For example, in a laptop computer, the system end and the display end are connected by a hinge structure, which can realize the relative angle adjustment between the system end and the display end, such as completing the opening / closing operation of the laptop computer. With the development of technology, electronic products need to meet different usage modes, requiring the system end and the display end to be able to be adjusted to more opening and closing angles through the hinge structure.

[0003] At present, the system end and the display end of a laptop computer can be connected through a 360-degree hinge structure, and the display end and the system end can be adjusted to different angles according to the usage mode of the laptop computer. The existing 360-degree hinge structure generally includes two rotating shafts, which are respectively connected to the display end or the system end through a connecting piece, and the two rotating shafts are matched through a gear assembly to achieve 360-degree rotation.

[0004] However, the 360-degree rotating shaft structure with two rotating shafts is relatively complex and redundant, has poor stability, and is costly. In addition, the longitudinal height of the rotating shaft structure is relatively high, which makes it difficult to make the product thinner and lighter. Summary of the invention

[0005] In order to solve at least the above technical problems existing in the prior art, the present invention provides a rotating shaft structure and an electronic product.

As the gears rotate, the gears move relatively on the linear toothed plate until the shaft body rotates 360 degrees. During the rotation process, the torsion assembly provides axial torque to ensure that the shaft assembly remains at the rotation angle. The technical solution of the present invention can achieve coordinated rotation of the shaft structure through the cooperation of the gears and the linear toothed plate, and improve the stability of the shaft structure and the smoothness of rotation.

[0031] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] An embodiment of the present invention provides a rotating shaft structure, including a rotating shaft assembly, a slide rail assembly and a torque assembly; the rotating shaft assembly is a single rotating shaft structure, and the gears on the single shaft structure cooperate with the slide rail assembly to achieve multi-angle rotation up to 360 degrees, and the torque assembly provides torque during rotation so that the rotating shaft assembly can maintain the current angular position.

[0033] The components of the rotating shaft structure provided by the embodiment of the present invention, as well as the positional relationship and connection relationship of the components are described in detail below in conjunction with the accompanying drawings.

[0034] like Figures 1 to 7 As shown, in the embodiment of the present invention, the shaft assembly 10 includes a shaft body 11, a gear 12 and a first connecting piece 13. The shaft body 11 has a certain length, and the gear 12 is arranged at a center or near the center of the shaft body 11. One side of the gear 12 on the shaft body 11 is connected to the first connecting piece 13, and the other side is used to connect to the torque assembly 30.

[0035] One side of the rotating shaft body 11 is in the shape of a sheet, and a mounting hole is provided on the sheet structure. A mounting hole is also provided on the first connecting plate 13. The mounting holes on the two structures are superimposed and fixedly connected by fastening bolts. The other side of the rotating shaft body 11 is connected to the torsion assembly 30. The specific connection method will be described later.

[0036] Continue to refer Figures 1 to 7As shown, in the embodiment of the present invention, the slide rail assembly 20 includes a rotating channel 23, a linear tooth plate 21 and a second connecting plate 22, wherein the cross-sectional shape of the rotating channel 23 is waist-shaped, and one of the long sides of the rotating channel 23 is the linear tooth plate 21, that is, teeth are arranged along the length direction on the inner side of one of the long sides of the rotating channel 23 to form a linear tooth plate 21, and the rotating shaft body 11 passes through the rotating channel 23, and the gear 12 is located in the rotating channel 23. When the rotating shaft body 11 rotates, the gear 12 is located in the rotating channel 23 and rotates along the linear tooth plate 21.

[0037] For example, the starting position of the gear 12 is located at one end of the linear gear plate 21; when the gear 12 rotates 360 degrees, the gear 12 rotates from one end of the linear gear plate 21 to the other end. When the shaft body 11 and the gear 12 rotate synchronously, the gear 12 will produce relative movement on the linear gear plate 21, and the length of the linear gear plate 21 needs to meet the movement requirements of the shaft body 11 and the gear 12, that is, as the shaft body 11 rotates, the linear gear plate 21 needs to meet the movement distance of the gear 12. However, if the linear gear plate 21 is too long, it will affect the appearance of the electronic product connected to it. Therefore, when rotating 360 degrees, the gear 12 rotates from one end of the linear gear plate 21 to the other end, which not only meets the functional requirements, but also saves the space occupied by the rotating channel 23. Compared with the existing dual-axis shaft structure, its height (length) can be reduced by at least 1 mm.

[0038] In the embodiment of the present invention, the rotating channel 23 includes an insertion end and an exit end of the rotating shaft body 11, and the exit end is provided with an annular protrusion 24 for limiting the gear 12; one side end of the gear 12 abuts against one side of the annular protrusion 24, and the torque assembly 30 abuts against the other side of the annular protrusion 24.

[0039] The insertion end and the exit end form a movable space for the gear 12 , wherein an annular protrusion 24 is provided at the exit end, and the annular protrusion 24 forms a through-hole, through which the shaft body 11 can pass but the gear 12 can be limited.

[0040] In the embodiment of the present invention, the other side of the rotating shaft body 11 located at the gear 12 is connected to the torque assembly 30, and the torque assembly 30 abuts against the slide rail assembly 20 to generate torque. For example, the torque assembly 30 includes a plurality of torque plates 31 and a torque nut 32, and the plurality of torque plates 31 are stacked and arranged along the axial direction of the rotating shaft body 11; the torque nut 32 is threadedly connected to the rotating shaft body 11, and the torque plate 31 abuts against the annular protrusion 24 through the torque nut 32.

[0041] For example, the shaft body at the position where the shaft body 11 connects to the torsion plate 31 is non-circular, and the corresponding through hole of the torsion plate 31 is also non-circular. The two are mutually engaged to prevent the torsion plate 31 from generating relative rotation in the circumferential direction of the shaft body 11.

[0042] Continue to refer Figures 1 to 7 As shown, in the embodiment of the present invention, the slide rail assembly 20 also includes a baffle 25, which is arranged at the insertion end and is detachably connected to the insertion end, and the side of the gear 12 away from the annular protrusion 24 abuts against the baffle 25; the baffle 25 includes a strip guide hole 251, and the strip guide hole 251 is used to limit the moving path of the rotating shaft body 11.

[0043] The strip guide hole 251 has a certain length for the movement of the shaft body 11, and the width of the strip guide hole 251 is the same as the outer diameter of the shaft body 11, and is used to limit the rotation of the shaft body 11 along the width direction. The baffle 25 cooperates with the annular protrusion 24 to limit the gear 12 in the rotation channel 23.

[0044] In the embodiment of the present invention, the protruding end of the rotating channel 23 includes a sleeve structure 26 extending in the width direction; the torsion assembly 30 is arranged in the sleeve structure 26, and the end of the rotating shaft body 11 is located in the sleeve structure 26. By providing the sleeve structure 26, the rotating channel 23 is provided as an integral structure, so that the torsion assembly 30 is not exposed, and the aesthetics of the rotating shaft structure is improved.

[0045] For example, the second connecting piece 22 is vertically connected to the outer wall of one of the long sides of the rotating channel 23 and the sleeve structure 26. The width of the second connecting piece 22 is not greater than the width of the rotating channel 23 and the sleeve structure 26.

[0046] An embodiment of the present invention provides an electronic product, including the above-mentioned hinge structure; or, an embodiment of the present invention provides an electronic product, including the above-mentioned hinge structure, a display end and a system end; the first connecting piece 13 of the hinge structure is connected to the display end, and the second connecting piece 22 of the hinge structure is connected to the system end.

[0047] Taking a laptop computer as an example, when adjusting the opening and closing angle of the laptop computer, the display end is generally moved. Therefore, the display end is connected to the first connecting piece 13, and the first connecting piece 13 is rotated by the display end, and the corresponding gear 12 rotates synchronously. The display end, the shaft body 11 and the gear 12 rotate synchronously, wherein the gear 12 rotates in coordination with the linear gear plate 21 to realize the opening and closing adjustment of the display end and the system end.

[0048] like Figure 5 As shown, when the hinge structure is in the 0 degree state, the display end and the system end are closed, and the laptop is in the closed state; when the laptop is used in normal mode, the hinge structure is opened to 90 degrees, or an angle close to 90 degrees; when the laptop needs to be rotated 180 degrees or 360 degrees, the display end can be further rotated to the corresponding angle, and the hinge structure is as shown in FIG. Figure 6 and Figure 7 shown.

[0049] In the embodiment of the present invention, the rotation angle of the rotating shaft structure is not limited to a fixed angle, and can be any angle within the range of 360 degrees.

[0050] The present invention provides a shaft structure and electronic product. When in use, the shaft body 11 is driven to rotate, which drives the gear 12 on the shaft body 11 to rotate synchronously. As the gear 12 rotates, the gear 12 moves relatively on the linear tooth plate 21 until the shaft body 11 rotates 360 degrees. During the rotation process, the torque assembly 30 provides axial torque to ensure that the shaft assembly 10 remains at the rotation angle. The technical solution of the present invention can achieve coordinated rotation of the shaft structure through the cooperation of the gear 12 and the linear tooth plate 21, and improve the stability of the shaft structure and the smoothness of rotation. Compared with the existing dual-axis shaft structure, it effectively reduces the height (length) of the shaft structure, reduces the number of shaft structure components, and effectively reduces the cost of use.
