Abstract
Automatic buffer bumper is made up of Wai Gang and interior thick stick, interior thick stick is fixed on the car body, between Nei Gang and the outer thick stick a plurality of energy dispersers are installed, energy disperser is made up of the inside and outside cylindrical shell and the spring of opening two one ends, inside and outside cylindrical shell open end is relative, inner cylindrical portion is inserted urceolus, the middle cavity that forms, spring places in the cavity, urceolus internal diameter and inner core external diameter are transition fit, make inside and outside cylindrical shell can endwisely slip and keep good air tightness, outer tube bottom has exhaust capillary, and the bottom of inside and outside cylindrical shell is separately fixed on the inside and outside thick stick.When collision happens, outer thick stick is clashed into inside thick stick and is moved, energy disperser is squeezed, the cavity internal gas pressure rises rapidly, pressurized air is discharged at a high speed by exhaust capillary, and the buffer generating shock damping action absorbs Impact energy, after crash situation disappeared, energy disperser automatically restored to extended configuration under the effect of spring.
Description
Technical field
The utility model relates to a kind of automatic buffer bumper.
Background technology
At present automobile becomes the requisite vehicle of people day by day, universal all the more along with automobile, and the traffic accident that is caused by automobile is also day by day seriously threatening mental awareness.When automobile bumps, the vitals that Federal bumper just becomes the protection navigating mate and alleviates damaged vehicle, and present automatic buffer bumper substantially all is the simple member of being made by sturdy material, the damage insurance thick stick absorbs the energy of bump during by bump, there is wretched insufficiency in such bumper/spoiler: when bump is fierce, bad bumper/spoiler of breaking absorbs the energy shortage of bump with the protection navigating mate, and navigating mate is come to harm easily; When bump was slight, bumper/spoiler still can be damaged, and brings unnecessary loss to vehicle.
The utility model content
The purpose that the utility model relates to is to provide a kind of automatic buffer bumper of protecting navigating mate and vehicle preferably.
The purpose of this utility model is achieved in that automatic buffer bumper is made up of Wai Gang and interior thick stick, interior thick stick is fixed on the car body, between Nei Gang and the outer thick stick a plurality of energy dispersers are installed, energy disperser is made up of the inside and outside cylindrical shell and the spring of opening two one ends, inside and outside cylindrical shell open end is relative, inner cylindrical portion is inserted urceolus, the middle cavity that forms, spring places in the cavity, both ends of the spring is fixedly mounted on inside and outside cylindrical shell bottom respectively, and urceolus internal diameter and inner core external diameter are transition fit, and cylindrical shell can endwisely slip and keeps good air tightness inside and outside making, outer tube bottom has exhaust capillary, and the bottom of inside and outside cylindrical shell is separately fixed on the inside and outside thick stick.Energy disperser does not stress at ordinary times, and spring makes energy disperser be extended configuration, when collision happens, outer thick stick is clashed into inside thick stick and is moved, energy disperser is squeezed, and the cavity internal gas pressure rises rapidly, and pressurized air is discharged at a high speed by exhaust capillary, the buffer generating shock damping action, absorb Impact energy, simultaneously, but spring also absorption portion Impact energy by compression, after crash situation disappeared, energy disperser automatically restored to extended configuration under the effect of spring.Collision takes place to such an extent that Shaoxing opera is strong; energy disperser is squeezed fast more; the air pressure that produces in the cavity is big more; shock damping action is strong more; the collision energy that absorbs is big more, can not offset whole collision energies even draft gear travel has compressed still, and energy disperser will be continued compression; by energy disperser inner/outer tube body deformability being destroyed further absorb collision energy, for navigating mate and vehicle provide further protection.
By implementing the utility model, can absorb the energy that auto against produces effectively, for navigating mate and vehicle provide excellent protection.
Description of drawings
Fig. 1 is the birds-eye view of automatic buffer bumper, and 1 is outer thick stick among the figure, the 2nd, and exhaust capillary, the 3rd, urceolus, the 4th, spring, the 5th, inner core, the 6th, interior thick stick.
The specific embodiment
The utility model is further described by the specific embodiment below in conjunction with accompanying drawing.Automatic buffer bumper is made up of outer thick stick 1 and interior thick stick 6, interior thick stick 6 is fixed on the car body, 4 energy dispersers are installed between interior thick stick 6 and the outer thick stick 1, energy disperser is had the urceolus 3 of opening by two one ends, inner core 5 and spring 4 are formed, inside and outside cylindrical shell open end is relative, inner core 5 parts are inserted urceolus 3, the middle cavity that forms, spring 4 places in the cavity, and spring 4 two ends are fixedly mounted on inside and outside cylindrical shell bottom respectively, and urceolus 3 internal diameters and inner core 5 external diameters are transition fit, inside and outside cylindrical shell can be endwisely slipped and keep good air tightness, urceolus 3 bottoms have exhaust capillary 2, and the bottom of urceolus 3 is fixed on the outer thick stick 1, and the bottom of inner core 5 is fixed on the interior thick stick 6.Energy disperser does not stress at ordinary times, and spring 4 makes energy disperser be extended configuration, when collision happens, outer thick stick 1 is moved by the inside thick stick 6 of bump, energy disperser is squeezed, and the cavity internal gas pressure rises rapidly, and pressurized air is discharged at a high speed by exhaust capillary 2, the buffer generating shock damping action, absorb Impact energy, simultaneously, but spring 4 also absorption portion Impact energy by compression, after crash situation disappeared, energy disperser automatically restored to extended configuration under the effect of spring 4.Collision takes place to such an extent that Shaoxing opera is strong; energy disperser is squeezed fast more; the air pressure that produces in the cavity is big more; shock damping action is strong more; the collision energy that absorbs is big more, can not offset whole collision energies even draft gear travel has compressed still, and energy disperser will be continued compression; by energy disperser inner/outer tube body deformability being destroyed further absorb collision energy, for navigating mate and vehicle provide further protection.
