In connection with some applications, the luggage card clasp 100 may be a portion that is secured to the luggage case, for example, the luggage card clasp 100 may be secured to the luggage case by a rope or a pendant key fob or the like.

The first passive radio frequency tag 110 may have corresponding tag information, for example, TID value, etc., and the external electronic device may obtain the tag information of the first passive radio frequency tag 110 through wireless communication, but in general, the user needs to read the tag information through the external electronic device, the relationship between the tag information and the luggage is not intuitive, and in the case where there are a plurality of luggage card buckles 100, the tag information displayed by the external electronic device may not coincide with the luggage card information displayed on the display screen of the luggage card body 200. The above problems are solved by the improvement of the structure of the luggage card buckle 100 and the arrangement of the luggage card body 200 in the present embodiment.

Specifically, the line Li Pai buckle 100 in this embodiment further includes a first connection interface 120 connected to the first passive radio frequency tag 110, where the first connection interface 120 may be a wired interface for data transmission, and a communication protocol used by the first connection interface may not be limited specifically, and may be, for example, an integrated circuit bus (Inter-Integrated Circuit, I2C), a serial peripheral interface (Serial Peripheral Interface, SPI), or a universal asynchronous receiver/Transmitter (Universal Asynchronous Receiver/Transmitter, UART), or the like.

The processor 211 may be a micro control unit (Microcontroller Unit, MCU) or a programmable logic controller, etc., which receives related data and controls the display of the data by the display 220, which is not described in detail herein.

Alternatively, the luggage tag body 200 may also include an RFID tag, or a near field communication (Near Field Communication, NFC) tag or the like type of electronic tag, and the processor 211 may be an integral part of the electronic tag.

Through the connection between the first connection interface 120 and the second connection interface 230, the processor 211 can acquire tag information based on a wired communication manner, so that external signal interference is avoided, and further, the problem that tag information (such as TID of an RFID tag) of a desired luggage card buckle 100 cannot be accurately acquired when a plurality of luggage card buckles 100 exist is solved. The display 220 displays the tag information, so that the user can intuitively read the information of the luggage card buckle 100 and the associated luggage, and the requirement on the related reader is reduced.

The electronic luggage card provided in this embodiment of the present application includes a luggage card buckle 100 and a luggage card body 200, where the luggage card buckle 100 includes a first passive radio frequency tag 110 electrically connected with a first connection interface 120, the luggage card body 200 includes a processor 211, and a display screen 220 and a second connection interface 230 electrically connected with the processor 211, and the second connection interface 230 is electrically connected with the first connection interface 120. In this embodiment of the present application, the processor 211 may read the tag information of the first passive radio frequency tag 110 through the second connection interface 230 and the first connection interface 120, and display the tag information through the display screen 220, so that a user can conveniently, accurately and intuitively read the luggage information of the luggage card buckle 100.

The luggage card body 200 is a passive device, i.e., without an energy storage device such as a battery. For example, the luggage card body 200 may include an NFC tag, and the processor 211 of the NFC tag may be an MCU. In this way, after the external device uses the NFC communication mode, the MCU of the luggage card body 200 can activate the MCU to perform related service processing by using the electromagnetic induction mode after the coil (corresponding to the radio frequency antenna 212 in fig. 2 to 4) on the NFC tag device.

Optionally, as shown in fig. 2 to 4, the luggage board body 200 includes a second passive radio frequency tag 210, and the second passive radio frequency tag 210 includes a processor 211 and a radio frequency antenna 212;

in the case that the second passive radio frequency tag 210 is activated by an external electronic device, the processor 211 reads tag information of the first passive radio frequency tag 110 through the second connection interface 230 and the first connection interface 120.

The external electronic device may be a mobile terminal with NFC functionality or a dedicated reader or the like, which may emit a radio frequency signal to activate the second passive radio frequency tag 210, if the external electronic device activates the second passive radio frequency tag 210 via the NFC device, the second passive radio frequency tag 210 is preferably an NFC tag. The rf antenna 212 of the second passive rf tag 210 may generate a current signal under the influence of the rf signal, which may cause the processor 211 in the second passive rf tag 210 to operate such that the second passive rf tag 210 is activated.

In connection with the application of existing control techniques, the processor 211 may read tag information of the first passive radio frequency tag 110, such as TID or electronic code (Electronic Product Code, EPC) of the RFID tag, with the first connection interface 120 through the second connection interface 230, in case the second passive radio frequency tag 210 is activated. In this way, the user can select the display time of the luggage board body 200 to the tag information through the external electronic device, so that the user experience is improved.

The first passive radio frequency tag 110 may be divided into two types, one with an I2C interface and the other without an I2C interface, and these two structures will be described in detail in the following embodiments.

In some embodiments, in the case where the second passive radio frequency tag 210 is preferably an NFC tag, the operation of updating the data of the second passive radio frequency tag 210 is completed by the MCU of the activated NFC tag itself, and the data transmission is completed through the NFC communication protocol.

Optionally, the display screen 220 is an ink screen, and the radio frequency antenna 212 included in the second passive radio frequency tag 210 is electrically connected to the ink screen, and when the second passive radio frequency tag 210 is activated by an external electronic device, the radio frequency antenna 212 supplies power to the ink screen, so that the ink screen can refresh the screen. And in the case where the second passive radio frequency tag 210 is not activated, the ink screen may maintain the display without consuming power.

In some possible embodiments, the ink screen may also display other content, such as pre-stored pictures or text, which may be refreshed when the ink screen is powered by the rf antenna 212.

As shown above, the rf antenna 212 of the second passive rf tag 210 can generate an induced current under the effect of the rf signal, and thus can be used as an equivalent power supply, and for the ink screen, the power of the antenna is smaller, the requirement on the power supply is lower, and the induced current generated by the rf antenna 212 can be used as the power supply of the ink screen, so that the ink screen can be refreshed, for example, the tag signal is refreshed and displayed, so that the rf antenna 212 can have a multipurpose effect, and the size of the luggage board main body 200 can be reduced.

Alternatively, as shown in fig. 2, in one embodiment, the first connection interface 120 includes a first printed circuit board 121 and a first data interface 130 disposed on the first printed circuit board 121, and the second connection interface 230 includes a second data interface 250 that mates with the first data interface 130.

The arrangement of the first printed circuit board 121 can enable the electronic components in the luggage card buckle 100 to be integrated in a modularized manner, thereby improving the production and assembly efficiency.

As described above, the first connection interface 120 may employ an interface based on a communication protocol such as I2C, SPI or UART, or the like. In this embodiment, the first data interface 130 may be a specific interface that samples a communication protocol. Accordingly, to enable a mating connection with the first data interface 130, the second connection interface 230 may include a second data interface 250 that mates with the first data interface 130.

In a preferred embodiment, the first data interface 130 is an I2C interface, which is configured to implement pairing connection and communication through a plurality of pin pins that are flexibly arranged, and has a relatively simple structure. For simplicity of explanation, the first data interface 130 will be mainly described as an I2C interface, and accordingly, the second data interface 250 may also be an I2C interface.

In this embodiment, the first data interface 130 may be separately disposed on the first printed circuit board 121, where the requirements on the first passive radio frequency tag 110 are relatively low, for example, the first passive radio frequency tag 110 may use a common ultra high frequency (Ultra High Frequency, UDF) RFID tag.

Optionally, as shown in fig. 2, the luggage card buckle 100 further includes a first memory 140, where the first memory 140 is disposed on the first printed circuit board 121, the first memory 140 is electrically connected to the first data interface 130, and the first memory 140 is used to store tag information of the first passive radio frequency tag 110.

In this embodiment, the first data interface 130 is directly connected to the first memory 140, and then the processor 211 (e.g. MCU of NFC tag) on the luggage card body 200 may directly read, through the first data interface 130, tag information, such as TID value, of the first passive radio frequency tag 110 set by the first memory 140 in factory setting.

As a variation of the above embodiment, as shown in fig. 3, in one implementation, the first connection interface 120 includes a first printed circuit board 121, and the first passive radio frequency tag 110 is a passive radio frequency tag carrying a first data interface 130, where the first data interface 130 is electrically connected to the first printed circuit board 121.

In combination with the above example in which the first data interface 130 is an I2C interface, in this embodiment, the first passive radio frequency tag 110 may be a special UDF RFID tag having an I2C interface, and in one example, when the second data interface 250 is connected to the I2C interface of the special UDF RFID tag, then the MCU of the NFC tag on the luggage card body 200 may directly read the TID value of the first passive radio frequency tag 110 through this I2C interface.

As for the connection relation and the operation principle of other elements, etc., reference is made to the above embodiment, and a repetitive description is not made here.

In some examples, the first memory 140 may be an electrically erasable programmable read-only memory (Electrically Erasable Programmable read only memory, EEPROM) or other non-volatile storage device.

In some embodiments, when the luggage board body 200 includes the second passive radio frequency tag 210 and the second connection interface 230 includes a second printed circuit board, a second memory (not shown in the figure) may also be disposed on the second printed circuit board, for storing content of a type such as pictures, text, etc., and when the second passive radio frequency tag 210 is activated, the processor 211 may read the content in the second memory and display the content in the ink screen.

Optionally, as shown in fig. 4, the luggage card clasp 100 further includes a first mechanical connector 150, and the luggage card body 200 further includes a second mechanical connector 260; in the case where the first mechanical connector 150 is connected with the second mechanical connector 260, the first connection interface 120 is electrically connected with the second connection interface 230.

In some application scenarios, the luggage card body 200 is not tightly connected to the luggage card buckle 100, and when the luggage is carried or jolted, the luggage card body 200 may be separated from the luggage card buckle 100.

In order to prevent the above situation, in the present embodiment, the firmness between the luggage card body 200 and the luggage card buckle 100 is improved by the first mechanical connector 150 and the second mechanical connector 260, and meanwhile, the first connection interface 120 and the second connection interface 230 are ensured to be electrically connected under the condition that the first mechanical connector 150 and the second mechanical connector 260 are connected, so that the data interaction between the luggage card body 200 and the luggage card buckle 100 can be performed.

In some possible embodiments, the first mechanical connector 150 is detachably connected to the second mechanical connector 260 by at least one of the following structures: the magnetic attraction structure, the rotary connection structure and the buckle structure.

For example, the first mechanical connector 150 and the second mechanical connector 260 may be in a threaded connection, or may be connected by an elastic snap or a rotational snap, or may also be connected by a magnet, or the like. Of course, in some preferred embodiments, the connection may be performed by using a structure such as a screw or a buckle, so as to avoid interference to electronic components such as the first passive radio frequency tag 110.
