Embodiment 1

[0036] Please refer to figure 1 Embodiment 1 of the present invention provides a mobile terminal 100. The mobile terminal 100 includes a thermoelectric battery 110. The thermoelectric battery 110 generates electricity using a temperature difference. The obtained electric energy is used by the mobile terminal 100. figure 1 Arrow 11 represents heat input, while arrow 12 represents heat dissipation, which means that, in figure 1 The upper surface temperature of the thermoelectric battery 110 close to the arrow 11 is higher, while the lower surface temperature of the thermoelectric battery 110 close to the arrow 12 is lower, so there is a temperature difference between the upper and lower surfaces of the thermoelectric battery 110, and this temperature difference ensures that the thermoelectric battery 110 has an external environment for power generation. condition. In this example, figure 1 The heat input represented by the middle arrow 11 preferably comes from the heat release...

Embodiment 2

[0039] Please refer to figure 2 , this embodiment provides a smart phone 200 (a mobile terminal).

[0040] In this embodiment, the thermoelectric battery 210 is designed to be the same flat block as most common batteries. And same as existing smart phone battery, this temperature difference battery is installed in the groove (unlabeled) designed on the back of smart phone 200, as figure 2 shown. However, in other embodiments, the thermoelectric battery 210 may also be electrically connected to the mobile phone in other ways (for example, electrically connected through a charging connection line). The flat block is made of thermoelectric conversion material and has a heat receiving surface 211 and a heat dissipation surface 212 . In order to make the heating surface close to the human body conveniently, in this embodiment, the heating surface is arranged on the outward facing side of the smart phone 200 .

[0041] Thermoelectric conversion materials generally include meta...

Embodiment 3

[0044] Please refer to Figure 4 , Figure 4 It is a block diagram of each component of this embodiment. In this embodiment, the mobile phone 400 is taken as an example, and the mobile phone 400 includes a thermoelectric power generation element 410 and a battery 420 . In this embodiment, preferably, the mobile phone 400 is a smart phone. In this embodiment, one side of the thermoelectric power generation element 410 is close to the human body. Because human beings are constant temperature animals, there is always a temperature difference between the ambient temperature 42 and the human body temperature 41. This temperature difference can make the thermoelectric power generation element 410 generate electricity. The principle of power generation can refer to Embodiment 1 and Embodiment 2.

Abstract

The invention provides a mobile terminal, a temperature difference power generating device and electronic products with the temperature difference power generating device. The mobile device comprises a temperature difference battery, the temperature difference battery uses temperature difference to generate electricity, and the electricity is provided for the mobile device to use. The mobile device uses the temperature difference battery to replace an existing battery to supply power to the mobile device. Due to the fact that the temperature battery can use the temperature difference to produce electrical energy at any time, battery cruising ability of the mobile terminal can be improved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a mobile terminal, a thermoelectric power generation device and an electronic product with a thermoelectric power generation device. Background technique [0002] With the advancement of science and technology, the impact of the battery device of the electronic product on the entire electronic product is increasing. Taking smart phones as an example, all aspects of configurations (such as super large screens, dual-core or even quad-core CPUs, cameras with more than 10 million pixels, etc.) have been greatly improved. Although these high configurations bring users a better experience, But it also puts forward higher requirements on the battery life of mobile phones. While pursuing high configuration, body thinning has become a fashion pursuit for smartphones. The industry has developed a variety of ultra-thin smart phones, and the thinnest smart phone is only about 7mm thick. Althoug...
