Description

Technical Field

[0001] The present invention relates to the technical field of intelligent logistics equipment, and particularly relates to an anti-collision and shock-resistant intelligent logistics pallet. Background Art

[0002] With the development of the logistics industry towards automation and intelligence, the demand for intelligent pallets integrated with sensors and communication modules has surged. Intelligent pallets integrated with sensors and communication modules have become the core equipment for automated warehousing and transportation. In practical applications, intelligent pallets are also often faced with extreme temperature differences in cross-border logistics warehousing and inevitable collisions between multiple pallets. Nowadays, the protection performance and maintenance convenience of intelligent pallets in complex logistics environments have become the key pain points restricting industrial upgrading.

[0003] However, traditional pallets mostly use wooden structural stiffeners or elastic rubber buffer layers for anti-collision, mainly relying on structural design to buffer impacts, with limited protection effects and prone to causing damage to goods. Existing intelligent pallets are integrated with precision hardware such as RFID, GPS, and acceleration sensors, and usually adopt traditional fixing methods, which cannot meet the requirements of complex working conditions and are easily damaged by vibration and impact. There are also some intelligent pallets that use non-Newtonian fluids to improve the anti-impact ability of the pallets, but non-Newtonian fluids have significant performance fluctuations in logistics warehouses with large day-night temperature differences. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems and propose an anti-collision and shock-resistant intelligent logistics pallet.

[0005] To achieve the above purpose, the following technical solutions are adopted: An anti-collision and shock-resistant intelligent logistics pallet, including a pallet body and a hardware intelligent module. The pallet body is provided with a first stiffener, and a plurality of support column feet are integrally provided on the pallet body. Anti-collision modules are provided on the support column feet at the four corners of the pallet body. A first buffer groove is provided inside the anti-collision module, and a second stiffener is provided in the first buffer groove. Non-Newtonian fluid is filled in the gaps between the second stiffeners; a protection cavity is provided inside the support column feet, and a hardware protection cabin for installing the hardware intelligent module and mutually staggered third stiffeners are provided in the protection cavity. Non-Newtonian fluid is filled in the gaps of the third stiffeners, and the hardware intelligent module is inserted into the hardware protection cabin from the side of the pallet body.

[0006] Furthermore, at least one fixing groove is provided on the support column feet at the four corners, at least one fixing pin is provided on the anti-collision module, a jack is provided on the fixing pin, and a plug pin is provided in the jack.

[0007] Furthermore, a metal rod is provided inside the bolt. The head of the bolt is a conical plug, and the tail of the bolt is a limiting protrusion.

[0008] Furthermore, the second reinforcing ribs intersect with each other to form a hexagonal honeycomb structure. Micropores are provided on the reinforcing ribs at the bottom edge of the hexagon, and the honeycomb-shaped second reinforcing ribs are connected through the first micropores.

[0009] Furthermore, a liquid inlet for filling non-Newtonian fluid is provided above the anti-collision module, and a plug matching the liquid inlet is provided in the liquid inlet.

[0010] Furthermore, the third reinforcing ribs intersect with each other to form a rhombus structure, and second micropores are provided on the rhombus structure third reinforcing ribs.

[0011] Furthermore, a groove is provided at the exit of the hardware protection cabin, a magnetic attraction component is provided in the groove, and a buffer pad is provided in the hardware protection cabin.

[0012] Furthermore, the non-Newtonian fluid is a shear thickening non-Newtonian fluid, and the preparation steps of the non-Newtonian fluid are as follows: S1: Stir and mix polyethylene glycol and silicone oil at 50-60 °C for 25-35 min. After stirring is completed, add glycerol and continue stirring for 10-20 min to obtain mixture A; S2: Add the hydrolyzed silane coupling agent to mixture A, continue stirring for 20-30 min, and then add nano-silica in multiple batches while stirring evenly until the powder is completely dispersed to obtain mixture B; S3: Add an antioxidant to mixture B and continuously heat up to 75-80 °C, continue stirring for 55-70 min to obtain mixture C; S4: Perform vacuum degassing treatment on mixture C for 25-35 min, and obtain the non-Newtonian fluid after cooling to room temperature.

[0013] Furthermore, in step S2, the silane coupling agent is diluted with a mixed solution of ethanol and water in a ratio of 1:5 and hydrolyzed at room temperature for 5-10 min, and the hydrolyzed silane coupling agent is added to mixture A.

[0014] Furthermore, the non-Newtonian fluid is a shear thickening non-Newtonian fluid, and the basic raw materials of the non-Newtonian fluid include 40-50% nano-silica, 40-50% polyethylene glycol, 5-10% silicone oil, 0.5% antioxidant. In addition, 10-15% glycerol by mass of the non-Newtonian fluid and 3-5% silane coupling agent by mass of the non-Newtonian fluid are added.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By setting the second reinforcing rib of the honeycomb structure and filling non-Newtonian fluid into its voids, the shear performance of the non-Newtonian fluid is utilized to relieve the impact received by the anti-collision module, transfer the impact force to the second reinforcing rib, and then further disperse the energy by virtue of the honeycomb structure of the reinforcing rib, forming a multi-level protection, improving the anti-collision performance and impact resistance of the tray, and avoiding damage to the tray and the goods due to collision.

[0016] Cover the hardware protection cabin with the third reinforcing rib of the diamond structure, relieve the impact force through the non-Newtonian fluid, and cooperate with the buffer pad inside the hardware protection cabin to further protect the hardware intelligent module, preventing damage to the hardware intelligent module, which may lead to data loss or errors and cannot meet the scheduling requirements of the automated warehousing and transportation system.

[0017] Fix the anti-collision module through the mortise and tenon structure, enable the anti-collision module to be quickly replaced, improve the stability of the structure, reduce the maintenance cost, and improve the maintenance efficiency.

[0020] The following specifically describes an anti-collision and anti-impact intelligent logistics pallet of the present invention with reference to the accompanying drawings.

[0021] Combined with Figures 1 to 9 As shown, an anti-collision and anti-impact intelligent logistics pallet includes a pallet body 1 and a hardware intelligent module 2. A first reinforcing rib 11 is provided on the pallet body 1, and a plurality of supporting column feet 12 are integrally provided on the pallet body 1. Anti-collision modules 3 are provided on the supporting column feet 12 at the four corners of the pallet body 1. A first buffer groove 31 is provided inside the anti-collision module 3, and a second reinforcing rib 32 is provided in the first buffer groove 31. Non-Newtonian fluid is filled in the gap between the second reinforcing ribs 32. The pallet body 1 improves the overall stiffness through the first reinforcing rib 11 to resist deformation during transportation; the integral supporting column feet 12 provide a stable load-bearing foundation. The first buffer groove 31 and the second reinforcing rib 32 are arranged inside the anti-collision modules 3 at its four corners. The latter forms a honeycomb structure, and the gap is filled with non-Newtonian fluid. When impacted, the fluid instantaneously hardens due to the shear thickening effect, and combined with the mechanical conduction path of the reinforcing rib, the impact force is dispersed and converted into internal energy. During use, first fill the anti-collision module 3 with non-Newtonian fluid, and then set the anti-collision module 3 filled with non-Newtonian fluid on the pallet body 1 to enhance the anti-collision performance of the pallet and protect the four corners of the pallet that are most vulnerable to collision.

[0022] Furthermore, the surface of the second reinforcing rib 32 with a honeycomb structure is coated with silicone rubber, which can alleviate the influence of large temperature differences in the logistics warehouse on the second reinforcing rib 32 and the non-Newtonian fluid.

[0023] As Figure 6 shown, a protection cavity 13 is provided inside the supporting column foot 12. A hardware protection cabin 4 for installing the hardware intelligent module 2 and mutually intersecting third reinforcing ribs 41 are provided in the protection cavity 13. Non-Newtonian fluid is filled in the gap of the third reinforcing ribs 41. The hardware intelligent module 2 is inserted into the hardware protection cabin 4 from the side of the pallet body 1. The protection cavity 13 inside the supporting column foot 12 integrates the hardware protection cabin 4 and the third reinforcing ribs 41. The latter intersect to form a diamond-shaped gap and is filled with non-Newtonian fluid to form a "fluid buffer layer"; the hardware intelligent module 2 is inserted into the hardware protection cabin 4 from the side and is quickly positioned and installed by using the magnetic attraction structure or buckle inside the cabin. The combination of the third reinforcing rib 41 and the fluid can alleviate most of the vibration transmission and ensure that the hardware intelligent module 2 is not damaged.

[0024] As Figure 2 、 Figure 3As shown, at least one fixing groove 14 is provided on the supporting foot columns 12 at the four corners, at least one fixing pin 33 is provided on the anti-collision module 3, a jack 34 is provided on the fixing pin 33, and a bolt 5 is provided in the jack 34. By providing the fixing groove 14 on the supporting foot columns 12 at the four corners of the tray, a plug-in connection structure is formed with the fixing pin 33 of the anti-collision module 3, and the bolt 5 is inserted into the jack 34 of the fixing pin 33 to achieve mechanical locking. During use, the fixing pin 33 on the anti-collision module 3 is inserted into the fixing groove 14 of the tray body 1, and then the bolt 5 is inserted into the jack 34 on the fixing pin 33. Compared with the snap-fastening structure, the anti-vibration and loosening resistance ability is improved, and at the same time, the modular structure is also convenient for maintenance and quick disassembly and assembly.

[0025] As Figure 3 , Figure 8 shown, a metal rod 51 is provided inside the bolt 5. The metal rod 51 inside the bolt 5 provides structural strength to ensure rigid support during locking, and to prevent deformation and failure of non-metallic materials such as plastics due to long-term impact; the head of the bolt 5 is a conical plug 52, and the design of the conical plug 52 facilitates the quick alignment and insertion of the bolt 5 into the jacks of the fixing pin 33 and the supporting foot column 12, reduces the installation resistance, and improves the operation convenience; the tail of the bolt 5 is a limiting protrusion 53, and the tail limiting protrusion 53 catches the end face of the fixing pin 33 after the bolt 5 is fully inserted to form mechanical limitation, preventing the bolt 5 from withdrawing by itself due to vibration or impact, and ensuring the reliability of the connection of the anti-collision module 3.

[0026] As Figure 4 shown, the second reinforcing ribs 32 intersect with each other to form a hexagonal honeycomb structure. The hexagonal geometric configuration can evenly disperse the impact force, and use the principle of triangular stability to conduct the external force to the tray body 1 through the reinforcing ribs. Compared with the ordinary grid structure, the stress concentration phenomenon is reduced, and the overall anti-impact performance is improved; micropores 35 are provided on the reinforcing ribs 32 at the bottom of the hexagon. The honeycomb-shaped second reinforcing ribs 32 are connected through the first micropores 35. The gaps between the second reinforcing ribs 32 and the mutually connected first micropores 35 can, on the one hand, reduce the weight of the anti-collision module 3, reduce the material cost and transportation energy consumption, and on the other hand, provide a flow channel for the non-Newtonian fluid, enabling the fluid to flow quickly and be evenly distributed among the honeycomb cells when being impacted, enhancing the response speed and action range of the shear thickening effect, and improving the anti-impact ability.

[0027] As Figure 4As shown in the figure, above the anti-collision module 3, there is a liquid inlet 36 for filling non-Newtonian fluid, and a plug 37 matching the liquid inlet 36 is provided in the liquid inlet 36. The liquid inlet 36 and the plug 37 form a non-Newtonian fluid filling and sealing structure, preventing fluid leakage and intrusion of external impurities, and ensuring the anti-collision and buffering performance of the tray during long-term use.

[0028] Furthermore, on the protective cavity 13 inside the support leg column 12, there are the same liquid inlet 36 and plug 37 as those on the anti-collision module 3, which are used to fill non-Newtonian fluid into the protective cavity 13, and buffer with the non-Newtonian fluid to avoid damage to the hardware intelligent module 2 caused by accidental collision.

[0029] As Figure 5 , Figure 6 , Figure 7 shown, the third reinforcing ribs 41 intersect with each other to form a diamond structure, and second micropores 42 are provided on the diamond-structured third reinforcing ribs 41. The diamond structure decomposes the external vibration and impact force into component forces in multiple directions through an oblique force transmission path. Compared with linear reinforcing ribs, it can effectively reduce the stress intensity of the hardware protection cabin 4. The setting of the second micropores 42 enables the non-Newtonian fluid to flow freely in the gaps between the reinforcing ribs, forming a three-dimensional buffer layer. When the tray is impacted, the fluid quickly responds through the micropores 42 and fills the stress concentration area, enhancing the local buffering performance and ensuring the stable operation of the hardware intelligent module 2 inside the hardware protection cabin 4.

[0030] As Figure 7 shown, at the outlet of the hardware protection cabin 4, there is a groove 43, a magnetic attraction component 44 is provided in the groove 43, and a buffer pad 45 is provided inside the hardware protection cabin 4. The magnetic attraction component 44 enables the hardware intelligent module 2 to be automatically adsorbed and aligned when inserted, realizing blind plug-in and fast installation. The buffer pad 45 is made of high-elastic EVA or silica gel material, forming a "rigid-flexible combination" dual protection structure with the non-Newtonian fluid. When impacted, the buffer pad 45 first absorbs high-frequency and minute vibrations, and then the non-Newtonian fluid responds to large-energy impacts.

[0031] Furthermore, there are also convex ribs at the outlet of the hardware protection cabin 4. Through the mutual cooperation of the convex ribs and the magnetic attraction component 44, the stability of the hardware intelligent module 2 is further improved.

[0032] The non-Newtonian fluid is a shear-thickening non-Newtonian fluid, and its preparation steps are as follows: Add 400 g of polyethylene glycol and 100 g of silicone oil to a three-necked flask, stir at 150 rpm for 20 min at 60 °C to fully mix the two; then add 80 g of glycerol to the mixed solution, keep at 60 °C, and stir at 200 rpm for 15 min to uniformly disperse it in the system; After mixing 10 g of silane coupling agent KH-570 with 20 g of absolute ethanol, slowly drop it into the system and react at 70 °C for 60 min, while maintaining a stirring speed of 180 rpm during this period to hydrolyze the silane coupling agent and react with the components in the system; Slowly add 200 g of nano-silica in 3 portions, with an interval of 5 min each time, and at the same time turn on the high-shear emulsifier and disperse at a speed of 3000 rpm for 40 min until there is no obvious particle agglomeration in the system; Add 2 g of antioxidant 1010, stir at 150 rpm at 60 °C for 10 min to uniformly distribute it in the system; After the reaction is completed, transfer it to a vacuum degassing machine and treat it at a vacuum degree of -0.09 MPa for 15 min, and cool the system to room temperature to obtain a shear-thickening non-Newtonian fluid.

[0033] Furthermore, in addition to the above raw materials, 4%-6% of ethylene glycol or 1.5%-2.0% of Tween-80 can also be selectively added. Among them, adding ethylene glycol additionally can enhance the wetting ability of glycerol to nano-silica, reduce agglomeration, and further reduce the risk of low-temperature viscosity mutation of the non-Newtonian fluid; As a non-ionic surfactant, Tween-80 can effectively reduce the interfacial tension of the fluid, promote the uniform dispersion of the multiphase system, prevent the sedimentation and stratification of nano-silica, ensure the long-term homogeneity of the fluid, and avoid the phenomenon of "caking" or "phase separation" of the non-Newtonian fluid.

[0034] The above are only the preferred examples of the present application and are not used to limit the present application. For those skilled in the art, the present application can have other optimization schemes and additional functions. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
