The roller row may be, but not limited to, a structure including two fixing plates, a fixing shaft disposed between the two fixing plates, and a roller fitted over the fixing shaft.

In one example, the upper cross beam and the lower cross beam are provided with grooves on the sides close to the buffer assembly. Compared with the arrangement at the top or the bottom of the upper cross beam and the lower cross beam, the protection strength of the whole guard rail is higher due to the arrangement at the side.

In one example, the grooves comprise a first groove and a second groove which are arranged in parallel, and two supports of the torsion spring piece are respectively arranged in the first groove and the second groove in a sliding mode, so that the stability of the buffering assembly is improved.

In one example, the end of the support connected with the upper cross beam or the lower cross beam is provided with a roller, and after being impacted, the two supports can move in the groove in a diverging mode more smoothly so as to exert the buffering effect of the buffering assembly.

In one example, the rollers of the roller row are provided with rubber sleeves, so that impact damage is reduced.

In one example, a plurality of reinforcing cross beams are further connected to the upright post between the upper cross beam and the lower cross beam, so that the protection strength of the guard rail is improved.

In one example, the bottom of the upright is provided with a fixing plate for fixing the upright.

In one example, the side of the upright column far away from the buffer assembly is also connected with an inclined strut, so that the protection strength of the protective guard can be improved.

In one example, the upper part of the upright post is bent towards one side of the buffer assembly, so that the rollover probability of the vehicle can be reduced to a certain extent.

The utility model adopts the above technical scheme, the advantage that has is:

1. according to the protective guard, through the arrangement of the buffer assembly, a buffer force can be given to an impactor after the impactor is impacted, and impact damage is reduced; through the setting of cylinder row, can play the diversion effect of cylinder on it after being strikeed to reduce striking damage and turnover probability, and under the cushioning effect that the cylinder was arranged, can better exert the diversion effect of cylinder more easily.

2. Because the striking angle majority that the impactor was arranged with the cylinder is the impact of non-right angle, this application adopts the torsional spring buffering striking to use the back, and the unusual deformation damage of torsional spring is less.

3. The first groove and the second groove are respectively matched with the two supports of the torsion spring piece, so that better buffering stability can be ensured; the support end adopts the gyro wheel, can make two supports more smoothly fork the slip in the recess to better performance buffering subassembly's cushioning effect.
