The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

Referring to fig. 1, 3, 4 and 5, the present invention discloses a suitcase 10 with a baggage tag, which comprises a suitcase body 100 and a baggage tag 200 disposed on the surface of the suitcase body 100 for indicating the relevant information of the passenger flight, the person and the baggage, the baggage tag 200 comprises a frame 210 having an opening 211 on a main surface thereof, an electronic ink panel 220 received in an inner cavity of the frame 210 and having a display surface corresponding to the opening 211, a PCB 250 mounted on a back of the electronic ink panel 220, and a control unit 230 disposed on the PCB 250, wherein the control unit 230 comprises an MCU circuit 231 having an MCU processor 231a, a data exchange circuit 232 connected to the MCU circuit 231, and a display driving circuit 233 for driving the display of the electronic ink screen 220 under the control of the MCU circuit 231, further comprising a USB interface 232a connected to the MCU processor 231a through the data exchange circuit 232, for taking power from an external electronic device and obtaining data information for display by the electronic ink screen 220. Specifically, when the USB interface 232a is connected to the external electronic device, the external electronic device obtains power and obtains data information, transmits the received data information to the electronic ink screen 220 in the form of an electrical signal, and displays corresponding baggage information on the display surface of the electronic ink screen 220.

The box body 100 is used for accommodating luggage and installing a luggage tag 200, it should be noted that the box body 100 of the present embodiment is the same as a common suitcase sold in the market, and includes a zipper, a coded lock, a hand grip, a pull rod, and the like, and fig. 1 and fig. 2 only show the most basic shape of the box body, and in actual production, other functions and decorative parts can be added according to the consumption requirements of users, and are not described herein again. By arranging the luggage tag 200 on the box body 200, the current flight information can be guided into the MCU processor 231a only by electrically connecting the external electronic device with the USB interface 232a of the luggage tag 200 on the box body 100, and can be displayed on the electronic ink screen 220 instead of using tag paper, so that the flight information can be repeatedly accessed, and the luggage tag is not easy to fall off from the box body 100, thereby being beneficial to effectively identifying luggage for users.

Referring to fig. 1, in an embodiment, the USB interface 232a is disposed at a side of the luggage tag 200, and the luggage tag 200 is disposed at a middle portion of a wider surface of the box 100, in which case, a corresponding abdicating slot 110 is required to be formed at a position on the box 100 adjacent to the USB interface 232a of the luggage tag 200, so that a connector of the data connection line extends into the abdicating slot 110 and is inserted into the USB interface 232 a. Referring to fig. 2, in another embodiment, the baggage tag 200 is disposed on the edge of the wider side of the container body 100. In this case, the opening 211 of the USB interface 232a is not covered by the surface of the case 100, and thus the USB interface 232a can be plugged into the data connection line without opening the recess 110. Of course, in actual production, according to the structure and arrangement of the box 100 itself, the luggage tag 200 may be installed at any other position on the box 100, so that the USB interface 232a is exposed, can be plugged, and is convenient for the user to clearly view the content displayed on the electronic ink screen 220, which is not described herein again.
