Description

Technical Field

[0001] This utility model relates to the field of electrically heated coated glass technology, and in particular to an electrically heated coated glass with a busbar electrode reinforcement structure. Background Technology

[0002] Electrothermal coated glass typically uses a transparent conductive film as the electrothermal function film and a metal material with good conductivity as the bus electrode material. The bus electrode material is electrically connected to the transparent conductive film through bonding. The current first passes through the bus electrode material and then disperses onto the transparent conductive film to achieve the electrothermal function.

[0003] In the existing technology, the bus electrode of electrically heated coated glass may have insufficient strength or poor conductivity in some cases. When the electrical bonding performance with the transparent conductive film fails, it will limit the performance and application of the electrically heated coated glass.

[0004] Therefore, an electrically heated coated glass with a busbar electrode reinforcement structure is provided to solve the above problems. Summary of the Invention

[0005] The main purpose of this invention is to solve the problem that the bus electrode of electrically heated coated glass may have insufficient strength or poor conductivity in some cases, and the electrical bonding performance with the transparent conductive film may fail, which would limit the performance and application of the electrically heated coated glass.

[0006] This utility model provides an electrically heated coated glass with a busbar electrode reinforcement structure, wherein the electrically heated coated glass with the busbar electrode reinforcement structure comprises:

[0007] An acrylic glass assembly includes a busbar on its surface. An electrically heated conductive film is laid on the upper surface of the acrylic glass, covering the busbar. A low-resistance conductive film is laid on the upper surface of the electrically heated conductive film above the busbar. A metal current-carrying sheet is positioned above the low-resistance conductive film above the busbar, and the metal current-carrying sheet and the low-resistance conductive film are fixedly connected by an adhesive.

[0008] Secondly, this utility model provides an electrically heated coated glass with a busbar electrode reinforcement structure, comprising: plexiglass, an electrically heated conductive film laid on the upper surface of the plexiglass, a low-resistance conductive film laid on the upper surface of the electrically heated conductive film, a busbar disposed directly above the low-resistance conductive film, a metal current-carrying plate disposed above the busbar, and the metal current-carrying plate and the busbar being fixedly connected by an adhesive.

[0009] Thirdly, this utility model provides an electrically heated coated glass with a busbar electrode reinforcement structure, characterized in that it comprises: plexiglass, on which a first busbar is disposed, and an electrically heated conductive film is laid on the upper surface of the plexiglass, the electrically heated conductive film covering the first busbar, a low-resistance conductive film is laid on the upper surface of the electrically heated conductive film located above the first busbar, a second busbar is disposed above the low-resistance conductive film located above the first busbar, and a metal current-carrying sheet is disposed on the upper surface of the second busbar, the metal current-carrying sheet and the low-resistance conductive film being fixedly connected by an adhesive.

[0010] Furthermore, the electrically heated conductive film is a metal or metal oxide film layer.

[0011] Furthermore, the busbar is a metal sheet busbar, a conductive silver paste busbar, or a conductive adhesive busbar.

[0012] Furthermore, the low-resistance conductive film includes a gold conductive film, a silver conductive film, or a copper conductive film.

[0013] Furthermore, the adhesive is a conductive adhesive or a conductive silver paste adhesive.

[0014] Furthermore, the metal current-carrying sheet includes metal wires, metal sheets, metal meshes, or metal braids.

[0015] This invention adds a low-resistance film layer region between the busbar and the conductive film, enhancing the overlap strength between the electrode and the conductive film and improving conductivity. The low-resistance film layer in the busbar region allows the maximum heating point of the electrically heated film to be located away from the busbar region. Microscopic defects existing between the various processes of conductive film construction and busbar electrode construction can be filled by the low-resistance film layer, reducing the risk of busbar electrode failure due to cracking caused by microscopic defects. This improves the electrically heated performance of the conductive film in the coated electrically heated glass, enhances the strength and durability of the busbar electrode, and extends the product's service life.
