[0005] Patent Document 1: Japanese Patent No. 3810920 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, the technology disclosed in Patent Document 1 is a structure in which the reset unit (dot) of the rubber sheet is pressed obliquely by tilting the push rod. Therefore, the dot is pressed obliquely downwards, and elastic deformation occurs while twisting. As a result, compared with a structure in which the dot is pressed straight downwards, fatigue is more likely to accumulate in a part of the dot. In addition, the dot may be locally damaged due to accumulated fatigue, and the life of the rubber sheet may be shortened.

[0047] Figure 1 This is a perspective view of the input device 100 according to one embodiment. Figure 2 This is a top view of an input device 100 according to one embodiment.

[0048] Figure 1 The input device 100 shown can be used, for example, as an input device for operating an electrically driven vehicle-mounted device (e.g., a power window) installed in a motor vehicle or similar vehicle. The input device 100 includes a frame 110 and an operating button 120 connected to and supported on the upper side of the frame 110 for rotation. For example, when the operating button 120 is rotated, the input device 100 generates a detection signal and sends this detection signal to a drive unit (not shown) of the power window, which is separately located from the input device 100. Upon receiving the detection signal, the drive unit actuates the power to open or close the vehicle window.

Figure 4 and Figure 5A This is a perspective view of the frame 110 of the input device 100 according to one embodiment. Figure 5B This is a bottom view of the frame 110 of the input device 100 according to one embodiment. Figure 5C The frame 110 of the input device 100 in one embodiment is placed in... Figure 5A The sectional view obtained by cutting at the cutting line EE shown. Figure 5D The frame 110 of the input device 100 in one embodiment is placed in... Figure 5A The sectional view obtained by cutting at the cutting line FF shown. Figure 6 This is a perspective view of the operation button 120 provided in the input device 100 according to one embodiment.

[0051] like Figure 3 As shown, the input device 100 includes an operation button 120, a frame 110, two cam members 170-1 and 170-2, four actuators 140-1 to 140-4, a rubber sheet 150, a base plate 160, and a cover 130.

[0052] <Operation Button 120>

[0053] The operating button 120 is a component that rotates in response to input from the operator. The operating button 120 is positioned above the frame 110 and is supported by its connection to the upper side (positive Z-axis side) of the frame 110, allowing it to rotate relative to the frame 110. The operating button 120 is a resin component that receives operating force from the operator. Figure 6 The bearing hole 121A shown is... Figure 3 The protrusion 111A of the frame 110 shown is connected, thereby supporting the operating button 120 so that it can rotate forward (positive X-axis direction) and backward (negative X-axis direction) relative to the frame 110. Figure 6 As shown, the operation button 120 has a hollow structure with an opening at the bottom. Additionally, as... Figure 6 As shown, in the internal space 120A of the operating button 120, a pair of left and right ribs 121 are arranged to hang down from the top surface of the internal space 120A. Each pair of ribs 121 has a circular bearing hole 121A that extends through the rib 121 in the left-right direction.

[0054] like Figure 6As shown, within the internal space 120A of the operating button 120, a pressing part 122-1 is provided protruding downwards from the top surface of the internal space 120A, located forward (on the positive X-axis side) of the pair of ribs 121. When the operating button 120 is rotated forward (in the positive X-axis direction), the pressing part 122-1 presses against the cam member 170-1 disposed below it. The pressing part 122-1 is positioned offset to the left from the center of the operating button 120 in the left-right direction. The pressing part 122-1 is the part that transmits the operating force by pressing the cam member 170-1 when the operating button 120 is rotated.

[0055] like Figure 6 As shown, within the internal space 120A of the operating button 120, a pressing part 122-2 is provided protruding downwards from the top surface of the internal space 120A, located rearwards (on the negative X-axis side) from the pair of ribs 121. When the operating button 120 is rotated rearwards (in the negative X-axis direction), the pressing part 122-2 presses against the cam member 170-2 disposed below it. The pressing part 122-2 is positioned offset to the right from the center of the operating button 120 in the left-right direction. The pressing part 122-2 is the portion that transmits the operating force by pressing the cam member 170-2 when the operating button 120 is rotated.

[0056] <Frame 110>

[0057] The frame 110 is a container-shaped resin component with a hollow structure. A rubber sheet 150, a base plate 160, and a cover 130 are housed inside the frame 110. A wall portion 111 with a generally square cylindrical shape, extending vertically, is formed on the upper part of the frame 110. The wall portion 111 has an upper opening 111B. The upper opening 111B is covered by the operating button 120 after assembly. The wall portion 111 has a pair of protrusions 111A projecting from the inner wall surfaces on both the left and right sides. The protrusions 111A have a shape corresponding to the bearing holes 121A of the operating button 120 and are positioned corresponding to the bearing holes 121A. By engaging with the pair of bearing holes 121A respectively, the wall portion 111 supports the operating button 120, allowing it to rotate in the front-back direction (X-axis direction).

[0058] like Figure 4 and Figures 5A to 5DAs shown, the frame 110 has two beams 115 (115-1, 115-2) on the inner side of the wall 111. Beam 115-1 is located on the front side (positive X-axis side), supported by the wall of the support operating button 120, and extends in the left-right direction (Y-axis direction). Beam 115-2 is located on the rear side (negative X-axis side), supported by the wall of the support operating button 120, and extends in the left-right direction (Y-axis direction). Both beams 115-1 and 115-2 have a plate-like shape, designed to elastically deform in the X-axis direction.

[0059] The frame 110 has two first support holes 112-1 and 112-2 on the inner side of the wall portion 111. The two first support holes 112-1 and 112-2 are each approximately square-cylindrical in shape with the vertical direction as the cylindrical direction. A portion of the front first support hole 112-1 is formed by a beam portion 115-1, which can temporarily change its front-to-back (X-axis) dimension in response to the elastic deformation of the beam portion 115-1. Furthermore, the cam member 170-1 is configured such that the front-to-back (X-axis) dimension of the engaging protrusion 172 is larger than the dimension of the first support hole 112-1 before elastic deformation and smaller than the dimension of the first support hole 112-1 after elastic deformation. The first support hole 112-1 is a hole through which the engaging protrusion 172 of the front cam member 170-1 is inserted from above when the cam member 170-1 is assembled with the frame 110. Figure 4 As shown, at the upper front end of the beam portion 115-1 that forms the entrance portion of the first support hole 112-1, a chamfered shape (snap-in inclined portion 117) is provided to facilitate the engagement protrusion 172 from above. A portion of the rear first support hole 112-2 is formed by the beam portion 115-2, and its dimensions in the front-rear direction (X-axis direction) can be temporarily changed in accordance with the elastic deformation of the beam portion 115-2. The rear first support hole 112-2 is a hole for the engagement protrusion 172 of the rear cam member 170-2 to be inserted from above. At the upper rear end of the beam portion 115-2 that forms the entrance portion of the first support hole 112-2, a chamfered shape (snap-in inclined portion 117) is provided to facilitate the engagement protrusion 172 from above.

[0060] The frame 110 has four second support holes 113-1 to 113-4 on the inner side of the wall portion 111. Each of the four second support holes 113-1 to 113-4 is approximately cylindrical with the vertical direction as the cylindrical direction. The two front second support holes 113-1 and 113-2 are located in the beam portion 115-1, sandwiching the first support hole 112-1 in the middle and arranged in the left-right direction. The two front second support holes 113-1 and 113-2 each have a shaft portion 141 passing through from the bottom side to support the two front actuators 140-1 and 140-2, respectively. The two rear second support holes 113-3 and 113-4 are located in the beam portion 115-2, sandwiching the first support hole 112-2 in the middle and arranged in the left-right direction. The two rear-side second support holes 113-3 and 113-4 each support the two rear-side actuators 140-3 and 140-4 respectively, through which the shaft portions 141 of the two rear-side actuators 140-3 and 140-4 pass from below. Figure 4 The guide portion 118 shown is configured to support the shaft portion 141 of the actuator 140 in a shape that allows it to slide up and down, and is located below the main body portion 171 of the cam member 170 after the frame 110 and the cam member 170 are assembled.

[0061] <Actuators 140-1 to 140-4>

[0062] Four actuators 140-1 to 140-4 are supported by the frame 110 and are capable of sliding in a direction perpendicular to the substrate (vertical direction). The four actuators 140-1 to 140-4 are respectively disposed on the upper side of the four rounded tops 152-1 to 152-4 of the rubber sheet 150. Each of the four actuators 140-1 to 140-4 is a resin component having a cylindrical shaft portion 141 extending in the vertical direction (Z-axis direction) and a horizontal circular pressing portion 142. The pressing portion 142 is located at the lower end of the shaft portion 141. During a rotational operation based on the operating button 120, the four actuators 140-1 to 140-4 are pressed down by either the cam member 170-1 or the cam member 170-2. As a result, the four actuators 140-1 to 140-4 slide downwards respectively, pressing the top 152 of the rubber sheet 150 located below the pressing part 142 by the bottom surface of the pressing part 142.

[0063] It should be noted that the actuator 140-1 slides toward the first switch (round top 152-1 and fixed contact 161-1) in response to the first action of the cam member 170-1, pressing the first switch. The actuator 140-1 is an example of a "first actuator".

[0064] Furthermore, after the first action of the cam member 170-1 is completed and a further operating force is applied, the actuator 140-2 slides toward the second switch (dot 152-2 and fixed contact 161-2) in response to the second action attached to the first action, pressing the second switch. The actuator 140-2 is an example of a "second actuator".

[0065] Furthermore, after the first action of the cam member 170-2 is completed and a further operating force is applied, the actuator 140-3 slides toward the second switch (dot 152-3 and fixed contact 161-3) in response to the second action attached to the first action, pressing the second switch. The actuator 140-3 is an example of a "second actuator".

[0066] Additionally, actuator 140-4 slides toward the first switch (dot 152-4 and fixed contact 161-4) in response to the first action of cam member 170-2, pressing the first switch. Actuator 140-4 is an example of a "first actuator".

[0067] <Cam component 170-1>

[0068] The cam member 170-1 is a resin component disposed inside the front side (X-axis positive side) of the frame 110 and supported by the frame 110, capable of sliding in the vertical direction and swinging in the horizontal direction. The cam member 170-1 has a main body 171, which is elongated in the horizontal direction (Y-axis direction). The main body 171 is disposed above the two actuators 140-1 and 140-2 on the front side. The main body 171 is configured to be suspended above the tops of each of the two actuators 140-1 and 140-2. A locking protrusion 172 is provided protruding downwards from the center of the bottom surface of the main body 171 in the horizontal direction.

[0069] The cam member 170-1 is supported by the frame 110 by inserting the engaging protrusion 172 into the first support hole 112-1 located on the front side of the frame 110 from above. When the operating button 120 is rotated forward (in the positive X-axis direction), the lower end of the pressing part 122-1 on the front side of the operating button 120 presses the upper surface of the main body 171 of the cam member 170-1 to a position biased to the left.

[0070] When the rotation amount of the operating button 120 forward (positive X-axis direction) is within a predetermined first angle range, as a first action, the cam member 170-1 swings to the left, pressing the left actuator 140-1. The actuator 140-1, pressed by the cam member 170-1, presses down the left rounded top 152-1, causing it to elastically deform. As a result, the left fixed contact 161-1 becomes conductive. In this embodiment, the first angle range refers to... Figure 13 The angle (0°) [deg] of the operation button 120 in the non-operational state shown after automatic recovery is indicated is used as a reference. Any angle larger than this and [the angle is not specified in the original text]. Figure 14 The angle range below 7° [deg] for the operating button 120 shown. The first angle range is 0° [deg] < θ ≤ 7° [deg]. When the operating button 120 rotates forward (positive X-axis direction) by 7° [deg], as... Figure 17 As shown, the left fixed contact 161-1 of the two fixed contacts 161 arranged in the left-right direction is in the conducting state.

[0071] When the rotation amount of the operating button 120 forward (positive X-axis direction) is within a predetermined second angle range (> the first angle range), as a second action, the cam member 170-1, while maintaining the left actuator 140-1 pressed, swings to the right, thus becoming horizontal, and further presses down the right actuator 140-2. The actuator 140-2, pressed down by the cam member 170-1, presses down the right rounded top 152-2, causing it to elastically deform. As a result, the right fixed contact 161-2 becomes conductive. In this embodiment, the second angle range refers to... Figure 14 The angle (7°) of the operation button shown is large and is... Figure 15 The angle range shown is below 14° [deg] for the operating button 120. The second angle range is 7° [deg] < θ ≤ 14° [deg]. When the operating button 120 is rotated 14° [deg] forward (positive X-axis direction), as shown... Figure 18 As shown, the two fixed contacts 161-1 and 161-2, arranged in the left-right direction, are both in the conductive state.

[0072] Here, actuators 140-1 and 140-2 are supported so that they can slide in the vertical direction. Therefore, by pressing actuators 140-1 and 140-2 down by cam member 170-1, the dome 152-1 and 152-2 can be pressed straight down.

[0073] When the forward (positive X-axis direction) rotation of the operating button 120 is released, the cam member 170-1 and the operating button 120 return to the neutral state by means of the restoring force from the two domes 152-1 and 152-2.

[0074] <Cam component 170-2>

[0075] The cam member 170-2 is a resin component disposed inside the rear side (negative X-axis side) of the frame 110 and supported by the frame 110, capable of sliding vertically and swinging horizontally. The cam member 170-2 has a main body 171, which is elongated in the horizontal direction (Y-axis direction). The main body 171 is disposed above the two rear actuators 140-3 and 140-4. The main body 171 is configured to be suspended above the tops of the two actuators 140-3 and 140-4. A locking protrusion 172 is provided downwardly at the center of the bottom surface of the main body 171 in the horizontal direction.

[0076] The cam member 170-2 is supported by the frame 110 by inserting the engaging protrusion 172 into the first support hole 112-2 located on the rear side of the frame 110 from above. When the operating button 120 is rotated rearward (in the negative X-axis direction), the lower end of the pressing part 122-2 on the rear side of the operating button 120 presses the upper surface of the main body 171 of the cam member 170-2 to a position biased to the right.

[0077] When the operation button 120 is rotated rearward (in the negative X-axis direction) to a predetermined first angle range, as a first action, the cam member 170-2 swings to the right, pressing the right actuator 140-4. The actuator 140-4, pressed by the cam member 170-2, presses down on the right rounded top 152-4, causing it to elastically deform. As a result, the right fixed contact 161-4 becomes conductive. In this embodiment, the first angle range is 0° [deg] < θ ≤ 7° [deg]. When the operation button 120 is rotated rearward (in the negative X-axis direction) by 7° [deg], the right fixed contact 161-4 of the two fixed contacts 161 arranged in the left-right direction becomes conductive.

[0078] When the operation amount of the operation button 120 is rotated rearward (in the negative X-axis direction) within a predetermined second angle range (> the first angle range), as a second action, the cam member 170-2, while maintaining the right actuator 140-4 pressed, swings to the left to become horizontal, and further presses down the left actuator 140-3. The actuator 140-3, pressed down by the cam member 170-2, presses down the left rounded top 152-3, causing it to elastically deform. As a result, the left fixed contact 161-3 becomes conductive. In this embodiment, the second angle range is 7° [deg] < θ ≤ 14° [deg]. When the operation button 120 is rotated rearward (in the negative X-axis direction) by 14° [deg], both fixed contacts 161-3 and 161-4, arranged in the left-right direction, become conductive.

[0079] Here, actuators 140-3 and 140-4 are supported so that they can slide in the vertical direction. Therefore, by pressing actuators 140-3 and 140-4 down by cam member 170-2, the dome 152-3 and 152-4 can be pressed straight down.

[0080] When the operation of the control button 120 in the rearward (negative X-axis direction) is released, the cam member 170-2 and the control button 120 return to the neutral state by means of the restoring force from the two domes 152-3 and 152-4.

[0081] <Substrate 160>

[0082] The substrate 160 is a flat component made of rigid resin. The substrate 160 is placed inside the frame 110 on the upper surface 130A of the cover 130 and is arranged parallel to the XY plane direction. For example, a PWB (Printed Wiring Board) is used as the substrate 160.

[0083] Four fixed contacts 161-1 to 161-4 are arranged in a 2×2 matrix on the upper surface 160A of the substrate 160. All four fixed contacts 161-1 to 161-4 have a generally circular shape when viewed from above along the Z-axis. Each of the four fixed contacts 161-1 to 161-4 is formed using a thin, conductive metal material (e.g., copper film).

[0084] <Rubber Sheet 150>

[0085] The rubber sheet 150 is a flat plate-shaped component formed using an elastic material (such as silicone, rubber, etc.). The rubber sheet 150 covers the substrate 160 inside the frame 110 and is positioned parallel to the XY plane. The rubber sheet 150 protects the substrate 160 from water droplets and the like. The rubber sheet 150 has a base 151 and four rounded tops 152-1 to 152-4.

[0086] The base 151 is a horizontal, flat plate-like portion that has a rectangular shape when viewed from above along the Z-axis. The base 151 supports four rounded tops 152-1 to 152-4.

[0087] The four dome-shaped sections 152-1 to 152-4 are dome-shaped and protrude upwards from the upper surface 151A of the base 151. Each of the four dome-shaped sections 152-1 to 152-4 is positioned to overlap with the four fixed contacts 161-1 to 161-4 provided on the substrate 160 when viewed from above. That is, the four dome-shaped sections 152-1 to 152-4 are arranged in a 2×2 matrix on the rubber sheet 150.

[0088] Movable contacts (not shown) are provided on the lower side (negative Z-axis side) of each of the four dome shapes 152-1 to 152-4. When the operating button 120 is rotated, the actuators 140 located on the upper side (positive Z-axis side) of each dome shape 152 are pressed down, causing them to bend downwards (in the negative Z-axis direction) (elastic deformation) and come into contact with the fixed contact 161 located on the lower side (negative Z-axis side) of the dome shape 152. Thus, the fixed contact 161 contacts the movable contact 152A, becoming conductive. The dome shape 152 has a restoring force, returning to its initial state when the operating force is released.

[0089] The dome 152-1, together with the fixed contact 161-1, constitutes a "first switch" and a "rubber dome switch" that are turned on in response to the first action of the cam member 170-1. The dome 152-2, together with the fixed contact 161-2, constitutes a "second switch" and a "rubber dome switch" that are turned on in response to the second action of the cam member 170-1.

[0090] The dome 152-3, together with the fixed contact 161-3, constitutes a "second switch" and a "rubber dome switch" that are turned on in response to the second action of the cam member 170-2. The dome 152-4, together with the fixed contact 161-4, constitutes a "first switch" and a "rubber dome switch" that are turned on in response to the first action of the cam member 170-2.

[0091] It should be noted that the "first switch" and "second switch" are not limited to the "rubber dome switch", but can also be other switches (e.g., metal contact switch, etc.).

[0092] <Cover 130>

[0093] The cover 130 is a resin component that closes the lower opening 110A of the frame 110 by being embedded in it. The cover 130 has a generally cuboid shape. A substrate 160 is mounted on the upper surface 130A of the cover 130. A plurality of engaging claws 131 are provided on the side of the cover 130. The cover 130 is fixed to the frame 110 by engaging the plurality of engaging claws 131 with the plurality of openings 114 formed on the side of the frame 110.

Figure 18 This is a cross-sectional view of the locking portion (top 172Aa) and the swing fulcrum portion (top 115Aa) of an input device 100 in one embodiment, where the operation button 120 is rotated to the end of the second angle range. Figure 19 This is a cross-sectional view of an input device according to one embodiment, based on the JJ section line.

[0096] like Figures 11A to 11E As shown, cam member 170-1 and cam member 170-2 are respectively provided with engaging protrusions 172 protruding downward from the center of the bottom surface of the main body 171 in the left-right direction (Y-axis direction).

[0097] like Figures 11A to 11E As shown, the engaging protrusion 172 has protrusions 172A extending forward (positive X-axis direction) and backward (negative X-axis direction) from the main body 171, respectively. Therefore, the width of the engaging protrusion 172 in the front-rear direction (X-axis direction) is greater than the width of the main body 171 in the front-rear direction (X-axis direction).

[0098] When viewed from above in the X-axis direction, the protrusion 172A has an isosceles triangular shape with the upper end becoming the top 172Aa (i.e., a shape that tapers upwards). That is, the top 172Aa of the protrusion 172A is located at the center in the left-right direction (Y-axis direction) of the cam member 170-1 and the cam member 170-2.

[0099] The width of the engagement protrusion 172 of the cam member 170-1 in the front-back direction (X-axis direction) is greater than the width of the upper opening of the first support hole 112-1 (the part provided with the limiting wall 115A described later) in the front-back direction (X-axis direction).

[0100] Therefore, in the input device 100 of one embodiment, by pushing the engaging protrusion 172 of the cam member 170-1 into the first support hole 112-1 from the upper opening of the first support hole 112-1, the beam portion 115-1 can be elastically deformed to expand the width of the upper opening of the first support hole 112-1 in the front-back direction, and the engaging protrusion 172 of the cam member 170-1 can be easily embedded into the first support hole 112-1.

[0101] Furthermore, in one embodiment of the input device 100, the width of the engaging protrusion 172 of the cam member 170-1 embedded in the first support hole 112-1 in the front-rear direction (X-axis direction) is larger than the upper opening of the first support hole 112-1. Therefore, in one embodiment of the input device 100, the upward movement of the cam member 170-1 can be stopped by making the top 172Aa of the protrusion 172A of the cam member 170-1 abut against the lower surface of the limiting wall 115A provided in the upper opening of the first support hole 112-1, thereby making it difficult for the cam member 170-1 to fall out of the first support hole 112-1.

[0102] That is, the top 172Aa of the engaging protrusion 172 of the cam member 170-1 constitutes a "locking part capable of insertion and locking".

[0103] like Figures 11A to 11E and Figure 19 As shown, the cam member 170-1 has a sliding portion 173 disposed on the positive X-axis side and the negative X-axis side of the main body 171. The sliding portion 173 is slidable relative to the guide surface 116, the details of which will be described later. The sliding portion 173 has a planar shape parallel to the YZ plane. The frame 110 includes a guide surface 116 having a planar shape parallel to the YZ plane and disposed opposite to the sliding portion 173. After the engaging protrusion 172 is inserted into the first support hole 112-1, the cam member 170-1 is guided in the YZ plane direction by the guide surface 116 via the sliding portion 173. Thus, the cam member 170-1 is supported between the wall portion on the front side (positive X-axis side) and the wall portion on the rear side (negative X-axis side) of the beam portion 115-1, allowing it to swing in the left-right direction (Y-axis direction). It should be noted that the width of the main body 171 of the cam member 170-1 in the front-rear direction (X-axis direction) and the distance between the inner wall surface of the front side (positive X-axis side) and the inner wall surface of the rear side (negative X-axis side) of the beam 115-1 are approximately equal. Therefore, the cam member 170-1 can oscillate in the left-right direction (Y-axis direction) while suppressing wobbling in the front-rear direction (X-axis direction).

[0104] Similarly, the width of the engagement protrusion 172 of the cam member 170-2 in the front-back direction (X-axis direction) is greater than the width of the upper opening of the first support hole 112-2 (the part provided with the limiting wall 115A described later) in the front-back direction (X-axis direction).

[0105] Therefore, in the input device 100 of one embodiment, by pushing the engaging protrusion 172 of the cam member 170-2 into the first support hole 112-2 from the upper opening of the first support hole 112-2, the beam portion 115-2 can be elastically deformed to expand the width of the upper opening of the first support hole 112-2 in the front-back direction, and the engaging protrusion 172 of the cam member 170-2 can be easily embedded into the first support hole 112-2.

[0106] Furthermore, in one embodiment of the input device 100, the width of the engaging protrusion 172 of the cam member 170-2 embedded in the first support hole 112-2 in the front-rear direction (X-axis direction) is larger than the upper opening of the first support hole 112-2. Therefore, in one embodiment of the input device 100, upward movement can be stopped by abutting the top 172Aa of the protrusion 172A of the cam member 170-2 against the lower surface of the limiting wall 115A provided in the upper opening of the first support hole 112-2, thereby making it difficult for the cam member 170-2 to fall out of the first support hole 112-2.

[0107] That is, the engaging protrusion 172 of the cam member 170-2 and the limiting wall 115A of the first support hole 112-2 are in an insert-locking shape. The top 172Aa of the engaging protrusion 172 is an example of a "locking part". The top 115Aa of the limiting wall 115A is an example of a "swinging fulcrum part".

[0108] The cam member 170-2 has a sliding portion 173 disposed on the positive X-axis side and the negative X-axis side of the main body 171. The sliding portion 173 has a planar shape parallel to the YZ plane. The frame 110 includes a guide surface 116 having a planar shape parallel to the YZ plane and disposed opposite to the sliding portion 173. After the engaging protrusion 172 is inserted into the first support hole 112-2, the cam member 170-2 is guided in the YZ plane direction by the guide surface 116 through the sliding portion 173. Thus, the cam member 170-2 is supported between the wall portion on the front side (positive X-axis side) of the beam portion 115-2 and the wall portion on the rear side (negative X-axis side) of the beam portion 115-2, allowing it to swing in the left-right direction (Y-axis direction). It should be noted that the width of the main body 171 of the cam member 170-2 in the front-rear direction (X-axis direction) and the distance between the inner wall surface of the front side (positive X-axis side) and the inner wall surface of the rear side (negative X-axis side) of the beam 115-2 are approximately equal. Therefore, the cam member 170-2 can oscillate in the left-right direction (Y-axis direction) while suppressing wobbling in the front-rear direction (X-axis direction).

[0109] It should be noted that, in one embodiment, the input device 100, as shown... Figure 7B , Figures 11A to 11C and Figure 11E As shown, the engaging protrusions 172 of each of the cam members 170-1 and 170-2 have a tapered shape (insertion inclined portion 174) whose width gradually narrows downward in the front-rear direction (X-axis direction). Furthermore, the width of the cam members 170-1 and 170-2 in the front-rear direction (X-axis direction) at their lower ends is smaller than the upper opening of the first support hole 112-1 and the upper opening of the first support hole 112-2. Therefore, the input device 100 of one embodiment can easily perform positioning when inserting the cam members 170-1 and 170-2 into the first support holes 112-1 and 112-2. Additionally, as... Figure 4 and Figure 5C As shown, the beam portion 115-1 constituting the first support hole 112-1 and the beam portion 115-2 constituting the first support hole 112-2 are provided with a tapered shape (insertion inclined portion 117) that is substantially parallel to the insertion inclined portion 174. Therefore, after positioning, the beam portion 115-1 and the beam portion 115-2 can be easily elastically deformed to perform the assembly operation of inserting the cam member 170-1 and the cam member 170-2 into the first support hole 112-1 and the first support hole 112-2. It should be noted that, as Figure 4As shown, a guide portion 118 constituting the second support holes 113-1 to 113-4 is provided below the main body portion 171 of the cam member 170 at a position overlapping the main body portion 171 in the Z-axis direction. Therefore, after insertion and connection, even assuming that the cam member 170 is not subjected to a restoring force from the dome 152, it will not fall off the frame 110 because it is supported by the contact between the main body portion 171 and the guide portion 118.

[0110] like Figures 5A-5B , Figure 7B , Figure 9 , Figures 16-18As shown, a limiting wall 115A is provided at the edge of the upper opening of the first support hole 112-1, on the rear side (negative side of the X-axis), protruding into the first support hole 112-1. The lower surface of the limiting wall 115A has a groove in the shape of an isosceles triangle that tapers upwards. The top 172Aa of the protrusion 172A of the cam member 170-1 has a curved shape and abuts (face contact) from below with the top 115Aa, which is a curved surface on the lower surface of the limiting wall 115A and has a curvature greater than that of the top 172Aa. Thus, the cam member 170-1 is accurately positioned at the center in the left-right direction (Y-axis direction) inside the wall portion 111 of the frame 110. Furthermore, by the contact between the top 172Aa and the top 115Aa of the lower surface of the limiting wall 115A, the cam member 170-1 can swing in the left-right direction (Y-axis direction) with the top 115Aa as the "swing fulcrum". It should be noted that in this embodiment, the structure of the "swing fulcrum" and the "locking part" in surface contact is described. However, the "swing fulcrum" and the "locking part" can be structures with low frictional force generated when the cam member 170 begins to swing, and they do not necessarily have to be curved surfaces in surface contact. That is, the "swing fulcrum" and the "locking part" can also be point contact or line contact structures. In addition, in this embodiment, when viewed from the X-axis direction, the top 115Aa and the first tapered part 115Ab constituting the limiting wall 115A have a concave top shape, with the top 115Aa as the vertex of the concave angle and the first tapered part 115Ab on both sides thereon. The first tapered part 115Ab is provided on both sides of the top 115Aa in the Y-axis direction in such a way that the top 115Aa is sandwiched between them. Furthermore, when viewed from the X-axis direction, the top 172Aa and the second conical portion 172Ab of the protrusion 172A constituting the engaging protrusion 172 have a convex angle at the top, with the top 172Aa as the vertex and the second conical portion 172Ab on both sides thereon. The second conical portions 172Ab are provided on both sides of the top 172Aa in the Y-axis direction such that they sandwich the top 172Aa between them. Specifically, in this embodiment, the angle of the concave angle formed by the pair of first conical portions 115Ab is formed to be 90° [deg], and the angle of the convex angle formed by the pair of second conical portions 172Ab is formed to be 70° [deg]. Therefore, when the operating button 120 is released from the state operated by the operator and returns to the initial state due to the restoring force from the dome 152, the top 172Aa of the cam member 170 contacts the limiting wall 115A. Then, the cam member 170 slides on the first tapered portion 115Ab until the top 172Aa abuts against the top 115Aa, thereby returning to the initial position.

[0111] Similarly, a limiting wall 115A is provided protruding into the first support hole 112-2 at the edge of the upper opening (positive X-axis side). The lower surface of the limiting wall 115A has a groove in the shape of an isosceles triangle that tapers upward. The top 172Aa of the protrusion 172A of the cam member 170-2 abuts (face contact) with the top 115Aa of the lower surface of the limiting wall 115A from below. Thus, the cam member 170-2 is accurately positioned at the center in the left-right direction (Y-axis direction) inside the wall portion 111 of the frame 110. In addition, by the top 172Aa abutting with the top 115Aa of the lower surface of the limiting wall 115A, the top 172Aa and the top 115Aa become fulcrums, thereby allowing the cam member 170-2 to swing in the left-right direction (Y-axis direction).

[0112] It should be noted that in the input device 100 of one embodiment, when the operating button 120 is released from the operating force after being rotated, the cam members 170-1 and 170-2 are subjected to equal upward force from the left and right sides by the restoring force of the two round tops 152, thereby restoring them to a horizontal state. At this time, since the top 172Aa is pressed against the top 115Aa of the lower surface of the limiting wall 115A, the cam members 170-1 and 170-2 can maintain a state in which they are accurately positioned in the center in the left-right direction (Y-axis direction). It should be noted that in the input device 100 of one embodiment, by accurately positioning the cam members 170-1 and 170-2 in the center in the left-right direction (Y-axis direction), for example, it is possible to prevent the sides of the cam members 170-1 and 170-2 in the left-right direction (Y-axis direction) from abutting against the inner wall surface of the wall portion 111 of the frame 110 during the swinging action, thus preventing them from being ground or becoming a resistance.

[0113] (Assembly method of input device 100)

[0114] The following is for reference Figures 12A to 12G The steps of assembling the input device 100 according to one embodiment will be described. Figures 12A to 12G This is a diagram illustrating the steps of assembling an input device 100 according to one embodiment.

[0115] First, such as Figure 12A and Figure 12B As shown, the substrate 160 is placed on the upper surface 130A of the cover 130. Then, as... Figure 12C As shown, a rubber sheet 150 is overlapped on the upper surface of the substrate 160.

[0116] Next, as Figure 12D As shown, four actuators 140-1 to 140-4 are respectively mounted on the upper surface of the four round tops 152-1 to 152-4 of the rubber sheet 150.

[0117] Next, as Figure 12E As shown, the lower opening 110A of the frame 110 is inserted from above relative to the cover 130.

[0118] Next, as Figure 12F As shown, the cam components 170-1 and 170-2 are assembled into the frame 110 by inserting their respective engaging protrusions 172 into the support holes of the first support holes 112-1 and 112-2 of the frame 110 from above.

[0119] Finally, as Figure 12G As shown, the operation button 120 is mounted on the frame 110 by inserting each of the pair of bearing holes 121A of the operation button 120 into the pair of protrusions 111A of the frame 110 from above.

[0120] Thus, in one embodiment of the input device 100, the input device 100 can be assembled by sequentially stacking multiple components. That is, in one embodiment of the input device 100, the assembly of the input device 100 can be completed relatively easily without reversing any components.

[0121] An input device 100 according to one embodiment includes: a frame 110; an operation button 120 supported on the frame 110 and rotating upon receiving an operating force from an operator; cam members 170-1 and 170-2 configured to swing in an oscillating direction intersecting the rotation direction of the operation button 120, and to perform a first action by oscillation when the operation button 120 rotates within a first angular range, and a second action by oscillation when the operation button 120 rotates within a second angular range following the first angular range; a first switch that is turned on in response to the first action; and a second switch that is turned on in response to the second action. The input device 100 automatically recovers upon release from the operating force by means of a restoring force from the first and second switches. The input device 100 also includes: actuators 140-1 and 140-4 that slide toward the first switch in response to the first action; and actuators 140-2 and 140-3 that slide toward the second switch in response to the second action.

[0122] Thus, the input device 100 of one embodiment can press the first switch and the second switch vertically downwards via actuators 140-1, 140-4 and actuators 140-2, 140-3, thereby suppressing the occurrence of malfunctions of the first switch and the second switch.

[0123] In one embodiment of the input device 100, the cam members 170-1, 170-2 and the frame 110 have a locking portion (top 172Aa) capable of being inserted and locked, the locking portion having the shape of a convex apex.

[0124] Thus, the input device 100 of one embodiment can easily assemble the cam members 170-1 and 170-2 into the frame 110. In addition, the input device 100 of one embodiment can prevent the cam members 170-1 and 170-2 from falling off the frame 110 after they are assembled into the frame 110.

[0125] In addition, in one embodiment of the input device 100, in the non-operational state, the locking part (top 172Aa) maintains a swingable state and abuts against the swing fulcrum part (top 115Aa) which has a concave apex shape.

[0126] Therefore, the locking portion of the input device 100 in one embodiment has a shape that fulfills both the function of being able to be inserted and the function of serving as a fulcrum when the operation button 120 swings. As a result, the structure of these two functions can be simplified.

[0127] In addition, in one embodiment of the input device 100, the frame 110 has: a wall portion 111 that supports the operation button 120; and beam portions 115-1 and 115-2 that are supported on the wall portion 111 and extend in a direction intersecting the rotation direction of the operation button 120. The swing fulcrum portion (top 115Aa) of the frame 110 is provided on the beam portions 115-1 and 115-2.

[0128] Thus, in the input device 100 of one embodiment, by elastically deforming the beams 115-1 and 115-2, the cam members 170-1 and 170-2 can be easily assembled into the frame 110.

[0129] In addition, in one embodiment of the input device 100, the beams 115-1 and 115-2 have a plate shape and are configured to be elastically deformable.

[0130] Thus, in the input device 100 of one embodiment, by elastically deforming the beams 115-1 and 115-2, the cam members 170-1 and 170-2 can be easily assembled into the frame 110.

[0131] It should be noted that, in one embodiment of the input device 100, when viewed from above in the Z-axis direction, the first switch and the second switch are located inside the outer edge of the operation button 120 and are configured to overlap with the operation button 120.

[0132] In addition, in one embodiment of the input device 100, when viewed from above in the Z-axis direction, the swing fulcrum is located inside the outer edge of the operation button 120 and is configured to overlap with the operation button 120.

[0133] In addition, in one embodiment of the input device 100, the first switch and the second switch are rubber dome switches.

[0134] Therefore, for the input device 100 of one embodiment, the first switch and the second switch, which are both rubber dome switches, can be pressed straight down by actuators 140-1, 140-4 and actuators 140-2, 140-3, thus suppressing the occurrence of the malfunctions characteristic of the rubber dome switches in the first switch and the second switch.

[0135] The present invention has been described in detail above with respect to one embodiment of the invention. However, the present invention is not limited to these embodiments. Various modifications or alterations can be made within the scope of the spirit of the present invention as described in the patent claims.

[0136] This international application claims priority based on Japanese Patent Application No. 2021-122184, filed on July 27, 2021, the entire contents of which are incorporated herein by reference.
