Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to a mobile integrated energy storage unit. Background Technology

[0002] Mobile energy storage devices, such as outdoor power supplies or home emergency energy storage systems, primarily function to convert direct current (DC) stored in the form of battery modules into alternating current (AC) via an inverter for use by various electrical appliances. In recent years, with the continuous development of energy storage devices, users have increasingly higher requirements for home energy storage devices. These devices not only require high energy density but also portability, lightweight design, ease of transport, and expandable charging capabilities to meet diverse usage needs in daily home and outdoor scenarios.

[0003] In existing technologies, the structural forms of such devices are mainly divided into two types. The first is a split design, where the battery module and the inverter are two independent units, requiring external cable connections for use. This approach not only occupies a large area but also makes transportation, storage, and on-site deployment very inconvenient. The second is an integrated design, which houses the battery module, inverter, and related control components in a unified enclosure. In this integrated solution, handles are usually installed on the outside of the enclosure for easy handling; brackets are used to mount the inverter and other components to the inner wall or bottom plate of the enclosure to secure the internal components. For example, the structure of a home energy storage integrated unit can be referenced in Chinese Utility Model Patent Application No. CN202020179009.4, entitled "Home Energy Storage Integrated Unit." Currently, most home energy storage products are fixed and installed separately from the inverter, occupying a large area. The fixed structure is also difficult to move, failing to meet the needs of outdoor product usage scenarios.

[0004] However, the aforementioned integrated design still has structural flaws. When a user lifts or moves the entire device by the handle, the force applied is concentrated on the outer casing, while the weight of the heavy internal components, such as the inverter, is transferred to the inner wall of the casing through its mounting bracket. This means there is no direct structural connection between the external handling point (handle) and the main internal load-bearing components (inverter bracket); the force must be transmitted through the casing. During movement, especially during bumpy transport, this indirect mechanical structure can cause the connection points of the inverter mounting bracket to bear excessive shear force or vibration stress. Over time, this can easily lead to loose connections, component displacement, or even damage, thus affecting the overall reliability and lifespan of the device.

[0005] Therefore, how to optimize the internal mechanical structure of mobile energy storage units to achieve high integration and ease of movement while significantly enhancing the structural stability of core heavy components is an urgent problem to be solved. Utility Model Content

[0006] The technical problem to be solved by this utility model is: how to optimize the internal mechanical structure of the mobile energy storage unit and improve the structural stability of the internal core component inverter during movement and transportation.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a mobile energy storage integrated machine, including a box, the inside of which is divided into a control compartment and an energy storage compartment arranged vertically. An inverter bracket is provided in the control compartment, and an inverter body is provided on the inverter bracket. The inverter bracket is fastened to the inner wall of the box by fasteners. A handle extends through the side wall of the box into the control compartment and is fastened to the inverter bracket. A battery cell module is provided in the energy storage compartment, and the inverter body is electrically connected to the battery cell module.

[0008] Furthermore, the inverter bracket has opposing bent plates, and the handle is correspondingly locked onto the bent plates.

[0009] Furthermore, the inner wall of the enclosure is provided with a support frame, and the support frame is provided with a press-fit stud. The press-fit stud passes through the through holes on the insulating sheet and the inverter bracket and is locked with a nut.

[0010] Furthermore, the inverter bracket is equipped with a press-fit nut post, and the BMS is fastened to the press-fit nut post by screws. The BMS is electrically connected to the inverter body and the battery cell module respectively.

[0011] Furthermore, the inverter bracket has insulating column mounting bases and disconnector switch mounting bases welded on both sides of the BMS. The insulating column body is locked onto the insulating column mounting base, and the insulating column body is equipped with a fuse. The fuse is electrically connected to the inverter body and the battery cell module respectively. The disconnector switch mounting base is equipped with a fixing clip, and the disconnector switch body is fixed to the disconnector switch mounting base by the fixing clip.

[0012] Furthermore, a module fixing bracket is welded inside the energy storage compartment. The module fixing bracket is equipped with rivet nuts, and the battery cell module is fixed to the module fixing bracket by the rivet nuts.

[0013] Furthermore, an insulating strip is provided between the battery cell module and the inner wall of the energy storage compartment.

[0014] Furthermore, the side wall of the enclosure is provided with a photovoltaic charging port and / or a fast charging port that are electrically connected to the battery cell module.

[0015] Furthermore, the side wall of the enclosure is equipped with a display screen and a PCB board that communicate with the battery cell module.

[0016] Furthermore, the bottom of the housing is equipped with swivel casters and / or self-locking swivel casters.

[0017] The beneficial effects of this utility model are as follows: A mobile energy storage unit adopts an integrated compartmentalized structure design, dividing the product into an energy storage compartment and a control compartment. The stacked structure reduces the floor space occupied. The bottom of the box is set as the energy storage compartment, and a large-capacity battery cell module is installed at the bottom to lower the overall center of gravity of the product and improve its stability. At the same time, an insulating sheet is used to isolate the module from the outside to ensure its insulation. In order to stably install the inverter body in the control compartment, a handle mounting hole is provided on the inverter bracket. During installation, the handle is inserted from the corresponding hole on the side wall of the box and through the mounting hole on the side of the inverter bracket and then locked and fixed, so that the three become a whole, which plays a role in connecting and strengthening. Then the inverter body is stably installed on the inverter bracket. The inverter body is built into the control compartment of the box, which can achieve no interference between electrical signals, improve product stability, and reduce the space occupied by the equipment. It can be used for charging and discharging anytime and anywhere. The handle is used to fix the inverter bracket and facilitates the movement and handling of the energy storage compartment, improving the practicality of the product and meeting the needs of users in different scenarios. This utility model of a mobile energy storage unit integrates the inverter into the energy storage box, effectively isolating the device to improve its safety and reliability, achieving product integration, and allowing users to charge and discharge anytime and anywhere.
