Description

Technical Field

[0001] The utility model relates to the technical field of hinges, and in particular to a hinge structure. Background Art

[0002] With the development of science and technology, electronic devices such as mobile phones, tablet computers, players and laptop computers have been widely used in people's daily lives. At present, in order to facilitate the use of electronic devices, electronic device brackets are usually used to support and fix electronic devices. The hinge structure of the electronic device bracket in the related art generally provides a damping member on the rotating shaft so that the damping member can provide friction to the rotating shaft. Under the action of the damping member, the second hinge of the hinge structure can be suspended at will relative to the first hinge of the hinge structure during the rotation process.

[0003] The damping force of the damping element depends on the length of the damping element. In the related technology, the damping element is generally designed according to the length of the rotating shaft. However, after the damping element is produced and assembled on the rotating shaft, it needs to be tested. If the friction force is found to be too large or too small during the test, it will cause product defects. At this time, it is necessary to redesign the length of the damping element and re-produce it, resulting in production waste. Utility Model Content

[0034] In order to enable those skilled in the art to better understand the implementation scheme of the present utility model, the technical scheme in the implementation scheme of the present utility model will be clearly and completely described below in conjunction with the drawings in the implementation scheme of the present utility model. Obviously, the described implementation scheme is only a part of the implementation scheme of the present utility model, not all of the implementation schemes. Based on the implementation scheme in the implementation scheme of the present utility model, all other implementation schemes obtained by those skilled in the art without making creative work are within the scope of protection of the implementation scheme of the present utility model.

[0035] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0036] Please also read Figures 1 to 3 The embodiment of the utility model provides a hinge structure 100 , which includes a first hinge 11 , a second hinge 12 , a first rotating shaft 131 and a plurality of damping members 14 .

[0037] Among them, the first hinge 11 and the second hinge 12 can both be annular hinges, for example, the first hinge 11 and the second hinge 12 can both be annular brackets, and the hinge structure 100 can be used as a bracket, so as to meet the use requirements of placing objects, electronic devices, etc. In other embodiments, the first hinge 11 and the second hinge 12 can also be used only as a connection function, and by connecting functional parts to the hinge structure 100, the overall structure has corresponding functions, for example, by connecting a bracket to the first hinge 11, the entire structure can be used as a bracket.

[0038] In some embodiments, the first hinge 11 and the second hinge 12 are rotatably connected via a first rotating shaft 131. A plurality of damping members 14 are sleeved on the first rotating shaft 131, and a plurality of damping members 13 are stacked along the length direction of the first rotating shaft 131. In this way, the plurality of damping members 14 can provide friction for the first rotating shaft 131. When the torque acting on the first rotating shaft 131 is greater than the friction, the first rotating shaft 131 can overcome the friction to rotate, so that the first hinge 11 and the second hinge 12 can rotate relative to each other; when the torque acting on the first rotating shaft 131 disappears, the first rotating shaft 131 can stop rotating under the action of the friction and remain in the position after rotation, so that the first hinge 11 and the second hinge 12 can stop rotating and remain in the state after rotation, and the first hinge 11 and the second hinge 12 will not rotate freely due to the disappearance of the torque.

[0039] In this way, the number of damping members 14 sleeved on the first rotating shaft 131 can be selectively adjusted to adjust the length of the damping member 14 sleeved on the first rotating shaft 131, thereby changing the friction between the first rotating shaft 131 and the damping member 14, so as to achieve the adjustability of the friction between the first rotating shaft 131 and the damping member 14, which is also helpful to improve the adaptability of multiple damping members 14 and the first rotating shaft 131, and help to reduce the waste of resources. In addition, the hinge structure is simple in adjusting the friction between the first rotating shaft 131 and the damping member 14, which is convenient for users to operate.

[0040] Exemplarily, when the friction between the first rotating shaft 131 of the hinge structure 100 and the damping member 14 is small and does not meet product requirements, an appropriate number of damping members 14 can be added to the first rotating shaft 131 to increase the friction between the first rotating shaft 131 and the damping member 14; when the friction between the first rotating shaft 131 of the hinge structure 100 and the damping member 14 is large, an appropriate number of damping members 14 can be reduced on the first rotating shaft 131 to reduce the friction between the first rotating shaft 131 and the damping member 14.

[0041] In this way, the multiple damping members 14 are sleeved on the first rotating shaft 131, which helps to improve the versatility of the multiple damping members 14, so that the user can change the friction between the first rotating shaft 131 and the damping member 14 by adding or reducing a single damping member 14, thereby helping to reduce the situation where a batch of damping members 14 are scrapped due to a single damping member 14 failing to be tested, and also helping to reduce the situation where the mold for manufacturing the damping member 14 is scrapped due to a single damping member 14 failing to be tested. In addition, the damping member 14 removed from the first rotating shaft 131 can be repeatedly applied to another first rotating shaft 131, which helps to improve the utilization rate of the damping member 14, thereby helping to reduce the waste of resources.

[0042] Among them, the "multiple" in the above and below refers to two or more than two. For example, the damping elements 14 may include two, three, four, five, six, seven, eight, nine, ten or other quantities, which can be specifically set according to actual conditions.

[0043] In some embodiments, two adjacent damping members 14 are disposed in contact with each other, which helps to improve the compactness of the structure between the multiple damping members 14 and helps to ensure the damping effect of the multiple damping members 14 on the first rotating shaft 131 .

[0044] In some embodiments, two adjacent damping elements 14 are spaced apart from each other, for example, multiple damping elements 14 may be spaced apart from each other, which helps to improve the adjustable flexibility of the multiple damping elements 14 and can be specifically set according to actual conditions.

[0045] Please also read Figures 4 to 6 In some embodiments, each damping member 14 may include a damping portion 141 , and the damping portion 141 includes a shaft through hole 146 . The damping member 14 is sleeved on the first shaft 131 through the shaft through hole 146 , which helps to ensure the connection between the damping member 14 and the first shaft 131 .

[0046] In some embodiments, the damping part 141 also includes a deformation notch 147 connecting the shaft through hole 146 and the outer side of the damping part 141. In this way, the deformation notch 147 allows the damping part 141 to have the ability to deform. When the first shaft 131 and the damping member 14 rotate, the deformation notch 147 allows the damping part 141 at the position of the deformation notch 147 to deform outward, thereby helping to reduce the contact friction between the first shaft 131 and the damping part 141, and helping to reduce the situation where the damping part 141 fails due to excessive friction between the first shaft 131 and the damping part 141, thereby helping to extend the service life of the damping member 14. The shaft through hole 146 and the deformation notch 147 in this embodiment can be set separately or simultaneously according to actual conditions, and are not limited here.

[0047] An oil storage portion 148 may be formed between the deformation notch 147 and the first rotating shaft 131. For example, the oil storage portion 148 may be an oil storage tank. Thus, when the first rotating shaft 131 rotates, the lubricating oil in the hinge structure 100 used to lubricate the first rotating shaft 131 may be squeezed and overflow, and the overflowed lubricating oil may be stored in the oil storage portion 148, which helps to reduce the overflowed lubricating oil from flowing to the first hinge 11 or the second hinge 12, thereby helping to reduce the first hinge 11 or the second hinge 12 from being dirty.

[0048] In addition, the lubricating oil in the oil storage portion 148 can also lubricate the first rotating shaft 131 and the damping member 14 , which helps to extend the lubricating effect time of the lubricating oil on the first rotating shaft 131 , and helps to better reduce the wear caused by friction and heat between the first rotating shaft 131 and the damping member 14 .

[0049] In some embodiments, the inner side wall 1461 of the shaft through hole 146 is provided with a deformation groove 149 . When the damping member 14 is sleeved on the first shaft 131 , a gap 150 is formed between the deformation groove 149 and the first shaft 131 .

[0050] In this way, the gap 150 can provide a deformation space for the damping part 141. When the damping part 141 is deformed through the deformation groove 149, the inner side of the damping part 141 can be deformed to balance the stress of the outer side of the damping part 141, thereby helping to extend the service life of the damping part 141.

[0051] In addition, when the first rotating shaft 131 rotates, the lubricating oil in the hinge structure 100 used to lubricate the first rotating shaft 131 will be squeezed and overflow. The overflowed lubricating oil can be stored in the gap 150, which helps to reduce the overflow of the lubricating oil from both ends of the first rotating shaft 131, thereby helping to reduce the dirtiness of the hinge structure 100.

[0052] In some embodiments, each damping portion 141 is provided with a plurality of deformation grooves 149 , and the plurality of deformation grooves 149 are arranged at intervals along the circumference of the shaft through hole 146 . For example, each damping portion 141 may be provided with two, three, four or other numbers of deformation grooves 149 , which may be specifically arranged according to actual conditions.

[0053] In this way, the multiple deformation grooves 149 help the inner side of the damping part 141 to deform better, and also help to ensure that a plurality of gaps 150 can be formed in the circumference of the shaft through hole 146 to store the lubricating oil overflowing from the first shaft 131, so that the lubricating oil stored in the gaps 150 can continue to lubricate multiple positions of the first shaft 131, which helps to reduce the wear caused by friction and heat between the first shaft 131 and the damping member 14.

[0054] In some embodiments, the plurality of damping parts 141 all have deformation notches 147, and the deformation notches 147 of the plurality of damping parts 141 are arranged in a straight line along the length direction of the first rotating shaft 131. In this way, the outer sides of the plurality of damping parts 141 can be deformed from the same position, so as to better reduce the contact friction between the first rotating shaft 131 and the damping part 141.

[0055] In some embodiments, the plurality of damping parts 141 all have deformation grooves 149, and the deformation grooves 149 of the plurality of damping parts 141 are arranged in a straight line along the length direction of the first rotating shaft 131. In this way, the inner sides of the plurality of damping parts 141 can be deformed from the same position to better balance the stress on the outer sides of the plurality of damping parts 141 when deformed.

[0056] Please also read Figures 4 to 6 In some embodiments, the first hinge 11 may include a shaft accommodating portion 111, a plurality of damping members 14 are sleeved on the first shaft 131 and are disposed together with the first shaft 131 in the shaft accommodating portion 111, the damping members 14 are fixed relative to the shaft accommodating portion 111, the damping members 14 are rotatably connected to the first shaft 131, and both ends of the first shaft 131 are respectively connected to the second hinge 12. The shaft accommodating portion 111 may be a sleeve structure, a groove structure, etc., and may be specifically configured according to actual conditions.

[0057] In this way, the shaft accommodating portion 111 can provide space for accommodating the first shaft 131 and multiple damping members 14, which helps to improve the compactness of the hinge structure 100 and also helps to reduce the possibility of the first shaft 131 loosening from the first hinge 11, thereby helping to ensure the normal operation of the first shaft 131.

[0058] In addition, the number of damping members 14 sleeved on the first rotating shaft 131 can be selectively adjusted to adjust the length of the damping member 14 sleeved on the first rotating shaft 131, thereby changing the friction between the first rotating shaft 131 and the damping member 14. This helps to improve the adjustability of the friction between the first rotating shaft 131 and the damping member 14, and also helps to improve the fit between multiple damping members 14 and the first rotating shaft 131, thereby helping to reduce waste of resources.

[0059] In some embodiments, the damping member 14 may further include a snap-fit ​​portion 142, which is disposed on the outer peripheral side of the damping portion 141. The first hinge 11 also includes a limiting portion 1111 disposed on the shaft accommodating portion 111. The snap-fit ​​portion 142 is snap-fitted in the limiting portion 1111 to fix the damping member 14 relative to the shaft accommodating portion 111, so that the damping member 14 will not rotate relative to the shaft accommodating portion 111.

[0060] Thus, when the first rotating shaft 131 rotates, the damping member 14 is fixed in the rotating shaft receiving portion 111 , and the damping member 14 can rotate relative to the first rotating shaft 131 and provide friction force for the first rotating shaft 131 , thereby helping to ensure the damping effect of the damping member 14 on the first rotating shaft 131 .

[0061] In addition, the limiting portion 1111 can also locate the installation position of the damping member 14 , which helps to improve the accuracy of the installation position of the damping member 14 and also helps to improve the installation efficiency of the damping member 14 .

[0062] For example, when it is necessary to sleeve the damping member 14 on the first rotating shaft 131, the damping portion 141 can be directly sleeved on the first rotating shaft 131, and then the installation position of the locking portion 142 is positioned by the limiting portion 1111, and finally the locking portion 142 is directly limited in the limiting portion 1111 to complete the installation of the damping member 14, thereby improving the installation efficiency of the damping member 14.

[0063] Please also read Figures 7 to 11 In some embodiments, the hinge structure 100 may further include a second rotating shaft 133, the first rotating shaft 131 is connected to the first hinge 11, the second rotating shaft 133 is connected to the second hinge 12, the rotating shaft through hole 146 includes a first rotating shaft through hole 1441 and a second rotating shaft through hole 1451, the first rotating shaft 131 is passed through the first rotating shaft through hole 1441, and the second rotating shaft 133 is passed through the second rotating shaft through hole 1451.

[0064] In this way, the first rotating shaft 131, the second rotating shaft 133 and the multiple damping members 14 can meet the requirements of relative rotation of the second hinge 12 and the first hinge 11, and the multiple damping members 14 are sleeved on the first rotating shaft 131 and the second rotating shaft 133, so that the multiple damping members 14 can provide friction force for the first rotating shaft 131 and the second rotating shaft 133 respectively, which helps to ensure that the second hinge 12 and the first hinge 11 can rotate relative to each other.

[0065] In addition, the number of damping members 14 sleeved on the first rotating shaft 131 and the second rotating shaft 133 can be selectively adjusted to adjust the length of the damping members 14 sleeved on the first rotating shaft 131 and the second rotating shaft 133, thereby changing the friction between the first rotating shaft 131 and the second rotating shaft 133 and the damping member 14, which helps to improve the adjustability of the friction between the first rotating shaft 131 and the second rotating shaft 133 and the damping member 14, and also helps to improve the adaptability of multiple damping members 14 and the first rotating shaft 131 and the second rotating shaft 133, thereby helping to reduce waste of resources.

[0066] In some embodiments, the first rotating shaft 131 and / or the second rotating shaft 133 are rotatably connected to the damping member 14 . For example, the first rotating shaft 131 is rotationally connected with the damping member 14, and the second rotating shaft 133 is stationary relative to the damping member 14. The second hinge 12 can be rotated relative to the first hinge 11 so that the second hinge 12 drives the second rotating shaft 133 and the damping member 14 to rotate relative to the first rotating shaft 131. For another example, the first rotating shaft 131 is stationary relative to the damping member 14, and the second rotating shaft 133 is rotationally connected with the damping member 14. The second rotating shaft 133 can be rotationally connected with the damping member 14 by rotating the second hinge 12 relative to the first hinge 11. For another example, the first rotating shaft 131 is rotationally connected with the damping member 14, and the second rotating shaft 133 is rotationally connected with the damping member 14. The second hinge 12 can be rotated relative to the first hinge 11 so that the second hinge 12 drives the second rotating shaft 133 to rotate relative to the damping member 14. At this time, the damping member 14 will rotate relative to the first rotating shaft 131 to ensure the normal operation of the hinge structure 100. The specific settings can be made according to actual conditions.

[0067] In some embodiments, the first rotating shaft 131 and the second rotating shaft 133 are both rotatably connected to the damping member 14, and the damping member 14 can rotate relative to the first rotating shaft 131 and the second rotating shaft 133, respectively, and provide friction force to the first rotating shaft 131 and the second rotating shaft 133, respectively, thereby helping to ensure the damping effect of the damping member 14 on the first rotating shaft 131 and the second rotating shaft 133.

[0068] In addition, the first rotating shaft 131 and the second rotating shaft 133 are both rotatably connected to the damping member 14 so that during the rotation of the second hinge 12 relative to the first hinge 11, the position of the second rotating shaft 133 can be raised, thereby allowing the position of the second hinge 12 to be raised, helping to reduce the situation where the boss edge of the first hinge 11 blocks the rotation of the second hinge 12, thereby helping to ensure the smooth rotation of the second hinge 12 and also helping to increase the opening and closing angle of the second hinge 12 relative to the first hinge 11.

[0069] Exemplarily, the second hinge 12 may have a closed position (eg Fig. 9 ) and the expansion position (such as Fig.10 ), when the second hinge 12 is in the closed position, the first rotating shaft 131 and the second rotating shaft 133 can be located in the same horizontal plane, and the second rotating shaft 133 can be located on the right side of the first rotating shaft 131, and the angle between the first hinge 11 and the second hinge 12 is 0 degree; when the second hinge 12 is in the expanded position, the first rotating shaft 131 and the second rotating shaft 133 can be located in the same vertical plane, and the second rotating shaft 133 can be located above the first rotating shaft 131, and the angle between the first hinge 11 and the second hinge 12 is 180 degrees.

[0070] When the second hinge 12 is in the closed position and starts to rotate relative to the first hinge 11, the first rotating shaft 12 is rotatably connected to the damping member 14 so that the second hinge 12 and the second rotating shaft 133 can rotate relative to the first rotating shaft 131 through the damping member 14, and at this time, the positions of the second rotating shaft 133 and the second hinge 12 are raised relative to the position of the first rotating shaft 131. When the second hinge 12 and the second rotating shaft 133 continue to rotate relative to the first rotating shaft 131 to form an angle of 90 degrees with the first hinge 11, the positions of the first rotating shaft 131 and the second rotating shaft 133 can be changed from the original horizontal position to the vertical position, and the positions of the second hinge 12 and the second rotating shaft 133 continue to be raised. At this time, the position of the second hinge 12 can be higher than the edge of the boss of the first hinge 11, so that the second hinge 12 will not be hindered by the edge of the boss of the first hinge 11, and the second hinge 12 can continue to rotate. Since the second rotating shaft 133 is rotatably connected to the damping member 14 , the second hinge 12 can continue to rotate relative to the first hinge 11 via the second rotating shaft 133 , so that the second hinge 12 can rotate to the unfolded position.

[0071] In this way, the first rotating shaft 131 and the second rotating shaft 133 are both rotatably connected to the damping member 14, so that the positions of the second hinge 12 and the second rotating shaft 133 relative to the first rotating shaft 131 can be raised during the rotation process, which helps to reduce the situation where the boss edge of the first hinge 11 hinders the rotation of the second hinge 12, thereby helping to ensure the smooth rotation of the second hinge 12 and also helping to increase the opening and closing angle of the second hinge 12 relative to the first hinge 11.

[0072] Please also read Figures 11 to 13 In some embodiments, the deformation notch 147 may include a first deformation notch 1442 and a second deformation notch 1452 , the first rotation shaft through hole 1441 is connected to the first deformation notch 1442 , and the second rotation shaft through hole 1451 is connected to the second deformation notch 1452 .

[0073] In this way, the first deformation notch 1442 and the second deformation notch 1452 enable the damping part 141 to have the ability to deform. Then, when the first rotating shaft 131 and / or the second rotating shaft 133 and the damping member 14 rotate, the first deformation notch 1442 and / or the second deformation notch 1452 can meet the deformation requirement of the damping part 141, which helps to reduce the contact friction between the first rotating shaft 131 and / or the second rotating shaft 133 and the damping part 141, and helps to reduce the situation where the damping part 141 fails due to excessive friction between the first rotating shaft 131 and / or the second rotating shaft 133 and the damping part 141, thereby helping to extend the service life of the damping member 14.

[0074] In some embodiments, the first deformation notch 1442 and the first rotating shaft 131 define a first oil storage portion 1443, and the second deformation notch 1452 and the second rotating shaft 133 define a second oil storage portion 1453, and the first oil storage portion 1443 and the second oil storage portion 1453 are both structures of the oil storage portion 148. In this way, when the first rotating shaft 131 and the second rotating shaft 133 rotate, the lubricating oil in the hinge structure 100 for lubricating the first rotating shaft 131 and the second rotating shaft 133 will be squeezed and overflow, and the overflowed lubricating oil can be stored in the first oil storage portion 1443 and the second oil storage portion 1453, which helps to reduce the overflowed lubricating oil from flowing to the first hinge 11 or the second hinge 12, thereby helping to reduce the first hinge 11 or the second hinge 12 from being dirty. The lubricating oil in the first oil storage portion 1443 and the second oil storage portion 1453 can also lubricate the first rotating shaft 131, the second rotating shaft 133 and the damping member 14, which helps to extend the lubricating effect time of the lubricating oil on the first rotating shaft 131 and the second rotating shaft 133, and helps to reduce the wear caused by friction and heat between the first rotating shaft 131 and the damping member 14, and between the second rotating shaft 133 and the damping member 14.

[0075] In some embodiments, the deformation groove 149 may include a first deformation groove 1444 and a second deformation groove 1454, wherein the first deformation groove 1444 is connected to the first rotation shaft through hole 1441, and the second deformation groove 1454 is connected to the second rotation shaft through hole 1451. In this way, the first deformation groove 1444 and the second deformation groove 1454 can both meet the deformation requirements of the damping part 141, and when the damping part 141 is deformed through the first deformation groove 1444 and the second deformation groove 1454 respectively, the inner side of the damping part 141 can be deformed to balance the stress of the outer side of the damping part 141, thereby helping to extend the service life of the damping part 141.

[0076] The first deformation groove 1444 and the first rotating shaft 131 form a first gap 1502, and the second deformation groove 1454 and the second rotating shaft 133 form a second gap 1503. The first gap 1502 and the second gap 1503 can respectively provide deformation space for the damping part 141. The first gap 1502 and the second gap 1503 can also store the lubricating oil overflowed from the first rotating shaft 131 and the second rotating shaft 133, which helps to reduce the overflow of the lubricating oil from both ends of the first rotating shaft 131 and the second rotating shaft 133, thereby helping to reduce the dirtiness of the hinge structure 100.

[0077] See also Fig.13In some embodiments, the hinge structure 100 may further include a first linkage member 151 and a second linkage member 152, both of which are mounted on the first rotating shaft 131 and the second rotating shaft 133, and the first rotating shaft 131 and the second rotating shaft 133 are rotatably connected to the first linkage member 151 and the second linkage member 152, and a plurality of damping members 14 are located between the first linkage member 151 and the second linkage member 152.

[0078] In this way, the first linkage member 151 and the second linkage member 152 can connect the first rotating shaft 131 and the second rotating shaft 133, and the first linkage member 151 and the second linkage member 152 can also limit the axial movement of multiple damping members 14 along the first rotating shaft 131, which helps to reduce the situation where the damping members 14 fall off from the ends of the first rotating shaft 131 and / or the second rotating shaft 133.

[0079] In addition, the first linking member 151 and the second linking member 152 also help maintain the position distance between the multiple damping members 14, so that the multiple damping members 14 can be relatively fixedly located on the periphery of the first rotating shaft 131 and the second rotating shaft 133, thereby helping to reduce the movement of the damping members 14 and helping to reduce the damping members 14 from falling off from the first deformation notch 1442 and / or the second deformation notch 1452.

[0080] Re-read Fig. 9 and Fig.10 In some embodiments, the hinge structure 100 may further include a protective member 17, which is sleeved on the outer sides of the plurality of damping members 14. In this way, the protective member 17 may limit the radial movement of the plurality of damping members 14 along the first rotating shaft 131, thereby helping to reduce the possibility of the damping members 14 falling off from the first rotating shaft 131 and / or the second rotating shaft 133.

[0081] In addition, the protective member 17 can also provide certain protection for the first oil storage portion 1443 and the second oil storage portion 1453, which helps to reduce the leakage of lubricating oil caused by the first oil storage portion 1443 and the second oil storage portion 1453 being exposed, and helps to reduce the waste of resources.

[0082] Re-read Figure 6 In some embodiments, the hinge structure 100 may further include a filling member 18, which is sleeved on the first rotating shaft 131 and is located between the damping member 14 and the first hinge 11 and the second hinge 12; or, the filling member 18 is located between two adjacent damping members 14. In this way, the filling member 18 can fill the gap between the damping member 14 and the first hinge 11 and the second hinge 12 or the gap between two adjacent damping members 14, so that the multiple damping members 14 can be relatively fixedly located on the first rotating shaft 131, thereby helping to reduce the movement of the damping members 14 and helping to ensure the damping effect of the multiple damping members 14.

[0083] Exemplarily, when the friction force between the first rotating shaft 131 of the hinge structure 100 and the damping member 14 is greater than the required friction force, the friction force between the first rotating shaft 131 and the damping member 14 can be reduced by reducing an appropriate number of damping members 14 on the first rotating shaft 131 and adding a filling member 18 to fill the gap of the reduced damping member 14; when the friction force between the first rotating shaft 131 of the hinge structure 100 and the damping member 14 is less than the required friction force, the filling member 18 can be removed and an appropriate number of damping members 14 can be added to the gap of the filling member 18 to increase the friction force between the first rotating shaft 131 and the damping member 14.

[0084] In summary, the hinge structure 100 provided by the embodiment of the utility model, the first hinge 11 and the second hinge 12 of the hinge structure 100 are rotatably connected through the first rotating shaft 131. A plurality of damping members 14 are sleeved on the first rotating shaft 131, and the plurality of damping members 14 are stacked along the length direction of the first rotating shaft 131, so that the plurality of damping members 14 can provide friction for the first rotating shaft 131. In this way, the number of damping members 14 sleeved on the first rotating shaft 131 can be selectively adjusted to adjust the length of the damping member 14 sleeved on the first rotating shaft 131, thereby changing the friction between the first rotating shaft 131 and the damping member 14, which helps to improve the adjustability of the friction between the first rotating shaft 131 and the damping member 14, and also helps to improve the adaptability of the plurality of damping members 14 and the first rotating shaft 131, which helps to reduce the waste of resources.
