Description

Technical Field

[0001] This application belongs to the field of mechanical component technology, specifically involving torque modules, shaft assemblies, and electronic components. Background Technology

[0002] In the field of mechanical components, torque modules are commonly used in various structures to achieve hovering, such as door locks and electronic devices. However, current torque modules have poor friction performance, resulting in poor hovering performance, and their structural size is relatively large. Summary of the Invention

[0003] In view of this, the first aspect of this application provides a torque module, comprising:

[0004] Shaft;

[0005] The first blocking element is fixed to the rotating shaft;

[0006] The second blocking element is fixed to the rotating shaft;

[0007] A rotating assembly is sleeved on the rotating shaft and disposed between the first blocking member and the second blocking member. The portion of the rotating assembly sleeved on the rotating shaft has a first mating part on the side near the first blocking member.

[0008] A sliding assembly includes a first sliding member sleeved on the rotating shaft and disposed on the side of the rotating assembly near the first blocking member; the portion of the first sliding member sleeved on the rotating shaft has a second mating portion on the side near the first mating portion; and

[0009] The first elastic element is sleeved on the rotating shaft and located between the rotating assembly and the second blocking element;

[0010] The rotation of the rotating component enables the first mating part and the second mating part to engage with each other, so that the sliding component slides toward or away from the rotating component; when the sliding component slides away from the rotating component, the first elastic element is in a compressed state and the first mating part and the second mating part abut against each other, so that when the rotating component stops rotating, the rotating component remains stationary relative to the sliding component.

[0011] The torque module provided in the first aspect of this application, firstly, allows the first blocking member, rotating component, sliding component, first elastic component, and second blocking member to be assembled on a rotating shaft, providing a basis for subsequent rotation and sliding. Secondly, by providing a first blocking member on one side of the rotating component, the sliding of the rotating component toward the first blocking member is restricted; similarly, by providing a second blocking member on one side of the first elastic component, the sliding of the first elastic component toward the second blocking member is restricted. In other words, providing a first blocking member and a second blocking member at both ends restricts the sliding range of the rotating component, sliding component, and first elastic component, allowing them to slide only between the first blocking member and the second blocking member.

[0012] Then, by providing a first mating part on the rotating assembly, a second mating part on the first sliding member in the sliding assembly, and a first elastic member, the three components work together so that when the rotating assembly rotates, the first and second mating parts cooperate to allow the sliding assembly to slide towards or away from the rotating assembly. This can also be understood as the rotating assembly sliding towards or away from the first sliding member. During this sliding process, the rotating assembly contacts and compresses the first elastic member. The compressed first elastic member then provides a rebound force to the rotating assembly, causing the first mating part to tightly abut against the second mating part, thus ensuring the rotating assembly tightly abuts against the first sliding member. Simultaneously, the rebound force from the first elastic member is converted into pressure exerted by the rotating assembly on the first sliding member. Since the frictional force and pressure between the rotating assembly and the sliding assembly are positively correlated, when the frictional force exceeds a preset value and the rotating assembly stops rotating, the rotating assembly will not rotate relative to the sliding assembly; that is, the sliding assembly and the rotating assembly remain relatively stationary. The preset value can be the weight of the rotating assembly or additional forces such as thrust or pull acting on the rotating assembly. That is, under the action of the rebound force of the first elastic element, the rotating component applies additional pressure to the sliding component, so that the friction between the rotating component and the sliding component is greater than the preset value, and the sliding component will not rotate relative to the rotating component, thereby keeping the rotating component in a stationary state, and enabling the rotating component to achieve functions such as hovering and self-tightening.

[0013] In summary, compared to related technologies that only use a cam to achieve the hovering function, this application, through the interaction of the first mating part, the second mating part, and the first elastic element, can provide greater friction and improve friction performance. This enhances both the hovering and self-tightening effects of the rotating component. In other words, when the same amount of friction is required, the torque module of this application is smaller, improving the compactness of the torque module structure. Furthermore, this application achieves limiting and blocking effects through the blocking elements on both sides, allowing the torque module to achieve the aforementioned movements independently. Therefore, the torque module can independently form a torque module, facilitating assembly.

[0014] A second aspect of this application provides a rotating shaft assembly, including a torque module as described in the first aspect of this application, wherein two torque modules are arranged axially symmetrically, and the rotating component in one of the torque modules extends in a direction away from the rotating component in the other torque module.

[0015] The pivot assembly provided in the second aspect of this application, by using the torque module provided in the first aspect of this application, can provide pressure and thus friction through the first elastic element. Therefore, compared with related technologies, it can not only improve the hovering and self-tightening effect, but also, when the same friction is required to achieve hovering, the pivot assembly of this application can adopt a smaller size, thereby improving the compactness of the pivot assembly structure.

[0016] Furthermore, the use of smaller torque modules reduces the gap between the two torque modules in the shaft assembly. This can also be understood as reducing the bending radius of the shaft assembly by using smaller torque modules, thus resulting in a smaller gap between the two rotating components after bending.

[0017] A third aspect of this application provides an electronic device including two housings, a flexible screen, and a pivot assembly as provided in the second aspect of this application. At least portions of the two housings are respectively disposed on opposite sides of the pivot assembly, and the housings are connected to the rotating component in the pivot assembly. The flexible screen is mounted on one side of the housings and the rotating component.

[0018] The electronic device provided in the third aspect of this application, by using the pivot assembly provided in the second aspect of this application, can provide pressure and thus friction through the first elastic element. Therefore, compared with related technologies, it can not only improve the hovering and self-tightening effects, but also, when the same friction is required to achieve hovering, the pivot assembly of this application can adopt a smaller size. This improves the compactness of the pivot assembly structure, thereby reducing the internal space occupied by the pivot assembly in the electronic device, and also reduces the bending radius of the electronic device, thus making the gap between the two transmission components smaller after bending.

[0041] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0042] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0043] In the field of mechanical components, torque modules are commonly used in various structures to achieve hovering, such as door locks and electronic devices. However, current torque modules have poor friction performance, resulting in poor hovering performance, and their structural size is relatively large. For example, when torque modules are used in U-shaped foldable screen phones, the foldable screen phone usually requires the torque module to provide a frictional force greater than a preset force to achieve hovering. However, because it is necessary to ensure that the provided external force is greater than the preset force to achieve hovering, the size of the components in the torque module is large, such as the cam, shaft, and rotating parts in related technologies, resulting in a large overall structural size of the torque module. More specifically, most current related technologies use specialized torque components that include cam engagement. However, simulations and calculations show that using a cam alone to achieve hovering requires the cam size to meet torque requirements, resulting in a large overall size of the torque module. This leads to the torque module occupying more internal space in the phone and restricting the size of other components in the phone, reducing phone performance. For example, when the size of the phone battery is limited, it can easily lead to a reduction in the phone's energy storage capacity and battery life.

[0044] In view of this, in order to solve the above problems, this application provides a torque module, which please refer to. Figures 1-2 , Figure 1 This is a three-dimensional structural diagram of the torque module in one embodiment of this application. Figure 2 This is one embodiment of the present application. Figure 1 The exploded view in the image.

[0045] This embodiment provides a torque module 1, including a rotating shaft 11, a first blocking member 12, a second blocking member 13, a rotating assembly 14, a sliding assembly 15, and a first elastic member 16. The first blocking member 12 is fixed to the rotating shaft 11. The second blocking member 13 is fixed to the rotating shaft 11. The rotating assembly 14 is sleeved on the rotating shaft 11 and located between the first blocking member 12 and the second blocking member 13. The portion of the rotating assembly 14 sleeved on the rotating shaft 11 has a first mating portion 1411 on the side near the first blocking member 12. The sliding assembly 15 includes a first sliding member 151 sleeved on the rotating shaft 11 and located on the side of the rotating assembly 14 near the first blocking member 12. The portion of the first sliding member 151 sleeved on the rotating shaft 11 has a second mating portion 1511 on the side near the first mating portion 1411. The first elastic member 16 is sleeved on the rotating shaft 11 and located between the rotating assembly 14 and the second blocking member 13. The rotation of the rotating assembly 14 enables the first mating part 1411 and the second mating part 1511 to engage with each other, so that the sliding assembly 15 slides toward or away from the rotating assembly 14. When the sliding assembly 15 slides away from the rotating assembly 14, the first elastic member 16 is in a compressed state and the first mating part 1411 and the second mating part 1511 abut against each other, so that when the rotating assembly 14 stops rotating, the rotating assembly 14 remains stationary relative to the sliding assembly 15.

[0046] Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a particular order.

[0047] The torque module 1 provided in this embodiment achieves a hovering and self-tightening structure through the cooperation of the rotating component 14, the sliding component 15, and the first elastic element 16. It can also be understood that the rotating component 14 can remain relatively stationary with the sliding component 15. Furthermore, the torque module 1 provided in this embodiment can also cooperate with various components to drive other components to achieve hovering and self-tightening. This embodiment is only used to illustrate the application of the torque module 1 in electronic devices. The electronic devices provided in this embodiment include, but are not limited to, mobile terminals such as mobile phones, tablets, laptops, handheld computers, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, pedometers, etc., as well as fixed terminals such as digital TVs and desktop computers. This embodiment does not limit the types of electronic devices. However, this does not mean that the torque module 1 of this embodiment must be applied to electronic devices. In other embodiments, the torque module 1 can also be applied to other fields, such as door locks and vehicles.

[0048] The torque module 1 provided in this embodiment includes a rotating shaft 11. The rotating shaft 11 is typically used to mount other components onto the rotating shaft 11 to assemble multiple components, allowing them to cooperate and providing a basis for subsequent rotation and sliding. A first blocking member 12, a sliding assembly 15, a rotating assembly 14, a first elastic member 16, and a second blocking member 13 are all mounted on the rotating shaft 11, meaning the rotating shaft 11 passes through the first blocking member 12, the sliding assembly 15, the rotating assembly 14, the first elastic member 16, and the second blocking member 13. The material of the rotating shaft 11 includes, but is not limited to, plastic, metal, etc. Furthermore, this embodiment does not limit the shape of the provided rotating shaft 11; it can be any shape, as long as the rotating shaft 11 passes through the first blocking member 12, the sliding assembly 15, the rotating assembly 14, the first elastic member 16, and the second blocking member 13.

[0049] Optionally, the rotating shaft 11 includes a first portion 111 and a second portion 112 connected to the first portion 111. The first portion 111 passes through the first blocking member 12, the sliding assembly 15, the rotating assembly 14, and at least a portion of the first elastic member 16. The second portion 112 passes through at least a portion of the first elastic member 16 and the second blocking member 13. The radial dimensions of the sliding assembly 15 and the rotating assembly 14 are not greater than the radial dimension of the second portion 112. Since the radial dimensions of the sliding assembly 15 and the rotating assembly 14 are not greater than the radial dimension of the second portion 112, and the sliding assembly 15 and the rotating assembly 14 are sleeved on the first portion 111, the radial dimension of the first portion 111 is not greater than the radial dimension of the second portion 112. By setting the radial dimension of the components, the axial movement of the sliding assembly 15 and the rotating assembly 14 relative to the rotating shaft 11 can be restricted. This allows the sliding assembly 15 and the rotating assembly 14 to press the first elastic member 16 when they move away from the first blocking member 12. At the same time, the sliding range of the sliding assembly 15 and the rotating assembly 14 in the axial direction of the rotating shaft 11 is limited, avoiding excessive compression of the first elastic member 16. This improves the stability of the torque module 1 and extends its service life.

[0050] The torque module 1 provided in this embodiment includes a first blocking member 12, which is typically used to restrict the movement of other components. Optionally, the first blocking member 12 may be composed of protrusions on the periphery of the rotating shaft 11, or it may be an independent component mounted on the rotating shaft 11. The first blocking member 12 is sleeved on the rotating shaft 11, which can also be understood as the first blocking member 12 having a through hole through which the rotating shaft 11 passes, thereby connecting the first blocking member 12 to the rotating shaft 11. Optionally, the first blocking member 12 is fixed to the rotating shaft 11 by means including but not limited to fixed connection, snap connection, interference fit, etc. The material of the first blocking member 12 includes but is not limited to plastic, metal, etc., and this embodiment does not limit the first blocking member 12 provided, which can be a component of any shape, as long as the first blocking member 12 can limit the axial sliding of the sliding component 15 relative to the rotating shaft 11. Optionally, the first blocking member 12 may be a gasket.

[0051] The torque module 1 provided in this embodiment includes a second blocking member 13, which is also typically used to restrict the movement of other components. Optionally, the second blocking member 13 may be composed of protrusions on the periphery of the rotating shaft 11, or it may be an independent component mounted on the rotating shaft 11. The second blocking member 13 is fitted onto the rotating shaft 11, which can also be understood as the second blocking member 13 having a through hole through which the rotating shaft 11 passes, thereby connecting the second blocking member 13 to the rotating shaft 11. Optionally, the second blocking member 13 may be fixed to the rotating shaft 11 by means including but not limited to fixed connection, snap-fit ​​connection, interference fit, etc. The material of the second blocking member 13 includes but is not limited to plastic, metal, etc., and this embodiment does not limit the second blocking member 13 provided; it may be a component of any shape, as long as the second blocking member 13 can limit the axial sliding of the first elastic member 16 relative to the rotating shaft 11. Optionally, the second blocking member 13 may be a gasket.

[0052] The first blocking member 12 and the second blocking member 13 are positioned differently relative to the rotating shaft 11, thus restricting different components. In this embodiment, by providing the first blocking member 12 on one side of the rotating member, the sliding assembly 15 is restricted from sliding toward the first blocking member 12. Similarly, by providing the second blocking member 13 on one side of the first elastic member 16, the sliding of the first elastic member 16 toward the second blocking member 13 is restricted. The first blocking member 12 and the second blocking member 13 are respectively located at both ends of the sliding assembly 15, the rotating assembly 14, and the first elastic member 16. Therefore, the first blocking member 12 and the second blocking member 13 can restrict the sliding range of the sliding assembly 15, the rotating assembly 14, and the first elastic member 16, allowing them to slide only between the first blocking member 12 and the second blocking member 13.

[0053] The torque module 1 provided in this embodiment includes a rotating component 14. The rotating component 14 is typically used for rotation and can also be used to cooperate with other components to drive them to rotate synchronously. Furthermore, the rotating component 14 can also cooperate with other components on the rotating shaft 11, such as a sliding component 15, meaning the rotating component 14 can rotate relative to the sliding component 15. The rotating component 14 is provided with a first mating part 1411. It should be noted that in actual production, the rotating component 14 and the first mating part 1411 are integrally formed structural parts, but for ease of understanding, the rotating component 14 and the first mating part 1411 are artificially given different names. The material of the rotating component 14 includes, but is not limited to, plastic, metal, etc., and this embodiment does not limit the provided rotating component 14; it can be a component of any shape, as long as it has a first mating part 1411. Furthermore, this application does not limit the shape of the first mating part 1411, as long as the first mating part 1411 and the second mating part 1511 can cooperate with each other. The first mating part 1411 is provided on the portion of the rotating assembly 14 that houses the rotating shaft 11. Specifically, the first mating part 1411 is positioned corresponding to the outer periphery of the rotating shaft 11, allowing the rotating assembly 14 to engage with other components when rotated to any angle. Alternatively, the first mating part 1411 can be understood as having a through hole through which the rotating shaft 11 passes. The structure of the first mating part 1411 will be described in detail below.

[0054] The torque module 1 provided in this embodiment also includes a sliding component 15, which is a component that can slide axially relative to the rotating shaft 11. The sliding component 15 includes a first sliding member 151, which is sleeved on the rotating shaft 11 and can slide axially relative to the rotating shaft 11. The first sliding member 151 is provided with a second mating part 1511. It should be noted that in actual production, the first sliding member 151 and the second mating part 1511 are integrally formed structural components, but for ease of understanding, the first sliding member 151 and the second mating part 1511 are artificially given different names. The material of the first sliding member 151 includes, but is not limited to, plastic, metal, etc., and this embodiment does not limit the first sliding member 151 provided; it can be a component of any shape, as long as it is provided with a second mating part 1511. Furthermore, this application does not limit the shape of the second mating part 1511, as long as the first mating part 1411 and the second mating part 1511 can cooperate with each other. The second mating part 1511 is provided on the portion of the first sliding member 151 that sleeves the rotating shaft 11, so that the second mating part 1511 can also slide relative to the rotating shaft 11. It can also be understood that the second mating part 1511 has a through hole through which the rotating shaft 11 passes. The structure of the second mating part 1511, and the specific mating method between the first mating part 1411 and the second mating part 1511, will be described in detail below.

[0055] Furthermore, when the rotating component 14 rotates relative to the sliding component 15, either the sliding component 15 or the rotating component 14 slides relative to the rotating shaft 11. Optionally, in one embodiment, when the rotating component 14 rotates, it rotates relative to the rotating shaft 11 in the circumferential direction, meaning that when the rotating component 14 rotates, the rotating shaft 11 is stationary. At this time, the sliding component 15 is stationary relative to the rotating shaft 11 in the circumferential direction and only slides relative to it in the axial direction. That is, the sliding component 15 cannot rotate relative to the rotating shaft 11, but can only slide relative to it, and the rotating component 14 can also slide relative to it in the axial direction. The specific cooperation process between the rotating component 14 and the sliding component 15 will be described in detail below.

[0056] The torque module 1 provided in this embodiment further includes a first elastic element 16, which is disposed between the rotating component 14 and the second blocking component 13. Optionally, the first elastic element 16 may contact the rotating component 14 and the second blocking component 13, or it may not contact them. It is sufficient that when the rotating component 14 slides relative to the rotating shaft 11, the first elastic element 16 can connect with the rotating component 14 and the second blocking component 13 and be in a compressed state. More preferably, the connection method between the first elastic element 16 and the rotating component 14 and the second blocking component 13 includes, but is not limited to, abutment, fixed connection, detachable connection, adhesive bonding, etc. The first elastic element 16 can be a helical spring, a spiral spring, a leaf spring, a disc spring, etc.

[0057] In addition, the first blocking member 12, the sliding component 15, the rotating component 14, the first elastic member 16, and the second blocking member 13 can all be fitted onto the rotating shaft 11 to achieve assembly and provide a basis for subsequent rotation and sliding. It can also be understood that the first blocking member 12, the sliding component 15, the rotating component 14, the first elastic member 16, and the second blocking member 13 are all provided with corresponding through holes, and the rotating shaft 11 passes through the corresponding through holes.

[0058] As can be seen from the above, when the first mating part 1411 and the second mating part 1511 cooperate with each other, the rotation of the rotating component 14 relative to the sliding component 15 can be converted into the sliding of the rotating component 14 relative to the rotating shaft 11. When the sliding component 15 slides away from the rotating component 14 relative to the rotating shaft 11, that is, when the rotating component 14 slides towards or away from the sliding component 15, the sliding range of the first elastic member 16 is limited by the second blocking member 13 at the other end of the first elastic member 16. This allows the first elastic member 16 to be connected to the rotating component 14 and the second blocking member 13, and the rotating component 14 compresses the first elastic member 16, so that the first elastic member 16 is in a compressed state.

[0059] It should be further explained that when the rotating component 14 slides toward or away from the sliding component 15, the first elastic element 16 can be in a compressed state. However, when the rotating component 14 has not yet rotated relative to the sliding component 15, that is, when the first elastic element 16 is in its initial state, this embodiment does not limit the initial state of the first elastic element 16. The initial state of the first elastic element 16 includes, but is not limited to, a stretched state, a balanced state, or a compressed state.

[0060] In another embodiment, the first elastic element 16 is in a pre-compressed state. When the first mating part 1411 and the second mating part 1511 are not mated, that is, when the rotating component 14 is not sliding towards or away from the sliding component 15, the first elastic element 16 is already in a compressed state. The first elastic element 16 in the pre-compressed state can compensate for the axial movement of the first elastic element 16 relative to the rotating shaft 11. It can also be understood that after the torque module 1 has been used for a period of time, even if the size of the first elastic element 16 changes or the structure becomes loose, the first elastic element 16 in the pre-compressed state can still compensate for the axial movement of the first elastic element 16 relative to the rotating shaft 11, thereby improving the stability of the torque module 1 and ensuring the long-term consistency of the torque feel in the torque module 1.

[0061] like Figure 1 As shown, by providing a first mating part 1411 on the rotating assembly 14, a second mating part 1511 on the first sliding member 151 of the sliding assembly 15, and a first elastic member 16, through the cooperation of the three, when the rotating assembly 14 is relative to the sliding assembly 15 (as shown), the first mating part 1411 is provided on the rotating assembly 14, the second mating part 1511 is provided on the first sliding member 151, and the first elastic member 16 is provided on the sliding member 15, the first mating part 1411 is provided on the first sliding member 151, and the first elastic member 16 is provided on the sliding member 15. Figure 1 When the sliding assembly 15 rotates (as shown in the D2 direction), the first mating part 1411 and the second mating part 1511 cooperate to make the sliding assembly 15 move towards or away from the rotating assembly 14 (as shown in the D2 direction). Figure 1 (As shown in the direction of D1) Sliding, even if the rotating component 14 slides towards or away from the first sliding member 151. It can also be understood that when the rotating component 14 rotates relative to the sliding component 15, the first mating part 1411 also rotates relative to the second mating part 1511. Since the first mating part 1411 and the second mating part 1511 can cooperate with each other, the rotating component 14 slides towards or away from the sliding component 15.

[0062] Furthermore, when the sliding component 15 slides in a direction D1 toward or away from the rotating component 14, the rotating component 14 will contact and compress the first elastic element 16. Depending on the reference point, the aforementioned "sliding component 15 moving toward or away from the rotating component 14" can be understood as the sliding component 15 being axially stationary relative to the rotating shaft 11, while the rotating component 14 is axially sliding relative to the rotating shaft 11. Alternatively, the sliding component 15 may slide axially relative to the rotating shaft 11, while the rotating component 14 is axially stationary relative to the rotating shaft 11. Both of these scenarios will ultimately result in the rotating component contacting and compressing the first elastic element, but the specific movement process differs. For example, when the sliding component 15 is axially stationary relative to the rotating shaft 11, and the rotating component 14 slides axially relative to the rotating shaft 11, the rotating component 14 moves in a direction toward or away from the first elastic element 16 to compress the first elastic element 16. Alternatively, when the sliding component 15 slides axially relative to the rotating shaft 11 and the rotating component 14 is axially stationary relative to the rotating shaft 11, the sliding component 15 drives the rotating shaft 11 to move towards or away from the rotating component 14, thereby compressing the first elastic element 16.

[0063] At this time, the first elastic member 16, which is in a compressed state, provides a rebound force to the rotating assembly 14, thereby causing the first mating part 1411 to tightly abut against the second mating part 1511, and the rotating assembly 14 to tightly abut against the first sliding member 151. Simultaneously, the rebound force provided by the first elastic member 16 (such as...) Figure 1 As shown in F1, this can be converted into a certain pressure applied by the rotating component 14 to the first sliding component 151. Since the frictional force between the rotating component 14 and the sliding component 15 is positively correlated with the pressure, i.e., the greater the normal pressure, the greater the frictional force. When the frictional force exceeds a preset value and the rotating component 14 stops rotating, the rotating component 14 will not rotate relative to the sliding component 15; the sliding component 15 and the rotating component 14 remain relatively stationary, i.e., the rotating component 14 is in a stationary state. A stationary state means that when the rotating component 14 stops rotating, it will not rotate relative to the sliding component 15 due to its own weight, external forces, etc. Alternatively, it can be understood that under the action of the rebound force of the first elastic element 16, the rotating component 14 applies additional pressure to the sliding component 15, making the frictional force between the rotating component 14 and the sliding component 15 greater than the preset value. The sliding component 15 will not rotate relative to the rotating component 14, thus keeping the rotating component 14 in a stationary state, enabling the rotating component 14 to achieve functions such as hovering and self-tightening. The preset value can be the weight of the rotating component 14, or additional forces such as pushing or pulling forces acting on the rotating component 14. For example, when the extension direction of the rotating component 14 is parallel to the direction of gravity, the preset value can be the weight of the rotating component 14 itself; when the extension direction of the rotating component 14 intersects the direction of gravity, the preset value can be the thrust, tension, or weight of the rotating component 14.

[0064] Furthermore, to make the rotating component 14 continue to rotate, a force greater than a preset force needs to be provided to change the rotating component 14 from a stationary state relative to the sliding component 15 to a rotating state relative to the sliding component 15. When an external force greater than the preset force is provided, the rotating component 14 can continue to rotate, and the rotating component 14 changes from sliding away from the sliding component 15 to sliding closer to the sliding component 15. When the rotating component 14 slides towards the sliding component and the first elastic element 16 is in a compressed state, since the first elastic element 16 is restoring its deformation at this time, the rebound force of the first elastic element 16 decreases, so the pressure provided by the first elastic element 16 decreases, and the friction force of the rotating component 14 on the sliding component 15 decreases. At this time, only a smaller force is needed to make the rotating component 14 rotate, so the rotating component 14 is easier to rotate, and under the action of the rebound force of the first elastic element 16, the rotating component 14 accelerates to slide towards the sliding component 15, preparing for the next hovering of the torque module 1.

[0065] It should be noted that the torque provided by torque module 1 is related to friction. During the rotation of rotating component 14, friction changes as rotating component 14 or sliding component 15 slides relative to rotating shaft 11. In other words, as rotating component 14 or sliding component 15 changes the state of the first elastic element 16, the torque provided by torque module 1 can increase or decrease.

[0066] In summary, compared to related technologies that only use a cam to achieve the hovering function, this embodiment, through the mutual cooperation of the first mating part 1411, the second mating part 1511, and the first elastic member 16, can provide greater frictional force and improve frictional performance. While enabling the rotating assembly 14 to achieve hovering and self-tightening functions, it also improves the hovering and self-tightening effects. In other words, when the same amount of frictional force is required, the torque module 1 of this embodiment is smaller, improving the compactness of the torque module 1 structure.

[0067] Please refer to Figures 3-4 , Figure 3 This is a three-dimensional structural diagram of the torque module in another embodiment of this application. Figure 4 This is another embodiment of the present application. Figure 3 The exploded view is shown in the figure. In one embodiment, the portion of the rotating assembly 14 sleeved on the rotating shaft 11 has a third mating portion 1421 on the side near the second blocking member 13. The sliding assembly 15 further includes a second sliding member 152 sleeved on the rotating shaft 11 and located on the side of the rotating assembly 14 near the second blocking member 13. The portion of the second sliding member 152 sleeved on the rotating shaft 11 has a fourth mating portion 1521 on the side near the third mating portion 1421.

[0068] The rotation of the rotating assembly 14 also enables the third mating part 1421 to engage with the fourth mating part 1521, so that the sliding assembly 15 slides toward or away from the rotating assembly 14; when the sliding assembly 15 slides away from the rotating assembly 14, the first elastic member 16 is in a compressed state and the third mating part 1421 and the fourth mating part 1521 abut against each other so that when the rotating assembly 14 stops rotating, the rotating assembly 14 remains stationary relative to the sliding assembly 15.

[0069] The rotating assembly 14 provided in this embodiment also includes a third mating part 1421. It should be noted that in actual production, the rotating assembly 14, the first mating part 1411, and the third mating part 1421 are integrally formed structural components. However, for ease of understanding, the rotating assembly 14, the first mating part 1411, and the third mating part 1421 have been given different names. This application does not limit the shape of the third mating part 1421, as long as it can mate with the fourth mating part 1521. The third mating part 1421 is provided on the portion of the rotating component that houses the rotating shaft 11, that is, the third mating part 1421 is provided corresponding to the outer periphery of the rotating shaft 11, so that the rotating assembly 14 can mate with other components when rotated to any angle. It can also be understood that the third mating part 1421 has a through hole through which the rotating shaft 11 passes. Furthermore, the third mating part 1421 is provided on the side of the rotating assembly 14 near the second blocking member 13, while the first mating part 1411 is provided on the side of the rotating assembly 14 near the first blocking member 12. Therefore, the first mating part 1411 and the third mating part 1421 are provided on opposite sides of the rotating assembly 14. The structure of the third mating part 1421 will be described in detail below.

[0070] The sliding assembly 15 provided in this embodiment also includes a second sliding member 152. The second sliding member 152 is axially slidable relative to the rotating shaft 11 and is provided with a fourth mating portion 1521. It should be noted that in actual production, the second sliding member 152 and the fourth mating portion 1521 are integrally formed structural parts, but for ease of understanding, the second sliding member 152 and the fourth mating portion 1521 are artificially given different names. The material of the second sliding member 152 includes, but is not limited to, plastic, metal, etc., and this embodiment does not limit the second sliding member 152 provided; it can be a component of any shape, as long as it is provided with the fourth mating portion 1521. Furthermore, this application does not limit the shape of the fourth mating portion 1521, as long as the third mating portion 1421 and the fourth mating portion 1521 can cooperate with each other. The fourth mating portion 1521 is provided on the part of the second sliding member 152 that sleeves the rotating shaft 11, so that the fourth mating portion 1521 can also slide relative to the rotating shaft 11. Alternatively, it can be understood that the fourth mating part 1521 has a through hole through which the rotating shaft 11 passes. The structure of the fourth mating part 1521, and the specific mating method between the third mating part 1421 and the fourth mating part 1521, will be described in detail below.

[0071] like Figure 3 As shown, when the rotating component 14 is relative to the sliding component 15 (e.g. Figure 3 When rotating (as shown in the D2 direction), the first mating part 1411 and the second mating part 1511 cooperate with each other, and the third mating part 1421 and the fourth mating part 1521 cooperate with each other to cause the rotating assembly 14 to move towards or away from the first sliding member 151 (as shown in the D2 direction). Figure 3 (As shown in direction D1) Sliding. It can also be understood that when the rotating component 14 rotates relative to the sliding component 15, the first mating part 1411 also rotates relative to the second mating part 1511, and at the same time the third mating part 1421 also rotates relative to the fourth mating part 1521. Since the first mating part 1411 and the second mating part 1511, and the third mating part 1421 and the fourth mating part 1521 can cooperate with each other, the rotating component 14 slides in a direction closer to or away from the sliding component 15.

[0072] Optionally, in one embodiment, when the first blocking member 12 abuts against the first sliding member 151, the first blocking member 12 can restrict the sliding of the first sliding member 151 in the axial direction of the rotating shaft 11. Therefore, when the rotating assembly 14 rotates, the first mating part 1411 also rotates relative to the second mating part 1511, and at the same time, the third mating part 1421 also rotates relative to the fourth mating part 1521 so that the rotating assembly 14 and the second sliding member 152 move in a direction away from the first sliding member 151, thereby causing the second sliding member 152 to contact and compress the first elastic member 16, converting the rebound force into frictional force to achieve the suspension of the torque module 1.

[0073] Alternatively, in another embodiment, there is a gap between the first blocking member 12 and the first sliding member 151. So when the rotating assembly 14 rotates, the first mating part 1411 also rotates relative to the second mating part 1511, and at the same time, the third mating part 1421 also rotates relative to the fourth mating part 1521 so that the first sliding member 151 slides away from the rotating assembly 14, and the second sliding member 152 also moves away from the rotating assembly 14, so that the second sliding member 152 contacts and compresses the first elastic member 16, converting the rebound force into frictional force to achieve the suspension of the torque module 1.

[0074] Alternatively, in another embodiment, when the rotating assembly 14 rotates, the first mating part 1411 also rotates relative to the second mating part 1511, and the third mating part 1421 also rotates relative to the fourth mating part 1521, causing the first sliding member 151 to slide towards the rotating assembly 14, and the second sliding member 152 to also move towards the rotating assembly 14, while the first elastic member 16 is in a compressed state, the first elastic member 16 is recovering its deformation, and the rebound force of the first elastic member 16 decreases. Therefore, the pressure provided by the first elastic member 16 decreases, and the frictional force between the rotating assembly 14 and the sliding assembly 15 decreases. At this time, only a smaller force is needed to make the rotating assembly 14 rotate, thus making the rotating assembly 14 easier to rotate. Under the action of the rebound force of the first elastic member 16, the rotating assembly 14 accelerates towards the sliding assembly 15, preparing for the next hovering of the torque module 1.

[0075] In summary, when the rotating assembly 14 slides towards or away from the sliding assembly 15, the second sliding member 152 contacts and compresses the first elastic member 16. At this time, the compressed first elastic member 16 provides a rebound force to the second sliding member 152, causing the first mating part 1411 to tightly abut against the second mating part 1511, and the third mating part 1421 to tightly abut against the fourth mating part 1521, thus ensuring that the rotating assembly 14 tightly abuts against the sliding assembly 15. Simultaneously, the rebound force provided by the first elastic member 16 (such as...) Figure 3 As shown in F1, the pressure can be converted into a certain pressure applied by the first sliding member 151 to the rotating component 14 and the second sliding member 152. Under the action of the rebound force of the first elastic member 16, the friction between the rotating component 14 and the sliding component 15 is greater than the preset value, so the sliding component 15 will not rotate relative to the rotating component 14, thereby keeping the rotating component 14 in a stationary state and enabling the rotating component 14 to achieve functions such as hovering and self-tightening.

[0076] In summary, compared to related technologies that only have a first mating part 1411 and a second mating part 1511, this embodiment, by providing the first mating part 1411, the second mating part 1511, the third mating part 1421, the fourth mating part 1521, and the first elastic member 16 in mutual cooperation, can further increase the compression of the first elastic member 16 compared to only having the first mating part 1411 and the second mating part 1511. This further increases the rebound force of the first elastic member 16, thereby providing greater friction and further improving friction performance. While enabling the rotating assembly 14 to achieve functions such as hovering and self-tightening, the hovering and self-tightening effects are further improved. In addition, when the same amount of friction force is required, the size of the torque module 1 in this embodiment is further reduced, further improving the compactness of the torque module 1 structure. Furthermore, this embodiment can achieve the limiting and blocking effect through the blocking members provided on both sides, allowing the torque module 1 to achieve the above-mentioned movement on its own. Therefore, the torque module 1 can independently form a torque module, which is easy to assemble.

[0077] The following describes the specific structures of the first mating part 1411, the second mating part 1511, the third mating part 1421, and the fourth mating part 1521. Please refer to [the relevant documentation]. Figures 5-6 , Figure 5 This is a schematic diagram illustrating the cooperation between the first mating part and the second mating part, and between the third mating part and the fourth mating part in another embodiment of this application. Figure 6 This is a schematic diagram illustrating the cooperation between the first mating part and the second mating part, and between the third mating part and the fourth mating part in another embodiment of this application.

[0078] In this embodiment, the first mating portion 1411 includes a plurality of first protrusions 1411a spaced apart, the second mating portion 1511 includes a plurality of second protrusions 1511a spaced apart, the third mating portion 1421 includes a plurality of third protrusions 1421a spaced apart, and the fourth mating portion 1521 includes a plurality of fourth protrusions 1521a spaced apart. The first protrusions 1411a, the second protrusions 1511a, the third protrusions 1421a, and the fourth protrusions 1521a all have peaks. The peaks of the first protrusions 1411a and the third protrusions 1421a are symmetrically arranged, and the peaks of the second protrusions 1511a and the fourth protrusions 1521a are symmetrically arranged.

[0079] When the sliding component 15 slides away from the rotating component 14, and the crest of the first protrusion 1411a contacts the crest of the second protrusion 1511a, and the crest of the third protrusion 1421a contacts the crest of the fourth protrusion 1521a, the first elastic member 16 is in a compressed state and causes the sliding component 15 to abut against the rotating component 14.

[0080] The crest refers to the highest point of the protrusion. In addition to the crest, the first protrusion 1411a, the second protrusion 1511a, the third protrusion 1421a, and the fourth protrusion 1521a also have troughs and slopes, where the trough refers to the lowest point of the protrusion and the slope refers to the side surface between the crest and the trough.

[0081] It should be noted that, since the crests of the first protrusion 1411a and the third protrusion 1421a are symmetrically arranged, and the crests of the second protrusion 1511a and the fourth protrusion 1521a are symmetrically arranged, when the crests of the first protrusion 1411a and the second protrusion 1511a are opposite each other, the crests of the third protrusion 1421a and the fourth protrusion 1521a are also opposite each other; when the crest of the first protrusion 1411a and the trough of the second protrusion 1511a are opposite each other, the crest of the third protrusion 1421a and the trough of the fourth protrusion 1521a are also opposite each other. This can also be understood as the matching state between the first protrusion 1411a and the second protrusion 1511a being the same as the matching state between the third protrusion 1421a and the fourth protrusion 1521a.

[0082] Optionally, firstly, when the rotating component 14 is not rotating relative to the sliding component 15, the engagement states of the first protrusion 1411a and the second protrusion 1511a, and the engagement states of the third protrusion 1421a and the fourth protrusion 1521a, are both with crests and troughs facing each other. Then, when the rotating component 14 rotates relative to the sliding component 15, the engagement state of the first protrusion 1411a and the second protrusion 1511a is that the crests slide along the inclined surface until the crests face each other, and the engagement state between the third protrusion 1421a and the fourth protrusion 1521a is always the same as the engagement state between the first protrusion 1411a and the second protrusion 1511a.

[0083] When the crests of the first protrusion 1411a and the second protrusion 1511a are opposite each other, and the crests of the third protrusion 1421a and the fourth protrusion 1521a are opposite each other, the distance between the sliding component 15 and the rotating component 14 is the largest. Correspondingly, the compression of the first elastic element 16 is more obvious at this time, which can provide a greater rebound force, thereby further improving the friction performance of the torque module 1 and improving the hovering and self-tightening effect. Next, as the rotating assembly 14 continues to rotate relative to the sliding assembly 15 under the action of an external force, the engagement state of the first protrusion 1411a and the second protrusion 1511a is such that the crest continues to slide along the slope until the crest and trough are opposite each other. The engagement state between the third protrusion 1421a and the fourth protrusion 1521a remains the same as that between the first protrusion 1411a and the second protrusion 1511a. During this process, the distance between the sliding assembly 15 and the rotating assembly 14 gradually decreases. Correspondingly, the compression degree of the first elastic element 16 weakens, and the rebound force provided decreases. Due to the reduced friction, the rotating assembly 14 rotates more easily. Finally, the first protrusion 1411a and the second protrusion 1511a, and the third protrusion 1421a and the fourth protrusion 1521a will repeat the above movements, preparing for the next hovering of the torque module 1.

[0084] This can also be understood as follows: when the crests of the first protrusion 1411a and the second protrusion 1511a are opposite each other, and the crests of the third protrusion 1421a and the fourth protrusion 1521a are opposite each other, the crests of the first protrusion 1411a and the second protrusion 1511a can cause the sliding component 15 to slide relative to the rotating component 14 to compress the first elastic member 16, thereby providing a compression amount; and the crests of the third protrusion 1421a and the fourth protrusion 1521a can also cause the sliding component 15 to slide relative to the rotating component 14 to compress the first elastic member 16, thereby providing a compression amount; therefore, two compression amounts can be provided at this time, increasing the rebound force of the first elastic member 16, thereby increasing the friction between the rotating component 14 and the sliding component 15.

[0085] Since the torque module 1 can hover and self-tighten when the wave crests are opposite each other, the number, position, and size of the protrusions can determine the hovering angle. For example, when there are 6 first protrusions 1411a in the first mating part 1411, and the first protrusions 1411a are evenly spaced, and the third protrusion 1421a is correspondingly set with the first protrusions 1411a, the torque module 1 can hover for every 60° rotation of the rotating component 14 relative to the sliding component 15.

[0086] like Figure 5 and Figure 6As shown, in this embodiment, when the rotating component 14 rotates relative to the sliding component 15, the first protrusion 1411a rotates relative to the second protrusion 1511a, and the third protrusion 1421a rotates relative to the fourth protrusion 1521a. At this time, the sliding component 15 slides towards or away from the rotating component 14. Since the engagement state between the first protrusion 1411a and the second protrusion 1511a is the same as the engagement state between the third protrusion 1421a and the fourth protrusion 1521a, the first engagement state of the first engagement part 1411 and the second engagement part 1511, and the third engagement part 1421 and the fourth engagement part 1521 is as follows: Figure 5 As shown, the first state is when the crest of the second protrusion 1511a faces the direction close to the crest of the first protrusion 1411a, and the crest of the fourth protrusion 1521a faces the direction close to the crest of the third protrusion 1421a (e.g. Figure 5 When the sliding component 15 rotates (as shown in the D3 direction), it moves away from the rotating component 14 (e.g., as shown in the D3 direction). Figure 5 (As shown in direction D4) Sliding; the second state is when the crest of the second protrusion 1511a is oriented towards the trough of the first protrusion 1411a, and the crest of the fourth protrusion 1521a is oriented towards the trough of the third protrusion 1421a (as shown in direction D4); Figure 6 When the sliding component 15 rotates (as shown in the D5 direction), it moves towards the direction closer to the rotating component 14 (e.g., as shown in the D5 direction). Figure 6 Slide in the direction shown in D6.

[0087] Secondly, when the sliding component 15 slides away from the rotating component 14, and the crest of the first protrusion 1411a contacts the crest of the second protrusion 1511a, the second sliding member 152 abuts against the first elastic member 16, converting the rebound force into frictional force, thereby enabling the rotating component 14 to achieve functions such as hovering and self-tightening. Therefore, compared to only setting the first protrusion 1411a and the second protrusion 1511a, this embodiment can achieve the hovering function by setting the first protrusion 1411a, the second protrusion 1511a, the third protrusion 1421a, the fourth protrusion 1521a and the first elastic member 16 in combination, thereby making the size of the torque module 1 smaller and further improving the compactness of the torque module 1 structure.

[0088] Please refer to Figure 7 , Figure 7This is a three-dimensional structural diagram of the torque module according to another embodiment of this application. In one embodiment, the rotating assembly 14 includes a first rotating member 141, a second rotating member 142, a connecting member 143, and a bracket 144. The first rotating member 141 is sleeved on the rotating shaft 11 and located near the first sliding member 151, and the first rotating member 141 has a first mating portion 1411 on the side near the first sliding member 151. The second rotating member 142 is sleeved on the rotating shaft 11 and located near the second sliding member 152, and the second rotating member 142 has the third mating portion 1421 on the side near the second sliding member 152. The connecting member 143 is connected at one end to the first rotating member 141 and at the other end to the second rotating member 142. The bracket 144 is sleeved on the rotating shaft 11 and located between the first rotating member 141 and the second rotating member 142.

[0089] The torque module 1 provided in this embodiment includes a first rotating component 141 and a second rotating component 142. The first rotating component 141 and the second rotating component 142 are rotatable and can also be connected to other components to drive those connected components to rotate. This embodiment does not limit the shape or material of the first rotating component 141 and the second rotating component 142. A first mating part 1411 is located on the side of the first rotating component 141 opposite to the second rotating component 142, and a third mating part 1421 is located on the side of the second rotating component 142 opposite to the first rotating component 141. It should be noted that in actual production, the first rotating component 141 and the first mating part 1411 are integrally formed structural components; the second rotating component 142 and the third mating part 1421 are also integrally formed structural components. However, for ease of understanding, the first rotating component 141, the first mating part 1411, the second rotating component 142, and the third mating part 1421 are artificially given different names.

[0090] The torque module 1 provided in this embodiment includes a connector 143, which is used to connect different components. This embodiment does not limit the shape or material of the connector 143. The connection method of the connector 143 includes, but is not limited to, fixed connection, snap-fit ​​connection, and interference fit. Since one end of the connector 143 is connected to the first rotating component 141 and the other end is connected to the second rotating component 142, when either the first rotating component 141 or the second rotating component 142 rotates relative to the sliding assembly 15, the connector 143 can drive either the first rotating component 141 or the second rotating component 142 to rotate synchronously. The first rotating component 141 and the second rotating component 142 have the same rotation angle. Optionally, the connector 143 can be a pin.

[0091] The torque module 1 provided in this embodiment includes a bracket 144, which is used to fix and support other components. This application does not limit the shape or material of the bracket 144. The bracket 144 is sleeved on the rotating shaft 11, and the bracket 144 can slide axially relative to the rotating shaft 11, while the bracket 144 is circumferentially stationary relative to the rotating shaft 11. Optionally, the bracket 144 is provided with an installation space, which can be used to connect with other components, improving the connection performance of the torque module 1 with other components and broadening the application range of the torque module 1. Further, the installation space may include, but is not limited to, mounting holes, mounting grooves, etc.

[0092] like Figure 7 As shown, when the first rotating member 141 is relative to the sliding assembly 15 (e.g., Figure 7 When rotating in the direction shown in D2, the connecting member 143 drives the second rotating member 142 to rotate synchronously, so that the first mating part 1411 rotates relative to the second mating part 1511, and the third mating part 1421 rotates simultaneously relative to the fourth mating part 1521, so that the sliding assembly 15 moves towards or away from the rotating assembly 14 (e.g., ...). Figure 7 The movement (as shown in D1) is such that the first slider 151 moves toward or away from the first rotating member 141, and the second slider 152 moves toward or away from the second rotating member 142, so that the second slider 152 compresses the first elastic member 16, and the rebound force (such as...) Figure 7 The force (as shown in F1) is converted into friction, causing the first rotating member 141 and the second rotating member 142 to remain stationary relative to the sliding assembly 15, thus achieving hovering. This embodiment improves hovering and self-tightening effects by providing the first rotating member, the second rotating member 142, the connecting member 143, and the bracket 144, allowing these components to cooperate with the sliding assembly 15 and the first elastic member 16.

[0093] It should be noted that during the axial sliding of the rotating component 14 relative to the rotating shaft 11, the bracket 144 is always located between the first rotating component 141 and the second rotating component 142, and slides towards or away from the sliding component 15 simultaneously with the first rotating component 141 and the second rotating component 142.

[0094] Optionally, when the first rotating member 141 rotates, the first mating part 1411 engages with the second mating part 1511, causing the first sliding member 151 to move towards or away from the first rotating member 141. However, since the bracket 144 is located on the side of the first rotating member 141 away from the first sliding member 151, the bracket 144 can restrict the axial sliding of the first rotating member 141 relative to the rotating shaft 11, making the first rotating member 141 axially stationary relative to the rotating shaft 11, i.e., the first rotating member 141 cannot slide relative to the rotating shaft 11.

[0095] Optionally, such as Figure 7 As shown, the first rotating member 141 or the second rotating member 142 in the rotating assembly 14 has a friction surface 145 at the contact point with the bracket 144, satisfying at least one of the two conditions. This embodiment is only illustrated by showing that the friction surface 145 is provided at the contact point between the first rotating member 141 and the bracket 144, and does not mean that the friction surface 145 can only be provided at the contact point between the first rotating member 141 and the bracket 144. When the first rotating member 141 rotates and contacts the bracket 144, the first rotating member 141 rotates relative to the bracket 144, so the first rotating member 141 and the bracket 144 rub against each other on the friction surface 145, thereby generating circumferential friction. By adding the friction surface 145, the friction in the torque module 1 can be further increased, and the hovering effect can be further improved.

[0096] Please refer to Figure 8 , Figure 8 This is a three-dimensional structural diagram of the torque module according to another embodiment of this application. In one embodiment, the first rotating member 141 and the second rotating member 142 are respectively sleeved on both ends of the connecting member 143. The torque module 1 also includes two limiting members 146. One end of the connecting member 143 is connected to one of the limiting members 146, and the other end is connected to the other limiting member 146. One limiting member 146 is fixed to the end of the first rotating member 141 opposite to the second rotating member 142, and the other limiting member 146 is fixed to the end of the second rotating member 142 opposite to the first rotating member 141.

[0097] The torque module 1 in this embodiment includes a limiting member 146, which is used to connect other components to restrict their positions. This embodiment does not limit the shape or material of the limiting member 146. The limiting member 146 connects to a first rotating component 141 or a second rotating component 142, and the connection method includes, but is not limited to, fixed connection, snap-fit ​​connection, and hinge connection. This embodiment only illustrates a snap-fit ​​connection. Optionally, the limiting member 146 has a first snap-fit ​​portion near the rotating component 14, and the rotating component 14 has a corresponding second snap-fit ​​portion on the side near the first snap-fit ​​portion, with at least a portion of the first snap-fit ​​portion located within the second snap-fit ​​portion. When the first snap-fit ​​portion is a protrusion, the second snap-fit ​​portion is a groove; when the first snap-fit ​​portion is a groove, the second snap-fit ​​portion is a protrusion.

[0098] like Figure 8As shown, the first rotating component 141 and the second rotating component 142 are respectively sleeved on both ends of the connecting component 143. This can also be understood as the connecting component 143 passing through both the first rotating component 141 and the second rotating component 142, with the opposite ends of the connecting component 143 connected to limiting components 146. Since the limiting components 146 connect the connecting component 143 and the rotating assembly 14, the connecting component 143 is stably positioned within the torque module 1, preventing it from falling off when the first rotating component 141 and the second rotating component 142 move. This ensures that the connecting component 143 connects the first rotating component 141 and the second rotating component 142, improving the stability of the torque module 1's operation. Furthermore, when the limiting component 146 and the rotating assembly 14 are connected in a detachable manner, the first rotating component 141 and the second rotating component 142 can be avoided during the disassembly of the torque module 1, improving the component recovery rate.

[0099] Please refer to Figure 9 , Figure 9 This is a three-dimensional structural diagram of the torque module in another embodiment of this application. In one embodiment, the torque module 1 further includes a friction element 17, which is fixed to the rotating shaft 11 and located on the side of the second blocking member 13 away from the rotating assembly 14. The rotation of the rotating assembly 14 enables the friction element 17 to rotate relative to the second blocking member 13.

[0100] Friction element 17 is typically used to provide friction. Furthermore, the material of friction element 17 includes, but is not limited to, plastic, metal, etc., and this embodiment does not limit the friction element 17 provided; it can be a component of any shape, as long as it can provide the friction force of an elastic element. Friction element 17 is sleeved on rotating shaft 11, that is, friction element 17 has a through hole through which rotating shaft 11 passes.

[0101] like Figure 9 As shown, when the rotating assembly 14 rotates, the friction element 17 rotates relative to the second blocking element 13, and the friction element 17 and the second blocking element 13 rub against each other, thereby generating circumferential friction. When one end of the first elastic element 16 applies a rebound force to the sliding assembly 15, the other end of the first elastic element 16 also applies a rebound force to the second blocking element 13, thereby causing the second blocking element 13 to apply pressure to the friction element 17. As the degree of compression of the first elastic element 16 increases, the pressure continuously increases, and therefore the circumferential friction also continuously increases, which can further improve the hovering and self-tightening effect of the torque module 1, and further reduce the size of the torque module 1 in this embodiment, thereby further improving the compactness of the torque module 1 structure.

[0102] Please refer to Figure 10 , Figure 10This is a three-dimensional structural diagram of a rotating shaft assembly according to one embodiment of this application. This application also provides a rotating shaft assembly 2, including a torque module 1 as provided in this application, with two torque modules 1 arranged axially symmetrically, and the rotating component 14 in one of the torque modules 1 extending in a direction away from the rotating component 14 in the other torque module 1.

[0103] The rotating shaft assembly 2 of this embodiment includes two torque modules 1, which have been described in detail above and will not be repeated here. The two torque modules 1 are arranged axially symmetrically, or symmetrically along the axial direction of the rotating shaft 11. Due to the axially symmetrical arrangement, the two rotating shafts 11 are arranged adjacent to each other, which reduces the size of the rotating shaft assembly 2. The rotating shaft assembly 2 allows the two rotating components 14 to rotate relative to each other, or to move the two rotating components 14 in directions that bring them closer to or further away from each other.

[0104] Furthermore, one of the rotating components 14 in the rotating shaft assembly 2 extends away from the other rotating component 14, so that when the two rotating components 14 rotate synchronously, they move simultaneously in a direction away from each other or towards each other, so that even if the two rotating components 14 rotate in opposite directions or towards each other, the two rotating components 14 are prevented from rotating in the same direction.

[0105] like Figure 10 As shown, the pivot assembly 2 provided in this embodiment, by using the torque module 1 provided in this application, can provide pressure and thus friction through the first elastic element 16. Therefore, compared with related technologies, it not only improves the hovering and self-tightening effects, but also allows for a smaller size of the pivot assembly 2 when the same friction is required to achieve hovering, thus improving the compactness of the pivot assembly 2 structure. Furthermore, due to the use of a smaller torque module 1, the gap between the two torque modules 1 in the pivot assembly 2 is smaller. It can also be understood that by using a smaller torque module 1, the bending radius of the pivot assembly 2 can be reduced, thereby making the gap between the two rotating components 14 smaller after bending.

[0106] Furthermore, in practical applications, teardrop-shaped hinge shaft assemblies 2 are typically used, and these assemblies are directly and securely connected to other components. If any component fails, the entire hinge may become unusable, and the shaft assembly 2 itself may also be rendered unusable, hindering assembly and repair. This embodiment utilizes a shaft assembly 2 composed of a torque module 1 provided in this application. Through the cooperation of the first blocking member 12, the rotating component 14, the sliding component 15, the first elastic member 16, and the second blocking member 13, the shaft assembly 2 can rotate independently or drive other components connected to the rotating component 14 to rotate synchronously, eliminating the need for cooperation with other components, such as hinges or connections, to achieve hovering. Therefore, this embodiment, by employing the torque module 1 provided in this application, allows the first blocking member 12, the rotating component 14, the sliding component 15, the first elastic member 16, and the second blocking member 13 to be fitted onto the shaft 11, enabling hovering. This avoids the use of hinges in related technologies, simplifies the structure of the shaft assembly 2, makes it more compact, easier to assemble and disassemble, and reduces production costs.

[0107] Please refer to Figures 11-12 , Figure 11 This is a three-dimensional structural diagram of the rotating shaft assembly in another embodiment of this application. Figure 12 This is another embodiment of the present application. Figure 11 The exploded view is shown in the figure. In this embodiment, the sliding assembly 15 further includes a second sliding member 152, which is sleeved on the rotating shaft 11 and located on the side of the rotating assembly 14 near the second blocking member 13. The second sliding members 152 in the two torque modules 1 are interconnected, and the second blocking members 13 in the two torque modules 1 are interconnected. The rotating shaft assembly 2 further includes a second elastic member 18, which is located between the connection point of the two second sliding members 152 and the connection point of the two second blocking members 13.

[0108] The two second sliding members 152 and the two second blocking members 13 are interconnected. The second sliding members 152 and the second blocking members 13 have been described in detail above and will not be repeated here. Optionally, this application does not limit the connection method of the two second sliding members 152 and the two second blocking members 13, and the connection method includes, but is not limited to, fixed connection, snap-fit ​​connection, etc. More optionally, in this embodiment, the connection method of the two second sliding members 152 and the two second blocking members 13 is a fixed connection; the two second sliding members 152 and the two second blocking members 13 can also be integrally formed.

[0109] Optionally, the second elastic element 18 has a pre-compressed state. The pre-compressed state has been described in detail above and will not be repeated here.

[0110] Optionally, the second elastic member 18 is disposed at the connection between the two second sliding members 152 and the connection between the two second blocking members 13 by means including but not limited to adding components, bonding, etc.

[0111] Optionally, the torque module 1 further includes a positioning member 181, which is located between the second sliding member 152 and the second blocking member 13, and is connected to the connection point of the two sliding members or the connection point of the two second blocking members 13; a second elastic member 18 is fitted onto the positioning member 181, and the opposite ends of the second elastic member 18 are in contact with the connection points of the two second sliding members 152 and the connection points of the two second blocking members 13, respectively. This embodiment is only illustrated by setting the positioning member 181.

[0112] like Figure 11 As shown, when the sliding component 15 slides toward or away from the rotating component 14, the second elastic element 18 and the first elastic element 16 deform simultaneously. It can also be understood that when the first mating part 1411 and the second mating part 1511 engage with each other, the first elastic element 16 and the second elastic element 18 can be simultaneously in a compressed state, thereby increasing the pressure exerted by the elastic elements on the rotating component 14 and the sliding component 15, thus increasing the friction between the rotating component 14 and the sliding component 15. This allows for a further reduction in the size of the rotating shaft assembly 2 in this embodiment, thereby further improving the compactness of the rotating shaft assembly 2 structure.

[0113] Optionally, such as Figure 11 As shown, the first sliding members 151 in the two torque modules 1 are interconnected, and the first blocking members 12 in the two torque modules 1 are interconnected. The connection methods include, but are not limited to, fixed connection, snap-fit ​​connection, etc. More optionally, in this embodiment, the connection method of the two first sliding members 151 and the two first blocking members 12 is a fixed connection; the two first sliding members 151 and the two first blocking members 12 can also be integrally formed.

[0114] Optionally, the sliding component 15 can slide axially relative to the rotating shaft 11, but remain stationary circumferentially relative to the rotating shaft 11. That is, the sliding component 15 cannot rotate relative to the rotating shaft 11, but can slide relative to the rotating shaft 11.

[0115] Optionally, such as Figure 11 As shown, the brackets 144 in the two rotating assemblies 14 are interconnected. The connection methods include, but are not limited to, fixed connection, snap-fit ​​connection, etc. More preferably, in this embodiment, the two brackets 144 are connected by a fixed connection; the two brackets 144 can also be formed integrally.

[0116] Please refer to this again. Figure 11 and Figure 12In this embodiment, the rotating assembly 14 is sleeved on the periphery of the rotating shaft 11 and is also provided with a transmission part 19. The rotating assembly also includes a synchronization assembly 191. One end of the synchronization assembly 191 is rotatably connected to one of the transmission parts 19, and the other end is rotatably connected to another transmission part 19, so that the two torque modules 1 move synchronously.

[0117] The transmission part 19 is used to connect other components to realize the transmission between the components. This embodiment does not limit the shape of the transmission part, as long as it can be used for transmission. Optionally, the transmission part 19 includes multiple teeth disposed on the portion of the rotating assembly 14 that is sleeved on the periphery of the rotating shaft 11. Further optionally, the transmission part 19 of one torque module 1 is rotatably connected to the transmission part 19 of another torque module 1 to make the two torque modules 1 move synchronously. It should be noted that the rotatable connection of the transmission part 19 can be a direct rotatable connection or an indirect rotatable connection through cooperation with other components, such as the synchronization assembly 191. In actual production, the transmission part 19 and the rotating assembly 14 can be integrally formed structural components, but for ease of understanding, the transmission part 19 and the rotating assembly 14 are named separately.

[0118] The synchronization component 191 includes, but is not limited to, belts, gear assemblies, etc. Synchronous movement of the two torque modules 1 refers to the synchronous rotation of the two rotating components 14 in opposite directions. It should be noted that, to ensure synchronous rotation of the two rotating components 14 in opposite directions, if the synchronization component 191 is a gear assembly, the number of gears in the gear assembly must be even. Further optionally, the synchronization component 191 in this embodiment includes a first sub-gear and a second sub-gear, which are rotatably connected. The first sub-gear is rotatably connected to one of the transmission parts 19, and the second sub-gear is rotatably connected to the other transmission part 19.

[0119] like Figure 11 As shown, the transmission part 19 rotates synchronously with the rotating component 14. When one rotating component 14 rotates toward or away from another rotating component 14, the transmission part 19 in that rotating component 14 rotates in the same direction. The synchronizing component 191 rotatably connects the two transmission parts 19, so the transmission part 19 drives the other transmission part 19 to rotate in the opposite direction through the synchronizing component 191, thereby causing the other rotating component 14 to rotate in the opposite direction, so as to realize the synchronous movement of the two rotating components 14, that is, the two rotating components 14 rotate synchronously towards or away from each other, so as to improve the synchronization performance between the two torque modules 1 and improve the stability of the rotation of the shaft assembly 2.

[0120] Please refer to this again. Figures 11-12In this embodiment, the rotating assembly 14 further includes a bracket 144, which is sleeved on the rotating shaft 11 and located on the side of the transmission part 19 away from the sliding assembly 15. The rotating shaft assembly 2 further includes a synchronous shaft 192 and a wear-resistant part 193. The synchronous shaft 192 passes through the synchronous assembly 191 and is connected to the bracket 144. The wear-resistant part 193 is fixed to the side of the synchronous assembly 191 away from the bracket 144.

[0121] The rotating shaft assembly 2 provided in this embodiment also includes a wear-resistant component 193. The wear-resistant component 193 has wear resistance and can be used to prevent the two components from rubbing against each other, or to bear the frictional force between the relative movements of the two components, so as to protect the components. Furthermore, since the wear-resistant component 193 is fixed to one side of the synchronization assembly 191, the wear-resistant component 193 can also be used to limit the axial movement of the synchronization assembly 191 relative to the synchronization shaft 192. This application does not limit the shape or quantity of the wear-resistant component 193. Optionally, the fixing method of the wear-resistant component 193 to the side of the synchronization assembly 191 opposite to the bracket 144 includes, but is not limited to, bonding, snap-fit ​​connection, and fixed connection. Further optionally, the synchronization shaft 192 has a receiving groove on the periphery of the synchronization assembly 191 opposite to the bracket 144, and at least a portion of the wear-resistant component 193 is disposed in the receiving groove.

[0122] In summary, the wear-resistant component 193 of this embodiment can not only prevent the synchronization component from rubbing against other components in the shaft assembly 2, such as the sliding component 15, and prevent the synchronization component 191 from jamming, but also restrict the axial sliding of the synchronization component 191 relative to the synchronization shaft 192, thereby further improving the stability of the shaft assembly 2 and increasing its service life.

[0123] Please refer to this as well. Figures 13-14 , Figure 13 This is a three-dimensional structural diagram of the rotating shaft assembly in another embodiment of this application. Figure 14 for Figure 13 A partial enlarged view. In this embodiment, the rotating shaft assembly 2 further includes a third blocking member 194, which is disposed on the side of the wear-resistant member 193 opposite to the synchronization assembly 191.

[0124] The third blocking member 194 is used to block or isolate the components from contacting each other. This embodiment does not limit the shape of the third blocking member. Optionally, the third blocking member 194 can be a protruding portion of another component, or it can be a separate component. Figure 14 As shown, the third blocking member 194 is located on the side of the wear-resistant member 193 away from the synchronization component 191, which can further prevent the synchronization component 191 from jamming due to the friction between the wear-resistant member 194 and other components, such as the sliding component 15, thereby further improving the stability of the movement of the rotating shaft assembly 2.

[0125] Optionally, in this embodiment, the sliding component 15, the rotating component 14, the first elastic element 16, and the second elastic element 18 may be in clearance fit.

[0126] Optionally, in this embodiment, the rotation centers of the first elastic member 16, the mating portion in the rotating assembly 14, the connecting member 143, the mating portion in the sliding assembly 15, and the friction member 17 coincide in the axial direction of the rotating shaft 11. This can also be understood as the motion centers of these components coinciding to improve the stability of the rotating shaft assembly 2 during operation. Furthermore, the connecting member 143 and the synchronization assembly 191 have a gap in their rotation centers, and the connecting member 143 and the synchronization assembly 191 rotate around their respective rotation centers, i.e., their motion centers. Here, the rotation center refers to the center of a circle in which a rotatable component performs circular motion.

[0127] Optionally, in this embodiment, the rotating shaft assembly 2 can achieve synchronous rotation by cooperating with the synchronizing assembly 191 through the connecting member 143. For example, when the first rotating member 141 in a rotating assembly 14 is rotated, the second rotating member 142 in the same rotating assembly 14 is rotated synchronously through the connecting member 143. Then, through the cooperation of two gears 19 with the synchronizing assembly 191, the torque module 1 on the other side can be rotated synchronously in opposite directions. Furthermore, in this embodiment, the rotating shaft assembly 2 can also achieve suspension by cooperating with multiple mating parts, the first elastic member 16, the second elastic member 18, and the friction surface 145 at the contact point between the rotating assembly 14 and the bracket 144.

[0128] Optionally, the rotating shaft assembly 2 of this embodiment can be installed either upright or in reverse to accommodate different components and achieve different spatial structure configurations. Regardless of whether it is installed upright or in reverse, the rotating shaft assembly 2 provides the same torque.

[0129] Optionally, in production, the torque module 1 can be produced, assembled, and repaired as an independent torque module. Furthermore, since clearance fits can be used between the components, it is convenient to assemble the torque module 1 and the shaft assembly 2, thereby improving assembly efficiency, facilitating disassembly, and reducing maintenance costs.

[0130] Please refer to this as well. Figures 15-18 , Figure 15 This is a three-dimensional structural diagram of the rotating shaft assembly in one embodiment of this application. Figure 16 This is a three-dimensional structural diagram of the rotating shaft assembly in another embodiment of this application. Figure 17 This is a three-dimensional structural diagram of the hinge assembly of an electronic device in an unfolded state according to another embodiment of this application. Figure 18 This is a three-dimensional structural diagram of the rotating shaft assembly of an electronic device in a combined state according to another embodiment of this application.

[0131] This application also provides an electronic device 3, including two housings 31, a flexible screen 32, and a rotating shaft assembly 2 provided in this application. At least a portion of the two housings 31 are respectively disposed on opposite sides of the rotating shaft assembly 2. The housings 31 are connected to the rotating component 14 in the rotating shaft assembly 2. The flexible screen 32 is installed on one side of the housings 31 and the rotating component 14.

[0132] The electronic device 3 provided in this embodiment also includes a housing 31. The housing 31 is typically used to fix, support, or protect other components of the electronic device 3, and the housing 31 can even improve the appearance. The material of the housing 31 includes, but is not limited to, plastic, metal, etc. The housing 31 provided in this embodiment can be a component of any shape, and this application does not limit it, as long as the housing 31 is at least partially disposed on opposite sides of the rotating shaft assembly 2, and the housing 31 is connected to the rotating assembly 14. Optionally, the connection method between the housing 31 and the rotating assembly 14 includes, but is not limited to, threaded connection, snap-fit ​​connection, etc. In addition, since the housing 31 is connected to the rotating assembly 14, and at least part of the two housings 31 is disposed on opposite sides of the rotating shaft assembly 2, when the two rotating assemblies 14 rotate towards or away from each other, the two rotating assemblies 14 can drive the two housings 31 to rotate synchronously. The housing 31 can be directly connected to the rotating assembly 14, or indirectly connected through other components, such as transmission components, as long as the rotating assembly 14 can drive the housing 31 to rotate synchronously when it rotates.

[0133] The electronic device 3 provided in this embodiment also includes a flexible screen 32. The flexible screen 32 is typically used to display images, text, and other information. Because the flexible screen 32 is flexible, it can bend and deform under external force, and it can also recover its deformation, that is, return to the state before the external force was applied. The flexible screen 32 provided in this embodiment can be a component of any shape. This application does not limit this, as long as the flexible screen 32 is installed on one side of the housing 31 and the rotating assembly 14.

[0134] Since the flexible screen 32 is mounted on the housing 31 and the rotating assembly 14, when the two rotating assemblies 14 and the two housings 31 rotate, the rotating assemblies 14 and the housings 31 can cause the flexible screen 32 to deform; when the two rotating assemblies 14 and the two housings 31 are fixed, the flexible screen 32 is also fixed because the rotating shaft assembly 2 has a hovering and self-tightening function. Therefore, the electronic device 3 has both an unfolded state and a folded state. For example, Figure 15 As shown, the unfolded state refers to the flexible screen 32 being horizontally unfolded 180°, meaning the flexible screen 32 is not bent; as Figure 16As shown, the merged state refers to the flexible screen 32 being bent, and at least a portion of the flexible screen 32 having a gap. Furthermore, the hinge assembly 2 has been described in detail above, and will not be repeated here. It should be noted that when one or more hinge assemblies 2 are used in the electronic device 3, it is possible to drive other components to rotate and to hover via the hinge assembly 2.

[0135] like Figure 15 As shown, the electronic device 3 provided in this embodiment, by using the pivot assembly 2 provided in this application, can provide pressure and thus friction through the first elastic element 16. Therefore, compared with related technologies, it can not only improve the hovering and self-tightening effects, but also, when the same friction is required to achieve hovering, the pivot assembly 2 of this application can adopt a smaller size, improving the compactness of the pivot assembly 2 structure, reducing the internal space occupied by the pivot assembly 2 in the electronic device 3, thereby leaving more internal space for other components, improving the working performance of the electronic device 3, reducing the weight of the electronic device 3, reducing production costs, and improving the overall competitiveness of the electronic device 3. Furthermore, since the pivot assembly 2 in this embodiment can adopt a smaller size, the gap between the two torque modules 1 in the pivot assembly 2 is smaller. It can also be understood that by using a smaller size torque module 1, the bending radius of the pivot assembly 2 can be reduced, that is, the bending radius of the electronic device 3 can be reduced, thereby making the gap between the flexible screens 32 smaller after bending. That is, when the electronic device 3 is in a combined state, the gap between the flexible screens 32 on both sides is smaller, improving the appearance performance of the electronic device 3.

[0136] Optionally, in actual production, when the hinge assembly 2 is used in conjunction with the flexible screen 32, the gap between the hinges can be eliminated, enhancing the aesthetic appeal. This can be achieved, for example, by employing a teardrop-shaped hinge through a design with a mid-section and inclined plate structure. Simultaneously, various parameters within the electronic device 3 also affect the user experience and overall performance, such as the flatness of the screen support plate, the balance of overall torque, the wobbling experience of the mid-frame, and the gap effect between the mid-frame and the hinge 11. The hinge assembly 2 in this embodiment can improve the overall torque performance, thereby enhancing the usability of the electronic device 3.

[0137] The above provides a detailed description of the embodiments provided in this application. This document elucidates and explains the principles and implementation methods of this application. The above description is only intended to help understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
