In order to omit a charger and a connector for connecting the charger in the attached figure 1, the invention discloses a wireless power supply system of a passive accessory of an intelligent terminal, which is directly supplied with power through the intelligent terminal when being matched with the intelligent terminal for use. Referring to fig. 2, the passive accessory is attached to the housing of the intelligent terminal for mutual inductance during operation, the intelligent terminal comprises a wireless receiving and transmitting coil, and the accessory consists of a wireless receiving coil, a current rectifying module, a control module and an execution module. A mutual inductance channel is formed between the wireless receiving coil and the wireless transmitting coil so as to generate a mutual inductance signal. The current rectifying module is used for rectifying the mutual inductance signal into usable current, and then the current is used as a control module and an execution module in the passive accessory to enable the passive accessory to work. The current rectifying module is typically a rectifying circuit.
Specifically, after the intelligent terminal is attached to the passive accessory, mutual inductance is successfully performed between the wireless receiving and transmitting coil and the wireless receiving coil so as to transmit mutual inductance signals. The wireless receiving coil generates a first current according to the mutual inductance signal, the wireless receiving coil is connected with the current rectifying module to transmit the first current to the current rectifying module, and the current rectifying module rectifies the first current into a second current which can be used. So far, the mutual inductance of laminating through intelligent terminal and passive accessory produces the electric current that can supply the passive accessory to use.
The current rectifying module is respectively connected with the control module and the execution module, and the control module is connected with the execution module; the execution module executes the task after receiving the second current, and the control module controls the execution module to execute the task after receiving the second current. That is, even though the execution module may start executing the task after receiving the second current, the control module has a right to control whether the execution module executes the task or which task is executed after receiving the second current.
