Description

Buffer multi-function protective system and buffering guard rail

The present invention relates to a kind of self-propelled vehicle protection system and guard rail, more precisely, relate to a kind of buffer multi-function protective system and buffering guard rail when being used for self-propelled vehicle generation traffic accident.

Known self-propelled vehicle safety guard-safeguard air bag and guard rail; when crashing, can only implement among a small circle a protection to driving person; guard rail also is a kind of passivity fender guard of very stiff and demanding formula; a common drawback of above-mentioned two kinds of devices is exactly all can not alleviate and weaken the enormous impact force intensity of collision of motor-driven vehicles in the traffic accident, more can not give any protection by the side of hitting.

Task of the present invention is to create a kind of buffer multi-function protective system and buffering guard rail when being used for self-propelled vehicle generation traffic accident; when self-propelled vehicle crashes; can initiatively carry out actv. by the effect of buffer gear to the collision impulsive force alleviates and weakens; crashing by dead-man's device simultaneously, a collision enforcement is urgent brakes lastingly; thereby effectively reduce impulsive force to collision with by the impact load and the destruction of being collided, can prevent the generation of a series of repetitions such as driver's stupor causes in the accident slide ripple and subsequent faults simultaneously.

The method that solves task of the present invention is: the buffer multi-function protective system when being used for self-propelled vehicle generation traffic accident comprises anterior bumper, electric emergency hand brake (centre brake), posterior bumper.The recoil spring of energy disperser in-to-in buffer gear can select for use coil spring, air bellow, steel spring etc. to cooperate tube type hydraulic shock damper or oscillating rod type bumper, constitute because principle is identical with effect, sincerely select for use representative coil spring to cooperate the buffer gear that constitutes to describe with tube type hydraulic shock damper at this; Direct contact parts bump rubber when the energy disperser outer front end is provided with collision, bump rubber connects with the flexible piece of the impulsive force transferring elements of energy disperser, flexible piece connects with energy disperser in-to-in buffer gear, and impulsive force passed to buffer gear, buffer gear is made of many groups spiral recoil spring and tube type hydraulic shock damper, is made up of 1 spiral recoil spring and 1 tube type hydraulic shock damper for every group; Energy disperser is divided into forward and backward energy disperser (principle is identical) and is contained in self-propelled vehicle front and back bumper/spoiler front end respectively, also can be integrally manufactured with automotive frame; Energy disperser be used for self-propelled vehicle in the past or from after bump and when being hit accident, the impulsive force intensity that collision is produced cushions to be alleviated and weakens, when self-propelled vehicle crashes, the bump rubber of bumper for automotive vehicle energy disperser is contracted in energy disperser inside by the flexible piece of collision promotion, and collision impact power imposed on energy disperser in-to-in buffer gear, buffer gear utilizes the elastic buffer of many group spiral recoil springs and the fluid power of tube type hydraulic shock damper to alleviate characteristic and effect in stressed compression process, the impulsive force that vehicle collision is produced progressively relaxes and alleviates, and then actv. weakens and impacts collision and the quilt that intensity of force alleviates and reduce self-propelled vehicle and hit load; Many groups tube type hydraulic shock damper of buffer gear utilizes its hydraulic damping tension simultaneously, will play the prevention effect to the bounce after the buffering, and each mechanism is slowly restored to the original state; Electric emergency hand brake (centre brake) is when being used for collision happens, can initiatively automatically implement the device of emergency brake to vehicle, can prevent rear-end collision, and the driver goes into a coma and the slope takes place to slip weighs down paddy, continuously accidents and a back accident such as collision.Its mechanicalness deceleration and stopping performance is more reliable than other oil that is used for wheel braking gentle braking device of stopping, can avoid the oil gentle braking device of stopping that braking failure hidden danger and the shortcoming that oil, gas leakage cause takes place easily, the electric emergency hand brake is made up of to reach with hand brake crash sensor, delay control circuit, electrodynamic braking horse, the crash sensor circuit is connected with delay control circuit, time delay circuit is connected with electrodynamic braking motor circuit, and the electrodynamic braking motor connects with hand brake joystick pull bar by the pulling force tooth plate; When the collision happens accident, the flexible piece of energy disperser is oppressed the induction steel ball application of force that is arranged on the crash sensor in the energy disperser in interior compression process, respond to when contracting in the steel ball sensor and the conducting of brake motor control circuit, electric current is defeated by the electrodynamic braking motor, the electrodynamic braking motor gets electric back and starts, by the meshing of motor gear and pulling force tooth plate the pulling force tooth plate is spurred, the pulling force tooth plate spurs the hand brake pull bar that connects with it simultaneously, make hand brake implement emergency braking, time delay circuit cuts off the power supply of electrodynamic braking motor after 3 seconds, make motor stop work done, because drg had the long-term immobilization lock function originally, so vehicle is the long-term immobilization state, the operating mode of brake off is the same with the operating mode of common hand brake, only need press the snap close button of hand brake pull bar, put down pull bar and get final product.Described cushioning guard fence (automobile with) when being used for self-propelled vehicle generation traffic accident comprises protective frame, on put energy disperser, underlying energy disperser and back buffer device, on put energy disperser to be arranged on guard rail upper end be one with the guard rail frame, the energy disperser outside is provided with the flexible piece of buffering and connects with the inner buffer gear that is provided with of energy disperser, buffer gear is made up of a plurality of spiral recoil springs, is used to bear collision and to the buffering and the alleviation of impact force;
