Description

  The present invention relates to an electronic device cover member and a battery lid.

  Recently, the generation of carbon dioxide associated with thermal power generation using fossil fuels and the radiation problems associated with nuclear power generation using nuclear fuels have become more serious. Amorphous, single crystal, or polycrystalline silicon has hitherto been put into practical use as a power generation element for generating power using solar energy. However, a power generation element made of a silicon material has a high manufacturing cost, and the power generation efficiency is extremely low in indoor lighting of about 1000 lux. For this reason, there are increasing examples of using dye-sensitized solar cells that can be manufactured at low cost, particularly in indoor applications. Since the dye-sensitized solar cell can be constituted by transparent resin films on both outer sides in the thickness direction, it can be easily arranged on a curved surface, and the appearance can be maintained when it is arranged. A device including a dye-sensitized solar cell in a display unit of a small electronic device using such characteristics is known (see Patent Document 1).

  By the way, recently, there are more and more opportunities to carry small electronic devices such as mobile phones, portable game devices, and e-books. Accordingly, electronic devices are dropped or brought into contact with something while moving. The opportunity for damage is also increasing. As a method for protecting an electronic device from being dropped or coming into contact with something, it is conceivable to cover the electronic device with a highly cushioned cover or case. For example, there is known a cover for an electronic device that has a shape that opens only the operation surface of the electronic device and covers from the side surface to the back surface, and has improved elasticity of the opening portion to facilitate attachment and detachment of the electronic device (patent) Reference 2). A container and a holder made of a relatively hard material (plastic or metal) having an opening on the operation surface side of a small electronic device typified by a mobile phone are also known (see Patent Document 3).

  However, conventional covers and cases that cover small electronic devices do not have the protective performance and ease of holding electronic devices, and when an electronic device that is covered with a cover or case is dropped. In addition, there is a problem that the electronic device is damaged, the cover or the case itself is damaged, or the electronic device is difficult to hold by using the cover or the case, and the frequency of dropping increases. Moreover, when a solar cell is attached to an electronic device, if a cover or a case is attached from above, there is a problem that the solar cell cannot be exposed on the surface and cannot generate power.

  The present invention has been made to solve such a problem, and is for an electronic device that can protect an electronic device from dropping or colliding and can generate power by photoelectric conversion in a state where the electronic device is covered with a cover. An object is to provide a cover member and a battery lid.

  An electronic device cover member (hereinafter simply referred to as a “cover member”) 1 according to the first embodiment opens the operation surface 5 side of the electronic device 4 and covers the outside of the electronic device 4. A tray 2 that opens at least in the direction of the operation surface 5, and a translucent elastic member 3 that is lower in hardness than the tray 2 and covers at least the surface opposite to the opening-side inner surface of the tray 2.

  As shown in FIGS. 1 and 2, the tray 2 is configured by connecting a bottom plate 10 located on the back side of the electronic device 4 and a side wall 11 extending from the bottom plate 10 toward the outer surface of the electronic device 4. It is a member. The side wall 11 sufficiently covers a pair of side surfaces of the electronic device 4, in this embodiment, both side surfaces on the short side, while the other pair of side surfaces, in this embodiment, both side surfaces on the long side are greatly cut out. Have a shape. The tray 2 has through holes 12, 13, 14, in the bottom plate 10 and the side wall 11 according to the positions of switches, connection ports, camera lenses, and the like, which are examples of external access units provided on the side surface and bottom surface of the electronic device 4. 15. Here, the “external access part” refers to a part that is accessible from either one between the outside of the cover member 1 and the electronic device 4. Access methods include not only direct contact but also light and sound input / output.

  The tray 2 is preferably made of a resin, more preferably a thermoplastic resin, a thermosetting resin, an ultraviolet curable resin, and an electron beam curable resin, and particularly preferably a polycarbonate resin or a polyester. It consists of a series resin or a polyamide series resin. The thickness of the bottom plate 10 and the side wall 11 of the tray 2 can be designed to an appropriate thickness depending on the size, weight, etc. of the electronic device 4. For example, when the thickness of the electronic device 4 is in the range of 8 to 20 mm, the short side is 50 to 200 mm, and the long side is 80 to 300 mm, the bottom plate 10 and the side wall 11 of the resin tray 2 are at the thickest part. It can be designed in the range of 0.4 to 1.4 mm, more preferably 0.4 to 1.0 mm.

  The tray 2 includes one regulation plate 17 that is erected toward the electronic device 4 on one of the two side walls 11 having a cut-out portion on the long side of the electronic device 4. The restriction plate 17 is a part for ensuring the fixation between the tray 2 inside the cover member 1 and the outer surface of the electronic device 4 so that the electronic device 4 does not easily fall off from the cover member 1. The restriction plate 17 may be formed not on the side wall 11 on the long side of the tray 2 but on the short side.

  The elastic member 3 includes a bottom plate 20 positioned on the back side of the electronic device 4, a side wall 21 that covers the outer surface of the electronic device 4 from the bottom plate 20, and an operation surface side that covers the outer edge of the operation surface 5 of the electronic device 4 from the side wall 21. It is a member having a boat shape configured by connecting the outer edge portion 27 to each other. The elastic member 3 is preferably configured from a thermoplastic elastomer, a thermosetting elastomer, or the like, and is particularly preferably configured from, for example, a urethane-based or silicon-based elastomer. When the thickest portions of the bottom plate 10 and the side wall 11 of the tray 2 are in the range of 0.4 to 1.4 mm, and more preferably in the range of 0.4 to 1.0 mm, the bottom plate 20 and the side wall 21 of the elastic member 3 made of the elastomer. Can be designed in the range of 0.4 to 1.4 mm, more preferably in the range of 0.4 to 1.0 mm at the thickest part. The elastic member 3 is formed on the bottom plate 20 and the side wall 21 in accordance with the positions of the switches, connection ports, camera lenses, and the like provided on the side surface and bottom surface of the electronic device 4. , 25, 26. The convex covering portion 28 is preferably formed to be thinner than other portions so that the electronic device 4 can be touched and operated from the cover member 1. The through holes 22, 23, 24, 25, and 26 are portions that are formed so as to be in contact with the electronic device 4 therethrough or allow light to pass therethrough. The size, shape, position, and number of the convex covering portion 28 and the through holes 22, 23, 24, 25, 26 vary depending on the form of the electronic device 4.

  The side wall 21 of the elastic member 3 is formed to be higher than the height of the side wall 11 of the tray 2. The side wall 11 of the tray 2 is a position in contact with the inside of the operation surface side outer edge portion 27 of the elastic member 3 even at the highest position. Thereby, at least the operation surface side outer edge portion 27 becomes a portion not in contact with the tray 2 and can be freely deformed when being attached to or detached from the electronic device 4. The through holes 22, 23, 24, and 25 of the elastic member 3 are formed at substantially the same shape and size at the same positions as the through holes 12, 13, 14, and 15 of the tray 2. The elastic member 3 completely covers each outer side of the bottom plate 10 and the side wall 11 of the tray 2, while exposing a part of the inner side without completely covering the inner side thereof. The elastic member 3 preferably covers part or all of at least one of the inner peripheral surfaces of the through holes 12, 13, 14, 15 of the tray 2. However, the inner peripheral surfaces of the through holes 12, 13, 14, 15 may not be covered with the elastic member 3.

  As shown in FIGS. 1-3, the elastic member 3 arrange | positions the dye-sensitized solar cell element 30 in the inner side. More specifically, the tray 2 is provided with an opening 18 that is recessed toward the elastic member 3 that covers the outside thereof, and the dye-sensitized solar cell element 30 is disposed therein. Since the outer surface of the dye-sensitized solar cell element 30 is covered with at least the elastic member 3, it is difficult to break even if the cover member 1 is dropped. In this embodiment, the opening 18 is a through-hole that has a square planar shape and penetrates in the thickness direction of the tray 2. The elastic member 3 covering the outer surface of the dye-sensitized solar cell element 30 has at least a side facing the opening surface of the opening 18 as a light transmitting region. This is because light can be applied to the dye-sensitized solar cell element 30. In this embodiment, the outer surface of the elastic member 30 is covered with the decorative layer 60 except for the surface facing the opening surface of the opening 18. However, the cover member 1 may remain translucent so that the tray 2 can be seen completely without covering the entire outer surface of the elastic member 3 with the decorative layer 60. The opening 18 may be a recess that does not penetrate from the inner surface of the tray 2 to the outer surface. In that case, at least the thin part of the tray 2 existing outside the dye-sensitized solar cell element 30 needs to be translucent. Here, the translucent elastic member 3 is preferably one that ensures light transmissivity in the entire wavelength range, but at least the absorption wavelength of the sensitizing dye used in the dye-sensitized solar cell element 30. It is sufficient if the light in the region can be transmitted.

  Moreover, it is preferable that the tray 2 is provided with the film 40 which covers the dye-sensitized solar cell element 30 arrange | positioned in the opening part 18 inside. The film 40 preferably closes the opening 18 and is detachably or non-detachably fixed to the tray 2 via an adhesive layer or the like. When the film 40 is used, it is possible to prevent the dye-sensitized solar cell element 30 from being easily removed from the opening 18. As the material of the film 40, the same material as that of the tray 2 or the elastic member 3 can be suitably used.

  The tray 2 has a connection portion 50 that can be electrically connected to the electronic device 4 on the inner surface of the bottom plate 10, and a conductive wire 51 that electrically connects the connection portion 50 and the dye-sensitized solar cell element 30. , 52. The connection portion 50 is erected on the inner surface of the bottom plate 10 and is configured to be easily connected to a connection recess (not shown) on the electronic device 4 side when the electronic device 4 is attached to the cover member 1. The connection portion 50 preferably has, for example, a form of a coaxial connection plug and can be plugged into a plug connection port which is an example of a connection recess on the electronic device 4 side. It is not limited. Further, the connecting portion 50 is not limited to the bottom plate 10 of the tray 2 and may be disposed on the side wall 11. The conducting wires 51 and 52 may be thin films formed by coating the tray 2 with a metal having excellent conductivity, in addition to the lead wires covering the outer periphery of the thin copper wires with resin. When the metal parts of the conducting wires 51 and 52 are exposed on the surface, the conducting wires 51 and 52 are preferably covered with the film 40. This is because it is necessary to prevent leakage and to prevent the conductors 51 and 52 from being damaged and disconnected. It is preferable that the film 40 is as thin as possible so as not to hinder the attachment of the electronic device 4 to the cover member 1 and the protrusion from the inner surface of the tray 2 is reduced. In addition, it is preferable to make the thickness of the tray 2 larger than the thickness of the dye-sensitized solar cell element 30 so that the dye-sensitized solar cell element 30 does not protrude from the opening 18.

  The cover member 1 according to this embodiment also functions as a battery lid 1 ′ when attached to the electronic device 4 with the secondary battery inserted in the electronic device 4. For this reason, in addition to the cover member 1, the electronic device 4 does not require another lid for preventing the secondary battery from dropping off. However, it is not essential that the cover member 1 also serves as the battery lid 1 '. The electronic device 4 may be provided with a dedicated battery lid, and the cover member 1 may be attached from above. The point that the cover member 1 can also serve as the battery lid 1 ′ is the same in the following embodiments.

  FIG. 7 shows a schematic cross-sectional view of the dye-sensitized solar cell element in FIG.

  The dye-sensitized solar cell element 30 may have any integrated structure, but an example is a so-called W-type integrated structure shown in FIG. The dye-sensitized solar cell element 30 shown in FIG. 7 has a structure that realizes a W-shaped series connection between a transparent resin substrate 70 and a transparent resin substrate 71 in a sectional view. The resin substrates 70 and 71 are provided with a plurality of transparent conductive films 75 made of ITO or the like on their back surfaces. The transparent conductive film 75 on the resin substrate 70 side and the transparent conductive film 75 on the resin substrate 71 side are arranged so that the gaps are staggered. On the inner side of the transparent conductive film 75, an electrolyte layer 80 made of an electrolyte and a porous titanium oxide layer 81 adsorbing a dye (referred to as “dye adsorption / porous titanium oxide layer”) 81 are stacked. Between the resin substrates 70 and 71, the laminate in which the electrolyte layer 80 is laminated on the dye adsorption / porous titanium oxide layer 81 from the left side to the right side in FIG. 7, and the dye adsorption on the electrolyte layer 80 -The laminated body of the reverse layer form which laminated | stacked the porous titanium oxide layer 81 is arrange | positioned in order. The dye-sensitized solar cell element 30 includes a sealing layer 85 on the outer periphery of the side surface, and prevents leakage of the electrolyte from the electrolyte layer 80. However, when a solid electrolyte is used as the electrolyte layer 80, the sealing layer 85 may not be provided. The dye adsorption / porous titanium oxide layer 81 is a layer in which a dye such as a Ru metal complex dye is adsorbed on the surface of titanium oxide fine particles and chemically bonded by a dehydration reaction between the carboxyl group of the dye and titanium oxide. On the other hand, the electrolyte layer 80 is a layer made of an iodine-based electrolyte, for example. When light is absorbed by the dye in the dye adsorbing / porous titanium oxide layer 81 through the resin substrate 70 or the resin substrate 71, electrons in the dye are excited, and the electrons enter the conductor of titanium oxide and become transparent conductive. It moves outside through the film 75. The oxidized dye receives electrons from the electrolyte layer 80 and returns to the ground state. The electrolyte layer 80 oxidized by the dye receives electrons from the transparent conductive film 75 in contact therewith and returns to its original state. By such an oxidation / reduction reaction, when a load circuit is connected between the conducting wire 51 and the conducting wire 52, the electrons move along the dotted path in FIG. The integrated structure of the dye-sensitized solar cell element 30 may be a Z-type integrated structure or a monolithic integrated structure other than the W-type integrated structure.

  FIG. 8 is a schematic view of a situation where power is supplied from the electronic device cover member to the electronic device in a state where the electronic device is attached to the electronic device cover member shown in FIG.

  The electronic device 4 includes a secondary battery 91 and an electronic device side load circuit 92 that is electrically connected thereto. When the cover member 1 is attached to the electronic device 4 and the electronic device 4 and the dye-sensitized solar cell element 30 of the cover member 1 are electrically connected via the connection portion 50, the lead wire 51 extends from the dye-sensitized solar cell element 30. , 52 can supply power to the secondary battery 91. As a result, the electronic device 4 can supply power from the secondary battery 91 to the electronic device side load circuit 92.

(2) Manufacturing method of cover member for electronic device The tray 2 is formed by, for example, an injection molding method in which a molten resin is injected into a mold and molding, or a molding method in which a softened plate-shaped resin is clamped in the mold. Can be suitably manufactured. In the case of the latter molding method, a method of reducing the pressure from one mold side, a method of supplying high-pressure gas from the one mold side, or a method of combining the pressure reduction and the air supply may be used. For example, the elastic member 3 sets the molded tray 2 in a mold, supplies a composition capable of forming the elastic member 3 to the gap between the mold and the tray 2, and crosslinks the composition. It can be formed by a method. When such a molding method is used, the tray 2 and the elastic member 3 can be easily integrated. In order to improve the adhesion between the tray 2 and the elastic member 3, the elastic member 3 is configured by applying a primer to the adhesion region between the molded tray 2 and the elastic member 3 and then setting the primer. The composition may be supplied into the mold. After the tray 2 and the elastic member 3 are integrated, conductive wires 51 and 52 are formed on the inner surface of the tray 2 from the opening 18 formed on the inner surface of the bottom plate 10 of the tray 2, and are electrically connected thereto. The connecting portion 50 is attached to the inner surface of the tray 2. Next, the dye-sensitized solar cell element 30 is put in the opening 18, and the film 40 is stuck thereon.

  When it is necessary to color or decorate the tray 2, the tray 2 is dipped in the paint and the paint is applied by spraying and printing prior to the integral molding of the tray 2 and the elastic member 3, or A decorative sheet may be attached. Note that the tray 2 may be formed after the pigment is kneaded in advance in the molten resin. In addition, if it is necessary to decorate the outer surface of the elastic member 3 and a surface other than the region directly above the opening 18, a paint is applied to the surface by spraying after integral molding with the tray 2. , Printed or a decorative sheet may be attached.
