Description
Technical field
The utility model relates to automobile technical field, in particular to a kind of threshold internal support.
Background technique
With the development of society, people increasingly pay attention to the safety problem of automobile, it is desirable that it can bear stringent central collision, side
It touches, the safety of driver and occupant is made to be guaranteed.In new car crash tests NCAP(New Car Assessment
Program) in evaluation, crew module's rigidity and occupant injury have direct relationship, and crew module's rigidity is big, and cabin deforms in an impact
Small, the living space of occupant is just guaranteed, and the injury of occupant will reduce accordingly.
Vehicle doorsill girder is most important power transmitting and energy absorbing component in automobile collision procedure, when side collision occurs for vehicle,
It can absorb substantial portion of energy when collision, and the quality and deformation velocity of deformation all have weight to vehicle and occupant safety
The meaning wanted.When body construction designs, general main thought is to improve the structural strength of sill strip and seat beam, such as increases knot
Structure thickness, the bigger material of use intensity, this design method be easy to cause design cost increasing, technique to be difficult to carry out.In addition,
, seat beam small for threshold terrain clearance is arranged in this kind of car body below floor, and sill strip is to multiplying during side collision
Member's space inner bending causes collision intrusion volume larger.In this case the simple intensity effect for increasing threshold or crossbeam is not
Good, to reducing, occupant injury effect is unobvious.It, can be in threshold interior design branch in order to improve Structural Crashworthiness when automobile side crash
Member structure, the fine or not Cheng Du of structural strength have become the increasing problem of automobile door sill design aspect attention rate.
Utility model content
The purpose of this utility model is just to provide a kind of threshold internal support, has good rigidity, can rise to threshold
To preferable booster action.
The purpose of this utility model is achieved in that a kind of threshold internal support, including left plate, right side plate and company
Fishplate bar, left plate and right side plate setting are in " several " font in connecting plate two sides, and left plate and right side plate are equipped with outside flange knot
Structure；It further include support plate, support plate is connected with left plate, right side plate and connecting plate constitutes box body structure.
In the present invention, " several " font supporting element includes left plate, right side plate and connecting plate；Left plate and right side plate
It is arranged in connecting plate two sides, can be integral piece and be also possible to weld together；Support plate and " several " font supporting element weld
Or be integrally formed and constitute box body structure, there is good rigidity, preferable booster action can be played to threshold.
When in use, box body structure is arranged in threshold, and left plate and right side plate are perpendicular to sill strip, the support plate on top
It is also perpendicularly to sill strip, whole and sill strip welds together.Left plate and right side plate are equipped with outside turnup structure, further
Whole rigidity is improved, entire box body structure plays preferable booster action to threshold during side impact.
By adopting the above-described technical solution, the utility model has the advantage that it not only designs lightweight, processing
Simply, stock utilization is improved, also there is good rigidity, preferable booster action can be played to threshold.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples:
As shown in Figures 1 to 4, a kind of threshold internal support, including left plate 1, right side plate 2 and connecting plate 3, left plate
1 and the setting of right side plate 2 in 3 two sides of connecting plate be in " several " font, left plate 1 and right side plate 2 are equipped with outside turnup structure 4；Also
Including support plate 5, support plate 5 is connected with left plate 1, right side plate 2 and connecting plate 3 constitutes box body structure.
In the present invention, " several " font supporting element includes left plate 1, right side plate 2 and connecting plate 3；Left plate 1 and the right side
Side plate 2 is arranged in 3 two sides of connecting plate, can be integral piece and is also possible to weld together；Support plate 5 and " several " font support
Part welding is integrally formed composition box body structure, has good rigidity, can play preferable booster action to threshold 8.
When in use, box body structure is arranged in threshold 8, and left plate 1 and right side plate 2 are perpendicular to sill strip, the branch on top
Fagging 5 is also perpendicularly to sill strip, and whole and sill strip welds together.Left plate 1 and right side plate 2 are equipped with outside turnup structure
4, whole rigidity is further increased, entire box body structure plays preferable booster action to threshold 8 during side impact.According to
It needs that 1 or more than one box body structure can be used in threshold 8
Further, as shown in Figures 1 to 4, left plate 1 and right side plate 2 are equipped with aperture.The setting of aperture can optimize
Material distribution, reduces the material to rigidity of structure contribution amount compared with lower part, improves stock utilization, realizes lightweight.
Further, as shown in Figures 1 to 4, aperture is square opening 11.It is light-weighted simultaneously in realization, it is more attractive
The use of less material.
Further, 4 quantity of turnup structure on left plate 1 and right side plate 2 is one or more.As shown in Figure 1 to Figure 4
