A power supply ring 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 6.
As shown in fig. 1 to 6, the power supply finger ring 100 according to the embodiment of the present invention includes a body 10. Particularly, body 10 is arc or loop configuration, and body 10 is equipped with power supply joint 11 and the joint 12 that charges, and power supply joint 11 locates the one side of body 10, and the opposite side of body 10 is located to the joint 12 that charges, and it is corresponding with power supply joint 11 in the both sides position of body 10 to charge joint 12. The power supply connector 11 is used for connecting with a device to be charged so as to charge the device to be charged, and the charging connector 12 is used for connecting with the power supply connector 310 of the ring charging stand 300 so as to be charged by the ring charging stand 300.
In other words, the power supply ring 100 according to the embodiment of the present invention is mainly composed of a body 10 that can be fitted over the user's finger and can be engaged with the smart ring 200 placed on the user's finger. A battery system including a built-in rechargeable battery and a charge and discharge circuit capable of charging and discharging electric energy to and from the built-in rechargeable battery is provided inside the body 10. Be equipped with power supply joint 11 and the joint 12 that charges on body 10 respectively, can realize releasing the electric energy through power supply joint 11, realize charging the electric energy through the joint 12 that charges.
Specifically, when the intelligent ring 200 needs to be charged, on one hand, the ring charging head 210 may be electrically connected to the power supply head 310 of the ring charging stand 300, and the intelligent ring 200 is directly charged by the ring charging stand 300. That is, when the electric energy stored in the built-in rechargeable battery is insufficient, the charging connector 12 of the main body 10 may be connected to the power supply connector 310 of the ring charging stand 300, and the main body 10 may be charged by the ring charging stand 300. In yet another aspect, the power supply connector 11 of the body 10 may be connected to the ring charging head 210 of the smart ring 200, the power supply connector 11 interfacing with the ring charging head 210 to form an electrical connection. Therefore, the power supply ring 100 and the intelligent ring 200 can share one ring charging seat 300, and a special charging seat is not required to be additionally arranged.
Optionally, after the power supply connector 11 is connected to the ring charging head 210, the intelligent system inside the intelligent ring 200 may select to supply power by the built-in rechargeable battery or by the power supply ring 100 according to the power condition of the built-in rechargeable battery, and usually, after the built-in rechargeable battery is lower than a certain power, switch to the power supply ring 100 to supply power, and at the same time, the power supply ring 100 charges the built-in rechargeable battery. That is, powered ring 100 acts as a backup power supply battery for smart ring 200.
In addition, when adopting body 10 to charge to intelligent ring 200, intelligent ring 200 need not to take off from the finger, and body 10 and intelligent ring 200 can overlap simultaneously and establish in the finger periphery, can form stable electrical connection between body 10 and the intelligent ring 200, and can not influence the activity of finger, and user's hand is controlled flexibility ratio and comfort level and can not receive the influence.
Further, as shown in fig. 3, the charging connector 12 corresponds to the power supply connector 11 at both side positions of the body 10. That is to say, the charging connector 12 and the power supply connector 11 are arranged relatively along the thickness direction of the body 10, and when the user wears the power supply ring 100 and the intelligent ring 200 with his finger, the ring charging connector 210 can be electrically connected with the power supply connector 11 quickly without being hindered by the charging connector 12. Moreover, the charging connector 12 and the power supply connector 11 are respectively arranged on two sides of the body 10 and are corresponding to each other, that is, the projection position of the charging connector 12 on the body 10 corresponds to the projection position of the power supply connector 11 on the body 10, so that the processing design of the charging connector 12 and the power supply connector 11 is facilitated, and the internal circuit structure is simplified; moreover, the charging connector 12 and the power supply connector 11 are not easily contacted with the skin and do not press against the skin.
