Abstract
The present invention relates to a kind of buffer device for collision of automobile, it is made of bumper, leaf spring, buffer spring, bump rubber, connecting rod and energy absorption device, there are two the energy absorption devices, it is arranged symmetrically in the left and right sides of bumper, one end is just contacted with bumper on horizontal direction, and the other end is connect with vehicle beam.It is connected to bump rubber behind leaf spring, 3-6 buffer springs are mounted with inside bump rubber, the connecting rod connection bump rubber and crash energy absorption equipment that leaf spring is installed below.When automobile collides, automotive front end bumper is deformed, and leaf spring, which plays bumper, to be shored, and is worked as a buffer to collision.Energy absorption device is installed behind bumper, plays the role of secondary buffer.The bump rubber that leaf spring is installed below can reduce that spring deflection is excessive, protect the safety of driver.The buffer device for collision of automobile of the present invention can be buffered twice when automobile is by severe crash, improved the collision energy of automobile, reduced the speed of collision, while also improving safety guarantee to occupant.
Description
Technical field
The present invention provides a kind of buffer device for collision of automobile, belong to car protective device technical field.
Background technology
Automobile is early due to its is convenient, fast to have become the vehicles closely bound up in people's life.Recent years with
The owning amount of the raising of living standards of the people, automobile is constantly promoted.But the traffic accident of motor vehicle is also showed and is passed year by year
The trend of increasing.With the continuous development of automobile industry, the speed of running car is also getting faster, when head-on crash occurs for automobile
When, the component being collided at first is bumper, and traditional bumper cannot meet the requirement of automotive safety in high velocity impact.
When speed very it is high collide when, huge inertia force can make automobile head that serious deformation occur.Therefore need one kind can
The buffer unit of buffer capacity when reducing acceleration when collision, enhancing car crass, this device can be protected interior
Personnel protect the appearance of automobile as far as possible simultaneously.
Invention content
For the above-mentioned prior art the problem of Shortcomings, the purpose of the present invention is to propose to a kind of buffering automobile collision dresses
It sets, acceleration when collision energy-absorbing ability, reduction car crass can be enhanced, the safety and protection vapour of occupant can be protected
The appearance of vehicle.
To achieve the above object, the present invention provides a kind of buffer device for collision of automobile.A kind of buffer device for collision of automobile,
It is made of bumper, leaf spring, buffer spring, bump rubber, connecting rod and crash energy absorption equipment.
A kind of buffer device for collision of automobile, the energy absorption device include energy-absorbing cylinder, gag lever post, damping spring, buffering elastic
Spring, fixed plate, energy-absorbing cylinder shell.There are two this energy absorption devices, is arranged symmetrically in the left and right sides of bumper, on horizontal direction
One end is connect with bumper.Fixed plate energy-absorbing cylinder shell installed above is equipped with energy-absorbing in the energy-absorbing cylinder shell
Cylinder, the energy-absorbing cylinder shell is interior to install buffer spring, and the energy-absorbing cylinder shell both sides are symmetrically installed with gag lever post, described
Gag lever post is connect with the damping spring of the upper surface of fixed plate.
A kind of buffer device for collision of automobile, the bump rubber is mounted on behind leaf spring, in yielding rubber
3-6 buffer springs are installed inside block.
A kind of buffer device for collision of automobile, the connecting rod connect bump rubber and crash energy absorption equipment.
A kind of buffer device for collision of automobile, the energy-absorbing cylinder and housing cross-sectional are circle.
A kind of buffer device for collision of automobile, the gag lever post are right-angled trapezium.
A kind of effective income for buffer device for collision of automobile that the present invention uses is：It is mounted with to inhale behind bumper
Energy device, and bump rubber is mounted with behind leaf spring, bump rubber and crash energy absorption equipment are connected with connecting rod,
Energy absorption ability of the automobile in collision is improved in this way, can be reduced acceleration of the automobile in collision, can preferably be protected
Interior personnel safety.

Blob of viscose 32- buffer spring 41- energy-absorbing cylinder 42- gag lever post 43- damping spring 44- buffer spring 45- fixed plates 46- inhales
It can cylinder shell
Specific implementation mode
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 buffer device for collision of automobile, by bumper 1, steel
Flat spring 2, bump rubber 3, crash energy absorption equipment 4, connecting rod 5 form, and there are two the crash energy absorption equipments 4, symmetrical cloth
One end on the left and right sides of bumper 1, horizontal direction is set with bumper rigid 1 to be connected.
Crash energy absorption equipment 4 described in attached drawing 3 include energy-absorbing cylinder 41, gag lever post 42, damping spring 43, buffer spring 44,
Fixed plate 45, energy-absorbing cylinder shell 46, the 45 energy-absorbing cylinder shell 46 installed above of fixed plate, in the energy-absorbing cylinder shell 46
Energy-absorbing cylinder 41 is installed, buffer spring 44 is installed in the energy-absorbing cylinder shell 46,46 both sides of energy-absorbing cylinder shell are symmetrical
Gag lever post 42 is installed, the gag lever post 42 is connect with the damping spring of the upper surface of fixed plate 45.
Bump rubber 3 described in attached drawing 2 is mounted on behind leaf spring 2, in 3 the inside installation 3-6 of bump rubber
A buffer spring 32 is equipped with connecting rod 5 in the rear end of bump rubber 3, connects bump rubber 3 and energy-absorbing cylinder 41.
Energy-absorbing cylinder 41 and 46 cross section of energy-absorbing cylinder shell described in attached drawing 3 are circle.
Gag lever post 42 described in attached drawing 3 is right-angled trapezium.
Specifically, when automobile collides, automotive front end bumper 1 generates deformation, and leaf spring 2 is to 1 energy of bumper
Enough play the role of shoring, collision is worked as a buffer, when 1 deformation of bumper is more than that leaf spring 2 is withstood forces, external force can push away
Dynamic right-angled trapezium gag lever post 42, energy-absorbing cylinder 41 moves backward, bumper 1, leaf spring 2, bump rubber 3, buffering energy-absorbing dress
It sets 4, buffer spring 44 and damping spring 43 while deforming upon, connecting rod 5 can be with bump rubber 3 and crash energy absorption equipment 4
Deformation move backward, acceleration when collision can be reduced in this way, can ensure the safety of occupant, when external force eliminate
Afterwards, bumper 1, leaf spring 2, bump rubber 3, crash energy absorption equipment 4, connecting rod 5 can be extensive in the case of reaction force
Initial state is arrived again.
