Description

Body-in-white anti-submersion beam structure

technical field

The utility model relates to automobile components, in particular to a crossbeam for installing rear seats.

Background technique

With the rapid development of the automobile industry, the frequent occurrence of automobile safety accidents poses a serious threat to human life and property. How to reduce the injury of the occupants in automobile collision has also become a more and more important issue. If the height of the rear seat cushion is not enough or too flat, it is easy to slide forward during a collision, causing secondary injury to the occupant.

In order to avoid the secondary injury of the occupant after the collision, the anti-submersion design of the rear seat of the car is becoming more and more common. There are three main methods for the anti-submersion design of the rear seats, one is to directly raise the rear floor and install the seat cushion directly on the rear floor; the other is to use a beam welded on the rear floor to raise the installation surface of the seat cushion The third way is to design the anti-submersion mechanism on the seat cushion body. The cost of the first way is lower, but it is difficult to form the rear floor. The second method is widely used, but it is not conducive to the utilization of multiple models and the expansion of platforms; the third method is more expensive.

Utility model content

In view of the deficiencies in the background technology, the purpose of this utility model is to provide a body-in-white anti-submersion crossbeam that can reduce the cost without affecting the welding process level of the original model and reliable anti-submersion of the rear seats. structure.

In order to achieve the above purpose, the anti-submersion beam structure of the body-in-white designed by the utility model is characterized in that: it includes a horizontal part body and two connecting brackets; the two sides of the horizontal part body are connected with the first inclined part and the second inclined The end of the horizontal part is connected, and the horizontal part body, the first inclined part and the second inclined part form an opening with a gap gradually increasing; one end of the first inclined part is connected with the horizontal part body, and the other end is spaced apart There are a plurality of first flanges, each of which is provided with a first through hole; the second inclined part is provided with a plurality of second through holes at intervals; the two connecting brackets are arranged on the The second flange on the connecting bracket is welded to both ends of the horizontal part body, and the third flange is welded to the first inclined part; a plurality of cushion flip brackets are welded at intervals on the top surface of the horizontal part body .

Further, a plurality of beam reinforcing plates are provided at intervals in the opening. In this way, it plays the role of strengthening and supporting.

Further, the connection bracket includes a horizontal plate, and two adjacent sides of the horizontal plate are respectively provided with a first vertical plate and a second vertical plate connected to each other; the side wall of the first vertical plate is provided with a second vertical plate. Two flanges, the second flange is parallel to the second vertical plate; the second vertical plate is provided with a third flange, and the third flange is parallel to the horizontal plate.

Furthermore, a connecting vertical plate is provided on one side of the horizontal plate adjacent to the first vertical plate; the connecting vertical plate is set opposite to the second vertical plate, and the connecting vertical plate and the first vertical plate The plates are located on both sides of the horizontal plate; one end of the connecting vertical plate is connected to the horizontal plate, and the other end is provided with a third through hole.

The beneficial effects of the utility model are: while reducing the cost, a reliable rear seat anti-submersion installation crossbeam structure is provided, and the welding process level of the original vehicle can not be affected. Without changing the structure of the original model, it is installed on the body with bolts, achieving a detachable installation. The utility model not only supports the seat cushions of the rear seats, but also the connecting brackets welded on both sides of the crossbeam can be used to fix the interior trim guards, which avoids the situation that the two sides of the seat cushions are suspended, and perfectly completes the seat cushion skeleton and the floor. excessive. At the same time, a seat cushion rotating bracket is welded on the crossbeam, realizing the function of seat cushion turning over.
