Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

The present invention includes a power supply apparatus 5 and a power receiving apparatus 6 capable of matching charging. The power receiving device 6 is, for example, a mobile phone, an electronic watch, a tablet computer, etc., and the power supply device 5 is, for example, a power bank, etc., and the present embodiment is described by taking the power supply device 5 as the power bank and the power receiving device 6 as the mobile phone.

The invention is to refit the existing charger, the existing charger will include outer casing, electric core and circuit board, there are charging circuit and discharge circuit on the circuit board, the power supply unit 5 has charging interfaces, also there are charging interfaces, in order to be suitable for different apparatuses, some will set up a plurality of different charging interfaces, some chargers also have mains switches, in order to can illuminate or other uses, also have USB interfaces, these are the known technology of the technicians in this field, do not make the special restriction to this invention. The invention improves the prior charger baby in that: a magnet 1, a metal ring A2 and a metal ring B3 are sequentially arranged on the surface of a housing of the charger from inside to outside, and the magnet 1, the metal ring A2 and the metal ring B3 are all adhered to the housing of the charger. The places corresponding to the metal ring A2 and the metal ring B3 on the casing of the charger are respectively provided with a lead leading-out hole 4, then the metal ring A2 and the metal ring B3 are respectively connected with the positive pole and the negative pole at the discharge circuit output port on the circuit board of the power supply device 5 through the lead leading-out hole 4, the leads led out from the positive pole and the negative pole at the discharge circuit output port are respectively welded on the metal ring A2 and the metal ring B3, and thus the metal ring A2 and the metal ring B3 are respectively used as the positive pole and the negative pole of the charger.

When the charger is used for improvement, the problem of insulation between the metal rings A2 and B3 and the charger housing needs to be considered, when some charger housings are soft rubber, the problem of insulation between the metal rings A2 and B3 serving as the positive electrode and the negative electrode needs to be considered at this time, but when some charger housings are made of conductive materials such as metal and the like, the problem of insulation between the metal rings A2 and B3 serving as the positive electrode and the negative electrode needs to be considered. When the precious shell that charges is electrically conductive material, at this moment metal loop A2, metal loop B3 all paste on the precious shell that charges through insulating glue.

The invention improves the prior mobile phone in that: similarly, a magnet 1, a ferrule a2, and a ferrule B3 are provided in this order from the inside to the outside of the case of the conventional cellular phone. Similarly, two lead wire leading-out holes 4 are also provided on the housing of the powered device 6, and the metal ring a2 and the metal ring B3 on the powered device 6 are respectively connected with the positive pole and the negative pole at the charging circuit input port on the main board of the powered device 6 through the lead wire leading-out holes 4. The same as the improvement of the charger, the leads led out from the anode and the cathode at the input port of the charging circuit on the mainboard are respectively welded on the metal ring A2 and the metal ring B3, so that the metal ring A2 and the metal ring B3 respectively serve as the anode and the cathode for charging the mobile phone.

Similarly, the insulation problem between the metal rings a2 and B3 and the casing of the mobile phone is also considered, and when the casing of the mobile phone is made of conductive material, the metal rings a2 and B3 are both adhered to the casing of the mobile phone by the insulating adhesive.

In order to make the distinction more obvious when the power receiving apparatus 6 is docked with the power supply apparatus 5, it is preferable that the width of the metal ring B3 is larger than the width of the metal ring a2, that is, the metal ring B3 is thicker than the metal ring a 2. More preferably, the width of the metal ring B3 is 4mm, and the width of the metal ring A2 is 2 mm.

During the use, only need the casing with the cell-phone and charge 1 butt joints of magnetite on precious shell, during the butt joint, magnetite 1 between them can adsorb together automatically to make metal loop A2 and metal loop A2 contact between them together, metal loop B3 and metal loop B3 contact together, realize the switch-on of circuit, the precious power supply for the cell-phone that charges begins. And after the power supply is finished, the magnet 1 of the mobile phone and the charger are separated. In addition to the wireless charging mode, the normal charging functions of the mobile phone and the mobile phone are still unchanged, and if the mobile phone and the mobile phone want to be charged by using the data line, the mobile phone and the mobile phone can be connected with the charging interface of the existing mobile phone and the charging interface of the mobile phone through the data line.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; those of ordinary skill in the art will understand that: the technical solutions described in the above embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
