[0026] Among them, the bottom end of the gas spring rod 3 is provided with a valve core for air injection, and the valve core contains a one-way valve; the bottom end of the gas spring rod 3 is also sealed with a pressure sensor, which can provide a warning signal when the pressure of the gas spring rod 3 increases instantaneously.

[0027] Among them, the outer ends of the guardrail beams 4 are all fixedly provided with connecting sliders 401, which slide in a matching manner on the outside of the connecting slide block 6.

[0028] The connecting slide 6 has limit plates at both the front and rear ends. The front ends of the rear limit plate are equipped with springs and plug-in sliding pins 7. The front ends of the plug-in sliding pins 7 can fit into the rear end of the connecting slider 401.

[0029] Each guardrail beam 4 is equipped with a rotatable linkage shaft 402. The linkage shaft 402 is connected to the end of the guardrail plate 5 by a bevel gear transmission. A motor is installed in the guardrail beam 2 to drive the linkage shaft 402.

[0030] like Figures 1-4 As shown, when the car comes into contact with the guardrail beam 2, guardrail crossbeam 4 and guardrail panel 5 for various reasons, a force is generated, which pushes the guardrail beam 2 outward, and then applies pressure to the gas spring rod 3. The gas spring rod 3 provides support force at this time, buffers the car, and automatically resets after the impact.

[0031] The connecting slide 6 is installed outside the connecting slide block 401 through the plug-in slide pin 7, and the two groups of connecting slide blocks 401 can be aligned by using the connecting slide 6, so that the connecting assembly is realized, and the connecting slide block 401 has a fault tolerance effect, and if the two groups of connecting slide blocks 401 are not completely aligned, the connection can also be realized.

[0032] The connecting slide block 401 also moves in the process of moving the guardrail middle beam 2, so that the guardrail middle beam 2 realizes buffering.
