Description

Technical Field

[0001] The utility model belongs to the technical field of electronic tags, and in particular relates to an implantable tire tag. Background Art

[0002] Radio Frequency Identification (RFID) is a contactless identification system that uses radio frequency to transmit and process information about items by attaching small chips to various items. It typically consists of an RFID tag for detecting item information and a reader for reading the information stored on the RFID tag. The RFID tag consists of a chip and an antenna connected to the chip. When used, the RFID tag is attached to or inserted into an item to detect the item's real-time information.

[0003] With the development of the information age, the application of radio frequency identification (RFID) systems to tires has become a development trend in tires today. In this way, various tire data can be obtained at any time. Currently, there are many types of RFID-based tire tags on the market. Some are based on PCBs and have small springs welded at both ends as tag antennas, which are implanted in the tire before vulcanization; some are made into rubber sheets and pasted on the finished tire. However, the above methods all have certain limitations. The main reason is that the antenna and chip are usually welded together. When the tire is in motion, it is easy to cause the weld to break, making the RFID chip ineffective. Therefore, a new type of tire tag is needed. The present utility model solves this technical problem. Utility Model Content

[0004] The utility model provides an implantable tire tag, which only requires connecting the RFID module to a metal wire and then directly implanting it into the tire and vulcanizing it, so that it becomes one with the tire. It has a simple structure and does not require welding work, thereby improving production efficiency and being more suitable for the tire's usage environment.

[0005] An implantable tire tag includes an RFID module, a metal wire connected to the RFID module, and a covering layer connected to the RFID module and the metal wire. The RFID module and the metal wire form electromagnetic field coupling to transmit signals.

[0006] Furthermore, the RFID module includes a PCB substrate and an RFID chip attached to the PCB substrate, and the PCB substrate and the RFID chip form an infield antenna.

[0007] Furthermore, an etched antenna is provided on the PCB substrate.

[0008] Furthermore, the coating layer includes black glue, and the black glue is used to coat and protect the RFID module and the metal wire by glue dripping.

[0009] Furthermore, the RFID module is connected to a coupling region in the middle of the metal wire through the coating layer.

[0010] The technical effects of the utility model are as follows:

[0011] (1) The RFID module in this solution can be used as an inner field antenna. It is bonded to the metal wire through the coating layer. The RFID module as the inner field antenna will form an electromagnetic field coupling with the metal wire to transmit signals, thereby eliminating the need for welding to connect, improving production efficiency, and being more suitable for the use environment of the tire, avoiding the situation where the weld point breaks during the movement of the tire;

[0012] (2) The RFID chip and PCB substrate in this solution are covered with black glue. The black glue not only connects the various components, but also protects them. Fixing them by dripping glue is more convenient and will not cause the solder joints to break, thus ensuring that the device can work normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments and drawings.

[0017] See also Figure 1 、 Figure 2 An implantable tire tag includes an RFID module, a metal wire 1 connected to the RFID module, and a covering layer 2 connected to the RFID module and the metal wire 1. The RFID module and the metal wire 1 form an electromagnetic field coupling to transmit signals.

[0018] Based on the actual usage scenario, the staff can adjust the length of the metal wire 1 and the coupling parameters of the RFID module to achieve perfect impedance matching and signal coupling. The material of the metal wire 1 can be selected according to specific needs and usage scenarios. During tire production, this device can be directly implanted and vulcanized into the tire, becoming an integral part of the tire.

[0019] Furthermore, the RFID module includes a PCB substrate 3 and an RFID chip 4 bonded to the PCB substrate 3. The PCB substrate 3 and the RFID chip 4 form an internal field antenna. During production, depending on the actual situation, after bonding the RFID chip 4 to the PCB substrate 3, a glue application process can be performed first. The black glue protects the RFID chip 4 and prevents damage during processing. Then, in a subsequent process, the RFID module is bonded to the metal wire 1 via the coating layer 2, thereby completing production through two glue application processes.

[0020] Furthermore, an etched antenna is provided on the PCB substrate 3 .

[0021] Furthermore, the coating layer 2 includes black glue, which is used to coat and protect the RFID module and metal wire 1 through a glue-drip method. Compared with welding, the glue-drip method adopted in this solution is suitable for large-scale assembly line production, greatly improving production efficiency. Moreover, different RFID modules (infield antennas) can be designed and combined with metal wire 1 of different specifications to meet different usage scenarios.

[0022] Furthermore, the RFID module is connected to the coupling area in the middle of the metal wire 1 through the coating layer 2. There is no wire connection between the RFID module and the metal wire 1, and they work only by coupling of the electric field. Physically, the two are bonded by black glue to ensure a suitable distance and ensure the reliability of signal coupling. Figure 1 The dotted parts in the picture are all black vinyl.

[0023] The principle of this utility model is as follows:

[0024] First, the packaged RFID chip 4 is attached to the PCB substrate 3 to form an RFID module, which is used as an inner field antenna, and the RFID chip 4 is protected by black glue. Then, the entire RFID module is bonded to the metal wire 1 with black glue, and the RFID module is covered to protect it. There is no metal wire connection between the RFID module and the metal wire 1. The inner field antenna and the metal wire 1 form an electromagnetic field coupling to transmit signals. Compared with the welding method in the prior art, the tire tag processed by the above method is simpler in process. Each tag only needs to use a fixed length of metal wire 1, and the RFID module is coupled in a fixed position. It can be cut and placed on an assembly line, and then fixed by glue dripping. Compared with other tire tags that require sewing or welding, production efficiency is improved and costs are saved.

[0025] The above embodiments are only preferred embodiments of the present invention. Those skilled in the art can derive other embodiments from the above embodiments without creative work. Therefore, this application protects not only the above embodiments, but also the scope consistent with the principles and features of this application.
