Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolleys, in particular to an anti-collision component for a storage AGV trolley. Background Art

[0002] In order to ensure safety and efficiency during the operation of warehouse AGV (automatic guided vehicle), anti-collision components are usually required. These components can help AGV stop automatically when encountering obstacles, avoid collisions, and ensure the smooth progress of warehousing operations. Common anti-collision components include: Sensors: such as infrared sensors, ultrasonic sensors, laser sensors, etc. These sensors can detect obstacles in front of the AGV. When obstacles are detected, they will send signals to the control system algorithm. Control system: After receiving the sensor signal, the control system will determine whether the AGV needs to stop or change direction according to the preset program and algorithm. Actuators: such as motors, brake systems, etc. When the control system issues an instruction, these actuators will make the AGV stop or change its path in time. Anti-collision bars / columns: In the warehouse, some special anti-collision bars or anti-collision columns may be set up to physically Limit the AGV's route and reduce the possibility of collision to a certain extent. Software algorithms: including path planning, obstacle detection, obstacle avoidance strategy, etc. These algorithms are the core of the effective operation of the anti-collision system. When designing and selecting anti-collision components, it is necessary to consider the specific application scenarios, running speed, load and other factors of the AGV to ensure the reliability of the anti-collision system. At the same time, the convenience and cost-effectiveness of maintenance should also be considered. In order to meet the ever-changing market demand and technological progress, the anti-collision technology of warehouse AGV carts is also constantly updated and developed, including more advanced sensor technology, more efficient control algorithms and more intelligent decision-making systems. In the existing technology, the anti-collision structure is not easy to disassemble. When maintenance or replacement is required, it will take more time and labor, which will lead to longer downtime of the AGV cart, affect the efficiency of warehousing operations, and increase maintenance costs.
