Energy store floor assembly
An energy store floor assembly for an electrically driven motor vehicle includes an electrical energy store device, which is accommodated in a multi-part store housing and is situated on the underside of a vehicle floor of the energy store floor assembly. To create an energy store floor assembly which can be constructed in a more simple and lightweight manner, at least one longitudinal support is arranged inside the store housing of the energy store device and is connected at least at one end at least indirectly to a motor vehicle support component situated in the region of the front end.
1. An energy store floor assembly for an electrically drivable motor vehicle, comprising:
a vehicle floor of the energy store floor assembly;
a store housing in which an electrical energy store device is accommodatable, the store housing being arranged on an underside of the vehicle floor of the energy store floor assembly;
at least one longitudinal member arranged inside the store housing of the energy store device, the at least one longitudinal member being connected indirectly at at least one end to a support component of the motor vehicle arranged in a region of a front end of the motor vehicle;
a wall region of the vehicle floor arranged between the at least one longitudinal member and the support component,
wherein the support component is not part of the store housing.
2. The energy store floor assembly according to claim 1 , wherein
the vehicle floor is configured as a housing part of the store housing and is connected to at least one further lower housing part of the store housing via at least one gastight connection.
3. The energy store floor assembly according to claim 2 , wherein
the at least one longitudinal member is fastened on the underside to the vehicle floor.
4. The energy store floor assembly according to claim 3 , wherein
the at least one longitudinal member is connected to a further longitudinal member which is arranged below the at least one longitudinal member and which is connected to the further lower housing part of the store housing.
5. The energy store floor assembly according to claim 3 , wherein
the at least one longitudinal member runs over the entire height of the store housing and is connected to the further lower housing part of the store housing.
6. The energy store floor assembly according to claim 1 , wherein
the at least one longitudinal member is connected to at least one crossmember running on an upper side of the vehicle floor.
7. The energy store floor assembly according to claim 1 , wherein
the vehicle floor together with the at least one longitudinal member is designed as part of a painted motor vehicle body shell.
8. The energy store floor assembly according to claim 1 , wherein
the vehicle floor is connected non-releasably to the at least one longitudinal member.
9. The energy store floor assembly according to claim 8 , wherein
the connection is an integrally bonded connection.
10. The energy store floor assembly according to claim 9 , wherein
the integrally bonded connection is a welded connection or an adhesive connection.
11. The energy store floor assembly according to claim 1 , wherein
the at least one longitudinal member is connected at least indirectly to the support component of the motor vehicle in a manner free from play.
12. The energy store floor assembly according to claim 11 , wherein
the connection is an integrally bonded connection.
13. The energy store floor assembly according to claim 12 , wherein
the integrally bonded connection is a welded connection or an adhesive connection.
14. The energy store floor assembly according to claim 1 ,
wherein the vehicle floor is configured as a housing part of the store housing and is connected to at least one further lower housing part of the store housing,
wherein a region of the front end of the vehicle floor comprises a flange that merges, via an obliquely running wall that forms the wall region, into a flat region of the vehicle floor,
wherein the flange is connected to a corresponding flange of the further lower housing part, whereby the at least one longitudinal member is connected indirectly by the obliquely running wall forming the wall region to the support component.
