Description

Technical Field

[0002] Pallets are the medium that transforms static goods into dynamic goods; they are a cargo-carrying platform, and moreover, a movable platform, or a mobile ground. Even goods that lose their flexibility when placed on the ground immediately gain mobility and become flexible, flowing goods once loaded onto a pallet, because goods on a pallet are always in a ready-to-move state.

[0017] The present invention has the following beneficial effects:

[0018] 1. This extendable tray mechanism, through the cooperation of the storage tray and the side frame, transforms the downward pressure received into a lateral thrust through the downward pressure crossbar and the limiting crossbar, which acts on the extension plate, giving the extension plate an outward extending thrust to the four sides of the base plate. This greatly increases the usable area of ​​the device, as well as its load-bearing capacity and storage space. Furthermore, the folding guard plate is also subjected to the thrust of the extension plate. The right-angle base transforms the lateral thrust into an oblique thrust, which acts on the folding guard plate, causing it to fold upwards. The plate forms a vertical position and provides protection on all sides. When the pushing stroke of the folding guard plate reaches its limit, the lower surface of the folding guard plate is completely in contact with the inner side of the right-angle base, forming a pressing state. This ensures that the extension plate always provides thrust to the folding guard plate, maintaining its vertical position, protecting the sides of the material, and limiting its movement. It also ensures that the material can be clamped and limited during packaging. Through the above structure, the material's own gravity is converted into the extension power of the device, which can be achieved without an additional power source.

[0019] 2. This extendable pallet mechanism, through its internal structure, further enhances the device's ability to handle special environments and materials. For example, some chemical materials cannot be touched manually; they can be placed directly on top of the device. The weight recorded by the weighing sensor is used to calculate the quantity of material, indicating how many times the recorded weight is being used. This significantly changes conventional material counting methods and allows for information transmission with an external control platform, enabling real-time monitoring of material weight and quantity changes. Furthermore, the device's counting method effectively avoids contact between operators and materials, preventing harm from chemical materials, achieving contactless weight counting, and increasing safety during manual operation.

[0020] 3. In this extendable pallet mechanism, when one end of the pallet base frame is raised or lowered, the base plate remains horizontal. This ensures that the outer side of the center of gravity traction box is closer to the lower end of the tilted pallet base frame, while the other end remains farther away. The movable rod on the closer end is compressed, and the oil inside is sent through a connecting pipe to the interior of the movable push rod on the other side. This raises the push rod and, in conjunction with the internal structure of the tilting frame, provides auxiliary support to the tilted base plate using hydraulic pressure. This hydraulic pressure provides a cushioning effect during tilting, reducing the impact on the base plate. The swaying during the flipping significantly increases the stability of the base plate when it rotates, making the device suitable for supporting special liquid materials. Through the cooperation of the flipping frame and the flipping buffer frame, the device can change the retraction distance of the movable rod according to the ground tilt angle. The retraction size is adjusted by the oil, and the corresponding size extension is achieved through the connecting pipe and the movable top rod on the other side. The movable top rod then provides support and buffering effect for the base plate, ensuring that the base plate reduces its swaying amplitude while adjusting to a level state and flipping, adapting to the support environment of liquid materials.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1

[0031] Please see Figures 1-7 One type of extendable tray mechanism includes a tray frame 1 and a storage tray 2 on the tray frame 1. The tray frame 1 includes a tray base 11, a load cell 12, feet 13, a battery box 14, a lithium battery 15, a PCB circuit board 16, a WIFI communication module 17, support feet 18, and an MCU chip 19. The tray base 11 has a cubic structure. Load cells 12 are installed on all six feet of the tray base 11. Feet 13 are also installed on the lower surface of the tray base 11. Support feet 18 are installed between two load cells 12. Feet 13 are installed at the lower ends of both the load cells 12 and the support feet 18.

[0032] A battery box 14 is provided on one side of the pallet base 11. A lithium battery 15 is snapped into the inside of the battery box 14. A PCB circuit board 16 is also installed on one side of the battery box 14. An MCU chip 19 is installed on one side of the PCB circuit board 16. A WIFI communication module 17 is installed on one side of the MCU chip 19. Both the PCB circuit board 16 and the WIFI communication module 17 are electrically connected to the lithium battery 15. The PCB circuit board 16 is electrically connected to the weighing sensor 12.

[0033] The load cell 12 is model YZC-32C, and the device has a maximum load capacity of 2 tons. The PCB circuit board 16 is model CEM-3. During use, the PCB circuit board 16 has good flatness and thickness accuracy. The MCU chip 19 is model GD32F47, which is more than 12 times faster than the traditional 8051. There are 43 interrupt sources for the horizontal connecting axis, with 4 interrupt priority levels. 64K bytes of FLASH space are used to store user code and support user configuration. The WIFI communication module 17 is model ESP-load cell 12, with a PCB antenna for external data transmission.

[0034] Before use, the material is placed on the upper part of the pallet base 11. The weight of the material is collected by the weighing sensor 12 and transmitted to the internal MCU chip 19. The weight of each material is recorded, and the weight recorded at one time is one unit. Using the information received by the MCU chip 19, when the weight of the weighing sensor 12 changes, the weight of the material at one time is calculated by how many times, so as to obtain the quantity of material in the device. This information is recorded in the internal MCU chip 19 and transmitted to the external control platform through the WIFI communication module 17.

[0035] Through the internal structure of the device, it can further meet the needs of use in special environments and with special materials. For example, some chemical materials cannot be touched by humans and can be placed directly on top of the device. The weight recorded by the weighing sensor 12 is used to calculate the quantity of the material, which is a multiple of the recorded weight. This greatly changes the conventional material counting method and enables information transmission with an external control platform to monitor changes in material weight and quantity in real time. At the same time, the counting method of the device can effectively avoid contact between operators and materials, avoid harm to personnel from chemical materials, achieve a contactless weight counting method, and increase the safety performance of the device.

[0036] Example 2

[0037] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-7 A storage tray 2 is installed above the pallet base frame 11. The storage tray 2 includes a base plate 21, a storage tray 22 and an extension plate 23. The storage tray 22 is provided at the upper end of the base plate 21. Four extension plates 23 are arranged in a ring on the upper surface of the base plate 21. The extension plates 23 are used to slide inside the base plate 21 and the storage tray 22. The extension plates 23 are used to increase the usable area of ​​the storage tray 22.

[0038] The storage tray 2 also includes a limiting crossbar 24, a pressing crossbar 25, a pressing plate 26, a limiting shaft 27, and a slide rail 28. A slide rail 28 is installed between every two extension plates 23. The upper surface of the slide rail 28 is slidably connected to the limiting crossbar 24. The two ends of the limiting crossbar 24 are slidably installed inside the extension plate 23. A pressing crossbar 25 is rotatably connected to one side of the limiting crossbar 24. The pressing plate 26 is rotatably connected to the top of the pressing crossbar 25. A storage platform 29 is provided in the middle of the base plate 21.

[0039] The storage tray 22 and the receiving platform 29 are integrated into one structure. A limiting shaft 27 is provided on one side of the receiving platform 29. The limiting shaft 27 is used to insert into the inside of the extension plate 23 and to limit the movement trajectory of the extension plate 23. The pressure plate 26 is used to contact the material and use the weight of the material to provide extension power for the extension plate 23.

[0040] One end of the extension plate 23 is connected to the side frame 3. The side frame 3 includes a folding guard plate 31, a movable bottom groove 32, a right-angle base 33, and a second inclined surface 35. The lower surface of the folding guard plate 31 is provided with the movable bottom groove 32. The four end faces of the bottom plate 21 are all provided with right-angle bases 33. The right-angle bases 33 are used to be set inside the movable bottom groove 32. One end of the inner wall of the movable bottom groove 32 is provided with a second inclined surface 35. The second inclined surface 35 is used to drive the folding guard plate 31 to fold when it contacts the right-angle base 33.

[0041] The side frame 3 also includes a first inclined surface 34 and a support shaft 36. The first inclined surface 34 is provided on one side of the upper end of the right-angle base 33. The first inclined surface 34 is used to fit with the lower surface of the second inclined surface 35. The support shaft 36 is installed at one end of the folding guard plate 31. The folding guard plate 31 and the extension plate 23 are rotatably connected by the support shaft 36. The folding guard plate 31 is interfered with by the right-angle base 33 and flips up at a vertical angle so that the bottom surface of the folding guard plate 31 fits with the inner side of the right-angle base 33.

[0042] The device's flexible counting method can handle most usage environments, but its placement area is relatively limited. In addition, the lack of a limiting structure in the upper area of ​​the device makes it prone to falling and shaking during transportation.

[0043] The extension trajectory of the storage tray 2: In use, materials are stacked on the upper surface of the storage tray 22. When placed, the materials will first come into contact with the lower pressure plate 26. After being subjected to gravity, the lower pressure plate 26 will automatically fall and embed itself into the storage platform 29. At the same time, four lower pressure crossbars 25 are connected to the lower pressure plate 26. The falling gravity of the lower pressure plate 26 is transmitted to the interior of the limiting crossbar 24 through the lower pressure crossbars 25, and the limiting crossbar 24 slides outward. During the sliding process, the four extension plates 23 are pushed outward together. After the extension plates 23 extend outward, the placement area of ​​the device is further increased, and the load-bearing capacity of the device is increased.

[0044] The movement trajectory of the folding guard plate 31: The extension plate 23 extends outward and pushes the folding guard plate 31 outward. At the same time, the interior of the movable bottom groove 32 is interfered with by the right-angle base 33, so that the upper surface of the first inclined surface 34 will be in contact with the lower surface of the second inclined surface 35. Through the inclined state of the two, the extension plate 23 continuously provides thrust, and the right-angle base 33 limits the movement, so that the lateral thrust of the extension plate 23 is transformed into an oblique thrust, thereby causing the folding guard plate 31 to flip up. At this time, the angle between the folding guard plate 31 and one end of the extension plate 23 is 90 degrees, and the lower surface of the folding guard plate 31 is in contact with the inner wall of the right-angle base 33, and the folding guard plate 31 is held in place.

[0045] This device utilizes the weight of the falling material itself to convert it into a lateral thrust, which acts on the inside of the extension plate 23 and the folding guard plate 31. This allows the extension plate 23 to extend outward, and the extension length is consistent with the length of the right-angle base 33 itself, thereby increasing the usable area of ​​the device and greatly improving its load-bearing capacity. It also drives the folding guard plate 31 to flip vertically and protects the side of the base plate 21 in real time to prevent the material from shaking and falling. Furthermore, the protective effect of the folding guard plate 31 can also provide a clamping effect when the device is being packaged.

[0046] By cooperating with the storage tray 2 and the side frame 3, the downward pressure on the lower pressure plate 26 is transformed into a lateral thrust through the lower pressure crossbar 25 and the limiting crossbar 24, and this thrust acts on the extension plate 23, giving the extension plate 23 an outward extending thrust to the four sides of the base plate 21. This greatly increases the usable area of ​​the device, as well as its load-bearing capacity and storage space. The folding guard plate 31 is also subjected to the thrust of the extension plate 23. The right-angle base 33 transforms this lateral thrust into an oblique thrust, which acts on the folding guard plate 31, causing it to fold upwards. The folding guard plate 31 is in a vertical position and provides protection on all sides. When the pushing stroke of the folding guard plate 31 reaches its limit, the lower surface of the folding guard plate 31 is completely in contact with the inner side of the right-angle base 33, forming a pressing state. This ensures that the extension plate 23 always provides thrust to the folding guard plate 31, maintaining the vertical position of the folding guard plate 31, protecting the side of the material and achieving a limit. At the same time, it can also ensure that the material can be clamped and limited during packaging. Through the above structure, the weight of the material itself is converted into the extension power of the device, without the need for an additional power source.

[0047] Example 3

[0048] This embodiment is an improvement upon embodiment 2. For details, please refer to [link / reference]. Figures 1-7The pallet frame 1 is equipped with a flipping frame 4 inside. The flipping frame 4 provides support between the pallet frame 1 and the storage tray 2, and also has an angle movement function. The flipping frame 4 includes a horizontal flip plate 41, a vertical flip plate 42, a horizontal connecting shaft 43 and a vertical connecting shaft 44. The horizontal flip plate 41 is equipped with a vertical flip plate 42 inside. The horizontal connecting shaft 43 is symmetrically installed on both sides of the horizontal flip plate 41. The horizontal connecting shaft 43 is used to ensure the horizontal rotational connection between the horizontal flip plate 41 and the pallet base frame 11. The vertical connecting shaft 44 is symmetrically installed on both sides of the inner wall of the horizontal flip plate 41. The vertical connecting shaft 44 is used to ensure the vertical movement angle between the horizontal flip plate 41 and the vertical flip plate 42.

[0049] A flip buffer frame 5 is installed on the lower surface of the base plate 21. The flip buffer frame 5 includes a fixed top plate 51 and a center of gravity traction box 52. The fixed top plate 51 is installed on the lower surface of the base plate 21. The center of gravity traction box 52 is installed at the lower end of the fixed top plate 51. The fixed top plate 51 is used to sit on the upper surface of the vertical flip plate 42.

[0050] The flip buffer frame 5 also includes a limiting outer ring frame 53, a movable rod 54, a connecting pipe 55, and a movable top rod 56. The limiting outer ring frame 53 is installed on the outside of the center of gravity traction box 52. Movable rods 54 are installed on the four end faces of the inner side of the limiting outer ring frame 53. The movable rods 54 are used to connect the inner wall of the limiting outer ring frame 53 with the outer surface of the center of gravity traction box 52. Movable top rods 56 are installed on the four end corners of the upper surface of the tray base frame 11. The lower end of the movable rod 54 is installed with a connecting pipe 55. The movable top rod 56 is connected to the movable rod 54 through the connecting pipe 55. The connecting pipe 55 and the movable top rod 56 are arranged in a square structure. Each movable rod 54 is connected to the inclined movable top rod 56. The inside of the movable rod 54 is filled with oil.

[0051] A fixed cover 59 is installed on the lower surface of the center of gravity traction box 52. Both ends of the movable rod 54 are provided with ball pins 510. The two ends of the movable rod 54 are movably connected to the inner wall of the limiting outer ring frame 53 and the outer surface of the center of gravity traction box 52 through the ball pins 510.

[0052] The limiting outer ring frame 53 is provided with side fixing frames 58 on both sides. The side fixing frames 58 are used to install the limiting outer ring frame 53 on the inner side of the pallet base frame 11. The four corners of the lower surface of the base plate 21 are provided with top sleeves 57. The top of the movable top rod 56 is used to insert into the inside of the top sleeve 57.

[0053] The storage of materials in the equipment should not be limited to the area and protection function. In normal use, some special liquid materials require extreme placement requirements. The placement environment needs to be close to or equal to a horizontal state. The slope and flatness of the ground have a significant impact on the placement environment of the equipment.

[0054] The movement trajectory of the flipping frame 4: the horizontal flip plate 41 and the pallet base frame 11 have a horizontal flipping angle, and the horizontal flip plate 41 and the vertical flip plate 42 have a vertical flipping angle. The combination of the two has multiple angle adjustment functions, and provides support between the pallet frame 1 and the storage tray 2 while also having an angle adjustment function.

[0055] The center of gravity traction box 52 and the base plate 21 are placed vertically. Through the gravity of the center of gravity traction box 52, the center of gravity of the base plate 21 is downward, so that the base plate 21 is always in a horizontal and vertical state. When used in combination with the flipping frame 4, the base plate 21 can be kept horizontal when the pallet structure 1 is placed, regardless of the inclination of the ground. This further increases the activity effect of the device and the stability when bearing load, and avoids safety hazards caused by material leakage.

[0056] according to Figure 6 As shown, the addition of the flipping buffer frame 5 further improves the stability between the pallet frame 1 and the storage tray 2. When the pallet base frame 11 tilts to one end, the other end will rise relatively. When it rises, the base plate 21 remains horizontal, making the outer side of the center of gravity traction box 52 closer to the shorter side of the tilted pallet base frame 11, while the other end is farther away. The movable rod 54 on the closer side will be compressed, and the oil inside it will be sent to the interior of the movable push rod 56 on the other side through the connecting pipe 55, causing the movable push rod 56 to rise and cooperate with the internal structure of the flipping frame 4. Using hydraulic pressure, it provides auxiliary support for the tilted base plate 21, so that the base plate 21 can be flipped smoothly. Through the action of hydraulic pressure, a buffering effect is achieved, reducing the shaking of the base plate 21 when it is flipped, and significantly increasing the stability of the base plate 21 when it is rotated. This makes the device suitable for supporting special liquid materials. Through the cooperation of the flipping frame 4 and the flipping buffer frame 5, the device can change the retraction distance of the movable rod 54 according to the ground tilt angle. The size of the retraction is adjusted by the hydraulic fluid, and the corresponding size extension is achieved through the connecting pipe 55 and the movable top rod 56 on the other side. The movable top rod 56 then provides support and buffering effect for the base plate 21, ensuring that the base plate 21 reduces its shaking amplitude while adjusting to a horizontal state and flipping, adapting to the support environment of liquid materials.
