[0060] For a more complete and detailed description of this disclosure, reference is made to the accompanying drawings and various embodiments described below. The elements in the drawings are not drawn to scale and are provided solely for the purpose of illustrating this disclosure. Numerous practical details are described below to provide a thorough understanding of this disclosure. However, those skilled in the relevant art will appreciate that this disclosure may be practiced without one or more of these practical details, and therefore, these details should not be construed as limiting this disclosure.

[0061] Please refer to Figure 1 and Figure 2 The foldable electronic device 100 includes two frames 101 and 102, two flexible members 111 and 112, and at least one hinge 120 (also known as a rotating shaft). The two frames 101 and 102 are arranged side by side. The two flexible members 111 and 112 are disposed on the frames 101 and 102 on opposite sides of the frames 101 and 102. The hinge 120 connects the two frames 101 and 102 and is located between the two flexible members 111 and 112. The frames 101 and 102 can be flipped relative to each other via the hinge 120, thereby expanding or folding the flexible members 111 and 112.

[0062] like Figure 1 and Figure 2As shown, in some embodiments, the foldable electronic device 100 includes two hinge devices 120 connected by a rod 103. In some embodiments, one of the flexible members 111 and 112 includes a flexible display panel (e.g., a flexible organic light-emitting diode display panel), while the other may include a flexible display panel or a flexible cover. In some embodiments, the flexible members 111 and 112 are fixed to the frames 101 and 102 using fasteners such as screws or adhesive.

[0063] like Figure 1 and Figure 2 As shown, in some embodiments, the flexible member 111 includes a first area A1 and a second area A2. The first area A1 and the second area A2 are connected to the two frames 101 and 102, respectively, and the first area A1 is configured to bend relative to the second area A2. The foldable electronic device 100 can be in an unfolded state or a folded state. When the foldable electronic device 100 is in the unfolded state, the angle between the first area A1 and the second area A2 of the flexible member 111 is substantially 180 degrees. When the foldable electronic device 100 is in the folded state, the first area A1 and the second area A2 of the flexible member 111 are stacked.

[0064] In some embodiments, the flexible member 112 also includes a first region B1 and a second region B2 that can be bent relative to each other. The configurations thereof are similar to the first region A1 and the second region A2 of the flexible member 111 . Please refer to the description in the previous paragraph and will not be repeated here.

[0065] Please refer to Figure 3 and Figure 4 The hinge device 120 can adjust the distance between the two frames 101 and 102 as the frames 101 and 102 are flipped and changed in angle, thereby facilitating the expansion and folding of the flexible members 111 and 112. Specifically, the hinge device 120 includes a shaft 130, a rotating member 140A, a sliding member 150A, and a chain 160A. The rotating member 140A is rotatably connected to the shaft 130. The sliding member 150A is slidably disposed on the rotating member 140A and is configured to rotate around the shaft 130 along with the rotating member 140A. The sliding member 150A is fixedly connected to the frame 101, so that the frame 101 moves with the sliding member 150A. The chain 160A is connected to the sliding member 150A and is a retractable structure that can pull the sliding member 150A to slide on the rotating member 140A as the frames 101 and 102 are flipped and changed in angle.

[0066] like Figure 3 and Figure 4As shown, in some embodiments, the rotating member 140A has a groove D for accommodating the sliding member 150A. In some embodiments, the rotating member 140A has a slide groove 142A formed on at least one side wall of the groove D. The sliding member 150A includes a slide rail 152A that is slidably connected to the slide groove 142A.

[0067] like Figure 3 and Figure 4 As shown, in some embodiments, the rotating member 140A has an end surface 144A, which is located on the side of the rotating member 140A away from the shaft 130. The sliding member 150A has an end surface 154A, which is located on the side of the sliding member 150A away from the shaft 130. The hinge device 120 can be in an unfolded state or a folded state. When the hinge device 120 is in the unfolded state, the sliding member 150A partially protrudes from the end of the rotating member 140A. In other words, the distance between the end surface 154A of the sliding member 150A and the shaft 130 is greater than the distance between the end surface 144A of the rotating member 140A and the shaft 130. When the hinge device 120 is in the folded state, the sliding member 150A is retracted into the rotating member 140A. In other words, the end surface 154A of the sliding member 150A is aligned with the end surface 144A of the rotating member 140A.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments, the hinge device 120 includes another set of rotating components 140B, sliding components 150B, and chains 160B, wherein the sliding components 150B are fixedly connected to the frame 102. When the hinge device 120 is in the deployed state, the two rotating components 140A and 140B are located on opposite sides of the shaft 130. The linkage between the rotating components 140B, sliding components 150B, and chain 160B is similar to that between the rotating components 140A, sliding components 150A, and chain 160A. Please refer to the relevant description above and will not be repeated here.

[0069] like Figure 3 and Figure 4 As shown, in some embodiments, chains 160A and 160B are disposed through the shaft 130. In some embodiments, the chain 160A is connected to the sliding member 150A, and the chain 160B is connected to the sliding member 150B.

[0070] Please refer to Figure 4 and Figure 5Chains 160A and 160B include a plurality of chain monomers 162, with adjacent chain monomers 162 movably connected to each other. Specifically, chain 160B includes adjacent first chain monomers 162A and second chain monomers 162B. First chain monomer 162A includes a first pivot portion 164A, and second chain monomer 162B includes a second pivot portion 164B. Second pivot portion 164B is movably connected to first pivot portion 164A. In this embodiment, second pivot portion 164B is movably mounted on first pivot portion 164A (i.e., second pivot portion 164B is disposed around first pivot portion 164A).

[0071] like Figure 4 and Figure 5 As shown, in some embodiments, the second pivot portion 164B has an opening, and the first pivot portion 164A includes a column that is rotatably and slidably located within the opening. In some embodiments, the maximum width of the opening is greater than the maximum width of the column, allowing the column to slide within the opening, thereby changing the relative position of the first chain monomer 162A and the second chain monomer 162B.

[0072] like Figure 4 and Figure 5 As shown, the hinge device 120 further includes at least one elastic member E (represented by dots in the figure), which is disposed within at least one chain unit 162. The presence of the elastic member E prevents particles or moisture from entering the chains 160A and 160B, thereby extending the life of the hinge device 120. Furthermore, the elastic member E deforms as the frames 101 and 102 rotate relative to each other, changing the distance between adjacent chain units 162. This allows the chains 160A and 160B to expand and contract to adjust the distance between the frames 101 and 102, thereby facilitating the expansion and folding of the flexible members 111 and 112.

[0073] like Figure 4 and Figure 5 As shown, in some embodiments, any elastic body E is configured to contact adjacent first and second chain monomers 162A, 162B. In some embodiments, the hinge device 120 includes multiple elastic bodies E, each of which is disposed between the first pivot portion 164A and the second pivot portion 164B of a pair of adjacent chain monomers 162. Any elastic body E only contacts at most two chain monomers 162 simultaneously, and any two elastic bodies E are separated and unconnected. In some embodiments, the elastic body E fills the opening of the second pivot portion 164B and covers the column of the first pivot portion 164A.

[0074] In some embodiments, elastomer E comprises one or more organic polymers. Elastomer E comprises an organic polymer with a backbone composed of carbon-carbon (CC) linkages or siloxane (Si-O-Si). In some embodiments, the functional groups bonded to the silicon or carbon atoms comprise methyl (CH3) or fluorine-based molecular groups, whose hydrophobic properties prevent moisture from entering the chains 160A and 160B.

[0075] Please refer to Figure 6 Different from the above-mentioned embodiment, the hinge device 420 of this embodiment is filled with two or more different elastic bodies in the chain 460 to control the movement mode of the chain 460 and the curvature of the bending part of the chain 460 .

[0076] like Figure 6 As shown, in some embodiments, the chain monomers of the chain 460 are divided into at least a first group and a second group. When the foldable electronic device or hinge device 420 is in the folded state, the chain monomers 462A belonging to the first group are disposed around the shaft 130. The second group is adjacent to the first group. The hinge device 420 includes a first elastomer E1 and a second elastomer E2, wherein the first elastomer E1 is disposed on the chain monomers 462A belonging to the first group, and the second elastomer E2 is disposed on the chain monomers 462B belonging to the second group. The elastic modulus of the first elastomer E1 is smaller than the elastic modulus of the second elastomer E2 (for example, the first elastomer E1 and the second elastomer E2 are composed of different materials). In this embodiment, the first elastomer E1 and the second elastomer E2 are respectively disposed within the openings of the pivotal portions (used to connect adjacent chain monomers) of the chain monomers 462A and 462B.

[0077] like Figure 6 As shown, the first group of chain monomers 462A form the curved section of the chain 460 around the shaft 130. A first elastic body E1 with a relatively low elastic modulus is positioned on the first group of chain monomers 462A. This allows the curved section of the chain 460 to smoothly extend and form an arc structure when the hinge device 420 is folded. A second elastic body E2 with a relatively high elastic modulus is positioned on the second group of chain monomers 462B adjacent to the first group. This second group acts like a "fulcrum," helping to transfer stress to the first group of chain monomers 462A when the hinge device 420 is folded, thereby facilitating the extension and bending of the section of the chain 460 formed by the first group of chain monomers 462A.

[0078] like Figure 6As shown, in some embodiments, the chain monomers of chain 460 are further divided into a third group, with the second group located between the first and third groups. The hinge device 420 further includes a third elastomer E3, which is disposed within the chain monomers 462C belonging to the third group. The elastic modulus of the third elastomer E3 is less than that of the second elastomer E2 and greater than that of the first elastomer E1 (for example, the third elastomer E3 is made of a different material than the first elastomer E1 / second elastomer E2). In some embodiments, the chain monomers 462C belonging to the third group are arranged in a straight line on one side of the rotating component 140B.

[0079] The chain monomers 462C of the third group can serve as extended sections of the chain 460 , and can increase the extension of the chain 460 when the hinge device 420 is opened or closed, depending on practical needs.

[0080] In some embodiments, the Young's modulus of the first elastic body E1 is less than 50 N / mm 2 , and the elongation of the first elastic body E1 is less than 1000%, and the Young's modulus of the second elastic body E2 is greater than 150N / mm 2 , and the elongation of the second elastic body E2 is less than 500%, and the Young's modulus of the third elastic body E3 is between 50 and 150 N / mm 2 and the elongation of the third elastic body E3 is between 1000% and 1500%.

[0081] Please refer to Figure 7 and Figure 8 This embodiment differs from the previous embodiment in the location where the elastomer E is filled. Specifically, the first chain monomer 162A has a groove S for receiving the second pivot portion 164B of the adjacent second chain monomer 162B. The elastomer E fills the groove S of the first chain monomer 162A, and the elastomer E at least partially covers the second pivot portion 164B and contacts at least one sidewall of the groove S. In some embodiments, the first pivot portion 164A includes a column connected between two opposing sidewalls of the groove S and passes through the second pivot portion 164B. The elastomer E at least partially covers the surface of the second pivot portion 164B away from the first pivot portion 164A. In some embodiments, the elastomer E may be disposed both within the groove S and in the gap between the first and second pivot portions 164A, 164B.

[0082] In some embodiments, the hinge device includes a plurality of elastic bodies E, each of which is disposed in a groove S of one of the chain monomers of the chain 160B, and any two elastic bodies E are separated and not connected to each other. In some embodiments, the plurality of chain monomers of the chain 160B can be divided into a plurality of groups, and the grooves S of the chain monomers of different groups can be filled with different elastic bodies. For example, a similar method can be adopted. Figure 6 In the manner shown, the first elastomer E1 , the second elastomer E2 or the third elastomer E3 is filled into the groove S of the chain monomer.

[0083] Please refer to Figure 9 Unlike the previous embodiment, in this embodiment, the second pivotal portion 264B of the second chain member 262B is movably inserted into the first pivotal portion 264A of the first chain member 262A. Specifically, the second pivotal portion 264B includes a protrusion structure and at least one bump structure. The protrusion structure extends into the groove S of the first chain member 262A, and the bump structure is disposed on at least one side of the protrusion structure. The first pivotal portion 264A includes an opening defined in at least one side wall of the groove S. The bump structure of the second pivotal portion 264B is rotatably and slidably positioned within the opening. The opening can be open, i.e., it can have a notch. In other embodiments, the opening can also be closed. The elastomer E at least partially covers the second pivotal portion 264B. In some embodiments, the elastomer E is disposed in the groove S and covers one end of the protrusion structure of the second pivotal portion 264B. In some embodiments, the elastomer E may contact the bump structure of the second pivotal portion 264B.

[0084] Please refer to Figure 10 , different from Figure 9 In the embodiment shown, the elastic body E of this embodiment is disposed between the first pivot portion 264A and the second pivot portion 264B. In some embodiments, the elastic body E fills the opening of the first pivot portion 264A and covers the protrusion structure of the second pivot portion 264B. In some embodiments, the elastic body E can be placed in the groove S of the first chain monomer 262A (see Figure 9 ) and the gap between the first pivoting portion 264A and the second pivoting portion 264B are both provided with an elastic body E.

[0085] Please refer to Figure 11Unlike the previous embodiment, the elastomer E in this embodiment covers at least one chain monomer 362 of the chain 360. In some embodiments, the chain 360 includes a first chain monomer 362A and a second chain monomer 362B. The first chain monomer 362A has a through-hole 366, and the second chain monomer 362B extends through the through-hole 366, so that the second chain monomer 362B interlocks with the first chain monomer 362A. The elastomer E covers the surface of the first chain monomer 362A away from the through-hole 366 and fills the through-hole 366, replenishing the space in the through-hole 366 not occupied by the adjacent chain monomer.

[0086] In some embodiments, the chain monomers 362 of the chain 360 are closed ring structures. In some embodiments, the chain monomers of the chain 360 can be divided into multiple groups, and different elastomers can be used to coat the chain monomers of different groups. For example, a similar Figure 6 In the illustrated manner, the chain 360 is segmentally coated with three different first elastomers E1, second elastomers E2, or third elastomers E3.

[0087] Please refer to Figure 12 The foldable electronic device 500 of this embodiment is Figure 1 The embodiment shown differs in that chain 560A of hinge assembly 520 is directly connected to frame 101, while chain 560B is directly connected to frame 102. Hinge assembly 520 also includes an elastic member (not shown) disposed within or covering each of chains 560A and 560B. The specific structural configuration of chains 560A and 560B and the elastic member can be similar to any of the previously described embodiments; please refer to the relevant description above.

[0088] In some embodiments, the hinge device 520 further includes brackets 570A and 570B, and the chains 560A and 560B are respectively mounted on the brackets 570A and 570B. In some embodiments, the end of the chain 560A away from the frame 101 is connected to the bracket 570B, and the end of the chain 560B away from the frame 102 is connected to the bracket 570A.

[0089] In summary, the hinge device of the foldable electronic device disclosed herein comprises a chain and an elastic body disposed within or covering the chain. This simple structure of the chain and the elastic body can guide the opening and closing of the electronic device's flexible component (display panel or cover). The elastic body also prevents particles and moisture from entering the chain, thereby extending the life of the hinge device.

[0090] Although the present disclosure has been disclosed above in the form of embodiments, it is not intended to limit the present disclosure. Anyone skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be determined by the scope defined in the appended claims.
