The specific embodiment
Below in conjunction with accompanying drawing, the present invention will be further described:
A kind of passive security energy absorption device for all-loading coach body as shown in Figure 1, Figure 2, Figure 3, Figure 4, comprise and be first, second energy absorption device 3,4 that left and right directions is symmetrically welded on body framwork and connects body forward structure skeleton 1 and underframe of coach 2, first, second energy absorption device 3,4 is symmetrical arranged along the line of centers of vehicle commander's direction.
Further, the first energy absorption device 3 comprises main energy absorption device 5 and auxiliary energy absorption device 6, auxiliary energy absorption device 6 is arranged on the sidepiece of main energy absorption device 5, the main energy-absorbing induction groove 52 that main energy absorption device 5 comprises main fixed mount 51 and is connected with main fixed mount 51, the auxiliary energy-absorbing induction groove 62 that auxiliary energy absorption device 6 comprises device for fixing screen on headrest 61 and is connected with device for fixing screen on headrest 61, device for fixing screen on headrest 61 fixes with main fixed mount 51, main energy-absorbing induction groove 52 and auxiliary energy-absorbing induction groove 62 are connected with body forward structure skeleton 1 respectively, and main fixed mount 51 is connected with underframe of coach 2.The first energy absorption device 3 is identical with the structure of the second energy absorption device 4, no longer the second energy absorption device 4 is described at this.
Further, between main energy-absorbing induction groove 52 and main fixed mount 51, be connected by bolt and nut, between auxiliary energy-absorbing induction groove 62 and device for fixing screen on headrest 61, be weldingly connected, between main fixed mount 51 and device for fixing screen on headrest 61, be connected by bolt and nut.
Further, the position of auxiliary energy-absorbing induction groove 62 is lower than main energy-absorbing induction groove 52, and auxiliary energy-absorbing induction groove 62 is positioned at the side of main energy-absorbing induction groove 52.
Further, auxiliary energy-absorbing induction groove 62 is arranged two along vertical, and two auxiliary energy-absorbing induction grooves 62 are all connected with device for fixing screen on headrest 61.Main energy-absorbing induction groove is arranged one, and auxiliary energy-absorbing induction groove is arranged two.The reason that two auxiliary energy-absorbing grooves are set is: because main energy-absorbing groove only has one, and main energy-absorbing cell wall thick be 4-6mm; And the wall thickness of auxiliary energy-absorbing groove only has 1.5mm or 2mm, and auxiliary energy absorption device is to be about to by conquassation to the limit or the conquassation of main energy-absorbing groove to a certain extent time at main energy-absorbing groove, auxiliary energy absorption device provides auxiliary energy-absorbing simultaneously, because its wall thickness is smaller, if install one on one side, that does not have auxiliary energy-absorbing function substantially, so adopt the mode that designs two on one side, can play well auxiliary energy-absorbing effect by actv. so to a certain extent.
Further, two ends of main energy-absorbing induction groove 52 are respectively equipped with the connecting portion 53 being connected with body forward structure skeleton 1 and main fixed mount 51.
Further, main energy-absorbing induction groove 52 comprises hollow body 521 and the groove 522 along the circumferential setting of hollow body 521 outer walls, groove 522 is arranged along the even interval of length direction of hollow body 521, and the line of centers of the line of centers of groove 522 and hollow body 521 matches.The structure of auxiliary energy-absorbing induction groove 62 is identical with the structure of main energy-absorbing induction groove 52, no longer auxiliary energy-absorbing induction groove is described at this.
Principle of work of the present invention is as follows:
Bumping in a flash, will there is crumple in main energy-absorbing induction groove, thereby absorb the moment potential energy that collision causes, in the time of main energy-absorbing induction groove conquassation distortion, auxiliary energy-absorbing induction groove starts by conquassation, thereby reduces the deformation failure of main energy-absorbing induction groove, finally reaches good conquassation effect.By effective energy-absorbing of main energy-absorbing induction groove and auxiliary energy-absorbing induction groove; can significantly reduce the body distortion that vehicle body brings in the time being subject to enormous impact collision; the secondary backward acceleration well rigidity vehicle body being brought in energy-absorbing filters out; and suffered power is transmitted well and disperseed to the each portion of vehicle body; actv. has been protected the distortion of vehicle body, has protected chaufeur and passenger's safety.
The present invention is applicable to the body structure forming with little rectangular tube welding in all-loading coach, main energy absorption device and auxiliary energy absorption device are a part of structures of car load vehicle body, combine together with vehicle body, the structure front end of passive security energy absorption device is connected with body front wall, structure rear end and vehicle body a slice beam and run through anterior before sleeper be integrated, in the time that vehicle body bumps, except this safety apparatus structure is effectively energy-absorbing, little rectangular tube welding structure can participate in stress deformation simultaneously, final power can be spread all over to car load vehicle body, reach good flexible energy-absorbing, can effectively avoid the U-steel structure of the stronger rigidity of fall crossbeam type chassis body structure to cause the rebound injury of the quadratic acceleration bringing of vehicle body secondary collision.
Above-described embodiment is described the preferred embodiment of the present invention; not scope of the present invention is limited; design under the prerequisite of spirit not departing from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention, all should fall in the definite protection domain of the claims in the present invention book.
