Abstract
Automobile impact force absorber belongs to field of transport machinery.This project is by the back steel plate and the front spring that are fixed in automobile big rack front portion, and is installed at least four spring fore-set socket type slip joint formations of being with lever bayonet lock and trip between back steel plate and the front spring.When automobile meets accident bump under steam, the impact compression spring, slip joint is compressed, and the lever bayonet lock snaps in the corresponding trip, does not make springback, thereby automobile impact force is all assimilated, and guarantees the people life property safety.When desire resets front spring afterwards, knock the lever bayonet lock and do not have bayonet lock one end afterbody bonded assembly restoring link, then restoring link drives the trip of lever bayonet lock from inner core and withdraws from, and outer spring and inner spring unmuzzle, and the front spring of upspringing is replied the normal position.This project is to the crucial meaning that assured the safety for life and property of the people.
Description
Technical field:
Automobile impact force absorber, just a kind of later-model Federal bumper belongs to field of transport machinery.
Technical background:
The develop rapidly of modern automobile technology and communications and transportation has also brought people life property safety's problem as side production.Automobile meets accident out of control under steam, will cause car crash.Numerous traffic accident tragedies have proposed the challenge that assures the safety for life and property of the people to us.Someone has designed auto against energy absorber (publication number CN2299770), principle is that the bumper/spoiler that is impacted promotes to shear projection backward, shears the projection shearing and is sheared plate, and being sheared plate is gapped a lot of layer, be sheared plate and cut successively, thus the impact of consuming.The shortcoming of this scheme is to be sheared plate and to be subjected to basic destruction, the necessary afterwards new product of changing.Also the someone has designed automobile protective frame (publication number CN2815781), and principle is two fore-sets about the bumper/spoiler that is impacted promotes backward, and two crooked two groups of spring steel plates of fore-set reach protective effect.The shortcoming of this scheme is that spring steel plate can rebound, and may cause the secondary injury to the people.
Summary of the invention:
At two steel plates that have the skirt section of the anterior installation of automobile chassis frame, back steel plate is fixed in the vehicle frame front end, and the spring fore-set socket type slip joints of four band bayonet lock trips are installed between the steel plate of front and back at least.Automobile meets accident when bump under steam, and front spring retreats, compression spring, and slip joint is compressed, and the lever bayonet lock snaps in delegation's trip on the inner core successively, does not make springback, thereby automobile impact force is all assimilated.For convenience front spring is resetted afterwards, designed the restoring link of two interlocks, knock restoring link, then connecting rod drives the trip of lever bayonet lock from inner core and withdraws from, and outer spring and inner spring unmuzzle, and the front spring of upspringing is replied the normal position.Crucial meaning has assured the safety for life and property of the people when clashing into beyond the present invention takes place automobile.
Description of drawings:
Accompanying drawing is the automobile impact force absorber birds-eye view.
The specific embodiment:
As shown in the figure, the slip joint urceolus 10 of automobile impact force absorber is fixed on the steel plate 12 of back, and slip joint inner core 4 is fixed on the front spring 2.Inner spring 11 is installed in the urceolus 10, the inner core 4 outer outer springs 5 of installing, there is dust protection rubber cover 1 outside of outer spring 5.Outer spring 5 withstands on the top of urceolus 10, and inner core 4 withstands inner spring 11.A hole is arranged on the slip joint urceolus 10, and lever bayonet lock 8 enters urceolus 10 from this hole; Between lever bayonet lock 8 and the urceolus 10 spring 6 is arranged, no bayonet lock one end of support lever bayonet lock 8 is outside, and then bayonet lock one end that has of lever bayonet lock 8 has an inside power all the time, is stuck in the corresponding trip 9 on the inner core 4.
The skirt section 15 of the skirt section 3 of front spring and back steel plate all is two up and down, the intensity of steel plate before and after can strengthening; The engine bed 13 that driving engine is installed is arranged on the skirt section 15 of back steel plate.No bayonet lock one end of lever bayonet lock 8 turns an angle of 90 degrees downwards, and about all slip joints are divided into two groups, no bayonet lock one end of each group lever bayonet lock flexibly connects with restoring link 7.
When automobile met accident bump under steam, impact contracted after making front spring, compression outer spring and inner spring, and slip joint is compressed, and lever bayonet lock 8 snaps in the corresponding trip 9, does not make springback, thereby automobile impact force is all absorbed.
When desire resets front spring 2 afterwards, knock restoring link 7, then restoring link 7 drives the trip 9 of lever bayonet lock 8 from inner core 4 and withdraws from, and outer spring 5 and inner spring 11 unmuzzle, and the front spring 2 of upspringing is replied the normal position.
According to the actual needs of dissimilar vehicles, the front and back steel plate can be a linear, also can be curvilinear figure; The quantity of slip joint has four at least, and full size vehicle can have 6-10, even more.
Claims (8)
1. an automobile impact force absorber is characterized in that, by the back steel plate and the front spring that are fixed in automobile big rack front portion, and is installed at least four band lever bayonet locks between back steel plate and the front spring and the spring fore-set socket type slip joint of trip constitutes.
2. automobile impact force absorber according to claim 1 is characterized in that, two restoring links that are movably connected in lever bayonet lock tail end are arranged.
3. the lever bayonet lock of slip joint according to claim 1 is characterized in that, no bayonet lock one end turns an angle of 90 degrees downwards.
4. socket type slip joint according to claim 1 is characterized in that, outer spring, inner spring and the spring between lever bayonet lock and urceolus are arranged.
5. socket type slip joint according to claim 1 is characterized in that, urceolus has an opening that supplies the lever bayonet lock to enter.
6. socket type slip joint according to claim 1 is characterized in that outer spring has dust protecting cap.
7. socket type slip joint according to claim 1 is characterized in that, inner core has the equidistant serration trip that has inclined-plane backward of delegation.
8. lever bayonet lock according to claim 1 is characterized in that, there is an inclined-plane forward the end.
