The invention further relates to a so-called platen for a modular device comprising a plurality of individual modules and to a modular device having such a platen.
Background
The module arrangement concerned is a structural unit with a plurality of individual modules, which are combined to form a stack, wherein the stack is fastened together with the end-side pressure plate by at least one encircling tensioning band. The pressure plate homogenizes the tension and also has a protective and fixing function. Preferably, the individual modules are of square design, in particular of plate-like design.
From the closest DE 10 2018 217 253 A1 a method for producing a battery module arrangement is known, which method has the following steps:
-arranging a plurality of accumulator cells into a cell stack, wherein a first and a second pressure plate are arranged at the ends of the cell stack, both pressure plates having pocket-type recesses;
-arranging at least one tensioning band binding the cell stack such that both band ends of the tensioning band are located at pocket-type recesses of the second press plate;
the cell stack is pressed, wherein the belt ends of the tensioning belts are pressed into pocket-type recesses and the pocket-type recesses are filled with plastic or glue for the continuous fixing of the belt ends.
Disclosure of Invention
The present invention should be improved over the prior art described above.
This is achieved by the method according to the invention as claimed in claim 1. The invention also covers a press plate according to the invention as set forth in the accompanying claims. The invention also covers a module arrangement, in particular a battery module arrangement, as claimed in another parallel claim. Additional features of the invention result from the dependent claims, the following description of the invention (where this also explicitly includes features described as "for example", "preferred", "in particular" etc.), and the accompanying drawings, which apply similarly to all inventive objects.
The method according to the invention for manufacturing a modular arrangement comprising a plurality of individual modules comprises at least the following steps:
-arranging the individual modules into a module stack, positioning a first press plate and a second press plate at opposite ends of the module stack, wherein the second press plate has a steering device for tensioning the belt ends of the belt;
-arranging a tensioning belt cinching or wrapping the module stack and the first and second press plates, wherein the belt ends of the tensioning belt are guided through the steering means of the second press plate and are steered/turned towards the opposite lateral direction;
pretensioning the module stack, if necessary, in a pretensioning device (for example as described in DE 10 2016 200 496 A1) or the like;
-tensioning the tensioning strap by applying a pulling force at the strap end;
-fixing, in particular permanently fixing, the belt end of the tensioned tensioning belt at the second pressure plate.
According to the invention, a second pressure plate is used which is equipped with a steering device for tensioning the belt end, as will be explained in more detail below. The belt end of the tensioning belt is guided through the steering device of the second pressure plate and is turned in the opposite transverse direction, in particular transversely to the belt entry direction (see below). Thereby, the belt end can be better grasped for applying the pulling force, so that also very high pulling forces can be applied to the tensioning belt, and a pretensioning device may not be required. Furthermore, in the steering device, in particular at the steering bridge or the like, a friction effect is produced, whereby slipping back of the belt end is prevented or at least reduced and whereby the fixing of the belt end is also simplified.
The tension band is formed of a suitable material and has a suitable width and thickness. Preferably, a constant width and/or thickness is provided. Preferably, the tensioning belt is formed from a fiber-reinforced plastic, for example from a continuous carbon fiber-reinforced or continuous glass fiber-reinforced thermoplastic, in particular from a corresponding semifinished belt. However, the tensioning belt can also be a metal belt, in particular a steel belt. The tensioning belt has two (open) belt ends which are not connected to one another but are fixed individually at the second pressure plate. Depending on the length of the tensioning belt provided, it may be provided that at least one belt end is cut back again before or after the fixing.
The deflection device of the second pressure plate can have at least one passage opening for the belt end (see below), wherein the belt end (of the tensioned tensioning belt) can be fastened to the second pressure plate by pouring the passage opening with a pouring material, in particular a plastic or glue pouring material, and optionally also with a metal melt, for example an aluminum melt. The second pressure plate can also be designed with a belt guide slot or an underside, which can be impregnated with an impregnating material for fixing the belt ends. Preferably, the potting material is also injected. The belt ends may also be fixed together with the second press plate or at the second press plate by bonding or welding, that is to say the belt ends are bonded or welded to the second press plate. The belt ends may also be secured at the second platen with clip elements. The clip element enables a simple release of the fixation. The fastening measures may also be combined with one another.
A (second) pressure plate according to the invention for a modular arrangement comprising a plurality of individual modules, wherein the pressure plate is arranged at the end of a modular stack formed by the individual modules and is connected to the modular stack by means of a tensioning belt, has a steering device for the belt end of the tensioning belt, which is designed such that the belt end of the tensioning belt can be steered in opposite lateral directions, that is to say by means of the steering device.
The deflecting device of the pressure plate can have a passage opening for the two belt ends of the tensioning belt, which passage opening is preferably embodied as an elongated hole extending obliquely, in particular obliquely, with respect to the belt entry direction. It is likewise possible to provide each belt end with a separate passage opening, in particular designed as a slot.
The deflection device of the pressure plate can have a belt guide groove for the belt end, in particular a lower belt guide groove or a belt guide cutout, which is preferably of arcuate design, as will be explained in more detail below.
The pressure plate is preferably produced integrally with the deflection device from plastic, in particular fiber-reinforced plastic (for example carbon-fiber-reinforced or glass-fiber-reinforced thermoplastic) or from metal (for example aluminum alloy). Preferably, the pressure plate is a one-piece plastic injection molded part or a metal die cast part. The pressure plate can be designed as a solid structure or can also be designed as a shell structure.
The module device according to the invention comprises: a module stack formed from a plurality of individual modules, the first and second platens being positioned at opposite ends of the module stack; and at least one tensioning strap cinching the module stack (including the first and second platens). The second pressure plate is designed with a steering device, as described above. It is furthermore preferably provided that the belt ends of the tensioning belt are turned in the opposite transverse direction and are fixed to the second pressure plate, as described above. The modular device according to the invention is manufactured in particular by the method according to the invention, as described above.
Preferably, the individual modules are electrical battery modules or the like forming a battery module arrangement.

Detailed Description
The modular arrangement 100 shown in fig. 1 has a plurality of individual modules 110 which are combined to form a module stack. The individual modules 110 in particular form battery modules of a battery module arrangement. A first (lower) platen 120 and a second (upper) platen 130 are arranged at the ends of the module stack. Furthermore, a tensioning strap 140 is provided which tightens the module stack together with the pressure plates 120, 130, which tightens the module stack while maintaining the tightening force. The one-piece and in particular also one-piece tensioning band 140 can be fastened, for example welded, approximately centrally to the first pressure plate 120. The two belt ends of the tension belt 140 are fixed at the second pressing plate 130 as described below.
In the following, it is assumed in a non-limiting manner that the modular arrangement 100 shown in fig. 1 has only one first (lower) platen 120, only one second (upper) platen 130 and only one tensioning belt 140. The modular apparatus 100 may also have a plurality of first (lower) platens 120, a plurality of second (upper) platens 130, and/or a plurality of tension bands 140. The following description applies equally to this.
Fig. 2 shows a second (upper) platen 130. The pressure plate 130 is designed as a rectangular plate and is preferably manufactured as solid (that is to say made of solid material) and integral (that is to say manufactured in one piece). The pressure plate 130 may also be a ribbed shell. As shown, the upper side 131 of the platen 130 may be designed with a belt guide slot for tensioning the upper side of the belt 140. The pressure plate 130 is designed with a so-called steering device 132 for tensioning the two belt ends of the belt 140. Such an integrated steering device 132 enables the direction of the belt end of the tensioning belt 140 to be changed in a defined manner and can therefore also be referred to as a steering device or belt steering device.
The deflection device 132 of the pressure plate 130 has a passage opening 133 for the belt end, preferably the center, of the tensioning belt 140 or in the middle of the plate, which is designed as a slot. (likewise, two passage openings can also be provided for one of the belt ends) the slot 133 extends obliquely with respect to the belt entry direction E. The angle of inclination W is here about 40 ° to 50 °, in particular about 45 °, but may also be greater or smaller. The two longitudinal inner edges 134 of the slot 133 are rounded. The pressure plate 130 is designed on its underside with an underside belt guide slot 135 which is guided out of the passage opening 133 laterally or laterally.
Fig. 3 shows the second (upper) platen 130 when tensioning the tensioning band 140 without showing the individual modules 110. The belt ends 141, 142 of the tensioning belt 140 are guided through the opening 133 and are turned in opposite lateral directions, i.e. transversely to the belt entry direction E, and are guided laterally outwards. The rounded longitudinal inner edge 134 of the slot 133 then serves as a steering bridge (first turn) for the strap ends 141, 142. The tension band 140 is tensioned by applying opposing tension or tightening forces S to the band ends 141, 142. The lower belt guide groove 135 is designed to be wider than the tensioning belt 140 or its belt ends 141, 142, so that the direction of the pulling or tensioning force S can be slightly changed. The assembly of the module stack can be carried out with the aid of a pretensioning device (see above) or, if appropriate, also with the aid of an injection molding machine (see below), which can also have a device suitable for applying a tensile or tensioning force S.
Fig. 4 shows an embodiment of securing the belt ends 141, 142 by pouring or filling through the opening 133 and/or the belt guide groove 135 on the underside with pouring material K. The injection can be carried out in an injection molding machine, which can also be used to pretension the module stack if necessary. The strap ends 141, 142 may then be shortened or cut away. Furthermore, by a suitable design of the through opening 133, a wedging effect which facilitates self-locking can be achieved, as shown in the detailed cross-section.
Fig. 5 shows a further embodiment for fastening the belt ends 141, 142 in that the belt ends are turned over the rounded lateral turning edges 137 (second turn) at the pressure plate 130 onto the upper side 131 and are glued or welded to the pressure plate 130. The turndown edge 137 likewise serves as a steering bridge (second turn) for the belt ends 141, 142. In this case, the adhesive or welding 138 is performed in a punctiform manner. When the materials are combined appropriately, the welding can be carried out by means of hot embossing. The joint overlap length can be made relatively short due to the strong friction caused by the double turning at the longitudinal inner edge 134 of the slot 133 and at the lateral turning edge 137.
Fig. 6 shows a further embodiment for fastening the belt ends 141, 142 by turning the belt ends over the rounded lateral turning edges 137 onto the upper side 131 of the pressure plate 130 and fastening them by means of clip elements 139 or the like. The fastening arrangements according to fig. 4 to 6 can also be combined with one another.
Fig. 7 shows a further embodiment of the upper (second) pressure plate 130 in a detail view, wherein the diverted belt ends 141, 142 of the tensioning belt 140 are not guided on the underside of the pressure plate 130, but laterally outwards through the pressure plate 130. For this purpose, the pressure plate 130 is designed with two belt guide cutouts 136 which lead out through the openings 133. Preferably, the strip guide cutout 136 is convexly arched relative to the upper side 131 or concavely arched relative to the lower side. By means of this arching, on the one hand the belt ends 141, 142 harden themselves, so that the pressure plate 130 can possibly be constructed thinner and lighter. On the other hand, the surface pressure between the respective belt ends 141, 142 and the platen 130 is equalized. (this arching principle can also be applied to the belt guide grooves 135 at the lower side of the pressing plate 130 shown in fig. 2 to 6.)
Furthermore, the belt guide slit 136 is preferably designed to be wider than the tensioning belt 140 or its belt ends 141, 142, so that the tension direction can be changed when the tension S (see fig. 3) is pulled or applied. To secure the strap ends 141, 142, the infusion material K may be used to infuse through the opening 133 and/or the strap guide slit 136. The fixation may also be achieved by means of adhesive or welding or by means of clip elements (similar to the fixation according to fig. 5 or 6).
The pressure plate 130 shown in fig. 2 to 7 can also be used as the lower pressure plate 120 in the modular device 100 shown in fig. 1, wherein the steering device 132 remains unused. Furthermore, the tension band 140 may also have a varying width, unlike the case shown in the figures.
