Upper support frame of automobile dashboard crossbeam

Abstract

The invention discloses an upper support frame of an automobile dashboard crossbeam. The upper support frame comprises a support frame body and a mounting plate which are integrally formed by punching. The support frame body is of a flat plate structure, small sections of lower turnups are arranged at two side edges of the support frame body respectively to serve as reinforcing ribs, and thus, the cross section of the support frame body is C-shaped. Two wing-shaped plates and a pair of welding plates are arranged on two sides of the front portion of the support frame body, the wing-shaped plates extend downwardly along the reinforcing ribs, and the welding plates are connected to the front lower ends of the wing-shaped plates respectively. The mounting plate is smoothly connected to the rear end of the support frame body, and an included angle larger than 90 degrees is formed between the mounting plate and the support frame body. Small sections of front turnups are arranged at two side edges of the mounting plate respectively to serve as reinforcing ribs, and thus, the cross section of the mounting plate is C-shaped. The upper support frame of the automobile dashboard crossbeam is improved greatly in terms of cost, technique and strength and has good mounting effect and high stability.

Description

technical field [0001] The invention relates to an automobile part, in particular to an upper support frame of an automobile dashboard beam. Background technique [0002] The instrument panel beam spans the cockpit of the car. It is an important load-carrying mechanism on the car. It is mainly installed with car instruments, electrical components, safety airbags and steering systems. The cabin acts as a reinforcement. There are positioning pins and some heavy sheet metal brackets on the crossbeam of the instrument panel. The upper support frame is one of the sheet metal brackets, which has the function of providing installation, support and fixation for other auto parts on the instrument panel beam. The existing upper support frame is a zigzag arc-shaped plate. In order to increase the strength, reinforcement ribs must be added at the welding place with the main beam of the instrument panel. The gap is unstable, and welding defects will also be caused after welding. In ad...

AI Technical Summary

Problems solved by technology

The existing upper support frame is a zigzag arc-shaped plate. In order to increase the strength, reinforcement ribs must be added at the welding place with the main beam of the instrument panel. The gap is unstable, and welding defects will also be caused after welding. In addition, the structure of the upper support frame itself is relatively complicated, and the cost of the mold will increase immediately, and the manufacturing cycle will be lengthened. However, the overall process is complicated, the development cost will increase, and the development cycle will be extended.
