[0011] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0012] The specific technical solution of this utility model is as follows: like Figures 1 to 6As shown, this utility model provides an electronic paper name tag, including: a main housing 1, an electronic paper display screen 2 disposed on the front side of the main housing 1, a circuit board 3 disposed in the main housing 1 and located inside the electronic paper display screen 2, an NFC antenna coil 31, an NFC antenna energy harvesting circuit 32, an electronic paper driving circuit 33 and a processor 34 disposed on the circuit board 3, and a switching mechanism 4 disposed on the rear side of the main housing 1 for disconnecting or connecting the NFC antenna coil 31; The NFC antenna energy harvesting circuit 32, the electronic paper driving circuit 33, and the processor 34 are all located around the switching mechanism 4, and the switching mechanism 4 is close to the NFC antenna energy harvesting circuit 32; the NFC antenna coil 31 is connected to the NFC antenna energy harvesting circuit 32, the electronic paper driving circuit 33 and the processor 34 are respectively connected to the NFC antenna energy harvesting circuit 32, the processor 34 is also connected to the electronic paper driving circuit 33, and the electronic paper driving circuit 33 is also connected to the electronic paper display screen 2. The NFC antenna coil 31 is disconnected at the switching mechanism 4 to form a gap segment 51, and the NFC antenna coil 31 is provided with a pair of contact electrodes 52, which are respectively located at both ends of the gap segment 51. The switching mechanism 4 includes: a groove 41 formed on the inner rear wall of the main housing 1, facing the gap 51 of the NFC antenna coil 31 and spanning the gap 51 of the NFC antenna coil 31; a slider 42 formed in the groove 41 and spanning the gap 51 of the NFC antenna coil 31; a conductive sheet 43 formed on the inner side of the slider 42 (the inner side of the slider 42, i.e. the side of the slider 42 facing the circuit board 3) for connecting a pair of contact electrodes 52; a toggle block 44 formed on the outer side of the slider 42 (the outer side of the slider 42, i.e. the side of the slider 42 facing away from the circuit board 3); and a travel hole 45 formed on the outer rear wall of the main housing 1 for the toggle block 44 to pass through and protrude from the outer rear wall of the main housing 1 (the travel hole 45 connects the outer rear wall of the main housing 1 and the groove 41). The slider 42 is a strip-shaped block that extends in the same direction as the groove 41; The travel hole 45 is an elongated hole parallel to the slide groove 41; and the slider 42 spans the travel hole 45; The lever 44 is a strip-shaped block that extends in the same direction as the stroke hole 45, and the outer side of the lever 44 (the outer side of the lever 44, i.e. the side surface of the lever 44 opposite to the slider 42) is provided with anti-slip texture. When the toggle block 44 is at one end of the travel hole 45, the conductive sheet 43 on the inner side of the slider 42 contacts and is electrically connected to a pair of contact electrodes 52 of the NFC antenna coil 31; when the toggle block 44 is at the other end of the travel hole 45, the conductive sheet 43 on the inner side of the slider 42 does not contact the pair of contact electrodes 52 of the NFC antenna coil 31.
