用されている。2. Description of the Related Art In recent years, foldable mobile phones have become widespread, but in the foldable mobile phones, it is necessary to increase the strength of the hinge structure between housings. For this reason, it is preferable to use a material that is lightweight, has rigidity, and is excellent in workability as the material that constitutes the housing of the mobile phone. An injection-molded product of a thermoplastic, which is mainly made of a fiber-reinforced high-rigidity resin, a die-cast product of a magnesium alloy or the like, and an injection-molded product of the thixomold method or the like are used. Further, in the case of using an ordinary plastic molded product, a method of maintaining rigidity by increasing the number of parts or devising an internal structure is also adopted.

【発明が解決しようとする課題】ところが、繊維補強高
剛性樹脂のような熱可塑性プラスチックで筐体を構成す
ると、剛性を高めるために多量の繊維を混入するので、

肉状態が起こりやすくなる。その第２は、樹脂の流入方
向によっては繊維の配向が起きるため、衝撃強度が弱く
なる。したがって、ヒンジ構造の剛性が低下してしまう
問題があった。However, if the housing is made of a thermoplastic such as a fiber-reinforced high-rigidity resin, a large amount of fibers are mixed in order to increase the rigidity.
There is an adverse effect due to this. The first is that by mixing fibers, the fluidity of the plastic decreases, so
A thin wall portion, a deep rib portion, or the like is likely to have a lack of wall thickness. Secondly, the impact strength is weakened because the fibers are oriented depending on the resin inflow direction. Therefore, there is a problem that the rigidity of the hinge structure is reduced.
【０００４】一方、内部構造により剛性を維持しようと
すると、部品点数の増加を招き、コストアップや組立工
数の増加等が生じる問題がある。On the other hand, if the rigidity is to be maintained by the internal structure, the number of parts is increased, and there is a problem that the cost is increased and the number of assembling steps is increased.

問題があった。Further, in the die casting method using a magnesium alloy or the like, not only a surplus portion called a burr is easily formed, but also a surface defect called a wrinkle is likely to be formed depending on the flow of the hot water. There was a problem that it was necessary to remove the meat portion and polish the surface defect portion.

The rigidity of the hinge structure is ensured not only by the lack of thickness, but also by not increasing the number of parts and the number of assembling steps, and by eliminating the work of removing the excess thickness after molding. It is an object of the present invention to provide a mobile phone and an electronic device that can be improved to a high level, and an object of the present invention is to provide a method of manufacturing a hinge mechanism that can accurately manufacture the hinge structure.

As shown in FIGS. 2 and 3, the insertion portion 21d is formed in a U shape so that it can be inserted into the base portion of the operation-side housing 10A, and is formed integrally with the first hinge 21. The fourth reinforcing portion 24d is embedded inside. The fourth reinforcing portion 24d is also made of the same material as the first to third reinforcing portions 24a to 24c and is integrally formed. Therefore, the reinforcing member 24 is configured to have the first to fourth reinforcing portions 24a to 24d.

機メッキ処理されている。The first hinge 21 as described above is manufactured in advance before the molten material of the synthetic resin is injected into the molding die.
The molding die is opened and the reinforcing material 24 is set therein. Considering the adhesiveness of the first hinge 21 with the synthetic resin, the reinforcing material 24 is preliminarily subjected to an organic plating treatment before being set in the molding die.

している。Then, after closing the molding die, the synthetic resin molten material is injected in the same manner as in ordinary injection molding.
The molten material goes around the reinforcing material 24 in the molding die and hardens in that state, whereby the first hinge 21 is formed. Therefore, the first hinge 21
Is embedded so as to cover the reinforcing material 24 inside the synthetic resin.

On the other hand, although not shown in detail, the second hinge 22 provided in the display-side housing 10B corresponds to the first hinge 21, and is made of a metal similar to the first hinge 21 inside the synthetic resin. A reinforcing material (not shown) is embedded.

0 is equipped with the hinge mechanism 20 having the first hinge 21 in which the reinforcing material 24 is embedded inside the synthetic resin. When the reinforcing material 24 is made of metal, the hinge pin 23 is inserted in the first hinge 21. The rigidity of the portion to be covered is surely increased, the rigidity which cannot be obtained by the plastic material alone can be secured, and the rigidity of the hinge mechanism 20 can be increased accordingly. Moreover, since the reinforcing member 24 has a shape conforming to the shape of the first hinge 21, it is possible to easily obtain the rigidity of the portion required for strength.

工数の増加を招くおそれがない。Therefore, since the operation side casing 10A can be formed of a general synthetic resin material, it becomes unnecessary to use the conventional fiber-reinforced high-rigidity plastic or the like, and a state of lack of thickness may occur. It is possible to prevent the impact strength from decreasing. Further, since the structure can be simplified by ensuring the rigidity, it is not necessary to increase the number of parts as in the conventional case, and the number of assembling steps is not likely to increase.

から好ましい。Further, since the first hinge 21 is formed by embedding the reinforcing material 24 made of magnesium alloy or the like in the synthetic resin, the reinforcing material 24 is not exposed on the surface,
Therefore, even if a metal is used, surface defects such as burrs can be tolerated to some extent, and the manufacturing yield can be improved accordingly. Things like this
By forming not only the first hinge 21 but also the second hinge 22 in the same manner, the rigidity of the hinge mechanism 20 can be further enhanced, which is more effective. When a magnesium alloy is used as the reinforcing material 24 embedded in the first hinge 21 and the second hinge 22, the magnesium alloy has a lower specific gravity than the copper alloy or the aluminum alloy, which is preferable from the viewpoint of further weight reduction.

ンジ２１を的確に製造することができる。Furthermore, when the first hinge 21 is molded, the reinforcing material 24 is set in the molding die of the first hinge 21 in advance, and then the molten resin of synthetic resin is injected into the molding die. Since the first hinge 21 is embedded in the synthetic resin forming the first hinge 21, the first hinge 21 having the metal reinforcing member 24 can be manufactured accurately.

When the first hinge 21 is molded in that state, the reinforcing material 2 is formed by the chemical bonding layer.
4 and the synthetic resin firmly adhere to each other, the first hinge 21
The rigidity of can be further increased.

Although the first hinge 21 is mainly described, the rigidity of the hinge mechanism 20 can be assured as long as one of the first hinge 21 and the second hinge 22 has the reinforcing member 24 embedded therein. It can be raised. Also,
The first hinge 21 is formed in a shape having the pin insertion portions 21a to 21c, but the shape is not limited to such a shape. Furthermore, although an example applied to the mobile phone 10 is shown, another one having a hinge mechanism 20 that is small and lightweight and is configured to open and close the housing, for example, a PDA.
It can also be applied to a (personal digital assistant) or an electronic device such as a notebook computer.

However, for example, knurling or the like is provided on the surface of the reinforcing material 24 so that the reinforcing material 24 is formed by the unevenness. And the first hinge 21
The adhesiveness between the synthetic resin and the synthetic resin may be secured, and further the adhesiveness may be secured by an adhesive. The point is that a desired adhesive force can be obtained between the metal and the synthetic resin material. Any one may be used as long as it is possible.
