Abstract

The invention discloses electrochromic automobile glass with electric heating and electromagnetic shielding functions. According to the electrochromic automobile glass, a first glass layer, an electrochromic module, a first grid layer, a second grid layer, a bonding layer and a second glass layer are sequentially stacked in a thickness direction. The electrochromic automobile glass is characterized in that the first grid layer comprises a first transparent substrate and a plurality of first metal wires arranged in a parallel wiring mode, the first metal wires are distributed at the side, facing the electrochromic module, of the first transparent substrate, the second grid layer comprises a second transparent substrate and a plurality of second metal wires arranged in a parallel wiring mode, and the second metal wires are distributed at the side, facing the second glass layer, of the second transparent substrate. The electrochromic automobile glass can achieve the electromagnetic shielding function and the electric heating function simultaneously, and the electromagnetic shielding function is not limited by an electromagnetic radiation direction.

Description

Technical field: [0001] The invention relates to the technical field of photoelectric functional glass, in particular to an electrochromic automotive glass with electric heating and electromagnetic shielding. Background technique: [0002] Electrochromic technology is a technology that can be driven by an external DC voltage and can reversibly adjust the transmittance of visible light and near-infrared light in the solar spectrum. Therefore, if this technology is applied to automotive glass, it can effectively adjust the The light transmission of window glass and the transmission of solar energy can achieve the purpose of dimming and energy saving. [0003] However, there are some deficiencies in the actual application of electrochromic glass products: 1.

Problems solved by technology

[0003] However, there are some deficiencies in the actual application of electrochromic glass products: 1. At present, the conductive layer of the electrochromic functional film uses ITO conductive film, and the conductivity of ITO conductive film is poor, making the electrochromic film The discoloration rate is too slow, especially for inorganic electrochromic products (ie: all-solid-state electrochromic devices), which results in poor experience for customers; 2. Poor low-temperature performance, that is: when the ambient temperature is too low (<-10°C), the discoloration function of the electrochromic glass gradually slows down or even does not change color, so that the product has the problem of discoloration failure when it is applied to buildings or cars in cold winter areas

Therefore, in the actual application process, because we cannot judge the propagation direction of electromagnetic radiation, there are certain limitations in the application process.
