[0031] In the description of the present disclosure, it is necessary to understand that the orientation or positional relationship indicated by the directional words is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present disclosure and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present disclosure; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0032] With the widespread application of electronic devices, the convenience of their application is increasingly valued by the public. Based on their own structural characteristics, existing laptop computers often need to use external brackets to support the application of laptop computers. The disclosed embodiment provides a hinge device and an electronic device with the hinge device, which is convenient for opening or storing without the help of an external bracket, avoiding cumbersome operations. The hinge device includes but is not limited to applications in laptop computers, tablets or foldable mobile phone terminals, etc.

[0033] The embodiment of the present disclosure takes the application of the hinge device to a laptop as an example to explain the present solution. A laptop generally includes an electronic device screen module and an electronic device system end, both of which can remain closed when powered off or in standby mode, and can also include an open state when in use or in standby mode, that is, the user's use state. In order to adapt to the opening operation of the laptop, the embodiment of the present disclosure provides a hinge device, which can follow the opening action of the electronic device screen module and the electronic device system end, and synchronously provide a stable support for the laptop above the desktop.

[0034] For example, a laptop generally includes: an external structure and an internal structure. The external structure generally includes a housing, a display screen, a keyboard, a touchpad, a power switch and an interface, and the internal structure generally includes a motherboard, a processor, a memory, a hard disk, a graphics card, a sound card, a network card, etc. Among them, the side where the display screen is located is the electronic device screen module, and the side where the keyboard is located is the electronic device system end.

[0035] The present disclosure provides a rotating shaft device 001, referring to Figure 1-Figure 5 , including: a first rotating member 10 and a second rotating member 20, wherein the second rotating member 20 is rotatably sleeved on one end of the first rotating member 10, and the two are coaxially rotatably connected. In actual application, the first rotating member 10 is installed on the electronic device screen module 92, and the second rotating member 20 is installed on the electronic device system end 91. In this way, when the electronic device screen module 92 is opened clockwise relative to the electronic device system end 91, relative rotation can occur between the first rotating member 10 and the second rotating member 20.

[0036] Specifically, the hinge device 001 also includes a connecting rod 30 and a moving rod 50, wherein one end of the connecting rod 30 is rotatably connected to the outer wall of the first rotating member 10, and the other end of the connecting rod 30 is rotatably connected to one end of the moving rod 50, and the moving rod 50 is rotatably connected to at least part of the structure of the second rotating member 20 at the connecting rod fulcrum 40. In this way, the rotation of the first rotating member 10 simultaneously drives the rotation of the connecting rod 30 and the moving rod 50, thereby enabling the moving rod 50 to rotate to a preset angle, thereby achieving stable support for the laptop computer.

[0037] Exemplarily, the side wall of the first rotating member 10 has a first connecting portion 11, and the first connecting portion 11 has a first mounting hole 12 along the axial direction of the first rotating member 10, and one end of the connecting rod 30 is rotatably connected to the first rotating member 10 at the position of the first mounting hole 12. The first mounting hole 12 of the embodiment of the present disclosure includes but is not limited to a through hole, a threaded hole or a countersunk hole. Specifically, the first connecting portion 11 can be a protruding structure protruding from the side wall of the first rotating member 10, and the protruding structure can be directly formed on the side wall of the first rotating member 10, or it can be an external component detachably connected to the side wall of the first rotating member 10.

[0038] Exemplarily, the other end of the connecting rod 30 has a second mounting hole 31 along the axial direction of the first rotating member 10, and the moving rod 50 is at least partially rotatably connected to the connecting rod 30 in the second mounting hole 31, and the moving rod 50 is at least partially rotatably connected to the connecting rod fulcrum 40, wherein the connecting rod fulcrum 40 is arranged away from the outer wall of the second rotating member 20. In this way, it is convenient for the moving rod 50 to rotate along with the rotation of the connecting rod 30, wherein the connecting rod 30 rotates relative to the first rotating member 10 while moving, and the moving rod 50 rotates relative to the connecting rod 30 and the second rotating member 20 at the same time.

[0039] Furthermore, the rotating device of the embodiment of the present disclosure further includes a damping member 60, which can be an elastic body with elastic tensile or compressive properties such as a spring or a spring sheet, or the damping member 60 can also adopt a standard structure with elastic tensile or compressive properties. With the damping member 60, the opening angle of the motion rod 50 is conveniently controlled within the aforementioned preset angle, and the initial reset of the connecting rod 30 and the motion rod 50 relative to the second rotating member 20 and the first rotating member 10 is more convenient.

[0040] In summary, the hinge device 001 of the embodiment of the present disclosure is applied, and the electronic device 002 is a laptop computer as an example. The first rotating member 10 is installed on the electronic device screen module 92, and the second rotating member 20 is installed on the electronic device system end 91. When the laptop computer is changed from a closed state to an open state, the first rotating member 10 rotates following the rotation of the electronic device screen module 92. Since one end of the connecting rod 30 is rotatably connected to the first rotating member 10 at the position of the first mounting hole 12, when the first rotating member 10 rotates, one end of the connecting rod 30 moves and rotates following the first rotating member 10, and the other end of the connecting rod 30 drives one end of the motion rod 50 to rotate and move. At the same time, the motion rod 50 is at least partially rotatably connected to the second rotating member 20 at the connecting rod fulcrum 40. According to mechanical principles, when the first rotating member 10 rotates counterclockwise, one end of the connecting rod 30 rotates following the first rotating member 10, and the other end of the connecting rod 30 drives one end of the motion rod 50 to move toward the first rotating member 10, and the other end of the motion rod 50 rotates clockwise to a preset angle. The preset angle here can be determined according to the actual application angle of the laptop computer, and is not limited here. When the other end of the motion rod 50 rotates clockwise to the preset angle, the other end of the motion rod 50 serves as a fulcrum for supporting the laptop computer, and can firmly support the laptop computer above the desktop, which is convenient for the heat dissipation, and does not require the auxiliary application of other brackets. Furthermore, with the application of the damping member 60, the opening angle of the motion rod 50 is easy to control within the aforementioned preset angle, which is more convenient for the initial reset of the connecting rod 30 and the motion rod 50 relative to the second rotating member 20 and the first rotating member 10.

[0041] The rotating shaft device 001 of the embodiment of the present disclosure further includes a fixed plate 70, which is connected to the side wall of the second rotating member 20, wherein the fixed plate 70 has a first fixed fulcrum 81, which is arranged close to one side of the motion rod 50. The connecting rod 30 has a second fixed fulcrum 82, which is arranged close to one side of the fixed plate 70, and the damping member 60 is fixedly connected between the first fixed fulcrum 81 and the second fixed fulcrum 82. Exemplarily, when the damping member 60 adopts a tension spring, the two ends of the tension spring are respectively firmly connected to the first fixed fulcrum 81 and the second fixed fulcrum 82, so that when the motion rod 50 and the connecting rod 30 rotate, the two will not be separated from each other under the action of the tension spring, and when the laptop computer is closed, the motion rod 50 and the connecting rod 30 can also rotate with it and return to the initial state.

[0042] Specifically, the connecting rod fulcrum 40 protrudes out from the side of the fixed plate 70 close to the moving rod 50, so that the moving rod 50 is rotatably connected with the fixed plate 70 at the connecting rod fulcrum 40. In addition, the fixed plate 70 has a blocking protrusion 71 on the side away from the second rotating member 20. Specifically, the blocking protrusion 71 is located on the side of the connecting rod fulcrum 40 away from the first fixed fulcrum 81, and the blocking protrusion 71 is used to limit the movement rod 50 to rotate to a preset angle. That is, the blocking protrusion 71 is used to limit the maximum angle of the movement rod 50 to rotate counterclockwise. The preset angle of the embodiment of the present disclosure can be determined according to actual application requirements.

[0043] Considering the stable rotation connection between the movement rod 50 and the connecting rod 30, the movement rod 50 has a third mounting hole 51. During actual installation, the third mounting hole 51 and the second mounting hole 31 are locked and installed by a first pin. The movement rod 50 also has a fourth mounting hole 52. During actual installation, the fourth mounting hole 52 and the connecting rod fulcrum 40 are locked and installed by a nut.

[0044] Considering the stable rotation connection between the connecting rod 30 and the first rotating member 10, the connecting rod 30 has a fifth mounting hole 32, which is arranged at one end of the connecting rod 30 close to the first rotating member 10. For example, the fifth mounting hole 32 can be directly formed at one end of the connecting rod 30 close to the first rotating member 10, and an opening is formed. Specifically, the fifth mounting hole 32 is configured as a U-shaped hole.

[0045] In actual application, the second pin is installed in the first mounting hole 12, and the fifth mounting hole 32 forms a decoupling state and a rotational engagement state with the second pin through the aforementioned opening. When the rotation direction of the second pin is consistent with the opening direction of the fifth mounting hole 32, a decoupling state is formed. The damping member 60 is connected between the connecting rod 30 and the fixed plate 70, and the fixed plate 70 is installed on the electronic equipment system end 91 along with the second rotating member 20. Therefore, after the connecting rod 30 and the second pin are in a decoupling state, the connecting rod 30 can be fixed, and the relative position between the connecting rod 30 and the motion rod 50 will not be affected. When the laptop computer is closed, the rotation angle of the first rotating member 10 is reduced and recovered, and the second pin returns to the fifth mounting hole 32, pushing the connecting rod 30 to overcome the tension of the tension spring of the damping member 60, thereby driving the motion rod 50 to recover to the initial state.

[0046] Specifically, a support pad 53 is disposed at one end of the sport bar 50 for support, that is, the support pad 53 is disposed at one end of the sport bar 50 away from the third mounting hole 51. Exemplarily, the support pad 53 can be made of a friction-resistant soft plastic material or a high-strength alloy material.

[0047] Considering the stable installation of the first rotating member 10 relative to the electronic device screen module 92, the first rotating member 10 has a screen module fixing hole 13 along its radial direction, and the first rotating member 10 is installed with the electronic device screen module 92 through the screen module fixing hole 13. Specifically, at least one screen module fixing hole 13 can be provided, and the screen module fixing hole 13 is located on the side of the first connecting portion 11 away from the second rotating member 20.

[0048] Considering the stable installation of the second rotating member 20 relative to the electronic device system end 91, the fixing plate 70 has a system end fixing hole 72, and the fixing plate 70 (the second rotating member 20) is installed on the electronic device system end 91 through the system end fixing hole 72. Specifically, a plurality of system end fixing holes 72 are provided, and each system end fixing hole 72 is dispersedly distributed in a large surface area 73 of the fixing plate 70. Further, the fixing plate 70 is penetrated with a system end fixing hole 72 along the first direction, and the system end fixing hole 72 is used to fix the fixing plate 70 on a plane.

[0049] The disclosed embodiment also provides an electronic device 002 equipped with the above-mentioned rotating device. Taking the electronic device 002 as a laptop computer as an example, the electronic device 002 includes an electronic device system end 91 and an electronic device screen module 92. The fixing plate 70 is installed on the electronic device system end 91 through the system end fixing hole 72, and the first rotating member 10 is installed on the electronic device screen module 92 through the screen module fixing hole 13; the electronic device system end 91 has a shell 93, and the shell 93 has a moving slot 931 for the movement rod 50 to rotate. Exemplarily, the moving slot 931 is a long hole adapted to the movement rod 50 to rotate and extend.

[0050] When the laptop computer is in a closed state, the rotating device is in a closed state as a whole, and the motion rod 50 does not extend out of the motion slot 931. When the laptop computer is opened, the first rotating member 10 rotates with the electronic device screen module 92, and then the connecting rod 30 and the motion rod 50 rotate accordingly. At this time, the motion rod 50 extends out of the motion slot 931 counterclockwise until the motion rod 50 reaches the farthest position, and one end of the supporting foot pad 53 is firmly supported on the desktop, and the laptop computer is firmly supported in the highest position, which is the application position of the laptop computer. In this way, the purpose of lifting the laptop computer can be achieved without the help of an external bracket.

[0051] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps recorded in this disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of this disclosure can be achieved, and this document is not limited here.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present disclosure, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0053] The above is only a specific embodiment of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present disclosure, which should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
