Original title: Tesla announced its Cybertruck bulletproof glass patent
According to foreign media reports,TeslaAnnounced the bulletproof glass patent content of its electric pickup Cybertruck.TeslaCEO Elon Musk has talked about the bulletproof glass many times. Cybertruck’s durability has always been one of the highlights of the vehicle.This patent describes this multi-layer design, which can prevent the vehicle glass from being scratched, cracked or broken, so that the car owner does not need to buy a new windshield or car window, and will be used in the futureTeslaOf many models.
According to the patent, the “multi-layer glass stack” (multi-layer glass stack) combination has a failure probability of only 10% under an impact force of 2 J. Tesla’s multilayer glass stack consists of three layers: the inner layer, which is chemically strengthened, has a high flexibility and a thickness of 0.5-1.1 mm; the middle layer, which has energy absorbing properties, bonds the inner and outer layers; and the outer layer, The thickness is 2-5 mm, it contains non-“soda lime, low CTE (coefficient of thermal expansion), high-density glass” and is composed of borosilicate. Borosilicate is a low-melting glass made of silicon dioxide and boron oxide, which is more resistant to thermal shock than ordinary glass.
Tesla focuses on manufacturing highly durable automotive glass that can withstand common road conditions and ensure no damage during driving. The patent pointed out that under normal circumstances, car glass will be broken or broken without too much external force, and sometimes splashing small stones will cause glass damage, which requires replacement of the entire glass, which is not only expensive but also difficult to replace , So Tesla hopes to avoid this from happening.
Under normal circumstances, car glass will be shattered and broken without too much external force, and sometimes even splashing small stones will cause glass damage. In fact, in some cases, the outer layer can resist the generation and expansion of cracks, so it can The glass exhibits durability when a vehicle crashes or is hit by a baseball mistake in a young baseball league. The glass is not only used in Cybertruck, the patent display also shows that there are cars using the glass.
