Abstract
The utility model belongs to the automobile technical field, and particularly relates to a floor girder reinforced structure with high strength. The floor girder reinforced structure comprises a floor girder. A reinforced plate is arranged at the bending position of the floor girder, the reinforced plate is fixed with the floor girder, the reinforced plate is arched, and the arching direction of the arched reinforced plate is opposite to the arching direction of the floor girder. The floor girder reinforced structure has the advantages that due to the fact that the arching direction of the arched reinforced plate is opposite to the arching direction of the floor girder, the floor girder can bear much impact force; the reinforced plate and the floor girder are connected with each other through flanging to form a sealed stable cavity in a closed mode, and therefore deformation of the bending position of the floor girder can be effectively suppressed when collision occurs; the reinforced plate is located in the cavity of the floor girder, therefore, the size of the floor girder is small, and too much installation space is not occupied.
Description
Technical field
The utility model belongs to automobile technical field, especially relates to the higher longitudinal floor beam of a kind of intensity and strengthens structure.
Background technology
Longitudinal floor beam is as the main reinforcement of crew module on vehicle heading, and it keeps firm indeformable can occupant's living space not being damaged that powerful guarantee is provided when vehicle generation head-on crash.But longitudinal floor beam is as the framing member that directly is connected with front side member; when collision takes place; born the most of impact force that passes over from forward engine room; because of its its specific structure shape; usually can deform at the bending part that stress amplitude ratio is concentrated; move behind the coaming plate before causing, destroyed occupant's living space, passenger's safety is caused adverse effect.
Thereby needs are strengthened the structural strength of automotive floor panel longeron, traditional reinforcement mode is the brace panel of fitting along the longeron profile in the longitudinal floor beam indoor design, as notification number be: the reinforcement structure of a kind of automobile longitudinal girder that the Chinese utility model of CN201882151U provides, belong to automobile technical field, the reinforcement structure of this automobile longitudinal girder, comprise the longeron inner panel that is connected on the longeron outside plate, be provided with the bar shaped brace panel in the cavity of longeron inner panel, the both sides of brace panel upwards bend and are connected mutually with the longeron inner panel.Traditional add the thickness that strong method is equivalent to has increased original design, thereby increased the resistance to bending in cross section, but the reinforcement volume that increases newly is big, weight is big, and it is many to increase cost, is unfavorable for the body lightening design.
The utility model content
The utility model mainly is to use that the existing weight of traditional reinforcement is big, volume big, be unfavorable for the problem of body lightening design at existing longitudinal floor beam, provides a kind of a kind of longitudinal floor beam in light weight, that volume is little, solid and reliable to strengthen structure.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of longitudinal floor beam is strengthened structure, comprise longitudinal floor beam, the bending part of described longitudinal floor beam is provided with brace panel, brace panel and longitudinal floor beam are fixed, brace panel is arch, and the direction that arches upward of arch brace panel is opposite with the direction that arches upward of longitudinal floor beam.The direction that arches upward of arch brace panel is opposite with the direction that arches upward of longitudinal floor beam, and from the mechanics angle, when automobile bumped, longitudinal floor beam can bear more impacts, has improved vehicle safety performance.
As preferably, described brace panel comprises a straight section and two bending sections, and two bending sections are connected to the straight section two ends, and the angular range of bending section and straight section is 120 °～150 °.Straight section is used for the carrying impact, and two bending sections are connected the straight section two ends in opened condition, and from the mechanics angle, the bending section structure of open mode can be born bigger impact, and then further improves the structural strength of longitudinal floor beam.
As preferably, be connected with first flange on the described bending section, first flange and longitudinal floor beam welding are fixing.Flange place and longitudinal floor beam fully weld, and make the brace panel of arch and longitudinal floor beam form the firm cavity of sealing, have further increased the structural strength of longitudinal floor beam.
As preferably, the side of described straight section along on be connected with second flange, second flange and longitudinal floor beam welding are fixing.Second flange has further increased the structural strength of longitudinal floor beam.
As preferably, described brace panel is arranged in the die cavity of longitudinal floor beam, and brace panel is located in the die cavity of longitudinal floor beam, makes that this longitudinal floor beam volume is little, does not take too much installing space.
Therefore, the beneficial effects of the utility model are: 1, the direction that arches upward of arch brace panel is opposite with the direction that arches upward of longitudinal floor beam, and longitudinal floor beam can bear more impacts; 2, brace panel interconnects the firm cavity that is closed into a sealing by flange and longitudinal floor beam, can effectively suppress to collide the distortion of longitudinal floor beam band bending position when taking place; 3, brace panel is arranged in the die cavity of longitudinal floor beam, makes that this longitudinal floor beam volume is little, does not take too much installing space.

Accompanying drawing 1 is a kind of perspective view of the present utility model;
Accompanying drawing 2 is front elevations of the present utility model;
Accompanying drawing 3 is a kind of structural representations of brace panel in the utility model.
Shown in the figure: 1-longitudinal floor beam, 2-brace panel, 3-straight section, 4-bending section, 5-first flange, 6-second flange.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As Figure of description 1, shown in 2, a kind of longitudinal floor beam is strengthened structure, comprise longitudinal floor beam 1 and arch brace panel 2, shown in Figure of description 3, brace panel 2 comprises a straight section 3 and two bending sections 4, two bending sections 4 are connected to straight section 3 two ends in opened condition, bending section 4 is 145 ° with the angle of straight section 3, the angle of two bending sections 4 is the obtuse angle, the side of straight section 3 along on be connected with second flange 6, second flange 6 is upwards holded up and is fixing with longitudinal floor beam 1 welding, arch brace panel 2 assumes diamond in shape with longitudinal floor beam 1 integral body and docks, and the direction that arches upward of arch brace panel 2 is opposite with the direction that arches upward of longitudinal floor beam 1, and brace panel 2 is arranged in the die cavity of longitudinal floor beam 1, it is fixing with longitudinal floor beam 1 welding to be connected with first flange, 5, the first flange 5 on the bending section 4.
A kind of longitudinal floor beam that the utility model provides is strengthened structure, be installed in band bending position in the longitudinal floor beam die cavity, global shape is arch band flanging structure, interconnect the firm cavity that is closed into a sealing with longitudinal floor beam, can effectively suppress to collide the distortion of longitudinal floor beam band bending position when taking place, thereby guarantee occupant's living space stability, the shape that should strengthen structure in addition also can be the arch configuration of rounding off, and other are constant.
This brace panel structure has that volume is little, and quality is little, and cost is low, make and welding process simple, advantages such as easy realization, and provide good realization approach to the light-weight design of vehicle body.
