Front windshield wiper of automobile

Abstract

The invention relates to a front windshield wiper of an automobile, which comprises a driving motor, a transmission mechanism, a wiping sheet and a control device as well as two pairs of curved guiding sliding rails respectively arranged at two side edges of front windshield glass, wherein each sliding rail comprises a sliding rail seat and a sliding device which can do vertical reciprocating motion in the sliding rail seat and has a motion trail approximately identical to the curve of the side edge of the corresponding front windshield glass; and the wiping sheet has a telescopic structure, and two ends of the wiping sheet are fixed on the sliding devices at the corresponding side. The wiping sheet is horizontally arranged on the front windshield glass and can do vertical reciprocating motion, the wiping area is large and the visual interference is small; only a small part of the front windshield wiper is exposed out of an automobile body, the performance for protecting pedestrian is better, the arrangement direction of the exposed part approaches to the direction of the driving, and the wind resistance and the wind noise are not easy to generate.

Description

technical field [0001] The invention relates to an automobile component, in particular to an automobile front windshield wiper. Background technique [0002] At present, the front windshield wiper devices of automobiles that are routinely used mostly wipe the front windshield glass through the swing of the wiper blades. There are several problems in this type of wiper that have been difficult to solve: 1. The wiping area is small; The wiping method of sweeping blades will inevitably cause the front windshield to be wiped only in a small area, and it is difficult to achieve comprehensive wiping, which limits the driver's vision to the front and makes it difficult to fully control the road conditions. Therefore, the safety of vehicle operation is reduced. [0003] 2. The pedestrian protection performance is not high enough; the rotating shaft is arranged in the area between the machine cover and the front windshield. According to the requirements of U-NCAP and the pedestria...

[0002] At present, the front windshield wiper devices of automobiles that are routinely used mostly wipe the front windshield glass through the swing of the wiper blades. There are several problems in this type of wiper that have been difficult to solve: 1. The wiping area is small; The wiping method of sweeping blades will inevitably cause the front windshield to be wiped only in a small area, and it is difficult to achieve comprehensive wiping, which limits the driver's vision to the front and makes it difficult to fully control the road conditions. Therefore, the safety of the vehicle operation is reduced

[0003] 2. The pedestrian protection performance is not high enough; the rotating shaft is arranged in the area between the machine cover and the front windshield. According to the requirements of U-NCAP and the pedestrian protection regulations that will be implemented in China, the head injury value at the rotating shaft position is obviously greater than that at other
