Upper reinforcing assembly for vehicle body B pillar

Abstract

The invention discloses an upper reinforcing assembly for a vehicle body B pillar. The upper reinforcing assembly comprises B pillar inner plates, top beams, B pillar connecting plates, upper edge beam inner plates and A pillar upper reinforcing plates; the side edge parts of the upper edge beam inner plates transversely extend to be fixed to the inner sides of the upper end parts of the B pillarinner plates, and the lower end parts of the B pillar connecting plates are fixed to the outer sides of the upper end parts of the corresponding B pillar inner plates; and inward-protruded protrusionparts are arranged in the middles of the B pillar connecting plates, and closed cavity structures are defined by the outer surfaces of the inner sides of the protrusion parts, the outer surfaces of the corresponding upper edge beam inner plates, the outer surfaces of the corresponding A pillar upper reinforcing plates and the outer surfaces of the corresponding top beams. According to the upper reinforcing assembly for the vehicle body B pillar, the problem that during side impact, loads are transmitted to the upper end of a B pillar assembly and then are unsmooth on a top beam path is effectively solved, the smoothness of the load transmitting path is ensured, the cavity structures are conducive to dispersion of the loads, and the situations that the vehicle body deformation is large dueto stress concentration, consequently deformation of upper edge beam areas of side doors of a vehicle body is large, the vehicle doors are difficult to open, and rescue of personnel in a vehicle is influenced are avoided.

Description

technical field [0001] The invention relates to a reinforcement assembly connected with a B-pillar of a vehicle body, in particular to an upper reinforcement assembly of a B-pillar of a vehicle body which strengthens the connection strength of the upper part of the B-pillar. Background technique [0002] The B-pillar structure of the body plays a key role in the torsional rigidity and collision safety of the body, especially the safety of side collisions. In the torsional condition of the body, the B-pillar structure affects the deformation of the body. The collision plays a role in reasonably absorbing the collision energy and protecting the safety of the occupants. The traditional B-pillar structure has the following problems: [0003] 1. If figure 1 and figure 2 As shown, the end of the traditional structure top beam 1' is fixed on the upper side sill inner panel 2', the upper end of the B-pillar inner panel 3' and the end of the top beam 1' are misaligned, and the to...
