Description

Technical Field

[0001] The embodiments of the present application relate to the field of electronic devices, and in particular to an elastic member, a rotating structure and a foldable electronic device. Background Art

[0002] Foldable electronic devices have become a major trend, including foldable mobile phones, laptops, foldable tablets, etc. Foldable electronic devices usually need to use a rotating structure to open the two parts to a certain angle, and can maintain the angle between the two parts stable after unloading.

[0003] At present, the rotation structure usually adopts the cooperation of cam and concave wheel to provide rotation resistance, so that the foldable electronic device can maintain the angle between the two parts unchanged without external force. In addition, elastic members are usually used to provide elastic force to make the cam and concave wheel press tightly. However, common elastic members, such as springs and / or disc springs, have problems of low assembly efficiency and large assembly error between the cam and the concave wheel. Utility Model Content

[0004] The embodiments of the present application provide an elastic member, a rotating structure and a foldable electronic device, which are used to solve the problems of low assembly efficiency and large assembly error between common elastic members and cams and concave wheels.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an elastic member is provided. The elastic member is applied to a rotating structure, and the rotating structure includes a rotating shaft and a first matching member sleeved on the rotating shaft. The first matching member forms a first structure.

[0007] The elastic member is provided with a through hole, and the elastic member is sleeved on the rotating shaft by using the through hole. The elastic member includes an integrally formed elastic part and a second matching part, and the second matching part is located at the end of the elastic part along the extension direction of the through hole. The elastic part includes at least two elastic arms, and the at least two elastic arms are distributed along the extension direction of the through hole, and two adjacent elastic arms are connected to each other and surround a connecting hole. The second matching part is formed with a second structure, and the second structure is used to abut against the first structure.

[0008] One of the first matching piece and the second matching piece rotates relative to the rotation axis, and when the first structure and the second structure rotate, the second matching piece slides on the rotation axis along the extension direction of the through hole. One of the first structure and the second structure includes a protrusion and the other includes a groove.

[0009] The second matching piece is directly arranged at the end of the elastic part of the elastic part, and the second structure on the second matching piece cooperates with the first structure of the first matching piece, so that the elastic part and the second matching piece are integrally formed without assembly. The elastic part in the elastic part of the present application can replace the spring and the disc spring. Compared with the scheme of the spring and the disc spring, the elastic part and the second matching piece can be installed on the rotating shaft at one time, which improves the assembly efficiency of the rotating structure and reduces the assembly error between the elastic part and the second matching piece. The elastic part will not cause wear to the end face of the second matching piece during the deformation process. Secondly, compared with the scheme that the disc spring assembly needs to be installed piece by piece, the present application can realize the elastic deformation of the elastic part by arranging connected elastic arms on the elastic part, and each elastic arm is integrally formed without assembly, which improves the assembly efficiency of the rotating structure. In addition, the elastic part in the present application can improve the consistency of the elastic part by controlling the wall thickness of the elastic arm to be consistent during the processing.

[0010] In a possible implementation of the first aspect, the connecting hole includes a first opening area and a second opening area that are connected to each other; the size of the first opening area in the extension direction of the through hole gradually increases along the direction approaching the second opening area; the size of the second opening area in the extension direction of the through hole gradually increases along the direction approaching the first opening area.

[0011] In this way, the connection hole can be prismatic, increasing the area of ​​the connection hole, allowing the elastic part to have a larger deformation amount, being easier to be compressed, and being able to meet a larger elasticity requirement. In addition, the dimension of the elastic arm along the extension direction of the through hole is increased, improving the structural strength of the elastic part.

[0012] In a possible implementation of the first aspect, the elastic arm includes a first connecting surface opposite to the first opening area, and the angle between the first connecting surface and the plane perpendicular to the extension direction of the through hole is A, 0°≤A≤30°. A can be 5°, 10°, 15°, 20°, 25° or 30°. In the case of 0°≤A≤30°, a larger elasticity requirement can be met, and a higher rigidity can be maintained, and the elastic arm is not easy to break.

[0013] In a possible implementation of the first aspect, the elastic arm includes a second connecting surface opposite to the second opening area, and the angle between the second connecting surface and the plane perpendicular to the extension direction of the through hole is B, 0°≤B≤30°. B can be 5°, 10°, 15°, 20°, 25° or 30°. In the case of 0°≤B≤30°, a larger elasticity requirement can be met, and a higher rigidity can be maintained, and the elastic arm is not easy to break.

[0014] In a possible implementation of the first aspect, the connection hole further includes a third opening area, one end of the third opening area is connected to the first opening area, and the other end of the third opening area is connected to the second opening area. The connection hole may be hexagonal, in which case the position of the third opening area is the position where the connection hole has the largest size along the extension direction of the through hole.

[0015] In a possible implementation of the first aspect, the third opening area includes a first sub-opening area, and a second sub-opening area and a third sub-opening area connected to both ends of the first sub-opening area, the second sub-opening area is connected to the first opening area, and the size of the second sub-opening area in the extension direction of the through hole gradually increases along the direction close to the first opening area; the third sub-opening area is connected to the second opening area, and the size of the third sub-opening area in the extension direction of the through hole gradually increases along the direction close to the second opening area. Compared with the third opening area being linear, the third opening area includes the first sub-opening area, the second sub-opening area and the third sub-opening area, which increases the size of each elastic arm along the extension direction of the through hole and improves the structural strength of the elastic part.

[0016] In a possible implementation of the first aspect, center lines of two adjacent connection holes are located on the same straight line, wherein the center lines of the connection holes are parallel to the extension direction of the through holes, which facilitates processing and improves production efficiency.

[0017] In a possible implementation of the first aspect, center lines of two adjacent connecting holes along the extension direction of the through hole are staggered, wherein the center line of the connecting hole is parallel to the extension direction of the through hole, so that the force on the elastic arm is more uniform, thereby improving the structural stability of the elastic part.

[0018] In a possible implementation of the first aspect, the end position of the connecting hole along the extension direction perpendicular to the through hole is an arc-shaped structure to reduce stress concentration when the edge position is deformed, avoid fracture at the edge position due to stress concentration, and extend the service life of the elastic part.

[0019] In the second aspect, a rotation structure is also provided, which includes a first bracket, a second bracket, a rotation shaft, a first matching piece and the elastic piece as described above, wherein the first bracket is fixedly connected to the rotation shaft, the first matching piece is sleeved on the rotation shaft, the second bracket is connected to the first matching piece to rotate around the rotation shaft, the elastic piece is sleeved on the rotation shaft, and the second matching piece of the elastic piece abuts against the first matching piece; when the first matching piece and the second matching piece rotate in position, the second matching piece slides on the rotation shaft along the extension direction of the through hole.

[0020] Since the rotating structure provided in the present application includes the elastic member of any technical solution of the first aspect mentioned above, the two can solve the same technical problem and achieve the same effect.

[0021] The rotating structure also includes a friction plate between the first bracket and the first matching piece, the friction plate is sleeved on the rotating shaft and abuts against the first matching piece. By setting the friction plate to rub against the side of the first matching piece away from the second matching piece, the rotation resistance between the first bracket and the second bracket is further increased.

[0022] In a third aspect, the foldable electronic device includes a first shell, a second shell, and the rotating structure as described above, wherein the first shell is connected to the first bracket, and the second shell is connected to the second bracket.

[0023] Since the foldable electronic device provided in the present application includes the rotating structure of any technical solution of the second aspect mentioned above, the two can solve the same technical problem and achieve the same effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] In the embodiments of the present application, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0045] In the embodiments of the present application, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0046] The embodiment of the present application provides a foldable electronic device. The foldable electronic device may be a foldable mobile phone, a wearable device, a vehicle-mounted device, an augmented reality (AR) / virtual reality (VR) device, a laptop, an ultra-mobile personal computer (UMPC), a netbook, a personal digital assistant (PDA) and other mobile terminals, or may also be a digital camera, a SLR camera / micro-single camera, a sports camera, a PTZ camera, a drone and other professional shooting equipment. The embodiment of the present application does not limit the specific type of the foldable electronic device. For ease of understanding, the foldable electronic device is described below as a foldable mobile phone.

[0047] See also Figure 1 , the foldable electronic device 100 is approximately in the shape of a rectangular flat plate in the unfolded state. In order to facilitate the description of each embodiment below, an XYZ coordinate system is established for the foldable electronic device 100 in the unfolded state, and the length direction of the foldable electronic device 100 is defined as the X-axis direction, the width direction of the foldable electronic device 100 is defined as the Y-axis direction, and the thickness direction of the foldable electronic device 100 is defined as the Z-axis direction.

[0048] It is understandable that the coordinate system of the foldable electronic device 100 can be flexibly set according to actual needs, and no specific limitation is made here. In some other embodiments, the shape of the foldable electronic device 100 can also be a square flat plate, a circular flat plate, an elliptical flat plate, etc.

[0049] The foldable electronic device 100 may include a foldable screen 10, a support device 20, and a rotating structure 30. For ease of description, the embodiments of the present application are all described by taking the foldable device 100 as an inner-folding foldable device as an example, and it should be understood that an outer-folding foldable device also belongs to the protection scope of the present application.

[0050] The folding screen 10 includes a first display portion 11, a second display portion 12 and a third display portion 13, and the third display portion 13 is connected between the first display portion 11 and the second display portion 12. The user can unfold the folding screen to expose the first display portion 11, the second display portion 12 and the third display portion 13 to present images, videos and other information to the user.

[0051] exist Figure 1In the foldable electronic device 100 shown, the foldable screen 10 is in an unfolded state, and the first display unit 11, the third display unit 13, and the second display unit 12 are arranged in sequence along the X-axis direction. At this time, the foldable electronic device 100 can be folded along the X-axis direction.

[0052] In some other embodiments, when the folding screen 10 is in the unfolded state, the first display unit 11, the third display unit 13, and the second display unit 12 may also be arranged in sequence along the Y-axis direction. At this time, the foldable electronic device 100 can be folded along the Y-axis direction. When the folding screen 10 is in the unfolded state, a large screen display can be achieved to provide users with richer information and bring users a better user experience.

[0053] At least the third display portion 13 of the folding screen 10 is a flexible screen structure, so that the third display portion 13 can be bent and deformed after being subjected to an external force, so that the folding screen 10 switches from the unfolded state to the folded state. The first display portion 11 and the second display portion 12 of the folding screen 10 can be a flexible screen structure, or a rigid screen structure, or a part can be a flexible screen structure and the other part can be a rigid screen structure, which is not specifically limited in this application.

[0054] See also Figure 2 , Figure 2 The foldable electronic device 100 is in a folded state, and the foldable screen 10 in the foldable electronic device 100 is also in a folded state. Exemplarily, when the foldable screen 10 is in a folded state, the first display portion 11 and the second display portion 12 of the foldable screen 10 are approximately parallel and opposite. It should be noted that if the angle between the first display portion 11 and the second display portion 12 is within 30°, it can be considered that the first display portion 11 and the second display portion 12 are approximately parallel.

[0055] When the foldable screen 10 is in the folded state, the third display portion 13 can be folded into a water drop shape. It is understandable that when the foldable electronic device 100 is in the folded state, the third display portion 13 of the foldable screen 10 can also be folded into other shapes according to actual needs, and this application does not limit this.

[0056] When the foldable electronic device 100 is in the folded state, the support device 20 is located outside the foldable screen 10, and the foldable screen 10 is invisible to the user, which can prevent the foldable screen 10 from being scratched by hard objects. When the foldable electronic device 100 is in the folded state, the size of the foldable electronic device 100 along the X-axis direction is reduced, which is convenient to carry.

[0057] See also Figure 3, the support device 20 is used to carry the folding screen 10. The support device 20 may include a first shell 21 and a second shell 22. The first shell 21 carries the first display unit 11, and the second shell 22 carries the second display unit 12. The rotating structure 30 is connected between the first shell 21 and the second shell 22. In addition, the rotating structure 30 is arranged corresponding to the third display unit 13. The rotating structure 30 can be connected to the second shell 22 and the first shell 21 respectively, and is used to realize the rotation between the second shell 22 and the first shell 21, so as to support the folding screen 10 to switch between the unfolded state and the folded state.

[0058] See also Figure 4 The rotating structure 30 may include a first bracket 31, a second bracket 32 ​​and a rotating shaft 38. The first bracket 31 may be used to connect the first shell, and the second bracket 32 ​​may be used to connect the second shell. The rotating shaft 38 includes a first rotating shaft 33 and a second rotating shaft 34 extending along the Y-axis direction, the first rotating shaft 33 and the second rotating shaft 34 are arranged at intervals along the X-axis direction, and the first rotating shaft 33 and the second rotating shaft 34 are arranged in parallel.

[0059] Please refer to Figure 5 , the first bracket 31 may include a first main body portion 313, a first assembly portion 314 and a first mounting portion 315. The first main body portion 313 extends along the Y-axis direction, the first assembly portion 314 extends along the X-axis direction, the first assembly portion 314 is connected to the first main body portion 313, and the first assembly portion 314 is used to connect the first shell. The number of the first assembly portions 314 may be one, two, three or other numbers, and the present application does not limit the number of the first assembly portions 314. In this embodiment, the number of the first assembly portions 314 is described as two, and the two first assembly portions 314 are respectively connected to the two ends of the first main body portion 313 along the Y-axis direction.

[0060] The first mounting portion 315 extends along the X-axis direction, and the first mounting portion 315 is located on a side of the first main body 313 away from the first assembly portion 314. The first mounting portion 315 is connected to the first main body 313. The first rotating shaft 33 extends along the Y-axis direction, and the first mounting portion 315 is rotatably mounted on the first rotating shaft 33, so that the first bracket 31 can rotate around the first rotating shaft 33. The number of the first mounting portions 315 can also be one, two, three or other numbers, and the present application does not limit the number of the first mounting portions 315. This embodiment is described with the number of the first mounting portions 315 being two, and the two first mounting portions 315 are respectively connected to the two ends of the first main body 313 along the Y-axis direction. The two first assembly portions 314 are arranged one-to-one with the two first mounting portions 315, and the first assembly portion 314 and the corresponding first mounting portion 315 are respectively connected to the two ends of the first main body 313 along the X-axis direction. That is, the first main body portion 313 , the two first assembly portions 314 and the two first installation portions 315 form an “H”-shaped structure, so that the first bracket 31 has a stable structure and is evenly stressed.

[0061] Please refer to Figure 6 , referring to the above, the second bracket 32 ​​may include a second main body 322, a second assembly part 323 and a second mounting part 324. The second main body 322 extends along the Y-axis direction, the second assembly part 323 extends along the X-axis direction, the second assembly part 323 is connected to the second main body 322, and the second assembly part 323 is used to connect the second shell. The number of second assembly parts 323 can be one, two, three or other numbers, and the present application does not limit the number of second assembly parts 323. In this embodiment, the number of second assembly parts 323 is two for description, and the two second assembly parts 323 are respectively connected to the two ends of the second main body 322 along the Y-axis direction.

[0062] The second mounting portion 324 extends along the X-axis direction, and the second mounting portion 324 is connected to the second main body 322. The second rotating shaft 34 extends along the Y-axis direction, and the second mounting portion 324 is rotatably sleeved on the second rotating shaft 34, so that the second bracket 32 ​​can rotate around the second rotating shaft 34. The number of the second mounting portions 324 can also be one, two, three or other numbers, and the present application does not limit the number of the second mounting portions 324. This embodiment is described with the number of the second mounting portions 324 being two, and the two second mounting portions 324 are respectively connected to the two ends of the second main body 322 along the Y-axis direction. The two second assembly portions 323 are arranged one-to-one with the two second mounting portions 324, and the second assembly portion 323 and the corresponding second mounting portion 324 are respectively connected to the two ends of the second main body 322 along the X-axis direction. In other words, the second main body 322, the two second assembly portions 323 and the two second mounting portions 324 constitute an "H"-shaped structure, so that the structure of the second bracket 32 ​​is stable and the force is uniform.

[0063] In this embodiment, the second bracket 32 ​​has the same structure as the first bracket 31. In other embodiments, the second bracket 32 ​​may also have a different structure from the first bracket 31.

[0064] See also Figure 7 The rotating structure 30 may further include a first damping assembly 36 and a second damping assembly 37. When the first bracket 31 rotates around the first rotating shaft 33, the first damping assembly 36 generates resistance to hinder the rotation of the first bracket 31. When the second bracket 32 ​​rotates around the second rotating shaft 34, the second damping assembly 37 generates resistance to hinder the rotation of the second bracket 32. The rotating structure 30 generates rotation resistance to the first bracket 31 and the second bracket 32 ​​by providing the first damping assembly 36 and the second damping assembly 37, so that the angle between the first shell and the second shell can be kept unchanged without the action of external force, so that the foldable electronic device can be folded and hovered, so that the use of the foldable electronic device is more convenient.

[0065] The first damping assembly 36 may include a first matching member 361a and a first friction member 362a, and the number of the first matching member 361a and the first friction member 362a may be one. The first matching member 361a is located between the two first mounting portions 315, and the first matching member 361a is connected to one of the first mounting portions 315. The first matching member 361a is sleeved on the first rotating shaft 33, and the first matching member 361a is rotatably connected to the first rotating shaft 33, so that the first bracket 31 can rotate around the first rotating shaft 33.

[0066] The first friction member 362a is sleeved on the first rotating shaft 33, and the first friction member 362a is located between the first matching member 361a and another first mounting portion 315. The first friction member 362a and the first matching member 361a are in contact with each other to rotate, and the first friction member 362a is used to increase the resistance of the first matching member 361a during rotation, thereby increasing the resistance of the first bracket 31 to rotation. Exemplarily, one of the first friction member 362a and the first matching member 361a can be a cam, and the other can be a concave wheel, and the cam and the concave wheel cooperate to provide resistance during rotation.

[0067] The first friction member 362a cannot rotate around the first rotating shaft 33, and the first friction member 362a can slide with the first rotating shaft 33 along the Y-axis direction. That is, when the first matching member 361a rotates relative to the first friction member 362a, the concave wheel and the cam squeeze each other, and a thrust in the Y-axis direction is applied to the first friction member 362a. The first friction member 362a can slide relative to the first rotating shaft 33 along the Y-axis direction, which can avoid the first matching member 361a from being stuck, thereby improving the reliability of the rotation of the first bracket 31.

[0068] The first damping assembly 36 may further include a first spring 363a, which extends along the Y-axis direction, is sleeved on the first rotating shaft 33, and abuts between the first friction member 362a and the first mounting portion 315. The first spring 363a may be in a compressed state, and the elastic force generated by the first spring 363a causes the first friction member 362a to have a pressure close to the first matching member 361a, so that the abutting pressure between the first friction member 362a and the first matching member 361a is increased, and the abutment is tighter, thereby increasing the friction between the first friction member 362a and the first matching member 361a, so as to increase the rotation resistance when the first bracket 31 rotates.

[0069] When the first bracket 31 rotates, the first mating piece 361a and the first friction piece 362a squeeze each other, and the first mating piece 361a pushes the first friction piece 362a to move away from the first mating piece 361a, so that the compression of the first spring 363a increases, and the elastic force of the first spring 363a increases, thereby increasing the abutment pressure between the first friction piece 362a and the first mating piece 361a, so that when the first bracket 31 rotates, the first friction piece 362a can maintain abutment with the first mating piece 361a, and can provide stable rotation resistance.

[0070] When the first bracket 31 rotates, the first matching piece 361a and the first friction piece 362a are pressed against each other, and the elastic force of the first spring 363a pushes the first friction piece 362a to move along the Y-axis and in the direction close to the first matching piece 361a, and the compression amount of the first spring 363a is reduced, which helps the first friction piece 362a to reset.

[0071] like Figure 7 As shown, the number of the first mating parts 361a and the first friction parts 362a can also be two, the two first mating parts 361a are respectively connected to the two first mounting parts 315, and the two first friction parts 362a are respectively matched with the two first mating parts 361a in a one-to-one manner. At this time, the first spring 363a abuts between the two first friction parts 362a.

[0072] As mentioned above, the second damping assembly 37 may include a first matching member 361b, a first friction member 362b and a first spring 363b. The matching relationship between the second damping assembly 37 and the second bracket 32 ​​and the second rotating shaft 34 may refer to the first damping assembly 36, which will not be repeated here.

[0073] Exemplarily, the first friction member 362a is sleeved on the first rotating shaft 33, and the first friction member 362b is sleeved on the second rotating shaft 34. The first friction member 362a and the first friction member 362b can be connected to each other so that the first friction member 362a and the first friction member 362b restrict each other, so that the first friction member 362a cannot rotate around the first rotating shaft 33, and the first friction member 362b cannot rotate around the second rotating shaft 34.

[0074] See also Figure 7 The rotating structure 30 may further include a retaining spring 35, and the first rotating shaft 33 and the second rotating shaft 34 may be connected by the retaining spring 35. The first rotating shaft 33 and the second rotating shaft 34 are respectively sleeved in two holes of the retaining spring 35, and the sizes of the two holes are respectively matched with the sizes of the first rotating shaft 33 and the second rotating shaft 34. By providing the retaining spring 35, the relative position between the first rotating shaft 33 and the second rotating shaft 34 can be fixed, which is conducive to ensuring the axis distance between the first rotating shaft 33 and the second rotating shaft 34.

[0075] In the above scheme, the elastic force of the first spring 363 in a compressed state is used to apply a thrust along the Y-axis direction and away from the first spring 363 to the first friction member 362. However, the first spring 363 and the first friction member 362 need to be assembled, which will cause assembly errors. In addition, during the deformation of the first spring 363, the first spring 363 will cause wear on the end surface of the first friction member 362. Similarly, the second spring 373 and the second friction wheel 372 also need to be assembled, which will also cause assembly errors. During the deformation of the second spring 373, the second spring 373 will also cause wear on the end surface of the second friction wheel 372.

[0076] In other schemes, a disc spring assembly is used to replace the first spring and the second spring, and the disc spring assembly includes multiple disc springs. The specific number of disc springs depends on the axial (i.e., Y-axis direction) elastic force required by the actual product. Each disc spring has a front side and a back side. The front side of one disc spring and the back side of another disc spring are butt-jointed and assembled between two adjacent disc springs. Multiple disc springs are assembled to form an integral sleeve on the first rotating shaft or the second rotating shaft. Therefore, multiple disc springs need to be distinguished from the front and back and assembled in sequence. Manual assembly is inefficient and prone to errors. It is necessary to distinguish the front and back one by one and pinch them into place. When the number of disc springs required is large, the assembly efficiency of the disc spring assembly is low and it is more likely to make assembly errors. In addition, the disc spring and the first friction member 362 and the second friction wheel 372 also need to be assembled, and the assembly error will be greater. In addition, due to the manufacturing process, each disc spring may have differences in size and morphology, resulting in poor consistency in stiffness / elastic strength of the disc spring, resulting in obvious overall differences after assembly, uneven yield levels, and large differences in consistency experience of the same product.

[0077] See also Figure 8 In order to solve the problem of assembly error caused by the above-mentioned spring and disc spring, the present application provides an elastic member 40. The elastic member 40 is used for the rotating structure 30. The rotating structure 30 includes a first matching member 361 and a rotating shaft 38. The first matching member 361 includes the above-mentioned first matching member 361a and the first matching member 361b. The rotating shaft 38 includes the above-mentioned first rotating shaft 33 and the second rotating shaft 34. For the convenience of description, the first matching member 361 in the following text is described by taking the first matching member 361a as an example, and the rotating shaft 38 is described by taking the first rotating shaft 33 as an example.

[0078] The first matching member 361a is rotatably mounted on the first rotating shaft 33. The elastic member 40 is mounted on the first rotating shaft 33, and the elastic member 40 is used to cooperate with the first matching member 361a to generate rotation resistance, so that the angle between the first shell and the second shell can be kept unchanged without external force, so that the foldable electronic device can be folded and suspended, making the use of the foldable electronic device more convenient.

[0079] Please refer to Fig. 9 In some embodiments, the elastic member 40 is provided with a through hole 41 ( Fig. 9 The through hole 41 penetrates the elastic member 40 along the Y-axis direction. The first rotating shaft 33 can be inserted into the through hole 41, so that the elastic member 40 can be sleeved on the first rotating shaft 33 using the through hole 41. The cross section of the through hole 41 can be circular, square or polygonal, and the through hole 41 can match the shape of the first rotating shaft 33. The present application does not limit the shape of the through hole 41. For example, when the cross section of the through hole 41 is circular, the elastic member 40 can be a cylindrical structure.

[0080] The elastic member 40 includes an integrally formed elastic portion 42 and a second matching member 43. The elastic portion 42 extends along the Y-axis direction, and the second matching member 43 is located at the end of the elastic portion 42 along the extension direction of the through hole 41, that is, the Y-axis direction. The elastic portion 42 is made of an elastic material, and the elastic material can be plastic, rubber, or an elastic metal material. The present application does not limit the specific material of the elastic portion 42. Under the action of a force along the Y-axis direction, the elastic portion 42 can be elastically deformed along the Y-axis direction.

[0081] The elastic part 42 includes at least two elastic arms 421, and the at least two elastic arms 421 are distributed along the extension direction (i.e., the Y-axis direction) of the through hole 41. The local positions of two adjacent elastic arms 421 are connected, so that the two adjacent elastic arms 421 surround a connecting hole 422. The elastic part 42 is compressed under the action of the force along the Y-axis direction, and the size of the connecting hole 422 in the Y-axis direction will become smaller. By forming the connecting hole 422, the compression degree of the elastic part 42 can be increased, and the compression amount of the elastic part 42 is increased, thereby increasing the elastic force of the elastic part 42.

[0082] The second mating piece 43 is connected to the end of the elastic part 42. The second mating piece 43 is formed with a second structure 431, and the second structure 431 is arranged toward the first mating piece 361a. The first mating piece 361a is formed with a first structure 50 facing the second mating piece 43. The second structure 431 is used to abut against the first structure 50, and one of the first structure 50 and the second structure 431 includes a protrusion and the other includes a groove. In this embodiment, the second structure 431 includes a protrusion and the first structure 50 includes a groove as an example for description.

[0083] The second structure 431 matches the shape of the first structure 50 . The second structure 431 is used to abut against the first structure 50 . When the second structure 431 abuts against the first structure 50 , it is pushed by the first structure 50 so that the elastic part 42 is in a compressed state.

[0084] It can be understood that when the second structure 431 cooperates with the first structure 50 , it is simultaneously subjected to a thrust force applied by the first structure 50 in a direction close to the elastic portion 42 and an elastic force applied by the elastic portion 42 in a direction close to the first structure 50 .

[0085] The second structure 431 is in contact with the first structure 50. By arranging the second structure 431 to cooperate with the first structure 50, the contact area between the second mating piece 43 and the first mating piece 361a is increased, and the rotation resistance provided by the first damping assembly and the second damping assembly is increased. When the second structure 431 and the first structure 50 are arranged, they are generally arranged as arc-shaped protrusions, and correspondingly, the corners of the opening edge of the first structure 50 are also arc-shaped. When the first mating piece 361a rotates, the second structure 431 can slide relative to the first structure 50 and slide out of the first structure 50, so as to prevent the second structure 431 from being stuck in the first structure 50.

[0086] See also Fig. 9When the first bracket 31 rotates relative to the second bracket 32, the first bracket 31 can drive the first matching piece 361a to rotate because the first bracket 31 is fixedly connected to the first matching piece 361a. The first structure 50 on the first matching piece 361a and the second structure 431 on the second matching piece 43 abut against each other and rotate. The first matching piece 361a pushes the second matching piece 43 to slide along the Y axis and in the direction close to the elastic part 42, and the second structure 431 on the second matching piece 43 slides out from the first structure 50. At this time, the second mating piece 43 squeezes the elastic part 42, and the end of the elastic part 42 connected to the second mating piece 43 is subjected to a force along the Y-axis and away from the first mating piece 361, so that the compression amount of the elastic part 42 increases, and the elastic force applied by the elastic part 42 to the second mating piece 43 along the Y-axis and close to the first mating piece 361a is increased, thereby increasing the abutment pressure between the second mating piece 43 and the first mating piece 361a, so that when the first bracket 31 rotates relative to the second bracket 32, the second mating piece 43 can maintain abutment with the first mating piece 361a, and can provide stable rotation resistance.

[0087] When the first bracket 31 rotates in the opposite direction relative to the second bracket 32, the first bracket 31 drives the first matching piece 361a to rotate, the first structure 50 on the first matching piece 361a and the second structure 431 on the second matching piece 43 abut against each other and rotate, the first matching piece 361a pushes the second matching piece 43 to slide along the Y axis and in the direction away from the elastic part 42, and the second structure 431 on the second matching piece 43 slides into the first structure 50. At this time, the force of the second matching piece 43 squeezing the elastic part 42 becomes smaller, and the elastic part 42 has an elastic force along the Y axis and in the direction close to the first matching piece 361a. The elastic force of the elastic part 42 pushes the second matching piece 43 to slide along the Y axis and in the direction close to the first matching piece 361a, so as to help the second structure 431 on the second matching piece 43 slide into the first structure 50, and the compression amount of the elastic part 42 is reduced, and the compression amount of the elastic part 42 can be restored to the initial value. That is to say, when the first bracket 31 rotates in the opposite direction relative to the second bracket 32 ​​, the elastic force of the elastic portion 42 can help the second structure 431 on the second matching member 43 to slide back into the first structure 50 to achieve reset.

[0088] Exemplarily, the elastic portion 42 and the second mating piece 43 may be an integrally formed part, and the elastic portion 42 and the second mating piece 43 may be integrally formed by injection molding, die casting, computer numerically controlled precision machining (Computer numerical control, CNC) or other processes.

[0089] The elastic member 40 in the embodiment of the present application directly sets the second matching member 43 at the end of the elastic part 42 along the Y-axis direction. The second structure 431 on the second matching member 43 matches the first structure 50 of the first matching member 361a, and the elastic part 42 and the second matching member 43 are integrally formed without assembly. The elastic part 42 in the elastic member 40 in the embodiment of the present application can replace the spring and the disc spring. Compared with the scheme of the spring and the disc spring, the elastic part 42 and the second matching member 43 can be installed on the rotating shaft 38 at one time, which improves the assembly efficiency of the rotating structure 30 and reduces the assembly error between the elastic part 42 and the second matching member 43. During the deformation process, the elastic part 42 will not cause wear to the end surface of the second matching member 43. Secondly, compared with the scheme that the disc spring assembly needs to be installed piece by piece, the present application can realize the elastic deformation of the elastic member 40 by setting the connected elastic arms 421 on the elastic part 42. Each elastic arm 421 is integrally formed without assembly, which improves the assembly efficiency of the rotating structure. Furthermore, the elastic member 40 in the present application can improve the consistency of the elastic member 40 by controlling the wall thickness of the elastic arm 421 to be consistent during the processing.

[0090] See also Fig.10 In some embodiments, the elastic arm 421 includes a body portion 4211 and a connecting portion 4212, the connecting portion 4212 is consistent with the extension direction of the through hole 41 (i.e., the Y-axis direction), one end of the connecting portion 4212 is connected to the body portion 4211, and the other end of the connecting portion 4212 is connected to the body portion 4211 of the adjacent elastic arm 421. Each elastic arm 421 may include a connecting portion 4212, that is, the number of connecting portions 4212 between two adjacent body portions 4211 may be one, in which case, the body portions 4211 of two adjacent elastic arms 421 and the two end surfaces of the connecting portions 4212 connected thereto along the circumferential direction of the elastic portion 42 (i.e., the plane where the X-axis and the Z-axis are located) form a connecting hole 422. Exemplarily, one side of the body portion 4211a close to the body portion 4211b, one side of the body portion 4211b close to the body portion 4211a, and two end surfaces of the connecting portion 4212 form a connecting hole 422.

[0091] See also Fig.11In (a) and (b) of the figure, in some embodiments, each elastic arm 421 may include two connecting portions 4212, that is, the number of connecting portions 4212 between two adjacent body parts 4211 may be two, and the two connecting portions 4212 are arranged at intervals along the circumference of the elastic member 40 (i.e., the plane where the X-axis and the Z-axis are located). The two connecting portions 4212 separate the connecting hole 422 into a connecting hole 422a and a connecting hole 422b. By arranging two connecting portions 4212 between two adjacent body parts 4211, the connection area of ​​the two adjacent elastic arms 421 is increased, so that the connection between the two adjacent elastic arms 421 is more stable and reliable, and the structural strength of the elastic part 42 can be improved. Exemplarily, one side of the body part 4211a close to the body part 4211b, one side of the body part 4211b close to the body part 4211a, one side of the connecting portion 4212a, and one side of the connecting portion 4212b surround the connecting hole 422a. A surface of the main body 4211a close to the main body 4211b, a surface of the main body 4211b close to the main body 4211a, the other surface of the connecting portion 4212a and the other surface of the connecting portion 4212b form a connecting hole 422b.

[0092] Exemplarily, the two connecting portions 4212 may be symmetrically distributed, so that the force on the elastic portion 42 is more uniform, thereby extending the service life of the elastic portion 42. In other embodiments, the two connecting portions 4212 may also be asymmetrically distributed.

[0093] In other embodiments, each elastic arm 421 may include a plurality of connection parts 4212 according to actual application scenarios, and the number of connection parts 4212 between two adjacent body parts 4211 may be three, four, five, six or other numbers. This further increases the connection area between two adjacent body parts 4211, strengthens the connection strength between two adjacent elastic arms 421, and improves the structural stability of the elastic part 42.

[0094] See also Fig.12 In Figures (a) and (b), the connection hole 422 includes a first opening area 4221 and a second opening area 4222 connected along the circumference of the elastic part 42 (i.e., the plane where the X-axis and the Z-axis are located), and the size of the first opening area 4221 in the extension direction of the through hole gradually increases along the direction close to the second opening area 4222. The size of the second opening area 4222 in the extension direction of the through hole gradually increases along the direction close to the first opening area 4221. In this way, the connection hole 422 can be prismatic. Compared with the rectangular hole K1, the prismatic connection hole 422 increases the area of ​​the connection hole 422, so that the elastic part 42 can have a larger deformation amount, is easier to be compressed, and can meet a larger elasticity requirement. In addition, compared with the rectangular hole K2, the prismatic connection hole 422 increases the size of the elastic arm 421 along the Y-axis direction, thereby improving the structural strength of the elastic part 42.

[0095] See also Fig.12 In (a) and (b), in some embodiments, the elastic arm 421 includes a first connecting surface 4213 opposite to the first opening area 4221, and the angle between the first connecting surface 4213 and the plane perpendicular to the extension direction of the through hole (i.e., the plane where the X-axis and the Z-axis are located) is A, 0°≤A≤30°, and A can be 5°, 10°, 15°, 20°, 25° or 30°. In the case of 0°≤A≤30°, a larger elasticity requirement can be met, and a higher rigidity can be maintained, and the elastic arm 421 is not easy to break.

[0096] As shown above, the elastic arm 421 includes a second connection surface 4214 opposite to the second opening area 4222, and the angle between the second connection surface 4214 and the plane perpendicular to the extension direction of the through hole (i.e., the plane where the X-axis and the Z-axis are located) is B, 0°≤B≤30°, and B can be 5°, 10°, 15°, 20°, 25° or 30°. In the case of 0°≤B≤30°, a larger elasticity requirement can be met, and a higher rigidity can be maintained, and the elastic arm 421 is not easy to break.

[0097] In some embodiments, A and B may be the same, that is, the first opening area 4221 and the second opening area 4222 are symmetrically arranged along the Y-axis direction, so that the elastic arm 421 is more evenly stressed and the elastic arm 421 is not easily broken. In other embodiments, A and B may be different according to actual needs.

[0098] See also Fig.12 In (a) and (b) of FIG. 4 , in some embodiments, the connection hole 422 may further include a third opening area 4225, one end of the third opening area 4225 is connected to the first opening area 4221, and the other end of the third opening area 4225 is connected to the second opening area 4222. In other words, the connection hole 422 may be hexagonal, and in this case, the position where the third opening area 4225 is located is the position where the connection hole 422 has the largest size along the Y-axis direction.

[0099] See also Fig.13 In (a) and (b), in some embodiments, the third opening area 4225 includes a first sub-opening area 4226, and a second sub-opening area 4227 and a third sub-opening area 4228 connected to both ends of the first sub-opening area 4226. The second sub-opening area 4227 is connected to the first opening area 4221, and the size of the second sub-opening area 4227 in the extension direction of the through hole (i.e., the Y-axis direction) gradually increases along the direction close to the first opening area 4221. The third sub-opening area 4228 is connected to the second opening area 4222, and the size of the third sub-opening area 4228 in the Y-axis direction gradually increases along the direction close to the second opening area 4222.

[0100] See also Fig.13 As can be seen from Figure (b) in FIG. 4, from the first opening area 4221 to the first sub-opening area 4226, the size of the connection hole 422 in the Y-axis direction first increases, then decreases, and then remains unchanged. In other words, the position where the first sub-opening area 4226 is located is the position where the connection hole 422 has the smallest size in the Y-axis direction. Fig.12 In Figures (a) and (b), compared with the third opening area 4225 which is linear, the third opening area 4225 includes a first sub-opening area 4226, a second sub-opening area 4227 and a third sub-opening area 4228, which increases the size of each elastic arm 421 along the Y-axis direction and improves the structural strength of the elastic part 42.

[0101] See also Fig.14 , the center lines of two adjacent connection holes 422 are located on the same straight line, wherein the center line through-hole extension direction (ie, Y-axis direction) of the connection hole 422 is parallel, which facilitates processing and improves production efficiency. Fig.14 Each elastic arm 421 includes two connecting parts 4212, that is, the number of connecting parts 4212 between two adjacent body parts 4211 can be two, and the two connecting parts 4212 are arranged at intervals along the circumference of the elastic member 40 (i.e., the plane where the X-axis and the Z-axis are located). The two connecting parts 4212 separate the connecting hole 422 into a connecting hole 422a and a connecting hole 422b. The center lines of the two adjacent connecting holes 422a along the Y-axis direction are both S1, and the center lines of the two adjacent connecting holes 422b along the Y-axis direction are both S2.

[0102] See also Fig.15 In some embodiments, the center lines of two adjacent connection holes 422 are staggered, wherein the extension direction of the center line through hole of the connection hole 422 (ie, the Y-axis direction) is parallel. Fig.15 As shown, the two connecting parts 4212 separate the connecting hole 422 into a connecting hole 422a and a connecting hole 422b. The center lines of the two connecting holes 422a adjacent to each other along the Y-axis direction are S1 and S2, respectively, and the center lines of the two connecting holes 422b adjacent to each other along the Y-axis direction are S3 and S4, respectively. The center lines of the two connecting holes 422 adjacent to each other along the Y-axis direction are staggered, so that each main body 4211 can be connected to four connecting parts 4212, and the four connections 4212 are spaced apart along the circumference of the elastic part 42 (i.e., the plane where the X-axis and the Z-axis are located). Compared with the parallel arrangement of the center lines of the two connecting holes 422 adjacent to each other along the Y-axis direction, the force on the main body 4211 is more uniform, which can improve the structural stability of the elastic member 40.

[0103] See also Fig.16In some embodiments, the end position of the connecting hole 422 along the extension direction perpendicular to the through hole 41 (i.e., the plane where the X-axis and the Z-axis are located) is an arc-shaped structure to reduce the stress concentration phenomenon when the edge position is deformed, avoid fracture at the edge position due to stress concentration, and extend the service life of the elastic member 40.

[0104] See also Fig.16 In some embodiments, the two ends of the elastic part 42 may further include two connecting cylinders 424, the two connecting cylinders 424 are spaced apart along the Y-axis direction, and the elastic arm 421 is located between the two connecting cylinders 424. One end of the connecting cylinder 424 away from the elastic arm 421 is connected to the second matching piece 43. By providing the connection between the connecting cylinder 424 and the second matching piece 43, the contact area between the elastic part 42 and the second matching piece 43 is increased, so that the connection between the elastic part 42 and the second matching piece 43 is more stable, thereby improving the structural stability of the elastic member 40.

[0105] See also Fig.16 In some embodiments, the two connecting tubes 424 are both connected to the second matching pieces 43, that is, the number of the second matching pieces 43 is two, and the two second matching pieces 43 can respectively match with the two first matching pieces 361a.

[0106] See also Fig.17 In some embodiments, one of the two connecting tubes 424 is connected to the second matching piece 43 , that is, the number of the second matching piece 43 is one.

[0107] See also Fig.18 In some embodiments, the rotating structure 30 can be applied to a laptop computer, that is, the foldable electronic device can be a laptop computer, and the laptop computer includes a keyboard structure and a screen structure. The rotating structure 30 can include a first bracket 31, a second bracket 32, and a rotating shaft 38. The rotating shaft 38 extends along the Y-axis direction. The first bracket 31 is used to connect with the keyboard structure, and the second bracket 32 ​​is used to connect with the screen structure.

[0108] Please refer to Fig.18 and Fig.19 , the first bracket 31 is fixedly connected to one end of the rotating shaft 38. The first bracket 31 can be integrally formed with the rotating shaft 38, reducing the assembly steps between the first bracket 31 and the rotating shaft 38, and improving the assembly efficiency of the rotating structure 30. The first bracket 31 can also be separately formed from the rotating shaft 38, and then the first bracket 31 is fixed to one end of the rotating shaft 38 by welding, bonding or other means, so that the first bracket 31 and the rotating shaft 38 do not rotate relative to each other.

[0109] The first bracket 31 is provided with a first fixing hole 311 penetrating along the Z-axis direction, and a threaded hole can be provided at a position corresponding to the first fixing hole 311 on the keyboard structure, and fixing parts such as bolts or screws can be passed through the first fixing hole 311 and the threaded holes on the keyboard structure to fix the first bracket 31 on the keyboard structure, thereby fixing the first bracket 31 to the keyboard structure.

[0110] The second bracket 32 ​​is provided with a second fixing hole 321 extending through the screen structure in the Z-axis direction. A threaded hole may be provided at a position corresponding to the second fixing hole 321 on the screen structure. Fasteners such as bolts or screws may be passed through the second fixing hole 321 and the threaded hole on the screen structure to fix the second bracket 32 ​​on the screen structure, thereby fixing the second bracket 32 ​​to the screen structure.

[0111] The rotating structure 30 may further include a first matching piece 361, which is rotatably sleeved on the rotating shaft 38. In addition, the first matching piece 361 rotates with the second bracket 32. Exemplarily, a mounting hole 3611 is provided on the first matching piece 361, and the mounting hole 3611 extends along the X-axis direction. The second bracket 32 ​​may further include an extension portion 325, which extends along the X-axis direction, and the extension portion 325 matches the shape of the mounting hole 3611. The extension portion 325 is inserted into the mounting hole 3611, and the extension portion 325 is matched with the mounting hole 3611. The rotation of the extension portion 325 drives the first matching piece to rotate, so that the first matching piece 361 can rotate together with the second bracket 32.

[0112] The rotating structure 30 may also include the elastic member 40, which is provided with a through hole 41, which penetrates the elastic member 40 along the Y-axis direction. The rotating shaft 38 is inserted into the through hole 41, so that the elastic member 40 can be sleeved on the rotating shaft 38. The elastic member 40 may include a connected elastic portion 42 and a second matching member 43, and the elastic portion 42 can be deformed along the extension direction of the through hole 41, so that the second matching member 43 can slide along the extension direction of the through hole 41. In addition, the elastic member 40 cannot rotate around the rotating shaft 38. Exemplarily, the cross-section of the rotating shaft 38 is polygonal, not circular. Please refer to Fig. 20 In (a) and (b) of the figure, the elastic member 40 further includes a stopper 44, which is mounted on the hole wall of the through hole 41 and extends inwardly in a direction perpendicular to the through hole 41. The stopper 44 and the hole wall of the through hole 41 form a first positioning hole 45, and the first positioning hole 45 matches the shape of the rotating shaft 38. The rotating shaft 38 is inserted into the first positioning hole 45, so that the elastic member 40 cannot rotate around the rotating shaft 38. The stopper 44 can be set on the connecting tube 424, which is convenient for installation and will not interfere with the deformation of the elastic part 42.

[0113] Please refer to Fig.18 and Fig.19 The second matching piece 43 is formed with a second structure 431, and the first matching piece 361 is formed with a first structure 50. The second structure 431 is used to match with the first structure 50, and the second structure 431 matches the shape of the first structure 50 on the first matching piece 361. When the elastic piece 40 rotates, the second structure 431 and the first structure 50 are in a separated state or abutted state. By setting the second structure 431 to match with the first structure 50, the contact area between the second matching piece 43 and the first matching piece 361 is increased, and the rotation resistance is increased.

[0114] Under the action of the force along the Y-axis direction, the elastic part 42 can be elastically deformed along the Y-axis direction. The elastic part 42 can be in a compressed state, so that the second structure 431 and the first structure 50 are more tightly abutted to increase the rotation resistance.

[0115] The rotating structure 30 also includes a clamping member 60, which is fixedly connected to one end of the rotating shaft 38 away from the first bracket 31. The clamping member 60 squeezes the elastic part 42 and limits the elastic part 40 between the first mating part 361 and the clamping member 60, so that the force generated by the elastic part 42 can make the second structure 431 and the first structure 50 abut more tightly.

[0116] Exemplarily, the clamping member 60 may be a nut, and accordingly, at least a portion of the rotating shaft 38 is provided with a threaded section matching the nut, and the threaded section is threadedly connected to the nut. The threaded connection facilitates disassembly and replacement, making the use of the clamping member 60 more flexible and convenient. In addition, the threaded connection has a self-locking function, making the connection between the clamping member 60 and the rotating shaft 38 more stable and reliable.

[0117] When the user rotates the screen structure so that the second bracket 32 ​​and the first bracket 31 rotate relative to each other, the second bracket 32 ​​drives the first matching piece 361 to rotate, and the second structure 431 on the second matching piece 43 and the first structure 50 on the first matching piece 361 abut against each other and rotate in position, and the first matching piece 361 pushes the second matching piece 43 to slide along the Y-axis and in the direction close to the elastic part 42, and the second structure 431 on the second matching piece 43 will slide out of the first structure 50 along the arc on the first structure 50. At this time, the second mating piece 43 squeezes the elastic part 42, and the end of the elastic part 42 connected to the second mating piece 43 is subjected to a force along the Y-axis and away from the first mating piece 361, so that the compression amount of the elastic part 42 increases, and the elastic force applied by the elastic part 42 to the second mating piece 43 along the Y-axis and close to the first mating piece 361 increases, thereby increasing the abutment pressure between the second mating piece 43 and the first mating piece 361, so that when the first bracket 31 rotates relative to the second bracket 32, the second mating piece 43 can maintain abutment with the first mating piece 361, and can provide stable rotation resistance.

[0118] When the user rotates the screen structure so that the second bracket 32 ​​rotates in the opposite direction to the first bracket 31, the second bracket 32 ​​drives the first matching piece 361 to rotate, and the second structure 431 on the second matching piece 43 and the first structure 50 on the first matching piece 361 abut against each other and rotate in position, and the first matching piece 361 pushes the second matching piece 43 to slide along the Y axis and in the direction away from the elastic part 42, and the second structure 431 on the second matching piece 43 will slide back into the first structure 50 along the arc on the first structure 50. At this time, the elastic part 42 has an elastic force along the Y axis and in the direction close to the first matching piece 361, and the elastic force of the elastic part 42 pushes the second structure 431 on the second matching piece 43 to slide back into the first structure 50, and the compression amount of the elastic part 42 decreases until it returns to the initial value.

[0119] Please refer to Fig.18 and Fig.19 In some embodiments, the rotating structure 30 further includes a friction plate 70, which is sleeved on the rotating shaft 38 and located between the first bracket 31 and the first mating piece 361. The friction plate 70 is used to rub against a side of the first mating piece 361 away from the second mating piece 43 to increase the rotation resistance of the first mating piece 361. In addition, the friction plate 70 cannot rotate relative to the rotating shaft 38. Exemplarily, a second positioning hole 71 is provided on the friction plate 70, and the second positioning hole 71 matches the shape of the rotating shaft 38. The cross section of the rotating shaft 38 is a polygon, not a circle. The rotating shaft 38 is inserted into the second positioning hole 71, so that the friction plate 70 cannot rotate around the rotating shaft 38.

[0120] Exemplarily, the first bracket 31 may further include a reinforcing portion 312 , and the cross-section of the reinforcing portion 312 may be consistent with that of an end of the first matching piece 361 away from the elastic piece 40 , thereby increasing the contact area between the first matching piece 361 and the first bracket 31 .

[0121] The friction plate 70 may be located between the reinforcement portion 312 and the first mating piece 361. The first bracket 31 increases the contact area with the friction plate 70 by providing the reinforcement portion 312, so that the friction plate 70 can be more stably installed on the rotating shaft 38. Exemplarily, the surface of the friction plate 70 close to the first mating piece 361 may be provided with friction lines to enhance friction.

[0122] The rotating structure of the present application can also be applied to pivot doors, folding machine pivots, accessory pivot scenarios, etc.

[0123] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0124] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
