Description
Technical field
This utility model relates to a kind of anti-collision rod assembly, especially a kind of high-tension anti-collision rod assembly.
Background technology
At present, in today of high speed development, automobile becomes the requisite walking-replacing tool of people.Along with automobile in daily life universal, the safety problem of automobile is the most increasingly paid close attention to by consumer.And the full performance of automobile is not only embodied in air bag, ABS etc. and configures above, it is also embodied in the structure of vehicle body.Anti-collision rod assembly is as automobile safety components, it is the Focusing on components of Automobile Design, its design process should ensure security performance, meet vehicle modeling requirement again and take into account the light-weighted requirement of product, also to meet the construction cycle short, the requirement of low cost of manufacture simultaneously.
Anti-collision rod assembly structure many employings crash bar of automobile adds the mode of collision energy absorbing box at present, and collision energy absorbing box is symmetrical, although well but manufacturability is poor for this box-shaped design energy-absorbing effect.Opening a grade dimension precision requirement height between energy-absorption box upper plate and energy-absorption box lower plate, therefore Sheet Metal Forming Technology requires relatively high, and the mode of protection weldering can only be used when with Crashworthy plate 4 spelling to be connected, and welding usability is poor.This kind of design is for being that installed surface is relatively large to the requirement of crashproof installing plate installed surface simultaneously, is unfavorable for light-weight design.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of simple in construction, the high-tension anti-collision rod assembly that anti-collision energy absorption is effective.
This utility model solves its technical problem and be the technical scheme is that a kind of high-tension anti-collision rod assembly, including the first bearing, the second bearing and be across the crash bar between the first bearing and the second bearing, also include three abutments, described crash bar includes two mounting planes that position is relative, and crash bar is positioned between two mounting planes, two mounting planes are respectively outer mounting plane and interior mounting plane, wherein the first bearing and the second bearing are fixed at interior mounting plane, and three abutments is fixed at outer mounting plane；Described three abutments is positioned at the middle position of crash bar；Described crash bar is arcuate structure, and the centering angle of this crash bar is 120 ° ~ 175 °, and the arc core of crash bar is towards direction, interior mounting plane place.
The beneficial effects of the utility model are: crash bar is installed at car door, and outer mounting plane is that interior mounting plane is towards the surface in car on crash bar towards the surface outside car on crash bar.First bearing and the second bearing are positioned at the two ends of crash bar and fix with mounting plane, and three abutments is positioned at the central authorities of crash bar and fixes with outer mounting plane, thus from crash bar both sides, crash bar is fixed, and from two corresponding flats, crash bar is stretched, improve the stability that crash bar is fixing.It addition, crash bar is arcuate structure, arc core is towards interior mounting plane, namely protrusion is towards outer mounting plane, when there is impact, impulsive force exerts a force towards interior mounting plane direction from outer mounting plane, therefore this arcuate structure can function well as buffer compression effect, improve the buffering effect of crash bar.
First bearing is slab construction, and the first bearing is provided with some installing holes arranged along the first bearing edge；Second bearing is slab construction, and the second bearing is provided with some installing holes arranged along the second bearing edge.The bearing of slab construction can more firm and stably be fixed with car door, especially ensures the situation that crash bar will not depart from car door when by impacting, improves stability in the large.
Wherein, the cross sectional shape of crash bar is circular, can preferably play collision prevention function, even and if send bending, circular configuration is also not easy the injury unnecessary to occupant.
Three abutments is U-shape structure, and described crash bar is fixed on the opening part of three abutments, thus improves three abutments and the stability of crash bar installation, it is to avoid get loose between the two.
Further preferably, the centering angle of crash bar is 165 °.

Fig. 2 is the top view of Fig. 1.
Fig. 3 is the sectional view of this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As shown in Figure 1, 2, 3, the present embodiment includes first bearing the 11, second bearing 12 and is across the crash bar 2 between the first bearing 11 and the second bearing 12.It is also equipped with three abutments 13 at the middle part of crash bar 2, crash bar 2 includes two mounting planes that position is relative, and crash bar 2 is positioned between two mounting planes, two mounting planes are respectively outer mounting plane 21 and interior mounting plane 22, wherein the first bearing 11 and the second bearing 12 are fixed at interior mounting plane 22, three abutments 13 is fixed at outer mounting plane 21, and three abutments 13 is positioned at the middle position of crash bar 2.Crash bar 2 is arcuate structure, and the centering angle of this crash bar 2 is 165 °, and the arc core of crash bar 2 is arranged towards direction, interior mounting plane 22 place.
First bearing 11 is slab construction, and the first bearing 11 is provided with some installing holes arranged along the first bearing 11 edge；Second bearing 12 is slab construction, and the second bearing 12 is provided with some installing holes arranged along the second bearing 12 edge.The bearing of slab construction can more firm and stably be fixed with car door, especially ensures the situation that crash bar will not depart from car door when by impacting, improves stability in the large.Wherein, the cross sectional shape of crash bar 2 is circular.Three abutments 13 is U-shape structure, and crash bar 2 is fixed on the opening part of three abutments 13, thus improves three abutments 13 and the stability of crash bar 2 installation, it is to avoid get loose between the two.
In this utility model, crash bar 2 is installed at car door, and outer mounting plane 21 is that interior mounting plane 22 is towards the surface in car on crash bar 2 towards the surface outside car on crash bar 2.First bearing 11 and the second bearing 12 are positioned at the two ends of crash bar 2 and fix with mounting plane 22, and three abutments 13 is positioned at the central authorities of crash bar 2 and outer mounting plane 21 is fixed, thus from crash bar 2 both sides, crash bar 2 is fixed, and from two corresponding flats, crash bar 2 is stretched, improve the fixing stability of crash bar 2.Additionally, crash bar 2 is arcuate structure, arc core is towards interior mounting plane 22, namely protrusion is towards outer mounting plane 21, when there is impact, impulsive force exerts a force towards interior mounting plane 22 direction from outer mounting plane, therefore this arcuate structure can function well as buffer compression effect, improves the buffering effect of crash bar 2.
