Problems solved by technology

[0005] A type of small mobile electronic device similar to a mobile phone, but also has the above problems, especially when the power supply cannot be found in time during long-distance travel
These devices are convenient to use because they can be small and small and can move freely, but at the same time, due to their small size, their battery capacity is limited, and when they cannot be charged in time, the use time is relatively short. This defect can be excellently solved by the present invention

Embodiment 1

[0034] This embodiment takes a bar mobile phone as an example, and discloses a solar battery charging device combined with a mobile phone. At the back end of the mobile phone battery of the candy bar mobile phone, there is a chamber for accommodating flexible thin-film solar cell rolls. The piece goes in and out, and grooves are designed at both ends of the gap. A double-sided CIGS thin-film solar cell roll is installed in the chamber, and the center of the battery roll is equipped with a metal conductive aluminum film on both ends to realize the conduction function with the lead-out electrodes of the CIGS battery, and a wrench position structure is provided at one end to facilitate the position limit The shaft sleeve clamps the position-limited rotating shaft, and a position-limiting shaft sleeve capable of moving in the axial direction is provided at the corresponding end, and a torsion spring is additionally designed at both ends of the rotating shaft. The lead-out electro...

Embodiment 2

[0038]This embodiment takes MP4 as an example, and discloses a solar battery charging device combined with the casing of MP4. At the back end of the battery, there is a chamber for accommodating flexible thin-film solar battery rolls. The chamber is composed of a front shell and a back shell. At the junction of the two shells, a narrow and long gap is designed to allow solar cells to enter and exit. At both ends of the gap, grooves are designed. A double-sided CIGS thin-film solar cell roll is set in the chamber, and the center of the battery roll is provided with a hollow hole, and a through hole that is compatible with the hollow hole is provided at the near end, from which flexible metal electrode wires can be drawn out to make the electrode wires separate One end is connected to the positive and negative electrodes of the CIGS battery, and the other end is connected to the lead-out electrode of the shell leading to the battery holder, so as to realize the function of power...

Abstract

The invention discloses a solar battery charging device combined with a mobile phone. The solar battery charging device comprises a mobile phone casing, a rotating shaft, a torque spring, a solar cell, an extraction electrode and a bypass diode, wherein a chamber for accommodating the solar cell is arranged at one end of the mobile phone casing; the rotating shaft is installed in the chamber, and the torque spring is arranged on the rotating shaft; the solar cell is a flexible thin-film solar cell and is wound on the rotating shaft; and the extraction electrode and the bypass diode are arranged on the mobile phone casing to form a passage with a mobile phone electrode seat. When the mobile phone needs to be charged, the thin-film solar cell is drawn out of the chamber and unfolded to be exposed under light rays, and accordingly charging of the mobile phone is achieved. When the charging is finished, by means of restoring forces of the torque spring, the thin-film solar cell is rewound on the rotating shaft. The mobile phone involved in the invention represents small size mobile electronic devices with the mobile phone as the main device, and the small size mobile electronic devices comprise MP3, MP4, notebook computers, electronic books and the like.

Description

technical field [0001] The invention relates to the field of solar mobile phone batteries, and is especially suitable for a structure and a device for charging mobile phone batteries by using thin-film solar cells. Background technique [0002] The use of solar cells as mobile phone chargers is one of the many applications of solar cells in daily life. It can be easily carried without worrying about being away from the grid, unable to find a suitable socket, etc., and does not need to replace the battery frequently, which is very convenient. [0003] However, it is necessary to carry a charger outside the mobile phone for charging. Sometimes it is easy to forget to carry the charger and cause trouble. In addition, sometimes the charger has a large volume and is inconvenient to carry. [0004] In order to solve the above problems, the present invention utilizes the advantages of flexible thin-film solar cells that can be wound, small volume, and strong weak light, and designs...
