[0035] The following describes in detail the overall structure, working principle, and technical effects of the packaging structure 10 provided by this utility model through embodiments and in conjunction with the accompanying drawings.

[0036] Please refer to Figure 1 and Figure 2 The packaging structure 10 provided by this utility model is used for packaging one or more battery cells.

[0037] Please refer to Figure 1 and Figure 2 This utility model provides a packaging structure 10, comprising:

[0038] Foam board 100, the foam board 100 is provided with a first receiving groove 110;

[0039] The blister tray 200 includes an integral plate 210 and a surrounding plate 220. The plate 210 is located on the side of the foam board 100 where the first receiving groove 110 is provided. The plate 210 is provided with a mounting part 230 for receiving products. The mounting part 230 is provided in the first receiving groove 110. The surrounding plate 220 is provided along the outer edge of the plate 210 and faces the foam board 100 so that the surrounding plate 220 covers the corners and outer walls of the foam board 100.

[0040] It should be noted that the product in this application is a single battery cell, and the packaging structure 10 provided in this application is not limited to the field of battery packaging, but can also be used in product packaging in other fields.

[0041] Understandably, when packaging the battery cell, the blister tray 200 is first assembled onto the foam board 100, so that the mounting part 230 of the blister tray 200 is correspondingly assembled into the first receiving groove 110 of the foam board 100, and the surrounding plate 220 covers the corners and outer wall of the foam board 100; then the top of the battery cell is oriented towards the mounting part 230, and the battery cell is housed in the mounting part 230. This application incorporates a blister tray 200, an integral board 210, and a surrounding panel 220. The surrounding panel 220 wraps around the edges and outer walls of the foam board 100. On one hand, this prevents the foam board 100 from being damaged by external factors during handling, thus avoiding impacts on shipment and reducing rework rates. On the other hand, the method of wrapping the foam board 100 with the blister tray 200 eliminates the need for fixing the blister tray 200 and the foam board 100 with plastic nails or glue, reducing production costs and improving packaging efficiency.

[0042] In this embodiment, the packaging structure 10 further includes an annular elastic strap 300.

[0043] Please refer to Figure 2 An annular elastic strap 300 is disposed on the outside of the enclosure 220 and is used to fix the enclosure 220 to the outer wall of the foam board 100.

[0044] Understandably, when the blister tray 200 is assembled onto the foam board 100, the surrounding panel 220 covers the corners and outer wall of the foam board 100, and the annular elastic strap 300 is fitted over the outside of the surrounding panel 220, the annular elastic strap 300 fixes the surrounding panel 220 and the blister tray 200 onto the foam board 100, so that the connection between the blister tray 200 and the foam board 100 is stable.

[0045] When the annular elastic strap 300 is sleeved on the enclosure 220 and the foam board 100, the annular elastic strap 300 compresses the foam board 100, and the foam board 100 attempts to restore its original shape and generates a rebound force; thereby, under the action of the annular elastic strap 300 and the foam board 100, the enclosure 220 of the blister tray 200 is stably fixed on the foam board 100.

[0046] Optionally, the annular elastic strap 300 includes an annular compression strap capable of generating a clamping force.

[0047] It is understandable that the width of the annular compression belt is 6-8mm and the compression rate is 30%, which allows the annular compression belt to compress the foam board 100, causing the foam board 100 to generate a compressive force of ≥5N / cm2, i.e. the aforementioned rebound force.

[0048] Of course, the width and compression ratio of the annular compression belt can be set according to the actual size of the foam board 100.

[0049] Optionally, the annular elastic band 300 includes an annular elastic band with elasticity.

[0050] Of course, in some alternative embodiments, in order to ensure the stable connection between the blister tray 200 and the foam board 100, the blister tray 200 and the foam board 100 can also be fixed by means of plastic nails, glue, etc.

[0051] In this embodiment, the packaging structure 10 includes a blister tray 200.

[0052] The blister tray 200 is used to isolate the battery cell and the foam board 100, which can prevent the powder falling from the foam board 100 from soiling the battery cell.

[0053] In this embodiment, please refer to Figure 1 and Figure 2 The blister tray 200 includes an integral plate 210 and a surrounding plate 220. The plate 210 is located on the side of the foam board 100 where the first receiving groove 110 is provided. The plate 210 is provided with a mounting part 230 for receiving products. The mounting part 230 is provided in the first receiving groove 110. The surrounding plate 220 is provided along the outer edge of the plate 210 and faces the foam board 100 so that the surrounding plate 220 covers the corners and outer walls of the foam board 100.

[0054] In this embodiment, please refer to Figure 1 and Figure 2 The blister tray 200 includes a plate 210, which is a flat plate structure. An installation portion 230 extends from one end of the plate 210 toward the foam board 100. The plate 210 is provided with a plurality of installation portions 230. Along the length direction and / or width direction of the plate 210, the plurality of installation portions 230 are arranged sequentially at intervals so that the plurality of installation portions 230 are arranged in a matrix.

[0055] In this embodiment, please refer to Figures 1-3 The installation section 230 is provided with a second receiving slot 231 for accommodating products; please refer to Figure 4 The bottom wall of the second receiving groove 231 is provided with a positive electrode mounting part 240, an explosion-proof valve mounting part 250 and a negative electrode mounting part 260 arranged at intervals in sequence. The positive electrode mounting part 240 is provided with a positive electrode mounting groove 241; the explosion-proof valve mounting part 250 is provided with an explosion-proof valve mounting groove 251, and the negative electrode mounting part 260 is provided with a negative electrode mounting groove 261.

[0056] The positive electrode mounting part 240 is provided with a positive electrode mounting groove 241; the positive electrode mounting groove 241 is used to set the positive electrode post of the battery cell.

[0057] The explosion-proof valve mounting section 250 is provided with an explosion-proof valve mounting groove 251; the explosion-proof valve mounting groove 251 is used to install the explosion-proof valve of the battery cell.

[0058] The negative electrode mounting part 260 is provided with a negative electrode mounting groove 261; the negative electrode mounting groove 261 is used to set the negative electrode of the battery cell.

[0059] Understandably, the positive electrode mounting slot 241, the explosion-proof valve mounting slot 251, and the negative electrode mounting slot 261 can further adapt and install the positive electrode, negative electrode, and explosion-proof valve of the battery cell, thereby further improving the installation stability of the battery cell during transportation. At the same time, the mounting part 230 can protect the positive electrode, negative electrode, and explosion-proof valve, separating the positive electrode, negative electrode, and explosion-proof valve from the foam board 100, ensuring the cleanliness of the battery cell, and also avoiding interference or wear to the electrode and explosion-proof valve during transportation.

[0060] In this embodiment, please refer to Figure 3 and Figure 6 The explosion-proof valve mounting part 250 has protrusions 270 on its two opposite outer side walls, and grooves 114 are provided on the two opposite side walls of the explosion-proof valve mating groove 112 of the foam board. The protrusions 270 are elastically engaged in the grooves 114.

[0061] Optionally, the length of the bottom edge of the protrusion 270 is greater than the length of the top edge; for example, the protrusion 270 can be a trapezoidal structure. Understandably, this arrangement allows the protrusion 270 to engage within the groove 114, further securing and limiting the blister tray 200 and the foam board 100, thus ensuring a stable connection between the two.

[0062] It is understandable that, since the explosion-proof valve mounting part 250 is provided with an explosion-proof valve mounting groove 251, the explosion-proof valve mounting part 250 has a thin-walled structure. When the explosion-proof valve mounting part 250 is connected to the explosion-proof valve mating groove 112 of the foam board 100, the explosion-proof valve mounting part 250 undergoes elastic deformation until the bottom of the explosion-proof valve mounting part 250 contacts the bottom wall of the explosion-proof valve mating groove 112. At this point, the explosion-proof valve mounting part 250 resets and the protrusion 270 is elastically engaged in the groove 114.

[0063] In this embodiment, please refer to Figure 4 The blister tray 200 includes a surrounding panel 220, which extends outward from the outer edge of the panel 210 toward the foam board 100. The length of the surrounding panel 220 is adjustable along the thickness direction of the foam board 100, and the surrounding panel 220 can cover part of the side wall and all of the side wall of the foam board 100.

[0064] In this embodiment, the blister tray 200 is made of PP (polypropylene), which has the characteristics of chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good wear resistance processing performance. Of course, in other embodiments, the blister tray 200 can also be made of other materials such as PC (polycarbonate), PVC (polyvinyl chloride) or nylon.

[0065] In this embodiment, the packaging structure 10 includes a foam board 100.

[0066] Among them, foam board 100 is used to protect the battery cell during transportation.

[0067] In this embodiment, please refer to Figure 2 Along the thickness direction of the foam board 100, a first receiving groove 110 is provided on the top of the foam board 100; wherein, a plurality of first receiving grooves 110 are provided on the foam board 100; along the length direction and / or width direction of the foam board 100, the plurality of first receiving grooves 110 are arranged sequentially at intervals.

[0068] In this embodiment, please refer to Figure 2 The bottom wall of the first receiving groove 110 is provided with a positive electrode mating groove 111, an explosion-proof valve mating groove 112 and a negative electrode mating groove 113 arranged in sequence at intervals.

[0069] Please refer to Figure 5 The positive electrode mounting slot 241 is configured to cooperate with the positive electrode mating slot 111, the negative electrode mounting slot 261 is configured to cooperate with the negative electrode mating slot 113, and the explosion-proof valve mounting slot 251 is configured to cooperate with the explosion-proof valve mating slot 112.

[0070] In this embodiment, a first receiving groove 110 is provided at one end of the foam board 100 along its thickness direction, and a third receiving groove is provided at the other end of the foam board 100. The third receiving groove includes multiple third receiving grooves, with each of the multiple first receiving grooves 110 corresponding to one of the multiple third receiving grooves. That is, the arrangement of the multiple first receiving grooves 110 is the same as the arrangement of the multiple third receiving grooves, ensuring that the arrangement of each layer of battery cells after packaging is identical.

[0071] Understandably, the first receiving slot 110 is located at the top of the foam board 100, and the top of the first group of battery cells can be installed in the first receiving slot 110; the third receiving slot is located at the bottom of the foam board 100, and the bottom of the second group of battery cells can be installed in the third receiving slot. With this configuration, by manufacturing a packaging structure 10, it is possible to stack and package multiple groups and layers of battery cells, saving costs and improving packaging efficiency.

[0072] In this embodiment, the foam board 100 is made of GPO (expandable polystyrene bead), which has the characteristics of high temperature resistance, moisture resistance, impact resistance and stable insulation performance. In addition, GPO does not contain calcium, so there is no accumulation of calcium in the top patch of the battery cell, which would cause the top patch to become dirty and improve the cleanliness of the top of the battery cell.

[0073] Of course, in other embodiments, the foam board 100 may also be made of EPO (polymer emulsion), which does not contain calcium; or the foam board 100 may also be made of other foaming materials such as EPS (polystyrene foam), EPE (polyethylene foam) or EPP (polypropylene foam).

[0074] The working principle and process of the packaging structure 10 provided in this embodiment of the present invention are as follows: When packaging the battery cell, the blister tray 200 is first assembled onto the foam board 100, so that the mounting part 230 of the blister tray 200 is correspondingly assembled into the first receiving groove 110 of the foam board 100, and the surrounding plate 220 is wrapped around the corners and outer wall of the foam board 100; the annular elastic strap 300 is sleeved on the outside of the surrounding plate 220, so that under the action of the annular elastic strap 300 and the foam board 100, the surrounding plate 220 of the blister tray 200 is stably fixed on the foam board 100.

[0075] In summary, the packaging structure 10 provided in this embodiment of the present invention, by setting up a blister tray 200, an integral plate 210 and a surrounding plate 220, with the surrounding plate 220 wrapping the corners and outer walls of the foam board 100, can, on the one hand, prevent the foam board 100 from being bumped and powdered due to external factors during handling, thus avoiding affecting shipment and reducing rework rate; on the other hand, the way the blister tray 200 wraps around the foam board 100 eliminates the need for fixing the blister tray 200 and the foam board 100 with plastic nails, glue, etc., reducing production costs and improving packaging efficiency.

[0076] Furthermore, by setting an annular elastic strap 300, when the annular elastic strap 300 is sleeved on the enclosure 220 and the foam board 100, the annular elastic strap 300 compresses the foam board 100, and the foam board 100 attempts to restore its original shape and generates a rebound force; thereby, under the action of the annular elastic strap 300 and the foam board 100, the enclosure 220 of the blister tray 200 is stably fixed on the foam board 100.

[0077] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
