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 relatively small, and the asymmetric signal will also produce unnecessary vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong force sense by rapidly braking the linear resonator. This method can generate a large asymmetric vibration, and has the characteristics of a small proportion of unnecessary vibration, and a separate and clear force sense. However, this method requires the vibration part and the braking part to be independently constructed, and the vibration part or the braking part must be 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 linear vibration and cannot generate a sense of force in the rotational direction. Summary of the Invention

The rotating part rotates so that the two first rotating parts hit the first side wall and the second side wall respectively at the same time, or the two first rotating parts hit the first partition at the same time, so that the effects of two extreme states can be achieved, that is, when the two first rotating parts hit the first side wall and the second side wall respectively at the same time, torque can be generated in the direction of rotation, so that the exciter can generate a force sense in the direction of rotation, that is, a unidirectional rotation touch is formed, and the two first rotating parts hit the first partition at the same time to generate forces of the same magnitude and opposite directions, thereby offsetting each other; at the same time, by setting the first rotating component as a first driving member to drive the rotating structure of the eccentrically arranged first rotating part, not only the structure of the exciter is effectively simplified, but also the exciter can achieve high-speed continuous action and generate a strong and clear sense of force.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings).

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] 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.

[0054] 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 relatively small, and the asymmetric signal will also produce unnecessary vibrations, making it difficult to obtain a clear sense of direction. The other is to generate a strong force sense by rapidly braking the linear resonator. This method can generate a large asymmetric vibration, and has the characteristics of a small proportion of unnecessary vibration, and a separate and clear force sense. However, this method requires the vibration part and the braking part to be independently constructed, and the vibration part or the braking part must be 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.

[0055] However, this type of device only achieves linear vibration and cannot generate a sense of force in the rotational direction.

[0056] Based on the above concepts and problems, the present invention proposes an actuator 100. It is understood that actuator 100 can be applied to electronic devices, including tactile displays, tactile interfaces, force feedback devices, vibrating feeders, beauty products, personal hygiene products, personal entertainment products, personal massagers, wood-cutting machines, and earthquake vibrators. Examples include wireless game controllers, mobile motion controllers for sports games, wireless steering wheels, and remote controllers for sports games in gaming consoles, among others, without limitation.

[0057] Please refer to Figures 1 to 6 As shown, in an embodiment of the present invention, the exciter 100 includes a shell 1 and two first rotating components 2, the shell 1 has an installation cavity 11 and opposite first and second side walls 12 and 13, the shell 1 is also provided with a first partition 14 connecting the first side wall 12 and the second side wall 13, the first partition 14 divides the installation cavity 11 into a first cavity 111 and a second cavity 112, one first rotating component 2 is arranged in the first cavity 111, and the other first rotating component 2 is arranged in the second cavity 112, each first rotating component 2 includes a first driving member 21 and a first rotating part 22, the first rotating part 22 is connected to the output end of the first driving member 21, and is eccentrically arranged; wherein the two first driving members 21 synchronously drive the two first rotating parts 22 to rotate, so that the two first rotating parts 22 simultaneously hit the first partition 14 or simultaneously hit the first side wall 12 and the second side wall 13 respectively.

[0058] In this embodiment, the housing 1 of the actuator 100 is used to mount, secure, and protect the two first rotating assemblies 2 and other components. Specifically, the housing 1 provides a mounting structure for the two first rotating assemblies 2 and other components. It is understood that the housing 1 may be a mounting shell, mounting box, or box, and the like, without limitation. The housing 1 has a mounting cavity 11 for placing and mounting the two first rotating assemblies 2 and other components. The mounting cavity 11 may be a closed cavity, or alternatively, an open cavity.

[0059] It is understandable that the housing 1 can be an integral structure or a split structure. In order to facilitate the disassembly and assembly of the two first rotating assemblies 2 and other components, the housing 1 can be optionally configured as a split structure. That is, the housing 1 includes a first housing and a second housing, which are docked and connected to form an installation cavity 11. It should be noted that the housing 1 can be a regular shape or an irregular shape, such as a circular, elliptical, directional, triangular or other polygonal regular shape, or other irregular shapes, which are not limited here.

[0060] In this embodiment, in order to enable the actuator 100 to generate a sense of force in the rotational direction, the housing 1 has a first side wall 12 and a second side wall 13 arranged opposite to each other. The first side wall 12 and the second side wall 13 can be the outer wall of the housing 1, or can be a side wall or partition structure arranged in the installation cavity 11 of the housing 1, and are not limited here. By providing a first partition 14 in the installation cavity 11 of the housing 1, so that the two ends of the first partition 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, a first rotating component 2 is installed and fixed by the first cavity 111, and another first rotating component 2 is installed and fixed by the second cavity 112.

[0061] Optionally, the housing 1 is square in shape. Furthermore, the housing 1 can optionally 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 disposed within the first cavity 111 / second cavity 112. The first driving member 21 can be directly fixed to the inner wall of the housing 1 or mounted within the first cavity 111 / second cavity 112 via other structures, such as a bracket or mounting base.

[0062] In this embodiment, the first rotating portion 22 is connected to the output end of the first driving member 21 and is eccentrically arranged. It is understandable that the first rotating portion 22 can be an eccentric structure, or one end of the first rotating portion 22 can be connected to the output end of the first driving member 21, so that when the first driving member 21 drives the first rotating portion 22 to rotate, the first rotating portion 22 performs a circular motion around the output end of the first driving member 21, that is, the position where the first rotating portion 22 is connected to the output end of the first driving member 21 is located at an eccentric position of the first rotating portion 22 itself (the position where the first rotating portion 22 is connected to the output end of the first driving member 21 does not coincide with the center of the first rotating portion 22).

[0063] It can be understood that by controlling the two first driving members 21 to synchronously drive the two first rotating parts 22 to rotate, the two first rotating parts 22 are made to hit the first side wall 12 and the second side wall 13 at the same time, or the two first rotating parts 22 are made to hit the first partition 14 at the same time, so that the effects of two extreme positions can be achieved, that is, when the two first rotating parts 22 hit the first side wall 12 and the second side wall 13 at the same time, torque can be generated in the rotation direction, so that the exciter 100 can generate a force sense in the rotation direction, that is, a unidirectional rotational touch is formed, and the two first rotating parts 22 hit the first partition 14 at the same time to generate forces of the same size and opposite directions, thereby offsetting each other, thereby ensuring that the exciter 100 can generate a force sense in the unidirectional rotation direction.

[0064] At the same time, by setting the first rotating component 2 as a rotating structure in which the first driving member 21 drives the eccentrically arranged first rotating part 22, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and produce a strong and clear sense of force.

[0065] It should be noted that the actuator 100 further includes a controller or control structure, which is capable of controlling the two first driving members 21 to drive the two first rotating parts 22 to rotate. It is understood that the controller or control structure can be a separate controller or remote control, or a control circuit or control button integrated into the actuator 100, and is not limited here.

[0066] In this embodiment, if Figure 3 As shown, the two first driving members 21 are controlled to rotate in the forward direction to drive the two first rotating parts 22 to rotate clockwise, so that the two first rotating parts 22 simultaneously hit the first side wall 12 and the second side wall 13 respectively, thereby generating torque in the clockwise direction, so that the exciter 100 can generate a force sense in the clockwise direction; Figure 4As shown, the two first driving members 21 are controlled to rotate in opposite directions to drive the two first rotating parts 22 to rotate counterclockwise, so that the two first rotating parts 22 hit the first partition 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.

[0067] It can be understood that the exciter 100 is defined to have a first state of clockwise rotation. In the first state, the exciter 100 is defined to have the function of controlling the two first driving members 21 to rotate forward to drive the two first rotating parts 22 to rotate clockwise so that the two first rotating parts 22 simultaneously hit the first side wall 12 and the second side wall 13 at the first position, and controlling the two first driving members 21 to rotate reversely to drive the two first rotating parts 22 to rotate counterclockwise so that the two first rotating parts 22 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 a noticeable vibration, with a clockwise rotational tactile sensation. In the second position of the first state, the housing 1 of the actuator 100 has a vibration sensation. Because the lever arm at the second position is shorter than that at the first position, the vibration sensation is relatively low.

[0068] The exciter 100 of the present invention forms an installation cavity 11 in the shell 1, so that the installation cavity 11 is used to install, fix and protect the two first rotating components 2. The shell has a first side wall 12 and a second side wall 13 arranged opposite to each other. A first partition plate 14 is provided 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. In this way, the two first rotating components 2 can be installed and fixed using the first cavity 111 and the second cavity 112 respectively, that is, one first rotating component 2 is provided in the first cavity 111, and the other first rotating component 2 is provided in the second cavity 112, and each first rotating component 2 includes a first driving member 21 and a first rotating part 22, so that the first rotating part 22 is connected to the output end of the first driving member 21 and is eccentrically arranged. In this way, by controlling the two first driving members 21 The two first rotating parts 22 are driven to rotate synchronously, so that the two first rotating parts 22 hit the first side wall 12 and the second side wall 13 at the same time, or the two first rotating parts 22 hit the first partition 14 at the same time, so that the effects of two extreme positions can be achieved, that is, when the two first rotating parts 22 hit the first side wall 12 and the second side wall 13 at the same time, torque can be generated in the rotation direction, so that the exciter 100 can generate a force sense in the rotation direction, that is, a unidirectional rotation touch is formed, and the two first rotating parts 22 hit the first partition 14 at the same time to generate forces of the same magnitude and opposite directions, thereby offsetting each other; at the same time, by setting the first rotating component 2 as the first driving member 21 to drive the rotation structure of the eccentrically arranged first rotating part 22, 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.

[0069] In this embodiment, if Figures 1 to 6 As shown, each first driving member 21 is a rotor motor, which is provided with a rotating shaft 211 , and each first rotating portion 22 is provided with an axial hole 221 . The axial hole 221 is eccentrically arranged on the first rotating portion 22 , and the rotating shaft 211 is passed through the axial hole 221 .

[0070] It is understood that the structure of the first rotating portion 22 can be regular or irregular. Optionally, the shape of the first rotating portion 22 can be circular, elliptical, square, triangular, or polygonal. The center of the shaft hole 221 and the shape of the first rotating portion 22 do not coincide. Of course, the shape of the first rotating portion 22 can also be irregular, which is not limited here.

[0071] In this embodiment, by setting the first driving member 21 as a rotor motor and using the rotor motor to drive the rotating structure of the eccentrically set first rotating part 22, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and produce a strong and clear sense of force.

[0072] It should be noted that to further ensure that the actuator 100 produces a strong and clear force sensation in the unidirectional rotation direction, the first rotating assembly 2 in the first cavity 111 and the first rotating assembly 2 in the second cavity 112 are arranged in a centrally symmetrical manner. Optionally, the two first rotating parts 22 have the same weight and the same shape and contour.

[0073] It is understandable that in order to further ensure that the actuator 100 generates a strong and clear force sensation in the unidirectional rotation direction, the driving frequencies of the two first driving members 21 are the same and the driving voltages of the two first driving members 21 are the same.

[0074] In one embodiment, each first rotating portion 22 includes at least one mass block 222. It is understood that the mass block 222 can be made of metal. Alternatively, the mass block 222 can be made of a non-metallic material.

[0075] It should be noted that in order to enable the exciter 100 to produce a strong and clear sense of force, the mass block 222 of the first rotating part 22 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 first rotating part 22 may also be provided with a counterweight block or multiple mass blocks 222 on the mass block 222. The counterweight block or multiple mass blocks 222 are located in the radial direction or circumferential direction of the rotation center of the first rotating part 22, and the shaft hole 221 is located at an eccentric position of the formed overall first rotating part 22 (that is, the shaft hole 221 does not coincide with the center of the formed overall first rotating part 22).

[0076] In this embodiment, if Figures 1 to 6 As shown, the number of mass blocks 222 of the first rotating portion 22 can be one, two, three, four, or more, and is not limited here. Among the multiple mass blocks 222, the axial hole 221 of the mass block 222 connected to the rotating shaft 211 of the first driving member 21 is located at an eccentric position of the mass block 222. In this case, another mass block 222 is connected to the mass block 222 in the radial direction or circumferential direction, and the distance between the other mass block 222 and the axial hole 221 is greater than the distance between the other mass block 222 and the center of the mass block 222.

[0077] Of course, the shaft hole 221 can also be located at the center 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 entire first rotating part 22 has an eccentric structure, which is not limited here.

[0078] Optionally, each first rotating part 22 includes three mass blocks 222, one mass block 222 is connected to the output end of a first driving member 21 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; or, the other two mass blocks 222 are connected and arranged in sequence along the circumferential direction of the mass block 222.

[0079] In one embodiment, the first partition 14 is perpendicular to the first side wall 12, and the first partition 14 is perpendicular to the second side wall 13, and the first partition 14 is located in the middle of the first side wall 12 and the second side wall 13. Figures 3 to 6 As shown, the first sidewall 12 and the second sidewall 13 of the housing 1 are optionally arranged in parallel. The first cavity 111 and the second cavity 112 of the housing 1 are arranged symmetrically with respect to the first partition 14. Furthermore, to enable the two first rotating portions 22 of the two first rotating assemblies 2 to rotate clockwise or counterclockwise in the same direction, the first rotating assemblies 2 in the first cavity 111 and the first rotating assemblies 2 in the second cavity 112 are arranged in central symmetry.

[0080] Optionally, as shown in FIG Figures 3 to 6 As shown, one first driving member 21 is arranged near the connection between the first side wall 12 and the first partition 14, and the other first driving member 21 is arranged near the connection between the second side wall 13 and the first partition 14, so that the two first driving members 21 are arranged in a centrally symmetrical manner.

[0081] 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 first rotating portion 22 is arranged in a fan shape, when the first driving member 21 drives the first rotating portion 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, and this is not limited here. It can be understood that the first side wall 12 / the second side wall 13 can be set as a two-section structure set 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 this 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, and this is not limited here.

[0082] In one embodiment, when the two first rotating parts 22 respectively hit the first side wall 12 and the second side wall 13 at the same time, 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 14 is the same as the distance from the second impact point 131 to the first partition 14.

[0083] In this embodiment, if Figure 3As shown, in order to ensure that the distances from the first impact point 121 and the second impact point 131 formed by the two first rotating parts 22 hitting the first side wall 12 and the second side wall 13 at the same time to the first partition 14 are the same, 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 first side wall 12 and the first partition 14, and the output end of the other 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 13 and the first partition 14.

[0084] In one embodiment, each first driving member 21 drives the first rotating portion 22 to rotate at an angle of 90°. When the two first driving members 21 drive the two first rotating portions 22 in a forward rotation direction, the two first rotating portions 22 simultaneously strike the first sidewall 12 and the second sidewall 13 , respectively. When the two first driving members 21 drive the two first rotating portions 22 in a reverse rotation direction, the two first rotating portions 22 simultaneously strike the first partition 14 .

[0085] In this embodiment, if Figure 1 、 Figures 3 to 6 As 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. One first driving member 21 is arranged near the connection between the first side wall 12 and the first partition 14, and the other first driving member 21 is arranged near the connection between the second side wall 13 and the first partition 14. Optionally, one first driving member 21 is located on the diagonal of the angle formed by the first side wall 12 and the first partition 14, and the other first driving member 21 is located on the diagonal of the angle formed by the second side wall 13 and the first partition 14.

[0086] It can be understood that the first rotating part 22 is located on the side of the first driving member 21 facing away from the angle formed by the first side wall 12 and the first partition 14 or the side of the angle formed by the second side wall 13 and the first partition 14, so that the first driving member 21 drives the first rotating part 22 to rotate 90°, so that the first rotating part 22 hits the first side wall 12 or the second side wall 13.

[0087] Of course, each first driving member 21 can also drive the first rotating portion 22 to rotate at an angle greater than 90° or less than 90°. It should be noted that when the line connecting the rotation axis 211 of the first driving member 21 and the center of the first rotating portion 22 is not parallel to the first side wall 12 / the second side wall 13 or the first partition 14, the angle at which the first driving member 21 drives the first rotating portion 22 to rotate can be greater than 90° or less than 90°. That is, when the two first rotating portions 22 simultaneously strike the first side wall 12 and the second side wall 13, respectively, the line connecting the rotation axis 211 of the first driving member 21 and the center of the first rotating portion 22 is not parallel to the first side wall 12 / the second side wall 13, and when the two first rotating portions 22 simultaneously strike the first partition 14, the line connecting the rotation axis 211 of the first driving member 21 and the center of the first rotating portion 22 is not parallel to the first partition 14. In this case, the angle at which the first driving member 21 drives the first rotating portion 22 to rotate can be greater than 90° or less than 90°, which is not limited here.

[0088] In this embodiment, if Figure 3 As shown, it is defined that the two first driving members 21 drive the two first rotating parts 22 to rotate in the forward direction, that is, the two first driving members 21 rotate in the forward direction, so that when the two first driving members 21 simultaneously drive the two first rotating parts 22 to rotate clockwise, the two first rotating parts 22 simultaneously hit the first side wall 12 and the second side wall 13 respectively. Figure 4 As shown, it is defined that the two first driving members 21 drive the two first rotating parts 22 to rotate in opposite directions, that is, the two first driving members 21 rotate in opposite directions, so that when the two first driving members 21 simultaneously drive the two first rotating parts 22 to rotate counterclockwise, the two first rotating parts 22 simultaneously hit the first partition 14.

[0089] In one embodiment, it is defined that when the first rotating portion 22 collides with the first side wall 12, the second side wall 13 or the first partition 14, a first impact point is formed on the first side wall 12, the second side wall 13 and the first partition 14, and each first rotating component 2 also includes a first buffer portion 23; the first buffer portion 23 is provided on the first side wall 12 and / or the second side wall 13 and / or the first partition 14, and is located at the first impact point; or, the first buffer portion 23 is provided on the first rotating portion 22, and 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.

[0090] 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.

[0091] It can be understood that when the first rotating portion 22 hits 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 coincides with the first impact point.

[0092] In this embodiment, the first buffer portion 23 can be provided on the first side wall 12 and / or the second side wall 13 and / or the first partition 14 of the housing 1, and located at the first impact point. Of course, the first buffer portion 23 can also be provided 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.

[0093] In this embodiment, the first buffer portion 23 includes multiple first buffer portions 23, each of which is disposed on the first sidewall 12, the second sidewall 13, and the first partition 14. Alternatively, the multiple first buffer portions 23 may be disposed on opposite sides of the first rotating portion 22, such that when the first rotating portion 22 strikes the first sidewall 12 / second sidewall 13, the first sidewall 12 / second sidewall 13 abuts against the first buffer portions 23, or when the first rotating portion 22 strikes the first partition 14, the first partition 14 abuts against the first buffer portions 23, etc., without limitation herein.

[0094] 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.

[0095] In this embodiment, the first driving member 21 is fixedly installed in the first cavity 111 / second cavity 112 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 an eccentric mass block that moves synchronously.

[0096] In one embodiment, the exciter 100 also includes two second rotating components 3, one second rotating component 3 is arranged in the first cavity 111 and is spaced apart from the first rotating component 2, and the other second rotating component 3 is arranged in the second cavity 112 and is spaced apart from the first rotating component 2, each second rotating component 3 includes a second driving member 31 and a second rotating part 32, the second rotating part 32 is connected to the output end of the second driving member 31 and is eccentrically arranged; wherein the two second driving members 31 synchronously drive the two second rotating parts 32 to rotate, so that the two second rotating parts 32 simultaneously hit the first partition 14 or simultaneously hit the first side wall 12 and the second side wall 13 respectively.

[0097] In this embodiment, the second rotating component 3 is respectively arranged in the first cavity 111 and the second cavity 112 of the installation cavity 11 of the shell 1, and the second rotating component 3 is arranged at intervals from the first rotating component 2, and the second rotating component 3 is set as the second driving member 31 and the second rotating part 32, so that the second rotating part 32 is connected to the output end of the second driving member 31 and is eccentrically arranged. In this way, by controlling the two second driving members 31 to synchronously drive the two second rotating parts 32 to rotate, the two second rotating parts 32 simultaneously hit the first side wall 12 and the second side wall 13, or the two second rotating parts 32 simultaneously hit the first partition 14, so that the effects of two extreme positions can be achieved, that is, when the two second rotating parts 32 hit the first side wall 12 and the second side wall 13 at the same time, torque can be generated in the rotation direction, so that the exciter 100 can generate a force sense in the rotation direction, that is, a unidirectional rotation touch is formed, and the two second rotating parts 32 simultaneously hit the first partition 14 to generate forces of the same size and opposite directions, thereby offsetting each other.

[0098] It can be understood that by setting the second rotating component 3 as a rotating structure in which the second driving member 31 drives the eccentrically arranged second rotating part 32, 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.

[0099] In one embodiment, the exciter 100 is defined as having a first state of clockwise rotation and a second state of counterclockwise rotation; in the first state, the two first driving members 21 synchronously drive the two first rotating parts 22 to rotate; in the second state, the two second driving members 31 synchronously drive the two second rotating parts 32 to rotate.

[0100] It is understood that when the actuator 100 is in a first state of clockwise rotation, the controller or control structure only controls the two first driving members 21 of the two first rotating assemblies 2 to drive the two first rotating parts 22 to rotate, and the two second driving members 31 of the two second rotating assemblies 3 are in a power-off state. When the actuator 100 is in a second state of counterclockwise rotation, the controller or control structure only controls the two second driving members 31 of the two second rotating assemblies 3 to drive the two second rotating parts 32 to rotate, and the two first driving members 21 of the two first rotating assemblies 2 are in a power-off state.

[0101] In this embodiment, in order to ensure that the controller or control structure controls the two first rotating components 2 or the two second rotating components 3 to achieve synchronous movement, in the initial state, the two first rotating components 2 are centrally symmetrically arranged in the first cavity 111 and the second cavity 112, and the two second rotating components 3 are centrally symmetrically arranged in the first cavity 111 and the second cavity 112.

[0102] In this embodiment, if Figure 5As shown, the two second driving members 31 are controlled to rotate in the forward direction to drive the two second rotating parts 32 to rotate counterclockwise, so that the two second rotating parts 32 simultaneously hit the first side wall 12 and the second side wall 13 respectively, thereby generating torque in the counterclockwise direction, so that the exciter 100 can generate a force sense in the counterclockwise direction; Figure 6 As shown, the two second driving members 31 are controlled to rotate in opposite directions to drive the two second rotating parts 32 to rotate clockwise, so that the two second rotating parts 32 hit the first partition 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.

[0103] It can be understood that the exciter 100 is defined to have a second state of counterclockwise rotation. In the second state, the exciter 100 is defined to have the function of controlling the two second driving members 31 to rotate forward to drive the two second rotating parts 32 to rotate counterclockwise, so that the two second rotating parts 32 simultaneously hit the first position of the first side wall 12 and the second side wall 13 respectively, and controlling the two second driving members 31 to rotate reversely to drive the two second rotating parts 32 to rotate clockwise, so that the two second rotating parts 32 simultaneously hit the second position of the first partition 14.

[0104] Optionally, the structure of the first rotating assembly 2 is the same as that of the second rotating assembly 3. Figures 1 to 6 As shown, each second driving member 31 is a rotor motor, which is provided with a rotating shaft 211 , and each second rotating portion 32 is provided with a shaft hole 221 . The shaft hole 221 is eccentrically arranged on the second rotating portion 32 , and the rotating shaft 211 is passed through the shaft hole 221 .

[0105] It is understood that the second rotating portion 32 can have a regular or irregular shape. Alternatively, the second rotating portion 32 can have a circular, elliptical, square, triangular, or polygonal shape. The center of the shaft hole 221 and the second rotating portion 32 do not coincide. Of course, the shape of the second rotating portion 32 can also be irregular, and this is not limited here.

[0106] In this embodiment, by setting the second driving member 31 as a rotor motor and using the rotor motor to drive the rotating structure of the eccentrically set second rotating part 32, not only the structure of the exciter 100 is effectively simplified, but also the exciter 100 can achieve high-speed continuous action and produce a strong and clear sense of force.

[0107] It should be noted that to further ensure that the actuator 100 produces a strong and clear force sensation in the unidirectional rotation direction, the second rotating assembly 3 in the first cavity 111 and the second rotating assembly 3 in the second cavity 112 are centrally symmetrically arranged. Optionally, the two second rotating parts 32 have the same weight and the same shape and contour.

[0108] It is understandable that in order to further ensure that the actuator 100 generates a strong and clear force sensation in the unidirectional rotation direction, the driving frequencies of the two second driving members 31 are the same and the driving voltages of the two second driving members 31 are the same.

[0109] In one embodiment, each second rotating portion 32 includes at least one mass block 222. It is understood that the mass block 222 can be made of metal. Alternatively, the mass block 222 can be made of a non-metallic material.

[0110] It should be noted that in order to enable the exciter 100 to produce a strong and clear sense of force, the mass block 222 of the second rotating part 32 adopts a relatively heavy structure. Optionally, the mass block 222 is made of metal. In order to further improve the mass of the second rotating part 32, the second rotating part 32 may also be provided with a counterweight block or multiple mass blocks 222 on the mass block 222. The counterweight block or multiple mass blocks 222 are located in the radial direction or circumferential direction of the rotation center of the second rotating part 32, and the shaft hole 221 is located at an eccentric position of the formed overall second rotating part 32 (that is, the shaft hole 221 does not coincide with the center of the formed overall second rotating part 32).

[0111] In this embodiment, if Figures 1 to 6 As shown, the number of mass blocks 222 of the second rotating portion 32 can be one, two, three, four, or more, and is not limited here. Among the multiple mass blocks 222, the axial hole 221 of the mass block 222 connected to the rotating shaft 211 of the second driving member 31 is located at an eccentric position of the mass block 222. In this case, another mass block 222 is connected to the mass block 222 in the radial direction or circumferential direction, and the distance between the other mass block 222 and the axial hole 221 is greater than the distance between the other mass block 222 and the center of the mass block 222.

[0112] Of course, the shaft hole 221 can also be located at the center 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 entire second rotating part 32 has an eccentric structure, which is not limited here.

[0113] Optionally, each second rotating part 32 includes three mass blocks 222, one mass block 222 is connected to the output end of a second driving member 31 and is eccentrically arranged; the other two mass blocks 222 are connected and arranged in sequence along the radial direction of the second rotating part 32; or, the other two mass blocks 222 are connected and arranged in sequence along the circumferential direction of the mass block 222.

[0114] In one embodiment, if Figures 3 to 6 As shown, the first partition plate 14 is perpendicular to the first side wall 12 , the first partition plate 14 is perpendicular 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 .

[0115] It is understandable, as shown in the figure Figures 3 to 6 As shown, the first sidewall 12 and the second sidewall 13 of the housing 1 are optionally arranged in parallel. The first cavity 111 and the second cavity 112 of the housing 1 are arranged symmetrically with respect to the first partition 14. At the same time, in order to achieve the same clockwise or counterclockwise rotation of the two second rotating parts 32 of the two second rotating assemblies 3, the second rotating assembly 3 in the first cavity 111 and the second rotating assembly 3 in the second cavity 112 are arranged in a centrally symmetrical manner.

[0116] Optionally, as shown in FIG Figures 3 to 6 As shown, one second driving member 31 is arranged near the connection between the first side wall 12 and the first partition 14, and another second driving member 31 is arranged near the connection between the second side wall 13 and the first partition 14, so that the two second driving members 31 are arranged in a centrally symmetrical manner.

[0117] Optionally, the first driving member 21 and the second driving member 31 in the first cavity 111 are symmetrically arranged relative to the perpendicular midline of the first partition 14. The first driving member 21 and the second driving member 31 in the second cavity 112 are symmetrically arranged relative to the perpendicular midline of the first partition 14.

[0118] In one embodiment, when the two second rotating parts 32 collide with the first side wall 12 and the second side wall 13 respectively at the same time, the two second rotating parts 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 14 is the same as the distance from the fourth impact point 132 to the first partition 14.

[0119] In this embodiment, if Figure 5As shown, in order to ensure that the two second rotating parts 32 simultaneously hit the first side wall 12 and the second side wall 13 to form the third impact point 122 and the fourth impact point 132 with 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 second driving member 31 (that is, the rotation center of the second rotating part 32) is located on the angular bisector of the angle formed by the first side wall 12 and the first partition 14, and the output end of the other second driving member 31 (that is, the rotation center of the second rotating part 32) is located on the angular bisector of the angle formed by the second side wall 13 and the first partition 14.

[0120] 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 first side wall 12, and when the second rotating part 32 hits the first side wall 12, the second rotating part 32 forms a second impact point on the first side wall 12. The distance from the first impact point to the first partition 14 is the same as the distance from the second impact point to the first partition 14.

[0121] It can be understood that the shape and outline of the first rotating portion 22 are the same as the shape and outline of the second rotating portion 32 , that is, the structure of the first rotating component 2 is the same as the structure of the second rotating component 3 .

[0122] In one embodiment, each second driving member 31 drives the second rotating portion 32 to rotate 90°. When the two second driving members 31 drive the two second rotating portions 32 to rotate forward, the two second rotating portions 32 simultaneously strike the first sidewall 12 and the second sidewall 13 , respectively. When the two second driving members 31 drive the two second rotating portions 32 to rotate backward, the two second rotating portions 32 simultaneously strike the first partition 14 .

[0123] In this embodiment, if Figure 1 、 Figures 3 to 6 As 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. A second driving member 31 is arranged near the connection between the first side wall 12 and the first partition 14, and another second driving member 31 is arranged near the connection between the second side wall 13 and the first partition 14. Optionally, one second driving member 31 is located on the diagonal of the angle formed by the first side wall 12 and the first partition 14, and the other second driving member 31 is located on the diagonal of the angle formed by the second side wall 13 and the first partition 14.

[0124] It can be understood that the second rotating part 32 is located on the side of the second driving member 31 facing away from the angle formed by the first side wall 12 and the first partition 14 or the side of the angle formed by the second side wall 13 and the first partition 14, so that the second driving member 31 drives the second rotating part 32 to rotate 90°, so that the second rotating part 32 hits the first side wall 12 or the second side wall 13.

[0125] Of course, the angle at which each second driving member 31 drives the second rotating portion 32 to rotate may also be greater than 90° or less than 90°. It should be noted that when the line connecting the rotation axis 211 of the second driving member 31 and the center of the second rotating portion 32 is not parallel to the first side wall 12 / the second side wall 13 or the first partition 14, the angle at which the second driving member 31 drives the second rotating portion 32 to rotate may be greater than 90° or less than 90°. That is, when the two second rotating portions 32 simultaneously strike the first side wall 12 and the second side wall 13, respectively, the line connecting the rotation axis 211 of the second driving member 31 and the center of the second rotating portion 32 is not parallel to the first side wall 12 / the second side wall 13, and when the two second rotating portions 32 simultaneously strike the first partition 14, the line connecting the rotation axis 211 of the second driving member 31 and the center of the second rotating portion 32 is not parallel to the first partition 14. In this case, the angle at which the second driving member 31 drives the second rotating portion 32 to rotate may be greater than 90° or less than 90°, which is not limited here.

[0126] In this embodiment, if Figure 5 As shown, it is defined that the two second driving members 31 drive the two second rotating parts 32 to rotate in the forward direction, that is, the two second driving members 31 rotate in the forward direction, so that when the two second driving members 31 simultaneously drive the two second rotating parts 32 to rotate counterclockwise, the two second rotating parts 32 simultaneously hit the first side wall 12 and the second side wall 13 respectively. Figure 6 As shown, it is defined that the two second driving members 31 drive the two second rotating parts 32 to rotate in the opposite direction, that is, the two second driving members 31 rotate in the opposite direction, so that when the two second driving members 31 simultaneously drive the two second rotating parts 32 to rotate clockwise, the two second rotating parts 32 simultaneously hit the first partition 14.

[0127] In one embodiment, it is defined that when the second rotating portion 32 collides with the first side wall 12, the second side wall 13 or the first partition 14, a second impact point is formed on the first side wall 12, the second side wall 13 and the first partition 14, and each second rotating component 3 also includes a second buffer portion 33; the second buffer portion 33 is provided on the first side wall 12 and / or the second side wall 13 and / or the first partition 14, and is located at the second impact point; or, the second buffer portion 33 is provided 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.

[0128] In this embodiment, if Figures 1 to 6As 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 the second buffer portion 33 also has a noise reduction effect.

[0129] It can be understood that when the second rotating portion 32 hits 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 coincides with the second impact point.

[0130] In this embodiment, the second buffer portion 33 can be provided on the first side wall 12 and / or the second side wall 13 and / or the first partition 14 of the housing 1 and located at the first impact point. Of course, the second buffer portion 33 can also be provided 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.

[0131] In this embodiment, the second buffering portion 33 includes multiple second buffering portions 33, each of which is disposed on the first sidewall 12, the second sidewall 13, and the first partition 14. Alternatively, the multiple second buffering portions 33 may be disposed on opposite sides of the second rotating portion 32, such that when the second rotating portion 32 strikes the first sidewall 12 / second sidewall 13, the first sidewall 12 / second sidewall 13 abuts the second buffering portions 33, or when the second rotating portion 32 strikes the first partition 14, the first partition 14 abuts the second buffering portions 33, etc., without limitation herein.

[0132] 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.

[0133] In this embodiment, the second driving member 31 is fixedly installed in the first cavity 111 / second cavity 112 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 an eccentric mass block that moves synchronously.

[0134] As can be understood, when the rotor motor is driven, the first rotating portion 22 / second rotating portion 32 rapidly rotates around the rotor motor's rotation axis 211. When the first rotating portion 22 / second rotating portion 32 reaches its two extreme motion positions, they collide with the corresponding first sidewall 12 and second sidewall 13 of the housing 1, respectively. When the first rotating portion 22 / second rotating portion 32 collides with the housing 1, a rapid braking effect is generated, and a corresponding impact tactile sensation is felt on the housing 1. By driving multiple rotor motors in combination, two extreme state effects can be achieved: a unidirectional rotational tactile sensation on one side and a unidirectional rotational tactile sensation on the other side. The magnitude of the rotational tactile sensation on each side is related to the product of the corresponding force and the lever arm. Furthermore, long-term, high-frequency driving can produce rapid, multiple-frequency unidirectional rotational tactile sensations on the same coordinate axis: clockwise rotation and counterclockwise rotation.

[0135] It should be noted that when the first rotating part 22 / the second rotating part 32 moves 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 achieving a pure rotating tactile effect.

[0136] Of course, in actual use, the two limits of the same rotation can be used in combination, or one set of force arms can be made longer according to the split of the structure to obtain better tactile feedback. There is no limitation here.
