Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a swing motor and a vibration device. Background Technology

[0002] Traditional vibration devices generate the illusion of a force "as if it were moving in a certain direction" by continuously producing asymmetrical vibrations; this type of vibration is also known as anisotropic vibration. Currently, there are two methods to achieve this sense of force: one is to input an asymmetrical signal into a linear resonator and use human senses to create an illusion; the other is to generate a sense of force by rotating an unbalanced rotating component and then rapidly braking the rotating component. However, existing anisotropic vibration devices usually have limited torque, which limits the rotational speed of the rotating component and affects the sense of force from the vibration device. Summary of the Invention

[0003] This invention provides a swing motor with high torque.

[0004] The present invention also provides a vibration device with high torque and strong vibration force.

[0005] The technical solution provided by this invention is as follows:

[0006] On one hand, embodiments of the present invention provide an oscillating motor, including a stator assembly and a rotating assembly, wherein:

[0007] One of the stator assembly and the rotating assembly is provided with a first magnet and a second magnet at intervals along a first direction. An arc-shaped magnetic guide plate is provided between the first magnet and the second magnet. A first magnetic yoke is provided on the side of the first magnet away from the arc-shaped magnetic guide plate. The first magnet is fixed to the first magnetic yoke. A second magnetic yoke is provided on the side of the second magnet away from the arc-shaped magnetic guide plate. The second magnet is fixed to the second magnetic yoke.

[0008] The stator assembly and the rotating assembly each include a coil. The axis of rotation of the rotating assembly is concentric with the center of the arc-shaped magnetic guide plate. The coil is located between the first magnet and the second magnet and surrounds the arc-shaped magnetic guide plate.

[0009] The first magnetic yoke, the arc-shaped magnetic guide plate, and the second magnetic yoke are provided with magnetic guide connectors at both ends along the swing direction of the rotating assembly. The magnetic guide connectors include a first connector connecting the first magnetic yoke and the arc-shaped magnetic guide plate, and a second connector connecting the arc-shaped magnetic guide plate and the second magnetic yoke. The first connector and the second connector form a complementary insertion structure for inserting the end of the arc-shaped magnetic guide plate.

[0010] In some embodiments of the present invention, the first connector has a first notch at one end facing the arc-shaped magnetic guide plate, the second connector has a second notch at one end facing the arc-shaped magnetic guide plate, and the arc-shaped magnetic guide plate has protrusions at both ends. The ends of the first connector and the second connector facing the arc-shaped magnetic guide plate abut against each other, thereby forming receiving openings at the first notch and the second notch for accommodating the protrusions.

[0011] In some embodiments of the present invention, the receiving port is a C-shaped opening facing the direction of the rotating shaft, or the receiving port is a C-shaped opening facing away from the direction of the rotating shaft, or the receiving port is a closed square opening.

[0012] In some embodiments of the present invention, both the first magnet and the second magnet are magnetized along the first direction but in opposite directions.

[0013] And / or, both the first magnet and the second magnet are arc-shaped and concentrically arranged with the center of the arc-shaped magnetic guide plate.

[0014] On the other hand, embodiments of the present invention provide a vibration device, including at least one vibration module, the vibration module including a braking part and the above-mentioned swing motor, and the rotating component is further provided with an impact structure;

[0015] The braking part is located on the rotation path of the rotating assembly, and the rotating assembly can rotate to the position of the braking part so that the impact structure impacts the braking part to generate a force.

[0016] In some embodiments of the present invention, the stator assembly includes the first magnet and the second magnet, the rotating assembly includes the coil, and the rotating shaft of the rotating assembly is rotatably connected to the first yoke and the second yoke.

[0017] In some embodiments of the present invention, the rotating assembly further includes a coil support, the coil being disposed on the coil support, and the coil support being a non-magnetic structure, wherein:

[0018] The coil support is connected to the impact structure;

[0019] Alternatively, the coil support and the impact structure can be designed as a single unit.

[0020] In some embodiments of the present invention, the coil support includes a connecting plate and two clamping plates, the rotating shaft is connected to the connecting plate, the two ends of the connecting plate are connected to the two clamping plates, and the coil is disposed between the two clamping plates.

[0021] In some embodiments of the present invention, the rotating assembly further includes a mass block located on the side of the coil away from the rotating shaft, and the vibration module further includes a spiral spring located on the side of the first magnetic yoke away from the arc-shaped magnetic guide plate, with one end of the spiral spring fixed to the stator assembly and the other end fixed to the mass block.

[0022] In some embodiments of the present invention, at least one of the two surfaces of the braking part and the impact structure that collide with each other is provided with a buffer.

[0023] And / or, the vibration module further includes a housing, the adjacent side walls of which form the braking portion.

[0024] The present invention has the following beneficial effects:

[0025] The oscillating motor and vibration device of this invention include a stator assembly and a rotating assembly. A first magnet and a second magnet are spaced apart along a first direction in one of the stator assembly and the rotating assembly. An arc-shaped magnetic guide plate is provided between the first magnet and the second magnet, so that the magnetic fields generated by the first magnet and the second magnet are directionally conducted along the arc-shaped magnetic guide plate. A first magnetic yoke is provided on the side of the first magnet away from the arc-shaped magnetic guide plate, and the first magnet is fixed to the first magnetic yoke. A second magnetic yoke is provided on the side of the second magnet away from the arc-shaped magnetic guide plate, and the second magnet is fixed to the second magnetic yoke. This effectively achieves the installation and fixation of the first magnet and the second magnet. Under the action of the arc-shaped magnetic guide plate and the first magnetic yoke, the magnetic field that the first magnet might otherwise diffuse outward is constrained between the two, reducing magnetic leakage and enhancing the magnetic field. Similarly, the magnetic field between the arc-shaped magnetic guide plate and the second magnetic yoke is also enhanced, thereby enhancing the torque of the rotating assembly. The first magnetic yoke, the arc-shaped magnetic guide plate, and the second magnetic yoke are arranged along the oscillation direction of the rotating assembly. The stator assembly is equipped with a magnetically conductive connector, which includes a first connector connecting the first magnetic yoke and the arc-shaped magnetic plate, and a second connector connecting the arc-shaped magnetic plate and the second magnetic yoke. The first and second connectors form a complementary insertion structure for inserting the end of the arc-shaped magnetic plate. This further reduces magnetic leakage, enhances the magnetic field, and thus enhances the torque of the rotating assembly. At the same time, the middle magnetic yoke (arc-shaped magnetic plate) adopts a transverse insertion design, which reduces the assembly difficulty while ensuring the continuity of the magnetic circuit. The other component of the stator assembly and the rotating assembly includes a coil, which is located between the first magnet and the second magnet and surrounds the arc-shaped magnetic plate. Compared with the traditional open magnetic circuit, this invention reduces energy loss caused by magnetic field leakage by setting the first magnet and the second magnet and the coil surrounding the arc-shaped magnetic plate. This allows the coil to cut magnetic field lines to the maximum extent and generate a larger rotational torque under the same current. Therefore, the torque of the rotating assembly is further increased while the current remains constant. Attached Figure Description

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0050] On one hand, embodiments of the present invention provide a swing motor (also known as an arc voice coil motor), which is not shown separately; please refer to [the original text]. Figures 2 to 4 It includes a stator assembly 1 and a rotating assembly 2, wherein:

[0051] In the stator assembly 1 and the rotating assembly 2, a first magnet 11 and a second magnet 12 are spaced apart along a first direction. An arc-shaped magnetic guide plate 13 is provided between the first magnet 11 and the second magnet 12. A first magnetic yoke 14 is provided on the side of the first magnet 11 away from the arc-shaped magnetic guide plate 13, and the first magnet 11 is fixed to the first magnetic yoke 14. A second magnetic yoke 15 is provided on the side of the second magnet 12 away from the arc-shaped magnetic guide plate 13, and the second magnet 12 is fixed to the second magnetic yoke 15. In a specific implementation, the first magnet 11 can be glued and fixed to the first magnetic yoke 14, and the second magnet 12 can be glued and fixed to the second magnetic yoke 15.

[0052] The stator assembly 1 and the rotating assembly 2 each include a coil 21. The rotating shaft 22 of the rotating assembly 2 is concentrically arranged with the center of the arc-shaped magnetic plate 13. The coil 21 is located between the first magnet 11 and the second magnet 12 and surrounds the arc-shaped magnetic plate 13 (it can be understood that the coil 21 only surrounds the arc-shaped magnetic plate 13 but is not fixed to the arc-shaped magnetic plate 13). The first magnetic yoke 14, the arc-shaped magnetic plate 13 and the second magnetic yoke 15 are provided with magnetic connecting members at both ends along the swing direction of the rotating assembly 2. The magnetic connecting members include a first connecting member 141 connecting the first magnetic yoke 14 and the arc-shaped magnetic plate 13, and a second connecting member 151 connecting the arc-shaped magnetic plate 13 and the second magnetic yoke 15. The first connecting member 141 and the second connecting member 151 form a complementary insertion structure for the end of the arc-shaped magnetic plate 13 to be inserted.

[0053] When in operation, the coil 21 generates a magnetic field when energized. This magnetic field interacts with the constant magnetic fields of the first magnet 11 and the second magnet 12. The constant magnetic fields generated by the first magnet 11 and the second magnet 12 then apply an Ampere force to the coil 21, thereby driving the rotating component 2 to rotate. When the driving electrical signal of the coil 21 is an alternating signal (current with a periodically changing direction), the direction of the magnetic field lines of the magnetic field generated by the coil 21 changes periodically, causing the direction of the interacting magnetic force to change periodically as well. This changes the rotation direction of the rotating component 2, causing it to reciprocate.

[0054] The oscillating motor of this invention includes a stator assembly 1 and a rotating assembly 2. A first magnet 11 and a second magnet 12 are spaced apart along a first direction in either the stator assembly 1 or the rotating assembly 2. An arc-shaped magnetic guide plate 13 is provided between the first magnet 11 and the second magnet 12, so that the magnetic field generated by the first magnet 11 and the second magnet 12 is directionally conducted along the arc-shaped magnetic guide plate 13. A first magnetic yoke 14 is provided on the side of the first magnet 11 away from the arc-shaped magnetic guide plate 13, and the first magnet 11 is fixed to the first magnetic yoke 14. A second magnet 12 is provided on the side away from the arc-shaped magnetic guide plate 13. A second magnetic yoke 15 is provided, and a second magnet 12 is fixed to the second magnetic yoke 15. This effectively achieves the installation and fixation of the first magnet 11 and the second magnet 12. Under the action of the arc-shaped magnetic guide plate 13 and the first magnetic yoke 14, the magnetic field that the first magnet 11 might otherwise diffuse outwards is constrained between the two, reducing magnetic leakage and enhancing the magnetic field. Similarly, the magnetic field between the arc-shaped magnetic guide plate 13 and the second magnetic yoke 15 is also enhanced, thereby increasing the torque of the rotating assembly 2. The first magnetic yoke 14, the arc-shaped magnetic guide plate 13, and the second magnetic yoke 15 swing along the direction of the rotating assembly 2. Magnetic connecting parts are provided at both ends of the rotating assembly. These connecting parts include a first connecting part 141 connecting the first magnetic yoke 14 and the arc-shaped magnetic plate 13, and a second connecting part 151 connecting the arc-shaped magnetic plate 13 and the second magnetic yoke 15. The first connecting part 141 and the second connecting part 151 form a complementary insertion structure for inserting the end of the arc-shaped magnetic plate 13. This further reduces magnetic leakage, enhances the magnetic field, and thus increases the torque of the rotating assembly 2. Simultaneously, the middle magnetic yoke (arc-shaped magnetic plate 13) adopts a transverse insertion design, which reduces magnetic leakage while ensuring the continuity of the magnetic circuit. The assembly difficulty is reduced; one of the stator assembly 1 and the rotating assembly 2 includes a coil 21, which is located between the first magnet 11 and the second magnet 12 and is arranged around the arc-shaped magnetic guide plate 13. Compared with the traditional open magnetic circuit, the present invention reduces the energy loss caused by magnetic field leakage by setting the first magnet 11 and the second magnet 12 and the coil 21 around the arc-shaped magnetic guide plate 13. This allows the coil 21 to cut the magnetic field lines to the maximum extent and generate a larger rotational torque under the same current. Therefore, the torque of the rotating assembly 2 is further increased when the current remains unchanged.

[0055] In some embodiments of the present invention, please refer to Figures 2 to 3cThe first connector 141 has a first notch at one end facing the arc-shaped magnetic plate 13, and the second connector 151 has a second notch at one end facing the arc-shaped magnetic plate 13. The arc-shaped magnetic plate 13 has protrusions 131 at both ends. The ends of the first connector 141 and the second connector 151 facing the arc-shaped magnetic plate 13 abut against each other, thereby forming receiving openings 132 at the first and second notches to accommodate the protrusions 131. In this embodiment, the complementary insertion structure forms the receiving openings 132 through the first and second notches. This not only constitutes a stable complementary insertion structure but also facilitates the lateral insertion of the protrusions 131 at both ends of the arc-shaped magnetic plate 13 into the receiving openings 132, reducing assembly difficulty.

[0056] In specific implementations, the first connector 141 and the first magnetic yoke 14 can be an integral structure (formed by bending sheet metal), or the first connector 141 can be an independent component welded or screwed onto the first magnetic yoke 14; the second connector 151 and the second magnetic yoke 15 can also be an integral structure (formed by bending sheet metal), or the second connector 151 can be an independent component welded or screwed onto the second magnetic yoke 15. In the embodiment shown in the figure, the first connector 141 and the first magnetic yoke 14 are an integral structure, and the second connector 151 and the second magnetic yoke 15 are an integral structure. The first connector 141 and the second connector 151, as well as the receiving port 132 and the protrusion 131 of the arc-shaped magnetic guide plate 13, are all welded connections. In this way, a firm connection can be achieved, and each magnetic yoke is welded to the arc-shaped magnetic guide plate 13. Compared with screw fixing, the end magnetic circuit will not be damaged, effectively ensuring the magnetic field strength.

[0057] In some embodiments of the present invention, the receiving opening 132 can be a C-shaped opening facing the direction of the rotating shaft 22, or a C-shaped opening facing away from the direction of the rotating shaft 22, or a closed square opening, as long as it allows the protrusions 131 at both ends of the arc-shaped magnetic plate 13 to be inserted laterally, and is not limited here. In the embodiment shown in the figure, the receiving opening 132 is a C-shaped opening facing away from the direction of the rotating shaft 22.

[0058] In some embodiments of the present invention, please refer to Figure 4 The first magnet 11 and the second magnet 12 can both be magnetized along the first direction but in opposite directions. Since the magnetization directions of the first magnet 11 and the second magnet 12 are opposite, the magnetic field force exerted by the magnetic field generated by the first magnet 11 and the second magnet 12 on the coil 21 is in the same direction. The force on the coil 21 increases, which increases the torque of the rotating component 2 and increases the rotation speed of the rotating component 2. When the swing motor is applied to the subsequent vibration device, it can increase the impact force when the rotating component 2 collides with the braking part and improve the vibration. Figure 4In the diagram, A represents the magnetization direction of the magnet, and B represents the current direction of the coil 21. The effective portion of the coil consists of its two long sides (i.e., the parts parallel to the magnet). This flattened structural design results in a smaller overall size. The first magnet 11 and the second magnet 12 can both be arc-shaped and concentrically positioned with the center of the arc-shaped magnetic guide plate 13. This ensures that the magnetic field is evenly distributed along the rotation path of the rotating assembly 2, making the coil 21 more stable under force during rotation.

[0059] On the other hand, embodiments of the present invention provide a vibration device 100, such as... Figures 1a to 6c As shown, it includes at least one vibration module 101, which includes a braking part and the aforementioned swing motor. The rotating assembly 2 is also provided with an impact structure. The braking part is located in the rotation path of the rotating assembly 2, and the rotating assembly 2 can rotate to the position of the braking part so that the impact structure impacts the braking part to generate a force. The structure of the swing motor is the same as above, and will not be described again here.

[0060] The vibration device 100 of this embodiment includes at least one vibration module 101. The vibration module 101 includes a braking part and a swing motor. The swing motor includes a stator assembly 1 and a rotating assembly 2. A first magnet 11 and a second magnet 12 are spaced apart along a first direction in one of the stator assembly 1 and the rotating assembly 2. An arc-shaped magnetic guide plate 13 is provided between the first magnet 11 and the second magnet 12, so that the magnetic field generated by the first magnet 11 and the second magnet 12 is directionally conducted along the arc-shaped magnetic guide plate 13. A first magnetic yoke 14 is provided on the side of the first magnet 11 away from the arc-shaped magnetic guide plate 13, and the first magnet 11 is fixed to the first magnetic yoke 14. A second magnetic yoke 15 is provided on the side away from the arc-shaped magnetic guide plate 13, and the second magnet 12 is fixed to the second magnetic yoke 15. In this way, the installation and fixation of the first magnet 11 and the second magnet 12 are better realized. Under the action of the arc-shaped magnetic guide plate 13 and the first magnetic yoke 14, the magnetic field of the first magnet 11 that might originally diffuse outward is constrained between the two, reducing magnetic leakage and enhancing the magnetic field. Similarly, the magnetic field between the arc-shaped magnetic guide plate 13 and the second magnetic yoke 15 is also enhanced, thereby enhancing the torque of the rotating assembly 2 and the overall vibration force of the vibration device 100; the first magnetic yoke 14, the arc-shaped magnetic guide plate 13 and the second magnetic yoke 15 along the rotating assembly Component 2 has magnetically conductive connectors at both ends in the swing direction. These connectors include a first connector 141 connecting the first magnetic yoke 14 and the arc-shaped magnetic plate 13, and a second connector 151 connecting the arc-shaped magnetic plate 13 and the second magnetic yoke 15. The first connector 141 and the second connector 151 form a complementary insertion structure for inserting the end of the arc-shaped magnetic plate 13. This further reduces magnetic leakage, enhances the magnetic field, and thus strengthens the torque of the rotating assembly 2, as well as the overall vibration force of the swing motor. Simultaneously, the middle magnetic yoke (arc-shaped magnetic plate 13) adopts a transverse insertion design, ensuring the continuity of the magnetic circuit. Based on this, the assembly difficulty is reduced; one of the stator assembly 1 and the rotating assembly 2 includes a coil 21, which is located between the first magnet 11 and the second magnet 12 and is arranged around the arc-shaped magnetic guide plate 13. Compared with the traditional open magnetic circuit, the present invention, by setting the first magnet 11 and the second magnet 12 and the coil 21 around the arc-shaped magnetic guide plate 13, can reduce the energy loss caused by magnetic field leakage, and enable the coil 21 to cut the magnetic field lines to the maximum extent. Under the same current, it can generate a larger rotational torque. Therefore, under the condition of constant current, the torque of the rotating assembly 2 is further increased, and the overall vibration force of the vibration device 100 is improved.

[0061] In some embodiments of the present invention, the stator assembly 1 may include a first magnet 11 and a second magnet 12, and the rotating assembly 2 includes a coil 21. In this case, the coil 21, as part of the rotating assembly 2, can rotate about the rotation axis 22 of the rotating assembly 2. Alternatively, the stator assembly 1 may include the coil 21, and the rotating assembly 2 may include the first magnet 11 and the second magnet 12, that is, the first magnet 11 and the second magnet 12, as parts of the rotating assembly 2, can rotate about the rotation axis 22 of the rotating assembly 2. The present invention does not limit this, and the positions of the coil 21 and the first magnet 11 and the second magnet 12 can be interchanged according to actual needs. The following description will take the rotating assembly 2 including the coil 21 as an example.

[0062] In some embodiments of the present invention, the rotating shaft 22 of the rotating assembly 2 is rotatably connected to the first magnetic yoke 14 and the second magnetic yoke 15, specifically via a bearing 16. The rotating assembly 2 may also include a coil support 23, with the coil 21 disposed on the coil support 23, which is a non-magnetic structure. The coil support 23 is made of a non-magnetic material, such as wood, plastic, ceramic, rubber, stainless steel, copper, aluminum, titanium, etc., and is not limited thereto. By using a non-magnetic material to make the coil support 23, the coil support 23 is not subject to the magnetic force of the constant magnetic field generated by the first magnet 11 and the second magnet 12. There is no static magnetic torque between the rotating component 2 and the stator component 1. The stator component 1 only applies a magnetic force to the rotating component 2 when the coil 21 is energized. With this configuration, when the current in the coil 21 remains constant, the rotational force applied to the rotating component 2 remains constant, and the rotating component 2 can rotate continuously with a constant torque. It is easy to drive the rotating component 2 to rotate at a higher speed by increasing the current or using a stronger first magnet 11 and a second magnet 12, thereby generating a strong and clear force when impacting the braking part.

[0063] Therefore, it is understood that in the technical solution of this application, the vibration module 101 includes a cooperating stator assembly 1 and a rotating assembly 2. The stator assembly 1 and the rotating assembly 2 are driven to rotate by the principle of electromagnetic induction and Ampere force. A first magnet 11 and a second magnet 12 are provided on the stator assembly 1. The rotating assembly 2 includes a coil support 23 and a coil 21 fixed on the coil support 23. The coil 21 is located in the constant magnetic field of the first magnet 11 and the second magnet 12. With this arrangement, when the coil 21 is energized, the constant magnetic field generated by the first magnet 11 and the second magnet 12 will apply an Ampere force to the coil 21, thereby driving the rotating assembly 2 to rotate. When the rotating assembly 2 rotates to its limit position, it will collide with the braking part provided on the stator assembly 1 to achieve asymmetrical vibration and generate a linear force. In this case, an alternating current with a continuously changing current direction can be input into the coil 21 to generate a changing magnetic field and drive the rotating assembly 2 to rotate back and forth to repeatedly strike the braking part. At the same time, the coil support 23 of the rotating component 2 is a non-magnetic structure. The coil support 23 will not be affected by the magnetic force generated by the first magnet 11 and the second magnet 12. The rotating component 2 will not be affected by the static magnetic torque. At this time, the driving force of the rotating component 2 is only the Ampere force on the coil 21. When the current in the coil 21 remains constant, the rotational force applied to the rotating component 2 remains constant. The rotating component 2 can rotate continuously with a constant torque. It is easy to drive the rotating component 2 to rotate at a higher speed by increasing the current or selecting the first magnet 11 and the second magnet 12 with stronger magnetic force, thereby generating a strong and clear force when impacting the braking part.

[0064] Furthermore, the vibration device 100 may be provided with two or more vibration modules 101, and the vibration device 100 may generate a rotational force or a stronger linear force through the force sensation combination of different vibration modules 101.

[0065] In some embodiments of the present invention, such as Figure 2 As shown, the coil support 23 may include a connecting plate 231 and two clamping plates 232. A rotating shaft 22 is connected to the connecting plate 231, and both ends of the connecting plate 231 are connected to the two clamping plates 232. The coil 21 is disposed between the two clamping plates 232. In a specific implementation, the connecting plate 231 and the two clamping plates 232 can be an integral structure. The rotating shaft 22 can be connected to the inner side or the outer side of the connecting plate 231. In the embodiment shown in the figure, a connecting block (not shown) is installed on the inner side of the connecting plate 231, and the rotating shaft 22 is installed in the connecting block. In this way, the connecting plate 231 and the two clamping plates 232 together form a robust rigid frame. The rotating shaft 22 is installed at the center of the connecting plate 231, which makes torque transmission efficient and the structure stress balanced.

[0066] In some embodiments of the present invention, the rotating component 2 may further include a mass block 24 located on the side of the coil 21 away from the rotating shaft 22. The vibration module 101 also includes a spiral spring 4 located on the side of the first magnetic yoke 14 away from the arc-shaped magnetic guide plate 13. One end of the spiral spring 4 is fixed to the stator component 1, and the other end is fixed to the mass block 24. Thus, the mass block 24 is located on the side of the coil 21 away from the rotating shaft 22, increasing the mass and inertia of the rotating component 2, increasing the impact force, and shifting the center of gravity of the rotating component 2 away from the rotating shaft 22, making the rotating component 2 easier to drive, thereby improving the rotational torque of the rotating component 2 and the vibration force of the vibration module 101. The spiral spring 4 not only uses its spiral shape to prevent excessive stress on the spring sheet when the rotating component 2 swings at large angles, ensuring the service life of the spring, but also allows the rotating component 2 to stop at a fixed position (initial position), achieving resonance through a suitable driving frequency, thus improving the vibration sensation. Specifically, the mass block 24 may be made of a heavy metal such as tungsten.

[0067] In specific implementation, one end of the spiral spring 4 can be fixed to the stator assembly 1 (specifically, the first magnetic yoke 14) by a fixing block 5. The fixing block 5 is concentrically arranged with the rotating shaft 22, and the fixing block 5 is provided with a insertion slot 51 for accommodating the end of the spiral spring 4. During installation, one end of the spiral spring 4 is temporarily placed on the mass block 24 at a preset initial position. Then, the rotation position / angle of the insertion slot 51 on the fixing block 5 is adjusted according to the angle of the other end of the spiral spring 4. After that, the fixing block 5 is fixed to the first magnetic yoke 14. Finally, both ends of the spiral spring 4 are fixed to the insertion slots 51 of the mass block 24 and the fixing block 5, respectively. At this time, the spiral spring 4 is in a natural state without force. Thus, the rotatable and adjustable fixing block 5 absorbs the tolerance in the circumferential direction caused by the processing of the beginning and end of the spiral spring 4, so that the positions of the two ends of the spiral spring 4 can be correctly assembled. The fixing block 5 can be square, circular, or other shapes. This invention does not limit this. In the embodiment shown in the figure, the fixing block 5 is circular.

[0068] In some embodiments of the present invention, the coil support 23 can be connected to the impact structure. Alternatively, as shown in the embodiment in the figure, the coil support 23 and the impact structure are designed as a single unit. Specifically, the mass block 24 is disposed between the two clamping plates 232, and the mass block 24 and the two clamping plates 232 form an impact structure on both sides along the swing direction of the rotating component 2. In this way, the force transmission is more direct, and the overall strength can be improved. By using the mass block 24 and the two clamping plates 232 to form an impact structure on both sides along the swing direction of the rotating component 2, the impact structure does not need to be added separately, and the volume of the rotating component 2 is further reduced, thus reducing costs.

[0069] In some embodiments of the present invention, at least one of the two surfaces of the braking part and the impact structure that collide with each other is provided with a buffer member 3. In specific implementations, the buffer member 3 can be a soft or elastic structure such as foam, airbag, or rubber. The buffer member 3 can be provided on the braking part, on the impact structure, or on both the braking part and the impact structure. In this way, rigid collisions between the impact structure and the braking part can be avoided, and the impact force can be buffered by the buffer member 3, preventing multiple collisions between the impact structure and the braking part from causing significant damage.

[0070] In some embodiments of the present invention, as shown in Figures 1-2, the vibration module 101 may further include a housing 6, with adjacent side walls of the housing 6 forming braking portions. Specifically, the housing 6 includes a first housing 61 and a second housing 62. The first housing 61 includes a top wall 611 and a pair of adjacent first side walls 612, and the second housing 62 includes a bottom wall 621 and a pair of adjacent second side walls 622, with the adjacent second side walls 622 serving as braking portions. Thus, by utilizing the adjacent side walls of the housing 6 (i.e., adjacent second side walls 622) to form braking portions, a separate, independent braking portion is unnecessary, reducing the number of components used in the vibration module 101 and lowering costs.

[0071] In some embodiments of the present invention, the vibration device 100 includes at least two vibration modules 101, wherein the at least two vibration modules 101 are arranged axially symmetrically, and the rotation directions of the rotation components 2 of the two vibration modules 101 are opposite. Figures 6a to 6c The embodiment shown illustrates this structure, where F represents the impact force of the rotating component. Figure 6a For limit state 1, Figure 6b In its natural state, Figure 6c In extreme state 2, the motor force cancels out in extreme state 1, resulting in no overall force. In extreme state 2, the motor force is downward, resulting in an overall downward force. The rotating component 2 vibrates cyclically, and the overall force feels downward. Specifically, the two mutually perpendicular limiting surfaces in each vibration module 101 can be defined as the first limiting surface and the second limiting surface. When the two vibration modules 101 are axially symmetrically arranged, the first limiting surfaces of the two vibration modules 101 face the same direction, and the two second limiting surfaces are opposite or back-to-back. Furthermore, the rotation directions of the rotating components 2 of the two vibration modules 101 are opposite. With this arrangement, when the two rotating components 2 simultaneously impact the corresponding first limiting surface, the centrifugal force of the rotating component 2 disappears, leaving only the braking force in the normal direction of the first limiting surface. The braking forces in the two vibration modules 101 are in opposite directions, causing the two braking forces to cancel each other out, resulting in no or minimal force felt in the normal direction of the second limiting surface. When the two rotating components 2 simultaneously strike the corresponding second limiting surface, the external manifestation is the resultant force of the two braking forces, generating a downward linear force.

[0072] Alternatively, the vibration device 100 includes at least two vibration modules 101, wherein the at least two vibration modules 101 are arranged centrally symmetrically, the rotation directions of the rotating components 2 of the two vibration modules 101 are the same, and they can simultaneously impact the corresponding braking parts to generate a rotational force. In this case, the surfaces of the two braking parts in each vibration module 101 that act with the buffer 3 are defined as a first limiting surface and a second limiting surface, respectively, wherein the first limiting surfaces of the two vibration modules 101 face opposite directions, and the two second limiting surfaces also face opposite directions; and the rotation directions of the rotating components 2 of the two vibration modules 101 are the same. With this arrangement, when the rotating components 2 of the two vibration modules 101 simultaneously impact the corresponding first limiting surface or simultaneously impact the corresponding second limiting surface, since the braking forces of the two vibration devices 100 are opposite and not on the same straight line, the vibration device 100 can generate a rotational force.
