Description

  The present invention relates to an in-vehicle dial type operating device.

Japanese Patent Laid-Open No. 11-273506 JP 2000-67696 A JP 2001-184969 A

  In a vehicle such as an automobile, an operation unit for operating an electronic device to be mounted, for example, an air conditioner, a car audio system, and a car navigation system is provided in the vehicle. The operation unit is provided with an operation unit for a vehicle occupant to operate as necessary. Among these, dial type operation devices are often used for air volume adjustment operation units, temperature adjustment operation units or outlet selection operation units of air conditioners, volume operation units of car audio systems, and the like (Patent Documents 1 to 3).

  Such a dial type operating device has a structure in which a dial knob (dial operating portion) is supported on a support base so as to be able to rotate and slide. A lubricant such as grease is applied to smooth the rotation operation of the knob.

  However, since the lubricant is pushed away from the rotational sliding surface with time, there is a problem that the feeling of rotational operation of the dial knob deteriorates (becomes smooth) when used for a long time. Also, since the lubricant flows on the rotating sliding surface mainly along the operation direction as the dial knob is rotated, a part of the section is notched without the rotating sliding surface being connected in an annular shape. Particularly in the case of a dial type operating device having a discontinuous structure, there is a problem that the lubricant is easily pushed away from the end of the rotating sliding surface to the notched section, and the operational feeling is deteriorated at a relatively early stage. .

  The subject of this invention is providing the vehicle-mounted dial type operating device which can ensure the smooth rotation operation feeling of a dial knob over a long period of time.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-mentioned problem, the in-vehicle dial type operating device of the present invention is
A dial operation unit capable of rotating around a predetermined rotation axis;
A support base that contacts the dial operation unit from the rear in the rotational axis direction and supports the dial operation unit while allowing the dial operation unit to rotate and slide with the rotation operation;
The support base is formed with a base-side guide portion that protrudes along the rotational operation direction of the dial operation portion,
The dial operating portion includes a groove-shaped dial-side guide portion configured by a pair of convex portions that engage with the base-side guide portion so as to sandwich the base-side guide portion from both sides along the rotational operation direction. Is formed,
When the base-side guide portion and the dial-side guide portion are engaged, the tip end surface of the base-side guide portion and the groove bottom surface of the dial-side guide portion come into contact with each other, and the engagement occurs when the rotation operation is performed. The rotary operation of the dial operation part is guided in such a way that the combined state is maintained,
A lubricant accommodating recess is formed on at least one of the sliding surface that is the tip surface of the base-side guide portion and the contact surface that is the groove bottom surface of the dial-side guide portion,
Either the dial-side guide part or the base-side guide part or both guide parts are formed in a form having a notch section in which a section is notched in the rotational operation direction,
The base-side guide portion is formed to have the notch section in the rotational operation direction, and the dial operation section is set at a plurality of predetermined angle holding positions in the notch section region of the support base. An outer peripheral side structure including an angular position holding mechanism for holding, and a rotation operation angle position detection mechanism for detecting a rotation operation angle position of the dial operation unit is arranged,
On one of the pair of convex portions constituting the dial side guide portion, a plurality of detected bodies detected by the rotational operation angular position detection mechanism are arranged along the operation path,
The other of the pair of convex portions is formed with a position holding portion that fits with the angular position holding mechanism arranged in the notch section region and holds the dial operation portion at the angle holding position. Features.

  According to the configuration of the present invention described above, either or both of the sliding surface of the support base that supports the dial operation unit and the sliding surface (contact surface) of the dial operation unit that slides on the sliding surface, A lubricant accommodating recess is formed in a shape recessed in the rotational axis direction of the dial operation portion, and the lubricant is accommodated and held in the recess. As a result, part of the lubricant is difficult to be washed away to the outside, and even if it is swept away, it can be replenished with the lubricant contained in the lubricant containing recess. The lubricant can be retained on the surface (support surface) for a long time, and the operational feeling is hardly deteriorated.

  The lubricant accommodating recess can be formed along the rotational operation direction. According to this configuration, since the lubricant accommodating recess can be formed continuously or intermittently long along the rotational operation direction of the dial operation portion, the lubricant is accommodated on the sliding surface between the dial operation portion and the support base. A wide concave portion can be secured. Moreover, since the total amount of lubricant to be accommodated increases, the lubricant can be retained for a long period of time.

  In this case, the lubricant accommodating recess can be formed in a continuous groove shape along the rotational operation direction. The lubricant accommodating recess having a groove shape along the rotational operation direction has a high lubricant accommodating capacity because the wall portions on both sides of the groove function as a lubricant outflow prevention wall portion for preventing the lubricant from flowing out, and the lubricant Can be held for a long time. Furthermore, the lubricant accommodating recess having the groove shape can be formed over a wide range on the sliding surface between the dial operation portion and the support base by being continuously formed along the rotational operation direction. Also, the total amount of lubricant contained can be increased. The lubricant accommodating recess having the groove shape can be easily formed by forming a shape that appears in a V shape or a U shape on a cut surface by a plane including the rotation axis.

  On the other hand, the lubricant accommodating recess can be intermittently formed along the rotational operation direction. Also in this case, the lubricant accommodating recess can be formed over a wide range on the sliding surface between the dial operation portion and the support base, and the total amount of lubricant accommodated can be increased. The intermittently formed lubricant accommodating recesses can be formed as a plurality of bottomed holes. The lubricant accommodating recess formed as a bottomed hole has a high lubricant accommodating capacity because the peripheral wall portion surrounding the hole functions as a lubricant outflow prevention wall portion that prevents the lubricant from flowing out. Can be held.

  By the way, the dial operation portion can be formed with a dial side guide portion along the rotational operation direction in the form having the contact surface, and the support base body is a base body that engages with the dial side guide portion. A side guide part can be formed in the form which has the said sliding surface. In the engaged state of these guide portions, when the dial-side guide portion abuts the sliding surface of the base-side guide portion and the dial operation portion is rotated, the engagement state is maintained. In this manner, the rotary operation of the dial operation unit can be guided.

  In addition, the dial operation unit is configured to have a cylindrical cylindrical main body, and an inner structure that is not rotated with respect to the rotation operation of the dial operation unit can be incorporated inside the cylindrical main body. . Accordingly, the function of the dial type operating device can be improved in a manner that effectively uses the space inside the dial operating unit. The internal structure includes a push operation switch mechanism in which the knob is driven to advance and retreat in the direction of the rotation axis, and the design surface provided at the front end of the dial operation unit in the direction of the rotation axis by irradiating light from the rear in the direction of the rotation axis. At least one of a design surface light emitting display mechanism for lighting and displaying a surface and a pointer position driving mechanism that rotates according to a rotation operation of the dial operation unit and indicates operation setting information displayed on the design surface of the dial operation unit A thing including the above can be provided.

  Further, in the configuration in which the dial operation portion has a cylindrical tubular main body portion, the dial-side guide portion can be formed at the rear end portion of the tubular main body portion in the rotation axis direction. Thereby, the dial side guide part can be provided in a form that effectively utilizes the structure of the dial operating device. Further, in this configuration, since the dial side guide portion is formed at a relatively outer position, the formation region of the guide portion is widened and the structure is supported stably with respect to the support base.

  Further, in a configuration in which the dial operation portion has a cylindrical tubular main body portion, the support base is disposed inside the cylindrical main body portion of the dial operation portion so that the radial displacement of the cylindrical main body portion is reduced. It is possible to provide a position deviation restricting portion for restricting the above. According to this configuration, the dial operation unit can be stably held by the misregistration regulating unit.

  Either or both of the dial-side guide part and the base-side guide part can be formed in a form having a notch section in which a section is notched in the rotational operation direction. When the guide portion is formed to have a notch section, the sliding surface formed in the guide section is also interrupted in the section. The lubricant applied to the sliding surface flows mainly along the rotating sliding surface as the dial knob rotates. Easy to leak. However, in the present invention in which the lubricant accommodating recess is formed, the lubricant can be held for a long time even if there is such a discontinuous section on the sliding surface.

  Further, when a notch section is formed in the guide portion having the lubricant accommodating recess, the guide portion is accommodated in the lubricant accommodating recess at a circumferential end adjacent to the notch section in the rotational operation direction. A lubricant outflow prevention wall portion for preventing the lubricant flowing out into the notch section can be formed. Accordingly, it is possible to prevent the lubricant from being pushed out into a section where the sliding surface is interrupted in accordance with the rotation operation of the dial knob, so that the lubricant can be held for a long period of time.

  Further, the notch section of the guide portion can be formed so as to appear as a pair at a position that is symmetric with respect to the rotation axis on the projection plane orthogonal to the rotation axis direction. Since the guide portion is formed as a support portion for supporting the dial operation portion on the support base, the guide portion can be stably supported by being formed symmetrically as described above.

  When the base-side guide part is formed with a notch section in the rotational operation direction, an outer peripheral side structure that is not rotated with respect to the rotational operation of the dial operation part is disposed in the notch section area of the support base. Can do. When a switch device is provided on the support base in addition to the dial type operation device, it may be necessary to arrange the operation devices in a compact manner due to design restrictions and to make the whole compact. In particular, when the above-described internal structure and outer peripheral structure are provided, it is particularly necessary to secure a space for arranging them. According to the said structure, a structure can be arrange | positioned in the notch area of a base | substrate side guide part. In other words, a notch section can be provided in the base-side guide portion in order to arrange the structure on the support base. Thereby, since it becomes possible to arrange a structure using a notch section, a plurality of switch devices can be located densely, and the whole can be made compact. As the outer peripheral side structure, one of an angular position holding mechanism that holds the dial operation unit at a plurality of predetermined angle holding positions, and a rotational operation angular position detection mechanism that detects the rotational operation angular position of the dial operation unit, or Both can be provided simultaneously.

On the other hand, the pointer transparent disc portion 61 receives light from the LED 81 located rearward in the direction of the rotation axis X, so that only the pointer portion 61a (see FIG. 1) is turned on. The pointer transparent disk unit 61 is rotated by a rotation driving unit (not shown) in conjunction with the rotation operation of the dial operation unit 10 to instruct the graphic display unit on the graphic display panel 71. That is, the internal structure 60 in the present embodiment is configured as a design surface-emission display mechanism that uses a light source that is located rearward in the rotation axis direction, and a pointer position driving mechanism.

  A dial-side guide portion 11 is formed at the rear end portion of the dial operation portion 10 in the rotation axis X direction. On the other hand, the support base 20 is formed with a base-side guide portion 21 that engages with the dial-side guide portion 11, and the contact surface 110 of the dial-side guide portion 11 slides on the base-side guide portion 21 in the engaged state. When it is in contact with the moving surface 210 and is rotated, the dial operation unit 10 is guided to rotate and slide in such a manner that the engaged state is maintained.

  The base-side guide portion 21 is formed as a slide rail that protrudes forward in the direction of the rotation axis X. On the other hand, the dial-side guide portion 11 is formed in a groove shape that engages with the rail-shaped base-side guide portion 21. More specifically, the dial-side guide portion 11 is formed as a pair of groove-forming ridges that protrude rearward in the direction of the rotation axis X across the contact surface (groove bottom surface) 110 with the base-side guide portion 21. ing.

  A plurality of detection targets are detected along the operation path on the front end surface 112 of one of the pair of groove-forming protrusions forming the dial-side guide portion 11 (in this embodiment, the radially inner protrusion) 102. A detected body unit 13 in which the body 13g is arranged at a predetermined arrangement interval corresponding to the operation displacement detection interval of the dial operation unit 10 is provided.

  As shown in FIG. 4, the detected body unit 13 is formed by arranging the detected bodies 13 g along an annular path along the circumferential direction of the dial operation unit 10. Is added to the operation detection unit 30 (see FIG. 3A) along the operation path. Specifically, the detected body unit 13 is a convex row 13G in which a plurality of main biasing portions for urging the switch forming the detected body 13g are arranged at predetermined intervals. In this embodiment, the dial operation unit 10 has a cylindrical main body 12, and the end surface on the operated side (the front side in the rotation axis X direction) in the rotation axis X direction of the dial operation unit 10 is the first end surface. When the end surface on the side of the support base 20 on the opposite side (the rear side in the direction of the rotation axis X) is the second end surface, the convex row 13G is formed on the second end surface of the dial operation unit 10.

  The operation detection unit (rotational operation angle position detection mechanism) 30 detects the detected body 13g that sequentially arrives with the relative movement with respect to the detected body unit 13 from the arrival of the detected body 13g in the normal operation direction and the arrival in the reverse operation direction. It is configured so that it can be detected separately. As shown in FIG. 7, the operation detection unit 30 includes a lever member 31 that is disposed to face the main convex portion 13 g, a cam member 33 that receives an urging force from the lever member 31, a terminal 35, and a cam member. The terminal contact piece 36 is configured to be elastically deformable so that the state of contact with the terminal 35 changes as the terminal 33 is energized, and the case 34 accommodates these.

  The terminal 35 includes a first side terminal 35a, a common terminal 35b, and a second side terminal 35c, which are arranged in a line in this order. In the non-operating state of the lever member 31, as shown in FIG. 7A, the contacts 36a and 36b of the terminal contact piece 36 are both in contact with the common terminal 35b, and between these terminals 35a, 35b and 35c. No current flows. However, as shown in FIG. 7B, the lever member 31 is urged in the forward rotational operation direction with the arrival of the main convex portion 13g accompanying the forward rotational operation of the dial operation unit 10, and the cam member 33 elastically deforms the terminal contact piece 36 in the case 34. At this time, the contacts 36 a and 36 b slide on the lower surface of the case 34. As a result of this sliding, the contact 36a of the terminal contact piece 36 contacts the common terminal 35b, while the contact 36b of the terminal contact piece 36 contacts the second side terminal 35c. Thereby, between the common terminal 35b and the 2nd terminal 35b will be in an energized state. On the other hand, as shown in FIG. 7C, the lever member 31 is urged in the reverse rotation operation direction with the arrival of the main projection 13g due to the reverse rotation operation of the dial operation unit 10, and the cam The member 33 elastically deforms the terminal contact piece 36 in the case 34. At this time, the contacts 36a and 36b slide the lower surface of the case 34 in the direction opposite to that during the forward operation. As a result of this sliding, the contact 36a of the terminal contact piece 36 contacts the first side terminal 35a, while the contact 36b of the terminal contact piece 36 contacts the common terminal 35b. Thereby, between the 1st side terminal 35a and the common terminal 35b will be in an energized state. In a controller (not shown), the rotation operation angle to the dial operation unit 10 is acquired based on the change in the energized state in a form that identifies forward rotation and reverse rotation. That is, the operation detection unit 30 according to the present embodiment is configured so that the output of the switch contacts 36a and 36b corresponding to the rotation operation direction is the lever member as the main projection 13g sequentially arrives due to the rotation operation displacement of the dial operation unit 10. It is configured as a bidirectional pulse switch that changes in a pulse shape between an energized output state to 31 and a non-energized output state.

  A plurality of dial operation parts 10 are provided on the other protrusion part 101 (the radially outer protrusion part in this embodiment) of the groove-forming protrusion part pair 11 in a state in which the dial operation part 10 is allowed to rotate. Angular position holding means 40 for holding at any one of the angular holding positions is provided. Each angle holding position is set to a plurality of different angular positions around the rotation axis X with respect to the dial operation unit 10 in the configuration in which the dial operation unit 10 is rotated.

  The angular position holding means (angular position holding mechanism) 40 is configured as follows. That is, as shown in FIG. 8, on the second end surface of the dial operation unit 10, the position holding sliding surface 111 is provided in the rotational circumferential direction of the dial operation unit 10, separately from the convex row 13 </ b> G of the detected unit 13. The position around the rotation axis X is fixed on the support base 20 at a position facing the position-holding sliding surface 111, and the position is held at the tip of the support base 20 as the dial operation unit 10 rotates. A sliding member 41 for position holding that slides relative to the sliding surface 111 is provided. The angular position holding means 40 includes a position holding convex portion 41t protruding forward in the rotation axis X direction in the holding sliding member 41, and a concave row 15G composed of a plurality of position holding concave portions 15g fitted to the position holding convex portion 41t. And is configured. When the dial operation unit 10 is in an angle phase corresponding to the angle holding position, the position holding convex part 41t is fitted into the position holding concave part 15g, and the position holding convex part 41t is moved by applying a rotation operation in this state. The position holding recess 15g is detached from the angle holding position in such a way that it elastically climbs over the corresponding edge in the rotational direction. According to this configuration, the angle holding effect is enhanced by the fitting between the position holding convex portion 41t and the position holding concave portion 15g, and the position holding convex portion 41t corresponds to the position holding concave portion 15g when detached from the angle holding effect. Since moderate moderation resistance is developed when the edge is elastically overcome, the operability at the time of aligning the dial operation unit 10 at a desired angle is also improved. Note that the position holding recess 15g has a shape that is recessed in a curved shape, so that the position holding protrusion 41t can be easily moved over elastically with a rotation operation.

  Further, an auxiliary elastic member 42 is provided that elastically urges the position holding convex portion 41t of the position holding sliding member 41 in the direction of fitting the position holding concave portion 15g at the angle holding position. Accordingly, the position holding convex portion 41t is separated from the position holding concave portion 15g against the biasing force by the auxiliary elastic member 42 and is pressed by the elastic biasing force in accordance with the rotation operation of the dial operation unit 10. To slide relative to the position holding sliding surface 15f. In this case, by appropriately adjusting the elastic constant of the auxiliary elastic member 42, the moderation resistance feeling when the position holding convex portion 41t elastically climbs over the corresponding edge of the position holding concave portion 15g can be adjusted to an appropriate value. Due to the sliding friction caused by the elastic urging force, it is possible to prevent the dial operation unit 10 from changing its angular position due to a small external force or vehicle vibration.

  In the configuration of the present embodiment, the auxiliary elastic member 42 is constituted by a coil spring and is disposed inside the case 43, and the position-holding sliding member 41 places the auxiliary elastic member 42 in the rear position in the rotation axis X direction. And the position holding projection 41t is accommodated in the case 43 so as to protrude forward in the direction of the rotation axis X.

  The case 43 that accommodates the position-holding sliding member 41 and the operation detection unit 30 are press-fitted and fixed in openings 49 and 39 provided in the support base 20. These openings 49 and 39 are provided in a non-formation region of the base-side guide portion 21 formed on the support base 20 along the rotational circumferential direction of the dial operation portion 10. That is, the base-side guide portion 21 is formed to have cutout sections L1 and L2 that are partially cut out in the rotational operation direction of the dial operation section 10, and the cutout sections L1 and L2 of the support base 20 are formed. Openings 49 and 39 are formed in a region corresponding to the above, and non-rotating outer peripheral structures 30 and 40 are fixedly arranged in the openings 49 and 39 with respect to the rotation operation of the dial operation unit 10. Note that the notch sections L1 and L2 of the guide portion in the present embodiment are formed so as to appear in pairs at positions symmetrical with respect to the rotation axis X on the projection plane orthogonal to the direction of the rotation axis X.

  By the way, the dial type operating device 1 of the present invention has a lubricant containing recess 100 in at least one of the sliding surface 210 of the support base 20 and the contact surface 110 of the dial operating unit 10 that contacts the sliding surface 210. It is characterized by being formed. In the present embodiment, as shown in FIG. 9, the sliding surface 210 is formed on the distal end surface 210 of the base-side guide portion 21 of the support base 20. As shown in FIGS. 5 and 10, the lubricant accommodating recess 100 in the present embodiment is formed in a groove shape that is continuous along the rotational operation direction of the dial operation unit 10.

  However, the base-side guide portion 21 is formed in a shape having cutout sections L1 and L2 in which some sections are cut out in the rotational operation direction of the dial operation section 10, and the lubricant containing recess 100 is connected in an annular shape. It is not a different shape. For this reason, in the guide portion 21 in which the lubricant accommodating recess 100 is formed, the lubricant accommodating recess 100 is accommodated at the circumferential end adjacent to the notch sections L1 and L2 in the rotational operation direction of the dial operation portion 10. A lubricant outflow prevention wall portion 211 is formed to prevent the lubricant from flowing out into the notch sections L1 and L2. Further, as shown in FIG. 10, the lubricant accommodating recess 100 in the present embodiment is formed so as to appear in a U shape on a cut surface by a plane including the rotation axis X. In addition, you may form so that it may show V shape in the cut surface by the plane containing the rotating shaft X. As a result, the lubricant outflow prevention wall portion 212 is also formed in the radial direction of the cylindrical positional displacement restricting portion 22, so that the lubricating oil retaining effect is further increased.

  As mentioned above, although 1st embodiment of this invention was described, these are only illustrations, this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. It is. In the following, another embodiment of the present invention will be described. Note that the description of the same functional part is omitted by using the same reference numerals.

It is formed as 1000. Other configurations are the same as those in the first embodiment.

  12, 13 and 14 are views showing a third embodiment of the present invention. The dial type operating device 1 shown in FIG. 12 does not have the internal structure 60 provided inside the dial operating unit 10 in the first embodiment. For this reason, as shown in FIG. 13 (CC sectional view and DD sectional view in FIG. 12), the dial operation unit 10 includes a front end 18 that forms a design surface of the dial operation unit 10. A rotation shaft portion 14 extending rearward of the rotation axis X is formed, and a dial side guide portion 15 is formed at the tip portion thereof. On the other hand, a base-side guide portion 25 that engages with the dial-side guide portion 15 is formed at a position corresponding to the rotating shaft portion 14 of the support base 20. The dial-side guide portion 15 in the present embodiment is a protruding ridge (guide rail) continuously formed in an annular shape, while the base-side guide portion 25 is continuous in an annular shape engaged with the protruding ridge portion 15. It is formed as a groove. Specifically, the base-side guide portion 25 is formed as a pair of groove-forming ridge portions 23 and 24 that are formed to protrude forward in the rotation axis X direction with the dial-side guide portion 15 interposed therebetween.
