Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically, to a waterproof structure and a battery device having the same. Background Technology

[0002] Currently, the waterproof performance of a battery pack directly affects its lifespan, safety level, and many other properties. Therefore, battery packs that have just been manufactured typically require additional waterproofing treatment.

[0003] In existing technology, workers usually use heat shrink tubing to initially seal the battery pack, and use adhesive to bond waterproof foam at both ends (through holes) of the heat shrink tubing to seal the gap between the through hole edge and the battery pack.

[0004] However, current waterproofing technologies heavily rely on the material of the waterproof foam, the adhesive strength of the backing, and the bonding experience of the installers. The overall waterproofing effect is increasingly insufficient to meet the waterproofing requirements of battery packs. Furthermore, the adhesive is prone to aging and weakening of its bonding strength, leading to inadequate waterproofing performance and significant safety hazards after long-term use. Additionally, ensuring a smooth, wrinkle-free application of the waterproof foam during installation is time-consuming and labor-intensive. Utility Model Content

[0005] The main objective of this invention is to provide a waterproof structure and a battery device having the same, in order to solve the problem of poor waterproof reliability of existing battery pack waterproof structures.

[0006] To achieve the above objectives, according to one aspect of the present invention, a waterproof structure is provided, comprising: a heat-shrinkable member having a receiving cavity and a through hole communicating with the receiving cavity, the through hole being used for installing a battery module into the receiving cavity, the heat-shrinkable member covering the outer surface of the battery module after being heated and shrunk; a cover being disposed at the through hole and having an annular receiving recess, at least a portion of the opening of the annular receiving recess being disposed opposite to the heat-shrinkable member, such that the inner wall of the annular receiving recess and the heat-shrinkable member surround to form a first annular receiving cavity; or, such that the inner wall of the annular receiving recess and the heat-shrinkable member and the battery module surround to form a first annular receiving cavity, the first annular receiving cavity being used to receive a sealing adhesive.

[0007] Furthermore, the cover includes a covering portion and a surrounding portion disposed on the covering portion, with a covering recess formed between the covering portion and the surrounding portion, and one end of the heat shrinkable member having a through hole located within the covering recess.

[0008] Furthermore, there is a preset gap between the enclosure portion and the outer peripheral surface of the heat shrinkable member, so that the enclosure portion and the heat shrinkable member surround to form a second annular receiving cavity, which is used to receive the sealing adhesive.

[0009] Furthermore, an annular receiving recess is provided on the surface of the cover portion facing the heat shrink member; wherein, there is one annular receiving recess, and the annular receiving recess extends to the side of the cover portion so that the first annular receiving cavity and the second annular receiving cavity are connected.

[0010] Furthermore, the inner wall of the annular receiving recess is an inclined surface, which is positioned opposite to the heat shrinkable component and / or battery module.

[0011] Furthermore, an annular receiving recess is provided on the surface of the cover portion facing the heat shrink member; wherein, there are multiple annular receiving recesses, and the multiple annular receiving recesses are arranged at radial intervals along the cover portion, and the opening of at least one annular receiving recess is located outside the through hole.

[0012] Furthermore, the heat shrinkable part is tubular and forms two through holes, and there are two covers, which are respectively placed over the two through holes.

[0013] Furthermore, at least one cover is provided with a through hole, which is spaced apart from the annular receiving recess and communicates with the through hole. The through hole and the through hole are used for the wires of the battery module to pass through. The wall of the through hole and the end face of the battery module covered with the heat shrinkable component form a receiving groove for receiving the sealing adhesive.

[0014] Furthermore, at least part of the cover is made of a transparent material.

[0015] According to another aspect of the present invention, a battery device is provided, the battery device including a battery module and a waterproof structure, wherein at least a portion of the battery module is located in a receiving cavity of the waterproof structure; wherein the waterproof structure is the aforementioned waterproof structure.

[0016] Applying the technical solution of this utility model, the heat shrinkable component of the waterproof structure has a receiving cavity and a through hole communicating with the receiving cavity. The through hole is used for installing the battery module into the receiving cavity. After being heated and shrunk, the heat shrinkable component covers the outer surface of the battery module. The cover is placed on the through hole and has an annular receiving recess. At least a portion of the opening of the annular receiving recess is arranged opposite to the heat shrinkable component, so that the inner wall of the annular receiving recess and the heat shrinkable component surround to form a first annular receiving cavity; or, so that the inner wall of the annular receiving recess and the heat shrinkable component and the battery module surround to form a first annular receiving cavity. The first annular receiving cavity is used to receive the sealing adhesive. In this way, after the worker places the battery module into the receiving cavity and heats the heat-shrinkable component to cover the battery module, a sealant with a certain amount of excess (slightly overflowing the annular receiving recess) can be applied to the annular receiving recess of the cover. Then, the cover is placed on the through hole. Since at least part of the opening of the annular receiving recess is positioned opposite the heat-shrinkable component, the through hole is located entirely within the inner ring of the first annular receiving cavity. That is, the sealant in the first annular receiving cavity forms a sealing area between the cover and the heat-shrinkable component, reliably sealing the through hole. This solves the problem of poor waterproof reliability in existing battery pack waterproof structures. Furthermore, the worker only needs to apply the sealant and place the cover to complete the sealing operation, making the entire process very simple and quick. There is no need to worry about wrinkles in the waterproof foam, which not only improves the worker's work efficiency but also enhances the overall aesthetic appearance of the battery device.

[0032] To address the issue of poor waterproof reliability in existing battery pack waterproof structures, this application provides a waterproof structure and a battery device having the same.

[0033] like Figures 1 to 6As shown, the waterproof structure includes a heat-shrinkable component 10 and a cover 20. The heat-shrinkable component 10 has a receiving cavity and a through hole 11 communicating with the receiving cavity. The through hole 11 is used for installing the battery module 1 into the receiving cavity. After being heated and shrunk, the heat-shrinkable component 10 covers the outer surface of the battery module 1. The cover 20 is disposed over the through hole 11 and has an annular receiving recess 21. At least a portion of the opening of the annular receiving recess 21 is disposed opposite to the heat-shrinkable component 10, so that the inner wall of the annular receiving recess 21 and the heat-shrinkable component 10 surround each other to form a first annular receiving cavity 30; or, the inner wall of the annular receiving recess 21 and the heat-shrinkable component 10 and the battery module 1 surround each other to form a first annular receiving cavity 30. The first annular receiving cavity 30 is used to receive a sealing adhesive.

[0034] Applying the technical solution of this embodiment, the heat-shrinkable component 10 of the waterproof structure has a receiving cavity and a through hole 11 communicating with the receiving cavity. The through hole 11 is used for the battery module 1 to be installed into the receiving cavity. After being heated and shrunk, the heat-shrinkable component 10 covers the outer surface of the battery module 1. The cover 20 is provided at the through hole 11 and has an annular receiving recess 21. At least a portion of the opening of the annular receiving recess 21 is disposed opposite to the heat-shrinkable component 10, so that the inner wall of the annular receiving recess 21 and the heat-shrinkable component 10 surround each other to form a first annular receiving cavity 30; or, the inner wall of the annular receiving recess 21 and the heat-shrinkable component 10 and the battery module 1 surround each other to form a first annular receiving cavity 30. The first annular receiving cavity 30 is used to receive the sealing adhesive. In this way, after the worker places the battery module 1 into the receiving cavity and heats the heat shrinkable component 10 to cover the battery module 1, a sealant with a certain amount of redundancy (slightly overflowing the annular receiving recess 21) can be applied to the annular receiving recess 21 of the cover 20. Then, the cover 20 is placed over the through hole 11. Since at least part of the opening of the annular receiving recess 21 is opposite to the heat shrinkable component 10, the through hole 11 is located entirely within the inner ring of the first annular receiving cavity 30. That is, the sealant in the first annular receiving cavity 30 forms a sealing area between the cover 20 and the heat shrinkable component 10, thus reliably sealing the through hole 11. This solves the problem of poor waterproof reliability of the existing battery pack waterproof structure. At the same time, the worker only needs to apply the sealant and place the cover 20 to complete the sealing operation. The overall operation is very simple and quick, and there is no need to worry about wrinkles in the waterproof foam. This not only improves the worker's work efficiency but also enhances the overall aesthetic appearance of the battery device.

[0035] In this embodiment, the sealant is a one-component room temperature vulcanizing adhesive.

[0036] Optionally, the sealant is a sealing adhesive.

[0037] In this embodiment, the battery module 1 has a cuboid structure, and the heat shrinkable part 10 is heat-shrinked and wrapped around the battery module 1 to form a corresponding structure.

[0038] In this embodiment, the opening of the annular receiving recess 21 is disposed opposite to the heat shrink member 10, and the opening of the annular receiving recess 21 is located entirely outside the through hole 11. In fact, the opening of the annular receiving recess 21 can also be partially disposed opposite to the heat shrink member 10 and partially disposed opposite to the battery module 1, that is, the edge of the through hole 11 is located inside the opening of the annular receiving recess 21, so that the sealing adhesive can flow into the space between the heat shrink member 10 and the battery module 1.

[0039] like Figures 1 to 3 As shown, the cover 20 includes a covering portion 22 and a surrounding portion 23 disposed on the covering portion 22. A covering recess 24 is formed between the covering portion 22 and the surrounding portion 23. One end of the heat shrinkable component 10 with a through hole 11 is located within the covering recess 24. In this way, the above-mentioned arrangement further reduces the difficulty of operation for workers (i.e., workers only need to fasten the cover to the end of the heat shrinkable component 10 without having to consider the position), while also enabling the cover 20 to have a certain protective function. That is, the cover 20 can protect the corners of the heat shrinkable component 10 (battery module 1) to avoid collisions and damage to the corners with low structural strength, thereby improving the overall protective performance of the battery device.

[0040] In this embodiment, the covering part 22 is a rectangular plate structure, and the surrounding part 23 is a rectangular ring structure formed by connecting multiple plate segments in sequence. The rectangular ring structure is set on the plate surface of the rectangular plate structure to form the cover 20 (covering recess 24).

[0041] Specifically, the cover 20 is a blister pack.

[0042] Optionally, a predetermined gap is provided between the enclosure portion 23 and the outer peripheral surface of the heat shrinkable member 10, so that a second annular receiving cavity 40 is formed between the enclosure portion 23 and the heat shrinkable member 10. The second annular receiving cavity 40 is used to receive the sealing adhesive. In this way, a double seal is formed between the sealing adhesive in the second annular receiving cavity 40 and the sealing adhesive in the first annular receiving cavity 30, so as to further improve the waterproof reliability of the waterproof structure.

[0043] Optionally, an annular receiving recess 21 is provided on the surface of the cover portion 22 facing the heat-shrinkable member 10. There is one annular receiving recess 21, which extends to the side of the cover portion 22 to connect the first annular receiving cavity 30 and the second annular receiving cavity 40. This arrangement allows the sealant to flow between the first annular receiving cavity 30 and the second annular receiving cavity 40, improving the filling reliability of the sealant in both cavities and thus enhancing the sealing reliability of the cover 20.

[0044] Specifically, during the actual application of the sealant, it is inevitable that too much or too little sealant will be applied (too little is usually rare, as workers tend to apply too much unconsciously). When too much sealant is applied, the sealant in the first annular receiving cavity 30 and the second annular receiving cavity 40 will continuously flow as the worker presses down on the cover 20, and will flow to the outside of the cover 20 through the second annular receiving cavity 40 (the preset gap between the enclosure 23 and the outer peripheral surface of the heat shrinkable component 10), ensuring that the cover 22 can fit tightly with the heat shrinkable component 10 and the battery module 1, thereby improving the sealing reliability of the cover 20. When too little sealant is applied, the sealant in the first annular receiving cavity 30 and the second annular receiving cavity 40 can also complement each other, further improving the sealing reliability of the cover 20.

[0045] Optionally, the inner wall of the annular receiving recess 21 is an inclined surface 211, which is positioned opposite to the heat shrinkable component 10 and / or the battery module 1. In this way, when the operator presses down on the cover 20, the inclined surface 211 can guide the flow of the sealant, allowing it to flow into the area between the surface of the cover 20 without the annular receiving recess 21 and the heat shrinkable component 10, further increasing the sealing range of the sealant and improving the sealing reliability of the cover 20.

[0046] In other embodiments not shown in the accompanying drawings, an annular receiving recess 21 is provided on the surface of the cover portion 22 facing the heat-shrinkable member 10. Multiple annular receiving recesses 21 are provided, spaced radially apart along the cover portion 22, with the opening of at least one annular receiving recess 21 located outside the through hole 11. In this way, multiple annular receiving recesses 21 can form multiple first annular receiving cavities 30, enabling the first annular receiving cavities 30 to form multiple seals. This improves the sealing reliability of the cover 20 and also allows for greater flexibility and variety in the number of annular receiving recesses 21, adapting to different working conditions and usage requirements, and enhancing the processing flexibility of the operator.

[0047] like Figure 1As shown, the heat shrinkable component 10 is tubular and forms two through holes 11. There are two covers 20, each covering one of the two through holes 11. Thus, the heat shrinkable component 10 is essentially a heat shrink tubing, thereby reducing the processing cost and difficulty for workers. Simultaneously, the aforementioned arrangement of the covers 20 enables simultaneous sealing of both through holes 11, further enhancing the waterproof reliability of the waterproof structure.

[0048] Optionally, at least one cover 20 is further provided with a through hole 25, which is spaced apart from the annular receiving recess 21 and communicates with the through hole 11. The through hole 11 and the through hole 25 are used for the wires 101 of the battery module 1 to pass through. The wall of the through hole 25 and the end face of the battery module 1 covered with the heat-shrinkable component 10 form a receiving groove for accommodating sealant. Thus, the above-mentioned arrangement of the through hole 25 allows the wires 101 of the battery module 1 to extend outside the waterproof structure for connection with external electrical load equipment, ensuring the power supply function of the battery module 1. Simultaneously, workers can apply sealant to the receiving groove to seal the gap at the through hole 25, further improving the waterproof reliability of the waterproof structure.

[0049] Specifically, the size of the through hole 25 can be smaller than the size of the through hole 11, that is, the hole wall of the through hole 25 forms a receiving groove only between the battery module 1, so as to seal the gap between the through hole 25 of the cover 20 and the battery module 1 through the sealing adhesive; the size of the through hole 25 can also be larger than the size of the through hole 11, that is, the hole wall of the through hole 25 forms a receiving groove between the battery module 1 and the heat shrinkable component 10 at the same time, and the sealing adhesive can seal the gap between the through hole 25 of the cover 20 and the heat shrinkable component 10 while also further sealing the gap between the through hole 11 of the heat shrinkable component 10 and the battery module 1.

[0050] Specifically, the sealant applied to the receiving groove can also seal the protruding part of the wire 101 of the battery module 1 after it solidifies.

[0051] In this embodiment, at least a portion of the cover 20 is made of a transparent material. This allows the worker to observe the sealing compound filling status within the first annular receiving cavity 30 and the second annular receiving cavity 40 through the transparent portion of the cover 20 during the pressing process. If insufficient filling occurs, the cover 20 can be promptly removed and the sealing compound reapplied, further enhancing the waterproof reliability of the waterproof structure.

[0052] In this embodiment, the cover 20 is entirely transparent.

[0053] As can be seen, the waterproof structure in this embodiment has the following advantages:

[0054] 1. Higher waterproof reliability: The traditional waterproof structure of waterproof foam and adhesive backing is eliminated. Instead, a sealant is directly bonded to the plastic material (cover 20 and heat shrink part 10), resulting in better adhesion and a higher waterproof rating even after long-term use and aging.

[0055] 2. Simple process: The traditional waterproof structure of waterproof foam plus adhesive backing requires ensuring the flatness of the waterproof foam, which is difficult to control. In this embodiment, the adhesive is applied directly to the inner ring of the blister shell (cover 20), without working directly on the battery module, making the process and operation simpler and more convenient.

[0056] 3. Compact structure: This embodiment actually uses heat shrink tubing + blister packs at both ends for sealing, unlike foam which has a larger overall volume, making the waterproof structure and the battery pack (battery module 1) with waterproof structure more compact.

[0057] 4. Low cost: Compared with the traditional method of pasting waterproof foam, the processing cost of the waterproof structure in this embodiment and the time cost of assembly by workers are both lower.

[0058] like Figure 1 As shown, this application also provides a battery device, which includes a battery module 1 and a waterproof structure, with at least a portion of the battery module 1 located within a receiving cavity of the waterproof structure. The waterproof structure is the one described above.

[0059] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0060] The heat-shrinkable component with a waterproof structure has a receiving cavity and a through hole communicating with the receiving cavity. The through hole is used for installing a battery module into the receiving cavity. After being heated and shrunk, the heat-shrinkable component covers the outer surface of the battery module. A cover is provided at the through hole and has an annular receiving recess. At least a portion of the opening of the annular receiving recess is disposed opposite to the heat-shrinkable component, so that the inner wall of the annular receiving recess and the heat-shrinkable component surround to form a first annular receiving cavity; or, the inner wall of the annular receiving recess and the heat-shrinkable component and the battery module surround to form a first annular receiving cavity. The first annular receiving cavity is used to receive a sealing adhesive. In this way, after the worker places the battery module into the receiving cavity and heats the heat-shrinkable component to cover the battery module, a sealant with a certain amount of excess (slightly overflowing the annular receiving recess) can be applied to the annular receiving recess of the cover. Then, the cover is placed on the through hole. Since at least part of the opening of the annular receiving recess is positioned opposite the heat-shrinkable component, the through hole is located entirely within the inner ring of the first annular receiving cavity. That is, the sealant in the first annular receiving cavity forms a sealing area between the cover and the heat-shrinkable component, reliably sealing the through hole. This solves the problem of poor waterproof reliability in existing battery pack waterproof structures. Furthermore, the worker only needs to apply the sealant and place the cover to complete the sealing operation, making the entire process very simple and quick. There is no need to worry about wrinkles in the waterproof foam, which not only improves the worker's work efficiency but also enhances the overall aesthetic appearance of the battery device.
