Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1 to 4, an electronic license plate 10 according to the present invention will now be described. An electronic license plate 10 comprises a license plate body 100 and a chip 200. Further, the license plate body 100 includes a plate body 110 and a cover plate 120. The card body 110 includes a housing 111 and a flexible circuit board 112. The flexible circuit board 112 is provided with an antenna electrically connected thereto. Specifically, the antenna is attached to the flexible circuit board 112 through a patch process, that is, the flexible circuit board 112 has the antenna. . The material of the housing 111 is a material that can be injection molded, preferably a non-metallic material, and for example, the material of the housing 111 is a mixture of a PC material and a material such as ABS or ASA. The shell 111 made of the PC material is easy to crack under external force, and the cracking situation can be effectively reduced after the ABS or ASA material is added. The compatibility of ABS and ASA materials and PC materials is very good, and the ABS and ASA materials are more suitable for outdoor products such as license plates.

Further, the housing 111 is provided with a receiving space and a mounting groove 1111 communicating therewith. The flexible circuit board 112 is accommodated in the accommodating space and is integrated with the housing 111 by injection molding. Further, the flexible circuit board 112 has a mounting portion 1121 on which the chip 200 is mounted, and the chip 200 can be mounted on the mounting portion 1121 through the mounting groove 1111.

In the embodiment, the flexible circuit board 112 and the shell 111 are molded into a whole, so that the connection stability of the flexible circuit board 112 and the shell 111 can be ensured, and the generation of cracks is inhibited; meanwhile, the card body 110 is of a structure without the chip 200, and the mounting part 1121 for mounting the chip 200 is only arranged on the flexible circuit board 112, so that the chip 200 is prevented from being detached and welded under the action of high temperature and external force when the flexible circuit board 112 and the shell 111 are subjected to injection molding; moreover, because the card body 110 has a structure without the chip 200, the card body 110 can be compatible with different chips 200 to meet different use scenes.

Further, a plurality of holes are formed in the flexible circuit board 112, and the holes are used for increasing the connection area of the flexible circuit board 112 and the housing 111 after injection molding. The holes may be counter bores distributed on the upper and lower surfaces of the flexible circuit board 112 or through holes penetrating the flexible circuit board 112 in the thickness direction of the flexible circuit board 112. When the flexible circuit board 112 and the housing 111 are injection molded, the melted housing 111 flows into and fills the blind holes/through holes, so as to increase the connection area between the housing 111 and the flexible circuit board 112 after the housing 111 is re-solidified, and increase the connection stability between the flexible circuit board 112 and the housing 111. It is understood that in other embodiments, the through holes are located at the edge of the flexible circuit board 112 to form through slots, so as to improve the connection stability of the flexible circuit board 112 with the housing 111 in the circumferential direction, and in addition, the holes may include a combination of two or three of blind holes, through holes and through slots, and the distribution of the through holes may be set according to the distribution of the electrical components on the flexible circuit board 112.

Since the flexible circuit board 112 is injection molded with the housing 111. The size or area of the flexible circuit board 112 and the antenna can be larger, and the signal is stronger and more stable. The card body 110 of integrated into one piece steadiness is higher, compares with fixed, the sealed trench of modes such as through glue, ultrasonic wave, hot melt adhesive, has improved card body 110 stability. And the injection molding mode is adopted, the flexible circuit board 112 can have a certain displacement space and can be fixed and sealed perfectly in consideration of the characteristics of the flexible circuit board, and the minimum distance between the flexible circuit board 112 or the chip 200 and the surface of the shell 111 is not less than 0.3 mm.

Further, the chip 200 is disposed on the mounting portion 1121 and electrically connected to the flexible circuit board 112 to form an RFID module.
