Embodiment Construction

[0025] The optical detection system 1 is for example intended to be mounted on the rear of a motor vehicle, for example on a bumper or a license plate (not shown). It can also be mounted, for example, on the side of the vehicle, for example by replacing the side mirrors.

[0026] The optical detection system 1 comprises an optical sensor module 3 , in particular a camera, and a cleaning device 5 for the optics of the optical sensor module 3 .

[0027] An optical sensor module 3, such as a camera module, comprises a housing 7, an optical sensor 9 accommodated in the housing 7, in particular an exposure sensor (schematically drawn in dashed lines), and optics 11, in particular a protective glass 12, arranged on The sensor 9 faces and forms at least part of the wall of the housing 7 .

[0028] The housing 7 seals and tightly surrounds the optical sensor.

[0029] The protective glass 11 can be made of glass or crystal polycarbonate.

[0030] The optical sensor 9 is, for exampl...

Abstract

The invention concerns a cleaning device (5) for an optical sensor (9) module (3) of a motor vehicle comprising a housing (7), an optical sensor (9) housed in the housing (7), characterised in that the cleaning device (5) comprises a cylindrical flange (21) having first snap-fastening members (23) shaped to engage with second snap-fastening members (25) carried by the sensor (9) module (3), the first (23) and second (25) snap-fastening members being configured such that, in the mounted state, the axis of the cylindrical flange (21) merges with the optical axis (A) of the optical sensor (9), and at least one pipe (35; 37) having spray openings (350; 370) is attached to the inner wall (33) of the cylindrical flange (21), the spray openings (350; 370) being turned towards the optical sensor (9).

Description

technical field [0001] The present invention relates to the field of driver assistance, and in particular to optical detection systems, such as cameras, installed on certain vehicles. More specifically, the invention relates to a cleaning device for such an optical detection system, in particular for driving assistance in order to optimize the quality of the information provided to the driver. Background technique [0002] Optical detection system is the term used for any system that includes optical sensors such as cameras, laser sensors (commonly known as LIDARS) or other sensors based on the emission and / or detection of light in the human visible or invisible spectrum, especially in the infrared. [0003] Viewing cameras, especially rear-view cameras, are currently installed in a large number of existing motor vehicles, and they form part of parking assistance systems in particular, which make it easier to park in spaces without turning and detecting what is behind the ve...
