Description
Technical field:
The present invention relates to a kind of a kind of automobile collision active protection buffer device that prevents auto against protection usefulness.
Background technology:
Domestic and international at present safety device about auto against, mostly detect safety distance with microprocessor, remind the chaufeur brake or force brake, or stretch out on a small quantity at a slow speed by thick stick before the oil hydraulic motor control, but they all have a general character deficiency, and that is exactly the ability that lacks moment processing accident.
Summary of the invention:
The purpose of this invention is to provide a kind of automobile collision active protection buffer device; this device utilizes existing radar and microcomputer technology; can be before collision time a few tens of milliseconds eject fast; reach the most quick, increase the buffer distance of auto against to greatest extent; can effectively protect automobile and passenger's safety, it has solved the problem that lacks moment processing accident ability that exists in the prior art.This device is located on the thick stick of back, can also effectively prevent to knock into the back, and plays the effect that increases buffer distance.
The technical solution adopted for the present invention to solve the technical problems is: the main energy disperser of a kind of automobile collision active protection buffer device, microprocessor, gas generator and radar sensor constitute promptly by spacing steel wire, damper cover, spring, annular piston, energy disperser, pipe in the energy disperser, the piston draw-in groove, microprocessor, radar sensor, pipe in the lengthening, the buffering connecting rod, buffering connecting rod position-limited trough, buffering connecting rod limiting device, gas generator, aie escape valve, the spacing jump ring of O type piston, relief hole, fuel feed hole, the bumper/spoiler skeleton, pipe lid in the lengthening, oil sealing is formed; Spacing steel wire is squeezed between buffering connecting rod limiting device and the damper cover, damper cover is threaded with energy disperser, in the gas generator load buffer, spring is squeezed between the annular piston and gas generator of energy disperser front portion, pipe sliding block joint in annular piston and energy disperser, the energy disperser, the spacing jump ring of O type piston is connected with the annular piston draw-in groove, in energy disperser, be provided with the piston draw-in groove on the pipe, manage in the lengthening and the interior pipe of energy disperser, the interior pipe of buffering connecting rod and buffering, the interior pipe of lengthening and buffering connecting rod are sliding block joint; The pipe lid is bolted connection with the interior pipe that extends in pipe in radar sensor and bumper/spoiler skeleton, buffering connecting rod and bumper/spoiler skeleton, buffering connecting rod limiting device and the lengthening, aie escape valve and energy disperser, the lengthening; Microprocessor is that wire harness is connected with radar sensor, gas generator; In energy disperser, be provided with 10-30 relief hole and fuel feed hole in the pipe.Principle of work of the present invention is: utilize existing radar and microcomputer technology in time to monitor the relative velocity of two cars or car and obstacle; light gas generator before calculating the safety distance of will bump (or knocking into the back); make annular piston quick travel and promote hydraulic oil and flow to by fuel feed hole and manage in the energy disperser to the right; promote pipe in buffering connecting rod and the lengthening; thereby the bumper/spoiler skeleton is ejected rapidly; increase the buffer distance of water bumper; move right rightmost and fuel feed hole blocked of annular piston simultaneously; the spacing jump ring of O type piston just is stuck in and stops annular piston to be moved to the left in the piston groove; during vehicle collision; hydraulic oil is managed by a plurality of relief hole pressure releases in energy disperser; play buffer action; thereby reduce the intensity of auto against to greatest extent; reach effective energy-absorbing; reach the purpose of protection vehicle and passenger safety; realize soft collision; state when the state of this protection shock absorber in Fig. 1 is normal non-collision; when two cars or car and obstacle relative velocity are lower than setting speed; microprocessor will not ignited gas generator; at this moment hydraulic cushion distance is exactly the distance shown in Fig. 1 under the normality; what at this moment mainly lean on is the buffering of spring; in the time of the safety distance ignited less than design when the distance of two cars or car and obstacle; no matter relative velocity is much; all will not ignite gas generator; also do not light gas generator when preventing collision and cause secondary collision; also can prevent simultaneously meeting or closely beat radar sensor mistiming ignition gas generator fast with objects such as hammers; cause unnecessary loss; aie escape valve plays and prevents to crush energy disperser greatly owing to gas generator ignition back air pressure reaches among Fig. 1; can release air pressure rapidly after the impact of assurance thick stick skeleton in addition; when meeting collision, reserve enough pressure release spaces, play the purpose of buffering pressure release to hydraulic oil.Spacing steel cable plays the effect of pipe in the restriction lengthening among Fig. 1, pipe in preventing to extend is because inertia continues outside the ejection, buffering connecting rod limiting device is in buffering connecting rod At time of eject and the combined action of buffering connecting rod position-limited trough, prevent to cushion connecting rod and manage ejection in extending, damper cover and oil sealing play spacing and antisoiling effect; During use water bumper is fixed on the front and back crossbeam of automobile; radar sensor is contained on the bumper/spoiler skeleton; decide what and size of relief hole according to the different of tare and the design maximum speed upper limit; so that be applicable to different vehicles; microprocessor calculates the relative velocity and the relative distance of two cars or car and obstacle at any time by radar sensor; a few tens of milliseconds was ignited gas generator before monitoring was in time inevitably collided and taken place; the bumper/spoiler skeleton was ejected fast with the shortest time; reach the quickest; increase the buffer distance of auto against to greatest extent; effectively protection automobile and passenger's safety has improved people's traffic safety greatly.
The invention has the beneficial effects as follows; because a few tens of milliseconds was ignited gas generator before the present invention had adopted the inevitable collision of radar and microprocessing monitoring in time to take place; the bumper/spoiler skeleton was ejected fast with several milliseconds time; reach the quickest, increase the buffer distance of auto against to greatest extent, actv. protection automobile and passenger's safety has very big economic and social benefit.
