Specific embodiment
Fig. 1 to Fig. 6 with reference to the accompanying drawing is further detailed to a kind of groined type car body rolling protective device of the invention
Explanation.
A kind of groined type car body rolling protective device of the invention, please refers to shown in Fig. 1 to Fig. 6, including A column hog frame 1,
Crossbeam hog frame 2 and B column force transmission rack 3,2 left and right ends of crossbeam hog frame and the A column hog frame 1 are fixed, and the B column passes
3 top of power frame is fixed with 1 middle and back of A column hog frame, and the A column hog frame 1 is extended in the vehicle body A column 7, institute
Stating vehicle body A column 7 includes A column column 5, and 1 front end of A column hog frame is fixed on 5 upper end of A column column, 1 tail of A column hog frame
End and the side girders 8 between B column 6 and C column are fixed, and the B column force transmission rack 3 is fixed on inside 6 upper end of B column, the crossbeam
Hog frame 2 is arranged in car body top cover beam 18.Specifically, A column hog frame 1, crossbeam hog frame 2 and B column force transmission rack 3 are distinguished
The A column hog frame 1, B column force transmission rack 3 and crossbeam in vehicle body A column 7, in car body top cover beam 18 and in center body pillar 6 are set
Hog frame 2 is high-pressure molding reinforcement structure, and whole is in groined type, through the weaker A column 7 of vehicle body, roof bow 18, pole
The big intensity for improving vehicle A column 7, roof bow 18 guarantees have completely in the vehicle body sheet metal junction of each weakness
High reinforcement structure improves reliability, and the fixation can be freezed fixation by nesting, and vehicle is easy to happen change when rolling
The form of shape is divided into two kinds, the first is that A column 7 and roof bow 18 are deformed along Z axis to the conquassation below vehicle, for the first
Deformation, when A column 7 is by the impact under Z-direction, on the one hand curved A column hog frame 1 absorbs main impact force, A column
After hog frame 1 is impacted, institute's bending moment can prolong A column hog frame 1 and a part of load is transmitted to A column column 5 and A
On column 7 and side girders 8, and passes through B column force transmission rack 3 and a part of load is transmitted on B column 6, then be transmitted under car body
On the load-carrying construction in portion, in addition the moment of flexure of the larger side of load can be transmitted to the lesser side of stress by crossbeam hog frame 2.Pass through
The above effect, effectively reduces the deflection of A column 7 and roof bow 18, guarantees living space；Second is deformed, when A column 7
By the impact inside from Y direction, on the one hand by the way that a part of moment of flexure can be born in the middle part of A column hog frame 1, punching is absorbed
It hits, the crossbeam hog frame 2 that front end is on the other hand arranged in has very strong hardness along axial, absorbs most impact force, has
Effect is resisted A column 7 and is deformed, and guarantees living space, increases substantially bodywork safety.A kind of groined type car body of the invention, which rolls, to be protected
Protection unit, compared with the existing technology the advantages of be: effectively improve the intensity of vehicle A column 7 and roof bow 18, reduce roll procedure
The conquassation of middle A column 7 and roof deforms, so that living space be effectively guaranteed, reduces the occupant as caused by rollover accident
Injury, to improve vehicle central collision and side impact intrusion volume provide booster action, effectively avoid consumer's life and property loss with
And traffic mortality.
A kind of groined type car body rolling protective device of the invention, please refers to the skill shown in Fig. 1 to Fig. 6, described in front
