Description

A kind of motor vehicle multi-buffer energy absorption device
Technical field
The utility model is related to a kind of motor vehicle multi-buffer energy absorption devices.
Background technology
By bumper, energy-absorption box etc., some associated components form the damping energy absorber that Hyundai Motor generally uses.Tradition Automobile impacting protection mechanism is realized that effect is single, and effect is limited, is insufficient for hitting by the energy-absorption box of bumper rear end When hitting, the security protection that is brought to passengers inside the car.
Utility model content
Its purpose of the utility model, which is that, provides a kind of motor vehicle multi-buffer energy absorption device, solves orthodox car and hits Protection mechanism is hit by the energy-absorption box of bumper rear end to realize, effect is single, and effect is limited, when being insufficient for hitting The problem of waiting, security protection brought to passengers inside the car.
It adopts the technical scheme that achieve the above object, a kind of motor vehicle multi-buffer energy absorption device, including through holding Weight frame is fixed on the anticollision steel plate on longitudinal beam, and the anticollision steel plate one side is equipped with multiple anti-billiards, and anticollision steel plate is another One end with multiple dampers is connected on one side, and the other end of damper is connected with crumple cylinder, crumple cylinder via pins and longitudinal beam It is fixedly connected, damping spring is additionally provided on the damper.
Advantageous effect
The utility model has the following advantages compared with prior art.
The utility model can tackle the shock of a variety of situations, and effective guarantee is provided for the safety of passengers inside the car, and can To reduce the deflection of automobile engine and compartment, maintenance cost is reduced for car owner, there is multistage protection, of low cost, installation It is simple and effective, anticollision effect clear advantage.
Description of the drawings
Below in conjunction with attached drawing, the utility model is described in further detail.
Fig. 1 is the structure diagram of the utility model;
Fig. 2 is the anti-billiards constant cross-section schematic diagram of the utility model.
Specific embodiment
The present apparatus includes the anticollision steel plate 2 being fixed on through bearing frame 3 on longitudinal beam 8, as shown in Figure 1 and Figure 2, described anti- 2 one side of steel plate is hit equipped with multiple anti-billiards 1,2 another side of anticollision steel plate is connected with one end of multiple dampers 4, damper 4 The other end be connected with crumple cylinder 6,6 via pins 7 of crumple cylinder are fixedly connected with longitudinal beam 8, are additionally provided with and subtract on the damper 4 Shake spring 5.
The anti-billiards 1 is made of rubber material, and the anticollision steel plate 2 is equipped with groove, and groove connects anti-1 bottom of billiards Convex block, anti-billiards 1 is fixed on by the form of buckle on anticollision steel plate 2.
The utility model is combined using anti-billiards 1 with anticollision steel plate 2, and is connected with damper 4, passes through connecting vehicle frame 6 device of crumple cylinder before longeron 8 forms a multi-buffer energy absorption device to substitute traditional collision prevention girders.Anti- billiards 1 passes through card The form of button is fixed on anticollision steel plate 2, and damper 4 is attached with 2 rear side of anticollision steel plate, when collision generation, first anticollision Ball 1 absorbs impact force, and a part of impact force is absorbed by anti-billiards 1, and remaining impact force continues to transfer to damper 4, Impact force is absorbed using 4 good cushion performance of damper, it is still very big that damper 4 is compressed to most short and impact force When, impact force can rearward crumple cylinder 6 transfers via damper 4, and when impact force is more than the maximum shear stress of pin 7, pin 7 is sent out Raw fracture, absorbs impact force, until anticollision steel plate 2 deforms and impact force is absorbed.Wherein bearing frame 3 is to entirely filling The effects that playing support auxiliary equipment weight and maintaining structure is put, impact force is absorbed with this multi-stage mechanism, reduces and hits The injury brought to driver.
The device can carry out multi-buffer, be respectively:
Level-one damping:When slight impact occurs for vehicle, impact force is transferred via preceding plastic shell, and impact force is accommodated in anticollision On anti-billiards 1 before steel plate 2, collision energy is absorbed by anti-1 deformation of billiards.
Two level damping:When medium speed per hour collision occurs for vehicle, vehicle, which is hit, generates larger impact force, and anti-1 deflection of billiards reaches The limit still has impact force to transfer backward at this time, and automobile impact force is sent to hydraulic damper 4, and absorber spring 5 passes through hydraulic pressure Damper 4 and absorber spring 5 absorb Impact energy jointly.
Three-level damping:When higher speed collision occurs for vehicle, anti-billiards 1, damper 4 and damping spring 5 reach deformation limit, Still there is energy continuation to transfer backward at this time.When dynamics is more than the shearing force of pin 7, pin 7 is inserted into vehicle by shear fracture, crumple cylinder 6 In frame longeron 8, achieve the effect that absorb collision energy at this time by shear pin 7.
Level Four damping:When high velocity impact occurs for vehicle, anti-billiards 1, damper 4, damping spring 5 and pin 7 reach deformation The limit.The absorption realized to Impact energy itself is deformed upon by anticollision steel plate 2 at this time.
Wherein, a whole set of multi-buffer energy absorption device is longitudinal movement, and passes through bearing frame 3 and support automobile first half weight Amount.
