Description

A bracelet-type auxiliary battery capable of storing data,

The present invention relates to a bracelet type auxiliary battery capable of storing data.

In general, a smartphone terminal is a multimedia integrated device, which is indispensable to modern people. Unlike a conventional mobile phone terminal, a smart phone terminal is intended to perform various functions such as internet, application, TV, navigation, and SNS.

In order to implement various functions of a smartphone terminal, the size of the smartphone terminal becomes large due to a large display, so that it is inconvenient to carry the mobile phone when it is worn with a simple attire such as a walk or a sport, and theft and loss are caused.

Further, when the smartphone terminal is carried in a bag or the like, there is an inconvenience that the smartphone terminal is taken out and used for receiving, making an outgoing call or using a message function, and the user is unable to listen to the vibration or ringing of the smartphone terminal There is a problem in that an incoming call and a message are not received.

In order to solve such a problem, a band-type portable terminal has been proposed.

The 'band-type mobile terminal' is suggested to be worn like clothes or jewelry, and a wristwatch-type smart device worn on the wrist or arm is being released. A wristwatch-shaped smart device (aka "smart watch") is small in size and lightweight, allowing you to check your incoming calls and messages while you are always on your wrist.

However, since the conventional smart watch has a power supply for operating the device only in the main body, the supply time of the power supply is limited, shortening the use time, and charging the device when the power is consumed during the outdoor activity is very troublesome .

In addition, in the case of the conventional smart watch, there is a problem that a space for storing the data is insufficient when the data usage is increased.

Accordingly, the flexible battery unit 120 according to an embodiment of the present invention facilitates shrinkage and relaxation in the longitudinal direction through the pattern 36 when bending.

Therefore, even if the repeatedly bending operation of the case 30 is repeated, the fatigue applied to the case 30 itself can be reduced, and the electrode assembly 20 disposed inside the case 30 can also be bent Thereby being protected from the load generated during the operation.

In addition, the pattern formed on the casing member 30 may be formed on the entire surface of the casing member 30 or may be partially formed.
