Abstract
Disclosed is a lower frame structure of a vehicle body, comprising a pair of front longitudinal girders (1), front bottom plate longitudinal girders (2), front longitudinal girder rear parts (3) and doorsill connecting plates (5); the front longitudinal girder rear parts are connected between the front longitudinal girders and the front bottom plate longitudinal girders; each doorsill connecting plate is connected with the lateral side of each front longitudinal girder rear part; a transverse girder (6) is connected between the two front longitudinal girder rear parts; the lower frame structure is characterized in that a reinforced plate (4) is connected between each front longitudinal girder rear part and the doorsill connecting plate connected with each other. The lower frame structure of the vehicle body has the advantages that the structure is reasonable and reliable; when the lower frame structure is applied with right side collision, the energy absorbing area of the front longitudinal girder is ensured to have sufficient deformation, so as to absorb the energy generated by the front collision to the maximal extent and reduce the deformation of the driving cab, the deceleration of the driver and the injury degree of the drivers.
Description
Technical field
The utility model relates to a kind of lower frame structure of auto body.
Background technology
Along with developing rapidly of auto-industry and science and technology, the hommization of automobile is required also to come more to carry high, particularly the protection to driver and crew more and more comes into one's own.At present, the theory of the vehicle structure design-calculated safety performance of generally acknowledging is: during collision case, protect the personal safety of driver and crew in the car to greatest extent, and guarantee effective living space of the interior driver and crew of car before automobile takes place.Therefore, require the vehicle structure design that good front deck collision energy-absorbing effect will be arranged, promptly will reduce the distortion of operator's compartment in the collision process as far as possible.Through retrieval; the Chinese patent communique discloses some vehicle body structures; these structures have certain effect aspect driver and crew's protection; but; still fail to solve very ideally front deck collision energy-absorbing effect; its subject matter is; existing body bottom section framed structure generally all adopts metal plate punching spare to be welded; for example; existing a kind of body bottom section framed structure includes and respectively is a pair of front side member, noseplate longeron, front side member rear portion and threshold connecting panel, and the front side member rear portion is connected in front side member and noseplate longeron.A pair of front side member rear portion all is " Z " font in the said structure, and in the collision process, this " Z " font structural region is very easy to take place defeated and dispersed before generation, thereby causes the gross distortion of operator's compartment, threatens driver and crew's living space; And, because structure defeated and dispersed herein, cause front rail structure energy-absorbing zone fully not absorb before the energy that produced of collision, thereby cause driver and crew in collision process, to be subjected to huge bump.
The utility model content
The purpose of this utility model is exactly to be very easy to take place defeated and dispersed problem in order to solve front side member rear portion " Z " font structural region, and specific aim provides a kind of auto body lower frame structure, when this structure meets accident collision at automobile, can disperse impact force by actv., and impact force is conducted to automobile frame.
For achieving the above object, the utility model adopts following scheme: the lower frame structure of auto body, include and be a pair of front side member, noseplate longeron, front side member rear portion and threshold connecting panel, the front side member rear portion is connected between front side member and the noseplate longeron, each threshold connecting panel is connected with the outside at a front side member rear portion respectively, between two front side member rear portions, be connected with crossbeam, between each front side member rear portion that links to each other and threshold connecting panel, be connected with a brace panel.
Advantage of the present utility model is: by connect a brace panel between each front side member rear portion that links to each other and threshold connecting panel, when head-on crash takes place, can support the impulsive force that is produced by brace panel to operator's compartment, dispersion passes the impact force of underframe longitudinal member forward from front side member, and will impact the energy that is produced and pass through threshold connecting panel conduction body shell, make front side member energy-absorbing zone that fully distortion take place, thereby the energy that collision is produced before absorbing to greatest extent, reduce the distortion of operator's compartment and reduce driver and crew's deceleration/decel with actv., reduce injury values driver and crew.The utility model is rational in infrastructure, reliable, and compared with prior art, safety improves greatly.
Description of drawings
Fig. 1 is the birds-eye view of the utility model embodiment;
Fig. 2 is the block diagram of the utility model embodiment.
The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2:
The lower frame structure of existing auto body, include the front side member rear portion 3 and the threshold connecting panel 5 of a pair of front side member 1, noseplate longeron 2, Z font, front side member rear portion 3 is connected between front side member 1 and the noseplate longeron 2, be connected with crossbeam 6 between two front side member rear portions 3, each threshold connecting panel 5 is connected with the outside at a front side member rear portion 3 respectively.When the said frame structure is subjected to head-on crash at front side member 1, the front side member rear portion 3 of Z font is very easy to take place defeated and dispersed, because structure is defeated and dispersed herein, the energy that collision is produced before causing front rail structure energy-absorbing zone fully not absorb, thus cause driver and crew in collision process, to be subjected to huge bump.
The lower frame structure of the auto body that the utility model provides, on the basis of the lower frame structure of above-mentioned existing auto body, between each front side member rear portion 3 that links to each other and threshold connecting panel 5, be connected with a brace panel 4, the framed structure of brace panel 4 for being bent into by sheet material.By the mode of welding, the bottom of brace panel 4 is connected with the upper end at front side member rear portion 3, and the front end of brace panel 4 and rear end are connected with the front end of crossbeam 6 and threshold connecting panel 5 respectively.In addition, the appearance profile of brace panel 4 is similar to triangle, and the profile that interconnects the position between brace panel 4 and front side member rear portion 3, crossbeam 6 and the threshold connecting panel 5 coincide each other.
When framed structure shown in Figure 2 is subjected to head-on crash at front side member 1, shown in arrow among the figure, can support the impulsive force that is produced by brace panel 4 to operator's compartment, can a part of impact force be passed to threshold connecting panel 5 by brace panel 4 again, dispersion passes the impact force of underframe longitudinal member 2 forward from front side member 1, and the energy that impact is produced is given body shell by 5 conduction of threshold connecting panel, thereby guarantee that fully distortion takes place in front side member 1 energy-absorbing zone, the energy that collision is produced before absorbing to greatest extent, reduce the distortion of operator's compartment and reduce driver and crew's deceleration/decel with actv., reduce injury values driver and crew.
