Embodiment Construction

[0015] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0016] First of all, according to the principle of physics: when the magnetic field in a coil changes, a current will be induced, and the magnitude of the induced current is proportional to the rate of change of the magnetic field in the coil, which is called Faraday's law. Please refer to Figure 1, according to Lenz's law, we can know that in the figure: (a) the magnetic field in the coil changes, and an induced current is generated; (b) the induced current generates a magnetic field; (c), (d) the directions of the current and the magnetic field are in line with ( a) and (b) are in opposite directions.

[0017] Referring to Figure 2 and Figure 3 again, the wireless charging device for the handheld device includes a charger and charging components on the handheld device, wherein the charger includes a mains AC connection module 1, a transform...

Abstract

The invention is concerned with a wireless charge device of holding equipment. It relates to charge part of charger and holding equipment, while the said charger relates to alternating current connecting module of city electricity, transformer module and alternating current loop module. The alternating current connecting module of city electricity connects with alternating current loop module, and the said charge part of holding equipment relates to induction loop module, commutating module and filter module. The induction loop module connects with commutating module, filter module and cells of holding equipment. The wireless charge device with this structure realizes the wireless charge function of holding device using magnetic induction loop. It is very convenience to user for a wireless charge device fitting for holding devices with different brands, models, charge current and charge voltage. This charge device charges quickly with simple structure and low cost with wide applicability.

Description

technical field [0001] The present invention relates to the field of handheld devices, in particular to the field of charging devices for handheld devices, in particular to a wireless charging device for handheld devices. Background technique [0002] In modern life, handheld devices are used more and more, and the current charging of handheld devices uses the AC power from the mains to be converted into DC by a charger, and then connected to the handheld device through a cable and connector to realize charging. This makes handheld devices of different brands and models use chargers with different currents, different voltages and different connectors, without any universality. The user has no electricity and does not have a suitable charger at hand to charge the device, and is in the embarrassing situation of not being able to make calls. It will be very inconvenient if you carry the charger with you anytime and anywhere. Moreover, often plugging and unplugging the connect...
