Abstract
Description
[Technical Field]
[0001] The present disclosure relates to the technical field of vibration devices, and more particularly to an exciter and an electronic device to which the exciter is applied. [Background technology]
[0002] Conventional vibration devices create the illusion of a force acting in a certain direction by constantly generating asymmetric vibrations, which are called anisotropic vibrations.
[0003] Currently, there are two methods for achieving this force sensation. One is to input an asymmetric signal into a linear resonator to create an illusion using human perception. This method can only generate a continuous, directional force sensation and cannot achieve discrete vibration output. At the same time, the equivalent force felt with this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to achieve a clear sense of direction. The other method generates a strong force sensation by rapidly braking the linear resonator. This method is characterized by the ability to generate highly asymmetric vibrations, a small proportion of extra vibrations, and a distinct, individual force sensation. However, this method requires independent vibration and braking units, and requires constant movement of the vibration unit and braking unit to switch between the energy storage state and the braking state. This makes high-speed continuous operation impossible and requires a complex device structure.
[0004] However, such a device only realizes vibration in a linear direction and is unable to generate a sense of force in a rotational direction. Summary of the Invention [Problem to be solved by the invention]

[0022] The exciter of the technical solution of the present disclosure forms a mounting cavity in a housing, and uses the mounting cavity to mount, fix, and protect two first rotating assemblies. The housing has a first side wall and a second side wall that are installed opposite each other. A first partition plate is installed in the mounting cavity of the housing, and both ends of the first partition plate are connected to the first side wall and the second side wall, respectively, and the mounting cavity is divided into a first cavity and a second cavity, so that the two first rotating assemblies can be mounted and fixed using the first cavity and the second cavity, respectively. That is, one first rotating assembly is installed in the first cavity, and another first rotating assembly is installed in the second cavity, and each first rotating assembly includes a first driving member and a first rotating part, whereby the first rotating part is connected to the output end of the first driving member and is installed eccentrically, so that two first By controlling the two first driving members to drive the rotating parts of the first and second side walls in rotation synchronously, the two first rotating parts can be simultaneously struck against the first and second side walls, respectively, or the two first rotating parts can simultaneously strike the first partition plate, thereby realizing the effect of two extreme positions. That is, when the two first rotating parts simultaneously strike the first and second side walls, respectively, a torque can be generated in the rotational direction, and the exciter can thereby generate a sense of force in the rotational direction, that is, a unidirectional rotational sense can be created. When the two first rotating parts simultaneously strike the first partition plate, equal but opposite forces are generated which cancel each other out. At the same time, by setting the first rotating assembly as the first driving member, it drives the rotating structure of the eccentrically installed first rotating part, which not only effectively simplifies the structure of the exciter, but also enables the exciter to achieve high-speed continuous operation and generate a strong and clear sense of force.

[0030] Conventional vibration devices create the illusion of a force acting in a certain direction by constantly generating asymmetric vibrations, which are called anisotropic vibrations.
[0031] Currently, there are two methods for achieving this force sensation. One is to input an asymmetric signal into a linear resonator to create an illusion using human perception. This method can only generate a continuous, directional force sensation and cannot achieve discrete vibration output. At the same time, the equivalent force felt with this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to achieve a clear sense of direction. The other method generates a strong force sensation by rapidly braking the linear resonator. This method is characterized by the ability to generate highly asymmetric vibrations, a small proportion of extra vibrations, and a distinct, individual force sensation. However, this method requires independent vibration and braking units, and requires constant movement of the vibration unit and braking unit to switch between the energy storage state and the braking state. This makes high-speed continuous operation impossible and requires a complex device structure.
[0032] However, such a device only realizes vibration in a linear direction and is unable to generate a sense of force in a rotational direction.
[0033] Based on the above ideas and problems, the present disclosure proposes an exciter 100. As can be understood, the exciter 100 is applied to electronic devices, which may be a tactile display, a tactile interface, a force feedback device, a vibrating feeder, a beauty product, a personal hygiene product, a personal entertainment product, a personal massage device, a tree harvester, an earthquake vibrator, etc. For example, but not limited to, a wireless controller for a game, a mobile motion controller for a sports game, a wireless steering wheel, a remote controller for a sports game on a game console, etc.
[0034] 1 to 6, in an embodiment of the present disclosure, the exciter 100 includes a housing 1 and two first rotating assemblies 2, the housing 1 has a mounting cavity 11 and a first side wall 12 and a second side wall 13 opposite to each other, the housing 1 further includes a first partition plate 14 connected to the first side wall 12 and the second side wall 13, the first partition plate 14 divides the mounting cavity 11 into a first cavity 111 and a second cavity 112, and one first rotating assembly 2 is connected to the first cavity 11. 1, and another first rotating assembly 2 is installed in the second cavity 112, each first rotating assembly 2 including a first driving member 21 and a first rotating part 22, the first rotating part 22 being connected to the output end of the first driving member 21 and being eccentrically installed, wherein the two first driving members 21 drive the two first rotating parts 22 in a synchronous rotational manner so that the two first rotating parts 22 simultaneously collide with the first partition plate 14 or simultaneously collide with the first side wall 12 and the second side wall 13, respectively.
[0035] In this embodiment, the housing 1 of the exciter 100 is used to mount, fix, and protect components such as the two first rotating assemblies 2, i.e., the housing 1 provides a mounting structure for components such as the two first rotating assemblies 2. As can be understood, the housing 1 may be a structure such as a mounting shell, a mounting box, a case body, etc., and is not limited thereto. The housing 1 has a mounting cavity 11 for arranging and mounting components such as the two first rotating assemblies 2, and the mounting cavity 11 may be a sealed cavity, or of course, the mounting cavity 11 may be an open cavity.
[0036] As can be understood, the housing 1 may have a unitary structure or a divided structure. To facilitate the attachment and detachment of components such as the two first rotating assemblies 2, the housing 1 may be selectively installed as separate bodies. That is, the housing 1 includes a first housing and a second housing, which are butt-connected to each other and surround and form the mounting cavity 11. The housing 1 may have a regular shape such as a circle, ellipse, square, triangle, or other polygon, or may have other irregular shapes, and the shapes are not limited thereto.
[0037] In this embodiment, in order to generate a rotational force sensation in the exciter 100, the housing 1 has a first side wall 12 and a second side wall 13 installed opposite each other. The first side wall 12 and the second side wall 13 may be outer walls of the housing 1, or may be side walls or partition plate structures installed in the mounting cavity 11 of the housing 1, and are not limited thereto. A first partition plate 14 is installed in the mounting cavity 11 of the housing 1, and both ends of the first partition plate 14 are connected to the first side wall 12 and the second side wall 13, respectively, and the mounting cavity 11 is divided into a first cavity 111 and a second cavity 112. One first rotating assembly 2 is mounted and fixed using the first cavity 111, and another first rotating assembly 2 is mounted and fixed using the second cavity 112.
[0038] Alternatively, the housing 1 may be installed in a square shape. Alternatively, the housing 1 may have a square or rectangular structure. In this embodiment, the first rotating assembly 2 includes a first driving member 21 and a first rotating portion 22. The first driving member 21 is installed in the first cavity 111 / second cavity 112. The first driving member 21 may be directly fixed to the inner wall of the housing 1 or may be attached to the first cavity 111 / second cavity 112 by other structures such as a bracket or a mounting seat.
[0039] In this embodiment, the first rotating part 22 is connected to the output end of the first driving member 21 and is installed eccentrically. As can be understood, the first rotating part 22 may have an eccentric structure, and when one end of the first rotating part 22 is connected to the output end of the first driving member 21 and the first driving member 21 thereby drives the first rotating part 22 to rotate, the first rotating part 22 moves circumferentially around the output end of the first driving member 21, i.e., the position where the first rotating part 22 is connected to the output end of the first driving member 21 may be located at an eccentric position of the structure of the first rotating part 22 itself (the position where the first rotating part 22 is connected to the output end of the first driving member 21 does not overlap with the center of the first rotating part 22).
[0040] As can be seen, by controlling the two first driving members 21 to drive the two first rotating parts 22 in rotational synchronization, the two first rotating parts 22 can simultaneously collide with the first side wall 12 and the second side wall 13, respectively, or the two first rotating parts 22 can simultaneously collide with the first partition plate 14, thereby realizing the effects of two extreme positions, that is, when the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, a torque can be generated in the rotational direction, thereby enabling the exciter 100 to generate a sense of force in the rotational direction, that is, to create a unidirectional rotational tactile sensation; and when the two first rotating parts 22 simultaneously collide with the first partition plate 14, equal but opposite forces are generated which cancel each other out, thereby ensuring that the exciter 100 can generate a unidirectional rotational force sensation.
[0041] At the same time, by setting the first rotating assembly 2 as the first driving member 21 and driving the rotating structure of the eccentrically installed first rotating part 22, not only is the structure of the exciter 100 effectively simplified, but the exciter 100 can also achieve high-speed continuous operation and generate a powerful and clear sense of force.
[0042] It should be noted that the exciter 100 further includes a controller or control structure, which can control the two first drive members 21 to rotationally drive the two first rotating parts 22. As can be understood, the controller or control structure may be a separate controller or remote control, or may be a structure such as a control circuit or control button integrated in the exciter 100, and is not limited thereto.
[0043] In this embodiment, as shown in Fig. 3, the two first driving members 21 are controlled to rotate in the forward direction and the two first rotating parts 22 are driven to rotate clockwise so that the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, thereby generating a torque in the clockwise direction, and the exciter 100 is thereby able to generate a sense of force in the clockwise rotation direction. As shown in Fig. 4, the two first driving members 21 are controlled to rotate in the reverse direction and the two first rotating parts 22 are driven to rotate counterclockwise so that the two first rotating parts 22 simultaneously collide with the first partition plate 14, thereby generating equal but opposite forces in the counterclockwise direction that cancel each other out, and the exciter 100 is thereby able to generate a sense of force in one direction, the clockwise rotation direction.
[0044] As can be understood, if the exciter 100 is defined as having a first state in which it rotates clockwise, then in the first state, the exciter 100 is defined as having a first position in which the two first driving members 21 are controlled to rotate forward and the two first rotating parts 22 are driven to rotate clockwise so that the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, and a second position in which the two first driving members 21 are controlled to rotate backward and the two first rotating parts 22 are driven to rotate counterclockwise so that the two first rotating parts 22 simultaneously collide with the first partition plate 14. As shown in FIG. 7 , when two acceleration sensors are used to detect vibration of the exciter 100, at the first position in the first state, there is a clear vibration sensation in the housing 1 of the exciter 100 and a clockwise rotation sensation, and at the second position in the first state, there is a vibration sensation in the housing 1 of the exciter 100. Because the force arm in the second position is shorter than the force arm in the first position, the vibration sensation is relatively low.
[0045] The exciter 100 of the present disclosure has a mounting cavity 11 formed in a housing 1, and uses the mounting cavity 11 to mount, fix, and protect two first rotating assemblies 2. The housing has a first side wall 12 and a second side wall 13 that are installed opposite each other. A first partition plate 14 is installed in the mounting cavity 11 of the housing 1, and both ends of the first partition plate 14 are connected to the first side wall 12 and the second side wall 13, respectively, and the mounting cavity 11 is divided into a first cavity 111 and a second cavity 112. , whereby two first rotating assemblies 2 can be mounted and fixed using the first cavity 111 and the second cavity 112, respectively, i.e., one first rotating assembly 2 is installed in the first cavity 111, and another first rotating assembly 2 is installed in the second cavity 112, and each first rotating assembly 2 includes a first driving member 21 and a first rotating part 22, whereby the first rotating part 22 is connected to the output end of the first driving member 21 and is installed eccentrically, whereby By controlling the two first driving members 21 to drive the two first rotating parts 22 in rotation synchronization, the effect of two extreme positions can be realized, such that the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, or the two first rotating parts 22 simultaneously collide with the first partition plate 14. That is, when the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, a torque can be generated in the rotation direction, and the exciter 100 can rotate in the rotation direction. The two first rotating parts 22 collide with the first partition plate 14 at the same time, generating forces of equal magnitude but in opposite directions that cancel each other out. At the same time, the first rotating assembly 2 is set as the first driving member 21 to drive the rotating structure of the first rotating part 22, which is eccentrically installed. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a strong and clear force.
[0046] In this embodiment, as shown in Figures 1 to 6, each first driving member 21 is a rotor motor in which a rotating shaft 211 is installed, and an axial hole 221 is installed in each first rotating part 22, the axial hole 221 is installed eccentrically on the first rotating part 22, and the rotating shaft 211 is drilled within the axial hole 221.
[0047] As can be understood, the structure of the first rotating part 22 may be a regular shape or an irregular shape. Optionally, the shape of the first rotating part 22 may be a circle, an ellipse, a rectangle, a triangle, or a polygon. The shaft hole 221 does not overlap with the shape center of the first rotating part 22. Of course, the shape of the first rotating part 22 may be an irregular shape and is not limited here.
[0048] In this embodiment, the first driving member 21 is configured as a rotor motor, and the rotor motor is used to drive the rotating structure of the first rotating part 22, which is eccentrically installed. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a strong and clear sense of force.
[0049] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in one rotation direction. The first rotating assembly 2 in the first cavity 111 and the first rotating assembly 2 in the second cavity 112 are installed symmetrically about the center. Optionally, the weights of the two first rotating parts 22 are the same. The shape contours of the two first rotating parts 22 are the same.
[0050] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in one rotational direction. The driving frequencies of the two first driving members 21 are the same. The driving voltages of the two first driving members 21 are the same.
[0051] In one embodiment, each first rotating part 22 includes at least one mass block 222. As can be understood, the material of the mass block 222 can be a metallic material, i.e., the mass block 222 is made of a metallic material. Of course, the mass block 222 can also be a non-metallic material, i.e., the mass block 222 is made of a non-metallic material.
[0052] In order to generate a strong and clear force in the exciter 100, the mass block 222 of the first rotating part 22 is made of a relatively heavy structure, and optionally, the mass block 222 is made of a metal material. To further increase the mass of the first rotating part 22, the first rotating part 22 can have a counterweight or multiple mass blocks 222 installed on the mass block 222, where the counterweight or multiple mass blocks 222 are located radially or circumferentially around the rotation center of the first rotating part 22, and the axial hole 221 is located at an eccentric position of the entire first rotating part 22 (i.e., the axial hole 221 does not overlap with the center of the entire first rotating part 22).
[0053] 1 to 6, the number of mass blocks 222 of the first rotating part 22 may be one, two, three, four, or more, and is not limited thereto. Among the multiple mass blocks 222, the shaft hole 221 on the mass block 222 connected to the rotation shaft 211 of the first driving member 21 is located at an eccentric position of the mass block 222, and in this case, another mass block 222 is connected to the mass block 222 in the radial or circumferential direction, and the distance from the other mass block 222 to the shaft hole 221 is greater than the distance from the other mass block 222 to the center of the mass block 222.
[0054] Of course, the axial hole 221 may be located at the center of the mass block 222, in which case another mass block 222 is connected to one side of the mass block 222, so that the entire first rotating part 22 has an eccentric structure, which is not limited here.
[0055] Alternatively, each first rotating part 22 may include three mass blocks 222, one mass block 222 connected to the output end of the first driving member 21 and eccentrically installed, and the other two mass blocks 222 connected sequentially and arranged along the radial direction of the first rotating part 22, or the other two mass blocks 222 connected sequentially and arranged along the circumferential direction of the mass blocks 222.
[0056] In one embodiment, the first partition plate 14 is installed perpendicular to the first side wall 12, the first partition plate 14 is installed perpendicular to the second side wall 13, and the first partition plate 14 extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13. As can be understood, as shown in FIGS. 3 to 6 , the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed parallel to each other. The first cavity 111 and the second cavity 112 of the housing 1 are installed symmetrically with respect to the first partition plate 14. At the same time, to achieve clockwise or counterclockwise rotation of the two first rotating parts 22 of the two first rotating assemblies 2 in the first cavity 111 and the first rotating assembly 2 in the second cavity 112 are installed centrally symmetrically.
[0057] Alternatively, as shown in Figures 3 to 6, one first driving member 21 is installed adjacent to the connection point between the first side wall 12 and the first partition plate 14, and another first driving member 21 is installed adjacent to the connection point between the second side wall 13 and the first partition plate 14, thereby placing the two first driving members 21 symmetrically about the center.
[0058] Of course, in other embodiments, the first partition plate 14 does not have to be perpendicular to the first side wall 12, and the first partition plate 14 does not have to be perpendicular to the second side wall 13. For example, when the first rotating unit 22 is installed in a fan shape, when the first driving member 21 rotates the first rotating unit 22 by 90° to collide with the first side wall 12 / second side wall 13 or the first partition plate 14, the first partition plate 14 and the first side wall 12 do not have to be perpendicular, and the first partition plate 14 and the second side wall 13 do not have to be perpendicular, and this is not limited here. As can be understood, the first side wall 12 / second side wall 13 may be configured as a two-tier structure installed at an angle, in which case the first partition plate 14 is connected to the angle formed by the first side wall 12 / second side wall 13, in which case the first partition plate 14 is not installed perpendicular to at least one portion of the first side wall 12 / second side wall 13, and this is not limited here.
[0059] In one embodiment, when it is defined that two first rotating parts 22 collide with the first side wall 12 and the second side wall 13 simultaneously, the two first rotating parts 22 form a first impact point 121 and a second impact point 131 on the first side wall 12 and the second side wall 13, respectively, and the distance from the first impact point 121 to the first partition plate 14 is the same as the distance from the second impact point 131 to the first partition plate 14.
[0060] In this embodiment, as shown in Figure 3, in order to ensure that the distances from the first impact point 121 and the second impact point 131 formed when the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, to the first partition plate 14 are the same, the exciter 100 aligns the sense of force generated in the clockwise rotation direction, and improves the user's experience, the output end of one first driving member 21 (i.e., the rotation center of the first rotating part 22) is located on the isotropic line of the angle formed by the first side wall 12 and the first partition plate 14, and the output end of another first driving member 21 (i.e., the rotation center of the first rotating part 22) is located on the isotropic line of the angle formed by the second side wall 13 and the first partition plate 14.
[0061] In one embodiment, the angle by which each first driving member 21 rotates the first rotating unit 22 is selectively 90°. When the two first driving members 21 are defined as driving the two first rotating units 22 to rotate forward, the two first rotating units 22 collide with the first side wall 12 and the second side wall 13 simultaneously, and when the two first driving members 21 are defined as driving the two first rotating units 22 to rotate backward, the two first rotating units 22 collide with the first partition plate 14 simultaneously.
[0062] In this embodiment, as shown in Figures 1 and 3 to 6, the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed parallel to each other. A first partition plate 14 is perpendicular to the first side wall 12 and the second side wall 13 and extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13. One first drive member 21 is installed near the connection point between the first side wall 12 and the first partition plate 14, and another first drive member 21 is installed near the connection point between the second side wall 13 and the first partition plate 14. Selectively, one first drive member 21 is located diagonally across the angle between the first side wall 12 and the first partition plate 14, and the other first drive member 21 is located diagonally across the angle between the second side wall 13 and the first partition plate 14.
[0063] As can be understood, the first rotating part 22 is located on the opposite side of the angle between the first side wall 12 and the first partition plate 14 of the first driving member 21, or on one side of the angle between the second side wall 13 and the first partition plate 14, so that when the first driving member 21 drives the first rotating part 22 to rotate by 90 degrees, the first rotating part 22 collides with the first side wall 12 or the second side wall 13.
[0064] Of course, the angle by which each first driving member 21 rotates the first rotating unit 22 may be greater than or less than 90°. Note that, when the connecting line between the rotation axis 211 of the first driving member 21 and the center of the first rotating unit 22 is not parallel to the first side wall 12 / second side wall 13 or the first partition plate 14, the angle by which the first driving member 21 rotates the first rotating unit 22 may be greater than or less than 90°. That is, when two first rotating parts 22 collide with the first side wall 12 and the second side wall 13 at the same time, respectively, the connecting line between the rotation axis 211 of the first driving member 21 and the center of the first rotating part 22 is not parallel to the first side wall 12 / second side wall 13, and when two first rotating parts 22 collide with the first partition plate 14 at the same time, the connecting line between the rotation axis 211 of the first driving member 21 and the center of the first rotating part 22 is not parallel to the first partition plate 14. In this case, the angle by which the first driving member 21 rotates the first rotating part 22 may be greater than 90° or less than 90°, and is not limited here.
[0065] In this embodiment, as shown in Fig. 3, when the two first driving members 21 drive the two first rotating parts 22 in the forward direction, i.e., the two first driving members 21 are defined as rotating in the forward direction, and when the two first driving members 21 simultaneously drive the two first rotating parts 22 in the clockwise direction, the two first rotating parts 22 simultaneously collide with the first side wall 12 and the second side wall 13. As shown in Fig. 4, when the two first driving members 21 drive the two first rotating parts 22 in the reverse direction, i.e., the two first driving members 21 are defined as rotating in the reverse direction, and when the two first driving members 21 simultaneously drive the two first rotating parts 22 in the counterclockwise direction, the two first rotating parts 22 simultaneously collide with the first partition plate 14.
[0066] In one embodiment, when the first rotating part 22 is defined as colliding with the first side wall 12, the second side wall 13 or the first partition plate 14, a first collision point is formed on the first side wall 12, the second side wall 13 or the first partition plate 14, respectively, and each first rotating assembly 2 further includes a first buffer part 23, which is installed on the first side wall 12 and / or the second side wall 13 and / or the first partition plate 14 and is located at the first collision point, or when the first buffer part 23 is installed on the first rotating part 22 and the first drive member 21 drives the first rotating part 22 to rotate, the first buffer part 23 abuts against the first collision point.
[0067] In this embodiment, as shown in FIGS. 1 to 6, by installing the first buffer portion 23, the impact force of the first rotating portion 22 can be adjusted and buffered using the first buffer portion 23, and the sensitive frequency of the vibration wave can be adjusted using the first buffer portion 23, thereby making the tip of the peak in FIG. 7 sharper, and the first buffer portion 23 also has a noise reduction effect.
[0068] As can be understood, when the first rotating portion 22 collides with the first side wall 12 / second side wall 13, the first rotating portion 22 forms a first impact point 121 / second impact point 131 on the first side wall 12 / second side wall 13, and the first impact point 121 / second impact point 131 overlaps with the first collision point.
[0069] In this embodiment, the first buffer portion 23 may be installed on the first side wall 12 and / or the second side wall 13 and / or the first partition plate 14 of the housing 1, and may be located at the first collision point. Of course, the first buffer portion 23 may be installed on the first rotating portion 22, so that when the first driving member 21 rotates the first rotating portion 22, the first buffer portion 23 abuts against the first collision point.
[0070] In this embodiment, the first buffer section 23 includes a plurality of first buffer sections 23, and the plurality of first buffer sections 23 are respectively installed on the first side wall 12, the second side wall 13, and the first partition plate 14. Alternatively, the plurality of first buffer sections 23 are installed on opposite sides of the first rotating section 22, so that when the first rotating section 22 collides with the first side wall 12 / second side wall 13, the first side wall 12 / second side wall 13 abuts against the first buffer sections 23, or when the first rotating section 22 collides with the first partition plate 14, the first partition plate 14 abuts against the first buffer sections 23, etc., are not limited here.
[0071] Alternatively, the first buffer portion 23 may be made of a compressible material such as foam, sponge, rubber mat, etc., but is not limited thereto. That is, the first buffer portion 23 does not use a rigid material.
[0072] In this embodiment, the first driving member 21 is fixedly mounted in the first cavity 111 / second cavity 112 of the mounting cavity 11, and the multiple mass blocks 222 of the first rotating part 22 are combined together without changing their relative positions, and the entire multiple mass blocks 222 are eccentric mass blocks that move synchronously.
[0073] In one embodiment, the exciter 100 further includes two second rotating assemblies 3, one second rotating assembly 3 installed in the first cavity 111 and spaced apart from the first rotating assembly 2, and another second rotating assembly 3 installed in the second cavity 112 and spaced apart from the first rotating assembly 2, each second rotating assembly 3 including a second driving member 31 and a second rotating part 32, the second rotating part 32 connected to the output end of the second driving member 31 and eccentrically installed, wherein the two second driving members 31 drive the two second rotating parts 32 to rotate synchronously so that the two second rotating parts 32 simultaneously collide with the first partition plate 14 or simultaneously collide with the first side wall 12 and the second side wall 13, respectively.
[0074] In this embodiment, the second rotating assembly 3 is installed in the first cavity 111 and the second cavity 112 of the mounting cavity 11 of the housing 1, respectively, and the second rotating assembly 3 is installed at a distance from the first rotating assembly 2. The second rotating assembly 3 is configured as a second driving member 31 and a second rotating unit 32. The second rotating unit 32 is connected to the output end of the second driving member 31 and is installed eccentrically. Therefore, the two second driving members 31 are controlled to drive the two second rotating units 32 in rotation synchronously. When the two second rotating parts 32 collide with the first side wall 12 and the second side wall 13 at the same time, or when the two second rotating parts 32 collide with the first partition plate 14 at the same time, the effect of two extreme positions can be realized. That is, when the two second rotating parts 32 collide with the first side wall 12 and the second side wall 13 at the same time, a torque can be generated in the rotational direction, thereby allowing the exciter 100 to generate a sense of force in the rotational direction, creating a unidirectional rotational sensation. When the two second rotating parts 32 collide with the first partition plate 14 at the same time, equal but opposite forces are generated, which cancel each other out.
[0075] As can be seen, by configuring the second rotating assembly 3 as the second driving member 31 and driving the rotating structure of the eccentrically installed second rotating part 32, not only can the structure of the exciter 100 be effectively simplified, but the exciter 100 can also achieve high-speed continuous operation and generate a powerful and clear sense of force.
[0076] In one embodiment, the exciter 100 is defined as having a first state in which it rotates clockwise and a second state in which it rotates counterclockwise, and in the first state, two first driving members 21 drive two first rotating parts 22 in rotational synchronization, and in the second state, two second driving members 31 drive two second rotating parts 32 in rotational synchronization.
[0077] As can be seen, in a first state in which the exciter 100 rotates clockwise, the controller or control structure controls only the two first drive members 21 of the two first rotating assemblies 2 to rotationally drive the two first rotating parts 22, and in this case the two second drive members 31 of the two second rotating assemblies 3 are in a power outage state. In a second state in which the exciter 100 rotates counterclockwise, the controller or control structure controls only the two second drive members 31 of the two second rotating assemblies 3 to rotationally drive the two second rotating parts 32, and in this case the two first drive members 21 of the two first rotating assemblies 2 are in a power outage state.
[0078] In this embodiment, in order to ensure that the controller or control structure controls the two first rotating assemblies 2 or the two second rotating assemblies 3 to achieve synchronous operation, in the initial state, the two first rotating assemblies 2 are installed centrally symmetrically in the first cavity 111 and the second cavity 112, and the two second rotating assemblies 3 are installed centrally symmetrically in the first cavity 111 and the second cavity 112.
[0079] In this embodiment, as shown in FIG. 5, the two second driving members 31 are controlled to rotate in the forward direction, and the two second rotating parts 32 are driven to rotate counterclockwise so that the two second rotating parts 32 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, thereby generating a torque in the counterclockwise direction, and the exciter 100 can thereby generate a force sensation in the counterclockwise rotation direction. As shown in FIG. 6, the two second driving members 31 are controlled to rotate in the reverse direction, and the two second rotating parts 32 are driven to rotate clockwise so that the two second rotating parts 32 simultaneously collide with the first partition plate 14, thereby generating an equal but opposite force in the clockwise direction, which cancels out, and the exciter 100 can thereby generate a force sensation in one direction, the counterclockwise rotation direction.
[0080] As can be understood, the exciter 100 is defined to have a second state in which it rotates counterclockwise, and in the second state, the exciter 100 is defined to have a first position in which the two second driving members 31 are controlled to rotate forward and the two second rotating parts 32 are driven to rotate counterclockwise so that the two second rotating parts 32 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, and a second position in which the two second driving members 31 are controlled to rotate backward and the two second rotating parts 32 are driven to rotate clockwise so that the two second rotating parts 32 simultaneously collide with the first partition plate 14.
[0081] Optionally, the structure of the first rotating assembly 2 is the same as that of the second rotating assembly 3. In this embodiment, as shown in Figures 1 to 6, each second driving member 31 is a rotor motor in which a rotating shaft 211 is installed, and each second rotating part 32 has a shaft hole 221, which is eccentrically installed on the second rotating part 32, and the rotating shaft 211 is drilled in the shaft hole 221.
[0082] As can be understood, the structure of the second rotating part 32 may be a regular shape or an irregular shape. Optionally, the shape of the second rotating part 32 may be a circle, an ellipse, a rectangle, a triangle, or a polygon. The shaft hole 221 does not overlap with the shape center of the second rotating part 32. Of course, the shape of the second rotating part 32 may be an irregular shape and is not limited here.
[0083] In this embodiment, the second driving member 31 is configured as a rotor motor, and the rotor motor is used to drive the rotation structure of the second rotating part 32, which is installed eccentrically. This not only effectively simplifies the structure of the exciter 100, but also enables the exciter 100 to achieve high-speed continuous operation and generate a strong and clear sense of force.
[0084] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in one rotation direction. The second rotating assembly 3 in the first cavity 111 and the second rotating assembly 3 in the second cavity 112 are installed symmetrically about the center. Optionally, the weights of the two second rotating parts 32 are the same. The shape contours of the two second rotating parts 32 are the same.
[0085] As can be seen, the exciter 100 further ensures that a strong and clear force is generated in one rotational direction. The driving frequencies of the two second driving members 31 are the same. The driving voltages of the two second driving members 31 are the same.
[0086] In one embodiment, each second rotating portion 32 includes at least one mass block 222. As can be appreciated, the material of the mass block 222 can be a metallic material, i.e., the mass block 222 is made of a metallic material. Of course, the mass block 222 can also be a non-metallic material, i.e., the mass block 222 is made of a non-metallic material.
[0087] In order to generate a strong and clear force in the exciter 100, the mass block 222 of the second rotating part 32 is made of a relatively heavy structure, and optionally, the mass block 222 is made of a metal material. To further increase the mass of the second rotating part 32, the second rotating part 32 can have a counterweight or multiple mass blocks 222 installed on the mass block 222, where the counterweight or multiple mass blocks 222 are located radially or circumferentially around the rotation center of the second rotating part 32, and the axial hole 221 is located at an eccentric position of the entire second rotating part 32 (i.e., the axial hole 221 does not overlap with the center of the entire second rotating part 32).
[0088] 1 to 6, the number of mass blocks 222 of the second rotating part 32 may be one, two, three, four, or more, and is not limited thereto. Among the multiple mass blocks 222, the shaft hole 221 on the mass block 222 connected to the rotation shaft 211 of the second driving member 31 is located at an eccentric position of the mass block 222, and in this case, another mass block 222 is connected to the mass block 222 in the radial or circumferential direction, and the distance from the other mass block 222 to the shaft hole 221 is greater than the distance from the other mass block 222 to the center of the mass block 222.
[0089] Of course, the axial hole 221 may be located at the center of the mass block 222, in which case another mass block 222 is connected to one side of the mass block 222, so that the entire second rotating part 32 has an eccentric structure, which is not limited here.
[0090] Alternatively, each second rotating part 32 may include three mass blocks 222, one mass block 222 connected to the output end of the second driving member 31 and eccentrically installed, and the other two mass blocks 222 connected and arranged sequentially along the radial direction of the second rotating part 3, or the other two mass blocks 222 connected and arranged sequentially along the circumferential direction of the mass blocks 222.
[0091] In one embodiment, as shown in Figures 3 to 6, the first partition plate 14 is installed perpendicular to the first side wall 12, the first partition plate 14 is installed perpendicular to the second side wall 13, and the first partition plate 14 extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13.
[0092] As can be seen, as shown in Figures 3 to 6, the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed parallel to each other. The first cavity 111 and the second cavity 112 of the housing 1 are installed symmetrically with respect to the first partition plate 14. At the same time, in order to realize that the two second rotating parts 32 of the two second rotating assemblies 3 rotate in the same direction, clockwise or counterclockwise, the second rotating assemblies 3 in the first cavity 111 and the second rotating assemblies 3 in the second cavity 112 are installed symmetrically with respect to the center.
[0093] Alternatively, as shown in Figures 3 to 6, one second driving member 31 is installed adjacent to the connection point between the first side wall 12 and the first partition plate 14, and another second driving member 31 is installed adjacent to the connection point between the second side wall 13 and the first partition plate 14, thereby placing the two second driving members 31 symmetrically about the center.
[0094] Alternatively, the first drive member 21 and the second drive member 31 located in the first cavity 111 are arranged symmetrically with respect to the perpendicular bisector of the first partition plate 14. The first drive member 21 and the second drive member 31 located in the second cavity 112 are arranged symmetrically with respect to the perpendicular bisector of the first partition plate 14.
[0095] In one embodiment, when it is defined that two second rotating portions 32 collide with the first side wall 12 and the second side wall 13 simultaneously, the two second rotating portions 32 form a third impact point 122 and a fourth impact point 132 on the first side wall 12 and the second side wall 13, respectively, and the distance from the third impact point 122 to the first partition plate 14 is the same as the distance from the fourth impact point 132 to the first partition plate 14.
[0096] In this embodiment, as shown in Figure 5, in order to ensure that the distances from the third impact point 122 and the fourth impact point 132 formed when the two second rotating parts 32 simultaneously collide with the first side wall 12 and the second side wall 13, respectively, to the first partition plate 14 are the same, the exciter 100 aligns the sense of force generated in the counterclockwise rotation direction, and improves the user's experience, the output end of one second driving member 31 (i.e., the rotation center of the second rotating part 32) is located on the isotropic line of the angle formed by the first side wall 12 and the first partition plate 14, and the output end of another second driving member 31 (i.e., the rotation center of the second rotating part 32) is located on the isotropic line of the angle formed by the second side wall 13 and the first partition plate 14.
[0097] In one embodiment, as shown in Figures 3 to 6, when the first rotating part 22 is defined as colliding with the first side wall 12, the first rotating part 22 forms a first collision point on the first side wall 12, and when the second rotating part 32 is defined as colliding with the first side wall 12, the second rotating part 32 forms a second collision point on the first side wall 12, and the distance from the first collision point to the first partition plate 14 is the same as the distance from the second collision point to the first partition plate 14.
[0098] As can be seen, the shape profile of the first rotating part 22 and the shape profile of the second rotating part 32 are the same, i.e. the structure of the first rotating assembly 2 and the structure of the second rotating assembly 3 are the same.
[0099] In one embodiment, the angle by which each second driving member 31 rotates the second rotating unit 32 is 90°. When it is defined that the two second driving members 31 rotate the two second rotating units 32 in the forward direction, the two second rotating units 32 collide with the first side wall 12 and the second side wall 13 simultaneously, and when it is defined that the two second driving members 31 rotate the two second rotating units 32 in the reverse direction, the two second rotating units 32 collide with the first partition plate 14 simultaneously.
[0100] In this embodiment, as shown in Figures 1 and 3 to 6, the first side wall 12 and the second side wall 13 of the housing 1 are selectively installed parallel to each other. A first partition plate 14 is perpendicular to the first side wall 12 and the second side wall 13 and extends connecting the midpoint of the first side wall 12 and the midpoint of the second side wall 13. One second drive member 31 is installed adjacent to the connection point between the first side wall 12 and the first partition plate 14, and another second drive member 31 is installed adjacent to the connection point between the second side wall 13 and the first partition plate 14. Selectively, one second drive member 31 is located diagonally across the angle between the first side wall 12 and the first partition plate 14, and the other second drive member 31 is located diagonally across the angle between the second side wall 13 and the first partition plate 14.
[0101] As can be understood, the second rotating part 32 is located on the opposite side of the angle between the first side wall 12 and the first partition plate 14 of the second driving member 31, or on one side of the angle between the second side wall 13 and the first partition plate 14, so that when the second driving member 31 drives the second rotating part 32 to rotate by 90 degrees, the second rotating part 32 collides with the first side wall 12 or the second side wall 13.
[0102] Of course, the angle by which each second driving member 31 rotationally drives the second rotating unit 32 may be greater than or less than 90°. Note that, when the connecting line between the rotation axis 211 of the second driving member 31 and the center of the second rotating unit 32 is not parallel to the first side wall 12 / second side wall 13 or the first partition plate 14, the angle by which the second driving member 31 rotationally drives the second rotating unit 32 may be greater than or less than 90°. That is, when two second rotating parts 32 collide with the first side wall 12 and the second side wall 13 at the same time, respectively, the connecting line between the rotation axis 211 of the second driving member 31 and the center of the second rotating part 32 is not parallel to the first side wall 12 / second side wall 13, and when two second rotating parts 32 collide with the first partition plate 14 at the same time, the connecting line between the rotation axis 211 of the second driving member 31 and the center of the second rotating part 32 is not parallel to the first partition plate 14. In this case, the angle by which the second driving member 31 rotates the second rotating part 32 may be greater than 90° or less than 90°, and is not limited here.
[0103] In this embodiment, as shown in Fig. 5, the two second driving members 31 are defined as driving the two second rotating parts 32 to rotate in the forward direction, i.e., when the two second driving members 31 rotate in the forward direction and thereby simultaneously drive the two second rotating parts 32 to rotate counterclockwise, the two second rotating parts 32 simultaneously collide with the first side wall 12 and the second side wall 13. As shown in Fig. 6, the two second driving members 31 are defined as driving the two second rotating parts 32 to rotate in the reverse direction, i.e., when the two second driving members 31 rotate in the reverse direction and thereby simultaneously drive the two second rotating parts 32 to rotate clockwise, the two second rotating parts 32 simultaneously collide with the first partition plate 14.
[0104] In one embodiment, when the second rotating part 32 is defined as colliding with the first side wall 12, the second side wall 13 or the first partition plate 14, a second collision point is formed on each of the first side wall 12, the second side wall 13 or the first partition plate 14, and each second rotating assembly 3 further includes a second buffer part 33, which is installed on the first side wall 12 and / or the second side wall 13 and / or the first partition plate 14 and is located at the second collision point, or when the second buffer part 33 is installed on the second rotating part 32 and the second drive member 31 drives the second rotating part 32 to rotate, the second buffer part 33 abuts against the second collision point.
[0105] In this embodiment, as shown in FIGS. 1 to 6, by installing the second buffer portion 33, the impact force of the second rotating portion 32 can be adjusted and buffered using the second buffer portion 33, and the sensitive frequency of the vibration wave can be adjusted using the second buffer portion 33, thereby making the tip of the peak in FIG. 7 sharper, and the second buffer portion 33 also has a noise reduction effect.
[0106] As can be seen, when the second rotating portion 32 collides with the first side wall 12 / second side wall 13, the second rotating portion 32 forms a third impact point 122 / fourth impact point 132 on the first side wall 12 / second side wall 13, and the third impact point 122 / fourth impact point 132 overlaps with the second collision point.
[0107] In this embodiment, the second buffer portion 33 may be installed on the first side wall 12 and / or the second side wall 13 and / or the first partition plate 14 of the housing 1, and may be located at the first collision point. Of course, the second buffer portion 33 may also be installed on the second rotating portion 32, so that when the second driving member 31 rotates the second rotating portion 32, the second buffer portion 33 abuts against the second collision point.
[0108] In this embodiment, the second buffer section 33 includes a plurality of second buffer sections 33, and the plurality of second buffer sections 33 are respectively installed on the first side wall 12, the second side wall 13, and the first partition plate 14. Alternatively, the plurality of second buffer sections 33 are installed on opposite sides of the second rotating section 32, so that when the second rotating section 32 collides with the first side wall 12 / second side wall 13, the first side wall 12 / second side wall 13 abuts against the second buffer section 33, or when the second rotating section 32 collides with the first partition plate 14, the first partition plate 14 abuts against the second buffer section 33, etc., are not limited here.
[0109] Alternatively, the second buffer portion 33 may be made of a compressible material such as foam, sponge, rubber mat, etc., but is not limited thereto. That is, the second buffer portion 33 does not use a rigid material.
[0110] In this embodiment, the second driving member 31 is fixedly mounted in the first cavity 111 / second cavity 112 of the mounting cavity 11, and the multiple mass blocks 222 of the second rotating part 32 are combined together without changing their relative positions, and the entire multiple mass blocks 222 are eccentric mass blocks that move synchronously.
[0111] As can be seen, when the rotor motor is driven, the first rotating part 22 / second rotating part 32 rapidly rotates around the rotor motor's rotation axis 211. When the first rotating part 22 / second rotating part 32 moves to two extreme positions, it collides with the corresponding first side wall 12 and second side wall 13 of the housing 1, respectively. When the first rotating part 22 / second rotating part 32 collides with the housing 1, a rapid braking effect occurs, and the housing 1 experiences a corresponding impact sensation. By driving multiple rotor motors in combination, two extreme state effects can be realized: one side experiences a unidirectional rotation sensation, and the other side experiences a unidirectional rotation sensation. The magnitude of the rotation sensation on both sides is related to the magnitude of the product of the corresponding force and force arm. Furthermore, by using long-term, high-frequency driving, two unidirectional rotation sensations on the same coordinate axis, i.e., clockwise rotation sensation and counterclockwise rotation sensation, can be rapidly generated at multiple frequencies.
[0112] Furthermore, when the first rotating part 22 / the second rotating part 32 move to the extreme position, the impact forces of the two first rotating parts 22 / the two second rotating parts 32 on the housing 1 are parallel to each other and the force arms are equal, thereby realizing the effect of a simple rotational sensation.
[0113] Of course, in actual use, the two limits of the same rotation can be used comprehensively, and a pair of force arms can be made longer based on the structural division, thereby obtaining better tactile feedback, and this is not limited here.
