[0001] This utility model relates to the field of intelligent access control technology, specifically to an intelligent access control intercom device. Background Technology

[0002] With the development of intelligent technology, intelligent access control intercom devices are increasingly widely used in modern buildings. These devices not only enable voice and video communication between visitors and residents, but also have functions such as identity recognition and remote control, making them an important facility for ensuring the safety of homes and public areas.

[0003] Currently, smart door access control intercom devices on the market typically require drilling and screw fixing to install the device itself in a recess in the wall or door frame. This traditional installation method has obvious drawbacks: Firstly, the installation process requires specialized tools, is cumbersome and time-consuming, and demands a high level of technical skill from the installers. Secondly, drilling can cause permanent damage to the wall, affecting the building's aesthetics. Furthermore, when the device needs repair or replacement, the disassembly process is equally complex and can easily further damage the structure of the installation location. In addition, the existing devices' display screen protection structure mostly uses screws to fix the transparent plate, which is not only inconvenient to install and remove, but also prone to problems such as loose screws and transparent plates falling off after long-term use, affecting the device's protective effect and service life.

[0004] Therefore, there is an urgent need for an intelligent door access control intercom device that can solve the above problems and achieve convenient installation and disassembly. The intelligent door access control intercom device provided by this utility model effectively solves the shortcomings of the existing technology through innovative mechanical structure design and functional module layout, and has important practical application value.

[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. 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 5 This utility model embodiment provides an intercom device for installation scenarios that avoid permanent damage to walls. This embodiment improves the structure of the intercom device to enable rapid installation and disassembly. Specifically, taking rapid installation and fixing within a groove as an example, as a preferred solution in this embodiment, the intercom device is a smart door disabling intercom device, which can be quickly installed and disassembled without the need for other tools.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: an intelligent door access control intercom device, which is mainly used in installation scenarios that avoid permanent damage to the wall surface.

[0026] The device includes a protective shell 1. Guide grooves 2 are provided on both sides of the outer surface of the protective shell 1. Two adjusting seats 3 are slidably connected to the middle of the inner sidewall of the guide groove 2. Push rods 4 are rotatably connected to both sides of the outer surface of the two adjusting seats 3 via a rotating shaft. Pressure blocks 5 are connected to the ends of the push rods 4 via a rotating shaft. Threaded rods 6 are rotatably inserted into both sides of the outer surface of the protective shell 1. The outer surface of the threaded rods 6 is threadedly connected to the outer surface of the two adjusting seats 3.

[0027] In this embodiment, the protective shell 1 provides a physical mounting carrier for electronic components such as the display screen 7, camera 12, and sensor 14, forming an integrated structure. It serves as the mounting base for the guide groove 2, threaded rod 6, etc., ensuring the relative positional accuracy of each component. The shell material provides basic protection against external impacts, dust, and minor water splashes, improving the durability of the equipment. The guide groove 2, a long, narrow groove extending longitudinally along the protective shell 1, provides a linear sliding guide for the adjustment seat 3, limiting its movement trajectory to the vertical direction to ensure stable adjustment without deviation. It cooperates with components such as the threaded rod 6, adjustment seat 3, and push rod 4 to form the motion reference of the linkage mechanism, ensuring the uniform transmission of the installation clamping force. The adjustment seat 3, a block-shaped component that slides with the guide groove 2, has a threaded hole for the threaded rod 6 and a shaft connection hole for the push rod 4 on its outer surface, serving as the actuator for driving the threaded rod 6. It converts the rotational motion of the threaded rod 6 into rotational motion through threaded transmission. The linear motion is achieved by the two adjusting seats 3 being linked to the pressure block 5 via the push rod 4, thus enabling precise control of the extension position of the pressure block 5. The two ends of the push rod 4 are connected to the connecting rod components of the adjusting seat 3 and the pressure block 5 via rotating shafts, serving as a force transmission medium to convert the linear motion of the adjusting seat 3 into the extension / retraction motion of the pressure block 5. The block-shaped component connected to the end of the pressure block 5 and the push rod 4 can extend from the upper and lower sides of the protective shell 1 and directly contact the inner wall of the mounting groove, providing a stable clamping force by increasing the contact area. The position can be adjusted in conjunction with the adjusting seat 3 to adapt to mounting grooves of different depths, improving the equipment's installation versatility. The threaded rod 6 serves as a power input component, driving the adjusting seat 3 by manual or tool rotation. The positive and negative thread design ensures that the two adjusting seats 3 move synchronously in opposite directions or away from each other when the threaded rod 6 rotates, ensuring that the pressure block 5 extends / retracts symmetrically, avoiding unilateral force that could cause the equipment to tilt, and improving installation stability.

[0028] In the above embodiments, as a preferred solution, a display screen 7 is fixedly installed on one side of the outer surface of the protective shell 1, and a transparent plate 10 is detachably installed on the outer surface of the protective shell 1 outside the display screen 7. The human-computer interaction interface fixedly installed on one side of the protective shell 1 through the display screen 7 displays visitor video images, operation menus, equipment status and other information, realizing visual interaction. In conjunction with the camera 12 and intercom function, it supports real-time video calls between residents and visitors, improving access control security.

[0029] In the above embodiments, as a preferred solution, magnets 8 are fixedly installed on the outer surface of the protective shell 1 at the four corners of the display screen 7, and a protective frame 9 is fixedly connected to the outer surface of the transparent plate 10. One side of the protective frame 9 is attracted to the outer surface of the magnet 8. The transparent plate 10 covers the outer side of the display screen 7, and the protective frame 9 is provided at the edge. The protective frame 9 is attracted and fixed to the magnets 8 at the four corners of the protective shell 1. The transparent plate 10 protects the display screen 7 from external damage such as dust, rain, and scratches, without affecting the display effect. The magnetic attraction connection of the magnet 8 replaces the traditional screw fixation, realizing the quick disassembly and assembly of the transparent plate 10, which is convenient for cleaning or replacement. The protective frame 9 enhances the edge strength of the transparent plate 10, avoids edge breakage due to collision, and improves the overall protection performance.

[0030] In the above embodiment, as a preferred solution, partitions 11 are fixedly connected to both sides of the outer surface of the protective shell 1 on the outside of the guide groove 2. The partitions 11 are fixed to the long strip-shaped baffles on both sides of the protective shell 1 and the periphery of the guide groove 2 to prevent external debris from entering the guide groove 2, avoid blocking the sliding track of the adjustment seat 3, and form a physical isolation of the movement area of ​​the push rod 4 to prevent external force from accidentally touching the push rod 4 and causing the adjustment mechanism to fail.

[0031] In the above embodiment, as a preferred solution, a camera 12 is fixedly installed in the middle of the upper part of the outer wall of the protective shell 1, and supplementary lights 13 are fixedly installed on both sides of the outer wall of the protective shell 1 on the camera 12. The camera 12 collects visitor images or videos in real time as visual input for identity recognition and video calls. The middle installation position takes into account the field of view, avoids obstruction, and ensures complete capture of visitor facial features. The supplementary lights 13 automatically supplement light in low light environment, improve the clarity of the camera 12, and avoid images that are too dark or blurry. The symmetrical layout ensures that the light evenly covers the visitor's face, reduces shadow interference, and improves the accuracy of face recognition.

[0032] In the above embodiments, as a preferred solution, a sensor 14 is fixedly installed on the lower part of the outer surface of the protective shell 1, and a speaker 15 is fixedly installed on the bottom of the protective shell 1. The sensor 14 detects the approach of a visitor and automatically wakes up the device, reducing standby power consumption. In conjunction with the speaker 15 and microphone, passive sensing triggering of calls is realized, improving the convenience of user interaction.

[0033] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0034] In this invention, the working steps of the device are as follows:

[0035] First, locate the groove. Determine a suitable installation position on the wall or door frame and create a matching groove. Ensure that the depth and width of the groove meet the equipment installation requirements. Use tools to rotate the threaded rods 6 on both sides of the protective shell 1. Use the positive and negative threads to drive the relative movement of the adjusting seats 3 on both sides. Push the pressure block 5 through the push rod 4 so that the pressure block 5 extends from the upper and lower sides of the protective shell 1 and is adjusted to a position suitable for the groove size.

[0036] Next, embed the entire device into the groove, and fine-tune the threaded rod 6 again to make the pressure block 5 fit tightly against the inner wall of the groove. Use clamping force to fix the device and ensure stable installation.

[0037] Then, when a visitor approaches, the sensor 14 under the protective shell 1 detects the human signal, automatically wakes up the device, lights up the display screen 7, and starts the camera 12. The resident can view the visitor's video image through the display screen 7, and both parties can conduct two-way voice communication through the speaker 15 and microphone to confirm the visitor's identity.

[0038] Finally, during maintenance, the magnetic transparent plate 10 can be removed directly to clean the display screen 7. After cleaning, the transparent plate 10 can be reattached and fixed, which is convenient and quick. The threaded rod 6 can be rotated in the opposite direction to retract the pressure block 5 and remove the equipment from the groove for in-depth repair or replacement of parts. The entire disassembly process does not require damaging the wall.

[0039] 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.
