Description

Technical Field

[0001] This utility model relates to the field of automotive parts and vehicle communication technology, and in particular to a silver-plated glass with an integrated antenna structure and an automotive part. Background Technology

[0002] With the evolution of new energy vehicle design, panoramic sunroofs and silver-plated windshields have become mainstream features. To enhance cabin comfort, panoramic sunroofs, including the windshield, typically have a silver coating (such as a Low-E coating) to reflect infrared rays and achieve heat insulation. However, as a conductive metal film, the silver coating has a strong shielding effect on electromagnetic waves (Faraday cage effect), causing the vehicle's onboard radio antenna installed under the glass to be unable to receive signals properly.

[0003] Existing solutions typically employ external shark fin antennas, but this not only disrupts the vehicle's streamlined appearance and increases air resistance, but also severely limits the installation space for external antennas, especially given that panoramic sunroofs occupy a large portion of the roof area. Therefore, how to efficiently integrate the antenna with silver-plated glass, ensuring both heat insulation and signal gain, is a pressing technical challenge. Utility Model Content

[0004] To address the conflict between signal shielding and aesthetic design in existing technologies, this invention provides a silver-plated glass and automotive component with an integrated antenna structure that solves the signal shielding problem while maintaining an aesthetically pleasing appearance.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A silver-plated glass with an integrated antenna structure, comprising: glass substrate, A silver-plated heat insulation layer is disposed on the surface of a glass substrate; The black ink area is located at the edge of the glass substrate; A localized silver removal area is set within the projection range of the black ink area; A conductive antenna element is disposed within a local silver removal area, and equal net space gaps are formed between the two sides of the conductive antenna element and the boundary of the local silver removal area.

[0006] Furthermore, the width W of the local silver removal area is 38~42mm.

[0007] Furthermore, the shape of the local silver removal area is adapted to the outer contour shape of the conductive antenna element, and the conductive antenna element is centrally located within the local silver removal area along the width direction.

[0008] Furthermore, the conductive antenna unit is a thin film structure formed by screen printing of conductive silver paste, with a thickness of 8μm~15μm.

[0009] Furthermore, the localized silver-removed area is a radio frequency window formed by removing the silver-plated heat insulation layer at the corresponding location using a laser ablation process.

[0010] Furthermore, the black ink area completely covers the localized silver-free area and the conductive antenna unit, making the conductive antenna unit invisible from both the inside and outside of the glass substrate.

[0011] Furthermore, the silver-plated heat insulation layer remains continuous in the area except for the local silver-free region, in order to shield electromagnetic interference from in-vehicle electronic devices; the conductive antenna unit receives external radio frequency signals through the local silver-free region.

[0012] Furthermore, the conductive antenna unit includes at least one of an FM antenna unit, an AM antenna unit, or a DAB antenna unit.

[0013] Furthermore, the glass substrate is the glass substrate of a panoramic glass and / or a windshield.

[0014] This utility model also relates to an automotive component, including the aforementioned silver-plated glass with an integrated antenna structure.

[0015] Beneficial effects: (1) High efficiency of wave transmission: By opening a special "radio frequency window" on the silver plating layer and a local silver removal area, the signal shielding of the metal film is effectively broken, providing sufficient electromagnetic clearance for the antenna and ensuring the stability of the radio signal (AM / FM / DAB);

[0016] (2) Layout optimization: The antenna is arranged in a central position, which makes the antenna induced current distribution uniform, reduces the parasitic capacitance interference generated by the metal edge, and optimizes the impedance matching. (3) Ultimate integration of appearance: The antenna is hidden in the black ink area (black area), and the traces of silver removal and antenna lines cannot be directly observed from the outside of the vehicle, which realizes the visual integrity of the whole vehicle and reduces wind resistance; (4) Strong protection: The black ink layer covers the antenna and the silver removal area, which can effectively block ultraviolet rays, prevent the antenna silver paste from oxidizing and the silver removal boundary from deteriorating, and extend the service life; (5) Improved EMC and cable transmission loss: The antenna is connected to the metal button on the edge of the glass through printed pins, and then connected to the amplifier fixed on the sheet metal of the roof beam through the corresponding connector. The output of the amplifier is then connected to the vehicle host. Compared with the traditional rear window antenna, the transmission loss caused by the cable length is reduced. At the same time, the antenna is located on the top of the vehicle, which also reduces the risk of electromagnetic interference from high-frequency power electronic devices such as the voltage conversion module at the rear of the vehicle.

The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0022] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

They are only for the convenience of describing this utility model and simplifying the description.

Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0026] This utility model aims to resolve the contradiction between signal shielding and appearance layout of panoramic silver-plated glass in new energy vehicles. Figures 1-3 This utility model relates to a silver-plated glass with an integrated antenna structure, comprising a glass substrate 1, a silver-plated heat insulation layer 2, a black ink area 3, a partially silver-removed area 4, and a conductive antenna unit 5. The silver-plated heat insulation layer 2 is disposed on the surface of the glass substrate 1; the black ink area 3 is disposed on the edge of the glass substrate 1; the partially silver-removed area 4 is disposed within the projection range of the black ink area 3; and the conductive antenna unit 5 is disposed within the partially silver-removed area 4, with equal net space gaps formed between the two side edges of the conductive antenna unit 5 and the boundary of the partially silver-removed area 4.

[0027] The width W of the local silver removal area 4 is 38~42mm, preferably 40mm.

[0028] The shape of the local silver removal area 4 is adapted to the outer contour shape of the conductive antenna element 5, and the conductive antenna element 5 is centrally located in the local silver removal area 4 along the width direction.

[0029] The conductive antenna element 5 is a thin film structure formed by screen printing of conductive silver paste, with a thickness of 8μm~15μm.

[0030] The localized silver removal area 4 is a radio frequency window formed by removing the silver-plated heat insulation layer 2 at the corresponding location using a laser ablation process.

[0031] The black ink area 3 completely covers the local silver-free area 4 and the conductive antenna unit 5, making the conductive antenna unit 5 invisible from the inside and outside of the glass substrate 1.

[0032] The silver-plated heat insulation layer 2 remains continuous in the area except for the local silver-free region 4, in order to shield electromagnetic interference from electronic devices inside the vehicle; the conductive antenna unit 5 receives radio frequency signals from outside the vehicle through the local silver-free region 4.

[0033] The conductive antenna unit 5 includes at least one of an FM antenna unit, an AM antenna unit, or a DAB antenna unit.

[0034] The glass substrate 1 is the glass substrate 1 of the panoramic glass and / or the windshield.

[0035] This utility model also relates to an automotive component, including the silver-plated glass with an integrated antenna structure as described above.

[0036] Reference Figures 1 to 3 In this embodiment, the silver-plated glass adopts a three-layer structure. The glass substrate 1 is tempered glass or laminated glass. A silver-plated heat-insulating layer 2 with a thickness of nanometers is coated on the inner surface of the glass substrate 1. Ceramic-textured black ink areas 3 are printed around the four edges of the glass.

[0037] In this embodiment, the key design element is that a laser ablation device is used to process the silver-plated heat insulation layer 2 in a specific area covered by the black ink area 3, removing the metallic substances in that area to form a localized silver-removed area 4 with a preferred width of 40 mm. This width represents the optimal balance between heat insulation performance and radio frequency performance.

[0038] The conductive antenna element 5 (using an FM radio antenna as an example in this embodiment) is screen-printed onto the partially silver-free area 4. To obtain the optimal radiation pattern and gain, the antenna element 5 is precisely positioned along the geometric center line of an area preferably 40mm wide. At this point, the net space gaps formed between the left and right sides of the antenna element 5 and the boundary of the silver plating layer are exactly equal. The antenna element 5 is connected to the antenna amplifier inside the vehicle via a feed point at its end.

[0039] The structure creates a localized silver-removing area with a preferred width of 40mm within the projection range of the black area on the glass substrate using a laser ablation process. Within this area, an antenna unit is centrally positioned by screen printing an 8-15μm thick conductive silver paste. An equal net space is reserved between the unit and the silver-plated heat insulation layer on both sides, allowing it to be installed on the windshield and / or panoramic glass.

[0040] This structure utilizes a dedicated RF window to bypass the metal film shielding, ensuring stable AM / FM / DAB radio signal reception. The antenna's centered placement optimizes current distribution and impedance matching. Hidden within a dark area, the antenna maintains visual integrity while offering low wind resistance. Black ink blocks ultraviolet radiation, preventing antenna oxidation and aging. Simultaneously, the antenna connects to the vehicle's main unit via a metal button and amplifier, reducing cable transmission loss, minimizing electromagnetic interference from high-frequency in-vehicle equipment, effectively improving EMC performance, and extending antenna lifespan.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
