CHARGING SYSTEM FOR ELECTRONIC DOORLOCK BY USING WIRE-FREE ELECTRIC POWER CHARGING METHOD

摘要

A system for charging an electronic doorlock by using a noncontact charging method is provided to be easily connected to the external power by constructing the charging device at the supporting plate installed on the sidewall. A system for charging an electronic doorlock by using a noncontact charging method includes a charging device(4), a primary magnetic induction unit(21), a noncontact charging electric lock(11), and a charging battery pack(3). The charging device(4) generates the charging power by using the alternative power inputted from the outside and supplies the charging power to the primary magnetic induction unit(21). The primary magnetic induction unit(21) accumulates the energy by the charging power and supplies the accumulated energy to the secondary side in the noncontact method. The noncontact charging electric lock(11) receives the energy from the primary magnetic induction unit(21) in a noncontact method. The charging battery pack(3) is charged by the energy transmitted from the noncontact charging electric lock(11).
