Description

Technical Field

[0001] The utility model relates to the technical field of battery packaging, in particular to an integrally packaged battery cluster. Background Art

[0002] Currently, battery clusters are mostly shipped in separate packages. Specifically, the battery packs, high-voltage boxes, and accessories (wiring harnesses, terminal connectors, and other components) within the battery cluster are packaged and shipped separately in wooden and cardboard boxes. Battery racks are transported using pallets and strapping. This packaging method is extremely inefficient, expensive, and requires significant floor space after packaging. Furthermore, after shipping the product to the customer, the battery packs and high-voltage boxes need to be reassembled and rewired, significantly wasting labor costs. However, the assembled battery cluster is unstable due to gaps between the battery racks and battery packs. Directly transporting the battery cluster as a whole can lead to collisions between adjacent battery packs, between battery racks, and between battery racks and external objects due to bumps and shaking, resulting in component damage. Utility Model Content

[0003] The purpose of the present utility model is to overcome the technical problem in the prior art that direct transportation of battery clusters may cause unstable internal structure assembly and may lead to collision and damage of components due to bumps and shaking during transportation, and to provide a battery cluster in an integral package.

[0004] In a first aspect, the present invention provides an integrally packaged battery cluster, comprising a battery rack, a plurality of battery packs, a first buffer, a second buffer, and a third buffer, wherein the plurality of battery packs are mounted in the battery rack, the first buffer is disposed between two adjacent battery packs, the second buffer is disposed between the battery rack and the battery packs, and the third buffer is disposed on the outside of the battery rack.

[0005] The existing technology usually splits the battery cluster into multiple modules for packaging and transportation, which results in low efficiency and technical defects such as the need for reassembly after transportation. Directly transporting the battery cluster as a whole will also result in unstable internal structure assembly, and technical problems such as bumps and shaking during transportation will cause collisions and damage to the components. The overall packaged battery cluster of the utility model can be used to transport the assembled battery cluster as a whole. By installing buffers at multiple positions in the battery cluster, such as between adjacent battery packs, between the bottom of the battery pack and the battery rack, and on the top of the battery rack for shock absorption, it can avoid collisions between battery packs, between the battery pack and the battery rack, and between the battery rack and other objects placed on it during transportation due to bumps and damage, thereby ensuring that the overall structure of the battery cluster and various components remain intact during transportation.

[0006] In addition, the present invention can save transportation space by packaging and transporting the battery cluster as a whole, and more battery clusters can be stored in the same volume of space; at the same time, the use of packaging materials is reduced, and packaging costs are reduced; after the battery cluster is transported as a whole to the destination, it can be used directly after unpacking, without the need to disassemble the package before transportation or reassemble it after transportation, which reduces the installation process of the battery cluster, reduces the installation cost, and improves the packaging and transportation efficiency.

[0007] Preferably, it further comprises a bottom plate and a packing box, wherein the packing box covers the outside of the battery rack, and the bottom plate abuts against the battery rack and is fixedly connected to the packing box to seal the packing box.

[0008] The packaging box cover is used outside the assembled battery cluster to form an independent transportation space for a single battery cluster. In the scenario of transporting multiple battery clusters, sufficient spacing can be formed between adjacent battery clusters, thereby avoiding collisions between battery clusters and causing damage.

[0009] Preferably, the bottom plate is a logistics plate.

[0010] Preferably, it further comprises a first strapping belt strapped to the outside of the packaging box and the bottom plate.

[0011] Preferably, the first strapping tape is wrapped around the packaging box and the bottom plate at least three times.

[0012] Preferably, a plurality of the first strapping belts are arranged at intervals along a first direction and a second direction of the packaging box, respectively, wherein the first direction and the second direction are arranged crosswise.

[0013] Preferably, the first strapping belt arranged along the first direction and the first strapping belt arranged along the second direction are staggered with each other.

[0014] After the packing box is covered on the battery cluster, the packing box and the bottom plate can be wrapped with strapping tape to fix the packing box and the bottom plate, thereby fixing the battery cluster in the packing box; the strapping tape is used to tie the packing box along the first direction and the second direction and arranged at intervals, and tied on the packing box at least three times, which can further improve the stability of the packing box and prevent the bottom plate from falling off during transportation. Here, the first direction and the second direction are Figure 3 The length and width directions of the packaging box are shown in .

[0015] Preferably, it further comprises a limiting assembly mounted on the base plate, wherein the limiting assembly abuts against the outer peripheral side of the battery rack and is used to limit the relative movement between the battery rack and the base plate.

[0016] Preferably, the limiting assembly includes a plurality of limiting blocks arranged in the circumferential direction of the battery rack.

[0017] During transportation, the battery cluster may shift on the base plate due to bumps. In order to maintain the relative fixation between the battery cluster and the base plate, a limit assembly can be installed on the base plate to limit the battery cluster; specifically, the limit assembly may include multiple limit blocks, which can be installed at the bottom edge of the battery cluster and distributed along the circumference of the battery cluster. They can abut the battery cluster and be fixed on the base plate at the same time, which can limit the lateral movement of the battery cluster relative to the base plate so that it remains relatively fixed with the base plate.

[0018] Preferably, it further comprises a plurality of second strapping belts bundled outside the battery rack and the bottom plate, and the plurality of second strapping belts correspond one-to-one to the plurality of limiting blocks.

[0019] Preferably, a plurality of the second strapping belts are arranged at intervals along the third direction and the fourth direction of the battery rack, respectively, wherein the third direction and the fourth direction are arranged crosswise.

[0020] After placing the battery cluster on the base plate, the battery cluster and the base plate need to be wrapped together with a strapping tape to form a fixed whole, so as to avoid accidents such as the battery cluster falling off or tipping over from the base plate due to bumps during transportation; specifically, a second strapping tape can be used for strapping at the corresponding positions of several limit blocks. Since the force point between the limit block and the battery cluster is located at the bottom of the battery cluster, tying the second strapping tape on the battery cluster at the corresponding position of the limit block can make the force point between the second strapping tape and the battery cluster be located at the top of the corresponding battery cluster, which can achieve force balance at the upper and lower ends of the battery cluster, thereby further improving the horizontal and vertical limiting effect of the battery cluster. Specifically, the second strapping tape is arranged at intervals along the third and fourth directions of the battery rack, and the third and fourth directions are Figure 1 The length and width directions of the battery cluster are shown in FIG.

[0021] Preferably, it also includes a corner paper padding at the upper edge of the battery rack, and the second packing tape can be pressed tightly on the corner paper.

[0022] Placing corner paper at the contact position between the strapping tape and the battery cluster can prevent the strapping tape from being wrapped too tightly and leaving marks on the surface of the battery cluster, and also prevent the strapping tape from being cut at the corners of the battery cluster and causing damage to the strapping tape.

[0023] Preferably, a wrapping film is further included, wherein the wrapping film is wrapped around the outside of the battery rack and arranged along the third direction and the fourth direction.

[0024] Preferably, the wrapping film is wrapped at least three times around the positions of the battery rack corresponding to the first buffer, the second buffer, and the third buffer.

[0025] After the buffer is installed in the battery cluster, the battery cluster and the buffer can be packaged as a whole using a stretch film, which can fix the buffer in the battery cluster to prevent the buffer from falling off due to bumps during transportation, thereby causing shock absorption failure. Specifically, the battery cluster can be packaged in the third direction and the fourth direction (i.e. Figure 1 The buffer is wrapped around the battery rack (in the length and width directions of the battery cluster shown in the figure) and wrapped at least three times at the position where the buffer is passed, which can further improve the stability of the buffer installed in the battery cluster; that is, after the buffer is stuffed into the battery rack, the setting position of the buffer can be observed from the outside of the battery rack, and the wrapping film can be wrapped three times at the position where the buffer is located, in order to fully fix the buffer and prevent it from falling off from the battery rack.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention provides a battery cluster that is packaged as a whole and can be used to transport assembled battery clusters as a whole. By installing cushioning materials at multiple locations in the battery cluster, such as between adjacent battery packs, between the bottom of the battery pack and the battery rack, and on top of the battery rack, to provide shock absorption, damage to the battery packs, between the battery pack and the battery rack, and between the battery rack and other objects placed on it due to bumps during transportation can be avoided, thereby ensuring that the overall structure and various components of the battery cluster remain intact during transportation. In addition, by packaging and transporting the battery cluster as a whole, the present invention can save transportation space and store more battery clusters in the same volume of space; at the same time, it reduces the use of packaging materials and reduces packaging costs; after the battery cluster is transported as a whole to the destination, it can be used directly after unpacking, without the need to disassemble the package before transportation or reassemble it after transportation, thus reducing the installation process of the battery cluster, reducing installation costs, and improving packaging and transportation efficiency.

[0039] Example

[0040] This embodiment provides an integrally packaged battery cluster.

[0041] Figure 1 This is a schematic diagram of the packaging of the battery cluster (showing the battery pack) of the present invention; Figure 2 This is a schematic diagram of the packaging of the battery cluster (hidden battery pack) of the present invention; Figure 3 This is a schematic diagram of the overall packaging of the battery cluster of the present invention.

[0042] It should be noted that the orientation descriptions of the battery cluster relative to the overall package in this article, such as "top", "bottom", "above", "below", "upper", "lower", "horizontal", "vertical" and other orientation qualifiers, specifically refer to the relative orientation of the battery cluster in the horizontal state during packaging and transportation, which is different from the relative orientation of the battery cluster in the vertical state during use. This is hereby explained.

[0043] like Figures 1 to 3 As shown in , the integrally packaged battery cluster described in this embodiment may include a battery rack 11, a plurality of battery packs 12, a first buffer 2, a second buffer 3 and a third buffer 4. The plurality of battery packs 12 are installed in the battery rack 11, the first buffer 2 is installed between two adjacent battery packs 12, the second buffer 3 is installed between the battery rack 11 and the bottom of the battery pack 12, and the third buffer 4 is installed on the top of the battery rack 11.

[0044] Specifically, the battery rack 11 has a hollow structure, and the battery packs 12 can be installed in the hollow positions of the battery rack 11 to assemble a battery cluster 1. The battery cluster 1 is usually formed by assembling multiple battery packs 12 in the battery rack 11. The battery packs 12 and the battery rack 11 are not tightly fitted, and there are often multiple gaps. If the assembled battery cluster 1 is directly transported without taking any packaging and shock-absorbing measures, the battery cluster 1 will be affected by bumps and shaking during transportation. The battery packs 12 will move relative to the battery rack 11 and may collide and be damaged. Therefore, during the packaging process, it is necessary to use cushioning and shock-absorbing materials to fill the gaps in the battery cluster 1. The filling locations may mainly include the following locations:

[0045] ① The gaps between adjacent battery packs 12 in the battery rack 11 are filled with the first buffer 2 to separate the adjacent battery packs 12, thereby preventing the battery packs 12 from colliding with each other during transportation and generating lateral impact forces, thereby slowing down or even offsetting the vibration of the battery packs 12;

[0046] ② The gap between the bottom of the battery pack 12 and the battery rack 11 is filled with the second buffer 3 to separate the bottom of the battery pack 12 from the battery rack 11, thereby preventing the battery pack 12 and the battery rack 11 from colliding and generating vertical impact force during transportation;

[0047] ③ The top of the battery rack 11 is provided with a third buffer 4 to prevent the battery cluster 1 from colliding with other objects placed on top thereof during transportation and generating vertical impact force.

[0048] The first buffer 2, the second buffer 3 and the third buffer 4 used to fill the above-mentioned positions can all be pearl cotton, but the present invention is not limited to this. The positions that need to be filled in the battery cluster 1 are not limited to the above three positions. If there are other positions that need to be filled for shock absorption, they can also be filled; the material of the buffer used is not limited to pearl cotton, and other types of buffer materials can also be selected, such as plastic foam, etc. The first buffer 2, the second buffer 3 and the third buffer 4 can be the same or different materials, and the present invention does not make specific limitations on this.

[0049] Compared with the prior art method of splitting the battery cluster 1 into multiple modules for packaging and transportation, which results in low efficiency and the need to reassemble after transportation, the battery cluster of the utility model can be directly transported in an integrally packaged manner. By installing buffers between the battery packs 12 in the battery cluster 1, between the battery pack 12 and the battery rack 11, and at multiple positions outside the battery rack 11 for shock absorption, damage caused by collisions between the battery packs 12, between the battery pack 12 and the battery rack 11, and between the battery rack 11 and other external objects due to bumps during transportation can be avoided, thereby ensuring that the overall structure and various components of the battery cluster 1 remain intact during transportation. In addition, the utility model can save transportation space by packaging and transporting the battery cluster 1 as a whole, and more battery clusters 1 can be stored in a space of the same volume. At the same time, the use of packaging materials is reduced, thereby reducing packaging costs. After the battery cluster 1 is transported as a whole to the destination, it can be used directly after unpacking, without the need to disassemble the packaging before transportation or reassemble it after transportation. This reduces the installation process of the battery cluster 1, also reduces the installation cost, and improves packaging and transportation efficiency.

[0050] In this embodiment, the integrally packaged battery cluster of this embodiment may further include a battery cluster 1 along the third direction and the fourth direction (ie Figure 1A wrap film (not shown) is wrapped around the outside of the battery cluster 1 (in both the length and width directions of the battery cluster shown in the figure). The wrap film is wrapped at least three times around the corresponding locations of the buffers. After the buffers are inserted into the battery rack, their placement can be observed from the outside of the battery rack. The wrap film can be wrapped at least three times around the buffers to fully secure them and prevent them from falling out of the battery rack.

[0051] After the buffer is installed in the battery cluster 1, the battery cluster 1 and the buffer can be packaged as a whole using a stretch film, which can fix the buffer in the battery cluster 1 to prevent the buffer from falling off due to bumps during transportation, thereby causing shock absorption failure; specifically, the stretch film can be wrapped around the battery cluster 1 at least three times to ensure the stability of the wrapping and fixation; the stretch film can also be wrapped along the length direction or width direction or other arbitrary direction of the battery cluster 1, and can be multi-directional and multi-layer winding, as long as the battery cluster 1 containing the buffer can be guaranteed to have sufficient quality as a whole, and the present invention does not make specific restrictions on this.

[0052] In this embodiment, the integrally packaged battery cluster may further include a base plate 5 mounted at the lower end of the battery cluster 1 and a packaging box 7 covering the battery cluster 1. The base plate 5 and packaging box 7 may be fixedly connected. The battery cluster 1 may be fixed to the base plate 5, and the packaging box 7 may be used to cover the battery cluster 1, and the packaging box 7 may be fixedly connected to the base plate 5. Specifically, the base plate 5 may be a cardboard pallet, and the packaging box 7 may be a cardboard box. The cardboard pallet and the cardboard box may be installed in a coordinated manner to securely connect the two, thereby encapsulating the battery cluster 1 within. The cardboard box itself also has a certain cushioning effect, further protecting the battery cluster 1 within. However, the present invention is not limited to this. The base plate 5 and packaging box 7 may also be made of materials other than cardboard, such as wooden boxes, plastic boxes, etc., and the present invention does not impose specific limitations on this.

[0053] The bottom plate 5 can be a logistics plate or a turnover plate, etc., and a support leg 10 can be provided on both sides of the bottom plate 5 respectively. The support leg 10 can be used to support the upper bottom plate 5, packaging box 7, battery rack 11 and other components.

[0054] A packaging box 7 can be used to cover the assembled battery cluster 1 as a whole, forming an independent transportation space for a single battery cluster 1. In the scenario of transporting multiple battery clusters 1, sufficient spacing can be formed between adjacent battery clusters 1. The packaging boxes 7 also have a certain buffering effect, thereby avoiding collisions between the battery clusters 1 and causing damage.

[0055] Optionally, the integrally packaged battery cluster may further include a plurality of first strapping tapes 8 strapped to the exterior of the packaging box 7 and the base plate 5. These first strapping tapes 8 may be spaced apart along the length and width of the packaging box 7 and may be wrapped at least three times around the packaging box 7. The first strapping tapes 8 may be wrapped around the exterior of the packaging box 7 and the base plate 5 to secure the battery cluster 1. After the packaging box 7 is placed over the battery cluster 1, the strapping tape may be wrapped around the packaging box 7 and the base plate 5 to securely connect the packaging box 7 and the base plate 5, thereby securing the battery cluster 1 within the packaging box 7. Specifically, the first strapping tape 8 may be made of a plastic material such as polyethylene, polypropylene resin, nylon, polyester, or cold-rolled steel strip, effectively securing and sealing the packaging box 7. Alternatively, other methods such as adhesive tape and tying rope may be used to secure the packaging box 7 and the base plate 5, or self-tapping screws may be used to connect the packaging box 7 and the base plate 5. This is not specifically limited in the present invention.

[0056] In this embodiment, the integrally packaged battery cluster may further include a position-limiting assembly mounted on the base plate 5. The position-limiting assembly includes a plurality of position-limiting blocks 6 that abut the battery cluster and are arranged circumferentially around the battery cluster 1. The position-limiting assembly is mounted on the base plate 5 to limit the position of the battery cluster 1. During transportation, the battery cluster 1 may shift on the base plate 5 due to turbulence. To maintain relative stability between the battery cluster 1 and the base plate 5, a position-limiting assembly may be mounted on the base plate 5 to limit the position of the battery cluster 1. Preferably, the position-limiting assembly includes a plurality of position-limiting blocks 6 that abut the battery cluster 1. Specifically, the position-limiting assembly may include multiple position-limiting blocks 6. The position-limiting blocks 6 may be mounted at the bottom corners of the battery cluster 1, for example, at the four corners or in the middle of the sides of the battery cluster 1. The position-limiting blocks 6 abut the battery cluster 1 and are fixed to the base plate 5, thereby limiting lateral movement of the battery cluster 1 relative to the base plate 5 and maintaining relative stability between the battery cluster 1 and the base plate 5.

[0057] When installing the limit blocks 6, the battery cluster 1 can be placed at a suitable position on the base plate 5 first, and then multiple limit blocks 6 can be placed around the battery cluster 1 on the base plate 5, and the appropriate number, position and spacing can be selected, and each limit block 6 can be made to abut against the battery cluster 1, and then the limit blocks 6 can be fixed to the base plate 5 using tools such as self-tapping screws. The limit blocks 6 that are fixed and arranged around the battery cluster 1 can limit the battery cluster 1 to avoid lateral relative movement between the battery cluster 1 and the base plate 5 during transportation; here, the specific shape, size, number, setting position and mutual spacing of the limit blocks 6 can be arbitrarily selected according to actual packaging requirements, and the fixing method between the limit blocks 6 and the base plate 5 is not limited to self-tapping screw fixing, and can be adjusted arbitrarily. The present invention does not make specific restrictions on this.

[0058] The self-tapping screws can be wood screws or steel nails, etc., and the present invention does not make specific restrictions on this.

[0059] Optionally, in addition to the limit block 6 in the limit assembly, the limit block 6 can also be replaced by other components such as a limit rod, a limit ring, or a limit groove or other structure that can cooperate with the support legs of the battery cluster 1 is opened on the bottom plate 5. As long as the structure can achieve the fixing and limiting functions between the battery cluster 1 and the bottom plate 5, the present invention does not make specific restrictions on this.

[0060] In this embodiment, the integrally packaged battery cluster may further include a plurality of second strapping tapes 9 strapped outside the battery cluster 1 and the base plate 5. The plurality of second strapping tapes 9 correspond one-to-one to the plurality of limit blocks 6, and the plurality of second strapping tapes 9 may be strapped along the length and width directions of the battery cluster 1. The second strapping tape 9 is wrapped around the outside of the battery cluster 1 and the base plate 5 for fixation, and a corner paper (not shown in the figure) is used to protect the contact position between the battery cluster 1 and the second strapping tape 9. After the battery cluster 1 is placed on the base plate 5 and wrapped with a wrapping film for protection, the battery cluster 1 and the base plate 5 need to be wrapped together with the second strapping tape 9 to form a fixed whole to prevent accidents such as the battery cluster 1 falling off or tipping over from bumps during transportation. Corner paper is also placed at the contact position between the second strapping tape 9 and the battery cluster 1 to prevent the strapping tape from being wrapped too tightly and leaving marks on the surface of the battery cluster 1, and to prevent the strapping tape from being cut at the corners of the battery cluster 1 and causing damage.

[0061] Alternatively, the second strapping tape 9 may be a plastic strapping tape, such as polyethylene, polypropylene resin, nylon, polyester, or other materials, or cold-rolled steel strip, which can effectively bundle and seal the battery cluster 1 and the bottom plate 5. Alternatively, other tools such as adhesive tape and strapping rope may be used to securely bundle the battery cluster 1 and the bottom plate 5. Materials other than corner paper, such as pearl cotton or foam, may also be used between the second strapping tape 9 and the battery cluster 1 for protection. This is not specifically limited in the present invention.

[0062] It should be noted that the above-mentioned operating steps should be performed in the following order according to actual operation: the buffer materials are loaded into the designated positions in the battery cluster 1, the battery cluster 1 is then wrapped with a stretch film, the battery cluster 1 is placed on the bottom plate 5, the limit blocks 6 are installed on the bottom plate 5 to limit the battery cluster 1, corner paper is placed on the top and side corners of the battery cluster 1, and the second strapping tape 9 is used to pack and fix the battery cluster 1 and the bottom plate 5, and the packaging box 7 is covered on the outside of the battery cluster 1 and installed on the bottom plate 5, and the first strapping tape 8 is used to bundle the packaging box 7 so that it is fixedly connected to the bottom plate 5 to form a whole package.

[0063] After the packing box 7 is installed, the carton legs can be fixed to the bottom of the packing box 7 with a nail gun. The number of legs can usually be 4, which can be installed at the four corners of the packing box 7 respectively; but the present invention is not limited to this. The number and fixing method of the legs can be selected according to needs, and the present invention does not make specific limitations on this.

[0064] In summary, the present invention provides a battery cluster that is packaged as a whole and can be used to transport assembled battery clusters as a whole. By installing cushioning materials at multiple locations in the battery cluster, such as between adjacent battery packs, between the bottom of the battery pack and the battery rack, and on top of the battery rack, to reduce shock, damage caused by collisions between battery packs, between battery packs and the battery rack, and between the battery rack and other objects placed on top of it during transportation can be avoided, thereby ensuring that the overall structure and various components of the battery cluster remain intact during transportation. In addition, the present invention can save transportation space by packaging the battery cluster as a whole and can store more battery clusters in the same volume of space; at the same time, it reduces the use of packaging materials and reduces packaging costs; after the battery cluster is transported as a whole to the destination, it can be used directly after unpacking, without the need to disassemble the package before transportation or reassemble it after transportation, thus reducing the installation process of the battery cluster, reducing installation costs, and improving packaging and transportation efficiency.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
