Specific embodiment
A kind of body of a motor car skeleton of the present invention is further described with reference to specific embodiment, wherein along by it is left extremely
Right direction is longitudinal direction and longeron direction, and along being laterally with crossbeam direction by the direction of vertical paper outside to inside, edge is from top to bottom
Direction be vertical and vertical beam direction.
As shown in Figs. 1-2, a kind of body of a motor car skeleton of the invention, including front cabin skeleton 1, battery stateroom skeleton 2, deck store
Skeleton 3 and roof rail 14；1 rear end of the front cabin skeleton is fixedly connected with the front end of the battery stateroom skeleton 2, the battery pack
The rear end of cabin skeleton 2 is fixedly connected with the front end of the deck store skeleton 3, the rear and front end of the roof rail 14 respectively with it is described before
Cabin skeleton 1 is fixedly connected with the deck store skeleton 3；The middle and back of the battery stateroom skeleton 2 is equipped with 8 He of battery stateroom front beam
The both sides of battery stateroom rear cross beam 9, the battery stateroom skeleton 2 are equipped with jack stringer 6 and interior beam 7；6 He of the jack stringer
The both ends of the interior beam 7 are fixedly connected with battery stateroom front beam 8 and battery stateroom rear cross beam 9 respectively；The interior beam 7
In the inside of the jack stringer 6,7 one end of the interior beam is tilted to 6 one end of the jack stringer, the interior beam 7 and described outer
Acute angle is formed between longeron 6；The interior beam 7 of both sides is formd with battery stateroom front beam 8 and battery stateroom rear cross beam 9 can
For the hollow fixed frame that battery pack is packed into from the bottom to top, the battery pack is fixedly connected with the fixed frame.In this way, independent
2 structure of battery stateroom skeleton, facilitates arrangement and the installation of battery pack；Battery pack is packed into from lower to upper from fixed frame, and electricity
Chi Bao can be fastened by bolts on the Zhou Bianliang of fixed frame；Fixed frame is the matter that hollow structure reduces battery stateroom skeleton 2
Amount, ensure that the lightweight of integral body.Meanwhile battery stateroom skeleton 2 is located at vehicle centre position, front cabin skeleton 1 and deck store
Skeleton 3 is respectively before and after vehicle body；Due to the setting of 3 structure of front cabin skeleton 1 and deck store skeleton in normal impact, collision impact is played
The effect of buffering, to reduce automobile central collision, after touch when to the impact force of battery pack, to improving the peace of battery pack
Full performance.7 one end of the interior beam is tilted to 6 one end of the jack stringer, is formed between the interior beam 7 and the jack stringer 6
Acute angle.In this way, foring a stable class triangular structure between interior beam 7, jack stringer 6 and battery stateroom rear cross beam 9.By
There is stability in triangular structure, so that battery stateroom skeleton 2 not only meets the secured installation of battery pack；Also to vehicle body
Play the role of stablizing support, when reducing vehicle side impact, the deformation of body structure plays buffering to battery pack impact force and makees
With.
Referring to attached drawing 1-2, a kind of body of a motor car skeleton of the invention based on the above technical solution, Ke Yishi：Into
One step the preferred technical solution may also be：The both sides of the front cabin skeleton 1 are respectively equipped with reach the front cabin skeleton 1 before it is outer
Lateral Guard Assy 4 is fixedly installed on two longerons in the longeron in portion；The both sides of the deck store skeleton are respectively equipped with stretching
Lateral Grard Assy 5 is fixedly installed on two longerons in external longeron after to the deck store skeleton.In this way, due to preceding
Crash bar 4 and Grard Assy 5 are reached respectively outside front cabin skeleton 1 and deck store skeleton 3 so that 2 position of battery stateroom skeleton away from
Farther out from Guard Assy 4 and Grard Assy 5, in maximum distance to collision play cushioning effect, reduce in an impact to
The danger that battery pack is brought.Further technical solution can also be：The height of the Guard Assy 4 and the Grard Assy 5
Degree is above the height of the fixed frame.In this way, when vehicle generation central collision is touched with after, front cabin skeleton 1 and deck store skeleton 3 occur
Deformation, has slackened the direct impact to battery pack, even explodes to avoid battery pack from catching fire because of collision.
Referring to attached drawing 1-2, a kind of body of a motor car skeleton of the invention based on the above technical solution, Ke Yishi：Institute
It states floor stand beam 10 and seat frame 11, the seat frame 11 before being integrated on battery stateroom skeleton 2 and is fixed on both sides
On the interior beam 7 and the battery stateroom rear cross beam 9, the both ends of the preceding floor stand beam 10 respectively with the battery stateroom
Front beam 8 and preceding floor crossmember 15 are fixed.In this way, by battery stateroom integrated seat frame 11 and preceding floor stand beam 10, it is whole
Body simplifies the design of body frame, improves the integrated level of battery stateroom skeleton 2；It is integrated simultaneously to increase connection and support,
Improve the stability and reliability of integral body skeleton.
Referring to attached drawing 1-2, a kind of body of a motor car skeleton of the invention based on the above technical solution, Ke Yishi：Institute
The both sides of the both sides and rear end of stating the front end of battery stateroom skeleton not She You preceding vertical beam 12 and rear vertical beam 13,12 He of preceding vertical beam
Vertical beam 13 is fixedly connected with the front and rear of the roof rail 14 respectively after described.In this way, passing through the preceding vertical beam 12 and institute
It states rear vertical beam 13 and plays the role of support to roof rail 14, increase the stability of roof rail 14.Further technical solution
It can also be：It is described after vertical beam 13 inclination is fixed on the jack stringer 6, it is described after between vertical beam 13 and the jack stringer 6
Angle is acute angle.In this way, the rear vertical beam 13 being obliquely installed avoids the position that the fixed frame fixes battery pack, battery pack can be with
Visualization is fixed, convenient for the fastening and adjustment to battery pack.Further technical solution can also be：The front cabin skeleton
1, the battery stateroom skeleton 2 and the deck store skeleton 3 are all made of aluminium section bar and are made.In this way, the body frame structure for automotive of aluminium section bar, reduces
Complete vehicle quality, realizes vehicle lightweight；The loss for reducing energy, to improve duration performance.Further preferred
Technical solution can also be：It is described to be fixedly connected using being welded and fixed or rivet fixation.This way it is ensured that the rigidity of body frame
Intensity, meanwhile, production technology in the prior art has fully been used, the design of production line has been simplified, reduces production cost.
It is above-mentioned that only a kind of specific embodiment in the present invention is illustrated, but can not be as the protection model of the present invention
Enclose, it is every according to the present invention in design spirit made by equivalent change or modification, be deemed to fall the present invention protection
Range.
