Description

Technical Field

[0001] This utility model relates to the field of video matrix technology, and in particular to a multi-interface video matrix with video compression encoding and splicing functions. Background Technology

[0002] Video matrices are key devices in modern audio-visual systems, enabling flexible scheduling of multiple signals. Their technological background stems from the need for efficient signal management across various scenarios. In early systems, the fixed connection between a single signal source and the display device was insufficient for complex scenarios. Video matrices, through internal switching circuits, support the on-demand distribution of multiple input signals to different display terminals, achieving flexible "one-to-many" or "many-to-many" control. With technological advancements, digital matrices have replaced traditional analog matrices, supporting not only high-definition and even 4K video transmission but also simultaneous audio signal processing. They also possess functions such as automatic signal recognition and format conversion, ensuring compatibility and stability between different devices.

[0003] Modern video matrix technology integrates hardware optimization and intelligent control. On the hardware side, it employs a modular design, allowing users to expand input and output channels as needed, adapting to different scales from small conference rooms to large command centers. On the software side, it simplifies operation through graphical interfaces or mobile applications, supporting automated functions such as scene presets and timed switching. Furthermore, networking trends enable video matrices to connect to local area networks or the internet, achieving remote signal dispatching and multi-location collaborative control. Combined with intelligent analysis technology, it can automatically trigger display priorities based on content type, improving system response efficiency and intelligence.

[0004] Patent document CN220570579U discloses a multi-interface video matrix with video compression encoding and splicing functions. It includes an outer frame, a baffle fixedly connected to the top surface of the outer frame, an air vent below the baffle, heat dissipation holes on the sides of the outer frame, a heat dissipation plate fixedly connected to the sides of the outer frame, a fan and a chilled water tank at the bottom of the outer frame, an air duct at the air outlet of the fan, a diffuser connected to the end of the air duct, a ventilation frame fixedly connected to the outer frame, fans arranged around the ventilation frame, a matrix body mounted on the ventilation frame, a heat-conducting plate on the side of the matrix body, and a heat-conducting rod fixedly connected to the outer side of the heat-conducting plate. The advantages of this invention are: the airflow direction within the outer frame follows the natural flow direction of hot air, resulting in faster airflow and accelerated cooling inside the outer frame, leading to better cooling effect and higher practicality.

[0005] As in the prior art of the aforementioned patent, heat dissipation is enhanced by placing a matrix inside the housing and then opening heat dissipation holes on the periphery of the housing. However, this method of setting up the matrix occupies a large space and makes it inconvenient to maintain the internal matrix. Furthermore, the matrix is ​​generally composed of multiple modules, and signal transmission lines and power cables need to be plugged into multiple modules. However, since the matrix is ​​placed inside the housing, it is not easy to plug them in. On the other hand, if the plug-in parts of each module are placed on the outside, dust will accumulate on the plug-in parts of each module when it is not in use, which is also a problem that needs to be considered. Utility Model Content

[0006] The purpose of this invention is to provide a multi-interface video matrix with video compression encoding and splicing functions to solve the above-mentioned shortcomings in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a multi-interface video matrix with video compression encoding and splicing functions, comprising matrix modules and a housing, wherein the housing has an internal mounting cavity, and multiple matrix modules are installed inside the mounting cavity, with bolts threaded onto both ends of the multiple matrix modules, and threaded holes corresponding to the bolts are provided on both sides of the housing, the multiple matrix modules are fixedly connected to the housing through bolts and threaded holes, and dustproof plates are respectively provided on the multiple matrix modules, and heat dissipation components are provided on the peripheral wall of the housing.

[0008] As a further description of the above technical solution: the heat dissipation component includes a heat dissipation fan, which is disposed on the rear side of the housing. Multiple heat dissipation slots are provided on both sides of the housing, and there is a certain heat dissipation space between the heat dissipation fan and the multiple matrix modules.

[0009] As a further description of the above technical solution: the matrix module is provided with a plug-in part, the dustproof plate has a groove on the side near the matrix module, the groove covers the plug-in part, and the rear side of the housing has multiple through slots for plugging in power cords.

[0010] As a further description of the above technical solution: an extension is provided at the upper and lower ends of one side of the housing, a mounting groove is formed between two of the extensions, a connecting shaft is fixedly installed between the mounting grooves, a plurality of rotating shafts are rotatably installed on the connecting shaft, and one end of the dustproof plate is fixedly connected to the rotating shaft.

[0012] As a further description of the above technical solution: a locking element is threadedly installed on the dustproof plate, one end of which is located inside the mounting groove, and the locking element is tightly attached between the housing and the rotating shaft.

[0013] This invention provides a multi-interface video matrix with video compression encoding and splicing functions. It offers the following advantages: by installing multiple matrix modules separately inside the mounting cavity, only the corresponding matrix module needs to be disassembled for maintenance, unlike existing technologies where the entire matrix needs to be disassembled. Furthermore, the heat dissipation component provides cooling, and the dustproof plate individually protects the connectors on each matrix module from dust, thus increasing dustproof performance.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A multi-interface video matrix with video compression encoding and splicing functions includes matrix modules 3 and a housing 1. The housing 1 has an internal mounting cavity 2, and multiple matrix modules 3 are installed inside the mounting cavity 2. Bolts 5 are threaded onto both ends of each matrix module 3. Screw holes 6, corresponding to the bolts 5, are provided on both sides of the housing 1. The multiple matrix modules 3 are fixedly connected to the housing 1 via the bolts 5 and screw holes 6. Dustproof plates 13 are respectively installed on each matrix module 3. A heat dissipation assembly is provided on the peripheral wall of the housing 1. By installing multiple matrix modules 3 separately inside the mounting cavity 2, when maintenance is required, only the corresponding matrix module 3 needs to be disassembled. Compared to existing technologies, it is not necessary to disassemble the entire matrix module. Furthermore, the heat dissipation assembly can dissipate heat, and the dustproof plates 13 can individually protect the insertion holes on each matrix module 3 from dust, increasing dustproof performance.

[0026] As a preferred technical solution of this embodiment, the heat dissipation component includes a heat dissipation fan 8, which is disposed on the rear side of the housing 1. Multiple heat dissipation slots 7 are provided on both sides of the housing 1. There is a certain heat dissipation space between the heat dissipation fan 8 and the multiple matrix modules 3. The heat dissipation fan 8 can blow out the heat inside the housing 1 and dissipate it through the heat dissipation slots 7.

[0027] As a preferred technical solution of this embodiment, the matrix module 3 is provided with a plug-in part 4, and the dustproof plate 13 has a groove 15 on the side near the matrix module 3. The groove 15 covers the plug-in part 4, and the rear side of the housing 1 has a plurality of through slots 9 for plugging in power cords. By covering the plug-in part 4 inside the groove 15, dust prevention can be achieved, and power cords can be connected through the rear through slots 9 to supply power to multiple modules.

[0028] As a preferred technical solution of this embodiment, extension portions 102 are provided at the upper and lower ends of one side of the housing 1, and a mounting groove 103 is formed between two extension portions 102. A connecting shaft 11 is fixedly installed between the mounting grooves 103, and a plurality of rotating shafts 12 are rotatably installed on the connecting shaft 11. One end of the dustproof plate 13 is fixedly connected to the rotating shaft 12. By rotating the dustproof plate 13, the dustproof plate 13 can be rotated on the connecting shaft 11.

[0029] As a preferred technical solution in this embodiment, a magnetic suction plate 10 is fixedly installed on the side of the housing 1 near the rotating shaft 12. When the dustproof plate 13 rotates to the side wall position of the housing 1, it is magnetically connected to the magnetic suction plate 10. When the dustproof plate 13 is opened, it is attracted by the magnetic suction plate 10, thereby ensuring that multiple matrix modules 3 can be used normally.

[0030] As a preferred technical solution in this embodiment, a locking member 14 is threadedly installed on the dustproof plate 13. One end of the locking member 14 is disposed inside the mounting groove 103, and the locking member 14 is tightly attached between the housing 1 and the rotating shaft 12. Tightening the locking member 14 so that the end of the locking member 14 is stuck between the rotating shaft 12 and the housing 1 can prevent the dustproof plate 13 from rotating and can keep it in a state of contact with the matrix module 3. When the locking member 14 is loosened so that the end of the locking member 14 leaves the space between the rotating shaft 12 and the housing 1, the dustproof plate 13 can be rotated freely.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
