Abstract

The invention relates to a battery retaining device, comprising a guide device which is designed to receive a vehicle battery; at least one retaining element which is designed to rigidly retain a vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state; and an actuator system with at least one actuator which is designed to bring the at least one retaining element from the first operating state to the second operating state.

First claim

What is claimed is:

1. A battery retaining device, comprising:
a guide device which is configured to receive a vehicle battery;
at least one retaining element which is configured to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state; and
an actuator system with at least one actuator which is configured to bring the at least one retaining element from the first operating state to the second operating state,
wherein the at least one retaining element comprises a rotatable locking bar having a taper in a width direction, wherein the vehicle battery received in the guide device presses perpendicularly to the width direction against the rotatable locking bar in the first operating state and presses along the width direction against the rotatable locking bar in the second operating state, and wherein the actuator system is configured to rotate the rotatable locking bar perpendicularly to the width direction.

2. The battery retaining device according to claim 1 , further comprising:
a control device which is configured to actuate the actuator system for changing the operating system of the at least one retaining element as a function of sensor signals, which indicate in which state of deceleration the battery retaining device is located.

3. A mounting system for mounting a vehicle battery to a vehicle body of a vehicle, comprising:
a battery retaining device according to claim 1 ; and
a vehicle battery which is retained in the battery retaining device.

4. A vehicle comprising:
a vehicle body; and
a mounting system including a battery retaining device and a vehicle battery retained in the battery retaining device,
wherein the battery retaining device includes a guide device which is configured to receive a vehicle battery, at least one retaining element which is configured to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state, and an actuator system with at least one actuator which is configured to bring the at least one retaining element; from the first operating state to the second operating state, and
wherein the battery retaining device is rigidly connected to the vehicle body in a mechanical manner,
wherein the at least one retaining element comprises a rotatable locking bar having a taper in a width direction, wherein the vehicle battery received in the guide device presses perpendicularly to the width direction against the rotatable locking bar in the first operating state and presses along the width direction against the rotatable locking bar in the second operating state, and wherein the actuator system is configured to rotate the rotatable locking bar perpendicularly to the width direction.

5. The vehicle according to claim 4 , further comprising:
a control device which is configured to actuate the actuator system for changing the operating system of the at least one retaining element as a function of sensor signals, which indicate in which state of deceleration the battery retaining device is located.

6. A battery retaining device, comprising:
a guide device which is configured to receive a vehicle battery;
at least one retaining element which is configured to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state; and
an actuator system with at least one actuator which is configured to bring the at least one retaining element from the first operating state to the second operating state,
wherein the at least one retaining element comprises a locking bar which retains a vehicle battery received in the guide device and which has a predetermined breaking point which is mounted at the height of a wedge tip of a wedge rigidly mounted to the guide device, and wherein the actuator system is configured to displace the locking bar perpendicularly to the wedge tip of the wedge.

7. The battery retaining device according to claim 6 , further comprising:
a control device which is configured to actuate the actuator system for changing the operating system of the at least one retaining element as a function of sensor signals, which indicate in which state of deceleration the battery retaining device is located.

8. A mounting system for mounting a vehicle battery to a vehicle body of a vehicle, comprising:
a battery retaining device according to claim 6 ; and
a vehicle battery which is retained in the battery retaining device.

9. A vehicle comprising:
a vehicle body; and
a mounting system including a battery retaining device and a vehicle battery retained in the battery retaining device,
wherein the battery retaining device includes a guide device which is configured to receive a vehicle battery, at least one retaining element which is configured to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a first maximum retaining force value in a first operating state and to rigidly retain the vehicle battery received in the guide device in a mechanical manner up to a second maximum retaining force value in a second operating state, and an actuator system with at least one actuator which is configured to bring the at least one retaining element from the first operating state to the second operating state, and
wherein the battery retaining device is rigidly connected to the vehicle body in a mechanical manner,
wherein the at least one retaining element comprises a locking bar which retains a vehicle battery received in the guide device and which has a predetermined breaking point which is mounted at the height of a wedge tip of a wedge rigidly mounted to the guide device, and wherein the actuator system is configured to displace the locking bar perpendicularly to the wedge tip of the wedge.

10. The vehicle according to claim 9 , further comprising:
a control device which is configured to actuate the actuator system for changing the operating system of the at least one retaining element as a function of sensor signals, which indicate in which state of deceleration the battery retaining device is located.
