Description

Technical Field

[0001] This utility model relates to the field of intelligent warehousing robot technology, and more specifically, to a multi-directional mobile chassis for intelligent warehousing robots. Background Technology

[0002] With the rapid development of e-commerce, intelligent manufacturing and other industries, the warehousing and logistics industry has ushered in explosive business growth, which has put forward higher requirements for the automation and intelligence level of warehousing operations. As the core equipment for realizing precise handling, efficient sorting and intelligent scheduling of goods, the mobility performance of intelligent warehousing robots directly determines the overall operating efficiency, space utilization and operating costs of the warehousing system.

[0003] Traditional intelligent warehousing robots typically employ unidirectional drive (e.g., front-wheel drive with rear-wheel follow) or bidirectional drive (e.g., independent front and rear wheel drive) structures. Their movement direction is limited by the chassis's mechanical design, usually only allowing for linear motion in the forward or backward direction and turning movements with a fixed radius. In actual warehousing operations, these chassis have significant limitations: First, in narrow aisles or densely packed shelving areas, the robot needs to adjust its direction multiple times to complete turning or cargo docking actions, not only extending the single operation time but also increasing the risk of collisions with surrounding shelves, goods, or other robots. Second, for scenarios requiring lateral cargo transfer (e.g., docking with side-opening shelves, cross-aisle transfer), traditional chassis cannot achieve direct lateral movement.

[0004] To avoid the aforementioned problems, current intelligent warehousing robots on the market all utilize a corresponding number of Mecanum wheels mounted on their bottom mobile chassis, with independent servo motors controlling the Mecanum wheels to achieve multi-directional movement. For example, invention patent CN116000918A discloses a multi-functional composite robot based on an omnidirectional mobile AGV chassis, including an omnidirectional mobile AGV chassis, an electronic control system, a collaborative robot system, a vision inspection system, a rotary quick-change system, and a tool magazine. The omnidirectional mobile AGV chassis can move in all directions and rotate with zero turning radius. The electronic control system is mounted above the omnidirectional mobile AGV chassis; the collaborative robot system is mounted above the electronic control system; the vision inspection system is mounted at the end of the collaborative robot system; the rotary quick-change system is mounted on the upper left of the electronic control system; and the tool magazine is mounted on the upper right of the electronic control system. A barcode reader in the tool magazine is used to read tool information stored in data screws. This invention enables automated detection and replacement of tool wear in machining centers, as well as the transfer of machine tools, tool magazines, and tool adjustment rooms, and the loading and unloading of cylindrical workpieces without human intervention.

[0005] While the aforementioned technical solutions have their advantages, most current multi-directional mobile chassis using Mecanum wheels still have some shortcomings in use. For example, the Mecanum wheel area lacks corresponding components to block impurities from the bottom surface, making it easy for impurities to enter the Mecanum wheel area and get stuck in the Mecanum wheel's pivot point, affecting the normal rotation of the Mecanum wheel. Therefore, we propose a multi-directional mobile chassis for intelligent warehousing robots. Utility Model Content

[0006] The purpose of this invention is to provide a multi-directional mobile chassis for intelligent warehousing robots to address the deficiencies mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The multi-directional mobile chassis of the intelligent warehousing robot includes an AGV chassis body and multiple Mecanum wheels set at the bottom of the AGV chassis body. A wheel protective cover is fixedly installed on the bottom surface of the AGV chassis body and fitted over the multiple Mecanum wheels. A blowing assembly for blowing air outward from the inside of the Mecanum wheels is provided on the AGV chassis body. An impurity blocking assembly for preventing impurities from entering the Mecanum wheel area is fixedly installed at the bottom of the wheel protective cover.

[0008] Preferably, a loading platform is fixedly installed on the top surface of the AGV chassis body, and the loading platform is used for the installation and operation of the intelligent warehousing robot robotic arm.

[0009] Preferably, the air blowing assembly includes an air inlet hood fixedly installed on the side of the AGV chassis body and a uniformly distributed ring pipe fixedly installed on the bottom surface of the AGV chassis body. A small fan is installed inside the air inlet hood. The uniformly distributed ring pipe is connected to the air inlet hood through an air outlet pipe. The uniformly distributed ring pipe has multiple air outlet holes on its body. The air outlet holes are located inside the corresponding Mecanum wheel. The air outlet holes are used to blow air from the inside to the outside of the Mecanum wheel. This setting allows air to blow from the inside out of the Mecanum wheel, removing impurities from the Mecanum wheel and preventing them from getting stuck and affecting its normal rotation.

[0010] Preferably, a plurality of fixing rings are fixedly installed on the annular side of the air inlet shroud, and the fixing rings are detachably installed on the rear side of the AGV chassis body; This feature facilitates the fixed installation of the air inlet cover.

[0011] Preferably, an impurity baffle is provided at the end of the air inlet hood, and a support ring is fixedly installed on the annular side of the impurity baffle. The support ring is detachably installed on the end face of the air inlet hood. This setting can filter dust from the air intake.

[0012] Preferably, a plurality of fixed supports are fixedly installed on the top of the uniformly distributed ring pipe, and the fixed supports are detachably installed on the bottom surface of the AGV chassis body; This feature facilitates the fixed installation of the uniformly distributed ring pipe.

[0013] Preferably, the impurity blocking assembly includes a fixing strip detachably mounted on the bottom surface of the wheel guard, and the bottom surface of the fixing strip is provided with blocking bristles; This setting can further prevent impurities from entering the Mecanum wheel area by using barrier bristles.

[0014] Preferably, the number of fixing strips is four, and the four fixing strips form a rectangular ring structure.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model involves fixing a wheel cover around multiple Mecanum wheels at the bottom of the AGV chassis body, and setting an impurity blocking component at the bottom of the wheel cover. The impurity blocking component uses detachable fixing strips and a bottom blocking bristle structure, and the four fixing strips form a rectangular ring structure. This achieves the effect of blocking ground impurities from all directions outside the Mecanum wheels, effectively preventing dust, debris and other impurities from directly entering the Mecanum wheel part, reducing the risk of impurities getting stuck in the shaft from the source, and ensuring the smooth rotation of the Mecanum wheels.

[0016] 2. This utility model sets up a blowing component on the main body of the AGV chassis. It uses a small fan in the air inlet hood to provide airflow, which is then delivered to a uniformly distributed ring pipe located inside the Mecanum wheel through the air outlet pipe. The airflow is then blown from the inside out through multiple air outlets on the uniformly distributed ring pipe, achieving an active cleaning effect on the inner side and surrounding area of ​​the Mecanum wheel. This can promptly blow away small impurities that may be attached to the wheel or shaft, further reducing the probability of failure caused by impurity accumulation and ensuring the continuous and stable operation of the multi-directional mobile chassis.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a multi-directional mobile chassis for an intelligent warehousing robot, including an AGV chassis body 1 and multiple Mecanum wheels 10 disposed at the bottom of the AGV chassis body 1. A wheel protective cover 12 is fixedly installed on the bottom surface of the AGV chassis body 1, covering the multiple Mecanum wheels 10. A blower assembly 2 is provided on the AGV chassis body 1 for blowing air outward from the inside of the Mecanum wheels 10. An impurity blocking assembly 3 is fixedly installed at the bottom of the wheel protective cover 12 for blocking impurities from entering the Mecanum wheels 10. Under the basic protection of the wheel protective cover 12, the internal blowing cleaning of the blower assembly 2, and the bottom blocking effect of the impurity blocking assembly 3, the Mecanum wheels 10 at the bottom of the AGV chassis body 1 can effectively prevent impurities from entering the Mecanum wheels 10, ensuring the normal rotation of the Mecanum wheels 10 and improving the overall reliability of the multi-directional mobile chassis.

[0020] like Figure 1 As shown, a loading platform 11 is fixedly installed on the top surface of the AGV chassis body 1. The loading platform 11 is used for the installation and operation of the intelligent warehousing robot's robotic arm, so that the robotic arm of the intelligent warehousing robot can be stably installed on the loading platform 11, providing a solid installation foundation for the robotic arm to carry out operations such as cargo handling and sorting, ensuring the stability of the robotic arm and the chassis working together, and indirectly improving the efficiency of warehousing operations.

[0021] like Figures 1-3As shown, the blowing assembly 2 includes an air inlet hood 20 fixedly installed on the side of the AGV chassis body 1 and a uniformly distributed ring pipe 24 fixedly installed on the bottom surface of the AGV chassis body 1. A small fan 21 is installed inside the air inlet hood 20. The uniformly distributed ring pipe 24 is connected to the air inlet hood 20 through an air outlet pipe 23. Multiple air outlet holes 241 are provided on the pipe body of the uniformly distributed ring pipe 24. The air outlet holes 241 are located inside the corresponding Mecanum wheel 10. The air outlet holes 241 are used to blow air from the inside to the outside of the Mecanum wheel 10, so that the air force generated by the small fan 21 can be delivered to the uniformly distributed ring pipe 24 through the air outlet pipe 23, and then blow air from the inside to the outside of the Mecanum wheel 10 through the air outlet holes 241 to blow away impurities in the Mecanum wheel 10 and prevent impurities from getting stuck in the Mecanum wheel 10 and affecting its normal rotation.

[0022] In this embodiment, multiple fixing rings 201 are fixedly installed on the annular side of the air inlet hood 20. The fixing rings 201 can be detachably installed on the rear side of the AGV chassis body 1, so that the staff can easily install the air inlet hood 20 on the AGV chassis body 1 through the fixing rings 201, or quickly disassemble the air inlet hood 20 when maintenance is required, which simplifies the installation and maintenance operation process of the air inlet hood 20.

[0023] Specifically, an impurity baffle 221 is provided at the end of the air inlet hood 20. A support ring 22 is fixedly installed on the annular side of the impurity baffle 221. The support ring 22 is detachably installed on the end face of the air inlet hood 20, so that when the air inlet hood 20 draws in air, the impurity baffle 221 can filter dust and other impurities in the air, preventing impurities from entering the blower assembly 2 with the airflow and causing blockage. At the same time, the detachable design of the support ring 22 makes it easy to periodically remove the impurity baffle 221 for cleaning or replacement.

[0024] Furthermore, multiple fixed supports 25 are fixedly installed on the top of the uniformly distributed ring pipe 24. The fixed supports 25 can be detachably installed on the bottom surface of the AGV chassis body 1, so that the uniformly distributed ring pipe 24 can be stably fixed on the bottom surface of the AGV chassis body 1 through the fixed supports 25, avoiding displacement of the uniformly distributed ring pipe 24 during chassis movement. At the same time, the detachable design facilitates subsequent inspection, maintenance or replacement of the uniformly distributed ring pipe 24.

[0025] like Figure 1 and Figure 4 As shown, the impurity blocking component 3 includes a fixing strip 30 that is detachably mounted on the bottom surface of the wheel guard 12. The bottom surface of the fixing strip 30 is provided with blocking bristles 31, which allows the bottom of the wheel guard 12 to further block impurities on the ground from entering the Mecanum wheel 10 through the blocking bristles 31. At the same time, the detachable design of the fixing strip 30 makes it easy to replace the blocking bristles 31 after they wear out, ensuring the continuity of the impurity blocking effect.

[0026] It is worth noting that there are four fixing strips 30, which form a rectangular ring structure, enabling the impurity blocking component 3 to form an all-round ring barrier around the Mecanum wheel 10, blocking impurities from entering from all sides. Compared with a single-direction blocking structure, this further improves the comprehensiveness and effectiveness of impurity blocking.

[0027] Finally, it should be noted that the Mecanum wheel 10, the corresponding servo motor, the servo system, and the corresponding control system of this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the adapted controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0028] When using the multi-directional mobile chassis of the intelligent warehousing robot of this utility model, first check whether the Mecanum wheels 10 at the bottom of the AGV chassis body 1 are flexible, whether the wheel protective covers 12 are loose, and whether the blocking brush bristles 31 on the fixing strip 30 in the impurity blocking assembly 3 are intact. At the same time, remove the end support ring 22 of the air inlet cover 20, clean the dust on the impurity blocking net 221, and then reinstall it. Next, fix the intelligent warehousing robot arm on the loading platform 11 on the top surface of the AGV chassis body 1 to ensure that the installation is stable. During operation, the equipment is started, and the blowing assembly 2 on the AGV chassis body 1 operates synchronously. The small fan 21 in the air inlet hood 20 draws in air, which is then delivered to the uniformly distributed ring pipe 24 through the air outlet pipe 23. The air is then blown out through the air outlet 241 on the uniformly distributed ring pipe 24 corresponding to the inner side of the Mecanum wheel 10, blowing away impurities near the wheel body. At the same time, the bristles 31 of the impurity blocking assembly 3 at the bottom of the wheel protection cover 12 prevent ground impurities from entering. The Mecanum wheel 10 drives the chassis to move flexibly, cooperating with the robotic arm to complete the cargo handling and sorting operations. After operation, shut down the equipment. If maintenance of the air inlet hood 20 is required, the air inlet hood 20 can be removed through the fixing ring 201. If the bristles 31 are worn, the fixing strip 30 can be removed and replaced to ensure that all structures of the chassis operate normally during the next operation.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
