The vehicle body front floor reinforcing structure is a structure light in weight, low in cost and capable of meeting vehicle body strength, and the structure may solve the problem of the prior art that the addition of the quantity or thickness of reinforcing plates causes vehicle weight increase and has high practical value.
Description
Technical field
The present invention relates to automobile manufacturing field, be specifically related to a kind of automobile front floor reinforced structure.
Background technology
The collision safety performance of automobile is problem particularly critical in the many key performances of automobile, has obtained the extensive attention of countries in the world main engine plants and ordinary consumer.In front floor of automobile body, reinforcing plate is the collision safety structural member that vehicle body leading portion is crucial.In the front floor of the most a lot of vehicles, reinforcing plate is all that simple punching press section structure is welded on below front floor, and its cross sectional shape is relatively simple, and expects thickness or increase reinforcing plate quantity to improve integrally-built security performance often by increasing.But, thick or reinforcing plate quantity the increase of material will certainly increase complete vehicle weight, thus constrains again car load power economy and other other performances directly related with weight.
Summary of the invention
The technical problem to be solved is to provide a kind of torsional rigidity that both can promote vehicle body and complete automobile collision security performance, and new structure can be by cancelling section structural to alleviate the automobile front floor reinforced structure of tare simultaneously.
For solving above-mentioned technical problem, the present invention provides techniques below scheme:
A kind of vehicle body front floor board reinforcement structure, including front floor, front longitudinal floor beam, reinforcing plate, described front floor is affixed in joint place with front longitudinal floor beam, described reinforcing plate is located in the box-like closed area that front floor is enclosed mutually with front longitudinal floor beam, described reinforcing plate is made up of an integral plate, including a gripper shoe and
Having the upper overturning of vertical bending and lower flange on the both sides that gripper shoe is longitudinal, described upper overturning is parallel reversely with lower flange, and reinforcing plate cross section is Z-shaped, and described upper overturning is fixedly linked with the laminating of front floor, and described lower flange is fixedly linked with the laminating of front longitudinal floor beam.
Further, described on front floor, front longitudinal floor beam joint place welding be allowed to connected.The mode using welding is connected fixing to front floor and front longitudinal floor beam.
Further, described gripper shoe is provided with a plurality of reinforcement along gripper shoe genesis analysis.The rigidity of whole reinforcement structure is added by setting up reinforcement.
Further, described on front floor perforate be connected with upper overturning plug welding, on front longitudinal floor beam, perforate is connected with lower flange plug welding, and described putting at front floor top plug welding position is intersected with the plug welding location dislocation on corresponding front longitudinal floor beam.Reinforcing plate is fixed on front floor and front longitudinal floor beam by the mode using plug welding, uses the position welding of staggered cross can effectively reduce welding residual stress.
The present invention compared with prior art has the beneficial effect that the present invention is that front floor, reinforcing plate and one inside of front floor reinforcement welding formation have the closed frame structure enough supported, front floor can provide by this reinforcement structure that one is the most lightweight, low cost, can meet again bus body strength, solving increases reinforcing plate quantity present in prior art or material is thick and problem that bring car weight increases.

Detailed description of the invention
In order to the purpose invented, technical scheme and advantage are clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.
See shown in Fig. 1 to Fig. 4, a kind of vehicle body front floor board reinforcement structure, including front floor 2, front longitudinal floor beam 4, reinforcing plate 3, described front floor 2 and front longitudinal floor beam 4 are affixed in joint place, described reinforcing plate 3 is located in the box-like closed area that front floor 2 is enclosed mutually with front longitudinal floor beam 4, described reinforcing plate 3 is made up of an integral plate, the upper overturning 3.1 of vertical bending and lower flange 3.2 is had including a gripper shoe 3.3 with on the both sides that gripper shoe is longitudinal, described upper overturning 3.1 is parallel reversely with lower flange 3.2, reinforcing plate cross section is Z-shaped, described upper overturning 3.1 is fixedly linked with the laminating of front floor 2, described lower flange 3.2 is fixedly linked with the laminating of front longitudinal floor beam 4.
Described on front floor 2, front longitudinal floor beam 4 joint place welding be allowed to connected.Described gripper shoe is provided with a plurality of reinforcement 1 along gripper shoe 3.3 genesis analysis.Described on front floor 2 perforate be connected with upper overturning 3.1 plug welding, on front longitudinal floor beam, perforate is connected with the plug welding of lower flange 3.2, described front floor 2 top plug welding position put 5 with plug welding position 5 staggered cross on corresponding front longitudinal floor beam.
It is an object of the invention to use a kind of torsional rigidity that both can promote vehicle body of new structure and complete automobile collision security performance, new structure can be by cancelling section structural to alleviate tare simultaneously.The present invention increases the reinforcing plate 3 that cross section is Z-shaped in using the box-like closed area enclosed on front floor 2 with front longitudinal floor beam 4 phase, the upper overturning 3.1 of reinforcing plate is connected with front floor 2 plug welding, the lower flange 3.2 of reinforcing plate is connected with the plug welding of front longitudinal floor beam 4, add the rigidity of whole reinforcing plate by setting up reinforcement, forming the inside closed has the car floor reinforcement structure of strong support.The welding position 5 using staggered cross can effectively reduce welding residual stress.By when collision or side collision, the anterior intensity in member cabin and rigidity can be greatly promoted, reduces the deformation on front floor, can effectively protect the safety in member cabin before automobile sends.Simultaneously need not be again in order to improve that integrally-built security performance is logical and to increase material thick or increase reinforcing plate quantity.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
