Preferably, left/right oblique pull beam and the left/right crossbeam when crossbeam tie point is close to vehicle frame left/right longeron and left/right Tie point.
Preferably, left/right oblique pull beam is connected with left/right side crossbeam using welding, riveting.
Preferably, left/right oblique pull beam respectively with luggage compartment left/right longitudinal beam welding.
Preferably, the cross section of left/right oblique pull beam is " π " type, and Open Side Down, and the cross section of luggage compartment left/right longeron is " π " type, opening upwards.
Preferably, blocking means are baffle plate or K-type structure after battery flat.
The present invention has the advantages that compared with prior art:
1st, the technical program is total to by longitudinal beam, battery flat column and vehicle frame back segment oblique pull beam due to battery flat assembly part With stable spatial triangle structure is formed, it can not only strengthen the bending resistance of whole vehicle frame, can have during being touched after Effect impulsive force is transmitted on longeron, so as to mitigate the vehicle body extent of damage, reduces the deflection of vehicle body, ensures to greatest extent The safety of in-car member.
2nd, the battery flat of the technical program is arranged in the junction of front section of vehicle frame and back segment, is herein bus body strength and rigidity Maximum place, can effectively ensure the safety of battery, prevent battery from being caused danger in collision process.
3rd, the left/right oblique pull beam lower end of the technical program is connected with left/right side crossbeam respectively, and stabilization is formed using battery flat Spatial triangle structure strengthen the installation strength of rear suspension, ensure that the riding stability of vehicle, it is antitorque to improve vehicle body Turn and counter-bending level, while due to the increase of body tail strength and stiffness, energy is touched after can effectively absorbing when touching after occurring Amount.
