If there is no mains power in the wild, these chargers cannot charge the batteries of these digital products. In this way, for these digital products, there will be a problem of battery life. In order to solve this problem, there are now Many large-capacity supporting lithium batteries have appeared on the market, which has strengthened the battery life to a certain extent, but it cannot fundamentally solve the problem. Now there are a lot of solar chargers on the market, each solar charger includes a solar panel, a storage battery and a charging circuit. When in the wild, as long as there is sunlight shining on the solar panel, the battery can be charged, and at the same time Charging digital products greatly enhances the battery life of digital products such as mobile phones. However, the area of this solar charger is too large, and it is easy to break the silicon chip under unexpected circumstances, and it is inconvenient to carry.

Contents of the invention

In order to overcome the fact that the solar panels in the prior art are too large and easily cause the solar panels to be broken, the utility model provides a push-pull unfolded or superimposed solar mobile power supply. The panels charge the battery at the same time, and they can also be pulled back and stacked together, which is convenient to carry and use, and after stacking, the battery can also be charged through the solar sub-panel above.

The technical solution adopted by the utility model to achieve its technical purpose is: a solar mobile power supply, including a host and a solar panel, the host includes a control circuit and a battery, and the solar panel is controlled by the control circuit. The storage battery is charged, the storage battery is charged externally through the control circuit, the solar panel includes a first solar sub-panel and a second solar sub-panel, and the second solar sub-panel is arranged on a On the machine base of the above-mentioned host, the first solar sub-panel forms a push-pull or superimposed connection structure on the second solar sub-panel.

Specifically, in the above solar mobile power supply, the first solar sub-panel and the second solar sub-panel are connected in parallel and then connected to the control circuit. The first solar sub-panel is connected in parallel with the second solar sub-panel through the contact of the metal shrapnel during the push-pull process.

Further, in the above solar mobile power supply: the storage battery is a lithium battery with a DC output voltage of 5V. The circuit board is provided with a USB interface circuit.

In the technical solution of the utility model, the solar panels can be pushed and pulled to unfold or stack, and after unfolding, two solar sub-panels can be used to charge the battery at the same time. When carrying them, they can be pulled back and stacked together to reduce the volume. After stacking, the battery can also be charged through the upper solar panel.

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in more detail. .
