Description
Technical Field
The invention relates to the technical field of automobile manufacturing, in particular to a doorsill supporting plate for improving the side collision performance of an automobile.
Background
The side collision is a collision detection item specified in mandatory regulations of GB20071 side collision passenger protection, and is also a collision item of the C-NCAP (collision-avoidance-network-component-code) of the star-level collision in the industry. The conventional threshold structure can meet the national mandatory regulations, but a more practical structure is required to be designed in a targeted manner to meet the five-star requirement in the C-NCAP collision. The existing threshold connection has various forms, some supporting plates have complex structures and heavy weight, and some supporting plates have small structures and cannot meet the requirement of five stars. The invention combines CAE analysis to develop a doorsill supporting plate structure with a brand new structure, can realize the generalization of parts, reduce the weight of the parts and the cost, and simultaneously can improve the side collision performance, prevent the doorsill from overturning and enable a vehicle to meet the five-star collision requirement.
Disclosure of Invention
The invention aims to solve the technical problem of providing a material frame of a threshold supporting plate assembly for improving the side collision performance, which can solve the problems that the existing supporting plate has a complex structure, is too heavy and cannot be used universally, or the existing supporting plate has a too small structure and cannot meet the five-star requirement in C-NCAP collision.
In order to solve the problems, the technical scheme of the invention is as follows: the threshold supporting plate for improving the side collision performance comprises an automobile floor, wherein a threshold inner plate is arranged at the edge of the automobile floor, and is welded with the automobile floor, a seat front cross beam and a seat rear cross beam on the automobile floor and then welded with a threshold outer plate; threshold cavity that threshold inner panel and threshold planking constitute, its characterized in that: a U-shaped first supporting plate and a U-shaped second supporting plate are arranged in the doorsill cavity, the first supporting plate is welded on the doorsill outer plate, and the second supporting plate is welded on the doorsill inner plate; the first supporting plate and the second supporting plate are aligned with the front seat beam and the rear seat beam, and the first supporting plate and the second supporting plate are aligned to form a back-to-back structure; and a gap for inserting the B column inner plate is reserved between the first supporting plate and the second supporting plate.
In the above technical solution, a more specific solution is: the first supporting plate and the second supporting plate are both U-shaped components formed by bending thin plates.
Further: the B column inner plate is inserted into a gap between the first supporting plate and the second supporting plate which are opposite to the rear cross beam of the seat.
Due to the adoption of the technical scheme, the invention has the following beneficial effects:
1. the supporting plate mainly comprises 2U-shaped parts, namely a first supporting plate and a second supporting plate, wherein the first supporting plate and the second supporting plate are respectively welded on a threshold outer plate and a threshold inner plate to form a back-to-back butt joint structure; the structure is used in bilateral symmetry, can be universal, and can be freely moved and placed in the threshold cavity according to CAE analysis requirements. The front seat transverse front beam and the front seat rear beam are usually arranged and centered. If the B-pillar inner plate is not aligned with the front row seat beam, a group of supporting plate structures can be added to the threshold inner plate at the position of the B-pillar inner plate.
2. The supporting plate has a simple structure, can effectively transmit side collision force when side collision occurs, prevents the threshold from overturning, reduces the bearing ratio of the front row seat beam by 30 percent, improves the side collision performance and effectively protects the safety of passengers.
3. The supporting plate has the advantages of simple structure, convenient process implementation and high part universalization, and can be freely added and reduced in the cavity of the threshold according to the CAE analysis requirement, so that the structure in the cavity of the threshold is prevented from being complicated.
4. The supporting plate structure has light weight and low cost, and the back-to-back structural form can effectively prevent the threshold from overturning, reduce the bearing rate of the front row seat beam, improve the side collision performance and protect passengers.
