Description

Technical Field

[0001] The utility model relates to the technical field of automobile electromagnetic protection, in particular to an electromagnetic protection structure of a vehicle window and an electromagnetic protection vehicle. Background Art

[0002] In some special vehicles, in order to ensure the normal operation of dedicated electronic equipment in the vehicle and avoid interference from external radiation signals, the vehicle cab (or the entire vehicle) needs to be effectively electromagnetically protected.

[0003] Although existing automobile bodies are made of metal, which inherently provides magnetic shielding, existing technologies use sealing strips to connect the vehicle's body frame to the window glass, which provides both sealing and cushioning. However, because both the window glass and the sealing strips are non-conductive, the windows are the largest leakage points in the electromagnetic shielding, and the amount of leakage directly affects the shielding effectiveness of the entire vehicle. Utility Model Content

[0004] In view of the above-mentioned defects, the technical problem to be solved by the present invention is to provide an electromagnetic protection structure for vehicle windows and an electromagnetic protection vehicle, wherein the electromagnetic protection structure can improve the electromagnetic shielding capability at the vehicle windows.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions:

[0006] In a first aspect, an electromagnetic protection structure for a vehicle window is provided, comprising a vehicle window arranged on a vehicle body frame, a rubber strip being provided at the connection between the glass of the vehicle window and the vehicle body frame, a transparent conductive film being affixed to one side of the glass, a conductive covering being provided on the rubber strip, the conductive covering being overlapped and connected to the transparent conductive film and the vehicle body frame, and the transparent conductive film being conductively connected to the vehicle body frame through the conductive covering.

[0007] By adopting this solution, the transparent conductive film applied to the vehicle window glass is electrically connected to the vehicle frame via a conductive cover, providing magnetic shielding capabilities at the vehicle window, thereby enhancing vehicle safety. Furthermore, due to the transparent conductive film's excellent light transmittance, it not only ensures magnetic shielding at the vehicle window, but also maintains light transmittance and provides a good field of view for vehicle occupants. Both the conductive cover and the transparent conductive film can be installed on existing vehicle bodies, making retrofitting the vehicle to enhance magnetic shielding capabilities cost-effective.

[0008] Preferably, the vehicle window is a front or rear windshield of a vehicle. The adhesive strip is provided with two first slots, with the edge of the glass correspondingly inserted into one of the first slots. The connection between the vehicle frame and the vehicle window is provided with a first protrusion, with the first protrusion correspondingly inserted into the other first slot. The conductive cover is provided on the same side of the adhesive strip as the transparent conductive film. Since the glass of the front and rear windshields of the vehicle is fixed and its position does not change, the conductive cover need only be provided on the same side of the adhesive strip as the transparent conductive film. Furthermore, the conductive cover only needs to be provided in the width direction of the portion where the adhesive strip overlaps and connects with the vehicle frame and the transparent conductive film, as well as the portion that spans the adhesive strip. This can reduce the amount of conductive cover required.

[0009] Preferably, the width of the overlapping connection between the conductive cover, the transparent conductive film and the vehicle body frame is greater than 10 mm, so as to ensure the conductive stability between the conductive cover, the vehicle body frame and the transparent conductive film.

[0010] Preferably, a metal foil is provided along the edge of the glass. One side of the metal foil is connected to the transparent conductive film, and the other side of the metal foil is overlapped and connected to the conductive cover. The transparent conductive film can be electrically connected to the conductive cover through the metal foil. The metal foil enhances the stability of the electrical conduction between the transparent conductive film and the conductive cover.

[0011] Preferably, the metal foil is copper foil.

[0012] Preferably, the window is a side window of a car, and two rubber strips are provided, one on the inner and outer sides of the glass, and the conductive cover is provided on the rubber strip on the same side as the transparent conductive film. This ensures that the conductive continuity between the window glass and the vehicle frame is maintained when the glass of the liftable window moves up and down.

[0013] Preferably, the rubber strip is provided with a second slot, and the conductive cover wraps around the strip. The connection between the vehicle frame and the glass has two second protrusions corresponding to the second slots. The second protrusions are embedded in the corresponding second slots, and a portion of the conductive cover is sandwiched between the corresponding second slots and second protrusions. Because the conductive cover wraps around the rubber strip, the connection between the conductive cover and the rubber strip is more stable. Furthermore, the portion of the conductive cover sandwiched between the second slots and the second protrusions forms a stable overlapping connection with the second protrusions, thereby ensuring stable electrical conduction between the conductive cover and the vehicle frame.

[0014] Preferably, the conductive covering is a conductive cloth, which has good electrical conductivity, is relatively soft, and is easy to install. It is also not easy to scratch the glass of the vehicle window when the conductive cloth is in direct contact with the vehicle window.

[0015] Preferably, the transparent conductive film and the conductive covering are both arranged on the inner side of the vehicle window.

[0016] In a second aspect, the present invention further provides an electromagnetic protection vehicle, comprising the above-mentioned vehicle window electromagnetic protection structure.

[0017] In summary, the electromagnetic protection structure for a vehicle window provided by the present invention has at least the following beneficial effects:

[0018] 1. The car windows also have magnetic shielding capabilities, so that the car as a whole has better magnetic shielding capabilities.

[0019] 2. It can be installed on existing automobile products, and the cost of automobile modification is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make those skilled in the art better understand the technical solution of the utility model, Figure 1-4 The present invention is further described in detail with reference to the following specific embodiments.

[0027] Example 1

[0028] See also Figure 1 and Figure 2This embodiment provides an electromagnetic protection structure for a vehicle window, including a vehicle window mounted on a vehicle frame. A rubber strip 2 is provided at the connection between the glass 1 of the vehicle window and the vehicle frame, and the rubber strip 2 surrounds the edge of the glass 1 of the vehicle window. A transparent conductive film 3 is affixed to one side of the glass 1 of the vehicle window, and a conductive covering member 4 is provided on the rubber strip 2. The conductive covering member 4 is specifically provided along the entire length of the rubber strip 2. The conductive covering member 4 is superimposed and connected to the transparent conductive film 3 and the vehicle frame, and the transparent conductive film 3 can be conductively connected to the vehicle frame through the conductive covering member 4. The transparent conductive film 3 is a prior art, and specifically can be an ITO transparent conductive film in the prior art. The conductive covering member 4 can specifically be a conductive cloth in the prior art.

[0029] By adopting the above solution, the transparent conductive film 3 is affixed to the vehicle window glass 1 and electrically connected to the vehicle frame via the conductive cover 4, providing magnetic shielding capabilities at the vehicle window, thereby improving the safety of the entire vehicle. Furthermore, due to the excellent light transmittance of the transparent conductive film 3, while maintaining magnetic shielding performance at the vehicle window, it also ensures light transmittance and provides a good field of vision for vehicle occupants. Both the conductive cover 4 and the transparent conductive film 3 can be installed on existing vehicle bodies, making the cost of retrofitting vehicles to enhance magnetic shielding capabilities low.

[0030] Specifically, in this embodiment, the vehicle window is a front or rear windshield of a car. The rubber strip 2 is provided with two first slots 5, symmetrically distributed along the diameter of the rubber strip 2. The edge of the window glass 1 is correspondingly inserted into one of the first slots 5. A first protrusion 6 is provided at the connection between the vehicle frame and the window, and the first protrusion 6 is correspondingly inserted into the other first slot 5. The conductive cover 4 is provided on the same side of the rubber strip 2 as the transparent conductive film 3.

[0031] To ensure stable electrical conduction between the conductive cover 4, the transparent conductive film 3, and the vehicle frame, the width of the overlapping connection between the conductive cover 4, the transparent conductive film 3, and the vehicle frame is preferably greater than 10 mm. The length of the overlapping connection between the conductive cover 4, the transparent conductive film 3, and the vehicle frame should also be limited to a minimum, to avoid affecting the normal light transmission function of the vehicle window.

[0032] To improve the stability of electrical conduction between the conductive cover 4 and the transparent conductive film 3, a circle of metal foil 7 is further provided along the edge of the vehicle window glass 1. One side of the metal foil 7 is connected to the transparent conductive film 3, and the other side of the metal foil 7 is overlapped and connected to the conductive cover 4. The transparent conductive film 3 can be electrically connected to the conductive cover 4 through the metal foil 7. Preferably, the metal foil 7 is copper foil.

[0033] Please continue reading Figure 1 Preferably, the transparent conductive film 3 and the conductive cover 4 are both arranged on the inner side of the vehicle window.

[0034] Example 2

[0035] See also Figure 3 and Figure 4 The difference from Example 1 is that the vehicle window is a side window of an automobile, and two rubber strips 2 are provided, one on the inside and one on the outside of the vehicle window glass 1. A transparent conductive film 3 is provided on the inside of the vehicle window glass 1, and a conductive cover 4 is provided on the rubber strip 2 on the same side as the transparent conductive film 3. Specifically, the rubber strip 2 is provided with a second groove 8, and the conductive cover 4 wraps around the rubber strip 2. The connection between the vehicle body frame and the vehicle window glass 1 has two second protrusions 9 corresponding to the second grooves 8. The second protrusions 9 are embedded in the corresponding second grooves 8, and the conductive cover 4 is partially sandwiched between the corresponding second grooves 8 and the second protrusions 9.

[0036] In this embodiment, the side windows of the vehicle can be fixed or lift-type. For fixed-type windows, the glass 1 and the conductive cover 4 can simply abut against each other at the joint. Alternatively, conductive adhesive can be applied between the conductive cover 4 and the transparent conductive film 3 to enhance the conductivity and stability of the connection between the conductive cover 4 and the transparent conductive film 3. For lift-type windows, since the glass 1 needs to be raised and lowered, the conductive cover 4 can simply be in close contact with the transparent conductive film 3 due to the elastic force of the adhesive strip 2.

[0037] Based on the same inventive concept, the present invention also provides an electromagnetic protection vehicle, comprising the electromagnetic protection structure of the vehicle window of the above-mentioned embodiment 1 or embodiment 2.
