Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle accessory technology, and in particular to an integrated multi-functional signal transfer and composite protective box structure. Background Technology
[0002] Traditional vehicle-mounted signal switching equipment typically has limited functionality or scattered interfaces, making it impossible to achieve centralized switching and reliable electromagnetic protection for multiple signal channels inside and outside the vehicle cabin within a limited installation space, while also meeting the requirements for cabin sealing, lightning protection and interference resistance, and standardized rapid deployment.

[0006] The second housing has a second mounting surface facing the first direction. The second mounting surface is offset from the first mounting surface along the second direction. The second mounting surface is provided with a plurality of external signal interfaces. Each external signal interface is electrically connected to an internal signal interface for electrically connecting to node communication equipment outside the vehicle cabin. The external signal interfaces include at least two of the following: an external Beidou interface, an external camera interface, an external air filtration and ventilation interface, an external perimeter antenna control interface, an external antenna mast control interface, an external nuclear alarm interface, an external nuclear probe interface, and an external shortwave transmitter interface.

[0010] In one embodiment, the integrated multi-functional signal transfer and composite protection box structure further includes a signal electromagnetic pulse protection module. The signal electromagnetic pulse protection module is connected in series on the signal channel between at least one set of corresponding in-vehicle signal interfaces and out-of-vehicle signal interfaces, and is used to suppress electromagnetic pulse interference transmitted from outside the vehicle cabin to inside the vehicle cabin through the out-of-vehicle signal interfaces.
[0011] In one embodiment, the signal electromagnetic pulse protection module includes a first signal electromagnetic pulse protection module, a second signal electromagnetic pulse protection module, a third signal electromagnetic pulse protection module, a fourth signal electromagnetic pulse protection module, and a fifth signal electromagnetic pulse protection module;
[0012] The first signal electromagnetic pulse protection module is connected in series in the signal channel between the in-vehicle Beidou interface and the external Beidou interface;

[0016] The fifth signal electromagnetic pulse protection module is connected in series in the signal channel between the internal nuclear probe interface and the external nuclear probe interface.
[0017] In one embodiment, the integrated multi-functional signal switching and composite protection box structure further includes a feeder electromagnetic pulse (EMIP) protection module. The feeder EMIP protection module is connected in series on the radio frequency feeder channel between the in-vehicle shortwave transmitter interface and the external shortwave transmitter interface, and is used to suppress electromagnetic pulse interference transmitted into the vehicle cabin through the external shortwave transmitter interface.
[0018] In one embodiment, the integrated multi-functional signal transfer and composite protection box structure further includes a feeder surge protector. The feeder surge protector is connected in series on the radio frequency feeder channel between the external shortwave transmitter interface and the feeder electromagnetic pulse protection module. It is used to discharge the lightning surge current introduced through the external shortwave transmitter interface and limit the transient overvoltage on the radio frequency feeder channel.
[0019] In one embodiment, the integrated multi-functional signal transfer and composite protection box structure further includes a grounding component, which is disposed in the first box and / or the second box to release the lightning surge current introduced through the external signal interface and to realize the grounding of the integrated multi-functional signal transfer and composite protection box structure.

[0024] The technical solution of this utility model integrates multiple types of in-vehicle signal interfaces and corresponding external signal interfaces on a first mounting surface and a second mounting surface that are offset along a second direction but facing a first direction, respectively. Signal interconnection between wired channel equipment and node communication equipment inside and outside the vehicle cabin is achieved through internal electrical connections. Specifically, this structure uses a common mounting component to fix the first box to the inside of the vehicle cabin and the second box to the outside, allowing the entire adapter box to be embedded in the vehicle cabin wall in a through-cabin integrated manner. This design integrates multiple signal interfaces, such as those for BeiDou, cameras, filtration and ventilation, antenna control, nuclear and chemical detection, and shortwave communication, which were originally scattered, into a single box structure. This avoids the problems of large space occupation, severe electromagnetic coupling, and sealing difficulties caused by isolated interfaces and messy wiring in traditional equipment. Because the inner and outer enclosures are physically separated yet electrically connected through mounting components, this not only facilitates standardized and rapid installation within limited bulkhead space but also provides a structural foundation for the subsequent integration of electromagnetic pulse (EMP) protection, lightning protection, and grounding modules into the signal channels. This balances the needs for cross-containment sealing, electromagnetic compatibility, lightning surge suppression, and on-site deployment efficiency. Compared to existing technologies with single functions, fragmented interfaces, and a lack of system-level electromagnetic protection, this invention solves the technical challenge of achieving coordinated multi-signal cross-containment switching and reliable electromagnetic protection.

[0032] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[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 scope of protection of the present utility model.
[0034] This utility model proposes an integrated multifunctional signal transfer and composite protection wall box structure 100.
[0035] Please see Figures 1 to 4 In one embodiment of this utility model, the integrated multifunctional signal transfer and composite protection wall box structure 100 includes:
[0036] The first housing 10 has a first mounting surface 11 facing a first direction. The first mounting surface 11 is provided with a plurality of in-vehicle signal interfaces 20 for electrically connecting wired channel equipment in the vehicle cabin. The in-vehicle signal interfaces 20 include at least two of the following: in-vehicle Beidou interface 21, in-vehicle camera interface 22, in-vehicle air filtration and ventilation interface 23, in-vehicle perimeter antenna control interface 24, in-vehicle antenna mast control interface 25, in-vehicle internal alarm interface 26, in-vehicle internal probe interface 27, and in-vehicle shortwave transmitter interface 28.
[0037] The second housing 30 has a second mounting surface 31 facing the first direction. The second mounting surface 31 is offset from the first mounting surface 11 along the second direction. The second mounting surface 31 is provided with a plurality of external signal interfaces 50. Each external signal interface 50 is electrically connected to an internal signal interface 20 for electrically connecting to node communication equipment outside the vehicle cabin. The external signal interface 50 includes at least two of the following: external Beidou interface 51, external camera interface 52, external air filtration and ventilation interface 53, external perimeter antenna control interface 54, external antenna mast control interface 55, external nuclear alarm interface 56, external nuclear probe interface 57, and external shortwave transmitter interface 58.
[0038] Mounting component 40 has a first side 41 and a second side 42 arranged opposite to each other. The first housing 10 is located on the first side 41 and the second housing 30 is located on the second side 42. Mounting component 40 is used to install the integrated multi-functional signal adapter and composite protective wall box structure 100 in the vehicle cabin, such that the first housing 10 is located inside the vehicle cabin and the second housing 30 is located outside the vehicle cabin.
[0039] This utility model discloses an integrated multi-functional signal transfer and composite protective enclosure structure 100 applied to vehicles. The vehicles primarily refer to military vehicles, which need to simultaneously access multiple information systems during missions, including navigation, reconnaissance, communication, NBC (nuclear, biological, chemical) protection, and nuclear / chemical detection. These information systems rely on stable and reliable through-cabin signal channels. The vehicle includes a cabin, which houses the occupants and various onboard equipment. The cabin has a bulkhead, forming a physical barrier between the cabin and the external environment. An onboard signal transfer enclosure is installed on the bulkhead to enable signal interconnection between wired channel equipment within the cabin and external node communication equipment. The integrated multi-functional signal transfer and composite protective enclosure structure 100 is a key interface unit for through-cabin signal transmission; its structural integration and protection capabilities significantly impact signal integrity, electromagnetic compatibility, environmental adaptability, and field deployment efficiency.
[0040] However, traditional vehicle-mounted signal switching equipment is usually single-function or has scattered interfaces. Each signal channel is independently deployed in different locations, which not only occupies a lot of bulkhead space, but also makes it difficult to uniformly implement electromagnetic shielding and sealing treatment. In complex battlefield electromagnetic environment or harsh weather conditions, it is easily interfered with, fails or even damaged. At the same time, on-site installation requires fixing multiple switching devices one by one, resulting in long deployment cycle and great maintenance difficulty.
[0041] To address this challenge, the integrated multi-functional signal transfer and composite protection enclosure structure 100 proposed in this utility model includes a first enclosure 10 and a second enclosure 30. The first enclosure 10 has a first mounting surface 11 facing a first direction, on which multiple in-vehicle signal interfaces 20 are provided for electrically connecting wired channel equipment in the vehicle cabin. The multiple in-vehicle signal interfaces 20 may include at least two of the following: an in-vehicle Beidou interface 21, an in-vehicle camera interface 22, an in-vehicle air filtration and ventilation interface 23, an in-vehicle perimeter antenna control interface 24, an in-vehicle antenna mast control interface 25, an in-vehicle internal alarm interface 26, an in-vehicle internal probe interface 27, and an in-vehicle shortwave transmitter interface 28. For example, the multiple in-vehicle signal interfaces 20 may only include the in-vehicle Beidou interface 21 and the in-vehicle camera interface 22, or only include the in-vehicle Beidou interface 21 and the in-vehicle air filtration and ventilation interface 23, etc. Other pairwise combinations are similar and will not be listed here. Similarly, other combinations of quantities are also similar and will not be listed here.
[0042] The first housing 10 serves as a signal gathering unit inside the vehicle cabin. Multiple in-vehicle signal interfaces 20 integrated on its first mounting surface 11 correspond to different types of in-vehicle mission systems. For example, the in-vehicle Beidou interface 21 is used to connect to the in-vehicle Beidou navigation terminal to receive positioning and timing signals; the in-vehicle camera interface 22 is used to connect to the in-vehicle camera equipment to transmit video signals; the in-vehicle filtration and ventilation interface 23 is used to connect to the in-vehicle NBC protection control system to transmit filtrate ventilation control signals; the in-vehicle peripheral antenna control interface 24 and the in-vehicle antenna mast control interface 25 are used to connect to the in-vehicle antenna control device to realize remote operation of the peripheral antenna or the raising and lowering antenna mast; the in-vehicle nuclear alarm interface 26 and the in-vehicle nuclear probe interface 27 are used to connect to the in-vehicle nuclear, chemical and biological detection equipment to receive alarm signals or environmental monitoring signals; and the in-vehicle shortwave transmitter interface 28 is used to connect to the in-vehicle shortwave communication transmitter to output radio frequency signals.
[0043] The second housing 30 has a second mounting surface 31 facing the first direction. The second mounting surface 31 is offset from the first mounting surface 11 along the second direction. The second mounting surface 31 is provided with multiple external signal interfaces 50. Each external signal interface 50 is electrically connected to an internal signal interface 20 for electrically connecting to node communication equipment outside the vehicle cabin. The multiple external signal interfaces 50 may include at least two of the following: an external Beidou interface 51, an external camera interface 52, an external air filtration and ventilation interface 53, an external perimeter antenna control interface 54, an external antenna mast control interface 55, an external nuclear alarm interface 56, an external nuclear probe interface 57, and an external shortwave transmitter interface 58. For example, when multiple in-vehicle signal interfaces 20 include an in-vehicle BeiDou interface 21 and an in-vehicle camera interface 22, multiple external signal interfaces 50 may include an external BeiDou interface 51 and an external camera interface 52. The external BeiDou interface 51 is electrically connected to the in-vehicle BeiDou interface 21, and the external camera interface 52 is electrically connected to the in-vehicle camera interface 22. Alternatively, when multiple in-vehicle signal interfaces 20 include an in-vehicle BeiDou interface 21 and an in-vehicle air filtration and ventilation interface 23, multiple external signal interfaces 50 may include an external BeiDou interface 51 and an external air filtration and ventilation interface 53. The external BeiDou interface 51 is electrically connected to the in-vehicle BeiDou interface 21, and the external air filtration and ventilation interface 53 is electrically connected to the in-vehicle air filtration and ventilation interface 23. Other pairwise combinations are similar and will not be listed here. Similarly, other combinations of quantities are also similar and will not be listed here.
[0044] The second enclosure 30 serves as a signal output unit on the outside of the vehicle cabin. Multiple external signal interfaces 50 integrated on its second mounting surface 31 correspond to different types of external devices. For example, the external Beidou interface 51 is used to connect to the external Beidou navigation antenna to introduce positioning and timing signals; the external camera interface 52 is used to connect to the external camera pan-tilt unit to transmit video signals; the external filtration and ventilation interface 53 is used to connect to the external filtration and ventilation system to transmit filtrate ventilation control signals; the external peripheral antenna control interface 54 is used to connect to the external antenna control device to realize remote operation of the external peripheral antenna pointing; the external nuclear and chemical alarm interface 56 and the external nuclear and chemical probe interface 57 are used to connect to the external nuclear, chemical and biological detection equipment to receive alarm signals or environmental monitoring signals; and the external shortwave transmitter interface 58 is used to connect to the external shortwave communication antenna to output radio frequency signals.
[0045] To facilitate the assembly of the first enclosure 10 and the second enclosure 30 in the vehicle cabin, the integrated multi-functional signal adapter and composite protective enclosure structure 100 also includes a mounting component 40. The mounting component 40 has a first side 41 and a second side 42 arranged opposite to each other. The first enclosure 10 is located on the first side 41, and the second enclosure 30 is located on the second side 42. The mounting component 40 is used to install the integrated multi-functional signal adapter and composite protective enclosure structure 100 in the vehicle cabin, such that the first enclosure 10 is located inside the vehicle cabin, and the second enclosure 30 is located outside the vehicle cabin. By centrally arranging multiple signal interfaces on the inner and outer sides of the same enclosure and using the mounting component 40 to achieve integrated installation through the vehicle cabin, the problems of wiring chaos, interface redundancy, and space waste caused by traditional distributed adapter methods can be avoided.
[0046] Specifically, since both the first mounting surface 11 and the second mounting surface 31 are oriented towards the first direction, and the first mounting surface 11 and the second mounting surface 31 are staggered along the second direction (i.e., the first mounting surface 11 and the second mounting surface 31 are oriented towards and close to the bottom of the vehicle compartment), this arrangement allows operators to identify, plug, unplug, or maintain the interfaces on their respective sides from an upward-looking posture, whether inside or outside the vehicle compartment, without having to go around to the top of the vehicle compartment, thus improving the convenience of human-machine operation. At the same time, this staggered layout physically separates the interface areas inside and outside the vehicle compartment, avoiding the crossing and tangling of internal and external cables at the interfaces, reducing the risk of poor contact and mechanical damage caused by cable bending or pulling. In addition, since the first mounting surface 11 and the second mounting surface 31 maintain a certain distance in the second direction, sufficient structural thickness space can be reserved at the bulkhead mounting opening, facilitating the installation of sealing or electromagnetic shielding components between the mounting component 40 and the bulkhead, thereby ensuring environmental sealing and electromagnetic continuity at the penetration point without increasing the overall outline dimensions.
[0047] The technical solution of this utility model integrates multiple types of in-vehicle signal interfaces 20 and corresponding external signal interfaces 50 on a first mounting surface 11 and a second mounting surface 31, which are respectively oriented in the first direction but offset along the second direction. Signal interconnection between wired channel equipment and node communication equipment inside and outside the vehicle cabin is achieved through internal electrical connections. Specifically, this structure uses a common mounting component 40 to fix the first housing 10 to the inside of the vehicle cabin and the second housing 30 to the outside of the vehicle cabin, allowing the entire adapter box to be embedded in the vehicle cabin wall in a through-cabin integrated form. This design integrates multiple signal interfaces, such as those for BeiDou, cameras, filtration and ventilation, antenna control, nuclear and chemical detection, and shortwave communication, which were originally scattered, into a single box structure. This avoids the problems of large space occupation, severe electromagnetic coupling, and sealing difficulties caused by isolated interfaces and messy wiring in traditional equipment. Because the inner and outer enclosures are physically separated yet electrically connected through the mounting component 40, this not only facilitates standardized and rapid installation within limited bulkhead space but also provides a structural foundation for the subsequent integration of electromagnetic pulse (EMP) protection, lightning protection, and grounding modules into the signal channels. This balances the needs for cross-containment sealing, electromagnetic compatibility, lightning surge suppression, and on-site deployment efficiency. Compared to existing technologies with single functions, fragmented interfaces, and a lack of system-level electromagnetic protection, this invention solves the technical challenge of achieving coordinated multi-signal cross-containment switching and reliable electromagnetic protection.
[0048] like Figures 1 to 4 As shown, in one embodiment, the in-vehicle signal interface 20 includes an in-vehicle Beidou interface 21, an in-vehicle camera interface 22, an in-vehicle air filtration and ventilation interface 23, an in-vehicle perimeter antenna control interface 24, an in-vehicle antenna mast control interface 25, an in-vehicle internal alarm interface 26, an in-vehicle internal probe interface 27, and an in-vehicle shortwave transmitter interface 28 arranged in multiple rows along the second direction.
[0049] In this embodiment, the aforementioned multiple in-vehicle signal interfaces 20 are arranged in rows along the second direction on the first mounting surface 11 according to their functional categories and usage frequencies, forming an orderly in-vehicle interface array. By arranging the in-vehicle signal interfaces 20 with different functions in multiple rows along the second direction, not only can the interface density per unit area be increased, making it easier to accommodate more in-vehicle signal interfaces 20 on the limited first mounting surface 11, but also the similar or related interfaces are arranged close together in space, which is beneficial for cable classification and routing, reducing cross interference, and making it easier for operators to quickly identify and plug in and unplug corresponding interfaces, thereby improving maintenance efficiency and reliability.
[0050] like Figures 1 to 4As shown, in one embodiment, the external signal interface 50 includes multiple rows of external Beidou interfaces 51, external camera interfaces 52, external air filtration and ventilation interfaces 53, external perimeter antenna control interfaces 54, external antenna mast control interfaces 55, external nuclear alarm interfaces 56, external nuclear probe interfaces 57, and external shortwave transmitter interfaces 58 arranged along the second direction.
[0051] In this embodiment, the aforementioned multiple external signal interfaces 50 are arranged in rows along the second direction on the second mounting surface 31 according to the functional attributes and physical connection requirements of their corresponding external devices, forming an orderly array of external interfaces. By arranging the external signal interfaces 50 with different functions in multiple rows along the second direction, not only can the space utilization efficiency of the second mounting surface 31 be improved, making it easier to accommodate more external signal interfaces 50 in a limited area, but also interfaces with related functions or similar wiring paths are kept close in physical location, which helps to reduce the cross-entanglement and electromagnetic coupling of external cables, while facilitating quick identification, plugging and maintenance on site.
[0052] like Figures 1 to 4 As shown, in one embodiment, the integrated multi-functional signal transfer and composite protection box structure 100 further includes a signal electromagnetic pulse protection module 60. The signal electromagnetic pulse protection module 60 is connected in series on the signal channel between at least one set of corresponding in-vehicle signal interfaces 20 and external signal interfaces 50, and is used to suppress electromagnetic pulse interference transmitted from outside the vehicle cabin to inside the vehicle cabin through the external signal interface 50.
[0053] In this embodiment, the signal electromagnetic pulse (EMP) protection module 60, as a key component of electromagnetic protection, is integrated into the internal electrical connection path between the first housing 10 and the second housing 30. Its input terminal is electrically connected to the external signal interface 50, and its output terminal is electrically connected to the corresponding internal signal interface 20, thereby filtering or clamping all external interference energy flowing through the signal channel. When the external signal interface 50 couples transient high-energy signals due to lightning, nuclear EMP, or high-intensity radio frequency interference, the signal EMP protection module 60 can respond quickly, limiting overvoltage or overcurrent within a safe threshold to prevent damage or malfunction of sensitive in-vehicle wired channel equipment. Since different signal types have different sensitivities and transmission characteristics to EMP, this module can select appropriate filters, transient suppression diodes, gas discharge tubes, or composite protection circuits according to the specific requirements of the protected channel to ensure effective suppression without affecting normal signal transmission. By directly embedding the signal electromagnetic pulse (EMP) protection module 60 into the signal channel inside the enclosure, the extra wiring length and parasitic inductance caused by external protective devices can be avoided, improving the protection response speed and overall shielding effectiveness. This design enables the integrated multi-functional signal switching and composite protection enclosure structure 100 to not only perform signal switching functions but also possess built-in EMP protection capabilities, providing structured assurance for the communication reliability and system survivability of military vehicles in complex electromagnetic battlefield environments.
[0054] like Figures 1 to 4 As shown, in one embodiment, the signal electromagnetic pulse protection module 60 includes a first signal electromagnetic pulse protection module 61, a second signal electromagnetic pulse protection module 62, a third signal electromagnetic pulse protection module 63, a fourth signal electromagnetic pulse protection module 64, and a fifth signal electromagnetic pulse protection module 65.
[0055] The first signal electromagnetic pulse protection module 61 is connected in series in the signal channel between the in-vehicle Beidou interface 21 and the external Beidou interface 51.
[0056] The second signal electromagnetic pulse protection module 62 is connected in series on the signal channel between the in-vehicle camera interface 22 and the external camera interface 52;
[0057] The third signal electromagnetic pulse protection module 63 is connected in series in the signal channel between the in-vehicle air filter ventilation interface 23 and the out-of-vehicle air filter ventilation interface 53.
[0058] The fourth signal electromagnetic pulse protection module 64 is connected in series on the signal channel between the in-vehicle nuclear alarm interface 26 and the external nuclear alarm interface 56;
[0059] The fifth signal electromagnetic pulse protection module 65 is connected in series in the signal channel between the internal nuclear probe interface 27 and the external nuclear probe interface 57.
[0060] In this embodiment, the five signal electromagnetic pulse protection modules 60 are configured independently for signal channels of different functional types to adapt to the electrical characteristics and protection requirements of each channel. The first electromagnetic pulse (EMP) protection module 61 protects the signal channel between the Beidou navigation terminal inside the vehicle and the Beidou navigation antenna outside the vehicle, suppressing external electromagnetic pulses from interfering with positioning and timing signals, and ensuring the continuous availability of the Beidou navigation terminal and antenna in strong electromagnetic environments. The second EMP protection module 62 protects the signal channel between the camera equipment inside the vehicle and the camera pan-tilt unit outside the vehicle, preventing image distortion or communication interruption caused by transient interference. The third EMP protection module 63 acts on the signal channel between the NBC protection control system inside the vehicle and the NBC filtration and ventilation system outside the vehicle, ensuring that the control signals of the NBC filtration and ventilation system can still be reliably transmitted under harsh conditions. The fourth and fifth EMP protection modules 64 and 65 are respectively deployed in the signal channels of the nuclear and chemical alarm and the nuclear and chemical probe, used to block the impact of external high-energy interference on the false triggering or signal distortion of nuclear, chemical, and biological detection equipment, and improve the accuracy and timeliness of nuclear and chemical threat perception in battlefield environments.
[0061] By connecting each module in series between a corresponding set of in-vehicle signal interfaces 20 and external signal interfaces 50, a point-to-point protection path is formed. This avoids inter-channel coupling that may be caused by sharing protection circuits and allows for customization of filtering parameters and clamping thresholds based on the bandwidth, level, and protocol characteristics of each type of signal. This channel-specific, modular protection architecture enables the integrated multi-functional signal transfer and composite protection box structure 100 to achieve centralized transfer of multiple signals while possessing refined and highly matched electromagnetic pulse suppression capabilities, effectively supporting the stable operation of military vehicle-mounted information systems in complex electromagnetic battlefields.
[0062] like Figures 1 to 4 As shown, in one embodiment, the integrated multi-functional signal switching and composite protection box structure 100 further includes a feeder electromagnetic pulse protection module 70. The feeder electromagnetic pulse protection module 70 is connected in series on the radio frequency feeder channel between the in-vehicle shortwave transmitter interface 28 and the external shortwave transmitter interface 58, and is used to suppress electromagnetic pulse interference transmitted into the vehicle cabin through the external shortwave transmitter interface 58.
[0063] In this embodiment, the feeder electromagnetic pulse (EMP) protection module 70 is installed in the radio frequency (RF) feeder channel connecting the in-vehicle shortwave transmitter interface 28 and the external shortwave transmitter interface 58. This RF feeder channel is used to transmit the RF signal output by the in-vehicle shortwave transmitter to the external shortwave antenna. Since the external shortwave transmitter interface 58 is directly connected to the external shortwave communication antenna, it is susceptible to lightning, nuclear electromagnetic pulses, or high-intensity RF interference, which may couple high-energy transient signals into the feeder. The feeder EMP protection module 70, connected in series to this RF feeder channel, effectively suppresses electromagnetic pulse interference introduced from the external shortwave transmitter interface 58 without affecting normal RF signal transmission, preventing it from entering the vehicle cabin and causing interference or damage to in-vehicle equipment. By integrating the feeder electromagnetic pulse protection module 70 into the integrated multi-functional signal converter and composite protection box structure 100, embedded electromagnetic protection can be achieved for the radio frequency feeder channel between the in-vehicle shortwave transmitter interface 28 and the external shortwave transmitter interface 58, avoiding the wiring complexity and interface reliability problems caused by external protection devices, thereby improving the vehicle's operational stability in complex electromagnetic environments.
[0064] like Figures 1 to 4 As shown, in one embodiment, the integrated multi-functional signal transfer and composite protection box structure 100 also includes a feeder surge protector 80. The feeder surge protector 80 is connected in series on the radio frequency feeder channel between the external shortwave transmitter interface 58 and the feeder electromagnetic pulse protection module 70, and is used to discharge the lightning surge current introduced through the external shortwave transmitter interface 58 and limit the transient overvoltage on the radio frequency feeder channel.
[0065] In this embodiment, the feeder surge protector 80 is positioned in the RF feeder channel between the external shortwave transmitter interface 58 and the feeder electromagnetic pulse (EMP) protection module 70. This allows for surge protection while meeting signal transmission rate, insertion loss, and bandwidth requirements. When the external shortwave transmitter interface 58 senses a lightning surge due to its connection to an external shortwave communication antenna, the high-amplitude surge current first flows through the feeder surge protector 80, which quickly conducts and discharges it to ground, significantly reducing the energy entering subsequent circuits. Simultaneously, the feeder surge protector 80 clamps transient overvoltages on the RF feeder channel to a safe level, preventing impact or damage to the feeder EMP protection module 70 and the in-vehicle shortwave transmitting equipment. This positioning allows the feeder surge protector 80 to prioritize handling high-energy lightning surges, while the feeder EMP protection module 70 focuses on suppressing residual high-frequency electromagnetic pulse interference, forming a hierarchical and coordinated protection mechanism. Since the feeder surge protector 80 is integrated within the integrated multi-functional signal converter and composite protection box structure 100, its grounding path can be directly connected to the box's grounding structure, ensuring a low-impedance, short, and direct discharge channel, thus improving lightning response efficiency. This design enhances the RF feeder channel's resistance to high-energy transient events such as lightning without altering the original RF signal transmission function, thereby improving the reliability and safety of the entire integrated multi-functional signal converter and composite protection box structure 100 under outdoor or harsh weather conditions.
[0066] like Figures 1 to 4 As shown, in one embodiment, the integrated multi-functional signal transfer and composite protection box structure 100 further includes a grounding component, which is disposed in the first box 10 and / or the second box 30, for releasing the lightning surge current introduced through the external signal interface 50 and realizing the grounding of the integrated multi-functional signal transfer and composite protection box structure 100.
[0067] In this embodiment, the grounding component is fixed to the first enclosure 10 and / or the second enclosure 30, providing a low-impedance discharge path for lightning surge currents. When lightning couples into the integrated multi-functional signal transfer and composite protection box structure 100 through the external signal interface 50, especially high-energy surges introduced through the external shortwave transmitter interface 58, it can be guided to the grounding component by the feeder surge protector 80 and quickly released to the vehicle ground or the earth, preventing energy accumulation inside and causing equipment damage. Simultaneously, the grounding component also serves to achieve overall equipment safety grounding of the integrated multi-functional signal transfer and composite protection box structure 100, ensuring the electrical safety of operators and connected equipment. To ensure protection effectiveness, an equipotential connection is formed between the grounding terminal of the feeder surge protector 80, the first enclosure 10 and / or the second enclosure 30, and the grounding component. The connection paths between all grounding parts are designed to be short and straight to reduce grounding loop inductance and impedance, and improve transient current discharge efficiency. This integrated grounding layout not only enhances the electromagnetic compatibility performance of the integrated multi-functional signal transfer and composite protective box structure 100, but also improves the operational reliability of vehicles in complex battlefield or field environments.
[0068] like Figures 1 to 4 As shown, in one embodiment, the first housing 10 and / or the second housing 30 are provided with a square flange mounting structure, the grounding component is fixed to the square flange mounting structure, the square flange mounting structure is provided with fasteners for connecting the grounding wire and preventing the grounding component from rotating or being damaged during the tightening of the grounding wire.
[0069] In this embodiment, a square flange mounting structure serves as the mounting base for the grounding component, and is mounted on the first housing 10 and / or the second housing 30. Its square shape provides torsional restraint. This structure securely fixes the grounding component, preventing rotation or loosening when torque is applied to tighten the grounding wire using tools. The square flange mounting structure is equipped with fasteners, specifically M12 grounding bolts, for connecting the external grounding wire. Because the square flange mounting structure is rigidly connected to the housing, and its square outline restricts circumferential displacement, when the M12 grounding bolt is tightened, the reaction force is borne by the entire square flange mounting structure, rather than solely by the grounding component, effectively preventing rotation, deformation, or damage to the grounding component due to stress.
[0070] like Figures 1 to 4 As shown, in one embodiment, the grounding element is made of copper.
[0071] In this embodiment, the grounding component is made of copper, which has excellent conductivity and low resistivity, facilitating the rapid discharge of lightning surge currents. It also possesses good corrosion resistance and machinability, enabling it to maintain a stable electrical connection in a vehicle-mounted environment over a long period. Since the grounding component needs to form an equipotential connection with the feeder surge protector 80, the first enclosure 10, and / or the second enclosure 30, and reliably connect to the external grounding wire via a square flange mounting structure, the use of copper helps reduce the overall grounding circuit impedance, improving transient overvoltage suppression and system safety. Furthermore, the ductility of copper makes it less prone to cracking or brittle fracture during fastening. When used with M12 grounding bolts, it ensures reliable contact pressure and conductivity even under repeated disassembly and vibration conditions, thereby guaranteeing the grounding reliability and electromagnetic protection effectiveness of the integrated multi-functional signal transfer and composite protective enclosure structure 100 in complex battlefield or field environments.
[0072] like Figures 1 to 4 As shown, in one embodiment, the volume of the first box 10 is greater than the volume of the second box 30.
[0073] In this embodiment, the first enclosure 10, located inside the vehicle cabin, needs to accommodate multiple in-vehicle signal interfaces 20 and their corresponding internal wiring space. It may also integrate protective components such as a signal electromagnetic pulse protection module 60. Therefore, a larger volume is used to meet the requirements of wiring, heat dissipation, and module installation. The second enclosure 30, located outside the vehicle cabin, mainly handles the arrangement and external connection of the external signal interfaces 50. Its internal structure is relatively simple, requiring fewer components, hence its smaller volume. The first enclosure 10 and the second enclosure 30 are connected by mounting brackets 40 and are respectively located inside and outside the vehicle cabin. The difference in their volumes balances the high integration and frequent operation and maintenance of the equipment inside the vehicle cabin, as well as the requirements for structural compactness or protective shape outside the vehicle cabin. This volume configuration helps optimize the overall installation layout of the enclosure on the cabin wall, ensuring functional integrity while avoiding excessive protrusion of the external parts that could affect vehicle passage or concealment.
[0074] like Figures 1 to 4 As shown, in one embodiment, the first box 10 includes a box body 12 and a cover plate 13. The box body 12 has an opening 101, and the cover plate 13 is detachably disposed on the opening 101.
[0075] In this embodiment, the enclosure body 12 serves as the main structure of the first enclosure 10, with an opening 101 on one side to provide access to the internal space. The cover plate 13 is detachably fixed to the opening 101 by fasteners, thereby closing the first enclosure 10. Since the first enclosure 10 is located inside the vehicle cabin, operators can directly access the cover plate 13 from inside the cabin without disassembling the entire enclosure or entering the outside. When it is necessary to check the internal cable connections, replace the signal electromagnetic pulse protection module 60, or troubleshoot, simply remove the fasteners securing the cover plate 13 to remove it, exposing the interface wiring, feeder paths, and protective devices inside the enclosure. This design facilitates daily maintenance, rapid repair, and functional upgrades, while maintaining the structural integrity and electromagnetic shielding continuity of the first enclosure 10 even after the cover plate 13 is reset.
[0076] This utility model discloses an integrated multi-functional signal adapter and composite protective enclosure structure 100 applied to a vehicle. The vehicle includes a cabin and the integrated multi-functional signal adapter and composite protective enclosure structure 100. The integrated multi-functional signal adapter and composite protective enclosure structure 100 is fixed to the mounting opening in the cabin via a mounting member 40. An electromagnetic shielding member, consisting of a 120-mesh copper mesh or a serrated copper strip, is placed between the mating surfaces of the mounting opening and the mounting member 40. During assembly, after placing the electromagnetic shielding member on the contact surface between the mounting opening and the mounting member 40, all stainless steel mounting screws on the mounting member 40 are tightened to ensure a tight seal between the mounting member 40 and the cabin. This ensures that the electromagnetic shielding member forms a continuous, low-impedance conductive path at the interface, suppressing external electromagnetic interference from coupling into the cabin through the mounting gaps, and preventing signals from inside the vehicle from leaking to the external environment. Tests have shown that this connection method can achieve an electromagnetic shielding effectiveness of no less than 60 dB in the frequency range of 100 kHz to 10 GHz, meeting the requirements of military vehicles for high electromagnetic compatibility and ensuring the normal operation of the vehicle-mounted information system in complex electromagnetic battlefield environments.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
