[0023] 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.

[0024] Please see Figures 1-4 This utility model provides a technical solution: a display module for intelligent access control, including a protective mounting frame 1, an access control housing 2 movably mounted inside the protective mounting frame 1, an access control top cover 3 movably mounted on the side of the access control housing 2 away from the protective mounting frame 1, a display screen body 4 fixedly mounted in the middle of the access control top cover 3, and connection and disassembly mechanisms 5 provided on both sides of the access control housing 2.

[0025] The connecting and disassembling mechanism 5 includes mounting blocks 501. Several mounting blocks 501 are evenly fixedly installed on both sides of the access control housing 2. Movable connecting rods 502 are fixedly installed on the two sides of the mounting blocks 501 that are far apart. Positioning sleeves 503 are sleeved on the outer ends of the movable connecting rods 502. Supporting springs 504 are fixedly installed in the middle of the mounting blocks 501 and the positioning sleeves 503. Several positioning holes 505 are evenly added to both sides of the protective mounting frame 1. The positioning sleeves 503 are movably connected inside the positioning holes 505. When pressed, the supporting springs 504 are squeezed. The supporting springs 504 drive the positioning sleeves 503 to retract and slide outside the movable connecting rods 502. Under the guidance of the movable connecting rods 502, the positioning sleeves 503 are smoothly inserted into the positioning holes 505.

[0026] A plurality of fixing holes 6 are evenly distributed on the inner wall of one side of the protective mounting frame 1. A first magnetic block 7 is fixedly installed on the inner wall of one side of the protective mounting frame 1. A second magnetic block 8 is fixedly installed on the side of the access control housing 2 away from the access control top cover 3. The second magnetic block 8 is magnetically connected to the first magnetic block 7. A control component 9 is fixedly installed on the inner wall of the bottom end of the access control housing 2. The control component 9 is electrically connected to the display screen body 4. A backlight module 10 is installed on the inner wall of the top end of the access control housing 2. The backlight module 10 is electrically connected to the control component 9. A plurality of connecting through holes 11 are evenly distributed on one side of the access control top cover 3. A plurality of connecting through holes 11 are evenly distributed on one side of the access control housing 2. The screw hole 12 and the connecting through hole 11 correspond to the connecting screw hole 12. A connecting bolt 13 is movably installed on one side of the access control cover 3. The connecting bolt 13 passes through the connecting through hole 11 and is threadedly connected to the connecting screw hole 12. The protective mounting frame 1 has first heat dissipation mesh holes 14 on both sides, and the access control housing 2 has second heat dissipation mesh holes 15 on both sides. The second heat dissipation mesh holes 15 correspond to the first heat dissipation mesh holes 14. The corresponding first heat dissipation mesh holes 14 and second heat dissipation mesh holes 15 on the protective mounting frame 1 and the access control housing 2 form a heat dissipation channel. During the operation of the display module, the heat generated by the control component 9, backlight module 10 and other components is dissipated to the external environment through these heat dissipation mesh holes.

[0027] Working principle: When installing the display module, first fix the protective mounting frame 1 to the target position, such as the access control equipment installation location, through the fixing mounting hole 6. Then, press the positioning sleeves 503 on both sides of the access control housing 2 to simultaneously place the access control housing 2 into the protective mounting frame 1. When pressed, the support spring 504 is compressed, and the support spring 504 drives the positioning sleeve 503 to retract and slide outside the movable connecting rod 502. Under the guidance of the movable connecting rod 502, the positioning sleeve 503 smoothly inserts into the positioning hole 505. At the same time, as the access control housing 2 approaches, the second magnetic block 8 on the access control housing 2 attracts the first magnetic block 7 on the inner wall of the protective mounting frame 1, and the access control housing 2 moves closer to the target location. The access control housing 2 is securely fixed inside the protective mounting frame 1 in one step, completing the quick installation of the access control housing 2 and the protective mounting frame 1. For disassembly, simply press the positioning sleeve 503 again and then pull the access control housing 2 outwards. During daily use, the protective mounting frame 1 plays a primary protective role. When external forces such as collisions or compressions act on the display module, the protective mounting frame 1 is the first to withstand the impact. Its high-strength structure effectively disperses and buffers external forces, preventing them from directly acting on the access control housing 2 and the display body 4, thus protecting the internal core components from damage. When the intelligent access control system is running, the main control device of the access control system communicates with the control unit via the communication module. Component 9 sends various access control information, such as visitor images, door opening records, and operation prompts. The microprocessor in component 9 receives the data, processes and analyzes it, and then transmits the processed signal to the display screen 4 and the backlight module 10. The display screen 4, acting as the display terminal, uses its high-definition LCD screen to clearly and accurately display the access control information based on the received signal. Simultaneously, the backlight module 10 operates under the control of component 9. If the ambient light sensor detects weak ambient light, component 9 controls the LED backlight in the backlight module 10 to increase brightness; if the ambient light is strong, it reduces the LED backlight brightness. The brightness is automatically adjusted according to the ambient light to ensure that users can clearly view the information on the display screen 4 under various lighting conditions. The first heat dissipation mesh 14 and the second heat dissipation mesh 15 on the protective mounting frame 1 and the access control housing 2 form a heat dissipation channel. During the operation of the display module, the heat generated by the control component 9, the backlight module 10 and other components is dissipated to the external environment through these heat dissipation meshes, ensuring that the internal electronic components work at a suitable temperature and avoiding the impact of overheating on the performance and lifespan of the display module, thus indirectly improving the protection performance. Connection holes are opened on the inner wall of the protective mounting frame 1 and the back of the access control housing 2, so that wiring can be connected according to the installation.

[0028] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
