Description

TECHNICAL FIELD [0001] The present invention relates to a band for a wrist wearing type electronic apparatus and an electronic apparatus including the band.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a band for a wrist wearing type electronic device and an electronic apparatus including the same.

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 order to overcome such a problem, a technology has been developed in which a flexible battery is incorporated in a band of a wristwatch-shaped smart device to supply power to the battery of the main body. When the flexible battery built in the band is overheated, The main body may be damaged due to overheating of the main body.

Here, the pattern 28 formed on the electrode assembly 20 is formed parallel to a straight line parallel to the width direction as shown in Fig. It will be appreciated that the pattern 36 formed on the casing 30 and the pattern 28 formed on the electrode assembly 20 need only be matched with each other.

13 to 16, the crests and valleys may be continuous or discontinuous, and the cross-sectional shapes of the crests and valleys may be a linear pattern, a prism pattern, a semicircular pattern, a wave pattern A pattern, a polygonal pattern, and a mixed pattern thereof.

Meanwhile, the flexible battery 10 described above functions to supply power to the band body 110 (see FIG. 1), and functions as an auxiliary battery for assisting the main battery provided in the band body 110 Or may be used as the main battery of the band body 110. [

When the flexible battery built in the band 100 for a wrist wearable electronic device of the present invention is overheated, the flexible battery can be quickly removed from the band.

In addition, the band for a wrist wearable electronic device and the electronic device including the band for a wrist wearable electronic device of the present invention can be configured such that even when a flexible battery mounted inside a band for a wrist wearable electronic device is overheated, the main body is not damaged by the flexible battery .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
