Embodiment 1

[0040] In the smart card described in the first embodiment, as Figure 5 As shown, the contactless chip 32 is circuit-connected with the induction antenna 31 and packaged together in the card body layer 30 made of insulating material; for example, the induction antenna 31 is arranged around the contactless chip 32 .

[0041] see figure 1 As shown, taking the case where the sensing area is on the back of the mobile phone as an example, the positional relationship of this part of the mobile phone is the battery 10, the shielding layer 20 of the composite structure, the sensor including the non-contact chip 32 and the sensing antenna 31 from the inside to the outside. Card body layer 30, and mobile phone backplane 40.

[0042] Such as figure 2As shown, the battery 10 includes a battery body 11 and a packaging layer 12 disposed on the battery body 11 . The outermost part of the battery body 11 is a metal shell; the packaging layer 12 displays text, graphics or a combination th...

Embodiment 2

[0048] The difference in the second embodiment mainly lies in, for example, Image 6 As shown, only the inductive antenna 31 is packaged in the card body layer 30 of the smart card, and the inductive antenna 31 is provided with a contact group 311 drawn out of the card body layer 30, capable of connecting with the card body layer 30 external non-contact chip 32 The electrodes on the antenna are directly or indirectly connected to form a circuit connection between the sensing antenna 31 and the non-contact chip 32 .

[0049] Therefore, in the second embodiment, for the case where the sensing area is on the back of the mobile phone, refer to figure 1 As shown, the mobile phone includes the battery 10 of the composite structure, the shielding layer 20 , the card body layer 30 including the induction antenna 31 , and the back panel 40 of the mobile phone from the inside to the outside. The packaging layer 12 of the battery 10 can be arranged between the battery 10 and the shieldi...

Embodiment 3

[0052] The main difference in the third embodiment is that the battery described is a battery with an NFC structure (hereinafter referred to as an NFC battery). Near-field communication (NFC), also known as short-range wireless communication, is a short-range high-frequency wireless communication technology that allows non-contact point-to-point data transmission between electronic devices; devices with NFC function can be read in active mode. The writing device reads and writes data to other NFC devices or various non-contact chips (not specifically referring to chips in the present invention) based on RFID; while in passive mode, NFC devices are equivalent to ordinary non-contact chips and can be read and written by other NFC devices. read and write device or NFC device to read and write data.

[0053] Such as Figure 7 , Figure 8 The shown NFC battery includes an NFC radio frequency antenna 51 and a shielding layer 20 in addition to the battery body 11 and the packaging ...

Abstract

The invention relates to an intelligent card and mobile terminal battery composite structure arranged in a mobile terminal. A sensing antenna arranged on an intelligent card is packaged in a card body layer, the sensing antenna and a non-contact chip corresponding to the sensing antenna are in circuit connection to form a loop, and therefore data exchange is carried out between an external matched reading-writing device and the non-contact chip through wireless radio frequency recognition. The composite structure is provided with a shielding layer blocking electromagnetic interference signals. The inner side of the shielding layer faces the outer side of a battery. The outer side of the shielding layer faces the inner side of the card body layer. The outer side of the card body layer faces the inner side of a shell of the mobile terminal, and the sensing area arranged on the shell of the mobile terminal corresponds to the position of the sensing antenna in the card body layer. The intelligent card and mobile terminal battery composite structure is simple in structure, convenient to carry and suitable for complex electromagnetic source interference environment.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to a composite structure of a smart card and a mobile terminal battery. Background technique [0002] Contactless smart cards have been widely and massively used in various fields such as urban transportation, finance, social security and other payment, information storage and identification. [0003] In order to make life and travel faster, people are eager to combine various contactless smart cards with mobile phones or other mobile terminals for easy carrying. However, the existing common non-contact smart cards do not have the conditions to be used in the complex electromagnetic wave interference environment in the field of high frequency and weak current after being integrated with modern digital electrical equipment. The reason is that the higher the frequency of the signal, the easier it is to radiate out, and the general signal line has no shielding layer, and these signal lines ...
