The driving exciter has a first state in which the locking material is in contact with the vibrating part and a second state in which the locking material is detached from the vibrating part. In the second state, the vibrating part moves toward the braking part and is in contact with the braking part. The technical solution of the present application can expand the asymmetry of anisotropic vibration and generate vibration close to the actually generated asymmetric vibration force, so as to discretely present a clear sense of force in a certain direction in a short time.

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] Conventional vibration devices constantly produce asymmetric vibrations to create the illusion of a force acting "as if in a certain direction." However, to cause such an illusion, not only is the gripping method of the device limited by shearing the skin, but it is also necessary to limit the vibration frequency to a range where it is easy to perceive, and the stimulus must be sustained for a certain period of time.

[0003] As a means of reproducing the sense of force, there is currently a method of inputting an asymmetric signal into a linear resonator and creating an illusion using the human sense. In principle, this method can only generate a continuous directional sense of force and cannot achieve discrete vibration output. The equivalent force felt by this method is small, and the asymmetric signal also generates extra vibrations, making it difficult to obtain a clear sense of direction.

[0004] From the above, conventional vibration devices have many limitations that are not limited to the above problems in actual applications.

In the second state, the vibrating part moves toward the braking part and abuts against the braking part.

[0007] In one embodiment of the present invention, the locking part includes two locking members that are located on both sides of the vibrating part and form a position regulating space, and the rotor is connected to at least one of the locking members. Here, in the first state, the vibrating part is position-regulated within the position regulating space.

[0008] In one embodiment of the present invention, a rotating shaft is provided on the rotor, the locking member is a locking bar, one end of the locking member is connected to the rotating shaft, and the longitudinal direction of the locking member and the extending direction of the rotating shaft are provided to form an angle.

[0009] In one embodiment of the present invention, the bracket further includes a first connection frame provided in parallel with the guide structure, the first connection frame is connected to the fixture, and the rotor is fixed to the first connection frame. The locking part further includes a stopper connected to the first connection frame and forming a position regulating groove. Notches facing the vibrating part are formed on side walls of the position regulating groove. One end of the locking member connected to the rotor enters the position regulating groove, and one end of the locking member away from the rotor protrudes from the notch. The locking member rotates and moves between two opposing side walls of the notch.

[0010] In one embodiment of the present invention, the guide structure includes at least two guide bars extending along the vibration direction of the vibrator, and ends of the guide bars are fixed to the fixture. The vibrating part is On the side, there is a housing that surrounds the vibration space and is provided with a sleeve movably fitted to the guide bar, a vibrator provided vibratably within the vibration space, and two elastic members provided on both sides of the vibrator along the vibration direction of the vibrator, connecting the housing and the end of the vibrator.

[0011] In one embodiment of the present invention, the vibration part further includes a first link plate and a second link plate that are provided opposite to each other and fixedly connected to the housing. The elastic member is a spring piece having one end connected to the first link plate or the second link plate and the other end connected to the end of the vibrator. And / or, a buffer material towards the braking part is provided at the end of the housing along the vibration direction of the vibrator.

Advantages of the Invention

[0016] The technical solution of the present application is to switch the drive exciter between a first state and a second state by a lock member provided movably. In the first state, the vibrating part is relatively fixed. In the second state, the vibrating part is brought into contact with the braking part, and the braking part brakes the vibrating part to generate anisotropic vibration. Since the generation of the anisotropic vibration requires the fitting of the braking part and the vibrating part, the frequency at which vibration occurs depends on the frequency at which the vibrating part moves and comes into contact with the braking part. Therefore, when the lock member continuously moves and continuously switches between the first state and the second state, the vibrating part is intermittently brought into contact with the braking part, so that anisotropic vibration can be generated discretely.

[0017] The technical solution of the present application can greatly expand the asymmetry of the anisotropic vibration and discretely present the asymmetric vibration in a short time. By generating vibration close to the actually generated asymmetric vibration force, a clear sense of force in a certain direction can be discretely presented in a short time. Since the direction of this sense of force depends on the contact direction between the braking part and the vibrator, it is not limited to the gripping method.

Modes for Carrying Out the Invention

[0020] The following will clearly and completely describe 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. All other embodiments obtained by those skilled in the art on the premise of not paying creative labor based on the embodiments in the present invention shall fall within the protection scope of the present invention.

[0021] 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 parts in a specific posture (as shown in the drawings). When the specific posture changes, the directional indications also change accordingly.

[0022] In addition, in the present invention, descriptions such as "first", "second", etc. 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, features limited to "first" and "second" can explicitly or implicitly include at least one such feature. Also, the technical solutions between each embodiment can be combined with each other, but it must be based on what those skilled in the art can achieve. If contradictions occur in the combination of technical solutions or they cannot be realized, it should be considered that such a combination of technical solutions does not exist and is not included in the protection scope required by the present invention.

[0023] "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 pulling feeling in a certain direction for the user holding the vibration device. A vibration device capable of realizing anisotropic vibration is often used in devices such as game controllers, and provides good feedback to the user through asymmetric vibration.

[0024] 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 continuous vibration to the vibration device, making the user feel a continuous vibration feeling or pulling feeling 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 becomes discrete anisotropic vibration.

[0025] In addition, since the equivalent force of conventional vibration devices is small, users can surely feel the vibration, and in order to generate a pulling feeling, it is often necessary to continuously output vibration within a certain frequency range. Elastic pieces are connected to both ends of the vibrator of the vibration motor, and even with only one excitation, after a relatively strong vibration of the vibrator once, aftershock occurs in the vibration motor due to the action of the elastic pieces.

[0026] As shown in FIG. 11, both of the two figures in FIG. 11 show that the waveforms are 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 constant period, and the waveforms have a lot of unnecessary vibrations in addition to the parts that contribute to the generation of the force sense, and are not suitable for the generation of discrete force sense.

[0027] Referring to FIGS. 1 to 10, in order to achieve the purpose of discretely presenting distinct anisotropic vibrations, the driving 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 vibrating portion 30 movably connected to the guide structure 13 and provided with a vibrator 33 capable of vibrating, a braking portion 40 connected to the fixture 11 and provided toward the vibrating portion 30, and a locking portion 50 including a driver 51 connected to the fixture 11 and a locking member 53 connected to the output end of the driver 51. The driving exciter 100 has a first state in which the locking member 53 is in contact with the vibrating portion 30 and a second state in which the locking member 53 is detached from the vibrating portion 30. In the second state, the vibrating portion 30 moves toward the braking portion 40 and comes into contact with the braking portion 40.

[0028] In one embodiment, the fixture 11 is substantially in the shape of a plate body, the guide structure 13 is provided on one side of the fixture 11 and fixedly connected to the fixture 11. The vibrating portion 30 may be a linear resonator. The vibrating portion 30 is movably fitted and connected to the guide structure 13, and the braking portion 40 is fixed to the surface of the fixture 11 facing the vibrating portion 30. Of course, the guide structure 13 may be provided to surround the braking portion 40 or may be provided on one side of the guide portion, and is not limited here. Optionally, the guide structure 13 may be one or more guide bars 131 connected to the fixture 11. The vibrating portion 30 is fitted in the guide bar 131, and a rail groove may be provided in the guide structure 13, and the vibrating portion 30 is slidably provided in the rail groove. A vibrator 33 that vibrates along a certain direction is provided in the vibrating portion 30. As can be understood, the vibrator 33 has a certain mass so as to have sufficient energy during vibration.

[0029] In this embodiment, the locking portion 50 is provided on one side of the vibrating portion 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 member 53 to translate or rotate relative to the vibrating portion 30 so as to approach or separate from it.

[0030] Referring to FIGS. 6 to 10 in combination, in one embodiment, in order for the driving exciter 100 to generate one complete anisotropic vibration, the following steps are required: Energy storage stage: Referring to FIG. 6, an electric drive signal is input to the vibrating portion 30, and an excitation magnetic field is generated in the vibration cavity to drive the vibrator 33 to continuously vibrate and store energy. At this time, the driving exciter 100 is in the first state, and the locking member 53 is abutted against the side surface of the vibrating portion 30 to relatively fix the vibrating portion 30 in the vibration direction of the vibrator 33. Release stage: Referring to FIG. 7, the driver 51 drives the locking member 53 to translate or rotate until the locking member 53 disengages from the vibrating portion 30, and the driving exciter 100 is transitioned to the second state. Moving stage: Referring to FIG. 8, at this time, the driving exciter 100 is in the second state, the vibrating portion 30 is disengaged from the restraint of the locking member 53, and driven by the internal vibrator 33, the fixture 11 moves to the braking portion 40 provided. Braking stage: Referring to FIG. 9, the braking portion 30 abuts against the braking portion 40. The braking portion 30 receives the energy due to the vibration of the vibrator 33 to generate anisotropic vibration and generate a tensile feeling or a force feeling in the normal direction of the contact surface between the two. Return stage: Referring to FIG. 10, after one anisotropic vibration occurs, the vibrating portion 30 leaves the braking portion 40, the driving exciter 100 is restored to the first state, waits for the next trigger, and the anisotropic vibration stops.

[0031] As can be understood, in the above embodiment, the generation of anisotropic vibration is not due to the vibration of the vibrating portion 30 itself, but is caused by the fitting between the braking portion 40 and the vibrating portion 30. That is, the braking portion 40 brakes the vibrating portion 30 to generate anisotropic vibration, the vibrating portion 30 leaves the braking portion 30, and the anisotropic vibration stops.

[0032] After going through the above several steps, the driving exciter 100 can generate one anisotropic vibration. By circulating the above process multiple times within a certain period, multiple anisotropic vibrations can be discretely generated. Furthermore, by controlling the moving frequency of the vibrating part 30, the frequency at which the anisotropic vibration occurs can be controlled, and by changing parameters such as the mass or the magnitude of the current of the vibrating part 30, the magnitude of the anisotropic vibration can be changed.

[0033] The technical solution of the present application is to switch the driving exciter 100 between a first state 100 and a second state by a lock material 53 provided movably. In the first state, the vibrating part 30 is relatively fixed. In the second state, the vibrating part 30 is brought into contact with the braking part 40, and the braking part 40 brakes the vibrating part 30 to generate an anisotropic vibration. Since the generation of this anisotropic vibration requires the fitting of the braking part 40 and the vibrating part 30, the frequency at which the vibration occurs depends on the frequency at which the vibrating part 30 moves and comes into contact with the braking part 40. Therefore, when the lock material 53 continuously moves and continuously switches between the first state and the second state, the vibrating part 30 is intermittently brought into contact with the braking part 40, so that the anisotropic vibration can be discretely generated.

[0034] The technical solution of the present application can greatly expand the asymmetry of the anisotropic vibration and discretely present the asymmetric vibration in a short time. By generating a vibration close to the actually occurring asymmetric vibration force, a clear sense of force in a certain direction can be discretely presented in a short time. Since the direction of this sense of force depends on the contact direction between the braking part 40 and the vibrator 30, it is not limited to the gripping method.

[0035] Referring to FIGS. 6 to 10, in one embodiment of the present invention, the locking part 50 includes two lock materials 53 located on both sides of the vibrating part 30 to form a position regulation space. The driver 51 is connected to at least one lock material 53. Here, in the first state, the vibrating part 30 is position-regulated within the position regulation space.

[0036] In this embodiment, the locking member 53 may be a block-shaped main body or a rod-shaped main body. The vibration direction of the vibrating member 33 is the left-right direction. Optionally, the braking portion 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, thereby switching the drive exciter 100 between the first state and the second state.

[0037] 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 to form 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 move the other side of the locking member 53 closer to or 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.

[0038] In an embodiment of another aspect of the present invention, the driver 51 drives the locking member 53 to perform a linear movement, and the movement direction of the locking member 53 is provided to form an angle with the vibration direction of the vibrator 33. 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, and the locking member 53 is connected to the mover. Preferably, the straight line in which the movement 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 to form 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.

[0039] 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.

[0040] 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 actuator 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 facing 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 actuator 51 enters the position regulating groove 55a, and one end of the locking member 53 away from the actuator 51 protrudes from the notch 55b. The locking member 53 rotates between two opposing side walls of the notch 55b.

[0041] 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 actuator 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.

[0042] In this embodiment, referring to FIG. 2, the stopper 55 has a structure like a cap with an unrestricted shape. The opening of the position regulating groove 55a faces the locking member 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 member 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 member 53 into the space between the two side walls of the notch 55b. When the locking member 53 abuts against one of its side walls, the locking member 53 also just abuts against the vibrating part 30. When the locking member 53 abuts against the other side wall, the locking member 53 disengages from the vibrating part 30. Adding the stopper 55 to limit the movement range of the locking member 53 is advantageous for offsetting the inertia of the locking member 53 to a certain extent, and improving the operating efficiency and stability of the locking member 53.

[0043] 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.

[0044] 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 elastic members 37 provided on both sides along the vibration direction of the vibrator 33 to connect the housing 31 and the ends of the vibrator 33.

[0045] In this embodiment, the housing 31 includes two end caps provided opposite to each other and a connecting plate provided between the two end caps for connecting the two end caps. Two mounting ears are respectively provided on both sides of each end cap. A retraction hole through which the guide bar 131 penetrates is provided in the mounting ear. The mounting ears between the two end caps are provided opposite to each other and are connected by the sleeve 311.

[0046] The vibrator 33 vibrates along a direction within the vibration space. The vibrator 33 drives and vibrates the elastic member 37 simultaneously with the vibration, stores the generated energy in the elastic member 37, and when the housing 31 comes into contact with the braking part 40, the stored energy is released to the braking part 40 to generate a vibration wave. Since the vibrating part 30 comes into contact with the braking part 40 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.

[0047] 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 which are provided oppositely and fixedly connected to the housing 31. One end of the elastic member 37 is connected to the first link plate 34 or the second link plate 35, and the other end is a spring piece connected to the end of the vibrator 33. Optionally, the cross-section of the vibrator 33 in this embodiment is a substantially parallelogram, and its vibration direction is 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. By arranging it in this way, the elasticity of the spring piece can be better utilized, and the amplitudes of the vibrator 33 and the spring piece can be increased equally.

[0048] In one embodiment of the present invention, in order to protect the hardware and achieve a good vibration effect, a buffer 39 towards the braking part 40 is provided at the end of the housing 31 along the vibration direction of the vibrator 33. The buffer 39 is a spring, or the buffer 39 is rubber, or the buffer 39 is foam, or the buffer 39 is composed of at least two of spring, rubber and foam provided in series or in parallel.

[0049] Referring to FIG. 1, in one embodiment of the present invention, the drive exciter 100 further includes a reset member 60 which is a spring whose both ends are 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.

[0050] Of course, the reset member 60 is not limited to a spring, and may be other structures capable of resetting the vibrating part 30.

[0051] In one embodiment of the present invention, the braking part 40 is a spring, or the braking part 40 is rubber, or the braking part 40 is foam, or at least two of the spring, rubber and foam are provided in series or in parallel, that is, two or three of the spring, rubber and foam are sequentially connected end to end so as to obtain a good braking effect, or are provided in parallel so as to brake the vibrating part 30 and ensure the structural stability.

[0052] Two platens to which a spring, rubber and foam are connected in parallel or in series may be separately provided for the braking part 40. One platen is connected to the fixture 11, and the other platen is used to abut against the vibrating part 30. In this way, the structure of the brake part 40 is made more stable and reliable.

[0053] 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, and 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.

[0054] In this embodiment, at least one second connection frame 17 is provided between the two fixtures 11, and both ends of the second connection frame are respectively connected to the fixtures 11 to ensure the structural stability. The two locking members 53 may be provided on the same side or on different sides, and the two locking members 53 are movable. However, in the second state, only one of the locking members 53 moves and detaches from the vibrating part 30. For example, when the right locking member 53 moves, the left locking member 53 is fixed, the vibrating part 30 moves in the right direction, and when the left locking member 53 moves, the right locking member 53 is fixed, and the vibrating part 30 moves in the left direction. That is, in the second state, the vibrating part 30 can only approach 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.

[0055] Optionally, the guide structure 13 is a guide bar 131. A plurality of guide bars 131 may be provided, and a plurality of locking parts 50 may also be provided. The guide bar 131 and the locking part 50 intersect in the circumferential direction of the vibrating part 30 and are provided at intervals, and the number of locking members 53 provided on both sides of the vibrating direction of the vibrating part 30 is the same and the positions are symmetric, ensuring that the force is uniform and the structure is stable.

[0056] 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. The 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 braking part 40 is fixedly connected to the cover plate 113 through the through hole 111a. The cover plate 113 is bolted to the mounting body 111, and the braking part 40 is adhesively or bolted to the cover plate 113. Due to the interaction between the vibrating part 30 and the braking part 40, hardware loss cannot be avoided. In this embodiment, by removing the cover plate 113, the replacement of the braking part 40 or the maintenance of the equipment can be easily and quickly realized.

[0057] The present invention further relates to an electronic device including the drive exciter 100 of any one of the above embodiments. For the specific structure of the drive exciter 100, refer to the above embodiments. Since this electronic device adopts all the technical solution means of all the above embodiments, it has at least all the beneficial effects brought about by the technical solution means of the above embodiments, so it will not be described further here.

[0058] Here, in some applications of the drive exciter 100, the electronic device may be a tactile device such as a handle or a VR all-in-one.

[0059] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention.
