Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting structure for reliably connecting and fixing a synthetic resin molded part to another member such as metal.

As a conventional example related to the above, when a molding member 2 as a decorative part is connected and fixed to the front surface of a bumper 1 of an automobile as shown in FIG. 1, a clip 3 (see FIG. 2) is connected integrally with the molding member 2.
A structure is used in which a plurality of clips 3 are provided, the clips 3 are inserted into connection holes provided in the bumper 1, and the molding member 2 is fixed to the bumper 1 by its elastic force. However, in the configuration as described above, since the tips of the seat portions 3a, 3a of the clip 3 are integrally connected to the wall surface of the molding member 2, a minute recess is formed on the surface of the molding member corresponding to the back side of this connecting portion. 4,4 may appear. The recess 4,
4 is naturally generated during cooling after molding during manufacturing of the molding member, and significantly impairs the appearance characteristics.When the wall thickness of the molding member 2 is small, the recesses 4, 4 are It has a distinctive feature. Furthermore, in the above configuration, when a large external load is applied from the front of the molding member 2, the clip 3
Since the molding member 2 itself is not structured to withstand a large load, it has the disadvantage that the molding member 2 easily deforms. Moreover, when the overall length of the clip 3 becomes longer, the attachment stability of the clip 3 deteriorates, and the posture of the molding member 2 cannot be maintained normally.
It also has the disadvantage that the workability of inserting the bumper 1 into the bumper 1 is reduced.

The purpose of the present invention is to obtain a structure that eliminates the various drawbacks that exist in the conventional mounting structure of resin molded products such as molding members as described above. an insertion protrusion that protrudes into and locks into a connecting hole provided in the connecting hole, a locking portion having spring characteristics, a seat extending from the locking portion toward the combined body, and a bridge-shaped extension extending from the side wall of the seat. and a base portion that is connected and fixed to an arbitrary connecting portion on the composite body such as the resin molded product,
The present invention provides a mounting structure for a resin molded product, characterized in that a bonded body is connected and fixed to the body to be bonded.

The mounting structure for a resin molded product according to the present invention will be described in detail below based on the drawings. That is, in FIG. 3, 11 is a bumper of an automobile, and the bumper 1
A molding member 12, which is a resin molded product, is connected and fixed in a recess provided on the front side of the molding member 1. As is clear from the cross-sectional structure shown in FIG. 3 and the partial perspective view shown in FIG. 4, the fixing structure of the molding member 12 includes an insertion protrusion 13 that protrudes and locks into a connecting hole provided on the bumper 11 side. , a locking portion 14 having spring characteristics for locking the bumper 11 in the same manner, and a seat portion 1 extending from the locking portion toward the molding member 12 which is a combined body.
5, 15, and a base 1 extending in a bridge shape from the side walls of the seat portions 15, 15 and connected and fixed by arbitrary connecting portions 16, 16 of the molding member 12.
It consists of 7 and 17. The seat portions 15, 15
The seat portions 15, 15 and the molding member 12 are not normally connected to each other, and the seat portions 15, 15 and the molding member 12 are not normally connected to each other.
Furthermore, the connecting parts 16, 16 of the base parts 17, 17 to the molding member 12 are located at the corners of the molding member 12, as shown in FIG. A position that does not appear is selected.

With the above configuration, the insertion protrusion 13 can be inserted into the connecting hole provided on the bumper 11 side, and the molding member 12 can be attached to the bumper 11 by the locking part 14. Part 15,
15 functions as a support when a larger external load is applied to the front surface of the molding member 12, and has the effect of preventing deformation such as denting of the molding member 12. Moreover, since the seat portions 15, 15 and the molding member 12 are not connected, there is no possibility that a recess or the like will be formed on the front side of the molding member 12. On the other hand, base portions 17, 17 extending in a bridge shape from the side walls of the seat portions 15, 15 support the molding member 12 by connecting portions 16, 16, but the connecting portions 16, 16 have recesses on their surfaces. An appropriate position can be selected, such as a corner portion (FIG. 3) where the concave portion does not appear, or a portion where the external appearance is not affected even if the concave portion appears. Even if the base portions 17, 17 extend slightly outward as a result, the seat portions 15, 15 work effectively to effectively support the load from the outside, thereby increasing the mounting strength. This exhibits the effect of preventing deterioration of the molding member 12 and preventing deformation of the molding member 12. That is, in the present invention, the base portions 17, 17 connected to the molding member 12,
The seats 15, 15 provided between the two interact with each other to maintain the mounting strength and prevent deformation, and the appearance characteristics are improved by eliminating the occurrence of recesses that were conventionally seen on the surface of the molding member 12. improves. Therefore, it is not necessary to make the wall thickness of the molding member 12 unnecessarily large, and it also has the effect of reducing material costs, and is particularly suitable for use when decorative molding is applied to automobile bumpers. It is highly effective.
