Description

Technical Field

[0001] This utility model relates to a novel battery pack tray packaging structure, and belongs to the field of new energy battery tray packaging technology. Background Technology

[0002] Existing battery pack tray packaging methods involve stacking layers together. The first method uses standard square or irregularly shaped pads to separate each layer of battery pack trays. There is no contact or limiting device between the pads. During transportation and handling, bumps can cause the pads to shift or slip, indirectly leading to collisions, squeezing, or tipping of the battery pack trays, causing damage and rendering them unusable. The second method involves contact and limiting between the pads. The pads are T-shaped, with the protruding parts used to block the battery pack trays and bear the weight of the upper trays. This method prevents the pads from shifting or slipping. The T-shaped pads are stacked together with their tails mutually limiting each other. However, in this packaging method, the weight load on the tails of the pads gradually increases from top to bottom, easily causing damage to the lower pads, indirectly leading to damage and rendering the battery pack trays unusable. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of battery pack tray packaging structure that effectively avoids damage to the pads, improves the service life of the pads, and has high packaging stability.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] A novel battery pack tray packaging structure includes a tray base and multiple split-type packaging pads. Multiple battery pack trays are stacked on the tray base, and the same number of split-type packaging pads are provided between each layer of battery pack trays, with corresponding vertical positions. Each split-type packaging pad includes a movable block and a support seat. The movable block is movably connected to the support seat and can slide freely up and down relative to the support seat. The movable block is placed between the upper and lower layers of battery pack trays, and the support seat is located at the side edge of the battery pack tray and is used for side limiting of the battery pack tray. The support seats between two adjacent split-type packaging pads are stacked together and are on the same vertical line.

[0006] Preferably, the support base of the split packaging pad is hollow inside and its rear side plate is provided with a strip hole for the movable block to pass through and slide up and down.

[0007] Preferably, the movable block is configured as a T-shaped block structure, with its head located in the internal cavity of the support base and its tail extending out of the strip hole in the side wall and placed between the battery pack trays on both sides.

[0008] Preferably, the movable block is a solid block structure.

[0009] Preferably, one side of the internal cavity of the support base is an open structure, and the open structure corresponds to the other side plate with a strip hole.

[0010] Preferably, a limiting pin is fixed in the middle of the upper side plate of the support base, and a limiting hole corresponding to the position of the limiting pin is provided in the middle of the lower side plate of the support base. When two adjacent support bases are stacked together, the limiting pin of the lower support base extends into the limiting hole of the upper support base, thereby limiting and fixing the two support bases vertically.

[0011] Preferably, a vertical limiting post is fixed in the cavity at the limiting hole position of the support base. The bottom of the limiting post has a through hole that fits with the limiting pin. The bottom of the limiting post is fixed on the limiting hole and the through hole at its bottom is coaxial with the limiting hole.

[0012] Preferably, the tray base has multiple rails in the middle, with the bottom battery pack tray placed on the rails.

[0013] Compared with the prior art, the advantages of this utility model are: the novel battery pack tray packaging structure effectively reduces the load on the tail limiting structure by designing a split pad structure, thereby avoiding damage to the pad, indirectly improving the cycle life of the pad and the stability of the packaging, greatly reducing damage to the battery pack tray during transportation, and reducing packaging costs.

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] like Figures 1 to 4 The diagram illustrates a novel battery pack tray packaging structure, primarily used for packaging battery pack trays 1 to facilitate their transportation. It includes a tray base 2 and multiple separate packaging pads. Multiple battery pack trays 1 are stacked on the tray base 2, with the same number of separate packaging pads between each layer of trays 1, their vertical positions corresponding. In this embodiment, between every two layers of battery pack trays, three separate packaging pads are arranged at intervals on the front and back sides of each battery pack tray 1, with the pads on both sides corresponding to each other. Therefore, when multiple battery pack trays are stacked together, the vertical positions of the pads in each layer also correspond, facilitating the placement of the bottom pad. The tray base has multiple guide rails 3 in the middle, with the bottom battery pack tray placed on the guide rails, creating a gap between the edge of the bottom battery pack tray and the side of the tray base for placing the pads, facilitating quick installation and placement of the pads.

[0021] Each modular packaging pad includes a movable block 4 and a support base 5. The movable block 4 is movably connected to the support base 5 and can slide freely up and down relative to the support base. The movable block 4 is placed between two battery pack trays 1. The support base 5 is located at the side edge of the battery pack tray 1 and is used for side positioning of the battery pack tray. The support bases of two adjacent modular packaging pads are stacked together and are on the same vertical line. This separates each layer of battery pack trays. Because the movable block can slide up and down, it can effectively maintain the support barrier while reducing the load on the movable block 4 of the lower pad, avoiding damage due to excessive pressure. To further improve the load-bearing effect, the movable block 4 is a solid block structure.

[0022] In this embodiment, to further facilitate the installation of the movable block 4 and its free vertical sliding, the support base 5 of the split packaging pad is hollow inside, and its rear side plate is provided with a strip-shaped hole for the movable block to pass through and slide up and down. The strip-shaped hole is set in the vertical direction, thus facilitating the movable block to slide up and down within the strip-shaped hole. When the upper battery pack tray 1 presses down on the movable block, the movable block 4 can slide down and maintain the optimal pressure-bearing position, avoiding damage due to excessive pressure over a long period of time. To further improve structural stability and prevent the movable block from sliding out of the strip-shaped hole, the movable block is set as a T-shaped block structure. Its head is located in the internal cavity of the support base, and its tail extends out of the strip-shaped hole on the side wall and is placed between the two battery pack trays 1 on both sides. Therefore, the width of the extended side of its head is greater than the width of the strip-shaped hole, thereby effectively preventing the head of the movable block from sliding out of the strip-shaped hole and maintaining the stability of the movable block during vertical sliding. In addition, to facilitate the observation of the sliding status of the movable block, one side of the internal cavity of the support base is an open structure, and the open structure corresponds to the other side plate with the strip-shaped hole.

[0023] In this embodiment, to facilitate the quick installation and positioning of the upper and lower pads, a limiting pin 6 is fixed in the middle of the upper side plate of the support base 5, and a limiting hole 7 corresponding to the position of the limiting pin is provided in the middle of the lower side plate of the support base. When two adjacent support bases 5 are stacked together, the limiting pin 6 of the lower support base 5 extends into the limiting hole 7 of the upper support base 5, thereby fixing the two support bases in a vertically limited position. Furthermore, to improve the positioning stability, a vertical limiting post 8 placed in the cavity is fixed at the position of the limiting hole of the support base 5. The bottom of the limiting post 8 has a through hole that fits with the limiting pin. The bottom of the limiting post 8 is fixed on the limiting hole, and its bottom through hole is coaxial with the limiting hole 7. When two adjacent support bases 5 are stacked together, the limiting pin 6 of the lower support base 5 extends into the limiting hole 7 of the upper support base 5 and the through hole of the corresponding limiting post 8, thereby improving the positioning stability.

[0024] In the actual packaging process, the pallet base 2 is placed at the bottom. Then, a corresponding number of separate pads are placed on the front and rear side edge plates of the pallet base 2. Next, the bottom battery pack pallet 1 is placed on the pallet base's guide rail 3, with its side edge plates resting on the movable blocks of the bottom separate pads. The height of the guide rail 3 in the pallet base 2 is set according to actual needs, ensuring that when the bottom battery pack pallet is placed on it, the side edge plates of the pallet contact the movable blocks of the side pads without gaps, so that the edges remain flat when the pallet is under pressure. Without bending, according to the aforementioned placement method of the split pads, place the second layer of split pads in the corresponding positions. Insert the limiting pin 6 on the support seat 5 of the bottom split pad into the limiting hole 7 of the support seat 5 of the second layer of split pads. After all the pads in the layer are placed and positioned, place the second layer of battery pack tray, with its edge plate placed on the movable block of the split pad. Similarly, place the upper multi-layer pads and battery pack tray in sequence until they are stacked to the specified height and quantity to complete the battery pack tray packaging process.

[0025] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
