Abstract

The utility model relates to a car front floor reinforcement structure which comprises a front seat lower beam, a first row seat left/right front supporter and a first row seat left/right rear supporter. The first row seat left/right front supporter and the first row seat left/right rear supporter are respectively welded at two ends of the front seat lower beam. The whole front floor reinforcement structure is shaped like the Chinese character 'gong' upside-down. In the utility model, the front seat lower beam is used as a work piece special for increasing the side impact strength of the car and the strength of the front floor, the two end surfaces of the work piece are close to the B column and simultaneously the whole work piece passes horizontally through the car body in an upside-down 'V'shape, moreover, the work piece is structured to have two trumpet-shaped portions, that is, the cross-sectional area of the work piece is increasing gradually from the middle to the end. Therefore, the work piece can bear large-area impact. The mount point of the seat is on the first row seat front/back supporter, facilitating the installation. Additionally, the first row seat front/back supporter is welded with the front seat lower beam and then welded on the front floor, thereby provide the reinforcement to the front floor.

Description

A kind of automobile front floor reinforcement structure

Technical field

The utility model belongs to car accessory technical field, is specifically related to the additional strengthening design to the car floor.

Background technology

Along with the fast development of auto trade, the requirement of every legislative control on safety is also more and more stricter, and with regard to side impact, a lot of cars all can not meet the demands well.Must there be enough intensity on the B-post and the floor of side impact test requirements document automobile, and by increasing reinforcement, perhaps use high tensile steel plate all can increase manufacturing cost.Existing a lot of seat cross sill is all in traditional body structure, the front-row seats cross sill is to be used as the support that seat is installed to use, its feature is flat and flat, be " one " font and traverse vehicle body, be simple linear pattern lateral arrangement structure, this structure is very little to the contribution of strengthening the vehicle body side collision strength.Effect only limits to install seat, and is little to strengthening the contribution of floor intensity and central post intensity.Therefore, design a kind of front floor reinforcement structure and seem important and urgent.

Summary of the invention

The purpose of this utility model is to provide a kind of seat can conveniently be installed at the defective of prior art existence, can strengthen the reinforcement structure of floor intensity and central post intensity again.

The technical solution of the utility model is as follows:

The automobile front floor reinforcement structure, it is made up of front-row seats cross sill, first row's seat left and right sides front frame and first row's seat left and right sides after poppet.Its front-row seats cross sill structurally slightly is down " V " font, and section is enlarged to two ends gradually by the centre, slightly become two horn-like; The two ends of front-row seats cross sill are welded first row's seat left and right sides front frame and first row's seat left and right sides after poppet respectively, and whole front floor reinforcement structure is " worker " font of putting upside down, and the central post of two close automobiles of end face lap-joint.

The effect of invention: the utility model is as the special part of strengthening vehicle body side collision strength and preceding floor intensity with the front-row seats cross sill, with the close automobile central post of its two end face lap-joints, make whole part shaped slightly when traversing vehicle body be down " V " font simultaneously, and with part design become two horn-like, be that the part cross-sectional area is expanded to two ends gradually by the centre, part just can bear the larger area impact like this.And the attachment point of seat is easy for installation on the forward and backward support of first row's seat.Simultaneously, be soldered to again on the preceding floor behind first row's forward and backward support of seat and the front-row seats cross sill weld together, preceding floor is had booster action again.

Fig. 2: the structural representation of front-row seats cross sill among Fig. 1;

Fig. 3: the location diagram of front floor reinforcement structure and automobile central post (only having shown central post on one side);

Fig. 4: the location diagram of plate behind front floor reinforcement structure and the preceding floor.

The specific embodiment

Referring to Fig. 1, the front floor reinforcement structure is made up of front-row seats cross sill 1, the left front support 2 of first row's seat, the left back support 3 of first row's seat, the right front support 4 of first row's seat, the right back support 5 of first row's seat.With first row the forward and backward support of seat (left side/right side) totally four be welded on respectively on the front-row seats cross sill 1, whole like this reinforcement structure has just formed " worker " word of putting upside down, then whole reinforcement structure is welded on the automobile front floor 7, see Fig. 4 and Fig. 3, with the close automobile central post 6 of its two end face lap-joints, just can play simultaneously as the effect of strengthening vehicle body side collision strength and preceding floor intensity.Wherein, the utility model has special design to the front-row seats cross sill, sees Fig. 2, and it structurally slightly is down " V " font, and section is enlarged to two ends gradually by the centre, slightly become two horn-like.

Claims

1. automobile front floor reinforcement structure, it is made up of front-row seats cross sill, first row's seat left and right sides front frame and first row's seat left and right sides after poppet; It is characterized in that: the front-row seats cross sill structurally slightly is down " V " font, and section is enlarged to two ends gradually by the centre, slightly become two horn-like; The two ends of front-row seats cross sill are welded first row's seat left and right sides front frame and first row's seat left and right sides after poppet respectively, and whole front floor reinforcement structure is " worker " font of putting upside down, and the central post of two close automobiles of end face lap-joint.
