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.

The embodiment of the utility model provides a wireless receipt subsides 100 that charge, its concrete structure is shown in fig. 1-3.

Fig. 1 is an assembled perspective view of a wireless charging reception sticker 100. The wireless charging receiving sticker 100 is used for being tightly attached to the back of a device to be charged. The wireless charging receiving patch 100 includes a plug 14. The plug 14 in fig. 1 is connected by a flexible circuit board 13. The plug 14 in fig. 1 is a Micro-USB plug that can be plugged into a Micro-USB female port in a bi-directional manner. The plug 14 is used for plugging a Micro-USB female port of a charged device and transmitting electric energy to the charged device.

As shown in fig. 2, the metal shell 141 of the header 14 has a flat rectangular cross section, four outer corners are provided with chamfers 142, and adjacent chamfers 142 are symmetrical to each other. The structural design of the four outer corners is the chamfer shape design which is adapted to the Micro-USB female port, so that when the plug 14 is inserted into the Micro-USB female port from one of two directions, the two chamfers 142 of the metal shell 141 of the plug 14 are correspondingly attached to the two chamfers on the inner side of the metal shell of the Micro-USB female port, and the plug 14 can be well fixed after being completely inserted.

As shown in fig. 2, a plate-shaped terminal block 143 is provided in the middle of the inner cavity of the plug 14. The plane of the terminal base 143 is parallel to the plugging direction of the plug 14 and the length direction of the section of the plug 14. The outer sides of both sides of the terminal base 143 are provided with a narrow space 144 for inserting the tongue of the Micro-USB female port. The terminal base 143 has symmetrical terminal sets 145 on both sides. The terminal group 145 is composed of 5 metal terminals arranged side by side in an equidistant manner. The terminal group 145 is used for correspondingly communicating with a terminal group on a plug tongue of the Micro-USB female port in a contact mode. The terminal sets 145 are symmetrically arranged on two sides of the terminal base 143, so that when the plug 14 is inserted into the Micro-USB female port from one of two directions, the terminal sets of the plug tongue of the Micro-USB female port can be always in contact communication with one of the terminal sets 145 on the terminal base 143, and therefore the plug 14 in the two-way plug connection can be effectively electrically connected with the Micro-USB female port.

As shown in fig. 3, the wireless charging receiving patch 100 further includes a wireless receiving coil 11 for receiving electromagnetic waves and a circuit board 12. The plug 14 is electrically connected to the circuit board 12 through the flexible circuit board 13, and the circuit board 12 is electrically connected to the wireless receiving coil 11. The electric energy formed by the wireless receiving coil 11 is transmitted to the plug 14 through the circuit board 12, and then transmitted to the charged device through the plug 14. Around the wireless receiving coil 11, 4 magnet pieces 15 are provided at intervals. The magnet piece 15 is used for producing magnetic attraction with the magnet piece around the wireless transmitting coil on the external charging module so as to position the wireless receiving coil 11 to the wireless transmitting coil, that is, the wireless charging receiving paste 100 and the charged device are automatically positioned to the optimal charging position through the magnetic attraction, thereby avoiding the user from manually adjusting the position of the charged device. The thickness of the magnet piece 15 in this embodiment is not more than 2mm, such as 1mm, and it is avoided that the overall thickness of the wireless charging receiving sticker 100 is too large. In this embodiment, there are four pieces of the magnet 15, which 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.

Further, as shown in fig. 3, a magnetic shield 18 is attached to the side of the radio receiving coil 11. The magnetism isolating sheet 18 plays the roles of magnetic conduction, magnetism blocking and heat conduction. Four notches 181 are formed on the outer edge of the magnetic shielding sheet 18. The magnet piece 15 is placed in the notch 181. The breach 181 is used for fixing a position magnet piece 15 for every wireless charging receives magnet piece 15 position of pasting 100 and all is unanimous, has avoided magnet piece 15 offset and has leaded to the not enough of magnetic attraction.

As shown in fig. 3, the wireless charging receiving patch 100 is configured to prevent scattering of parts by adhering the wireless receiving coil 11, the circuit board 12, the magnet piece 15, and a part of the flexible circuit board 13 via the front and

rear films

16 and 17. The

film sheets

16, 17 may be made of a thin material, such as synthetic paper material. The outer side of one of the thin film sheets 17 may be coated with an adhesive or attached with a double-sided adhesive, so that the wireless charging receiving sticker 100 is fixed on the back of the device to be charged.

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.
