Description

Technical Field

[0001] The utility model belongs to the technical field of new energy, and particularly relates to a new energy module. Background Art

[0002] At present, the design of new energy battery packs is developing rapidly, mainly based on square cells and cylindrical cells. Among them, square cells have higher energy density and are therefore more widely used. The module of the square cell is mainly composed of cells, end plates, spacers, output pole bases, output pole protective covers, series-connected high-voltage copper busbars and low-voltage collection components. The common output pole protective cover is generally made of plastic. The two exposed parts of the copper busbar are shielded and protected by the buckle structure and the output pole base. However, during the assembly process of a single module, the copper busbar cannot be completely protected. The high-voltage output busbar is easily touched during disassembly and assembly. In addition, the size is very small, and the buckle structure is easily damaged and fails during disassembly and assembly. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] A new energy module, such as Figure 1 As shown, it includes an end plate 1, a copper busbar 2, a protective cover 3, an output pole 4 and a base 5. The two sides of the end plate 1 have reserved mounting positions, and the two bases 5 are respectively mounted on the mounting positions on the two sides of the end plate 1, and can be fixedly connected or detachably connected to the end plate 1. The number of output poles 4 corresponds to the base 5, which is overlapped on the base 5, and then the joints 201 at both ends of the copper busbar 2 are overlapped on the output pole 4. The protective cover 3 is connected to the end plate 1 in a detachable manner, and can cover the entire copper busbar 2, thereby protecting the copper busbar 2.

[0034] It should be noted that Figure 1The purpose of the middle structure is to completely protect the exposed copper busbar 2 at the output pole 4 of the module, and at the same time protect the copper busbar 2 when the module is put into the box to prevent the box or other parts from scratching the insulation skin of the copper busbar 2; in the process of module assembly, the battery cells are first stacked, and then the collection component (the output pole 4 is the output end of the collection component) is welded to the battery cell pole, and then the copper busbar 2 of the module and the output pole 4 of the collection component are matched, and then the output pole 4 and the base 5 are tightened by bolts, and the copper busbar 2 and the output pole 4 of the collection component are clamped, and then the protective cover 3 and the end plate 1 are matched. The entire length of the protective cover 3 can include both ends of the end plate 1 including the output pole 4, and then the main part of the protective cover 3 also wraps the insulating skin of the copper busbar 2. The effect after wrapping is as follows: Figure 2 As shown, the protective cover 3 covers the copper bus 2, and a certain gap is left between the main part of the copper bus 2 and the main part of the protective cover 3.

[0035] Furthermore, if Figure 3 As shown, the end plate 1 is a symmetrical structure, with four notches at both ends, two of which are located at the upper left corner and the upper right corner of the end plate 1, and two notches are located in the middle of both ends of the end plate 1, and two upper mounting seats 102 and two lower mounting seats 103 are formed by the four notches. The base 5 is installed on the lower mounting seat 103. In addition, the interior of the end plate 1 is a hollow structure with several partitions, and four positioning holes 101 are opened on the surface of the end plate 1, and the opening position of the positioning holes 101 is located on the surface of the hollow structure.

[0036] It should be noted that in Figure 3 The middle end plate 1 has six hollow structures and four positioning holes 101 , wherein the hollow structures on both sides are provided with positioning holes 101 , and the positioning holes 101 are staggered.

[0037] Furthermore, if Figure 4 As shown, the main body of the copper busbar 2 is in a strip shape, and the joints 201 at both ends can be bent vertically to the main body so that the joints 201 can overlap the output pole 4.

[0038] Furthermore, if Figure 5 As shown, the protective cover 3 is U-shaped, and a U-shaped groove 303 is provided on a surface facing the copper busbar 2; a buckle 302 is also provided on the edge of the protective cover 3 facing the copper busbar 2, and the buckle 302 is snapped into the positioning hole 101. There are four buckles 302, which are symmetrically arranged on the upper and lower edges of the protective cover 3 and staggered. In addition, the two sides of the protective cover 3 are end covers 301, which are used to protect the output pole 4, and the surface of the end cover 301 facing the output pole 4 is provided with a notch.

[0039] It should be noted that the buckles 302 are distributed on both sides of the copper busbar 2 to ensure uniform force after fixation; after installation, the buckles 302 will be inserted into the rectangular positioning holes 101 opened on the end plate 1, and then the buckles 302 of the protective cover 3 will buckle the end plate 1 upside down. After the protective cover 3 is assembled in place, the U-shaped groove 303 and the copper busbar 2 still maintain a certain distance, which can leave a certain buffer margin for the impact process. During the subsequent hoisting process of the module, the copper busbar 2 can avoid the risk of being subjected to force when it hits the box, resulting in loose connection with the output pole 4 of the collection component and damage to the insulation skin of the copper busbar 2.

[0040] It should be further explained that the buckle 302 has a certain amount of deformation, which allows it to pass through the rectangular positioning hole 101 on the end plate 1 and buckle the end plate 1. The buckles 302 are distributed on both sides of the copper bus 2 and are staggered, which can alleviate the problem of excessive stress on the components themselves during the installation of the buckles 302.

[0041] Furthermore, the protective cover 3, the connector 201, the output pole 4 and the base 5 are connected in sequence by bolts.

[0042] Furthermore, a plurality of first reinforcing ribs 304 are provided at the contact position between the protective cover 3 and the end plate 1 to increase the contact area with the end plate 1, increase the support width, and maintain better stability. In addition, second reinforcing ribs 305 are provided at the protection position of the middle copper bar 2 and the protection position of the output pole 4 to prevent the deformation of the parts and cause dimensional instability. Moreover, the protective cover 3 is provided with ribs near the end plate 1 to separate the end plate 1 and the output pole 4 to maintain a safe electrical gap.

[0043] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
