Description

  The present invention relates to a waterproof cover and an electronic device using the same.

  Recently, the demand for highly waterproof electronic devices (for example, mobile phones) is gradually increasing. In order to improve the waterproofness of electronic equipment, it is necessary to improve the sealing performance around the insertion slot for precision parts and optical parts, as well as the part where batteries, shim cards or memory disks are inserted and removed. Taking the waterproof structure of the battery storage part that stores the battery as an example, the resin waterproof part that realizes waterproofing at the outer periphery of the opening surface of the battery storage part is fixed separately on the inner surface of the resin battery cover, While attaching a silicone elastomer or the like to a part of the waterproof part, a groove-like fitting part is formed on the outer periphery of the opening surface of the battery housing part, and the waterproof part on the battery lid side is press-fitted into the fitting part to provide waterproofing. A configuration to be realized (conventional configuration 1) is known. Further, as a similar structure, the battery lid and the waterproof portion are integrally formed to enhance the waterproofness between the battery lid and the electronic device body, and at the same time, the battery lid is made thinner by eliminating the adhesive thickness. A configuration (conventional configuration 2) is also known (see, for example, Patent Document 1).

Japanese Patent No. 4424445

  However, the above known battery lid has the following problems. First, in the case of the conventional configuration 1, since an adhesive layer such as an adhesive or a double-sided tape is required to attach the battery lid and the waterproof portion, the total thickness of the electronic device with the battery lid attached is large. This hinders thinning. On the other hand, when the battery lid and the waterproof part are integrally formed as in the conventional configuration 2, the adhesive layer is not necessary, and thus the thickness reduction is not hindered. However, a minute unevenness or distortion occurs on the outer surface of the battery lid, which causes another problem that the appearance of the battery lid is impaired. Specifically, a deformation region such as minute unevenness or distortion along the shape of the annular waterproof portion is generated outside the battery lid. One of the causes is that the protruding part of the waterproof part is used to prevent leakage of the elastomer in the process of setting the battery cover with the waterproof part integrated in the mold and fixing the elastomer to the protruding surface of the waterproof part. In order to apply pressure to the periphery of the mold and to heat the mold for the purpose of solidifying the elastomer, the periphery of the protruding portion is deformed. As a method of reducing the deformation region, a method of lowering the pressure at the time of mold clamping is conceivable. However, when the pressure is lowered, the liquid composition for forming the elastomer flows out from the original formation location, and the burr Generation of bubbles in the elastomer or sink on the bottom plate of the battery lid increases.

  An object of the present invention is to solve the above-described problems, that is, to realize a waterproof cover that achieves both a reduction in thickness of an electronic device and a good appearance of a lid member, and an electronic device including the same.

  In order to achieve the above object, an embodiment of the present invention provides a waterproof that can be attached to and exposed to an opening that communicates with the inside of the electronic device main body or a waterproof component that is attached to the electronic device main body. A cover body that covers an opening or a part of the electronic device body, and a waterproof member that is separate from the cover body and is fixed to the inside of the cover body. The waterproof cover is softer than the frame and has an elastic sealing material that covers the opening surface of the frame and the surface of the frame and adheres to the frame.

  Another embodiment of the present invention is a waterproof cover in which an elastic sealing material is continuously formed from the opening surface of the frame body to the surface of the frame body.

  Another embodiment of the present invention is a waterproof cover that further covers an opening surface of the frame body and an outer surface and / or an inner surface of the frame body with an elastic seal material.

  Another embodiment of the present invention further includes a frame-side convex portion or a frame-side concave portion on a surface of the frame body facing the cover body, and a frame-side convex portion or frame body side on the surface of the cover body facing the frame body. It is a waterproof cover that includes a cover main body side concave portion or a cover main body side convex portion to be fitted in each of the concave portions, and that fixes the frame body and the cover main body by fitting.

  Another embodiment of the present invention is a waterproof cover in which the frame and the inside of the cover body are fixed with a waterproof double-sided tape interposed therebetween.

  Another embodiment of the present invention is a waterproof cover further comprising a wide portion on the side to be fixed to the cover body, the frame having a wider width on the side fixed to the cover body than the width on the electronic device main body side. is there.

<First embodiment>
1. Configuration of Waterproof Cover and Electronic Device FIG. 1 is a partially exploded perspective view of an electronic device according to the first embodiment of the present invention.

  The electronic device 1 according to the first embodiment includes a waterproof cover 2 and an electronic device body 3. The waterproof cover 2 has a configuration that can be attached to the electronic device body 3 so as to cover and expose an opening that leads to the inside of the electronic device body 3 or a waterproof part that is attached to the electronic device body 3. Suitable examples include a battery housing portion in an opening communicating with the inside of the electronic device main body 3, and a memory disk or the like as a waterproof component attached to the electronic device main body 3, respectively. In the first embodiment, the waterproof cover 2 is configured to be attachable to the back surface of the electronic device main body 3. On the other hand, the electronic device main body 3 includes a battery storage unit 4. The battery housing part 4 is formed by opening the back surface of the electronic device main body 3 so that the battery 5 can be attached and detached. The electronic device main body 3 includes a groove 6 that is recessed in the inner direction of the electronic device main body 3 in a closed loop shape on the outer periphery of the battery housing portion 4. Moreover, the electronic device main body 3 includes a step end surface 7 that is recessed inward from the back surface on the outer periphery. The step end surface 7 is configured in a position and shape facing the end surface of the opening end of the waterproof cover 2.

  FIG. 2 is an exploded perspective view of the waterproof cover shown in FIG. 1 as seen from the side facing the electronic device main body after being disassembled into two components. FIG. 3 is a perspective view of the waterproof cover in a state where the constituent members shown in FIG. 2 are bonded to each other as viewed from the side facing the electronic device main body.

  The waterproof cover 2 is fixed to a cover main body 8 that covers the battery housing portion 4 of the electronic device main body 3 and a side (referred to as the inside) that is separate from the cover main body 8 and faces the electronic device main body 3 of the cover main body 8. The waterproof member 10 is provided. The cover body 8 can be preferably manufactured from resin, metal, ceramics or glass. When the cover body 8 is made of resin, the resin may be polycarbonate (PC), polyamide (PA), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), acrylonitrile / butadiene / styrene copolymer (ABS) resin, or the like. It can be used suitably. An inorganic filler or an organic filler may be dispersed in the cover body 8.

  FIG. 4 shows a cross-sectional view of the waterproof cover shown in FIG. FIG. 5 shows an enlarged view of the waterproof member shown in FIG. 4 and an enlarged view of a part B thereof.

  The waterproof member 10 can be suitably fixed to the entire inner surface of the cover body 8 via the adhesive layer 9. The adhesive layer 9 may be any layer having an adhesive function such as an adhesive layer, an adhesive ink layer, or a double-sided tape. In addition, the modification of the contact bonding layer 9 is demonstrated in another embodiment mentioned later. The waterproof member 10 includes a closed-loop frame 11 and an elastic seal material 12 that is softer than the frame 11 and covers the opening surface of the frame 11 and the surface of the frame 11 and adheres to the frame 11. Have. In the first embodiment, the frame body 11 has a form that can be inserted into the groove 6 formed in the electronic device main body 3, and is a substantially rectangular frame body. In the case where the outer shape of the groove 6 is a circle, an ellipse, a triangle, or a polygon that is a pentagon or more, the outer shape of the frame 11 is preferably a shape corresponding to the outer shape of the groove 6.

  The frame body 11 can be suitably configured from the same type of material as the cover body 8. The elastic sealing material 12 can be suitably manufactured from a thermoplastic elastomer, a thermosetting elastomer, natural rubber or the like, and in particular, a silicone elastomer represented by silicone rubber which is a kind of thermosetting elastomer can be preferably used. . Moreover, when manufacturing the elastic sealing material 12 with a thermoplastic elastomer, a styrene-type elastomer, an olefin-type elastomer, and a urethane-type elastomer can be used suitably, for example. An inorganic filler or an organic filler may be dispersed in the elastic sealing material 12.

  In the first embodiment, the elastic sealing material 12 exposes one end surface of the frame body 11, but covers the other surface of the frame body 11 and the opening surface of the frame body 11. The opening surface covering portion 20 that constitutes a part of the elastic sealing material 12 and covers the opening surface of the frame body 11 waterproofs the battery housing portion 4 even if the adhesive layer 9 and the frame body 11 are not sufficiently fixed. Contribute to ensuring. Further, the frame covering portion 30 that constitutes a part of the elastic sealing material 12 and covers the outer surface of the frame 11, the end surface on the groove 6 side, and the inner surface fills the space between the groove 6 and the frame 11, This contributes to waterproofing of the battery housing part 4 located inside the groove 6. The frame covering portion 30 preferably includes ribs 31 protruding outward on the outer surface of the frame 11. The rib 31 effectively contributes to waterproofing at the outer side of the inner surface of the groove 6.

  As described above, the waterproof member 10 is formed by integrating the frame body 11 and the elastic seal material 12 formed continuously from the opening surface of the frame body 11 to the surface of the frame body 11. Since the opening surface covering portion 20 is composed of the elastic sealing material 12, it can be formed extremely thin. For example, as in the past, a resin tray is molded, a sealing member is attached to the protruding surface of the tray to form a waterproof member, and the waterproof member is fixed to the cover body 8 via the adhesive layer 9. In some cases, the thickness of the bottom plate portion of the tray has a limit in molding, and can be as thin as 0.4 mm at the thinnest. Similarly, even if the thickness of the cover body 8 (thickness t1 in FIG. 4) is the thinnest and 0.4 mm in thickness, the adhesive layer 9 of about 0.05 mm is added to the tray from the outer surface of the cover body 8. It is the limit to reduce the total thickness up to the inner surface of the sheet to 0.85 mm (the total of the cover body 8 thickness 0.4 mm + the adhesive layer 9 thickness 0.05 mm + the tray bottom plate thickness 0.4 mm). . On the other hand, in the first embodiment, since the thickness of the opening surface covering portion 20 (thickness t2 in FIG. 5) can be reduced to about 0.15 mm, the opening surface of the waterproof member 10 from the outer surface of the cover body 8. The total thickness up to the inner surface of the cover 20 is reduced to 0.6 mm (the total of the cover body 8 thickness 0.4 mm + adhesive layer 9 thickness 0.05 mm + opening surface cover 20 thickness 0.15 mm). Can do. For this reason, even if the waterproof member 10 is separated from the cover main body 8, the electronic device 1 can be thinned. In addition, since the cover body 8 and the frame body 11 are not integrally molded, the cover body 8 is not subjected to a thermal or pressure load on the cover body 8 side in the process of attaching the elastic sealing material 12 to the frame body 11. The appearance of the outer surface of the main body 8 is not impaired.

2. Manufacturing method of waterproof cover The above-mentioned waterproof cover 2 can be manufactured in the following manner, for example. Hereinafter, an example in which PC resin is used as the material of the cover main body 8 and the frame body 11 and silicone elastomer is used as the material of the elastic sealing material 12 will be described. First, the cover main body 8 and the frame body 11 are molded by separate molds using PC resin. As the molding method, since the PC resin is a thermoplastic resin, injection molding in which a molten PC resin is injected into a mold and molded can be suitably used. As another molding method, PC resin in a softened state may be set in a mold, and vacuum molding, pressure molding, or vacuum / pressure molding may be performed. After forming the frame body 11, the frame body 11 is set in another mold.

  FIG. 6 shows a partial cross-sectional view of the vicinity of the frame in a state where the frame shown in FIG. 5 is set in a mold for forming an elastic seal material.

  In the first embodiment, the mold for molding the elastic sealing material 12 is composed of a first mold 13, a second mold 14 and a third mold 15. However, the mold for molding the elastic sealing material 12 is not limited to the configuration of these three molds, and may be configured of two or four or more molds. A gap V between the space formed by the first mold 13, the second mold 14, and the third mold 15 and the frame body 11 set in the space is a region where the elastic sealing material 12 is formed. . The unvulcanized silicone elastomer composition is supplied from the elastomer supply hole 16 formed in the first mold 13 in the direction of the arrow in FIG. Next, the first mold 13, the second mold 14, and the third mold 15 are heated to cure the silicone elastomer composition. Finally, the first mold 13, the second mold 14, and the third mold 15 are opened, and the waterproof member 10 in which the elastic sealing material 12 is integrally formed with the frame body 11 is taken out. The above-described manufacturing method is only an example, and can also be applied to manufacturing other embodiments described later.
