[0004] Currently, the smart terminal is basically charged with a conventional split charger. The charging specifications and connector definitions are different, resulting in a large waste of charger and data cable resources, and only one smart terminal can be charged at a time; device charging It is necessary to connect the power supply and the cable when charging, and the cable needs to be plugged and unplugged during the charging process, which is inconvenient for the user experience
[0005] Wireless chargers are beginning to appear in the industry. However, because the number of coils in the transmitting coil and receiving coil is fixed, and the devices that need to be charged have different specifications and power requirements, the charging efficiency of wireless chargers cannot reach the optimum value.

Embodiment Construction
[0026] For a better understanding of the present invention, the present invention will be further described below through examples, which are only used to explain the present invention, and will not constitute any limitation to the present invention.
[0027] Such as figure 1 , a receiving coil for a wireless charger, the receiving coil is formed by stacking a plurality of annular coils 10 in a manner of superimposing inside and outside, and the plurality of stacked annular coils are located on the same plane. Protruding joints 101 are provided on the outer wall of each toroidal coil, and recessed joints 102 are provided on the inner wall of each toroidal coil; the protruding joints of the inner ring coils are embedded in the recessed joints of the outer ring coils , the protruding joint of the outermost layer and the pit joint of the innermost layer are connected to external wires; the number of the plurality of toroidal coils is more than two, and the toroidal coil (10) incl...

The invention discloses a receiving coil for a wireless charger. The receiving coil is formed by overlapping a plurality of annular coils by an inner and outer overlapping manner; a convex joint is arranged on the outer sidewall of each annular coil; a concave pit joint is arranged on the inner sidewall of each annular coil; the convex joint of the annular coil at the inner layer is embedded into the concave pit joint of the annular coil at the outer layer; the convex joint at the outermost layer and the concave pit joint at the innermost layer are connected with external conductors; more than two annular coils are arranged; the convex joints are externally coated with nano ferroferric oxide layers. According to the technical scheme, the receiving coil is formed by overlapping the plurality of (at least two) annular coils; the annular coils can be conveniently added and removed; the quantity of the annular coils can be adjusted as requirement, so that the transformation ratio of an emission coil to a receiving coil can be adjusted; therefore, the charging efficiency can reach the optimal value when charging devices of different specification and power by the wireless charger.
