The specific design of the winding mechanism 124 is generally known in the technical field of the present invention, and is mainly composed of components such as a scroll spring, a winding machine, and gears. The detailed description of is omitted.

  The connecting line 14 includes one first section 142 and one second section 144 that are interconnected.

The second section 144 is wound around the winding mechanism 124. One end of the second section 144 extends out of the outer shell 10 from the opening 104 ′ by pulling from the outside.

  The first connector 16 and the second connector 18 are electrically connected to one end of the first section 142 and one end of the second section 144 of the connection line 14, respectively. In the present embodiment, the first connector 16 is installed in the outer shell 10 and extends from the opening 104. The first connector 16 and the second connector 18 are different types of connectors. In this embodiment, the first connector 16 is a USB Type A connector, and the second connector 18 is a lighting connector. Other types such as B and Type-C may be used. In actual application, the first connector 16 and the second connector 18 may be the same type of connector.

  The wireless power transmission module 20 includes one induction coil 22 and one conversion circuit 24. The induction coil 22 receives electromagnetic energy from the outside, converts it into one electric signal, and outputs it to the conversion circuit 24. Used. The conversion circuit 24 converts the electric signal into electric power and outputs it. In actual application, methods for receiving electromagnetic energy include magnetic induction or electromagnetic coupling. In this embodiment, the induction coil 22 and the conversion circuit are installed on one first substrate 26 and one second substrate 28, respectively. When the first substrate 26 is installed in the container 106, the induction coil 22 is positioned in the container 106. The second substrate 28 is installed in the outer shell 10, and the first connector 16 is directly connected to the second substrate 28. The induction coil 22 is connected to two conductive parts such as a conductive wire 222, and the two conductive wires 222 are electrically connected to the conversion circuit 24 located on the second substrate 28 through the perforations 108 of the outer shell 10. At least one of the conductive wires 222 is electrically connected to the conversion circuit 24 through one protection module 29. The protection module 29 is used to prevent damage to the conversion circuit 24 by blocking the output of the electric signal to the conversion circuit 24 when an abnormality occurs in the electric signal output by the induction coil 22. In actual application, a fuse, a temperature impedance element (a positive temperature coefficient thermistor, etc.) is adopted, or an electric signal output from the induction coil 22 is detected by an integrated circuit. Either a mechanism for blocking the output of an electric signal is used, or a transistor, a detection circuit and an MCU are used together, an electric signal is detected by the detection circuit, and if there is an abnormality, the program code is executed by the MCU and the conversion circuit 24 is controlled by controlling the transistor.

The first connector 16 and the opening 104 can be electrically connected to each other with a certain distance so that the first connector 16 can be easily inserted into the slot of the battery device that is relatively packed. The conductive component is not limited to the conductive wire 222, and may be a conductive needle and needle seat coupled or electrically connected by a board point-to-point method.

  As an electrical connection method between the first connector 16 and the first section 142 of the connection line 14 and the conversion circuit 24, the first connector 16 and the connection are made by connecting with a conductive wire or by providing a conductive circuit on the second substrate 28. The three of the line 14 and the conversion circuit 24 can be electrically connected to each other. What is important is that the connection portion between the conversion circuit 24 and the connection line 14 first section 142 is located outside the winding mechanism 124, so that the connection portion does not have to worry about being caught in the winding mechanism 124 by an external force. Therefore, it is possible to prevent the conversion circuit 24 and the connection line 14 from falling off. In actual application, both the induction coil 22 and the conversion circuit 24 are installed on the first substrate 26, and the conversion circuit 24 is separately connected to a conductive wire or other electrical connection method (for example, a conductive circuit on the first substrate 26 or It is also possible to make an electrical connection with the first section 142 of the connection line 14 through the printed circuit board.
