Background technology
What generally know in the self-propelled vehicle manufacturing is that the base arrangement of vehicle body is reinforced by side sill (being side Kan Liang) and middle kerve along the longitudinal direction of car direction in the zone in main cabin.Mostly realize needed reinforcing by so-called heel slab (Fersenblech) on vehicular transverse direction, this heel slab is extending along vehicular transverse direction between two side sill below the back row seats.In the zone in front, realize reinforcing in vehicular transverse direction by end wall, this end wall has formed the front border in main cabin simultaneously.
Be different from the vehicle of traditional combustion engine at the driving design plan, the problem that proposes for car construction is where needed energy storage can be placed in.So for example be known that by DE102009006990A1 and in middle kerve, settle a battery module.The advantage that this mode is brought is that the center of gravity of vehicle is lower, because heavier battery module is arranged in the zone of vehicle floor.On the other hand, when having an accident, the battery module in the middle kerve not only from the side but also from the front or the back all be subject to fine protection in case stop loss wound.
Summary of the invention
The object of the invention is to, create a kind of vehicle body of self-propelled vehicle, this vehicle body has high rigidity and can settle well energy storage on this vehicle body.
The vehicle body of the self-propelled vehicle of above-mentioned purpose by having claim 1 feature is achieved.
According to the present invention, the vehicle body of self-propelled vehicle has base arrangement in the zone in main cabin, medially can settle energy storage along the vehicular transverse direction observation on the bottom side of this base arrangement.This energy storage for example can be battery module or high pressure accumulator.This base arrangement along vehicular transverse direction observe have in the centre extend along the longitudinal direction of car direction and along the bridging board of the downward projection of vehicle-height direction.
Energy storage occupies many structure spaces in the baseplate zone of self-propelled vehicle, realize that in addition the body structure of reinforcing also requires to utilize this structure space.Although still should have high rigidity and be provided with energy storage according to vehicle body of the present invention in the bottom side of base arrangement.Bridging board has just improved the bending stiffness of base arrangement.
Preferably, base arrangement has in the zone of energy storage at least along vehicle-height direction observes protrusion upwards, and this protrusion is observed medially along the extension of longitudinal direction of car direction and along vehicular transverse direction and arranged.Additionally, protrusion can be reinforced by brace panel fixed thereon, and this brace panel extends along the longitudinal direction of car direction equally.Bridging board can advantageously be placed in the protrusion.At this, this bridging board exceeds base arrangement as keel neighboring region extends along the downward projection of vehicle-height direction and along the longitudinal direction of car direction.Except bridging board, protrusion upwards additionally improves the rigidity of vehicle floor in case of necessity greatly with brace panel.
It is desirable to, the energy storage of settling on the bottom side of base arrangement has and recess along trend from vehicle-height direction to downward-extension according to the longitudinal direction of car direction, and bridging board shape abuts in this recess in locking manner.Thus energy storage shape is connected in locking manner.Bridging board also can be used for connecting the constraint energy storage.
Advantageously, have respectively a longeron to extend along the longitudinal direction of car direction in the both sides of energy storage, this longeron and energy storage are adjacent.Already advantageously verified, energy storage medially is arranged on below base arrangement in the zone in main cabin.So the front railway carriage or compartment of self-propelled vehicle and rear railway carriage or compartment are used as the wrinkle Zhe district (Knauschzone) of head-on crash and afterbody collision, thereby so that the main cabin is protected together with the energy storage that arranges in its lower section, needs only the main cabin and have enough rigidity.When side collision, the major part of energy is absorbed by the side sill.At this, energy storage does not extend to the side sill according to the present invention in side direction always, because longeron also must have the position between them.Thus, arranging in the structure by of the present invention, even energy storage also obtains good protection in the side collision situation.Longeron helps to improve the global stiffness of vehicle body very significantly.
Advantageously, the end regions of the back of two longerons is connected with a heel slab, and this heel slab extends below back row seats along vehicular transverse direction.Energy storage is in this and heel slab adjacency.In front, two longerons are preferably put crossbeam with an end and are connected, and put crossbeam and extends along vehicular transverse direction at this end.Energy storage is also put the crossbeam adjacency with this end.Crossbeam is put at longeron, heel slab and the end by adjacency, can not only derive the application force in the energy accumulator area on the longitudinal direction of car direction but also in vehicular transverse direction.Moreover because the intrinsic rigidity of energy storage, the part of application force can be transmitted through energy storage itself by the beam of adjacency.
Other favourable design plan is the subject content of dependent claims.
Description of drawings
A kind of embodiment of the present invention shown in the drawings, the below describes the present invention in detail by this embodiment.Each accompanying drawing represents schematically:
Fig. 1 illustrates the transparent view that motorcar body is observed from below;
Fig. 2 illustrates the cross-sectional perspective view of the vehicle body shown in Fig. 1;
Fig. 3 illustrates the schematic cross-section of the vehicle body that goes out among Fig. 1.
The specific embodiment
The vehicle body 1 of self-propelled vehicle is shown in the drawings, and this vehicle body is with high pressure accumulator 2.High pressure accumulator 2 is used for the electric drive of self-propelled vehicle is carried out Power supply as energy storage.This high pressure accumulator 2 is placed in the zone in main cabin on the bottom side of base arrangement 3 of vehicle body.This high pressure accumulator on vehicle-height direction z based on given structure space relation but more flat, thus on the one hand so that the base plate degree of freedom of self-propelled vehicle is unrestricted, and thus on the other hand so that self-propelled vehicle can not make up too highly (making up to such an extent that height is undesirable).High pressure accumulator 2 medially arranges on vehicular transverse direction y, thus so that the weight G of high pressure accumulator 2 evenly distribution on both sides.High pressure accumulator 2 is extending more than 2/3rds of vehicle width along vehicular transverse direction y.And still leaving the clearance envelope of opposite side sill 4 in high pressure accumulator 2 both sides, these side sill limit the border of base arrangement 3 in side direction in the zone in main cabin.Along longitudinal direction of car direction x, high pressure accumulator 2 is placed in the zone of below, main cabin.At this, this high pressure accumulator is more than extending in the zone in the main cabin on half of base arrangement 3 longitudinal extension length.
This set structure of high pressure accumulator 2 has advantages of very large under collision situation: when head-on crash or afterbody collision; high pressure accumulator 2 is protected by the front railway carriage or compartment 5 of vehicle body or by the rear railway carriage or compartment 6 of vehicle body; so the front railway carriage or compartment of self-propelled vehicle and rear railway carriage or compartment are as wrinkle Zhe district; so that protection main cabin and also protect thus base arrangement 3 in the cabin zone, be mounted with high pressure accumulator 2 herein.In the side collision situation, side sill 4 are intercepted and captured the major part of collision effect.This most collision effect also has some and invades to vehicle center, and then it is damaged to high pressure accumulator 2.
In traditional vehicle body, middle kerve has been contributed pith for realization vehicle body global stiffness.In the middle of this kerve shown in motorcar body in since settle in its lower section high pressure accumulator 2 so no longer can realize like this, because there is not essential height available.In order to compensate this loss of rigidity, have additional structure according to vehicle body of the present invention now:
Replace typical middle kerve, the base arrangement 3 of vehicle body has in the zone of high pressure accumulator 2 at least along vehicle-height direction z observes protrusion 19 upwards, and this protrusion is observed medially along longitudinal direction of car direction x extension and along vehicular transverse direction y and arranged.This protrusion 19 is also additionally reinforced by brace panel 22 on upside.This brace panel 22 is observed in cross-sectional plane has the shape of inverted " W ".This brace panel observes in cross-sectional plane that end section and the section by the centre are connected with protrusion 19 freely by two.Be provided with the bridging board 20 that be open upwards, U-shaped along vehicle-height direction z in protrusion 19, this bridging board exceeds base arrangement 3 as keel neighboring region extends along the downward projection of vehicle-height direction z and along longitudinal direction of car direction x.
A longeron 7 is arranged respectively in the both sides of high pressure accumulator 2 directly and high pressure accumulator 2 extend adjacently.Each longeron 2 forms by the plate members of hat respectively, and this plate members is placed on the base plate with two edge section.This longeron 7 is parallel to side sill 4 along longitudinal direction of car direction x and extends and be connected with the vehicle body of remainder respectively by its end section.For this reason, the rearward end of two longerons 7 is connected with a heel slab 8.This heel slab is extending in the zone below back row seats between two side sill 4 along vehicular transverse direction y.This heel slab 8 defines the foot well backward for the back row seats passenger at longitudinal direction of car direction x.High pressure accumulator 2 is same and heel slab 8 adjacency along longitudinal direction of car direction x.In front, beam 9 adjacency are put at high pressure accumulator 2 and an end.Put beam and extend between two side sill 4 along vehicular transverse direction y at this end.Two longerons 7 are put beam 9 with this end equally and are connected.But they continue forward above high pressure accumulator 2 and forward continuity surpass the end and put beam 9 and be supported on respectively on the main longitudinal grider 10 in front railway carriage or compartment 5.
High pressure accumulator 2(is as Fig. 3 midship section can be clear that) have a recessed otch 21, it extends in the whole length of high pressure accumulator 2 along longitudinal direction of car direction x.This recessed otch 21 is sealed with a kind of shape of bridging board 20 formation.High pressure accumulator 2 is connected on the longeron 7 and in the centre in side direction and is connected on the bridging board 20 via a plurality of connection restraint devices (connecting the constraint point) A along vehicle-height direction z.Additional connection restraint device A by on bridging board 20 has guaranteed that heavier high pressure accumulator 2 in respectively connecting between the restraint device A of side direction runout can occur desirably.
Additionally, two driving device longerons 11 are put between beam 9 and the end wall crossbeam end of at along longitudinal direction of car direction x and are extended, and this end wall crossbeam extends along end wall 12 on vehicular transverse direction y, and this end wall forms the front border in main cabin.Also supporting axle beam 13 on this driving device longeron 11, this axle beam is used for accepting the front axle of self-propelled vehicle.
Observe along longitudinal direction of car direction x, putting the end of between beam 9 and the heel slab 8 has respectively a supporting member 14 that extends along vehicular transverse direction y in both sides, and this supporting member is supported on longeron 7 on the side sill 4.
Vehicle body with the car of high pressure accumulator 2 all has advantages of very large by structure of the present invention for all crash typees.In the situation that head-on crash, front railway carriage or compartment 5 absorbs the most of of collision energy and deforms simultaneously.Main cabin and the high pressure accumulator 2 of being located at below it should keep injury-free as far as possible.For this reason, base arrangement 3 must have corresponding high rigidity in the zone in main cabin.Especially the brace panel 22 of bridging board 20, protrusion 19 and W shape helps to realize this rigidity.And two longerons 7 have also improved the rigidity of base arrangement 3 on longitudinal direction of car direction x.The base arrangement 3 that obtains like this reinforcing is being delivered in the heel slab 8 along the application force back kick that longitudinal direction of car direction x imports by head-on crash.At this, some application force is exported backward by the bearing-type housing of high pressure accumulator 2.The rigidity of needed high pressure accumulator 2 housings is also guaranteed by stringer board bar 17 placed in the middle for this reason.Under the afterbody collision situation, power stream (being the power transfer route) is similar with the situation of head-on crash, but is to carry out with opposite direction.
In the situation that side collision, load enters into side sill 4 along vehicular transverse direction y.These side sill 4 are supported in front on A post and the end wall 12, are supported on the heel slab 8 in the back along longitudinal direction of car direction x observation.Between it, side sill 4 are supported on the end and put on the beam 9.That is to say, application force enters into the A post or enters into end wall 12, the end puts beam 9 and heel slab 8.Additionally, the part of application force is delivered in the longeron 7 via supporting member 14.This longeron be bearing in again then that the end puts on the beam 9 and heel slab 8 on.Additionally, longeron 7 with have high pressure accumulator 2 adjacency of stiff case.The application force that imports in the high pressure accumulator 2 partly is passed in the bridging board 20 and partly is passed in the opposed longeron 7 via shape is sealed.At this, the partition wall 18 of high pressure accumulator 2 has significant contribution for rigidity on vehicular transverse direction y.Thus, on vehicular transverse direction y, also has high rigidity by the motor vehicle with high pressure accumulator 2 of the present invention.
Remedy the disappearance of traditional middle kerve by structure of the present invention fully, thereby can not cause loss of rigidity.
