[0002] With the development of the times, the rise of modular and splicable audio and video control box technology stems from the increasing contradiction between the inherent defects of traditional audio and video equipment and market demand and technological development. In different application scenarios such as multimedia conference halls, broadcasting and television projects, and command and control centers, users have significantly different requirements for the signal input and output types, processing capabilities, and other functions of audio and video equipment. The demand for flexible combination of functional modules on demand and optimized resource utilization to avoid waste is becoming increasingly strong. The traditional audio and video control boxes currently in use allow users to issue control commands through built-in physical buttons, knobs, or a matching remote control. The commands are transmitted to the core processing module through the internal integrated control circuit, enabling real-time feedback and adjustment of parameters such as volume adjustment, input source switching, and screen brightness and contrast adjustment. Finally, the processed and adjusted audio and video signals are transmitted to devices such as monitors, projectors, speakers, and amplifiers through fixed audio output interfaces to complete the final presentation. While existing traditional audio and video control boxes enable audio and video control, they cannot be modularized and spliced, nor can they be fixed to the carrier. Therefore, a modular and splicable audio and video control box is proposed to solve the above problems. Utility Model Content

Detailed Implementation
[0009] 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.
[0010] Reference Figures 1-3 This utility model provides an embodiment of a modular, splicable audio-visual control box, including a shell 1. The shell 1 serves as the basic load-bearing structure of the entire audio-visual control box and is made of high-strength ABS engineering plastic with certain insulation properties. It has a cuboid shape and a precisely reserved internal installation space to accommodate various audio-visual processing modules, circuit components, and connection structures. A front panel 2 is slidably connected to the front of the shell 1. The front panel 2 is made of lightweight aluminum alloy and anodized, giving it a delicate matte texture. It not only possesses excellent wear resistance and corrosion resistance but also coordinates with the appearance of the shell 1. A rear panel 16, also made of aluminum alloy, is slidably connected to the rear of the shell 1. Its main function is to provide rear protection and interface installation support for the control box. Multiple evenly distributed fixing bolts 3 are fixedly connected to the front of the front panel 2 and the rear of the rear panel 16. Made of stainless steel, the 3-shell housing features high strength, high hardness, and excellent rust resistance, ensuring long-term stable fixation. Sliding frames 11 are fixedly connected to both sides of the outer shell 1, effectively preventing the sliding plate 12 from exceeding its preset range during sliding and avoiding damage or connection failure due to excessive sliding. The sliding plate 12 is slidably connected to the inner side of the sliding frame 11, allowing the splicing shell 7 to move left and right, thus enabling splicing and separation operations between different control boxes. Push rods 13 are slidably connected to the top side of the sliding frame 11. When the position of the sliding plate 12 needs to be fixed, push the push rod 13 so that its bottom fits tightly against the groove on the top side of the sliding plate 12, locking the sliding plate 12 through friction. When the position of the sliding plate 12 needs to be adjusted, push the push rod 13 in the opposite direction to reduce friction, allowing the sliding plate 12 to slide within the sliding frame 11. The bottom side of the push rod 13 is slidably connected to the top side of the sliding plate 12.
[0011] Reference Figures 3-5 A magnetic chuck 17 is slidably connected to the top side of the outer casing 1. The main function of the magnetic chuck 17 is to provide an installation carrier and support structure for the magnet 18, the positioning buckle 8, and the locking rod 9. The magnetic chuck 17 has a certain protective function, which can protect the internal magnet 18 and other components from external collisions and damage. The positioning buckle 8 is slidably connected to the top side of the magnetic chuck 17. The main function of the positioning buckle 8 is to position the magnetic chuck 17 on the top side of the outer casing 1. When the magnetic chuck 17 slides to the appropriate position, the positioning buckle 8 is pressed to insert it into the corresponding positioning hole, which can fix the magnetic chuck 17 in that position and prevent it from shifting during subsequent operations. The magnet 18 is slidably connected to the top side of the magnetic chuck 17. The main function of the magnet 18 is to fix it to the device to be controlled by the attraction of the magnetic field when multiple control boxes are spliced together, so that they are tightly attracted together, enhancing the overall stability and connection strength after splicing, and at the same time assisting the fixing bolt 3 to achieve a more reliable fixing effect. In addition, the magnet 18 has permanent magnetism, requires no additional power supply, is easy to use and has low maintenance costs. The magnetic holder 17 has locking rods slidably connected to the front and rear sides. After the magnet 18 slides to the appropriate position, the locking rod 9 is pushed to make its inner side fit tightly against the inner side of the magnet 18. The magnet 18 is fixed in this position by friction, preventing the magnet 18 from shifting during use. The inner side of the locking rod 9 is slidably connected to the inner side of the magnet 18.
[0012] Reference Figures 1-5A splicing shell 7 is fixedly connected to the right side of the sliding plate 12. It is made of the same ABS engineering plastic as the outer shell 1, and its structural design is compatible with the outer shell 1. The main function of the splicing shell 7 is to serve as a connecting transition component between adjacent control boxes when multiple control boxes are spliced together, filling the gaps between them. Connection ports 4 are installed on the outer sides of both the front plate 2 and the splicing shell 7. The outer shell 1 is made of high-temperature resistant and wear-resistant engineering plastic, and the internal metal contacts are gold-plated, providing excellent conductivity and oxidation resistance. This ensures the stability and reliability of signal transmission and reduces signal attenuation and interference. Rotary adjustment wheels 6 are installed on the outer sides of both the front plate 2 and the splicing shell 7. These wheels are made of rubber with an anti-slip texture, increasing friction between the operator's hand and the adjustment wheel for easy rotation and adjustment, while also providing a good feel. Multi-functional sockets 5 are installed on the outer sides of both the front plate 2 and the splicing shell 7. The main function of the multi-functional sockets 5 is to provide diverse external device connection methods for the control box, expanding its applicability and enabling compatibility with more types of audio and video equipment. Both the rear panel 16 and the rear side of the splicing shell 7 are equipped with communication transmission ports 10. When multiple control boxes are spliced together, the audio and video signals and control signals inside each control box can be aggregated and distributed through the communication transmission ports 10 and the corresponding connectors 15, realizing the coordinated work of the entire splicing system and improving the efficiency of audio and video processing and transmission. Connectors 15 are installed on the outside of the communication transmission ports 10, which can realize the precise docking of the connectors 15 with the corresponding connectors 15 on adjacent control boxes. Even if there is a slight positional deviation during the splicing process, it can still be achieved through transmission extension. The adjustment of the expansion joint 14 compensates for the connection reliability. The transmission expansion joint 14 is fixedly connected to the inside of the connector 15 to provide expansion margin for the connection between the connectors 15, which facilitates position adjustment during the splicing process, ensures that the connectors 15 can be smoothly connected, and protects the internal transmission cable from external pulling and damage, ensuring stable transmission of audio and video signals and data signals. The transmission expansion joint 14 is fixedly connected to the inside of the connector 15. The top side of the magnetic bracket 17 has multiple evenly distributed positioning holes, and the positioning buckle 8 is slidably connected to the inside of the positioning holes.
[0013] Working principle: First, the cuboid outer shell 1 serves as the core load-bearing foundation, with a precisely reserved internal installation space to accommodate core components such as audio and video processing modules and circuit elements. Simultaneously, the panel provides both protection and interface installation. During multi-box splicing operations, the sliding frames 11 on the left and right sides of the outer shell 1 provide guiding constraints for the sliding plate 12. Pushing the sliding plate 12 moves the splicing shell 7 on its right side laterally. When multiple control boxes are spliced, the splicing shell 7 fills the gaps between adjacent boxes, forming a transitional connection structure. To fix the splicing position, push the push rod 13 on the top side of the sliding frame 11, making its bottom fit tightly against the groove on the top side of the sliding plate 12, locking the sliding plate 12 through friction. For adjustment, push the push rod 13 in the opposite direction to reduce friction, thus readjusting the position of the sliding plate 12. The magnetic bracket 17 is installed on the top side of the housing 1. The magnetic bracket 17 is fixed by pressing the positioning buckle 8 into the positioning hole on the top side of the magnetic bracket 17. Then, the magnetic attraction generated by the magnet 18 on its top side tightly attracts the spliced whole to the target device, enhancing the connection strength. If it is necessary to fix the position of the magnet 18, push the locking rod 9 on the front and rear sides of the magnetic bracket 17 so that its inner side is in contact with the inner side of the magnet 18. The friction prevents the magnet 18 from shifting. The connection port 4 between the front plate 2 and the outer side of the splicing shell 7 ensures stable signal transmission and reduces attenuation interference. The multi-functional socket 5 supports the docking of various external audio and video devices, expanding the scope of application. The rotating adjustment wheel 6 allows the operator to manually adjust the parameters. After multiple boxes are spliced together, the rear panel 16 and the communication transmission port 10 on the rear side of the splicing shell 7 are connected to adjacent boxes through the outer connector 15. The transmission expansion joint 14 on the inner side of the connector 15 can provide expansion and contraction margin. Even if there is a slight positional deviation in the splicing, it can be compensated by expansion and contraction adjustment to ensure accurate docking. Finally, the audio and video signals and control signals of each box are collected and distributed to realize the collaborative work of the entire splicing system and efficiently complete the audio and video control and signal processing transmission tasks.
