Description

Technical Field

[0001] This invention relates to a vibration presentation device. Background Technology

[0002] Currently, touch panels with vibration feedback function are known to vibrate the control panel based on the detection results of the load applied to the control panel.

[0003] For example, Patent Document 1 discloses a touch panel that includes electrodes, a sensor elastomer portion opposite to the electrodes, a detection unit for detecting loads applied to the operation panel, and a vibration elastomer portion for transmitting vibrations generated by the operation of an actuator to the operation panel. The sensor elastomer portion is configured such that the vibration elastomer is pressed away from the electrodes due to the load applied to the operation panel. The detection unit detects the change in electrostatic capacitance between the electrodes and the sensor elastomer portion as the sensor elastomer portion moves away from the electrodes, and detects the magnitude of the load applied to the operation panel based on the magnitude of the change in electrostatic capacitance.

[0004] Furthermore, as a method for detecting the magnitude of the load applied to a component, a load detection method is disclosed, for example, comprising a component made of a strongly magnetic material, an excitation coil that generates leakage flux in the component, and a detection coil that detects the generated leakage flux, and the magnitude of the load is detected based on the detected leakage flux (see, for example, Patent Document 2).

[0008] Patent Document 2: Japanese Patent Application Publication No. 02-145934 Summary of the Invention

[0009] The problem that the invention aims to solve

[0010] However, in the touch panel of Patent Document 1, the load applied to the operation panel is detected as a change in capacitance. This change in capacitance depends on the distance between the vibrating elastomer on the movable side and the electrode on the fixed side. Therefore, due to the high degree of assemblability and post-installation calibration, it is difficult to reduce costs.

[0011] Furthermore, even when using the load detection method of Patent Document 2 to detect the change in leakage flux as the load applied to the operation panel, the change in leakage flux depends on the distance between the excitation coil and the detection coil. Therefore, similar to the touch panel of Patent Document 1, the high degree of assemblability and post-installation calibration makes it difficult to reduce costs.

[0012] The purpose of this invention is to provide a vibration presentation device that can reduce the costs associated with assembly, post-installation calibration, and other related expenses.

[0013] Solution for solving the problem

[0014] The vibration presentation device of the present invention includes:

[0015] Support section;

[0016] The supported part is equipped with a vibration actuator;

[0017] Positioning plate, which is equipped with strain gauges; and

[0018] The connecting component has a leaf spring portion.

[0019] The supported part is supported by the supporting part via the positioning plate and the connecting component.

[0020] The effects of the invention are as follows.

[0021] According to the present invention, the costs associated with assembly, post-installation calibration, etc., can be reduced. Attached Figure Description

[0044] <Overall Structure of the Vibration Presentation Device>

[0045] The vibration presentation device 1A according to embodiments of the present invention can be used, for example, as a central control console located in the interior of a vehicle, or as a remote control for an operator to operate various devices. Furthermore, the application of the vibration presentation device 1A according to embodiments of the present invention is not limited to the aforementioned device and can be applied to various objects. Figures 1 to 6 The vibration presentation device 1A shown has an operation panel 101 and a vibration actuator 1, and has a vibration feedback function that causes the operation panel 101 to vibrate in the left-right direction (X direction) when the operation panel 101 is pressed from the front side (+Z direction) to the back side (-Z direction).

[0046] The vibration presentation device 1A includes a support part 1B, a supported part 1C, a vibration damper 270, a positioning plate 310, and a connecting part 350. The support part 1B includes a fixing clamp 210, a fixing plate 230, and a protective cover 250. The supported part 1C includes the aforementioned operation panel 101, panel base 104, and the aforementioned vibration actuator 1.

[0047] (Operation Panel 101)

[0048] The operation panel 101 is formed of polycarbonate material or the like, and has a rectangular shape with the left-right direction (X direction) as the length direction and the up-down direction (Y direction) as the width direction. It has a front side 102 facing the front side (+Z direction) and a back side 103 facing the back side (-Z direction).

[0049] The front panel 102 is the operating surface for the user to perform the pressing operation. On the back panel 103, a circuit board (not shown) is disposed parallel to the operation panel 101. The circuit board includes display control circuitry for displaying images on the operation panel 101. Furthermore, a panel base 104 is disposed on the back panel 103.

[0050] (Panel base 104)

[0051] The panel base 104 supports the operation panel 101 on the back side 103. The panel base 104 is a flat plate-shaped component formed from polycarbonate, aluminum, resin, or other materials and having a predetermined thickness. It has a rectangular shape corresponding to the shape of the operation panel 101, and has a surface 105 facing the front side (+Z direction) and a back side 106 facing the back side (-Z direction). Furthermore, the position of the panel base 104 as linearly symmetrical about the center line in the left-right direction (X direction) is sometimes referred to as "left-right symmetry".

[0052] The panel base 104 has holes 107, 108, and 109. Holes 107 are for supporting the operation panel 101 and are respectively disposed at the four corners of the rectangular shape of the panel base 104. Holes 108 are for fixing the vibration actuator 1 and are arranged symmetrically on both sides and top and bottom in the rectangular shape of the panel base 104. Holes 109 are for fixing the panel base 104 to the positioning plate 310 and are arranged symmetrically on both sides in the rectangular shape of the panel base 104.

[0053] The panel base 104 and the operation panel 101 together constitute the supported portion 1C, and therefore can be used as a component to adjust the weight of the supported portion 1C. Furthermore, since the panel base 104 supports the operation panel 101 on the back surface 103, the rigidity of the operation panel can be improved. And, as... Figure 7 As shown, the panel base 104 serves as a fixing part for fixing the vibration actuator 1 to its back side 106 via the bracket 2. Furthermore, the panel base 104 also serves as a fixing part for fixing the positioning plate 310.

[0054] (Vibration actuator 1)

[0055] Figure 7 This is a perspective view showing a vibration actuator or the like disposed inside between the support and the supported part in an embodiment of the present invention. Figure 8 yes Figure 2 The figure is a sectional view along line AA. Figure 9 This is an exploded perspective view of a vibration actuator in an embodiment of the present invention, showing the state after disassembling the outer casing and the internal drive unit. Figure 10This is a longitudinal sectional view of the vibration actuator according to an embodiment of the present invention. Figure 11 This is a perspective view of a coil assembly in an embodiment of the present invention, showing the state in which the coil has been removed from the coil holding part. Figure 12 This is an exploded perspective view of the movable body with the elastic support portion installed in an embodiment of the present invention.

[0056] The vibration actuator 1 vibrates by being driven, giving the user a sense of operation when pressing the operation panel 101. Figure 9 The vibration direction of the vibration actuator 1 is shown in the vertical direction. Additionally, sometimes... Figure 9 The vertical direction shown is called the "axial direction". Vibration actuator 1 makes the axial direction... Figure 2 The device is mounted on the back 106 of the panel base 104 in the left-right direction (X direction) as shown. The bracket 2 and hole 108 (see reference) are used in the mounting of the vibration actuator 1. Figure 1 ).

[0057] like Figure 9 As shown, the vibration actuator 1 has a drive unit 15. The drive unit 15 has a movable body 20 (see reference). Figure 12 ), fixed body 40 and elastic support parts 81 and 82.

[0058] <20 movable bodies>

[0059] The movable body 20 is disposed circumferentially spaced inside the cylindrical coil holding portion of the fixed body. The movable body 20 is cylindrical and supported to reciprocate axially along the inner circumferential surface of the coil holding portion 42. The movable body 20 is connected to the inner circumferential portion of the elastic support portion at its two ends (upper and lower ends) separated along the axial direction (vibration direction). The movable body 20 has a magnet 21, a pair of magnetic yokes 23 and 25, a pair of counterweights 27 and 29, and a pair of connecting portions 31 and 33. The magnet 21 is disposed at the center of the movable body 20 (the central portion in the vibration direction). The pair of magnetic yokes 23 and 25, the pair of counterweights 27 and 29, and the pair of connecting portions 31 and 33 are symmetrically arranged with respect to the magnet 21.

[0060] Magnet 21 is a solid cylindrical component magnetized in the vibration direction. The polarities of the separate surface and back side of magnet 21 in the vibration direction are different. Magnet 21 is arranged inside coils 61 and 62 with its two magnetized surfaces facing the extension direction of the axis of coils 61 and 62, respectively.

[0061] A pair of magnetic yokes 23 and 25 are magnetic bodies. Magnetic yoke 23 is fixed to the surface of magnet 21. Magnetic yoke 25 is fixed to the back of magnet 21.

[0062] The counterweights 27 and 29 are made of non-magnetic materials. The counterweight 27 is stacked on the magnetic yoke 23. The counterweight 29 is stacked on the magnetic yoke 25.

[0063] like Figure 10 and Figure 12 As shown, connecting part 31 connects the magnetic yoke 23, the counterweight 27, and the elastic support part 81. Connecting part 33 connects the magnetic yoke 25, the counterweight 29, and the elastic support part 82. Furthermore, a vibration damper (not shown) is installed on the elastic support part 81 as a damping mechanism to attenuate vibrations generated in the elastic support part 81. And a vibration damper (not shown) is installed on the elastic support part 82 as a damping mechanism to attenuate vibrations generated in the elastic support part 82.

[0064] <Fixed Body 40>

[0065] The fixed body 40 is supported by elastic supports 81 and 82 that move freely along the axial direction of the movable body 20 (which is both the vibration direction and the coil axis). The fixed body 40 has a housing 10, a coil holding part 42, a pair of coils 61 and 62, and an outer magnetic yoke 50.

[0066] The outer shell 10 is a hollow cylinder comprising a bottom cylindrical body 11 and a cover 12.

[0067] like Figure 11 As shown, the coil holding part 42 has a cylindrical body part 422 and flange parts 426, 427, and 428. The cylindrical body part 422 is formed in a cylindrical shape using a raw material containing phenolic resin such as bakelite. The flange parts 426, 427, and 428 protrude radially from the outer peripheral surface of the cylindrical body part 422. The flange parts 426, 427, and 428 are arranged to be axially separated from each other. The flange part 426 is located at the axial center of the cylindrical body part 422, the flange part 427 is located at one axial end of the cylindrical body part 422, and the flange part 428 is located at the other axial end of the cylindrical body part 422.

[0068] Coil 61 is wound between flanges 426 and 427. Coil 62 is wound between flanges 426 and 428. Coils 61 and 62 are connected to external devices (e.g., power supply units) in a manner that allows power to be supplied to coils 61 and 62 from the external devices. In the vibration actuator 1, coils 61 and 62, with the axial direction (magnetization direction of magnet 21) as the vibration direction, together with magnet 21 and yokes 23 and 25, form a magnetic circuit for generating a drive source.

[0069] like Figure 10As shown, the outer magnetic yoke 50 is a cylindrical magnetic body that surrounds the outer peripheral surface of the coil holding part 42 and is positioned radially outward to cover the coils 61 and 62. The outer magnetic yoke 50 and the coils 61 and 62 together form the magnetic circuit on the fixed body side, and together with the magnetic circuit on the movable body side, namely the magnet 21, magnetic yokes 23 and 25, they form a magnetic circuit. The outer magnetic yoke 50 prevents leakage magnetic flux from the magnetic circuit to the outside of the vibration actuator 1.

[0070] The main structure of the vibration actuator 1 has been described above. Next, the resonance of the vibration caused by the vibration actuator 1 in the vibration display device 1A will be explained. The resonance in the vibration display device 1A varies depending on the constituent components of the vibration system comprising the vibration display device 1A, the elastic support portion that elastically supports the aforementioned constituent components, and the damping mechanism that attenuates the vibration. Here, the vibration system including the protective cover 250, the fixing plate 230, the fixing clamp 210, and the excitation object (operation panel 101, panel base 104, and the fixed body 40 of the vibration actuator 1) is referred to as the "first vibration system." Furthermore, the vibration system including the aforementioned excitation object and the movable body 20 of the vibration actuator 1 is referred to as the "second vibration system."

[0071] The resonant frequencies of the first and second vibration systems can be obtained through simulation and experimentation. Figure 13 This is a diagram illustrating an example of the relationship between the resonant frequencies of a first vibration system and a second vibration system, obtained through simulation. Figure 13 The horizontal axis represents frequency [Hz], and the vertical axis represents acceleration [G]. Furthermore, the direction of acceleration is left-right (X-direction), and G is approximately 9.8 m / s². 2 ]. Figure 13 The initial peak value shows the resonant frequency f2 and acceleration of the second vibration system at resonance. The next peak value shows the resonant frequency f1 and acceleration of the first vibration system at resonance. Figure 13 As shown, the resonant frequency f1 of the first vibration system is higher than the resonant frequency f2 of the second vibration system (f1 > f2). In other words, the resonant frequency f2 of the second vibration system is lower than the resonant frequency f1 of the first vibration system.

[0072] As described above, since the resonance in the vibration presentation device 1A varies depending on its constituent components, elastic support, and attenuation mechanism, the resonant frequencies f1 and f2 of the first vibration system each have a certain range. Specifically, the resonant frequency f1 of the first vibration system is set to be above 80 Hz and below 300 Hz. The reason for setting the resonant frequency f1 is that human sensory organs can relatively easily perceive vibrations in the frequency band from 80 Hz to 300 Hz.

[0073] Furthermore, the resonant frequency f2 of the second vibration system is set to be above 50 Hz and below 80 Hz. The reason for setting it to above 50 Hz is to prevent the vibration presentation device 1A mounted on the vehicle from being affected by road noise (below 50 Hz) during vehicle operation. The reason for setting it to below 80 Hz is that, based on the simulation results described above, the resonant frequency f2 of the second vibration system needs to be set lower than the resonant frequency f1 of the first vibration system.

[0074] In this embodiment, the frequency characteristics of the vibration actuator 1 are configured to be changeable within a predetermined range. For example, an external device (e.g., a control unit not shown) sets the frequency characteristics of the vibration actuator 1 based on the resonant frequency f2 obtained from the simulation results described above.

[0075] <Elastic support parts 81, 82>

[0076] like Figure 10 and Figure 12 As shown, the elastic supports 81 and 82 support the movable body 20 so that it can move freely back and forth relative to the fixed body 40 along the vibration direction. The elastic supports 81 and 82 clamp the movable body 20 in the vibration direction and are mounted on both the movable body 20 and the fixed body 40 in a manner that intersects the vibration direction.

[0077] (Fixed clamp 210)

[0078] Next, refer to Figures 1 to 6 and Figure 8 The support part 1B will be described below. As described above, the support part 1B includes a fixing clamp 210, a fixing plate 230, and a protective cover 250. The fixing clamp 210 includes a platform 211 and an angle steel component 213. The platform 211 is a flat plate component with a predetermined plate thickness, and has a rectangular shape with the left-right direction (X direction) as the length direction and the depth direction (Z direction) as the width direction. It has an upper surface 215 facing upward (+Y direction) and a lower surface 217 facing downward (-Y direction).

[0079] Angle steel member 213 is symmetrically arranged on the upper surface 215. Angle steel member 213 has a predetermined plate thickness and an L-shape when viewed from the right. Angle steel member 213 has an upward extension 218 extending upward (+Y direction) from a central position in the depth direction (Z direction) of the upper surface 215, and a depth extension 219 extending in the depth direction (-Z direction) from a central position along the upper surface 215. The upward extension 218 has a support hole 218a for supporting the fixing plate 230. The depth extension 219 is fixed to the upper surface 215.

[0080] (Fixed plate 230)

[0081] The fixing plate 230 is a flat plate component with a predetermined plate thickness. It has a rectangular shape with the left-right direction (X direction) as the length direction and the up-down direction (Y direction) as the width direction. It has a front surface 231F facing the front side (+Z direction), a back surface 231B facing the back side (-Z direction), a right side surface 231R facing the right side (+X direction), a left side surface 231L facing the left side (-X direction), an upper surface 231A facing the upper side (+Y direction), and a lower surface 231U facing the lower side (-Y direction).

[0082] The fixing plate 230 has holes 232 and 233. Hole 232 is a through hole in the depth direction (Z direction) for supporting the fixing plate 230 on the angle steel member 213, and is positioned at the same location as hole 218a in the main view. Hole 233 is through which wires for transmitting power from external devices (e.g., batteries) to coils 61 and 62 respectively pass, and for power from strain gauge 330 (see reference). Figure 18 A through hole is provided on each side symmetrically, through which a signal line transmitting signals to an external device (such as a control unit not shown) passes.

[0083] The fixing plate 230 also has holes 234 and 235. Holes 234 are for fixing the connecting component 350, and two are arranged on the upper and lower sides of the right side 231R and the left side 231L respectively. Holes 235 are for mounting the protective cover 250, and three are arranged on the upper surface 231A and the lower surface 231U respectively, and one is arranged on the right side 231R and the left side 231L respectively.

[0084] (Protective cover 250)

[0085] like Figure 1 , Figure 7 and Figure 8As shown, the protective cover 250 has a first cover 251 and a second cover 252. The first cover 251 has an upper cover portion 253, a right cover portion 254, and a left cover portion 255. The upper cover portion 253 is a long strip-shaped plate with the X direction as its length direction and the Z direction as its width direction, configured to cover the gap in the depth direction (Z direction) between the support portion 1B (fixed plate 230) and the supported portion 1C (panel base 104) from the upper side (+Y direction). The right cover portion 254 is configured to extend downward from the right side (+X direction) end of the upper cover portion 253 and cover the gap from the right side (+X direction). The left cover portion 255 is configured to extend downward from the left side (-X direction) end of the upper cover portion 253 and cover the gap from the left side (+X direction). The upper cover portion 253 is mounted to the upper surface 231A using mounting holes 235. The right cover 254 is mounted to the right side 231R using mounting holes 235. The left cover 255 is mounted to the left side 231L using mounting holes 235.

[0086] The second cover 252 is a long, flat plate with the X direction as its length and the Z direction as its width, configured to cover the gap from below (in the -Y direction). The second cover 252 is mounted on the lower surface 231U using mounting holes 235. The gap S1 is covered from the outside by the first cover 251 and the second cover 252, thereby preventing contaminants from entering the gap from the outside.

[0087] (Shock absorber 270)

[0088] Figure 14 This diagram illustrates the position of the vibration dampers in an embodiment of the present invention. A plurality of (three in this case) vibration dampers 270 are disposed in the gap. Two of the three vibration dampers 270 are arranged symmetrically about the other vibration damper 270. The three vibration dampers 270 are respectively arranged in a state of compression in the depth direction (Z direction) by the fixing plate 230 and the panel base 104. Each vibration damper 270 has a large-diameter shaft portion 271 disposed at the center of the axial direction with the depth direction (Z direction) as its axis, a medium-diameter shaft portion 273 disposed on the front side (+Z direction) of the large-diameter shaft portion 271 with a diameter smaller than that of the large-diameter shaft portion 271, and a small-diameter shaft portion 275 disposed on the inner side (-Z direction) of the large-diameter shaft portion 271 with a diameter smaller than that of the medium-diameter shaft portion 273. The medium-diameter shaft portion 273 is formed of silicone material and abuts against the panel base 104 in a compressed state. Furthermore, the large-diameter shaft portion 271 serves as a base for receiving the medium-diameter shaft portion 273. The small-diameter shaft portion 275 is secured to the hole in the fixing plate 230 via threaded fixing and fitting (see reference). Figure 8 Therefore, the movement of the damper 270 in the X and Y directions is restricted.

[0089] The damper 270 is configured with the support portion 1B (fixed plate 230) and the supported portion 1C (panel base 104) in a compressed state in the depth direction (Z direction). In other words, the support portion 1B and the supported portion 1C are assembled in a state that applies pressure between the support portion 1B and the supported portion 1C. Thus, the damper 270 functions as a damping mechanism that dampens vibrations in both the pressing operation direction (-Z direction) and the actuator vibration direction (X direction).

[0090] like Figure 14 As shown, the parts where the supported part 1C and the supported part 1B are fixed or supported to each other (hereinafter referred to as the fixed points) are the two points where the supported part 1C and the supported part 1B are fixed to each other. When viewed from the side of the operation panel 101, when the operator applies a force greater than imagined to the edge side of the operation panel 101 in the vertical direction (Y direction), the supported part 1C wants to rotate about the straight line L2 connecting the two points as an axis. Since there is no fixed point arranged outside the straight line L2, the supported part 1C sometimes rotates about the straight line L2 as an axis.

[0091] Figure 15 This is a diagram showing the fixing points where the supported part 1C and the supporting part 1B are fixed or supported to each other in a comparative variation. For example... Figure 15 As shown, there are three fixed points. Two of the three points are arranged on the same straight line L1. One of the three points is arranged outside the straight line L1. For example, when the supported part 1C (operation panel 101, etc.) is to rotate about the straight line L1, the fixed point arranged outside the straight line L1 can suppress the rotation of the supported part 1C about the straight line L1. Furthermore, in this modified example, three fixed points are provided, and one of the three fixed points is arranged outside the same straight line, but the present invention is not limited to this. For example, more than three fixed points may be provided, and two or more of the three or more fixed points may be arranged outside the same straight line.

Figure 17 This is an assembly diagram of the connecting components and positioning plate according to an embodiment of the present invention. Figure 3 , Figure 5 , Figure 7 , Figure 16 and Figure 17As shown, a pair of positioning plates 310 are symmetrically arranged in the gap between the panel base 104 and the fixing plate 230. The positioning plate 310 on the left is designated as positioning plate 310L, and the positioning plate 310 on the right is designated as positioning plate 310R. Furthermore, a pair of connecting members 350 are symmetrically arranged in the gap between the panel base 104 and the fixing plate 230. The connecting member 350 on the left is designated as connecting member 350L, and the connecting member 350 on the right is designated as connecting member 350R.

[0094] like Figure 5 As shown, the supported portion 1C (panel base 104) is supported by the supported portion 1B (fixed plate 230) via the positioning plate 310R and the connecting member 350R. Furthermore, the supported portion 1C (panel base 104) is also supported by the supported portion 1B (fixed plate 230) via the positioning plate 310L and the connecting member 350L. In other words, the positioning plate 310R and the connecting member 350R, and the positioning plate 310L and the connecting member 350L, elastically support the supported portion 1C and position it. The support structure in which the supported portion 1C is supported by the positioning plate 310R and the connecting member 350R and the support structure in which the supported portion 1C is supported by the positioning plate 310L and the connecting member 350L are structurally identical, except for their left-right symmetry. In the following description, the support structure in which the supported part 1C is supported by the supported part 1B via the positioning plate 310R and the connecting member 350R will be used as an example for explanation, and the explanation of the support structure in which the supported part 1C is supported by the supported part 1B via the positioning plate 310L and the connecting member 350L will be omitted.

[0095] (Positioning plate 310)

[0096] The positioning plate 310R is a flat plate component with a generally rectangular shape, having a surface 311 facing the front side (+Z direction), a back side 313 facing the back side (-Z direction), a left edge 314 located at the left side (-X direction) end of the shape, and a right edge 315 located at the right side (+X direction) end of the shape.

[0097] In terms of shape, holes 316 and 317 are symmetrically arranged on the left and right sides. Hole 316 is a through hole that extends in the depth direction (Z direction) and is used for fixing the panel base 104 to the positioning plate 310R. Hole 317 is a through hole that extends in the depth direction (Z direction) and is used for fixing the positioning plate 310R to the connecting member 350R (the connecting member 350 disposed on the right side).

[0098] In its external shape, cutouts 318 and 319 are symmetrically arranged on the left and right sides. Cutout 319 is a cutout where the right edge 315 is cut into a semi-circular shape. Cutout 319 is a positioning cutout used to position the positioning plate 310R and the connecting member 350R to each other. Furthermore, the positioning plate 310R and the connecting member 350R are fixed using holes 317 and 394 and fasteners (e.g., bolts, nuts), using hole 394A (see reference). Figure 17 The 310R positioning plate and the connecting member 350R are positioned to each other by the cutout 319 and the positioning shaft-shaped member (e.g., positioning pin), which will be explained below.

[0099] Figure 18 This is a perspective view of the back of the positioning plate according to an embodiment of the present invention, viewed from an obliquely upward angle. Strain gauges 330 are disposed on the back 313 of each of the positioning plates 310R and 310L. The strain gauges 330 are positioned at the center in the left-right direction (X direction) and detect the strain of the positioning plate 310 after the operation panel 101 has been pressed in. The detection results of the strain gauges 330 are sent to an external device (e.g., a control unit not shown).

[0100] (Connecting component 350)

[0101] Figure 19 This is a perspective view of the front of the connecting member 350R located on the right side, viewed from an obliquely upward angle. The connecting member 350R has a leaf spring portion 370.

[0102] The leaf spring 370 elastically supports the operation panel 101 via the panel base 104. Specifically, the leaf spring 370 has a first elastic support 380A that can elastically support the operation panel 101 in the pressing operation direction (-Z direction), and a second elastic support 380B that can elastically support the vibration actuator 1 in the actuator vibration direction (X direction).

[0103] The first elastic support portion 380A has a first right-angle bend portion 390A whose shape is bent at a right angle to the flat surface facing the pressing operation direction (-Z direction). The first right-angle bend portion 390A has a Y-direction extension portion 391 extending in the vertical direction (Y direction), a lower left-direction extension portion 392 extending in the left direction (-X direction) from the lower end position of the Y-direction extension portion 391 (-Y direction), and an upper right-direction extension portion 393 extending in the right direction (+X direction) from the upper end position of the Y-direction extension portion 391 (+Y direction). That is, the shape of the first elastic support portion 380A has an L-shape that bends from the Y-direction extension portion 391 to the lower left-direction extension portion 392 and from the Y-direction extension portion 391 to the upper right-direction extension portion 393. Furthermore, the upper right-direction extension portion 393 is a connecting portion that connects to the second elastic support portion 380B.

[0104] The lower left-direction extension 392 is a connecting portion that connects to the positioning plate 310R. The lower left-direction extension 392 has holes 394 and 394A. Hole 394 is a fixing hole for securing the connecting member 350R to the positioning plate 310R. Hole 394A is a positioning hole for positioning the connecting member 350R and the positioning plate 310R to each other. When using fasteners (e.g....) Figure 17 When the connecting member 350R and the positioning plate 310R are fixed together by the bolt and nut shown, the bolt passes through holes 394 and 317. Thus, the positions of holes 394 and 317 are aligned. However, since the connecting member 350R and the positioning plate 310R can rotate relative to each other around the bolt, the positioning is incomplete. Therefore, a positioning shaft-like member (e.g., a positioning pin) is passed through hole 394A, and the outer periphery of the positioning pin is inserted into the notch 319. This restricts the relative rotation of the connecting member 350R and the positioning plate 310R around the bolt. In this manner, the connecting member 350R and the positioning plate 310R can be fixed to each other in a predetermined position.

[0105] The force in the pressing direction (-Z direction) of the operation panel 101 is transmitted to the panel base 104 and the positioning plate 310R, and further to the lower left extension 392, which is a connecting part connected to the positioning plate 310R. Furthermore, since the upper right extension 393 is a connecting part connected to the second elastic support 380B, the lower end of the Y-direction extension 391 flexes in the depth direction (Z direction) with its upper end as a fulcrum. In other words, the force in the pressing direction (-Z direction) of the operation panel 101 is absorbed by the flexing of the lower end of the Y-direction extension 391.

[0106] The second elastic support portion 380B has a second right-angle bend portion 390B whose shape is bent at a right angle to the flat surface facing the actuator vibration direction (X direction). The second right-angle bend portion 390B has a Y-direction extension portion 395 extending in the vertical direction (Y direction), a lower depth direction extension portion 396 extending in the depth direction (-Z direction) from the lower end position of the Y-direction extension portion 395 (-Y direction), and an upper front direction extension portion 397 extending in the front direction (+Z direction) from the upper end position of the Y-direction extension portion 395 (+Y direction). In other words, the shape of the second elastic support portion 380B has an L-shape that bends in an L-shape from the Y-direction extension portion 395 to the lower depth direction extension portion 396 and an L-shape that bends in an L-shape from the Y-direction extension portion 395 to the upper front direction extension portion 397. Furthermore, the end of the upper front extension 397 in the front direction (+Z direction) is connected to the end of the upper right extension 393 in the right direction (+X direction).

[0107] The inner end (-Z direction) of the lower depth extension 396 has two holes 398, one upper and one lower. Holes 398 are used for fixing the connecting member 350R to the fixing plate 230. The two holes 398 are respectively disposed in relation to the two holes 234 (see reference). Figure 1 The positions of the upper and lower holes 398 and 234 are respectively aligned. The nuts are tightened to the bolts passing through holes 398 and 234, so that the connecting part 350R and the fixing plate 230 can be fixed to each other in the predetermined position.

[0108] The force in the actuator vibration direction (X direction) that causes the operation panel 101 to vibrate by the vibration actuator 1 is transmitted to the panel base 104 and the positioning plate 310R, and further transmitted to the lower left extension 392, which is a connecting part connected to the positioning plate 310R. It is also transmitted to the Y direction extension 391, and further to the front end of the upper front extension 397, which is connected to the right (+X direction) end of the upper right extension 393. Furthermore, since the inner (-Z direction) end of the lower depth extension 396 is fixed to the fixing plate 230, the upper end of the Y direction extension 395 flexes in the left-right direction (X direction) with its lower end as a fulcrum. In other words, the force in the actuator vibration direction (X direction) is absorbed by the flexing of the upper end of the Y direction extension 395.

[0109] As described above, the support portion 1C (panel base 104) can be easily fixed to the positioning plate 310R (positioning plate 310 disposed on the right side) by using holes 109 and 316 and fasteners (bolts, nuts). Similarly, the panel base 104 can be easily fixed to the positioning plate 310L (positioning plate 310 disposed on the left side) by using holes 109 and 317 and fasteners (bolts, nuts).

[0110] Furthermore, by using holes 394, 316, 394A, cutout 319, fasteners (bolts, nuts), and shaft-shaped components (locating pins), the connecting member 350R (the connecting member 350 located on the right side) and the positioning plate 310R (the positioning plate 310 located on the right side) can be easily and accurately fixed to each other in a predetermined position. Similarly, by using holes 109, 317, 394A, cutout 318, fasteners (bolts, nuts), and shaft-shaped components (locating pins), the connecting member 350L (the connecting member 350 located on the left side) and the positioning plate 310L (the positioning plate 310 located on the left side) can be easily and accurately fixed to each other in a predetermined position.

[0111] Furthermore, by using the two holes 398 and 234, and fasteners (bolts, nuts), the connecting part 350R (the connecting part 350 located on the right side) and the fixing plate 230 can be easily and accurately fixed to each other in a predetermined position. Similarly, by using the two holes 398 and 234, and fasteners (bolts, nuts), the connecting part 350L (the connecting part 350 located on the left side) and the fixing plate 230 can be easily and accurately fixed to each other in a predetermined position.

[0112] The vibration presentation device 1A of the above embodiment includes a supported part 1C supported by a supported part 1B and on which a vibration actuator 1 is installed, a positioning plate 310 on which a strain gauge 330 is disposed, and a connecting member 350 having a leaf spring part 370. The supported part 1C is supported by the supported part 1B via the positioning plate 310 and the connecting member 350.

[0113] According to the above structure, the positioning plate 310 and the connecting member 350 can elastically support the supported part 1C and position the supported part 1C at a predetermined position. Therefore, the distance between the supporting part 1B and the supported part 1C is consistent with a predetermined distance, thus reducing costs associated with assembly and post-installation calibration. Furthermore, since the elastic support and positioning of the supported part 1C can be achieved through a simple structure, it is not necessary to complicate the shapes of the individual components of the positioning plate 310 and the connecting member 350, or the assembly structure of each component, thus reducing dependence on the size, structure, and shape of the operation panel 101. This, in turn, reduces manufacturing costs.

[0114] Furthermore, in the vibration presentation device 1A of the above embodiment, the positioning plate 310 has a support fixing hole 316 for fixing the positioning plate 310 to the support portion 1C, and a leaf spring fixing hole 317 for fixing the positioning plate 310 to the leaf spring portion 370. Thus, holes 316 and 317 are holes for assembling the positioning plate 310 to the support portion 1C and holes for assembling the leaf spring portion 370 to the positioning plate 310. Therefore, by manufacturing the position, size, etc. of the above holes as predetermined, the assembly accuracy when assembling the support portion 1C and the positioning plate 310, and the assembly accuracy when assembling the positioning plate 310 and the leaf spring portion 370, can be maintained at the desired accuracy.

[0115] The supported part 1C has an operation panel 101, and the vibration actuator 1 vibrates in a direction (X direction) orthogonal to the pressing operation direction (-Z direction) of the operation panel 101. Assuming that an actuator of the type that vibrates the operation panel 101 in a plane-perpendicular direction (Z direction) is installed, there is generally a tendency for the vibration noise to increase. In contrast, in this embodiment, the vibration actuator 1 vibrates in a direction orthogonal to the pressing operation direction, thus suppressing the vibration noise.

[0116] Furthermore, in the vibration presentation device 1A of the above embodiment, the strain gauge 330 detects the strain of the positioning plate 310 when the operation panel 101 is pressed in. During the pressing operation of the operation panel 101, the positioning plate 310 stretches or contracts. This causes a change in the resistance value of the strain gauge 330, and by measuring the resistance value, the operating load during the pressing operation of the operation panel 101 can be detected.

[0117] Furthermore, in the vibration presentation device 1A of the above embodiment, the leaf spring portion 370 has a first elastic support portion 380A capable of elastically supporting the operation panel 101 in the pressing operation direction, and a second elastic support portion 380B capable of elastically supporting the operation panel 101 in the actuator vibration direction of the vibration actuator 1. Thus, the first elastic support portion 380A elastically supports the operation panel 101, thereby generating a force (reaction force) that pushes it back relative to the pressing operation direction (-Z direction) of the operation panel 101, providing a tactile feedback to the user who has performed the pressing operation of the operation panel 101. Furthermore, since the second elastic support portion 380B elastically supports the supported portion 1C (operation panel 101, panel base 104), resonance driving of the supported portion 1C is possible. Moreover, by changing the size, shape, and thickness of the second elastic support portion 380B, the resonant frequency f1 of the first vibration system (refer to...) can be adjusted. Figure 13 ).

[0118] Furthermore, in the vibration presentation device 1A of the above embodiment, the first elastic support portion 380A has a first right-angled bend portion 390A whose outer shape is bent at a right angle to the flat surface facing the pressing operation direction, and the second elastic support portion 380B has a second right-angled bend portion 390B whose outer shape is bent at a right angle to the flat surface facing the actuator vibration direction. Therefore, for example, the portion of the first right-angled bend portion 390A extending in either of the bending directions can be used as the first elastic support portion 380A. The portion extending in the other direction can be used as a connection portion for connection with the positioning plate 310. Similarly, the portion of the second right-angled bend portion 390B extending in either of the bending directions can be used as the second elastic support portion 380B. The portion extending in the other direction can be used as a connection portion for connection with the support portion 1B (fixed plate 230).

[0119] Furthermore, in the vibration presentation device 1A of the above embodiment, the outer shape of the first right-angle bend 390A is one or more L-shaped shapes, and the outer shape of the second right-angle bend 390B is one or more L-shaped shapes. Therefore, at least one L-shaped shape can be used as the first right-angle bend 390A. And at least one L-shaped shape can be used as the second right-angle bend 390B. On the other hand, by constituting the first right-angle bend 390A with multiple L-shaped shapes, the spring constant of the first right-angle bend 390A is reduced, thus allowing adjustment of the spring constant. Furthermore, since the degree of freedom in the shape of the first right-angle bend 390A is increased, the assemblability of the connecting member 350 can be improved. Similarly, by constituting the second right-angle bend 390B with multiple L-shaped shapes, the spring constant of the second right-angle bend 390B is reduced, thus allowing adjustment of the spring constant. Furthermore, since the degree of freedom in the shape of the second right-angle bend 390B is increased, the assemblability of the connecting member 350 can be improved.

[0120] Furthermore, in the vibration presentation device 1A of the above embodiment, the support portion 1B and the supported portion 1C are assembled in a state where pressure is applied between the support portion 1B and the supported portion 1C, so as to function as a damping mechanism that dampens the supported portion 1C in both the pressing operation direction and the actuator vibration direction. For example, the damper 270 is configured with the supported portion 1B (fixed plate 230) and the supported portion 1C (panel base 104) compressed in the depth direction (Z direction). As a result, the vibration aftereffects of the supported portion 1C vibrating continuously for a longer period of time can be suppressed. Furthermore, external impacts on the supported portion 1C can be suppressed.

[0121] Furthermore, in the vibration presentation device 1A of the above embodiment, the fixing points where the support part 1C, the positioning plate 310, the connecting member 350, and the support part 1B are fixed together are two points. When viewed from the operation panel 101 side, if the operator applies a force greater than imagined to the edge side of the operation panel 101 in the vertical direction (Y direction), the support part 1C will want to rotate about the straight line L2 connecting the two points as an axis. Since there is no fixing point outside the straight line L2, the support part 1C sometimes rotates about the straight line L2 as an axis.

[0122] Furthermore, in the vibration presentation device 1D of the above-described modified example, there are three or more fixing points that fix the supported part 1C, the positioning plate 310, the connecting member 350, and the supported part 1B to each other. When at least two of the three or more fixing points are arranged on the same straight line, at least one of the three or more fixing points is arranged outside the same straight line. Thus, for example, when the supported part 1C (operation panel 101, etc.) is to rotate about the same straight line, the fixing points arranged outside the same straight line can suppress the rotation of the supported part 1C about the straight line L1.

[0123] Furthermore, in the vibration presentation device 1A of the above embodiment, the vibration actuator 1 has a fixed body 40 and a movable body 20 supported by the fixed body 40 and capable of free movement. When the vibration system including the support part 1B, the supported part 1C, and the fixed body 40 is designated as the first vibration system, and the vibration system including the supported part 1C, the fixed body 40, and the movable body 20 is designated as the second vibration system, the resonance frequency f1 of the first vibration system is higher than the resonance frequency f2 of the second vibration system. Therefore, in the vibration presentation device 1A where the first vibration system resonates at a frequency f1 higher than f2 if the second vibration system resonates at frequency f2, the resonance frequencies f1 and f2 can be set as the resonance frequencies of the first vibration system and the second vibration system, respectively.

[0124] Furthermore, in the vibration presentation device 1A of the above embodiment, the resonant frequency f1 of the first vibration system is 80 Hz or higher and 300 Hz or lower. A frequency of 80 Hz or higher and 300 Hz or lower is a frequency that is relatively easy for human sensory organs to perceive, thus allowing the user to easily perceive the vibration of the first vibration system.

[0125] Furthermore, in the vibration presentation device 1A of the above embodiment, the resonant frequency f2 of the second vibration system is 50 Hz or higher and lower than 80 Hz. Since the resonant frequency f2 is set to 50 Hz or higher, the vibration presentation device 1A mounted on a vehicle can be made unaffected by road noise (lower than 50 Hz) during vehicle operation. Moreover, since the resonant frequency f2 is lower than 80 Hz, in the vibration presentation device 1A where the resonant frequency f2 of the second vibration system is lower than the resonant frequency f1 of the first vibration system, when the resonant frequency f1 of the first vibration system is set to 80 Hz, a frequency lower than 80 Hz can be set as the resonant frequency of the second vibration system.

[0126] Furthermore, in the vibration presentation device 1A of the above embodiment, the frequency characteristics of the vibration actuator 1 are configured to be changeable within a predetermined range and determined based on the resonant frequency f2 of the second vibration system. Thus, for example, the resonant frequency of the second vibration system can be set based on the resonant frequency f2 of the second vibration system obtained through simulation.

[0127] Furthermore, in the vibration presentation device 1A of the above embodiment, the positioning plate 310 and the connecting member 350 are set as independent components, but they can also be set as an integral component. In this case, the supported part 1C is supported by the supported part 1B via the integral component. Moreover, the strain gauge 330 detects the strain of the integral component when the operation panel 101 is pressed in.

[0128] Furthermore, in the vibration presentation device 1A of the above embodiment, it is shown that the first elastic support portion 380A has a first right-angle bend portion 390A and the second elastic support portion 380B has a second right-angle bend portion 390B. However, the first elastic support portion 380A only needs to be able to elastically support the supported portion 1C (operation panel 101, etc.) in the pressing operation direction, and the second elastic support portion 380B only needs to be able to elastically support the supported portion 1C in the actuator vibration direction of the vibration actuator 1. The shapes of the first elastic support portion 380A and the second elastic support portion 380B are not limited and can be set to various shapes.

[0129] Furthermore, in the vibration presentation device 1A of the above embodiment, fasteners (bolts, nuts) are used to fix the panel base 104 to the positioning plate 310, the positioning plate 310 to the connecting member 350, and the connecting member 350 to the fixing plate 230, but rivets or other fixing components may also be used.

[0130] Furthermore, the above embodiments are merely illustrative examples of specific implementations of the present invention, and the technical scope of the present invention should not be limited by the above embodiments. That is, the present invention can be implemented in various forms without departing from its spirit or main features.

[0131] For example, in the above embodiment, the connecting member 350L and the connecting member 350R are configured as independent components forming a line-symmetrical shape (left-right reverse shape) with the length direction of the vibration actuator 1, that is, the left-right direction (X direction) as the center. However, instead of the connecting member 350R which is arranged on the right side (+X direction side) when viewed from the operation panel 101 side of the vibration actuator 1, the connecting member 350L, which is conventionally arranged on the left side (-X direction side) when viewed from the operation panel 101 side of the vibration actuator 1, is configured to rotate 180 degrees in the up-down direction (Y direction) when viewed from the operation panel 101 side of the vibration actuator 1, so that the connecting member 350 can be used as a component.
