Description

A kind of flat fronted car anticollision operator's compartment device

Technical field

The utility model belongs to various automotive safety technical fields, is the anticollision operator's compartment device that is particularly suitable for various large, medium and small automotive uses specifically.

Background technology

Growing along with vehicle, the automotive safety technology has obtained long term growth, existing various bumper/spoiler, buffer bumper, hydraulic damper, safety bounce-back air bag, and the anticollision device of machinery such as various energy dispersers or air bag, as China Patent No. be: 200420029176.1 disclosed a kind of vehicle anticollision energy dispersers, mainly comprise: be fixedly connected on the fixed mount on the automobile, the tressel movable side by side with fixed mount 1, wherein the interval on tressel is provided with and guides it along the reciprocating guide rod of fixed mount, guide rod is inserted in the fixed mount hole versatilely, and its end is equipped with the cone-shaped spring that tressel is resetted.

And for example China Patent No. is: 200620052482.6 disclosed a kind of vehicle anticollision devices, by good rigidly, crash bar that the material that intensity is high is made and crash bar sleeve and baffle plate are formed, sleeve is by being bolted to two crossbeam front ends of automobile, the crash bar front end stretches out the headstock forward position and is fixed with crashproof baffle plate, be provided with closed cavity between crash bar rear end and the sleeve tail-hood, spring is housed in the cavity, air and hydraulic oil, after auto against arrives hard thing, crash bar can slide backward, air in the fully enclosed cavity can play buffer action, reaches the purpose of anticollision.

And for example China Patent No. is: 03217701.1 disclosed a kind of being installed in is used to protect the device that automobile is collided on the automobile, it is made up of toroidal frame and anti-collision frame around automobile, the anti-collision frame is in the outside, its the inside is connected with toroidal frame elasticity, outer facade is furnished with the rolling springing, and the front and back of toroidal frame and anti-collision frame are triangle frame.

Because purposes, kind and the kind of automobile are a lot, though, the invention of anticollision device is a lot of at present, but many anticollision devices are bigger with the vehicle protection face that uses, for the variety classes automobile reason that crashes, the breakdown diagnosis how required safety device just can alleviate automobile and driver still is nowhere near, thereby, lack practicality mostly, also applied.

At present, to flat fronted car, particularly the tack autotruck bumps and small passenger car generation rear-end collision, often causes the driver and conductor to injure, and all is because operator's compartment generation gross distortion causes mostly.As shown in Figure 1, tack autotruck rear-end collision scheme drawing.Through long-term observation and a large amount of accident analysis, from passive safety feature, the major cause that this automobile bumps and rear-end collision causes the driver and conductor to injure has: existing flat fronted car anticollision safety device is for being close to operator's compartment or vehicle body bumper/spoiler, tack autotruck particularly, its container height after knocking into the back, causes the front bumper of flat fronted car inoperative, operator's compartment direct impact container, thereby directly cause driver and conductor's injury.Equally, this vehicle causes more serious serious accident after also causing many kinds of C-classs and other kinds to knock into the back.For this reason, we can say because existing various vehicle anticollision devices all are not suitable for the use of tack autotruck, thereby the load-carrying vehicle of this a large amount of uses is badly in need of a kind of collision prevention device that can prevent effectively that accident from taking place.Also have small passenger car and truck, rear-end collision often takes place with truck in small passenger car on the express highway, and the bumper/spoiler of car and the vehicle frame of truck are not collided and directly got into below the lorry vehicle frame.So far, this device does not still improve, and as the afterbody of crossing truck this device is housed, and small passenger car knocks into the back and will drive the air bag collision with the car of lorry, and the safety factor of chaufeur has just improved greatly like this.

Summary of the invention

The deficiency that the vehicle anticollision device that the purpose of this utility model provides at above existing automotive safety technology exists, a kind of large, medium and small automobile that is fit to is provided, particularly the tack autotruck uses, simple in structure, machinery and air bag combination can effectively prevent before and after the automobile the various large, medium and small vehicle anticollision device of collision mutually.

The technical solution of the utility model is achieved in that

A kind of flat fronted car anticollision operator's compartment device is the device that mechanical damping and air bag buffering combine, and it comprises mechanical damping and two parts of air bag buffering; It is characterized in that: described mechanical damping part: have before and after flat fronted car and the base of installing on the vehicle frame bottom girder, the portable beam that matches with it is housed in described base, portable beam is limited in the base by pressing plate; Described pressing plate is fixed by bolts on the base, and several springs are housed between described base and portable beam, and energy absorbent block also is housed on the described base; Described air bag buffer portion: be contained in portable beam outer air bag and air bag hold-down ring, described air bag hold-down ring covers behind the air bag and is fixed by bolts on the portable beam.

The utility model and existing vehicle anticollision device technique relatively, it is the device that a kind of mechanical damping and air bag buffering combine, and has that mechanical buffering reaction is fast, the air bag buffering absorbs the big advantage of energy.It is simple in structure, compact, can be divided into three sections and cushion, can efficiently and effectively the operator's compartment and the driver and conductor of protection automobile.Be applicable to various flat fronted cars,, particularly be suitable for using on the tack autotruck as motor omnibus.

Departure point of the present utility model is: at first emphasis is the safety that will guarantee operator's compartment, because have only the safety of operator's compartment, could guarantee the safety of the person, has asked position " patron saint " in other words just for every driver.
