[0001] The utility model relates to the technical field of intelligent logistics, in particular to an AGV base for warehousing logistics. Background Art

[0002] Intelligent logistics aims to make a large amount of operations and decision-making in the logistics process intelligent; with logistics management as the core, it realizes the integration of transportation, storage, packaging, loading and unloading and the hierarchical intelligent logistics system.

[0003] Current intelligent warehouse logistics mostly relies on ground rails or AGVs. However, the existing AGV base structure is relatively simple, mostly four-wheeled. This structure has the problem of shaking when towing large-volume cargo, which indirectly causes the cargo to roll over and affects transportation efficiency. Therefore, we propose an AGV base for warehouse logistics to solve the above problems. Utility Model Content

[0006] Furthermore, the driving component includes a servo motor and a reducer. The reducer is fixed to the inner wall of the box with bolts. One end of the reducer is coaxially fixed to the center of the walking wheel, and the other end is coaxially fixed to the output end of the servo motor. The servo motor is inverted.

[0007] Furthermore, the lifting member includes a servo cylinder, a fixing rod and a limiting bolt. The fixing rod is transversely fixed to the inner wall of the box. The bottom end of the servo cylinder is mounted on the fixing rod through a connecting sleeve and is limited by the limiting bolt thread.

[0008] Furthermore, each of the boxes includes two lifting members that are symmetrical about the center of the box.

[0009] Furthermore, the support block is a bent sheet metal part, one end of which is hooked to the output end of the servo cylinder through a hook, and the other end is flat and has a positioning hole for connecting to an external carrying box.

[0010] Furthermore, the base is formed by welding two channel steels and has a raised center to separate the two boxes.

[0011] Furthermore, a panel is fixed at one end of the base, and the panel is connected to the ends of the two channel steels to form a space for accommodating the external terminal block. A power support plate is also fixed at intervals on the top of the panel, and the two ends of the power support plate are bent upward and a wire passing opening is opened in the center, and the hollow is fixed on the top of the panel.

[0012] Compared with the existing technology, the beneficial effects of the present invention include: through the two large walking wheels and the universal wheels at the four corners of the bottom, the cargo towing and transportation process is more stable and not prone to shaking. At the same time, the towing part is hollowed out with a lifting part to further ensure the stability of the cargo.

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, a person skilled in the art can propose a variety of interchangeable structural methods and implementation methods. Therefore, the following specific embodiments and drawings are only illustrative of the technical solution of the present invention and should not be regarded as the entire present invention or as a limitation or restriction of the technical solution of the present invention.

[0020] According to one embodiment of the present invention, Figure 1-Figure 4 Shown.

[0021] As for the overall structure, in this embodiment, an AGV base for warehousing and logistics includes: a base 1, universal wheels 2 are provided at the four corners of the bottom of the base 1, and a box 3 with a cavity inside is vertically fixed on the top thereof, a driving part and a lifting part are fixed in the box 3, the box 3 includes two and is symmetrical on both sides of the middle position of the base 1, each of the boxes 3 is rotatably connected to a walking wheel 4 at one end on the outside of the corresponding base 1, a through hole 5 is provided on the top of the box 3 and a support rod 6 is slidably connected in the through hole 5, the lifting part is fixed to the inner bottom of the box 3, and its output end is coaxially fixed with the bottom end of the support rod 6, the top of the support rod 6 is exposed outside the box 3 and a support block 7 is fixed at the exposed end, and the support rod 6 includes at least two and is symmetrical about the center of the base 1.

[0022] The specific selection of the driving member and the lifting member can actually include various forms. In this embodiment, for example Figure 4 As shown, a servo motor 8 and a servo cylinder 10 are used. Specifically, the driving component includes a servo motor 8 and a reducer 9. The reducer is fixed with bolts to the inner wall of the box 3. One end of the reducer is coaxially fixed to the center of the walking wheel 4, and the other end is coaxially fixed to the output end of the servo motor 8. The servo motor 8 is inverted.

[0023] After the servo motor 8 outputs, it can synchronously drive the two large walking wheels 4 to rotate, and then cooperate with the four universal wheels 2 at the four corners of the bottom of the base 1 to rotate. This walking method avoids the limitations of the conventional four-wheel type, and the center of gravity can be kept at the lowest during the walking process, which is stable and reliable.

[0024] The lifting member includes a servo cylinder 10, a fixing rod 11, and a limiting bolt 12. The fixing rod 11 is transversely fixed to the inner wall of the box 3. The bottom end of the servo cylinder 10 is mounted on the fixing rod 11 via a connecting sleeve and is threadedly limited by the limiting bolt 12. There are two lifting members in each box 3, and they are symmetrical about the center of the box 3.

[0025] Furthermore, the support block 7 is a bent sheet metal part, one end of which is hooked with the output end of the servo cylinder 10 through a hook 13, and the other end is flat and has a positioning hole 14 for connecting to an external carrying box.

[0026] Through the above structure, the servo cylinder 10 is positioned by the limit bolt 12 and the fixing rod 11, and a bent support block 7 is fixed on the top to connect the external carrying box for towing goods. This hollow fixing method can minimize the impact of the base shaking during walking on the goods.

[0027] Similarly, the base 1 is constructed from two welded channel steels with a raised center to separate the two boxes 3. A panel 15 is fixed to one end of the base 1. This panel 15 connects with the ends of the two channel steels to form a space for accommodating the external terminal blocks. A power supply support plate 16 is fixed to the top of the panel 15 at intervals. The two ends of the panel are bent upward, and a wire-passing opening 17 is defined in the center. The hollow portion is fixed to the top of the panel 15.

[0028] The power supply support plate 16 can be fixed in a hollow manner, indirectly ensuring the hollow suspension of the power supply, and the terminal block can be placed internally between the enclosure 15 and the channel steel, ensuring airtightness while also enabling wire connection through the corresponding wire holes, which is convenient and reliable.

[0029] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the scope of protection of the present invention.
