From 2065438 to September 2009, Tesla registered a brand-new wiper design patent to solve the shortcomings of traditional wiper cleaning, such as dead angle, low efficiency, and the working process will affect the sight of people in the car.
Although the new wiper patent has not yet been applied to various Tesla models on sale, in the near future, maybe we will see this wiper on the brand-new electric pickup truck Cybertruck.
In appearance, this patent is very different from the traditional wiper. It uses a single wiper, but in the introduction of this patent, it describes more details of this wiper: not only the number of wipers has been reduced from two to one, but also the movement mode of wipers has undergone subversive changes. The traditional wiper takes a single point as the axis and moves around a plurality of rotating pairs through a rod system to remove dust and rain on the glass surface, while the brand-new patented wiper moves horizontally to remove stains and rain on the whole window.
Moreover, the driving mode of the new patented wiper is quite different from that of the traditional wiper. In the detailed introduction of the patent, it can be known that this kind of wiper is driven by an electromagnetic slider located below the wiper, rather than a traditional motor. Through the traction of the electromagnetic guide rail and slider at the lower part of the front windshield, the brand-new wiper can slide straight across the whole window. There is no friction between the electromagnetic slide rail and the slider structure itself, and there is no mutual wear and energy loss due to mechanical friction (similar to the principle of magnetic levitation). The wiper only rubs against the window when it is working.
This design not only reduces the energy loss of the whole vehicle motor, but also effectively increases the cruising range of pure electric vehicles. At the same time, this structure also saves the complicated rotating mechanism and motor of the old wiper, and the wiper mechanism is not easy to be damaged.
The traditional design of rotary double wipers has many dead angles on the window in rainy days, but this problem has been solved in front of a brand-new wiper that slides through the window in a straight line. The brand-new design keeps the driver's clear vision in rainy or thunderstorm weather to the maximum extent, and further improves the driving safety factor in rainy days. More importantly, for the automatic driving scheme that relies heavily on the camera, the high-definition field of vision in rainy days helps to greatly improve the reliability of Tesla's automatic driving.
Not only is it powerful, but this wiper can also be rotated and stored near the electromagnetic slide rail under the windshield when it is not working, making the whole vehicle more concise and beautiful.
Of course, the cost of electromagnetic mechanism itself is relatively high, so it may be difficult to equip a large number of models with similar prices, and the maintenance cost in the later period is uncertain. Can such a brand-new wiper, which is beautiful and can clean windows without dead ends, be popularized? Wait and see!
