Description

Technical Field

[0001] The present invention relates to the technical field of vibration devices, and in particular to an exciter and electronic equipment using the exciter. Background Art

[0002] Traditional vibration devices create the illusion of a force acting in a certain direction by continuously producing asymmetric vibrations. This type of vibration is also called anisotropic vibration.

[0003] There are currently two ways to achieve this force sense: one is to input an asymmetric signal into the linear resonator and use the human senses to create an illusion. In principle, this method can only produce a continuous directional force sense and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and the asymmetric signal will also produce redundant vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong sense of force by rapidly braking the linear resonator. This method can generate vibrations with large asymmetry, and has a small proportion of redundant vibrations, and the force sense is independent and clear. However, this method requires that the vibration part and the braking part are independently constructed, and the vibration part or the braking part is continuously moved to switch the energy storage and braking states, resulting in its inability to operate continuously at high speed, and the device structure is complex.

[0004] However, this type of device only achieves vibration in the linear direction and cannot generate a sense of force in the rotational direction. Summary of the invention

[0060] Traditional vibration devices create the illusion of a force acting in a certain direction by continuously producing asymmetric vibrations. This type of vibration is also called anisotropic vibration.

[0061] There are currently two ways to achieve this force sense: one is to input an asymmetric signal into the linear resonator and use the human senses to create an illusion. In principle, this method can only produce a continuous directional force sense and cannot achieve discrete vibration output. At the same time, the equivalent force felt in this way is small, and the asymmetric signal will also produce redundant vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong sense of force by rapidly braking the linear resonator. This method can generate vibrations with large asymmetry, and has a small proportion of redundant vibrations, and the force sense is independent and clear. However, this method requires that the vibration part and the braking part are independently constructed, and the vibration part or the braking part is continuously moved to switch the energy storage and braking states, resulting in its inability to operate continuously at high speed, and the device structure is complex.

[0062] However, this type of device only achieves vibration in the linear direction and cannot generate a sense of force in the rotational direction.

[0065] In this embodiment, the housing 1 of the exciter 100 is used to install, fix and protect the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5, that is, the housing 1 provides a mounting structure for the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5. It can be understood that the housing 1 can be a mounting shell, a mounting box, a box body and other structures, which are not limited here. The housing 1 has an installation cavity 11 for placing and installing the first rotating assembly 2, the second rotating assembly 3, the third rotating assembly 4 and the fourth rotating assembly 5. The installation cavity 11 can be a closed cavity, and of course the installation cavity 11 can also be an open cavity.

[0068] Optionally, the housing 1 is arranged in a square shape. Further, the housing 1 can be optionally a square or rectangular structure. In this embodiment, the first rotating assembly 2 and the second rotating assembly 3 are close to the second side wall 13, and the fourth rotating assembly 5 and the third rotating assembly 4 are close to the first side wall 12.

[0069] In this embodiment, the first rotating assembly 2 includes a first driving member 21 and a first rotating part 22. The first driving member 21 is disposed in the first cavity 111.

The second rotating assembly 3 includes a second driving member 31 and a second rotating part 32. The second driving member 31 is disposed in the first sub-cavity 1121. The second driving member 31 may be directly fixed to the inner wall of the housing 1, or may be installed in the first sub-cavity 1121 through other structures, such as a bracket or a mounting seat. The third rotating assembly 4 includes a third driving member 41 and a third rotating part 42. The third driving member 41 is disposed in the second sub-cavity 1122. The third driving member 41 may be directly fixed to the inner wall of the housing 1, or may be installed in the second sub-cavity 1122 through other structures, such as a bracket or a mounting seat. The fourth rotating assembly 5 includes a fourth driving member 51 and a fourth rotating portion 52. The fourth driving member 51 is disposed in the first cavity 111 and is spaced apart from the first driving member 21. The fourth driving member 51 may be directly fixed to the inner wall of the housing 1, or may be installed in the first cavity 111 through other structures, such as a bracket or a mounting seat. Optionally, the first rotating assembly 2 is disposed close to the second side wall 13, and the fourth rotating assembly 5 is disposed close to the first side wall 12.

[0070] In this embodiment, the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 are respectively connected to the output ends of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51, and are eccentrically arranged. It can be understood that the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can be an eccentric structure, or one end of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can be connected to the output end of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51, so that when the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51 drives the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 to rotate, the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 rotates around the first driving member 21 / the second driving member 31 / the third driving member 41 / The output end of the fourth driving member 51 makes a circular motion, that is, the position where the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 is connected to the output end of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51 is located at an eccentric position of the structure of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 itself (the position where the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 is connected to the output end of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51 does not coincide with the center of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52).

[0071] It should be noted that the structures of the first rotating component 2, the second rotating component 3, the third rotating component 4 and the fourth rotating component 5 in this embodiment are the same or similar, that is, the first rotating component 2, the second rotating component 3, the third rotating component 4 and the fourth rotating component 5 all include a driving member structure and a rotating part structure, and the rotating part structure is connected to the output end of the driving member structure and is eccentrically arranged. It can be understood that the rotating part structure itself can be an eccentric structure, or one end of the rotating part structure can be connected to the output end of the driving member structure, so that when the driving member structure drives the rotating part structure to rotate, the rotating part structure performs a circular motion around the output end of the driving member structure, that is, the output end of the driving member structure is located at an eccentric position of the rotating part structure itself.

[0072] In this embodiment, the actuator has a clockwise rotation tactile sensation by controlling the first rotating assembly 2 and the second rotating assembly 3 to work, and has a counterclockwise rotation tactile sensation by controlling the third rotating assembly 4 and the fourth rotating assembly 5 to work. It can be understood that the actuator 100 can generate two unidirectional rotation tactile sensations of the same coordinate axis at a fast and high frequency by long-term and high-frequency driving, that is, the actuator 100 generates a clockwise rotation tactile sensation and a counterclockwise rotation tactile sensation.

[0073] It can be understood that by simultaneously controlling the first driving member 21 and the second driving member 31 to synchronously drive the first rotating part 22 and the second rotating part 32, so that the first rotating part 22 and the second rotating part 32 simultaneously hit the second side wall 13 and the second partition 15, or the first rotating part 22 and the second rotating part 32 simultaneously hit the first partition 14, the effects of two extreme positions can be achieved, that is, when the first rotating part 22 and the second rotating part 32 simultaneously hit the second side wall 13 and the second partition 15, respectively, a torque can be generated in the clockwise direction, so that the exciter 100 can generate a force sense in the clockwise direction, that is, a unidirectional rotational touch is formed, and the first rotating part 22 and the second rotating part 32 simultaneously hit the first partition 14 to generate forces of the same magnitude and opposite directions, thereby offsetting each other, thereby ensuring that the exciter 100 can generate a unidirectional rotational force sense.

[0074] Of course, by simultaneously controlling the third driving member 41 and the fourth driving member 51 to synchronously drive the third rotating part 42 and the fourth rotating part 52, the third rotating part 42 and the fourth rotating part 52 respectively hit the second partition 15 and the first side wall 12 at the same time, or the third rotating part 42 and the fourth rotating part 52 hit the first partition 14 at the same time, so that the effects of two extreme positions can be achieved, that is, when the third rotating part 42 and the fourth rotating part 52 hit the second partition 15 and the first side wall 12 at the same time, they can generate torque in the counterclockwise direction, so that the exciter 100 can generate a force sense in the counterclockwise direction, that is, a unidirectional rotational touch is formed, and the third rotating part 42 and the fourth rotating part 52 hit the first partition 14 at the same time to generate forces of the same magnitude and opposite directions, thereby offsetting each other, thereby ensuring that the exciter 100 can generate a force sense in the unidirectional rotational direction.

[0075] At the same time, by setting the first rotating component 2 / second rotating component 3 / third rotating component 4 / fourth rotating component 5 as the first driving member 21 / second driving member 31 / third driving member 41 / fourth driving member 51 to drive the eccentrically set first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and generate a strong and clear sense of force.

[0076] It should be noted that the exciter 100 further includes a controller or a control structure, which can control the first driving member 21 and the second driving member 31 to drive the first rotating part 22 and the second rotating part 32 to rotate; or, the controller or the control structure can control the third driving member 41 and the fourth driving member 51 to drive the third rotating part 42 and the fourth rotating part 52 to rotate. It can be understood that the controller or the control structure can be a separate controller or a remote controller, or a control circuit or a control button integrated in the exciter 100, which is not limited here.

[0077] In this embodiment, if Figures 3 to 6 As shown, the first rotating assembly 2 and the second rotating assembly 3 are located between the extension lines of the second side wall 13 and the second partition plate 15 , and the third rotating assembly 4 and the fourth rotating assembly 5 are located between the extension lines of the first side wall 12 and the second partition plate 15 .

[0078] It should be noted that if Figure 3 As shown, the first driving member 21 and the second driving member 31 are controlled to rotate in the positive direction to drive the first rotating part 22 and the second rotating part 32 to rotate clockwise, so that the first rotating part 22 and the second rotating part 32 hit the second side wall 13 and the second partition plate 15 respectively at the same time, thereby generating a torque in the clockwise direction, so that the exciter 100 can generate a force sense in the clockwise rotation direction; as shown in FIG. Figure 4 As shown, the first driving member 21 and the second driving member 31 are controlled to rotate in opposite directions to drive the first rotating part 22 and the second rotating part 32 to rotate counterclockwise, so that the first rotating part 22 and the second rotating part 32 hit the first partition plate 14 at the same time, thereby generating forces of the same magnitude and opposite directions in the counterclockwise direction, thereby offsetting each other, thereby ensuring that the exciter 100 can generate a unidirectional clockwise rotation force sensation.

[0079] like Figure 5 As shown, the third driving member 41 and the fourth driving member 51 are controlled to rotate in the forward direction to drive the third rotating part 42 and the fourth rotating part 52 to rotate counterclockwise, so that the third rotating part 42 and the fourth rotating part 52 simultaneously hit the first side wall 12 and the second partition plate 15 respectively, thereby generating torque in the counterclockwise direction, so that the exciter 100 can generate a force sense in the counterclockwise direction; as shown in FIG. Figure 6 As shown, the third driving member 41 and the fourth driving member 51 are controlled to rotate in opposite directions to drive the third rotating part 42 and the fourth rotating part 52 to rotate clockwise, so that the third rotating part 42 and the fourth rotating part 52 hit the first partition plate 14 at the same time, thereby generating forces of the same magnitude and opposite directions in the clockwise direction, thereby offsetting each other, thereby ensuring that the exciter 100 can generate a unidirectional counterclockwise rotation force sensation.

[0080] It can be understood that the exciter 100 is defined to have a first state of clockwise rotation and a second state of counterclockwise rotation. In the first state, the exciter 100 is defined to have a function of controlling the first driving member 21 and the second driving member 31 to rotate forward to drive the first rotating part 22 and the second rotating part 32 to rotate clockwise, so that the first rotating part 22 and the second rotating part 32 simultaneously hit the first position of the second side wall 13 and the second partition 15 respectively, and controlling the first driving member 21 and the second driving member 31 to rotate reversely to drive the first rotating part 22 and the second rotating part 32 to rotate counterclockwise, so that the first rotating part 22 and the second rotating part 32 simultaneously hit the second position of the first partition 14. Figure 7 As shown, when two acceleration sensors are used to detect the vibration of the actuator 100, in the first position of the first state, the housing 1 of the actuator 100 has an obvious vibration sense and a clockwise rotation tactile sense, and in the second position of the first state, the housing 1 of the actuator 100 has no obvious tactile sense. Due to the limitation of the accuracy of the hand-held prototype, there is residual noise.

[0081] In the second state, the exciter 100 is defined to control the third driving member 41 and the fourth driving member 51 to rotate forward to drive the third rotating part 42 and the fourth rotating part 52 to rotate counterclockwise, so that the third rotating part 42 and the fourth rotating part 52 simultaneously hit the third position of the first side wall 12 and the second partition 15 respectively, and control the third driving member 41 and the fourth driving member 51 to rotate reversely to drive the third rotating part 42 and the fourth rotating part 52 to rotate clockwise, so that the third rotating part 42 and the fourth rotating part 52 simultaneously hit the fourth position of the first partition 14. Figure 8 As shown, when two acceleration sensors are used to detect the vibration of the actuator 100, at the third position in the second state, the housing 1 of the actuator 100 has an obvious vibration sense and a clockwise rotation tactile sense, and at the fourth position in the second state, the housing 1 of the actuator 100 has no obvious tactile sense. Due to the limitation of the accuracy of the hand-held prototype, there is residual noise.

[0082] In this embodiment, when the exciter 100 is in the first state of clockwise rotation, the controller or control structure only controls the first driving member 21 and the second driving member 31 of the first rotating assembly 2 and the second rotating assembly 3 to drive the first rotating part 22 and the second rotating part 32 to rotate, and at this time, the third driving member 41 and the fourth driving member 51 of the third rotating assembly 4 and the fourth rotating assembly 5 are in a power-off state. When the exciter 100 is in the second state of counterclockwise rotation, the controller or control structure only controls the third driving member 41 and the fourth driving member 51 of the third rotating assembly 4 and the fourth rotating assembly 5 to drive the third rotating part 42 and the fourth rotating part 52 to rotate, and at this time, the first driving member 21 and the second driving member 31 of the first rotating assembly 2 and the second rotating assembly 3 are in a power-off state.

[0083] In this embodiment, in order to ensure that the controller or control structure controls the first rotating component 2 and the second rotating component 3 or the third rotating component 4 and the fourth rotating component 5 to achieve synchronous action, in the initial state, the first rotating component 2 and the second rotating component 3 are centrally symmetrically arranged with the first partition 14 between the second partition 15 and the second side wall 13, that is, the first rotating component 2 and the second rotating component 3 are centrally symmetrically arranged on the right side of the shell 1; the third rotating component 4 and the fourth rotating component 5 are centrally symmetrically arranged with the first partition 14 between the second partition 15 and the first side wall 12, that is, the third rotating component 4 and the fourth rotating component 5 are centrally symmetrically arranged on the left side of the shell 1.

[0084] The exciter 100 of the present invention forms an installation cavity 11 in the shell 1, so as to use the installation cavity 11 to install, fix and protect the first rotating component 2, the second rotating component 3, the third rotating component 4 and the fourth rotating component 5. The shell 1 has a first side wall 12 and a second side wall 13 that are arranged opposite to each other. The first partition plate 14 and the second partition plate 15 are arranged in the installation cavity 11 of the shell 1, so that the two ends of the first partition plate 14 are respectively connected to the first side wall 12 and the second side wall 13, and the installation cavity 11 is divided into a first cavity 111 and a second cavity 112. One end of the second partition plate 15 is connected to the first partition plate 14 and is located in the second cavity 112, so that the second partition plate 15 and the first partition plate 14 are connected to each other. A partition 14 and the second side wall 13 are enclosed to form a first sub-cavity 1121, and the second partition 15, the first partition 14 and the first side wall 12 are enclosed to form a second sub-cavity 1122. In this way, the first cavity 111 can be used to install and fix the first rotating component 2 and the fourth rotating component 5, and the first sub-cavity 1121 and the second sub-cavity 1122 of the second cavity 112 are used to install and fix the second rotating component 3 and the third rotating component 4 respectively, and by setting the first rotating component 2 as the first driving member 21 and the first rotating part 22, the first rotating part 22 is connected to the output end of the first driving member 21 and is eccentrically set, and the second rotating component 3 is set as the second driving member 31 and the second The first driving member 21 and the second driving member 31 are synchronously driven by the first rotating part 22 and the second rotating part 32, so that the first rotating part 22 and the second rotating part 32 simultaneously hit the first partition plate 1 4 or simultaneously hit the second side wall 13 and the second partition 15 respectively, so that the exciter 100 has a first state of clockwise rotation, and by controlling the third driving member 41 and the fourth driving member 51 to synchronously drive the third rotating part 42 and the fourth rotating part 52, so that the third rotating part 42 and the fourth rotating part 52 simultaneously hit the first partition 14 or simultaneously hit the second partition 15 and the first side wall 12 respectively, so that the exciter 100 has a second state of counterclockwise rotation, so that the exciter 100 can use long-term, high-frequency driving to generate fast, multi-frequency two-way rotation tactile sensations on the same coordinate axis, that is, the exciter 100 generates clockwise rotation tactile sensations and counterclockwise rotation tactile sensations. At the same time, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and generate a strong and clear sense of force.

[0085] Optionally, the structure of the first rotating assembly 2 is the same as that of the second rotating assembly 3; the structure of the third rotating assembly 4 is the same as that of the fourth rotating assembly 5. Optionally, the structure of the first rotating assembly 2, the structure of the second rotating assembly 3, the structure of the third rotating assembly 4 and the structure of the fourth rotating assembly 5 are all the same.

[0086] In one embodiment, if Figures 1 to 6 As shown, the first driving member 21, the second driving member 31, the third driving member 41 and the fourth driving member 51 are all rotor motors, the rotor motors are provided with a rotating shaft 211, the first rotating part 22, the second rotating part 32, the third rotating part 42 and the fourth rotating part 52 are provided with an axial hole 221, the axial hole 221 is eccentrically arranged on the first rotating part 22, the second rotating part 32, the third rotating part 42 and the fourth rotating part 52, and the rotating shaft 211 is penetrated into the axial hole 221.

[0087] It is understandable that the structure of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can be a regular shape or an irregular shape. Optionally, the shape of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can be circular, elliptical, square, triangular or polygonal. The center of the shaft hole 221 does not coincide with the shape of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52. Of course, the shape of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can also be an irregular shape, which is not limited here.

[0088] In this embodiment, by setting the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51 as a rotor motor, and utilizing the rotor motor to drive the rotating structure of the eccentrically arranged first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and generate a strong and clear sense of force.

[0089] It should be noted that in order to further ensure that the exciter 100 produces a strong and clear sense of force in the unidirectional rotation direction. The first rotating component 2 in the first cavity 111 and the second rotating component 3 in the first sub-cavity 1121 are centrally symmetrically arranged with the first partition 14 between the second partition 15 and the second side wall 13; the third rotating component 4 in the second sub-cavity 1122 and the fourth rotating component 5 in the first cavity 111 are centrally symmetrically arranged with the first partition 14 between the second partition 15 and the first side wall 12. Optionally, the weight of the first rotating part 22 and the second rotating part 32 are the same, and the weight of the third rotating part 42 and the fourth rotating part 52 are the same. The shape contours of the first rotating part 22 and the second rotating part 32 are the same, and the shape contours of the third rotating part 42 and the fourth rotating part 52 are the same.

[0090] It can be understood that in order to further ensure that the exciter 100 generates a strong and clear force sense in the unidirectional rotation direction, the driving frequencies of the first driving member 21 and the second driving member 31 are the same, and the driving frequencies of the third driving member 41 and the fourth driving member 51 are the same. The driving voltages of the first driving member 21 and the second driving member 31 are the same, and the driving voltages of the third driving member 41 and the fourth driving member 51 are the same.

[0091] In one embodiment, the first rotating part 22, the second rotating part 32, the third rotating part 42, and the fourth rotating part 52 each include at least one mass block 222. It can be understood that the material of the mass block 222 can be a metal material, that is, the mass block 222 is made of a metal material. Of course, the mass block 222 can also be a non-metallic material, that is, the mass block 222 is made of a non-metallic material.

[0092] It should be noted that in order to make the exciter 100 produce a strong and clear sense of force, the mass block 222 of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 adopts a relatively heavy structure. Optionally, the mass block 222 is made of metal. In order to further improve the mass of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52, the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can also be provided with a counterweight block or multiple mass blocks 222 on the mass block 222, and the counterweight block or the multiple mass blocks 222 are located in the radial direction or circumferential direction of the rotation center of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52, and the axial hole 221 is located in the eccentric position of the formed overall first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 (that is, the axial hole 221 does not coincide with the center of the formed overall first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52).

[0093] In this embodiment, if Figures 1 to 6As shown, the number of mass blocks 222 of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 can be one, two, three, four or more, etc., which is not limited here. The shaft hole 221 on the mass block 222 connected to the rotating shaft 211 of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51 among the multiple mass blocks 222 is located at the eccentric position of the mass block 222, and at this time, another mass block 222 is connected to the radial direction or circumferential direction of the mass block 222, 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.

[0094] Of course, the axial hole 221 can also be located at the center position of the mass block 222. In this case, another mass block 222 is connected to one side of the mass block 222, so that the overall first rotating part 22 / second rotating part 32 / third rotating part 42 / fourth rotating part 52 has an eccentric structure, which is not limited here.

[0095] Optionally, the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 includes three mass blocks 222, one mass block 222 is connected to the output end of the first driving member 21 / the second driving member 31 / the third driving member 41 / the fourth driving member 51, and is eccentrically arranged; the other two mass blocks 222 are connected and arranged in sequence along the radial direction of the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52; or, the other two mass blocks 222 are connected and arranged in sequence along the circumferential direction of the mass block 222.

[0096] In one embodiment, the first partition plate 14 is vertically disposed to the first side wall 12 , the first partition plate 14 is vertically disposed to the second side wall 13 , and the first partition plate 14 is located in the middle of the first side wall 12 and the second side wall 13 .

[0097] Understandable, such as Figures 3 to 6 As shown, the housing 1 may be in a square shape, the first side wall 12 and the second side wall 13 may be arranged in parallel, and the first partition plate 14 is located in the middle of the first side wall 12 and the second side wall 13 to divide the installation cavity 11 into two halves.

[0098] Of course, in other embodiments, the first partition 14 may not be arranged perpendicular to the first side wall 12, and the first partition 14 may not be arranged perpendicular to the second side wall 13. For example, when the fourth rotating part 52 / the first rotating part 22 is arranged in a fan shape, when the fourth driving member 51 / the first driving member 21 drives the fourth rotating part 52 / the first rotating part 22 to rotate 90° to collide with the first side wall 12 / the second side wall 13 or the first partition 14, the first partition 14 and the first side wall 12 may not be arranged perpendicularly, and the first partition 14 and the second side wall 13 may not be arranged perpendicularly, which is not limited here. It can be understood that the first side wall 12 / the second side wall 13 can be arranged as a two-section structure arranged at an angle, in which case the first partition 14 is connected to the angle of the first side wall 12 / the second side wall 13, and in which case the first partition 14 is not arranged perpendicularly to at least one section of the first side wall 12 / the second side wall 13, which is not limited here.

[0099] In this embodiment, the second partition 15 is arranged perpendicularly to the first partition 14 and is located in the middle of the first partition 14. It can be understood that the second partition 15 is located in the middle of the first partition 14, and the second partition 15 is located between the first side wall 12 and the second side wall 13, and is arranged parallel to the first side wall 12 and the second side wall 13, so that the second partition 15 divides the second cavity 112 in half. Optionally, the first sub-cavity 1121 and the second sub-cavity 1122 are arranged symmetrically with respect to the second partition 15.

[0100] Of course, in other embodiments, the second partition 15 may not be arranged perpendicularly to the first partition 14. For example, when the second rotating portion 32 / the third rotating portion 42 is arranged in a fan shape, when the second driving member 31 / the third driving member 41 drives the second rotating portion 32 / the third rotating portion 42 to rotate 90° to collide with the second partition 15 or the first partition 14, the second partition 15 and the first partition 14 may not be arranged perpendicularly, which is not limited here.

[0101] It can be understood that in order to realize the first rotating part 22 and the second rotating part 32 of the first rotating component 2 and the second rotating component 3 located in the right part of the housing 1 to realize the same direction of clockwise or counterclockwise rotation, the first rotating component 2 in the first cavity 111 and the second rotating component 3 in the first sub-cavity 1121 are centrally symmetrically arranged. In order to realize the third rotating part 42 and the fourth rotating part 52 of the third rotating component 4 and the fourth rotating component 5 located in the left part of the housing 1 to realize the same direction of counterclockwise or clockwise rotation, the third rotating component 4 in the second sub-cavity 1122 and the fourth rotating component 5 in the first cavity 111 are centrally symmetrically arranged.

[0102] Optionally, the first rotating assembly 2 and the second rotating assembly 3 are centrally symmetrically arranged, and the third rotating assembly 4 and the fourth rotating assembly 5 are centrally symmetrically arranged.

[0103] In this embodiment, if Figures 3 to 6 As shown, the first driving member 21 is arranged near the connection between the second side wall 13 and the first partition 14, and the fourth driving member 51 is arranged near the connection between the first side wall 12 and the first partition 14, so that the first driving member 21 and the fourth driving member 51 are symmetrically arranged relative to the second partition 15. The second driving member 31 is arranged near the connection between the second partition 15 and the first partition 14, and the third driving member 41 is arranged near the connection between the second partition 15 and the first partition 14, so that the second driving member 31 and the third driving member 41 are symmetrically arranged relative to the second partition 15.

[0104] In one embodiment, when the first rotating portion 22 and the second rotating portion 32 respectively hit the second side wall 13 and the second partition 15 simultaneously, the first rotating portion 22 and the second rotating portion 32 respectively form a first impact point 131 and a second impact point 151 on the second side wall 13 and the second partition 15, and the distance from the first impact point 131 to the first partition 14 is the same as the distance from the second impact point 151 to the first partition 14.

[0105] In this embodiment, if Figure 3 As shown, in order to ensure that the first impact point 131 and the second impact point 151 formed by the first rotating part 22 and the second rotating part 32 respectively hitting the second side wall 13 and the second partition 15 at the same distance from the first partition 14, so that the force generated by the exciter 100 in the clockwise rotation direction remains consistent and the user experience is improved, the output end of the first driving member 21 (that is, the rotation center of the first rotating part 22) is located on the bisector of the angle formed by the second side wall 12 and the first partition 14, and the output end of the second driving member 31 (that is, the rotation center of the second rotating part 32) is located on the bisector of the angle formed by the second partition 15 and the first partition 14.

[0106] In one embodiment, when the third rotating portion 42 and the fourth rotating portion 52 respectively hit the second partition plate 15 and the first side wall 12 simultaneously, the third rotating portion 42 and the fourth rotating portion 52 respectively form a third impact point 152 and a fourth impact point 121 on the second partition plate 15 and the first side wall 12, and the distance from the third impact point 152 to the first partition plate 14 is the same as the distance from the fourth impact point 121 to the first partition plate 14.

[0107] In this embodiment, if Figure 5As shown, in order to ensure that the third impact point 152 and the fourth impact point 121 formed by the third rotating part 42 and the fourth rotating part 52 respectively hitting the second partition 15 and the first side wall 12 at the same time and having the same distance from the first partition 14, so that the force generated by the exciter 100 in the counterclockwise rotation direction remains consistent and the user experience is improved, the output end of the third driving member 41 (that is, the rotation center of the third rotating part 42) is located on the bisector of the angle formed by the second partition 15 and the first partition 14, and the output end of the fourth driving member 51 (that is, the rotation center of the fourth rotating part 52) ​​is located on the bisector of the angle formed by the first side wall 12 and the first partition 14.

[0108] In one embodiment, if Figures 3 to 6 As shown, when the first rotating part 22 hits the first side wall 12, the first rotating part 22 forms a first impact point on the second side wall 13, when the second rotating part 32 hits the second partition 15, the second rotating part 32 forms a second impact point on the second partition 15, when the third rotating part 42 hits the second partition 15, the third rotating part 42 forms a third impact point on the second partition 15, and when the fourth rotating part 52 hits the first side wall 12, the fourth rotating part 52 forms a fourth impact point on the first side wall 12. Optionally, the distance from the first impact point to the first partition 14 is the same as the distance from the fourth impact point to the first partition 14. The distance from the second impact point to the first partition 14 is the same as the distance from the third impact point to the first partition 14.

[0109] It can be understood that the shape profile of the first rotating part 22 / the second rotating part 32 is the same as the shape profile of the third rotating part 42 / the fourth rotating part 52, that is, the structure of the first rotating component 2 / the second rotating component 3 is the same as the structure of the third rotating component 4 / the fourth rotating component 5.

[0110] In one embodiment, if Figure 3 and Figure 4 As shown, the angle at which the first driving member 21 drives the first rotating part 22 to rotate can be selected to be 90°, and the angle at which the second driving member 31 drives the second rotating part 32 to rotate can be selected to be 90°. It is defined that when the first driving member 21 / the second driving member 31 drives the first rotating part 22 / the second rotating part 32 to rotate forward, the first rotating part 22 and the second rotating part 32 simultaneously hit the second side wall 13 and the second partition 15 respectively; it is defined that when the first driving member 21 / the second driving member 31 drives the first rotating part 22 / the second rotating part 32 to rotate reversely, the first rotating part 22 / the second rotating part 32 simultaneously hit the first partition 14.

[0111] In this embodiment, if Figure 1 , Figures 3 to 6As shown, the first side wall 12 and the second side wall 13 of the housing 1 are optionally arranged in parallel. The first partition 14 is perpendicular to the first side wall 12 and the second side wall 13 and is located in the middle of the first side wall 12 and the second side wall 13.

[0124] In this embodiment, if Figures 1 to 6 As shown, by providing the first buffer portion 23, the first buffer portion 23 can be used to adjust the impact force of the first rotating portion 22 and the susceptible frequency of the vibration wave, so that Figure 7 The tip of the middle wave peak is sharper, and at the same time, the first buffer portion 23 also has a noise reduction effect.

[0125] It can be understood that when the first rotating portion 22 impacts the second side wall 13 / first partition plate 14 , the first rotating portion 22 forms a first impact point 131 on the second side wall 13 / first partition plate 14 , and the first impact point 131 coincides with the first impact location.

Of course, the first buffer portion 23 can also be disposed on the first rotating portion 22, so that when the first driving member 21 drives the first rotating portion 22 to rotate, the first buffer portion 23 abuts against the first impact point.

[0127] In this embodiment, the first buffer portion 23 includes a plurality of first buffer portions 23, and the plurality of first buffer portions 23 are respectively arranged on the second side wall 13 and the first partition plate 14. Alternatively, the plurality of first buffer portions 23 are arranged on opposite sides of the first rotating portion 22, so that when the first rotating portion 22 hits the second side wall 13 / first partition plate 14, the second side wall 13 / first partition plate 14 abuts against the first buffer portion 23, which is not limited here.

[0128] Optionally, the first buffer portion 23 is made of a compressible material, such as foam, sponge, rubber pad, etc., which is not limited here. That is, the first buffer portion 23 is not made of a rigid material.

[0129] In this embodiment, the first driving member 21 is fixedly installed in the first cavity 111 of the installation cavity 11, and its relative position does not change. The multiple mass blocks 222 of the first rotating part 22 are combined as a whole, and the multiple mass blocks 222 as a whole are eccentric mass blocks that move synchronously.

[0130] In one embodiment, it is defined that when the second rotating portion 32 collides with the second partition 15 or the first partition 14, a second impact point is formed on the second partition 15 or the first partition 14, and the second rotating component 3 also includes a second buffer portion 33; the second buffer portion 33 is arranged on the second partition 15 and / or the first partition 14, and is located at the second impact point; or, the second buffer portion 33 is arranged on the second rotating portion 32, and when the second driving member 31 drives the second rotating portion 32 to rotate, the second buffer portion 33 abuts against the second impact point.

[0131] In this embodiment, if Figures 1 to 6 As shown, by providing the second buffer portion 33, the second buffer portion 33 can be used to adjust the impact force of the second rotating portion 32 and the susceptible frequency of the vibration wave. Figure 7 The tip of the middle wave peak is sharper, and at the same time, the second rotating part 32 also has a noise reduction effect.

[0132] It can be understood that when the second rotating portion 32 impacts the second partition plate 15 / the first partition plate 14, the second rotating portion 32 forms a second impact point 151 on the second partition plate 15 / the first partition plate 14, and the second impact point 151 coincides with the second impact location.

[0133] In this embodiment, the second buffer portion 33 can be disposed on the second partition plate 15 and / or the first partition plate 14 of the housing 1 and located at the second impact point. Of course, the second buffer portion 33 can also be disposed on the second rotating portion 32, so that when the second driving member 31 drives the second rotating portion 32 to rotate, the second buffer portion 33 abuts against the second impact point.

[0134] In this embodiment, the second buffer portion 33 includes a plurality of second buffer portions 33, and the plurality of second buffer portions 33 are respectively arranged on the second partition plate 15 and the first partition plate 14. Alternatively, the plurality of second buffer portions 33 are arranged on opposite sides of the second rotating portion 32, so that when the second rotating portion 32 hits the second partition plate 15 / the first partition plate 14, the second partition plate 15 / the first partition plate 14 abuts against the second buffer portion 33, which is not limited here.

[0135] Optionally, the second buffer portion 33 is made of a compressible material, such as foam, sponge, rubber pad, etc., which is not limited here. That is, the second buffer portion 33 is not made of a rigid material.

[0136] In this embodiment, the second driving member 31 is fixedly installed in the first sub-cavity 1121 of the installation cavity 11, and its relative position does not change. The multiple mass blocks 222 of the second rotating part 32 are combined as a whole, and the multiple mass blocks 222 as a whole are eccentric mass blocks that move synchronously.

[0137] In one embodiment, it is defined that when the third rotating portion 42 collides with the second partition 15 or the first partition 14, a third impact point is formed on the second partition 15 or the first partition 14, and the third rotating component 4 also includes a third buffer portion 43; the third buffer portion 43 is provided on the second partition 15 and / or the first partition 14, and is located at the third impact point; or, the third buffer portion 43 is provided on the third rotating portion 42, and when the third driving member 41 drives the third rotating portion 42 to rotate, the third buffer portion 43 abuts against the third impact point.

[0138] In this embodiment, if Figures 1 to 6 As shown, by providing the third buffer portion 43, the third buffer portion 43 can be used to adjust the impact force of the third rotating portion 42, and the third buffer portion 43 can be used to adjust the susceptible frequency of the vibration wave, so that Figure 8 The tip of the middle wave peak is sharper, and the third rotating part 42 also has a noise reduction effect.

[0139] It can be understood that when the third rotating portion 42 impacts the second partition plate 15 / the first partition plate 14, the third rotating portion 42 forms a third impact point 152 on the second partition plate 15 / the first partition plate 14, and the third impact point 152 coincides with the third impact location.

[0140] In this embodiment, the third buffer portion 43 can be disposed on the second partition plate 15 and / or the first partition plate 14 of the housing 1 and located at the third impact point. Of course, the third buffer portion 43 can also be disposed on the third rotating portion 42, so that when the third driving member 41 drives the third rotating portion 42 to rotate, the third buffer portion 43 abuts against the third impact point.

[0141] In this embodiment, the third buffer part 43 includes a plurality of third buffer parts 43, and the plurality of third buffer parts 43 are respectively arranged on the second partition plate 15 and the first partition plate 14. Alternatively, the plurality of third buffer parts 43 are arranged on opposite sides of the third rotating part 42, so that when the third rotating part 42 hits the second partition plate 15 / the first partition plate 14, the second partition plate 15 / the first partition plate 14 abuts against the third buffer parts 43, which is not limited here.

[0142] Optionally, the third buffer portion 43 is made of a compressible material, such as foam, sponge, rubber pad, etc., which is not limited here. That is, the third buffer portion 43 is not made of a rigid material.

[0143] In this embodiment, the third driving member 41 is fixedly installed in the second sub-cavity 1122 of the installation cavity 11, and its relative position does not change. The multiple mass blocks 222 of the third rotating part 42 are combined as a whole, and the multiple mass blocks 222 as a whole are eccentric mass blocks that move synchronously.

[0144] In one embodiment, it is defined that when the fourth rotating portion 52 collides with the first side wall 12 or the first partition 14, a fourth impact point is formed on the first side wall 12 or the first partition 14, and the fourth rotating component 5 also includes a fourth buffer portion 53; the fourth buffer portion 53 is disposed on the first side wall 12 and / or the first partition 14 and is located at the fourth impact point; or, the fourth buffer portion 53 is disposed on the fourth rotating portion 52, and when the fourth driving member 51 drives the fourth rotating portion 52 to rotate, the fourth buffer portion 53 abuts against the fourth impact point.

[0145] In this embodiment, if Figures 1 to 6 As shown, by providing the fourth buffer portion 53, the fourth buffer portion 53 can be used to adjust the impact force of the fourth rotating portion 52 and the susceptible frequency of the vibration wave, so that Figure 8 The tip of the middle wave peak is sharper, and at the same time, the fourth buffer portion 53 also has a noise reduction effect.

[0146] It can be understood that when the fourth rotating portion 52 hits the first side wall 12 / first partition plate 14 , the fourth rotating portion 52 forms a fourth impact point 121 on the first side wall 12 / first partition plate 14 , and the fourth impact point 121 coincides with the fourth impact location.

[0147] In this embodiment, the fourth buffer portion 53 can be disposed on the first side wall 12 and / or the first partition plate 14 of the housing 1 and located at the fourth impact point. Of course, the fourth buffer portion 53 can also be disposed on the fourth rotating portion 52, so that when the fourth driving member 51 drives the fourth rotating portion 52 to rotate, the fourth buffer portion 53 abuts against the fourth impact point.

[0148] In this embodiment, the fourth buffer portion 53 includes a plurality of fourth buffer portions 53, and the plurality of fourth buffer portions 53 are respectively arranged on the first side wall 12 and the first partition plate 14. Alternatively, the plurality of fourth buffer portions 53 are arranged on opposite sides of the fourth rotating portion 52, so that when the fourth rotating portion 52 hits the first side wall 12 / the first partition plate 14, the first side wall 12 / the first partition plate 14 abuts against the fourth buffer portion 53, which is not limited here.

[0149] Optionally, the fourth buffer portion 53 is made of a compressible material, such as foam, sponge, rubber pad, etc., which is not limited here. That is, the fourth buffer portion 53 is not made of a rigid material.

[0150] In this embodiment, the fourth driving member 51 is fixedly installed in the first cavity 111 of the installation cavity 11, and its relative position does not change. The multiple mass blocks 222 of the fourth rotating part 52 are combined as a whole, and the multiple mass blocks 222 as a whole are eccentric mass blocks that move synchronously.

[0151] It can be understood that when the rotor motor is driven, the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 rotates rapidly around the rotating shaft 211 of the rotor motor. When the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 moves to two extreme motion positions, they collide with the corresponding second side wall 13 / the second partition 15 and the second partition 15 / the first side wall 12 of the shell 1, respectively. When the first rotating part 22 / the second rotating part 32 / the third rotating part 42 / the fourth rotating part 52 collides with the shell 1, a rapid braking effect is generated, and the shell 1 receives a corresponding impact tactile sensation. By driving multiple rotor motors in combination, the effects of two extreme states can be achieved, that is, a unidirectional rotation tactile sensation on one side and a rotation tactile sensation in the same direction on the other side. The magnitude of the rotation tactile sensation on both sides is related to the magnitude of the product of the corresponding force and the lever arm. Then, long-term, high-frequency driving is used to generate fast, multi-frequency two-way rotation touches on the same coordinate axis, namely, clockwise rotation touch and counterclockwise rotation touch.

[0152] It should be noted that when the first rotating part 22 / the second rotating part 32 moves to the extreme position, the impact force of the first rotating part 22 / the second rotating part 32 on the housing 1 is parallel to each other and the force arm is equal, thereby achieving a pure clockwise rotation tactile effect. When the third rotating part 42 / the fourth rotating part 52 moves to the extreme position, the impact force of the third rotating part 42 / the fourth rotating part 52 on the housing 1 is parallel to each other and the force arm is equal, thereby achieving a pure counterclockwise rotation tactile effect.

[0153] It can be understood that in the state of motion cancellation, when the first rotating part 22 and the second rotating part 32 rotate counterclockwise and collide with the first partition 14, the two impact forces generated by the first rotating part 22 and the second rotating part 32 on the shell 1 coincide with the line connecting the center of mass of the first rotating part 22 and the second rotating part 32, so that the shell 1 is subjected to two forces of equal magnitude and opposite directions, thereby achieving the effect of motion impact cancellation. In another state, that is, when the first rotating part 22 and the second rotating part 32 rotate clockwise and collide with the second side wall 13 and the second partition 15, the impact forces of the first rotating part 22 and the second rotating part 32 on the shell 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple clockwise rotation touch.

[0154] Of course, when the third rotating part 42 and the fourth rotating part 52 rotate clockwise and collide with the first partition 14, the two impact forces generated by the third rotating part 42 and the fourth rotating part 52 on the shell 1 coincide with the line connecting the center of mass of the third rotating part 42 and the fourth rotating part 52, so that the shell 1 is subjected to two forces of equal magnitude and opposite directions, thereby achieving the effect of motion impact offset. In another state, that is, when the third rotating part 42 and the fourth rotating part 52 rotate counterclockwise and collide with the first side wall 12 and the second partition 15, the impact forces of the third rotating part 42 and the fourth rotating part 52 on the shell 1 are parallel to each other and the force arms are equal, thereby achieving the effect of a simple counterclockwise rotation touch.

[0155] In actual use, the two limits of the same rotation can be utilized in combination, or one set of force arms can be made longer according to the splitting of the structure to obtain better tactile feedback, which is not limited here.
