Description

Technical Field

[0001] The present disclosure relates to an automotive electronic control unit including at least one circuit board. Background Art

[0002] Such electronic control units (also referred to as "ECUs") are well known in the art and can be used in vehicles for various applications. Typical examples of devices controlled by the electronic control unit include motors, steering devices, door lock systems, devices for autonomous driving, etc.

[0003] To avoid electromagnetic interference to other electronic components, the electronic control unit typically includes electromagnetic shielding that shields at least some of the electronic components on the circuit board.

[0004] Typical electromagnetic shielding can be formed, for example, by a shielding cover connected to the circuit board and covering the electronic components to be shielded. The shielding cover may include a cover plate located on the side opposite to the circuit board.

[0005] However, this electromagnetic shielding design requires assembling multiple components, which increases the assembly workload and cost.

[0006] Therefore, it is necessary to facilitate the assembly of the automotive electronic control unit. Summary of the Invention

[0007] An automotive electronic control unit includes a simplified arrangement achieved by the features of claim 1.

[0008] The arrangement of the automotive electronic control unit can be simplified based on the following concept: in an automotive electronic control unit including two circuit boards, the already available circuit boards are used to cover the electromagnetic shielding wall from both sides. In other words, one of the circuit boards is used instead of the cover plate to cover the electromagnetic shielding wall connected to the other circuit board. The circuit board and the electromagnetic shielding wall together form a shielding space disposed between the circuit boards, wherein the shielding space houses the electronic components disposed on at least one of the circuit boards. Therefore, the first circuit board, the second circuit board, and the electromagnetic shielding wall define the boundaries of the shielding space. Thus, the need for an additional cover plate is eliminated.

[0009] Therefore, the automotive electronic control unit is simplified such that as few components as possible are required for its assembly, which also has a beneficial effect on cost reduction.

[0010] Furthermore, by connecting the circuit board to the electromagnetic shielding wall, the overall size of the automotive electronic control unit can be reduced. The resulting compact design of the automotive electronic control unit (which may also be referred to hereinafter as the "control unit") enables the use of the automotive electronic control unit in a limited space environment. However, at the same time, the component placement space on the circuit board is increased.

[0011] Further advantages will become apparent from the description, the dependent claims, and the drawings.

[0012] Specifically, the first circuit board and the second circuit board may each include a layer of electromagnetic shielding material.

[0013] For example, the electromagnetic shielding material may be selected from at least one of copper, nickel, silver, iron, tin, or an alloy thereof (such as brass or steel, particularly spring steel).

[0014] If the shielding wall and / or the shielding layer are formed as a single piece, sufficient electromagnetic shielding can be achieved, thereby allowing for cost-effective production of the shielding wall and / or the shielding layer.

[0015] However, sufficient electromagnetic shielding can also be achieved if the shielding wall and / or the shielding layer are perforated. Such perforations reduce weight and can save materials. Preferably, the shielding wall and / or the shielding layer are perforated in a manner that forms a mesh.

[0016] The perforations in the shielding wall and / or the shielding layer can form cavities or openings. Preferably, the maximum opening size of the cavities formed in the shielding wall and / or the shielding layer is at least 1 mm, preferably at least 2 mm, and most preferably at least 5 mm. Such a size of the cavities still allows for sufficient electromagnetic shielding to be achieved.

[0017] It should also be noted that the cavities or openings can also refer to the space formed between two protrusions extending from the edge of the shielding wall and / or the shielding layer.

[0018] Preferably, the shielding wall is formed from a bent metal sheet, particularly a stamped and bent metal sheet, which allows for convenient and cost-effective production of the shielding wall.

[0019] The shielding wall can be physically connected to the corresponding circuit board to form a stable arrangement of the automotive electronic control unit.

[0020] Furthermore, the shielding wall can be electrically connected to the corresponding shielding layers of the first circuit board and the second circuit board.

[0021] To connect the shielding wall to the corresponding circuit board, the first circuit board and the second circuit board can each include a connection side, where the shielding wall is connected to the first circuit board and the second circuit board at the corresponding connection sides.

[0022] The connection side of the circuit board can also serve as an electrical contact portion between the corresponding shielding layer of the circuit board and the shielding wall.

[0023] The shielding wall can be connected to the corresponding circuit board at the connecting side by at least one of form fit, force fit, and material bond, in particular by material bond including soldering.

[0024] The shielding wall can be connected to the first circuit board and the second circuit board in the same or different ways. Specifically, the shielding wall can be connected to the first circuit board and the second circuit board in the same way by either material bond or force fit. Alternatively, the shielding wall and the first circuit board can be connected by material bond, while the shielding wall and the second circuit board can be connected by force fit.

[0025] The force fit connection can be achieved by at least one spring elastic connection device. The spring elastic connection device can be formed as spring arms extending from the edge of the shielding wall. In the assembled state of the automotive electronic control unit, the spring arms can be received in corresponding holes formed at the connecting side of the circuit board.

[0026] However, the spring elastic connection device can also include at least one retaining clip attached to the circuit board to form a connection side for the shielding wall. Specifically, the retaining clip can include two spring arms, and in the assembled state of the control unit, the shielding wall is received between the spring arms of the retaining clip.

[0027] In addition, the spring elastic connection device can be formed by a retaining wall that at least partially surrounds the shielding wall or is at least partially surrounded by the shielding wall. When the shielding wall is connected to the retaining wall, at least one spring arm formed at the retaining wall presses against the shielding wall. Preferably, if the retaining wall surrounds the shielding wall, the spring arms of the retaining wall can press against the outer surface of the shielding wall. However, if the shielding wall surrounds the retaining wall, the spring arms of the retaining wall can press against the inner surface of the shielding wall.

[0028] According to one embodiment, the shielding wall includes at least one protrusion extending from the edge facing the printed circuit board to which the shielding wall is connected. The protrusion can be received in a corresponding hole formed at the connecting side of the circuit board. In addition, the protrusion of the shielding wall received in the hole of the circuit board can be fixed by material bond. For example, the protrusion received in the hole can be fixed by soldering.

[0029] Generally, the shielding wall can be mounted to at least one of the first circuit board and the second circuit board by being inserted into at least one hole formed at the corresponding connecting side.

[0030] Additionally or alternatively, the shielding wall may be mounted to at least one of the first circuit board and the second circuit board by at least one spring element, in particular by pressing the spring element against the shielding wall to mount it to at least one of the first circuit board and the second circuit board.

[0031] It should be noted that the shielding wall may be electrically connected to the corresponding shielding layer through holes and / or spring elements at the connection side of the corresponding circuit board.

[0032] According to one embodiment, the shielding wall may be formed as a single piece, thus allowing for cost-effective production of the shielding wall.

[0033] According to another embodiment, the shielding wall at least includes a first wall segment and a second wall segment, wherein the first wall segment is connected to the first circuit board and the second wall segment is connected to the second circuit board.

[0034] This allows the wall segments of the shielding wall to be easily pre-assembled to the corresponding circuit boards, such that when the circuit boards are combined, the shielding wall is formed. Additionally, when disassembling the circuit boards, the separate wall segments allow easy access to the electronic components. This is advantageous for both assembling the electronic components and maintenance purposes.

[0035] To provide sufficient electromagnetic shielding, the first wall segment may surround at least a portion of the second wall segment, in particular circumferentially surround at least a portion of the second wall segment.

[0036] In the assembled state, the first wall segment and the second wall segment may be in contact with each other. However, according to another embodiment, the first wall segment and the second wall segment may not be in contact, in particular not in electrical contact.

[0037] Preferably, the first circuit board and the second circuit board of the automotive electronic control unit are arranged parallel to each other, in particular arranged in such a way that their corresponding connection sides face each other. In this configuration, the distance between the circuit boards connected by the shielding wall may be in the range of 1 millimeter to 10 millimeters, preferably in the range of 2 millimeters to 8 millimeters, for example between 3 millimeters and 5 millimeters.

[0038] It should be noted that the shape of the shielding wall may also be designed such that the first circuit board and the second circuit board may be arranged at an angle relative to each other, for example, at a 90° angle.

[0039] Preferably, the automotive electronic control unit is used to control various parts of the vehicle, in particular the motor and the steering device. However, the automotive electronic control unit disclosed herein may also be used to control other parts of the vehicle, such as but not limited to door lock systems, human-machine interfaces, telecommunication devices, powertrains, speed control units, brake modules, battery management systems, devices for autonomous driving, etc.

[0040] The electronic component to be shielded may be selected from at least one of a processor, a processing unit, at least one storage unit, and at least one non-transitory data memory. However, other electronic components may also be shielded.

[0041] In addition, the automotive electronic control unit may include a camera. Preferably, the camera is disposed at one of the first circuit board and the second circuit board, particularly on the side opposite to the shielding wall of the corresponding first circuit board and the second circuit board. Specifically, the camera may be arranged on the side of the corresponding first circuit board and the second circuit board that forms the outer side of the automotive electronic control unit, such that the camera faces the outer side of the automotive electronic control unit.

[0050] Figure 8 schematically shows Figure 7 a cross-sectional view of the control unit of DETAILED DESCRIPTION

[0051] Various embodiments of an automotive electronic control unit are shown in the figures. The automotive electronic control unit (which may also be simply referred to as the "control unit") can be used to control various parts of an automobile, such as an electric motor or a steering device.

[0052] Each of the control units described below includes a first circuit board 10 and a second circuit board 12.

[0053] At least one of the circuit board 10 and the circuit board 12 includes electronic components to be electromagnetically shielded. For the sake of simplicity, the electronic components are not shown in the drawings.

[0054] The electronic components can be at least one selected from a processor, a processing unit, at least one storage unit, or at least one non-transitory data memory.

[0055] For the purpose of achieving electromagnetic shielding, the control unit includes an electromagnetic shielding wall 14, which together with the first circuit board 10 and the second circuit board 12 forms a shielding space 16 ( Figure 2 , Figure 4 , Figure 6 and Figure 8 ).

[0056] The shielding space 16 is arranged between the first circuit board 10 and the second circuit board 12 and the inner side of the shielding wall 14.

[0057] In addition, the shielding space 16 houses the electronic components of at least one of the first circuit board 10 and the second circuit board 12.

[0058] The shielding wall 14 of the embodiment shown in the figure includes an electromagnetic shielding material and is made of a stamped and bent metal sheet, such as copper, nickel, silver, iron, tin, or an alloy thereof (such as brass or steel, especially spring steel).

[0059] In addition, the materials forming the circuit boards 10, 12 can also perform electromagnetic shielding. However, in order to enhance the electromagnetic shielding performance of the circuit boards 10, 12, the circuit boards 10, 12 can include a shielding layer (not shown) of an electromagnetic shielding material.

[0060] The electromagnetic shielding material of the shielding layer can be the same as the electromagnetic shielding material used for the shielding wall 14. Alternatively, the shielding layer and the shielding wall 14 can use different electromagnetic shielding materials. It should be noted here that the electromagnetic shielding materials of the shielding layers for the respective circuit boards 10, 12 can be the same or different.

[0061] The following will be further described in detail with specific embodiments. The shielding wall 14 is connected to the circuit boards 10, 12 at the connection sides 18, 20 respectively formed at the circuit boards 10, 12.

[0062] The connection sides 18, 20 are also used to electrically connect the shielding wall 14 to the corresponding shielding layers of the first circuit board 10 and the second circuit board 12. It should be understood that in this case, the connection sides 18, 20 are conductive and are electrically connected to the corresponding shielding layers.

[0063] As can be seen from Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 In the assembled state of the control unit, the circuit boards 10 and 12 are arranged parallel to each other such that the connection sides 18 and 20 face each other.

[0064] In this configuration, the distance between the circuit boards 10 and 12 connected by the shielding wall 14 is in the range between 1 mm and 40 mm, preferably in the range between 4 mm and 20 mm, for example between 8 mm and 16 mm.

[0065] However, depending on the application, other arrangements of the circuit boards 10 and 12 can be envisaged, in which the circuit boards 10 and 12 are arranged at an angle to each other. For example, the first circuit board 10 can be arranged at an angle of 20°, 45° or 90° relative to the second circuit board 12. It should be understood that the shielding wall 14 is then formed such that the first circuit board 10 is connected to the second circuit board 12 by the shielding wall 14, thereby forming a corresponding shielding space 16.

[0066] Now turning to Figure 1 and Figure 2 , a first embodiment of the control unit will be described.

[0067] The shielding wall 14 is formed as a single-piece bent metal sheet. Specifically, the shielding wall 14 is formed as substantially one piece, only being perforated at the respective bent corners 22 of the shielding wall 14.

[0068] The perforations at the corners 22 form V-shaped cavities 24 to facilitate bending of the metal sheet at the corresponding corners.

[0069] However, the shielding wall 14 can include more cavities. Specifically, the shielding wall 14 can be perforated in segments, for example to form a mesh. In this regard, it should be noted that the maximum size of the cavities 24 and / or the maximum opening size of the cavities of the mesh is at least 1 mm, preferably at least 2 mm, and most preferably at least 5 mm.

[0070] The shielding wall 14 of the first embodiment is connected to the first circuit board 10 by a material bond such as soldering (brazing).

[0071] For this purpose, as best shown in Figure 5 shown in connection with the control unit of the third embodiment

[0072] The protrusion 26 is received in a corresponding hole (not shown) formed in the first circuit board 10. In this case, the hole defines the connection side 18 of the first circuit board 10.

[0073] To mount the shielding wall 14 to the first circuit board 10, the protrusion 26 is inserted into the hole. Subsequently, the hole is filled with a welding material, thereby bonding the shielding wall 14 to the material of the first circuit board 10.

[0074] On the opposite side, the shielding wall 14 is connected to the second circuit board 12 by a holding wall 30 connected to the second circuit board 12.

[0075] The holding wall 30 includes a plurality of spring elements 32 which are formed as spring arms 34 extending away from the holding wall 30 on a side of the holding wall 30 opposite to the side facing the second circuit board 12. In other words, the spring arms 34 extend towards the first circuit board 10 in the assembled state of the control unit.

[0076] In the assembled state, the shielding wall 14 is circumferentially surrounded by the holding wall 30 such that the spring arms 34 of the holding wall 30 bear against the outer surface of the shielding wall 14, thereby connecting the shielding wall 14 to the second circuit board 12 at the connection side 20 of the second circuit board 12 by force fit. In this case, it should be noted that the spring arms 34 are inclined inwards.

[0077] It should also be noted that the holding wall 30 may also be surrounded by the shielding wall 14 such that, in the assembled state of the control unit, the outwardly inclined spring arms 34 bear against the inner surface of the shielding wall 14.

[0078] The holding wall 30 may be part of the shielding wall 14.

[0079] To be flush with the second circuit board, the edge 28 of the shielding wall 14 facing the second circuit board 12 is flat (even) ( Figure 2 ).

[0080] It should be noted that the shielding wall 14 can be connected to either the first circuit board 10 or the second circuit board 12 in the same manner, i.e., the shielding wall 14 can be connected to the two circuit boards 10, 12 by the above-described material bonding or the above-described force fit.

[0081] Now turning to Figure 3 and Figure 4 , a second embodiment of the control unit is described. The control unit according to the second embodiment substantially corresponds to the control unit of the first embodiment.

[0082] However, the shielding wall 14 of the control unit of the second embodiment is not connected to the second circuit board 12 via the holding wall 30, but is connected to the second circuit board 12 via a plurality of holding clips 36 that are connected to the second circuit board 12 and define the connection side 20 of the second circuit board 12.

[0083] In the present embodiment, the second circuit board 12 includes six holding clips 36 ( Figure 4 ). Specifically, two holding clips 36 are respectively provided on each long side of the shielding wall 14, and one holding clip 36 is respectively provided on each short side of the shielding wall 14. However, depending on the application of the control unit and / or the size of the shielding wall 14, the number of holding clips 36 can be more or less than six, such as two, three, four, five, seven or more holding clips 36.

[0084] As Figure 4 can be seen, each holding clip 36 includes two pairs of spring arms 34. In the assembled state of the control unit ( Figure 3 ), the shielding wall 14 is received between two spring arms 34 in a pair of spring arms 34. In this case, the holding clip 36 is another example of a spring element 32 for connecting the shielding wall 14 to the circuit boards 10, 12 by force fit.

[0085] It should be noted that the shielding wall 14 can be respectively connected to each of the first circuit board 10 and the second circuit board 12 via the holding clips 36. In addition, the shielding wall 14 can be connected to at least one of the first circuit board 10 and the second circuit board 12 in at least some sections via the holding wall 30 as described with respect to the first embodiment.

[0086] Regarding Figure 5 and Figure 6 a third embodiment of the control unit is described. Except for the way in which the shielding wall 14 is connected to the second circuit board 12, the control unit of the third embodiment basically corresponds to the control unit according to the first embodiment.

[0087] In the control unit of the third embodiment, the spring element 32 is not formed at the second circuit board 12 as described with respect to the first embodiment and the second embodiment, but the spring element 32 is formed at the shielding wall 14. Specifically, the shielding wall 14 includes a plurality of spring arms 34 that project from an edge 38 of the shielding wall, which is opposite to the edge 38 of the shielding wall 14 that includes the protrusion 26 for bonding the shielding wall 14 material to the first circuit board 10.

[0088] In the assembled state of the control unit, the spring arms 34 are received in corresponding holes (not shown) present in the second circuit board 12, thereby connecting the shielding wall 14 to the second circuit board 12 by force fit. In this regard, the holes form the connection side 20 of the second circuit board 12.

[0089] As can be seen from Figure 6 As can be seen from Figure 6 , each of the spring arms 34 projects outwardly and includes an arcuate free end. This configuration facilitates insertion of the spring arms 34 into corresponding holes at the connection side 20 of the second circuit board 12. It should be noted that the spring arms 34 may also have other configurations. Specifically, the spring arms 34 may project inwardly.

[0090] In addition, in order to provide sufficient spring force to the spring arms 34, the shielding wall 14 may be made of spring steel.

[0091] It should also be noted that the maximum opening size of the cavity formed by the space between adjacent spring arms 34 is at least 1 mm, preferably at least 2 mm, and most preferably at least 5 mm.

[0092] Now turning to Figure 7 and Figure 8 Figure 8 , a fourth embodiment of the control unit is described.

[0093] The control unit of the fourth embodiment has a shielding wall 14, which includes a first wall segment 14a and a second wall segment 14b.

[0094] The first wall segment 14a is connected to the first circuit board 10, while the second wall segment 14b is connected to the second circuit board 12.

[0095] Specifically, as described in the case of the first embodiment regarding the material bonding of the shielding wall 14 to the first circuit board 10, the first wall segment 14a is connected to the first circuit board 10 by material bonding.

[0096] The second wall segment 14b is connected to the second circuit board 12 by material bonding in a manner similar to that of connecting the first wall segment 14a to the first circuit board 10.

[0097] It should be understood that at least one of the first wall segment 14a and the second wall segment 14b may be connected to the corresponding circuit boards 10, 12 by force fit as described above regarding the first embodiment to the third embodiment. It should be understood that the wall segments 14a, 14b and / or the connection sides 18, 20 are then configured in a corresponding manner.

[0098] As can be further seen from Figure 7 As can be further seen from Figure 7 , in the assembled state of the control unit, the first wall segment 14a is completely circumferentially surrounded by the second wall segment 14b. However, the first wall segment 14a may also be only segmentally (in a segmented manner) surrounded by the second wall segment 14b.

[0099] In addition, as Figure 8 As shown in the cross-sectional view of Figure 8 , in the assembled state of the control unit, the first wall segment 14a and the second wall segment 14b do not contact, especially do not have electrical contact.

[0100] Furthermore, the first wall segment 14a connected to the first circuit board 10 is not in contact with the second circuit board 12. In a similar manner, the second wall segment 14b connected to the second circuit board 12 is not in contact with the first circuit board 10. This can be achieved, for example, by arranging a spacer (not shown) between the first circuit board 10 and the second circuit board 12.
