[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figure 1-4 , Figure 1 This is a partial structural diagram of a fuel cell stack transportation device provided by an embodiment of the present invention; Figure 2 yes Figure 1 Schematic diagram of the structure of the CLP stack transport assembly; Figure 3 yes Figure 2 Schematic diagram of the structure of the fuel cell stack and the fuel cell transport assembly separated; Figure 4 yes Figure 3 A magnified view of center.

[0029] like Figure 1-4 As shown, an embodiment of the present invention provides a stack transport assembly and a stack transport device. The stack transport device includes a multi-layer stack transport assembly. There is no limit on the number of stack transport assemblies on each layer, and the number can be one, two, or more. The stack transport assembly includes a base and two sets of supports 2 fixed to the base. During transportation, the base can be used to fix, carry, and lift the stack 1 as a whole, and the two sets of supports 2 support and limit the stack 1.

[0030] Two groups of supports 2 are symmetrically arranged on both sides of the fuel cell stack 1, and each support 2 includes a first support surface and a second support surface, wherein the first support surface is parallel to the side end surface of the end plate 11 of the fuel cell stack 1, and the first support surfaces of the two groups of supports 2 limit the lateral movement of the end plate 11 from both sides of the end plate 11, wherein an end plate 11 is respectively provided at the front and rear ends of the fuel cell stack 1, and the lateral direction refers to the direction perpendicular to the front and rear, and each group of supports 2 limits the fuel cell stack 1 by the two end plates 11, thereby limiting the lateral movement of the fuel cell stack 1; and the second support surface is arranged at the bottom end of the first support surface, which is used to support the end plate 11, that is, used to support the fuel cell stack 1 from the bottom.

[0031] When the battery stack 1 is placed on the battery stack transport assembly, the second support surface supports the end plate 11. Combined with the first support surface limiting the end plate 11, it can effectively prevent the battery stack 1 from tipping over during transportation, thereby preventing the battery stack 1 from being involved in, colliding with, or even damaging surrounding pipelines and other components.

[0032] In the above embodiment, if Figure 4 As shown, the side end face of the end plate 11 includes a first end face 111 and a second end face 112, wherein the second end face 112 is arranged at the bottom end of the first end face 111 and is inclined. Accordingly, the first supporting surface of the support 2 is parallel to the first end face 111, and the second supporting surface is parallel to the second end face 112 and is used to support the second end face 112. After the battery stack 1 is placed on the battery stack transport assembly, the second end face 112 abuts against the second supporting surface. The second supporting surface provides a vertical upward supporting force to the end plate 11 while also providing a lateral inward force (referring to the side toward the end plate 11) to limit the lateral movement of the end plate 11. At the same time, the first supporting surface limits the first end face 111 from the side, which can effectively prevent the battery stack 1 from tipping over, thereby preventing the battery stack 1 from being involved in, colliding with, or even damaging surrounding pipelines and other components.

[0033] Of course, in this embodiment, the angle between the first end face 111 and the second end face 112 can also be set to 90°. For example, if the second end face 112 is the bottom surface of the end plate 11, then the angle between the second support surface and the first support surface is 90°. The second support surface can also support the second end face 112, and the first end face 111 prevents the second end face 112 from moving or falling laterally by abutting against the first support surface. However, the second end face 112 is tilted, that is, the angle between the first end face 111 and the second end face 112 is between 90-180°, so that the second support surface can support the second end face 112 while also limiting the end plate 11 laterally to prevent it from shifting laterally. At this time, in the installed state, the first support surface can abut against the first end face 111, and there can be a certain gap between the first support surface and the first end face 111, which is convenient for installation.

[0034] In the above embodiment, the side end surface of the end plate 11 further includes a third end surface 113 located at the bottom end of the second end surface 112, and the support 2 further includes a third support surface connected to the bottom of the second support surface, and the third support surface is parallel to the third end surface 113. In other words, the support 2 supports and limits the end plate 11 through three sections. At this time, the first support surface, the second support surface, and the third support surface form a "Z"-shaped limiting support surface. There are two bends between the three support surfaces, which can further prevent the stack 1 from overturning and provide more stable positioning.

[0035] In the above embodiment, the support 2 includes a support plate 21 fixed to the base. The support plate 21 includes a first baffle 211 with a first support surface, a second baffle 212 with a second support surface, and a third baffle 213 with a third support surface. In other words, the support plate 21 is a single, integral plate-like structure, which effectively reduces the weight of the support 2, making the stack transport assembly lightweight, convenient, and economical to transport.

[0036] In the above embodiment, the support 2 further includes two brackets 22, and the two ends of the support plate 21 are fixed to the base through the brackets 22. Of course, in this embodiment, the two ends of the support plate 21 can also be fixed to the base by welding or bolting. The support plate 21 is fixed to the base through the brackets 22. Figure 1-3 As shown, the contact area can be increased, making the connection between the support plate 21 and the base more stable.

[0037] In addition, in order to make the structure more stable, the support 2 is further provided with a rib plate 23 , which is connected between the second baffle 212 and the third baffle 213 , so as to improve the overall structural strength while ensuring lightweight.

[0038] In the above embodiment, the side surfaces of the support plate 21 and the end plate 11 are both provided with fixing holes, and the two are fixed by bolts. Of course, in this embodiment, the support plate 21 and the end plate 11 only have abutment effect. That is, during transportation, the end plate 11 of the stack 1 is only placed above the support 2, and there is no fixed connection between the two. In this embodiment, the bolt connection is used to further enhance the stability between the two. At the same time, due to the thin thickness of the connecting plate, it can be provided with a through hole, and the side wall of the end plate 11 can be provided with a corresponding blind hole, which is a threaded hole. The two can be fixed by bolts or screws.

[0039] At the same time, the bolt mounting hole of the connecting plate is a strip hole 24 , the length direction of the strip hole 24 is consistent with the length direction of the supporting plate 21 , and the strip hole 24 facilitates the installation between the two and reduces the requirements for processing accuracy.

[0040] In addition, there are no specific requirements for the location of the bolt mounting holes of the connecting plate, such as Figure 3 As shown, in this embodiment, the bolt mounting hole is provided on the second baffle 212, and the bolt is connected to the second baffle 212 and the second end face 112. The bolt mounting hole can also be provided on the first baffle 211 or the third baffle 213, and correspondingly, the bolt can be connected to the first baffle 211 and the first end face 111 or the third baffle 213 and the third end face 113.

[0041] like Figure 2 As shown, in the above embodiment, the base includes two parallel beams 3, and the two ends of the support 2 are respectively fixed to the two beams 3. The two supports 2 and the two beams 3 can be enclosed to form a square frame. Compared with the structure in which the supports 2 are provided as two separate structures fixed to the base and used to limit the end plate 11, this facilitates the installation of the battery stack 1. During installation, the battery stack 1 only needs to be pushed in a direction parallel to the two support plates 21. During the pushing process, the three support surfaces guide the battery stack 1, facilitating smooth installation.

[0042] like Figure 1 As shown, in the above embodiment, each layer of the battery stack transport device is provided with multiple battery stack transport assemblies arranged side by side, wherein the bases of each battery stack transport assembly are connected in sequence, and the connection method between the bases is not limited. In this embodiment, each layer of the battery stack transport device is provided with two transverse frames, and the two transverse frames form the crossbeam 3 of the base in each transport assembly, that is, the bases of the battery stack transport assemblies on the same layer are an integrated structure, which can simplify the overall structure while ensuring the stability of the overall structure.

[0043] In addition, vertical frames 5 are provided between each layer of the battery stack transport device to support the battery stack transport components of each layer. The horizontal frame and the vertical frame 5 divide the battery stack transport device into multiple placement areas. Each placement area is provided with two sets of brackets 22. During installation, the battery stack 1 can be pushed into each placement area along the direction of the bracket 22. The installation is more convenient and the floor space is reduced.

[0044] In the above embodiment, if Figure 3 As shown, a reinforcement plate 4 is provided between the crossbeam 3 and the adjacent support 2. The reinforcement plate 4 is located within the frame to make the base structure more stable. At the same time, it strengthens the connection strength between the support 2 and the base, improving overall stability. Compared with a structure with a base made of steel plate, this structure can effectively reduce the overall weight, reduce the transportation load, and improve economic efficiency.

[0045] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
