The structure of the reinforcement girder construction to the utility model body bottom and principle are described in detail below.
Fig. 1 is shown to be shown according to the overall structure of the reinforcement girder construction of the body bottom of the utility model exemplary embodiment
It is intended to.
As shown in figure 1, according to exemplary embodiment of the present utility model, the reinforcement girder construction of the body bottom include by
Floor crossmember assembly 2, the left longeron assembly 1 in rear floor, rear floor right vertical beam assembly 3 and front and rear floor connecting plate assembly 4 splice afterwards
The frame assembly and the left inclined strut beam assembly 6 being arranged in the frame assembly and right inclined strut beam assembly 5 formed, wherein, it is left oblique
Strutbeam assembly 6 is arranged between the left longeron assembly 1 in rear floor and rear floor crossmember assembly 2 and forms left side triangle reinforcement structure,
Right inclined strut beam assembly 5, which is arranged between rear floor right vertical beam assembly 3 and rear floor crossmember assembly 2 and forms right side triangle, strengthens knot
Structure.
Said structure is taken into account while mount points of the battery bag X to limiting bracket is provided and improves rear overhang peace on vehicle body
The rigidity decorateeed, and when being extended to fuel vehicle platform, the rigidity of structure for strengthening the position of girder construction remain to meet to require (by
It is less than electric car in fuel vehicle axle load).
Fig. 2 shows the action principle schematic diagram of left side triangle reinforcement structure in the reinforcement girder construction of body bottom in Fig. 1.
Because the reinforcement girder construction is substantially symmetrical, only schematically illustrated herein with left side.
Left inclined strut beam assembly 6, the left longeron assembly 1 in rear floor constitute a triangle in left side with rear floor crossmember assembly 2
Reinforcement structure, the left mount point 7 of towing arm to rear overhang assembly, the left mount point 8 of helical spring play rigidity booster action respectively.Together
When, the X of battery bag may be provided at right inclined strut beam assembly 5, on left inclined strut beam assembly 6 to limiting bracket (not shown).Fired in extension
During oily car platform, removal inclined strut beam assembly 5 and left inclined strut beam assembly 6 are only needed, is connected on rear floor crossmember assembly 2, front and rear floor
Fuel tank mount point is set to meet fuel tank space requirement on plate assembly 4.
According to the utility model, the reinforcement girder construction can also include being arranged on left inclined strut beam assembly 6 and right inclined strut beam is total
Into the battery bag X on 5 to limiting bracket (not shown).The triangle reinforcement structure of both sides is respectively to rear overhang in above-mentioned reinforcement girder construction
The towing arm of assembly, helical spring installation light rigidity booster action, while provide installations of the battery bag X to limiting bracket
Point, it disclosure satisfy that the X of battery bag to limit function.
Also, left inclined strut beam assembly 6 and right inclined strut beam assembly 5 can be removed and by the rear Hes of floor crossmember assembly 2
The fuel tank mounting bracket set up on front and rear floor connecting plate assembly 4 and expand to fuel vehicle platform.Thus, by becoming less amount zero
Part can is expanded to the structure type of fuel vehicle by electric vehicle body skeleton, and generalization, hardware and software platform degree are higher, by a relatively large margin
Ground reduces mould, fixture cost.
Wherein, left inclined strut beam assembly 6 and right inclined strut beam assembly 5 can use two kinds of different structure types to meet difference
Demand.
Specifically, left inclined strut beam assembly 6 and right inclined strut beam assembly 5 can be formed by the inclined strut beam assembly of an entirety,
Other structures are identical.When using the overall structure, amount of parts is less and cost is lower, but precision controlling to part and
The requirement of welding procedure is higher.
Left inclined strut beam assembly 6 and right inclined strut beam assembly 5 can also be by leading portion inclined strut beam assemblies and back segment inclined strut beam assembly
Composition, wherein, leading portion inclined strut beam assembly longeron assembly 1 left with rear floor or rear floor right vertical beam assembly 3 are connected, back segment inclined strut beam
Assembly is connected with rear floor crossmember assembly 2.When using the segmental structure, more meet technological requirement and control accuracy and Welder
Skill requires relatively low.
In addition, the reinforcement girder construction of said structure can also have a certain upgrade to the twisting property of vehicle body.
In summary, the reinforcement girder construction of body bottom of the present utility model can meet battery X to limit function
Meanwhile take into account the effect of lifting body overhang attachment point rigidity；By becoming less amount part can by electric vehicle body skeleton
The structure type of fuel vehicle is expanded to, generalization, hardware and software platform degree are higher, greatly reduce mould, fixture cost.
The utility model is not limited to foregoing embodiment.The utility model expands to any in this specification
The new feature of middle disclosure or any new combination, and disclose any new method or process the step of or any new group
Close.
