The importance of automotive A-pillars to vehicle structural safety can be said to be self-evident, especially in today's increasingly stringent impact regulations in various markets, strengthening body safety has become one of the important goals of manufacturers when developing new cars, and it seems inevitable that A, B and C pillars will become more and more "bold". However, as long as you have driving experience, friends must understand that the thick vehicle A-pillar not only hinders the driving vision when driving, but also makes the visual blind spot problem more serious, and the traffic accidents caused by it are not uncommon. Recently, GM Group submitted a transparent A-pillar patent design drawing, through the use of special materials, so that the driving field of vision is no longer limited, if the future is expected to ensure the safety of driving and other passers-by after mass production, it can be said that the merit is a piece!
It is said that the patent diagram presented by GM Group envisions a design of A-pillar composed of a fusion of carbon fiber and a variety of composite materials, on the one hand, by "digging holes" in the A-pillar and filling in transparent tree esters to solve the vision problem. In order to maximize the field of view, GM Group has patented that this transparent opening area can be designed to be up to 8 cm (3.15 inches) wide and 39 .8cm (15.7 inches) high.
In the patent document, it is also pointed out that the transparent tree ester can emit 0.5 watts of power wire per square inch, which further provides debagging and de-icing uses, so that this transparent A-pillar can always maintain a clear field of vision. On the one hand, transparent tree esters and currents can also control their opacity, for example, at sunrise or sunset, to prevent unnecessary glare.
In order to ensure the structural strength of the A-pillar, as mentioned above, the carbon fiber material will be introduced to maintain a certain rigidity, on the one hand, the strength of the A-pillar will be strengthened by "layers of stacking" similar composite fibers. The patented design is speculated to be used in GM's brand cars in the future. As electrification approaches, this future generation-shifting design will not be the first to be seen in the production version of Cadillac Lyriq.
