Description

The invention relates to the field of transport engineering, namely to the design of the lower part of the sidewall of the car body.

The closest technical solution to the claimed design is the frame structure of the sidewall of the car "Priora" ("Catalog of parts and assembly units. Cars LADA PRIORA", Togliatti, OJSC NVP "ITC AVTO", 2002, M260, p. M24) containing the panel floor, floor sill connector, bottom plate, side panel and floor sill amplifier, made of elongated shape and passing along the floor sill. The disadvantage of this design is that the amplifier has a significant weight, and with a side impact it deforms with an angular break inside the cabin, which leads to a prolonged repair of the entire side wall of the body.

The task of the utility model is aimed at dispersing the shock load during a side impact while simultaneously increasing the rigidity of the floor threshold.

To solve this problem, a car side body design is proposed, containing rigidly interconnected floor threshold connector and bottom side panel lining to form a tunnel space, which are internally connected to the floor panel, and from the outside side panel and lower side panel the sidewall overlays are the floor threshold walls, which are rigidly connected to the floor threshold connector by welding and mismatched along the floor threshold connector with the gap rum and lower plate sidewall.

Comparison of the claimed technical solution with the level of technology for scientific, technical and patent documentation on the priority date in the main and adjacent headings shows that the set of essential features of the claimed solution was not known - therefore, it meets the condition of patentability "novelty."

The proposed technical solution is industrially applicable, because can be manufactured industrially, workable, workable reproducibly, therefore, meets the condition of patentability "industrial applicability".

The essence of the technical solution is illustrated in the drawings.

FIG. 5 - view of the threshold of the floor with partitions in a perspective view.

The sidewall design of the car body in the area of the floor threshold of the opening of the front and rear doors includes a connector (1) of the floor bracket with a vertical shape with vertical longitudinal flanges (2) on the top and bottom on the end parts and the bottom cover (3) of the sidewall of almost the same shape, but with a shaped profile, and also with vertical longitudinal flanges (4) above and below on the end parts. The connector (1) of the floor sill and the bottom cover (3) of the sidewall are welded to each other by means of these flanges (2, 4) to form a tunnel space. Inside the tunnel space there are four partitions (5) floor thresholds, which are metal plates with a strength class of 300 MPa, with two partitions located in the front door, one in the rack area, and the fourth in the back door. The partitions are arranged transversely in the tunneling space and have bent flanges (6) on the rear portions of the partitions, with the help of which the partitions are welded to the floor threshold connector (1). In the center of the surface of the partitions (5) there are round holes (7) with a frame in the form of a protruding shoulder and designed to enhance the rigidity of the partitions (5). The front sections of the partitions repeat the profile of the bottom lining (3) of the sidewall and are set so that between them, that is, between the partitions and the bottom sidewall lining, a gap (8) is formed to distribute and reduce the deformation upon impact. A sidewall panel (9) is installed on the outside of the bottom lining (3) of the sidewall, which has a gap with the bottom sidewall lining and is a specific detail. The side panel (8) also has vertical longitudinal flanges (10) and is welded to the flanges (2, 4) of the bottom lining (3) of the side wall and the connector (1) of the floor sill. On the inside of the sidewall of the body, the connector (1) of the floor threshold is welded to the panel (11) of the floor of the body.

With a side impact, the sidewall panel (9) and the bottom lining (3) are deformed, choosing a gap, and partitions enter the work, dispersing and delaying a side impact. This solution allows to increase the safety of the body up to the level of EuroNCAP 2016.
