Description

Technical Field

[0001] The utility model relates to the technical field of wiper motors, in particular to a housing of a wiper motor. Background Art

[0002] A windshield wiper is a simple tool used to clean the windshield of a motor vehicle to prevent rain and other debris from obstructing vision. Since Karl Friedrich Benz invented the first automobile in Germany in 1885 and Henry Ford began mass-producing it in the United States in 1908, no car had a windshield wiper as a safety feature. Then, in 1917, an American named JR Oishei accidentally struck a teenager on a bicycle while driving on a rainy night in Buffalo, New York. To prevent such accidents from happening again, he invented a manually operated windshield wiper with a grooved rubber strip on a metal rod. He manufactured and sold it through his company, TRICO (Tri-Continental Corporation, as the telegraph abbreviation is known). However, manually operating the wipers while driving was dangerous in manual transmission cars at the time. So, he developed a pump-operated wiper that was driven by the car's engine speed. However, the wipers moved according to the car's speed, and would stop when the car was stuck in traffic or stopped. Later, in 1917, he successfully combined the wiper rod and motor, which became the ancestor of modern wipers.

[0003] The application number is CN201320755484.1, which discloses a housing for a wiper motor, including a shell, wherein the shell is composed of a stamped outer shell and a stamped inner shell, the inner shell is fixedly arranged in the outer shell, and two fixing feet for fixing magnetic tiles are fixedly provided on the surface of the inner shell, and the fixing feet are symmetrically arranged along the center line. The utility model improves the parts originally formed by die casting, realizes the improvement of the precision stamping process, greatly improves the accuracy and performance of the product, and greatly improves the life of the product; and after optimizing the structure of the product, saves the number of product assembly components, optimizes the manufacturing process of the product, and improves the efficiency of product production.

[0004] Although the above-mentioned utility model has improved the parts originally formed by die-casting and achieved the improvement of precision stamping process, the accuracy and performance of the product have been greatly improved, and the life of the product has also been greatly improved; and after optimizing the structure of the product, the number of product assembly parts has been saved, the manufacturing process of the product has been optimized, and the efficiency of product production has been improved, but there is a shortcoming that when the device is in use, the installation method of the wiper plate on the front side is relatively simple and traditional, which makes it somewhat loose when connected.

[0005] Therefore, it is necessary to replace the connection method in the device with the current connection component, which can provide a certain degree of connection convenience when using the device. Compared with the spiral connection method, it has more stable fixation, simple installation, and saves time and effort. Utility Model Content
