[0002] With the continuous development of technology, electronic products need to meet more usage modes. Among them, the hinge structure can realize the angle switching of the product. In order to meet more usage modes, the hinge needs to be able to rotate 360 ​​degrees.

[0003] Existing 360-degree rotating structure generally includes two rotating shafts, which are connected to electronic products through connectors. The two rotating shafts cooperate through gear assemblies 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, high cost, and its longitudinal height is relatively high, making it difficult to make the product thinner and lighter. Utility Model Content

[0005] To address at least the above-mentioned technical problems existing in the prior art, this application provides a rotating shaft structure and an electronic product.

[0006] This application provides a rotating shaft structure, including a slide rail assembly, a rotating shaft assembly, and a torque assembly. The slide rail assembly includes a linear toothed plate and a slide rail body. The slide rail body is located on one long side of the linear toothed plate and includes a strip-shaped hole arranged along the length direction of the linear toothed plate. The rotating shaft assembly includes a rotating shaft body and a gear. The gear is disposed on the rotating shaft body, the rotating shaft body passes through the strip-shaped hole, and the gear meshes with the linear toothed plate. The rotating shaft body drives the gear to rotate on the linear toothed plate. The torque assembly is disposed on the rotating shaft body and located on the side of the slide rail body away from the gear. The torque assembly includes a torque portion and an abutment portion. The abutment portion is located between the torque portion and the slide rail body. The torque portion abuts against one side of the abutment portion to generate torque, and the other side of the abutment portion abuts against the slide rail body.

[0007] In some embodiments, the abutment portion includes a protruding structure; the protruding structure passes through the strip hole, and the side end of the protruding structure is in contact with the inner wall of the strip hole.

[0008] In some embodiments, the abutting portion further includes an annular structural member, which is sleeved on the rotating shaft body; the annular structural member has the protrusion structure on the side that abuts against the slide rail body.

[0009] In some embodiments, the torque section includes multiple torque plates and a torque nut, with the multiple torque plates stacked along the axial direction of the rotating shaft body; the torque nut is screwed to the rotating shaft body, and the torque plates abut against the annular structure through the torque nut.

[0010] In some embodiments, the shaft assembly further includes a first connecting piece; the gear is located in the middle of the shaft body, and the torque assembly is disposed on one side of the gear on the shaft body, and the first connecting piece is disposed on the other side.

[0011] In some embodiments, the slide rail assembly further includes a rotating channel and a second connecting piece. The rotating channel has an oblong cross-sectional shape and is sleeved on the outside of the linear toothed plate and the slide rail body.

[0015] In another aspect, this application also provides an electronic product, including a display terminal, a system terminal, and the aforementioned hinge structure; the hinge assembly is connected to the display terminal, and the slide rail assembly is connected to the system terminal.

[0016] This application provides a rotating shaft structure and electronic product in which a gear meshes with a linear gear plate, and the gear can rotate on the linear gear plate. As the gear rotates, a wide range of angle adjustments can be achieved for the rotating shaft body, such as 360-degree rotation. During rotation, the torque component abuts against the contact component, generating greater torque between them. Combined with the meshing between the gear and the linear gear plate, this improves the stability of the rotating shaft structure during rotation.

[0032] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] This application provides a rotating shaft structure, including a slide rail assembly, a rotating shaft assembly, and a torque assembly. The slide rail assembly and the rotating shaft assembly work together to achieve a large rotation range, such as 360-degree angle adjustment. The torque assembly provides torque to the rotating shaft structure to ensure stable operation of the rotating shaft structure.

[0034] The following describes in detail, with reference to the accompanying drawings, the components of the rotating shaft structure provided in the embodiments of this application, the positional relationships between the components, and the connection relationships.

[0035] like Figures 1 to 3 As shown in the embodiment of this application, the slide rail assembly 10 includes a linear toothed plate 11 and a slide rail body 12. The slide rail body 12 is an annular sheet structure, which includes a strip hole 13. The strip hole 13 is used to connect with the rotating shaft assembly 20 and has a limiting function for the rotating shaft assembly 20. The strip hole 13 includes two long sides. The linear toothed plate 11 is located on one long side of the slide rail body 12. The linear toothed plate 11 is arranged along the length direction of the slide rail body 12. The rotating shaft assembly 20 passes through the strip hole 13 and moves along the length direction of the linear toothed plate 11. During the movement, the rotating shaft assembly 20 is limited within the strip hole 13.

[0036] For example, the slide rail assembly 10 includes a rotation channel 14, which is sleeved on the outside of the linear toothed plate 11 and the slide rail body 12. The rotation channel 14 forms a protective structure, preventing the linear toothed plate 11 and other structures from being exposed. The rotating shaft assembly 20 is located within the rotation channel 14 and completes its rotation. For example, the cross-sectional shape of the rotation channel 14 is waist-shaped, with two parallel long sides and two arched sides. The linear toothed plate 11 is located on one of the long sides of the rotation channel 14.

[0037] For example, the length of the straight toothed plate 11 is the same as the length of the long side on the same side, and the length of the straight toothed plate 11 is determined according to the rotation angle requirements of the rotating shaft assembly 20; for example, the rotating shaft structure needs to meet the requirement of 360-degree rotation, therefore, the length of the straight toothed plate 11 needs to meet the stroke requirement of the rotating shaft assembly 20 to rotate 360 ​​degrees. For example, when the rotating shaft assembly 20 completes a 360-degree rotation, the rotating shaft assembly 20 rotates from one end of the straight toothed plate 11 to the other end.

[0038] Continue to refer to Figures 1 to 3As shown, the slide rail assembly 10 also includes an extension sleeve 16; the extension sleeve 16 is located at the side end of the rotation channel 14 and extends along the width direction of the rotation channel 14, and the shaft assembly 20 and the torque assembly 30 thereon are located inside the extension sleeve 16.

[0039] The extension sleeve 16 acts as a cover for the shaft, placing most of the shaft structure inside the extension sleeve 16. This prevents the rotating parts of the shaft structure from being exposed, thus improving the aesthetics of the shaft structure and preventing it from getting tangled with other structures, thereby enhancing the safety of the shaft structure during use.

[0040] In this embodiment, a second connecting piece 15 is provided on the outer wall of the rotating channel 14, and is fixedly connected to the structure whose rotation angle needs to be adjusted via the second connecting piece 15. The second connecting piece 15 is perpendicularly connected to the outer wall of one of the long sides of the rotating channel 14. For example, the width of the second connecting piece 15 is not larger than the width of the rotating channel 14.

[0041] like Figure 1 , Figure 2 and Figure 4 As shown in the embodiment of this application, the rotating shaft assembly 20 includes a rotating shaft body 21 and a gear 22. The gear 22 is disposed on the rotating shaft body 21. The rotating shaft body 21 passes through the strip hole 13, and the gear 22 meshes with the linear gear plate 11. The rotating shaft body 21 drives the gear 22 to rotate on the linear gear plate 11.

[0042] For example, one side of the gear 22 is limited by the slide rail body 12, and the other side can be provided with an independent limiting baffle. The limiting baffle and the slide rail body 12 cooperate to limit the gear 22 on the straight tooth plate 11.

[0043] For example, gear 22 is located in the middle of the rotating shaft body 21. Torque assembly 30 is provided on one side of the rotating shaft body 21 with gear 22, and first connecting piece 23 is provided on the other side. The structure whose rotation angle needs to be adjusted is connected through the first connecting piece 23. Through the cooperation of gear 22 and linear gear plate 11, the rotating shaft body 21 is rotated relative to slide rail assembly 10 by a certain angle, thereby realizing the rotation of the structure connected by the first connecting piece 23 and the second connecting piece 15 by a certain angle.

[0044] like Figure 1 , Figure 2 and Figure 5 As shown in the embodiment of this application, the torque component 30 is disposed on the rotating shaft body 21 and located on the side of the slide rail body 12 away from the gear 22. The torque component 30 includes a torque part 31 and an abutment part 32. The abutment part 32 is located between the torque part 31 and the slide rail body 12. The torque part 31 abuts against one side of the abutment part 32 to generate torque, and the other side of the abutment part 32 abuts against the slide rail body 12.

[0045] For example, the torque section 31 includes multiple torque plates 311 and a torque nut 312. The multiple torque plates 311 are stacked along the axial direction of the shaft body 21. The torque nut 312 is screwed to the shaft body 21, and the torque plates 311 abut against the annular structure 322 through the torque nut 312.

[0046] For example, the abutment portion 32 includes an annular structural member 322, which covers and is sleeved on the rotating shaft body 21. There is a certain friction between the abutment portion 32 and the rotating shaft body 21, which can further increase the torque value between the rotating shaft body 21 and the torque assembly 30. The annular structural member 322 cooperates with the torque nut 312 and applies axial compressive force to multiple torque plates 311, which can increase the friction between the torque plates 311 and the rotating shaft body 21, and can also further increase the torque value between the rotating shaft body 21 and the torque assembly 30.

[0047] For example, the annular structural member 322 has an opening and is deformable. The annular structural member 322 covers the rotating shaft body 21 through the opening, and the annular structural member 322 hugs the rotating shaft body 21, so that there is a certain friction between the two. In this embodiment of the application, the material of the annular structural member 322 is not limited.

[0048] Continue to refer to Figure 1 , Figure 2 and Figure 5 As shown in the embodiment of this application, the abutting part 32 includes a protruding structure 321; the protruding structure 321 passes through the strip hole 13, and the side end of the protruding structure 321 is in contact with the inner wall of the strip hole 13. Specifically, the protruding structure 321 is provided on the side of the annular structure 322 that abuts against the slide rail body 12. When the rotating shaft structure rotates, the protruding structure 321 is engaged in the strip hole 13, so that the annular structure 322 cannot rotate synchronously with the rotating shaft body 21, which can ensure that the annular structure 322 generates friction with the annular structure 322.

[0049] When the rotating shaft structure is in use, the rotating shaft body 21 and the slide rail assembly 10 are connected to the structure that requires the adjustment angle. When a force is applied to the rotating shaft body 21 or the slide rail assembly 10, the gear 22 on the rotating shaft body 21 slides along the straight toothed plate 11. After reaching the required position, the torque component 30 provides torque to keep the rotating shaft structure in the current angle state.

[0050] This application provides an electronic product including the aforementioned hinge structure. The electronic product includes a structure requiring angle adjustment, which is achieved through the hinge structure. For example, the electronic product includes a display terminal, a system terminal, and the aforementioned hinge structure; the hinge assembly 20 is connected to the display terminal, and the slide rail assembly 10 is connected to the system terminal.

[0051] like Figure 6As shown, when the hinge structure is at 0 degrees, the display and system are off, and the laptop is in a 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, such as... Figure 7 As shown in the image; when the laptop requires 180-degree or 360-degree rotation, the display can be rotated further to the desired angle, such as... Figure 8 The state shown. In this embodiment of the invention, the rotation angle of the rotating shaft structure is not limited to a fixed angle, but can be any angle within a 360-degree range.

[0052] This application provides a rotating shaft structure and electronic product. A gear 22 meshes with a linear gear plate 11, and the gear 22 can rotate on the linear gear plate 11. With the rotation of the gear 22, a large-angle adjustment range of the rotating shaft body 21 can be achieved, such as 360-degree rotation. During rotation, the torque part 31 abuts against the abutment part 32, generating greater torque between them. Combined with the meshing between the gear 22 and the linear gear plate 11, this improves the stability of the rotating shaft structure during rotation. The technical solution of this application enables large-angle rotation adjustment, and during rotation, the rotating shaft assembly 20 and the slide rail assembly 10 cooperate stably, effectively improving the stability of the rotating shaft structure during use.
