[0026] It should be noted that the following will illustrate the structural composition, characteristics and advantages of the assembly components, battery packs and electromechanical equipment for the battery module according to the present application by way of example, however, all descriptions shall not be used to form any limitation on the present application. In this article, the technical terms "first" and "second" are only used for distinguishing purposes and are not intended to indicate their order and relative importance. The technical term "pressing and clamping" means that after several assemblable parts are assembled, the battery module can be clamped and fixed by means of the pressing force applied by these assemblable parts to the battery module without displacement relative to the assemblable parts. In addition, in order to simplify the drawings, the same or similar parts and features may be marked only in one or several places in the same figure.

[0027] Please refer to Figures 1 to 6These drawings illustrate in an illustrative manner an embodiment of a battery module assembly component according to the present application and a general situation of using the same to install and fix a battery module example inside a battery pack shell example. The present application scheme will be described in detail below in conjunction with these examples.

[0028] The battery module 100 is a component used to construct the battery pack 400. According to different application requirements, the battery module 100 can be configured with two, three or more battery cells 10. Figure 3 The example specifically shows that six battery cells 10 are configured at this time, and of course the battery module 100 may also be a single battery cell. These battery cells 10 can generally have the same configuration, and they can be optionally stacked together to form a compact structural layout, for example, lithium battery cells can be stacked. Of course, in some applications, it is also allowed that one or some battery cells in the battery module 100 have a different configuration than other battery cells.

[0029] With the help of the assembly component 200 of the present application, the battery module 100 can be easily assembled and fixed to the inside of the shell 300. The entire assembly process is simple, efficient and labor-saving, and does not require the use of additional tools and equipment such as screws, adhesives, special frames, etc. that are commonly required in the prior art.

[0030] Specifically, as used in the example of the present application, the assembly component 200 may include two first parts 21 and two second parts 22, which may be optionally configured in a plate shape, so as to be more suitable for various types of battery modules. Figure 4 As shown in FIG. 1 and FIG. 2 , when in use, the two first parts 21 can be arranged relative to each other, and the two second parts 22 can be arranged relative to each other, and through the engagement between the engagement portion 211 on the first part 21 and the engagement portion 221 on the second part 22, the first part 21 and the second part 22 can be detachably assembled together, so that the assembled assembly 200 can press the battery module 100 along the periphery of the battery module 100 to form a force, so that the battery module 100 can be clamped and fixed by the assembly assembly 200. As an optional method, one or more dimensions of the accommodation space (such as a rectangle, etc.) defined by the assembled assemblable parts can be set to be smaller than the corresponding dimensions of the battery module, for example, the maximum transverse dimension (or maximum longitudinal dimension) of the above-mentioned accommodation space can be set to be smaller than the maximum transverse dimension (or maximum longitudinal dimension) of the battery module, so that the battery module can be pressed and clamped by such a size matching design to form an effect such as an interference fit. The specific size configuration between the assemblable parts and the battery module can be designed according to the actual application situation, as long as the pressing and clamping effect as described above can be achieved.

[0031] For the above assembly process, you can refer to Figure 3 and Figure 4 The accompanying drawings provide schematic illustrations of this.

[0032] The specific configuration of the joint part 211 and the joint part 221 can be specifically designed according to the actual application requirements, as long as they are configured to match and join, and this application does not impose any restrictions on this. Figure 1 , Figure 2 and Figure 3 Etc., the joint part 211 and the joint part 221 can be correspondingly constructed into matching slot shapes and hook shapes. During assembly, the hook-shaped joint part 221 is inserted into and passed through the slot-shaped joint part 211, and then the hook-shaped part is engaged with the slot part, and the first part 21 and the second part 22 are assembled and connected together accordingly. By respectively configuring the respective positions of the joint part 211 and the joint part 221 on the first part 21 and the two second parts 22, they can make the assembled first part 21 and the second part 22 press against the periphery of the battery module 100 after engagement, so that the battery cells 10 contained in the battery module 100 can be firmly clamped like a spring sheet without the need for additional fixing means such as screws, adhesives, special frames, etc. In this way, not only can the design, assembly and manufacture of the battery module be made simpler, but also it helps to improve production efficiency and reduce product costs.

[0033] The assembly component 200 may be provided with an assembly portion 23 so that the battery module 100 is mounted and fixed in the internal space 31 of the housing 300 through matching engagement between the assembly portion 23 and an installation portion 33 (e.g., in the form of a groove, etc.) arranged on the housing 300. As an optional situation, according to different application scenarios, it may be considered to arrange the assembly portion 23 on the first portion 21 and / or the second portion 22.

[0034] For example, Figure 5 and Figure 6As shown, the assembly portion 23 can be optionally arranged on the second portion 22, for example, the extension end on the second portion 22 can be directly used as the assembly portion 23, and the extension end will extend beyond the first portion 21 after the engagement portion 221 of the second portion 22 is engaged with the engagement portion 211 of the first portion 21, so that when the battery module 100 assembled with the assembly component 200 is arranged in the internal space 31 of the shell 300, the extension end can be used as the assembly portion 23 to match and engage with the mounting portion 33 which can be in the form of a groove at this time, so as to fix the battery module 100 in place inside the shell 300. As an optional situation, the extension ends of the two second portions 22 can be pressed against the inner wall of the groove after installation, so that the battery module 100 can be firmly and reliably fixed in place inside the shell 300 through the force formed like a spring sheet.

[0035] As an optional situation, as used in the example of the present application, the first part 21 can be constructed to have an extension portion 212. After the battery module 100 is fixed in place, it can be abutted against the inner wall 32 of the shell 300 through such an extension portion 212. This will prevent the battery module 100 from moving easily inside the shell 300 even when the battery pack 400 encounters vibration, impact, etc., thereby effectively enhancing the overall stability.

[0036] The above is an example of the assembly assembly according to the present application in combination with the examples in the drawings. It should be noted that the specific implementation of the assembly assembly, etc. should not be limited thereto. For example, the assembly assembly for the battery module can actually be composed of two or more assembleable parts. For example, the pair of first parts 21 and second parts 22 in the aforementioned embodiment can be integrated to form an assembleable part. By using two such assembleable parts for assembly, the good effect of pressing and clamping the battery module 100 and reliably fixing it in place inside the housing 300 can also be achieved.

[0037] For another example, according to the actual application configuration of the battery module 100 and its battery cell 10, the specific shape, size, material used, etc. of each assemblable part in the assembly assembly can be flexibly designed. For example, the first part 21 and the second part 22 in the aforementioned embodiment can be made of the same material (such as plastic, etc.) or different materials (such as plastic, aluminum alloy, etc.); for another example, the assemblable parts in the assembly assembly do not have to be arranged symmetrically; for another example, two or more battery modules 100 can be arranged inside the battery pack 400 as needed, and for different battery modules 100, their corresponding assembly assemblies can have the same or different configurations.

[0038] The present application further provides an electromechanical device, in which one or more battery packs designed and provided according to the present application can be configured and used according to actual application needs. It should be understood that the electromechanical device according to the present application is allowed to have a very wide range of applications, including but not limited to many types such as lighting equipment, refrigeration units, new energy vehicles, riding vehicles, etc.

[0039] The above only illustrates in detail the assembly components, battery packs and electromechanical devices for battery modules according to the present application by way of example. These examples are only used to illustrate the principles and implementation methods of the present application, and do not constitute a limitation on the present application. Without departing from the scope of the present application, those skilled in the art may also make various modifications and improvements. Therefore, all equivalent technical solutions shall belong to the scope of the present application and be defined by the claims of the present application.
