Abstract
An optical device 10 for a vehicle comprises an optical element 14 and protective mechanism 20, which are both at least partially encased by a housing 12. A clear tape 22, part of the protective mechanism and moveably mounted within the housing, is exposed by the housing to cover the side of the optical element facing away from the housing. The optical element may be a source of light or a camera 16, whereby the lens 18 is blocked by the transparent film. The housing may include a template 38 equipped to clean part of the light transmitting tape to prevent unwanted foreign matter (dirt, dust, water) entering the housing. The protective mechanism may comprise automatically rotating spools 24, 26, one from which the transparent foil is unrolled and a second which it is wound onto; the rollers may be rotatable around the same or different axis.
Description
Optical device for a vehicle The invention relates to an optical device according to the preamble of patent claim 1.
Such a device is disclosed in the DE 10 201 3 223 275 A1, wherein a camera is disposed in a handle module of a vehicle door with the handle module optionally featuring a segmented housing. A lens of said camera can either be exposed or protected by a protective element with a spraying nozzle module being provided to clean the outside surface of the lens or the protective element, respectively, by spraying on it a cleaning liquid.
It is a first object of the present invention to provide an optical device equipped with a mechanism to firstly protect a sensitive optical element of the optical device and to secondly provide a means to clean a path of rays between the immediate surroundings of the optical device and the optical element. It is a second objective to provide a method for running a corresponding optical device.
These objects are solved by an optical device having the features of patent claim 1 and a method having the features of patent claim 9. Advantageous embodiments with expedient developments are indicated in the other patent claims.
To provide an optical device that features a protective mechanism to firstly protect a sensitive optical element of the optical device and to secondly provide a means to clean or clear a path of rays between the immediate surroundings of the optical device and the optical element, it is provided that the protective mechanism comprises a transparent tape that is movably mounted inside the housing and that forms the exposed part of the protective mechanism. This means that the -at least potentially -sensitive optical element is protected by the transparent tape that is disposed between it and the immediate surroundings or any outside influences. By having the transparent tape mounted movably, the part that is protecting the optical element at any one time can be moved out of the path of rays while being replaced with another part or section of the transparent tape that was previously disposed inside the housing and thus not exposed.
In this manner, dirt or other foreign matter disposed or accumulated on the exposed part of the transparent tape -and thereby blocking the path of rays or impairing the intended proper functioning of the optical device or parts thereof -can be moved or transported out of the path of rays together with the respective part of the transparent tape. Moving the transparent tape effectively also moves any foreign matter like for example dirt of water that is sticking to it. Thus a free path of rays can be restored while keeping the optical element protected at all times.
It is especially advantageous if the transparent tape can be moved automatically.
It is to be noted that within the meaning of the present invention, the scope of the terms "optical", "transparent" and "light" is not limited to the visible spectrum but can pertain to any part or parts of the electromagnetic spectrum intended to be used with or by the optical device. This can for example include applications in infrared (IR) wavelengths.
In an advantageous embodiment of the invention the optical element is a camera with a lens that is protected by the protective mechanism. It is obvious that it is advantageous for the lens of a camera to be protected in order to not sustain any marks or scratches that would impair its performance. It is also obviously advantageous to be able to restore a free path of rays in front of the lens in order for it to have a free field of view.
In another advantageous embodiment of the invention the optical element is or comprises a source of light. Such a source of light can for example comprise an LED (light-emitting diode), any type of light bulb, or a laser. It can also comprise a lens. Here the same advantages apply as described above regarding a camera.
In a further advantageous embodiment of the invention the housing comprises a template through which the exposed part of the protective mechanism is exposed with the template being equipped to clean at least part of the transparent tape. The template can be used to guide the transparent tape and ensure proper position and alignment. It can also be used to clean the tape as it is moved so as to prevent any dirt or other foreign matter like excessive amounts of water sticking to the tape from entering the housing. To achieve this, the template can for example comprise a brush or an edge or scrape along which the tape is guide before or while entering or re-entering the housing.
Preferably the protective mechanism comprises a rotating spool. Such a spool could preferably be disposed inside the housing and used to dispense and/or collect the transparent tape. A spool is easy and cheap to manufacture and provides a very efficient, space-saving means to store tape and can also be used to provide and control the desired amount of tension.
In an advantageous embodiment of the invention the protective mechanism comprises a first spool from which the transparent tape is unspooled and a second spool onto which the transparent tape is spooled. This means that the first spool provides clean, unused tape which has not been exposed yet to replace an exposed part or section of tape when it is moved. The second spool on the other hand collects the used and previously exposed parts or sections of the tape after they have been moved from in front of the optical element back inside the housing. It is to be understood that both spools are preferably disposed inside the housing. Thus it is possible to easily and effectively control the moving of the tape while simultaneously keeping it taut. Another advantage is that spools provide a means of storing the tape that is very efficient in terms of manufacturing costs and space requirements and also eliminates any problems tangling of the tape.
In a further advantageous embodiment of the invention the first spool and the second spool are rotatable around the same axis. This can further reduce the complexity, the space requirements and the manufacturing costs of the mechanism.
In a further advantageous embodiment of the invention the provided spool or spools can be automatically rotated. For this purpose for example an electric motor, a linear motor ratchet mechanism, or a loaded spring with a release mechanism can be provided. Preferably the mechanism to automatically rotate the spool or spools and thereby move the transparent tape is disposed inside the housing and designed with a maintenance-free operation time at least equal to the expected lifetime of the supply of tape. An automatic operation of the mechanism has clear advantages since it can enable unsupervised use or use in not easily accessible places or dangerous situations.
To provide a method for running an optical device equipped with a mechanism to firstly protect a sensitive optical element of the optical device and to secondly provide a means to clean a path of rays between the immediate surroundings of the optical device and the optical element, it is provided that a transparent tape forming the exposed part of the protective mechanism is movably mounted inside the housing and moved in such a way that the exposed part of the transparent tape is replaced by a previously not exposed part of the transparent tape.
The above-mentioned features and embodiments and their corresponding advantages analogously also apply to the method according to the present invention and vice versa.
Further advantages, features, and details of the invention derive from the following description of preferred embodiments as well as from the drawings. The features and feature combinations previously mentioned in the description as well as the features and feature combinations mentioned in the following description of the figures and/or shown in the figures alone can be employed not only in the respectively indicated combination but also in other combination or taken alone without leaving the scope of the invention.
The drawings show in: Fig. 1 a schematic sectioned top view of an optical device; in Fig. 2 a schematic sectioned side view of an optical device similar to the one shown in Fig. 1; and in Fig. 3 a schematic sectioned top view of another embodiment of an optical device.
In the figures the same reference signs indicate the same elements or elements having the same function.
Fig. 1 shows in a schematic sectioned top view an optical device 10 with a housing 12. Disposed inside the housing 12 are an optical element 14, which comprises a camera 16 with a lens 18, and a protective mechanism 20. The protective mechanism 20 comprises a transparent tape 22, a clean tape spool 24, a used tape spool 26 and a diverting pulley 28 with the clean tape spool 24 functioning as a reserve and supply for the transparent tape 22 and the used tape spool 26 collecting it. Booth spools 24, 26 are rotatable and can either have the same or different axis of rotation. It is to be noted that only a schematic view is depicted and any real embodiment might include additional parts.
In an opening 44 (Fig. 2) of the housing 12 and disposed just in front of the camera 16 and the lens 18, respectively, and therefore between the immediate surroundings of the housing 12 and the lens 18 there is a template 38. The transparent tape 22 is guided through this template 38 so as to cover the lens 18 -or at least part of it -and protect it from outside influences. Although the camera 16 and the lens 18, respectively, are presently disposed directly next to the template 38, this is not necessary and a positioning further inside the housing 12 is also possible. In this context the exposed part 34 of the protective mechanism 20 being disposed on a side of the optical element 14 facing away from the housing 12 means that any path of rays originating outside of the housing 12 passes through the opening 44 (Fig. 2) of the template 38 and the exposed part 34 of the transparent tape 22 before reaching the lens 18 or any other part of the optical element 14.
It is preferred to have any opening 44 (Fig. 2) of the template 38 covered or blocked by the transparent tape 22 in order to prevent any unwanted foreign matter from dust particles and dirt to water from entering the housing 12 through an opening 44 (Fig. 2) of the template 38 as far as possible.
For any optical device and especially for those intended for outdoor use, impairment of the optical performance through foreign matter like dust, dirt, water, etc. (simply referred to as dirt for short from here on out) always represents a problem. Previous solutions typical use some sort of cleaning liquid that is sprayed on an outside surface. These solutions have their own problems though. The spray nozzles for example can be prone to clogging through either dirt or freezing of the cleaning liquid, the used cleaning liquid has to be channelled away, and the supply of cleaning liquid has to be refilled regularly, thus requiring maintenance. Also the cleaning liquid itself can potentially hinder optimal optical performance if droplets or any residue remain on the exposed surface. Alternative solutions include blowing a stream of air or gas on or over the exposed surface. This approach, however, can not always reliably clean off all types of contaminations and can be unfavourably noisy.
In order to avoid these problems the present invention does not make use of any liquid or fluid or nozzle at all. Because of this, the present invention has the benefits and advantages of not needing maintenance to resupply and cleaning liquid or unclog nozzles, and of having no dripping liquids that can build up or drain to other systems and devices where they could potentially cause contamination and/or damage. Furthermore the present invention can operate essentially silent.
Rather than exposing a fixed optical element like the lens 18 to outside influences and thereby to potential contamination, the outermost surface of the optical device 10 in the path of rays between the surroundings and the optical element is formed by a small, exposed part 34 of the transparent tape 22 in the area of the opening 44 (Fig. 2) of the template 38. Since the transparent tape 22 is movably mounted, it can be moved in such a way that the exposed part 34 gets replaced by a fresh, unused, and clean part 32 of the transparent tape 22, thereby restoring optimal optical performance of the optical device 10.
If the exposed part 34 gets contaminated or dirty, the impairment of the optical performance caused by the contamination can be detected either by a user or automatically for example by a video information processor detecting an unclear picture. The spools 24 and 26 are then rotated, whereby the transparent tape 22 is moved. The direction of movement is indicated in Fig. 1 by arrows 30a and 30b. The transparent tape 22 runs from the clean tape spool 24 to the template 38, where it is routed across or in front of the lens 18, and on to the diverting pulley 28, where its direction is changed. From there its runs to the used tape spool 26 where it is collected. In this manner, a clean section or part 32 of the transparent tape 22 gets unspooled from the clean tape spool 24 and moved in front of the lens 18 while the exposed section or part 34 is moved away from the lens 18 and back into an inside 40 of the housing 12. Previously used sections or parts 36 of the transparent tape 22 are spooled onto the used tape spool 26.
Fig. 2 shows a schematic sectioned side view of an optical device 10 that -very similar to the one shown in Fig. 1 -comprises the housing 12 with the inside 40, the template 38 with an opening 44, the lens 18 disposed inside of the housing 12 and behind the template 38, and the protective mechanism 20. It can be seen that the transparent tape runs slightly tilted in reference to the top and bottom sides of the housing 12 in order to avoid any collision or conflict between the clean tape spool 24 and the used tape spool 26.
Depending on the size of the lens 18 and the exposed part 34 it can be enough to move the transparent tape 22 in increments of a few millimetres, for example 3 millimetres. In any case it should be enough to move the tape by an amount of length equal or similar to the diameter of the lens. The width of the transparent tape 22 should obviously be chosen to big enough to cover the lens 18 or other optical element to be protected in the corresponding direction. For a lens 18 with a diameter of about three millimetres a transparent tape 22 with a width of three to five millimetres can be sufficient.
Tape spools known from typical audio cassettes can for example hold up to 85 meters of tape in a housing that is small enough to be used in many different applications. For the present invention it is proposed to for example use a supply or spool 24 of 50 metres of transparent tape 22. This equates to a lifetime of 15 years with three movements of three millimetres each every day. This shows that the present invention can be used without maintenance or refilling for the expected lifetime of a vehicle.
It is especially advantageous to provide a means of at least roughly cleaning the transparent tape 22 and in particular the exposed part 34 before or while it is moved back inside the housing 12. Such a means can for example be provided in the form of a brush or scrape along at least part of the opening 44. When the transparent tape 22 is moved it can then be pushed against or scraped along the corresponding means to remove at least any coarse dirt and/or at least some water if there is any and preventing it from entering the housing 12. This ensures that there is no build-up of foreign matter inside the housing 12 and the supply of clean transparent tape 22 does not get contaminated and thereby also ensures that the protective mechanism 20 -and by extension the optical device 10 -is highly reliable and free of maintenance.
The purpose of said means to clean the transparent tape 22 can further be supported by using a variety of transparent tape 22 that has a very smooth surface and/or low adhesion.
Fig. 3 shows another example of an optical device 10 in a schematic sectioned top view. It features essentially the same components as the examples shown in Figs. 1 and 2 as indicated by corresponding reference signs. Additionally some exemplary idler pulleys 48 are shown that are used to guide the transparent tape 22 inside the housing 12 with the direction of motion of the transparent tape 22 being indicated by arrows 46a and 46b.
Also shown is a turning mechanism 50 in form of a simple ratchet mechanism comprising an electromagnet 52, a toothed rod 54 attached thereto and corresponding teeth 56 disposed on an outside rim of a wheel or disk. The latter can be attached to the same axis as one or both of the clean tape spool 24 and the used tape spool 26. One way such a mechanism 50 could work is that the toothed rod 54 can be moved back and forth along its main extent and also with its toothed end moving back and forth along a curved path so that its tooth moves in and out of the area of the teeth 56. This way the toothed wheel or disk could be rotated by essentially grabbing one of the teeth 56 with the toothed rod 54 and pulling it back in the direction of the electromagnet 52, then moving the toothed end of the rod 54 out of the area of the teeth 56 and back out in the direction away from the electromagnet 52 to grab another one of the teeth 56. There are of course many other and different ways for automatically rotating the spools 24, 26 and thereby moving the transparent tape 22.
Instead of or additionally to the camera 16 a source of light can be placed inside the housing 12 and behind the exposed part 34 of the transparent tape 22. Such a source of light can for example be a simple light bulb or lamp, an LED, or a laser which can be provided for illuminating an area in front of the camera 16 to enable it to get a better picture. The source of light can also be used to provide illumination for other systems or devices that are separate from the optical device 10. As mentioned above the term light in this sense is not limited to visible light but can include or refer to other parts of the electromagnetic spectrum like, in particular, infrared wavelengths.
