[0002] With the development of flexible display technology and the combination of portability (compared to ordinary electronic devices) and the ultimate experience of large-screen display when unfolded, foldable electronic devices have gradually become an important trend in mobile terminal development and a key area of ​​competition among major terminal manufacturers. For foldable electronic devices, the hinge structure is crucial, as its performance directly affects the product's functionality and user experience.

[0042] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0043] The following is a reference appendix. Figures 1 to 4 This disclosure describes a hinge, a display module, and an electronic device according to embodiments thereof.

[0044] like Figures 1 to 4 As shown, the hinge according to an embodiment of the present disclosure includes: a base 1 and a rotating component 2. The base 1 extends along a first direction. The rotating component 2 includes a float 22 and a rotating assembly 21. The float 22 is provided with a first mounting position 221 and a second mounting position 222 arranged at intervals along a second direction. The second direction is orthogonal to the first direction. One end of the rotating assembly 21 is pivotally connected to the base 1, and the other end of the rotating assembly 21 is pivotally connected to the first mounting position 221 and the second mounting position 222. The rotating assembly 21 is slidable relative to the second mounting position 222 along the second direction.

[0045] Understandably, the first direction is Figure 2 The A direction is the length direction of base 1. The second direction is... Figure 2The B direction refers to the width direction of the float 22. When the hinge is folded, the float 22 rotates axially about the first direction, and the second direction can always be orthogonal to the first direction. It should be noted that the first direction can be either the length or width direction of the base 1. Figure 2 The scenarios shown are merely examples and not limitations; the embodiments disclosed herein are not limited to these examples. Figure 2 The situation shown.

[0046] According to the embodiments of the present disclosure, since the other end of the rotating component 21 is pivotally connected to the first mounting position 221 and the second mounting position 222, and the rotating component 21 is slidable relative to the second mounting position 222 in the second direction, the display module or electronic device using this hinge can better support the screen through the floating plate 22 when folded or unfolded, so that the floating plate 22 has a high degree of fit with the screen and good flatness.

[0047] It is understandable that, such as Figures 1 to 4 As shown, the second mounting position 222 is closer to the base 1 than the first mounting position 221. When the rotating component 21 rotates relative to the base 1 in the first direction, the rotating component 21 can rotate relative to the first mounting position 221 of the floating plate 22. The rotating component 21 can rotate relative to the second mounting position 222 of the floating plate 22, and it can also slide relative to the second mounting position 222 in the second direction. This allows the rotation of the floating plate 22 to better adapt to the natural bending shape of the screen. Therefore, when the display module or electronic device using this hinge is in the folded or unfolded state, the floating plate 22 and the screen can be completely fitted together, resulting in a high degree of fit and good flatness between the hinge and the screen. In addition, the hinge outline after folding is roughly teardrop-shaped, which can effectively support and protect the screen.

[0048] In some embodiments, such as Figure 1 and Figure 4 As shown, the rotating assembly 21 includes a first rod 211, a second rod 212, and a connector 215. The first rod 211 and the second rod 212 are arranged side by side on the base 1 and are rotatable relative to the base 1. The connector 215 is slidable relative to the first rod 211. It is understood that one end of the first rod 211 is aligned with the pivot axis of the base 1 in the same direction as the first direction, the width of the connector 215 extends substantially along the second direction, and the first rod 211 slides relative to the first rod 211 along the width direction of the connector 215. The connector 215 is pivotally connected to the first mounting position 221, thereby allowing the connector 215 to rotate relative to the float 22. One end of the second rod 212 is pivotally connected to the base 1, and the other end of the second rod 212 is pivotally connected to the second mounting position 222 and is slidable relative to the second mounting position 222. By configuring the rotating assembly 21 with the above structure, the hinge of the embodiments of this disclosure can achieve a simple and reasonable hinge structure with fewer parts and lower production and manufacturing costs.

[0049] Optionally, such as Figure 1 and Figure 4 As shown, the rotating assembly 21 also includes a third rod 213, one end of which is pivotally connected to the connector 215, and the other end of which is pivotally connected to the second rod 212. The hinge in this embodiment, by providing the third rod 213, improves the linkage between the second rod 212 and the connector 215 during rotation. Furthermore, when the hinge folds or unfolds, the rotation trajectory of the floating plate 22 better matches the bending trajectory of the screen, thus improving the screen's folding effect.

[0050] like Figure 4 As shown, the connector 215 has a first notch 2153, and a first pivot hole 2154 is provided on one side of the first notch 2153 along a first direction. One end of the third rod 213 has a second pivot hole 2131, and one end of the third rod 213 is located in the first notch 2153. A first pivot member (not shown) passes through the first pivot hole 2154 and the second pivot hole 2131, so that the first notch 2153 and one end of the third rod 213 can be pivotally connected. For example, the first pivot member can be a pin. The first pivot hole 2154 passes through the opposite sides of the first notch 2153. The first pivot member is detachably installed in the first pivot hole 2154 and pivotally connected to the second pivot hole 2131. The hinge of the embodiment of this disclosure can make the hinge structure more compact and the layout design more reasonable by fitting one end of the third rod 213 into the first notch 2153.

[0051] Optionally, such as Figure 2 and Figure 4 As shown, a first clearance groove 2155 is provided near the first notch 2153. The first clearance groove 2155 is used to avoid the second mounting position 222 and the second rod 212. By providing the first clearance groove 2155, the embodiments of this disclosure can avoid interference problems when the float 22 and the second rod 212 rotate relative to the connecting member 215, thereby making the hinge rotation smoother and more flexible, and making the hinge structure more compact and the layout design more reasonable.

[0052] Optionally, the first pivot hole 2154 is connected to one side of the connector 215 along the first direction. It is understood that when installing the first pivot, one end of the first pivot can be inserted into the first pivot hole 2154 from one side of the connector 215, which facilitates the assembly of the hinge and the manufacturing process.

[0053] Optionally, such as Figure 1 and Figure 4As shown, the rotating assembly 21 also includes a fourth rod 214, one end of which is pivotally connected to the first rod 211, and the other end of which is pivotally connected to the second rod 212. The hinge in this embodiment, by providing the fourth rod 214, improves the linkage between the first rod 211 and the second rod 212 during rotation, and when the hinge folds or unfolds, the rotation trajectory of the floating plate 22 better matches the bending trajectory of the screen, thus improving the screen's folding effect.

[0054] Optionally, such as Figure 2 and Figure 4 As shown, the pivot axes of the fourth rod 214 and the third rod 213, and the pivot axes of the third rod 213 and the second rod 212, are located on the same axis and parallel to the first direction. For example, the second rod 212, the third rod 213, and the fourth rod 214 can be connected in series through the same pin, so that the second rod 212, the third rod 213, and the fourth rod 214 can rotate around the same axis, thereby further improving the linkage of the hinge and effectively utilizing the installation space between the first rod 211 and the second rod 212, resulting in a smaller hinge thickness, which is conducive to achieving a slim and lightweight design of the whole machine and improving the user experience.

[0055] Optionally, such as Figure 2 and Figure 4 As shown, the first rod 211, the fourth rod 214, the third rod 213, and the second rod 212 are arranged side by side along the first direction. It can be understood that the first rod 211, the fourth rod 214, the third rod 213, and the second rod 212 are arranged sequentially along the first direction. Alternatively, the third rod 213 can be located on one side of the first rod 211 or the second rod 212, or between the first rod 211 and the second rod 212. The hinge of the embodiments of this disclosure can adjust the relative positional relationship of the first rod 211, the second rod 212, the third rod 213, and the fourth rod 214 according to actual needs, making the hinge more applicable and providing better support.

[0056] Optionally, such as Figures 2 to 4As shown, one of the connector 215 and the first mounting position 221 is provided with a first sliding groove 2151, and the other is provided with a first sliding rail 2211. For example, the first sliding groove 2151 is provided on the connector 215, and the first sliding rail 2211 is provided on the first mounting position 221. The first sliding rail 2211 is slidably engaged with the first sliding groove 2151, the first sliding groove 2151 extends along a first arc, the axis of the first arc is in the same direction as the first direction, and the first sliding rail 2211 is slidably engaged with the first sliding groove 2151 along the first arc, so that the connector 215 can rotate relative to the float 22. It can be understood that when the hinge is folded, the connector 215 and the float 22 rotate relative to each other so that the first sliding rail 2211 slides into the first sliding groove 2151 along the first arc. When the hinge unfolds, the connector 215 rotates relative to the floating plate 22, causing a portion of the first slide rail 2211 to gradually slide out along the first arc into the first slide groove 2151. This ensures a reasonable connection structure between the connector 215 and the floating plate 22, resulting in high reliability during connection. Furthermore, the arrangement of the first slide rail 2211 and the first slide groove 2151 eliminates the need for a front opening in the floating plate 22, improving its support for the screen.

[0057] Optionally, such as Figures 2 to 4 As shown, one of the connector 215 and the first rod 211 is provided with a second sliding groove 2152, and the other is provided with a second sliding rail 2111. For example, the second sliding groove 2152 is provided on the connector 215, and the second sliding rail 2111 is provided on the first rod 211. It can be understood that the width of the connector 215 extends substantially along the second direction, and the second sliding rail 2111 extends along the width direction of the connector 215 and slides in cooperation with the second sliding groove 2152. The hinge of the embodiment of this disclosure, by providing the second sliding rail 2111 and the second sliding groove 2152, can make the connection structure of the connector 215 and the first rod 211 more stable, and can also simplify the structural design, facilitate processing and manufacturing, and reduce production costs.

[0058] In some embodiments, such as Figures 2 to 4 As shown, one of the second rod 212 and the second mounting position 222 is provided with a third sliding hole 2221, and the other is provided with a third slide rail 2121. For example, the third slide rail 2121 is located on the side of the second rod 212 adjacent to the float 22 and extends along the first direction. The third sliding hole 2221 is formed on the second mounting position 222, and the axial direction of the third sliding hole 2221 is parallel to the first direction. The third slide rail 2121 and the third sliding hole 2221 are clearance-fitted, so that the third slide rail 2121 can slide relative to the third sliding hole 2221 along the second direction. The hinge of the embodiment of this disclosure, by providing the third slide rail 2121 and the third sliding hole 2221, can make the connection structure between the second rod 212 and the float 22 more stable, and can also simplify the structural design, facilitate processing and manufacturing, and reduce production costs.

[0059] Specifically, such as Figure 2 and Figure 4 As shown, the float 22 includes a float body 223, a first slide rail 2211, and a protrusion 224. The first slide rail 221 is located on the side of the float body 223 away from the base 1, and the protrusion 224 is located on the side of the float body 223 adjacent to the base 1. The first slide rail 2211 forms a first mounting position 221, and the protrusion 224 is provided with a third sliding hole 2221, which forms a second mounting position 222. Furthermore, the float body 223 is provided with a second clearance groove 2231 arranged parallel to the protrusion 224. The second clearance groove 2231 is used to avoid the second rod 212, the third rod 213, and the fourth rod 214. It can be understood that the second clearance groove 2231 can avoid the interference problem when the second rod 212, the third rod 213, and the fourth rod 214 rotate relative to the float 22, thereby making the hinge rotation smoother and more flexible, and making the hinge structure more compact and the layout design more reasonable.

[0060] In some embodiments, such as Figure 4 As shown, the rotating assembly 21 also includes a gear transmission pair, on which a first meshing tooth 231 is provided, and a second meshing tooth 2112 is provided on the first rod 211. The first meshing tooth 231 meshes with the second meshing tooth 2112 to drive the first rod 211 to rotate relative to the base 1. Since the hinge can drive the first rod 211 to swing through the gear transmission pair, the rotating assembly 21 can be made more stable when rotating and has higher reliability.

[0061] Optionally, such as Figure 4 As shown, the gear transmission pair includes a gear shaft 23, with a first meshing tooth 231 disposed on the gear shaft 23, and the gear shaft 23 is pivotally connected to the base 1. Optionally, the gear transmission pair includes a gear shaft 23 and a transmission gear (not shown), with the gear shaft 23 meshing with the second meshing tooth 2112 of the first rod 211 via the transmission gear. For example, there can be one or more transmission gears, and multiple transmission gears mesh with each other for transmission.

[0062] Optionally, such as Figure 4 As shown, the base 1 has a second notch 121. A third pivot hole 13 and a fourth pivot hole 14 are provided on one side of the second notch 121 along the first direction. One end of the first rod 211 is pivotally engaged with the third pivot hole 13, and the end of the gear shaft 23 is pivotally engaged with the fourth pivot hole 14. It can be understood that the third pivot hole 13 and the fourth pivot hole 14 can be arranged side-by-side, with one end of the first rod 211 detachably connected to the third pivot hole 13 and the end of the gear shaft 23 detachably connected to the fourth pivot hole 14. This makes the hinge connection structure more stable and facilitates production and assembly.

[0063] Optionally, such as Figure 4 As shown, the base 1 is provided with two first mounting portions 12 arranged at intervals along the first direction. For example, the first mounting portion 12 can be a protrusion structure. A second notch 121 is defined between the two first mounting portions 12. A third pivot hole 13 and a fourth pivot hole 14 are provided on the first mounting portion 12, thereby making the structure of the base 1 more reasonable, with higher structural strength, and easier to process and manufacture.

[0064] In some embodiments, such as Figures 2 to 4 As shown, there are two sets of rotating components 2, which are pivotally connected to both sides of the base 1. It can be understood that the two rotating components 2 can be unfolded and closed with the base 1 as the center. In the unfolded state, the two rotating components 2 and the base 1 between them form a plane. In the closed state, since the rotating components 2 can also rotate inside, they can be completely closed, and after closing, they present a teardrop-shaped cross section.

[0065] Among them, such as Figures 2 to 4 As shown, the base 1 can be columnar, plate-shaped, or other shapes. The base 1 and the rotating component 2 can be rotatably connected by a pivot, a hinge, or a sliding along an arc-shaped sliding path; this application does not limit the specific type of connection.

[0066] Specifically, such as Figure 2 and Figure 4 As shown, each rotating component 2's rotating assembly 21 includes a gear shaft 23. Two gear shafts 23 are arranged on both sides of the base 1 and are rotatable relative to the base 1. The gear shafts 23 are provided with first meshing teeth 231, and the first rod 211 is provided with second meshing teeth 2112. The first meshing teeth 231 and the second meshing teeth 2112 mesh, and the first meshing teeth 231 of the two gear shafts 23 mesh with each other. It can be understood that one of the two gear shafts 23 is connected to a drive motor (not shown). Since the first meshing teeth 231 of the two gear shafts 23 mesh with each other, the drive motor can drive the gear shaft 23 to rotate, so that the two gear shafts 23 rotate synchronously, thereby driving the rotating assemblies 21 on both sides of the base 1 to open or close synchronously.

[0067] In some embodiments, such as Figures 2 to 4 As shown, the hinge in the embodiment of this disclosure also includes a cover 3, which is disposed at the lower end of the base 1. For example, the cover 3 is provided with a clearance structure corresponding to the mounting structure on the base 1, so as to cover the pivot position of the base 1 and the rotating component 21, thereby improving the reliability of the hinge during use.

[0068] Optionally, such as Figure 4As shown, one of the second rod 212 and the base 1 has an arc-shaped recess 2122, and the other has an arc-shaped shaft 11. The arc-shaped recess 2122 and the arc-shaped shaft 11 are pivotally connected. For example, the base 1 includes a base body 15 and arc-shaped shafts 11. There are two arc-shaped shafts 11, which are arranged side by side and spaced apart along the width direction of the base 1. The base body 15 and the arc-shaped shafts 11 are integrally formed. The second rod 212 has an arc-shaped recess 2122 with an arc-shaped recessed surface. The arc-shaped recessed surface cooperates with the arc-shaped shaft 11 and can rotate relative to the arc-shaped shaft. Therefore, the hinge of the embodiment of this disclosure, by setting the arc-shaped recess 2122 and the arc-shaped shaft 11, can reduce the number of parts during hinge assembly, and has a reasonable structural design and good practicality.

[0069] Specifically, such as Figure 3 and Figure 4 As shown, the cover 3 is provided with a third clearance groove 31. The third clearance groove 31 is located on the side of the cover 3 adjacent to the base 1. There are two third clearance grooves 31, which are arranged at intervals and correspond one-to-one with the two arc-shaped shaft portions 11. An arc-shaped receiving cavity 32 is defined between the third clearance groove 31 and the arc-shaped shaft portion 11. The arc-shaped recess 2122 can rotate in the arc-shaped receiving cavity 32, which makes the second rod 212 rotate more smoothly relative to the base 1, and reduces the number of parts used. The structure is compact and the layout is reasonable.

[0070] A display module according to another embodiment of this disclosure includes: a screen and a hinge, wherein the hinge is the same as that of the embodiment of this disclosure. A floating plate 22 supports the screen. It is understood that the screen is disposed on the upper end of the floating plate 22 and the base 1 and is in contact with the floating plate 22 and the base 1. In other words, the back of the screen is connected to the inner side of the hinge, and the screen can be folded and unfolded as the hinge opens and closes.

[0071] An electronic device according to another embodiment of the present disclosure includes a hinge according to an embodiment of the present disclosure or a display module according to an embodiment of the present disclosure.

[0072] According to the embodiments of the present disclosure, the display module and the electronic device having the display module can support the screen through the floating plate 22. Since the other end of the rotating component 21 is pivotally connected to the first mounting position 221 and the second mounting position 222, and the rotating component 21 is slidable relative to the second mounting position 222 in the second direction, the screen can be better supported by the floating plate 22 when the display module is folded or unfolded, so that the floating plate 22 has a high degree of fit with the screen and good flatness.

[0073] Furthermore, since the hinge rotation component 21 of the embodiments of this disclosure includes multiple linkages, the hinge exhibits better stability during use, a reliable connection structure, fewer components, and lower production and manufacturing costs. Moreover, when the display module and electronic device with this hinge are in a folded state, the hinge outline is generally teardrop-shaped, effectively supporting and protecting the screen, and the overall thickness is relatively small, which is beneficial for achieving a thinner and lighter design of electronic devices and improving the user experience.
