Summary of the invention
The purpose of this utility model proposes a kind of automobile B-pillar reinforcement plate assembly, can meet strength and stiffness requirement, can meet again the assembly precision requirement of arrangements for automotive doors; And quality is little, cost is low, and non-deformability is strong.
A kind of automobile B-pillar reinforcement plate assembly described in the utility model, comprise B column reinforcement plate, B column reinforcement plate is provided with upper hinge mounting hole and lower hinge mounting hole, described B column reinforcement plate adopts thermoforming process to make, B column reinforcement plate is fixed with the upper hinge brace panel and lower hinge stiffening plate be close to its inwall, described upper hinge brace panel is provided with first through hole corresponding with described upper hinge mounting hole, described lower hinge stiffening plate is provided with second through hole corresponding with described lower hinge mounting hole, sidewall and the sidewall of lower hinge stiffening plate of described upper hinge brace panel are equipped with the concave station do not contacted with described B column reinforcement plate.
Adopt technique scheme, above-mentioned B column reinforcement plate adopts thermoforming process to make, existing thermoforming process can realize the forming materials that tensile strength reaches more than 1000MP, and cold stamping shaped and laser assembly solder can realize the forming materials of tensile strength within 800MP at present.Therefore the B column reinforcement plate that thermoforming process is made can improve the bending strength of B column reinforcement plate assembly in automobile collision procedure greatly, reduces deflection.Upper hinge mounting hole and lower hinge mounting hole place arrange reinforcement respectively, improve the strength and stiffness that back door is installed, what reduce B column reinforcement plate is subject to force intensity, avoid the deflection of B column reinforcement plate, fall under effectively avoiding back door, improve automobile back door setting accuracy, improve the assembling quality at back door, except above-mentioned reinforcement, no longer set up other strengthen part, reduce welding level, optimize technological process, alleviate the weight of whole B column reinforcement plate assembly, to promote the realization of car load lightweight and energy-saving and emission-reduction.
Improve as one, described upper hinge mounting hole and lower hinge mounting hole all adopt the mode of laser beam cutting to make, laser beam cutting can lifting hole position precision greatly, avoids in prior art and easily occurs the problem that position, hole is out of shape ensure that the assembly precision of arrangements for automotive doors.
Improve as one, the sidewall of described upper hinge brace panel is alternate is provided with face of weld and the first concave station, described face of weld is close to the inwall of described B column reinforcement plate, the degree of depth of described first concave station is 2-5mm, because the first concave station does not contact with B column reinforcement plate, avoid upper hinge brace panel and B column reinforcement plate large area blind-mate, to avoid the overlap joint caused because element precision is not enough to interfere, quality of fit and efficiency of assembling can be improved.
Improve as one, the sidewall of described lower hinge stiffening plate is provided with the second concave station, the degree of depth of the second concave station is 2-5mm, because the second concave station does not contact with B column reinforcement plate, avoid upper hinge brace panel and B column reinforcement plate large area blind-mate, to avoid the overlap joint caused because element precision is not enough to interfere, quality of fit and efficiency of assembling can be improved.
Further, described upper hinge brace panel and lower hinge stiffening plate are fixed on described B column reinforcement plate by the mode of welding, to ensure that junction coordinates for Zero clearance.
In sum, this automobile B-pillar reinforcement plate assembly can meet strength and stiffness requirement, can meet again the assembly precision requirement of arrangements for automotive doors; And quality is little, cost is low, and non-deformability is strong, safety and economical.
