[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 3This utility model provides a technical solution: an embedded access control card reader, including an access control card reader 2 installed at installation position 1. The access control card reader 2 consists of an outer cover 21, a protective sleeve 22, and a module 23. The protective sleeve 22 is embedded inside the outer cover 21, and the module 23 is embedded inside the protective sleeve 22. Multiple bolts pass through the outer cover 21, the protective sleeve 22, and the module 23. A sealing mechanism 5 is provided at the contact point between the access control card reader 2 and the installation position 1. The sealing mechanism 5 consists of a sealing seat 51 and a sealing element 52. The device consists of a protective component 52, which is fitted onto the surface of the protective sleeve 22 and fixed to the sealing seat 51. The designed sealing mechanism 5 improves upon the previous problem where the seams of the embedded access control card reader became channels for dust and moisture to enter the device, especially in outdoor or humid environments. By setting the sealing mechanism 5 at the contact point between the access control card reader 2 and the installation position 1, the sealing mechanism ensures that the access control card reader 2 and the installation position 1 are properly sealed. The gaps between the joints are sealed to improve the sealing level of the device and protect the internal components of the access control card reader 2. The protective component 52 consists of a sealing element 521 and a support plate 522. The sealing seat 51 consists of a base 511 and a sealing gasket 512. The sealing gasket 512 is fixed to the surface of the base 511. The width of the base 511 is the same as the width of the sealing gasket 512. The module 23 is provided with a socket 20 for wiring. The outer cover 21 is provided with a scanning area 3. When a user brings a supported card close to the scanning area 3, the radio frequency signal emitted by the radio frequency module inside the card reader will form an electromagnetic field in this area. The coil inside the card generates an induced current in the electromagnetic field, activating the card chip. The chip encodes and modulates the identity information and transmits it. The card reader antenna receives and processes the signal to identify the user. If the user uses a QR code to open the door, by bringing the mobile phone or paper QR code close to the scanning area 3, the image sensor inside the card reader will collect the QR code image. Then, through the internal image processing and decoding chip, the user's identity information contained in the QR code is restored to complete the identity verification. The outer casing 21 is equipped with a status indicator light 4. The access control card reader 2 has a circuit board inside. The circuit board is the core component of the access control card reader. It integrates many electronic components and circuits and plays a key role in controlling and processing signals. The radio frequency identification circuit works with the sensing area to transmit and receive radio frequency signals to realize communication with the card. The barcode scanning recognition circuit works in conjunction with the image sensor of the scanning area. It controls the image sensor to collect the QR code image, preprocesses the collected image, and then restores the information in the QR code through the decoding algorithm and transmits it to the main control chip for verification. The access control card reader 2 has an antenna inside. The access control card reader 2 has an image sensor inside. The function of the image sensor is to collect the QR code image, convert the light signal into an electrical signal, and then transmit it to the barcode scanning recognition circuit on the circuit board for processing.

[0021] In this embodiment, preferably, the sealing element 521 is fixed to the outer surface of the support plate 522. The bottom edge of the sealing element 521 has an inclined structure. The inclined structure makes it easier to squeeze the sealing element 521 when the sealing mechanism 5 is fitted onto the access control card reader 2, so that the sealing mechanism 5 and the access control card reader 2 are fixed together, and the sealing performance of the sealing mechanism 5 is improved. The height of the sealing element 521 is the same as the height of the support plate 522.

[0022] The working principle and usage process of this utility model are as follows: Based on the installation height, a hole is drilled at installation position 1 according to the engagement dimensions of the access control card reader 2. According to the power requirements of the access control system, a suitable power cord is selected and the wiring is completed. Then, the sealing mechanism 5 is fitted onto the sheath 22 of the access control card reader 2, and the pressure applied to the sealing mechanism 5 causes the recessed area of ​​the sheath 22 to compress the sealing element 521, causing the sealing mechanism 5 to engage with the access control card reader 2. Next, the access control card reader 2 is inserted into the drilled hole, and the included screws are used to lock the access control card reader 2, firmly fixing it to installation position 1. During the screw tightening process, the sealing gasket 512 is pressed, sealing the contact area between the access control card reader 2 and installation position 1. Subsequent debugging operations are performed after the access control card reader 2 is installed.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
