    [0001] [001] The present invention relates to a device with a winding arrangement and to an arrangement, especially charging station, for contactless energy transmission to an electric vehicle with a winding arrangement.
    [0002] [002] It is generally known that, in a flat winding, turns form a flat arrangement, therefore, they are arranged in a winding area.
    [0003] [003] From WO 2013/000593 A1 a flat coil is known for transmitting energy without contact.
    [0004] [004] The invention therefore has the objective of having a device with a winding arrangement protected.
    [0005] [005] The objective is achieved by the device and the arrangement according to the characteristics of the present invention.
    [0006] [006] Important characteristics in the device with winding arrangement, especially device built in a laminate manner with winding arrangement are that the winding arrangement is housed in a winding support, where the winding support is disposed between a cover part, especially by which the winding support is covered, and a layer of ferrite, which has notches, especially gaps, where the ferrite layer is arranged on a support, especially aluminum support, especially for shielding magnetic exchange fields, which is arranged on a bottom part, where, in the bottom part, support domes are provided, specially integrally formed and / or shaped, which cross the notches of the ferrite layer and touch and / or support the winding support and / or the covering part.
    [0007] [007] It is therefore advantageous that the force of the weight of a vehicle parked on the covering part is deflected from the ferrite layer, thus being passed through the ferrite layer. Because it is driven by the gaps in the ferrite layer.
    [0008] [008] In an advantageous configuration, the bottom part resting on the bottom has a wall thickness or height that increases within the support area on the bottom outside to the middle of the support area, especially in such a way that the part the bottom has a convex shape and water seeps out. It is therefore advantageous that water damage is preventable and, even after water has penetrated or overflowed the bottom, especially when flooding, rapid drainage can be achieved.
    [0009] [009] In an advantageous configuration, the bottom part resting on a flat bottom is executed in the manner of a hill and / or has a curved structure, with the maximum of the curved course being arranged in the middle in the bottom part. It is therefore advantageous that simple fabrication of the bottom part as an injection molded part is possible.
    [0010] [0010] In an advantageous configuration, the bottom part has the shape of a pyramid change. It is therefore advantageous that a simple fabrication of the bottom part is made possible as an injection molded part and / or when production, the ferrite plates can be laid in a simple way on the bottom part, therefore on the pyramid trunk.
    [0011] [0011] In an advantageous configuration, the cover part is joined with the bottom screwed especially by means of bushings joined by positive union and / or force with the bottom, on which the cover part rests. It is therefore advantageous that simple fixing is possible.
    [0012] [0012] In an advantageous configuration, the cover part is tightly joined with the bottom part, insofar as an edge segment, especially, therefore, a crown edge, of the cover part, compresses the bottom part over a continuous region on the outer edge of the bottom part and deforms it. Especially then the bottom part is pressed against the bottom in the region of continuous deformation at the outer edge of the bottom part. It is therefore advantageous that a high protective effect can be obtained in a simple way.
    [0013] [0013] In an advantageous configuration, the winding wire of the winding arrangement is joined by stapling in corresponding recesses. It is therefore advantageous that a simple laying technique is applied to the winding wire and that the winding wire can be retained in position in a simple manner.
    [0014] [0014] In an advantageous configuration, the bottom part has a notch, especially a notch centrally arranged, in which an electronics part is arranged, in which, especially, the winding wire ends of the winding arrangement are electrically connected with connection devices of the electronics part. It is therefore advantageous that the electronics part can be well protected and in a simple way.
    [0015] [0015] In an advantageous configuration, the notches, especially gaps, and support domes are arranged in a regular flat grid structure, especially the grid structure formed of rows parallel to each other, regularly spaced from each other, the distances being within of the respective uniform row and presenting rows as close as possible to each other, respectively, with a lateral displacement, the notches, especially gaps, and support domes being respectively rectangular. It is therefore advantageous for the support domes to concentrate the loading forces on themselves and thus the ferrite layer is protected. The regularity of the grid structure produces, in total, a uniform distribution of force, therefore a uniform discharge of each support dome. Thus, all support domes are loaded as much as possible with equal intensity. In addition, the magnetic flux is barely impeded by the notches.
    [0016] [0016] In an advantageous configuration, the winding arrangements feature crossings of winding wires, which are executed and / or arranged in respective recesses in the support, therefore in the winding support, which rise monotonously from the outer edge to the inside, in a way what water can flow from the inner region to the outer edge. It is therefore advantageous that the risk of electrical short circuits can be avoided.
    [0017] [0017] In an advantageous configuration, the ferrite layer is formed essentially of uniform ferrite plates, especially respectively quadriform ferrite plates, the ferrite plates being arranged in rows arranged parallel to each other, with the rows of ferrite plates directly adjacent to each other a lateral displacement, being especially between two gaps interposed at least two ferrite plates, especially shorter ferrite plates can be used to close the row compared to ferrite plates of the same nature. It is therefore advantageous that simple assembly and optimized edge closure is possible.
    [0018] [0018] In an advantageous configuration, support and bottom part are executed in one piece, therefore, one-piece. It is therefore advantageous that fewer parts are needed.
    [0019] [0019] In an advantageous configuration, the winding arrangement has partial windings, where each turn of a first partial winding is associated with a turn of a second partial winding, wherein between each turn of the first partial winding and the next one to it of the first partial winding is enclosed an intermediate area which is of equal size to the intermediate area encloses between the two respectively associated turns of the second partial winding, where, respectively, the area enclosed by the loop of the first partial winding is equal to the area enclosed by the respectively associated loop of the second partial winding, each turn of the first partial winding having a number of crossings with the associated turn of the second partial winding. It is therefore advantageous that, by means of crossings, the mutually corresponding turns of the partial winding have the same winding area, respectively, and thus the partial windings have the same inductivity. Mutually corresponding turns must then be understood to be those turns of each partial winding, which have the same order number. For example, therefore, the first turn of each partial winding corresponds, therefore, the turns that have the smallest winding area. The two second turns of both partial windings also correspond to each other and have the second smallest rolled area. The last turns of both partial windings are also matched to each other and then have the largest winding area, respectively, with the same area value respectively.
    [0020] [0020] In an advantageous configuration, this intermediate area, therefore, difference in areas, has two portions, the first portion being on the longitudinal sides and the other portion on the transverse sides of the respective loop, especially in a rectangular execution of each loop thus dividing this area difference evenly in the transverse direction and evenly in the longitudinal direction, especially corresponding to the ratio of the portions to the length-to-width ratio of the rectangle. It is therefore advantageous that a uniform division is possible and, thus, a field course as homogeneous as possible throughout the area wrapped by the winding arrangement can be achieved.
    [0021] [0021] In an advantageous configuration, the winding arrangement of the device has partial windings, a turn of a second partial winding is associated with each turn of a first partial winding, being enclosed between each turn of the first partial winding and the next one thereafter of the first partial winding an area, which is of equal size to the area enclosed between both respectively associated turns of the second partial winding, respectively, the area, enclosed by the loop of the first partial winding, is equal to the area enclosed by the respectively associated loop of the second partial winding, especially with each turn of the first partial winding having a number of crossings with the associated turn of the second partial winding. It is, therefore, advantageous that the areas enclosed by the turns associated with each other are equal. This also applies to the turn of each partial winding directly following, therefore respectively closest to the winding. But also the difference in areas between the turn and the turn following it is the same in both partial windings.
    [0022] [0022] In an advantageous configuration, this difference in areas has two portions, the first portion being on the longitudinal sides and the other portion on the transverse sides. In an essentially rectangular execution of each loop, this difference in areas is thus divided evenly in a transverse direction and evenly in a longitudinal direction, which leads to a particularly homogeneous magnetic field course. The portion ratio then corresponds to the length-to-width ratio of the rectangle.
    [0023] [0023] In an advantageous configuration, the winding arrangement has partial windings, a turn of a second partial winding is associated with each turn of a first partial winding, each turn of the first partial winding having a number of crossings with the associated turn of the second partial winding, especially the area, respectively, being wound by the loop of the first partial winding, equal to the area wound by the respectively associated loop of the second partial winding. It is therefore advantageous that, despite the execution as a flat winding, by means of the intersections, the area respectively wound by the partial windings is executable of the same dimension. Thus, the inductivities of the parallel windings that are parallel to each other are of equal size and the currents are the same and, thus, the magnetic field is homogeneous.
    [0024] [0024] A metallic foreign body, which is found in the magnetic field produced by the winding, is heated due to eddy currents and their ohmic losses. The homogeneity of the magnetic field means that the temperature is then independent of the position of the winding areas. Thus, for the transmission of energy to a secondary winding by jumping through the flat winding, a maximum current can be assigned in the winding arrangement, so that in fact a predetermined peak temperature of the foreign body is not exceeded, but a maximum power is transmissible. .
    [0025] [0025] Another advantage in the coil according to the invention is that, due to the symmetrical structure of both partial windings, a difference in position with the central position of an electric vehicle with secondary winding is easily identifiable by the winding arrangement, therefore , a divergence of the position of more intense coupling between winding arrangement and secondary winding, as the respective current is detected in both secondary windings. Because, due to the lag of the secondary coil and primary coil, inductivities are produced, which are of different dimensions in the secondary windings. When, therefore, the vehicle was parked too far ahead, the current in the first primary winding is greater than the current in the secondary winding. When the vehicle was parked too far back, the current in the first primary winding is less than the current in the second partial winding.
    [0026] [0026] In an advantageous configuration, the number of intersections is an integer. It is therefore advantageous that a symmetrical arrangement can be produced in a simple manner.
    [0027] [0027] In an advantageous configuration, the winding wire of the respective turn of the first winding extends before an intersection inside and, after the crossing, outside the respectively associated turn of the second partial winding or the winding wire of the respective turn of the first winding winding extends before an outside crossing and, after crossing, inside the respectively associated turn of the second partial winding. It is therefore advantageous that a symmetrical winding arrangement can be produced in a simple way by crossing.
    [0028] [0028] In an advantageous configuration, the crossings in the direction of turn of a respective turn of the first and / or the second partial winding are regularly spaced apart. It is therefore advantageous that a symmetrical winding arrangement can again be produced in a simple way.
    [0029] [0029] In an advantageous configuration, the distance between a respective turn of the first partial winding and the associated associated turn of the second partial winding is constant. It is therefore advantageous that an area as large as possible can be envisaged for the winding arrangement and, in addition, a magnetic field as homogeneous as possible can be produced.
    [0030] [0030] In an advantageous configuration, the partial windings are parallel electrically connected to each other. It is therefore advantageous that a uniform current and, as a result, a magnetic field as homogeneous as possible can be achieved.
    [0031] [0031] In an advantageous configuration, the partial windings are respectively flat windings, the flat winding being arranged respectively within a winding area, especially if the winding area is curved extending. It is therefore advantageous that water can flow from the middle of the winding, when the area is convexly curved, therefore falling from the middle of the coil to the edge of the coil. Also, when the winding is covered by a housing part of constant wall thickness, for example a covering part, then this water drain advantage remains. The maximum of the winding area is then arranged above in the gravity field and the edge of the coil area below.
    [0032] [0032] In an advantageous configuration, the partial windings are flat windings, with the exception of the crossing regions and / or the exit regions of the extreme regions of winding wire. It is therefore advantageous that simple production is possible.
    [0033] [0033] In an advantageous configuration, as a winding wire a cord is employed, especially with the cord being executed as a bundle of individual wires electrically isolated from each other, the cord being especially round, the beam having an essentially round cross section. It is therefore advantageous that a simple, low-cost winding yarn can be used. By using an insulated enclosure, the winding and electronics can be guaranteed to be weatherproof.
    [0034] [0034] Important characteristics in the arrangement, especially the charging station, for the transmission of energy without contact to an electric vehicle, with a winding arrangement previously mentioned, is that an alternating current source is applied to the connected partial windings. in parallel, the vehicle on its underside has a secondary winding, which is inductively attachable to the winding arrangement. It is therefore advantageous that energy can be transmitted without contact and, due to the homogeneous course of the magnetic field, the inductive coupling intensity depends only slightly on the vehicle's displacements.
    [0035] [0035] Other advantages result from the achievements. The invention is not restricted to the combination of characteristics of the embodiments. In particular, there are other possibilities for significant combinations of embodiments and / or characteristics of individual embodiments and / or characteristics of the description and / or figures, especially the placement of the objective and / or the objective that is placed in comparison with the current state of the technical.
    [0036] [0036] The invention will then be explained in detail based on figures.
    [0037] [0037] In figure 1 is shown a flat spiral winding, especially of round cord, consisting of the winding wire in a bundle of individual wires electrically isolated from each other.
    [0038] [0038] Figure 2 shows a flat spiral winding that can be assembled from two partial windings, the partial windings being spaced apart.
    [0039] [0039] In figure 3 there is schematically represented an arrangement according to the invention, which is carried out as a flat spiral winding.
    [0040] [0040] In figure 4 is shown a stationary part of the charging station for electric vehicles in an inclined view.
    [0041] [0041] In figure 5 a corresponding cross section is shown.
    [0042] [0042] In figure 6 a corresponding longitudinal section is shown.
    [0043] [0043] In figure 7 is shown the stationary part in exploded representation.
    [0044] [0044] Figure 8 shows the housing of the primary conductor 41 in the winding support 42 by means of a rear cut 50.
    [0045] [0045] Figure 9 shows the winding arrangement 41 in view from the top.
    [0046] [0046] Figure 10 shows the winding arrangement 41 in an inclined view.
    [0047] [0047] In figure 11 is shown the layer of ferrite plate 44 with gaps, therefore notches 80.
    [0048] [0048] Figure 12 shows the schematic structure of the stationary part, making it clear that it is arranged in the bottom area 90 and has a curved surface, with an electronics part 49 being protected inside.
    [0049] [0049] Figure 13 shows the magnetic flux within the layer of ferrite plate 44 as an example for two variants, with the possibility of extending unimpeded lines in a longitudinal direction and in a straight line or in a transverse direction, in the longitudinal direction. field 100 flows around notches 80 filled with plastic support domes 48. Thus, it is clear that the magnetic flux in both directions can extend without particular obstacles. It is also shown then that the support domes 48 are regularly arranged within the layer of ferrite plate 44 and, thus, form a flat grid, which is formed of rows arranged parallel to each other, uniformly spaced from each other, which are executed in a similar manner. likewise and along which respectively the support domes 48 are regularly spaced apart from each other with a first grid constant, with rows directly neighboring a gap in a row direction, especially in a first half grid constant value. The ferrite plates 44 are all made equal and arranged in rows showing a lag with the row directly neighboring respectively. All the rows mentioned are executed straight.
    [0050] [0050] In figure 14 is shown a schematic section, which represents the lines of force produced by a vehicle parked on a stationary part, making it clear that the ferrite plates 44 are not loaded, because the outside lines are bypassed by the domes of support 48.
    [0051] [0051] In figure 1 is shown a flat spiral winding, especially of round cord, consisting of winding wire 1 in a bundle of individual wires electrically isolated from each other, therefore of HF cord.
    [0052] [0052] In figure 2 is shown a flat spiral winding, mountable from two partial windings, the partial windings being spaced apart. The winding wire 20 of the first partial winding is represented with a continuous line and the winding wire 21 of the second partial winding is represented with a dashed line.
    [0053] [0053] In figure 3 is shown a flat spiral winding according to the invention.
    [0054] [0054] As shown in figure 1, a flat winding, therefore winding practically two-dimensional, can be performed rectangular-spiral, being performed between the turns that are respectively neighbors of the winding a distance that is greater than the diameter of the winding wire. Thus, each turn is distanced from the previous turn outwards, especially, therefore, radially. The distance matters in a multiple of the diameter of the winding wire, the distance value rising monotonously from the outer coil edge to the middle of the coil, especially quite monotonously. The multiple means, for example, the triple or more. The distance between the mutually following turns of the respective partial winding therefore increases from the outside to the inside, because the area enclosed between two mutually following turns of the respective partial winding has the same value respectively.
    [0055] [0055] As a winding wire, a round cord is used. The spatial extension of this cord is therefore not negligible and in the region of the winding wire of each spiral the magnetic field produced by the winding is less homogeneous than in the region between the turns.
    [0056] [0056] As shown in figure 2, by executing the winding by means of two partial windings (20, 21) a more homogeneous magnetic field course can be obtained through the coiled area and a distance in half, however, being used twice as much winding wire. For in the region of the winding wire of the loop of a first partial winding the other partial winding produces a more homogeneous magnetic field course than the first partial winding. However, the other partial winding always extends within the first partial winding, so the inductivity of the partial windings is different.
    [0057] [0057] As shown in figure 3, in the partial windings provided in correspondence to figure 2, according to the invention, additionally, crossings of the winding wires of both partial windings are provided. The winding wires are electrically isolated from each other and a very homogeneous magnetic field results from the winding area. In addition, the two partial windings have the same inductivity.
    [0058] [0058] Two crossings are associated with each complete turn. Thus, the winding thread of one loop of a partial winding extends through a half turn inside and through the other half turn outside the corresponding turn of the other partial winding.
    [0059] [0059] With the exception of crossing regions and exit regions and / or corner regions, there is a constant distance. The shape of the loop, therefore the length of the loop, of the mutually corresponding turns of the partial windings, is symmetrical to each other, especially symmetrical to a plane that is perpendicular to the winding plane and cuts through the crossing regions.
    [0060] [0060] In the region of the especially radial exit of the winding wire of each partial winding, the winding wire of each turn of the corresponding first partial winding is guided in a staggered way, therefore almost abruptly, at a respectively greater radial distance. The increase in radial distance is in this region respectively very large, especially greater than along the winding wire before or after the region.
    [0061] [0061] In fact, the partial windings can be arranged in the same plane, but in the crossing region an extension of the winding space perpendicular to that plane is necessary. This applies correspondingly to the region of the access and exit duct. Alternatively, the two partial windings are arranged in two planes parallel to each other, but spaced apart from each other.
    [0062] [0062] The two partial windings are connected electrically in parallel, so that the applied alternating current is evenly distributed in both partial windings. Even when supplying an alternating current of medium frequency, a uniform distribution can be achieved due to the equality of the inductivities.
    [0063] [0063] The frequency of the alternating current applied is preferably between 10 kHz and 1 MHz.
    [0064] [0064] The winding can be arranged on the bottom, so that a vehicle with a secondary winding attached to it can be moved by the flat winding and by the inductive coupling of the secondary winding with the primary winding arrangement, especially therefore with the flat winding as primary winding, energy can be transmitted without contact, especially also galvanically separated.
    [0065] [0065] In another embodiment according to the invention, instead of the respective plane for the winding, an area that extends spatially curved can be used.
    [0066] [0066] In another example of execution according to the invention, instead of the two crossings per turn 2 * n intersections, especially uniformly spaced apart in the direction of the turn, and / or instead of two partial windings, more are used partial windings connected in parallel. n is then an integer. The rolled areas of the respective partial windings are then equally equal.
    [0067] [0067] As shown in figures 4 to 7, the stationary part of the charging station, therefore the primary winding arrangement, is covered by a cover part 1, which is preferably made of aluminum or plastic and screwed using screws 2 in a threaded hole in the base or in a bolt fixed to the base.
    [0068] [0068] The cover part 1 preferably made of aluminum or plastic thus protects the winding arrangement of primary conductor 41, which is under it, and a frame antenna 40 for data transmission.
    [0069] [0069] The primary conductor winding arrangement 41 is provided in a winding support 42, which has a rear cutout 50 for housing the primary conductor, so that the primary conductor 41 is enclipable, especially in corresponding slots or grooves.
    [0070] [0070] The winding support 42 is seated on a layer of rectangular ferrite plates 44, which are arranged on a support 45, especially glued.
    [0071] [0071] Support 45 is preferably made of aluminum as a magnetic shield.
    [0072] [0072] The support 45 and the layer of ferrite plates 44 have rectangular gaps, therefore notches 46, which are arranged coincidentally. The shape of the respective gap corresponds to a ferrite plate.
    [0073] [0073] The bottom part 47 has rectangular support domes 48, which protrude through the notches 46 in the support 45 and gaps 80 in the layer of ferrite plates 44. Preferably, between the support domes 45 and the layer of plates ferrite 44 there is an air gap to compensate for thermally conditioned length variations.
    [0074] [0074] In this way, when introducing a portion of gravity force of a vehicle at least partially placed on the cover part 1, specially parked, that portion of the cover part 1 is forwarded to the winding support 42, without the winding wire of the winding arrangement is deformed. This winding wire is in fact HF cord, especially round cord, therefore executed from a bundle of individual wires electrically isolated from each other; but the winding wire is housed by means of a rear cut 50 by positive joining in a notch of the winding support 42 housing the wire. This notch has a larger cross-sectional area than that of the winding wire, so that, even with deformation of the winding support 46 under the influence of the force portion, the winding wire is not exposed to a force effect and there is no deformation of the winding wire, especially the cross section of the winding wire.
    [0075] [0075] The force portion is then directed by the winding support 42 through the support domes 48 of the bottom part 47 to the bottom area 90.
    [0076] [0076] As the support domes 48 protrude through the notches 46 and the gaps 80, the force portion can also be driven through the layer of ferrite plates 44. Thus, the brittle material of the ferrite plates 44 is not requested.
    [0077] [0077] The respective extreme regions of the winding wire are added to the electronics part 49 and electrically connected there with the connection of the electronics part 49, by means of connection devices, especially connection clamps. Also, the frame antenna is connected with the electronics part and in this way enables signal transmission to the secondary winding of the vehicle.
    [0078] [0078] The bottom part 47 is made convexly convex, so that the water flows. For simple manufacturing, then a pyramid trunk can be used. Through the bulging, a spatial region can also be protected, which makes it possible to accommodate the electronics part 49.
    [0079] [0079] The winding arrangement has two partial windings, whose winding wires cross at several points. A partial amount of the crossing points is arranged in a line, which extends from the inside to the outside, therefore, from the internal region housing the electronics part 49 outwards, therefore towards the outer periphery of the bottom part 47. The support 42, especially, therefore, winding support, has recesses correspondingly extending, in which the intersections are housed. These recesses therefore also allow water to drain. As the recesses are executed with a width such that water can also flow around the intersections in the respective recess.
    [0080] [0080] The layer of ferrite plates consists of ferrite plates 44 arranged in a row behind each other, with the ferrite plates 44 of each two rows directly adjacent a lag between them. For the end of the row, ferrite plates of half the length are used in the extreme regions of each second row in comparison with the ferrite plates 44 in addition of the same nature. The lag essentially corresponds to half a plate length.
    [0081] [0081] The gaps 80 for the passage of the support domes 48 are spaced in such a way that at least two ferrite plates 44 can be arranged in between. The shape of the respective gaps 80 corresponds to one of the ferrite plates 44 of the same nature .
    [0082] [0082] In another embodiment according to the invention, instead of two intersections per loop, 2 * n intersections are performed, especially evenly spaced apart in the direction of the loop, and / or instead of two partial windings plus windings parallel connections. n is then an integer. The rolled areas of the respective partial windings are then equally equal.
