Description

Technical Field

[0001] The present invention relates to a tactile device and a tactile module, and more particularly to a tactile device and a tactile module that can realize various tactile modes with less energy by combining a vibration part including a magnetorheological elastomer and an elastic support part having elastic properties. Background Art

[0002] Generally, the actuators used in tactile technology include magnetorheological elastomer (MRE) actuators, inertial actuators, piezoelectric actuators, electroactive polymer (EAP) actuators, electrostatic actuators, etc. Magnetorheological elastomer actuators are composed of magnetic particles, base materials and magnetic field generating parts, and provide various tactile elements based on the strength, direction and frequency of the magnetic field. Inertial actuators include eccentric motors that vibrate using the centrifugal force generated when the motor rotates, and linear resonant actuators (LRA) that maximize the vibration intensity using the resonant frequency. Piezoelectric actuators have a beam or disk form and are driven by piezoelectric elements whose size or shape changes instantaneously due to the electric field. Electroactive polymer actuators attach a mass body to an electroactive polymer film and generate vibrations through the repeated movement of the mass body. Electrostatic actuators are driven by the attractive force generated between two glass surfaces charged with different charges, and the repulsive force generated when the same charges are applied. Furthermore, devices that utilize shape memory alloys, macro-composite fibers, electrotactile sensing, electrostatic friction, ultrasound, and sound radiation pressure are being developed.

[0003] Figure 1 This is a schematic diagram of a linear resonant actuator. A typical linear resonant motor consists of magnets, coils, suspension, and other components.

[0004] In addition, in the magnetorheological elastomer actuator, the polarity of the magnetic field generated in the solenoid coil, i.e., the north pole and the south pole, alternates according to the frequency of the voltage or current applied in the coil, and at the same time, the morphology of the magnetorheological elastomer changes based on the attraction or repulsion force, thereby achieving a tactile effect.

Similar figure numbers in the drawings refer to the same or similar functions in various aspects. For convenience, length, area, thickness, etc. and their forms may also be exaggerated.

[0052] In order to enable those skilled in the art to easily implement the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0053] Figure 2 is a structural diagram of a haptic device 10 according to an embodiment of the present invention. Figure 3 1 is a schematic top view of the elastic support portion 2 according to multiple embodiments of the present invention. Figure 4 1 and 2 are schematic side cross-sectional views and schematic top views of the magnetic field generating unit 3 according to various embodiments of the present invention.

[0054] The haptic device 10 (or magnetorheological elastomer haptic device 10 ) of the present invention achieves tactile sensation by utilizing the spring tension of the vibrating portion 1 and the elastic support portion 2 . The magnetic poles and the magnetic field generated by the magnetic field generating portion 3 generate attractive and repulsive forces, thereby driving the vibrating portion 1 up and down.

[0055] Reference Figure 2 (a), the elastic supporting part 2 may be connected to the vibration part 1.

[0056] The vibrating portion 1 (or magnetorheological elastomer vibrating portion 1) may include a magnetorheological elastomer, which is an elastic material with magnetic particles dispersed in a matrix. The vibrating portion 1 itself may also be composed of a magnetorheological elastomer. To achieve a thin structure for the haptic device 10, the vibrating portion 1 is preferably thin and flat. However, to diversify the tactile patterns, the vibrating portion 1 may be deformed.

[0057] The elastic support portion 2 may include an edge portion 2a, a connecting portion 2b, and a driving portion 2c. The edge portion 2a, the connecting portion 2b, and the driving portion 2c may be integrated or connected to each other as independent elements.

[0058] The edge portion 2 a constitutes an outer edge frame of the elastic support portion 2 and can be supported or inserted into the side wall of the housing 4 .

[0059] The connecting portion 2b can connect the edge portion 2a and the driving portion 2c. Figure 2 Although only four connecting portions 2b are shown in FIG. 1 (a), the number of connecting portions 2b may be one or more as long as the edge portion 2a and the driving portion 2c can be connected.

[0060] The connecting portion 2b is supported on the edge portion 2a and provides spring resilience, enabling the vertical movement of the driving portion 2c. To this end, the length of the connecting portion 2b is preferably greater than the linear distance from the edge portion 2a to the driving portion 2c. If the length were equal to the linear distance from the edge portion 2a to the driving portion 2c, the driving portion 2c would have difficulty in vertical movement. The connecting portion 2b is preferably curved or has multiple curvatures.

[0061] Reference Figure 3 In (a), the four connecting portions 2b extend in a curved shape from the center of each side of the edge portion 2a and are connected to the circular driving portion 2c.

[0062] Reference Figure 3 In the embodiment (b), the two connecting portions 2b extend linearly from the center of each side of the edge portion 2a and connect to the drive portion 2c. However, in this embodiment, the connecting portions 2b can be formed of a stretchable material, thereby making the length of the connecting portions 2b greater than the linear distance from the edge portion 2a to the drive portion 2c.

[0063] Reference Figure 3 (c) The four connecting portions 2b extend from the four corners of the edge portion 2a in a shape having multiple curvatures and are respectively connected to the four corners of the quadrangular driving portion 2c.

[0064] The driver 2c is connected to the vibrating unit 1 and can be driven vertically. When the vibrating unit 1 is driven vertically by the magnetic field applied by the magnetic field generating unit 3, the driver 2c connected to the vibrating unit 1 can also be driven vertically. The area of ​​the driver 2c is preferably larger than that of the vibrating unit 1.

[0065] In addition, if the elastic support part 2 is a structure that uses its spring tension to drive the vibration part 1 up and down, the shape and material are not affected. Figure 2 、 Figure 3 restrictions.

[0066] Reference Figure 2(b) A magnetic field generating unit 3 may be disposed within the housing 4. The magnetic field generating unit 3 may employ means for controlling the direction of the magnetic field. Preferably, the magnetic field generating unit 3 includes a solenoid coil, and the direction of the magnetic field can be changed by controlling the direction of the current flowing therein. The magnetic field generating unit 3 may be disposed horizontally within the housing 4 and configured to apply a magnetic field from the lower portion to the upper portion of the vibrating unit 1 disposed in the center portion. For this reason, the vibrating unit 1 is preferably disposed at intervals at the ends of the solenoid coil.

[0067] Reference Figure 4 (a) shows coil 3a wound around post 3b. A magnetic field is applied to vibrating section 1, causing it to move up and down. Vibrating section 1 is positioned above and spaced from the ends of each coil. Furthermore, since vibrating section 1 is connected to elastic support section 2, even with less energy applied than would normally be required to drive vibrating section 1 up and down, the spring properties of elastic support section 2 can further increase the amount of movement.

[0068] Reference Figure 4 (b) and (c), the applied form of the magnetic field can be changed according to the shape of the pillar 3b. Figure 4 (d) and (e), the magnetic field generating parts 3 can be arranged in parallel or in the direction of the linear angle. As long as the resultant magnetic field force of each magnetic field generating part 3 can be transmitted to the vibrating part 1 in the upper center and driven up and down, the configuration form and number of the magnetic field generating parts 3 can be changed without restriction.

[0069] Alternatively, the magnetic field generating unit 3 may include no pillars 3b and may be composed only of the coils 3a. The number of coils 3a may be singular or plural, and the coils 3a may be arranged vertically or horizontally.

[0070] The housing 4 may be open on at least one side (e.g., the top). The housing 4 may include a sidewall 4a and a groove 4b extending horizontally from the sidewall 4a. The interior of the housing 4 surrounding the sidewall 4a provides space for the vibrating unit 1 to move up and down, and also provides space for arranging the magnetic field generating unit 3.

[0071] The edge portion 2a of the elastic support portion 2 can be disposed on the open side of the housing 4, i.e., the upper portion of the side wall 4a. The lower portion of the side wall 4a of the housing 4 can be open or have a lower surface integral with the side wall 4a. When the lower portion of the side wall 4a is open, the control unit body 5a can be disposed therein.

[0072] The control unit 5 may include a control unit body 5a and a terminal portion 5b. The control unit body 5a may constitute the lower surface of the housing 4, and the portion extending from the control unit body 5a to the outside of the housing 4 constitutes the terminal portion 5b.

[0073] The control unit 5 is formed with a circuit 6, which allows electrical / magnetic energy signals to be transmitted from an external signal input terminal (not shown) to the magnetic field generating unit 3. The circuit 6 can be formed from the terminal portion 5b to the magnetic field generating unit 3 on the control unit body 5a. To achieve a relatively thin control unit 5, the circuit 6 is preferably a flexible printed circuit board.

[0074] Reference Figure 2 (c) , the haptic device 10 shown in the figure is made by connecting a combination of the vibration part 1 and the elastic support part 2 in a state where the control part 5 is connected to the lower surface of the housing 4 and the magnetic field generating part 3 is arranged inside the housing 4 .

[0075] The tactile device 10 of the present invention can be driven by the spring tension of the elastic support part 2 and the attractive and repulsive forces of the magnetorheological elastomer magnetic poles of the vibration part 1, so that it can be driven even if a relatively small magnetic field is applied. Therefore, it can solve the problem that the existing magnetorheological elastomer actuator requires a large amount of magnetic field and generates serious heat in order to achieve the required force. In addition, the magnetorheological elastomer of the vibration part 1 is also driven while undergoing minute deformation based on the magnetic field, thereby achieving vibration through the sum of the elastic movement of the elastic support part 2 and the deformation movement based on the magnetic field applied by the magnetorheological elastomer, thereby overcoming simple vibration and achieving vibration with a tactile mode. In addition, compared with Figure 1 Compared with existing LRAs, the use of magnetorheological elastomers can achieve an ultra-thin tactile module, which has the advantage of being able to be driven with less energy.

[0076] Figure 5 FIG. 1 is a schematic front view of a haptic module 100 according to an embodiment of the present invention. Figure 6 1 is a schematic perspective view and a schematic side cross-sectional view of a haptic module 100 according to an embodiment of the present invention.

[0077] Reference Figure 5 and Figure 6 The haptic module 100 (or the magnetorheological elastomer haptic module 100 ) includes a haptic device 10 , a fixing portion 21 , a tactile transmission portion 24 , and may further include a cover portion 25 .

[0078] The fixing portion 21 may be formed with an insertion hole 23 for inserting the haptic device 10. The insertion hole 23 preferably has a shape corresponding to the haptic device 10, but any specific shape is not limited as long as it allows the haptic device 10 to be inserted. After the haptic device 10 is inserted into the insertion hole 23, the groove 4b of the housing 4 of the haptic device 10 and the groove 22 of the fixing portion 21 can be connected and fixed using screws or the like. The upper surface of the haptic device 10 can pass through the insertion hole 23 and be located at a height corresponding to the upper portion of the fixing portion 21.

[0079] The fixing portion 21 may be connected to a tactile transmission portion 24. The tactile transmission portion 24 has no holes and can cover the entire upper surface of the fixing portion 21. The upper surface of the haptic device 10 contacts the lower surface of the tactile transmission portion 24 via the through-hole 23. Figure 5 The figure shows an example in which a single insertion hole 23 is formed in the fixing portion 21. However, a plurality of insertion holes 23 may be formed to accommodate insertion of a plurality of haptic devices 10. Furthermore, a plurality of insertion holes 23 of varying sizes and shapes may be formed, and haptic devices 10 corresponding to the shapes of the insertion holes 23 may be inserted therein, thereby providing various tactile sensations according to different regions of the tactile sensation transmitting portion 24.

[0080] The fixing portion 21 can be made of a hard material, and the touch transmission portion 24 can be made of a soft material. Thus, the tactile device 10 can be firmly fixed in the fixing portion 21 made of the hard material, and the center C of the touch transmission portion 24 made of the soft material [refer to Figure 6 The haptic device 10 provides a tactile sensation through the vertical movement of the vibrating portion 1 and the elastic supporting portion 2. For example, a dual injection molding structure can be used, where the fixing portion 21 is made of a hard material such as polycarbonate (PC), and the tactile sensation transmitting portion 24 is made of a soft material such as thermoplastic polyurethane (TPU) or thermoplastic elastomer (TPE).

[0081] The fixing portion 21 is hollow in the center due to being inserted into the hole 23. Therefore, the vibration force in the area surrounded by the fixing portion is weak, while the central portion generates a localized vibration force due to the haptic device 10 inserted into the hole 23. The localized vibration force can be transmitted to the upper portion through the tactile transmission portion 24 made of soft material.

[0082] A cover 25 may be further formed on the tactile transmission portion 24. The cover 25 is made of a material such as glass and receives the tactile sensation transmitted from the tactile transmission portion 24. However, the cover 25 may not be included. The target object (for example, glass, a display, etc.) to which the tactile module 100 is to be applied can serve as the cover 25. By attaching the tactile module 100 to the target object, tactile sensation can be transmitted, thereby enabling application in various situations requiring localized tactile sensation.

[0083] Existing haptic motors consist of permanent magnets, coils, and components for attaching them. This limits their height and hinders their application in products that require only localized vibration, transmitting vibration force to the entire structure surrounding the motor or surrounding it. In contrast, the present invention utilizes a magnetorheological elastomer. This material's deformation allows it to be applied to the surfaces of various devices, providing a localized tactile sensation.

[0084] Figure 7 1 is a schematic top view and a schematic side cross-sectional view of a haptic module implementing a local haptic sense according to an embodiment of the present invention.

[0085] The vibration part 1 of the present invention can have various deformations, and the magnetic field polarity of the magnetic field generating part 3 can be changed into various forms, so that it can not only make simple up and down linear motion, but also change to zigzag up and down motion, etc., so the present invention can provide various tactile sensations.

[0086] As an example, refer to Figure 7 (a) and (b) , the surface polarity of the vibration part 1 is divided into various forms so as to match the magnetic field polarity of the magnetic field generating part 3 . Figure 7 (a) shows a configuration in which the vibration portion 1 has one polarity and can move up and down based on application of a magnetic field. Figure 7 In (b), the vibrating portion 1 is divided into multiple regions 1a and 1b with different polarities. Even when the same magnetic field is applied, region 1a moves upward, while region 1b moves downward, causing the vibrating portion 1 to twist or move up and down in a zigzag pattern. This can provide various tactile sensations to the center portion C of the tactile sensation transmitting portion 24. This makes it possible to provide various drive sources and ensure a variety of drive modes.

[0087] Figure 8 FIG. 1 illustrates the intensity of local tactile sensation of a tactile module according to an experimental example of the present invention.

[0088] like Figure 5 and Figure 6 As described above, the structures of the fixing portion 21 and the tactile transmission portion 24 are formed by dual injection molding [for example, the fixing portion 21 is made of polycarbonate and the tactile transmission portion 24 is made of thermoplastic elastomer]. Therefore, when the tactile device 10 is in close contact with the soft material of the tactile transmission portion 24 made of thermoplastic elastomer, the tactile sensation can be maximized.

[0089] Reference Figure 8 As can be seen from the upper graph of FIG, the central portion C of the tactile sensation transmitting portion 24 directly receives vibration from the magnetorheological elastic body of the tactile device 10, so the tactile intensity is strong. Figure 8 As can be seen from the lower graph, the edge E of the tactile sensation transmitting portion 242, which is directly connected to the fixing portion 21, has a relatively low tactile intensity due to the hard polycarbonate material of the fixing portion 21. Therefore, various tactile sensations of various shapes and intensities can be achieved depending on the shape of the insertion hole 23 of the fixing portion 21.

[0090] Figure 9 1 and 2 are schematic diagrams of devices 200 and 300 to which the haptic module of the present invention is applied.

[0091] Reference Figure 9 By applying the haptic module 100 to the surface of devices such as game controllers, joysticks, mice, keyboards, tablet computers, and smartphones, haptic sensations corresponding to various operating conditions can be provided. The haptic module can be applied to the surface of any device or structure that can come into contact with the user.

[0092] Multiple haptic modules 100 can be respectively applied to the three-dimensional surface of the device 200. The multiple haptic modules 100 can not only provide haptic sensations in multiple areas of the same horizontal plane, but also provide haptic sensations in different directions on the three-dimensional surface.

[0093] Figure 9 (a) shows an example of applying the haptic module 100: 100a to 100d in the game controller 200. The haptic module 100 is disposed on the handle portions 100a and 100b or the peripheries of the buttons 100c and 100d that are touched by the user, thereby providing a haptic sense.

[0094] Figure 9 (b) shows an example of applying the haptic module 100: 100e to 100i in the tablet computer 300. The haptic module 100 is arranged at the gripping parts 100e, 100f, 100g, and 100h of the tablet computer 300 or at the wide surface 100i of the tablet computer 300, thereby providing a tactile sense.

[0095] Each tactile module 100: 100a-100i has a different configuration direction, and can provide tactile sensations in different directions, so that the user can experience a variety of tactile sensations according to different usage situations, and can experience a more three-dimensional and realistic tactile sensation.

[0096] As described above, the present invention has been illustrated and described with reference to preferred embodiments. However, the present invention is not limited to the above embodiments. Various modifications and variations can be made by those skilled in the art without departing from the spirit of the present invention. Such modifications and variations are intended to fall within the scope of the present invention and the appended claims.
