[0099] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0100] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0101] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0102] With the continuous advancement of technology, foldable screen mobile phones have gradually become the new favorite of the market. While maintaining portability, this device provides a larger screen space, allowing users to enjoy a better visual experience.

[0103] The hinge is a key component that connects the outer shell of a folding screen mobile phone, responsible for supporting and guiding the opening and closing of the screen. Its performance directly affects the overall durability and service life of the mobile phone. An excellent hinge design can keep the screen smooth and stable after repeated folding, while reducing wear and tear and increasing the service life of the device.

[0104] During the folding process of a foldable electronic device, the flexible screen assembly will be subjected to compressive stress or tensile stress due to the inextensibility of the flexible screen assembly. In order to avoid damage to the flexible screen assembly, the hinge structure needs to translate synchronously during the rotation process and adjust the spacing between the supporting assemblies to compensate for the planar expansion and contraction of the flexible screen assembly.

[0105] The hinge structure provided by the present application has a simple structure, high reliability, stronger correlation between rotation and translation, can achieve precise translation during rotation, the spacing adjustment between supporting components is more precise and reliable, and the compensation effect on the flexible screen component is better, which is beneficial to improving the reliability and service life of the hinge structure and the electronic device using the hinge structure.

[0106] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0107] On the one hand, combined with Figure 1 , Figure 2 As shown, this embodiment provides a hinge structure, which includes: a first supporting component 1, a second supporting component 2 and a connecting component 3.

[0108] The connecting assembly 3 includes at least two connecting members 31 and at least one movable member 32; the first ends of the at least two connecting members 31 are rotationally connected to the first support assembly 1 along the first axis 001, and the second ends of the at least two connecting members 31 are movably connected to the second support assembly 2; at least one movable member 32 is coaxially arranged between the first ends of the at least two connecting members 31; the first end of at least one connecting member 31 is provided with a first pushing portion 311, and at least one movable member 32 is provided with a second pushing portion 321, and the first pushing portion 311 and the second pushing portion 321 are abutted; the first pushing portion 311 and the second pushing portion 321 are used to push at least one of the at least two connecting members 31 to move along the first axis 001 through the rotation of the at least two connecting members 31 around the first axis 001.

[0109] In the hinge structure of this embodiment, the first support component 1 and the second support component 2 are connected by a connecting component 3, and the connecting component 3 includes at least two connecting members 31 and at least one movable member 32, wherein at least one connecting member 31 is provided with a first pushing portion 311, and at least one movable member 32 is provided with a second pushing portion 321, and the first pushing portion 311 and the second pushing portion 321 are abutted along the first axis 001. When the connecting member 31 rotates around the first axis 001, the first pushing portion 311 and the second pushing portion 321 interact with each other to push at least one of the at least two connecting members 31 to move along the first axis 001. When the connecting member 31 moves along the first axis 001, the distance between the first support component 1 and the second support component 2 can be adjusted, so that when the hinge structure switches between the closed state and the unfolded state, the flexible screen component 6 can be compensated for in size by utilizing the distance change between the first support component 1 and the second support component 2 to prevent the flexible screen component 6 from being compressed or stretched.

[0110] In some possible implementations, the number of connecting parts 31 can be two, three, four, etc., and the number of movable parts 32 can be one, two, three, etc. The specific number of connecting parts 31 and movable parts 32 is not specifically limited in this application.

[0111] The number of the connecting members 31 provided with the first abutting portion 311 may be one, two, three, etc., and correspondingly, the number of the movable members 32 provided with the second abutting portion 321 may be one, two, three, etc.

[0112] The at least one movable member 32 is coaxially arranged between the first ends of at least two connecting members 31, which can also be described as: the connecting members 31 and the movable member 32 are arranged on the first axis 001 at intervals, and there is at least one movable member 32 between two adjacent connecting members 31. The at least one movable member 32 can have one second abutting portion 321, or two or more second abutting portions 321, which are respectively located on both axial sides of the movable member 32 and axially abut against at least one first abutting portion 311.

[0113] Exemplarily, a first abutting portion 311 is provided at a first end of each connecting member 31 , and a second abutting portion 321 is provided at a first end of each movable member 32 .

[0114] In addition, the first end of the connecting member 31 can be understood as the part of the connecting member 31 closest to the first supporting assembly 1 , and the second end of the connecting member 31 can be understood as the part of the connecting member 31 closest to the second supporting assembly 2 .

[0115] refer to Figure 5As shown, in some possible implementations, the first support assembly 1 includes a middle support plate and a shaft cover, the middle support plate is provided with a support surface 101, the shaft cover is located on the outer side of the middle support plate away from the support surface 101, and the support surface 101 is used to support the flexible screen assembly 6. The first end of the connecting member 31 is rotatably connected to the middle support plate and / or the shaft cover along the first axis 001.

[0116] Optionally, the connection method between the shaft cover and the middle support plate includes but is not limited to snap-fit ​​connection, welding connection, fastener connection, adhesive connection, etc.

[0117] Combination Figure 2 , Figure 3 As shown, in some embodiments, one of the at least two connecting members 31 and the at least one movable member 32 is fixed at a position of the first axis 001 , and the angle of the at least one movable member 32 around the first axis 001 is fixed.

[0118] Through the above arrangement, when at least two connecting members 31 rotate around the first axis 001, the first pushing portion 311 on the connecting member 31 and the second pushing portion 321 on the movable member 32 will rotate relative to each other, wherein the fixed connecting member 31 acts to apply a force to the movable member 32 and other connecting members 31, so that the movable member 32 and the connecting member 31 can move along the first axis 001.

[0119] Combination Figure 2 , Figure 3 As shown, in some embodiments, the first abutting portion 311 includes at least one first protruding structure, and the second abutting portion 321 includes at least one second protruding structure.

[0120] Exemplarily, the first pushing portion 311 includes a plurality of first protrusion structures, which are arranged in a ring on the end face of the connecting member 31 along the first axis 001, and the second pushing portion 321 includes a plurality of second protrusion structures, which are arranged in a ring on the end face of the movable member 32 along the first axis 001.

[0121] The hinge structure includes an unfolded state and a closed state that can be switched between each other; in the unfolded state (see Fig. 9 ), the first protrusion structure and the second protrusion structure are staggered in circumferential position, and there is a first spacing between the first ends of at least two connecting members 31; in the closed state (refer to Figure 8 ), the first protrusion structure and the second protrusion structure are aligned in circumferential positions, and there is a second spacing between the first ends of at least two connecting members 31; wherein the first spacing is different from the second spacing. Exemplarily, the first spacing is smaller than the second spacing.

[0122] When the hinge structure switches from the unfolded state to the closed state, the connecting member 31 and the movable member 32 rotate relative to each other around the first axis 001 (for example, the connecting member 31 rotates around the first axis 001, and the movable member 32 does not rotate), driving the first protrusion structure and the second protrusion structure to rotate relative to each other around the first axis 001, and the first protrusion structure and the second protrusion structure switch from a state in which the circumferential positions are staggered to a state in which the circumferential positions of the first protrusion structure and the second protrusion structure are aligned, and the movable member 32 and the axially movable connecting member 31 are pushed, and the spacing between the axially movable connecting member 31 and the axially fixed connecting member 31 switches from the first spacing to the second spacing, and the spacing increases.

[0123] When the hinge structure switches from a closed state to an unfolded state, the connecting member 31 and the movable member 32 rotate relative to each other around the first axis 001 (for example, the connecting member 31 rotates around the first axis 001, and the movable member 32 does not rotate), driving the first protrusion structure and the second protrusion structure to rotate relative to each other around the first axis 001, and the first protrusion structure and the second protrusion structure switch from a state in which the circumferential positions are aligned to a state in which the circumferential positions of the first protrusion structure and the second protrusion structure are staggered, and the movable member 32 and the axially movable connecting member 31 are pushed, and the spacing between the axially movable connecting member 31 and the axially fixed connecting member 31 switches from the second spacing to the first spacing, and the spacing is reduced.

[0124] Exemplarily, when the hinge structure is in an expanded state, there is a first distance between the first support component 1 and the second support component 2, and when the hinge structure is in a closed state, there is a second distance between the first support component 1 and the second support component 2, wherein the first distance is smaller than the second distance.

[0125] Combination Figure 2 , Figure 3 As shown, in some embodiments, the position of the first end of one of the connecting members 31 along the first axis 001 is fixed, and the position of the first ends of the remaining connecting members 31 along the first axis 001 is variable; the angle of at least one movable member 32 around the first axis 001 is fixed, and the position of at least one movable member 32 along the first axis 001 is variable.

[0126] Through the above arrangement, the fixed-position connecting member 31 provides an axial thrust to the movable member 32 and the remaining connecting members 31 through the first pushing portion 311, and the movable member 32 with a fixed angle cannot rotate, so that the second pushing portion 321 and the second pushing portion 321 rotate relative to each other, so that the hinge structure can utilize the rotational torque of the connecting member 31 to convert it into an axial force that pushes the connecting member 31 to move along the first axis 001.

[0127] Combination Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the connecting member 31 includes a first connecting member 3101 and a second connecting member 3102; the first connecting member 3101 is movably connected to the second supporting assembly 2 along the first direction A, and the second connecting member 3102 is movably connected to the second supporting assembly 2 along the second direction B; the first direction A is the direction in which the first supporting assembly 1 and the second supporting assembly 2 approach or move away from each other, and the first direction A is perpendicular to the direction of the first axis 001; the angle between the second direction B and the direction of the first axis 001 is α, where 0<α<90°. The first end of the first connecting member 3101 is fixed along the first axis 001, and the first end of the second connecting member 3102 is variable along the first axis 001.

[0128] In this embodiment, the first connecting member 3101 is movably connected to the second supporting assembly 2 along the first direction A, and the first connecting member 3101 can move relatively with the second supporting assembly 2 along the first direction A. The second connecting member 3102 is movably connected to the second supporting assembly 2 along the second direction B, and the second connecting member 3102 can move relatively with the second supporting assembly 2 along the second direction B. Since the first direction A is perpendicular to the direction of the first axis 001, and the second direction B is at an angle α to the first axis 001, when the spacing between the first connecting member 3101 and the second connecting member 3102 along the direction of the first axis 001 changes, the second connecting member 3102 will push the second supporting assembly 2 to approach or move away from the first supporting assembly 1.

[0129] Exemplarily, the value of the angle α between the second direction B and the direction of the first axis 001 is, for example, 5°, 10°, 15°, 20°, 30°, 45°, 60°, 75°, 85°, etc.

[0130] Combination Figure 5 , Figure 7 As shown, in some embodiments, a fifth hinge portion 316 is provided at the first end of the second connecting member 3102, and the fifth hinge portion 316 is hinged to the first support assembly 1.

[0133] Through the above arrangement, when the second connecting member 3102 moves along the first axis 001, the angle between the second connecting member 3102 and the connecting rod member 33 changes within the range of 0-180°, so that the second connecting member 3102 can transmit a pulling force or a pushing force to the second support assembly 2 through the connecting rod member 33, so that the second support assembly 2 is close to or away from the first support assembly 1.

[0134] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one connecting rod member 33 is hinged to the second end of the second support assembly 2 and the second connecting member 3102, respectively; when the second connecting member 3102 moves toward one end of the first axis 001, the angle between the second connecting member 3102 and the at least one connecting rod member 33 increases, and the distance between the second support assembly 2 and the first support assembly 1 increases; when the second connecting member 3102 moves toward the other end of the first axis 001, the angle between the second connecting member 3102 and the at least one connecting rod member 33 decreases, and the distance between the second support assembly 2 and the first support assembly 1 decreases.

[0135] Through the above arrangement, when the hinge structure switches from the expanded state to the closed state, the second connecting member 3102 moves in a direction away from the first connecting member 3101, and the angle between the second connecting member 3102 and the connecting rod member 33 increases. The second connecting member 3102 and the connecting rod member 33 push the second support assembly 2 outward, so that the second support assembly 2 is away from the first support assembly 1.

Optionally, the quadrilateral is a parallelogram. By arranging the first link 331 and the second link 332 into a parallelogram four-bar linkage, the activity of the second support assembly 2 can be made more stable and reliable.

[0144] structure Figure 4 As shown, in some embodiments, the second supporting assembly 2 is provided with a groove 25 , and the first hinge portion 23 and the third hinge portion 24 are located in the groove 25 .

[0145] By arranging the groove 25 on the second support component 2 and arranging the first hinge part 23 and the third hinge part 24 in the groove 25, it is helpful to reduce the thickness of the second support component 2 and the thickness of the entire hinge structure.

By utilizing the fifth sliding portion 21 arranged along the second direction B, when the second connecting member 3102 moves along the first axis 001, the second support assembly 2 can be pushed outward or pulled inward, so that the second support assembly 2 is away from or close to the first support assembly 1.

[0147] Exemplarily, the fifth sliding portion 21 is a sliding groove structure, and the second end of the second connecting member 3102 is slidably connected in the fifth sliding portion 21 .

[0148] Combination Figure 4 As shown, in some embodiments, the second end of the first connecting member 3101 is provided with a first sliding portion 312, and the second supporting assembly 2 is provided with a second sliding portion 22, and the first sliding portion 312 and the second sliding portion 22 are slidably matched along the first direction A; one of the first sliding portion 312 and the second sliding portion 22 is a groove 25 structure, and the other of the first sliding portion 312 and the second sliding portion 22 is a convex rail structure.

[0149] Through the above arrangement, the first connecting member 3101 can rotate together with the second supporting assembly 2 around the first axis 001 without affecting the second supporting assembly 2 approaching or moving away from the first supporting assembly 1, thereby realizing the expansion and closing of the hinge structure.

[0150] Combination Figure 4 , Figure 5 As shown, in some embodiments, the connecting assembly 3 includes a guide rod member 34, which is arranged on the first support assembly 1 along the first axis 001, and the first ends of at least two connecting members 31 and at least one movable member 32 are respectively connected to the guide rod member 34.

[0151] The connecting member 31 and the movable member 32 of the connecting assembly 3 can be connected to the first supporting assembly 1 along the first axis 001 respectively by using the guide rod member 34 , so as to realize the connection between the connecting assembly 3 and the first supporting assembly 1 .

By using the at least one guide rod support 11 on the first support assembly 1, the guide rod member 34 can be arranged on the first support assembly 1 along the first axis 001.

[0153] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the connecting assembly 3 includes at least one elastic member 35, and the at least one elastic member 35 is located on the first axis 001, and the at least one elastic member 35 can be stretched or compressed when at least one of the at least two connecting members 31 moves along the first axis 001.

[0154] Through the above arrangement, the connection assembly 3 can utilize at least one elastic member 35 to provide elastic restoring force for the connection member 31, so that the hinge structure has a damping feeling.

[0155] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, at least one elastic member 35 is sleeved on the guide rod member 34; the guide rod member 34 is provided with a first limiting portion 341 and a second limiting portion 342 arranged along the axial direction; the first limiting portion 341 is abutted and connected with the second connecting member 3102, and the second limiting portion 342 is connected to one axial end of at least one elastic member 35, and the other end of at least one elastic member 35 is fixed; when the second connecting member 3102 moves along the first axis 001, the second connecting member 3102 pushes the guide rod member 34 to move axially through the first limiting portion 341, and the guide rod member 34 stretches or compresses at least one elastic member 35 through the second limiting portion 36.

[0156] In this embodiment, when the second support component 2 rotates relative to the first support component 1, at least two connecting members 31 are driven to rotate around the first axis 001, wherein the second connecting member 3102 moves along the first axis 001 under the action of the first pushing portion 311 and the second pushing portion 321, and the second connecting member 3102 pushes the guide rod member 34 to move axially through the first limiting portion 341, and one end of the elastic member 35 is connected to the second limiting portion 342, so that the elastic member 35 is axially stretched or axially compressed, and the elastic force is fed back to the second support component 2 through the guide rod member 34 and the second connecting member 3102, thereby generating a sense of rotational damping.

[0157] In some embodiments, the first limiting portion 341 is a shoulder structure or a retaining ring structure; and / or the second limiting portion 342 is a shoulder structure or a retaining ring structure.

[0158] Combination Figure 2 , Figures 4 to 6 As shown, in some embodiments, the connecting component 3 also includes at least one limit member 36 and a limit guide rod 37, the first end of at least one limit member 36 is movably connected to the guide rod member 34, the second end of at least one limit member 36 is connected to the limit guide rod 37, the limit guide rod 37 extends parallel to the axial direction of the guide rod member 34, and is respectively connected to at least two connecting members 31.

[0159] By arranging at least one limiter 36 on the guide rod 34, the limiter 36 connects at least two connecting members 31 together through the limiter guide rod 37, so that the consistency of the at least two connecting members 31 during rotation is better, which is beneficial to improving the working accuracy of the hinge structure.

[0160] Combination Figure 2 As shown, in some embodiments, the first end of the stopper 36 is provided with a third abutting portion 361, and the third abutting portion 361 abuts against one of the first abutting portion 311 and the second abutting portion 321 along the first axis 001. By arranging the third abutting portion 361 on the stopper 36, the number of working abutting portions in the connecting assembly 3 can be increased, thereby increasing the conversion efficiency of the rotation and movement of the connecting member 31 by increasing the number of abutting portions along the first axis 001. When the rotation angle of the connecting member 31 is fixed, a pair of abutting portions can push the connecting member 31 to move a distance of n when working, and two pairs of abutting portions can push the connecting member 31 to move a distance of 2n when working simultaneously, and multiple pairs of abutting portions can push the connecting member 31 to move a distance of x×n when working simultaneously. The distance that the connecting member 31 can move is proportional to the number of working abutting portions.

[0161] Combination Figure 5 and Figure 7 As shown, in some embodiments, the first end of the stopper 36 is further provided with a second support portion 362, and in the unfolded state, the surface of the second support portion 362 is spliced ​​and aligned with the support surface 101 of the first support assembly 1. When the hinge structure is in the unfolded state, the second support portion 362 is spliced ​​and aligned with the support surface 101 of the support plate in the first support assembly 1, and jointly supports the flexible screen assembly 6.

[0162] Combination Figure 1 , Figures 4 to 6As shown, in some embodiments, the hinge structure also includes a third support component 4; the connecting component 3 includes a first connecting component 3013 arranged corresponding to the first axis 001 and a second connecting component 3023 arranged corresponding to the second axis 002, wherein the second axis 002 is parallel to the first axis 001 and is arranged at intervals along the first direction A; the second support component 2 is connected to the first side of the first support component 1 along the first direction A through the first connecting component 3013; the third support component 4 is connected to the second side of the first support component 1 along the first direction A through the second connecting component 3023.

[0163] The hinge structure of this embodiment connects the second support component 2 and the third support component 4 to the two sides of the first support component 1 using the first connecting component 3013 and the second connecting component 3023 respectively, so that the hinge structure has three parts connected in sequence, which can meet the requirements of unfolding and closing of the foldable electronic device.

[0164] When the hinge structure switches from the expanded state to the closed state, the second support assembly 2 and the third support assembly 4 rotate toward the same side of the first support assembly 1, and when the hinge structure switches from the closed state to the expanded state, the third support assembly 4 and the third support assembly 4 rotate in opposite directions respectively.

[0165] Combination Figures 4 to 7 As shown, in some embodiments, at least one movable member 32 in the first connecting component 3013 is connected to at least one movable member 32 in the second connecting component 3023 so that the two groups of movable members 32 move synchronously along the first axis 001.

[0166] Through the above arrangement, during the rotation of the second support assembly 2 and the third support assembly 4, the spacing between the second support assembly 2 and the third support assembly 4 and the first support assembly 1 is always kept equal.

[0167] Thus, when the first support assembly 1 and the second support assembly 2 and the third support assembly 4 are used to jointly support the flexible screen assembly 6, the spacing between the second support assembly 2 and the third support assembly 4 and the first support assembly 1 remains equal, and the flexible screen assembly 6 will not be pulled or squeezed during the rotation and folding process, that is, it will not be subjected to tensile stress and compressive stress, which is beneficial to prevent damage to the flexible screen assembly 6 and to reduce creases on the surface of the flexible screen assembly 6.

[0168] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, two groups of movable parts 32 are connected to form a connecting block 303; illustratively, the two groups of movable parts 32 can be an integrated structure or a split structure that is assembled and connected.

[0170] The connection block 303 utilizes the third sliding portion 3031 and the fourth sliding portion 12 to slide with the first support assembly 1, which is beneficial to improving the movement stability of the two groups of movable parts 32 in the connection block 303 and improving the folding stability of the hinge structure.

[0171] Combination Figure 5 As shown, in some embodiments, an avoidance gap 13 is provided on the first support assembly 1; the position of the avoidance gap 13 corresponds to the second connecting member 3102 that can move along the first axis 001, and the avoidance gap 13 is used to provide an avoidance space for the second connecting member 3102.

[0172] The avoidance notch 13 is used to provide an avoidance space for the second connecting member 3102 , so that the second connecting member 3102 has sufficient rotation and movement space, thereby preventing the second connecting member 3102 and the first supporting assembly 1 from interfering with each other.

[0173] In some embodiments, the distance between the inner wall of the avoidance notch 13 and the second connecting member 3102 gradually decreases in the direction away from the first axis 001, which is consistent with the movement trajectory of the second connecting member 3102, and is beneficial to reducing the gap between the inner wall of the avoidance notch 13 and the second connecting member 3102, thereby improving the flatness of the supporting surface 101 of the middle support plate, and ensuring the supporting effect of the middle support plate on the flexible screen assembly 6.

[0174] In some embodiments, the avoidance gap 13 has one or more of the following shapes: rectangle, triangle, trapezoid, and the avoidance gap 13 of the above shapes can meet the avoidance requirements of the second connecting member 3102.
