Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a modular lead-acid battery casing. Background Technology

[0002] In practical applications of lead-acid batteries, whether it is a small backup power system or a large energy storage power station, it is often necessary to combine multiple battery cells into battery packs to meet different power demands.

[0003] However, existing technologies have some problems: traditional lead-acid battery casings have obvious defects in assembly. Their assembly method is fixed and complex, requiring additional fastening devices and complex wiring processes. This not only consumes a lot of manpower and time, but also easily leads to unstable battery pack connections due to improper assembly, affecting overall performance. At the same time, as the power of battery packs continues to increase, the heat generated by the batteries during charging and discharging is also increasing. Traditional casing designs fail to fully consider the heat dissipation problem between batteries. The close arrangement of batteries results in insufficient heat dissipation space, making it difficult for heat to dissipate, which in turn leads to excessively high battery temperatures, accelerates battery aging, reduces battery life, and even poses safety hazards. Therefore, we propose a modular lead-acid battery casing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a modular lead-acid battery casing that allows for convenient assembly in any direction while effectively ensuring the battery's heat dissipation distance.

[0005] The purpose of this utility model is achieved as follows: a modular lead-acid battery casing, including a top cover and a housing, wherein the top cover is movably snapped onto the top of the housing, and the surface of the housing is provided with a snap-fit ​​assembly, which allows adjacent housings to be assembled together quickly. The snap-fit ​​assembly includes recessed grooves and protrusions, and the recessed grooves and protrusions on two adjacent housings can fit together to achieve the splicing of the housings. A heat dissipation channel is formed between the two recessed grooves and the two protrusions.

[0006] Optionally, the recessed groove and the protrusion have the same shape, and the dimensions of the recessed groove and the protrusion are matched.

[0007] Optionally, the recessed grooves are distributed on two adjacent sides of the vertical surface of the housing, and the protrusions are distributed on the other two sides of the vertical surface of the housing, with the recessed grooves and protrusions arranged in a centrally symmetrical manner.

[0008] Optionally, the heat dissipation channels are evenly distributed on the surface of the housing, and the height of the heat dissipation channels is the same as the height of the recessed grooves.

[0009] Optionally, the housing is generally rectangular, and the height of the housing is greater than the height of the recessed groove and the protrusion.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention, by setting recessed grooves, protrusions, and heat dissipation channels, achieves rapid assembly through the interlocking of the recessed grooves and protrusions, eliminating the need for additional fastening devices and complex wiring processes. This significantly improves assembly efficiency, reduces labor and time costs, and minimizes connection instability caused by improper assembly, thereby enhancing the overall performance of the battery pack. Furthermore, the heat dissipation channel design effectively ensures the heat dissipation distance between batteries, allowing the heat generated during charging and discharging to dissipate in a timely manner, preventing overheating, extending battery life, and improving battery safety and reliability.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown in the figure, a modular lead-acid battery casing provided by this utility model embodiment includes an upper cover 1 and a housing 2. The upper cover 1 is movably snapped onto the top of the housing 2. The surface of the housing 2 is provided with a snap-fit ​​assembly. Adjacent housings 2 can be assembled with the snap-fit ​​assembly to achieve quick splicing. The snap-fit ​​assembly includes a recessed groove 3 and a protrusion 4. The recessed groove 3 and the protrusion 4 on two adjacent housings 2 can fit into each other to achieve splicing of the housings 2. A heat dissipation channel 5 is formed between the two recessed grooves 3 and the two protrusions 4.

[0021] Furthermore, the recessed groove 3 and the protrusion 4 have the same shape, and their sizes are matched.

[0022] The cross-sectional shape of the recessed groove 3 and the protrusion 4 is one of trapezoidal, rectangular or semi-circular. For example, the horizontal cross-sectional shape of the protrusion 4 in the attached figure is trapezoidal, and the size can be set to 5mm for the upper base, 8mm for the lower base and 5mm for the height. The horizontal cross-sectional shape of the recessed groove 3 is also trapezoidal, and the size matches that of the protrusion 4, which can ensure that the protrusion 4 is tightly embedded in the recessed groove 3.

[0023] Furthermore, the recessed grooves 3 are distributed on two adjacent sides of the vertical surface of the housing 2, and the protrusions 4 are distributed on the other two sides of the vertical surface of the housing 2. The recessed grooves 3 and the protrusions 4 are arranged in a centrally symmetrical manner.

[0024] By setting the positions of the recessed groove 3 and the protrusion 4, the shell 2 can be spliced ​​in different directions according to the requirements, thereby improving the splicing flexibility.

[0025] Furthermore, heat dissipation channels 5 are evenly distributed on the surface of the housing 2, and the height of the heat dissipation channels 5 is the same as the height of the recessed groove 3.

[0026] After adjacent housings 2 are spliced ​​together, the heat dissipation channel 5 ensures the distance for battery heat dissipation and ensures smooth airflow between housings 2.

[0027] Furthermore, the shell 2 is generally rectangular, and the height of the shell 2 is greater than the height of the recessed groove 3 and the protrusion 4.

[0028] The housing 2 can be made of materials with good insulation properties such as ABS or PP, thereby preventing safety hazards such as leakage.

[0029] Working principle and usage process of this utility model:

[0030] For small backup power systems, the number of battery cells required is usually small. The operator selects a suitable assembly method according to the actual installation space and layout requirements. The protrusion 4 on one housing 2 is aligned with the recessed groove 3 on the adjacent housing 2, and the protrusion 4 is gently pressed to make it fully embedded in the recessed groove 3, so as to achieve quick splicing. Multiple housings 2 are spliced ​​together in this way to form the required battery pack. During the splicing process, no additional fastening device is required. The stability of the connection can be guaranteed by the tight fit between the recessed groove 3 and the protrusion 4.

[0031] In the application scenarios of large-scale energy storage power stations, a large number of battery cells need to be combined into large-scale battery packs. At this time, a modular assembly method can be adopted. First, a certain number of battery cells are assembled into small modules through the recessed grooves 3 and protrusions 4 on the shell 2. The number of modules to be assembled is determined according to the actual weight and volume. These small modules are pre-assembled on the ground to form relatively independent units. Then, hoisting equipment is used to lift these units to the designated installation position, and then the units are spliced ​​together.

[0032] When adjacent housings 2 are joined together by recessed grooves 3 and protrusions 4, due to the design of the heat dissipation channel 5, the heat generated by the charging and discharging of the battery during the operation of the battery pack will raise the temperature of the surrounding air. The hot air will rise naturally and flow upward through the heat dissipation channel 5. At the same time, cold air will be replenished from below, forming natural air convection, ensuring that the heat generated by the battery can be dissipated in time and avoiding the battery temperature from getting too high.

[0033] This invention successfully solves the problems of assembly convenience and heat dissipation in traditional lead-acid batteries, significantly improving the assembly efficiency, connection stability and heat dissipation performance of battery packs. It provides strong support for the widespread application of lead-acid batteries in more fields and has broad market prospects and huge economic value.

[0034] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
