Description

Technical Field

[0001] This utility model relates to the field of audio and video equipment technology, and more specifically, to a modular audio and video repeater connection structure. Background Technology

[0002] In the field of audio and video equipment technology, with the continuous expansion of multimedia application scenarios, such as conference systems and monitoring audio acquisition, higher requirements are placed on the stable transmission and efficient processing of audio and video signals. Patent application number 201210061968.6 discloses a wireless audio system for centralized transmission of multiple voice channels. This system receives and processes audio signals via a remote wireless repeater and transmits them to a remote control platform, thus achieving centralized transmission of multiple voice channels to a certain extent.

[0003] However, traditional audio and video transmission equipment still faces many limitations in practical applications. This is especially true when using multiple repeater modules in combination, where traditional equipment presents significant challenges. Firstly, their structure is typically fixed. Like the aforementioned wireless audio systems built around specific Zigbee or mobile communication networks, the layout and connection methods of each repeater module are fixed, making it difficult to flexibly adjust the number and combination of repeater modules according to the signal processing capabilities and transmission distance requirements of different scenarios. When the application scenario has special requirements for signal transmission frequency bands and transmission methods, this fixed structure is even more difficult to meet, resulting in poor equipment versatility and an inability to combine multiple repeater modules as needed to optimize signal transmission performance.

[0004] On the other hand, the high integration of functional modules and their tight coupling result in a lack of standardized interface design. In practice, it is difficult to achieve fast and stable connections between different repeater modules. Not only is it impossible to flexibly add or remove repeater modules based on actual signal transmission distance and strength, but forced combinations can also easily lead to signal incompatibility and poor contact. If signal attenuation is severe during long-distance transmission, and repeater modules cannot be easily added to strengthen the signal, it will result in poor signal transmission stability and scalability, affecting the quality of audio and video transmission. Simultaneously, the complex device connection methods make signal interfacing between repeaters and other devices inconvenient. During the combination of multiple repeater modules, signal interruptions and transmission delays are highly likely, reducing equipment efficiency and potentially affecting the normal operation of the entire audio and video transmission system due to unstable connections. Therefore, there is an urgent need to design a more flexible, efficient, and stable modular audio and video repeater connection structure to address the shortcomings of existing technologies in the combination of multiple repeater modules and meet diverse audio and video transmission needs. Utility Model Content

[0005] The purpose of this invention is to provide a modular audio and video repeater connection structure to solve the problem mentioned in the background art of difficulty in flexibly adjusting the number and combination of repeater modules according to the requirements of signal processing capabilities and transmission distances in different scenarios.

[0006] To achieve the above objectives, this utility model provides a modular audio / video repeater connection structure, including a housing, a sealing cover detachably installed on the top of the housing, and a plurality of repeater modules connected in series inside the housing. Each repeater module has an input terminal on one side and an output terminal on the other side. One end of each output terminal is equipped with a docking block, and the other end of each output terminal is equipped with a docking groove. Adjacent output terminals are connected to each other through the docking block and the docking groove. The repeater modules are locked and positioned by a locking assembly after being connected in series.

[0007] This feature includes a removable sealing cover on the top of the housing for easy installation and maintenance of the internal structure; the relay modules are physically connected in series via input terminals, output terminals, docking blocks, and docking slots; the locking assembly uses mechanical force to secure the connected modules and prevent loosening.

[0008] Preferably, both the docking block and the docking groove are provided with electrode contacts, and the docking block and the docking groove are connected through the electrode contacts.

[0009] This feature ensures that the electrode contacts of the docking block and the docking groove form a conductive path during physical docking, enabling the transmission of signals and electricity.

[0010] Preferably, the relay module has an input port on its outer side near the input end and an output port on its outer side near the output end.

[0011] This setting places the input and output ports on the outside of the relay module, facilitating connection to external devices.

[0012] Preferably, one end of the housing is provided with a power port, which is connected to the electrode contacts of the relay module at one end.

[0013] This setting connects the power port to the relay module via electrode contacts, distributing external power to each series module.

[0014] Preferably, the locking assembly includes a guide shell, inside which a lead screw is installed, a slider is mounted on the lead screw, and a pressure plate is mounted on the top of the slider, the pressure plate abutting against one end of the series relay module.

[0015] This setting allows the lead screw to rotate, causing the slider to move linearly within the guide housing, and the pressure plate to press the relay module.

[0016] Preferably, one end of the lead screw is connected to a handle.

[0017] This feature provides manual operating torque for the handle, simplifying the lead screw rotation process.

[0018] Preferably, the outer wall of the pressure plate is fitted with a soft pad.

[0019] This feature includes a soft pad on the outer wall of the pressure plate that provides cushioning and distributes pressure when in contact with the module.

[0020] Preferably, the top of the guide shell is provided with a strip-shaped guide opening, and the top of the slider slides in cooperation with the guide opening.

[0021] This feature uses a strip-shaped guide opening at the top of the guide housing to restrict the movement trajectory of the slider, ensuring that the pressure plate moves in a straight line.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This modular audio and video repeater connection structure effectively solves the problem of combining repeater modules in traditional audio and video transmission equipment through a series of innovative designs, and has significant technical effects.

[0024] In terms of structural flexibility, the casing houses several repeater modules that can be connected in series. Users can freely increase or decrease the number of repeater modules and flexibly adjust their combination according to the actual needs of signal processing capabilities and transmission distances in their usage scenarios. Whether it is short-distance audio transmission for small conferences or long-distance, complex-environment monitoring audio and video transmission, it can be combined as needed, greatly improving the versatility and adaptability of the equipment and breaking the limitations of the rigid structure of traditional equipment.

[0025] In terms of ease of connection and stability, the docking block and slot design at the output end of the repeater module, combined with the electrode contact docking method, enables fast and stable connections between different repeater modules. This standardized interface design avoids problems such as signal incompatibility and poor contact caused by the lack of standard interfaces in traditional equipment, ensuring efficient transmission of audio and video signals between repeater modules, reducing signal interruptions and transmission delays, and guaranteeing the stable operation of the entire audio and video transmission system. At the same time, the rational arrangement of input ports, output ports, and power ports further optimizes the connection process between the device and external devices, improving efficiency.

[0026] Furthermore, the locking assembly provides reliable positioning for the series-connected relay modules. By rotating the lead screw, the slider and pressure plate move, ensuring a tight fit against the relay module and preventing loosening or displacement during use, thus further enhancing the stability of the equipment. The soft pad design on the outer wall of the pressure plate ensures a secure fastening effect while preventing damage to the relay module, extending the service life of the equipment.

[0033] 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.

[0034] This utility model provides a modular audio / video repeater connection structure, such as... Figure 1 , Figure 4 As shown, the device includes a housing 1, with a detachable sealing cover 2 on the top. Inside the housing 1, several relay modules 4 are connected in series. Each relay module 4 has an input terminal 41 on one side and an output terminal 42 on the other side. One end of each output terminal 42 has a mating block 43, and the other end has a mating groove 44. Adjacent output terminals 42 are connected via the mating block 43 and the mating groove 44. The relay modules 4 are locked in place by a locking assembly 3. The relay module 4 uses a conventional relay circuit board design found in the prior art, and will not be described in detail here.

[0035] The removable sealing cover 2 on the top of the outer casing 1 is connected by snaps or threads, facilitating the installation and maintenance of the internal structure. The repeater module 4 is physically connected in series via an input end 41, an output end 42, a docking block 43, and a docking groove 44. The shapes of the docking block 43 and the docking groove 44 are complementary, such as rectangular or trapezoidal. The locking assembly 3 is driven by a lead screw 32, which generates axial pressure on the pressure plate 34 to fix the connected modules and prevent loosening. This forms a scalable modular architecture, allowing users to add or remove repeater modules 4 as needed to adapt to different transmission distances and signal strength requirements. The mechanical locking design ensures the stability of the module connection and avoids signal interruption caused by vibration or displacement.

[0036] In this embodiment, as Figure 4 As shown, electrode contacts are provided on both the docking block 43 and the docking groove 44, and the docking block 43 and the docking groove 44 are connected through the electrode contacts.

[0037] The electrode contacts of the mating block 43 and the mating groove 44 adopt a spring-loaded pogo pin or elastic copper sheet design, forming a conductive path during physical mating to achieve signal and power transmission. Electrical connection can be completed without additional wiring, simplifying the installation process; the standardized contact design ensures compatibility between different modules and avoids the signal attenuation problem of traditional interfaces.

[0038] Specifically, such as Figure 2 As shown, an input port 11 is provided on the outside of the relay module 4 near the input end 41, and an output port 12 is provided on the outside of the relay module 4 near the output end 42.

[0039] Input port 11 and output port 12 are located on the outside of repeater module 4, using standard interfaces such as HDMI, DP, or RCA, facilitating connection with external devices such as cameras and monitors. This enables convenient interface between modular devices and terminal devices, supporting audio and video signal input and output; the external interface design reduces internal circuit interference and improves signal quality.

[0040] Furthermore, such as Figure 2 As shown, a power port 13 is provided at one end of the outer casing 1, and the power port 13 is connected to the electrode contacts of the relay module 4 at one end.

[0041] Power port 13 connects to relay module 4 at one end via electrode contacts, distributing external power such as DC 12V to each series-connected module to form a daisy-chain power supply network. This creates a unified power supply network, eliminating the need for individual power supply to each module; the electrode contact connection method reduces contact resistance, lowering energy consumption and the risk of overheating.

[0042] Furthermore, such as Figure 3As shown, the locking assembly 3 includes a guide shell 31, a lead screw 32 is installed inside the guide shell 31, a slider 33 is installed on the lead screw 32, a pressure plate 34 is installed on the top of the slider 33, and the pressure plate 34 abuts against one end of the series relay module 4.

[0043] The rotation of the lead screw 32 drives the slider 33 to move linearly within the guide shell 31. The pressure plate 34 on the top of the slider 33 then presses against one end of the serially connected relay module 4, and the guide shell 31 is fixed to the inner wall of the outer shell 1. This provides controllable axial pressure to ensure a tight fit between modules; the self-locking characteristic of the lead screw drive ensures a stable and durable locking state, adapting to vibrations and impacts in complex environments.

[0044] Furthermore, such as Figure 3 As shown, a handle 35 is connected to one end of the lead screw 32.

[0045] The handle 35 is connected to one end of the lead screw 32 via a keyway or welding, providing manual operating torque and simplifying the rotation process of the lead screw 32. Locking and disassembling of the module can be completed without tools, improving maintenance efficiency; the ergonomically designed handle enhances operating comfort.

[0046] Furthermore, a soft pad is installed on the outer wall of the pressure plate 34.

[0047] The soft pads on the outer wall of the pressure plate 34 are made of silicone or EVA material, providing cushioning and dispersing pressure when in contact with the module. This prevents rigid contact from damaging the module housing; the friction of the soft pads enhances the clamping effect while absorbing micro-vibrations during equipment operation.

[0048] Furthermore, the top of the guide shell 31 is provided with a strip-shaped guide opening, and the top of the slider 33 slides in cooperation with the guide opening.

[0049] The strip-shaped guide opening at the top of the guide housing 31 restricts the movement trajectory of the slider 33. The protrusion at the top of the slider 33 slides in conjunction with the guide opening to ensure the linear movement of the pressure plate 34. This avoids uneven clamping caused by slider offset; the limiting function of the guide opening enhances structural stability and extends the service life of the lead screw 32 and the slider 33.

[0050] In use, the modular audio / video repeater connection structure of this utility model first opens the removable sealing cover 2 on the top of the outer casing 1. The sealing cover 2 is separated from the outer casing 1 by a snap-fit ​​or threaded connection, providing space for internal operation. According to the actual audio / video transmission requirements, a corresponding number of repeater modules 4 are connected in series. Specifically, the docking block 43 on one side of the output terminal 42 of the repeater module 4 is physically docked with the docking slot 44 on the other side of the output terminal 42 of the adjacent repeater module 4. The docking block 43 and the docking slot 44 have complementary shapes (such as rectangular or trapezoidal) to achieve precise splicing. Simultaneously, the electrode contacts (spring pins or elastic copper sheets) on the docking block 43 and the docking slot 44 contact each other during docking, forming a conductive path and completing the electrical connection.

[0051] After the relay modules 4 are connected in series, they are secured using the locking assembly 3. Rotating the handle 35 at one end of the lead screw 32 causes the slider 33 to move along the strip-shaped guide opening within the guide housing 31. The pressure plate 34 on top of the slider 33 moves accordingly, gradually abutting against one end of the series-connected relay modules 4. As the lead screw 32 continues to rotate, the pressure plate 34 applies axial pressure to the relay modules 4, firmly pressing and securing them. The soft pad on the outer wall of the pressure plate 34 provides cushioning and anti-slip properties, preventing damage to the outer shell of the relay modules 4 while enhancing the clamping effect.

[0052] Signal transmission process: External audio and video devices (such as cameras, microphones, etc.) are connected through the input port 11 located on the outside of the repeater module 4 near the input end 41. The input port 11 adopts standard interfaces such as HDMI, DP, or RCA to ensure compatibility with various devices. The audio and video signals enter the repeater module 4 through the input end 41, and after being amplified and enhanced internally, they are transmitted to the next repeater module 4 through the output end 42. Multiple repeater modules 4 process the signals in turn, and finally the processed audio and video signals are transmitted to the display device (such as a monitor, projector, etc.) through the output port 12 of the last repeater module 4.

[0053] Power supply process: An external power source is connected through the power port 13 at one end of the casing 1. The power port 13 is connected to the relay module 4 at one end via electrode contacts, forming a power supply path. The power signal is transmitted sequentially to each relay module 4 through the electrode contacts on the series connection block 43 and the connection slot 44, supplying power to the entire repeater system and forming a daisy-chain power supply network to achieve unified power supply.

[0054] Maintenance Process: When equipment maintenance is required or the number of relay modules 4 needs to be adjusted according to new requirements, turn handle 35 to loosen screw 32, so that pressure plate 34 no longer presses down on relay module 4, releasing the fixing effect of locking assembly 3. Then, separate the relay module 4 to be disassembled from the connection between docking block 43 and docking groove 44, completing module disassembly. When installing a new module, repeat the equipment assembly process to achieve quick replacement and adjustment. The entire process requires no complicated tools and is convenient and efficient.

[0055] Finally, it should be noted that the electronic components in the relay module 4 and other components in this embodiment are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.

All of these are technologies known in the art.
