New Description: [New Technology Field] This creation is a sensor module shared by near field communication and wireless charging, especially for a wireless charging (WLC) used in portable devices. Inductive module and Near Field Communication (NFC) sensor module integrated structure β [Prior Art] Press, in portable electronic devices such as mobile phones, PDA (personal digital assistant), palm-sized computers, Notebooks or tablets, etc., are all powered by batteries, so that users can use them when there is no mains power, and these electronic devices will be equipped with a wired power supply to facilitate battery charging or power supply. The new wireless charging (WLC) technology allows portable devices to use no power lines, but can use electromagnetic induction to directly transfer power to the portable devices to charge the battery. As shown in FIG. 1 , it is a schematic diagram of a wireless charging transmission, including a power transmission module 10 and a power receiving module 20 . The power transmission sensing module 10 has a transmitting end coil 11 and a transmitting end core plate. 12, the power receiving sensing module 20 also has a receiving end coil 21 and a receiving end core plate 22. When the power receiving module 20 is close to the power transmitting module 10, a current flows through the transmitting end coil 11 of the power transmitting sensing module 10 to generate a magnetic field, so that the 3 M424550 power receiving sensor _21 senses The magnetic field generates a current. In addition, it is also highly valued to combine near-field communication (NFC) in portable electronic devices. Near-field ship (NFC) Lin allows portable devices to perform non-contact point-to-point communication and provide a highly connected connection. Communicate quickly and easily. Near Field Communication (NFC) technology is evolved from the integration of non-contact radio frequency identification (workmanship) and interconnection technology. In the current field of field communication (the application of muscles, such as the use of traffic jams) Card, as long as the proximity card is close to the MRT ticket π can quickly clear 'and the induction time is faster than the general non-contact crystal > {card, which is quite useful for high-correction traffic stations. Therefore, some people have proposed The near field communication chip is embedded in a portable electronic device such as a mobile phone, and thus the integration of wireless charging (WLC) and near field communication (NFC) functions of the portable electronic device will be an inevitable trend in the future. The two circuits (NFC) and wireless charging transmission (WLC) are completely different and independent. They must use their respective sensing modules to receive different signals. This is an increasingly light and short internal space for portable electronic devices. In other words, the integration difficulty is quite high. The creators of this case found that both the near field communication (NFC) and wireless charging transmission (WLC) technologies are short-range inductive transmission signals, so the coil sensing module is required, and the two The sensing module is not used at the same time, so an integrated near field communication (NFC) and wireless charging (WLC) are designed. 4 The first sensing plate 31 is flat-shaped, which can be direction, rectangular, circular or circular. The first coil 32 is wound into a planar hollow shape, and is disposed on the first sensing plate 31, and has two outlet ends 321 , and the first coil 33 is also secretly wound into a hollow plane shape. The first sensing plate 31 is received in the central hollow of the first coil 32, and is concentric with the first coil 32. The first coil 32 and the second coil 33 are provided. A gap is formed between the embodiments. As shown in the second embodiment, the first coil 32 is a near field communication (NFC) induction coil, and the second coil is a wireless charging (WLC) sense circle. FIG. 4 is a schematic diagram of a second embodiment of the present invention, wherein the first coil is 32% of the wireless charging (WLC) induction coil, and the second coil 33 is the near field m (NFC) induction coil. The first coil 32 and the second coil 33 are two sets of induction coils of different frequency signals, near field The frequency of the induction coil is higher, so the coil is shorter, and the frequency of the wireless charging induction coil is lower, so the coil is longer. The two sets of induction coils can be automatically selected by an automatic selection circuit to determine the induction receiving frequency of the induction coil. A plurality of inductive coils are electrically connected to each other. Since the selection circuit is not the focus of the present invention, it will not be described again. Referring to FIG. 3 again, the common sensing module 30 further includes a non-conductive adhesive layer 35 disposed thereon. The first sensing plate 31 and the first and second coils 32 and 33 are used to adhere the first and second coils 32 and 33 to the first sensing plate 31, preferably the non-conductive adhesive layer. The common sensing module 30 further includes a second sensing plate 34 disposed on the first sensing plate 31 and accommodated in the central hollow of the second coil 32. The non-conductive adhesive layer 35 is also disposed between the first sensing plate 31 and the second sensing plate 34 for bonding the second sensing plate 34 to the first sensing plate 31. Preferably, the first sensing plate 31 is integrally formed with the second sensing plate 34 in a convex shape (not shown), and the convex portion is received in the central hollow of the second coil. Referring to Figure 5, there is shown a schematic view of a third embodiment of the present invention, in which the first coil 3 2 and the second coil 33 abut each other without a gap. Referring to the first embodiment of FIG. 2, two sets of lead-out connector % are respectively disposed at the outer edge of the first sensing board 31 of the common sensing module 3, and each of the lead-out connectors 36 is provided. There are two metal connection terminals 361, which can respectively electrically connect the two outlet ends 321 of the first coil and the two outlet ends 331 of the second coil. Referring to the second embodiment of FIG. 4, only one set of lead wire connectors 36 are disposed at the outer edge of the first sensing plate 31 of the common sensing module 30, and a plurality of metal connecting terminals 361 are disposed thereon, which can respectively be respectively The outlet ends of the first coil and/or the second coils 32, 33 are connected. Alternatively, the lead wire connector 36 may be a metal contact piece 37', for example, the wire end 331 of the second coil 33 may be electrically connected to the metal contact piece 37 respectively. Referring to the third embodiment of FIG. The lead wire connector 36 is a connector disposed outside the first sensor board 31, and the metal connection terminal 361 has two metal connection terminals electrically connected to a total of M424550.
