Automobile property loss and personal injury.When head-on crash occurs for automobile, the component being collided at first is bumper, traditional
Bumper is not able to satisfy the requirement of automotive safety in high velocity impact.When speed very it is high collide when, huge inertia force meeting
Make automobile head that serious deformation occur, is easy to produce biggish impact force, driver and passenger are damaged.Therefore one kind is needed
The buffer gear of buffer capacity when can reduce acceleration when collision, enhancing car crass, this mechanism can protect vehicle
Interior personnel protect the appearance of automobile not destroyed as far as possible simultaneously.
Summary of the invention
Aiming at the problem that above-mentioned prior art Shortcomings, the purpose of this utility model is to propose a kind of car crass three-level
Buffer unit can enhance acceleration when collision energy-absorbing ability, reduction car crass, can protect the peace of interior driver and passenger
Complete and protection automobile appearance.
To achieve the above object, the utility model provides a kind of car crass three-level buffer unit.A kind of car crass
Three-level buffer unit, it is characterised in that: by bumper, leaf spring, buffer spring, bump rubber, crash energy absorption equipment and
Automobile back rest composition.The crash energy absorption equipment includes dsah-pot, and the dsah-pot is fixed on the crossbeam of car, described
Dsah-pot front end stretch out piston mandril, the top of piston mandril is fixed on car insurance bar, and the buffer unit is by preceding
Latter two buffer set at, separated between the buffer area of front and back by fixing seal column, be provided on fixing seal column connection front and back
The through-hole of buffer area, the preceding buffer area include secondary piston, compressed spring and hydraulic oil, and the rear buffer area is living after including
The piston of rear buffer area described in plug, cushion pins and hold-down support composition is fixedly connected with hold-down support.
A kind of car crass three-level buffer unit, there are two the crash energy absorption equipments, is arranged symmetrically in bumper
The left and right sides, one end is just contacted with bumper in transverse direction, and the other end is connect with the automobile back rest.
A kind of car crass three-level buffer unit is connected to bump rubber behind the leaf spring, in buffering rubber
3-6 buffer springs are mounted with inside blob of viscose.
A kind of car crass three-level buffer unit, the piston and hold-down support of the rear buffer area pass through 4-6 bufferings
Pin connection.
A kind of car crass three-level buffer unit, the upper surface of described automobile back rest outside have welded 4-6 admittedly with following
Determine support.
A kind of effective income for car crass three-level buffer unit that the utility model uses is: behind bumper
It is mounted with crash energy absorption equipment, and is mounted with bump rubber behind leaf spring, when automobile collides, pass through steel
Flat spring, compressed spring and cushion pins three-level buffering energy-absorbing improve buffer capacity of the automobile in collision in this way, can reduce
Acceleration of the automobile in collision, can preferably protect the safety of interior driver and passenger.
Detailed description of the invention
Attached drawing 1 is a kind of overall construction drawing of car crass three-level buffer unit.
Attached drawing 2 is a kind of structure chart of the bump rubber of car crass three-level buffer unit.
Attached drawing 3 is a kind of structure chart of the crash energy absorption equipment of car crass three-level buffer unit.
In attached drawing: 1- bumper 2- leaf spring 3- bump rubber 4- crash energy absorption equipment 5- automobile back rest 6-
Dsah-pot 31- bump rubber 32- buffer spring 41- piston mandril 42- secondary piston 43- compressed spring 44- hydraulic oil
Piston 48- cushion pins 49- hold-down support after 45- through-hole 46- fixing seal column 47-
Specific embodiment
The utility model is further described with reference to the accompanying drawing.
Referring in attached drawing 1, attached drawing 2, attached embodiment shown in Fig. 3, a kind of car crass three-level buffer unit, by bumper
1, leaf spring 2, bump rubber 3, crash energy absorption equipment 4, the automobile back rest 5, dsah-pot 6, the crash energy absorption equipment 4 have
Two, it is arranged symmetrically in the left and right sides of bumper 1, one end is connected with bumper rigid 1 in transverse direction, the other end and automobile
The back rest 5 connects.
Bump rubber 3 described in attached drawing 2 is mounted on behind leaf spring 2, and 3-6 are installed inside bump rubber 3
A buffer spring 32.
Crash energy absorption equipment 4 described in attached drawing 3 include piston mandril 41, secondary piston 42, compressed spring 43, hydraulic oil 44,
Through-hole 45, fixing seal column 46, rear piston 47, cushion pins 48, hold-down support 49, the dsah-pot 6 are fixed on the crossbeam of automobile
On, dsah-pot 6 is provided with former and later two buffer areas, is separated between the buffer area of front and back by fixing seal column 46, fixing seal column 46
On be provided with the through-hole 45 of connection front and back buffer area, be provided with secondary piston 42, compressed spring 43 and hydraulic oil 44 in preceding buffer area,
Rear piston 47, cushion pins 48 and hold-down support 49 are provided in buffer area afterwards.Piston mandril 41 on secondary piston 42 is from dsah-pot
49 front end is stretched out, and the top of piston mandril 41 is fixed with bumper.
6 cross section of dsah-pot described in attached drawing 1 is circle.
Specifically, automotive front end bumper 1 generates deformation, and leaf spring 2 is to 1 energy of bumper when automobile collides
Enough play the role of shoring, generate and buffer for the first time, when impact force is excessive, 1 deformation of bumper is withstood forces more than leaf spring 2
When, external force can be forced through piston mandril 41 and secondary piston 42 passes to the compressed spring 43 in preceding buffer area, generate second
Secondary buffering, when impact force is bigger, the hydraulic oil 44 in preceding buffer area is entered in rear buffer area by through-hole 45, passes through rear piston 47
Hold-down support 49 is squeezed, cushion pins 48 are cut, third time is generated and buffers, by buffering three times, alleviate impact force significantly, subtract
The impact force of automobile, the safety of effective protection people and automobile are lacked.
