[0047] In order to facilitate understanding, the application scenarios to which the embodiments of the present application are applicable are first described below.

[0048] With the public's increasingly high demand for the convenience of intelligent terminals, folding electronic devices are gradually becoming a development trend of future mobile electronic products. The folding electronic device has a large display area in the unfolded state, improving the viewing effect, and the folding electronic device can obtain a small volume in the folded state, facilitating user carrying.

[0049] The folding electronic device usually includes a reversible upper and lower module, for example, a folding smart phone. The unfolding and folding of the folding electronic device is realized by a rotating shaft assembly. The rotating shaft assembly includes a torsion module and a connecting piece connected to one end of the torsion module. The other end of the connecting piece is connected to a display panel. The torsion module includes a hinge base and a rotating piece. The rotating piece is rotationally connected to the hinge base. The rotating piece is connected to the connecting piece to drive the display panel to flip. The rotating piece is provided with a concave-convex wheel in the axial direction. A spring is provided on the hinge base and connected to the concave-convex wheel. The axial spring force of the spring is converted into resistance when the concave-convex wheel rotates, realizing the damping feeling and hovering effect in the unfolding and closing process of the folding electronic device.

[0050] However, the axial spring force of the spring directly acts on the concave-convex wheel. In the case of long-time work of the rotating piece, the surface of the concave-convex wheel is prone to wear.

[0051] The rotating shaft assembly and the intelligent terminal provided in the embodiments of the present application are provided. The rotating shaft assembly includes a hinge base, a rotating piece and a connecting piece. The hinge base extends along a first direction. The rotating piece is rotationally arranged on the hinge base along the first direction. The connecting piece is slidably connected to the rotating piece and can rotate relative to the hinge base through the rotating piece. The connecting piece is provided with a damping structure. The damping structure is provided with a first abutting surface. The rotating piece includes a sliding part extending along a second direction. The first direction is perpendicular to the second direction. The first abutting surface is used to abut against the sliding part. The damping structure can at least apply a resistance to the sliding part through the first abutting surface.

[0052] Here, when the rotating member rotates relative to the hinge base, in the axial direction of the rotating member rotation axis, not only the axial force of the spring of the torsion module in the prior art, but also the force applied by the first abutting surface of the damping structure to the sliding part. The damping structure applies a resistance to the sliding part, bears part of the force of the spring on the concave-convex wheel of the rotating member, disperses the stress on the concave-convex wheel, and in this way, the pressure and friction force borne by the concave-convex wheel are greatly reduced, thereby reducing the speed and degree of wear. In actual use, this means that after a long time of frequent folding and unfolding operations, the concave-convex wheel can still maintain good working condition and will not affect the normal performance of the device due to excessive wear. By reducing the wear and failure risk of the rotating member, the rotating shaft assembly can withstand longer use tests. Prolong the overall service life of the torsion module. By designing the size of the resistance applied by the damping structure to the sliding part, the relative position between the rotating member and the connecting member can be fixed, and the free hovering of the display panel turning angle can be realized, thereby improving the user experience.

[0053] Based on the above-mentioned intelligent terminal and the structure of the rotating shaft assembly on the intelligent terminal, various embodiments of the present application are proposed.

[0054] First embodiment

[0055] As Figures 1 to 4 shown, the present application provides a rotating shaft assembly 10, comprising:

[0056] The hinge base 100 extends along the first direction;

[0057] The rotating member 200 is arranged on the hinge base 100 and can rotate around the first direction;

[0058] The connecting member 300 can be used to fix the display panel 20, and the connecting member 300 can rotate relative to the hinge base 100 through the rotating member 200; The connecting member 300 is provided with a damping structure 400, which can at least apply a resistance to the rotating member 200.

[0059] Optionally, the first direction is the length direction of the hinge base 100, the rotating member 200 is rotationally connected with the hinge base 100, and at least one of the hinge base 100 and the rotating member 200 is provided with a rotating shaft, and the present application does not limit the fixing mode of the connecting member 300 and the display panel 20. Optionally, one display panel 20 is fixed on one connecting member 300, and the connecting member 300 rotates relative to the hinge base 100 through the rotating member 200, realizes the rotation of the connecting member 300 driving the display panel 20, and realizes the unfolding and closing of the folding electronic device.

[0060] During the folding and unfolding of the electronic device, the damping structure 400 generates a resistance in the opposite direction of the movement through the interaction with the rotating piece 200. When the user operates the device to perform the folding or unfolding action, the resistance can be clearly felt, thereby obtaining a more realistic and comfortable touch feedback and realizing the damping hand feeling. Meanwhile, by reasonably adjusting the characteristics and parameters of the damping structure 400, the device can be stably hovered at different angles, facilitating the user to use.

[0061] The problem of uneven damping force caused by the direct action of the traditional spring on the concave-convex wheel 700 is avoided, so that the resistance felt by the user during the operation is more linear and smooth, and the abrupt jamming feeling does not occur.

[0062] The axial elastic force of the spring directly acts on the concave-convex wheel 700, which is easy to cause the surface of the concave-convex wheel 700 to be worn under long-term action. In the technical solution, the damping structure 400 applies resistance to the rotating piece 200, which bears part of the force originally applied by the spring to the concave-convex wheel 700 and disperses the stress acting on the concave-convex wheel 700. In this way, the pressure and friction force borne by the concave-convex wheel 700 are greatly reduced, and the speed and degree of wear are reduced. In actual use, this means that after a long time of frequent folding and unfolding operation, the concave-convex wheel 700 can still maintain a good working state and will not affect the normal performance of the device due to excessive wear. By reducing the wear and failure risk of the concave-convex wheel 700, the rotating shaft assembly 10 can withstand longer use tests. The overall service life of the device is prolonged.

[0063] Optionally, the rotating piece 200 comprises a sliding part 210 extending in a second direction, and the first direction is perpendicular to the second direction. The connecting piece 300 is provided with a sliding groove 301, and the sliding part 210 can slide relative to the sliding groove 301 in the second direction when the connecting piece 300 rotates relative to the hinge base 100 through the rotating piece 200.

[0064] When the included angle between the connecting piece 300 and the hinge base 100 changes, the cooperation between the sliding part 210 and the sliding groove 301 can guide the movement of the rotating piece 200. Due to the limitation of the sliding groove 301, the rotating piece 200 can only move along the predetermined track, avoiding deviation and shaking caused by uneven stress or other factors, so that the rotating shaft assembly 10 is more stable and reliable during operation, and can ensure that the folding and unfolding of the electronic device are accurately and smoothly performed.

[0065] By setting the sliding part 210 and the sliding groove 301, the stress borne by the rotating piece 200 is dispersed to the entire sliding structure, reducing the local stress concentration. The structural stability of the rotating piece 200 and the entire rotating shaft assembly 10 is improved, and the service life is prolonged.

[0066] Optionally, the first direction is the axial direction of the rotation axis of the rotating member 200, and the second direction is the length direction of the rotating member 200.

[0067] Optionally, the number of the rotating members 200 is set to at least two, and the connecting member 300 is correspondingly arranged with the rotating member 200. When one rotating member 200 is arranged on each of the opposite sides of the hinge base 100, the rotating member 200 drives the corresponding display panel 20 to flip through the corresponding connecting member 300, so that the flipping of at least two display panels 20 can be realized. When at least two rotating members 200 are arranged on the same side of the hinge base 100, each rotating member 200 can be connected with a different display panel 20 through the corresponding connecting member 300, so that the flipping of multiple display panels 20 can be realized. All the rotating members 200 on the same side of the hinge base 100 can also be connected with the same display panel 20, so that more connecting points for fixing the display panel 20 can be provided, and the stress can be more dispersed and uniform.

[0068] Optionally, when the angle between the connecting member 300 and the hinge base 100 increases, the sliding part 210 is inserted into the sliding groove 301 along the second direction. When the angle between the connecting member 300 and the hinge base 100 decreases, the sliding part 210 is moved out of the sliding groove 301 along the second direction.

[0069] When the angle between the connecting member 300 and the hinge base 100 changes, the cooperation between the sliding part 210 and the sliding groove 301 is like a kind of track constraint mechanism. During the increase of the angle, the sliding part 210 is gradually inserted into the sliding groove 301, which provides a clear movement path and limitation for the sliding part 210, and prevents unnecessary shaking, deviation or tilting of the rotating member 200 during movement.

[0070] Referring to Figure 6 As shown in the figure, the groove thickness of part of the sliding groove 301 is less than the thickness of the connecting member 300. In the thickness direction of the connecting member 300, the groove thickness of the sliding groove 301 is less than the thickness of the connecting member 300, which is the limiting effect of the sliding part 210 during the movement in the sliding groove 301, and further improves the stability of the sliding part 210 during the movement in the sliding groove 301.

[0071] Optionally, the sliding part 210 is provided with a second abutting surface 211, the second abutting surface 211 is arranged obliquely relative to the second direction, and the second abutting surface 211 abuts against the damping structure 400.

[0072] Optionally, when the angle between the connecting member 300 and the hinge base 100 increases, i.e. during the unfolding process, the sliding part 210 drives the damping structure 400 to compress through the second abutting surface 211, and the damping force applied by the damping structure 400 to the rotating member 200 increases.

[0073] Optionally, the damping structure 400 is provided with a first abutting surface 401, which is arranged obliquely relative to the second direction, and the first abutting surface 401 abuts against the sliding part 210.

[0074] Optionally, when the angle between the connecting piece 300 and the hinge base 100 increases, i.e., during the unfolding process, the damping structure 400 is compressed by the first abutting surface 401, and the damping force exerted by the damping structure 400 on the rotating piece 200 increases.

[0075] By arranging the second abutting surface 211 and / or the first abutting surface 401 obliquely relative to the second direction, the damping structure 400 can be compressed during the increase of the angle between the connecting piece 300 and the hinge base 100. This compression mode can be flexibly adjusted as needed, thereby changing the damping force exerted by the damping structure 400 on the rotating piece 200. This allows the damping effect during the unfolding and closing of the folding electronic device to be accurately adjusted according to different application scenarios and user needs. Optionally, in some scenarios that require more stable and slow operation, the damping can be increased, so that the user feels more obvious resistance when opening and closing the screen, thereby improving the accuracy and stability of the operation; while in other cases that require rapid opening and closing, the damping can be appropriately reduced to make the operation more smooth.

[0076] Optionally, the obliquely arranged second abutting surface 211 and / or first abutting surface 401 can quickly interact with the damping structure 400 when the angle between the connecting piece 300 and the hinge base 100 changes, so that the damping structure 400 reacts in time and produces a corresponding change in damping force. This improves the response speed of the damping structure 400 to the movement of the rotating piece 200, making the damping effect more immediate and accurate. Optionally, this means that when the user starts to open and close the screen, the damping structure 400 can quickly provide appropriate resistance, enhancing the user's control of the device and making the user feel that the device responds more sensitively and accurately. Optionally, the oblique design makes the force not directly vertically acting during transmission, but decomposing along the oblique direction of the abutting surface. This can avoid excessive local stress and distribute the force more evenly to the damping structure 400 and the rotating piece 200. This reduces the risk of component damage caused by local stress concentration, such as deformation and wear of the damping structure 400 and excessive pressure on the rotating piece 200. At the same time, uniform force distribution also helps to improve the structural stability and reliability of the entire rotating shaft assembly 10, prolong the service life of the device, and ensure the consistency of the damping effect during long-term use.

[0077] Continuing to refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the damping structure 400 includes an elastic member 410 and a pushing member 420.

[0078] The first end of the elastic member 410 is fixed to the rotating member 200, and the second end of the elastic member 410 is retractable in the first direction. The pushing member 420 is connected to the second end of the elastic member 410, and the pushing member 420 abuts against the sliding part 210. The sliding part 210 is provided with a second abutting surface 211, and the pushing member 420 is provided with a first abutting surface 401 on the side facing the sliding part 210. The second abutting surface 211 and the first abutting surface 401 abut against each other.

[0079] In some implementations, the elastic member 410 can be at least one spring member 411. In order to improve the elastic force of the elastic member 410, the spring member 411 can be provided in at least two. The number of spring members 411 can be flexibly controlled, and the size of the resistance applied by the damping structure 400 to the rotating member 200 can also be adjusted as needed.

[0080] Optionally, the pushing member 420 can be a block-shaped pushing member 420 with high wear resistance. The specific material of the pushing member 420 is not limited in the present application.

[0081] When the rotating member 200 is in motion, the sliding part 210 abuts against the pushing member 420, and the pushing member 420 applies the force transmitted by the rotating member 200 to the elastic member 410. Since the second end of the elastic member 410 is retractable in the first direction, it can deform when subjected to force, thereby absorbing and buffering part of the energy. This buffering and energy absorption effect can reduce the damage to the device caused by external force impact or sudden force change during opening and closing. Optionally, when the user quickly closes the folding electronic device, the elastic member 410 in the damping structure 400 can relieve the impact force by deforming, avoiding excessive stress on the hinge base 100, the connecting member 300 and other components, prolonging the service life of the device, and providing a softer operation feeling for the user. The elastic member 410 is fixedly connected to the rotating member 200, so that the damping structure 400 can always be closely linked with the rotating member 200. During the movement of the rotating member 200, the elastic member 410 continuously adjusts its deformation degree according to the position and movement state of the rotating member 200, thereby applying a continuous and relatively stable damping force to the rotating member 200 through the pushing member 420. It ensures that the size and direction of the damping force can be well controlled throughout the opening and closing angle range, and sudden changes or instability of the damping force will not occur. This helps users to feel consistent resistance when operating the folding electronic device, improves the precision and comfort of operation, and provides a good user experience whether in small-angle fine adjustment or in large-angle opening and closing.

[0082] In addition, by setting the elastic member 410, the pushing member 420 always gives the sliding part 210 a force of being pressed in the sliding groove 301, at this time, the elastic member 410 can realize the relative fixation of the rotating part 200 and the connecting part 300 by exerting elastic force, and then the free hovering effect of the display panel 20 can be realized.

[0085] Optionally, the rotating part 200 comprises a sliding part 210, the sliding part 210 extends along a second direction, and the first direction is perpendicular to the second direction.

[0102] Optionally, the rotating member 200 includes a sliding part 210 extending in a second direction, and the first direction is perpendicular to the second direction.

[0103] Optionally, the connecting piece 300 is provided with a sliding groove 301, and the sliding part 210 can slide relative to the sliding groove 301 in the second direction when the connecting piece 300 rotates relative to the hinge base 100 through the rotating piece 200.

[0104] Optionally, the sliding part 210 is inserted into the sliding groove 301 in the second direction when the angle between the connecting piece 300 and the hinge base 100 increases.

[0105] Optionally, the sliding part 210 is moved out of the sliding groove 301 in the second direction when the angle between the connecting piece 300 and the hinge base 100 decreases.

[0106] Optionally, the sliding part 210 is provided with a second abutting surface 211, the second abutting surface 211 is arranged obliquely relative to the second direction, and the second abutting surface 211 abuts against the damping structure 400.

[0107] Optionally, the damping structure 400 is compressed through the second abutting surface 211 when the angle between the connecting piece 300 and the hinge base 100 increases, and the damping structure 400 applies a greater resistance to the rotating piece 200.

[0108] Optionally, the damping structure 400 is provided with a first abutting surface 401, the first abutting surface 401 is arranged obliquely relative to the second direction, and the first abutting surface 401 abuts against the sliding part 210.

[0109] Optionally, the damping structure 400 is compressed through the first abutting surface 401 when the angle between the connecting piece 300 and the hinge base 100 increases, and the damping structure 400 applies a greater resistance to the rotating piece 200.

[0110] Optionally, the damping structure 400 comprises an elastic piece 410 and a pushing piece 420.

[0111] Optionally, a first end of the elastic piece 410 is fixed to the rotating piece 200, and a second end of the elastic piece 410 can be stretched and contracted in the first direction; the pushing piece 420 is connected to the second end of the elastic piece 410, and the pushing piece 420 abuts against the sliding part 210.

[0112] Optionally, the connecting piece 300 is provided with a limiting piece 600, and the damping structure 400 is provided with an abutting part 430.

[0113] Optionally, the limiting piece 600 is arranged on a side of the abutting part 430 away from the rotating piece 200, and the limiting piece 600 is used at least for abutting against the abutting part 430.

[0114] By setting the limiting piece 600 on the connecting piece 300 and the corresponding abutting portion 430 in the damping structure 400, when the angle between the connecting piece 300 and the hinge base 100 changes, the limiting piece 600 can abut against the abutting portion 430. This abutting action can effectively limit and constrain the position of the rotating piece 200. Under different opening and closing angles, the cooperation of the limiting piece 600 and the abutting portion 430 can prevent the rotating piece 200 from excessive swinging or deviation, thereby enhancing the structural stability of the entire rotating shaft assembly 10. Since the positional relationship between the limiting piece 600 and the abutting portion 430 is designed, when they abut against each other, they can provide a clear trigger point and action position for the damping structure 400. This makes the damping structure 400 work accurately according to the preset position and condition to apply resistance. Precise control of the damping force during the opening and closing process of the folding electronic device can be achieved. Alternatively, when the user opens or folds the screen to a certain angle, the interaction between the limiting piece 600 and the abutting portion 430 can make the damping structure 400 generate appropriate resistance, so that the user can clearly feel the change of damping, thereby obtaining better operation feedback. This precise damping control helps to improve the user's operation experience and makes the operation process smoother and more natural.

[0115] Alternatively, when the angle between the connecting piece 300 and the hinge base 100 changes, for example, when the angle changes slightly, the limiting piece 600 can not abut against the abutting portion 430, which means that the limiting piece 600 only limits the maximum displacement of the abutting portion 430 to prevent the abutting portion 430 from being unable to reset when the displacement is too large.

[0116] Alternatively, the connecting piece 300 is provided with a containing groove 302, and the containing groove 302 is in communication with the sliding groove 301.

[0117] Alternatively, the first part of the damping structure 400 is arranged in the containing groove 302, the second part of the damping structure 400 protrudes out of the containing groove 302, and the second part of the damping structure 400 abuts against the rotating piece 200.

[0118] By dividing the damping structure 400 into two parts and arranging them inside and outside the accommodating groove 302 respectively, the damping structure 400 can be more flexibly arranged and adjusted according to different working requirements. The first part is arranged inside the accommodating groove 302 and can be better protected, while providing a stable support environment for the damping structure 400. The second part extends out of the accommodating groove 302 and abuts against the rotating member 200, which can directly play a damping role in the rotating process. This arrangement makes the space utilization of the damping structure 400 in the rotating shaft assembly 10 more reasonable, and can better adapt to different device structures and space limitations. Optionally, in the case of a relatively compact internal space of the folding electronic device, the sizes and shapes of the accommodating groove 302 and the parts of the damping structure 400 can be adjusted according to actual conditions to ensure that the damping structure 400 can work effectively without interfering with other components, thereby improving the overall adaptability and compatibility of the rotating shaft assembly 10.

[0119] Optionally, the communication design of the accommodating groove 302 and the sliding groove 301 facilitates the assembly of the damping structure 400, and also facilitates the inspection, maintenance or replacement of each part of the damping structure 400, thereby reducing the difficulty of assembly and maintenance and improving production efficiency and device maintainability.

[0120] Fourth embodiment

[0121] The present application provides a rotating shaft assembly 10, comprising:

[0122] The hinge base 100 extends along a first direction;

[0123] The rotating member 200 is arranged on the hinge base 100 and can rotate around the first direction;

[0124] The connecting member 300 can be used to fix the display panel 20, and the connecting member 300 can rotate relative to the hinge base 100 through the rotating member 200; the connecting member 300 is provided with a damping structure 400, and the damping structure 400 can at least apply a resistance to the rotating member 200.

[0125] Optionally, the rotating member 200 is provided with a concave-convex wheel 700, and the concave-convex wheel 700 has at least two first matching parts 710, and the plurality of first matching parts 710 are sequentially and spaced apart around the first direction.

[0126] Optionally, the hinge base 100 is provided with a second matching part (not shown in the figure), and the second matching part can cooperate with the first matching part 710 to fix the rotating member 200 and the hinge base 100.

[0127] Optionally, the first matching part 710 and the second matching part can be a convex and groove matching. In the prior art, a spring is arranged on the hinge base 100, and the axial elastic force of the spring directly acts on the convex and groove 700. In the case of long-time work of the rotating part 200, the surface of the convex and groove 700 is prone to wear. By arranging at least two first matching parts 710 on the convex and groove 700 of the rotating part 200, and arranging corresponding second matching parts on the hinge base 100, when the angle between the rotating part 200 and the hinge base 100 is adjusted to the appropriate position, the matching parts can be matched with each other, thereby realizing the firm fixation between the rotating part 200 and the hinge base 100. This fixing mode is based on the mutual matching of the convex and groove structure, and has high connection stability. Under different opening and closing angles, stable support can be provided for the folding electronic device. Since the plurality of first matching parts 710 on the convex and groove 700 are arranged in the first direction, the rotating part 200 can be stopped at different angle positions in a more accurate manner when rotating relative to the hinge base 100. Each first matching part 710 corresponds to a specific opening and closing angle. By controlling the rotation of the convex and groove 700, the rotating part 200 can be accurately stopped at the required angle to realize the hovering at a specific angle.
