Description

Technical Field

[0001] This utility model relates to the field of battery module technology, and more specifically, to an outer protective shell for a battery module. Background Technology

[0002] A battery module typically refers to a larger energy storage unit composed of multiple battery cells (also known as battery cells) connected in series, parallel, or a combination thereof. This combination method can meet specific voltage, capacity, and power requirements and is widely used in energy storage systems, industrial vehicles, and other fields.

[0003] Currently, most battery modules use straps to bind multiple battery cells together. However, this method is not effective in fixing and protecting the battery module. Especially when the battery module is used in equipment that moves frequently and for long periods of time, such as industrial vehicles, the battery module is prone to displacement or even separation, resulting in a high failure rate and poor safety, which affects the normal use of the battery module.

[0004] Therefore, it is necessary to provide an outer casing for a battery module to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide an outer protective shell for a battery module to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An outer casing for a battery module, comprising: Two side guards are provided on the left and right sides of the battery module, and the bottom of the side guards is provided with a support plate for supporting the battery module. Two end guards are disposed at the front and rear ends of the battery module, and the left and right sides of each end guard are respectively connected to the two side guards; A top plate is disposed above the battery module, and the top plate is connected to the two side guard plates; The mounting plate is vertically mounted on the outer wall of the end guard plate.

[0007] Furthermore, the end guard plate is provided with side connecting plates at both the left and right ends, and the side connecting plates are provided with multiple first side holes. The front and rear ends of the side guard plate are provided with multiple second side holes that are adapted to the first side holes.

[0008] Furthermore, a top connecting plate is provided at the upper end of the side guard plate, and a plurality of first top holes are provided on the top connecting plate. A plurality of second top holes that are adapted to the first top holes are provided on both the left and right sides of the top plate.

[0009] Furthermore, it also includes: A protective box is used to house multiple battery modules. Both the front and rear ends of the protective box are provided with mounting structures for connecting with end guards.

[0010] Furthermore, the installation structure includes a limiting plate disposed inside the protective box, the limiting plate being provided with a plurality of limiting posts, and the mounting plate of the end guard plate being provided with a limiting groove adapted to the limiting posts.

[0011] Furthermore, insulating pads are provided on the side of the side guard plate and the bottom plate near the battery module.

[0012] Furthermore, the end guard plate is provided with a first hanging ear, and the protective box is provided with a second hanging ear at both the front and rear ends.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In this design, two side guards are placed on the left and right sides of the battery module, and two end guards are placed at the front and rear ends of the battery module. The end guards are then connected to the side guards. Finally, the top plate is connected to the side guards. This design limits and protects the multiple battery cells in the battery module, unlike the current method of binding them together with straps. Especially when the battery module is used in equipment that moves frequently and for extended periods, such as industrial vehicles, this design greatly prevents the battery cells within the module from shifting or even separating. Furthermore, the protection of the battery module prevents the battery cells from being directly damaged by impacts, reducing the failure rate, improving the safety of the battery module, and ensuring its normal operation.

[0016] 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.

[0017] Please see Figure 1-10 An outer casing for a battery module, comprising: Two side guards 2 are provided on the left and right sides of the battery module 1, and the bottom of the side guards 2 is provided with a bottom plate 4 for supporting the battery module 1. Two end guards 3 are disposed at the front and rear ends of the battery module 1, and the left and right sides of each end guard 3 are respectively connected to two side guards 2. The top plate 5 is located above the battery module 1 and is connected to the two side guard plates 2. Mounting plate 6 is vertically mounted on the outer wall of end guard plate 3.

[0018] In use, place the two side guards 2 on the left and right sides of the battery module 1 respectively, and make the bottom plate 4 contact the bottom of the battery module 1. Then place the two end guards 3 at the front and rear ends of the battery module 1 respectively, and make the end guards 3 between the two side guards 2. Then connect the end guards 3 with the two side guards 2. Then place the top plate 5 on top of the battery module 1 and connect the top plate 5 with the side guards 2. The battery module 1 is encased together by the side guard plate 2, end guard plate 3, and top plate 5, which limits and protects the battery module 1. This method differs from the current method of binding the battery modules together with straps. Especially when the battery module 1 is used in equipment that moves frequently and for long periods, such as industrial vehicles, the limiting and protective function of the side guard plate 2, end guard plate 3, and top plate 5 can greatly prevent the battery cells in the battery module 1 from shifting or even separating. Furthermore, the protection of the battery module 1 can prevent the battery cells from being directly damaged by impacts, reduce the failure rate, improve the safety of the battery module 1, and ensure its normal use. It is highly practical.

[0019] Mounting plate 6 can install the outer casing of battery module 1 into the equipment in use, making it convenient to limit and fix battery module 1.

[0020] For preferred options, please refer to [link / reference]. Figure 1-6 Both ends of the end guard plate 3 are provided with side connecting plates 7, and multiple first side holes 8 are provided on the side connecting plates 7. Both ends of the side guard plate 2 are provided with multiple second side holes 9 that are adapted to the first side holes 8.

[0021] Specifically, when connecting the end guard plate 3 and the side guard plate 2, the two side connecting plates 7 on the end guard plate 3 are respectively in contact with the side guard plates 2 on both sides, and the first side hole 8 on the side connecting plate 7 is aligned with the second side hole 9 on the side guard plate 2. Then, rivets or screws are used to pass through the first side hole 8 and the second side hole 9 to fix the end guard plate 3 and the side guard plate 2 together.

[0022] In this embodiment, preferably, please refer to 1-2 and Figure 5-6 The upper end of the side guard plate 2 is provided with a top connecting plate 10, and the top connecting plate 10 is provided with a plurality of first top holes 11. The left and right sides of the top plate 5 are provided with a plurality of second top holes 12 that are adapted to the first top holes 11.

[0023] Specifically, after connecting the end guard plate 3 and the side guard plate 2, the top plate 5 is placed on the top of the battery module 1, so that the top plate 5 contacts the top connecting plate 10 of the side guard plate 2, and the second top hole 12 of the top plate 5 is aligned with the first top hole 11 of the top connecting plate 10. Then, rivets or screws are used to pass through the first top hole 11 and the second top hole 12 to fix the top plate 5 and the side guard plate 2 together.

[0024] In this embodiment, preferably, please refer to [reference needed]. Figure 3-6 Insulating pads 17 are provided on the side of the side guard plate 2 and the bottom plate 4 near the battery module 1. This design ensures electrical isolation and physical protection between the battery cells in the battery module 1 and the side guard plate 2 and the bottom plate 4, ensuring the safe operation of the battery and the stability of the entire battery module 1. In addition, the insulating pads 17 are made of flexible material, which can further protect the battery cells.

[0025] For preferred options, please refer to [link / reference]. Figure 7-10 It also includes: The protective box 13 is used to house multiple battery modules 1. Both the front and rear ends of the protective box 13 are provided with mounting structures for connecting with the end guard plate 3.

[0026] This design allows for the placement and protection of multiple battery modules 1 within the protective housing after the battery module 1 is secured by the outer casing. The protective housing 13 is then connected to the end guard plate 3 via its mounting structure. This enables the layout and installation of the battery modules 1 with their outer casings. The protective housing 13 provides further protection for the multiple battery modules 1. The protective housing 13 facilitates the overall installation of the multiple battery modules 1 on the equipment, resulting in better protection and further enhancing the safety performance of the battery modules 1.

[0027] In this embodiment, preferably, please refer to [reference needed].

[0028] With this design, when the battery module 1 is placed in the protective box 13, the mounting plate 6 of the end guard plate 3 contacts the limiting plate 14, and the limiting groove 16 of the mounting plate 6 aligns with the limiting post 15 on the limiting plate 14. The limiting post 15 can then limit the mounting plate 6 and the end guard plate 3, thereby limiting the side guard plate 2, the top plate 5, and the battery module 1. In other words, the battery module 1 is confined in the protective box 13, ensuring the overall stability of the battery module 1.

[0029] In addition, the limiting post 15 can be set as a threaded post, and the nut and the limiting post 15 can be used to press the nut to the mounting plate 6, thereby further limiting the mounting plate 6 and the battery module 1 as a whole, which can further improve the stability of the battery module 1.
