Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery module technology, specifically to a battery module with a fixed block for separating positive and negative electrodes. Background Technology
[0002] A battery module is an assembly composed of multiple battery cells connected in series and parallel, primarily used to provide higher voltage and capacity. It is a crucial component of a battery system, typically consisting of battery cells, connectors, a battery management system (BMS), and a casing. Battery modules are widely used in electric vehicles, hybrid vehicles, energy storage systems, and other applications requiring high capacity and high voltage. They offer a higher level of battery energy storage and management to meet diverse power demands.
[0003] The positive and negative aluminum busbars of the module need to be firmly fixed, and the end plate is the best fixing position. However, the module end plates we usually use need to use metal end plates to fix the battery cells. Under normal circumstances, the metal end plate is a conductor and cannot be directly fixed to the positive and negative terminals. During the installation process, due to the accumulation of tolerances, the product cannot be installed quickly and the positioning is inaccurate.
[0004] Therefore, we propose a battery module with a fixed block for separating the positive and negative electrodes to solve the problems mentioned above. Utility Model Content
[0005] The purpose of this utility model is to provide a battery module with a blocking positive and negative electrode fixing block, in order to solve the problem mentioned in the background art that the positive and negative aluminum busbars of the module need to be firmly fixed, and the end plate is the best fixing position. However, the module end plates we generally use need to use metal end plates to fix the battery cells. Under normal circumstances, the metal end plate is a conductor and cannot directly fix the positive and negative electrodes. During the installation process, due to the accumulation of tolerances, the product cannot be installed quickly and the positioning is inaccurate.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a battery module with a positive and negative electrode fixing block, comprising a battery module body, characterized in that: end plates are fixedly provided at both ends of the battery module body, connecting grooves are provided on the end plates, a partition component is slidably installed in the connecting grooves, and positive and negative electrode aluminum busbars are fixedly provided at the upper end of the partition component; the partition component includes a partition base slidably connected in the connecting grooves, mounting grooves are provided on both sides of the upper end of the partition base, and bolts are slidably installed in the mounting grooves; sliding grooves are provided on both sides of the bottom of the mounting grooves, and sliders are slidably installed in the sliding grooves; a spring is fixedly installed between the side wall of the slider and the side wall of the sliding groove, and a clamping plate is fixedly installed at the upper end of the slider; the inner side of the upper end of the clamping plate is an arc-shaped surface; the positive and negative electrode aluminum busbars are fixedly connected to the bolts by screws.
[0007] Compared with the prior art, the beneficial effects of this utility model are:
[0008] 1. When assembling the battery module, first assemble the partition components into a whole, then slide the partition components along the connecting groove onto the end plate. After initially installing the partition components on the side of the battery module body, fix the partition components on both sides of the battery module body through the positive and negative aluminum busbars. In actual use, the battery module with the partition positive and negative fixing blocks is accurately positioned and can be installed quickly, which can improve the safety of the product.
[0009] 2. With the cooperation of the partition base, mounting groove, sliding groove, slider, clamping plate, spring, arc-shaped surface, and bolts, when assembling the partition assembly, the bolt is first slid along the mounting groove into the partition base for initial positioning. Once inside the mounting groove, the bolt first contacts the arc-shaped surfaces at the top of the two clamping plates, sliding downwards between them. As the bolt is pushed downwards, it presses the clamping plates to both sides. This pushing of the clamping plates causes the lower slider to slide outwards along the sliding groove, pushing the bolt to the appropriate depth. Under the action of the spring, the clamping plates on both sides automatically provide clamping and positioning for the bolt. At this point, the bolt and partition base can be fixed together by heat fusion. Then, the battery module installation is completed through the above steps. When using this device, the movable clamping plates can clamp and fix bolts of different diameters, initially clamping and positioning them in the middle of the mounting groove, facilitating subsequent fixing. It has strong applicability. Attached Figure Description

[0015] 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.
[0016] Example 1: Please refer to Figure 1 - Figure 3 A battery module with a fixed block for separating positive and negative electrodes includes a battery module body 1. Both ends of the battery module body 1 are fixedly provided with end plates 4. A connecting groove 41 is provided on the end plate 4. A separation component 3 is slidably installed in the connecting groove 41. A positive and negative electrode aluminum busbar 2 is fixedly provided at the upper end of the separation component 3.
[0017] In this embodiment: when assembling the battery module, the partition components 3 are first assembled into a whole, and then the partition components 3 are slidably installed on the end plate 4 along the connecting groove 41. After the partition components 3 are initially installed on the side of the battery module body 1, the partition components 3 are fixedly installed on both sides of the battery module body 1 by the positive and negative electrode aluminum busbars 2. When the battery module with the partition positive and negative electrode fixing blocks is used, the positioning is accurate and the installation is quick, which can improve the safety of the product.
[0018] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The partition assembly 3 includes a partition base 31 that is slidably connected in the connecting groove 41. The upper end of the partition base 31 has mounting grooves 311 on both sides. Bolts 32 are slidably installed in the mounting grooves 311. The bolts 32 can be connected to the partition base 31 through the mounting grooves 311.
[0019] Both sides of the bottom of the mounting groove 311 are provided with sliding grooves 312, and sliders 313 are slidably installed in the sliding grooves 312. The sliders 313 can slide along the sliding grooves 312 to both sides.
[0020] A spring 315 is fixedly installed between the side wall of the slider 313 and the side wall of the slide groove 312. A clamping plate 314 is fixedly installed on the upper end of the slider 313. The spring 315 initially provides the slider 313 with a pulling force towards the side of the slide groove 312.
[0021] The upper inner edge of the clamping plate 314 is an arc-shaped surface 316, which facilitates the insertion of the bolt 32.
[0022] The positive and negative aluminum busbars 2 are fixedly connected to the bolts 32 by screws, and the separator assembly 3 is fixed to the surface of the battery module body 1 by the positive and negative aluminum busbars 2.
[0023] In this embodiment: When assembling the partition component 3, the bolt 32 is first slid along the mounting groove 311 into the partition base 31 for initial positioning. The bolt 32 enters the mounting groove 311 and first contacts the arc-shaped surfaces 316 at the upper ends of the two clamping plates 314. It then slides downwards between the two arc-shaped surfaces 316. When the bolt 32 is pushed downwards, it presses the clamping plates 314 to both sides. As the clamping plates 314 are pushed to both sides, they cause the lower slider 313 to slide outwards along the sliding groove 312, thus positioning the bolt... Once bolt 32 is pushed to the appropriate depth, the clamping plates 314 on both sides automatically clamp and limit the bolt 32 under the action of spring 315. At this point, bolt 32 and partition base 31 can be fixedly connected together by heat fusion. Then, the installation of battery module is completed by the above steps. When using this device, bolts 32 of different diameters can be clamped and fixed by movable clamping plates 314. They can be initially clamped and limited in the middle of the mounting groove 311, which facilitates the subsequent fixing between the two. It has strong applicability.
