Description

Technical Field

[0001] The present invention belongs to the technical field of passenger vehicle accessories, and particularly relates to a front windshield sunshade for passenger vehicles. Background Art

[0002] With the rapid development of the automotive industry, passenger vehicles have become an indispensable means of transportation in people's daily lives. However, despite the continuous progress of automotive technology, many detailed problems related to the user experience have not been fully resolved, especially in terms of comfort and privacy when the vehicle is parked. Among them, problems such as excessive interior temperature, aging of interior components, and insufficient privacy caused by the exposure of the front windshield to strong sunlight in summer have long troubled vehicle owners and automotive manufacturers.

[0003] With global warming, high-temperature weather in summer is becoming increasingly frequent, posing higher requirements for the comfort of the interior environment of passenger vehicles. In the hot summer, when the vehicle is exposed to direct sunlight for a long time, the interior temperature will rise rapidly, even exceeding the human comfort range. This not only affects the riding experience of the driver and passengers but may also cause damage to the interior components of the vehicle. In particular, the front windshield, as the main interface between the vehicle and the external environment, has a large area directly exposed to sunlight. And due to regulatory restrictions, it is usually not allowed to apply films to the front windshield, which further exacerbates the problems of increased interior temperature and aging of the interior. Interior components of the vehicle that are long-term exposed to sunlight, such as the instrument panel, steering wheel, seats, etc., will be strongly irradiated by ultraviolet rays, resulting in accelerated material aging, color fading, and even possible cracks or deformations. This not only shortens the service life of these components but also reduces the overall value of the vehicle. At the same time, since the front windshield cannot be film-coated, vehicle owners are more easily noticed from the outside when moving inside the vehicle, reducing the privacy of the vehicle. Summary of the Invention
