Abstract
The invention discloses a safety air bag system at the tail of an automobile. The safety air bag system comprises an air bag mounting shaft which is parallel to a rear bumper beam, and air bag units arranged on the air bag mounting shaft, wherein supporting seats which are fixed to the rear bumper beam are separately arranged at two ends of the air bag mounting shaft; the air bag mounting shaft is a square shaft; a square hole allowing the air bag mounting shaft to be inserted and locked is formed in each of the supporting seats; air bag mounting pieces are arranged in the middle part of the air bag mounting shaft; a clamping groove of which the shape is matched with that of the square shaft is formed in the middle part of each of the air bag mounting pieces; and each of the air bag units is fixed to the corresponding air bag mounting piece, and is matched with the clamping groove of the corresponding air bag mounting piece to clamp and lock the air bag mounting shaft. According to the safety air bag system disclosed by the invention, the air bag mounting shaft is the square shaft, so that after being inserted into the supporting seats, the air bag mounting shaft does not rotate, after being clamped to the shaft through the clamping grooves, the air bag mounting pieces cannot rotate either, and extra mechanisms are not needed for limiting the rotation. The air bag units are easy to mount, and targeting is accurate after the air bag units are mounted, so that a good safety protecting effect can be guaranteed.
Description
Technical field
The present invention relates to a kind of Safe air bag system at tail of automobile.
Background technology
Air bag system is the protection system of a kind of passive safety, it with seat harness with the use of, Ke Yiwei
Occupant provides effective Anti-bumping protection.
When automobile crashes in the process of moving, various sensors respond, electronic controller action then, control
Gas generator processed starts.Gas generator receives pilot gas propellant after signal, produces a large amount of gas, makes gasbag in pole
Launch rapidly in the short time, in driver or the front portion of occupant, sidepiece or top form elastic air cushion, apparatus with shock absorbing,
Thus effectively protect human body head and chest, make it from injury or alleviate extent of injury.
The most existing automobile product appearance arranging air bag at afterbody, when two car generation rear-end impacts, rear car can
Hit on the air bag of front truck afterbody, to avoid two cars that fierceness collision occurs.Current tailstock air bag typically uses
Install axle be fixed at the periphery of rear bumper, current mounting structure also exist installation axle be difficult to location, gas bag unit stable
Spend inadequate problem.
Summary of the invention
For above technical problem, the present invention provides a kind of Safe air bag system at tail of automobile, and it installs easily location, surely
Determine to spend, it is ensured that good protection effect can be provided.
The present invention solves that its technical problem be the technical scheme is that
Safe air bag system at tail of automobile, installs axle including the air bag being arranged in parallel with rear bumper and is located at air bag peace
Gas bag unit on dress axle, air bag is installed the two ends of axle and is provided with the bearing for being fixed on rear bumper, the installation of described air bag
Axle is square shaft, and bearing is provided with installs, for air bag, the square opening that axle inserts and locks, and air bag is installed the middle part of axle and is provided with air bag
Installation sheet, the middle part of air bag installation sheet is provided with and the draw-in groove of square shaft form fit, and gas bag unit is fixed on air bag installation sheet
And with the card slot fit of air bag installation sheet, air bag installed axis clamping and lock.
As preferred embodiment, axle installed by described air bag is hollow structure, the installation site of its corresponding gas bag unit
Place is provided with control string holes, the control line of gas bag unit by control string holes enter air bag install in axle and through air bag install axle and
Outside controller connects.
The invention has the beneficial effects as follows: axle installed by the air bag of the present invention is square shaft, and it will not rotate after being inserted into bearing,
And air bag installation sheet can not be rotated after being clamped on axle by draw-in groove, it is no longer necessary to extra structure is defined rotating, gas
Capsule unit is easily installed, and after installation, orientation is accurately, it is ensured that can play good security protection effect.
Accompanying drawing explanation
It is further detailed with detailed description of the invention below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of air bag installation sheet of the present invention.
Accompanying drawing illustrates: 1-air bag installs axle, 2-bearing, 3-air bag installation sheet, 4-gas bag unit, 5-rear bumper, 6-card
Groove.
Detailed description of the invention
The air bag system of the present invention is applied at the afterbody of automobile, and when vehicle is knocked into the back, this system can be touched
Sending out, air bag opens automatically, prevents two cars from fierceness collision occurring.
Seeing figures.1.and.2, Safe air bag system at tail of automobile of the present invention includes that air bag installs axle 1, bearing 2, air bag installation
Sheet 3 and gas bag unit 4.Air bag is installed axle 1 and is arranged in parallel with rear bumper 5, and the quantity of bearing 2 is two, is respectively arranged on gas
The two ends of axle 1 installed by capsule, and the bottom of bearing 2 is fixed on rear bumper 5.
Axle 1 installed by air bag is square shaft, and bearing 2 is provided with square opening, and during installation, the two ends insertion side of axle 1 installed by air bag
In shape hole, and it is locked to make air bag install axle 1 by the screw in screw insertion square opening.The quantity of air bag installation sheet 3 can
To configure as required, can be such as one, two, three or more than.The middle part of air bag installation sheet 3 is provided with square
The draw-in groove 6 of shape shaft coupling, gas bag unit 4 is fixed on air bag installation sheet 3 and coordinates gas with the draw-in groove 6 of air bag installation sheet 3
Capsule is installed axle 1 and is clamped and lock, and the method for locking can arrange corresponding screw on the sidewall of draw-in groove 6 and installation axle 1, passes through spiral shell
Silk is locked.During work, when gas bag unit 4 is triggered, air bag can be inflated and open, and forms buffering at rear bumper 5
Band, prevents two cars from producing sharp impacts.
Connecting up for convenience, air bag is installed axle 1 and is preferably hollow structure, and the installed position of its corresponding gas bag unit 4 sets
Have control string holes, the control line of gas bag unit 4 by control string holes and enter in axle 1 installed by air bag and through air bag install axle 1 and
Outside controller connects.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, that is made any repaiies
