Description

Technical Field

[0001] The present invention belongs to the technical field of automobile manufacturing, and more specifically, relates to an electromagnetic shielding system for an armored protection special vehicle and an implementation method thereof. Background Art

[0002] With the evolution of modern warfare, informatization and electrification have become important characteristics of warfare. As an important equipment for modern high-tech warfare, the electronic systems of special vehicles face severe challenges in the electromagnetic environment. In a complex battlefield environment, special vehicles must not only resist traditional firepower attacks, but also be able to effectively protect electronic information systems from electromagnetic threats such as electromagnetic pulses (EMP). Traditional armored vehicles mainly focus on physical protection, while ignoring the importance of electromagnetic protection. With the development of electronic warfare and cyber warfare, the electromagnetic compatibility issues of special vehicles have become increasingly prominent. Electronic equipment inside vehicles is susceptible to interference in complex electromagnetic environments, affecting the mobility and safety of vehicles. Windows, equipment holes and cables are the main sources of electromagnetic interference, and existing shielding technologies often have problems such as heavy weight, high cost, and complex installation. Armored protection special vehicles are widely used in various arms because of their good protection capabilities, high strength, high mobility, extremely high environmental adaptability, reliability and other characteristics. The armored protection special vehicles are light and highly mobile armored vehicles with strong carrying capacity and modification space. They are important platforms for service support and informationized warfare, and have been successfully applied in artillery and radar. At present, as a radar carrying platform, when the radar is operated in the vehicle and the work is carried out, the emitted electromagnetic waves will also penetrate the vehicle body, causing electromagnetic damage to the operator. Therefore, as a radar carrying platform, an armored protection special vehicle urgently needs to achieve a certain ability of electromagnetic shielding, so as to reduce electromagnetic radiation damage and protect the operator on board.

[0003] The existing solutions all provide electromagnetic shielding for the whole vehicle by installing windows or doors with electromagnetic shielding function, which cannot meet the shielding requirements for high-intensity electromagnetic, especially for complex or rapidly changing electromagnetic environments. On the other hand, the shielding design of windows or doors is not compatible with the shielding measures of other parts of the vehicle, which may form a channel for electromagnetic leakage and affect the final shielding effect.

[0004] As a carrying platform, the armored protection special vehicle is very close to the radar transmitting device. Strong electromagnetic waves will penetrate the body of the vehicle and thus harm the health of the operator. The existing vehicle structure is difficult to meet the electromagnetic shielding requirements. Targeted design and process implementation are required based on the performance of the vehicle to form a conductive structure for the entire passenger compartment, thereby meeting the passenger compartment's electromagnetic shielding requirements of 300MHZ-18.5GHz and 30dB. Summary of the invention

[0005] In view of the above defects or improvement needs of the prior art, the present invention provides an electromagnetic shielding system for armored special vehicles.

A method for implementing the electromagnetic shielding system for armored special vehicles according to claims 1-9, characterized in that: The steps include: S100: Body processing: First, the body-in-white (100) is manufactured by cutting, bending, stamping and welding the structural parts required for the body-in-white (100) with steel plates; the connection positions between the body-in-white (100) and the protective glass, the front windshield (200), the protective door (300) and related parts are clarified, and after process planning, a 10-30 mm wide electrophoretic corrosion-resistant special tape is pasted on the area that needs to be conductive, and then the body-in-white with local protection is electrophoretically coated, and after coating, it is cleaned and dried, and the corrosion-resistant tape is removed to form a 10-30 mm wide uncoated tape after electrophoresis of the whole vehicle; S200: Application of conductive coating: spraying conductive paint on uncoated locations for corrosion resistance treatment to form conductive paths. These locations include the door circumference, protective glass installation circumference, vent circumference, and installation-related parts circumference. After the coating is completed, the body-in-white (100) enters the final assembly workshop and begins assembly, thereby forming an armored protection special vehicle. S300: front windshield assembly: a windshield protective glass (202) embedded with an electromagnetic shielding film is fixedly installed in a windshield protective glass installation metal frame (201) to form a 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 rainproof sealing capability; S400: Assembling a protective door: fixing a door protective glass (305) embedded with an electromagnetic shielding film in a door glass mounting metal frame (303) to form a protective sliding window, connecting the protective sliding window to a metal frame (304) with a sliding window rail via a sliding rail structure, conducting the protective sliding window to the metal frame (304) with a sliding window rail to form a protective glass window, connecting the protective glass window to a door protective steel plate (301) via bolts, and adding a door and window conductive rubber pad (307) between the metal frame (304) with a sliding window rail and the protective door (300) to improve the rainproof sealing capability; S500: Conductivity between the door and the body: embed the conductive sealing strip (309) of the door at the edge of the body sheet metal, reserve an uncoated strip, spray conductive paint, and conduct with the side protective steel plate (104). The door sheet metal (302) is welded to the door protective steel plate (301), reserve an uncoated strip, spray conductive paint, and the conductive contact between the two is achieved. The door hinge is connected to the white body (100) to achieve opening and closing; when the door is closed, it is in close contact with the body sheet metal to form conduction. Install the door sealing strip (308), and when the protective door (300) is closed, it is in close contact with the body sheet metal to form a double sealing structure; S600: Assembly of the front body: The front body (400) is welded with the front windshield (200), the side body, the rear body and other structures to form a body in white (100), additional holes are opened at the installation position of chassis components, conductive paint is sprayed, and conductive rubber pads are added during installation to form a conductive structure between the front body and the components; S700: Treatment of vents and cabin penetration parts: Install a waveguide plate at the vent position and connect it to the uncoated belt position to form a conductive structure. Apply conductive paint to the uncoated belt around the cabin penetration parts installation circle. Replace the sealing gasket during functional parts installation with a conductive sealing ring. Apply conductive glue between the conductive sealing ring and the conductive paint. S800: Overall connection: All components are assembled onto the body in white (100) to complete the final assembly of the armored special vehicle. Through the above measures, the doors, windows, air vents and cabin penetration parts are all electrically connected to the body through conductive rubber, conductive paint and conductive sealing strips, so that the conductive materials of the entire passenger compartment are interconnected to form a continuous conductor.
