[0027] Example

[0028] A door access card with RFID includes a panel 1, a mounting groove 2 is provided on the surface of the panel 1, an adapted sensing part 5 is installed in the mounting groove 2, a plurality of adhesive pads 3 are distributed on the bottom surface of the mounting groove 2, the bottom surface of the sensing part 5 is bonded to the adhesive pad 3, a strip groove 4 is provided on the side surface of the mounting groove 2, a tear strip 6 for separating the sensing part 5 from the adhesive pad 3 is connected to the side surface of the sensing part 5, the tear strip 6 is located in the strip groove 4, an elastic body 7 is provided at the free end of the tear strip 6, and the elastic body 7 is bent in the strip groove 4, and a protective layer 13 is provided on the surface of the panel 1 to seal the sensing part 5 and the tear strip 6 inside.

[0029] In this embodiment, Figure 3 As shown, the protective layer 13 covers the surface of the panel 1, which is used to seal the internal components such as the sensing part 5 and the tear strip 6 inside to protect them from erosion and damage from the external environment. The protective layer 13 should also have good wear resistance and scratch resistance to ensure the long-term use effect of the access card; the panel 1 is the main bearing structure of the access card, which provides support and protection for other components. The mounting groove 2 is opened on the surface of the panel 1 for installing the RFID sensing part 5, so that the sensing part 5 can be firmly fixed on the access card, while avoiding the possible damage caused by direct exposure of the sensing part 5 to the external environment. The sensing part 5 contains an RFID chip for storing and transmitting access control information. The sensing part 5 communicates wirelessly with the card reader of the access control system through a specific frequency to realize the opening function of the access control, such as Figure 2As shown, the adhesive pad 3 is distributed on the bottom surface of the mounting groove 2 as a plurality of small pads, which are used to firmly adhere the sensing part 5 to the panel 1, which not only improves the stability of the sensing part 5, but also facilitates subsequent replacement and maintenance. The tear strip 6 is connected to the side of the sensing part 5, which is used to conveniently separate the sensing part 5 from the adhesive pad 3 when the sensing part 5 needs to be replaced or repaired. The strip groove 4 is arranged on the side of the mounting groove 2 to accommodate the tear strip 6. The elastic body 7 is arranged at the free end of the tear strip 6. When encapsulating, the elastic body 7 is bent in the strip groove 4 and then pressed by the protective layer 13. Figure 6 As shown, after the protective layer 13 is removed, the bent portion of the elastic body 7 (rubber material) will automatically pop out, so that it is convenient for maintenance personnel to pinch the elastic body 7 and drive the tear strip 6 to take the sensing part 5 out of the installation slot 2, and the visual sensing part 5 and the panel 1 are conveniently separated, so as to facilitate the replacement of a new sensing part 5. This solution can facilitate the disassembly of the sensing part 5 and the access card. When the sensing part 5 or the access card is damaged, any one of them can be replaced separately, which reduces the replacement cost.

[0030] Furthermore, the protective layer 13 is a hard board, a circle of sealing gasket is provided between the protective layer 13 and the panel 1 , and the four corners of the protective layer 13 are connected to the panel 1 via screws 14 .

[0031] Specifically, the sealing gasket between the protective layer 13 and the panel 1 further improves the waterproof and dustproof performance of the access card. The sealing gasket is usually made of elastic material, such as silicone or rubber, which can fit tightly between the panel 1 and the protective layer 13 to form an effective barrier to prevent external impurities such as moisture and dust from invading the interior of the access card and protect core components such as the RFID sensor 5 from damage.

[0032] In addition, if Figure 3 As shown, the four corners of the protective layer 13 are connected to the panel 1 by screws 14, which ensures the stability of the protective layer 13. The screw 14 connection is not only high in strength, but can also be adjusted as needed to ensure a close fit between the protective layer 13 and the panel 1. This connection method is also convenient for subsequent disassembly and maintenance work.

[0033] Furthermore, there are a plurality of adhesive pads 3 , which are distributed on the bottom surface of the mounting groove 2 in a matrix manner.

[0034] Specifically, Figure 2 As shown, the multiple adhesive pads 3 can more evenly disperse the weight and force of the sensing part 5, thereby increasing the contact area and adhesion between the sensing part 5 and the panel 1, so that the sensing part 5 is more firmly fixed in the mounting groove 2. Even when subjected to external impact or vibration, the sensing part 5 is not easy to fall off or shift.

[0035] Furthermore, a decorative layer 12 is provided on the top surface of the protective layer 13 and the bottom surface of the panel 1. Specifically, the decorative layer 12 can be patterned to enhance the aesthetics of the access card.

[0036] Furthermore, a shielding ring 17 is provided on the side wall of the mounting groove 2. Specifically, Figure 2 As shown, the shielding ring 17 can provide a shielding effect for the electromagnetic interference signal on the outside of the internal RFID chip, ensuring that the RFID chip can be used in a safe and stable environment.

[0037] Furthermore, the sensing unit 5 includes a carrier 18, and an active transponder 8 is provided inside the carrier 18 for sending location information to a reader via a wireless network. The reader is an access control device, and the access control device is used to identify an access control card according to identification information.

[0038] Furthermore, the active transponder 8 includes a radio frequency identification RFID chip 10 , an active antenna 9 , and a battery 11 . The radio frequency identification RFID chip 10 is connected to the active antenna 9 , and the battery 11 provides power for the active transponder 8 .

[0039] Specifically, Figure 4 As shown, the carrier 18 can be circular or rectangular, and an active transponder 8 is arranged inside the carrier 18. The active transponder 8 is used to send identification information to the reader through a wireless network. The location information and identification information are generated by the wireless radio frequency identification RFID chip 10 in the active transponder 8. The reader identifies the corresponding carrier 18 according to the identification information. The reader is generally an access control device, and the access control device identifies the access control card according to the identification information.

[0040] Further, such as Figure 5 As shown, the top surface of the carrier 18 is provided with an installation cavity 15 for installing the battery 11 , and the bottom surface of the installation cavity 15 is a flexible rubber pad 16 , and the battery 11 can be taken out of the installation cavity 15 by pressing the rubber pad.

[0041] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form.
