[0045] Please refer to Figure 1 - Figure 6 , an embodiment of the present utility model provides an intelligent cabinet controller 100 with a touch display screen 10 and a face recognition function, which is used for grooved embedded installation. The controller 100 includes: a display screen 10, a middle frame 20 and a rear cover plate 30.

[0046] The surface formed by the display screen 10 is recorded as the first surface S1. The middle frame 20 is fixedly connected to the display screen 10, and the middle frame 20 is integrally formed with a bayonet 21 and a buckle edge 22, and the buckle edge 22 is fixedly connected to the display screen 10. The rear cover plate 30 is fixedly connected to the middle frame 20 and is located on the side of the middle frame 20 away from the display screen 10. Observed in a direction parallel to the first surface S1, the buckle edge 22 is located on the side of the middle frame 20 away from the rear cover plate 30, and a plurality of bayonet 21 are located between the buckle edge 22 and the rear cover plate 30.

[0047] Among them, the buckle edge 22 is a design element used to firmly fix the display screen 10 in the middle frame 20. This design can enhance the connection stability between the display screen 10 and the middle frame 20, and prevent the display screen 10 from shifting or falling off due to vibration or other factors during use. The bayonet 21 is designed to create multiple points of enhanced fixation between the controller 100 and the installed card slot. It allows the controller 100 to be fixed in the card slot by insertion or snapping. The presence of the bayonet 21 makes the assembly process of the components more precise and facilitates the installation of the controller 100 in place. As the main display component of the controller 100, the display screen 10 needs to be stably fixed in the middle frame 20 to ensure its normal operation and avoid damage caused by vibration or external force. The buckle edge 22 provides the necessary fixing force to ensure the stable position of the display screen 10. The middle frame 20 not only supports the display screen 10, but also provides an installation position for the back cover 30. The main function of the back cover 30 is to protect and close the internal components. The bayonet 21 design allows the controller 100 to be firmly fixed in the card slot for installation to prevent the controller 100 from being pried away. The design of the bayonet 21 enhances the stability of the controller 100 after installation, and the design of the buckle edge enables the edge seam of the slot to be covered, which not only improves the aesthetics, but also effectively prevents dust from entering the gap, greatly improving the service life of the controller 100.

[0048] More preferably, the display screen 10 includes: a touch screen panel 11 and a touch screen panel 11 .

[0049] Observed in a direction parallel to the first surface S1, the touch screen panel 11 is located on a side of the middle frame 20 away from the rear cover 30. Observed in a direction perpendicular to the first surface S1, the liquid crystal display screen 12 is fixed to the touch screen panel 11.

[0050] Among them, the touch screen panel 11 is located on the side of the middle frame 20 away from the rear cover plate 30 to ensure the convenience of touch operations. Users can directly operate on the touch screen panel 11, and the touch sensing layer responds more sensitively and accurately to user operations. As the outermost protective layer, the touch screen panel 11 helps protect the liquid crystal display screen 12 from physical impacts, scratches, or dust. The touch screen panel 11 can be replaced, while the liquid crystal display screen 12 is usually more fragile and not easily replaceable. Therefore, the setting of the protective layer is crucial. Fixing the liquid crystal display screen 12 to the touch screen panel 11 can ensure the alignment and stability of the two. This can avoid the deviation or inaccuracy of the displayed content during use. This design enables the touch screen panel 11 and the liquid crystal display screen 12 to be treated as a whole, simplifying the installation and repair processes. If replacement or repair is required, the touch screen panel 11 and the liquid crystal display screen 12 can usually be handled together, reducing the complexity of maintenance. The touch screen panel 11 protects the liquid crystal display screen 12 from damage and also prevents dust and moisture from entering the interior of the display screen 10, enhancing the durability and reliability of the device. Through the design of the touch screen panel 11, users can directly interact with the device, improving the intuitiveness and convenience of operations. If the touch screen panel 11 is damaged, it can be easily replaced, while the liquid crystal display screen 12 remains intact, which reduces the maintenance cost and difficulty.

[0051] Preferably, the display screen 10 further includes: a fill light 13. The fill light 13 is square, and when observed in a direction parallel to the first surface S1, the fill light 13 is located between the touch screen panel 11 and the middle frame 20.

[0052] Among them, the face recognition system relies on good lighting conditions to obtain clear facial images. In the case of insufficient light, the fill light 13 can provide the necessary light source to ensure that the camera can clearly capture the facial features and improve the recognition accuracy. The fill light 13 can provide uniform illumination for the face in various light environments (such as low light environment or backlight environment), reduce shadows and reflections, and enhance the recognizability of facial features. The position of the square fill light 13 between the touch screen panel 11 and the middle frame 20 can more evenly illuminate the entire facial area, ensuring that the face recognition system can obtain a uniform and clear image. Such a position helps to reduce shadows and light spots caused by uneven light. Placing the fill light 13 between the touch screen panel 11 and the middle frame 20 avoids the light directly hitting the user's eyes, which can reduce visual discomfort and keep the user comfortable. This position setting can also reduce the interference of the fill light 13 on the touch screen operation, so that there is a reasonable light source arrangement between the fill light 13 and the touch screen, which will not affect the display and operation of the touch screen. The square fill light 13 can provide a more uniform light source distribution, which is particularly suitable for covering a larger area. Compared with round lamps, square fill lights 13 can better ensure the uniformity of light in facial recognition applications and reduce the situation where local light is too strong or too weak. By integrating the fill light 13 in the display screen 10, a stable light source can be provided under various lighting conditions, significantly improving the performance and reliability of the face recognition system. This is especially important for applications that require accurate recognition in different environments. The setting of the fill light 13 not only improves the effect of the face recognition function, but also maintains the integrity of the device design, ensuring that the device performs more stably and consistently in actual applications.

[0053] More preferably, the controller 100 further includes: a binocular face recognition module 40 , a main control circuit board 50 and an interface circuit board 60 .

[0054] The main control circuit board 50 is fixedly connected to the middle frame 20 and is located on a side of the middle frame 20 away from the display screen 10. Observed along a direction perpendicular to the first surface S1, the interface circuit board 60 is located on a side of the main control circuit board 50 away from the binocular face recognition module 40.

[0055] Among them, the binocular face recognition module 40 is located in front of the display screen 10 and directly faces the user's face. The binocular face recognition module 40 is responsible for capturing the user's facial image and performing face recognition through stereoscopic vision technology. The placement position of this module ensures that it can obtain clear images at the best angle for effective recognition. The main control circuit board 50 is the core component of the entire controller 100, responsible for processing face recognition data, executing control logic, and coordinating the work of other system components. Setting it on the side of the middle frame 20 facing away from the display screen 10 can avoid direct contact with the display screen 10, reduce interference between the display screen 10 and the circuit board, and facilitate the heat dissipation and maintenance of the circuit board. The interface circuit board 60 is usually responsible for connecting external devices and systems, such as communication interfaces, power interfaces, etc. Setting the interface circuit board 60 on the side of the main control circuit board 50 facing away can make the connection between the circuit boards more concise and avoid interference with the main control circuit board 50 due to frequent connection and disconnection. By setting the main control circuit board 50 on the back of the display screen 10 and setting the interface circuit board 60 on the side of the main control circuit board 50 facing away, electromagnetic interference can be effectively reduced. The reasonable layout among the display screen 10, the binocular face recognition module 40, and the circuit board helps to reduce signal interference and improve the stability of the system. The main control circuit board 50 usually generates a lot of heat. Placing it on the side of the middle frame 20 facing away from the display screen 10 helps with heat dissipation and avoids heat accumulation directly near the display screen 10. This can extend the service life of the device and improve performance stability. Separating the interface circuit board 60 and the main control circuit board 50 can simplify the maintenance process. If the circuit board needs to be replaced or upgraded, the relevant components can be accessed and operated more conveniently without affecting the work of other parts. This layout also makes the design of the entire controller 100 more compact and integrated. By reasonably arranging the positions of the internal components, the use of the internal space can be optimized, making the system more integrated and aesthetically pleasing in terms of function.

[0056] Preferably, the controller 100 further includes: a sound cavity 70 and an RFID card reading module 80.

[0057] When observing along the direction perpendicular to the first surface S1, the sound cavity 70 is integrally formed on the middle frame 20. When observing along the direction perpendicular to the first surface S1, the RFID card reading module 80 is located on the side of the interface circuit board 60 facing away from the main control circuit board 50, and the RFID card reading module 80 is fixedly connected to the middle frame 20.

[0058] Among them, the designed position and layout of the sound cavity 70 optimize the sound propagation path. Integrating the sound cavity 70 on the middle frame 20 helps to make the sound more directly transmitted to the user, improving the sound quality and volume. Designing the sound cavity 70 in an integrally formed manner can save space and reduce additional structural components, thus simplifying the overall design. The middle frame 20 itself can play a certain role in vibration isolation, reducing the impact of the vibration generated by the sound cavity 70 on other circuit boards and components. The radio frequency identification card reading module 80 usually needs to maintain a certain distance from the user's card or tag to achieve effective reading. Fixing it at a position on the middle frame 20 can ensure the stability and reliability of its received signal. Setting the radio frequency identification card reading module 80 on the side of the interface circuit board 60 facing away from the main control circuit board 50 helps to reduce the electromagnetic interference generated by the main control circuit board 50 on the card reading module, thereby improving the recognition accuracy and stability of the card reading module. This layout makes the connection between the interface circuit board 60 and the radio frequency identification card reading module 80 more concise, avoiding complex circuit layouts and enhancing the compactness of the overall structure.

[0059] More preferably, the controller 100 further includes: a voice speaker 90. When observed in a direction perpendicular to the first surface S1, the voice speaker 90 is fixed within the sound cavity 70.

[0060] Among them, installing the voice speaker 90 within the sound cavity 70 can utilize the structure of the sound cavity 70 to resonate and amplify the sound, thereby improving the clarity and loudness of the sound. This arrangement can make the audio output more full and powerful. The design of the sound cavity 70 helps to control and reduce sound distortion, making the sound emitted by the voice speaker 90 more pure and accurate, providing a better voice prompt and notification effect. Placing the voice speaker 90 within the sound cavity 70 can more effectively utilize space and reduce the overall volume of the system. This compact design helps to save space while maintaining the functionality and performance of the system. The sound cavity 70 can play a certain shielding role, reducing the electromagnetic interference of the voice speaker 90 from other circuit boards or components during operation. This can ensure the stability and quality of the sound output. The design of the sound cavity 70 can also help to control the sound propagation direction, making the sound better directed towards the user and enhancing the audibility of the voice prompt. This layout reduces the complexity of the internal wiring and improves the overall structure and maintenance convenience of the system.

[0061] More preferably, the middle frame 20 includes: fixing studs 23 and wiring grooves 24.

[0062] When observed in a direction perpendicular to the first surface S1, six of the fixing studs 23 are integrally formed on the edge of the middle frame 20. The wiring groove 24 is integrally formed on the middle frame 20 and is located on the side of the middle frame 20 facing away from the display screen 10. The controller 100 arranges the internal wires through the wiring groove 24.

[0063] Among them, the fixing stud 23 provides a firm mounting point, enabling the internal components to be stably mounted on the middle frame 20, preventing looseness or displacement during use. The wire trough 24 is used to neatly arrange the wires, avoiding chaos of the wires, contributing to the neat arrangement of the wires and preventing wire entanglement. The wire trough 24 makes the inspection and replacement of the wires more convenient, simplifying the maintenance process. The wire trough 24 can protect the wires from physical impact and abrasion, reducing the risk of wire damage or short circuit. The wire trough 24 helps to keep the internal structure of the controller 100 tidy and makes the appearance more beautiful. The fixing stud 23 provides an accurate component mounting position, ensuring the accuracy of assembly.

[0064] Preferably, the rear cover plate 30 includes: fixing holes 31. Six of the fixing holes 31 are integrally formed on the rear cover plate 30, and the radius of the fixing holes 31 is the same as the radius of the fixing stud 23. By abutting the fixing holes 31 against the fixing stud 23 and sequentially passing bolts through the fixing holes 31 and the fixing stud 23, the rear cover plate 30 is fixedly connected to the middle frame 20.

[0065] Among them, the radius of the fixing holes 31 is the same as the radius of the fixing stud 23, ensuring very precise docking between the rear cover plate 30 and the middle frame 20. This design can reduce assembly errors and improve the accuracy of assembly. By passing bolts through the fixing holes 31 and the fixing stud 23, the rear cover plate 30 is firmly fixed on the middle frame 20. This bolt fixing method can provide a strong connection force, ensuring that the rear cover plate 30 will not loosen or fall off during operation. The designed fit ensures that the rear cover plate 30 can be quickly and precisely docked with the middle frame 20, simplifying the assembly process and reducing the difficulty of alignment and fixation. The matching design of the fixing holes 31 and the fixing stud 23 helps to improve the structural stability of the entire controller 100, preventing failures caused by component looseness. The precise fit and firm fixing method make it more convenient and fast for maintenance and replacement of components, reducing the maintenance difficulty. By evenly fixing the rear cover plate 30 on the middle frame 20 with bolts, stress concentration is reduced, thereby reducing the risk of deformation or damage caused by uneven assembly.

[0066] Preferably, the middle frame 20 is made of acrylonitrile-butadiene-styrene and polycarbonate.

[0067] Among them, acrylonitrile-butadiene-styrene is abbreviated as ABS. ABS and polycarbonate have a lower electromagnetic shielding effect compared to metals. This means that RFID signals can more easily penetrate these plastic materials, thereby increasing the card reading distance and signal reception ability of the RFID module. The metal middle frame 20 may cause reflection or interference of RFID signals, resulting in a reduced card reading distance or a decline in signal quality. The shielding effect of metals may affect the accuracy and stability of RFID card reading. As non-metallic materials, ABS and polycarbonate allow RFID signals to be transmitted within the materials without significant attenuation. This enables the RFID card reading module to effectively read tags at a greater distance. The metal middle frame 20 may hinder the transmission of RFID signals, resulting in a limited card reading distance. ABS and polycarbonate materials are easier to process and can be designed with openings or gaps that meet the requirements of RFID card reading, thereby optimizing the layout of the card reading module and signal reception. The metal middle frame 20 may require additional design modifications or special treatment to avoid affecting the propagation of RFID signals. The costs of ABS and polycarbonate are generally lower than those of metals, which not only reduces production costs but also allows for more optimization solutions to be adopted in the design to enhance the performance of RFID card reading. The cost of the metal middle frame 20 is relatively high, and the negative impact it has on RFID signals may require additional design costs to address. ABS and polycarbonate provide sufficient durability without affecting the performance of the RFID module. They also have good corrosion resistance, reducing the impact of environmental factors on RFID performance. Although the metal middle frame 20 has high strength, additional anti-corrosion treatment may be required to maintain RFID performance and the long-term stability of the device.

[0068] Thus, through the design of the controller 100 with the edge of the bayonet 21, after the controller 100 is slotted and embedded, the edge of the bayonet 21 blocks the slotted edge seam, effectively preventing dust from entering; with multiple bayonets 21 located between the snap-in edge 22 and the rear cover plate 30, the controller 100 is firmly fixed in the slot, effectively improving the installation safety of the controller 100.

[0069] The above-described embodiments only represent several embodiments of the present application. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
