Description

Technical Field

[0001] The utility model belongs to the technical field of battery pack handling equipment, and relates to an adjustable flexible battery pack transportation shelf. Background Art

[0002] As the power supply system of the entire electric vehicle, the battery pack plays a particularly important role, and the safety of the battery pack is also crucial. Different vehicle models have different requirements, so the requirements for the battery pack are also different.

[0003] In order to relieve the production pressure of each enterprise and reduce costs, some large enterprises also hand over the power battery pack to professional battery suppliers for production, and finally install it on the whole vehicle. This inevitably involves the long-distance and short-distance transportation of the battery pack from the battery manufacturer to the vehicle manufacturer.

[0004] On the one hand, the power battery should be avoided from shaking as much as possible during transportation to ensure its safety and prevent the deterioration or short circuit of electrochemical substances due to collision, pollution, etc., and avoid the combustion or explosion of the battery pack; on the other hand, for enterprises, it is necessary to make a set of battery pack transportation shelves be able to transport various types and sizes of battery packs as much as possible, so as to avoid the transportation shelves for various specifications of battery packs, resulting in too high transportation costs.

[0005] The existing reference CN202010120135.7, a battery pack transportation device, states that a limit frame is used for limiting. However, on the one hand, the limitation of the overall height of the battery pack is not in place, and on the other hand, the limiting components cannot be adjusted. Therefore, for many different types and sizes of battery packs, the limit cannot be adjusted. In addition, the existing battery pack transportation shelves will use a whole piece of backing plate material, but the material is relatively soft. After being heavily pressed by the battery pack, the material plane is prone to unevenness. When the transportation shelf is stored outdoors, there will be water accumulation problems on the large EVA plane.

[0006] In summary, an adjustable flexible battery pack transportation shelf of the present utility model is proposed. Summary of the Invention

A movable base 42 is installed in the guide groove. A stopper limiting plate 43 is installed on the movable base 42. A polyurethane plate 44 is installed on the side of the stopper limiting plate 43 opposite to the EVA cushion plate 3. The polyurethane plate 44 has elasticity and wear resistance effects and can abut against the battery pack housing to form a limiting effect. The top height of the polyurethane plate 44 is 10 mm higher than the top height of the stopper limiting plate 43.

[0054] A first connecting hole 45 is formed at the bottom of the guide groove. There are multiple groups of the first connecting holes 45 and they are arranged along the axial direction of the limiting guide rail strip 41.

For the improved support member 2, the size of the fixing block is increased, the length of the welding joint is increased, and a steel pipe 28 is added to connect the column 23 and the fixing block 27 for connecting and lifting, so as to distribute the external force, reduce the unit welding pressure, and increase the service life of the transport shelf.

[0062] Embodiment 3

[0063] As Figure 11 and Figure 12 As shown in Figure 12 , another implementation of the present utility model is based on Embodiment 1. A smooth portion 4211 and a threaded portion 4212 are provided on the connecting threaded rod 421. A connecting bearing 425 is installed in the central hole 423. The smooth portion 4211 is fixedly connected to the inner ring of the connecting bearing 425, and the outer ring of the connecting bearing 425 is fixedly connected to the inner wall of the central hole 423. A support short column is provided at the bottom of the frame 1, and a balance plate is installed at the bottom of the support short column. The end of the balance plate is connected to the bottom seat 21. In this embodiment, after the smooth portion 4211 is fixed to the inner ring of the connecting bearing, the fixed connection between the connecting threaded rod 421 and the moving bottom plate 422 is realized.
