Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of terminal equipment, in particular to a damping structure and a foldable device. BACKGROUND

[0002] Thanks to the portability and powerful processing capability of foldable devices such as notebook computers, foldable-screen mobile phones, etc., foldable devices have become important daily office productivity tools.

[0003] The foldable device includes a first folding body and a second folding body. The first folding body and the second folding body are relatively rotatable to switch between an open state and a closed state. When the foldable device is in the open state, the second folding body can be supported on a support surface, so as to facilitate the user to exert a clicking or tapping operation on the first folding body. For example, the first folding body can be a display of a notebook computer, and the user exerts a touch operation on the display. However, when the user exerts a clicking or tapping operation on the first folding body, there is a problem of shaking of the first folding body, and the user experience is poor. SUMMARY

[0004] Therefore, the present application provides a damping structure and a foldable device. The foldable device is provided with the damping structure, which can quickly absorb kinetic energy generated when the first folding body shakes under external force, at least to some extent, weaken the shaking of the first folding body, and improve the user experience.

[0005] To achieve the above object, the present application adopts the following technical solutions:

[0006] In a first aspect, the present application provides a foldable device, which includes a first folding body, a second folding body, and a hinge mechanism. The hinge mechanism includes a first rotating member and a second rotating member. The first rotating member is fixed relative to the first folding body. The second rotating member is rotatably connected to the first rotating member. The second rotating member is fixedly connected to the second folding body through a damping structure.

[0007] According to the foldable device of the present application, the damping structure has damping capacity and damping characteristics. When the user exerts a clicking or tapping operation on the first folding body, the force acting on the first folding body is transmitted to the first rotating member. Since the second rotating member is rotatably connected to the first rotating member, the force acting on the first rotating member is transmitted to the second rotating member. Since the second rotating member is fixedly connected to the second folding body through the damping structure, the force acting on the second rotating member is transmitted to the damping structure. The damping structure can quickly absorb the kinetic energy transmitted by the second rotating member by using its damping capacity and damping characteristics, so as to quickly stabilize the first folding body, effectively solving the problem of shaking of the first folding body and long shaking time of the first folding body.

[0008] In some possible implementation manners of the first aspect of the present application, the damping structure comprises a first rigid member and a flexible member, the first rigid member is fixedly connected with the second rotating member, and the flexible member is fixed between the first rigid member and the second folding body. In this way, on the one hand, the first rigid member is arranged in the damping structure, which facilitates the connection between the damping structure and the second rotating member and facilitates the support of the second rotating member by the first rigid member; on the other hand, the flexible member is arranged in the damping structure, and the force transmitted to the second rotating member is transmitted to the flexible member through the first rigid member, the kinetic energy transmitted by the second rotating member can be quickly absorbed by the flexible member, so that the first folding body is quickly stabilized, and the problems of the first folding body shaking and the shaking time of the first folding body being long are effectively solved. Moreover, the damping structure has a simple structure.

[0009] In some possible implementation manners of the first aspect of the present application, the second rotating member has a first fixing hole. The first rigid member comprises a first cylinder body, and an inner circumferential wall of the first cylinder body has a first internal thread.

[0010] In some possible implementation manners of the first aspect of the present application, the flexible member comprises a flexible cylinder body, the flexible cylinder body surrounds the outer periphery of the first cylinder body and is connected with the first cylinder body.

[0011] In some possible implementation manners of the first aspect of the present application, one end of the first cylinder body away from the first fixing hole is located in the flexible cylinder body. In this way, the one end of the first cylinder body located in the flexible cylinder body may or at least to some extent abut against the inner wall of the flexible cylinder body, in this state, the flexible cylinder body is deformed in the axial direction to quickly absorb the kinetic energy transmitted by the second rotating member to the flexible cylinder body, so as to realize damping in the axial direction. In addition, the flexible cylinder body can serve as an external flexible protective barrier of the first cylinder body, which can prevent the first cylinder body from hard contact with the components inside the second folding body, avoid the force transmitted to the first rigid member from being transmitted to other structures of the second folding body, and improve the damping effect.

[0012] In some possible implementation manners of the first aspect of the present application, the fastener comprises a head and a screw rod, the head abuts against a side surface of the second rotating member facing away from the first rigid member, the screw rod is connected with the head, an outer circumferential surface of the screw rod has the first external thread, and one end of the screw rod is connected with the head. In this way, the structure is simple and convenient for assembly.

[0013] In some possible implementation manners of the first aspect of the present application, the other end of the screw rod is located in the flexible cylinder. In this way, the flexible cylinder can prevent the other end of the screw rod located in the flexible cylinder from hard contact with other structures in the interior of the second folding body, so that the force transmitted to the first rigid member is prevented from being transmitted to other structures of the second folding body, and the damping effect is improved.

[0016] In some possible implementation manners of the first aspect of the present application, the second folding body comprises a second housing, the second housing has a mounting hole, the rotating shaft mechanism is arranged in the mounting hole, at least a part of the second rotating member is located in the second housing, a protruding portion is arranged on an inner surface of the second housing, and a part of an end face of a protruding end of the protruding portion is recessed to form the fixing groove. In this way, the protruding portion is arranged, so that the fixing groove can be arranged on the protruding portion, thereby facilitating the fixation of the damping structure, and the structural strength of the second housing at the protruding portion is improved, and the stability of the support to the second rotating member can be improved.

[0017] In some possible implementation manners of the first aspect of the present application, the second rigid member comprises a second cylinder, and the second cylinder has a second external thread on an outer circumferential surface thereof. The first rigid member comprises a first cylinder and a rigid flange, the second cylinder surrounds the outer periphery of the first cylinder, the rigid flange is arranged at one end of the first cylinder adjacent to the second rotating member in the axial direction, and the rigid flange is arranged at one side of the first cylinder adjacent to the second rotating member in the axial direction. A head matching groove is arranged on a surface of the rigid flange away from the first cylinder, and the head matching groove is adapted to be matched with a head. In this way, the axial directions of the first cylinder and the second cylinder are the same, for example, the central axes of the first cylinder and the second cylinder are coaxial. In addition, the second external thread is arranged on the outer circumferential surface of the second cylinder. Therefore, during the assembly of the foldable device by the line worker, the line worker can match the head (for example, a screwdriver) with the head matching groove to rotate the damping structure, so that the second external thread is matched with the third internal thread, the damping structure is locked into the fixing groove by means of the head, the operation is convenient, and the assembly effect can be improved.

[0018] In some possible implementation manners of the first aspect of the present application, the first rigid member, the second rigid member and the flexible member are an integral piece. In this way, on the one hand, the first rigid member, the second rigid member and the flexible member can be disassembled and assembled as a whole, facilitating maintenance and replacement; on the other hand, the processing technology of the first rigid member, the second rigid member and the flexible member is simplified, the processing efficiency of the first rigid member, the second rigid member and the flexible member is improved, and the processing cost of the first rigid member, the second rigid member and the flexible member is reduced.

In this way, the contact area between the first rigid member and the second rotating member is increased, and the reliability of the connection therebetween is improved.

[0020] In some possible implementation manners of the first aspect of the present application, the flexible member includes a flexible cylinder body and a flexible flange, and the flexible cylinder body surrounds the first cylinder body and is connected with the first cylinder body. In this way, the flexible cylinder body is arranged to absorb the kinetic energy transmitted by the second rotating member to the first cylinder body, thereby playing a role of shock absorption.

[0021] In some possible implementation manners of the first aspect of the present application, the flexible flange is arranged at one end of the flexible cylinder body close to the rigid flange, the flexible flange is located at a side of the rigid flange close to the first cylinder body, and the flexible flange is arranged in a stacked manner with the rigid flange. In this way, compared with shock absorption only through the flexible cylinder body, the flexible flange can be used to separate the second shell from the rigid flange, so as to avoid contact between the rigid flange and the second shell, facilitate the flexible flange to absorb the kinetic energy transmitted by the second rotating member to the rigid flange, improve the shock absorption effect, and the flexible flange increases the structural strength of the flexible member.

[0022] In some embodiments of the present application, the second rigid member includes a second cylinder body, the second cylinder body surrounds the flexible cylinder body and is connected with the flexible cylinder body. The surface of the flexible flange away from the rigid flange is fixed to the end face of one end of the second cylinder body in the axial direction. In this way, the flexible flange can be used to separate the second shell from the rigid flange, so as to avoid contact between the rigid flange and the second shell, facilitate the flexible flange to absorb the kinetic energy transmitted by the second rotating member to the rigid flange, improve the shock absorption effect, and the flexible flange increases the structural strength of the flexible member.

[0023] In some possible implementation manners of the first aspect of the present application, the second rigid member further comprises a limiting protrusion, the limiting protrusion is arranged on an end face of an axial end of the second barrel, the rigid flange is provided with a first avoiding gap, the flexible flange is provided with a second avoiding gap, and the limiting protrusion is fitted into the first avoiding gap and the second avoiding gap. In this way, the limiting protrusion can limit the first rigid member and the flexible member in the circumferential direction of the first barrel, prevent the first rigid member and the flexible member from being deviated in the circumferential direction relative to the second rigid member, and further avoid tearing of the flexible barrel due to the deviation, for example, when the rotation damping structure enables the second external thread to cooperate with the third internal thread, the first rigid member and the flexible member are prevented from being deviated in the circumferential direction relative to the second rigid member, and the damping effect of the damping structure is ensured.

[0024] In some possible implementation manners of the first aspect of the present application, the limiting protrusion, the first avoiding gap and the second avoiding gap are all in plurality, and one limiting protrusion, one first avoiding gap and one second avoiding gap correspond to each other. In this way, the limiting effect of the limiting protrusion on the first rigid member and the flexible member in the circumferential direction of the first barrel is further improved.

[0025] In some possible implementation manners of the first aspect of the present application, the first rigid member is a metal member. In this way, the connection strength of the first rigid member and the second rotating member is improved.

[0026] In some possible implementation manners of the first aspect of the present application, the flexible member is a rubber member or a silica gel member. In this way, the rubber member or the silica gel member has the characteristics of damping, buffering and large elastic deformation, can quickly absorb kinetic energy generated when the first folding body shakes, and ensures the stability of the first folding body when the first folding body is touched. Moreover, the rubber member or the silica gel member has low cost.

[0027] In some possible implementation manners of the first aspect of the present application, the damping coefficient of the flexible member is in the range of 0.8 to 1. In this way, on the one hand, the problem that the flexible member cannot quickly absorb kinetic energy transmitted by the second rotating member and cannot ensure the rapid stability of the first folding body due to the damping coefficient being set too small can be prevented; on the other hand, the problem that the flexible member is too soft and cannot be reliably connected with the first rigid member and the second housing due to the damping coefficient being set too large can be prevented. That is, by limiting the damping coefficient of the flexible member to 0.8 to 1, the flexible member can play the best damping role in the connection relationship among the first rotating member, the second rotating member and the damping structure.

[0060] The present application provides a foldable device, including but not limited to notebook computer, folding screen mobile phone, laptop computer, personal digital assistant (PDA), personal computer, vehicle-mounted device and accessories of these devices (such as mobile phone support, tablet computer support, selfie stick, tablet computer protective sleeve, etc.).

[0061] Please refer to Figure 1 , Figure 1 The structural schematic diagram of the foldable device 100 provided for some embodiments of the present application is shown. In the present embodiment, the foldable device 100 is exemplarily illustrated as a notebook computer. The foldable device 100 includes a display 1, a keyboard host 2 and a rotating shaft mechanism (not shown in the figure). Figure 1

[0062] It should be noted that Figure 1 Only some components included in the foldable device 100 are schematically shown, and the actual shape, actual size, actual position and actual structure of these components are not limited by Figure 1 In the foldable device 100, the display 1 is taken as the first folding body and the keyboard host 2 is taken as the second folding body for example. In other embodiments, the display 1 can be the second folding body and the keyboard host 2 can be the first folding body.

[0063] ​The display 1 is used to display images, videos, etc. The display 1 can be an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode display, a micro organic light-emitting diode display, a micro organic light-emitting diode display, a quantum dot light emitting diode (QLED) display, or a liquid crystal display (LCD).

[0064] Please continue to refer to Figure 1 The display 1 includes a display screen 11 and a first housing 12. The display screen 11 can be a flexible display screen 11 or a rigid display screen 11. The first housing 12 is used to protect the display screen 11. The first housing 12 can wrap around the edges of the display screen 11 and the back of the display screen 11.

[0065] In some embodiments of the present application, in order to improve the structural strength of the foldable device 100, the first housing 12 is a metal piece. For example, the first housing 12 is an aluminum alloy piece, a magnesium alloy piece, a stainless steel piece, etc. In other embodiments of the present application, in order to reduce the weight of the foldable device 100, the first housing 12 can also be a plastic piece.

[0066] For example, the display screen 11 can be integrated with a touchpad. In this way, the touch function of the display screen 11 can be realized, that is, the display 1 is a touch display. Of course, in other examples, the display screen 11 can not be integrated with a touchpad, and in this case, the display screen 11 can not have a touch function.

[0067] The keyboard host 2 is used to input instructions and data, and controls the display 1 to display images, videos according to the input instructions and data. The keyboard host 2 and the display 1 can be relatively rotated. Through the rotatable connection of the keyboard host 2 and the display 1, the foldable device 100 can be switched between the open state and the closed state.

[0068] Please continue to refer to Figure 1When the foldable device 100 is in the open state, the keyboard host 2 and the display 1 form an angle greater than 0° and less than 360°. In this state, the user can control the display of the display 1 by operating the keyboard host 2, and the user can also view the images or videos displayed on the display 1.

[0069] Please see Figure 2 , Figure 2 According to Figure 1 The diagram shows the structure of the foldable device 100 in its closed state. When the foldable device 100 is in the closed state, the display 1 covers the keyboard host 2, and the display surface of the display screen 11 is opposite to the keyboard surface of the keyboard host 2. In this state, the display surface of the display 1 and the keyboard surface of the keyboard host 2 can be protected from scratches and dust, and the foldable device 100 can also be easily stored and carried.

[0070] For ease of description in the following embodiments, an XYZ coordinate system is established for the keyboard host 2. Specifically, the extension direction of the rotation axis between the keyboard host 2 and the display 1 is defined as the X-axis direction, the thickness direction of the keyboard host 2 is defined as the Z-axis direction, and the direction perpendicular to both the X-axis and Z-axis directions is defined as the Y-axis direction. It is understood that the coordinate system settings of the keyboard host 2 can be flexibly configured according to actual needs, and are not specifically limited here. Furthermore, in actual user applications, with the foldable device 100 in its open state and the user facing the display surface of the display 1, the X-axis direction represents the user's left-right direction, the Y-axis direction represents the front-back direction, and along the Y-axis direction, the direction closer to the user is the forward direction.

[0071] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a keyboard host 2 provided in some embodiments of this application. The keyboard host 2 includes a second housing 21 and a keyboard 22.

[0072] The second housing 21 protects the internal structure of the keyboard host 2. Furthermore, when the user uses the foldable device 100, the keyboard host 2 comes into contact with the user or other external structures through the second housing 21. This inevitably leads to scratches and corrosion on the outer surface of the second housing 21. To avoid this technical problem, the second housing 21 can have certain wear-resistant, corrosion-resistant, and scratch-resistant properties, or its outer surface can be coated with a functional material for wear resistance, corrosion resistance, and scratch resistance.

[0073] In some embodiments of this application, the second housing 21 is made of metal to improve the structural strength of the foldable device 100. Exemplarily, the second housing 21 is made of aluminum alloy, magnesium alloy, stainless steel, etc. In other embodiments of this application, the second housing 21 may also be made of plastic to reduce the weight of the foldable device 100.

[0074] In some embodiments, the second housing 21 can be formed as one structure. That is, the second housing 21 can be formed as an integral structure, and the integral structure of the second housing 21 has higher structural strength and higher processing efficiency.

[0075] In other embodiments, the second housing 21 can also be formed by assembling multiple parts. Please continue to refer to Figure 3 The second housing 21 includes a C housing 212 and a D housing 213. The C housing 212 and the D housing 213 are closed in the Z-axis direction to enclose an internal space of the second housing 21. The second housing 21 is formed by assembling the C housing 212 and the D housing 213, which facilitates the processing of the C housing 212 and the D housing 213, simplifies the mold structure of the C housing 212 and the D housing 213, reduces the difficulty of forming the C housing 212 and the D housing 213, and further reduces the difficulty of processing and manufacturing the second housing 21.

[0076] Specifically, the C housing 212 can be fixedly connected to the D housing 213 by a snap-fit manner. The C housing 212 can also be connected to the D housing 213 by a screw connection. The C housing 212 can also be connected to the D housing 213 by a magnetic attraction. The C housing 212 can also be connected to the D housing 213 by welding. Alternatively, in other embodiments, the C housing 212 can also be fixedly connected to the D housing 213 by glue or adhesive tape. The present application does not make specific limitations in this regard.

[0077] Specifically, please continue to refer to Figure 3 The C housing 212 includes a bearing plate 2121 and a first side frame 2122.

[0078] The bearing plate 2121 is in the form of a flat plate. The bearing plate 2121 is used to bear functional devices such as the keyboard 22. In addition, when a user uses the foldable device 100, the bearing plate 2121 can also be used to bear the user's hand to facilitate the user to strike the keyboard 22.

[0079] The material of the bearing plate 2121 includes but is not limited to hard plastic, metal, and a combination of plastic and metal. In this way, it is beneficial to improve the structural strength of the bearing plate 2121, thereby improving the bearing effect of the bearing plate 2121. In order to realize the lightweight of the foldable device 100, the material of the bearing plate 2121 can be selected as hard plastic.

[0080] The first side frame 2122 is arranged around the edge of the bearing plate 2121. When the C housing 212 and the D housing 213 are closed, the first side frame 2122 is connected between the bearing plate 2121 and the D housing 213. The material of the first side frame 2122 includes but is not limited to hard plastic, metal, and a combination of plastic and metal. In this way, it is beneficial to improve the structural strength of the first side frame 2122. In some embodiments, please continue to refer to Figure 3The C-shell 212 can be a one-piece molded part, meaning that the supporting plate 2121 and the first side frame 2122 are a single structural unit. This simplifies the processing technology of the C-shell 212, improves its processing efficiency, reduces its production cost, and also enhances its structural strength.

[0081] D-shell 213 includes a support plate 2131. The support plate 2131 is flat. The support plate 2131 and the bearing plate 2121 are arranged opposite to each other in the Z-axis direction. "The support plate 2131 and the bearing plate 2121 are arranged opposite to each other" means that they can be parallel, or they are allowed to have a certain angle, for example, the angle between them is between 0 and 45°. Exemplarily, D-shell 213 is defined by the support plate 2131. Also exemplaryly, D-shell 213 includes the support plate 2131 and a second side frame (…). Figure 3 (Not shown). The second side frame is arranged around the edge of the support plate 2131. When the C shell 212 and the D shell 213 are engaged, the second side frame connects the support plate 2131 and the C shell 212. The material of the support plate 2131 includes, but is not limited to, rigid plastic, metal, and a combination of plastic and metal. This helps to improve the structural strength of the support plate 2131. In order to achieve the lightweight of the foldable device 100, the material of the support plate 2131 can be rigid plastic.

[0082] Specifically, the hinge mechanism 3 connects the keyboard host 2 and the monitor 1, allowing them to rotate. Specifically, the keyboard host 2 and the monitor 1 can rotate relative to each other via the hinge mechanism 3, enabling the foldable device 100 to switch between an open and folded state, thus allowing the foldable device 100 to open or fold. In some examples, the hinge mechanism 3 can be a damping hinge mechanism, which provides damping force to the relative rotation of the keyboard host 2 and the monitor 1, allowing the foldable device 100 to maintain a target opening angle position between 0° and 360° for user convenience. The target opening angle can be a fixed value between 0° and 360°, or any value between 0° and 360°; this application does not specifically limit this. In other examples, the hinge mechanism 3 may not be a damping hinge mechanism 3.

[0083] For easier fixing of the rotating shaft mechanism 3, please refer to [link / reference needed]. Figure 3 The second housing 21 has mounting holes 215. Specifically, the first side frame 2122 has mounting holes 215. The shape of the mounting holes 215 includes, but is not limited to, circular, square, semi-circular, or irregular shapes. The pivot mechanism 3 passes through the mounting holes 215. The portion of the pivot mechanism 3 located inside the second housing 21 is fixedly connected to the second housing 21, and the portion of the pivot mechanism 3 located outside the second housing 21 is fixed to the display 1.

[0084] For example, the mounting holes 215 are provided in two, and the two mounting holes 215 are oppositely arranged. The rotating shaft mechanisms 3 are two. The two rotating shaft mechanisms 3 correspond to the two mounting holes 215 one by one. Of course, the present application is not limited to this. In other embodiments, the rotating shaft mechanisms 3 and the mounting holes 215 can also be one.

[0085] Please refer to Figure 4 and Figure 5 , Figure 4 is a structural schematic diagram of the rotating shaft mechanism 3 in some embodiments of the present application, Figure 5 is an exploded view of the rotating shaft mechanism 3 according to Figure 4 . The rotating shaft mechanism 3 includes a first rotating part 31, a second rotating part 32 and a damping assembly 33.

[0086] The first rotating part 31 is used to be fixedly connected with the display 1. The first rotating part 31 includes a rotating bracket 312 and a rotating shaft 311. The rotating shaft 311 is arranged through the mounting hole 215. The rotating bracket 312 is located outside the second housing 21 and is fixedly connected with the rotating shaft 311. Specifically, the first rotating part 31 can be fixedly connected with the first housing 12 of the display 1 by means of the rotating bracket 312. In order to realize the fixation of the first rotating part 31 and the first housing 12, some embodiments are provided with a third fixing hole 3121 on the rotating bracket 312. The fourth fixing hole (not shown in the figure) is arranged on the first housing 12. The third fixing hole 3121 and the fourth fixing hole are rigidly connected by means of screws, bolts, rivets and the like. Figure 4

[0087] In order to improve the structural strength of the first rotating part 31, the first rotating part 31 is a metal piece. For example, the first rotating part 31 is an aluminum alloy piece, a magnesium alloy piece or a stainless steel piece and the like.

[0088] The second rotating part 32 is rotatably connected with the first rotating part 31. The rotation axis of the second rotating part 32 and the first rotating part 31 is the rotation axis of the display 1 and the keyboard host 2. The rotatable connection between the second rotating part 32 and the first rotating part 31 can realize the relative rotation of the display 1 and the keyboard host 2.

[0089] Specifically, the second rotating part 32 is rotatably connected with the rotating shaft 311. For example, please refer to Figure 5 , the second rotating part 32 is provided with a shaft hole 321, and the rotating shaft 311 is arranged through the shaft hole 321 and rotates in the shaft hole 321. In other embodiments, the shaft hole 321 can also be arranged on the first rotating part 31, and the rotating shaft 311 is arranged on the second rotating part 32.

[0090] Please refer to Figure 6 , Figure 6 is a structural schematic diagram of the rotating shaft mechanism 3 according to​Figure 3 A cross-sectional view of the keyboard host shown in FIG. 1 at the A-A line. The second rotating member 32 is located in the second housing 21. On this basis, the second rotating member 32 can be fixedly connected with the second housing 21. In some embodiments, the second housing 21 is provided with a first connecting hole 214, and the second rotating member 32 is provided with a second connecting hole 322. The first connecting hole 214 and the second connecting hole 322 are rigidly connected by screws, bolts, rivets, etc.

[0091] In order to improve the structural strength of the second rotating member 32, the second rotating member 32 is a metal piece. For example, the second rotating member 32 is an aluminum alloy piece, a magnesium alloy piece, or a stainless steel piece, etc.

[0092] It is worth noting that the foregoing is described by taking the second rotating member 32 located in the second housing 21 and the first rotating member 31 passing through the mounting hole 215 as an example. In other examples, the second rotating member 32 can pass through the mounting hole 215, and at this time, a part of the second rotating member 32 is located in the second housing 21, and another part is located outside the second housing 21, and the first rotating member 31 is located outside the second housing 21. As long as at least a part of the second rotating member 32 is located in the second housing 21, so that the rotating shaft mechanism 3 passes through the mounting hole 215.

[0093] Please continue to refer to Figure 4 and Figure 5 The rotating shaft mechanism 3 can further include a damping assembly 33. The damping assembly 33 is located in the second housing 21 and passes through the rotating shaft 311. The damping assembly 33 is used to provide a damping force for the relative rotation of the first rotating member 31 and the second rotating member 32. In this way, it is convenient for the display 1 to be opened to any angle relative to the keyboard host 2. Of course, in other embodiments, the damping assembly 33 can be defined by the rotating shaft 311 and the shaft hole 321, and when the rotating shaft 311 and the shaft hole 321 are in interference fit, the friction force of the relative rotation of the two can provide a damping force for the relative rotation of the first rotating member 31 and the second rotating member 32. In this way, on the one hand, when the display 1 is rotated relative to the keyboard host 2, a damping feeling can be provided for the user under the action of the damping force, providing the user's use experience; on the other hand, when the user opens the foldable device 100 to a target opening angle, the display 1 and the keyboard host 2 can be maintained at the current target opening angle under the action of the damping force, and the display 1 will not fall back due to gravity, thereby achieving the limiting of the foldable device 100 at the target opening angle, and improving the stability of the rotating shaft mechanism 3 and the electronic device.

[0094] It can be found from the above description that the display 1 and the rotating shaft mechanism 3, and the rotating shaft mechanism 3 and the keyboard host 2 are rigidly connected, and the display 1, the rotating shaft mechanism 3 and the keyboard host 2 are rigid members, and the damping characteristics are poor. Under the action of the damping assembly 33, when the user applies a clicking or tapping action to the display surface of the display screen 11, for example, the display screen 11 is a touch display screen, and the user applies a touch operation to the display screen 11, or for example, the user clicks on the display surface of the non-touch display screen 11 with a finger to prompt important information to others, the force applied to the display 1 is transmitted to the rotating shaft mechanism 3 and the keyboard host 2 in turn, based on the above rigid connection, the force has no place to release, thereby causing the screen to shake for a long time, affecting the product use experience.

[0095] To solve the above technical problems, the application provides a foldable device 100. Please refer to Figure 7 , Figure 7 The keyboard host 2 and the rotating shaft mechanism 3 of some other embodiments in the application are provided with a partial cross-sectional schematic view. The difference between the foldable device 100 and the foldable device 100 in the above embodiment is that the rotating shaft mechanism 3 further comprises a damping structure 34.

[0096] The second rotating part 32 and the keyboard host 2 are fixedly connected through the damping structure 34. Specifically, the second rotating part 32 and the second shell 21 are fixedly connected through the damping structure 34.

[0097] Specifically, since the damping structure 34 has damping capacity and damping characteristics, when the user applies a clicking or tapping action to the display surface of the display screen 11, for example, the display screen 11 is a touch display screen, and the user applies a touch operation to the display screen 11, the force received by the display 1 will be transmitted to the first rotating part 31, since the second rotating part 32 is rotationally connected with the first rotating part 31, the force received by the first rotating part 31 will be transmitted to the second rotating part 32, since the second rotating part 32 is fixedly connected with the keyboard host 2 through the damping structure 34. Therefore, the force transmitted to the second rotating part 32 will be transmitted to the damping structure 34, and the damping structure 34 can quickly absorb the kinetic energy transmitted by the second rotating part 32 by using its damping capacity and damping characteristics, thereby quickly stabilizing the display 1, and effectively solving the problems of display 1 shaking and display 1 shaking for a long time.

[0098] Please continue to refer to Figure 7The inner surface of the second housing 21 is provided with a protrusion 211. For example, the inner surface of the support plate 2131 is provided with the protrusion 211. In other embodiments, the protrusion 211 can also be provided on the bearing plate. The end surface of the protruding end of the protrusion 211 is recessed in part to form a fixing groove 2111. The damping structure 34 is fixed in the fixing groove 2111. In this way, by providing the protrusion 211, the fixing groove 2111 can be conveniently provided on the protrusion 211, thereby facilitating the fixation of the damping structure 34, and being conducive to improving the structural strength of the second housing 21 at the protrusion 211, and can improve the stability of the support of the second rotating member 32.

[0099] The specific structure of the damping structure 34 will be described below.

[0100] Please refer to Figure 7 , Figure 8 and Figure 9 , Figure 8 for the schematic view of the damping structure 34 according to Figure 7 , Figure 9 for the exploded view of the damping structure 34 according to Figure 8 . The damping structure 34 comprises a damping component. The damping component comprises a first rigid member 341 and a flexible member 342.

[0101] The first rigid member 341 is fixedly connected with the second rotating member 32. Specifically, the first rigid member 341 is fixedly connected with the end of the second rotating member 32 away from the shaft hole 321. Since the first rigid member 341 has a certain hardness and is not easy to deform, the connection strength of the first rigid member 341 and the second rotating member 32 can be improved.

[0102] In order to improve the structural strength of the first rigid member 341, the first rigid member 341 is a metal member. For example, the first rigid member 341 is an aluminum alloy member, a magnesium alloy member or a stainless steel member, etc. The metal member has the characteristics of high strength and high hardness. In this way, the connection strength of the first rigid member 341 and the second rotating member 32 can be improved.

[0103] The flexible member 342 mainly plays a damping role in the damping structure 34. The flexible member 342 is fixed between the first rigid member 341 and the keyboard host 2. Specifically, the flexible member 342 is fixed between the first rigid member 341 and the groove wall of the fixing groove 2111.

[0104] In this way, on the one hand, the first rigid piece 341 is arranged in the damping structure 34, facilitating the connection of the damping structure 34 and the second rotating piece 32, and facilitating the support of the first rigid piece 341 to the second rotating piece 32; on the other hand, the flexible piece 342 is arranged in the damping structure 34, and the force transmitted to the second rotating piece 32 will be transmitted to the flexible piece 342 through the first rigid piece 341, and the kinetic energy transmitted by the second rotating piece 32 can be quickly absorbed by the flexible piece 342, so that the display 1 is quickly stabilized, and the problems of display 1 shaking and long shaking time of the display 1 are effectively solved. Moreover, the damping structure 34 has a simple structure.

[0105] In some embodiments of the present application, the flexible piece 342 can be a rubber piece. The rubber piece has the characteristics of damping, buffering, and large elastic deformation, and can quickly absorb the kinetic energy generated when the display 1 shakes, ensuring the stability of the display 1 when touching. Moreover, the rubber piece has low cost. In other embodiments, the flexible piece 342 can also be a silica gel piece.

[0106] In some embodiments of the present application, the damping coefficient of the flexible piece 342 is in the range of 0.8-1. For example, the damping coefficient of the flexible piece 342 can be 0.81, 0.825, 0.83, 0.835, 0.85, 0.865, 0.87, 0.89, 0.905, 0.91, 0.93, 0.94, 0.96, 0.97, 0.98, 0.99, 0.995, or 0.1.

[0107] Generally speaking, the greater the damping coefficient, the more energy dissipation in the vibration system, the smaller the amplitude, and the vibration tends to be stable. The smaller the damping coefficient, the less energy dissipation in the vibration system, the greater the amplitude, and the more intense the vibration. By limiting the damping coefficient of the flexible piece 342 to 0.8-1, on the one hand, it can prevent the problem that the flexible piece 342 cannot quickly absorb the kinetic energy transmitted by the second rotating piece 32 and cannot ensure the quick stability of the display 1 due to the damping coefficient being set too small; on the other hand, it can prevent the problem that the flexible piece 342 is too soft and cannot be reliably connected with the first rigid piece 341 and the second housing 21 due to the damping coefficient being set too large. That is, by limiting the damping coefficient of the flexible piece 342 to 0.8-1, the flexible piece 342 can play the best damping role in the connection relationship among the first rotating piece 31, the second rotating piece 32, and the damping structure 34.

[0108] On this basis, please continue to refer to Figure 7 , Figure 8 and Figure 9In some embodiments of the present application, the second rotating member 32 has a first fixing hole 323. Exemplarily, the first fixing hole 323 has a shape including but not limited to a circle, a polygon, a semicircle, or a special shape.

[0109] The first fixing hole 323 penetrates through the second rotating member 32.

[0110] The first rigid member 341 includes a first cylinder 3411 and a rigid flange 3412. The inner circumferential wall of the first cylinder 3411 has a first internal thread 3411a.

[0111] Please refer to Figure 7 , the damping structure 34 further includes a fastener 344. The outer circumferential surface of the fastener 344 has a first external thread 3442a. The fastener 344 is sequentially arranged in the first fixing hole 323 and the first cylinder 3411. The first external thread 3442a cooperates with the first internal thread 3411a. In this way, the connection mode of the threaded connection is simple, easy to assemble and disassemble, and convenient for maintenance; and the internal thread of the first cylinder 3411 is convenient for processing and manufacturing.

[0112] In other embodiments, in order to improve the connection reliability of the damping structure 34 and the second rotating member 32, the inner circumferential wall of the first fixing hole 323 is formed with a second internal thread 3231, and the first external thread 3442a cooperates with the second internal thread 3231 and the first internal thread 3411a, respectively.

[0113] Please continue to refer to Figure 7 , the fastener 344 includes a head 3441 and a screw rod 3442. The head 3441 abuts against the side surface of the second rotating member 32 facing away from the first rigid member 341. One end of the screw rod 3442 is connected with the head 3441. The outer circumferential surface of the screw rod 3442 has the first external thread 3442a. In this way, the structure is simple and easy to assemble. Of course, the present application is not limited thereto, and in other embodiments, the fastener 344 can also include only the screw rod 3442.

[0114] It is worth noting that the foregoing is an example of the second rotating member 32 and the damping structure 34 being threadedly connected by the fastener 344. In other embodiments, the second rotating member 32 and the first rigid member 341 can also be fixedly connected without the fastener 344, and the first rigid member 341 and the second rotating member 32 can be connected by welding, clamping, or bonding.

[0115] Please refer to Figure 7 , Figure 8 and Figure 9The rigid flange 3412 is arranged at one end of the first cylinder 3411 axially adjacent to the first fixing hole 323. The rigid flange 3412 is in abutment with the end of the second rotating member 32 away from the head 3441. Thus, the contact area between the first rigid member 341 and the second rotating member 32 is increased, and the reliability of the connection between the first rigid member 341 and the second rotating member 32 is improved.

[0116] For example, the first rigid member 341 can be a one-piece member, that is, the first cylinder 3411 and the rigid flange 3412 are connected as one. In this way, on the one hand, the first rigid member 341 can be disassembled and assembled as a whole, which is convenient for maintenance and replacement. On the other hand, the processing technology of the first rigid member 341 is simplified, the processing efficiency of the first rigid member 341 is improved, and the processing cost of the first rigid member 341 is reduced. Of course, it can be understood that in other embodiments, the first cylinder 3411 and the rigid flange 3412 can also be assembled and fixed, for example, the fixing modes of the two include but are not limited to welding, bonding or clamping, etc.

[0117] It should be noted that the foregoing is described by taking the first rigid member 341 as an example, which includes the first cylinder 3411 and the rigid flange 3412. However, the structure of the first rigid member 341 is not limited thereto, and in other embodiments, the first rigid member 341 can also not include the rigid flange 3412.

[0118] On the basis of the above-mentioned embodiments, please continue to refer to Figure 8 , Figure 9 and Figure 10 , Figure 10 is a sectional view of the damping structure 34 shown in Figure 8 at the B-B line. The flexible member 342 includes a flexible cylinder 3421 and a flexible flange 3422. The flexible cylinder 3421 is located in the fixing groove 2111. The flexible cylinder 3421 surrounds the outer periphery of the first cylinder 3411 and is connected with the first cylinder 3411.

[0119] When the user applies a force to the display surface of the display screen 11, the force transmitted to the second rotating member 32 will be transmitted to the flexible cylinder 3421 through the first cylinder 3411. The first cylinder 3411 will produce a small amount of deflection in the circumferential direction of the flexible cylinder 3421, so that the flexible cylinder 3421 is subjected to a shear force in the circumferential direction. The flexible cylinder 3421 quickly absorbs the kinetic energy of the small amount of deflection of the second rotating member 32 transmitted to the flexible cylinder 3421 by utilizing the damping characteristics, so as to realize the damping of the flexible cylinder 3421 in the circumferential direction.

[0120] Thus, the above-mentioned arrangement of the flexible cylinder 3421 facilitates the flexible cylinder 3421 to absorb the kinetic energy of the second rotating member 32 transmitted to the first cylinder 3411, and plays a good damping role.

[0121] On this basis, the end of the first cylinder 3411 distal to the first fixed hole 323 is located in the flexible cylinder 3421. It can be understood that when the user applies force to the display surface of the display screen 11, the force transmitted to the second rotating member 32 will be transmitted to the flexible cylinder 3421 through the first cylinder 3411. Due to the existence of the above-mentioned shearing force, the flexible cylinder 3421 will deform to a certain extent. In this way, the end of the first cylinder 3411 located in the flexible cylinder 3421 can or at least to a certain extent abut against the inner wall of the flexible cylinder 3421, and in this state, the flexible cylinder 3421 deforms in the axial direction to quickly absorb the kinetic energy of the second rotating member 32 transmitted to the flexible cylinder 3421, thereby achieving shock absorption in the axial direction. In addition, the flexible cylinder 3421 can act as an external flexible protective barrier for the first cylinder 3411, preventing the first cylinder 3411 from making hard contact with the internal components of the keyboard host 2, avoiding the transmission of the force transmitted to the first rigid member 341 to other structures of the keyboard host 2, and improving the shock absorption effect.

[0122] It should be noted here that "the end of the first cylinder 3411 distal to the first fixed hole 323 is located in the flexible cylinder 3421" means that the end of the first cylinder 3411 distal to the first fixed hole 323 does not exceed the end face of the flexible cylinder 3421 distal to the first fixed hole 323.

[0123] Please continue to refer to Figure 7 , Figure 8 and Figure 9 , the other end of the screw rod 3442 (i.e., the end of the screw rod 3442 distal to the head 3441) is located in the flexible cylinder 3421. In this way, the flexible cylinder 3421 can be used to block the hard contact between the end of the screw rod 3442 located in the flexible cylinder 3421 and other structures inside the keyboard host 2, avoid the transmission of the force transmitted to the first rigid member 341 to other structures of the keyboard host 2, and improve the shock absorption effect.

[0124] It should be noted here that "the other end of the screw rod 3442 is located in the flexible cylinder 3421" means that the other end of the screw rod 3442 does not exceed the end face of the flexible cylinder 3421 distal to the first fixed hole 323.

[0125] Please continue to refer to Figure 7 , Figure 8 and Figure 9 , the end of the flexible cylinder 3421 distal to the first fixed hole 323 is open, and thus the structure of the flexible member 342 is simple. Of course, it can be understood that in other embodiments, the end of the flexible cylinder 3421 distal to the first fixed hole 323 can also be provided with a blocking wall (not shown) for blocking the flexible cylinder 3421. Figure 7The flexible member 342 is arranged between the first shell 21 and the rigid flange 3412, so as to prevent the rigid flange 3412 from being in hard contact with the components inside the keyboard host 2.

[0126] Please continue to refer to Figure 7 、 Figure 8 and Figure 9 The flexible flange 3422 is arranged at one end of the flexible cylinder 3421 close to the rigid flange 3412. The flexible flange 3422 is fixedly connected with the flexible cylinder 3421. The flexible flange 3422 is arranged on the side of the rigid flange 3412 close to the first cylinder 3411 and is stacked with the rigid flange 3412. In this way, compared with the damping effect of only using the flexible cylinder 3421, the flexible flange 3422 can be used to separate the second shell 21 from the rigid flange 3412, so as to prevent the rigid flange 3412 from contacting the second shell 21, facilitate the flexible flange 3422 to absorb the kinetic energy of the second rotating member 32 transmitted to the rigid flange 3412, improve the damping effect, and increase the structural strength of the flexible member 342 by arranging the flexible flange 3422.

[0127] For example, the flexible member 342 can be an integral part, that is, the flexible cylinder 3421 and the flexible flange 3422 are connected as an integral part. In this way, on the one hand, the flexible member 342 can be disassembled as a whole, which is convenient for maintenance and replacement; on the other hand, the processing technology of the flexible member 342 is simplified, the processing efficiency of the flexible member 342 is improved, and the processing cost of the flexible member 342 is reduced. Of course, it can be understood that in other embodiments, the flexible cylinder 3421 and the flexible flange 3422 can also be assembled and fixed, for example, the fixing modes of the two include but are not limited to welding, bonding or clamping, etc.

[0128] It is worth noting that the foregoing is described by taking the flexible member 342 as an example which includes the flexible cylinder 3421 and the flexible flange 3422. However, the structure of the flexible member 342 is not limited thereto, and in other embodiments, the flexible member 342 can also not include the flexible flange 3422.

[0129] On the basis of any of the above embodiments including the damping structure 34, please continue to refer to Figures 7-9 The damping component further includes a second rigid member 343. The second rigid member 343 has a second external thread 3431a. The inner circumferential wall of the fixing groove 2111 has a third internal thread 2111a. The second external thread 3431a cooperates with the third internal thread 2111a. In this way, the connection mode of the thread connection is simple, easy to assemble and disassemble, and convenient for maintenance; and the external thread of the second rigid member 343 and the internal thread on the protruding part 211 are convenient for processing and manufacturing.

[0130] Of course, the connection manner of the second rigid piece 343 and the keyboard host 2 is not limited to this, in other embodiments, when the protruding part 211 is a plastic part, the protruding part 211 and the second rigid piece 343 can be connected as a whole, for example, the protruding part 211 and the second rigid piece 343 are connected as a whole by using a secondary injection molding process. Specifically, in the process of processing the protruding part 211, the damping structure 34 or the second rigid piece 343 can be pre-buried in the mold, and the plastic material is injected in the mold, and the plastic material can form the protruding part 211 which is attached to the surface of the second rigid piece 343 after cooling.

[0131] In order to improve the structural strength of the second rigid piece 343, the second rigid piece 343 can be a metal part. For example, the second rigid piece 343 is an aluminum alloy part, a magnesium alloy part or a stainless steel part. The metal part has the characteristics of high strength and high hardness, and by setting the second rigid piece 343 as a metal part, it is beneficial to improve the connection strength of the second rigid piece 343 and the keyboard host 2.

[0132] Please continue to refer to Figure 7 , Figure 8 and Figure 9 , the second rigid piece 343 includes a second cylinder 3431. The outer periphery of the second cylinder 3431 has a second external thread 3431a.

[0133] The second cylinder 3431 surrounds the outer periphery of the flexible cylinder 3421 and the first cylinder 3411. The rigid flange 3412 is located on the side of the second cylinder 3431 adjacent to the second rotating piece 32 in the axial direction. The surface of the rigid flange 3412 facing away from the first cylinder 3411 has a bit fitting groove 3413.

[0134] Since the second cylinder 3431 surrounds the outer periphery of the first cylinder 3411, the axial directions of the first cylinder 3411 and the second cylinder 3431 are the same, for example, the center axes of the two are collinear. In addition, the outer periphery of the second cylinder 3431 is provided with the second external thread 3431a. Therefore, during the assembly of the foldable device 100 by the production line worker, the bit (such as a screwdriver, etc.) can be matched with the bit fitting groove 3413 to rotate the damping structure 34, so that the second external thread 3431a and the third internal thread 2111a can be matched, and the damping structure 34 can be locked into the fixing groove 2111 by the bit, which is convenient to operate and can improve the assembly effect.

[0135] For example, the shape of the bit fitting groove 3413 includes but is not limited to "+" type, "-" type, key type or other shapes, which are not limited in the present application.

[0136] On this basis, in some embodiments, please continue to refer to Figure 7 , Figure 8 and Figure 9The surface of the flexible flange 3422 opposite to the rigid flange 3412 is fixed on the end face of the axial one end of the second cylinder 3431.

[0137] In this way, the flexible flange 3422 can separate the second housing 21 from the rigid flange 3412, avoiding the contact between the rigid flange 3412 and the second housing 21, facilitating the flexible flange 3422 to absorb the kinetic energy transmitted by the second rotating member 32 to the rigid flange 3412, and improving the damping effect. In addition, the flexible flange 3422 increases the structural strength of the flexible member 342.

[0138] Please continue to refer to Figure 8 and Figure 9 The second rigid member 343 further comprises a limiting protrusion 3432. The limiting protrusion 3432 is arranged on the end face of the axial one end of the second cylinder 3431. Specifically, the limiting protrusion 3432 is arranged on the end face of the axial one end of the second cylinder 3431 facing the flexible flange 3422.

[0139] The rigid flange 3412 is provided with a first avoiding gap 3412a. The flexible flange 3422 is provided with a second avoiding gap 3422a. Based on the stacked arrangement of the rigid flange 3412 and the flexible flange 3422, the first avoiding gap 3412a and the second avoiding gap 3422a are axially opposite to each other on the first cylinder 3411. Thus, the limiting protrusion 3432 can be fitted in the first avoiding gap 3412a and the second avoiding gap 3422a.

[0140] In this way, the limiting protrusion 3432 can limit the first rigid member 341 and the flexible member 342 in the circumferential direction of the first cylinder 3411, preventing the first rigid member 341 and the flexible member 342 from being deflected in the circumferential direction relative to the second rigid member 343, thereby avoiding the tearing of the flexible cylinder 3421 due to deflection. For example, when the damping structure 34 makes the second external thread 3431a cooperate with the third internal thread 2111a, the first rigid member 341 and the flexible member 342 are prevented from being deflected in the circumferential direction relative to the second rigid member 343, ensuring the damping effect of the damping structure 34.

[0141] For example, the limiting protrusion 3432, the first avoiding gap 3412a and the second avoiding gap 3422a are all multiple, one limiting protrusion 3432, one first avoiding gap 3412a and one second avoiding gap 3422a correspond to each other. In this way, it is beneficial to further improve the limiting effect of the limiting protrusion 3432 on the first rigid member 341 and the flexible member 342 in the circumferential direction of the first cylinder 3411.

[0142] Of course, the present application is not limited thereto, and in other embodiments, the limiting protrusion 3432, the first avoiding gap 3412a, and the second avoiding gap 3422a can also each be one.

[0143] Exemplarily, the second rigid piece 343 can be a one-piece, that is, the second cylinder 3431 and the limiting protrusion 3432 are connected as one. In this way, on the one hand, the second rigid piece 343 can be disassembled as a whole, facilitating maintenance and replacement; on the other hand, the processing technology of the second rigid piece 343 is simplified, the processing efficiency of the second rigid piece 343 is improved, and the processing cost of the second rigid piece 343 is reduced. Of course, it can be understood that in other embodiments, the second cylinder 3431 and the limiting protrusion 3432 can also be assembled and fixed, for example, the fixing modes of the two include but are not limited to welding, bonding, or clamping, etc.

[0144] In some embodiments of the present application, the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 are one-piece. In this way, on the one hand, the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 can be disassembled as a whole, facilitating maintenance and replacement; on the other hand, the processing technology of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is simplified, the processing efficiency of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is improved, and the processing cost of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is reduced. For example, a secondary injection molding process is adopted to realize the connection of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 as one. Specifically, in the process of processing the shock-absorbing structure 34, the first rigid piece 341 and the second rigid piece 343 can be pre-buried in a mold, and plastic material is injected in the mold, and the plastic material can form the flexible piece 342 after cooling, which is attached to the surface of the first rigid piece 341 and the second rigid piece 343.

[0145] In some embodiments of the present application, the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 are one-piece. In this way, on the one hand, the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 can be disassembled as a whole, facilitating maintenance and replacement; on the other hand, the processing technology of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is simplified, the processing efficiency of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is improved, and the processing cost of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 is reduced. For example, a secondary injection molding process is adopted to realize the connection of the first rigid piece 341, the second rigid piece 343, and the flexible piece 342 as one. Specifically, in the process of processing the shock-absorbing structure 34, the first rigid piece 341 and the second rigid piece 343 can be pre-buried in a mold, and plastic material is injected in the mold, and the plastic material can form the flexible piece 342 after cooling, which is attached to the surface of the first rigid piece 341 and the second rigid piece 343.

[0146] It is worth noting that the foregoing is described by taking the shock-absorbing structure 34 as an example, which includes the second rigid piece 343, the second rigid piece 343 is fixedly connected with the flexible piece 342, and the shock-absorbing structure 34 is fixedly connected with the keyboard host 2 by means of the second rigid piece 343. In other embodiments, the shock-absorbing structure 34 can also not include the second rigid piece 343.

[0147] In order to objectively evaluate the technical effects of the shock-absorbing structure 34 in the above embodiments of the present application, please refer to Figure 11 , Figure 11Waveform diagrams of the shock-absorbing effect of the comparative example and the experimental example. In the comparative example, the foldable device 100 used is the foldable device 100 shown in FIG. 1, and in the experimental example, the foldable device 100 used is the foldable device 100 shown in FIG. 2. By comparing the experimental example with the comparative example, it can be found that in the experimental example, the amplitude of the display 1 is significantly smaller than that of the display 1 in the comparative example. Therefore, compared with not setting the shock-absorbing structure 34, the shock-absorbing effect of the foldable device 100 is significantly better than that of the comparative example. Figure 6 Figure 7 In the experimental example, the foldable device 100 used is the foldable device 100 shown in FIG. 2. By comparing the experimental example with the comparative example, it can be found that in the experimental example, the amplitude of the display 1 is significantly smaller than that of the display 1 in the comparative example. Therefore, compared with not setting the shock-absorbing structure 34, the shock-absorbing effect of the foldable device 100 is significantly better than that of the comparative example.

[0148] In any of the above embodiments, please refer back to Figure 4 and Figure 5 , the damping assembly 33 includes a friction pad 331, an elastic structural member 332, and an adjusting nut 333.

[0149] The friction pad 331 is fixedly connected to the rotating shaft 311 and can rotate with the rotating shaft 311. The friction pad 331 is in the form of a sheet. For example, the friction pad 331 is in the form of a circular sheet. One side of the friction pad 331 is used to abut against the second rotating member 32. In this way, during the rotation of the friction pad 331 with the rotating shaft 311, the friction pad 331 and the second rotating member 32 abut against each other to form damping.

[0150] In order to facilitate the assembly of the friction pad 331 with the rotating shaft 311 and ensure that the friction pad 331 can rotate with the rotating shaft 311, the friction pad 331 is provided with a first assembly hole 3311 for cooperating with the rotating shaft 311. The first assembly hole 3311 penetrates the friction pad 331 along the X-axis direction, and the shape and size of the first assembly hole 3311 are adapted to the shape and size of the cross section of the rotating shaft 311.

[0151] The elastic structural member 332 is sleeved on the shaft body of the rotating shaft 311 and is used to apply a force to the friction pad 331 towards the second rotating member 32, so that the friction pad 331 and the second rotating member 32 remain in contact.

[0152] In some embodiments, the elastic structural member 332 is a disc spring set, which includes a plurality of disc spring pieces 3321 arranged in the axial direction of the rotating shaft 311. The disc spring piece 3321 is provided with a second assembly hole 3321a, and the disc spring piece 3321 is sleeved outside the shaft body of the rotating shaft 311 by means of the second assembly hole 3321a. For example, the second assembly hole 3321a is a circular hole. When the rotating shaft 311 rotates, the elastic structural member 332 does not rotate with the rotating shaft 311. It can be understood that in other embodiments, the elastic structural member 332 can also be a spring, a torsion spring, etc.

[0153] ​The adjusting nut 333 is screwed on the rotating shaft 311 and located on the side of the elastic structure 332 away from the friction pad 331. By rotating the adjusting nut 333, the elastic structure 332 can be compressed to apply a force to the friction pad 331 towards the second rotating member 32. By rotating the adjusting nut 333, the pre-tightening force of the elastic structure 332 can be adjusted, and thus the initial rotating damping provided by the rotating shaft mechanism 3 can be adjusted, so as to meet the requirements of different damping scenarios and have a wide range of applications.

[0154] Further, the damping assembly 33 further comprises a stop washer 334 fixedly connected to the rotating shaft 311 and located between the adjusting nut 333 and the elastic structure 332. The opposite surfaces of the stop washer 334 are in contact with and abut against the adjusting nut 333 and the elastic structure 332, respectively. The stop washer 334 is in the shape of a sheet. The stop washer 334 is provided with a third assembly hole 3341, which is shaped to match the shape of the body portion. In this way, when the rotating shaft 311 rotates relative to the second rotating member 32, the stop washer 334 and the adjusting nut 333 are driven to rotate together. In the embodiment, by providing the stop washer 334, the adjusting nut 333 can be prevented from loosening, the connection stability between the adjusting nut 333 and the rotating shaft 311 can be improved, and thus the structural stability of the rotating shaft mechanism 3 can be improved.

[0155] Optionally, the stop washer 334 has the same structure as the friction pad 331. In this way, the structure of the rotating shaft mechanism 3 can be simplified.

[0156] It can be understood that the structure of the damping assembly 33 is not limited thereto, as long as it can provide rotating damping during the rotation of the rotating shaft 311.

[0157] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0158] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
