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

[0015] 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.

[0016] On the other hand, the present invention provides 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;

[0017] 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.

[0018] 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:

[0019] The coil support is connected to the impact structure;

[0046] 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.

[0047] 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 3 It includes a stator assembly 1 and a rotating assembly 2, wherein:

[0048] One of the stator assembly 1 and the rotating assembly 2 is provided with a first magnet 11 and a second magnet 12 spaced apart along a first direction, and an arc-shaped magnetic guide plate 13 is provided between the first magnet 11 and the second magnet 12; the other of the stator assembly 1 and the rotating assembly 2 includes a coil 21, the rotating shaft 22 of the rotating assembly 2 is concentrically arranged with the center of the arc-shaped magnetic guide plate 13, the coil 21 is located between the first magnet 11 and the second magnet 12 and is arranged around the arc-shaped magnetic guide plate 13 (it can be understood that the coil 21 only surrounds the arc-shaped magnetic guide plate 13 but is not fixed to the arc-shaped magnetic guide plate 13); a spiral spring 4 is provided between the stator assembly 1 and the rotating assembly 2 for resetting the rotating assembly 2.

[0049] 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.

[0050] The oscillating motor of this embodiment includes a stator assembly 1 and a rotating assembly 2. One of the stator assembly 1 and the rotating assembly 2 is provided with a first magnet 11 and a second magnet 12 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, 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. The other 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 surrounds the arc-shaped magnetic guide plate 13. Compared with a conventional open magnetic circuit, this invention, by setting the first magnet 11 and the second magnet 12 and the coil 21 surrounding the arc-shaped magnetic guide plate 13, achieves a more efficient magnetic circuit. The arc-shaped magnetic guide plate 13 is arranged to reduce energy loss caused by magnetic field leakage, allowing the coil 21 to cut magnetic field lines to the maximum extent, and generating a larger rotational torque under the same current. Therefore, the torque of the rotating component 2 is increased when the current remains constant. A spiral spring 4 is provided between the stator component 1 and the rotating component 2 to reset the rotating component 2. The spiral spring 4 can not only use its spiral shape to avoid excessive stress on the spring sheet when the rotating component 2 swings at a large angle, ensuring the service life of the spring, but also stop the rotating component 2 in a fixed position (initial position). Resonance is achieved through a suitable driving frequency, which increases the torque of the rotating component 2 and enhances the swing control effect.

[0051] In some embodiments of the present invention, 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. Both ends of the arc-shaped magnetic guide plate 13 are connected to the first magnetic yoke 14 and the second magnetic yoke 15. In specific implementations, the first magnet 11 can be bonded and fixed to the first magnetic yoke 14, and the second magnet 12 can be bonded and 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 well achieved. At the same time, both ends of the arc-shaped magnetic guide plate 13 are connected to the first magnetic yoke 14 and the second magnetic yoke 15 (connected by magnetic connectors, specifically using conventional technology in the field). 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 have diffused 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, further enhancing the driving force on the coil 21, thereby enhancing the torque of the rotating assembly 2.

[0052] 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.

[0053] In some embodiments of the present invention, please refer to Figures 4a to 4cThe rotating assembly 2 has a rotating shaft 22 that is rotatably connected to the first magnetic yoke 14 and the second magnetic yoke 15. Specifically, it can be connected to the first magnetic yoke 14 and the second magnetic yoke 15 via a bearing 16. The reference numeral 141 in the figure is the bearing mounting hole. The rotating assembly 2 may also include a mass block 24 (which may be made of a heavy metal such as tungsten). The mass block 24 is located on the side of the coil 21 away from the rotating shaft 22. The spiral spring 4 is located on the side of the first magnetic yoke 14 away from the arc-shaped magnetic guide plate 13. The spiral spring 4 includes an inner fixing part 41, an outer fixing part 42, and a winding part 43 that connects the inner fixing part 41 and the outer fixing part 42. The inner fixing part 41 is fixed to the stator assembly 1, and the outer fixing part 42 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 of the rotating component 2 and the inertia of the rotational motion. When the oscillating motor is applied to the subsequent vibration device, it increases the impact force and shifts the center of gravity of the rotating component 2 away from the rotating shaft 22, making the rotating component 2 easier to drive. The inner fixing part 41 of the spiral spring 4 is fixed to the stator assembly 1, and the outer fixing part 42 is fixed to the mass block 24. After reaching resonance through a suitable driving frequency, the torque of the rotating component 2 is increased.

[0054] In some embodiments of the present invention, the inner fixing part 41 can be fixed to the stator assembly 1 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 groove 51 for accommodating the inner fixing part 41. During installation, the outer fixing part 42 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 groove 51 on the fixing block 5 is adjusted according to the angle of the inner fixing part 41 of the spiral spring 4. After that, the fixing block 5 is fixed to the stator assembly 1 (i.e., at the location where the first magnetic yoke 14 is installed on the rotating shaft 22). Finally, the outer fixing part 42 and the inner fixing part 41 of the spiral spring 4 are respectively fixed to the insertion groove 51 of the mass block 24 and the fixing block 5. 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 at the beginning and end of the spiral spring 4, so that the positions of the two ends (inner fixing part 41 and outer fixing part 42) 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 the shape. In the embodiment shown in the figure, the fixing block 5 is circular.

[0055] In specific implementation, to improve the installation firmness of the fixing block 5, the first magnetic yoke 14 is also provided with a fixing block receiving hole 142 at the bearing mounting hole 141. The inner ring of the bearing 16 is connected to the rotating shaft 22 of the rotating assembly 2, the lower part of the outer ring of the bearing 16 is fixedly connected to the bearing mounting hole 141, and the upper part of the outer ring of the bearing 16 protrudes from the fixing block receiving hole 142. The lower end face of the fixing block 5 is provided with a bearing receiving hole 52. During installation, the fixing block 5 is placed in the fixing block receiving hole 142, and the inner side wall of the bearing receiving hole 52 is fixedly connected to the upper part of the outer ring of the bearing 16 by means of adhesive or welding, and the lower end face of the fixing block 5 is fixedly connected to the bottom wall of the fixing block receiving hole 142. In this way, the fixing block 5 is fixed to the stator assembly 1 (i.e., at the mounting shaft 22 of the first magnetic yoke 14), and is simultaneously fixedly connected to the outer ring of the bearing 16 and the first magnetic yoke 14. The structure is compact, the overall volume is reduced, and the firmness is good.

[0056] In some embodiments of the present invention, please refer to Figure 3 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 3 In 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.

[0057] On the other hand, embodiments of the present invention provide a vibration device 100, such as... Figures 1a to 5c 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.

[0058] 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. One of the stator assembly 1 and the rotating assembly 2 is provided with a first magnet 11 and a second magnet 12 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, 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. The other of the stator assembly 1 and the rotating assembly 2 includes a coil 21. The coil 21 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 a conventional open magnetic circuit, this invention, by setting the first magnet 11 and the second magnet 12 and the coil 21... The surrounding arc-shaped magnetic guide plate 13 is arranged to reduce energy loss caused by magnetic field leakage, allowing the coil 21 to cut magnetic field lines to the maximum extent, and generating a larger rotational torque under the same current. Therefore, the torque of the rotating component 2 and the overall vibration force of the vibration device 100 are increased without changing the current. A spiral spring 4 is provided between the stator component 1 and the rotating component 2 to reset the rotating component 2. The spiral spring 4 can not only use its spiral shape to avoid excessive stress on the spring sheet when the rotating component 2 swings at a large angle, ensuring the service life of the spring, but also stop the rotating component 2 in a fixed position (initial position). Resonance is achieved through a suitable driving frequency, which increases the torque of the rotating component 2, enhances the swing control effect, and thus improves the overall vibration force of the vibration device 100.

[0059] In some embodiments of the present invention, the rotating component 2 may further 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 subjected 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 selecting a stronger first magnet 11 and a stronger second magnet 12, thereby generating a strong and clear force when impacting the braking part.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] 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.

[0065] In some embodiments of the present invention, such as Figures 1a to 2 As shown, the vibration module 101 may further include a housing 6, with adjacent side walls of the housing 6 forming braking portions. In a specific implementation, 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. The adjacent second side walls 622 serve as braking portions. Thus, by utilizing the adjacent side walls (i.e., adjacent second side walls 622) of the housing 6 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.

[0066] 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 5a to 5c The embodiment shown is this structure, wherein, Figure 5a For limit state 1, Figure 5b In its natural state, Figure 5cThis is extreme state 2. In extreme state 1, the motor force cancels out, and there is no overall force. In extreme state 2, the motor force is downward, and the overall force is downward. 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; and 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 strike 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, so there is no force felt in the normal direction of the second limiting surface or the felt force is very small. 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.

[0067] 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.
