Technical Field

[0001] This application relates to, but is not limited to, the field of electronic devices, and in particular to a rotating shaft device and an electronic device. Background Technology

[0002] In related technologies, electronic devices are folded or unfolded through a hinge mechanism. However, the hinge mechanism is prone to jamming when the assembly precision is high, while low assembly precision will cause it to wobble during movement and have poor stability when hovering. Summary of the Invention

[0003] The rotating shaft device and electronic equipment provided in this application have high motion accuracy and hovering stability.

[0004] In a first aspect, embodiments of this application provide a rotating shaft device, including a moving component, a trajectory path component, and a limiting component; the trajectory path component is used to provide a trajectory path for the moving component; the limiting component is used to limit the movement of the moving component on the trajectory path; wherein, the moving component moves on the trajectory path under the action of a driving force, and the movement trajectory of the moving component is matched with the trajectory path based on the limiting component.

[0005] The rotating shaft device provided in this application embodiment is provided with a trajectory path component to provide a trajectory path for the moving part, so that the moving part can move along the trajectory path. However, due to the presence of assembly errors or the action of external forces, the moving part may deviate from the trajectory path during movement, or the moving part may wobble when hovering. Therefore, the rotating shaft device of this application is also provided with a limiting component. The limiting component can restrict the movement of the moving part on the trajectory path. When the moving part moves along the trajectory path under the action of driving force, the limiting component makes the movement trajectory of the moving part match the trajectory path, thereby reducing the wobble of the moving part and improving the movement accuracy or hovering stability of the rotating shaft device.

[0006] In one possible implementation of this application, the trajectory path component includes a first trajectory path component and a second trajectory path component. Under the action of the driving force, the first part of the moving component moves along the first trajectory path of the first trajectory path component, and the second part of the moving component moves along the second trajectory path of the second trajectory path component.

[0007] In one possible implementation of this application, the trajectory path is an arc-shaped path, and the limiting member restricts the movement of the moving member on one of the first and second trajectory paths.

[0008] In one possible implementation of this application, the radius of the arc path of the first trajectory path is different from the radius of the arc path of the second trajectory path.

[0009] In one possible implementation of this application, the rotating shaft device further includes a rotating shaft assembly for providing torque.

[0010] In one possible implementation of this application, the rotating shaft device further includes a rotating shaft assembly for providing support force at the target position where the device stops on the trajectory path.

[0011] In one possible implementation of this application, the rotating shaft device further includes a transmission assembly for transmitting driving force to the moving component, and the second trajectory path component belongs to the transmission assembly.

[0012] In one possible implementation of this application, the first trajectory path component is a trajectory hole on the base of the rotating shaft device; wherein, under the action of the driving force, the first part of the moving component moves out on the second trajectory path along with the second part of the moving component and moves into the first trajectory path.

[0013] Secondly, embodiments of this application provide an electronic device, including a first body and a second body that can be unfolded or folded relative to each other. The first body and the second body are hinged together by a pivot device, wherein the pivot device includes a moving member, a trajectory path member, and a limiting member. The first body and / or the second body are used to drive the moving member to move; the trajectory path member is used to provide a trajectory path for the moving member; the limiting member is used to limit the stopping position of the moving member on the trajectory path; wherein the moving member moves on the trajectory path under the action of the first body and / or the second body, and the stopping position of the moving member on the trajectory path based on the limiting member matches the trajectory path.

[0014] The electronic device provided in this application embodiment has a limiting component that can restrict the stopping position of the first body and / or the second body on the trajectory path, so that the stopping position of the first body and / or the second body matches the trajectory path, thereby improving the stability of the first body and the second body when hovering.

[0015] Thirdly, embodiments of this application provide an electronic device, including a first body and a second body that can be relatively unfolded or folded. The first body and the second body are hinged together by a pivot device, wherein the pivot device includes a moving member, a trajectory path member, and a limiting member. The first body and / or the second body are used to drive the moving member to move; the trajectory path member is used to provide a trajectory path for the moving member; the limiting member is used to restrict the movement of the moving member on the trajectory path; wherein the moving member moves on the trajectory path under the action of the first body and / or the second body, and the movement trajectory of the moving member is matched with the trajectory path based on the limitation of the limiting member.

Detailed Implementation

[0036] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the specific technical solutions of the present application will be further described in detail below in conjunction with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application but are not intended to limit the scope of the present application.

[0037] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "multiple" means two or more.

[0038] In addition, in the embodiments of the present application, directional terms such as "up", "down", "left" and "right" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they may change accordingly according to changes in the orientation of the components in the drawings.

[0039] In the embodiments of the present application, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integrated connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0040] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0041] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be interpreted as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0042] This application provides an electronic device, which can be any device including a hinge. Any electronic device that requires a hinge for rotation is included within the scope of this application. Examples include: laptops, foldable phones, tablets with rotating keyboards, servers, all-in-one computers, etc.

[0043] Reference Figure 1Taking a foldable screen mobile phone as an example, the electronic device includes a first body 010 and a second body 020. The first body 010 and the second body 020 are hinged together by a pivot device. The electronic device also includes a flexible screen 030 covering the first body 010 and the second body 020. The first body 010 and the second body 020 can be folded or unfolded relative to each other by the pivot device.

[0044] Furthermore, this application embodiment also provides a rotating shaft device, referring to... Figure 2 and Figure 3 The rotating shaft device includes a moving part 230, a trajectory path part, and a limiting part 240; the trajectory path part is used to provide a trajectory path for the moving part 230; the limiting part 240 is used to limit the movement of the moving part 230 on the trajectory path; wherein, the moving part 230 moves on the trajectory path under the action of a driving force, and the movement trajectory of the moving part 230 is matched with the trajectory path based on the limiting part 240.

[0045] The rotating shaft device provided in this application embodiment is provided with a trajectory path component to provide a trajectory path for the moving component 230, enabling the moving component 230 to move along the trajectory path. However, due to assembly errors or external forces, the moving component 230 may deviate from the trajectory path during movement. Therefore, the rotating shaft device of this application is also provided with a limiting component 240. The limiting component 240 can restrict the movement of the moving component 230 on the trajectory path. When the moving component 230 moves along the trajectory path under the action of driving force, the limiting component 240 makes the movement trajectory of the moving component 230 match the trajectory path, thereby reducing the shaking of the moving component 230 during movement, improving the movement accuracy of the rotating shaft device, and making the first body 010 and the second body 020 more smoothly fold or unfold relative to each other.

[0046] Furthermore, when the first body 010 and the second body 020 are hovering relative to each other, for example, when the included angle between the first body 010 and the second body 020 is 120°, due to the fit gap between the moving part 230 and the trajectory path part, when the first body 010 or the second body 020 is subjected to external force, the moving part 230 will be driven to deviate from the trajectory path provided by the trajectory path part, thereby causing the first body 010 and the second body 020 to shake relative to each other, affecting the use of electronic devices. Therefore, the rotating shaft device of this application is provided with a limiting part 240, which is used to limit the stopping position of the moving part 230 on the trajectory path, so that the stopping position of the moving part 230 does not deviate from the trajectory path, thereby reducing the possibility of the first body 010 and the second body 202 shaking under force when hovering relative to each other.

[0047] The specific structure of the rotating shaft device is not limited in this application; refer to [reference]. Figure 2 and Figure 3In one possible embodiment of this application, the rotating shaft device includes a connecting seat 100 and two sets of rotating mechanisms disposed on the connecting seat 100. The trajectory path component can be the connecting seat 100. Each set of rotating mechanisms includes at least one moving component 230 and at least one limiting component 240. The first body 010 and the second body 020 of the electronic device are rotatably connected to the connecting seat 100 through a set of rotating mechanisms. Optionally, the two sets of rotating mechanisms have the same structure and are symmetrically arranged. For ease of explanation, the rotating mechanism connected to the first body 010 will be used as an example in the following description.

[0048] It should be noted that when the moving part 230 moves along a single trajectory path, the motion accuracy can be improved by increasing the assembly accuracy. However, when the moving part 230 moves along multiple different trajectory paths simultaneously, if multiple moving parts 230 and multiple trajectory path parts adopt high assembly accuracy, it is easy for the moving part 230 to jam. Therefore, this problem is solved by setting a limiting part 240 on the trajectory path. For example, when there are two different trajectory path parts, one trajectory path can be assembled with the moving part 230 with high accuracy, and the other trajectory path part can be assembled with the moving part 230 with low accuracy. A limiting part 240 is set between the trajectory path part with lower assembly accuracy and the moving part 230. This setting can reduce the risk of the moving part 230 jamming during movement and allow the moving part 230 to move along two different trajectory paths simultaneously.

[0049] Optionally, in one possible embodiment of this application, the trajectory path component includes a first trajectory path component 121 and a second trajectory path component 223. Under the action of the driving force, the first part of the moving component 230 moves according to the first trajectory path of the first trajectory path component 121, and the second part of the moving component 230 moves according to the second trajectory path of the second trajectory path component 223.

[0050] Reference Figure 3 and Figure 5 In one possible embodiment of this application, the connecting seat 100 includes a first base 120, at least a portion of which forms a first trajectory path member 121. Furthermore, the rotating mechanism includes a track member 220, at least a portion of which forms a second trajectory path member 223. A moving member 230 is disposed between the track member 220 and the first base 120. (Refer to...) Figure 8 and Figure 9 The moving part 230 includes a third base 231, and a first moving part 233 and a second moving part 232 fixedly connected to the third base 231. The first part of the moving part 230 is the first moving part 233, and the second part of the moving part 230 is the second moving part 232. The first moving part 233 is connected to the first trajectory path member 121, and the second moving part 232 is connected to the second trajectory path member 223.

[0051] It should be noted that the first trajectory path and the second trajectory path can be the same type of motion or different types of motion. For example, the first trajectory path and the second trajectory path can both be straight paths; or the first trajectory path and the second trajectory path can both be curved paths; or the first trajectory path can be a curved path and the second trajectory path can be a straight path.

[0052] Reference Figure 3 In one possible embodiment of this application, both the first trajectory path and the second trajectory path are arc-shaped paths, and the limiting member 240 restricts the movement of the moving member 230 on one of the first and second trajectory paths. This reduces both the jerking and wobbling of the moving member 230 when it moves along both paths simultaneously, improving movement accuracy and hovering stability. Specifically, the first moving part 233 and the first trajectory path member 121 are rotatably connected, and the second moving part 232 and the second trajectory path member 223 are rotatably connected. Optionally, the rotation axis of the second moving part 232 relative to the second trajectory path member 223 is parallel to the rotation axis of the first moving part 233 relative to the first trajectory path member 121.

[0053] Optionally, the radius corresponding to the arc path of the first trajectory path is different from the radius corresponding to the arc path of the second trajectory path. The rotation radius of the first moving part 233 and the first trajectory path component 121 is larger than the rotation radius of the second moving part 232 and the second trajectory path component 233. The mating surface size of the second moving part 232 and the second trajectory path component 233 is smaller, which facilitates the use of higher precision mating. The mating surface size of the first moving part 233 and the first trajectory path component 121 is larger, which allows for lower precision mating. A limiting component 240 is provided between the first moving part 233 and the first trajectory path component 121. When the moving part 230 moves simultaneously relative to the first trajectory path component 121 and the second trajectory path component 233, there is a speed difference, thereby ensuring that the moving part 230 can move simultaneously on the first trajectory path and the second path without jamming.

[0054] This application does not limit the connection form between the first moving part 233 and the first trajectory path member 121. For example, the first trajectory path member 121 forms an arc-shaped guide rail, and the first moving part 233 moves along the arc-shaped guide rail; see reference. Figure 6 and Figure 8 In one possible embodiment of this application, the first trajectory path member 121 is formed with a semi-circular first limiting groove 121a, and the first moving part 233 is formed with a semi-circular mating surface. The first moving part 233 extends into the first limiting groove 121a, and the two rotate relative to each other. That is, the first trajectory path member 121 is a trajectory hole on the base of the rotating shaft device.

[0055] To prevent the first moving part 233 from dislodging from the first limiting groove 121a, refer to Figure 6 and Figure 8 In one possible embodiment of this application, a first sliding groove 121b is formed on the side wall of the first limiting groove 121a along the axial direction of the first rotation axis 310. The extension direction of the first sliding groove 121b is arranged along a semi-circular arc. A first limiting flange 233a is provided on the side wall of the first moving part 233 along the axial direction of the first rotation axis 310. The shape of the first limiting flange 233a is adapted to the first sliding groove 121b. The first limiting flange 233a and the first sliding groove 121b are slidably connected to limit the first moving part 233 in the first trajectory path member 121.

[0056] Furthermore, this application does not limit the connection form of the second motion part 232 and the second trajectory path member 223, as referred to Figure 5 and Figure 9 In one possible embodiment of this application, the track component 220 further includes a limiting block 224, which is snapped and fixed at the position of the second track path component 223. The limiting block 224 and the second track path component 223 are both arc-shaped and close to each other, forming a second sliding groove 225 between them. The second sliding groove 225 is an arc-shaped channel, and the second moving part 232 extends into the second sliding groove 225 to be rotatably connected to the second track path component 223.

[0057] Based on this, this application does not limit the function of the limiting member 240. The limiting member 240 can be an elastic member 420, such as a spring or a sheet, or it can be a non-elastic member 420. The limiting member 240 can be disposed between the first moving part 233 and the first trajectory path member 121, or it can be disposed between the second moving part 232 and the second trajectory path member 223.

[0058] Reference Figure 2 and Figure 3 In one possible embodiment of this application, the limiting member 240 is a spring sheet, and the limiting member 240 is disposed between the first moving part 233 and the first trajectory path member 121. The moving part 230 and the second trajectory path member 223 are fitted with high precision. The two ends of the limiting member 240 abut against the moving part 230 and the first base 120 respectively, thereby compensating for the fitting gap between the moving part 230 and the first base 120. Since the limiting member 240 is elastic, the moving part 230 and the first base 120 at both ends can be subjected to force, thereby reducing the possibility of relative shaking between the moving part 230 and the first base 120. Moreover, the larger fitting gap can also reduce the risk of jamming between the moving part 230 and the first base 120.

[0059] Specific reference Figure 7The limiting member 240 includes a connecting end 241a and an actuating end 241b. The connecting end 241a of the limiting member 240 is fixedly connected to one of the moving member 230 and the first base 120, while the actuating end 241b of the limiting member 240 abuts against the other of the moving member 230 and the first base 120. This arrangement allows the limiting member 240 to apply force toward the moving member 230 and the first base 120, thereby reducing the relative sway between them. Furthermore, the fact that the limiting member 240 is fixed to one of the moving member 230 and the first base 120 prevents the limiting member 240 from falling out of the mating gap between the moving member 230 and the first base 120.

[0060] To make the limiting component 240 more compact and save space, refer to Figure 12 and Figure 13 In one possible embodiment of this application, the mating size of the moving part 230 corresponding to the first base 120 is smaller than the mating size of the first base 120 corresponding to the moving part 230. That is, the moving part 230 slides on the first base 120, and the connecting end 241a of the limiting part 240 is fixedly connected to the moving part 230. With this configuration, the limiting part 240 is connected to a component with a smaller mating size, which can maintain the contact between the limiting part 240 and the first base 120 during the movement process without having to set an excessively large limiting part 240.

[0061] There are several ways to fix the connecting end 241a of the limiting member 240 and the moving member 230. For example, the connecting end 241a and the moving member 230 are snapped together; the connecting end 241a and the moving member 230 are glued together; or the connecting end 241a and the moving member 230 are connected and fixed by fasteners such as screws.

[0062] To facilitate the disassembly, assembly, and maintenance of the limiting component 240, refer to... Figure 7 and Figure 8 In one possible embodiment of this application, the connecting end 241a is provided with a first snap-fit ​​portion 242, and the moving member 230 is provided with a second snap-fit ​​portion 234. The first snap-fit ​​portion 242 and the second snap-fit ​​portion 234 are snap-fitted and adapted to snap-fit ​​and fix the limiting member 240 and the moving member 230.

[0063] Specifically, the second latching part 234 is a latching post disposed on the moving member 230. The axial direction of the latching post is parallel to the axial direction of the first rotating shaft 310. The limiting member 240 includes a fourth base 241. The first latching part 242 includes a first protrusion 242a disposed on the fourth base 241. The first protrusion 242a is located on the side of the fourth base 241 away from the first base 120. The first protrusion 242a and the fourth base 241 form a latching groove 242b. The opening size of the latching groove 242b is smaller than the radial size of the latching post. Since both the first protrusion 242a and the fourth base 241 are elastic, the opening size of the latching groove 242b can change with the elastic deformation of the first latching part 242, so that the second latching part 234 extends into the first latching part 242.

[0064] The snap-fit ​​post can be a cylinder, a triangular prism, a hexagonal prism, etc. For ease of connection between the second snap-fit ​​part 234 and the first snap-fit ​​part 242, refer to... Figure 7 and Figure 8 In one possible embodiment of this application, the locking post is cylindrical. To prevent the limiting member 240 from rotating around the locking post, optionally, a second protrusion 242c is also provided on the first locking portion 242. The second protrusion 242c abuts against the moving member 230 to reduce the possibility of relative rotation between the limiting member 240 and the moving member 230. This fixes the limiting member 240 to the moving member 230.

[0065] To reduce the clearance between the moving part 230 and the first base 120, and to make the assembly structure of the two occupy less space, refer to Figure 8 In one possible embodiment of this application, a receiving groove 235 is provided on the third base 231. The receiving groove 235 is located on the side of the third base 231 facing the first base 120. The second snap-fit ​​part 234 is disposed in the receiving groove 235. The first snap-fit ​​part 242 extends into the receiving groove 235 and snaps and fixes the second snap-fit ​​part 234. This arrangement can avoid the connecting end 241a of the limiting member 240 occupying the space of the mating gap, making the structure more compact.

[0066] It should be noted that the connecting end 241a and the actuating end 241b are arranged along the extension direction of the limiting member 240. This application does not restrict the extension direction of the limiting member 240. Optionally, the extension direction of the limiting member 240 can be perpendicular to the movement direction of the moving member 230; or, the extension direction of the limiting member 240 and the movement direction of the moving member 230 can be arranged at an angle, as long as it is ensured that the connecting end 241a and the actuating end 241b of the limiting member 240 can apply elastic force to the moving member 230 and the first base 120 respectively.

[0067] In order to reduce the mating clearance and reduce the size of the assembly structure of the moving part 230 and the first base 120, optionally, in one possible embodiment of this application, the extension direction of the limiting member 240 and the movement direction of the moving part 230 are set at an angle, and the angle between the two can be any acute angle, so that the limiting member 240 can obtain a large amount of elastic deformation without increasing the size of the mating clearance, making the assembly structure of the moving part 230, the first base 120 and the limiting member 240 more compact.

[0068] Reference Figure 14 and Figure 15 In another possible embodiment of this application, the limiting member 240 is a support block disposed on the connecting seat 100. The limiting member 240 and the connecting seat 100 are fixedly connected. The limiting member 240 has a first working surface 243 on the side facing the moving member 230. The moving member 230 includes a second working surface 236 that abuts against the first working surface 243. The second working surface 236 is located in the first moving part 233. The limiting member 240 and the moving member 230 slide relative to each other through the first limiting surface and the second limiting surface to restrict the moving member 230 from moving along the trajectory path of the first trajectory path member 121.

[0069] The limiting component 240 is made of a material with good plasticity, and its elastic modulus is between 1 GPa and 2 GPa, such as 1 GPa, 1.5 GPa, 2 GPa, etc. If the elastic modulus of the limiting component 240 is too high, it will be difficult to deform, resulting in excessive relative motion resistance between the limiting component 240 and the moving component 230, which may easily cause the moving component 230 to jam. If the elastic modulus of the limiting component 240 is too low, it will be easily deformed under stress, failing to perform its limiting function, and the material will be too soft and easily worn. Optionally, the limiting component 240 can be made of polyoxymethylene (POM) or rigid plastic, etc.

[0070] Based on this, the limiting member 240 can be fixedly connected to the connecting seat 100 by means of bonding, snapping or other methods. Optionally, the first base 120 is provided with a limiting hole, and the limiting member 240 is snapped into the limiting hole so that the limiting member 240 and the connecting seat 100 are relatively fixed. The limiting member 240 abuts against the moving member 230 and the connecting seat 100 on both sides along the direction perpendicular to the first working surface 243.

[0071] Reference Figure 6 and Figure 16The first slide groove 121b has a third working surface 121c that matches the second working surface 236. The first working surface 243, the second working surface 236, and the third working surface 121c are all arc surfaces and are concentrically arranged. It should be noted that the arc radius corresponding to the first working surface 243 is 0.03mm to 0.05mm smaller than the arc radius corresponding to the third working surface 121c, so that there is a fitting gap between the moving part 230 and the groove wall of the first slide groove 121b, while the moving part 230 and the limiting part 240 abut against each other, forming a positive pressure between the moving part 230 and the limiting part 240, so that there is a certain friction between the moving part 230 and the limiting part 240, which plays a damping role. The limiting part 240 is made of a material with an elastic modulus between 1GPa and 2GPa, which can both limit the movement of the moving part 230 and have a certain elastic deformation capacity to reduce the risk of jamming when the moving part 230 moves.

[0072] Furthermore, this application does not limit the number of limiting members 240. There can be one or more limiting members 240. Multiple limiting members 240 can be arranged sequentially along the axial direction of the first rotation axis 310. By adding or removing limiting members 240, the force exerted by the limiting members 240 on the moving member 230 and the first base 120 can be adjusted. Optionally, in one possible embodiment of this application, two limiting members 240 are provided between the moving member 230 and the first base 120. The two limiting members 240 are arranged side by side along the axial direction of the first rotation axis 310 to increase the damping between the moving member 230 and the first base 120.

[0073] To facilitate the axial positioning of multiple limiting components 240 along the first rotation axis 310 and reduce the possibility of misalignment of the limiting components 240, refer to Figure 6 and Figure 10 In one possible embodiment of this application, a second limiting groove 122 is provided on the first base 120. The dimension of the limiting groove along the axial direction of the first rotation axis 310 is adapted to the dimension of the limiting member 240 along the axial direction of the first rotation axis 310. The functional end 241b of the limiting member 240 extends into the limiting groove, so that the groove wall of the limiting groove positions the limiting member 240. In addition, a sleeve can be provided on the snap post of the second snap part 234, and the sleeve abuts against the limiting member 240 to limit the limiting member 240.

[0074] It should be noted that multiple limiting structures can be provided on the first moving part 233 to be adapted to the first base 120 respectively. The multiple limiting structures can be the same or different, as shown in the reference. Figure 17The first moving part 233 also includes a second limiting flange 233b. The second limiting flange 233b and the first limiting flange 233a are arranged sequentially along the axial direction of the first rotation axis 310. The projected contours of the second limiting flange 233b and the first limiting flange 233a along the axial direction of the first rotation axis 310 are both arc-shaped. The radius of the first limiting flange 233a and the radius of the second limiting flange 233b can be the same or different. The receiving groove 235 can be disposed between the first limiting flange 233a and the second limiting flange 233b.

[0075] Since the moving parts 230 in the two rotating mechanisms are arranged opposite each other, interference is likely to occur if the first moving parts 233 in both rotating mechanisms are of large size. To make the mating surface size between the first moving part 233 and the first trajectory path member 121 larger, refer to... Figure 17 In one possible embodiment of this application, the radius of the first limiting flange 233a on the moving member 230 is smaller than the radius of the second limiting flange 233b, and the moving members 230 in the two rotating mechanisms are centrally symmetrically arranged so that the first limiting flange 233a in one rotating mechanism and the second limiting flange 233b in the other rotating mechanism move on the same plane. The smaller first limiting flange 233a can avoid the larger second limiting flange 233b, thereby allowing the second limiting flange 233b to be larger, so as to increase the mating surface between the first moving part 233 and the first base 120.

[0076] Based on this, when the limiting member 240 is a support block, the dimensions of the limiting member 240 can also be designed according to the dimensions of the limiting structure, referring to... Figure 18 In one possible embodiment of this application, the limiting member 240 includes a first limiting member 240a and a second limiting member 240b. The size of the first limiting member 240a is smaller than the size of the second limiting member 240b. The first limiting member 240a is disposed between the first limiting flange 233a and the first base 120, and the second limiting member 240b is disposed between the second limiting flange 233b and the first base 120. This ensures that both the first limiting flange 233a and the second limiting flange 233b receive adequate support.

[0077] Based on this, the pivot device also includes a pivot assembly that can provide torque. The external force required by the user needs to overcome the torque to form a driving force to improve the feel. Alternatively, the torque can drive the moving part 230 to move along the trajectory path.

[0078] In addition, the pivot device also includes a pivot assembly, which provides support force to stop at the target position on the trajectory path, thereby enabling the moving part 230 to hover at the target position. Of course, the pivot assembly can provide both torque and support force.

[0079] Reference Figure 2 and Figure 11 In one possible embodiment of this application, the rotating shaft assembly includes a first rotating shaft 310 and a second rotating shaft 320 disposed on the connecting seat 100. Both the first rotating shaft 310 and the second rotating shaft 320 are rotatably connected to the connecting seat 100, and the first rotating shaft 310 and the second rotating shaft 320 are arranged in parallel. The first rotating shaft 310 is connected to the first body 010 of the electronic device via a transmission connection, and the second rotating shaft 320 is connected to the second body 020 of the electronic device via a transmission connection. This allows the first body 010 to rotate relative to the connecting seat 100 via the first rotating shaft 310, and the second body 020 to rotate relative to the connecting seat 100 via the second rotating shaft 320, thereby enabling the first body 010 and the second body 020 to move relative to each other, thus realizing the folding and unfolding of the electronic device.

[0080] In order to enable the two device bodies to move synchronously relative to each other, refer to Figure 2 and Figure 11 In one possible embodiment of this application, a first gear 330 and a second gear 340 are also provided. The first gear 330 is drivenly connected to the first rotating shaft 310, and the central axis of the first gear 330 and the central axis of the first rotating shaft 310 are coaxially arranged. Correspondingly, the second gear 340 is drivenly connected to the second rotating shaft 320, and the central axis of the second gear 340 and the central axis of the second rotating shaft 320 are coaxially arranged. The first gear 330 and the second gear 340 mesh with each other so that the first gear 330 and the second gear 340 move synchronously.

[0081] Specifically, when the user applies a driving force to the first body 010, the driving force causes the first body 010 to rotate relative to the connecting seat 100. The first body 010 then causes the first rotating shaft 310 to rotate relative to the connecting seat 100. The first rotating shaft 310 causes the first gear 330 to rotate relative to the connecting seat 100. In turn, the first gear 330 causes the second gear 340 to rotate relative to the connecting seat 100. The second gear 340 causes the second rotating shaft 320 to rotate relative to the connecting seat 100. Finally, the second rotating shaft 320 causes the second body 020 to rotate relative to the connecting seat 100, thus facilitating the operator's use. When the user applies a driving force to the second body 020, the direction of force transmission is reversed.

[0082] Furthermore, due to the meshing transmission of the first gear 330 and the second gear 340, their rotation directions are opposite, which makes the rotation directions of the first rotating shaft 310 and the second rotating shaft 320 opposite. This makes the rotation direction of the first body 010 relative to the connecting seat 100 and the rotation direction of the second body 020 relative to the connecting seat 100 opposite. The first body 010 and the second body 020 are always moving relative to each other. That is, when the first body 010 moves toward the second body 020, the second body 020 also moves toward the first body 010. Correspondingly, when the first body 010 moves away from the second body 020, the second body 020 also moves away from the first body 010. Users can unfold or fold electronic devices more quickly.

[0083] It should be noted that the first gear 330 and the second gear 340 can mesh directly or indirectly through an intermediate gear. This application does not impose any restrictions on this. Figure 11 In one possible embodiment of this application, a third gear 350 and a fourth gear 360 are also provided. The third gear 350 meshes with the first gear 330, and the fourth gear 360 meshes with the third gear 350. The third gear 350 and the fourth gear 360 mesh so that the first gear 330 and the second gear 340 are indirectly meshed. In order to enable the first body 010 and the second body 020 to move relative to each other, the number of intermediate gears should be even.

[0084] In order to enable the electronic device to hover, so that the first body 010 and the second body 020 can be relatively fixed within a preset angle, refer to Figure 11 In one possible embodiment of this application, a damping assembly is also included. The damping assembly includes a movable member 410 and an elastic member 420. The connecting seat 100 includes a second base 130. The movable member 410 can move relative to the second base 130 along the axial direction of the first rotation shaft 310. The elastic member 420 is disposed between the movable member 410 and the second base 130. The two ends of the elastic member 420 abut against the movable member 410 and the second base 130, respectively. The elastic member 420 can apply an elastic force to the movable member 410, causing the movable member 410 to move away from the second base 130 to abut against the first gear 330, preventing the relative rotation of the first gear 330 and the connecting seat 100. Thus, the elastic force of the elastic member 420 is used to make the first body 010 hover relative to the connecting seat 100. That is, the rotating shaft assembly is used to provide support force for stopping at the target position on the trajectory path.

[0085] This application does not limit the specific form of the elastic element 420; see reference... Figure 11In one possible embodiment of this application, the movable member 410 is respectively sleeved on the first rotating shaft 310 and the second rotating shaft 320, and the movable member 410 is guided by the first rotating shaft 310 and the second rotating shaft 320. There are two elastic members 420, namely the first elastic member 421 and the second elastic member 422. The first elastic member 421 is sleeved on the first rotating shaft 310, and the second elastic member 422 is sleeved on the second rotating shaft 320, so that the force on the movable member 410 is more balanced.

[0086] In order to enable the automatic opening and closing of the first body 010 and the second body 020, refer to Figure 11 In one possible embodiment of this application, the rotating mechanism includes a first cam 430 and a second cam 440. The first cam 430 can move relative to the connecting seat 100 along the axial direction of the first rotating shaft 310. The second cam 440 is connected to the first body 010 in a transmission manner. The first cam 430 and the second cam 440 abut against each other, and the first cam 430 and the second cam 440 are provided with abutting inclined surfaces. The abutting inclined surfaces cause the interaction force of the first cam 430 and the second cam 440 to be decomposed along the tangential direction of the second cam 440, thereby driving the second cam 440 to rotate, so as to realize the automatic opening and closing of the first body 010 and the second body 020, that is, the rotating shaft assembly provides torque.

[0087] Specifically, the first cam 430 is sleeved on the first rotating shaft 310, and the first cam 430 and the moving member 410 are fixedly connected so that the first cam 430 follows the movement of the moving member 410 and slides along the axial direction of the first rotating shaft 310. The first cam 430 and the first rotating shaft 310 can also rotate relative to each other. The second cam 440 is fixedly connected to the side of the first gear 330 facing the first cam 430. The first gear 330 and the first rotating shaft 310 are connected by transmission through the first cam 430 and the second cam 440.

[0088] Based on this, when the user applies a driving force toward the first body 010, the driving force drives the first gear 330 to rotate relative to the first rotating shaft 310. The first gear 330 drives the second cam 440 to rotate relative to the first cam 430. The interaction between the abutting inclined surfaces of the first cam 430 and the second cam 440 causes the first cam 430 to drive the moving member 410 toward the second base 130, and causes the elastic member 420 to undergo elastic deformation. When the user's driving force is removed, the elastic member 420 applies an elastic force toward the moving member 410, causing the moving member 410 to undergo elastic deformation. The first cam 430 on component 410 and the second cam 440 on the first gear 330 abut against each other, thereby restricting the rotation of the second cam 440, and thus restricting the rotation of the first body 010 relative to the connecting seat 100. At this time, the first body 010 and the second body 020 are suspended relative to each other. Due to the presence of the limiting component 240, the cooperation gap between the moving component 230 and the trajectory path component can be compensated, so that the stopping position of the moving component 230 is on the trajectory path, thereby reducing the possibility of the first body 010 and the second body 202 shaking under force when suspended relative to each other.

[0089] Based on this, the rotating shaft device also includes a transmission assembly for transmitting driving force to the moving part 230, and the second trajectory path part 223 belongs to the transmission assembly.

[0090] In order for the first body 010 to be driveably connected to the first rotating shaft 310, refer to Figure 4 and Figure 11 In one possible embodiment of this application, the rotating mechanism further includes a torque arm 210, which can rotate relative to the connecting seat 100 with the first rotating shaft 310. Specifically, the connecting seat 100 includes a stop plate 110, and the torque arm 210 includes a first base 211 and a rotating shaft portion 212. The axis of the rotating shaft portion 212 is parallel to the central axis of the first rotating shaft 310. The rotating shaft portion 212 is rotatably connected to the stop plate 110, and the rotating shaft portion 212 also includes a gear portion 213. The gear portion 213 is a sector gear, and the central axis of the gear portion 213 is coaxial with the central axis of the rotating shaft portion 212. The gear portion 213 and the first gear 330 are meshed, that is, the torque arm 210 transmits power to each other through the gear portion 213 and the first gear 330.

[0091] Meanwhile, the track component 220 includes a second base 221 and a first transmission part 222 axially disposed on one side of the second base 221 along the first rotation axis 310. The second base 221 is used to be fixedly connected to the first body 010. A first guide part 214 is disposed on the side of the first base 211 near the first transmission part 222. The first transmission part 222 and the first guide part 214 are slidably connected, and the relative movement direction of the first transmission part 222 and the first guide part 214 is disposed along the axial direction perpendicular to or approximately perpendicular to the first rotation axis 310.

[0092] Based on this, the rotating mechanism also includes a support plate 250, which is fixedly connected to the side of the third base 231 away from the second base 120, as shown in the figure. Figure 12 When the electronic device is in the unfolded state, i.e., when the first body 010 and the second body 020 are on the same plane, the support plates 250 in the two rotating mechanisms are also on the same plane as the first body 010. At this time, the middle part of the flexible screen 030 lies flat on the two support plates 250. The two support plates 250, the first body 010, and the second body 020 simultaneously support the flexible screen 030, making it convenient for the user. If the electronic device changes from the unfolded state to the folded state, the first moving part 233 of the moving part 230 will gradually slide out from the first slide groove 121b, and the second moving part 232 of the moving part 230 will gradually slide into the second slide groove 225.

[0093] Reference Figure 13 When the electronic device is in a folded state, i.e., when the first body 010 and the second body 020 are in relative contact, the support plates 250 in the two rotating structures form an acute angle, creating a triangular-like accommodating space between the two support plates 250 and the first base 120. The flexible screen 030 bends into a teardrop shape within this accommodating space, allowing the flexible screen 030 to achieve a larger bending radius in the folded state, thereby improving its service life. If the electronic device changes from a folded state to an unfolded state, the first moving part 233 of the moving member 230 will gradually slide into the first sliding groove 121b, while the second moving part 232 of the moving member 230 will gradually slide out from the second sliding groove 225.

[0094] Optionally, under the action of the driving force, the first part of the moving part 230 moves out on the second trajectory path and moves into the first trajectory path along with the second part of the moving part 230.

[0095] Reference Figure 12 and Figure 13 In one possible embodiment of this application, when the user operates the electronic device from a folded state to an unfolded state, the first moving part 233 gradually moves into the second sliding groove 225, and the second moving part 232 gradually moves out of the first limiting groove 121a; conversely, when the user operates the electronic device from an unfolded state to a folded state, the first moving part 233 gradually moves out of the second sliding groove 225, and the second moving part 232 gradually moves into the first limiting groove 121a.

[0096] Based on this, in the first electronic device provided in the embodiments of this application, the rotating shaft device includes a moving component 230, a trajectory path component, and a limiting component 240. The first body 010 and / or the second body 020 are used to drive the moving component 230 to move, the trajectory path component is used to provide the trajectory path of the moving component 230, and the limiting component 240 is used to limit the movement of the moving component 230 on the trajectory path. The moving component 230 moves on the trajectory path under the driving action of the first body 010 and / or the second body 020, and the movement trajectory of the moving component 230 is matched with the trajectory path based on the limiting component 240. The trajectory path component and the limiting component 240 can be the trajectory path component and the limiting component 240 provided in the embodiments of this application.

[0097] Furthermore, in the second type of electronic device provided in the embodiments of this application, the rotating shaft device includes a moving component 230, a trajectory path component, and a limiting component 240. The first body 010 and / or the second body 020 are used to drive the moving component 230 to move, and the trajectory path component is used to provide a trajectory path for the moving component 230. The limiting component 240 is used to limit the stopping position of the moving component 230 on the trajectory path. The moving component 230 moves on the trajectory path under the driving action of the first body 010 and / or the second body 020, and the stopping position of the moving component 230 on the trajectory path is matched with the trajectory path based on the limiting component 240. The trajectory path component and the limiting component 240 can be the trajectory path component and the limiting component 240 provided in the embodiments of this application.
