Description

Technical Field

[0008]

[0001] The utility model relates to the technical field of batteries, and particularly relates to a high-strength and lightweight battery module box. Background Art

[0002] The battery module box is an indispensable component in equipment such as electric vehicles and energy storage systems; it can provide physical protection for the internal battery modules, resist mechanical damages such as external collisions and squeezes, and its materials are mostly metal or plastic, which need to meet strength, corrosion resistance, etc. Functionally, it not only needs to ensure the safety of the battery modules, but also needs to create conditions for the electrical connection and heat dissipation of the battery modules; a reasonable hole-opening design can assist heat dissipation, and specific structures such as nuts and nut columns facilitate the installation and electrical connection of the battery modules and related components, ensuring the stable and efficient operation of the entire battery system.

[0003] As the key bearing structure of the battery module, its strength and lightweight design are crucial in practical applications. Under the existing technical conditions, if a relatively thin plate is used to make the module box, restricted by the physical properties of the material itself, it is difficult to meet the sufficient strength requirements, and it is extremely easy to deform under working conditions such as external pressure and impact, thereby affecting the stability and safety of the internal battery modules and unable to reliably ensure the normal operation of the battery system. However, if the plate thickness is simply increased to ensure strength, although the structural strength can be improved, it will lead to an increase in material costs and a significant increase in the overall weight, which is contrary to the development trend of modern equipment pursuing lightweight, high performance, and cost optimization.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Content of the Utility Model

[0005] The utility model aims to provide a technical solution that can solve the above problems in order to overcome the above deficiencies.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a high-strength and lightweight battery module box, including a box body, and a strengthening framework is arranged inside the box body;

[0007] The box body includes a main frame in a "U" shape composed of a bottom plate and side plates, a back plate connected to the back of the main frame, and a top cover connected to the upper end of the main frame;

[0008] The strengthening framework includes support columns arranged at two connection angles of the main frame, the back plate, and the top cover. A cross column is connected between the upper and lower ends of the two support columns. Two adjacent sides of the cross column are respectively connected to the bottom plate of the main frame and the back plate. An upper vertical column and a lower vertical column are also connected to the support column. Two adjacent sides of the upper vertical column are respectively connected to the top cover and the side plate of the main frame. Two adjacent sides of the lower vertical column are respectively connected to the bottom plate and the side plate of the main frame.

[0009] As a further embodiment of this utility model, the reinforcing frame also includes reinforcing columns disposed between the two horizontal columns and between the upper and lower vertical columns.

[0010] As a further embodiment of this utility model: a plurality of limiting posts are provided on the main frame, and one end of each limiting post is connected to a horizontal post.

[0011] As a further embodiment of this utility model: a blocking block is provided at the end of the limiting post facing the horizontal column, the blocking block is provided with a screw hole, and several adjustment holes corresponding to the screw holes are provided on both the horizontal column and the back plate, and the multiple adjustment holes are evenly distributed in an array.

[0012] It also includes bolts, which pass through the adjustment hole and are screwed into the screw hole for fixation.

[0013] As a further embodiment of this utility model: the supporting column, horizontal column, upper vertical column, lower vertical column, reinforcing column, and limiting column are all square tubes with hollow structures.

[0014] As a further embodiment of this utility model: a second blocking block is provided at the end of the upper and lower vertical columns away from the back plate.

[0015] As a further aspect of this utility model, the housing is provided with multiple heat dissipation holes.

[0016] As a further embodiment of this utility model: the box body is provided with a plurality of dustproof mesh plates corresponding to the heat dissipation holes.

[0017] Compared with existing technologies, the beneficial effects of this technical solution are as follows: the box is composed of a main frame and a top cover, with a loading port on one side for loading battery modules. By setting a reinforcing frame composed of support columns, horizontal columns, upper vertical columns and lower vertical columns inside the box, the connection angle between the main frame, back plate and top cover is strengthened, improving the stability between the various components of the box and better resisting external pressure. This effectively enhances the deformation resistance and structural strength of the box without increasing the thickness of the sheet metal, and also takes into account lightweighting and cost control.

Detailed implementation manners

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figure 1-4 , a high-strength and lightweight battery module box, including a box body 1, and a reinforcing skeleton 2 is arranged inside the box body 1; [[ID=XXX]] [[ID=XXX]]

[0028] The box body 1 includes a main frame 11 in a "U" shape composed of a bottom plate and side plates, a back panel 12 connected to the back of the main frame 11, and a top cover 13 connected to the upper end of the main frame 11; [[ID=XXX]] [[ID=XXX]]

[0029] The reinforcing frame 2 includes support columns 21 set at two connecting angles of the main frame 11, the back plate 12, and the top cover 13. A horizontal column 22 is connected between the upper and lower ends of the two support columns 21. The two adjacent sides of the horizontal column 22 are connected to the bottom plate of the main frame 11 and the back plate 12, respectively. An upper vertical column 23 and a lower vertical column 24 are also connected to the support columns 21. The two adjacent sides of the upper vertical column 23 are connected to the top cover 13 and the side plate of the main frame 11, respectively. The two adjacent sides of the lower vertical column 24 are connected to the bottom plate and the side plate of the main frame 11, respectively.

[0030] Specifically, the housing 1 consists of a main frame 11, a back plate 12 and a top cover 13, and has a loading port on one side for loading battery modules. The structural strength of the housing 1 is improved by setting a reinforcing frame 2 inside the housing 1.

[0031] More specifically, the reinforced frame 2 consists of a support system composed of support columns 21, horizontal columns 22, upper vertical columns 23, and lower vertical columns 24. All support columns 21, 22, 23, and 24 are square columns. Support columns 21 connect to the main frame 11, back panel 12, and top cover 13 at two connecting angles, with two adjacent sides connecting to the side panels of the back panel 12 and main frame 11 respectively. The upper and lower ends connect to the top cover 13 and the bottom plate of the main frame 11 respectively. The two horizontal columns 22 are connected at both ends to the two support columns 21. The upper horizontal column 22... The lower horizontal column 22 is connected to the back panel 12 and the top cover 13, while the upper vertical column 23 is connected to the top cover 13 and the side panel of the main frame 11. The lower vertical column 24 is connected to the bottom plate and the side plate of the main frame 11. This strengthens the connection angle between the main frame 11, the back panel 12 and the top cover 13, improves the stability between the components of the box 1, and can better resist external pressure. Without increasing the thickness of the plate, it effectively enhances the deformation resistance and structural strength of the box 1, and can also take into account lightweight and cost control.

[0032] In some embodiments, the reinforcing frame 2 further includes reinforcing columns 25 disposed between the two horizontal columns 22 and between the upper vertical column 23 and the lower vertical column 24.

[0033] Specifically, by reinforcing the column 25, not only can the deformation resistance of the box be further improved, but the overall stability of the reinforced frame 2 can also be improved by supporting the two horizontal columns 22 and the upper vertical column 23 and the lower vertical column 24, thus preventing the connection points between the various components of the reinforced frame 2 from becoming loose.

[0034] In some embodiments, a plurality of limiting posts 3 are provided on the main frame 11, and one end of the limiting post 3 is connected to the horizontal post 22.

[0035] Specifically, by setting several limiting posts 3 on the main frame 11, taking two limiting posts 3 as an example, when loading the battery module, the battery module can be pre-limited by blocking it with the limiting posts 3, which facilitates the fixing of the battery module after the subsequent loading is completed.

[0036] In some embodiments, a blocking block 4 is provided at one end of the limiting post 3 facing the horizontal post 22. The blocking block 4 is provided with a screw hole 41. The horizontal post 22 and the back plate 12 are provided with a plurality of adjustment holes 5 that correspond to the screw hole 41, and the plurality of adjustment holes 5 are evenly distributed in an array.

[0037] It also includes bolt 6, which passes through the adjustment hole 5 and is screwed into the screw hole 41 for fixation.

[0038] For details, please refer to Figures 3-4 The position of the limiting post 3 can be adjusted by unscrewing the bolt 6 and aligning it with the adjustment hole 5 at different positions. Then, the bolt 6 is screwed in to fix the position of the limiting post 3, so that the spacing between the limiting posts 3 can be adjusted or the number of limiting posts 3 can be increased, thereby enabling the pre-positioning of battery modules of different sizes.

[0039] In some embodiments, the support column 21, horizontal column 22, upper vertical column 23, lower vertical column 24, reinforcing column 25, and limiting column 3 are all square tubes with hollow structures; in order to significantly reduce the structural weight and improve material utilization while maintaining strength.

[0040] Among them, the block 4 is embedded inside the hollow structure of the limiting column 3.

[0041] In some embodiments, a second blocking block 7 is provided at the end of the upper vertical column 23 and the lower vertical column 24 away from the back plate 12.

[0042] Specifically, the second block 7 is embedded inside the hollow structure of the upper vertical column 23 and the lower vertical column 24, and is provided with a screw hole 2 to facilitate the installation of the cover after the battery module is transferred into the housing 1.

[0043] In some embodiments, the housing 1 is provided with multiple heat dissipation holes 8 to facilitate the dissipation of heat generated by the battery module during operation, thereby preventing the battery module from overheating and affecting its performance.

[0044] In some embodiments, the housing 1 is provided with a plurality of dustproof mesh plates 9 corresponding to the heat dissipation holes 8. The dustproof mesh plates 9 cover the heat dissipation holes 8 to prevent dust from entering the housing 1 from the heat dissipation holes 8 and coming into contact with the battery module, thereby avoiding electrical accidents caused by dust. At the same time, the mesh structure of the dustproof mesh plate 9 can ensure that the air permeability is not affected too much, so that the heat dissipation of the battery module is still effective.

[0045] Preferably, the main frame 11, the back plate 12, and the top cover 13 can be fixed together by welding.

[0046] More preferably, the reinforcing frame 2 and the box body 1 can be fixed together by welding.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
