[0002] Currently, battery modules in the energy storage industry are mostly secured using end plates. This method typically involves using steel strapping to bind the battery cells to the end plates, which are then secured together to complete the overall securement of the energy storage module. However, this traditional securing method has certain limitations, such as limited fixing strength and an inability to effectively integrate other components (such as the battery management system (BMS)). This makes this securing method relatively simple and incapable of achieving multifunctionality. Utility Model Content

The limiting column is movably inserted into the positioning hole to limit the movement of the BMS part along the length direction of the first limiting plate; the fixing part passes through the connecting hole and is threadedly engaged with it.

[0010] In the above-mentioned multi-purpose module fixing structure, the positioning part includes a limiting hole and a through hole that are not connected to each other, a positioning plate and a connecting seat are provided in the accommodating cavity, and a threaded hole is provided in the connecting seat.

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 4 As shown, the utility model provides a multi-purpose module fixing structure for fixing the energy storage module 2 in the box body 1, wherein the box body 1 is provided with a accommodating cavity 10, and the energy storage module 2 is placed in the accommodating cavity 10; the pressure strip 3 has a first limiting plate 30 and a second limiting plate 31, the first limiting plate 30 is arranged horizontally and is movably clamped to the top wall of the energy storage module 2, the second limiting plate 31 is arranged in the vertical direction and is connected to the two ends of the first limiting plate 30, and is movably pressed against the two side walls of the energy storage module 2; the connecting part 4 and the positioning part 5, the connecting part 4 is arranged on the first limiting plate 30, and is used to receive and fix the BMS part 6 above the energy storage module 2; the positioning part 5 is arranged at the bottom of the second limiting plate 31, and can limit the displacement of the energy storage module 2 relative to the box body 1 when the positioning part 5 is connected to the inner wall of the accommodating cavity 10.

[0026] This solution is mainly to achieve the fixation of the energy storage module 2, such as Figures 1 to 4 As shown, when the required energy storage module 2 is placed in the accommodating cavity 10 of the corresponding box body 1, the worker can press the pressure strip 3 onto the energy storage module 2. Specifically, the position of the pressure strip 3 on the energy storage module 2 is limited by the first limiting plate 30 and the energy storage module 2 being movably connected to ensure a stable connection between the second limiting plate 31 and the box body 1; as the first limiting plate 30 is pressed, the second limiting plate 31 perpendicular to it can drive the positioning part 5 close to the bottom wall of the accommodating cavity 10 to achieve a fixed connection between the pressure strip 3 and the box body 1, ensuring that the energy storage module 2 will not be displaced in the box body 1. As for the BMS component 6 to be installed above the energy storage module 2, the connecting portion 4 on the first limiting plate 30 can be used to connect and fix the BMS component 6. That is to say, the pressure strip 3 can not only achieve the effect of pressing and fixing the energy storage module 2, effectively improving the fixing strength of the energy storage module 2, but also can use the connecting portion 4 to undertake and fix the BMS component 6 on this basis, safely and securely, so as to achieve the dual-purpose effect of the pressure strip 3.

[0027] Module blocks 20 are symmetrically arranged on the energy storage module 2, and a module groove 200 is formed between the two module blocks 20. The two side walls in the length direction of the first limiting plate 30 are formed with first flanges 300 in the vertical direction, and when the first limiting plate 30 is placed in the module groove 200, the first flanges 300 are movable against the module block 20.

[0028] Further, if Figure 1 and Figure 4 As shown, this solution utilizes the module groove 200 formed between the two module blocks 20 on the energy storage module 2. When the first limiting plate 30 is movably pressed into the module groove 200, the first flanges 300 on both sides are movably pressed against the two side walls of the module groove 200, thereby achieving a certain limiting effect, preventing the first limiting plate 30 from sliding relative to the top wall of the energy storage module 2, and also providing a guarantee for the stability of the fixed connection between the second limiting plate 31 and the inner wall of the box body 1.

[0029] Preferably, the first limiting plate 30 and the second limiting plate 31 in this solution are integrally injection molded. This manufacturing method effectively ensures the overall strength of the pressure strip 3, provides a guarantee for the pressure strip 3 to press and fix the energy storage module 2, and provides a guarantee for the stability of the BMS component 6 when it is supported and fixed.

[0030] The connecting part 4 includes a limiting column 40 and a fixing part 41. A positioning hole 60 and a connecting hole 61 are provided on the BMS part 6. The limiting column 40 is movably inserted into the positioning hole 60 to limit the movement of the BMS part 6 along the length direction of the first limiting plate 30; the fixing part 41 passes through the connecting hole 61 and is threadedly engaged with it.

[0031] Specifically, such as Figure 4 As shown, after the above-mentioned positioning portion 5 is fixedly connected to the inner wall of the accommodating cavity 10 in the box body 1, the limiting column 40 can be movably inserted into the positioning hole 60 to position and install the BMS component 6 as a whole. At the same time, through the threaded cooperation between the fixing part 41 and the connecting hole 61, the effect of receiving and fixing the BMS component 6 is achieved, effectively ensuring the stability between the BMS component 6 and the energy storage module 2.

[0032] The positioning portion 5 includes a limiting hole 50 and a through hole 51 that are not connected to each other. A positioning plate 100 and a connecting seat 101 are provided in the accommodating cavity 10, and a threaded hole 101a is provided in the connecting seat 101. The positioning plate 100 is movably inserted in the limiting hole 50 so that the threaded hole 101a is aligned with the through hole 51 for fixing the connecting part.

[0033] Further, if Figure 3As shown, the limiting hole 50 and the through hole 51 in this scheme are both arranged at the bottom of the second limiting plate 31 of the positioning part 5. As the above-mentioned first limiting plate 30 is movably engaged in the module groove 200, the positioning plate 100 on the bottom wall of the accommodating cavity 10 is also movably inserted into the limiting hole 50, thereby pre-positioning the second limiting plate 31. For this reason, the threaded hole 101a on the connecting seat 101 and the through hole 51 are exactly in a coaxial placement relationship, so that the connecting part passes through the through hole 51 and the threaded hole 101a to realize the fixed connection between the second limiting plate 31 and the box body 1. The overall structure is relatively simple, the installation operation is convenient and quick, and it also provides convenience for subsequent maintenance and replacement.

[0034] The accommodating cavity 10 also forms a limiting groove 102, and the limiting plate and the connecting seat 101 are placed on both sides of the limiting groove 102, so that when the energy storage module 2 is placed in the limiting groove 102, the positioning portion 5 can be connected to the box 1.

[0035] like Figure 2 As shown, the present solution also utilizes the limiting groove 102 in the accommodating cavity 10 to limit the installation and placement of the energy storage module 2, that is, the limiting groove 102 is utilized to limit the position of the energy storage module 2 in the accommodating cavity 10, ensuring that when the first limiting plate 30 on the pressure strip 3 is pressed tightly against the energy storage module 2, the limiting hole 50 and the through hole 51 on the second limiting plate 31 can be stably fixedly matched with the positioning plate 100 and the threaded hole 101a, thereby providing a guarantee for the pressure strip 3 to achieve stable fixation of the energy storage module 2.

[0036] Preferably, this solution also forms second flanges 310 on both side walls of the second limiting plate 31 in the vertical direction, and the second flanges 310 are used to strengthen the strength of the fixed connection of the pressure strip 3, thereby effectively improving the fixing strength of the energy storage module 2.

[0037] It should be noted that the fixing member 41 and the connecting member in this solution can be replaced by screws, bolts or other connecting members.

[0038] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, terms such as "first," "second," and "an" in this utility model are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0040] In this utility model, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.
