One of the loudest projects among modern electric cars (and cars in general) is the Tesla Cybertruck — an unusual pickup truck with a futuristic design. Among its features is armored glass, which suffered a major defeat during the first demonstration. Twice.
The company has been investing in development, including glass, for years. Now Tesla has received a new interesting patent. In particular, it also talks about problems with current production:
Generally, such processes for making glass structures are limited by the amount of curvature or bending achievable with the glass. For example, typically only smooth, high radius of curvatures (e.g., radius of curvature of 1-3 meters or more), are used for automotive glass structures.
Tesla development will offer shorter radiuses of curvature:
In some embodiments, a process for forming an automotive glass structure having one or more feature lines (or curves/bends) includes applying localized heat to one or more locations of the glass structure, whereby the glass structure bends at the location of the localized heat. In some examples, the glass structure is supported by a support tool such that as localized heat is applied gravity forces the glass structure to bend at the one or more locations (e.g., along a longitudinal line of the glass), thereby forming a feature line or bend in the glass. In some examples, additional forces may be applied to the glass structure, e.g., via a press, vacuum air suction, or the like to aid in bending or shaping of the glass structure. In some examples, a radius of curvature of the feature line or bend in the glass structure at the one or more locations is between 2 mm and 5 cm.
This can also apply to laminated glass:
In another embodiment, a glass structure includes a first layer of glass having a feature line or bend in at least one location thereof. The feature line having a radius of curvature between 2 mm and 5 cm. In some examples, the glass structure is a multilayer glass structure and includes a second layer of glass including a first portion of glass and a second portion of glass, the first and second portions meeting at the feature line or bend in the first layer of glass. A polymer may be disposed between the first layer of glass and the second layer of glass.
And the more detailed drawing for the image of such glass was not a Semi truck, but a Cybertruck.
We remind you that the release of the futuristic pickup truck is scheduled for mid-2023.
