Wiper blade is a common body accessory, which is mainly used to scrape off the rain on the windshield in rainy days and can also be used to clean the windshield. The power source of wiper blade comes from motor, which is the core of the whole wiper blade system.
abstract
The quality requirements of wiper blade motor are quite high. It adopts DC permanent magnet motor, and the wiper blade motor installed on the windshield is generally integrated with the worm gear and worm mechanism. There are two kinds of wiper blades, one is the traditional intermittent wiper blade, which is the most common wiper blade, and the driver adjusts it according to the rain and line of sight; The other is the rain bead induction type, which is mostly used in mid-to high-end models. A good wiper blade must be heat-resistant, cold-resistant, acid-and alkali-resistant, corrosion-resistant, can fit the windshield, reduce the burden on the motor, have low noise, strong water repellency, be soft and not scratch the windshield, and make your vision clear.
Application mode
Improper use of automobile wiper blades (wiper, wiper blade, wiper blade) will make the wiper blades scrapped or unclean in advance. No matter what kind of wiper, the reasonable use should be:
1, it must be used when it rains. Wiper blades are used to clean the rain on the front windshield. You can't use it without rain, and you can never dry it without water. Because there is no water, the friction resistance will increase, which will damage the rubber scraper and wiper motor! Even if it rains, if it is not enough to start the wiper blade, it should not be scraped. Be sure to wait until there is enough rain on the glass surface. The word "enough" here will not block the driving sight.
2. It is not recommended to use wiper blades to remove dust from the windshield surface. Even if you want to do this, you must also spray glass water at the same time! Don't dry wipe without water. If there are solid things on the windshield, such as the dry feces of birds such as pigeons, don't scrape it directly with a wiper! Please clean the bird droppings manually first. These hard things (others, such as gravel with larger particles) can easily cause local damage to the thin sheets of the rain wiper, resulting in the wiper not being able to clean the rain.
3. The premature scrapping of some wiper blades is directly related to improper car washing. There is a thin oil film on the glass surface before the car leaves the factory. If you don't pay attention to the front windshield when washing the car, the oil film on the surface will be washed away, which will not be conducive to the downward flow of rainwater for a while, which will lead to the rainwater easily stopping on the glass surface, and will increase the friction resistance between the rubber and the glass surface. This is also the reason why the wiper blade suddenly stopped because it couldn't scrape. If the wiper blade does not move, the motor will continue to run, which will easily lead to the motor burning out.
4. If you can scrape in slow gear, you don't need to scrape in fast gear. When using the wiper, there is a fast gear and a slow gear. If you scrape quickly, you will use it more frequently and wipe it more times, and the service life of the wiper blade will be reduced accordingly. Wiper blades can be replaced in half. The wiper in front of the driver's seat has the highest usage rate, with higher frequency, wider range, greater friction loss, and the owner's line of sight is also very important, so this wiper is replaced more frequently. The number of replacement of the wiper corresponding to the co-pilot position can be relatively small.
5. Be careful not to damage the wiper blade. When lifting the wiper blade during car washing and daily ash shooting, try to move the heel of the wiper blade backwards and put it back gently when putting it away. Don't bounce the wiper blade back.
6, in addition to the above, but also pay attention to the cleaning of the wiper blade itself. If dust is attached, it will scratch the glass and cause self-injury. Try not to be exposed to high temperature, frost, dust and other conditions. High temperature and frost will accelerate the aging of wiper blades, and dust will cause bad scraping environment and easily damage wiper blades. It snows at night in winter, and it is forbidden to use wiper blades to clear the snow on the glass in the morning.
