Description
Technical field
The utility model relates to a kind of automobile safety components, can especially improve the small offset collision stress of vehicle
Energy-absorption box.
Background technique
Front anticollision beam of automobile is located at the front end of vehicle body, by crossbeam, two side connecting plates, two sides energy-absorption box, two sides bottom plate etc.
Four parts composition, front anticollision beam of automobile are connect by bottom plate with stringer.The main function of front anticollision beam of automobile is in low speed collision
Under, by its high-intensitive structure, by the energy transmission of collision to energy-absorption box, the deformation by energy-absorption box absorbs energy, plays one
Fixed buffer function reduces the degree of vehicle body damage to play a protective role to occupant on vehicle, reduces maintenance cost.With
The continuous improvement that people require automotive safety, vehicle crash test are also more and more harsh.U.S. IIHS has been proposed 25%
Small offset collision test request.25% small offset collision is exactly that vehicle only has the area in front 25% and non-deformable rigid walls
Barrier collides, and impact velocity is about 64km/h.The head-on crash of relatively large area, pressure suffered by small offset collision part
Bigger, the probability that occupant is hurt is higher.Its axis of existing energy-absorption box is essentially coincided with stringer, in small offset collision mistake
The registration of Cheng Zhongyu obstacle is low, and when collision is difficult to impact force being effectively passed to stringer, causes vehicle energy-absorbing insufficient, hits
Energy transmission damages occupant to crew module.
Utility model content
The purpose of this utility model is that aiming at the disadvantages of the prior art, providing a kind of small offset collision stress of improvement vehicle
The energy-absorption box of state, the energy-absorption box can be improved the energy-absorbing effect under small offset collision, reach and preferably protect occupant's
Purpose.
Problem described in the utility model is realized with following technical proposals:
A kind of energy-absorption box improving the small offset collision stress of vehicle, including energy-absorbing box body and soldering are in energy-absorption box sheet
The connecting plate and bottom plate of body rear and front end, the energy-absorbing box body are the wedge shape cavity tetrahedral structure being obliquely installed, energy-absorption box
The front end of ontology is to beam-end Directional Extension, the rear end of energy-absorbing box body and stringer pairing.
The energy-absorption box of the above-mentioned small offset collision stress of improvement vehicle, the lateral surface of each energy-absorbing box body are relatively interior
Side gradient angle a is 30 °~60 °.
The energy-absorption box of the above-mentioned small offset collision stress of improvement vehicle, the lateral surface rear of each energy-absorbing box body installs
Two reinforcing ribs are set, each energy-absorbing box body is provided with a circumferential crumple guiding groove close to forward position.
The energy-absorption box of the above-mentioned small offset collision stress of improvement vehicle, energy-absorbing box body by two pieces of stamping parts soldering and
At weld seam is located at the top and the bottom of energy-absorbing box body.
Energy-absorption box described in the utility model has an advantage that energy-absorption box using wedge structure and energy-absorbing compared with prior art
The front end of box is to beam-end Directional Extension.The structure can conduct impact force to stringer when small offset collision occurs for vehicle,
So as to improve the crumple form of stringer, the registration of energy-absorption box and obstacle during small offset collision is improved, improves energy-absorbing effect
Fruit is conducive to improve safeguard protection of the small offset collision in the process to occupant to reduce the deformation of crew module.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the perspective view of energy-absorbing box body.
Fig. 3 is the utility model use state diagram；
The small offset collision schematic diagram of Fig. 4 the utility model；
Fig. 5 is the small offset collision schematic diagram of the prior art.
Each list of reference numerals in figure are as follows: 1, connecting plate, 2, energy-absorbing box main body, 2-1, reinforcing rib, 2-2, crumple guiding groove, 2-3,
Weld seam, 3, bottom plate, 4, crossbeam, 5, obstacle, 6, stringer.
Specific embodiment
Referring to Fig. 1-Fig. 3, the utility model includes the connection of energy-absorbing box body 2 and soldering in energy-absorbing box body rear and front end
Plate 1 and bottom plate 3.Energy-absorbing box body is formed by two pieces of stamping parts soldering, and weld seam 2-3 is located at the top and the bottom of energy-absorbing box body.
Connecting plate matches soldering, bottom plate and 6 soldering of stringer with crossbeam 4.The energy-absorbing box body is the wedge shape cavity four sides being obliquely installed
Body structure, use state shown in Fig. 3, energy-absorption box are located at the both ends of crossbeam 4, and the front end of energy-absorbing box body is to beam-end side
To extension, the rear end of energy-absorbing box body and stringer pairing.That is the lateral surface relative inner face gradient angle a of energy-absorbing box body is
30 °~60 °, i.e. the medial surface of energy-absorbing box body is parallel with stringer 6.It is arranged two in the lateral surface rear positions of energy-absorbing box body
Reinforcing rib 2-1, reinforcing rib prevent collision initial stage, and crumple deformation in energy-absorption box bottom guarantees crumple sequence.Each energy-absorbing box body is close
Forward position is provided with a circumferential crumple guiding groove 2-2, and crumple guiding groove is for guiding the crumple of energy-absorption box front when colliding.
Referring to Fig. 4 energy-absorption box of the present invention, opposing side rails are to wheel direction deflection, during small offset collision and wall
The registration of barrier 5 is higher, and energy-absorption box energy-absorbing effect is good, is conducive to impact force being effectively transferred to stringer, so as to improve stringer
Crumple form reduces damage of the small offset collision to occupant.Compared to existing energy-absorbing box structure shown in fig. 5, energy-absorption box axis with
Stringer essentially coincides, low with the registration of obstacle during small offset collision, and when collision is difficult to for impact force being effectively passed to
Stringer causes vehicle energy-absorbing insufficient, and Impact energy is transmitted to crew module, damages to occupant.
The above-mentioned description to energy-absorption box front, back, inside, outside direction is depending on energy-absorption box use state.
