Windscreen wiper and vehicle

Abstract

The invention discloses a windscreen wiper and a vehicle. The windscreen wiper comprises a motor (10), a connecting rod mechanism (20) and a wiping arm (30), wherein the connecting rod mechanism (20) is connected between the motor (10) and the wiping arm (30) for transferring the power of the motor (10) to the wiping arm (30). The windscreen wiper is characterized in that the connecting rod mechanism (20) is a multi-rod mechanism. The vehicle comprises the windscreen wiper. In the windscreen wiper disclosed by the invention, as the connecting rod mechanism (20) is the multi-rod mechanism, compared with a traditional four-rod mechanism, the multi-rod mechanism has more connecting rods, and the torque required to be transferred by each connecting rod is reduced under the condition of definite load. Therefore, force arms of all the connecting rods can be shortened, that is, the lengths of all the connecting rods can be shortened, so that the mounting space and the moving space of the connecting rod mechanism (20) can be reduced, and the windscreen wiper is convenient to arrange.

Description

technical field [0001] The present invention relates to a vehicle trim, in particular to a windshield wiper, and also to a vehicle with the windshield wiper. Background technique [0002] With the development of modern automobile technology, more and more attention has been paid to miniaturization and light weight. In some small cars, the wiper generally adopts a single scraper arm structure, that is, there is only one scraper arm and wiper blade. However, in order to meet the requirements of the wiper area regulations, the length of the wiper blade must be designed to be large enough, and the load carried by the wiper is relatively large. Traditional wipers generally use a four-bar linkage mechanism, and the crank and connecting rod parts are generally longer. This mechanism inevitably requires a larger car body installation space, and also needs to reserve enough movement space to make the wiper on a small car. design is more difficult.

AI Technical Summary

Problems solved by technology

like figure 2 As shown, the single wiper arm wiper uses a wiper arm 30 and a wiper blade 50 to run on the windshield 90 around a rotating shaft 304 arranged in a four-bar linkage mechanism. This structure has only one rotating shaft 304, and the blade 50 The wiping radius is always consistent, resulting in the same running track of the wiper blade 50. When the wiper blade 50 scrapes to the right side of the windshield 90, a large part of the area under the wiper blade 50 cannot be scraped, resulting in a small wiping area, which affects driving. line of sight
