Embodiment Construction

[0041] In the following description, the terms "longitudinal", "transverse" and "vertical" refer to the orientation of the telescoping cleaning device according to the invention. The longitudinal direction corresponds to the deployment direction of the movable piston of the telescoping cleaning device, which is parallel to the longitudinal axis L of the coordinate axis system L, V, T shown in the figures. The transverse direction corresponds to the direction parallel to the main transverse extension axis of the wiper blade of the telescoping cleaning device, which transverse direction is parallel to the transverse axis T of the coordinate axis system L, V, T, and which transverse axis T is perpendicular to the longitudinal axis L. Finally, the vertical direction corresponds to the direction parallel to the vertical axis V of the coordinate axis system L, V, T, which is perpendicular to the longitudinal axis L and the transverse axis T of this coordinate axis system L, V, T. T...

Abstract

The present invention relates to a telescopic cleaning device (100) for cleaning a glass surface (300) of a motor vehicle, comprising at least one hollow body (110) and a movable piston (120) configured to slide in the hollow body (110) along a deployment direction (D) between an extended position and a folded position, the movable piston being configured to support a member for cleaning the glass surface, the device being characterised in that it comprises two cleaning members consisting of a member for projecting (140) a cleaning fluid (FN) conveyed through the hollow body (110) and a wiper blade (130), the two cleaning members being rigidly connected to the movable piston.

Description

technical field [0001] The present invention relates to the field of cleaning sensors / transmitters of motor vehicles, and more particularly to cleaning the glass surfaces of optical sensors of optical detection systems of such vehicles. Background technique [0002] More recent motor vehicles are equipped with a collection of driver assistance systems that assist the driver or replace the driver in certain maneuvers. These driver assistance systems are usually triggered by the detection of a signal, whether that signal is optical, electrical or any other type. In the case of systems triggered by an optical signal, the sensor set up to record the signal must be completely clean in order to avoid the system not triggering or triggering at an inopportune time. [0003] It is known practice to clean such sensors with a cleaning product that is sprayed by a spray device. Cleaning products can dissolve dirt on the sensor. However, subsequent drying of the cleaning product leave...
