Abstract

The invention discloses a door ring reinforcing frame assembly of a two-door electric vehicle, which comprises an A column assembly, a rear side wall inner plate assembly, a doorsill assembly and a B column reinforcing plate, the rear end of the top of the A column assembly is fixed to the front end of the top of the rear side wall inner plate assembly, and the top of the B column reinforcing plate is fixed to the rear side wall inner plate assembly in a two-layer mode. The front side and the rear side of the B column reinforcing plate are fixed to the front portion of the rear side wall inner plate assembly in a two-layer mode, the lower end of the B column reinforcing plate is fixedly connected with the doorsill assembly, and the lower portion of the front end of the rear side wall inner plate assembly is detachably fixed to the upper portion of the rear end of the doorsill assembly. The front end of the doorsill assembly is fixedly connected with the bottom of the A column assembly. The door ring reinforcing frame assembly of the two-door electric vehicle is simple in structure, the B column is reinforced, the side collision and column collision performance is improved, the requirement for the mounting rigidity of the vehicle door is met, the problem of stress concentration of the door frame is solved, the risk of welding spot cracking is reduced, the cost is reduced, and the safety of passengers and batteries is protected.

Description

Technical field [0001] The present invention relates to a field of automotive body technology, in particular to a two-door electric car door ring plus strong frame assembly. Background technique [0002] The prior art lateral door ring enhancement frame is typically connected to the A column to reinforce plates 1 ', the A column reinforcing plate 2', the B-column reinforcing plate 3 'and the outer plate reinforcing plate 4' are connected to each other, two electric motors There are two technical solutions for the car side gate ring enhancement frame: [0003] Plan figure 1 , figure 2 As shown, its main shortage is: [0004] 1, the lower end of the B-column reinforcing plate 3 'and the sill exterior reinforcing plate 4' rear end does not match, in the B-column end door ring enhancement frame is disconnected here, the overall stiffness is weak, the conversion of the collision force is not continuous, the deformation is more Big; [0005] 2, the door ring enhancement frame is discon...
