Embodiment

[0021] Such as image 3 As shown, the present application proposes a lower hinge reinforcement for an automobile door, including a reinforcement body 5 arranged at the joint of the lower hinge of the door inner panel. In this embodiment, the door inner panel 11 is a non-tailored welded panel. The reinforcement body 5 includes a head 12 and a lower portion 13 that are integrally formed and bent at a certain angle.

[0022] The head 12 is positioned at the hinge side and sticks to the vertical inner sidewall at the bottom of the inner panel of the car door. The head 12 is provided with mounting holes 6 matched with the hinge, and the mounting holes 6 are provided with two vertically arranged. The front side of the mounting hole 6 is provided with a hinge nut plate 3, and the hinge nut plate 3 passes through the mounting hole 6 and is connected with the door inner panel by bolts. The head 12 is also provided with a limiting plate 9 that is bent toward the rear side of the reinf...

Abstract

The invention relates to an automobile door lower hinge reinforcing piece. The automobile door lower hinge reinforcing piece comprises a reinforcing piece body arranged at the joint of a lower hinge of an automobile door inner plate, wherein the reinforcing piece body comprises a head portion and a lower portion which are integrally formed and are bent with a certain angle formed, the head portionis attached to the vertical inner side wall at the bottom of the automobile door inner plate, the lower portion is attached to the transverse inner side wall at the bottom of the automobile door inner plate, the head portion is provided with a mounting hole matched with the hinge, and the two sides of the lower portion are provided with flanges which are bent upwards. Compared with the prior art,according to the automobile door lower hinge reinforcing piece, under the condition that the automobile door inner plate adopts a single 0.65-mm material thickness, rigidity and strength requirementsat the mounting point of the hinge can be met as well, the weight of the automobile door can be reduced by 2.1kg, the cost reduction effect is obvious, and meanwhile, the side surface collision performance of the whole automobile is improved.

Description

technical field [0001] The invention relates to the technical field of automobile bodies, in particular to an automobile door lower hinge reinforcement. Background technique [0002] In the general automobile body structure, the hinge reinforcement structure is adopted at the joint of the door hinge due to the stress concentration. At present, the car doors on the market are different in the size, material and installation position of the hinge reinforcement. The most common form is that the inner panel is in the form of a tailored welded blank. The thickness of the inner panel on the hinge side is 1.4mm, and that on the lock side is 0.7mm, so that the size of the hinge reinforcement can be smaller. The upper end and the lower end of the reinforcement body are provided with installation holes matched with the hinge, and flanges are arranged around it. [0003] A hinge reinforcement in the prior art such as figure 1 , figure 2 As shown, the reinforcement is small in size...
