Description

Technical Field

[0001] This utility model belongs to the field of battery module technology, and in particular relates to a reinforced battery module fixing structure. Background Technology

[0002] Currently, the mainstream method for fixing large-capacity aluminum-cased square battery modules involves using holes in the aluminum plates at both ends of the battery module, along with four long screws that engage with the external base plate for fixation. Additionally, adhesive is added between the insulating and heat-resistant materials between the batteries to increase friction and thus enhance the overall module's strength. However, when the number of batteries in the module is excessive or the batteries are heavy, relying solely on this method for module fixation has limited effectiveness in the Z-axis direction. If the battery pack is subjected to vibrations or movement, the screw connections may fail, causing module displacement and misalignment, leading to product problems. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a reinforced battery module fixing structure, which adds an insulating bracket to reinforce the battery module in the Z direction. The inner top surface of the insulating bracket has multiple integrally formed pressure blocks that apply downward pressure evenly to each battery, ensuring the fixing strength of the entire battery module in the Z direction.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a reinforced battery module fixing structure is provided, the fixing structure includes a base and an insulating bracket, the two ends of the base are provided with raised steps, the battery module is placed between the two steps and the battery module is positioned by the two steps; a row of first mounting holes is reserved on each side of the base, and multiple second mounting holes are also reserved on the steps;

[0005] The insulating bracket is a U-shaped bracket. The two lower edges of the insulating bracket extend to form a horizontal mounting part. The mounting part is provided with a third mounting hole that matches the first mounting hole. The inner top surface of the insulating bracket has multiple pressure blocks. The insulating bracket is snapped into the base from above and fixedly connected to the base. At the same time, the pressure blocks will abut against the upper part of the battery module.

[0006] Both ends of the battery module are equipped with side plates. The side plates are provided with a fourth mounting hole extending in the Z direction. The battery module is fixed to the base by passing a long screw through the second mounting hole and the fourth mounting hole.

[0007] The insulating bracket is secured to the base by fasteners passing through the first and third mounting holes.

[0008] Furthermore, the insulating support is a PPO material support; the insulating support and its pressure block are integrally formed and connected.

[0009] Furthermore, the inner top surface of the insulating bracket has two rows of pressure blocks, which are staggered.

[0010] To elaborate further, the fastener is a screw.

[0011] Furthermore, the lower part of the insulating bracket is located inside the base, and the two ends of the bottom of the insulating bracket abut against the side of the step.

[0012] The beneficial effects of this utility model are:

[0013] This utility model includes a base and an insulating bracket. Based on the original battery module fixing method, an insulating bracket is added to reinforce the battery module in the Z direction. The inner top surface of the insulating bracket has multiple integrally formed pressure blocks. During installation, the pressure blocks avoid the components and busbars above the battery module and apply downward pressure evenly to each battery, ensuring the fixing strength of the entire battery module in the Z direction, increasing the fixing effect of the battery module, and avoiding problems such as battery displacement or misalignment under bumpy or moving conditions.

[0024] Example: A reinforced battery module fixing structure, such as Figures 1 to 5 As shown, the fixing structure includes a base 1 and an insulating bracket 2. The base has raised steps 11 at both ends. The battery module 3 is placed between the two steps and positioned by the two steps. A row of first mounting holes 12 is reserved on each side of the base, and multiple second mounting holes 13 are also reserved on the steps.

[0025] The insulating bracket is a U-shaped bracket. The two lower edges of the insulating bracket extend to form a horizontal mounting part 21. The mounting part is provided with a third mounting hole 22 that matches the first mounting hole. The inner top surface of the insulating bracket has multiple pressure blocks 23. The insulating bracket is snapped into the base from above and fixedly connected to the base. At the same time, the pressure blocks will abut against the upper part of the battery module.

[0026] Both ends of the battery module are equipped with side plates 31. The side plates are provided with a fourth mounting hole 32 extending in the Z direction. The battery module is fixed to the base by passing through the second mounting hole and the fourth mounting hole with a long screw (not shown in the figure).

[0027] The insulating bracket is secured to the base by fastener 4 passing through the first and third mounting holes.

[0028] In this embodiment, the insulating support is a PPO (polyphenylene oxide) material support; the insulating support and its pressure block are integrally molded and connected. The entire insulating support can be manufactured using injection molding. First, an injection mold is created according to the shape of the insulating support. The PPO raw material is heated to a molten state and then poured in through the injection port of the mold. After pouring, it is allowed to cool and solidify, making it easy to process and shape.

[0029] In this embodiment, the inner top surface of the insulating bracket has two rows of pressure blocks, which are staggered to avoid obstructing components and busbars above the battery module.

[0030] In this embodiment, the fastener is a screw, but other fasteners can also be used as long as they can achieve the purpose of fixing and installing.

[0031] In this embodiment, the lower part of the insulating bracket is located inside the base, and the two ends of the bottom of the insulating bracket abut against the sides of the steps. This facilitates the positioning and installation of the insulating bracket; the insulating bracket is simply inserted between the two steps to indicate that it is in place.

[0032] The working process and working principle of this utility model are as follows:

[0033] Prepare the first and second mounting holes on the entire base. Then, insert the battery module between the two steps and fix the battery module to the base by passing the long screw through the second and fourth mounting holes. Then, attach the insulating bracket to the battery module from above and adjust the position of the insulating bracket to ensure that it does not interfere with the components and busbars above the battery module. Use fasteners to connect the insulating bracket to the base through the first and third mounting holes to assemble. The whole installation process is very quick and convenient.
