Description

Technical Field

[0001] This invention belongs to the field of automobile manufacturing technology, and more specifically, relates to an electromagnetic shielding system and implementation method for armored protective special vehicles. Background Technology

[0002] With the evolution of modern warfare, informatization and electronification have become key characteristics. Special vehicles, as crucial equipment in modern high-tech warfare, face severe electromagnetic environment challenges in their electronic systems. In complex battlefield environments, special vehicles must not only withstand traditional firepower but also effectively protect their electronic information systems from electromagnetic threats such as electromagnetic pulses (EMPs). Traditional armored vehicles primarily focus on physical protection, neglecting the importance of electromagnetic protection. With the development of electronic and cyber warfare, the electromagnetic compatibility issues of special vehicles are becoming increasingly prominent. Electronic equipment inside vehicles is susceptible to interference in complex electromagnetic environments, affecting vehicle mobility and safety. Windows, equipment openings, and cables are the main pathways for electromagnetic interference, while existing shielding technologies often suffer from problems such as heavy weight, high cost, and complex installation. Armored protective special vehicles are widely used across various branches of the armed forces due to their superior protection capabilities, high strength, high mobility, and exceptional environmental adaptability and reliability. The armored protective special vehicle described here is a light, highly mobile armored vehicle with strong load-bearing capacity and modification potential. It serves as a crucial platform for logistical support and information warfare, and has seen successful applications in artillery and radar mounting. Currently, as a radar mounting platform, the electromagnetic waves emitted during radar operation can penetrate the vehicle body, causing electromagnetic damage to the operators. Therefore, armored protective special vehicles serving as radar mounting platforms urgently need to achieve a certain level of electromagnetic shielding to reduce electromagnetic radiation damage and protect the onboard personnel.

[0003] Existing technologies typically employ electromagnetic shielding methods, such as installing windows or doors with electromagnetic shielding capabilities, to achieve overall vehicle electromagnetic shielding. However, this approach fails to meet the shielding requirements for high-intensity electromagnetic fields, particularly in complex or rapidly changing electromagnetic environments. Furthermore, the shielding design of windows or doors is not compatible with the shielding measures of other parts of the vehicle, potentially creating pathways for electromagnetic leakage and affecting the final shielding effectiveness.

[0004] As a platform for radar transmission, armored protective special vehicles are located very close to radar transmitters. Strong electromagnetic waves can penetrate the vehicle body and harm the health of the operators. The existing vehicle structure is insufficient to meet electromagnetic shielding requirements. Targeted design and manufacturing processes are needed based on the vehicle's performance to create a conductive structure throughout the crew compartment, thereby meeting the 30dB electromagnetic shielding requirement for the crew compartment in the 300MHz-18.5GHz range. Summary of the Invention

[0005] To address the aforementioned deficiencies or improvement needs of existing technologies, this invention provides an electromagnetic shielding system for armored protective special vehicles. By applying a conductive coating material to the connection points between the body-in-white and the protective glass, doors, and related components, an effective conductive connection is formed between the protective glass, doors, and related components and the entire vehicle body. This creates a continuous conductor throughout the passenger compartment, forming a continuous equipotential body in the shielding layer. This achieves the absorption and reflection of electromagnetic wave energy, thus achieving the purpose of shielding electromagnetic waves.

[0006] This invention provides an electromagnetic shielding system for armored protective special vehicles. The armored protective special vehicle includes a pre-welded body-in-white. The electromagnetic shielding system includes a body-coated conductive connection component and a body accessory shielding component. The body accessory shielding component includes protective glass and protective doors. The body-coated conductive connection component includes a conductive coating material disposed close to the conductive connection area of ​​the body-in-white. The conductive coating material is disposed 10-30mm from the outer periphery of the body accessory shielding component, forming a conductive path. The body-coated conductive connection component connects the body-in-white and the body accessory shielding component to form a continuous conductor, forming a continuous equipotential body in the shielding layer to absorb and reflect electromagnetic wave energy.

[0007] Furthermore, the protective glass includes an electromagnetic shielding film with conductive properties disposed inside it. The electromagnetic shielding film is in communication with the metal frame for mounting the protective glass to form an electromagnetic shielding layer. The metal frame for mounting the protective glass is connected to the body-in-white by bolts.

[0008] Furthermore, a conductive rubber pad is added between the protective glass mounting metal frame and the mounting base, so that the three are effectively connected.

[0009] Furthermore, a conductive coating material is sprayed onto the outer perimeter of the connection position between the protective glass mounting metal frame and the mounting base, leaving a 10-30mm space.

[0010] Furthermore, the protective glass includes a sliding glass and a metal frame connected to the sliding glass via a sliding rail structure, and is provided on the vehicle door and the side of the vehicle body. A sliding rail conductive sealing strip is provided between the sliding glass and the metal frame. One end of the sliding rail conductive sealing strip is connected to the sliding glass, and the other end is connected to the metal frame to form a conductive branch.

[0011] Furthermore, a conductive coating material is sprayed onto the sheet metal perimeter of the door conductive sealing strip located between the protective door and the vehicle body door frame, leaving a 10-30mm gap. When the door is closed, the conductive coating material at the reserved position is in close contact with the door conductive sealing strip, and the door and the vehicle body are effectively connected.

[0012] Furthermore, the vehicle body accessory shielding assembly also includes a vent mounting plate and a component mounting surface. A conductive coating material is applied to a 10-30mm space around the outer periphery of the vehicle body component, thus forming effective conductivity between the vehicle body component and the vehicle body structure.

[0013] Furthermore, the vent includes air conditioning vents, vehicle body vents, etc. A waveguide plate is installed at the vent location, and the waveguide plate is connected to the conductive coating material at a reserved position on the outer periphery of the vent to form a conductive structure.

[0014] Furthermore, the vehicle body accessory shielding assembly also includes functional components such as wiring harnesses, pipes, and steering columns that are installed through the vehicle compartment. The sealing gaskets used during component installation are replaced with conductive sealing rings. Conductive adhesive is applied between the conductive sealing rings and the conductive coating material at the reserved position on the outer periphery of the component, so that the component and the vehicle body can form effective conductivity.

[0015] This invention also provides a method for implementing an electromagnetic shielding system for armored protective special vehicles, comprising the following steps:

[0016] S100: Body Treatment: First, the body-in-white is manufactured by cutting, bending, stamping and welding steel plates for the structural components required by the body-in-white. The connection positions between the body-in-white and the protective glass, windshield, protective doors and related parts are determined. After process planning, 10-30mm wide electrophoretic corrosion-resistant special tape is pasted on the areas that need to be conductive. Then, electrophoretic coating is applied to the body-in-white with local protection. After coating, it is cleaned and dried, and the corrosion-resistant tape is removed, forming a 10-30mm wide uncoated strip after the whole vehicle is electrophoretically coated.

[0017] S200: Conductive coating application: Conductive paint is sprayed onto uncoated areas for corrosion resistance treatment, forming conductive paths. These areas include the perimeter of doors, the perimeter of protective glass installation, the perimeter of vents, and the perimeter of related components. After painting, the body-in-white enters the final assembly workshop for assembly, thus forming an armored special vehicle.

[0018] S300: Front windshield assembly: The windshield protective glass with embedded electromagnetic shielding film is fixedly installed in the windshield protective glass mounting metal frame to form the front windshield. The windshield and the protective structure of the body are connected by bolts. The windshield and the body-in-white are connected. A conductive rubber gasket for the windshield is added between the two to improve the rain sealing ability.

[0019] S400: Assembly of protective doors: The protective glass of the door with embedded electromagnetic shielding film is fixedly installed in the metal frame of the door glass to form a protective sliding window. The protective sliding window is connected to the metal frame with sliding window rails through a sliding rail structure. The protective sliding window and the metal frame with sliding window rails are conductive to form a protective glass window. The protective glass window is connected to the door protective steel plate by bolts. A conductive rubber pad for the door and window is added between the metal frame with sliding window rails and the protective door to improve the rain sealing ability.

[0020] S500: Door-to-Body Connection: A conductive sealing strip is embedded in the edge of the body sheet metal, with an uncoated strip left, coated with conductive paint, and connected to the side protective steel plate. The door sheet metal is welded to the door protective steel plate, with an uncoated strip left, coated with conductive paint, and the two make conductive contact. The door hinges are connected to the body-in-white to achieve opening and closing. When the door is closed, it is in close contact with the body sheet metal, forming a conductive connection. A door sealing strip is installed, which, when the protective door is closed, is tightly pressed against the body sheet metal, forming a double-seal structure.

[0021] S600: Assembly of the front body: The front body is welded together with the front windshield, side panels, rear body and other structures to form the body-in-white. Through holes are added at the installation positions of chassis parts, conductive paint is sprayed, and conductive pads are added during installation to promote the formation of a conductive structure between the front body and the parts.

[0022] S700: Treatment of vent holes and through-cabin components: Install waveguide plates at the vent hole positions and connect them to the uncoated strip positions to form a conductive structure. Apply conductive paint to the uncoated strip around the installation perimeter of through-cabin components. Replace the gaskets during the installation of functional components with conductive sealing rings. Apply conductive adhesive between the conductive sealing rings and the conductive paint.

[0023] S800: Overall Connection: All components are assembled onto the white body to complete the final assembly of the armored special vehicle. Through the above measures, the doors, windows, ventilation holes and penetration components are all electrically connected to the body through conductive rubber, conductive paint and conductive sealing strips, so that the conductive materials of the entire crew compartment are interconnected to form a continuous conductor.

[0024] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects:

[0025] 1. The electromagnetic shielding system for armored protective special vehicles provided by this invention forms an effectively conductive body-in-white by shielding the contact areas of the body-in-white and its auxiliary mounting components. Furthermore, a 10-30mm uncoated strip is left between the body-in-white and the auxiliary mounting components, and conductive coating material is sprayed onto this uncoated strip, ensuring close contact between the conductive material and the body. This creates a continuous equipotential body that absorbs and reflects electromagnetic waves from the target area, achieving electromagnetic shielding within the target range. This system meets the electromagnetic shielding requirement of 30dB in the 300MHz-18.5GHz frequency range, ensuring the normal operation of electronic equipment and personnel safety within the vehicle.

[0026] 2. The electromagnetic shielding system for armored protective special vehicles provided by this invention effectively blocks electromagnetic waves from penetrating by embedding electromagnetic shielding films in key parts such as the windshield and protective doors, and connecting them to the metal frame, thus protecting the personnel and equipment inside the vehicle from electromagnetic radiation damage.

[0027] 3. The electromagnetic shielding system for armored protective special vehicles provided by this invention not only provides electromagnetic shielding by adding conductive rubber pads and door / window conductive rubber pads at the connection points of the windshield and protective doors, but also enhances the sealing of the structure and improves the vehicle's performance under adverse weather conditions.

[0041] The following is in conjunction with the appendix to this instruction manual. Figure 1 The preferred embodiments of this disclosure will be further described in detail below.

[0042] Please see Figure 1 , Figure 2 and Figure 3 The present invention relates to an electromagnetic shielding system for armored protective special vehicles, comprising a vehicle body coating conductive connection component and a vehicle body accessory shielding component. The vehicle body accessory shielding component includes protective glass and protective doors. The vehicle body coating conductive connection component includes a conductive coating material disposed in close contact with the conductive connection area of ​​the white body 100. The conductive coating material is disposed around the vehicle body accessory shielding component to form a conductive path. The vehicle body coating conductive connection component connects the vehicle body and the vehicle body accessory shielding component to form a continuous conductor, forming a continuous equipotential body in the shielding layer to absorb and reflect electromagnetic wave energy.

[0043] Preferably, the conductive coating material is a conductive paint, such as a doped conductive paint, a metal-based conductive paint, or a graphite conductive paint.

[0044] The protective glass includes an electromagnetic shielding film with conductive properties disposed inside it. The electromagnetic shielding film is in communication with the metal frame on which the protective glass is mounted, forming an electromagnetic shielding layer. The metal frame on which the protective glass is mounted is connected to the vehicle body by bolts.

[0045] like Figure 4 As shown, the windshield 200 is formed by embedding the windshield electromagnetic shielding protective glass 202 into the windshield protective glass mounting metal frame 201. The protective glass window is connected to the protective glass window profile structure composed of the windshield protective steel plate 101, the first windshield sheet metal 102, and the second windshield sheet metal 103 on the vehicle body by bolts. A windshield conductive rubber pad 203 is added in the middle of the connection between the two to form the windshield 200. The windshield protective steel plate 101 has a 10-30mm conductive strip sprayed with conductive paint reserved around the perimeter of the mounting surface. After installation, it is connected to the windshield conductive rubber pad 203. The windshield protective glass mounting metal frame 201 also has a 10-30mm conductive strip sprayed with conductive paint reserved around the perimeter of the mounting surface. After installation, it is connected to the windshield conductive rubber pad 203. Finally, the windshield 200 is connected to the body-in-white 100.

[0046] Among them, adding a conductive rubber pad 203 to the windshield can effectively improve the rain-proofing ability;

[0047] like Figure 5As shown, the protective door 300 consists of a door electromagnetic shielding protective glass 305 embedded in a door glass mounting metal frame 303 to form a protective sliding window. The protective sliding window is connected to the metal frame 304 with a sliding window rail through a rail structure to form a protective glass window. The protective glass window is connected to the door protective steel plate 301 by bolts, and a door and window conductive rubber pad 307 is added in the middle of the connection to form the protective door 300.

[0048] The addition of a conductive rubber pad 307 between the protective glass window and the door protective steel plate 301 can effectively improve the rain-proofing ability.

[0049] The protective sliding window is connected to the metal frame 304 with sliding window rails via a rail structure. The two are connected by a rail conductive sealing strip 306 installed on the metal frame 304 with sliding window rails. The protective sliding window remains connected to the metal frame 304 with sliding window rails during the fixing and sliding process.

[0050] The door protective steel plate 301 has a 10-30mm uncoated strip 310 around the perimeter of the protective glass window mounting surface. Conductive paint is sprayed on the uncoated strip, and after installation, it is connected to the protective glass window.

[0051] The protective door 300 is connected to the body-in-white 100 via a hinge to open and close. When the protective door 300 is closed via the hinge, it comes into close contact with the door conductive sealing strips 309 embedded in the edges of the first body sheet metal 105 and the second body sheet metal 106 welded to the side protective steel plate 104, thus forming a conductive connection. The door conductive sealing strips 309 also come into close contact with the door sheet metal 302, thereby enabling the protective door 300 to form an effective conductive connection with the body-in-white 100.

[0052] like Figure 6 As shown, after the first body sheet metal 105 and the second body sheet metal 106 are welded together, a 10-30mm uncoated strip is reserved around the edge of the door conductive sealing strip 309. After the conductive paint is sprayed, the door conductive sealing strip 309 is embedded, and the door conductive sealing strip 309 forms an effective connection with the side protective steel plate 104.

[0053] The door sheet metal 302 is welded to the door protective steel plate 301. A 10-30mm uncoated strip is left around the contact position with the door conductive sealing strip 309 and then coated with conductive paint. When the door is closed, the door sheet metal 302 and the door conductive sealing strip 309 are tightly pressed into contact, and the two are effectively connected. The door frame sealing strip has a steel spring inside, and silver-plated aluminum powder, nickel powder, and graphite powder are added to the rubber of the sealing strip. It has deformation and rebound capabilities and conductivity, and is a conductive sealing strip that is inserted into the door frame and connected to the body.

[0054] The door sealing strip 308 is installed on the door sheet metal 302. When the protective door 300 is closed, it is in close contact with the second body sheet metal 106, forming a double sealing structure with the door conductive sealing strip 309 to ensure the rain sealing effect of the opening and closing parts.

[0055] like Figure 7 As shown, the front bulkhead 400 of the vehicle body is the main mounting structure for many chassis components. It is necessary to add through holes at the mounting locations of chassis components to accommodate the installation of the steering wheel, gear lever, electrical wiring harness, etc. in the passenger compartment. Conductive paint is sprayed on the uncoated areas of the mounting through holes for the components. When the components are installed, corresponding conductive pads are added in the middle to promote the formation of a conductive structure between the front bulkhead of the vehicle body and the components, and then to the vehicle body.

[0056] The ventilation holes include air conditioning ventilation holes, vehicle body ventilation holes, etc. Waveguide plates are installed at the ventilation hole locations. The waveguide plates are connected to the outer periphery of the ventilation holes with a 10-30mm conductive coating material to form a conductive structure. The waveguide plates utilize the waveguide's principle of conducting and cutting off electromagnetic waves to achieve electromagnetic wave shielding. Waveguide plates of corresponding specifications are developed according to the equipment's operating frequency and shielding effectiveness requirements.

[0057] The components include functional parts such as wiring harnesses, pipes, and steering columns that are installed through the vehicle compartment. The sealing gaskets used during the installation of the components are replaced with conductive sealing rings. Conductive adhesive is applied between the conductive sealing rings and the conductive coating material on the outer periphery of the components to ensure a seal while also creating effective conductivity between the components and the vehicle body.

[0058] Through the above technologies and processes, the passenger compartment after the vehicle assembly is completed forms a continuous conductor, and a continuous equipotential body is formed in the shielding layer, so as to absorb and reflect electromagnetic wave energy and achieve the purpose of shielding electromagnetic waves.

After process planning, a 10-30mm wide electrophoretic corrosion-resistant special tape was pasted around the relevant installation components. Then, electrophoretic coating was applied to the body-in-white with local protection. After coating, the body-in-white was cleaned and dried, and the corrosion-resistant tape was removed, forming a 10-30mm wide uncoated strip after electrophoresis of the entire vehicle.

The front windshield 200 is connected to the protective structure of the vehicle body by bolts. The front windshield 200 is conductive to the body-in-white 100. A windshield conductive rubber pad 203 is added between the two to improve the rain sealing capability.

The protective glass window is connected to the protective steel plate 301 of the door by bolts. A door and window conductive rubber pad 307 is added between the metal frame 304 with sliding window rails and the protective door 300 to improve the rain sealing ability.

[0065] S500: Door-to-body connection: A conductive sealing strip 309 is embedded in the edge of the body sheet metal, with an uncoated strip left, coated with conductive paint, and connected to the side protective steel plate 104. The door sheet metal 302 is welded to the door protective steel plate 301, with an uncoated strip left, coated with conductive paint, and the two make conductive contact. The door hinge is connected to the body-in-white 100 to achieve opening and closing. When the door is closed, it is in close contact with the body sheet metal, forming a connection. A door sealing strip 308 is installed, which is pressed tightly against the body sheet metal when the protective door 300 is closed, forming a double-seal structure.

[0066] S600: Assembly of the front body: The front body 400 is welded together with the front windshield 200, side panels, rear body and other structures to form the body-in-white 100. Through holes are added at the installation positions of chassis parts, conductive paint is sprayed, and conductive pads are added during installation to promote the formation of a conductive structure between the front body and the parts.

[0067] S700: Treatment of vent holes and through-cabin components: Install waveguide plates at the vent hole positions and connect them to the uncoated strip positions to form a conductive structure. Apply conductive paint to the uncoated strip around the installation perimeter of through-cabin components. Replace the gaskets during the installation of functional components with conductive sealing rings. Apply conductive adhesive between the conductive sealing rings and the conductive paint.

[0068] S800: Overall Connection: All components are assembled onto the body-in-white 100 to complete the final assembly of the armored special vehicle.

A method for implementing an electromagnetic shielding system for armored protective special vehicles according to any one of claims 1-4, characterized in that, Includes the following steps: S100: Body treatment: First, the body-in-white (100) is manufactured by cutting, bending, stamping and welding steel plates for the structural components required for the body-in-white (100); the connection positions between the body-in-white (100) and the protective glass, windshield (200), protective door (300) and related parts are determined. After process planning, a 10-30mm wide electrophoretic corrosion-resistant special tape is pasted in the area that needs to be conductive. Then, the body-in-white with local protection is electrophoretically coated. After coating, it is cleaned and dried, and the corrosion-resistant tape is removed to form a 10-30mm wide uncoated strip after the whole vehicle is electrophoretically coated. S200: Application of conductive coating: Apply conductive paint to the uncoated areas for corrosion resistance treatment to form conductive paths. These areas include the perimeter of the doors, the perimeter of the protective glass installation, the perimeter of the vents, and the perimeter of the installation of related components. After the coating is completed, the body-in-white (100) enters the final assembly workshop to begin assembly, thereby forming an armored protective special vehicle. S300: Front windshield assembly: The front windshield protective glass (202) with embedded electromagnetic shielding film is fixedly installed in the front windshield protective glass mounting metal frame (201) to form the front windshield (200). The front windshield (200) is connected to the protective structure of the vehicle body by bolts. The front windshield (200) is connected to the white body (100). A front windshield conductive rubber pad (203) is added between the two to improve the rain sealing ability. S400: Assembly of the protective door: The protective glass (305) of the door with embedded electromagnetic shielding film is fixedly installed in the metal frame (303) of the door glass installation to form a protective sliding window. The protective sliding window is connected to the metal frame (304) with sliding window rails through the sliding rail structure. The protective sliding window and the metal frame (304) with sliding window rails are connected to form a protective glass window. The protective glass window is connected to the door protective steel plate (301) by bolts. A door and window conductive rubber pad (307) is added between the metal frame (304) with sliding window rails and the protective door (300) to improve the rain sealing ability. S500: Door-to-body connection: A door conductive sealing strip (309) is embedded in the edge of the body sheet metal, with an uncoated strip reserved and coated with conductive paint, and connected to the side protective steel plate (104). The door sheet metal (302) is welded to the door protective steel plate (301), with an uncoated strip reserved and coated with conductive paint, and the two are in conductive contact. The door hinge is connected to the body-in-white (100) to achieve opening and closing. When the door is closed, it is in close contact with the body sheet metal to form a connection. A door sealing strip (308) is installed, which is in close contact with the body sheet metal when the protective door (300) is closed to form a double sealing structure. S600: Assembly of the front body: The front body (400) is welded with the structure including the front windshield (200), side panels and rear panels to form the body-in-white (100). Through holes are added at the installation positions of chassis components, conductive paint is sprayed, and conductive pads are added during installation to promote the formation of a conductive structure between the front body and the components. S700: Treatment of vent holes and through-cabin components: Install waveguide plates at the vent hole positions and connect them to the uncoated strip positions to form a conductive structure. Apply conductive paint to the uncoated strip around the installation perimeter of through-cabin components. Replace the gaskets during the installation of functional components with conductive sealing rings. Apply conductive adhesive between the conductive sealing rings and the conductive paint. S800: Overall connection: All components are assembled onto the white body (100) to complete the final assembly of the armored protective special vehicle. Through the above steps, the doors, windows, ventilation holes and cabin components are electrically connected to the body through conductive rubber, conductive paint and conductive sealing strips, so that the conductive materials of the entire crew compartment are interconnected to form a continuous conductor.
