Embodiment 1

[0038] like figure 2 as shown, figure 2 The card body 1 in comprises a through hole 11, and a film 12 is pasted on the card body 1; as image 3 as shown, image 3 The electronic tag 2 in includes an insulating substrate 21 and an attached sheet 24 .

[0039] like image 3 , Figure 4 As shown, the electronic tag 2 includes a radio frequency identification chip 23 and a slot antenna 22 electrically connected to the radio frequency identification chip 23 . The electronic label 2 also includes an attached sheet 24, which is pasted on the surface of the slot antenna 22, and the side close to the slot antenna 22 is provided with a groove corresponding to the size and position of the radio frequency identification chip 23 (not shown in the figure), and the radio frequency identification chip 23 Embedded in the groove, the radio frequency identification chip 23 is connected to the slot antenna 22 in a binding manner, effectively reducing the overall thickness of the electronic...

Embodiment 2

[0047] like Figure 5 As shown, the technical solution of embodiment 2 is mostly the same as the technical solution of embodiment 1, and its distinguishing technical feature is that a first adhesive layer 25 is provided between the attachment piece 24 and the slot antenna 22, and the first adhesive layer 25 The size is the same as that of the insulating substrate 21, the slot antenna 22 is electrically connected or capacitively coupled to the card body 1 through the edge of the through hole 11, and the side of the attached sheet 24 facing the card body 1 is provided with a third adhesive layer 27, which is insulated A fourth adhesive layer 28 for bonding the vehicle body is provided on the side of the substrate 21 opposite to the slot antenna 22 . The first adhesive layer 25 , the third adhesive layer 27 and the fourth adhesive layer 28 are all double-sided adhesives, and the first adhesive layer 25 and the third adhesive layer 27 are all curable adhesives. The slot antenna 2...

Embodiment 3

[0051] like Figure 6 As shown, the technical solution of embodiment 3 is mostly the same as the technical solution of embodiment 2, and its different technical feature is that a second adhesive layer 26 is provided between the slot antenna 22 and the insulating substrate 21, and the second adhesive layer 26 And the adhesive strength of the first adhesive layer 25 to the slot antenna 22 is greater than the breaking strength of the material of the slot antenna 22 , and the adhesive strength of the second adhesive layer 26 is lower than the adhesive strength of the fourth adhesive layer 28 .

[0052] There are more than two hollowed out parts 261 inside the second adhesive layer 26, and the hollowed out parts 261 can be characters or patterns, which looks more beautiful. Once someone removes the license plate with violence, the hollow part 261 will be broken, the slot antenna 22 will be destroyed, and the license plate of the present invention will be damaged and will not be reu...

Abstract

The invention provides an electronic license plate which comprises a plate body and an electronic tag. The electronic tag comprises an insulation substrate, a slot antenna and a radio frequency identification chip, wherein the slot antenna and the radio frequency identification chip are attached to the insulation substrate and are electrically connected with each other. The electronic tag further comprises an attachment piece attached to the slot antenna. The plate body is provided with a through hole corresponding to the attachment piece in size and shape, and the attachment piece is embedded in the through hole. The electronic license plate has the advantages that the tag and the license plate are processed respectively and then assembled and installed and the processing is easy; producers can effectively control production cost and effectively improve production efficiency; an original antenna on the plate body is replaced by the special slot antenna, the communication quality is further improved, and the induction scope is enlarged.

Description

technical field [0001] The invention relates to a license plate, in particular to an electronic license plate. Background technique [0002] In the process of intelligentization of the transportation system, vehicle identification is an important technical improvement. The emergence of intelligent electronic license plates is conducive to daily traffic vehicle management and effectively prevents problems such as management confusion caused by fake license plates to traffic management departments. Most of the electronic license plates in the prior art use radio frequency identification technology, and the radio frequency identification system generally includes three parts: a label, a reader and an antenna. The existing electronic license plate generally installs an electronic tag made of a radio frequency identification chip in the license plate, and uses the metal plate body of the license plate as part or all of the antenna, which can cooperate with the corresponding reade...
