Abstract
The invention relates to an automobile floor structure, in particular to a floor structure which can be connected with a chassis and transmit force. A beam is added to a floor assembly and meanwhile a mount structure connecting the automobile body and the chassis is arranged on the beam. During the lateral collision of the whole automobile, the structure transmits the lateral collision force from the beam to the chassis so as to make full use of the chassis to bear the lateral collision force, lower the damage to the cab and protect the members.
Description
Technical field
The present invention relates to a kind of automotive floor panel structure, relate to a kind of floor panel structure that can connect to ground and carry out power transmission particularly.
Background technology
Along with the fast development of auto manufacturing technology and the raising of people's living standard, automobile has begun to enter ordinary people's family, becomes the vehicle important in broad masses' daily life.Thereupon, people are harsh more for the requirement of vehicle safety performance.Various safety collision rules are put into effect in succession, side face collision safety performance requriements wherein, because of its in collision process, member's safety has been played and important protective effect, more and more be subjected to people's attention.In the side collision process, important effect has been played on the floor, although in body-chassis frame construction, is mainly born the effect of side collision force by vehicle frame, and the effect on floor is still very important.Because in side collision, the side outside plate elder generation contact impact thing of the body of at first being collided passes to vehicle frame by the floor with side collision force then, bears side collision force by vehicle frame.Can preferably side collision force is passed to vehicle frame, the structure on floor have played crucial effects.Therefore, be necessary further to optimize the structure on floor, so that improve the side impact safety performance of car load, protection member's safety.And in the present vehicle body floor structure, on safety performance, the safety performance when mainly having considered head-on crash.But do not consider the safety performance requirement of floor when side collision, have certain defective.
Summary of the invention
The safety performance problem that exists in the floor panel structure when the present invention is directed to present side collision has proposed an enforceable solution, by improving structure, improves the ability of vehicle opposing side collision, better protection member's safety.
The floor panel structure that the purpose of this invention is to provide a kind of transmission side collision force that can be good is so that improve the anti-side collision ability of car load.
Technical scheme provided by the invention is:
Increase crossbeam in floor assembly, the suspension point structure that will connect vehicle body and vehicle frame simultaneously is placed on the crossbeam.By this structure, when the car load side collision, the impact force of side is passed to vehicle frame by crossbeam, bear side collision force so that make full use of vehicle frame, reduce degree of tortuosity, protection member's safety to operator's compartment.
A kind of car body floor structure, this floor panel structure has floor, floor crossmember and suspension point installing mechanism, floor crossmember is provided with suspension point mechanism, is coupled between this suspension point mechanism and the suspension point installing mechanism, and floor panel structure connects to ground by the suspending mechanism of this coupling.
Wherein, described floor panel structure also has the floor side side bar, and it is connected with floor crossmember, power is passed to floor crossmember in the side when stressed.And it is whole adopting spot-welded between the floor in this floor panel structure, floor crossmember, suspension point installing mechanism and the floor side side bar.
The suspension point mechanism that is arranged on the floor crossmember connects vehicle frame and car load vehicle body.During the vehicle body lateral force, this power at first acts on the body side wall outside plate, and is passed to threshold brace panel and threshold by side-wall outer-plate, is passed to floor and floor crossmember again, and finally the suspending mechanism by coupling is passed to vehicle frame.
A kind of car body floor structure increases crossbeam in floor assembly, and the suspension point mechanism that will connect vehicle body and vehicle frame is arranged on the crossbeam.
Wherein, described floor assembly has floor, floor side side bar, floor crossmember and suspension point installing mechanism, and wherein floor crossmember is provided with the suspension point mechanism that is of coupled connections with the suspension point installing mechanism.The suspension point installing mechanism cooperates with suspension point mechanism vehicle frame is connected with the vehicle body that comprises floor panel structure.The lateral force of car body is passed to floor crossmember by the floor side side bar, and is passed to vehicle frame by the suspending mechanism that is arranged on the coupling on the floor crossmember.
Above-mentioned floor panel structure can be with its stressed vehicle frame that is passed to.
By said structure, when the car load side collision, the impact force of side is passed to vehicle frame by crossbeam, bear side collision force so that make full use of vehicle frame, reduce degree of tortuosity, protection member's safety to operator's compartment.

Description of reference numerals:
The 1-side-wall outer-plate, 2-threshold, 3-floor, 4-suspension point installing mechanism, 5-floor crossmember, 6-vehicle frame, 7-suspending mechanism, 8-threshold brace panel
The specific embodiment
The floor panel structure that is used for self-propelled vehicle comprises the suspension point installing mechanism between floor, floor side side bar, floor crossmember and vehicle body and the vehicle frame, and each part mentioned above becomes an integral body by spot-welded on.The suspension point that connects vehicle body and vehicle frame is arranged on the floor crossmember; when side collision takes place; the collision thing at first clashes into the floor side side bar; and collision energy is passed on the floor crossmember with its weld together; by being arranged on the suspension point mechanism on the floor crossmember, collision energy is passed on the vehicle frame, finally bear the energy that collision produces by vehicle frame; improve the anti-side impact ability of car load, better protection member's safety.
As shown in Figure 1, when side collision took place, the collision thing at first contacted side-wall outer-plate 1, and the energy that collision simultaneously produces is passed to threshold brace panel 8 and threshold 2 via side-wall outer-plate direction in car, and then is passed to coupled floor 3 and floor crossmember 5.Because vehicle frame 6 links to each other with car load by suspending mechanism 7 and suspension point installing mechanism 4, therefore collision energy can be passed to vehicle frame 6 by suspending mechanism 7, bear the side impact energy by vehicle frame, improve the car load safety performance, protection member's safety.
