Problems solved by technology

However, conventional cleaning devices of the known glass or headlight cleaning device type as well as known camera cleaning devices are either of complex construction and at the same time require a large installation space in order to be satisfactorily installed in the prescribed installation position, or have protruding nozzles, which can result in an incongruous appearance

Embodiment Construction

[0028] In all top views, the reflector is shown in a completely transparent manner and only by its outer outline, in order to more clearly show the elements located below the reflector.

[0029] figure 1 with figure 2

[0030] As an example of a preferred embodiment, figure 1 with figure 2 A light detection and localization device 1 or LiDAR designed according to the invention is shown in a very simplified manner.

[0031] Inside the LiDAR housing 5, there are two functional units determined by the function and separated in space—the functional unit F 2 and the first functional unit F 1 , where the functional unit F 2 is designed as a transmitting unit for transmitting a laser beam, the first functional unit F 1 Designed as a receiver unit for detecting reflected laser beams. Each functional unit F 1 , F 2 each have their own optical axis O passing through the transparent cover plate 4 1 or O 2 . The cover plate 4 basically serves to protect the functional unit ...

Abstract

The invention relates to an optical or optoelectronic device (1) comprising at least one transparent cover (4) and comprising a cleaning device (2) for cleaning the surface (3) of the cover (4) usinga fluid cleaning agent. In order to effectively clean such a device, in particular a LiDAR device, without the external appearance being impaired by visible components of a cleaning device, the invention proposes directing the jet (8) of cleaning agent against a reflector (9), which is at least temporarily or permanently arranged so as to be at a distance from the outlet opening (7) and the surface (3) and oriented such that the jet (8) of cleaning agent is reflected by the reflector (9) and is deflected in the form of at least one spray jet (10) onto the surface (3).

Description

technical field [0001] The invention relates to an optical or optoelectronic device with a preferably integrally arranged cleaning device for cleaning a transparent cover of the optical or optoelectronic device, in particular for devices arranged in an exterior area on a vehicle , Light-transmissive cover for laser-based measuring devices. Background technique [0002] The use of assistance systems with optical and / or photoelectric sensors in motor vehicles is already known, which assists the vehicle user when driving the vehicle or enables driver-independent automatic driving. [0003] For example, it is known to use so-called LiDAR or LaDAR (Light Detection and Localization / Laser Detection and Localization) devices to optically observe the surroundings of the vehicle. Systems of this type are installed on the vehicle in the outer area and have at least one transmitter unit which transmits a laser beam and at least one receiver unit which detects the laser beam reflected b...
