BACKGROUND OF THE
Background of the Invention [0002] Today, as the size of a portable terminal is reduced and slimmer, the capacity of a battery built in the portable terminal itself is limited. For example, a smart phone, which is a kind of the portable terminal, has various additional functions such as search, finance, and moving picture playback in addition to the basic call function, and its usage time is gradually increasing.
Due to this, the battery of the portable terminal itself frequently fails to exceed one day due to the capacity limit. Accordingly, it is necessary to replace the battery at least once a day or to continuously charge the battery through a charging cable.
However, when the charging of the portable terminal through the charging cable is difficult, for example, there is a problem that the battery of the portable terminal is exhausted during the long trip or traveling while traveling, thereby turning off the power of the portable terminal.
In particular, since smartphones of recent years are manufactured as a battery-integrated type (built-in type) in which a battery can not be replaced, it is common to purchase and carry a charging auxiliary battery capable of being charged in an emergency.
However, charging through the charging cable may not be possible depending on the surrounding environment, and the conventional charging auxiliary battery has a problem in that it is inconvenient to carry. This is also the case in portable electronic devices such as tablets and PMPs.
Therefore, there is a desperate need to easily charge the main battery of the portable electronic device regardless of the place.
SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a portable electronic device, The flexible battery can be built in, which can increase the usability of the portable electronic device by extending the use time of the portable electronic device by charging the main battery of the portable electronic device anytime and anywhere without having to carry a separate charging auxiliary battery as in the prior art The object of the present invention is to provide a bag which can be charged wirelessly.
It is another object of the present invention to provide a wirelessly chargeable bag which can charge a main battery of a portable electronic device while preserving a circular shape of a bag by providing a separate storage member capable of storing the portable electronic device.
Further, according to the present invention, since a pattern for shrinkage and relaxation is provided in a flexible battery, even if the storage member is made of a soft material, it is possible to flexibly cope with deformation, thereby preventing a breakdown of the flexible battery. There is another purpose to provide.
It is a further object of the present invention to provide a wirelessly chargeable bag capable of realizing thinning by using one wireless power transmission antenna as a wireless power transmission mode or a wireless power receiving mode according to the purpose of use.
In order to solve the above-described problems, the present invention provides a bag- A charging accommodation member having a storage space for storing the portable electronic device and disposed in the storage portion and having at least one battery built therein; And a wireless power transmission antenna that is embedded in the charging housing member and transmits wireless power by using power of the battery so as to charge the main battery of the portable electronic device do.
In addition, the main battery of the portable electronic device can be charged using the radio power transmitted through the antenna for wireless power transmission in a state where the portable electronic device is housed in the storage space.
The charging housing member may include a housing body forming the housing space, and the battery may be housed in at least one side of the housing body.
The charging housing member may be integrally formed with or detachable from the bag body.
Further, the charging housing member may be realized in the form of a pouch.
The antenna for wireless power transmission is used as an antenna for wireless power transmission and serves as an antenna for wireless power transmission for charging a main battery of a portable terminal using a power stored in the battery, And may serve as a wireless power receiving antenna for receiving wireless power and charging the battery.
In addition, the wireless power transmission antenna may be configured such that when the inductance is changed through interaction with an antenna for wireless power transmission provided in the external charger and a power signal transmitted from the external charging device is detected, And may serve as an antenna for receiving wireless power for receiving wireless power.
Also, some of the power stored in the battery may be used as a driving power source for driving the antenna for wireless power transmission.
According to another aspect of the present invention, A charging accommodation member having a storage space for storing the portable electronic device and disposed in the storage portion and having at least one battery built therein; A wireless power transmission antenna embedded in the charging accommodation member to perform a function of an antenna for transmitting or receiving wireless power; And a circuit unit for controlling driving of the antenna for wireless power transmission, wherein the antenna for wireless power transmission receives wireless power supplied from the outside through one antenna and charges the power of the battery, The present invention provides a wirelessly chargeable bag for charging the main battery of the portable electronic device by transmitting the stored power in a wireless manner.
The wireless power transmission antenna is operated in a transmission mode for transmitting power stored in the battery in a wireless manner, and receives wireless power transmitted from the wireless power transmission module through the circuit unit when the wireless power transmission module senses The receiving mode can be switched to the receiving mode.
In addition, the wireless power transmission antenna may periodically transmit a power signal for sensing the wireless power receiving module.
The circuit unit may switch the antenna for wireless power transmission to a receiving mode when a power signal transmitted from the wireless power transmitting module is sensed and the inductance of the antenna for wireless power transmission is changed.
The shielding sheet shields a magnetic field generated in a predetermined frequency band and focuses the shielding sheet in a desired direction on one surface of the antenna for wireless power transmission.
