After using the above structure, compared with prior art, the present invention have the advantage that anticollision barrier of the invention,
Due to being provided with buffer unit, in Vehicular impact guardrail board, guardrail board can be absorbed centainly by the elastic deformation of itself
Collision energy, and in guardrail board by the shock of vehicle and to when being deformed close to the direction of fence post, guardrail board meeting
Drive push rod mobile, push rod drives the first magnet to slide to the direction close to the second magnet when mobile, when the first magnet is to second
Magnet close to when, both the first magnet and the second magnet repel each other, in this way, the first magnet needs to overcome magnetic field repulsive force when moving,
The kinetic energy of the first magnet is consumed when overcoming magnetic field repulsive force, can also absorb the collision energy of vehicle, and buffer unit
In be additionally provided with baffle, when mobile to the direction close to the second magnet when the first magnet, when the first magnet and the second magnet distance
After being closer to, the first magnet can push the second magnet mobile by magnetic field repulsive force, the second magnet move a certain distance after with
The collision of first block baffle, the movement of the second magnet of baffle, and the first magnet continues, first magnet pair close to the second magnet
The thrust of second magnet is gradually increased, and after thrust of first magnet to the second magnet increases to a certain extent, the second magnet will
First block baffle is broken through, and then push rod continues to press on the movement of the first magnet, and the first magnet continues to press on the forward movement of the second magnet,
So that the second magnet and the second block baffle are collided, after thrust of first magnet to the second magnet continues to increase to a certain extent,
Second magnet breaks through the second block baffle, in this way, and so on, muti-piece baffle successively stops the movement of the second magnet, Mei Dang
When two magnet break through a block baffle, it is absorbed by the kinetic energy of a part, a part of collision energy of vehicle is also just absorbed, passes through
Muti-piece baffle is to have the function that repeatedly to absorb vehicle collision energy, so that the buffering effect to vehicle is preferable.
And push rod has certain supporting role to guardrail board, so that guardrail board is when receiving Vehicular impact, guardrail board
It is unlikely to deform damage.
And since the thickness closer to the closed end of slideway then baffle is bigger, the thickness of baffle the big, breaks through baffle institute
The thrust needed is bigger, that is, thickness it is bigger the absorbent kinetic energy of baffle institute it is bigger, in this way, in Vehicular impact guardrail board,
The deflection of the more big then guardrail board of the impact force of vehicle is bigger, and the more big then push rod of the deflection of guardrail board drives the shifting of the first magnet
Dynamic distance is bigger, and the distance that more big then the first magnet of the moving distance of the first magnet pushes the second magnet mobile is also bigger, and second
More big then the second magnet of distance more can generate collision with the biggish baffle of thickness that magnet moves, can also absorb more vehicles
Collision energy, in this way, the absorbent vehicle collision energy of buffer unit institute is more, so that right when the impact force of vehicle is bigger
The buffering effect of vehicle is more preferable.
And in the first magnet and mobile the second magnet, elastic bumps can generate resistance to the first magnet and the second magnet
Power, the first magnet and the second magnet are by elastic bumps compressing deformation, the frictional force between the first magnet and elastic bumps, the second magnetic
Kinetic energy can be absorbed in frictional force between iron and elastic bumps, can also absorb the collision energy of vehicle, so that of the invention
The collision energy that vehicle can also be absorbed by elastic bumps, further enhances the cushion performance to vehicle.

The end of drive rod 6 is guardrail board 2 to be pressed on radial convex loop 601, in this way, in Vehicular impact guardrail board 2, guardrail board 2
It exerts a force to radial convex loop 601, so that guardrail board 2 drives drive rod 6 to move backward, and elastic component 7 is compressed by radial convex loop 601
Deformation.
A piston 26, piston 26 and hollow pipe are fixedly installed on the one end of the drive rod 6 being located in hollow pipe 9
9 inner wall is in sealing contact, closed at one end, piston 26 and the separate fence post 1 of hollow pipe 9 of the separate fence post 1 of hollow pipe 9
It is seal cavity 27 between one end, is provided with a gas outlet 28 on the roof of seal cavity 27, the top of gas outlet 28 is provided with
One for covering the cover board 29 of gas outlet 28, and cover board 29 is connected by a connecting rod 30 with connecting rod 14, in this way, working as Vehicular impact
When guardrail board 2, drive rod 6 is mobile with piston 26, and piston 26 compresses seal cavity 27 when mobile, and seal cavity 27 is compressed
When seal cavity 27 in air pressure increase, high pressure gas can buffer the impact force of vehicle, and when connecting rod 14 is mobile
It is mobile to will drive cover board 29, cover board 29 can gradually open gas outlet 28 when mobile, in this way, piston 26 is more past to move left then cover board
29 more past move right, that is to say, that the air pressure the high in seal cavity 27, and gas outlet 28 is opened bigger, can be to avoid sealing
27 air pressure of cavity is excessive and explodes.
The relatively thin thin region 32 of wall thickness is provided on one end of the separate fence post 1 of the hollow pipe 9, in this way, close
When air pressure is excessive in envelope cavity 27, thin region 32 can rupture first, and thin region 32 can carry out pressure release after rupturing, and avoid sky
Heart pipe 9 entirely explodes.
7 inner hollow of elastic component is provided with a third spring 31 in elastic component 7, and third spring 31, which is nested with, to be passed
In lever 6, the both ends of third spring 31 offset with the two sides inner wall of elastic component 7 respectively, in this way, in Vehicular impact guardrail board 2,
Elastic component 7 deforms, and elastic component 7 can compress third spring 31 when deforming, and third spring 31 buffers vehicle.
The foregoing is only a description of the preferred application of the present invention, but is not to be construed as the limit to claim
System, structure of the invention can have other variations, be not limited to above structure.In short, all in independent claims of the invention
Protection scope in made various change be within the scope of the invention.
