Description

Technical Field

[0001] The utility model relates to the technical field of motor assemblies, in particular to a waterproof windshield wiper motor assembly. Background Art

[0002] The so-called windshield wiper is a tool used to clean the front glass of a motor vehicle to prevent rain and other dirt from affecting vision. Since the invention of the first car by Karl Friedrich Benz in Germany in 1885 and the mass production of cars by Henry Ford in the United States in 1908, all cars at that time did not have a windshield wiper as a safety device. Later, in 1917, an American named O'Shea was driving on a rainy night in Buffalo, New York, and accidentally hit a teenager riding a bicycle. In order to prevent such accidents from happening again, he invented a windshield wiper with a grooved rubber strip on a metal rod, which was cranked by hand and manufactured and sold through the Trico Company he founded.

[0003] For example, the authorization announcement number "CN201263107Y" is named as a wiper motor assembly. Although the reducer and the connecting rod are directly matched and fixedly connected by setting a positioning pin on the reducer and a positioning hole on the connecting rod, the mounting plate connecting the reducer and the connecting rod is omitted, the mold cost and sheet metal material of the mounting plate are saved, and the welding process of the mounting plate and the connecting rod is saved, so that the integrated wiper motor assembly reduces the cost, can adapt to a smaller installation space, and is easy to install. However, the waterproof device set by the utility model allows rainwater to enter the outer shell of the motor along the through hole. If the outer shell is not sealed tightly, it will enter the inside of the motor, resulting in poor contact of the motor. Utility Model Content
