Description

Portable solar power unit

The present invention relates to a portable photovoltaic power generation device, and more particularly, to a portable foldable photovoltaic power generating device that is easy to move and store because the photovoltaic power unit can rotate in vertical, left and right directions.

Nowadays, with the development of mobile communication technology, mobile terminals (electronic devices), which have become a necessity of modern people, provide various optional functions such as a mobile broadcast reception function, a video playback function, and a camera function.

As the above-described various functions are provided, the amount of time a user uses the mobile terminal for other purposes (eg, listening to music, playing games, etc.) in addition to the purpose of calling is increasing. Accordingly, although an increase in the capacity of the battery is required, the increase in the capacity of the battery is limited due to the characteristics (size constraint) of the portable terminal.

Accordingly, when the battery power is exhausted after using the mobile terminal for a certain period of time, it must be charged by receiving power from the outside. However, when it is difficult to receive power, it is difficult to use the mobile terminal, which is very inconvenient.

Furthermore, since it is more difficult to receive power from the outside when going on a camping trip, there is a problem in that it is very inconvenient to use electronic devices such as electric lamps and portable terminals that need to be charged and used by receiving power from the outside.

In order to solve the above problems, Korean Patent Registration No. 10-1410492 can store a plurality of solar panels by overlapping them, thereby reducing the area occupied by the solar panels. It has the advantage of preventing the damage of the photovoltaic device, and it is folded toward the main body to reduce the area occupied by the solar panel and the size and volume of the photovoltaic device. However, there is a problem in that the solar panel is not detachable and can only be folded, so the solar heat collecting efficiency is somewhat lowered, and it has to be carried and moved while a plurality of solar panels are attached.

In addition, Korea Patent No. 10-1394207 discloses that the solar heat collecting module is a foldable solar heat collecting module that can be opened and closed by folding in the shape of an umbrella, making it easier to carry and having a body structure that can be carried on the shoulder of the human body. Although a technology related to a charging device using a portable and foldable solar cell that can be carried and used at all times and is capable of carrying out the use of a portable charging device with a reinforced support for fixing and supporting the portable charging device has improved light collecting power, the solar heat collecting module It is formed in a triangular shape, so it is less easy to manufacture than a square, and when folded in an umbrella shape, the length of the solar heat collecting module does not decrease, so there are problems in that it is inconvenient to move and there is a risk of damage to the solar panel.
