Background

In recent years, there has been an increasing demand for a portable environment power generation device that generates power by the external environment so that a user can supply power to a load of a portable electronic device such as a smartphone, a notebook PC (Personal Computer), or a tablet PC even when the user is out of a home where a commercial power supply is not available. Examples of such an environmental power generation device include a device having a solar cell that generates power using light energy such as sunlight, and a device having a thermoelectric conversion element that generates power using heat energy such as geothermal heat.

As such an environmental power generation device, for example, patent document 1 discloses a sheet-like solar cell which can be bent to improve transportability and storage property.

Disclosure of Invention

Problems to be solved by the invention

However, in the invention described in patent document 1, since the solar sheet cells are modularized in a state in which they cannot be attached to and detached from each other, the number of solar cell units to be used cannot be adjusted according to the usage situation, a part of the solar cells cannot be replaced in the event of a failure, and individual solar sheet cells cannot be connected to another device as needed.

In contrast, patent document 2 discloses a battery charger in which a solar battery can be engaged with a wiring by a hook.

However, in the invention described in patent document 2, since the surface direction of the solar cell is different from the attaching and detaching direction of the solar cell, the solar cell is easily damaged by bending stress or the like at the time of attaching and detaching the solar cell, and it takes time to attach and detach the solar cell with high reliability.

Accordingly, an object of the present invention is to solve the above problems and to provide a power wiring device having improved portability and/or convenience.

With this configuration, since the external circuit element mounted with the environmental power generation element can be carried while being mounted on the wiring member, the power wiring device can be easily moved to a position where the power generation efficiency is high, and a decrease in the power generation efficiency due to the external environment can be suppressed.

In the power wiring device according to the present invention, preferably, in the above configuration, the wiring member is a member having flexibility. With such a configuration, the power wiring device can be deformed to be easily stored and transported.

In the above configuration, the power wiring device of the present invention is preferably configured such that the wiring member includes: an edge holding member that holds the external circuit element on the wiring member by restricting a displacement of the external circuit element in a thickness direction at an edge portion of the external circuit element. With this configuration, since the external circuit element can be held without being separated from the wiring member, even when the power wiring device is carried in a state where the external circuit element is mounted on the wiring member, the external circuit element can be prevented from being detached from the wiring member and deformed, or from being damaged by application of an excessive stress.

In the power wiring device according to the present invention, preferably, in the above configuration, the edge holding member has a receiving portion that receives the edge in an insertion and extraction direction of the second connector, and the second connector is positioned so as to be attachable to the first connector by receiving the edge in the receiving portion in a state where the second connector is opposed to the first connector. With this configuration, the external circuit element can be moved parallel to the wiring member, and the second connector can be easily attached to the first connector. Further, stress applied to each member when the second connector is attached to the first connector can be reduced.

In the power wiring device according to the present invention, preferably, in the above configuration, the external circuit element includes a load element as a circuit element capable of consuming the power input from the second connector. With this configuration, the power generated by the environmental power generation element provided in the power wiring device can be easily consumed by the load element. Further, the load element and the environmental power generation element can be easily transported as a single unit while maintaining the arrangement during use or the arrangement after use. Further, since the connector can be attached and detached, the arrangement can be freely changed.

In the above configuration, the wiring member preferably includes a plurality of wiring member units, the plurality of wiring member units include the first connector, and the plurality of wiring member units are mechanically and electrically connected to each other via a connecting wiring member. With this configuration, the power wiring device can be folded in the region where the wiring members are connected, and therefore can be easily stored and transported.

In the above configuration, the connection wiring member preferably includes fourth connectors disposed on the plurality of wiring member units, and the plurality of wiring member units are mechanically and electrically connected to each other by the fourth connectors being connected directly or via another member. With this configuration, since the power wiring device can be added in units of wiring member units, the size of the entire power wiring device can be freely adjusted according to the use situation of the user.

In the power wiring device according to the present invention, preferably, in the above configuration, the wiring member is bendable at a bending position where the external circuit element is not disposed. With this configuration, the power wiring device can be folded with the external circuit element attached thereto, and thus the portability of the power wiring device can be improved.

In the power wiring device according to the present invention, preferably, in the above configuration, the two first connectors adjacent to the bending position are arranged at in-plane positions where the wiring members do not overlap each other in the plane direction when the wiring members are bent at the bending position. With this configuration, the thickness in the overlapping direction when the power wiring device is folded can be reduced, and thus the portability of the power wiring device can be further improved.

Detailed Description

Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The same reference numerals are given to the common structural elements in the drawings.

[ Structure of Power Wiring device 1 ]

Fig. 1A and 1B are schematic views (rear view and plan view) of a power wiring device 1 according to an embodiment of the present invention. As shown in fig. 1B, the power wiring device 1 has a wiring member 10 and an external circuit element 20. As shown in fig. 1A and 1B, the wiring member 10 is formed in a plate shape and a planar shape and has a plurality of first connectors 12. The power wiring device 1 includes at least one environment power generating element in at least any one of the external circuit elements 20. The external circuit element 20 is formed in a plate shape, and includes a second connector 21 that is mechanically and electrically detachable from any first connector 12 among the plurality of first connectors 12 included in the wiring member 10. The plurality of first connectors 12 are electrically connected to each other through the conductive portions 11B, and the external circuit elements 20 mounted on the plurality of first connectors 12 are electrically connected to each other through the conductive portions 11B. In fig. 1A and 1B, for convenience of explanation, the shapes of the respective components of the power wiring device 1 are defined, and the shapes of the respective components are not limited to these shapes. This is also the same in the following figures.

In the present embodiment, the surface direction of the wiring member 10 and the external circuit element 20 is a direction parallel to the paper surface of fig. 1B, and the thickness direction of the wiring member 10 and the external circuit element 20 is a direction perpendicular to the paper surface of fig. 1B. The upper surfaces of the wiring member 10 and the external circuit element 20 are visible in a plan view as shown in fig. 1B. That is, the first connector 12 and the edge holding member 14A are provided on the upper surface of the wiring member 10. The left-right direction of the wiring member 10 and the external circuit element 20 is the left-right direction in fig. 1B.

As shown in fig. 1B, the wiring member 10 has: a substrate main body 11A formed of an insulating material, two first connectors 12, a conductive portion 11B for electrically connecting the first connectors 12, an edge holding member 14A for holding an edge of an external circuit element 20, and a third connector 13. The wiring member 10 according to the present embodiment is a planar member having a rectangular shape in a plan view. The wiring member 10 may have a covering portion formed of an insulating material that covers the periphery of the conductive portion 11B. The wiring member 10 may be formed of a substrate having wiring as the conductive portion 11B, for example, a rigid substrate such as an epoxy glass substrate or a phenol paper substrate, or a Flexible printed circuit board (Flexible printedcuicts) having flexibility and formed of a polyimide film or the like. When a flexible printed circuit board is used as the wiring member 10, it is preferable to provide a reinforcing plate in a region where electronic components, edge holding members 14A to 14E described later, and the like are mounted to ensure the rigidity of the board main body 11A. When a rigid substrate or a flexible substrate is used as the wiring member 10, it is preferable to cover the surface with a covering material such as cloth or resin from the viewpoint of design and environmental resistance.

The conductive portion 11B can be energized along the extending direction. The conductive portion 11B includes a conductor. The conductor included in the conductive portion 11B is not particularly limited, and examples thereof include a conductor formed of a metal material such as copper, aluminum, gold, silver, nickel, and iron, and an alloy material containing these metal materials. The conductive portion 11B may have flexibility that enables repeated bending at an arbitrary position along the extending direction, or may have rigidity. From the viewpoint of improving the degree of freedom in installation of the entire power wiring device 1 by changing the shape of the wiring member 10, the conductive portion 11B is preferably flexible.

Two first connectors 12 are connected to the conductive portions 11B, respectively. Therefore, the two first connectors 12 are electrically connected to each other through the conductive portions 11B. In the present embodiment, the two first connectors 12 are arranged so as to be separated from each other along the longitudinal direction of the wiring member 10 (the left-right direction in fig. 1B). As shown in fig. 1B, the wiring member 10 may be provided with a third connector 13 at the edge portion. In the case where the wiring member 10 is provided with the third connector 13, the two first connectors 12 are electrically connected to the third connector 13 through the conductive portions 11B.

Although fig. 1A and 1B show an example in which the wiring member 10 has two first connectors 12, the wiring member 10 may have a plurality of first connectors 12. That is, the wiring member 10 may have three or more first connectors 12. In this case, the plurality of first connectors 12 are in conduction with each other. The plurality of first connectors 12 may be arranged so as to be spaced apart from each other along the longitudinal direction of the wiring member 10, but is not limited to this embodiment. The plurality of first connectors may be, for example, the same shape as each other.

As shown in fig. 1B, an edge holding member 14A is provided in a region of the wiring member 10 surrounding the external circuit element 20 in a plan view. The edge holding member 14A has a receiving portion 15A that receives an edge of the external circuit element 20 along an insertion/removal direction (shown by an arrow in fig. 1B) of the second connector 21. As shown in fig. 1A, the housing portion 15A is configured to cover the upper surface and the side surface of the edge portion in the left-right direction of the external circuit element 20. Thus, when the edge portion in the left-right direction of the external circuit element 20 is housed in the housing portion 15A in a state where the second connector 21 is opposed to the first connector 12 in a plan view, the upper surface of the edge portion of the external circuit element 20 abuts against the edge holding member 14A to regulate the displacement in the thickness direction of the external circuit element 20. Further, the left-right direction side surface of the external circuit element 20 abuts on the edge holding member 14A, whereby the left-right direction position of the external circuit element 20 with respect to the edge holding member 14A is positioned. Thereby, the second connector 21 is positioned so as to be mountable to the first connector 12. In addition, the receiving portion 15A of the left edge holding member 14A in fig. 1B shows a state in which the edge portion having received the external circuit element 20 is already received and the second connector 21 is attached to the first connector 12.

In the example shown in fig. 1A and 1B, the receiving portion 15A extends not only in the region of the edge portion in the left-right direction of the external circuit element 20 but also in the region of the edge portion adjacent to the left and right of the first connector 12 and the region of the edge portion of the external circuit element 20 facing the first connector 12. Therefore, the rectangular external circuit element 20 can be accommodated in the accommodating portion 15A at all of the four edge portions thereof. However, with respect to the receiving portion 15A (the upper side of fig. 1B, that is, the receiving portion 15A on the side facing the first connector 12) which becomes the insertion side when the external circuit element 20 is inserted into the edge holding member 14A, the external circuit element 20 is not restricted in the plane direction, and the external circuit element 20 can be inserted into the edge holding member 14A from the side facing the first connector 12 of fig. 1B. As shown in fig. 1B, a rectangular opening 14A1 is formed at the center in the plane direction of the edge holding member 14A. When a solar cell as an environmental power generation element is mounted on the external circuit element 20, sunlight can be incident on the solar cell through the opening 14a1 to generate power.

In this manner, the housing portion 15A reliably restricts displacement of the external circuit element 20 in the thickness direction by housing all of the four edge portions of the external circuit element 20 having a rectangular shape in plan view. Therefore, even when the power wiring device 1 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 can be stably held in a parallel state so as not to be separated from the upper surface of the wiring member 10. Further, since the left-right direction side surface of the external circuit element 20 abuts on the edge holding member 14A, the left-right direction position of the external circuit element 20 with respect to the edge holding member 14A is positioned, the second connector 21 can be positioned so as to be attachable to the first connector 12. As described above, by housing the edge portion of the external circuit element 20 in the housing portion 15A of the edge holding member 14A, the external circuit element 20 can be moved parallel to the wiring member 10, and the second connector 21 can be easily attached to the first connector 12. Further, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In the present embodiment, the external shape of the external circuit element 20 is a rectangular shape in plan view, but the external shape is not limited to this embodiment. The external circuit element 20 may be formed in a straight line shape at least in a part of the edge portion in the left-right direction. By housing the straight portions in the edge holding member 14A, the second connector 21 can be positioned and attached to the first connector 12 while the external circuit element 20 is kept parallel to the wiring member 10. In addition, when only the function of restricting the displacement of the external circuit element 20 in the thickness direction with respect to the wiring member 10 is obtained, the external shape of the external circuit element 20 does not need to have a straight line portion at the edge portion, and may have a shape formed only by a curved line such as a circular shape. The shape of the receiving portion 15A of the edge holding member 14A may be a shape having an appropriate curve corresponding to the shape of the edge of the external circuit element 20.

In addition, the region of the wiring member 10 on which the external circuit element 20 is placed does not necessarily have to be provided with the wiring member 10 (substrate main body 11A) over the entire surface, and the wiring member 10 (substrate main body 11A) may be provided only in a portion for supporting the external circuit element 20, for example, a portion in contact with the peripheral edge portion of the external circuit element 20, for the purpose of reducing the weight.

As shown in fig. 1B, the external circuit element 20 has a second connector 21. Fig. 1B shows the following state: the second connector 21 of the external circuit element 20 is already mounted on the first connector 12 on the left side, and a state is desired in which the second connector 21 of the external circuit element 20 is mounted on the first connector 12 on the right side. In the example shown in fig. 1B, the second connector 21 is provided at an edge portion of the external circuit element 20. This embodiment is preferable because it can suppress excessive stress such as bending stress from being applied during insertion and removal when the center position in the thickness direction of the portion of the second connector 21 that contacts the first connector 12 substantially coincides with the center position in the thickness direction of the edge portion of the external circuit element 20 where the second connector 21 is disposed. In the present embodiment, the insertion and removal direction of the second connector 21 with respect to the first connector 12 is the vertical direction in fig. 1B, and is parallel to the surface direction of the external circuit element 20. This prevents the external circuit element 20 from protruding in the thickness direction when the external circuit element 20 is attached and detached, and the thickness of the power wiring device 1 can be reduced in consideration of the attachment and detachment of the external circuit element 20. Further, when the external circuit element 20 is attached and detached, a force may be applied in the surface direction of the external circuit element 20, and it is possible to suppress application of an excessive stress such as a bending stress to each member. In the example of fig. 1B, the insertion/removal direction of the second connector 21 with respect to the first connector 12 is also parallel to the surface direction of the wiring member 10.

The external circuit element 20 can have, for example, an environmental power generating element. The environment power generation element is capable of outputting power generated by environment power generation from the second connector 21. In the case where the wiring member 10 mounts a plurality of external circuit elements 20 having environment power generating elements, the respective power generating capacities of the plurality of environment power generating elements may be different from each other.

In the present embodiment, at least one external circuit element 20 has an environment power generating element among the two external circuit elements 20 connected to the two first connectors 12 of fig. 1B. This enables the power generated by the environmental power generation to be output from the second connector 21, and the power can be supplied to the load element connected to the wiring member 10.

The second connector 21 is mechanically and electrically attachable to and detachable from any of the first connectors 12 of the wiring member 10. Here, in the present specification, the two connectors are "mechanically and electrically detachable" in the sense that one connector can be attached to the other connector and also can be detached from the attached state. In a state where one connector is mounted on the other connector, the two connectors are mechanically and electrically connected to each other. Further, in a state where one connector is detached from the other connector, the two connectors are not mechanically and electrically connected to each other.

The environment power generating element mounted on the external circuit element 20 may be configured to include, for example, a reverse current prevention unit not shown and an environment power generating unit capable of generating electric power by environment power generation. In this case, the environment power generation unit is a device that generates power according to an external environment, and includes, for example, a solar cell that generates power using light energy such as sunlight or indoor light. Alternatively, the environment power generation unit may have a thermoelectric conversion element that generates power using heat energy such as geothermal heat. The environment power generation unit outputs the generated electric power to the second connector 21 via the reverse current prevention unit.

The types of solar cells that can be mounted as the environmental power generation element are roughly classified into inorganic solar cells using an inorganic material and organic solar cells using an organic material. Examples of the inorganic solar cell include Si-based cells using silicon (Si) and compound-based cells using a compound. Examples of the organic solar cell include a low-molecular-weight vapor deposition system using an organic pigment, a thin-film system such as a polymer coating system using a conductive polymer and a coating conversion system using a conversion semiconductor, and a dye-sensitized system including titanium dioxide, an organic dye, and an electrolyte. In addition, the solar cell included in the solar cell panel may include an organic-inorganic hybrid solar cell, or a solar cell using a perovskite compound. In this case, the dye-sensitized solar cell is preferably formed as a plastic film or the like, from the viewpoint of easy molding into a thin shape. When the solar cell panel is in the form of a thin panel, the solar cell panel is not limited to the solar cell made of the plastic film or the like, and any form may be used as long as the solar cell panel is thin. When the solar cell panel is a thin panel, the thickness is preferably 10 μm or more and 3mm or less, for example, from the viewpoint of manufacturing technology.

The reverse current prevention section suppresses the current from the second connector 21 from flowing into the environment power generation section. The reverse current prevention unit may include a circuit element such as a diode. When a diode is used as the reverse current prevention unit, the anode is connected to the environment power generation unit side and the cathode is connected to the second connector 21 side. The reverse current prevention unit may be configured such that a collector and a base terminal of the transistor are connected and a diode is used between the counter emitter and the collector.

Further, the environment power generating section may be an environment power generating section included in another circuit element connected via the external circuit element 20.

The external circuit element 20 may be provided with a load element in addition to the environmental power generating element instead of the environmental power generating element. The load element can consume the electric power input from the second connector 21. In fig. 1B, among the two external circuit elements 20 mounted via the two first connectors 12, one external circuit element 20 may have an environment power generating element and the other external circuit element 20 may have a load element. Further, at least one external circuit element 20 may include an environmental power generating element and a load element. In order to supplement the electric power from the environmental power generation element, the external circuit element 20 may have a charged secondary battery element described later, or may be configured to supply auxiliary electric power from another device to the load element via the third connector 13. When the external circuit element 20 includes a plurality of load elements, the plurality of load elements may have different power consumptions.

When the external circuit element 20 is mounted with a load element, the external circuit element 20 may include a load and a voltage control unit in addition to the second connector 21. The second connector 21 and the voltage control section are electrically connected to each other via a power wiring or directly. Further, the voltage control section and the load are electrically connected to each other via an electric wiring or directly.

The load is an arbitrary load that can consume electric power. The load is, for example, an electronic device such as a radio and a speaker, an LED lighting, an electric toy, or the like. The power consumed by the load varies depending on the driving state of the load, and the like.

The voltage control unit controls the power input from the second connector 21 to a predetermined voltage and outputs the power to the load. Specifically, the voltage control unit steps down or up the power input from the second connector 21 to a predetermined voltage suitable for driving the load, such as a rated voltage of the load, and outputs the stepped-down or stepped-up power to the load.

The load may be a load included in another circuit element connected via the external circuit element 20, and may be a general electronic device such as a smartphone, a mobile phone, and a personal computer.

The power wiring device 1 may further have a secondary battery element as a circuit element. When the external circuit element 20 includes a secondary battery element, the external circuit element 20 may include, for example, a secondary battery, a switching unit, a voltage control unit, and a reverse current prevention unit in addition to the second connector 21.

The secondary battery is a chargeable and dischargeable secondary battery. Examples of the secondary battery include a lithium ion battery and a nickel hydride battery.

The switching portion is capable of switching a charging state of charging the secondary battery with the electric power input from the second connector 21 and a feeding state of outputting the electric power from the secondary battery from the second connector 21. The switching unit includes, for example, switching elements electrically connected to the second connector 21 and the secondary battery, respectively.

The voltage control unit controls the electric power input from the second connector 21 to a predetermined voltage and outputs the electric power to the secondary battery. Specifically, the voltage control unit steps down or up the electric power input from the second connector 21 to a predetermined voltage suitable for charging the secondary battery, such as a rated voltage of the secondary battery, and outputs the resultant voltage to the secondary battery. The voltage control unit controls the electric power input from the secondary battery to a predetermined voltage and outputs the voltage to the second connector 21. Specifically, the voltage control unit boosts or lowers the electric power input from the secondary battery to a predetermined voltage suitable for circuit elements such as other load elements, and outputs the resultant voltage to the second connector 21.

When the switching unit is in the power supply state, the reverse current prevention unit suppresses the current from the second connector 21 from flowing into the secondary battery. The reverse current prevention unit may include a circuit element such as a diode. When a diode is used as the reverse current prevention unit, the anode is connected to the secondary battery side and the cathode is connected to the second connector 21 side.

As described above, by providing the external circuit element 20 with the secondary battery element, for example, the secondary battery element is set to the power supply state when the power supply to the load element is insufficient, and the secondary battery element is set to the charge state when the power supply to the load element is sufficient, and the charge state and the power supply state of the secondary battery element are switched depending on the situation, it is possible to stably supply the power to the load element.

The shape of the wiring member 10 is not limited, and may be any shape such as a substantially rectangular shape, a substantially circular shape, or a substantially elliptical shape. Further, when the external circuit elements 20 are arranged in a matrix, as shown in fig. 2, the wiring member 10 may be provided with holes 30 at intersections of longitudinal and transverse bending lines 32 when folded. By disposing the hole 30, it is possible to suppress damage to the wiring member 10 caused by applying a load to the intersection point at the time of folding.

In addition, as shown in fig. 3, in the wiring member 10, the mounting regions 41 for mounting the external circuit elements 20 and the connection regions 43 (connection wiring members) connecting the adjacent mounting regions 41 have distinguishable shapes, and they may be formed as a single member.

In the present embodiment, the wiring member 10 is configured in a planar shape, but the configuration is not limited to this, and the wiring member 10 may not have planarity. Although the wiring member 10 is configured as one member in the example shown in fig. 1A and 1B, the present invention is not limited to this embodiment, and the wiring member 10 may be configured such that a plurality of wiring member units are connected by a connecting wiring member as described below.

[ Structure of Power Wiring device 2 ]

Fig. 4A and 4B are schematic diagrams (rear view and plan view) of the power wiring device 2 according to the embodiment of the present invention. The power wiring device 2 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and has a similar configuration to that of the power wiring device 1 except that the edge holding member 14B is different from the edge holding member 14A of the power wiring device 1. Therefore, the structure of the edge holding member 14B will be described in detail here. Note that, although only one first connector 12 and one edge holding member 14B are illustrated in fig. 4A and 4B, this is for describing the configuration of the edge holding member 14B as a point of difference from the power wiring device 1 in detail, and it should be noted that the power wiring device 2 also includes a plurality of first connectors 12 and edge holding members 14B as in the power wiring device 1. This is also the same for the power wiring devices 3 to 8 shown below.

As shown in fig. 4B, an edge holding member 14B is provided in a region of the wiring member 10 surrounding the external circuit element 20 in a plan view. The edge holding member 14B has a receiving portion 15B that receives an edge of the external circuit element 20 along the insertion/removal direction (vertical direction in fig. 4B) of the second connector 21. As shown in fig. 4A, the housing portion 15B is configured to cover the upper surface and the side surface of the edge portion in the left-right direction of the external circuit element 20. Thus, when the edge portion in the left-right direction of the external circuit element 20 is housed in the housing portion 15B in a state where the second connector 21 is opposed to the first connector 12 in a plan view, the upper surface of the edge portion of the external circuit element 20 abuts against the edge holding member 14B to regulate the displacement in the thickness direction of the external circuit element 20. Further, the left-right direction side surface of the external circuit element 20 abuts on the edge holding member 14B, thereby positioning the left-right direction position of the external circuit element 20 with respect to the edge holding member 14B. Thereby, the second connector 21 is positioned so as to be attachable to the first connector 12. In fig. 4A and 4B, the external circuit element 20 is not drawn, and only the first connector 12 and the edge holding member 14B of the wiring member 10 are drawn.

In the example shown in fig. 4A and 4B, the receiving portion 15B extends not only in the region of the edge portion in the left-right direction of the external circuit element 20 but also in the region adjacent to the left and right of the first connector 12. Therefore, the receiving portion 15B surrounds the external circuit device 20 in all directions except for the side facing the first connector 12, which becomes the insertion port of the external circuit device 20. Therefore, the edge holding member 14B has an コ -shaped shape as a whole surrounding the external circuit element 20 from three directions.

In the edge holding member 14B, the accommodating portion 15B is not formed on the side (upper side in fig. 4B) opposite to the first connector 12, and the external circuit element 20 can be inserted into the edge holding member 14B from the upper side in fig. 4B.

The edge holding member 14B may have guide grooves (not shown) into which the side surfaces of the external circuit element 20 can be inserted, on the left and right side surfaces on the side in contact with the external circuit element 20. This guides the second connector 21 during insertion and removal, facilitates insertion and removal with respect to the first connector 12, and alleviates stress during insertion and removal.

As shown in fig. 4B, an opening 14B1 is formed at the center of the edge holding member 14B. When a solar cell as an environmental power generation element is mounted on the external circuit element 20, sunlight can be incident on the solar cell through the opening 14B1 to generate power.

In this manner, the housing portion 15B houses the edge portions of three sides of the external circuit element 20 having a rectangular shape in plan view, thereby reliably restricting displacement of the external circuit element 20 in the thickness direction. Therefore, even when the power wiring device 2 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 can be stably held in a parallel state so as not to be separated from the upper surface of the wiring member 10. Further, since the left-right direction position of the external circuit element 20 with respect to the edge holding member 14B is positioned by the left-right direction side face of the external circuit element 20 abutting against the edge holding member 14B, the second connector 21 can be positioned so as to be mountable to the first connector 12. As described above, by housing the edge portion of the external circuit element 20 in the housing portion 15B of the edge holding member 14B, the external circuit element 20 can be moved parallel to the wiring member 10, and the second connector 21 can be easily attached to the first connector 12. Further, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In this modification, the edge holding member 14B does not hold the entire edge of the external circuit element 20, as compared with the power wiring device 1, and therefore the power wiring device 2 can be made lightweight in accordance with the portion where the edge holding member 14B is omitted.

[ Structure of Power Wiring device 3 ]

Fig. 5A and 5B are schematic diagrams (rear view and plan view) of the power wiring device 3 according to the embodiment of the present invention. The power wiring device 3 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and has a similar configuration to that of the power wiring device 1 except that the edge holding member 14C is different from the edge holding member 14A of the power wiring device 1. Therefore, the structure of the edge holding member 14C will be described in detail here.

As shown in fig. 5B, an edge holding member 14C is provided in a region of the wiring member 10 surrounding the external circuit element 20 in a plan view. The edge holding member 14C has a receiving portion 15C that receives an edge of the external circuit element 20 along the insertion/removal direction (vertical direction in fig. 5B) of the second connector 21. As shown in fig. 5A, the housing portion 15C is configured to cover the upper surface and the side surface of the edge portion in the left-right direction of the external circuit element 20. Thus, when the edge portion in the left-right direction of the external circuit element 20 is housed in the housing portion 15C in a state where the second connector 21 is opposed to the first connector 12 in a plan view, the upper surface of the edge portion of the external circuit element 20 abuts against the edge holding member 14C to regulate the displacement in the thickness direction of the external circuit element 20. Further, the left-right direction position of the external circuit element 20 with respect to the edge holding member 14C is positioned by the left-right direction side face of the external circuit element 20 abutting against the edge holding member 14C. Thereby, the second connector 21 is positioned so as to be attachable to the first connector 12. As in the power wiring device 2, a guide groove may be provided on the inner side surface of the edge holding member 14C. In fig. 5A and 5B, the external circuit element 20 is not drawn, and only the first connector 12 and the edge holding member 14C of the wiring member 10 are drawn.

As shown in fig. 5B, an opening 14C1 is formed in a region between the pair of left and right edge holding members 14C. When a solar cell as an environmental power generation element is mounted on the external circuit element 20, sunlight can be incident on the solar cell through the opening 14C1 to generate power.

In this manner, the housing portion 15C reliably restricts displacement of the external circuit element 20 in the thickness direction by housing the edge portions of both sides of the external circuit element 20 having a rectangular shape in plan view. Therefore, even when the power wiring device 3 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 can be stably held in a parallel state so as not to be separated from the upper surface of the wiring member 10. Further, since the left-right direction position of the external circuit element 20 with respect to the edge holding member 14C is positioned by the left-right direction side face of the external circuit element 20 abutting against the edge holding member 14C, the second connector 21 can be positioned so as to be mountable to the first connector 12. As described above, by housing the edge portion of the external circuit element 20 in the housing portion 15C of the edge holding member 14C, the external circuit element 20 can be moved parallel to the wiring member 10, and the second connector 21 can be easily attached to the first connector 12. Further, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In addition, in this modification, compared to the power wiring devices 1 and 2, since the edge holding member 14C is configured not to hold the entire edge of the external circuit element 20 but to hold only the edge in the left-right direction, the power wiring device 3 is further reduced in weight corresponding to the portion where the edge holding member 14C is omitted.

[ Structure of Power Wiring device 4 ]

Fig. 6A and 6B are schematic diagrams (rear view and plan view) of the power wiring device 4 according to the embodiment of the present invention. The power wiring device 4 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and is not significantly different from the power wiring device 1 except that the edge holding member 14D is different in structure from the edge holding member 14A of the power wiring device 1. Therefore, the structure of the edge holding member 14D will be described in detail here.

As shown in fig. 6B, an edge holding member 14D is provided in a region of the wiring member 10 surrounding the external circuit element 20 in a plan view. The edge holding member 14D is made of transparent glass or resin, and has a receiving portion 15D for receiving an edge of the external circuit element 20 along the insertion/removal direction of the second connector 21. As shown in fig. 6A, the housing portion 15D is configured to cover the upper surface and the side surface of the edge portion in the left-right direction of the external circuit element 20. Thus, when the edge portion in the left-right direction of the external circuit element 20 is housed in the housing portion 15D in a state where the second connector 21 is opposed to the first connector 12 in a plan view, the upper surface of the edge portion of the external circuit element 20 abuts against the edge holding member 14D to regulate the displacement in the thickness direction of the external circuit element 20. Further, the left-right direction position of the external circuit element 20 with respect to the edge holding member 14D is positioned by the left-right direction side face of the external circuit element 20 abutting against the edge holding member 14D. Thereby, the second connector 21 is positioned so as to be attachable to the first connector 12.

In the example shown in fig. 6A and 6B, the housing portion 15D is configured to cover not only the region of the edge portion in the left-right direction of the external circuit element 20 but also the entire region of the external circuit element 20. In the power wiring device 4, since the edge holding member 14D is formed of a transparent member, it is not necessary to form an opening at the position where sunlight is incident, and the entire external circuit element 20 can be accommodated in the accommodating portion 15D. Therefore, in addition to more reliably restricting the displacement of the external circuit element 20 in the thickness direction, the environmental power generation element and the like included in the external circuit element 20 can be protected from damage, contamination, damage, and the like. Therefore, even when the power wiring device 4 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 and the wiring member 10 can be stably held in a parallel state without being separated from each other, and damage, contamination, breakage, and the like of the environmental power generation element and the like can be suppressed. Further, the second connector 21 can be positioned so as to be attachable to the first connector 12 by positioning the left-right direction position of the external circuit element 20 with respect to the edge holding member 14D by the left-right direction side surface of the external circuit element 20 abutting against the edge holding member 14D. As described above, by housing the edge portion of the external circuit element 20 in the housing portion 15D of the edge holding member 14D, the second connector 21 can be easily attached to the first connector 12 by moving the external circuit element 20 parallel to the wiring member 10. Further, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In the example shown in fig. 6A and 6B, the edge holding member 14D is configured to have a substantially rectangular receiving portion 15D, but the present invention is not limited to this configuration, and the receiving portion 15D may be sized to be substantially immovable inside the external circuit element 20, so that the external circuit element 20 can be positioned.

When the external circuit element 20 includes a solar cell, it is preferable to select glass, or a sheet-like, film-like, or rigid transparent resin having high transparency to sunlight and light resistance, among the transparent members used for the edge holding member 14D of the power wiring device 4. The edge holding member 14D may be formed by combining different materials so that a transparent material is used only at a position where the power generating portion of the solar cell is exposed and an opaque material such as cloth or resin is used around the transparent material. In addition, when sunlight does not need to be transmitted through the edge holding member 14D, various materials such as cloth and resin may be used.

[ Structure of Power Wiring device 5 ]

Fig. 7 is a schematic diagram (plan view) showing the power wiring device 5 according to the embodiment of the present invention. The power wiring device 5 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and has a similar configuration to that of the power wiring device 1 except that the edge holding member 14E is different from the edge holding member 14A of the power wiring device 1. Therefore, the structure of the edge holding member 14E will be described in detail here.

As shown in fig. 7, an edge holding member 14E is provided in a region of the wiring member 10 surrounding the external circuit element 20 in a plan view. The edge holding member 14E used in the power wiring device 5 has substantially the same shape as the edge holding member 14A used in the power wiring device 1, and the edge holding member 14E is configured to be rotatable about a rotation axis using a hinge member or the like. The edge holding member 14E is formed with an engaging portion 17a by a nylon buckle or the like at a position facing the first connector 12. The edge holding member 14E can be fixed to the wiring member 10 side by the locking portion 17a being locked to the locking portion 17b formed on the upper surface of the wiring member 10 side. After the user mounts the second connector 21 of the external circuit element 20 on the first connector 12 on the wiring member 10 side, the user rotates the edge holding member 14E about the rotation axis to lock the locking portion 17a on the edge holding member 14E side to the locking portion 17b on the wiring member 10 side. Thus, similarly to the power wiring device 1, the accommodating portion 15E on the edge holding member 14E side regulates displacement in the thickness direction of the edge of the four sides of the external circuit element 20. Therefore, even when the power wiring device 5 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 can be stably held in a parallel state so as not to be separated from the upper surface of the wiring member 10. Further, in the power wiring device 5, since the work of sliding and inserting the edge portion of the external circuit element 20 in the housing portion 15E is not required, it is possible to suppress the operation of attaching and detaching the external circuit element 20 from being hindered due to friction between the edge portion of the external circuit element 20 and the housing portion 15E.

[ Structure of Power Wiring device 6 ]

Fig. 8 is a schematic diagram showing the power wiring device 6 according to the embodiment of the present invention. The power wiring device 6 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and is configured such that the wiring member 10 includes two wiring member units 10A, and each wiring member unit 10A is mechanically and electrically attachable and detachable by the fourth connector 18, and otherwise is similar to the structure of the power wiring device 1. Therefore, the difference from the power wiring device 1 will be described in detail.

As shown in fig. 8, the wiring member 10 of the power wiring device 6 includes two wiring member units 10A. Each wiring member unit 10A has one first connector 12 and one edge holding member 14A. Two fourth connectors 18 are disposed in each wiring member unit 10A. The fourth connector 18 is a connection wiring member that mechanically and electrically connects the wiring member units 10A to each other. The connecting wiring member is electrically connected to each wiring member unit 10A, and has a boundary between the wiring member units 10A. That is, the connection wiring member is configured as a member different from the wiring member unit 10A. In the wiring member unit 10A, the two fourth connectors 18 and the first connector 12 are electrically connected via the conductive portions. One fourth connector 18 is provided at each end in the left-right direction of each wiring member unit 10A. As shown in fig. 8, when two wiring member units 10A are arranged in the left-right direction, the facing fourth connectors 18 are mechanically and electrically detachable from each other. As illustrated in fig. 8, the above-described structure can be realized by: the fourth connectors 18 are each constituted by a female type connector, and the fourth connectors 18 are connected to each other with a flexible printed board 19 having male type connectors at both ends. In this case, the connection wiring member is constituted by the fourth connector 18 and the flexible printed circuit board 19. Further, the above structure can also be realized by: one of the opposing fourth connectors 18 is configured as a male connector, and the other is configured as a female connector, and both are directly connected. In this case, the connection wiring member is constituted by the pair of fourth connectors 18. The number of the first connectors 12 and the edge holding members 14A included in each wiring member unit 10A is not limited to one, and may be plural. The number of the fourth connectors 18 arranged in each wiring member unit 10A is not limited to two, and one, three, or more may be arranged.

With the above configuration, the power wiring device 6 can be added in units of the wiring member unit 10A, and the size of the entire power wiring device 6 can be freely adjusted according to the use situation of the user or the like. In the configuration of fig. 8 in which the facing fourth connectors 18 are connected to each other by the flexible printed circuit board 19, the power wiring device 6 can be folded in a state in which the wiring member units 10A are connected to each other, and the portability of the power wiring device 6 can be improved.

The number of first connectors 12 provided in each wiring member unit 10A is not limited to one, and two or more first connectors 12 may be provided in each wiring member unit 10A. The arrangement of the fourth connector 18 is not limited to the above-described one, and for example, the fourth connector 18 may be arranged at the end in the vertical direction in fig. 8 in addition to the end in the horizontal direction of the wiring member unit 10A. Thus, the wiring member units 10A can be mechanically and electrically attached and detached in the vertical direction of fig. 8 in addition to the horizontal direction, and therefore the wiring member units 10A can be connected in a matrix form to adjust the size of the power wiring device 6.

The power wiring device 6 is configured to connect the wiring member units 10A to each other via a connection wiring member including the fourth connector 18, but is not limited to this configuration. Each wiring member unit 10A and the connecting wiring member may be integrally configured using, for example, a circuit board in which a rigid substrate portion and a flexible printed substrate portion are integrated. That is, each wiring member unit 10A may be configured by a rigid substrate portion and the connection wiring member may be configured by a flexible printed substrate portion, and the rigid substrate portion and the flexible printed substrate portion may be integrated.

[ Structure of Power Wiring device 7 ]

Fig. 9 is a schematic diagram showing the power wiring device 7 according to the embodiment of the present invention. The power wiring device 7 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and the wiring member 10B has three first connectors 12, and the wiring member 10B is configured to be bendable at a bending position 10B1 at which the external circuit element 20 is not disposed. Otherwise, the structure is similar to that of the power wiring device 1.

More specifically, the wiring member 10B has a rectangular shape elongated in the left-right direction in fig. 9, and three first connectors 12 are arranged at substantially equal intervals in the left-right direction. When the external circuit element 20 is mounted on each first connector 12, a bent position 10b1 extending in the vertical direction is defined at a position between adjacent first connectors 12 where the external circuit element 20 is not disposed. The wiring member 10B can be bent at the bending position 10B1 so that the convex bending and the concave bending alternate.

The structure of the power wiring device 7 can be realized as follows: for example, the wiring member 10B is formed of a flexible printed board, a reinforcing plate is provided in a region where the external circuit element 20 is arranged to secure the rigidity of the wiring member 10B, and no reinforcing plate is provided at the bending position 10B1 to secure the flexibility. Further, the structure of the power wiring device 7 can also be realized by: the flexible printed board portion is disposed at the bending position 10b1 using a circuit board in which a rigid board portion and a flexible printed board portion are integrated. Based on the structure of the power wiring device 7, a region where the external circuit element 20 is not disposed can be bent. Therefore, the power wiring device 7 can be folded in a state where the external circuit element 20 is mounted, and thus the portability of the power wiring device 7 can be improved.

[ Structure of Power Wiring device 8 ]

Fig. 10 is a schematic diagram (perspective view) illustrating the power wiring device 8 according to an embodiment of the present invention. The power wiring device 8 is a modification of the power wiring device 1 shown in fig. 1A and 1B, and four first connectors 12 are arranged in a matrix in the left-right direction of fig. 10, three in the up-down direction, and twelve first connectors 12 are arranged in total on the upper surface of the wiring member 10C. A bent position 10b2 extending in the vertical direction in fig. 10 is defined at an in-plane position between two first connectors 12 adjacent in the horizontal direction where no external circuit element 20 is disposed. In fig. 10, two first connectors 12 adjacent to each other in the left-right direction are in a relationship in which one of the connectors is rotated by 180 degrees about a central axis perpendicular to the planar direction of the wiring member 10C. Therefore, when the user bends the wiring member 10C at the bending position 10b2 so that the male and female bends alternate, the opposing first connectors 12 are separated in the vertical direction of fig. 10 by a length substantially equal to the vertical length of the external circuit element 20, and the first connectors 12 do not overlap each other at all. That is, the two first connectors 12 adjacent to the bent position 10b2 are arranged at in-plane positions where the plane directions do not overlap when the wiring member 10C is bent at the bent position 10b 2. Therefore, the thickness in the overlapping direction when the power wiring device 8 is folded can be reduced, and the portability of the power wiring device 8 can be improved.

The structure of the power wiring device 8 can be realized as follows: for example, the wiring member 10C is formed of a flexible printed board, a reinforcing plate is provided in a region where the external circuit element 20 is arranged to secure the rigidity of the wiring member 10C, and no reinforcing plate is provided at the bending position 10b 2. Further, the structure of the power wiring device 8 can also be realized by: the flexible printed board portion is disposed at the bending position 10b2 using a circuit board in which a rigid board portion and a flexible printed board portion are integrated.

Although fig. 10 shows a case where the substrate is bent one-dimensionally in the column direction, it is naturally possible to bend the substrate two-dimensionally in the row direction and the column direction.

As described above, in the present embodiment, the power wiring device 1 is configured to include: a planar wiring member 10 having a plurality of first connectors 12 and electrically connecting the plurality of first connectors 12 to each other; and a plate-shaped external circuit element 20 which has a second connector 21 mechanically and electrically detachable from any of the first connectors 12 and is mounted on the wiring member 10, wherein the second connector 21 is substantially parallel to the surface direction of the external circuit element 20 with respect to the insertion and extraction direction of the first connector 12, and the external circuit element 20 includes an environment power generating element as a circuit element capable of outputting electric power generated by environment power generation from the second connector 21. With this configuration, the external circuit element 20 mounted with the environment power generation element can be carried in a state of being mounted on the wiring member 10, and thus the power wiring device 1 can be easily moved to a position where the power generation efficiency is high, and a decrease in the power generation efficiency due to the external environment can be suppressed. In particular, in the present embodiment, since the insertion/removal direction of the second connector 21 is substantially parallel to the surface direction of the external circuit element 20, the second connector 21 can be inserted/removed by applying a force in the surface direction of the thin external circuit element 20, and it is possible to make it difficult to apply a bending stress when attaching/detaching the external circuit element 20. Therefore, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In the present embodiment, the wiring member 10 is configured such that: a member having flexibility. With such a configuration, the power wiring device 1 can be deformed to be easily stored and transported.

In the present embodiment, the wiring member 10 is configured such that: the edge holding member 14A is provided for holding the external circuit element 20 on the wiring member 10 by restricting the displacement of the external circuit element 20 in the thickness direction at the edge of the external circuit element 20. With this configuration, since the external circuit element 20 can be held so as not to be separated from the wiring member 10, even when the power wiring device 1 is carried in a state where the external circuit element 20 is mounted on the wiring member 10, the external circuit element 20 can be prevented from being detached from the wiring member 10 and deformed, or from being damaged by application of an excessive stress.

In the present embodiment, the edge holding member 14A is configured to: the second connector 21 can be positioned so as to be attachable to the first connector 12 by having the receiving portion 15A that receives the edge portion along the insertion/removal direction of the second connector 21, and by receiving the edge portion in the receiving portion 15A in a state where the second connector 21 is opposed to the first connector 12. With this configuration, the external circuit element 20 can be moved parallel to the wiring member 10, and the second connector 21 can be easily attached to the first connector 12. Further, stress applied to each member when the second connector 21 is attached to the first connector 12 can be reduced.

In the present embodiment, the external circuit element 20 is configured to: a load element as a circuit element capable of consuming the power input from the second connector 21 is provided. With this configuration, the power generated by the environmental power generation element included in the power wiring device 1 can be easily consumed by the load element.

In the present embodiment, the wiring member 10 is configured such that: there are a plurality of wiring member units 10A, the plurality of wiring member units 10A having first connectors 12, the plurality of wiring member units 10A being mechanically and electrically connected via a linking wiring member. With such a configuration, the power wiring device 6 can be folded in the region where the wiring members are connected, and therefore can be easily stored and transported.

In the present embodiment, the connection wiring member is configured to: the wiring member units 10A are mechanically and electrically connected to each other by having the fourth connectors 18 arranged on the wiring member units 10A and connecting the fourth connectors 18 to each other directly or via another member. With such a configuration, the power wiring device 6 can be added in units of wiring member units 10A, and the size of the entire power wiring device 6 can be freely adjusted according to the use situation of the user or the like.

In the present embodiment, the wiring members 10B and 10C are configured such that: the external circuit element 20 can be bent at an in-plane position where it is not disposed. With such a configuration, the power wiring devices 7 and 8 can be folded in a state where the external circuit element 20 is mounted, and thus the portability of the power wiring devices 7 and 8 can be improved.

In the present embodiment, the two first connectors 12 adjacent to the bending position 10b2 are configured to be arranged at positions in the plane where the wiring member 10C is not overlapped with each other in the plane direction when the wiring member 10C is bent at the bending position 10b 2. With such a configuration, since the thickness in the overlapping direction when the power wiring device 8 is folded can be reduced, the portability of the power wiring device 8 can be further improved.

The present invention has been described based on the drawings and examples, but it should be noted that various changes and modifications based on the present invention are easily made by those skilled in the art. Therefore, it is to be noted that these variations or modifications are included in the scope of the present invention. For example, functions and the like included in each component can be rearranged in a logically inconspicuous manner, and a plurality of components can be combined into one or divided. It is to be understood that they are all included within the scope of the present invention.

For example, the power wiring devices 1 to 8 can be freely combined with each other. For example, the edge holding members 14B to 14E of the power wiring devices 2 to 5 can be replaced with the edge holding member 14A of the power wiring devices 1, 6 to 8 of fig. 1A, 1B, and 8 to 10. In the power wiring devices 7 and 8, the bent positions 10b1 and 10b2 may be configured by the fourth connector 18 and the flexible printed circuit board 19 shown in fig. 8.

The connectors may be combined with each other so as to be detachable from each other, and for example, one connector may be a male connector and the other connector may be a female connector. When the first connector 12 is a male connector, the second connector 21 that can be attached to and detached from the first connector 12 is a female connector. On the other hand, when the first connector 12 is a female connector, the second connector 21 that can be attached to and detached from the first connector 12 is a male connector. When the third connector 13 is a male connector, another connector, not shown, which is detachable from the third connector 13 is a female connector. On the other hand, when the third connector 13 is a female connector, the other connector, not shown, which is detachable from the third connector 13 is a male connector.

The environment power generation module element may not have the reverse current prevention unit. However, if the environment power generation element has the reverse current prevention unit, it is preferable in this respect that the current from the circuit element such as another environment power generation element can be suppressed from flowing into the environment power generation unit or the external environment power generation unit. Further, the environment power generation element may have a voltage control portion that controls the output voltage to be fixed.

As described above, the power wiring devices 1 and 8 according to the present embodiment are mainly miniaturized for carrying a solar cell. Although the power wiring devices 1 to 8 are excellent in portability, it is advantageous to have a plurality of solar cells because the amount of power generated by a single solar cell is small. In addition, in order to suppress the influence on portability due to the increase in the area of the device caused by the presence of the plurality of solar cells, the present embodiment employs a configuration in which the plurality of wiring member units 10A are attached and detached according to the use state of the user, and the wiring member 10 is easily folded.

Industrial applicability

According to the present invention, a power wiring device with improved portability and convenience can be provided.
