[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0037] Two parts of an electronic device can rotate relative to each other through a hinge structure, and the hinge structure needs to have sufficient damping so that the two parts of the electronic device can remain in the specified position when rotated to the specified position.

[0038] Currently, sufficient damping is achieved by increasing the length of the hinge structure. However, this increase in hinge length leads to an increase in the length of the hinge cover that obscures the hinge structure, thus affecting the visual appearance of the electronic device. For example, a hinge structure includes multiple torsion plates fitted onto a pivot, and also requires a locking cap that engages with one end of the pivot and applies preload to the torsion plates. The preload generates friction between the torsion plates, and the locking cap, in conjunction with the multiple torsion plates, provides damping. However, the locking cap needs to be concealed by the hinge cover, resulting in an increase in the length of the hinge cover, which in turn affects the overall visual appearance of the electronic device.

[0039] This disclosure provides a hinge device and an electronic device. The hinge device may include a pivot structure, a rotation structure, a torsion structure, and a shielding member. The pivot structure may include a first pivot and a second pivot. The first pivot can be connected to a first body of the electronic device (such as a display end with a screen on a laptop computer), and the second pivot can be connected to a second body of the electronic device (such as a system end with an input keyboard on a laptop computer). The rotation structure can be connected to the first pivot and the second pivot respectively, and can allow the first pivot and the second pivot to rotate relative to each other through the rotation structure, thereby realizing the relative rotation of the first body and the second body. The torsion structure can be rotated with friction to the first pivot and the second pivot respectively, so as to provide damping during the relative rotation of the first pivot and the second pivot, so that the first pivot and the second pivot can be stably maintained in the position after rotation. The shielding member is covered on the rotation structure to shield the rotation structure, thereby improving the visual effect of the electronic device. Since the torsion structure provides damping by directly generating friction with the first and second pivots, the setting of pre-tightening force structures such as the snap cap is reduced, which can effectively shorten the axial length of the torsion structure in the pivot structure. This allows the shielding part to cover the torsion structure, and its axial length can be less than the length of the current hinge cover, thus improving the visual effect of the electronic device.

[0040] First aspect

[0041] This disclosure provides a hinge device 10, see [link] Figures 1 to 11 The hinge device 10 may include: a pivot structure 11, a rotation structure 12, a torque structure 13, and a shielding member 14. The pivot structure 11 may include a first pivot 111 and a second pivot 112. The rotation structure 12 may be used to connect the first pivot 111 and the second pivot 112, and the first pivot 111 and the second pivot 112 may rotate relative to each other through the rotation structure 12. The torque structure 13 may have a frictional rotational connection with the first pivot 111 and the second pivot 112. The shielding member 14 may be covered by the rotation structure 12.

[0042] The hinge structure 11, with a first hinge 111 and a second hinge 112, can be parallel to each other, or the extension directions of the first hinge 111 and the second hinge 112 can intersect at infinity, thus allowing them to be considered parallel. The first hinge 111 can be connected to the first body 20 of the electronic device 100, and the second hinge 112 can be connected to the second body 30 of the electronic device 100. During the relative rotation of the first hinge 111 and the second hinge 112, the first body 20 and the second body 30 can also rotate relative to each other, thereby changing the angle between them. For example, the first body 20 can be a display end with a screen in a laptop, and the second body 30 can be a system end with an input keyboard in a laptop. Thus, the opening and closing of the laptop can be achieved through the relative rotation of the first hinge 111 and the second hinge 112. The first pivot 111 and / or the second pivot 112 can be hollow or solid columnar structures. The choice between hollow and solid can adjust the weight, strength, etc. of the hinge device 10.

[0043] The rotating structure 12 can be connected to the first rotating shaft 111 and the second rotating shaft 112 at the same time, and can also make the first rotating shaft 111 rotate relative to the second rotating shaft 112. It can be a gear rotating structure 12, such as the combination of the first gear 121, the second gear 122 and the third gear 123 as described below, or the combination of the fourth gear 124, the fifth gear 125 and the sixth gear 126 as described below.

[0044] Torque structure 13 can be rotatably connected to the first rotating shaft 111 with friction, and can also be rotatably connected to the second rotating shaft 112 with friction, so that frictional resistance can be generated during the relative rotation of the first body 20 connected to the first rotating shaft 111 and the second body 30 connected to the second rotating shaft 112, thereby achieving position holding (such as the first body 20 being able to stay stably in the position after rotation).

[0045] The shielding component 14 can cover and enclose the rotating structure 12 to reduce the entry of dust, foreign objects, etc. into the interior of the rotating structure 12, thereby protecting the rotating structure 12 and reducing the impact of dust, foreign objects, etc. on the smoothness of rotation and accelerated wear of the rotating structure 12. At the same time, it can also improve the overall aesthetics of the electronic device 100, achieving structural enclosure and beautification. The shielding component 14 is a shell structure, which can be a circular cylinder, an elliptical cylinder, or a polygonal cylinder, so as to cover and enclose the rotating structure 12 by fitting it around the rotating structure 12. A gap can be maintained between the shielding component 14 and the rotating structure 12 to avoid interference during the rotation of the rotating structure 12. The shielding component 14 can be made of metal materials (such as stainless steel, aluminum alloy, etc.) or high-strength plastics to have good mechanical strength and corrosion resistance.

[0046] In one example, the laptop computer includes a display and a system. The hinge device 10 may include a pivot structure 11, a rotation structure 12, a torque structure 13, and a shielding member 14. The pivot structure 11 may include a first pivot 111 and a second pivot 112. The first pivot 111 may be connected to the display, and the second pivot 112 may be connected to the system. The rotation structure 12 may be used to connect the first pivot 111 and the second pivot 112, and the first pivot 111 and the second pivot 112 may rotate relative to each other through the rotation structure 12 to change the angle between the display and the system. The torque structure 13 may have a frictional rotational connection with the first pivot 111 and the second pivot 112 to provide frictional resistance during the rotation of the first pivot 111 and the second pivot 112, so that the display can remain in the rotated position after rotating relative to the system. The shielding member 14 may cover the rotation structure 12.

[0047] In this embodiment, the hinge device 10 may include a pivot structure 11, a rotation structure 12, a torque structure 13, and a shielding member 14. The pivot structure 11 may include a first pivot 111 and a second pivot 112. The first pivot 111 may be fixedly connected to the first body 20 of the electronic device 100, and the second pivot 112 may be fixedly connected to the second body 30 of the electronic device 100. The rotation structure 12 may be connected to the first pivot 111 and the second pivot 112 respectively, for supporting and allowing relative rotation between the first pivot 111 and the second pivot 112, thereby realizing the opening and closing movement between the first body 20 and the second body 30; the torque... Structure 13 can be rotatably connected with the first rotating shaft 111 and the second rotating shaft 112 respectively with friction, so as to provide stable damping during the relative rotation of the first rotating shaft 111 and the second rotating shaft 112. This damping can make the first rotating shaft 111 and the second rotating shaft 112 stably maintain their position after rotation, realizing the multi-angle hovering function of the electronic device 100 during the opening and closing process; the shielding member 14 can be covered on the rotating structure 12 (and can extend to cover the partial torsion structure 13) to shield the mechanical components such as the rotating structure 12 and part of the torsion structure 13, prevent dust and foreign objects from entering, and at the same time improve the overall aesthetics of the electronic device 100. Since the torsion structure 13 can provide damping by directly generating friction with the first rotating shaft 111 and the second rotating shaft 112, the setting of the fastening cap can be reduced. Even when the torsion structure 13 is covered, the axial length of the shielding member 14 can still be less than the length of the hinge cover in the prior art, so that the area occupied by the shielding member 14 on the outer surface of the electronic device 100 is extremely small, thereby reducing the impact of the shielding member 14 on the overall appearance and visual effect of the electronic device 100.

[0048] It is understandable that when the area occupied by the shielding member 14 on the outer surface of the electronic device 100 is small, the presence of the shielding member 14 on the outside of the electronic device 100 is weakened, visual interference is reduced, and thus the visual effect of the appearance of the electronic device 100 can be improved.

[0049] In some embodiments, see Figures 1 to 10 At least a portion of the torsion structure 13 in the axial direction of the shaft structure 11 can be exposed outside the shielding member 14.

[0050] The first rotating shaft 111 may have a first axis, which may pass through the center of different radial surfaces of the first rotating shaft 111. The second rotating shaft 112 may have a second axis, which may pass through the center of different radial surfaces of the second rotating shaft 112. The first axis may be parallel to the second axis. The axial direction of the rotating shaft structure 11 may be parallel to the first axis and the second axis, and may be located between the first rotating shaft 111 and the second rotating shaft 112.

[0051] At least a portion of the torsion structure 13 in the axial direction of the shaft structure 11 is exposed outside the shielding member 14, that is, see [link to relevant documentation]. Figure 1 , Figure 2 and Figure 6 A portion of the torsion structure 13 along the axial direction of the shaft structure 11 is covered / blocked by the shielding member 14, and a portion of the portion is exposed outside the shielding member 14, or, see... Figure 8 and Figure 9 The entire section of the torsion structure 13 along the axial direction of the shaft structure 11 is exposed outside the shielding member 14.

[0052] In this embodiment, the torsion structure 13 exposed by the shielding member 14 can be hidden inside the first body 20 and the second body 30, so as to minimize the length of the shielding member 14 in the axial direction of the rotating shaft structure 11, thereby improving the overall appearance and visual effect of the electronic device 100.

[0053] In some embodiments, see Figures 1 to 3 , Figure 8 and Figure 9 The rotating shaft structure 11 may further include two fixing members 15. One fixing member 15 can be fixedly connected to the first rotating shaft 111 and can be used to connect to the first body 20. The other fixing member 15 can be fixedly connected to the second rotating shaft 112 and can be used to connect to the second body 30. In the axial direction of the rotating shaft structure 11, the rotating structure 12, the torsion structure 13, and the two fixing members 15 can be arranged in sequence.

[0054] The fastener 15 can be a plate that can be sleeved on the target rotating shaft (first rotating shaft 111 or second rotating shaft 112) and can be relatively fixed to the target rotating shaft through bonding, welding, or interlocking. The fastener 15 can be connected to the target body (first body 20 or second body 30) by screws, welding, or other means.

[0055] In the axial direction of the rotating shaft structure 11, see Figure 6 and Figure 9 The rotating structure 12, the torsion structure 13, and the two fixing members 15 are arranged in sequence. In this way, the rotating structure 12 and the torsion structure 13 are arranged adjacent to each other, so that the shielding member 14 can cover the rotating structure 12 and part of the torsion structure 13. The part of the torsion structure 13 that is not covered / hidden by the shielding member 14 and the fixing members 15 can be hidden in the first body 20 and the second body 30 at the same time. This can minimize the length of the shielding member 14 in the axial direction of the rotating shaft structure 11, thereby improving the overall appearance and visual effect of the electronic device 100.

[0056] In some embodiments, see Figures 1 to 4 and Figures 6 to 10 The torque structure 13 may include: a first torque part 131 and a second torque part 132. The first torque part 131 may be rotatably connected to the first rotating shaft 111 with friction, and the second torque part 132 may be rotatably connected to the second rotating shaft 112 with friction. The positions of the first torque part 131 and the second torque part 132 may be relatively fixed.

[0057] The first torque part 131 can be fitted onto the first rotating shaft 111 by an interference fit to achieve a frictional rotational connection with the first rotating shaft 111; the second torque part 132 can be fitted onto the second rotating shaft 112 by an interference fit to achieve a frictional rotational connection with the second rotating shaft 112; the first torque part 131 and the second torque part 132 can be connected by a connecting part 133 or limited by a limiting piece 127 to fix their relative positions. The first torque portion 131 may have a first strip-shaped opening 1311 opened along its axial direction, and the inner diameter of the first torque portion 131 may be smaller than the radial dimension of the first rotating shaft 111. Thus, when the first torque portion 131 is fitted onto the first rotating shaft 111, the width of the first strip-shaped opening 1311 can be increased, and the first torque portion 131 can be fitted onto the first rotating shaft 111 with an interference fit. The second torque portion 132 may have a second strip-shaped opening 1321 opened along its axial direction, and the inner diameter of the second torque portion 132 is smaller than the radial dimension of the second rotating shaft 112. Thus, when the second torque portion 132 is fitted onto the second rotating shaft 112, the width of the second strip-shaped opening 1321 can be increased, and the second torque portion 132 can be fitted onto the second rotating shaft 112 with an interference fit.

[0058] When the first body 20 and the second body 30 rotate relative to each other, the first rotating shaft 111 can rotate relative to the first torque part 131 to generate first frictional damping; at the same time, the second rotating shaft 112 can rotate relative to the second torque part 132 to generate second frictional damping; the two damping torques can be superimposed to form the overall torque output of the hinge device 10, thereby achieving a smooth opening and closing feel and a hovering function at any angle.

[0059] In this embodiment, since the first torque part 131 and the second torque part 132 can be directly frictionally connected to the first rotating shaft 111 and the second rotating shaft 112 respectively, and the first torque part 131 and the second torque part 132 are relatively fixed, sufficient frictional damping can be provided during the relative rotation of the first body 20 and the second body 30, and the length of the torque structure 13 in the axial direction of the hinge device 10 can be effectively reduced.

[0060] In some embodiments, see Figures 1 to 4 , Figure 6 and Figure 7The torsion structure 13 may further include a connecting portion 133, wherein the end of the first torsion portion 131 near the rotating structure 12 may be connected to the end of the second torsion portion 132 near the rotating structure 12 via the connecting portion 133, so that the positions of the first torsion portion 131 and the second torsion portion 132 may be relatively fixed; wherein, the shielding member 14 may also cover the connecting portion 133 and the portion where the first torsion portion 131 and the second torsion portion 132 are connected to the connecting portion 133, and allow the portion of the first torsion portion 131 and the second torsion portion 132 not connected to the connecting portion 133 to be exposed from the shielding member 14.

[0061] The first torque section 131 and the second torque section 132 can be arranged in parallel, and their lengths can be approximately the same and opposite to each other. At the same time, one axial end of the first torque section 131 and one axial end of the second torque section 132 can be connected by the connecting part 133 so that the first torque section 131, the second torque section 132 and the connecting part 133 can form a U-shaped torque structure 13 after being connected. The setting of the connecting part 133 can fix the relative positions of the first torque section 131 and the second torque section 132.

[0062] The first torque component 131, the second torque component 132, and the connecting component 133 can be flush or adapted to the contour of the adjacent rotating structure 12; no specific limitation is made here. The materials of the first torque component 131, the second torque component 132, and the connecting component 133 can be the same or different. If they are the same, the first torque component 131, the second torque component 132, and the connecting component 133 can be integrally formed, which can improve the structural strength of the torque structure 13.

[0063] In this embodiment, one axial end of the first torque part 131 and one axial end of the second torque part 132 are connected by a connecting part 133 to achieve relative fixation of the positions of the first torque part 131 and the second torque part 132, and to improve the integration of the torque structure 13 and reduce the amount of assembly work.

[0064] In some embodiments, see Figure 2 , Figure 3 , Figure 6 and Figure 7 The rotating structure 12 may include a first gear 121, a second gear 122, and at least one third gear 123. The first gear 121 may be sleeved on the first rotating shaft 111, the second gear 122 may be sleeved on the second rotating shaft 112, and at least one third gear 123 may mesh with the first gear 121 and the second gear 122 respectively. The first torque portion 131, the second torque portion 132, and the connecting portion 133 may be coplanar on one side of the rotating structure 12 to form a first abutting surface, and the first abutting surface may abut against the first gear 121, the second gear 122, and the third gear 123.

[0065] The first gear 121 can be fixedly mounted on the first rotating shaft 111 relative to the first rotating shaft 111, and the second gear 122 can be fixedly mounted on the second rotating shaft 112 relative to the second rotating shaft 112. The third gear 123 can mesh with the first gear 121 and the second gear 122 respectively. Thus, during the relative rotation of the first rotating shaft 111 and the second rotating shaft 112, the first gear 121 rotates along the third gear 123, and the second gear 122 rotates along the third gear 123.

[0066] The first torque portion 131, the second torque portion 132, and the connecting portion 133 can be coplanar on one side of the rotating structure 12. That is, the first torque portion 131, the second torque portion 132, and the connecting portion 133 can be flush to form a planar first abutting surface on one side of the torque structure 13 corresponding to the rotating structure 12. This first abutting surface can simultaneously abut against the axial end surface of the first gear 121, the axial end surface of the second gear 122, and the axial end surface of the third gear 123.

[0067] In this embodiment, the rotating structure 12 can serve as a support and guide structure during the rotation of the first rotating shaft 111 and the second rotating shaft 112, thereby ensuring a smooth and stable rotation of the first rotating shaft 111 and the second rotating shaft 112. Furthermore, the first gear 121, the second gear 122, and the third gear 123 of the rotating structure 12 abut against the first abutting surface of the torque structure 13, which can further ensure a smooth and stable rotation of the first rotating shaft 111 and the second rotating shaft 112.

[0068] In some embodiments, see Figures 8 to 10 The rotating structure 12 may include: a fourth gear 124, a fifth gear 125, at least one sixth gear 126, and a limiting plate 127. The fourth gear 124 may be sleeved on the first rotating shaft 111, the fifth gear 125 may be sleeved on the second rotating shaft 112, and at least one sixth gear 126 may mesh with the fourth gear 124 and the fifth gear 125 respectively. The limiting plate 127 may be rotatably sleeved on the first rotating shaft 111 and the second rotating shaft 112 respectively, and the second abutting surface on one side of the thickness direction of the limiting plate 127 may abut against the fourth gear 124, the fifth gear 125, and the sixth gear 126 respectively. One end of the first torque part 131 along the axial direction of the rotating shaft structure 11 may be connected to the limiting plate 127, and one end of the second torque part 132 along the axial direction of the rotating shaft structure 11 may be connected to the limiting plate 127, so as to reuse the limiting plate 127 to fix the relative positions of the first torque part 131 and the second torque part 132. The shielding member 14 may expose the torque structure 13.

[0069] The fourth gear 124 can be fixedly mounted on the first rotating shaft 111 relative to the first rotating shaft 111, and the fifth gear 125 can be fixedly mounted on the second rotating shaft 112 relative to the second rotating shaft 112. The third rotating shaft can mesh with the fourth gear 124 and the fifth gear 125 respectively. Thus, during the relative rotation of the first rotating shaft 111 and the second rotating shaft 112, the fourth gear 124 rotates along the sixth gear 126, and the fifth gear 125 rotates along the sixth gear 126.

[0070] The limiting plate 127 can be respectively sleeved on the first rotating shaft 111 and the second rotating shaft 112, so that the first rotating shaft 111 can rotate relative to the limiting plate 127, and the second rotating shaft 112 can rotate relative to the limiting plate 127. One side surface of the limiting plate 127 can simultaneously abut against the fourth gear 124, the fifth gear 125, and the sixth gear 126. One end of the first torque part 131 along the axial direction of the rotating shaft structure 11 and one end of the second torque part 132 along the axial direction of the rotating shaft structure 11 are both connected to the limiting plate 127 to achieve relative fixation of the positions of the first torque part 131 and the second torque part 132; here, see... Figure 10 The first torque part 131 may be provided with a first limiting protrusion 1313, and the second torque part 132 may be provided with a second limiting protrusion 1314. The limiting piece 127 may be provided with a first limiting recess 1271 that adapts to the first limiting protrusion 1313 and a second limiting recess 1272 that adapts to the second limiting protrusion 1314. In this way, when the first limiting protrusion 1313 is located in the first limiting recess 1271 and the second limiting protrusion 1314 is located in the second limiting recess 1272, the limiting piece 127 can be used to fix the relative position of the first torque part 131 and the second torque part 132.

[0071] In this embodiment, the second abutting surface of the limiting piece 127 can simultaneously abut against the fourth gear 124, the fifth gear 125, and the sixth gear 126, which can realize the smooth and stable rotation of the first rotating shaft 111 and the second rotating shaft 112. One end of the first torque part 131 along the axial direction of the rotating shaft structure 11 and one end of the second torque part 132 along the axial direction of the rotating shaft structure 11 can both be connected to the limiting piece 127, so that the limiting piece 127 can be reused to fix the relative positions of the first torque part 131 and the second torque part 132. In this way, the number of structures of the hinge device 10 can be reduced, and the increase in the axial dimension of the hinge device 10 can be further reduced.

[0072] In some embodiments, see Figure 6 and Figure 7The shielding member 14 can be an annular structure with a first opening 141 and a second opening 142 that are interconnected, and a partition member 143 can be provided inside the shielding member 14 to divide the shielding member 14 into a first space 144 with the first opening 141 and a second space 145 with the second opening 142; the first space 144 can be used to accommodate the rotating structure 12; the second space 145 can be used to accommodate the connecting line 40 connecting the first body 20 and the second body 30.

[0073] The first space 144 can accommodate the rotating structure 12, or it can simultaneously accommodate the torsion structure 13 near one end of the rotating structure 12; the second space 145 can accommodate the connecting line 40 connecting the first body 20 and the second body 30 to realize the power and / or data transmission between the first body 20 and the second body 30.

[0074] In this embodiment, the shielding member 14 may be provided with a first space 144 and a second space 145 that are isolated from each other. The first space 144 shields the rotating structure 12 and even the torsional structure 13, and the second space 145 can shield the connecting line 40, so that different structures can be shielded and physically protected by the same structural member.

[0075] Second aspect

[0076] This disclosure provides an electronic device 100, see [link to previous document]. Figure 5 and Figure 11 The electronic device 100 may include: a first body 20, a second body 30, and a hinge device 10. The hinge device 10 may include: a pivot structure 11, a rotation structure 12, a torque structure 13, and a shielding member 14. The pivot structure 11 may include a first pivot 111 and a second pivot 112. The rotation structure 12 may be used to connect the first pivot 111 and the second pivot 112, and the first pivot 111 and the second pivot 112 may rotate relative to each other through the rotation structure 12. The torque structure 13 may have a frictional rotational connection with the first pivot 111 and the second pivot 112. The shielding member 14 may be covered by the rotation structure 12. The first pivot 111 may be connected to the first body 20, and the second pivot 112 may be connected to the second body 30.

[0077] The first body 20 and the second body 30 of the electronic device 100 can be connected by a hinge device 10, and the hinge device 10 can allow the first body 20 and the second body 30 to rotate relative to each other to form a foldable electronic device 100. At the same time, the hinge device 10 can also allow the first body 20 to remain in the rotated position after rotating relative to the second body 30.

[0078] Electronic device 100 can be a laptop computer, music player, etc. For example, see Figure 11The electronic device 100 is a laptop computer, and the first body 20 has a 14-inch or 16-inch display screen; wherein, two shielding members 14 are provided between the first body 20 and the second body 30, and the length of the shielding member 14 in the axial direction of the pivot structure 11 is 24-34mm.

[0079] In this embodiment, since the torsion structure 13 can provide damping by directly generating friction with the first rotating shaft 111 and the second rotating shaft 112, the reliance on the fastening cap can be reduced. Thus, even when the shielding member 14 covers the rotating structure 12, the axial length of the shielding member 14 can still be less than the length of the hinge cover in the prior art, which makes the shielding member 14 occupy a smaller area on the outer surface of the electronic device 100, thereby effectively reducing its impact on the overall visual appearance of the electronic device 100.

[0080] In some embodiments, see Figure 5 and Figure 11 At least a portion of the torsion structure 13 in the axial direction of the shaft structure 11 can be covered by the target portion of the first body 20 and / or the second body 30.

[0081] In other words, the entire torsion structure 13 can be covered by the shielding member 14, or the entire torsion structure 13 can be covered by the shell of at least one of the first body 20 and the second body 30, or the torsion structure 13 can be covered by the shielding member 14 at one end of the axial direction of the shaft structure 11 and by the shell of at least one of the first body 20 and the second body 30 at the other end of the axial direction of the shaft structure 11. Thus, the overall visual appearance of the electronic device 100 can be improved by covering the target portion through the shielding member 14 and / or at least one of the first body 20 and the second body 30.
