Description

Technical Field

[0001] One aspect of the invention relates to a vehicle device comprising a housing in which at least one printed circuit board is arranged. Background Art

[0002] Vehicle devices are known in various designs. They can be a variety of component groups, in which a wired electrical connection is to be established. In particular, when the vehicle device also includes a housing, in which an interconnection device or a printed circuit board, respectively, is arranged, and for this purpose a wired connection to an external component part of the vehicle device is to be achieved, various aspects arise. Summary of the invention

[0003] The object of the present invention is to provide a vehicle device in which the electrical connection between a printed circuit board and another component of the vehicle device is technically improved in a wired manner.

[0004] This object is achieved by a vehicle arrangement comprising the features according to claim 1 .

[0005] One aspect of the invention relates to a vehicle device comprising a housing. In addition, the vehicle device comprises at least one printed circuit board arranged in the housing. In addition, the vehicle device comprises a fan. The fan is arranged outside the housing. In addition, the vehicle device comprises at least one cable, which is laid through a cable opening in the housing and extends outside and inside the housing. The cable is connected to an electrical connection of the fan. In addition, the cable is also connected to the printed circuit board in the housing. The cable outside the housing is arranged on a cable guide element of the vehicle device. The guide element is arranged adjacent to the cable opening. The cable is arranged to bend towards the cable opening through the guide element. The cable opening is arranged at a height position observed in the height direction of the vehicle device, which height position is higher than the lowest point of the guide element. At this lowest point of the guide element, the cable contacts the guide element, in particular directly. Therefore, this means that the lowest point of the guide element is considered to be the point at which the cable opening also contacts, in particular directly contacts, the guide element.

[0006] By means of such a vehicle device, it is facilitated to form an electrical wired connection between a printed circuit board in the housing and a fan of the vehicle device outside the housing. Since in such an arrangement the cable opening in the housing is required to be configured so that the cable can be laid from the interior of the housing outwards towards the fan, effects which are to be observed there may occur. This can be, for example, a correspondingly stable laying of the cable in the area of ​​the cable opening. In particular, a precisely positioned laying of the cable should also be facilitated here. Unwanted movements or tolerances of the cable should thus be avoided. Furthermore, in order to avoid undesired displacements, the cables should preferably also be arranged as tightly as possible in the corresponding openings. In particular, it is also conceivable that the ingress of liquids into the housing, in particular through the cable opening, can be avoided in an improved manner.

[0007] This is achieved in many aspects of the proposed vehicle device. This is because the cable is already guided to the cable opening in a highly directional and guided manner by means of the guide element arranged adjacent to the cable opening. As a result, the cable may already contact the guide element fixed in place, in particular also in a tight manner. In particular, by means of the guide element, the cable is thus also diverted to the cable opening in a highly targeted and highly defined manner. In addition, the guiding of the cable by means of the guide element outside the cable opening so that it is positioned at a point lower than the area of ​​the cable opening itself can also be better avoided by means of this very clearly established and desired height offset for the medium to enter the cable opening via the cable. This is because in this way, in particular, for example, by means of this precise position definition, liquids can also flow along the cable to the outside of the housing. However, due to this height offset, it is impossible for water rising from the lowest point to reach the cable opening again and then reach the interior of the housing through the cable opening. In addition, by means of this height offset, it is also very advantageously facilitated that the cable from this lowest point to the cable opening is equally arranged in an accurate position and tensioned. As a result, undesirable movement tolerances of the cable can also be avoided in this area.

[0008] In an embodiment, the cable is laid upwards towards the cable opening starting from the lowest point, at which the cable is arranged to contact the guide element. The advantages of this aspect have already been mentioned above. In an embodiment, the cable opening is delimited by a ridge that rises at least on one side. Therefore, this rising ridge is also guided from the bottom to the top. Therefore, in an embodiment, the cable is guided from the guide element carried by the rising ridge and targeted to the cable opening. As a result, a higher positioning of the cable directly at the cable opening or its entry is also achieved.

[0009] It is conceivable that the bulge is a hump-shaped bulge. In particular, on the outer surface of the housing, the bulge rises here, then reaches a maximum and slopes downward again towards the interior of the housing. A hump shape is thus formed. The highest positioning point defined at the cable opening is configured by this configuration of the maximum bulge. In an advantageous embodiment, exactly at the cable opening, there is the maximum of the hump-shaped tip or the hump-shaped bulge, respectively. Therefore, exactly in the area of ​​the cable opening, the cable at this vertex can be particularly advantageously guided or laid, respectively. Therefore, at this precise height position in the cable opening, a very locally defined bearing area of ​​the cable is achieved. Therefore, the internal width of the cable opening observed in the height direction can also be minimized, so that a gap-like opening can be configured. In addition, thereby, on the one hand, it is advantageously facilitated that the cable is relatively accurately assembled through the cable opening, and this higher position state of the cable at the cable opening is still supported compared to the lowest point on the guide element. It is also important that the tight laying of the cable in the interior of the housing is advantageously supported by this arrangement of the maximum of the hump-shaped bulge exactly in the area of ​​the cable opening or at the entrance of the cable opening.

[0010] In an embodiment, the protrusion comprises a protrusion plateau. The protrusion plateau is arranged at a height position higher than the lowest point of the guide element, and the guide element is arranged at the lowest point to directly contact the guide element. The protrusion plateau may be the above-mentioned maximum of the hump-shaped protrusion.

[0011] In the embodiment, a bottleneck of the cable opening viewed in the height direction is formed by the raised plateau. Again, for this purpose, the advantages that can be achieved have already been listed above. This smallest possible inner width of the cable opening, in particular in the height direction, also facilitates the concept of saving space here. In addition, it is facilitated to pass the cable through the cable opening compactly, so that the smallest possible gap is formed between the cable and the cable opening.

[0012] In an embodiment, the bottleneck viewed in the height direction of the vehicle arrangement is arranged to be positioned above the lowest point of the guide element contacted by the cable.

[0013] In an embodiment, the protuberance comprises an outer wall that is inclined downward outward. This downward inclination outward is to be understood in particular as the outer wall starting from the entrance of the cable opening being inclined downward toward the guide element. In particular, a downward inclination can be configured here. Therefore, very advantageously, by means of the outer wall oriented in this way, a further guiding of the cable independent of the guide element and toward the cable opening is also achieved. In addition, by means of this outer wall that is inclined downward outward, the advantages of avoiding the entry of the medium into the cable opening are also supported. In particular, the outer wall that is inclined downward outward and observed in the height direction is at least partially arranged to overlap with the guide element. Therefore, to a certain extent, a labyrinthine path between the guide element and the outer wall that is inclined downward outward is formed in front of the cable. This also forms a favorable laying path for the cable, in particular with regard to the advantages already mentioned above.

[0014] In an embodiment, the outer wall which is inclined downwards towards the outside is curved, in particular at least partially concavely curved. This is another advantageous embodiment in order to achieve a safe laying of the cable from the guide element towards the cable opening. Thus, the cable can be guided to the cable opening very advantageously. It is also important that, by means of this concave curvature, the avoidance of media such as dust or liquids from entering the cable opening is also supported in an enhanced manner.

[0015] In an embodiment, the outer wall is arranged adjacent to the guide element so that a conduit for the cable is formed between the lower outer side of the guide element and the outer wall. This also improves the laying of the cable and the targeted guidance of the cable towards the cable opening.

[0016] In an embodiment, the shape of the lower outer side of the guide element is adapted to the shape of the outer wall. It is thus possible to achieve a defined guiding method, in particular also to lay the cable in a tensioned state, in an improved manner.

[0017] In an embodiment, a downwardly inclined rod is formed on the outer edge of the outer wall. In particular, the outer edge is the edge facing away from the cable opening. The outer edge in height is in particular the lowest point of the outer wall. The inclined rod formed integrally therewith promotes in a particularly advantageous manner the avoidance of medium from entering the cable opening. In addition, the outer wall is stabilized by this inclined rod. In particular, the rod is then also a reinforcing rod.

[0018] In an embodiment, the rod is configured as a drip edge for liquids and / or as a splash protection element for liquids towards the cable opening. This also means that, via the rod, liquids that may drip from the cable, such as condensate, for example, can be drained downwards via the rod and can drip, and it is prevented in an improved manner that the liquid can reach the cable opening. Furthermore, when water splashing from the outside could splash onto the vehicle device in the region of the guide element, a protective shield can be formed by the rod, so that in this respect also splashing water cannot reach the cable opening via the outer wall, as already mentioned above.

[0019] In an embodiment, the guide element comprises a cylinder segment, at which the cable is laid in a curved manner and is arranged directly thereon. The guide element designed as a cylinder segment can be configured, for example, as a semi-cylindrical cylinder segment. Thus, a contour without corners can be produced, on which the cable is guided in direct contact and bent accordingly. This facilitates a very continuous change of the cable direction without undesired bends in the cable. In this form, the cable can also be turned in a targeted manner towards the cable opening.

[0020] In an embodiment, the guide elements each comprise a guide wall, which is arranged to extend from the cylinder segment, so that the cylinder segment viewed in the axial direction is delimited by the guide wall. In particular, a guide element in the form of a cable drum is then formed by these guide walls and the cylinder segment positioned therebetween. Thus, on the one hand, the cable contacts the outer wall of the cylinder segment. On the other hand, by the guide wall formed on the end face, it is also achieved that the cable is prevented from shifting on the cylinder segment.

[0021] In the radial direction of the cylinder segment, the guide walls are formed to protrude beyond the cylinder segment.

[0022] In an embodiment, a fan housing of the fan is arranged on an outer surface of a housing of the vehicle device, in which the printed circuit board is arranged. In this respect, the fan housing can be arranged directly on the housing on the outer surface. It can, for example, be screwed together with it. A plug-in connection or a snap-on connection is also possible. It is also possible that the fan housing is formed integrally with the housing in which the printed circuit board is arranged. In such an embodiment, the printed circuit board is also separated from the fan impeller of the fan, in particular by a housing wall that is separated in this respect.

[0023] In an embodiment, the fan housing preferably also comprises a cable opening, through which the cable is then also guided into the interior of the fan housing in order to be able to be connected there to the electrical connection.

[0024] In an embodiment, the guide element comprises at least one anti-lost element. The anti-lost element is used in particular to hold the cable on the guide element. In particular, an anti-lost pin is formed by the anti-lost element. It can also be preferably arranged on the inner surface of the guide wall facing the other guide wall opposite. Therefore, the anti-lost pin extends from the inner surface of one guide wall to the other guide wall, in particular cantilevered. Therefore, in particular, radial slipping of the cable from the guide element is avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiments of the present invention are explained in more detail below with reference to the accompanying drawings. These show:

[0026] Figure 1 is a perspective sectional view through an embodiment of a vehicle arrangement according to the invention, in which the vehicle arrangement is partially shown; and

[0027] Figure 2 It is shown in perspective from below. Figure 1 Representation of the sub-parts in .

[0028] In the figures, identical elements and elements having the same function are provided with the same reference symbols. DETAILED DESCRIPTION

[0029] exist Figure 1 In FIG. 1 , a vehicle device 1 is shown. The vehicle device 1 may also be referred to as a vehicle equipment or a vehicle unit. The vehicle device 1 is installed in a vehicle, such as a motor vehicle. Therefore, the vehicle device 1 is intentionally designed for use in a vehicle, in particular a motor vehicle.

[0030] The vehicle device 1 comprises a housing 2. In an embodiment, the housing 2 is a circumferentially closed, in particular a completely closed housing. It can be made of metal. In addition, the vehicle device 1 comprises a fan 3. The fan 3 comprises a fan housing 4. In the fan housing 4, at least one fan impeller 5 is arranged, which is mounted so as to be rotatable about an axis A. In this embodiment, the fan housing 4 is arranged outside the housing 2. It can be a fan housing 4 separated from the housing 2.

[0031] The fan housing 4 can be connected to the housing 2, for example, by a threaded connection and / or an insert connection and / or a snap connection. It is also possible that the housing 2 and the fan housing 4 are formed in one piece. In such a common housing, a first chamber is formed, in which the fan impeller 5 is arranged. In a second chamber, which is different and separate therefrom, further components are arranged.

[0032] In the housing 2, a component arrangement 6 is arranged. In the housing 2, in particular, at least one printed circuit board 7 is also arranged. The printed circuit board 7 is thus separated from the fan 3. In particular, the printed circuit board 7 is separated from the fan impeller 5 by a wall 8. The wall 8 can be a housing wall of the housing 2. It can also be a housing wall of the fan housing 4. In different embodiments, in which the housing 2 and the fan housing 4 are configured as one-piece, it can be an internal partition wall.

[0033] The fan 4 comprises an electrical connection 9. The electrical connection 9 is arranged in particular inside the fan housing 4. The fan housing 4 comprises a cable opening 10. A cable 11 of the vehicle device 1 is guided through the cable opening 10. Thus, the cable 11 is laid inside the fan housing 4 and outside the fan housing 4. The cable 11 establishes a wired connection between the fan 3 and the printed circuit board 7. Thus, the cable 11 is also introduced into the interior of the housing 2. In this embodiment, the vehicle device 1 comprises a guide element 12. It can be referred to as a cable guide element. The guide element 12 is a component of the housing 2. The guide element 12 can be formed integrally with the housing 2. The guide element 12 is arranged adjacent to a cable opening 13 in the housing 2. The cable opening 13 represents a passage from the outside of the housing 2 to the inside of the housing 2, through which the cable 11 is guided or laid, respectively. In the height direction (y direction) of the vehicle device 1, the cable opening 13 is arranged to be positioned higher than the lowest point 14 of the guide element 12, which is also contacted by the cable 11. At this lowest point 14 in the embodiment, the cable 11 is arranged to be in direct contact. Therefore, the portion of the cable 11 located below that arranged in the cable opening 13 is also arranged outside the housing 2. This height offset between the lowest point 14 and the cable opening 13 is in an embodiment at least equal to the thickness d of the cable.

[0034] It can be seen that the cable 11 is laid from this lowest point 14 upwards towards the cable opening 13. In particular, in this respect, it is laid with an S-shaped cross section. This means that the S-shape is predetermined by the contours of the guide element 12 and the additional components.

[0035] The cable opening 13 is defined by at least one bulge 15 which rises towards the cable opening 13 at least on one side. In particular, the bulge 15 is configured in a hump shape. This means that the bulge 15 comprises an outer wall 16 which slopes downwards from the cable opening 13 towards the outside. The outer wall 16 therein is an outer wall which leads outwards and downwards from the cable opening 13. In particular, the outer wall 16 which slopes downwards towards the outside is at least partially concavely curved. In an embodiment, by the hump shape of the bulge 15, an inner wall 17 is also formed. The inner wall 17 slopes downwards from a bulge plateau 18 which, viewed in the height direction, represents the maximum of the bulge. In particular, the walls 15 and 17 represent at least partially the housing walls of the housing 2.

[0036] It can be seen that the bulge 15, in particular the bulge plateau 18, is formed on the inlet 19 of the cable opening 13. The cable opening 18 is thus formed with a corresponding bottleneck at its inlet 19.

[0037] Furthermore, it can be seen that the outer wall 16 is arranged spaced apart from the guide element 12. In particular, it is arranged spaced apart from the contact surface 20 of the semi-cylindrical barrel section 21 of the guide element 12. By this adjacent arrangement between the barrel section 21 and the outer wall 16, a specifically shaped guide duct 22 for the cable 11 is also formed. In particular, an S-shaped region of the cable 11 can thus be formed and the cable 11 can be laid in a defined manner from the guide element 12 upwards towards the cable opening 13.

[0038] In addition, from Figure 1 It can also be seen that the outer wall 16 comprises an outer edge 23. This outer edge 23 faces away from the cable opening 13. Observed in the height direction, the outer edge 23 in this embodiment also represents the lowest point of the outer wall 16. On this outer edge 23, an integral molding, in particular by bending, a rod 24 inclined in this respect is integrally molded. The inclined rod 24 protrudes downward in a cantilevered manner. In particular, this rod 24 is a dripping edge for liquids and / or a splash-proof element for liquids. Therefore, it is avoided that, for example, splashing water may reach the cable opening 13 from the outside of the housing 2. In addition, for example, liquid flowing downward via the cable 11 can drip via this rod 24 and therefore will not reach the cable opening 13 via the outer wall 16.

[0039] like Figure 1 As shown, the guide element 12 , in particular the cylinder section 21 , is formed in a semi-cylindrical shape.

[0040] Furthermore, in the embodiment, the guide element comprises two guide walls 25 and 26. They are molded opposite each other on the cylinder segment 21, in particular a semi-cylindrical cylinder segment 21. They extend further outwards in the radial direction of the cylinder geometry than the cylinder segment 21, in particular the contact surface 20. Thus, the guide element 12 is configured in the form of a cable drum.

[0041] In an embodiment, it is conceivable that the guide element 12 comprises an anti-lost element 27. This may be an anti-lost pin, such as Figure 1 In this embodiment, the anti-loss element 27 extends from the guide wall 25 toward another guide wall 26. This prevents the cable 11 from radially sliding out of the cylindrical section 21.

[0042] exist Figure 2 In the Figure 1 1 , in which a perspective view from below of the cable 11 on the guide element 12 is shown, and the rod 24 can also be seen.
