Description

  The present invention relates to a resin component mounting and fixing structure.

  Conventionally, a technique for attaching a spoiler to the lower edge of a front bumper cover is already known from the viewpoint of improving the aerodynamic performance of the vehicle. Here, the following patent document 1 discloses a technique for mounting using various resin clips or metal bolts. Thereby, a spoiler can be attached with a simple structure.

As prior art document information related to the invention of this application, for example, Patent Document 1 is known.
JP 2000-264261 A

  However, in the above-described prior art, the attached spoiler may be rattled due to rattling caused by the resin clip. In order to solve this problem, a spoiler is sometimes attached using a bolt. However, when metal bolts are used, when the front bumper cover and spoiler are removed from the vehicle body as the vehicle is recycled, the metal bolts must be separated from the front bumper cover and spoiler. For this reason, when recycling, it takes time and labor for sorting.

  The present invention is intended to solve such problems, and its purpose is to provide a resin component mounting and fixing structure that does not cause backlash in the mounted state and does not require separation even when recycled. Is to provide.

The present invention is for achieving the above object, and is configured as follows. The invention according to claim 1 is a structure in which the resin component is attached to the attached member, and the attached member has a flange portion, and the flange portion has an insertion hole and a hook portion. The resin part has an edge that faces the flange of the mounted member, and the edge has an engagement hole that faces the insertion hole of the flange, and an engagement claw that uses a hinge The resin part is temporarily fixed to the mounted member by inserting the edge part into the hook part while abutting the flange part and the edge part. Further, the insertion hole and the opening part of the engagement hole substantially coincide with each other. Then, the engaging claw diffracts the hinge and passes through the insertion hole, and then engages with the engaging hole.
According to this structure, unlike the case where the resin component is attached using the resin clip, there is no backlash in the attached state of the resin component. Moreover, since the metal bolt is not used, for example, even when the resin part is removed from the attached member due to recycling, it is not necessary to separate the metal bolt from the attached member and the resin part.

The invention according to claim 2 is the resin component mounting and fixing structure according to claim 1, wherein an engagement reinforcing piece is installed in the engagement hole. .
According to this structure, it is possible to stop loosening and vibration of the engaging claws in the attached state of the resin component, and further suppress the occurrence of rattling.

FIG. 2 is a plan view of the spoiler in FIG. 3 is a cross-sectional view taken along line III-III of FIG. 2 in the assembled state of FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. 2, showing a process of attaching a spoiler from the state of FIG. FIG. 5 shows a state during the attachment of FIG. FIG. 6 shows a state where the attachment of FIG. 5 is completed.

  Hereinafter, the form for implementing this invention is demonstrated using FIGS. In the following description, the front bumper cover 10 and the spoiler 20 of the vehicle 1 will be described as examples of the mounted member and the resin component. In the following description, “up”, “down”, “front”, “back”, “left”, and “right” refer to the directions of “up”, “down”, “front”, “back”, “left”, and “right” described in the above-described drawings. When up, down, front, back, left, right direction is shown. In addition, it cannot be overemphasized that the up-down direction, the front-back direction, and the left-right direction which are said here have mutually orthogonal relationship.

  First, with reference to FIGS. 1-4, the front bumper cover 10 and the spoiler 20 which concern on the Example of this invention are demonstrated separately.

  First, the front bumper cover 10 will be described with reference to FIGS. The front bumper cover 10 is a resin cover member formed so as to cover the lower side of the front of the vehicle body. For example, the design of the vehicle 1 can be improved by the front bumper cover 10. A flange portion 12 is formed at the lower edge of the front bumper cover 10 toward the inside of the vehicle 1 along the longitudinal direction thereof. The front end of the flange portion 12 is formed in a hook shape at appropriate locations in the longitudinal direction (for example, locations corresponding to both sides of the mounting portion 14 described later) (hereinafter referred to as “hook portion 12a”). ).

  Further, an attachment portion 14 is formed at an appropriate position in the longitudinal direction of the flange portion 12 so as to extend its tip. In this example, six attachment portions 14 are formed. The attachment portion 14 is formed with an insertion hole 14a penetrating in the thickness direction. The front bumper cover 10 is integrally formed with a synthetic resin having rigidity together with the flange portion 12 and the mounting portion 14.

  Next, the spoiler 20 will be described with reference to FIGS. The spoiler 20 is a resin cover member formed so as to cover the lower side of the front bumper cover 10 described above. For example, the aerodynamic performance of the vehicle 1 can be improved by the spoiler 20. An edge 22 is formed on the upper edge of the spoiler 20 toward the inside of the vehicle 1 along its longitudinal direction. The edge portion 22 can be engaged with the hook portion 12a described above. This description corresponds to “inserting the edge portion into the hook portion” described in the claims.

  Further, seal members 40, 40 are fixed to both surfaces (upper and lower surfaces) of the edge portion 22, respectively. As a result, as described above, even when the edge portion 22 and the hook portion 12a are engaged with each other, it is possible to prevent rattling caused by this engagement. Further, the seal members 40, 40 may be fixed not to the edge portion 22 but to the flange portion 12 or the hook portion 12a side, as long as the seal members 40, 40 can prevent rattling without any trouble.

  Further, a mounting portion 24 is formed at a location facing the mounting portion 14 described above in the edge portion 22. Therefore, in this example, six attachment portions 24 are also formed. The attachment portion 24 is formed with an engagement hole 24a penetrating in the thickness direction so as to face the insertion hole 14a described above. On the inner inner wall surface (the inner wall surface of the inner wall surface located inside the vehicle 1) 24b, an engagement reinforcing piece 30 is extended from the surface. This description corresponds to “the engagement reinforcing piece is provided in the engagement hole” described in the claims.

  Further, an engaging claw 26 is formed on the edge on the front end side of the mounting portion 24 via a hinge 28. The engaging claw 26 has a configuration including a bending piece 26b having a protrusion 26a on the tip side. Therefore, when the engagement claw 26 is rotated upward around the axis of the hinge 28, the protrusion 26a can be engaged with the edge of the engagement hole 24a through the insertion hole 14a. This will be described in detail later. The spoiler 20 is also integrally formed with a rigid synthetic resin together with the edge portion 22, the attachment portion 24 and the engaging claw 26.

  Next, a procedure for attaching the spoiler 20 to the above-described front bumper cover 10 will be described with reference to FIGS. First, from the state shown in FIG. 1, the operation of engaging the hook portion 12a of the flange portion 12 of the front bumper cover 10 and the edge portion 22 of the spoiler 20 is performed (see FIG. 3).

  When engaged in this manner, the spoiler 20 is in a state where movement in the vertical direction with respect to the front bumper cover 10 is restricted. At this time, the above-described engagement operation is performed so that the insertion holes 14a and the engagement holes 24a of both the attachment portions 14 and 24 are aligned (see FIG. 4). This engagement operation is performed in all the attachment portions 14 and 24.

  Next, an operation of rotating the engagement claw 26 of the spoiler 20 upward around the axis of the hinge 28 is performed. Then, the bending piece 26 b of the engaging claw 26 is inserted into the engaging hole 24 a of the spoiler 20 through the insertion hole 14 a of the front bumper cover 10.

  At this time, the protrusions 26a of the engaging claws 26 are pressed against the outer inner wall surfaces (the inner wall surfaces of the inner wall surfaces located outside the vehicle 1) 14c, 24c of the holes 14a, 24a. The bending piece 26b begins to bend toward the inside of the vehicle 1 (rearward direction in FIG. 5) (see FIG. 5). Eventually, when the projection 26a of the engaging claw 26 gets over the outer inner wall surfaces 14c, 24c of the holes 14a, 24a, the bending piece 26b of the engaging claw 26 is returned by the reaction force of the bending. The protrusion 26a is engaged with the edge of the engagement hole 24a of the spoiler 20 (see FIG. 6).

  At the time of this engagement, the bending piece 26b of the engaging claw 26 presses the engagement reinforcing piece 30, so that the bending piece 26b is brought into contact with the outer inner wall surfaces 14c and 24c of the holes 14a and 24a by the reaction force of the pressing. Each is pressed. When pressed in this manner, the spoiler 20 is in a state in which movement in the front-rear direction is restricted with respect to the front bumper cover 10. This rotating operation is performed for all the engaging claws 26. In this way, the spoiler 20 is attached to the front bumper cover 10.

  The attachment fixing structure of the spoiler 20 according to the embodiment of the present invention is configured as described above. According to this configuration, unlike the case where the spoiler 20 is attached using a resin clip, no rattling occurs in the attached state of the spoiler 20. Further, since metal bolts are not used, it is not necessary to separate the metal bolts from the front bumper cover 10 and the spoiler 20 even when the front bumper cover 10 and the spoiler 20 are removed from the vehicle body as the vehicle 1 is recycled.

  Further, according to this configuration, the engagement reinforcing piece 30 is extended from the inner inner wall surface 24b of the engagement hole 24a. Therefore, loosening and vibration of the engaging claws in the attached state of the spoiler 20 can be stopped, and rattling can be further suppressed.

The contents described above are only related to one embodiment of the present invention, and do not mean that the present invention is limited to the above contents.
In the embodiment, the front bumper cover 10 and the spoiler 20 of the vehicle 1 have been described as examples of the resin mounted member and the resin component. However, the present invention is not limited to this, and various resin mounting members and various resin components may be used.
