Description

Technical Field

[0001] This utility model relates to the field of shuttle vehicle technology, and in particular to an active avoidance device for optimizing supply chain shuttle vehicle paths. Background Technology

[0002] A supply chain shuttle is an intelligent robot primarily used in logistics and warehousing systems. It performs tasks such as picking, transporting, and placing goods, and communicates with a host computer or WMS system. Incorporating RFID, barcode, and other identification technologies, it achieves automated identification and retrieval functions. The shuttle is an intelligent handling robot that operates on a track, completing tasks such as goods entering and leaving the warehouse, inventory checks, and placement under system control. It can communicate with a host computer and WMS system, and uses electronic tags and barcodes for automatic identification and retrieval. The shuttle transports goods to designated locations or connecting equipment by running on a fixed track. Equipped with an intelligent sensing system, it can automatically remember its origin position and automatically decelerate.

[0003] Meanwhile, traditional shuttles generally employ passive obstacle avoidance during operation, which can easily lead to mission interruptions when encountering obstacles on their path. This is especially true in multi-shuttle collaborative environments; if one shuttle stops due to an obstacle, it can cause congestion or even paralysis of the entire system. Furthermore, the design of most traditional shuttles limits their movement to linear or limited-angle movements along fixed guide rails, preventing flexible adjustments in lateral displacement or attitude. While this operating mode ensures stability and predictability to some extent, it is less adaptable to complex conditions such as misaligned shelving, narrow aisles, equipment malfunctions, or temporary obstruction by other vehicles. Due to the lack of autonomous adjustment capabilities, shuttles often require manual intervention to resume normal operation, reducing automation levels and increasing maintenance costs and manpower burden. Utility Model Content

[0004] To overcome the limitations of traditional shuttle vehicles in terms of obstacle avoidance capabilities, which only allow for emergency stops or alarms when encountering obstacles, and the fixed operating path that makes it difficult to achieve flexible steering or position adjustments, this utility model provides an active obstacle avoidance device for supply chain shuttle vehicle path optimization.

[0005] The technical solution is as follows: An active obstacle avoidance device for supply chain shuttle path optimization includes a shuttle body; it also includes detection components and auxiliary components. The shuttle body surface is equipped with detection components for detecting whether there are obstacles in the running path and thus stopping the movement. Auxiliary components are installed on both sides of the shuttle body for rapid relocation when the shuttle position needs to be adjusted. The auxiliary components include a mounting frame, with the mounting frame fixedly connected to both sides of the shuttle body. A movable plate is installed in the center of the mounting frame. Electric push rods are threaded through both sides of the upper surface of the movable plate. A locking frame is installed at the piston end of the electric push rod, and a clamping plate is installed at the lower end of the locking frame. A movable wheel is clamped inside the clamping plate, and a rotating shaft connected to the movable wheel is threaded through the center of the clamping plate.

[0006] Furthermore, a fixing frame is fixedly connected to the upper end of the clamp, and a rotating frame connected to the fastening frame is installed at the center of the upper surface of the fixing frame.

[0007] Furthermore, sliding grooves are provided at the center of both sides of the mounting frame, and sliding rods are slidably connected inside the sliding grooves.

[0008] Furthermore, the sliding rod is fixedly connected to the movable plate, and a handle is fixedly connected to the top of the sliding rod.

[0009] Furthermore, the detection component includes moving wheels. Multiple sets of moving wheels are provided on the side surface of the shuttle body near the corner, and the moving wheels move along the guide rail.

[0010] Furthermore, a support frame is installed at the center of the upper surface of the shuttle vehicle, and a placement rack is installed at the upper end of the support frame.

[0011] Furthermore, the upper surface of the support frame is symmetrically provided with mounting slots on both sides corresponding to the placement racks, and multiple sets of mounting racks are installed on the upper surface of the support frame near the corners.

[0012] Furthermore, a motor is installed at the lower end of the mounting bracket, and an ultrasonic sensor is installed at the center of the upper surface of the mounting bracket.

[0013] The beneficial effects are: This utility model enables the shuttle car to move laterally and make fine adjustments to its posture by using movable wheels in conjunction with electric push rods. It can flexibly adjust its path in complex environments such as narrow spaces, misaligned shelves, or limited temporary passages, thereby improving operating efficiency. The detection components composed of ultrasonic sensors and multiple sets of mounting structures can achieve all-round environmental perception, monitor obstacles on the running path in real time, and react in a timely manner to effectively avoid collision accidents.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] Among the currently discovered feasible technologies, the following are described: Supply chain shuttles, as highly integrated intelligent handling robots, have become an indispensable core device in modern efficient warehousing and logistics systems. They not only possess basic functions such as picking, transporting, and placing goods, but also, under precise system control, can complete complex tasks such as goods entry and exit, inventory counting, and storage location adjustments along predetermined tracks. Through real-time data interaction with the host computer and warehouse management system (WMS), the shuttle can achieve intelligent scheduling and dynamic management of the entire warehousing process, significantly improving warehouse operation efficiency, reducing labor costs, and driving the warehousing system towards digitalization and informatization. In terms of technical architecture, supply chain shuttles integrate various advanced automatic identification and sensing technologies, such as RFID electronic tag reading and writing, and barcode scanning, enabling them to quickly and accurately identify goods information during operation, ensuring that every item is correctly stored, retrieved, located, and tracked. This high-precision information collection capability not only improves the system's automation level but also significantly reduces the error rate caused by manual operation, further enhancing the reliability and traceability of warehousing operations. Shuttle vehicles typically operate on fixed tracks laid within warehouses, offering excellent guidance and stability. They can flexibly transfer goods between different workstations and accurately deliver materials to designated locations according to task requirements. They can also seamlessly integrate with other logistics equipment such as conveyors, stacker cranes, and sorting systems to create an efficient internal logistics network. To ensure safe operation in complex environments, shuttle vehicles are equipped with a comprehensive intelligent sensing system, including infrared obstacle avoidance, lidar, and ultrasonic sensors. This system can perceive changes in the surrounding environment in real time, identify obstacles, and react promptly by slowing down, detouring, or stopping, effectively preventing collisions. Furthermore, shuttle vehicles possess several intelligent functions, such as the ability to automatically memorize their origin position. Even after a power outage or sudden malfunction, they can autonomously return to the initial station, preventing disruptions to subsequent operations due to lost location. Simultaneously, their control system supports an automatic deceleration mechanism, smoothly reducing speed when approaching target locations or turning areas, minimizing operational shock, improving positioning accuracy, and further enhancing stability and safety during operation. In the future, combined with emerging technologies such as artificial intelligence algorithms, 5G communication, and edge computing, shuttle vehicles will possess stronger autonomous decision-making and collaborative operation capabilities. They will not only be able to independently complete handling tasks but also form an efficient collaborative network with other AGVs, robots, and management systems, becoming a key component in building an unmanned and intelligent warehousing system. In conclusion, supply chain shuttle vehicles, with their high efficiency, intelligence, safety, and reliability, are profoundly changing traditional warehousing operation models, becoming an important supporting force for the upgrading and transformation of modern logistics systems, and providing a solid technological foundation for building an integrated platform for smart logistics and intelligent manufacturing.

[0018] Meanwhile, traditional shuttle buses generally employ a passive obstacle avoidance method during actual operation. When encountering obstacles on their path, they typically can only stop by emergency braking or trigger an alarm to notify staff. This response mechanism lacks flexibility and intelligence, resulting in a weak responsiveness to emergencies and easily causing task interruptions and process delays. Especially in environments with multiple shuttle buses operating collaboratively, if one shuttle bus stops due to an obstacle, it can cause congestion or even paralysis of the entire system, affecting overall operational efficiency and logistics rhythm.

[0019] Furthermore, the design of most traditional shuttles limits their movement to linear or limited-angle motion along fixed guide rails, preventing flexible adjustments in lateral displacement or posture. While this operational mode offers some stability and predictability, making it suitable for highly standardized warehousing environments, it struggles with complex situations such as misaligned shelving, narrow aisles, equipment malfunctions, or temporary obstruction by other vehicles. Lacking autonomous adjustment capabilities, shuttles often require manual intervention to resume normal operation, reducing automation levels, increasing maintenance costs and manpower, and limiting the potential for higher levels of intelligence in warehousing systems. More importantly, these limitations of traditional shuttles are amplified in high-density, high-frequency logistics operations. For example, when access is restricted in an area due to equipment maintenance or sudden malfunctions, traditional shuttles struggle to automatically detour or adjust their routes, requiring manual rescheduling. This not only prolongs operation time but can also lead to resource waste and efficiency reduction in upstream and downstream processes.

[0020] like Figures 1-5 As shown, the active obstacle avoidance device for supply chain shuttle path optimization includes a shuttle body 1; it also includes detection components and auxiliary components. The surface of the shuttle body 1 is provided with detection components for detecting whether there are obstacles in the running path and stopping the movement accordingly. The sides of the shuttle body 1 are equipped with auxiliary components for quick relocation when the shuttle position needs to be adjusted. The auxiliary components include a mounting frame 301, which is fixedly connected to both sides of the shuttle body 1. A movable plate 306 is installed in the center of the mounting frame 301. Electric push rods 302 are provided through both sides of the upper surface of the movable plate 306. A fastening frame 307 is installed at the piston end of the electric push rod 302. A clamping plate 310 is installed at the lower end of the fastening frame 307. A movable wheel 311 is clamped and installed inside the clamping plate 310. A rotating shaft 312 connected to the movable wheel 311 is provided through the center of the clamping plate 310.

[0021] A fixed bracket 309 is fixedly connected to the upper end of the clamping plate 310. A rotating bracket 308, connected to the fastening bracket 307, is installed at the center of the upper surface of the fixed bracket 309. This enhances the structural stability of the auxiliary component while allowing for flexible rotation at a certain angle, improving adaptability during obstacle avoidance. Sliding grooves 305 are provided at the center of both sides of the mounting frame 301, with sliding rods 304 slidably connected inside the sliding grooves 305. The sliding grooves 305 provide guidance and limiting functions for the movable component, ensuring smooth and controllable auxiliary movement. The sliding rods 304 are fixedly connected to the movable plate 306, and a handle 303 is fixedly connected to the top of the sliding rods 304. The handle 303 is designed for easy manual operation and maintenance, improving the convenience and maintainability of the device.

[0022] When the shuttle is in operation, its surface detection components continuously monitor the path for obstacles and trigger a response mechanism upon detecting any anomalies. At this point, the auxiliary components come into play. Movable plates 306 are installed inside the mounting frames 301 on both sides of the shuttle. These plates, driven by electric push rods 302, move up and down the fastening frame 307, causing the clamping plate 310 and its movable wheels 311 to adjust their height. When the movable wheels 311 contact the ground, they bear part of the shuttle's weight and can steer flexibly using the pivot 312 at the center of the clamping plate 310. The fixed frame 309 connected to the upper end of the clamping plate 310 works in conjunction with the rotating frame 308 to ensure the entire auxiliary structure remains stable while possessing a certain degree of rotational freedom, thus adapting to obstacle avoidance requirements at different angles. Simultaneously, the sliding grooves 305 on both sides of the mounting frame 301 cooperate with the sliding rods 304 to guide and support the raising and lowering of the movable plates 306, ensuring smooth and reliable operation.

[0023] Please see Figures 3-4 The detection components include movable wheels 201. Multiple sets of movable wheels 201 are located on the side surface of the shuttle body 1 near the corners, and the movable wheels 201 move along the guide rail 4. The distribution of multiple sets of movable wheels 201 improves the stability and guiding accuracy of the shuttle operation, ensuring its smooth movement on the guide rail 4. A support frame 202 is installed at the center of the upper surface of the shuttle body 1, and a placement rack 206 is installed on the upper end of the support frame 202. The combination of the support frame 202 and the placement rack 206 enhances the load-bearing capacity and provides a stable transportation platform for goods. The upper surface of the support frame 202 has symmetrically opened mounting slots 207 corresponding to the placement rack 206 on both sides, and multiple sets of mounting racks 204 are installed on the upper surface of the support frame 202 near the corners. The design of mounting slot 207 and mounting bracket 204 improves the modularity of the structure, making it easier to assemble, position and expand functions. A motor 203 is installed at the lower end of the mounting bracket 204, and an ultrasonic sensor 205 is installed at the center of the upper surface of the mounting bracket 204. The motor 203 drives the ultrasonic sensor 205 to realize dynamic environmental perception, providing technical support for path detection and obstacle avoidance.

[0024] During operation, the shuttle travels along the guide rail 4 via multiple sets of movable wheels 201 positioned near the corners on its side surface. These evenly distributed wheels ensure smoother movement of the shuttle on the rail, effectively improving guidance accuracy and reducing the risk of deviation or jamming. Simultaneously, the support frame 202 mounted at the center of the shuttle's upper surface, together with the placement rack 206, provides a stable transport platform for the carried goods, ensuring safety and reliability during transport. The support frame 202 has mounting slots 207 on both sides that match the placement rack 206, resulting in tighter structural connections, facilitating rapid assembly and positioning, and also reserving interfaces for future functional expansion. Multiple mounting racks 204 located at the corners of the support frame 202 are equipped with motors 203 at their lower ends to drive related components. Ultrasonic sensors 205 are mounted on the upper part of the mounting racks 204, enabling real-time sensing of environmental changes during operation, timely identification of obstacles, and data support for path adjustment.
