Abstract
The utility model relates to an anti-collision device for vehicle which is composed of a cylinder body, a cylinder cover, a piston, a piston rod, and a fuel injection one-way valve. The space of the cylinder body of the lower part of the piston is a chamber with oil, and the upper part is a chamber without oil. The chamber with oil is communicated with the chamber without oil by a T-shaped oil path hole opened in the piston. The upright hole of the T-shaped oil path hole is provided with the fuel injection one-way valve. The piston is provided with an exhaust hole which is sealed by a seal element. The utility model adopts the impact force generated by the collision of the vehicles to act on the piston rod, the piston is driven to move, and the fuel injection one-way valve is opened. The oil in the chamber with oil flows into the chamber without oil to reach the goal of supporting and absorbing the impact force. The utility model has the advantage of simple structure, convenience, and practicality.
Description
The utility model relates to a kind of power actuated vehicle anti-collision device, belongs to the buffer technology field of bearing and absorbing the vehicle collision impact.
Existing power actuated vehicle anti-collision device all has baroque shortcoming, even as Chinese patent (patent No. 872144291) disclosed " Vehicular impact power relieving apparatus ", also, caused the difficulty in the use by touching part, impact absorption plant, cutting off several parts of vehicle clutch apparatus and forms.
The purpose of this utility model is to provide a kind of simple in structure, convenient and practical power actuated vehicle anti-collision device at above-mentioned deficiency of the prior art.
The purpose of this utility model realizes with following technical scheme: be installed on the power actuated vehicle anti-collision device on vehicle front bumper/spoiler and the keel beam, by cylinder body 9, cylinder cap 14, piston 5 in the cylinder body 9, oil spout check valve on piston rod 2 and the piston 5 is formed, wherein, space in the cylinder body 9 of piston 5 bottoms is for there being grease chamber 10, the space on its top is no grease chamber 13, there is grease chamber 10 to be communicated with by the T shape oil circuit hole of offering in the piston 5 with no grease chamber 13, on the vertical core 8 in T shape oil circuit hole the oil spout check valve is housed, in case collision happens, act on the piston rod 2 by bumper/spoiler, driven plunger 5 moves down, under pressure, the oil spout one-way valve opens has the oil in the grease chamber 10 to go into not have grease chamber 13 by T shape oil circuit orifice flow, thereby plays the effect of bearing and absorbing impact.Also have on the piston 5 one with the deflation hole 11 that has grease chamber 10, no grease chamber 13 to communicate, sealing member 12 sealing is arranged on the deflation hole 11, when needs keep in repairs cylinder body 9 inner component dismounting, unclamp sealing member 12, made formation normal pressures in the grease chamber 10, dismounting is very convenient, practical.
Described oil spout check valve is made up of valve seat 6, valve ball 7, spring 4, and valve seat 6 thread connection are on vertical core 8.
Sealing member 12 on the deflation hole 11 adopts simple screw sealing to get final product.
Extend an erecting stage 15 on the periphery of cylinder body 9, offer four screw thread shrinkage pools 16,18,19,20 on the erecting stage 15, cylinder body 9 is fixed on the vehicle keel beam by four screw thread shrinkage pools 16,18,19,20.
Also offer a groove 17 on the erecting stage 15, groove 17 is built-in with a block plate 21, and steel plate 21 is fixed on the vehicle keel beam.The bigger impulsive force that the purpose of offering groove 17 and setting up steel plate 21 forms when being to prevent vehicle collision cuts off the hold-down bolt in four screw thread shrinkage pools, and simultaneously, steel plate 21 can bear and absorb the impulsive force that a part forms cylinder body 8 again.In addition, can also adopt groove 17 to be built-in with the equivalence design of leaf spring.
The top of piston rod 2 is fixed on the vehicle front bumper/spoiler by flange 1, and is simple and practical.
The utility model is simple in structure, and is convenient and practical, and through test, the maximum impact that cylinder body can bear is 8369.8 tons, and buffering is than being 1: 56, and slack time is 147.76 times, can play anti-buffer action effectively.
Fig. 1 is the utility model structure diagram.
Fig. 2 is the cross-sectional of cylinder body.
Fig. 3 is that the c of Fig. 2 is to view.
Fig. 4 is the right elevation of Fig. 2.
The utility model is described in further detail below in conjunction with drawings and Examples.
The utility model is made up of the oil spout check valve on disc solid piston 5, piston rod 2 and the piston 5 in cylinder block 9, cylinder cap 14, the cylinder body 9, cylinder cap 14 and cylinder body 9 thread connection, and with cylinder body 9 sealings.The space of cylinder body 9 inner carriers 5 bottoms is for there being grease chamber 10, the space on its top is no grease chamber 13, there is grease chamber 10 to be communicated with by the T shape oil circuit hole in the piston 5 with no grease chamber 13, the cross-drilled hole 3 that promptly communicates with no grease chamber 13 reaches and cross-drilled hole 3 and the vertical core 8 that has grease chamber 10 to communicate, the oil spout check valve is housed on the vertical core 8, and the oil spout check valve is made up of valve seat 6 and the valve ball 7 in the valve seat 6, spring 4 of thread connection on vertical core 8.Offer on the piston 5 and the deflation hole 11 that has grease chamber 10, no grease chamber 13 to communicate, deflation hole 11 is a tapped bore, and the screw sealing is arranged on it.
Installation of the present utility model is respectively piston rod 2 tops and cylinder body 9 to be fixed on vehicle front and the keel beam.The top of piston rod 2 is fixed on the bumper/spoiler by flange 1, extend an erecting stage 15 on the periphery of cylinder body 9, offer four screw thread shrinkage pools 16,18,19,20 on the erecting stage 15, cylinder body 9 is fixed on the crossbeam by four screw thread shrinkage pools, and, offer parallel channels 17 on the erecting stage 15, it is spacing in addition that groove 17 is built-in with a block plate 21, and steel plate 21 is fixedly welded on the crossbeam.
