JP 10-169309 A

  However, in this conventional vehicle window switch unit, since the vehicle window selection switch and the operation knob are arranged in parallel on the base member, there is a concern that the base member becomes larger and the occupied area in the vehicle becomes larger. The

  In general, when driving a vehicle, for example, when a passenger is on the front seat only, the rear window window operation is not necessary. However, in the conventional vehicle window switch unit, Even in such a situation, since a plurality of vehicle window selection switches are disposed, there is a possibility that the vehicle window selection switch on the rear seat side is erroneously pressed and the vehicle window on the rear seat side is opened and closed.

  Accordingly, the present invention is intended to provide a vehicle window switch unit capable of miniaturizing the entire unit and preventing erroneous operation.

In order to achieve the above object, the invention described in claim 1 is directed to an operation knob (for example, in an embodiment described later) for operating a vehicle window opening / closing drive circuit (for example, an elevation drive circuit 11, 12 in an embodiment described later). In a vehicle window switch unit that includes operation knobs 8 and 9 and operates a plurality of vehicle window opening / closing drive circuits on one unit, it can be slid to a base member (for example, a unit case 4 in an embodiment described later). A slide member (for example, a slide panel 6 in an embodiment described later) that is attached and restricts the operation of a specific vehicle window opening / closing drive circuit according to the slide position is provided, and the operation knob is disposed on the slide member , On the slide member, a plurality of operation knobs corresponding to different vehicle windows along the slide operation direction (for example, in embodiments described later) The operation knobs 9A and 9B) are arranged in parallel, and the operation of the operation knob is restricted by covering the base member almost completely above the specific operation knob at one slide position of the slide member. A limiting wall (for example, the limiting wall 20 in the embodiment described later) is provided .

In this case, since the operation knob is disposed on the slide member that is slid on the base member, the base member can be reduced in size. In addition, the opening / closing drive circuit of a specific vehicle window that is not used can be limited by the position operation of the slide member.
Further, when the slide member is slid to one side, the operation of the operation knob corresponding to the specific vehicle window is physically restricted by the restriction wall, and only the remaining operation knobs can be operated.

  According to a second aspect of the present invention, in the first aspect of the present invention, a contact switching mechanism (for example, described later) between the slide member and the base member that switches the contact according to the slide position of the slide member. The contact switching mechanism 10) in the embodiment is provided, and the electrical contacts of the operation knob are selectively connected to the opening / closing drive circuits of the plurality of vehicle windows by the contact switching mechanism.

  In this case, the contact switching mechanism selectively connects the electrical contact of the operation knob to one of the open / close drive circuits according to the slide position of the slide member. As a result, only the opening / closing drive circuit of the selected vehicle window can be operated by the operation knob, and the remaining opening / closing drive circuit cannot be operated.

According to the first aspect of the present invention, since the operation knob is arranged on the slide member that is slid on the base member, the base member can be downsized to reduce the size of the entire unit. Since the operation of the opening / closing drive circuit for the specific vehicle window can be restricted by the slide position of the slide member, unintentional erroneous operation of the vehicle window can be prevented in advance.
In addition, when the slide member is slid in one direction, the operation of the operation knob corresponding to the specific vehicle window is physically restricted by the restriction wall, so that the structure is simplified while preventing erroneous operation and miniaturizing the unit. The increase in manufacturing cost can be suppressed by the conversion.

  According to the second aspect of the present invention, since the operation of the opening / closing drive circuit of the vehicle window that is not used can be limited only by providing a contact switching mechanism that switches according to the slide position of the slide member, Can be further advantageously reduced.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, unless otherwise specified, “front” and “rear” refer to the front and rear in the direction of travel of the vehicle, and the same applies to “left” and “right” in the direction of travel of the vehicle. It shall point to the left and right of In the drawing, an arrow F indicates the front side.

1 to 4 show a window switch unit 1 according to a reference example of the present invention. The window switch unit 1 is attached to, for example, a door trim portion of a side door on the driver's seat side, and can move up and down the left and right window glasses of the front seat and the rear seat by operation on the unit. .

  The window switch unit 1 has a concave portion 5 formed on the upper surface side of a unit case 4 (base member) that accommodates an elevation operation mechanism 2 and a circuit board (elevation switch circuit 3 and the like), and a slide panel 6 ( A slide member) is attached. The slide panel 6 is guided by a guide groove 7 formed on the side wall in the recess 5, and can be slid along substantially the front-rear direction of the vehicle body. On the slide panel 6, a left operation knob 8 and a right operation knob 9 corresponding to the left and right vehicle windows are arranged side by side in the width direction. These operation knobs 8 and 9 actuate the right and left lifting operation mechanisms 2 in the unit case 4 by a raising operation and a tilting operation with one end side as a rotation fulcrum.

  Each lifting / lowering operation mechanism 2 is a mechanism for operating the lifting / lowering switch circuit 3 corresponding to the left and right vehicle windows, and each of the left / right lifting / lowering switch circuits 3 is connected to the front and rear window glass lifting / lowering drive circuits 11 through the contact switching mechanism 10. 12 (open / close drive circuit). Here, the operation knobs 8 and 9 and the corresponding elevation operation mechanism 2, elevation switch circuit 3, contact switching mechanism 10 and the like have the same configuration except for the left and right. For this reason, the following description will be made by taking the right-side vehicle window shown in FIGS. 3 and 4 as an example.

  The contact switching mechanism 10 includes a movable contact 13 disposed on the lower surface of the slide panel 6 and switching contacts 14A and 14B disposed on the upper surface of the unit case 4. The contact switching mechanism 10 is movable according to the slide position before and after the slide panel 6. The contact of the contact 13 is switched to one of the contacts 14A and 14B. The switching contacts 14A and 14B are connected to the lift drive circuits 11 and 12, respectively, and the movable contact 13 is always connected to the lift switch circuit 3 regardless of the slide position of the slide panel 6. Therefore, the lift switch circuit 3 is connected to the front seat side lift drive circuit 11 when the slide panel 6 is in the forward position, and is connected to the rear seat side lift drive circuit 12 when it is in the retracted position.

  A guide recess 5a deeper than other portions of the recess 5 is formed on the front edge side of the upper surface of the unit case 4 so that the driver can easily place a finger on the tip of the operation knobs 8 and 9.

In the above configuration, for example, when the window glass on the right side of the front seat is moved up and down, the slide panel 6 is displaced to the front slide position as shown in FIG. 3, and the operation knob 9 is operated in that state. At this time, since the movable contact 13 of the contact switching mechanism 10 is in contact with the front switching contact 14A, the lift switch circuit 3 is connected to the front lift drive circuit 11, and as a result, only the windshield on the front seat side is connected. It is operated by the operation knob 9.
On the other hand, the rear elevation drive circuit 12 is not connected to the elevation switch circuit 3 at this time, and therefore cannot be operated unless the slide panel 6 is slid.

  When the window glass on the right side of the rear seat is moved up and down, the slide panel 6 is slid to the rear slide position as shown in FIG. 4, and the operation knob 9 is operated in that state. As a result, the movable contact 13 of the contact switching mechanism 10 contacts the rear switching contact 14B, and the lift switch circuit 3 is connected to the rear lift drive circuit 12. As a result, only the window glass on the rear seat side can be operated by the operation knob 9, and the operation of the window glass on the front seat side is limited.

  The window switch unit 1 is provided with operation knobs 8 and 9 for raising and lowering operations on the slite panel 6 for operating the contact switching mechanism 10, so that the arrangement space for the operation parts on the unit case 4 can be made compact. Therefore, the entire unit can be downsized. Therefore, when this window switch unit 1 is employed, the area occupied by the window switch unit 1 can be reduced, and the degree of freedom of component layout in the vehicle interior can be increased.

  Further, in the window switch unit 1, the front / rear drive circuit 11 or 12 can be completely disengaged from the operation knobs 8 and 9 by sliding the slide panel 6. It is possible to prevent an erroneous operation of operating the window glass by mistake.

  Furthermore, in the case of this window switch unit 1, the operation of the lifting drive circuit 11 or 12 on the unused side can be limited only by providing the contact switching mechanism 10 between the slide panel 6 and the unit case 4. The number of parts such as the operation knobs 8 and 9 can be reduced, which is further advantageous for downsizing the unit.

Next, the first embodiment shown in FIGS. 5 and 6 will be described. In addition, in embodiment described below also including 2nd Embodiment, the same code | symbol shall be attached | subjected to the same part as a reference example, and the overlapping description shall be abbreviate | omitted.

  In the window switch unit 101, a slide panel 106 is slidably operated back and forth on the concave portion 5 of the unit case 4, and an operation knob 9A for a front seat side vehicle window and a rear seat are arranged on the slide panel 106 in the front and rear positions. An operation knob 9B for the side vehicle window is arranged in parallel. Although the front and rear operation knobs 9A and 9B are not shown in the figure, those having the same configuration are provided in two rows in the width direction corresponding to the left and right vehicle windows. Hereinafter, only the right operation knobs 9A and 9B and the mechanisms and circuits associated therewith will be described.

  The front and rear operation knobs 9A and 9B are connected to the individual lift switch circuits 3A and 3B via the lift operation mechanisms 2A and 2B. It is connected. Therefore, in the case of this embodiment, the operation knobs 9A, 9B, the elevation operation mechanisms 2A, 2B and the elevation switch circuits 3A, 3B linked to the operation knobs 9A, 9B are dedicated to the front and rear vehicle windows.

  On the other hand, a limiting wall 20 that extends forward so as to have a set gap with respect to the bottom wall of the recess 5 is integrally formed at the rear edge of the upper surface side of the unit case 4. The rear edge portion of the slide panel 106 is disposed between the recess 5 and the restriction wall 20, and the restriction wall 20 is formed on the rear seat side when the slide panel 106 is slid backward as shown in FIG. The upper side of the operation knob 9B is almost completely covered. Therefore, when the slide panel 106 is in this operation position, the operation of the operation knob 9 is physically restricted by the restriction wall 20.

Since the window switch unit 101 has a structure in which the operation knobs 9A and 9B are arranged on the slide panel 106, the arrangement space of the operation parts on the unit case 4 is made compact as in the reference example, and the entire unit is arranged. Can be miniaturized.

  Further, when the slide panel 106 is slid rearward, the operation of the operation knob 9 </ b> B by the restriction wall 20 can be prevented from being erroneously operated. .

  Further, in the case of this embodiment, since a complicated mechanism such as a contact switching mechanism is not used, the manufacturing cost can be reduced by simplifying the structure.

Next, a second embodiment shown in FIGS. 7 and 8 will be described.
The window switch unit 201 is basically the same as that of the first embodiment except that the window switch unit 201 is turned off when the slide panel 106 is slid forward. The difference is that an operation circuit 25 is provided.

  That is, the shut-off operation circuit 25 includes a position detection sensor 26 that detects that the slide panel 106 is in the forward slide position, and a shut-off switch 27 that receives the detection signal from the position detection sensor 26 and shuts the lift switch circuit 3A. It consists of and.

  Therefore, the window switch unit 201 has the lift switch circuits 3A and 3B (lift drive) on the side that is not operated by the functions of the shutoff operation circuit 25 and the restriction wall 20 when the slide panel 106 is in any of the front and rear slide positions. The operation of the circuits 11, 12) can be reliably restricted.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary. For example, in the above embodiment, the slide member on which the operation knob 9 (9A, 9B) is arranged is configured by the slide panel 6 (106) that is a plate-like member, but the slide member has a shape other than the plate-like shape. Even so, it can be adopted.
