Description
Technical field
The utility model belongs to automotive body structure technical field, and in particular under a kind of floor for improving side impact performance
Beam structure.
Background technology
In recent years, with universal and driver's quantity the surge of private car, traffic accident also becomes more next
It is more.Therefore, the awareness of safety of people is further waken up, the table when buying vehicle for product when happening suddenly emergency
Now more pay close attention to.So how to improve the collision performance of vehicle, vehicle is allow preferably to protect the person of driver and passenger
Safety is always the direction that all big enterprises make great efforts.
Existing floor Lower Crossbeam Structure needs for technique, needs to open multiple gap on it, affects its intensity, drops
Low side impact performance.In addition, existing structure needs to separately design different specific aims for the requirement for meeting welding or being spirally connected
Structure, cause inconvenience.
Invention content
The purpose of this utility model is：A kind of floor Lower Crossbeam Structure for improving side impact performance is provided, it is existing to solve
The problems in technology.
The utility model is achieved by the following technical solution：A kind of floor bottom end rail knot for improving side impact performance
Structure, including the floor bottom end rail main body that section is " several " font, the top of main body is high for both sides, and intermediate low spill is included in
First plane of body top both sides, in the intermediate incline of two planes of the second plane and connection at middle part；In the second plane
Mounting hole is equipped with, fixed seat is equipped on intermediate incline；It is additionally provided with the reinforcing rib of Y types, the reinforcement on the first plane
Muscle lower end is extended to above the fixed seat of intermediate incline；Strengthen in the side of the floor bottom end rail main body of " several " font equipped with side
Muscle is equipped with flange at both ends and bottom end, and technique gap is equipped in the intersection of flange.
Further：The side reinforcing rib penetrates through entire crossbeam.
Further：The side reinforcing rib is the U-shaped kept flat, is turned back before welding surface.
The beneficial effects of the utility model are：The main body of the utility model structure does not have technique gap, so rigidity is high, strong
It spends, advantageously reduces the injury caused by collision；This structure does not influence number of welds and position, does not influence processing technology,
Influence to processing and manufacturing is small；This structure versatility is high, is applicable to different vehicles；This structure strong applicability, is spirally connected, welding
This structure can be used.
Description of the drawings
Fig. 1 is the utility model structure of the main view；
Fig. 2 is the utility model part-structure schematic diagram；
Fig. 3 is the bottom view of Fig. 2；
Fig. 4 is the utility model structural section schematic diagram；
Fig. 5 is the structure diagram of one embodiment；
Fig. 6 is the structure diagram of another embodiment.
Number explanation in figure：1 it is floor bottom end rail main body, 2 be the first plane, 3 be the second plane, 4 is intermediate incline, 5
It is fixed seat for mounting hole, 6,7 be reinforcing rib, 8 be side reinforcing rib, 9 be flange, 10 is technique gap.
Specific embodiment
It is as shown in figures 1 to 6 a kind of floor Lower Crossbeam Structure for improving side impact performance of the utility model structure, including cutting
Face is the floor bottom end rail main body 1 of " several " font, and the top of main body is high for both sides, and intermediate low spill is included in body top
First plane 2 of both sides, in the intermediate incline 4 of two planes of the second plane 3 and connection at middle part；It is set in the second plane
There is mounting hole 5, fixed seat 6 is equipped on intermediate incline；It is additionally provided with the reinforcing rib 7 of Y types, the reinforcing rib on the first plane
Lower end is extended to above the fixed seat of intermediate incline；Side reinforcing rib is equipped in the side of the floor bottom end rail main body of " several " font
8, flange 9 is equipped at both ends and bottom end, technique gap 10 is equipped in the intersection of flange.
Preferably：The side reinforcing rib penetrates through entire crossbeam.
Preferably：Side reinforcing rib be the U-shaped structure kept flat, turn back before welding surface is extended to.
The utility model structure reduces technique gap, and formed and sealed with parts such as B columns, roof bows by face of more retrofiting
Closed loop improves collision performance, reduces the intrusion volume of B columns.The part mainly with longeron and middle channel bottom end rail or threshold into
Row overlap joint, so basic structure is " several " font, as shown in Figure 4.
Punching press demand is met by the form of mouth open and clear on flange, as shown in Fig. 2, ensureing the complete of part main body
Property rather than excision entire three face junction, improve part entirety rigidity.In the position overlapped with longeron, do one and pass through
The reinforcing rib of chamfering position, shape need to meet welding space, as shown in figure 3, being in Y-direction stress, increase stress in this way
Section improves rigidity, power is allowed preferably to hand on, reduces the damage risk of bending part.
Reinforcing rib is done at face 1 shown in Fig. 4 and face 2, increases Y-direction rigidity, according to screw connection manner, then as shown in Figure 5
Reinforcing rib penetrates through entire crossbeam, and according to welding manner, then reinforcing rib as shown in Figure 6 stops and turned back at welding surface.
The main body of the utility model structure does not have technique gap, so rigidity is high, intensity is good, advantageously reduces collision and is made
Into injury；This structure does not influence number of welds and position, does not influence processing technology, and the influence to processing and manufacturing is small；This knot
Structure versatility is high, is applicable to different vehicles；This structure strong applicability, is spirally connected, this structure can be used in welding.
