Tesla’s laser wiper patent has been exposed and will be used with photovoltaics
Tesla’s laser wiper patent has been exposed and will be used with photovoltaics. The patent is a magical windshield Wipers that use laser beams to clear debris from the driver's line of sight. Tesla's patent for laser wipers has been exposed and will be used with photovoltaics. Tesla laser wiper patent exposed, will be used with photovoltaics 1
As early as 2019, Tesla applied for a new patent that can use a vehicle-mounted laser system to clean the front and rear windshields and The camera can even remove debris from the solar panel on the roof of the car, so it is also called a "laser wiper".
Recently, this brand-new technology was finally officially announced by the US Patent Office. However, it should be noted that it cannot remove water from the glass on rainy days, and it cannot replace the traditional wiper.
Tesla described in the published documents that this patent is for a vehicle cleaning system that can generate a laser beam to illuminate the beam optical assembly of the vehicle glass area and detect the accumulation in the vehicle glass area. A debris detection circuit for debris in the area, and a control circuit.
While its primary use is pulsed laser cleaning of debris that has accumulated on glass in vehicles and photovoltaic modules, the control circuit can also use the laser beam to remove debris that has accumulated on areas of glass.
This feature may be applied to vehicles equipped with solar panels in the future to remove debris from the solar panels to ensure direct sunlight and power generation efficiency.
It is worth noting that this cleaning system is not automatic and requires the driver to manually control the operation, which can also ensure the safety of use to the greatest extent.
Using lasers to clean fallen leaves, which sounds very cool, may really be realized by Tesla. Musk, who is not too fond of "lasers", finally found a very suitable one for it. Work scene. Tesla’s laser wiper patent is exposed and will be used with photovoltaics 2
According to foreign media reports, the U.S. Patent Office (U.S. Patent Office) announced the details of Tesla’s new patent. The patent is for a magical windshield wiper that uses laser beams to clear debris from the driver's line of sight.
In the past, Tesla has come up with many fantastic ideas for windshield wipers, the most interesting of which is its "pulse laser to target debris accumulated on glass products in vehicles and photovoltaic modules." Clean" patent.
Tesla described the patent in published documents as follows: The patent is for a vehicle cleaning system that includes a beam optical component that emits a laser beam to illuminate the vehicle glass area, detects the accumulation of A debris detection circuit for debris in the area, and a control circuit. Among them, the control circuit can calibrate a set of parameters through a laser beam, and the laser beam is emitted by the beam optical assembly based on the detection of accumulated debris in the glass area.
In addition, the control circuit can also control the exposure level of the laser beam on the debris accumulation, and the debris accumulation is based on the parameter calibration of the laser beam, where the exposure level is controlled based on the pulsed laser beam at the calibration rate, And this calibration rate limits the penetration of the laser beam to the thickness of the glass. Not only that, but the control circuit also uses a laser beam to remove debris that accumulates on areas of the glasswork.

Tesla’s flowchart describing the patent process is relatively simple and shows clearing a solar (000591) battery Uses of board fragments. The use of this patented laser cleaning assembly is divided into five steps:
Detection of accumulated debris on areas of glass products installed on vehicles;
Based on the detection of accumulated debris on areas of glass products. Detection, calibration of a set of parameters associated with a laser beam emitted from a beam optics assembly;
Controlling the level of exposure of a laser beam to accumulated detection debris on a glass article based on calibration of a set of parameters associated with the laser beam ;
Illuminating the area of ??the glass article associated with the detected debris with a laser beam;
Removing the detected debris accumulated in the area by the laser beam.
The system does not appear to be fully automatic.
In this system, the driver can control the laser via a touch screen, joystick or other media to communicate with the different operating components of the cleaning equipment.
While the patent may seem outlandish, the idea of ??using lasers to clear windshields is very Tesla-esque. In the future, if this new laser patent is applied to Tesla vehicles, it can reduce the minimum maintenance costs for car owners. Tesla laser wiper patent exposed, will be used with photovoltaics 3
Tesla has always been interested in some unique designs and revolutionary car ideas. Over the years, Tesla has Several glass wiper designs and ideas have been studied, from a single wiper system for the roadster of the next generation sports car (using electromagnetic linear actuators to remove moisture from the windshield) to the huge wiper on the Cybertruck pickup truck, and finally this car Cybertruck wiperless design~
Among them, what attracts the most attention is a new patent filed by Tesla in 2019, which is called "laser wiper".
p>This wiper can use the laser system to clean the front and rear windshields and cameras, and can even remove debris from the roof solar panels. In short, it uses lasers to replace the windshield wipers to clean the debris outside the vehicle. Things!
According to reports, the reason why the Cybertruck pickup truck has no wiper design is because the car may use a "laser wiper", and the patent was approved at the end of 2021. Recently, the United States The Patent Office has announced this patent ~
According to Tesla’s description in the document submitted to the U.S. Patent Office: “This patent is a vehicle cleaning system that can generate laser The system consists of a beam optical assembly that illuminates the vehicle glass area, a debris detection circuit that detects debris accumulating in the area, and a control circuit."~
The system works by including a dust and debris detection system, and an emission The device can attack particles with a pulsed laser beam, but the force will not be strong enough to break the surface of the glass.
However, it should be noted that it cannot remove the water on the glass on rainy days. From this point on It will not replace the traditional wiper!
This feature may first be implemented on solar panel models in the future. It will be used to remove debris on the solar panels to ensure direct sunlight and power generation efficiency. .
It is not yet known which car Tesla’s laser wipers will be used in first, but the illustration in the patent shows the Model S body. Perhaps this laser wiper should be used in the Model S first. Up~
