Description

Technical Field

[0001] The present invention belongs to the technical field of logistics transportation, and particularly relates to an autonomous navigation intelligent logistics transport vehicle. Background Art

[0002] With the rapid development of the logistics industry, as an indispensable part of the logistics system, the improvement of the intelligent and automated level of logistics transport vehicles is of great significance for improving logistics efficiency and reducing labor costs. In recent years, autonomous navigation technology, with its characteristics of high efficiency and accuracy, has been widely used in the field of logistics transportation. An autonomous navigation intelligent logistics transport vehicle, by integrating advanced sensor systems, control systems, and actuators, can achieve functions such as autonomous navigation, automatic obstacle avoidance, path planning, and automatic driving, significantly improving the automation and intelligent level of logistics transportation.

[0003] However, although the autonomous navigation intelligent logistics transport vehicle has made certain technological progress, there are still some defects in the aspects of environmental perception ability, flexibility, and energy efficiency in the existing technology. In terms of energy efficiency of some existing autonomous navigation logistics transport vehicles, some still use a fuel engine as the power source, which not only increases carbon emissions and environmental pollution, but also increases the operating noise, having an adverse impact on the working environment quality of logistics sites such as warehouses or factories. Moreover, the existing autonomous navigation intelligent logistics transport vehicles mainly rely on a single radar system or camera for environmental perception. This perception method is easily affected by factors such as environmental noise, lighting conditions, and obstacle occlusion, resulting in insufficient perception accuracy and stability. Especially in complex and changeable logistics transportation scenarios, such as when there are multiple narrow channels and shelves of different heights inside a warehouse, a single environmental perception method often fails to meet the high-precision perception requirements of the transport vehicle for the surrounding environment, thus restricting its driving efficiency and safety. Therefore, it needs to be improved by the staff. Summary of the Invention

[0004] The purpose of the present invention is to provide an autonomous navigation intelligent logistics transport vehicle to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0019] Preferably, the hydraulic suspension system has the ability of omnidirectional steering and can realize various driving modes such as straight driving, transverse driving, diagonal driving, swing turning, swing tail, eight-shaped turning and central rotation, adapting to complex and changeable logistics transportation scenarios.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) By designing a pure electric power mode for the autonomous navigation intelligent logistics transport vehicle, the pure electric mode is suitable for short-distance and high-frequency logistics transportation scenarios, which can reduce carbon emissions, lower environmental pollution, and at the same time have low operating noise, improving the working environment quality of logistics places such as warehouses or factories.

Moreover, if one or more sensors fail, the transport vehicle can still rely on other sensors to work normally, ensuring the continuity and safety of transportation tasks, not only improving the reliability of the transport vehicle but also reducing downtime and maintenance costs caused by sensor failures.

[0112] Embodiment 2:

[0113] Please refer to Figures 1 to 5 As shown, in order to improve logistics efficiency and reduce labor costs, a large e-commerce warehouse introduces an autonomous navigation intelligent logistics transport vehicle. This warehouse needs to process a large number of orders every day, including various goods from stationery to large household appliances. Traditional manually driven forklifts and trailers can no longer meet the requirements of fast and accurate cargo handling. In addition, the internal space of the warehouse is complex, with multiple narrow channels and shelves of different heights, posing high requirements for the flexibility and intelligence of transport vehicles.

[0114] Usage process:

[0115] First, warehouse management personnel install positioning beacons at key positions (such as entrances, exits, aisle between shelves, etc.) according to the warehouse layout to ensure that the intelligent logistics transport vehicle can accurately identify its own position.

[0116] Next, the technician connects the intelligent logistics transport vehicle to the remote server via the 5G network for initialization settings and path planning. According to the daily order processing flow, multiple optimal transport paths are preset.

[0117] The 16-line lidar and 32-line lidar mounted on the transport vehicle start to scan the environment to construct a high-precision three-dimensional map, providing environmental data support for autonomous driving.

[0118] When an order is generated, the warehouse management system automatically sends the order information to the remote server. The server assigns tasks to the intelligent logistics transport vehicle based on the order content and the location of the goods.

[0119] After receiving the task, the intelligent logistics transport vehicle automatically starts and travels to the designated shelf location according to the preset path. During the driving process, the camera captures visual information, which is fused with the lidar data to detect obstacles in real time and adjust the driving route to ensure safety.

[0120] After arriving at the shelf location, the transport vehicle controls the lifting of the transport platform through the hydraulic lifting power unit to smoothly load the goods onto the transport platform. After the goods are loaded, the transport vehicle travels to the next destination (such as the packing area, shipping area, etc.) according to the planned path.

[0121] During the entire transportation process, the management personnel can view the status, location, and task progress of the transport vehicle in real time through the remote monitoring interface and can perform manual intervention or adjust the task when necessary.

[0122] The intelligent logistics transport vehicle is equipped with a power monitoring system. When the power is lower than the set threshold, it will automatically go to the charging area for charging.

[0123] The warehouse management personnel regularly inspect and maintain the transport vehicle to ensure its normal operation. At the same time, they can also adjust and optimize the path planning and task allocation strategies according to the changes in the warehouse layout or new business requirements.

The traditional manual handling method is not only inefficient but also prone to errors. In addition, the space on the production line is limited, posing high requirements on the size and flexibility of the transport vehicle.

[0126] Usage process:

[0127] Enterprise technicians first install positioning beacons and sensors at key positions on the production line (such as material warehouses, production line entrances, workstations, etc.) to ensure that the intelligent logistics transport vehicle can accurately identify location and material information.

[0128] Next, connect to the intelligent logistics transport vehicle through the enterprise internal network to perform initialization settings and formulate task assignment strategies. According to the actual requirements of the production line and the material handling process, multiple optimal transport paths are preset.

[0129] When a material requirement is issued at a certain workstation on the production line, the management system automatically sends the requirement information to the intelligent logistics transport vehicle.

[0130] After receiving the requirement, the transport vehicle automatically starts and travels to the specified material warehouse location according to the preset path. During the driving process, the camera and lidar detect obstacles and pedestrians in real time to ensure safe driving.

[0131] After arriving at the material warehouse, the transport vehicle accurately finds the required materials through the identification system and loads the materials onto the transport platform through the hydraulic lifting power unit. After loading is completed, the transport vehicle travels to the required workstation according to the planned path.

[0132] After arriving at the workstation, the transport vehicle automatically unloads the materials to the specified location and waits for the next task instruction. During the entire transportation process, the management system monitors the status and task progress of the transport vehicle in real time to ensure the smooth operation of the production line.

[0133] Enterprise technicians regularly inspect and maintain the intelligent logistics transport vehicle, including detecting and adjusting aspects such as battery power, sensor sensitivity, and positioning accuracy.

[0134] As the production line changes and the material handling requirements change, technicians can also adjust and optimize the path planning and task assignment strategies of the transport vehicle. In addition, the functions of the transport vehicle can be upgraded and expanded according to actual requirements to improve its adaptability and flexibility.

[0139] Please refer to Figure 9 and Figure 10 In this embodiment, the logistics transport vehicle is a 220t intelligent logistics vehicle (axial hybrid IGV). The difference from Example One is that an axial hybrid structure is provided at the bottom of the transport vehicle body 1, including a six-axial drive group, where the 1st, 3rd, and 5th axles are hydraulic suspension drive systems, and the 2nd, 4th, and 6th axles are hydraulic suspension driven systems.

[0140] Working principle: The transport vehicle body is equipped with a 16-line lidar and a 32-line lidar, which together constitute the vehicle's environmental perception system. The lidar can scan the surrounding environment in real time, generate a high-precision three-dimensional map, and provide reliable environmental data support for autonomous driving.

[0141] At key positions in the warehouse (such as the entrance, exit, aisle between shelves, etc.), positioning beacons are installed. Through the interaction between the lidar and the positioning beacons, the transport vehicle can accurately identify its own position and ensure precise positioning in a complex environment.

[0142] The transport vehicle is equipped with a 5G autonomous driving control system, which conducts real-time data exchange with a remote server through 5G communication. Technicians can perform initialization settings and path planning on the transport vehicle through the remote server and preset multiple optimal transport paths.

[0143] When an order is generated, the warehouse management system automatically sends the order information to the remote server. The server assigns tasks to the intelligent logistics transport vehicle according to the order content and the location of the goods, and plans the optimal driving path.

[0144] After receiving the task, the transport vehicle automatically starts and travels to the designated shelf position according to the preset path. During the driving process, the camera captures visual information, fuses it with the lidar data, detects obstacles in real time, and adjusts the driving route to ensure safe driving.

[0145] A transport platform is fixed on the top of the transport vehicle for lapping the goods body. The transport platform realizes the lifting function through the coordinated action of hydraulic cylinders and telescopic rods to meet the loading and unloading requirements of goods at different heights.

[0146] After reaching the shelf position, the transport vehicle controls the lifting of the transport platform through the hydraulic lifting power unit, and smoothly loads the goods onto the transport platform. After the goods are loaded, the transport vehicle travels to the next destination according to the planned path.

[0147] Managers can view the status, location, and task progress of the transport vehicle in real time through the remote monitoring interface. When necessary, manual intervention or task adjustment can be carried out.

[0148] The transport vehicle is equipped with a power monitoring system. When the power is lower than the set threshold, it will automatically go to the charging area for charging.

[0149] Warehouse managers regularly inspect and maintain the transport vehicle to ensure its normal operation. At the same time, the path planning and task assignment strategies can also be adjusted and optimized according to changes in the warehouse layout or new business requirements.

[0150] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
