Description
Technical Field

[0002] In terms of current electronic device development trends, foldable screen phones, foldable screen computers, and other foldable electronic devices will become the future trend. For foldable electronic devices, the rotating module is crucial, as its performance directly affects the overall functionality and user experience. Typically, due to the lack of damping during rotation, the rotating module only has a locking function in two positions: open and closed. That is, the rotating module can only hover in the unfolded and folded states, and it does not have the hovering function in the intermediate state between the unfolded and folded states. Summary of the Invention
[0003] This disclosure provides a rotating module and an electronic device.
[0004] According to a first aspect of the present disclosure, a rotating module is provided, comprising:
[0005] support;
[0006] The rotating component includes a first rotating component and a second rotating component, which are respectively connected to the bracket;

[0011] In some embodiments, the elastic arm that contacts the first rotating member and the elastic arm that contacts the second rotating member are both oriented toward the center of the bracket.
[0012] In some embodiments, the damping member in contact with the first rotating member and the damping member in contact with the second rotating member are a single-piece structure.
[0013] In some embodiments, both the first rotating member and the second rotating member have a track groove;

[0016] The first rotating member and the second rotating member are deployed together, and the portion of the first end of the damping member embedded in the track groove abuts against the first groove wall of the track groove;
[0017] The first rotating member and the second rotating member are folded together, and the portion of the first end of the damping member embedded in the track groove abuts against the second groove wall of the track groove; the first groove wall and the second groove wall are arranged opposite to each other.
[0018] In some embodiments, both the first rotating member and the second rotating member include:
[0019] The first part protrudes toward the bracket and has a groove, which is arc-shaped, and the outer surface of the groove wall contacts the second end of the damping element;
[0020] The second part, connected to the first part, has a mounting position; the mounting position is used to mount the housing of the electronic device;
[0021] The bracket includes a slide rail with an arc-shaped cross-section. The slide rail is embedded in the slide groove and can move within the slide groove along the direction of the slide groove.
[0022] In some embodiments, the outer surface of the groove wall is an arc surface.
[0023] In some embodiments, both the first surface and the second surface of the first portion have the groove, wherein the second surface is the opposite side of the first surface.
[0024] According to a second aspect of the present disclosure, an electronic device is provided, comprising:
[0025] The rotating module described in any of the above embodiments;
[0026] A first housing is mounted on the first rotating component;
[0027] The second housing is mounted on the second rotating component.
[0028] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:
[0029] As can be seen from the above embodiments, during the relative rotation of the first and second rotating components of this disclosure, an interaction of forces is generated between them and the damping component, which generates a damping force between the rotating component and the damping component that can maintain the state of the rotating component, thereby achieving stable hovering of the first and second rotating components at more positions during the relative rotation.
[0030] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description
[0031] The accompanying drawings, which are incorporated in and form a part of this specification, illustrate embodiments consistent with this disclosure and, together with the description, serve to explain the principles of this disclosure.
[0032] Figure 1 This is one of the structural schematic diagrams of a rotating module according to an exemplary embodiment;
[0033] Figure 2 This is a second schematic diagram of the structure of a rotating module according to an exemplary embodiment;
[0034] Figure 3 This is the third schematic diagram of the structure of a rotating module according to an exemplary embodiment. Detailed Implementation
[0035] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.
[0036] In the description of this disclosure, it should be understood that the terms "center," "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 3 The indicated orientation or positional relationship.
[0037] This disclosure provides a rotating module, including:
[0038] Bracket 130;
[0039] The rotating component includes a first rotating component 110 and a second rotating component 120, which are respectively connected to the bracket 130;
[0040] A damping element 140, wherein a first end 140 of the damping element 140 is fixed to the bracket 130, and a second end of the damping element 140 contacts the rotating element, for providing damping force for the relative rotation of the first rotating element 110 and the second rotating element 120; wherein the second end is the opposite end of the first end 140.
[0041] The bracket 130 is located between the rotating member and the damping member 140.
[0042] like Figure 1 As shown, the bracket 130 supports the rotating component and the damping component 140. Both the first rotating component 110 and the second rotating component 120 are rotatably connected to the bracket 130. The process of the first rotating component 110 and the second rotating component 120 rotating relative to each other is the process of the first rotating component 110 rotating relative to the bracket 130, and / or the second rotating component 120 rotating relative to the bracket 130. When the first rotating component 110 and the second rotating component 120 rotate towards each other relative to the bracket 130, the included angle between them gradually decreases until it is approximately 0°. At this point, the first rotating component 110 and the second rotating component 120 are in a folded state. When the first rotating component 110 and the second rotating component 120 rotate away from each other relative to the bracket 130, the included angle between them gradually increases until it is approximately 180°. At this point, the first rotating component 110 and the second rotating component 120 are in an unfolded state.
[0043] In some embodiments, one of the rotating component and the bracket has a bushing, and the other of the rotating component and the bracket has a shaft core. The shaft core is coaxial with the bushing and is embedded within the bushing. Through the cooperation of the shaft core and the bushing, a rotational connection between the first rotating component and the bracket, and a rotational connection between the second rotating component and the bracket can be achieved. It is understood that the rotational connection method between the rotating component and the bracket is not limited to the connection method of the shaft core and the bushing.
[0044] In this embodiment of the present disclosure, the rotating member is in contact with the damping member, and at least a frictional force is generated between the rotating member and the damping member. At least this frictional force can serve as a damping force to maintain the state of the rotating member.
[0045] In some embodiments, the damping element includes an elastic element having elasticity.
[0046] like Figures 1 to 3 As shown, where, Figure 2The bracket 130 is not shown. During relative rotation, the first rotating member 110 and the second rotating member 120 of this disclosure interact with the damping member 140, causing the damping member 140 to deform. The deformed damping member 140 generates an elastic force as a damping force, which can maintain the state of the rotating member and achieve stable hovering of the first rotating member 110 and the second rotating member 120 in more positions during relative rotation.
[0047] In a specific example, both the first and second rotating components can rotate between 0° and 90°. When both the first and second rotating components rotate at 0°, they are in a folded state; when both rotate at 90°, they are in an unfolded state. The rotating module of this embodiment utilizes the damping force provided by the damping component, allowing the first and second rotating components to remain at any angle between 0° and 90°. For example, the first and / or second rotating components can remain at angles of 30°, 50°, or 60° without any supporting structure.
[0048] In some embodiments, when the first rotating member and the second rotating member are in an unfolded state and a folded state, the damping member is in a compressive deformation state or a tensile deformation state. That is, the interaction between the rotating member and the damping member can be: the rotating member compresses the damping member, or the rotating member stretches the damping member.
[0049] Damping components include, but are not limited to, elastic elements such as springs or spring sheets. Springs can be compression springs or tension springs. Compared to springs, spring sheets occupy less space and are more suitable for use in the limited space within electronic devices.
[0050] In a non-limiting sense, the contact between the second end of the damping element and the rotating element includes: the second end of the damping element abutting against or being fixedly connected to the rotating element. For example, when the damping element is a compression spring or a spring sheet, the rotating element can abut against the damping element. For example, when the damping element is a tension spring, in order to stretch the tension spring during rotation, the second end of the tension spring needs to be fixed to the rotating element.
[0051] In a specific example, the second end of the damping element abuts against the rotating element, and during the rotation of the rotating element relative to the bracket, the second end of the damping element slides in contact with the rotating element. This sliding contact ensures the continuity of the damping force provided by the damping element, and the sliding friction generated during the sliding process further increases the damping force, enhancing the damping feel during the use of the electronic device, further ensuring the hovering effect, and optimizing the user experience.
[0052] In a specific example, such as Figure 1 and Figure 3As shown, the damping element 140 is located within the area of the support 130. That is, the outer surface of the damping element 140 smoothly transitions with the outer surface of the support 130, the damping element 140 is within the orthographic projection range of the support 130, and the damping element 140 does not protrude from the outer surface of the support 130. This structural feature reduces the space occupied by the damping element 140 and improves the overall integrity of the damping element 140 and the support 130.
[0053] There are at least two damping components (140). Figure 2 Two damping elements 140 are shown as an example, which are in contact with the first rotating element 110 and the second rotating element 120, respectively.
[0054] Fixing the first end of the damper to the bracket helps maintain the stability of the damper's position and reduces its movement during the use of the rotating module. Alternatively, the damper can be fixed by welding or by using fasteners such as screws to pass through the damper and the bracket respectively.
[0055] In some embodiments, the rotating module further includes a housing that covers the bracket and the damping element. As the outer surface of the rotating module, the housing not only helps to limit dust and other external environmental elements from entering the interior of the rotating module, but also further confines the damping element between the bracket and the housing, thereby further reinforcing the connection between the damping element and the bracket.
[0056] This embodiment utilizes the elasticity of a damping component to provide damping force, achieving a greater damping force to meet the needs of large-screen electronic devices. Furthermore, different damping forces can be adjusted by changing the magnitude of the elastic force, offering flexibility and convenience. Moreover, using friction as damping force requires the cooperation of multiple parts, increasing the space occupied by the rotating module. In this embodiment, only the damping component and the rotating component are needed, reducing the number of parts in the rotating module and thus minimizing its space requirements.
[0057] In other alternative embodiments, the second end of the damping element 140 has:
[0058] At least one elastic arm 142 protrudes toward the rotating member, and the elastic arm 142 contacts the first rotating member 110 and / or the second rotating member 120.
[0059] Multiple elastic arms 142 help to improve damping force and further meet the needs of large-screen electronic devices for suspension.
[0060] Figure 2An exemplary illustration shows each damping element 140 having two elastic arms 142, spaced apart. It is understood that the number of elastic arms 142 on the damping element 140 in contact with the first rotating element 110 and the damping element 140 in contact with the second rotating element 120 can be the same or different. However, having multiple damping elements 140 with identical elastic arms 142 provides a more uniform damping force, making the damping sensation of the first rotating element 110 during rotation similar to that of the second rotating element 120 during rotation, thus improving the user experience.
[0061] In a specific example, the damping element is a spring, and the magnitude of the damping force can be adjusted by adjusting the degree of bending of the elastic arm. For example, generally speaking, for damping elements of the same material and specifications, the greater the degree of bending of the elastic arm toward the rotating part, the greater the elastic damping force that the elastic arm can provide, and vice versa.
[0062] In other alternative embodiments, the elastic arm 142 that contacts the first rotating member 110 and the elastic arm 142 that contacts the second rotating member 120 are both oriented toward the center of the bracket 130.
[0063] like Figure 2 and Figure 3 As shown, the second end of the damping member 140 is close to the center of the bracket 130, while the first end 140 of the damping member 140 is close to the edge of the bracket 130. By placing the elastic arm 142 close to the center of the bracket 130, the deformation of the elastic arm 142 does not extend beyond the bracket 130, fully utilizing the internal space of the bracket 130, resulting in a more compact structure and reduced rotation module size. Furthermore, in practical use, the portion of the rotating component away from the bracket 130 needs to connect to components such as the electronic device housing. Placing the elastic arm 142 close to the center of the bracket 130 also helps reduce the impact of the electronic device housing on the elastic arm 142.
[0064] In other alternative embodiments, the damping member 140 that contacts the first rotating member 110 and the damping member 140 that contacts the second rotating member 120 are a single-piece structure.
[0065] The one-piece structure increases the strength of the damping components and also facilitates installation. For example... Figure 2 Taking the two damping components shown as an example, this integrated structure allows for contact between the two rotating components and the damping components in a single installation step, eliminating the need for separate installation steps for each damping component. This saves installation steps and improves assembly efficiency.
[0066] It is understandable that multiple damping components can also be independent, separate structures.
[0067] In other alternative embodiments, both the first rotating member 110 and the second rotating member 120 have a track groove 160;
[0068] At least a portion of the first end 140 of the damping member 140 is embedded in the track groove 160 and contacts the rotating member within the track groove 160.
[0069] like Figure 2 As shown, the damping member 140 has a protruding portion 1411 that protrudes towards the track groove 160; the protruding portion 1411 is embedded in the track groove 160 and contacts the rotating member within the track groove 160. The contact between the protruding portion 1411 of the damping member 140 and the track groove 160 on the rotating member helps to increase the friction between the damping member 140 and the rotating member support 130, thereby improving the damping force during the rotation of the rotating member. Moreover, the slotting of the track groove 160 on the rotating member also helps to reduce the weight of the rotating member. Embedding the protruding portion into the track groove 160 further increases the compactness of the assembly between the damping member 140 and the rotating member.
[0070] The track groove 160 guides the sliding of the damping element 140 relative to the rotating element, improving the smoothness and stability of the sliding process. The protrusion 1411, embedded in the track groove 160, further restricts the disengagement of the damping element 140 from the rotating element.
[0071] In other optional embodiments, the trajectory groove 160 includes: a first groove wall 161 and a second groove wall 162; the second groove wall 162 and the first groove wall 161 form the motion trajectory of the trajectory groove 160;
[0072] The first rotating member 110 and the second rotating member 120 are spread out, and the portion of the first end of the damping member 140 embedded in the track groove 160 abuts against the first groove wall 161 of the track groove 160.
[0073] The first rotating member 110 and the second rotating member 120 are folded together, and the first end of the damping member 140 is embedded in the track groove 160 and abuts against the second groove wall 162 of the track groove 160; the first groove wall 161 and the second groove wall 162 are arranged opposite to each other.
[0074] The protrusions, in conjunction with the groove wall of the track, limit the rotation of the rotating parts.
[0075] When folded, the rotation angle of the rotating component is defined as minimum; when unfolded, the rotation angle of the rotating component is defined as maximum. Through the contact between the damping element 140 and the groove wall of the track groove 160, the user will also perceive that the rotating component is in its maximum unfolded state.
[0076] In some embodiments, such as Figure 2 and Figure 3 As shown, when the first rotating member 110 and the second rotating member 120 rotate from the folded state to the unfolded state, the protrusion 1411 moves within the track groove 160. Typically, to accommodate the rotation process, the track groove 160 is approximately arc-shaped. When the protrusion 1411 abuts against the first groove wall 161 of the track groove 160, the protrusion 1411 prevents the rotating member from continuing to rotate, and the rotating member stops due to the limitation imposed by the protrusion 1411. The first groove wall 161 of the track groove 160 can be used to limit the maximum angle that the rotating member can rotate. When the first rotating member 110 and the second rotating member 120 rotate from the unfolded state to the folded state, the second groove wall 162 of the track groove 160 can be used to limit the minimum angle that the rotating member can rotate.
[0077] In other alternative embodiments, both the first rotating member 110 and the second rotating member 120 include:
[0078] The first part 112 protrudes toward the bracket 130 and has a groove 150. The groove 150 is arc-shaped, and the outer surface 151 of the groove wall of the groove 150 contacts the second end of the damping member 140.
[0079] The second part 111, connected to the first part 112, has a mounting position 1111; the mounting position 1111 is used to mount the housing of the electronic device;
[0080] The bracket 130 includes a slide rail 131 with an arc-shaped cross-section. The slide rail 131 is embedded in the slide groove 150 and can move within the slide groove 150 along the direction set by the slide groove 150.
[0081] like Figures 1 to 3 As shown, during the rotation of the rotating component, the slide rail 131 slides within the slide groove 150. Since the slide groove 150 is arc-shaped, the rotation trajectory of the rotating component is also arc-shaped.
[0082] When the first and second rotating components rotate relative to each other, while the slide rail slides within the groove, the second end of the damping component also slides along the groove wall, providing continuous damping force for the rotation process. The damping component not only generates damping force through elastic deformation, but also generates sliding friction during the sliding process of the relative rotating components. This sliding friction also provides damping force for the relative rotation of the first and second rotating components.
[0083] Without limitation, the mounting position includes a mounting hole for fasteners such as screws to pass through, which are used to secure the housing and second part of the electronic device.
[0084] In some embodiments, the track groove is located on the first portion, and the shape of the track groove may be the same as the shape of the slide groove. During the rotation of the rotating member, while the slide rail slides within the slide groove, the protruding portion of the damping member also slides along the track groove.
[0085] In other alternative embodiments, the outer surface 151 of the groove wall of the groove 150 is an arc surface.
[0086] like Figure 2 and Figure 3 As shown, the radius of curvature of the outer surface 151 of the arc-shaped groove wall is equal at each position. During the relative rotation of the first rotating member 110 and the second rotating member 120, the damping force provided by the damping member 140 is equal. This stable damping force is beneficial to improving the user experience.
[0087] In other alternative embodiments, both the first surface and the second surface of the first portion 112 have the groove 150, wherein the second surface is the opposite side of the first surface.
[0088] like Figure 2 As shown, the two opposite surfaces of the first part 112 are connected to the slide rail 130 of the bracket 130 through the slide groove 150, which increases the contact area between the rotating part and the bracket 130 and helps to improve the stability of the rotation process.
[0089] In a specific example, such as Figure 2 As shown, the cross-section of the first part 112 is semi-circular. The first surface and the second surface refer to the two opposite end faces of the first part 112, respectively. The circumferential surface of the first part 112 has a track groove 160, and the surface of the circumferential surface of the first part 112 other than the track groove 160 is in contact with the damping member 140.
[0090] This disclosure provides an electronic device, including:
[0091] The rotating module described in any of the above embodiments;
[0092] A first housing is mounted on the first rotating component;
[0093] The second housing is mounted on the second rotating component.
[0094] In this embodiment of the disclosure, the number of rotating modules can be one or at least two. Multiple rotating modules are arranged side-by-side in the folding regions of the first and second housings.
[0095] Generally, electronic devices refer to devices that can be folded or unfolded, including but not limited to: mobile phones or laptops.
[0096] The relative positional relationship between the first housing and the second housing is the same as the relative positional relationship between the first rotating member and the second rotating member. For example, when the first rotating member and the second rotating member are in the unfolded state, the first housing and the second housing are also in the unfolded state. When the first rotating member and the second rotating member are in the folded state, the first housing and the second housing are also in the folded state.
[0097] In some embodiments, the electronic device further includes: a foldable screen, the back of which covers a first housing, a second housing, and a rotating module, with the foldable screen and a support located on opposite surfaces of the rotating component. When the first and second rotating components rotate relative to each other, they cause the first and second housings to rotate relative to each other, and the foldable screen rotates with the relative rotation of the first and second housings.
[0098] In practical applications, since the damping component can provide a large damping force, for electronic devices, a large screen not only means that the size of the folding screen is large enough, but also that the size of the first shell and the second shell is relatively large. As a result, the weight borne by the first rotating component and the second rotating component is also relatively large. The damping force of the embodiments of this disclosure can provide sufficient damping force to meet the hovering function of large-screen electronic devices.
[0099] In a specific example, such as Figures 1 to 3 As shown, the electronic device is a mobile phone. A left-hand rotating component (also referred to as the second rotating component 120) and a right-hand rotating component (also referred to as the first rotating component 110) are mounted on a bracket 130. The bracket 130 has a semi-circular slide rail 130. The left-hand rotating component has a semi-circular groove 150. The right-hand rotating component also has this groove 150 feature. Therefore, both left and right rotating components can rotate freely on the bracket 130. A spring is placed on the bracket 130 and fixed to it. The spring is made of an elastic material. The spring has an elastic arm 142. The elastic arm 142 contacts the cylindrical surface of the rotating component (i.e., the outer surface 151 of the groove wall 150). When the spring is fixed to the bracket 130, the elastic arm 142 is compressed and undergoes elastic deformation, thereby generating pressure, which in turn generates damping force. This solution is more efficient in production, lower in cost, occupies less space, and is simpler to assemble. It also has a more stable and continuous damping force, can adapt to larger screens, and produces a better user experience.
[0100] The features disclosed in the several product embodiments provided in this disclosure can be combined arbitrarily without conflict to obtain new product embodiments.
[0101] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This disclosure is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this disclosure are indicated by the claims.
[0102] It should be understood that this disclosure is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this disclosure is limited only by the appended claims.
