Abstract
The invention discloses a floor beam structure of an automobile. The floor beam structure comprises a floor body, wherein a central channel is formed in the middle of the floor body; side threshold assemblies which are symmetric with each other are arranged on two sides of the floor body; two floor upper longitudinal beams and two seat installation transverse beam assemblies, which are symmetric with each other, are arranged in the front of the floor body; the rear end of each floor upper longitudinal beam is vertically connected with the middle of each seat installation transverse beam assembly; and two ends of each seat installation transverse beam assembly are respectively connected with the central channel and the side threshold assemblies. The floor beam structure of the automobile is characterized in that: two reinforcing plates are respectively connected with the two floor upper longitudinal beams and the two side threshold assemblies to form two symmetric triangular structures. The floor upper longitudinal beams, the side threshold assemblies, the central channel and the floor body are organically combined together through the reinforcing plates to form the triangular structures in bilateral symmetry, so that side collision acting forces can be effectively scattered and transferred, and the stiffness of a seat installation part is improved.
Description
Technical field
The present invention relates to automobile body components, be specifically related to a kind of automotive floor panel girder construction.
Background technology
Constantly perfect along with developing of automobile industry and laws and regulations, increasingly high to the security requirement of automobile.How when crashing, to protect occupant's safety to greatest extent, become the important content of automobile design.For the automobile design personnel, under limited cost and spatial control, adopt the actv. body structure to go to promote the safety of automobile, be necessary.The floor bearer structure of self-supporting body is occupied very consequence to the contribution of the strength and stiffness of whole vehicle body, the effect of especially when vehicle body collides, play dispersion, transmitting tampering action power, absorbing impact energy.Therefore, the floor bearer structure design of self-supporting body seems particularly important.In order to satisfy vehicle body cae analysis, Collision test etc., all be to realize usually through increasing reinforcement or substituting general steel plate with high tensile steel plate, will cause the increase of cost like this.And adopt actv. version, and can under the prerequisite that does not increase cost, arrive designing requirement, promote bus body strength and rigidity.
Summary of the invention
The objective of the invention is to propose a kind of automotive floor panel girder construction, the side impact application force can effectively disperseed and transmit to this structure, and can improve the rigidity at chair mounted position.
A kind of automotive floor panel girder construction of the present invention; Comprise floor body; Be provided with centre gangway at the middle part of floor body, both sides are respectively equipped with symmetrical side door sill assembly; Be provided with longeron and chair mounted crossbeam assembly on the symmetrical floor in the front portion of floor body, on two floors the rear end of longeron respectively with vertical connection of middle part of two chair mounted crossbeam assemblies, the two ends of two chair mounted crossbeam assemblies are connected with side door sill assembly with centre gangway respectively; It is characterized in that: two brace panels respectively with two floors on longeron be connected with both sides threshold assembly, form two symmetrical triangular shape structures.This triangular structure can effectively be disperseed tampering action power, the absorbing impact energy, thus effectively reduce crew module's degree of tortuosity, played protection occupant's effect.
Longeron is connected on the described a kind of automotive floor panel girder construction, first flange of its said brace panel one end and floor, and second flange of the other end is connected with side door sill assembly; The 3rd flange of said brace panel one side and the 4th flange of opposite side are connected with floor body respectively.
This floor bearer structure left-right symmetric.The connection mode of (centre gangway, side door sill assembly, floor body) is the resistance welding mode between each parts.Through the said structure form, one side has promoted the intensity of chair mounted crossbeam assembly, has been equivalent to effectively promote the intensity at seat arrangement position, when collision, effectively disperses on the other hand and transmission tampering action power.
Beneficial effect of the present invention: owing to longeron, side door sill assembly, centre gangway and floor body on the floor are organically combined through brace panel; Form symmetrical triangular structure; Thereby can disperse effectively and transmit the side impact application force, and improve the rigidity at chair mounted position.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is longeron on the floor, brace panel and chair mounted crossbeam assembly bonded assembly scheme drawing;
Fig. 3 is the structural representation of brace panel.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
Referring to Fig. 1, Fig. 2 and a kind of automotive floor panel girder construction shown in Figure 3; Comprise floor body 1; Be provided with centre gangway 2 at the middle part of floor body, both sides are respectively equipped with symmetrical side door sill assembly 3; Be provided with longeron 4 and chair mounted crossbeam assembly 6 on the symmetrical floor in the front portion of floor body; On two floors the rear end of longeron 4 respectively with vertical connection of middle part of two chair mounted crossbeam assemblies 6, the two ends of two chair mounted crossbeam assemblies 6 are connected with side door sill assembly 3 with centre gangway 2 respectively; Two brace panels 5 respectively with two floors on longeron 4 be connected with both sides threshold assembly 3, form two symmetrical triangular shape structures.
Further, longeron 4 is connected on first flange 7,8 of said brace panel 5 one ends and the floor, and second flange 11 of the other end is connected with side door sill assembly 3; The 3rd flange 9 of said brace panel 5 one sides and the 4th flange 10 of opposite side are connected with floor body 1 respectively.
When central collision takes place when; Tampering action power passes to longeron on the floor through front deck; Application force is reinforced plate and disperses a part to side door sill assembly in side direction through on the floor during longeron, has reduced the load of chair mounted crossbeam assembly; Thereby effectively reduce the degree of tortuosity of operator's compartment, protected occupant safety.
When side impact took place, side door sill assembly bore most of tampering action power, and in this structure, except chair mounted crossbeam assembly transmits a part of tampering action power to centre gangway, brace panel disperses a part of tampering action power longeron to the floor in side direction simultaneously.
