Abstract

Industrial truck with a drive part which comprises an electrical travel drive, a load part which comprises a load carrying means and which may be lifted relative to the drive part, a battery receiving space and an energy module which may be handled manually, which may be inserted into the battery receiving space and which comprises a battery for supplying power to the travel drive, the energy module having a defined installed position in the state inserted into the battery receiving space, the battery receiving space enclosing the energy module in the inserted state so that the energy module is not displaceable in the defined installed position but may only be removed from the battery receiving space after being tilted, during the tilting process an upper end of the energy module being moved by a predetermined angle about a horizontal pivot axis.

Claims

1. Industrial truck with a drive part (10) which comprises an electrical travel drive, a load part (12) which comprises a load carrying means and which may be lifted relative to the drive part (10), a battery receiving space and an energy module (24) which may be handled manually, which may be inserted into the battery receiving space and which comprises a battery (64) for supplying power to the travel drive, the energy module (24) having a defined installed position in the state inserted into the battery receiving space, characterised in that the battery receiving space encloses the energy module (24) in the inserted state so that the energy module (24) is not displaceable in the defined installed position but may only be removed from the battery receiving space after being tilted, during the tilting process an upper end of the energy module (24) being moved by a predetermined angle about a horizontal pivot axis.

2. Industrial truck according to claim 1, characterised in that the energy module (24) has a handle (30, 108) at the upper end.

3. Industrial truck according to claim 1, characterised in that the energy module (24) has a housing (116) and the handle (108) is integrated in a contour of the housing (116) so that it does not protrude outwards over the housing (116).

4. Industrial truck according claim 1, characterised in that the battery receiving space has a base (38), a rear wall (40), two side walls and an upper wall (42), the energy module (24) in the defined installed position standing on the base (38) and having a curved upper contour (52) which is in contact with the upper wall (42).

5. Industrial truck according to claim 1, characterised in that the battery receiving space has a stop which cooperates with a mating piece on the energy module (24) and limits the tilting movement when the predetermined angle is reached.

6. Industrial truck according to claim 1, characterised in that the battery receiving space is integrated in the drive part (10).

7. Industrial truck according to claim 1, characterised in that at least one side surface (26) of the energy module and/or an upper surface (28) of the energy module (24) in the defined installed position is visible from outside and terminates substantially flush with an adjacent outer surface of a housing of the industrial truck.

8. Industrial truck according to claim 1, characterised in that during operation the industrial truck has a surface facing an operator, which is adjacent to the battery receiving space, and the energy module (24) is tilted in the direction of the operator.

9. Industrial truck according to claim 1, characterised in that a locking device (86) is provided which prevents the tilting of the energy module (24).

10. Industrial truck according to claim 9, characterised in that the locking device (86) has an actuation element (34) which is arranged so that it may be actuated by the hand gripping the handle (30) when the handle (30) is gripped.

11. Industrial truck according to claim 1, characterised in that resiliently pretensioned contacts are arranged on the energy module (24) or in the battery receiving space and which, when inserting the energy module (24), automatically produce an electrical connection between the energy module (24) and the industrial truck.

12. Industrial truck according to claim 1, characterised in that the energy module (24) has a battery management system and for producing an electrical connection for data exchange between the battery management system and the industrial truck further resiliently pretensioned contacts are arranged on the energy module (24) or in the battery receiving space which, when inserting the energy module (24), automatically produce an electrical connection between the energy module (24) and the industrial truck.

13. Industrial truck according to claim 1, characterised in that a charging station is present which has a battery receiving space which is the same as the battery receiving space of the industrial truck.
