Sedan windshield wiper capable of changing brushed water area according to rainfall magnitude

Abstract

A sedan windshield wiper capable of changing the brushed water area according to rainfall magnitude belongs to the field of automobile devices. The sedan windshield wiper comprises a first gear, a rack, a second gear, a first rubber bar and plastic main body, a gear shaft, a second rubber bar and plastic main body and a gear switch, wherein the first rubber bar and plastic main body and the second gear are fixed together by the gear shaft; the rack is mounted in the second rubber bar and plastic main body and is respectively meshed with the first gear and the second gear; the gear shaft of the second gear is fixed to the second rubber bar and plastic main body; the gear switch is connected with the first gear by the gear shaft of the first gear. The relative brushed rain diameter of the windshield wiper can be automatically controlled by the gear switch, the brushed area that the windshield wiper is used for brushing rain for a circle is changed, and the rain brushing diameters of different windshield wipers can be selected according to different rainfall.

Description

technical field [0001] The invention relates to a car wiper that can change the brushing area according to the amount of rainfall, and belongs to the field of automobile devices. Specifically, the angle of the two wipers can be changed according to the meshing of the rack and pinion, and the effective diameter of the wiper can be changed, so that there is Realize the function of determining the area brushed by one rotation according to different rainfall. Background technique [0002] Wipers are a necessary auxiliary tool for every car. However, in practical applications, there is only one type of wiper with an invariable diameter, which cannot change the area wiped by the wiper at one time according to the actual rainfall, resulting in waste of resources when the rainfall is small, and cannot meet the task of cleaning accumulated rain when the rainfall is large. Just can solve this problem, realize the reasonable scraping rain of different rainfall. Contents of the inven...

However, in practical applications, there is only one type of wiper with an invariable diameter, which cannot change the area wiped by the wiper at one time according to the actual rainfall, resulting in waste of resources when the rainfall is small, and cannot meet the task of cleaning accumulated rain when the rainfall is large. It can precisely solve this problem and realize the reasonable scraping of different rainfall
