Example Embodiment

[0033] Example one

[0034] Such as figure 1 In the illustrated embodiment, the first connecting structure 1 includes a first connecting portion 11 and a second connecting portion 12. The induction coil 3 is installed in the first connecting portion 11; the first connecting portion 11 and the second connecting portion 12 Through the connection of the first switching portion 4, the first connecting portion 11 can rotate with respect to the second connecting portion 12 with the first switching portion 4 as a connection point, so that the first connecting portion 11 and the second connecting portion 12 have Included angle. Such as figure 2 In the example shown, three second switching parts 5 are installed on the second connection structure 2, and one NFC chip is installed in each of the second switching parts 5. It should be noted that the second connection structure 2 is installed with 3 The number of second switching parts 5 is only an embodiment, and the number of second switch...

Example Embodiment

[0037] Embodiment two

[0038] As a modification of the first embodiment, the structural components are the same as those of the first embodiment. The difference is that the second connecting portion 12 is fixed, and the second connecting structure 2 as a whole can be clockwise or counterclockwise relative to the second connecting portion 12 Rotate so that the second switching part 5 and the first switching part 4 can move relatively. When the first switching part 4 is connected to one of the second switching parts 5, the NFC chip corresponding to the second switching part 5 start up. Other structural components and principles are similar to those of the first embodiment, and will not be repeated here.

Example Embodiment

[0039] Embodiment three

[0040] Such as Figure 5 In the example shown, the second connecting structure 2 is a hard insulating planar structure, which can be made of hard plastic and other materials. The first connecting structure 1 is a flexible insulating structure, which can be made of soft cloth or leather. The induction coil 3 is installed in the second connection structure 2. It can be understood that the two ends of the induction coil 3 are placed in the interlayer of the first connection structure 1. The second connection structure 2 is provided with a rail 7, the first connection structure 1 is provided in the rail 7, one end of the first connection structure 1 is a first fixed end 13, and the other end is a first free end. At the end 14, the first fixed end 13 is fixedly connected to the second connecting structure 2, and the first free end 14 can move along the track 7, thereby driving the first switching portion 4 along the track 7. Moving, the second switching par...

Abstract

The invention relates to an NFC device which comprises a first connecting structure and a second connecting structure, and the first connecting structure and the second connecting structure are connected. An induction coil is installed in the first connecting structure or the second connecting structure, the two ends of the induction coil are connected with first switching parts, and the first switching parts are installed on the first connecting structure. At least one second switching part is mounted on the second connecting structure, and an NFC chip is mounted in each second switching part; wherein the second switching part and the first switching part can move relatively, and when the first switching part is connected with any one of the second switching parts, the NFC chip corresponding to the second switching part is started. According to the NFC device, the NFC chip is convenient to carry and use.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to an NFC device. Background technique [0002] At present, most high-end models in the mobile phone market have been equipped with near-field communication NFC (Near Field Communication, NFC for short) chips, but most low-end phones and old models do not have NFC functions; Corresponding NFC function. However, for NFC cards such as community access cards and bus cards whose chips have been encrypted, mobile phone NFC cannot be directly simulated, so users need to carry one or more NFC cards with them, and NFC cards are usually small and easy to lose. Contents of the invention [0003] The purpose of the present invention is to provide an NFC device, which makes the NFC chip easy to carry and use. [0004] An embodiment of the present invention provides an NFC device, including a first connection structure and a second connection structure, and the first connection ...
