Description

  The present invention relates to a manual operation device in which a bearing member mounted on a base slidably holds a shaft portion of a drive body so that the drive body rotates when an operating force is applied. In particular, the present invention relates to a bearing mounting structure for mounting a shaft portion of a driving body and its bearing member to a base.

  As a manual operation device that applies an operating force to a drive body that is pivotally supported by a base (frame) and rotates and moves the drive body, for example, when the drive body is swung via an operation lever, the swinging movement is performed. There is an input device that can detect an electric signal according to a direction and a swing amount. In this type of manual operation device, if the structure is such that the shaft portion of the drive body is inserted into the through hole of the base and is pivotally supported, complicated assembly work is unavoidable.

Therefore, conventionally, a pair of notch portions that are open in the same direction are provided on the base, and a manual operation device that can support the shaft by inserting the shaft portion of the drive body into both the notch portions from the opening end side. Has been proposed (see, for example, Patent Document 1). In this conventional example, a pair of notch portions for mounting a pair of bearing members attached to the shaft portion of the driving body is provided at a position facing the upper end portion of the base at a predetermined interval, Each notch is open upward. The notch is formed as a groove having a substantially constant width so that the corresponding bearing member can be inserted from above. The bearing member is formed with a shaft hole into which the shaft portion of the drive body is slidably fitted, and a part of the bearing member is substantially matched with the shape of the corresponding notch portion. Therefore, after assembling, the bearing members are attached to the shafts at both ends of the drive body, and then each bearing member is pushed into the corresponding notch from above the base so that the drive body is pivotally supported on the base. Thus, the assembly workability can be greatly improved.
JP 2005-332038 A (page 4-6, FIG. 3)

  In the above-described conventional example, the bearing member attached to the shaft portion of the drive body is simply pushed into the notch portion of the base and attached, so that the drive body is pivotally supported by the base, so that the assembly work can be performed smoothly. In this state, the bearing member may still fall off from the notch portion of the base. Therefore, it is necessary to take another measure for preventing the bearing member from coming off. That is, since the position of the bearing member mounted on the notch portion of the base is not restricted by an external force that is opposite to the mounting direction, the cover member or the like is brought into contact with the bearing member. If measures for stopping are not taken, there is a possibility that the bearing member and the driving body may come off the base during use of the manual operation device. Therefore, when adopting such a conventional bearing mounting structure, a separate member having a special shape capable of preventing the bearing member from falling off must be accurately aligned with the bearing member and assembled. There has been a problem that the assembly workability is deteriorated and the parts cost is increased. Further, in the case of a semi-finished product before such another member is assembled, since the bearing member is not in a state of retaining, the bearing member and the driving body may be detached from the base during the assembly. There was room for improvement in terms of handling in a semi-finished product.

  The present invention has been made in view of the actual situation of the prior art as described above. The purpose of the present invention is to provide a manual operation device that can easily attach the shaft portion of the driving body and its bearing member to the base and does not fall off. The object is to provide a bearing mounting structure.

  In order to achieve the above object, according to the present invention, a notch is provided at a position facing each other with a predetermined interval, and each notch is opened in the same direction, and these notches A pair of bearing members mounted on the shaft, and a drive body having a shaft portion slidably held by the bearing members and pivotally supported by the base, and the shaft Part can be inserted into the notch from the opening end of the notch, and in the manual operation device for rotating the drive body by applying an operating force, at least one of the bearing members corresponds A holding portion that is externally fitted to the shaft portion, an inner engagement portion that protrudes outward from the holding portion along the inner side surface of the base, and an outer engagement surface that extends from the holding portion along the outer side surface of the base. And an outer engagement portion that protrudes in the direction, and the bearing member is mounted The notch has a bearing mounting structure in which a fitting hole into which the holding part is inserted and a communication passage extending from the fitting hole to the opening end and an inlet groove narrower than the holding part. .

  According to such a bearing mounting structure, the holding portion of the bearing member is removed from the outside in the axial direction with respect to the shaft portion of the driving body inserted into the fitting hole from the opening end side of the notch portion through the inlet groove. The holding portion can be fitted into the fitting hole, and when the holding portion wider than the inlet groove is inserted into the fitting hole, the bearing member is moved toward the opening end side of the notch portion. It becomes a regulated state. In this state, the inner engagement portion of the bearing member can be opposed to the inner surface of the base, and the outer engagement portion of the bearing member can be opposed to the outer surface of the base. The movement can be regulated. Therefore, the bearing member can be mounted in the notch portion of the base without fear of dropping off, and there is no possibility that the shaft portion of the driving body fitted into the bearing member will drop off from the base.

  If any one of the bearing members is mounted on the base as described above, the other bearing member is unlikely to fall out of the base even if no retaining measures are taken. In order to reliably prevent the dropout, the other bearing member is preferably mounted on the base as described above.

  In the above configuration, the inner engagement portion of the bearing member is formed to be narrower than the inlet groove of the notch portion, and the holding portion of the bearing member is rotatably fitted into the fitting hole of the notch portion. If the inner engagement portion is aligned with the inlet groove and passed through the inlet groove, the holding portion is fitted into the fitting hole, and then the bearing member is appropriately rotated to set the inner engagement portion as a base. By facing the inner side surface of the table, the bearing member can be in a state in which movement in the axial direction is restricted. In this case, if at least a part of the outer engaging portion is provided as a rotating lever portion, the bearing member can be easily rotated by engaging a finger with the rotating lever portion. Furthermore, if a stopper portion that can lock the rotation lever portion at a predetermined rotation position is provided at a position overlapping the rotation lever portion on the outer side surface of the base, the positional deviation of the bearing member mounted on the notch portion is prevented. It can be surely prevented.

  Further, in the above configuration, the inner engagement portion of the bearing member has a tapered flange portion that can pass through the fitting hole by being press-fitted into the fitting hole of the notch portion from the outside in the axial direction, and the bearing member When the holding portion is inserted into the fitting hole so as not to rotate, it is possible to attach the bearing member to the notch portion simply by pushing the bearing member from the outside in the axial direction.

  In the bearing mounting structure for a manual operation device according to the present invention, the bearing member has a holding portion, an inner engagement portion, and an outer engagement portion, and the notch portion of the base has a fitting hole and an inlet groove, The bearing member is attached to this notch, and the holding portion of the bearing member is removed from the outside in the axial direction with respect to the shaft portion of the driving body inserted into the fitting hole of the notch from the opening end side. By fitting the holding portion into the fitting hole, the bearing member can be easily attached to the notch portion of the base without fear of dropping off. Therefore, the shaft portion of the driving body and its bearing member can be easily mounted on the base, and there is no risk of dropping during assembly or during use, and a bearing mounting structure excellent in assembly workability and reliability can be realized at low cost.

  The manual operation device shown in these drawings is a main body portion of a force sense imparting input device in which an electrically controlled force sense is imparted to an operation lever. As is well known, the haptic input device consolidates the function adjustments of in-vehicle control devices such as air conditioners, audio, navigation, etc., into a single operating lever. With the force feedback function, the operation amount of the operation lever is given an external force such as resistance and thrust according to the operation direction, so that the operation feeling is good and the desired operation can be performed reliably. It is an input device.

  The manual operation device according to the present embodiment is housed in a housing (not shown) having a through hole on the upper surface, is installed in a car center console or the like, and swings the operation lever 1 protruding upward from the through hole. The input operation can be performed by moving it. This manual operation device includes a base (frame) 3 erected on the circuit board 2, and first and second shafts that are pivotally supported by the base 3 so as to be orthogonal to each other. Drive levers 4, 5, first and second rotary motors 6, 7 mounted on the circuit board 2 and having the rotation axes 6 a, 7 a orthogonal to each other, and a rotary encoder mounted on the circuit board 2 8, 9 and photointerrupters 10, 11 and a control unit (not shown) are schematically configured. The operation lever 1 can be swung in an arbitrary direction, and the drive levers 4 and 5 are swung (rotated) by an operating force applied via the operation lever 1.

  The base 3 is obtained by integrating a first support plate 31 and a second support plate 32 via a connecting plate 33 and a spacer 34. The first support plate 31 is an L-shaped metal plate in plan view, and the second support plate 32 is a W-shaped metal plate in plan view. These two support plates 31 and 32 are arranged so as to face each other and are firmly connected by caulking and fixing the connection plates 33 at both ends. As shown in FIG. In this, a wide space S1 having a square shape in plan view and two narrow spaces S2 having substantially the same width as the connecting plate 33 are defined. In each narrow space S2, a spacer 34 is inserted in the vicinity of the wide space S1, and a screw member 35 is fastened so that the spacer 34 is clamped between the support plates 31 and 32. Therefore, the wide space S1 and the narrow space S2 are each set to a predetermined width dimension. Further, the upper end portions of the support plates 31 and 32 are provided around the wide space S1 and are opened upward to face each other, and are opposed to each other. 39, and the first straight line connecting the notches 36 and 38 and the second straight line connecting the notches 37 and 39 are set to be orthogonal to each other in the upper part of the wide space S1. Yes. Since the pair of shaft portions 41 and 42 and the bearing members 43 and 44 of the first drive lever 4 are mounted in the notches 36 and 38, the rotation axis of the drive lever 4 matches the first straight line. To do. In addition, since the pair of shaft portions 51 and 52 and the bearing members 53 and 54 of the second drive lever 5 are attached to the notches 37 and 39, the rotation axis of the drive lever 5 is the second straight line. Matches.

  The drive levers 4 and 5 are pivotally supported on the base 3 in such a manner that their rotation axes are orthogonal to each other as described above. An operating lever 1 is slidably inserted in a crossing portion of a long hole 4a of the first drive lever 4 and a long hole (not shown) of the second drive lever 5, and the longitudinal direction of the control lever 1 is The central portion and the upper portion of the second drive lever 5 are rotatably connected using a pin 12. When the first drive lever 4 is attached to the base 3, the shaft portions 41 and 42 are inserted into the cutout portions 36 and 38 from above the wide space S1, and then the shaft portions 41 and 42 are axially outward. Then, the bearing members 43 and 44 are externally fitted, and the bearing members 43 and 44 are attached to the notches 36 and 38. Thereafter, the second drive lever 5 connected to the operation lever 1 is attached to the base 3 in the same procedure (see FIG. 5). That is, after the shaft portions 51 and 52 are inserted into the cutout portions 37 and 39 from above the wide space S1, the bearing members 53 and 54 are externally fitted to the shaft portions 51 and 52 from the outside in the axial direction. The members 53 and 54 are attached to the notches 37 and 39.

  A gear portion 45 having a tooth portion 45 a at the tip is integrally formed on one side portion of the first drive lever 4, and a detection plate 46 is fixed to the other side portion of the first drive lever 4. In this manual operation device, the tooth portion 45 a of the first drive lever 4 is engaged with a gear 61 fixed to the rotary shaft 6 a of the first rotary motor 6. The detection plate 46 passes through the recess 10a of the photo interrupter 10 as the first drive lever 4 swings. Similarly, a gear portion 55 having a tooth portion 55a at the tip is integrally formed on one side portion of the second drive lever 5, and a detection plate 56 is fixed to the other side portion of the second drive lever 5. ing. The tooth portion 55a of the second drive lever 5 meshes with a gear 71 fixed to the rotary shaft 7a of the second rotary motor 7, and the detection plate 56 of the photo interrupter 11 is moved along with the swing of the drive lever 5. It passes through the recess 11a.

  The rotary motors 6 and 7 are mounted on the circuit board 2 in an arrangement in which the rotary shafts 6a and 7a are orthogonal to each other. The rotary shaft 6 a of the first rotary motor 6 is connected to the central portion of the code plate 81 of the rotary encoder 8 and rotates integrally with the code plate 81. Further, when an operating force for swinging the first drive lever 4 is applied, the rotary shaft 6 a is rotationally driven via the tooth portion 45 a and the gear 61. Similarly, the rotary shaft 7a of the second rotary motor 7 is connected to the central portion of the code plate 91 of the rotary encoder 9, and rotates integrally with the code plate 91 and swings the second drive lever 5. When the operating force to be moved is applied, the rotating shaft 7a is rotationally driven via the tooth portion 55a and the gear 71.

  The rotary encoder 8 is configured by the above-described code plate 81 and a photo interrupter 82 mounted on the circuit board 2, and a part of the code plate 81 is disposed in the recess 82 a of the photo interrupter 82. The photo interrupter 82 includes an LED (light emitting element) (not shown) and a phototransistor (light receiving element) which are opposed to each other via a recess 82a, and can detect rotation information of the code plate 81. Similarly, the rotary encoder 9 is configured by the above-described code plate 91 and a photo interrupter 92 mounted on the circuit board 2, and a part of the code plate 91 is disposed in the recess 92 a of the photo interrupter 92. Therefore, the rotation information of the code plate 91 can be detected by the photo interrupter 92.

  The photo interrupter 10 is provided with an LED and a phototransistor (not shown) that are opposed to each other through a recess 10a. The photo interrupter 10 outputs an ON signal when the detection plate 46 of the first drive lever 4 is out of the recess 10 a, but the detection plate 46 is recessed as the first drive lever 4 swings. If the light enters the LED 10a, the LED light is shielded and an off signal is output. Similarly, the photo interrupter 11 outputs an ON signal when the detection plate 56 of the second drive lever 5 is in a position away from the recess 11a, and outputs an OFF signal when the detection plate 56 enters the recess 11a. . Signals output from the photo interrupters 10 and 11 are taken into a control unit (not shown) so that the reference positions of the drive levers 4 and 5 are calculated. Furthermore, the signals detected by the photo interrupters 82 and 92 of the rotary encoders 8 and 9 are taken into this control unit, and the rotational movement direction (swinging direction) and the rotation amount (from the reference position of the drive levers 4 and 5) (Swing angle) is calculated.

  The control unit outputs a control signal determined based on data or a program stored in the memory to the rotary motors 6 and 7. This control signal is a signal corresponding to the operation feeling given to the operation lever 1, and the type of the signal includes generation of vibration, change of operating force (resistance force or thrust force), and the like. The circuit components of the control unit are mounted on the bottom surface of the circuit board 2 or another circuit board (not shown).

  Next, a structure for attaching the spacer 34 to the first and second support plates 31 and 32 will be described in detail mainly with reference to FIG. As described above, the support plates 31 and 32 are firmly connected by the connection plate 33. However, the spacer 34 is indispensable for accurately defining the distance between the support plates 31 and 32 in the wide space S1. is there. The spacer 34 is formed in a quadrangular prism shape having a through hole 34 a, and both support plates 31, 32 facing each other through the narrow space S <b> 2 clamp the spacer 34 by fastening the screw member 35. The spacer 34 is provided with a pair of upper and lower engaging protrusions 34 b and 34 c on the end face on the side pressed against the first support plate 31. The first support plate 31 is provided with an opening 31a through which the screw member 35 is inserted and a notch groove 31d into which the engaging protrusions 34b and 34c are inserted at the attachment position of the spacer 34. The cut groove 31d includes an introduction groove portion 31b that forms a communication path extending from the upper edge of the first support plate 31 to the opening 31a, and a concave groove portion 31c that communicates with the opening 31a on an extension line of the introduction groove portion 31b. 34 is attached to the first support plate 31 with the upper engaging protrusion 34b engaged with the introducing groove 31b and the lower engaging protrusion 34c engaged with the recessed groove 31c. The second support plate 32 is provided with an opening 32 a that functions as a screw hole into which the screw member 35 is screwed, at a position facing the opening 31 a of the first support plate 31. That is, a female screw groove (not shown) that is screwed with the screw member 35 is formed on the inner peripheral wall of the opening 32a.

  When attaching the spacer 34 to both the support plates 31, 32, first, the lower engaging protrusion 34 c of the spacer 34 is aligned with the introduction groove portion 31 b of the first support plate 31, and both the support plates 31, 32 are positioned. The spacer 34 is inserted between them. As a result, the engaging projection 34c passes through the introduction groove 31b and the opening 31a and is fitted into the concave groove 31c, and the upper engagement projection 34b is fitted into the introduction groove 31b, so that the spacer 34 is temporarily placed at a predetermined position. It becomes a fixed state. Thereafter, the screw member 35 is inserted into the through hole 34a from the opening 31a side and screwed into the opening 32a in a fastened state, thereby fixing the spacer 34 between the support plates 31 and 32 as shown in FIG. Therefore, the facing distance between the two support plates 31 and 32 is defined with high accuracy.

  Next, a structure for pivotally supporting the drive levers 4 and 5 on the base 3 (both support plates 31 and 32) will be described. However, a mounting structure for mounting the shaft portions 41 and 42 of the first drive lever 4 and the bearing members 43 and 44 to the notches 36 and 38 of the base 3, and the shaft portions 51 and 52 of the second drive lever 5. There is no fundamental difference between the mounting structure for mounting 52 and its bearing members 53, 54 to the notches 37, 39 of the base 3, so the latter mounting structure will be mainly described with reference to FIGS. Only the details will be described.

  One bearing member 53 for the second drive lever 5 includes a holding portion 53a that has a shaft hole 53b and is fitted on the shaft portion 51, and extends from the holding portion 53a to the inner surface of the first support plate 31. A resin molded product including a pair of inner engaging portions 53c protruding outward and a plurality of outer engaging portions 53d protruding outward along the outer surface of the first support plate 31 from the holding portion 53a. A part of the engaging portion 53d is a rotating lever portion 53e having a shape that allows fingers to be easily hooked. The notch portion 37 of the first support plate 31 to which the bearing member 53 is attached includes a fitting hole 37a for rotatably fitting the holding portion 53a, and an inlet groove that is a communication path from the fitting hole 37a to the opening end. 37b and a concave relief groove 37c communicating with the lower end of the fitting hole 37a. The inlet groove 37b and the relief groove 37c are narrower than the holding portion 53a and wider than the inner engagement portion 53c. . The first support plate 31 is provided with a stopper hole 31e below the cutout portion 37 in which a protrusion 53f (see FIG. 8) protruding from the back surface of the rotary lever portion 53e can be locked.

  When assembling the shaft portion 51 of the second drive lever 5 and its bearing member 53 to the notch portion 37, first, as shown in FIGS. 5 and 6, the shaft portion 51 is moved from the opening end side of the notch portion 37. The shaft portion 51 is slidably fitted into the shaft hole 53b by being inserted into the fitting hole 37a via the inlet groove 37b, and in this state, the holding portion 53a is externally fitted to the shaft portion 51 from the outside in the axial direction. At the same time, the holding portion 53a is fitted into the fitting hole 37a. At this time, as shown in FIG. 7, the pair of inner engaging portions 53 c of the bearing member 53 are allowed to pass through in alignment with the inlet groove 37 b and the relief groove 37 c of the notch portion 37. Thus, when the holding portion 53a wider than the inlet groove 37b and the escape groove 37c is fitted into the fitting hole 37a, the bearing member 53 is attached to the notch portion 37 in a state where movement in the vertical direction is restricted. Thereafter, the bearing member 53 is rotated about 90 degrees along the inner side surface and the outer side surface of the first support plate 31, so that the inner engagement portion 53c faces the inlet groove 37b as shown in FIG. The outer engagement portion 53d including the rotation lever portion 53e can be set to face the outer surface of the first support plate 31 without facing the inner surface of the first support plate 31. It is possible to achieve a state in which the movement of the direction is restricted. As a result, the bearing member 53 is attached to the cutout portion 37 of the first support plate 31 without fear of dropping off, so that the shaft portion 51 fitted into the bearing member 53 drops off from the first support plate 31. There is no fear.

  The other bearing member 54 for the second drive lever 5 is a component having the same shape as the bearing member 53, and the notch 39 of the second support plate 32 to which the bearing member 54 is mounted is also the notch. The shape is the same as the portion 37. Therefore, the procedure for assembling the shaft 52 and the bearing member 54 to the notch 39 is exactly the same as the above procedure. As described above, the bearing mounting structure for the first drive lever 4 is exactly the same as the bearing mounting structure for the second drive lever 5, and the description thereof is omitted.

  Next, the operation of the manual operation device configured as described above will be described. First, when the system of the manual operation device is activated (powered on), the control unit takes in the detection signals of the photo interrupters 10 and 11 and outputs a control signal to the rotary motors 6 and 7. Rotates the drive levers 4 and 5 to automatically return the operation lever 1 to the neutral position. In this case, the rotary motors 6 and 7 may drive the drive levers 4 and 5 so that the outputs of the photo interrupters 10 and 11 are switched from off to on, and the operation lever 1 outputs both the photo interrupters 10 and 11 together. The neutral position is reached when switching from off to on.

  When the operator swings the operation lever 1 in an arbitrary direction with the operation lever 1 automatically returned to the neutral position in this way, the first drive lever 4 and the second drive lever 5 are moved according to the swing direction. Oscillates (rotates) around each rotation axis. Since the code plate 81 rotates in conjunction with the swing of the first drive lever 4 and the code plate 91 rotates in conjunction with the swing of the second drive lever 5, the photo of the rotary encoders 8 and 9 The rotation information of the code plates 81 and 91 is detected by the interrupters 82 and 92, and the signals are taken into the control unit.

  This control unit calculates the rotational movement direction (swinging direction) and the rotation amount (swinging angle) of the drive levers 4 and 5 based on the detection signals of the photointerrupters 10 and 11 and the detection signals of the photointerrupters 82 and 92. In addition, a predetermined control signal is output to the rotary motors 6 and 7. For example, when the operating lever 1 is swung by a predetermined amount in a predetermined direction, a rotational driving force based on the control signal is transmitted from the rotary motors 6 and 7 to the driving levers 4 and 5, and these driving levers When an operating force against the swinging operation is applied to the operation lever 1 via 4 and 5, this operating force is recognized as a click feeling by an operator who manually operates the operation lever 1.

  Thus, in the manual operation device according to the present embodiment, the shaft portions 41, 42, 51, 52 of the drive levers 4, 5 and the bearing members 43, 44, 53, 54 correspond to the base 3. A bearing mounting structure that can be easily mounted in the notches 36 to 39 without dropping is employed. As an example, when the shaft portion 51 of the second drive lever 5 and its bearing member 53 are mounted in the notch portion 37, the opening end side of the notch portion 37 enters the fitting hole 37 a via the inlet groove 37 b. The inserted shaft portion 51 is externally fitted with the holding portion 53a of the bearing member 53 from the outside in the axial direction, and the holding portion 53a is fitted into the fitting hole 37a, and then the bearing member 53 is rotated to engage the inside. If the portion 53c and the outer engagement portion 53d are opposed to the inner surface and the outer surface of the first support plate 31, the bearing member 53 is restricted from moving toward the opening end side of the notch portion 37 and moving in the axial direction. For this reason, it will be in the state by which drop-off from the notch part 37 was prevented. At this time, the bearing member 53 can be easily rotated by engaging a finger with the rotation lever portion 53e. Further, if the bearing member 53 is rotated to a position where the protrusion 53f of the rotating lever portion 53e is immersed in the stopper hole 31e, the bearing member 53 is prevented from rotating and can be prevented from being displaced. Therefore, the bearing member 53 thus mounted on the first support plate 31 is not likely to drop out of the notched portion 37 during the subsequent assembly process or use, so that the shaft portion 51 fitted into the bearing member 53 is cut off. There is no possibility of dropping off from the notch 37.

  As described above, since the procedure for mounting the other shaft portion 52 of the second drive lever 5 and the bearing member 54 to the notch portion 39 is completely the same, the second drive lever 5 eventually has each shaft portion. 51 and 52 and the bearing members 53 and 54 can be easily attached to the corresponding notches 37 and 39 without fear of dropping off. Similarly, the shaft portions 41 and 42 of the first drive lever 4 and the bearing members 43 and 44 can be easily attached to the corresponding cutout portions 36 and 38 without fear of dropping off. Therefore, in this embodiment, a bearing mounting structure excellent in assembling workability and reliability is realized at low cost.

  FIG. 9 is an exploded perspective view of a main part for explaining a bearing mounting structure according to another embodiment of the present invention, and parts corresponding to those in FIG. In FIG. 9, the bearing member 53 having a shaft hole 53b into which the shaft portion 51 is slidably fitted has a holding portion 53a formed in a square column shape, and the notch portion 37 into which the holding portion 53a is inserted. The fitting hole 37a is also a corresponding square hole. Further, a tapered flange portion 53g protruding from the holding portion 53a to the radially outer side is formed on the inner engagement portion 53c of the bearing member 53, and a small diameter side (an anti-holding portion 53a side) of the tapered flange portion 53g is formed. Although slightly smaller than the fitting hole 37a, the larger diameter side (the holding portion 53a side) is slightly larger than the fitting hole 37a. Further, the outer engagement portion 53d of the bearing member 53 is opposed to the large diameter side of the tapered flange portion 53g with a predetermined gap, and the peripheral portion of the fitting hole 37a of the first support plate 31 is opposed to this gap. Has come in.
