[0026] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-Figure 6 As shown, the present embodiment provides an energy storage battery cabinet that is easy to disassemble and assemble, including a battery cabinet body 1 and a battery module 2. The battery cabinet body 1 is used to realize electrochemical energy storage and can accommodate one or more battery modules 2. The left and right sides of the interior of the battery cabinet body 1 are symmetrically provided with mounting rails 11 for supporting the battery module 2. The set position on the rail surface of the mounting rail 11 has a limiting groove 111 for cooperating with the roller assembly of the battery module. Roller assemblies 21 are provided on both sides of the bottom of the battery module 2. The roller assembly 21 is used to roll on the mounting rail to convert sliding friction into rolling friction, so as to facilitate the disassembly and assembly of the battery module 2 in the battery cabinet body 1. And the roller assembly 21 can be embedded in the limiting groove 111 to achieve limiting after the battery module 2 is installed in place.

[0028] In this embodiment, a roller assembly 21 is designed on the battery module, and a mounting rail 11 with a limiting groove 111 is designed in the battery cabinet body 1. The roller assembly can roll on the mounting rail and can be embedded in the limiting groove. The position of the limiting groove corresponds to the position of the roller assembly after the battery module is installed in place. During installation, the roller assembly is first aligned with the mounting rail, and then the battery module can be directly pushed in along the rail. When the roller assembly is embedded in the limiting groove, it indicates that the battery module has been pushed in place. When the battery module needs to be replaced, an outward pulling force is directly applied to make the roller assembly disengage from the limiting groove, and then the battery module can be easily taken out, and the disassembly and assembly process is simple and convenient. At the same time, the way of designing the roller assembly on the battery module can also facilitate the movement of the battery module outside the cabinet, which greatly improves the convenience of replacing the battery module.

[0029] A plurality of mounting rails 11 are arranged in the vertical direction inside the battery cabinet body 1 to form a multi-layer structure for supporting a plurality of battery modules. The number of mounting rails is determined comprehensively according to the volume of the battery cabinet body and the battery module, as well as the actual energy storage requirements, and the distance between adjacent mounting rails in the vertical direction is preferably slightly greater than the height of the battery module.

[0030] The battery module 2 preferably has roller assemblies 21 provided at all four corners of the bottom, so as to facilitate the disassembly and assembly of the battery module. At the same time, the four rollers can take into account the movement of the battery module outside the cabinet. For a battery module with a large weight, the design of the four roller assemblies not only facilitates the disassembly and assembly process inside the battery cabinet, but also facilitates the movement and transportation process outside the battery cabinet.

[0031] Correspondingly, a plurality of limiting grooves can be provided on the installation guide rail. The number of limiting grooves should not be less than the number of corresponding roller assemblies, and preferably the two are equal, so that when the battery module is pushed in place, all the roller assemblies can just be inserted into the limiting grooves at the corresponding positions. It is also possible to choose to make the number of limiting grooves greater than the number of roller assemblies. On the one hand, it can adapt to different specifications of battery modules. On the other hand, during disassembly and assembly, the battery module can be limited in a partially suspended state, so as to perform operations such as wiring and inspection on the battery module without removing the battery module.

[0032] The limiting groove 111 is formed by a retaining bar. A plurality of retaining bars are fixedly arranged on the guide rail surface of the installation guide rail 11. The retaining bars protrude from the guide rail surface, and there are gaps between adjacent retaining bars, thus forming the limiting groove. Taking one limiting groove as an example, as Figure 3 、 Figure 5 、 Figure 6 shown, the installation guide rail 11 is a U-shaped structure (in some embodiments, it can also be an L-shaped structure). The vertical side is used to be fixed on the inner wall of the battery cabinet body, and the upper surface of the horizontal side is used as the guide rail surface. A first retaining bar 112 and a second retaining bar 113 are fixedly arranged on the guide rail surface. There is a certain gap between the first retaining bar 112 and the second retaining bar 113, thus forming the limiting groove 111. The position where the retaining bar forms the limiting groove can be set as an inclined angle or a circular arc transition structure to facilitate the limiting of the roller assembly.

[0033] In this embodiment, the roller assembly is realized by the rolling of the bearing. As Figure 4 shown, the roller assembly 21 includes a mounting shaft 211, a bearing 212, a limiting plate 213, a bushing 214 and a shaft retaining ring 215. The mounting shaft 211 is a fixed shaft. The first end is fixedly connected to the side wall of the battery module 2, and the second end is used to mount the remaining components. The bearing 212 is sleeved on the second end of the mounting shaft and is sleeved on the mounting shaft. The limiting plate 213 is an L-shaped limiting plate. The first end is fixedly connected to the battery module 2, and the second end has an opening with a size matching that of the mounting shaft 211. A gap for accommodating the bearing 212 is formed between the limiting plate 213 and the battery module 2. The second end of the mounting shaft 211 passes through the opening at the second end of the limiting plate 213 and is fixed to the limiting plate 213 through the shaft retaining ring 215. Bushings 214 are provided between the outer wall of the bearing 212 and the battery module 2, and between the inner wall of the bearing 212 and the limiting plate 213, for limiting the bearing.

[0034] In some embodiments, the roller assembly can also be implemented using a traditional roller, in which case the roller assembly includes a mounting shaft and a roller, the first end of the mounting shaft is fixedly connected to the battery module, and the roller is rotatably connected to the mounting shaft. The roller can be made of a rigid structure such as stainless steel, or a flexible structure such as rubber or nylon.

[0035] In some embodiments, a handle may also be provided on the battery module 2. The handle is preferably provided on the end face of the battery module in the length direction, and the end face is the end face facing the outside of the battery cabinet body after the battery module is installed, so as to facilitate the technician to grasp when disassembling and installing the battery module.

[0036] The utility model provides an energy storage battery cabinet that is easy to disassemble and assemble. When installing a battery module, the roller assembly of the battery module is aligned with the installation rail, and then an inward thrust is applied from the outside of the battery module to push the battery module into the energy storage cabinet body. When the roller assembly is embedded in the limit groove, the battery module reaches a predetermined position and the limit is completed. At this time, the battery module can be additionally fixed as needed. When the battery module needs to be replaced or maintained, an outward pulling force is applied to the battery module to make the roller assembly disengage from the limit groove, and the battery module can be taken out.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
