Abstract
The invention discloses a collision energy absorption structure of an automobile. The structure comprises a front longitudinal beam, a side doorsill and a floor central passage, wherein the middle part of the front longitudinal beam is connected with the front end of the side doorsill through an outer connecting plate; both the front longitudinal beam and the side doorsill are symmetrically arranged on the two sides of the floor central passage; beam type structures with U-shaped cross sections are formed on the two sides of the floor central passage; and the middle part of the front longitudinal beam is connected with the floor central passage through an inner connecting plate. Through the collision energy absorption structure of the automobile, impulsive load produced by collision from a front face or a side face can be effectively and uniformly dispersed and absorbed, so that the bending rigidity and the torsional rigidity of the entire vehicle body are greatly enhanced.
Description
Technical field
The present invention relates to the body structure of automobile, be specifically related to a kind of collision energy-absorbing structure of automobile.
Background technology
In the prior art, longeron as one independently parts be welded on the vehicle body, it mainly acts on is to bear vehicle body load and when collision happens, absorb front side member or impact load that the threshold transmission comes.When the head-on crash load ratio is big, because utilizable energy-absorbing parts have only longeron and threshold, can't suitably disperse at all and absorb impact load, the impact load that causes the part to receive is bigger, thereby the occupant is come to harm.And, when side collision takes place when and since the structural limitations of existing floor centre gangway its absorption to energy, thereby make the floor centre gangway that bigger distortion take place easily, also can cause the occupant to come to harm.
Summary of the invention
The collision energy-absorbing structure that the purpose of this invention is to provide a kind of automobile is to strengthen the ability of auto body absorbing impact impact energy.
The collision energy-absorbing structure of automobile according to the invention comprises front side member, side door sill and floor centre gangway; The middle part of front side member is connected with side door sill front end through outer side connecting plate; Front side member and side door sill all are arranged symmetrically in the both sides of floor centre gangway; Centre gangway both sides, said floor are the girder structure that cross-sectional plane takes the shape of the letter U, and the middle part of front side member is connected with the floor centre gangway through interior side connecting plate.
As preferably, said in the cross-sectional plane of side connecting plate take the shape of the letter U, its front end with centre gangway both sides, floor girder structure welds.
When automobile received the impact load of head-on crash generation, front side member disperseed impact load through three approach: one, front side member leading portion to front side member back segment; Two, the front side member leading portion is through outer side connecting plate to side door sill; Three, the front side member leading portion through interior side connecting plate to floor centre gangway.When receiving the impact load of side collision generation,, floor centre gangway bending stiffness and torsional stiffness have been improved because centre gangway both sides, floor are the girder structure that cross-sectional plane takes the shape of the letter U.
The collision energy-absorbing structure of automobile according to the invention is owing to have this kind structure; Can the impact energy of auto against be passed to the floor through three approach; Impact load is distributed on the different parts on floor equably; Thereby avoided the excessive and body distortion that causes of local assault, improved the ability of auto body absorbing impact impact energy largely.In whole collision energy-absorbing structure; Comprise side door sill, front side member and floor centre gangway with the floor overlap joint; These parts are girder structure, add the U-shaped girder structure of centre gangway both sides, floor, so can greatly strengthen the bending stiffness and the torsional stiffness of whole body in white; Thereby improve the travelling comfort of car load, effectively reduce the generation of abnormal sound.
Description of drawings
Fig. 1 is that the axle of the collision energy-absorbing structure of automobile according to the invention is surveyed scheme drawing;
Fig. 2 is the schematic top plan view of the collision energy-absorbing structure of this automobile;
Fig. 3 is that the axle of floor centre gangway is surveyed scheme drawing;
Fig. 4 is vertical view of floor centre gangway.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further:
Extremely shown in Figure 4 like Fig. 1; The collision energy-absorbing structure of this automobile is made up of left and right sides front side member 2, left and right sides threshold 4 and a floor centre gangway 6; The middle part of left and right sides front side member 2 is connected with left and right sides threshold 4 front ends through outer side connecting plate 3 respectively; Left and right sides front side member 2 and left and right sides threshold 4 are arranged symmetrically in the both sides of floor centre gangway 6, and the middle part of left and right sides front side member 2 is connected with floor centre gangway 6 through interior side connecting plate 1.Centre gangway 6 both sides in floor are that the cross-sectional plane of 5, two interior side connecting plates 1 of girder structure of all taking the shape of the letter U of cross-sectional plane all takes the shape of the letter U, and two interior side connecting plates 1 are welded to connect with the front end of floor centre gangway 6 both sides girder structures 5 respectively.
