Abstract

The present invention relates to a kind of car crass three-level buffer units, it is made of bumper, leaf spring, buffer spring, bump rubber, crash energy absorption equipment and the automobile back rest, there are two the crash energy absorption equipments, it is arranged symmetrically in the left and right sides of bumper, one end is just contacted with bumper in transverse direction.Bump rubber is connected to behind leaf spring.When automobile collides, automotive front end bumper is deformed, and leaf spring, which plays bumper, to be shored, and is acted on first-level buffer has been collided.When impact force is excessive, external force can be forced through piston mandril and piston passes to compressed spring, act on level 2 buffering has been collided.When impact force is bigger, cushion pins can play three-level buffering energy-absorbing function after cutting.A kind of car crass three-level buffer unit of the invention can be buffered repeatedly when automobile is by severe crash, improve the impact energy of automobile, while also improving safety guarantee to occupant.

Description

A kind of car crass three-level buffer unit
Technical field
The present invention provides a kind of car crass three-level buffer units, belong to car protective device technical field.
Background technique
Automobile is early due to its is convenient, fast to have become the vehicles closely bound up in people's life.Currently, with automobile The rapid growth of ownership and the continuous improvement of car speed result in automobile collision accident rate and rise year by year, effectively cause 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 the present invention is to propose to a kind of car crass three-level bufferings Device, can enhance collision energy-absorbing ability, reduce car crass when acceleration, can protect interior driver and passenger safety and Protect the appearance of automobile.
To achieve the above object, the present invention provides a kind of car crass three-level buffer units.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, and described is slow It rushes cylinder front end and stretches out piston mandril, the top of piston mandril is fixed on car insurance bar, and the buffer unit is by front and back two A 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 buffering The through-hole in area, the preceding buffer area include secondary piston, compressed spring and hydraulic oil, the rear buffer area include rear piston, The piston of rear buffer area described in 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 present invention uses is: installing behind bumper Crash energy absorption equipment, and bump rubber is mounted with behind leaf spring, when automobile collides, pass through steel plate bullet Spring, compressed spring and cushion pins three-level buffering energy-absorbing improve buffer capacity of the automobile in collision in this way, can reduce automobile Acceleration 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 invention will be further described below in conjunction with the accompanying drawings.
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.
