Description

  The present invention relates to a resin-molded resin member mounting structure that is mounted on a vehicle.

Speaking of a resin member attached to a vehicle, for example, there is an air conditioning duct. As a conventional example, a deformed portion that is expanded and deformed by a pressing force and is formed in a shape that can maintain the expanded deformed state is provided in the mounting portion of the resin part that is mounted on the mounted portion. There is a resin component mounting structure (see, for example, Patent Document 1) in which a resin component is fixed to a mounted portion by an expanding deformation action and a maintaining action thereof.
JP 2002-327716 A (refer to the claims section, detailed description section, and FIGS. 1 to 5)

In the prior art, the mounting portion of the duct is provided with a deforming portion that is expanded and deformed by a pressing force and is formed in a shape capable of maintaining the expanding deformation.
However, since the plate-shaped member is simply expanded, the expansion deforming portion has a problem that the base portion of the mounting portion has a plate-like cross section, so that the section modulus is low and the rigidity in the lateral direction is low.
An object of the present invention is to solve the above problems and to provide a mounting structure for a resin molded product that can be molded together with a resin molded product and can form a locking piece with a simple operation.

A first invention of the present invention for solving the above problems is a mounting structure in a resin molded product as described in claim 1, and is as follows.
A contact portion is formed at the base portion of the resin molded product, extending pieces are respectively extended to the corresponding contact portions via a plurality of hinges, and the extending portions are rotated and overlapped to form a locking piece. It is the structure which forms.

A second invention of the present invention for solving the above problem is an attachment structure in a resin molded product as described in claim 2, and is as follows.
In addition to the invention described in claim 1, the contact portion is a recessed portion, the hinge is formed at the base end of the recessed portion, and the extending piece is formed in a bent plate shape. It is.

A third invention of the present invention for solving the above-mentioned problems is a mounting structure for a resin part as described in claim 3, and is as follows.
In addition to the invention described in claim 1 or 2, the extending piece has a configuration in which holding means for holding the polymerization state is formed.

Since the mounting structure in the resin molded product according to the present invention is configured as described above, the following effects can be obtained.
(1) According to the invention described in claim 1, although it is supported by the support portion formed with a simple structure, a highly rigid locking structure can be obtained.
(2) According to the invention described in claim 2, since the locking piece is formed by the concave member and the bent plate-like member, the section modulus can be increased while being lightweight, so that the moldability is good and the weight is high and the rigidity is high. A locking piece can be formed.
(3) According to the invention described in claim 3, the weight reduction and workability of the resin molded product are improved as a structure for holding by the holding means (for example, press-fitting boss and hole).

  A contact portion provided as a recessed portion is formed at the base of the resin molded product, and extending pieces are extended to the left and right via hinges at the left and right base ends of the corresponding contact portion, and formed into a bent plate shape. The mounting structure for the resin molded product that forms the locking piece by rotating and superposing the extending piece on which the holding means for holding the polymerization state is formed.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 6A is a view in FIG. -A line schematic cross-sectional view, (b) is a schematic cross-sectional view showing a state where the hinge portion of the clip-shaped portion is bent, and (c) is attached by inserting the clip-shaped portion into a hole provided in a mating part such as a panel. Indicates the state FIG. 7 is a schematic cross-sectional view, FIG. 7 is a schematic cross-sectional view showing a second embodiment of the clip-shaped portion of the mounting structure in the resin molded product of the present invention, and FIG. FIG. 9 is a schematic sectional view showing a third embodiment, and FIG. 9 is a schematic sectional view showing a fourth embodiment of the clip-shaped portion of the mounting structure in the resin molded product of the invention.

  The feature of the present invention is that the bracket portion 2 is formed on the base portion 14 shown in FIGS. 1 to 4, and the clip-shaped portion 1 extended through the left and right hinge portions 3 provided on the bracket portion 2 is provided. As shown in FIG. 6 (a), the clip-shaped part 1 formed by being divided into halves as shown in FIG. 6 (a) is bent by the hinge part 3 to form one insertion clip shape {FIG. 6 (b). ) And (c)} so that the resin molded product can be attached to the vehicle body or the like by being inserted into the hole 5 provided in the counterpart component 12 such as a panel.

Here, an embodiment of the mounting structure in the resin molded product of the present invention will be described in detail with reference to the drawings.
As can be understood from FIGS. 1 and 2, the clip-shaped portion 1 and the bracket portion 2 can be integrally formed without using a special mechanism for the molding die.
A hinge portion 3 {see FIG. 6 (a)} provided between the clip-shaped portion 1 and the bracket portion 2 is folded downward to form a clip shape 4 by overlapping the left and right clip-shaped portions 1. Yes {see Fig. 6 (b), (c)}.
Then, the resin molded product can be easily attached to the counterpart component 12 by being inserted into the hole 5 provided in the counterpart component 12 such as a panel (see FIG. 6C).
In addition, when the clip hooking portion 6 when the clip shape 4 is inserted into the hole portion 5 gets over the mating hole portion 5, the clip neck portion 7 is bent and the clip shape 4 is attached to the hole portion 5 of the mating component 12. Even in the state, the clip neck portion 7 remains bent, so that the structure is difficult to come off.
Further, in the state of being attached to the counterpart part 12, the surface of the concave portion 8 also serving as reinforcement from the hinge portion 3 to the clip shape 4 is brought into contact with the surface of the concave portion 9 also serving as reinforcement of the bracket portion 2. The angle at which the hinge portion 3 bends can be fixed, the position where the clip shape 4 is applied can be restricted, and the insertion force is too strong so that the clip neck portion 7 gets over the hole portion 5 of the mating part 12. It is possible to prevent the clip shape 4 from being inserted.

Next, another embodiment of the mounting structure for the resin molded product of the present invention will be described with reference to the drawings.
FIG. 7 shows a second embodiment in which the clip shape 4 can be more easily removed from the hole portion 5 by providing the contact surface 10 near the clip neck portion 7.
FIG. 8 shows a third embodiment when the mounting angle of the mating component 12 is different. For example, when mounting to the diagonal mating component 12, the tip of the clip shape 4 is matched to the diagonal shape. By adjusting the length from to the clip hooking portion 6, it can be molded appropriately according to the situation of the mating member.
FIG. 9 shows a fourth embodiment in which a hook shape 13 is set and a clip shape 4 divided into two is temporarily fixed in a bent state.

Further, in all of the above-described embodiments, as shown in FIG. 5, the concave and convex portions 11 are respectively provided at the tips of the clip-shaped portions 1 formed by being divided into halves, and the clip-shaped overlapping state is maintained. It is also possible to form means.
As this holding means, various holding means such as a claw part in addition to the uneven shape part 11 can be considered.

  It can be used as an attachment structure for various automobile resin members and vehicle bodies.
