Description

Technical Field

[0001] This utility model belongs to the technical field of zinc-air battery power banks, and specifically relates to a fixing structure for a charging cable of a soft-pack zinc-air battery power bank. Background Technology

[0002] A zinc-air battery power bank is a charging device that uses zinc-air batteries as an energy source. Zinc-air batteries are a hybrid of rechargeable and fuel cell technology, characterized by low cost, high energy output, and high safety. Their working principle involves using oxygen from the air as the positive electrode active material and metallic zinc as the negative electrode active material, generating electrical energy through an electrochemical reaction. The advantages of zinc-air batteries include high energy density, environmental friendliness, and high safety performance.

[0003] Currently, using non-woven fabrics and other materials as the outer shell of zinc-air battery power banks offers the best cost performance. However, the edge sealing of zinc-air battery power banks with non-woven fabrics is different from other products. During the sealing process, the zinc-air battery power bank cannot be completely wrapped, and the charging cable must be exposed.

[0004] This presents two problems. First, since most of the charging cable ends are cylindrical, when the zinc-air battery power bank is wrapped in non-woven fabric, other parts of the product need to be flat-pressed and heat-sealed. However, when the non-woven fabric is flat-pressed together with the charging cable, the non-woven fabric around the cable cannot be heat-shrinked and pressed to cover the cable, causing problems such as the charging cable exit point being easy to fall off and poor sealing. If molding is used, it is difficult to accurately fix the cylindrical cable ends in the mold during automated production.

[0005] Secondly, in automated production, the edge sealing process often uses a method of hot pressing followed by cutting to make the edges neat. However, when packaging zinc-air battery power banks with non-woven fabric, the charging cable area cannot be cut, and how to make the edge at that location neat is a major challenge.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a fixing structure for a soft-pack zinc-air battery power bank charging cable, including non-woven fabric, a battery cell unit, and a transmission structure. The transmission structure is connected to the battery cell unit. The non-woven fabric is folded and then hot-pressed to wrap the battery cell unit inside. A first double-sided adhesive tape is provided between the transmission structure and the non-woven fabric to fix the transmission structure to the non-woven fabric.

[0008] The transmission structure includes a charging head and an insulating conduit. One end of the insulating conduit is fixed to the charging head, and the charging head is connected to two transmission lines. Both transmission lines are connected to the battery cell unit, and both transmission lines are housed inside the insulating conduit.

[0009] A notch is opened on one side of the non-woven fabric before it is folded over, and the insulating conduit is located at the notch.

[0010] When the non-woven fabric is folded, one end of the insulating tube will adhere to the inside of the first double-sided tape, and the outside of the first double-sided tape will adhere to the non-woven fabric.

[0011] The battery cell unit includes battery cell group one, battery cell group two, battery cell group three, and battery cell group four, and each of them is provided with an air positive electrode surface.

[0012] Cell group one and cell group two are arranged in an overlapping manner, and the air positive electrode surfaces of both cell group one and cell group two after the overlap are in contact with the inner wall of the non-woven fabric. Cell group three and cell group two are arranged in an overlapping manner, and the air positive electrode surfaces of both cell group three and cell group four after the overlap are in contact with the inner wall of the non-woven fabric.

[0013] A second double-sided tape is provided between cell group one and cell group three, and a second double-sided tape is also provided between cell group three and cell group four.

[0014] The negative terminal of cell group one is connected in series with the positive terminal of cell group three, the negative terminal of cell group three is connected in series with the positive terminal of cell group four, and the negative terminal of cell group four is connected in series with the positive terminal of cell group two, so that all four cell groups are connected in series.

[0015] The positive terminal of cell group one is connected to a transmission line, and the negative terminal of cell group two is connected to another transmission line.

[0016] Non-woven fabrics are breathable.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model uses a combination of adhesive bonding and hot pressing to form an arc-shaped wrap around the charging cable, and the edges of the power bank are firmly hot-pressed, thus solving the edge sealing problem of zinc-air battery power banks.

[0019] 2. This utility model uses a combination of pre-reserved notches and cutting to ensure that the edges of the power bank are neatly cut.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-2 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0025] Please see Figure 1 As shown:

[0026] This embodiment provides a fixing structure for a charging cable of a soft-pack zinc-air battery power bank, including a non-woven fabric 1, a battery cell unit 2, and a transmission structure 3. The transmission structure 3 is connected to the battery cell unit 2. The non-woven fabric 1 is folded and then hot-pressed to wrap the battery cell unit 2 inside. A first double-sided adhesive tape 5 is provided between the transmission structure 3 and the non-woven fabric 1. The first double-sided adhesive tape 5 is used to fix the transmission structure 3 and the non-woven fabric 1.

[0027] A notch 4 is provided on one side of the non-woven fabric 1, the insulating conduit 7 is located at the notch 4, and the first double-sided adhesive tape 5 is attached to the notch 4.

[0028] During production, a notch 4 is first cut into the non-woven fabric. Double-sided tape is then applied to the edge of the notch 4. The release paper is removed, and the battery cell 2 is placed on the non-woven fabric 1. The non-woven fabric 1 is then folded over to wrap the battery cell 2. Since the transmission structure 3 is located at the notch 4, the first double-sided tape 5 plays a crucial role during the wrapping process. One side of the tape is tightly adhered to the surface of the transmission structure 3, and the other side is adhered to the non-woven fabric 1. The adhesiveness of the tape is used to initially fix the transmission structure 3 to the non-woven fabric 1, solving the problem that the non-woven fabric 1 itself is not adhesive and it is difficult to fix the charging cable.

[0029] Next, a hot pressing process is carried out. During the hot pressing process, the non-woven fabric in the area of ​​the notch 4 is avoided. After the hot pressing is completed, the hot pressing position 15 is cut. After cutting, the cut edge on one side of the transmission structure 3 will be flush with the position of the notch 4, so that the edges are neat and tidy. This will result in a zinc-air battery power bank product with beautiful and neat edges.

[0030] like Figure 1-2As shown, the transmission structure 3 includes a charging head 6 and an insulating conduit 7. One end of the insulating conduit 7 is fixed to the charging head 6. The charging head 6 is connected to two transmission lines 8, both of which are connected to the battery cell unit 2. Both transmission lines 8 are housed inside the insulating conduit 7. Users can insert the charging head 6 into the device to be charged to transfer the electrical energy of the battery cell unit 2 to the device through the transmission lines 8 and the charging head 6 for charging. The insulating conduit 7 is used to prevent the transmission lines 8 from being exposed to the outside, thus preventing damage to the transmission lines 8 and improving safety.

[0031] After the non-woven fabric 1 is folded and hot-pressed, one end of the insulating tube 7 will adhere to the inner side of the first double-sided tape 5, and the outer side of the first double-sided tape 5 will adhere to the non-woven fabric 1 to fix and position the insulating tube and the non-woven fabric.

[0032] like Figure 1-2 As shown, the battery cell unit 2 includes a first battery cell group 9, a second battery cell group 10, a third battery cell group 11, and a fourth battery cell group 12, each of which is provided with an air positive electrode surface 13. The first battery cell group 9 and the second battery cell group 10 are arranged in an overlapping manner, and the air positive electrode surfaces 13 of the overlapping first battery cell group 9 and the second battery cell group 10 are in contact with the inner wall of the non-woven fabric 1. The third battery cell group 11 and the second battery cell group 10 are arranged in an overlapping manner, and the air positive electrode surfaces 13 of the overlapping third battery cell group 11 and the fourth battery cell group 12 are in contact with the inner wall of the non-woven fabric 1. The non-woven fabric 1 itself has a breathable function. Therefore, by overlapping the battery cells, the volume can be greatly reduced and the practicality can be improved while ensuring the number of battery cells and not affecting the contact between the air positive electrode surface 13 of each battery cell group and the air.

[0033] like Figure 2 As shown, a second double-sided tape 14 is provided between cell group 19 and cell group 31, and a second double-sided tape 14 is also provided between cell group 31 and cell group 412 to form interlayer bonding, enhance the stability of the stacked structure, and improve the fixing effect between cell groups.

[0034] like Figure 2 As shown, the negative terminal of cell group 19 is connected in series with the positive terminal of cell group 31, the negative terminal of cell group 31 is connected in series with the positive terminal of cell group 412, the negative terminal of cell group 412 is connected in series with the positive terminal of cell group 210, the positive terminal of cell group 19 is connected to one transmission line 8, and the negative terminal of cell group 210 is connected to another transmission line 8. Thus, the four cell groups are connected in series with two transmission lines 8. By connecting the device to be charged to the charging head 6, the power of the four cell groups can be transferred to the device to be charged for charging.

[0035] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
