Abstract

The invention relates to an arrangement comprising an energy storage module, a module carrier, particularly a vehicle body, and a ball lock bolt for fastening the energy storage module on the module carrier.

First claim

What is claimed is:

1. An arrangement for securing an energy storage module on a module carrier, the arrangement comprising:
an energy storage module, including one or more energy storage cells braced together in series between opposing end plates,
a module carrier, and
a ball lock bolt inserted into a chamber formed within at least one end plate so as to fasten the energy storage module on the module carrier.

2. The arrangement according to claim 1 , wherein a first end of a ball lock bolt is fixedly connected with one of (i) the module carrier, wherein the energy storage module is fitted on a second end of the ball lock bolt and can be latched and unlatched by means of balls at a circumference of the ball lock bolt, and (ii) the energy storage module, wherein the module carrier is fitted on the second end of the ball lock bolt and can be latched and unlatched by means of balls on the circumference of the ball lock bolt.

3. The arrangement according to claim 2 , wherein a clamping sleeve is arranged on the ball lock bolt between the first end and the balls, for the transmission of force between the balls and the one of the energy storage module and the module carrier fixedly connected to the first end.

4. The arrangement according to claim 3 , wherein on a side facing the balls, the clamping sleeve has a funnel-shaped clamping cone configured as a supporting surface for the balls.

5. The arrangement according to claim 3 , wherein the clamping sleeve comprises at least one disk spring and at least one elastic element compensating play in an axial direction.

6. The arrangement according to claim 4 , the clamping sleeve comprises at least one disk spring and at least one elastic element compensating play in an axial direction.

7. An arrangement for fastening an energy storage module on a module carrier, the arrangement comprising:
an energy storage module, including one or more energy storage cells braced together in series between opposing end plates,
a module carrier, and
a clamping device inserted into a chamber formed within at least one end plate so as to fasten the energy storage module on the module carrier, the clamping device comprising: a clamping bolt and a clamping sleeve expanded by the clamping bolt.

8. The arrangement according to claim 7 , wherein a first end of the clamping bolt is screwed into one of (i) the module carrier, wherein the energy storage module can be fitted on a second end of the clamping bolt and can be clamped by means of an expanding of the clamping sleeve, and (ii) the energy storage module, wherein the module carrier can be fitted on the second end of the clamping bolt and can be clamped by means of an expanding of the clamping sleeve.

9. The arrangement according to claim 8 , wherein the clamping sleeve is arranged on the clamping bolt between the first end and a clamping bolt head and is configured to transmit force between the clamping bolt head and the one of the energy storage module and the module carrier fixedly connected to the first end.

10. The arrangement according to claim 8 , wherein the clamping sleeve has a slot in an axial direction.

11. The arrangement according to claim 9 , wherein a side of the clamping sleeve facing the clamping bolt has a funnel-shaped clamping cone, and wherein an outer cone of the clamping bolt head rests flatly on the clamping cone so as to expand the clamping sleeve when the clamping bolt is screwed in.

12. The arrangement according to claim 9 , wherein the clamping sleeve has a slot in an axial direction.

13. The arrangement according to claim 11 , wherein the clamping sleeve has a slot in an axial direction.

14. The arrangement according to claim 7 , wherein the clamping sleeve has a slot in an axial direction.

15. An arrangement for fastening an energy storage module on a module carrier, the arrangement comprising:
an energy storage module, including one or more energy storage cells braced together in series between opposing end plates,
a module carrier, and
a detent device inserted into a chamber formed within at least one end plate so as to fasten the energy storage module on the module carrier, wherein the detent device comprises a mounting device having at least one detent lug and a detent tongue engaging behind the detent lug.

16. The arrangement according to claim 15 , wherein a first end of the mounting device is fixedly connected with one of (i) the module carrier, wherein the energy storage module can be fitted onto a second end of the mounting device and can be latched and unlatched by means of the detent lug and the detent tongue, and (ii) the energy storage module, wherein the module carrier can be fitted onto the second end of the mounting device and can be latched and unlatched by means of the detent lug and the detent tongue.

17. The arrangement according to claim 15 , wherein the detent tongue is designed to be one of elastic and spring-loaded for an independent engaging behind the detent lug.

18. The arrangement according to claim 16 , wherein the detent tongue is designed to be one of elastic and spring-loaded for an independent engaging behind the detent lug.

19. The arrangement according to claim 15 , wherein the mounting device comprises a plurality of parallel detent lugs.

20. The arrangement according to claim 15 , wherein the energy storage module comprises a device for the power supply of a motor vehicle.
