Description
Technical Field
The utility model relates to an auto-parts field especially relates to a B post reinforcing plate suitable for new forms of energy motorcycle type.
Background
In recent years, with the upgrade of new domestic vehicle evaluation regulations, C-NCAP and C-IASI have been paid more attention by manufacturers and consumers. The side collision is taken as a working condition for the key investigation of the evaluation regulations of two new vehicles, and the requirement on the B column structure is higher and higher. Particularly, the American standard barrier in the C-IASI is higher in ground clearance and higher in damper rigidity compared with the C-NCAP, and the collision position is closer to the upper part of the automobile. Therefore, for cars, partial SUVs and MPVs, the B-pillar becomes the main bearing structure. Although each major manufacturer adopts a side door anti-collision structure with stronger and more uniform stress, the B column is used as a midstream baffle column and plays a key role in the side collision result. Especially for C-IASI B column breakage which reduces the rating requirement, more care is taken for the design of the side ensemble.
In recent years, the design of the side impact is gradually transited from 'hard resistance' to 'overall hard resistance and local deformation', namely, the B column is not designed to be hardly deformed, but a deformation area is designed at a part of the B column to absorb the side impact energy. Meanwhile, the rigidity of the whole door ring on the side surface is increased, and the whole door ring bears the impact energy on the side surface. Therefore, the invention of the B-pillar reinforcing plate suitable for new energy vehicle types is important.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a B post reinforcing plate suitable for new forms of energy motorcycle type, satisfying under the condition of side collision invasion volume and invasion speed, going to reduce as far as possible because the problem of increasing the side wall weight increase that too much B post reinforcing plate brought.
The utility model provides a technical scheme that its technical problem adopted is:
a B-pillar reinforcing plate suitable for a new energy vehicle type comprises a reinforcing plate body, wherein the reinforcing plate body is of a double-layer structure, a hot forming material is arranged on the outer side of the upper area of the reinforcing plate body, an auxiliary reinforcing plate made of a hot forming material is fixedly arranged on the inner side of the reinforcing plate body, and a double-phase steel material is arranged on the lower area of the reinforcing plate body;
the reinforcing plate body is provided with outer reinforcing ribs protruding towards the outside of the vehicle from top to bottom, and inner reinforcing ribs recessed towards the inside of the vehicle are arranged in the upper areas of the outer reinforcing ribs; the auxiliary reinforcing plate is attached to the concave-convex surface matched with the outer reinforcing rib and the inner reinforcing rib.
Further, the material thickness of the auxiliary reinforcing plate is 2.0 mm.
Further, the thickness of the material outside the upper area of the reinforcing plate body is 1.6 mm.
Further, the material thickness of the lower area of the reinforcing plate body is 1.6 mm.
Further, the upper and lower regions of the reinforcing plate body are fixedly connected by welding.
Furthermore, the auxiliary reinforcing plate is fixedly connected with the outer reinforcing rib through spot welding.
Furthermore, the widths of the lapping areas of the upper side, the lower side, the left side and the right side of the reinforcing plate body and the vehicle body are respectively 35-50 mm, 90-120 mm, 25-55 mm and 25-55 mm.
The utility model has the advantages that: the utility model relates to a B post reinforcing plate suitable for new forms of energy motorcycle type, B post adopt the mode of soft or hard subregion, guarantee that the side collision can the deformation position energy-absorbing, reduced the unpredictable deformation of other positions of B post; the upper part of the B column is reinforced, so that the whole B column is prevented from invading inwards, and the local invasion is avoided; the hot forming amount of the B-pillar reinforcing plate is reduced, and the problem of easy breakage caused by low integral elongation is avoided; the stress of the side door and the invasion amount of the side door are reduced, so that the damage to personnel in the side collision process is reduced. Thereby meeting the requirements of side collision deformation and integral rigidity.
The present invention will be described in more detail with reference to the accompanying drawings and examples.
