Inside the cavity, there is a roller with a spring, and one end of the roller is connected to the lower cover. The other end is connected with the positioning pin, and the solar cell group is wound on the roll, and the solar cell group passes through the slot and is connected with the pull rod to have a structure that can be pulled out and retracted from the slot. The solar battery pack is connected to the power supply by means of wires to form a power supply control circuit.

The preferred solution is that the solar cell group according to the utility model is made of several small-area copper-indium-gallium-selenium solar thin-film cells connected in series and evenly distributed on the soft tarpaulin.

Preferably, the power supply according to the utility model is configured such that the rechargeable battery, the anti-reverse charging diode and the controller are electrically connected in turn and placed inside the upper cover, and function keys and charging and discharging interfaces are provided outside the upper cover.

Preferably, the controller according to the present invention includes a switching circuit, a charge and discharge control circuit and an output control circuit.

A preferred solution is that the function keys according to the present invention include an on-off key, a voltage-regulating key and a voltage indicator light.

The beneficial effect of the utility model is that the soft solar cell group is adopted so that it can be arbitrarily curled, shrunk and expanded. In power-scarce areas without mains supply, in the wild or not close to the power grid, it can not only achieve the effect of using solar energy for charging and power supply, but also form a power supply source anywhere to meet the charging needs of various portable appliances. , greatly improving the immediacy and convenience of people using power outdoors. Not only that, but also has the advantages of simple structure, high reliability and long service life.
