Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, specifically to an AGV transport vehicle with a collision warning structure. Background Technology

[0002] AGV stands for Automated Guided Vehicle, also known as automated guided vehicle or automated guided transport vehicle. AGVs are industrial vehicles that load goods automatically or manually, travel automatically along a set route or pull a cargo trolley to a designated location, and then load and unload goods automatically or manually.

[0003] However, current AGV intelligent transport vehicles are entirely controlled autonomously by programs. This means that if the internal driving program malfunctions, the AGV's driving safety will be greatly reduced, increasing the risk of collisions. Upon impact, the AGV's internal program will be further affected by the shock. Therefore, we propose an AGV transport vehicle with a collision warning structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an AGV transport vehicle with a collision warning structure, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an AGV transport vehicle with a collision warning structure, comprising: a mobile vehicle body; a lifting pallet is provided on the top of the mobile vehicle body, the lifting pallet being used for lifting and lowering to transport goods; several split-type anti-collision side plates are provided on the outer side of the mobile vehicle body, a laser radar is provided on the outer side of the anti-collision side plates, several ultrasonic sensors are provided at the corners on both sides of the anti-collision side plates, several airbag assemblies are provided on the outer wall of the mobile vehicle body, and the airbag assemblies are located on the inner side of the anti-collision side plates; several buffer assemblies are provided between the anti-collision side plates and the mobile vehicle body; and an electric contact switch linked to the buffer assemblies is installed on the inner side of the mobile vehicle body, the electric contact switch being used to receive the movement of the buffer assemblies to stop the vehicle.

[0006] Preferably, a warning module is provided at the corner of the lifting platform, and the warning module includes at least two elements: sound and light.

[0007] Preferably, the anti-collision side panel is arranged parallel to the moving vehicle body, and the distance between the anti-collision side panel and the moving vehicle body is three to eight centimeters.

[0008] Preferably, the lidar is a strip design and the ultrasonic sensor is a dot design.

[0009] Preferably, the airbag assembly includes a mounting slot disposed on the outside of the mobile vehicle body, and an airbag is disposed inside the mounting slot. An air supply module for inflating the airbag is disposed inside the mobile vehicle body.

[0010] Preferably, the buffer assembly includes a guide post fixed to the anti-collision side plate, the guide post being slidably inserted into the interior of the moving vehicle body, a spring being provided on the outside of the guide post, the spring being located between the anti-collision side plate and the moving vehicle body, and a limiting plate being provided on the outside of the guide post located inside the moving vehicle body.

[0011] Preferably, the electric shock switch includes a fixing frame fixed to the inner wall of the mobile vehicle body, and a restraining sleeve is provided at the bottom end of the fixing frame. A sliding rod is inserted into the inside of the restraining sleeve, a wiring terminal is provided on the outside of one end of the restraining sleeve, and a contact point is provided inside the restraining sleeve.

[0012] This utility model provides an AGV transport vehicle with a collision warning structure, which has the following beneficial effects:

[0013] 1. The ultrasonic sensors and lidar used can monitor surrounding obstacles during normal operation of the trolley, ensuring the normal transport of goods. When the trolley's operation program malfunctions, the buffer components and anti-collision side plates can be used to achieve mechanical anti-collision of the trolley. The movement of the buffer components can activate the electric contact switch to achieve the purpose of emergency stopping of the trolley.

[0014] 2. The airbag assembly used can move the buffer assembly after the anti-collision side plate contacts the obstacle in the event of a collision. At this time, the electric switch is triggered, which starts the air supply module to quickly inject gas into the airbag, preventing the anti-collision side plate from contacting the vehicle body and providing good protection for the vehicle body.

[0025] In this embodiment, several separate anti-collision side panels 3 are provided on the outer side of the mobile vehicle body 1. The anti-collision side panels 3 are made of elastic materials (such as silicone or polyurethane) to absorb low-speed collision energy. A lidar 4 is provided on the outer side of the anti-collision side panels 3. The lidar 4 scans the surrounding environment by emitting laser beams to generate a high-precision map and detect the position and distance of obstacles in real time. Several ultrasonic sensors 5 are provided at the corners on both sides of the anti-collision side panels 3. The ultrasonic sensors 5 are used for short-range obstacle detection (such as ground protrusions or people approaching), compensating for the blind spots of the lidar. The anti-collision side panels 3 are arranged parallel to the mobile vehicle body 1, and the distance between the anti-collision side panels 3 and the mobile vehicle body 1 is three to eight centimeters. The lidar 4 has a strip design, and the ultrasonic sensors 5 have a point design. The lidar 4 can scan obstacles in the direction of movement, and the ultrasonic sensors 5 can monitor corners or blind spots, ensuring the safe operation of the vehicle.

[0027] In this embodiment, a plurality of buffer components 7 are provided between the anti-collision side plate 3 and the moving vehicle body 1. The buffer components 7 include guide posts 71 fixed on the anti-collision side plate 3. The guide posts 71 are slidably inserted into the interior of the moving vehicle body 1.

The electric contact switch 8 is used to activate the air supply module 63 of the airbag assembly 6, which generates gas to open the airbag 62 to buffer the anti-collision side plate 3. At the same time, the electric contact switch 8 triggers the vehicle to perform emergency braking.
