A smart phone case for solar energy and thermoelectric power generation

Abstract

The invention relates to a solar energy and temperature difference power generation intelligent mobile phone shell. The solar energy and temperature difference power generation intelligent mobile phone shell comprises a flip type shell, a solar panel, a solar charging circuit, a solar film, a storage battery, a discharging circuit, an external power supply charging circuit and temperature difference power generation sheets which are fixed in the flip type shell, and a temperature difference charging circuit which is electrically connected with the temperature difference power generation sheets, wherein the solar film is connected in parallel with the solar panel; the charging end of the storage battery is connected the solar charging circuit, the temperature difference charging circuit and the external power supply charging circuit respectively through leads; the discharging end of the storage battery is connected with the discharging circuit through a lead; a microprogrammed control unit (MCU), switch modules and an electric quantity detection module are arranged on the flip type shell; the MCU is connected with the storage battery through the electric quantity detection module; and the MCU is electrically connected with the solar charging circuit and the temperature difference charging circuit through the switch modules. Through adoption of the mobile phone shell, solar energy generation and temperature difference power generation are integrated; the storage and display of electric quantity can be realized; and the energy utilization ratio is high.

Description

technical field [0001] The invention relates to a mobile phone case, in particular to a smart mobile phone case capable of generating electricity, and belongs to the field of mobile phone accessories. Background technique [0002] At present, smart phones are widely used as necessary communication and entertainment devices in people's daily work and life. Due to the large screen, WIFI, GPS, Bluetooth and other multi-functional hardware configurations of smart phones, their power consumption is high and their standby time is short. , The built-in battery capacity of the smart phone cannot meet the long-term power supply, and the built-in battery needs to be charged frequently. Therefore, people need a kind of portable mobile charging device under the environment that does not have mains power such as outdoor travel, and then mobile charging treasure has been subjected to people's favor. However, the mobile power bank needs to be connected to the mains to charge before use, a...

However, since this type of mobile phone case does not have an energy storage element, it cannot store charges, so that the mobile phone battery cannot store the light energy incident on the surface of the mobile phone case when it does not need to be charged or is fully charged, resulting in a waste of energy.

In addition, solar energy is affected by sunlight, and this kind of solar smartphone case cannot receive enough solar energy to charge the battery of the mobile phone under the condition of insufficient sunlight

In addition, the mobile phone case does not have the storage power display function and charging management function, nor does it have an external interface for charging other external devices.

[0004] The Chinese invention patent "solar 4G environmental protection mobile phone" (application number: CN201110391578) discloses a mobile phone with a solar charging / control function in the shell. Electric charging and mobile power charging), this kind of solar mobile phone case needs to change the structure of the mobile phone itself, and does not have the function of external interface for charging other mobile phones and other peripheral devices, so the practicability and versatility are not strong

[0005] Since the photoelectric conversion efficiency is only about 20%, the existing mobile phone cases that use solar energy to generate electricity, except for a small part of the solar energy absorbed by the solar power generation components, are reflected, and the rest is converted into heat energy, and the smartphone generates a lot of heat during use. , how to improve the use efficiency of solar energy and effectively use the heat generated by the mobile phone itself has become an urgent problem to be solved for the power generation mobile phone case
