[0046] The present application provides a vibration device 1 .
[0047] Please refer to Figures 1 to 5 In some embodiments of the present application, the vibration device 1 includes at least one vibration module 100, and the vibration module 100 includes:
[0048] A stator assembly 10, wherein the stator assembly 10 is provided with at least one coil 11 and a stopper 135; and
[0049] The rotating component 30 is rotatably disposed on the side of the coil 11. The rotating component 30 is provided with a magnet 31. The magnetization direction of the magnet 31 and the direction of the rotating shaft 35 of the rotating component 30 are both perpendicular to the winding plane of the coil 11, so that the rotating component 30 can be rotated to the position of the limiting portion 135 to collide with the limiting portion 135 to generate a force sense.
[0050] In the embodiment of the present application, the vibration device 1 includes a stator component 10 and a rotating component 30, wherein the stator component 10 is provided with at least one coil 11; the rotating component 30 is rotatably arranged on one side of the coil 11, and the extension direction of the rotating shaft 35 of the rotating component 30 is perpendicular to the winding surface where the coil 11 is located, and at least one limiting portion 135 is arranged on the stator component 10, and the limiting portion 135 is arranged on the rotation path of the rotating component 30; the rotating component 30 includes at least a magnet 31, and may also include a bracket, a mass block 33 and other structures for fixing the magnet 31, wherein the magnetization direction of the magnet 31 is consistent with the direction of the rotating shaft 35 of the rotating component 30, that is, one of the magnetic poles of the magnet 31 is arranged toward the coil 11. In this way, when the coil 11 is energized, a magnetic field will be generated, so that the magnet 31 is acted upon by the magnetic field force and drives the entire rotating component 30 to rotate. When the rotating component 30 rotates to the extreme position, it will collide with the side limiting portion 135 and generate a linear force sense in the impact direction. An alternating current can be input into the coil 11 of the stator device to cause the coil 11 to generate a changing magnetic field, causing the direction of the magnetic flux lines to change repeatedly, thereby driving the rotating component 30 to rotate in different directions. In some embodiments, two limit portions 135 spaced apart along the rotation direction of the rotating component 30 can be provided on the stator component 10, so that the stator component 10 can reciprocately collide with the two limit portions 135 to generate linear force sensations in different directions.
[0051] In the embodiment of the present application, at least two vibration modules 100 may be provided in the vibration device 1, so that there are at least two vibration modules 100 with a centrally symmetrical structure. When the rotation directions of the rotating components 30 of the two vibration modules 100 are consistent and they hit the corresponding limiting parts 135 at the same time, the braking forces in the two vibration modules 100 are opposite in direction and are not on the same straight line. At this time, the two braking forces form a torque together, so that the vibration device 1 can generate a sense of rotational force.
[0052] In addition, in the embodiment of the present application, at least two of the vibration modules 100 can be provided with limiting surfaces 1351 facing the same direction, so that the rotating components 30 in some of the vibration modules 100 can simultaneously hit the corresponding limiting surfaces 1351 to generate a linear force sensation in the same direction. The linear force sensation generated by the vibration device 1 can be made stronger by superposition of the linear force sensations in multiple vibration modules 100.
[0053] The structures such as the vibration module 100 and the vibration device 1 proposed in the embodiments of the present application use the principles of electromagnetic induction and Lorentz force to drive the rotating component 30 to rotate, and the coil 11 is arranged on the side of the rotating component 30; compared with the structural setting of using a motor to drive the eccentric weight to rotate, the structure of the vibration device 1 is more compact and relatively small in size, which can be applied to more usage environments, thereby improving the applicability of the vibration device 1.
[0054] Therefore, it can be understood that the technical solution of the present application is that the vibration device 1 includes a stator component 10 and a rotating component 30 that match each other. The rotating component 30 is arranged on one side of the coil 11 of the stator component 10, and a magnet 31 is correspondingly arranged on the rotating component 30; when the coil 11 is energized, a magnetic field can be generated to apply a magnetic field force to the magnet 31, thereby driving the rotating component 30 to rotate. When the rotating component 30 rotates to the extreme position, it will collide with the limit part 135 set on the stator component 10 to generate a force sense; an alternating current with a continuously changing current direction can be input to the coil 11 to generate a changing magnetic field and drive the rotating component 30 to reciprocate to repeatedly hit the limit part 135. Two or more vibration modules 100 can also be arranged in the vibration device 1, and the force sense combination of different vibration modules 100 can make the vibration device 1 generate a rotational force sense or a linear force sense with a stronger vibration sense.
[0055] The rotating component 30 is driven to rotate by the principles of electromagnetic induction and Lorentz force, and the coil 11 is arranged on the side of the rotating component 30; compared with the structural setting of using a motor to drive the eccentric weight to rotate, the structure of the vibration device 1 is more compact and relatively small in size, which can be applied to more usage environments, thereby improving the applicability of the vibration device 1.
[0056] Please refer to Figure 6 and Figure 7 In one embodiment of the present application, the stator assembly 10 includes two coils 11, the rotating assembly 30 is rotatably disposed between the two coils 11, and the current directions of the two coils 11 are the same.
[0057] In this embodiment, two coils 11 are arranged side by side in the stator component 10, and the two coils 11 are respectively located on both sides of the magnet 31. When the vibration device 1 is used, the current directions of the two coils 11 in the same vibration module 100 are the same. With this arrangement, since the relative positions of the magnet 31 and the two coils 11 are opposite, and the magnetic poles of the magnet 31 facing the two coils 11 are opposite, the directions of the magnetic field forces exerted on the magnet 31 by the magnetic fields generated by the two coils 11 are consistent, and the force acting on the magnet 31 is increased, so that the torque of the rotating component 30 is increased, and the rotation speed of the rotating component 30 is increased, thereby increasing the braking force when the rotating component 30 collides with the limit portion 135, thereby improving the vibration feeling.
[0058] Please refer to Figure 4 and Figure 7 In one embodiment of the present application, the rotating component 30 is provided with two magnets 31, the two magnets 31 are arranged side by side along the rotating direction of the rotating component 30, and the magnetization directions of the two magnets 31 are opposite;
[0059] The coil 11 has two conductive segments 111 connected in series and arranged side by side along the rotation direction of the rotating component 30 . When the rotating component 30 is centered, each conductive segment 111 corresponds to one of the magnets 31 .
[0060] In this embodiment, two magnets 31 are arranged side by side along the rotation direction in the rotating component 30, and the magnetization directions of the two magnets 31 are opposite. Specifically, taking the stator component 10 having two coils 11 as an example, the rotating component 30 is arranged between the two coils 11, and the N pole of one of the magnets 31 of the rotating component 30 faces one side of the coil 11, and the N pole of the other magnet 31 faces the other coil 11.
[0061] The coil 11 includes two conductive segments 111 spaced apart and arranged side by side along the rotation direction of the rotating component 30. At this time, the arrangement direction of the two conductive segments 111 is consistent with the arrangement direction of the two magnets 31. When the rotating component 30 is centered, each conductive segment 111 is arranged corresponding to a magnet 31. When the coil 11 is energized, since the current directions in the two conductive segments 111 are opposite, the magnetic flux lines of the generated magnetic field are opposite in direction, and since the magnetization directions of the two magnets 31 are opposite, the directions of the magnetic field forces received by the two magnets 31 are consistent, thereby increasing the magnetic field force received by the rotating component 30, increasing the rotation speed of the rotating component 30, and increasing the vibration force sense.
[0062] Combined with reference Figure 1 and Figure 2 In one embodiment of the present application, the stator assembly 10 includes a frame 13, the frame 13 includes a fixed portion 131 and a mounting portion 133 connected to each other, the coil 11 is arranged on the mounting portion 133, and the two side surfaces of the fixed portion 131 respectively form two limiting portions 135.
[0063] In this embodiment, the stator assembly 10 includes a frame 13 as a fixing base, the frame 13 includes a fixing portion 131 and a mounting portion 133 connected to the fixing portion 131, the fixing portion 131 has two side walls arranged at an angle, each side wall forms a stopper 135, and the mounting portion 133 is arranged between the two side walls and fixed with the coil 11. In this arrangement, the frame 13 is used to integrate the structures such as the stopper 135 and the coil 11 of the stator assembly 10 into an integral structure, and there is no need to separately set two independent stoppers 135, thereby reducing the use of components in the vibration module 100.
[0064] It can be understood that in some embodiments, two coils 11 are provided in the stator assembly 10, and two relatively arranged mounting portions 133 can be provided in the frame 13, and the two coils 11 can be fixed on the two mounting portions 133 respectively; and a rotation space 1331 can be formed between the two mounting portions 133, so that the rotating assembly 30 is limited between the two mounting portions 133, and the rotating assembly 30 is limited to avoid deviation of the rotating assembly 30 during rotation.
[0065] Please refer to Figure 2 In one embodiment of the present application, the mounting portion 133 is provided with a mounting opening 1333, and the coil 11 is mounted in the mounting opening 1333. In this way, the mounting opening 1333 can be used to limit the installation of the coil 11, thereby improving the position stability of the coil 11 fixed to the frame 13, and preventing the coil 11 from being deflected by the reaction force of the magnet 31 or other external forces, thereby improving the overall structural stability and performance stability of the vibration device 1.
[0066] Combined with reference Figure 1 and Figure 2 In one embodiment of the present application, the rotating assembly 30 includes a mass block 33 , the mass block 33 is rotatably connected to the stator assembly 10 , and the magnet 31 is disposed on the mass block 33 .
[0067] In this embodiment, a mass block 33 is provided on the rotating assembly 30, which can provide a mounting base for the magnet 31 and increase the weight of the rotating assembly 30, thereby increasing the vibration sensation when the vibration device 1 is running. The mass block 33 can be made of a heavy metal such as tungsten.
[0068] Combined with reference Figure 1 and Figure 2 In one embodiment of the present application, the mass block 33 includes a connecting portion 331 and a surrounding edge 333, the connecting portion 331 is arranged in the rotating space 1331 and is rotatably connected to the stator assembly 10, the magnet 31 is arranged on the connecting portion 331, the surrounding edge 333 is arranged on the edge of the connecting portion 331, and is located outside the rotating space 1331, and covers at least a portion of the edge of the stator assembly 10.
[0069] In this embodiment, the mass block 33 includes a connecting portion 331 and a surrounding edge 333. The surrounding edge 333 is arranged at the edge of the connecting portion 331, and the width of the surrounding edge 333 is greater than the thickness of the connecting portion 331, so that the surrounding edge 333 covers at least a portion of the outer edge of the stator assembly 10. Such an arrangement can not only protect the stator assembly 10, but also prevent foreign objects from entering between the coil 11 and the magnet 31 and affecting the rotation of the rotating assembly 30.
[0070] Please refer to Figure 2In one embodiment of the present application, the mass block 33 is provided with a limiting opening 3311, and the magnet 31 is arranged in the limiting opening 3311. With such a configuration, the limiting opening 3311 can be used to limit the magnet 31, thereby improving the position stability of the magnet 31 fixed on the mass block 33; so that the magnet 31 and the mass block 33 can move synchronously, thereby preventing the magnet 31 from being deflected on the mass block 33 due to the magnetic field force, thereby ensuring the stable performance of the vibration device 1. In addition, in the embodiment of the present application, when the stator component 10 is provided with the coil 11 only on one side of the rotating component 30, the limiting opening 3311 can be a groove structure formed on the surface of the mass block 33 facing the coil 11, or can penetrate the mass block 33 to embed the magnet 31. When the stator component 10 is provided with the coil 11 on both sides of the rotating component 30, the limiting opening 3311 penetrates the mass block 33 so that the magnet 31 and the coil 11 on either side are not blocked by the mass block 33, thereby preventing the magnetic field force on the magnet 31 from being reduced.
[0071] Please refer to Figure 6 In one embodiment of the present application, the stator assembly 10 further includes a magnetic conductive plate 15 , and the magnetic conductive plate 15 is disposed on a side of the coil 11 away from the rotating assembly 30 .
[0072] In this embodiment, at least one magnetic conductive plate 15 is further provided in the stator assembly 10. The magnetic conductive plate 15 is arranged on the side of the coil 11 away from the magnet 31. The magnetic conductive plate 15 can adjust the distribution of the magnetic field lines so that the magnetic field strength distribution in the rotating space 1331 is uniform. With such a configuration, the magnetic field force exerted on the rotating assembly 30 during rotation changes less, thereby improving the stability and smoothness of the rotation process. Compared with the structure in which a motor is used to drive the rotating assembly 30 to rotate, the vibration device 1 using the embodiment of the present application will not have a cogging effect, and the rotating assembly 30 will not be affected by the cogging force.
[0073] In some embodiments, the stator assembly 10 further includes a frame 13, the coil 11 and the magnetic conductive plate 15 are both fixed on the frame 13, a positioning hole 151 can be provided on the magnetic conductive plate 15, and a positioning portion 137 can be protruded on the surface of the frame 13 facing the magnetic conductive plate 15; or the positioning portion 137 can be protruded on the surface of the magnetic conductive plate 15 facing the frame 13, and a positioning hole 151 is provided on the frame 13, so that the positioning portion 137 is inserted into the positioning hole 151, thereby improving the connection strength of the magnetic conductive plate 15 fixed to the frame 13 and improving the overall structural stability of the stator assembly 10. In addition, in some embodiments, the rotating shaft 35 of the rotating assembly 30 can be inserted into the magnetic conductive plate 15 to realize the rotation connection between the rotating assembly 30 and the stator assembly 10.
[0074] Please refer to Figures 1 to 3In one embodiment of the present application, at least one of the two surfaces of the limiting portion 135 and the rotating assembly 30 that collide with each other is provided with a buffer 50. The buffer 50 may be a soft structure or an elastic structure such as foam, airbag, rubber, etc. The buffer 50 may be provided on the limiting portion 135, or on the rotating assembly 30, or on both the limiting portion 135 and the rotating assembly 30. With such a configuration, a rigid collision between the rotating assembly 30 and the limiting portion 135 can be avoided, and the buffer 50 can be used to buffer the impact force and protect the rotating assembly 30 and the stator assembly 10, thereby avoiding multiple impacts and collisions between the rotating assembly 30 and the limiting portion 135 and causing serious damage.
[0075] Please refer to Figures 3 to 5 In one embodiment of the present application, the stator assembly 10 is provided with two limit portions spaced apart along the rotation direction of the rotating assembly 30, and the rotating assembly 30 can reciprocate to the position of each limit portion 135 to collide with each limit portion 135 to generate a force sense.
[0076] In this embodiment, the limiting surfaces 1351 of the two limiting parts 135 provided in the stator assembly 10 can be oriented in different directions, so that when the rotating assembly 30 reciprocates to collide with the two limiting parts 135 respectively, the directions of the linear forces generated are different, which can meet more usage requirements and improve applicability.
[0077] Please refer to Figures 3 to 5 In one embodiment of the present application, the limiting portion 135 is provided with a limiting surface 1351 for colliding with the rotating assembly 30, and the limiting surfaces 1351 of the two limiting portions 135 are perpendicular to each other.
[0078] In this embodiment, the limiting surfaces 1351 of the two limiting parts 135 are arranged vertically so that the maximum rotation angle of the rotating component 30 is 90°. With such an arrangement, when at least two vibration devices 1 are combined, it is convenient to make the two vibration devices 1 generate force sensations in the same or opposite directions, thereby combining to obtain linear force sensations and rotational force sensations in the desired directions, which facilitates the control of the vibration device 1.
[0079] Please refer to Figure 8 and Fig. 9 In one embodiment of the present application, the vibration device 1 includes two vibration modules 100, and the two vibration modules 100 are axially symmetrically arranged. The two limiting surfaces 1351 of the vibration module 100 are respectively a first limiting surface 1353 and a second limiting surface 1355. The two first limiting surfaces 1353 are oriented in the same direction, and the two second limiting surfaces 1355 are opposite or back to back.
[0080] The rotational directions of the rotating components 30 of the two vibration modules 100 are opposite, and they can simultaneously hit the corresponding first limiting surface 1353 to generate a linear force feeling.
[0081] In this embodiment, two vibration modules 100 are arranged side by side in the vibration device 1, and two mutually perpendicular limiting surfaces 1351 in each vibration module 100 are defined as a first limiting surface 1353 and a second limiting surface 1355, respectively. When the two vibration modules 100 are arranged axially symmetrically, the first limiting surfaces 1353 of the two vibration modules 100 are oriented in the same direction, and the two second limiting surfaces 1355 are arranged opposite to or back to back; and the rotation directions of the rotating components 30 of the two vibration modules 100 are opposite. With such an arrangement, when the two rotating components 30 hit the corresponding first limiting surfaces 1353 at the same time, the centrifugal force in the two vibration modules 100 disappears, and the braking forces in the two vibration modules 100 are in opposite directions (upward and downward, respectively), so that the two braking forces cancel each other out, and the force sense in the normal direction of the second limiting surface 1355 is not felt or the force sense felt is smaller. Refer to Fig. 9 When the two rotating components 30 hit the corresponding second limiting surface 1355 at the same time, the braking forces have the same direction, and the external performance is reflected as the combined force of the two braking forces, generating a linear force sensation along the normal direction of the first limiting surface 1353. With the vibration device 1 of this embodiment, the orientation of the first limiting surface 1353 can be set according to actual needs, so as to generate a linear force sensation in the desired direction.
[0082] It can be understood that more than two vibration modules 100 can be arranged in the vibration device 1, so that at least two of the vibration modules 100 have a limiting surface 1351 facing the same direction. When a linear force sense is required in the normal direction of the limiting surface 1351, the rotating components 30 in at least some of the vibration modules 100 having the limiting surface 1351 facing the same direction are actuated to simultaneously impact the corresponding limiting surface 1351, thereby realizing a combination of multiple braking forces in the same direction and making the vibration device 1 produce a more obvious linear force sense, while other vibration modules 100 that do not have the limiting surface 1351 facing the same direction may not be actuated or two vibration modules 100 may be grouped together to offset the braking forces generated by each other.
[0083] Please refer to Fig.10 and Fig.11 In one embodiment of the present application, the vibration device 1 includes two vibration modules 100, and the two vibration modules 100 are centrally symmetrically arranged. The two limiting surfaces 1351 of the vibration module 100 are respectively a first limiting surface 1353 and a second limiting surface 1355, and the two first limiting surfaces 1353 are oriented in opposite directions, and the two second limiting surfaces 1355 are oriented in opposite directions.
[0084] The rotating components 30 of the two vibration modules 100 rotate in the same direction and can simultaneously impact the corresponding first limiting surface 1353 or the corresponding second limiting surface 1355 to generate a sense of rotational force.
[0085] In this embodiment, two vibration modules 100 are arranged in a centrally symmetrical manner in the vibration device 1, and two mutually perpendicular limiting surfaces 1351 in each vibration module 100 are defined as a first limiting surface 1353 and a second limiting surface 1355, respectively. At this time, the two first limiting surfaces 1353 are oriented in opposite directions, and the two second limiting surfaces 1355 are oriented in opposite directions. In addition, the rotation directions of the rotating components 30 of the two vibration modules 100 are made the same. In this arrangement, when the rotating components 30 of the two vibration modules 100 simultaneously hit the corresponding first limiting surface 1353 or the corresponding second limiting surface 1355, the braking forces in the two vibration modules 100 are in opposite directions and are located on different straight lines, so that the vibration device 1 can generate a sense of rotational force.
[0086] Understandable, see Fig.11 A plurality of vibration modules 100 may be provided in the vibration device 1, so that two of the vibration modules 100 form a group and the two vibration modules 100 are centrally symmetrically arranged. When it is necessary to make the vibration module 100 generate a sense of rotational force, the group of vibration modules 100 is operated in the above manner; the other vibration modules 100 may not be operated, or two vibration modules 100 may be formed into a group to offset the braking force generated by each other.
[0087] In some embodiments, the vibration device 1 includes at least two groups of vibration mechanisms arranged on different planes, and each group of vibration mechanisms includes four vibration modules 100 arranged in an array on a corresponding plane. It can be understood that in the embodiment of the present application, the vibration mechanism formed by the combination of four vibration modules 100 arranged in an array on the same plane can generate linear force senses in four directions on the plane and two rotational force senses in opposite directions by controlling the rotating components 30 of each vibration module 100 to rotate in different ways; and through the combination of at least two groups of vibration mechanisms, the vibration device 1 can have linear force senses in four directions and two rotational force senses on different planes, and can also achieve a combination of force senses in multiple directions. Further, three groups of vibration mechanisms can be set, respectively set on three planes perpendicular to each other, to achieve a combination of force senses in different directions in three-dimensional space.
[0088] The present application also proposes an electronic device, which includes a vibration device 1 as described in any of the above embodiments. The electronic device may be a handle, a mobile phone, a VR (Virtual Reality) device, an AR (Augmented Reality) device, etc. Since the electronic device proposed in the present application applies all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by all the above technical solutions, which will not be described one by one here.
[0089] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
