Specific embodiments

[0026] Referring to Figures 1-7 , the present utility model relates to a battery module with a front cover plate that can be quickly plugged in, including a front cover plate 1, a battery module housing 2, and a battery cell assembly 3. The battery cell assemblies 3 are arranged in an array in the battery module housing 2. The front side of the battery module housing 2 is plugged with an upper cover plate 1. The upper cover plate 1 is of a split type and includes an upper cover 1.1 and a lower cover 1.2 that are plugged up and down. The upper cover 1.1 and the lower cover 1.2 are integrally injection molded respectively. The back of the upper cover 1.1 is symmetrically provided with first horizontal buckles 1.1.1 on the left and right. The battery module housing 2 is provided with first card slots 2.1 corresponding to the first horizontal buckles 1.1.1. The back of the lower cover 1.2 is symmetrically provided with second horizontal buckles 1.2.1 on the left and right. The battery module housing 2 is provided with second card slots 2.2 corresponding to the second horizontal buckles 1.2.1. The second card slots 2.2 are symmetrically arranged on the left and right side parts of the battery module housing 2. The first card slots 2.1 on the same side are arranged above the inner side of the second card slots 2.2. The card slots and the buckles correspond one by one. Through simple pressing, the buckles can be quickly locked, thereby realizing the quick plugging function of the front cover plate. This structure not only simplifies the assembly process but also facilitates later maintenance and repair.

[0027] On the top of the lower cover 1.2, vertical card slots 1.2.2 are symmetrically arranged on the left and right. On the bottom of the upper cover 1.2, vertical buckles 1.1.2 are provided corresponding to the vertical card slots 1.2.2. On the top of the lower cover 1.2, vertical limiting pieces 1.2.3 are further provided. The vertical limiting pieces 1.2.3 are attached to the inner side wall of the upper cover 1.2 to ensure that the upper cover 1.1 and the lower cover 1.2 are parallel in the vertical direction, so that the first horizontal buckle 1.1.1 and the second horizontal buckle 1.2.1 are kept parallel, facilitating the quick insertion of the front cover plate 1 into the battery module housing 2.

[0028] In order to make the insertion of the front cover plate 1 into the battery module housing 2 stable, an installation seat 4 is further provided between the battery module housing 2 and the front cover plate 1. The installation seat 4 is integrally injection-molded. The installation seat 4 is fixed on the battery module housing 2. Reinforcing card slots 4.1 are symmetrically arranged on the left and right sides of the installation seat 4. The lower cover 1.2 is provided with reinforcing buckles 1.2.4 corresponding to the reinforcing card slots 4.1. The reinforcing buckles 1.2.4 are arranged inside the second horizontal buckle 1.2.1. There are 4 reinforcing buckles 1.2.4, 2 on each side, and two are arranged at intervals up and down on each side.

[0029] A plug of a connecting wire 5 is provided on the battery module housing 2. The plug of the connecting wire 5 is connected to the positive and negative copper bars of the battery cell assembly 3. The upper cover 1.1 is provided with a plug receiving cavity 1.1.3 corresponding to the plug of the connecting wire 5. Notches 1.1.4 are respectively provided on the upper and lower cavity walls of the plug receiving cavity 1.1.3. The notches 1.1.4 arranged up and down correspond to each other. The notches 1.1.4 facilitate the layout of the positive and negative connecting copper bars, ensuring the smoothness and safety of the electrical connection.

[0030] A first plastic sheet 1.1.5 is connected in a point-by-point manner on the upper cavity wall of the plug receiving cavity 1.1.3. A second plastic sheet 1.2.5 is connected in a point-by-point manner on the side wall of the lower cover 1.2. A third plastic sheet 1.2.6 is connected in a point-by-point manner on the bottom wall of the lower cover 1.2. By setting the plastic sheets in a point-by-point manner, it can be flexibly adjusted according to different wiring strategies. Just simply break the corresponding plastic sheet to achieve the optimization of the circuit. When choosing the daisy-chain wiring mode, the first plastic sheet 1.1.5 and the third plastic sheet 1.2.6 can be easily removed; while when adopting the hand-in-hand wiring scheme, the second plastic sheet 1.2.5 can be removed for wiring. Such a design greatly improves the flexibility and convenience of installation and maintenance. Figure 7Shows the wiring design behind the front cover plate, which cleverly accommodates two different wiring methods: daisy chain and hand-in-hand. The hand-in-hand wiring method allows the wires to enter from the upper end of the front cover plate and directly reach the lower end, which is suitable for situations where a straight connection is required; while the daisy chain wiring method enables the wires to be connected one by one like a chain, and this method is very suitable for situations where electrical connections are needed at multiple points. The compatibility of these two wiring methods not only provides greater flexibility to adapt to different application scenarios and electrical requirements, but also optimizes wire management, ensuring the neatness and reliability of the internal wiring.

[0031] The lower cover 1.2 is provided with a circular marking area 1.2.7, and the circular marking area 1.2.7 is provided with positioning holes, and the nameplate is accurately positioned through the positioning holes.

[0032] The lower cover 1.2 is also provided with an inclined air duct 1.2.8, and the air duct 1.2.8 penetrates through the front and rear sides of the lower cover 1.2, and the lowest part of the air duct 1.2.8 is the air outlet. The air duct effectively guides the heat dissipated by the module to be discharged downward, can quickly discharge the hot air, significantly improves the heat dissipation efficiency, ensures the stability and durability of the equipment operation, and at the same time reduces the energy consumption.

[0033] In addition to the above embodiments, the present utility model also includes other implementation manners. Any technical solutions formed by equivalent transformation or equivalent substitution shall fall within the protection scope of the claims of the present utility model.
