Abstract
The utility model discloses an energy absorber used for an automobile collapsing area, which comprises a front end fixing plate and a back end fixing plate, wherein a plurality of energy absorbing plates are arranged between the front end fixing plate and the back end fixing plate; a plurality of weak cross sections which are orderly arranged from front to back and have different sizes are arranged on each energy absorbing plate; the weak cross sections of each energy absorbing plate are lightly folded; and one partition board is inserted in every one folding. The utility model can fully coverts the impact energy into plastic deformation energy and a small amount of heat energy without influencing a cab and a back row region, so people in the automobile can avoid the injury or only has light injury.
Description
Technical field
The utility model relates to a kind of energy absorption device, especially a kind of energy absorption device that is used for the automobile crumple zones.
Background technology
Meet with bump at automotive front end at present, for preventing unlikely cockpit and the back row district of bringing disaster to of its bump crumple, in technological improvement, only be conceived to make great efforts to improve the rigidity aspect of automotive front end crash bar and vehicle frame, the impact detection standard formulated of national governments for this reason about vehicle safety performance, its head-on crash speed per hour only be 50 kms/hour, in recent years Ou Mei some professionals auto against speed per hour of organizing NCAP to formulate be increased to 64 kms/hour, this detect to require but can reach, and also has only indivedual vehicles of minority automaker.This shows, when automobile meets with high-speed crash, the protection that can not furnish personal security of its car body.
The utility model content
The purpose of this utility model is to provide a kind of energy absorption device that is used for the automobile crumple zones that can effectively prevent impaction lesion.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of energy absorption device that is used for the automobile crumple zones, comprise front end adapter plate and rear end adapter plate, arrange between front end adapter plate and the rear end adapter plate some energy-absorbing plates are installed, the a plurality of fragile cross section that every energy-absorbing plate is provided with and varies in size, arrange in regular turn by front and back, the fragile section of every energy-absorbing plate has slight bending, on each energy-absorbing plate, every the interspersed a slice dividing plate of a bending.Per two of described energy-absorbing plate is one group, and their wrap direction is opposite.
Per two of described energy-absorbing plate is one group, and pairing wrap direction is opposite.
The utlity model has following beneficial effect:
(1) can be with the function of automobile impacting, its overwhelming majority and even all in crumple zones is absorbed by the multistage plastic bending distortion of multi-disc energy-absorbing plate, even bump kinetic energy changes the heat energy that plastic deformation ability and distortion produce into.
(2) make present rigid collision become the flexibility collision of buffering form; the correlation intensity index of automobile design also can be fully satisfied in the design that passes to the impulsive force of crash bar and vehicle frame simultaneously; thereby when automobile meets with bump; the unlikely cockpit that brings disaster to of its bump crumple has been guaranteed the safety guard-safeguard of car body to the person.
(3) the utility model volume is little, and is in light weight, is installed in the crumple zones, do not influence ventilation and heat, also need not change car conour, reliable and stable in travelling.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1-front end adapter plate, 2-rear end adapter plate, 3-dividing plate, 4-energy-absorbing plate.
The specific embodiment
As shown in Figure 1, a kind of energy absorption device that is used for the automobile crumple zones, comprise front end adapter plate 1 and rear end adapter plate 2, arrange between front end adapter plate 1 and the rear end adapter plate 2 eight energy-absorbing plates 4 are installed, the a plurality of fragile cross section that every energy-absorbing plate 4 is provided with and varies in size, arrange in regular turn by front and back, the fragile section of every energy-absorbing plate 4 has slight bending, on each energy-absorbing plate 4, every the interspersed a slice dividing plate 3 of a bending; Energy-absorbing plate 4 per two be one group, and pairing wrap direction is opposite.
When front end adapter plate 1 is subjected to clashing into, each energy-absorbing plate 4 bending in regular turn and crumple, every dividing plate 3 moves in regular turn backward, makes Impact energy all change the plastic deformation ability and the small amount of thermal energy of energy-absorbing plate 3 into, and unlikely cockpit and the back row district of bringing disaster to avoids the occupant or alleviates injury.
Claims (2)
1. energy absorption device that is used for the automobile crumple zones, it is characterized in that: comprise front end adapter plate (1) and rear end adapter plate (2), arrange between front end adapter plate (1) and the rear end adapter plate (2) some energy-absorbing plates (4) are installed, the a plurality of fragile cross section that every energy-absorbing plate (4) is provided with and varies in size, arrange in regular turn by front and back, the fragile section of every energy-absorbing plate (4) has slight bending, on each energy-absorbing plate (4), every the interspersed a slice dividing plate (3) of a bending.
2. the energy absorption device that is used for the automobile crumple zones according to claim 1 is characterized in that: per two of described energy-absorbing plate (4) is one group, and pairing wrap direction is opposite.
