Problems solved by technology

[0004] However, the current traditional solar charging system can only receive the power of the solar panel to charge the battery on a sunny day or under strong lighting conditions, and cannot start charging on a cloudy day with weak light or indoor lighting.
So this harsh requirement that it can only work on a sunny day with direct sunlight makes the solar charging system have a small scope of application

Abstract

The invention discloses a mobile terminal, which comprises a battery, a solar battery, a direct current charging module, a solar charging module, a switching unit and a control unit, wherein the solar charging module is used for carrying out voltage boosting conversion or voltage reduction conversion on the voltage generated by the solar battery to obtain the charging voltage of the battery, the switching unit is used for switching and selecting the solar charging module or the direct current charging module for charging the battery, and the control unit is used for controlling the on-off state of the solar charging module and the direct current charging module, controlling the switching action of the switching unit and detecting whether the direct current charging module has the direct current power supply input or not. The mobile terminal has the advantage that through the voltage boosting and the voltage reduction on the voltage generated by the solar battery, the solar charging can also be realized in cloudy days or at nightfall or under the indoor illumination conditions. In addition, the uninterruptible charging power supply in the mobile terminal is realized through the combination of the mobile terminal and the direct current charging, so the time for continuously using the mobile terminal is effectively prolonged.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a solar-charged mobile terminal. Background technique [0002] At present, the computing and processing capabilities of handheld electronic devices (smart phones, GPS trackers, tablet computers) have advanced by leaps and bounds, which greatly meets the basic requirements of users for communication and entertainment. The continuous development of handheld electronic devices requires batteries as power supply to provide communication services to users in any place. However, the improvement of CPU processing speed and the improvement of other hardware performance are accompanied by the increase of energy consumption. The power supply battery of handheld electronic devices brings challenges, and the battery cannot work for a long time, and needs to be recharged repeatedly after the power is exhausted to supply the necessary power for electronic devices. In this way, in a place where dir...
