Description

Door structure and vehicle with anticollision roof beam linking bridge

Technical Field

The utility model relates to an automobile body design field. More specifically, the present invention relates to a door structure with an impact beam attachment bracket, and to a vehicle including such a door structure.

Background

With the increasing amount of domestic vehicles, the number of vehicle collision traffic accidents is increased, and among numerous collision accidents, side collision is an accident form with high occurrence frequency and great damage. To reduce occupant injury during a side impact, a safe and effective passive safety device is needed. The functional design of reinforcing the door structure against a side collision has been one of the important items for evaluating the safety performance of a vehicle. Impact beams are important guards in vehicle door construction that can be used to resist side impacts. When a vehicle is in a side collision, the anti-collision beam absorbs energy generated by the vehicle collision through deformation generated by the anti-collision beam, and can reduce the invasion amount and the invasion speed of foreign matters invading a door in the side collision, thereby achieving the purpose of reducing the injury of vehicle passengers. The impact beam is generally made of a high-strength low-carbon steel material, and is generally a rectangular section beam or an i-shaped section beam.

In other words, the upper end of the upper linking bracket 4 is fixedly connected to the door inner panel 1 at a substantially middle position (i.e., a waist position), the lower end is fixedly connected to the middle portion of the impact beam 3, the upper end of the lower linking bracket 5 is fixedly connected to the middle portion of the impact beam 3, and the lower end is fixedly connected to the bottom position of the door inner panel 1, i.e., the upper linking bracket 4 and the lower linking bracket 5 are disposed at substantially middle positions in the front-rear direction of the upper and lower trapezoids formed by the impact beam 3 and the door inner panel 1, so as to improve the strength and rigidity of the door structure to the maximum extent. In this embodiment, the door structure further includes a waist reinforcing plate 6 fixedly attached to the waist portion of the door inner panel 1, for example, by welding or the like, and the upper end of the upper attaching bracket 4 is in fact fixedly attached to the waist reinforcing plate 6 to form a fixed connection with the door inner panel 1. The upper and/or

lower attachment brackets

4, 5 can be connected to the door inner panel 1 (or the lumbar reinforcement panel 6) and the impact beam 3, for example, by welding or bolting. Preferably, the upper connecting bracket 4 and/or the lower connecting bracket 5 are made of a common low carbon steel material, are formed by stamping, and may have a certain curvature to increase the connecting strength.

It should be understood, of course, that the illustrated arrangement of the impact beam attachment brackets is not limiting and that various changes may be made depending on the actual configuration of the door structure and the impact function requirements. For example, the upper connecting bracket 4 and/or the lower connecting bracket 5 may be arranged substantially perpendicular to the impact beam 3, or may be arranged to form an angle of significantly less than 90 ° with the impact beam 3. Furthermore, the upper connecting bracket 4 and the lower connecting bracket 5 can extend substantially in the same line, can also be offset parallel to one another or can form an angle of significantly less than 180 ° with one another. Furthermore, the number of the upper connecting brackets 4 and/or the lower connecting brackets 5 is not limited, and more than one upper connecting bracket 4 and/or lower connecting bracket 5 may be arranged according to actual requirements.

FIG. 4 is a perspective view of an upper attachment bracket of the vehicle door structure of FIG. 3, and FIG. 5 is a perspective view of a lower attachment bracket of the vehicle door structure of FIG. 3.
