Wearable power supply and hand worn mobile device having the same

Abstract

A wearable power supply includes a strap to be worn on a user's wrist, arm, waist, leg or head; a flexible secondary battery carried by the strap; and a connector slot disposed on the strap and electrically connected to the flexible secondary battery, wherein the flexible secondary battery is capable of supplying current to a mobile device via a connecting wire connected between the connector slot and the mobile device, and is recharged from an external power supply connected to the connector slot. When the wearable power supply takes the form of a wristband, it can be used as a carrier of a hand worn mobile device, such as a smart watch or a smart bracelet, to provide a longer operating range.

What is claimed is: 
     
         1 . A hand worn mobile device, comprising:
 a strap worn on a user;   a plurality of module slots formed on the strap; and   a plurality of mobile device peripheral modules inserted in the module slots respectively.   
     
     
         2 . The hand worn mobile device as claimed in  claim 1 , wherein the module slots include but are not limited to battery module slots, connector slots, memory card module slots, SIM card module slots, keypad module slots, earphone module slots, speaker module slots, camera module slots and light source module slots. 
     
     
         3 . The hand worn mobile device as claimed in  claim 1  further comprising a mobile device body which is attached to the strap and provided with a built-in microcontroller which is electrically connected to the module slots. 
     
     
         4 . The hand worn mobile device as claimed in  claim 3 , wherein the mobile device body includes a display screen or a set of indicator lights electrically connected to the microcontroller. 
     
     
         5 . The hand worn mobile device as claimed in  claim 3 , wherein the mobile device body includes a heart rate sensor which is electrically connected to the microcontroller to detect the user's heart rate.
