Abstract
The utility model relates to a kind of car crusherbull zone mechanisms, it is made of bumper, leaf spring, buffer spring, bump rubber and buffer unit, there are two the buffer units, it is arranged symmetrically in the left and right sides of bumper, one end is just contacted with bumper in transverse 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.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.Buffer unit 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 car crusherbull zone mechanism of the utility model can be buffered repeatedly when automobile is by severe crash, improve the collision energy of automobile, reduce the speed of collision, while also improving safety guarantee to occupant.
Description
Technical field
The utility model provides a kind of car crusherbull zone mechanism, belongs 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, China has been
Automobile possesses big country, and the annual automobile there are also ten million enters huge numbers of families.But the traffic accident of motor vehicle also show by
The trend that year is incremented by.With the continuous development of automobile industry, the speed of running car is also getting faster, and is touched when front occurs for automobile
When hitting, the component being collided at first is bumper, and traditional bumper is not able to satisfy wanting for automotive safety in high velocity impact
It asks.When speed very it is high collide when, huge inertia force can make automobile head that serious deformation occur, and be easy to produce biggish
Impact force damages driver and passenger.When therefore needing a kind of acceleration when can reduce collision, enhancing car crass
The buffer gear of buffer capacity, this mechanism can protect interior personnel and meanwhile protect as far as possible the appearance of automobile not by
It destroys.
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 crusherbull zone
Mechanism can enhance acceleration when collision energy-absorbing ability, reduction car crass, can protect the safety and protection of occupant
The appearance of automobile.
To achieve the above object, the utility model provides a kind of car crusherbull zone mechanism.A kind of buffering automobile collision
Mechanism is made of bumper, leaf spring, buffer spring, bump rubber and buffer unit.The buffer unit includes slow
Cylinder is rushed, the dsah-pot is fixed on the crossbeam of car, and piston mandril, the top of piston mandril are stretched out in the dsah-pot front end
End is fixed on car insurance bar, and the buffer unit is by former and later two buffer sets at by fixing between the buffer area of front and back
Sealing column separates, and the through-hole of connection front and back buffer area is provided on fixing seal column, and the preceding buffer area includes piston, pressure
Contracting spring and hydraulic oil, the rear buffer area includes piston and compressed spring.
A kind of car crusherbull zone mechanism, there are two the energy absorption devices, is arranged symmetrically in the left and right sides of bumper,
One end is just contacted with bumper in transverse direction.
A kind of car crusherbull zone mechanism, the bump rubber is mounted on behind leaf spring, in yielding rubber
3-6 buffer springs are installed inside block.
A kind of effective income for car crusherbull zone mechanism that the utility model uses is: installing behind bumper
Buffer unit, and bump rubber is mounted with behind leaf spring, in this way improve buffer capacity of the automobile in collision
Power can reduce acceleration of the automobile in collision, can preferably protect interior personnel safety.
Detailed description of the invention
Attached drawing 1 is a kind of overall construction drawing of car crusherbull zone mechanism.
Attached drawing 2 is a kind of structure chart of the bump rubber of car crusherbull zone mechanism.
Attached drawing 3 is a kind of structure chart of the buffer unit of car crusherbull zone mechanism.
In attached drawing: 1- bumper 2- leaf spring 3- bump rubber 4- buffer unit 31- bump rubber 32-
Compressed spring 44- hydraulic oil 45- through-hole 46- fixing seal column before buffer spring 41- piston mandril 42- secondary piston 43-
Compressed spring 49- dsah-pot after piston 48- after 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 crusherbull zone mechanism, by bumper 1, steel
Flat spring 2, bump rubber 3, buffer unit 4, there are two the crash energy absorption equipments 4, is arranged symmetrically in a left side for bumper 1
Right two sides, one end is connected with bumper rigid 1 in transverse direction.
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.
Buffer unit 4 described in attached drawing 3 includes piston mandril 41, secondary piston 42, preceding compressed spring 43, hydraulic oil 44, leads to
Hole 45, fixing seal column 46, rear piston 47, rear compressed spring 48, dsah-pot 49, the dsah-pot 49 are fixed on the crossbeam of automobile
On, dsah-pot 49 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, preceding compressed spring 43 and hydraulic oil in preceding buffer area
44, rear piston 47 and rear compressed spring 48 are provided in rear buffer area.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.
49 cross section of dsah-pot described in attached drawing 3 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 1 deformation of bumper is more than that leaf spring 2 is withstood forces, external force can be pushed
The preceding compressed spring 43 in preceding buffer area is passed to by piston mandril 41 and secondary piston 42, second is generated and buffers, preceding buffering
Hydraulic oil 44 in area is entered in rear buffer area by through-hole 45, and compressed spring 48 after being squeezed by rear piston 47 generates third time
Buffering, by buffering three times, alleviates impact force significantly, reduces the impact force of automobile, the safety of effective protection people and automobile.
After collision, rear compressed spring 48 is sprung back, so that preceding compressed spring 43 is sprung back, restores reset condition.This buffering automobile collision machine
The impact force of automobile can be greatly lowered, can play buffer function by structure, to driving people when greatly reducing car crass
Injury caused by member.
