Description
Technical field
The utility model patent is related to automobile safety protective technical field, is a kind of car crass suction with gradient-structure
It can box.
Background technology
With economic continuous development, the improvement of people's living standards, it is essential that automobile is increasingly becoming people's trip
The vehicles, however big and small various traffic accidents occur again and again, the huge injury of the life and property band to people
With loss, therefore, the safe design problem of automobile becomes each automobile industry focus of attention.
Most of automobiles when crashing, huge impact kinetic energy entrained by vehicle mainly by vehicle foreside or
The plastic deformation of person rear portion metal structure absorbs, to protect vehicle body grid beam without damage and the safety of the protection occupant person.
The essence of car crass is exactly the large deformation endergonic process of walled metallic structure, and wherein energy-absorption box is exactly main energy absorbing component,
It is securing member important in bumper system for vehicles, be mounted on automobile front longitudinal beam or floor side member and bumper beam it
Between, energy caused by collision is absorbed by the plastic deformation of energy-absorption box when colliding, protects vehicle body frame as far as possible
Beam is without damage, to protect the personal safety of occupant, reduces the rehabilitation cost of vehicle.
Traditional energy-absorption box mostly uses greatly the rectangular homogeneous texture of four sides plate body, which can inhale in automobile collision procedure
Receive certain collision energy, but due to using simple equal wall thickness homogeneous texture, overall structure is almost simultaneously in collision process
Into the plastic stage, absorption energy is relatively low and energy absorption ability waste is serious.Simultaneously because collapse energy-absorption process is in simple linear
Variation, it is obviously insufficient for the protective capacities of the collision process such as complicated collision, secondary collision.
For this problem, the present invention proposes a kind of gradient-structure energy-absorption box.The energy-absorption box is along main collision course material thickness
Degree changes in gradient, and this aspect can enter the difference of plastic period by controlling each position of energy-absorption box, effectively be promoted
Energy absorption ability, while the material integral stiffness for just brushing up against side impact direction is promoted by wall thickness change, complexity can be significantly improved and touched
The protective capacities for hitting secondary collision has great importance and is worth for promotion automotive safety.
Invention content
In order to overcome the problems, such as that existing energy-absorption box absorbs little energy, to the protection deficiency of complicated and secondary collision etc., originally
Utility model patent proposes a kind of energy-absorption box with gradient-structure.Energy-absorption box becomes in gradient along main collision course material thickness
Change, effectively promote energy absorption performance, while significantly improving the protective capacities for complicated collision and secondary collision, by being inhaled to collision
The raising of energy ability realizes that driver and passenger drive the promotion of safety.
The technical solution adopted by the utility model to solve its technical problems is that：4 kinds of identical material different-thickness of selection
Energy-absorption box metal material, plate thickness are respectively 1.0mm-6.0mm.With 1/4 height of energy-absorption box and Zhou Changwei parameter blankings, by metal
It is energy-absorption box perimeter that material, which is respectively cut as length, is highly 1/4 height billot of energy-absorption box.Billot is folded by bullodozer
Square is hollow cell type by electric arc welding.By the hollow cell type part of four different-thickness, thickness is pressed successively from top to bottom
It arranges and integrally welded, is formed and become wall thickness energy-absorption box structure.
The specifically techniques such as the cutting preparation, bending process of metal material involved in manufacturing process, assembly welding.
One：Metal material is cut.In conjunction with Service Environment, the energy-absorption box metal that plate thickness is respectively 1.0mm-6.0mm is chosen
Material.According to energy-absorption box geometric dimension and design requirement, it is energy-absorbing that the plank of different wall thickness is cut into length respectively with plate shearing machine
Box perimeter, the highly billot for 1/4 height of energy-absorption box.
Two：Bending machining.Billot is subjected to the quartering as unit of equal length, it will be golden with bender at each Along ent
Belong to billot 90 ° of bending at same direction, the identical rectangular box of the length of side is made, and be structure as a whole by electric arc welding.
Three：Assembly welding.By 4 different cell type parts of thickness, along short transverse, sequence assembling from thin to thick is pressed respectively
Be welded as a whole structure, completes the processing for becoming wall thickness gradient energy-absorption box.
The advantages of the utility model patent, is：Simple in structure, easy to make, stability is good, significantly improves energy-absorption box
Energy-absorbing is horizontal and complexity is collided and the energy absorption ability of secondary collision.
