Description

Technical Field

[0001] The present invention relates to the technical field of vibration devices, and particularly to drive exciters and electronic devices.

Background Art

[0002] Currently, as a means of reproducing a sense of force, there is a method of inputting an asymmetric signal into a linear resonator and using the human sense to create an illusion of a force acting "as if it is going in a certain direction". In principle, the above method can only generate a continuous directional sense of force, cannot achieve a discrete output, and the range of force sense change is not large. Since the asymmetric signal generates extra vibrations and cannot generate a pure directional output, the sense of direction of the vibrations obtained by the above method is blurred and the efficiency is low.

[0003] In addition, a linear resonator or exciter adopting the above method still performs braking and resetting using a damping material such as a spring, that is, realizes the above functions in the form of solid contact. When using the solid contact type, a steep reaction force is generated during contact. Therefore, if the elasticity of the material is strong, repulsion occurs, and at this time, the mass point vibrates without anisotropy. If the damping characteristics of the material are too large, the kinetic energy of the braked mass point changes into thermal energy, the energy loss increases, and the efficiency decreases. Furthermore, wear and deformation of the contact surface are inevitable, and the long-term stability of the structure cannot be guaranteed.

[0004] The above content is only used to assist the understanding of the technical solution of the present invention, and does not represent an admission that the above content is the prior art.

[0014] In one embodiment, the guide structure includes at least two guide bars extending along the vibrating direction of the vibrator, and the ends of the guide bars are fixed to the fixture.

[0021] The realization of the object, functional features and advantages of the present invention will be further described by combining the embodiments and referring to the accompanying drawings.

Modes for Carrying Out the Invention

[0022] The following clearly and completely describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative positional relationship and movement between components in a specific posture (as shown in the drawings). When the specific posture changes, the directional indications also change accordingly.

[0024] In addition, the descriptions related to "first", "second", etc. in the present invention are only used for the purpose of description, and should not be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Thus, the features limited to "first" and "second" can explicitly or implicitly include at least one of the features. Also, the technical solutions between the embodiments can be combined with each other, but it must be based on what can be realized by those skilled in the art. If there is a contradiction or inability to realize in the combination of technical solutions, such a combination of technical solutions should be considered non-existent and not included in the protection scope required by the present invention.

[0025] "Anisotropic vibration", also called "asymmetric vibration", can be realized by inputting an asymmetric signal into a vibration device such as a vibration motor, etc., and generating a feeling of pulling in a certain direction for the user holding the vibration device. The vibration device that can realize anisotropic vibration is often used in devices such as game controllers, and provides good feedback to the user through asymmetric vibration.

[0026] In the vibration device according to the technical solution of the present application, the so-called "discrete" is a concept relative to "continuous". For example, after one excitation, the vibration motor continuously outputs vibration to the vibration device, causing the user to feel a continuous vibration sensation or a tensile sensation for a certain period of time, resulting in continuous vibration. On the other hand, if the vibration device outputs vibration in a clear direction at intervals within a certain period of time once or multiple times, it will be discrete anisotropic vibration.

[0027] As shown in FIG. 8, both of the two figures in FIG. 8 show that the waveform is repeated at a certain period. This is because a pseudo-force sense effect of "pulling in a certain direction" is generated by an asymmetric waveform that is repeated at a certain period. The waveform has a lot of unnecessary vibrations in addition to the part that contributes to the generation of the force sense and is not suitable for the generation of discrete force sense.

[0028] Referring to FIGS. 1 to 12, in order to discretely present anisotropic vibration and at the same time achieve the purpose of improving the efficiency of the drive exciter 100 and reducing hardware loss, the drive exciter 100 proposed by the present invention includes a bracket 10 including a fixture 11 and a guide structure 13 connected to the fixture 11, a vibration part 30 movably connected to the guide structure 13 and provided with a vibrator 33 capable of vibrating, a braking part 40 provided opposite to each other and including a first end 41 connected to the vibration part 30 and a second end 42 connected to the fixture 11, and a locking part 50 including a driver 51 connected to the fixture 11 and a locking material 53 connected to the output end of the driver 51. The drive exciter 100 has a first state in which the locking material 53 is in contact with the vibration part 30 and a second state in which the locking material 53 is detached from the vibration part 30. In the second state, the vibration part 30 moves toward the fixture 11, and the first end 41 and the second end 42 interact with each other to space the first end 41 and the second end 42 apart.

[0029] In one embodiment, the fixture 11 is substantially in the shape of a plate, and the guide structure 13 is provided on one side of the fixture 11 and fixedly connected to the fixture 11. The vibrating part 30 may be a linear resonator. The vibrating part 30 is movably fitted and connected to the guide structure 13. The guide structure 13 may be provided around the braking part 40 or may be provided on one side of the guide part, and is not limited herein. Optionally, the guide structure 13 may be one or more guide bars 131 connected to the fixture 11. The vibrating part 30 is fitted into the guide bar 131, and a rail groove may be provided in the guide structure 13, and the vibrating part 30 is slidably provided in the rail groove. A vibrator 33 that vibrates along a certain direction in the vibrating part 30 is provided. As can be understood, the vibrator 33 has a certain mass so as to have sufficient energy during vibration.

[0030] In this embodiment, the locking part 50 is provided on one side of the vibrating part 30. Here, the driver 51 may be a driving device such as a linear motor, a solenoid, a linear motor, and a rotary motor. The driver 51 drives the locking material 53 to move forward or rotate relative to the vibrating part 30 so as to approach or separate.

[0031] The braking part 40 may be a magnet provided separately or an integral air spring, and brakes the vibrating part 30 by the interaction between the first end 41 and the second end 42.

[0032] Specifically, in one embodiment, the following steps are required for the driving exciter 100 to generate one complete anisotropic vibration: Energy storage stage: An electric driving signal is input into the vibrating part 30, an exciting magnetic field is generated in the vibrating cavity, and the driving vibrator 33 continuously vibrates to store energy. At this time, the driving exciter 100 is in the first state, and the locking material 53 is abutted against the side surface of the vibrating part 30 to relatively fix the vibrating part 30 in the vibrating direction of the vibrator 33. Release stage: The driver 51 drives the locking material 53 to move forward or rotate until the locking material 53 disengages from the vibrating part 30, and the driving exciter 100 is transitioned to the second state. Moving stage: The drive exciter 100 is in the second state, the vibrating part 30 is released from the restraint of the locking material 53, and by driving the internal vibrator 33, the fixture 11 moves to the braking part 40 where it is provided. Braking stage: As the vibrating part 30 moves, the distance between the first end 41 and the second end 42 gradually decreases, and the interaction between the two also increases. The amount of movement of the vibrating part 30 is transmitted to the fixture 11 as acceleration, generating anisotropic vibration and generating a tensile or force feeling along the normal direction of the contact surface between the two. Return stage: After one anisotropic vibration occurs, the vibrating part 30 leaves the fixture 11, the drive exciter 100 returns to the first state and waits for the next trigger, and the anisotropic vibration stops.

[0033] As can be understood, in the above embodiment, the generation of anisotropic vibration is not due to the vibration of the vibrating part 30 itself, but is caused by the fitting between the braking part 40 and the vibrating part 30. That is, the braking part 40 brakes the vibrating part 30 to generate anisotropic vibration, the vibrating part 30 leaves the fixture 11 and returns to the first state, and the anisotropic vibration stops.

[0034] After going through the above several stages, the drive exciter 100 can generate one anisotropic vibration. By circulating the above process multiple times within a certain period of time, multiple anisotropic vibrations can be discretely generated. Furthermore, by controlling the movement frequency of the vibrating part 30, the frequency at which anisotropic vibration occurs can be controlled, and by changing parameters such as the mass or current magnitude of the vibrating part 30, the magnitude of the anisotropic vibration can be changed.

[0035] The technical solution of the present application can greatly expand the asymmetry of anisotropic vibration and can discretely present asymmetric vibration in a short time. By generating vibration close to the actually occurring asymmetric vibration force, a clear force feeling in a certain direction can be discretely presented in a short time. Since the direction of this force feeling depends on the contact direction between the braking part 40 and the vibrator 30, it is no longer limited to the gripping method.

[0036] In the present application, the braking of the vibrating part 30 is realized by the interaction between the first end portion 41 and the second end portion 42, anisotropic vibration occurs, the vibrating part 30 and the fixture 11 do not come into contact, and hardware loss is reduced. On the other hand, solid contact type braking tends to be short in time. In the present application, by changing parameters such as the materials and shapes of the first end portion 41 and the second end portion 42, a longer braking time is realized, various effects are realized, a clear directional force feeling is presented, and there is almost no unnecessary vibration.

[0037] Referring to FIGS. 6 and 7, in one embodiment, the first end portion 41 is a first magnetic material, the second end portion 42 is a second magnetic material, and the polarities of the sides where the first magnetic material and the second magnetic material face each other are opposite. In this embodiment, braking on the vibrating part 30 is realized by the repulsive force between the first magnetic material and the second magnetic material. Referring to the drawings in combination, compared with solid materials, when the distance between the first magnetic material and the second magnetic material becomes smaller, the repulsive force between the first magnetic material and the second magnetic material increases exponentially, and although they do not come into contact, it can be easily understood that the directionality of the generated anisotropic vibration becomes clearer.

[0038] In addition, referring to FIGS. 10, 11, and 12 for comparison, vibrations caused by solid contact tend to be intense and short, while vibrations caused by magnetic pole repulsion have regular modes, clear directions, and long times.

[0039] Comparing FIGS. 11 and 12, the vibration time becomes longer after the dimensions of the first magnetic material and the second magnetic material are exchanged, and different effects occur.

[0040] Also, both the first magnetic material and the second magnetic material may be permanent magnets, and of course, both may be electromagnets, and are not limited here.

[0041] Referring to FIG. 7, in one embodiment, a boss is provided on the surface of the vibrating part 30, a first magnetic material is provided on the boss, a yoke material 43 connected to the fixture 11 is further provided on the braking part 40, a flux barrier is provided on the yoke material 43, and a second magnetic material is provided within the flux barrier. In this way, magnetic flux leakage and the reinforcing magnetic field can be reduced, a better braking effect can be obtained, and the utilization rate can be improved.

[0042] In an embodiment of another aspect of the present application, the braking part 40 is an air spring whose both ends respectively form a first end part 41 and a second end part 42. As the first end part 41 approaches the second end part 42, as the distance decreases, the space within the air spring becomes smaller and smaller, the air density increases, and accordingly the pressure also increases. While ensuring that the first end part 41 and the second end part 42 do not come into contact, a good vibration effect can be obtained.

[0043] Furthermore, referring to FIG. 5, in an embodiment of the present invention, the fixture 11 includes a mounting body 111 provided with a mounting groove and a through hole 111a provided on the bottom wall of the mounting groove, and a cover plate 113. A guide structure 13 is connected to the mounting body 111, the cover plate 113 seals the groove opening of the mounting groove, and is removably connected to the mounting body 111. The second end part 42 is fixedly connected to the cover plate 113 through the through hole 111a. The cover plate 113 is bolt-connected to the mounting body 111, and the second end part 42 is adhesively or bolt-connected to the cover plate 113. In this embodiment, by removing the cover plate 113, the protection of the braking part 40 or the maintenance of the equipment can be easily and quickly realized.

[0044] Referring to the figure, in an embodiment of the present invention, the locking part 50 includes two locking members 53 located on both sides of the vibrating part 30 to form a position regulation space. The mover 51 is connected to at least one locking member 53. Here, in the first state, the vibrating part 30 is position-regulated within the position regulation space.

[0045] In this embodiment, the locking member 53 may be a block-shaped body or a rod-shaped body. The vibration direction of the vibration member 33 is the left-right direction. Optionally, the braking unit 40 is provided on the right side of the vibrator 33, and two locking members 53 are provided at a left-right interval so as to form the vibration space. Here, the left locking member 53 is fixed, the driver 51 is connected to the right locking member 53, and the locking member 53 is driven to rotate or translate, so as to switch the drive exciter 100 between the first state and the second state.

[0046] Specifically, in one embodiment of the present invention, a rotating shaft is provided on the driver 51. The locking member 53 is a locking bar. One end of the locking member 53 is connected to the rotating shaft, and the longitudinal direction of the locking member 53 and the extending direction of the rotating shaft are provided at an angle. In this embodiment, the driver 51 is a rotating motor, the locking member 53 is a substantially L-shaped structure, one side of the locking member 53 is connected to the rotating shaft, and the rotating shaft rotates to make the other side of the locking member 53 approach or move away from the vibrating portion 30. When the driver 51 receives a predetermined signal, the rotating shaft drives the locking member 53 to rotate until the locking member 53 abuts against the housing of the vibrating portion 30 or the locking member 53 disengages from the vibrating portion 30. In this way, the movement of the lock 53 and the switching between the first state and the second state can be easily and simply realized.

[0047] In an embodiment of another aspect of the present invention, the driver 51 drives the locking member 53 to move linearly, and the moving direction of the locking member 53 and the vibration direction of the vibrator 33 are provided at an angle. Optionally, the driver 51 may be a linear motor. The driver 51 includes a stator fixed to the bracket 10 and a mover that slidably engages with the stator and moves along a straight line. The locking member 53 is connected to the mover. Preferably, the straight line in which the moving direction of the locking member 53 is located and the straight line in which the vibration direction of the vibrator 33 is located are provided at a 90-degree angle. In this way, the structure is simple and effective, and the generation and transmission of vibration are also relatively clear, having a good effect.

[0048] Of course, the drive member 51 may have other structural forms capable of realizing the above technical concept, and is not particularly limited herein. Accordingly, the structure of the locking member 53 may be changed according to the form and spatial arrangement of the drive member 51 and is not limited.

[0049] Referring to FIG. 1, in one embodiment of the present invention, the bracket 10 further includes a first connection frame 15 provided in parallel with the guide structure 13. The first connection frame 15 is connected to the fixture 11, and the driver 51 is fixed to the first connection frame 15. The locking portion 50 further includes a stopper 55 connected to the first connection frame 15 to form a position regulating groove 55a. A notch 55b directed toward the vibrating portion 30 is formed in the side wall of the position regulating groove 55a. One end of the locking member 53 connected to the driver 51 enters the position regulating groove 55a, and one end of the locking member 53 away from the driver 51 protrudes from the notch 55b. The locking member 53 rotates between two opposing side walls of the notch 55b.

[0050] In this embodiment, the first connection frame 15 is bolt-connected to the surface of the fixture 11 and has a longitudinal direction. The longitudinal direction of the first connection frame 15 is provided parallel to the vibration direction of the vibrator 33. The stopper 55, the locking member 53, and the driver 51 are all connected to the side surface of the first connection frame 15. Further, the first connection frame 1515 is partially embossed to ensure structural weight reduction and vibration effect.

[0051] In this embodiment, the stopper 55 has a structure like a cap with an unrestricted shape, and the groove opening of the position regulating groove 55a faces the locking material 53. A plurality of notches 55b are provided on the groove wall of the position regulating groove 55a. The driver 51 is a rotary motor. A part of the locking material 53 is provided in the position regulating groove 55a, and a part thereof penetrates through the notch 55b and protrudes from the position regulating groove 55a. As can be understood, the driver 51 can rotationally drive the locking material 53 into the space between the both side walls of the notch 55b. When the locking material 53 abuts against one of its side walls, the locking material 53 also just abuts against the vibrating part 30. When the locking material 53 abuts against the other side wall, the locking material 53 disengages from the vibrating part 30. Adding the stopper 55 to limit the movement range of the locking material 53 is advantageous for offsetting the inertia of the locking material 53 to a certain extent, and improving the operating efficiency and stability of the locking material 53.

[0052] Referring to FIGS. 1, 3 and 4, in an embodiment of the present invention, the guide structure 13 includes at least two guide bars 131 extending along the vibration direction of the vibrator 33, and the ends of the guide bars 131 are fixed to the fixture 11.

[0053] The vibrating part 30 includes a housing 31 provided with a sleeve 311 movably fitted to the guide bar 131 on the side surface to surround the vibration space, a vibrator 33 provided vibratably in the vibration space, and two spring pieces 37 provided on both sides of the vibrator 33 along the vibration direction of the vibrator 33 to connect the housing 31 and the ends of the vibrator 33.

[0054] In this embodiment, the housing 31 includes two end caps provided oppositely and a connecting plate provided between the two end caps. Two mounting ears are respectively provided on both sides of each end cap. A retracting hole through which the guide bar 131 penetrates is provided in the mounting ear. The mounting ears between the two end caps are provided oppositely and are connected by the sleeve 311.

[0055] The vibrator 33 vibrates along a direction within the vibration space. The vibrator 33 drives and vibrates the spring piece 37 simultaneously with the vibration, stores the generated energy in the spring piece 37, and when the housing 31 approaches the fixture 11, the first end 41 and the second end 42 interact, and the stored energy is released in an acceleration manner to generate a vibration wave. Since the vibrating part 30 approaches the fixture 11 from one side, the generated vibration is also on one side and has an obvious asymmetry. That is, the sense of tension in a certain direction is real and does not depend on the user's gripping method or sensory experience.

[0056] Furthermore, referring to FIG. 4, in one embodiment of the present invention, the vibrating part 30 further includes a first link plate 34 and a second link plate 35 that are provided opposite to each other and fixedly connected to the housing 31. One end of the spring piece 37 is connected to the first link plate 34 or the second link plate 35, and the other end is connected to the end of the vibrator 33. Optionally, the cross-section of the vibrator 33 in this embodiment is a substantially parallelogram, with its vibration direction being the left-right direction and the up-down direction perpendicular to the left-right direction located within the plane of the paper. The first link plate 34 is provided above, the second link plate 35 is provided below, the upper left end of the vibrator 33 is connected to the second link plate 35, and the lower right end of the vibrator 33 is connected to the first link plate 34. When the vibrator 33 vibrates, its end vibrates the spring piece 37. By providing it in this way, the elasticity of the spring piece 37 can be better utilized, and the amplitudes of the vibrator 33 and the spring piece 37 can be increased equally.

[0057] Referring to FIG. 1, in one embodiment of the present invention, the drive exciter 100 further includes a reset member 60 that is a spring with both ends elastically connected to the surface of the vibrating part 30 and the fixture 11. By providing the reset member 60, the vibrating part 30 can be smoothly reset after the braking stage, thereby restoring the drive exciter 100 to the first state.

[0058] Of course, the reset member 60 is not limited to a spring, and other structures that can reset the vibrating part 30 may also be used.

[0059] In another embodiment of the present invention, the drive exciter 100 includes two fixtures 11 provided opposite to each other, two braking parts 40, and two locking parts 50. Both ends of the guide structure 13 are connected to the two fixtures 11. The two braking parts 40 are provided opposite to the two fixtures 11. The two locking parts 50 are provided in parallel on both sides of the vibrating part 30. One driver 51 is connected to one locking material 53. Each locking material 53 is provided between the vibrating part 30 and the fixture 11 to form a position regulating space. Here, in the first state, the vibrating part 30 is position-regulated within the position regulating space.

[0060] In this embodiment, the two locking materials 53 may be provided on the same side or on different sides. Moreover, the two locking materials 53 are movable. However, in the second state, only one of the locking materials 53 moves away from the vibrating part 30. For example, when the right locking material 53 moves, the left locking material 53 is fixed, and the vibrating part 30 moves to the right. When the left locking material 53 moves, the right locking material 53 is fixed, and the vibrating part 30 moves to the left. That is, in the second state, the vibrating part 30 can approach only one of the braking parts 40, and the anisotropic vibrations generated when the vibrating part 30 fits into the two braking parts 40 respectively are reversed. In this embodiment, the drive exciter 100 can realize the movement of the vibrating part 30 in different directions, and can further present two anisotropic vibrations in opposite directions. It should be noted that the above two vibrations do not exist simultaneously.
