Abstract

PURPOSE: To prevent a boss for protecting a surface of a resin molding body from being folded during transportation and assembly. CONSTITUTION: A boss 2 is formed integrally with a resin molding body 1 through a hinge 2a and protrudes from the surface of the resin molding body. A stopper 3 for receiving the boss 2 when the boss 2 supports the resin molding body 1 and deforms is provided integrally with the resin molding body 1 at a position opposite to the boss 2.

Description

Detailed Description of the Invention

[0001]

This invention relates to a resin molded product,
In particular, it relates to the structure of a boss that supports a resin molded product during transportation or assembly of parts.

[0002]

2. Description of the Related Art For resin molded products such as panels of electronic devices,
There is a boss provided for protection in order to prevent flaws from being formed during transportation or to prevent deformation of a resin molded product when it has a hinge or a knob. These bosses are not needed in the final product where resin molded products are used,
It is easy to remove when assembling.

FIG. 7 shows an example of a boss of a panel of such an electronic device. As shown in the figure, the boss 2 is integrally formed with the panel body 1 via a thin portion. The boss 2 was sometimes broken at the thin portion during transportation.

FIG. 8 shows a state in which parts are assembled on the back surface of this panel. First, after removing the boss, the panel 1 is placed on a dedicated jig 6 adapted to its surface shape, as shown in FIG. In this way, the panel is prevented from being scratched and wobble is prevented. Then, as shown in FIG. 8B, the component 7,
7 is assembled. Generally, there are many types of panels handled on the production line, and many types of jigs 6 are required to match the shape of the panels. Furthermore, even when there are multiple lines for producing the same product, multiple jigs are required. Therefore, the manufacturing cost was increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and an object thereof is to prevent the boss from breaking during transportation and to assemble the parts into the resin molded product. An object is to provide a structure of a resin molded product that does not require a jig when attaching.

[0006]

According to the structure of a resin molded product of the present invention, a boss connected to the main body via a hinge portion is projected from the surface of the resin molded product, and a stopper for receiving the boss when the boss is deformed is provided in the main body. It was installed in.

Further, in the structure of the resin molded product, the resin molded product is a panel of an electronic device.

[0008]

According to the structure of the resin molded product of the present invention, the surface of the resin molded product can be protected by supporting the panel by the boss during transportation. Although the boss is deformed by the hinge portion, since it is supported by the stopper, the deformation of the hinge is suppressed within a certain range and the hinge is not broken.

When a component is mounted on the resin molded product, the resin molded product can be stably supported by supporting the resin molded product by a boss even if the surface of the resin molded product is formed into a curved surface. No scratches on the surface of resin molded products.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A panel structure of an electronic device according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a panel of an electronic device according to an embodiment of the present invention. As shown in the figure, four bosses 2, 2 ... Are integrally provided with the panel body 1 so as to project from the surface of the panel body 1.
As shown in detail in FIG. 2, the boss 2 is connected to the main body 1 via a hinge portion 2a. A stopper 3 is provided integrally with the panel body 1 at a position facing the boss 2.

FIG. 3A shows a state in which the panel body 1 is stored or transported. Panel body 1,
1 ... are stacked via partition plates 5, 5. At this time, the boss 2 is deformed at the hinge portion and becomes oblique. FIG.
The deformed state of the boss 2 is shown in (b). The boss 2 is deformed and becomes oblique, and is supported by the stopper 3.

When the boss 2 comes into contact with the stopper 3, the hinge portion is not further deformed and the hinge portion is not broken. In such a state, the surface of the panel body 1 does not come into contact with the partition plate 5 and is not scratched. Since the hinge portion 2a is thin, the boss 2 can be easily removed by twisting. After removing the boss 2, as shown in FIG.
Is attached and the hinge part 2a is hidden after being folded. Boss 2
Even if it is not removed, the decorative panel 4 may be attached by bending the hinge portion 2a and tilting the boss 2 to the side opposite to the stopper 3 as shown in FIG.

FIG. 4 shows a state in which the components 7, 7 are attached to the panel body 1. The panel body 1 is supported by the bosses 2 and 2 and is stable, and since the surface does not contact the workbench, the surface of the panel body 1 is not scratched. At this time, the boss 2 is in contact with the stopper 3 in an inclined manner as shown in FIG. The order of transportation and assembly is arbitrary, and transportation and assembly may be repeated multiple times.

[0014]

According to the structure of the resin molded product of the present invention,
The boss that protects the surface of the resin molded product body during transportation and assembly does not break, and can be easily removed when it is no longer needed. Further, a jig for assembling is unnecessary.
