Description

  The present invention, for example, unlocks the door lock mechanism by operating an operation member having an operation surface on which the back side of the design surface is placed for operation, such as an inside handle of a vehicle door. The present invention relates to a vehicular operating device that performs switching.

As this type of operation device, for example, an inside handle device disclosed in Patent Document 1 is already known. As is clear from this technique, the inside handle is incorporated inside a bezel fixed to the door inner panel side, and can be rotated by using a hinge shaft supported by the bezel as a fulcrum. By the rotation operation of the handle, the door lock mechanism is unlocked through the cable.
Thus, since the inside handle is a member that is operated in the vehicle, the front surface is a design surface located on the inside of the vehicle, and the back surface is an operation surface on which the occupant places a hand for operation. In addition, the inside handle is generally an integrally molded product made of a resin material and needs to be strong enough to withstand an operation load.
JP 9-317264 A

  As described above, the operation member represented by the inside handle is thick throughout to ensure the strength necessary for operation, and the thickness is uneven, and there are sink marks and the like when molding with a resin material. Likely to happen. However, as described above, the surface of the operation member is a design surface, and the back surface is an operation surface. Therefore, it is impossible to set a thin-walled concave portion to avoid sink marks on the operation member. There remains a problem that the operation member is lowered or the weight of the operation member is large.

  The present invention is intended to solve such problems, and its purpose is to maintain the design surface or the operation surface of the operation member properly as before and also maintain the strength required for the operation member. This is to prevent the occurrence of sink marks and to reduce the weight of the operation member itself.

The present invention is for achieving the above object, and is configured as follows.
1st invention is the operating device for vehicles which changes a predetermined mechanism by operation of the operation member used as the operation surface which the back side of a design surface puts on for operation, and an operation member is required for operation A base material having a sufficient strength and a cover material separate from the base material. And at least the base material is integrally formed of a resin material, and the cover material is put on the base material so as to constitute either the design surface or the operation surface of the operation member. In the surface of the base material covered with the cover material, a thinned recess is set.

  Thereby, the design surface or the operation surface of the operation member can be properly maintained as before, and the thickness of the substrate can be made thin and uniform while maintaining the strength required for the operation member. For this reason, generation | occurrence | production of sink etc. when a base material is shape | molded with a resin material is prevented, and weight reduction of operation member itself can be achieved.

In a second aspect based on the first aspect, the cover material is placed on the base material so as to constitute the design surface of the operation member.
In this configuration, it is possible to diversify the design surface of the operation member simply by selecting the cover material, and the variation of the design surface can be easily increased. In addition, since the object to be processed on the design surface is only a small piece cover material, the manufacturing cost of the operation member can be reduced.

In a third aspect based on the first aspect, the cover material is placed on the base material so as to constitute the operation surface of the operation member.
In this configuration, the feel when the operation surface of the operation member is touched by the hand can be changed by selecting the material of the cover material and the surface processing.

Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.
In FIG. 1 showing an inside handle of a vehicle door, an arrow F indicates a front direction of the vehicle, an arrow R indicates a rear direction of the vehicle, and an arrow I indicates an in-vehicle direction. The handle 10 that is an operation member can be rotated in the in-vehicle direction at the front end with the support axis 16 on the rear side as a fulcrum. By this operation, the door lock mechanism is unlocked through a cable (not shown). The handle 10 is housed inside a bezel (not shown) fixed to the door inner panel, and both ends of a hinge shaft (not shown) disposed on the support axis 16 are supported by the bezel.

Although the handle | steering-wheel 10 shows the type of the frame shape in which the center part was open | released, it is not limited to this shape. And the front side which faced the inside of the handle | steering-wheel 10 is the design surface 12, and the back side is the operation surface 14. The operation surface 14 is a surface on which an occupant places a hand when rotating the handle 10 as described above.
Further, the handle 10 includes a base material 20 that constitutes a main part thereof, and a cover material 30 that constitutes the design surface 12 of the handle 10 separately from the base material 20. As a matter of course, the base material 20 and the cover material 30 have a frame shape.

First, the base material 20 will be described with reference to FIGS. The base material 20 is an integrally molded product made of a resin material (ABS or the like), and is set to a thickness that ensures the strength necessary for the operation of the handle 10. The front side (FIG. 2) of the base material 20 is a surface covered with the cover material 40, and the portion closer to the front on the back side (FIG. 5) becomes the operation surface 14 of the handle 10.
A hole-shaped bearing portion 22 penetrating vertically along the above-described support axis 16 is provided at the rear side end portion of the base material 20, and a hinge shaft is inserted into the bearing portion 22 so that the base material 20 is attached. Supported by the bezel. On the back side of the base material 20 is provided an arm portion 24 that protrudes from the vicinity of the bearing portion 22 toward the inside of the door, and the end portion of the arm portion 24 has a bottomed hole shape that joins the end portion of the cable described above. The connecting portion 26 is formed (FIGS. 3 to 5).

As described above, since the base material 20 is set to have a thickness that ensures a predetermined strength, a thick portion partially exists. In order to eliminate such uneven thickness, a thickened recess 28 is set on the front side of the base material 20 covered with the cover material 30 (FIG. 2). The meat thinning recess 28 shown in the drawing is set at two locations on the base material 20. However, since the number and shape of the thin-walled concave portions 28 are determined for the purpose of making the thickness of the base material 20 uniform, there are various patterns other than the illustrated one.
The base material 20 is provided with holes, claws and the like for coupling with the cover material 30, and the specific structure thereof will be described later in relation to the cover material 30.

  The cover material 30 will be described with reference to FIGS. 6 to 9. The cover material 30 is also an integrally molded product made of a resin material (ABS or the like). However, since the cover material 30 does not require the strength as the base material 20, it is set to be thin as a whole. The front side (FIG. 6) of the cover member 30 is a surface constituting the design surface 12 of the handle 10 and is subjected to a finishing process such as plating. Further, the back side (FIG. 9) of the cover material 30 is a surface joined to the front side of the base material 20.

Next, a coupling structure between the base material 20 and the cover material 30 will be described with reference to FIGS. 10 to 12 show cross sections of the respective parts in FIG. 2 in a state where the cover material 30 is virtually covered on the base material 20.
As is clear from FIG. 10 showing the cross section in the direction of the arrow AA in FIG. 2, the dowel 30 a on the back side of the cover material 30 is fitted in the dowel hole 20 a on the front side of the base material 20. This is a base point for positioning 20 and the cover material 30. Further, the engaging claw 20b at the rear side end of the base material 20 is engaged with the engaging hole 30b of the cover material 30, and the cover material is inserted into the engaging hole 20c at the front side end of the base material 20. 30 engagement claws 30c are engaged.
When covering the base material 20 with the cover material 30, the engagement claw 30 c of the cover material 30 is first inserted into the engagement hole 20 c of the base material 20, and then the cover material 30 is joined to the base material 20. The engagement hole 30b is engaged with the joint claw 20b, and the dowel 30a is fitted into the dowel hole 20a.

As is clear from FIG. 11 showing the cross section in the direction of the arrow BB in FIG. 2, the grip portion 30 d of the cover member 30 is engaged with the notch portion 20 d at the upper edge of the open portion of the base material 20. The engaging claw 30e of the cover member 30 is engaged with the engaging hole 20e in the lower part of the base member 20. Further, as is apparent from FIG. 12 showing the cross section in the direction of the CC arrow in FIG. 2, the engaging claw 30f of the cover member 30 is engaged with the engaging groove 20f at the lower edge of the open portion of the base member 20. Match.
These coupling means shown in FIGS. 11 and 12 are engaged almost simultaneously when the cover member 30 is joined to the base member 20 as described above.

By covering the front surface of the base material 20 with the cover structure 30 as described above, as shown in FIG. 13 showing the cross section in the direction of the arrow DD in FIG. 12 and FIG. The recess 28 is covered with a cover material 30. The design surface 12 of the handle 10 is maintained in a good-looking state by the cover material 30.
And about the base material 20, thickness can be made thin and uniform, maintaining the intensity | strength requested | required of the handle | steering-wheel 10 by the thinly-filled recessed part 28. FIG. Accordingly, when the base material 20 is molded with resin, sink marks or the like can be prevented from occurring on the back side of the handle 10 as the operation surface 14, and the handle 10 can be reduced in weight.

  Furthermore, since the design surface 12 of the handle 10 is constituted by the cover material 30, only the cover material 30 needs to be plated or the like to decorate the design surface 12, and the manufacturing cost of the handle 10 can be reduced. Moreover, the variation of the design surface 12 in the handle | steering-wheel 10 can be increased by selecting and covering the cover material 30 of another kind from which the design of the front side differs with respect to the kind of base material 20 with the cost suppressed.

As shown in FIG. 14, it is also possible to set a thin-walled concave portion 29 on the back side of the base material 20 and cover the back side with the cover material 40 shown in FIG. 15. In this case, the design surface 12 of the handle 10 is constituted by the front side of the base material 20, and the operation surface 14 of the handle 10 is constituted by the cover material 40. Therefore, by making the cover material 40 a soft material, or by applying a texture or the like to the front side of the cover material 40, it is possible to change the feel when the operation surface 14 of the handle 10 is touched by hand.
In the above, the inside handle of the vehicle door has been described as the operation member. However, the present invention can also be applied to an operation member such as a walk-in lever provided on the back of the seat back or the shoulder of the vehicle seat. .
