Description

Technical Field

[0001] This utility model belongs to the field of audiovisual system technology, specifically relating to an embedded modular audiovisual system processing device. Background Technology

[0002] In today's era of rapid information and intelligent development, embedded modular audiovisual systems are widely used in numerous fields such as conference offices, education and training, command and dispatch, and smart homes. These systems integrate audio and video processing functions into modular devices, enabling flexible deployment and functional expansion to meet diverse scenario requirements. However, existing embedded modular audiovisual systems still face many unresolved issues regarding display connection structure, system integration, and functional stability.

[0003] Regarding display screen connection structures, traditional embedded modular audiovisual systems mostly employ connection methods such as fixed clips, bolts, and nuts. While fixed clip connections are convenient to install, they lack versatility, making it difficult to adapt to displays of different sizes and thicknesses. Furthermore, the clips are prone to elastic fatigue after prolonged use, leading to loosening. Bolt and nut connections, while providing a certain level of connection strength, require repeated tightening of the nuts during installation, which is cumbersome and time-consuming. In vibration environments, the nuts are prone to loosening due to resonance, causing problems such as increased gaps at display splicing points and image misalignment, severely impacting audiovisual effects and system stability. In addition, some connection structures are designed with excessive complexity in pursuit of stability, occupying a large space and increasing the difficulty and cost of embedded system integration.

[0004] To address this, we propose an embedded modular audiovisual system processing device that not only enables rapid connection but also offers high efficiency, versatility, and flexibility, while also providing excellent anti-loosening performance. Utility Model Content

[0005] The purpose of this invention is to provide an embedded modular audio-visual system processing device that not only enables rapid connection but also has high efficiency, versatility, and flexibility, and secondly, excellent anti-loosening performance.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] An embedded modular audio-visual system processing device includes an audio-visual integrated platform, which is composed of multiple modular displays connected by connecting components.

[0008] The connecting assembly includes a U-shaped latch arm mounted on one of the displays and a base plate mounted on the other display. A pin seat is provided on the top of the base plate, and the pin seat is hinged to a handle via a pin. A connecting shaft is provided on the handle, and a retaining ring is movably mounted on the connecting shaft. The retaining ring is provided with a threaded section, and a first adjusting locking nut and a second adjusting tightening nut are provided on the threaded section. Multiple locking holes are arrayed on the outer sides of both the first adjusting locking nut and the second adjusting tightening nut. Elastic components are provided on both sides of the connecting shaft, and locking rods that are inserted into the locking holes are provided on the elastic components.

[0009] Furthermore, a support frame is provided on the back of the audio and video integrated platform.

[0010] Furthermore, the first adjusting locking nut and the second adjusting tightening nut are cylindrical.

[0011] Furthermore, a PVC sleeve is fitted onto the handle.

[0012] Furthermore, the elastic component includes a hollow cylinder rotatably mounted on the connecting shaft, a spring is disposed inside the hollow cylinder, a piston disc is disposed on one side of the spring, a movable rod is mounted on one side of the piston disc, and the end of the movable rod away from the piston disc passes through the hollow cylinder and is connected to a locking rod.

[0013] Furthermore, the locking lever matches the locking hole.

[0014] Furthermore, the audio-visual integrated platform includes a housing, a display screen is installed on one side of the housing, and a touch module, an audio amplification module, a conference whiteboard module, a conference discussion module, and a video monitoring module are embedded inside the housing.

[0015] The technical effects achieved by this utility model are as follows:

[0016] 1. During the assembly of the audio-visual integrated platform, based on the size and installation gap of the displays to be spliced, the relative positions of the first adjusting locking nut and the second adjusting tightening nut on the threaded section of the retaining ring are changed by rotating them, thereby driving the retaining ring to move axially on the connecting shaft. This process allows for flexible adjustment of the effective engagement length of the retaining ring to adapt to the splicing requirements of displays of different specifications, improving the system's versatility and installation flexibility.

[0017] 2. Align the buckle with the U-shaped latch arm, allowing it to engage within the opening. Then, press down on the handle. The handle rotates around the pin, using the pin seat as a fulcrum, causing the connecting shaft to move downwards along an arc. During this process, the buckle and the U-shaped latch arm engage tightly, achieving an initial mechanical connection between the two displays and forming a stable splicing base structure. After the initial connection is complete, further rotate the first adjusting locking nut and the second adjusting tightening nut, bringing them closer together on the threaded section. The axial pressure of the nuts firmly fixes the relative position of the buckle and the connecting shaft, ensuring no loosening gaps between the buckle and the U-shaped latch arm. Simultaneously, during nut rotation, the locking rod, under the compression spring force of the elastic component, precisely embeds into the locking hole on the outside of the nut. When the locking rod is fully inserted into the locking hole, a mechanical limit is formed, preventing the nut from rotating due to external vibration or force, thus effectively preventing nut loosening and significantly improving the anti-loosening performance of the connecting assembly in complex vibration environments.

Detailed Implementation

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-4As shown, an embedded modular audio-visual system processing device includes an audio-visual integrated platform 1, which is composed of multiple modular displays 2, which are connected by connecting components.

[0026] The connecting assembly includes a U-shaped latch arm 3 mounted on one of the displays 2 and a base plate mounted on the other display 2. A pin seat 4 is provided on the top of the base plate. The pin seat 4 is hinged to the handle 5 via a pin. A connecting shaft 6 is provided on the handle 5. A buckle 7 is movably provided on the connecting shaft 6. A threaded section 8 is provided on the buckle 7. A first adjusting locking nut 9 and a second adjusting tightening nut 10 are provided on the threaded section 8. Multiple locking holes 11 are arrayed on the outer sides of both the first adjusting locking nut 9 and the second adjusting tightening nut 10. Elastic components are provided on both sides of the connecting shaft 6. A locking rod 12 inserted into the locking hole 11 is provided on the elastic component.

[0027] The audio-visual integrated platform 1 has a support frame 13 on its back. The support frame 13 can be connected to an external support frame 13 by bolts for support, thus enabling the connection of multiple modules.

[0028] Meanwhile, the first adjusting locking nut 9 and the second adjusting locking nut 10 are cylindrical, which facilitates the opening of the array of locking holes 11 and makes locking convenient.

[0029] A PVC sleeve is fitted onto the handle 5 to facilitate its use.

[0030] The elastic component includes a hollow cylinder 14 rotatably mounted on a connecting shaft 6. A spring 15 is installed inside the hollow cylinder 14. A piston disc 16 is installed on one side of the spring 15. A movable rod 17 is installed on one side of the piston disc 16. The end of the movable rod 17 away from the piston disc 16 passes through the hollow cylinder 14 and is connected to a locking rod 12. In use, by pulling the locking rod 12, the locking rod 12 drives the movable rod 17 to stretch the piston disc 16 and the spring 15, thereby displacing it and allowing the locking rod 12 to be pulled out from the locking hole 11 for use. When locking, the spring 15 causes the locking rod 12 to enter the locking hole 11 for locking.

[0031] The locking lever 12 is matched with the locking hole 11. Matching means that the locking lever 12 can enter the interior of the locking hole 11.

[0032] The audio-visual integrated platform 1 includes a housing, a display screen 2 installed on one side of the housing, and a touch module, an audio amplification module, a conference whiteboard module, a conference discussion module and a video monitoring module embedded inside the housing.

[0033] The audio amplification module supports beamforming microphone arrays, DSP audio processing, and power amplifier output, which can be implemented through embedded audio codecs (such as ADI SHARC DSP).

[0034] The whiteboard module supports 20-point touch and gesture recognition via infrared / capacitive touch, which can be achieved through an integrated touch controller (Synaptics Touch IC).

[0035] The conference discussion module supports access to digital discussion units, speech management, and simultaneous interpretation channel allocation, which can be achieved through an audio network protocol based on Dante / AES67.

[0036] The video conferencing module can support the integration of PTZ cameras, AI framing, and codec engines (H.265 / AV1), which can be implemented through a dedicated VPU (such as Intel Movidius).

[0037] The whiteboard collaboration module supports real-time handwriting rendering, content OCR recognition, and QR code sharing, which can be achieved through a low-latency handwriting engine (prediction algorithm + GPU acceleration).

[0038] The environmental control module controls devices such as lights, curtains, and air conditioners via RS-485 / CEC, which can be achieved by integrating an IoT gateway (supporting KNX / Crestron protocols).

[0039] The internal embedded controller uses a combination of CPU+GPU+FPGA (such as Xilinx Zynq UltraScale+) to achieve: real-time video encoding and decoding (4x4K@60fps), low-latency image stitching (<2ms), and AI edge computing (face recognition, voice noise reduction).

[0040] Unified management platform: Built-in Linux OS + containerized application framework (Docker), supporting: module status monitoring, networked firmware upgrade (OTA), and API interface opening (integration with third-party systems).

[0041] It should be noted that the structure and working principle of the touch module, audio amplification module, conference whiteboard module, conference discussion module and video monitoring module in this utility model are all existing technologies, and will not be elaborated on here.

[0042] The working principle of this utility model is as follows: During the assembly of the audio-visual integrated platform 1, based on the size and installation gap of the display screen 2 to be spliced, the relative positions of the first adjusting locking nut 9 and the second adjusting tightening nut 10 on the threaded section 8 of the buckle 7 are changed by rotating them, thereby driving the buckle 7 to move axially on the connecting shaft 6. This process can flexibly adjust the effective fastening length of the buckle 7 to adapt to the splicing requirements of different specifications of display screens 2, improving the versatility and installation flexibility of the system. Align the buckle 7 with the U-shaped latch arm 3 so that the buckle 7 is inserted into the opening of the U-shaped latch arm 3. Then, press down on the handle 5, and the handle 5 rotates around the pin shaft seat 4 as the fulcrum, driving the connecting shaft 6 to move downward along an arc trajectory. During this process, the buckle 7 and the U-shaped latch arm 3 are tightly engaged, achieving a preliminary mechanical connection between the two displays 2 and forming a stable splicing base structure. After the preliminary connection is completed, the first adjusting locking nut 9 and the second adjusting tightening nut 10 are further rotated, bringing them closer together on the threaded section 8. The axial pressure of the nuts firmly fixes the relative position of the buckle 7 and the connecting shaft 6, ensuring that there is no loosening gap between the buckle 7 and the U-shaped latch arm 3. At the same time, during the rotation of the nut, the locking rod 12 is precisely embedded into the locking hole 11 on the outside of the nut under the elastic force of the compression spring 15 of the elastic component. When the locking rod 12 is fully inserted into the locking hole 11, a mechanical limit is formed, preventing the nut from rotating due to external vibration or external force, thereby effectively preventing the nut from loosening and significantly improving the anti-loosening performance of the connecting component in complex vibration environments. This device not only enables rapid connection but also has high efficiency, versatility, and flexibility, and secondly, excellent anti-loosening performance.

[0043] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
