Problems solved by technology
[0002] With the development of science and technology, mobile terminals such as mobile phones have become an indispensable communication tool in people's daily life. With the increasingly diversified functions of mobile terminals, the problem of charging mobile terminals has become increasingly prominent. The way of charging the power supply, this charging method must be completed in a place with a power supply, and when people are outdoors or on a long journey, sometimes the power supply cannot be guaranteed, so that the mobile terminal is turned off at a critical moment, which brings great harm to the user. inconvenient
[0003] The current mobile terminal solar power supply device can realize self-power supply without an external power supply, but it must work in a place with a light source. Due to external conditions, it cannot realize self-power supply

Embodiment Construction
[0033] The thermal power supply device and the mobile terminal of the present invention use the thermal power supply technology to convert the internal and external heat of the mobile terminal into electric energy for powering the mobile terminal, so that the mobile terminal can self-power at any time.
[0034] figure 1 A schematic of the thermoelectric technology is shown.
[0035] When the two ends of metal A and B of two different materials are connected into a loop, the two nodes of metal A and B are TH and TC, which are hot nodes and cold nodes respectively. When there is a temperature difference between TH and TC, such as TH When the temperature is higher than the temperature of TC, an electromotive force VOUT will be generated in the circuit, which is a thermoelectric effect. The thermoelectric effect can be used to convert thermal energy into electrical energy for power generation. According to the thermoelectric effect, as long as there is a temperature difference of...

The present invention discloses a thermal power supply device and a mobile terminal. The thermal power supply device is used for a mobile terminal, comprising: a thermoelectric conversion module for absorbing heat energy and converting it into electrical energy for output; a charge pump module connected with the thermoelectric The output end of the conversion module is connected to store the electric energy output by the thermoelectric conversion module to output the power supply voltage required by the mobile terminal; the filter and voltage stabilization module is connected to the output end of the charge pump module and used to connect the charge pump module The output voltage is filtered and stabilized to output a DC stable voltage. The thermal power supply device and mobile terminal proposed by the present invention use thermoelectric conversion technology to convert internal and external heat of the mobile terminal into a power supply for the mobile terminal, so that the mobile terminal can self-powered anytime and anywhere without relying on an external power supply.
