Referring to Fig. 1 to Fig. 5, fluid pressure type highway anticollision device, collision-prevention device 60 of the present utility model can comprise: be installed on a plurality of hydraulic pressure energy-absorbing assemblies 80 and Crashworthy plate 61 on the basis 62, hydraulic pressure energy-absorbing assembly 80 further comprises cylinder body 82 and has the piston 83 of gathering sill 83a, piston 83 can be made hollow shape, its front end at cylinder body 82 can dispose the seal 83b with the inwall 82a sliding-contact of cylinder body 82, certainly, the utility model also can be made piston 83 integral body.Dispose liquid 81 in cylinder body 82, liquid 81 preferred viscosityes are bigger and not volatile, as, hydraulic oil.Dispose at least one leakage hole 82b (this exemplary embodiment has disposed 5) near the bottom of cylinder body 82, on the leakage hole 82b on cylinder body 82 external surfaces, can dispose blocking piece 88, when piston 83 is subjected to a predefined force value, liquid 81 in the cylinder body 82 is opened blocking piece 88, and discharge from leakage hole 82b, for the liquid 81 that prevents to discharge sprays to the road surface, can also dispose reservoir 89 at the leakage hole 82b place of cylinder body 82 outsides.

When piston 83 moves down in cylinder body 82, liquid 81 is compressed, 5 blocking pieces 88 that be arranged on the leakage hole 82b this moment are forced out leakage hole 82b under the pressure effect of liquid 81,5 leakage hole 82b of cylinder body 82 bottoms have been opened, liquid 81 is drained in the reservoir 89 from leakage hole 82b, because the diameter of leakage hole 82b can be tiny,, that is to say that the mobile of piston 83 is slowly so liquid 81 is also little from the amount that leakage hole 82b discharges.Certainly, can pass through the quantity of the leakage hole 82b of increase cylinder body 82 bottoms, or the diameter of increase leakage hole 82b can change under identical active force the translational speed of piston 83 in cylinder body 82.

Certainly, the utility model can also be cancelled reservoir 89, changes the mode that the shutter (not shown) is installed at the leakage hole 82b place of cylinder body 82 external surfaces into and prevents that liquid 81 from spraying to the road surface.

One end has the V-arrangement conducting piece 84 that the first bending 84a and the other end have the second bending 84b, one of them support arm 84d of V-arrangement guiding element 84 is placed among the gathering sill 83a of piston 83, support arm 84d and gathering sill 83a are the α angle with respect to horizon, big or small preferred 30～60 degree at α angle, dispose installing hole 84c on the first bending 84a of V-arrangement conducting piece 84, installing hole 84c can pass through fixedly Crashworthy plate 61 of bolt 63, Crashworthy plate 61 preferred corrugated plate shape.Certainly, Crashworthy plate 61 of the present utility model can also be fixed on the first bending 84a by other mode; The second bending 84b of V-arrangement conducting piece 84 can be fixed on the reinforcement 90 on the cylinder body 82 by bolt 85; Certainly, the utility model can also pass through fixedly V-arrangement conducting piece 84 of other method, as, mode by welding is fixed on cylinder body 82 or its reinforcement 90, at this moment, support arm 84d can bring some pressure to bear through the liquid 81 in 83 pairs of cylinder bodies 82 of piston, makes liquid 81 be in the state of pressurization, forms an integral body with each parts that guarantees hydraulic pressure energy-absorbing assembly 80.Certainly, the utility model also can make liquid 81 be in the state of non-stress.

Between cylinder body 82 and piston 83, can dispose dust ring 86, drop in the cylinder body 82 to prevent rainwater and dirt.

The operating principle of this exemplary embodiment is described below.

Referring to Fig. 5 and Fig. 6, after vehicle collision fluid pressure type highway of the present utility model anticollision device, collision-prevention device, vehicle is given piston 83 to the impact force F of Crashworthy plate 61 (Fig. 1) by 84 conduction of V-arrangement conducting piece, piston 83 moves down at the inwall 82a of the effect lower edge of impact force F cylinder body 82, liquid 81 in the compression cylinder 82 also makes it produce a displacement (not shown) in cylinder body 82, because the bottom of cylinder body 82 disposes 5 leakage hole 82b, behind liquid 81 pressurizeds, blocking piece 88 is subjected to coming off behind the pressure of liquid 81, leakage hole 82b is unlocked, at this moment, liquid 81 is drained in the reservoir 89 from leakage hole 82b, again because the diameter of leakage hole 82b is more tiny, so liquid 81 is also little from the amount that leakage hole 82b discharges, that is to say that piston 83 is to move down with slower speed under the effect of impact force F.According to the momentum theorem in the physics: under identical collision mass and speed, prolong collision time and can reduce impact force.Therefore, in the compression process of liquid 81, Crashworthy plate 61 has produced the effect that retreats and cushion, and has prolonged vehicle and has acted on action time on the Crashworthy plate 61, has consumed the bump kinetic energy of vehicle, therefore, has reduced collision (reaction) power of 61 pairs of vehicles of Crashworthy plate; In addition, according to mechanics principle, because the gathering sill 83a along continuous straight runs on the piston 83 is a α angle, so the support arm 84d along continuous straight runs of placing in it also is a α angle, this α angle makes piston 83 conduction obtain decomposition for the reaction force on the V-arrangement conducting piece 84, the component F1 of vertical direction and the component F2 of horizontal direction have been formed, the F ' that makes a concerted effort to be of F1 and F2, F '=F in theory, so horizontal component F2 is significantly smaller than F, therefore, when Vehicular impact Crashworthy plate 61, the reaction force (based on F2) of 61 pairs of vehicles of Crashworthy plate will be significantly smaller than the power F of Vehicular impact Crashworthy plate 61, has protected the safety of vehicle effectively; In addition, because diameter and the quantity of leakage hole 82b are fixed, therefore, behind piston 83 pressurizeds in cylinder body 82 in the moving process, the active force of 81 pairs of pistons 83 of liquid is constant all the time, this just means that horizontal component F2 also is a constant, guaranteed that it also is a constant that Crashworthy plate 61 is given the reaction force of vehicle, the collision dynamics characteristic of further guaranteeing vehicle is near desirable impact curve, out of hand when avoiding collision happens, like this, energy absorption at hydraulic pressure energy-absorbing assembly 80, under the acting in conjunction of the plastic strain energy-absorbing of effect resolution of forces and Crashworthy plate 61 and V-arrangement conducting piece 84, can ensure the occupant safety in the accident vehicle effectively, reduce the damage degree of vehicle.

In sum; fluid pressure type highway anticollision device, collision-prevention device of the present utility model; decompose by the energy absorption of hydraulic pressure energy-absorbing assembly and the impact force of V-arrangement conducting piece; the deficiencies in the prior art have been overcome; when collision happens; protected passenger's safety effectively, the damage degree when also having reduced vehicle collision simultaneously.

Of the present utility model simple in structure, low cost of manufacture is convenient to maintenance, can be widely used in the anti-collision facility of various highways and road.

Exemplary embodiment that the utility model is above-mentioned and advantage only are typical examples, and it can not be considered as restriction of the present utility model.Description to the utility model exemplary embodiment is the scope that is used to illustrate rather than limit claim, and to those skilled in the art, clearly, the utility model also can be made multiple changes and improvements.
