Title:
A WINDSCREEN WIPER AND A MOTOR VEHICLE COMPRISING SUCH WINDSCREEN WIPER
Document Type and Number:
WIPO Patent Application WO/2019/148360
Kind Code:
A1
Abstract:
A windscreen wiper for a motor vehicle, which includes a wiper blade and a driving system, the driving system comprises a wiper motor for driving the wiper blade to rotate. The driving system further comprises: a wheel plate (1) driven by the wiper motor to rotate about a central axis of rotation of the wheel plate (1), an angular position of the wheel plate (1) is associated with an angular position of the wiper blade; a parking cam (2) disposed on the wheel; two parking contact springs (4.1, 4.2), each carrying a parking electrode pressing against the surface of the wheel plate (1) under a resilient bias of the parking contact spring (4.1, 4.2), a track slid by the parking electrode on the wheel plate (1) during the rotation of the wheel plate (1) is called a parking trace. The distance between the parking electrodes of the two parking contact springs (4.1, 4.2) and the central rotation axis of the wheel plate (1) is substantially equal to each other, so that the parking traces of the parking electrodes generally coincide with each other. The parking cam (2) is a single-trace cam consisting of only one arc-segment, and the parking trace substantially follows a center arc of the parking cam (2). A motor vehicle comprising such a windscreen wiper is also provided. By using a single-trace cam (2), the windscreen wiper is able to achieve the wiper parking function in a compact and cost-effective manner.
