Description

Housing comprising two housing parts, which are coupled by means of a connection device, and with a drainage channel
The invention relates to a housing for a control device of a motor vehicle, comprising a first housing part and a second housing part. In the assembled state of the housing the first housing part is coupled with the second housing part by means of a connection device and in an interior space of the housing formed by the two housing parts the control device is attachable.
From the prior art already housings for control devices are known. In particular the housing comprises a first, in particular a top housing part, and a second, in particular a bottom housing part. Into an interior space formed from the first housing part and the second housing part in particular a circuit board with in particular a control device is attachable. Moreover, the housing can comprise electric terminals, by means of which the control device for instance can be supplied with current. The first housing part and the second housing part can in particular be screwed together via screws as connection device. The housing in particular serves for protecting the control device within the housing against environmental influences such as for instance dust and/or water. In particular at the places, in which the connection device, in particular the screws are arranged on the housing, however, it is difficult to achieve a high tightness, in particular against water, since in particular at these places water can enter the housing.
It is the task of the present invention to create a housing, which has an improved tightness against water entering into the housing.
This task is solved by a housing according to the independent claim.
One aspect of the invention relates to a housing for a control device of a motor vehicle. The housing has a first housing part and a second separate housing part. In the assembled state of the housing the first housing part is coupled with the second housing part by means of a connection device. In an interior space, which is formed by the two housing parts, the control device is attachable.
At least one of the two housing parts on an outer side of the housing facing away from the interior space comprises a drainage channel. In the assembled state of the housing the drainage channel at least in portions is configured in a transition area from the first housing part to the second housing part.
By means of the drainage channel water, which has splattered or flown onto the housing parts, can be reliably transported away from the housing. In particular in the drainage channel the water can be collected on the housing and correspondingly be drained off so that in particular by means of the drainage channel water can be conducted away from places that are at risk of being invaded by water. These places concern in particular the connection device, which in particular are screws. In other words, by the drainage channel the water can be conducted away from the connection device so that little water, in particular no water, reaches the connection device and can enter the housing, in particular invade the interior space of the housing and reach the control unit. Thereby, a reliable operation of the control device is realized, since less water, in particular no water, can enter the interior space. A raised tightness of the housing is realized so that no water can enter the housing and in particular reach the control unit.
According to an advantageous embodiment in an assembled state the first housing part can comprise the drainage channel and the second housing part can at least partly plunge into the first housing part, in particular partly into the drainage channel. In particular thereby a large contact surface between the first housing part and the second housing part can be realized. Moreover, thereby in particular water, which is present at the second housing part, can be introduced advantageously into the drainage. In particular by the plunging into the first housing part thus the contact surface between the first housing part and the second housing part can be increased, whereby an
advantageous tightness is effected.
It has further turned out to be advantageous, if the second housing part comprises an elevation, which plunges into the first housing part, in particular into the drainage channel, and/or in the assembled state of the housing a sealing element is arranged between the elevation and a first end of the drainage channel. Thereby it is in particular facilitated that a raised tightness between the first housing part and the second housing part is effected. In particular the sealing element can further seal the housing between the housing parts. In particular by the elevation on the second housing part the contact surface between the sealing element and the first housing part can be further enlarged so that advantageously the housing in the assembled state can be sealed. According to a further advantageous embodiment the drainage channel can be designed to be U-shaped. In particular by the U-shape the water can advantageously drain off in the drainage channel. Moreover by the U-shape a large reception capacity for receiving water within the drainage channel can be provided. Thereby it is in particular facilitated that a large quantity of water can be conducted through the drainage channel and in particular be conducted away from the housing and thus in particular from the control device. Thereby also in the case of a large quantity of water, same can reliably flow off and the housing thereby be reliably protected against water entering. A raised tightness of the housing is provided so that the control device is protected better against
environmental influences, in particular against water.
It is equally advantageous if the first housing part comprises the drainage channel and the first housing part is designed to be essentially pan-shaped, wherein the drainage channel is configured on at least two, in particular three, outer sides of the first housing part.
Through the pan-shaped setup of the first housing part in particular an interior space can be created so that the control unit can be advantageously arranged in the interior space. In particular then on at least two, in particular on three, outer sides of the first housing part the drainage channel can be "passed around". In particular thereby it is facilitated, since in particular the connection device is arranged at the corners of the pan-shaped first housing part, that water advantageously can be led away from these corners and conducted into the drainage channel. In particular on a fourth side, on which there can be electrical terminals for the control device, in other words the plug contacts can be situated, the drainage channel is not configured. It may then be envisaged that the drainage channel ends on the fourth side and the water on the fourth side can flow off from the drainage channel. Thereby the housing can advantageously be drained so that in particular no water can enter the interior of the housing.
It is equally advantageous if in the assembled state the housing of the drainage channel is arranged on three outer sides of the pan-shaped first housing part and the housing on a fourth outer side of the first housing part comprises at least one opening, which forms a drain of the drainage channel, so that water can flow out of the at least one opening. In particular the first housing part comprises two openings so that the two ends of the drainage channel corresponds with the two openings and on the two ends of the drainage channel the collected water can drain off. In particular then both openings are configured on the fourth side of the first housing part. Thereby advantageously the water can flow from the housing through the openings so that the control device in the interior space is advantageously protected against water, since via the connection device no water can invade the interior space.
According to a further advantageous embodiment on an outer surface of the second housing part facing away from the interior space a plane of the second housing part and at least one edge of the second housing part can be configured and the second housing part in the area of the plane have a first thickness and in the area of the edge have a second thickness that is larger than the first thickness, wherein the second housing part in particular is attachable on the at least one edge on the first housing part. Thereby, it is facilitated that water, in particular in the plane, is collected and is conducted from the plane into the drainage channel. The edge in particular comprises the connection device and is configured to be elevated so that the water collects in the plane and cannot enter via the connection device into the interior space of the control device. Thereby, the control device can be better protected against water.
It is further advantageous if the second housing part on at least one outer surface of the second housing part comprises at least one, in particular two, ramp(s) elevating from the plane to the edge of the second housing part and is connected with the drainage channel so that water can be conducted from the plane into the drainage channel. Thereby it is facilitated that the water is conducted from the plane into the drainage channel via the ramps. Thereby the water can be taken from the plane into the drainage channel and thereby the plane can be drained. Thus, advantageously the water can be conducted from the plane into the drainage channel, wherein by means of the drainage channel again the water can flow off the housing. Thereby a raised tightness of the housing can be given since the water can advantageously drain off through the drainage channel from the plane via the ramps.
It has further turned out to be advantageous if the second housing part on the outer surface on at least one outer side of the second housing part comprises a water conduction element, which extends from the edge of the second housing part at least partly into the plane, wherein the water conduction element on at least one end of the water conduction element is connected with the ramp and conducts water from the plane to the ramp. Thereby an improved flow of water towards the ramp can be realized so that the water from the ramp can be advantageously conducted towards the ramp, which in turn is connected with the drainage channel. Thereby, in an improved way water can be conducted from the plane to the ramp via the water conduction element and from the ramp into the drainage channel and from the drainage channel away from the housing. Thereby the housing can be better protected against water entering the interior space.
According to a further advantageous embodiment the second housing part in the plane can comprise an indentation, which conducts water from the plane to the ramp. In particular the indentation can be configured as groove and thereby a further guidance for the water within the plane can be provided so that the water is conducted from the plane via the indentation towards the ramp and from the ramp again into the drainage channel. Thereby an enhanced drainage of the plane can be performed.
According to a further advantageous embodiment the second housing part on the outer surface may comprise an arch element, which extends from a first end of a side, in particular a fourth side of the second housing part, which corresponds with a fourth outer side of the first housing part, towards a second end of this side in an arch-like manner into the plane. In particular the fourth side of the second housing part thus is assigned the fourth side of the first housing part in the assembled state. In particular on the fourth side of the first housing part and the second housing part the electrical connections are situated. Then the water in the plane can be separated by the arch element and by the arch element the water can be directly, in other words without being led to the drainage channel, flow out next to the electrical connections. By the arch-like design of the arch element further a guidance of the water can be provided so that the water at predefined places flows off the second housing part.
It is equally advantageous if the arch element divides the plane into two sub-planes, wherein the water flows from a first sub-plane into the drainage channel, and water from the second sub-plane, via a further opening, in particular on the fourth side of the second housing part, drains off directly. Thereby it is facilitated that water from the first sub-plane can flow for instance via the ramps into the drainage channel and from the second sub- plane directly, in other words without being led via the drainage channel, can drain off on the fourth side. Thereby an improved tightness of the housing is given.
It has further turned out to be an advantage if in the second sub-plane at least one further water conduction element is arranged, which conducts the water from the second sub- plane in the direction of the further opening. Thereby within the second sub-plane a further water guidance can be realized so that the water advantageously can be guided in the direction towards the and from the further opening and can thereby can better drain off from the housing. According to a further advantageous embodiment the second housing part on the outer surface can comprise yet a further, in particular triangular water conduction element, which is arranged on one side, in particular on a side opposite the fourth side, of the second housing part, and conducts water from the plane in the direction of the drainage channel. Thereby it is facilitated that also on the side opposite the fourth side a water conduction element is arranged, which can conduct the water again in an advantageous way into the drainage channel and thereby can drain the plane.
It is further advantageous if the second housing part on the outer surface comprises at least one partition element, which separates the plane and a connection plane, which is configured to be elevated in particular relative to the plane, wherein in the connection plane a connection element of the connection device is arranged. In other words the connection plane of the connection device is situated elevated relative to the plane so that water of the plane cannot flow towards the connection plane. The water of the plane is separated by the corresponding partition elements from the connection plane so that a connection element, for instance a screw, does not get into contact with the water.
Thereby via the connection element of the connection device no water can invade the interior space of the housing so that the control device is protected against water in the interior space of the housing.

Fig. 1 shows a housing 1 in an exploded view. The housing 1 comprises a first housing part 2 and a second housing part 3. The housing 1 is configured to receive a control device 4, which is in particular arranged on a circuit board 5, in an interior space 6 of the housing 1 . In particular it may be envisaged that by means of screw elements 7 the circuit board 5 with the control device 4 is arranged on the second housing part 3. Moreover, at least one electric connection point 8, in particular several electrical connection points 8, for the electric coupling of the control device 4 are envisaged on the circuit board 5. The first housing part 2 and the second housing part 3 are screwed together via a connection device 9, which in particular is configured from various connection elements 10, and the housing 1 can thereby be transferred into the assembled state. In the assembled state the housing 1 has a high tightness so that the control unit 4 is protected against environmental influences, in particular against water. It can therein be envisaged that the electrical connection points 8 are arranged outside the housing 1 . These can then equally have a tightness so that no water can enter the interior space 6 of the housing 1 . Fig. 2 shows a schematic view of the housing 1 in the assembled state. In particular Fig. 2 shows an outer side 1 1 of the housing 1 , which faces away from the interior space 6. Further, Fig. 2 shows a transition area 12, which is configured in the assembled state between the first housing part 2 and the second housing part 3. The first housing part 2 comprises a drainage channel 13, which in the assembled state of the housing 1 is configured at least in portions in the transition area 12 of the first housing part 2 to the second housing part 3. In particular it is envisaged that the second housing part 3 at least partly plunges into the first housing part 2, in particular into the drainage channel 13, in particular partly. Thus, between the first housing part 2 and the second housing part 3 a high tightness can be achieved so that no water, in particular splatter water, can invade the interior space 6 of the housing 1 .
The first housing part 2 in the present case comprises a first side 14 of the first housing part 2, a second side 15 of the first housing part 2, a third side 16 of the first housing part 2 and a fourth side 17 of the first housing part 2. In particular therein the first housing part 2 is configured to be pan-shaped. The drainage channel 13 is in particular configured on at least two, in particular three sides 14, 15, 16, 17 of the first housing part 2.
In the present embodiment the drainage channel 13 is arranged on three sides 14, 15, 16, 17 of the first housing part 2. In particular the drainage channel 13 in the present case is configured on the side 14, on the side 15, and on the side 16.
On the fourth side 17 in particular at least one, presently two openings 18 are configured, which correspond with the drainage channel 13 so that water can flow from the drainage channel 13 out of the openings 18.
On an outer surface 19 of the second housing part 3, which faces away from the interior space 6, a plane 20 of the second housing part 3 is configured. Moreover, at least one edge 21 , presently two edges 21 , are configured on the second housing part 3 on the outer surface 19. In the area of the plane 20 the second housing part 3 has a first thickness, and in the area of the edge 21 the second housing part 3 has a second thickness, which is designed larger in comparison with the first thickness. It may be envisaged that the second housing part 3 on the at least one edge 21 is attachable on the first housing part 2.
Fig. 3 shows a cross-sectional view of a section of the housing 1 . Fig. 3 shows that the second housing part 3 comprises an elevation 22, which plunges into the first housing part 2, in particular into the drainage channel 13. In the assembled state of the housing 1 between the elevation 22 of the second housing part 3 and a first end 23 of the drainage channel 13, in particular the first housing part 2, a sealing element 24 can be arranged. By means of the sealing element 24 a raised tightness between the first housing part 2 and the second housing part 3 in the assembled state can be realized. In particular from Fig. 3 it can be seen that the drainage channel 13 is in particular configured to be U- shaped.
Fig. 4 shows a schematic view of the second housing part 2. The outer surface 19 of the second housing part 2 is shown. In Fig. 4 by the arrows 25 the directions, in which the water flows on the outer surface 19, are shown.
Fig. 4 shows that the second housing part 3 on the at least one outer surface 19 comprises at least one ramp 26. In the present case the second housing part 3 comprises four ramps 26. In particular therein the ramps 26 elevate from the plane 20 towards the edges 21 . In the assembled state the ramps 26 are connected with the drainage channel 13 so that water along the arrows 25 can be conducted from the plane 20 into the drainage channel 13 via the ramps 26.
The ramps 26 presently are configured on a second side 30 and on a third side 31 of the second housing part 3.
In the assembled state a first side 32 of the second housing part 3 corresponds with the first side 14 of the first housing part 2, the second side 30 of the second housing part 3 with the second side 15 of the first housing part 2, the third side 31 of the second housing part 3 with the third side 16 of the first housing part 2, and the fourth side 29 of the second housing part 3 with the fourth side 17 of the first housing 2 part.
Moreover, Fig. 4 shows that the second housing part 3 on the outer surface 19 comprises an arch element 27, which from a first end 28 extends on a fourth outer side 29 of the second housing part 3 to a second end 28' and therein extends arch-like into the plane 20.
The arch element 27 in the present embodiment divides the plane 20 into two sub-planes 20' and 20". It is envisaged that water from the first sub-plane 20' drains or flows off into the drainage channel 13 and water from the second sub-plane 20" drains off via at least one further opening 33, which is configured in particular on the fourth side 29 of the second housing part 3. Moreover it is envisaged that in the second sub-plane 20' a further water conducting element 34 is configured, which conducts the water from the second sub-plane 20" in the direction of the further opening 33. The further water conducting element 34 is presently formed by two bar-like elevations 35, which comprise an opening, through which the conducted water then can be led in the direction of the further opening 33.
In Fig. 4 it can further be seen that the second housing part 3 on the outer surface 19 comprises yet a further, in particular triangular water conducting element 36, which presently is arranged on the first side 32 of the second housing 3. Therein water can be conducted from the plane 20, or from the first sub-plane 20' in the direction of the drainage channel 13. Moreover in Fig. 4 at least one partition element 37, presently four partition elements 37, can be seen, which separates the connection elements 10 from the plane 20 so that no water is conducted in the direction of the connection elements 10.
Fig. 5 shows a schematic perspective view of the second housing part 3 in a partial section of the second housing part 3. In Fig. 5 the plane 20 can be seen in a perspective view. In the present embodiment the second housing part 3 on the outer surface 19 on at least one side, presently on the second side 30 of the second housing part 3, comprises a water conducting element 38, which extends from the edge 21 at least partly into the plane 20. The water conduction element 38 is connected at least on one end 38' of the water conduction element 38 with the ramp 26. In the present example the water conduction element 38 is at least essentially configured to be triangular and is coupled with the respective ends 38' with a respective ramp 26. Thereby water can be conducted from the plane 20 in the direction of the ramps 26.
Moreover, Fig. 5 shows that the second housing part 3 in the plane 20 comprises an indentation 39, which conducts water from the plane 20 to the ramp 26. The indentation 39 is in particular configured as a groove.
From Fig. 5 further it can be seen that the partition element 37 separates the plane 20 and a connection plane 40, which is configured to be elevated in particular relative to the plane 20, from the plane 20, wherein on the connection plane 40 the connection elements 10 are arranged. Thereby it can be prevented that water from the plane 20 reaches the connection plane 40, in particular the connection elements 10, and thereby can possibly enter the interior space 6 of the housing 1 .
