Abstract

The invention belongs to the technical field of electronic tags and particularly relates to an electronic tag power supply device. The electronic tag power supply device comprises a bottom plate. A cavity is formed in the bottom plate. Two openings are symmetrically formed in the upper end of the bottom plate. The cavity communicates with the openings. A wireless charging plate and a storage battery are arranged in the cavity. The wireless charging plate and the storage battery are fixedly connected with the upper inner side wall and the lower inner side wall of the cavity correspondingly. A charging interface is formed in the bottom end of the bottom plate, and the charging interface, the storage battery and the wireless charging plate are electrically connected. By means of the electronic tag power supply device, wireless charging can be conducted on an electronic tag, the phenomenon that a charging wire is exposed out cannot happen, and due to the fact that redundancy design of a standby storage battery is adopted, after an external power source is powered off, the electronic tag can still be normally used.

Description

Technical field [0001] The invention relates to the technical field of electronic tags, in particular to an electronic tag power supply device. Background technique [0002] Electronic tags are often used in shopping malls, supermarkets, exhibitions and other places where items need to be displayed to indicate basic information such as prices and parameters of items for customers' reference. Compared with paper labels, electronic labels are not easy to damage, have a long service life, and are convenient for information management. [0003] Existing electronic tags mostly use external power supply for direct power supply, and the wires are exposed in the air, which is dangerous. At the same time, if the external power supply fails, the electronic tags will not be able to be used normally, making the use of electronic tags still have certain limitations. Not easy to promote. Summary of the invention [0004] (1) Technical problems to be solved [0005] In order to overcome the short...
