  • the invention has therefore the object to overcome the aforementioned disadvantages of the prior art, in particular the object resides in providing an ambient air purification device which is distinguished in that it can be easily, i.e., even by a technically unskilled end user, and quickly attached to a road vehicle and removed again therefrom.
  • an ambient air purification according to the invention for a road vehicle that is in particular embodied for removing dusts, in particular particulate matter, and/or gases from the ambient air. It comprises at least one filter element and can be arranged in an external region of the road vehicle.
  • the ambient air purification device is configured to be attached by means of a releasable coupling to a rear of a vehicle, wherein the ambient air purification device comprises at least one mating coupling corresponding to a vehicle-side coupling component.
  • a road vehicle in particular passenger car or truck, in particular light truck, in particular driven by an internal combustion engine and/or electric drive, comprising an ambient air purification device that in particular is configured for removing dust, in particular particulate matter, and/or gases from the ambient air, wherein the ambient air purification device comprises at least one filter element and is arranged in an external region of the road vehicle.
  • the ambient air purification device is an ambient air purification device as described above which is fastened at the vehicle rear by means of a releasable coupling, wherein the road vehicle comprises a vehicle-side coupling component which is releasably connected with the corresponding mating coupling of the ambient air purification device.
  • the object is further solved by a filter element of the ambient air purification device according to the invention.
  • Such a selective installation of an ambient air purification device at a road vehicle is of particular interest when, in times of high pollutant load, bans on driving exist in affected regions for road vehicles having net emissions that are too high.
  • the end user could circumvent such a ban on driving by selectively attaching the ambient air purification device to his vehicle.
  • Such an attachment of the ambient air purification device at the rear of the vehicle has several decisive advantages: Firstly, a mechanically strongly loadable element exists in the form of a vehicle-side trailer coupling component; moreover, mounting/demounting is quick and easy due to a single force application point; moreover, due to the spacing of the coupling head from the car body there is no risk that the car body becomes damaged upon mounting/demounting.
  • a filter element@ is to be understood such that it can be embodied as one piece or as multiple parts and may comprise in particular a plurality of filter units, in particular filter bellows and/or filter pockets. Also, a plurality of sub filter elements can be provided which are joined to a filter element.
  • the mating coupling of the ambient air purification device can comprise or consist of a trailer coupling.
  • the trailer coupling can be a mating coupling for a vehicle-side ball mount coupling, which represents the standard in the field of passenger cars.
  • the mating coupling can also comprise a hatchback carrier device which may comprises in particular at least one fastening element, in particular a hook element, a magnetic mating coupling element and/or a suction cup, that is connectable with a vehicle door or vehicle lid, in particular a hatchback.
  • a hatchback carrier device which may comprises in particular at least one fastening element, in particular a hook element, a magnetic mating coupling element and/or a suction cup, that is connectable with a vehicle door or vehicle lid, in particular a hatchback.
  • fastening elements are known in the field of rear carriers, in particular bicycle carriers, and can be also used, due to their attachment at the hatchback, in vehicles without vehicle-side trailer coupling component.
  • an attachment of the ambient air purification device for example, by means of a suitable carrier system, can be realized at the hatchback such that the latter can still be opened with attached ambient air purification device.
  • stronger gas springs and/or a (linear) drive-supported opening mechanism of the hatchback is advantageous.
  • the ambient air purification device according to the invention can be secured at a ferro-magnetic car body component of the road vehicle.
  • a magnetic attachment is advantageously possible particularly quickly; that even heavier loads can be secured reliably thereby has been demonstrated, for example, by magnetic ski carriers.
  • the fastening element can comprise at least one suction cup; even suction cups are suitable for safely attaching an ambient air purification device according to the invention.
  • a vehicle-side coupling component@ in accordance with the last mentioned embodiments is to be interpreted broadly; for example, in case of a magnetic mating coupling element a magnetic car body section functions as a vehicle-side coupling component while in case of a suction cup as a mating coupling element any surface section of the car body, which has a sufficiently minimal roughness, can serve as a vehicle-side coupling component.
  • the afore described arrangement of the ambient air purification device at a trailer coupling provides the advantage that it can be attached and removed by the end user with a few manipulations; it is reversible.
  • the ambient air is momentarily not loaded with particulate matter and/or harmful gases and/or for traveling in low-load regions, on vacation trips etc., he can simply decouple the ambient air purification device while he can simply selectively attach the ambient air purification device again for traveling in highly loaded metropolitan areas and/or zones with bans on driving for high-emission vehicles.
  • the ambient air purification device comprises at least one receiving housing in which the at least one filter element is received.
  • the receiving housing comprises at least one inlet opening and one outlet opening and is in particular connectable by means of the mating coupling to the road vehicle.
  • the receiving housing for example, can comprise a force-absorbing frame, which absorbs the operating forces, as well as a covering hood, which may be embodied to be separately detachable in order to be able to exchange the at least one filter element as easily as possible.
  • the inlet opening(s) can be provided in a mounted state in the intended travel direction at the front and/or laterally, at the top or bottom at the receiving housing.
  • the ambient air purification device comprises at least two filter elements which in transverse vehicle direction are arranged adjacent to each other, in particular at a predetermined spacing between them.
  • the receiving housing can comprise a titanium dioxide-containing coating at its exterior side for photo-catalytic oxidation of NO2 to NO3.
  • each filter element comprises its own housing.
  • the ambient air purification device can comprise at least one flow deflector that is preferably provided at an edge of the ambient air purification device extending in transverse vehicle direction, preferably in the travel direction to the rear.
  • the flow deflector By means of such an arrangement of the flow deflector, it can be achieved advantageously that emissions of vehicle-associated emission sources, such as brakes, exhaust gases and tire abrasion, can be supplied in a targeted fashion to the ambient air purification device.
  • the invention is not limited to an arrangement of the flow deflector at the aforementioned mounting position; other mounting positions such as at a leading, outer or lateral edge extending in vertical vehicle direction are also possible.
  • an impact pressure upstream of the filter element of the ambient air purification device can be increased so that, in a mounting state, an inflow by means of the travel speed can contribute to the flow.
  • flow deflectors are arranged at the leading lateral edges (vertical) of the ambient air purification device as well as at the lower transverse edge (horizontal), wherein it is particularly advantageous when the lower flow deflector extends as close as possible down to the road surface.
  • flow deflector(s) can be provided at a flank of the vehicle where the ambient air purification device according to the invention is mounted, for example, in a longitudinal region that is between the rear axle and the front axle. In this way, a tunnel effect of the undercurrent of the vehicle can be achieved.
  • the flank-side flow deflectors can also be embodied as shroud parts/planking parts or as a part of a lateral underride protection.
  • the flow deflector can be a flow deflector plate that is preferably positioned tilted at an angle relative to the vertical vehicle direction, longitudinal axis or transverse axis.
  • the flow deflector plate can be embodied, for example, as a flow guide plate or shaped rubber part, rubber profile and/or rubber lip; other materials, in particular synthetic materials, are of course also possible, assuming a sufficient mechanical resilience.
  • a switching function of a flow deflector can be provided whereby this may be an adjustable flow guide plate that can be adjusted between various positions in order to influence the air flow guiding action.
  • the flow guide plate is adjustable between an inoperative position and an operative position wherein, in the operative position, the air flow is guided to the filter element in the particulate matter suction device. In the inoperative position, however, the air supply to the filter element can be stopped.
  • the at least one flow deflector can be designed such that in traveling operation the local air pressure in the inlet region of the ambient air purification device is increased and/or is lowered in the outlet region. In this way, the separation performance per travel distance can be improved and passive flow proportions can be achieved (driven by impact pressure).
  • the ambient air purification device comprises at least one pre- or coarse separator which is upstream in flow direction, viewed in travel direction, of the at least one filter element, in particular a separator grid, separator net, baffle plates and/or a preseparator nonwoven.
  • the pre- or coarse separator in particular the separator grid, is connected with the at least one flow deflector.
  • the coarse separator in particular the separator grid, is provided to prevent that foreign matter can pass into the ambient air purification device and damage the filter element.
  • the separator grid can be designed for this purpose as a coarse mesh and can have a mesh size of 1 mm to 4 mm, preferably 6 mm to 8 mm so that only a negligible small additional pressure loss is generated by it.
  • Such grids are available extremely inexpensively, for example, as aluminum expanded metal.
  • the coarse separator fulfills a filtration function and comprises alternatively or additionally a nonwoven layer.
  • a preseparator nonwoven can be arranged in particular at the raw side on the filter element, for example, glued thereto, or can be present at a predefined spacing to the filter element, wherein an arrangement directly on the filter element has the advantage that the preseparator nonwoven can be exchanged together with the filter element during service.
  • the preseparator nonwoven has in addition water-separating and draining properties and is therefore capable of additionally protecting the filter element.
  • the ambient air purification device comprises, upstream of the at least one filter element in flow direction, a water separator for separating rain water and/or splashing water.
  • the water separator can preferably comprise a lamellar separator and/or a hydrophobic, in particular hydrophobically impregnated, separator layer and/or in particular closable flaps or lamellas.
  • the water separator can in particular be switched on or positioned in the flow path as a function of a rain sensor signal and/or windshield wiper signal. In case of closable flaps or lamellas, they can be adjusted depending on the rain sensor signal/windshield wiper signal.
  • the water separator can in particular be arranged upstream or downstream of the pre- or coarse separator.
  • a windshield wiper signal when coupling the ambient air purification device with the road vehicle, can be extracted without problems from a data bus of the vehicle and describes an operating parameter of the windshield wiper (e.g., on/off, wiper speed).
  • an operating parameter of the windshield wiper e.g., on/off, wiper speed
  • tapping of the windshield wiper signal can also be realized differently, for example, purely electrically.
  • the ambient air purification device comprises holding means for the at least one filter element which prevent by form fit a movement of the filter element in travel direction in order to prevent a release of the filter element in case of braking and rear-ending situations.
  • the holding means are preferably configured such that the opening cross section within the holding means is smaller than the cross section of the filter element transverse to the travel direction.
  • the ambient air purification device comprises a drawer mechanism and/or releasable locking connections for mounting the filter element in the ambient air purification device. In this way, an easily serviceable ambient air purification device can be provided.
  • the filter element can be embodied as one piece or as multiple parts and in particular can comprise a plurality of filter units, in particular filter bellows and/or filter pockets. A plurality of sub filter elements can also be provided which are then joined to a filter element.
  • the height of the at least one filter element can be in a range between 100 mm and 600 mm, preferably between 150 mm and 500 mm.
  • the parameters that have the greatest effect on the separation performance of the ambient air purification device are the height of the filter element and the flow resistance of the filter element which is determined significantly by the filter concept but not by the inflow speed. Therefore, a certain minimum height must be observed in order to achieve a satisfactory separation performance.
  • the filter element with an inflow surface of at least 100 mm ⁇ 250 mm, preferably at least 150 mm ⁇ 500 mm.
  • the volume of the at least one filter element amounts to at least 6.5 l, preferably at least 15 l.
  • the net filter surface of the at least one filter element should be at least 3 m 2 , preferably at least 7 m 2 , most preferred at least 15 m 2 .
  • smaller filter surfaces may also be sufficient.
  • the filter element may comprise a plurality of fold stabilization means which in an embodiment with folded filter bellows support the latter and are arranged at a lateral spacing of not more than 150 mm relative to each other.
  • An embodiment of the filter element as a folded filter is preferred due to the reduced pressure loss in comparison to other configurations.
  • Such a support of the filter bellows by fold stabilization means meets two concerns: Firstly, the filter element due to the travel speed, even in the rear region, is subjected to a high impact pressure and, secondly, the filter element is exposed to wet conditions, not only by precipitation but also due to the actions when cleaning the vehicle, for example, with a high pressure cleaner.
  • the aforementioned problems can be elegantly solved by supporting the folds of the filter bellows by fold stabilization means at a maximum spacing of 150 mm so that the filter element survives an inflow at Vmax (in case of direct inflow), e.g. 180 km/h, preferably >200 km/h, without being damaged, as well as that it cannot be damaged by external cleaning actions by high pressure cleaners.
  • Vmax in case of direct inflow
  • a filter element with classic bellows configuration in case of such mechanical action is at risk of compacting of the folds, i.e., a closure of the intermediate fold spaces, which leads to a sudden loss of filter surface and thus immediately causes a corresponding rise of the flow resistance and thus a corresponding drop of volume flow.
  • the range of the lateral spacing of the fold stabilization means in accordance with the invention of not more than 150 mm can advantageously be limited downwardly such that the spacing preferably is greater than 15 mm, preferably greater than 30 mm, because otherwise an unfavorable ratio of filter bellows regions covered by the fold stabilization means and free flow-through regions would be present.
