Abstract
In a multidirectional input device having a sliding member that moves by tilting operation of an operation shaft, play between an insertion hole of the sliding member and the operation shaft is eliminated. The operation shaft (4) tilts about a base (4 a) as a fulcrum, and the 2 nd slide member (26) moves laterally in association with the tilting of the operation shaft (4). The restoring force to the neutral position is imparted from the 2 nd slide member (26) to the operation shaft (4) by a restoring cam (26c) of the 2 nd slide member (26). The annular body (29) having elasticity is held by the operation shaft (4). The annular body (29) is brought into pressure contact with the inclined portion (26b) of the 2 nd slide member (26) by the restoring force of the central elastic portion (11). The rattling of the operation shaft (4) in the insertion hole (26a) of the 2 nd slide member (26) is suppressed.

Detailed Description
As shown in fig. 1 and 2, the multidirectional input device 1 has a housing. The housing is composed of a lower housing 2 and an upper housing 3. The lower case 2 and the upper case 3 are both made of synthetic resin. The elastic hook 2a is formed at a plurality of positions on the lower case 2, and the hooking protrusion 3a is formed at a plurality of positions on the upper case 3. The open end of the lower case 2 and the open end of the upper case 3 are combined, and the elastic fastener 2a is hooked on the hooking protrusion 3a, thereby assembling the case.
As shown in fig. 1 and 2, a circular opening 3b is formed in the center of the top plate 3c of the upper case 3, and an operation shaft 4 provided inside the case protrudes upward from the opening 3 b. The opening 3b is a circular hole, and the inner diameter thereof is formed larger than the diameter of the operation shaft 4. The operation shaft 4 is made of metal, and as shown in fig. 4, a base portion 4a of the operation shaft 4 is located in a position close to the bottom portion 2b of the lower case 2. The upper portion of the operation shaft 4 protruding from the opening 3b is an operated portion 4 b. An operation knob is fitted to the operated portion 4 b.
As shown in fig. 4, a stationary base 5 is provided below the inside of the lower case 2. The stationary base 5 is made of synthetic resin. As shown in fig. 2, a plurality of downward fixing projections 5a are integrally formed on the fixing base 5. As shown in fig. 4, fixing holes 2c are formed at a plurality of positions in the bottom portion 2b of the lower case 2, the fixing projections 5a are inserted into the fixing holes 2c, and the front ends (lower end portions in the figure) of the fixing projections 5a are deformed by a heat caulking process or the like, whereby the fixing base 5 is fixed to the lower case 2.
As shown in fig. 2, a disk-shaped flange 7 is integrally formed on the stationary base 5, and a film 10 is sandwiched between and fixed to the bottom 2b of the lower case 2 and the flange 7. The membrane 10 is formed of a non-conductive synthetic rubber material. As shown in fig. 2, a central elastic portion 11 is integrally formed in the film 10, and a peripheral elastic portion 12 is integrally formed around the central elastic portion 11 at 8. The central elastic portion 11 protrudes upward, and functions as a return biasing member that returns the operation shaft 4 upward when the operation shaft 4 is pushed in. The peripheral elastic portion 12 at the point 8 also exerts an elastic force to return to the protruding shape when pushed into the bottom portion 2b of the lower case 2.
As shown in fig. 2 and 4, an insulating substrate 13 is provided and fixed to the bottom 2b of the lower case 2. A central contact portion 14 and a peripheral contact portion 15 surrounding the central contact portion 14 at 8 are provided on the upper surface of the insulating substrate 13.
The center contact portion 14 has a pair of conductive portions. A conductive body is integrally provided on the lower surface of the central elastic portion 11 of the film 10, and the press-in detection portion is constituted by a pair of conductive portions of the central contact portion 14 and the conductive body on the lower surface of the central elastic portion 11. In the press-fit detection portion, the electrical conduction state between the pair of conductive portions of the central contact portion 14 is detected by switching between contact with and separation from the conductive body on the lower surface of the central elastic portion 11. The peripheral contact portions 15 at 8 each also have a pair of conductive portions. A conductor is integrally provided on the lower surface of the peripheral elastic portion 12 of the film 10, and the distortion detection portion at 8 is constituted by a pair of conductive portions of the peripheral contact portion 15 and the conductor on the lower surface of the peripheral elastic portion 12. In the skew detection unit, the state of electrical conduction between the pair of conductive portions of the peripheral contact portion 15 is detected by switching between contact with and separation from the conductive body on the lower surface of the peripheral elastic portion 12.
As shown in fig. 2, a shaft support member 6 is integrally formed on the stationary base 5 so as to extend upward from the center. As shown in fig. 4, the central elastic portion 11 enters the space inside the shaft support member 6. The shaft support member 6 is formed with a support hole 6a penetrating vertically and a tapered surface 6b continuous with an upper opening end of the support hole 6 a. The tapered surface 6b is formed to gradually increase in diameter upward. The diameter of the base portion 4a of the operation shaft 4 is sized to be inserted into the support hole 6a, and the base portion 4a is inserted into the support hole 6 a. The support hole 6a functions as a thrust receiving portion that slidably supports the operation shaft 4 in a direction along the shaft core O.
As shown in fig. 4, a pressing pad 8 is interposed between the base portion 4a of the operation shaft 4 and the central elastic portion 11 of the film 10. The pressing pad 8 is made of synthetic resin and formed in a disc shape. When the operation shaft 4 is pushed along the shaft core O, the central elastic portion 11 is pushed in through the pressing spacer 8. Since the inner diameter of the support hole 6a formed in the shaft support member 6 is formed slightly larger than the diameter of the base portion 4a of the operation shaft 4, the contact portion between the base portion 4a of the operation shaft 4 and the pressing pad 8 serves as a skew support portion, and the operation shaft 4 can perform a skew operation with the skew support portion as a fulcrum.
As shown in fig. 2, a detection hole 7a is opened at 8 in the flange portion 7 of the stationary base 5. As shown in fig. 4, the peripheral elastic portions 12 at 8 formed by the film 10 enter the inside of the detection holes 7a, respectively.
As shown in fig. 2 and 4, the guide member 20 is housed inside the upper case 3, and the 1 st slide member 25 and the 2 nd slide member 26 are movably interposed between the top plate portion 3c of the upper case 3 and the guide member 20. The guide member 20 is formed of a synthetic resin material. Elastic clips 22 are integrally formed at a plurality of positions on the outer peripheral portion of the guide member 20. The elastic clip 22 is formed in a cantilever shape with a lower side integrated with the guide member 20, and a projection projecting outward of the guide member 20 is provided at an upper end portion. In the upper case 3, the 1 st slide member 25 and the 2 nd slide member 26 are housed from the lower side, and when the guide member 20 is fitted into the upper case 3 from the lower side, as shown in fig. 4, the elastic clip 22 inserted while being flexed is hooked on a part of the upper case 3, and the guide member 20 is positioned and fixed in the upper case 3.
As shown in fig. 3, a slide projection 25a extending in the Y direction is integrally formed on the lower surface of the 1 st slide member 25. As shown in fig. 2, a guide groove 23 extending in the Y direction is formed in the upper portion of the guide member 20, and the slide projection 25a is guided slidably in the Y direction in the guide groove 23. As shown in fig. 3, a guide recess 25b extending in the X direction is formed in a lower portion of the 1 st slide member 25, and the 2 nd slide member 26 is held in the guide recess 25b so as to be movable in the X direction. The 1 st slide member 25 and the 2 nd slide member 26 are formed of a synthetic resin material.
The slide assembly in which the 2 nd slide member 26 is inserted into the guide recess 25b of the 1 st slide member 25 is held and housed between the top plate portion 3c of the upper case 3 and the guide member 20 in a state in which the slide projection 25a is inserted into the guide groove 23. The 1 st slide member 25 is movable in the Y direction with respect to the guide member 20, and the 2 nd slide member 26 is movable in the X direction with respect to the 1 st slide member 25. Thereby, the 2 nd sliding member 26 is movable in both the X direction and the Y direction.
As shown in fig. 3 and 9, an insertion hole 26a penetrating vertically and an inclined portion 26b continuing to the lower side of the insertion hole 26a are formed in the center portion of the 2 nd slide member 26. The insertion hole 26a is a cylindrical hole whose inner diameter dimension becomes larger than the diameter of the operation shaft 4. The inclined portion 26b continues from the opening end of the lower side of the insertion hole 26 a. The inclined portion 26b is a tapered surface whose opening gradually increases toward the bottom portion 2b of the lower housing 2 and the shaft support member 6. As shown in fig. 3, the 1 st slide member 25 is formed with an elongated hole 25c that opens toward the movement region in the X direction of the insertion hole 26 a.
As shown in fig. 4, 5, and the like, a holding groove 4c is formed in the operating shaft 4 between the base portion 4a and the operated portion 4 b. The cross-sectional shape of the holding groove 4c has a plurality of corners, and is approximately trapezoidal. The annular body 29 is fitted into and held by the holding groove 4 c. The annular body 29 is made of a material having elasticity and elasticity such as a synthetic rubber material, and has an inner diameter smaller than the diameter of the bottom of the holding groove 4c when no external force is applied. The ring body 29 is inserted with the operation shaft 4 inside in a forcibly expanded state, and is fitted into the holding groove 4c of the operation shaft 4. The annular body 29 fitted in the holding groove 4c has an inner diameter reduced to the same size as the diameter of the bottom of the holding groove 4c, and is held so as not to easily come out of the holding groove 4 c. The annular body 29 serves as an abutment member that is continuous in the circumferential direction on the outer circumferential surface of the holding shaft 4. The abutment member does not necessarily have to have an annular shape, and may be formed such that, for example, elastic bodies are intermittently arranged in the circumferential direction and the respective elastic bodies are embedded in the operation shaft 4.
As shown in fig. 4 and 5, the operated portion 4b of the operating shaft 4 holding the annular body (contact member) 29 faces upward, and is inserted into the insertion hole 26a of the 2 nd slide member 26 and the elongated hole 25c of the 1 st slide member 25 from below, and further into the opening 3b formed in the top plate portion 3c of the upper case 3. When the lower case 2 and the upper case 3 are combined, the restoring elastic force of the central elastic portion (restoring urging member) 11 formed in the central portion of the film 10 acts on the base portion 4a of the operation shaft 4 via the press pad 8, and urges the operation shaft 4 upward as a restoring direction. As shown in fig. 4 and 5, the annular body (abutment member) 29 is in pressure contact with the inclined portion 26b formed on the 2 nd slide member 26 by the restoring force.
The inner diameter of the insertion hole 26a is larger than the diameter of the operation shaft 4 so that the operation shaft 4 can tilt inside the insertion hole 26a of the 2 nd sliding member 26. However, as shown in fig. 4 and 5, when the operation shaft 4 is in the neutral posture, the annular body 29 is in pressure contact with the inclined portion 26b, and therefore, the operation shaft 4 in the neutral posture does not rattle inside the insertion hole 26 a.
The annular body 29 is made of a stretchable material, and when the operation shaft 4 is tilted as shown in fig. 7, a part (i) of the annular body 29 located on the tilted side is deformed by being pressed between the operation shaft 4 and the tilted portion 26 b. Therefore, the operation shaft 4 can be tilted inside the insertion hole 26 a. Further, as shown in fig. 8 and 9, when the operation shaft 4 is press-fitted, the annular body 29 held by the operation shaft 4 is separated downward from the inclined portion 26b, and the press-fitting operation of the operation shaft 4 by the annular body 29 does not act as a load.
As shown in fig. 3, return cams 26c are formed on both sides in the X direction on the lower surface of the 2 nd slide member 26 across the insertion hole 26 a. As shown in the cross-sectional view of fig. 7, the return cam 26c is a concave cam, and is formed so that the center portion is deepest and gradually becomes shallower toward both sides in the X direction and both sides in the Y direction. The return cam 26c is formed such that, when viewed from below, a groove portion extending in the X direction and a groove portion extending in the Y direction intersect each other, and the depth of the intersecting portion is larger than the depth of the other portions, and gradually becomes smaller toward both ends of the groove portion.
As shown in fig. 2, in the guide member 20, housing recesses 24 are formed on both sides in the X direction with respect to the center hole 21, and a return pin 27 and a return spring 28 that biases the return pin 27 are housed in each housing recess 24. The restoring pin 27 is a metal pin, and the restoring spring 28 is a compression coil spring. The sliding head 27a of the return pin 27 is urged to the return cam 26c by the urging force of the return spring 28. When the operation shaft 4 is tilted in the X direction or the Y direction and the 2 nd sliding member 26 is moved in the X direction or the Y direction, the return cam 26c slides the sliding head 27a of the return pin 27. The depth of the return cam 26c gradually becomes shallower toward both ends of the groove, and therefore, a return operation force for always returning the 2 nd sliding member 26 to the neutral posture acts.
As shown in fig. 2 and 4, a skew operating member 31 is provided in the housing. The skew operating member 31 is made of synthetic resin, and has a slide hole 31a penetrating vertically at the center. At least a part of the slide hole 31a has a quadrangular cross section. A part of the operation shaft 4 is also rectangular in cross section, and the rectangular part of the operation shaft 4 is inserted into the rectangular part of the slide hole 31 a. Therefore, the operation shaft 4 is slidable in the axial direction inside the slide hole 31a, but the operation shaft 4 and the skew operation member 31 are restricted from each other in the rotational direction of the operation shaft 4, and the operation shaft 4 and the skew operation member 31 rotate together.
The upper portion of the skew actuating member 31 is located inside the center hole 21 of the guide member 20. A spherical sliding surface 31b is formed in the middle belly portion of the skew operating member 31. As shown in fig. 4, a concave spherical guide surface 20a is formed on the lower inner surface of the guide member 20, and the skew operation member 31 is slidable along the guide surface 20a via a sliding surface 31b, so that the skew operation member 31 can perform a skew operation together with the operation shaft 4. The sliding surface 31b of the skew operating member 31 and the guide surface 20a of the guide member 20 constitute a skew guide mechanism for guiding the skew operation of the operating shaft 4.
As shown in fig. 2, a flange portion 31c is integrally formed at a lower portion of the skew actuating member 31. As shown in fig. 4, the actuator 32 is sandwiched between the flange portion 31c and the stationary base 5. The actuator 32 has a disk shape, and a pressing protrusion 32a is integrally formed at 8 of the lower surface. Each pressing projection 32a faces a detection hole 7a formed in the flange portion 7 of the stationary base 5, and the peripheral elastic portion 12 of the membrane 10 that has entered the detection hole 7a abuts against the pressing projection 32 a.
As shown in fig. 2 and 4, a rotary member 33 is provided around the flange portion 31c of the skew actuating member 31. Coupling protrusions 31d extending in the X and Y directions are formed on the flange portion 31c, and coupling recesses 33a corresponding to the coupling protrusions 31d are formed on the rotary member 33. The coupling protrusions 31d enter the coupling recesses 33a, and when the operation shaft 4 and the skew moving member 31 rotate, the rotation member 33 can also rotate together. However, since the coupling protrusion 31d can move up and down in the coupling recess 33a, the rotary member 33 does not tilt when the operation shaft 4 and the skew operation member 31 perform a skew operation.
As shown in fig. 2, concave-convex portions 33b are formed on the upper surface of the rotary member 33 at a constant pitch in the circumferential direction, and a pressing projection 34a of a plate spring 34 fixed to the lower end of the guide member 20 is pressed against the concave-convex portions 33 b. As a result, when the operation shaft 4 is rotated and the rotating member 33 is rotated together, a rotation click feeling can be generated.
At the lower portion of the rotary member 33, detection pieces 33c arranged at a certain pitch in the circumferential direction are integrally formed. An optical detection unit (not shown) is provided as a rotation detection unit on the insulating substrate 13 in the lower case 2, and constitutes the rotation detection unit. When the rotary member 33 rotates together with the operation shaft 4, the detection pieces 33c are sequentially detected by the optical detection unit, and thereby the rotational operation of the operation shaft 4 can be detected.
Next, the operation of the multidirectional input device 1 will be described.
In fig. 4 and 5, the operation shaft 4 is in a neutral posture. When no external force acts on the operated portion 4b of the operating shaft 4, the slide head portion 27a of the return pin 27 comes into pressure contact with the central portion of the return cam 26c formed in the 2 nd slide member 26, and the insertion hole 26a of the 2 nd slide member 26 returns to the neutral position in the X direction and the X direction.
At this time, the operating shaft 4 is biased upward by the biasing force of the central elastic portion (return biasing member) 11 of the film 10, and therefore, the annular body (abutment member) 29 held by the operating shaft 4 is in pressure contact with the inclined portion 26b of the 2 nd sliding member 26. As shown in fig. 5, the inner diameter of the insertion hole 26a of the 2 nd slide member 26 is larger than the outer diameter of the operation shaft 4, but the inclined portion 26b and the insertion hole 26a form a concentric circle, and therefore, the operation shaft 4 is positioned to the center of the insertion hole 26a by the pressure contact of the annular body 29 and the inclined portion 26 b. Therefore, the operating shaft 4 can be prevented from wobbling in the insertion hole 26a, and the operating shaft 4 is positioned such that the shaft center O is perpendicular to the bottom portion 2b of the lower case 2 and is positioned at the center of the opening 3b formed in the top plate portion 3c of the upper case 3.
Fig. 6 and 7 show the skew action of the operation shaft 4.
In fig. 6 and 7, an operation force is applied to the operated portion 4b of the operation shaft 4, and the shaft center O of the operation shaft 4 is distorted in one side in the X direction. The operation shaft 4 can also perform a skew operation in the Y direction.
As shown in fig. 6 and 7, when the operation shaft 4 is skewed, a tilting force Fx in the X direction is applied to the 2 nd sliding member 26 from the stretchable annular body (abutting member) 29 held by the operation shaft 4, and the 2 nd sliding member 26 moves in the X direction. Since the inner diameter of the insertion hole 26a formed in the 2 nd slide member 26 is larger than the diameter of the operation shaft 4, the operation shaft 4 can be tilted inside the insertion hole 26a, and at this time, the annular body 29 can be freely expanded and contracted.
When the operation shaft 4 performs the skew operation, the skew operation members 31 fitted to the outer periphery of the operation shaft 4 are tilted together. The actuator 32 located on the lower side of the skew actuating member 31 is tilted by the skew action of the skew actuating member 31, and the peripheral elastic portion 12 of the film 10 is pressed by 1 or 2 of the pressing protrusions 32a provided on the lower surface 8 of the actuator 32 in the skew direction. The conductor provided on the lower surface of the pressed peripheral elastic portion 12 is in contact with the pair of conductive portions of the peripheral contact portion 15, the conductive portions are electrically connected to each other, and the tilt detection portion operates to detect the tilt of the operation shaft 4.
As shown in fig. 6, when the 2 nd slide member 26 moves in the X direction by the tilting operation of the operation shaft 4, the slide head portion 27a of the return pin 27 is displaced in the X direction from the central portion of the return cam 26c formed in the 2 nd slide member 26, and therefore, a pressing force is applied from the slide head portion 27a to the return cam 26c by the return spring 28, and a return force to return to the neutral posture shown in fig. 4 and 5 acts on the 2 nd slide member 26. Therefore, when the force for performing the tilting operation is stopped, the operation shaft 4 is returned to the neutral posture shown in fig. 4 and 5.
Fig. 8 and 9 show the pushing operation of the operation shaft 4.
When the operation shaft 4 is pressed, the operation shaft 4 slides downward in the slide hole 31a formed in the skew actuating member 31, and the pressing pad 8 is pressed downward by the base portion 4a of the operation shaft 4. The pressing pad 8 presses the central elastic portion 11 of the film 10, and the conductive body provided on the lower surface of the central elastic portion 11 comes into contact with the pair of conductive portions of the central contact portion 14 shown in fig. 2, thereby operating the press-in detection portion.
At this time, as shown in fig. 8 and 9, the ring body 29 held by the operating shaft 4 is separated from the inclined portion 26b formed in the 2 nd sliding member 26. Thus, the presence of the annular body 29 does not become a load for the press-fitting operation of the operation shaft 4.
Subsequently, when the operation shaft 4 is rotated, the skew operation member 31 is rotated together with the operation shaft 4, and further, the rotation member 33 is rotated together, and the rotation detection unit is operated. At this time, the annular body 29 held by the operating shaft 4 slides on the inclined portion 26b of the 2 nd sliding member 26. Since the annular body 29 has a circular cross section, the frictional resistance between the annular body 29 and the inclined portion 26b is also extremely small. This also allows the operation shaft 4 to rotate smoothly.
