DETAILED DESCRIPTION OF THE INVENTION

Please refer toFIG. 4. The instant disclosure provides an electronic device8which can accept wireless power supply. When the electronic device8is disposed on a wireless power supply panel9, the electronic device8is powered.

Please refer toFIG. 1in conjunction withFIG. 2. The electronic device8includes a main body80and a wireless power supply device1. The wireless power supply device1is disposed in the main body80and a portion thereof is exposed to the exterior. In the instant embodiment, the main body80is a pet like toy. The main boy80includes a microprocessing unit82, an execution unit84and a signal receiving unit83. The toy receives external signals, for example, sound, temperature or contacting, through the signal receiving unit83. Then the signal receiving unit83passes on the signal to the microprocessing unit82which commands the execution unit84. The pet like toy responds according to external stimuli. The responses include blinking, making noise, moving or the like. The responses may vary according to design requirement and the instant disclosure is not limited thereto. The main body80may also be a mouse, a robot or a telephone that requires constant power supply when resting on a surface.

The main body80defines a power receiving compartment81which is close to the wireless power supply panel9. An anode811and a cathode812are disposed in the power receiving compartment81. The position of the anode811and the cathode812is configured according a conventional battery layout. The power receiving compartment81is accessed through an opening813, such that the wireless power supply device1can be placed in the power receiving compartment81.

Please refer toFIGS. 1 and 2. The wireless power supply device1includes a wireless power receiver10and a shell20. The wireless power receiver10is connected to the shell20. The wireless power receiver10includes a circuit board11and a sensing coil12. The sensing coil12is electrically connected to and disposed on one side of the circuit board11. The circuit board11has two wires111. The two wires111respectively allow connection with provide positive voltage and negative voltage.

The shape of the shell20conforms to the power receiving compartment81and can be put therein via the opening813. The shell20is made of insulation material, for example, plastic, such that a user does not get electrical shock when installing the shell20. The shell20is formed with a wire hole23and an anode portion21and a cathode portion22. When mounted in the power receiving compartment81, the anode portion21corresponds to the anode811while the cathode portion22corresponds to the cathode812. In the instant embodiment, the power receiving compartment81is designed to receive alkaline battery, and therefore the shell20resembles a conventional alkaline battery which is a cylindrical tube and the anode portion21and the cathode portion22are arranged at the opposite side of the shell20. The wire hole23is formed on the tube body of the shell20.

The two wires111of the circuit board11go through the wire hole23, such that the anode end and the cathode end of the wires111are received by the shell20and correspond to the anode portion21and the cathode portion22of the shell20. In the instant embodiment, metal sheets211,212are disposed on the outer side of the anode portion21and the cathode portion22. The two wires111go through the shell20and contact the two metal sheets211,212, such that electricity channels are established to the anode portion21and the cathode portion22. The wires111may also go through the shell20and arranged on the outer side of the anode and cathode portions21,22. The instant disclosure is not limited to the abovementioned configuration. Alternatively, the two wires111may also wrap along the shell20and reach the anode portion21and cathode portion22respectively.

Please refer toFIG. 3. In another embodiment of the instant disclosure, the power receiving compartment81is shaped as a button battery. As a result, the shell20resembles a conventional button battery like a coin. The cathode portion22is arranged on one side of the shell20while the anode portion21is arranged on the remaining surface of the shell20. The wire hole23is formed on the other side of the shell20.

Attention is now invited toFIGS. 1 and 2. The wireless power supply device1is disposed in the power receiving compartment81of the main body80. The opening813provides the access to the power receiving compartment81. The wireless power receiver10is disposed between the outer cover30and the main body80. The outer cover30closes up the opening813, such that the power receiver10is secured within the power receiving compartment81. The outer cover30is fastened to the main body80by bolts or screws. The circuit board11may have an attachment portion112on the side facing the outer cover30. Then the outer cover30can be attached to the circuit board11. Furthermore, the circuit board11of the power receiver10may be configured to block the opening813. In this regard, the circuit board11replaces the outer cover30and functions as an electrical component and a cover at the same time.

Please refer toFIG. 4. When the electronic device8is disposed on the wireless power supply panel9, the sensing coil12generates electrical current because of the electromagnetic effect between the power supply panel9and the sensing coil12. The electrical current generated by the sensing coil12goes through the circuit board11, wires111to the anode portion21and the cathode portion22of the shell20and finally to the anode811and cathode822in the power receiving compartment81. The power is then provided to the microprocessing unit82, execution unit84and signal receiving unit83of the main body80.

In short, the wireless-powered electronic device and the wireless power supply device of the instant disclosure provide the following advantages. The shell can be adapted to various dimension of the power receiving compartment, such that the electronic device does not need to be remodeled. The wireless power supply module can replace the existing power supply mode. The sensing coil is exposed, and therefore the sensitivity is higher.
