Description

Technical Field

[0001] This utility model relates to the field of new energy battery pack production technology, and in particular to a battery pack transfer tray. Background Technology

[0002] With the release of national policies related to new energy vehicles, the production of new energy vehicles has shown a rapid increasing trend, and pure electric vehicles, as a model of new energy vehicles, have attracted much attention. However, the battery pack, as one of the most important components of a pure electric vehicle, often requires transfer operations during its production process. The battery pack of a pure electric vehicle is large in size and heavy in weight, and different transfer methods are required in different transfer environments. Therefore, the transfer of battery packs is a major problem that needs to be solved in this field.

[0003] For example, utility model patent application number 202420958983.9 specifically discloses a carrying tray for battery pack transportation, including a base, a first support assembly, and two second support assemblies. The first support assembly includes two first support members, which are spaced apart from each other and connected to the base, forming two first support surfaces. The two second support assemblies are respectively disposed on both sides of the two first support members and are detachably connected to the base. The second support assembly includes multiple second support members, which can be stacked sequentially in the vertical direction to form second support surfaces of different heights. This utility model can solve the problem that the fixed height of the support platforms on both sides of the tray cannot be adaptively adjusted according to specific usage conditions, resulting in the inconvenience of using the carrying tray.

[0004] Although the aforementioned patent solution discloses a carrier pallet for transporting battery packs, the carrier pallet structure is too complex when transporting battery packs, and the carrier pallet cannot be smoothly picked up by a forklift, and there is no protection on the top of the battery pack.

[0005] Therefore, there is an urgent need to develop a simple carrying tray that is easy to forklift and also provides protection for the top of the battery pack. Utility Model Content

[0006] To address the above problems, this utility model provides a battery pack transfer tray, which utilizes the combination of limiting posts and binding straps to form a structure on the tray for quick and easy fixation and support of the battery pack. The structure is simple.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A battery pack transfer tray, comprising:

[0009] Tray, limit posts, and binding straps;

[0010] The tray is positioned horizontally and carries a horizontally placed battery pack.

[0011] The limiting posts are respectively disposed at the four corners of the tray, and the limiting posts and the tray together form a support area for placing the battery pack;

[0012] The two ends of the binding strap are detachably connected to the tray, and the binding strap binds and secures the battery pack on the tray.

[0013] As an improvement, the tray includes a tray portion and supporting legs;

[0014] The disk is square in shape, and the limiting posts are vertically installed at the four corners of the disk.

[0015] The support leg is disposed on the lower end surface of the disc, and three sets of the support leg are equidistantly arranged along the width direction of the disc, with a forklift hole groove formed between two adjacent sets of the support leg.

[0016] As an improvement, the upper surface of the disc is provided with a shock-absorbing pad and a shock-absorbing rubber strip to reduce the vibration of the battery pack.

[0017] As an improvement, the support leg includes a mounting column and a support plate;

[0018] The mounting posts are arranged in three sets at equal intervals along the length of the disc, and an auxiliary forklift slot is formed between adjacent mounting posts. The auxiliary forklift slot is perpendicular to the forklift hole slot.

[0019] The support plate is trapezoidal in shape and is connected to the mounting column.

[0020] As an improvement, the limiting post includes a column and a connecting angle iron;

[0021] The column is a hollow square tube, and the column is connected to the plate by connecting angle iron.

[0022] The cross-section of the connecting angle iron is U-shaped, and a waist-shaped hole is provided on the connecting angle iron. A through hole corresponding to the waist-shaped hole is provided on the column.

[0023] As an improvement, a trapezoidal positioning groove is provided on the upper edge of the connecting angle iron, and a trapezoidal positioning block is provided on the column to correspond to and cooperate with the trapezoidal positioning groove.

[0024] As an improvement, a positioning post is provided below the tray to cooperate with the column. The positioning post is inserted into the slot at the top of the column, so that the two sets of transfer trays are stacked.

[0025] As an improvement, the column is provided with a crossbar assembly to limit and protect the top of the load-bearing area. The crossbar assembly includes a connecting seat, a crossbar square tube, and a connecting square tube. The connecting seat is correspondingly inserted and fitted into the slot. The connecting seat has a spherical elastic protrusion protruding outward. The side wall of the slot is provided with a positioning hole that engages with the spherical elastic protrusion. The crossbar square tube and the connecting seat are rotatably connected by a rotating bolt. The crossbar square tubes are connected to each other by the connecting square tube. The insertion parts of the crossbar square tube and the connecting square tube are connected by inserting a connecting bolt.

[0026] As an improvement, when the transfer pallet is used for transfer, the crossbar square tubes set at the diagonal are arranged in a cross configuration through connecting square tubes, and the middle position of the connecting square tubes is provided with interlocking notches.

[0027] As an improvement, the binding strap includes a binding connector and an elastic band;

[0028] Two sets of binding joints are symmetrically arranged, and the binding joints are installed on the disc by interference fit.

[0029] The elastic band is elastically stretched and is used to bind the battery pack, with both ends of the elastic band bound to the binding connector.

[0049] Example 1:

[0050] like Figure 1 As shown, a battery pack transfer tray includes:

[0051] Pallet 1, limiting post 2, and binding strap 3;

[0052] The tray 1 is horizontally positioned and carries a horizontally placed battery pack;

[0053] The limiting posts 2 are respectively disposed at the four corners of the tray 1, and the limiting posts 2 and the tray 1 are combined to form a support area 20 for placing the battery pack;

[0054] The two ends of the binding strap 3 are detachably connected to the tray 1, and the binding strap 3 binds and fixes the battery pack on the tray 1.

[0055] The tray 1 includes a tray portion 11 and supporting legs 12;

[0056] The disk 11 is square in shape, and the limiting post 2 is vertically installed at the four corners of the disk 11. The upper surface of the disk 11 is provided with a shock-absorbing pad 111 and a shock-absorbing rubber strip 112 for absorbing the shock of the battery pack.

[0057] The support leg 12 is disposed on the lower end face of the disc portion 11. Three sets of the support leg 12 are equidistantly arranged along the width direction of the disc portion 11, and a forklift hole groove 10 is formed between two adjacent sets of the support leg 12.

[0058] It should be noted that in this application, the battery pack is placed in the support area 20 formed by the four limiting posts 2, and then the battery pack is tied to the tray 1 by the binding straps 3, so that the battery pack is fixed on the tray 1. The tray 11 in the tray 1 is used to support the battery pack, and the support legs 12 support the tray 11. The limiting posts 2 are made of hollow steel pipes, and the limiting posts 2 form rigid protection for the four corners of the tray 1, protecting the battery pack from collision during transportation to avoid damage and impact.

[0059] Furthermore, by securing the battery pack with the binding straps 3, the degree of freedom of the battery pack on the tray 1 is reduced, preventing the battery pack from shaking during transportation.

[0060] Example 2:

[0061] Referring to Example 1, the difference between Example 2 and Example 1 lies in the following:

[0062] like Figure 4 and Figure 5 As shown, the support leg 12 includes a mounting column 121 and a support plate 122;

[0063] The mounting posts 121 are arranged in three sets at equal intervals along the length of the disc 11, and an auxiliary forklift slot 123 is formed between adjacent mounting posts 121. The auxiliary forklift slot 123 is arranged perpendicular to the forklift hole slot 10.

[0064] The support plate 122 is trapezoidal in shape and is connected to the mounting column 121.

[0065] It should be noted that, in order to facilitate forklift picking and transportation, the support legs 12 form longitudinal and transverse forklift slots 10 and auxiliary forklift slots 123 below the pallet 11, so that the forklift can pick up the pallet from any direction on any of the four sides of the pallet 11, and the pallet can be smoothly loaded with battery packs for transportation, which is convenient and fast.

[0066] Example 3:

[0067] Referring to Example 1, the difference between Example 3 and Example 1 lies in the following:

[0068] like Figures 2-6 As shown, the limiting post 2 includes a column 21 and a connecting angle iron 22;

[0069] The column 21 is a hollow square tube, and the column 21 is connected to the disk 11 by connecting angle iron 22;

[0070] The cross-section of the connecting angle iron 22 is U-shaped, and the connecting angle iron 22 has a waist-shaped hole 221. The column 21 has a through hole 210 that corresponds to and matches the waist-shaped hole 221.

[0071] Furthermore, a trapezoidal positioning groove 222 is provided on the upper edge of the connecting angle iron 22, and a trapezoidal positioning block 212 is provided on the column 21 to cooperate with the trapezoidal positioning groove 222.

[0072] Furthermore, a positioning post 13 is provided below the tray 11 to cooperate with the column 21. The positioning post 13 is inserted into the slot 211 on the top of the column 21, so that the two sets of transfer trays are stacked.

[0073] It should be noted that, in order to facilitate the assembly of the pallet, the limiting post 2 on the pallet adopts the method of disassembling and assembling the upright post 21 and the connecting angle iron 22. Specifically, the connecting angle iron 22 is directly connected and fixed to the pallet part 11, while the upright post 21 is connected to the connecting angle iron 22 by bolts. When assembling the upright post 21 and the connecting angle iron 22, the cooperation between the trapezoidal positioning groove 222 and the trapezoidal positioning block 212 enables the upright post 21 and the connecting angle iron 22 to be quickly assembled, making the assembly quick.

[0074] Furthermore, the interlocking of the slot 211 and the positioning post 13 allows the trays to be stacked, enabling them to be quickly and accurately stacked when not in use, preventing them from being randomly piled up and taking up unnecessary space.

[0075] Example 4:

[0076] Referring to Example 1, the difference between Example 4 and Example 1 lies in the following:

[0077] like Figures 7-10 As shown, the column 21 is provided with a crossbar assembly 4 to limit and protect the top of the support area 20. The crossbar assembly 4 includes a connecting seat 41, a crossbar square tube 42, and a connecting square tube 43. The connecting seat 41 is correspondingly inserted and fitted into the slot 211. The connecting seat 41 has a spherical elastic protrusion 411 protruding outward. The side wall of the slot 211 is provided with a positioning hole 213 that engages with the spherical elastic protrusion 411. The crossbar square tube 42 and the connecting seat 41 are rotatably connected by a rotating bolt 44. The crossbar square tubes 42 are connected to each other by the connecting square tube 43. The insertion parts of the crossbar square tube 42 and the connecting square tube 43 are connected by a connecting bolt 45.

[0078] Furthermore, when the transfer pallet is used for transfer, the diagonally positioned crossbar square tubes 42 are cross-connected by connecting square tubes 43, and interlocking notches 431 are provided at the middle position of the connecting square tubes 43.

[0079] It should be noted that, in order to protect the top of the battery pack in the carrying area 20 and prevent damage from the top during transportation, the slot 211 is used as the installation reference. The ball elastic protrusion 411 cooperates with the protrusion of the positioning hole 213 to achieve quick assembly of the connector 41 and the slot 211. The structure of the ball elastic protrusion 411 is similar to that of the glass ball screw. The protrusion can be extended and floated by pressing. The slot 211 is square, and the corresponding connector 41 is also a square column. The crossbar square tube 42 can be rotated by rotating the bolt 44, so that the crossbar group 4 forms a cross transportation state and a parallel loading and unloading state of the battery pack. This allows for quick loading and unloading of the battery pack, thus achieving protection.

[0080] Furthermore, in order to make the assembly of the crossbar assembly 4 faster, the connecting square tube 43 adopts a notch 431, so that when the connecting square tubes 43 cross, the crossbar assembly 4 can be staggered by the cooperation of the notches 431. When disassembling, only the connecting bolts 45 need to be removed to disassemble the connecting square tube 43 and the crossbar square tube 42. The assembly is also very quick.

[0081] Example 5:

[0082] Referring to Example 1, the difference between Example 5 and Example 1 lies in the following:

[0083] like Figures 6-7 As shown, the binding strap 3 includes a binding connector 31 and an elastic band 32;

[0084] Two sets of binding connectors 31 are symmetrically arranged, and the binding connectors 31 are installed on the disc portion 11 by interference fit.

[0085] The elastic band 32 is elastically stretched and is used to bind the battery pack. Both ends of the elastic band 32 are bound to the binding connector 31.

[0086] It should be noted that the binding strap 3 is relatively short and needs to be elastically stretched to fix both ends of the binding strap 3 to the disc 11. Specifically, when fixing the binding strap 3, the binding connector 31 is directly embedded into the disc 11 by interference fit, so that the binding connector 31 is fixed to the tray 1. When disassembling, you only need to pry out the binding connector 31, which is quick and convenient to install.

[0087] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
