Description

  The present invention relates to a power supply device, and more specifically to an emergency power supply device that can be used in an emergency such as a power failure.

  Many products around us function by electricity, which is essential and indispensable in daily life. Therefore, when power transmission from an electric power company is stopped due to a natural disaster such as an earthquake or lightning, a power outage occurs, which is very inconvenient, and in some cases, it is even exposed to life risk.

  Therefore, when a power failure occurs due to an earthquake, lightning, or the like, it is necessary to prepare for obtaining electricity without depending on the supply of electricity from the electric power company.

FIG. 1 is a diagram illustrating an outline of a power supply device according to a first embodiment. FIG. 5 is a schematic view of the inside of a housing of a power supply device according to a second embodiment.

  Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different forms, and is not limited to the examples described in the following embodiments.

  FIG. 1 is a diagram illustrating an outline of a power supply device (hereinafter referred to as “the present power supply device”) 1 according to the present embodiment, and FIG. 2 is a schematic diagram of the inside of a housing 3 of the power supply device 1. As shown in these figures, the power supply device 1 includes a solar panel 2, a caster 31, a solar panel connection port 32, a casing 3 including a DC outlet 33 and an AC outlet 34, a solar panel 2 and a solar panel connection port. 32 to connect the solar panel connection cord 21, the direct current battery 4 housed in the housing 3, and the output of the direct current battery 4 connected to the direct current battery 4 is converted into alternating current and supplied to the outside through the alternating current outlet 34.

  In the power supply device 1, the solar panel 2 is a device that can generate power based on sunlight. The solar panel 2 is not limited as long as it has this function, but a plurality of solar cells are arranged and connected to each other to form a panel. The solar panel 2 is not particularly limited, and a commercially available one can be used. However, the maximum output is 100 W or more so that electric power that can withstand the use of the electric device to be connected can be supplied. Is preferable, and more preferably 150 W or more.

  Moreover, the solar panel 2 is connected to the connection cord 21, and the connection cord 21 is connected to the solar panel connection port 32 of the housing 3, so that electricity can be sent to the DC battery 4 and stored. The connection between the connection cord 21 and the solar panel connection port 32 is not particularly limited, but a connection using a plug and an outlet is a preferable example. In this case, the connection cord 21 side has a plug 211. The solar panel connection port 32 is preferably an outlet. As a result, the solar panel 2 and the housing 3 can be separated from each other, and the solar panel 2 and the housing 3 can be separately disposed and connected and used as necessary, thereby improving convenience.

  In this embodiment, the solar panel 2 side of the connection cord 21 may be directly connected to the solar panel 21, but preferably has a portion that can be separated by a combination of the outlet 213 and the plug 214. By doing in this way, it becomes possible to simplify the structure of the solar panel 21, and the possibility that it will become an obstacle, for example as a foldable structure, becomes remarkably low.

  In the present embodiment, the housing 3 can accommodate the DC battery 4 and the like as described above. The material of the housing 3 is not particularly limited, but is preferably a hard material such as metal.

  In the present embodiment, the shape of the housing 3 is not particularly limited, but preferably has a space 35 inside and can be opened and closed by the open / close door 36.

  In the present embodiment, a caster 31 is attached to the lower part of the housing 3. It can be moved by attaching casters. The casters 31 are not limited, but it is preferable that at least three or more casters 31 are provided on the bottom surface, preferably four in total when the bottom surface of the housing 3 is square.

  Moreover, in this embodiment, it is preferable that the internal space 35 is divided | segmented up and down by the partition plate 37, and it is preferable to arrange | position the DC battery 4 in the space 351 of the lower side. Since the DC battery 4 is generally heavy, it is possible to partition the space 35, arrange other parts such as a monitor device in the upper space 352, and arrange the DC battery 4 in the lower side, with the center of gravity at the lower part of the device. And stable placement becomes possible.

  In this embodiment, the DC battery 4 can store electricity from the solar panel 2. A commercially available battery can be adopted as the DC battery 4 without limitation. The voltage of the DC battery 4 is not limited, but a voltage of about 12 V is generally used, and is particularly preferable because voltage conversion is not required. Further, the DC battery 4 may be one, but a plurality of DC batteries 4 may be electrically connected. In particular, the capacity can be increased by connecting them in parallel.

  In the present embodiment, the DC battery 4 is connected to the solar panel 2, but a solar charge controller 8 is disposed between the DC battery 4 and the solar panel 2, and an input voltage from the solar panel 2. Can be adjusted. As a result, the solar panel 2 is connected to the DC battery 4 via the connection cord 21, the solar panel connection port 32, and the solar charge controller 8.

  In the present embodiment, the solar charge controller 8 is preferably arranged in the upper space 352 in the housing 3 as described above.

  In the present embodiment, the casing 3 is provided with a DC outlet 33. By providing the DC outlet 33, the user can use the appliance by inserting the plug of the appliance driven by the DC power supply into the outlet 33. If the voltage determined by the direct current battery and the direct current outlet 33 is equal, the connection cord is simply connected as it is, but if it is different, a voltage converter may be used.

  In the present embodiment, the AC converter 5 converts a DC voltage output from the DC battery 4 into an AC voltage. As the AC converter 5, a commercially available one can be used. The AC voltage converted by the AC converter is not limited, but is preferably 100 V and the frequency is 50 Hz or 60 Hz. This value is a power source used in a general household, and by setting this value, it becomes possible to use a plug of a general AC appliance as it is. The AC converter 5 is preferably connected between the DC battery 4 and the AC outlet 34. As a result, the DC battery 4 is connected to the AC converter via the connection cord and further connected to the AC outlet 34 via the connection cord. In the present embodiment, it is preferable that the AC converter 5 is also disposed in the space 352 above the housing 3 like the solar charge controller 8.

  In the present embodiment, the DC battery 4 is provided with a monitor device 7 for detecting and displaying the state of the DC battery 4. By providing the monitor device 7, the charge amount and voltage value of the battery at each measurement time can be confirmed. As with the solar charge controller 8, the monitor device 7 is also preferably disposed in the space 352 above the housing 3.

  In the present embodiment, a charger 6 is connected to the DC battery 4. Since the direct current battery 4 causes spontaneous discharge in terms of performance, not only is it separated from the solar panel 2, but even if it is connected to the solar panel and can be charged, it is not fully charged for a long time due to various conditions such as the weather. There can be. When separation from the solar panel lasts for a long time, or even if it is connected to the solar panel, if the amount of spontaneous discharge is less than the amount of charge of the solar panel, there is not enough charge due to discharge even if you want to use it, The appliance may become unusable. Therefore, by connecting the charger 6 to the DC battery 4, it is possible to charge as much as naturally discharged. One of the chargers 6 is connected to the DC battery 4, and the other can be connected to a general outlet such as in a building via a plug. Therefore, as this charger 6, it is preferable that it is a charger which receives supply of the electric power from AC power supply (household power supply), for example. As a result, since the present invention also has an AC charger, 100% performance can be exhibited in an emergency where it is not known when it occurs. On the other hand, when the AC power supply is lost, a solar panel that is stored can be installed to continue to function as a power supply device with a charging function by solar power generation.

  As described above, the power supply apparatus has a structure in which necessary parts such as a direct current battery are accommodated in the casing and can be separated from the solar panel, so that it is very easy to carry. In particular, a caster is provided under the housing for easy movement, and a DC battery can be arranged in the space under the housing, so that the center of gravity can be made lower in the housing, resulting in a very stable construction. Furthermore, a DC battery charger is also provided, so that measures against natural discharge can be taken and electric power can be secured stably at all times. That is, it is possible to provide a power supply device that is more reliable and easy to carry.

  The parts for storing the solar panel connection cord 21 are not limited as long as the function can be realized, and may be a case for storing the connection cord by rounding, but it is a hook. This is a simple and preferred form.

  Further, in the power supply device 1, for example, a cord reel 39 or the like may be disposed without arranging anything on the partition plate 37. By doing in this way, it becomes possible to supply electricity to a more distant place. In this case, it is very useful from the viewpoint of securing a wider space to fix what can be used with an AC converter, a monitor device, a charger and the like to the wall surface of the housing 3. If it does in this way, it can have a function as a storage which can store the apparatus required at the minimum in an emergency in one place.

  Further, the power supply device 1 may accommodate, for example, a lighting device. By storing the lighting device in this way, it is possible to ensure brightness first, which is extremely useful in an emergency. In this case, the lighting device is not limited, but is preferably a low power consumption device such as an LED lamp. Note that the lighting device exemplified in this embodiment includes a foldable tripod and an LED lamp attached to the top of the tripod, and can be driven with a direct current. And the notch part 371 is formed in the partition plate 37 of the housing 3, The illuminating device etc. which were folded in this notch part can be accommodated.

  As described above, the power supply device 1 can also provide a power supply device that is more reliable and easy to carry. In particular, according to the present embodiment, it is possible to secure a space for storing a cord reel and the like, which becomes more practical.

  In addition, in this embodiment, although the example provided with all the components 37, a cord reel, and an illuminating device is shown, each of these can be independently arrange | positioned in the housing 3 and there is none Needless to say, the embodiment may be possible, and of course, the monitor device or the like may be appropriately fixed to the inner wall of the housing 3 in order to secure a space for placing an object on the partition plate. Needless to say.

  The present invention has industrial applicability as an emergency power supply.
