Disclosure of Invention
The object of the invention is to provide a coil arrangement for a motor vehicle, a method for mounting a coil arrangement, and a motor vehicle, by means of which a secondary coil can be mounted particularly easily on the underside of the motor vehicle and accessibility to vehicle components arranged above the coil arrangement after body-chassis mounting (Fahrwerkshochzeit) can be achieved particularly advantageously.
According to the invention, this object is achieved by a coil arrangement for a motor vehicle, a method for mounting a coil on the underside of a motor vehicle, and a motor vehicle having the features of the independent claims. Advantageous embodiments with suitable developments of the invention are specified in the respective dependent claims and the following description.
In order to provide a coil arrangement for a motor vehicle of the type mentioned at the outset, by means of which the secondary coil can be mounted particularly easily on the underside of the motor vehicle and which makes it possible to particularly advantageously provide accessibility to vehicle components which are arranged above the coil arrangement after the body-chassis assembly, it is proposed according to the invention that the secondary coil is held on the energy accumulator arrangement or the auxiliary frame so as to be displaceable between a mounting position and a loading position by means of the bearing arrangement. The secondary coil is thus held on the energy accumulator device or on the auxiliary frame by means of the bearing device and is arranged in the assembly position during the assembly process and in the installed position in the installed state. The secondary coil can be displaced between the mounting position and the installation position by means of a bearing, which can be a hinge, for example. In particular, the secondary coil is held in the assembled position on the energy accumulator device or the auxiliary frame in such a way that the whole of the energy accumulator device or the auxiliary frame and the secondary coil is particularly space-saving and can therefore be assembled particularly easily on the underside of the motor vehicle. In addition, components arranged on the vehicle above the coil arrangement in the installed position of the coil arrangement can be accessed particularly advantageously by means of the coil arrangement according to the invention. In particular, the plug connections and lines of the components are particularly easily accessible in the assembled position of the secondary coil, so that the plug connections and lines can be accessed particularly easily by after-market service personnel without the secondary coil having to be completely disassembled.
Preferably, the secondary coil can be pivoted about the pivot axis between the installation position and the installation position by means of the bearing. The pivot axis extends, for example, along a narrow side of the secondary coil and, in the installed position, along a vehicle transverse direction or a vehicle longitudinal direction of the motor vehicle. The narrow side of the secondary coil may be a narrow side of a housing of the secondary coil of the automobile. In this case, the secondary coil can be pivoted about the pivot axis when it is displaced from the mounting position into the installation position and can be folded in the mounting position on the auxiliary frame or on the energy accumulator device, so that the secondary coil rests with its largest surface on the auxiliary frame or on the energy accumulator device. The largest surface of the secondary coil can be the largest surface of the housing of the secondary coil or the second largest surface opposite the largest surface. If the secondary coil and the auxiliary frame or the energy accumulator device are arranged in the assembly position overlapping the surface, the secondary coil can be assembled on the underside of the vehicle in a particularly simple and space-saving manner and can be pivoted about the pivot axis into the assembly position after it has been mounted on the underside of the vehicle.
In an advantageous embodiment of the invention, it is provided that the secondary coil is arranged between the energy accumulator device and the auxiliary frame in the installed position. That is, the secondary coil has a first side facing the subframe and a second side opposite to the first side, the second side facing the accumulator arrangement. For example, the first side is connected to the auxiliary frame and the second side is connected to the accumulator device. The support means may be arranged on a first side of the secondary coil or on a second side of the secondary coil and may be used for connecting the secondary coil with the auxiliary frame or the energy accumulator means, respectively. The arrangement of the secondary coil between the auxiliary frame and the energy accumulator device has the advantage that only a particularly short cable length of the cable for transmitting energy from the secondary coil to the energy accumulator device is required for connecting the energy accumulator device and the secondary coil.
Furthermore, it has proven to be advantageous if the secondary coil is connected in the installed position to the energy accumulator device or to the auxiliary frame by means of a threaded connection. For this purpose, the auxiliary frame or the energy accumulator device has a receptacle, by which the secondary coil can be received at least in regions. The receptacle may have a bore which can be connected with a corresponding bore of the secondary coil or of the secondary coil housing by means of a corresponding threaded connection. The hole of the secondary coil housing or of the receptacle can be in particular an elongated hole in order to achieve a clearance of the corresponding threaded connection. The side of the secondary coil having the at least one threaded connection is in particular opposite the side of the secondary coil on which the bearing is arranged. The secondary coil or the housing of the secondary coil is therefore connected on one side to the auxiliary frame and to the energy accumulator device by means of the bearing device and on the other side by means of at least one threaded connection. A particularly stable arrangement of the secondary coil between the energy accumulator device and the auxiliary frame can thereby be achieved.
In an advantageous embodiment of the invention, it is provided that the shape of the secondary coil is adapted to the shape of the support device, the shape of the auxiliary frame or the shape of the energy accumulator device. That is to say, the secondary coil is designed in particular such that, when the secondary coil is pivoted about the pivot axis, it does not impinge on the support device, nor on the auxiliary frame or on the energy accumulator device. For example, the shape of the secondary coil is adapted to the shape of the support means, the shape of the auxiliary frame and the shape of the energy accumulator means. The maximum possible pivot angle of the secondary coil about the pivot axis can thereby be advantageously achieved.
The invention also relates to a method for mounting a coil arrangement on the underside of a motor vehicle, wherein a secondary coil, which can charge an energy accumulator arrangement, is held on an auxiliary frame at least in its installed position. In order to mount the secondary coil on the underside of the motor vehicle in a particularly simple and space-saving manner, the secondary coil is held on the energy accumulator device or the auxiliary frame by means of a bearing device and is displaced between a mounting position and a mounting position. That is to say, the secondary coil is connected on at least one side to a support device, and the support device is in turn connected to an auxiliary frame or an energy accumulator device. The support device can be, for example, a hinge which forms a pivot axis for pivoting the secondary coil from the mounting position into the installation position. In the assembled position, the secondary coil is connected to the auxiliary frame or to the energy accumulator device, and in the installed position of the secondary coil, the secondary coil is connected to the auxiliary frame and to the energy accumulator device. For example, the secondary coil is connected in its assembled position only to the auxiliary frame or to the energy accumulator device via the bearing device. In the installed position, however, the secondary coil is connected both to the auxiliary frame and to the energy accumulator device.
In an advantageous embodiment of the invention, it is provided that the secondary coil is pivoted between the installation position and the installation position when the coil arrangement is installed on the underside of the motor vehicle. In other words, the secondary coil is first arranged in its assembly position, then fastened to the underside of the vehicle, and then pivoted out of the assembly position into the installation position. The secondary coil can therefore be fastened in a space-saving installation position on the underside of the vehicle and, after fastening thereof, can be pivoted into a mounting position which takes up more space than the installation position in order to be used later in this mounting position.
In a further advantageous embodiment of the invention, it is provided that the secondary coil is connected in its installed position to the energy accumulator device or to the auxiliary frame by means of a screw connection. In other words, the secondary coil is pivoted out of the assembly position into the installation position after it has been fastened to the underside of the motor vehicle and is connected to the energy accumulator device or to the auxiliary frame, in particular to a receptacle of the energy accumulator device or the auxiliary frame, by means of at least one threaded connection. For this purpose, the secondary coil or the housing of the secondary coil and the receptacle of the energy accumulator device or the auxiliary frame each have holes, in particular oblong holes, which correspond to one another and are connected to one another by means of corresponding threaded connections. This achieves a particularly secure assembly of the secondary coil on the underside of the motor vehicle and a secure fastening of the secondary coil to the auxiliary frame and the energy accumulator device by means of the threaded connection and by means of the bearing device.
The invention further relates to a motor vehicle having a coil arrangement as already described in connection with the coil arrangement according to the invention, which coil arrangement is mounted on the underside of the motor vehicle according to the method as already described in connection with the method according to the invention.
The invention also includes the advantages and improvements of the motor vehicle according to the invention, which has the features already described in connection with the improvements and advantages of the coil arrangement according to the invention and of the method according to the invention. The corresponding advantages and improvements of the motor vehicle according to the invention are therefore not described here.

Detailed Description
The examples described below are preferred embodiments of the invention. The individual parts of the embodiments described represent individual features of the invention which can be considered as independent of one another, which also improve the invention independently of one another, and can therefore also be considered as constituent parts of the invention, individually or in different combinations than those shown. The described embodiments can also be supplemented by other features of the invention already described.
In the figures, functionally identical elements are provided with the same reference symbols.
Fig. 1 shows a schematic perspective view of a coil arrangement 1, wherein this view corresponds to an oblique plan view of the underside of a motor vehicle. The coil arrangement 1 shown in fig. 1 for a motor vehicle, which is not shown, comprises a secondary coil 2 and an energy accumulator arrangement 3, which can be charged via the secondary coil 2. The coil arrangement 1 also has an auxiliary frame 4 on which the secondary coil 2 is held at least in the installation position 5 shown in fig. 1.
In order to be able to mount the secondary coil 2 on the underside of the motor vehicle in a particularly simple and space-saving manner, the secondary coil 2 is held on the energy accumulator device 3 or the auxiliary frame 4 so as to be displaceable between the mounting position 7 and the installation position 5 by means of the bearing device 6.
In the installed position 5 of the secondary coil, the secondary coil 2 is arranged at least substantially parallel to the extension surface of the energy accumulator device 3 and the extension surface of the auxiliary frame 4.
Fig. 2 shows the coil arrangement 1 in a schematic perspective view, turned 180 degrees compared to fig. 1. This perspective view corresponds to a diagonal top view of the coil arrangement 1 when the coil arrangement is in the installed position in a not shown motor vehicle. As can be seen with simultaneous reference to fig. 1 and 2, the secondary coil 2, the auxiliary frame 4 and the energy accumulator arrangement 3 are arranged at least substantially in the same plane. It can also be seen that the secondary coil 2 is arranged between the energy accumulator device 3 and the auxiliary frame 4 in the installation position 5.
Fig. 3 shows a schematic perspective view of the coil arrangement 1 as a plan view from below in the direction of the underside of the motor vehicle. In this view, it can be seen that the secondary coil 2 is held on the auxiliary frame 4 by means of a bearing 6. For this purpose, the support device 6 comprises two support elements 8, by means of which the secondary coil 2 is displaceably held on the auxiliary frame 4. The secondary coil 2 is supported on the auxiliary frame 4 so as to be pivotable about a pivot axis 9. The swing axis 9 may be formed by a first narrow side 10 of the secondary coil 2. Alternatively or additionally, the pivot axis 9 can be formed by a carrier element 11 of the auxiliary frame 4. On a second narrow side 12 opposite the first narrow side 10, the secondary coil 2 is held in its installation position 5 on the energy accumulator device 3 by means of a threaded connection 13. The threaded connection 13 comprises four screws 14, by means of which four elongated holes 15 of the secondary coil 2 can be brought into engagement with four corresponding holes 16 of a receptacle 17 of the energy accumulator device 3. In its installation position 5, the secondary coil 2 is fastened to the energy accumulator device 3 or to a receptacle 17 of the energy accumulator device 3 by means of a threaded connection 13.
As can also be seen from fig. 3, the shape of the secondary coil 2 matches the shape of the sub-frame 4. The secondary coil 2 has two lateral surfaces 18, the shape of which is adapted to the two holding elements 19 of the auxiliary frame 4, so that the lateral surfaces 18 are prevented from striking the holding elements 19 during a pivoting movement of the secondary coil 2 about the pivot axis 9.
Fig. 4 shows the secondary coil 2 in a schematic perspective view. In this illustration, it can be seen that the bearing element 8 of the bearing arrangement 6 is designed as a hinge, by means of which the secondary coil 2 can be pivoted about a pivot axis 9. As can also be seen from fig. 4, the receptacle 17 is designed such that the secondary coil 2 rests locally against the receptacle 17. In this case, the region of the secondary coil 2 in which the elongated hole 15 of the secondary coil 2 is arranged rests on the receptacle 17. The elongated hole 15 is arranged perpendicular to the plane formed by the energy accumulator device 3, the secondary coil 2 and the auxiliary frame 4 and in the present case extends along a straight line lying in this plane and formed perpendicular to the pivot axis 9. This results in a relative movement of the secondary coil 2 and the auxiliary frame 4 relative to the energy accumulator device 3 perpendicular to the pivot axis 9 in the installation position 5 of the secondary coil 2.
When the region of the secondary coil 2 is arranged on the receptacle 17 in the installed position, the elongated hole 15 corresponding to the hole 16, the hole 16 being arranged on the side of the connection of the secondary coil 2 to the receptacle 17 facing the interior of the vehicle, and the elongated hole 15 facing the traffic lane in which the vehicle is located.
In fig. 5 and 6, a schematic perspective view of the secondary coil 2 on the underside of the motor vehicle is shown obliquely from below when the coil arrangement 1 is mounted on the underside of the motor vehicle. Fig. 5 shows the secondary coil 2 in its installation position 5, while fig. 6 shows the secondary coil 2 in its installation position 7. As can be seen from fig. 5 and 6, the secondary coil 2 can be pivoted about a pivot axis 9 between the mounting position 7 and the installation position 5 by means of the bearing arrangement 6. When the secondary coil 2 is mounted on the underside of the motor vehicle, the secondary coil 2 is fastened together with the auxiliary frame 4 in its mounting position 7 shown in fig. 6 on the underside of the motor vehicle. As shown in fig. 6, the secondary coil 2 can be pivoted by at least 90 degrees relative to the installation position 5 shown in fig. 5, but the secondary coil 2 can also be pivoted by a greater angle, for example 180 degrees, relative to the installation position 5.
After the secondary coil 2 has been fastened in its installation position 7 on the underside of the motor vehicle by means of the subframe 4, the secondary coil 2 is pivoted into the installation position 5 shown in fig. 5. In this case, the secondary coil 2 partially rests against a receptacle 17 of the energy accumulator device 3, and the elongated hole 15 of the secondary coil 2 corresponds to the hole 16 of the receptacle 17. By means of a bolt 14, which is not shown in detail, the secondary winding 2 can be fixed in the installation position 5 on the receptacle 17 by means of an elongated hole 15 corresponding to the hole 16 and the bolt 14. The secondary coil 2 is thereby connected to the energy accumulator device 3 via the receptacle 17 by means of the threaded connection 13. Instead of using a threaded connection 13, the secondary coil 2 can alternatively be fastened to the receptacle 17 of the energy accumulator device 3 by means of other releasable fastening means. The energy storage device 3 is a power cell in this case. The ability of the secondary coil 2 to pivot about the pivot axis 9 by means of the articulated bearing element 8 prevents complex overhead assembly of the secondary coil 2 on the underside of the motor vehicle and also allows particularly good accessibility to the secondary coil 2 in the motor vehicle. In addition, since the secondary coil is arranged between the auxiliary frame 4 and the energy accumulator arrangement 3, the secondary coil 2 can be connected to the energy accumulator arrangement 3 for energy transmission via a cable having a particularly short cable length. The coil arrangement 1 is thus particularly lightweight and cost-effective.
In general, these examples show how a deformation element, for example an auxiliary frame, can be connected to a secondary coil by means of the invention.
