Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, conventional exterior parts for vehicles such as a back door finisher are not integrally provided with positioning pins for positioning with respect to a vehicle body panel such as a back door panel before being fastened to the vehicle body panel with bolts or the like. For this reason, when positioning with respect to a vehicle body panel is required, a positioning pin formed separately from the exterior part for the vehicle is attached to the exterior part for the vehicle. By inserting such a positioning pin into a grommet or the like provided on the vehicle body panel, the exterior part for the vehicle is positioned with respect to the vehicle body panel. Then, the positioned exterior part for the vehicle is fastened to the vehicle body panel, whereby the exterior part for the vehicle is fixed with respect to the vehicle body panel.
[0005] However, as described above, when the positioning pin is formed separately from the exterior part for the vehicle, an operation of attaching the positioning pin to the exterior part for the vehicle is required. Such an attaching operation needs to be performed by an operator, which increases the work load of the operator.
[0006] This invention has been made in view of the above-mentioned problems, and aims to eliminate the need for the installation of a separately formed positioning pin in an exterior vehicle part that is positioned relative to a vehicle body panel. [Means for solving the problem]
[0007] The present invention employs the following configuration as a means to solve the above problems.
[0008] A first aspect of the present invention is a vehicle exterior component fixed to a vehicle body panel, comprising a design wall having a design surface on at least a part of its outer wall surface, and a positioning portion formed integrally with the design wall on the inner wall surface of the design wall, wherein the positioning portion comprises a base portion integrally connected to the design wall, and an insertion projection integrally connected to the base portion and protruding from the base portion toward the vehicle body panel, and being inserted into an insertion portion provided in the vehicle body panel.
[0009] A second aspect of the present invention is a configuration in which, in the first aspect, the positioning portion is erected on the mounting surface to which the insertion projection of the base portion is connected and has a rib connected to the insertion projection.
[0010] A third aspect of the present invention is the second aspect described above, wherein the positioning portion has four ribs, and when viewed from a direction along the axis of the insertion projection, the four ribs are arranged at equal intervals in the circumferential direction centered on the axis.
[0011] A fourth aspect of the present invention adopts a configuration in which, in the second or third aspect described above, there is a fillet portion that connects the circumferential surface of the insertion projection and the mounting surface of the base portion. [Effects of the Invention]
[0012] In the present invention, a positioning portion having a base portion and an insertion projection portion is integrally formed on the inner wall surface of the design wall. Therefore, by inserting the insertion projection portion of the positioning portion into a grommet or the like provided on the vehicle body panel, it becomes possible to position the vehicle exterior component relative to the vehicle body panel. Accordingly, according to the present invention, it becomes possible to eliminate the need to attach a separately formed positioning pin to a vehicle exterior component that is positioned relative to a vehicle body panel.

[Modes for carrying out the invention]
[0014] Hereinafter, an embodiment of a vehicle exterior part according to the present invention will be described with reference to the drawings. In the following description, an example will be given in which the vehicle exterior part of the present invention is applied to a back door finisher provided on the back door of a vehicle. However, the present invention is not limited thereto.
[0015] FIG. 1 is a schematic view of a vehicle 100 including a back door finisher 1 (exterior component for a vehicle) of the present embodiment as seen from the rear. As shown in this FIG., the back door finisher 1 of the present embodiment is an exterior component arranged at the rear part of the vehicle. A back door panel 101 (body panel) that can be opened and closed is provided at the rear part of the vehicle 100, and the back door finisher 1 of the present embodiment is fixed to the back door panel 101.
[0016] FIG. 2 is a schematic perspective view of the back door finisher 1 of the present embodiment as seen from the back side. Further, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2. As shown in these FIGS., the back door finisher 1 of the present embodiment includes a finisher main body part 2 and a rubber member 3.
[0017] The finisher main body part 2 is integrally formed by injection molding of resin, and as shown in FIGS. 2 and 3, has a design wall 2a, an upper edge wall 2b, a lower edge wall 2c, a positioning part 2d, and a mounting part 2e. In the following description, the space surrounded by the design wall 2a, the upper edge wall 2b, and the lower edge wall 2c is taken as the inside of the finisher main body part 2.
[0018] The design wall 2a is a part where the outer wall surface 2a1 is a design surface visible from the outside, and the outer wall surface 2a1 is fixed in a posture facing the rear of the vehicle 100 at a part excluding the upper end part 2a2 and the lower end part 2a3. The design wall 2a is formed in a long shape extending in the vehicle width direction of the vehicle 100. Further, the upper end part 2a2 and the lower end part 2a3 of the design wall 2a are bent toward the back door panel 101. As shown in FIG. 2, a single positioning part 2d and a plurality of mounting parts 2e are provided on the inner wall surface 2a4 of the design wall 2a.
[0019] The upper edge wall 2b is a part protruding from the upper end part 2a2 of the design wall 2a toward the back door panel 101 (that is, the front of the vehicle 100). In the present embodiment, the upper edge wall 2b protrudes in the horizontal direction and extends along the vehicle width direction (the direction in which the design wall 2a extends), which is a direction intersecting the protruding direction (the front-rear direction of the vehicle 100).
[0020] The lower edge wall 2c is a portion that protrudes from the lower end portion 2a3 of the design wall 2a in the direction of the back door panel 101 (i.e., the front of the vehicle 100). In the present embodiment, the lower edge wall 2c protrudes in the horizontal direction and extends along the vehicle width direction (the direction in which the design wall 2a extends), which is a direction intersecting the protruding direction (the longitudinal direction of the vehicle 100).
[0021] As shown in FIG. 2, the positioning portion 2d is provided on the inner wall surface 2a4 of the design wall 2a and has an insertion protrusion portion 2d2 that protrudes toward the back door panel 101, which will be described later. This positioning portion 2d is a portion for aligning the position of the back door finisher 1 with respect to the back door panel 101 when the back door finisher 1 of the present embodiment is attached to the back door panel 101. Before fastening the back door finisher 1 to the back door panel 101 with bolts (not shown), as shown in FIG. 3, by inserting the insertion protrusion portion 2d2 of the positioning portion 2d into a grommet G (insertion portion) attached to the back door panel 101, the position of the back door finisher 1 with respect to the back door panel 101 is determined.
[0022] FIG. 4 is an enlarged perspective view of the positioning portion 2d. Further, FIG. 5 is a schematic enlarged cross-sectional view of the positioning portion 2d and is a cross-sectional view taken along line B-B of FIG. 4. As shown in these figures, the positioning portion 2d has a base portion 2d1, an insertion protrusion portion 2d2, a rib 2d3, and a fillet portion 2d4.
[0023] The base portion 2d1 is provided, for example, as shown in FIG. 2, so as to protrude from the inner wall surface 2a4 of the design wall 2a in the normal direction of the inner wall surface 2a4. This base portion 2d1 is integrated with the inner wall surface 2a4 of the design wall 2a, has no boundary surface, and is connected to the inner wall surface 2a4 of the design wall 2a. Further, the front end surface 2d5 of the base portion 2d1 is flat and is used as an installation surface for the insertion protrusion portion 2d2, the rib 2d3, and the fillet portion 2d4. For example, as shown in FIGS. 4 and 5, the base portion 2d1 is formed in a hollow shape with a space provided inside and an opening provided on the side portion.
[0024] The insertion projection 2d2 is integrally connected to the base portion 2d1 and protrudes from the front end surface 2d5 of the base portion 2d1 toward the back door panel 101. The insertion projection 2d2 has a base portion 2d6 connected to the base portion 2d1, a tip portion 2d7 that decreases in diameter towards the tip, and an intermediate portion 2d8 interposed between the base portion 2d6 and the tip portion 2d7. These base portion 2d6, tip portion 2d7, and intermediate portion 2d8 are arranged concentrically with respect to the axis L of the insertion projection 2d2. The intermediate portion 2d8 has a smaller diameter than the base portion 2d6, and also has a smaller diameter than the portion of the tip portion 2d7 that is on the intermediate portion 2d8 side.
[0025] The rib 2d3 is erected on the tip surface 2d5 of the base portion 2d1 and connected to the insertion projection 2d2. In this embodiment, four ribs 2d3 are provided, as shown in Figure 4, for example. The projection dimensions of each rib 2d3 from the tip surface 2d5 are all the same. The tip surfaces of these ribs 2d3 in the direction of projection from the tip surface 2d5 are used as contact surfaces for the grommet G provided on the back door panel 101.
[0026] Each rib 2d3 is extended in a straight line, and one end in the direction of extension is connected to the circumferential surface of the base portion 2d6 of the insertion projection 2d2. As shown in Figure 5, the rib 2d3 is connected to the insertion projection 2d2 such that the circumferential surface of the base portion 2d6 and the tip surface of the rib 2d3 are at a right angle.
[0027] Furthermore, as shown in Figure 4, the four ribs 2d3 are arranged at equal intervals in the circumferential direction around the axis L of the insertion projection 2d2, when viewed from a direction along the axis L. In other words, the four ribs 2d3 are arranged at 90° intervals in the circumferential direction around the axis L. This arrangement of the four ribs 2d3 results in a plus (+) shape, as shown in Figure 4.
[0028] The fillet portion 2d4 is a part that connects the circumferential surface of the insertion projection 2d2 and the tip surface 2d5 of the base portion 2d1 with a curved surface, and is integrally provided with the insertion projection 2d2 and the base portion 2d1. The fillet portions 2d4 are provided between the ribs 2d3 in the circumferential direction centered on the axis L. In other words, in this embodiment, except for the positions where the ribs 2d3 are formed, the fillet portions 2d4 are provided to connect the circumferential surface of the insertion projection 2d2 and the tip surface 2d5 of the base portion 2d1. These fillet portions 2d4 distribute the stress acting between the insertion projection 2d2 and the base portion 2d1 so as not to concentrate locally when an external force is applied to the insertion projection 2d2 in a direction that tilts the axis L.
[0029] Returning to Figure 2, the mounting portion 2e is the part that is fixed to the back door panel 101 by bolts or clips (not shown). As shown in Figure 2, multiple mounting portions 2e are provided on the inner wall surface 2a4 of the design wall 2a. These mounting portions 2e are arranged in the extending direction of the back door finisher 1 (the extending direction of the design wall 2a, which is the vehicle width direction).
[0030] The rubber member 3 is a cushioning member attached to the upper edge wall 2b and the lower edge wall 2c via an adhesive sheet. The rubber member 3 is interposed between the finisher body 2 and the back door panel 101 to prevent contact between the finisher body 2 and the back door panel 101. Such rubber members 3 are made of a soft resin and multiple rubber members are attached to each of the upper edge wall 2b and the lower edge wall 2c.
[0031] When attaching the back door finisher 1 of this embodiment to the back door panel 101, for example, with a clip attached to one of the mounting parts 2e slidably locked to the back door panel 101, the insertion projection 2d2 of the positioning part 2d is inserted into the grommet G provided on the back door panel 101.
[0032] By inserting the insertion projection 2d2 into the grommet G in this manner, the back door finisher 1 of this embodiment is positioned relative to the back door panel 101. Subsequently, the mounting portion 2e, which does not have a clip, is fastened to the back door panel 101 with bolts (not shown). This fixes the back door finisher 1 of this embodiment to the back door panel 101.
[0033] The back door finisher 1 of this embodiment, as described above, is fixed to the back door panel 101. The back door finisher 1 of this embodiment also has a decorative wall 2a having a decorative surface on at least a part of the outer wall surface 2a1, and a positioning portion 2d formed integrally with the decorative wall 2a on the inner wall surface 2a4 of the decorative wall 2a. Furthermore, the positioning portion 2d has a base portion 2d1 integrally connected to the decorative wall 2a, and an insertion projection 2d2 integrally connected to the base portion 2d1 and protruding from the base portion 2d1 toward the back door panel 101, and inserted into a grommet G provided on the back door panel 101.
[0034] In this embodiment of the back door finisher 1, a positioning portion 2d having a base portion 2d1 and an insertion projection 2d2 is integrally formed on the inner wall surface 2a4 of the design wall 2a. Therefore, by inserting the insertion projection 2d2 of the positioning portion 2d into a grommet G provided on the back door panel 101, the back door finisher 1 can be positioned relative to the back door panel 101. Accordingly, according to the present invention, in a back door finisher 1 that is positioned relative to the back door panel 101, it is possible to eliminate the need to attach a separately formed positioning pin.
[0035] Furthermore, in the back door finisher 1 of this embodiment, the positioning part 2d is erected on the installation surface (tip surface 2d5) to which the insertion projection 2d2 of the base part 2d1 is connected, and has a rib 2d3 connected to the insertion projection 2d2. With the back door finisher 1 of this embodiment, the grommet G is restricted by contact with the rib 2d3, so the grommet G does not come into contact with the installation surface of the insertion projection 2d2. In the back door finisher 1 of this embodiment, by matching the shape of the connection point between the rib 2d3 and the insertion projection 2d2 to the shape of the grommet G, the grommet G and the back door finisher 1 can be made to make stable surface contact. Therefore, it is not necessary to match the shape of the connection point between the base part 2d1 and the insertion projection 2d2 to the shape of the grommet G. Therefore, with the back door finisher 1 of this embodiment, it is only necessary to match the shape of the portion where the rib 2d3 is provided in the circumferential direction centered on the axis L of the insertion projection 2d2 to the shape of the grommet G, and it is not necessary to match the shape of the portion where the rib 2d3 is not provided in the same circumferential direction to the shape of the grommet G. Thus, with the back door finisher 1 of this embodiment, it is only necessary to match the shape of the grommet G to a portion of the circumferential direction centered on the axis L of the insertion projection 2d2, thereby improving the degree of freedom of the shape of the finisher body 2.
[0036] Furthermore, in the back door finisher 1 of this embodiment, the positioning portion 2d has four ribs 2d3, and when viewed from a direction along the axis L of the insertion projection 2d2, the four ribs 2d3 are arranged at equal intervals in the circumferential direction centered on the axis L. As described above, in the back door finisher 1 of this embodiment, the four ribs 2d3 are arranged at 90° intervals in the circumferential direction centered on the axis L, and are arranged in a + (plus) shape. Figure 6 is a schematic diagram showing slide cores S1 and slide cores S2 when the positioning portion 2d is formed by injection molding. For example, as shown in Figure 6, it is possible to form the positioning portion 2d with two slide cores S1 and slide core S2. By moving these slide cores S1 along two of the four ribs 2d3 that are arranged in a straight line, it is possible to move the slide cores S1 without interfering with a part of the positioning portion 2d.
[0037] Furthermore, the back door finisher 1 of this embodiment has a fillet portion 2d4 that connects the circumferential surface of the insertion projection 2d2 and the mounting surface of the base portion 2d1. Such a fillet portion 2d4 distributes the stress acting between the insertion projection 2d2 and the base portion 2d1 so as not to concentrate locally when an external force is applied to the insertion projection 2d2 in a direction that causes the axis L to tilt. Therefore, the back door finisher 1 of this embodiment makes it possible to prevent cracks from occurring at the base of the insertion projection 2d2 due to external forces when attaching it to the back door panel 101, etc.
[0038] Preferred embodiments of the present invention have been described above with reference to the attached drawings, but it goes without saying that the present invention is not limited to the above embodiments. The shapes and combinations of the constituent members shown in the above embodiments are examples, and can be modified in various ways based on design requirements, etc., without departing from the spirit of the present invention.
[0039] For example, in the above embodiment, a configuration in which the vehicle exterior component of the present invention is a back door finisher 1 was described. However, the present invention is not limited thereto. For example, the present invention can also be applied to a front bumper finisher or a door side molding.
[0040] Furthermore, the above embodiment describes a configuration in which the insertion projection 2d2 is inserted into the grommet G. However, the present invention is not limited thereto. For example, an insertion hole or other insertion part may be directly formed in the back door panel 101, and the insertion projection 2d2 may be inserted into that insertion part.
