Abstract

An electrically driven vehicle, especially a passenger motor vehicle with an electric power source taken along in the vehicle which is arranged in the area of the vehicle floor and is connected therewith by way of mounting supports, whereby the latter are provided with means that effect a detachment of the electric power source, especially of a storage battery, from the vehicle in case of an impact of the vehicle beginning with a predetermined impact strength.

Claims

1. An electrically driven vehicle with a vehicle floor comprising electric power source means taken along in the vehicle, said electric power source means being arranged within the area of the vehicle floor and depending therefrom by way of mounting support means, characterized in that the mounting support means include a further means which, in case of a vehicle impact of predetermined strength, disconnects the support means and the power source means to effect a detachment of the electric power source means from the vehicle.

2. A vehicle according to claim 1, characterized in that the electric power source means is a storage battery.

3. A vehicle according to claim 1, characterized in that the vehicle is an electrically driven passenger motor vehicle.

4. A vehicle according to claim 1, characterized in that the further means includes an intentional rupturing element.

5. A vehicle according to claim 4, characterized in that the mounting support means includes longitudinally spaced angle rail means arranged at the vehicle floor and extending transversely to the driving direction, and a carrying means carrying the electric power source means and having flange means supported by said angle rail means, and wherein the angle rail means and the associated flange means which is disposed forwardly in the driving direction comprise said rupturing element.

6. A vehicle according to claim 5, characterized in that the intentional rupturing element is realized by means of a weak welded connection between the angle rail means and the vehicle floor.

7. A vehicle according to claim 6, characterized in that the vehicle floor includes a bay extending essentially over the vehicle width in which is arranged the carrying means suspended at the vehicle bottom side by way of the angle rail means, the section of the bay which is disposed forwardly in the driving direction being shaped to extend obliquely downwardly in the forward direction.

8. A vehicle according to claim 7, characterized in that the carrying means includes a trough means, the flange means being formed by angularly bent edge portions of the longitudinal sides of the trough means which project from the trough means.

9. A vehicle according to claim 8, characterized in that the trough means is made of high strength plastic material.

10. A vehicle according to claim 8, characterized in that the trough means is made of reinforced synthetic resinous material.

11. A vehicle according to claim 7, wherein said carrying means comprises a housing means for the electric power source means, characterized in that said flange means are formed on the housing means.

12. A vehicle according to claim 5, characterized in that the intentional rupturing element is placed in one of the flange means.

13. A vehicle according to claim 5, characterized in that the intentional rupturing element is in one of the angle rail means.

14. A vehicle according to claim 5, characterized in that the electric power source means is a storage battery.

15. A vehicle according to claim 14, characterized in that the carrying means includes a trough means, the flange means being formed by angularly bent edge portions of the longitudinal sides of the trough means which project from the trough means.

16. A vehicle according to claim 15, characterized in that the intentional rupturing element is placed in one of the flange means.

17. A vehicle according to claim 15, characterized in that the intentional rupturing element is in one of the angle rail means.

18. A vehicle according to claim 14, wherein said carrying means comprises a housing means for the electric power source means, characterized in that said flange means are formed on the housing means.

19. A vehicle according to claim 18, characterized in that the intentional rupturing element is placed in one of the flange means.

20. A vehicle according to claim 18, characterized in that the intentional rupturing element is in one of the angle rail means.

21. A vehicle according to claim 4, characterized in that the intentional rupturing element is realized by means of a weak welded connection.

22. A vehicle according to claim 1, characterized in that the mounting support means include longitudinally spaced angle rail means arranged at the vehicle floor and extending transversely to the driving direction, and a carrying means carrying the electric power source means and having flange means supported by said angle rail means, and wherein a connection of the angle rail means and the associated flange means which is disposed forwardly in the driving direction with the vehicle floor comprises said further means.

23. A vehicle according to claim 22, characterized in that the vehicle floor includes a bay extending essentially over the vehicle width in which is arranged the carrying means suspended at the vehicle bottom side by way of the angle rail means, the section of the bay which is disposed forwardly in the driving direction being shaped to extend obliquely downwardly in the forward direction.
