[0052] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0053] The following describes the principle of the hinge component for realizing screen folding in the related art. In order to make the technical solution in the related art easier to understand, the following describes the technical solution in the related art with the length direction of the support member being consistent with the front-back direction, the thickness direction being consistent with the up-down direction, and the width direction being consistent with the left-right direction, wherein the left-right direction, the up-down direction, and the front-back direction can be as follows: Figure 1 shown.

[0054] The hinge component in the related art includes a support member and a linkage assembly arranged on the support member, wherein the hinge component is used to connect the mobile phone housing and the screen (flexible screen). Specifically, multiple support members are arranged side by side in a certain order, such as from left to right or from right to left, and the multiple support members together constitute a base arranged below the screen for supporting the screen. The support member has two sides arranged relative to each other in the thickness direction. In other words, the support member has an upper surface and a lower surface arranged relative to each other in the up and down directions. The linkage assembly is arranged below the lower surface of the support member, and the screen is arranged above the upper surface of the support member. By arranging studs or holes on the leftmost and rightmost support members and connecting them to the middle frame of the mobile phone housing through screws, the hinge component is connected to the mobile phone housing and the screen, and the screen is folded by utilizing the synchronous movement and rotation of the linkage assembly.

[0055] However, the support members are linked only by linkage components. Not only does the hinge component occupy a large space, which is not conducive to the stacking of thin and light terminal devices, but the hinge component cannot effectively fit and fully support the screen, resulting in wrinkles and pulling deformation during the folding process. Therefore, how to effectively improve the technical defects of the hinge component in the related art, such as the large space occupied by the hinge component and the inability to effectively fit and fully support the screen, is a technical problem that those skilled in the art urgently need to solve.

[0056] Examples of the present invention are described in detail below. Examples of the examples are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The examples described below with reference to the accompanying drawings are illustrative and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0057] like Figures 1 to 3 As shown, an embodiment of the present invention proposes that the hinge component 100 includes a support assembly 1 and a linkage assembly 2, the support assembly 1 includes at least three support members 11, and the multiple support members 11 are arranged side by side in the length direction; and the adjacent two support members 11 are movably connected; the linkage assembly 2 is connected to the support member 11 to realize the mutual linkage of the multiple support members 11.

[0058] Specific examples Figure 1 As shown, in this embodiment, the support assembly 1 has two sides arranged oppositely in the thickness direction, that is, the support assembly 1 has an upper surface and a lower surface arranged oppositely in the upper and lower directions, wherein the linkage assembly 2 is arranged below the lower surface of the support assembly 1; the screen cover is arranged above the upper surface of the support assembly 1. In this embodiment, the left and right ends of the screen can be simultaneously bent and folded toward the side where the linkage assembly 2 is arranged, as shown in FIG. Figure 3 As shown, the arrangement of the linkage assembly 2 in this embodiment ensures that the multiple symmetrically arranged support members 11 move synchronously.

[0059] In order to make the technical solution of the present application easier to understand, the following describes the technical solution in the related art with the length direction of the support member 11 being consistent with the front-to-back direction, the thickness direction being consistent with the up-down direction, and the width direction being consistent with the left-right direction, wherein the left-right direction, the up-down direction, and the front-to-back direction can be as follows: Figure 1 and Figure 3 shown.

[0060] Specific as Figure 1 As shown, in this embodiment, multiple support members 11 are arranged side by side. This can be understood as multiple support members 11 being arranged side by side in a certain order, for example, from left to right, and each adjacent support member 11 is movably connected. For example, support member A is respectively provided with support member B and support member C on its left and right sides, and both support member B and support member C can rotate relative to support member A.

[0061] In this embodiment, the support members 11 can be further refined through the movable connection between two adjacent support members 11. That is, when supporting the same screen, compared with the prior art, this embodiment can increase the number of support members 11 and reduce the width of the support members 11 to achieve the purpose of fine division of the support area, thereby improving the overall technical defect of the large space occupied by the hinge component 100, and promoting the architectural stacking of lightweight terminal devices. At the same time, the hinge component 100 can effectively fit and fully support the screen, so as to improve the technical defects of wrinkles and pulling deformation that occur during the folding process of the screen in related technologies.

[0062] It is understood that the screen in this embodiment is a display screen of a terminal device such as a mobile phone display screen or a computer display screen, specifically a flexible screen. Those skilled in the art will understand that a flexible screen refers to a lightweight, non-fragile display that still exhibits the characteristics of a traditional flat-panel display and is manufactured on a flexible substrate that can be bent, folded, twisted, or rolled.

[0063] In some embodiments, each support member 11 is provided with at least two guide portions 102, which face opposite sides of the width of the support member 11 and are movably connected to the guide portions 102 on adjacent support members 11. The guide portions 102 are used to guide and limit the position of adjacent support members 11 during the rotation of the hinge assembly.

[0064] Specific examples Figure 1 As shown, each support member 11 is provided with at least two guide portions 102, wherein the two guide portions 102 are respectively located at the two ends of the length direction of the support member 11, that is, one guide portion 102 is located at the front end of the support member 11, and the other guide portion 102 is located at the rear end of the support member 11; and the two guide portions face the left side and the right side of the support member 11, respectively. For example, the guide portion 102 facing the left side of the support member 11 is movably connected to a guide portion 102 facing the right side of the support member 11 adjacent to the left side of the support member 11. According to this rule, multiple support members 11 are arranged side by side, and adjacent support members 11 are movably connected.

[0065] It is understandable that the guide portion 102 is provided on the support member 11 in one of the following ways: fixed, detachable, or integrally formed.

[0066] In some embodiments, the guide portion 102 includes a first guide portion 1021 and a second guide portion 1022. At least one first guide portion 1021 and at least one second guide portion 1022 are provided on a support member 11. The first guide portion 1021 and the second guide portion 1022 extend toward both sides of the width direction of the support member 11 and exceed the edges of the corresponding sides of the support member 11. The first guide portion 1021 of a support member 11 is movably connected to the second guide portion 1022 of an adjacent support member 11.

[0067] The provision of at least one first guide portion 1021 and at least one second guide portion 1022 on one of the support members 11 can be understood as including at least two solutions:

[0068] The first technical solution is to provide a first guide portion 1021 and a second guide portion 1022 on the support member 11. In this case, the support member 11 is movably connected to the left and right adjacent support members 11 through the first guide portion 1021 and the second guide portion 1022 respectively. That is, there is only one movable connection point between adjacent support members 11, and the stability between the support members 11 is poor.

[0069] The second technical solution is to provide a plurality of first guide portions 1021 and a plurality of second guide portions 1022 on the support member 11. Similarly, in this case, the support member 11 is movably connected to the second guide portions 1022 and the first guide portions 1021 on the left and right adjacent support members 11 respectively through the plurality of first guide portions 1021 and the plurality of second guide portions 1022. It can be understood that the provision of a plurality of first guide portions 1021 and a plurality of second guide portions 1022 on the support member 11 provides more movable connection points between the support member 11 and the adjacent support members 11, compared to the provision of a single first guide portion 1021 and a single second guide portion 1022 on the support member 11. Although this improves the stability of the hinge component 100, it is not conducive to the stacking of the hinge component 100 in a lightweight and thin structure.

[0070] like Figure 1 and Figure 2 As described above, two first guide portions 1021 and two second guide portions 1022 are provided on the support member 11. The first guide portion 1021 and the second guide portion 1022 on the support member 11 are respectively located at the front and rear ends of the support member 11, and face the left and right sides of the support member 11, respectively. For example, the first guide portion 1021 extends to the left, with one end thereof extending beyond the left edge of the support member 11; similarly, the second guide portion 1022 extends to the right, with one end thereof extending beyond the right edge of the support member 11, thereby enabling the first guide portion 1021 of one support member 11 to be movably connected to the second guide portion 1022 of an adjacent support member 11. Moreover, each support member 11 has a movably connected point with its left and right adjacent support members 11 at both the front and rear ends of the support member 11. This not only achieves a stable connection between multiple support members 11, but also facilitates the stacking of the hinge component 100 with a lightweight and thin structure.

[0071] In some embodiments, the support member 11 includes a first body 13 and at least one first connecting portion 12. The first connecting portion 12 is connected to the first body 13 and is located on at least one side in the thickness direction of the first body 13. Each first connecting portion 12 is provided with at least one first guide portion 1021 and a second guide portion 1022. It is understood that the first connecting portion 12 is used to support the first guide portion 1021 and the second guide portion 1022.

[0072] In this embodiment, the thickness direction of the first body 13 is Figure 1 The upper and lower directions in the figure are consistent. It can be understood that the first body 13 has an upper surface and a lower surface arranged in an upward and downward direction relative to each other, and the first connecting portion 12 is arranged below the lower surface of the first body 13; or the first connecting portion 12 is arranged above the upper surface of the first body 13; or the first connecting portion 12 is arranged below the lower surface of the first body 13 and above the upper surface of the first body 13. Advantageously, the first connecting portion 12 is arranged below the lower surface of the first body 13, and the flexible screen is directly placed above the upper surface of the first body 13 to achieve the connection between the first body 13 and the flexible screen.

[0073] The support member 11 is provided with at least one first connecting portion 12, and each first connecting portion 12 is provided with at least one first guide portion 1021 and a second guide portion 1022. It can be understood that one or more first connecting portions 12 are provided on the support member 11; and each first connecting portion 12 is provided with at least one first guide portion 1021 and at least one second guide portion 1022; this is the same as the understanding that at least one first guide portion 1021 and at least one second guide portion 1022 are provided on the above-mentioned support member 11, and will not be repeated here.

[0074] In some embodiments, the first guide portion 1021 includes a first sliding groove 10211 and / or a first lever 10212. When the first guide portion 1021 is the first sliding groove 10211, the second guide portion 1022 includes a second lever 10222, and the first sliding groove 10211 is slidably connected to the second lever 10222 of the second guide portion 1022. The first lever 10212 includes a rotating shaft structure. When the first guide portion 1021 is the first lever 10212, the second guide portion 1022 includes a second sliding groove 10221, and the first lever 10212 is slidably connected to the second sliding groove 10221 of the second guide portion 1022 via the rotating shaft structure. The first sliding groove 10211 and the second sliding groove 10221 can be closed arc-shaped sliding grooves.

[0075] It is understandable that the first guide portion 1021 includes a first sliding groove 10211 ; or the first guide portion 1021 includes a first shifting rod 10212 ; or the first guide portion 1021 includes the first sliding groove 10211 and the first shifting rod 10212 .

[0076] Among them, when the first guide part 1021 includes a first sliding groove 10211, the second guide part 1022 includes a second lever 10222, wherein the first sliding groove 10211 and the second lever 10222 are respectively facing the left and right sides of the first body 13, and the first sliding groove 10211 is slidingly connected to the second lever 10222 on the adjacent first body 13; similarly, when the first guide part 1021 includes the first lever 10212, it is the same as the above situation and will not be repeated.

[0077] Specific examples Figure 2 As shown, when the first guide portion 1021 includes a first sliding groove 10211 and a first deflecting rod 10212, the second guide portion 1022 includes a second deflecting rod 10222 and a second sliding groove 10221. For example, the first sliding groove 10211 and the first deflecting rod 10212 face the right side of the first body 13, and the optional first sliding groove 10211 and the first deflecting rod 10212 are respectively located at the front and rear ends of the first body 13; the second sliding groove 10221 and the second deflecting rod 10222 face the left side of the first body 13, and are located at the front and rear ends of the first body 13, wherein the first sliding groove 10211 is slidably connected to the second deflecting rod 10222 on the first body 13 adjacent to the left; and the first deflecting rod 10212 is slidably connected to the second sliding groove 10221 on the first body 13 adjacent to the left.

[0078] For example, Figure 2 As shown, the first slide groove 10211 and the second slide groove 10221 may have notches, and the first lever 10212 and the second lever 10222 include a rotating shaft structure, wherein the rotating shaft structure can be understood as a pin. One end of the pin is assembled on the first lever 10212 through a pin hole provided in the first lever 10212, and the other end of the pin is inserted into the notch provided in the first slide groove 10211, thereby achieving a sliding connection between the first lever 10212 and the second slide groove 10221. In this embodiment, the first guide portion 1021 includes the first slide groove 10211 and the first lever 10212. Compared to the case where the first guide portion 1021 is the first slide groove 10211 or the first lever 10212, the hinge component 100 has greater flexibility.

[0079] In some embodiments, the number of the support members 11 is an odd number.

[0080] The number of support members 11 can be at least three, or an odd number such as five, seven, or nine. The setting of the linkage component 2 can ensure that the support members 11 on the left and right sides that are movably connected to each other move synchronously. The number of support members 11 is an odd number not less than three, which can ensure that the middle support member 11 in the support component 1 does not move, and the support members 11 on the left and right sides both move left and right synchronously relative to the middle support member 11, thereby ensuring the maximum fit to the flexible screen.

[0081] In some embodiments, the linkage assembly 2 includes a first slide 21 and a synchronizer 22 , the first slide 21 is disposed on one of the supports 11 ; one end of the synchronizer 22 is slidably connected to the first slide 21 ; the other end of the synchronizer 22 is hinged to the other support 11 .

[0082] Specific examples Figure 1 As shown, there are two first slides 21, which are symmetrically arranged on the left and right sides of the support assembly 1, located on one support member 11 of the support assembly 1, and are mirror images of each other; there are two synchronizers 22, one end of which is slidably connected to the first slide 21 on one side, and the other end is hinged to the support member 11 in the middle of the support assembly 1. It can be understood that when the support members 11 on the left and right sides of the support assembly 1 rotate relative to the middle support member 11, one end of the two synchronizers 22 on the left and right sides are synchronously hinged to the middle support member 11; and the other end of the synchronizers 22 slides in the first slides 21 on both sides, so that the support members 11 on the left and right sides of the support assembly 1 can move synchronously left and right relative to the middle support member 11.

[0083] In some embodiments, the linkage assembly 2 includes a swing arm assembly 23 , and the swing arm assembly 23 is arranged side by side with the first slide 21 and the synchronizer 22 on at least one support member 11 .

[0084] Specific examples Figure 1 and Figure 3 The linkage assembly 2 also includes a swing arm assembly 23, wherein the swing arm assembly 23 is arranged side by side with the first slide 21 and the synchronizer 22 in the front-to-rear direction of the support member 11. It can be understood that when the number of support members 11 in the support assembly 1 is three or five, wherein the first slide 21 is mirror-symmetrically arranged on the leftmost and rightmost support members 11, one end of the two synchronizers 22 is respectively connected to the left and right first slides 21; the other ends of the two synchronizers 22 are hinged to the middle support member 11 in the support assembly 1, so that the left and right support members 11 in the support assembly 1 can respectively rotate left and right synchronously relative to the middle support member 11.

[0085] When the number of support members 11 in the support assembly 1 is seven, the above-mentioned setting cannot achieve the left and right synchronous rotation of each support member 11 on the left and right sides of the support assembly 1 relative to the middle support member 11. It is advantageous to set a swing arm assembly 23. The setting of the five support members 11 in the middle of the support assembly 1 is like the setting of the above-mentioned synchronizer 22 and the first slide 21. The swing arm assembly 23 is used to connect the outer support member 11 and the inner support member 11, so that the outer support member 11 and the middle support member 11 are kept in linkage.

[0086] It is understandable that when the number of support members 11 in the support assembly 1 is greater than seven, a swing arm assembly 23 needs to be added for every two additional support members 11, so as to achieve left and right synchronous movement of each support member 11 on the left and right sides of the support assembly 1 relative to the middle support member 11.

[0087] In some embodiments, the swing arm assembly 23 includes a second fixed seat 231, a swing arm 232 and a second slide 233, the second fixed seat 231 is fixed on one of the support members 11; one end of the swing arm 232 is hinged to the second fixed seat 231; the other end of the swing arm 232 is slidably connected to the second slide 233, and the second slide 233 is fixed on the other support member 11.

[0088] Specific examples Figure 1 and Figure 3 , wherein there are two second slides 233, which are respectively located on the leftmost and rightmost support members 11 and are mirror images of each other; there are two second fixed seats 231, wherein the support member 11 on which the second fixed seat 231 is set is located between the support member 11 on which the first slide 21 is set and the support member 11 hinged to the synchronizer 22; wherein the support member 11 on which the first slide 21 is set is located between the support member 11 on which the second slide 233 is set and the support member 11 on which the second fixed seat 231 is set; wherein one end of the swing arm 232 is connected to the second slide 233, and slides relative to the second slide 233, and the other end of the swing arm 232 is hinged to the second fixed seat 231.

[0089] When the support members 11 on the left and right sides of the support assembly 1 rotate relative to the middle support member 11 respectively, the support member 11 provided with the second slide 233 and the second fixed seat 231 is linked with the support member 11 provided with the first slide 21 and the synchronizer 22, thereby realizing the left and right synchronous movement of each support member 11 on the left and right sides of the support assembly 1 relative to the middle support member 11.

[0090] In some embodiments, the support assembly 1 includes a first support member 111 located at the outermost side, a second support member 112 arranged adjacent to the first support member 111, a third support member 113 arranged adjacent to the second support member 112, and a fourth support member 114 located in the middle, wherein the second slide 233 is fixed on the first support member 111; the first slide 21 is fixed on the second support member 112; the second fixed seat 231 is fixed on the third support member 113; the fourth support member 114 is provided with a first fixed seat 115, and the first fixed seat 115 is hinged to the other end of the synchronizer 22.

[0091] Specific Figure 3As shown, the support members 11 are arranged from left to right as the first support member 111, the second support member 112, the third support member 113, the fourth support member 114, the third support member 113, the second support member 112, and the first support member 111. It is understood that the left and right first support members 111 are symmetrically arranged relative to the middle fourth support member 114. The same applies to the left and right second support members 112 and the left and right third support members 113. The two second slides 233 are respectively fixed to the two first support members 111 on either side, and the two first slides 21 are respectively fixed to the two second support members 112 on either side. The two second fixing seats 231 are respectively fixed to the two third support members 113 on either side, and the first fixing seat 115 is fixed to the fourth support member 114.

[0092] For example, taking the synchronizer 22 and the swing arm 232 on one side as an example, one end of the synchronizer 22 is hinged to the first fixed seat 115 on the fourth support member 114, and the other end of the synchronizer 22 is slidably connected to the first slide 21 on the second support member 112; one end of the swing arm 232 is hinged to the second fixed seat 231 on the third support member 113, and the other end is slidably connected to the second slide 233 on the first support member 111. The synchronizer 22 can drive the second and third support members 112 and 113 on the left and right sides to rotate synchronously relative to the fourth support member 114; and the swing arm 232 connects the first and third support members 111 and 113. When the second and third support members 112 and 113 on the left and right sides rotate synchronously relative to the fourth support member 114, the first and third support members 111 and 113 remain linked, thereby achieving synchronous rotation of the first support members 111 on the left and right sides relative to the fourth support member 114.

[0093] Optionally, the vertical height of the synchronizer 22 connected to the first fixed seat 115 is the same as the height at which the synchronizer 22 is connected to the first slide 21; and the vertical height of the swing arm 232 is the same as the height at which the swing arm 232 is connected to the second fixed seat 231. In this embodiment, the arrangement of the first fixed seat 115 and the second fixed seat 231 ensures that the synchronizer 22 remains horizontal in the left-right direction when the flexible screen is unfolded, providing stable support for the flexible screen in both the unfolded and folded states.

[0094] In some embodiments, the synchronizer 22 includes a meshing portion 221, a first guide portion 222 and a first hinged portion 223, and the meshing portions 221 on different synchronizers 22 mesh with each other; the first guide portion 222 extends from the meshing portion 221 along the width direction of the support member 11, and a first slide groove 10211 is provided on the first slide seat 21, and the first guide portion 222 is movably inserted in the first slide groove 10211, and the first hinged portion 223 extends from the meshing portion 221 along the length direction of the support member 11, and the first hinged portion 223 is hinged to the first fixed seat 115.

[0095] Optional, such as Figure 3 As shown, the meshing portion 221 is a gear structure, and the gear structures on the different synchronizers 22 on both sides mesh with each other, maintaining absolute synchronization between the support members 11 on the left and right sides of the support assembly 1. The first hinge portion 223 extends from the meshing portion 221 in the front-to-back direction, and the first hinge portion 223 is hinged to the front and rear ends of the first fixed seat 115. Exemplarily, the first hinge portion 223 is a rod pin, wherein pin holes are provided on the first fixed seat 115 and the meshing portion 221, and the rod pin passes through the pin holes on the first fixed seat 115 and the meshing portion 221 respectively, thereby realizing the hinge connection between the synchronizer 22 and the first fixed seat 115. In this embodiment, the hinge connection between the synchronizer 22 and the first fixed seat 115 also includes other possible ways to achieve the hinge connection, which are not listed here.

[0096] The first guide portion 222 extends from the engaging portion 221 along the left and right directions of the support member 11. A first slide groove 10211 is provided on the first slide 21. The first guide portion 222 is movably inserted into the first slide groove 10211. The setting of the first slide groove 10211 can limit the first guide portion 222, so that the first guide portion 222 can move linearly along the first slide groove 10211 in the first slide 21 and be movably inserted into the first slide 21.

[0097] In some embodiments, the swing arm 232 includes a second hinge portion 2321 and a second guide portion 2322; the second hinge portion 2321 is hinged to the second fixed seat 231 at both ends in the length direction of the support member 11; one end of the second guide portion 2322 is connected to the middle part of the second hinge portion 2321; the second slide seat 233 is provided with a second slide groove 10221, and the other end of the second guide portion 2322 is movably inserted into the second slide groove 10221.

[0098] Specific as Figure 1 and Figure 3 The front and rear ends of the second hinged portion 2321 are hingedly connected to the second fixed seat 231. In some embodiments, the second fixed seat 231 includes a second body 2311 and a second support portion 2312. The second support portion 2312 is located on one side of the second body 2311 in the width direction of the support member 11, facing the second slide 233. The second hinged portion 2321 can be understood as an axle pin, wherein one end of the second guide portion 2322 is connected to the middle portion of the axle pin. The second fixed seat 231 is provided with an axle hole, and the two ends of the axle pin respectively pass through the axle holes in the second fixed seat 231, thereby achieving the hinged connection between the second guide portion 2322 and the second fixed seat 231. The other end of the second guide portion 2322 is movably inserted into the second slide slot 10221, and the second guide portion 2322 can move linearly along the second slide slot 10221 within the second slide 233 to achieve the folding and extension of the hinged component.

[0099] In some embodiments, the first fixing seat 115 includes two first supporting portions 1151 , which are opposite to each other and spaced apart. The first hinge portion 223 is hinged to the first supporting portion 1151 , and the engaging portion 221 is located between the two first supporting portions 1151 .

[0100] It should be noted that the first fixing seat 115 includes two first support parts 1151, and the synchronizers 22 on both sides need to be hinged to the first fixing seat 115, so that the overall space occupied by the linkage assembly 2 is smaller, which facilitates the stacking of the lightweight structure of the whole machine and helps to avoid space for other devices.

[0101] In some embodiments, a first recessed portion 211 is provided on the side of the first sliding seat 21 facing the first fixing seat 115 ;

[0102] And / or, a second recessed portion 2331 is provided on a side of the second sliding seat 233 facing the second fixing seat 231 .

[0103] Specific as Figure 1 As shown, the first slide 21 is provided with a first recessed portion 211 on the side facing the first fixed seat 115, and the second slide 233 is provided with a second recessed portion 2331 on the side facing the second fixed seat 231. The provision of the first recessed portion 211 and the second recessed portion 2331 prevents the first fixed seat 115 and the second fixed seat 231 from limiting the first slide 21 and the second slide 233 during the bending process of the hinge component, thereby achieving spatial avoidance of components.
