Embodiment Construction

[0035] In the drawings, components or devices with the same or similar functions or structures are denoted by the same reference numerals unless otherwise specified.

[0036] A wiper system according to the present invention is equipped to a vehicle for removing dirt, fallen leaves, road debris, deposits and the like from the windshield and for keeping the driver's field of vision clear.

[0037] figure 1 and figure 2 Two types of loose link wiper systems (Loose Link Wiper Systems) 100 that are common today are shown.

[0038] The wiper system 100 for a vehicle generally includes a drive assembly 12 , also referred to in the art as a motor assembly, for powering the wiper system 100 . The drive assembly 12 includes a motor 18 and a reduction mechanism 14 . The motor 18 is usually a permanent magnet DC motor, and the reduction mechanism 14 is a commonly used reduction mechanism known in the art. The motor 18 and the reduction mechanism 14 are respectively fixed on the veh...

Abstract

The invention relates to a wiper system for a vehicle comprising a pivot housing (52) defining a shaft hole which extends in an axial direction, a pivot shaft (42) for supporting a wiper arm (10) of the wiper system being rotatably mounted in the shaft hole; and a fixed element (51) configured to be fixed to a body of the vehicle; wherein the fixed element (51) and the pivot housing (52) are detachably coupled to each other by means of a releasable locking structure (82, 70), the locking structure (82, 70)being in a locked state and thus the fixed element (51) and the pivot housing (52) being coupled together in normal use, and the locking structure (82, 70) being unlocked and thus the fixed element (51) and the pivot housing (52) being decoupled from each other so as to allow the pivot shaft (42) to be moved towards the body of the vehicle when an axial load or an axial component of the load exceeding a certain predefined threshold value is applied to the pivot shaft (42).

Description

technical field [0001] The invention relates to a wiper system for a vehicle comprising a fixing element and a bushing seat configured for detachable engagement with the bushing seat. Background technique [0002] As countries pay more and more attention to pedestrian safety protection, there are more and more strict regulations on pedestrian impact protection. For example, when a pedestrian is hit by a vehicle, it will be very serious especially if the pedestrian's head hits the wiper system of the vehicle, which will cause the pedestrian's head to be injured. [0003] A wiper system for a vehicle generally includes a motor assembly disposed on one side or between a driver's side and a passenger's side; a link assembly connected to the motor assembly; and a wiper arm assembly, which includes a A wiper blade that swings back and forth on the windshield. In particular, the connecting rod assembly includes a support shaft and a bushing seat installed therein, and the bushing...
