[0061] Figure 1 It is a structural diagram of an electronic device in the related technology. Figure 1 As shown, the electronic device includes a hinge body 10, two folding components 20, two middle frames 40 and a flexible screen 50. The two folding components 20 are respectively located on opposite sides of the hinge body 10 and are connected to the hinge body 10. The folding component 20 can rotate around the hinge body 10. The two middle frames 40 are respectively connected to the two folding components 20. The flexible screen 50 is connected to the two middle frames 40. Since the folding components 20 are connected to the middle frames 40, during the folding process of the electronic device, the two middle frames 40 will rotate around the hinge body 10 under the action of the folding components 20, and the flexible screen 50 will also bend under the action of the middle frame 50.

[0062] Figure 2 FIG. 2 is a schematic diagram of a hinge structure in the related art. The dotted line in the figure represents the pin hole 227, which is located on the middle frame connecting member 22. Figure 2 As shown, the folding assembly 20 includes a support member 21, a middle frame connecting member 22, a first swing arm 23 and a sliding member 24. The middle frame connecting member 22, the first swing arm 23 and the sliding member 24 are located on the same side of the support member 21, and the support member 21 is pivotally connected to the middle frame connecting member 22. The first swing arm 23 is pivotally connected to the hinge body 10, and the first swing arm 23 is slidably connected to the middle frame connecting member 22. The first swing arm 23 is slidably connected to the sliding member 24 through a pin shaft. The sliding member 24 has a closed slide groove. When assembling the folding assembly, it is necessary to push the pin shaft into the slide groove on the sliding member 24 through the pin shaft hole 227 on the middle frame connecting member 22, and then fix the pin shaft to the first swing arm 23. This hinge not only needs to set the pin shaft hole 227, but also the installation of the pin shaft is more troublesome, which affects the assembly efficiency.

[0063] Figure 3 FIG. 1 is a schematic diagram of an assembly of a hinge provided by an embodiment of the present disclosure. Figure 3 As shown, the hinge includes a hinge body 10 and a folding assembly 20 , and the folding assembly 20 is movably connected to two opposite sides of the hinge body 10 . Figure 3 As an example, only the folding assembly 20 located at one side of the hinge body 10 is shown. The folding assembly 20 includes a first swing arm 23, a sliding member 24 and a guide member 25, and the first swing arm 23 is movably connected to the hinge body 10.

[0064] Figure 4 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Figure 4 As shown, the side wall of the sliding member 24 has a slide groove 241, and the end of the slide groove 241 close to the hinge body 10 has a notch 242. The guide member 25 is connected to the first swing arm 23, and the guide member 25 can enter or exit the slide groove 241 through the notch 242. The guide member 25 can be a pin or a protrusion.

[0065] By setting a notch at one end of the slide groove close to the hinge body, the guide member connected to the first swing arm can enter the slide groove through the notch during assembly, and can also exit the slide groove through the notch during disassembly, which facilitates the assembly of the hinge and does not require a guide member hole to be set on the middle frame connecting member, which is beneficial to improving production efficiency.

[0066] like Figure 3 As shown, the folding assembly 20 further includes a support member 21 and a middle frame connecting member 22. The sliding member 24 is connected to the support member 21, the middle frame connecting member 22, the first swing arm 23 and the sliding member 24 are located on the same surface of the support member 21, the middle frame connecting member 22 is pivoted to the support member 21, the first swing arm 23 is slidably connected to the middle frame connecting member 22, and the first swing arm 23 is pivoted to the hinge body 10. When the folding assembly 20 rotates around the hinge body 10, the first swing arm 23 rotates around the hinge body 10, the middle frame connecting member 22 slides relative to the first swing arm 23, and the support member 21 rotates relative to the middle frame connecting member 22.

[0067] like Figure 4 As shown, the slide groove 241 is in an arc shape. When the folding assembly 20 rotates around the hinge body 10, the middle frame connecting member 22 slides relative to the first swing arm 23, and the sliding member 24 also slides relative to the first swing arm 23. At this time, the guide member 25 moves along the arc track of the slide groove 241, and the sliding member 24 and the support member 21 rotate relative to the middle frame connecting member 22 under the action of the guide member 25.

[0068] like Figure 4As shown, the sliding member 24 includes a mounting portion 243, a limiting portion 244 and a first connecting portion 245. The mounting portion 243 is connected to the support member 21, and the limiting portion 244 is located on a side of the mounting portion 243 away from the support member 21. The first connecting portion 245 is located on a side of the mounting portion 243 away from the hinge body 10, and the first connecting portion 245 is connected to the mounting portion 243 and the limiting portion 244 respectively, and the mounting portion 243, the limiting portion 244 and the first connecting portion 245 surround the sliding groove 241.

[0069] The mounting portion 243, the limiting portion 244 and the first connecting portion 245 form a slide groove 241 to limit the range of motion of the guide member 25. At one end of the slide groove 241 close to the hinge body 10, the mounting portion 243 and the limiting portion 244 are spaced apart from each other. When the first swing arm 23 and the sliding member 24 are connected, the guide member 25 can slide directly from the notch 242 into between the mounting portion 243 and the limiting portion 244. The structures of the first swing arm 23 and the guide member 25 can be the same as those in the related art, and there is no need to change the structures of the first swing arm 23 and the guide member 25. While facilitating the assembly of the hinge, the impact on the manufacturing process is small, which is conducive to saving costs.

[0070] like Figure 4 As shown, the first swing arm 23 includes a first slide rail 231, a second slide rail 232 and a rotating portion 233. The first slide rail 231 and the second slide rail 232 are located on the same side of the rotating portion 233, and the first slide rail 231 and the second slide rail 232 are respectively connected to the rotating portion 233. The rotating portion 233 is hinged to the hinge body 10. The first slide rail 231, the second slide rail 232 and the rotating portion 233 form a mounting groove 234. The guide member 25 and the sliding member 24 are both located in the mounting groove 234. The mounting groove 234 can cooperate with the sliding member 24 to limit the movement of the sliding member 24 in the mounting groove 234, so that the relative movement of the sliding member 24 and the first swing arm 23 is smoother.

[0071] The two ends of the guide member 25 are respectively connected to the first slide rail 231 and the second slide rail 232. Since the slide member 24 is provided with a notch 242, the guide member 25 can be firstly installed and fixed with the first swing arm 23, and then the guide member 25 can be slid from the notch 242 of the slide member 24 into the slide groove 241 to realize the sliding connection between the first swing arm 23 and the slide member 24.

[0072] Figure 5 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Figure 5 As shown, the guide member 25 is located in the mounting groove 234, and the guide member 25 is connected to the first slide rail 231. There is a gap between the guide member 25 and the second slide rail 232.

[0073] In other examples, the guide member 25 may also be connected to the second slide rail 232 , with a gap between the guide member 25 and the first slide rail 231 .

[0074] Figure 6 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Figure 6 As shown, the folding assembly 20 includes two guide members 25, one of which is connected to the first slide rail 231, and the other is connected to the second slide rail 232. The two guide members 25 are coaxial, and there is a gap between the two guide members 25. The two guide members 25 cooperate with the sliding member 24, and the relative movement between the first swing arm 23 and the sliding member 24 is more stable.

[0075] Figure 7 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Figure 7 As shown, the sliding member 24 includes a mounting portion 243, a limiting portion 244, a first connecting portion 245 and a second connecting portion 246. The mounting portion 243 is connected to the support member 21, and the limiting portion 244 is located on a side of the mounting portion 243 away from the support member 21. The first connecting portion 245 is located on a side of the mounting portion 243 away from the hinge body 10, and the first connecting portion 245 is connected to the mounting portion 243 and the limiting portion 244 respectively. The second connecting portion 246 is located on a side of the mounting portion 243 close to the hinge body 10, and the second connecting portion 246 is connected to the mounting portion 243 and the limiting portion 244 respectively. The mounting portion 243, the limiting portion 244, the first connecting portion 245 and the second connecting portion 246 form a slide groove 241. The width h1 of the second connecting portion 246 in the depth direction of the slide groove 241 is less than the depth d of the slide groove 241. By connecting the mounting portion 243 and the limiting portion 244 via the second connecting portion 246 , the strength of the sliding member 24 can be improved, deformation of the sliding member 24 can be avoided, and the stability of the hinge can be improved.

[0076] like Figure 7 As shown, one end of the guide member 25 is connected to the first slide rail 231, and the guide member 25 is located at one side of the second connection portion 246 in the depth direction of the slide groove 241. One end of the guide member 25 is connected to the first slide rail 231, and during assembly, the guide member 25 can slide into the slide groove 241 from the side of the second connection portion 246 close to the first slide rail 231.

[0077] In other examples, the guide member 25 may also be connected to the second slide rail 232 , with a gap between the guide member 25 and the first slide rail 231 .

[0078] Figure 8 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Figure 8As shown, the folding assembly 20 includes two guide members 25, one of the two guide members 25 is connected to the first slide rail 231, and the other is connected to the second slide rail 232. The two guide members 25 are coaxial, and there is a gap between the two guide members 25. By providing two guide members 25, during assembly, the two guide members 25 slide into the slide groove 241 from both sides of the second connecting portion 246. The two guide members 25 jointly bear the interaction force between the first swing arm 23 and the sliding member 24, and the force on each guide member 25 is small, and the guide member 25 is not easy to deform or break, thereby ensuring the stability of the overall structure.

[0079] Fig. 9 yes Figure 8 A top view of the Fig. 9 As shown, the gap s between the two guide members 25 is not less than the width h1 of the second connecting portion 246 along the depth direction of the slide groove 241 and is less than the depth d of the slide groove 241 so that the first swing arm 23 and the sliding member 24 can be assembled normally.

[0080] Fig.10 Schematic diagram of a structure of a sliding member provided by an embodiment of the present disclosure. Fig.10 As shown, the sliding member 24 includes a mounting portion 243, a limiting portion 244, a first connecting portion 245, a second connecting portion 246 and an isolating portion 247. The mounting portion 243 is connected to the support member 21, and the limiting portion 244 is located on a side of the mounting portion 243 away from the support member 21. The first connecting portion 245 is located on a side of the mounting portion 243 away from the hinge body 10, and the first connecting portion 245 is connected to the mounting portion 243 and the limiting portion 244 respectively. The second connecting portion 246 is located on a side of the mounting portion 243 close to the hinge body 10, and the second connecting portion 246 is connected to the mounting portion 243 and the limiting portion 244 respectively. The mounting portion 243, the limiting portion 244, the first connecting portion 245 and the second connecting portion 246 surround the slide groove 241. The isolation portion 247 is located in the slide groove 241 and connected to the inner wall of the slide groove 241. The width h2 of the isolation portion 247 in the depth direction of the slide groove 241 is smaller than the depth d of the slide groove 241. Adding the isolation portion 247 in the slide groove 241 can further improve the strength of the sliding member 24, prevent the sliding member 24 from deforming, and help improve the stability of the hinge.

[0081] like Fig.10 As shown, one end of the guide member 25 is connected to the first slide rail 231, and in the depth direction of the slide groove 241, the guide member 25 is located on one side of the isolation portion 247. During assembly, the guide member 25 slides into the slide groove 241 from the side of the isolation portion 247 close to the first slide rail 231.

[0082] In other examples, the guide member 25 may also be connected to the second slide rail 232 , with a gap between the guide member 25 and the first slide rail 231 .

[0083] Fig.11 FIG. 1 is a schematic diagram of an assembly of a first swing arm and a sliding member provided by an embodiment of the present disclosure. Fig.11 As shown, the folding assembly 20 includes two guide members 25, one of the two guide members 25 is connected to the first slide rail 231, and the other is connected to the second slide rail 232. The two guide members 25 are coaxial, and there is a gap between the two guide members 25. By providing two guide members 25, during assembly, the two guide members 25 slide into the slide groove 241 from both sides of the second connecting portion 246. The two guide members 25 jointly bear the interaction force between the first swing arm 23 and the sliding member 24, and the force on each guide member 25 is small, and the guide member 25 is not easy to deform or break, thereby ensuring the stability of the overall structure.

When the first swing arm 23 and the sliding member 24 are assembled, the guide member 25 slides from the notch 242 into the slide groove 241. As an example, Fig.12 The structure of the sliding member 24 shown in Fig.10 The structure of the sliding member 24 is the same as in other examples. Fig.12 The structure of the sliding member 24 shown in FIG. Figure 4 or Figure 7 The structure of the sliding member 24 shown in FIG. 1 is the same.

[0085] Optionally, the guide member 25 and the first swing arm 23 can be an integral structure, that is, the guide member 25 and the first swing arm 23 are integrally formed by a process such as injection molding. Since a notch 242 is provided on the sliding member 24, the guide member 25 can slide from the notch 242 into the slide groove 241. Therefore, even if the guide member 25 and the first swing arm 23 are connected as a whole before assembly, the assembly is not affected. The guide member 25 and the first swing arm 23 are integrally formed, which makes the production more convenient. In addition, the guide member 25 and the first swing arm 23 can also be independently provided, and the guide member 25 and the first swing arm 23 are connected together by a connecting structure.
