Description

Technical Field

[0001] This utility model belongs to the field of module battery technology, and in particular to a battery pack and its output electrode connection structure. Background Technology

[0002] Currently, the common electrode fixing bases for module and output electrode connection structures on the market only have a single-sided outlet design, that is, a design facing away from the end of the battery pack. When connecting the copper busbars of adjacent modules, i.e. the side battery pack, the copper busbars need to be bent to avoid it, which increases the bending process cost. In addition, the copper busbars are longer, heavier, and more expensive, and they also take up space. If the modules are directly connected, the insulating cover cannot be installed normally, and only the nut and plastic cap are used for protection, which poses a risk of falling off. Utility Model Content

[0003] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the single-sided outlet design of the output electrode fixing seat, which requires the copper busbar to be bent to avoid the adjacent module copper busbar when connecting, resulting in longer copper busbars, heavier weight, higher cost, and space occupation, or direct bridging between modules, but the insulating cover cannot be installed, and only the nut and plastic cap are used for protection, which poses a risk of falling off. Therefore, a battery pack and its output electrode connection structure are proposed.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A battery pack and its output electrode connection structure include an output electrode fixing seat disposed on the end plate of the battery pack, an output electrode sheet located inside the output electrode fixing seat, and a protective cover on the output electrode fixing seat.

[0006] The output electrode mounting bracket includes a pair of front brackets, a pair of rear brackets, and a base. The base is horizontally connected to the battery pack end plate, and the pair of front brackets and the pair of rear brackets are vertically fixed to the four corners of the base. The output electrode is located on the base and fixed by nuts.

[0007] The front bracket is located away from the battery pack side, and the rear bracket is located close to the battery pack side. A copper busbar mounting port facing outward from the end of the battery pack is formed between the two front brackets, and a copper busbar mounting port facing outward from the side of the battery pack is formed between a front bracket and a rear bracket on the same side.

[0008] As a further preferred embodiment, the protective cover includes a cover plate and a pressing edge, the cover plate being mounted on a pair of front supports and a pair of rear supports, and the pressing edge being located at the edge of the cover plate between the pair of front supports.

[0009] As a further preferred option, the top of a pair of front brackets and a pair of rear brackets are provided with buckles, and the cover plate has a slot corresponding to each buckle.

[0010] As a further preferred option, the upper edge of the battery pack end plate is provided with a U-shaped slot for accommodating and positioning the output terminal fixing seat.

[0011] As a further preferred embodiment, the U-shaped slot has vertically arranged slots on both sides, and the limiting structure is a boss structure for inserting into the slot.

[0012] As a further preferred option, the upper edge of the battery pack end plate is provided with at least one U-shaped slot.

[0013] As a further preferred option, the copper busbar mounting port one has a size of 39×9mm, and the copper busbar mounting port two has a size of 18.6×8mm.

[0014] As a further preferred option, the base has limiting structures on both sides that mate with the U-shaped grooves.

[0015] In this invention, the output pole fixing base adopts a bidirectional connectable copper busbar method, and the bracket is cleverly designed to achieve a snap-fit ​​cover plate connection, thereby achieving insulation protection and ensuring safety. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

The CCS component located inside the battery pack has an output electrode 3 at its end, which extends out of the battery pack and is positioned in the output electrode fixing seat 2. A copper busbar is mounted on the output electrode 3 in the output electrode fixing seat 2, one end of which can be electrically connected to other battery packs. Example 1

[0027] The output electrode mounting base 2 includes a pair of front brackets 4, a pair of rear brackets 5, and a base 6. The base 6 is horizontally connected to the battery pack end plate 1. The pair of front brackets 4 and the pair of rear brackets 5 are vertically fixed to the four corners of the base 6. The output electrode 3 is located on the base 6 and fixed by nuts.

[0028] The front bracket 4 is located away from the battery pack side, and the rear bracket 5 is located close to the battery pack side. A copper busbar mounting port 7 is formed between the two front brackets 4, pointing outward from the end of the battery pack, and a copper busbar mounting port 8 is formed between one front bracket 4 and one rear bracket 5 on the same side, pointing outward from the side of the battery pack.

[0029] The openings of copper busbar mounting port 1 (7) and copper busbar mounting port 2 (8) are perpendicular to each other. That is, copper busbar mounting port 1 (7) is set along the length of the battery pack, and copper busbar mounting port 2 (8) is set along the width of the battery pack. When connecting to adjacent battery packs through copper busbars, there is no need to change the structure or direction of the copper busbars, and they can be selectively connected directly.

[0030] The output electrode fixing base 2 of this utility model has a bidirectional opening design, which enables direct bridging of copper busbars in any direction between modules, saving installation space, materials, and time and labor costs associated with bending processes.

[0031] Furthermore, the protective cover 15 includes a cover plate 9 and a pressing edge 10. The cover plate 9 is mounted on a pair of front brackets 4 and a pair of rear brackets 5. The pressing edge 10 is located at the edge of the cover plate 9 between the pair of front brackets 4. The pressing edge 10 can be cut to increase the clamping and positioning of the copper busbar. Example 2

[0032] The top of the pair of front brackets 4 and the pair of rear brackets 5 of this utility model are provided with buckles 11, and the cover plate 9 has a slot 12 that corresponds to each buckle 11. Through the ingenious bracket design, the buckle-type protective cover 15 is tightly fastened, the structure is safer and more reliable, it is not easy to fall off, and it achieves insulation protection and ensures safety.

[0033] In addition, the upper edge of the battery pack end plate 1 is provided with a U-shaped slot 13 for accommodating and positioning the output pole fixing seat 2, and the base 6 has limiting structures 14 on both sides that cooperate with the U-shaped slot 13; thus realizing the detachable installation of the output pole fixing seat 2, and also serving as a limiting function.

[0034] In this utility model, the front bracket 4 and the rear bracket 5 are 20-25mm high, the buckle 11 protrudes 1-2.5mm high and is set at an angle to facilitate the guide and sliding of the protective cover. After installation, copper busbar mounting port 1 7 and copper busbar mounting port 2 8 are formed between the four brackets of the output pole fixing seat and the protective cover.

[0035] The copper busbar mounting port 1 (size 7) is 39×9mm, and the copper busbar mounting port 2 (size 8) is 18.6×8mm. The copper busbar can be installed in both horizontal and vertical directions according to the battery pack layout and connection requirements. The output terminal fixing base and protective cover are injection molded from ABS and PC materials, which are lightweight, low cost, and have good toughness. The snap-fit ​​structure design ensures tight installation and safety.
