[0002] At present, when traffic management departments and construction departments need to occupy roads in an emergency, most of the road traffic signs they use are display boards with reflective films with traffic sign patterns. This type of traffic sign can also allow pedestrians to recognize the traffic sign pattern on it during the day or when the light is good. At night or in dim light, the specific content on the sign cannot be correctly identified due to the poor reflective effect of the traffic sign. After searching, it was found that the prior public utility model patent with publication number CN220340789U discloses a solar LED traffic induction screen trailer, which drives the placement block to rotate out of the placement slot through a driving mechanism, so that the induction screen can indicate the real-time road conditions of the road section in a smooth, blocked or crowded state, so that the driver can judge and choose the appropriate driving route, thereby eliminating the need for manual handling by construction personnel, so as to reduce the labor intensity of construction personnel. The slider is driven to move by a motor, and the slider then pushes the induction screen to flip through a connecting rod, and the overall structure is complex. Utility Model Content
