As shown in FIG. 4, the switch device 30 includes a switch body 40, a switch operation unit 60, and a shaft member 80 that connects the switch body 40 and the switch operation unit 60. As shown in FIG. 4, the switch body 40 has a box shape that is long in the vehicle longitudinal direction (X-axis direction).

  The switch body 40 is attached to an opposing wall 21A facing the trim board 12 (vehicle door 10) among the walls constituting the pull handle 21 by attachment means (not shown) such as screws. . The pull handle 21 may be configured as an integral part of the armrest 20 (in this case, the upper wall portion 20A of the armrest 20 shown in FIG. 2 constitutes a part of the pull handle 21). That is, the “pull handle” referred to here is an opening formed on the upper surface of the armrest 20. In addition, about the attachment location of the switch main-body part 40, it is not limited to 21 A of opposing wall parts, What is necessary is just a wall part which opposes the vehicle door 10 among the wall parts which comprise the pull handle 21. FIG. For example, the switch body 40 may be attached to the upper wall portion 20A of the armrest 20 shown in FIG.

  The switch operation unit 60 is operated by an occupant gripping it and moving the switch main body unit 40 with respect to the switch body unit 40 to operate the devices arranged in the vehicle interior (details will be described later). As shown in FIG. 4 or FIG. 5, the switch operation unit 60 has a longitudinal shape, and the switch main body portion 40 has a longitudinal direction that coincides with the vehicle front-rear direction (X-axis direction, left-right direction in FIG. 5). Is attached.

  The shape of the switch operation unit 60 will be described in detail. The switch operation unit 60 has a shape in which the length in the vertical direction (Z-axis direction) becomes smaller toward the vehicle front side (left side in FIG. 7) as shown in FIG. There is no. As shown in FIG. 6, the switch operation unit 60 includes an outer peripheral wall portion 60 </ b> E opened on the switch main body portion 40 side, and a side wall arranged so as to cover the opening portion of the outer peripheral wall portion 60 </ b> E from the switch main body portion 40 side. 60A. In addition, 60 A of side wall parts are attached to the outer peripheral wall part 60E by fastening means, such as the screw 60F, for example (refer FIG. 4).

  In the outer peripheral wall portion 60E of the switch operation portion 60, a tip portion 61 that protrudes forward is provided at the front portion of the vehicle as shown in FIG. The surface of the distal end portion 61 has a continuous substantially triangular wave shape (a jagged shape) in a cross-sectional view, and is easy to be gripped by an operator (occupant).

  As shown in FIGS. 4 and 6, the switch operation unit 60 is attached to the switch body 40 via a shaft member 80. The shaft member 80 has a cylindrical shape extending in the Y-axis direction, and is attached to the switch body 40 so as to be rotatable around the Y-axis (details will be described later). The switch operation unit 60 can move in the X-axis direction and the Y-axis direction with respect to the shaft member 80 (in-plane movement on the XZ plane intersecting the extending direction of the shaft member 80 (Y-axis direction)). ). That is, the switch operation unit 60 is attached to the switch body 40 so as to be movable in the XZ plane and to be rotatable around the Y axis with the shaft member 80 as the rotation center.

  Next, the mounting structure of the switch body 40, the shaft member 80, and the switch operation unit 60 will be described in detail. As shown in FIG. 6, in the switch body 40, a through hole 40 </ b> B is formed in the side wall 40 </ b> A that faces the switch operation unit 60. In the switch operation unit 60, a through hole 60 </ b> B is formed in the side wall 60 </ b> A that faces the switch body 40. One end side of the shaft member 80 in the extending direction (Y-axis direction) is inserted into the through hole 40B of the switch main body 40, and the other end side is inserted into the through hole 60B of the switch operating unit 60.

  As shown in FIG. 6, the shaft member 80 is attached to the switch body 40 via the support member 41 in the vicinity of the center in the Y-axis direction. The support member 41 is formed so as to surround the entire circumference of the shaft member 80. With this support member 41, the shaft member 80 can rotate around the Y axis (the axial direction of the shaft member 80) and can move in the Y axis direction (direction approaching and separating from the switch body 40). Further, it is attached in a state where movement on the XZ plane is restricted. As such a support member 41, a bearing etc. can be illustrated, for example. The support member 41 may be any member as long as it can attach the shaft member 80 so as to be rotatable about the Y-axis and move in the Y-axis direction.

  A fitting rib 81 is formed at the end of the shaft member 80 on the switch body 40 side so as to protrude outward in the radial direction of the shaft member 80. The fitting ribs 81 are formed at two locations in the circumferential direction, and the two fitting ribs 81 are arranged at positions that are symmetrical by 180 degrees with respect to the axial center of the shaft member 80 (see FIG. 12). .

  As shown in FIGS. 6 and 12, a main body side contact member 42 having a long shape in the X-axis direction is disposed in the switch main body 40. An insertion hole 42A is formed in the central portion of the main body side contact member 42 in the X-axis direction so as to penetrate in the Y-axis direction. The insertion hole 42 </ b> A is configured such that both the fitting ribs 81 and the shaft member 80 are inserted, and has a shape that allows the both fitting ribs 81 of the shaft member 80 to be fitted. Accordingly, when the shaft member 80 rotates about the Z axis, the main body side contact member 42 is configured to rotate coaxially with the rotation axis of the shaft member 80.

  As shown in FIG. 12, on the lower surface of the main body side contact member 42, movable side contacts 42B are formed at both ends in the X-axis direction. On the other hand, in the switch body 40, each support base 45 is installed on a support plate 43 extending in the vehicle front-rear direction, and is fixed to the upper surface portion of each support base 45 so as to face each movable contact 42B. Side contacts 45B are respectively formed.

  In an initial state where the switch operation unit 60 is not operated (the state shown in FIGS. 7 and 12), the main body side contact member 42 is in a horizontal state (a state along the X axis), and each movable side contact 42B. And the fixed contact 45B are not in contact with each other. In addition, on the upper surface of the main body side contact member 42, both end portions in the X-axis direction (above the formation portion of the movable contact 42B) are respectively descending inclined surfaces 42D that are inclined downward toward the respective end portions. A spring member 46 is disposed between each downwardly inclined surface 42D and the upper wall portion 40D of the switch main body 40.

  Each spring member 46 is arranged in a state where the length is shorter than the natural length (or the same length as the natural length) when the main body side contact member 42 is horizontal. Further, positioning ribs 46 </ b> A are formed on the upper wall portion 40 </ b> D of the switch main body portion 40 and the descending inclined surface 42 </ b> D of the main body portion side contact member 42 so as to surround each spring member 46. Each spring member 46 is arranged in each positioning rib 46A, whereby each spring member 46 is positioned in the horizontal direction (XY direction).

  The natural length and the spring constant of both spring members 46 are set to the same value, for example. Moreover, the distance from the shaft member 80 in the X-axis direction of each spring member 46 is set at the same distance. As a result, in a state where no force is applied to the switch operation unit 60 (initial state), the downward pressing force acting from both the spring members 46 to the main body side contact member 42 becomes equal. As a result, the rotational moment around the shaft member 80 acting on the main body side contact member 42 from each spring member 46 becomes equal, and the main body side contact member 42 is held in a horizontal state. That is, the two spring members 46 have a function of holding the main body side contact member 42 in a horizontal state.

  With the above configuration, the switch operating unit 60 (and thus the shaft member 80) is rotated clockwise (in the direction indicated by R1 in FIG. 12) in FIG. In this case, the main body side contact member 42 rotates in such a way that the right side is in a low state, and as a result, the right movable side contact 42B and the fixed side contact 45B come into contact (electrically connected). It has a configuration.

  At the same time, the left spring member 46 contracts, and the right spring member 46 extends from the natural length (in the case where the right spring member 46 is arranged in the natural length in the horizontal state, the natural length remains the same). . When the occupant releases his hand from the switch operation unit 60, the spring member 46 on the left side is elastically restored, so that the main body side contact member 42 returns to a horizontal state (the movable side contact 42B and the fixed side contact 45B are in contact with each other). Non-contact state).

  Further, when the shaft member 80 (and thus the switch operation unit 60) rotates counterclockwise in FIG. 12 (in the direction indicated by R2 in FIG. 12) from the horizontal state of the main body side contact member 42, it is movable on the left side. When the side contact 42B and the fixed side contact 45B come into contact with each other and the occupant releases the hand from the switch operation unit 60, the main body side contact member 42 returns to a horizontal state.

  Next, a mounting structure between the shaft member 80 and the switch operation unit 60 will be described. As shown in FIGS. 6 and 11, a shaft-side contact forming member 83 is extrapolated at the end of the shaft member 80 on the switch operation unit 60 side. As shown in FIGS. 7 and 8, the shaft-side contact forming member 83 has a substantially cross shape in a side view. Specifically, the shaft-side contact forming member 83 has a circular main body 83A and a peripheral end of the main body 83A. 8A and 8B, and projecting portions 83B projecting in the four directions (X-axis and Z-axis directions) in the up, down, left and right directions of FIG. And from the protrusion end of each protrusion part 83B, it forms in the form from which the shaft side contact 83D protrudes, respectively. The shaft side contact 83D has a hemispherical tip.

  As shown in FIG. 7, as shown in FIG. 7, the operation unit side contact forming member 62 having a side view in the side wall portion 60 </ b> A (the side wall portion facing the switch main body portion 40) in the switch operation unit 60 inside the switch operation unit 60. Is attached. A through hole 62A is formed in the operation part side contact forming member 62 so as to penetrate a position overlapping the through hole 60B in a side view. As shown in FIG. 7, the through-hole 62 </ b> A has a substantially circular shape that can accommodate the shaft-side contact forming member 83 therein.

  And the groove part 62B is each formed in the inner peripheral wall which comprises 62 A of through-holes so that it may dent in the up-down and left-right directions of FIG. Each shaft side contact 83D is arranged in each groove 62B. And operation part side contact 62D is formed in the back wall of each groove part 62B, respectively.

  Spring members 83E are externally attached to the shaft side contacts 83D. Each spring member 83E is in contact with the projecting end of the projecting portion 83B on one end side and the rear wall of the groove portion 62B on the other end side. Thus, when the occupant (operator) operates the switch member 60 in any of up / down / left / right directions with respect to the shaft member 80 fixed in the up / down / left / right direction, as shown in FIG. Of these, the shaft side contact 83D contacts the corresponding operation unit side contact 62D while contracting the spring member 83E opposite to the operation direction of the switch operation unit 60. For example, as shown in FIG. 9, when the switch operation unit 60 is operated upward with respect to the shaft member 80, the lower spring member 83 </ b> E is contracted and the lower shaft side contact 83 </ b> D is opposed to the operation unit side. It is the structure which contacts the contact 62D.

  When the occupant releases his / her hand from the switch operation unit 60 and the operation force to the switch operation unit 60 is released, the contracted spring member 83E is elastically restored, and the shaft-side contact forming member 83 is moved to the initial position ( In other words, each shaft side contact 83D and each operation unit side contact 62D return to the non-contact position). That is, each spring member 83E is an urging unit that urges the switch operation unit 60 toward the initial position (a position where the center of the through hole 62A and the center of the shaft member 80 overlap in a side view).

  As shown in FIG. 6, in the shaft member 80, a rotation transmission member 84 is extrapolated at a position that is closer to the switch main body 40 than the shaft-side contact forming member 83. As shown in FIG. 10, the rotation transmitting member 84 has a substantially cross shape when viewed from the side. Specifically, the rotation transmitting member 84 has a circular main body portion 84A and a peripheral end of the main body portion 84A. Projecting portions 84B projecting in the four directions of up, down, left and right.

  As shown in FIG. 10, in the switch operation unit 60, a wall portion 60D attached to the side wall portion 60A is disposed around the rotation transmission member 84 in a side view. A transmission member fitting hole 63 corresponding to the shape of the rotation transmission member 84 is formed in the wall portion 60 </ b> D so as to penetrate in the axial direction (Y-axis direction) of the shaft member 80.

  The transmission member fitting hole 63 includes a circular main body portion 63A and a concave portion 63B formed in such a manner that the inner peripheral surface of the main body portion 63A is recessed in four directions, up, down, left, and right in FIG. Yes. Each protrusion 84B is arranged in a form that fits into each recess 63B. With this configuration, when the switch operation portion 60 (and thus the wall portion 60D) rotates with respect to the shaft member 80, the inner surface of each recess 63B comes into contact with the outer surface of each protrusion 84B, and the shaft The member 80 is configured to rotate in the axial direction. That is, the rotation transmitting member 84 has a function of transmitting the rotation to the shaft member 80 when the switch operation unit 60 is rotated.

  Accordingly, the shaft member 80 is rotated via the rotation transmission member 84 when the occupant rotates the switch operation unit 60. As the shaft member 80 is rotated, the main body side contact member 42 is rotated as described above, and the movable contact 42B and the fixed contact 45B corresponding to the rotation direction are in contact with each other. .

  As shown in FIG. 10, the diameter of the main body portion 63A of the transmission member fitting hole 63 is set to be larger than the diameter of the main body portion 84A of the rotation transmission member 84, and the main body portion 84A is formed of the main body portion 63A. There is a gap between the inner peripheral surface. Further, the projecting portion 84B has a gap with the concave portion 63B. The switch operation unit 60 is allowed to move in the vertical and horizontal directions (on the plane intersecting the extending direction of the shaft member 80) with respect to the shaft member 80 by the gaps. The shaft member 80, the shaft side contact forming member 83, and the rotation transmitting member 84 may be formed as an integral part.

  As shown in FIG. 7, in the upper part of the outer peripheral wall portion 60E of the switch operation portion 60, a columnar operation portion 67 is rotatably attached to a location on the vehicle front side via a rotation shaft 67A. . As shown in FIG. 5, the operation portion 67 is attached such that a part of the outer peripheral surface is exposed to the outside of the outer peripheral wall portion 60 </ b> E, and can be rotated by the operator. The switch operation unit 60 includes a sensor unit 68 having three detection pins 68A. For example, when each detection pin 68A is in electrical contact with the operation unit 67, the rotation amount and the rotation direction of the operation unit 67 are provided. Is configured to detect.

  Next, the electrical configuration of the switch device 30 of the present embodiment will be described. A control circuit board (not shown) is accommodated in the switch body 40. Each operation unit side contact 62D of the switch operation unit 60 is electrically connected to the control circuit board. Thereby, each operation part side contact 62D of the switch operation part 60 comes into contact with each corresponding shaft side contact 83D, so that an electrical signal corresponding to each operation part side contact 62D is transmitted to the control circuit board. ing. That is, operation information indicating that the switch operation unit 60 is operated in the X-axis direction or the Z-axis direction (up / down / left / right direction in FIG. 7) by the operation unit side contacts 62D and the axis side contacts 83D (movement of the switch operation unit 60). The X-axis direction and the Z-axis direction are examples of information detection directions in the switch device 30.

  For example, as shown in FIG. 9, when the switch operation unit 60 is moved upward with respect to the shaft member 80 (and thus the switch body 40), the lower shaft side contact 83D and the lower side contact 83D The operation unit side contact 62D comes into contact, and an electrical signal corresponding to the contact is transmitted to the control circuit board. Accordingly, it is possible to detect operation information that the switch operation unit 60 has been operated upward.

  The fixed side contact 45B of the switch body 40 is electrically connected to the control circuit board. When each movable side contact 42B comes into contact with each fixed side contact 45B, an electric signal corresponding thereto is sent to the control circuit board. It is the composition transmitted to. Thereby, it is possible to detect operation information (operation information based on movement of the switch operation unit 60) that the switch operation unit 60 has been rotated around the Y axis. That is, each rotation direction around the Y axis (indicated by an arrow R1 or R2 in FIG. 12) is an example of an information detection direction in the switch device 30.

  The sensor unit 68 of the switch operation unit 60 is electrically connected to the control circuit board, and an electric signal based on operation information such as a rotation direction and a rotation amount of the operation unit 67 is transmitted to the switch body unit 40. Is transmitted to the control circuit board.

  The control circuit board is electrically connected to various devices (not shown) installed in the vehicle, and can operate various devices based on the operation information of the switch operation unit 60. . In the present embodiment, with the initial state shown in FIG. 7 as a reference, for example, a window glass (not shown) is turned by rotating the switch operation unit 60 in a direction in which the distal end portion 61 of the switch operation unit 60 faces upward. The window glass can be lowered by rotating the switch operation portion 60 in a direction in which the tip portion 61 faces downward.

  In addition, a display operation is performed on a monitor (not shown) installed on the rear surface of the vehicle seat by the rotation operation of the operation unit 67 of the switch operation unit 60 and the operation of the switch operation unit 60 in the Z-axis direction and the X-axis direction. Various devices can be operated while referring to the displayed information (menu screen). Examples of operations of various devices include adjustment of the position and angle of a vehicle seat, operations of audio devices, lighting devices, air conditioners, and the like. The various devices operated by operating the switch operation unit 60 are not limited to the above.

  More specifically, it is possible to select which device to operate by rotating the operation unit 67. Further, by operating the switch operation unit 60 in the X-axis direction (left-right direction), operation items set for each device (for example, for a vehicle seat, each item such as seat position adjustment and seat angle adjustment). ) Can be selected.

  Then, after each item is selected, the switch operation unit 60 is operated in the Z-axis direction (vertical direction in FIG. 7), so that the parameters in the selected operation item (for example, if the sheet angle is adjusted, the sheet inclination angle). ) Can be adjusted. Note that the operation of various devices by the switch operation unit 60 illustrated here is an example, and it is possible to appropriately change to which device operation the operation in each direction of the switch operation unit 60 is assigned.

  Next, in the switch device 30 of the present embodiment, the configuration and operation of a lock mechanism provided to suppress erroneous operations will be described. As shown in FIG. 4, the locking mechanism is formed on the protrusion 65 formed on the side wall 60A of the switch operation unit 60 and on the side wall 40A of the switch main body 40 (the wall facing the side wall 60A). The concave portion 47 is mainly used.

  The protrusion 65 protrudes toward the side wall 40A of the switch body 40 and has a longitudinal shape extending in the vehicle front-rear direction. The concave portion 47 is formed in a longitudinal shape extending in the vehicle front-rear direction formed at a location facing the protrusion 65 and is configured to be fitted to the protrusion 65. As shown in FIG. 5, in the initial state, the switch main body 40 and the switch operation unit 60 are arranged with a gap in the Y-axis direction, and the projection 65 is arranged in a state of being detached from the recess 47. ing.

  As described above, the shaft member 80 is attached so as to be movable in the direction approaching and separating from the switch body 40 (the left-right direction in FIG. 11). As shown in FIGS. 6 and 11, a spring member 82 is externally attached to the end of the shaft member 80 on the switch body 40 side. One end of the spring member 82 is in contact with both fitting ribs 81 of the shaft member 80 and the other end is in contact with the inner surface of the side wall 40E (the side wall opposite to the side wall 40A). Has been. A positioning rib 48 is formed on the side wall portion 40E so as to surround the spring member 82. By arranging the spring member 46 in the positioning rib 48, the movement of the spring member 46 in the ZX plane is restricted (positioned).

  Next, the operation and effect of the lock mechanism in the switch device 30 of the present embodiment will be described. Here, an action that may occur when an occupant performs an operation of closing the vehicle door 10 is illustrated. When the occupant inserts his hand into the pull handle 21 from the inside of the vehicle and pulls the vehicle door 10 toward the vehicle interior side, the occupant's hand touches the switch operation unit 60, and the switch operation unit 60 is connected to the switch body 40 side ( There is a case where it is pressed (operated) in the Y-axis direction in a direction approaching the switch body 40 and a direction intersecting the information detection direction.

  When the switch operation unit 60 is pressed toward the switch main body 40, the switch operation unit 60 and the shaft member 80 are moved toward the switch main body 40 from the initial state shown in FIG. Then, the protrusion 65 fits into the recess 47 (state shown in FIG. 3). At this time, the spring member 82 is pressed by the shaft member 80 and the side wall portion 40E to be contracted from the natural length.

  By fitting the protrusion 65 into the recess 47, the rotation of the switch operation unit 60 relative to the switch body 40 and the movement in the vertical and horizontal directions (in-plane movement on the XZ plane) are restricted. From the above, when the occupant touches the switch operation unit 60 when using the pull handle 21 and the switch operation unit 60 is operated in a direction crossing the information detection direction, the movement of the switch operation unit can be restricted. .

  When the occupant releases his / her hand from the switch operating unit 60 and the pressing of the switch operating unit 60 is released, the contracted spring member 82 is elastically restored, so that the switch operating unit 60 is in the initial position (FIG. 2, FIG. 6. Return to the position of FIG. That is, the spring member 82 is a biasing unit that biases the switch operation unit 60 toward the initial position (a position where the protrusion 65 is not fitted in the recess 47).

  The switch operation unit 60 is attached to the switch body 40 so as to be rotatable and movable in the plane. In this way, the operation information can be detected based on the rotation and in-plane movement of the switch operation unit 60. That is, the operation of the in-vehicle device connected to the switch device 30 can be performed by the operation of rotation and in-plane movement.

  In the present embodiment, both the protrusion 65 and the recess 47 have a longitudinal shape (a shape extending in the X-axis direction). With such a shape, when both members are fitted, the outer surface of the protrusion 65 and the inner surface of the recess 47 abut each other at at least two locations. Thereby, the rotation of the switch operation unit 60 and the in-plane movement can be more reliably regulated. If the projection 65 is cylindrical or the like, there is a risk that the switch operation unit 60 may rotate around the projection 65 fitted in the recess 47, but if this is a longitudinal shape as in this embodiment, this Such a situation can be suppressed.

  The switch device 30 of this embodiment is installed inside the pull handle 21. For this reason, a seated occupant can easily reach the switch operation unit 60 and has good operability. On the other hand, there is a concern that the occupant may touch the switch operation unit 60 because it is installed inside the pull handle 21 where the hand can be easily extended. In this regard, in the present embodiment, since the above-described locking mechanism is provided, it is possible to suppress erroneous operations and is effective.

The present invention is not limited to the embodiments described with reference to the above description and drawings. For example, the following embodiments are also included in the technical scope of the present invention.

  (1) In the above embodiment, the information detection direction of the switch operation unit 60 is exemplified as the up / down / left / right direction and the rotation direction, but is not limited to these directions.

  (2) In the above embodiment, the Y-axis direction is exemplified as the direction intersecting with the information detection direction, but the present invention is not limited to this.

  (3) In the embodiment described above, the configuration in which the protrusion 65 and the recess 47 are fitted as an example of the lock mechanism is illustrated, but the present invention is not limited to this. For example, the lock mechanism includes a sensor (for example, an electrostatic sensor or a displacement sensor) that detects that the switch operation unit 60 is operated in a direction intersecting the information detection direction with respect to the switch main body unit 40, and the sensor. It is good also as a structure provided with the control means (for example, electromagnetic brake etc.) which receives the detection signal of and controls rotation of the shaft member 80.

  (4) In the above embodiment, an elastic member such as rubber may be used instead of the spring members 46, 82, 83E.

  (5) The protrusion 65 may be formed in the switch body 40 and the recess 47 may be formed in the switch operation unit 60.
