Description

Technical Field

[0001] The present invention relates to the technical field of special vehicles, and more specifically, to a vehicle door device with electromagnetic shielding function and a manufacturing method thereof. Background Art

[0002] With the rapid development of modern science and technology, vehicles are increasingly sensitive to electromagnetic environments and have higher requirements for electromagnetic compatibility. Especially in special fields such as military, medical, and scientific research, vehicles must have efficient electromagnetic shielding functions to protect internal equipment from external electromagnetic interference, while preventing the leakage of electromagnetic radiation generated by the vehicle itself, which would cause unnecessary impact on the external environment. However, there are many challenges in realizing electromagnetic shielding functions in vehicle body design, the most critical of which is how to ensure that the vehicle body can form a continuous and efficient conductor. In traditional vehicle body structures, although most materials are conductive, the opening parts on the vehicle body (such as doors, hoods, trunk lids, etc.) often contain large-area insulating sealing structures due to their functional requirements, such as rubber sealing strips, glass partitions, etc. These insulating parts significantly block the continuity of the vehicle body's conductive path, seriously weakening the overall electromagnetic shielding effectiveness of the vehicle body.

[0003] In order to solve this problem, some existing technologies use wire mesh sandwich electromagnetic shielding glass, which has a conductive shielding wire mesh embedded inside the glass, and is specially designed to make the shielding wire mesh conductively connected to the window frame, and then the window frame is provided with a connection surface that is in close contact with the metal body to achieve electromagnetic wave shielding. Although the above technical solutions have made significant progress in electromagnetic shielding in the window area, the processing difficulty is relatively high. The production process of wire mesh sandwich electromagnetic shielding glass is complicated, and the layout, density and bonding strength of the shielding wire mesh need to be precisely controlled, which increases the manufacturing cost and processing difficulty.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] Based on the above problems, the present invention is composed of a conductive side panel assembly 100, a conductive door assembly 200 movably connected thereto, and a window assembly 300 fixed to the upper part of the door assembly. The three are tightly connected through an efficient sealing assembly to jointly construct an electromagnetic shielding space. Among them, the window assembly 300, as a key part of the door device, is not only responsible for lighting and ventilation inside the vehicle, but also plays an important role in improving electromagnetic shielding performance. The assembly is mainly composed of a slide assembly 320, a window frame 330 and a conductive film glass 310. The close cooperation and special design between the three together construct an effective electromagnetic protection barrier.

[0034] First, the slide assembly 320 is designed to be both conductive and airtight as the guide rail and support structure of the window frame 330. The fixed connection between the connector 322 and the grooved sealing strip 321 not only ensures the stability of the window frame during the sliding process, but also makes the entire slide assembly part of the electromagnetic shielding network through the selection of conductive materials. In addition, the threaded hole design on the upper part of the connector 322 not only facilitates the fixed connection with the door assembly 200 and the sealing gasket 340, but also further enhances the continuity of the electromagnetic shielding through the through structure.

[0035] The window frame 330, as the supporting frame of the conductive film glass 310, is also made of conductive material. This design allows the window frame to effectively conduct and disperse electromagnetic radiation while bearing the weight of the glass, thereby protecting passengers in the car from external electromagnetic interference. It is worth noting that the connection between the window frame and the glass has also been carefully designed to ensure that the conductive film fits tightly to the window frame without any gaps, thereby further improving the electromagnetic shielding effect.

[0036] As the core part of the vehicle window assembly, the conductive film of the conductive film glass 310 is set in various ways, including external wrapping, internal inlaying or a combination of the two. This flexibility not only meets different design requirements, but also ensures that the conductive film can be evenly and effectively covered on the glass surface to form a solid electromagnetic protection layer. At the same time, the close fit between the conductive film and the window frame further enhances the overall electromagnetic shielding performance of the vehicle window assembly.

[0037] In addition to the above main structures, the window assembly 300 is also equipped with a conductive sealing gasket 340 and an O-shaped sealing strip 350. The sealing gasket 340 not only enhances the connection strength between the window assembly and the door, but also further enhances the electromagnetic shielding effect through its conductivity. The O-shaped sealing strip 350 realizes the sealing and electromagnetic shielding of the side of the window assembly.

[0044] In some preferred embodiments, the inner sealing strip 110 and the outer sealing strip 210 are made of vinyl silicone rubber mixed with a rubber strip of a conductive material, wherein the main components of the conductive material are silver-plated aluminum powder, nickel powder, and graphite powder, and the resistivity of the conductive sealing strip is less than 0.008Ω*cm. To ensure that the sealing strip is conductive and the door has good opening and closing force, the proportion of the conductive material of the sealing strip and the proportion of the rubber strip are formed according to a certain formula, and the compression deformation and compression force of the sealing strip are strictly controlled.

[0054] As another aspect of the present invention, it also relates to a method for manufacturing a vehicle door device with an electromagnetic shielding function, which is implemented by using the vehicle door device with an electromagnetic shielding function, and comprises the following steps:

[0055] S1, clean the contact surface and the mounting surface. Clean and wipe the contact surface and the mounting surface between the inner sealing strip 110, the outer sealing strip 210 and the sealing gasket 340 and the vehicle body with asphalt cleaning agent, and wipe off impurities such as drawing oil, rust-proof oil and dust; specifically, use a brush to dip in an appropriate amount of asphalt cleaning agent, and evenly apply it on the contact surface and the mounting surface between the inner sealing strip 110, the outer sealing strip 210, the sealing gasket 340 and the vehicle body. Pay special attention to corners and gaps to ensure that the cleaning agent can penetrate and dissolve impurities such as drawing oil, rust-proof oil and dust. Wipe the above areas repeatedly with a rag until the surface is clean and free of residue. For stubborn stains, use a scraper to gently scrape them off, but be careful to avoid scratching the metal surface. After cleaning, wipe again with a clean rag to ensure that all cleaning agents are removed.

[0056] S2, the whole body is processed, and polyimide tape of corresponding specifications is pasted along the contour shape of the contact surface and the mounting surface in S1 for masking (according to the contour shape of the contact surface and the mounting surface, the polyimide tape of corresponding specifications is cut to ensure that the edge of the tape is flat, without wrinkles or bubbles); the whole body is painted with electrophoretic topcoat, and before the whole body is electrophoretically coated, the surface of the body is ensured to be dry and free of moisture. During the electrophoretic coating process, parameters such as voltage, current and time are controlled to obtain a uniform and dense electrophoretic layer. Then the polyimide tape is removed, and a paint masking film and paper tape are used to perform reverse masking along the original masking area and the boundary line of the electrophoretic topcoat;

[0060] Grinding and cleaning: Use dry sandpaper to evenly grind the contact surface and mounting surface cleaned in S1 to remove the surface oxide layer and tiny protrusions. After grinding, use sticky gauze to carefully clean the grinding surface to remove dust and impurities generated by grinding.

[0061] Spraying conductive paint: Stir the conductive paint thoroughly and evenly, and use a spray gun to spray evenly on the polished surface. Pay attention to controlling the spraying distance and speed to avoid dripping or leaking. After spraying, let it stand at room temperature for 5 minutes to allow the conductive paint to initially solidify.

[0062] Remove masking and dry: Remove the paint masking film and paper tape to expose the conductive paint spray area. Place the spray area in an oven and dry at 90-100°C for 30 minutes to ensure that the conductive paint is fully cured and achieves optimal performance.

[0066] Replacement operation: Remove the original non-conductive sealing strips and gaskets in turn, taking care to avoid damaging the body surface and surrounding parts. Install the new conductive sealing strips and gaskets in the original position, ensuring that they are firmly installed and well sealed. Pay special attention to the joints and corners of the sealing strips to ensure tightness. Remove the original non-conductive glass 310, taking care to protect the window frame and surrounding parts from damage. Install the new conductive glass 310 in the original position, ensuring that it fits tightly with the window frame and is firmly fixed. During the installation process, pay attention to the contact between the conductive film and the window frame to ensure good conductivity.
