Automobile threshold reinforcing structure

Abstract

The invention relates to an automobile threshold reinforcing structure. The automobile threshold reinforcing structure is characterized in that the automobile threshold reinforcing structure comprisesa top plate, a left side plate, a right side plate and a rear vertical plate; the top plate, the left side plate, the right side plate and the rear vertical plate form a semi-enclosing structure; flanging structures extending towards the outer sides are arranged at the upper ends, the front ends and the lower ends of the left side plate and the right side plate correspondingly; a groove structureis arranged on the top plate in the front-back direction, a groove opening of the groove structure faces downwards, and the outer surface of the groove bottom is higher than the upper plane of the top plate; and the threshold reinforcing structure is an integrated structure or a split type assembly structure. A same mould is used for the automobile threshold reinforcing structure in either of theintegrated structure or the split assembly structure, the design is reasonable, the structure is simple, stamping is easy, mechanical strength is high, safety performance is good, and side collisionperformance can be improved effectively; and compared with the prior art, the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of design, production and manufacture of auto parts, and in particular relates to a vehicle door sill reinforcement structure. Background technique [0002] The car's sill must have sufficient strength to support the lower part of the B-pillar in a side collision of the car. However, the threshold is prone to large deformation due to insufficient strength, or even bending phenomenon. In order to effectively solve the problem of the strength of the door sill, a reinforcement structure is usually provided on the inner side of the door sill of the vehicle. The reinforced structural member is directly facing the floor beam to improve the anti-deformation ability of the door sill when the car is in a side collision, so that the load can be effectively transmitted to the front and rear areas of the body and to the non-impact side through the floor mounting beam. Therefore, the door sill is very important in the ...
