[0001] The utility model relates to the field of access control systems, in particular to an indoor unit with a compact structure. Background Art

[0002] In modern residential and commercial buildings, access control systems have become an important security feature. Access control systems usually consist of an outdoor unit installed at the entrance of a building and an indoor unit installed in the resident's room. These systems are designed to control access rights and ensure that only authorized personnel can enter the building.

[0003] Traditional access control system indoor units usually include a communication module, a user interface and related electronic circuits. For example, the Chinese utility model with announcement number CN202634589U discloses a door machine. From a functional point of view, although the door machine has basic interaction and communication functions, it may face challenges such as low space utilization, poor heat dissipation and complex wiring due to unreasonable internal layout, and cannot meet the high requirements of smart homes. The internal structure needs to be optimized to improve stability, convenience and aesthetics.

[0004] The present invention aims to provide an indoor unit with a compact structure, which is not only fully functional but also compact in structure, easy to install and maintain, and more adaptable to the needs of contemporary smart homes. Utility Model Content

The design of the indoor unit aims to provide an indoor unit of an intelligent access control system with a compact structure, easy installation and maintenance, so as to meet the needs of modern smart homes.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an indoor unit with a compact structure, including a body provided with a partition, the middle part of the partition is set to be hollow, a cover plate and a touch screen are installed on one side of the body, and a back cover is installed on the other side of the body, a first control panel is arranged in the hollow part of the partition, a second control panel is arranged in the back cover, and a plurality of wiring structures are arranged on the partition and on one side facing the back cover, the touch screen is electrically connected to the first control panel through signal lines and after being arranged by the wiring structure, and the first control panel is electrically connected to the second control panel through signal lines and after being arranged by the wiring structure.

[0007] Based on the above, firstly, by providing a body with a partition and placing the first control board in the hollow of the partition, the compact structure of the indoor unit is achieved; secondly, the signal lines are neatly arranged by using a wire management structure, which not only improves the orderliness of the lines, but also facilitates maintenance and upgrading, and prolongs the service life of the product; thirdly, the simple installation method of the touch screen and the back cover reduces the after-sales cost and improves the user experience; in addition, by providing an antenna and a microphone on the inner side of the body frame, and arranging a speaker on the side of the back cover corresponding to the partition, the functionality of the indoor unit is greatly enhanced; finally, the bolt locking is achieved through the back cover card slot on the inner side of the body frame and the groove on the back cover, and the first control board is matched on the mounting protrusion through the mounting notch in the partition, which further improves the stability of the structure and the flexibility of installation. In summary, the indoor unit of the utility model has a compact structure, diverse functions, is easy to install and maintain, and has a high practical value.

[0008] Furthermore, an antenna and a microphone are arranged on the inner side of the frame of the body, and a speaker is also arranged on the side of the partition facing the back cover. The antenna, the microphone and the speaker are respectively connected to the first control board through signal lines and arranged by the wiring structure.

[0009] Based on the above, the utility model realizes multi-functional integration and maximizes space utilization by arranging an antenna and a microphone on the inner side of the body frame, arranging a speaker on the side of the partition facing the rear cover, and neatly connecting these components with the first control board through a wiring structure. Such a design not only provides efficient signal transmission and avoids signal interference, but also ensures an improved audio experience, making the assembly and maintenance process of the indoor unit easier, reducing production costs and improving the market value of the product. The design is ingenious and practical, fully reflecting the innovation and practicality of the utility model.

[0010] Furthermore, a mounting protrusion is provided on the hollow edge of the partition, and the first control panel is fitted on the mounting protrusion via a mounting notch provided on the edge thereof.

[0011] Based on the above, by setting a mounting protrusion on the hollow edge of the partition and allowing the first control panel to fit on the mounting protrusion through the mounting notch on its edge, the utility model creates a stable and precise installation solution. This design ensures that the first control panel is properly and firmly placed in the hollow part of the partition. The direct effect brought about by this is that the stability of the control panel is enhanced, and the tightness and durability of the overall structure are also significantly improved. At the same time, due to the mutual cooperation between the mounting notch and the mounting protrusion, the connection between the control panel and the partition is more precise and reliable, which helps to improve the safety performance of the product and extend its service life. In addition, this simple and efficient installation method also reduces the cost of production and maintenance, making the utility model more economically valuable.

[0012] Furthermore, a rear cover slot is provided on the inner side of the frame of the body, and a groove matching the rear cover slot is provided on one side of the rear cover. When installing the rear cover, the groove is slid into the rear cover slot, and then the rear cover is locked by bolts.

[0013] Based on the above, by setting a back cover card slot on the inner side of the body frame and configuring a groove that matches it on one side of the back cover, the utility model provides a simple and effective installation method. In actual operation, it is only necessary to slide the groove into the back cover card slot, and then use bolts to lock the back cover to complete the installation. This design greatly simplifies the installation process and reduces the difficulty of installation. It also improves the accuracy of installation and ensures the stability of the connection between the body and the back cover. In addition, this structure is also easy to disassemble and maintain, thereby further extending the service life of the product and reducing the cost of after-sales service. Overall, this design improves the user-friendliness of the product while taking into account practicality and economy.

[0014] Furthermore, a mounting cavity adapted to the second control board is provided in the middle of the back cover, buckles are provided around the mounting cavity, the second control board is fixed in the mounting cavity by the buckles, and the mounting cavity is also provided with a plurality of wiring ports.

[0015] Based on the above, by setting a mounting cavity compatible with the second control board in the middle of the back cover, the utility model realizes the stable installation of the second control board. The buckles arranged around the mounting cavity further ensure the fixation of the second control board, thereby providing reliable mechanical support and protection. Such a design not only facilitates the installation and disassembly of the second control board, but also facilitates the heat dissipation of the control board and the management of the circuit. The setting of the wiring port makes the circuit connection more flexible and orderly, which helps to improve the safety of the circuit and the convenience of maintenance. In general, this design demonstrates an excellent engineering design concept, which pays attention to both functionality and practicality, thereby improving the performance and market competitiveness of the overall product.
