DETAILED DESCRIPTION

[0021] The specific embodiment of the utility model is further explained in detail by the description of the embodiment by comparing with the drawings, the purpose is to help the technical personnel in the field to have more complete, accurate and in-depth understanding to the inventive concept and technical scheme of the utility model, and help its implementation.

[0022] As Figures 1 to 3As shown, the module end plate 1 includes an end plate body 11, the end plate body 11 is provided with a cross beam 12, the cross beam 12 is provided with a limiting support 14, and the end plate body 11 is also provided with a bundling groove 15. The bundling groove 15 is matched in size with the bundling belt 5, so that the bundling belt 5 can be flush with the outer surface of the end plate body 11 after being tightened, and the setting of the bundling groove 15 limits the movement of the bundling belt 5, so that it cannot be easily loosened. The module end plate 1 can greatly improve the carrying efficiency in the battery module production process in cooperation with the grabbing device.

[0023] As shown in Figure 1 and Figure 2 , the end plate body 11 is provided with vertical beams 13 on both sides, the vertical beams 13 are provided with bundling holes 131, and the vertical beams 13 are provided with lifting holes 132 at the top, and the lifting holes 132 are located above the bundling holes 131. The vertical beam 13 provides a mounting position for the lifting hole 132, eliminating the need for additional component installation, and the use of the lifting hole 132 will not affect the bundling belt 5. When manually temporarily carrying the module, and when the module needs to be adjusted and carried out after being put into the box, a hook can be used to lift and carry using the lifting hole 132, which is simple, safe and fast.

[0024] As shown in Figure 1 , the limiting supports 14 are oppositely arranged, the limiting supports 14 are provided with a gap 141 between them, and the limiting supports 14 are provided with a limiting portion 142 at the end. The limiting supports 14 are spaced apart by a certain distance to form a gap 141, which serves as a lifting position for the grabbing device, and the limiting portion 142 is a horizontal end at the top of the limiting support 14, which can be grabbed and released by the grabbing device. The limiting support 14 is L-shaped, and a T-shaped structure can also be used.

[0025] As shown in Figures 1 to 3 , the bundling groove 15 includes a first bundling groove 15 and a second bundling groove 15, the first bundling groove 15 and the second bundling groove 15 are arranged in parallel, the first bundling groove 15 is located between the bundling holes 131, and the second bundling groove 15 is located below the cross beam 12. The above structure, the bundling belt 5 located in the first bundling groove 15 is also limited by multiple bundling holes 131, and the bundling belt 5 located in the second bundling groove 15 is also blocked by the cross beam 12, so that the two bundling belts 5 are more difficult to separate, and the module stability is higher. The two bundling grooves 15 are located at the upper and lower parts of the end plate respectively, the fastening uniformity is good, and the space impact on the structure of the end plate is avoided, the end plate reliably limits the battery cell, which is conducive to improving the fixing stability of the module.

[0026] As shown in Figure 1 , the cross beam 12 is provided with mounting holes 121 at both ends. The mounting holes 121 realize the fixation of the module and the box body through the connecting piece.

[0027] The mounting hole 121 is a waist hole. Since the module is displaced due to tolerances after being put into the box, the mounting hole 121 is deviated from the position of the bolt hole of the box. By moving the module, the bolt hole of the box can be quickly located, and the working hours for fixing the module are greatly saved.

[0028] As shown in Figure 1 and Figure 2 The cross beam 12, the vertical beam 13 and the limiting support 14 are an integral structure. Integrally forming the above structure can effectively reduce the assembly times and realize the development of few parts.

[0029] The battery pack assembly comprises the module end plate.

[0030] As shown in Figures 1 to 3 The assembly method of the battery module is as follows: the battery cells are arranged into a battery pack in sequence, the module end plate 1 is placed at both ends of the battery pack, two binding belts 5 are used for binding and fixing, the binding belt 5 at the upper part of the end plate is pressed against the binding groove 15 and passes through the binding hole 131, the binding belt 5 at the lower part of the end plate is pressed against the binding groove 15 and abuts against the cross beam 12, the two binding belts 5 are tightened and locked, the binding belt 5 is closely attached to the binding groove 15, and the binding belt 5 is basically flush with the surface of the end plate body 11. Then, the whole module is fixed on the box by using the mounting hole 121.

[0031] The module end plate and the battery pack assembly have reasonable structure design, the lifting hole 132, the binding groove 15 and the mounting hole 121 structure are arranged, the production requirements of binding, carrying, temporary lifting and module fixing into the box of the module are met, the binding groove 15 is reasonably designed, the fixing reliability of the binding belt to the battery module is improved, the production efficiency is improved, and the safety is higher.

[0032] The utility model is described exemplarily above in combination with the drawings. Apparently, the specific implementation of the utility model is not limited by the above-mentioned mode. As long as various non-essential improvements are made by adopting the method concept and technical scheme of the utility model, or the above-mentioned concept and technical scheme of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
