Description

Technical Field

[0001] The present application belongs to the technical field of container accessory manufacturing, and specifically relates to an energy storage battery module with a battery bracket that is easy to install and disassemble. Background Art

[0002] Usually, multiple battery modules are installed on the battery bracket in the energy storage container. The battery modules are connected in series to form a battery cluster, and multiple battery clusters form an energy storage system. With the rapid development of the energy storage market, the weight of the energy storage module is constantly increasing. The battery module is large in size, heavy in weight, and has a small installation space, making it difficult to install and disassemble.

[0003] Most installation methods are to place the battery module on the battery bracket and push it into the battery bracket through the production tooling. The battery module and the battery bracket will cause friction, which will cause damage to the paint surface of the battery module and the bracket. In serious cases, the two will be squeezed to produce metal debris, which poses certain safety hazards. Moreover, it is difficult to disassemble during on-site maintenance at the customer site without production tooling. Utility Model Content

[0004] The purpose of the present application is mainly to address the shortcomings of the prior art. A method of arranging a roller at the bottom of the battery module and a concave cavity on the bottom wall of the mounting cavity of the bracket is adopted to design an energy storage battery module with a battery bracket that is easy to install and disassemble, thereby reducing the friction between the battery module and the bracket during the process of installing the battery module in the mounting cavity. The concave cavity arranged on the bottom wall of the mounting cavity allows the roller to avoid after the battery module is installed in the concave mounting cavity, and the battery module will not be difficult to fix on the battery bracket due to the rolling of the roller on the bracket. The problem of friction between the battery module and the bottom wall of the mounting cavity during the process of the production tooling pushing the battery module into the mounting cavity on the bracket is solved, which may cause damage to the paint surface of the battery module and the bracket, and metal debris to be generated due to squeezing between the battery module and the mounting cavity is solved.

[0005] In order to achieve the above purpose, the technical solution adopted in this application is:

[0006] A storage battery module with a battery bracket that is easy to install and disassemble, comprises a bracket and a battery module, wherein the bracket is provided with an installation cavity for installing the battery module, rollers are provided at both the front and rear ends of the lower surface of the battery module, and concave cavities cooperating with the rollers are provided at both the front and rear ends of the lower surface of the installation cavity, the shape and size of the projection of the concave cavity on the lower surface of the installation cavity is larger than the size of the projection of the roller on the lower surface of the installation cavity, and the depth of the concave cavity is larger than the distance from the lower end of the roller to the lower surface of the battery module.

[0007] Preferably, the concave cavity is arc-shaped, the radius of the concave cavity is greater than the radius of the roller, and the width of the concave cavity is greater than the thickness of the roller.

[0008] Preferably, a slot is provided on the side wall of the battery module near the bottom wall, one end of the slot is on the side wall of the battery module, and the other end extends outside the bottom wall of the battery module toward the bottom wall of the battery module, the roller is installed in the slot, the rotation axis of the roller is parallel to the bottom wall of the battery module and perpendicular to the side wall of the battery module where the slot is provided, the side wall of the battery module where the slot is provided is provided with a cover plate that cooperates with the slot, and the lower end of the roller is lower than the lower surface of the battery module.

[0009] Preferably, at least two of the rollers are provided at the front end on the lower surface of the battery module, and the connection line between the two rollers is parallel to the front side wall of the battery module; at least two of the rollers are provided at the rear end on the lower surface of the battery module, and the connection line between the two rollers is parallel to the front side wall of the battery module; the projection of the battery module on the bottom wall of the mounting cavity is a rectangle.

[0011] Preferably, the cover plate is fixedly connected to the battery module by screws.

[0012] Compared with the prior art, this application has the following beneficial effects:

[0013] 1. The present application adopts a method of arranging a roller at the bottom of the battery module and arranging a concave cavity on the bottom wall of the mounting cavity of the bracket, and designs an energy storage battery module with a battery bracket that is easy to install and disassemble, thereby reducing the friction between the battery module and the bracket during the process of installing the battery module in the mounting cavity, and the concave cavity arranged on the bottom wall of the mounting cavity enables the roller to avoid after the battery module is installed in the concave mounting cavity, and the battery module will not be difficult to fix on the battery bracket due to the rolling of the roller on the bracket. The problem of friction between the battery module and the bottom wall of the mounting cavity during the process of the production tool pushing the battery module into the mounting cavity on the bracket is solved, which may cause damage to the paint surface of the battery module and the bracket, and metal debris may be generated due to compression between the battery module and the mounting cavity.

[0014] 2. The concave cavity in the present application is set to be an arc shape, the radius of the concave cavity is greater than the radius of the roller, and the width of the concave cavity is greater than the thickness of the roller, so that after the battery module is moved into place in the installation cavity, the rollers at the front and rear ends of the lower surface of the battery module can each fall into the concave cavity that matches it, so that the lower surface of the battery module contacts the inner bottom wall of the installation cavity, so that the problem of difficulty in fixing the battery module on the bracket will not be caused by the rollers rolling on the inner bottom wall of the installation cavity. At the same time, the arc-shaped design allows less material to be removed from the installation cavity when opening the concave cavity, thereby reducing the risk of the bottom wall of the installation cavity breaking.

[0015] 3. In the present application, due to the design of the notch, the width of the battery module will not increase after the roller is installed. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-6 As shown, an energy storage battery module with a battery bracket that is easy to install and disassemble includes a bracket 1 and a battery module 2. The bracket 1 is provided with a mounting cavity 3 for mounting the battery module 2. Rollers 4 are provided at both the front and rear ends of the lower surface of the battery module 2. Concave cavities 5 that cooperate with the rollers 4 are provided at both the front and rear ends of the lower surface of the mounting cavity 3. The shape and size of the projection of the concave cavity 5 on the lower surface of the mounting cavity 3 are larger than the size of the projection of the roller 4 on the lower surface of the mounting cavity 3. The depth of the concave cavity 5 is greater than the distance from the lower end of the roller 4 to the lower surface of the battery module 2.

[0024] In the present embodiment, generally speaking, the opening of the mounting cavity 3 is located on the front surface of the bracket 1, that is, the opening direction of the mounting cavity 3 is parallel to the upper surface of the bracket 1. In the process of installing the battery module 2 in the mounting cavity 3, the rear end of the battery module 2 (the end of the battery module 2 facing the front of the bracket 1 after the battery module 2 is installed in the mounting cavity 3 is the front end of the battery module 2) is first placed in the mounting cavity 3. Since rollers 4 are provided at both the front and rear ends of the lower surface of the battery module 2, at this time, in the process of the production tool pushing the battery module 2 to move into the mounting cavity 3, the roller 4 at the rear end of the lower surface of the battery module 2 first contacts the inner bottom wall of the mounting cavity 3 and the bracket 1 is moved. The battery module 2 is supported and rolled. After the battery module 2 moves to a certain distance into the mounting cavity 3, the front roller 4 on the lower surface of the battery module 2 contacts the inner bottom wall of the mounting cavity 3 and supports the battery module 2 to move into the mounting cavity 3 together with the rear roller 4 located on the lower surface of the battery module 2. After the battery module 2 moves into place in the mounting cavity 3, the rollers 4 at the front and rear ends on the lower surface of the battery module 2 respectively fall into the corresponding concave cavities 5, so that the lower surface of the battery module 2 contacts the inner bottom wall of the mounting cavity 3, so that the battery module 2 will not be difficult to fix on the bracket 1 due to the rolling of the roller 4 on the inner bottom wall of the mounting cavity 3.

[0025] As a preferred embodiment, the concave cavity 5 is arc-shaped, the radius of the concave cavity 5 is greater than the radius of the roller 4, and the width of the concave cavity 5 is greater than the thickness of the roller 4. With this design, after the battery module 2 is moved into position in the mounting cavity 3, the rollers 4 at the front and rear ends of the lower surface of the battery module 2 can each fall into the concave cavity 5 that matches with it, so that the lower surface of the battery module 2 contacts the inner bottom wall of the mounting cavity 3, so that the problem of difficulty in fixing the battery module 2 on the bracket 1 will not occur due to the rolling of the rollers 4 on the inner bottom wall of the mounting cavity 3. At the same time, the arc-shaped design allows less material in the mounting cavity 3 to be removed when the concave cavity 5 is opened, thereby reducing the risk of the bottom wall of the mounting cavity 3 breaking.

[0026] As a preferred method, a slot 6 is provided on the side wall of the battery module 2 near the bottom wall, one end of the slot 6 is on the side wall of the battery module 2, and the other end extends toward the bottom wall of the battery module 2 to the outside of the bottom wall of the battery module 2, the roller 4 is installed in the slot 6, the rotation axis of the roller 4 is parallel to the bottom wall of the battery module 2 and perpendicular to the side wall of the battery module 2 where the slot 6 is provided, the side wall of the battery module 2 where the slot 6 is provided is provided with a cover plate 7 that matches the slot 6, and the lower end of the roller 4 is lower than the lower surface of the battery module 2. This design method facilitates the installation of the roller 4, and at the same time, due to the design of the slot 6, the width of the battery module 2 will not increase after the roller 4 is installed.

[0027] As a preferred mode, at least two rollers 4 are provided at the front end of the lower surface of the battery module 2, and the connection line between the two rollers 4 is parallel to the front side wall of the battery module 2. At least two rollers 4 are provided at the rear end of the lower surface of the battery module 2, and the connection line between the two rollers 4 is parallel to the front side wall of the battery module 2. The projection of the battery module 2 on the bottom wall of the installation cavity 3 is a rectangle. This design mode is to enable the rollers 4 to evenly distribute the weight of the battery module 2, so that the battery module 2 can roll smoothly in the installation cavity 3.

[0028] As a preferred embodiment, at least two mounting cavities 3 are provided on the bracket 1, and one battery module 2 is installed in each mounting cavity 3. This design allows multiple battery modules 2 to be installed on one bracket 1, achieving the purpose of installing multiple battery modules 2 on the bracket 1 and connecting the battery modules 2 in series to form a battery cluster, and multiple battery clusters form an energy storage system.

[0029] As a preferred mode, the cover plate 7 is fixedly connected to the battery module 2 by screws. With this design, it is easy to disassemble the cover plate 7 and to inspect (eliminate) the roller 4 when it fails (for example, it is stuck).
