Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics distribution, especially to an intelligent logistics trolley with dynamically adjusted identification area. BACKGROUND

[0002] With the rapid development of the logistics industry, automation and intelligent equipment are increasingly widely used in warehouse management and cargo distribution. Intelligent logistics trolleys, as an important part of modern logistics systems, are favored for their high flexibility, cost-effectiveness, and other characteristics. However, traditional logistics trolleys usually rely on fixed path planning and limited environmental perception capabilities, which limits their adaptability and efficiency in complex and changing work environments.

[0003] Although existing intelligent logistics trolleys can achieve autonomous navigation to some extent, they often cannot quickly scan and identify cargo and intersection identification distribution point codes using scanning devices, leading to information reading delays that result in longer logistics operation times and lower logistics efficiency. In addition, when faced with dynamically changing environments, such as changes in cargo location or the appearance of new distribution points, manual intervention is often required to adjust the path or reset the task. The above-mentioned defects are problems that need to be solved by those skilled in the art. SUMMARY

[0004] To overcome the deficiencies in the background art, the utility model discloses an intelligent logistics trolley with dynamically adjusted identification area, which not only automatically adapts to different working environments, improving delivery efficiency and accuracy, but also enhances the stability and maintainability of the system by optimizing the internal structure and introducing advanced control modules.

[0005] To achieve the above-mentioned purposes, the utility model adopts the following technical solutions:

In addition, upper top plate 1-1 and lower bottom plate 1-2 jointly constitute a protection frame, effectively prevent external impact from causing damage to mobile power supply 5 and main controller 2. When selecting main controller, microcontroller based on STM32F103RCT6 can be used, which has good performance and stability.

[0037] Upper top plate 1-1 not only serves as a platform for carrying goods, but also has a square hollow material box 1-9 on its top. Such design increases the stability during goods transportation, reduces the risk of goods sliding due to vibration or inclination.

[0038] The bottom of lower bottom plate 1-2 is equipped with two walking wheels 1-4 driven by motor, and the other end is provided with universal wheel 1-5, as shown in the drawings Figure 3 The diameters of the two walking wheels 1-4 are 65mm, and direct current reduction motor MG531 is selected as power source. They are controlled by main controller 2, and realize flexible steering by adjusting the differential between the two wheels and universal wheel 1-5. This combination enables trolley chassis 1 to move freely in a limited space, such as narrow aisles in small supermarkets or narrow spaces in warehouses.

[0039] The image recognition module 4 is installed on the top of one end of the trolley chassis 1, and the tracking module 3 is installed on the bottom of the same end. Both the image recognition module 4 and the tracking module 3 are signal-connected with the main controller 2 to realize data transmission. Among them:

[0040] The image recognition module 4 is used to automatically adjust the recognition area, obtain the information of the goods and the target distribution point, and feed back the information to the main controller 2. At the starting point, the image recognition module 4 will automatically adjust its recognition range, capture the required information and transmit it to the main controller 2, thereby starting the entire transportation process.

The following is a specific introduction to the new components:

[0045] The camera module 4-1 selects the openMV module with high cost performance, which meets the technical requirements while reducing costs. In order to better adapt to different application scenarios, the camera module 4-1 is equipped with a special angle height adjusting mechanism.

[0046] As shown in the attached Figure 5 , the angle height adjusting mechanism includes a stand 4-2, a height adjusting plate 4-3, a damping shaft 4-4, and a fixed plate 4-5. Specifically:

[0047] The stand 4-2 is firmly connected to the trolley chassis 1, providing stable support.

[0048] The height adjusting plate 4-3 is designed to be adjustable in height between the stand 4-2, allowing users to adjust the height of the camera according to actual needs.

[0049] Damping shaft 4-4: connects the height adjustment plate 4-3 and the fixed plate 4-5, allowing the angle of the camera to be freely adjusted, and can lock the position after the adjustment is completed to ensure that the shooting angle remains stable.

[0050] Fixed plate 4-5: used to install the camera module 4-1 to ensure that it is installed firmly and reliably.
