the lower fixing member 330 and the flip shaft 310. Alternatively, there may be two flip shafts 310. One end of each flip shaft 310 is rotatably connected to the bracket 200, and the other end of each flip shaft 310 is connected to one of the two connecting portions 331. The connecting portions 331 and the flip shaft 310 can be fixedly connected by bolts, welding, or riveting.

[0050] Furthermore, such as Figure 6As shown, the lower fixing member 330 has a mounting groove 332 on the side away from the bracket 200, and the rotating member 320 is disposed in the mounting groove 332. Specifically, the lower fixing member 330 is a plate-like structure with a certain thickness. One side of the lower fixing member 330 is provided with a mounting groove 332 for mounting the rotating member 320. The rotating member 320 is installed in the mounting groove 332, which not only realizes the installation of the rotating member 320, but also protects the rotating member 320. In addition, it can reduce the overall thickness of the adjustment assembly 300 and realize the miniaturization of the overall structure.

[0051] In some embodiments, such as Figure 6 and Figure 7 As shown, the rotating component 320 includes a bushing 321 and a rotating shaft 322. The bushing 321 is fixedly connected to the flip shaft 310, and the rotating shaft 322 is rotatably connected to the bushing 321. The sub-screen 400 is fixedly disposed relative to the rotating shaft 322. In one example, when the bushing 321 is directly fixedly connected to the flip shaft 310, two connecting parts can be protruded from the side of the bushing 321 near the flip shaft 310. The two connecting parts are spaced apart, and the flip shaft 310 is located between the two connecting parts. The two connecting parts are fixedly connected to both ends of the flip shaft 310, respectively, to achieve a fixed connection between the bushing 321 and the flip shaft 310. In another example, when a lower fixing member 330 is provided between the rotating member 320 and the flipping shaft 310, the bushing 321 is disposed within the mounting groove 332 of the lower fixing member 330 and is fixedly connected to the lower fixing member 330. The rotating shaft 322 is disposed within the bushing 321 and is rotatable relative to the bushing 321. The sub-screen 400 is fixedly disposed relative to the rotating shaft 322. When the rotating shaft 322 rotates relative to the bushing 321, the sub-screen 400 can be rotated in the vertical plane, so that the sub-screen 400 is in a horizontal or vertical state to meet the usage requirements of different scenarios and improve the adaptability of the device. In this embodiment, the rotating shaft 322 and the bushing 321 can achieve a damping effect through friction to fix the angle of the sub-screen 400 after rotation. When the secondary screen 400 needs to be rotated, the user applies an external force to the secondary screen 400, so that the rotating shaft 322 overcomes the friction between itself and the bushing 321 and rotates relative to the bushing 321. After the secondary screen 400 is rotated to the desired position, the external force is removed. The frictional resistance between the rotating shaft 322 and the bushing 321 provides a damping effect, thus fixing the secondary screen 400.

[0052] In other embodiments, the rotating component 320 may consist only of a rotating shaft 322. The rotating shaft 322 can be directly rotatably connected to the lower fixed component 330 or rotatably connected via a bearing to achieve rotation of the sub-screen 400 relative to the lower fixed component 330. When the rotating shaft 322 and the lower fixed component 330 are rotatably connected via a bearing, the outer ring of the bearing is fixedly connected to the lower fixed component 330, and the rotating shaft 322 is fixedly connected to the inner ring of the bearing. The inner ring of the bearing is rotatable relative to the outer ring of the bearing to achieve rotation of the sub-screen 400.

[0053] Furthermore, such as Figures 4 to 6 As shown, the adjustment assembly 300 also includes an upper fixing member 340, which is fixedly connected to the rotating shaft 322, and the sub-screen 400 is fixedly connected to the upper fixing member 340. Compared to a direct connection between the sub-screen 400 and the rotating shaft 322, this embodiment provides an upper fixing member 340 between the sub-screen 400 and the rotating shaft 322. This not only facilitates the installation and connection of the sub-screen 400 and the rotating shaft 322, but also improves the stability and reliability of the connection between the sub-screen 400 and the rotating shaft 322, effectively reducing the possibility of loosening and failure of the connection.

[0054] In this embodiment, both the rotating component 320 and the upper fixing component 340 are circular in shape, and the mounting groove 332 on the lower fixing component 330 is also circular. Both the rotating component 320 and the upper fixing component 340 are disposed in the mounting groove 332 of the lower fixing component 330 to hide the rotating component 320 and the upper fixing component 340. This not only improves the overall aesthetics but also protects the rotating component 320 and the upper fixing component 340.

[0055] like Figure 6 As shown, the upper fixing member 340 is provided with at least one positioning hole 341, and the rotating shaft 322 is provided with at least one positioning post 3221. The at least one positioning post 3221 is adapted to and corresponds one-to-one with the at least one positioning hole 341. By providing positioning holes 341 on the upper fixing member 340 and positioning posts 3221 on the rotating shaft 322, the positioning posts 3221 and positioning holes 341 can play a guiding role when the rotating member 320 and the upper fixing member 340 are assembled. This not only makes it easier for the rotating member 320 and the upper fixing member 340 to be aligned and assembled, improving the assembly effect, but also ensures the relative positional accuracy between the rotating member 320 and the upper fixing member 340, enhancing the connection strength between the rotating member 320 and the upper fixing member 340.

[0056] Furthermore, such as Figure 6 and Figure 7As shown, the outer sidewall of the rotating shaft 322 is provided with a first limiting part 3222 and a second limiting part 3223 spaced apart, and the inner sidewall of the bushing 321 is provided with a third limiting part 3211. The third limiting part 3211 is disposed between the first limiting part 3222 and the second limiting part 3223, and the third limiting part 3211 cooperates with the first limiting part 3222 and the second limiting part 3223 to limit the rotation angle of the rotating shaft 322. Conversely, by providing two limiting parts spaced apart on the bushing 321 and one limiting part on the rotating shaft 322, the rotation angle of the rotating shaft 322 can also be limited.

[0057] This embodiment does not limit the specific positions of the first limiting part 3222 and the second limiting part 3223. The first limiting part 3222 and the second limiting part 3223 can be set at specific positions of the bushing 321 according to actual angle adjustment requirements. For example, the first limiting part 3222 is set at the 0-degree position, the second limiting part 3223 is set at the 90-degree position, and when the third limiting part 3211 abuts against the first limiting part 3222, the sub-screen 400 is just in a horizontal screen state; when the sub-screen 400 is rotated so that the third limiting part 3211 abuts against the second limiting part 3223, the sub-screen 400 rotates from a horizontal screen state to a vertical screen state. It should be noted that the first limiting part 3222 and the second limiting part 3223 can also be set at other angle positions. This is only an example for illustration, and this embodiment of the application is not intended to limit the scope. As a simple variation, a limiting part can be provided on the bushing 321 and two limiting parts can be provided on the rotating shaft 322. The rotation angle of the rotating shaft 322 can be limited by the cooperation between the limiting part on the bushing 321 and the two limiting parts on the rotating shaft 322.

[0058] In some embodiments, such as Figure 1 As shown, the main unit 100 is provided with a plug-in slot 101; the bracket 200 is detachably inserted into the plug-in slot 101, so that the sub-screen 400 is detachably connected to the main unit 100. This embodiment uses a plug-in method to achieve a detachable connection between the bracket 200 and the main unit 100. Compared with the bolt connection, it is not only simple to operate, but also requires no disassembly tools, making assembly simple and quick. In addition, a flip cover can be provided at the opening of the plug-in slot 101 in this embodiment. When the flip cover is open, the bracket 200 can be inserted into the plug-in slot 101. When the bracket 200 is separated from the main unit 100, the flip cover can close the opening of the plug-in slot 101 to protect the internal structure of the main unit 100.

[0059] like Figure 1As shown, the host 100 includes a support base 110 and a main screen 120. The main screen 120 is mounted on the support base 110. The support base 110 has a plug slot 101 on the side opposite to the main screen 120. The secondary screen 400 is positioned opposite to the main screen 120. The support base 110 includes a base 111, a first support part 112, and a second support part 113 connected in sequence. The included angle between the first support part 112 and the second support part 113 is an obtuse angle. The bottom end of the second support part 113 is fixedly connected to the first support part 112. A plug-in slot 101 is provided at the connection between the second support part 113 and the first support part 112. The top end of the second support part 113 is inclined towards the side away from the plug-in slot 101. The main screen 120 is installed on the top end of the second support part 113. After the secondary screen 400 is plugged into the support base 110 through the bracket 200, the main screen 120 and the secondary screen 400 are arranged back to back, that is, the screen of the main screen 120 faces away from the side away from the secondary screen 400, and the screen of the secondary screen 400 faces away from the side away from the main screen 120, so as to display information to users in different positions.

[0060] like Figure 3 As shown, the bottom of the bracket 200 is provided with a first insertion interface 210; the inner bottom surface of the insertion slot 101 is provided with a second insertion interface. When the bracket 200 is inserted into the insertion slot 101, the second insertion interface and the first insertion interface 210 are connected to achieve electrical connection. After the bracket 200 on the sub-screen 400 is inserted into the insertion slot 101, the second insertion interface and the first insertion interface 210 are connected to achieve electrical connection between the sub-screen 400 and the main unit 100. No other interface connection is required, which simplifies the operation and improves the convenience of operation.

[0061] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0062] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
