Detailed Description

In order to more fully understand the technical content of the present invention, the technical solution of the present invention will be further described and explained with reference to the specific embodiments.

First embodiment

The first embodiment is a wireless sensing receiving patch, as shown in fig. 1. The wireless induction receiving patch comprises a plug 15, a circuit board 13 and a wireless receiving coil 11 for receiving electromagnetic waves. The plug 15 and the circuit board 13 are electrically connected through the flexible circuit board 14, and the circuit board 13 is electrically connected with the wireless receiving coil 11. The plug 15 is used for being plugged in a charged device and transmitting the electric energy formed by the wireless receiving coil 11 to the charged device. In specific implementation, the plug 15 may be one of a Type-C plug, a Micro-USB plug, and a Lightning plug, so as to meet the requirements of various users having different devices.

As shown in fig. 1, 4 magnet pieces 12 are provided at intervals around the wireless receiving coil 11. The thickness of the magnet piece 12 should not be larger than 2mm, such as 1mm, to avoid the excessive thickness of the whole wireless sensing receiving paste. The magnet piece 12 is used for producing magnetic attraction with the magnet piece around the wireless transmitting coil on the external charging module so as to align the wireless receiving coil 11 to the wireless transmitting coil, namely, the magnetic attraction can be used for attaching the wireless sensing receiver to the optimal charging position automatically positioned by the charging device, thereby avoiding the user from manually adjusting the position of the charged device. In this embodiment, four magnet pieces 12 are uniformly distributed around the wireless receiving coil 11. In other embodiments, only 2 or 3 magnet pieces can be arranged, but the magnetic attraction force is relatively weakened, and the automatic positioning effect is reduced. In other embodiments, more than 4 magnet pieces may be provided to enhance the magnetic attraction, but the overall cost is increased. In other embodiments, the magnet pieces may be replaced by ferromagnetic pieces, such as iron pieces.

As shown in fig. 1, the wireless induction receiving patch clamps the wireless receiving coil 11, the circuit board 13, the magnet piece 12 and a part of the flexible circuit board 14 through the front and rear film pieces 16, thereby preventing scattering of parts. The film sheet 16 may be made of a thin material, such as synthetic paper material. The outer side of one of the thin film pieces 16 can be coated with adhesive or pasted with double-sided adhesive, so that the wireless sensing receiving paste is fixed on the back of the charged device.

Second embodiment

A second embodiment is a charging device. As shown in fig. 2, the charging device includes the wireless sensing reception patch 10 of the first embodiment and a charging module 20. The charging module 20 is internally provided with a wireless transmitting coil 21, 4 magnet blocks 22 are arranged around the wireless transmitting coil 21, and the arrangement of the magnet blocks 22 corresponds to the arrangement of the magnet pieces in the wireless induction receiving patch 10. When the wireless induction receiving sticker 10 is used, the wireless induction receiving sticker 10 is tightly attached to the back of a charged device, the plug 15 is inserted into the charged device, then the charged device is placed on the charging module 20, then the magnetic attraction force of the magnet block 22 and the magnet pieces positions the wireless induction receiving sticker 10 and the charged device until the wireless transmitting coil 21 is aligned with the wireless receiving coil, and the charged device can be wirelessly charged after the charging module 20 is connected with a power supply.

The above description is only for the purpose of illustrating the technical content of the present invention by way of example, so as to facilitate the understanding of the reader, but does not represent that the embodiments of the present invention are limited thereto, and any technical extension or re-creation according to the present invention is protected by the present invention.
