The invention provides a vehicle-mounted warning sign based on a servo motor. The vehicle-mounted warning sign comprises a shell, clamping blocks which are symmetrical front and back are fixedly arranged on the end face of the top of the shell, unfolding mechanisms for unfolding the warning sign are arranged on the clamping blocks, roller shafts which are symmetrical left and right and extend towards the front side and the rear side are arranged in the shell left and right, and rollers which are symmetrical front and back are fixedly arranged on the roller shafts. The warning sign can be automatically unfolded in the coming vehicle direction, secondary accidents caused by walking of personnel are avoided, meanwhile, the warning sign is declared and stabilized on the ground through a stabilizing device after being unfolded, the output power of the stabilizing device is increased according to the field wind power, and therefore it is guaranteed that the warning sign is stably placed to remind coming vehicles behind of avoiding secondary accidents; and after the operation is completed, the equipment can be controlled to be automatically retracted, so that personnel are prevented fromstaying on the traffic artery for a long time, the probability of secondary accidents is greatly reduced, and the traffic safety is guaranteed.
本发明公开了一种基于伺服电机的车载警示标牌,包括壳体,所述壳体顶部端面上固定设有前后对称的装夹块,所述装夹块上设有展开警示标牌的展开机构,所述壳体内左右设有左右对称的且朝前后两侧延伸的滚轮轴,所述滚轮轴上固定设有前后对称的滚轮;本发明实现了警示标牌向来车方向自动展开,避免人员走动造成二次事故,同时在展开后通过稳定装置是申报稳定在地面上,并更具实地的风力大小增大稳定装置的输出功率,从而保证警示牌稳固的摆放,提醒后方来车避免发生二次事故,在完成作业后可以控制设备自动收回,避免人员在交通大动脉上长时间逗留,极大的减少了二次事故发生的概率,保障了交通安全。
