[0002] An automated guided vehicle (AGV) is an industrial vehicle that loads goods automatically or manually, automatically drives along a set route or pulls a cargo trolley to a designated location, and then loads and unloads goods automatically or manually. An AGV is an automatically controlled industrial vehicle powered by a battery. An automated guided vehicle can only truly function if it is combined with an automated guiding system, an automatic loading and unloading system, a communication system, a safety system, and a management system to form an automated guided vehicle system (AGVS) in accordance with the requirements of automation, flexibility, and punctuality in material handling operations.

[0003] When an automatic guided vehicle is transporting goods, it is easy to collide when encountering an obstacle. When a collision occurs, on the one hand, it is easy to cause damage to the vehicle body. On the other hand, when a collision occurs, the goods on the vehicle are easy to tip over, which is more dangerous.

[0004] To this end, we propose an anti-collision automatic guided vehicle to solve the above problems. Utility Model Content

Springs are provided in the two cavities, and the two ends of the springs are fixedly connected to the inner side walls of the cavities and the slides respectively.

[0009] Preferably, the buffer mechanism includes a buffer groove arranged on the side wall of the guide vehicle body, a limiting rod is fixedly connected in the buffer groove, a buffer block is provided on the sliding sleeve outside the limiting rod, the buffer block is slidably connected to the inner side wall of the buffer groove, a buffer spring is provided on the outer sleeve of the limiting rod, the two ends of the buffer spring are respectively fixedly connected to the buffer block and the inner side wall of the buffer groove, the side wall of the buffer block is rotatably connected to a deflection plate, and the end of the deflection plate away from the buffer block is rotatably connected to the rotating plate.

[0010] Preferably, a rubber pad is fixedly connected to the first anti-collision plate and the second anti-collision plate on one side away from the guide vehicle body.

When the distance is too close, the distance sensor senses and feeds back an electrical signal to the automatic guided vehicle, so that the automatic guided vehicle stops and searches for other moving paths to avoid the automatic guided vehicle from colliding. When the first anti-collision plate moves down, the buffer pad contacts the ground and has a braking effect. When the second anti-collision plate moves up, the second anti-collision plate extends above the guide vehicle body to protect the goods above the vehicle body and prevent the goods from tipping over.

[0015] The utility model will not cause damage to the guide vehicle body when encountering a collision, and can protect the goods during the collision to avoid the situation that the goods dump, thereby improving the safety of the goods transportation. BRIEF DESCRIPTION OF THE DRAWINGS
