Abstract
The utility model relates to a forebay plate structure belongs to car component assembly's technical field. Forebay plate structure, including left front floor, well path connection board and right front floor, well path connection board has a section structure that is " nearly " font, and the left side of the section structure of " nearly " font and the section structure of " nearly " font that the right side has an inversion respectively, the welding of left front floor is in the structural formation section of section of " nearly " font of left inversion is tetragonal roof beam I, the welding of right front floor is in the structural formation section of section of " nearly " font of the inversion on right side is tetragonal roof beam II. The utility model discloses a forebay plate structure adopts thick part at the regional well path connection board of the big well passageway of atress, and well passageway reinforcing plate through special structure forebay plate -type one -tenth roof beam structure structure about with has not only reduced the automobile body cost, has disperseed the impact load in addition, has improved collision factor of safety.
Description
Technical field
The utility model relates to the technical field of auto parts assembling, and more particularly, the utility model relates to one and hardens frontlyStructure.
Background technology
As shown in Figure 1, in present structure, front floor 1 is an integrated homogeneous stamping parts. For whole front groundPlate, stressed size is inconsistent. Stressed larger in middle passage area, in order to ensure occupant's safety, need to beMiddle passage area increases reinforcement, and this can cause tare heavier. Single longitudinal beam structure in bottom, floor, in the time of collision,As shown by the arrows in Figure 1, collision energy is from left longeron 2 and right vertical beam 4 front ends longeron 2 and right vertical beam 4 rear ends and left-hand door leftSill beam 3 and right sill strip 5 transmit. The transmission of power is more concentrated, easily causes longeron stressed larger, affects collision safety.
Utility model content
In order to solve the above-mentioned technical problem existing in prior art, the purpose of this utility model is to provide a kind of front floor panel structure.
Floor panel structure before a kind of, is characterized in that: comprise left front floor, middle passage connecting plate and right front floor, described middle passageConnecting plate has the section structure that is " several " font, and the left side of the section structure of described " several " font and right side tool respectivelyThere is the section structure of inverted " several " font; Described left front floor and right front floor are planar structure, and described left frontFloor is welded on by two welding edges and on the section structure of inverted " several " font in described left side, forms section and be tetragonalBeam I, described right front floor be welded on by two welding edges on the section structure of inverted " several " font on described right side, form disconnectedFace is tetragonal beam II.
Wherein, the thickness of described middle passage connecting plate is greater than described left front floor and right front floor.
Wherein, the size of the section structure of described " several " font is greater than the section structure of described inverted " several " font.
Compared with prior art, front floor panel structure described in the utility model has following beneficial effect:
Front floor panel structure of the present utility model, adopts thicker part at the middle passage connecting plate of stressed large middle passage area, logicalThe front floor of middle passage stiffener and left and right of crossing special tectonic forms beam frame structure, has not only reduced vehicle body cost, and has disperseedImpact load, has improved collision safety coefficient.
Brief description of the drawings
Fig. 1 is the structural representation of front floor panel structure of the prior art.
Fig. 2 is the front floor panel structure cross sectional representation of embodiment 1.
Fig. 3 is the structural representation of the front floor panel structure of embodiment 1.
Fig. 4 is the assembly structure schematic diagram of the front floor panel structure of embodiment 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Embodiment 1
As Figure 2-3, front floor of the prior art part is split into three parts by the front floor panel structure described in the present embodiment,Be divided into left front floor 6, middle passage connecting plate 7, and right front floor 8. In stressed larger part, passage connecting plate 7 adoptsThe high-strength steel sheet that thick material is thick, adopts on the left front floor 6 of stressed less part and right front floor 8 ordinary steel that thin material is thickPlate. So just can reduce the stiffener of middle passage area. Left front floor and right front floor adopt planar configuration. Middle passage connectsPlate is by continuous bending, forms large several glyph construction and two little reverse several glyph construction of one, large " several "Glyph construction is in order to dodge blast pipe and power transmission shaft, and the front floor in lower end and left and right of two little " several " glyph construction respectively formsArticle two, welding edge, middle like this passage connecting plate and front floor, left and right have formed a tetragonal beam I and beam II by spot welding. AsShown in Fig. 4, longeron transmits backward in the time being subject to the impact force in front, one-sided by transfer beam 9,10 to longeron 2 rear ends, doorSill beam 3, tri-direction transmission of beam I that middle passage connecting plate and front floor form, can disperse load, improve crashworthiness.Transfer beam 9,10 front ends and longeron 2 weld, and rear end recedes respectively and sill strip 3 and middle passage connecting plate and left front floorThe beam I welding forming, is conducive to the transmission of load, improves the transmission effect of load, improves crashworthiness.
The front floor panel structure of the present embodiment, the impact force that front is subject in the time that vehicle is collided is transmitted to three directions, makes load energyAccess dispersion, improve crashworthiness, better protect occupant safety. This structure is the stressed larger region of plate previouslyPart in passage to increase material thick, the reinforcement of passage in can reducing, has alleviated the weight of vehicle body, has reduced vehicle body cost.The structure of the present embodiment has two row's solder joints on one-sided and front floor, left and right, and between two row's solder joints, has down the roof beam structure knot of " several " fontStructure, this structure can improve the sealing of welding region, can improve the resistance to corrosion of vehicle body, reduces body noise, andAnd can improve the antifatigue damage capability of their welding regions, improve vehicle body durability. The punching press difficulty on the front floor of the present embodimentDegree region is middle channel position, this region far from border more close to, can reduce the punching press difficulty of these parts, can make their useMaterial make DC01 into from DC04, can reduce material cost, thereby reduce vehicle body cost, in follow-up expansion vehicle,As can use to greatest extent existing part when narrowing or broadening floor. The structure of the present embodiment goes for all sedan-chairsThe vehicle such as car, SUV.
For the ordinary skill in the art, being to be understood that can be departing from the utility model scope of disclosure,Can adopt to be equal to and replace or equivalent transformation form enforcement above-described embodiment. Protection domain of the present utility model is not limited to concrete realityExecute the specific embodiment of mode part, as long as no the embodiment that departs from utility model essence, be all interpreted as having dropped on this realityWithin protection domain with novel requirement.
