[0059] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0060] The first direction disclosed in the following description of this application is the length direction of the battery pack transport device provided in this application, the second direction is the width direction of the battery pack transport device provided in this application, and the height direction is the height direction of the battery pack transport device provided in this application.

[0061] Reference Figures 1-18 This application discloses a battery pack transport device, comprising:

[0062] Base component 1;

[0063] Multiple stacked support components 2 form a receiving space for placing a battery pack 4 between two adjacent support components 2 along the height direction. Each support component 2 includes a support member 21 and a limiting member 22. The limiting member 22 is spaced apart along a first direction, and the support member 21 is spaced apart along a second direction. The support member 21 and the limiting member 22 enclose each other to form an annular structure for limiting the battery pack 4 and for supporting the battery pack 4.

[0064] and cover plate assembly 3, which covers the support assembly 2 and is connected to the base assembly 1.

[0065] Reference Figures 1-3 The battery pack transport device disclosed in this application includes a base assembly 1, a support assembly 2, and a cover assembly 3. The base assembly 1 is located at the bottom and serves to support the support assembly 2, the cover assembly 3, and the battery pack 4.

[0066] Support component 2 is placed in Figure 2 Above the base assembly 1. Multiple support assemblies 2 are provided, and the multiple support assemblies 2 are stacked in the height direction. In a specific embodiment of this application, referring to... Figure 1 Five support components 21 are provided, and the five support components 21 are stacked in sequence. Each support component 2 is used to place the battery pack 4, and a receiving space for placing the battery pack 4 is formed between two adjacent support components 2 along the height direction. That is, the adjacent support components 2 in the height direction limit the battery pack 4 in the height direction.

[0067] Please continue to refer to Figure 8 The support assembly 2 includes support members 21 and limiting members 22. The support members 21 are spaced apart along a second direction, and the limiting members 22 are spaced apart along a first direction. The support members 21 and the limiting members 22 form an annular structure for placing the battery pack 4 and for supporting the battery pack 4. The support assembly 2 is used to limit the battery pack 4 on a horizontal plane.

[0068] In this design, on the base assembly 1, the support member 21 and the limiting member 22 can be enclosed to form one or more annular structures according to the size of the battery pack 4. The battery pack 4 is placed within these annular structures, and the support assembly 2 limits the position of the battery pack 4 on the horizontal plane. It should be noted that the distance between two adjacent limiting members 22 is adjusted according to the size of the battery pack in the first direction. Furthermore, this application does not limit the specific number of support members 21 and limiting members 22.

[0069] Preferably, in this embodiment of the application, the support member 21 can be made of plastic material. Compared with the support member 21 made of metal material, the weight of the support member 21 itself is reduced, which significantly reduces the packaging weight of a single battery pack during transportation, thereby improving the net weight full load rate during battery pack transportation.

[0070] Reference Figure 1 The cover assembly 3 is located at the top and covers the support assembly 2 and the battery pack 4. The cover assembly 3 limits the battery pack 4 in the vertical direction.

[0071] This application provides a novel battery pack transport device. The support assembly 2 includes a support member 21 and a limiting member 22, which are assembled into a ring structure to limit the battery pack 4 in a first and second direction, i.e., to limit the battery pack 4 in a horizontal plane. Multiple support assemblies 2 are stacked in the height direction to limit the battery pack 4 in that direction as well. Thus, the support assembly 2 provides support for the battery pack 4 in multiple directions, improving the safety and stability during transport. Furthermore, the support assembly 2 positions the battery pack 4 according to its contour, facilitating its hoisting. The battery pack transport device provided in this application is reusable, reducing resource waste.

[0072] Furthermore, the support assembly 2 can be assembled from support members 21 and limiting members 22. When storing the battery pack transport device, simply separate the support members 21 and limiting members 22, and place multiple support members 21 and limiting members 22 on the base assembly 1. This greatly reduces the height and storage volume of the battery pack transport device after storage.

[0073] In this embodiment, the support member 21 is provided with a first receiving groove 211 along the height direction. The support member 21 forms a first bearing surface 212 and a second bearing surface 213. The first bearing surface 212 and the second bearing surface 213 form a stepped structure at the position of the first receiving groove 211, wherein:

[0074] The first bearing surface 212 is configured to support the battery pack 4;

[0075] The second bearing surface 213 is configured to support the adjacent support member 21.

[0076] Reference Figure 4 The support member 21 has a first receiving groove 211 along the height direction, and the support member 21 forms a first bearing surface 212 and a second bearing surface 213. At the position of the first receiving groove 211, the first bearing surface 212 and the second bearing surface 213 form a stepped structure with the side wall of the first receiving groove 211.

[0077] Reference Figure 9 The battery pack 4 is placed on the first bearing surface 212, which is used to support the battery pack 4.

[0078] Reference Figure 6 and Figure 10 Two adjacent support members 21 in the height direction abut each other through a second bearing surface 213, which supports the adjacent support members 21 in the height direction. This allows multiple support members 21 to be stacked in the height direction.

[0079] By adopting this structure, the weight of the support component 2 is reduced. Furthermore, when the battery pack 4 is placed on the support component 2, its upper surface is higher than the upper surface of the support component, facilitating the hoisting of the battery pack 4. Additionally, it increases the compatibility between the support component 2 and the battery pack 4, expanding the height limit range of the battery pack 4 accommodated by the support component 2.

[0080] In this embodiment of the application, the support component 2 includes two support members 21. The first receiving groove 211 is disposed on one side opposite to the two support members 21 to form a receiving space for accommodating the battery pack 4. The limiting member 22 is disposed between two adjacent support members 21. The two support members 21 and the limiting member 22 enclose each other to form a ring structure.

[0081] In one embodiment of this application, a support member 21 is provided, and a first receiving groove 211 is formed along the height direction of the support member 21, with the first receiving groove 211 located at the center of the support member 21. Wherein:

[0082] The first bearing surface 212 is the bottom wall of the support member 21. The battery pack 4 is placed on the first bearing surface 212, and the first bearing surface 212 is used to support the entire bottom wall of the battery pack 4.

[0083] The sidewall of the first receiving groove 211 and the limiting member 22 form an annular structure, wherein the sidewall of the first receiving groove 211 limits the battery pack 4 in the second direction, and the limiting member 22 limits the battery pack in the first direction.

[0084] The second bearing surface 213 is used to support the adjacent support member 21 in the height direction, and at the same time, the adjacent support member 21 in the height direction limits the battery pack 4 in the height direction.

[0085] Preferably, in order to further increase the compatibility between the bracket assembly 2 and the battery pack 4 and improve the height limit range of the battery pack 4, in this embodiment of the application, the support member 21 is also provided with a receiving groove along the height direction, and the receiving groove and the first receiving groove 211 are respectively located on both sides of the first bearing surface 212.

[0086] In the vertical direction, the receiving groove on the upper support member 21 and the first receiving groove 211 on the lower support member 21 form the receiving space for the battery pack 4. That is, the battery pack 4 is located between two adjacent support members 21 in the vertical direction, such as... Figure 6 As shown.

[0087] Reference Figure 8 In another embodiment of this application, two support members 21 are provided, which are arranged opposite to each other along a second direction, and two first receiving grooves 211 are provided on opposite sides of the two support members 21. Two limiting members 22 are provided between the two support members 21, which are arranged at intervals along a first direction, and the two support members 21 and the two limiting members 22 enclose each other to form a hollow ring structure.

[0088] Reference Figures 8-9 The first receiving groove 211 includes a first bearing surface 212 and sidewalls. The two first bearing surfaces 212 are used to support the edge position of the battery pack 4. The sidewalls of the first receiving groove 211 are used to limit the battery pack 4 in a second direction. The limiting member 22 limits the battery pack 4 in the first direction.

[0089] Reference Figure 6 and Figure 10 The second bearing surface 213 is used to support the adjacent support members 21 in the height direction. In the height direction, the receiving groove on the upper support member 21 and the first receiving groove 211 on the lower support member 21 form the receiving space of the battery pack 4. That is, the battery pack 4 is located between two adjacent support members 21 in the height direction.

[0090] By enclosing the support member 21 and the limiting member 22 to form a ring structure, on the one hand, the weight of the support assembly 2 is further reduced, increasing the load-bearing ratio of the battery pack transport device and thus improving the transport efficiency of the battery pack transport device. On the other hand, it ensures the stable placement of the battery pack 4 on the support assembly 2, improving the stability and safety of the battery pack 4 during transport. In addition, it can increase the compatibility between the support assembly 2 and the battery pack 4, and increase the height limit range of the battery pack 4 accommodated by the support assembly 2.

[0091] In this embodiment of the application, the support member 21 includes a plurality of support units 214, and the plurality of support units 214 are detachably connected along a first direction.

[0092] Reference Figure 5 The support member 21 includes three support units 214, which are arranged sequentially along the first direction. Adjacent support units 214 are positioned by male and female positioning blocks, and adjacent support units 214 are fixedly connected by screw assemblies that pass through the two support units 214 along the height direction.

[0093] Because the battery pack 4 is relatively large, the required support component 21 is also large, thus placing excessive demands on its processing. An excessively long support component 21 is difficult to manufacture. However, the support component 21 provided in this application is composed of multiple detachably connected support units 214. The required length of each support unit 214 is shorter, reducing processing difficulty and solving the problem of the support component 21 being too long to be manufactured. Furthermore, the connection strength of the multiple support units 214 is greater, allowing for more flexible adjustment of the support component 21's length.

[0094] In the embodiments of this application, reference is made to Figure 7 The limiting member 22 includes a connecting rod 220 and a connecting member 221. The connecting member 221 is disposed at both ends of the connecting rod 220 and is connected to the support member 21.

[0095] To accommodate battery packs of different sizes, connecting rods 220 of varying lengths are required. In this embodiment, the connecting rods 220 can be manufactured from extruded plastic parts. Therefore, when different lengths of connecting rods 220 are needed, the extruded plastic parts can be cut to the required length without the need for mold making, greatly improving processing convenience.

[0096] The connector 221 is used to connect with the support member 21, thereby realizing the connection between two oppositely arranged support members 21. Specifically, the connector 221 and the support member 21 can be connected by plugging. For example, the connector 221 can be made of Q235 steel sleeve. Simply insert the connector 221 into the support member 21 to realize the connection between the two, making it easy to connect and disconnect the connector 221 and the support member 21.

[0097] The limiting member 22 provided in this embodiment not only facilitates the connection and separation between itself and the support member 21, but also facilitates the processing of limiting members 22 of different sizes as needed.

[0098] Optionally, the height of the connecting rod 220 in the vertical direction is not greater than the depth of the first receiving groove 211.

[0099] In other words, in the vertical direction, the height of the connecting rod 220 can be less than the depth of the first receiving groove 211. Thus, when the connecting rod 220 is connected to the support member 21, the connecting rod 220 can be placed in the first receiving groove 211, and the side surface of the connecting rod 220 facing away from the first bearing surface 212 is lower than the second bearing surface 213.

[0100] Of course, in the vertical direction, the height of the connecting rod 220 can also be the same as the depth of the first receiving groove 211. In this way, when the connecting rod 220 is connected to the support member 21, the side surface of the connecting rod 220 facing away from the first bearing surface 212 is flush with the second bearing surface 213.

[0101] By limiting the relationship between the height of the connecting rod 220 in the height direction and the depth of the first receiving groove 211, it is ensured that the side of the connecting rod 220 away from the first bearing surface 212 is not higher than the second bearing surface 213. Thus, when the support members 21 are stacked, two adjacent support members 21 can be connected smoothly, improving the stability of the support members 21 during the stacking process.

[0102] In this embodiment of the application, the support member 21 is provided with a plurality of first limiting holes 215, the plurality of first limiting holes 215 are arranged along a first direction, and the first limiting holes 215 are connected to the connector 221.

[0103] To limit the battery pack in the first direction, at least two limiting members 22 are provided between the two support members 21, and the distance between the limiting members 22 needs to be adjusted according to the size of the battery pack 4. To accommodate battery packs of different sizes, this application provides a plurality of first limiting holes 215 on the support member 21.

[0104] Reference Figure 4 The first limiting hole 215 is provided at both ends of the support member 21 along the first direction, that is Figure 5 In the middle, the first limiting holes 215 are distributed on the support units 214 located on both sides. Each support unit 214 is provided with multiple first limiting holes 215, thereby realizing the adjustment of the connection position between the limiting member 22 and the support member 21, and further realizing the position adjustment between the two first limiting members 22 to adapt to battery packs of different sizes.

[0105] The support component 2 provided in this application can adapt to battery packs of different sizes in the first direction by changing the distance between the two limiting members 22, thereby improving its applicability.

[0106] In this embodiment of the application, the support member 21 is provided with a second limiting hole 216, the second limiting hole 216 is connected to the connector 221, and the second limiting hole 216 is disposed between two first limiting holes 215.

[0107] The first limiting hole 215 cooperates with the second limiting hole 216 to realize the storage of the limiting member 22.

[0108] Since the support assembly 2 needs to be stored when the battery pack 4 is not placed there, to improve storage convenience and save storage space, the limiting member 22 can be placed in the first receiving groove 211 along the first direction. That is, one end of the limiting member 22 cooperates with the first limiting hole 215, and the other end of the limiting member 22 cooperates with the second limiting hole 216, thereby realizing the connection between the limiting member 22 and the support member 21.

[0109] Preferably, refer to Figures 4-5 In this application, the second limiting hole 216 is located at the middle position of the support member 21, and the second limiting hole 216 is set as an oblong hole, wherein the oblong direction of the second limiting hole 216 is the first direction. Thus, the support member 21 can accommodate limiting members 22 of different sizes.

[0110] In this embodiment of the application, the base assembly 1 includes a base body 11 and a first connecting rod 12 disposed on the base body 11, wherein the first connecting rod 12 is configured to limit the support assembly 2.

[0111] Reference Figure 2 The base assembly 1 includes a base body 11 and a first connecting rod 12 disposed on the base body 11. The base body 11 is used to place the support assembly 2, and the first connecting rod 12 is used to cooperate with the support assembly 2 to limit the position of the support assembly 2 on the base body 11.

[0112] In one specific embodiment of this application, the supporting first connecting rods 12 are symmetrically distributed on both sides of the base body 11. For example, the first connecting rods 12 cooperate with the support member 21 to limit the support member 21 in a second direction. Alternatively, the first connecting rods 12 cooperate with the limiting member 22 to limit the limiting member 22 in a first direction. Since the support member 21 and the limiting member 22 are connected as a whole, the first connecting rods 12 limit the support assembly 2. Here, the first direction is the length direction of the battery pack transport device, and the second direction is the width direction of the battery pack transport device.

[0113] The support member 21 and the first connecting rod 12 form a limiting fit to realize the installation and positioning of the support member 21 on the base body 11.

[0114] It should be noted that the base body 11 can be set as a single metal plate. Of course, referring to... Figure 3The base body 11 can also be configured as a two-layer structure, comprising a perforated first layer plate and a second layer plate covering the surface of the first layer plate. By configuring the base body 11 as a two-layer structure, the strength of the base body 11 can be ensured while minimizing its weight, thereby increasing the load capacity during transportation.

[0115] In addition, a forklift frame is connected to one side of the base body 11, that is... Figure 2 A forklift frame is provided on the lower surface of the base body 11.

[0116] In this embodiment of the application, the support member 21 is provided with a positioning groove 210 along the height direction, and the positioning groove 210 is configured to cooperate with the first connecting rod 12.

[0117] Reference Figure 4 The support member 21 has a positioning groove 210, for example... Figure 8 As shown, the support member 21 has a positioning groove 210 along the height direction, and the positioning groove 210 is configured to cooperate with the first connecting rod 12. It should be noted that the height direction can be a direction perpendicular to the plane of the base body 11.

[0118] Of course, other limiting structures can also be provided on the support member to achieve the limiting between the support member 21 and the first connecting rod 12. This application does not limit the limiting cooperation method between the support member 21 and the first connecting rod 12.

[0119] In one specific embodiment of this application, reference is made to... Figure 4 and Figure 8 The base assembly 1 includes six first connecting rods 12, and the support assembly 2 includes two support members 21. Each support member 21 has three positioning slots 210. The three positioning slots 210 on one support member 21 are distributed along a first direction, and the two support members 21 are spaced apart along a second direction. There are six first connecting rods 12, each corresponding to a positioning slot 210. Specifically, the length of the first connecting rod 12 is greater than the thickness of the support member 21, so that the first connecting rod 12 can limit the movement of multiple stacked support members 21.

[0120] This application, by setting the positioning groove 210, facilitates the support and limiting of the battery pack 4. This reduces the overall height of the battery pack 4 and the support 21 in the height direction after the battery pack 4 is placed on the support member 21, thereby reducing the overall height of the stacked support components 2 and saving storage space. Furthermore, when the support members 21 are stacked in the height direction, the upper support member 21 can limit the height of the lower battery pack 4 in the height direction.

[0121] In the embodiments of this application, reference is made to Figure 11The cover plate assembly 3 includes a cover plate body 31 and a second connecting rod 32. The cover plate body 31 covers the support assembly 2, and the second connecting rod 32 is inserted into the first connecting rod 12. The cover plate assembly 3 is used to limit the battery pack 4 in the height direction.

[0122] In one specific embodiment of this application, reference is made to... Figures 10-11 The system comprises six first connecting rods 11 and six second connecting rods 32, with each second connecting rod 32 corresponding to a first connecting rod 12, and the second connecting rods 32 and 12 are interlocked. Specifically, the first connecting rod 12 can be a hollow tubular structure, with the second connecting rod 32 inserted inside it. Alternatively, the second connecting rod 32 can also be a hollow tubular structure, with the first connecting rod 12 inserted inside it. This application does not limit the specific structure of the first connecting rod 12 and the second connecting rod 32.

[0123] By setting the first connecting rod 12 of the base assembly 1 and the second connecting rod 32 of the cover plate assembly 3 to be inserted and cooperated, the battery pack transport device is made into a whole. Even if the battery pack 4 passes through sudden braking and speed bumps during transportation, it will not slip, which further improves the safety of the battery pack 4 during transportation.

[0124] In this embodiment of the application, the cover plate assembly 3 further includes a connecting sleeve 33 and a positioning member 34, wherein the connecting sleeve 33 and the second connecting rod 32 are slidably connected through the positioning member 34.

[0125] Reference Figure 12 A connecting sleeve 33 is provided on the cover plate body 31, and the connecting sleeve 33 is provided in a one-to-one correspondence with the second connecting rod 32. The connecting sleeve 33 is a hollow structure and is sleeved on the outer periphery of the second connecting rod 32. The positioning member 34 passes through both the second connecting rod 32 and the connecting sleeve 33 to connect the two. The positioning member 34 can be a screw assembly.

[0126] In practical use, different numbers of support components 2 need to be set according to the actual situation. In order to ensure the cooperation between the second link 32 and the first link 12, it is necessary to use second link 32 of different lengths. Therefore, in this application, a connecting sleeve 33 is set to install the second link 32 onto the cover plate body 31, which facilitates the connection between the second link 32 and the cover plate body 31, as well as the replacement of second link 32 of different sizes.

[0127] Specifically, the second connecting rod 32 has a through groove 320 along the height direction, the positioning member 34 passes through the through groove 320, and the connecting sleeve 33 is slidably connected to the second connecting rod 32.

[0128] Reference Figures 11-13The second connecting rod 32 has a through groove 320 that extends along the height direction, which is also the axial direction of the second connecting rod 32. The positioning member 34 passes through the connecting sleeve 33 and the through groove 320 to connect the second connecting rod 32 with the connecting sleeve 33.

[0129] By employing this structure, the positioning element 34 can slide along the height direction within the through groove 320, meaning the second connecting rod 32 can slide freely relative to the connecting sleeve 33. Thus, when the cover plate assembly 3 needs to be placed on the support assembly 2, under the influence of gravity, the second connecting rod 32 slides relative to the connecting sleeve 33, increasing the total length of the second connecting rod 32 and the connecting sleeve 33, and inserting into the first connecting rod 12. When the cover plate assembly 3 needs to be stored, it is flipped over, and again under the influence of gravity, the total length between the second connecting rod 32 and the connecting sleeve 33 decreases, thereby achieving automatic adjustment of the position of the first connecting rod 12.

[0130] In this embodiment of the application, a positioning rod 35 is provided on one side of the cover plate body 31, and a second receiving groove 217 is provided on the support member 21 to cooperate with the positioning rod 35.

[0131] The positioning rod 35 can be provided in one or more ways. This application does not limit the number or shape of the positioning rod 35, as long as the positioning rod 35 cooperates with the second receiving groove 217 to limit the position of the support member 21 when the support member 21 is placed on the cover plate body 31.

[0132] Reference Figures 14-15 In this embodiment of the application, three positioning rods 35 are provided, the three positioning rods 35 are distributed at intervals along the first direction, and the positioning rods 35 are located between two second connecting rods 220 that are arranged opposite to each other along the second direction.

[0133] When it is necessary to store the cover assembly 3, such as Figure 16 As shown, the cover plate body 31 is placed on the ground, and multiple support members 21 are stacked on the cover plate body 31. Among them, the second connecting rod 32 passes through the limiting groove, and the positioning rod 35 cooperates with the second receiving groove 217 to limit the position of the support member 21.

[0134] In this embodiment of the application, the base assembly 1 further includes a storage sleeve 14, which is connected to the first connecting rod 12 and is inserted into the second connecting rod 32 to realize the stacked connection of the base assembly 1 and the cover plate assembly 3.

[0135] Reference Figure 16The adjusting component 13 is fixedly connected to the base body 11. One end of the adjusting component 13 is rotatably connected to the first connecting rod 12, and the other end of the adjusting component 13 is fixedly connected to the storage sleeve 14. The storage sleeve 14 and the first connecting rod 12 are respectively located on both sides of the base body 11.

[0136] Reference Figure 18 The storage sleeve 14 is inserted into the second connecting rod 32. In this way, when the battery pack transport device needs to be stored, the base body 11 and the cover body 31 can be alternately stacked by inserting the storage sleeve 14 into the second connecting rod 32, thereby significantly reducing the volume occupied after storage and improving the storage effect.

[0137] In this embodiment of the application, the base assembly 1 further includes an adjusting member 13, which is configured to rotate the first connecting rod 12 to a folded state extending along the second direction, and also to rotate the first connecting rod 12 to a use state extending along the height direction.

[0138] Since the first link 12 needs to cooperate with the multi-layer support assembly 2 to achieve positioning, the length of the first link 12 is usually relatively long, which makes it difficult to store the first link 12 when not in use.

[0139] Therefore, this application provides an adjusting member 13. When the first connecting rod 12 is needed, the first connecting rod 12 rotates relative to the adjusting member 13 to extend along the height direction, so as to achieve a limiting engagement between the first connecting rod 12 and the multi-layer stacked support assembly 2. When the battery pack transport assembly needs to be stored, the first connecting rod 12 is rotated to a folded state extending along the second direction, that is, the first connecting rod 12 is rotated to the surface of the base body 11, so as to achieve storage of the first connecting rod 12.

[0140] In this embodiment, the adjusting member 13 includes a sleeve rod 130, a rotating shaft 131, and a locking member. The sleeve rod 130 is fixedly connected to the base body 11. One end of the first connecting rod 12 is disposed inside the sleeve rod 130. The rotating shaft 131 passes through the sleeve rod 130 and the first connecting rod 12 in a first direction. The locking member is disposed on the rotating shaft 131 and is configured to position the sleeve rod 130 and the first connecting rod 12.

[0141] Specifically, refer to Figure 16 The base body is provided with a sleeve 130, which corresponds one-to-one with the first connecting rod 12. The sleeve 130 can be fixedly connected to the base body 11 by welding or other means. The sleeve 130 has an opening on one side facing the center of the base body 11, and the cross-section of the sleeve 130 in the direction perpendicular to the height is C-shaped.

[0142] One end of the first connecting rod 12 is located inside the sleeve rod 130. A rotating shaft 131 passes through both the first connecting rod 12 and the sleeve rod 130, and the first connecting rod 12 and the sleeve rod 130 are rotatably connected via the rotating shaft 131. A locking element is connected to the rotating shaft 131 to position the first connecting rod 12 and the sleeve rod 130. The locking element can be a nut, and it is threadedly fixed to the rotating shaft 131.

[0143] Specifically, the sleeve 130 is provided with at least two mounting holes 1301, which are spaced apart along the height direction, and the rotating shaft 131 passes through the mounting holes 1301 and is connected to the locking member.

[0144] Reference Figure 16 The sleeve 130 is provided with two mounting holes 1301, which are at different heights in the vertical direction. The mounting holes 1301 are used for the rotating shaft 131 to pass through.

[0145] This application provides mounting holes 1301 on the sleeve rod 130, and the mounting holes 1301 have different heights in the height direction. This is beneficial because after all the first connecting rods 12 are folded, the two first connecting rods 12 that are arranged opposite each other in the second direction are stacked together. That is, the projections of the two first connecting rods 12 on the base body 11 are on the same straight line. This allows the first connecting rods 12 to be symmetrically distributed, thereby improving the convenience of subsequent insertion and engagement between the first connecting rods 12 and the second connecting rod 32.

[0146] In this embodiment of the application, the support member 21 is provided with a third receiving groove 218 along the second direction. The third receiving groove 218 is located on the side of the support member 21 away from the first receiving groove 211. The third receiving groove 218 is configured to avoid the first connecting rod 12 in the folded state.

[0147] Reference Figures 4-5 The support member 21 has a third receiving groove 218 along the second direction. The third receiving groove 218 is located on the side of the support member 21 away from the first receiving groove 211. That is, the first receiving groove 211 and the third receiving groove 218 are distributed on both sides of the support member 21.

[0148] Reference Figures 16-17 When the first link 12 is in the folded state, the third receiving groove 218 can avoid the first link 12. The position of the third receiving groove 218 corresponds to the position of the first link 12 after it is folded.

[0149] When storing, first rotate the first connecting rod 12 to the folded state, and then place the support member 21 on the base body 11. The third receiving groove 218 can also limit the position of the support member 21 by the first connecting rod 12, thereby improving the stability of the support member 21 when it is placed on the base body 11 for storage.

[0150] The following combination Figures 8-10 The steps for placing the battery pack 4 in the battery pack transport device provided in this application are described below:

[0151] Step 1: Place the base assembly 1 on the ground and adjust the first connecting rod 12 to be perpendicular to the base body 11.

[0152] Step 2, place support component 2. (Refer to...) Figure 8 Two support members 21 and two limiting members 22 are placed on the base body 11. The two support members 21 are spaced apart along the second direction, and the positioning grooves 210 of the two support members 21 engage with the first connecting rod 12. The two limiting members 22 are respectively located at the ends of the support members 21 along the first direction. The two support members 21 and the two limiting members 22 engage and enclose a space for accommodating the battery pack 4.

[0153] Step 3, place the battery pack. (Refer to...) Figure 9 The battery pack 4 is placed in the space enclosed by the support member 21 and the limiting member 22, wherein the battery pack 4 is placed in the first receiving groove 211 and the battery pack 4 is in contact with the first bearing surface 212, thus completing the placement of one layer of battery pack 4.

[0154] Step 4, as follows Figure 10 As shown, repeat steps 2-3 to sequentially hoist the battery pack 4 to the set number of layers. Specifically, a support member 21 is placed on top of the support component 2 in step 2, with the lower surface of the support member 21 aligning with the second bearing surface 213 of the support member 21 below it. The positioning groove 210 of the support member 21 is moved to a position that engages with the first connecting rod 12. Then, a limiting member 22 is placed between the support members 21 to complete the installation of the support component 2, achieving the stacking of the two support components 2 in the height direction. The battery pack 4 is then placed on this layer of support component 2, and the placement of multiple layers of battery pack 4 is completed sequentially.

[0155] Step 5: Cover the support assembly 2 and battery pack 4 with a cover plate assembly 3, wherein the second connecting rod 32 is inserted into the first connecting rod 12, and then use packing straps to bind the cover plate assembly 3 and the base assembly 1 to prevent the cover plate assembly 3 from jumping out of the support assembly 2.

[0156] The following combination Figures 14-18 The following describes the storage process of the battery pack transport device provided in this application:

[0157] Step 1, as follows Figure 14 As shown, the cover plate assembly 3 is removed and flipped over to be placed on the ground, that is, the cover plate body 31 is in contact with the ground.

[0158] Step 2, as follows Figure 15 As shown, the battery pack 4, the limiting member 22 and the support member 21 are retrieved in sequence. The support member 21 is placed side by side on the cover plate body 31, wherein the second connecting rod 32 is inserted into the positioning groove 210 on the support member 21, and the limiting member 22 is placed in the first receiving groove 211 along the first direction.

[0159] Step 3, as follows Figure 16 As shown, the first connecting rod 12 of the empty base assembly 1 is rotated to a folded state, and then the support member 21 and the limiting member 22 are placed on the base body 11. The third receiving groove 218 of the support member 21 is engaged with the first connecting rod 12, and the limiting member 22 is placed in the first receiving groove 211 of the support member 21.

[0160] Step 4, as follows Figure 17 As shown, the base assembly 1, which contains the support member 21 and the limiting member 22, is stacked on the cover plate assembly 3, wherein the storage sleeve 14 is inserted into the second connecting rod 32.

[0161] Step 5: Repeat steps 1-4 in sequence, alternately stacking the cover plate assembly 3 with support component 2 and the base assembly 1, as follows. Figure 18 As shown, the battery pack transport device has been successfully recovered.

[0162] The battery pack conveying structure provided in this application can significantly reduce the volume of the battery pack after recycling by coordinating the various structures, thereby reducing the transportation cost of the battery pack 4.

[0163] Furthermore, the battery pack transport device provided in this application can be used to transport battery packs 4 of different specifications, realizing the use of a single battery pack transport device for multiple battery packs, which greatly reduces the waste of equipment caused by the rapid pace of battery pack replacement in the current market.
