Description

Technical Field

[0001] The invention relates to a charging device, in particular to a solar powered mobile equipment charging device. Background Art

[0002] At present, mobile electronic devices such as mobile phones and tablets are generally charged with fixed power supplies or mobile power supplies (power banks), and they need to be charged or the batteries need to be replaced frequently, which is very inconvenient. When traveling or performing work tasks, if the mobile phone battery or mobile power supply is out of power and there is no fixed charging power supply, the portable electronic devices cannot be used, which brings inconvenience to travel.

[0003] In order to solve the above problems, solar mobile device chargers that can be charged by solar energy have come into being. Solar energy, as a kind of clean energy, is widely used in the field of power generation. For example, the Chinese invention patent with patent number 201210534317.4 discloses a high-efficiency solar mobile phone charging sleeve, including a sleeve body, a solar panel, an integrated circuit and a mobile phone charging port. The solar panel is embedded in the sleeve body to convert solar energy into electrical energy, and the integrated circuit is used to regulate the voltage and stabilize the current to charge the mobile phone on the sleeve body. The high-efficiency solar mobile phone power storage charging sleeve of the present invention has high charging efficiency and can be fully charged in a short time; due to the use of back electrode connection technology, the appearance is beautiful and generous. In addition, by combining a high-efficiency flexible solar cell with a mobile phone sleeve, the shell of the mobile phone can be protected from scratches, and at the same time, the high-efficiency solar panel can provide a continuous power supply to the mobile phone, ensuring long-term standby and use of the mobile phone. However, it sometimes still has the following defects:

[0004] 1. The mobile phone case can only be used in the field of mobile phone charging, and cannot be applied to other mobile devices such as tablet computers. In addition, the solar panel is installed on the back of the mobile phone case. When charging, the back of the mobile phone case, that is, the solar panel side, needs to face up, and the mobile phone screen faces down. On the one hand, the mobile phone cannot be used while charging, and on the other hand, the screen of the mobile phone facing down is easy to be scratched, causing economic losses;

[0005] 2. Since the output power of solar panels is affected by temperature, that is, for every 1°C increase in the temperature of the solar cell, the output power of the N-type single crystal module decreases by 0.38% of the baseline value, and the output power of the P-type module decreases by 0.42% of the baseline value. Therefore, when the mobile phone case is in use, the solar panel is very close to the mobile phone battery. The large amount of heat generated by the mobile phone battery during charging will be transferred to the solar panel. As the charging time increases, its charging efficiency will drop significantly.
