Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0016] Such as figure 1 and figure 2 As shown, the front installation reinforcing plate of the front door anti-collision bar of the car has a plate body 1, and the plate body 1 is made of DC01 cold-rolled steel plate with a thickness of 1-1.5 mm. In this embodiment, the thickness of the plate body 1 is Preferably it is 1mm. Of course, as an equivalent replacement, the material of the plate body 1 can be replaced by other similar steel plates, and the thickness of the plate body 1 can be adjusted according to actual needs.

[0017] Such as figure 1 and figure 2 As shown, the board body 1 is composed of a first connecting piece 1a and a second connecting piece 1b. The first connecting piece 1a is in the shape of a "7" and is composed of a short arm section and a long arm section. One end of the short arm section is connected to the upper end of the long ...

Abstract

The invention discloses a front mounting reinforced plate of a front car door bumper bar. The front mounting reinforced plate comprises a plate body (1), wherein the plate body (1) comprises a first connecting piece (1a) and a second connecting piece (1b); the first connecting piece (1a) is 7-shaped; the short arm section at the upper end of the first connecting piece (1a) is vertically connected with the second connecting piece (1b); and a bump (1c) is arranged at the included angle formed by the first connecting piece (1a) and the second connecting piece (1b). The first connecting piece is designed to be 7-shaped and the bump is arranged at the included angle formed by the first connecting piece and the second connecting piece, so that the tensile deformation strength of the reinforced plate can be enhanced and the impact resistance can be improved; and the front mounting reinforced plate has the characteristics of simple structure, convenience for processing, low cost, good welding and positioning properties and the like, and is suitable for various vehicles.

Description

technical field [0001] The invention relates to an automobile door component, in particular to a reinforcement plate installed in front of an anti-collision bar on the front door of a car. Background technique [0002] At present, anti-collision bars are installed in the front side door panels of cars, and the two ends of the anti-collision bars are connected with mounting brackets, and a reinforcing plate is welded between the mounting brackets and the inner surface of the door panels. The existing reinforcing plate is composed of two flat plates perpendicular to each other, and is formed by one stamping, and the thickness of the material is generally less than 1 mm. The deficiency that above-mentioned stiffener exists is: [0003] 1) It is easy to be stretched and deformed by external force during use, which will weaken the anti-impact effect of the anti-collision bar; [0004] 2) The stress-relief effect at the angle between the two flat plates perpendicular to each oth...
