[0002] RFID (Radio Frequency Identification) tags are widely used in many fields, such as access control, public transportation, subways, warehousing, logistics, and industrial control. They can achieve automatic identification and have significant advantages in storing product information. Product information can be stored in the tag, and when it enters the magnetic field of the reading device, it emits the product information stored in the chip by using the energy obtained from the induced current. At the same time, with the advancement of Internet of Things (IoT) technology, RFID tags, as an important component, are indispensable for item identification.

[0003] Currently, RFID electronic tag structures on the market have the following problems in actual use: Due to technical reasons, in high-frequency pulse environments such as electrolysis equipment, industrial welding machine operating environments, and electric sparks, they are subject to strong electric and magnetic field interference, which induces high voltage in the coil of the RFID product, easily damaging the RFID chip. Existing RFID electronic tags have poor stability and are easily affected by external interference, causing tag damage and preventing reading devices from reading the tags, reducing ease of use. The usage environment is limited, and the information reading process is easily restricted by its own structure, resulting in a single application scenario. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1 to 4 This utility model embodiment provides an anti-interference RFID electronic tag structure device. This embodiment improves the structure of the RFID electronic tag to give it the advantage of stable anti-interference. Specifically, taking the RFID electronic tag structure as an example, as a preferred solution in this embodiment, the RFID electronic tag structure is specifically an anti-interference RFID electronic tag structure device, which can stably prevent interference during the use of the RFID electronic tag.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution: an anti-interference RFID electronic tag structure device, which is mainly used in electronic tag scenarios.

[0026] The mounting component 1 has an internal movable component 2, the movable component 2 has a fixed component 3 on its side, the fixed component 3 has a main component 4 on its side, and the main component 4 has an auxiliary component 5 on its side.

[0027] In the above embodiments, as a preferred option, the mounting component 1 includes a label housing 101, and a microwave absorbing material layer 102 is fixedly installed at both ends of the label housing 101. By setting the microwave absorbing material layer 102 at both ends of the label housing 101 and using a material with high microwave absorption performance, the incident electromagnetic waves can be converted into heat energy and consumed, thereby reducing the interference of reflected and scattered electromagnetic waves on the label.

[0028] In the above embodiment, as a preferred solution, the movable component 2 includes a movable rod 201. The movable rod 201 is slidably connected to the top of the label housing 101. One end of the movable rod 201 is fixedly connected to a movable piece 202, and the other end of the movable rod 201 is fixedly connected to a first inclined block 203. A second inclined block 204 is slidably engaged on one side of the first inclined block 203, and a limiting groove 205 is formed on the other side of the first inclined block 203. The movable piece 202 is contacted by an external identification device to move the movable piece 202 and push the movable rod 201 to move, thereby causing the movable rod 201 to drive the first inclined block 203 to move. At this time, the inclined surface of the first inclined block 203 pushes the second inclined block 204 to move laterally.

[0029] In the above embodiments, as a preferred option, the fixing component 3 may include a fixing rod 301 and a fixing plate 302. The side of the fixing rod 301 is slidably connected to the inside of the limiting groove 205, and both ends of the fixing rod 301 are fixedly connected to the inside of the label housing 101. One side of the fixing plate 302 is fixedly installed to the side of the second inclined block 204. The fixing component 3 also includes a sliding rod 303 and a spring 304. One end of the sliding rod 303 is fixedly connected to the side of the fixing plate 302, and the surface of the sliding rod 303 is sleeved with... The side of the spring 304 and the slide bar 303 are slidably connected to the inside of the label housing 101. When the first inclined block 203 moves, it can cooperate with the limiting groove 205 on the side of the first inclined block 203 to limit the movement along the direction of the fixed rod 301. At the same time, the second inclined block 204 drives the fixed plate 302 to limit the movement. When the second inclined block 204 moves in cooperation with the fixed plate 302, the slide bar 303 and the fixed plate 302 move at the same time and compress the spring 304, so that the spring 304 drives the slide bar 303 to play a reset role.

[0030] In the above embodiments, as a preferred option, the main component 4 includes a chip 401. The other side of the fixing plate 302 is fixedly installed on the side of the chip 401. One end of the chip 401 is fixedly installed with a terminal 402. With the RFID chip 401 having high sensitivity and anti-interference capabilities, it can work stably in complex electromagnetic environments. The chip 401 integrates advanced signal processing algorithms, which can filter and correct received signals to improve signal accuracy. The terminal 402 adopts a low-loss connection method to ensure efficient signal transmission and output at the working frequency band.

[0031] In the above embodiments, as a preferred option, the auxiliary component 5 includes a shielding plate 501 and a conductive layer 503. The shielding plate 501 has an inner groove 502 inside, and the inside of the inner groove 502 slides with the side of the end position 402. The side of the conductive layer 503 is fixedly installed inside the tag housing 101. When the fixing plate 302 moves, the end position 402 of the chip 401 on the side of the fixing plate 302 can extend outward for transmission or retract inward for blocking within the inner groove 502 inside the shielding plate 501. When the electronic tag is in use, the end position 402 of the chip 401 transmits signals stably. When not in use, it is blocked and sealed. When multiple sets of electronic tags are used at the same time, it prevents electromagnetic signal leakage interference and has a certain anti-interference capability. It can further improve the stability and reliability of the tag and is suitable for various complex electromagnetic environments and application scenarios that are easily interfered with. It effectively improves the reading accuracy and reliability of RFID electronic tags and reduces the occurrence of misreading and missed reading.

[0032] All electrical components mentioned in this article are electrically connected to an external main controller, which can be a conventional known device such as a computer for control.

[0033] In this invention, the working steps of the device are as follows:

[0034] 1. When external electromagnetic interference signals reach the anti-interference RFID electronic tag structure device, the electromagnetic signals first enter the absorbing material layer 102, are absorbed by the absorbing material and converted into heat energy, and the shielding layer blocks most of the electromagnetic signals and reflects them back, thereby ensuring that the tag body can work normally.

[0035] 2. When the external identification device contacts the movable piece 202, the movable piece 202 moves and pushes the movable rod 201 to move, thereby causing the movable rod 201 to drive the first inclined block 203 to move. At this time, the inclined surface of the first inclined block 203 pushes the second inclined block 204 to move laterally. When the first inclined block 203 moves, it can cooperate with the side limiting groove 205 of the first inclined block 203 to move in a limited direction along the fixed rod 301. At the same time, the second inclined block 204 drives the fixed plate 302 to move in a limited direction.

[0036] 3. The RFID chip 401 has high sensitivity and anti-interference capabilities. The chip 401 integrates advanced signal processing algorithms, which can filter and correct received signals. It works with the terminal 402 in a low-loss connection mode to output the operating frequency band. When the fixing plate 302 moves, the terminal 402 of the chip 401 on the side of the fixing plate 302 can extend outward for transmission or retract inward for blocking within the inner groove 502 inside the shielding plate 501. When the electronic tag is in use, the terminal 402 of the chip 401 transmits signals stably. When not in use, it is blocked and sealed. When multiple sets of electronic tags are used at the same time, it prevents electromagnetic signal leakage interference and has a certain anti-interference capability.
