Description

  The present invention relates to a positioning structure, and more particularly to a positioning structure for relatively positioning a first part and a second part.

  Conventionally, a technique for joining a duct for an air conditioner to the back surface of a vehicle ceiling material is generally known (see, for example, Patent Document 1). As a positioning structure of the duct with respect to the vehicle ceiling material, for example, as shown in FIG. 7A, a first mark 111 for positioning is provided on the upper surface of the duct 102 having a large height, and the rear surface of the vehicle ceiling material 103 is provided. One having a second mark 112 for positioning thereon is known. Then, when joining the duct 102 to the vehicle ceiling material 103, the duct 102 is positioned with respect to the vehicle ceiling material 103 by combining the first mark 111 and the second mark 112. Note that the component 117 (for example, felt, wire harness, etc.) having a small height dimension is located at a position corresponding to the corner of the component 117 on the back surface of the vehicle ceiling material 103, as shown in FIG. 7B, for example. By providing a positioning mark 113 having a substantially L-shaped plane and aligning the corner of the part 117 with the mark 113, the part 117 is positioned with respect to the vehicle ceiling material 103.

The gist of the invention described in claim 3 is that, in the invention described in claim 1 or 2, the first mark further continues to the lower surface of the first part.
The invention according to claim 4 is the invention according to any one of claims 1 to 3, wherein the first part is a duct for vehicle air conditioning, and the second part is the duct on the back surface thereof. Is a vehicle ceiling material to be joined.

According to the positioning structure of the present invention, the first component has a three-dimensional shape, and the second component has at least one plane to which the lower surface of the first component is joined. A first mark for positioning extending linearly from the lower end of the side surface is provided, and a second mark for positioning formed by intersecting two or more lines is provided on the plane of the second component. It has been. And when joining a 1st component and a 2nd component, a 1st component and a 2nd component are relatively positioned by match | combining a 1st mark and a 2nd mark. Thereby, the operator can match | combine a 1st mark and a 2nd mark correctly by using the lower part of a 1st mark as a mark by seeing a 1st component from diagonally side. Therefore, even a component having a large height can be easily and accurately positioned.
Further, the first mark is formed when the second mark is formed by combining the intersecting portion where the two or more lines intersect with the intersecting portion extending from the intersecting portion and the first mark and the second mark. And an extension portion located below the lower surface of the component, the operator uses the extension portion of the second mark as well as the lower portion of the first mark as a mark, so that the intersection of the first mark and the second mark Can be adjusted more accurately.
Further, when the first mark is further continued to the lower surface of the first component, the visibility of the first mark is further enhanced.

This is a structure for relatively positioning the material 3 (illustrated as “second part” according to the present invention). This positioning structure 1A is a structure for positioning the duct 2 with respect to a predetermined direction of the vehicle ceiling material 3 (for example, the vehicle longitudinal direction). The positioning structure 1 </ b> B is a structure for positioning the duct 2 with respect to a predetermined direction (for example, the vehicle width direction) orthogonal to the predetermined direction of the vehicle ceiling material 3. Since the positioning structures 1A and 1B have substantially the same configuration, the positioning structure 1A will be mainly described in detail below.

  As shown in FIGS. 2 to 4, the duct 2 is formed in a hollow box shape (three-dimensional shape) and has a height direction dimension of about 50 mm. The duct 2 has a side surface and a lower surface connected by a chamfered portion 5 having an arc surface. The vehicle ceiling material 3 is formed in a planar rectangular shape. The vehicle ceiling material 3 has a flat surface 3a (that is, the back surface facing the outside of the passenger compartment when the vehicle ceiling material 3 is mounted on the vehicle) to which the lower surface of the duct 2 is joined via an adhesive layer 6 (see FIG. 4). Yes. Further, the duct is disposed on the plane 3 a of the vehicle ceiling material 3 so as to block the opening 8 (see FIG. 1) formed in the vehicle ceiling material 3.

  The duct 2 is provided with a first positioning mark 11 extending linearly continuously from the upper surface to the lower end of the side surface and further to the lower surface. The first mark 11 is formed in a convex shape protruding from the surface of the duct 2. The protruding height h of the first mark 11 is set to a value that is substantially the same as the thickness of the adhesive layer 6 (for example, about 1 mm) (see FIG. 4). The first mark 11 is formed at the same time as the resin duct 2 is molded. Further, the first marks 11 are arranged in parallel in the horizontal direction with a predetermined interval (for example, about 7 mm). A predetermined interval between the pair of first marks 11 is an allowable range of positioning.

  On the plane 3a of the vehicle ceiling material 3, a second mark 12 for positioning is provided that intersects three straight lines. The second mark 12 is formed in a substantially arrow shape on the plane. The second mark 12 is formed in a concave shape that is recessed from the flat surface 3 a of the vehicle ceiling material 3. The second mark 12 is formed at the same time as the vehicle ceiling member 3 is molded. The second mark 12 includes an intersection 14 where three straight lines intersect and an extension 15 extending from the intersection 14. The extension portion 15 is arranged so as to be positioned below the lower surface of the duct 2 when the intersecting portion 14 of the first mark 11 and the second mark 12 is combined (see FIG. 3).
