Unit 2, the one end of the second buffer cell 2 is telescopically in the first buffer cell 1, and the other end of the second buffer cell 2 is compressed
On bumper 6；That is, the side of the second buffer cell 2 is in contact with bumper 6, can be with the deformation of bumper 6
Performed relative motion in the first buffer cell 1.
Spring 3, spring 3 is located between the first buffer cell 1 and the second buffer cell 2.That is, spring 3 realizes
Buffering between one buffer cell 1 and the second buffer cell 2, when bumper 6 deforms, makes the second buffer cell 2 in phase
When making contractile motion to the first buffer cell 1, spring 3 can give the second buffer cell 2 and make to deviate from the effect of the first buffer cell 1
Power.
Cushion pad 5, cushion pad 5 is set on the second buffer cell 2, and its one end is pressed on block 24, and the other end is supported
It is pressed in the first module 1.Specifically, cushion pad has the effect for slowing down impulsive force, and the second buffer cell 2 is constantly transported to the right
It is dynamic, when inconsistent with the left surface of the first buffer cell 1, it can now extrude cushion pad 5, corresponding cushion pad 5 can be to can be to the
Two buffer cells 2 produce the power to left movement, play a part of further buffering impulsive force.
When vehicle hits, when vehicle hits, bumper 6 deforms in the presence of impulsive force, makes second
Single 2 yuan of buffering is moved right, and then the spring 3 being located between the second buffer cell 2 and the first buffer cell 1 is also received to the right
Contracting motion, the contractile motion of spring 3 plays cushioning effect to impulsive force, and in the process, with the second buffer cell 2 with
The increase of relative displacement between first buffer cell 1, the cushion pad 5 for being set in the outside of the second buffer cell 2 can be with the first buffering
Unit 1 is inconsistent, and further cushioning effect can be played to impulsive force.Contractile motion is made by spring 3 and cushion pad 5, can be had
Effect ground absorbs the impulsive force produced during vehicle collision, and the apparatus structure is simple, safe and reliable.
In one embodiment of the invention, as shown in FIG. 1 to 3, the first buffer cell 1 include relative left end edge and
First chamber 13 is provided with relative right-hand member edge, the first buffer cell 1, the first chamber 13 is through the first buffer cell 1
Left end edge and not through its right-hand member edge, base 11 is provided with right-hand member edge.That is, the inside of the first buffer cell 1 is provided with a left side
The first chamber 13 of opening is provided with ora terminalis, the second buffer cell 2 can be made in first chamber 13 at stretching motion, right-hand member edge
Base 11 is fixed on vehicle frame, for example, can set external screw thread on the pedestal 11, and internal thread hole, the first buffering are set on vehicle frame
Unit 1 is cooperated by external screw thread and internal thread hole and itself is fixed on vehicle frame.Certain present invention is not restricted to this,
Base 11 can also be fixed on vehicle frame by way of welding.

Selection of land, buffer stopper 4 includes the first buffer stopper 41 and the second buffer stopper 42, and the first buffer stopper 41 is fixedly linked with base 11, and second
Buffer stopper 42 is located between the buffer stopper 41 of spring 3 and first, and is connected respectively with the buffer stopper 41 of spring 3 and first, wherein, first
Buffer stopper 41 is rubber parts, and the second buffer stopper 42 is nylon part.Rubber parts has prominent high resiliency, can effectively absorb punching
Power is hit, the not only flexible but also very high fatigue resistance of nylon part can be reasonably resistant to spring 3 to its impact and rub
Wipe.The impulsive force of 3 pair of first buffer cell 1 of spring is absorbed by setting buffer stopper 4 further can be played to spring 3.
In one embodiment of the invention, as shown in FIG. 1 to 3, in addition to block 12, block 12 is formed integrally on
At left end edge, and extend to the second buffer cell 2.Specifically, block 12 adapts to the second buffer cell 2, can be slow to second
Rush unit 2 and play a part of guiding on the side-to-side movement direction in the first buffer cell 1.
Further, as shown in FIG. 1 to 3, the outside of the second buffer cell 2 is provided with projection 23, projection 23 and the phase of block 12
It is right.Specifically, projection 23 is formed integrally on the outside of the second buffer cell 2, corresponding with block 12 to set, and is buffered to second
Restriction is played a part of in the motion of unit 2.I.e. the second buffer cell 2 is limited in the first buffer cell 1, it is to avoid the second buffering is single
Member 2 is hauled out in the first chamber 13 of the first buffer cell 1.
In one embodiment of the invention, as shown in FIG. 1 to 3, the second buffer cell 2 include relative left end edge and
Relative right-hand member edge, the second buffer cell 2 is provided with second chamber 22, and second chamber 22 runs through the right-hand member edge of the second buffer cell 2,
One is provided with drift at its left end edge.That is, spring 3 is moved in second chamber 22, by setting second chamber 22
Restriction can be played a part of to the motion of spring 3, spring 3 is made contractile motion in the lateral direction as far as possible, with
Preferably absorb impulsive force.Spring 3 can be effectively protected by setting drift 21 to be pressed on bumper 6, and can be made
The power that spring 3 gives bumper 6 is more preferably uniform.Preferably, drift 21 for disc-shaped structure.Disc structure processing is simple,
Save space and the raw material of automobile buffer.
