Abstract
The utility model relates to a beam assembly before preceding floor belongs to the technical field of car structural design and manufacturing. The utility model discloses a beam assembly before preceding floor, tie -beam including the left front floor before, tie -beam before the right front floor is with the preceding floor front beam of fonts nearly cheng, the tie -beam welds before the left end of preceding floor front beam and the left front floor, the tie -beam welds before the right -hand member of preceding floor front beam and the right front floor. Bounding wall and preceding floor connection zone do not have the crossbeam before in prior art, and the volume of retreating of bounding wall is bigger before the upon impact. The utility model discloses a volume of retreating of bounding wall before beam assembly before preceding floor can reduce is favorable to reducing steering column, accelerator pedal, brake pedal, the volume of retreating of parts such as air conditioner, guarantee passenger's safety.
Description
Technical field
The utility model belongs to the technical field of structure design of automobile and manufacture, and in particular, the utility model relates to a kind of front floor front beam assembly.
Background technology
As shown in Figure 1-2, in the prior art, current front coaming plate 1 and front floor 2 are generally direct welding, there is no crossbeam at their join domain. So the front coaming plate between left front girder 3 and front right longitudinal beam 4 and the overlap joint region on front floor are without crossbeam. Cause front coaming plate and front longitudinal can not well power be passed to opposite side one side is stressed when collision, load more concentrated, front coaming plate stressed larger. Make the amount of retreating of front coaming plate larger, have influence on occupant's safety.
Utility model content
In order to solve above-mentioned technical problem of the prior art, the purpose of this utility model is to provide a kind of front floor front beam assembly.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of front floor front beam assembly, is characterized in that: comprise tie-beam before left front floor, tie-beam before right front floor, with the front floor front beam that becomes down several fonts; Tie-beam welding before the left end of described front floor front beam and left front floor, tie-beam welding before the right-hand member of described front floor front beam and right front floor.
Compared with prior art, front floor described in the utility model front beam assembly has following beneficial effect:
Front coaming plate and front floor join domain do not have crossbeam in the prior art, and before when collision, the amount of retreating of coaming plate is larger. The front floor front beam assembly of the utility model design, the load that can disperse front coaming plate and front coaming plate crossbeam, before reducing, coaming plate is stressed, reduce the amount of retreating of front coaming plate, be conducive to reduce steering column, gas pedal, brake pedal, the amount of retreating of the parts such as air-conditioning, guarantee occupant's safety.

Detailed description of the invention
Below with reference to specific embodiment, front floor described in the utility model front beam assembly is further elaborated, with help those skilled in the art to utility model of the present utility model conceive, technical scheme has more complete, accurate and deep understanding.
Embodiment 1
Between front coaming plate and front floor, increase laterally connect fall the front floor of several fonts front beam assembly. As shown in Fig. 3-6, front floor front beam assembly described in the present embodiment, comprise tie-beam 5 before left front floor, tie-beam 7 before right front floor, front floor front beam 6, tie-beam welding before the left end of described front floor front beam and left front floor, tie-beam welding before the right-hand member of described front floor front beam and right front floor. Before left front floor, tie-beam 5 is first welds with left front girder, and before right front floor, tie-beam 7 first welds with right vertical beam. After front floor front beam 6, with left front girder assembly and the anterior roof beam structure assembly of front right longitudinal beam assembly welding formation, make left-right longeron can form syndeton in this region by front floor front beam. Front portion and the front coaming plate 1 of front floor front beam weld, rear portion and front coaming plate 1, and front floor 2 is three layers of welding together. In order to dodge the vehicle chassis component of middle passage bottom, before front floor, the height of connecting cross beam does not need very large, general warranty is in about 20mm, that is to say before front floor that connecting cross beam is at non-welding region and front coaming plate about the minimum range guarantee 20mm in Z-direction. Coaming plate front beam 8 before the central region of front coaming plate has, thus before the crossbeam of front coaming plate joint area left-right longeron has coaming plate front beam and front floor front beam.
The present embodiment by the region of front coaming plate, increases connecting cross beam and front coaming plate front beam before front floor, is connected in the annular that can form together two sealings with left and right front longitudinal of left-right longeron. The front floor front beam increasing, the load that can disperse front coaming plate and front coaming plate crossbeam, before reducing, coaming plate is stressed, has strengthened the connection on front coaming plate and front floor, and the benefit of doing like this has:
1 can transmit by front coaming plate front beam and front floor front beam by the stressed of left-right longeron in the time of collision, disperses load, can reduce the amount of retreating of front coaming plate, ensures occupant's safety.
2 have increased crossbeam between front coaming plate and front floor, are equivalent to strengthen the overlapping region between them, and part strengthens, so can reduce their fatigue rupture, have increased the vehicle body life-span.
3 by connecting cross beam before the front floor increasing, and the load that can make front coaming plate and front coaming plate front beam be subject to has obtained dispersion, so it is thick suitably to reduce the material of front coaming plate and front coaming plate crossbeam, reduces tare and cost.
The crossbeam that 4 bottoms between front coaming plate and front floor increase, can play the protective effect on front coaming plate and front floor, has avoided steam by join domain into the car, has improved the rustless property of vehicle body.
5 by connecting cross beam before the front floor increasing, and makes vehicle body increase the connection of a left and right, so can increase rigidity and the mode of vehicle body, has improved the manipulation stability of vehicle body.
The new model such as car, SUV that front floor front beam assembly described in the present embodiment goes for Future Development uses.
For the ordinary skill in the art; specific embodiment is just exemplarily described the utility model; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
