Description

TECHNICAL FIELD

[0001] The present invention relates to a vehicle electronics module. BACKGROUND

[0002] From US 10117357 B2 a cooling plate and vapor chamber for line cooling of one or more circuit boards in a housing of a printed circuit (PCB) are known. The cooling plate can comprise a flat surface at an oblique angle with respect to an axis along which the circuit board assembly is inserted into the housing. SUMMARY

[0003] The present invention is based on the object of providing a vehicle electronics module having an improved device for cooling electronic units.

[0004] This object is solved by the subject matter of the independent claims. Advantageous developments of the invention are defined by the dependent claims, the following description and the figures.

[0005] A first aspect of the present invention relates to a vehicle electronics module having a housing, a first electronic unit and a second electronic unit, a cooling unit and a moving device. The housing is formed for receiving a plurality of discrete electronic units and for receiving at least one discrete cooling unit for cooling the electronic units. The first electronic unit and the second electronic unit are arranged detachably in the housing. The cooling unit is arranged in the housing between the first electronic unit and the second electronic unit. By means of the moving device, a first relative movement between the first electronic unit and the cooling unit can be performed, such that in a first positioning state of the first electronic unit the cooling unit is arranged spaced apart from the first electronic unit in the housing and in a second positioning state of the first electronic unit the cooling unit and the first electronic unit are pressed against each other in the housing. By means of the moving device, a second relative movement between the second electronic unit and the cooling unit can be performed, such that in a first positioning state of the second electronic unit the cooling unit is arranged spaced apart from the second electronic unit in the housing and in a second positioning state of the second electronic unit the cooling unit and the second electronic unit are pressed against each other in the housing. The moving device comprises an actuation system. By actuation of the actuation system, the first relative movement and / or the second relative movement can be selectively generated.

[0006] In particular, both the first and the second relative movement or only the first relative movement or only the second relative movement can be generated by actuation of the actuation system. The first relative movement occurs between the first electronic unit and the cooling unit. The second relative movement occurs between the second electronic unit and the cooling unit.

[0007] Thus, an ensemble of the first and the second electronic unit and the cooling unit is formed, which can be moved in various ways from each other as required to flexibly generate various coupled and decoupled states for sufficient cooling.

[0008] In various embodiments, the vehicle electronics module can comprise one or more further assemblies each having a further first electronics unit, a further second electronics unit and a further cooling unit. Herein and hereinafter explanations regarding the assemblies and the respective embodiments described herein and hereinafter can optionally be transferred analogously to the other assemblies.

[0009] By arranging the cooling units between the electronics units, they can be arranged in a space-saving manner in the housing. By the possibility of selectively performing the first or second relative movement by means of the movement device, the first electronics unit and the second electronics unit can be sufficiently cooled.

[0010] The first positioning state of the first electronics unit can be referred to as decoupled state of the first electronics unit, in particular, while the second positioning state of the first electronics unit can be referred to as coupled state of the first electronics unit. The first positioning state of the second electronics unit can be referred to as decoupled state of the second electronics unit, in particular, while the second positioning state of the second electronics unit can be referred to as coupled state of the second electronics unit. For example, the first electronics unit and the second electronics unit can be in the same state at the same time, i.e. in the coupled state or in the decoupled state. It is also possible that the first electronics unit is in the coupled state while the second electronics unit is in the decoupled state. The positioning state of the respective electronics unit is related to the distance between the cooling unit and the respective electronics unit, in particular, and is independent of the movability of the respective electronics unit or the cooling unit, in particular.

[0011] By actuation of the actuation system, the positioning state of the first electronics unit and the positioning state of the second electronics unit change, for example, simultaneously or offset in time.

[0012] Herein and hereinafter, the first electronics unit and the second electronics unit together can be referred to as electronics units, in particular.

[0013] In particular, the electronics units and the cooling unit are pressed against each other with a predetermined pressure in the respective second positioning state. In particular, the electronics units can be removed from the housing in the respective first positioning state. Thereby, the electronics units can be replaced as required. Thus, a simple replacement of the electronics units is allowed, in particular, in the respective first positioning state, and at the same time a high cooling power for cooling the electronics units in the respective second positioning state is allowed.

[0014] By actuation of the actuation system, in particular a linear movement, in particular a fully linear movement, of one of the electronic units along a vertical axis is initiated. The vertical axis is for example perpendicular to an insertion direction. The insertion direction is for example the direction in which the electronic units can be inserted into the housing. Optionally, the electronic units and / or the cooling unit are substantially not movable in a lateral direction perpendicular to the vertical axis and the insertion direction. In particular, the movement of the electronic units in the lateral direction is limited by the guide rails. The vertical axis can also be referred to as a height direction. In particular, the described movements and their directions can also be performed in reverse.

[0015] The electronic units are for example vehicle control devices.

[0016] In an embodiment, the movement device is configured to bring a top side of the cooling unit facing the first electronic unit into contact with the first electronic unit and to bring a second, opposite bottom side of the cooling unit facing the second electronic unit into contact with the second electronic unit.

[0017] With this arrangement of the electronic units and the cooling unit, it is possible to cool the first electronic unit and the second electronic unit with only a single cooling unit in a space-saving manner.

[0018] In an embodiment, the heat transfer element is arranged at the cooling unit on an outer side of the cooling unit facing the first electronic unit. Alternatively or additionally, the heat transfer element is arranged on an outer side of the first electronic unit facing the cooling unit.

[0019] In particular, the heat transfer element is arranged at the cooling unit on an outer side of the cooling unit facing the second electronic unit. Alternatively or additionally, the heat transfer element is arranged on an outer side of the second electronic unit facing the cooling unit.

[0020] The heat transfer element can for example be formed as a thermally conductive paste and / or a cooling pad. Thereby, the heat generated at the respective electronic unit can be dissipated to the cooling unit in an improved manner.

[0021] In particular, the pressing force between the cooling unit and the first electronic unit is greater than a simple contact in the second positioning state of the first electronic unit. Optionally, the pressing force depends on the heat transfer element used. The pressing force can also be referred to as a squeezing force, since the cooling pad is for example compressed by an amount of this force. The squeezing force to be applied is for example between 400 N and 2500 N for the cooling unit and the first electronic unit. The pressing force between the cooling unit and the second electronic unit in the second positioning state of the second electronic unit is for example equal to the pressing force between the cooling unit and the first electronic unit in the second positioning state of the first electronic unit.

[0022] In an embodiment, the housing comprises guide rails for inserting the first electronic unit and the second electronic unit into the housing such that defined insertion planes for the electronic units are formed at a distance from one another.

[0023] Alternatively, the housing may include additional guide rails for inserting the cooling unit into the housing, particularly for the cooling unit only.

[0024] Specifically, the electronic units and / or cooling units are arranged in parallel on various planes within the housing. Guide rails or additional guide rails facilitate the reception and / or removal of the electronic units and / or cooling units.

[0025] In one embodiment, the first electronic unit includes a unit housing onto which a cooling unit is pressed. Specifically, the cooling unit is pressed against the underside of the unit housing of the first electronic unit. Specifically, the bottom side of the unit housing faces the cooling unit. Alternatively or additionally, the second electronic unit includes a separate unit housing onto which the cooling unit is pressed. Specifically, the cooling unit is pressed against the top side of the unit housing of the second electronic unit. Specifically, the top side of the separate unit housing faces the cooling unit. The unit housing protects the electronic unit from contamination and environmental impact.

[0026] It is feasible for the first electronic unit and / or the second electronic unit, particularly the corresponding unit housing, to include a circuit board. For example, the circuit board is thermally coupled to the unit housing via a thermally conductive material and a base. This forms a direct thermal path from the circuit board through the thermally conductive material, the base, and the unit housing, and optionally through a heat transfer element to the cooling unit. Consequently, heat is dissipated in an improved manner.

[0027] In one embodiment, the cooling unit is formed as a plate. Specifically, the plate is shaped to allow the cooling fluid to pass through. Due to its shape, the plate can make extensive contact with the electronic units, particularly the unit housings, thereby improving heat dissipation.

[0028] Alternatively, the cooling unit can be cooled by a cooling fluid, particularly a cooling liquid. The cooling fluid can be distributed to the cooling unit, for example, via a distributor.

[0029] In one embodiment, the actuation system includes a single actuation element. For example, the actuation element is formed as a pivot support. In this embodiment, a first electronic unit and a second electronic unit can move simultaneously when the actuation element is actuated.

[0030] In an embodiment, the relative movement is generated by pivoting the actuation elements, which are formed as a pivot bracket, in one direction. The pivot bracket can also be referred to as a lever. In particular, each pivot point of the lever is arranged on each opposite side of the housing. For example, the lever is rotatably attached to the housing at the pivot points. Thereby, it is possible, for example, that during the relative movement the electronic units are moved parallel to each other and towards each other to the cooling unit. For example, the pivot bracket is formed such that the pivot bracket prevents the removal of the first electronic unit if the cooling unit and the electronic units are in a second positioning state. The second positioning state can for example be referred to as a closed state. For example, the pivot points of the lever are connected to each other by an axis. By means of the pivot bracket, the cooling unit and the electronic units can be converted from the first positioning state to the second positioning state and vice versa in a simplified manner.

[0031] In an embodiment, the actuation system comprises a plurality of separate actuation elements. For example, the actuation elements are formed as a lifting element and a mating lifting element.

[0032] In an embodiment, the first actuation element is a lifting element and the second actuation element is a separate guide unit from the lifting element, which is displaceably arranged to the lifting element. In this embodiment, the actuation of the actuation system represents a relative movement of the lifting element with respect to the guide unit.

[0033] In an embodiment, the guide unit is a mating lifting element. For example, the lifting element is a wedge. The mating lifting element can for example be designed as a mating wedge. In particular, the wedge and the mating wedge are displaced against each other to generate the relative movement. In other words, the actuation of the actuation system can be performed by means of a displacement of the lifting element along the mating lifting element. For example, the wedge is movable by a rotating screw. Thus, the pressing force can be adjusted in a defined manner. Alternatively, the wedge is locked in a position along the mating wedge, for example by means of a screw.

[0034] For example, the lifting element and the mating lifting element are connected to each other via a transverse element. For example, the displacement of the lifting element with respect to the mating lifting element can be achieved by rotating the screw and by force transmission via the transverse element. Here, the longitudinal axis of the screw is optionally oriented perpendicular to the vertical axis. This embodiment of the actuation element can be referred to as a clamping device.

[0035] In an embodiment, the actuation element is a pin, which is obliquely oriented with respect to the vertical axis. In other words, the pin is oriented non-parallel and non-perpendicular to the vertical axis. In particular, the actuation system comprises a plurality of such pins. For example, the actuation system comprises six pins per electronic unit. In particular, the six pins are positioned in an edge region of the respective electronic unit and are directed to a center point of the respective electronic unit.

[0036] It is possible that the pin is formed as a screw and the guide channel is formed as a thread. Thereby, the pressing force can be continuously adjusted. In another example, the pin is formed corrugated such that it forms a snap connection with the guide channel having a plurality of locking positions. Thereby, the defined pressing force can be adjusted in an improved manner.

[0037] A second aspect of the application relates to a vehicle electronics module having a housing, a first cooling unit and at least one second cooling unit, an electronics unit and a movement device. The housing is formed for receiving at least one discrete electronics unit and for receiving a plurality of discrete cooling units for cooling the electronics unit. The first cooling unit and the second cooling unit are arranged detachably in the housing. The electronics unit is arranged in the housing between the first cooling unit and the second cooling unit. By means of the movement device, a first relative movement between the first cooling unit and the electronics unit can be performed such that in a first positioning state of the first cooling unit the first cooling unit is arranged spaced apart from the electronics unit in the housing and in a second positioning state of the first cooling unit the first cooling unit and the electronics unit are pressed against each other in the housing. By means of the movement device, a second relative movement between the second cooling unit and the electronics unit can be performed such that in a first positioning state of the second cooling unit the second cooling unit is arranged spaced apart from the electronics unit in the housing and in a second positioning state of the second cooling unit the second cooling unit and the electronics unit are pressed against each other in the housing. The movement device comprises an actuation system. By actuation of the actuation system, the first relative movement and / or the second relative movement can be selectively generated.

[0038] In particular, both the first relative movement and the second relative movement or only the first relative movement or only the second relative movement can be generated by actuation of the actuation system.

[0039] With this second aspect of the application, the cooling power can be adjusted, for example, sufficiently. For example, only the first cooling unit is coupled with the electronics unit. In order to increase the cooling power, the second cooling unit can then also be coupled with the electronics unit such that the electronics unit is then cooled from two opposite sides.

[0040] Thus, an ensemble consisting of the first cooling unit and the second cooling unit and the electronics unit is formed, which can be moved in different ways relative to each other as desired in order to flexibly generate different coupling states and decoupling states for sufficient cooling.

[0041] In various embodiments, the vehicle electronics module can comprise one or a plurality of further ensembles, which each have a further first cooling unit, a further second cooling unit and a further electronics unit.

[0042] The advantages and features of the embodiments of the vehicle electronics module according to the application according to the first aspect and the explanations in this regard can be transferred analogously to the vehicle electronics module of the second aspect of the application.

[0054] In Figure 1 In the following, an exemplary embodiment of a vehicle electronics module 1 according to the application within the meaning of the first aspect of the application is schematically shown. The vehicle electronics module 1 comprises a housing 2, at least one first electronics unit 3 and at least one second electronics unit 4, at least one cooling unit 5 and a mobile device 7 indicated in outline. In the shown example, two first electronics units 3 and two second electronics units 4 as well as two cooling units 5 are shown. The housing 2 is formed for receiving a plurality of discrete electronics units 3, 4 as well as for receiving at least one discrete cooling unit 5 for cooling the electronics units 3, 4.

[0055] Each cooling unit 5 together with one of the first electronics units 3 and one of the second electronics units 4 can be interpreted as an integrated body, the respective cooling unit 5 being arranged between said one of the first electronics units 3 and said one of the second electronics units 4. Such an integrated body will be described in the following, unless stated otherwise.

[0056] The first electronics units 3 are arranged detachably in the housing 2. The cooling units 5 are arranged in the housing 2 between the first electronics units 3 and the second electronics units 4. By means of the mobile device 7, a first relative movement between the first electronics units 3 and the cooling units 5 can be performed, such that in a first positioning state of the first electronics units 3, the cooling units 5 are arranged in the housing 2 spaced apart from the first electronics units 3, and in a second positioning state of the first electronics units 3, the cooling units 5 and the first electronics units 3 are pressed against each other in the housing 2. By means of the mobile device 7, a second relative movement between the second electronics units 4 and the cooling units 5 can be performed, such that in a first positioning state of the second electronics units 4, the cooling units 5 are arranged in the housing 2 spaced apart from the second electronics units 4, and in a second positioning state of the second electronics units 4, the cooling units 5 and the second electronics units 4 are pressed against each other in the housing 2. The mobile device 7 comprises an actuation system 9. By actuating the actuation system 9, the first relative movement and the second relative movement can be selectively generated. The first relative movement occurs between the first electronics units 3 and the first cooling units 5. The second relative movement occurs between the second electronics units 4 and the cooling units 5.

[0057] For example, in the second positioning state of the first electronic unit 3, the bottom side 3a of the first electronic unit 3 can directly contact the top side 5a of the cooling unit 5. In the second positioning state of the first electronic unit 3, the electronic unit 3 is particularly coupled to the cooling unit 5. In the first positioning state of the first electronic unit 3, the electronic unit 3 is decoupled from the cooling unit 5 and thus spaced apart from the cooling unit 5.

[0058] In the second positioning state of the second electronic unit 4, the top side 4a of the second electronic unit 4 can for example directly contact the bottom side 5b of the cooling unit 5. Thereby, the electronic unit 4 is particularly coupled to the cooling unit 5 in the second positioning state of the second electronic unit 4. In the first positioning state of the second electronic unit 4, the electronic unit 4 is decoupled from the cooling unit 5 and thus spaced apart from the cooling unit 5. In Figure 1 In the first positioning state of the first electronic unit 3, the electronic unit 3 is decoupled from the cooling unit 5 and thus spaced apart from the cooling unit 5.

[0059] For example, the electronic units 3, 4 can each comprise a unit housing 6. The cooling unit 5 can then particularly contact the bottom side 3a of the unit housing 6 of the first electronic unit 3 and the top side 4a of the unit housing 6 of the second electronic unit 4. For example, the circuit board 12 can be arranged in the unit housing 6, respectively. Optionally, the electronic units 3, 4 are electrically connected to each other via a board connection plug 19.

[0060] Optionally, the cooling unit 5 can be formed as a plate. For example, the cooling fluid can pass through the plate. In particular, the cooling fluid can be supplied to the plate by means of the distributor 11.

[0061] Figure 2 A detailed view of the vehicle electronics module 1 is schematically shown. For example, in Figure 2 The electronic units are shown in a decoupled state. In Figure 2 In the example shown, the actuation system 9 can comprise a plurality of individual actuation elements 14. The actuation elements 14 for example each comprise a contact surface 25 for contacting a respective electronic unit 3, 4. By actuation of a first actuation element 14a of the actuation elements 14, the first electronic unit 3 can for example be moved along the lifting path 22 in its lifting direction 13a, in particular until the first electronic unit 3 contacts the cooling unit 5 with a predetermined pressure. By actuation of a second actuation element 14b of the actuation elements 14, the second electronic unit 4 can for example be moved along the lifting path 22 in its lifting direction 13b, in particular until the second electronic unit 4 contacts the cooling unit 5 with a predetermined pressure.

[0062] In Figure 3 In a detailed view, the individual actuation elements 14 are schematically shown. For example, the actuation elements 14 are designed as wedge-shaped pieces. For example, the wedge-shaped pieces comprise a wedge bottom side 28 and a clamping screw 31. In Figure 3The mating lifting element designed to cooperate with the wedge 27 comprises a guide wedge top side 29. The mating wedge 27 can also be referred to as a guide wedge. For example, the guide wedge is fixedly connected to the housing 2. The guide wedge top side 29 can directly contact the wedge bottom side 28. By means of a loosened clamping screw 31, the wedge can be displaced relative to the guide wedge. The contact surface 25 of the wedge can directly contact the respective electronic unit 3, 4 to be cooled. In particular, the wedge can be displaced relative to the housing 2 along its longitudinal axis 15. By displacing the wedge along its longitudinal axis 15, the respective electronic unit 3, 4 can be displaced one-dimensionally in its respective lifting direction 13a, 13b. By tightening the clamping screw 31, the lifting position can be fixed, so that the displacement position of the wedge relative to the mating lifting element 27 is fixed. For example, Figure 2 The actuation system 9 shown in Figure 4 ) of the respective electronic unit 3, 4. Additionally or alternatively, the actuation elements 14 can be arranged, for example, on the longitudinal sides 20 ( Figure 4 ) of the respective electronic unit 3, 4.

[0063] Figure 4 A further embodiment of the vehicle electronics module 1 is shown in a top view, which has a further embodiment of the actuation system 9. In this exemplary embodiment, the actuation system 9 comprises a plurality of actuation elements 14. In the embodiment shown, the actuation elements 14 are formed as pins, in particular as screws 16a, 16b. The screws 16a, 16b can comprise a corner screw 16a and a further screw 16b. The corner screw 16a can be positioned, for example, in a corner region 17 of the respective electronic unit 3, 4. The corner screw 16a can be oriented obliquely to the respective lifting direction 13a, 13b. Furthermore, the corner screw 16a can be oriented obliquely towards a center point 18 of the respective electronic unit 3, 4. The further screw 16b can be positioned on a longitudinal side 20 of the respective electronic unit 3, 4. Figure 4

[0064] In particular, the screws 16a, 16b can be tightened with a predetermined torque, so that the respective electronic unit 3, 4 is pressed against the cooling unit 5 with a predetermined contact pressure.

[0065] In Figure 5 , a schematic front view of one of the electronic units 3, 4 with the actuation system 9, in particular with the actuation system 9 shown in Figure 4 , is shown exemplarily. The screw 16a can be screwed in along a rotation direction 21 in order to move the electronic unit 3, 4 along its respective lifting direction 13a, 13b.

[0066] In​Figure 6 , Figure 7 , Figure 8 and Figure 9 , embodiments of the vehicle electronics module 1 are shown schematically. In Figure 6 , Figure 7 and Figure 8 , the actuation system 9 is shown only in a summarized manner as a rod position 23a, 23b, 23c of a rod in cross section. The description of the actuation of the rod is in particular to be understood exemplarily with respect to the actuation of the actuation system 9.

[0067] In Figure 6 , the rod is in a central position 23b of the rod positions 23a, 23b, 23c. By actuating the rod along the actuation path 10a to the upper rod position 23a, the first electronics unit 3 can be moved, for example, along a lifting path 22a in its movement direction 13a to the cooling unit 5. By actuating the rod along the actuation path 10b to the lower rod position 23c, the second electronics unit 4 can be moved, for example, along a lifting path 22b in its movement direction 13b to the cooling unit 5. By counter-actuating the rod along the actuation path 10a, the first electronics unit 3 can in particular be decoupled from the cooling unit 5. By counter-actuating the rod along the actuation path 10b, the second electronics unit 4 can in particular be decoupled from the cooling unit 5.

[0068] For example, the first electronics unit 3 and the second electronics unit 4 cannot be coupled to the cooling unit 5 at the same time. In particular, the first electronics unit 3 and the second electronics unit 4 cannot be decoupled from the cooling unit 5 at the same time.

[0069] In the embodiments shown in Figure 6 and Figure 7 , the first electronics unit 3 and the second electronics unit 4 can be selectively coupled to the cooling unit 5, for example.

[0070] In Figure 7 , the rod can be in the upper rod position 23a, for example. By actuating the rod along the actuation path 10a to the central position 23b, the first electronics unit 3 can be moved to the cooling unit 5, for example. By further actuating the rod along the actuation path 10b until the lower rod position 23c, the second electronics unit 4 can be moved to the cooling unit 5. By counter-actuation of the rod, the second electronics unit 4 can in particular first be decoupled from the cooling unit 5 and then the first electronics unit 3.

[0071] For example, the first electronics unit 3 and the second electronics unit 4 can be coupled to the cooling unit 5 at the same time. In particular, the first electronics unit 3 and the second electronics unit 4 can be decoupled from the cooling unit 5 at the same time. In particular, the coupling and / or decoupling is realized offset in time.

[0072] In Figure 8In the embodiment shown, coupling of the first electronic unit 3 and the second electronic unit 4 can be achieved simultaneously, for example, by actuating the lever from the upper lever position 23a to the lower lever position 23c. In particular, decoupling of the first electronic unit 3 and the second electronic unit 4 can also be achieved simultaneously by counter-actuating the lever from the lower lever position 23c to the upper lever position 23a.

[0073] Figure 9 An embodiment of a vehicle electronic module 1 is shown which is within the meaning of the second aspect of the application. In this embodiment, the electronic unit 3 is arranged between two cooling units 5. One or more further electronic units can be optional for this embodiment. In this embodiment, the housing 2 is formed for receiving the electronic unit 3 and for receiving the cooling units 5 for cooling the electronic unit 3. The electronic unit 3 is arranged in the housing 2 detachably. The electronic unit 3 is arranged in the housing 2 between the cooling units 5. By means of a movement device, a relative movement between the electronic unit 3 and the cooling units 5 can be performed, such that in a first positioning state the cooling units 5 are arranged spaced apart from the electronic unit 3 in the housing 2 and in a second positioning state the cooling units 5 and the electronic unit 3 are pressed against each other in the housing 2. The movement device 7 comprises an actuation system 9. By actuating the actuation system 9, a first relative movement and a second relative movement are selectively generated. The first relative movement occurs between the electronic unit 3 and a first cooling unit of the cooling units 5. The second relative movement occurs between the electronic unit 3 and a second cooling unit of the cooling units 5.

[0074] In particular, Figures 1 to 8 The embodiment shown in Fig. 2 is considered to be a similar embodiment of the variant shown in Fig. 1. Figure 9 The embodiment shown in Fig. 2 is considered to be a similar embodiment of the variant shown in Fig. 1.
