  The present invention relates to a power supply device and a power supply unit, and more particularly to a power supply device and a power supply unit that provide an emergency power supply using a battery of a removable electric bicycle.

When a large-scale disaster such as an earthquake or fire occurs, a power failure may occur due to a disconnection or the like, and recovery may not be possible for several days.
When charging of communication equipment such as a mobile phone is not sufficient when such a disaster occurs, it is difficult to contact a family member for a long period of time, making it difficult to confirm safety. In addition, the collection of emergency information, such as radio and lighting, and the securing of the minimum power required for daily life will not remain, and this will lead to inconvenient life for many days.
On the other hand, for disasters that do not know when they occur, it is very burdensome to keep an emergency power supply in terms of both labor and cost.

A power supply device with a reverse power supply function disclosed in Patent Document 1 has been proposed as a power supply that is used for other purposes in normal times and can be diverted as an emergency power supply in the event of a disaster as described above.
The power supply device disclosed in Patent Document 1 charges a battery mounted on an electric vehicle from a system power source in a normal state, and when a power failure occurs on the system power source, power is transmitted from the battery mounted on the electric vehicle to a wireless communication device. Is to supply.

Such a lightweight configuration makes it possible to easily carry the power supply unit to a place where the power supply unit is to be used in an emergency such as a disaster and use it as an emergency power source.

(3) Mounting Method of Battery 20 FIG. 3 is an external perspective view of the power supply unit in the embodiment of the present invention.
FIG. 4 is a front view of the power supply unit.
Next, a procedure for configuring the power supply unit by mounting the battery 20 on the power supply device 10 will be described with reference to FIGS.
As shown in the drawing, a part of the tip of the battery main body 21 protrudes to the side in contact with the power supply device 10, and a protrusion 23 that guides the battery 20 to an appropriate position when the battery 20 is attached to the power supply device 10. Is provided.
The width of the convex portion 23 is provided so as to be substantially the same as the distance between the guide pieces 14a and 14b (provided that the width of the convex portion 23 is slightly shorter).
When the power supply unit is configured, the battery 20 is placed on the holding unit 11 so that the 10 input terminals 12 of the power supply device and the input / output terminal 22 of the battery 20 face each other, and the placed battery 20 is held by the holding unit. 11 is slid in the direction of arrow A in FIG. 2 (length direction), and the input terminal 12 formed in a convex shape is inserted into the input / output terminal 22 of the battery 20 formed in a concave shape. As a result, the terminals 12 and 22 are physically and electrically connected to each other, and the battery 20 is attached and fixed to the power supply device 10.
At this time, the convex portion 23 is sandwiched between the guide pieces 14 a and 14 b of the power supply device 10 and the battery 20 is held on the holding portion 11 so that the battery body 21 is sandwiched between the standing pieces 15 a and 15 b. By sliding, the battery 20 can be guided to an appropriate position on the holding unit 11 and the terminals 12 and 22 can be easily connected.

  As described above, in the present embodiment, the input terminal 12 is mounted and fixed by being inserted into the input / output terminal 22, but the configuration for mounting is not limited to this, and other configurations are possible. It may be fixed by mounting.

Further, in the present embodiment, as described above, the battery main body 21 is sandwiched between the standing pieces 15a and 15b, and the convex portion 23 is inserted between the guide pieces 14a and 14b, whereby the power supply device 10 is configured to guide the battery 20 to an appropriate position on the holding unit 11, but the battery 20 may be guided by other configurations.
For example, a protrusion is provided along the sliding direction on the side of the battery 20 that contacts the holding portion 11, and a groove is provided on the side of the power supply device 10 that contacts the battery 20 so as to match the shape of the protrusion. When configured in this way, the protrusion 20 is inserted into the groove and is slid along the sliding direction, so that the battery 20 is similar to the guide pieces 14a and 14b or the standing pieces 15a and 15b. Can be easily guided to an appropriate position on the holding portion 11.

(4) Method for Supplying Electric Power to Electric Device Next, the operation when the power supply unit supplies electric power to the electric device will be described with reference to FIG.
When both terminals 12 and 22 are connected as described above, DC power is input from the battery body 21 to the inverter 101 via the input / output terminal 22, the input terminal 12, and the power line 102.
The inverter 101 converts the input DC power from the battery 20 into AC power and adjusts the voltage value as appropriate.
Here, when the switch 16 is turned on, the converted AC power can be output from the output terminal 13 via the power line 103. When the switch 16 is turned on and power can be supplied from the output terminal 13, the lamp 17a is lit, indicating that the power can be supplied.
Here, for example, when a plug of an electric device is connected to the output terminal 13 configured as a general-purpose outlet, power is supplied to the electric device.
However, when the amount of power necessary for the operation of the electrical device exceeds the amount of power that can be supplied by the power supply unit, the lamp 17b is turned on, and the power necessary for the operation of the electrical device cannot be supplied. It shows that.
