Abstract

The utility model relates to a central pillar assembly of a compact car, comprising a side round outer covering, a central pillar inner covering, a central pillar reinforcement, a central pillar hinge installation reinforcement and a central pillar lower reinforcement, wherein the side round outer covering and the cross section of the central pillar reinforcement are in U-shaped structure in the same direction, the side round outer covering is coated on the central pillar reinforcement, the side round outer covering and the central pillar reinforcement are in butt-welding with the central pillar inner covering to form a central pillar cavity between the central pillar reinforcement and the central pillar inner covering for a bigger deformation space, thereby the energy in the touching process cam be absorbed well, the intrusion amount of the central pillar can be reduced and the damage value to the occupants is reduced. The hinge installation reinforcement is welded on the inner side of the central pillar reinforcement and the central pillar lower reinforcement is welded on the inner side of the hinge installation reinforcement to reinforce the integral structure of the central pillar, so that the energy in the touching process is transferred from the central pillar to a doorsill girder and a top cap cross girder to form a complete energy transmission path, thus guaranteeing the safety of the occupants.

Description

A kind of intermediate-size car central post assembly

Technical field

The utility model belongs to the automotive body structure technical field, is specifically related to a kind of intermediate-size car central post structure.

Background technology

The design of car central post section has directly determined the safety of car load side impact.At present, each vehicle central post section has nothing in common with each other, and cost height, section size, weight, secure context difference are very big.Referring to Fig. 1, general many employing U font central post reinforcements 3 of vehicle and straight central post inside panel 2 butt joint weldings in the past form cavity, when satisfying side collision, and endergonic requirement.Central post exterior skin 1 is a U-shaped also, is welded on outside the central post reinforcement 3.But the cavity that this structure forms is limited, can not effectively absorb the energy in the collision, and central post intensity is low, and interior of body is invaded in the distortion that fractures in the middle of taking place easily, causes occupant injury.

Summary of the invention

The utility model just is to provide a kind of intermediate-size car central post assembly; realize the requirement of strength of vehicle body by the structure that changes between central post reinforcement and the central post inside panel to the central post place; satisfy corresponding national side impact rules, improve the vehicle body crash survivability, the protection occupant safety.

A kind of intermediate-size car central post assembly, comprise gusset exterior skin, central post inside panel and central post reinforcement, described gusset exterior skin and central post reinforcement cross section are equidirectional U-shaped structure, the gusset exterior skin is coated on outside the central post reinforcement, they and the butt welding of central post inside panel, between central post reinforcement and central post inside panel, form the central post cavity, medial surface at the central post reinforcement also is welded with hinge installation reinforcement, and the cross section that hinge is installed reinforcement is and the equidirectional U-shaped in central post reinforcement cross section.

Be welded with reinforcement under the central post in the bottom of described central post and at the medial surface that hinge is installed reinforcement.The cross section of described central post inside panel is a U-shaped, and direction is opposite with the cross section U-shaped of central post reinforcement, and the central post cavity that both U-shapeds surround formation is nearly square.

In this structure, increased hinge in the side of central post reinforcement reinforcement hinge installation reinforcement has been installed, strengthened the integral structure of central post.Further reinforcement under the central post that increases in the bottom, the centering column lower end has good booster action, and actv. reduces the intrusion amount of central post lower end.In addition, the central post inside panel also is designed to U-shaped, formed the bigger tetragonal central post cavity in space with central post reinforcement assembly welding, increase the section cavity size at central post place as much as possible, thereby can provide bigger deformation space, can well absorb the impulsive force of side collision by the distortion of central post cavity self, simultaneously impact force is passed to sill strip by the central post structure, the impulsive force that collision is produced can be very fast each position that is delivered to vehicle body, reduce crew module's deflection, reduce the intrusion amount of local collision.

Description of drawings

Fig. 1 is existing automobile central post section structure scheme drawing;

Fig. 2 is a central post assembly exploded view of the present utility model;

Fig. 3 is this central post assembly section structure scheme drawing;

Wherein, 1-gusset exterior skin, 2-central post inside panel, 3-central post reinforcement; 4-central post hinge is installed reinforcement, reinforcement under the 5-central post;

The specific embodiment

Referring to Fig. 2 and Fig. 3, this intermediate-size car central post assembly comprises reinforcement 5 under gusset exterior skin 1, central post inside panel 2, central post reinforcement 3, central post hinge installation reinforcement 4 and the central post.Wherein the cross section of gusset exterior skin 1 and central post reinforcement 3 is equidirectional U-shaped structure, and gusset exterior skin 1 is coated on outside the central post reinforcement 3.The cross section of central post inside panel 2 also is a U-shaped, and direction is opposite with the cross section U-shaped of central post reinforcement, and it and gusset exterior skin 1 and 3 butt welding of central post reinforcement form nearly tetragonal central post cavity between them.The medial surface of central post reinforcement 3 is welded with hinge reinforcement 4 is installed, the cross section that hinge is installed reinforcement 4 also with the equidirectional U-shaped in central post reinforcement 3 cross sections.Also be welded with reinforcement 5 under the central post in the bottom of central post and at the medial surface that hinge is installed reinforcement 4.

This central post assembly is to have earlier to be installed by the hinge of the central post reinforcement 3 of U type, U type that reinforcement 5 should form the central post cavity structure with the gusset exterior skin 1 of U type and central post inside panel 2 butt welding of U type by the welding assembly then again by being welded into a welding assembly under reinforcement 2 and the central post.With respect to plate in the past central post inside panel 2, the central post inside panel 2 of U type can provide bigger deformation space, thereby the energy in can better the absorbing side impact process reduces the intrusion amount of central post, reduces occupant's injury values.Compare with central post structure in the past, the utility model has increased the central post hinge newly reinforcement 5 under reinforcement 4, the central post has been installed, strengthened the integral structure of central post, the energy that is beneficial in the side impact process is delivered on sill strip and the roof panel cross member by central post, constitute complete energy-transmission channel, guarantee occupant safety.
