Abstract
The utility model relates to a telescopic crash-proof bar bumper for vehicles, which is composed of crash-proof bars, a hydraulic telescopic and a spring bumper. Piston telescopic rods which are positioned in an oil cylinder body are symmetrically and orderly arranged between the front and the rear crash-proof bars of a vehicle. The cylinder body is connected to an impact bearing sliding beam; a bumper spring is arranged between the impact bearing sliding beam and a middle sliding beam; a bumper composed of a piston and the cylinder body is also arranged between the impact bearing sliding beam and the middle beam. The crash-proof bar of the utility model has definite buffering stroke, and is capable of bearing definite impact force. Consequently, when a rear-end collision occurs, the telescopic crash-proof bar bumper for vehicles can make impact damage to human body and the vehicles reduced to lowest degree.
Description
The utility model relates to the telescopic crash bar shock absorber of a kind of automobile.
Along with the continuous development of arteries of communication, the owning amount of automobile is also more and more many, and thing followed traffic accident is also increasing.Except the generation of adopting various measures with the minimizing accident, how in inevitable accident, to protect the loss of personal safety and minimizing property, also be an important thing that causes that people pay close attention to.Existing automobile design has crash bar; it is fixed on the vehicle frame; but there is not certain cushion stroke; can only when low speed accident collision, be used for protecting the be not hit impact of power of the vitals of automotive interior; do not have protection people's effect at all; therefore, when being collided, personal safety still comes to harm.Simultaneously, crash bar utilizes blastic deformation and reaches the buffering purpose, like this, reuses after the crash bar after the distortion that is hit also needs repairing again, and is pretty troublesome.Along with Freeway Development, the accident of rear-end impact happens occasionally on express highway, and accident is also quite serious, and therefore, it is important further that the safety of the person and automobile also seems.
The purpose of this utility model just provides the telescopic crash bar shock absorber of a kind of automobile, has certain cushion stroke, can bear certain impulsive force, thereby the impact injury that human body and automobile are subjected to drops to minimum level.
The technical solution of the utility model is: be made of crash bar, hydraulically extensible and hydraulic spring grease cup energy disperser, wherein symmetry is equipped with hydraulically extensible and hydraulic spring grease cup energy disperser between the crash bar before and after the automobile, its structure is: be connected with the piston expansion link with crash bar, the piston expansion link is positioned at cylinder body, cylinder body is connected and holds on sliding beam, recoil spring is housed holding between sliding beam and middle sliding beam.
According to technique scheme; at ordinary times; the front and back crash bar of automobile contracts in car chassis; when something unexpected happened; as long as the driver presses throttle; the moving piston expansion link of a thruster that hydraulic oil enters the cylinder body inner carrier outwards moves; thereby the crash bar motion reaches the outside of automobile before and after driving; when the head of automobile or tail are clashed into, at first bump against crash bar, impulsive force makes crash bar driven plunger expansion link promote to hold towards sliding beam compression recoil spring together with cylinder body; impulsive force is absorbed by recoil spring; not only reduced the damage of automobile, and protected the safety of human body, also exempted simultaneously because the trouble that crash bar is needed repairing by blastic deformation.After impulsive force disappeared, recoil spring recovered distortion, drove to hold towards sliding bar to promote cylinder body, and the piston expansion link resets crash bar, the conversion throttle, and hydraulic oil enters the opposite side of cylinder body inner carrier, promotes the piston reverses direction motion, makes crash bar again in the indentation car chassis.
The utility model is equipped with the energy disperser that is made of piston and cylinder body holding between sliding beam and middle sliding beam, and cylinder body is made of inside and outside cylinder body, and piston is positioned at inner cylinder body, is communicated with by oilhole between the inside and outside cylinder body.When being subjected to impacting, when holding towards the sliding beam compression spring, the driven plunger motion makes inner cylinder body inner carrier fwd hydraulic pressure flow in the outer cylinder body by oilhole, simultaneously, and again in the inner cylinder body with the hydraulic oil inspiration piston back in the outer cylinder body.When impulsive force disappears, when spring recovers distortion, hold towards sliding beam and make the piston reverses direction motion, hydraulic oil is slowly entered in the outer cylinder body by oilhole, produce impact with regard to having avoided owing to spring recovers distortion like this, thereby crash bar is resetted reposefully.
Therefore, the telescopic crash bar shock absorber of the automobile that the utility model provides modern design, rational in infrastructure; retractable; do not influence the attractive in appearance of automobile, easy to use, emergent use is fast and accurate; and has certain cushion stroke; can bear certain big impulsive force, rare distortion not only can protect car body to avoid impact failure; and can protect personal safety, especially in knocking into the back collision, express highway more can bring into play its preceence.
Below in conjunction with the embodiment description of drawings:
At first accompanying drawing is described:
Fig. 1 represents structural representation of the present utility model.
Referring to Fig. 1, design organic frame 1, on frame, have sliding tray, in the middle of being equipped with in the sliding tray sliding beam 2 and about hold towards sliding beam 3, at middle sliding beam 2 with hold towards between the sliding beam 3 cluster spring 5 and piston-type hydraulic buffer are housed, wherein piston 6 is connected and holds on sliding beam 3, cylinder body 7 is connected with middle sliding beam 2, inner cylinder body 8 is housed in the cylinder body 7, and piston 6 is positioned at cylinder body 8, and inside and outside cylinder body 7,8 is communicated with by oilhole 9.Hydraulic telescopic device is housed holding between sliding beam 3 and forward and backward crash bar 11, is made of piston 4 and oil cylinder 10, piston 4 is connected on the crash bar 11, and oil cylinder 10 is connected with holding towards sliding beam 3.Cylinder body 7 and oil cylinder 10 all are connected with car hydraulics by oil pipe.The driver can pass through operated valve, makes the air compressor work on the automobile, by oil pump, makes hydraulic oil in oil pipe enters cylinder body 7 and oil cylinder 10, makes crash bar flexible with driven plunger 4, and the effect of buffering protecting against shock is played in piston 6 motions.
