Description

Technical Field

[0001] This utility model relates to the field of vehicle window technology, specifically to a window structure with an internal heat insulation structure. Background Technology

[0002] In high-altitude and cold regions (typically referring to areas where extreme winter temperatures drop below -20°C), the window structures of vehicles, rail transit vehicles, and special-operation cabins have long faced the technical challenge of icing and frost formation on the material surfaces. As a key component of the enclosure structure, the windows of such equipment not only provide lighting, ventilation, and protection, but their thermal performance also directly affects the stability of the internal thermal environment and the safety of use. Existing window structures mostly employ traditional metal profile splicing designs. The high thermal conductivity of metal materials makes the profiles the primary channels for heat exchange. In extremely cold environments, the temperature difference between the external low temperature and the internal heating can reach over 40°C. Traditional profiles lack effective internal insulation, allowing heat to be rapidly conducted outwards through the profiles, causing the inner surface temperature of the profiles to easily drop below the dew point. Simultaneously, the sealing performance of the gaps between the profile splicing seams and the fit between the glass and the profile in traditional window structures is insufficient, allowing cold air from the outside to easily penetrate into the gaps, forming condensation that quickly freezes into frost in low-temperature environments.

[0003] The aforementioned icing and frosting issues can lead to a series of serious consequences: First, frost on the profile surface can hinder the sliding or rotation of the movable glass, causing the window opening and closing mechanism to jam, affecting the normal function of the equipment, and posing a threat to the driving safety of mobile equipment such as vehicles; Second, long-term repeated icing-melting cycles can damage the connection structure between the profile and the sealing components, accelerate the aging of the sealing strips and the corrosion of the profile, shorten the service life of the window, and increase maintenance costs; Third, water droplets generated by melting frost can seep into the interior of the equipment, damaging interior parts, electrical components and other auxiliary structures, further expanding the scope of the failure.

[0004] To alleviate the above problems, existing technologies have adopted improved solutions such as increasing the number of sealing strip layers or using low thermal conductivity profiles, but these still have significant drawbacks: simply increasing the number of sealing strips is insufficient to solve the heat conduction problem of the profile itself, and an unreasonable sealing structure design can easily lead to compression deformation and failure of the sealing strips; low thermal conductivity profiles are expensive, and no targeted insulation treatment is provided for the splicing gaps, so the thermal bridging effect still exists. In addition, some solutions do not consider the compatibility between the insulation structure and the moving parts of the window, resulting in increased resistance to the operation of the movable glass and affecting the operational flexibility of the window.

[0005] Therefore, developing an internally insulated window structure that can fundamentally block the heat conduction path of the profile, enhance the sealing and insulation performance of the gaps, and adapt to the operating requirements of movable glass is of great practical significance for solving the problem of icing and frosting of equipment windows in high-altitude and cold regions and improving the environmental adaptability and reliability of equipment.
