Description

A kind of sports car B post side impact additional strengthening

Technical field

The utility model relates to a kind of two place's sheet metal structurals of automobile side, particularly discloses a kind of sports car B post side impact additional strengthening.

Background technology

Current domestic automobile product is more and more, and competition is growing more intense, and in order to occupy the domestic and international market, each main engine plants more and more payes attention to the safety of vehicle newly developed.Simultaneously, the safety problem of automobile also more and more is subjected to customer's attention, as long as but a lot of customer think have safety air bag, security configuration such as ABS, the safety of automobile has just had assurance.Quite different in fact, for the safety of automobile, body structure is only the most basic, most important.The B-pillar structure design that plays a crucial role in the side collision is again the most important thing.Four general common three-box cars are owing to there is the support of package shelf, and the B post of ordinary construction just can satisfy the collision requirement, but has following two problems for the new model of two hatchback sport cars:

1. the car door size is bigger, and the most of external force during side collision will drop on the B post like this;

2. this car does not have the cross-tie of package shelf, and this function has also dropped in the design of B post, so this car requires just higher to B post safety performance.

Summary of the invention

The purpose of this utility model is to solve the defective that exists in the prior art, and the sports car B post side impact additional strengthening that a kind of safety factor height, carriage body construction are strengthened, living space is big is provided.

The utility model is achieved in that a kind of sports car B post side impact additional strengthening, comprise side-wall outer-plate, side-wall inner-plate, the B post that the B column reinforcement plate is combined into, described B post lower end and body contact, vehicle body is fixed on the chassis, the side-wall inner-plate top is connected with roof panel cross member, it is characterized in that: the medial surface at described B post lower end and body contact place is provided with the gusset side brace, described gusset side brace upper end and side-wall inner-plate handing-over, the handing-over angle is β, described β angular region: 30 °≤β≤60 °, gusset side brace lower end and body platform handing-over, the handing-over angle is α, described α angular region: 30 °≤α≤60 °.

Described side-wall inner-plate and roof panel cross member form the osed top cavity at roof panel cross member and B capital end junction, become the structure that strengthens the vehicle body resistance to bending.

The β angle of cut of the gusset side brace of described B post is 45 °, and the α angle of cut is 45 °.

The beneficial effects of the utility model are: when the sports car side runs into collision, the energy that the B post is born reduces, the amount of the crumple distortion of B post reduces, so passenger's living space will increase, the chances of survival of occupant in the car just can improve greatly simultaneously, and the star rating achievement of the side collision of sports car also can improve simultaneously.

The specific embodiment

According to Fig. 2, Fig. 3, Fig. 5, Fig. 7, the utility model comprises side-wall outer-plate, side-wall inner-plate 1, the B post that B column reinforcement plate etc. is combined into, described B post lower end and body contact, vehicle body is fixed on the chassis, side-wall inner-plate 1 top is connected with roof panel cross member 3, the medial surface at described side-wall inner-plate 1 lower end and body contact place is provided with gusset side brace 2, described gusset side brace 2 upper ends and side-wall inner-plate 1 handing-over, the handing-over angle is β, the β angular region is 30 °≤β≤60 °, the handing-over of gusset side brace 2 lower ends and body platform, the handing-over angle is α, the scope at α angle is 30 °≤α≤60 °.Described side-wall inner-plate 1 forms the osed top cavity with roof panel cross member 3 in roof panel cross member 3 and B capital end junction, becomes the structure that strengthens the vehicle body resistance to bending.The β angle of cut of described gusset side brace 2 is 45 °, and the α angle of cut is 45 °.

According to arrow shown in Fig. 1 is the power transmission direction of vehicle body when being collided, and as can be seen, the external force part during side collision is offset by the crumple of vehicle body, and another part will lean on the rigidity of vehicle body self that it is subjected to displacement in the direction of external force and offset.Among gusset side brace 2, Fig. 3 and Fig. 7 among Fig. 2 the roof panel cross member 3 of special construction and side-wall inner-plate 1 be exactly the utility model in order to strengthen the vehicle body integral rigidity, resist vehicular sideview collision, guarantee living space in passenger's the car and the Creative Design of carrying out.Below in conjunction with Fig. 1～Fig. 7 structure function principle of the present utility model is done further to analyze:

One. the gusset side brace

Analysis chart 4, Fig. 5, can only eliminate the energy of collision as can be seen during the prior art constructions side collision by power transmission up and down, can cause the crumple distortion of B post direction in car big like this, occupied interior space, passenger's living space will significantly reduce like this, has reduced the probability of surviving of the occupant in the car.And structure of the present utility model is when side collision, because the gusset side brace 2 of innovative design has been arranged, the energy of the collision on the B post is divided into three parts and passes to vehicle body, the energy born of B post has reduced like this, the crumple deflection of B post will reduce, so passenger's living space will increase, the probability of surviving of the occupant in the car also can improve greatly simultaneously.Can better meet the collision rules, improve the side collision star rating.Gusset side brace 2 and horizontal direction angulation α among Fig. 5, with the size of vertical direction angulation β the support and the power transmission effect of gusset side brace 2 there is certain influence, therefore support and the power transmission effect for guaranteeing, it is 30 °≤α≤60 ° that the scope of angle also has requirement, 30 °≤β≤60 °, wherein when α=45 °, β=45 °, effect the best of side brace.

Two. the roof panel cross member of special construction and the side-wall inner-plate of special construction form special form of fracture at B post place.

Analysis chart 6 and Fig. 7, prior art covering for roofs crossbeam 3 does not form closed cavity with side-wall inner-plate 1 in the junction as can be seen, lap-joint at roof panel cross member 3 and side-wall inner-plate 1 is the simple superposition of sheet material, resistance to bending a little less than, the transfer of energy of collision side can not be arrived an other sidecar body, can only rely on the crumple of colliding side B post to be out of shape and absorb energy, can cause the crumple distortion of B post direction in car big like this, occupied interior space, passenger's living space will significantly reduce like this, has reduced the probability of surviving of the occupant in the car.And the utility model is in car roof area, and the high strength roof panel cross member 3 and the side-wall inner-plate 1 of brand-new design have formed the osed top cavity in the junction, strengthened the resistance to bending of vehicle body, makes vehicle body be not easy the crumple distortion.When collision, identical crumple deflection can absorb more energy, and energy can directly be sent to the vehicle body that is delivered to opposite side on the roof panel cross member 3 by side-wall inner-plate 4.The energy born of B post has reduced like this, and the crumple deflection of B post will reduce, so passenger's living space will increase, the probability of surviving of the occupant in the car also can improve greatly.The utility model also will better meet the collision rules like this, improves the side collision star rating.
