Abstract

(57) [Summary] [Purpose] To reinforce resin molded products. [Structure] A spacer 8 is guided by a positioning rib 6 and press-fitted into a V-shaped section 5. In a state where the spacer 8 is fitted into the V-shaped section 5, the protrusion 9 is fitted into the square hole 7. As a result, the spacer 8 fits into the V-shaped section 5 of the resin molded product, thereby reinforcing the resin molded product and preventing its deformation.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the reinforcement structure of resin molded products. This invention relates to a reinforcing structure for automotive resin molded products such as car meter hoods.

0002

[Conventional technology]

Conventionally, a meter hood 51 as shown in Fig. 10 has been used as a resin molded product for automobiles. It is used. Such a resin molded product has a cross section like the V-shaped section 52 at the bottom. It may have a V-shaped portion. This V-shaped section 52 is indicated by the dotted line 5 in FIG. As shown in 2a, there are some problems that occur during molding due to the material, molding conditions, mold structure, etc. Therefore, it is normal for some deformation to occur. Such transformations are, for example, If it is the lower part of the meter hood 51, it is not desirable in terms of design and is difficult to visually recognize the meter. Not good either. Note that the lower part of the meter hood 51 is a part that is easily deformed by heat. It's a minute.

0003

[Problem that the idea aims to solve]

Here, as shown in FIG. 12, deformation prevention ribs 53 are provided on the V-shaped section 52. There is something set up. However, when this rib 53 is provided, sink marks 54 or wavy 55, which still had its drawbacks.

0004

[Means to solve the problem]

This invention was made in view of the above circumstances, and it A spacer is provided corresponding to the approximately V-shaped section, and a spacer that fits into the V-shaped section is provided, and the upper In order to prevent the V-shaped section from being deformed, the spacer is fitted into the V-shaped section. This provides a reinforcing structure for resin molded products.

[0005]

[Effect]

This invention uses a spacer with a V-shaped cross section that fits into the V-shaped cross section of the resin molded product. This strengthens the resin molded product and prevents it from deforming.

[0006]

【Example】

The resin molded product according to the present invention will be described below with reference to the examples shown in the attached drawings. Explain the reinforcement structure.

[0007] Figure 1 shows an instrument panel 1 equipped with a meter hood to which the present invention is applied. In the figure, 2 is the position where the meter hood is attached, 3 is the cigarette lighter, This shows the location where the garnish panel for the air conditioner control panel, etc. is installed.

[0008] 2 to 6 show a meter hood 4 to which the present invention is applied. This invention is related to The reinforcing structure is applied to the lower part 5 (FIGS. 2 and 3) of the meter hood 4. Below this The section 5 is formed as a V-shaped section 5, as shown in FIGS. Figure 3 As shown in , this V-shaped section 5 has a space described later on one side 5a. A positioning rib 6 is provided on the other side 5b, and a square serving as a locking means is provided. A hole 7 is provided.

[0009] Further, FIG. 7 shows a spacer 8 that fits into the V-shaped section 5. This space The sleeve 7 has a V-shaped cross section, and has an outer shape that closely fits the V-shaped cross section 5. do. Further, this spacer 8 is integrally provided with a protrusion 9 that fits into the square hole 7. . By the way, although this spacer 8 has a hollow part 10, it is of course not dense. can also be configured. Furthermore, reinforcing ribs 11 may be provided within this hollow portion 10. Ru.

0010 In the above embodiment, the spacer 8 is located at the above-mentioned position in the above-mentioned V-shaped section 5. It is guided by the determining rib 6 and press-fitted. In the state fitted to the V-shaped section 5 Then, as shown in FIG. 8, the protrusion 9 fits into the square hole 7. by this , the spacer 8 is prevented from falling off.

[0011] In this example, the above spacers are fitted in two positions on the left and right, but depending on the target They can be provided at an appropriate number of positions depending on the resin molded product.

0012 Due to the reinforcing structure according to the above embodiment, warping, sink marks, and waving of the V-shaped section 5 can be prevented. deformation and thermal deformation are prevented. Furthermore, by lining the spacer 8, this The rigidity of the part is also strengthened. Note that spacer 8 is of the same type as the meter hood and is installed at the same time. Since it can be molded, there is no burden on the process for manufacturing the spacer 8 itself.

[0013] The present invention is applicable not only to the above-mentioned meter hood, but also to other resin molded products, such as the garnish shown in Figure 9. It can also be applied to the roughly V-shaped section 13 of the panel 12, and can be applied not only to automotive accessories. It can also be applied to other resin molded products.

[0014]

[Effect of the idea]

According to the present invention, a spacer having a V-shaped cross section that fits into a V-shaped cross-sectional part of a resin molded product. This strengthens the resin molded product and prevents it from deforming. At the same time, the rigidity is also strengthened. Additionally, the spacer is simply press-fitted during the manufacturing process. It is superior in many respects, such as being less burdensome because it can be carried out with only one person.
