These embodiments may, however, be embodied in different forms and should not be construed as limiting the scope of the utility model. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the utility model to those skilled in the art.
The embodiments of the present invention will be further clearly and completely described in the following with reference to the specific embodiments.
Referring to fig. 1, fig. 1 is an external schematic view of a wireless charging positioning input system according to the present invention. In practical use, the wireless charging input device 200 can be used for touch input on the touch panel 100, the touch panel 100 can also be used for charging the wireless charging input device 200, the voltage of the wireless charging input device 200 can be increased, and the stable operating voltage of the wireless charging input device 200 can be provided.
Referring to fig. 2, fig. 2 is a schematic diagram of the present invention. The wireless positioning input system can be applied to a wireless positioning pen, a wireless mouse and other wireless pointer equipment, and is not limited in application. When the wireless charging input device 200 moves in the sensing range of the touch panel 100, the wireless charging input device 200 continuously receives the frequency signal Sf transmitted by the touch panel 100. After the wireless input device 200 receives the frequency signal Sf sent by the touch panel 100, electromagnetic induction is performed according to the frequency signal Sf, so as to generate operation power of the wireless charging input device 200, and then the wireless charging input device 200 also sends an induction signal SS to the touch panel 100 as a corresponding positioning signal, so that the touch panel 100 calculates a corresponding position of the wireless charging input device 200 according to the induction signal SS. The power supply required by the operation of the common wireless positioning component on the market mainly uses two modes to obtain power supply: one is powered by a disposable battery, and the other is powered by electromagnetic resonance. If the disposable battery power supply mode is adopted, the defect is that the wireless positioning assembly must frequently replace the battery, which is very inconvenient and environmentally-friendly for users. Therefore, the electromagnetic resonance method is the most suitable power supply method at present, and the technique is well known to those skilled in the art, and will not be described herein.
The touch panel 100 includes a signal processing circuit 110, a charging antenna coil 120, and a demagnetization antenna coil 130. Wherein the signal processing circuit 110 is communicatively connected to the charging antenna coil 120 and the demagnetizing antenna coil 130, and generates the frequency signal Sf. The signal processing circuit 110 transmits the generated frequency signal Sf to the charging antenna coil 120, and after receiving the frequency signal Sf, the charging antenna coil 120 transmits the frequency signal Sf to the wireless charging input device 200. In addition, the demagnetizing antenna coil 130 is used to receive an induction signal SS transmitted by the wireless charging input device 200, wherein the induction signal SS is a signal for positioning the wireless charging input device 200.
The wireless charging input device 200 comprises a mandrel 210, a rectifying circuit 220 and a sensing circuit 230; the core rod 210 has an induction coil 211 and an oscillation circuit coil 212. The rectifying circuit 220 is electrically connected between the induction coil 211 and the induction circuit 230, and the induction circuit 230 is electrically connected between the rectifying circuit 220 and the oscillating circuit coil 212. In addition, the mandrel 210 is a metal mandrel, including but not limited to a powdered iron core. The two ends of the induction coil 211 are further coupled to the first capacitor C1, and can receive the frequency signal Sf transmitted by the charging antenna coil 120, since the induction coil 211 is a coil wound on the outer surface of the metal conductor mandrel, the induction coil 211 can generate an induced voltage by the change of magnetic flux, which is a principle of electromagnetic induction or magnetic coupling (mutual inductance coupling), and the principle is well known to those skilled in the art and will not be described herein again.
When the wireless charging input device 200 is used, the wireless charging input device 200 moves within the induction range of the touch panel 100, and at this time, the induction coil 211 on the mandrel 210 performs electromagnetic induction through the frequency signal Sf to generate a magnetic coupling signal and output electric energy to the rectifying circuit 220, and after the rectifying circuit 220 receives the electric energy, the alternating current is converted into direct current and is transmitted to the induction circuit 230. After the sensing circuit 230 receives the power output by the rectifying circuit 220, it outputs a sensing signal ss to the oscillating circuit coil 212. The two ends of the oscillator coil 212 are coupled to the second capacitor C2, and are used to transmit the sensing signal SS to the touch panel 100, and the demagnetizing antenna coil 130 of the touch panel 100 receives the sensing signal SS as a signal for positioning the wireless charging input device 200.
In addition, the present invention may further have the following variations, please refer to fig. 3, wherein fig. 3 is a schematic structural diagram of another embodiment of the present invention. In this embodiment, an energy storage capacitor Cp may be further disposed between the rectifying circuit 220 and the sensing circuit 230, such that the energy storage capacitor Cp is electrically connected to the rectifying circuit 220 and the sensing circuit 230. When the rectifying circuit 220 outputs the electric energy to the sensing circuit 230, the energy storage capacitor Cp can store part of the electric power passing through, so as to achieve the effect of storing the electric energy. The advantage of this embodiment is that when the wireless charging input device 200 is not in the sensing range of the touch panel 100, the sensing circuit 230 still has operating power.
In summary, the wireless charging positioning input system and the wireless charging input device of the present invention have the following advantages: (1) the touch panel can accurately position the induction signal output by the wireless charging input device; (2) the touch panel can charge the wireless charging input device; (3) increasing the voltage of the wireless charging input device to provide a stable operating voltage for the wireless charging input device; (4) when the wireless charging input device is not in the sensing range of the touch pad, the sensing circuit still has operating power; (5) the core rod is used for fixing the induction coil and the oscillation circuit coil, so that the problems of electromagnetic compatibility and noise wave reduction can be solved, and the advantages of electromagnetic induction enhancement, more electric energy generation, easier induction signal transmission and the like can be realized.
Although the present invention has been shown and described with reference to particular embodiments thereof, the present invention has been described in detail, but is not limited thereto, and various changes, omissions and additions to the form and detail thereof, may be made therein, without departing from the spirit and scope of the utility model. It should be noted that other possible and simple modifications still fall within the scope of the present invention.
