Description
The invention relates to a battery cell, particularly for submarines, comprising a housing made of insulating material which holds the acid and plates and which is provided on its underside with at least one first rail having a hook-like cross-section and connectable to a stationary second rail fastened to a base of a submarine by mutually hooking in that in each case one leg of the one rail is brought into positive locking engagement in a groove formed by the other rail.
To fasten battery cells to submarines it is known to attach a steel rail both to the underside of each cell or each housing and also to the submarine body, whereby the rails have a hook-like cross-section and interlock in the hook areas. The steel rails on the housing are thereby screwed to nut-shaped fastening elements made of steel and anchored to the bottom of the housing. Furthermore, it is known to attach by glueing hook-like structural members made of steel to the underside of the housing bottom and in addition to surround the fastening section of the hook-like structural members adjacent the housing bottom with a plastic laminate. The hook-like structural members again engage in a hook-like steel rail fastened to the body of the submarine.
A disadvantage of these fastening configurations is that when shock stresses act on the submarine body notch effects start from the edges of the steel fastening members on the housing resulting in a delamination of the glass fiber-reinforced layers of the battery cells which leads to destruction of the housing and additional disadvantages caused by this. To maintain the insulat-~304778 ing property impaired on account of the damage to the plastic housing caused by the notch effects, additional, relatively thick rubber bags are provided in the housings for the sulfuric acid of the battery cells. The shock effects can also damage the rubber bags, resulting in a time-consuming and expensive exchange of battery cells. A further disadvantage of the double hook con-struction explained above is that it results in a relatively high height which allows the cell to have only a limited acid capacity since the mounting location for the batteries in the submarines is otherwise too tight.
The object of the present invention lies in improving a battery cell of the kind named in the introduction such that with respect to its fastening configuration the bottom of the battery cell is designed in such a way that it does not sustain any damage caused by shock loads, that the use of an additional insulation -rubber bag is superfluous and that the structural height of the means for fastening the battery to the bottom of the cell is reduced.
The solution of the object starts with the battery cell indicated and is characterized in that the first rail is shaped on the housing bottom and forms an integral component of the housing.
In a further development of the subject matter of the present invention the housing can be provided at least in the area of its rail and the bottom portions adjacent thereto with a rein-forcement embedded in the housing and rail material, such as 130477~
2784~-1 rovings of glass and/or carbon fibers which are preferably placed at an angle of 180 about the hook portion of the first rail. In a further embodiment one portion of the bottom surface of the housing can be offset upwardly by the measure of elevation of the second rail so that the second rail essentially occupies the space created by the shoulder between the bottom surface and a support belonging to a base. The inner side of the housing bottom adja-cent the offset bottom surface preferably changes into two hollows.
The aforenamed notch effects in the bottom area of the battery cells are avoided by the solution according to the present invention since the steel or metal anchoring members on the housing are unnecessary. Instead, corresponding hooks are shaped on the bottom area of the cells from the material of the housing bottom, said hooks engaging the hook-like steel rails on the submarine.
Such a hook-like cross-sectional design of the battery housing bottom simultaneously results in a considerably lower structural height of the fastening construction in question, which, with the same structural height of the battery cell, has an enlarging effect on the acid capacity of the cell. Since the housing bottom is also more resistant to destruction, namely on account of the notch effects no longer present, a thick rubber bag as an additional inner protective lining for maintaining the insu-lating property of the battery cell is also superfluous so that 13047~8 possibly a relatively thin and paste-like protective layer is sufficient.
The invention is explained in greater detail here below on the basis of several exemplary embodiments illustrated in the attached drawings.

The leg 4, which is made from the same material as the bottom wall 1304~7B
To fasten battery cells to submarines it is known to attach a steel rail both to the underside of each cell or each housing and also to the submarine body, whereby the rails have a hook-like cross-section and interlock in the hook areas.

The solution of the object starts with the battery cell indicated and is characterized in that the first rail is shaped on the housing bottom and forms an integral component of the housing.

The invention is explained in greater detail here below on the basis of several exemplary embodiments illustrated in the attached drawings.
Figure 1 shows a partially illustrated cross-section through a first exemplary embodiment;
Figures 2 and 3 show a partially illustrated cross-section through a modified first exemplary embodiment;
Figure 4 shows a partially illustrated cross-section through a second exemplary embodiment;
Figure 5 shows a partially illustrated cross-section through a modified second exemplary embodiment.
According to Figure 1 the battery cell housing 1 of usual shape, which contains in known fashion the storage plates and the acid not shown, is illustrated only in part.
A holding fixture 3 in the form of a hook is shaped in the bottom wall 2 of the housing 1 in such a way that the bottom wall projects into the housing interior and that the straight, free leg 4 is shaped on the outer side of the bottom wall such that it runs parallel at a distance to the offset bottom wall area 2a and is in alignment with the non-offset bottom wall area 2b so that a space 5 in the form of a groove is formed between the leg 4 and the bottom wall area 2a in which a counterholding member engages in positive locking manner, as will be explained later.
The leg 4, which is made from the same material as the bottom wall 1304~7B
2, extends in its width in the direction of the width of the hous-ing 1 (Figure 1), whereas its longitudinal direction is identical to the longitudinal direction of the housing 1 and it preferably is also the same length as the housing. The design of the holding fixture 3, i.e. the design of the leg 4 and the space 5, makes it possible among other things to increase the capacity of the housing since in comparison with the previously known fastening rail on the housing the space for the rail foot (flange) is saved since its function is now taken over by the housing bottom 2.
Compared to the non-offset bottom wall area 2b, a hollow 6 extending in the longitudinal direction of the housing 1 results through the offset bottom wall area 2a, said hollow representing an additional increase in the capacity of the housing.
The housing 1, made from plastic and manufactured in a laminate constructional form, is provided at least in the area of the holding fixture 3 and the adjacent bottom portions with a reinforcement embedded in the material of the bottom and the holding fixture. This reinforcement, for example, can be in the form of rovings from glass and/or carbon fibers. In Figure 1, for example, two fibrous layers 7 and 8 are indicated. Whereas fibrous layer 7 for the most part reinforces the bottom wall 2, fibrous layer 8 is positioned such that it is preferably placed in a bend at an angle of 180 so that it extends into the leg 4 which forms with the opposite bottom wall area 2a a hook which can be considered as the first hook rail on account of its longitudinal extension in the longitudinal direction of the housing.
~304778 A second hook rail 9 made of steel is connected to a base 11 of the submarine by means of screw connections 10, whereby an equalizing (compensating) layer 12 is provided between the rail 9 and the base 11. The second rail 9 likewise has a leg 13 and a recess 14, whereby the design of both parts is correspondingly complementary to the first leg 4 and the space 5 bound by said leg. The second leg 13 forms the aforementioned counterholding member and engages in the space 5, whereas the first leg 4 engages in the recess 14.
The clear measure of elevation of the shoulder of the bottom wall area 2a corresponds to the height of the second rail 9, whereby this rail for the most part occupies the space created by the shoulder between the bottom wall area 2a and the equalizing (compensating) support 12 belonging to the base 11.
As Figure 1 shows, the inwardly offset bottom wall area 2a extends from the holding fixture 3 rectilinearly through to the right side wall la of the housing 1. Accordingly, the second hook rail 9 is also designed in such a way that, in relation to its transverse extension, it extends up to the area of the side wall la and fully supports the bottom wall area 2a of the housing 1.
The remaining area 2b of the bottom wall 2 is preferably designed in such a way that it is supported on the layer 12 and thus on the base 11, through which the housing 1 is supported on a very large surface and in a stable manner.
If, as is shown in Figure 1, the second rail 9 is to be optimally, i.e. stably, fastened to the base 11 by means of screw 1304~78 2784~3-1 connections 10 arranged in only one row, and the housing 1 itself is at the same time also to be fastened in a stable manner to the base, then the screw connections can run approximately in the longitudinal center of the rail 9, the rails themselves, however, being disposed eccentrically to the longitudinal center plane 15 of the housing 1.
Figure 2 shows the modified exemplary embodiment in which for the most part the bottom wall 2 of the housing 1 is altered. The raised area 2a of the bottom wall 2 extends to the right not up to the side wall la, but rather sinks again before reaching said wall and forms the bottom wall area 2c which is in alignment with the first area 2b through which a second hollow 16 is formed. Consequently, the second rail 17 on the submarine has a narrower width and through the structural design of the base 11 can likewise be fastened eccentrically to the longitudinal center plane 15 of the housing 1 by means of screw connections.
The housing 1 is supplemented in Figure 2 in that the individual storage plates 18 and the coating 19 made of elec-trically insulating material to improve the insulating property of the battery cell are shown, whereby the latter is secured to the inner surfaces of the housing 1. The coating 19 can consist of a gel coat.
Figure 3 shows a further exemplary embodiment of a housing 1 fastened to the submarine body 22 by means of a single pair of rails 20, 21. In this case also the leg 23 of the first rail 20 on the housing is integrated in the bottom wall 2 to form 27848-l a hook as explained above, whereas the rail design on the sub-marine is known. The difference to the examples according to Figures 1 and 2 lies in the fact that the bottom wall 2 is not offset upwardly, rather is level without the advantage of the increase in the capacity of the housing being lost. Furthermore, two rows of screw connections 10 are provided in order to fasten the second rail 21 on the submarine side to the base 11.
In addition, the housing 1 is provided on the underside of its bottom wall 2 with longitudinally extending projections 24 which form the outer drip edges so that moisture precipitated and running down the side walls of the housing can drip off from the projections.
Figures 4 and 5 show a second exemplary embodiment. The main change compared to the exemplary embodiments according to Figures 1, 2 and 3 lies in the fact that in each case two first rails 25 and 26 are provided on the housing l and two second rails 27 and 28 are provided on the base 11 of the submarine 22, whereby the thus formed pairs of rails are spaced apart from one another.
Although the bottom wall 2 in Figure 4 is advantageously level, which is also the case in the exemplary embodiment according to Figure 5, the exemplary embodiment according to Figure 5 can alternatively also be designed in such a way that a hollow forms in the longitudinal center area of the bottom wall 2 since the two pairs of rails 25, 27; 26, 28 lie farther apart from one another and preferably support the housing 1 on its outer areas.
1304~78 A further embodiment can be designed in such a way that, as shown for example in Figure 2, at ]east one elastomeric damper strip 29, extending transversely over the upwardly offset bottom area 2a of the housing 1, is provided. Its upper edge 29a abuts below the storage plates 18 of the battery cell and thus supports the plates 18, whereas its lower edge 29b is supported both on the offset bottom area 2a and on the hollow areas 2b and 2c of the housing 1. In addition, the or each damper strip 29 is provided with a plurality of openings 30, which can consist for example of through holes, in the section extending above the offset bottom area 2a. On account of the openings 30, the compressed travel of the relevant section is essentially the same as for the remaining sections of the damper strip which do not have any openings but instead have a greater height. This protects the storage plates 18 from varying downward movement during corresponding shock loads or similar loads of the battery cell and thus avoids the danger of the plates 18 losing contact with their pole connections.
Although an innercoating 18 is shown in the exemplary embodiment according to Figure 2, such a coating can also be present in all other exemplary embodiments. The same also applies for the drip edges 24.
Compared to the non-offset bottom wall area 2b, a hollow 6 extending in the longitudinal direction of the housing 1 results through the offset bottom wall area 2a, said hollow representing an additional increase in the capacity of the housing.
The housing 1, made from plastic and manufactured in a laminate constructional form, is provided at least in the area of the holding fixture 3 and the adjacent bottom portions with a reinforcement embedded in the material of the bottom and the holding fixture. This reinforcement, for example, can be in the form of rovings from glass and/or carbon fibers. In Figure 1, for example, two fibrous layers 7 and 8 are indicated. Whereas fibrous layer 7 for the most part reinforces the bottom wall 2, fibrous layer 8 is positioned such that it is preferably placed in a bend at an angle of 180 so that it extends into the leg 4 which forms with the opposite bottom wall area 2a a hook which can be considered as the first hook rail on account of its longitudinal extension in the longitudinal direction of the housing.
~304778 A second hook rail 9 made of steel is connected to a base 11 of the submarine by means of screw connections 10, whereby an equalizing (compensating) layer 12 is provided between the rail 9 and the base 11. The second rail 9 likewise has a leg 13 and a recess 14, whereby the design of both parts is correspondingly complementary to the first leg 4 and the space 5 bound by said leg. The second leg 13 forms the aforementioned counterholding member and engages in the space 5, whereas the first leg 4 engages in the recess 14.
The clear measure of elevation of the shoulder of the bottom wall area 2a corresponds to the height of the second rail 9, whereby this rail for the most part occupies the space created by the shoulder between the bottom wall area 2a and the equalizing (compensating) support 12 belonging to the base 11.
As Figure 1 shows, the inwardly offset bottom wall area 2a extends from the holding fixture 3 rectilinearly through to the right side wall la of the housing 1. Accordingly, the second hook rail 9 is also designed in such a way that, in relation to its transverse extension, it extends up to the area of the side wall la and fully supports the bottom wall area 2a of the housing 1.
The remaining area 2b of the bottom wall 2 is preferably designed in such a way that it is supported on the layer 12 and thus on the base 11, through which the housing 1 is supported on a very large surface and in a stable manner.
If, as is shown in Figure 1, the second rail 9 is to be optimally, i.e. stably, fastened to the base 11 by means of screw 1304~78 2784~3-1 connections 10 arranged in only one row, and the housing 1 itself is at the same time also to be fastened in a stable manner to the base, then the screw connections can run approximately in the longitudinal center of the rail 9, the rails themselves, however, being disposed eccentrically to the longitudinal center plane 15 of the housing 1.
Figure 2 shows the modified exemplary embodiment in which for the most part the bottom wall 2 of the housing 1 is altered. The raised area 2a of the bottom wall 2 extends to the right not up to the side wall la, but rather sinks again before reaching said wall and forms the bottom wall area 2c which is in alignment with the first area 2b through which a second hollow 16 is formed. Consequently, the second rail 17 on the submarine has a narrower width and through the structural design of the base 11 can likewise be fastened eccentrically to the longitudinal center plane 15 of the housing 1 by means of screw connections.
The housing 1 is supplemented in Figure 2 in that the individual storage plates 18 and the coating 19 made of elec-trically insulating material to improve the insulating property of the battery cell are shown, whereby the latter is secured to the inner surfaces of the housing 1. The coating 19 can consist of a gel coat.
Figure 3 shows a further exemplary embodiment of a housing 1 fastened to the submarine body 22 by means of a single pair of rails 20, 21. In this case also the leg 23 of the first rail 20 on the housing is integrated in the bottom wall 2 to form 27848-l a hook as explained above, whereas the rail design on the sub-marine is known. The difference to the examples according to Figures 1 and 2 lies in the fact that the bottom wall 2 is not offset upwardly, rather is level without the advantage of the increase in the capacity of the housing being lost. Furthermore, two rows of screw connections 10 are provided in order to fasten the second rail 21 on the submarine side to the base 11.
In addition, the housing 1 is provided on the underside of its bottom wall 2 with longitudinally extending projections 24 which form the outer drip edges so that moisture precipitated and running down the side walls of the housing can drip off from the projections.
Figures 4 and 5 show a second exemplary embodiment. The main change compared to the exemplary embodiments according to Figures 1, 2 and 3 lies in the fact that in each case two first rails 25 and 26 are provided on the housing l and two second rails 27 and 28 are provided on the base 11 of the submarine 22, whereby the thus formed pairs of rails are spaced apart from one another.
Although the bottom wall 2 in Figure 4 is advantageously level, which is also the case in the exemplary embodiment according to Figure 5, the exemplary embodiment according to Figure 5 can alternatively also be designed in such a way that a hollow forms in the longitudinal center area of the bottom wall 2 since the two pairs of rails 25, 27; 26, 28 lie farther apart from one another and preferably support the housing 1 on its outer areas.
1304~78 A further embodiment can be designed in such a way that, as shown for example in Figure 2, at ]east one elastomeric damper strip 29, extending transversely over the upwardly offset bottom area 2a of the housing 1, is provided. Its upper edge 29a abuts below the storage plates 18 of the battery cell and thus supports the plates 18, whereas its lower edge 29b is supported both on the offset bottom area 2a and on the hollow areas 2b and 2c of the housing 1. In addition, the or each damper strip 29 is provided with a plurality of openings 30, which can consist for example of through holes, in the section extending above the offset bottom area 2a. On account of the openings 30, the compressed travel of the relevant section is essentially the same as for the remaining sections of the damper strip which do not have any openings but instead have a greater height. This protects the storage plates 18 from varying downward movement during corresponding shock loads or similar loads of the battery cell and thus avoids the danger of the plates 18 losing contact with their pole connections.
Although an innercoating 18 is shown in the exemplary embodiment according to Figure 2, such a coating can also be present in all other exemplary embodiments. The same also applies for the drip edges 24.
