Due to the limitation of early glass manufacturing technology, the earliest vehicles used flat front windshield. But the impact of stones or larger insects makes them very fragile, especially at high speed, so they are gradually abandoned. However, Cybertruck has no such problem. Although the glass of electric pickup truck is very flat, the use of Tesla's so-called "armored glass" can avoid the situation of early car glass.
This new type of wiper has a unique design because it is driven by an electromagnetic moving block sliding on the guide rail. This is somewhat similar to the working principle of magnetic levitation. The moving block moves from one side of the windshield to the other like a magnetic levitation. The wiper sticks to the glass and becomes the only source of friction, which is its main advantage.
Without the traditional swing arm structure, it can bring less friction, and the power consumption of such a wiper will also be reduced. Any energy-saving method of electric vehicles will affect the endurance. In addition, Tesla has another purpose, that is, the cooperation between the new wiper and the automatic driving system can ensure that the front windshield has a better view than the traditional wiper.
Although it has not been determined whether Tesla will land this patent quickly, Cybertruck's flat windshield is very suitable for this technology. If Tesla can make magnetic suspension wipers on any of its vehicles without reliability or quality problems, it will definitely be another progress in the field of automotive technology.
