Description

Technical Field

[0001] The utility model relates to the technical field of windshield wipers, in particular to a windshield wiper which is easy to replace and is used for a rail passenger car. Background Art

[0002] Windshield wipers are usually used to clean the front windshields of cars and other motor vehicles. When it rains, the wipers can promptly remove water droplets on the windshield so as not to affect the driver's sight. However, in cold winter, especially in the north, the temperature outside the car is extremely low, resulting in the overall temperature of the windshield being very low, while the temperature of the heater inside the car is high. When the warm and humid air inside the car contacts the windshield, water mist or even frost is immediately formed, affecting the driver's sight. The wipers are on the outside of the windshield and cannot remove the internal water mist. Therefore, the driver can only wipe it off by himself with a towel, etc. However, this action is extremely dangerous during driving, and a traffic accident may occur if one is not careful.

[0003] A new type of wiper is proposed in the patent with the announcement number CN202320210U, which includes a wiper brush head, a soft wiper, a bayonet, a nozzle, a hollow joint, a hose, a wiper brush arm, an exhaust fan, and an air outlet. The heat of the exhaust pipe is transported into the hollow joint 5 through the hose 6 by the exhaust fan 8, and is transported to the wiper brush head 1 through the nozzle 4, and is ejected through the air outlet 9. The wiper brush arm 7 controls the wiper brush head 1 to wipe the glass back and forth. The hot air ejected from the air outlet 9 eliminates the water mist and frost, and the melted water mist and frost are removed by the hot air ejected from the air outlet 9. The soft rag 2 is wiped clean, and several air outlets connected to the inside of the wiper brush head 1 are evenly arranged on the outside of the soft rag 2, and a bayonet 3 is arranged at the center of the rear end of the wiper brush head 1; a hollow joint 5 is arranged at the top of the wiper brush arm 7, and its end is connected to the driving device; a nozzle 4 is arranged on the front side of the hollow joint 5, and a hose 6 is connected to the rear side, and an exhaust fan 8 is connected to the end of the hose 6, and the exhaust fan 8 is connected to the exhaust pipe of the motor vehicle; the wiper brush arm 7 is connected to the wiper brush head 1 through the bayonet 3 and the nozzle 4, but the following problems still exist in this patent:

[0004] It is inconvenient to replace the wiper arm of the existing wiper after use, and the brush piece arranged on the wiper arm is inconvenient to be installed and removed from the wiper arm.

[0005] In view of the above problems, it is necessary to design a windshield wiper for a rail vehicle that is easy to replace, so as to overcome the above problems. Utility Model Content
