Problems solved by technology

When the side of the car is subjected to a strong collision, the center pillar of the existing structure is easily deformed due to the small force-bearing surface on the side and the small buffer area, thereby impacting and crushing the occupants in the car, especially the heads of the front occupants. and shoulders

Embodiment Construction

[0023] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0024] like figure 1 , figure 2 and Figure 8 As shown, the present invention is a center pillar of an automobile body with a reinforced structure, which is mainly composed of a center pillar reinforcement plate 1, a safety belt fixing reinforcement plate 2, a seat belt nut plate 3, a side wall outer plate 4 and a center pillar inner plate 5 . Among them, the side wall outer panel 4, the center pillar reinforcement plate 1 and the center pillar inner panel 5 are sequentially welded into one body. The notches of the outer panel 4 and the inner panel 5 of the center column are opposite to enclose the forming cavity, and the center column reinforcement plate 1 is welded between the side wall outer panel 4 and the inner panel 5 of the center column, and the center column reinforcement plate 1 is located in the cavity. The pillar reinforcement plate 1 is prov...

Abstract

The invention discloses an automotive body center post with a strengthening structure, which comprises a side wall outer plate, a center post strengthening plate and a center post inner plate that are sequentially welded, wherein a safety belt fixing and strengthening plate and a safety belt nut plate are sequentially welded on the center post strengthening plate and are formed into a cavity section after welded through rolled edge laps at two sides; the safety belt fixing and strengthening plate is welded in a groove at the upper half part of the center post strengthening plate, the safety belt nut plate is welded and covered from the middle to the upper part of the safety belt fixing and strengthening plate, and a safety belt installing screw hole is arranged on the safety belt nut plate. The invention greatly strengthens the strength and the rigidity of the upper half part of the automotive body center post; the middle upper part of the center post is not easy to deform in collision at sides and enables the impact force to transmit to other energy absorbing parts of an automotive body, thereby ensuring that the impact force is dispersed and reduced and effectively protecting the head and the shoulder of the passenger at the front row.

Description

technical field [0001] The invention relates to an automobile body structure, in particular to a center pillar of an automobile body with a reinforced structure. Background technique [0002] The body of a general car has three pillars, which are the front pillar (A pillar), the middle pillar (B pillar), and the rear pillar (C pillar) from front to back. Supporting the roof cover also bears the supporting force of the front and rear doors, so the center pillar must have a certain strength and rigidity, and at the same time, some additional parts, such as front seat belts, must be installed on the center pillar. The existing center pillar generally includes side wall outer panels, center pillar reinforcing plates and center pillar inner plates welded together in sequence, and a seat belt nut plate is welded on the side of the center pillar reinforcing plate close to the center pillar inner plate. The safety belt nut plate 3 is welded with a nut 3a to form a safety belt insta...
