    The suitcase type solar power generation / power supply device of the present invention can be easily moved by human power by installing independent solar power generation and power supply in a suitcase for travel provided with a caster with stopper and a handle whose length can be adjusted. It can be carried, can be used for outdoor activities, can respond to urgent power demands during disasters, etc., considers the natural environment, and can be stored and transported as a suitcase when not in use. It was.

    At least two solar cell panel parts that can be folded, and when used, the solar cell panel part is opened and the solar cell panel part is mounted on the rail attached to the main body in order to adjust the angle in the direction of the sun. By adjusting the slide attached to the surface, the angle between the light receiving surface of the solar cell panel and the ground is adjusted steplessly from the vertical direction to the ground direction, and the same angle is fixed and maintained by the stopper. In addition, it has become possible to respond to urgent power demands such as during disasters, starting with the use of electricity outdoors.

    By attaching a detachable external AC plug cord, external AC power can be input via an AC / DC converter.

    By attaching a detachable external DC plug cord, external DC power can be input.

    In order to make the total area of the light receiving surface of the solar cell panel as large as possible, the solar cell panel is arranged with multiple solar panels that can be folded in multiple layers. The power storage unit installed on the main body is slidable or detachable from the main body, and uses a battery with a small and light battery capacity as much as possible. The generated power of the solar cell changes depending on the sunshine conditions, and the power consumption increases depending on the application. Therefore, there is a caster with a stopper and a length-adjustable handle that provides constant and efficient output power by controlling the input / output of the storage battery with the control unit, improving portability and portability by human power. A suitcase-type solar power generation / power supply device.

    The solar cell unit 1a is formed by attaching a hinge 1d between two solar cell panels 1a1 of 72W and 12V, and the light receiving surfaces of the solar cell units 1a are opposed to each other, and separated between another set of solar cell panels 1a1. The hinge 1d is attached to form a four-fold solar cell portion 1a.

    Sliders 1b are attached to the upper two corners of one solar cell panel 1a1, respectively, and one metal clamp receiver is formed at the lower end.

    A front cover 2a1 is attached to the front of the main body, rails 8 are incorporated on the outer sides of both sides, a caster 13 with stoppers on the left and right at the bottom of the back, a handle 9 with adjustable length at the top of the back and a fastener 12 on the bottom. The shape of a suitcase for use.

    The main body includes a controller 3a, a display / operation panel 3b, a DC input / output terminal 3c for 12V, an AC input terminal 4a for 100V, an AC / DC converter 4B for converting AC 100V to DC 12V, and a 12V / 5Ah lithium ion battery pack. 20 inverters 6a, an inverter 5a for converting DC 12V to AC 100V, and an AC outlet 5b are installed.

    The controller 3a inside the main body outputs the input from the solar cell unit 1a to the inverter 5a that converts DC 12V to AC 100V. The output converted to alternating current is distributed to the AC outlet 5b.

    When a direct current of 12V DC is input from the solar cell unit 1a to the controller 3a inside the main body and the output to the inverter 5a for converting the direct current 12V to the 100V AC is stopped, the direct current 12V is output to the power storage unit 6 under the control of the controller 3a. .

    The controller 3a inside the main body receives an input from the solar cell unit 1a, and distributes it to the AC outlet 5b via an inverter 5a that converts DC 12V to AC 100V.

    When the output to the inverter 5a becomes larger than the input from the solar cell unit 1a to the controller 3a, the power is input from the power storage unit 6 to the controller 3a by the control of the controller 3a, and the power of the solar cell unit 1a and the power storage unit 6 is added by the control. Output.

    When the weather condition is bad or the remaining capacity of the power storage unit 6 is insufficient, the detachable external DC cord 11 is inserted into the 12V DC input / output terminal 3c to input from the external DC power source.

    The input unit is connected to the external AC power source by inserting the detachable external AC plug cord 10 into the 100V AC input terminal 4a, and the AC from the AC input terminal 4a is connected to the AC / DC converter 4b. It is converted to DC 12V and input to the controller 3a.

    The method of simultaneously using a plurality of the present invention is to connect the second generation detachable external AC plug cord 10 to the first generation AC outlet 5b to the second generation AC outlet 5b. The sum electric power of the solar cell unit 1a and the power storage unit 6 is obtained.

The power storage unit 6 is formed of at least one battery and performs input / output with the controller 3a.

    It can be used not only for outdoor entertainment activities such as camping and picnics, but also for emergency power generation equipment at the time of disasters and facilities where power consumption fluctuates greatly depending on the situation of users, etc., and can be used as temporary power.
