Abstract

An electronic device comprises a thermoelectric device, which comprises a first contact surface and a second contact surface, is capable of converting the thermal energy generated by the temperature difference between the first contact surface and the second contact surface into electric energy, and generates a thermoelectric power supply; a control module, which is couple to the thermoelectric device and is used to convert the thermoelectric power supply and output to a first power supply according to a control signal; a battery module, which is coupled to the control module, is charged by the first power supply and outputs the power to a second power supply; and an operation module, which is coupled to the control module and the battery module, is operated by utilizing the first power supply and the second power supply, and is capable of generating the control signal according to a preset value.

Description

technical field [0001] The present invention relates to an electronic device, in particular to an electronic device that uses an internal thermoelectric device to convert heat energy generated during operation into electrical energy for self-charging. Background technique [0002] Generally speaking, a battery module is required inside the portable electronic device to provide the power required for the operation of the electronic device without an external power supply. However, as electronic devices such as tablet computers or smart phones are more and more widely used, the calculation amount of application programs in electronic devices, the amount of data transmitted through the network, or the resolution of screens, etc. have all increased correspondingly, which in turn makes electronic devices The power consumption of the device has also increased significantly. [0003] In this situation, in order not to shorten the time for users to operate the electronic device, th...
