Description

  The present invention relates to a portable terminal having a dustproof or waterproof structure.

  2. Description of the Related Art Conventionally, it has been known that a portable terminal represented by a mobile phone has a waterproof structure in consideration of being used during work around water or being accidentally dropped into water.

  For example, in Patent Document 1, a light guide plate is insert-molded on the outer surface side of a waterproof member made of a film-like packing made of transparent rubber to cover an interior such as a liquid crystal display panel. Thus, not only a waterproof function is achieved, but also a logo or the like can be displayed by illumination from the light guide plate in the illumination unit.

JP 2008-106932 A

  However, in the portable terminal of Patent Document 1, since the waterproof member is a film that covers most of the inside of the housing, it is inevitable that the size of the parts is large and the thickness of the entire portable terminal is increased. There was a problem.

  The present invention has been made in view of such a point, and the object of the present invention is to make a dust-proof or waterproof portable terminal easy to assemble with a simple configuration using an annular packing and to be compact and highly decorative. It is to do.

  In order to achieve the above object, in the present invention, a permeable resin is integrally formed in a permeable annular elastic portion.

Specifically, the present invention is premised on a portable terminal having a portable terminal body that is dustproof or waterproof by sandwiching a packing between the outer peripheral edge of the first cabinet and the outer peripheral edge of the second cabinet. ,
The packing includes a transparent or translucent annular elastic portion, and a transparent or translucent resin portion provided integrally with at least a part of the elastic portion,
Provided with an illuminating unit for entering light into the packing inside the packing in the mobile terminal body,
At least a part of the packing is exposed from the outer peripheral edge of the mobile terminal body, and light from the illumination unit is guided to the exposed part of the packing.

  According to the above configuration, the packing made of an annular elastic portion that has been conventionally used is made permeable, and the permeable resin portion is also integrally formed with the elastic portion. Light can be emitted by guiding light. For this reason, it is possible to provide a portion that emits light at a desired position with a simple configuration.

In particular , in the first invention,
The resin part is disposed on the opposite side of the illumination part from the elastic part, and at least a part of the resin part is exposed,
The light entering the elastic part is guided to the exposed resin part to emit light.

According to said structure, a resin part should just be integrally molded to an elastic part only at the location which needs light emission, and since a hard resin part is exposed from a portable terminal main body, an external appearance is good and durability is high. In addition, if the shape or material of the resin part diffuses light, a wide range of light can be emitted .

More particularly in the second invention,
The resin part is disposed closer to the illumination part than the elastic part,
The outer resin part is further arranged on the opposite side of the illumination part from the elastic part, and the outer resin part is exposed,
The light guided to the elastic part via the resin part is further guided to the outer resin part to emit light.

  According to the above configuration, the resin portion is integrally formed inside the elastic portion where light emission is necessary, and the outer resin portion is provided outside the elastic portion to expose the hard outer resin portion from the mobile terminal body. Therefore, the appearance is good and the durability is high. Moreover, since the light from the illumination part is efficiently guided by the inner resin part, it is not necessary to provide a light guide plate. If the shape and material of the outer resin part diffuse light, a wide range of light can be emitted.

In the third invention, in the first or second invention,
A light guide plate is disposed between the illumination unit and the packing, and light from the illumination unit is guided to the packing by the light guide plate.

  According to said structure, even if it is one illumination part, light emission in a wide range becomes easy by providing a light-guide plate.

In a fourth invention, in any one of the first to third inventions,
Since the resin portion is integrally formed with the elastic portion, the packing maintains a three-dimensional shape corresponding to the unevenness of the groove portion provided in the outer peripheral edge portion of the first cabinet or the outer peripheral edge portion of the second cabinet.

  According to said structure, it becomes very easy to engage | insert a packing in a groove part by making a packing into a three-dimensional shape by a resin part. Further, it is easy to position the exposed portion of the packing.

  As described above, according to the present invention, at least a part of the packing is exposed from the outer peripheral edge of the mobile terminal body, and the light from the illumination unit is guided to the exposed part of the packing. A waterproof portable terminal can be easily assembled with a simple configuration using an annular packing and can be made compact and highly decorative.

FIG. 3 is a partially enlarged front view of FIG. 2. FIG. 6 is a view corresponding to FIG. 1 and showing a first modification of the embodiment. FIG. 9 is a view corresponding to FIG. 1 and showing a second modification of the embodiment. FIG. 2 is a view corresponding to FIG. 1 illustrating a reference example of the embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  2 and 3 show a mobile phone 1 as a mobile terminal according to an embodiment of the present invention. The mobile phone 1 includes, for example, a first housing 3 having a display unit (not shown) on the surface, and a surface. A second housing 5 as a mobile terminal body having an operation unit 4 (shown in FIG. 4) is connected via a hinge unit 6 so as to be foldable.

  As shown in FIGS. 4 and 5, the second housing 5 includes a front side first cabinet 7 and a back side second cabinet 8, which are overlapped and coupled with screws or the like. ing. The first cabinet 7 and the second cabinet 8 are made of, for example, a resin molded product.

  As shown in FIG. 6, a groove 9 is continuously formed on the outer peripheral edge of the second cabinet 8, and a waterproof packing 10 is fitted in the groove 9. On the other hand, as shown in FIG. 5, waterproof ribs 11 for pressing the waterproof packing 10 are formed on the outer peripheral edge of the first cabinet 7 at positions facing the groove 9 over almost the entire circumference. When the first cabinet 7 and the second cabinet 8 are overlapped and joined, the waterproof casing 10 fitted in the groove 9 is sandwiched between the groove 9 and the waterproof rib 11 so that the second housing The waterproof function in 5 is demonstrated. The back side of the second cabinet is covered with a lid or a decorative member 18.

  As shown in FIGS. 1 and 7 in an enlarged manner, the waterproof packing 10 includes a silicone rubber 12 as a transparent or translucent annular elastic portion. In addition, you may comprise an elastic part with elastic members, such as transparent or translucent urethane rubber which is not the silicone rubber 12. FIG. The higher transparency of the elastic part is desirable, but it may be at least enough to transmit the light of the LED 20 described later. The silicone rubber 12 has a shape corresponding to the shape of the groove 9, and a polycarbonate resin 13 as a transparent or translucent resin portion is integrally formed on the silicone rubber 12. The resin portion may be formed of a transparent or translucent elastic member that is not the polycarbonate resin 13. Although it is better that the transparency of the resin part is higher, it may be at least enough to transmit the light of the LED 20, or may be colored with emphasis on the appearance. In this embodiment, in order to stabilize the shape of the silicone rubber 12, the polycarbonate resin 13 is integrally formed on the outer side (or the inner side) of the annular silicone rubber 12 almost entirely. The polycarbonate resin 13 may be integrally formed only on a part of the polycarbonate resin 13 instead of being provided almost all around.

  As shown in FIG. 1, the substrate 14 is fitted inside the waterproof packing 10 in the second housing 5. The substrate 14 may be provided in either the first cabinet 7 or the second cabinet 8. The board 14 is provided with an LED 20 as an illuminating unit for entering light into the waterproof packing 10. Specifically, as shown in FIG. 6, a pair of LEDs 20 is provided on the upper side (on the hinge portion 6 side) of the substrate 14 with a space left and right. The color, size, number, and the like of the LED 20 are not particularly limited. A light incident hole 15 is opened on the wall surface of the groove 9 above the LED 20 so as to correspond to the LED 20. As shown in FIGS. 2 and 3, a pair of exposure holes 16 are opened in the upper wall of the second cabinet 8 above the groove 9. For example, the exposure hole 16 is rectangular, but the size and shape are not particularly limited. A rectangular parallelepiped light emitting portion 17 is integrally formed outside the silicone rubber 12 corresponding to the exposed hole 16. For example, only the vicinity of the light emitting portion 17 may be composed of the polycarbonate resin 13 having high transparency, and the other portions may be composed of the polycarbonate resin 13 having low transparency or other resins. It should be a material.

  With this configuration, when the waterproof packing 10 is fitted into the groove portion 9, the three-dimensional shape is maintained by the polycarbonate resin 13 that is thinly integrally formed on almost the entire circumference of the silicone rubber 12, so that it is easily positioned. As a result, the light emitting portion 17 is easily fitted into the exposure hole 16 and is exposed from the exposure hole 16.

  When the LED 20 shines, the light passes through the light incident hole 15, is introduced into the silicone rubber 12, is further guided to the light emitting unit 17, and the light emitting unit 17 emits light. As described above, the waterproof packing 10 made of the annular silicone rubber 12 conventionally used for waterproofing is made permeable, and the permeable polycarbonate resin 13 is also integrally formed on the silicone rubber 12, thereby Light from the LED 20 is guided by the waterproof packing 10 to emit light.

  Alternatively, the polycarbonate resin 13 can be integrally formed with the silicone rubber 12 only at the locations where light emission is necessary. Since the hard polycarbonate resin 13 is exposed from the second casing 5 (second cabinet 8), the appearance is good and the durability is high. Furthermore, if the shape and material of the polycarbonate resin 13 are made to diffuse light, a wide range of light can be emitted.

  Therefore, according to the mobile phone 1 according to the present embodiment, at least a part of the waterproof packing 10 is exposed from the outer peripheral edge of the second housing 5 and the light from the LED 20 is guided to the light emitting unit 17. By using the annular waterproof packing 10, the mobile phone 1 can be easily assembled, compact, and highly decorative.

-Modification 1-
FIG. 8 shows a first modification of the embodiment of the present invention, which differs from the above embodiment in that a light guide plate 21 is arranged. In the following modifications and reference examples , the same portions as those in FIGS. 1 to 7 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In this modification, a light guide plate 21 is disposed between the LED 20 and the silicone rubber 12. For example, the light guide plate 21 is made of a resin having a small light guide loss, such as polycarbonate resin and acrylic resin, which is subjected to groove processing. The light guide plate 21 guides or diffuses the light from the LED 20 to the waterproof packing 10. Since the light guide plate 21 can expand the range in which light can be introduced, the size of the light-emitting portion 17 can be increased by a small number of LEDs 20.

-Modification 2
FIG. 9 shows a second modification of the embodiment of the present invention, which differs from the above embodiment in that a polycarbonate resin 13 serving as a substitute for the light guide plate 21 is integrally formed.

  That is, the polycarbonate resin 13 is integrally formed not only on the outer side of the silicone rubber 12 but also on the inner side (the LED 20 side), and this polycarbonate resin 13 on the inner side has a role to replace the light guide plate 21. The light from the LED 20 is effectively guided to the silicone rubber 12 by the inner polycarbonate resin 13, and the light emitting portion 17 serving as the outer resin portion emits light reliably. Since the light guide plate 21 does not have to be provided in this way, light can be easily introduced without increasing the number of components. By exposing the hard outer resin portion from the second casing 5, the appearance is improved and the durability is increased.

-Reference example-
FIG. 10 shows a reference example of the embodiment of the present invention, which is different from the above embodiment in that the position of the silicone rubber 12 and the position of the polycarbonate resin 13 are opposite to each other.

In this reference example , the light from the LED 20 passes through the light incident hole 15 and is introduced into the polycarbonate resin 13. By extending the portion of the polycarbonate resin 13 toward the LED 20 as shown in FIG. 10, light can be easily introduced. The light introduced into the polycarbonate resin 13 is guided to the light emitting portion 17 where the silicone rubber 12 is exposed, and the light emitting portion 17 emits light.

In the present reference example , since the soft silicone rubber 12 is exposed to the outside, the second casing 5 is made of a material different from that of the second casing 5 and can be given an appearance characteristic of showing a different material.

(Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

  That is, in the above embodiment, the mobile phone 1 is a foldable type, and the mobile terminal body is the second housing 5, but the mobile terminal body is the first housing 3, or in the case of a straight type, The one case may be a portable terminal body.

  In the embodiment described above, the waterproof packing 10 surrounds the entire outer periphery of the second housing 5, but may also partially surround it. Moreover, although the light emission part 17 was set as the structure which exposes a part, it can also be exposed to the whole outer periphery, and when the whole is exposed, it also becomes possible to light-emit the whole outer periphery. The packing may not have a waterproof function but may have only a dustproof function.

  In the said embodiment, although the illumination part was LED20, it is not limited to this, You may use another illumination component.

  In the above embodiment, the mobile terminal is a mobile phone, but it may be a PHS (Personal Handy-phone System), a PDA (Personal Digital Assistant), a smartphone, a personal computer, a mobile tool, an electronic dictionary, a calculator, a game machine, or the like. Good.

  In addition, the above embodiment is an essentially preferable illustration, Comprising: It does not intend restrict | limiting the range of this invention, its application thing, or a use.
