Description

Technical Field

[0001] This utility model belongs to the field of battery handling technology, and in particular relates to a battery pack turnover tray. Background Technology

[0002] In the field of lead-carbon battery energy storage, as the energy density of battery energy storage systems continues to increase, the external dimensions of the battery pack must be reduced as much as possible for the same energy. This necessitates eliminating the need for specialized forklift and hoisting structures on the bottom and outer sides of the battery pack, such as... Figure 1 The diagram shows the structure of an existing battery pack. In practical implementation, the scaled-down battery pack encounters the following problems: When the battery pack is assembled and removed from the production line, there are typically two handling methods: forklift handling and hoisting. According to handling requirements, the forklift can only insert its forks from the front (panel side) of the battery pack to lift the bottom, and the hoisting clamps can only grip the bottom from the left and right sides for lifting. Applying any lifting force to the front panel is prohibited. Furthermore, the forklift forks and hoisting clamps must be able to freely retract after the battery pack is placed on the pallet. The existing battery pack turnover pallet structure is simple and cannot achieve multi-angle insertion and handling. For example, [the following is an example, as per authorization notice number CN 221438777]. U's utility model patent discloses a battery turnover tray, which includes a base frame and a tray (to avoid confusion with the battery panel mentioned in the text, the panel in the prior art is referred to as the tray). The tray is connected to the upper end face of the base frame and is provided with limiting components for fixing and installing batteries. According to the description and drawings, when lifting, the fork can only pass between the two battery limiting components for unilateral handling, thus reducing the flexibility of handling.

[0003] Based on the above problems, this application designs a battery pack turnover tray. Utility Model Content

[0004] The purpose of this utility model is to provide a battery pack turnover tray, which has a simple structure, high flexibility of use, and solves the shortcomings of the existing background technology.

[0005] This solution provides a battery pack turnover pallet: including longitudinal support rods and transverse support rods, which are arranged in a cross pattern to form a frame-like pallet body. Multiple support blocks are provided on the contact side between the pallet body and the battery pack. The multiple support blocks are arranged at equal intervals in both the transverse and longitudinal directions, and the gap between two adjacent support blocks forms a retraction area for the battery pack handling tool to retract.

[0006] As a preferred embodiment of this application: the transverse support rod and the longitudinal support rod are arranged perpendicularly and intersecting each other, and the longitudinal support rod is located at the upper end of the transverse support rod, while the support block is fixed on the longitudinal support rod.

[0007] As a preferred embodiment of this application: the bottom of the horizontal support rod is provided with multiple foot supports, the height of which is the same as that of the support block, or the height of which is greater than the thickness of the battery pack.

[0008] As a preferred embodiment of this application: when the height of the foot support is greater than the thickness of the battery pack, the foot support is disposed on the transverse support rod located at the edge of the tray body, and the size of the tray body is larger than the battery pack. When the two tray bodies are stacked, the foot support at the bottom of the upper tray body can contact the transverse support rod at the edge of the lower tray body.

[0009] As a preferred embodiment of this application: a locking element is provided, which is a right-angle block and has a threaded hole. The locking element can be used to lock the support block and the foot support onto the longitudinal support rod and the transverse support rod, respectively.

[0010] As a preferred embodiment of this application: the upper end face of the longitudinal support rod is provided with a sliding groove, and the bottom of the support block is provided with a slider. The support block slides with the longitudinal support rod through the cooperation of the slider and the sliding groove so as to adjust the number of support blocks and the distance between two adjacent support blocks.

[0011] As a preferred embodiment of this application: both the support block and the foot support have honeycomb inner cavities, and their end faces are provided with wear-resistant layers.

[0012] As a preferred embodiment of this application: the support block is fixed on the longitudinal support rod and forms a longitudinal support unit, the foot support is fixed on the transverse support rod and forms a transverse support unit, and increasing the number of the longitudinal support units and transverse support units can expand the size of the pallet body.

[0013] As a preferred embodiment of this application: the two ends of the horizontal support unit and the vertical support unit are respectively provided with female and male connectors, and the two horizontal support units or two vertical support units in the same direction are connected end to end through the female and male connectors.

[0014] As a preferred embodiment of this application, the female connector is a pluggable inner and outer sleeve.

[0015] Compared with existing technologies, the advantages of this application are:

[0016] The battery pack turnover pallet of this solution has a frame structure composed of horizontal and vertical support rods arranged in a cross pattern. Compared with the existing combination structure of base and panel, it is lighter, easier to handle, and easier to expand. In addition, the pallet body has multiple support blocks on the side in contact with the battery pack. These support blocks are arranged at equal intervals in both the horizontal and vertical directions. The distance between two adjacent support blocks forms a retraction area for battery pack handling tools. That is, the pallet body of this solution has retraction areas for handling tools in both the horizontal and vertical directions. In this way, whether forklift handling or hoisting is used, it can ensure that handling tools can be effectively retracted. It can be seen that the turnover pallet of this solution is lightweight, simple in structure, and flexible in use, solving the shortcomings of existing turnover pallets. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0028] This embodiment provides a battery pack turnover tray, such as Figure 2-5 As shown, the turnover pallet includes longitudinal support rods 30 and transverse support rods 40. The transverse support rods 40 and longitudinal support rods 30 are arranged in a cross pattern to form a frame-like pallet body 20. It can be understood that the size of the pallet body 20 should be greater than or equal to the size of the battery pack 10 to ensure that the battery pack 10 can be supported. Multiple support blocks 50 are provided on the contact side between the pallet body 20 and the battery pack 10. The multiple support blocks 50 are used to support the bottom structure of the battery pack 10. The multiple support blocks 50 are arranged at equal intervals in the transverse and longitudinal directions. The gap between two adjacent support blocks 50 forms a retraction area 201 for the battery pack 10 handling tool to retract. That is, the pallet body 20 is provided with support blocks 201 on the front, back, left and right sides. A retraction area 201 is provided for the retraction of handling tools. It can be seen that, compared to existing pallets, this embodiment allows for flexible selection of handling tools based on actual conditions during handling. When a forklift is selected, the forklift's forks can insert into the battery pack 10 from the panel 101 side and lift the battery pack 10. After the battery pack 10 is placed on the pallet body 20, the forklift's forks can retract through the retraction area 201 located on the panel 101 side of the battery pack 10. When a lifting device is selected as the handling tool, the lifting clamps can clamp the bottom of the battery pack 10 on both sides and lift the battery pack 10. After the battery pack 10 is placed on the pallet body 20, the lifting clamps can retract through the retraction area 201 located on both sides of the battery pack 10. Figure 6 As shown.

[0029] In a preferred embodiment, the transverse support rods 40 and the longitudinal support rods 30 are arranged perpendicularly and intersecting each other, with the longitudinal support rods 30 located at the upper end of the transverse support rods 40. The longitudinal support rods 30 fix the multiple transverse support rods 40. In this embodiment, the longitudinal support rods 30 and the transverse support rods 40 are preferably fixed together by bolts. It can be understood that the number of transverse support rods 40 and longitudinal support rods 30 can be selected according to actual needs. In this embodiment, it is preferred that both the transverse support rods 40 and the longitudinal support rods 30 include three rods, and the three rods are arranged at equal intervals.

[0030] The support block 50 is fixed on the longitudinal support rod 30. In this embodiment, the support block 50 is preferably a rectangular block, which is arranged along the length of the longitudinal support rod 30. It can be understood that the support block 50 should include multiple blocks. In this embodiment, at least three support blocks 50 are equidistantly arranged on each longitudinal support rod 30 to achieve balanced support for the battery pack 10. In this embodiment, the height of the support block 50 can be selected according to actual needs to ensure that the fork or clamp of the handling tool can be effectively withdrawn.

[0031] As a preferred embodiment, the upper end face of the longitudinal support rod 30 is provided with a groove 80 arranged along its length direction, and the bottom of the support block 50 is provided with a slider. Preferably, the groove 80 and the slider are adapted to an "I"-shaped structure. The support block 50 slides with the longitudinal support rod 30 through the cooperative cooperation of the slider and the groove 80 to adjust the number of support blocks 50 and the distance between two adjacent support blocks 50. Specifically, according to actual needs, the number and position of the slider on the longitudinal support rod 30 can be adjusted. For example, when the mass of the battery pack 10 is small, the number of support blocks 50 can be reduced in order to reduce the weight of the tray body 20. When the mass of the battery pack 10 is large, the number of support blocks 50 can be increased to increase the arrangement density, thereby improving the support strength of the tray body 20. It can be seen that through the cooperative cooperation of the groove 80 and the slider, the number and position of the slider can be flexibly adjusted, improving the flexibility of use.

[0032] As a preferred embodiment, the bottom of the transverse support rod 40 located below the longitudinal support rod 30 is provided with multiple foot supports 60. The arrangement of the foot supports 60 is the same as that of the support block 50. By setting the foot supports 60, the entire pallet body 20 is supported on the one hand, and a gap is formed between the pallet body 20 and the ground on the other hand, which facilitates the subsequent handling of the pallet body 20. In this embodiment, the height of the foot supports 60 is the same as that of the support block 50, or the height of the foot supports 60 is greater than the thickness of the battery pack 10.

[0033] When the height of the foot support 60 is the same as that of the support block 50, the foot support 60 is only used to support the tray body 20, and when the battery pack 10 is placed on the tray body 20, the tray bodies 20 cannot be stacked together.

[0034] When the height of the foot support 60 is greater than the thickness of the battery pack 10, the foot support 60 is mounted on the transverse support rod 40 located at the edge of the tray body 20, and the size of the tray body 20 is larger than that of the battery pack 10. When the two tray bodies 20 are stacked, the foot support 60 at the bottom of the upper tray body 20 can contact the transverse support rod 40 at the edge of the lower tray body 20. Figure 7-8As shown; specifically, the foot support 60 is set on the horizontal support rod 40 on the edge of the pallet body 20, and the height of the foot support 60 is greater than the thickness of the battery pack 10. When the battery pack 10 is placed on the pallet body 20, if necessary, the two pallet bodies 20 can be stacked, which can save space and facilitate transportation; the two stacked pallet bodies 20 are fixed together by the foot support 60; it is understood that the setting position of the foot support 60 should be based on not affecting the stacking of the two pallet bodies 20.

[0035] As a preferred embodiment, a locking member 70 is provided, which is a right-angled block, and a threaded hole is provided on the right-angled block, such as... Figure 3 As shown, the locking element 70 can lock the support block 50 and the foot support 60 onto the longitudinal support rod 30 and the transverse support rod 40, respectively. Specifically, the locking element 70 is a right-angle block, and its right angle corresponds to the angle between the support block 50 and the longitudinal support rod 30 and the angle between the foot support 60 and the transverse support rod 40. This can improve the tightness of the contact and enhance the stability of the connection. On the other hand, it can reduce the volume of the locking element 70, reduce the weight of the pallet body 20, and improve the compactness and aesthetics of the structure.

[0036] As a preferred embodiment, both the support block 50 and the foot support 60 have honeycomb inner cavities, which effectively reduces weight, and both of their end faces are provided with a wear-resistant layer 90. In this embodiment, the wear-resistant layer 90 is preferably a rubber layer with wear resistance and high surface roughness. By setting the wear-resistant layer 90, the friction between the tray body 20 and the ground and the battery pack 10 can be increased, thus preventing slippage.

[0037] As a preferred embodiment, the support block 50 is fixed to the longitudinal support rod 30 and forms a longitudinal support unit, and the foot support 60 is fixed to the transverse support rod 40 and forms a transverse support unit. Increasing the number of longitudinal and transverse support units can expand the size of the pallet body 20. Specifically, the support block 50 and the longitudinal support rod 30 are considered as a whole unit, and the foot support 60 and the transverse support unit are considered as a whole unit. As needed, longitudinal and transverse support units can be added to the original pallet body 20 to expand the size of the pallet body 20 to meet current needs.

[0038] In this embodiment, for ease of expansion, the two ends of the transverse support unit and the longitudinal support unit are respectively provided with female connectors 100, and the two transverse support units or two longitudinal support units in the same direction are connected end to end through the female connectors 100; of course, the above is a preferred solution of this embodiment. In other specific embodiments of this embodiment, welding, flange connection or other methods can also be used for fixing.

[0039] In this implementation, the female connector 100 is a sleeve-type inner and outer tube, such as... Figure 3 As shown; during installation, the inner sleeves and outer sleeves on the two transverse support units or the two longitudinal support units in the coaxial direction are inserted to extend the length of the transverse support rod 40 or the longitudinal support rod 30. The inner and outer sleeve structure can improve the extension efficiency and restore the initial structure, thereby improving the flexibility and convenience of use. Of course, the above is a preferred structure of the female connector 100 in this embodiment. In other specific embodiments of this embodiment, the female connector 100 can also be an internal or external threaded interface.

[0040] In this preferred embodiment, the transverse support rod 40, longitudinal support rod 30, support block 50, and foot support block 60 constituting the pallet body 20 are all made of aluminum alloy.

[0041] The specific operating principle of this embodiment includes:

[0042] When handling, the handling tools can be flexibly selected according to the actual situation. When a forklift is selected as the handling tool, the forklift's forks can be inserted from the panel 101 side of the battery pack 10 and lift the battery pack 10. After the battery pack 10 is placed on the pallet body 20, the forklift's forks can be withdrawn through the retraction area 201 located on the panel 101 side of the battery pack 10. When a lifting device is selected as the handling tool, the lifting clamp can be clamped on the bottom of the left and right sides of the battery pack 10 and lift the battery pack 10. After the battery pack 10 is placed on the pallet body 20, the lifting clamp can be withdrawn through the retraction area 201 located on the left and right sides of the battery pack 10. After the battery pack 10 is placed, the pallet body 20 can be stacked according to the height of the foot support 60 of the pallet body 20.

[0043] In summary, the pallet body 20 of this embodiment is a frame structure formed by the cross arrangement of transverse support rods 40 and longitudinal support rods 30. Compared with the existing combination structure of base and pallet, it is lighter, easier to handle, and easier to expand. In addition, multiple support blocks 50 are provided on the side of the pallet body 20 that contacts the battery pack 10. The multiple support blocks 50 are arranged at equal intervals in both the transverse and longitudinal directions. The distance between two adjacent support blocks 50 forms a retraction area for the battery pack 10 handling tools. That is, the pallet body 20 of this embodiment has retraction areas for handling tools in both the transverse and longitudinal directions. In this way, whether forklift handling or hoisting handling is used, the handling tools can be effectively retracted. It can be seen that the pallet of this embodiment is lightweight, simple in structure, and flexible in use, solving the shortcomings of existing pallets.
