Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery cell module that can be injected with adhesive. Background Technology

[0002] Currently, lithium battery cell modules using ternary materials require the injection of expanding foam to prevent heat transfer between cells.

[0003] However, currently, the sides of lithium battery cell modules are hollowed out. During the potting process, fixtures are needed to cover the sides of the lithium battery cell module to prevent the expanding foam from flowing out. As a result, a large amount of glue will adhere to the fixtures, leading to insufficient glue inside the lithium battery cell module when the fixtures are removed. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a battery cell module that can be glued. This not only replaces the method of using tooling fixtures to cover the sides of the lithium battery cell module to complete the glue filling, but also ensures that there is a sufficient amount of glue inside the lithium battery cell module.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] The first aspect of this application provides a battery cell module that can be injected with adhesive, comprising: a base, the base including a receiving box having an installation groove for placing a lithium battery cell module; and a fastening assembly including a cover disposed on the receiving box, the cover having an adhesive injection port in the middle.

[0007] The cover is also provided with a vent, which is connected to the mounting groove.

[0008] It also includes several busbars, each of which is spaced apart on the cover.

[0009] The base also includes a snap-fit ​​protrusion, which is disposed on the receiving box.

[0010] The base also includes a first positioning strip, which is disposed on the receiving box.

[0011] The fastening assembly further includes a second positioning strip, which is disposed on the cover.

[0012] The fastening assembly also includes a fixing block, which is disposed on the cover and has a wiring groove.

[0013] The fastening assembly further includes a retaining post, which is disposed on the cover.

[0014] The fastening assembly further includes a first chamfered portion, which is disposed on the cover.

[0015] The base also includes a second chamfered portion, which is disposed on the receiving box.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] This application involves directly inserting the lithium battery cell module into the mounting slot of the receiving box, then attaching the cover to the receiving box, and injecting expanding foam through the injection port. The two side walls of the mounting slot can resist the adhesive material, preventing it from overflowing and ensuring sufficient adhesive material inside the lithium battery cell module. Attached Figure Description

[0018] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments will be briefly described below.

[0022] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0023] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0024] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0025] Currently, the sides of lithium battery cell modules are hollowed out. During the potting process, fixtures are needed to cover the sides of the lithium battery cell module to prevent the expanding foam from leaking out. As a result, when it's time to remove the fixture after the foam has fully expanded, a large amount of glue will adhere to the fixture, making disassembly very difficult. In addition, relying solely on fixtures for protection can also cause expanding foam to overflow inside the lithium battery cell module.

[0026] To address the aforementioned issues, this application provides a battery cell module that can be glued, which not only replaces the method of using tooling fixtures to cover the sides of the lithium battery cell module for glue filling, but also ensures sufficient glue content within the lithium battery cell module.

[0027] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1 , Figure 2 and Figure 3 A battery cell module that can be injected with adhesive includes: a base 100 and a fastening assembly 200. The base 100 includes a receiving box 110, and the receiving box 110 has an installation groove 111 for placing the lithium battery cell module 300. The fastening assembly 200 includes a cover 210, which is disposed on the receiving box 110, and the cover 210 has an adhesive injection port 211 in the middle.

[0029] It should be noted that in this application, the lithium battery cell module 300 is installed into the mounting groove 111 of the receiving box 110, and then the cover 210 is placed on the receiving box 110. Foam is injected through the glue injection port 211. The two side walls of the mounting groove 111 can resist the glue and prevent the glue from overflowing, ensuring that there is sufficient glue in the lithium battery cell module 300. Furthermore, the glue injection port 211 is located in the middle of the cover 210, which allows the glue to flow out evenly from the center to the surrounding area, ensuring that there is glue in the gaps between each cell.

[0030] Please see Figure 3 In one embodiment, the cover 210 is also provided with a vent 212, which is connected to the mounting groove 111.

[0031] It should be noted that by setting the vent 212, the air inside the rubber can be squeezed out, preventing the rubber from expanding and foaming and increasing the outline size of the container 110.

[0032] Please see Figure 3 An injectable battery cell module also includes several busbars 400, each of which is spaced apart on the cover 210.

[0033] It should be noted that several busbars 400 connect multiple lithium battery cells in series, meaning that this application can be used as a battery cell module without disassembling the housing box 110 after potting.

[0034] Please see Figure 2 In one embodiment, the base 100 further includes a snap-fit ​​protrusion 120 disposed on the receiving box 110.

[0037] It should be noted that by setting the first positioning strip 130 and the second positioning strip 220, the incorrect direction of the cover 210 can be prevented from being fastened, thus playing a role in preventing mistaken identity.

[0038] Please see Figure 1 In one embodiment, the fastening assembly 200 further includes a fixing block 230, which is disposed on the cover 210 and has a wiring groove 231.

[0039] It should be noted that the wiring channel 231 is used to facilitate the wiring of the battery cells.

[0040] Please see Figure 1 In one embodiment, the fastening assembly 200 further includes a retaining post 240 disposed on the cover 210.

[0041] It should be noted that the abutment post 240 facilitates the interlocking and stacking of the receiving boxes 110, that is, a through hole that mates with the abutment post 240 is provided at the bottom of the receiving box 110.

[0042] Please see Figure 1In one embodiment, the fastening assembly 200 further includes a first chamfered portion 250 disposed on the cover 210. Specifically, the base 100 further includes a second chamfered portion 140 disposed on the receiving box 110.

[0043] It should be noted that by setting the first chamfer 250, the corners of the cover 210 are made smoother, and by setting the second chamfer 140, the corners of the container 110 are made smoother.
