[0023] The technical solutions in the application embodiments will be described clearly and completely below with reference to the drawings in the application embodiments. Obviously, the described embodiments are only some of the application embodiments, not all the embodiments. The same or similar reference signs are used to represent the same or similar modules in the drawings. It should be understood that the drawings are only schematic, and the scope of protection of the application is not limited thereto.

[0024] First, the application embodiments in the application embodiments and related professional terms are introduced.

[0025] Many electronic devices use folding design, and folding products are also one of the market trends. Hinge, also known as hinge, pivot, is a kind of connecting element that can provide mutual rotation, which has been widely used in various electronic devices. For example, notebook computers, the display and the main body are connected by hinge structure to realize the opening and closing function. When using the notebook computer, the user can use it after unfolding the display relative to the main body; folding the display and the main body can reduce the space occupied by the notebook computer, which is convenient for the user to collect and carry.

[0026] Due to the need of wiring, additional design space needs to be arranged between the main body and the display. Due to the development requirement of thin type of electronic devices such as notebook computers, the space that can be occupied by the hinge connecting the main body and the display is also becoming smaller. If the space of the shaft cover is limited, the existing hinge arrangement structure cannot be set. The wire fixing hook is arranged on the shaft of the hinge to fix the cable, such as Figure 1As shown, a thread hook is arranged in the extension line direction of the rotating shaft. The rotating shaft provided with the thread hook is usually manufactured by metal power injection molding (MIM) to meet the requirements of complex shape and high strength. The metal power injection molding is a manufacturing process combining the plastic injection molding technology and the powder metallurgy technology, and is mainly used for producing metal parts with complex shape, high precision and high strength. The manufacturing cost of the rotating shaft manufactured by metal power injection molding is several times higher than the cost of turning and computer numerical control (CNC) machining. It can be seen that the thread hook using the MIM rotating shaft has the problem of high processing cost.

[0027] Therefore, it is necessary to design a hinge with a thread function and low processing cost.

[0028] Based on this, the hinge is provided. The hinge can be applied to electronic devices such as notebook computers to realize the folding and rotating functions of the electronic devices. The hinge will be described in detail below. Figure 2 The hinge of the present application is described in detail. As shown in Figure 2 The hinge 200 of the present application can include a rotating shaft 210, a first page plate 220 and a second page plate 230 connected by the rotating shaft 210.

[0029] The rotating shaft 210 can be a cylindrical shaft or a stepped shaft structure. For example, in the stepped shaft structure, the part with a large diameter can be used as a shaft shoulder to limit the relative axial movement of the rotating part on the rotating shaft 210 and the rotating shaft 210.

[0030] In some implementations, the outer diameter of the rotating shaft 210 is usually less than 10 mm to meet the requirements of the thin development of electronic devices. The shaft diameter of the rotating shaft 210 and the first page plate 220 can be, for example, 5 mm, 6 mm, 6.5 mm, etc.

[0031] The first page plate 220 can rotate around the rotating shaft 210. The first page plate 220 can be provided with a first hole part 221, and the first hole part 221 can be sleeved on the rotating shaft 210 to form a hinge structure, or the rotating shaft 210 can be arranged in the first hole part 221 to form a hinge structure. The first page plate 220 is usually a thin plate structure, and the first page plate 220 can be provided with a plurality of second hole parts 222 penetrating through (through) to fix the first page plate 220 and the first assembly (such as a display) of the electronic device. The hole diameter of the second hole part 222 is usually smaller than the hole diameter of the first hole part 221. For example, the diameter of the second hole part 222 can be 2.2 mm to be suitable for the screw thread with M2 specification. The first page plate 220 is usually formed by metal bending and machining the hole part based on the thin plate substrate.

[0032] The second page plate 230 is provided with at least one wire arrangement structure 234 along the axial line direction of the rotation shaft 210. The wire arrangement structure 234 can be a wire arrangement hook or a wire arrangement slot.

[0033] In some implementations, the wire arrangement structure 234 is opposite to the end surface of the rotation shaft 210 along the axial line direction of the rotation shaft 210, the center line of the wire arrangement structure 234 is parallel to the axial line, and the distance between the center line of the wire arrangement structure 234 and the axial line is less than a first preset distance. The normal projection of the cable to be fixed on the cross section of the rotation shaft 210 can be located in a first circle, which is the circle of the maximum cross section of the rotation shaft 210, so as to avoid the influence of the outer contour of the cable on the rotation range of the first page plate 220. The first preset distance can be determined according to the outer diameter of the cable to be fixed and the outer diameter of the rotation shaft 210, for example, the first preset distance can be 1 mm, 1.5 mm, or 2 mm.

[0034] The second page plate 230 is usually a thin plate structure, and the second page plate 230 can be provided with a plurality of third hole portions 231 penetrating through, so as to be fixedly connected with a second component (such as a main body) of the electronic device, and then the first component and the second component can be relatively rotated. The hole diameter of the third hole portion 231 can be the same as or different from the hole diameter of the second hole portion 222. For example, the diameter of the third hole portion 231 can be 2.2 mm, so as to be applicable to a thread with an M2 specification. The second page plate 230 is also usually formed by metal plate bending and machining hole portions based on a thin plate material.

[0035] In some implementations, the second page plate 230 is provided with an extension portion 232 along the axial line direction of the rotation shaft 210, and the extension portion 232 is provided with the at least one wire arrangement structure 234. The wire arrangement structure 234 with a wire arrangement slot or a wire arrangement hook can be manufactured by stamping and folding the edge of the extension portion 232 on the second page plate 230.

[0036] In some embodiments, the second page plate 230 can rotate around the rotation shaft 210. In other embodiments, the second page plate 230 can be fixedly connected with the rotation shaft 210 and cannot rotate around the rotation shaft 210.

[0037] In the embodiments, the wire arrangement structure 234 is arranged on the second page plate 230 along the axial line direction of the rotation shaft 210, and the wire arrangement structure 234 is used for fixing the cable and can realize the wire arrangement function of the hinge. The wire arrangement structure does not need to be arranged on the rotation shaft 210, and the rotation shaft 210 can adopt a conventional cylindrical shaft or a stepped shaft type, which is simple in structure. Then, the rotation shaft 210 can be manufactured by a conventional turning or CNC machining mode, instead of a high-cost metal powder injection molding (MIM) manufacturing mode, that is, the rotation shaft can be manufactured based on a machining mode other than metal powder injection molding, so as to help reduce the machining cost of the wire arrangement hinge.

[0038] The extension 232 is a thin plate extending along the axial line of the rotating shaft 210. If the overhanging extension is too long, the strength of the extension 232 can be affected, and the stability of the wire arrangement structure 234 can also be affected.

[0039] In some implementations, one end of the rotating shaft 210 is a cylindrical shaft, and the other end of the rotating shaft 210 is provided with the first connecting part 212. The first page plate 220 has a first hole part 221, and the cylindrical shaft is arranged in the first hole part 221 of the first page plate 220 to form a hinged structure. The first connecting part 212 is fixedly connected with the extension 232. In this way, the strength and rigidity of the extension 232 can be improved, and the stability of the wire arrangement structure 234 can be maintained.

[0040] In some specific implementations, if the first connecting part 212 covers the axial line of the rotating shaft 210, for example, the cross section (perpendicular to the axial line of the rotating shaft 210) of the first connecting part 212 has a large semicircle profile. The distance between the first side of the first connecting part 212 and the axial line of the rotating shaft 210 is less than a fourth preset distance, and the first side is the side of the first connecting part 212 away from the extension 232. The fourth preset distance can be 1 mm or 1.5 mm, for example. In this way, sufficient space for the cable can be ensured, and the rotation range of the first page plate 220 can be avoided from being affected by the outer periphery of the cable.

[0041] In some embodiments, if the first connecting part 212 has a gap between the first side and the axial line of the rotating shaft 210, for example, the cross section of the first connecting part 212 has a small semicircle profile. The gap between the first side of the first connecting part 212 and the axial line of the rotating shaft 210 is greater than a second preset distance, and the first side is the side of the first connecting part 212 away from the extension 232. In this way, sufficient space for the cable can be ensured, the center line of the cable fixed in the wire arrangement structure 234 can be close to the axial line of the rotating shaft 210, and the floating amount of the cable during the rotation of the first page plate 220 can be reduced. The second preset distance can be determined according to the outer diameter of the cable to be passed and the strength of the first connecting part 212. The second preset distance can be 1.5 mm or 2 mm, for example.

[0042] The first connecting part 212 can be obtained by removing part of the material at one end of the rotating shaft 210. The extension 232 generally has a flat plate structure, and the rotating shaft 210 has a curved surface structure. Therefore, a suitable connection method needs to be adopted to ensure the stability of the connection between the extension 232 and the rotating shaft 210.

[0043] In some implementations, the first joint part 212 can have a cross section (perpendicular to the axial direction of the rotating shaft 210) in the shape of a circular arc, and the circular arc-shaped first joint part 212 can be obtained by removing part of the rotating shaft 210 in the axial direction. The extension part 232 can have a circular arc shape with a curvature matching that of the circular arc-shaped first joint part 212. For example, the circular arc-shaped extension part 232 can be obtained by stamping (or bending) a flat plate-shaped extension part. The first joint part 212 and the extension part 232 can be fixedly connected by a continuous curved surface, and the connection is stable and reliable.

[0044] In some implementations, the first joint part 212 can have a cross section (perpendicular to the axial direction of the rotating shaft 210) in the shape of a circular arc, and the circular arc-shaped first joint part 212 can be obtained by removing part of the rotating shaft 210 in the axial direction. The extension part 232 can have a circular arc shape with a curvature matching that of the circular arc-shaped first joint part 212. For example, the circular arc-shaped extension part 232 can be obtained by stamping (or bending) a flat plate-shaped extension part. The first joint part 212 and the extension part 232 can be fixedly connected by a continuous curved surface, and the connection is stable and reliable.

[0045] Generally, the rotating shaft 210 has a small size, and the space available for the accessories for fixedly connecting the first joint part 212 and the extension part 232 is limited, otherwise, the space for wiring will be occupied. For example, if a bolt is used for fixation, the space for wiring will be occupied. If a counterbore screw is used for fixation, the first joint part 212 and the extension part 232 are too thin.

[0046] In some implementations, the first joint part 212 and the extension part 232 can be fixedly connected by riveting or metal adhesive, which is simple, occupies little space, and helps to ensure sufficient space for wiring. Compared with welding, riveting or metal adhesive fixation also helps to reduce the deformation of parts.

[0047] The wire arrangement structure 234 with a wire arrangement groove can be made by stamping and folding the edge of the extension part 232 on the second page plate 230.

[0048] In some implementations, the extension part 232 is provided with a protruding part 233, the edge of the extension part 232 is folded to form the protruding part 233, and the end surface of the protruding part 233 is perpendicular to the axial direction. The protruding part 233 is provided with an open groove to form the wire arrangement structure 234, for example, the wire arrangement structure 234 is formed by stamping the open groove on the protruding part 233. For example, the protruding part 233 can be formed by folding the tail edge of the extension part 232, and the end surface of the protruding part 233 is perpendicular to the axial direction, so that the material utilization rate is high and the amount of removed material is small. For another example, the protruding part 233 can be formed by folding the side edge of the extension part 232.

[0049] The cable management structure 234 should not be too large, so as not to affect the rotational movement of the first page 220 and the first component connected to it.

[0050] In some implementations, the outer contour of the protrusion 233 can be rectangular or U-shaped. For example, the outer contour of the protrusion 233 can be rectangular, allowing for direct bending and reducing processing steps. Alternatively, the outer contour of the protrusion 233 can be circular, retaining more material and improving the strength of the wiring structure. The orthographic projection of the first portion of the protrusion 233 onto the maximum cross-section of the rotating shaft 210 lies within the first circumference. The first portion is the part of the protrusion 233 that is far from the extension 232 and extends beyond the first joint 212. The first circumference is the circumference of the maximum cross-section of the rotating shaft 210. Taking the second page 230 as the lower part and the rotating shaft 210 as the upper part, the first portion of the protrusion 233 is the part of the plate higher than the first joint 212, and its orthographic projection onto the maximum cross-section of the rotating shaft 210 lies within the first circumference. That is, the vertex of the protrusion 233 is not higher than the vertex of the pivot 210, and the left and right sides of the protrusion 233 are located within the first circumference of the pivot 210. In some specific implementations, multiple vertices of the rectangular protrusion 233 can be chamfered or rounded to prevent the orthographic projection of the vertices on the cross-section of the pivot 210 from exceeding the first circumference, thus retaining more material and improving the strength of the wiring structure. Viewed along the axial direction of the pivot 210, since the outline of the protrusion 233 is located within the cross-sectional outline of the pivot 210, it will not affect the rotational movement of the first page 220 and the first component connected to it.

[0051] In some implementations, the centerline of the slot coincides with the axis of the rotating shaft 210, that is, the centerline of the cable management structure 234 coincides with the axis of the rotating shaft 210. This helps to provide more space for cable routing and reduce the amount of floating of the cable fixed in the cable management structure 234 during hinge rotation. The slot of the cable management structure 234 can be circular or U-shaped. In some embodiments, if the slot is circular, the size of the notch 235 of the slot can be less than or equal to the diameter of the slot. For example, the size of the notch 235 can be slightly smaller than the diameter of the slot, which helps to prevent the cable from coming out of the slot and ensures a secure fixation.

[0052] The direction of the notch 235 in the opening slot can be set as needed. For example... Figure 2 As shown, the notch 235 of the opening groove is parallel to the centerline of the third hole, and the shape of the opening groove is circular. Figure 3 As shown, the notch 235 of the opening groove is perpendicular to the centerline of the third hole, and the shape of the opening groove is U-shaped. Typically, the centerline of the third hole is perpendicular to the axis of the rotating shaft 210.

[0053] Figure 4 is Figure 3 the wiring diagram of the hinge. As shown in Figure 4 , the cable fixing structure 234 on the second page plate 230 can fix the cable thereon, and the cable fixing groove 224 on the first page plate 220 can fix the cable thereon. Thus, when the first page plate 220 rotates relative to the second page plate 230, the floating amount of the cable can be reduced.

[0054] In some implementations, the width dimension of the extension 232 is associated with the outer diameter dimension of the rotating shaft 210, or in other words, the width dimension of the extension 232 is determined based on the outer diameter dimension of the rotating shaft 210. Specifically, the difference between the width of the extension 232 and the outer diameter of the rotating shaft 210 is less than a third preset distance, which is determined according to the strength of the extension 232 and the outer profile of the extension 232 does not affect the rotation of the first page plate, and the third preset distance can be, for example, 2 mm, 2.5 mm. Generally, the extension 232 is located between the axis of the rotating shaft 210 and the body of the second page plate 230. In some embodiments, the width of the extension 232 can be less than or equal to the outer diameter dimension of the rotating shaft 210. In other embodiments, the width of the extension 232 can be greater than the outer diameter dimension of the rotating shaft 210. For example, the width of the extension 232 can be 2 mm greater than the outer diameter of the rotating shaft 210, which helps to improve the strength of the extension itself.

[0055] In some implementations, the rotating shaft 210 can further be provided with at least one boss 214, and the first page plate 220 can be provided with a stopper 223, and the boss and stopper structure is used to limit the rotation range of the first page plate 220 relative to the second page plate 230. As shown in Figure 2 , when the stopper 223 contacts the surface of the boss 214, the rotation of the first page plate 220 relative to the rotating shaft 210 can be limited, preventing the three-dimensional space between the first page plate 220 and the second page plate 230 from being too small, so as to avoid damaging the connected electronic product and reducing the floating amount of the cable.

[0056] In the embodiments of the present application, the cable fixing structure 234 for fixing the cable is arranged on the second page plate 230, and the center line of the cable fixing structure 234 is parallel to and close to the axis of the rotating shaft 210, which can realize the cable fixing function of the hinge. The rotating shaft 210 can adopt a conventional cylindrical shaft or a stepped shaft type without the need to arrange a cable fixing structure on the rotating shaft 210, and the structure is simple. Furthermore, the rotating shaft 210 can be manufactured by a conventional turning or CNC machining method, instead of a high-cost metal powder injection molding method, thereby helping to reduce the processing cost of the cable fixing hinge.
