Wireless charging device and charging method thereof

Abstract

The invention relates to a wireless charging device and a charging method thereof, which are mainly used for charging electric equipment in an electromagnetic induction way by a wireless charging seat. The wireless charging sear is periodically started to judge whether the electric equipment enters an induction range or not; once the electric equipment enters the induction range, a transmission coil of the wireless charging seat transmits electromagnetic waves, a receiving coil of the electric equipment induces the electromagnetic waves to generate current and performs switching-on or switching-off according to a given built-in time sequence to relatively change the consumption current of the transmission coil in the wireless charging seat; and then the wireless charging seat judges the change time sequence of the consumption current is consistent with the built-in time sequence or not, and the transmission coil continuously charges the electric equipment if the change time sequence of the consumption current is consistent with the built-in time sequence, and stops charging the electric equipment if the change time sequence of the consumption current is inconsistent with the built-in time sequence. Therefore, the damages caused by different voltage designing of the wireless charging seat and the electric equipment are prevented, and safety in use is ensured.

Description

technical field [0001] The present invention relates to a wireless charging device and a charging method thereof, in particular to a wireless charging device with an identity authentication mechanism and a charging method thereof, which can effectively filter wireless charging stands with different voltage designs to be matched with electrical equipment, so as to Make sure it's safe to use. Background technique [0002] The wireless charging mechanism formed by electromagnetic induction technology is known, and it has been widely used in various daily necessities or computer-related equipment. The most common daily necessities are electric toothbrushes. Since toothbrushes are often exposed to water, they must have good waterproof measures. Therefore, the electric toothbrush is completely airtight with respect to the shell, and it is inserted on the charging stand when charging, and is charged by electromagnetic induction. As for the computer peripheral equipment, the wirele...

[0010] Furthermore, it can be seen from the specification of the above-mentioned published patent case that the receiving module uses an RFID reader to receive the aforementioned authentication code, which means that the handheld device that sends the authentication code must be equipped with an RFID electronic tag to send and receive signals. However, the use of RFID requires Adding additional related components will inevitably increase the manufacturing cost, so it is not yet feasible

From the above, it can be seen that the wireless charging method has its advantages, but in terms of safety, it is indeed necessary to control the use authority. However, the RFID authentication technology implemented in the above-mentioned published patent case involves the additional use of specific components, and there is a cost. consideration
