Abstract
The utility model relates to an anti-collision safety protector for vehicles, which is composed of two bumpers, a main touch wheel, a roller, a telescoping rod and a cylinder liner. The two bumpers, the main touch wheel and the telescoping rod are connected together by connecting shafts. The bumpers can form a herringbone or line shape when the telescoping rod expands or retracts. When the utility model is longitudinally impacted with other vehicles or fixtures, the longitudinal impact can be released in order to avoid the longitudinal extrusion caused by vehicle impact. The utility model can effectively protect the safety of a vehicle and passengers.
Description
One, technical field:
The utility model relates to a kind of vehicle collision safety hedging fender guard.
Two, background technology:
Along with expanding economy, vehicle especially automobile to have become people's life essential.Because the speed of automobile is fast, flow is big, and traffic accident is difficult to avoid.In order to alleviate the loss of accident, existing vehicle, particularly automobile all are equipped with safety device.As bumper/spoiler, safety air bag or the like.Though these measures can be played some protective actions, all be passive protection.
Three, summary of the invention:
The purpose of this utility model is to provide a kind of vehicle collision safety hedging fender guard.When collision was inevitable, initiatively hedging decomposed the impulsive force that slows down vertical high-speed crash, the vertical extruding when preventing vehicle collision, protection vehicle and occupant's safety.
The technical solution of the utility model is: a kind of vehicle collision safety hedging fender guard, it is characterized in that: form by risk-avoiding bar, main colliding wheel, roller, main expansion link, secondary expansion link and cylinder sleeve, risk-avoiding bar is two, and an end of two risk-avoiding bars is associated in its hinge together by adapter shaft; Adapter shaft is provided with main colliding wheel; Its adapter shaft also is connected with an end of main expansion link, and the other end of main expansion link is connected with cylinder sleeve; On two risk-avoiding bars, be provided with roller; The outer end of two risk-avoiding bars flexibly connects with secondary expansion link respectively.
The utility model is arranged on the front end of vehicle, and also the rear and front end all is provided with as required.When vehicle ', can start expansion link, risk-avoiding bar is chevron pointing stretches out, can risk-avoiding bar is shrunk to in-line and be built in the decoration baffle that spring is housed by expansion link after the parking.
The utility model is owing to be risk-avoiding bar the chevron pointing setting in motion, and on risk-avoiding bar, be provided with roller, in case bump, at first bump is the main colliding wheel at chevron pointing tip, can bump against at an angle generally speaking, thereby exert all one's strength and decompose, can deflect then touches risk-avoiding bar on one side, because risk-avoiding bar is provided with roller, impact is disperseed, make impact become force of rolling friction, thereby alleviate the loss that collision brings greatly, prevent the generation of serious accident.
Four, description of drawings:
Fig. 1 is arranged on the structural representation at vehicle two ends for the utility model;
Fig. 2 looks scheme drawing for the risk-avoiding bar master;
Fig. 3 is Fig. 2 schematic top plan view;
Fig. 4 looks scheme drawing for Fig. 2 left side;
Fig. 5 is an expansion link form of a utility model scheme drawing;
Fig. 6 is the collision scheme drawing;
Fig. 7 is the power analysis chart.
Among the figure: 1, risk-avoiding bar; 2, main colliding wheel; 3, roller; 4, main expansion link; 5, secondary expansion link; 6, cylinder sleeve; 7, sleeve.
Five, the specific embodiment:
As shown in Figure 1, the utility model is made of risk-avoiding bar 1, main colliding wheel 2, roller 3, main expansion link 4, secondary expansion link 5 and cylinder sleeve 6.Risk-avoiding bar is provided with row's roller, one end of two risk-avoiding bars is associated in its hinge together by adapter shaft, and main colliding wheel is located on the adapter shaft, and adapter shaft also links to each other with an end of main expansion link, the other end of main expansion link stretches in the cylinder sleeve, is connected with secondary expansion link by chute on two risk-avoiding bars.
As shown in Figure 5, the utility model also can be made the form of having only an expansion link, and an end of its two risk-avoiding bar is connected with expansion link with main colliding wheel by adapter shaft, and the other end of two risk-avoiding bars stretches into sleeve, and sleeve is connected with vehicle by hinge.
That cylinder sleeve of the present utility model adopts is pneumatic, hydraulic pressure or electronic mode are operated.
During use, main expansion link is stretched out, make two risk-avoiding bars be the chevron pointing setting, can two risk-avoiding bars are in-line and be built in the vehicle decorative baffle plate by expansion link when not using.
Be example with vehicle and the collision of highway revetment below, carry out the analysis of exerting oneself.
As shown in Figure 6, F
DashTo act on guardrail by main colliding wheel, because direction and guardrail that car impacts are a fixed inclination, F

HitEqual and opposite in direction becomes the α angle with car axial.F
HitSize depend on F
DashSize.If it is static that vehicle becomes after a bit with speed V bump, the kinetic energy of automobile then all becomes impact energy at this point, and suffered impulsive force also just greatly.Because bumping and taking turns the friction force that is subjected to is its tangential direction, bumping wheel will rotate.After bumping wheel and rotating, the force that acts on mutually with guardrail and the action direction of power all change thereupon, and α contends cumulative big.Because the rolling of bumping wheel, the point of action of power and the action direction of power immediately change, so the momentum that collision causes is dissolved instantaneous minute momentum for different point of actions and different action directions, thereby collision impact obtains decomposing.
When vehicle and vehicle collision, if two cars all are equipped with the hedging fender guard collaborative decementation is then arranged.
