Description

Technical Field

[0001] The present invention relates to the technical field of battery storage, and specifically provides a stacking rack platform structure and a stacking and positioning method for battery module units. Background Art

[0002] A stacking rack, also known as a Quick Rack or pallet rack, is a handling and storage device derived from pallets. It is one of the multi-functional devices for unitized cargo handling, commodity storage, and commodity circulation, and needs to be used in conjunction with a forklift. Currently, during the battery production process, the assembled battery module units need to be temporarily stored in a warehouse and then transported in batches. When storing, since the stacking rack can be stacked together according to the situation to form a three-dimensional storage mode without the need for equipment such as shelves, storage cages, and pallets, it is suitable for areas where it is not suitable to invest in shelves, such as leased warehouses, low old-fashioned warehouses, or workshop temporary storage areas. Usually, stacking racks are used to store battery module units. However, the existing stacking racks usually have only one support layer, and only one group of battery module units can be placed on one support layer. When stacking four groups of battery module units, the forklift needs to stack the stacking racks in pairs first, and then stack the two stacked stacking racks together again, which requires three operations. The operation is relatively cumbersome, and stacking multiple stacking racks together also increases the operation difficulty for forklift operators;

[0003] For example, the battery module stacking rack disclosed in a Chinese patent, with the publication number CN219340037U, has only one support layer, and forklift operators need to perform multiple operations during the stacking process. As the stacking quantity increases, the operation difficulty also increases continuously, and the operation is relatively cumbersome;

[0004] Therefore, a stacking rack platform structure and a stacking and positioning method for battery module units are proposed. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stacking rack platform structure and a stacking and positioning method for battery module units, which solve the problem that the existing stacking racks usually have only one support layer, and only one group of battery module units can be placed on one support layer. When stacking four groups of battery module units, the forklift needs to stack the stacking racks in pairs first, and then stack the two stacked stacking racks together again, which requires three operations. The operation is relatively cumbersome, and stacking multiple stacking racks together also increases the operation difficulty for forklift operators.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A stacking rack platform structure and a stacking positioning method for a battery module unit, including columns, crossbars connected to the columns, and forklift sleeves installed at the bottom of the crossbars. A pressing block for providing power to a power rod is installed inside the crossbar. One end of a first spring is installed at the bottom of the pressing block, and the other end of the first spring is installed on the crossbar. A support assembly is arranged outside the column. The support assembly includes a left support plate installed on the side wall of the column through a rotating shaft and a right support plate installed on the side wall of the column through a rotating shaft. One end of the power rod is installed with a connecting rod for transmission. One end of the connecting rod is installed with a support rod for transmission. Teeth for transmission are arranged on the side wall of the support rod. A gear for transmission is arranged outside the support rod. The gear meshes with the teeth, and the gear is installed at one end of the rotating shaft.

[0007] Preferably, the support assembly further includes a fixing plate installed inside the left support plate for locking. A limiting rod for guiding the fixing plate is installed on the side wall of the fixing plate. One end of the fixing plate is inclined. An extrusion block for providing power to the fixing plate is connected to the outer wall of the inclined fixing plate. A first sliding rod is installed on the side wall of the extrusion block.

[0008] Preferably, a guiding rod for guiding the first sliding rod is installed inside the first sliding rod. One end of the guiding rod is installed inside the left support plate. A second spring for providing elastic force to the first sliding rod is installed on the side wall of the first sliding rod.

[0009] Preferably, a threaded rod is installed inside the column. One end of the threaded rod is installed with a connecting block. One end of the connecting block is installed with a second sliding rod for applying a force to the first sliding rod. A fixing rod is installed at the bottom of the second sliding rod. One end of the fixing rod is installed with a first magnet.

[0010] Preferably, a guiding plate is installed on the side wall of the left support plate. A moving rod for providing a supporting force to a second magnet is installed on the guiding plate. One end of the moving rod is installed with a third spring for providing elastic force to the moving rod. One end of the third spring is installed on the side wall of the guiding plate.

[0011] Preferably, a steel wire for transmission is installed at one end of the moving rod. One end of the steel wire is connected to a push rod. One end of the push rod is inclined. The push rod is installed inside the fixing plate.

[0012] Preferably, a convex block for locking the left support plate is installed inside the fixing plate. A sliding block is installed on the side wall of the convex block. The side wall of the sliding block is inclined. The inclined side wall of the sliding block is adapted to the inclined end of the push rod.

[0013] Preferably, one end of the push rod is equipped with a fourth spring, and one end of the fourth spring is installed inside the fixed plate.

[0014] The present invention also provides a stacking and positioning method applicable to a stacking rack platform structure of a battery module unit, including the following steps:

[0015] S1. Place the battery module unit to be temporarily stored after combination on the cross bar, and ensure that the battery module unit can provide a downward pressure to the pressing block;

[0016] S2. Under the action of the pressure, the pressing block moves downward, and through transmission, the left support plate and the right support plate are flipped and combined together;

[0017] S3. Provide support to another group of battery module units through the combined left support plate and right support plate;

[0018] S4. Insert the fork of the forklift into the forklift sleeve to perform the stacking operation.

[0019] Preferably, the length of the right support plate is less than the length of the left support plate.

[0020] The present invention provides a stacking rack platform structure and a stacking and positioning method for a battery module unit. Compared with the prior art, the following beneficial effects are achieved:

[0021] (1). For the stacking rack platform structure and the stacking and positioning method of the battery module unit, by setting up columns, cross bars, forklift sleeves, pressing blocks, power rods, first springs, connecting rods, support rods, gears, left support plates, and right support plates, a stacking rack platform structure is formed by the cross bars, columns, and forklift sleeves to store the combined battery module units. When the battery module unit is placed on the cross bar, it will provide a downward gravity to the pressing block. Through transmission, the left support plate and the right support plate can be flipped and spliced together from the outside to the inside, thus forming a new support layer, enabling two groups of battery module units to be placed on one stacking rack platform structure. There is no need to manually flip the support plates, which makes the operation more convenient. At the same time, it can save the number of forklift stacking operations. Only by stacking once with a forklift can four battery module units be stacked and stored, saving the operation cost.

[0022] (2). For the stacking rack platform structure and the stacking and positioning method of the battery module unit, by setting up a fixed plate, a limiting rod, an extrusion block, a guide rod, a second spring, a first sliding rod, a second sliding rod, a connecting block, and a threaded rod, during the flipping process of the left support plate, the internal fixed plate will be driven to flip synchronously. During the process of the fixed plate flipping to the Figure 11 shown position, it can slide out linearly from the left support plate and finally be stuck into the right support plate, so that the left support plate and the right support plate can be combined together and remain in the Figure 11The position shown, thus providing a supporting force to the battery module unit. After the bottom battery unit module is placed, the supporting components of the upper battery unit module can be automatically combined. Only by rotating the threaded rod can the unlocking operation of the supporting components be carried out simply. While providing a stable supporting force to the battery unit module, only by stacking once with a forklift can four battery module units be stacked and stored.

[0023] (3) The stacking rack platform structure and stacking positioning method of the battery module unit. By setting the fixed rod, magnet one, magnet two, moving rod, spring three, steel wire, push rod, guide plate, spring four, sliding block, and convex block, when the fixed plate is moved out of the left support plate and clamped into the right support plate, the convex block enters the right support plate along with the fixed plate until it moves to Figure 11 the position shown. The convex block loses resistance, enabling the convex block to slide out of the fixed plate under its own gravity and be clamped into the fixing hole opened on the surface of the right support plate, thereby further fixing and locking between the left support plate and the right support plate, ensuring that a stable supporting force can be provided to the battery module unit. Only by rotating the threaded rod can the locking between the left support plate and the right support plate be released, which is simple and convenient. While providing a stable supporting force to the battery unit module, only by stacking once with a forklift can four battery module units be stacked and stored. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-12 , the present invention provides two technical solutions:

[0039] Embodiment 1: A stacking rack platform structure and a stacking and positioning method for a battery module unit, including a vertical column 1, a cross bar 11 fixedly connected to the vertical column 1, and a forklift sleeve 12 fixedly installed at the bottom of the cross bar 11. A pressing block 2 for providing power to a power rod 21 is slidably installed inside the cross bar 11. A first spring 22 for providing elastic force for resetting the pressing block 2 is fixedly installed at the bottom of the pressing block 2. One end of the first spring 22 is fixedly installed on the cross bar 11. A support assembly is arranged outside the vertical column 1. The support assembly includes a left support plate 3 movably installed on the side wall of the vertical column 1 through a rotating shaft, and a right support plate 31 movably installed on the side wall of the vertical column 1 through a rotating shaft. One end of the power rod 21 is fixedly installed with a connecting rod 23 for transmitting the power generated by the downward pressing of the pressing block 2. One end of the connecting rod 23 is fixedly installed with a support rod 24 for transmitting the power generated by the downward pressing of the pressing block 2. A row of teeth for transmitting the power generated by the downward pressing of the pressing block 2 is fixedly installed on the side wall of the support rod 24. A gear 25 for transmitting the power generated by the downward pressing of the pressing block 2 is arranged outside the support rod 24. The gear 25 meshes with the teeth. The side wall of the gear 25 is fixedly installed at one end of the rotating shaft.

[0040] During use, a stacking rack platform structure is formed by the cross bar 11, the vertical column 1, and the forklift sleeve 12 to store the combined battery module units. When the battery module units are placed on the cross bar 11, a downward gravity is provided to the pressing block 2, causing the pressing block 2 to drive the power rod 21 to move. The power rod 21 drives the connecting rod 23 to move, and the connecting rod 23 drives the support rod 24 to move. The teeth on the outer wall of the support rod 24 close to the gear 25 mesh with the gear 25, thereby driving the gear 25 to rotate. The gear 25 drives the rotating shaft to rotate, and the rotating shaft drives the left support plate 3 and the right support plate 31 to flip, so that the left support plate 3 and the right support plate 31 can be flipped and spliced together from the outside to the inside, thus forming a new support layer. This enables a stacking rack platform structure to place two groups of battery module units, eliminating the need for manual flipping of the support plates, making the operation more convenient. At the same time, the number of forklift stacking operations can be saved. Only by stacking once with a forklift can four battery module units be stacked and stored, saving operating costs.

[0041] Embodiment 2. The technical solution of this embodiment different from that of Embodiment 1 includes: The support assembly further includes a fixing plate 4 slidably installed inside the left support plate 3 for locking between the combined left support plate 3 and right support plate 31. A limiting rod 41 for guiding the fixing plate 4 is fixedly installed on the side wall of the fixing plate 4. One end of the limiting rod 41 is slidably installed inside the left support plate 3. One end of the fixing plate 4 is inclined. An extrusion block 42 for providing power to the fixing plate 4 is connected to the outer wall of the fixing plate 4 where it is inclined. The side wall of the extrusion block 42 is fixedly installed at one end of a first sliding rod 45. A guiding rod 43 for guiding the first sliding rod 45 is slidably installed inside the first sliding rod 45. One end of the guiding rod 43 is fixedly installed inside the left support plate 3. A second spring 44 for providing elastic force to the first sliding rod 45 is fixedly installed on the side wall of the first sliding rod 45. One end of the second spring 44 is fixedly installed inside the left support plate 3. A threaded rod 48 is installed inside the column 1 in a threaded manner. One end of the threaded rod 48 is movably installed on the side wall of a connection block 47 through a bearing. One end of the connection block 47 is fixedly installed with a second sliding rod 46 for applying a force to the first sliding rod 45. One end of the second sliding rod 46 is inclined. A fixing rod 5 is fixedly installed at the bottom of the second sliding rod 46. A first magnet 51 is fixedly installed at one end of the fixing rod 5. A guiding plate 57 is fixedly installed on the side wall of the left support plate 3. A moving rod 53 for providing a supporting force to a second magnet 52 is slidably installed on the guiding plate 57. One end of the moving rod 53 is fixedly connected to the side wall of the second magnet 52. The second magnet 52 and the first magnet 51 are magnetically attracted to each other. A third spring 54 for providing elastic force to the moving rod 53 is fixedly installed at one end of the moving rod 53. One end of the third spring 54 is fixedly installed on the side wall of the guiding plate 57. A steel wire 55 for transmission is fixedly installed at one end of the moving rod 53. One end of the steel wire 55 is fixedly connected to a push rod 56. One end of the push rod 56 is inclined. The push rod 56 is slidably installed inside the fixing plate 4. A convex block 510 for locking the left support plate 3 is slidably installed inside the fixing plate 4. A sliding block 59 is fixedly installed on the side wall of the convex block 510. The side wall of the sliding block 59 is inclined. The inclined side wall of the sliding block 59 and the inclined end of the push rod 59 are in sliding contact with each other. A fourth spring 58 is fixedly installed at one end of the push rod 56. One end of the fourth spring 58 is fixedly installed inside the fixing plate 4.

[0042] During use, during the flipping process of the left support plate 3, the fixing plate 4 inside it will be driven to flip synchronously. When the fixing plate 4 flips accordingly to Figure 11During the process of reaching the position shown, the first sliding rod 45 will come into contact with the second sliding rod 46. The second sliding rod 46 provides resistance to the first sliding rod 45, causing the first sliding rod 45 to slide along the guide rod 43 towards the side close to the fixed plate 4. The first sliding rod 45 drives the extrusion block 42 to move, and the extrusion block 42 pushes the fixed plate 4 to move. The fixed plate 4 is limited by the limit rod 41, so that the fixed plate 4 will slide out linearly from the left support plate 3 under the action of this thrust and finally be stuck into the right support plate 31, so that the left support plate 3 and the right support plate 31 can be combined together and remain in Figure 11 the position shown, thereby providing a supporting force for the battery module unit. While providing a stable supporting force for the battery unit module, only one forklift stacking is required to stack and store four battery module units. When it is necessary to transfer the battery module unit away, after transferring the upper battery module unit, rotate the threaded rod 48 so that the threaded rod 48 moves from Figure 3 the position shown towards the side away from the left support plate 3. The threaded rod 48 drives the connecting block 47 to move, and the connecting block 47 drives the second sliding rod 46 to move, so that the second sliding rod 46 no longer exerts a force on the first sliding rod 45. At this time, the first sliding rod 45 is reset to Figure 6 the state shown under the action of the second spring 44, thereby releasing the locking of the fixed plate 4. Then, when removing the bottom battery module unit, the left support plate 3 and the right support plate 31 can be pushed open so that they can be reset to Figure 1 the state shown. When the fixed plate 4 moves out of the left support plate 3 and is stuck into the right support plate 31, the convex block 510 enters the right support plate 31 along with the fixed plate 4 until it moves to Figure 11When in the shown position, the bump 510 loses the resistance, enabling the bump 510 to slide out of the fixed plate 4 under the action of its own gravity and snap into the fixing hole formed on the surface of the right support plate 31, thereby further fixing and locking the left support plate 3 and the right support plate 31, ensuring that a stable supporting force can be provided for the battery module unit. At the same time, the first magnet 51 and the second magnet 52 just adsorb together. When it is necessary to release the lock between the left support plate 3 and the right support plate 31, rotate the threaded rod 48 to drive the second sliding rod 46 to move. The second sliding rod 46 synchronously drives the fixed rod 5 to move. The fixed rod 5 drives the first magnet 51 to move. The first magnet 51 drives the second magnet 52 to move. The second magnet 52 drives the moving rod 53 to move. The moving rod 53 is in sliding fit with the guide plate 57, enabling the moving rod 53 to move linearly along the guide plate 57. The moving rod 53 pulls the steel wire 55 to move. The steel wire 55 drives the push rod 56 to move, causing the push rod 56 to push the sliding block 59 to move, making the sliding block 59 move away from the side where the push rod 56 is located. The sliding block 59 drives the bump 510 to move, enabling the bump 510 to retract from the fixing hole into the fixed plate 4, thereby releasing the lock between the left support plate 3 and the right support plate 31. When the left support plate 3 and the right support plate 31 are subjected to an upward acting force, the two flip outward with the rotating shaft as the axis, causing the separation between the first magnet 51 and the second magnet 52. The moving rod 53 is reset to Figure 7 the shown state and waits for the next use.

[0043] The embodiment of the present invention also provides a stacking and positioning method applicable to a stacking rack platform structure of a battery module unit, including the following steps:

[0044] S1. Place the battery module unit to be temporarily stored after combination on the cross bar 11 and ensure that the battery module unit can provide a downward pressure to the pressing block 2;

[0045] S2. The pressing block 2 moves downward under the action of the pressure, and through transmission, the left support plate 3 and the right support plate 31 flip and combine together;

[0046] S3. Provide support for another group of battery module units through the combined left support plate 3 and right support plate 31;

[0047] S4. Insert the fork of the forklift into the forklift sleeve 12 to perform the stacking operation.

[0048] Wherein the length of the right support plate 31 is less than the length of the left support plate 3, so that when the fixed plate 4 extends out of the left support plate 3, it will not be directly stuck.
