Disclosure of Invention
It is therefore an object of the present invention to provide a simple production of the drive device.
According to the invention, this object is achieved by a drive device according to the features specified in claim 1 or 2.
In a drive device, in particular a compact drive device, having a terminal box, an important feature of the invention is that the terminal box has a lower part and a cover connected to the lower part,
wherein power modules, in particular heat-generating power modules, are connected to the cooling plate,
wherein the cooling plate is connected with the holding piece,
the holding element is arranged pressed by at least one spring element supported on the lower element against the cover element, in particular against the inner side of the cover element.
The advantage here is that the power module, together with the cooling plate, can be designed to be preassembled. The cover is thus removable and the power module is nevertheless held by the holder, to which the cooling plate is also connected. In this way, particularly after removal of the cover, simple production, particularly wiring within the junction box, can be carried out. By preassembling, the power module is also held by a holder fixed at the lower part. Thus ensuring a strong structure. Furthermore, the holding part encloses the circuit board stack connected to the power module in a form-fitting manner. In this way, the electronic components mounted on the circuit board stack are also arranged in a protected manner.
In an advantageous embodiment, the power module is mounted on a first circuit board of the circuit board stack,
the circuit board stack has at least one second circuit board, which is parallel to the first circuit board. The advantage here is that simple production is possible.
In an advantageous embodiment, the first printed circuit board and the second printed circuit board are connected at least by means of pins which pass through the printed circuit boards, in particular and are soldered to the printed circuit boards. The advantage here is that simple production is possible.
In an advantageous embodiment, the cover part has cooling ribs/cooling fins and/or cooling fingers on its surface, in particular on its outer surface. The advantage here is that an improved heat dissipation can be achieved.
In an advantageous embodiment, the holder has a cutout, wherein the power module passes through the cutout, in particular towards the cooling plate. The advantage here is that an improved heat dissipation can be achieved. Since the cooling plate can be made of a thermally conductive material as a holder and thus a direct introduction of the heat generated by the power module, i.e. not indirectly via the holder, can be achieved. The holder can thus be made of a material which has a higher load-bearing capacity than the cooling plate.
In an advantageous embodiment, the first printed circuit board is arranged on a side of the holder facing away from the cooling plate. The advantage here is that the holder is arranged in the middle and therefore the power module is spaced apart from the holder in the cutout. Therefore, expansion due to heat can be absorbed.
In an advantageous embodiment, the cooling plate covers, covers and/or closes the recess. The advantage here is that it extends further in a transverse direction transverse to the stacking direction of the circuit board stack than in a direction parallel to the stacking direction.
In an advantageous embodiment, the spring element is arranged between the holding element and the lower element. The spring element can be supported on the lower part and the holding element can be acted upon by the spring element with a spring force generated by the spring element toward the cover element, i.e. away from the lower part. That is, the spring element is arranged in the terminal box with a pretension between the holding element and the lower element.
In an advantageous embodiment, the movement of the holder is guided by means of a guide. The advantage here is that a robust operating mode can be achieved.
In an advantageous embodiment, the movement of the holding element is limited by means of a limiting element. The advantage here is that the preassembled unit can be held together by means of the retaining mechanism, since the retaining mechanism is retained on the lower part by the stop element, i.e. in particular cannot be removed from the lower part to a greater extent than is predetermined by the stop element.
In an advantageous embodiment, the sleeve serves as a guide. The advantage here is that the spring element can be moved back and forth along the sleeve.
In an advantageous embodiment, a screw with a screw head that is screwed into a threaded bore of the lower part or a screw that is inserted or screwed into a bore of the lower part together with a nut that is screwed onto the threaded region of the screw serves as a stop. The advantage here is that simple and cost-effective production can be achieved. In particular, very inexpensive components can be used.
In an advantageous embodiment, a spring element, in particular a spring element designed as an annular spring, is fitted onto the or a sleeve,
wherein the sleeve passes through the other notch of the holding piece,
in particular, the sleeve rests against a stop, in particular a washer, a nut or a screw head. The advantage here is that the spring element is guided and therefore a device that can be produced in a simple manner can be used, in which a reliable mode of operation can be implemented.
In an advantageous embodiment, one or the bolts pass through the sleeve, in particular and therefore also through the holder,
the bolt is inserted or screwed into the lower part and has or is connected to a stop element on the side of the holding element facing away from the lower part. The bolt has the advantage that it supports a stop element, which limits the freedom of movement of the holding element, in particular the play. Thus, the retaining mechanism can reciprocate along the sleeve, but the movement is limited by the limit stop. The lower part connected to the circuit board stack is therefore constructed to be preassembled.
In an advantageous embodiment, the holder has a preferably planar base region,
wherein the holder has a cutout through which the power module passes, in particular toward the cooling plate,
wherein the arm region of the holding element adjoins the base region,
wherein the arm areas are all spaced apart from each other, in particular in a circumferential direction with reference to a normal direction of a plane receiving one circuit board of the stack of circuit boards,
in particular, each arm region has a respective recess through which the respective sleeve passes. The advantage here is that the arm region laterally delimits the circuit board stack and therefore the circuit board stack is held in a form-fitting manner. Furthermore, the curved embodiment of the arm region makes it possible to provide a large distance between the cover element and the lower part, in particular a distance greater than the extent of the contact region of the spring element with the lower part to the contact region of the cooling plate on the inside of the cover element.
In an advantageous embodiment, each arm region has at least two bending points which are in particular opposite one another,
in particular, the bending angle of each bending point has a value of between 70 ° and 110 °, in particular 90 °. The advantage here is that a large distance between the cover and the lower part can be bridged.
In an advantageous embodiment, the distance between the region of the spring element contacting the lower element and the region of the cooling plate contacting the cover element is:
larger than the extension of the circuit board stack together with the power module and the cooling plate,
or greater than the sum of the extension of the spring element and the extension of the circuit board stack together with the power module and the cooling plate,
wherein the extension is measured in a direction normal to a plane receiving one of the circuit boards of the stack of circuit boards. The advantage here is that sufficient free space can be provided for wires, cables, etc., and that fitting space for handling screws, etc., can be provided.
In an advantageous embodiment, the distance between the holes of the lower part receiving the bolts and the contact areas of the cooling plate and the cover is greater than the extension of the circuit board stack together with the power module and the cooling plate,
wherein the extension is measured in a direction normal to a plane receiving one of the circuit boards of the stack of circuit boards. The advantage here is that a larger distance is provided for establishing the electrical connection to the line and thus simpler production is possible.
In an advantageous embodiment, a plug connector is mounted on a third circuit board of the circuit board stack,
the plug-in connection can be plug-in connected with a mating plug-in connection, the stator winding conductor of the motor of the drive device is connected, in particular conductively connected, with the contact of the mating plug-in connection,
and/or bus lines and/or supply lines which are guided through the cable screw sleeve connection are connected, in particular conductively connected, to the contacts of the mating plug connector. The advantage here is that simple contacting can be achieved by means of a plug connection to the mating plug connector.
In an advantageous embodiment, the cooling plate is made of metal, in particular aluminum,
wherein the holding element is made of metal, in particular steel,
wherein the cover is made of metal, in particular aluminum. The advantage here is that a high thermal conductivity enables an effective dissipation of the heat flow of the power module and the holder transmits a high contact pressure. Since the power module passes through the notch of the holder and is connected with the aluminum cooling plate, the power module is spaced apart from the holder. The holder can therefore be made of another material, so that different thermal expansions caused by heat can be absorbed at intervals.
Further advantages are given by the dependent claims. The invention is not limited to the combination of features of the claims. Other possible combinations of the features of the claims and/or of the individual claims and/or of the features of the description and/or of the drawings can be derived by the person skilled in the art, in particular from the objects set forth and/or by comparison with the prior art.

Detailed Description
As shown in the figures, the drive device has a motor, in particular with a reduction gear, wherein the terminal box of the motor has a lower part 1 and a cover 2 mounted on the lower part to form the terminal box.
The cover 2 has cooling ribs, in particular on its outer side facing away from the electric machine.
A circuit board stack 22 is arranged in the terminal block.
The first circuit board 61 is equipped with a power module 65 having controllable semiconductor switches, in particular MOSFETs or IGBTs. The semiconductor switches are preferably arranged in three half-bridges which are connected in parallel with one another, so that these half-bridges form an inverter from which the electric machine can be fed and thus operated with rotational speed regulation.
The second circuit board 62 of the circuit board stack 22 is equipped with signal electronics which generate control signals, in particular pulse-width modulated, for the controllable semiconductor switches of the first circuit board 61.
The third circuit board 63 of the circuit board stack 22 is fitted with a plug connector.
The first, second and third printed circuit boards 61, 62, 63 are connected by means of pins which pass through these printed circuit boards 61, 62, 63, in particular are soldered to the printed circuit boards. The circuit board stack 22 thus formed is pressed with its power module 65 onto the cooling plate 20.
The heat flow generated by the power module 65 is thus diffused in the cooling plate 20 and discharged to the surroundings by pressing the cooling plate 20 onto the cover 2, in particular onto the inner side of the cover 2.
The cover 2 has cooling ribs on its outer side, so that heat is discharged to the surroundings via the thus enlarged surface.
The pressing of the circuit board stack 22 is effected by a spring element 51 which is fitted onto the sleeve 60 and which is supported on the one hand on the lower part 1 and on the other hand on the holding element 21, against which the cooling plate 20 bears, so that the holding element 21, to which a force is applied by the spring element 51, presses the cooling plate 20 onto the cover element 2, in particular onto the inner side of the cover element 2.
Preferably, a thermally conductive paste can also be arranged between the cooling plate 20 and the cover member 2.
The holder 21 is thus arranged on the side of the cooling plate 20 facing away from the cover 2.
The first end region of the screw 50, which projects through the corresponding sleeve 60, is at least partially inserted into the bore of the lower part 1 or is designed as a threaded region and is screwed into a threaded bore of the lower part 1. The other end region of the bolt 50 has a threaded region, onto which a nut 52 is screwed, against which an orifice plate 53 bearing against a sleeve 60 bears. Thus, by screwing the nut 52 onto the threaded region of the bolt 50, the sleeve 60 is fixed on the lower part 1 and the working region of the spring element 51, which is fitted onto the sleeve 60, is defined.
The spring element 51 thus presses the holding element 21 in the direction of the perforated plate 53, in particular the washer. However, the holder 21 is thus pressed in the direction towards the cover 2 and thus the cooling plate 20 is pressed onto the inside of the cover 2.
As shown in fig. 7, the cooling plate 20 is connected to the holder 21 by means of first screws 71. The cooling plate 20 is connected with the power module 65 of the circuit board stack 22 by means of second screws 72.
The holding part 21 is preferably designed as a punch-out part.
The holder 21 has a cutout, through which the power module 65 passes, in order to be able to be connected in particular to the cooling plate 20 placed on the holder 21.
The first screw 71 is screwed with its threaded region into the holding part 21, in particular into a bore machined therein. The heads of the respective screws 71 press the cooling plate 20 onto the holder 21.
The second screw 72 is screwed with its threaded region into the power module 65, in particular into a hole machined therein. The heads of the respective screws 72 press the cooling plate 20 onto the power module 65.
The holder 21 has a preferably flat base region with a cutout, through which the power module 65 projects toward the cooling plate.
Connected to the base region are arm regions which are all spaced apart from one another and each have a recess through which the respective sleeve 60 passes, wherein the respective screw 50 passes through the respective sleeve 60.
The circuit board stack 22 together with the power module 65 is therefore arranged in a protected manner inside the terminal box of the drive device, so that the cover 2 and the lower part 1 enclose the circuit board stack in such a way that a housing is formed. A mating plug connection can be connected to the plug connection 64 mounted on the third circuit board 63, so that the lines of the stator winding from the motor of the drive device can be electrically connected and/or the lines from the ac voltage source can be electrically connected.
The circuit board stack 22 preferably functions as a current transformer so that the rotational speed or torque of the motor is adjustable.
Each arm region has two bending points, each of which has a 90 ° bend, in particular wherein the first bending point is designed opposite the second bending point. Thus, spring elements 51 can be used which extend in the direction of the center axis of the bolt 50 or the sleeve 60 less than the circuit board stack.
It is in any case important that the spacing between the holes of the lower part 1 receiving the bolts 50 and the contact areas of the cooling plate 20 and the cover 2 is greater than the extension of the circuit board stack 22 together with the power module 65 and the cooling plate 20.
Preferably, the central axis is oriented parallel to the normal direction of the plane containing one of the circuit boards 61, 62, 63 oriented parallel to each other.
The data bus lines are routed to the plug connectors 64 of the circuit board stack 22 via cable leadthroughs arranged in the wall of the lower part 1.
As shown in fig. 4, the holding part 21 encompasses the circuit board stack 22 with its arm regions in a spider-like and/or claw-like manner. The circuit boards 61, 62, 63 are therefore preferably received in the holding part 21 in a form-fitting manner, since at least one arm region is arranged on each of the sides of the circuit board stack 22 that do not face the lower part 1.
In other embodiments according to the invention, instead of a nut with a washer, a limitation implemented in other ways is implemented with regard to the freedom of movement of the holder. For example, the sleeve 60 is eliminated and the bolt has a widening instead of the screwed nut 52 and the sleeved perforated plate 53. Instead of the screw 50, a screw with a screw head can therefore also be screwed into the threaded hole of the lower part 1.
Therefore, a sleeve for guiding the spring element 51 is also not required, since the screw or bolt 50 can be guided. For this purpose, a smooth surface is preferably formed on the screw or bolt 50.
