Embodiment 1

[0046] figure 1 It is a schematic structural diagram of a wireless charger that can prompt for position adjustment provided by Embodiment 1 of the present invention. The wireless charger generates electromagnetic waves through the transmitting coil, and the receiving coil converts the electromagnetic waves into electrical energy through electromagnetic induction to charge the implanted device. Such as figure 1 As shown, the wireless charger includes: a driver 1, used to generate a high-frequency waveform signal of 30KHz to 80KHz, and the above functions can be realized by a corresponding chip or a high-frequency oscillator circuit and a power amplifier circuit; a resonant circuit 2, used for Generate and radiate electromagnetic waves according to high-frequency waveform signals; the prompt module 3 is used to prompt the user to move the wireless charger;

[0047] In this embodiment, the driver chip U1 is used as the driver 1 of the wireless charger, which is used to output h...

Embodiment 2

[0056] This embodiment is optimized based on the above embodiments, wherein the voltage obtaining unit 4 obtains the voltage of the inductance coil L2 in the resonant circuit. Figure 5 It is a schematic diagram of the connection of the voltage acquisition unit in the in vitro wireless charger that can prompt to adjust the position provided by the second embodiment of the present invention. Figure 5 It can be seen that the voltage acquisition unit 4 is used to transmit the voltage across the coil L1. The voltage acquiring unit 4 is electrically connected to the transmitting coil L1 in the resonant circuit, and can acquire the voltage of the transmitting coil L1. And it can be determined whether the location of the wireless charger is suitable for charging the implanted device according to the voltage of the transmitting coil L1.

Embodiment 3

[0059] Figure 7 It is a schematic flow chart of the prompt method for adjusting the position of the wireless charger according to Embodiment 3 of the present invention. The prompt method for adjusting the position of the cord charger can be based on the wireless charger that can prompt for position adjustment provided in the above-mentioned embodiment.

[0060] see Figure 7 , the prompt method for adjusting the position of the wireless charger includes:

[0061] Step 310, the driver generates a high frequency waveform pattern.

[0062] Step 320, the resonant circuit generates and radiates electromagnetic waves according to the high-frequency waveform signal generated by the driver.

[0063] In step 330, the voltage of the resonant circuit is obtained by the voltage obtaining unit.

[0064] Step 340, comparing the voltage of the resonant circuit obtained by the voltage obtaining unit with the reference voltage, and outputting a prompt through the prompting device when abno...

Abstract

Embodiments of the invention disclose a wireless charger capable of prompting position adjustment, a prompting method and chargeable implantable medical equipment. The wireless charger comprises a driver used for generating a high-frequency waveform signal, a resonance circuit used for generating and radiating electromagnetic waves according to the high-frequency waveform signal, and a prompting module used for prompting a user to adjust the position of the wireless charger when abnormal charging of the wireless charger is detected, wherein the driver is connected with the resonance circuit; and the prompting module is connected with the resonance circuit. Whether the current position of the wireless charger is a proper position or not can be detected according to the voltage changes on one side of the charger in wireless charging; prompting can be sent to the user when the wireless charger is in an improper position, so that the user can adjust the position of the wireless charger according to the prompting so as to avoid the problem that the implantable equipment is relatively far from the wireless charger and cannot be charged; and therefore, the charging quality and efficiency of the implantable equipment are improved.

Description

technical field [0001] The invention relates to the technical field of wireless chargers, in particular to a wireless charger capable of prompting for position adjustment, a prompting method, and a rechargeable implantable medical device. Background technique [0002] Wireless charging technology originates from wireless power transmission technology. Wireless charging, also known as inductive charging, non-contact inductive charging, uses near-field induction, that is, the coupling of the transmitting coil, and the power supply equipment (charging sending device, such as a charger) transmits energy to the power-consuming device (charging receiving device) device, such as a mobile phone), that uses the received energy to charge the battery and simultaneously use it for its own operation. Since the charging transmitting device and the charging receiving device are coupled to transmit energy by the transmitting coil, the two are not connected by wires, so the charger and the ...
